Abstract
Abstract This invention relates to a spa which may be used in an in-ground or above ground swimming pool or other liquid containing structure. The spa includes a frame capable of supporting a person or persons and comprising one or more frame members having a plurality of apertures or perforations. There is also included conveying means connectable to a liquid source such as the outlet pipe of a swimming pool for conveying liquid to the apertures or perforations included in the spa frame whereby liquid may be expelled under pressure of a person or persons supported by the frame. Suitably there is also included aerating means associated with the conveying means for aerating liquid before being expelled from the apertures or perforations in the spa frame.

Claim 1
Independent Claim
162 words
A moveable spa which may be used in an in-ground or above-ground water containing structure such as a swimming pool comprising a spa frame having flotation means capable of supporting at least one person and having at least two frame members each provided with a plurality of apertures, a pair of conveying conduits connectable to a water source for conveying water to the apertures in each frame member respectively of said spa frame, a valve housing associated with said conveying conduits and through which said liquid passes from said liquid source including a pair of valve members for controlling the flow of water to each conduit and plug means located in said spa frame for blocking passage of water to separate said two frame members wherein said apertures in each frame member are so oriented and arranged that upon selective actuation of said valve members said spa frame may be propelled in a forward or reverse direction or adopt a stationary position.
Claim 2
Dependent Claim
162 words
A moveable spa which may be used in an in-ground or above-ground water containing structure such as a swimming pool comprising a spa frame having flotation means capable of supporting at least one person and having at least two frame members each provided with a plurality of apertures, a pair of conveying conduits connectable to a water source for conveying water to the apertures in each frame member respectively of said spa frame, a valve housing associated with said conveying conduits and through which said liquid passes from said liquid source including a pair of valve members for controlling the flow of water to each conduit and plug means located in said spa frame for blocking passage of water to separate said two frame members wherein said apertures in each frame member are so oriented and arranged that upon selective actuation of said valve members said spa frame may be propelled in a forward or reverse direction or adopt a stationary position.
Claim 3
Dependent Claim
31 words
A moveable spa as set forth in claim 1 further comprising aerating means associated with said valve housing for aerating water as it passes to said apertures from said water source.
Claim 4
Dependent Claim
37 words
