Hydrotherapy devices

DETAILED DESCRIPTION I claim: 1.
A hydrotherapy device comprising: a generally tub-shaped lower housing having an upper rim; a generally tub-shaped upper housing of resilient material and nested within said lower housing and having an upper periphery matable with said rim, the bottom wall of said upper housing being spaced from the bottom wall of said lower housing when said housings are nested together; means for fastening said rim to said periphery as the only support of said upper housing; and vibratory means secured to a wall of said upper housing and disposed between the respective walls of said housings.
2.
A device as defined in claim 1 in which said bottom wall of said upper housing slants in one direction relative to said rim.
3.
A device as defined in claim 1 in which said vibratory means is secured to said bottom wall of said upper housing.
4.
A device as defined in claim 1 in which said vibratory means includes an electric motor the rotating shaft of which is eccentrically weighted and which further includes a plurality of supports securing said vibratory means directly to said wall and mutually spaced from one another.
5.
A device as defined in claim 4 in which there are three of said supports disposed in triangular relationship.
6.
A device as defined in claim 1 which further includes manually removable means for locking said housings together and thereby restricting relative movement of the walls of said housings and of said vibratory means.
7.
A device as defined in claim 1 in which said periphery includes a flange and in which switch means, for controlling operation of said vibratory means, are mounted in said flange.
8.
A device as defined in claim 7 in which said switch means are ensealed by a water-impervious material.
9.
A device as defined in claim 1 which further includes: a multi-conductor electric cable for supplying power to said vibratory means; a removable segment of said lower housing having an opening admitting said cable; means secured to said segment for captivating said cable; and means for securing said segment in said opening with said segment serving to release strain in said lower housing exerted by tension in said cable
