Abstract

A transfer device for moving a personal storage container from a storage position at the rear of a wheelchair to a deployed position at a side of the wheelchair. The device includes a bracket adapted to be mounted to the backrest frame and a swivel mechanism with a first hinge leaf rotationally mounted to the bracket for rotation about a first axis and a second hinge leaf rotationally mounted to the first hinge leaf about a second axis spaced apart from the first axis. The second hinge leaf has a portion adapted to mount the personal storage container. The portion adapted to mount the personal storage container moves along an arc contained within a plane between the storage and the deployed positions, and the first and second axes are normal to the plane. A personal storage container assembly is also provided.

Claims

1. A wheelchair accessory comprising a transfer device for moving a personal storage container where the wheelchair includes a backrest frame having a pair of upstanding frame members, the transfer device comprising:

a pair of brackets adapted to be mounted to the pair of upstanding frame members;

a first arm mounted to the brackets;

a swivel mechanism including a first hinge leaf rotationally mounted to the first arm for rotation about a first axis, and a second hinge leaf rotationally mounted to the first hinge leaf about a second axis spaced apart from the first axis, the second hinge leaf having a portion adapted to mount the personal storage container;

a second arm connected to a free end of the second hinge leaf;

wherein the swivel mechanism is movable between a storage position at the rear of the backrest and a deployed position parallel to a side of the wheelchair;

wherein the second arm extends parallel to the side of the wheelchair when the swivel mechanism is in the storage position;

wherein the second hinge leaf is movable along an arc contained within a plane between the storage and the deployed positions when the second arm is retrieved by a user in the wheelchair.

2. The wheelchair accessory as defined in claim 1, wherein the arc defines an angle of 270°

.

3. The wheelchair accessory as defined in claim 1, wherein the first arm is mounted to the pair of brackets, and the first arm is adjustable in length between the brackets to accommodate different wheelchair width dimensions.

4. The wheelchair accessory as claimed in claim 3, wherein the first axis between the first arm and the first hinge leaf at one end of the first arm spaced from a respective one of the brackets.

5. The wheelchair accessory as defined in claim 4, wherein the second hinge leaf has a predetermined length suitable for mounting at least one surface of a personal storage container, and the second axis is located midway of the second hinge leaf.

6. The wheelchair accessory as defined in claim 4, wherein the second hinge leaf defines a slotted portion for supporting a container.

7. The wheelchair accessory as defined in claim 1, wherein the second arm is a pull handle is fixed at the free end of the second hinge leaf.

8. The wheelchair accessory as defined in claim 3, wherein the first arm and brackets include a pivot mechanism having a third axis parallel to the plane so that the swivel mechanism is adjustable about the third axis to change the orientation of the plane.

9. The wheelchair accessory as defined in claim 8, wherein the pivot mechanism includes a first tab mounted to a bracket in a second plane normal to the plane, a second tab in a plane parallel to the second plane and rotationally engaged to the first tab for rotation about the third axis, and a movement adjustment member interconnecting the first and second tabs for adjusting and limiting the rotation about the third axis.

10. A personal storage container assembly for a wheelchair movable between a storage position at the rear of a wheelchair to a deployed position at a side of the wheelchair where the wheelchair includes a backrest frame with a pair of spaced apart upstanding frame members, the assembly comprising a personal storage container and a transfer device, the transfer device including a first arm with a bracket for each of the upstanding frame members, and a swivel mechanism including a first hinge leaf rotationally mounted to the first arm for rotation about a first axis, and a second hinge leaf rotationally mounted to the first hinge leaf about a second axis spaced apart from the first axis, the second hinge leaf mounting the personal storage container, a second arm fixed to an end of the second hinge leaf and extending along the side of the wheelchair when the storage container is in the storage position, the swivel mechanism being movable between the storage position and the deployed position on urging of the second arm by a user in the wheelchair, the personal storage container moving along an arc contained within a plane between the storage and the deployed positions, the first and second axes being normal to the plane.

11. The assembly as defined in claim 10, wherein the arc defines an angle of 270°

.

12. The assembly as defined in claim 10, wherein the assembly is releasably mounted to the backrest.

13. The assembly as defined in claim 10, wherein the brackets include a pivot assembly having a third axis parallel to the plane so that the swivel mechanism is adjustable about the third axis to change the orientation of the plane.

14. The assembly as defined in claim 10 wherein the container is a soft walled bag having a front wall and a rear wall, the rear wall facing the backrest, the rear wall having a sleeve extending widthwise of the assembly and the second hinge leaf having an arm extending within the sleeve to mount the bag to the transfer device.
