Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a retainer attachment that can easily attach a retainer and can reliably prevent the retainer from falling off after attachment.

[0002]

[Prior art]

 Generally, a retainer is widely used when mounting an interior panel and an exterior panel for a vehicle, and examples of such a retainer mounting tool include, for example, Japanese Utility Model Publication No. 52-137411 and Japanese Utility Model Publication No. 59-19639. As shown in the official gazette, it is known that the retainer mounting surface of the fixture main body is provided with a retainer guide hole and a retainer mounting hole between them, with a narrowed passage through which the retainer neck can forcibly pass. There is.

However, in this type of conventional retainer mounting tool, when the retainer is moved from the retainer guide portion to the retainer mounting hole, a large force is required to forcefully pass through the narrowed passage between the retainer mounting portion and the retainer mounting portion. The diameter of the narrowed passage may increase due to wear or damage when the narrowed passage is forcibly passed through the narrowed passage, and the retainer may drop off during subsequent panel transportation, resulting in defective products. There was a point.

[0004]

[Problems to be solved by the device]

 The present invention solves the above-mentioned conventional problems and requires no great force to move the retainer from the retainer guiding part to the retainer mounting hole, and can be performed very easily. The present invention has been completed with the object of providing a retainer mounting tool that can significantly improve the performance of the retainer and can reliably prevent the retainer from falling off during transportation after mounting.

[0005]

[Means for Solving the Problems] A retainer mount of the present invention made to solve the above-mentioned problems is a retainer neck part between a retainer guide part and a retainer mounting hole on a retainer mount surface of a mount body. In the retainer fitting provided with a stenosis passage that can be forcibly passed through, a buffer hole was provided to assist the stenosis passage being expanded by the retainer neck that passes around the stenosis passage. It is characterized by.

[0006]

[Action]

 The retainer fitting thus configured guides the retainer inserted into the retainer guide portion to the retainer mounting hole through the narrowed passage, and fixes and mounts the retainer to the mounting body at the retainer mounting portion. Similar to the fixture, but since a buffer hole is provided in the peripheral portion of the stenosis passage to help the stenosis passage being expanded by the retainer neck, the expansion of the retainer when passing through the retainer. Since the opening force is elastically absorbed by the relaxation hole, the retainer can be guided with an extremely small force, and since the narrowed passage is not worn or damaged when passing through the retainer, the narrowed passage is expanded. The diameter can be prevented, and the retainer can be reliably prevented from falling off thereafter.

【Example】

 The present invention will now be described in detail with reference to the illustrated embodiment. In the figure, reference numeral 1 denotes an attachment body formed of an elastic synthetic resin or a wood-based material formed on an interior panel 20 for an automobile, and 2 denotes a retainer attachment surface of the attachment body 1. A circular hole-shaped retainer guide portion 4 having a sufficient space for inserting the retainer on the mounting surface 2 and a circular hole-shaped retainer mounting hole 5 having a smaller diameter than this are forcedly passed through the retainer neck. It is provided with a narrow constriction passage 3 interposed therebetween, and these points are similar to those of the conventional retainer fixture. In addition, although the retainer guiding portion 4 has a circular hole shape, the retainer guiding portion 4 may have a cutout shape having an end open to the outside.

Reference numeral 6 indicates that the neck of the retainer pushes the narrowed passage 3 when the neck of the retainer 10 passes through the peripheral portions on both sides of the narrowed passage 3, that is, substantially the center of the retainer guiding portion 4 and the retainer mounting hole 5. There is provided one buffer hole 6 for elastically absorbing the expanding force generated in the above and assisting the expansion of the narrowed passage 3. The buffer hole 6 may be provided only in the peripheral portion of either one of the narrowed passages 3, and the shape thereof may be a circular hole shape as shown in FIG. 1 or an arc shape as shown in FIGS. It may be in the shape of a ball or a plurality of balls may be provided in both peripheral portions as shown in FIG.

With the above-described structure, after the locking plate portion 11 of the retainer 10 is inserted into the retainer guiding portion 4, the neck portion having a reduced diameter between the locking plate portion 11 and the packing portion 12 is inserted. 13 is guided and passed through the narrowed passage 3 to the retainer mounting hole 5, where the retainer mounting surface 2 is sandwiched between the locking plate portion 11 and the packing portion 12, so that the retainer 10 is attached to the mounting body 1. The retainer mounting surface 2 is fixed to be used in a state in which the engaging projection 14 is projected from the retainer mounting surface 2. However, as described above, the retainer neck is passed through the peripheral portion of the constriction passage 3. Since the retainer neck elastically absorbs the force of expanding the stenotic passage 3 to assist the expansion of the stenotic passage 3, a buffer hole 6 is provided, so that when the retainer neck passes through the stenotic passage. The force received by 3 is soft The holes 6 are elastically absorbed, so that the retainer 10 can be guided with an extremely small force. Further, since the narrowed passage 3 is not worn or damaged when passing through the retainer, the diameter of the narrowed passage 3 is not expanded, and after passing through the retainer, the narrowed passage 3 is restored to its initial state by elasticity. As a result, the retainer 10 can be reliably prevented from moving to the guide hole 4 side and falling off thereafter.

[0010]

[Effect of device]

 As can be seen from the above description, the present invention can be performed very easily without requiring a large force to move the retainer from the retainer guiding portion to the retainer mounting hole, and the workability of mounting the retainer can be improved. The retainer can be remarkably improved, and the retainer can be reliably prevented from falling off during transportation after mounting.Furthermore, the retainer has the same basic shape as before, so no design changes etc. are required. It has many advantages such as being able to be used as is in conventional products without adding it. Therefore, the present invention is of great practical value as it eliminates the problems of the conventional retainer fitting.
