Definitions
- the present invention relates in general to a cover or a protection intended for a pool unit within a pool system, normally entitled a "pool cover", and more specifically to a lightly flexible cover or pool protection formed as a surface structure with a selected surface extent, intended for a pool or pool unit in such a pool system and serving as a mechanically covering protection, where said cover is adapted, to be able to assume a first end position, covering the pool or pool unit, and a second end position, exposing a pool or pool unit, and, where necessary, in addition any interjacent position.
- pool system is taken to signify a system which displays a pool unit filled with a liquid or water which may advantageously display a pump unit adapted to circulate by pumping said liquid or water through one or more filter units, as well as one or more metering devices intended to supply to the water chemicals, such as chlorine, in order to keep the liquid or water accumulation clean and free of bacteria and algal growth.
- a pump unit adapted to circulate by pumping said liquid or water through one or more filter units, as well as one or more metering devices intended to supply to the water chemicals, such as chlorine, in order to keep the liquid or water accumulation clean and free of bacteria and algal growth.
- the present invention relates to such a cover intended for a pool system where the cover is adapted to be able, in relation to an edge, to cooperate with a guide arrangement or similar anchorage means, said cover being structured to be able to be oriented at a predetermined and recommended minimum distance, designated as a safety distance, from the upper surface of a liquid- or water body enclosed in the pool or pool unit.
- liquid- or water accumulation disclosed here will hereinbelow merely be designated as a body of water.
- present invention should be considered as a direct further development of the invention and embodiment disclosed and described in Swedish Patent Application number 04 02630-8, filed under the title "Pool protection with active temperature regulation", and the contents of this application are to be considered as a part of and be embodied in the contents and text of this present application.
- a cover intended for a pool system the cover being lightly flexible, formed as a surface extending structure and serving as a protection.
- Said cover is adapted, in the fully extended state, to be able to assume an end position and wholly covering the pool or pool unit, and in a rolled-up or folded state to be able to assume an end position and exposing the pool or pool unit, and where such a cover is normally adapted to be capable, when needed, of assuming any interjacent position.
- a cover of the type under consideration here may normally be cooperating in edge- related manner with a guide arrangement or similar fixing means, said cover per se and/or with the aid of separate supporting and/or lifting means, being adapted, in such instance, to be oriented at a predetermined distance, normally 180 mm or slightly more, from the upper surface of a body of water enclosed by the pool.
- Pool covers and protectors of the type associated herewith have, in such instance, been designed to be self-supporting in order, in addition, to be able to absorb specifically active instantaneous outer forces and have thus not been designed and/or dimensioned to support additional point loadings or forces and/or surface-distributing weights or forces which could press down the pool protection in a direction towards the surface of the body of the water and thereby reduce the above-disclosed safety distance to below the stipulated 180 mm.
- Covers and pool protectors for pool systems with associated pool or pool unit have been produced with a view to being able to preclude and/or eliminate the following situations, however some are disclosed which are novel and associated with the present invention.
- a cover of the associated type or a pool protection should per se be constructed and/or together with mechanical reinforcements, be constructed to be able to support point-active forces such as an adult. The adult in question should be able to move away from the pool protection without running the risk of drowning.
- the pool protection may not sink down to and past the surface of the water because of the weight of the child.
- the securing of the pool protection or cover along the pool unit or pool must be capable of being made so tight that unwelcome small animals will not be able to creep in under the cover and gain access to the pool. 4. Prevent particles, such as sand, litter, leaves, seeds etc., from polluting the water of the pool unit.
- the pool protection should be wholly covering and normally be oriented higher than the edge of the pool so that sand and leaves may be blown off the pool protection. Bird lime and branches landing on the pool protection can be washed off or removed in connection with the stowing away, by rolling up, of the pool protection.
- the largest temperature-reducing effect on the pool water is caused by the energy conversion which takes place when the pool water evaporates. A covering of the surface of the water reduces this evaporation and, as a result, a reduction in temperature.
- the consumption for a normal family pool of 4 x 8 m is between 10,000 and 20,000 kWli, which is the largest operational cost for such a pool installation.
- the thermal absorbing units of solar power apparatus can then be utilised as evaporation cooling by sprinkling a layer of water on these units, which is then allowed to evaporate and thereby cool the pool water circulating in the suntraps.
- a liquid-absorbing blanket may be placed on the suntrap units.
- the pool protection should not cover any part of the pool but should be able to be rolled-up or folded up beside the pool, preferably along its short side.
- a pool protection with free-bearing beams and/or rods will have a limitation in relation to its mechanical strength as a result of the size of its span.
- pool unit protection coverings or pool protectors are also part of the state of the art:
- a pool protection which consists of supporting beams or rods which are oriented transversely across the pool or pool unit between longitudinal side edges and locking each rod against parallel guides.
- the beams or rods are connected to a PVC sheet.
- the protective sheet When the pool protection is spread over the pool unit, the protective sheet is taut between the beams and the pool unit is covered, when the pool unit is open the rods are retracted to the one short side of the pool unit and the sheet lies in folds between the beams or rods.
- a floating flexible covering for outdoor pools comprising a suntrap apparatus for the body of water of the pool unit with the aid of inflatable pontoons.
- the pool protection serves the purpose of only acting as a suntrap and a protection against evaporation.
- a method of manufacturing floating, flexible pool covers with integrated suntraps is provided.
- the pool protection is provided with absorbers related to the suntrap equipment and consisting of two plastic films joined flat face to flat face so that channels may be formed therein between the plastic films.
- the absorbers may also be provided with integrated buoyant bodies.
- the pool protection is merely a suntrap and offers protection against evaporation and thereby solves problems numbers 4, 5, 6, 7, 8, 9, 11, 12 and 13.
- a floating, flexible pool protection with integrated absorbers relating to suntrap equipment consist of two thin panels (flexible and roll-up) joined together face to face.
- the upper panel is planar and the lower panel has elevations.
- the entire absorber can float on the pool water because of the cavities provided.
- the whole of the absorber can be laid as a lid from a pool edge to an opposing pool edge.
- the pool protection is merely a suntrap and affords protection against evaporation and contamination.
- the equipment solves problems numbers 4, 5, 6, 7, 8, 9, 11 and 12.
- a foldable or roll-up pool cover or pool protection with absorbers relating to suntrap equipment is provided.
- the pool protection includes a floating sheet, for example a common bubble plastic coating, where a thin plastic film is secured above in the form of tubular channels of a diameter of, for example, 20 cm.
- the pool protection is merely a suntrap and affords protection against evaporation and contamination.
- the equipment solves problems numbers 4, 5, 6, 7, 8, 9, 11 and 12.
- Air is pumped in between the films which entails that the pool protection can float on the pool water.
- the pool water is pumped through the channels between a transparent plastic film and a black plastic film.
- the covering is merely a suntrap and affords protection against evaporation and contamination.
- a cover or pool protection intended for a pool system which is lightly flexible and formed as a structure covering a surface extent over a pool or pool unit and serving as a protection, where said cover is adapted to be able to assume an end position covering the pool unit or pool and an end position exposing the pool unit or pool, and normally each interjacent position, in that said covering may, in edge-related fashion, cooperate with a guide arrangement or similar anchoring means, said cover being oriented, by one or more support means, in any event at one predetermined distance from the upper surface of a body of water enclosed in the pool, to cause said cover or pool protection to be integrated with and/or adapted to support water-filled channels and where said channels are adapted to form part of one or more thermal energy absorbing units included in suntrap equipment, whereby a water portion heated by solar
- each sheet- supporting and/or sheet carrying means in the form of a beam or a rod is adapted to cooperate each with a carriage related each to a guide and that said water-filled channels are wholly or partly oriented at right angles to said rods.
- the present invention takes as its point of departure or conception the prior art technology as disclosed by way of introduction for a cover or pool protection intended for a pool system, the protection being lightly flexible and formed as a surface extending structure covering a pool or pool unit and serving as a protection, where said protection is adapted to be able to assume a first end position covering the pool unit or pool and a second end position exposing the pool unit or pool, and, where necessary, every interjacent position, in that said cover or pool protection should be adapted to cooperate in edge-related fashion with a guide arrangement or similar means, said cover being oriented, by supporting means, at a predetermined distance from the upper surface of a body of liquid or water enclosed in the pool.
- the present invention particularly discloses that the prior art technology be complemented in that said cover be integrally formed with and/or adapted to support liquid- or water-fillable channels, and where said channels are to be adapted to be included in one or more thermal energy absorbing units, included in one or more suntrap apparatuses, and that a water portion, heated by solar energy in water-filled channels is adapted, preferably by the intermediary of short conduits, to be heat exchanged with the body of water enclosed in said pool or pool unit.

- a pool or pool unit 3 in which is enclosed a body of water supplied with chemicals which, hereinbelow, will be designated a body of water 2.
- portion 2a of this body of water 2 is pumped, by the intermediary of a pump unit 4
- FIG. 2 is intended to illustrate in a perspective presentation a pool unit 3 with a mounted pool protection 10 displaying a cover or here designated pool protection 10 intended for a pool system 1, the pool protection being lightly flexible and formed as a structure covering a pool or pool unit and serving as a protection.
- Said pool protection 10 is adapted to be able to assume a first end position, exposing the pool unit or pool, according to Fig. 7, and a second end position, covering the pool unit or pool, according to Fig. 8, and, where necessary, each interjacent position.
- the pool protection 10 is disposed to cooperate with an edge-related 10a, 10b guide arrangement 11 or similar anchorage and supporting means, said pool protection 10 being of a construction or being coordinated with support means 12 so as to be oriented at a predetermined distance 13, a safety distance, from the upper surface 2' of a body of water 2 enclosed by a pool or pool unit.
- said pool protection 10 is to be integrally formed with and/or adapted to support narrow liquid-fillable or water-filled channels 14, 14a, where said channels are adapted to form part of one or more sets of thermal energy absorbing units, designated 6a, 6b, in Fig. 3, included in one or more suntrap apparatuses 6, and that a water portion 2b from these water-filled channels 14, 14a substantially heated by solar energy is adapted to directly heat exchange with the body of water 2 enclosed in the pool or pool unit, in the manner which was illustrated in principle previously with reference to Fig. 1. More particularly, the present invention discloses that these water-filled channels 14, 14a within the thermal energy absorbing units 6a, 6b, are integrally structured between two or more lightly flexible sheet strata.
- the sheet stratum forming the upper side of the pool protection 10 is to be applied with said water-fillable channels 14, 14a within mutually series-connected and/or parallel-connected thermal energy absorbing units 6a and 6b, respectively.
- the embodiment further illustrates that, between guides 11a, 1 Ib related to the guide arrangement, there extends a sheet supporting and/or sheet bearing means 12 dimensioned and adapted in order, from the viewpoint of safety, to be able to support the weight of a person, but also to be able to support the weight of utilised heat absorbing units 6a, 6b, included in the suntrap apparatus 6, as well as with channels 14, 14a filled with water portions, intended for heat exchange and heat supply.
- a pump unit 4 is also illustrated in Fig. 2 and is adapted to supply a water portion 2b heated by solar energy to a heat exchanger, surrounded by a body of water enclosed in the pool or pool unit, or more preferably direct to the body of water 2 enclosed by the pool or pool unit.
- a selected number of carriages lie, Hd, associated with the guide arrangement are disposed to cooperate with parallel guides 11a, l ib included in said guide arrangement 11, that each sheet supporting or sheet bearing means, in the form of a rod or a wire 22, is adapted to cooperate with a carriage lie, Hd for its guide 11a, lib and that said water-filled channels 14, 14a are wholly or partly oriented at right angles to said rods or wires 22.
- one or more thermal energy absorbing units included in one or more suntrap apparatuses, are to be oriented in order to be exposed to thermally insulating air strata, one on each side of the pool protection, and thereby be able to be selected for an absorbing thermal radiation and/or sunlight only from the upper side.
- said units and associated components for the pool protection are to be structured with prepared thermal absorbing surfaces facing upwards and prepared thermal insulating surfaces facing downwards and for the formation of the upper surface of the disclosed safety distance.
- the utilised thermal energy absorbing units are then to be oriented such that they may absorb thermal radiation and/or sunlight substantially from above and that they are not to absorb any appreciable heat from the surface of the water, by the intermediary of thermal conduction, as is the case in prior art technology.
- the present invention discloses that the economically most advantageous method of heating the body of water of the pool unit is with the aid of suntrap apparatuses.
- a pool protection 10 has the heat absorbing unit of the suntrap apparatus integrated, no free-standing roof or free land surfaces required for these units.
- the energy conversion from utilised suntrap apparatuses may be rendered more efficient.
- FIG. 3 to 8 it is there illustrated how two parallel rows of units 6a are oriented at the left-hand side and how two parallel rows of units 6b are oriented to the right-hand side, with a freely interjacent section 10c.
- the unit 6a and the unit 6b are both formed each from a set of eight sections, a set 16a of four series-connected sections 25, connected in parallel with a second set 16b of four series-connected sections 25a for the unit 6a.
- reference numerals 20, 20' and 21, 21' are intended to illustrate anchorages, each for a shroud line 22, 22'.
- Reference numeral 23 relates to the pool edge, 24 to an end beam, 25 to an absorber unit or a section, 26 to drainage holes connected to the mains, 27 to a pool pocket, while reference numeral 28 illustrates a path and 29 a skirt arrangement.
- Reference numeral 30 is intended to indicate a suction conduit, reference numeral 31 a filter, 32 a thermostat valve, 33 a hose enclosed to one of the units 6a and 6b, 34 a pool temperature indicator, 35 a temperature indicator for a suntrap unit, 36 a rope and 37 differential thermostat.
- the present invention has for its object to offer a total solution to the problems existing in connection with pool protection 10 of pools 3.
- the pool protection 10 consists of a reinforced polymer sheet which is dimensioned to cover the pool 3. It has high UV, elemental and temperature resistance and withstands all forms of chemicals which normally occur in swimming pools 3. The reinforcement renders it configurationally stable and so strong that it withstands both those pressure and point loadings which the sheet may normally be subjected to.
- the sheet On its longitudinal side, the sheet is anchored in carriage-formed anchorages l ie, Hd, with means 12 or sheet supporting shroud lines 112 disposed in parallel.
- the sheet is secured directly in the pool edge 23, and in the front edge in an end beam 24.
- the pool protection 10 When the pool is utilised for bathing of swimming, the pool protection 10 is folded up in a pool pocket 27. When the pool protection 10 is closed, there must be an air pocket 13 between the surface 2' of the water and the pool protection 10 so that a swimming remaining there can breath.
- the anchorage along the longitudinal sides is put into effect in that the sheet 1Od is wedged fast in an opening on the anchorage 20.
- the carriages run in a path 28 along the edge of the pool 23.
- a folded skirt 29 seals between the pool edge 23 and the pool protection 10 so that sand and leaves etc. cannot blow down into the pool.
- the anchorage in the front edge is shown in greater detail in Fig. 6.
- a beam 24 may be secured in the front edge of the pool protection 10.
- the beam 24 has been allocated a plurality of functions.
- the first function is that it holds up and out the sheet 1Od towards the longitudinal sides so that the anchorages 20 slide easily along the path 28 on the pool edge 23.
- the second function is that, at the outer edges of the beam 24, a V-shaped rope 36 is secured, which is used to draw the pool protection 10 in and out.
- the third function is that the beam 24 is anchored with straps or hooks in the pool edge 23 at the front edge of the pool.
- a folded pool protection 10 is illustrated in greater detail in Fig. 7.
- the suntraps 25, 25a in the form of absorbers are manufactured from reinforced polymer sheet fixed in parallel series on the pool protection 10.
- the suntraps 25 are flexible and may be folded over the transversely directed shroud lines 112 and pulled towards and to the pool pocket 27 so that the pool unit 3 will be open for bathing and swimming activities.
- Water portions 2a, 2b of the water 2 in the pool 3 become heat carriers by the intermediary of the suntrap units 6a, 6b.
- the circulation pump 4 sucks up water within the heat carrier 2a (the pool water) through a suction conduit 30 from the pool unit 3 and forces it, through a filter 31, through a thermostat valve 32 via the suntrap hose 33, to the suntrap unit 6a and to an outlet 38 for the water 2b heated in the suntraps being recycled to the pool unit 3.
- a control system with differential thermostat 37 indicators or sensors, via an indicator 34, controls the temperature in the pool water 2 and, via an indicator or sensor 35, the temperature within the suntrap units 6a.
- the thermostat valve 32 opens the circulation via the suntrap unit 6a, so that heat is delivered to the pool unit 3.
- the heat system supplies thermal energy until any set temperature has been achieved. Thereafter, the valve 32 closes.
- the circulation pump 4 starts and a sprinkler (not shown) pours water on the pool protection 10.
- the evaporation which then starts takes its energy from the absorbers 25a and lowers the temperature of the heat carrier, which in turn cools the liquid in the pool unit.
- a water absorbing blanket (not shown) may be placed on the suntraps.
- the present invention is naturally not restricted to the embodiment disclosed by way of introduction above, but may undergo modifications without departing from the scope of the inventive concept as disclosed in the appended Claims.
- every illustrated unit and/or circuit may be combined with every other illustrated unit and/or circuit within the scope of the present invention in order to be able to attain the desired technical function.
