Description

Recyclable Car Steering Wheel

The present invention relates to a recyclable automobile steering wheel, and more particularly, to improve the configuration of the steering wheel for easy reuse and replacement of resources.

The steering wheel, which the driver grips and operates in the steering system of the automobile, is usually configured as a rim portion that is a circular handle portion and a hub-shaped spoke portion that connects the rim portion and the central boss portion;

Each of these components is a single component, and is molded by inserting the insert, which is a basic metal plate processed body, in the inside thereof.

Therefore, there is a problem in that only the rim portion cannot be detached from the boss portion, and thus, when any one of the constituent members is broken, the whole must be replaced;

The inner part of the rim has a structure that cannot be recycled, such as preventing the plastic part from being recycled due to the insert being inserted.

In addition, since the rim cannot be detached from the boss part, only a single monotonous handle should be used until the disposal of the vehicle. Therefore, in the case of a car enthusiast who likes a variety of decorations, the entire steering wheel is replaced, which wastes a lot of resources. And the like.

Recyclable automobile steering wheel of the present invention, in view of the problems of the conventional configuration described above, the rim portion is easily separated from the boss portion to enable replacement of the rim portion of various shapes and colors;

It is an object of the present invention to provide a recyclable automobile steering wheel having a configuration that enables a reduction of costs by allowing only a part to be replaced in the event of a breakage of a part, and the recycling of resources at the time of disposal.

The configuration of the recyclable automobile steering wheel of the present invention together with the accompanying drawings will be described in detail.

1 is a plan view of a steering wheel constituted by a recyclable automobile steering wheel of the present invention, FIG. 2 is a plan view of an insert of a wheel rim part, FIG. 3 is a plan view of an insert of a boss part and a spoke part, and FIG. 4 is a view of FIGS. A plan view of the insert assembly in the assembled state of the drawing member, FIG. 5 is a sectional view taken along line CC of FIG. 4, FIG. 6 is a sectional view taken along line AA of FIG. 1, and FIG. 7 is a sectional view taken along line BB of FIG. .

The steering wheel SH shown in FIG. 1 connects the wheel rim portion 10 and the boss portion 20 and the wheel rim portion 10 and the boss portion 20, which are the outer grip portions, and above the horn. The spoke parts 30 having push buttons 31 and 32 are roughly configured.

Since the wheel rim portion 10, the boss portion 20 and the spoke portion 30 of the steering wheel SH should be an injection molded body having considerable rigidity, it is usually a metal plate processed body having basically each shape inward. Inserts are molded by inserting them.

2 shows an insert for use in the steering wheel of the present invention.

As shown, the rim insert 10 'of the wheel rim 10 has a circular cross section, a whole flat shape, a large diameter circle, and a plurality of connecting ribs 11 for connection to the inner boss portion 20. It is a metal plate body processed by the furnace.

The cross-sectional shape of the rim insert 10 'is shown in Figure 6 for the purpose of describing later;

It is configured as a reinforcing rim portion 12 and a reinforcing plate portion 13 connected to the reinforcing rim portion 12 and the reinforcing plate portion 13 is half the diameter D of the entire wheel rim portion 10 with respect to the reinforcing rim portion 12. It is assumed as the length of the degree.

The core insert 40 as shown;

The plurality of rib pieces 33 constituting the spoke portion 30 and the boss plate portion 21 constituting the boss portion 20 in the center in cooperation with the connecting rib 11 of the rim insert 10 ' Integrally formed;

A fastening hole 11 'and a fastening hole 33' for fastening the bolt B are drilled at the end of the rib piece 33, respectively.

As in the conventional configuration, the pushbuttons 31 and 32 of the horn are pushbuttons 11 ', which push the ribs 33 and the connecting ribs 11 into bolts B as pushbuttons 31 and 32. 33 ') constitute a position to conceal the site;

As shown in FIG. 7, the pair of fastening pins 34 'protruding downward from the push buttons 31 and 32 are opened in both directions to press-fit the fastening pins 34' of the rib piece 33. Insert and tighten).

In order to realize the object of the recyclable automobile steering wheel of the present application, as described above;

Outline of the cross-sectional shape of the rim insert 10 ' It is configured as a reinforcing plate portion 13 and the reinforcing plate portion 13 connected to the reinforcing rim portion 12;

The reinforcing plate portion 13 has a length that is about half the diameter D of the entire wheel rim portion 10 with respect to the reinforcing rim portion 12, so that the end portion 13 'of the reinforcing plate portion 13 almost changes the wheel rim portion 10. To be connected to the end of the injection filler (G) constituting.

The configuration, use, and recycling of the steering wheel of the present invention of the above-described configuration will be described.

In order to configure the steering wheel SH, the rim insert 10 'and the core insert 40 are fastened to the rib piece 33 and the connecting rib 11 by a bolt B and injection molded in this state to inject injection filler ( G) configure the entire wheel;

The push buttons (31,32) are injection molded to open the portion of the fastening holes (11 ', 33') for fastening the rib piece (33), which is the pushbuttons (31,32) of the horn, and the connecting rib (11) to the bolt (B). A pair of fastening pins 34 'protruding downward) is inserted into the fastening holes 33' of the rib piece 33 and assembled.

By releasing the push buttons (31, 32) of the horn by the configuration as described above;

Rib pieces 33, which are push buttons 31 and 32 of the horn, and fastening holes 11 'and 33' for fastening the connecting ribs 11 are opened to release the bolts B and other shapes. By replacing and mounting various wheel rims 10 having shapes and colors, the applicability is increased, and only the damaged parts can be replaced.

Also in the wheel rim portion 10 having most of the injection filler (G);

The rim insert 10 'is configured as a reinforcing rim portion 12 having a circular cross section and a reinforcing plate portion 13 extending from the reinforcing rim portion 12, wherein the reinforcing plate portion 13 is formed as a whole wheel rim with respect to the reinforcing rim portion 12. Part of the injection filler (G) side where the end portion 13 'of the diameter D of 10) meets (in fact, the reinforcing plate portion 13 extends to the end face, so no incision is necessary);

Injection filling material (G) of the rough cross-sectional shape can be easily separated from the reinforcing rim portion 12, so that the plastic and metal parts can be separated and recycled.

The recyclable automobile steering wheel of the present invention having the above-described configuration is a useful design that increases the degree of recycling of resources and increases the convenience of driving by easily removing various types of wheel rims.
