Description

[Detailed description of the invention] The present invention is applicable to, for example, a weather strip that is fixed along the opening edge of a car window, or a rubber cushioning material provided to cushion the impact of a door. It relates to a device for smoothly and reliably attaching the device to a panel portion forming a panel.

Normally, weather strips and rubber cushioning materials are integrally formed with locking legs that expand in diameter from the main body, and these locking legs are inserted into holes prepared in the panel. The swollen diameter portion, which expands and returns to its original shape after passing through, prevents its removal and is used for installation.However, since this locking leg is flexible like the main body, Even if it is possible to reduce the diameter, it is not easy to insert the weather strip into the hole by pushing it, and in the case of weather strips having many locking legs, this poses an obstacle to work efficiency.

In addition, since the locking legs of this type of member are soft, it is difficult to confirm even if the locking legs expand again after passing through the hole and lock on the opposite side of the panel, and therefore it is usually difficult to visually check the individual locking legs. It was a hassle to proceed with the work while checking the insertion state of the locking leg.

On the other hand, despite this difficulty in mounting, the locking leg mounted in the hole had a major defect in that it was weak against withdrawal and would fall off with a withdrawal force smaller than the insertion force.

The present invention was devised in view of these points, and the main body of the clip formed in a cylindrical shape is fitted into a flexible insertion leg that is provided integrally with the main body part such as a weather strip. The inner locking piece provided on the cylindrical wall of the main body is fitted by locking it to the engaging leg, while the main body of the clip is inserted into the hole provided in the panel, and the outer locking piece provided on the cylindrical wall is inserted into the hole. An object of the present invention is to provide a mounting device which can be latched onto the edge of a panel, thereby allowing a locking leg made of a soft material to be quickly and reliably mounted in a hole in a panel.

More specifically, the present invention provides a clip main body with a flexible inner locking piece, so that the flexible locking leg can be easily inserted into the main body, and the upper inner locking piece is inserted simultaneously with the insertion. While securing the latch-fitting state, the clip body is directly inserted into the hole of the panel, and the outer locking piece provided thereon is hooked to the edge of the hole and cannot be removed, thereby completing the installation of the locking leg. This method avoids the difficulty of passing the locking leg made of soft material such as rubber directly through the hole in the panel, and achieves an accurate locking condition. It is an object of the present invention to provide a mounting device that allows the user to confirm the locked state and proceed with the work based on the feeling of mounting provided by the snapping sound that is emitted when the device passes through and engages.

Hereinafter, the embodiments illustrating the present invention will be described in more detail. Figure 1 is a front view of the right half of the clip 1 according to the present invention in cross section, Figure 2 is a bottom view, and Figure 3 is a clip made of synthetic rubber. FIG. 4 is a partially sectional front view showing a state immediately before the locking leg 3 extending integrally from the weather strip 2 is attached, and FIG. 4 is a partially sectional front view showing the attached state.

The clip is made of a thermoplastic synthetic resin such as nylon and has a cylindrical main body 1a.Here, the main body 1a is shaped like a short cylinder, and one opening end 4 of the clip has a hole formed in the outer peripheral surface of the panel 5, which will be described later. A flange part 7 is provided to regulate the amount of insertion into the part 6, and a pair of inner locking pieces 8, 8 and outer locking pieces 9, 9 are provided on the cylindrical wall of the main body, each pair facing the center of the main body. is provided.

The inner locking piece 8 is for locking the locking leg 3, and has a U-shaped notch in the cylindrical wall, the proximal end is provided on the open end 4 side, and the free end is tongue-shaped with the free end facing the other open end 10 side. It is formed as a piece, and the inner surface of its free end is provided with a locking pawl 8a that projects toward the center of the main body.

On the other hand, the outer locking piece 9 is for hanging the main body of the clip in the hole 6 of the panel, and is cut into a tongue shape by two slits 11 cut vertically from one opening end, and a free end is attached to the opening end. It is set so that it is facing the direction. The free end of this outer locking piece projects outward, and a locking claw 9a facing the flange 7 is provided at the tip.

The clip main body 1a is formed to have a diameter that matches the outer diameter of the locking leg to be attached, in this embodiment, the locking leg 3 of the weather strip 2, so that the locking leg can be inserted into the hollow interior. During this insertion, the claw 8a of the inner locking piece is inserted into the expanded diameter portion 3a provided on the locking leg.
is once pushed outward and then hooked onto the reversely tapered jaw 3b to secure it to the locking leg.

On the other hand, the panel 5 here is the opening edge of a car window, and the hole 6 is a round hole with a diameter matching the outer diameter of the clip main body 1a so that the clip main body fixed to the engaging leg 3 can be inserted. There is.

The present invention is constructed as described above, and the hole 6
To attach the locking leg 3 to the clip, first pass the clip main body 1a through the flexible locking leg 3 as described above.
After expanding the inner locking piece 8 outward with the expanded diameter portion 3a provided on the locking leg, the locking claw 8a is hooked onto the inclined surface of the reversely tapered jaw 3b, and the locking leg is fitted into the locking leg. complete.

At this time, as shown in the figure, it is possible to provide a bar-shaped guide part 12 at the tip of the locking leg 3, pass it through the main body of the clip first, and then pull out the tip to make it pass through the expanded diameter part more quickly. It is possible to perform proper fitting. Of course, this guide part becomes an unnecessary part after installation, so if it interferes with installation to the panel, it can be cut and removed.

After fitting the clip main body to the locking leg 3 in this way, when it is pushed into the hole 6 of the panel, the clip main body is molded to match the diameter of the hole, and the rigidity of the synthetic resin material. The main body of the clip easily slides in, bends the outer locking piece 9 inward at the edge of the hole, passes through this and engages the locking claw 9a with the edge, making it impossible to pull out. It is locked. Of course, at this time, the flange portion 7 comes into contact with the front edge of the panel 5 and is held and fixed from the front and back in cooperation with the locking claws 9a.

In this way, the present invention fixes a flexible locking leg to the hole in the panel, and in addition to making it easy to attach the clip main body to the hole 6, it also makes it easier to fit the clip main body into the locking leg 3. This can be done easily by pushing the tongue-shaped inner locking piece 8 outward, which makes it much easier to install than the conventional method of attaching flexible locking legs directly to the hole in the panel. , the locking leg receives the locking claw 8a of the inner locking piece 8 that bends inward in its jaw and stops so that it cannot be pulled out, and the locking claw 9a of the outer locking piece 9 locks in the hole of the other panel. Since the locking leg is installed in such a way that it is installed in a manner that is much more secure than the conventional installation method that uses the expansion and contraction of the enlarged diameter portion of the locking leg to lock into the hole in the panel, a much more secure installation can be achieved.

Moreover, in actual work such as installing a weather strip, it is difficult to confirm that the locking leg is locked in the condition where it is difficult to see how far the locking leg is inserted into the hidden hole on the back of the main body. This was a major obstacle in terms of work efficiency, but in this invention, when the clip is attached to the hole, the outer locking piece, which is bent inward once the clip is pushed in, snaps onto the edge of the hole using elastic restoring force. It has the advantage of being easy to check and greatly increasing work efficiency because it gives a comfortable fit.

In the embodiment, the main body of the clip is cylindrical, but the shape should be selected according to the locking leg to be attached.For example, if the cross section of the locking leg is square, the shape should be selected to match the shape. It can be made into a cylindrical shape.

Further, although the inner and outer locking pieces 8, 9 are provided in pairs in each of the embodiments described above, it goes without saying that the number is not limited to this, and the number may be three or four.

In addition, as in the illustrated embodiment, the inner locking piece 8 is a tongue-shaped piece that projects from the insertion side opening end 4 of the engagement leg toward the other opening end 10, and the outer locking piece 9 is turned in the opposite direction. Providing an extending tongue-like piece is effective in improving the ease of attachment to the engaging leg and the hole in the panel, and increasing the locking force.
