Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention is a push-pull type in which a latch bolt is reversed and moves forward and backward, and a lever handle or a grip ball type latch lock in which the latch bolt simply moves forward and backward, and prevents noise generated when the strike comes in contact with a mounting frame side. The present invention relates to a silence type latch lock.
[0002]
[Prior art]
Conventionally, there has been proposed a latch lock having a latch bolt provided with a cushioning material at the center in the vertical direction as invented in Japanese Utility Model Application No. 59-8409 (Japanese Utility Model Application Laid-Open No. 60-120178).
[0003]
[Problems to be solved by the invention]
In the above conventional example, when the latch bolt is tilted, there is a problem that the upper or lower portion of the latch bolt without cushioning material comes into contact with the strike on the mounting frame side and generates noise, and this problem is solved. Is an object of the present invention.
[0004]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the present invention provides a latch lock in which a latch bolt provided with an inclined surface advances and retreats from a latch case. It consists of
[0005]
BEST MODE FOR CARRYING OUT THE INVENTION
The latch lock of the present embodiment is a push-pull type latch lock, and the latch bolt 2 reverses and moves back and forth from the front surface of the latch case 1.
[0006]
The latch bolt 2 is provided with recesses 3 on the upper and lower surfaces and bosses 4 at substantially the center thereof, and a storage portion 8 that opens rearward is provided at the rear center in the vertical direction. . By storing the tip of the slide plate 9 and the spring 10 in the storage portion 8 and driving the pin 11, the latch bolt 2 is attached to the slide plate 9 in a reversible manner, and advances and retreats together with the slide plate 9, and the spring 10 , And is maintained in a normal state in which it is not inverted.
[0007]
Then, a cushioning material 6 made of synthetic resin or rubber having a hole 7 corresponding to the boss 4 is fitted into the recess 3, and the cushioning material 6.6 is caulked on the upper and lower surfaces of the latch bolt 2 with the boss 4 and the hole 7. Stop it. The cushioning members 6.6 are attached so as to slightly protrude from the inclined surface 5 of the latch bolt 2, and when the door is closed, the cushioning members 6.6 come into contact with the strike 12 on the mounting frame side to suppress the generation of noise. it can.
[0008]
As shown in FIG. 4, when a push handle (not shown) is pushed or a pull handle (not shown) is pulled, the latch bolt 2 is disengaged from the stopper that has prevented the inversion, and the latch bolt 2 is inverted. Retracts into case 1 and door opens.
[0009]
FIG. 5 and FIG. 6 show another embodiment of the present invention, in which a cushioning member 16 made of synthetic resin or rubber provided on a latch bolt 13 is used in addition to the inclined surface 14. The vertical surface 15 opposite to the inclined surface 14 also protrudes as a protruding portion 17. Other configurations are the same as those of the above embodiment. In this manner, when the inverted latch bolt 13 returns with the restoring force of the spring, noise can be suppressed even when it comes into contact with the bush 18 made of synthetic resin. Therefore, it is possible to provide a latch lock effective for a push-pull latch lock having a reversing latch bolt.
[0010]
Although the above embodiment is a push-pull type latch lock, the present invention may be a lever handle type or a grip ball type latch lock, in which the latch bolt simply moves forward and backward without reversing.
[0011]
【The invention's effect】
As described above, according to the present invention, the cushioning material protruding forward is provided on the upper and lower portions of the inclined surface of the latch bolt, so that even if the latch bolt is inclined, any one of the cushioning materials on the upper and lower portions is provided. As a result, it is possible to prevent noise from being generated.
[0012]
In addition, when the latch plate has a slide plate or a spring at the center in the vertical direction and the cushioning material cannot be attached to the center or the strength is weakened even if it is attached, the cushioning material can be attached without inconvenience. There is also an effect.
