Abstract
A patient support apparatus that comprises a frame and a side rail mounted to the frame. The side rail comprises a side rail body and a pair of arms mounting the side rail body for rotational movement relative to the frame. The pair of arms has a pair of upper pivot connections connected to the side rail body and a pair of lower pivot connections for mounting to the frame. The upper pivot connections engage a timing link.
Claims21
A patient support apparatus comprising:
- a frame;
- a side rail mounted to said frame, said side rail including a side rail body and a pair of arms mounting said side rail body for movement over a full range of motion relative to said frame, said pair of arms having a first pair of pivot connections directly coupled to said side rail body and a second pair of pivot connections for mounting to said frame;
- a timing link;
- and
- each of said first pair of pivot connections of said pair of arms engaging said timing link over a portion of said timing link and translating across said portion when said first pair of pivot connections are pivoted.
A patient support apparatus comprising:
- a frame;
- a side rail mounted to said frame, said side rail including a side rail body and a pair of arms, said pair of arms mounting said side rail body relative to said frame, said pair of arms having a first pair of pivot connections connected to said side rail body and a second pair of pivot connections mounted to said frame, and said side rail body having first and second movable stops;
- and
- a single damper to counterbalance the weight of the side rail to reduce the force needed to raise and to lower the side rail.
A patient support apparatus comprising:
- a frame;
- a side rail mounted to said frame, said side rail including a side rail body and a pair of arms, said pair of arms mounting said side rail body relative to said frame, said pair of arms having a first pair of pivot connections connected to said side rail body and a second pair of pivot connections mounted to said frame;
- a timing link;
- and
- each of said first pair of pivot connections of said pair of arms engaged with said timing link over a first range of motion to form a four bar linkage and disengaged from said timing link over a second range of motion to no longer form a four bar linkage.
