Definitions

  • the invention relates to an unlocking device for unlocking doors, in particular emergency exit and / or escape doors, with an on the door leaf to be mounted, elongated housing-like receptacle and arranged in the receptacle, transversely to the longitudinal direction of the recording movable pressure bar, recording and pressure bar Enclose a closed interior and in the interior transmission means for converting a relative movement between the pressure bar and the receptacle are arranged in a rotational movement of a pin for unlocking the door latch.
  • Such unlocking devices are well known, they are often referred to in professional language as "panic bars”.
  • Panic bars are now very popular among architects and builders. These have the particular advantage that they are unlocked with a force acting in the direction of the door leaf of the escape or emergency exit door force and require no movement transverse to the direction of escape. Thus, the corresponding emergency exit or escape door is also opened when a stream of fleeing, possibly in panic persons is pressed only against the equipped with such unlocking door.
  • door guard for example, in the EP 1 365 089 revealed device.
  • a body held in a rail in a basic position body is disposed below the door handle or the door handle, which falls upon actuation of the door handle and associated opening of the door from the basic position in an alarm position vertically down and outputs an alarm signal.
  • Such a solution is theoretically still possible for free-standing panic bars, which are also moved downwards in the direction of the door leaf during an opening movement, but are no longer practicable in the case of the aforementioned variants of a release device with a compact construction.
  • a driver plate or the like Is attached to the pressure bar, behind which is a lever-like, attached to a main body of an alarm device arm. Upon actuation of the pressure bar, the arm is detached from the housing and triggered an alarm in the housing.
  • the essential idea and aspect of the invention resides in the fact that it makes use of an installation space, as it were, inside the unlocking device between the elements receiving and pressure bar, to accommodate an alarm device with its essential elements, the sensor device for monitoring an actuation of the pressure bar and alarm output unit for dispensing an alarm signal.
  • This latter alarm signal can either consist in an electrical signal, which is forwarded to a monitoring center and processed there, for example, but it can in particular also in an optical alarm output, such as a flashing lamp or LED, but also in an audible alarm signal as well as any combination of said options exist.
  • the inventive solution to arrange the alarm device inside the unlocking in a limited essentially by the recording and the pressure bar cavity not only requires a particularly compact design, which does not differ from the outside or only slightly different from conventional unlocking devices of this type, it offers In addition, a good protection and a fuse for the alarm device. Since the receptacle and the pressure bar are usually formed from metal or another durable material, the alarm device arranged in the interior of the unlocking device there is reliably protected against external influences, in particular vandalism.
  • a push rod which is movably mounted in the receptacle in the longitudinal direction.
  • This push rod can thereby directly or via intermediate force transmission elements, e.g. acting on a arranged in a rotatable nut for moving the case pin and put this in a longitudinal displacement of the push rod in a rotational movement.
  • the motion coupling between the pressure beam and the push rod can be e.g. take place via hinge bars, which are each connected at one of its ends articulated to the pressure bar, with another of its ends hinged to the push rod.
  • the sensor device may, for example, comprise a microswitch, which moves due to a relative movement between the pressure bar and the receptacle or an element of the transmission means and the recording from an on position to a switched-off position or operated in the reverse manner.
  • a microswitch which moves due to a relative movement between the pressure bar and the receptacle or an element of the transmission means and the recording from an on position to a switched-off position or operated in the reverse manner.
  • the sensor device may also have a first sensor element arranged stationary relative to the receptacle and at least one second sensor element arranged on the pressure bar or an element of the transmission means comprise, wherein these sensor elements cooperate to detect a relative movement between the first and the second sensor element.
  • Such sensor elements may in particular also be formed by a pairing of at least one REED contact and at least one magnetic element. REED contacts represent a cost-effective and very reliable form of a non-contact and thus trouble-prone sensor.
  • the sensor device is set up so that it not only triggers an alarm upon actuation of the pressure bar, but is able to distinguish between at least two positions relative to each other shifted pressure bar and recording, namely a Voralarm ein in which the pressure bar is indeed operated, but the door not yet unlocked, and a main alarm position when the door is unlocked.
  • a Voralarm ein in which the pressure bar is indeed operated, but the door not yet unlocked
  • a main alarm position when the door is unlocked.
  • the acknowledgment switch may be e.g. a key switch or a button or the like located behind a cover plate accessible with a key or a code, so that it can only be operated by authorized personnel and the main alarm can be reset in this way.
  • the unlocking device can advantageously also contain a locking element which holds the pressure bar in a not suitable for unlocking the door normal position and releases it only after an active unlocking.
  • a locking element which holds the pressure bar in a not suitable for unlocking the door normal position and releases it only after an active unlocking.
  • Such locking elements are often required by operators of emergency exit and panic doors in publicly accessible buildings to provide an additional barrier to unauthorized operation.
  • Such a locking element can be realized, for example, as shown in claim 11 by an electromagnet and a ferromagnetic counterpart, of which in each case one element on the pressure bar or one element of the transmission means and the other element are fixedly arranged and fixed to the receptacle.
  • the release or release of the locking element in particular so the switching off of the electromagnet, carried out by pressing the pressure bar.
  • FIG. 1 is first shown in a highly schematic representation of an unlocking device according to the invention in a three-dimensional manner and generally designated by the reference numeral 1.
  • the unlocking device 1 is a total formed like a bar and elongated and contains as essential parts an elongated receptacle 2 and a used in the receptacle 2 and relative to this transversely to the longitudinal direction movable pressure bar 3.
  • Both the receptacle 2 and the pressure bar 3 are formed here as U-profiles.
  • the pressure bar 3 is inserted into the receptacle 2, that the two U-profiles are directed towards each other with their legs bounding the opening of the U and so inside of the unlocking an interior or cavity is formed.
  • FIG. 1 Last is in the FIG. 1 still indicated that the pressure bar 3, starting from a normal position N, as shown in FIG. 1 is shown, can be depressed first up to a release position A and then continue to actually open the door on this release position A addition.
  • FIG. 1 there is an in FIG. 1 Not shown, arranged inside the imaged between the receptacle 2 and the pressure bar 3 interior alarm device a pre-alarm, as soon as the pressure bar 3 is deflected from the normal position N up to the maximum release position A. If the pressure bar 3 is depressed further on the release position A, so the alarm device outputs a main alarm.
  • pressure bar 3 and end caps 4 are in the embodiment shown here preferably made of metal, in particular stainless steel.
  • FIG. 2 is a section of in FIG. 1 Below this sound outlet opening 6, an acoustic alarm is arranged, the sound both in the pre-alarm and in the main alarm, an audible alarm signal, eg. A whistling sound leaves.
  • an audible alarm signal eg. A whistling sound leaves.
  • FIG. 3 is the in FIG. 2 shown portion of the unlocking device 1 shown, this time with partially cut away with pressure bar 3.
  • the door lock T is indicated by a door, on whose sheet the unlocking device 1 is attached.
  • Below the cut away pressure beam 3 is here in particular a longitudinal direction of the receptacle 2 movable push rod 7 can be seen, which takes place in this section relative to the recording by the interaction of formed in the push rod 7 slots 8 defined on the receptacle 2 pins 9.
  • left end of the push rod 7 opens into a fork 10 which engages around a nut 11 connected to the unlocking mechanism of the door latch.
  • a projection 12 is arranged, abuts against the fork 10 and rotated over the indicated at a double arrow by the forward or backward movement of the push rod, the nut 11 and thus the case of the door is unlocked.
  • the acoustic alarm which is located in this area below the sound outlet opening 6.
  • FIG. 4 is finally seen from the illustration in FIG. 2 further right-most portion of the unlocking device 1 shown, the essential parts of the arranged in the interior between recording 2 and pressure bar 3 alarm device contains and other components to be described later.
  • the permanent magnet 17 opposite two REED contacts 18,19 are arranged stationary to the receptacle 2 and connected to the latter, which together with the permanent magnet 17 form a sensor device.
  • two REED contacts 18 and 19 are provided here, which serve to detect the different positions of the unlocking device 1. If the permanent magnet 17 is the first REED contact 18 opposite, so the pressure bar 3 is in the normal position N, there is no alarm.
  • the pressure bar 3 If the pressure bar 3 is pressed, the push rod 7 moves in FIG. 4 to the left, the permanent magnet 17 leaves its position relative to the REED contact 18, which then emits a signal to an alarm output unit.
  • This signal is equivalent to the pre-alarm, the signal output unit outputs a corresponding alarm signal in an optical and acoustic manner, which ends when the pressure bar 3 is released and returns to its normal position.
  • the pressure bar 3 is further depressed, then the permanent magnet 17 against the REED contact 19 and triggers another signal that triggers the main alarm.
  • This main alarm is permanently audibly and visually displayed by the alarm output unit, it can only be terminated by pressing an acknowledgment switch, which is no longer shown here.
  • the positions of the REED contacts 18 and 19 and the permanent magnet 17 are adjusted so that when triggering the REED contact 19, the fork 10 (see FIG. Fig. 3 ) is applied directly to the projection 12 of the nut 11 so that upon further actuation of the pressure bar 3, an opening of the door takes place.
  • FIG. 4 is further indicated by dashed lines that in this area a further connecting bolt 13 is arranged for transmitting the downward movement of the pressure bar 3 in a longitudinal movement of the push rod 7.
  • the push rod 7 at its end opposite the fork 10 has an angled end 22, which faces an electromagnet 21.
  • This electromagnet 21 and the angled end 22 are optional features, the electromagnet 21 as an additional locking element hold the push rod 7 and thus the pressure bar 3 in the normal position N and are turned off only when activated, and this can release.
  • This active release is preferably also by means of pressing down the pressure bar 3, to continue to ensure the required single-handed operation of the emergency exit or escape door.
  • connection terminal 20 can also be seen, via which the supply and signal lines for the REED contacts as well as for further illustrated LEDs 23 and 24, which in particular serve to output the optical alarm signal, can be connected.
  • the supply of the alarm device in the interior of the unlocking device 1 according to the invention is preferably carried out via battery, wherein the battery is also arranged in the interior space between receptacle 2 and pressure bar 3. It makes sense that the alarm device is so interconnected and built that it emits a warning signal when battery power is decreasing.
  • the above-mentioned acknowledgment switch can either be accessible from the outside key switch or a arranged below one of the end caps 4 pushbutton, the relevant end cap 4 then also conveniently locked with a key or the like. Secure locking element and can only be opened by authorized personnel.
