Definitions

  • the invention relates to a protective roller blind for a building opening, with a covering sheet for at least partially covering the building opening, and with a roller blind box for receiving the covering sheet, and with two spaced apart and parallel profile strips as guide rails for a handle profile coupled to the covering sheet.
  • the invention further relates to an electromotive drive device for such a protective roller blind and a modular protective roller blind system for a building opening.
  • a protective roller blind In contrast to a pleated blind (Roman blind) in which a cover sheet is guided and held on bands, such a protective roller blind is wound on a shaft (roller shaft, winding shaft), which is usually rotatably mounted in a roller blind box.
  • the shaft interacts with a spring mechanism, for example, which is prestressed in the unwinding direction (pull-out direction) when the covering sheet is unrolled as intended.
  • Protective blinds of the type mentioned above are used to protect building openings, such as window or door openings (balcony or patio doors).
  • a protective roller blind is designed, for example, as a frame system with the roller blind box and two lateral guide profiles.
  • the covering membrane guided between the guide profiles or profile rails should cover the building opening as completely as possible.
  • the cover sheet prefferably be adjustable into a desired position by means of an electric drive device.
  • electric motor actuation is made possible with such protective roller blinds.
  • the drive device is often integrated in the roller blind box, the flexibility and adaptability of the protective roller blind being disadvantageously reduced by the integration of the drive device.
  • the adaptability to different opening sizes of the building opening is disadvantageously restricted.
  • the EP 0 911 479 A2 discloses a device for operating vertical flexible doors having a roll-up tube internally provided with means for inserting a geared motor and a spring-loaded compensating member, the tube being provided with means for connection to a coupling member and means for quick connection of a cover sheet.
  • a method for manual and/or remote control of a motorized roller shutter which comprises a roller shutter fixed to a roller shutter tube, a DC geared motor arranged in the roller shutter tube and a microcontroller.
  • the invention is based on the object of specifying a particularly suitable protective roller blind for a building opening.
  • a protective roller blind with an electromotive drive device is to be specified, which can be adapted as flexibly as possible to different building openings and general conditions.
  • the invention is also based on the object of specifying a particularly suitable electromotive drive device for such a protective roller blind and a particularly suitable protective roller blind modular system with such a protective roller blind.
  • the object is achieved according to the invention with the features of claim 1 and with regard to the drive device with the features of claim 8 and with regard to the protective roller blind modular system with the features of claim 10 .
  • Advantageous refinements and developments are the subject of the dependent claims.
  • the advantages and configurations listed with regard to the protective roller blind can also be transferred to the drive device and/or the protective roller blind modular system and vice versa.
  • the protective roller blind according to the invention is suitable and set up for installation in a building opening, in particular in a window opening or a door opening.
  • the protective roller blind has a covering sheet in the form of a roller blind cloth or roller blind fabric, by means of which the building opening can be at least partially covered.
  • the cover sheet is preferably designed as a protective fabric, in particular as a particle, insect or pollen protection fabric, or as a visual or sun protection fabric.
  • the cover sheet is designed in particular as a mesh fabric (insect protection mesh).
  • the covering web is preferably designed to be optically non-transparent or non-transparent.
  • the protective roller blind also has a roller blind box or a roller blind cassette for accommodating the covering sheet.
  • the cover sheet it is possible for the cover sheet to be arranged essentially completely in the roller blind case for an opening of the protective roller blind or the building opening. As a result, the covering membrane is reliably protected from external influences.
  • the protective roller blind has two mutually spaced and parallel profile strips as guide rails for a handle profile (end strip, pull-out strip) coupled to the cover sheet.
  • the profile strips and the roller blind box here form a mountable or mounted frame system of the protective blinds.
  • the profile strips are arranged as vertical longitudinal profiles on the sides of the building opening, i.e. on the reveal or frame, with the roller blind box being arranged as a horizontal transverse profile on an upper edge of the building opening, i.e. in the area of the lintel.
  • the roller blind box has an open (longitudinal) slot in the mounted state, ie facing the profile strips or the ground, via which the covering sheet with the handle profile can be pulled out manually along the guide of the profile strips.
  • the protective roller blind according to the invention also has an electromotive drive device which is integrated in the roller blind box, ie is installed in the roller blind box.
  • the electrical or electromotive drive device is suitable and set up to adjust the covering web along an unwinding direction or pull-out direction, which is essentially oriented along the profile strips.
  • the approximately cylindrical drive device has an electromotive tubular motor and a spring shaft as well as a hollow shaft that can be lengthened (hollow winding shaft).
  • the hollow shaft is provided with an inner contour in which the tubular motor and the spring shaft, designed for example as a helical spring, each engage with a counter-contour.
  • the tubular motor and the spring shaft engage in the hollow shaft from opposite end faces in a form-fitting and non-rotatable manner.
  • the hollow shaft is rotatably or rotatably mounted by means of the spring shaft and the tubular motor.
  • a "positive fit” or a "positive connection” between at least two parts connected to one another is understood here and in the following in particular to mean that the parts connected to one another are held together at least in one direction by direct interlocking of the contours of the parts themselves or by indirect interlocking about a additional connecting part takes place.
  • the "blocking" of a mutual movement in this direction is therefore due to the shape.
  • the protective roller blind or the drive device can be individually adapted to different window or door dimensions, so that the protective roller blind can be flexibly mounted on or in practically all common building openings.
  • the roller blind box and the cover strip are also designed so that they can be cut to length.
  • the design with the tubular motor and spring shaft inserted, pushed or plugged into the hollow shaft results in a structurally simple drive device that can be cut to length. Since the tubular motor and the spring shaft are used on opposite end faces of the hollow shaft, the counter-contours within the hollow shaft are essentially spatially spaced apart from one another, ie a hollow or intermediate space is formed between the counter-contours. The tubular motor and the spring shaft are thus coupled to one another only indirectly via the hollow shaft. This makes it possible to dimension or change the overall length of the drive device by means of a comparatively simple and cost-reduced lengthening of the hollow shaft.
  • the counter-contour of the tubular motor is expediently coupled to its rotor in a rotationally fixed manner, so that when the rotor rotates, the hollow shaft—and thus the spring shaft—are rotated.
  • the inner contour and the counter-contours are thus designed as joining contours that engage in one another in a form-fitting and non-rotatable manner.
  • the tubular motor and the spring shaft are coupled in terms of drive technology by means of the hollow shaft.
  • the quality of the cut edges during the cutting to length of the hollow shaft is not critical. This further improves the flexibility of the protective blind.
  • the approximately cylindrical or bolt-shaped tubular motor has an axial size that is larger than its radial size.
  • the tubular motor has a comparatively low (radial) axis height and a comparatively long (axial) overall length, in particular the overall length is many times greater than the axis height.
  • the spring shaft and the tubular motor are seated essentially completely in the hollow shaft when they are joined or assembled. In other words, the spring shaft and the tubular motor are essentially fully inserted or pushed into the hollow shaft at the opposite end faces.
  • the hollow-cylindrical or tubular hollow shaft extends essentially over the full (horizontal) length of the roller blind box.
  • the tubular motor, the spring shaft and the hollow shaft are arranged coaxially to one another.
  • the spring shaft is preferably embodied as a spring mechanism which is mechanically pretensioned when the covering web is unrolled or unwound along the unwinding direction.
  • the tubular motor suitably has a static holding moment, which holds the cover web in the unwound state against the pretension.
  • the tubular motor acts as a blocking or arresting and/or braking means, which prevents an unintentional, abrupt hitting or winding up of the covering web due to spring force-induced rolling up. This means that essentially no additional locking or blocking means are provided for the drive device.
  • the spring mechanism supports the tubular motor when the covering sheet is rolled up. As a result, the tubular motor can be dimensioned comparatively small with regard to the torque required, and is therefore particularly cost-effective.
  • the drive device To actuate the drive device or the tubular motor, it is possible, for example, for the drive device to have a transceiver for sending and receiving wireless signals. This makes it possible, for example, to couple the drive device to an operating element, such as a radio remote control, and by means of this easy to operate. This significantly improves the user comfort of the protective roller blind.
  • the operating element can also be designed, for example, as a mobile phone, in particular as a mobile phone with a computer function or as a smartphone, or also as a tablet computer.
  • the operating element has, for example, stored application software (operating software) for controlling the drive device.
  • the application software application software
  • the application software can preferably be installed or installed on the control element as a so-called app or mobile app (mobile application, smartphone app).
  • the tubular motor has a shorter overall axial length than the spring shaft in relation to a longitudinal direction of the hollow shaft (axial direction). As a result, a particularly space-compact tubular motor is realized.
  • the drive device has a chargeable electrical energy store, for example in the form of an electrochemical accumulator, which is coupled to the tubular motor.
  • the energy store is integrated in the roller blind box, in particular in the tubular motor. This further improves the flexibility of the protective roller blind, since the drive device can thus be operated essentially independently of a supply network. In other words, no additional mains connection of the drive device is necessary.
  • the energy store can be charged by means of a photovoltaic or solar cell, or a photovoltaic or solar panel.
  • the photovoltaic cell is expediently arranged on a surface of the roller blind box facing the outside of the building. This enables the energy store to be charged in a particularly cost-effective manner and with reduced effort.
  • the energy store integrated in particular in the tubular motor expediently has a charging interface for electrically conductive coupling to the photovoltaic cell.
  • the charging interface is designed as a USB-C socket, for example, so that the energy storage device can also be connected to a mobile auxiliary battery (power bank) for charging, if required, for example when it is cloudy.
  • power bank mobile auxiliary battery
  • the counter-contour of the spring shaft and/or the tubular motor has a driver head with radial ribs distributed in the circumferential direction, which in the assembled state lie against the inner wall side, for example with a force fit or friction fit, in the inner contour.
  • the driver head of the counter-contour is thus connected to the hollow shaft on the inner wall side in a form-fitting manner, practically fixed to the latter. This ensures a particularly stable and non-rotatable drive coupling of the spring shaft and/or the tubular motor to the hollow shaft.
  • a “positive connection” or a “positive connection” between at least two parts connected to one another is understood here and in the following in particular to mean that the parts connected to one another are prevented from sliding off one another due to a frictional force acting between them. If there is no "connection force” that causes this frictional force (this means the force that presses the parts against one another, for example a screw force or the force of weight itself), the non-positive connection cannot be maintained and can therefore be released.
  • the roller blind box has a cover cap on each of its opposite end faces.
  • the lateral cut edges of the roller blind box which can preferably be cut to length, can thus be covered in a visually attractive manner by means of the covering cap.
  • the cover caps are each with one along the longitudinal direction the hollow shaft is provided with an axially projecting joining contour, by means of which the spring shaft or the tubular motor is held in the roller blind box in a stationary or non-rotatable manner.
  • the joining contour for the spring shaft is designed as an axial journal, onto which the spring shaft is placed in a non-positive or frictional manner.
  • a rotatably mounted shaft bushing for the hollow shaft is arranged on the spring shaft in the area of the axial journal.
  • the joining contour for the tubular motor is designed as an axial joining pin, which engages in a form-fitting manner in a joining receptacle of the tubular motor. This ensures a simple and reliable stationary and non-rotatable mounting of the tubular motor in the roller blind box.
  • the electromotive drive device is suitable and set up for a protective roller blind as described above.
  • the drive device has an electric or electromotive tubular motor and a spring shaft as well as a hollow shaft that couples these to one another in terms of drive technology.
  • the hollow shaft can be cut to length and is provided with an inner contour in which the tubular motor and the spring shaft engage in a form-fitting and non-rotatable manner by means of counter-contours on opposite end faces of the hollow shaft.
  • the protective roller blind modular system is provided as an assembly set according to the modular principle, in particular as a DIY assembly set (do-it-yourself), for individual adjustment to different window or door dimensions, so that the system can be flexibly adapted to practically all common building openings.
  • roller blind box and the drive device as well as the profile strips and the covering sheet are each manufactured in just one or in as few different standard sizes as possible, and a consumer can put together an individual protective roller blind or frame system for the respective building opening.
  • the flexibility of the protective roller blind that can be mounted as a result is increased in a simple and advantageous manner and thus an adaptation to different boundary conditions for the mounting found on site is made possible.
  • the roller blind box, the drive device or the hollow shaft, the profiled strips, the handle profile, and the covering sheet are designed to be cut to length. This further increases the flexibility of the protective roller blind modular system and, for example, simplifies its use in old buildings with variable opening dimensions.
  • the cut edges of the roller blind box can preferably be covered in a visually attractive manner by means of a cover cap that can be placed on the front side.
  • the profile strips also have, for example, a covering cap on the substrate side in the assembled state in the form of a base for covering the cut edges.
  • the profile strips and the roller blind box as well as the handle profile are preferably metal profiles that can be cut to length, for example made of aluminum. Their cross section is preferably essentially rectangular. However, square or rounded designs are also conceivable.
  • the 1 shows a front view of a protective roller blind 2 with a roller blind box 4 and profile strips 6 arranged laterally thereon.
  • the covering sheet 10 is held on the one hand at the web end on the handle profile 8, for example by means of a welt, and on the other hand at the web end is wound onto a hollow shaft (winding shaft, roller blind shaft) 12 that can be cut to length ( 3 ).
  • the profile strips 6 can be screwed to a reveal or frame of a building opening by means of three fastening elements 14 each.
  • the cover sheet 10 is, for example, a particle, insect or pollen protection fabric (insect screen).
  • the cover strip 10 can also be a visual or sun protection fabric or the like.

  • the spring shaft 32 is designed as a spring mechanism which, when the cover sheet 10 is unwound manually or by an electric motor along a vertical unwinding direction (pull-out direction) A from the hollow shaft 12, prestresses the latter and thus the cover sheet 10 in the opposite direction or in the winding direction (pull-in direction) B in a spring-elastic manner.
