Description

[0001] The invention relates to a revolving door with a turnstile arranged between opposing drum elements and with a ceiling assembly arranged on the upper side of the drum elements and on which the turnstile is rotatably mounted. STATE OF THE ART

[0002] From DE 100 50 027 C1, a revolving door is known with a rotating mechanism rotatably mounted between two drum elements, wherein a ceiling assembly is provided that closes off the upper side of the pedestrian area of ​​the revolving door. The rotating mechanism has several leaf elements whose upper edges extend under the stationary ceiling assembly. Brush elements are often attached to the upper side of the leaf elements, which rub against the underside of the ceiling assembly to provide a sealing effect.

[0003] For example, EP 2 754 821 A2 discloses a revolving door with a rotating mechanism mounted between two drum elements and a ceiling assembly, wherein the ceiling assembly, particularly in conjunction with a drive motor, incorporates lighting elements to illuminate the pedestrian area of ​​the revolving door. A stationary suspended ceiling element is provided on the ceiling assembly, which is statically connected to a pre-fixing device for receiving the drive motor.

[0004] EP 3 034 759 A1 discloses a revolving door with a turnstile arranged between opposing drum elements, wherein a ceiling assembly closes off the top of the revolving door and to which the turnstile is rotatably mounted. A light source is arranged around the drive motor, which is gearless and connected to the turnstile, to illuminate the pedestrian area of ​​the revolving door. The ceiling element has flat glass panels, and brush elements are also attached to the upper side of the turnstile's wing elements, which rub against the underside of the glass elements when the turnstile is set in rotation.

[0005] DE 198 21 789 A1 shows a revolving door with a rotating wing driven by a drive unit between two diametrically opposed drum walls, which are interrupted by an entrance and exit, with a rotating ceiling, wherein an electronic control unit containing at least one microprocessor is provided for controlling the drive unit, which is activated on the basis of a sensor signal detected outside the rotation range of the rotating wings, and that additionally sensors are provided within the rotation range of the rotating wings, the signals of which are used for speed control of the rotating wings.

[0006] DE 44 22 454 A1 discloses a door consisting of four leaves. A roof section is attached to each leaf, which participates in the door's rotational movement. The roof sections are attached to the leaves near their outer ends with screws. REVELATION OF THE INVENTION

[0007] The object of the invention is to simplify the construction of a revolving door with a rotating mechanism arranged between opposing drum elements, whereby a ceiling assembly of the simplest possible design is to be provided, and wherein the transition between the rotating mechanism, in particular the wing elements, and the ceiling assembly is to be improved. A further object of the invention is to improve the appearance and / or functionality of the revolving door as a whole.

[0008] This problem is solved starting from a revolving door according to the preamble of claim 1 in conjunction with the characterizing features. Advantageous embodiments of the invention are specified in the dependent claims.

[0009] The invention includes the technical teaching that a ceiling device is arranged to rotate with the turnstile.

[0010] The ceiling mechanism rotates in sync with the rotation of the revolving door and is rigidly connected to it, forming a single unit that can rotate between the drum elements. The ceiling mechanism is located adjacent to the underside of the ceiling assembly, and a gap may exist between the two. This allows the ceiling assembly to have an underside equipped with structural and functional elements, without requiring any cladding or aesthetic considerations, as the ceiling mechanism is what ultimately forms the visible upper surface of the revolving door from the pedestrian area.It is particularly advantageous if the ceiling fixture and the ceiling assembly are designed to be parallel to each other, with the ceiling fixture being able to extend in at least one or more planes; it is also conceivable that the ceiling assembly has areas that have different distances to the ceiling fixture.

[0011] Furthermore, the rotating ceiling mechanism offers the advantage that no visible brush seal, and therefore none accessible for air exchange, is required at the top of the revolving mechanism. In this case, either no brush seal would be present at the top of the revolving mechanism at all, or it would be concealed above the ceiling mechanism, thus reducing heat loss. This increases the energy efficiency of the revolving door.

[0012] The terms "top" and "upper area" refer specifically to the installed state of the door.

[0013] In particular, the ceiling device can completely cover the underside of the ceiling assembly, wherein the ceiling device preferably has a diameter that substantially matches the diameter of the ceiling assembly. The deviation of the diameter of the ceiling assembly from the diameter of the ceiling device can, for example, be less than 50%, preferably less than 20%, and particularly preferably less than 5%, and more specifically less than 3%. In particular, the ceiling device can have a diameter with which it substantially completely covers the underside of the ceiling assembly, so that the underside of the ceiling assembly is no longer visible to a person walking on it. In any case, the diameter of the ceiling device can be determined such that the ceiling assembly remains visible only from a side perspective.

[0014] The turnstile can have several wing elements, for example, two, three, or four wing elements, with the ceiling assembly comprising sections arranged between the wing elements at the upper end of the turnstile, in particular at one end, pointing towards the ceiling assembly. The upper area of ​​the turnstile can refer to, in particular, the area of ​​up to 30%, 20%, 10%, 5%, or 3%. It is also possible to arrange the sections on top of the wing elements, or the ceiling assembly can be designed as a flat circular disc and placed on top of the wing elements, for example, with a central opening to connect a central column of the turnstile to a motor in the ceiling assembly. It is also possible for the ceiling assembly to be designed in two parts, in particular comprising two semicircles.Some of the sections can be positioned above the turnstile and / or attached to an upper edge of the turnstile. Thus, the turnstile would visually or mechanically support the sections.

[0015] The sections can be connected to or attached to the wing elements by means of a force-fit, material-fit, and / or form-fit connection, and it can be provided that the sections form a stiffening structure for the wing elements and thus also for the turnstile as a whole. The number of sections can correspond to the number of wing elements of the turnstile.

[0016] Thus, it is possible that the segments, when arranged on the wing elements, form a structure that aligns the wing elements to each other and / or stiffens them.

[0017] A particular advantage of the ceiling fixture is that it includes at least one light source. It is also conceivable that the ceiling fixture includes a sensor, a monitoring device, a blocking device to prevent the rotation of the turnstile, or, for example, a loudspeaker or fragrance diffuser.

[0018] Furthermore, the ceiling fixture may have at least one translucent section, for example, in the form of an inner, approximately central, or radially outer ring-shaped section, such that at least one light source is arranged on or in the underside of the ceiling assembly and, when the light source is in operation, illuminates the translucent section. The translucent section may be formed, in particular, by a recess in the ceiling fixture and / or a cover. The translucent section may, for example, have a frosted structure or surface, in particular in the form of frosted glass or a milky plastic. The translucent section may be unidirectionally transparent, bidirectionally transparent, and / or partially transparent.In particular, with unidirectional designs, the light source on the ceiling assembly can be covered or hidden by the translucent section, which can still be illuminated when the light source is in operation.

[0019] Preferably, a sensor can be integrated into or attached to the ceiling device, whereby the sensor is arranged to rotate with the rotary movement of the turnstile.

[0020] Alternatively, it is also conceivable that a sensor is installed on the underside or side of the ceiling assembly and that the sensor function can take place through the ceiling assembly, for example based on a radar system and / or an optical system that operates in a wavelength range for which, for example, a translucent sub-area can also be penetrated, which may consist of plastic or glass.

[0021] The ceiling fixture can extend in one, in particular a flat and / or single plane, or it is possible that the ceiling fixture has an exterior area away from a rotation axis of the turnstile, which extends in an upper plane, in particular towards the ceiling brewing unit, and an interior area facing the rotation axis of the turnstile, which extends in a lower plane facing the turnstile.

[0022] The cross-section of the otherwise plate-shaped or planar ceiling element can therefore be designed as a deep-drawn part or as a multi-part component, especially if the ceiling system is made up of several sections. These sections can also have a different plane on the inside than on the outside, so that they are, for example, S-shaped in cross-section.

[0023] The sections and / or the ceiling assembly, in particular a single-piece assembly, can be made of a metal sheet, in particular an aluminum sheet or a steel sheet, or it is provided that the sections or the entire ceiling assembly are made of plastic panels, wooden panels and / or glass panels.

[0024] The ceiling assembly and / or its components can be screwed or glued to the wing elements, or they can be connected to the components by frictional and / or form-fitting means, for example, by crimping, pressing, or clamping on, in, or between the wing elements of the turnstile. Furthermore, a drive motor, particularly for rotating the turnstile, is provided, which is located between the ceiling assembly and the ceiling assembly. In particular, the drive motor can be arranged on or in the underside of the ceiling assembly; for example, a rotor of the drive unit can protrude from the underside of the ceiling assembly, while the rest of the drive motor is located within the ceiling assembly. This advantageously allows the wing elements and / or, consequently, the ceiling assembly and, in particular, the components to be attached to the rotor of the drive motor.

[0025] For example, the thickness of the rotor can determine the distance between the ceiling fixture and the ceiling assembly, and the rotor of the drive motor simultaneously serves to form the upper bearing point of the turnstile, resulting in a particularly simple connection between the drive motor and the turnstile.

[0026] The ceiling assembly can have a thickness of no more than 20 cm, preferably no more than 15 cm, more preferably no more than 10 cm, more preferably no more than 8 cm, and even more preferably no more than 5 cm. Here, thickness is used synonymously with the height of the door when installed. "No more than" means "maximum" in this context.

[0027] The invention can be particularly advantageously implemented with a modular ceiling assembly having a sandwich structure, such that at least one filler is provided as the core material, and the filler has a cover plate on at least one or both cover surfaces. In this respect, only one top cover plate, only one bottom cover plate, or both a top and a bottom cover plate can be provided, preferably running parallel to each other with the filler located between them. It is also conceivable that further cover plates are present, penetrating the filler and forming, for example, an intermediate layer. An intermediate layer may be necessary, for example, to increase the stiffness of the ceiling assembly and to accommodate components within the ceiling assembly, to hold them in relation to each other, or to stiffen them together in their overall structure.The basic idea, however, envisages a sandwich construction that allows for a modularly manageable ceiling assembly which can be connected to the drum elements as a whole on site, in particular placed on top of the drum elements, preferably with rotatable mounting of the rotary cross between the drum elements.

[0028] The modular ceiling assembly thus results in a single, manageable unit that can be attached to and detached from the drum elements and the rotating mechanism. For example, the ceiling assembly can be pre-assembled at the factory so that it only needs to be connected to the drum elements and the rotating mechanism at the installation site, without having to assemble its basic components on-site. This significantly reduces assembly time and simplifies the overall design of the ceiling assembly. According to the invention, the ceiling assembly is designed as a module that can be attached to the other components of the revolving door, positioned on the drum walls and the rotating mechanism, and then removed from its position.

[0029] According to a further embodiment, the basic structure of the ceiling assembly provides that structural elements and / or functional elements are incorporated at least partially on or above the underside cover plate and / or on or above the upper cover plate, and particularly in the area of ​​the filler material. Naturally, structural elements and / or functional elements can also project laterally, in particular radially, or from the top or bottom of the cover plates. Specifically, the structural elements and / or functional elements can be surrounded by the filler material or embedded within it. For example, a disc motor for the rotatable drive of the rotary mechanism can be arranged on the underside of the ceiling assembly in such a way that it is, for instance, partially integrated within the ceiling assembly and partially protrudes from it.These types of motors are also known as torque or disc motors and are generally connected to the rotary table without a gear system. The same applies, for example, to connecting elements for linking the ceiling assembly to the drum elements or to upper structural elements of a building facade, which may also protrude from the basic structure of the ceiling assembly in sections.

[0030] The structural elements can, for example, traverse the ceiling assembly diametrically and / or connect the top and bottom cover plates, or be attached to only one cover plate. While the filler material is placed between the cover plates in such a way that it surrounds the structural elements and / or the functional elements, the structural elements and / or the functional elements can also subdivide the filler material into several sub-elements if, for example, the elements completely traverse the ceiling assembly. For the structural elements, a truss-like structure, a star-shaped structure, or, for example, a rectangular or hexagonal structure is conceivable in order to stiffen the ceiling assembly accordingly.

[0031] Furthermore, the underside cover plate, and optionally the upper cover plate as well, has openings, allowing functional elements to be arranged in conjunction with these openings. The optional openings in the upper and / or lower area of ​​the ceiling assembly, and optionally also in the lateral perimeter area, enable the on-site integration of functional elements, such as a drive, control unit, sensor device, lighting device, speaker device, power supply, locking mechanism, ventilation device, and / or the like, which can be inserted into the openings or into other recesses or intermediate areas in the filler material. Advantageously, the underside cover plate and / or the upper cover plate are bonded to the filler material by a material-bonded, force-fit, and / or form-fit connection.Preferably, at least one cover plate is bonded, soldered, and / or welded to the filler and / or optionally also to the structural elements and / or functional elements, whereby friction-fit or form-fit connections are also possible, for example, by pressing the cover plate against corresponding counter-elements, in particular in or on the filler, on the structural elements, and / or on the functional elements. It is also conceivable to connect the two opposing, spaced-apart cover plates with connecting elements in such a way that the sandwich composite is created and the ceiling assembly is formed as a separately handleable component.

[0032] The light source on the ceiling fixture or ceiling assembly can be used to emit light signals, in particular different light colors to indicate the recommended walking area or an area where the revolving door should not be entered. Alternatively, the light signals can be sequences, providing information to a person entering the revolving door about how to proceed. For example, the light signals can indicate whether the person is entering the revolving door before or after a rotating wing element, or they can indicate which areas on the floor of the revolving door are accessible without interrupting the rotation of the turnstile, which is monitored by sensors.In particular, the light source can be designed in conjunction with a control device of the revolving door.

[0033] It is also conceivable that at least one of the wing elements or one of the drum elements could have a display, in particular an LCD, for showing information. This would further improve the appearance and / or functionality of the revolving door.

[0034] It is also conceivable that the display is arranged on the glass plate such that it is enclosed by the transparent glass surface of the plate. Furthermore, it is conceivable that electrical foil conductors are arranged on the wing elements, by means of which the display is electrically contacted, preferably wherein the electrical foil conductors are arranged in a brush arrangement on a wing edge or on a central column of the rotary joint and are contacted at a rotary feedthrough. The rotary feedthrough can be designed as a slip ring. This improves the integration of the display into the wing element.

[0035] It is further conceivable that at least one of the wing elements comprises at least two glass plates arranged parallel to each other, with the display positioned between the glass plates, preferably with the glass plates being bonded together by means of a laminated film, wherein the display is integrated into the laminated film or arranged on or against the laminated film. This enables optimal integration.

[0036] It is also conceivable that the display is designed for interaction with a person, particularly via touch input, preferably allowing the interaction to stop and / or change the rotation speed of the revolving door. In particular, this allows an emergency stop of the rotation to be initiated by a person inside the revolving door. This is a significant improvement over conventional systems where an emergency stop function is only available from outside the revolving door. The safety of users can thus be increased even in unforeseen situations.

[0037] The display described in connection with the wing element can be designed analogously in connection with the drum element. PREFERRED EXAMPLE OF THE INVENTION

[0038] Further measures improving the invention are described in more detail below, together with a description of a preferred embodiment of the invention, with reference to the figures. The figures show: Figure 1 a perspective view of a revolving door with the features of the invention, Figure 2 the revolving door with the main components in a flying view, Figure 3 a perspective view of the revolving door with a section through the ceiling assembly and the ceiling device, Figure 4 a view of the revolving door with the wing elements and the ceiling device, which is formed from several parts, Figure 5 the view of a wing element with a display attached to it.

[0039] The embodiment of the revolving door 100 according to Figure 1The revolving door 100 has two opposing, curved drum elements 11, which are exemplified as glass elements, and between which a turnstile 10 is rotatably mounted, so that the revolving door 100 can be passed through by people between the drum elements 11. The revolving door 100 has a ceiling assembly 12 on its upper side, below which a ceiling device 13 is arranged. According to the invention, the ceiling device 13 is connected to the turnstile 10 such that the ceiling device 13 rotates with the turnstile 10. In particular, the ceiling device 13 has a fixed, preferably rigid, connection to the turnstile 10.

[0040] The example shows light source 16 as a flat component of the ceiling fixture 13, such that the accessible area of ​​the revolving door 100 is illuminated by the light source 16. The light source 16 can also perform signal functions, in particular to indicate accessible and inaccessible areas between the drum elements 11. For example, the light source 16 can be divided into a number of segments corresponding to the number of wing elements of the turnstile 10. Each segment of the turnstile 10 that can be individually accessed by people can thus be illuminated by the light source 16 in such a way that information about an accessible or inaccessible area is generated, for example by green or red light.

[0041] Figure 2Figure 1 shows an exemplary embodiment of the revolving door 100 with its essential components in a flying view. The drum elements 11 with the rotating mechanism 10 located between them are shown; this mechanism, for example, has four leaf elements 14. The ceiling assembly 12, which is connected to the upper sections of the drum elements 11 when the revolving door 100 is installed, is shown on the upper side. Below the ceiling assembly 12 is the ceiling device 13, which is either designed as a flat panel or, as shown in the example, has a pot- or plate-shaped recess.

[0042] The embodiment of the ceiling device 13 thus has a surrounding outer area 13a, which can be distinguished from an inner area 13b. The surrounding outer area 13a is formed in the direction of the ceiling assembly 12, and the inner area 13b is concave and is formed in the direction of the turnstile 10.

[0043] This creates an inner recess in the ceiling fixture 13, so that, viewed from the outside, the revolving door 100 has a very narrow upper section consisting of the ceiling assembly 12 and the ceiling fixture 13. Towards the central axis of rotation of the turnstile 10, the ceiling section thickens as the ceiling fixture 13 is shaped like a cup at the bottom. For example, a drive motor 20 can be accommodated in the space between the ceiling fixture 13 and the ceiling assembly 12 by positioning the drive motor 20 in the space created between the inner area 13b of the ceiling fixture 13 and the ceiling assembly 12. The ceiling fixture 13 is connected to the turnstile 10 in such a way that the ceiling fixture 13 rotates with the turnstile 10.Therefore, a remaining gap must be provided between the outer surface 13a of the ceiling assembly 13 and the underside of the ceiling assembly 12, which can, however, be small, for example with a clear gap dimension of between 1 mm and 20 mm. Advantageously, however, the upper surface of the assembly consisting of the ceiling assembly 12 and the ceiling assembly 13 appears very narrow, and the thickness only increases in the inner area of ​​the revolving door 100.

[0044] Figure 3 Figure 1 shows a perspective view of the revolving door 100 with a section through the ceiling assembly 12 and the ceiling fixture 13, with drum elements 11 shown on the front and back. The ceiling assembly 12 is located on the upper side and is shown transparently, so that the drive motor 20 and the ceiling fixture 13 are shown on the underside of the ceiling assembly 12.

[0045] Light sources 18 are arranged on the underside of the ceiling assembly 12, and in accordance with the radial position of the light sources 18, which are arranged in a circumferential manner, the ceiling assembly 13 has a transparent, translucent section 17. When the light sources 18 are operated, they can generate light through the section 17 and illuminate the accessible interior area of ​​the revolving door 100.

[0046] For example, sensors 19 are shown on the underside of the ceiling device 13, which can form safety devices for the operation of the revolving door 100.

[0047] The drive motor 20 has a rotor 21 which is rigidly connected to the ceiling device 13, and finally the wing elements 14 of the turnstile 10 are arranged below the ceiling device 13. Thus, the entire assembly of the wing elements 14 of the turnstile 10 can be set into rotation together with the ceiling device 13.

[0048] Figure 4 Figure 1 shows, by way of example, the wing elements 14 of the revolving door 10, wherein the ceiling assembly 13 is constructed from several sections 15 that are installed between the wing elements 14. For example, the sections 15 can be glued or screwed to the upper edge of the wing elements 14. Also shown are the translucent sections 17 of the sections 15, which allow light from light sources attached to the underside of the ceiling assembly to pass through the ceiling assembly 13 and into the accessible area of ​​the revolving door.

[0049] Figure 5 Figure 1 shows an example of a wing element 13 arranged on a central column 118 of a revolving door (not shown further), and the display 114 for displaying information 115 is located in the center of the planar wing element 13. For electrical contacting the display 114, the wing element 13 has foil conductors 117, which are led towards the central column 118 and, parallel to or in or on the central column 118, are brought to a rotary feedthrough 119 in order to electrically connect the display 114 to a stationary part of the revolving door.

[0050] The foil conductors 117 are constructed from such a thin layer that they are essentially transparent and therefore invisible, yet they can still conduct electricity. Thus, the foil conductor 117, like the inherently transparent display 114, can also be made invisible, so that the information 115 that can be displayed on the display 114 appears, in a sense, to float centrally above the planar extent of the wing element 13.
