DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat handle device in which an operating handle is immersed in a main body case when not in use, and is held at a buried position by a latch body interlocking with a rotor of a lock unit.

[0002]

2. Description of the Related Art In a flat handle device, when a key is inserted into a lock unit and a rotor is turned in a predetermined direction, a latch body retreats to a standby position, and a locking projection at a tip of the latch body is moved to a tip of an operation handle. Escape from the locking recess of the part. As a result, the operation handle released from the restraint rotates by the bias of the spring, and projects from the main body case to a grippable position.
After the operation handle is further pulled out of the main body case and rotated, or at the same position as long as the initial projection angle is sufficient, the rotation is centered on the locking shaft, and the stopper plate is detached from the metal receiving portion on the fixed frame side. Let it.

However, in the actual use state of the flat handle device, the catch plate is strongly pressed against the metal receiving portion in order to attract the door to the fixed frame and sufficiently compress the waterproof packing. Therefore, in the locked state, a rotational moment acts on the operation handle due to this approaching reaction force, and the side surface of the operation handle is pressed against the inner wall surface of the main body case, and a large frictional force acts between the two. I have.

When the frictional force is greater than the resilience of the rotation urging spring of the operation handle, the operation handle is not moved even if the rotor of the lock unit is turned to the unlock position to move the latch body to the release position. It remains in the immersive position. The only way to forcibly pull out the operation handle from the outside of the main body case is to insert the tip of the driver into the gap between the main body case and the operation handle and go out. Such a gouge damages the main body case and the operation handle, causes peeling of the painted surface and the plated surface, and causes corrosion.

[0005]

Accordingly, an object of the present invention is to provide a flat handle device capable of forcibly pushing up an operation handle from the inside of a main body case.

Therefore, the operation handle 1 is forcibly pushed up from the inside of the main body case 2 and is pushed out of the main body case 2 by overcoming the frictional force due to the above-mentioned approach.

Normally, the operation handle is formed in a trapezoidal cross section, and the contact portion between the operation handle 1 and the inner wall surface of the main body case 2 is only the front edge portion of the operation handle 1. The pushing amount is small. After the front edge portion comes out of the main body case 1, the operating handle 1 projects and rotates to a predetermined angle by the original elastic force of the biasing spring 3.

When the operating handle 1 is turned along the front of the door 28, the locking shaft 6 supported by the bearing cylinder 2a of the main body case 2 rotates, and the tip of the integrally rotated stopper plate 7 is fixed to the fixed frame. It is detached from the receiving part 27 on the body 29 side. As a result, the door 28 is unlocked from the fixed frame 29, and is opened by pulling the operation handle 1 toward the user.
