Description

[Detailed Description of the Invention] This invention relates to a mounting holder for holding parts such as moldings, oil supply pipes, cords, etc., which are mainly installed on the body side of an automobile. This type of retainer, which is generally called a molding clip or a hose clip depending on the purpose, is removably attached to the body side in consideration of the need for reuse and measures such as weight reduction and rust prevention. Grommet-type clips have been widely used in the past, which use a synthetic resin grommet nut for the part that is held, and the part that directly hangs the part is molded integrally with the grommet nut. Due to this, there is a natural limit to the holding force for parts, and it is not suitable for implementation when high holding force and strength are required. For this reason, in recent years, while grommet nuts are used, those in which the above-mentioned hanging portion is made of metal are being used. However, the joining and integration of two dissimilar materials requires extremely difficult technology, which increases the number of assembly steps, complicates the joining means, and makes the holder itself difficult to handle and large. There was a problem.

The present invention was developed in view of the above-mentioned conventional problems, and its purpose is to improve the technology of connecting a grommet nut made of different materials and a hanging part, and to provide a mounting holder with a simple structure that facilitates handling and reuse. This is what we provide.

The present invention will be explained below based on examples.

The mounting holder of this example is constructed by removably assembling a grommet nut 1 (also simply referred to as a grommet) which is removably fitted to the body B as a molding clip and a molding holder 7 to each other. . First, a grommet 1 made of synthetic resin has a pair of engaging pieces 3 protruding from a rectangular base plate 2 and facing elastically in the opening/closing direction via a groove 4.
A pair of locking pawls 5 protrudes from the other side of the holder. A screw hole 6 is formed from the center of the base plate 2 to between the facing surfaces of both engaging pieces 3. Note that guide surfaces 3a for fitting into the mounting holes 15 of the body B are formed on the outer surfaces of both engaging pieces 3. Further, a guide surface 5a is formed on the outer surface of the locking pawl 5 for fitting the hanging tool 7 into the locking hole 13.
A locking step portion 5b is formed at the terminal end of a. However, the claws 5 may be formed facing inward.

On the other hand, the hanging tool 7 is formed from a thin plate spring plate into a rectangular shape that fits the mounting area of the body B, and hook-shaped hooks are provided on each side of the base plate 8 to hook portions m on each side edge of the molding M. The piece 9 and the L-shaped latching piece 10 that abuts the inner edge of the engaging part m are formed independently from each other via a U-groove 11, so that each piece 9, 10 has appropriate elasticity. A screw hole 12 and a locking hole 13 are formed in the center of the base plate 8. Note that the distance L between the locking holes 13 and the distance L between the locking claws 5 are matched with each other.

Therefore, the grommet 1 and the hanging tool 7, which are made of different materials and configured as described above, can be sandwiched together based on a simple fingertip operation.
The locking claw 5 is illustrated in the order of A, B, and C in Figure 2.
enters the corresponding locking hole 13 while being elastically deformed, and is locked by the locking step portion 5b, allowing the base plate portions 2 and 8 to be assembled in close contact with each other. In addition, for disassembly, the tips of both locking claws 5 protruding from the outer surface of the base plate 8 are displaced inwardly, and each locking hole 1 is
Grommet 1 and hanging tool 7 can be removed by simply disengaging grommet 1 from 3.
They can be separated without any problem.

Therefore, when using the molding clip of this example and attaching it to the relevant part of the body B, as shown in FIG. By fitting the grommet 1 into the mounting hole 15, both the engaging pieces 3 are compressed elastically and are press-fitted together via the mutual guide surfaces 3a, and the base plate 2 is in tight contact around the mounting hole 15. Installed. Then, screw the screw 14 between the holes 6 and 12 of both 1 and 7 while tightening it. As a result, both engaging pieces 3 of the grommet 1 are opened and expanded appropriately due to an effect similar to that of driving a wedge, and the grommet 1 is loosened relative to the mounting hole 15 by being connected together with the screw 14, and no gas buildup etc. It is firmly fitted without any curling. At the same time, the hanging tool 7 is also firmly fixed to the outer surface of the body B.
Therefore, by press-fitting the required molding M into the holder 7, the molding M can be kept stable for a long period of time by utilizing the elastic force that can be exerted between the latching piece m, the latching piece 9, and the latching piece 10. Can be held.

The holder of this embodiment may be installed in any order by fitting the grommet 1 into the body, assembling the hanging tool 7 to the grommet 1, and tightening the screw 14. Furthermore, before use, the holder itself can be stored as a single component by assembling both 1 and 7 and temporarily tightening the screws 14 as necessary.

In addition, the hooking piece 9 formed on the clip hooking tool 7
Instead, it can be used as a clip for hoses or cords by integrally molding a gripping portion having a predetermined length at its tip that can be bent to grip a hose or cord.

As described above, the mounting holder of the present invention is a reusable clip that is lightweight and rust-proof, and consists of a synthetic resin grommet nut that is removably attached to the body of an automobile, and a screw attached to this nut. Since a locking pawl and a locking hole that are releasably engaged with each other are formed on both substrate parts of the metal hanging tool to be tightly connected, the grommet nut and the hanging tool are made of different materials. Even if they are the same, both can be properly attached and detached. In particular, by requiring both of the assembling means to be a locking pawl and a locking hole, the structure can be made extremely simple and the entire holder can be made compact. Moreover, since it can be assembled by simply fitting the locking pawl and the locking hole, it is easy to handle and requires no effort.

As described above, the mounting holder of the present invention can skillfully assemble the grommet nut and the hanging tool, which are made of different materials, as described above. Even an unskilled person can easily perform the installation because it can be accurately installed with a small number of work steps based on the operations of fitting the grommet nut and tightening the screw.
