DESCRIPTION OF THE PREFERRED EMBODIMENTS As can best be seen in FIG. 1 at the bottom of a bathing-tub a grate-like mat or lattice like assembly of tubes 2 is put consisting of lath planks or plastic profiles 3 and

tubes

4, 5, 6' and 7. Small bores or holes are made into the side walls of the tubes 4 to 7. The

tubes

4, 5

and 6 are placed side by side, in parallel, while the tube of a bathing tub. The bellows may be worked alternately.

Alternatively, the pump of a vacuum cleaner may be used by connecting the pressure side thereof with the assembly of tubes.

In order to mount the two bellows within the bathing tub, it is preferred to use suction cups. A rod-like support can also be used, the ends of which are provided with suction cup-like restsand whose effective length is changeable by screws. In this way it is possible to mount the device of the present invention to ordinary bathing-tubs without requiring special works to accomodate it. The screws consist of a turning handle with rightand left-handed thread. A second rod vertical to the first rod can be arranged to be supported on the foot-end of the bathing-tub.

The tube assembly may comprise a special tube for connecting the pressure-reservoir which can be an oxygen cylinder or a boiling-water preparing device. When the pressure reservoir is a device for boiling water, a type is used in which bathingor medical additive can be supplied and which has a waste steam pipe so that the developed steam as well as the additive can be directed into the special tube. Furthermore, the device for boiling water is controlled by the temperature of the steam in the special tube in order to preclude on scaldand 18 each are respectively connected with the ings when maintaining a desired constant temperature.

The device comprises a covering adapted to the bathing-tub and letting free the head of a person using the device, while preparing a Roman bath or a steamor vapour-bath.

These objects and other features of the present invention will become more apparent from the following illustrative description taken in conjunction with the accompanying drawing.

7 serves for connecting the

other tubes

4, 5 and 6.

Flexible pipes

10, 11 and 12 are connected to the ends of the

tubes

4, 5 and 6. The pipe 10 leads to a bellow 15 and the pipe 12 to a bellows 16.

The

belows

15, 16 as can best be seen in FIG. 2 are arranged inside of the bathing-tub and mounted on a wall thereof by means of suction. cups (not shown). Such suction cups are well known. The suction cups have a side fixed onto the respective bellow and a suction side for mounting and demounting the bellows. In FIG. 1 the

bellows

15, 16 have been shown outside of the tub only for sake of clearness of the drawing. The

bellows

15, 16 have inlet-

pipes

17 and 18 respectively which may be connected to one pipe 19. The pipes 17 interior of the bellows 15-16 by inlet-

valves

21 and 22, respectively, while the outlet-

pipes

10 and 12 each have outlet valves 23 and 24 respectively. The valves 21 to 24 are simple checkvalves.

StilI referring to FIG. I, the rrii ddle tube 5 is connected by pipe 11 with a steam-preparing device 30 and can be separated from pipe 11 by a valve (not shown). The pipe 11 may comprise a cooling water jacket for cooling the steam. As a steam-preparing device, an apparatus is used having a filling hole for bathing or medical materials, that is closed by a cap 31 absorbing a certain pressure. For controlling the streampreparing device, a control system 32 is used having a temperature sensing device 33 arranged at the middle tube 5 such as to switch on or off the power supply to the stream-preparing device 30 according to the requirements. The control system 32 may include a thermostat so that the steam temperature in the tubes 4-7 be chosen. Furthermore, the tube 5 may comprise an electro-magnetic stop valve (not shown) operated by the control system 32.

Together with the steam-preparing device a covering (not shown) of the bathing-tub can be used which is adapted to fit around the neck of the bathing person.

In FIG. 2 a method of fastening of the

bellows

15 and 16 directly at the foobend of the lbathing-tub is shown. The fastening consists mainly of a rod 40 as well as of another rod (not shown) arranged vertically to the first one extending against the end of the bathing-tub 1 to prevent the rod 40 from tilting. The rod 40 itself consists of two

tubes

41 and 42 at the ends of which

suction cups

43 and 44 are attached flexibly, for example by ball joints. The tube 41 has a right-handed thread while the other tube 42 has a left-handed thread. A turning handle 45 with

screws

46 and 47 has been screwed into the ends of the

tubes

41 and 42 so that by turning the handle 45 the effective length of the rod 40 is changeable. The rod 40 can therefore be squeezed in between the two side walls of a bathing-tub whereby the

suction cups

43, 44 straighten according to the inclination of the sides of the tub 1. The two

bellows

15 and 16 are fixed to the rod 40 by

butt straps

48 and 49, and the back of the

bellows

15 and 16 lay against the d. 01th? b thingi b The pipe 11 can also be connected with an oxygen cylinder, if it is desired to distributed oxygen instead of air.

FIG. 3 shows another variation for the fastening of the

bellows

15, 16. A bed-like supporting construction 50 is provided which consists of a section 51 running horizontally and following the bottom of the bathingtub and a section 52 rising up the head end wall of the bathing-tub The two

sections

51, 52 are connected flexibly one to another. Each section may contain two rails, for instance two U-rails 53 or 54, connecting

plates

57, 58 as well as pads of

plastic foam

55, 56. The

bellows

15, 16 lie over part 52 while the lattice like assembly is put onto the part 51.

FIGS. 4 and show a further, preferred embodiment of the invention. Like parts to the first described embodiments have reference numbers increased by 100.

Plastic profiles 102 are arranged parallel to one another and vertically to plastic profiles 103 that are parallel to one another, too. The

profiles

102 and 103 are fixed together by glueing orwelding to form a grate like mat or a bed like construction having two

sections

151 and 152 that are connected pivotally one to another. The profiles 103 have ribs 103a and notches made therein. The notches 103b consist of slits and cylindrical extensions to accommodate flexible plastic tubes 104a, b and 106a, b having fine bores for passing through the substances to be distributed. The tubes 104a, b and 106a, b are connected together by pipe joints 108 having three arms to form a lattice like assembly.

Pipes

110 and 112 are connected with free arms of joints 108 and lead to a valve block 120 having

inlet openings

117, 118,

inlet valves

121, 122 and

outlet valves

123, 124. The valves 121 through 124 each comprise a valve body 125 cooperating with a respective seat 126 formed on the valve block 120 that includes two chambers 127 (one of which is shown in FIG. 5). The back walls of these chambers 127 are made of a common flexible plate 128, while the front walls 129 are formed with flanges to hold

bellows

115, 116. Helical springs 119 in truncated cone forms urge the rims of the

bellows

115, 116 against the flanges 129 to form an air tight seat and to restore the initial shape of the

bellows

115, 116. As may be seen by those skilled in the art, bellows 115, 116 and valve block 120 together with valves 121 124 form a pump device feeding air when the bellows are actuated alternately. The back wall 128 carries two

suction cups

143, 144, one side of which is permanently fixed to the valve block 120 while the other side serves to detachably mount the valve block 120 and the

bellows

115, 116 onto a bathing tub. In order to accommodate the bellows to a curved wall of a bathing tub, the plate 128 may bent.

When disengaging

pipes

110, 112 from the valve block and using a pipe joint similar to pipe. joint 108, that fitting is ready to be connected to a source of air (vacuum cleaner) or of oxygen (oxygen cylinder) or of steam (steam preparing device), thus providing a device for distributing air, oxygen, steam and bathing or medical additives in bathing water of a bathing tub.
