The Fig. 1 shows a schematic plan view of a swimming pool 2 with a cover 1, which is composed of a plurality of mutually parallel blade leaves 3, wherein the blade leaves 3 are only partially shown. In a non-rectilinear pool edge 4 ', the lamellar blades 3 necessarily have different lengths, so that the pool cover 1 as a whole almost completely covers the water surface of the swimming pool 2. The cover 1 is on a submerged roll-up mechanism 5, which will not be described here, after a predetermined program 5 'up and unrolled, the lamellae 3 of the cover 1 are led out of the water in a guide rail.

FIG. 2 shows a swimming pool 2 in cross-section on the water surface 6 which is composed of individual lamellar leaves 3 swimming pool cover 1 floating. In the present embodiment, the inner walls 8 of the swimming pool 2 are provided at the upper edge with a slight slope 7, the water surface 6 with the upper edge of the pool walls 8 closes. In such embodiments of the inner walls with an upper bevelled edge portion 7, it is appropriate to the lateral end caps 9, a non-rigid guide member 10, which will be described in more detail below, to arrange, which serves to ensure that the front lamellae 3 of the cover 1 is not on the Pool edge 4 are pushed out. For a swimming pool 2, the only pool walls 8 with straight walls, so no slope 7, have, provides a projection 11 at the end cap 9, which will be described in more detail below, the guide element.

The FIG. 3 shows a schematic plan view of a single fin blade 3, the two ends are each sealed with an end cap 9. The end cap 9 is formed so that they protrude into the cavities 12 of the fin blade 3, wherein the cavities 12 are formed as a result of elongated webs 15. The cavities 12 are fixed in the end region of the end cap 9 with a special fastening means on the inner walls of the cavities 12 in the slats 3.

Due to the relatively small specific weight of the lamellae 3, which are usually made of a suitable plastic, the lamellae 3 dive only slightly into the water of the pool 2, whereby the movement of the cover on the water surface 6 is given only a small resistance , The individual lamellae 3 consist essentially of a hollow profile having at least two cavities 12, which are formed as a result of elongated webs 15. The lamellar blades 3 have on a longitudinal side hook-like rails 13 which are inserted in a certain manner in a counter-profile 14, whereby an articulated connection between the individual lamellar leaves 3 is formed. As a result of the articulated connection between the individual lamella leaves 3,3 'is formed transversely to the longitudinal axis of the slats a relatively flexible cover 1, which can be on a winding device 5, not shown on a drum and unrolled.

The FIG. 4 shows the cross section of a single fin blade 3, wherein each individual blade leaf 3 from a hollow profile, which has at least one hollow chamber 12, wherein the individual hollow chambers 12 are formed by longitudinally extending spacer webs 15. The lamellar blades 3 are made to a length corresponding to the swimming pool contour, so that the ends of the lamella blades 3 are initially open.

FIG. 5 shows a schematic side view of an end cap 9, the stamp-like thickening 16, 16 'are inserted into the hollow chambers 12 of the individual lamellar sheets 3 to complete the cavities of the lamellar sheets 3 and make them waterproof. The end caps 9 can be used in certain cases as a guide element on the walls 8 of the swimming pool 2, provided that the walls extend vertically. The end cap 9 has on the outwardly facing end face on a projection 11 which extends almost at right angles from the end face 19 of the end cap 9 and may be formed circular segment-shaped. The outwardly facing circular segment-shaped rounding of the projection 11 serves to ensure that no contact occurs in contact with the inner wall 8 of the swimming pool 2, which could hinder the locomotion of the cover 1.

The end cap 9 has comb-like punch-shaped struts 17, which extend into the interior of the lamella chambers 12, as already indicated above. The struts 17 each have at the top and bottom a diameter equal thickening 16,16 ', whose diameter is slightly smaller than the inside diameter of the cavity 12. The thickenings 16, 16' are each connected by a strut 17, the length thereof it is to be selected that there is sufficient clearance in which the bonding agent (silicone) can spread to produce a durable watertight connection to the openings of the lamella blades 3.

The FIG. 6 shows a schematic side view of the tilted by 90 ° end cap 9 FIG. 5 , the end face 19 of the end cap 9 is largely adapted to the outer cross section of the lamellae, so that in this illustration upwardly facing side 18 of the end cap 9, which lies on the water surface, in the present embodiment is rectilinear and the side opposite this side 18 'light formed curved and is substantially adapted to the cross section of the blade plate 3. The end face 19 of the end cap 9 has at least two bores 20, 20 'above the projection 11, with a bore 20 serving to convey the binder (silicon) into the hollow chambers Insert 12 and the other bore 20 'serves to inflate the displaced air from the hollow chambers 12. In the openings of the hollow chambers 12, an end cap 9 is used on each side of the blade 3, which is fixed with a predetermined, color-matched special fastening means in the end region of the individual blades 3. The fastening means extends over the entire internal volume formed between the thickenings 16, 16 'of the punches 17 formed by the insertion of the end cap 9 and thus provides an adhesive connection between parts of the inner fin wall and the end cap 9. The special fastening means is prefabricated in a specific color, wherein the coloration is adjusted so that the overall impression of the coloration in plan view of the finished end portion of the individual slats 3 with inserted end cap 9 due to the interference of different color components of the assembled components in the end of the slats 3 no Color difference between the end and the remaining color of each slat 3 can be seen. In other words, that the coloring of the end portion of the slats 3 with inserted end cap 9 due to the interaction of the individual color components, or the interference of the Wavelengths of the individual colors, both the inserted end cap 9 and by the color of the fastener and the color of the material of the original fin blade 3 is formed.

The FIG. 7 shows a schematic perspective view of a sealed with an end cap 9 fin blade 3. On the outside of the end cap 9, a guide steering member 10 is pivotally arranged in the present embodiment with a screw 21 that forms at certain beveled edges 4 of the swimming pool a guide that prevents in that the pool cover 1 extends beyond the edge of the swimming pool 2. The front side 19 is formed so that it just covers the groove 14 of the outer cross-sectional profile of the slats 3. On the side of the end cap 9, which faces the elongated groove 14 of the lamellae 3, covers the end face 19 of the end cap 9, so also the opening of the groove 14. This ensures that an inserted into the groove 14 spacer element 22 is not out of Groove 14 slips and thus provides the shorter preceding blade a fixed position. Such spacers 22 are used for pool covers with contoured pool edges 4 'to provide a pool cover for uneven pool surfaces by simple means. This protrusion over the groove 14 serves that at different lengths of the slats 3, a spacer 22 can be inserted in order to prevent the inserted slat 3 shifts in their once specified position. The length of the spacer element 22 depends on the contour of the edge 4, 4 'of the swimming pool 2. Thus, 22 differently shaped contours of the swimming pool cover 1 are obtained by inserting different lengths of the fins 3 and inserting the corresponding spacer elements Contours of the water surface of the swimming pool 2 correspond.

The FIG. 8 shows the side view of two assembled lamellae 3,3 ', the average imaginary virtual planes are inclined at an angle α to each other. This inclination by the angle α is particularly important for the trouble-free rolling on a winding roll (not shown here) wound pool cover 1 to specify when unwinding the cover 1 on the water surface of the pool a direction to hang on the water surface. The predetermined inclination with the angle α is achieved in the present embodiment with a flat sheet that has two legs 24,24 'whose longitudinal axes are inclined by the angle α against each other. Each of these legs 24,24 'has at least one bore, each receiving a screw 23 and which secures the flat sheet on the end face 19 of the end cap 9. The angle α is substantially an obtuse angle and is depending on the embodiment of the pool cover between 110 ° and 180 °.

The FIG. 9 shows a perspective view of two assembled lamellae 3,3 ', the angle of inclination is achieved with a clamping plate 25 as a fixing element which is arranged in the present embodiment on the undersides of the two candidate lamellae 3,3'. Approximately in the middle of the clamping plate 25, in the region of the bend in the clamping plate is an elongated, downwardly facing guide-steering element 26 arranged that is elastic in the present embodiment, ie that the longitudinal axis of this guide-steering element 26 is not rigid, but flexible elastic is what is achieved here with a spiral spring. In a further embodiment, the guide-steering element 26 could also be made of an inherently elastic plastic. It is important that the Guide-steering element 26 is fixedly secured with its one end to the clamping plate 25. The ends of the legs of the clamping plate 25 have on one side a U-shaped clamp bracket 27, and at the end of the other leg of the clamping plate 25 is formed a step-shaped rebate edge 28, the clamping releasably connected to the hook-like cross-section rail 13 in connection stands. Due to the inclination to the predetermined angle α between the two legs of the clamping plate 25 and the clamping effect of the clamping plate 25 to the blades 3, 3 ', the two blades take about the same inclination, which specifies the clamping plate 25.

The FIG. 10 shows, similar to the FIG. 9 in a perspective view of the underside of a lamella blade 3, on which a clamping plate 25 'is in clamping engagement with the edges 13, 14 of a blade leaf 3 in operative connection. Such a clamping plate 25 'can be arranged at a freely selectable location of a pool cover 1 as a guide element when the boundary conditions of the swimming pool 2 make it necessary.

The FIG. 11 shows a further variant of a clamping plate 25 ", that in contrast to the clamping plate 25 off FIG. 9 on the one hand has no guide element and on the other hand about the middle of the end of the one leg a U-shaped fold 27 'is arranged, which is the step-shaped Abjungung 28 directly opposite, whereby in the clamped state, the stability of the inclination of the fin blade 3' is significantly improved.

The FIG. 12 shows a side view of an end cap 9 at the end of a fin blade 3 on the end face 19 of the end cap 9, wherein a multi-member guide-steering element 10 'is pivotally mounted. The guide-steering element 10 'has approximately in the middle a hinge 29, whereby the possible use of the guide member 10 'is increased at differently shaped pool edges 4,7.

The FIG. 13 shows a schematic cross-sectional view of a swimming pool 2 on the water surface 6 a plurality of interlocked lamella leaves 3 are floating. The upper edge of the pool wall 8 'terminates with a slope 7', whereby the reflection of waves and thus a significant part of the wave formation in a swimming pool 2 is at least attenuated. Due to the slope 7 'of the edge of the swimming pool 2, it is virtually impossible to obtain a defined stop for a guide element or the side of a lamella blade 3. In order to eliminate this circumstance, at the first louver 3 or the second louver 3 'of the entire pool cover 1 is a guide-steering element 26, as in FIG. 10 is shown, arranged at a predetermined location of the end cap 9 of a blade leaf 3. The length of the guide member 26 depends on the slope 7 ', ie, how far the end of the slope lies below the water surface. The arrow A above the lamellar blades 3 points to the two directions of movement of the pool cover 1.

In summary, it may be stated that with the present invention, a system for a pool cover 1 is presented, which on the one hand also suitable for non-linear shapes of the pool border 4 and on the other hand increases the reliability of the pool cover 1, which for example by a number of aids such as clamping plates 24th , 25 and guide-steering elements 10,10 ', 11,26 is achieved. Further, in the open ends of a hollow blade 3 for sealing the inner chambers 12 of the hollow blade 3 and for guiding the blade 3 on the pool walls. 8 an end cap 9 introduced into the cavities 12 of the open fin ends, the shape of which serves, inter alia, the leadership and the surface design of the pool cover 1. The end cap 9 according to the invention is fastened to the inner walls of the hollow lamellar blade 3 with a special predetermined fastening means. As a result of the interaction of different wavelengths of different color components of the individual components between the hollow blade 3, the end cap 9 and the fastener, a resulting color is formed, which corresponds at least similar to the color of the entire blade plate 3.
