Definitions

  • the invention relates to a portable countercurrent device for swimming pools with a housing in which a driven by a drive motor propeller is arranged, wherein the countercurrent device has a holder for releasable positioning in the pool, wherein the holder has a positionable at the bottom of the pool base-like base, with which the housing is pivotally connected via at least one first retaining strut.
  • Counterflow devices are used for swimming pools to create a steady flow of water in the pool against the direction of swimming of a floating person.
  • the DE 21 25 770 A discloses a portable countercurrent device for swimming pools with a housing in which a drive motor is arranged.
  • the countercurrent device has a holder with a pedestal-like base for detachable positioning in the swimming pool. To ensure a reasonably stable state, the base must have a relatively high weight. Nevertheless, a support on the wall is necessary.
  • the US 5,298,003 A describes a countercurrent system for a swimming pool with a powered by a drive motor under the water surface propeller, which generates a water flow in the water surface area.
  • the drive motor of the transportable countercurrent system is powered by batteries.
  • the countercurrent system is designed to be attached to the edge of the swimming pool. The structure is relatively expensive.
  • the FR 2 886 662 A1 discloses a portable countercurrent system for swimming pools, which is hung on the edge of the pool in the pool and attached via suction cups on the wall of the pool and at the edge outside the swimming pool. Not all swimming pools, especially superficially placed swimming pools are suitable for such positioning of the countercurrent system at the pool edge. In addition, near-surface high-performance countercurrent systems involve the risk that surface air is sucked in, which greatly reduces the generated water flow.
  • a countercurrent system with a support frame known about which the countercurrent system can be supported on the floor and on the wall of the swimming pool.
  • the support frame has adjustable legs for changing the height mounting position of the countercurrent system in the pool.
  • anchors In order to stabilize the frame must be additionally secured by anchors in the area of the edge to the wall of the swimming pool. The disadvantage is that additional, the surface of the swimming pool damaging holes are required. The required fixed anchors also complicate the change in position of the countercurrent system.
  • the object of the invention is to avoid these disadvantages and to provide a portable and easy to install without installation countercurrent device, which can be used in any pool.
  • the base is formed by a bottom plate parallel to the floor, wherein preferably the bottom of the bottom plate is flat and formed with a closed surface.
  • the pedestal base ensures a secure footing.
  • the base plate may be, for example, square, rectangular, triangular, trapezoidal, circular or elliptical. But other geometric floor plans are possible. With a smooth swimming pool floor and a smooth and closed underside of the floor slab, the hydrostatic forces and dead weight are already sufficient with the floor slab resting flat on the swimming pool floor, to ensure a secure footing and to prevent the countercurrent system from tilting, even when the water moves.
  • additional lateral supports may be advantageous.
  • the base on the wall of the swimming pool side facing a support angle normal to the pool floor exhibit.
  • the bottom plate on the side facing away from the flow may have a straight support edge, which rests against the pool wall.
  • a second retaining strut is provided for laterally supporting the first retaining strut or the housing, wherein a first end of the second strut is connected to the housing or to the first retaining strut, preferably articulated.
  • the second retaining strut is detachably, preferably loosely, connectable to the wall of the swimming pool.
  • the device By dividing the forces towards the pool wall and pool floor, the device is fixed during operation.
  • a particularly stable state of the countercurrent system is achieved when the first and second retaining struts span a plane containing the main flow axis at the housing outlet.
  • the second retaining strut is preferably hingedly connected to the base with a second end.
  • a particularly stable construction can be achieved if the first and second support struts form a triangular support together with the pedestal.
  • a tilting of the holder during operation can be reliably avoided if an extension of the main flow axis at the housing outlet cuts the bottom plate in one point.
  • the center of gravity of the countercurrent device is arranged downstream of the surface center of the pedestal, viewed in the flow direction and in the plan view, wherein the housing preferably projects beyond the bottom plate in the flow direction.
  • a safe stand can be further achieved even if the base with at least one suction cup at the bottom of the swimming pool is releasably fastened.
  • the housing is articulated to the first support strut about a pivot axis normal to the axis of rotation of the propeller, wherein preferably an angle between the main flow axis at the housing outlet and the water surface is adjustable which is> 0 °, preferably> 5 °, particularly preferably> 10 °.
  • first and / or second retaining strut is adjustable in length. Furthermore, can be provided be that at least one articulation point of the first and / or second retaining strut on the base or on the housing and / or a point of articulation of the first retaining strut on the second retaining strut is adjustable.
  • a portable countercurrent device 4 is arranged, which in a housing 5 has a drive motor driven by a propeller.
  • the propeller not shown causes an obliquely upward water flow 6, the main flow axis 6a with the water surface 12 forms an angle ⁇ > 0 °, for example 25 °.
  • the countercurrent device 4 can optionally be attached via a suction cup releasably on the pool bottom 3 of the swimming pool 1.
  • Reference numeral 16 denotes a power cable connected to, for example, a rechargeable battery 17. But it is also possible to integrate the battery in the housing 10 of the countercurrent device 3. It would also be possible to operate the device via another low-voltage source.
  • the housing 5 of the countercurrent system 4 can be positioned at any position via a holder 6 in the swimming pool 1.
  • the holder 6 in this case has a base-like base 7, which is formed in the embodiments as a swimming pool floor parallel bottom plate 7a.
  • the base 7 is connected via a first holding strut 8 to the housing 5, wherein the housing 5 is pivotable about a pivot axis 9 normal to the axis of rotation of the propeller. In this way, the countercurrent device 4 can be adjusted to the needs of the floating person.
  • the underside of the bottom plate 7a can be flat and have a closed surface, that is to say be designed without bores or the like. If the bottom plate 7a lies flat on the swimming pool floor 3, only the hydrostatic forces acting on the bottom plate 7a and the dead weight ensure a stable position of the holder 6.
  • a support bracket 10 fixedly connected to the bottom plate 7a may be provided, which is supported on the pool wall 2 ( Fig. 2 ).
  • the bottom plate 7a on the side facing away from the flow may have a straight support edge 10a.
  • a second holding strut 11 connected to the first holding strut 8 or the housing 5 may be used for support on the pool wall 2, as in FIG Fig. 1 is shown.
  • Fig. 3 on the other hand shows a variant in which a first end 11a of the second support strut 11 is connected on the one hand to the first support strut 8, and on the other hand to the bottom plate 7a, wherein first support strut 8, second support strut 11 and bottom plate 7a form a triangle support.
  • the articulation point 8 "of the second holding strut 11 can be designed to be displaceable on the first holding strut 8, for example by a fixable displacing sleeve
  • the articulation points 8 'and 11' of the first and second holding struts 8, 11 on the bottom plate 7a can be adjustable or in addition, the first or second holding strut 8, 11 may be adjustable in length to allow a change in height of the countercurrent device.
  • a stable state in operation is achieved, in particular, when the extension of the main flow axis 6a of the flow 6 at the housing outlet 5a intersects with the bottom plate 7a at a point P, as is apparent Fig. 4 is apparent.
  • the housing 5 can also be arranged to be pivotable on the first retaining strut 8, which allows a particularly compact and stable design.
  • the directed upward to the water surface flow 6 has in addition to the Aufstandstik Aburing effect has the advantage that the countercurrent device 3 on the one hand performed powerful and on the other hand can be positioned deep enough below the water surface 8, without air from the water surface is sucked. As a result, an optimal water flow 6 can be generated.
