Anti-panic push rod with guide

Description

[0001] The invention relates to an anti-panic push bar for actuating a door lock of an escape door or emergency exit door with 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 which can be pressed inwards towards the base profile to open a door lock. The anti-panic push bar is mounted on top of a door. Furthermore, EP 2 439 362 A2 discloses a panic push bar according to the preamble of claim 1.

[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 easy and reliable to operate. In particular, the anti-panic push bar should require relatively little effort to operate. Preferably, the anti-panic push bar should be as comfortable as possible, i.e., operable with as little disturbing noise as possible.

[0004] This problem is solved according to the invention by an anti-panic push bar with 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 that can be mounted resting on a door leaf and an actuating profile extending parallel to the longitudinal extent of the base profile, which is movably mounted relative to the base profile, as well as a sliding device with at least one longitudinally displaceable slide, which is connected to a drive nut for actuating a door lock, further comprising a transmission device for transmitting a movement of the actuating profile to the sliding device in order to drive the drive nut, wherein the base profile has a groove extending along the base profile in the bottom area for displaceably mounting the at least one slide, and wherein the groove has a gap open towards the interior of the base profile, the clear width of which is narrower than a transverse extent of the slide.The essential point is that the slider has at least two sliding pieces on its upper side that extend through the gap and allow the slider to be moved longitudinally within the gap.

[0006] Actuation of the anti-panic push rod is transmitted from the actuating profile to the slide of the slide mechanism via the transmission device. The slide of the slide mechanism is thereby moved along the base profile. For this purpose, the slide is held in place on the base profile. The linear movement of the slide is then transmitted to the output nut via a nut drive and / or a crank rod. The output nut can be connected to a lock nut via a mandrel to open the lock. An advantage of the mounting according to the invention in a groove open on one side, i.e., open towards the interior of the base profile, is that friction during the movement of the slide is reduced. Because the groove has a longitudinally extending gap, no friction can occur at this point. In addition, the sliding pieces further reduce friction and also ensure that the guide of the slide in the groove is secure.The opening of the gap can be achieved without jamming or tilting. The reduced friction also minimizes any disruptive noises that would otherwise accompany such friction. This advantageously simplifies operation of the anti-panic push bar, as the force required for operation is reduced due to the lower friction. Any disruptive scraping noises resulting from friction are also correspondingly reduced.

[0007] In particular, a slide is understood to be a flat transmission element extending 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 moved translationally. Specifically, the slide has a rectangular cross-section.

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

[0009] In particular, it can be designed so that the lateral play of the slide in the groove is greater than the lateral play of a sliding piece in the gap. This means that the slide has a greater distance on its side from the guide groove than the sliding pieces guided in the gap of the groove. In practice, this means that the sliding pieces define the position of the slide within the groove and guide the slide with a gap to the side wall. That is, the sliding pieces form the only lateral contact points for guiding the slide. This further reduces the contact between the slide and the base profile, and between the slide and the groove, which in turn results in reduced friction and improved guidance of the slide in the groove.

[0010] In particular, "play" 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, "play" refers to radial play or transverse play, i.e., play in the transverse direction.

[0011] In particular, the slide may be provided with multiple attachment points for holding or securing the sliding pieces, preferably with the sliding pieces being screwed or snapped to the slide at these attachment points. This allows the sliding pieces to be attached at different longitudinal positions on the slide. Depending on the mechanical load, more or fewer sliding pieces can be used to support or guide the slide.

[0012] In particular, the mounting points can be spaced apart so that a sliding piece can be attached to different positions on the slider, and especially so that the position of a sliding piece on the slider can be adjusted by changing the mounting point. For example, the length of the slider can be adapted to the length of the anti-panic push bar without requiring any modifications. The adjustment can be made simply by shortening the slider and repositioning the corresponding sliding pieces.

[0013] In an advantageous embodiment, a sliding piece can be provided with a stop on its upper side, which interacts with an abutment to limit the slider's travel. This allows for simple limitation of the anti-panic push bar's operating travel. This means that no additional components are necessary, as the existing sliding pieces simultaneously serve as stops to limit the slider's movement. This travel can be limited in both directions: firstly, in the opening direction of the door lock by means of a stop; and secondly, in the opposite direction, i.e., in the closing direction of the connected door lock, to, for example, adjust the stroke of the anti-panic push bar's operating profile.

[0014] In particular, the position of a sliding piece on the slider can be adjusted such that the resulting adjustment path of the slider can be set according to a rotation of the output nut by an angle of rotation in the range between 20° and 45°, specifically that an angle of rotation of 23°, 25°, 30°, 35°, 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 angles of rotation depending on the lock type. By simply varying the sliding piece on the slider using the pre-fabricated mounting points, the appropriate angle of rotation for the corresponding door lock can be set without requiring a new design or redesign of the anti-panic push bar.This significantly reduces the variety of variants in the manufacture of the anti-panic push bar.

[0015] In one embodiment, a sliding element can be made of a plastic, in particular POM (polyoxymethylene) or PTFE (polytetrafluoroethylene). Making the sliding elements from a mechanically resistant yet low-friction plastic improves the bearing of the slider in the groove. In practice, the groove is made of 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 the resulting friction generated when the anti-panic push rod is actuated is negligible. Furthermore, the plastic sliding elements reduce noise, since sliding friction between plastic and metal produces significantly less noise than friction between two metal surfaces.

[0016] In particular, it may be provided that the base profile is made of a metal, especially steel or aluminium, and / or that the slider is made of a metal, especially steel and / or aluminium and / or plastic.

[0017] In an advantageous embodiment, the slide can be designed as a three-part slide, comprising a central slide section and two outer slide sections that are connected to each other. The use of a multi-part slide further simplifies the manufacture of the anti-panic push bar. To achieve different lengths, it is not necessary to use a new slide section each time; rather, it suffices to modify one of the three sections according to its length.

[0018] In an advantageous embodiment, the three parts of the slide can be separated from one another. By making the parts of the slide separable or connectable, the installation of the long slide in the profile is correspondingly simplified, since the short parts can be inserted into the groove and then easily connected, for example by screwing or snapping them together. This significantly simplifies handling compared to using a single-piece long slide.

[0019] Advantageously, the central slide section can be designed to run outside the groove supporting the slide, specifically above the groove and / or above the gap. By having the central slide section run outside the groove, the resulting friction is further reduced. Since the central section essentially runs freely in the air, it is not subject to any restrictive friction. Furthermore, no disruptive scraping noises can occur at this point when the slide is actuated. Only the two outer slide sections are guided in the groove. These two outer slide sections can be mounted with minimal friction and noise via the sliding blocks.

[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 longitudinally along the base profile, and in particular as a continuous groove.

[0021] In one embodiment, the transverse extent of the central slide section can be smaller than the clear width of the gap and / or groove. By making the transverse extent of the central slide section smaller than the width of the gap, a particularly low overall height can be achieved. This allows the central slide section to be guided outside the groove but still within the gap, such that the central slide section does not touch either a wall of the groove or a boundary wall of the gap, i.e., it is guided in the air.

[0022] Advantageously, the central slide section can be provided with a grid of holes to allow for variable adjustment of the slide's length, in particular a regular grid of holes with a pitch in the range of 8 mm to 12 mm, preferably with a pitch of 10 mm. The length of a screw connection between the central slide section and one of the outer slide sections can be adjusted via this grid dimension by adjusting the connection between the central and outer slide sections according to the required length. This makes it possible to use one and the same slide 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 number of variants.To achieve a greater range of variability, the slider can also be shortened by reducing the length of the middle section. For example, the middle section can be shortened by the required amount, preferably by sawing, to adapt an anti-panic push bar for 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 on ships or in railway vehicles for emergency exit doors.

[0024] The figures show further embodiments of the invention, which are described below. These include: 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 view of the anti-panic push bar made of Fig. 2 ; Figs. 4 and 5: a detailed enlargement in the area of ​​the actuating levers of the anti-panic push rod; Figs. 6 and 7: a schematic representation of the multi-part slide.

[0025] The embodiments shown in the figures are exemplary and should not be understood as limiting. Features functioning identically have been designated with the same reference symbols. It is obvious to a person skilled in the art that, within the scope of their technical expertise and the application of the patent claims, they can combine the embodiments shown in the figures without infringing upon the scope of protection afforded by the claims.

[0026] The Fig. 1 Figure 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 pivotally mounted on hinges 131 and 132, which is attached to a door frame 13. A mortise lock 14 is arranged in the door leaf 12, which interacts with the anti-panic push bar 2. The mortise lock 14 can, for example, be designed 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] Emergency exit door 11 is locked via an emergency exit door opener 18. Normally, the emergency exit door opener 18 is locked and prevents unauthorized opening of emergency exit door 11. The emergency exit door opener 18 can be unlocked, for example, via an access control device to allow an authorized person to open emergency exit door 11. The person's authorization can be verified, for example, by a transponder, RFID, or key.

[0029] In the event of an emergency, pressing the emergency button 15 triggers an alarm and unlocks the door opener 17. The alarm transmitter 16 then generates an alarm signal, and the emergency exit door 11 is unlocked for everyone to open. Subsequently, pressing the actuation profile 21 of the anti-panic push bar 2 unlocks the door lock 14, and the emergency exit door 11 can be opened by swinging 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, to the electronic bus 17, or to connect an escape route control system or to connect other components, such as an access control device, in order to electrically switch and / or block the escape door 11.

[0031] The Fig. 2 Figure 1 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. An actuating handle 21 in the form of the actuating profile 21 is formed on the front of the anti-panic push bar 2. To trigger the anti-panic push bar 2, pressure is exerted on the actuating profile 21, whereupon it is moved towards the base profile 22 along the illustrated direction of movement 7.

[0032] A transmission device 26 transfers the movement of the actuating handle 21 to a sliding device 23 located on the base of the base profile 22. The sliding device 23 comprises at least one slide 4. The slide 4 is guided so as to be translationally displaceable within a groove 24 in the base region of the base profile 22. That is, 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 for this purpose, which transmit the movement of the actuating handle 21 to the slide 4.

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

[0034] Both the base profile 22 and the actuating handle 21 are designed as U-shaped profiles 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 an installation space in which the mechanical and / or electrical components of the anti-panic push rod 2 are housed.

[0035] Slider 4 is in a Nut 24 is guided over sliding pieces 31, 32, 33, 34. The groove 24 is open to the interior of the base profile 22. Nut 24 trained by the Nut 24 has a gap 243. The sliding pieces 31, 32, 33, 34 extend through the gap 243 to guide the slide 4 linearly.

[0036] The sliding pieces 31, 32, 33, 34 are connected to the top of the slide 4, i.e., to the side of the slide 4 facing the installation space. The slide 4 has several attachment points 441, 442 on its top surface for securing the sliding pieces 31, 32, 33, 34. The number of sliding pieces and attachment points is variable; that is, 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 one attachment point 441, 442, etc. In particular, the slide 4 has more attachment points than sliding pieces.

[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 repositioned and attached to new mounting points. This makes it possible, for example, to shorten the slider 4, preferably by sawing or cutting it, 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 slide 4 is guided translationally in the groove 24 of the base profile by means of the sliding pieces 31, 32, 33, 34. The clearance of the slide 4 in the groove is designed to be greater than the clearance 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, thus reducing friction. The slide 4 is a multi-part design, comprising two outer parts 41 and 43 and a central part 42. The central part 42 is screwed to the outer parts 41 and 43 by means of screws 422. The middle slider part 42 has a hole pattern 421 to allow adjustment of the length between the two outer slider parts 41, 43 of the slider 4.The screw connection can be varied using the screws 422 according to the required length of the slider 4 by means of the hole grid 421 in order to adjust the overall length of the slider 4.

[0040] In the Fig. 3 A cross-sectional enlargement in the area of ​​the guide for the slide 4 is shown. The base profile 22 is U-shaped and has a guide groove 24 in its base for the translational guidance of the slide 4. The groove 24 comprises two side walls 241, 242, each of which encompasses 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 implemented with an L-shaped cross-section. In the illustration of the Fig. 3 The outer part 41 of the slide 4 can be seen, which is connected to the middle slide 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 guided only at its two outer slide parts 41 and 43. The middle slide part 42 essentially runs in the air and has no contact with the side walls 241 and 242 of the groove 24. Therefore, no friction can occur 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. Fig. 3 The sliding piece 32 is shown as an example. The sliding pieces extend through the gap 243 and are dimensioned such that their transverse dimensions engage positively in the gap 243. This means that the sliding pieces 31, 32, 33, 34 are positively engaged and linearly displaceable within the gap 243. The sliding pieces 31, 32, 33, 34 have a stop 35 or a rib 35 on their upper side. This stop limits the translational movement of the slide 4. The stroke of the actuating profile 21 can thus be adjusted. The resulting rotational movement of the output socket 25 can also be adjusted accordingly. Depending on the position of the corresponding sliding piece on the slide 4, a larger or smaller rotational angle of the output socket 25 can be achieved.

[0043] In Fig. 4 A detailed enlargement of the anti-panic pushrod 2 in the area of ​​the first lever 261 of the transmission device 26 is shown. The lever 261 interacts with the first outer slide part 41 to move the slide 4 translationally along the base profile 22. On the in Fig. 4 The two sliding pieces 31 and 32 are mounted on the outer slide part 41 shown, i.e., received in their corresponding mounting points. An unoccupied mounting point 441 is shown in Fig. 4 also visible.

[0044] In the Fig. 5 A detailed enlargement of the area of ​​the second lever 262 of the transmission device 26 is shown. The transmission lever 262 interacts 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 bridge 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 into the Fig. 5 The sliding direction shown is 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 drive, this results in a correspondingly larger or smaller rotational movement of the output nut. In this way, it is possible to connect the anti-panic push bar to different rotational angles of a door lock. For example, the translational path of the slide can be adjusted by repositioning the sliding pieces so that rotational angles in the range of 20° to 45° can be covered. Discrete rotational angles can be set, for example, 20°, 23°, 25°, 30°, 35°, 40°, and 45°.These values ​​are merely examples and can of course be varied according to the circumstances by prefabricating the mounting points 441, 442 of the slide 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, as well as the middle slide part 42 connecting them. The middle slide part 42 has a grid of holes 421 for screwing it to the two outer slide parts 41 and 43 using screws 422. By selecting different mounting 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 any components, for example, by cutting them to length.

[0046] In the Fig. 7Figure 1 shows an exploded view of the assembly of the central slide section 42 to the two outer slide sections 41 and 43. The two outer slide sections 41 and 43 are inserted into the groove 24 of the base profile 22 and moved into their outer positions. The central slide section 42 is then inserted and screwed to the outer slide section 41 and to the outer slide section 43 using screws 422. This type of assembly simplifies the installation of the anti-panic push bar 2, as the entire slide 4 does not need to be inserted into the groove 24, which is formed as a continuous groove on the base profile 22.

[0047] One advantage is that the central sliding part 42 does not contact the groove 24, thus preventing friction and disruptive noise at this point. This reduces the actuation forces required to activate the anti-panic pushrod. Another advantage is that jamming cannot occur at this point. Reference symbol list
