Definitions

  • This invention generally relates to rollable screens, such as sun protection screens. More specifically, the present invention relates to automating the rolling up and unrolling of these rollable screens.
  • a system for automatically rolling up the rollable screen can comprise a motor for rotating a rotatable tube for rolling up and unrolling the rollable screen, and a controller for controlling the motor.
  • the controller it is advantageous for the controller to have information about the position of the screen, for example whether it is rolled up or unrolled.
  • the motor can be turned off at the right time, for example when the screen is completely rolled up or unrolled, or when the screen has reached a certain desired position.
  • WO2019175573 and US2021071476 describe magnets that can be attached to the screen, for example on an underside of the screen.
  • a sensor such as a Hall sensor, can detect the magnets and thus determine the position of the unrollable screen.
  • EP2835490 and WO2014066158 also describe the use of magnets attached to the fabric. Because magnets are typically quite thick and can form protrusions on the fabric, such a system with magnets attached to the fabric is less suitable for flexible screens, such as rollable screens formed from a sunshade textile.
  • the present invention provides a system for automatically rolling up and unrolling a rollable screen.
  • the system comprises the rollable screen, comprising a magnetic field deforming structure.
  • the system further comprises a rotatable tube for rolling up and unrolling the rollable screen, and a motor for rotating the tube.
  • the system further comprises at least one coil assembly for generating a magnetic field and for detecting the generated magnetic field, arranged adjacent to a path along which the magnetic field deforming structure travels when the rollable screen is being rolled up and unrolled such that the magnetic field detected by the coil assembly is dependent on the rolled-up and unrolled position of the rollable screen.
  • the system further comprises a controller suitable for controlling the motor based on the magnetic field detected by the coil assembly.
  • each coil assembly comprises a transmitter coil for generating the magnetic field and a receiver coil for detecting the generated magnetic field, wherein the transmitter coil and the receiver coil are arranged on opposite sides of the path. It is an advantage of these embodiments that the automation of the rolling up and unrolling of a rollable screen can be relatively simple.
  • each coil assembly comprises a coil suitable for detecting the magnetic field generated by the coil itself. It is an advantage of these embodiments that only a single coil is required, which can make production of the system inexpensive and efficient.
  • the magnetic field deforming structure in a direction of rolling up or unrolling the rollable screen, comprises magnetic field deforming elements spaced at substantially equal distances from each other and separated from each other by areas substantially transparent to the magnetic field. It is an advantage of these embodiments that simple determination of the position, direction and speed of the rolling up and unrolling of the rollable screen can be achieved. Thus, moreover, it can be easily determined whether the rolling up or unrolling of the screen is blocked by an obstacle.
  • the invention is, however, not limited to these embodiments, and alternatively it is possible for the magnetic field deforming elements not to be spaced at equal distances.
  • the magnetic field deforming structure has the shape of a comb.
  • the magnetic field deforming elements are connected to each other (forming teeth of the comb fastened to a back of the comb), which allows them to be easily spaced at substantially equal distances from each other.
  • the back of the comb can be used to detect whether the beginning or end of the rollable screen has been reached, for example by providing a second coil assembly adjacent to a path along which the back of the comb travels when the rollable screen is being rolled up and unrolled.
  • the magnetic field deforming structure can, for example, variably deform the magnetic field along the path along which the magnetic field deforming structure travels when the rollable screen is being rolled up and unrolled.
  • a thickness of the magnetic field deforming structure varies along the path.
  • different materials, with different efficiency in deforming, e.g. blocking or reflecting a magnetic field are arranged along the path.
  • a width of the magnetic field deforming structure is varied along the path.
  • the magnetic field deforming structure comprises a film, a wire, an electrically conductive ink, a magnetic field blocking material such as graphite, a zip or a magnetically conductive material. It is an advantage of these embodiments that these structures can be easily attached to the screen.
  • the electrically conductive ink can be printed on the rollable screen, wherein the printed ink adheres to the screen. Electrically conductive or magnetic field blocking wire can be used to sew or stitch a pattern.
  • the magnetic field deforming structure has a thickness from 5 to 200 ⁇ m. It is an advantage of these embodiments that the magnetic field deforming structure can have a limited influence on the thickness of the rollable screen, and can also be rolled up on the rotatable tube.
  • the system comprises at least one side guide for receiving a side of the rollable screen so as to guide the rollable screen, wherein the magnetic field deforming structure is arranged on the side of the rollable screen, and wherein the at least one coil assembly is arranged in the side guide. It is an advantage of these embodiments that the magnetic field deforming structure and the coil assembly can be shielded from external influences, such as weather, flying materials, for example in case of wind, or touch.
  • the rollable screen contains a fabric, such as a sunshade textile, provided on at least one side with a zip for holding the fabric in the side guide, and wherein the magnetic field deforming structure is arranged between the fabric and the zip.
  • the zip typically comprises a zip textile, such as a strip of fabric or another material, fastened to the fabric, for example by stitching or welding such as ultrasonic welding or high-frequency welding, and zip teeth fastened to the zip textile, wherein the zip teeth are connected to the fabric via the zip textile.
  • the magnetic field deforming structure is arranged between the fabric and the zip textile of the zip. It is an advantage of these embodiments that the magnetic field deforming structure, e.g. film or wire, is well protected from possible damage by touch and when being rolled up on the tube.
  • the magnetic field deforming structure comprises a metal, preferably aluminium, copper or stainless steel. It is an advantage of these embodiments that the magnetic field deforming structure can be thin and still achieve good deformation, for example blocking, of the magnetic field.
  • the system is suitable for turning off the motor when the magnetic field detected by the coil assembly is substantially constant for a predetermined period of time. It is an advantage of these embodiments that it can be easily determined whether the screen is fully rolled up or fully unrolled, or blocked by an obstacle.
  • the rollable screen is typically used to block light that would enter through a window in the absence of the rollable screen, and is typically, when unrolled, parallel relative to the window.
  • the rollable screen comprises a fabric, preferably a sunshade textile.
  • the present invention is in particular suitable for sunshade textiles, such as screens, which are typically thin and flexible. It is a major advantage for the sunshade textile that the magnetic field deforming structure can also be thin and flexible.
  • the present invention provides a system for automatically rolling up and unrolling a rollable screen.
  • the system comprises the rollable screen, comprising a magnetic field deforming structure.
  • the system further comprises a rotatable tube for rolling up and unrolling the rollable screen, and a motor for rotating the tube.

  • the magnetic field deforming structure 3 has the shape of a comb, comprising a plurality of teeth 31 and a back 32 to which the teeth 31 are connected.
  • the teeth 31 form, in a direction of rolling up or unrolling the rollable screen 2, magnetic field deforming elements spaced at substantially equal distances from each other and separated from each other by areas 33 substantially transparent to magnetic fields.

  • the magnetic field deforming structure 3 can comprise, for example, a magnetic field blocking material, or a magnetic field absorbing material.
  • the magnetic field detected by the coil assembly 7 can be weaker if one of the teeth 31 is located at the coil assembly 7, than if one of the areas 33 substantially transparent to magnetic fields is located at the coil assembly 7. In this way, the magnetic field detected by the coil assembly 7 will become weaker (when a tooth 31 passes) and stronger (when a substantially transparent area 33 passes) during the rolling up or unrolling of the rollable screen.
  • the controller 6 can detect how often the detected magnetic field becomes alternately strong and weak, and on the basis thereof, in combination with information, for example from the motor 5, about the rotation direction of the motor 5 - that is, whether the motor 5 is rolling up or unrolling the rollable screen 2 -, and typically in combination with the known distance between consecutive teeth 31, determine the position of the rollable screen 2.
