Definitions

  • the present invention relates to a module for transferring rotational motion to an openable and closable element, such as a door leaf, and a system comprising a module.
  • actuators are used.
  • the actuator is an opener or a closer, i.e. it is either adapted to apply power in order to move an element from a default position, such as a closed position, or apply power and/or release power in order to move an element to a default position.
  • An actuator referred to as an opener is commonly designed to move a door leaf from and to a closed position and is hence commonly designed to open and close a door leaf. When used for opening and/or closing a door leaf, the actuator is often placed above the door leaf.
  • a common problem when designing such a system is that the desired torque varies with the opening angle of e.g. the door leaf. It may, for example, be necessary for a door leaf closer to apply a large torque for small opening angles in order to properly move the door leaf into a latched position. Vice versa, it may be necessary for a door leaf opener to apply a higher torque at small opening angles in order to move the door leaf from such a latched position. Although there exist some solutions aimed at this problem, they are often bulky, sensitive to damage and sabotage, not protected from weather and fouling, and aesthetically unpleasing.
  • An object of the present invention is therefore to overcome the above problems, and to provide a solution that at least to some extent improve upon the prior art.
  • Another object is to provide such a module which is compact.
  • Another object is to provide such a module which is protected from weather and fouling.
  • Another object is to provide such a module which is less time consuming to install.
  • Another object is to provide such a module which is less exposed to outside access, such that it is not easily damaged or sabotaged.

  • the link arm system may be configured such that an instantaneous ratio of the motion of the second end portion of the second link arm and the rotational motion of the rotation pin varies depending on a rotation angle of the rotation pin about the axis of rotation.
  • the module may e.g. be configured to apply a large torque to the openable and closable element at small rotation angles of the rotation pin and a smaller torque to the openable and closable element at large rotation angles of the rotation pin.
  • the module when the module is mechanically connected to a door leaf arranged in a door frame, the module may be configured to apply a large torque at small opening angles, i.e. when the door leaf makes a small angle in relation to the door frame, and a decreasing torque with larger opening angles.
  • the module may further comprise a bracket assembly attached to the end portion of the rotation pin in a torsionally fixed manner and configured to be fastened to the openable and closable element.
  • bracket assembly By mechanically connecting the module to an openable and closable element via a bracket assembly, a larger area of contact between the module and the openable and closable element may be achieved.

  • the elliptical through-hole 43 may have any other oblong shape.
  • a position of the eccentric element 41 may as such be changed within the elliptical through-hole 43.
  • the eccentric element 41 comprises a means for receiving a tool 45 adapted to receive a tool for changing the position of the eccentric element 41.
  • the means 41 has a hexagonal shape, and is thus configured for receiving e.g. a hex key.
  • the angle ⁇ of a longitudinal extension LA1 of the rotation arm 37 in relation to a longitudinal extension LA2 of the fastening element 39 is altered.
  • the eccentric element 41 may further be lockable by means of a locking member 47 arranged in the eccentric element 41. As such, the position of the eccentric element 41 in the elliptical through-hole 43 may be fixed.
  • the eccentric element 41 may further alter the effective opening angle of the openable and closable element, when it is in a closed position.
  • the eccentric element 41 is e.g. configured to set the opening angle within an interval of 10 degrees.
  • arrangement of the eccentric element 41 may be set such that the resulting opening angle is -5 degrees, which results in an even larger torque arm, and thus resulting torque.
  • Fig. 5 shows a system 8 according to the second aspect of the present invention, comprising a module 1 attached to a longitudinal profile element 6.
  • the longitudinal profile element houses an actuator 4 mechanically connected to the module 1.
  • the module 1 and the longitudinal profile element 6 are arranged in a door frame 12.
  • the system 8 further comprising a bracket assembly 35 fixedly arranged on the openable and closable element 10 so as to co-rotate with the openable and closable element 10 about the element axis of rotation
