EQUIPMENT FDR PRODUCING BUBBLE BATHS Filed Nov. 28, 1958 FIG.
FIG. 4
5 2a c 2 a INVENTOR. EMMH LEF W mama S. sflMe Z Mam/aw United States Patent 2397.285 EQUIPMENT FOR PRODUCING BUBBLE BATHS Emma Lefmann, An den Kellern 33, Erlangen, Germany Filed Nov. 28, 1958, Ser. No. 776,809 Claims priority, application Germany Sept. 17, 1958 '1 Claim. (Cl. 261-124) ment which may be placed in a bath tub or the like for producing the bubble bath.
To this end, the invention provides a bubble-producing mat which may be placed upon the bottom of the tub and upon which the user or patient may recline, and from which the bubbles may rise as from a multitude of jet orifices or other gas release passage means producing the desired bubble efiect in the bath.
The mat comprising a plurality of spaced parallel flexible air distributing conduits for releasing air or another gas into the bath is so constructed that it may be compactly rolled up and conveniently stored. Preferably, these conduits extend transversely of the mat in alternation with panels also extending transversely of the mat.
More particularly, the invention provides a bubbleproducing mat featuring an arrangement in which a plurality of transverse panel units consisting of a synthetic material capable of adapting itself to the bottom of the tub, are arranged edgewise side by. side in sequence although slightly spaced from one another. Combined with these panel units are gas supplying hose means adapted to release bubbles from orifices or the like, extending in and along the spaces between respective panel units so that the panel units alternate with interposed portions of the gas releasing hose located between respective edges of adjoining panel units. For example, flexible connecting means of a suitable tough synthetic material may be so arranged that they will interconnect the hose portions and the panels so as to constitute the bubble producing mat.
Preferably, a single length of perforated gas supplying hose is arranged along a meandering line engaged by the panel units.
Features lie in the provision of flexible linear connecting means or bands arranged to serve the dual purpose of tying the panel units as well as the interposed hose portions to one another to constitute the bubble producing mat, with the interposed base portion in effect serving as hinging means for the respective panel units when the mat is to be rolled up and stored.
Other features lie in the particular shape and construction of the panel units.
The novel features which are considered as characteristic for the invention are set forth in particular in the appended claim. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be best understood from the following description of specific embodiments when read in connection with the accompanying drawing in which:
FIG. 1 is a plan view of the bubble producing mat in a preferred embodiment of this invention, showing the elongated panel units assembled and interconnected with the gas supplying hose means.
G. 2 is an enlarged end view of a single panel unit taken on line 22 in FIG. 1.
FIG. 3 is a side edge view of the panel unit taken on line 3-3 of the panel unit shown in FIG. 2.
FIG. 4 is a fragmentary cross-sectional view taken on line 4-4 in FIG. 1, showing more clearly the linear connecting means whereby the panel units and the gas supplying hose are interconnected.
Referring to the drawings, the bubble producing mat according to an embodiment exemplary of the invention, comprises a plurality or sequence of elongate panel units or panels 1 arranged in a common plane edgewise side by side and somewhat spaced from one another in such a manner as to accommodate a single flexible gas supplyinghose 2 in the spaces between the row of coplanar panel units.
There are shown in this example a convenient number of six such panel units 1, the shape of each of which in plan view is defined by a pair of parallel longitudinal sides 1a and semi-circular rounded ends 1b. A length of gas supplying hose 2 in the example of FIG. 1 is shown to be of a continuous length extending in a meandering path and in the plane of the panels whereby it provides straight hose portions 2a interposed between the longitudinal edges of respective adjoining panel units, and curved or rounded portions 2b, engaging and hugging respective rounded ends 1b of the panel units.
The gas supplying hose in this arrangement has along the length thereof gas passage release means or gas discharging openings -for emitting into the bath any suitable gas for therapeutic treatment, for example, air, carbon dioxide or oxygen, this being indicated by openings 20 spaced along the effective length of this hose.
As may be seen from FIGS. 2 and 4, the panel units have parallel longitudinal hollow spaces 10, as well as apertures 1:1 in the edge portions and in the wall portions that separate the hollow spaces or liquid receiving chambers from one another. In this way each panel unit is provided with a pair of parallel transversely extending passages across the longitudinal spaces, for the purpose of receiving linear connecting elements or bands which may be of a tough flexible synthetic material whereby the panel units as well as the interposed gas supplying hose portions may be interconnected. Accordingly (see FIGS. 1 and 4) a pair of linear flexible connecting elements or hands B and B of such material, extend through these transverse passages, parallel to one another and from end to end of the bubble producing mat, the ends of the bands B and B being fastened to or anchored in a pair of respective terminal panel units T and T respectively. As shown, each of these terminal panel units may constitute one-half of a panel unit 1.
As shown in FIG. 4, the linear flexible connecting element B has straight portions b extending through respective panel units, alternating with loop shaped portions b through which in turn pass respective hose portions 2a. The construction and mounting of the other linear flexible connecting element B is the same.
The perforated gas supplying hose 2 as herein illustrated has a perforated entrance end portion E located between the terminal half panel unit T and the adjacent full-sized panel unit 1, and it has a perforated terminal portion E located between the terminal half-panel unit T and the adjacent full-sized panel unit 1. The entrance end portion E of the gas supplying hose has an extension S terminating in a suitable fitting or connector 3 by means of which it may be connected to a suitable source of therapeutic gas under pressure. By means of this terminal fitting 3, the hose extension S may also be connected to a source of compressed air conveniently available for instance from a home vacuum cleaner or the like when the same is operated for blowing instead of for suction, whereby the need for an expensive compressor unit or bottled compressed air is obviated.
With respect to the panel units 1, it should be noted that in a preferred form they consist of a synthetic ma- Patented Aug. 22, 19 1 terial which at the temperature of the bath may become readily deformed in such a manner that it will mold or adjust itself to the contour of the bottom of the bath or tub, but-will resume its normal shape when removed from the bath. The panel units constructed in accordance with the invention are prevented from floating by water filling the hollow longitudinal spaces or chambers in the panel so that the row of interconnected panels is submerged in a body of liquid when the mat is placed into a bath tub or like receptacle.
In distinction from wood as a material for the mat, which may become slippery or slimy, and also in distinction from parts made of steel tending to corrode or rust and to deteriorate, the synthetic material from which the panel units are made according to this invention is unobjectionable hygienically and "otherwise, and it may be readily cleaned in a convenient and expeditious manner.
When so constructed in accordance with this invention the bubble producing mat has a durability which is practically unlimited, and since it may be rolled up into a compact bundle, its storage requirements are minimized.
It will be understood that each of the elements described above, or two or more together, may also find a useful application in other types of bubble producing mats difiering from the type described above.
While the invention has been illustrated and described as embodied in a bubble producing mat composed of panel units and gas hoseportions arranged in' alternation and extending transversely of the mat, it is not intended to be limited to the details shown, since'various modifications and structural changes may be made without departing in any way from the spirit of the present invention.
Without further analysis, the foregoing will so fully" reveal the gist of the present invention that others can by applying current knowledge readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention and, therefore, such adaptations should and are intended to be comprehended within the meaning and range of equivalence of the following claim. What is claimed as new and desired to be secured by Letters Patent is:
A bubble producing mat insertable into a body of liquid for providing a bubble bath for therapeutic and like purposes, said mat comprising, in combination, a plurality of elongated coplanar panels consisting of an elastic material, said panels arranged side by side in a row, slightly spaced from each other, and formed with aligned transversely extending passages extending between opposite edges thereof; a single gas supplying flexible hose of elastic material extending in a meandering path between and in the plane of the spaced panels so that the panels alternate with interposed portions of said hose, said hose formed with a plurality of gas discharging openings; and flexible connecting means extending through said transversely extending passages and secured to each of said interposed hose portions so that said hose portions and said panels are connected to each other and'that said row of panels may be folded along each interposed hose portion.
