Definitions

  • the invention relates to a door opener with a locking / releasing device for a pivot latch of the door opener with a locking lever which locks or releases the pivot latch, and a safety lever which holds the locking lever in a locked position and pivotable by means of an electromagnet in a position releasing the locking lever is.
  • a lock / release device of a door opener with an arrangement of two safety levers of the above type wherein the second safety lever secures the first safety lever.
  • an electromagnet is arranged to control the two safety levers.
  • the second of the first mechanically decoupled locking lever is connected by magnetic coupling with one end of the electromagnet in operative connection and is adjustable from a first locking lever locking position in this releasing position.
  • an extendable from the coil winding body of the electromagnet pin for adjusting the first safety lever is provided.
  • barrier / release devices with impact protection have many, sometimes very delicate components, which are complex to manufacture and assemble.
  • the invention has for its object to provide a door opener with a locking / releasing device for a pivot latch, which makes do with a simple construction for impact protection of the door opener while allowing efficient production and assembly.
  • the safety lever is mounted in its center of mass.
  • the pivot or rotation axis is thus in the center of mass.
  • a preferred embodiment is that the safety lever is pivotable parallel or perpendicular to the axis of rotation of the pivotal latch.
  • the orientation and arrangement of the safety lever can be chosen depending on the installation position of the door opener.
  • the safety lever is symmetrical. This simplifies the mass balance of the safety lever.
  • an asymmetrical design is also conceivable, wherein the mass balance over the materials used for the respective areas of the safety lever is achieved. This may be required in confined spaces.
  • a preferred embodiment is that the safety lever has two lever arms and the electromagnet is in operative connection with the one lever arm and a compression spring in operative connection with the other lever arm.
  • the operative connection between the electromagnet and the one lever arm is greater than the operative connection between the bias voltage and the other lever arm.
  • the other lever arm of the safety lever is subjected to a bias voltage.
  • the force exerted on this lever arm due to a compression spring causes a rotation of the safety lever about the axis of rotation lying between the two lever arms in the center of gravity of the safety lever.
  • the torque effect generated from the bias voltage is smaller than that from the operative connection between the electromagnet and the safety lever.
  • the first and the second lever arm are aligned linearly and substantially in one direction.
  • the orientation of the lever arms is essentially dependent on the arrangement of the electromagnet.
  • the safety lever or the solenoid can be arranged vertically or horizontally.
  • the safety lever is assigned a micro-switch for monitoring the position of the safety lever. It is expedient that the microswitch is assigned to the acted upon by the compression spring lever arm. It is advantageous to arrange the microswitch and the compression spring on opposite sides of the lever arm. Due to the acting spring force, the lever arm then actuates the switch contact or moves away from it when the electromagnet is energized, wherein the state changes are respectively detected by the microswitch.
  • Fig. 1 shows in a side view with the housing cover removed a locking / releasing device of a door opener 15 in the locked position with a pivot latch 5, a locking lever 4, a safety lever 1 and an electromagnet 3, which is in operative connection with the safety lever 1.
  • Fig. 1 In this blocking position, the door opener is in a safe position, ie opening of the door opener, for example, by accidental, non-intended exposure to shock, vibration or violence is not possible ,
  • the locking lever 4 prevents the pivot latch 5 in the in Fig. 1 shown blocking position because it can be adjusted in the release position (not shown).
  • the locking lever 4 is integrally formed and rotatably supported about an axis 12. So that it can be returned from the release position to the blocking position, it is acted upon by means of a compression spring with a bias voltage (not shown).
  • a detent 13 is formed to allow engagement with the safety lever 1.
  • the substantially transverse (or perpendicular) to the locking lever 4 aligned safety lever 1 is rotatably mounted in its center of mass or center of gravity about a centrally disposed axis of rotation 10. Furthermore, it is symmetrical and integrally formed.
  • the safety lever 1 has two lever arms 6 and 7, which are arranged substantially linearly, in a direction parallel to each other and with a slight offset from each other.
  • On a side facing the pivotal catch 5 side of the first lever arm 6 is a compression spring 11, which acts on the first lever arm 6 and thus the safety lever 1 with a bias voltage. This compression spring 11 is used to return the safety lever 1 from the release position of the locking lever 4 in the locked position.
  • the second lever arm 7 located on the opposite side of the first lever arm 6 and adjacent to the locking lever 4 has a metallic or magnetic counterpart 16 on the side surface facing the electromagnet 3.
  • the locking lug 13 of the locking lever 4 engages on the latching edge 9 of the second lever arm 7 of the safety lever 1 on the opposite side surface of the second lever arm 7 is a linear sections, extending at right angles to each other in the form of a Abtreppung on that the locking lever 4 can not be rotated in the release position.
  • the locking edge 9 can also be designed in the form of a recess.
  • Fig. 1 further shows a microswitch 2 with a switch contact 17 for monitoring the position of the safety lever 1 and Hebelarms 6. This is at a transition to the blocking position provided that caused by the compression spring 11 rotation of the lever arm 6 of this with its side surface 8, the switch contact 17 is actuated and thus the microswitch 2 detects the blocking position. In a transition to the release position, the side surface 8 of the lever arm 6 moves accordingly away from the switch contact 17 and releases it. This state change is detected by the microswitch 2.
  • the microswitch 2 is aligned substantially parallel to the electromagnet 3, wherein both are arranged substantially perpendicular and above the safety lever 1 on the housing 14.
  • the direction of action of the electromagnet 3 extends substantially vertically or perpendicular to the lever arms 6 and 7 of the safety lever 1.
  • the electromagnet 3 consists of a coil winding body.
  • the electromagnet 3 has a stop contact 18, on which the counterpart 16 of the second lever arm 7 comes to rest.
  • the starting from the electromagnet 3 attraction to the counterpart 16 of the second lever arm 7 is designed so that the operative connection between the electromagnet 3 and the second lever arm 7 is greater than the operative connection between the compression spring 11 and the lever arm 6 of the safety lever 1.
  • the torque effect exerted about the axis of rotation 10 of the safety lever 1 by means of the compression spring 11 is such that it is smaller than the operative connection between the electromagnet 3 and the lever arm 7.
  • Fig. 2 are the same parts as in Fig. 1 denoted by the same reference numerals.
  • Fig. 2 is the lock / release device of the door opener 15 according to Fig. 1 shown in a side view with removed housing cover in the release position.
  • This the locking lever 4 and thus the pivot latch 5 releasing position is achieved by an adjustment or rotation of the safety lever 1 after energization of the electromagnet 3.
  • the energization of the electromagnet 3 wherein this then exerts an attractive force on the counterpart 16 of the second lever arm 7 of the safety lever 1.
  • This force must, as already explained above, be dimensioned such that they are on the one hand at least greater than the opposing forces acting in the blocking position and on the other hand at least so large that the locking lever 1 is at least as far pivoted about the axis of rotation 10 that the latch 13 of the locking lever 4 is no longer with the locking edge 9 of the second lever arm 7 of the safety lever 1 is engaged and thus released.
  • the force exerted by the electromagnet 3 attraction force on the second lever arm 7 is so large that it is pivoted so far until it rests against the stop contact 18 of the electromagnet 3.
  • the first lever arm 6 After completion of the energization of the electromagnet 3 and thus lack of force from the electromagnet 3 to the second lever arm 7, the first lever arm 6 is rotated back into the locked position to the top 8 of the biased compression spring 11 and the resulting restoring moment due to the force Lever arm 6, the switch contact 17 of the microswitch 2 is actuated. The microswitch then reports the blocking position.
  • the electromagnet 3 may be magnetically biased by means of a permanent magnet (not shown) such that its force action is activated in a non-energized state. In this way you get a quiescent current door opener.
  • FIGS. 1 and 2 vertically oriented door openers can be installed independently of location, so for example horizontally.
  • Another embodiment, not shown, is to provide a permanent magnet which is in operative connection with the first lever arm 6. It has the function of a holding magnet, so that the safety lever 1 is held in its locked position when the solenoid 3 is de-energized.
