Abstract
Abstract A device for passing a treatment gas into a bathtub or similar container consisting of a grate of plastic at least the upper grate boards of which have a hollow cross section to serve as gas-conducting chambers for passing the treatment gas to and through nozzle openings which are provided in the sidewalls of the adjacent upper grate boards facing each other. The gas may be conducted from a gas source under pressure to the individual upper grate boards either through a pipe which is connected to all of the upper boards or through one of the lower cross boards which likewise has a hollow cross section and is connected by resilient plugs with axial bores to each of the upper boards.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
148 words
A gas-percolating device for therapeutic bath treatments comprising a grate consisting of a plurality of parallel upper boards laterally spaced from each other and consisting of plastic and each having a Hollow cross section so as to form a chamber, said chamber having an upper wall portion adapted to engage with and directly support a human body or body part to be treated and other wall portions with which said body is normally not capable of engaging when resting on said upper wall portion, said other wall portions having nozzle bores therein, and a plurality of lower boards extending transverse to said upper boards and secured thereto so as to connect said upper boards to each other, and gas conducting means connected to each of said upper boards for passing a treatment gas under pressure into and through each of said chambers and out of said nozzle openings.
Claim 2
Dependent Claim
148 words
A gas-percolating device for therapeutic bath treatments comprising a grate consisting of a plurality of parallel upper boards laterally spaced from each other and consisting of plastic and each having a Hollow cross section so as to form a chamber, said chamber having an upper wall portion adapted to engage with and directly support a human body or body part to be treated and other wall portions with which said body is normally not capable of engaging when resting on said upper wall portion, said other wall portions having nozzle bores therein, and a plurality of lower boards extending transverse to said upper boards and secured thereto so as to connect said upper boards to each other, and gas conducting means connected to each of said upper boards for passing a treatment gas under pressure into and through each of said chambers and out of said nozzle openings.
Claim 3
Dependent Claim
37 words
A device as defined in claim 1, in which each of said upper boards has a substantially rectangular cross section with sidewalls facing those of the adjacent upper boards, said nozzle openings being provided in said sidewalls.
Claim 4
Dependent Claim
71 words
A device as defined in claim 1, in which said gas conducting means comprise at least one of said lower boards which likewise has a hollow cross section and is adapted to conduct said gas channel means connecting the inside of said lower board to the inside of said chamber in each of said upper boards, and means for connecting said lower board to a source of treatment gas under pressure.
Claim 5
Dependent Claim
31 words
A device as defined in claim 3, in which each of said lower boards has recesses in its upper surface into each of which one of said upper boards is inserted.
Claim 6
Dependent Claim
25 words
A device as defined in claim 3, further comprising sealing means inserted around said channel means between said upper board and said gas-conducting lower board.
Claim 7
Dependent Claim
128 words
A device as defined in claim 5, in which the upper wall of said gas-conducting lower board has a plurality of apertures and the lower wall of each of said upper boards has at least one aperture in axial alignment with one of said apertures in said lower board, each of said channel means comprising a plug of a resilient material having an axial bore, said plug being adapted to be inserted into said aligned aperture of said upper and lower boards and when so inserted resiliently clamping said lower board to one of said upper boards and also compressing said sealing means between said upper and lower boards so that no gas passed into said lower board can escape to the outside except through said nozzle bores.
Claim 8
Dependent Claim
90 words
A device as defined in claim 6, in which each of said upper boards contains a plurality of reinforcing partitions dividing said chamber in said upper board into at least three adjacent longitudinal channels, said apertures in the lower walls of said upper boards through which said plugs are inserted extending only through the lower walls of the two outer channels of each upper board, said nozzle openings being provided only in the outer sidewalls of each of said outer channels facing the outer sidewalls of the adjacent upper boards.
Claim 9
Dependent Claim
20 words
A device as defined in claim 1, in which each of said upper boards contains a plurality of reinforcing partitions.
Claim 10
Dependent Claim
38 words
A device as defined in claim 8 in which said partitions divide said chamber in each of said upper boards into as least three adjacent longitudinal channels, said partitions having apertures for connecting said channels with each other.
Claim 11
Dependent Claim
55 words
A device as defined in claim 8 in which said partitions divide said chamber in each of said upper boards into at least three adjacent longitudinal channels, said nozzle openings being provided only in said other wall portions of the outer channels, and said gas conducting means being connected only to said two outer channels.
