Definitions

  • the invention relates to a door guard for monitoring an emergency exit door with a door leaf and a releasable locking device, wherein the emergency exit door can be opened via a manually pivotable about a Whoelementschwenkachse control element comprising a housing arranged on the door, a sensor device for detecting the pivot position of the control element in a defined pivoting range is formed and a control unit, which is designed in such a way that it switches the door guard between a monitoring state, a pre-alarm and an alarm state depending on the sensed by the sensor device pivot position of the control element.
  • the invention further relates to an emergency exit door with a door leaf, an actuating device and a door guard.
  • gatekeeper is generally understood to mean devices for monitoring emergency exit doors, which are designed in such a way that they detect the operation of an emergency exit door, indicate the opening attempt to the user by, for example, optical and / or acoustic means and trigger an alarm through an opening of the emergency exit door
  • Generic door guards are often below the pivoting control element of the emergency exit door, in particular a door handle or a panic bar, arranged directly on the door leaf of the emergency exit door.
  • two functional principles of the known door guards can be distinguished.
  • the DE 20 2008 000 326 U1 a device for securing emergency exits, in which a vertically displaceable housing is arranged below the handle designed as a door control element.
  • the housing When the doorknob is actuated, the housing is displaced downwards by the door handle striking against the housing. Depending on the pivoting of the control element thus changes the degree of displacement of the housing, wherein, depending on the degree of displacement of the housing first a pre-alarm and then, upon continuation of the shifting process, a main alarm is triggered. Will the operation of the Operating element, however, interrupted before the main alarm, the door latch and the door guard automatically return to their initial states. Alternatively it is from the DE 81 18 314 U1 known to form the door guard as a blocking device against the control of the emergency exit door. In this embodiment, the housing of the door guard blocked the pivoting of the control element, specifically the doorknob, in an attempt to open the control.
  • the DE 203 15 136 U1 Finally, also discloses a door guard with a pivoting the door handle blocking housing, which connects the two above principles of operation together.
  • the case of the doorkeeper of DE 203 15 136 U1 has in the contact area to the control element of the emergency exit door on a sliding bevel against which abuts the operating element when actuated.
  • the operating element slides along the sliding bevel, wherein the sliding bevel is formed in such a way that it converts a movement of the operating element in the opening direction in a pivoting of the door guard from the pivoting path of the operating element out. Also, this door guard must thus be swung out with its housing from the pivoting of the control element to allow opening of the emergency exit door.
  • Generic door guards are thus based on the idea to counteract the improper opening of an emergency exit door and at the same time to ensure the ⁇ ffenley the emergency exit door in an emergency.
  • For generic door guards usually the three operating states monitoring state, pre-alarm state and alarm state are provided. In the monitored state, the emergency exit door is closed and the door guard monitors whether an attempt to open the emergency exit door is made. If the housing of the door guard moved out of this monitoring position (according to one of the above-mentioned principles of operation known door guard), this switches first, depending on the extent of pivoting of the door guard in a pre-alarm state.
  • the pre-alarm state is characterized by the fact that the emergency exit door is still closed and a sensible pre-alarm, for example, acoustically and / or visually, is activated.
  • the pre-alarm signals to the user that the door is an emergency exit door that is not intended for routine through-traffic. This is intended in particular to prevent improper or unintentional opening of the emergency exit door. If the user interrupts the opening attempt in the pre-alarm state, the door guard returns to the monitoring state back. If, however, the door guard is moved past the pre-alarm state, the door guard switches from the pre-alarm to the alarm state.
  • the emergency exit door is now openable and walkable. However, a cancellation of the alarm state is no longer readily possible and requires rather special measures, such as the cancellation of the alarm by authorized personnel, for example by pressing a key switch, entering a code, etc.
  • the essential idea of the invention is to design the door guard in such a way that it is possible to dispense with pivoting the entire door guard housing for detecting the actuation of the operating element.
  • the control is pivotally mounted on the emergency exit door and typically has a handle for manual operation.
  • the control element according to the invention is in particular a door handle or a panic bar.
  • Under the housing of the door guard that is possibly also multi-part constructed and preferably cover-like designed component to understand the essential components of the door guard, such as beispeirati an electronic control unit, an audible alarm device, etc., after shields the outside.
  • the invention proposes a completely different way and proposes to solve the problem a relative to the door leaf of the emergency exit door fixed housing before (and not just a relative to the door leaf movable housing).
  • the sensor device comprises a pivoting lever which protrudes beyond the housing and is hinged about a pivoting lever axis and which is designed in such a manner that it is in operative connection with the operating element in the installed state of the doorkeeper in such a way that in a fixed pivoting range with a pivoting of the Operating element also pivoting of the pivot lever takes place.
  • a pivot lever is provided, which is pivotally mounted on the door guard side or on the part of the door guard, in particular on or in the housing of the door guard, projecting beyond the housing for detecting a control movement in the defined pivoting range of the control element or in the assembled state at least one Subarea protrudes into the pivoting path of the operating element.
  • pivotable mounting of the pivot lever on the fixed housing is present in the sense that the pivot lever does not have to be physically connected directly to the housing itself. Rather, the pivot lever is mounted on the door guard in such a manner that it projects at least partially beyond the outer surface of the housing and is pivotable relative to the housing.
  • the pivot lever may for example be directly connected to the housing, stored inside the housing and led out of the housing or stored separately and connected by suitable means to the housing.
  • the pivot lever is further at least in a predetermined region of the pivoting path of the operating element in operative connection with the operating element or the pivot lever is formed in such a way that it can at least partially detect the pivoting movement of the operating element in the installed state .
  • an operative connection is concretely a functional connection between the control element and the pivot lever to understand, which is designed in such a way that it converts a pivoting of the control element in a pivoting of the pivot lever, which in turn is used to detect a movement of the control by the door guard , If the operating element is moved or pivoted, moved or pivoted at least in the defined area thus also the pivot lever.
  • the pivoting lever and the operating element can be permanently in functional communication with one another, as is possible inter alia via a corresponding joint or further articulation elements.
  • the operative connection between the operating element and the pivoting lever can also be designed in such a way that it exists only over a certain part of the pivoting movement of the operating element. It is crucial that the operative connection between the control element and the pivot lever is made in an operation of the control element in good time before unlocking the emergency exit door to timely display a pre-alarm and to alert the user before a door unlocking the emergency exit door.
  • the pivot lever is in operative connection with the handle of the operating element at least in the fixed pivoting range. In this way, for example, no additional components on the part of the control element is required and a special adjustment of the control element is not required.
  • the door guard according to the invention is correspondingly versatile applicable.
  • the pivoting lever is also mounted on the sensor device in such a way that it can be pivoted toward the door leaf.
  • the invention includes a variety of different storage options with different pivoting movements of the pivot lever.
  • This relates in particular to bearings in which the pivot lever, for example, is movable parallel to the door leaf or the pivot plane of the pivot lever runs parallel to the door leaf surface.
  • Further bearing alternatives are, for example, arrangements in which the pivoting lever is mounted in such a way that, when actuated by the operating element, it moves in parallel or in opposite directions to the pivoting movement of the operating element, in particular of the door handle.
  • middle positions between a parallel or counter-rotating and pivoting towards the door leaf storage are possible.
  • pivoting of the pivot lever to the door leaf is particularly advantageous.
  • the pivoting plane of the pivoting lever thus extends in this embodiment substantially orthogonal to the door leaf surface.
  • This arrangement is especially favorable for reasons of space technology, since, upon actuation of the control element and an associated pivoting of the pivot lever in an emergency situation, this is pivoted toward the door leaf and thus virtually "out of the way".
  • such an arrangement is particularly well to detect the pivoting of a designed as a door handle and especially as a panic control element.
  • Another preferred alternative is the arrangement of the pivot lever in the Way that its pivot plane is parallel to the door leaf surface.
  • This embodiment is particularly suitable in combination with a door handle or a door handle as a control element, so that the pivot plane of the control element and the pivot plane of the pivot lever are the same or at least parallel.
  • the door guard can thus be arranged, for example, laterally next to the door handle, so that the pivot lever and the door handle pivot when actuated in different directions.
  • the door handle can be gripped almost without hindrance or the pivot lever of the door guard is not perceived as a hindering element.
  • the pivot plane of the control element and the pivot plane of the pivot lever thus at an angle and in particular orthogonal to each other.
  • the pivot plane designates the respective plane in which the pivoting movement of the operating element or of the pivoting lever runs.
  • a right angle to the corresponding pivot plane further extends the pivot axis of the control element or the pivot lever, which indicates the axis about which the pivoting movement takes place.
  • the control element pivot axis is thus, for example, that pivot axis about which the control element is pivoted during a manual operation.
  • the pivot lever of the door guard and the control of the emergency exit door are arranged in such a way to each other that the control element pivot axis and the pivot lever axis are skewed to each other, ie they do not intersect and they do not run parallel to each other.
  • This arrangement is particularly suitable when the control is designed as a doorknob.
  • the control element pivot axis and the pivot lever axis are arranged parallel to each other.
  • This embodiment is particularly suitable when using a panic bar as a control element. It is also preferred if the pivot lever is arranged parallel to the operating element and in particular to the longitudinal extension of the handle and parallel to this or, depending on the specific arrangement of the door guard to the control element, opposite to this pivotable.
  • the handle is part of a door handle. Swivel lever and door handle (and in particular the handle) are accordingly pivotable in almost the same pivot plane.
  • the door guard is then ideally arranged below the door handle in the area of the handle rosette and strikes from below in the longitudinal direction of the handle. By actuating the handle, the pivot lever then pivots downward almost parallel to the handle.
  • This embodiment is advantageous for safety reasons, since the pivot lever is not in the engagement area between the door leaf and handle more or pivots in this area. The pinching a finger between the door handle and pivot lever is thereby practically excluded, for example.
  • the door guard can also be arranged laterally next to the door handle, ie on the side opposite the handle rosette. As already mentioned above, in this case, the door handle and the pivoting lever pivot apart (for example, both down, but the pivot lever counterclockwise and the door handle in a clockwise direction). This arrangement is perceived by the operator as particularly hinderungs arthritis.
  • pivot lever and operating element via, for example, hinged or hinge-like connection mechanisms, as already mentioned above.
  • the spring loading is inventively formed in such a way that it pushes the pivot lever against the control element at least in the monitoring and pre-alarm state, so that it abuts against the operating element.
  • pivot lever strikes from below against the operating element.
  • the spring loading is formed in this embodiment in such a way that it pushes the pivot lever away from the door leaf from below against the operating element.
  • the pivot lever Upon actuation of the operating element, for example by pressing down the door handle, the pivot lever is pivoted in this embodiment, against its spring action in the direction of the door leaf.
  • the actuating force generally indicates the force which is exerted by the respective spring action on an element, in this case in particular on the pivoting lever and the operating element.
  • the control element is also spring-loaded in order to ensure pivoting back of the operating element into the starting position after an actuation.
  • the actuating force of the spring action of the pivot lever is selected relative to the spring action so that it is less than the spring action of the control element, in particular by a factor of 0.5 and especially by a factor of 0.1.
  • the operating comfort of the control element is particularly little influenced by the door guard according to the invention, since the additional to be applied by the user force for simultaneous adjustment of the pivot lever is relatively low for operating the equipped with a door guard control element.
  • this ensures that the pivot lever "runs" the operating element, which is particularly favorable for a reliable sensing of the position of the operating element.
  • the pivot lever is also preferably formed in such a way that it is pushed back to a predetermined maximum displacement by, for example, the spring back into the monitoring state and on exceeding this maximum adjustment angle but automatically in the alarm state to the housing or from the spring action is decoupled.
  • the adjustment angle is that angle which is formed between the current position of the pivot lever with respect to the pivot lever located in the monitoring state. The adjustment angle thus indicates, starting from the "initial state" or monitoring state of the pivot lever, by how many degrees the pivot lever has been pivoted about its pivot lever axis.
  • the pivoting lever has a spring action which pushes the pivoting lever back into its monitoring state
  • the maximum adjustment angle, before the pivoting lever is decoupled from the spring action is preferably between 25 ° and 65 °, in particular between 30 ° and 55 ° and especially between 35 ° and 45 °.
  • the door guard controls the switching from the monitoring to the pre-alarm and the alarm state solely as a function of the adjustment angle determined by the sensor device, in which case the control unit is designed in such a way that switching over once the maximum adjustment angle is exceeded takes place in the alarm state, which is subsequently maintained, even if the pivot lever pivoted back into the initial state by its spring action.
  • the maximum adjustment angle is preferably in the areas that have already been specified for the previous embodiment with decoupling of the spring application.
  • the door guard is further formed in such a way that it has an adjusting device with which the maximum adjustment angle or the release angle (the angle beyond which the alarm state is triggered) is adjustable.
  • the same may alternatively or additionally of course also be the case for the adjustment angle, from which the pre-alarm state is triggered.
  • the adjusting device is in other words designed in such a way that it allows an adaptation of the pivoting movement of the pivot lever to the respective installation conditions.
  • Corresponding adjusting devices may for example comprise a set screw, via which the corresponding switching points can be adjusted. An electronic adjustment with the help of the control unit is possible.
  • the latching is releasably formed and as soon as the desired positioning is obtained, the latching, for example via engagement of the pivot lever in a suitable transmission mechanism, can be restored.
  • the adjusting device is additionally secured in order to allow only authorized persons to adjust the pivoting lever.
  • the adjusting device may be designed, for example, in such a way that it can be activated or deactivated and deactivated or blocked via a key switch or a comparable device for proof of entitlement.
  • the pivot lever can also vary in its concrete design.
  • it is designed with two arms, wherein one arm is the contact arm between the bearing axis and the operating element, and the other arm of the sensor arm, via which the sensor device detects the pivoting of the operating element.
  • This sensor arm protrudes into the interior of the housing and is operatively connected to corresponding detection means.
  • the sensor arm and the contact arm are at an angle of 90 ° to 180 ° and in particular from 90 ° to 135 ° to each other.
  • Other arrangement variants between the pivot lever and the housing for example, also result from the fact that the pivot lever can be stored in different positions on the housing. For example, several bearing points may be present, in which the pivot lever can be suspended as needed.
  • the pivot lever is mounted on the housing side in a rotary head which is rotatable relative to the main body of the door guard housing, ideally in a plane perpendicular to the pivot plane of the pivot lever.
  • the rotary head of the pivot lever can thus in the desired direction relative to the housing, in which he protrudes from the housing or the entirety of the turret and main body of the housing, or be brought to the control, so that the position of the pivot lever of the installed door guard the control can be adjusted.
  • the installation is much easier, since first the door guard on the door leaf in its position relative to the control element is relatively coarse and a fine adjustment of the pivot lever then with the turret and, if available, with the above-mentioned adjusting device for the pivot lever is possible. An exact alignment of the housing when attaching the door guard on the door is therefore no longer necessary.
  • the axis of rotation of the rotary head preferably runs in the installed state of the door guard according to the invention in the vertical direction. In principle, it is possible to make the turret rotatable by 360 °.
  • the rotary head is preferably rotatable relative to the housing via a latching adjustment, wherein preferred latching steps are at 10 ° to 30 ° and in particular at 20 °.
  • the keyswitch simultaneously releases and locks several of the possibly existing adjusting devices (for example for the rotational position of the rotary head and for the pivoting position of the pivot lever in the monitored state), for example the adjusting device for the pivoting lever and / or further adjusting devices, for example for alarm sounds, Etc..
  • the housings of door guards are usually marked with signal colors strikingly colored.
  • this has the disadvantage that the marking in the dark, for example, by a power failure, etc., can no longer be perceived.
  • the invention circumvents this problem in that the pivot lever and / or the housing is at least partially made of a luminescent plastic or the housing and / or the pivot lever is at least partially provided with a luminescent coating, in particular plastic coating.
  • Such plastics or coatings "self-charge" by light radiation and emit visible light in the dark. This makes it possible, despite darkness, for example, due to a Power failure, the door guard according to the invention safe and easy to locate.
  • Luminescent plastics are usually thermoplastics in which special luminescent pigments are incorporated.
  • Typical thermoplastics are, for example, polyvinyl chloride (PVC), polypropylene (PP), polycarbonate (PC), etc.
  • a typical luminescent pigment is, for example, copper-doped zinc sulfide, strontium aluminate doped with a rare earth metal, in particular europium, etc.
  • door guards also have elaborately designed and complicated to manufacture and control display elements or displays that indicate visually perceptible, in which operating state, the door guard is currently, such as the monitoring state or the alarm state or the potential user to the functions of the door guard to draw attention.
  • These display elements are usually arranged on the housing and indicate, for example, by different colored lights, displays, etc. the operating state. Accordingly, such display elements require, for example, an electrical power supply, releases in the housing for appropriate lamps, etc., different colored bulbs and a control unit for controlling the bulbs, etc.
  • the invention proposes a completely new way in this context and allows the integration of a display element in one Door guard in a particularly simple and cost-effective manner.
  • the invention proposes to arrange a display element on the pivot lever, which is designed in such a way that it changes the display content in dependence on the adjustment angle of the pivot lever or in dependence on the viewing angle of the display element by the user.
  • a tilting image as a display element has been found to be particularly suitable.
  • Such tilting images are commonly referred to inter alia as a "wobbly image” or, more elaborately, as a "lenticular image”. Characteristic of such tilt images is that they depict at least two different images for a viewer depending on the viewing angle.
  • tilting images have, for example, a plurality of images which are divided into strips, wherein the strips of the images are each arranged alternately on a display surface.
  • the arrangement of the strips at different angles, with the strips of an image each arranged at the same angle to the display surface, or more for tilting images of known arrangement principles manages the viewer depending on the viewing angles of the perceives different pictures.

  • the tilting image is formed such that the viewing angle required for viewing the one image and the viewing angle required to view the other image have a difference between 60 ° to 120 °, in particular between 80 ° to 100 ° and especially 90 ° ,
  • the tilting image is preferably arranged on the externally visible outside of the pivot lever and indicates depending on the position of the pivot lever, for example, whether the door guard is in the monitoring state or in the alarm state.
  • the tilt images more than two images can always be displayed in a tilted image, depending on the viewing angle. It is thus also possible, for example, to integrate the intermediate pre-alarm state into the tilt image by means of a further image.
  • the display element is thus independent of an electrical power supply or comparable energy sources and is therefore particularly suitable for use with the door guard according to the invention.
  • Examples of informational content typically presented with the display element are "emergency exit” or “door locked” under the observer's viewpoint with the pan lever in the monitored state and “door unlocked” or “alarm” from the viewer's perspective with the panic lever in alarm ,
  • changing symbols can be represented by the tilt image, for example a stop sign and a passage character etc.

  • the handle such as a door handle or a panic bar
  • the door leaf surface In this way, a particularly narrow and aesthetically elegant design of the housing is possible because existing larger components inside the housing, such as Often a means for output of acoustic signals, a key switch, etc., can be spent out of the flattened area in the rest of the housing and in relation to the flattened portion of the housing.

  • the locking device is preferably designed in such a way that it deactivates the alarm device of the door guard in the activated state (ie in the state in which it detects the pivot lever), so that despite the pivoting of the pivot lever in the alarm position no alarm signal is output from the door guard ,
  • This allows a door secured by a door guard according to the invention to be used transitionally by fixing the pivot lever as a passage door.
  • this can be realized, for example, in such a way that the control unit is in the broadest sense designed in such a way that it switches off the alarm state or mutes the alarm when the locking device is activated.

  • a particularly reliable locking device comprises a cover which can be extended out of the housing and which is designed to lock the pivot lever. This cover can thus be pushed over the pivoted to the housing pivot lever, so that the pivot lever between the housing and the cover is located. The cover prevents in this way that the pivot lever returns to its monitoring position.
  • a switch contact is simultaneously actuated by the extension of the cover, via which a shutdown of the alarm function of the door guard is achieved.
  • a sleeve-like design of the cover has proven to be particularly favorable, since thus the pivot lever can be encompassed from all sides and a manipulative access to the detected pivot lever is made considerably more difficult in this way.

  • the local two-leaf emergency exit door 2 comprises two door leaves 3, wherein on each door leaf 3 designed as a panic control element 8 is arranged.
  • the basic design, arrangement and operation of a panic bar is known from the prior art. Such panic bars are pressed to the door leaf 3 to open the emergency exit door 2.
  • the pivot axis 5 of the panic bars 8 accordingly runs parallel to the pivot axis 14 of the pivot lever 13 of the door guard 1.
  • the arrangement of the door guard 1 in relation to the panic bar 8 may also vary as well. These are in Fig. 8 exemplified two arrangement alternatives. On the in Fig.
  • FIGS. 1 to 4 The operation and the various operating states of the door guard 1 are in the FIGS. 1 to 4 specified and apply to both in the FIGS. 6 to 8 illustrated embodiments.
  • Fig. 1 shows the door guard 1 off Fig. 6 from the one with I in Fig. 6 marked viewing direction.
  • the door guard 1 in Fig. 1 is in the monitoring state.
  • the spring action of the pivot lever 13 counteracts the Einschwenkides according to arrow A, so that the pivot lever 13 in FIG. 1 is pressed against the underside of the control element 8 (doorknob) and in the region of the handle abuts against this with its stop region 24 from below.
  • the consequences of an operation of the door handle or the operating element 8 are in the Figures 2 and 3 specified.
  • Fig. 2 shows the door guard 1 in the pre-alarm state.
  • VerschwenkungsTalk or adjustment angle which compared to Fig. 1 corresponds to an adjustment angle ⁇ of about 30 °
  • the sensed via the pivot lever 13 actuation of the door handle 8 causes the alarm device 12, an audible and / or visual alarm signal is output.
  • the displacement angle ⁇ is the pivot angle of the pivot lever 13 with respect to its initial position in the monitoring state ( Fig. 1 ) with unconfirmed operating element 8 (this reference position of the operating element 8 is in Fig. 2 indicated by the dashed line).
  • the door guard returns to the monitored state, driven by the spring action Fig.
  • the door guard 1 has a locking device 21, which comprises a cover 22 displaceably mounted in the housing 9 along the arrow C. Normally, the cover 22 is recessed inside the housing 9. If, however, the emergency exit door 2 can be accessible transitionally without triggering the alarm, the cover 22 can also be extended out of the housing 9 as part of the locking device 21, likewise via an actuation of the key switch 25.
  • the cover 22 is sleeve-like or is in the form of a cover sleeve and can on the pivoted pivot lever 13 from the housing 9 to in Fig.
  • the locking device 21 is further formed in such a manner that when the cover 22 is extended a in Fig. 4 not shown switch of the control unit 10 is actuated, which has a shutdown of the alarm function. As long as the cover 22 is extended and holds the pivot lever 13 in the pivoted position, the door guard is thus "muted” and sends neither visual nor audible alarms. The emergency exit door 2 can then be opened and closed as desired without an alarm being triggered by the door guard 1. Retracting the cover or a release of the determination of the pivot lever 13 with the locking device 21 is also possible only via an operation of the key switch 25.
  • the display element 16 is arranged on the outer or upper side of the pivot lever 13 and thus lies in the operating state between the handle of the operating element 8 and the surface of the door panel 3. In the in Fig. 5a shown position, the potential user thus considers the display element 16 from the direction indicated by the arrow D direction.
  • the display element 16 is formed as a tilting image 17. Accordingly, the display element 16 changes its displayed content as a function of the viewing angle ⁇ for the viewer.
  • the viewing angle ⁇ is the angle between the surface of the pivot lever 13 facing the viewer (in FIG Fig. 5c with the dashed line running parallel to this surface) and the viewing direction D of the observer.
  • the two contents contained in the tilting image 17 are denoted by reference numerals 18 and 19 in FIG FIG. 5c characterized in that only four inclined to the left surfaces with 18 and only four of the inclined surfaces 19 to the right are expressly marked with reference numerals.
  • the totality of the individual areas 18 or 19 each provide an image with corresponding content.
  • In the monitoring state according to FIG. 5a is the viewing angle ⁇ between the arrow D a from viewing direction D and with the parallel shifted dashed line (parallel to the viewer facing surface of the pivot lever 13 extends) 45 °.
  • the viewing angle D changes to the tilting image 17 of D a to D b (about 135 °) in Fig. 5c , Instead of the image formed by the individual display segments 19, the viewer now perceives the image represented by the display segments 18 in the pivoted-in state of the pivoting lever 13.
  • Fig. 9 relates to a further alternative arrangement of the door guard 1 relative to the control element 8, which is presently designed as a door handle.
  • the essential difference of this arrangement to the previous arrangements is that the housing 9 of the door guard 1 is arranged with a laterally to the pivot lever 13 side on the door leaf surface (not shown), compared to the arrangement in Fig. 7 thus rotated by 90 °.
  • the door guard 1 is arranged below the operating element 8 at the level of the handle rosette 21.
  • the abutting from below against the control element 8 pivot lever 13 is at an actuation the control element 8 in the direction of arrow B (ie pivoting about the control element pivot axis 5) in the direction of arrow A (ie pivoting about the pivot lever pivot axis 14) pivoted, both pivotal movements in the same pivot plane (yz plane) and run almost parallel to each other in the common pivoting movement ,
  • the pivot lever also strikes against the operating element 8 and in particular the handle in the area of the control element pivot axis 5 (alternatively, an arrangement of the door guard 1 on the side facing away from the control element pivot 5 side of the control element 8 or in the direction of a door hinge possible, this alternative of aesthetic Reasons is often considered disadvantageous).
  • the pivot lever 13 thus pivots in this arrangement, not to the door leaf, but parallel to the door leaf surface.
  • the hand engagement area on the control element 8 is thus not substantially limited by the pivot lever 13 in this manner, so that this embodiment is particularly safe.
  • Doors are basically available in a variety of different embodiments. This applies, for example, doors with door handles or panic bars, single or double-leaf doors, to the left or right hinged doors etc.
  • a door guard 1 which has a pivot lever bearing device 22, which makes it possible to arrange the pivot lever 13 in different positions on the door guard.
  • the bearing device 22 At the in Fig. 10 shown embodiment of the door guard 1, the bearing device 22 to three bearing points 23a, 23b and 23c on which the pivot lever 13 can be selectively mounted for connection to the housing 20 pivotally.
  • the door guard 1 is with its back on the surface of a door (not shown in FIG Fig. 10 ) assembled.
  • Fig. 10 is the pivot lever 13 at the left bearing point 23a (solid line) and is accordingly in the direction of arrow Aa to the door guard 1 pivoted out.
  • This arrangement is suitable, for example, especially for DIN left doors.
  • the pivot lever 13 pointing to the right on the door guard 1 at the bearing point 23c (dashed line, pointing to the right) are arranged so that it pivots in the direction of arrow Ac to the door guard 1 point.
  • This arrangement is intended especially for DIN-right doors.
  • Another alternative provides for the mounting of the pivot lever 13 at the middle bearing point 23b (also dashed line), so that the pivot lever 13 from the image plane in Fig. 10 protrudes.
  • the pivot lever 13 is pivotable in the direction of arrow Ab from the mounting surface.
  • This variant is particularly suitable for use with a panic bar.
  • the specific design of the bearing device 22 can be further varied. It is essential that they have different storage positions for the pivot lever 13 at the door guardian provides.
  • the securing device 31 On the other hand, if the securing device 31 is again activated or locked, it detects the position of the pivot lever 13 and triggers the alarm as soon as the pivot lever 31 is pulled out of its corresponding bearing.
  • a locking device can be controlled via the securing device 31, which locks the pivot lever 13 in activated storage device 31 in the corresponding storage.
  • Fig. 12 it is in a further alternative embodiment according to Fig. 12 also possible to store the pivot lever 13 in a rotary head 27, which is arranged via a pivot bearing 28 with the axis of rotation 29 on the housing 9.
  • the axis of rotation 29 extends vertically, so that the rotary head 27 is adjustable in a horizontal plane of rotation 30.
  • Essential for this embodiment is that the housing 9 no longer separate bearing points must be present and the positioning of the pivot lever relative to the housing is no longer determined solely by the bearing points.
  • the turret 27 has only one bearing point or a bearing 23, which is essentially freely rotatable by rotation of the rotary head 27 about the axis of rotation 29 in the xy plane in the direction of rotation 30 and thus indicated by the left position in one of the two dashed lines Positioning can be brought.
  • the essential advantage of this embodiment is thus that the pivot plane of the pivot lever 13 and the positioning of the pivot lever 13 can be adjusted individually by a rotation of the rotary head 27 relative to the housing 9.
  • the adjustment can basically be made continuously, with a detent adjustment, in this case in 20 ° steps, however, is preferred.
  • the present embodiment also has a securing device 31, wherein the securing device 31 is formed this time in the manner that it locks the rotary head in its rotational position in the activated state, so that, for example, an unauthorized person can not simply unscrew the door guard by unscrewing the pivoting lever 13 from the Swivel path of the corresponding control element can handle. If the securing device 31 is deactivated, on the other hand, the rotary head 27 can be rotated about the axis of rotation 29 in the plane of rotation 30, for example for adjustment purposes. Compared to the embodiment of the door guard 1 off Fig. 10 the pivot lever 13 is thus on the one hand fixed to the turret 27, but can be simultaneously rotated in different positions.
  • Another essential feature of the present embodiments of a door guard is further that also the angular position of the pivot lever 13 relative to the respective operating element 8 (in Fig. 2 Angle .beta.) Is adjustable, whereby this adjusting device, not specified, can be activated or released by the securing device 31 and can be deactivated or blocked.
  • this adjusting device not specified, can be activated or released by the securing device 31 and can be deactivated or blocked.
  • the position of the locking lever 13 both of the xy plane or in the horizontal plane and in the vertical direction or in the plane perpendicular to the xy plane pivot plane pivot lever 13 can be adjusted relative to the housing 9 to the position of the respective control element.
  • the position of the door guard 1 to the operating element must first be set only comparatively roughly.
  • FIG. 11 Finally, one concerns in relation to the arrangement Fig. 9 alternative relative arrangement between the trained as a door handle operating element 8 and the door guard 1 with its pivot lever 13. With respect to the structure and the operation is on the preceding figures, in particular Fig. 9 , Referenced. Important to the arrangement Fig. 11 is the lateral arrangement of the door guard 1 with respect to the operating element 8. The door guard is thus moved into the surface of the door leaf inside and lies on the side opposite the handle rosette 21 side. The pivoting lever 13 therefore contacts the operating element 8 also in the region of the operating element opposite the handle rosette 21. Presses an operator, the operating element in the direction of actuation B down (in Fig.
