Definitions

  • the invention relates to a door opener.
  • Door openers are known. They each comprise a pivoting latch which, in the locking position, engages with a corresponding part of mainly a door leaf, such as a latch, in such a way that opening of the door leaf is prevented. If the pivot latch is released with respect to its pivoting movement, it can pivot away from the latch in the direction of the unlocking position in the event of a door-opening attempt. As a result, the corresponding part of the door leaf can be moved past the pivoting latch and thus the relevant door leaf can be opened.
  • a locking lever is pivotally mounted on and pivoted away from the pivotal latch. Pivot and locking lever abut each other via mutually corresponding surfaces.
  • the DE 25 22 973 A1 proposes, firstly, to use a leaf spring which is attached at one end to a side facing away from the locking lever of a designated as a hinged armature locking anchor, and the other end is free. This free end is in blocking position of the locking anchor on a latch.
  • Blocking position means that the locking arm prevents pivoting of the locking lever from a blocking position in the unlocked position.
  • Locking position means that the locking lever in this position prevents pivoting of the pivoting latch from a locking position in the unlocked position.
  • Locking position means that the pivoting latch is prevented from pivoting in one direction, which would cause unlocking of the corresponding door leaf and thus make it possible to open it.
  • the object of the invention is to at least reduce the disadvantages of the prior art.
  • an electric door opener that is to say a door opener which is electrically actuated.
  • the door opener is known to have a pivotal latch which is pivotally mounted between the unlocked position and the locking position.
  • the pivot latch is adapted to be brought into locking position with a corresponding part of a located in the closed position rotary wing in such a way that the rotary wing is prevented from opening.
  • the corresponding part is the case of a door lock.
  • the door lock is mounted in a known manner on or in here designed as a door sash.
  • the pivot latch is further configured, are pivoted in unlocking usually by opening the rotary wing out of engagement with the corresponding part, so that the opening movement of the rotary wing is released.
  • the rotary wing can therefore be opened.
  • the door opener also has a locking lever, which is also mounted in a known manner about a first axis on the pivot latch in the locked position and away from it in the unlocked position. In the blocking position, the locking lever prevents the pivoting latch from pivoting out of the locking position toward the unlocking position.
  • the door opener comprises a locking anchor, which is also mounted in a known manner about a second axis on the locking lever in the blocking position and away from it in the release position. In blocking position prevents the Sperranker pivoting of the locking lever from the locked position in the unlocked position.
  • the door opener on an electromagnet, which is adapted, when actuated, so when energized, the barrier armor electromagnetically in the direction of release position or in an opposite direction to urge or move.
  • the door opener is designed so that the locking lever is prevented in blocking position its blocking position with respect to the other door opener in a further pivoting of the locking lever from the locked position out towards the pivot latch and back again.
  • a shaking on the door could indeed cause the locking lever is repeatedly repeatedly pivoted from its locked position in the direction of pivoting latch and back again.
  • this does not affect the position of the locking anchor, there is no danger that the locking armor could be "shaken" from its blocking position both in the direction of the release position and in the opposite direction. This increases the safety in the operation of the door opener without increasing the energy required to open the door leaf.
  • the aforementioned design of the door opener is carried out in such a way that the locking armature is designed so that it is in the blocking position outside a defined by the Rothverschwenken Rothverschwenk Schemes the locking lever D. h. the locking lever is unable to transmit its movement to the locking armor in any way directly or indirectly.
  • This solution has the advantage that no additional parts are required to ensure the retention of the blocking position corresponding position of the locking armature with respect to the other door opener.
  • the door opener as a design according to the invention further comprises a stop which limits a pivoting of the locking armature in the blocking position.
  • the stop is arranged so that it is outside the entire pivoting range of the locking lever. Ie. the stop does not affect the pivoting of the locking lever.
  • this design of the door opener thus defines the stop and not the locking lever, the blocking position of the locking armature or its pivoting from its release position out in the blocking position.
  • the aforementioned design of the door opener be such that a the locking lever facing surface of the locking armature on which the locking lever passes in its Rothverschwenken, at least partially follows a circumferential line of a circle whose center is a point on the first axis. This first axis runs perpendicular to a surface defined by the circle. Since the locking lever is pivoted about the same, first axis, it can no longer happen here alone due to the design of this surface of the locking armature that the locking armature is moved by the locking lever.
  • the design of the door opener may be such that the aforementioned surface of the locking armature is formed so that the locking lever rests in the locking position and along its further pivoting in the direction of the pivotal latch on the following section of the circumference of the locking armature.
  • the locking lever serves as a blocking position end stop of the locking armature.
  • the section of this surface following the circumference effectively prevents the locking armature from being moved out of its actual locking position in the direction of the locking lever.
  • the locking armature is biased towards locking position.
  • This has the advantage that the locking armor is urged in the direction of blocking position solely on account of the prestress acting on it. If the bias is realized by one or more mechanical elements such as return springs, no electrical energy is required to urge the locking armature in the blocking position. Since the locking armor can not leave his blocking position, the bias can be designed as in known door openers that have no "vibration protection". They can also, as explained in more detail later, be made weaker. Ie. the device that realizes this bias can be designed or even reduced in terms of the applied biasing force and thus also in terms of their dimensions in the usual manner.
  • This solution also allows the use of a bistable electromagnet, which is energized only when the Speranker is to change position, and is able to magnetically located in the release or blocking position Speranker without energization to hold against any pretensioning forces.
  • This solution is particularly energy-saving, so that the use of rechargeable batteries can be considered as energy supply of the door opener.
  • the locking armor or the locking lever can move on a side facing the locking lever or the locking armature, at or with which the locking lever passes when it is pivoted further
  • the bias is so great that the Physicssabschnift along the defined by the Rothverschwenken Rothverschwenk Schemes the locking lever abuts on Speranker or locking lever
  • the bias is also so low that the guide portion is not able, the locking armature away from the locking lever so towards release position pushing. A pivoting of the locking armature due to the prestressed bearing guide section in the direction of the release position is thus prevented.
  • This solution has the advantage that the aforementioned restoring elements can be dispensed with in the case of the section of the locking armature following a circular line. Another advantage is that in the case of biased storage of the locking anchor in the direction of blocking position, the aforementioned surface must follow no circular line. In addition, bumps or other undesirable geometric shapes in the thus serving as a running surface bearing surface of the locking lever or locking lever can be compensated. Apart from that, it is also possible to compensate for inaccuracies in the positioning of the locking armature with respect to the locking lever to a certain extent, for example, due to different thermal expansion behavior or to ensure a certain distance between the locking armature and locking lever. Overall, this solution improves safety during operation.
  • a door system comprises a revolving door wing as the aforementioned rotary wing. Furthermore, it comprises a door lock mounted on or in the revolving door leaf with a latch as the aforementioned corresponding part. Finally, the door system includes one of the aforementioned door opener. Ie. Door opener and door lock are arranged in the closed position of the revolving door wing to each other so that the pivot latch in the locked position on the latch prevents the revolving door from opening.
  • FIG. 1 shows an electric door opener 1 according to a first embodiment of the invention, and only the essential parts for explaining the invention. It is clear that further parts such as power supply, bus connection, control, housing cover, etc. may be provided to operate the door opener 1 in the desired manner.
  • the door opener 1 is basically constructed like any known electric door opener. Ie. it has a housing 10 in which substantially all components of the door opener 1 are arranged. This includes one Pivot trap 20 which is pivotally mounted about an unspecified, parallel to the longitudinal extent of the pivotal latch 20 extending axis.
  • the pivot latch 20 has on a side facing away from a locking lever 30 a locking portion 21 in the form of a latch angle.
  • a trap of a corresponding lock is received in a receiving space 5 formed between the trap angle and a rear wall 11, for example.
  • the pivot latch 20 is preferably biased in this position in a likewise known manner.
  • the pivot latch 20 When opening the rotary vane, the pivot latch 20, if not locked, in the opening direction, so here to the front of the door opener 1 without cover shown, pivoted so far that the case can be moved past the pivot latch 20.
  • the pivot latch 20 has on its side facing away from the locking portion 21 side a projection as a locking portion 22 which cooperates with a locking portion 31 of the locking lever 30 in a likewise known manner.
  • the blocking section 31 is formed by means of a surface extending in the direction of the pivoting catch 20 and the rear wall 11 of the housing 10. Thus, this area extends obliquely to the rear wall 11.
  • the pivotal latch 20 is therefore pressed against the locking portion 31 with its locking portion 22 in the aforementioned case in the aforementioned case with mechanical loading by the aforementioned case. If the locking lever 30 is not blocked, the pivoting latch 20 can push the locking lever 30 over its locking portion 22 by sliding along the inclined surface of the locking portion 31 away. Thereby, the locking portion 22 is moved past the locking portion 31, and the pivot latch 20 can release the case, so the associated rotary wing can be opened.
  • the locking lever 30 is freely rotatably or pivotably received in the housing 10 via a pivot axis 34 arranged in a bearing block 12 of the housing 10 or formed thereon.
  • a snap ring 2 prevents the locking lever 30 from being able to detach from the pivot axis 34.
  • the locking lever 30 is biased by a return spring 3 in the direction of locking position.
  • a free end of the locking lever 30 facing away from the pivot axis 34 forms a blocking section 32 which cooperates in a known manner with a corresponding blocking section 41 of a locking armature 40.
  • the locking armature 40 is freely rotatable or pivotably received in the housing 10 via a pivot axis 44 arranged on the housing 10 or formed thereon.
  • a snap ring 2 again prevents the locking armature 40 from becoming detached from the pivot axis 44.
  • the blocking portion 41 is formed by means of a direction of locking lever 30 facing projection.
  • the locking arm 40 is shown in blocking position and causes the locking lever 30 can only be pivoted so far in the direction blocking portion 41 until the Blocklerabroughe 32, 41 abut each other.
  • the locking portion 22 of the pivotal latch 20 seen in the pivoting direction for opening the aforementioned rotary wing, on the locking portion 31 of the locking lever 30.
  • the locking armature 40 is biased by means of two return springs 4 in the blocking position. The return springs 4 press against a facing side or surface 43 of the locking armature 40th
  • the blocking sections 32, 41 abut one another in the blocking position.
  • the seals put the respectively associated door in the closed position under bias or in such a position that the aforementioned case urges the pivotal latch 20 of the corresponding door opener 1 in the opening direction. If the door opener 1 used in door systems without such seals, would account for this type of bias.
  • the door opener 1 can be used in both types of door systems, is at the door opener 1 for door systems without such seals a Play the locking lever 30 provided in the aforementioned blocking position. Ie. the locking lever 30 can be pivoted to a certain extent between the pivotal latch 20 and blocking portion 41 of the locking armature 40 when locking the pivoting latch 20 and blocking locking armature 40. Ie. the blocking portions 32, 41 are as shown in FIG FIG. 1a shown in blocking position not necessarily to each other. As a result, the aforementioned shaking on the pivot latch 20 in particular in this type of door systems is possible. Another reason for this game is due to the fact that the blocking sections 32, 41 otherwise would not easily be able to move past one another in the event of intentional pivoting of the locking armature 40. Last but not least, design-related tolerances can be compensated.
  • the locking armature 40 is specially designed. As in FIG. 1b is shown, a surface 42 along which the blocking portion 32 of the locking lever 30 is moved when jogging, not flat but curved.
  • the curvature corresponds to a perimeter of a circle whose radius r (indicated by the dotted-dashed double arrow) is substantially the distance of the farthest point of the locking lever 30 remote from a center M of the pivot axis 34 or is slightly larger.
  • r indicated by the dotted-dashed double arrow
  • the locking armature 40 can not change its position in the direction of the locking lever 30 or in the direction of associated return springs 4 due to the described curved shape of the surface 42. Ie. the shaking, even if repeated, can lead to no or only such a slight pivoting of the Sperrankers 40 that this can not aufschaukeln and thus the blocking of the locking lever 30 by the Sperranker 40 is certainly not repealed.
  • FIG. 1b a solenoid 50 can be seen, which is about a plunger 51 in a position to pivot the locking armature 40 from the blocking position against the action of the return springs 4 in the direction of the release position.
  • the blocking lever 30 can now be pivoted away from the blocking latch 41, away from the pivoting latch 20, in the unlocking position.
  • Figure 1c shows the door opener 1 of FIG. 1b in enlarged section. It can be clearly seen that the projection 33 has a rounded tip with which the locking lever 30 during pivoting from the blocking position shown to the left, ie in the direction of the pivot latch 20, along the surface 42 of the locking armature 40 along. The rounding serves to reduce the resulting friction and reduce the risk of tilting.
  • FIG. 2 shows a door opener 1 according to a second embodiment of the invention and in enlarged detail and without locking portion 21.
  • This embodiment differs from the first embodiment mainly in the design and arrangement of the locking anchor 40th
  • the surface 42 is exemplarily not arcuate. Rather, it forms the bottom of a well known from conventional door openers 1 recess 45th D. h. the surface 42 is formed so that the locking armature 40 is pressed in the case of the above fast swinging back and forth of the locking lever 30 in the direction of the pivotal latch 20 in the direction of locking lever 30 and the pivoting back of the Locking lever 30 is pushed back towards the blocking position slightly further towards springs 4.
  • the locking arm 40 can rock so that it moves away from its blocking position in the direction of the release position and thus the locking lever 30 is released.
  • a fixedly arranged in the housing 10 stop 13 is provided which limits the pivoting of the locking armature 40 in the direction of locking lever 30. Ie. the stop 13 defines the blocking position of the locking anchor 40.
  • the stop 13 is arranged so that the locking lever 30 neither in the in FIG. 2 Blocking position shown still in another position in which the locking lever 30 is further pivoted in the direction of the pivotal latch 20, is able to stand out from the barrier armature 40 from the stop 13 in the direction of springs 4. Either the stop 13 ensures that the surface 42 always has a distance from the locking lever 30 or can be touched by the locking lever 30 at most. Ie. also in this embodiment, the aforementioned rocking is prevented.
  • the stop 13 may be formed on the housing rear wall 11 or formed on it, for example by means of a screwed into the rear wall 11 screw.
  • FIG. 3a shows a door opener 1 according to a third embodiment of the invention also without locking portion 21.
  • the stop 13 is missing again by way of example.
  • the surface 42 follows by way of example the aforementioned circumferential line of a circle with radius r, which is slightly larger here as the distance of the Schenkstoffticians M not shown here of the locking lever 30 from the farthest point of the locking lever 30th
  • the locking armature 30 On a side of the blocking section 41 facing the locking armature 40, the locking armature 30 has a guide section 60.
  • This comprises a biased towards Sperranker 40 mounted roller 61.
  • the bias is such that the roller 61 is indeed urged against the barrier armature 40, but is not able to move it away from the pivot lever 30 in the direction of release position.
  • the roller 61 is thus pressed with a force against the Sperranker 40, which ensures that the distance between Speranker 40 and locking lever 30 is not or only slightly so that the aforementioned rocking can not occur.
  • the roller 61 is received translationally guided via an axis 62 or shaft in a corresponding slot 35 of the locking lever 30.
  • the elongated hole 35 preferably extends along a line which intersects both the Schenk center M of the locking lever 30 and the surface 42 of the locking armature 40. Ie. the line corresponds to the radius distance with respect to the surface 42.
  • the springs 4 are omitted here by way of example. This is possible when the door opener 1 is installed in the position shown. The weight of the Sperranker 40 is sufficient to take the blocking position.
  • FIG. 3b shows the locking lever 30 and its blocking portion 32 in section and substantially from the left in FIG. 3a .
  • a non-continuous recess 36 which is open in the direction of the locking armature 40, which is not shown here, is formed.
  • a biasing element in the form of a spring 65 is inserted.
  • an example of a U-shaped cross-section holder 64 is supported with its bottom and also received in the recess 36.

  • a magnetic operative connection between locking armature 40 and locking lever 30 Ie. one of the blocking sections 32, 43 or one of the mutually facing areas or surfaces (such as the surface 42) are formed from magnetizable material or have such. The other, thus corresponding blocking portion 43, 32 or the other or the other facing area or surface is accordingly formed from permanent magnetic material or has such. This makes it possible for the locking lever 30, the locking armature 40 safely in Toward the blocking position, which makes the aforementioned rocking of the barrier anchor 40 at least difficult.
  • the stop 13 may be provided in all embodiments.
  • the stop 13 may be arranged so that it is outside the entire pivoting range of the locking lever 30, so its pivoting can affect anywhere.
