Definitions

  • the invention relates to a door closer, the opening arm is connected at one end in a rotationally fixed manner to the door closer drive shaft and at the other carries a sliding element which can be displaced and rotated in a slide rail attached to a fixed frame or the like.
  • It is a so-called overhead door closer with a parallel arm linkage that is attached to the door.
  • the extension arm is guided in a slide rail on the fixed frame, its sliding element being displaced and rotated in the slide rail due to the pivoting of the extension arm when the door is opened and closed.
  • the extension arm is under a pretension that wants to push him away from the fixed frame. As such, it is the task of this door closer to automatically close the door equipped with it after the user has released it. However, there are also situations where you do not want this automatic closing for a certain period of time.
  • the object of the invention is therefore to develop a door closer of the type mentioned in such a way that it also keeps the door open if desired.
  • the invention proposes that the door closer is designed according to the preamble of claim 1 in accordance with the characterizing part of this claim.
  • the sliding element moves in the slide rail when the door is opened, for example from right to left, and consequently when it is closed from left to right. If one now attaches a spring-loaded locking element in the movement range of the sliding element moving in the opening direction at a predetermined position of the slide rail, the door can only be opened until the sliding element has arrived at the locking element and is coupled with it. Coupling is possible due to the spring loading of this locking element against the force of a spring if the door is opened slightly further after the sliding element hits the locking element.
  • the force of the loading becomes again overcome the load spring of the locking element and uncoupled the locking device. Instead, you can also move the locking element back against the force of its loading spring by means of an auxiliary force, so that it releases the sliding element after covering a sufficient distance. After uncoupling, the closing spring of the door closer can have an effect and close the door.
  • the locking element does not have to be attached directly to the slide rail, rather an indirect attachment is also possible and preferably also provided. In addition, it is easy to see that when the locking element is releasably attached to the slide rail, the opening angle at which the door is to be fixed can be changed or adjusted.
  • the locking element can be displaced transversely to the longitudinal axis of the slide rail and thus also transversely to the movement of the slide element in the slide rail.
  • the locking element has a run-up slope and a catch receptacle for the sliding element which adjoins it in the direction of movement of the sliding element. About this ramp bevel the locking element is pushed back by the sliding element when the door is opened against the resistance of its loading spring. As soon as the sliding element arrives in front of the latching receptacle, it springs into it in a spring-driven manner and thereby causes the door to be locked, the locking element returning to its starting position.
  • the latching receptacle is provided with at least one oblique side edge which is adjacent to the run-up slope and is inclined in opposite directions thereto.
  • the run-on slope as the run-in run-up slope and the sloping side edge as the run-out run-up slope.
  • the locking element can be displaced by means of a sliding member which can be displaced in a housing or the like which can be fastened to the slide rail.
  • This housing can be attached to the desired position on the slide rail and possibly adjusted by moving it to one side or the other so that the open locking angle of the door is reached.
  • the opening arm of the door closer is spring-loaded, the spring loading the opening arm arranged approximately parallel to its plane in the direction of an inclined position when the door is closed. This complicates the assembly of the door closer, in particular the opening arm in the slide rail, because the latter has to be inserted into the slide rail with its free end or its slide element.
  • the door closer is designed in accordance with the preamble of claim 15 in accordance with the characterizing part of this claim.
  • the mounting rail On the fixed frame or the like, in particular on its upper cross member, the mounting rail is first attached. Because this is separated from the slide rail at least prior to assembly, the force of the load spring acting on the extension arm cannot have an effect when the assembly rail is struck. When this is installed, the slide rail is connected to it, on which the door closer is already located. While the slide rail is usually screwed to the fixed frame, which requires a relatively long amount of time and precise work, and is also made more difficult by the spring force of the extension arm, the slide rail can be attached to the mounting rail with the mounting rail by plugging, sliding or in another known quick connection type relatively quickly couple and then, if necessary, secure the connection. This is done much faster than screwing the slide rail in the prior art or the mounting rail of this door closer. As a result, the force of the spring hardly has a disadvantageous effect when a mounting rail is used, so that this door closer can be assembled more easily overall and, ultimately, because the spring is no longer obstructed, it can also be installed more quickly.
  • the slide rail and the mounting rail are coupled in a form-fitting manner. So you can put them together relatively quickly.
  • a further development of the invention provides that the slide rail can be placed on the mounting rail from above, with a downward-facing strip of the slide rail engaging behind another strip of the mounting rail pointing in the opposite direction. As soon as you have slid the slide rail with the door closer onto the mounting rail from above, the assembly is at least largely completed. If you do not have a locking or similar automatic connection, you only have to secure the slide rail in relation to the mounting rail in the lifting direction.
  • 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 opening 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 displacement 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.
  • Ordered edge 22 of the locking receptacle 21 is also formed as a run-up slope, but with an oppositely directed 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 runs perpendicular to that of the locking member 15.
  • the sliding member and the locking member can be moved via a tab or a link 26 as coupled, which is articulated on the locking member 15 via an axis 27 and articulated on the sliding member 24 via a further 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. When 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 assembly 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 electrically connected, for example, 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.
