Definitions

  • the invention relates to a door closer according to the preamble of claim 1. It is a so-called overhead door closer with a parallel arm linkage which is attached to the door. Such a loss arm is guided in the slide rail on the fixed frame, its sliding element being displaced and rotated in the slide rail due to the pivoting of the opening arm when the door is opened and closed.
  • the extension arm is under a pretension that wants to push it away from the fixed frame. In itself, it is the task of this door closer, the door equipped with it after the release by the user automatically close again. However, there are situations in which you do not want this automatic closing at least for a certain period.
  • a second possibility is to disengage the locking device by means of an assistant. As soon as this disengagement has taken place, the power of the door closer can be released take effect, which leads to the closing of the door.
  • This auxiliary force is, for example, an electronic magnetic force which, however, does not act directly, but indirectly.
  • the auxiliary member With the help of the current-carrying magnet, the auxiliary member is held in such a rotational position that the locking element supported thereon via a compression spring assumes its effective position.
  • the auxiliary element is released by the magnet.
  • This also eliminates the locking force of the locking device and, as a result, the closing force of the door closer can have an effect in the sense of a closing movement of the door.
  • the sliding element presses on the locking element and its load spring on the auxiliary member and pivots it away from the magnet. However, when the latter is energized again, it pulls the auxiliary member again, which then also brings the locking element back into its effective position.
  • the object of the invention is therefore seen in developing a door closer according to the preamble of claim 1 so that the locking angle of the door can be freely selected at least within certain limits with simple assembly.
  • the locking is effected exclusively via the sliding element and the locking element, because the sliding element is locked with the locking element, it is held in both sliding directions after the locking, which is why the door can only be opened until this locking has taken place. It is easy to see that when the locking element is detachably attached to the slide rail, the opening wikih at which the door is to be fixed can be changed or adjusted. This has an advantageous effect that the locking element and the sliding member are slidably mounted on the housing attached to the slide rail and the housing can be mounted at a suitable and desired location on the slide rail.
  • the locking element is pushed back against the resistance of its load spring when the door is opened further.
  • the force of the loading spring can change impact and the locking receptacle then holds the sliding element in that the locking element returns spring-driven to its initial position. This holds the door.
  • the disengagement is easily possible due to the second bevels forming one of the two flanks of the snap-in receptacle.
  • the first run-up slope can be described as the run-in run-up slope and the second as the run-out run-up slope.
  • the door 1 is rotatably mounted on a fixed frame 2. For this purpose, it has at least two rotary bearings 3 arranged one above the other, the upper one of which can be seen in FIG. 1.
  • a door closer 4 is attached, which is consequently designed as a so-called overhead door closer.
  • the slide rail 5 is located on the fixed frame, into which the slide element 7 attached to the free end of an extension arm 6 coupled to the door closer 4 is perpendicular to the image plane of FIG. 3 is slidably mounted.
  • the end of the opening arm 6 on the door closer side is coupled in a rotationally fixed manner to the drive shaft 12 of the door closer.
  • the sliding element 7 consists of an axis 10 and a sliding roller 11 arranged at its free end. If one limits the sliding movement of the sliding element in the sliding rail when the door is opened, the door can be opened only open up to an angle of rotation corresponding to this shift distance. Furthermore, there is the possibility in an advantageous manner to determine the door which has been opened so far. This is expediently done by means of a locking device 13 that automatically comes into operation. It has a housing 14 in which a locking element 15 is mounted so as to be displaceable in the direction of the double arrow 16 against the resistance of a return spring 17. The displacement movement is directed transversely, in particular perpendicularly to the longitudinal axis of the slide rail 5.
  • the sliding element 7 When the door is opened, the sliding element 7 approaches a run-up slope 19 of the blocking element 15, which is directed, for example, at approximately 45 ° to the longitudinal axis of the blocking element. Finally, it hits this run-up slope and displaces the locking element 15 in the direction of arrow 20 against the resistance of the return spring 17. In the direction of arrow 18, a catch receptacle 21 connects to the run-up slope 19.
  • the spring-loaded locking element 15 springs back into its starting position against the arrow 20, as a result of which a locking or coupling takes place. Because the sliding movement of the sliding element 7 in the slide rail 5 is now blocked, the door cannot be closed by the door closer. It is assumed that the spring 17 and the restoring force of the door closer are designed accordingly.
  • Edge 22 of the snap-in receptacle 21 is also designed as a run-on slope, but with an opposite inclination. If a sufficiently large force acting against the arrow 18 acts on the sliding element 7, this again results in the locking element 15 being displaced in the direction of the arrow 20. As soon as the sliding element has passed over the hump 23 and is completely outside the displacement range of the locking element, the latter can return to the starting position. This release force is due to a manual closing movement of the door. After uncoupling the door can be released so that it is automatically closed with the help of the door closer.
  • a second possibility of uncoupling the sliding element 7 and the locking element 15 or the release of the locking device is achieved by moving the locking element 15 in the direction of the arrow 20 by means of a corresponding assistant.
  • This can be both a manual force and another known auxiliary force, for example an electromagnetic force.
  • the optional triggering of the locking device 13 is provided by means of a manual force.
  • a sliding member 24 in the sense of the double arrow 25 is slidably mounted in the housing 14 of the locking device 13.
  • the guide for the sliding member 24 is perpendicular to that of the locking member 15.
  • the sliding member and the locking member are movable via a tab or a link 26 coupled, which is articulated on the locking member 15 via an axis 27 and articulated on the sliding member 24 via an additional axis 28. From Fig.
  • the longitudinal axis of the handlebar or a straight line defined by the geometric axes of the axes of rotation 27 and 28 with the dash-dotted longitudinal central axis 29 of the locking member 15 or a line parallel thereto includes an acute angle.
  • the straight line through the axes 27 and 28 forms an obtuse angle with a longitudinal axis 30 of the sliding member 24.
  • this longitudinal axis 13 is an imaginary line parallel to the longitudinal edges, which extends laterally offset to the non-drawn longitudinal center line of the sliding member 24.
  • the sliding member 24 can be deflected against the resistance of a return spring 17 when engaging and disengaging.
  • This spring is supported on one end on a shoulder 31 of the sliding member 24 and on the other end on a shoulder 32 of the housing 14 of the locking device 13. It is preferably in each case pressed-in bolts.
  • the sliding member 24 can be displaced by means of a rotatable actuating member 33 against the resistance of the spring 17. It is rotatably mounted in the housing 14 and carries two internal eccentrics 34 in the exemplary embodiment. The axis of rotation of the actuating member is designated 56.
  • the eccentrics 34 bear against a push-off surface 35 of the sliding member 24, which is formed by the inner surface of a wall 36 of the sliding member 24 remote from the blocking element 15.
  • Each eccentric is based on that in FIG. 7 drawn position after a 180 ° rotation in a dead center position. Since each eccentric engages in a lateral recess 57 of the sliding member 24, it is positively coupled in both sliding directions. In the dead center position of the eccentric 34, the locking element is in its ineffective position.
  • an electromechanical or magnetic adjustment can take the place of the mechanical adjustment of the locking member.
  • the sliding member 24 is coupled to the armature of an electromagnet. If this is excited, the locking element assumes its locking or working position. If the current is interrupted, the magnet pulls the locking member into an ineffective position in which the door cannot be locked by the locking device 13.
  • the slide rail 5 is equipped with a mounting groove 37 which receives a sliding block 38. It is provided with at least one thread into which a screw 39 is screwed. It passes through a wall 40 of the housing 14 of the locking device 13. If the screw has not yet been tightened, the locking device 13 can be displaced perpendicular to the image plane of FIG. 4 along the slide rail 5 and locked in place by tightening the screw 39.
  • the slide rail 5 is attached to the fixed frame 2 indirectly via a mounting rail 41.
  • the latter is first mounted on the fixed frame 2, in particular screwed on. Their length suitably corresponds approximately to that of the slide rail 5.
  • the slide rail and the mounting rail 41 are coupled in a form-fitting manner.
  • on the slide rail there is a bar 42 which points downward in the mounting position and which engages behind another bar 43 of the mounting rail 41 which points in the opposite direction.
  • the slide rail strip 42 is part of a U-shaped receptacle 44 of the slide rail 5 in cross section.
  • the lower end of the slide rail 5 on the mounting rail side is supported on a front surface 46 of the mounting rail 41. This runs in particular parallel to the contact surface 48 of the fixed frame 2.
  • the slide rail 5 is plugged onto the screwed mounting rail 41 from above in the direction of arrow 49, the surfaces 46 and 48 being used for reliable guidance.
  • the assembly of the slide rail 5 has essentially already been completed, so that the force of the spring acting on the extension arm 6 can no longer have a disruptive effect.
  • This mounting position only has to be secured. This is done with the aid of a plurality of screws 47 arranged next to one another in the longitudinal direction of the rails.
  • a longitudinal groove 51 which is preferably designed as a dovetail groove. It can be used, for example, to insert an opening limitation which, similar to the locking device 13, is inserted and clamped therein. It can be equipped with a projection protruding into the rail interior, which protrudes into the movement path of the sliding element 7, in particular the sliding roller 11. By moving in the groove 51, you can also set the limit angle here as desired.
  • a cover profile 52 in the mounting groove 37 for example.
  • Corresponding current collectors are located on the housing 14 and are, for example, electrically connected to the electromagnet. The housing 14 can thus be moved as desired along the slide rail 5 without there being any problems with regard to the power supply to the electromagnet or the like.
