  As shown in FIGS. 9a and 9b, the conventional parking brake routing structure includes a pedal 103 for stepping on a parking brake provided in the vicinity of the driver's seat 102 of the automobile 101, and left and right rear wheels 104 of the automobile. It connects with the release lever of the brake mechanism 105 provided in this. The front end of one operation side cable 106 is connected to the pedal 103, and the rear end penetrates the floor panel 107 and goes out. The rear end of the operation side cable 106 is connected to the center of the equalizer 108, and the front end of the driven side cable 109 is connected to the left and right ends of the equalizer 108. The rear end of the driven cable 109 is connected to the release lever of the brake mechanism 105 described above.

  As shown in FIGS. 10 and 11, the operation side cable 106 is slidably guided by a pull control cable conduit 110 inside the automobile. The rear end of the conduit 110 is attached to the tip of the cylindrical portion 112a of the casing cap 112, and the casing cap 112 is attached to the floor panel 107 by a flange or bracket 112b provided around the cylindrical portion. A known pull control cable is used for the operation side cable 106 and the conduit 110. The left and right driven cables 109 are also slidably guided by a pull control cable conduit 113. The distal ends of the conduits 113 are fixed to cylindrical casing caps 114, respectively. The casing caps 114 are attached to the floor panel 107 or the like directly or via a bracket (not shown).

  Recently, due to the expansion of the interior space of automobiles and the reduction in floor space associated with the universal design, there is a case where an equalizer installed outside the vehicle is placed indoors to secure an equalizer installation space. In that case, it is conceivable to extend the driven cable 109 and the conduit 113 in the room, but it is desirable to arrange them between the floor panel 107 and the floor carpet in order to improve the appearance.

  In Patent Document 1, a floor-side driven cable is formed on the floor panel so as to protrude along the front-rear direction, and a lower portion is provided on the upper surface of the floor tunnel, and an equalizer is disposed at the lower portion. A parking brake mounting structure is disclosed. In this mounting structure, a conduit is attached to the outer end portion of the support pipe that penetrates the floor panel, and the inner cable (driven cable) coming out from the inner end portion of the support pipe is guided into the floor tunnel. In this case, a hard resin console is put on the upper part of the floor tunnel, so that the inner cable is not exposed in the room. There is no need to cover it with a floor carpet.

  Patent Document 2 discloses a grommet that seals between a hole formed in a vehicle body panel or the like and an electric wire passing through the hole. A plurality of annular protrusions are formed on the inner surface of the grommet, and elastically contact with the surface of the electric wire passing through the inner surface of the grommet to provide a sealing action.

  In the case of Patent Document 1, since the inner cable is guided into a console constituted by a floor tunnel, there is no problem even if the driven cable is exposed. However, when there is no room in the floor tunnel and the inner cable is guided between the floor panel and the floor carpet, or when the parking brake cable (control cable) combining the cable and the cable is passed, the assembling work is difficult. In other words, when the parking brake cable is to be attached after the floor carpet is attached, it is difficult to pass the vehicle from the vehicle body penetration portion under the floor carpet because the gap is small and the floor carpet is not flexible. In order to make it easier to pass the parking brake cable, it may be possible to provide a cutout in the floor carpet, but the body frame (floor panel) can be seen, so it does not look good.

An object of the present invention is to provide a wiring structure that can be easily assembled and used when a driven cable (inner cable) is passed through a floor panel portion covered with a floor carpet .

The parking brake wiring structure according to the present invention (Claim 1) has one end arranged at the driver's seat of the automobile and the other end connected to the equalizer, one end connected to the equalizer, and the other end.

In the parking brake wiring structure of the present invention (Claim 1), a rigid guide pipe is disposed between the floor panel and the floor carpet in advance, and the parking pipe is driven when the parking brake cable is assembled. The side cable (inner cable) can be passed. Since the inner cable is flexible, the operation through the guide pipe is easy. It is not necessary to peel off the floor carpet when assembling the cable, and it is not necessary to pass the cable along the conduit between the floor panel and the floor carpet. Therefore, the parking brake cable can be easily assembled to the vehicle body. In addition, since the rear ends of the pair of guide pipes pass through the floor panel and protrude to the outside of the vehicle, the driven cable is fixed from the outside of the vehicle to the guide pipe fixed between the floor panel and the floor carpet. Easy to assemble.

When the end portion of the conduit that guides the driven cable to the brake mechanism is connected to the rear end portion of the guide pipe projecting outside the vehicle via a casing cap (Claim 2), The driven cable can be passed through the guide pipe and then a casing cap fixed to the end of the conduit can be connected to the guide pipe. Therefore, the assembling work is easier.

FIG. 6 and FIG. 7 are partially cutaway side views showing another embodiment of the pipe / conduit connection structure of the parking rake routing structure of the present invention, and FIG. 8a is the present invention. perspective view showing an embodiment of a pipe coupling structure by spring clips related to routing structure of the parking brake, Fig. 8b and 8c side view and a cross-sectional view of the middle assembly of the pipe coupling structure, Fig. 8d and FIG. 8e Respectively partially shows a state after assembled middle and assembly of the pipe coupling structure is a cross-sectional side view.

  A wiring structure 10 shown in FIG. 1 includes an operation side cable 11, a pair of driven side cables 12, 13, and an equalizer 14 that connects the rear end of the operation side cable 11 and the front end of the driven side cable. . The operation side cable 11 is slidably guided by the operation side conduit 15. One driven side cable 12 is slidably guided by a first guide pipe 16 and a first driven side conduit 17 connected to each other. The other driven side cable 13 is also slidably guided by the second guide pipe 18 and the second driven side conduit 19. The front sides of the first guide pipe 16 and the second guide pipe 18 extend substantially straight, and the rear side is gently curved toward the outside. And the rear end penetrates the floor panel P which divides the inside and outside of the vehicle, and protrudes outside the vehicle. The front ends are respectively locked to brackets (see reference numeral 59 in FIG. 8) attached to the floor panel P. An imaginary line Pa indicates the rising portion of the floor panel. In FIG. 1, the left side of the imaginary line Pa is inside the vehicle and the right side is outside the vehicle. The first guide pipe 16 and the second guide pipe 18 are disposed between the curved floor panel P and the floor carpet K.

  As shown in FIG. 2, the front end (left side of FIG. 2) of the operation side cable 11 is connected to a pedal (or operation lever) BP for operating a parking brake. Then, while being guided by the conduit 15, it reaches the vicinity of the lower portion of the driver's seat 20, and the rear end is connected to the central portion of the equalizer 14 (see FIG. 1). The first driven-side conduit 17 connected to the rear end of the first guide pipe 16 extends rearward while being curved, and is connected to the brake mechanism 21 of the right rear wheel. On the other hand, the second driven side conduit 19 extends to the left side so as to cross the automobile and is connected to the brake mechanism 22 of the left rear wheel. Each driven conduit 17, 17 is located outside the vehicle, as can be seen from the dashed lines in FIG.

  The operation side cable 11 is a cable that transmits pulling force, such as a stranded cable in which metal strands are twisted together. In particular, the inner cable (inner of a pull control cable provided with a synthetic resin coating on the outer periphery of the stranded wire. Cable).

  The conduit 15 of the operation side cable 11 is preferably a pull control cable conduit (outer casing) comprising an armor layer spirally wound with a metal wire having a square cross section and a synthetic resin coating layer provided on the outer surface thereof. . It is also possible to use a synthetic resin tube (liner) fitted to the inner surface of the armor layer. The operation side cable 11 and the conduit 15 can be constituted by a normal pull control cable. The direction can be changed by a pulley or the like without using the conduit 15. However, the combination with the conduit 15 is preferable because it is easy to route and the operation side cable 11 can be protected. The front end of the conduit 15 is fixed to a base bracket or the like of an operation pedal through a casing cap, and the rear end is fixed to the floor panel by a cap 24 or the like as shown in FIG. Further, as shown in FIG. 2, the middle of the conduit 15 may be held by a bracket 25.

  The equalizer 14 uniformly transmits the operating force of the operation side cable 11 to the two driven cables 12 and 13, and a conventionally known one is used. Such an equalizer 14 is manufactured by folding a metal plate at the rear end side and bending it into a U-shaped cross section. A hole or a notch is formed in the center for pivotally locking the cable end fitting of the operation side cable 11, and the holes for locking the rope end fittings of the driven side cables 12, 13 are pivoted on both sides thereof. Or a notch is formed. A synthetic resin equalizer can also be used.

  For the driven cables 12 and 13, a pull control cable inner cable similar to the above can be used. In addition, as for the first and second driven side conduits 17 and 19, a pull control cable conduit corresponding to the inner cable can be used.

  The first guide pipe 16 and the second guide pipe 18 can slidably receive the driven side cables 12 and 13, and easily pass the driven side cables 12 and 13 from the rear end side during assembly. There is no particular limitation on the material and thickness as long as the inner diameter can be reached. However, since it is provided on the lower surface of the floor carpet K, it is preferable to use a metal pipe having such a rigidity that it will not be crushed when stepped on. As the metal, steel, aluminum, copper alloy or the like is used. In addition to metals, pipes made of synthetic resin can also be used. As long as the pipe satisfies the above conditions, it is preferable that the pipe be as thin as possible. A tube-shaped liner made of synthetic resin may be fitted to the inner surface of the metal pipe. The first guide pipe 16 and the second guide pipe 18 are somewhat different in shape and length, but have substantially the same configuration. Therefore, hereinafter, the first guide pipe 16 and the second guide pipe 18 will be described by using the second guide pipe 18 as a representative. Call.

  As shown in FIG. 3a, the planar shape of the guide pipe 18 extends straight at the front end side and curves outward at the rear end side. And as shown in FIG. 3b, the shape seen from the side gradually descends from the front side toward the rear side. Such two-dimensional bending of the metal pipe can be performed, for example, by pressing. This bent shape is adapted to the curved state of the floor panel P and varies depending on the type and shape of the automobile. The floor carpet is cut or curved to match such a three-dimensional curve. An intermediate portion of the guide pipe 18 is held by a bracket 26, and the bracket 26 is attached to a channel member C fixed to the floor panel P. The bracket 26 is fixed to the guide pipe 18 by brazing or the like.

  At the front end of the guide pipe 18 (left side in FIG. 3), an annular ridge 27 is formed as a seating surface to be attached to the floor panel. As shown in FIGS. 4 and 5, a diameter-expanded portion 28 is formed at the rear end of the guide pipe 18 in a cup shape. An annular step portion 29 that is substantially perpendicular to the axis is formed between the enlarged diameter portion 28 and a normal thickness. Such a diameter-expanded portion 28 and the annular ridge 27 can be formed by plastic deformation by press working or a working tool for piping.

  As shown in FIG. 4, a grommet 30 is attached around the vicinity of the rear end of the guide pipe 18. The grommet 30 includes a flange portion 32 fitted to the inner edge of the opening portion 31 formed in the rising portion Pa of the floor panel, and a cylindrical fixing portion 33 fitted to the outer periphery of the enlarged diameter portion 28 of the guide pipe 18. And a cylindrical close contact portion 34 extending continuously from the fixed portion, and a bellows portion 35 for airtightly connecting the flange portion 32 and the fixed portion 33. On the inner surface of the fixed portion 33, a step portion 33 a that engages with the outer surface of the step portion 29 of the guide pipe 18 is provided. In addition, two annular protrusions 36 are provided in parallel around the fixed portion 33. A clamp 36 a made of a thin metal plate or the like is caulked between the annular ridges 36. Thereby, the space between the grommet 30 and the guide pipe 18 is sealed.

  In this embodiment, the flange portion 32 is provided obliquely with respect to the guide pipe 18. This is based on the shape of the automobile floor panel. In some cases, the guide pipe can be provided at a right angle. The grommet 30 is made of a rubber material such as natural rubber or synthetic rubber, a synthetic resin elastomer, or other elastic material having processability.

  As shown in FIG. 5, the close contact portion 34 of the grommet 30 has a narrow inner diameter, thereby forming a stepped portion 34 a that engages with the tip of the enlarged diameter portion 28. A plurality of inner surface protrusions 37 are provided on the inner surface of the close contact portion 34. In this embodiment, the cross-sectional shape of the inner surface protrusion 37 is a substantially triangular shape, whereby an annular lip corresponding to the apex of the triangle is obtained. These inner surface ridges 37 are portions (lip portions) that elastically contact the outer peripheral surface of a casing cap 38 fixed to the end of a second driven side conduit (hereinafter simply referred to as a conduit) 19 connected to the guide pipe 18. ). Thereby, the gap between the casing cap 38 and the grommet 30 is sealed, and the gap between the casing cap 38 and the guide pipe 18 is indirectly sealed. Further, the inner surface protrusion 37 has a retaining action for preventing the casing cap 38 from coming off when the rear surface side (the right side in FIG. 5) of the flange 40 of the casing cap 38 abuts. In addition, since tension | tensile_strength acts on an inner rope after an assembly | attachment and compression force is added to the conduit | pipe 19 as the reaction force, big force is not added to the direction which pulls out the casing cap 38.

  The casing cap 38 is a cylindrical member as shown in FIG. 5, and engages with a tip end portion 39 inserted into a portion 18 a having a normal inner diameter of the guide pipe 18 and a stepped portion 29 of the enlarged diameter portion 28. A flange 40, a cylindrical portion 41 inserted into the inner surface protrusion 37, and a thin cylindrical conduit fixing portion 42 for caulking the conduit are provided. A conduit insertion hole 43 is formed on the inner surface of the conduit fixing portion 42, part of which reaches the cylindrical portion 41. A passage 44 for passing an inner cord is formed at the distal end side of the conduit insertion hole 43. As a result, a step 45 is formed between the passage 44 and the conduit insertion port 43, where the tip of the conduit 19 abuts. A front surface side (left side in FIG. 5) of the flange 40 is formed with a tapered surface 46 so as to be easily inserted into the enlarged diameter portion 28. Moreover, since there is a round at the corner where the cylindrical inner peripheral portion of the enlarged diameter portion 28 and the stepped portion 29 are continuous, there is also a function of avoiding the round. The connection structure 47 for connecting the guide pipe 18 and the conduit 19 is an embodiment of the pipe / conduit connection structure of the present invention.

  When assembling the routing structure 10 configured as shown in FIG. 1, first, the two guide pipes 16 and 18 are installed on the floor panel P, and the rear end side is projected from the opening to the outside. At that time, the grommet 30 is also attached between the guide pipes 16 and 18 and the floor panel P. Then, a conventionally known floor carpet K is laid on the guide pipes 16 and 18. Then, the driven cables 12 and 13 are inserted into the guide pipes 16 and 18 from the outside, respectively, and connected to the equalizer 14 locked to the end of the operation cable 11. Further, as shown in FIG. 5, the casing caps 38 of the driven side conduits 17 and 19 are inserted into the enlarged diameter portions 28 of the guide pipes 16 and 18 from the outside, and the flanges 40 abut against the stepped portions 29. The clamp 36a may be crimped in advance, or may be crimped after the casing cap 38 is inserted.

  As described above, in this routing structure 10, the guide pipes 16 and 18 are installed in advance between the floor panel P and the carpet K, so that the routing work of the driven cables 12 and 13 is easy. Further, since the guide pipes 16 and 18 and the driven side conduits 17 and 19 are connected via the grommet 30, no tool is required for the connecting work, and the work is completed with almost one touch.

  A connecting structure 50 shown in FIG. 6 is a casing cap having a guide pipe 18 formed by fixing an enlarged portion 28 separately formed at the rear end of a pipe body 51 and a flange 40 locked in the enlarged portion 28. 38, an annular seal 52 attached to the front end 39 of the casing cap, and a clip 54 that engages the rear surface 53 of the flange 40 of the casing cap. In this embodiment, the stepped portion 29 of the enlarged diameter portion 28 has a conical shape, and is disposed somewhat forward from the end surface 51 a of the pipe body 51. And the enlarged diameter part 28 and the pipe main body 51 which are made to contact | abut the flange 40 with the end surface 51a of the pipe main body 51 are fixed by brazing. The seal 52 is a conventionally known one made of rubber or the like.

  The clip 54 is a well-known pinch type in which a pinch portion and a knob portion are formed by bending a spring steel wire or the like. The enlarged diameter portion 28 is formed with two slits 55 facing each other for inserting a clip portion of the clip 54. The clip 54 is previously sandwiched in the slit 55 using its elasticity. When the casing cap 38 is inserted, the tapered surface 46 of the flange 40 pushes the clip 54 open, and after the flange 40 passes, the clip 54 closes and engages the rear surface 53 of the flange 40. Although this connecting structure 50 has more parts than the connecting structure 47 of FIG. 4, the clip 54 engages with the rear surface 53 of the flange 40 and thus has a high retaining action.

  The connection structure 57 shown in FIG. 7 is substantially the same in shape of the guide pipe 18 as the connection structure 47 of FIG. 4 with the slit 55 of FIG. 6 formed in a cup shape at the rear end of the pipe by plastic deformation. Forming. On the other hand, the annular seal 52 attached to the front end portion 39 of the casing cap and the clip 54 engaged with the rear surface 53 of the flange 40 of the casing cap are substantially the same as those in the connection structure 50 of FIG. Both the connecting structure 50 in FIG. 6 and the connecting structure 57 in FIG. 7 can connect the conduit 19 to the guide pipe 18 with a single touch, and provide a sealing and retaining action.

  The connection structure 58 shown in FIG. 8 a is for connecting the tip of a pipe such as the guide pipe 18 and the bracket 59. A through hole 60 is formed in the bracket 59, and two annular protrusions 61 and 62 are spaced from each other at the distal end portion of the guide pipe 18 inserted into the through hole 60 as shown in FIG. 8b. Is formed. A taper is formed on the annular protrusion 61 on the distal end side. The spring clip 63 includes a substantially cylindrical support portion 64 and a locking piece 65 protruding from the upper end of the support portion. A notch portion 66 is formed in the lower portion of the support portion 64 in the longitudinal direction, so that it can be expanded and contracted elastically. The support portion 64 can be put on the outer periphery of the guide pipe 18 between the annular projections 61 and 62 in an expanded state, and can be attached to the portion by elastic contraction (FIG. 8b, FIG. 8). 8c). The spring clip 63 can be formed of a thin plate-shaped spring steel or the like. A spring clip made of synthetic resin can also be used.

  The locking piece 65 extends obliquely rearward from the vicinity of the center of the upper end of the support portion 64 in the front-rear direction. The locking piece 65 is elastically deformable and is bent inward by the inner peripheral edge of the through hole 60 when the distal end portion of the guide pipe 18 with the spring clip 63 attached is passed through the through hole 60. Therefore, as shown in FIGS. 8 d and 8 e, the tip can be passed through the through hole 60. Once passed, the locking piece 65 rises elastically, and its free end is hooked on the surface of the bracket 59. As a result, the pipe can be assembled to the bracket 60 with one touch, and after the assembly, the retaining action is achieved.

  In addition, when attaching the above-mentioned guide pipe 18 to the floor panel vicinity of a motor vehicle, after engaging the guide pipe 18 with the bracket 60 as mentioned above, the guide pipe 18 and the bracket 60 are actually brazed, Fasten the brazed bracket to the floor panel of the vehicle with screws. As described above, the use of the spring clip 63 facilitates attachment to a floor panel or the like. The number of the locking pieces 65 is not limited to one and may be two or more. The support part 64 can also be made into a cylinder shape without providing a notch part. In that case, fix to the pipe with adhesive or caulking. Note that a locking piece may be directly cut out at the end of a pipe such as the guide pipe 18.

  In the case of FIG. 2, the front ends of the pair of guide pipes 18 are arranged in the center portion of the floor panel, but may extend under the driver seat or the passenger seat. In that case, the equalizer and the operation side cable are arranged under the seat.
