Definitions

  • the invention relates to a braking device, in particular for door closers, in which there is a brake shaft with a brake wing which can be moved in a closed housing filled with brake medium, and in which a brake wall which divides the housing interior together with the brake wing which can be pivoted by the brake shaft is fixed in the housing is arranged, the brake wing for the passage of the brake medium has a recess and the flow cross-section determining the braking effect for the brake medium is different along the brake wing movement path.
  • a door locking device in which a brake wing can be pivoted in a housing filled with a liquid and has a recess for the passage of the brake medium.
  • the inner wall of the housing is provided with grooves on part of the brake vane movement path, which have the effect that the flow cross section for the brake medium is different when the brake vane is rotated.
  • the disadvantage is that the braking process cannot be changed.
  • the invention has for its object to improve a braking device of the type mentioned in such a way that the braking process is changeable and can be individually adapted to the respective circumstances.
  • this object is achieved in that a ring coaxial with the brake shaft and rotatable about the axis thereof engages in the recess in the brake wing, on which one of its boundary surfaces facing the brake wing is designed as a control curve which, when the brake wing is pivoted, the passage cross section for the brake medium and so that the braking intensity changes according to their training, the braking medium being viscous or pasty material.
  • the ring containing the control cam can be rotated relative to the housing, the movement sequence can be changed in a simple manner without having to replace parts or that sealing problems arise.
  • the braking device has a brake shaft 1 to which a brake wing 2 is rigidly attached or consists of one piece with it.
  • the part of the brake shaft 1 protruding from the housing 3 is designed as a square 27.
  • the brake wing 2 can be moved in a closed housing 3 filled with a brake medium.
  • In the interior of the housing 3 there is an essentially radial, stationary brake wall 4 which extends as far as the brake shaft 1 and divides the interior of the housing together with the brake wing 2 which can be pivoted by the brake shaft 1.
  • two chambers are formed in the interior of the housing, one of which increases when the brake wing 2 moves and the other decreases to the same extent.
  • the brake wing 2 has a recess 5 into which a ring 6, which is concentric with the brake shaft 1, projects.
  • the upper end face of the ring 6 is designed as a cam 7. Due to the distance between this control curve 7 and the edge of the recess 5 of the brake wing 2 running parallel to the control curve 7, an average gap 20 results for the brake medium during the pivoting of the brake wing 2.
  • the ring 6 lies against the cylindrical inner wall 9 and against the floor 11 of the housing 3. On its inner ring surface, the ring 6 has a toothing 12 into which a pinion 13 engages from below. This can be rotated coaxially to the housing inner wall 9 by means of a handwheel 14. As a result, the control cam 7 can be rotated inside the housing.
  • the passage cross-section for the brake medium can be varied so that e.g. the closing movement of a door can be controlled as desired by varying the braking intensity during the closing process.
  • the control curve 7 is provided with a step 28, as a result of which the flow cross section - that is to say the gap 20 - is narrowed above the control curve 7. As a result, the rotary movement of the brake wing 2 is slowed down.
  • a step 28 it would also be possible to provide the control cam 7 with a constant slope, similar to a thread, this slope preferably extending only over part of the ring circumference.
  • the brake wall 4 also has a recess 15 which extends over the ring 6. Since the part of the recess 15 opposite the control curve 7 must have such a distance from the control curve that even the highest elevation of the latter can still be moved freely, at least when the highest elevation is not within the recess 15 of the brake wall 4 , an additional passage for the brake medium is available. In order to prevent this additional passage for the brake medium, a height-displaceable slide 16 is arranged within the brake wall 4, which is pressed by a spring 17 against the control cam 7, whereby the brake wall 4 is sealed off from the ring 6.
  • the slide 16 can be lifted off the control cam 7 via a screw spindle 18.
  • the screw spindle 18 penetrates the pinion 13 and can be moved independently of it.
  • a check valve 19 is installed in the brake wing 2.
  • the check valve 19 contains a movable cylindrical valve piece 22 which is inserted into the brake wing 2. Radial bores 23 open into the central cavity 24 of this valve piece 22.
  • the valve piece 22 is provided at both ends with annular stops 25. In the position shown in Fig. 2, the check valve 19 is closed. If the valve piece 22 is moved relative to the brake wing 2 in the direction of arrow A, a flow can take place via the cavity 24 and the bores 23.
  • Viscous or pasty material which may consist of mixtures of fats and fatty substances, is preferably used as the braking medium, the choice of the braking medium and its viscosity, in order to take seasonal changes into account, depending on the climatic conditions in the area in which the brake fluid is used to be used.
  • the fact that such brake media are practically incompressible means that any change in the passage cross-section immediately has an effect on the brake intensity.
  • the damping of the closing movement can be set as desired, since the passage opening for the brake medium can be chosen to be larger or smaller, which results in a lower or higher braking intensity.
  • a fine adjustment of the braking intensity can be achieved in that a constant passage of the brake medium through the recess 15 in the brake wall 4 is released by more or less slight lifting of the slide 16 from the control curve by means of the screw spindle 18, whereby the lifting of the slide 16 with the Handwheel 26 can be regulated very precisely.
  • An embodiment variant consists in that the toothing 12 extends only over a part of the circumference of the ring 6 and the remaining part of this surface is designed as a control curve which is thus rotated by 90 ° to the embodiment shown in FIG. 1.
