Definitions

  • the invention relates to a drive device for the cover of a liquid container, in particular a swimming pool, according to the preamble of patent claim 1.
  • the cover of a swimming pool serves, inter alia, the thermal insulation. By covering the swimming pool premature cooling of the water can be avoided. Furthermore, the cover serves as a protective device which prevents children from falling into the pool. Furthermore, the cover prevents leaves and dirt from getting into the water. Optionally, the cover should also be walkable or at least a load, such as a layer of snow, can wear. Usually covers are used, which consist of strip-shaped profile elements, which are flexibly coupled together.
  • a cover which can be pulled by means of a drive device via a bathtub and back.
  • a cabinet is provided outside the bathtub, within which a toothed roller is provided, which is supported by a shaft and driven by a motor.
  • the toothed roller can engage with their teeth in grooves provided in the flexible interconnected profile elements of the cover, and push them back and forth.
  • the cover is not wound up on the sprocket, but pushed past this in a matched to the cover memory channel.
  • the device therefore requires a drive device and a cover, which are specially adapted to each other.
  • this device is limited to smaller basins, since the memory channel can accommodate only a small number of flexibly interconnected profile elements, because the memory channel and the drive device itself take up much space. Furthermore, the entire device with the sprocket, the correspondingly adapted profile elements of the cover and the required memory channel is configured relatively complex.
  • the DE2854738A1 shows a guide which presses against the wound part of the cover and presses a developed part of the cover against a support rail.
  • the cover is therefore exerted by two sides of a pressure, which is why a friction results and the transport of the cover is hindered.
  • FR2607173A1 In the device of FR2607173A1 is located on the wound part of the cover also an outer tension element, which leads the cover on the top only partially. At the bottom, the cover is supported only when reaching a deflecting device, so there is a risk that the cover can fold down or up.
  • the present invention is therefore an object of the invention to provide an improved drive device, which allows the cover of a liquid container, in particular a swimming pool, extend and retract.
  • a drive device is to be provided, which allows to drive any covers that float on the water or guided along guide surfaces.
  • the drive device should take up little space and require no memory channel, so that larger covers can be accommodated within the room in which the drive device is provided.
  • the drive device which serves to transport the cover of a liquid container, in particular a swimming pool, and by means of which the flexible cover can be pushed over the pool and withdrawn therefrom, is installed or installable in a device space arranged separately from the liquid container, and comprises at least a cooperating with the cover winding shaft, optionally a mandrel or a coil which is coupled to a first drive unit.
  • the cover is preferably made of strip-shaped profile elements which are flexibly connected to each other.
  • the profile elements are connected by joints or elastic materials.
  • the profile elements are preferably rigid and have a low specific weight, so that they can either float on the water surface of the swimming pool or slide along guide rails.
  • the winding shaft serves to wind the cover, which can be guided via a deflection device to an outlet opening of the device space and at the end facing the winding shaft is coupled to at least one outer tension element, which abuts against the side facing away from the deflection of the cover, and these against voltage the deflection device presses, and which is held by a first pulling device and can be tensioned by this.
  • the first pulling device preferably comprises a coil on which the outer tension element can be wound up. In order for the process to take place automatically, the coil is preferably driven by means of the first or a second drive unit.
  • the cover With the tightening of the or the outer tension members, the cover is unwound from the winding shaft, guided over the deflection device and pushed over the liquid container.
  • the deflection device is preferably rotatably mounted. In this way, the corresponding end of the deflection device, for example a runner, can follow the changing diameter of the wound cover.
  • the outer traction element and the cover run parallel during extension. This is particularly advantageous particularly when the deflection device comprises sliding elements or one or more deflection rollers which are arranged along a correspondingly designed body. Furthermore, several pulleys can be used, which are enclosed by an endless belt. If the pulleys and / or or the endless belt are driven, the transport is additionally facilitated.
  • the deflection device is preferably arranged and / or configured such that the cover does not run in a straight line, but via a detour to the outlet opening of the device space.
  • the preferably extending from the winding shaft to the outlet opening extending body of the deflection is curved. Due to the rotatable mounting and the curved design of the body, the cover therefore runs along a curved path, whereby a uniform force distribution is achieved.
  • the deflection device can be positioned on one or the other side of the connecting line between the winding shaft and the outlet opening. When switching between the two variants, only a kinematic reversal occurs.
  • the at least one outer tension element and the cover therefore preferably run synchronously and parallel to one another in the region of the outlet opening.
  • a force from both sides on the cover By pressing the cover to the deflection takes place a force from both sides on the cover, whereby it is conveyed without slippage.
  • a plurality of outer and optionally several inner tension elements are provided, they are preferably distributed along the winding shaft at equal intervals, which ensures that a uniform force on the cover results.
  • single or combined pulling devices can be used.
  • traction devices with multiple coils which are driven by a single spool shaft.
  • At least one inner tension element which can likewise be wound onto the winding shaft and which is held by a second pulling device and can be tensioned by the latter is provided on the side of the cover opposite the outer tension element.
  • the cover is held by both sides of at least one inner tension member and at least one outer tension member and synchronously carried between them.
  • the tensioned outer and inner tension elements and the deflection device define the path along which the flexible cover is guided.
  • the second pulling device preferably comprises a coil driven by the first or a third drive unit, which serves to wind up the inner tension element.
  • the cover By tensioning the outer tension element and the inner tension element, the cover is therefore extended and conveyed through the outlet opening to the outside.
  • the tension members are deflected in a preferred embodiment in the vicinity of the outlet opening and guided to the traction devices, which are preferably electrically driven together or separately.
  • drive devices or traction devices can also be used, e.g. work by spring force.
  • the at least one outer tension element is guided via an upper exit roller to the first pulling device.
  • the inner tension element is guided via a lower exit roller to the second pulling device, wherein the upper exit roller and / or the lower exit roller are arranged as close as possible to the outlet opening of the device space that the cover is guided and transported optimally up to this area.
  • the outer tension element and the inner tension element are preferably made of plastic, metal or textile material.
  • flat straps or ropes are used as tension elements.
  • the dimensions of the tension elements are chosen depending on the material used.
  • band-shaped tension elements are selected with a width of 2 cm to 5 cm, which act vigorously but gently on the cover.
  • belt-shaped tension elements can also be selected in a wider range with a width of, for example, 1 cm to 20 cm.
  • Wire ropes can have a minimum diameter and take up little space, but are preferably used only when the cover is reinforced accordingly at the relevant points.
  • the bobbins or reels on which the tension elements are wound up are adapted to the tension elements used.
  • the ends of the tension elements are connected directly to the winding shaft.
  • the tension elements are preferably connected to the cover such that an end piece of the tension elements that can be connected to the winding shaft is exposed. In this way, the cover can be easily connected by means of the tension elements with the winding shaft.
  • the device While the pulling devices serve to pull out the cover, the device is retracted again by means of the central winding shaft and wound up.
  • the winding shaft is preferably driven in both directions and controlled accordingly. In this way, there is a relief of the traction devices when removing the cover. If several electric drives are operated simultaneously, they are synchronized accordingly by means of an electrical control.
  • the winding shaft and the at least one spool shaft are not rigid, but via balancing devices, such as differential gear, slip clutches or slip hubs, coupled together.
  • the drive shaft of a single drive unit preferably an electric motor
  • a first mechanical balancing device such as a differential gear or a slip hub and a freewheel
  • a second traction device is present, then the drive shaft of the first drive unit or the first spool shaft of the first traction device via a second mechanical compensation device, such as a differential gear, an elastic connecting device or a slip hub and a freewheel, coupled to a second spool shaft of the second traction device.
  • the compensation devices ensure that the rotational speeds of the preferably rigidly coupled to the winding shaft drive shaft and the spool shafts are adapted to each other, so that outer and inner tension elements are pulled with a constant force and tensioned evenly.
  • the cover is therefore always guided evenly and correctly wound up and unwound. Malfunction or malfunction of the drive device when extending the cover, which would require intervention by the user or maintenance personnel are avoided.
  • an optimal interaction of the various components of the drive device takes place. So that a uniform extension of the cover can be ensured, preferably two or more outer traction elements and preferably also inner traction elements are provided, which are driven by the associated first or second spool shaft.
  • the winding shaft is driven by a motor, which is preferably integrated in the winding shaft and thereby takes no further space and is also optimally protected.
  • the device space is preferably coverable by means of a lid, which is articulated on one or the other side or supported on the edge of the basin.
  • a lid which is articulated on one or the other side or supported on the edge of the basin.
  • waves or hinges are used to rotatably support the lid. In this way, it is easily possible to intervene in the non-flooded device space to perform maintenance. It is also possible to open the lid and pull the cover to the other side and e.g. to lay down on a lawn to perform a material test or cleaning work.
  • the lid is mounted such that between the pool wall, which separates the device space from the pool, and the lid, the slot-like outlet opening is kept free, so that the cover can be transported through them unhindered.
  • At least one console which serves to hold a support arm which is connected to the cover and stabilizes it, is fastened within the device space, on the outer wall opposite the pool wall.
  • FIG. 1 shows a drive device 1 according to the invention, which serves to transport the cover 10 of a swimming pool 2.
  • the flexible cover 10 can be pushed over the pool 2 and withdrawn from this again.
  • the drive device 1 is installed in a separate from the pool 2 device chamber 3, which is lockable by means of a lid 4. By separating from the pool 2, the device can be kept dry and protected from contamination and oxidation. Furthermore, maintenance work, in particular cleaning, on the drive device 1 can be carried out easily.
  • the drive device 1 comprises a drive unit 110 which has a winding shaft 11 which is coupled to a motor 111 and onto which the cover 10 is wound.
  • the winding shaft 11 is a conventional shaft, a mandrel, a spool or a drum.
  • the cover 10 is guided via a deflection device 14 to an outlet opening 35 of the device chamber 3, which is bounded by a basin wall 31 and the lid 4.
  • an outer tension member 12 At the winding shaft 11 facing the end of the cover 10 is connected to an outer tension member 12 and optionally an inner tension member 13. It is shown that the outer tension member 12, the cover 10 and the inner Tension element 13 is partially wound onto the winding shaft 11 and coupled thereto. Of central importance is the use of the outer tension element 12, which bears against the deflecting device 14 side facing away from the cover 10, and this presses under tension against the deflection device 14.
  • the outer tension element 12 is guided via a discharge roller 125 serving for deflecting to a first pulling device 120, which winds the outer tension element 12 onto a spool 122 on the basis of a drive unit 121.
  • the pulling device 120 thus makes it possible to tighten the outer tension element 12 and to set the winding shaft 11 in motion, so that not only the outer tension element 12 but also the flexible cover 10 is unwound from the winding shaft 11.
  • the outlet roller 125 is provided in the region of the outlet opening 35, for which reason the cover 10 is guided in a controlled manner from the outer tension element 12 to the outlet opening 35 and can exit via an outlet ramp 38.
  • the exit roller 125 is preferably at the end of the lid 4 or on a separate lever 129 (see FIG. 4a ) and can be held by this in an ideal position.
  • the deflection device 14 comprises two rotatably mounted deflection rollers 14A, 14B, around which an endless belt 149 is guided.
  • the cover 10 is pressed by the outer tension member 12 against the guide rollers 14A, 14B of the deflection device 14 and guided by this. On the cover 10, therefore, forces act from different sides, from the front and from above through the outer tension element 12 and from below through the deflection device 14, which pull these hold and when extending to the outlet opening 35.
  • the cover 10 is not guided on the shortest path to the outlet opening 35.
  • the deflection device 14 is therefore displaced outwards or curved outward in relation to this shortest path. Therefore, the cover 10 is pressed by the outer tension member 12 with a force against this shortest path until an equal force from the deflection device 14 acts on the cover 10 from the other side.
  • the cover 10 is therefore precisely guided along a curved path.
  • the second traction device 130 comprises at least one spool 132 driven by a drive unit 131, which serves to attract and wind up the associated inner traction element 13.
  • the inner tension element 13 is guided by the winding shaft 11 via the deflection device 14 and a lower exit roller 135 to the second pulling device 130.
  • the outlet roller 135 is also provided near the outlet opening 35, which is why the cover is guided precisely on both sides up to the outlet opening 35.
  • the outer tension member 12 and the inner tension member 13 define a path which the flexible cover 10 must pass through, so that it can be easily pushed outwards without being able to escape upwards or downwards. It can be seen that the elements of the drive device 1 within the device space 3 occupy only little space, which is why much free space for receiving the cover 10 is present. Even with small dimensions of the device space 3, large covers 10 can therefore be accommodated and large liquid containers or swimming pools 2 can be covered.
