Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening / closing lid locking device.

[0002]

2. Description of the Related Art As a simple opening / closing lid lock device for closing an opening of a console or a glove box of an automobile, a base member 1 fixed to a console or the like, as shown in FIG. And a knob 5 that is rotatably connected to the knob.
The knob 5 has a hook portion 2 and a hook portion 4 protruding from the back surface of the hand portion 2, and the closed state is maintained by locking the hook portion 4 to a striker (not shown) on the console side.

However, in the above-mentioned conventional example, the knob 5 is formed by integrally forming the handle portion 2 and the hook portion 4 and generally has the same surface treatment. Therefore, for example, when the handle portion 2 is plated, The hook 4 also has a metallic luster,
There is a drawback that when the opening / closing lid is opened, the design harmony with the back surface of the opening / closing lid is not remarkably achieved.

[0004] In order to solve such a drawback, for example, as disclosed in Japanese Utility Model Publication No. 3-39581, a handle 2 is used.
It has also been proposed to mount an outer skin body that has been subjected to a plating process on the surface of the body. The lock device described in this publication includes a body having a lock lever biased upward by a spring, a knob body rotatably supported by the body, and a skin mounted on the outer surface of the knob body. Is done. An operation lever is protruded from the knob body, and when the knob body is rotated around a support shaft in an unlocked state, the lock lever can be lowered into the body via the lever.

The outer body is mounted on the knob body by engaging the engaging body and the engaging portion with the knob body. In the mounted state, the elastic tongue formed on the knob body engages the engaging body. Pressing in the direction prevents separation.

[0006] This conventional example has an advantage that plating can be applied only to a handle portion of a knob or an arbitrary color can be applied only by preparing an outer cover having a desired surface treatment or the like. However, it has the following disadvantages.

In other words, since the outer cover body elastically deforms the engaging body and the engaging portion to resiliently engage with the handle portion of the knob body, the plating film or the coating film of the outer cover body is cracked during the mounting operation. , Peeling easily occurs. Also, in order to make the outer skin resiliently engage with the knob body, the outer skin must be formed of a synthetic resin material, but the types of plating films that can be formed on the surface of the synthetic resin material are limited. However, there is a disadvantage in that it generally lacks a solid feeling.

[0008]
