Abstract

A vacuum cleaner may include a surface cleaning head, a wand pivotally coupled to the surface cleaning head, and a rotatable canister mount. The rotatable canister mount may include a support through which at least a portion of the wand extends such that the canister mount rotates relative to the wand in response to the wand pivoting.

First claim

What is claimed is:

1. A vacuum cleaner comprising:
a surface cleaning head;
a wand pivotally coupled to the surface cleaning head; and
a rotatable canister mount having a support through which at least a portion of the wand extends such that the rotatable canister mount rotates relative to the wand in response to the wand pivoting.

2. The vacuum cleaner of claim 1 , further comprising a pivot joint that pivotally couples the wand to the surface cleaning head.

3. The vacuum cleaner of claim 2 , wherein the pivot joint defines at least four pivot axes.

4. The vacuum cleaner of claim 2 , wherein the pivot joint includes a body swivel joint and a wand swivel joint.

5. The vacuum cleaner of claim 4 , wherein the body swivel joint includes a body swivel gimbal pivotally coupled to the surface cleaning head and defining a first body pivot axis.

6. The vacuum cleaner of claim 5 , wherein the rotatable canister mount is pivotally coupled to the body swivel gimbal and defines a second body pivot axis.

7. The vacuum cleaner of claim 4 , wherein the wand swivel joint includes a wand swivel gimbal pivotally coupled to the surface cleaning head and defining a first wand pivot axis.

8. The vacuum cleaner of claim 7 , wherein the wand swivel joint further includes a receptacle configured to receive at least a portion of the wand, the receptacle being pivotally coupled to the wand swivel gimbal and defining a second wand pivot axis.

9. The vacuum cleaner of claim 1 , wherein the wand is configured to pivot about at least a first pivot axis and a second pivot axis.

10. The vacuum cleaner of claim 9 , wherein the first pivot axis is parallel to a direction of movement of the vacuum cleaner.

11. The vacuum cleaner of claim 10 , wherein the second pivot axis is transverse to the first pivot axis.

12. An upright vacuum cleaner comprising:
a surface cleaning head;
a wand having a longitudinal axis;
a pivot joint pivotally coupling the wand to the surface cleaning head such that the wand rotates about the longitudinal axis; and
a main body movably coupled to the wand, wherein the main body moves independently of the wand such that a center of gravity of the main body rotates about the longitudinal axis of the wand to a lesser extent than the wand rotates about the longitudinal axis.

13. The upright vacuum cleaner of claim 12 , wherein the pivot joint includes a body swivel joint and a wand swivel joint.

14. The upright vacuum cleaner of claim 13 , wherein the body swivel joint includes a body swivel gimbal pivotally coupled to the surface cleaning head.

15. The upright vacuum cleaner of claim 14 , further comprising a mount configured to couple to the main body, the mount being pivotally coupled to the body swivel gimbal.

16. The upright vacuum cleaner of claim 14 , wherein the wand swivel joint includes a wand swivel gimbal pivotally coupled to the surface cleaning head.

17. The upright vacuum cleaner of claim 16 , wherein the wand swivel joint further includes a receptacle configured to receive at least a portion of the wand, the receptacle being pivotally coupled to the wand swivel gimbal.

18. A multiple axis pivot joint for a vacuum cleaner comprising:
a frame;
a wand swivel gimbal pivotally coupled to the frame;
a body swivel gimbal pivotally coupled to the frame;
a mount configured to couple to a main body of the vacuum cleaner, the mount being pivotally coupled to the body swivel gimbal, wherein the mount includes a support, the support being configured such that a wand of the vacuum cleaner is moveable relative to the support about a longitudinal axis of the wand; and
a receptacle configured to receive at least a portion of the wand of the vacuum cleaner, the receptacle being pivotally coupled to the wand swivel gimbal.

19. The multiple axis pivot joint of claim 18 , wherein the wand swivel gimbal defines a first wand pivot axis and the receptacle defines a second wand pivot axis.

20. The multiple axis pivot joint of claim 18 , wherein the body swivel gimbal defines a first body pivot axis and the mount defines a second body pivot axis.
