Abstract
An apparatus and method for tilting a bed frame is disclosed. The apparatus raises and lowers an end of a bed frame between a horizontal position and an inclined position. The apparatus includes a power actuator connected to an extendable support bar. To raise or incline the bed, a support end of the extendable support bar contacts the floor while a lifting end raises the bed frame as the power actuator causes the extendable support bar to move from a retracted position toward an extended position. As the distance between the lifting end of the extendable support bar and the floor increases, the extendable support bar inclines the bed. To increase the rate at which the bed is inclined, ramps are placed between the extendable support bar and the bed.
Claims33
An lifting apparatus comprising:
- a support bar extendable across and connectable to a frame;
- a power actuator connected to the support bar;
- an extendable bar pivotally connected to the power actuator;
- and
- a guide bar having a ramp and constructed to engage the extendable bar, the ramp constructed to increase a distance from the extendable bar to the guide bar during extension of the extendable bar.
An bed comprising:
- a frame;
- a tilting apparatus connected to the fame and configured to lift an end of the frame, the tilting apparatus comprising:
- a transverse frame bar connected to the frame;
- a lifting actuator having a retractable shaft and connected to the transverse frame bar;
- a pair of guide rails, each having a first end connected to the transverse frame bar and a second end connected to the frame;
- a pair of pivot bars each having a first end pivotably connected to the transverse frame bar and a second end;
- and
- a cross member link having a first end pivotally connected to the second end of each of the pivot bars and a second end in contact with each of the guide rails.
A method of manufacturing a frame tilting apparatus, the method comprising the steps of:
- providing a main support bar;
- connecting an actuator having a shaft to the main support bar;
- connecting a cross member bar to the shaft, the cross member bar configured to tilt a frame as the cross member bar rotates about a first end thereof;
- and
- connecting a pair of rails to the main support bar, the pair of rails configured to guide a second end of the cross member bar as the cross member bar moves therealong.
A method of inclining a bed comprising:
- engaging a first end of an extendable bar to a guide bar fixedly attached to one end of a bed frame;
- engaging a second end of the extendable bar to a floor;
- extending the first end of the extendable bar such that the extendable bar rotates causing a distance between the first end of the extendable bar and the floor to increase;
- and
- increasing a distance between the first end of the extendable bar and the guide bar as the first end of the extendable bar moves along a ramp attached to the guide bar.
A lifting apparatus comprising:
- a support bar extendable across and connectable to a frame;
- a power actuator connected to the support bar;
- an extendable bar pivotally connected to the support bar;
- a guide bar having a ramp and constructed to engage the extendable bar, the ramp constructed to increase a distance from the extendable bar to the guide bar during extension of the extendable bar;
- and
- wherein the ramp has a flat surface mounted to the guide bar and an arcuate surface opposite thereof.
A lifting apparatus comprising:
- a support bar extendable across and connectable to a frame;
- a power actuator connected to the support bar;
- an extendable bar pivotally connected to the support bar;
- a guide bar having a ramp and constructed to engage the extendable bar, the ramp constructed to increase a distance from the extendable bar to the guide bar during extension of the extendable bar;
- a first set of wheels attached to a first end of the extendable bar and constructed to move along the guide bar;
- and
- a second set of wheels attached to a second end of the extendable bar and constructed to move along a planar surface supporting the frame.
