Description

The present invention relates to a locking handle device attached to a door of a storage box such as an electric device.

In a conventional locking handle device, a handle case is embedded in a mounting hole formed in the front portion of the door to fix the handle case to the door, and the operation handle is connected to the handle case by a pivot parallel to the door front. The latch plate is arranged on the back of the handle case. By pulling the operation handle out of the handle case and rotating it, the latch plate is rotated in parallel with the front of the door, and the front opening of the box body It was made to engage / disengage with the metal receiver provided inside the edge frame portion (see Patent Document 1).

The locking handle device of Patent Document 1 is called a flat handle and has the advantage that the amount of protrusion to the front side of the door is extremely small, but the handle case is embedded in the front part of the door, and the latch plate is the box body. Therefore, there is an inconvenience that a space for installing an electric device or the like in the box body or the front surface of the door is reduced by that amount.

In order to eliminate the inconvenience, there has been proposed a locking handle device in which a locking member such as a latch plate is not positioned in the front opening of the box body (Patent Document 2).

The handle device for a lock of this patent document 2 has a receiver fixed to the outer surface of the edge frame portion of the front opening of the box body, a handle case fixed to the outer surface of the door, and a door outer surface. An operation handle having an intermediate portion connected to the intermediate portion of the handle case by a first vertical axis, and an operation link having a base end portion connected to the distal end portion of the operation handle by a second vertical axis perpendicular to the door outer surface. The base end portion is connected to the end portion of the handle case by a third pivot axis perpendicular to the door outer surface, and the intermediate portion is connected to the distal end portion of the operation link by a fourth pivot axis perpendicular to the door outer surface. The latch lever includes a latch lever, and a tip hook portion of the latch lever is engaged with the receiver by rotating the operation handle.

However, in this locking handle device, in the closed and locked state of the door, the latch lever is not located on the back side of the operation handle, and is projected outward from the end of the operation handle. The entire length of the case is correspondingly increased, and the material cost for manufacturing increases.

Further, in this locking handle device, since the entire receiver is peeled off and fixed to the outer surface of the edge frame of the front opening of the box body, it prevents mischief and unauthorized unlocking in the locked state. To this end, it is necessary to form a draining step portion on the edge frame portion and eliminate the approach to the receiver and interference work using the shoulder surface portion of the step portion. It was.

Furthermore, in this locking handle device, the receiving body is fixed at a specific position to the edge frame portion of the box body, and the tightening allowance cannot be adjusted, so the box body and the door are designed. When not assembled in the street-related position, there is a case where a sufficient tightening force cannot be applied between the tip hook portion of the latch lever and the receiver.
