<Example 1>
A first embodiment embodying the present invention will be described below with reference to FIGS. The pipe clamp A of the present embodiment is configured by assembling a clamp body 10 made of synthetic resin and two pipe holders 20 made of synthetic resin. The pipe clamp A is a member for supporting the two pipes P on the vehicle body B of the automobile shown in FIG.

  The pipe clamp A is attached to a bracket 40 fixed to the vehicle body B while holding the two pipes P. By attaching the pipe clamp A to the bracket 40, the two pipes P are supported with respect to the vehicle body B by changing the direction in three directions individually. As the pipe P, for example, an electric vehicle or a hybrid vehicle having a function of shielding or protecting a wire harness (not shown) can be applied.

  As shown in FIGS. 7 to 10, the clamp main body 10 is a single part including a base portion 11 having a thick plate shape and an attachment portion 12 connected to one end portion in the length direction of the base portion 11. Both front and back surfaces of the base portion 11 are flat assembly surfaces 13 having a substantially rectangular shape. The assembly surface 13 on the front side is formed with a pair of support wall portions 14 that protrude in a rib shape along both side edges in the long side direction. A pair of support wall portions 14 projecting in a rib shape along both side edges in the long side direction are also formed on the back side assembly surface 13.

  One end portion of the support wall portion 14 is connected to the mounting portion 12, but the other end portion of the support wall portion 14 is a free end. At the free end of the support wall 14 on the front surface side, a locking projection 15 (locking portion according to the claims) is formed that protrudes from the inner surface (the surface facing the paired support wall 14). Yes. Of the outer surface of the locking projection 15, the surface facing the assembly surface 13 is a retaining surface 16. Of the outer surface of the locking projection 15, the surface opposite to the assembly surface 13 is a guide slope 17 that is inclined with respect to the assembly surface 13. A pair of locking projections 15 are also formed on the free end portion of the support wall portion 14 on the back surface side, like the support wall portion 14 on the front surface side.

  Both free end portions of the support wall portion 14 on the front surface side and the back surface side can be slightly elastically bent. Therefore, the pair of locking projections 15 protruding so as to face each other on the front surface side can be elastically displaced in a direction away from each other. The pair of locking projections 15 that protrude so as to face each other on the back side can also be elastically displaced in a direction away from each other.

  A mounting space 18 is formed inside the mounting portion 12. As shown in FIGS. 2 and 10, a plate-like bracket 40 is inserted into the mounting space 18. Inside the mounting space 18, the lock protrusion 19 engages with the lock hole 41 of the bracket 40. Although this locking structure is not shown in detail, it is well known. And by this latching action, the attaching part 12 (clamp main body 10) is fixed to an attachment state with respect to the bracket 40 (vehicle body B).

  The two pipe holders 20 assembled to one clamp body 10 are the same type of parts. As shown in FIGS. 11 to 16, the pipe holder 20 includes a first arc-shaped portion 21 having a substantially semicircular arc shape, a second arc-shaped portion 22 having a substantially semicircular arc shape, a hinge portion 23, and an assembly portion 24. And a single part. First protrusions 25 are formed at both ends in the circumferential direction of the first arcuate portion 21, and second protrusions 26 are formed at both ends in the circumferential direction of the second arcuate portion 22.

  The first arc-shaped portion 21 and the second arc-shaped portion 22 are connected by a hinge portion 23 at one end portion in the circumferential direction so as to be relatively displaceable. As shown in FIG. 16, both arcuate portions 21 and 22 are always in an open state so that the inner peripheral surfaces do not correspond to each other. Then, when the arc-shaped portions 21 and 22 are relatively displaced with the hinge portion 23 as a substantial fulcrum so as to form a substantially cylindrical shape, the first protrusion 25 and the second protrusion 26 are engaged, and the arc-shaped portions 21 are engaged. , 22 are locked in a substantially cylindrical combined state. The pipe P is held in a state where the pipe P is inserted into the holding hole 27 formed by the union of both the arc-shaped parts 21 and 22.

  The assembly part 24 is a form protruding from the outer surface of the first arcuate part 21. The assembly portion 24 has a regular hexagonal shape whose outer periphery is constituted by six side portions 28. The protruding end surface of the assembly portion 24 is a flat abutting surface 29 having a regular hexagonal shape. Each of the six side portions 28 is formed with a locking recess 30 (the locking portion described in the claims). All the locking recesses 30 have the same shape and dimensions. A region of the inner surface of the locking recess 30 that is in a back-to-back positional relationship with the abutting surface 29 is a locking surface 31.

  When using the pipe clamp A of the present embodiment, a step of attaching the clamp body 10 (pipe clamp A) to the bracket 40 of the vehicle body B, and a step of constructing the pipe clamp A by assembling the clamp body 10 and the pipe holder 20. And the process of holding the pipe P in the pipe holder 20 is performed. The order in which these steps are performed is arbitrary. Hereinafter, an example of the usage pattern of the pipe clamp A will be described.

  First, the clamp body 10 in a state where the pipe holder 20 is not assembled is attached to the bracket 40 of the vehicle body B. Next, the two pipe holders 20 are assembled to the clamp body 10 in accordance with the direction of wiring of the two pipes P in the vicinity of the clamp body 10. When assembling the pipe holder 20, the assembly portion 24 of the pipe holder 20 is brought close to the assembly surface 13 of the clamp body 10 so as to enter between the pair of support wall portions 14. . In the process of entering, the assembly portion 24 interferes with the guide slope 17 of the pair of locking projections 15, so that the support wall portion 14 is elastically bent by the inclination of the guide slope 17.

  When the abutment surface 29 of the assembly portion 24 comes into contact with or approaches the assembly surface 13, the pair of support wall portions 14 are elastically restored, and the pair of locking projections 15. Is fitted into the pair of locking recesses 30. Then, the retaining portion of the locking projection 15 is locked to the locking surface 31 of the locking recess 30. By this locking action, the assembly portion 24 is held in a state of being fitted between the pair of support wall portions 14, and the pipe holder 20 is locked to the clamp body 10 in the assembled state. In addition, when assembling the pipe holder 20 to the clamp main body 10, both the arc-shaped portions 21 and 22 may be in an open state or a combined state.

  Thereafter, the pipe P is attached to the pipe holder 20. At this time, if both arc-shaped parts 21 and 22 are united, the second arc-shaped part 22 is removed from the first arc-shaped part 21 and the inner peripheral surface of the first arc-shaped part 21 is opened. Then, the pipe P is brought into contact with the inner peripheral surface of the first arc-shaped portion 21, and then the second arc-shaped portion 22 is united with the first arc-shaped portion 21. Thereby, both arc-shaped parts 21 and 22 hold | maintain so that the pipe P may be pinched | interposed.

The direction of assembly of each pipe holder 20 with respect to the clamp body 10 and the relative positional relationship (direction) of the two pipe holders 20 are not limited to those shown in FIGS. By appropriately turning the pipe holder 20 around the center of the regular hexagonal assembly portion 24 as a fulcrum, it can be arbitrarily changed and set.

  The pipe clamp A of the present embodiment includes a pipe holder 20 that can hold a pipe P, a clamp body 10 that is attached to a vehicle body B for supporting the pipe P in a predetermined routing path via a bracket 40, a clamp A locking projection 15 formed on the main body 10 and a locking recess 30 formed on the pipe holder 20 are provided. The locking protrusion 15 and the locking recess 30 can be locked in a plurality of forms in which the direction of the pipe holder 20 with respect to the clamp body 10 is different. According to this configuration, the orientation of the pipe holder 20 with respect to the clamp body 10 can be changed by changing the locking form of the locking protrusion 15 and the locking recess 30. Therefore, the pipe clamp A of the present embodiment can cope with a change in the arrangement direction and the arrangement route of the pipe P.

  Further, the pipe holder 20 is formed with an assembly portion 24 whose outer periphery forms a regular polygon (regular hexagon), and a plurality of (six) side portions 28 constituting the outer periphery of the assembly portion 24 are respectively connected to the pipe holder 20. A stop recess 30 is formed. According to this configuration, the orientation of the pipe holder 20 relative to the clamp body 10 can be changed by changing the orientation of the assembly portion 24.

  Further, the locking projections 15 are arranged on both the front and back surfaces of the clamp body 10. According to this configuration, both the front and back surfaces of the outer surface of the clamp body 10 can be effectively utilized as an assembly space for the pipe holder 20.

  Further, the locking projection 15 of the locking projection 15 of the clamp body 10 and the locking recess 30 of the pipe holder 20 can be elastically displaced. According to this configuration, the locking protrusion 15 of the clamp body 10 and the locking recess 30 of the pipe holder 20 can be locked simply by making them approach.
