DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a pipe clip for holding various pipes such as a fuel pipe and a brake hydraulic pipe of an automobile.

[0002]

2. Description of the Related Art As a conventional pipe clip of this kind, there is one disclosed in Japanese Patent Application Laid-Open No. Hei 7-310864. Although not specifically shown, the conventional clip is formed with a plurality of grooves for holding a pipe on a substrate, and the grooves are formed inwardly at the upper edges of both side walls individually defining the grooves. In addition to providing a pair of upper elastic pieces extending obliquely, a pair of lower elastic pieces corresponding to the upper elastic pieces is provided at the bottom of each concave groove, and a pair of projections are provided on inner surfaces of both side walls. I have.

When the small diameter pipe is held under the clip having such a configuration, the small diameter pipe is pushed into the corresponding concave groove while bending the pair of upper elastic pieces. When the small-diameter pipe is held between the tip of the lower elastic piece and the tip of the pair of lower elastic pieces, and conversely, when holding the large-diameter pipe, the large-diameter pipe is similarly bent while bending the pair of upper elastic pieces. Are pushed into the corresponding concave grooves, the distal ends of the pair of upper elastic pieces and the pair of lower elastic pieces are deformed to hold the large-diameter pipe. In particular, in the case of a large-diameter pipe, rattling in the left-right direction is effectively prevented.

[0004]

Therefore, in the conventional clip, when holding a large-diameter pipe, it is possible to prevent rattling as such with the help of a pair of projections. However, when holding a small diameter pipe,
Since it is only held between the tip portions of the pair of upper elastic pieces and the pair of lower elastic pieces, unnecessary rattling in the vertical and horizontal directions cannot be denied.

SUMMARY OF THE INVENTION The present invention has been developed in order to effectively solve the problems of the conventional pipe clip, and the invention according to claim 1 has side walls on both side edges of the substrate. In a pipe clip which stands up and holds a pipe in a groove defined between the side walls, a pair of upper elastic pieces extending inwardly and inclined inward from each other are provided at an upper end edge of each side wall. A pair of lower elastic pieces that protrude inward from each other and are provided between the upper edge of each side wall and the substrate, and a pair of holding pieces that bulge inward in an arcuate manner are provided on both sides of the substrate. It was adopted.

According to a second aspect of the present invention, on the premise of the first aspect, both side walls are divided into two block portions, an upper elastic piece and a lower elastic piece are provided on one block portion side, and the other block portion is provided. A configuration in which a clamping piece is provided on the side is adopted.

According to a third aspect of the present invention, based on the second aspect, a configuration is adopted in which the upper side of the other block portion provided with the pressing pieces is thinner than the lower side.

According to a fourth aspect of the present invention, based on the first to third aspects, a configuration is adopted in which the maximum bulging portion of the pressing piece is set to coincide with the center of the maximum diameter pipe that can be held. .

Therefore, in the first aspect of the present invention,
In addition to holding the upper elastic piece and the lower elastic piece in the vertical direction, it is possible to clamp both sides of the pipe with a pair of bow-shaped pressing pieces.
In particular, when a small-diameter pipe is held, the small-diameter pipe can be held without play in the vertical and horizontal directions, and an absorption allowance for a difference in diameter of the pipe is increased as compared with a conventional pipe.

According to the second aspect of the present invention, since the upper elastic piece, the lower elastic piece, and the pressing piece are provided in separate block portions on the side wall, the pipe is pushed into the concave groove. And the adjustment of the holding force of the pipe can be performed for each block part, so that the adjustment of the holding force of the pipe as a whole becomes easy.

According to the third aspect of the present invention, since the pressing piece having the bow shape is in a double-supported state, it has a higher bending rigidity than the upper elastic piece and the lower elastic piece in the cantilevered state and is bent. Although it is difficult, the upper part of the other block part where the clamping piece is provided is made thinner than the lower part, so that the mouth part when the pipe is pushed in is easily bent, and the workability is good. Become. On the other hand, after passing through the mouth portion, the holding piece is connected and fixed to the substrate side, so that the pipe is held with high rigidity.

According to the fourth aspect of the present invention, since the setting is made so as to coincide with the center of the largest diameter pipe capable of holding the largest bulging portion of the clamping piece, it is necessary to hold the large diameter pipe. As a result, the clamping force of the clamping piece always acts toward the center of the large-diameter pipe, so that the large-diameter pipe can be effectively prevented from coming off.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a pipe clip according to a preferred embodiment of the present invention. As shown in FIGS. 1 and 2, left and right side walls 2 are integrally erected on both side edges of the upper surface side of the substrate 1 so as to be formed in a concave groove 3 defined between the side walls 2. An anchor-shaped engaging leg 4 for engaging a mounting hole formed in a panel is provided at the center of the lower surface of the substrate 1 so as to be integrally formed with the lower surface of the substrate 1. I have.

In this embodiment, on the premise of such a configuration, the left and right side walls 2 are divided into two block portions 2A and 2B via slits 5, and one of the two side portions 2A and 2B is paired. As shown in FIG. 3A, a tall block 2A is formed as a tall block 2A, and the other is formed as a tall block 2B. A pair of upper elastic pieces 6 are provided on the upper end edge of the upper elastic piece 6 and extend inclining inward from each other.

For the short block 2B,
As shown in FIG. 3B, a pair of clamping pieces 8 bulging inward in a bow shape are provided between the upper end edge and the substrate 1 in a state of being held at both ends, and the clamping pieces 8 are provided. The upper part of the block part 2B is made thinner than the lower part, and the maximum bulging part of the pressing piece 8 is set to coincide with the center of the maximum diameter pipe that can be held. In the figure, 9
Is a pedestal for receiving the large-diameter pipe when holding the large-diameter pipe.

Accordingly, when the pipe is positioned at a predetermined position on the panel and held by using the pipe clip having such a configuration, if the small-diameter pipe 10A is to be temporarily held, first, the anchor-shaped engaging member is required. The stop leg 4 is attached to the mounting hole H of the panel P.
When the small-diameter pipe 10A is pushed into the concave groove 3 from the upper opening of the clip to obtain a state in which the clip itself is fixed to the panel P side, the one tall block portion 2A side has a pair of The upper elastic piece 6 is bent to allow the small-diameter pipe 10A to pass therethrough, and the small-diameter pipe 10A is held by the distal end of the upper elastic piece 6 and the corresponding distal end of the lower elastic piece 7, and the other short part is short. On the block 2B side, the pair of clamping pieces 8 are deformed according to the diameter of the small diameter pipe 10A,
Since both sides of A are to be clamped,
As shown in (1), the small-diameter pipe 10A is held.

In particular, the small diameter pipe 10A is held between the pair of holding pieces 8 in addition to the holding of the upper and lower elastic pieces 6, 7 in the vertical direction. In the holding state, the small-diameter pipe 10A is free from wobbling in the vertical and horizontal directions.

When holding the large-diameter pipe 10B, the large-diameter pipe 10B is inserted into the groove 3 through the upper opening of the clip.
When it is pushed in, the pair of upper elastic pieces 6 is bent on the one tall block portion 2A side, allowing the large-diameter pipe 10B to pass and obtaining a state in which the large-diameter pipe 10B abuts on the pedestal 9. The lower end of the lower elastic piece 7 is held by the end of the upper elastic piece 6 and the corresponding end of the lower elastic piece 7.
On the side, the pair of clamping pieces 8 are deformed according to the diameter of the large-diameter pipe 10B, and clamp both sides of the large-diameter pipe 10B. As a result, as shown in FIG.
0B will be held.

In particular, the holding of the large-diameter pipe 10B is set so as to coincide with the center of the largest-diameter pipe capable of holding the largest bulging portion of the holding piece 8 as described above. The clamping pressure by the piece 8 always acts toward the center of the large-diameter pipe 10B, so that the large-diameter pipe 10B can be effectively prevented from coming off. When the small-diameter pipe 10A is held, the small-diameter pipe 10A is pressed in the pull-out direction due to the deformation of the holding piece 8, but in this case, the amount of deformation of the holding piece 8 is small, and Since the force itself is small, it is not so much a problem.

In this embodiment, the side wall 2 is
The upper elastic piece 6 and the lower elastic piece 7 are divided into two tall block parts 2A.
The pressing piece 8 is provided for the other short block 2B, so that the pipe can be easily pushed into the groove 3 and each block 2A, 2A.
The holding force of the pipes 10A and 10B can be adjusted for each B, and the adjustment of the holding force of the pipes 10A and 10B can be easily adjusted as a whole.

Further, since the clamping piece 8 having a bow shape is in a double-supported state, it has a higher bending rigidity than the upper elastic piece 6 and the lower elastic piece 7 in the cantilevered state, and is hardly bent. In the embodiment, since the upper side of the block portion 2B of the side wall 2 provided with the clamping piece 8 is made thinner than the lower side, the mouth portion when the pipes 10A and 10B are pushed in is particularly bent. It becomes easy and workability becomes good. On the other hand, after passing through the mouth portion, the holding pieces 8 are connected and fixed to the substrate 1 side, so that the pipes 10A and 10B are held with high rigidity.

[0022]

As described above, according to the present invention, according to the first aspect of the present invention, in addition to holding the upper elastic piece and the lower elastic piece from the up and down direction, the both sides of the pipe have an arc shape. Since it becomes possible to clamp with a pair of clamping pieces presented,
Not only large-diameter pipes, but also small-diameter pipes, in particular, can hold small-diameter pipes without play in the vertical and horizontal directions. Become.

According to the second aspect, since the upper elastic piece, the lower elastic piece, and the pressing piece are provided separately in separate block portions on the side wall, the work of pushing the pipe into the concave groove becomes easy. At the same time, it is possible to adjust the holding force of the pipe for each block portion, and it is easy to adjust the holding force of the pipe as a whole.

According to the third aspect of the present invention, since the clamping piece having a bow shape is in a double-supported state, it has a higher bending rigidity than the upper elastic piece and the lower elastic piece in the cantilevered state, and is hardly bent. Since the upper side of the other block portion on which the pressure piece is provided is made thinner than the lower side, in particular, the mouth portion when the pipe is pushed in is easily bent, and the workability is improved.
On the other hand, after passing through the mouth portion, the holding piece is connected and fixed to the substrate side, so that the pipe is held with high rigidity.

According to the fourth aspect of the present invention, since the maximum swelling portion of the holding piece is set to coincide with the center of the largest diameter pipe capable of holding the holding piece, when holding the large diameter pipe, the holding piece is pressed. The clamping pressure by the piece always acts toward the center of the large-diameter pipe, so that the large-diameter pipe can be effectively prevented from coming off.
