Title: Door handle
Inventor: YAMADA KENICHI
IPC: E05B1/00
Filed: 1995-12-12
Abstract: PROBLEM TO BE SOLVED: To reduce the material cost and an incongruous sense and a painful sense, by casting the right and left sides of a grip and the rear face so as to form a recessed part indented to the rear side and from a continuous wall pressing in and fixing a cover material at the front side opening of the recessed part. SOLUTION: The right and left side faces 2a, 2b and the rear face 2c of the grip 2 are cast so as to form a recessed part 3 indented toward the rear face and formed as a continuous wall. Then, a cover plate 4 made of not a cast material but a rolled material or the like is pressed in the opening of the front face of the recessed part 3 and the grip 2 is made hollow. In the this way, the material cost is economized by the volume corresponding to the hollow part. When the grip 2 is grasped on opening/closing the door, since the inside face of fingers or the palm of hand come in contact with the right and left side faces 2a, 2b and the rear face 2c formed as a continuous wall and there is no production or wall edges, a door handle which does not bring an incongruous sense or a painful sense can be used.
