Description

  The present invention relates to a holding device for cables such as various flexible wires or electric cords composed of an inner and an outer, and a two-wheeled vehicle such as a bicycle using the same.

  Conventionally, for example, in a two-wheeled vehicle such as a bicycle, a functional component such as a brake and a transmission and an operation unit are linked with an operation cable such as a flexible wire composed of an inner and an outer, respectively. In the case of the electric assist type, an electric cord is also present.

  These operation cables and cables such as electric cords are usually stretched across the front and rear of the two-wheeled vehicle, and the middle of them is held by a frame via a holder.

  One of the holders is integrally formed of a synthetic resin with a storage space for holding the cable through the holder fixed to the frame of the two-wheeled vehicle and a hook portion for inserting and holding the cable from the side. (For example, refer to Patent Document 1).

  However, in this configuration, it is necessary to insert the cable into the storage space, and when applied to a plurality of cables, the workability is poor, and in the case where a part such as a connector is provided at the end of the cable, there is a difference in the storage space. There was an evil that could not be included.

  Further, although there is no such problem in the hook portion, there is a problem that the cable is easily disconnected when an external force is applied to the cable.

  In order to cope with such a problem, there has been proposed a structure in which a substantially U-shaped cable receiver is fixed to a frame of a motorcycle, and a reverse U-shaped cap is detachably engaged with the cable receiver to constitute a holder. (For example, refer to Patent Document 2).

  Then, the cable is first set in the cable receiver, and then the cap is attached to hold the cable.

Since the cable receiver is substantially U-shaped, the cable holding function cannot be exhibited by itself, and a cap must be attached each time.
JP 2002-240769 A JP 2004-17785 A

  In the configuration of Patent Document 2, since the cable holding function is exhibited only after the cap is attached, when handling a plurality of cables, the handling is bad and when an external force is applied to the cable. There is a problem that the cable receiver and the cap are disengaged and the cable is opened.

  The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide a cable holding device that can hold a cable rationally and easily.

  In order to achieve the above object, the present invention fixes a holder provided with a substantially ring-shaped holding wall for holding a cable to a mounting portion, and inserts the holder into the holding wall with an inclination with respect to the cable stretching direction. The cable is held in the holding wall by forming a groove and inserting the cable inclined in the holding space surrounded by the holding wall through the insertion groove and displacing the cable in the tension direction. is there.

  In this way, the cable can be easily stored in the holding space surrounded by the holding wall via the insertion groove only by slanting the cable, and the insertion groove is inclined with respect to the cable stretching direction. It becomes difficult to come off.

According to the cable holding device of the present invention, it is possible to easily fit the cable into the holding space surrounded by the holding wall through the insertion groove only by tilting the cable once, especially when it is applied to a plurality of cables. It can greatly enhance sex. In addition, since the insertion groove is inclined with respect to the cable stretching direction, it is difficult to come off.
By applying the cable holding device to a two-wheeled vehicle, it is possible to prevent loosening of a cable such as a flexible wire or an electric cord, and to eliminate the harmful effects such as the foot being caught on the cable, which is extremely effective in terms of safe driving.

  The embodiment of the present invention fixes a holder provided with a substantially ring-shaped holding wall for holding a cable to the mounting portion, and forms an insertion groove inclined with respect to the cable stretching direction on the holding wall, The cable is held in the holding wall by holding the cable in the holding wall by inserting the cable inclined in the holding space surrounded by the holding wall through the insertion groove and displacing the cable in the extension direction. This makes it easy to fit in the holding space surrounded by the holding wall via the insertion groove, and makes the insertion groove difficult to come off because it is inclined with respect to the cable stretching direction.

  The vertical width of the insertion groove is set to be slightly larger than the cable diameter having the maximum outer diameter for a plurality of cables having different diameters.

  In addition, it is desirable to set the inclination of the insertion groove, that is, the interval perpendicular to the cable stretching direction at the front and rear ends at the opposite groove edge of the insertion groove to be smaller than the outer diameter of the cable. If necessary, it is conceivable to increase the inclination so that the front and rear ends of the facing groove edge overlap in a direction perpendicular to the cable stretching direction.

  When placing the cable in the holding space via the insertion groove, it is better to set the inclination to the minimum necessary if the workability is given priority. On the other hand, if the cable holding capacity is increased, it is preferable to increase the inclination.

  Further, if the cover is detachably attached to the holder and the cable held by the holding wall is pressed, the cable can be held more reliably and the longitudinal movement can be prevented.

  Specifically, a pressing wall for pressing the cable is arranged at a predetermined distance from the top wall of the cover, and the top wall and the pressing wall are integrally connected via a leg portion, and the leg portion is inserted into the insertion groove. The cover is fixed to the holder by holding the holding wall between the top wall and the pressing wall in a state of being fitted to the holder.

  If the thickness of the pressing wall in the direction perpendicular to the cable stretching direction is varied, a plurality of cables with different diameters can be reliably held.

  In consideration of strength, the holder is made of a metal material, and the cover is preferably made of a synthetic resin material in order to improve operability.

  If these cable holding devices are arranged on a frame to make a two-wheeled vehicle that holds at least one of a plurality of operation cables and electric cords, the overall assemblability is improved and the cable is loosened due to inadvertent disconnection. Can be established and safety as a motorcycle can be established.

  Hereinafter, an example applied to a motorcycle, for example, a bicycle will be described with reference to the accompanying drawings.

  As shown in FIG. 7, the bicycle 1 of the present embodiment is configured such that when the pedal 3 disposed at the lower center of the frame 2 is stepped on, the force is transmitted to the chain via the crank 4 to drive the rear wheel 5. It has become. A fork 7 that pivotally supports the front wheel 6 is connected to a handle stem 9 that rotatably passes through a head tube 8 formed at the front end of the frame 2. A handle 11 having grips 10 attached to both ends is fixed to the upper portion of the handle stem 9, and these configurations are the same as those of a normal bicycle.

  At the rear end of the frame 2, a cantilever type stand device 13 is provided via a mounting plate 12. The stand device 13 includes a stand leg 14 that can be raised and lowered, and a stand spring 16 that has one end locked to the mounting plate 12 and the other end locked to a spring support plate 15 that is integral with the stand leg 14. The stand spring 16 exhibits the action of holding the stand leg 14 in a stable position in the up / down direction with a predetermined dead point as a boundary. Reference numeral 17 denotes a saddle, 18 denotes a locking device for the rear wheel 5, and 19 a denotes an inner and outer cable that links the handle lever 20 and the braking device for the rear wheel 5.

  The bicycle 1 according to the present embodiment enhances the crime prevention effect by locking the stand leg 14 as shown in the drawing and the state where the handle 11 is tilted by the lock device 21. That is, when the stand leg 14 is raised and the handle 11 is tilted to a predetermined angle, the lock device 21 works and this state can be held by locking.

  For this reason, the bicycle cannot be used. When the lock is released, the lock device 21 is deactivated via the lock release lever 22, so that the handle 11 and the stand leg 14 can be operated. That is, the bicycle is in use.

  The stand device 13 and the lock device 19 are linked via a cable 19b composed of an inner and an outer, like the previous braking cable.

  In this embodiment, the lock device 18 is also related to the lock of the handle 11 and the stand leg 14. That is, the lock device 18 is positioned above the lock device 21 and the lock device 21 cannot be released unless the lock device 18 is unlocked. That is, it is a form in which double safety measures are taken. For this purpose, another cable is stretched, but here, the explanation will be focused on holding the cables 19a and 19b.

  These cables 19 a and 19 b are stretched along the pipe 2 a of the frame 2, and the middle of them is held by the cable holding device 23.

  Hereinafter, the configuration of the cable holding device 23 will be described with reference to FIGS. In this example, in addition to the cables 19a and 19b, the transmission 19c and the cable 19d made of an electric cord for electrically connecting the generator and the lamp are also targeted.

  A holder 24 constituting a cable holding device 23 is fixed to the pipe 2a. The holder 24 is formed of a metal material such as an iron plate in consideration of strength, and is integrated with the pipe 2a through welding or a mechanical fixture.

  Further, the holder 24 has a bottom wall 25 that has an arc shape along the curved surface of the pipe 2 a, side walls 26 and 27 that rise substantially vertically from both sides thereof, and extends from a part of the side walls 26 and 27. Each of the holding walls 28 and 29 is bent inward, and the bottom wall 25, the side walls 26 and 27, and the portion surrounded by the holding walls 28 and 29 are set in the holding space 30. It is.

  The front ends of the holding walls 28 and 29 are opposed to each other with an interval to be the insertion groove 31. The insertion groove 31 is inclined with respect to the longitudinal direction of the pipe 2a, that is, the stretching direction of the cables 19a to 19d.

  Now, when the cables 19 a to 19 d are stored in the holding space 30, at least a part of the cables 19 a to 19 d is inclined and passed through the insertion groove 31, and is stretched straight when it is positioned in the holding space 30. Accordingly, when at least one of the cables 19a to 19d is viewed, due to the inclination of the insertion groove 31, a part of the holding walls 28 and 29 is positioned as a baffle wall just above the insertion groove 31, so that it does not come out accidentally. .

  As shown in FIG. 3A, the vertical width S of the insertion groove 31 is set slightly larger than the outer diameter D of the large-diameter cables 19a, 19b, 19d so that they can be inserted easily. The distance T perpendicular to the cable stretching direction of the opposite inner ends of the holding walls 28 and 29, that is, the front and rear ends of the opposing groove edge of the insertion groove 31, is smaller than the outer diameter of the small-diameter cable 19c so that each cable 19a-19d. It is surely prevented from coming out.

The interval T can be changed by the inclination angle of the insertion groove 31. The interval T increases as the inclination angle decreases, and conversely, the interval T decreases as the inclination angle increases.
For example, as shown in FIG. 3B, if the inclination angle is set so that the opposing groove edges of the insertion groove 31 overlap each other, the interval T is set to the interval T in FIG. The shape is just negative.

3A having a small inclination angle makes it easier to insert the cables 19a to 19d into the insertion groove 31, and the cable having the inclination angle shown in FIG. The holding ability of 19a to 19d can be set high, and the inclination angle may be arbitrarily selected according to the purpose of use of the cables 19a to 19d.
In the present embodiment, a cover 32 is detachably attached to the holder 24 in order to further secure the cable.

  As shown in FIGS. 4 to 6, the cover 32 is made of a synthetic resin and has a gate shape that covers the upper side of the holder 24 and both outer sides. A pressing wall 34 is provided at a predetermined distance from the inner surface of the top wall 33. The pressing wall 34 is integrated with the top wall 33 via a leg portion 35, and one of the intervals between the pressing walls 34 is set open and the other is closed.

  When the cover 32 is attached to the holder 24, first, the lower surface of the top wall 33 is applied to the upper surfaces of the holding walls 28, 29, and the upper surface of the pressing wall 34 is applied to the lower surfaces of the holding walls 28, 29, and then pressed in the longitudinal direction. Then, the leg portion 35 is engaged with the insertion groove 31 on the way, and then inserted until the holding walls 28 and 29 come into contact with the closed portions of the interval.

  The reason why the leg portion 35 is not engaged with the insertion groove 31 from the beginning of the pushing operation of the cover 32 as described above is that the insertion groove 31 is inclined and is engaged from the beginning. If the form is adopted, the inclination is obstructive, and the leg portion 35 is sufficient if it has a strength capable of connecting the top wall 33 and the pressing wall 34, and it is not necessary to increase the length.

  Here, the top wall 33 and the pressing wall 34 are shaped such that the holding walls 28 and 29 are sandwiched, whereby the cover 32 is fixed to the holder 24.

  In the above configuration, the cables 19a to 19d held in the holding space 30 of the holder 24 are lightly pressed by the pressing wall 34 of the cover 32, and can be prevented from shifting in the stretching direction (longitudinal direction). .

  In addition, when the outer diameters of the cables 19a to 19d are different, the pressing by the pressing wall 34 varies. As a countermeasure, the circumferential thickness of the pressing wall 34 (direction perpendicular to the cable stretching direction) is different. If the substantial height of the holding space 30 is changed by providing the cable, the small-diameter cable 19b can be securely clamped.

  The cover 32 may be attached as necessary. That is, if the cables 19a to 19d are to be securely held without being displaced, they are provided with a cover. In any case, the selection is made according to the cable stretching conditions.

  According to the embodiment described above, the cable can be easily held, and the cable can be very rationally inserted into the holding space by inclining the insertion groove. And since the holder is made of a metal material, even if a strong force is applied to the cable, it will not come off, and damage to the holder itself can be prevented.

  Further, if the cover is attached, the cable can be held more reliably and will not move in the longitudinal direction. As a result, a portion of the cable in the longitudinal direction is slackened by an external force, and the possibility of catching a limb or the like can be prevented.

  If this is applied to a two-wheeled vehicle, the entire assembly property is improved, and the limbs are not caught on the cable as described above, so that it can be used safely.

  It should be noted that the two-wheeled vehicle may be a bicycle, a power-assisted bicycle, an electric bicycle, a motorcycle, and the like, and it is needless to say that a three-wheeled vehicle also conforms to the spirit of the present invention.

  As described above, the cable holding device according to the present invention can be easily accommodated in the holding space surrounded by the holding wall via the insertion groove only by tilting the cable once, and is particularly suitable for a plurality of cables. Workability can be greatly improved in some cases, and the insertion groove is inclined with respect to the cable stretching direction, so that it is difficult to come off. There is a wide one.
