Description

DOOR LOCKING HANDLE DEVICE FOR DRAWING ROTATING OPERATING TYPE DOOR}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lock handle device for a pull-out rotation type door used for locking and opening and closing of doors such as storage boxes of various devices.

A lock that protrudes the bearing barrel on the back side of the end of the fixed case secured to the door, and inserts the main shaft into the bearing barrel so as to be rotatable and unmovable in the front-rear direction. Connect the fixed plate, protrude and install the joining boss on the front end of the spindle, and pivot the proximal end of the operation handle to the joining boss by the transverse pivot axis parallel to the door. The lock handle device for the door of the draw-out rotation operation type which was accommodated as possible is already known (for example, refer Japanese Unexamined-Japanese-Patent No. 1-patent 2504714).

In this conventional apparatus, the operation handle is immersed in the fixed case, the operation handle is pulled out of the fixed case, and the operation handle is rotated to the unlocked position. The spring bearing plate is fitted to the joint boss part without rotation, and the compression coil spring for pressing the spring bearing plate forward is pressed in the cavity provided on the back side of the spring bearing plate. The + -shaped click convex formed on the front side and the T-shaped recess formed on the back side of the base end of the operation handle are hooked and peeled off depending on the position occupied by the operation handle.

However, in such a retaining mechanism, the compression coil spring and spring bearing plate are indispensable components and neither of them is allowed. In addition, the inner cylinder dimension of the bearing cylinder length becomes much longer because a cavity for accommodating a relatively thick plate bearing plate and a compression coil spring having a certain length must be secured in the bearing cylinder portion. It is an obstacle.

To lock the operation handle to the fixing case.

The lock unit is stored, and the latch body interlocked with the locking axis of the lock unit is hung and removed from the receiving groove formed on the inner surface of the fixed case, so that the operation handle is not drawn out and rotated by an unauthorized person.

There has been a malfunction. In addition, when the rainwater stays in the lock unit, it is exposed to the risk of oxidative corrosion. Rainwater and sand dust particles are also intruded from the play between the main shaft and the bearing barrel. When used in a facility near the coast, cases have been reported in which the latch body of the lock unit is rusted and unable to move, or the bush between the spindle and the bearing barrel corrodes and the spindle does not rotate.

Therefore, the object of the present invention, the number of parts of the mechanism for holding the operation handle to a predetermined position can be omitted to the limit, the lock handle device for the pull-out rotation operation type door that allows compact design by the shortening of the bearing barrel To provide.

Another object of the present invention is to provide a lock handle device for a pull-out rotationally operated door that is precisely protected against intrusion of rain or sand dust particles and is highly durable even when used in a facility near a coast.
