JPS6013978Y2 - Connection part of latch member for opening/closing door - Google Patents

Description

[Detailed description of the invention] The present invention uses a locking device for three-way closing of a door, etc., in which the upper and lower latch members provided on the door side are formed into a particularly rigid tube body, and the tube body and the locking device side are connected to each other. It relates to the connection part with the assembled actuator.

For example, the locking device body generally designated by the reference numeral 1 in FIG. 1 has a latch 3 slidably provided in the case body 2 coupled to a cylinder lock 4, as can be understood from the figure.
This hook is slid by rotating the inner cylinder of the cylinder lock 4, which is activated by operating the key 3, and the hook locks the tip 3a of the hook 3 into a vertical stile on the main body side of a steel locker, etc. In addition, the hook connects the actuator 5 to the metal 3 so that it can slide in the vertical direction, and the rod connected to the actuator 5 (
(not shown) can be hooked onto the upper and lower stiles of the main body, respectively.

However, since the rod connected to the actuator 5 is generally a round bar, it is heavy, and this weight becomes a burden when the lock slides, making it difficult to operate the key smoothly. In addition, the structure of the connection part that connects the actuator 5 and the rod is complicated, and the connection work is very time-consuming.

In order to solve these problems, the present invention uses a rigid tube instead of a round bar as the hook and stop member, thereby reducing the weight of the entire locking device.
The opening/closing door locking hook provides a connecting part for the stopper member, which can make the connection work with the pipe body easier, and embodiments of the present invention will be described below with reference to the drawings.

A hollow cylindrical body 11 is formed at the tip of the actuator 5 that is slidably assembled to the locking device body 1 described above, and a slit is formed in a part of the circumferential surface of the hollow cylindrical body 11 in the circumferential direction. 12 are drilled.

The inner circumferential edge of the mouth of the hollow cylinder 11 is chamfered, and a locking protrusion 13 as shown in FIG. 3A or FIG. 5 is vertically provided on the inner bottom and side walls.

Reference numeral 14 denotes a rigid hooking tube made of a hard plastic pipe or a metal pipe;
A substantially warhead-shaped connector 15 made of hard plastic or metal is connected and fixed to the root end 14a of 4 by caulking 16.

The connector 15 is formed in a thickness that can be inserted into the hollow cylinder 11, and has a rounded tip 1 like a warhead.
A key groove 15b is recessed in the axial direction on one side surface of the connector 5a, and a locking groove 17 is recessed in the circumferential direction in a part of the side surface of the intermediate portion of the connector 15.

When the connector 15 is inserted into the hollow cylinder 11, the key protrusion 13 provided inside the hollow cylinder 11 fits into the key groove 15b as shown in FIG. Prevent rotation.

Furthermore, the recessed position of the locking groove 17 allows the connector 15 to be
The locking groove 17 is designed in advance so as to fit exactly inside the slit 12 when inserted into the slit 12, as shown in FIG.

Next, a retaining spring member generally indicated by the reference numeral 18 in FIGS. One of the leg rods has a connector 15 that engages a part of its side into the slit 12 and connects to the locking tube 14.
The other leg rod is connected to an elastic curved rod 18b that comes into elastic contact with the surface of the cylindrical body just opposite to the surface on which the slit 12 is provided. ing.

Since the present invention has the above-described configuration, when connecting the locking tube 14 to the actuator 5, first attach the locking spring member 18 to the circumferential surface of the hollow cylinder 11 provided on the actuator 5. 4. Attach as shown in Figure 4, and then attach the hook to the root end 1 of the stopper tube 14.
The connector 15, which has been caulked and connected to 4a in advance, is deeply inserted into the hollow cylindrical body 11.

When the connector 15 is inserted, the elastic locking rod 18a of the stop spring member 18 that has been engaged in the slit 12 of the hollow cylindrical body 11 engages with the locking groove 17 of the connector 15, so that the hollow The cylindrical body 11 and the connector 15, that is, the actuator 5 and the locking tube 14 are connected.

During this connection, a portion of the elastic locking rod 18a of the stop spring member 18 elastically clamped to the hollow cylinder 11 projects onto the insertion passage inside the hollow cylinder 11 through the slit 12 shown in FIG. This attempts to prevent the connector 15 from being inserted, but since the tip 15a of the connector 15 has a rounded shape and the elastic locking rod 18a is made of a spring material,
Since the elastic locking rod 18a is pushed by the tip portion 15a and retreats outward, the connector 15 can be inserted without any problem.

Incidentally, in the embodiment described above, a connection method is shown in which the locking spring member 18 is elastically clamped by the hollow cylindrical body 11 in advance, and then the connector 15 is inserted.
may be adhered to the hollow cylindrical body 11 after the connector 15 is inserted.

Further, the locking groove 17 may be configured to be recessed around the entire circumference of the connector 15.

When the locking groove 17 is provided all around the circumference in this way, the key protrusion 13 and the key groove 1 provided for positioning and rotation prevention.
5b is no longer necessary, which has the advantage of simplifying the connection operation and simplifying the structure of the connection part.

As mentioned above, in the present invention, the locking member of the opening/closing door is formed by a tube body instead of the conventional round bar, so it is possible to reduce the weight of the entire locking device. It has the advantage of being extremely light and smooth to actuate, and also has the advantage that connection operations can be done quickly with a single touch thanks to the action of the stop spring member.Furthermore, it has the advantage of being able to perform connection operations quickly and easily with a single touch due to the action of the stop spring member.Furthermore, it also has the advantage of being able to perform the connection operation quickly with a single touch due to the action of the stop spring member.Furthermore, it can also be used to connect the difficult-to-connect stop member, that is, the connection between the pipe body and the actuator. Since the connector attached to the tube body is inserted into a hollow cylinder provided on the actuator and secured with a retaining spring member, it has the advantage of being robust and having a high probability of failure, which is of high practical value. .
