Patent ID: 8403374

Claim:
A lock system comprising: a support structure including a storage space; a lid element pivotally supported to rotate on the support structure so as to close the storage space; a slide pin supported on the lid element so as to be axially movable, the slide pin including one end to be engaged with and disengaged from the support structure, and an other end; a spring member that biases the slide pin so as to be locked on the support structure; an operation handle pivotally supported on the lid element; a cylindrical portion connected to the operation handle; a cam member including one end inserted into the cylindrical portion and an other end connected to the other end of the slide pin; and a cam mechanism provided between the cylindrical portion and the cam member to transform a swinging motion of the operation handle into an axial movement of the slide pin, wherein the other end of the slide pin includes: a post portion projecting in an axial direction of the slide pin; and double lateral projecting portions projecting to both sides from the post portion so as to form an edge on the other end of the slide pin; and wherein the other end of the cam member includes: an axial recess portion configured to open so as to receive the post portion along an insertion direction which is perpendicular to the axial direction; lateral recess portions formed by extending a width of the axial recess portion at a lengthwise intermediate position thereof to receive the double lateral projecting portions to thereby restrict movement of the slide pin in the axial direction; and an elastic engagement piece provided inside the axial recess portion to be brought into engagement with a distal end of the slide pin to thereby urge the slide pin in the axial direction and restrict a movement of the slide pin in the insertion direction.
