Description

[Detailed description of the invention] This invention relates to a three-way locking position for doors of lockers, etc., by simplifying the operating mechanism of the upper and lower rods that temporarily fasten the door as much as possible to ensure reliable operation. This has been improved to make it easier to assemble the parts.

,'-゛□The doors of lockers, etc. are equipped with a three-way locking device consisting of a normal locking means such as a cylinder lock and a temporary locking means that temporarily locks both the upper and lower rods to the main body when the door is closed. It is a provision.

However, the conventional three-way tightening device has a structure in which the operating mechanism and locking device for raising and lowering both the upper and lower rods are separately provided, so there are two suvs required for installation, which is cumbersome to process. In addition, the number of parts increases and the installation process becomes complicated, which is extremely disadvantageous in terms of cost.

An example of an improved version of this conventional device is the Utility Model Act of 1973. 221.31: A three-way locking device as disclosed in Publication No. The mechanism for operating the upper and lower rods in this improved device is superior in that it is constructed in one unit.The mechanism for operating both the upper and lower rods in this improved device is: Since the structure is such that separate operating levers are connected to the upper and lower rods, force is often generated in the operating mechanism, positioning of parts is troublesome, and assembly work is difficult. There are some problems that are not easy.

In addition, the present invention requires fewer parts than these conventional known devices, and the door handle is easily incorporated into the door handle, improving stability. Although the present invention is intended to provide a locking device, the three-way locking position for doors of lockers, etc., which is a feature of the present invention, will be explained with reference to the embodiment shown in the attached drawings. The member 1 has a recessed part 2 for the handle and a housing part 3 for the mechanism, and the housing part 3 has a pair of upper and lower sliding bodies 14 for operating the lock 11 and the upper and lower locks 12 and 13 for temporarily fixing the door. .15
In a three-way locking device for a door such as a locker, the upper sliding body 14 and the lower sliding body 15 are connected to the bottom plate 4 of the storage section 3.
Both ends 16 of a connecting rod 16 with a central portion pivoted 16a' on top
a, 16b, respectively, and the upper side of the lower sliding body 15 is formed into an operating lever 15a bent toward the inside of the recessed part 2, so that this operating lever 15a projects into the recessed part 2, and the above-mentioned A spring 17 is provided between the sliding bodies 14 and 15 to bias the sliding bodies 14 and 15 in the direction of separating them.
On the other hand, a stopper 19 is provided on the hook 18 of the lock 11 fixed to the housing portion 3, and this stopper 19
The lower sliding body 15 is provided with a locking protrusion 20 located directly below the passage through which the lower sliding body 15 moves.

In the above configuration, it is disclosed in the above-mentioned Japanese Utility Model Publication No. 55-22131 that the handle is configured so that the member 1 can be detachably fixed to a fitting hole formed in the door (not shown). The handle member 1 has a partition wall 5 with a recess 2 for the handle and a housing 3 for the mechanism.
It has two rooms.

The upper sliding body 14 has a handle that slides into a cutout 6a provided in the upper side wall 6 of the member 1, and the lower slider 15 has a handle that slides into a notch 7a provided in the lower side wall 7 of the member 1. Pins 21.22, which are loosely inserted and fixed to both the upper and lower sliding bodies 14.15, engage with both ends 16a and L6b of the connecting rod 16, and the tips of these pins 21.22 are attached to the top of the bottom plate 4. They are loosely inserted into guide grooves 8 and 9 provided in the guide grooves 8 and 9, respectively.

Both ends 16a and 16b of the connecting rod 16 are formed into two forks.

In addition, an operating lever 15a that is integrated with the lower sliding body 15
is formed by first bending the upper part of the lower sliding body 15 in the horizontal direction, then bending it upward, and then bending it further in the horizontal direction and finally protruding into the recessed part 2, A spring 17 biasing the upper and lower slides 14, 15 away from each other is connected to the operating lever 1 in the illustrated embodiment.
The base portion 15b of the member 5a and the handle are hooked between the lower side wall 7 of the member 1.

In addition, 5a in the figure is a notch provided in the partition wall 5, and the operating lever 15a projects into the recessed part 2 through this notch 5a.

9 is a cover plate for covering the storage portion 3; 9a is a tongue piece for mounting the cover plate; 9b is an escape hole for the lock 11;

According to the above configuration, when the operating lever 15a is pushed up against the spring 17 in the state shown in FIG.
The lower sliding body 15 integrated with a is pulled up, and the upper sliding body 14 is pulled down via the connecting rod 16, and both the upper and lower rods 12 and 13 are pulled together as shown in FIG. 2, and the door can be opened. It becomes a posture.

On the other hand, in the state shown in FIG.
3 is protruded and temporarily fastened to the main body (not shown).If the lock 11 is locked with the duplicate key 23 during this temporary fastening, the latch 18 protrudes as shown in FIG. A stopper 19 that moves together with the hook 18 is located directly above the locking protrusion 20 provided on the moving body 15,
This prevents the operating lever 15a from being pushed up.

Therefore, it is possible to close the door on three sides using the lock 11 and both the upper and lower rods 12 and 13.

The present invention is as described above, and has a structure in which both the upper and lower sliding bodies are connected by a connecting piece, and the operating lever is provided integrally with the lower sliding body, so the operating mechanism of both the upper and lower rods is an extremely simple structure. Of course, this has the advantage that the lower sliding body can be operated directly by the operating lever, eliminating rattling and allowing smooth operation.

In addition, the number of parts can be extremely reduced, making assembly work easier and faster.In addition, the stopper part of the operating lever is provided on the lever itself, which is different from conventional devices. This also solves the space problem.
It has the advantage that the entire mechanism can be compactly and stably built into the handle, and combined with the fact that costs can be drastically reduced, its practical value is extremely great.
