Detailed Description of the Invention According to fig. 1 , an underwater-above water accommodation comprises an underwater accommodation 1 , which is submerged under the water surface, and above water accommodation 2, located above the water surface. The above water accommodation 2 can be lowered onto the water surface. Both the underwater accommodation 1 and the above water accommodation 2 are slidably joined to three vertical legs 3,4,5, which pass through the structures of the underwater accommodation 1 and above water accommodation 2 and which are provided, at their lower ends, with feet 6,7,8, resting on the bottom of the water region in the place of use of the object.

At the sliding joint with vertical legs 3,4,5, the underwater accommodation 1 has sliding joint bushings 9,10,1 1 , tightly connected to the pressure shell 12 of the underwater accommodation 1 , whereas at the sliding joint with vertical legs 3,4,5, the structure 13 of the above water accommodation 2 is fixed to the sliding joint bushings 14,15,16.

At the top of the underwater accommodation 1 , fixed to the shell 12 is a vertical shaft 23, slidably mounted in a sleeve 24 which is fixed to the structure 13 of the above water accommodation 2. The vertical shaft 23 is provided with a platform 25 at its upper part, a lift 26 mounted within guides 27 and stairs 28.

In the lower part of the shell 12 of the underwater accommodation 1 , there is located a ballast tank 29 filled with water whereas in the lower part of the above water accommodation 2 there is another ballast tank 30 filled with water and fixed to the structure 13.

In the first embodiment of the structure of the assembly for moving the legs 3,4,5 with respect to the structure 13 of the above water accommodation 2 according to Figure 3, to each vertical leg 3,4,5 there is secured a rack 31 cooperating with a toothed wheel 32 driven by a drive unit 33 and attached to the structure 13 of the above water accommodation 2; the drive units 33 raise and lower the above water accommodation 2 on the legs 3,4,5 by operation of the toothed wheels 32 engaged with the racks 31 attached to each of the vertical legs 3,4,5.

In the first embodiment of the structure according to Figure 6, a drive wheel 49 is attached to the structure 13 of the above water accommodation 2 and is connected to a brake drum 50 and driven by a drive unit 52 via a disengaging clutch 51 and there is a chain or a rope 44 wound on the drive wheel 49. The brake drum 50 is in contact with a brake pad 54, which is pressed against the brake drum 50 by a brake pad actuator 56 with the use of an actuator lever 55.

In case of emergency, the underwater accommodation 1 is automatic surfaced after the pressure of the brake pad 54 on the brake drum 50 is released and the jaws of a locking device 46 opened.

In the second embodiment shown in Figure 2, the sliding joint bushings 17,18,19, in which the legs 3,4,5 are located, are attached to the pressure shell 12 of the underwater accommodation 1 on the outside of this shell 12, whereas at the sliding joint of the above water accommodation 2 with vertical legs 3,4,5, the structure 13 of the above water accommodation 2 is fixed to the sliding joint bushings 20,21 ,22.

According to Figure 4, in the second embodiment of the assembly for moving the legs 3,4,5 with respect to the structure 13 of the above water accommodation 2, each vertical leg 3,4,5 is provided with one vertical row of holes 34, which holes 34 alternately receive pins 35 and 36, mounted slidably in guiding elements 37 and 38 where one kind of the guiding element 37 is movable by a guiding element actuator 39 and together with the guiding element actuator 39, is fixed to the structure 13 of the above water accommodation 2, whereas another kind of the guiding element 38 is movable by a guiding element actuator 40 and, together with the pin 36 and the guiding element actuator 40, is fixed to the base 41 vertically slidable by means of a base actuator 42.

Synchronized, alternating movement of the pins 35 and 36 and the guiding elements 37 and 38 slides the leg 5 with respect to the structure 13 of the above water accommodation 2.

In the position shown in the second embodiment of Figure 4 the weight of the above water accommodation 2 is transmitted by the pin 35 inserted into one of the holes 34.

In Figure 5 the weight of the above water accommodation 2 is transmitted by the pin 36 inserted into the one of the holes 34 and the movement of the pin 36 enforced by the base actuator 42, triggers the movement of the leg 5 with respect to the structure 13 of the above water accommodation 2, and when the leg 5 reaches the proper position in respect of the structure 13 of the above water accommodation 2 the pin 35 is inserted into another hole 34 and the weight of the above water accommodation 2 is transmitted by this pin 35.

To the lower part of the shell 12 of the underwater accommodation 1 , there is attached, at each vertical leg 3,4,5 at a certain point 43, a chain or a rope 44 that passes through a roller 45 and the locking device 46 having the jaws clamped with a jaw actuator 47 and a screw 48 with a hand drive. With the use of the chain or the rope 44, the underwater accommodation 1 moves vertically, submerging under the water surface or emerges above the water surface during the normal operation of the underwater-above water accommodation.

In the second embodiment according to Figure 7, , the chain or the rope 44, passing through the roller 45 and the locking device 46, is attached to a hydraulic actuator 57 powered by a pipe 58 in which a cut off valve 53 is installed.

In case of emergency, the underwater accommodation 1 is automatic surfaced after the cut off valve 53 and the jaws of the locking device 46 have been opened.

Method of Industrial Application of the Invention

The underwater-above water accommodation according to the invention is placed on the bottom of the water region. It can be used for rest and recreation purposes in the aquatic environment where the people staying in the underwater accommodation or the above water accommodation can observe this environment. The described above construction of the accommodation ensures safety for the people staying in the underwater accommodation due to its capability of rapid surfacing.
