Description

[Detailed Description of the Invention] The present invention relates to an improvement of a locking device for locking a door by locking a latch mechanism in an article storage or the like.

By rotating the rotating plate pivoted on the back of the door,
The door can be closed or opened by inserting the latch installed at the appropriate position on the back of the door into the retaining hole drilled in the opening edge of the casing or into the door side. There is a storage room for items.

Conventional door-side locking devices of this type include a movable piece such as a cylinder lock attached to the door that enters the rotation trajectory of the rotation plate to prevent the rotation of the rotation plate. However, with such a locking device, if you open the door without knowing that it is locked, the rotating plate and the movable piece will collide, causing an unpleasant sound or causing the lock to rotate. There are drawbacks such as the need to attach it to the door close to the board.

Moreover, in this type of door, an opening/closing operation handle for rotating the rotating plate and a linking means for linking the rotating plate with each latch are provided near the rotating plate.
It is structurally difficult to provide the lock close to the rotary plate, and there are other drawbacks such as the inability to provide the lock at the optimal position for locking.

The object of the present invention is to provide a door locking device for an article storage, etc., which eliminates the above-mentioned drawbacks and difficulties, and will be explained below based on an embodiment shown in the accompanying drawings.

Reference numeral 1 denotes a case in an article storage, with a vertical shaft 2 at the edge of the front opening, and left and right doors A.

B is pivoted.

Both doors A and B are provided with an opening/closing operation mechanism C, which will be described later.

Door B is provided with a locking device to be described later, but door A is not provided with such a locking device.

However, a protruding piece 3 is formed on the rear edge of the free end of the door A.
When the door B is closed after the door B is closed, the projecting piece 3 comes into contact with the rear edge of the free end of the door B, so that the door A cannot be opened unless the door B is opened.

At the center of the rear surface of each layer A, B, a rotating plate 4 constituting an opening/closing operation mechanism C is pivotally mounted with a shaft 5 extending in the front-rear direction.

Note that the opening/closing operation mechanism C provided on the door A is symmetrical with the opening/closing operation mechanism C on the door B, so only a portion thereof is shown.

One end of a flexible wire 6° 6' is fixed to eccentric portions of the rotating plate 4 above and below the shaft 5 and equidistant from the shaft 5.

The wire 6.6' is attached to a guide roller 7.7 which is pivoted at a suitable position in each layer A, B on the side of the point where the wire 6.6' attaches to the rotating plate 4.
After winding ', the other end is linked to latching devices 8, 8' provided at appropriate positions above and below the rear surfaces of each layer A, H.

A latching device 8 is provided for each layer A, B, as clearly shown in FIG.
A fast-forming mounting bracket 9 is fixed to the housing 1, and the mounting bracket 9 holds the housing so as to be slidable in the vertical direction, and enters an engagement hole 10 cut in the vicinity of the opening of the housing 1 at the upper end. A latch 11 equipped with a hook-shaped engagement claw 11a that can be moved in and out, and a latch shaft 12 that projects from the lower end of the latch 11 and extends through the lower piece 9a of the mounting bracket 9. Latch shaft 12 between the lower end of latch 11 and lower piece 9a
It consists of a compression coil spring 13 compressed around the periphery.

The other end of the wire 6 is fixed to the lower end of the latch shaft 11.

Normally, the latch 11 is urged upward by the compression coil spring 13, and its engagement claw 11a projects into the engagement hole 10, but as the rotation plate 4 rotates, the wire 6 is pulled down. When this occurs, the latch shaft 12 and the latch 11 move downward, and the engagement claw 11a of the latch 11 is disengaged from the engagement hole 10, allowing each layer A and B to be opened freely.

, □In addition, the engaging claw 11 of the latch 11
The tip of the latch 11a is shaped like a point, so that when the doors of each layer A and B are closed, the engagement claw 11a of the latch 11 can temporarily contact the opening edge of the casing 1 without operating the handle 16, which will be described later. After being pushed down, it can automatically plunge into the retaining hole 10.

The lower latch device 8' has a vertically symmetrical structure with the upper latch device 8.

That is, the latch device 8' includes the mounting bracket 9 of the latch device 8, the lower piece 9a, the latch 11. The engaging claw 11a,
The mounting bracket 9', which is vertically symmetrical with the latch shaft 12 and the compression coil spring 13, the upper piece 9a, the latch 11', the engaging claw 11a', the latch shaft 12', and the compression coil spring 1
3', and has the same function as the latch device 8.

A retaining hole corresponding to the engaging hole 10 is located in the bottom plate 1 of the housing 1.
The engagement claw 11a' engages and disengages there, but is not shown.

A window hole 14 is cut on the side of the pivoting part of the rotating plate 4 in each layer A, B, and the window hole 14 is provided with a handle frame 1 which is opened at the front.
5 is fitted.

As clearly shown in FIGS. 4 and 5, on the top of the handle frame 15, the upper end of a plate-shaped opening/closing operation handle (hereinafter simply referred to as a handle) 16 has a handle shaft 17 facing in the left-right direction. It is pivotally connected to the shaft 17 so that it can rotate together with it.

A bent piece 17a facing rearward was bent at the end of each handle shaft 17 near the rotating plate 4.

The free end of the bent piece 17a contacts the upper edge of the arm 4a of the rotating plate 4, which extends inward from the shaft 5, and by pulling the lower end of the handle 16 toward you, the handle 1
When the handle shaft 17 rotates together with 6, the bending piece 17
a pushes down the arm 4a, slightly rotates the rotating plate 4 around the axis 5, and connects the upper and lower latches 11 via the wire 6.6'.
．． 11' can be drawn inward.

A suitable projection 4b is formed at the upper part of the free end of the arm 4aρ in order to prevent the bent piece 17a from separating from the upper edge of the arm 4a.

Thus, the opening/closing operation mechanism C is formed by the rotating plate 4, the wire 6.6', the latch device 8.8', the handle 16, the handle shaft 17, etc.

A cylinder lock 18 is provided at the bottom of the handle frame 15 of the door B so that a key (not shown) can be inserted from the front.
is installed.

The cylinder lock 18 includes a cylindrical outer cylinder 19 that is rotatably attached to the rear surface of the door B, and a rotary 20 that can be rotated approximately 180 degrees by inserting and turning a key within the outer cylinder 19.
At the rear of the rotary 20, a movable piece 21 is provided that penetrates the outer cylinder 19 in the left-right direction.

A U-shaped notch 22 is cut in the lower central edge of the movable piece 21, and a pin 23 protruding from the rear end eccentric portion of the rotary 20 is engaged with this notch 22.

Thus, by inserting the key into the cylinder lock 18 and turning the key appropriately, the rotary 20 and the pin 23 are rotated, and the movable piece 21 is moved to the right in FIG. 7 as shown by the solid line. (when locked), or moved to the left in FIG. 7 (when unlocked) as shown by the imaginary line in FIG.

Reference numeral 24 denotes a flexible wire, one end of which is fixed to the same part of the rotating plate 4 as the fixed point of the wire 6'.

After the wire 24 is wound around the guide roller 7' together with the wire 6', the wire 24 is separated from the wire 6' and hangs down. After being wound, it extends horizontally toward the free end of the door B, and the other end is fixed to one end of the movable piece 21 of the cylinder lock 18.

The wire 24 is tensed when the movable piece 21 is in the locked position shown by the solid line in FIG. When the guide roller 25 is located at
This allows the rotating plate 4 to rotate.

Thus, a locking device is formed by the cylinder lock 18, the wire 24, etc.

The operation and handling of the device described above will now be described.

When the movable piece 21 of the cylinder lock 18 is in the unlocked position, the wire 24 is slack as described above.
Pull the handle 16 toward you and bend the handle shaft 17 into the bent piece 1.
7a in the clockwise direction in FIG. 2, the latch 11.7a is rotated via the wire 6.6'. , jl' inward, latch 11.11
'The engaging claws 11a, 11. a' can be removed from the engagement hole 10 or the like.

□゛Therefore, in this state, both doors A and B can be freely opened and closed by operating the handle 16.

In addition, when each layer A and B are completely closed, each layer A.

Each latch 11.11' (7) engaging claw 11 a in B
, 11 a' once contact the opening edge of the housing 1 and move inward, and then automatically enter the engagement hole 10 or the like.

After closing door A, close door B, and then lock cylinder lock 1.
When the movable piece 21 is moved to the locked position by inserting the key into the key 8 and turning it, the wire 24 becomes tense and restricts the rotation of the rotating plate 4, so that even if the handle 16 is operated, the rotating plate 4 does not move.
does not rotate, and the latch 11, 11' on the door B cannot be removed from the engagement hole 10.

Therefore, door B cannot be opened.

Further, door A is opened by latch 11. by operating handle 16.
11' can be removed from the engagement hole 10 etc., but
Due to the engagement between the protruding piece 3 and the door B, the door cannot be opened.

Therefore, by locking the door B side, both doors A and B cannot be unlocked.

Of course, in order to open the doors A and B again, it is sufficient to insert the key into the cylinder lock 18 and turn it, move the movable piece 21 to the unlocked position, and loosen the wire 24.

As is clear from the above, in the present invention, the rotary plate and the lock are connected by a cord such as a wire, so when the handle is operated when the lock is locked, an unpleasant collision sound is generated as in the conventional case. By making the cable longer, the lock can be installed in any position, which is extremely convenient.
