a sleeve extending around a longitudinal axis of the upright section and slideably engaging a surface of the coupling portion, at least a portion of the sleeve being disposed within the cavity of the coupling portion, wherein a movement of the coupling portion about the second axis of rotation causes the entire sleeve to slide in a common direction along the longitudinal axis of the upright section such that the sleeve slides towards the upright section; and
a biasing member disposed within the coupling portion, wherein the biasing member biases the upright section from the sideways position towards the centered position in response to the sleeve sliding along the longitudinal axis of the upright section.
2. The apparatus of claim 1 wherein the second axis of rotation is above the first axis of rotation.
3. The apparatus of claim 1 wherein the first axis of rotation is generally parallel to the front and the second axis of rotation is generally parallel to a forward direction of motion of the cleaning head.
4. The apparatus of claim 1 further comprising a pivot lock inhibiting the sideways pivoting of the upright section.
5. The apparatus of claim 1 further comprising a pivot limiter delimiting the sideways pivoting of the upright section to a maximum sideways pivot angle from the centered position.
6. The apparatus of claim 5 wherein the pivot limiter comprises at least a first interacting member which is engaged when the upright section is pivoted sideways to the maximum sideways pivot angle.
7. The apparatus of claim 5 wherein the pivot limiter defines a plurality of maximum sideways pivot angles.
8. The apparatus of claim 7 further comprising a selector that is adjustable to select one of the pluralities of maximum sideways pivot angles.
9. The apparatus of claim 8 wherein the selector is part of the pivot limiter.
10. The apparatus of claim 9 wherein the cleaning head comprises a first support member and the upright section comprises a second support member, each of the support members extending along the longitudinal axis and the pivot limiter is rotatably mounted to one of the support members for rotation about the longitudinal axis.
11. The apparatus of claim 10 wherein the pivot limiter comprises a plurality of first interacting members and the other of the support members comprises a second interacting member, and one of the first interacting members and the second interacting member abut when the upright section is positioned at a set variable maximum sideways pivot angle.
12. The apparatus of claim 10 wherein the pivot limiter is rotatably mounted to the second support member.
13. The apparatus of claim 11 wherein the first interacting members are arranged at various distances from the second interacting member when the upright section is in the centered position and the selector is rotatable to align one of the first interacting members with the second interacting member.
14. The apparatus of claim 11 wherein the first interacting members comprise a plurality of recesses and the selector is rotatable to align one of the recesses with the second interacting member.
15. The apparatus of claim 1 further comprising:
an airflow path extending from a dirty air inlet to a clean air outlet; and
a suction motor and an air treatment member positioned in the airflow path.
16. The apparatus of claim 15 further comprising a flexible hose defining at least a portion of the airflow path that conveys dirty air past the second axis of rotation.
17. The apparatus of claim 16 further comprising a first hollow support member pivotally connected to a second hollow support member wherein the flexible hose extends through the interior of the first and second hollow support members.
18. The apparatus of claim 17 wherein each hollow support member comprises a tubular conduit.
19. The apparatus of claim 1 , wherein the first axis of rotation is parallel with the front of the cleaning head, the second axis of rotation is transverse to the front of the cleaning head, and the longitudinal axis is transverse to both the first and second axes of rotation.
20. A surface cleaning apparatus comprising:
a cleaning head having a front, a rear, two opposed sides extending between the front and the rear, and a bottom;
a coupling portion coupled to the cleaning head, the coupling portion including a first axis of rotation and a second axis of rotation, wherein the coupling portion defines a cavity;
an upright section coupled to the coupling portion, wherein the upright section is movable about the first axis of rotation between a storage position and a rearward in-use position and is movable sideways, relative to the cleaning head, about the second axis of rotation between a centered position and a sideways position;
a sleeve extending around a longitudinal axis of the upright section and at least partially disposed within the cavity of the coupling portion, the sleeve slideably engaging a surface of the coupling portion, wherein a movement of the coupling portion about the second axis of rotation causes the sleeve to slide in a direction of the upright section and along the longitudinal axis of the upright section; and
a biasing member disposed within the coupling portion, wherein the biasing member biases the upright section from the sideways position towards the centered position in response to the sleeve sliding along the longitudinal axis of the upright section.
21. A surface cleaning apparatus comprising:
a cleaning head having a front, a rear, two opposed sides extending between the front and the rear, and a bottom;
a coupling portion having an upper support and a lower support, the lower support being coupled to the cleaning head and the upper support defining a cavity for receiving at least a portion of the lower support, wherein the coupling portion includes a first axis of rotation and a second axis of rotation;
an upright section coupled to the upper support, wherein the upright section is movable about the first axis of rotation between a storage position and a rearward in-use position and is movable sideways, relative to the cleaning head, about the second axis of rotation between a centered position and a sideways position;
a sleeve extending around a longitudinal axis of the upright section and slideably engaging a surface of the upper support, at least a portion of the sleeve being disposed within the cavity of the upper support, wherein a movement of the coupling portion about the second axis of rotation causes the sleeve to slide in a direction of the upright section and slide parallel to the longitudinal axis of the upright section; and
a biasing member disposed within the coupling portion, wherein the biasing member biases the upright section from the sideways position towards the centered position in response to the sleeve sliding along the longitudinal axis of the upright section.
