HINGE DEVICE
Document Type and Number:
WIPO Patent Application WO/2004/015233
Kind Code:
A1
Abstract:
A hinge shaft (3) is turnably installed in an opening in a receiving hole (21) in a hinge main body (2). A piston (5) is installed in the receiving hole (21) so that it is movable axially of the receiving hole (21). The piston (5) is linearly urged toward the hinge shaft (3) by a coil spring (6) and turnably urged in the direction of arrow (X). When the hinge shaft (3) is turned through 90°from the initial turning position in the direction of arrow (X), the piston (5) is moved from the initial position toward the hinge shaft (3) by a coil spring (6) until it reaches the release position. The piston (5) is held non-turnable with respect to the hinge main body (2) until it reaches the release position after starting from the initial position, and when it reaches the release position, it is made turnable in the direction of arrow (X). Thereby, when the piston (5) reaches the release position, the hinge shaft (3) is turned by the coil spring (6) from the 90°-turned position to a predetermined self-standing position.
