Description

Flat Handle Unit {FLUSH HANDLE ASSEMBLY}

The present invention relates to a flat handle device in which the handle is normally immersed in the case, the handle is swung out of the case when the door is opened, and the fixing plate on the rear side of the case is driven to the unlocked position.

In the conventional flat handle disclosed in Japanese Unexamined Patent Publication No. 45-28779, the proximal end of the handle that rotates in a plane perpendicular to the front of the case is pivotally attached to the left and right side walls of the case by the pivot axis in the left and right directions, The fixed plate that rotates in parallel planes is pivotally attached to the back of the case by the pivot axis in the front-rear direction, and the spring is inserted between the handle and the case to rotate and press the handle in the protruding direction and the immersion direction. The operation projections, which are subsequently installed, are inserted into the manual holes provided on the fixing plate, and when the handle is pulled, the hole edges of the manual holes are pressed on the outer surface of the operation protrusion to rotate the fixing plate.

In such a flat handle device, since the economical efficiency of manufacturing is good, the case and the handle are formed by a zinc die cast or an aluminum die cast, and the fixed steel plate is press-formed by a steel plate in order to secure this strength as a locking member. There is a big difference in the hardness of the fixing plate and the handle.

Therefore, while repeating the rotation operation of the fixing plate by pressurizing the operating protrusion of the handle, the frictional damage of the outer circumferential surface of the operating protrusion attached to the hole edge of the manual hole of the fixing plate gradually grows, The hole edge of the manual hole is dug into the friction damage portion deeply formed in the V-groove, and the fixing plate is not rotated.

In such a state, when the handle is strongly pulled or pressed, and the fixing plate is forcibly rotated, excessive bending force acts on the operation protrusion as the arm of the handle as the arm of the lever. The protrusions are broken and damaged.

Even if the material hardness of the handle and the fixing plate is equal or approximate, sometime the friction damage on the outer surface of the operation projection is inevitable due to the hole edge of the manual hole, and the fixing plate and the operation projection of the handle Lifting accidents are reported.

Therefore, an object of the present invention is to provide a flat handle device that can be smoothly operated over a long period of time without the indentation of the fixing plate by the repeated use of the handle.
