Title:
HINGE UNIT AND HINGE STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2002/077471
Kind Code:
A1
Abstract:
A hinge unit having fewer parts and capable of being reduced in cost is obtained, and a hinge structure in which attachment of hinge unit to first and second casings is easy is obtained. When a button (50) is pressed, an actuator (72) which engages a joint section (34) slides to release the engaging recess (92) of the actuator (72) from the state of engagement with the engaging projection (90) of a stopper (84). Thereby, a sub-cam (64) is rotated by the twist force of a coil spring (62), opening a monitor section having a cam body (94) fixed thereto through the actuator (72) engaging the sub-cam (64). On the other hand, the cam body (94) is reversely rotated for the engaging recess (92) to reach a position where it is engageable with the engaging projection (90), whereupon the button (50) together with the joint section (34) is pushed out to its original position by a restoring force provided by compression of the coil spring (62). Thus, the single coil spring (62) provides a plurality of different functions, whereby the number of parts of the hinge unit (10) can be reduced.
