Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mounting device for a vehicle door lock.

Door lock cases for vehicles with internal door lock mechanisms have come to be integrally molded from resin for ease of production and rust prevention.
Since its strength is insufficient, it is attached to the door mounting plate by tightening screws together through a base plate made of a metal plate attached to its upper and lower surfaces.

However, the resin case tends to shrink if left in a tightened state for a long period of time, so the tightening screws may loosen and cause play in the mounting section, or the resin case may become deformed when tightened strongly. This has the disadvantage that it interferes with the operation of the internal door lock mechanism.

The purpose of the present invention is to improve this inconvenience, and is designed so that no tightening force is applied to the resin case even when the tightening screw is tightened.

To explain this with reference to the illustrated embodiment, in FIG. 1, reference numeral 1 indicates a resin case, and the case 1 is formed into a substantially rectangular shape, and has a fitting opening 2 on one side thereof into which a striker is fitted, and a metal plate on its upper and lower surfaces. Attach a base plate 3 made of
It is adapted to be attached to a mounting plate 11 of a door, which will be described later, by means of a tightening screw 5 inserted into a mounting hole 4 provided in the door. As shown in FIG. 2, the case 1 has a screw insertion hole 6 through which the tightening screw 5 is inserted.
is formed in a cylindrical shape, and the insertion hole 6 does not have the above-mentioned disadvantages because the wall thickness of the cylindrical body cannot be made large because of the recess 7 formed in the case 1 to house a locking mechanism (not shown). have Therefore, in the present invention, as shown in FIG. 3, a metal pipe 8 is inserted into the insertion hole 6, and the pipe 8 is formed on the upper base plate 3a by bending its top 8a into a brim shape. The lower part 8b thereof is formed in a horizontal plane and is brought into contact with the shaft cylinder 10 for engaging the tightening screw formed on the base plate 3b on the lower surface,
Thus, when attaching to the mounting plate 11 of the door, the top 8a of the pipe 8 is held between the back side of the dish-shaped mounting hole 12 formed in the mounting plate 11 and the countersunk hole 9 formed in the base plate 3a on the upper surface. It is attached using tightening screws 5 as shown in the figure.

In this way, according to the present invention, the resin case 1
A metal pipe 8 is inserted into the insertion hole 6 for the tightening screw formed in the hole 6, and both ends of the pipe 8 are held between the base plates 3a and 3b attached to the upper and lower surfaces of the case 1. Since the tightening force is supported by the pipe 8 and the base plates 3a and 3b and does not act directly on the insertion hole 6 of the case 1, the case can be firmly attached without being damaged even by a large tightening force. Since the insertion hole 6 does not require reinforcement during molding, the case can be made smaller by forming the part thinner, and even if the case is deformed due to resin sink etc., the mounting part will not play, etc. It has the effect of
