DE2354279A1 - Swimming pool cover with inflatable cushion - attached at one edge to roller at side of pool and at other to inflating connection - Google Patents

Abstract

Swimming pool cover to reduce evaporation consists of an inflatable cushion with one edge attached to a roller swivel mounted along one longitudinal edge of the pool. The cushion is formed by two individual chambers connected by a chamber with inlet and outlet valves and by intermediate covering surfaces. The inflating connection and the connection chamber are at the end of the cushion not attached to the roller and the inflating connection has a pressure inlet mechanism. The roller has a roll-in drive or a driveless counter pressure roller.

Description

The invention "relates to a swimming pool cover, consisting of from one covering at least the basin opening and if necessary γοη the pelvic opening removable skin "

Swimming pool covers of the type mentioned are already available known. Such covers, for example according to US Pat. No. 3,427 are used in order to reduce the pollution of the water surface in the times of peak use.

In the case of beekeys housed in halls, the removal of air humidity due to evaporation on the surface of the swimming pool water is problematic. The air humidity in a swimming pool increases significantly at times when many people swim and move the water strongly. So far it has been customary to switch the air over exhaust air to the undesired. , «/ 2

to dissipate humidity. This can be done as long as the outside temperature is not very high and the humidity is not very high the outside air is relatively low «,

The difference between the humidity of the outside air and the indoor pool air must be significant. Works outdoors in summer with air temperatures above 20 ° C the removal of the humidity is no longer good » The removal of humidity via fresh air, which has to be heated, means a considerable amount of energy and costs ο

With the previously known swimming pool cover mentioned above, the problem could be solved, but it is awkward to use and may still be acceptable for small pools despite cumbersome handling, but this solution cannot be used for larger pools

The invention is accordingly based on the object of eliminating these disadvantages, d.lu, a swimming pool cover, in particular for indoor swimming pools are created that are easily accessible the water surface when the pool is not in use to reduce water evaporation and which can be removed just as easily and quickly.

This task is with a swimming pool cover according to the

that the skin is designed as an inflatable pillow, the one with an edge on one along a swimming pool rim— attached to the rotatable roller and the inflation port is arranged at the roll-free end of the cushion.

With this solution there is no need for brackets or guides, because the cushion is self-guided at the edge of the pool when it is inflated, whereby a dimensioning of the cushion corresponding to the water surface is not necessary is. By arranging the cushion on a roller that takes the cushion when it is not inflated, the cushion rolls automatically when it is inflated off the roll and slides over the entire surface of the water, and only for removing the cover a roll-in drive is required on the roll, which clay can also be done by hand «,

To when rolling up, before opening the pillow beforehand is to remove all air, the role can advantageously be assigned a size pressure roller, through which the Air is printed in the part of the cushion that has not yet been rolled up ο

For its intended purpose, it is not essential that the entire pillow be inflatable, but rather it is is sufficient if the pillow extends in the pull-out direction Individual chambers, which are separated

deck surfaces are connected. / »

These are preferably single chambers in the inflated State to a certain extent form a supporting skeleton for the entire cover, with a connecting chamber at the roller-free end provided, through which the inflation and deflation of the air took place the volume of air required for inflation is reduced and, on the other hand, the inflation process goes on and on as well venting faster

In order to have the cover always ready for use, the inflation connection is advantageously provided with a pressurizing device connected, the cover formed in such a way it can be that the pressurization device, such as air pump, compressor or the like. With a buoyant ! Carrier is equipped with the roll-free end of the pillow is connected

The power supply to the buoyant pressurizing device from a known per se is advantageous extendable cable collection drum formed. But it is also possible to design the cover in such a way that the Stationary pressurization device arranged outside the water area is connected via an elastic pressure line to the connection of the cushion, which is advantageous the pressure line on one of *? and rollable cable collecting reel can be led *

../5 6 09820/0033

Palls the pressure pipe due to large pool dimensions does not have to be too long and does not apply too much when it is rolled up, the cable collecting reel can be part of the Be designed for the cushion

Of course, nothing stands in the way of making the entire pool cover fully automatically operable, for which appropriate elements are readily available.

For example, by pressing a button, the Drive for the air supply device actuated by which inflated the cushion from a check valve wirdo As the filling increases, the pillow rolls over automatically from the role, the role of course must be designed to be freely rotatable. Do you want the cover remove a toggle switch or a second push button that sets the roller drive in motion and that Check valve or a special blow-off valve opens. The roll-in speed must of course be the same as the inflation speed be adapted to the air.

The task at hand can be met, however, insofar as it is about pools that are housed in halls and are not too large acts, also solve in another way, namely by the skin develops as an inherently rigid surface that is attached to several Places with tension cords is connected, which tension cords on rollers on the hall ceiling to one

Under inherently stiff surface could for example » ^; a surface made of extremely light wood (balsa wood), which is accordingly moisture-proof or a surface as light plastic
