Definitions

  • the invention relates to a device for locking and / or braking a wing of a door or a window, according to the preamble of claim 1.
  • EP 0 321 649 B1 can be mentioned.
  • the determination is made via a projecting into the path of movement of the slider detent.
  • This locking lug is mounted in one of two electromagnets, movable armature plate, which is detected when energizing the magnets, thereby preventing retraction of the locking lug.
  • movable armature plate which is detected when energizing the magnets, thereby preventing retraction of the locking lug.
  • hydraulic door drives with piston-cylinder device are known, which allow a hydraulic detection of the door.
  • Such drives with piston-cylinder device are known, for. B. as electro-hydraulic door drives for motorized opening of the door via a hydraulic pump and closing via a closing spring (DE 32 02 966 A1) or as a hydraulic door closer, in which the door is opened manually and hydraulically damped by the closing spring is closed (DE 25 35 244 A1, DE 36 38 353 A1).
  • These known hydraulic systems each have a piston-cylinder unit with hydraulic circuit.
  • To adjust the opening or closing speed regulating valves are provided in overflow.
  • the regulating valves are manually adjustable to adjust the flow velocity and thus the opening and closing speed.
  • Electrically switchable valves in the overflow of such drives are known as electromagnetic check valves to determine the door in an open position or to set a certain hold time.
  • the solenoid valves used are very large and require a lot of electrical energy.
  • the object of the invention is to provide a device for detecting and / or braking a wing of a door or a window, which has a small size.
  • the aim is also high reliability and reduced susceptibility to interference.
  • the invention solves this problem with the subject matter of claim 1.
  • Used as piezo elements trained actuators for detecting, braking or damping of the wing. These actuators generate the low-power electrical supply for blocking, d. H. for detecting, braking, damping, required travel and actuating forces.
  • the complex mechanical transmission elements hitherto required in the blocking device can be dispensed with, since piezoelectric elements can be applied directly at the detection location.
  • annular sliding body is designed as a piezoelectric element.
  • the piezoelectric element is guided on a guide rod received axially in the rail. When electrically charged, the piezoelectric element undergoes a cross-sectional constriction, whereby it is fixed on the guide rod.
  • FIG. 1 a single-leaf door 1 with an overhead door closer 21 is shown in FIG.
  • the door 2 is hinged at its right vertical edge in the drawing via two bands 2a on the right vertical spar of the door frame 5.
  • the closer shaft 21a of the door closer 21 attached to the door leaf 2 is connected to a sliding arm 21b to be designated as a slaving arm 21b.
  • the shutter arm 21 b is slidably guided in a mounted on the upper horizontal bar of the door frame 5 slide rail 4 by the arm 21 b with a hinged at its free end slider 21 c (FIG. 3), which may also be designed as a roll in the rail 4 engages through a guide slot 41 from below.
  • FIG. 1 a so-called new actuator in the form of a piezoelectric element 6 is shown in FIG.
  • This simple piezoelectric element 6 of cuboidal shape with the thickness d and the length I has two opposing electrodes 6a, which are connected via connecting lines 7b to the two poles 7a of a controllable voltage source 7. If a voltage and thus also an electric field are applied across the two electrodes 6a, then the piezoelement 6 reacts with a change in length I 'which is related to the height and the polarity of the voltage.
  • the new shape of the piezoelectric element 6 is outlined in the figure with dashed lines and designated by the figure number 6 '. Since the volume of the body thereby remains almost constant, the piezoelectric element 6 responds to each longitudinal extension in addition to a transverse shortening, which is not shown in the figure. If the change in length of the piezoelectric element 6 is prevented by external conditions, then a force effect is evident which is directed counter to the cause of the prevention. In practice, both the longitudinal extension and the transversal shortening can each be used in conjunction with the corresponding force effect.
  • piezoelectric elements 6 are often made in stacked construction. In principle, however, elements can be produced in any desired form.
  • FIG. 3 shows a longitudinal section of the rail 4 in FIG. 1 with the schematic sketch of an actuator-controlled locking device 9 according to the invention. Shown is the closer arm 21 b with an annular sliding body 21 c articulated at its end. Via an opening 41 of the slider 21c engages from below into the rail 4 and is threaded onto a received in the rail 4, axially extending between the end faces guide rod 42.
  • the annular sliding body 21 c is designed as a piezoelectric element 6.
  • a controllable voltage source 7 is provided, which is preferably arranged on one of the end sides of the rail 4.
  • the voltage source 7 is connected via connecting lines 7b to the two electrodes 6a of the piezoelectric element 6.
  • the control of the voltage source 7, which can be done both manually and via a in the rail 4 or otherwise arranged contact switch. Without limitation of the functionality is just as conceivable to arrange the power supply 7 separately or shared for several door closers.
  • a contact rail may be arranged in the rail 4, which cooperates with sliding contacts on the slider 21 c.
  • the piezoelectric element 6 can also be designed so that it firmly surrounds the guide rod 42 in the de-energized state (ie is determined) and upon application of a voltage widening of the annular surface experiences (ie axially on the guide rod 42 is movable).
  • the slider 21 c only partially consists of one or several piezo elements. Also, changes in the cross-sectional configuration of the guide rod 42 and piezoelectric element 6 are conceivable as long as the leadership of the piezoelectric element 6 is ensured on the rod 42.
  • the piezoelectric element 6 is not guided on, but within an axial guide receptacle and at least partially enclosed by it is possible.
  • the force occurs at an enlargement of the piezoelectric cross section.
  • the rail 4 also represents the guide receptacle.
  • the piezoelectric element 6 is integrated in or on the guide rod 42 and the slider 21c as a conventional body z. B. made of metal, plastic or the like.
  • the illustrated door 1 has two stop door wings 2, 3.
  • the right wing 2 in FIG. 1 is articulated on its right vertical edge via two bands 2 a on the right vertical spar of the door frame 5.
  • the left wing 3 is articulated on its left edge via two bands 3a on the left frame member.
  • the right wing 2 has a stop web 2b, to which the overturning fold web 3b of the left wing 3 applies in the closed state of the door. This requires that for closing the door 1 in each case first the right wing 2 - the so-called passive leaf - and then the left wing 3 - the so-called active leaf - comes into the closed position.
  • the left wing as a passive leaf and the right wing can be designed as a moving leaf.
