IPC: F16C11/10
Filed: 1991-12-20
Abstract: PURPOSE:To lock a movable shaft formed at its outer peripheral surface with a thread part, at an arbitrary position by threadedly engaging a pair of nut members with the thread part, and by urging the pair of nut members by an urging means so that they are separated from each other. CONSTITUTION:A shaft lock device adapted to be incorporated to, for example, a lap-top type personal computer, includes a bracket 5 attached to the personal computer body, and a movable shaft 2 is attached to a display panel by means of a support part 7. Further, when the display panel is opened relative to the body, the movable shaft 2 is rotated, relative to the nut members 3.
