[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat handle for mounting to a door which opens and closes with respect to a fixed frame.

[0002]

2. Description of the Related Art Conventionally, a frame member to be attached to a door, a handle that can be fitted into and detached from a front concave portion provided on the frame member, and a locking member such as a claw fitting for a fixed frame connected to the handle at the front surface of the frame member. A flat handle composed of a rotating shaft having the above-mentioned mounting means is well known. For example, one end of the handle is pivotally supported at one end of the rotation shaft, and the handle is raised from the frame member recess in a plane perpendicular to the door, and then the handle is moved right or left around the rotation shaft. In some cases, when the pawl is rotated in a plane parallel to the door, the claw fitting is engaged with and disengaged from the fixed frame.

If the door is relatively large and the claw fitting is large, or if the door is tightly sealed to the fixed frame and the movement of the claw fitting is accompanied by a large frictional force, the handle may be used. The torque when rotating is increased. In that case, using the known flat handle,
The force concentrates on the shaft supporting portion between the handle and the rotating shaft, which causes a problem that the portion is easily damaged. To avoid this, if the shaft and bearing of the part are made large, the surrounding parts become abnormally large,
Along with this, there arises a problem that a large mounting space is required for the flat handle.

[0004] In view of the above, the present invention provides a handle provided with a shaft, and fitting the shaft so as to rotate integrally with a rotation shaft on which a claw fitting is mounted in a circumferential direction.
