Description

[Detailed description of the invention] [Industrial application field] The present invention relates to the structure of the mounting part of automobile interior parts.
More specifically, the present invention relates to a structure for attaching an automatic transmission shift knob and other handles.

[Conventional technology and issues] Conventionally, automatic transmission shift knobs and other handles, such as parking brake handles and door latch knobs, have been made of plastic to meet the trend toward luxury, and to improve the aesthetics of interior design and the feel when touched. Instead of using the body as is, it has come to be used by covering it with soft skin such as PVC leather or real leather.

However, in the case of genuine leather wrapping, which is considered to be the best choice for high-end products, it generally has less elasticity than PVC leather, so it tends to be difficult to finish the mounting part aesthetically, which has been a problem in processing.

Specifically, it is as follows.

A cross-shaped cut was made in the skin and a plastic molded body was basically screwed on, leaving half of the screw head covered. This inevitably resulted in poor appearance, and since the handle was frequently touched, the skin was more likely to peel off from this area.

In the method of making a cross or larger cut in the skin and gluing it to the inner wall of the recessed screw hole, it takes time for the adhesive to harden, and if it accidentally peels off and hardens, it becomes impossible to remove the screw.

In the method of pressing the skin with a screw with an inverted conical head as shown in Figure 13, the screw holes could not be made deep, resulting in poor appearance and the screws tended to loosen due to "sagging" of the skin. . This is because the shift knob is simply fixed to the base (lever) with two screws, and a load is applied each time it is used. However, if I tightened the screws too tightly, the epidermis would break.

It was considered to cover the screw hole with a separate material, but
It has not been adopted because it increases costs and has poor workability.

As shown in Fig. 14, a method of pressing the skin with a washer 9 and fixing it with the protruding screw head 3A was considered, but it was not adopted because it looked bad, interfered with operation in the handle, and had a bad feel. Ta.

Note that FIGS. 12, 13, and 14 are an external view, a cross-sectional view, and a cross-sectional view, respectively, of a conventional mounting portion.

As a result of various studies, the present inventors came up with the idea of fixing the skin end by inserting a radially expanded and biased ring member into the inner wall of the sunken screw hole, and finally completed the present invention.

[Purpose of the invention] The purpose of the invention is to ensure that the soft skin wrapping part does not peel off easily, the skin does not get in the way when screws are attached and removed, and the handles have a good feel and can be used for a long period of time. .

Another object of the present invention is to properly and reliably dispose of the soft skin-wrapped portion when covering an automobile interior parts handle made of a plastic molded body with a soft skin and screwing it onto a base body.

[Structure of the invention] According to the invention, the surface of the plastic molded body is covered with a soft skin,
In a structure for attaching an automobile interior part to a base body with screws, a recessed screw hole is provided in a plastic molded body, the skin is wrapped around the inner wall of the screw hole, and the skin wrapped part is expanded and the screw hole is inserted into the screw hole using a biasing ring member. A mounting structure for an automobile interior part is provided, which is characterized by being press-fixed to an inner wall.

The present invention will be explained in detail below using examples.

[Embodiment] FIG. 10 is a front view of an automatic transmission shift knob including an embodiment of the present invention, and FIG. 11 is a sectional view taken along the line -' in FIG. 10.

10 and 11, 1 is an automatic transmission shift knob, 2 is a base body (shift lever), 3 is a sinking screw (screw), 4 is a sinking screw hole (screw hole), 5
6 is a plastic molded body, 6 is a push button, 7 is a soft skin, and 8 is a skin wrapping part.

Figures 1, 2, and 3 are cross-sectional views of the embodiments of the present invention, and Figures 4, 5, 6, 7, 8, and 9 are cross-sectional views of the embodiments of the present invention. FIG. 3 is a perspective view of an embodiment of an expanded biasing ring member that is part of the .

FIGS. 1 and 2 show that the soft skin 7 is
The figure shows a cross-sectional state in which the winding portion 8 is pressed and fixed to the inner wall 4A of the sunken screw hole 4. Figures 4 to 9
The ring member shown in the figure can be made of hard plastic such as hard PVC or metal such as steel, A1 alloy, or Cu alloy. These are cut from pipe or individually molded. In the case of FIG. 4 and FIG. 7, there is no cut 11 in the ring member itself, but if the outer diameter of the ring is made slightly larger than the inner diameter of the skin-wrapping portion of the hole 4, the skin-wrapping portion 8 can be cut as a result. It will be expanded and biased so as to press against the inner wall 4A. In other cases, since there is a cut 11, the elastic force is applied to expand with a large stroke in the radial direction. In particular, in the case of ring members such as those shown in FIGS. 7, 8, and 9, the screw head is tapered in the direction of the screw axis (it may or may not be tapered) as shown in FIG.
Since the bottom portion 10A is fixed under pressure, the fixation of the ring member and the skin wrapping portion becomes even more reliable.

[Effects of the invention] By implementing the invention, all of the above objectives are achieved. That is, the soft skin wrapped portion does not peel off easily, the skin does not get in the way when screws are attached and removed, and the handles feel good and can be used for a long period of time.
