Abstract

A side guard apparatus for a bed can be selectively depoloyed between a retracted position alongside the bed and an upright position above the support surface of the bed. A side guard member is pivotally connected to a base support member, which is pivotally connected to the side of the bed. A chain and sprocket linkage constrains rotation of the plane in which the side guard member is disposed during pivoting movement of the side guard member relative to the base support member and the pivoting movement of the base support member relative to the bed. The constant angle of orientation of the side guard member can be selectively changed. The side guard member and the base support member are locked into position and unlocked from this position by a pair of locking members resiliently urged by a pair of springs to insert their respective locking pins into openings defined in a pair of oppositely disposed mounting blocks. An alignment plate defines alignment slots which engage the locking members to ensure aligned translational movement of the locking members in a locking housing during the locking and unlocking movements of the locking members.
