Open container for stationary swimming

Me innovation concerns an open container to the stationary Swimming with facilities for generating at least a near-surface water flow directed against the swimmer.

Devices for generating a directed flow of water in an open container for swimming without local port movement of the swimmer are of various designs known. The conveyance of a large amount of water by a pump in a circuit through the container and directed Introduction of the water flow through a canal, through one or more nozzle-like pipe connections are just different Embodiments of known devices ,, In these known devices is the shape and size of the container neither according to the requirements of correct flow guiding even after inexpensive manufacture and assembly considered

Me present innovation results accordingly from the task, to remedy the disadvantages mentioned, that is to say, to ape a container for the purpose mentioned, which has the special Flow requirements calculation ti-ägt and which is in Further training taking into account the building requirements in Establish connection with the flow management advantageous leaves.

This task is with an open container of the mentioned Kind of solved, which is characterized according to the innovation in that the space required for stationary swimming In its dimensions adapted container is provided with a head-side niche in which the facilities for generating the circular flow are arranged in such a way that the suction opening is close to the container bottom and that in its direction adjustable, at least one nozzle opening is located in the area of the surface of the water contained in the container.

This solution ensures that there are practically no areas to the side next to the device for generating the flow with backflow and suction effect, or «such areas are reduced to a minimum. Can be beneficial the top view cross-section of the container is kept approximately oval be, whereby additionally the flow-unfavorable areas can be reduced or eliminated. Through the niche training it is also guaranteed that the adjustment of the water takes place in areas that do not affect the near-surface Have swimming and flow areas «- 3 -

Further details are given below on the basis of the graphic Representation of an exemplary embodiment explained in more detail

In terms of length and width, the actual container according to the exemplary embodiment corresponds approximately to the movement space of a swimmer, as well as an additional length in front of the swimmer for the flow of water jets directed towards it. This means about 2 ₉ 3 m width and 3 "5m-length _e The water depth is approximately 1.2m" The basin consists of two Spieg ^ Lbildlich equal executed wall shells 1 with connection slots 4 and a flat bottom tray 2, each circumferential and ~ Have matching screwing flanges 3 By designing the wall shells 1 with an incline inwards, the external width of the floor pan is only about 2 m, so that all arei elements can be transported through a normal door opening To have higher stability and on the other hand to allow both the movements of the swimmer the necessary leeway and also to restrict the water flow behind the swimmer so that it is pushed downwards and flows back to the suction opening 6 as a flow in the opposite direction above the bottom of the container behind the float there are no so-called corner swivels with approximately verti cal axis of rotation generated, which could initiate Gescenströrun ^ eii-iSr-der-swimming plane, which have an unfavorable influence on the main flow effect.

The division of the container into sections of the type mentioned takes into account the arrangement of the aerodynamically favorable niche, due to this division of the relevant container elements can be shaped better *

The suction of the water from the container takes place through a large, rotatably arranged suction opening 6 for the Main flow and through a suction opening 7 through a known filter 8, the suction opening 9 of which is preferably water The water that is sucked in and filtered in this way in the partial flow passes through a suction pipe 5 to. Pump Io and from there via a pressure line 12, partially in the bypass flow via a known Durohflussheizgerät 13, which is controlled by a temperature sensor 14

♦ j becomes manifold 15 · From there it becomes an or several, preferably two, inlet pipes 16 and passed through adjustable jet nozzles 17 at high speed back in the container. The flow cross-section, the position of the nozzle outlets 17 of the vertical and Horizontal transverse to the longitudinal axis of the container, and the direction of the jet nozzles 17 is adjustable. For this purpose, preferably for each inlet pipe 16 two 180 ° bends connected by rotatable screw connections with a front-mounted one known nozzle opening 17 with adjustable passage cross-section and ball joint related.

possibility designed as a rotatably screwed double bend can also be used, for example, on well-known siphon bends uses willows, as they are in plastic as basin drains Find use.

Another embodiment of the inlet pipes 16 consists of an arrangement of a ball joint at both ends, the front one at the same time carrying the adjustable nozzle opening 17.

Suction openings 6 and 7 »filter 8 and inlet pipes 16 with Jet nozzles 17 are in a so-called connection niche. 4-arranged, so that, on the one hand, the suction pipe connection 5 can be made in a favorable manner, so that the protruding part is in the container itself do not protrude in a disruptive manner and the swimmer has no direct contact with the suction opening 6. The preferably Use of two adjustable :; Inlet pipes 16 with jet nozzle 17 allow the swimmer a flow set so that he is in a stable swimming position in a current adapted by direction and strength located Since the entering water jets are converging and directed equally strong on the swimmer, he will if there is a lateral deviation from the central swimming position, it is immediately pushed back again. The collapse especially the Vertical after means the advantageous possibility of moving the incoming Y / water streams according to the capabilities of the To adjust the float. This is how an underwater

mirror almost horizontal currents stronger and with lively wave formation, while an oblique upward current that begins at a greater depth gives the swimmer more buoyancy and creates fewer waves in front of the swimmer's head Adjustability of the inlet tubes 16 and jet nozzles 17 therefore facilitated because of the shoulders to the leg muscles all games can be achieved _e the divisibility of the container also permits the easy assembly and manufacture of the intermediate floor as it is placed in phantom in FIG · 1, by which a very clear flow separation is created in the nozzle and suction area
