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, on which the turnstile is rotatably mounted. The invention further relates to a method for constructing a revolving door. STATE OF THE ART

[0002] DE 94 03 704 U1 discloses a revolving door in which the ceiling wall is suspended from the building wall by a suspension.

[0003] From EP 1 605 128 B1, an example of a revolving door is known with a turnstile arranged between opposing drum elements, and with a ceiling assembly arranged on the upper side of the drum elements, on which the turnstile is rotatably mounted. The revolving door thus has two opposing drum elements with a turnstile arranged between them, and the ceiling assembly is located above the turnstile and structurally merges into the drum elements.It is shown that the ceiling assembly forms a load-bearing structure with the drum elements, and the ceiling assembly has connecting elements located in the center of the revolving door, with beams extending radially away from it, the revolving door being arranged within the drum walls and below the ceiling assembly, the beams extending from the center to the drum walls being held under prestress to generate an upward force on the connecting elements.

[0004] Unfortunately, this results in a tall ceiling assembly that must be supported by beams or columns located on the outside of the drum elements.

[0005] Another embodiment of a revolving door is known from EP 3 611 326 B1. Here, too, it is evident that the structure of the ceiling assembly is complex and must be assembled on-site as a structural unit with the drum elements. In particular, the drum elements have struts on which the ceiling assembly rests. REVELATION OF THE INVENTION

[0006] The object of the invention is to simplify the construction of a revolving door, in particular by simplifying the connection of the ceiling assembly to the drum walls. This connection should ideally be detachable from the top of the elements, and the rotating mechanism should be rotatably mounted on it. An improved ceiling assembly is intended to significantly simplify on-site assembly of the revolving door and reduce the time required for this process. The ceiling assembly should be as low-profile as possible and integrated into the drum walls. A further object of the invention is to improve the overall appearance and / or functionality of the revolving door.

[0007] This problem is solved starting from a revolving door according to the preamble of claim 1 and a method according to claim 13, each with the characterizing features. Advantageous embodiments of the invention are specified in the dependent claims.

[0008] The invention solves the aforementioned problem by providing that the drum elements each have an inner and an outer glass element, wherein the ceiling assembly rests directly or indirectly on an upper end surface of the respective inner glass element and / or on an upper end surface of the outer glass element. In this context, the glass material can be of various types, in particular plastic glass or the like.

[0009] The drum elements are preferably constructed entirely or at least predominantly from curved glass elements, such that each drum element has an inner glass element and an outer glass element, resulting in an advantageous arrangement for supporting the ceiling assembly. The glass elements can, in particular due to their curvature, possess sufficient stiffness, load-bearing capacity, and strength to support the ceiling assembly, especially with regard to its weight and other external forces. The at least one drum element can have more than two, in particular three or four, glass elements.

[0010] Because the ceiling assembly rests on the upper end face of the inner glass element and / or on an upper end face of the outer glass element, the load of the ceiling assembly can be transferred to the components of the drum elements. If the ceiling assembly rests on the upper end face of the inner glass element, it can be at least partially concealed by the outer glass element. In other words, the end face of the inner glass element or the upper end face of the outer glass element forms the upper edge of the inner glass element or the outer glass element, respectively, which can have a thickness of, for example, 6 mm to 20 mm and preferably 8 mm to 16 mm.

[0011] The ceiling assembly can be placed on the upper end surface directly or indirectly, so that it is also conceivable that an intermediate element, an intermediate layer, an adhesive or a profile element is present between the ceiling assembly and the upper end surface of the inner glass element, so that even then, in accordance with the present invention, the ceiling assembly rests on the upper end surface of the inner glass element without the ceiling assembly and the glass element having to touch or directly abut each other.

[0012] The inner glass element has a shorter vertical length or height, particularly when the revolving door is installed, than the outer glass element. This means that the outer glass element at least partially or completely encloses the ceiling assembly on the outside, especially with regard to its height and / or circumference, preferably when the revolving door is installed. This is particularly true when the ceiling assembly rests on the upper end surface of the inner glass element and / or on an upper end surface of the outer glass element. This can result in an upper offset between the inner and outer glass elements, allowing the ceiling assembly to be recessed between the drum elements. The height specifications refer specifically to the revolving door's installation state.

[0013] Preferably, at least one of the drum elements has an upper offset between the inner and outer glass elements. Preferably, the upper end surface of the outer glass element is higher than the upper end surface of the inner glass element. This allows the ceiling shower assembly to be recessed between the drum elements. The upper offset refers specifically to the installed state of the revolving door. The offset can result, for example, from the glass elements having different heights or being arranged at different heights relative to each other.

[0014] The vertical length of the inner glass element can be, for example, at least 20% to 100%, preferably at least 50% to 100%, and particularly preferably at least 80% to 100%, and especially 60% or 70%, less than the vertical length of the outer glass element of the ceiling assembly's height. In other words, the outer glass element does not have to extend over and cover the entire height of the ceiling assembly on the outside; for example, the ceiling assembly can be covered on the outside only to a partial height by the outer glass element. The lateral covering of the ceiling assembly is also limited to the area of ​​the drum elements, which, in a manner known per se, do not fully enclose the revolving door, but only a portion of it, so that the revolving door has entrance and exit sides for pedestrian access.

[0015] Preferably, at least one of the drum elements has a lateral offset, particularly on both sides, between the inner and outer glass elements. This offset is present, in particular, when the revolving door is installed. A support profile, especially a mullion, can be arranged within this offset. This support profile can be connected to the drum element and / or the ceiling assembly, particularly by a material bond, force bond, and / or positive locking. The support profile can be statically and / or visually integrated into the drum element, thus further improving its appearance and / or structural integrity. The support profile can be dimensioned and / or arranged so that it is flush with the drum element along its circumference and / or radially, either inwards or outwards. This achieves the maximum degree of visual and / or structural integration into the drum element.It is also conceivable that the area of ​​the lateral offset could be coated and / or colored to further improve the appearance.

[0016] Preferably, the inner glass element has a smaller horizontal length or width, particularly when the revolving door is installed, than the outer glass element, or the outer glass element has a smaller horizontal length or width, particularly when the revolving door is installed, than the inner glass element, resulting in a lateral offset on at least one of the drum elements. This does not mean, in particular, that the inner glass element is merely shorter in width because it is positioned inside, so that both glass elements are flush laterally.

[0017] It is also conceivable that the inner and outer glass elements of one drum element have the same horizontal length but are offset from each other. In this way, the inner glass element would protrude on one side of the drum element, and the outer glass element would protrude on the opposite side. This would create a lateral offset, which would vary depending on the side of the drum element.

[0018] The ceiling assembly can be modular and have a sandwich structure, with at least one filler material serving as the core material, and the filler has a cover plate on at least one or both cover surfaces. Therefore, only one top cover plate, only one bottom cover plate, or both top and bottom cover plates can be provided, preferably running parallel to each other with the filler located between them. It is also conceivable that additional cover plates are present, penetrating the filler and forming, for example, an intermediate layer of cover plates.

[0019] An intermediate layer may be necessary, for example, to increase the stiffness of the ceiling assembly, to accommodate components within the assembly, to hold them in relation to one another, or to stiffen them together within their overall structure. However, the basic concept envisions 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 by placing it on top of the drum elements, preferably with a rotatable mounting for the pivot between the drum elements.

[0020] The modular ceiling assembly thus results in a single, manageable component that can be attached to the drum elements and / or the revolving mechanism and, in particular, reversibly detached from them. For example, the ceiling assembly can be pre-assembled at the factory so that, at the destination, it only needs to be connected to the drum elements and the revolving mechanism, without having to assemble its basic components on site. This results in significantly shorter assembly times 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 revolving mechanism, and then removed from its position.

[0021] 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.

[0022] 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.

[0023] 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, heating element, and / or the like, which can be inserted into the openings or into other recesses or intermediate areas in the infill material.

[0024] The inner and outer glass elements can be bonded together to a particular advantage. Specifically, the inner and outer glass elements can together form laminated safety glass (VSG), giving the drum walls exceptional strength and making them shatterproof. For example, it is advantageous for the inner and outer glass elements to be bonded together by means of at least one plastic film. During the production of this laminated glass, the inner glass element can be manufactured with a correspondingly reduced vertical height and bonded to the outer glass element.

[0025] A further advantage is provided by a profile element that rests on the upper end surface of the inner glass element and / or on an upper end surface of the outer glass element, with the ceiling assembly being incorporated in or on the profile element. The profile element is preferably bonded to the inner glass element and / or to the outer glass element, for example, via the upper end surface of the inner glass element and the inner surface of the outer glass element. Alternatively or additionally, the profile element can also be bonded to the ceiling assembly or detachably attached with fasteners.

[0026] The profile element preferably has a first leg and a second leg that is also perpendicular, such that the profile element has, in particular, an L-shape, a T-shape, or a Z-shape, especially wherein the first leg rests on the end surface of the inner glass element and / or wherein the second leg adjoins the inside of the outer glass element. The profile element can, in particular, have the same curvature as the curvature of the glass elements, so that the profile element can be inserted into the inside of the glass elements accordingly. In the Z-shape, one or both parallel legs can run at right angles to the transverse leg.

[0027] At least one section of the outer glass element, which extends higher than the inner glass element, can be advantageously coated, tinted, or made of frosted glass. This ensures that an observer from the outside cannot see the ceiling assembly through the outer glass element, effectively concealing it. It is conceivable that the coating on the inside of the outer glass element may have exposed areas, for example, if sensors are mounted on the inside of the outer glass element, particularly if these sensors are located in or on the ceiling assembly.

[0028] Furthermore, at least one support profile can be provided on the outside of the drum elements, which preferably has a load-bearing connection to the ceiling assembly. For example, it is conceivable that the support profile extends vertically on the outside of the drum elements and has a height that is equal to or slightly higher than the height of the outer glass element. If the ceiling assembly has structural elements, these can be connected to the support profile, which can simultaneously serve as a connection profile for a facade or wall in or on which the revolving door is arranged or installed.

[0029] It is also conceivable that at least one of the drum elements and / or one of the wing elements, in particular an LCD, could have a display for showing information. This would further improve the appearance and / or functionality of the revolving door. In particular, the display could be arranged on, in, or behind the inner glass element.

[0030] 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.

[0031] The object of the invention is further achieved by a method for constructing a revolving door designed according to the features listed above, wherein the method comprises at least the following steps: connecting a shorter inner, in particular curved, glass element with a longer outer, in particular curved, glass element; positioning the drum elements in an opposing arrangement; and preferably: directly or indirectly placing a ceiling assembly onto an upper end surface of the inner glass element and / or onto an upper end surface of the outer glass element. The specifications regarding height refer in particular to the installed state of the revolving door.

[0032] To form the drum elements, the inner glass elements can be bonded to the outer glass elements or connected to each other at least by means of a film, in particular to form laminated safety glass (VSG).

[0033] Furthermore, the ceiling assembly can be bonded to the drum elements, particularly by arranging a profile element on the inner and / or outer glass element. Additionally, a profile element can be installed that rests on the upper end face of the inner glass element, upon which the ceiling assembly is supported. This achieves improved load transfer from the ceiling assembly to the inner and, in some cases, the outer glass element.

[0034] With particular advantage, the ceiling assembly can be detachably glued, screwed or clamped to the drum elements and especially to the profile element after the profile element has been glued to the inner and / or outer glass element and / or to the ceiling assembly.

[0035] It should be explicitly mentioned that features of the method can be transferred to the revolving door according to the invention and vice versa. PREFERRED EXAMPLE OF THE INVENTION

[0036] 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 shows an overall view of the revolving door with a structure according to the invention, Figure 2 shows a flying view of the components of the revolving door, Figure 3 shows a detail view of the transition of the ceiling assembly into a drum element, Figure 4 shows a perspective view of the upper arrangement of the ceiling assembly on the drum elements, Figure 5 shows a further detail view of the arrangement of the ceiling assembly on a drum element, and Figure 6a / b shows two top views of a drum element each.

[0037] Figure 1 Figure 100 shows the revolving door with a turnstile 10, which is rotatably mounted between two drum elements 11. The ceiling assembly 12, which is modular and mounted as a unit on the drum elements 11, is located above the turnstile 10. The turnstile 10 is rotatably mounted on the ceiling assembly 12 at both the floor and underside.

[0038] Figure 2Figure 1 shows a flying view of the components of the revolving door 100 with the drum elements 11, which are designed to receive the ceiling assembly 12 on their upper side. For this purpose, the drum elements 11 have an inner glass element 11a and an outer glass element 11b, wherein the inner glass element 11a has a shorter vertical length than the outer glass element 11b, so that the outer glass element 11b projects beyond the inner glass element 11a and at least partially or completely encloses the ceiling assembly 12 on its outer side, provided that the ceiling assembly 12 rests at least indirectly on the upper end surface 13 of the inner glass element 11a. The view shows that the outer glass element 11b projects beyond the inner glass element 11a by approximately the structural height of the ceiling assembly 12. If the ceiling assembly 12 is arranged on the drum elements 11, the upper edge of the outer glass element 11b is approximately flush with the top of the ceiling assembly 12.

[0039] Figure 3 Figure 1 shows a perspective view of the arrangement of the ceiling assembly 12 on a drum element 11. The ceiling assembly 12 consists of a lower cover plate 16 and an upper cover plate 18, between which a filler material 17 is sandwiched. The drum element 11 has an inner glass element 11a and an outer glass element 11b, and the outer glass element 11b projects beyond the inner glass element 11a in height. The height difference between the upper end surface 13 of the inner glass element 11a and the upper edge of the outer glass element 11b corresponds to a partial height of the ceiling assembly 12, so this embodiment demonstrates that the drum element 11 does not completely, but at least partially, enclose the ceiling assembly 12 on its outer side.

[0040] On the inside of the drum element 11, a profile element 14 is arranged, the vertical leg of which rests against the inner outer glass element 11b and a horizontal leg of which projects radially inwards into the revolving door, so that the ceiling assembly 12 can rest on the horizontal leg. The profile element 14 sits on the end surface 13 of the inner glass element 11a and forms a simple angle profile. The profile element 14 is thus arranged between the ceiling assembly 12 and the drum element 11, and the ceiling assembly 12 is therefore only indirectly attached to the drum element 11, which is a variant included in the invention. The ceiling assembly 12 can also be directly attached, for example, to the underside cover plate 16 or to the filler material.with a structural element present in this or even with an outer protruding edge of the upper cover plate 18 resting on the drum element 11.

[0041] Figure 4 Figure 1 shows in a further view the arrangement of the ceiling assembly 12 on the top of the drum elements 11, wherein the ceiling assembly 12 is shown with a structural component 21 which is connected to a support profile 15 arranged on the outside of the front drum element 11.

[0042] On the underside of the ceiling assembly 12, the revolving door 100 has a ceiling fixture 19, which can be designed to rotate with the turnstile 10 and is positioned approximately parallel to the underside of the ceiling assembly 12. The ceiling fixture 19 includes, for example, lighting elements 20, which can also be transparent flat bodies, and the actual lighting element can be located within the ceiling assembly 12. A motor 23, for example an electronically commutated plate motor, is located centrally in the ceiling assembly 12 and is gearless when connected to the turnstile 10. The rotating part of the motor 23 can cause the ceiling fixture 19 to rotate together with the turnstile 10.

[0043] Finally, it shows Figure 5A further detailed view of the arrangement of the ceiling assembly 12 on a drum element 11, wherein the profile element 14 rests on the upper end surface 13 of the inner glass element 11a and abuts the outer glass element 11b on its inner side. A connecting element 22 is shown on the upper side of the profile element 14, which is connected to a structural component 21 of the ceiling assembly 12. The ceiling assembly 12 in turn comprises the lower cover plate 16, the filler 17, and the upper cover plate 18, wherein the connecting element 22 is designed as a tab-like requirement on the support profile 15 and projects radially inwards into the ceiling assembly 12. This allows for advantageous load transfer from the ceiling assembly 12 into the drum element 11 as well as additionally or exclusively into the support profile 15. The rotating mechanism 10, on which the ceiling device 19 is mounted to rotate, is shown on the underside.

[0044] The Figures 6a and 6bEach figure shows a top view of a drum element. A lateral offset between the inner and outer glass elements 11a, 11b is visible, in which a support profile 25 is arranged. Figure 6b A lateral profile element 24 is arranged between the elements, which simplifies the connection. Subcombinations of the respective possibilities for integrating the support profile 25 onto / into the drum element shown are, of course, possible according to the invention. Such a design visibly and structurally improves the integration of the support profile 25 into the revolving door. The previously described support profile 15 can also be designed according to this example.

[0045] The invention is not limited in its implementation to the preferred embodiment described above. Rather, a number of variants are conceivable which utilize the solution shown even in fundamentally different designs, as long as the variants fall within the scope of the appended claims.
