Abstract
A bed lifting apparatus comprising a base and a support frame connected by at least one linkage arm, the at least one linkage arm including at least one biasing arrangement arranged to maintain the base and the support frame in a spaced apart relationship, wherein, in use, when a bed is located on the support frame, the bed is maintained in a spaced apart relationship from a floor surface.
Claims26
A bed lifting apparatus comprising:
- a base and a support frame connected by at least one linkage arm;
- and
- the at least one linkage arm including at least one biasing arrangement arranged to maintain the base and the support frame in a spaced apart relationship;
- wherein, in use, when a bed is located on the support frame, the bed is maintained in a spaced apart relationship from a floor surface;
- and
- wherein the biasing arrangement includes at least one resilient member arranged to maintain the base and the support frame in the spaced apart relationship;
- and
- wherein the resilient member includes at least one torsion spring and at least one gas spring arranged to cooperate to maintain the base and the support frame in the spaced apart relationship;
- and
- wherein the at least one torsion spring is arranged to release potential energy in a rotational manner to thereby effect rotation of the at least one linkage arm.
