Guardrail assembly for mounting on one side of a hospital bed having a horizontal bed frame. The assembly has a guardrail which is movable between a raised protection position and a lowered retracted position. It further has, at each end of the bed, an upward bracket; a link connected at one end to one end of the rail and pivoted adjacent the other end to the bracket so that it can move in a vertical plane, motion of both links thus causing movement of the rail between the aforesaid two positions. The assembly further provides for a pin locking mechanism on each bracket including a pin which is resiliently biassed toward the bracket and the locking end of the link for insertion in a hole of the bracket and a hole of the locking end when the guard is in the raised protection position and the holes register whereby to hold the guard in the raised position. Additionally, the pin of one of the locking mechanism has a knob at the end which is suitable to withdraw it from the hole of the link with which it cooperates. Finally, a linkage interconnects the pin locking mechanisms to cause simultaneous engagement and disengagement of the pins with the locking end holes by actuation of the manually operable knob. |
