Description

[Detailed Description of the Invention] The present invention relates to a door latch mechanism, and its purpose is to expand the internal accommodation space within the housing of a locker, etc., and to
The latch mechanism is constructed so that it can be released by a one-touch operation in relation to the door handle.

For this reason, in the present invention, a latch cover plate is provided on the back side of the door body, a handle is provided in the gap formed between the door body, and the front edge of the top plate of the case and the front edge of the bottom plate are bent. The latch bolts facing the latch holes provided in the edges are arranged above and below the gap in the door body, and the handle and the latch bolts are connected by a flexible wire. Based on this, the gist of the present invention will be explained.

Figures 1 and 2 show a locker equipped with the latch mechanism of the present invention.
is attached to the bow. Reference numeral 4 denotes a handle, which has a window 5 into which a fingertip is inserted.As is clear from FIG. 8 and partition plates 9 and 10 that separate the upper and lower parts.
An opening 11 is formed on the opposite side of the side plate 8, and is surrounded on three sides by the opening 11, into which a fingertip is inserted. As shown in the second figure, the pull handle 4 is housed in a gap between the latch cover plate 12 fixed to the back side of the door body 2 and the door body 2.
It is parallel to a back plate 13 that covers approximately half of the cover, and is fixed by bolts 15 via a cover mounting frame 14 shown in the fourth figure. Therefore, the cover plate 12 can be easily removed by unscrewing the bolts 15. A latch lever 16 shown in FIG. 1
8, 19, and 20, and a slit 21 is provided in the center of the joint between the horizontal frames 18 and 19 and the vertical frame 17, through which the tip of a flexible wire 23, which will be described later, is inserted. is lock 42
A keyhole 22 is provided through which a lever (shown in the first diagram) is inserted. The horizontal frames 18 and 19 of this latch lever 16
are accommodated in spaces 9a and 10a above the partition plate 9 and below the partition plate 10 in the container casing 6 shown in FIG.
It is housed in the housing 6 so as to face the. Therefore, the latch lever 16 shown in FIG. 9 is housed in the case 6 shown in FIG.
As shown in the figure. However, the latch lever 16 is provided with a gap d that allows it to move laterally within the housing 6, and with a fingertip inserted through the window 5,
The latch lever 16 is operable in the direction of arrow A in FIG. Further, the lowermost horizontal frame 20 of the latch lever 16 protrudes downward from the housing 6 through a cutout 6a (see FIG. 8) provided at the bottom of the housing 6, as shown in the same figure. It is arranged to face 42 levers. Next, the tips of the two sets of flexible wires 23 shown in FIG. 11 are passed through the cord holes 24 of the housing 6 shown in FIG. , its head 23a is suspended, and the head 23b at the other end is connected to a latch bolt actuator to be described later. As shown in FIG. 5, the latch bolt actuator 25 has a box shape with one side open, and
The latch bolt 26 bent into the shape shown in the figure is
Upper and lower notches 2 of the illustrated latch bolt actuator 25
7, 27 and tightened through the screw hole 29 of the boss 28 fixed inside the actuator 25, while the head 23b of the other end of the flexible wire 23 is inserted through the slit 30 and engaged. The head 23b is covered with a cylindrical cover 31. As shown in FIGS. 3 and 7, this latch bolt actuator 25 is loosely fitted into a guide frame 32 provided inside one end of the bent upper edge 12a and lower edge 12b of the latch cover plate 12. The latch bolt 2 is moved inside the guide frame 32 along guide holes 33, 33.
6 is bent and protrudes from the guide hole 33 to form the bent front edges 34 of the top plate 34 and bottom plate 35 of the casing 1 shown in the second figure.
They are inserted through latch holes 36 provided in holes 35a and 35a, respectively, facing each other. Reference numeral 37 denotes a protrusion cut and raised in the guide frame 32, and a pressure expansion spring 38 is interposed between the latch bolt actuator 25 housed in the guide frame 32 and the actuator 25 is moved together with the latch bolt 26 in FIG. Contract in the direction of the upward arrow A' and tighten the latch bolt 26.
is suspended in the latch hole 36 as shown in the fourth figure. Reference numeral 39 denotes a protrusion provided within the actuator 25 so as to lock one end of the spring 38. Furthermore, the latch cover plate 1 shown in FIGS. 2 and 7
A pair of through holes 40 formed in the handle 2 are arranged to face a pair of screw holes 41 provided in the handle 4 shown in FIG. 8, respectively, for bolt tightening.

To describe the operation of the latch mechanism of the present invention having the above-mentioned configuration, when the door bodies 2 and 3 are closed, the latch bolt 26 is moved together with the latch bolt actuator 25 by the contraction elasticity of the spring 38 at the arrow mark A in FIG. 3. The door body 2 is simultaneously locked by the latch bolts 26 and 26 provided along the upper and lower edges of the door body 2, respectively, in order to lock the hook portion in the locking hole 36 as shown in the fourth figure. To release the latch lever 16, the lever 16 is moved in the direction of arrow A in FIG. will be moved to As a result, the latch bolt actuator 25
together with the latch bolt 26, the guide holes 33, 3 are moved in the direction opposite to arrow A' against the elasticity of the spring 38.
3, the locking action of the latch bolt 26 is released, and the door body is opened. Next, when closing the door bodies 2 and 3, first close the left door body 3, then close the right door body 2, and the latch bolt 26 will lock the door with its curved edge 26a. Due to the pressing force of the body in the closing direction, the spring 38 is expanded and automatically pushed into the locking hole 36 to be locked.

As described above, according to the present invention, the front edges of the top plate and bottom plate of the Rocker housing are bent, a latch hole is provided in the front edge, and the latch bolt is inserted and locked from the front side. The space can be expanded and fully utilized, and when opening the door body, the fingertip must be inserted into the handle and at the same time push the fingertip to the side to pull the door body open. The latch bolt can also be released at once, so it has the excellent feature of killing two birds with one stone by releasing the latch bolt with one touch, and has great practical benefits.
