Definitions
- Rolling tube system and shielding system comprising such a rolling tube system
- the invention relates to a rolling tube system for rolling up and unrolling for instance a sunblind, a roll-down shutter, a rolling door and the like, comprising a hollow rolling tube having therein a drive comprising an electric motor and an output shaft .
- a sunblind, a roll-down shutter, a rolling door and the like are embodiments of a roll-up screen.
- Such rolling tube systems are for instance known for sunblinds, roll-down shutters and rolling doors.
- the known rolling tube system is usually situated in a housing fixedly mounted on the outer wall of a building. Wound for instance round the tube is a sunblind which can be lowered by rolling the rolling tube and which can, if necessary, also be rolled back onto the tube.
- the output shaft of the electric motor in the tube usually forms the input shaft of a reducing device which is coupled to a catch.
- the catch drives the tube.
- the tube is provided with a keder groove in which the sunblind is attached with a keder or a string. The inner side of the keder groove provides an internal protrusion inside the tube.
- the known rolling tube systems have a number of drawbacks.
- the rolling tube thus rotates round the electric motor and has to run freely relative thereto. This limits the size of the electric motor, all the more so in that the protrusion formed on the inner side by the keder groove further limits the possible space for an electric motor.
- the keder groove is omitted at the position of the motor, this local omission entails extra costs for the construction of the tube and for fitting of the web, while it is still not possible to utilize the whole inner space of the tube. Because the electric motor remains clear of the outer surface and is further enclosed in the tube, there is practically no heat discharge from the electric motor, whereby it can only operate continuously for a very limited time.
- the present invention has for its object to provide a rolling tube system wherein the above stated drawbacks do not occur, or hardly so. This object is achieved with the rolling tube system according to claims 1 and 22 and the screening system according to claim 16.
- a reducing unit can also be incorporated in the drive according to the invention.
- An output shaft of the electric motor forms here the input shaft of the reducing unit and the output shaft of the reducing unit is the output shaft of the drive.
- An external surface of the reducing unit has to be coupled to the internal surface of the rolling tube.
- the rolling tube When heavier loads will be rolled up and unrolled in a substantially vertical direction with the rolling tube system, it is advantageous to arrange in the rolling tube a torsion spring which is attached at an outer end to the rolling tube and another outer end of which is fixedly coupled to a second stationary element, preferably in the form of a guide, situated outside the tube such that rotation of this other outer end relative to the second stationary element is prevented.
- a second stationary element preferably in the form of a guide
- the couplings of both the output shaft and the torsion spring to respectively the first stationary element and the second stationary element can be a fixed connection to the relevant stationary element.
- a fixed connection can be a random fixed connection, such as by means of screwing, welding and the like.
- the rolling tube system according to the invention can be used particularly in installations in which a rolling tube co-displaces with the rolling up and unrolling and therein rolls itself up in or unrolls itself from for instance the web of a sunblind along a rolling direction.
- a rolling tube can be arranged at the outer end to be unrolled or lowered, or for instance in the centre of a sunblind, so that when the sunblind is unrolled the rolling tube also moves downward and when it is rolled up the rolling tube co-displaces upward.
- the first and the second stationary element form a guide with a substantially U-shaped profile, wherein the longitudinal direction of the guide lies at a right angle to an axis of the output shaft or of the torsion spring, and the output shaft or the torsion spring is preferably provided at an outer end with an elongate end part movable in the longitudinal direction inside the U-shape of the associated stationary element. Because these elongate end parts move inside the U-shape of the associated stationary element, this U-shape prevents rotation of the elongate end parts, and thereby rotation of the torsion spring and of the output shaft of the drive. The elongate end parts slide along with the moving rolling tube inside the U-shape.
- the friction between the elongate end part and one of the legs of the U-shaped guide may become considerable.
- the elongate end part is advantageous for the elongate end part to be provided with at least a roll for rolling movement along at least one of the legs of the U-shape.
- a sliding movement is hereby replaced with a rolling movement, which in principle results in less friction.
- the hollow rolling tube is provided with coupling means for coupling to said roll-up screen.
- the hollow rolling tube can further have an electrical connection which is electrically connected to the electric motor, and preferably to the stator of the electric motor. This electrical connection can be coupled to or integrated into the coupling means and/or be placed fixedly on an outer surface of the rolling tube.
- the rolling tube system comprises a rolling tube provided with at least a keder groove for the purpose of attaching therein the sunblind, the roll-down shutter or rolling door and the like, and the keder groove forms an internal protrusion on the inner side of the rolling tube, there is arranged in the outer periphery of the stator of the electric motor a groove which enters into the engagement with said protrusion. Together with the fitting groove in the outer periphery of the stator of the electric motor this protrusion forms here the coupling of the stator of the electric motor to the hollow rolling tube.
- the rolling tube system it is further not necessary to interrupt the keder groove at the position of the tube motor, which saves costs of the rolling tube and assembly of the system.
- a passage can also be made at the position of the keder groove for the purpose of realizing an electrical connection for external power supply to the electric motor.
- the rolling tube of the rolling tube system according to the invention is situated halfway along or on a determined part of the blind, shutter and the like to be rolled up and unrolled
- the rolling tube can be provided with second keder grooves, the two internal protrusions of which engage in the associated groove in the stator of the electric motor .
- the electric motor is advantageous for the electric motor to be fed by a power supply situated in the rolling tube, wherein the power supply comprises at least a battery.
- the power supply in the rolling tube will also comprise a converter in addition to a battery.
- the system is also provided with a control situated in the rolling tube and sensors connected to the control .
- sensors can for instance be rotation measuring devices or power measuring devices, for instance for the purpose of measuring the number of rotations and/or for the purpose of measuring the power consumed.
- control can be programmed using a remote control. It is hereby possible to determine for instance the number of rotations the rolling tube must roll in a determined direction. It is hereby also possible to set for instance the maximum time for which the rolling tube may roll in a determined direction .
- the system in which a power supply is situated inside the rolling tube, it is advantageous for the system to be provided with a charging device, a part of which is situated inside a rolling tube and another part of which is situated at a stationary position outside the rolling tube, wherein these parts are coupled electrically or electromagnetically when the rolling tube is in a predetermined position, this position being set in the control .
- the battery can hereby be charged in the rolling tube, for instance by placing the charging device at fixed preferred positions, such as the rolled-up position or the unrolled position, or both.
- the part of the charging device situated outside the rolling tube can be coupled electrically to the part situated inside the rolling tube, for instance in that the rolling tube is provided on the outer side with contacts which make contact in this position with contacts of the external part of the charging device. It is also possible for the charging to take place through induction. It must however be ensured for this purpose that, when the rolling tube is in a charging position, it is not provided at the appropriate locations with a continuous metal sleeve, but that electromagnetic openings are arranged in the rolling tube for this purpose. These openings can of course be formed by a plastic with suitable electromagnetic properties. It is also possible to envisage a rolling tube system wherein the two end parts lie in the same stationary element or wherein the two end parts are also the same.
- the present invention also provides a screening system as defined in claim 16.
- This system comprises an embodiment of the above described rolling tube system coupled to a roll-up screen.
- the screening system comprises an electrical power supply unit and an electrical connection, such as an electrical cable or cord, for the purpose of electrically connecting the electrical power supply unit to the electrical connection of the hollow tube.
- the electrical connection is connected fixedly to the roll-up screen and/or is at least partially integrated in the roll-up screen.
- This embodiment provides the advantage that the electrical connection is rolled up together with the roll-up screen. In such embodiments there is thus no, or hardly any, danger of the electrical connection becoming tangled during translation of the rolling tube.
- the electrical power supply unit is formed by solar panels mounted on the roll-up screen or integrated therein. Such solar panels can be used to charge a battery optionally present in the rolling tube.
