Description

Specification

Steering block device technical field

This invention relates to a locking device, especially a steering lock device that has great resistance to breaking. Background art

A conventional cylinder lock device has a key cylinder provided with a tumbler that engages a groove formed in a case. It can rotate to the mouth position. The conventional steering lock device, in which the key cylinder is prevented from rotating by the tumbler that engages the groove in the case, can damage the tumbler. There is a risk of unauthorized unlocking. Thus, for example, as disclosed in Japanese Patent Application Publication No. Hei 11-315569, when a key cylinder is subjected to an unauthorized unlocking operation in which a rotational force is applied to the key cylinder, the key cylinder is unlocked. -A free-standing cylinder lock that allows the cylinder to rotate freely has been proposed. The cylinder lock includes a sleeve rotatably arranged in a case, and a key cylinder rotatably supported in the sleeve. ing.

When a regular key is inserted into the key cylinder, the evening bracket in the key cylinder separates from the groove formed in the sleeve and the key cylinder is removed. You can rotate the underlayer relative to the sleeve. This allows the sliding ring to engage the mouthpiece actuating member to operate the mouthpiece device. Also, when a different kind of key is inserted into the key cylinder, the key cylinder is held in a state of being engaged with the sleeve by the tumbler. The key cylinder rotates with the sleeve. As a result, the lock piece operating member cannot be rotated, so that the mouthpiece device cannot be operated.

In such a free-in-one type cylinder lock, when a different type of key is used, the key cylinder rotates freely. Tumbler destroyed for this Since it is not possible to apply a large amount of rotational force, it is possible to provide a great resistance to destruction.

At this point, the locking device disclosed in Japanese Patent Application Laid-Open No. 11-35569 cannot be applied to a steering lock device. Further technology development is required when applying the free evening cylinder lock to a steering lock device.

Therefore, the present invention solves the above-mentioned drawbacks and provides a steering lock device in which the key cylinder can be completely freely rotated at the time of unauthorized unlocking. This is the purpose. Disclosure of the Invention · A steering lock device according to the present invention includes a frame, a sleeve rotatably arranged in the frame, and a sleeve. A key cylinder rotatably arranged in the sleeve, and a key cylinder slidably arranged in the key cylinder and capable of engaging with the locking portion of the sleeve. And a first port which is rotatably and axially movable with respect to the sleeve and which is connected to the cylinder with a cam. It has an evening and a second mouth that is operatively connected to the rocking road and the ignition switch. When the key cylinder is rotated relative to the sleeve, the first row moves in the axial direction and is connected to the second mouth. After that, the cylinder, the first row evening and the second row evening are rotated together, and the locking road is unlocked from the lock position. It is moved to the lock position.

A sleeve holding device is provided to prevent the sleeve from rotating, and when the key cylinder is rotated while the evening and the sleeve are engaged. The sleeve rotates against the elasticity of the sleeve holding device. In addition, the sleeve is rotatably arranged in the nozing arranged in the frame. A low evening spring is located between the first low evening and the second low evening. A connector is placed between the first evening and the second evening. The connector is connected to the second port when the first row rotates with the sleeve. The rotation of the first rotor is prevented, and after the first rotor is moved in the axial direction, the rotor is rotated together with the first rotor and the second rotor. After rotating the key cylinder relative to the sleeve at a fixed angle, if the key cylinder is further rotated, the first loader is further rotated. Moved in the axial direction.

A check lever is positioned within the frame so that it can rotate around the bin outside the sleeve. One end of the check lever is abutted on a dog that slides radially when the key is inserted into the key cylinder, and the check lever The other end is operatively connected to the chuck lever holding device. The check lever holding device has a delay device that holds the locking rod in the lock position until the key is removed from the key cylinder. The delay device is a cylinder operatively connected to the key cylinder, and slidably disposed within the opening of the cylinder and operatively connected to the inside end of the check lever. The first locking member thus formed, a return spring that presses the first locking member in the radial direction, and a projection that can be engaged with the frame. A second locking member slidable in parallel with the first locking member, and pressing the second locking member in a radial direction opposite to the first locking member. And an auxiliary spring. When the first locking member is pressed by the inner end of the check lever, the projection of the second locking member is locked to the frame. It is.

The frame has an intermediate frame and a rear frame, and articulation is possible between the intermediate frame and the rear frame.

Before inserting the regular key into the key cylinder, the key cylinder was connected to the sleeve by the evening brake. The sleeve is held at a predetermined position by a sleeve holding device. The first row at separation position is disengaged from the second mouth.

When a regular key is inserted into the key cylinder, the tumbler is moved away from the sleeve and the key cylinder and sleeve ス: Is disengaged. When the key is rotated in this state, the first mouth is moved from the disengaged position to the engaged position due to the relative rotation of the key cylinder with respect to the sleeve. In the engagement position, the first port is engaged with the second row at the engagement position. After that, when the key cylinder is further rotated, the key cylinder rotates with the first low evening and the second low evening, and the mouth ring is rotated. Move the lock port from the lock position to the unlock position.

When a different kind of key is inserted into the key cylinder, the key cylinder is held in a state of being engaged with the sleeve by the tumbler. When the key is rotated in this state, the key cylinder rotates together with the sleeve. As a result, the relative rotation between the key cylinder and the sleeve does not occur, so that the first row is moved in the axial direction and the second row is moved. Does not engage with. For this reason, it is not possible to move the opening lock port of the steering lock device to the unlock position.

When the key cylinder is rotated from the on position to the lock position, the projection of the second locking member of the delay device is locked to the frame. As a result, the key cylinder is returned to the lock position, but the locking rod does not move to the lock position. When the key is removed from the key cylinder, the check lever rotates to engage the inner end of the check lever with the first locking member. Is released. Therefore, the engagement between the second locking member and the frame is released. This causes the elasticity of the load spring to move the locking rod to the lock position, and the delay device to return to its initial position. It is done.

Articulation is possible between the middle frame and the rear frame, and as the steering shaft tilt angle changes, the middle frame and the rear frame can be moved. The angle with the rear frame can be changed. Brief description of the drawing

One end of the pole spring 36 abuts the front frame 1 la and the other end of the pole spring 36 sleeps the pole 37 Press into the V groove 1 3 c of 13. Therefore, the sleeve 13 is held at the position shown in Fig. 16 by the pressing force of the pole spring 36, but as shown in Fig. 17 When the key cylinder 14 is rotated in the engagement state in which the evening blade 15 projects into the groove 13 a of the sleeve 13, the key cylinder is rotated. The cylinder 14 rotates together with the sleeve 13 against the elasticity of the ball spring 36.

In the above configuration, the connector shaft 26 is normally in the normal state shown in FIG. In this state, when the key cylinder 14 is rotated by the key, the second rotor 18 and the connector shaft 26 are rotated to close the mouth. The king road 32 can be rotated to the unlock position or the lock position.

As shown in FIG. 2, a dog 40 is slidably disposed in a hole 14 d formed in the radial direction of the cylinder 14. The inner end of the dog 40 protrudes into the key groove 14 e of the key cylinder 14, and the outer end of the dog 40 is a checkerboard, * — 41 It is in contact with the bent end 4 la. The checkerboard, '141, is arranged so as to be swingable within the front frame 1 la by the pin 4lc. Check Leno, * 4 4 lb inner end of Check Leno It is possible to make contact with the location 42.

The check and hold device 42 has a delay device 50 mounted outside the connector 25 as shown in FIGS. 29 and 84. You. The delay device 60 includes a connecting rod 61 extending in parallel with the connector 25, a cylindrical portion 62 connected to the connecting rod 61, and an opening of the cylindrical portion 62. A first locking member 43 disposed in the inside of the 2a, a return spring 44 for pressing the first locking member 43 outward, and a first engagement member. A second locking member 45, which is slidable by engaging with the stopping member 43, is disposed between the outer projection 43a of the first locking member 43 and the second locking member 45. Auxiliary springs 46 are provided. The first locking member 43 has an inclined surface 43 c that can abut the inner end 4 lb of the check lever 41. A notch for fitting the protrusion 43 a of the first locking member 43 to the second locking member 45 to determine the movement stroke of the second locking member 45. 45 a and a projection 45 b capable of contacting the abutment surface 1 lc of the intermediate frame 1 lb are provided. As shown in FIG. 29, the cylindrical portion 62 has a cam groove 62b formed on the outer peripheral surface, a fan-shaped concave portion 62c formed at the front end, and a rear end formed at the rear end. It is provided with a cylindrical projection 62d. The cam groove 6 2b is fitted with a 1 lb inner frame projection 19, and the fan-shaped recess 62c is fitted with the second row 18 key 18a. Are fitted. When the cylindrical portion 62 is rotated by the rotation of the second row 18, the cam groove 6 2 b is inserted into the inner projection 1 9 of the intermediate frame 1 lb. When the inclined surface is in contact, the cylindrical portion 62 moves in the axial direction while rotating. The connecting rod 61 is connected to the cylindrical projection 62d.

As shown in FIGS. 85 to 87, when the key cylinder 14 is rotated by an angle of 30 ° by the key, the first locking member 4 3 Project into an arc-shaped groove 47 formed in 1 lb of the middle frame. The key cylinder 14 is 30 ° to 46.3. When rotated, the state shown in FIGS. 65 to 67 is obtained. Further, when the rotation is made to 55 °, the state shown in FIGS. 91 to 93 is obtained. In this state, the inner end 41b of the check lever 41 abuts on the first locking member 43 and is laid. Therefore, in addition, the key cylinder 1 When the lever 4 is rotated, the first locking member 4 3 is resilient to the return spring 4 4 by the inner end 4 lb of the check lever 41. It is moved radially inward in opposition. When rotated to 85 °, the state shown in FIG. 94 to FIG. 96 is obtained, and the protrusion 45 b of the second locking member 45 becomes the elasticity of the auxiliary spring 46. As a result, it protrudes into an arc-shaped groove 47 formed in 1 lb of the intermediate frame. When rotated to 105, the state shown in FIGS. 97 to 99 is obtained. When the key cylinder 14 is returned to 90 ° from this state, the state shown in FIGS. 94 to 96 is obtained, and the first locking member 43 is connected to the chain. Since it is pressed by the inner end 4 lb of the cleno, '41, it cannot protrude into the arc-shaped groove 47. After rotating the key cylinder 14 to the lock position, remove the key from the key cylinder 14 and the dog 40 will turn the key on the key cylinder 14 Since it protrudes into the groove 14e, rotate the pin 41c around the center in the counterclockwise direction until the state shown in Fig. 2 is reached. For this reason, the first locking member 43 moves outward by the elasticity of the return spring 44.

As shown in FIGS. 1 and 26, the front frame 1 la is provided with a pin 45 protruding in the radial direction. The bin 45 is urged outward by a leaf spring 46. Further, on the inner wall of the intermediate frame lib, there is provided a 'projection portion 49 having an inclined surface 47 and a contact surface 48. After pre-assembling parts such as housing 12, sleeve 13 and key cylinder 14 in front frame 1 la, front frame When 1 la is inserted into 1 lb of the middle frame, the pin 45 rides over the protrusion 49 along the inclined surface 47 and engages with the contact surface 48. Will be stopped. When a pin is inserted into the through hole 50 formed in the intermediate frame lib, the pin 45 is pressed inward to release the engagement with the protrusion 49. And can be done.

In the above configuration, when the key is not inserted into the steering lock device 10, the knowing 12, the key cylinder 14, and the second The rotor 18 is in the locked state shown in FIG. In the locked state, as shown in FIG. 18, the driven portion 22 is disposed in the first concave portion 12b. The first rotor 16, connector 17, and second rotor 18 are shown in Figure 19. It is at the lock position shown. The connector section 26, the arm section 63, the comb section 26f and the connector 30 of the connector section 26 are shown in FIG. 106 to FIG. It is in the position shown in Figure 8.

When the regular key 40 is inserted into the key cylinder 14, the tumbler 15 and the nozzle in the key cylinder 14 are inserted as shown in Figure 16. The engagement with the housing 12 is released, and the key cylinder 14 can be rotated relative to the housing 12. Further, the bent end 4 la of the lever 41 is pressed radially outward by the dog 40, and is rotated around the pin 4 lc to be turned. -Moved to the same circumference as the outer surface of cylinder 14. Accordingly, the inner end 4 lb of the checkerboard 41 moves radially inward in FIG. 86. For this reason, when the cylindrical portion 62 is rotated, the inner end portion 41b comes into contact with the inclined surface 43c of the first locking member 43, and the return position is reduced. The first locking member 43 is moved inward in the radial direction against the elasticity of the ring 44.

When the key cylinder 14 is rotated through an angle of about 10 ° by destruction from the state where the check lever 41 is rotated, FIGS. 3 to 7, FIG. 18 and FIG. The state shown in FIG. 19 is changed to the state shown in FIGS. 49 to 52, respectively. As shown in FIG. 1, since the projection 16 a of the first opening 16 is engaged with the recess 13 d of the sleeve 13, the sleeve 13 The rotational motion of the first row-and-roller 16 is prevented by the concave portion 13d of the first row-wheel, and the first row-and-roller 16 can move in the axial direction. However, in a state where the key cylinder 14 and the sleeve 13 are connected by the tumbler 15, the sleeve 13 is forcibly rotated by a different key. When it is rotated, the first row 16 rotates with the sleeve 13. When the key cylinder 14 is rotated to an angle of 30 °, the cylinder power 14 a of the key cylinder 14 and the first rotor 16 are rotated. 1st mouth — evening '16 due to contact with ramp 16b, spaced from key cylinder 14 against the elasticity of rotor spring 21 It is moved in the axial direction to the position shown in Fig. 34. The recess 16 c of the first mouth 16 and the recess 17 c of the connector 17 are fitted with the protrusion 14 b of the key cylinder 14, Rotor 16 is the protrusion 1 4 b Move along. Due to the movement of the first rotor 16, the pair of outer protrusions 18 c of the second rotor 18 relatively enter the notch 16 d of the first mouth 16. You. As a result, the first mouth 16 and the second row 18 can rotate together. In addition, the check wrapper holding device 42 is located at the position shown in FIGS. 85 to 87. At an angle of 46.3 °, the check lever holding device 42 passes through the state shown in Figs. 88 to 90, and the key cylinder 14 is moved to 50 °. When rotated to this angle, the state shown in FIGS. 58 to 61 is obtained. At this time, the slope 16 b of the first row 16 contacts the cam projection 13 b of the sleeve 13. When the key cylinder 14 is rotated up to 60 °, the cam section 26 f, the nongager 30, the connector shaft 26 and the arm section 6 3 Is in the state shown in FIG. 109 to FIG. As shown in Fig. 11 1, as shown in Fig. 13 38, rocking load 3 2 is pressed by rods brig 38. Up to this point, the arm part 63 and the protruding part 64 are separated at a constant angular interval. This is because the arm 63 and the protrusion 64 are held in contact with each other, and the arm 63 and the protrusion 63 are projected during a tilt movement of 1 lb of the intermediate frame. This is because there is a risk that unexpected stress will occur between the protruding portions 64 and either one will be damaged.

After that, when the key cylinder 14 is rotated to an angle of 70 °, the inclined surface 16 b of the first opening 16 is turned into the cover 13 of the sleeve 13. It moves along the projection 13b, and the first row 16 is further moved in the axial direction. At this time, the protruding portion 14b of the key cylinder 14 and the wide portion 14c of the protruding portion 14b are fitted into the concave portion 16c of the first row roller 16 so that the key Even if the cylinder 14 is rotated in either the on direction or the mouth direction, the distance between the cylinder 14 and the first rotor 16 does not change. There is no play in rotation. In this state, the key cylinder 14 can pass through the ON position and rotate to the start position of 152 °. In other words, the check lever holding device 42 at the angle of 55 ° is in the state of FIG. 91 to FIG. 93 and at the angle of 85 ° FIG. 94 to FIG. When the key cylinder 14 is rotated 90 ° after passing through the state of 96, the state shown in FIGS. 66 to 69 is obtained. Cam section 26 f, non The gas 30, the connector shaft 26 and the arm unit 63 are in the state shown in FIGS. 11-12 to 11-14. At this time, as shown in FIG. 70, the driven portion 22 shown in FIG. 18 climbs over the inclined surface 12 c and the protruding portion 12 d to form the second recessed portion 12 2. Mated to f. The key cylinder 14 is 105. At the angle of, the states shown in FIGS. 115 to 117 are obtained. The cam section 26 f, the nogger 30, the connector shaft 26 and the arm section 63 are in the state shown in FIGS. 11-12 to 11-14. Further, when the check lever holding device 42 passes through the state shown in FIGS. 977 to 990 and rotates the key cylinder 14, the angle of 120 ° is obtained. As shown in Fig. 74, the cam section 26 f, non-gear 30, connector shaft 26 and arm section 63 are shown in Figs. The state shown in 120 is reached. At the angle of 152 °, the state shown in Fig. 75 to Fig. 77 is obtained, and the cam section 26 f, the non-rigger 30, the connector shaft 26 and the arm section 6 are provided. 3 is in the state shown in Figs.

Key cylinder 14 is about 100. When rotated up to this point, the cam groove 62b is rotated along the inner projection 19 of the intermediate frame 1lb, so that the cylindrical portion 62 is opened in the axial direction.ヅ King groove 3 It is moved to the 2 side. For this reason, the engagement between the cylindrical portion 62 and the second opening 18 is released, and the rotation of the delay device 60 is stopped. However, the connection of the second row 18 and the connector 25 causes the connector shaft 26 to rotate continuously, so that The ignition switch 28 is rotated to the start position. For this reason, the arm section 63 is moved from the position shown in Fig. 94 to the position shown in Fig. 123 and from the position shown in Fig. 123 to the position shown in Fig. 135. Does not rotate. This is due to the need for articulation between the intermediate frame 1 lb and the rear frame 1 lc. Immediately, when performing articulation between the intermediate frame 11b and the rear frame 1lc, the check lever holding device 42 is moved up to 152 °. It is not necessary to rotate, and it is necessary to prevent the rotation of the check lever holding device 42 in a state where the rotation is performed to 90 °. Therefore, the rotation of the key cylinder 14 thereafter causes the arm portion 63 of the connecting rod 61 to project from the protrusion 64 of the receiving member 29. The engagement is maintained, and the receiving member 29 is rotated together with the connector shaft 26.

When the cylinder 14 is returned to 120 ° from this state, the cam section 26 f, the non-rigger 30, the connector shaft 26 and the arc The memory section 63 is in the state shown in FIG. 124 to FIG. 126, and 105. When the key cylinder 14 is returned, the state shown in FIG. 127 to FIG. Key cylinders 14 to 90. When the angle is returned to the above angle, the lever lever holding device 42 is in the state shown in FIGS. 103 to 105. The key cylinder 14 is in the state shown in FIG. The cam section 26 f, the nongager 30, the connector shaft 26, and the arm section 63 are in the state shown in FIGS. 1330 to 1332. At this time, since the pin 22 contacts the contact surface 12 e of the cam surface 12 b, the key cylinder 14 is rotated toward the lock position. I can't do that. Then, when the key is pressed together with the cylinder 14 against the elasticity of the cylinder spring 52, the pin 22 is brought into contact with the contact surface 12e. The engagement between the contact surface 12 e and the pin 45 is released. For this reason, the key can be rotated to the lock position together with the key cylinder 14. When the key cylinder 14 is returned up to 60 °, the cam section 26 non-gear 30, the connector shaft 26 and the arm section 63 are shown in FIG. The state is as shown in Fig. 33 to Fig. 135, and when it is returned to 30 °, the state is as shown in Figs. The connector shaft 26 is rotated to the initial lock position.

However, if the key is not removed from the key cylinder 14, the second end will be pulled by the inner end 4 lb of the checkerboard. The protrusion 45b of the stop member 45 is held while being engaged with the contact surface 1lc of the intermediate frame 1lb shown in FIG. 94, and the check lever is held. 42 is held in the state shown in FIG. 94 to FIG. When the key is removed from the key cylinder 14, the inner end 4 lb of the checker wrapper 41 is separated from the first locking member 43. For this reason, the first locking portion 43 and the second locking portion 45 move radially due to the elasticity of the return spring 44, and the second locking portion The engagement between the protrusion 43b of the stop 43 and the 1 lb abutment surface 1Id of the intermediate frame is released. You. Due to this, the non-rigger 30 and the lock ring 32 are moved to the lock position by the elasticity of the load spring 38. Also, as shown in FIG. 1337, the half-moon-shaped portion of the receiving member 29 is moved to the mouth position by the movement of the non-rigger 30 so that the projecting portion is formed. 6 4 moves from FIG. 13 8 to the position of FIG. 14 1 together with the arm section 63. At this time, the protrusion 64 moves within the annular groove 26 b of the connector shaft 26. Accordingly, the cylindrical portion 62 can be moved from the position shown in FIGS. 100 to 102 to the position shown in FIGS. 85 to 87. The cam section 26 f, the nogger 30, the connector shaft 26 and the arm section 63 are in the state shown in Fig. 13'9 to Fig. 141, and The king road 3 2 moves from the unlock position to the lock position.

When the key cylinder 14 was rotated with a different key, the key cylinder 14 was connected to the nosing 12 by the tumbler 15. It is kept in the state and is rotated together with the knowsing 12. For this reason, since the cylinder 14 does not rotate relative to the housing 12, the first row 16 is the housing 1. Does not move in the axial direction relative to 2. Therefore, as shown in FIG. 17, the pole 37 has a V-shaped groove 13 of the sleeve 13 against the elasticity of the ball spring 36. It is pushed out from c. For this reason, the sleeve 13, the key cylinder 14, and the first mouth 16 are free to rotate together. In this case, since the relative rotation between the key cylinder 14 and the mouth 16 cannot be obtained, the key cylinder is connected via the first rotor 16. 14 does not connect to second row 18. Also, since the groove 17 b of the stopper 17 is held in a state of engaging with the projection 12 g of the nozing 12, the groove of the second lever Rotation is blocked.

In this embodiment, a tilt structure is provided by the axes 24 and 35, and the intermediate frame 1 lb is shown in FIG. 82 or FIG. 8 with respect to the rear frame 1 lc. As shown in FIG. 83, it is possible to rotate around the shafts 24 and 35, respectively.
