Door

The invention relates to a goal with a between a closed position and an movable opening position and extending a plurality of parallel with respect. Tilting axes against each other tiltable Torblattelementen having door leaf, integrated in the door panel door with an approximately perpendicular to the tilt axes extending pivot axis with respect. in the direction of the tilt axes adjacent Torblattelementen pivotable, in its closed position in a recess of the door leaf recorded, and preferably arranged in the closed position approximately at the door leaf Door leaf and a deformation of the door leaf counteracting stabilizing assembly and a safety device for doors of this type.

Goals with a plurality of respect. Mutually parallel pivot axes against each other tiltable Torblattelementen having door leaves are in Form of garage doors and in the form of industrial doors to close off roads used in garages and industrial halls. In both cases, the door leaf is usually over in the closed position approximately in a vertical plane and in the open position Head disposed approximately in a horizontal plane. To guide the door leaf between the closed position and the open position are typically guide rails with an approximately rectilinear and approximately parallel to the lateral Torblattrand in the closed position extending vertical section, a further approximately rectilinear and approximately parallel for lateral Torblattrand extending in the open position and the horizontal portion one connecting the two straight portions of each arcuate portion provided. In order to enable the door leaf along the arcuate portion the door leaves of the door leaf at right angles to the guide rails extending tilt axes against each other tiltable interconnected.

If a person leaving a sealed with such a target area wants, needs in industrial doors have a width of 5 m or more having the door leaf as A whole are moved from the closed position to the open position. That does not mean only a considerable increase in the load on the mechanical elements of the door leaf, but is also associated with a significant amount of time. To achieve this Problems it has been proposed a door with a about an approximately perpendicular to the Tilting axes and in the closed position of the door leaf runs approximately in the direction of gravity Pivot axis with respect. The adjacent Torblattelementen pivotable door leaf in the Door leaf integrate. Such "wicket" allows the exit with the Door leaf closed room without opening the door panel as a whole. Much more has only to the built in the door leaf the door leaf by pivoting about the pivot axis be opened. In order to enable an opening movement of the door leaf with the therein integrated door leaf is also the door leaf such constructions usually a plurality of respect. collinear with the tilting axes extending axes to today tiltable door leaf elements.

In such constructions must be ensured that the door leaf with the integrated therein door leaf in the open position in which the door leaf about in a horizontal plane is disposed not in a plane perpendicular to the door leaf plane direction sags. Furthermore, the closed position must be ensured in the course of that both sides of the door leaf arranged door leaves is not in the direction of the tilt axes apart. This problem is particularly evident in industrial doors forth, in which the door leaf drive means of the lateral edges of the two Door leaf coupled to the bottom in the closed position the door leaves traction means are used. The attack of the traction means at the lateral edges of the door leaf can in these constructions the tendency for expansion of both sides of the door leaf elements promote arranged door leaves in the direction of the tilt axes.

In conventional doors of the aforementioned type, the required Stability by means of stabilization arrangements in the form of the door leaf receiving Recess completely encircling and attached to neighboring Torblattelementen Door frame can be achieved. In this case, which is the lower edge of the recess forming edge members usually forming on a the bottom segment the lower Torblattelementes attached. In this way, using the in this case over the entire doorwidth extending lower Torblatteleme n-th and the lower edge members reached a sufficient stability of the overall construction. However, the lower Torblattelement forms together with the lower fixed thereon Edge members a trip hazard. For this reason, the conventional in a Door leaf captured passdoors not recognized as an escape route.

To solve this problem when using conventional wicket doors is in the WO 01/055543 a further development of the known goals proposed in which the in the door leaf taken the door leaf in the closed state of the door while avoiding the formation of a trip edge up towards the bottom extends. The required stability this overall construction in the open position and during the closing movement is in the known from the cited document goal by stabilizing arrangement in The form of a locking device can be achieved, which in the door leaf open position with respect to a movement of the door leaf. counteracts the adjacent Torblattelementen. For this purpose, the method known from the cited document Goal least one parallel to the Tilting shafts horizontally movable sliding bolt in the bottom region of Zargenanordnung or of the door leaf on which, in the locking position in an opening engages in the door frame or the door leaf. Further comprising the in the form of locking device formed stabilizer assembly of the known stores a parallel to a Pivot axis extending axis pivotable latch element when moving the pushing pin is pressed into the opening of the sliding bolt to the side, wherein this Locking element with a racing-like end behind the edge of an abutment summarizes the door or gate segment and clicks securely. This is a movement of both sides of the door leaf arranged door leaves in the horizontal direction in the Main plane of the door can be prevented, so the above-described mounting a gap between door and frame or adjacent Torblattelementen during the opening or closing movement of the door leaf to stop.

When using described in WO 01/055543 gates it has, however, shown that, and despite the measures described above, with a door leaf-opening -Schließbewegung Because of the inevitable to ensure reliable operation Game of the motion of sliding bolts and locking element to a considerable Gapping between the door and the adjacent Torblattelementen comes and Moreover, the door leaf in the open position overall in a plane perpendicular to the door leaf extending direction sags in an unacceptable way. in view of these problems has been a development of the described in WO 01/055543 proposed goals, wherein the forming the stabilization assembly arresting at least one approximately perpendicularly to the tilt axes extending in a plane having preferably approximately parallel to the pivot axis movable locking element. With this development, the gap formation described can be prevented. though is the so executed stabilization assembly with a considerable constructive associated expenses.

In view of the above-described problems in the prior art, the Invention, the object of providing a structurally simple executable Goal of the above provide the type mentioned, on the one hand, the requirements for an escape route met, and on the other hand has a sufficient overall stability.

This object is achieved by a further development of the known goals dissolved, which is essentially characterized in that the stabilizing arrangement in the closed position of the door leaf on the floor of the closed with the door leaf Opening resting, the lower edge of the door leaf receiving recess forming and preferably adjacent to the recess in the direction of the tilt axes Gate elements fixed threshold element, the height of which in the direction Pivot axis at least in the region of its preferably approximately parallel to the tilt axes extending edges of less than 20 mm, preferably less than 10 mm, particularly preferably less than 8 mm, especially 5 mm or less.

This invention is based on the recognition that the conventional at the Gates of the type described initially observed deformations of the door leaf by Bending in a direction perpendicular to the door leaf towards the one hand and adjacent by spreading of the door leaf recess accommodating door leaves the other, by structurally separate from each other elements of the stabilization assembly can be prevented, whereby only the sagging of the door leaf counteracting in a direction perpendicular to the door leaf direction element the receiving of the stabilizing arrangement in the region of the lower edge the door leaf Recess has to be arranged, while the observed spreading of the Recess adjacent door leaves by an above the recess arranged stabilizing element and in the simplest case even by an upper Torblattelement can be prevented. Here, the sag in a plane perpendicular to Door leaf extending towards effectively already with a threshold element exported stabilizing element can be achieved, which only in the deflection direction a considerable extent and having appropriate stability, while in having the perpendicular thereto toward the pivot axis, only a small amount must because a stabilization in this direction by the other, possibly above the Recess arranged stabilizing element occurs. Therefore, the threshold element with a particularly low height of less than 20 mm, preferably less than 10 mm, more preferably less than 8 mm, especially 5 mm or less in the Range of parallel to the tilt axes extending edges are performed. by virtue of This low level of the threshold element there are no concerns when using integrated into the blade of a wicket gate according to the invention as an escape door.

To obtain a sufficient stabilization effect in a direction perpendicular to the door leaf extending direction, the width of the threshold element in this direction expediently larger than the door leaf in this direction. She is expediently more than 150%, preferably more than 200%, particularly preferably more than 250 % Of the door leaf, in particular 300% of the door leaf or more, with the Threshold element preferably extending over the entire door leaf so as to on the one hand to achieve better stabilization and on the other hand an excessive cantilevering over To prevent the door leaf. In view of the Erhait a balanced compromise between stability on the one hand and cost and space requirements on the other hand, is the width of the threshold element expediently less than 350%, preferably 300% or less of the door leaf.

The width of the threshold element can for obtaining the desired stabilizing effect regardless of the door leaf has a value of 60 mm or more, expediently 80 mm or more, preferably 100 mm or more, particularly preferably 120 mm or more, particularly 140 mm or more.

To obtain one of the deflection in a direction parallel to the pivot axes extending Towards counteracting stabilizing effect and the simultaneous deployment a receptacle for a provided at the bottom of the door leaf seal element it has proven to be particularly advantageous if the preferably at least in sections of a material having a tensile strength greater than 120 N / mm², especially more than 370 N / mm², More preferably more than 540 N / mm² formed Threshold element in the region of at least one of its preferably approximately parallel to the Tilting axes extending edges to form a line extending in the direction of the tilt axes Receptacle for a sealing member on its the closing position of the door leaf in lower boundary surface is bent back on itself. To obtain a reasonable compromise between stability on the one hand and cost and processability On the other hand, it has proved to be advantageous if the threshold element a tensile strength of less than 1000 N / mm², Preferably less than 900 N / mm², In particular less than 750 N / mm² , wherein the tensile strength range 540-750 N / mm² has proven particularly favorable.

Additionally or alternatively, the threshold element may be an approximately parallel the tilting axes extending and in the closed position, downwardly open channel between having its lateral edges, for receiving a fastening section of the the sealing element can be used.

To avoid a trip hazard in the area this preferably approximately centrally between the lateral edges of the channel threshold element formed it has proven advantageous if the lateral boundary walls of the channel ramp-shaped fall towards the lateral edges of the threshold element, being in the closed position, preferably an angle of less than 60% with a horizontal plane lock in.

In all embodiments of the invention, it has in respect to the desired proved avoid tripping hazard as particularly advantageous if the total height the threshold element less than 22 mm, preferably less than 12 mm, more preferably less than 10 mm, in particular 7 mm or less, and if even at threshold elements with a higher total amount the formation of a Trip hazard by providing corresponding ramped wall elements can still be prevented.

Emerging elements according to the invention are preferably made of a material goals high tensile strength, such as steel, with a material thickness of 3 mm or less, preferably 2 mm or less prepared by the if necessary additional cranks can be stabilized or bending. In the present invention, however, is also to the Use of threshold elements of other materials, such as composites, for example, glass fiber reinforced plastic, or Kevlar, optionally in combination with steel, intended. With Material thickness of 3 mm or less and 2 mm or less can threshold elements with one serving to receive a sealing element, while avoiding channel be an excessive amount of the threshold element produced. If a Sealing member is not required and / or the sealing element below the attached threshold element without the use of a channel formed in the threshold element can be, is the use of threshold elements of a material with a material thickness of 7 mm or less, more preferably 6 mm or less, particularly preferably 5 mm or less conceivable. In this case, a material thickness of about 5 mm particularly expedient.

As already mentioned above, it has in view of obtaining a tight opening statements proved in the closed position of the door leaf to be expedient, if in the region of the lower boundary surface in the closed position of the threshold element a is approximately parallel to the tilt axes, preferably over the entire Doorwidth extending sealing element is mounted. In this case, the sealing element a preferably at least partially in the channel of the threshold element received fitting portion and at least one, preferably two or more, starting them in opposite directions obliquely downward have sloping sealing flap. A particularly good sealing action is obtained when at least one said mounting portion remote from the edge of at least one sealing flap is at least partially bent in the closed position to the top, because this Edge then by contact of the sealing flap at the bottom of the opening to be closed is urged against the lower boundary surface of the threshold element, so as to provide provide reliable sealing between the floor and the threshold element. In connection with the use of a further aspect of the invention forming Safety device, it has proven to be especially effective when the Sealing member preferably in the region of its mounting portion of a possibly open at the top and extending approximately in the direction of the tilt axes cable channel is penetrated. In this cable channel, a cable connecting the individual elements of a safety device be inserted for an inventive target.

Upon reaching the closed position, the sealing flap of the sealing element are respect. the mounting portion bent upward. Excessive wear of the The sealing element can be prevented by this turn if at least one Sealing lips on at least one intended bending point low material thickness with the fixing portion connected is.

The desired stabilization effect is particularly reliable achieved if the threshold element in the bottom in the closed position the edges of the recess in Direction of the tilt axes adjacent door leaves is secured. Considering the fact that the individual door leaves independent in the large-scale production be prepared from their their later usage uniformly, it has proven to be proved particularly advantageous if the fixing of the threshold element is a one part, at the lower edge of one of the door leaves and on the other hand to an upper boundary surface the threshold element attached fastening element is used. In this case, an integral attachment, such as gluing, are also employed come as a positive fastening such as bolting. Preferably is a combination of two types of attachment, optionally with additional stabilization by a non-positive fastening, for use.

It has already been explained that the width of the threshold elements according to the invention Goals in a direction perpendicular to the door leaf direction preferably greater than the door leaf. In some embodiments of the invention it must be prevented that people in the door leaf-closed position on the can stand threshold element and after during an opening movement to the door leaf be drawn up. To this end, it has proved to be particularly favorable when the fastening element comprises a proceeding from the door leaf outer side in the closed position obliquely downward toward an outside edge of the threshold element sloping upper boundary surface section and / or one of the Torblattinnenseite in the closed position obliquely downwards towards an inside edge having the threshold element sloping upper boundary surface section, at least one of the upper boundary surface sections in the closed position a Angle of 10 ° or more, preferably 15 ° or more, particularly preferably 20 ° or more forms with a horizontal plane. In this embodiment, the invention fasteners it is achieved that a limit to an upper surface portion occurring foot slipped from this boundary surface portion and no safe Stand it finds, so that there is no risk to the extent that one of the fastener or the threshold element person standing at a door leaf opening movement is with drawn upward.

Conventional cross-sectional shapes of Torblattelementen, which in addition to the necessary stability sufficient finger protection is also achievable, are described for example in EP 304 642 and EP 370 376. The disclosure of these documents with regard to the cross-sectional shapes of conventional door leaves or Panels in a direction perpendicular to the tilt axes extending cutting plane is hereby incorporated by express reference into this description. In these conventional Torblattelementen is in the region of the lower edge of the door leaves a recess is provided into which a projection in the region of the upper edge of a can engage the adjacent panel. With regard to the purposes of this invention objective of stabilizing effect, it has proven to be advantageous when the fastener one extending in a parallel to the tilt axes open below having depression recorded in the bottom of the door leaves projection. Further stabilization can be achieved if the fastening element between a a voltage applied to an inner surface of the door leaf wall element and the projection formed receptacle for receiving one at the bottom of Torblattelementes having arranged projection.

As already explained, the door leaf inventive goals expediently also a plurality collinear with the tilting axes extending of respect. Axes against each other tiltable door leaf elements.

Manufacturing technology, it has proved to be particularly useful if the Door leaf elements in a direction perpendicular to the tilt axes extending cutting plane about the have the same shape as the door leaves. In this case, normally between the lower edge of the door leaf and the threshold element of the height of the fastening element appropriate distance released. A tight seal in the region the lower edge of the door leaf is achievable if at the door leaf in the closed position lower door panel element, a transition element is mounted, which in the Door leaf-closing position between the threshold element and the lower door panel element is arranged. In this case, one in the door leaf-closing position, the transition member the fixed to the adjacent Torblattelementen threshold element fitting have seal assembly. In order to provide a reliable seal comprises such a sealing arrangement expediently into the door panel closed position Fitted on a front boundary surface of the threshold element sealing element and / or in the door leaf-closing position to an upper boundary surface of the Threshold element fitting sealing element.

To obtain an attractive outer appearance of the inventive Gate, and in view of the above-described risk of the occurrence of the threshold element, it has proven to be particularly useful if the transition element at least in the region of the door leaf outer side in a direction perpendicular to the tilt axes sectional plane running approximately the same shape as the fixing member, ie a sloping toward the outer edge of the threshold element upper having boundary surface section, and in addition also a the toward provided inside edge of the threshold element sloping upper boundary surface section can be. Additionally or alternatively, also the color designs coordinated transition element and fastener together, especially identical, more preferably according to the color design of conventional Sealing arrangements, be executed in black. Also included within the transition member expediently a in a recess in the bottom of the lower door panel element engaging projection.

As already explained above in detail, by the threshold element an inventive door to the bending of the door leaf in a direction perpendicular to Door leaf extending direction counteracted. The bending of the door panel in a parallel to the pivot axis extending direction, with the aid of an above disposed of the door panel receiving recess and spanning the recess Stabilizing element can be counteracted. This stabilizing element may in a particularly simple embodiment of the invention by above of the door leaf receiving recess arranged continuous Torblattelement be realized. The stabilizing element comprises, for obtaining the desired Stabilizing effect expediently a door leaf in the closed position approximately in a vertical plane disposed on boundary surface, which, in a particularly preferred embodiment of the invention of a substantially flat Layer is formed of a material with high tensile strength.

In cases where the top in the closed position Torblattelement a the having top of the door leaf receiving recess forming segment, so that provided by the supreme Torblattelement insufficient stabilizing effect may be, it has proved to be advantageous if an additional stabilizing element received in a recess above the arranged Torblattelement and / or on an inner boundary surface of a recess above the arranged Torblattelementes secured. In this case, this additional stabilization element in the form of an open in the direction of a channel with a Torblattelement in the closed position approximately in a vertical plane extending channel floor and for fixing this additional stabilizing element at the inner limit surface Torblattelementes of serving based on the channel walls outwardly bent have flanges.

In an electrical drive means between the closed position and Open position movable gates must be ensured that upon impact of at the closing movement leading edge of the door leaf on an object or a Person in the course of the closing movement an automatic shutdown of the electrical Drive is. Conventional doors for this purpose have a power limit of Drive on, with it is achieved that when exceeding a predetermined driving force an automatic shutdown occurs. However, this disconnection takes place only after a by the inertia of the door leaf-related delay. During the delay time distance Wegstecke is conventional gates through the lower Edge of the door leaf seal assembly located incorporated. In the present invention However gates may particularly thin seal assemblies for use come, wherein a lower edge of the door leaf with a non-through a sealing element protected section of the threshold element in the course of the closing movement can impinge an object or a person. In this case, despite the known Power limit still considerable property damage or injury People occur.

With a goal with a between a closed position and an open position movable and preferably a plurality of regard. parallel to each other Tilting axes against each other tiltable Torblattelementen having door can this risk be excluded according to a further aspect of the invention characterized be that one for detecting objects or persons in the area of ​​a trajectory designed of a leading edge during a closing movement of the door leaf non-contact safety device is used.

With such a safety device is of the during the closing movement leading edge of the door leaf traversed path already monitored without contact, before this leading edge reaches the respective track section. Then can be carried out switching off the drive before the door leaf of a in the range Trajectory arranged object or there existing person applies. A Such securing means may not only for doors with integrated inventive Wicket, but also in conventional gates are used without wicket door. Particularly useful to the use of such safety devices is however at Gates invention with integrated wicket door and one on the lower boundary surface the threshold element arranged seal assembly of small thickness.

The safety device according to the invention Goals expediently has at least a transmitter arrangement for delivering wireless signals transmitted in a approximately parallel to the tilting axes extending direction and at least one receiver assembly for receiving on the output from the transmitter array signals, wherein the transmitter arrangement and the receiver arrangement expediently in the range of opposing lateral edges of the door panel mounted, preferably on Door blade attached. The signals from the transmitter arrangement are expediently parallel to the voriaufenden in Schüeßbewegung edge of the door leaf in the direction of delivered closing movement against this edge, so objects and people captured can be before the edge of the door leaf during the closing movement it incident.

For use in connection with gates according to the invention, in which the width the threshold element in a direction perpendicular to the door leaf in the closed position Direction is larger than the door leaf, it has to give a highly reliable Locking effect proved to be expedient if the transmitter arrangement for Outputting signals along two or more in a direction perpendicular to the door leaf Direction offset from each other and arranged preferably approximately parallel is operable to tilt axes extending pathways. With such transmitter devices , a moving element with the threshold signal grid in the of the Threshold element traversed zones are created, the interruption only a grid element formed by the individual signal paths in the course of the door leaf be utilized for generating a switch-off signal for the door drive can.

With regard to the production of suitable signal grid, it has, for cost reasons proven particularly advantageous if at least two signal paths of a common transmitter element are fed. This may conveniently by using allows deflection in the region of the mutually opposite edges of the door leaf will. In view of obtaining a particularly reliable locking action it has proven to be expedient when the transmitter arrangement at least two comprises transmitter elements, each of which is for feeding at least one signal path is designed. The two just described embodiments, it has dropped out Cost reasons proved to be advantageous when at least two signal paths a common is receiver element of the receiver assembly associated.

As part of the large-scale manufacture of gates of the inventive type can manufactured transmitter devices and receiver assemblies only with limited accuracy and secured. Furthermore, it must in the course of the door leaf, especially in door leaves with integrated wicket to be reckoned with minor Torblattverformungen. For these boundary conditions, a reliable operation of the safety device a goal of the invention are ensured when the transmitter assembly for outputting signals in a signal cone with an opening angle of more than 2 °, preferably 5 ° or more configured with an excessive transmission power at while ensuring a reliable signal reception is avoidable if the Opening angle of the cone signal 20 ° or less, in particular 10 ° or less, particularly is preferably 8 ° or less.

As already explained, the door leaf runs through during the closing movement and thus also the leading edge in the closing movement of the door leaf an arcuate Section a predetermined path between a vertical guide rail section and a horizontal guide rail section. In particular for garage doors with a total height of 2.50 m must also in this arcuate Portion of the predetermined path, the impingement of the leading end during the closing movement Torblattrandes be reliably prevented to objects or people. In this connection it has proved to be particularly advantageous if at least an element of the transmitter arrangement, such as an example in the form of a light source actualized transmitter element or actualized for example in the form of a mirror Deflection element and / or at least one element of the receiver array, such as a been realized in the form of a photodiode receiver element or in the form of a mirror actualized deflection element via a coupling arrangement to a substantially parallel to the Tilting axes extending pivot axis which is fixed to the door leaf. On this way it can be achieved that the pivotally arranged transmitter element and / or receiver element when passing through the arcuate portion of the predetermined Web related. The leading edge of the door leaf is pivoted and thus any At the time of shooting action approximately in a vertical plane with this leading Edge is arranged. In this context, it has further to be particularly useful been found when, for limiting the pivotal movement of the element of the transmitter array and / or the element of the receiver assembly, a stop assembly is provided such that the pivotally mounted member during the closing movement at least along a portion of the path of movement during the closing movement leading edge of the door panel below this edge as a the leading Vertical plane containing the edge is arranged.

For safety reasons, it has proved advantageous if the coupling assembly and thus also an affixed member of the receiver assembly and / or the transmitter arrangement secured to an inner boundary surface of the door leaf is to allow access to the coupling assembly and attached elements is prevented when the door leaf is closed from the outside. In this preferred embodiment, the invention, the desired arrangement of on the coupling assembly fixed element of the receiver assembly and / or the transmitter assembly in a reaches vertical plane with the leading edge in the closing movement of the door leaf , when the coupling assembly in the region of one in the closing movement leading edge with respect. a parallel to the tilt axes extending pivot axis pivotably on the door leaf, in particular an inner boundary surface of the door leaf having fixed coupling lever which the at least one pivot position engages during the closing movement of the door leaf leading edge. For this purpose, the Coupling lever two or more runs in each case in a direction perpendicular to the tilt axes Plane an angle of less than 180 ° inclusive with each other, preferably in the have substantially rectilinear lever segments.

As already explained above, the pivotal movement of the coupling assembly be limited by an appropriate stop arrangement so that the coupling assembly not too far from the leading during the closing movement of the door leaf Edge pivots away and ensures that the attached to the coupling assembly Element of the transmitter arrangement and / or receiver assembly in the area of ​​the arcuate Portion of the predetermined path approximately in a vertical plane with the at the closing movement of leading edge of the door leaf is arranged. This limitation the pivoting movement of the coupling arrangement, however, leads to the fact that the coupling assembly on impact on the bottom of the door leaf to be closed space or impinging on a subject lying on the ground or persons part only yet can yield to a limited extent. This can lead to damage of the coupling assembly, the objects lying on the ground and / or to a personal injury to lead. This risk can be reduced if at least two lever segments the coupling lever respect. a parallel to the tilt axes extending pivot axis are pivotally connected with each other, wherein preferably a pivoting the lever segments is limited by a further fence assembly. in the History pivoting lever segments are going to these segments to move. In this way, the coupling assembly in the final stages of opposite closing movement of the door leaf in a direction of movement shortening direction, so that the area bounded by the fence assembly pivoting for ensuring trouble-free operation of the invention with a Safety device equipped gate sufficient and also damage of Objects on the bottom of the opening to be closed and / or injury of People can be reliably prevented.

Damage of transmitter elements, deflecting elements and receiver elements the safety device according to the invention Goals can particularly easily avoided when your pivoted on the door leaf mounted coupling lever for receiving a at least one transmitter element, at least one receiver element and / or at least one deflecting element being blank housing. Because of this Housing, the said elements without affecting their functioning be protected from damage. To obtain the desired function of the monitoring one to be run through by the threshold element space, it has to be particularly proved favorable if the housing in the pivot on which the door leaf attached Lever segment mounted lever segment is arranged. To ensure the Function in use of gratings signal with two or more longitudinally parallel to each other extending pathways propagating signals has to be expedient proved, when the housing has two or more windows for respectively at least one longitudinally having one of the signal paths propagated signal.

The safety device according to the invention can be carried out particularly compact Goals , when an end portion remote from the pivot axis of the pivotally connected to the lever segment attached to the door leaf lever segment concerning. the fastened to the door leaf segment lever is arranged offset in the direction of the tilt axis, because in this arrangement, the lever segment arranged offset in the door leaf-closing position can be placed next to the door leaf.

As already explained above, is a fastened to the coupling assembly Element of the safety device, conveniently at reaching the closed position the door leaf automatically in the interior of the closed space with the door leaf pivoted, said coupling arrangement expediently to dodge in a the closing movement of opposite direction in encountering an obstacle in is adapted to the final phase of the closing movement.

A safety device according to the invention for an inventive goal is essentially by a transmitter element and / or receiver element and a pivotable to Coupling this element designed to a gate panel coupling arrangement in which the transmitter element is a light source and the receiver element may include a photodiode and the coupling assembly comprises a coupling lever having two or more possibly mutually articulated lever segments can.
