Abstract
Abstract A housing for an apparatus such as a copier has an upper frame and a lower frame which are connected together but are separable from each other such that the upper frame is rotatable with respect to the lower frame to open and close the housing. The lower frame is provide with a handle which is normally contained in the lower frame but can be pulled out when it is desired to lift or transport the apparatus. A locking member is rotatably attached to the lower frame and is slidable engaged with a piece protruding from the upper frame such that the housing can be freely opened and closed if the handle is pushed into the lower frame but that the locking member assumes a position for securely locking the frames if the handle is pulled out of the lower frame.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
187 words
In a housing for an apparatus separable into an upper frame and lower frame which are connected to each other around a connecting axis such that said upper frame can be rotated with respect to said lower frame around said connecting axis to open and close said housing, said lower frame containing a handle which can be pulled out of said lower frame, the improvement wherein said housing further comprises a locking member in contact with both said upper frame and said lower frame, an upper part of said locking member being formed with an elongated hole, said locking member being supported by said lower frame rotatably around a supporting axis, and a sliding piece protruding from said upper frame and being slidably engaged with said locking member through said elongated hole, said locking member being adapted to rotate around said supporting axis when said handle is pulled out of said lower frame or pushed into said lower frame, and said elongated hole being formed with a notch such that said sliding piece engages with said notch when said handle is pulled out of said lower frame.
