Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to an improvement in a clip for fixing, for example, two panels to each other or a panel and a decorative material to each other.

``Prior art'' As a conventional clip of this type,
There is one shown in Publication No. 12710.

Although not specifically shown, the conventional clip is an integrally molded product made of synthetic resin, and consists of a head part that holds the panel and legs that engage the mounting holes of the panel. For this purpose, the shape is made into a hollow rugby ball shape with elasticity, and a plurality of slits are opened in the peripheral wall of the hollow rugby ball shaped legs, and between each slit there are elastic holes that are fixed to the mounting holes of the panel. The structure is such that locking wall portions are defined intermittently.

When actually fixing two panels, first, the head of the clip holds the edge of the mounting hole drilled in the other panel, and then The mold legs are inserted into the mounting holes drilled in one panel side, and the plurality of elastic locking walls defined between the slits of the legs are locked to the edges of the mounting holes. In other words, the two panels will be fixed together.

``Problem to be solved by the invention'' However, in the case of conventional clips, if slits are formed in the peripheral wall of the hollow rugby ball-shaped legs and an elastic locking wall is defined between the slits, the problem arises. This elastic locking wall part itself is simply defined by using a hollow rugby ball-shaped surrounding wall that lacks rigidity, so even if
Even if the upper and lower ends of each elastic locking wall are connected, the elastic locking force against the mounting hole will naturally weaken, and if an unexpected external force is applied to the clip, the panels will unintentionally wobble together. This had a major problem in that it could not be fixed stably.

For this reason, conventionally, by increasing the thickness of the peripheral wall of the hollow rugby ball type leg and increasing the diameter difference between the inner diameter of the mounting hole and the maximum outer diameter of the leg,
It may be possible to solve the above problems to some extent, but this time, not only will it be difficult to insert the legs into the mounting holes, but the outer circumferential surface of each elastic locking wall will not fit into the mounting holes. Problems such as scraping at the edge of the hole and the impossibility of repeated use arise.

``Means for Solving the Problem'' The present invention was developed to effectively solve the problems of conventional clips, and includes a head that holds the panel and a mounting hole of the panel. A pair of parallel rigid walls are provided in the portions of the legs excluding the distal ends thereof, and one end edge of the one rigid wall and both end edges of the other rigid wall are connected to each other. , three elastic locking walls arranged at equal angles on the same arc trajectory are integrally formed, and one of the two elastic locking walls formed on the other rigid wall side is rigid. The tip of the elastic locking wall located on the other edge of the wall,
The three elastic locking walls are separated from the other end edge of one rigid wall through a slit to provide the same bending function, while the outer peripheral surfaces of the three elastic locking walls have the above-mentioned rigid A configuration is adopted in which an arc-shaped press-contact part is formed that elastically engages the edge of the mounting hole with a reaction force obtained from the wall.

``Function'' Accordingly, in the present invention, when the arc-shaped press-contact portions of the three elastic locking walls lock into the mounting holes of the panel, in addition to the elastic force of the elastic locking walls themselves, the rigidity Since it is possible to actively utilize the reaction force obtained from the wall as a locking force, it is possible to significantly increase the elastic locking force against the mounting hole of the panel compared to conventional clips. .

Therefore, even if an unexpected external force is applied to the clip, there is no need to worry about the panels inadvertently rattling each other, as was the case in the past, and a secure fixation is always guaranteed. This will also improve your sex.

``Example'' Hereinafter, the present invention will be described in detail based on an example illustrating the present invention.The clip according to this example is also an integrally molded product of synthetic resin, and has a panel as shown in FIGS. 1 and 2. It is composed of a head portion 11A that holds the panel, and leg portions 11B that lock into the mounting holes of the panel.

The head 11A holding the panel is connected to the neck 1
It has a sealing flange 13 and a holding flange 14 which are spaced apart from each other via 2, and both flanges 13,
A movable flange 15 is further provided between the movable flange 15 and the holding flange 14, so that the panel can be held between the movable flange 15 and the holding flange 14 according to its wall thickness.

In addition, the leg portion 11B that locks into the mounting hole of the panel is
A pair of parallel rigid walls W1 and W2 that hang down integrally from the central lower surface of the seal flange 13 is provided at a portion other than the tip 16, and the one rigid wall W1
1 whose outer peripheral surface has an arc shape in the longitudinal direction of one end edge of the
Two elastic locking walls 17a and 17c, each of which has an arcuate outer peripheral surface, are integrally formed in the longitudinal direction of both ends of the other rigid wall W2. , the three elastic locking walls 17
a, 17b, and 17c are arranged at equal angles (120°) on the same arc locus, and the other rigid wall W2
Among the two elastic locking walls formed on the side, the tip of the elastic locking wall 17c located on the other edge side of the one rigid wall W1 is connected to the other edge of the one rigid wall W1 and the slit 18.
The three elastic locking walls 17 are separated through the
A, 17b, and 17c are configured to have the ability to bend in the same manner through the hollow portions 19 on their inner surfaces.

In addition, these elastic locking walls 17a, 17b, 17c
The upper edge portion is connected to the lower surface of the seal flange 13 in the same way as the upper edges of the rigid walls W1 and W2,
The lower edge portion is connected to the lower end portion 16 of the leg portion 11B.

In addition, in this embodiment, as shown in the figure, three elastic locking walls 17a, 17b, 17c are provided.
A configuration is adopted in which an arcuate press-contact portion 20 is formed on the outer circumferential surface of the mounting hole to elastically engage the edge of the mounting hole with a reaction force obtained from each of the rigid walls W1 and W2.

Therefore, when fixing two panels P1 and P2 using a clip having such a configuration, first insert the leg portion 11B into the mounting hole H1 of one panel P1, and check the rigidity of the leg portion 11B. If the three elastic locking walls 17a, 17b, 17c formed on the walls W1, W2 are allowed to pass through the mounting hole H1 while bending equally inward, each elastic locking wall 17a, 17b, 17
c returns to its original shape after passing through, and each arcuate press-contact part 20 is elastically engaged with the hole edge of the mounting hole H1 of one panel P1 with a surface press-contact state that is always slightly bent inward. Stop.

Therefore, after that, if the hole edge of the Daruma-shaped attachment hole H2 of the other panel P2 is held between the holding flange 14 and the movable flange 15 of the head 11A, as shown in FIGS. 3A and 3B.
As shown in the figure, the two panels P1 and P2 are fixed to each other.

In addition, when fixing these panels P1 and P2,
As in the past, first attach the other panel P2 to the head 11.
It goes without saying that a similar fixed state can be obtained even if the leg portion 11B is held at the position A and later engaged with the mounting hole H1 of the first panel P1.

However, in this embodiment, as mentioned above,
A pair of parallel rigid walls W1 and W2 are provided at a portion of the leg 11B excluding the tip 16, and each rigid wall W
1, W2, three elastic locking walls 17a, 1
7b, 17c, when the arcuate pressure contact portion 20 of each elastic locking wall 17a, 17b, 17c locks with the hole edge of the mounting hole H1 of panel P1, the shape of the locking wall itself In addition to elastic force obtained from The power will be effectively increased.

Moreover, these three elastic locking walls 17a, 17
b and 17c are arranged at equal angles on the same arcuate locus, which not only increases the number of points of contact with the hole edge of the mounting hole H1, but also increases the number of contact points with the hole edge of the mounting hole H1 compared to the anchor-shaped legs known in the art. Since it is brought into uniform pressure contact with the hole edge of H1, a uniform locking force for the mounting hole H1 can also be obtained.

Therefore, if the clip of this embodiment is used, even if an unexpected external force is applied to the clip, the panels P1 and P will not close due to insufficient locking force as in the conventional case.
Since there is no chance of the two members inadvertently shaking each other, a secure fixed state is always guaranteed.

In addition, in this embodiment, using the reaction force obtained from the rigid walls W1 and W2 as the locking force makes it possible to reduce the diameter difference between the inner diameter of the mounting hole 1 and the maximum outer diameter of the leg portion 11B. Even if it is as small as possible, the panel P1 is always reliable,
Since the fixed state of P2 is guaranteed, there is no fear that the outer peripheral surfaces of the elastic locking walls 17a, 17b, 17c will be scraped off, and the clip itself can be used repeatedly. In this embodiment, even though the locking force for the mounting hole H1 has been significantly increased, if it becomes necessary to pull out the leg portion 11B of the clip from the mounting hole H1 of one panel P1. In this case, if the elastic locking walls 17a, 17b, 17c are easily bent inward due to the arcuate shape of the pressure contact portion 20, the elastic locking walls 17a, 17b, 17c are easily bent inward by simply pulling out with a force that overcomes the reaction force described above. Since it can be pulled out smoothly from the mounting hole H1, each elastic locking wall 17 can be removed not only when inserted, but also when pulled out.
There is no fear that the arcuate pressure contact portions 20 of a, 17b, and 17c will be scraped or damaged and become unusable.

"Effects of the Invention" As described above, the clip according to the present invention has three elastic locking walls arranged at equal angles on the same circular arc trajectory with respect to a pair of parallel rigid walls. Therefore, when the arc-shaped pressure contact portion of each elastic locking wall locks into the mounting hole of the panel, the elastic force obtained from the rigid wall is obtained in addition to the elastic force of the elastic locking wall itself. Since it is possible to actively utilize reaction force, compared to conventional clips,
It has become possible to significantly increase the elastic locking force against the mounting hole.

Therefore, with the present invention, even if an unexpected external force is applied to the clip, there is no need to worry about the panels inadvertently shaking each other, as was the case in the past, and a secure fixed state is always guaranteed. Not only,
Along with this, watertightness can also be improved.

Moreover, in addition to the elastic force of the elastic locking wall itself, using the reaction force obtained from the rigid wall as a locking force makes it possible to reduce the difference in diameter between the inner diameter of the mounting hole and the maximum outer diameter of the leg. Therefore, not only is it easy to insert the leg into the mounting hole, but there is no fear that the outer peripheral surface of each elastic locking wall will be scraped off, and the clip itself can be used repeatedly.
In addition, in the case of the present invention, even though the locking force can be increased, when the leg of the clip is pulled out from the mounting hole of the panel, it is necessary to simply pull it out with a force that overcomes the reaction force etc. mentioned above. , each elastic locking wall easily bends inward due to the arc shape of its press-contact portion, and can be pulled out smoothly from the panel mounting hole, so that the arc-shaped press-contact portion of each elastic lock wall There is no fear that it will be scraped or damaged and become unusable, making it extremely effective for repeated use.
