Patent ID: 7734218

Claim:
A cover-body locking construction, comprising: a specified housing; a frame insertable into and withdrawable from the housing; a structure supported on the frame; and a cover body shiftable between a covering position to cover at least part of the structure and an exposing position to expose the at least part of the structure to the outside by canceling the covered state with the structure withdrawn from the housing, the cover body including a locking member having a locking portion for locking the cover body set at the covering position into the frame and an operating portion for causing the locking portion to lock and unlock; wherein the housing includes a lock guiding member shaped to interlock the locking portion with the frame due to interference with the cover body and the operating portion upon inserting the frame into the housing with the structure covered by the cover body; the cover body is so mounted on the frame as to be shiftable between the covering position and the exposing position by rotating about a first shaft provided in the frame and is biased toward the exposing position by a biasing force of a first biasing member; the frame has an engaging portion engageable with the locking portion of the locking member; the locking member is shiftable between an engaging position to engage the locking portion with the engaging portion and a disengaging position to disengage the locking portion from the engaging portion by rotating about a specified second shaft and is biased toward the engaging position by a biasing force of a specified second biasing member; and the lock guiding member is so shaped as to free the locking member from being pushed after the locking member is pushed toward the engaging position while the cover member is pushed against the biasing force of the first biasing member.
