JP 2001-001966 A (Detailed description of the invention, drawings) Japanese Patent Application Laid-Open No. 2004-1000033 (Abstract)

  In the conventional wheel lock device described in Patent Document 1, a pair of locking arms can be driven by a driving force of a motor to lock a wheel. However, in this wheel lock device, when the parked car is forced to escape, that is, just to escape, the force acts in the direction in which the locking arm as the wheel restraining member opens.

  Furthermore, in the conventional wheel lock device described in Patent Document 2, the operation plate is locked or released by the driving force of the solenoid to lock or release the wheel. However, even in the case of this wheel lock device, if the parked car just tries to escape, the de-outputting works in the direction in which the lock lever as the wheel restraining member opens.

  If the output force acts in such a direction that the wheel restraining member opens at the time of escape, the person who just wants to escape judges that the escape is possible and tries to escape by applying more force. For this reason, the mechanism must be able to withstand extremely strong force, and the mechanism tends to be enlarged. Also, if force is applied in the opening direction, the wheel restraining member will always open when trying to escape, and if rattling or deflection of parts is added, the gap will be close to the wheel width and there is a risk that it will just escape. Rise.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a wheel locking device, a parking system, and a driving method for a parking lock arm that can prevent or reduce illegal forced escape. .

  In order to solve the above-described problem, the wheel lock device of the present invention includes a lock arm that locks a wheel, and a drive source that rotates the lock arm around a fulcrum, and the lock arm rotates in one direction. In the wheel lock device where the lock arm closes by moving and enters the locked state of the wheel, and the lock arm opens by turning in the other direction, the wheel is released, trying to escape the locked wheel from the locked state, When the wheel is moved in the direction opposite to the insertion direction, the lock arm is rotated in one direction by the de-output.

  According to this configuration, if you try to escape illegally and try to pull out the wheel, the lock arm moves in the closing direction, so those who just try to escape or those who try to steal will tend to give up continuation of the act, Illegal forced escape is prevented or reduced. In addition, since the lock arm moves in the closing direction, even if there is a backlash or deflection of the part, it is not possible to obtain a sufficient opening to escape, and also in this aspect, illegal forced escape is prevented or reduced. Therefore, the forced escape which exceeds the assumption is not performed, and the enlargement of the mechanism can be avoided, the apparatus can be downsized, and the cost is advantageous.

  In addition to the above-described invention, the wheel lock device of another invention includes a motor that rotates the output shaft by energization, a cam that rotates together with the output shaft, a hole that is formed in the lock arm and into which the cam is inserted, And a fulcrum support shaft provided at a position where the force acting on the action point of the de-outputting turns in one direction of the lock arm. According to this configuration, the lock arm can be swung by rotating the cam. Therefore, the lock arm can be opened and closed using a simple motor capable of rotating the output shaft in one direction by energization.

  In addition to the configuration of the invention described above, two wheel lock devices according to another invention are provided so as to cross the lock arms, and the two lock arms are formed so as to reach the fulcrum through each other's interior. Yes. When configured in this way, compared to a configuration in which the two lock arms are shifted in the front-rear direction in the thickness direction, the force of the wheel trying to force escape does not concentrate on the lock arm on one side, that is, in this configuration The wheel force is applied to the lock arms on both sides, making it difficult to break. Also, since it is a kind of staggered nesting state that enters the internal space of the other party, the length of the front and rear of the device is shorter and smaller than the configuration in which the two lock arms are shifted back and forth in the thickness direction. Can be realized.

  In addition to the configuration of the above-described invention, two wheel lock devices according to another invention are provided so as to cross the lock arms, and when de-outputting works on the lock arms, the wheel lock device is on the side opposite to the fulcrum of the lock arms. It is set as the structure which a front-end | tip part approaches mutually. If this configuration is adopted, illegal forced escape can be prevented or reduced with a simple configuration. Further, it is preferable that the holes provided in the lock arm are provided so as to intersect with each other in an X shape so that the holes are overlapped, and the cam is inserted into the two holes. If this structure is employ | adopted, two lock arms can be driven with one cam, and a structure is simplified.

  Further, it is preferable that when the de-outputting acts on the lock arm, the contact portion between the cam and the lock arm shifts to a separated state. When this configuration is adopted, the lock arm that has been driven by the cam is separated from the cam at the time of forced escape, so that the force of forced escape is not applied to the cam side.

  In addition to the above-described invention, the wheel lock device of another invention is configured so that the lock arm is separated from the transmission member that transmits the driving force of the drive source when the de-outputting acts on the lock arm. According to this configuration, since the transmission member is separated from the lock arm, the force at the time of forced escape applied to the lock arm is not transmitted to the drive source side. For this reason, both the drive source and the transmission member that transmits the force of the drive source to the lock arm are not broken or partly lost during forced escape.

  The parking system according to the present invention includes a wheel rail on which a wheel is mounted, and a wheel lock device according to the present invention described above that locks the wheel mounted on the wheel rail by driving a lock arm with a motor. And energization control means for controlling energization to the motor.

  If this structure is employ | adopted, a lock arm can be opened and closed using a simple motor, and thereby the wheel on the wheel rail can be locked, and illegal forced escape can be prevented or reduced.

  The drive method of the lock arm for parking according to the present invention is a drive method of the lock arm for locking the wheel, wherein the cam is rotated by the rotation of the output shaft of the motor, and the cam is inserted by the displacement accompanying the rotation of the cam. The lock arm having a hole is swung around the fulcrum to generate a locked state of the wheel and an open state of the wheel, and to try to escape the locked wheel from the locked state. The lock arm is rotated in one direction by the de-outputting when it is moved.

  By adopting this method, it is possible to open and close the drive lock arm using a simple motor capable of rotating the output shaft in one direction by energization, and to prevent or reduce forced escape.

  In the present invention, illegal forced escape can be prevented or reduced.

  Hereinafter, a wheel locking device, a parking system, and a driving method of a parking lock arm according to an embodiment of the present invention will be described with reference to the drawings. The wheel lock device will be described as a part of the parking system. A method for driving the lock arm for parking will be described as a part of the operation of the wheel lock device.

  FIG. 1 is a perspective view showing a bicycle parking system according to an embodiment of the present invention.

  The parking system according to this embodiment mainly includes a low rack unit 1, a high rack unit 2, the same number of wheel locking devices 3 as the total number of low rack units 1 and high rack units 2, and a collecting unit 4. Have. In this embodiment, a bicycle parking system having one low rack unit 1 and one high rack unit 2 will be described as an example. However, there are two or more low rack units 1 and two high rack units 2 respectively. Also good. In addition, since this embodiment has one low rack unit 1 and one high rack unit 2, there are two vehicle locking devices 3.

  The low rack unit 1 includes a low rail wheel rail 21, a guide member 22, and a roller 23.

  The low-rack wheel rail 21 has a bottom portion 21a and two side portions 21b and 21b. The width of the bottom portion 21a is formed wider than the width of the bicycle wheel 101, and the length of the bottom portion 21a is formed in a long shape that is substantially the same as the length of the bicycle. In addition, the length of the bottom 21a may be formed in a long shape to the extent that a front wheel or a rear wheel of the bicycle is placed. The two side portions 21b and 21b are respectively provided in a shape that stands along the long end of the bottom portion 21a and substantially perpendicular to the bottom portion 21a. Thereby, the wheel rail 21 for low racks is formed in a substantially U-shaped cross section. Such a low-rack wheel rail 21 can be formed by bending a long steel plate at both ends in the short direction to the same side.

  The low rack wheel rail 21 is fixed to the rear frame 5 at one end in the longitudinal direction. Further, the other end side of the low-rack wheel rail 21 in the longitudinal direction is fixed to the front frame 6 with the wheel lock device 3 interposed therebetween. Thereby, the wheel rail 21 for low racks is fixed to the inclined posture in which the other end side is lifted rather than the one end side in the longitudinal direction. Hereinafter, the other end side where the low-rack wheel rail 21 is lifted is referred to as a front end of the low-rack wheel rail 21, and this one end side is referred to as a rear end.

  The guide member 22 of the low rack unit 1 is provided so as to follow the shape of the wheel rail 21 for low rack and to protrude upward from the wheel rail 21. The guide member 22 of the low rack unit 1 is configured such that the height from the low rack wheel rail 21 to the upper edge of the guide member 22 is the same as or slightly lower than the radius of the bicycle wheel. Is formed.

  The roller 23 of the low rack unit 1 has a rotating shaft attached between two side portions 21b and 21b of the wheel rail 21 for the low rack via a pedal 71 which will be described later. It is rotatably arranged in the longitudinal direction of 21a. The roller 23 is disposed at the center of the low rack wheel rail 21 in the longitudinal direction or at a position slightly closer to the tip of the wheel rail 21 than the center. The roller 23 is attached in a shape protruding upward from the bottom 21a. The bottom 21a on the tip side of the roller 23 is formed to be horizontal with respect to the ground, and the bottom 21a is an inclined surface that gradually increases in height from the rear end of the wheel rail 21 to immediately before the roller 23. Is formed.

  A bicycle is pushed into the low rack unit 1 from the rear end side of the low-rack wheel rail 21 that is lowered. When the front wheel of the bicycle exceeds the roller 23, the bicycle does not return to the rear end side even if the hand is released from the bicycle, and the bicycle is supported while standing against the guide member 22. . Thereby, the bicycle can be parked while standing in the low rack unit 1.

  The high rack unit 2 includes a high rail wheel rail 31, a guide member 32, and a roller 33.

  The wheel rail 31 for high racks has a bottom part 31a and two side parts 31b and 31b. Moreover, the wheel rail 31 for high racks has a shape in which the wheel rail 21 for low racks is further lengthened and bent at a steep angle at the center in the longitudinal direction.

  The wheel rails 31 for the high rack are fixed to the rear frame 5 with one end side in the longitudinal direction sandwiching the lower support column 7 or directly. Further, the other end side in the longitudinal direction of the wheel rail 31 for the high rack is fixed to the front frame 6 with the wheel lock device 3 and the high column 8 interposed therebetween. Thereby, the wheel rail 31 for high racks is fixed to the largely inclined posture in which the other end side is lifted rather than the one end side in the longitudinal direction. Hereinafter, the other end side where the wheel rail 31 for high racks is lifted is described as the front end of the wheel rail 31 for high racks, and this one end side is described as the rear end.

  The guide member 32 of the high rack unit 2 has the same shape as the guide member 22 of the low rack unit 1 and is provided so as to follow the shape of the wheel rail 31 for the high rack and to protrude above the wheel rail 31. It is what The guide member 32 of the high rack unit 2 is such that the height from the high rack wheel rail 31 to the upper edge of the guide member 32 is the same as or slightly lower than the radius of the bicycle wheel. Is formed.

  The roller 33 of the high rack unit 2 has the same configuration as the roller 23, and is rotatable between two side portions 31b and 31b of the wheel rail 31 for the high rack via a pedal 71 described later, and It is arranged so as to have the same positional relationship as the roller 23. The reason why the rollers 23 and 33 are attached to the pedal 71 described later is to prevent unauthorized parking. That is, when the rollers 23 and 33 are directly attached to the side portions 21b, 21b, 31b and 31b, the bicycle is supported by the guide member 22 and the roller 23 or by the guide member 32 and the roller 33, and the pedal 71 is lowered. It becomes easy to cause a state where there is no illegal parking. However, if the rollers 23 and 33 are attached to the pedal 71, when the rollers 23 and 33 are pushed, the pedal 71 is also pushed reliably, and parking can be detected. Further, the roller 33 is closer to the tip than the bent portion of the wheel rail 31 for the high rack, and the position in the longitudinal direction of the wheel rail 31 for the high rack or slightly closer to the tip of the vehicle rail 31 than the center. It is arranged.

  A bicycle is pushed into the high rack unit 2 from the rear end side of the lower high-rack wheel rail 31. Then, when the bicycle is pushed in until the front wheel of the bicycle gradually rises up the bottom 31a on the rear end side where the bicycle has a steep angle and the front wheel of the bicycle exceeds the roller 33, the bottom 31a of the front wheel of the bicycle is horizontal. And the roller 33 prevents the returning operation. For this reason, even if the hand is released from the bicycle, the bicycle is not pushed back, and the bicycle is supported while standing against the guide member 32. As a result, the bicycle can be parked while standing on the high rack unit 2.

The lock arm 53 and the lock arm 54 are arranged and used in pairs. The lock arm 53 and the lock arm 54 are each formed in a substantially half-ring shape (hereinafter referred to as a semi-annular shape). The lock arm 53 and the lock arm 54 are installed so as to cross in an X shape (see FIG. 6). When both the lock arms 53 and 54 face each other and the tips thereof are brought into contact with each other, a substantially ring having a diameter of the distance between the contact portion and the eccentric cam 61 is formed. These lock arms 53 and 54 are formed of metal members. However, it may be formed of a polycarbonate resin. Polycarbonate resin is a kind of engineering plastic and has a characteristic that it is not easily damaged even when a large force is applied. In addition, engineering plastics such as polycarbonate resin have a feature that the material is softer than metal, so that it is difficult to damage the bicycle even if it hits the bicycle. For this reason, engineering plastics other than polycarbonate resin or other hard resin materials may be used for the lock arms 53 and 54.

  The lock arms 53 and 54 have exactly the same shape and can be used interchangeably. The lock arm 53 includes a central lock plate 53a and two side plates 53b and 53b which are arranged on both sides of the lock plate 53a and fixed to the lock plate 53a.

Similarly, fulcrum holes 54c and 54c are provided in the side plates 54b and 54b, and the support shaft 51 is inserted therein. The lock arm 53 rotates and swings about the support shaft 52 for the fulcrum, and the lock arm 54 rotates and swings about the support shaft 51 for the fulcrum. In addition, each rotation fulcrum becomes a central axis of the support shafts 51 and 52.

  Long holes 53d and 53d are provided in the approximate center of the side plates 53b and 53b, and long holes 54d and 54d are also provided in the approximate center of the side plates 54b and 54b. An eccentric cam 61 to be described later is inserted into the long hole 53d on the distal end of the long holes 53d and 53d and the long hole 54d on the distal end side of the long holes 54d and 54d.

  The lock arms 53 and 54 are configured such that when the wheel 101 is forced to escape, the gap G between the other ends is further narrowed. That is, the support shafts 51 and 52 that serve as the pivotal fulcrum of the lock arms 53 and 54, the position of the upper end of the lock arm that serves as the action point, and the direction of the force applied when the parked vehicle tries to escape. Devised a relationship with. Details of this point will be described when the operation of the bicycle parking system is described.

  The eccentric cam 61 is rotationally driven by a motor 62 serving as a drive source and a speed reduction unit 63, and these constitute a drive unit. The drive unit is fixed to the vertical portion 48 a of the frame component 48 and is disposed in the internal space of the frame component 48. This fixing is performed by inserting an elastic member made of a cylindrical rubber material into the three holes 48f of the vertical portion 48a so that the inside and both ends of the hole 48f protrude and pass through the center of the cylindrical elastic member. This is done by inserting a screw. In this way, by attaching the motor 62 and the speed reduction unit 63 to the vertical portion 48a serving as the chassis via the elastic member, it is possible to transmit power without using a shaft coupling. As described above, since the fixing is performed through the elastic member, even if the output shaft 63b of the speed reduction unit 63 and the support portion 61b on the rear end side of the eccentric cam 61 are displaced or both or one of them is inclined. It is possible to absorb errors and the like caused thereby.

  As shown in FIGS. 4 and 5, the eccentric cam 61 includes a support portion 61a on the front end side, a support portion 61b on the rear end side arranged in a straight line with the support portion 61a, and both support portions 61a and 61b. On the other hand, it has a columnar cam portion 61c whose center is eccentric, and a columnar engagement recess 61d into which the output shaft 63b of the speed reduction unit 63 is inserted. The engagement portion recess 61d is formed on the end side of the support portion 61b, and a screw for integrating the output shaft 63b and the eccentric cam 61 is inserted into a portion surrounding the engagement recess 61d. The screw hole is formed perpendicular to the axial direction.

  The motor 62 includes a cylindrical motor housing 62a, an output shaft 62b rotatably supported by the motor housing 62a, a rotor (not shown) fixed to the output shaft 62b, and the rotor and the motor housing 62a. And a stator (not shown) disposed. When a magnetic field is generated in the rotor and / or the stator by energization, the rotor and the output shaft 62b are rotated by a magnetic attractive force or a repulsive force between the stator magnetic field and the rotor magnetic field. When energization is lost, the rotation of the rotor and output shaft 62b stops.

  The reduction unit 63 has a gear group (not shown) in the unit case 63a and a reduction output shaft 63b. The gear group includes a plurality of gears, and includes at least a gear that rotates together with the output shaft 62b of the motor 62 and a gear that rotates together with the reduction output shaft 63b. And the deceleration rate by this deceleration unit 63 should just be about 1/1000-1/50. For example, when the deceleration rate is 1/100, the output shaft 62b of the motor 62 rotates 100 times, so that the deceleration output shaft 63b rotates once. In addition, it can replace with a gear group and can make it obtain a desired deceleration rate with the pulley group comprised by a some pulley. However, when a pulley is used, it is preferable to use a gear group because slippage is inevitably generated between the pulley and the belt that spans the pulley.

  When the deceleration output shaft 63b rotates, the eccentric cam 61 rotates around the support portions 61a and 61b. Further, along with this rotation, the outermost portion of the cam portion 61c of the eccentric cam 61 and the portion farthest from the center of rotation is located in the long holes 53d and 54d of the lock arms 53 and 54 of the support portions 61a and 61b. Rotates in a plane perpendicular to the central axis. The moving range in which the eccentric cam 61 moves up and down is set such that the distance between the center axis of the support portions 61a and 61b and the outer peripheral portion farthest from the rotation center is x, the center axis of the support portions 61a and 61b, and the rotation center If the distance from the nearest outer peripheral portion to y is y, xy corresponds to it. The greater the xy, the wider the range of movement that moves up and down.

  A detection plate 64 is fixed to the support 61b on the rear end side of the eccentric cam 61 by screws. The front end of the detection plate 64 is bent toward the motor 62, and the front end portion is detected by sensors 65 and 66 described later.

  The drive unit is fixed to the frame member 45 so that the rotation center of the eccentric cam 61 and the center axis of the deceleration output shaft 63b are aligned. As a result, when the eccentric cam 61 rotates about the support portions 61 a and 61 b, the lock arms 53 and 54 are predetermined about the support shafts 51 and 52 according to the movement accompanying the rotation of the cam portion 61 c of the eccentric cam 61. Oscillates within the angular range.

  Note that the angle range of the rocking of the lock arms 53 and 54 is determined according to the size of the cam portion 61c of the eccentric cam 61 and the like. That is, as the difference between the distance x and the distance y, which is the degree of eccentricity in the cam portion 61c, is increased, the angular range of rocking of the lock arms 53 and 54 can be expanded. In this embodiment, when the outer peripheral portion of the cam portion 61c of the eccentric cam 61 is at the lowest position, both the lock arms 53, 54 are opened, that is, both the lock arms 53, 54 becomes an open state. At this time, the interval G between the other end portions (= upper end) of the lock arms 53 and 54 becomes the largest and becomes the interval G1.

  As shown in FIG. 7, the position where the eccentric cam 61 rotates approximately 180 degrees from the state shown in FIG. 6 is the state where both lock arms 53 and 54 are closest, that is, both the lock arms 53 and 54 are closed. Become. At this time, the interval G between the other end portions (= upper end) of the lock arms 53 and 54 is the smallest and becomes the interval G2.

  Thereby, the lock arm 53 and the lock arm 54 can be opened and closed by rotating the motor 62 of the drive unit by energization. Note that the other end of the lock arm 53 and the other end of the lock arm 54 do not have to be in strict contact with each other when the lock arm 53 is most closed. It is only necessary that the distance between the other end of the lock arm 53 and the other end of the lock arm 54 when closed most is narrower than the width of the bicycle wheel.

  Further, a closed position detection sensor 65 and an open position detection sensor 66 are disposed in the internal space of the frame constituent member 47 together with the sensor substrate 67. The sensor substrate 67 is fixed to the frame constituent member 48. The closed position detection sensor 65 and the open position detection sensor 66 are optical sensors that optically detect the position of the detection plate 64. The optical sensor has a light emitting element and a light receiving element, and is a sensor that detects a change in a light receiving state in the light receiving element of light from the light emitting element. In addition, there are two types of optical sensors, a reflective type and a transmissive type, depending on the relative positions of the light emitting element and the light receiving element, and either type may be adopted.

  For example, when a transmissive optical sensor is used as the closed position detection sensor 65, the other end of the lock arm 53 and the other end of the lock arm 54 are in contact with or close to each other, that is, the cam portion 61 c of the eccentric cam 61. The closed position detection sensor 65 is arranged so that the detection plate 64 that rotates integrally with the eccentric cam 61 when the outer peripheral portion is at the highest position is positioned between the light emitting element and the light receiving element of the closed position detection sensor 65. . When the other end of the lock arm 53 and the other end of the lock arm 54 are separated, the detection plate 64 is not positioned between the light emitting element and the light receiving element of the closed position detection sensor 65. It is necessary to install. The closed position detection sensor 65 outputs a detection signal when the light receiving element stops receiving light.

  When a transmissive optical sensor is used as the open position detection sensor 66, the state where the other end of the lock arm 53 is farthest from the other end of the lock arm 54, that is, the outer peripheral portion of the cam portion 61c of the eccentric cam 61 is The open position detection sensor 66 is arranged so that the detection plate 64 is positioned between the light emitting element and the light receiving element of the open position detection sensor 66 when the lowest position is reached. When the other end of the lock arm 53 and the other end of the lock arm 54 are not farthest apart, the open position is set so that the detection plate 64 is not located between the light emitting element and the light receiving element. It is necessary to install the detection sensor 66. The open position detection sensor 66 outputs a detection signal when the light receiving element stops receiving light.

  The wheel lock device 3 has a pedal 71. As shown in FIGS. 2 and 5, the pedal 71 includes a substantially rectangular pedal body 71 a and a pedal link plate 71 b disposed at one end of the pedal body 71 a in the longitudinal direction. The pedal body 71a rotates at the other end in the longitudinal direction around a fixed shaft 71c disposed between the two side surfaces 21b and 21b of the wheel rail 21 and the two side surfaces 31b and 31b of the wheel rail 31. It is installed as possible. Thereby, the pedal 71 can rotate centering on one end thereof. The pedal link plate 71b is provided with a link portion 71d protruding to the rear end side. The link portion 71d is engaged with the one end portion 73a side of the detection shaft 73, and the detection shaft 73 is rotated in accordance with the vertical movement of the pedal 71.

  The pedal link plate 71b penetrates through the through-hole 75 (see FIG. 5) formed in the wheel rails 21, 31 in a state where the pedal body 71a is disposed on the wheel rails 21, 31, so that the wheel rails 21, It protrudes to the back side of 31. And as mentioned above, the link part 71d is formed in the front-end | tip part which protrudes to the back side of 21 and 31 of the pedal link board 71b. A winding spring 74 as an urging member is disposed at one end 73 a of the detection shaft 73. Therefore, for example, when the pedal body 71a is pushed down by the load of the wheel 101 from a state where one end of the pedal body 71a is lifted, the one end 73a side of the detection shaft 73 is also pushed down. The detection shaft 73 is rotated by the pressing force, and the detection plate 72 is also rotated with this rotation.

  The detection plate 72 includes a detection plate main body 72a formed in a substantially rectangular shape, and a sensor plate portion 72b that is bent toward the motor 62 side at the front end side of the detection plate main body 72a. The detection plate main body 72a is fixed to the detection shaft 73 at one end in the longitudinal direction. The detection shaft 73 is composed of a single shaft member, and has one end portion 73a that engages with the link portion 71d, and a support portion 73b around which the winding spring 74 is wound and supported by the frame member 45. The one end 73a is orthogonal to the length direction of the wheel rails 21 and 31, and is arranged in a substantially horizontal direction. The support portion 73b is arranged in parallel to the length direction of the wheel rails 21 and 31.

  The winding spring 74 has a coil part 74a and a pair of hook parts 74b formed at both ends of the coil part 74a. One hook portion 74 b of the pair of hook portions 74 b is hung on the engaging portion 73 a of the detection shaft 73. The other hook part 74 b in the pair of hook parts 74 b is suspended in a hole 46 r provided in the frame component member 46. As a result, a force in the direction of lifting the pedal 71 is biased to the detection shaft 73. Further, when the bicycle is not riding on the pedal 71 due to the urging force of the winding spring 74, one end of the pedal body 71a attached to the wheel rails 21, 31 is lifted from the wheel rails 21, 31 ( (See FIG. 5).

  In order to detect the position of the detection plate 72, a press detection sensor 75 as a parking detection sensor is provided. The position of the sensor plate portion 72b in a state where one end of the pedal body 71a is in contact with or close to the wheel rails 21, 31 is detected. As the press detection sensor 75, for example, a transmission type optical sensor may be used. The press detection sensor 75 outputs a detection signal when the light receiving element of the transmissive optical sensor receives light. In this embodiment, the press detection sensor 75 is disposed on the sensor substrate 67 together with the closed position detection sensor 65 and the open position detection sensor 66. In addition, the sensor substrate 67 is fixed to the frame constituent member 48 described above, and is disposed in a space surrounded by the frame constituent member 47, and in a direction perpendicular to the surface of the upper surface portion 41a of the housing 41. It is arranged.

  FIG. 8 is a block diagram showing a control system of the collecting unit 4 and the parking system in FIG. FIG. 9 is a view showing a state in which the bicycle wheel 101 is placed on the wheel rails 21 and 31. FIG. 10 is a diagram showing an initial state of the wheel lock device when it is going to be forced escape, and is a diagram showing a part seen through from the front end side, and FIG. 11 is a diagram when it is going to be forced escape It is a figure which shows the state of the wheel locking device after force is added, and is a figure shown in the state which saw through partially from the front end side.

  The collecting unit 4 includes a timer 81 that outputs time information, a recording unit 82 that stores data, an input key 83, a display unit 84, a fee collection unit 85 into which bills and money are inserted, and the vehicle lock device 3. A motor drive unit 86 for energizing the motor 62 and a microcomputer. By executing a parking control program (not shown), the microcomputer performs a parking detection unit 91, a lock control unit 92 as an energization control unit, a fee calculation unit 93, a deposit metering unit 94, and an energization control unit. The unlocking control unit 95 is realized. The parking control program can be stored in the recording unit 82 using a computer-readable recording medium such as a compact disk (not shown) or a transmission medium such as an electric communication line as a medium.

  When a detection signal is input from the press detection sensor 75, the parking detection unit 91 reads time information at the input timing of the detection signal from the timer 81, and causes the recording unit 82 to record the read time information as a parking start time. Is.

  The lock control unit 92 causes the motor drive unit 86 to start energization after the detection signal is input to the parking detection unit 91. In addition, when the detection signal is input from the closed position detection sensor 65, the locking control unit 92 stops energization by the motor driving unit 86.

  The period from when the detection signal is input to the parking detection unit 91 until the locking control unit 92 starts energization of the motor drive unit 86 can be set to an arbitrary time. That is, as soon as a detection signal is input to the parking detection unit 91, the locking control unit 92 may be set to start energization of the motor drive unit 86. For example, after the detection signal is input to the parking detection unit 91, 20 The locking control unit 92 may be set to start energization of the motor driving unit 86 after a predetermined time such as minutes elapses.

  When the low rack unit 1 or the high rack unit 2 to be cleared is specified by, for example, a unique identification number for each rack unit, the charge calculation unit 93 starts parking of the rack unit from the recording unit 82. In addition to reading the time, the current time information is read from the timer 81, and the charge is calculated based on the time difference therebetween. Further, the fee calculation unit 93 displays the calculated fee on the display unit 84.

  The deposit metering unit 94 calculates a fee input to the fee collection unit 85. Then, the deposit weighing unit 94 notifies the unlocking control unit 95 when the charged fee is equal to or higher than the fee calculated by the fee calculating unit 93.

  The unlock control unit 95 causes the motor drive unit 86 to start energization when notified from the deposit metering unit 94. In addition, when the detection signal from the open position detection sensor 66 is input, the unlocking control unit 95 stops energization by the motor driving unit 86.

  Next, the overall operation of the bicycle parking system according to this embodiment will be described.

  The person who has ridden the bicycle places the bicycle on the wheel rail 21 for low rack, for example (see FIG. 9A). Specifically, the bicycle can be placed on the low rack wheel rail 21 by pushing the bicycle from the lower rear end side of the low rack wheel rail 21 toward the front end side. At this time, since the front wheel of the bicycle gets over the roller 23 provided via the pedal 71 in the middle of the wheel rail 21 for the low rack, the bicycle is held so as not to fall back. Moreover, since the guide member 22 is provided in the wheel rail 21 for low racks, even if the hand is released from the bicycle, the bicycle does not fall down and fall from the wheel rails 21 for low rack. The front wheel of the bicycle parked in the low rack unit 1 is placed on the pedal 71.

  The pedal 71 is pushed down by the placement of the front wheel, that is, the weight of the parked bicycle. When the pedal 71 is pushed down, the link portion 71d pushes down the one end 73a side of the detection shaft 73. Since the detection shaft 73 rotates when the one end 73a side is pressed down, the detection shaft 73 rotates when the pedal 71 is pressed down. The detection plate 72 fixed integrally with the detection shaft 73 rotates together with the detection shaft 73. When the sensor plate portion 72b of the detection plate 72 is removed from between the light emitting element and the light receiving element of the press detection sensor 75, the press detection sensor 75 outputs a detection signal.

  When the detection signal from the press detection sensor 75 is input to the parking detection unit 91, the parking detection unit 91 reads time information at the input timing of the detection signal from the timer 81, and uses the read time information as the parking start time. As shown in FIG.

  Further, the lock control unit 92 causes the motor drive unit 86 to start energizing the motor 62 after the detection signal is input to the parking detection unit 91. The output shaft 62b of the motor 62 starts to rotate by energization by the motor drive unit 86, and the eccentric cam 61 also starts to rotate by the rotation obtained by reducing the rotation of the output shaft 62b. As the eccentric cam 61 rotates, the lock arm 53 and the lock arm 54 rotate in the closing direction. When a detection signal is input from the closed position detection sensor 65, the locking control unit 92 stops energization by the motor drive unit 86.

  In a state where the detection signal from the closed position detection sensor 65 is output, the other end of the lock arm 53 and the other end of the lock arm 54 are in contact with or in close proximity to each other. In addition, an annular ring is formed when the other ends of the lock arms 53 and 54 come into contact with each other or close to each other, so that the annular ring and the rim of the wheel 101 mounted on the pedal 71 are chained with a slight gap. It becomes a connected state. That is, as shown in FIG. 9B, the wheel 101 is wrapped by the lock arm 53 and the lock arm 54. As a result, even if the bicycle is to be pulled out from the low rack unit 1, the bicycle wheel 101 cannot be pulled out because the rim of the bicycle wheel 101 is caught by the lock arm 53 and the lock arm 54. That is, the bicycle is locked to the low rack unit 1.

  However, sometimes there are those who try to escape illegally. The forced escaper tries to pull out the bicycle with great effort. In the conventional wheel lock device, in such a case, this force acts to open the tip of the lock radius, so that the distance between the tips of both lock arms becomes slightly larger. As a result, an illegal forced escape person puts more power, the drive mechanism of the lock arms 53 and 54 and the lock arms 53 and 54 is broken, and the forced escape succeeds. In addition, if there is a backlash or deflection of the parts, the gap G may become an opening width that allows the wheel 101 to slip through only by trying to pull out the bicycle with a little force.

  On the other hand, as shown in FIG. 10, in the wheel lock device 3 of the present embodiment, when the wheel 101 is lifted by trying to force escape (just escape), the lock arm 53 is pushed in the direction indicated by the arrow A. A clockwise moment M1 is received around the support shaft 52 in FIG. This is a direction to strengthen the restraint. This moment M1 is generated by a force MA in the direction of arrow A generated by the wheel 101. That is, the force MA can be decomposed into a force MA1 on a line connecting the center of the support shaft 52, which is a pivotal fulcrum of the lock arm 53, and an action point, and a force MA2 orthogonal to the straight line. This force MA2 produces a clockwise moment M1. Thus, if the shape of the lock arm 53 and the fulcrum of the lock arm 53 are formed so that the component force MA2 acting in the right direction in FIG. 10 is generated with respect to the lock arm 53, the lock arm 53 moves in the closing direction. Will be.

  Similarly, the lock arm 54 is also pushed in the direction indicated by the arrow B, and receives a moment M <b> 2 in a direction that strengthens the restraint around the support shaft 51. This moment M2 is also generated by the force MB in the direction indicated by the arrow B generated by the wheel 101. That is, the force MB can be decomposed into a force on a line connecting the center of the support shaft 51 that is the rotation fulcrum of the lock arm 54 and the action point, and a force orthogonal to the straight line. This orthogonal force generates a counterclockwise moment M2 in FIG. Thus, if the shape of the lock arm 54 and the fulcrum of the lock arm 54 are formed so that a component force acting in the left direction in FIG. 10 is generated with respect to the lock arm 54, the lock arm 54 moves in the closing direction. It will be.

  As a result, even if forced escape (just escape) is attempted, the lock arm 53 and the lock arm 54 are closed (see FIG. 11), so the wheel 101 cannot escape. At this time, the interval G is further narrowed to become the interval G3. In FIGS. 10 and 11, the cam portion 61c of the eccentric cam 61 and the support portions 61a and 61b are shown with hatched lines so that they can be clearly seen.

  When the lock arm 53 and the lock arm 54 are moved in the closing direction, the cam follower portion surrounding the elongated holes 53d and 54d, that is, the contact portion with the eccentric cam 61 is separated from the eccentric cam 61. That is, a space g is formed between the lock arms 53 and 54 and the eccentric cam 61. As a result, since the force of forceful escape is not applied to the motor 62, the eccentric cam 61, the support portions 61a and 61b of the eccentric cam 61, the vertical portion 47b of the frame constituting member 47, etc., the risk of damaging them is greatly reduced.

  Next, the bicycle departure operation will be described. A person who wants to leave the bicycle from the previous low rack unit 1 operates the input key 83 to designate the low rack unit 1. The charge calculation unit 93 reads the parking start time of the low rack unit 1 designated by the input key 83 from the recording unit 82 and reads the current time information from the timer 81. The current time at this time is the parking end time. Then, the fee calculation unit 93 calculates a parking fee based on the time difference between the parking start time and the parking end time, and causes the display unit 84 to display the calculated parking fee.

  A person who wants to leave the bicycle inputs the parking fee displayed on the display unit 84 to the fee collection unit 85. The deposit metering unit 94 notifies the unlocking control unit 95 when the fee input to the fee collection unit 85 exceeds the fee calculated by the fee calculation unit 93. If the input fee exceeds the parking fee, the deposit metering unit 94 may return the difference to the fee collection unit 85.

  The unlocking control unit 95 immediately starts energization of the motor driving unit 86 upon receiving a notification from the deposit weighing unit 94. When the motor drive unit 86 is energized, the output shaft 62b of the motor 62 starts to rotate in the same direction as when locked, and the eccentric cam 61 also starts to rotate by rotating the output shaft 62b decelerated. As the eccentric cam 61 rotates, the lock arm 53 and the lock arm 54 rotate in the opening direction. When the detection signal from the open position detection sensor 66 is input, the unlocking control unit 95 stops energization by the motor driving unit 86.

  In the state where the detection signal is output from the open position detection sensor 66, the other ends of the lock arms 53 and 54 are in the most separated state. Therefore, a person who wants to leave the bicycle can pull out the bicycle from the low rack unit 1.

  The operation of the bicycle parking system when the bicycle is parked in the high rack unit 2 is the same as that when the bicycle is parked in the low rack unit 1 described above, and the description thereof is omitted.

  As described above, in the bicycle parking system according to this embodiment, the bicycle parked in the low rack unit 1 and the high rack unit 2 can be locked and unlocked in accordance with the payment of the parking fee. it can. In addition, the bicycle parking system according to this embodiment can manage the parking of bicycles in the low rack unit 1 and the high rack unit 2.

  In particular, the wheel lock device 3 according to this embodiment includes lock arms 53 and 54 that lock the wheel 101, a motor 62 that rotates the output shaft 62b when energized, an eccentric cam 61 that rotates together with the output shaft 62b, and a lock It has long holes 53d and 54d formed in the arms 53 and 54 and into which the eccentric cam 61 is inserted. Therefore, the wheel lock device 3 according to this embodiment rotates the eccentric cam 61 by the rotation of the output shaft 62b of the motor 62, and the lock arm 53, into which the eccentric cam 61 is inserted by the displacement accompanying the rotation of the eccentric cam 61, 54 can be swung. Therefore, both the lock arms 53 and 54 can be opened and closed by using a simple motor 62 and a simple mechanism that can rotate the output shaft 62b by energization.

  In the wheel lock device 3 according to this embodiment, when the forced escape is attempted, the lock arms 53 and 54 move in the closing direction, so that the forced escape can be prevented. Further, when the forced escape is attempted, the eccentric cam 61 is separated from the lock arms 53 and 54, so that the mechanism that drives the lock arms 53 and 54 can be prevented from being damaged. The motor 62 is a motor that can rotate in both directions. This is for the case where the lock arms 53 and 54 hit the air valve or the like and cannot swing to the end. That is, when the lock arms 53 and 54 are closed, when the lock arms 53 and 54 hit a foreign object such as an air valve or a reflector attached to the spoke, when they hit the wheel 101 placed in a shifted manner, and to the deformed rim. When it hits, the motor 62 rotates to a place where it can go and locks at that position. Thereafter, when the lock arms 53 and 54 are opened, the motor 62 rotates in the reverse direction. By this operation, it becomes possible to cope with a deformed rim or the like. In this way, even if the motor 62 is energized for a predetermined time, even if the closed position detection sensor 65 does not detect it, that is, the lock arms 53 and 54 cannot be fully closed, the other side is not damaged. In addition, an extra load is not applied to the drive source side, and a reliable lock can be obtained.

  In the state where the eccentric cam 61 is in contact with the lock arms 53 and 54 at the upper end of the cylindrical outer peripheral portion and the wheels 101 are locked by the lock arms 53 and 54, as shown in FIGS. The position where the lock arms 53, 54 and the eccentric cam 61 are in contact with the center of rotation of the eccentric cam 61 is located on a substantially straight line. For this reason, when the lock arm 53 and the lock arm 54 are to be opened in a state where the wheels 101 are locked by the lock arms 53 and 54, the force applied to the eccentric cam 61 by the opening force is almost equal to those forces. The force is in the direction from the contact point toward the rotation center of the eccentric cam 61. Therefore, the force applied to the eccentric cam 61 by the force for opening the lock arm 53 and the lock arm 54 hardly generates a component force in the direction in which the eccentric cam 61 is rotated. Moreover, since the lock arms 53 and 54 move in opposite directions, the rotational forces acting on the eccentric cam 61 are also in opposite directions. As a result, in a state where the wheels 101 are locked by the lock arms 53, 54, the eccentric cam 61 is difficult to rotate even if the lock arms 53, 54 are opened, so that the wheels 101 are locked by the lock arms 53, 54. The state can be maintained.

  In addition, the wheel lock device 3 according to this embodiment includes a deceleration unit 63 that decelerates between the output shaft 62b and the eccentric cam 61 so that the rotational speed of the eccentric cam 61 is lower than the rotational speed of the output shaft 62b. Is provided. Therefore, the force for rotating the eccentric cam 61 is increased by the speed reduction unit 63 and acts on the output shaft 62 b of the motor 62. Accordingly, the resistance force of the cogging torque acting between the rotor and the stator becomes extremely large, and even when the motor 62 is not energized, even if force is applied in the direction of opening both the lock arms 53 and 54. Both lock arms 53 and 54 hardly move. For this reason, the force transmitted to the eccentric cam 61 is also reduced, and the eccentric cam 61 is difficult to rotate. As a result, the locked state of the wheel 101 by the lock arm 53 and the lock arm 54 can be maintained while using a small motor 62 having a low output.

  In the wheel lock device 3 according to this embodiment, the lock arm 54 and the lock arm 53 swing in the reverse direction. As a result, it is possible to ensure an opening angle that is approximately twice that of a case where only the lock arm 53 is swung and opened. Conversely, for example, even if the eccentric cam 61 is reduced in diameter and the angle at which the lock arms 53 and 54 are swung is substantially halved, the same opening angle as that when only one of the lock arms 53 and 54 is swung open is used. Can be secured. Thereby, the wheel locking device 3 can be reduced in size and weight.

  The wheel lock device 3 according to this embodiment includes a pedal 71 that is pushed down by a parked wheel 101, a detection plate 72 that is displaced when the pedal 71 is pushed down, and a detection plate 72 that is in a state where the pedal 71 is pushed down. A press detection sensor 75 to detect, and a winding spring 74 in which the detection plate 72 urges a force in the direction of the position of the press detection sensor 75. For this reason, it can be detected by the press detection sensor 75 that the pedal 71 is depressed, that is, that the vehicle wheel 101 is in a correct position where it can be locked. Then, the motor 62 can be controlled based on the detection signal of the press detection sensor 75 to lock the wheel 101. Further, the detection shaft 73 is rotated and the detection plate 72 is rotated with a simple configuration in which the other end of the winding spring 74 is hooked into a hole 46 r provided in the frame component member 46.

For example, in the above-described embodiment, the motor 62 that rotates in both directions, that is, the motor 62 that rotates to the position where the eccentric cam 61 can go, locks in that position, and then rotates in the reverse direction is used. By using a rotating motor, or by providing a protruding portion on a part of the outer periphery of the deceleration output shaft 63b or the eccentric cam 61, the protruding portion hits the abutting portion disposed on the frame member 45 or the like. It is good also as a bi-directional rotation motor which stops rotation and rotates in the reverse direction after that.

  In the above-described embodiment, the wheel lock device 3 locks the wheel 101 by sandwiching the wheel 101 with the lock arms 53 and 54, but hooks the wheel 101 with only one of the lock arms 53 and 54. The wheel 101 may be locked. Further, although the lock arms 53 and 54 are swung by the rotation of the eccentric cam 61, the rotation may be rotated by using a solenoid mechanism as in the related art instead of the motor 62. Alternatively, the lock arms 53 and 54 may be rotated by the weight and movement of the wheel 101 and fixed by a solenoid mechanism. Further, each of the lock arms 53 and 54 may be swung by a solenoid mechanism. Moreover, it is good also as a cam of another shape instead of an eccentric cam. Furthermore, the hole into which the cam is inserted may not be the long holes 53d and 54d, but may be a notch hole with one side opened.

  Further, the lock arms 53, 54 are arranged such that the front end side plate 53b is arranged at the most distal end, then the front end side plate 54b is arranged, and then the rear end side plate 53b is arranged, and Although the rear side plate 54b is arranged at the most rear end side, the lock arms 53 and 54 may be arranged in another relationship. For example, the front side plate 54b of the lock arm 54 may be the most distal side. In addition, the lock arms 53 and 54 can be variously modified, such as a single member or a C-shaped shape.

  In the above-described embodiment, the wheel lock device 3 is disposed on the lower side of the wheel 101.
