Abstract
A lock device includes a base, a first rotation member, a second rotation member, a first elastic member, and a second elastic member. Protrusions are provided on one of the base and one of the first rotation member and the second rotation member. The protrusions are protruded in a direction parallel to the rotation axis of the first rotation member. An end of one of the first elastic member and the second elastic member is fixed to the protrusions. The protruding length in the rotation axis direction of the protrusions is longer than the length in the rotation axis direction of one of the first elastic member and the second elastic member.
Claims5
A lock device comprising:
- a plate-shaped base having a front surface and a back surface;
- a first rotation member and a second rotation member, which are provided on the front surface of the base and rotated around a rotation axis parallel to each other, wherein at least a portion of the first rotation member and the second rotation member contacts each other, so that the relative rotation in at least one direction of the first rotation member and the second rotation member is able to be locked;
- a striker, which is able to be moved in a striker receiving portion provided on at least one of the first rotation member and the second rotation member;
- a first elastic member, which is provided in a space between the base and the first rotation member to be elastically deformable;
- a second elastic member, which is provided in a space between the base and the second rotation member to be elastically deformable,
- wherein, when the relative rotation between the first rotation member and the second rotation member is locked, the lock device becomes a locked state where the striker is prevented from being detached from the striker receiving portion,
- wherein, when the locking of the relative rotation between the first rotation member and the second rotation member is released, the lock device becomes an unlocked state where the striker is allowed to be detached from the striker receiving portion,
- wherein the first elastic member applies a force to the first rotation member to rotate the first rotation member in one direction around the rotation axis,
- wherein the second elastic member applies a force to the second rotation member to rotate the second rotation member in one direction or the other direction around the rotation axis,
- wherein a protrusion is provided on one of the base and one of the first rotation member and the second rotation member, the protrusion being protruded in a direction parallel to the rotation axis and an end of one of the first elastic member and the second elastic member being fixed to the protrusion, and
- wherein a protruding length in the rotation axis direction of the protrusion is longer than a length in the rotation axis direction of one of the first elastic member and the second elastic member.
