SHEET 2 OF 3 INVEN'I'ORS HANS ScH/YEDT and ALFO/VS QESI'IZRRICHFR GAS-PERCOLATING DEVICE FOR THERAPEUTIC BATH TREATMENTS The present invention relates to a gas-percolating device for therapeutic bath treatments which comprises a grate of plastic which is adapted to be placed upon the bottom of a bathtub or similar container and consists of a plurality boards which each other by lower cross boards, and means for passing a treatment gas from this grate into the bath liquid.
Such grates are usually inserted into bathtubs, foot baths or the weight of a human body or body portion to be treated and for supporting the same at a grates which are conventionally used for this purpose usually consist of boards or strips of wood which are spaced from each other sufficiently so that rigid or flexible tubes of metal, rubber or the like which may be inserted between them so that a treatment gas may be conducted through these tubes and from their nozzle openings into the water or other liquid of the bath. These tubes includin g the nozzle openings therefore form parts separate from the grate itself.
All of the known gas-percolating devices of this kind have the disadvantages that they require too many separate parts, that unless special provisions are made it is difficult to keep their nozzle openings in an open position, that their cost of manufacture and thus also their purchase cost is too high, and that their manipulation is often too complicated. These disadvantages are also the reason why such therapeutic devices have so far been limited almost entirely to professional use and why they have hardly ever been sold for use in private homes.
It is an object of the present invention to provide a therapeutic device of the type as described at the beginning which is designed so as to be of a simple and inexpensive construction, to form a single unit when assembled, and to be easily manipulated and very reliable in operation.
According to the present invention this object is attained by providing a grate at least the main upper boards of which con sist of plastic and have a hollow cross-sectional shape so that the insides of these boards form channels for conducting the treatment gas to the nozzle openings, and in providing these boards and in such posithe gas into the bath liquid.
The device according to the invention has therefore the considerable advantage over the gratelike structures as were previously employed for the Same purpose that the different functions of the device, namely, the weight supporting function of the grate, and the functions of conducting the treatment gas to the position of the grate and of passing the gas through nozzle openings in the grate position into the bath liquid are all carried out by a single component, namely, the
is inserted, but while yielding slightly under such a weight, it will have an adequate stability to support this Weight.
According to a preferred embodiment of the invention, the nozzle openings are provided in the lateral walls of the hollow upper boards of the grate which face each other. Thus, no spe- According to another feature of the invention, at least one of the lower cross boards which secure the main upper boards to each other is likewise made of a hollow cross section and its inside communicates by connecting channels with the inside of each of the upper boards. This hollow cross board therefore serves as a conduit for the treatment gas and for distributing the same to the inside of each of the upper boards. These cross boards preferably also consist of plastic which, if necessary, may be reinforced.
For mounting the upper grate boards in the proper position relative to each other and for simplifying the manner of securing them to the cross boards, these cross boards are preferably provided with recesses into each of which one of the upper grate boards is inserted. Thus, the upper grate boards do not merely rest on the upper surfaces of the cross boards but they are also gripped by the lateral walls of these recesses.
In order to insure that the treatment gas will only emerge from the nozzle openings which are provided in the lateral walls of the upper grate boards and may be of any desired number and cross section, suitable sealing means are inserted between the upper grate boards and the lower cross board through which the gas is conducted.
The connecting channels between this gas-conducting cross board and the upper grate boards are preferably provided in the form of bores in resilient plugs each of which has a flange on each end for connecting this cross board to one of the upper grate boards by projecting through their adjacent walls and clamping them to each other while compressing the intermediate sealing means which are mentioned above. These plugs therefore also carry out several functions, namely, to conduct the gas from the hollow cross board to the inside cooperation with the sealing means to prevent the gas from leaking out of the joints between this cross board and the upper boards. The installation of these resilient plugs is very simple because the flange on one end of such a plug is tapered be easily pushed through corresponding bores in the walls of the two boards which are to be connected. Therefore it requires only one simple manipulation to attain all of the results as stated above.
Especially the main upper boards of the grate are preferably reinforced by being provided at the inside of each board with several provided with apertures so as to connect these channels to each other, they may also be solid and only the two outer channels may be in communication by the connecting plugs with the gas-conducting cross board. This latter embodiment effective gas-conducting cross section of the hollow inside of the board is considerably reduced and the treatment gas will FIG. 1 shows, partly broken away, a top view of the grate according to one embodiment of the invention;
FIG. 2 shows an end view of the grate according to FIG. I;
FIG. 3 shows a cross section which is taken along the line III-III of FIG. 1;
FIG. 4 shows a cross section which is taken along the line IV-IV of FIG. 1;
FIG. 5 shows a top view of another embodiment of the invention in which the grate is shown on a smaller scale than that shown in FIG. 1;
FIG. 6 shows a cross VI-VI of FIG. 5; while FIG. 7 shows a cross section of a part of the grate illustrated in FIG. 6.
The therapeutic device according to the first embodiment of the invention as illustrated in FIGS. 1 to 4 comprises a grate which consists of a plurality of parallel longitudinal upper section which is taken along the line boards 1 and of several lower cross boards 2 which secure the adjacent upper boards with intervening gaps to each other. The upper boards 1 consist of plastic and have a hollow crosssectional shape and may be produced, for example, by extrusion. The chamber which is formed in each board 1 is closed toward the outside by cover plates 3 on the opposite ends of the board. These cover plates 3 may be secured to each board by gluing or welding.
The upper boards 1 are secured by screws 4 to the cross boards 2 which may consist of wood or any other suitable material. As shown particularly in FIG. 2, these boards 2 are curved substantially in accordance with the shape of the bottom of the bathtub or the like into which the grate is to be inserted.
This grate is associated with a gas-percolating apparatus of which only the gas distributor 5 is illustrated and which may further comprise a compressor (not shown) from which the gas is conducted through a suitable connecting line to the distributor 5 under an adjustable pressure which may be regulated by suitable control means.
The gas distributor for the grate as illustrated in FIGS. 1 to 4 consists of a pipe 6 which is bent in accordance with the curvature of the cross strips 2 and is provided with a connecting piece 7 for the line leading to the compressor. As shown particularly in FIG. 4, this pipe 6 is connected to the lower side of one end of the upper boards I by short pipe pieces on pipe 6 and by headed sockets 9 which are screwed upon the pipe pieces 10 and are clamped by nuts to the lower walls of the boards I to which they are also sealed by gaskets 11. The axial bores in the sockets 9 and in the associated pipe pieces 10 then form channels 8 which connect the inside of pipe 6 with the insides of the chambers in the upper boards 1.
The gas required for the desired treatment, for example, carbonic acid gas, oxygen, or the like, which is supplied, for example, by a compressor passes through the distributor 5 and the channels 8 into the chambers within the board I. It then penetrates through the nozzles 12, which are preferably provided in the lateral walls of the boards I facing each other, into the bath liquid and produces therein the desired percolating or bubbling effect.
In FIG. 4 it may be seen that the chamber in each board I is reinforced by longitudinal partitions 13 which are provided with the required apertures for the free passage of the treating gas through the chamber and to the nozzle openings 12 in its lateral walls. These reinforcing partitions are adapted to take up and distribute the weight of the body or body parts to be treated which are resting on the grate and they prevent the boards and the chambers therein from being compressed under such a weight.
FIGS. 5 to 7 illustrate another and very preferred embodiment of the invention. The grate again consists of longitudinal hollow upper boards of plastic which are connected to each other by cross boards 21 which in this embodiment likewise consist of plastic. One of these cross boards, the board 22 near one end of the upper boards 20, has a hollow cross section, as shown particularly in FIG. 6, since it serves not only for securing the upper boards 1 to each other but also as a gas conducting and distributing channel so that a separate gas pipe 5 as shown in FIGS. 1, 2 and 4 becomes unnecessary. This hollow cross board 22 is for this purpose provided with a connecting nipple 23 which may be connected, for example, by a hose, to the source of the desired gas under pressure. Cross board 22 is further provided with parallel recesses 24 into which the upper boards 20 are inserted.
For connecting the distributing channel at the inside of cross board 22 with the insides of the upper boards 20, connecting channels 25 are provided which, as shown particularly in FIG. 7, are formed by axial bores in plugs 26. These plugs 26 consist of a suitable resilient material and each of them has a conical flange 27 at one end. These plugs serve for the double purpose of mechanically connecting the cross board 22 to the upper boards 20 and of passing the treatment gas from the distributing channel at the inside of cross board 22 to the channels at the insides of the upper boards 20. When the grate is being assembled, it is merely necessary to insert the upper boards 20 in such positions into the associated recesses 24 in the cross board 22 that each opening 28 in the upper boards 20 is in exact alignment with the corresponding opening 29 in the cross board 22. Before this insertion of the upper boards 20, sealing rings 30 are inserted into the recesses 24 around the openings 29. Thereafter the resilient plugs 26 are pushed from below through the associated openings 28 and 29 until the flanges 27 snap over the lower walls of upper boards 20. The upper boards 20 are thus resiliently clamped together with the cross board 22 and at the same time a gastight con nection is formed between the channels in the cross board 22 and in the upper boards 20. The gas flowing into the channels in the upper boards 20 then passes through the nozzle openings 31 in the lateral walls of these channels into the bath liquid.
As indicated in FIG. 6, the inside of each board 20 is also divided into three longitudinal channels or chambers by being provided with reinforcing partitions 32 which in this embodiment of the invention are preferably solid and not provided with any apertures. The connecting plugs 26 are then inserted into corresponding apertures 28 and 29 in the upper wall of cross board 22 and in the lower wall of the two outer channels 33 so that the gas will only pass through these two channels and then out of the nozzle 31 in the outer wall of each of these channels, while no gas enters the central channel between the channels 33.
