Patent ID: 7832240

Claim:
A lid lock device for locking a lid which is mounted in a box and which is opened and closed, the lock device comprising: a housing fixed to the lid; a hook member including: an operating portion formed to be pushed into an operation direction; a base element extending from the operating portion to enter inside the housing and to slide along the operation direction with the operating portion; a raised portion formed on the based element; and a hook portion extending from the base element to be brought into engagement with and disengagement from a lock portion provided on the box; an elastic biasing unit biasing the base element of the hook member outward the housing so that the hook portion of the hook member is brought into engagement with the lock portion; a control member including a peripheral wall defining an inner space thereinside and being slidably supported on the housing to include the raised portion of the hook member inside the inner space; and a translating unit configured to translate the control member between: a closing corresponding position where the hook member is inhibited to be pushed into the operating direction; and an opening corresponding position where the hook member is allowed to be pushed into the operating direction, wherein the peripheral wall of the control member includes: a first wall at a side far away from the operating portion, the first wall extending in a perpendicular direction to the operation direction to block the raised portion from passing therethrough; a second wall at a side proximate the operating portion, the second wall extending in the perpendicular direction to block the raised portion from passing therethrough; and a recessed portion formed on the first wall to allow the raised portion to pass therethrough in the operation direction, wherein when the control member is translated to the closing corresponding position by the translating unit, the recessed portion comes to a position where the raised portion is brought into abutment with other portions of the first wall than the recessed portion so as to prevent the operating portion from being operated, and wherein when the control member is translated to the opening corresponding position by the translating unit, the recessed portion comes to a position where the raised portion is made to enter the recessed portion so as to enable the operating portion to be operated against a biasing force of the elastic biasing unit.
