Description

[Detailed Description of the Invention] The present invention relates to an improvement of a device for attaching a locking piece to a locking rod of a locking device or the like.

Conventionally, when attaching a locking piece to a locking rod of a locking device,
It was usually welded or screwed.

For this reason, there was a drawback that it took time and effort to attach the locking piece.

The present invention aims to provide a device for attaching a locking piece of a locking device, etc., which has a simple structure and can be easily installed. A locking rod having four notches on both sides of the locking rod is provided with a hook-shaped locking portion at the tip and a retaining groove continuous to the locking portion and a retaining groove on the inner surface that engages with the notch recess. This is a locking piece attachment device for a locking device, etc., characterized in that a locking piece consisting of a two-pronged attachment piece having a certain degree of elasticity is attached.

The present invention will be explained below with reference to the drawings.

1 includes left and right side plates 21, 21', a bottom plate 22, a top plate 23,
It is a storage cabinet consisting of left and right doors 3', 3, etc.

A locking device 4 is built into the back of the door 3, and locking pieces 6 attached to the top and bottom ends of a locking rod 41 protrude from the back of the upper and lower ends of the door 3, and engage with the top plate 23 and the bottom plate 22. There is.

The locking rod 41 is rotatably mounted by operating a locking rod operation piece 51 projected into a pull portion 5 attached to the door 3, and is given elasticity to always rotate in the locking direction.

The locking rod 41 and the locking piece 6 of the locking device 4 configured as described above are configured as follows and are connected to each other.

The locking rod 41 is made into a flat shape by crushing the tip of a round steel, and the central part on both sides is cut inward to form a notched recess 42.
, 42' are formed, and constitute the locking piece attachment part 43.

The locking piece 6 is molded from synthetic resin, and has a locking part 61 with a hook-shaped tip, and four notches 42 and 42' on the inner surface continuous to the rear part of the locking part 61. Engaging retaining groove 6
It consists of two fork-shaped mounting pieces 63 and 63' having a certain degree of elasticity and having a width of 2.62'.

After positioning the inner space 64 of the mounting piece 63, 63' of the locking piece 6 on the round steel part of the locking rod 4 configured as described above, the locking piece 6 is pushed down and locked. The upper end surface of the locking piece attachment part 43 provided at the lower end of the rod is the attachment piece 63.
The engagement groove 62° provided on the inner surface of 63' comes into contact with the inner surface of 62'.

When the locking piece 6 is further pushed down from this state, the mounting pieces 63 and 63' are lowered in an outwardly open state, and when they are finally located in the cutout recesses 42 and 42' of the locking piece mounting part 43, the mounting pieces 63.63' moves inward due to elasticity.

In this state, the engagement groove 62.6 is inserted into the notch recess 42, 42'.
2' are engaged, and the upper and lower end surfaces of the cutout recesses 42 and 42' sandwich the -L lower end surfaces of the mounting pieces 63 and 63'.

Therefore, the locking piece 6 can be attached to the locking rod 4 without moving in either the right, left, or right direction below the L.

As mentioned above, the present invention simply crushes the end of the locking rod 4,
The structure is very simple, with only cutout recesses 42 and 42' provided on both sides, and since the locking pieces are molded from synthetic resin, it is necessary to add special elasticity members to the mounting pieces 63 and 63'. There is no such thing, and it can be easily manufactured using a mold.

The present invention is not limited to a device that attaches a locking piece to a locking rod of a locking device, but can be used as long as it is a device that crushes a round steel at an appropriate position and attaches a synthetic resin member to that part. It is.

As described above, the present invention is a locking piece attachment device for a locking device, etc., which has a simple structure, is extremely easy to attach, and has a secure attachment condition, and is a practical and useful device.
