Definitions

  • the invention relates to an overhead door closer in which a door closer arm is guided in a slide rail on the door frame side by means of a slide piece articulated to the door closer arm and a mechanical device which can be set up is provided for limiting the guide region of the slide rail for the slide piece in the slide rail.
  • Such a door closer is known from the company publication "GEZE door closer", printed note 9.89. It is an overhead gear door closer with a slide rail with the designation T 5000.
  • the opening angle at which the open door can be locked can be adjusted continuously between 80 ° and 130 ° via a mechanical lock.
  • a locking device for door leaves with a door closer is known, the closer shaft of which is coupled to one end of an actuating arm, the other end engages via a slide in a guide rail which is assigned a holding unit which defines the slide in a certain open position.
  • the holding unit has a locking knob which is loaded by a spring element in the locking direction and engages on the sliding piece.
  • Such a locking device extends essentially transversely to the direction of displacement of the slider and can not be accommodated in the known guide rails because of the size. Such a locking device can be pushed over to completely open a door.
  • the invention has for its object to provide a simple mechanical locking device for an overhead door closer of the type mentioned, which can be put in place from the outside and re-established.
  • the locking devices are arranged in this door closer according to the invention in the slider and therefore do not take up any additional volume. It exists the possibility of overriding these locking devices, which fix the associated doors at a certain opening angle, so that the doors can be fully opened, for example. In a simple manner, it is also possible to switch on the locking devices again.
  • a preferred embodiment of the door closer is specified in claim 3.
  • the non-round rod is rotated by moving the associated sliding sleeve when the twisted transition piece is passed over. Due to the changing outer diameter, the respective blocking element is therefore displaced in the transverse direction of the slide rail and, together with a locking element on the rail side or directly with a slide rail wall, forms the mechanical locking device.
  • the locking device can be set up in the longitudinal direction of the slide rail according to claim 8 by moving the locking element or by an adjustable attachment on the rotatable rod according to claim 9.
  • the locking device can also be designed according to claims 12 and 13 according to the principle of a slip clutch in order to avoid overloading the door closer or its correspondingly loaded parts in the event of an overload on the door closer arm.
  • FIGS. 1-6 the door closer arm 2, which is articulated to the gearbox accommodated in the housing and which is guided with its end in the slide rail 3 to be fastened on the door frame side, can be seen.
  • the corresponding end of the door closer arm 2 is connected in an articulated manner to a slide piece 4, which is guided in the slide rail 3, which is C-shaped in cross section and open at the bottom.
  • a rod 5 with a square cross section is guided with little play and is rotatably supported at its ends in the end plugs 32 and 33 of the slide rail 3.
  • the diameter of the bore 41 corresponds approximately to the diagonal of the cross section of the rod 5.
  • this rod 5 has a transition piece 51 twisted by 45 °.
  • a sliding sleeve 6 is positively placed on the rod 5 with a corresponding bore and can be moved in the axial direction from the outside via the grip element 61. If this sliding sleeve 6 passes over the transition piece 51, the rod 5 is rotated in each case by 45 °.
  • a locking device described below is actuated by this displacement of the sliding sleeve 6 or the resulting rotation of the rod 5.
  • a chamber 42 is provided, which is open towards the top of the slide rail wall 31 and in which a plate-like blocking element 8, preferably made of plastic, is accommodated in a form-fitting manner but radially to the axis of rotation of the non-circular rod 5.
  • This blocking element 8 rests on the non-circular rod 5, which is preferably square in cross section.
  • a locking element 7 projecting slightly into the slide rail 3 is provided in a slot 311 which can be displaced in the longitudinal direction of the slide rail.
