Abstract

A foot spa tub includes a tub basin, a first magnetic drive member rotatably coupled to a drive motor, and a first casing supporting the magnetic drive member. The first casing is disposed against an exterior surface of a sidewall of the basin. A second magnetic drive member is rotatably coupled to a blade. The first and second magnetic drive members are magnetically coupled to each other so that the blade is drivingly coupled to the drive motor. A nozzle houses the second magnetic drive member and the blade. The nozzle is detachably securable to an interior surface of the sidewall by a magnetic attraction force between the first and second magnetic drive members. The nozzle is further secured in place through a fixation assembly which prevents displacement and rotation of the nozzle during operation.

Claims (47)

1. A foot spa tub, comprising:

a tub basin comprising a sidewall having an exterior surface, an interior surface, and a top edge;

a drive motor;

a first magnetic drive member rotatably coupled to the drive motor;

a first casing supporting the first magnetic drive member, the first casing disposed against the exterior surface of the sidewall of the tub basin;

a flow inducing member having at least one blade;

a second magnetic drive member rotatably coupled to the flow inducing member, the first and second magnetic drive members magnetically coupled to one another so that the flow inducing member is drivingly coupled to the drive motor;

a nozzle housing the second magnetic drive member and the flow inducing member;

a locking assembly operably associated with the nozzle for releasably securing the second magnetic drive member and the flow inducing member in the nozzle; and

a fixation assembly for detachably securing the nozzle adjacent to the interior surface, the fixation assembly comprising a sidewall portion mechanically fastened on the interior surface of the tub basin and a nozzle portion formed on the nozzle, the sidewall portion and nozzle portions being detachably secured together by a magnetic attraction force between said first and second magnetic drive members, said sidewall portion and said nozzle portion further mating members cooperating to prevent movement of the nozzle with respect to the sidewall.

2. The foot spa tub according to claim 1 , wherein the sidewall portion comprises at least a first magnet positioned adjacent to the interior surface and the nozzle portion comprises at least a second magnet positioned on the nozzle.

3. The foot spa tub according to claim 2 , wherein the second-magnet is integral with the nozzle.

4. The foot spa tub according to claim 2 , wherein the second-magnet is attached to the nozzle.

5. The foot spa tub according to claim 1 , wherein said mating members are defined by at least one projection and at least one depression respectively provided on the projection and recess portions.

6. The foot spa tub according to claim 5 , wherein the projections are formed integrally with the sidewall portion.

7. The foot spa tub according to claim 1 , wherein the sidewall portion comprises at least one depression and the nozzle portion comprises at least one projection defining said mating members.

8. The foot spa tub according to claim 7 , wherein the projections are formed integrally with the nozzle.

9. The foot spa tub according to claim 1 , wherein the sidewall portion comprises a first projection and the nozzle portion comprises a second projection.

10. The foot spa tub according to claim 9 , wherein the first projection and the second projection mate with each other to prevent movement of the nozzle.

11. A foot spa tub, comprising:

a tub basin comprising a sidewall having an exterior surface, an interior surface, and a top edge;

a drive motor;

a first magnetic drive member rotatably coupled to the drive motor;

a flow inducing member having at least one blade;

a second magnetic drive member rotatably coupled to the flow inducing member, the first and second magnetic drive members magnetically coupled to one another so that said flow inducing member is drivingly coupled to said drive motor;

a nozzle to house the second magnetic drive member and the flow inducing member; and

a fixation assembly for detachably securing the nozzle to the sidewall, the fixation assembly comprising a sidewall portion mechanically fixed adjacent the interior surface and a nozzle portion formed on the nozzle, the sidewall and nozzle portions cooperating to prevent movement of the nozzle with respect to the sidewall;

the sidewall portion being detachably secured to the nozzle portion by a magnetic attraction force between said first and second magnetic drive members.

12. The foot spa tub according to claim 11 , wherein the sidewall portion comprises at least a first arcuate magnet and the nozzle portion comprises at least a second arcuate magnet complementary to the first arcuate magnet.

13. The foot spa tub according to claim 12 , wherein the first arcuate magnet is integral with a plate attached to the interior surface.

14. The foot spa tub according to claim 12 wherein the second arcuate magnet is integral with the nozzle.

15. The foot spa tub according to claim 11 , wherein the sidewall portion comprises at least one projection and the nozzle portion comprises at least one depression.

16. The foot spa tub according to claim 15 , wherein the projection is integral with a plate attached to the interior surface.

17. The foot spa tub according to claim 11 , wherein the sidewall portion comprises at least one depression and the nozzle portion comprises at least one projection.

18. The foot spa tub according to claim 17 , wherein the depression is integral with a plate which is attached to the interior surface.

19. The foot spa tub according to claim 11 , wherein the sidewall portion comprises at least a first projection and the nozzle portion comprises at least a second projection.

20. The foot spa tub according to claim 19 , wherein the first projection is integral with a plate attached to the interior surface.

21. A drive assembly for circulating liquids in a foot spa tub, comprising:

a drive motor;

a first magnetic drive member rotatably coupled to the drive motor;

a first casing supporting the first magnetic drive member, the first casing adapted to be affixed against the exterior surface of a sidewall of a tub basin;

a flow inducing member having at least one blade;

a second magnetic drive member rotatably coupled to the flow inducing member, the first and second magnetic drive members magnetically coupled to one another so that the flow inducing member is drivingly coupled to the drive motor;

a nozzle to house the second magnetic drive member and the flow inducing member;

a locking assembly operably associated with the nozzle for releasably securing the second magnetic drive member and the flow inducing member in the nozzle; and

a fixation assembly for detachably securing the nozzle adjacent to the interior surface, the fixation assembly comprising a sidewall portion adapted to be mechanically fastened to the interior surface and a nozzle portion formed on the nozzle, the sidewall portion and nozzle portions being detachably secured together by a magnetic attraction force between said first and second magnetic drive members, said sidewall portion and said nozzle portion further mating members cooperating to prevent movement of the nozzle with respect to the sidewall.

22. The drive assembly according to claim 21 , wherein mating members are defined by at least one projection and at least one depression respectively provided on the sidewall and nozzle portions.
