Abstract

The solution is a floating floor of the swimming pool of the frame structure, in which the floats are integrated and which is dragged against the lift by the ropes guided over the pulleys fixed at the bottom of the pool. At least four ropes (8) are attached to one end of the structure, and the other end is connected to the central, rope-provided (15) rope (12) exiting the pool by a flooded sachet (13) connected to the pool. The central rope (12) is connected to a linear hydraulic drive (16).

Description

Technical field

Movable floor of a swimming pool of a frame structure in which the floats are integrated and which is dragged to the desired position by a rope guided over pulleys mounted on the bottom of the pool against buoyancy.

BACKGROUND OF THE INVENTION

For outdoor pools, especially smaller private pools, a number of problems need to be addressed, such as covering them, to avoid water cooling at night or freezing in winter and to reduce the risk of drowning children, or to adjust bottom depth according to user needs. There are known swimming pools where the depth can be regulated from the user's point of view by adjusting the bottom height or the bottom height. by adjusting the height of the moving floor above the bottom of the pool. This makes it possible to create a paddling pool, or by raising the floor above the water surface, to create a flat surface for use in various activities. If the floor consists of a structure whose total specific gravity is greater than the specific gravity of water, then the floor is supported by lifting mechanisms, eg rope or hydraulic, that change its position as necessary. Floating type movable floors with a specific gravity of less than the specific gravity of water are known. Then it is necessary to overcome the buoyancy of the submerged floor, either when it is moved or when it ensures its desired stable position.

JP 7166727 discloses a movable pool floor which is pulled to the desired lift position by ropes wound on the drums of a shaft mounted on the bottom of the pool. The shaft passes through the wall of the pool into an underground engine room with a power pack. The disadvantages of this solution are, in particular, the expensive machine room, the waterproof shaft passage through the pool wall and the considerable technological height between the bottom of the pool and the underside of the lowered floor.

In JP 3107070, the draw ropes are guided along the bottom of the pool by pulleys mounted on the bottom of the pool, passing through the wall of the pool at the bottom of the pool and wound on drums mounted on a shaft outside the pool. There is a problem of sealing the passage of the ropes, and winding on the drums does not ensure a perfectly uniform floor movement, which is necessary to translate the floor in the pool.

GB 2167951 describes a frame structure for a floating floor of a swimming pool with fixed modular floor sections made and

- 2 reinforced organic glass with foamed polyurethane core. The position of the float floor is adjusted by a system of ropes and pulleys, possibly fixed by means of pins extending into the sides of the floor. The drive of the cable system is essentially not solved here. The floor construction described cannot provide floor leveling and thermal insulation of the pool water to the surroundings.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a movable floor of a swimming pool with unpretentious control enabling very precise positioning, and its thermal insulating properties are intended to allow the pool to overwinter without draining water.

SUMMARY OF THE INVENTION

This object is achieved by the floating floor of a swimming pool of a frame structure, in which the floats are integrated and which is pulled to the desired position by a rope guided by pulleys mounted on the bottom of the pool against buoyancy. The essence of this floor is that at least four ropes fixed by one end to the structure are connected to the central rope hoist by a flooded shaft connected to the pool, the central rope being connected to a linear hydraulic drive.

In order to facilitate accurate leveling of the floor, the ropes are fastened to the sides of the structure by means of their upper ends and provided with means for adjusting their length in the region of the ends, with covered passages above the means.

In order to ensure that the floor in its upper position at the same time provides good thermal insulation of the pool, its construction is preferably made of a grid welded from closed thin-walled profiles filled with thermal insulation on which the tread plates are glued from above. polystyrene.

To suppress thermal bridges, the profiles are preferably coated with a heat-insulating, non-absorbent layer

For better thermal insulation of the pool, the shaft together with the hydraulic drive is equipped with a thermal insulation cover.

In a preferred embodiment to facilitate transportation, the floor structure is formed by sections bolted in situ.

- 3 Clarifying the figures in the drawing

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic cross-sectional view of a pool provided with a floor according to the invention; FIG. 2 is a plan view of the floor of the pool with the floor circumference indicated; Fig. 5 is a side view and Fig. 5 is a detail of the configuration of the end profile of the structure - section AA of Fig. 4, in a configuration with a pool edge.

Examples of embodiments of the invention

The frame structure of the mobile pool floor consists of a grate 1 welded from closed thin-walled profiles 2 of 100 x 100 mm square cross-section filled with thermal insulation material. In the exemplary embodiment of Figs. 1 and 2, it is comprised of two sections bolted at the installation site. The composition of the floor is evident from Fig. 3. On the profiles 2, the tread plates 4, in the described case made of tempered enamelled glass, are glued over the support strips 3 of PVC. The profiles 2 are covered with a heat-insulating, non-absorbent layer 5 of foamed polyurethane. In the spaces delimited by the wear plates 4 and the profiles 2 are inserted boards 6 of foamed polystyrene serving as floats. Under the edge profiles 2 of the grate on its longer sides are inserted support profiles 7, on which the floor rests on the bottom of the pool and which, in doing so, creates space for the movement device of the floor.

The movement device consists of four stainless steel ropes 8, the upper ends of which are fixed to the side profiles 2 of the grate 1 at points 9. In doing so, they are guided horizontally first and then vertically downwards. In the horizontal section, the ropes are provided with means for adjusting their length, and above these means there are covered passages 10 in the floor structure which allow handling. At the bottom of the pool, the ropes 8 are guided by pulleys 11 into the central part of the bottom, where they are directed by other pulleys 11. With their other end they are connected to the central rope 12.

14. In the shaft 13, the central rope 12 passes through a hoist 15 which functions just in reverse of the conventional hoist, i.e. multiplying the tensile force by the load path. The central rope 12 is then guided through another pulley 11 and connected to i 1 f (

- 4 double acting hydraulic cylinder. The shaft 13 together with this hydraulic drive 16 is provided with a thermal insulation cover 17.

The design includes stabilizers for the upper position of the floor and retaining rope pins that do not drop the floor higher than necessary. The floor has a clearance of 10 mm around the perimeter, which is maintained around the entire perimeter by locking pulleys with elastic pressure. The floor in the composition described has a displacement of 40% by weight. The hydraulic drive 16 pulls the floor against the buoyancy of the floor via the rope system 8, 12 and, on the contrary, releases it upwards when the hydraulic fluid is bypassed. The floor can be stabilized in any position, even at the level of the upper edge of the pool, where, among other things, it serves together with the cover 17 as an effective thermal insulation. All outlet nozzles are located about 150 mm below the surface in the heat protection zone. The height of the skimmer can be adjusted to the desired level, and since it is located in the shaft 13, there is no risk of it freezing. Under the floor in the lower position there is a space of 100 mm, which allows connection of the primary pool heating circuit.
