Description

[0001] The invention relates to an anti-panic push bar for operating a door lock of an escape door or emergency exit door having the features of the preamble of claim 1.

[0002] A corresponding panic push bar is known from DE 10 2013 000 285 A1. This document describes an anti-panic push bar for an escape door or emergency exit door, comprising a base profile and an actuating profile that can be pushed in toward the base profile to open a door lock. The anti-panic push bar is mounted on top of a door.

[0003] The object of the present invention is to provide an anti-panic push bar for escape doors or emergency exit doors that is structurally simple and yet easy and reliable to operate. In particular, the anti-panic push bar should be able to be operated with relatively little effort. Preferably, the anti-panic push bar should be as comfortable to operate as possible, i.e., with as little disturbing noise as possible.

[0004] This object is achieved according to the invention by an anti-panic push bar having the features of claim 1.

[0005] According to the invention, an anti-panic push bar for actuating a door lock of an escape door or emergency exit door is proposed, comprising a base profile which can be mounted resting on a door leaf and an actuating profile which extends parallel to the longitudinal extent of the base profile and is movably mounted relative to the base profile, as well as a slide device with at least one longitudinally displaceable slide which is connected to an output nut for actuating a door lock, further comprising a transmission device for transmitting a movement of the actuating profile to the slide device in order to drive the output nut, wherein the base profile has a groove in the bottom region which extends along the base profile for displaceably supporting the at least one slide, and wherein the groove has a gap which is open towards the interior of the base profile and whose clear width is narrower than a transverse extent of the slide.It is essential that the slider has at least two sliding pieces on its upper side, which pass through the gap and guide the slider longitudinally in the gap.

[0006] Actuation of the anti-panic push rod is transmitted from the actuation profile to the slider of the slider device by means of the transmission device. The slider of the slider device is moved along the base profile. For this purpose, the slider is held on the base profile. The linear movement of the slider is then transmitted to the output nut by means of a nut gear and / or a crank rod. The output nut can be connected to a lock nut via a mandrel in order to open the lock. One advantage of the holder according to the invention in a groove that is open on one side, i.e. open towards the interior of the base profile, is that friction is reduced when the slider moves. Because the groove has a gap extending in the longitudinal direction, no friction can arise at this point. In addition, the sliding pieces further reduce friction and also ensure that the guide of the slider in the groove orThe gap can be opened without jamming or tilting. The reduced friction also reduces the annoying noises that would otherwise be associated with such friction. This advantageously allows for easier operation of the anti-panic push bar, as the force required for operation is reduced due to the reduced friction. Any annoying scraping noises resulting from friction can also be reduced accordingly.

[0007] In particular, a slider is understood to be a flat gear element running longitudinally along the base profile, used for power transmission and motion conversion. It consists of an elongated, straight body that is guided in a guide and moves in a translational manner. In particular, the slider has a rectangular cross-section.

[0008] In an advantageous embodiment, the at least two sliding pieces can be guided in the gap in a form-fitting and linearly displaceable manner. These sliding pieces can improve the support of the slider in the groove or in the gap of the groove. In particular, the sliding pieces can guide the slider or support the slider along the groove, thus further reducing contact between the slider and the groove or between the slider and the base profile.

[0009] In particular, it can be provided that the lateral play of the slider in the groove is greater than the lateral play of a sliding piece in the gap. This means that the slider has a greater distance on its side towards the guide groove than the sliding pieces that are guided in the gap of the groove. In practice, this means that the position of the slider within the groove is defined by the sliding pieces and the slider is guided at a distance from the side wall. This means that the sliding pieces form the only lateral contact points when guiding the slider. This allows the contact between the slider and the base profile or between the slider and the groove to be further reduced, which in turn results in reduced friction and improved guidance of the slider in the groove.

[0010] In particular, clearance refers to the clearance between the slide and the groove. This is the distance between the adjacent surfaces of the slide and the groove, which are in contact but not rigidly connected. Preferably, clearance refers to radial clearance or transverse clearance, i.e., the clearance in the transverse direction.

[0011] In particular, the slider can be provided with multiple attachment points to hold or fasten the sliding pieces, preferably with the sliding pieces being screwed or latched to the slider at the attachment points. This allows the sliding pieces to be attached at different longitudinal positions on the slider. Depending on the mechanical load, more or fewer sliding pieces can be used to support or guide the slider.

[0012] In particular, it can be provided that the attachment points are spaced apart from one another so that a sliding piece can be attached to different positions on the slide, in particular that the position of a sliding piece on the slide can be adjusted by changing the attachment point. For example, the length of the slide can be adapted to the length of the anti-panic push bar without requiring any redesign. The adjustment can be carried out simply by cutting the slide to length and repositioning the corresponding sliding pieces.

[0013] In an advantageous embodiment, it can be provided that a sliding piece has a stop on its upper side which interacts with an abutment to limit the adjustment travel of the slide. In this way, the actuation travel of the anti-panic push rod can be limited in a simple manner. This means that no additional components are required because the existing sliding pieces also serve as stops to limit the displacement travel of the slide. This travel can be limited in both directions. This means that in the opening direction of the door lock using a stop. The travel can also be limited in the opposite direction, i.e. in the closing direction of the connected door lock, in order to adjust the stroke of the actuation profile of the anti-panic push rod, for example.

[0014] In particular, it can be provided that the position of a sliding piece on the slider is adjustable and / or adjustable in such a way that the resulting adjustment path of the slider can be adjusted according to a rotation of the output nut by a rotation angle in the range between 20° and 45°, in particular that a rotation angle of 23°, or 25°, or 30°, or 35°, or 40°, or 45° can be set. This makes it possible to use the anti-panic push bar according to the invention for different types of door locks. Door locks typically have a lock nut that requires different rotation angles depending on the lock type. By simply varying the sliding piece on the slider using the prefabricated attachment points, the appropriate rotation angle for the corresponding door lock can be set without the need to redesign or redesign the anti-panic push bar.This allows the variety of variants in the production of the anti-panic push bar to be significantly reduced.

[0015] In one embodiment, a sliding piece can be made of a plastic, in particular POM (polyoxymethylene) or PTFE (polytetrafluoroethylene). Making the sliding pieces from a mechanically resistant yet lubricious plastic improves the bearing of the slider in the groove. In practice, the groove is made from a metal, such as aluminum or a steel alloy. The coefficient of friction between a hard plastic, such as POM or PTFE, and the corresponding metal of the groove is very low, so that the resulting friction that occurs when the anti-panic push rod is actuated is negligible. In addition, the sliding pieces made of plastic serve to reduce noise, since sliding friction between plastic and metal produces significantly less noise than friction between two metal surfaces.

[0016] In particular, it can be provided that the base profile is made of a metal, in particular a steel or an aluminum, and / or that the slider is made of a metal, in particular a steel and / or aluminum and / or a plastic.

[0017] In an advantageous embodiment, the slider can be designed as a three-part slider, comprising a central slider part and two outer slider parts that are connected to each other. The multi-part slider further simplifies the production of the anti-panic push bar. To create different lengths, it is not necessary to use a new slider each time; it is sufficient to change one of these three parts according to its length.

[0018] In an advantageous embodiment, the three parts of the slider can be separated from one another. By allowing the slider parts to be separated from one another or connected to one another, the installation of the long slider in the profile is simplified, as the short parts can be inserted into the groove and then easily connected, for example, by screwing or locking. This significantly simplifies handling compared to using a one-piece long slider.

[0019] Advantageously, the middle slide part can run outside the groove supporting the slide, in particular above the groove and / or above the gap. By having the middle slide part run outside of the groove rather than inside it, the resulting friction is further reduced. Since the middle part runs freely in the air, so to speak, there is no inhibiting friction on it. Also, no annoying scraping noises can arise at this point when the slide is operated. Only the two outer slide parts of the slide are guided in the groove. The two outer slide parts can be mounted on the sliding blocks with low friction and low noise.

[0020] In particular, it is provided that the two outer parts of the slide are guided in the same groove. The groove can be designed as a groove running in the longitudinal direction of the base profile, in particular as a continuous groove.

[0021] In one embodiment, the transverse extent of the central slider part can be smaller than the clear width of the gap and / or the groove. By making the transverse extent of the central slider part smaller than the width of the gap, a particularly low overall height can be achieved. This makes it possible to guide the central slider part outside the groove, but still within the gap, in such a way that the central slider part neither touches a wall of the groove nor a boundary wall of the gap, thus being guided in the air.

[0022] Advantageously, it can be provided that the middle slider part has a hole pattern in order to variably adjust the length of the slider, in particular has a regular hole pattern with a grid dimension in the range of 8 mm to 12 mm, preferably with a grid dimension of 10 mm. Using the grid dimension, a screw connection between the middle slider part and one of the outer slider parts can be adjusted in terms of length by adjusting the connection between the middle slider part and the outer slider part according to the required length in accordance with the grid dimension. This makes it possible to use one and the same slider for anti-panic push bars of different lengths and thus for different door widths. This further simplifies the manufacture of the anti-panic push bar according to the invention and reduces the variety of variants.To achieve a greater range of variability, it is also possible to shorten the slider by shortening the middle slider section accordingly. For example, the middle slider section can be shortened by the required amount, preferably by sawing it off, to adapt an anti-panic push bar to a particularly narrow door. The rest of the anti-panic push bar's construction can remain largely unchanged.

[0023] One application of the anti-panic push bar according to the invention is in escape and rescue route devices for building doors. Alternatively, the anti-panic push bar according to the invention can also be used in vehicles, such as ships or railway vehicles for emergency exit doors.

[0024] Further embodiments of the invention are shown in the figures and described below. In the figures: Fig. 1: an escape route device with an anti-panic push bar according to the invention; Fig. 2: a schematic representation of an anti-panic push bar according to the invention; Fig. 3: a schematic sectional representation of the anti-panic push bar from Fig. 2 ; Fig. 4 and 5: an enlarged detail in the area of ​​the operating lever of the anti-panic push rod; Fig. 6 and 7: a schematic representation of the multi-part slide.

[0025] The embodiments shown in the figures are exemplary and not intended to be limiting. Features with identical functions have been provided with the same reference symbols. It is obvious to the person skilled in the art that, within the scope of their technical skill and within the scope of the patent claims, they can combine the embodiments shown in the figures with one another without departing from the scope of the claims.

[0026] The Fig. 1 shows a schematic representation of an escape route device 1 with an anti-panic push bar 2 according to the invention. The anti-panic push bar 2 is mounted on a door leaf 12 of an escape door 11 or emergency exit door 11. The escape door 11 comprises a door leaf 12 pivotably mounted via hinges 131 and 132, which is fastened to a door frame 13. A mortise lock 14 is arranged in the door leaf 12 and interacts with the anti-panic push bar 2. The mortise lock 14 can be designed, for example, as a self-locking panic lock.

[0027] The anti-panic push bar 2 can be connected to an emergency button 15 and an alarm device 16 via an electrical connection 17, for example, an electrical data bus 17. The anti-panic push bar 2 can be electrically controlled via the electrical connection 17 or the data bus 17, for example, to switch an indicator or display on the anti-panic push bar 2 or to connect sensors. Optionally, the anti-panic push bar 2 can also be designed as a purely mechanical anti-panic push bar 2, i.e., without an electrical connection.

[0028] The escape door 11 is locked via an escape door opener 18. Normally, the escape door opener 18 is locked and prevents unauthorized opening of the escape door 11. The escape door opener 18 can be unlocked, for example, via an access control device to allow an authorized person to open the escape door 11. The person's authorization can be verified, for example, by a transponder, RFID, or key.

[0029] If an emergency occurs, pressing the emergency button 15 can trigger an alarm and unlock the door opener 17. The alarm device 16 then generates an alarm signal, and the escape door 11 is released for opening by everyone. The door lock 14 can then be unlocked by pressing the actuation profile 21 of the anti-panic push bar 2, and the escape door 11 can be opened by pivoting the door leaf 12.

[0030] It is also conceivable to connect a fire alarm device, for example a smoke detector or a fire alarm control panel, or to connect an escape route control or other components, such as an access control device, to the electronic bus 17 in order to electrically release and / or block the escape door 11.

[0031] The Fig. 2 shows a schematic sectional view of the anti-panic push bar 2 according to the invention. The anti-panic push bar 2 has a base profile 22, which can be mounted on a door leaf, for example, by screwing or gluing. The base profile 22 forms, so to speak, the back of the anti-panic push bar 2. On the front of the anti-panic push bar 2, an actuating handle 21 in the form of the actuating profile 21 is formed. To trigger the anti-panic push bar 2, pressure is exerted on the actuating profile 21, whereupon it is moved toward the base profile 22 along the illustrated direction of movement 7.

[0032] By means of a transmission device 26, this movement of the actuating handle 21 is transmitted to a slide device 23 arranged on the bottom of the base profile 22. The slide device 23 comprises at least one slide 4. The slide 4 is guided for translational displacement within a groove 24 in the bottom region of the base profile 22. This means that the slide 4 can be displaced along the longitudinal direction of the base profile 22. The transmission device 26 has two levers 261 and 262, which transmit the movement of the actuating handle 21 to the slide 4.

[0033] The slider 4 is connected to an output nut 25 via a nut gear 251. The translational movement of the slider 4 is converted into a rotary movement by the nut gear 251 to drive the output nut 25. The output nut 25 can be connected to a door lock via a pin (not shown) to open the door lock when the anti-panic push rod 2 is actuated.

[0034] Both the base profile 22 and the actuating handle 21 are U-shaped in cross-section. The open side walls of the two profiles face each other. The actuating profile 21 is guided within the base profile 22. Together, the base profile 22 and the actuating profile 21 form a space in which the mechanical and / or electrical components of the anti-panic push bar 2 are housed.

[0035] The slider 4 is guided in a groove 24 via sliding pieces 31, 32, 33, 34. The groove 24 is designed as a groove 24 open to the interior of the base profile 22, in that the groove 24 has a gap 243. The sliding pieces 31, 32, 33, 34 extend through the gap 243 to guide the slider 4 in a linearly displaceable manner.

[0036] The sliding pieces 31, 32, 33, 34 are connected to the top side of the slide 4, i.e., to the side of the slide 4 facing the installation space. The slide 4 has a plurality of attachment points 441, 442 on its top side for attaching the sliding pieces 31, 32, 33, 34. The number of sliding pieces and attachment points is variable, i.e., at least four sliding pieces 31, 32, 33, 34 are provided, but more than four sliding pieces can also be used. Each sliding piece 31, 32, 33, 34 corresponds to a attachment point 441, 442, etc.; in particular, more attachment points than sliding pieces are provided on the slide 4.

[0037] To attach a sliding piece 31, 32, 33, 34, this sliding piece is inserted into a fastening point 441, 442 and fastened there, for example by screwing.

[0038] To vary the length of the slider 4, the sliding pieces 31, 32, 33, 34 can be relocated accordingly and attached to new attachment points. This makes it possible, for example, to shorten the slider 4, preferably by sawing or cutting it off, to adapt the anti-panic push bar 2 to doors of different widths.

[0039] The sliding pieces 31, 32, 33, 34 are made of a low-friction, durable plastic, for example POM (polyoxymethylene). The sliding pieces 31, 32, 33, 34 guide the slide 4 in the groove 24 of the base profile so that it can be moved translationally. The play of the slide 4 in the groove is intended to be greater than the play of the sliding pieces 31, 32, 33, 34 in the gap of the groove. This prevents direct contact between the side wall of the slide 4 and the guide groove. This reduces friction. The slide 4 is constructed in several parts and has two outer parts 41 and 43 and a middle part 42. The middle part 42 is screwed to the outer parts 41, 43 by means of screws 422. The middle slider part 42 has a hole pattern 421 to adjust the length between the two outer slider parts 41, 43 of the slider 4.Using the screws 422, the screw connection can be varied according to the required length of the slider 4 using the hole pattern 421 in order to adjust the overall length of the slider 4.

[0040] In the Fig. 3 An enlarged cross-section is shown in the area of ​​the guide of the slide 4. The base profile 22 is U-shaped and has a guide groove 24 in the area of ​​its bottom for the translational guidance of the slide 4. The groove 24 comprises two side walls 241, 242, which each encompass the lateral longitudinal edges of the slide 4. The side walls 241, 242 have a T-shaped cross-section. The side walls 241, 242 can also be realized with an L-shaped cross-section. In the illustration of the Fig. 3 one can see the outer part 41 of the slider 4, which is connected to the middle slider part 42 via screws 422.

[0041] The groove 24 is open towards the interior of the base profile 22 and has a gap 243 running along the groove 24. The clear width 8 of the gap 243 is narrower than the transverse extent of the slide 4 or the outer slide parts 41 and 43. The middle slide part 42 has a transverse extent that is smaller than the transverse extent of the groove 24 and also smaller than the transverse extent of the gap 243. This means that the slide 4 is only guided at its two outer slide parts 41 and 43. The middle slide part 42 runs, so to speak, in the air and has no contact with the side walls 241 and 242 of the groove 24. As a result, no friction can arise in the area of ​​the middle slide part 42 and no disturbing noises can arise.

[0042] The sliding pieces 31, 32, 33, 34 are arranged in the area of ​​the two outer slide parts 41 and 43. In the Fig. 3 one can see the sliding piece 32 as an example. The sliding pieces pass through the gap 243 and are dimensioned such that their transverse dimension engages positively in the gap 243. This means that the sliding pieces 31, 32, 33, 34 are received in a positive-fitting manner and can be moved linearly within the gap 243. The sliding pieces 31, 32, 33, 34 have a stop 35 or a web 35 on their upper side. The translational movement of the slide 4 can be limited by means of this stop. This allows the stroke of the actuating profile 21 to be adjusted. The resulting rotary movement of the output nut 25 can also be adjusted accordingly. Depending on the position at which the corresponding sliding piece is attached to the slide 4, a larger or smaller angle of rotation of the output nut 25 can be realized.

[0043] In Fig. 4 is a detailed enlargement of the anti-panic push rod 2 in the area of ​​the first lever 261 of the transmission device 26. The lever 261 cooperates with the first outer slide part 41 to move the slide 4 translationally along the base profile 22. On the Fig. 4 The two sliding pieces 31 and 32 are mounted on the outer slide part 41 shown, ie they are received in their corresponding fastening points. An unoccupied fastening point 441 is in Fig. 4 can also be seen.

[0044] In the Fig. 5 An enlarged detail of the second lever 262 of the transmission device 26 is shown. The transmission lever 262 cooperates with the second outer slide part 43 to move the slide 4 translationally along the base profile 22 when pressure is applied to the actuating profile 21. Fig. 5 The sliding piece 34 with its stop 36 or its web 36 is clearly visible. In the Fig. 5 In the position shown, the sliding piece 34 has come into contact with the abutment 263 and thus limits the movement of the slide 4 in the direction shown in Fig. 5 Sliding direction shown to the left. Depending on the position of the sliding piece 34 on the slide 4 or the outer slide part 43, the translational path traveled by the slide 4 can be adjusted. Since the slide 4 is connected to the output nut 25 via a nut gear, this results in a greater or lesser rotary movement of the output nut. In this way, it is possible to connect the anti-panic push rod to different rotation angles of a door lock. For example, the translational path of the slide can be adjusted by moving the sliding pieces so that rotation angles in the range of 20° to 45° can be covered. Discrete rotation angles can be set, for example 20°, 23°, 25°, 30°, 35°, 40° and 45°.These values ​​are to be understood as examples only and can of course be varied according to the circumstances by prefabricating the fastening points 441, 442 of the slider according to the positions.

[0045] In the Figuren 6 und 7 The structure of the multi-part slide 4 is shown enlarged. In the Fig. 6 The two outer slide parts 41 and 43 are shown, along with the middle slide part 42 connecting these two outer slide parts 41 and 43. The middle slide part 42 has a hole pattern 421 for screwing the middle slide part 42 to the two outer slide parts 41 and 43 using screws 422. By selecting different fastening holes, the distance between the two outer slide parts 41 and 43 can be varied. This allows the overall length of the slide to be adjusted without having to machine components, for example, by cutting them to length.

[0046] In the Fig. 7An exploded view of the assembly of the middle slider part 42 to the two outer slider parts 41 and 43 is shown. The two outer slider parts 41 and 43 are inserted into the groove 24 of the base profile 22 and moved to their outer positions. The middle slider part 42 is then inserted and screwed to the outer slider part 41 and the outer slider part 43 using screws 422. This type of assembly enables simplified assembly of the anti-panic push rod 2, since the slider 4 does not have to be inserted as a whole into the groove 24, which is formed as a continuous groove on the base profile 22.

[0047] One advantage is that the central slider part 42 has no contact with the groove 24, thus preventing friction and disturbing noises at this point. This reduces the actuation forces required to activate the anti-panic push rod. Another advantage is that jamming is also prevented at this point. List of reference symbols
