Description

  The present invention relates to a cable guide device that holds a cable along a bicycle frame.

  In general, bicycles are provided with brake cables for front wheels and rear wheels that transmit the operation of the brake operation lever to the brakes of the front wheels and rear wheels. In addition, other cables may be provided, such as a gear for transmitting gears and an interlocking cable for interlocking a plurality of locks. In addition, electric bicycles supply power to control cables and headlamps that send control signals. A power supply cable or the like is provided. If these cables are installed at a position far from the frame, they may be caught in the driver's feet or hands, etc., which may impede driving or become dangerous. In order to improve safety, it is necessary to keep it along the frame.

  As a structure of the cable guide device that holds the cable along the frame in this way, for example, as shown in FIG. 8, a cable guide 53 having a hook-shaped portion 52 in which an insertion hole 51 is formed is used as the frame of the vehicle body. There is known a structure in which the cable 50 is fitted along the frame 55 by being fixed to the cable guide 53 by being welded to the cable 55 and inserting the cable 50 through the insertion hole 51 of the cable guide 53. With this structure, when the cable 50 is inserted into the insertion hole 51 of the cable guide 53, there is an advantage that the cable 50 can be reliably prevented from being detached from the insertion hole 51.

  However, such a configuration of the cable guide 53 has a disadvantage that can be applied only to the cable 50 in which at least one end of the cable 50 can be removed and nothing is attached. That is, in the case of an interlocking cable or a control cable in which a lock part or a terminal connected to various devices is attached to both ends, the parts attached to both ends are inserted into the insertion holes 51 of the cable guide 53. Therefore, the cable 50 cannot be inserted into the insertion hole 51 of the cable guide 53. Accordingly, as shown in FIG. 9, a cable guide 60 in which two holding projecting pieces 62 are projected from a base 61 while curving so as not to overlap each other is provided as shown in FIG. 55 is fixed by welding or the like, and the cable 50 is twisted between the holding protruding pieces 62 to be inserted obliquely and then rotated in the direction a. There is known a cable guide 60 configured to be able to hold 50 in a hooked state. This type of cable guide 60 does not need to be inserted through the insertion hole from the end of the cable 50, and therefore can be applied even if parts or the like are attached to both ends of the cable 50. A structure similar to the cable guide 60 is disclosed in Patent Document 1 and the like.

  According to this type of cable guide 60, the cable 50 such as the interlocking cable and the control cable can be held along the frame unless the cable 50 is twisted locally to return to the posture at the time of insertion. Can do.

  However, in order to fix the brake cable, the interlocking cable, the control cable, etc., both the cable guide 53 and the cable guide 60 must be fixed to the frame 55 by welding or the like. It takes time.

  On the other hand, a cable guide device that can hold a plurality of cables together is disclosed in Patent Document 2 and the like. As shown in FIG. 10, the cable guide device 70 is fixed to the vehicle body frame 75 by welding or the like, and has a recess 72 a that can accommodate a plurality of cables 71 side by side, and the cable receiver 72. The cap 73 is detachable from the cap 73. Then, outward claws 72 b are respectively formed at both ends of the cable receiver 72, and each of the claws 72 b is fitted into openings 73 a formed at both ends of the cap 73, whereby a plurality of cables 71 are connected. The cap 73 is configured to be locked to the cable receiver 72 while being accommodated side by side in the recess 72a.

  This cable guide device 70 has an advantage that a plurality of cables 71 can be held by only one cable guide device 70. In addition, after the cable receiver 72 is welded to the frame 75 of the vehicle body, the cable guide device can be accommodated with relatively little effort and time simply by accommodating a plurality of cables 71 and putting the cap 73 on the cable receiver 72 for engagement. 70 can be attached. Moreover, not only the brake cable but also the interlocking cable and the control cable can be held.

Japanese Utility Model Publication No. 61-26692 JP 2004-17785 A

  However, according to the cable guide device 70 as shown in FIG. 10, since the claw 72b of the cable receiver 72 is engaged in a state where it is exposed to the outside, any object or driver's hand or foot is attached to the claw 72b. The cap 73 may come off from the cable receiver 72 due to contact, and in this case, since all the cables 71 are also detached from the cable receiver 72 at the same time, the safety is extremely lowered. Further, when the driver's clothes are caught on the exposed portion of the cable 71 and the cable 71 receives an external force in a direction away from the frame 75, the cap 73 also receives a force in a direction away from the frame 75. There is a possibility that the cap 73 may come off from the cable receiver 72, and in particular, when an external force is received from a plurality of cables 71, the possibility that the cap 73 will come off from the cable receiver 72 is increased, and safety is reduced. . In addition, when the cap 73 is molded from resin, the cap 73 may become fragile due to secular changes when used for many years, and may come off.

  The present invention solves the above-mentioned problem, and can hold not only the brake cable but also the interlocking cable and the control cable, etc., and can be attached to the frame of the vehicle body without much time and effort. Provided is a cable guide device capable of minimizing the number of cables that can be disconnected, and can minimize the number of disconnected cables even if some cables are disconnected. For the purpose.

  In order to solve the above problems, the cable guide device of the present invention is a cable guide device that holds a cable along a bicycle frame, and is arranged in a posture surrounding an insertion hole through which the cable is inserted. And a cable holding member whose both ends are fixed to the frame, and a cable auxiliary holding member which is detachable from the cable holding member and forms an insertion space through which the cable is inserted between the cable holding member and the cable holding member. It is characterized by that.

  According to this configuration, a cable that can be inserted into the insertion hole such as a brake cable can be reliably prevented from being disconnected by being inserted into the insertion hole. That is, unless the cable holding member is removed from the frame or the cable is removed from the insertion hole, the cable inserted through the insertion hole does not come off. Also, for cables that cannot be inserted into the insertion hole, such as interlocking cables and control cables, the cable is held in the insertion space by attaching the cable auxiliary holding member to the cable holding member with the cable disposed in the insertion space. be able to. In addition, only the cable holding member needs to be fixed to the frame by welding or the like, and the cable auxiliary holding member may be attached to the cable holding member as necessary, so that it can be attached to the frame with relatively little effort and time. Can do.

Further, in the cable guide device of the present invention, an engaging portion that engages with the cable holding member is formed at both ends of the cable auxiliary holding member, and the engaging portion of the cable auxiliary holding member engages with the cable holding member. It is formed engaging hole portion is, the engaging portion, facing the engaged hole portion of the cable hold member while being rush toward the outside to the inside in the engaging hole portion It is engaged with the wall surface.

  According to this configuration, when the cable auxiliary holding member is attached to the cable holding member, the engaging portions formed at both ends of the cable auxiliary holding member are from the outside of the engaged hole portion of the cable holding member. Since it is engaged in a state of protruding inside, the engaging portion is not exposed to the outside, and other parts may come into contact with the portion exposed to the outside of the cable auxiliary holding member. The engaging portion is not detached from the engaged hole portion. Thus, once the cable auxiliary holding member is attached to the cable holding member, the cable holding member hardly detaches from the cable holding member, so that the possibility that the cable inserted into the insertion space is disconnected can be minimized. .

  In the cable guide device of the present invention, the width of the cable auxiliary holding member is formed smaller than the width of the cable holding member, and when the cable auxiliary holding member is attached to the cable holding member, the width direction of the cable holding member On the other hand, the cable auxiliary holding member is arranged and configured such that both side portions in the width direction are on the inner side than both side portions in the width direction of the cable holding member.

  According to this configuration, even if an object or a driver's hand or foot may come into contact with the cable holding member from the direction along the width direction, these objects or the like are usually on both sides in the width direction of the cable holding member. It becomes difficult to contact both sides in the width direction of the cable auxiliary holding member. Thereby, the possibility that the cable auxiliary holding member is detached from the cable holding member can be further reduced, and thus the possibility that the cable inserted into the insertion space is disconnected can be further suppressed.

  Further, the cable guide device of the present invention is provided with a plurality of bulge portions that receive a cable that is bulged outward and inserted through the insertion hole, and is provided between the bulge portions, and is recessed inward. A recess is formed to receive the cable inserted into the insertion space.

  According to this configuration, a plurality of cables can be held in a collective state as compared with a case where a plurality of cables are simply arranged side by side. Therefore, even when the number of cables is large, it is possible to arrange the cables while keeping the size of the cables arranged in the width direction of the frame small.

  In the cable guide device of the present invention, the cable auxiliary holding member is formed of a metal material having elasticity. According to this configuration, it is possible to prevent deterioration and damage due to secular change during long-term use, such as when the cable auxiliary holding member is formed of a resin material. The property is further improved.

  The cable guide device of the present invention is a cable guide device that holds a cable along a bicycle frame, and an insertion hole through which the cable is inserted is provided inside to surround the insertion hole from the periphery. The cable holding member is disposed in a posture and has both ends fixed to the frame, and an engaged portion is formed on the cable holding member to engage a cable auxiliary holding member that is detachable from the cable holding member. It is characterized by.

  According to this configuration, the cable that can be inserted into the insertion hole such as a brake cable is inserted into the insertion hole, so that the cable can be reliably prevented from coming off. That is, as long as the cable holding member does not come off the frame, the cable inserted through the insertion hole will not come off. If it is necessary to fix cables that cannot be inserted into the insertion holes, such as interlocking cables and control cables, add a cable auxiliary holding member that can be engaged with the engaged part of the cable holding member. The cable that cannot be inserted into the insertion hole can be fixed.

  In addition, the bicycle of the present invention is provided with the cable guide device having any one of the above-described configurations.

As shown in FIG. 1, the cable guide device is often arranged on the lower surface or side surface of a frame such as a main pipe. However, for easy understanding in FIGS. The apparatus is illustrated as being disposed on the upper side of a frame such as a main pipe.

  As shown in FIG. 1, a main pipe 2 as a frame of a bicycle (electric bicycle in FIG. 1) has a plurality of cable guide devices 10 at intervals in the axial direction (longitudinal method of the main pipe 2). These cable guide devices 10 hold a plurality of cables 3 along a frame such as the main pipe 2. In this embodiment, as the cable 3, for example, a rear wheel brake cable for operating the brake of the rear wheel 4, a gear shift for operating a transmission provided on the hub of the rear wheel 4 at a position near the handlebar. The machine cable, the control cable for controlling the assist rate of the auxiliary driving force of the electric motor, and the like are held, but are not limited thereto.

  As shown in FIGS. 2 to 6, the cable guide device 10 surrounds the insertion hole 12 through which the cable 3 is inserted from the periphery (more specifically, surrounds the insertion hole 12 together with the wall surface of the main pipe 2. And a cable holding member 11 whose both ends are fixed to the main pipe 2 as a frame by spot welding or the like, and is detachable from the cable holding member 11 and is attached to the cable holding member 11 when installed. A cable auxiliary holding member 14 that forms an insertion space 13 through which the cable 3 is inserted is provided. For example, the cable holding member 11 is formed by bending a relatively thick metal plate, and the cable auxiliary holding member 14 is formed by a thin metal material having elasticity such as a metal leaf spring. However, it is not limited to this.

  As shown in FIG. 5 and the like, the cable holding member 11 has a plurality (two in this embodiment) of receiving the cables 3 that bulge outward (in the direction away from the main pipe 2) and are inserted into the insertion holes 12. A bulging portion 11a, a hollow portion 11b that is provided between the bulging portions 11a and that is recessed inside and receives the lower half of the cable 3 inserted into the insertion space 13, and welded along the main pipe 2. The cable auxiliary holding member is formed with a fixed side portion 11d which is provided with a welded portion 11c and the like and forms both ends of the cable holding member 11 and a standing portion 11e which stands up from the fixed side portion 11d and continues to the recess portion 11b. 14f to be engaged, a mounting flat portion 11g on which the cable auxiliary holding member 14 is placed, and the like. The cable holding member 11 has, for example, a substantially M shape when viewed from the front, but is not limited to this shape. The engaged hole portion 11f does not necessarily have to have a hole shape penetrating to the inner side (insertion hole 12) of the cable holding member 11, but has a hole shape that is recessed from the outer side to the inner side of the cable holding member 11. May be.

  As shown in FIG. 6A and the like, the cable auxiliary holding member 14 includes left and right mounting surface portions 14a that extend in the lateral direction and are placed on the mounting flat portion 11g of the cable holding member 11 when mounted, and the mounting surfaces thereof. A curved receiving portion 14b that forms a insertion space 13 through which the cable 3 is inserted between the mounting surface portion 14a and the recess portion 11b of the cable holding member 11 when mounted, and the left and right mounting surface portions 14a. From the end portions of the arm portions 14c and the arm portions 14c along the upright portions 11e of the cable holding member 11 when being bent and extended from the end portions (when the cable auxiliary holding member 14 is attached to the cable holding member). An engagement portion 14d that is bent into an inverted triangle shape and enters the engaged hole portion 11f of the cable holding member 11 from the outside to the inside and engages with the wall surface facing the engaged hole portion 11f from above is provided. To have. As shown in FIGS. 2A and 3, the cable auxiliary holding member 14 is formed to have a width smaller than the width of the cable holding member 11, and the width of the cable holding member 11 can be reduced when the cable auxiliary holding member 14 is attached. Thus, both side portions in the width direction of the cable auxiliary holding member 14 are arranged and configured to be inside the both side portions in the width direction of the cable holding member 11.

  A cable that can be inserted into the insertion hole 12 of the cable holding member 11, such as a brake cable or a transmission cable (hereinafter also referred to as an insertable cable 3 </ b> A), is held in a state of being inserted into the insertion hole 12 of the cable holding member 11. The On the other hand, a cable larger than the opening of the insertion hole 12 of the cable holding member 11 is attached to both ends of a control cable (or an interlocking cable for interlocking a plurality of locks) or the like. A cable that cannot be inserted into the hole 12 (hereinafter also referred to as a non-insertable cable 3B) is placed on the recess 11b of the cable holding member 11 without the cable auxiliary holding member 14 being attached to the cable holding member 11 (insertion space). 13) is configured to be held by attaching the cable auxiliary holding member 14 so that the curved receiving portion 14b of the cable auxiliary holding member 14 is covered with the non-insertable cable 3B.

  In addition, when the number of cables 3 to be held is two or less and both are insertable cables 3A, the cable auxiliary holding member 14 is not attached to the cable holding member 11 as shown in FIG. The cable 3 is held only by the cable holding member 11. Further, even when all of the cables 3 to be held are the insertion-possible cables 3A, the number of these cables is larger than the number inserted through the insertion holes 12 of the cable holding member 11 (three in this embodiment). In this case, the cable auxiliary holding member 14 may be attached to the cable holding member 11 and the insertable cable 3A may be inserted into the insertion space 13 and held.

  According to the above configuration, the insertion-possible cable 3A that can be inserted into the insertion hole such as a brake cable is inserted into the insertion hole 12 of the cable holding member 11 fixed to the main pipe 2, thereby the cable 3 (insertable cable 3A). ) From the insertion hole 12 can be reliably prevented. Further, the non-insertable cable 3B such as the interlocking cable and the control cable cannot be inserted by attaching the cable auxiliary holding member 14 to the cable holding member 11 in a state where the non-insertable cable 3B is disposed in the insertion space 13. The cable 3B can be satisfactorily held.

  Further, only the cable holding member 11 needs to be fixed to the frame (main pipe 2) by welding or the like, and the cable auxiliary holding member 14 only needs to be attached to the cable holding member 11 as necessary. It can be attached to the frame (main pipe 2) in a short time, and the work efficiency when the cable guide device 10 is assembled can be improved.

  Further, according to the above configuration, when the cable auxiliary holding member 14 is attached to the cable holding member 11, as shown in FIGS. 2 and 3, the engagement formed at both ends of the cable auxiliary holding member 14. Since the portion 14d is engaged in a state of protruding from the outside to the inside of the engaged hole portion 11f of the cable holding member 11, the engaging portion 14d is not exposed to the outside, and the cable auxiliary holding member 14 is also exposed. The engaging portion 14d will not be disengaged from the engaged hole portion 11f even if another object (such as a driver's hand or foot) comes into contact with the portion exposed to the outside. As a result, once the cable auxiliary holding member 14 is attached to the cable holding member 11, the cable holding member 11 hardly detaches from the cable holding member 11. Therefore, the cable 3 inserted through the insertion space 13 (such as the non-insertable cable 3B). Can be minimized, and the reliability of the function of holding the cable 3 can be improved.

  Further, according to the above configuration, the width of the cable auxiliary holding member 14 is formed to be smaller than the width of the cable holding member 11, and when the cable auxiliary holding member 14 is mounted, both sides in the width direction of the cable auxiliary holding member 14 are Since the cable holding member 11 is arranged so as to be inside the both sides in the width direction, the object, hand, or foot from the direction along the width direction of the cable holding member 11 (the left-right direction in FIG. 2B). Even if they come into contact with each other, these objects or the like come into contact with both sides in the width direction of the cable holding member 11 and hardly come into contact with both sides in the width direction of the cable auxiliary holding member 14. As a result, an external force can be applied by hitting the cable auxiliary holding member 14 and the possibility that the cable auxiliary holding member 14 is detached from the cable holding member 11 can be further reduced. The possibility of disconnecting the inserted cable 3 (such as the non-insertable cable 3B) can be further suppressed, and the reliability can be further improved.

  Moreover, according to the said structure, the some bulging part 11a which receives the cable 3 (insertable cable 3A) bulged outside and inserted in the insertion hole 12 in the cable holding member 11, and these bulging parts 11a A plurality of cables 3 are simply arranged side by side by adopting a configuration in which a recess 11b that receives a cable 3 (such as a non-insertable cable 3B) that is provided in between and is inserted into the insertion space 13 is formed. Compared with the case where it is provided, the plurality of cables 3 can be held together in a compact state (a state in which the cross section is substantially triangular in FIGS. 2 and 3). Therefore, even when the number of cables 3 is large, the cables 3 can be arranged while keeping the dimensions of the arrangement positions of the cables 3 in the width direction of the frame (the main pipe 2 or the like) small. The cable 3 can be easily routed.

  In the above embodiment, the cable holding member 11 has two bulges 11a and one recess 11b therebetween, and the two cables 3 (insertable cables 3A) are inserted through the insertion holes 12. Although the case where one cable 3 (such as the non-insertable cable 3B) can be disposed in the insertion space 13 when the cable auxiliary holding member 14 is mounted has been described, the present invention is not limited to this. For example, as shown in FIG. 7, the cable holding member 11 is formed with three bulging portions 11 a and two hollow portions 11 b therebetween, and three cables 3 (insertable cables 3 </ b> A) are inserted into the insertion holes 12. Correspondingly, two cables 3 (such as the non-insertable cable 3B) can be arranged in the insertion space 13 by forming two curved receiving portions 14b in the cable auxiliary holding member 14 correspondingly. It may be configured. In this case, the five cables 3 can be arranged in a very small arrangement location (in the case of FIG. 7, a substantially trapezoidal cross section), which has a good appearance and a stable appearance.

  In addition, according to the above configuration, since the cable auxiliary holding member 14 is formed of a metal material, it is possible to prevent deterioration and damage due to aging during long-term use, such as when the cable auxiliary holding member 14 is formed of a resin material. Further, it is possible to prevent the cable 3 from coming off due to the deterioration or damage, and this also improves the reliability.

  In addition, in the said embodiment, although the case where the location which fixes the cable guide apparatus 10 was the main pipe 2 was described, it is not restricted to this, As an arrangement | positioning location (fixation location) of the cable guide apparatus 10, Of course, the present invention can be applied to the chain stay 5 that supports the rear wheel 4 and other frame portions. Moreover, although the case where this cable guide apparatus 10 was assembled | attached to the electric bicycle in FIG. 1 was illustrated in the said embodiment, it can apply also to two-wheeled vehicles, such as a general bicycle and a motorbike which are not electric. Moreover, although the cable holding member 11 is made of metal, the cable holding member 11 can be welded to the frame such as the main pipe 2 and reliably supported. However, the present invention is not limited to this, and a material having high rigidity. If it is.

  The cable guide device of the present invention can be particularly suitably used for bicycles, but is not limited to this, and can be applied to two-wheeled vehicles and three-wheeled vehicles other than bicycles.
