Mechanism to hold cover open or closed

摘要

As monitor 1 held by casing 3 is upwardly pushed, clamp 2 is rectilinearly moved toward push latch 4 in cooperation with rotation of the monitor 1, the monitor 1 is rotatable by claw section 2a disengaged from locking hole 1b, and a striker holding section 4a engages with striker 2b to be forced into the main body of the latch 4 to be in engagement locked position. As the opened monitor 1 is upwardly pushed, the clamp 2 is rectilinearly moved toward the latch 4 in cooperation with the rotation of the monitor 1, the holding section 4a placed in the locked position with the striker 2b is forced into the main body of the latch 4 to be in engagement-lock releasing position, and the released section 2a is urged and moved by spring 5 to lock the hole 1b to hold the monitor 1 in closed position.

主权项

1. A cover opening/closing and holding mechanism comprising:
a cover that is substantially horizontally held by a casing, and also downwardly rotated about a rotation shaft to be opened; a cover locking hole formed in a face of a rotational distal end of the cover opposite to the side where the rotation shaft is provided; a clamp on one end side of which a clamp claw section for locking the cover locking hole is formed and on the other end side of which a striker is formed, and which is held by the casing to enable a reciprocating rectilinear motion; a push latch attached to the casing and having a striker holding section for engaging with the striker, wherein in cooperation with the upward rotation movement of the cover that is in the position held by the casing, the clamp is rectilinearly moved toward the push latch to thereby disengage the clamp claw section from the cover locking hole, thus making the cover rotatable and also the striker holding section engages with the striker to be forced into the main body of the push latch to be in an engagement locked position, and further in cooperation with the upward rotation movement of the cover that is in the opened position, the clamp is rectilinearly moved toward the push latch, and the striker holding section that is in the engagement locked position with the striker is forced into a main body of the push latch to be in an engagement-lock releasing position; and an urging unit that always urges the clamp toward the cover locking hole, moves the clamp by the engagement-lock releasing position, and locks the clamp claw section in the cover locking hole to substantially horizontally hold the cover; wherein the clamp has a clamp operation section that is provided between the clamp and the cover contacts the cover to converge a rotational movement of the cover to a rectilinear movement of the clamp toward the push latch.
