DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a piping clamp embodying the present invention will be described below with reference to the drawings. Here, FIG. 1 is an overall perspective view of a pipe clamp showing an embodiment of the present invention, and FIG. 2 is an overall perspective view showing a state where the pipe is held by the pipe clamp. FIG.
FIG. 3 is a perspective view of a clamp body, which is a state before a cushion material described later is attached by insert molding.
4 is a right side view of the pipe clamp shown in FIG. 1, FIG. 5 is a front view seen from the direction of arrow A in FIG. 4, and FIG. 6 is a sectional view taken along line BB in FIG. is there.

As shown in FIG. 1, the pipe clamp 1 of this embodiment comprises a clamp body 2 and a cushion member 7 made of a rubber material such as an elastomer. The clamp body 2 is a member manufactured by molding a synthetic resin material such as polyacetal, for example, and has a substantially triangular overall shape that expands downward in a side view and has a rounded upper portion. . In the clamp body 2, two pipe fitting portions 3 and 9 each having a substantially C-shape in a side view and opening forward are formed in a line up and down, and formed integrally with these pipe fitting portions 3 and 9. The rear part 4 thus formed is formed linearly and obliquely. Further, a fixing portion 11 is formed on the lower end portion 6 extending in the horizontal direction so as to protrude downward for attachment to a vehicle panel (not shown). Further, from both sides of the plate-shaped portion 8 of the clamp body 2, a flange portion 10 protruding laterally is formed along the outline.

The pipe fitting portions 3 and 9 are portions for fitting and holding the pipe 5 together. In the pipe fitting portion 3, in particular,
A cushion member 7 for preventing vibration is insert-molded and attached in order to attach a pipe having much vibration.
Examples of the piping having a lot of vibration include a piping for an air conditioner of an automobile and a piping connected to a compressor. On the other hand, since the pipe with relatively little vibration is attached to the pipe fitting section 9, unlike the pipe fitting section 3, the cushion member 7 is not provided. As shown in FIGS. 3 and 4, four through holes 3a, 3b, 3c, 3d are formed near the pipe fitting portion 3 of the clamp body 2. Further, on the outside of the pipe fitting portion 3, FIGS.
As shown in FIG. 6, reinforcing ribs 13 are formed in order to improve the strength of the clamp body 2, particularly the pipe fitting portion 3. The through-hole 3c is formed in the reinforcing rib 13 and the through-hole 3c.
d is formed on the plate-like portion 8.

As shown in FIGS. 1 and 4, the cushion member 7 is attached by insert molding rubber such as elastomer so as to cover the pipe fitting portion 3 of the clamp body 2. They are integrally connected via two through holes 3a to 3d. Therefore, the cushion material 7
Can be clamped on the clamp body 2 without bonding with an adhesive or the like.
It is extremely firmly fixed. As shown in FIGS. 1, 4 and 5, a plurality of ridges are provided at predetermined intervals on the inner side of the cushion member 7, that is, on the surface of the portion where the pipe 5 is fitted and abutted. When the is fitted, an uneven bead 7a formed parallel to the length direction of the pipe 5 is formed. The uneven bead 7a is connected to the fitted pipe 5
This is formed in order to prevent the slippage from occurring, thereby holding the pipe 5 more firmly. In the pipe clamp 1 configured as described above, as shown in FIG. 2, the pipe 5 is held by fitting the pipe 5 to the pipe fitting portion 3.

As is apparent from the above description, according to the piping clamp 1 of the above embodiment, the cushion member 7
Is mounted on the clamp body 2 side, so that the problem of displacement of the cushion material does not occur unlike the conventional configuration in which the cushion material is wound around the pipe. In addition, there is no need to lengthen the cushion material more than necessary unlike the prior art, so that there is an advantage that there is no waste in material. Further, the cushion member 7 is provided with a through-hole 3 a formed in the clamp body 2.
There is also an advantage that it is not necessary to apply and bond an adhesive since the insert molding is performed integrally through the steps 3d to 3d.

Further, since the cushion member 7 is provided so as to cover around the pipe fitting portion 3, there is also an effect of preventing generation of abnormal noise. Further, since the bumps 7 are formed on the cushion material 7, the fitted pipe 5
Can be prevented, and the pipe 5 can be held more firmly.

Note that the present invention is not limited to the above-described embodiment, and various changes can be made without departing from the gist of the present invention. For example, in the above embodiment, the clamp body 2 is formed of polyacetal, but may be formed of another resin material. Further, the cushion member 7 is formed of an elastomer, but may be formed of another rubber material.

In the above embodiment, the clamp body 2
Although the four through holes 3a to 3d are formed around the pipe fitting portion 3, the through holes need not necessarily be formed. Also,
The number of through holes is not limited to four, but may be four or more, or may be less than four. Further, a through hole penetrating the pipe fitting portion 3 in the radial direction may be used.

In the above embodiment, the cushion member 7
Are integrally attached to the clamp body 2 by insert molding. However, the cushion material 7 may be attached to the clamp body 2 after being separately molded.

Further, the uneven bead 7a is formed on the surface of the portion where the pipe 5 of the cushion material 7 is fitted and brought into contact.
The present invention is not limited to an embodiment in which a plurality of ridges are formed as shown in FIG. For example, the surface may be formed in a jagged shape, or a plurality of warp-shaped protrusions may be formed on the surface. In short, it is only necessary that the surface portion of the cushion material be processed so as to prevent the pipe from slipping and to hold the pipe more firmly.

Further, in the above embodiment, the fitting portion 3 is formed more firmly by the reinforcing ribs 13. However, if the strength can be sufficiently secured, it is not necessary to provide the reinforcing ribs 13.

[0019]

As is apparent from the above description,
According to the pipe clamp of the first aspect, at least one through hole is formed in the pipe fitting portion of the clamp body, and the cushion material is integrally formed through the through hole. Therefore, since the cushion material is integrally formed via the through-hole, the cushion material is firmly fixed to the clamp body without using an adhesive, and there is an effect that no displacement occurs.

Further, according to the pipe clamp of the second aspect, the surface of the portion of the cushion material that contacts the pipe is formed in an uneven shape. Therefore, in addition to the above-described effects, the uneven surface formed on the cushioning material prevents the fitted pipe from slipping, so that the pipe is held extremely firmly.

According to a third aspect of the present invention, the surface of a portion of the cushion material that contacts the pipe is formed in an uneven shape. Therefore, the uneven surface formed on the cushioning material prevents slippage of the fitted pipe, so that the pipe is held extremely firmly.
