Definitions

  • the invention relates to a drive device for a wing of a door, window or the like, comprising:
  • EP2009216 discloses a drive device for a wing of a door which can be swung between a closed position and an open position.
  • the drive device comprises a housing which is mounted on the door frame above the door opening.
  • the housing comprises an electrical drive motor having a motor shaft.
  • the motor shaft is connected to a drive shaft via a transmission mechanism which includes toothed wheels.
  • the drive shaft protrudes from the housing and is attached to a swing arm which is configured to actuate the wing of the door.
  • the housing includes a cylindrical casing having an interior which is provided with a coil spring. One end of the coil spring rests against the inner side of a front end of the cylindrical casing.
  • a cable has one end which is attached to the spring seat.
  • the cable extends from the spring seat through the interior of the coil spring and through a central opening in the front end of the cylindrical casing.
  • the other end of the cable is attached to one of the toothed wheels of the transmission mechanism.
  • the spring means prestressed in its compressed state, it can be used to close the wing of the door.
  • the drive motor fails, for example in case of a power failure, it can be relied upon that the wing of the door can be closed. This is useful for doors which are to be equipped with a fire-protection function.
  • a drawback of this drive device is that it takes up a relatively large space. If the cable is bent over a small radius, it will subjected to significant wear. For this reason, the toothed wheel defines a relatively large bending radius for the cable. As a result, the outer diameter of the toothed wheel is larger than half of the outer diameter of the coil spring and therefore the toothed wheel protrudes with respect to the outside of the coil spring. This affects the required dimensions of the housing of the drive device.
  • An object of the invention is to provide an improved drive for a wing of a door, window or the like.
  • the slidable body comprises at least one reversing guide member
  • the flexible connecting element comprises:
  • the spring means is arranged between the stop and the spring seat.
  • the stop has a fixed or stationary position relative to the rotation axis of the drive member.
  • the spring seat is arranged on the slidable body which can be displaced along the elongate guide member so as to move the spring seat relative to the stop.
  • the flexible connecting element such as a cable, band or belt, is not arranged through the interior of the spring means, such as a coil spring, but extends adjacent to and outside of the spring means.
  • the flexible connecting element may be arranged at a distance from the outside of the spring means. Thus, the flexible connecting element runs at a distance from the longitudinal axis of the spring means.
  • the rotation axis of the drive member can be aligned with or arranged at a relatively small distance from the longitudinal axis of the spring means while it can be safeguarded that the drive member provides a minimum bending radius for the flexible connecting element.
  • the drive member is substantially in register with the spring means.
  • the drive member may be situated adjacent to the stop and substantially in line with the longitudinal direction of the spring means. Consequently, the overall dimensions of the drive device according to the invention can be reduced.
  • the flexible connecting element is connected to the slidable body by means of a reversing guide member, for example a pulley.
  • the flexible connecting element extends from the drive member to the reversing guide member of the slidable body, is guided over said reversing guide member and extends from said reversing guide member to the support structure.
  • the use of the reversing guide member reduces stress in the flexible connecting element, which allows for the use of a relatively light flexible connecting element and prolongs the life of the flexible connecting element.
  • EP624703 describes a chain operator for opening and closing a window, in particular a window designed for installation in an inclined roof surface.
  • the chain operator comprises a housing which accommodates a chain which is guided by guide rails. One end of the chain is designed to extend outside the housing for coupling to the bottom sash member of the sash of the window. Inside the housing, the chain is in operative connection with a drive wheel forming a sprocket wheel for the chain. The sprocket wheel is rotatably mounted in the housing.
  • a counterbalancing spring arrangement may comprise two tension springs connected in parallel. One end of each spring is connected to a common disc which is displaceable in an extension of the housing by means of an adjusting screw.
  • each spring is connected to a flexible element like a wire or cord via a common coupling disc.
  • the coupling disc forms a slidable body which comprises the spring seat for the tension springs.
  • the flexible element is guided from the common coupling disc within the housing by a guide member to a connection on a shaft of the sprocket wheel.
  • the flexible element is connected to and wound around the shaft, so that the flexible element winds up on the shaft as the window moves in a closing direction and unwinds as the window moves in an opening direction. The opening movement is facilitated by compensating for the weight of the window.
  • the overall dimensions of the housing are relatively large.
  • the slidable body formed by the coupling disc does not include a reversing guide member which is moved together with the slidably body.
  • the stress in the flexible element is relatively high, which affects the reliability of the chain operator.
  • EP1428965 describes a door opener having a drive motor.
  • the motor spindle of the drive motor is connected to a shaft via a transmission mechanism.
  • a tension cable is wound up onto the shaft, which is connected to a linear transmission.
  • the linear transmission comprises two cable rollers. One of the cable rollers is attached to a displaceable carriage. The carriage is pushed away from the side the drive motor by springs so as to achieve a good tension in the tension cable within the linear transmission.
  • the carriage is fitted to a plate, which is attached to a pull rod for pulling a connecting rod in the direction of the drive motor.
  • the connecting rod is connected to a piston, which is coupled to a lever for opening and closing the door. With the opening movement of the door, the piston is moved against the force of a closing spring. The closing spring is received between the piston and a stop

  • the tension cable is not connected to the slidable body of the closing spring.
  • the slidable body formed by the piston does not include a reversing guide member for the tension cable which is moved together with the slidably body.
  • the stop defines a first plane which extends substantially parallel to the rotation axis of the drive member and substantially transversely with respect to the elongate guide member
  • the spring seat defines a second plane which extends substantially parallel to the rotation axis of the drive member and substantially transversely with respect to the elongate guide member

  • the reversing part of the flexible connecting element is connected between the first part and the second part.
  • the reversing part is turned over the reversing guide member, and the second part of the flexible connecting element extends back into the direction of the stop.
  • the other end of the flexible element is formed by the end of the second part, which may be attached to the support structure, for example in the vicinity of the stop.

  • the coil springs 10,11 run parallel with respect to the guide rods 16.
  • the coil springs 10,11 are pushed onto the guide rods 16 such that they are prestressed between the stop 9 of the support structure 8 and the spring seat 12 of the slidable body 14.
  • the length of each coil spring is, for example, 440 mm.
  • the outer diameters of the coil springs 10,11 are, for example, 24 mm.
  • the slidable body 14 comprises a first pulley 21 and a second pulley 22.
  • the pulleys 21,22 are rotatably connected to the slidable body 14 by means of a bearing 24.
  • the first pulley 21 and the second pulley 22 substantially have equal pulley diameters and are aligned with respect to each other, i.e. the first pulley 21 and the second pulley 22 substantially have a common pulley axis 25.
  • the common pulley axis 25 is defined by the bearings 24 which are mounted within a central opening in the slidable body 14, for example using bolts.
  • the common pulley axis 25 runs substantially parallel with respect to the rotation axis of the drive wheel 3.
  • a third pulley 23 is mounted to the support structure 9. As shown in figure 3b , the third pulley 23 has a pulley diameter which is smaller than the pulley diameters of the first and second pulleys 21,22.
  • the third pulley 23 has a pulley axis which extends in a transverse direction relative to the rotation axis of the drive wheel 3 and also in a transverse direction relative to the longitudinal axis of the coil springs 10,11.
  • the position of the pulley axis of the third pulley 23 can be adjusted in a direction parallel to the longitudinal axis of the coil springs 10,11 by means of an adjustment screw (not shown).
  • a flexible connecting element 17 is attached to the drive wheel 3.
  • the flexible connecting element 17 is configured as a cable.
  • the cable 17 has two ends which are attached to the drive wheel 3 at positions which are aligned with respect to each other in a direction parallel to the rotation axis of the drive wheel 3.
  • each end of the cable 17 is provided with a bead 18 which is received in a corresponding groove 19 in the drive wheel 3 (see figure 3b ).
  • the grooves 19 are provided on either side of the drive wheel 3.
  • the cable 17 is arranged adjacent to and outside of the coil springs 10, 11.
  • the cable 17 comprises a first part which extends from one end which is attached to the drive wheel 3 to the first pulley 21 of the slidable body 14. From there, the cable 17 is turned over the first pulley 21.
  • the cable 17 comprises a second part which extends from the first pulley 21 of the slidable body 14 to the third pulley 23 being mounted to the support structure 8 and the cable 17 is guided over the third pulley 23.
  • the cable 17 comprises a third part which extends from the third pulley 23 to the second pulley 22 of the slidable body 14. From there, the cable 17 is turned over the second pulley 22.
  • the cable 17 comprises a fourth part which extends from the second pulley 22 to the drive wheel 3, where the other end of the cable 17 is secured to the drive wheel 3.
  • the drive wheel 3 has its first position corresponding to a closed door.
  • the drive shaft of the drive motor 5 rotates the drive wheel 3, for example over a turn of 140°.
  • the cable 17 pulls the slidable body 14 towards the support structure 8 (as shown in figures 5b and 5c ).
  • the drive wheel 3 and the first and second pulleys 21,22 of the slidable body 14 have diameters such that the parts of the cable 17 are arranged at the outer portions of the spring device. This is advantageous for the distribution of forces and also prolongs the life of the cable 17.
  • the third pulley 23 which is connected to the support structure 8 has a relatively small diameter. This does not lead to any significant wear because the third pulley 23 forms an equalization wheel.
  • the middle of the cable 17 is situated at the third pulley 23 and consequently the third pulley 23 only has to compensate for deviations between the length of the first and second part of the cable 17 on the one hand and the length of the third and fourth part of the cable 17 on the other hand.
  • the spring device 7 is symmetrical with respect to a central plane which is perpendicular to the rotation axis of the drive wheel 3.
  • the outer diameter of the drive wheel 3 is situated between the parts of the cable 17.
  • the spring device 7 together with the drive wheel 3 may have relatively small dimensions.
  • the dimensions of the spring device may be 71 x 33 x 603 mm.
  • the width/height dimensions of the drive wheel 3 are equal to or smaller than the width/height dimension of the spring device 7.
  • the drive wheel 3 does not need to protrude with respect to the height and width dimensions of the spring device 7.
  • the drive wheel 3 only increases the length dimension of the spring device 7.
  • the spring device 7 may be covered by a cover housing 26.
  • the elongate guide member comprises hollow guide elements 16.
  • the hollow guide elements 16 may be provided with longitudinal grooves, whereas the slidable body 14 may comprise mating ribs (see figure 7b ). This is advantageous for guiding the slidable body 14 with respect to the hollow guide elements 16.
  • the cable 17 may be replaced by a band, belt or chain.
  • the coil spring or coil springs can be replaced by other spring means.
  • the spring means may be any resilient member.
