Support structure for a surface cleaning device
Aspects of the present invention relate to a recovery tank support structure for a surface cleaning device such as an extractor. The support structure partially encircles and supports the recovery tank removably mounted to a base in order to prevent any unwanted movement of the tank or its contents during operation of the extractor. The support structure creates a void for housing the recovery tank, wherein a locking mechanism may be employed to engage the recovery tank and secure it in position. An upper portion having a handle for propelling the extractor is pivotable about the base independent of the support structure thereby allowing a user access to a wide range of pivoting motion and maneuverability during extractor operation.
1. An apparatus for cleaning a surface comprising:
a base positionable on the surface;
the base including a support structure operatively coupled to and extending from the base, the support structure forming an arch creating a void beneath the support structure and above a surface of the base;
an upper portion operatively coupled to the base, wherein the upper portion includes a handle, and wherein the upper portion is pivotally connected to the base independent of the support structure; and
a tank removably mounted to the base and located in the void between the support structure and the base, wherein the support structure engages the tank.
2. The apparatus of claim 1 , wherein the support structure at least partially encircles the tank when the tank is positioned within the void.
3. The apparatus of claim 2 , wherein the support structure and the surface of the base forms a hoop around the void.
4. The apparatus of claim 1 , wherein the base has a forward portion and a rearward portion, and wherein the tank is removable from the rearward portion.
5. The apparatus of claim 1 , wherein the support structure is configured to inhibit movement of the tank relative to the base during operation of the apparatus.
6. The apparatus of claim 1 , wherein the support structure further comprises another handle for lifting at least one of the tank and the apparatus.
7. The apparatus of claim 1 , further comprising a locking mechanism releasably coupling the tank to the support structure.
8. The apparatus of claim 1 , further comprising a nozzle, wherein the tank is a liquid recovery tank in fluid communication with the nozzle.
9. The apparatus of claim 1 , wherein the upper portion is pivotable between an upright storage position and an operating position, wherein the upper portion is maintained in an upward-extending orientation above the base in the upright storage position.
10. The apparatus of claim 9 , wherein the upper portion further comprises a yoke that partially encircles at least one of the support structure and the tank positioned on the base when the upper portion is in the upright storage position.
11. The apparatus of claim 5 , wherein the support structure is pivotable relative to the base facilitating access to the tank.
12. The apparatus of claim 5 , wherein the support structure is releasable from the base facilitating access to the tank.
13. The apparatus of claim 1 , wherein the support structure further comprises a first arm and a second arm forming at least a portion of the support structure, the first arm and the second arm being pivotably mounted to the base.
14. The apparatus of claim 13 , wherein the first arm and the second arm are operatively coupled at an upper portion of the support structure.
15. The apparatus of claim 13 , wherein at least one of the first arm and the second arm being independently moveable or removable relative to the base.
16. The apparatus of claim 1 , wherein the support structure is removable from the base.
17. The apparatus of claim 1 , wherein the support structure further comprises at least one feature selected from a group consisting of a display, an indicator, a light, and a switch.
18. The apparatus of claim 1 , wherein the support structure further comprises an airflow passageway or a fluid conduit.
