Abstract

An arrangement of a wheelchair with a movable seat and leg rest and a bed equipped with transfer apparatus including rollers, a movable sheet, a lift member, and a control system for transporting an invalid comfortably across the bed to a sitting position on the wheelchair.

Claims

1. An invalid transfer arrangement comprising:

a bed with a foot end and a head end;

said bed having a mattress, a roller at said head end, a roller at said foot end, and a transport sheet extending across said mattress and fastened to each roller, said sheet being partially rolled on each roller;

a wheelchair positioned at said foot end of the bed;

said wheelchair having a frame, a seat, a removable back rest and a leg rest;

said leg rest being movable from a seating position sloping down from said seat to a substantially level transfer position above said seat;

a spring connected to said frame and said leg rest for forcing said leg rest down to said seating position;

hook means positioned at the back of said wheelchair;

said hook means being coupled to said leg rest, said leg rest being movable from said seating position to said transfer position by pulling said hook means;

a bar adjacent and parallel to said foot end of said bed;

a linear actuator on said bed and pivotably connected to said bar, said bar being extendable from said bed by extending said actuator a predetermined distance, said bar being raisable by further extension of said actuator;

said actuator being retractable for lowering said bar to capture said hook means, for pulling said wheelchair firmly against said bed, and for acting against said spring and raising said leg rest to said transfer position;

said actuator being extendable for lowering said leg rest and moving said bar out, up and free of said hook means.

2. An invalid transfer arrangement comprising:

a bed with a foot end and a head end;

said bed having a mattress, a roller at said head end, a roller at said foot end, and a transport sheet extending across said mattress and fastened to each said roller, said sheet being partially rolled on each said roller;

a wheelchair positioned at said foot end of the bed;

said wheelchair having a seat, a frame, a removable back rest, and a leg rest;

said seat being pivotally connected to said frame and said leg rest;

said leg rest being movable from a seating position sloping down from said seat to a substantially level transfer position above said seat;

said seat rotating pivotally when said leg rest moves to said transfer position;

a linear actuator on said bed;

connecting means for removably connecting said actuator to said wheelchair; and

coupling means between said leg rest and said actuator for moving said leg rest between said seating position and said transfer position by said actuator without lifting said wheelchair.

3. An invalid transfer arrangement comprising:

a bed;

a wheelchair positioned at a foot end of said bed;

said wheelchair having a seat, a removable back, a movable leg rest, and hook mean coupled to said leg rest;

means on said bed for engaging and pulling said hook means to raise said leg rest and move said leg rest over said seat for transporting a person from said wheelchair onto said bed.

4. An invalid transfer arrangement comprising:

a bed;

a wheelchair positioned at a foot end of said bed;

said wheelchair having a seat pivotally connected to said wheelchair;

bed attaching means connected to said seat;

said bed having wheelchair connecting means for connecting to said bed attaching means;

a source of mechanical power on said bed for pulling said wheelchair connecting means when connected to said bed attaching means to pull said wheelchair against said bed and pivot said seat for moving a person from a sitting position on said wheelchair to a lying position on said bed.

5. An invalid transfer arrangement comprising a bed with a foot and a head end;

said bed having a mattress, a roller at the head end, a roller at the foot end, and a transport sheet extending across said mattress and partially rolled onto each roller;

a chair positioned at the foot end of said bed;

said chair having a seat and a leg rest;

said leg rest being movable from a seating position sloping down from said seat to a substantially level transfer position above said seat;

connection means coupled to said leg rest so that by pulling on said connection means said leg rest is movable from said seating position to said transfer position;

said bed having a motor for pulling said connection means and raising said leg rest to said transfer position.

6. A method for moving a person from a seated position on a chair to a bed, comprising the steps of:

providing a chair with a seat pivotally connected to said chair;

providing bed attaching means connected to said seat in said chair;

attaching said chair to a bed with said bed attaching means; and

pulling or pushing said bed attaching means for pivoting said seat and moving the person from said chair to said bed.

7. A method of moving a person from a seated position on a chair to a bed, comprising the steps of:

providing a chair with a seat pivotally connected to said chair;

providing seat pivoting means connected to said seat in said chair; and

pulling or pushing said seat pivoting means for pivoting said seat and moving the person from said chair to said bed.

8. An invalid transfer arrangement comprising:

a bed with a foot end and a head end;

said bed having a mattress, a roller at said head end, a roller at said foot end, and a transport sheet extending across said mattress and fastened to each said roller, said sheet being partially rolled on each said roller;

a wheelchair positioned at said foot end of the bed;

said wheelchair having a seat, a frame, a removable back rest, and a leg rest;

said seat being pivotally connected to said frame and said leg rest;

said leg rest being movable from a seating position sloping down from said seat to a substantially level transfer position above said seat;

said seat rotating pivotally when said leg rest moves to said transfer position;

a linear actuator on said bed;

connecting means for removably connecting said actuator to said wheelchair; and

coupling means between said leg rest and said actuator for moving said leg rest between said seating position and said transfer position by said actuator without lifting said wheelchair;

said coupling means having a driving member connected to said leg rest and said seat;

a flexible cable wound around said driving member and fastened to one end of said driving member, said flexible cable being removably connected to said actuator, said actuator having actuating motion for rotating said driving member and moving said leg rest and said seat.
