Definitions

  • the invention relates to a method for manipulation with thermo-insulating a spa or swim spa cover between its closed position, open position and parking position, the thermo-insulating cover comprising a carrying thermo-insulating segment, coupled to an actuator, and a carried thermo-insulating segment, which is rotatably connected to the carrier segment, whereby the thermo-insulating cover is during opening or closing rotated by the carrier segment, which carries the carried segment and in the open position both thermo-insulating segments are in a vertical position facing each other with their bearing surfaces, whereby during opening and closing the carrier segment rotating about an axis which lies outside the ground plan of the spa or swim spa.
  • the invention also relates to a device for manipulation with a thermo-insulating spa or swim spa cover, which enables its automatic opening, closing and parking and which comprises a rotational device of a carrier segment for the rotation of the carrier segment between a closed position and an open position and a device for vertical manipulation with the cover between its open position and parking position.
  • spas or swim spas are used for relaxation and rehabilitation and they are also designed to complement houses and villas, both in the interior and the exterior.
  • Spas and swim spas range in ground plan size from approximately 1 x 2 m for a spa up to 3 x 6 m for a swim spa.
  • the structure of spas and swim spas is designed to keep the water clean and warm for a long time. This is achieved by an insulated structure of a shell and a thermo-insulating cover, which prevents leakage of moisture and heat from the spa or swim spa, thus reducing the operation costs.
  • thermo-insulating covers are made from a lightweight material, their weight is still relatively high with respect to their dimensions, which makes these covers difficult to handle.
  • the most commonly used thermo-insulating covers consist of two thermo-insulating segments, which are rotatably connected to each other and are manually moved from a closed position to an open position and vice versa. In the closed position, at the beginning of the handling operation one thermo-insulating segment is folded over the other, and so they touch each other with their originally upper sides, and subsequently they are removed, whereby two persons are usually necessary for the removal.
  • Another disadvantage of manual removal of the thermo-insulating cover is a problem of storing the thermo-insulating cover while the spa or swim spa is used.
  • thermo-insulating covers between their closed position and open position. Therefore, devices for manipulation with the segments of thermo-insulating covers between their closed position and open position have been developed, including both manually controlled mechanical devices and semiautomatic devices, as well as automatic devices reacting only to commands from an operator.
  • US5689841 discloses a mechanism for lifting a two-segment thermo-insulating cover from a spa or swim spa by means of a device with which is provided the first thermo-insulating segment, rotatably connected to the spa.
  • a device with which is provided the first thermo-insulating segment, rotatably connected to the spa.
  • the thermo-insulating cover When moving the thermo-insulating cover to a storage position, at first the second thermo-insulating segment is raised and folded back over the first thermo-insulating segment, and so both segments touch each other with their originally upper sides. After that the first thermo-insulating segment is raised to a vertical position along with the second thermo-insulating segment by means of a lifting device and, as a result, the spa is uncovered.
  • thermo-insulating cover remains on the edge of the spa in a vertical, i.e. storage position, in which it impedes access to the massage spa from one of its sides and restricts the view.
  • thermo-insulating cover in another position while the spa is used is partially solved, for example, by solutions disclosed in US7155756 , US5048153 , US5974600 or WO2007/058953 , in which the thermo-insulating cover, after being raised from the upper circumference of the spa, is lowered or dropped to a space outside the ground plan of the massage pool, for example, beside the back wall of the spa.
  • the weight of which is considerably high.
  • US7155756 discloses a mechanism for automatic folding of a second thermo-insulating segment over a first thermo-insulating segment to a position described in the above-mentioned solutions. This mechanism is rather complicated and puts great demands on the construction of the entire lifting device, which also increases its acquisition and operating costs. Moreover, the aesthetic impression is significantly worsened. All the devices for manipulation with thermo-insulating covers according to the background art must be dimensioned for lifting the entire weight of both thermo-insulating segments or for rotating the entire weight of both thermo-insulating segments, which means that these devices are bulky and their cost increases.
  • CZ PV 2008-243 discloses a method of manipulation with a thermo-insulating cover of a spa or a swim spa between its covering position and opened position.
  • the cover comprises a pair of thermo-insulating segments consisting of a carrier thermo-insulating segment and a carried thermo-insulating segment, which are rotatably connected to each other and in the covering position are lying with their bottom surfaces on the circumference of the spa or swim spa.
  • the carrier thermo-insulating segment is rotatably mounted on the spa or swim spa. During the phase of opening, the carrier thermo-insulating segment is rotated and its front end is raised, carrying the carried segment.
  • thermo-insulating spa or swim spa cover After the carrier segment reaches a vertical position, the carried segment is drawn by force to the carrier segment, until both segments touch each other with their bottom surfaces. In the opened position, therefore, the original upper sides of the segments are on the outside side of the raised pair of segments, which is advantageous compared to the previous solutions.
  • the method allows the thermo-insulating spa or swim spa cover to be opened and closed reliably, the operation of opening as well as closing is performed in two steps, each step requiring a separate device arranged on each side of the cover - two devices for the rotation of the carrier segment and two devices for bringing the carried segment closer and removing it, which increases costs and reduces reliability. Both segments can be lowered together to a storage position in a storage space, but two additional means for lowering and extending the thermo-insulating segments are needed.
  • the goal of the invention is achieved by a method according to the invention, whose principle consists in that prior to initiating rotation of the carrier thermo-insulating segment for opening, its axis of rotation is raised above its resting position to its upper position, thereby raising the rear face of the carrier segment and creating a gap between the bearing surface of the carrier segment and the edge of the spa vessel, whereupon the rotation of the carrier segment to a vertical position is initiated.
  • the inner surface of the spa or swim spa is connected by means of the gap to the surrounding environment and pressures are balanced, and so it is only the force derived by the weight of both segments of the thermo-insulating cover and any resistors that is overcome when rotating by means of the carrier segment. This reduces performance requirements of the rotational means.
  • thermo-insulating segments along with the rotational device After reaching the vertical position both thermo-insulating segments along with the rotational device are lowered to their parking position.
  • both thermo-insulating segments are displaced from the parking position to the opening/closing position in which both segments maintain the vertical position and the axis of rotation of the carrier segment is above the level of its resting position, whereupon the carrier segment rotates until the front portion thereof abuts the edge of the spa vessel, after which the axis of rotation of the carrier segment is moved to its resting position and both thermo-insulating segments are pressed against/put on the edge of the spa/swim spa.
  • the axis of rotation of the rotational device and the carrier segment is during both opening and closing in its upper position above its resting position, wherein the displacement of the axis of rotation of the rotation device and of the carrier segment between its resting position and the upper position is carried out in the vertical direction by a device for vertical manipulation with the carrier segment and the rotational device of the carrier segment.
  • the principle of the spa or swim spa cover manipulation device is that the carrier segment is fixedly attached to a rotational device which, in order to control its vertical position, is connected to a device for vertical manipulation with the cover and the rotational device, whereby it is vertically displaceable, together with the carrier segment, between its resting position, upper position and parking position.
  • the advantage of the device is its simple construction, reduced production costs, as well as lower maintenance costs due to improved reliability.
  • the device comprises a pair of rotary actuators mounted on the devices for vertical manipulation, which are coupled to struts of the frame of a control device, the rotational device and the device for vertical manipulation being coupled to a control unit which ensures the synchronization of pairs of rotary actuators and pairs of actuators of the devices for vertical manipulation, synchronizing both the initiation of their movement and the speed of this movement.
  • the rotational devices are hinged on flexible support members which are guided from the rotational devices upwards over carrying pulleys rotatably mounted on the frame of the control device above the upper position of the rotational devices and are further guided to a lifting and lowering actuator which is also mounted on the frame of the control device.
  • the rotational device of the carrier segment is mounted vertically on a movable beam of the device for vertical manipulation, whereby on the movable beam is mounted a swinging coulisse, which is coupled to a rotary actuator.
  • a swinging coulisse On the swinging coulisse are rotatably mounted rods coupled to angular levers arranged at the ends of the movable beam.
  • Each of the angular levers is coupled to a respective rotary lever, also swinging mounted on the movable beam on which a supporting plate is formed, which is fixedly attached to the rear face of the carrier segment.
  • the movable beam is hinged at two points at the ends of the flexible support member, which is guided from the point of the hinge upwards over the carrying pulleys rotatably mounted on the frame of the control unit above the upper position of the movable beam and is further guided to a lifting and lowering actuator, which is also mounted on frame of the control edevice.
  • the lifting and lowering actuator may be formed by a winding device rotatable in either direction, or by a linear actuator, whereby at the end of its movable portion is arranged a tightening member, to which is/are coupled a flexible support member/members.
  • the flexible support member in an embodiment with the movable beam being hinged it is advantageous for the flexible support member to have two branches, whereby the first branch is guided from the hinge on the movable beam over the first carrying pulley to a tightening member, which is wrapped by it, after which the first branch continues as a second branch, which is guided from the tightening member over an auxiliary pulley to a second carrying pulley, which is wrapped by it, and the second branch is terminated in the hinge on the movable beam, whereby the tightening member is mounted on a movable portion of the linear actuator, whose fixed portion is mounted in the frame of the control device, whereby the linear actuator constitutes a lifting and lowering actuator for vertical manipulation.
