Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention is intended to improve the peeling strength of a sealing member provided on a surface of a body of a door lock body that abuts a side wall of an inner panel of a door. The present invention relates to improvement of a door lock device for an automobile.

[Conventional technology]

In a general door lock device having a structure to be attached to an inner panel of a door, as shown in FIG. 4, an inner side wall (c) of an inner panel (b) in a body (a).
A surface that abuts, that is, formed on the body (a),
A soft sealing member (d) such as a sponge is adhered to the opening edge of a guide groove (not shown) through which the striker on the vehicle body side enters, so that raindrops or the like that have entered through the guide groove or the like can be applied to the door lock body. It prevents the lock mechanism side from entering and leaching to the door trim side (see Japanese Utility Model Laid-Open No. 50-95708).

[Problems to be solved by the device]

Adhesion of the sealing member (d) to the body (a) is often easily performed with a double-sided adhesive tape or the like.

In such a case, if oil or dust adheres to the adhesive surface in the manufacturing or assembly process, adhesive failure will occur, and the adhesive end parts may collide with each other during box packaging, transportation, or assembly to the door. (E) was easily peeled off, which was a problem in terms of waterproofing.

In order to prevent this, it is necessary to use an adhesive having high adhesiveness that is not affected by oil or the like.

However, the use of such an adhesive not only complicates the bonding work, but also increases the cost of the adhesive and raises the manufacturing cost. Therefore, an alternative simple and inexpensive mounting means is required. ing.

The present invention has been made in view of the above problems, and can be easily attached to a conventional door lock device without changing the design, and can improve peeling strength after attachment and enhance waterproofness. An object of the present invention is to provide an automobile door lock device that can be used.

[Means for solving the problem]

In order to achieve the above object, the present invention provides a body for a door lock body, a cover plate provided at a rear end of the body is in close contact with a rear wall of an inner panel of the door, and is provided on a side portion of the body for entering a striker. In the door lock device for an automobile, a sealing member having a substantially rearward U-shape provided at the opening edge of the guide groove is fixed to the inner panel of the door so as to be in close contact with the side wall of the inner panel. Both ends of the sealing member on the cover plate side are formed to have a required dimension so as to project from the rear end of the body to form free ends, and the free ends are sandwiched between the rear end of the body and the cover plate, and other It is characterized in that the portion is bonded to the opening edge portion of the guide groove by an appropriate bonding means.

[Action]

According to the present invention, both free ends of the sealing member, which are most easily peeled off, on the cover plate side are concealed and strongly held by the rear end of the body and the cover plate, so that the peeling strength of the entire sealing member can be increased. .

Further, since the free end portion can be easily clamped at the same time when the cover plate is attached, workability is improved.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS.

In FIGS. 1 and 2, the door lock body (1)
Is a synthetic resin body (3) to which a latch (2), a pole (not shown) and the like are assembled, and a base plate (4) integrally formed on the front side (left side in the figure) of the body (3). The locking / unlocking mechanism (8) is provided with a knob lever (5), an inside lever (6), an outside lever (7), and the like.

(9) is a cover plate fixed to the rear surface of the body (3), and the door lock body (1) has a guide groove (10) formed in the body (3) for entering a striker, The cover plate (9) is aligned with a guide groove (not shown) for entering the striker formed in the rear wall (11a) of the inner panel (11), and the cover plate (9) is attached to the rear wall (11a) of the inner panel (11). It is attached by fixing to.

At the opening edge of the guide groove (10) of the body (3) for entering the striker, a soft sealing member (12) formed in a rearward U shape with a foam material such as butyl rubber or sponge is provided on the body (3). Both free ends on the cover plate (9) side, which are formed to be slightly longer than the rear end, are sandwiched between the rear end of the body (3) and the cover plate (9), and the other end It is attached by applying an adhesive or by sticking a double-sided adhesive tape or the like (see FIG. 3).

When the door lock body (1) is assembled to the door (D), the sealing member (12) comes into close contact with the inner side wall (11b) of the inner panel (11) and enters through the guide groove (10) or the like. Incoming raindrops and the like are prevented from entering the locking / unlocking mechanism (8) and the door trim (not shown) side.

As described above, in the door lock device of the above-described embodiment, both the free ends of the sealing member (12) on the cover plate (9) side are strongly held at the same time as the cover plate (9) is attached without being adhered. Therefore, unlike conventional adhesive-only adhesives, there is no risk of peeling of the ends during packaging or during transportation, and the waterproofness can be further enhanced.

Further, the conventional door lock device can be easily attached without any design change, and has sufficient peel strength without using an expensive adhesive, which impairs workability and increases manufacturing cost. Nothing.

[Effect of device]

According to the present invention, the peeling strength of the entire sealing member can be increased by integrally sandwiching both the free end portions of the sealing member on the side of the cover plate where peeling is most likely to occur with the rear end of the body and the cover plate. it can.

As a result, it is possible to provide a door lock device that can be manufactured at low cost without using an expensive and cumbersome adhesive and has high reliability in waterproofness.
