Abstract

An example of a surface cleaning head may include a main body, a neck pivotally coupled to the main body, a stabilizer, and a linkage pivotally coupled to the main body and the stabilizer. The linkage may be configured to cause the stabilizer to transition between an extended position and a retracted position in response to a pivotal movement of the neck.

First claim

What is claimed is:

1. A surface cleaning head comprising:
a main body;
a neck pivotally coupled to the main body and configured to transition between a storage position and an in-use position, wherein the neck is substantially upright in the storage position and the neck is reclined in the in-use position;
a plurality of stabilizers; and
a plurality of linkages pivotally coupled to the main body, each linkage being pivotally coupled to a corresponding one of the plurality of stabilizers, wherein each linkage is configured to cause the corresponding stabilizer to transition between an extended position and a retracted position in response to a pivotal movement of the neck, each linkage including a pivot arm and a plunger, the pivot arm defining a channel for receiving the plunger,
wherein each stabilizer extends along a respective one of a first axis and a second axis;
wherein the first axis extends transverse to the second axis such that a separation distance between the stabilizers increases with increasing distance from the main body;
wherein the plurality of stabilizers are in the extended position when the neck is in the storage position and the plurality of stabilizers are in the retracted position when the neck is in the in-use position;
wherein in the extended position the plurality of stabilizers engage a surface and in the retracted position the plurality of stabilizers are out of engagement with the surface.

2. The surface cleaning head of claim 1 , wherein the neck includes a protrusion configured to engage at least a portion of at least one linkage of the plurality of linkages, the protrusion being configured to urge the at least one linkage to pivot in response to the pivotal movement of the neck.

3. The surface cleaning head of claim 1 , wherein the plunger is configured to slide within the channel in response to the pivotal movement of the neck.

4. The surface cleaning head of claim 1 , wherein at least one stabilizer of the plurality of stabilizers includes a wheel.

5. The surface cleaning head of claim 1 , wherein the main body includes an opening from which at least one stabilizer of the plurality of stabilizers extends.

6. The surface cleaning head of claim 5 , wherein the opening is disposed between a top surface of the main body and a main wheel.

7. The surface cleaning head of claim 6 , wherein at least a portion of at least one stabilizer of the plurality of stabilizers extends over at least a portion of the main wheel.

8. A vacuum cleaner comprising:
a wand; and
a surface cleaning head including:
a main body;
a neck configured to receive the wand, the neck pivotally coupled to the main body such that the neck is configured to transition between a storage position and an in-use position, wherein the neck is substantially upright in the storage position and the neck is reclined in the in-use position;
a plurality of stabilizers; and
a plurality of linkages pivotally coupled to the main body, each linkage being pivotally coupled to a corresponding one of the plurality of stabilizers, wherein each linkage is configured to cause the corresponding stabilizer to transition between an extended position and a retracted position in response to a pivotal movement of the neck, each linkage including a pivot arm and a plunger, the pivot arm defining a channel for receiving the plunger,
wherein each stabilizer extends along a respective one of a first axis and a second axis;
wherein the first axis extends transverse to the second axis such that a separation distance between the stabilizers increases with increasing distance from the main body;
wherein the plurality of stabilizers are in the extended position when the neck is in the storage position and the plurality of stabilizers are in the retracted position when the neck is in the in-use position;
wherein in the extended position the plurality of stabilizers engage a surface and in the retracted position the plurality of stabilizers are out of engagement with the surface.

9. The vacuum cleaner of claim 8 , wherein the neck includes a protrusion configured to engage at least a portion of at least one linkage of the plurality of linkages, the protrusion being configured to urge the at least one linkage to pivot in response to the pivotal movement of the neck.

10. The vacuum cleaner of claim 8 , wherein the plunger is configured to slide within the channel in response to the pivotal movement of the neck.

11. The vacuum cleaner of claim 8 , wherein at least one stabilizer of the plurality of stabilizers includes a wheel.

12. The vacuum cleaner of claim 8 , wherein the main body includes an opening from which at least one stabilizer of the plurality of stabilizers extends.

13. The vacuum cleaner of claim 12 , wherein the opening is disposed between a top surface of the main body and a main wheel.

14. The vacuum cleaner of claim 13 , wherein at least a portion of at least one stabilizer of the plurality of stabilizers extends over at least a portion of the main wheel.

15. A surface cleaning head comprising:
a main body;
a neck pivotally coupled to the main body and configured to transition between a storage position and an in-use position, wherein the neck is substantially upright in the storage position and the neck is reclined in the in-use position;
a plurality of stabilizers; and
a plurality of linkages, each linkage configured to cause a corresponding one of the plurality of stabilizers to transition between an extended position and a retracted position in response to a pivotal movement of the neck, each linkage including a pivot arm pivotally coupled to the main body and a plunger slidably coupled to the pivot arm,
wherein each stabilizer extends along a respective one of a first axis and a second axis;
wherein the first axis extends transverse to the second axis such that a separation distance between the stabilizers increases with increasing distance from the main body;
wherein the plurality of stabilizers are in the extended position when the neck is in the storage position and the plurality of stabilizers are in the retracted position when the neck is in the in-use position;
wherein in the extended position the plurality of stabilizers engage a surface and in the retracted position the plurality of stabilizers are out of engagement with the surface.

16. The surface cleaning head of claim 15 , wherein each plunger is pivotally coupled to a corresponding stabilizer.
