Abstract

Disclosed herein is an apparatus for moving an item. The apparatus comprises a mounting portion for mounting the apparatus to a surface, a platform configured to receive the item thereon, extendable arms configured to extend away from the mounting portion, wherein the platform is moveable between a storage position above the surface and an accessible position away from the surface, lifting assemblies that join opposing sides of the platform to a respective extendable arm, the lifting assemblies being configured to raise and lower the platform relative to the extendable arms whilst in the accessible position, and a driver operable to raise and lower the platform. At least one of the lifting assemblies comprises three arms, at least one arm being a driven arm that is driven by the driver whereby the platform is raised or lowered, and another are being a stabilising arm that is configured to move synchronously with the driven arm whereby the platform is stabilised.

Claims (27)

1. An apparatus for moving an item, the apparatus comprising:

a mounting portion for mounting the apparatus to a surface;

a platform configured to receive the item thereon;

extendable arms configured to extend away from the mounting portion, wherein the platform is movable between a storage position above the surface and an accessible position away from the surface;

lifting assemblies that join opposing sides of the platform to a respective extendable arm, the lifting assemblies being configured to raise and lower the platform relative to the extendable arms whilst in the accessible position; and

a driver operable to raise and lower the platform,

wherein at least one of the lifting assemblies comprises three arms, each arm extending between the platform and the extendable arm, at least one arm being a driven arm that is driven by the driver whereby the platform is raised or lowered, and another arm being a stabilising arm that is configured to move synchronously with the driven arm whereby the platform is stabilised,

wherein an upper portion of each arm is pivotally connected to the extendable arm, and a lower end of each arm is pivotally connected to the platform, and

wherein the stabilising arm and one of the other arms in the at least one of the lifting assemblies are pivotally connected intermediate their ends.

2. The apparatus of claim 1 , wherein a proximal end of the stabilising arm is configured to slide along the extendable arm as the platform is raised and lowered.

3. The apparatus of claim 2 , wherein the proximal end of the stabilising arm is configured to slide along the extendable arm in a direction towards the mounting portion as the platform is raised.

4. The apparatus of claim 2 , wherein a distal end of the stabilising arm is pivotally fixed to the side of the platform.

5. The apparatus of claim 1 , wherein two of the arms in the at least one of the lifting assemblies are driven arms that are driven by the driver.

6. The apparatus of claim 5 , wherein distal ends of the driven arms are configured to slide along the side of the platform as the platform is raised and lowered.

7. The apparatus of claim 5 , wherein the driver is attached to proximal ends of the driven arms.

8. The apparatus of claim 5 , wherein the driven arms are pivotally fixed to the extendable arms at a pivot intermediate their proximal and distal ends.

9. The apparatus of claim 8 , wherein the driven arms are curved such that their proximal ends are orientated towards the driver.

10. The apparatus of claim 9 , wherein the driven arms are curved at the pivot.

11. The apparatus of claim 1 , wherein the driver is a linear actuator.

12. The apparatus of claim 1 , wherein the driver is electrically actuated.

13. The apparatus of claim 1 , wherein the apparatus comprises two lifting assemblies that join opposing sides of the platform to respective extendable arms, each lifting assembly comprising three arms, each arm extending between the platform and the extendable arm, at least one arm being a driven arm that is driven by the driver whereby the platform is raised or lowered, and another arm being a stabilising arm that is configured to move synchronously with the driven arm whereby the platform is stabilised.

14. The apparatus claim 1 , wherein the extendable arms comprise one or more telescopic arms.

15. The apparatus of claim 14 , wherein the extendable arms comprise inner, intermediate and outer telescopic arms.

16. The apparatus of claim 15 , wherein proximal ends of the arms of the lifting assemblies are joined to the inner telescopic arms.

17. The apparatus of claim 1 , wherein the apparatus comprises two extendable arms and the platform is configured to be positioned therebetween.

18. The apparatus of claim 1 , wherein a width and/or length of the platform is adjustable.

19. A kit of parts which, when assembled is the apparatus of claim 1 .
