Overhead projector support leg mechanism.

摘要

The projector includes a base including a frame having a bottom including an opening and sides disposed at right angles to the bottom. There are two doors each pivoted to the frame, the doors each being rotatable between an operational position and a storage position for closing the opening in the storage position and supporting the base in the operational position. There is a biasing member for urging the doors toward the operational position, and latches for releasably retaining the doors in the storage position. There are members for releasably retaining the doors in the operational position including two gravity cams each including a body pivotally mounted on the frame. There is a cam blade extending from the body to engage one of the doors and a weight attached to the body such that gravity acting on the weight forces the cam blade into contact with the door when the frame is positioned for operation and gravity acting on the weight retracts the cam blade from the door when the base is tipped so that the base is supported by one of its sides.
