Description

[Detailed description of the invention] The present invention is suitable for joining two members that are easily exposed to vibration, such as an automobile door panel and a door lock, or an automobile pillar panel and a door lock striker. Regarding structure.

Conventionally, when attaching a car door lock to a door panel, the base plate of the door lock and It is known to interpose rubber packing between the door panel and the door panel, and to fasten them together using fasteners such as bolts.

However, in such a joint structure, the durability of the packing is relatively poor, and as the packing deteriorates, the vibration-proofing and sound-proofing effects are weakened, and the setscrews tend to loosen or become misaligned.

In addition, when joining both parts using such packing, the number of parts increases, and the positioning of the packing on the base plate of the door lock must be considered, making the assembly work complicated. be.

The present invention was made in view of the above-mentioned drawbacks of the conventional structure.
By flocking flexible short fibers, bringing the joining surfaces of both members into close contact with each other through the flocking, and tightening both members with appropriate tightening means, the rubber packing can be attached to both sides. It is possible to achieve the same soundproofing and vibrationproofing effects as when interposed between the joining surfaces of the members, the effect of preventing loosening of the tightening means, the effect of preventing the displacement of both members, etc., and the number of parts is small. Easy to assemble and durable 2.
The purpose is to provide a joining structure for members.

The present invention will be described below based on embodiments shown in the accompanying drawings.

1 to 3 show a first embodiment in which the present invention is applied to joining a door lock and a door panel of an automobile.

The door lock body 1 is assembled on a base plate 2, and this base plate 2 has screw holes 3a, 3b, 3c drilled at required positions, and is fixed at a specified position on the door panel 5 with screws 4a, 4b. It is something that will be done.

Joint surface 2 of base plate 2 with door panel 5
As shown in the enlarged view in FIG. 2, a is flocked with fine short fibers 6a made of flexible synthetic resin or the like. The length of the short fibers 6a is about 1 to 2 mm.

Such flocking 6 can be easily performed by a known electrostatic flocking method. That is, base plate 2
With the adhesive applied to the bonding surface 2a, the base plate 2 is charged with a positive or negative charge, and one end of the short fiber 6a charged with an opposite charge is attached to the adhesive. , can be planted almost perpendicularly and uniformly to the joint surface 2a.

Thus, the joint surface 2a of the base plate 2 with flocked hair 6 is brought into close contact with the inner surface of the door panel 5,
The door lock body 1 is attached to the door panel 5 with the flocked short fibers 6a buckled by tightening both members together with screws 4a and 4b.

Note that the details of the latch and other lock mechanisms attached to the door lock body 1 are not directly related to the present invention, and therefore will not be described.

In the embodiment with the above configuration, the two members to be joined to each other, that is, the base plate 2 and the door panel 5, have flocked hair on the joint surface 2a of the base plate 2.
After that, they are fastened with screws 4a, 4b, etc., so even with the flexibility of the flocked hair 6, both members 2,
It acts as a buffer between screws 4 and 5, which is caused by vibrations when the car is running or collisions with the striker when the door is closed.
There is no risk that a, 4b, etc. will become loose and the adhesion will deteriorate.

In addition, the operation noise generated when the door lock body 1 is opened and closed and the accompanying vibrations are also absorbed by the flocking 6 on the joint surface 2a.

Furthermore, since the base plate 2 of the door lock body 1 is pre-flocked 6, unlike the conventional joint structure, there is no need to prepare separate parts such as rubber packing, and the number of parts on the automobile assembly line is reduced. Can facilitate automation.

Furthermore, unlike conventional rubber packing, there is no risk of deterioration over time or deterioration of the packing's function.

FIGS. 4 and 5 show a second embodiment in which the present invention is applied to the joining of an automobile pillar panel and a door lock striker.

The door lock striker 7 has screw holes 8a, 8
It is fixed perpendicularly to a base plate 8 having a shape of 1.b, and is formed by flocking 10 flexible short fibers onto the joint surface 9 of the base plate 8.
This striker 7 connects the joint surface 9 of the base plate 8 with flocked hair 10 to the pillar panel 11 of the automobile.
It is joined to the pillar panel 11 by tightening screws 12a and 12b in close contact with the outer surface of the pillar panel.

By thus fastening the striker 7 to the pillar panel 11 via the flocking 10, it is possible to achieve the effect of preventing loosening due to vibrations of the automobile, the effect of soundproofing, the effect of damping vibrations, the effect of preventing displacement, etc.

Note that the present invention is not limited to the above-mentioned embodiments.
It is applicable to any joining structure in which members are brought into close contact with each other and fastened using screws or other fastening means.
