Definitions

  • the invention relates to a pool cover device with a winding roller, a cover that can be wound up and unwound on the winding roller, a winding motor for winding the cover onto the winding roller and unwinding the cover from the winding roller, and a pulling motor for pulling the cover off the winding roller.
  • Pool cover devices are used in a well known manner to cover pools such as swimming pools. With the covering, a liquid in the basin, such as water, is covered and protected. For example, the water can B. be protected from evaporation and thus from cooling by otherwise occurring heat withdrawal during evaporation. In addition, it can be prevented that z. B. Children falling into an unattended pool. It can also be used to effectively remove dirt, e.g. B. falling leaves, are kept out of the water.
  • a cover of known pool covering devices that is wound up on a winding roll can conventionally be pulled off the winding roll by means of a pulling motor. After being peeled off in this way, the cover covers an opening of a pool in an unwrapped state. The opening is conventionally located above a water surface of the pool.
  • the cover is designed to be wound or rolled and wound up on the winding roll is usually positioned close to the pool.
  • the winding roll is a shaft on which the cover is wound when the cover is not spread over the pool.
  • the cover for covering or covering the pelvis is rotated or unrolled by the winding motor in an unwinding direction and pulled by the pulling motor over the opening of the pelvis in a pulling direction.
  • it may be difficult to reliably cover the pool since conventionally the cover cannot always be rolled out neatly and largely evenly over the opening of the pool. Above all, folds or bulges and indentations transverse to the direction of pull are not always avoided.
  • the unrolled cover is often not sufficiently resistant to undesired deformation or bending transverse to the pulling direction.
  • the invention is based on the object of creating a pool cover device with which a cover can be deployed particularly evenly and stably over the opening of a pool and, in particular, stably positioned there.
  • a pool cover device with a winding roller, a cover that can be wound up and unwound on the winding roller, a winding motor for winding the cover onto the winding roller and unwinding the cover from the winding roller, and a pulling motor for pulling the cover off the winding roller .
  • the removal of the cover from the winding roll by means of the traction motor is braked by the winding motor.
  • the cover When removing the cover from the winding roll, the cover is pulled off the winding roll by means of a pulling force of the pulling motor and at the same time pulled in a pulling direction by means of the pulling motor, in particular over an opening of a basin.
  • the traction motor is braked by the winding motor, in particular in that the traction motor and the winding motor are designed to be matched to one another and are driven in an adapted manner.
  • both motors run in such a way that the winding motor brakes the pulling motor.
  • Such a braking according to the invention ensures that the cover is reliably tensioned while it is being pulled off and unwound from the winding roll. Tensioned in this way, an undesired formation of folds in the cover, in particular over the opening, and a disruptive formation of sacks in the cover on the winding roll are reliably prevented.
  • the traction motor thus interacts with the braking winding motor for covering the pool in a special way and in a coordinated manner.
  • the traction motor preferably drives a traction roller or pull-out roller, with which the cover can be pulled from the winding roller.
  • both the winding motor and the tension motor are adapted to set the respectively associated winding roller or tension roller in a rotational or rotational movement.
  • the traction roller is to be driven by the traction motor in such a way that the cover is to be pulled off the winding roller, and at the same time the winding roller is to be driven by the winding motor in such a way that the cover can be unwound from the winding roller when it is braked or tensioned.
  • a diameter of about 10 to 20 centimeters for the winding roll when the cover is not wound up has proven to be particularly suitable for this purpose.
  • the cover that can be wound can in principle be designed with a film and therefore requires particularly little space or space on the winding roll.
  • the foil weighs relatively little, so that the foil can be stretched effortlessly using the traction motor and the braking winding motor.
  • the film can also be designed as a fabric film or lattice film.
  • a fabric foil has a fabric lattice and is therefore relatively stable with respect to tensile forces acting and transverse forces acting transversely to a tensile direction.
  • the fabric film can be wound up on the winding roll to save space and, because of its low weight, can be stretched with little effort.
  • the cover is preferably designed with several individual sections that can be wound up and unwound and are connected to one another.
  • the individual section is in particular designed to be comparatively rigid.
  • a rigid section means here that, in comparison to a film or fabric film, the section adapts itself only slightly or not at all to the winding roll with its curvature when it is rolled up onto the winding roll.
  • the individual section can still be somewhat deformable and elastic. With such sections, the cover is particularly stable against bending or compressive forces occurring transversely to the pulling direction when it is pulled off the winding roll and when it is deployed over the pool. It can thus be prevented that things and people fall into the pool covered with the cover.
  • the individual, in particular rigidly designed section is an elongate, strip-shaped element.
  • the individual elements are pivotably connected to one another along their longitudinal extent, so that the cover is designed as a roller cover or roller shutter cover similar to a roller shutter, roller shutter or blind.
  • the cover on the winding roll requires relatively little space and is at the same time so stable that when it is deployed over the pool, things and people are prevented from falling into the pool.
  • the pool is preferably a swimming pool. It can also be any other type of basin or container, such as a container or truck bed, be optionally covered by the pool cover device according to the invention.
  • the pulling motor and the winding motor can be activated at the same time in order to remove the cover from the winding roll.
  • permanent prestressing is produced in particular between the traction motor and the winding motor in a mechanical manner, for example by means of a resilient or yielding element.
  • the cover is then pretensioned from the start, while the actual pulling off or unwinding from the winding roll takes place. With such a pretensioning before the pulling off, an initial sack formation on the wound roll is already prevented. In this way, the cover can be pulled off the winding roll particularly evenly and spread out over the pool.
  • the winding motor is advantageously activated in the same direction as or along an unwinding direction of the winding roll for removing the cover from the winding roll.
  • the traction motor is activated in one traction direction.
  • the pulling direction corresponds at least essentially to the unwinding direction.
  • the motors are designed in such a way that they are coordinated with one another in such a way that the winding motor implements less movement on the winding roll than the traction motor on an associated traction roll.
  • the pull motor is activated with a pull-off force pulling on the cover, which is greater in magnitude than a pushing or tracking unwinding force exerted on the cover by the winding motor. Since the braking unwinding torque of the winding motor is always largely the same, the unwinding force generated thereby increases as the radius of the winding roll decreases during unwinding. At the same time, the unwinding speed, ie the unwinding distance covered per unit of time on the winding roll, decreases as the radius of the winding roll becomes smaller. The pull-off force of the pull motor and its pull-off speed remain largely the same with the pull roller remaining almost the same.
  • the winding motor is also advantageously activated at a winding speed that is lower than a pulling speed at which the pulling motor is activated in order to pull the cover off the winding roll.
  • the winding speed of the winding roll is kept largely constant during removal.
  • the winding speed of the winding roll is preferably 2 to 8 revolutions per minute, particularly preferably 4 to 6 revolutions per minute and very particularly preferably about 5 revolutions per minute.
  • the pulling speed of the pulling roller is also kept at least almost constant during the pulling off.
  • the pulling speed of the pulling roller is preferably 4 to 16, particularly preferably 8 to 12 and very particularly preferably about 10 revolutions per minute.
  • the train speed Pull roller is preferably about one and a half to three times as large and particularly preferably about twice as large as the winding speed of the winding roll.
  • the initially generated prestressing force is thus kept relatively constant during the pulling off, so that the cover can be pulled off particularly evenly.
  • the winding up of the cover onto the winding roll by means of the winding motor is also advantageously braked by the traction motor. Braking in this way ensures that the cover is reliably tensioned even while it is being wound onto the winding roll. Undesirable formation of folds and sacks in the cover on the winding roll are thus also avoided in the winding direction.
  • the winding motor and the pulling motor are advantageously activated at the same time for winding the cover onto the winding roll.
  • the cover is already held under tension before it is actually wound onto the winding roll. Bag formation on the winding roll is avoided right from the start of the winding process, so that the cover can be wound onto the winding roll in a particularly uniform and compact manner.
  • the traction motor is activated in the direction of or along the winding direction of the winding roll, so that both motors again have the same direction of action for winding.
  • the two motors are designed in such a way that they are coordinated with one another in such a way that the tension motor means that less movement is achieved on the tension roller than the winding motor on the associated winding roller.
  • the traction motor thus has a braking effect on the winding motor.
  • a particularly evenly stretched cover is achieved when the cover is wound up with relatively little effort and energy consumption.
  • the winding motor is advantageously activated with a winding force pulling on the cover, which is greater than a pushing or tracking force exerted on the cover by the pulling motor.
  • the thrust or tracking force exerted by the traction motor on the cover acts in the winding direction.
  • the cover is advantageously coupled to the traction motor by means of at least one traction element.
  • a traction roller is preferably provided for coupling the at least one traction element to the traction motor.
  • the individual tension element can be wound onto the tension roller, in particular by means of the tension motor, and the individual tension element can be unwound from the tension roller, in particular by means of the winding motor.
  • the cover When the cover is pulled off and wound up from and onto the winding roller, it rotates or winds only the individual tension element around the tension roller and not the cover. This avoids material wear on the cover and the pull roller that would otherwise be caused by friction.
  • a particularly low-wear basin covering device is created.
  • the at least one tension element is preferably pretensioned, in particular by means of the tension motor. Prestressed in this way, the individual tension element is protected in a stable manner against undesired movements, in particular transversely to the direction of tension. In this way, the individual tension element does not swing back and forth, so that the individual tension element cannot undesirably get caught or twisted.
  • the individual tension element is particularly preferably already pre-stressed in the idle state. When the cover is pulled off and wound up, a further tensile stress is then exerted by the pulling motor on the individual pulling element.
  • the winding motor is initially deactivated, while the tension motor is activated and, in particular, rotates in the process.
  • the traction roller driven by the traction motor rotates accordingly, whereby the at least one traction element is wound around the traction roller and pretensioned.
  • the winding motor activated in addition to the pull motor.
  • the winding motor rotates in the same direction as the pull motor during the pull-off and, like the pull motor, rotates at a largely constant number of revolutions.
  • the winding motor advantageously has a lower number of revolutions than the traction motor. It has been found that the initial tension that has been set is retained while the cover is being pulled off.
  • the at least one tension element is particularly preferably designed as a belt or band.
  • a belt is an elongate, narrow and flat strip which, particularly on its flat side, rests particularly well on the traction roller in a force-transmitting manner. This reliably prevents the tension element from slipping on the tension roller and the windings wound up there slipping off against one another when the tension element is wound onto the tension roller.
  • the cover has two opposite longitudinal sides with a longitudinal extension in the direction of pull of the traction motor and two opposite broad sides with a width extension transverse to the direction of pull.
  • a tension element is provided on each longitudinal side of the cover, directed along the longitudinal extent of the cover.
  • the cover is thus also tensioned across its entire width transversely to the direction of tension. With such an additional width tension, the cover can be pulled particularly stably across the width of the pool.
  • the cover is stretched stably over the pool not only in the longitudinal direction but also in the width direction. Tensioned in this way, one person in particular can be safely prevented from falling into the pool.
  • the at least one tension element is advantageously coupled to at least one holder protruding from the cover.
  • the individual tension element is preferably connected to the holder in a non-positive or positive manner, while the holder is arranged on the cover, in particular transversely to the direction of tension. Arranged in this way, the individual holder is located outside the cover as a pick-up point. This means that the entrainment point is easily accessible and easy to couple with the associated tension element.
  • At least one holder is preferably arranged transversely to the pulling direction on each longitudinal side of the cover.
  • at least one holder is particularly preferably provided opposite one another on each longitudinal side for a particularly uniform distribution of force.
  • the individual holder is directed along the width of the cover.
  • the cover with the at least one holder and the associated tension element is designed to be very flat. Designed in this way, points of attack for disruptive external influences, such as wind and weather, are avoided.
  • the individual holder is preferably designed with an elongated shape, similar to a bolt or pin. The holder then has a longitudinal extension which is directed along the width extension of the cover for the advantages mentioned.
  • the cover is advantageously guided according to the invention by means of at least one roller, in particular when unwinding from the winding roller and when winding onto the winding roller. Guided in this way, the cover can be pulled over the pool with particularly little friction, which saves strength and energy.
  • the at least one roller or roller is preferably arranged on the cover itself, in particular on each longitudinal side of the cover.
  • the roller arranged in this way is then guided on an edge of the basin or preferably in an associated running rail or guide rail arranged on the basin.
  • the at least one roller is preferably arranged on at least one roller conveyor.
  • the individual roller conveyor advantageously comprises a plurality of rollers which are arranged compactly next to one another. With the several rollers, a particularly low-friction and at the same time compact guiding of the cover is achieved.
  • the cover is advantageously guided in the pulling direction by means of at least one guide rail.
  • the cover is stabilized with the single guide rail during peeling and unwinding from the spool and winding onto the spool when moving across the pool. This achieves additional stabilization of the tension acting by means of the winding motor and the tension motor.
  • An associated guide rail is preferably arranged on the longitudinal side of the cover for further stabilization. Two guide rails are thus provided in the pulling direction, between which the cover is guided on its longitudinal sides.
  • the cover is particularly preferably guided by means of the at least one tension element, which is arranged in one guide rail each. Arranged in this way, each tension element is protected from environmental influences and dirt.
  • the cover is very particularly preferably guided in the at least one guide rail by means of the at least one holder. This means that only the individual holder is exposed to friction with the associated guide rail and not the cover. The material of the cover is therefore protected and protected against wear.
  • the individual holder is preferably made of a particularly wear-resistant material and can be easily and inexpensively replaced as a spare part if required.
  • a strip within the guide rail for covering the individual tension element arranged in the guide rail is additionally preferred provided to the outside. Covered in this way, the individual tension element is protected from dirt and from dangerous intervention and snagging by a user during operation.
  • the at least one roller which is preferably designed with at least one roller conveyor, is advantageously arranged on the individual guide rail.
  • the cover is thus stable and at the same time guided with little friction.
  • the individual roller or roller conveyor is provided well protected within the associated guide rail and preferably below the cover, the associated holder and tension element.
  • a sealing and cleaning element is preferably arranged at the entrance of the guide rail, that is to say on the side of the guide rail which faces the winding roll. In this way, the tension element guided in the guide rail is continuously cleaned of adhering dirt during operation.
  • At least one spreading element is advantageously provided on the cover, which is guided in the individual guide rail.
  • the spreading element braces itself against bending transversely to the direction of pull, which prevents bending in wind and weather and stepping on the spread cover.
  • the at least one guide rail is preferably arranged at a distance above a water surface of the water in the basin.
  • the distance creates additional insulation to protect against evaporation of the water.
  • the cover touches the water and is exposed to additives that may be present there, such as chlorine. This protects their material.
  • At least one deflection roller for deflecting the pulling direction between the pulling motor and the winding motor intended.
  • the pool cover device can thus be flexibly adapted to it depending on the environment and space requirements.
  • the traction motor with the associated traction roller and the winding motor with the associated winding roller are preferably arranged on just one side of the basin in a particularly space-saving and compact manner.
  • the at least one deflection roller is then at least one tension deflection roller, which is arranged on the side of the basin opposite the winding and tension motor.
  • the direction of pull is preferably deflected by approximately 180° by means of the individual pull deflection roller.
  • a train deflection roller is preferably arranged within a guide rail.
  • the individual tension element is coupled to a holder that projects laterally from the cover transversely in the direction of tension, so that the individual tension element is positioned laterally outside the cover.
  • the tension roller thus pulls the individual tension element laterally past the cover to be wound up or wound up on the winding roller, unhindered and without friction losses.
  • a pulling element and a holder that projects laterally and is coupled thereto are particularly preferably provided on each longitudinal side of the cover.
  • the tension roller and the preferred individual guide rail are advantageously arranged above the winding roller.
  • the tension roller is particularly advantageously positioned behind the winding roller in relation to a pool edge or in the direction of tension.
  • the at least one deflection roller is preferably designed as at least one winding deflection roller, which is arranged close to the winding roller in the pulling direction.
  • the direction of pull is deflected with the winding deflection roller at a deflection angle of preferably from about 0° to 90° and particularly preferably from about 20° to 70°.
  • the winding roll can thus be varied in its installation height as required.
  • the winding deflection roller is arranged in front of the at least one tension deflection roller in the tension direction. In this case, the winding roller is preferably positioned below the tension roller and the winding deflection roller.
  • the invention is also aimed at a method for covering and uncovering a pool with the aforesaid pool covering device.
  • the removal of the cover from the winding roll is braked by the winding motor by means of the traction motor.
  • the tension motor is advantageously activated in succession in time first and only then is the winding motor activated.
  • the winding motor is preferably activated in the direction or along the unwinding direction and the pulling motor is activated in the direction or along a pulling direction that is directed in the same direction as the unwinding direction.
  • the winding of the cover onto the winding roll by means of the winding motor is braked by the traction motor.
  • the winding motor is preferably activated first in chronological succession and only then is the tension motor activated.
  • the traction motor and the winding motor are preferably activated along the winding direction of the winding roll.

  • the pretensioning takes place in that the winding motor 42 is initially not activated or disconnected and only the traction motor 46 causes the traction roller 48 to rotate in the traction direction 50 .
  • the tension elements 52 fastened to the tension roller 48 are wound onto the tension roller 48 in the direction of tension 50, so that the tension elements 52 and the cover 18 coupled thereto are correspondingly pretensioned. Only then is the winding motor 42 activated or clamped to it.
  • a common switch (not shown) is provided, which is designed in particular as a contactor, so that the winding motor 42 and the tension motor 46 run on the same contactor, so to speak.
  • a star connection is preferably provided for this purpose.
  • the winding motor 42 is activated in such a way that the associated winding roll 16 is set in a rotary motion, which is directed in the unwinding direction 44 .
  • the unwinding direction 44 points in the pulling direction 50, so that both the winding roller 16 and the pulling roller 48 rotate in the same direction.
  • the winding motor 42 and the winding roll 16 coupled to it rotate at a lower speed or winding speed than the traction motor 46 with its traction speed and the traction roll 48 coupled to it the movement path covered by the tension elements 52 on the tension roller 48.
  • the braking effect of the winding motor 42 on the tension motor 46 when the cover 18 is pulled off the winding roller 16 is thus achieved. Braked in this way, the pulling motor 46 is always under tension when it is pulled off and thus exerts a maximum pulling force with the greatest torque.
  • the cover 18 is thus pulled in a stable manner over the entire basin 12 within the two lateral guide rails 30 by means of the pulling motor 46 .
  • a pulling speed of about 10 revolutions per minute and a winding speed of about 5 revolutions per minute have proven to be particularly advantageous here.
  • both motors 42 and 46 run at a constant speed, with the result that the prestress achieved during prestressing is largely retained.
  • the cover 18 is wound onto the winding roll 16 again.
  • the winding motor 42 is activated to rotate in the winding direction 40 opposite to the unwinding direction 44 .
  • the traction motor 46 is activated in the winding-up direction 40, which brakes the winding motor 42 in the process.
  • the cover 18 is thus pulled correspondingly tensioned by the winding motor 42 in the winding direction 40 from the tension roller 48 to the winding roller 16 and is thereby wound up onto the winding roller 16 .
  • the prestressing achieved with the prestressing acts on the tension elements 52.
  • the winding motor 42 and the pulling motor 46 are designed in a correspondingly coordinated manner.
  • both motors 42, 46 are designed as electric motors that are controlled by a common switch.
