[Effect]

According to the above-mentioned means, by simply pushing the resin clamp holding the piping together into the inner side of the opposite side walls of the bracket fixed to the lower surface of the vehicle floor, which have a substantially U-shaped cross section, the resin clamps are formed at both ends of the resin clamp. The pair of guide walls facing each other are inserted into the opposing sides of the walls while being in contact with each other, and the fitting claws provided on the guide walls fit into the fitting holes of the both sides of the walls, thereby tightening the resin clamp. It can be fixed to the bracket and the pipes can be focused and fixed on the underside of the vehicle floor.

When removing the resin clamp from the bracket, move the guide wall side of at least one of the pair of guide walls formed at both ends of the resin clamp inward (from the center) of the pair of side walls formed on the bracket to the inner side of the bracket. By bending in the direction, the fitting hole provided on the bracket side and the fitting claw portion provided on the resin clamp side are disengaged, and the resin clamp is removed from the bracket.

Furthermore, since the resin clamp is fixed to the bracket, which has a roughly U-shaped cross section, through a pair of guide walls and is fixed to the inside of both side walls of the bracket, a flat surface at least the same size as the bottom of the bracket is attached to the vehicle floor. As long as it can be secured on the bottom surface, the bracket can be installed without impairing the attachment and detachment of the resin bracket.

〔Example〕

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

The drawings from Fig. 1 to Fig. 4 show an embodiment of this invention, and as shown in Fig. 4 when the car body (lower surface of the floor) is viewed from the ground side, there is a A plurality of pipes 2 such as fuel pipes and brake pipes are arranged near the trunk room at the rear of the vehicle, and these pipes 2 are bundled together.
It is held and fixed at several points on the lower surface 1 of the car body floor by resin clamps 3 and brackets 4. Specifically, as shown in FIG. By fixing to a bracket 4 fixed to the lower surface 1 of the floor, the piping 2 is converged and held on the lower surface 1 of the vehicle floor.

The structure for fixing the pipes on the lower surface 1 of the vehicle floor is constructed as described above, and as shown in FIGS. Fitting holes 41 are provided in both opposing U-shaped walls 42 of the bracket 4, which is formed to have approximately the same dimensions as the resin clamp 3 and has a substantially U-shaped cross section (see FIG. 2, which shows a perspective view of the bracket 4). ) as well as the fitting hole 41
A bracket 4 having a substantially U-shaped cross section is fixed to the lower surface 1 of the vehicle floor by spot welding or the like so as to open toward the ground (see FIG. 1).

Further, both ends 32 corresponding to guide walls of the resin clamp 3 are pushed into and clamped into the opposing side walls 42 of the bracket 4 having a substantially U-shaped cross section.
is formed into a plate shape extending toward the ground so as to have flexibility, and a portion of each end 32 facing each fitting hole 41 of the bracket 4 is provided with a plate shape that is flexible and extends toward the ground side. Fitting claw portions 31 are respectively formed to fit into each other (see FIG. 3, which shows a diagonal diagram of the resin clamp 3).

The resin clamp 3 is attached to the bracket 4 by bending and pushing the ends 32, which correspond to the guide walls, into the opposite side walls 42 having a substantially U-shaped cross section. By fitting the fitting claw portion 31 into the fitting hole 41 of the bracket 4 (see FIG. 1), the resin clamp 3 is clamped and fixed to the bracket 4.

Therefore, in order to collect and hold the pipes 2 on the lower surface 1 of the vehicle floor, a resin clamp 3 for collecting and holding the pipes 2, and a resin clamp 3 for securing the resin clamp 3 on the lower surface 1 of the vehicle floor are required. Since the bracket 4 and the bracket 4 fixed to the bracket 4 can be held and fixed by a one-touch operation, it is possible to reduce cost and weight by reducing working time and the number of parts.

Furthermore, the resin clamp 3 is fixed to the bracket 4, which has a U-shaped cross section, through both ends 32 corresponding to a pair of guide walls, and is fixed to the inside of both side walls 42 of the bracket 4, so that the resin clamp 3 comes into contact with the lower surface of the vehicle floor of the bracket. As long as a flat surface of at least the same size as the contacting portion can be secured on the lower surface of the vehicle floor, the bracket can be installed without impairing the ease of attaching and detaching the resin clamp 3. Therefore, the bracket can be installed without taking up much space, and there is a high degree of freedom regarding the placement position even on the narrow lower surface 1 of the vehicle body floor where many vehicle body components such as suspensions and propeller shafts are disposed. Furthermore, when removing the piping 2, use a screwdriver or the like to secure the resin clamp 3 by fitting the fitting holes 41 on both side walls 42 of the bracket 4 and the fitting claws 31 on both ends 32 of the resin clamp 3. By bending both ends 32, which correspond to at least one guide wall of the resin clamp 3, toward the inside of the bracket with a single tool, the fitting claw portion 31 and the U-shaped both walls 42, which correspond to the side wall portions of the bracket 4, are provided. It can be removed by unfitting the fitting hole 41. Therefore, not only the installation workability but also the removal workability is extremely easy, thereby improving the workability at a repair shop or a dealer after the vehicle is completed.

In the above embodiments (FIGS. 1 to 3), the resin clamp 3 is provided with a fitting claw portion 31, and the bracket 4 is provided with a fitting hole 41.
Reverse configuration, that is, a fitting hole is provided in the resin clamp 3,
The bracket 4 may be provided with a fitting claw portion so that the bracket 4 is fitted into the bracket 4.

[Effect of idea]

As mentioned above, this device consists of two parts: a resin clamp and a bracket with a U-shaped cross section.Moreover, when assembling the bracket and resin clamp, a pair of guide walls are formed at both ends of the resin clamp. Therefore, by simply pushing the resin clamp into the bracket, the guide walls are inserted into the facing inner side walls of the bracket, making it easy to assemble.

Furthermore, when removing the resin clamp from the bracket, at least one guide wall side of the pair of guide walls formed at both ends of the resin clamp is bent inward (from the center) of the pair of side walls formed on the bracket. , the fitting hole provided on the bracket side and the fitting claw portion provided on the resin clamp side are disengaged, and the resin clamp can be removed from the bracket. In this way, the resin clamp can be removed from the bracket by bending at least one of the guide walls within the space between the pair of facing side walls formed on the bracket, making it possible to remove the resin clamp in narrow spaces. It is also easy to remove.

Furthermore, since the resin clamp is fixed to the bracket, which has a roughly U-shaped cross section, through a pair of guide walls and is fixed to the inside of both side walls of the bracket, a flat surface at least the same size as the bottom of the bracket is attached to the vehicle floor. As long as the resin bracket can be secured on the lower surface, the bracket can be installed without impairing the attaching/detaching properties of the resin bracket, making it easy to install the bracket on the lower surface of the vehicle floor.
