Description

[Detailed Description of the Invention] The present invention relates to a catch adjusting device, which allows the position of the abutting portion between the door lock latch and the catch to be freely adjusted.

Conventionally, with door lock seats, if the mounting position is incorrect or the door is deformed, the gap between the latch and the hole increases, causing the door to rattle, or conversely, the gap may become large. There was an inconvenience that the latch became smaller and the latch would not fit.

For this reason, various catches have been proposed in the past in which the position of the abutting portion of the latch can be adjusted, but these have had drawbacks such as complex structures and the possibility of misalignment during use even after adjustment.

The purpose of this invention is to focus on the above-mentioned drawbacks of the conventional methods, and to provide an excellent product that has a simple structure, allows adjustment of the abutment part with the latch, and also ensures that no misalignment occurs after adjustment. That is.

An explanation will be given below based on an embodiment of the present invention shown in the drawings. 1 is a seat, 2 is a receiving hole, and 3 is a hole for a mounting screw. 9 is a box receipt. Reference numeral 4 denotes a rectangular cylindrical intermediate member, which is formed so that left and right side walls 5 and 6 have different thicknesses. The intermediate member 4 is integrally molded from, for example, resin.

The installation method is as shown in Fig. 2.
Install it by fitting it inside. At this time, the side walls 5 and 6 of the intermediate member 4 protrude into the receiving hole 2 of the receiving seat 1, and the stepped portion 5
₁ , 6 ₁ is in contact with the seat 1 and the intermediate member 4 is in the receiving hole 2
This prevents them from leaving.

FIG. 3 is a front view of the installed state. When the door D is closed in this state, the latch 12 of the door lock 11 protrudes and engages, and the back surface 12a of the latch 12 abuts against the side wall 6 of the intermediate member 4. 4). Next, in the state shown in FIG.
0 is loosened, the catch seat 1 is removed, the intermediate member 4 is fitted with the left and right reversed, and the catch seat 1 is attached. At this time,
Since the back surface 12a of the latch 12 comes into contact with the thick side wall 5, it absorbs the rattling of the door D and provides a suitable closed state (as shown in the fifth figure).

Incidentally, if a suitable closed door state can be obtained without using the intermediate member 4, it goes without saying that the intermediate member 4 may be removed (as shown in the sixth figure).

In addition, the intermediate member 4 is constructed by forming side walls 5a, 5b and 6a, 6b of different thickness above and below the left and right side walls 5, 6 of different thickness, respectively, as shown in FIGS. 7 to 9. The contact part can be adjusted in four stages.

Further, as shown in FIG. 10, the intermediate member 40 is formed into an isosceles rectangular tube shape, and the four side walls A, B, C, and D of the opening at one end are formed to have different thicknesses, so that one end The abutting portion with the latch 12 can be adjusted in four stages using only the latches. Furthermore, by forming side walls having different thicknesses at the other ends, the contact portion with the latch 12 can be adjusted in eight steps using one intermediate member. In the figure, 40a is a flange portion for preventing the intermediate member 40 from coming off from the receiving hole of the receiving seat.

Incidentally, it is appropriate that the difference in the thickness of each side wall is about 0.5 to 1.0 mm.

As described above, according to the present invention, an intermediate member having at least two or more side walls with different thicknesses is removably fitted between the catch seat and the box holder, and when fitting, the side wall portion of the intermediate member is attached to the catch seat. At the side edge of the opening of the receiving hole,
The back side of the latch of the door lock is brought into contact with the side wall, and the side wall that comes into contact with the latch can have a different thickness as desired, so that the contact between the catch and the back of the latch is improved. The gap between the abutting parts can be adjusted arbitrarily, and if the gap is too large, the door may rattle, or if the gap is too small, the latch becomes very heavy when operating, or the latch protrudes into the receiving hole. This can solve problems such as mismatching.

Further, according to the present invention, the above-mentioned adjustment can be made very simply by changing the position of the intermediate member and assembling it, and since the latch is brought into contact with the side wall of the intermediate member,
Even when a strong external force is applied, the thickness of the side wall does not change,
This has a significant practical effect, as there is no risk of misalignment of the contact portion with the latch during use.
