Definitions

  • the invention relates to a screen door operating device for automatically opening and closing a screen door, the screen door comprising an elongate insect screen holder for a rolled or concertina folded insect screen that with an edged is attached to an elongate, movable and in operation vertically oriented closing strip which is parallel to the elongate insect screen holder and is movable between an open position in which the insect screen is rolled up or folded and a closed position in which the insect screen is unrolled or unfolded.
  • An object of the invention is to provide a screen door operating device which is relatively inexpensive.
  • the screen door operating device according to the invention is characterized in that it comprises:
  • the screen door operating device according to the invention can be applied to existing screen doors. This means that existing production processes for screen doors do not have to be adapted. Only an operating device has to be produced that has to be fitted around an already existing screen door.
  • An elongated, flexible, upper drive element can be a cord or string.
  • cord or belt drives protection against overload is obtained by limiting the maximum force due to the rope or belt slipping over a wheel.
  • An embodiment of the screen door operating device in which the lower and upper drive elements can be moved well, is characterized in that the drive further comprises a central drive element which is wrapped around a drive wheel connected to the drive motor, from which drive wheel two parallel branches of the middle drive element extend, wherein the upper and lower drive elements with their ends are attached to both branches of the middle drive element.
  • An embodiment of the screen door operating device according to the invention, in which the drivers can be moved simultaneously, is characterized in that:
  • the middle drive element is endless and, in addition to said drive wheel, is wrapped around a further wheel which is located at a vertical distance from the drive wheel.
  • a further embodiment of the screen door operating device is characterized in that next to each branch of the middle drive element there is a further switch which is operated by a coupling piece by which the drive elements are attached to the middle drive element for switching off the drive motor in the extreme positions of the vertical closing strip in which the screen door is fully open or closed.
  • Another embodiment for stopping the closing strip automatically and being able to set the extreme position of the closing strip is characterized in that a sensor for switching off the drive motor is present next to each branch of the third drive element in the extreme positions of the vertical closing strip in which the screen door is fully open or closed.
  • a further embodiment of the screen door operating device is characterized in that the drive motor is movable along a vertical guide and the switch is designed as a push button and when pressed activates the drive motor to move the drivers, which push button can also be turned and when turned moves the drive motor along the vertical guide thereby disengaging the drive motor from the driven drive wheel. Because the drive motor can be easily disconnected, the screen door can be easily operated manually. By integrating many functions into the rotary knob, few switches are required to control the drive.
  • Another embodiment in which the drive motor can be easily disconnected is characterized in that the switch when turned moves an operating rod which displaces the drive motor and thereby disengages a gear wheel present on an output shaft of the drive motor from engagement with a further gear of the transmission coupled to the drive wheel, so that the drive motor can be disengaged from the drive wheel and the drive wheel can rotate freely.
  • a further embodiment of the screen door operating device is characterized in that the drive motor is provided on a carriage which can be moved downwards against a spring force and that a safety switch is provided below and spaced from the carriage, which switch, when activated, causes the drive motor to rotate in the direction for opening the screen door, so that when the closing strip is blocked during closing of the screen door, the drive motor pulls itself and the associated carriage downwards and activates the safety switch.
  • Yet another embodiment of the screen door operating device is characterized in that it comprises a control unit which, after displacing the drivers for opening the screen door, after a preset time, moves the drivers back to the position where the screen door is closed.
  • Yet another embodiment of the screen door operating device according to the invention is characterized in that the switch is incorporated in the closing strip, such that the switch is actuated by tapping the closing strip.
  • the invention also relates to an automatic screen door device comprising a screen door that includes:
  • FIGS 1-3 show an embodiment of the screen door operating device according to the invention.
  • the screen door operating device 1 has a vertical tube 3, an upper guide profile 5 which, at a first end 5A, is connected with the vertical tube 3, and a lower guide profile 7 which, at a first end 7A, is coupled with the vertical tube 3.
  • the vertical tube 3 and the lower and upper guide profiles 5 and 7 can be coupled to a screen door 101 which is indicated in broken lines in figure 1 .
  • the screen door has an elongate insect screen holder which is designed as a cassette 103 which can be coupled to the vertical tube 3.
  • an insect screen 105 is folded in concertina shape, which is attached with one edge to a vertical closing strip 107 which is parallel to the elongate cassette 103 and which is displaceable with an upper end 107A in the upper guide profile 5 and with a lower end 107B in the lower guide profile 7 while pulling the insect screen 105 out of the cassette 103 or pushing it into the cassette.
  • Two drivers 9 and 11 can be moved in the upper and lower guide profile 5 and 7, which drivers can be coupled to the vertical closing strip 107 of the screen door.
  • a drive 13 is present in the vertical tube 3 and in the lower and upper guide profiles 5 and 7 for displacing the drivers 9 and 11. This drive 13 is operated by a switch 15 present on the vertical tube 3.
  • the screen door 101 has also a lower guide 109 over which the vertical closing strip 107 runs and an upper guide 111 in which the vertical closing strip 107 is movable. These guides must be omitted when coupling the screen door 101 with the screen door operating device 1 and should be replaced by the lower and upper guide profiles 5 and 7 of the screen door operating device 1.
  • the drive 13 has a drive motor 22 which is present in the vertical tube 3 and which drives a belt drive wheel 19 via a gear transmission (of which gear 24 is part, among other things).
  • An endless central drive element, in the form of a drive belt 17, is wrapped around this belt drive wheel 19 and a further belt wheel 20.
  • the two belt wheels 19 and 20 are located in the vertical tube 3 at a vertical distance from each other.
  • Two parallel branches 17A and 17B of the drive belt 17 extend between the belt wheels 19 and 20.
  • the drive 13 furthermore has an upper drive element, designed as a drive cord 21, which is connected at both ends to the drive belt 17 and which is wrapped via two upper guide rollers 25 present in the top of the vertical tube 3 around an upper cord guide wheel 23 which is located near a second end 5B of the lintel.
  • This upper drive cord 17 is connected to the drive belt 17 with a first end 21c at the location of the first branch 17A and is connected to the drive belt 17 with a second end 21d at the location of the second branch 17B.
  • the upper guide rollers 25 guide the upper drive cord 90 degrees from vertical to horizontal direction and vice versa.
  • the drive 13 is provided with a lower drive element, also designed as a drive cord 27, which is also connected to the drive belt at both ends, a first end 27c of the lower drive cord being connected to the drive belt 17 at the location of the first branch 17A and a second end 27d of the lower drive cord is connected to the drive belt 17 at the second branch 17B.
  • the lower drive cord 27 is wrapped around a lower cord guide wheel 29 which is present near a second end 7B of the lower guide profile and is guided by two lower guide rollers 31 present in the bottom of the vertical tube 3 from vertical to horizontal direction and vice versa.
  • the lower driver 11 is connected to the first branch 27A of the lower drive cord 27 and the upper driver 9 is connected to the second branch 21B of the upper drive cord 21. Due to this construction, when the drive belt 17 is driven, the two drivers 9 and 11 move simultaneously and in the same direction (away from or towards the vertical tube).
  • the drive motor 22 in the vertical tube 3 can be moved along a vertical guide 33 in the vertical tube 3.
  • the switch 15 is designed as a rotary knob which can also be pressed. Depressing the rotary knob activates the drive motor 22 which moves the drivers 9 and 11 towards the vertical tube 3, thereby opening the screen door. After some time, a control unit 43 activates the drive motor 22 to move the drivers 9 and 11 back to the position in which the screen door 101 is closed.
  • the drive motor 22 When the rotary knob is turned, the drive motor 22 is pressed upwards over the guide 33 via an arm 16 attached to the rotary knob and a connecting rod 18 present between the end of this arm and the drive motor, whereby a gear 24 connected to the drive motor 22 is released of a sprocket connected to the upper belt guide wheel 19, so that the drive belt 17 can no longer be driven by the drive motor 22.
  • the power supply to the drive motor 22 is also interrupted.
  • a switch 35 and 37 Adjacent to each branch 17A and 17B of the drive belt 17 is a switch 35 and 37, respectively, for turning off the drive motor 22. These switches are depressed by coupling pieces 39 and 41, connecting the lower and upper drive cords 21 and 27 to the drive belt 17, when they come into contact with the switches during drive of the drive belt 17.
  • the positions of the switches 35 and 37 along the drive belt determine the extreme positions of the drivers and thus the extreme positions of the vertical closing strip 107 (fully open against the vertical tube 3 or completely closed at the location of the second ends 5B and 7B of the upper and lower guide profiles.
  • FIG. 4 shows an embodiment of the automatic screen door device according to the invention.
  • the screen door has a vertical insect screen holder 103 which is to be placed vertically in a passage against a wall bounding the passage.
  • a concertina-shaped folded insect screen 105 is attached with a vertical edge to the vertical insect screen holder 103 (not visible in the figure).
  • a horizontally extending upper guide profile 5 and lower guide profile 7, respectively, are connected to the vertical insect screen holder 103.
  • the insect screen 105 is attached to an elongate, movable vertical closing strip 107 with an opposite vertical edge.
  • the vertical closing strip 107 is movable along the guide profiles 5 and 7 and thereby unfolds or folds the insect screen.
  • an operating device 1 for moving the vertical closing strip 107 along the guide profiles.
  • the operating device 1 is shown enlarged.
  • This operating device 1 consists of a drive 13 and a switch 15 for operating the drive.
  • the vertical closing strip 107 is connected to an upper driver 9, which is displaceable along the upper guide profile 5, and a lower driver 11, which is displaceable along the lower guide profile 7.
  • the drive 13 will move the drivers 9 and 11 and thereby open and close the screen door.
  • the drive 13 has an elongate, flexible, central drive element 17, which is formed by a ball chain which is wrapped through 180 degrees around a drive wheel 19 present in the vertical insect screen holder 103.
  • Two parallel branches 17A and 17B of the middle drive element 17 extend from the drive wheel 19.
  • a drive motor 22 which is coupled to the drive wheel 19 is further provided against the vertical insect screen holder 103.
  • the drive 13 further has an elongate, flexible, lower drive element 27, which is formed by a cord connected at both ends to the ends of the middle drive element 17.
  • a first end 27c of the lower drive element is connected via a first coupling piece 39 with a first branch 17A of the middle drive element 17 and a second end 27d of the lower drive element is connected via a second coupling piece 41 to a second branch 17B of the middle drive element 17.
  • the lower drive element 27 is wrapped around a guide wheel 23 and is guided from vertical to horizontal direction by two lower guide elements 25 present against the vertical insect screen holder 103.
  • the drive has an elongated, flexible upper drive element 21, which is also formed by a cord and which is connected at both ends to the middle drive element.
  • the two ends 21c and 21d of the upper drive element 21 are connected via the coupling pieces 39 and 41 to both ends of the first drive element 17.
  • the upper drive element 21 is wrapped around a further guide wheel 29 and is moved from vertical to horizontal direction by two upper guide elements 31 located against the vertical insect screen holder 103.
  • the lower driver 11 is connected to a first branch 27A of the lower drive cord 27 and the upper driver 9 is connected to a second branch 21B of the upper drive cord 21. Due to this construction, when the middle drive element 17 is driven, the two drivers 9 and 11 can be moved simultaneously and in the same direction (away from or towards the vertical insect screen holder 103).
  • the drive motor 22 located against the vertical insect screen holder 103 is rotatable about a pivot point 33.
  • the switch 15 is designed as a rotary knob which can also be pressed. Depressing the rotary knob activates the drive motor 22 which moves the drivers 9 and 11 towards the vertical insect screen holder 103, thereby opening the screen door. After some time, a control unit 43 activates the drive motor 22 to move the drivers 9 and 11 back to the position in which the screen door 101 is closed.
  • a sensor 35 and 37 Adjacent to each branch 17A and 17B of the central drive element 17 is a sensor 35 and 37, respectively, for switching off the drive motor 22.
  • These sensors can be designed as switches which are activated by tubes arranged on the ball chain. By adjusting the position of these tubes on the ball chain, the extreme positions are set. However, the sensors can also be designed as counters which count the passing balls and calculate the position of the drivers 9 and 11 on the basis thereof. The extreme positions can then be entered using software.
  • the drive motor 22 is provided on a carriage 47 which can be moved downwards against a spring force. Remotely below the carriage 47, a safety switch 49 is mounted on the vertical tube 103. When activated, this safety switch 49 causes the drive motor 22 to rotate in the opposite direction, so that during the closing of the screen door, when the closing frame 107 is blocked, the drive motor 22 pulls the carriage 47 downwards and activates the safety switch 49 so that the screen door opens again.
  • the switch 15 can also be designed as a motion sensor which activates the drive already when approaching the screen door.
  • a motion sensor 45 can also be present in the upper guide profile 5 near the second end 5B, which motion sensor can be activated, for example, by striking the vertical closing strip 107. In both situations, the screen door can be opened without using the hands.
