The latch body protrudes into the slot, while the receiving body fixed to the door is provided with an engaging protrusion that enters the slot, and when the door is closed, the latch body is inserted into the recesses on both sides of the engaging protrusion. The hemispherical tips are engaged.

る。(Problem to be solved by the invention) However, this conventional door closing holder does not offer ease of operation in that the engagement between the receiving body and the latch body is automatically established at the end of the door closing. However, when the door is opened, the hemispherical tip is pushed into the side recess of the engagement protrusion and the latch body slides backward into the receiving hole, causing the receiving body and the latch body to separate. The engagement will be automatically released.

扉用閉鎖保持具を提供することである。 Therefore, the purpose of the present invention is to automatically engage the receiving body and the latch body when the door is closed, but to prevent the receiving body from engaging the latch body when the door is opened unless a special operation is performed before opening the door. It is an object of the present invention to provide a closing holder for a door that does not disengage from the body.

のである。(Means for Solving the Problems) The door closing holder of the present invention will be explained below using reference numerals in the attached drawings. A receiving hole 3 is provided in the main body 1 and is inclined so that the outer end thereof which is open to the inner end is located in front of the inner end. The distal end surface 4a of the body 4 is made to protrude obliquely to the inner surface 2a of the slot 2, and the receiving body 6 is restrained between the inner end of the slot 2 and the rear surface 4b of the latch body 4. It was designed to do so.

As the closing rotation of the door 7 further progresses, the receiving body 6 enters deeper into the slot 2 and presses the tip end surface 4a of the latch body 4, so that the latch body 4 resists the biasing force of the spring 5. It slides backward into the receiving hole 3.

It is constructed by being divided into two plate-like bodies 1a and 1b, which are connected by caulking the tip of a connecting projection 1c of the plate-like body 1a passing through a through hole 1d of the plate-like body 1b. The latch body 4 is constructed in the shape of a square bar, and has a retaining projection 4d protruding from the front side of the inner end.
The spring 5 is composed of a compression coil spring.

is composed of a round bar, and the mounting plate part 6a at the base end is attached with screws 9.
and nuts 10 to a bracket 11, and the bracket 11 is welded and fixed to the inner surface of the fixed frame 8. The main body 1 is fixed to the edge of the door with bolts 12.

動板１５の先端部に連結されている。 In the embodiment shown in FIGS. 8 and 9, the main body 1 is fixed to a fixed frame 8, and a receiving body 6 is provided on the door 7 side. This round bar-shaped receiving body 6 is inserted through a guide plate 17 fixed to the back side of the door 7, and the lower end of the interlocking link 16 is connected to the upper end by a pivot 18. The upper end of the interlocking link 16 has a pivot 19
is connected to the tip of a rotating plate 15 fixed to the rotor 14 of the locking device 13.

If the latch body 4 is slid backward into the receiving hole 3 by pushing the tip end surface 4a of the latch body 4, the engagement between the receiving body 6 and the latch body 4 can be released from the outside.

させ得る分力は生じない。(Effect of the invention) As described above, in the door closing holder of the present invention, the receiving body 6 is restrained between the innermost end of the slot 2 and the rear side surface 4b of the latch body 4 when the door is closed. However, since the receiving hole 3 in which the latch body 4 is housed is inclined so that the outer end that opens into the inner surface 2a of the slot 2 is located forward of the inner end, it is not open. Even if the rear surface 4a of the latch body 4 is pressed by the receiving body 6 by pulling the door 7 for operation,
The front side surface 4c of the latch body 4 is only pressed against the inner wall surface of the receiving hole 3, and no force that can cause the latch body 4 to slide backward is generated.

そのため、棒材やドライバー先端部等でラツチ
体４の先端部４ａを押さない限り、ラツチ体４は
受金体６が溝孔２から脱出可能な位置まで後退摺
動しない。 Therefore, unless the tip 4a of the latch body 4 is pushed with a bar, the tip of a screwdriver, etc., the latch body 4 will not slide backward to a position where the receiving body 6 can escape from the slot 2.

のを的確に防止することができる。 In this way, the door closing holder of the present invention prevents the engagement between the receiving body 6 and the latch body 4 unless a special operation is added to actively push the latch body 4 from the outside before opening the door. Although the structure is simple, it is possible to accurately prevent the door 7 from being opened unnecessarily.
