Cover for a swimming pool or whirlpool bath and swimming pool or whirlpool bath that is provided therewith
Cover for a swimming pool or whirlpool bath, whereby the cover includes a rollup screen whereby the screen has two side edges and whereby the screen has a first edge perpendicular to the side edges and a second edge perpendicular to the side edges, whereby the cover includes a rollup shaft, whereby the first edge of the screen is connected to the rollup shaft and whereby the screen can be rolled up and rolled out on the rollup shaft, whereby the rollup shaft is horizontally movable so that the screen can be rolled out while the second edge is in a fixed position and whereby the cover is provided with a unit to exert a rotational force on the rollup shaft to thereby roll up the screen.
1. A cover for a swimming pool or whirlpool bath, the cover comprising:
a rollup screen made of lamellae located next to one another and connected together with a hinge, the screen having two side edges formed by ends of the lamellae, the screen having a first edge perpendicular to the side edges and a second edge perpendicular to the side edges;
a rollup shaft, the first edge of the rollup screen being connected to the rollup shaft, the screen being configured to be rolled up and rolled out on the rollup shaft, the rollup shaft being horizontally movable so that the screen is configured to be rolled out while the second edge is in a fixed position; and
a drive configured to exert a rotational force on the rollup shaft to thereby roll up the screen,
wherein, during a rollup movement or rollout movement, the rollup shaft rests on the entirely or partially rolled-up screen and is thereby supported by the rolled-up screen, and
the lamellae are connected together so that in use when resting in a flat position on a surface to be covered, the lamellae are configured to only hinge upwards in a direction away from the surface to the covered.
2. The cover according to claim 1 , wherein the drive is formed by an electric motor with a rotor to drive the rollup shaft and a stator, the stator being connected via a first arm to a first support that is affixed to one of the side edges of the screen and which is movable over the one side edge.
3. The cover according to claim 2 , wherein the rotor is connected in a rotational force-transmitting way to the rollup shaft in order to drive the rollup shaft during a rollup movement in which the stator is not rotatable with respect to the first support, the first support being affixed around the one side edge of the screen.
4. The cover according to claim 2 , wherein the first support is at least partially under the one side edge so that the first support is blocked by the one side edge in relation to an upward movement.
5. The cover according to claim 2 , wherein the first support is only connected to components of the cover.
6. The cover according to claim 2 , wherein the cover does not comprise a rigid linear guide for guiding a horizontal movement of the first support.
7. The cover according to claim 2 , wherein the rollup shaft is hollow and the electric motor is affixed in the rollup shaft.
8. The cover according to claim 1 , wherein the rollup shaft is connected via a second arm to a second support that is affixed to one of the side edges of the screen and which is movable over the one side edge by at least one wheel that is affixed to the second support and which grips on the one side edge of the screen and which is driven in the direction from the second edge to the first edge.
9. The cover according to claim 8 , wherein the at least one wheel is driven by the rotor of the electric motor, the electric motor being provided with a switched coupling to thereby alternately drive the rollup tube or the at least one wheel, depending on the direction of rotation of the rotor.
10. The cover according to claim 1 , wherein the lamellae have a curve so that in the rolled out position, the screen has a downward incline towards the side edges with an average angle between 0.5° and 3°, whereby the lamellae are sufficiently elastically deformable to be brought to a straight position under tension.
11. The cover according to claim 1 , wherein the lamellae have a curve due to having lamella bodies that are made of plastic in which fibers are affixed under tension in the longitudinal direction of the lamella bodies, and
the average tension in the fibers on the underside of the lamella bodies is greater than in the fibers on the top of the lamella bodies.
12. The cover according to claim 1 , wherein the lamellae are provided on their underside with a thermally conductive layer that extends over at least a section of the longitudinal direction of the lamellae.
13. The cover according to claim 1 , wherein the underside of the lamellae are made of a soft deformable plastic.
14. The cover according to claim 1 , wherein the lamellae are coupled together by a coupling of flexible plastic, the lamellae having a maximum width at a position lower than the coupling.
15. The cover according to claim 1 , wherein, in use in relation to the swimming pool or the whirlpool bath, the lamellae of a rolled-up portion of the screen rests on side edges of the swimming pool or the whirlpool bath.
16. A whirlpool system, comprising:
a whirlpool bath having edges; and
the cover according to claim 1 provided at the whirlpool bath, the cover being mounted such that the rollup shaft is horizontally moveable to be able to roll up or roll out the screen along the edges of the whirlpool bath through a horizontal movement of the rollup shaft, while the second edge of the screen is held at a fixed position.
17. The whirlpool system according to claim 16 , wherein the whirlpool bath is not provided with a rail or other guide for guiding a rollup movement and/or rollout movement of the cover, which, independently of the rollup position of the cover, extends parallel to the two side edges.
18. The whirlpool system according to claim 16 , wherein the drive is formed by an electric motor with a rotor to drive the rollup shaft and a stator, the stator being connected via a first arm to a first support that is affixed to one of the side edges of the screen and which is movable over the one side edge, the rotor being connected in a rotational force-transmitting way to the rollup shaft in order to drive the rollup shaft during a rollup movement whereby the stator is not rotatable with respect to the first support, the first support being affixed around the one side edge of the screen, wherein a first component of a closure is fastened on the first or the second support or the first or second arm, a second component of the closure being fastened to the whirlpool bath, the closure being configured to block a vertical movement of the first component with respect to the second component due to the first component being able to be introduced horizontally in or around or below the second component.
