Description

[Detailed description of the invention] The present invention relates to a locking device for a door in a storage warehouse, etc., in which the door is locked to the upper and lower edges of the doorway of the cabinet body. This is what I did.

Next, to explain the details of the illustrated embodiment, 1 is the cabinet body, 2 and 2' are double doors, and the back side of the front plate 3 of the door 2 on the right side has a pull cover 4.
has one side edge fitted into the bent portion 3' of the open end of the top plate, and an engagement protrusion 4 protruding from the other side edge into the engagement hole 5'' drilled in the bent plate portion 5' of the back plate 5. The handle cover 4 has a square hole 6a in the longitudinal direction as shown in FIG. A tube 6 is rotatably installed vertically on the upper and lower walls of the handle cover 4 by being supported by 4a and 4b, respectively, and an operating rod 7 having a square cross section is passed through and held in the square hole 6a, and the upper and lower ends of the operating rod 7 are supported. latches 8, 8 are fixedly installed in the part, and this latch 8
is wound around the holding tube 6, one end is locked to an engaging protrusion 4'' protruding inside the handle cover 4, and the other end is wrapped around the holding tube 6.
The return spring 9 is engaged with the engaging piece 6c' of the door, and is engaged with the edges of the engaging holes 10, 10 formed in the upper and lower frame plates 1a of the doorway of the cabinet body 1. (Figure 4). In the figure, reference numeral 11 denotes a latch receiver attached to the bending groove at the top and bottom of the door 2. Reference numeral 12 indicates a pull opening 1 attached to the door top plate 3 within the pull cover 4.
2a, the pocket member 12 has a handle plate 13 having an approximately L-shaped cross section, and a handle portion 13a facing the handle opening 12a is approximately the same as the door top plate 3.
They are pivoted 13', 13' so that they are parallel to each other.
Further, on the inner surface of the handle cover 4, a connecting plate 14 having bent locking pieces 14a and 14b at both ends thereof is slidably provided via guide pieces 4c and 4c, and one of the locking pieces 14a is connected to the holding tube. 6, and the other locking piece 14b engages with the upwardly projecting edge 13b' of the operating arm 13b of the pull plate 13. Although the connecting plate 14 is not shown, it can be easily attached between the guide pieces 4c by providing a notch groove parallel to the guide piece 4c in the handle cover 4 near the guide piece 4c to make it elastically deformable. can.

In the figure, 15 is a lock provided at the lower part of the pocket member 12. When the lock is locked, the operating piece 15a rotates and engages with the lower engagement piece 6c of the holding tube 6 to prevent rotation of the holding tube 6. It is designed to be locked. When the door is closed, the inner edge 16 of the left door 2' enters the inside of the right door 2, so just by locking the right door 2, the left door 2' is also locked. .

Since the door locking device of the present invention has the above-mentioned structure, simply by hooking the hand to the handle portion 13a of the handle plate 13 and pulling it, the operating arm 13b and the connecting plate 14 engaged therewith
As the holding tube 6 rotates in the direction of arrow A against the return spring 9, the latch 8 also rotates and is disengaged from the edge of the engagement hole 10 of the cabinet body 1. Therefore, the door 2 can be opened by pulling the handle portion 13a, and the left door 2' is also unlocked.

To close, simply rotate the door 2 inward, and the inclined back surface 8' of the latch 8 will engage with the edge of the engagement hole 10, and the latch 8 will return and rotate against the spring 9 to engage. After passing through the hole 10, it is returned by the return spring 9 and is locked to the edge of the engagement hole 10 again.

The door locking device of this invention is installed on the handle cover 4.
As described above, return the holding tube 6 wrapped with the spring 9 to the handle cover 4 and attach the connecting plate 14, and connect the bent locking piece 14a on one side of the connecting plate 14 to the upper part of the holding tube 6. If it is engaged with the piece 6b, when assembling, insert the operating rod 7 into the holding tube 6, attach the latch 8 to its tip, and attach the handle cover 4 to the back side of the front plate 3 of the door 2. An engagement hole is formed in the folded plate part 5' of the door back plate 5 with an engagement protrusion 4' which fits into the bent part 3' of the open end of the plate 3 and which protrudes from the other side edge. 5" and install it, then pull plate 1
3 is attached to the door front plate 3 inside the handle cover 4, and the operating arm 1 of the handle plate 13 is attached.
3b to the other bent locking piece 14b of the connecting plate 14.
The locking device can be attached to the door with an extremely simple operation of engaging with the locking device, and the handle cover 4 can also be attached extremely easily as described above, which has the advantage of significantly simplifying the assembly process. ing.
