Description

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

[0002] In practice, such anti-panic push bars are used in escape routes to ensure that a door can be opened in case of an emergency.

[0003] Such an anti-panic push bar is known from DE 10 2016 104 765 A1. This anti-panic push bar has a base profile that can be mounted on top of a door leaf. An actuating profile, movable relative to the base profile, releases the door lock when pressure is applied. This ensures that even in a panic situation, i.e., when many people are pushing towards a door, the door cannot jam but opens due to the pressure.

[0004] Furthermore, DE 10 2013 000 285 A1 describes a corresponding anti-panic push bar.

[0005] The object of the present invention is to provide an anti-panic push bar for escape doors or emergency exit doors that is universally applicable and cost-effective to manufacture. In particular, the anti-panic push bar should allow for a large number of variations without requiring the development of a separate model for each variation.

[0006] This problem is solved according to the invention by an anti-panic push bar with the features of claim 1.

[0007] Furthermore, this problem is solved according to the invention by a manufacturing process for an anti-panic push bar with the features of claim 12.

[0008] 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 drive nut that can be actuated by the actuating profile for actuating a door lock, further comprising a transmission device for transmitting a movement of the actuating profile to the drive nut. Essentially, the base profile has an outer shell and an inner shell such that the inner shell is arranged within the outer shell in such a way that the outer shell covers the externally visible surfaces of the inner shell.

[0009] The inventive concept also includes a manufacturing method for an anti-panic push bar for actuating a door lock of an escape door or emergency exit door, wherein the anti-panic push bar comprises: 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 drive nut that can be actuated by the actuating profile for actuating a door lock, further comprising a transmission device for transmitting a movement of the actuating profile to the drive nut. It is essential that an inner shell and an outer shell are manufactured separately, and that the inner shell is then positively inserted into and / or connected to the outer shell to form the base profile.

[0010] In particular, the outer shell and the inner shell are held together by a positive fit. Preferably, the inner surface of the outer shell rests directly on and covers the outer surface of the inner shell.

[0011] Specifically, the positive fit between the outer and inner shells refers to the fact that the outer shell is held and positioned on the inner shell by its precise geometry and shape. This positive fit can be designed so that no additional fasteners such as screws or adhesives are necessary. It is a principle based on the positive connection of shapes. Nevertheless, additional fasteners such as screws, rivets, or adhesives can be used to create a mechanically secure connection.

[0012] A positive fit occurs when two parts interlock in such a way that they can no longer move relative to each other in one or more directions. You can imagine it like a puzzle piece that fits into a matching hole.

[0013] As part of the interlocking design, the outer shell can also be provided with special contours, grooves, or recesses that fit precisely with corresponding features on the inner shell. This allows for simple and secure assembly by sliding or snapping the parts together, simplifying manufacturing and maintenance. The outer and inner shells are thus not only held together but also precisely aligned.

[0014] The two-part design of the base profile, with an inner and an outer shell, offers the advantage of allowing for individual customization to meet specific requirements. The inner shell can act as a component carrier, accommodating and supporting the components of the panic bar. The outer shell determines the surface finish of the panic bar and / or its mechanical resistance. This allows, for example, the stability of the panic bar to be adjusted by appropriately combining the inner and outer shells, or the surface finish of the panic bar to be varied according to the surface finish of the outer shell. In this way, the design and / or the mechanical and / or corrosion resistance requirements of an panic bar can be easily selected or modified.

[0015] The base profile can form a supporting housing for the panic bar. The housing can include a receiving space for components of the panic bar. In particular, the base profile is designed in two parts. That is, the base profile has a wall or profile that is designed in such a way that it consists of an inner shell and an outer shell. The outer shell, together with the inner shell, forms the two-part base profile.

[0016] The base profile can be U-shaped. The outer shell can be designed to complement the inner shell. In particular, the dimensions of the outer and inner shells are coordinated such that the outer shell can fit snugly around the inner shell and visually conceal it. This means that the shape and dimensions of the outer shell are matched to the shape and dimensions of the inner shell so that the outer shell rests directly on the inner shell. In particular, the outer shell extends over the entire surface of the inner shell, especially the entire visible surface of the inner shell. This ensures that the inner shell is covered and visually concealed by the outer shell.

[0017] Preferably, the inner shell forms the structural core of the housing. Its primary function is to securely enclose the mechanical and / or electromechanical components of the panic bar or pushbar and to absorb the forces exerted on the panic bar or pushbar. The mechanical components may include, for example, a locking mechanism, springs, sliders or linkages, and / or gear components. The electromechanical components may include a drive, such as an electric motor or an electromagnet, as well as associated control electronics or sensors.

[0018] In particular, a robust material such as steel, aluminum, or a high-strength technical polymer (e.g., glass fiber reinforced plastic) is used for the inner shell. These materials ensure the necessary mechanical strength and durability.

[0019] Preferably, the inner shell is precisely formed, i.e., with low manufacturing tolerances, to accommodate all internal components perfectly. The inner shell may have attachment points for mounting to the door and for accommodating mechanical and / or electromechanical components of the panic bar or push bar, or for connection to the outer shell. Its surface may be untreated, as it is not visible.

[0020] In particular, the inner shell can serve as a mechanical support and protects the internal mechanisms from dirt and damage.

[0021] The outer shell encases the inner shell and is the visible part of the panic bar or push bar. One function of the outer shell is to achieve the desired aesthetic and visually integrate the panic bar or push bar into the door design.

[0022] Various materials can be used for the outer shell, all of which are visually appealing and pleasant to the touch. Examples include stainless steel, anodized aluminum, brass, or even plastics with special surface coatings. The outer shell material can be particularly weather-resistant and corrosion-resistant.

[0023] In particular, the outer shell is designed to overlap and enclose the inner shell, without compromising functionality. It can feature various colors, textures, or surface structures.

[0024] This separation of load-bearing and decorative components not only simplifies manufacturing but also adaptation to different markets and design requirements, as the inner shell can serve as a universal base for various outer shell designs.

[0025] This design allows the inner shell to form the invisible, load-bearing backbone, while the outer shell provides the visible, customizable surface of the panic bar or push bar. This division enables efficient and cost-effective manufacturing of the mechanical components and flexible design adaptation.

[0026] In particular, it can be provided that several outer shells, each with a different surface finish, are manufactured for an inner shell, and that from these multiple outer shells, one with a specific surface finish is selected and joined to the inner shell to form a basic profile with that specific surface finish. This significantly simplifies manufacturing by prefabricating and stockpiling a selection of different outer shells for a given inner shell or type of inner shell. If an anti-panic push bar with the corresponding surface finish is ordered, the inner shell can be joined to the appropriate outer shell to create and deliver the anti-panic push bar with that specific surface finish.

[0027] Similarly, the actuating profile can also be constructed in two parts. For the actuating profile, an inner actuating shell and an outer actuating shell can be manufactured separately, with the inner actuating shell then being positively inserted into and / or connected to the outer actuating shell to form the actuating profile. In this way, it is possible to design the complete housing of the panic bar according to the inventive concept, in particular to manufacture the basic profile with a specific outer shell and an inner shell, as well as to manufacture the actuating profile with an inner actuating shell and a specific outer actuating shell, such that a specific surface of the panic bar can be produced in a simple manner.In particular, this prevents the housing of the anti-panic push bar from having to be redesigned for every desired surface, since, according to the inventive idea, it is sufficient to simply design the outer shells accordingly.

[0028] Accordingly, it may be provided that several outer actuation shells, each with different surfaces, are manufactured for an inner actuation shell, and that from the several outer actuation shells an actuation shell with a specific surface is specifically selected and connected to the inner actuation shell in order to form an actuation profile with a specific surface.

[0029] To ensure a mechanically stable construction of the anti-panic push bar, it may be provided that the inner shell is positively engaged in the outer shell, preferably that the inner shell is positively engaged and / or force-fitted in the outer shell, in particular by gluing and / or welding, and / or riveting.

[0030] The positive locking or force-fit connection between the inner shell and outer shell significantly improves the mechanical strength of the housing of the anti-panic push bar, enabling it to withstand increased forces.

[0031] In one embodiment, the inner and outer shells may have a U-shaped cross-section such that two legs, open on one side, are connected to each other on the other side via a base surface. This allows for a typical housing design of the anti-panic push bar, such that the base profile supports the actuating profile, for example, by having the two legs of the base profile receive the actuating profile, so that the latter can be actuated into or onto the base profile.

[0032] Preferably, the two legs of the outer shell can be longer than the two legs of the inner shell. This ensures that the legs of the outer shell with the desired surface completely cover the legs of the inner shell, so that only the surface of the outer shell is visible from the outside.

[0033] Alternatively or additionally, the upper end areas of the two legs of the outer shell can be bent inwards. This further improves the appearance, ensuring that the inner shell is covered even when viewed from above.

[0034] It is also possible to design the upper end regions of the two legs of the outer shell with an inwardly thickened wall thickness to cover the two legs of the inner shell. This increased wall thickness of the outer shell also makes it possible to visually conceal the inner shell.

[0035] Preferably, the inner shell may be made of aluminum or an aluminum alloy.

[0036] In a preferred embodiment, the inner shell can have receptacles and / or bearings for components of the transmission device, in particular for slides and / or levers and / or gears of the transmission device.

[0037] To create variable surfaces, for example, the outer shell can be made of or consist of a surface of stainless steel, brass, nickel, chrome, gold, anodized aluminum, plastic.

[0038] The actuation profile can be constructed analogously to the basic profile; in particular, it can be provided that the actuation profile has an inner actuation shell and an outer actuation shell.

[0039] Preferably, the inner actuating shell can be positively engaged in the outer actuating shell, preferably the inner actuating shell can be positively engaged and / or force-fitted in the outer actuating shell, in particular by being glued and / or welded, and / or riveted.

[0040] In a preferred embodiment, it can be provided that the inner actuating shell and the outer actuating shell have a U-shaped cross-section, in particular with two legs open on one side and a base surface connecting them.

[0041] In a simple-to-manufacture variant, it can be provided that the inner actuating shell is made of aluminium, and / or that the outer actuating shell has a surface made of stainless steel, brass, nickel, chromium, gold, anodized aluminium, or plastic, or consists of one of these materials.

[0042] A further improvement in the applicability of the panic bar is achieved by providing, in a preferred embodiment, that the base profile and / or the actuating profile are designed to be cut to length. In particular, the inner shell inserted into the outer shell can be cut to length together in a single operation, and / or the inner actuating shell inserted into the outer operating shell can be cut to length together in a single operation. Cutting the panic bar to length allows it to be adapted to different door widths. This further reduces the number of prefabricated versions of the panic bar.

[0043] It is clear to the person skilled in the art that the features of the device described herein also apply to the manufacturing process and vice versa.

[0044] One application of the anti-panic push bar according to the invention is in escape and rescue route devices for building doors. These can be single-leaf as well as double-leaf 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, in corresponding escape and / or rescue doors.

[0045] The figures show further embodiments of the invention, which are described below. These include: Fig. 1: An escape route device of an anti-panic push bar according to the invention; Fig. 2: A schematic sectional view of an anti-panic push bar according to the invention; Fig. 3: A sectional view of the base profile of the anti-panic push bar according to the invention; Fig. 4: A schematic 3D representation of the base profile; Fig. 5: A schematic sectional view of the actuating profile of an anti-panic push bar according to the invention; Fig. 6: A schematic 3D representation of the actuating profile.

[0046] The designs shown in the figures are exemplary and should not be understood as restrictive.

[0047] Features with the same function are provided 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 validity of the patent claims, they can combine the embodiments shown in the figures without exceeding the scope of protection afforded by the patent claims.

[0048] 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.

[0049] 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 a display or indicator 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 device, i.e., without an electrical connection.

[0050] Emergency exit door 11 is locked via a switchable emergency exit lock 18. Normally, the emergency exit lock 18 is locked and prevents unauthorized opening of emergency exit door 11. The emergency exit lock 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.

[0051] In the event of an emergency, pressing the emergency button 15 can trigger an alarm and unlock the emergency exit lock 18. The alarm transmitter 16 then generates an alarm signal, and the emergency exit 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 11 can be opened by swinging the door leaf 12.

[0052] 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.

[0053] The Fig. 2Figure 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 4, which can be mounted on a door leaf, for example by screwing or gluing. The base profile 4 forms, so to speak, the back of the anti-panic push bar 2. An actuating handle 3 in the form of the actuating profile 3 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 3, whereupon it is moved towards the base profile 4 along the actuating direction 5 shown. The anti-panic push bar 2 has a cover cap 24 and 25 on each side, which close off the sides of the anti-panic push bar 2.

[0054] By means of a transmission device 21, this movement of the actuating profile 3 is transmitted to a slide device 22 arranged on the base of the base profile 4. The slide device 22 comprises at least one slide. The at least one slide is guided translationally displaceably within a groove 411 in the base region of the base profile 4. That is, the slide can be displaced along the longitudinal direction of the base profile 4. For this purpose, the transmission device 21 has two levers 211 and 212, each of which is held in the base profile 4 by a bracket 412. The levers 211 and 212 are each slidably mounted in a bearing 311 on the actuating profile 3. The bearing 311 is designed as a groove in which the levers 211 and 212 are slidably mounted by means of a pin. The levers 211 and 212 are slidably mounted on the actuating profile 3.212 are rotated about a pivot axis arranged in the console 412 when the actuating profile 3 is actuated and transmit the movement of the actuating profile 3 to the slide.

[0055] The slide is connected to an output socket 23 via a nut drive. The translational movement of the slide is converted into a rotary movement by means of the nut drive to drive the output socket 23. The output socket 23 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.

[0056] Both the base profile 4 and the actuating profile 3 are designed as U-shaped profiles in cross-section. The open side walls of the two profiles face each other. The actuating profile 3 is guided within the base profile 4. Together, the base profile 4 and the actuating profile 3 form an installation space in which the mechanical and / or electromechanical and / or electrical and / or electronic components of the anti-panic push bar 2 are housed.

[0057] The Figures 3 and 4 The basic profile 4 of the anti-panic push bar 2 is shown. Fig. 3 shows a section of the basic profile 4. In the Fig. 4 A schematic 3D representation of the basic profile is shown.

[0058] The base profile 4 has an inner shell 41 and an outer shell 42. The inner shell 41 is made of aluminum, in particular an aluminum alloy. Mounting points or bearings for components of the panic bar 2 are arranged in the inner shell. Mechanical components, such as gear elements and / or levers, can be mounted in these receptacles or bearings. However, they can also be mounting points for electrical or electronic components of the panic bar. The drawings show three grooves 411 in the base area, in which a sliding device of the panic bar 2 is received. Actuation of the actuating profile 3 can be transmitted to the output nut 23 via the sliding device.

[0059] The inner shell 41 is positively fitted into an outer shell 42. An adhesive layer can be placed between the outer shell 42 and the inner shell 41 to force-fit the two shells 41 and 42 together. The inner shell 41 has a U-shaped cross-section, meaning it has two upward-facing legs, the first leg 413 and the second leg 414. Similarly, the outer shell 42 is U-shaped and has two upward-facing legs, the first leg 43 and the second leg 44. The base profile 4 is closed at the bottom by a base surface 45. When the anti-panic push bar 2 is installed, the base surface 45 rests on a door leaf.

[0060] The outer shell 42 is made of a metal or plastic and has a visible surface. This visible surface can be made of, for example, chrome, nickel, aluminum, a plastic, or an anodized finish. The wall thickness of the outer shell can be between 0.1 mm and 0.8 mm, preferably between 0.2 mm and 0.5 mm. By selecting a suitable outer shell 42, the surface finish of the panic bar 2 can be precisely defined. An advantage is that no redesign of the base profile 4 is necessary, since the inner shell 41 serves as the functional carrier for the components of the panic bar 2 and does not need to be replaced. The outer shell 42 serves only as an optical covering and provides mechanical reinforcement for the inner shell 41. No components of the panic bar 2 are mounted on the outer shell.

[0061] To cover the inner shell 41 all around, as in Fig. 4 The upper portion of the first leg 43 of the outer shell 42 and the second leg 44 of the outer shell 42 are bent inwards. The bent portion is marked with the reference symbols 431 and 441, respectively. This ensures that the inner shell 41 is completely covered, even when viewed from above. The actuating profile 3 is accommodated in the free space between the bent upper edges 431 and 441, so that the inner shell 41 is not visible from the outside when the anti-panic push bar 2 is fully installed.

[0062] In the Figures 5 and 6 The activity profile 3 is shown. Fig. 5 shows a cross-section through actuation profile 3. The Fig. 6 Figure 3 shows a schematic three-dimensional representation of the actuation profile.

[0063] The actuating profile 3 has an inner actuating shell 31 and an outer actuating shell 32. The inner actuating shell 31 is positively fitted into the outer actuating shell 32. An adhesive layer can be arranged between the inner actuating shell 31 and the outer actuating shell 32 to force-fit the two shells 31 and 32 together.

[0064] The actuating profile 3 has a U-shaped cross-section. Accordingly, the inner actuating shell 31 has a first leg 312 and a second leg 313. Similarly, the outer actuating shell 32 has a first leg 33 and a second leg 34. At the top of the actuating profile 3, the legs are connected to each other by a base surface 35 and a base surface 314, respectively.

[0065] The inner actuating shell 31 houses functional components of the anti-panic push bar 2. For this purpose, the inner actuating shell 31 has a bearing 311 in the form of a groove in the area of ​​its base 314. The levers 211 and 212 of the transmission device 21 are slidably mounted in the groove 311 via pins. When pressure is applied to the actuating profile 3, it moves towards the base profile 4 in the actuating direction 5. During this movement, the two levers 211 and 212 are rotated and move along the groove 311.

[0066] The inner actuating shell 31 serves to house functional components of the panic bar 2. The outer actuating shell 32 serves to visually conceal the inner actuating shell 31. The outer actuating shell 32 is manufactured with different surface finishes. In particular, it is intended to produce a selection of different outer actuating shells 32, each with a different surface finish. For example, the surface finish could be chrome-plated, plastic, nickel-plated, anodized, painted, or coated. Therefore, to produce a panic bar with a specific surface finish, it is sufficient to provide the same inner actuating shell 31 with the corresponding outer actuating shell 32, which has the desired surface finish.

[0067] Normally, an operating outer shell 32 is selected which has the same surface as the outer shell 42 of the base profile 4.

[0068] To completely conceal the inner actuating shell 31, the two legs 33 and 34 of the outer actuating shell 32 are longer than the two legs 312 and 313 of the inner actuating shell 31. This ensures that only the surface of the outer actuating shell 32 is visible from the outside. This makes it possible to easily produce a wide variety of anti-panic push bar 2 variants without having to develop a completely new housing for each variant. Reference symbol list
