CAROUSEL DOOR

Description

[0001] The invention relates to a revolving door with a turnstile arranged between opposing drum elements and with a ceiling assembly which is connected to the drum elements on its upper side, in particular indirectly or directly, and on which the turnstile is rotatably mounted, wherein the turnstile has wing elements, wherein at least one of the wing elements has a display for showing information.

[0002] Revolving doors with a rotating mechanism arranged between opposing drum elements are known from DE 101 22 526 B, DE 10 2004 029 762 A1, and WO 94 / 00661 A1. These revolving doors are designed with a ceiling assembly connected to the drum elements at the top, on which the rotating mechanism is rotatably mounted. The rotating mechanism is constructed from wing elements, each of which has at least one brush arrangement. Such brush arrangements can be positioned on the wing elements facing the ceiling assembly, the floor, or the inner surfaces of the drum elements. In particular, these brush arrangements wipe the inner surface of the drum elements during rotation of the rotating mechanism. Wing elements are known with frames containing glass panes, and the brush arrangements are provided on the outside of the frame.Furthermore, wing elements are known as all-glass wings, and brushes can also be arranged along the edges of these all-glass wings using appropriate profile strips. In this case, a profile structure is also used to connect the brush assembly to the all-glass wing, which, disadvantageously, necessitates additional joints and edges on the wing elements, and the profile structure is generally wider than the glass elements. This wider and therefore thicker profile structure also results in additional edges and steps, further increasing the risk of injury for people using the revolving door.

[0003] CN108678620A reveals a revolving door with a turnstile and a ceiling assembly.

[0004] The object of the invention is to improve the appearance and / or functionality of the revolving door as a whole.

[0005] This problem is solved starting from a revolving door according to the preamble of claim 1 with the characterizing features. Advantageous embodiments of the invention are specified in the dependent claims.

[0006] The invention includes the technical teaching that electrical foil conductors are arranged on the wing elements, by means of which the display, in particular the LCD, is electrically contacted. This allows for further improvement of the appearance and / or functionality of the revolving door. Furthermore, it improves the integration of the display into the wing element.

[0007] It is also conceivable that at least one of the wing elements incorporates a sensor and / or a lighting element. These can also be electrically and / or data-transmitting connected via electrical foil conductors arranged on the wing element. These electrical foil conductors can also be arranged in a brush configuration on a wing edge of the at least one wing element or on a central column of the rotary joint and are preferably connected via a rotary feedthrough. This provides additional functionality on the wings without visible connections.

[0008] It is conceivable to display a risk of entrapment, injury, or imprisonment threatening the user, and preferably also to display actions to minimize this risk.

[0009] According to the invention, the electrical foil conductors are arranged in a brush assembly 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.

[0010] Preferably, the sash elements are designed as all-glass sashes. As already described, such all-glass sashes are designed without a sash frame or frameless.

[0011] It is also conceivable that at least one of the drum elements has a display, in particular an LCD, for showing information. This would further improve the appearance and / or functionality of the revolving door. This display could also be electrically and / or data-transmitting connected via electrical foil conductors arranged on the drum element. It is also conceivable that at least one of the drum elements has a sensor and / or a lighting element. These could also be electrically and / or data-transmitting connected via electrical foil conductors arranged on the drum element.

[0012] It is also conceivable that at least one brush arrangement is formed on each of the wing elements. Preferably, the brush arrangement has a width adapted to the width of the wing elements. A smooth transition from the wing element into the brush arrangement, and preferably extending into the bristles, is advantageous, so that the width of the brush arrangement corresponds to the thickness of the wing element. In particular, this results in an improvement of brush arrangements on the wing elements of revolving doors. Specifically, the brush arrangement can be further developed so that it transitions into the wing elements with as few joints and edges as possible.

[0013] The brush arrangement can comprise a brush with a multitude of bristles; however, for the purposes of the invention, the term "brush arrangement" also includes brushes made of a single rubber body, foam rubber, felt strips, a silicone lip, or the like, so that the brush arrangement need not be a brush in the classical sense. The brush arrangement can therefore be constructed from alternative materials and designs.

[0014] The wing elements can be formed from at least one or two glass plates, and it is also conceivable that more than two glass plates, particularly with appropriate intermediate layers, are used to form the wing elements. In particular, the wing elements can be made of so-called laminated safety glass (VSG), which comprises several glass plates with at least one intervening plastic layer or film.

[0015] According to one possible embodiment, the brush arrangement comprises a mounting strip and a brush strip arranged on the mounting strip. The mounting strip and / or the brush strip can each have a profile cross-section with a width that corresponds approximately to, or exactly to, the width of the respective wing elements. The width corresponding approximately to the width of the wing elements includes deviations of less than 10%, less than 5%, less than 2%, and, in particular, less than 1%. Thus, the bristles of the brush arrangement can also fan out and project from the plane of the wing elements, and the wing elements still constitute a variant embodiment of the invention.

[0016] Furthermore, the brush strip can have a base section with a width corresponding to the width of the respective wing elements. In particular, the corresponding width can vary by up to 5%, more specifically 3% or 1%, or 5 mm or 2 mm. The brush strip is preferably embedded in the mounting strip with the base section and can have bristles made of natural hair, synthetic hair, silicone, foam rubber, one or more lips, or the like, which, without force being applied and / or in their new state, have the same width as the wing elements. When force is applied, i.e., when the brush strip slides along the inside of the drum elements, the bristles of the brush strip can have an angle of inclination that is particularly less than 30°, more particularly 20°, more particularly 10°, and preferably less than 8°.Consequently, in accordance with the invention, the brush arrangement can also diverge from the plane of the wing elements; however, when unloaded or in its new state, the bristles of the brush strip extend in the plane of the wing elements.

[0017] The wing elements have a wing edge, on which a mounting strip is arranged for the attachment of the brush assembly, particularly for detachable fastening. The mounting strip can be connected to the wing edge by a material bond, especially by adhesive bonding, and / or by a force-fit and / or a form-fit connection. This avoids the need for a profile that laterally covers and frames the glass elements. The brush assembly can be attached to the mounting strip by a material bond, force-fit connection, and / or a form-fit connection. For example, the brush assembly can be glued, clamped, or positively engaged with the mounting strip, for instance, using a keyhole geometry or similar design into which mushroom-headed pins are snapped.

[0018] Advantageously, a cavity is formed between the wing edge and the mounting strip and / or the receiving strip, in which electrical conductors can be arranged. Thus, even all-glass wing elements with the monolithic brush arrangement according to the invention can be equipped with sensors and / or lighting elements that can be connected via electrical conductors not visible from the outside through the brush arrangement.

[0019] The respective wing edge to which the brush assembly is attached can face the inside of the drum elements, or the wing edge can face the bottom or the ceiling assembly. Naturally, multiple brush assemblies on one or more wing edges of at least one wing element are conceivable. This allows the wing element to have a monolithic appearance on all sides.

[0020] Regarding the ceiling assembly, its dimensions are such that the drum elements form the outer edge of the revolving door and / or the ceiling assembly, or any part of it, does not extend beyond the drum elements. This further design of the drum elements, particularly concerning the transition to the ceiling assembly, offers the advantage that the revolving door has side wall sections that are seamless and uninterrupted, thus providing a monolithic appearance and minimizing dirt accumulation, as no dirt can collect in transitions, crevices, joints, radial offsets, or other transitions. This monolithic design continues in the wing elements and the brush assemblies attached to them.

[0021] It is specifically designed that the ceiling assembly is at least partially recessed between the drum elements in such a way that the drum elements, in an upper area, frame the ceiling assembly externally and / or form an upper edge on the revolving door. In this respect, a section at the structural height of the ceiling assembly can also form part of the side wall area, which, viewed from an upper edge, transitions seamlessly downwards into the drum elements. The edge forms the upper circumferential border of the revolving door and can be formed by the ceiling element, by the ceiling element at the transition to the drum element, or solely by the drum element.

[0022] This also makes it possible for the upper cover plate of the ceiling assembly to radially extend beyond or cover the drum elements in the area of ​​the upper end edge of the revolving door, so that it reaches up to the vertical outer surface of the drum elements.

[0023] The drum elements extend, in particular, over a vertically and circumferentially externally spanned side wall area up to the upper end edge of the revolving door without interruption and continuously, if the ceiling assembly is enclosed on the inside in the drum elements.

[0024] A particular advantage of the ceiling assembly is its sandwich construction, comprising a bottom cover plate, a filler, and / or a top cover plate. The top cover plate, together with the drum elements, can form the upper edge of the revolving door. This allows for a modular design, providing at least one filler as the core material, with the filler having 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.

[0025] 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.

[0026] According to an additional and particularly preferred alternative variant, the bottom cover plate and / or the top cover plate can be bonded together with the filler using a thermal bonding process. This allows the ceiling assembly, after it has been assembled with the filler and the cover plates, and optionally with other functional and structural elements, to be thermally pressed, or essentially baked, in an oven by applying pressure and heating to create a bonded structure. This process also allows for the simultaneous calibration of the parallelism of the cover plates and the precise height of the ceiling assembly.

[0027] To further improve the monolithic appearance of the revolving door, especially in conjunction with the monolithic-looking wing elements and the brush arrangements that seamlessly transition to them, a ceiling-mounted device can be arranged to rotate with the revolving mechanism, to which the brush arrangements of the wing elements are attached at rest on the upper side.

[0028] 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 constitutes 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.

[0029] In particular, the ceiling device can completely cover the underside of the ceiling assembly, wherein the ceiling device preferably has a diameter that is substantially the same as 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%. In particular, the ceiling device can have a diameter such that it substantially completely covers the underside of the ceiling assembly, so that the underside of the ceiling assembly is no longer visible. In any case, the diameter of the ceiling device can be determined such that the ceiling assembly remains visible only from a side perspective.

[0030] The turnstile can have multiple wing elements, for example, two, three, or four wing elements, with the ceiling mounting comprising sections arranged between the wing elements at the upper end of the turnstile, facing the ceiling mounting. It is also possible to arrange these sections on top of the wing elements, or the ceiling mounting 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 mounting to be designed in two parts, specifically comprising two semicircles.

[0031] 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.

[0032] 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.

[0033] It is also conceivable that the display is positioned on the glass plate in such a way that it is enclosed by the transparent glass surface of the plate. This would improve the integration of the display into the wing element.

[0034] 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.

[0035] 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.

[0036] It is also conceivable that the drum elements each have an inner glass element and an outer glass element, with the ceiling assembly resting directly or indirectly on an upper end surface of the inner glass element and / or on an upper end surface of the outer glass element. It is conceivable that the inner glass element has a shorter vertical length than the outer glass element, so that the outer glass element at least partially or completely encloses the ceiling assembly on the outside. In combination with the wing elements, this further improves the appearance of the revolving door. Users are given the impression of a seamless system while simultaneously experiencing a high degree of interaction.

[0037] Preferably, at least one profile element is provided that rests on the upper end surface of the inner glass element and / or the upper end surface of the outer glass element, with the ceiling assembly being incorporated in or on the profile element. The profile element can be bonded to the inner glass element and / or to the outer glass element. Preferably, at least a portion of the outer glass element that extends higher than the inner glass element has a coating or is colored. This further improves the appearance and functionality of the overall system. 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 is a perspective view of the essential components of the revolving door and with wing elements to which brush assemblies are attached; Figure 2 is a view of a wing element with a display attached to it; Figures 3a / b / c are an embodiment for arranging a display on a wing element; Figure 4 is an exploded view of a brush assembly spaced apart from a wing element; Figure 5 is a further detail view of the brush assembly on the wing element; and Figure 6 is a sectional view through the ceiling assembly with a wing element arranged below it, showing a brush assembly.

[0039] Figure 1Figure 1 shows a flying view of the components of the revolving door 100 with two opposing drum elements 11, designed to receive the ceiling assembly 12 from above. For this purpose, the curved drum elements 11 have an inner glass element 11a and an outer glass element 11b, the inner glass element 11a having 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 the outside. Brush assemblies 14 are attached to the wing edges 20 of the wing elements 13 of the revolving door 10, pointing towards the inner surface of the drum elements 11. Additional brush assemblies 14 may also be arranged on the wing edges 20 of the wing elements 13, pointing towards the ceiling assembly 12, either on the floor side or towards the ceiling assembly 12, though not shown in detail.

[0040] The wing elements 13 are designed as all-glass wings. Furthermore, one of the drum elements 11 has a display (not shown). The display is electrically and data-transmittingly connected via foil conductors (also not shown). The revolving door is thus transparent and interactive. Additionally, one of the drum elements 11 can have lighting (not shown) and / or a sensor (not shown), which are also connected via foil conductors.

[0041] Figure 2Figure 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.

[0042] 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.

[0043] The display can show (not shown) a risk of entrapment, injury or imprisonment for the user, and can also show actions to minimize the risk.

[0044] Furthermore, the wing element 13 includes a sensor (not shown) and / or a lighting element. These can also be electrically and / or data-transmitting via electrical foil conductors 117 arranged on the wing element or via other foil conductors (not shown). These electrical foil conductors can also be arranged on the central column 118 of the turnstile and connected to the rotary feedthrough 119. This provides additional functionality on the wings without visible connections.

[0045] Figure 3a Figure 1 shows a cross-section through a wing element 13 having a glass plate 116, and the display 114 is applied to a surface of the glass plate 116, so that the glass plate 116, which forms the wing element 13, also forms the support substrate for the display 114.

[0046] Figure 3bThe wing element 13 includes a glass plate 116 with a display 114, wherein the display 114 is covered with a protective body 120, for example, a protective film. The display 114 can form the actual electrically active LCD surface body, which is applied to the glass plate 116 as a substrate, and the film-like protective body 120 covers the display 114, in particular also the rest of the wing element 13.

[0047] Figure 3cFigure 13 shows the wing element 13 with a first glass plate 116 and a second glass plate 116 arranged parallel to it, with a laminated film 121 inserted between the two glass plates 116. The display 114 is located between the laminated film 121 and the lower glass plate 116, so that it is protected between the two glass plates 116. In this way, the wing element 13 can be constructed as laminated safety glass, and the display 114 is protected between the two glass plates 116.

[0048] Figure 4 Figure 1 shows a perspective view of the brush assembly 14 spaced apart from the wing element 13, creating a flying view. The brush assembly 14 has a mounting strip 16 and a brush strip 17, and the bristles 19 are either arranged on the brush strip 17, for example pressed in, or formed integrally with the brush strip 17.

[0049] The sash element 13 comprises two glass plates 15, which are bonded together, for example, by a film (not shown in detail), so that laminated safety glass is used to form the sash element 13. However, in an embodiment not shown, the sash element 13 can be formed from a single glass plate 15, in particular tempered safety glass (ESG). The other features are applicable analogously in this case. The sash element 13 has a width B and a mounting strip 21 on the sash edge 20, which is, for example, glued to the sash edge 20. In the example shown, the mounting strip 21 is U-shaped and glued to the sash edge 20 with its outer base, so that a cavity 22 is created inside the U-shape when the receiving strip 16 of the brush assembly 14, which is formed with an H-profile, is attached to the mounting strip 21, for example, by clipping it on.For example, electrical conductors 23 can be guided in the cavity 22 along the wing edge 20 of the wing element 13, for which cable holders can also be provided in the cavity 22, for example arranged on the mounting strip.

[0050] The H-profile of the receiving strip 16 provides a cross-section by means of which the brush strip 17 can be inserted on a first side of the receiving strip 16, and on an opposite side the receiving strip 16 together with the mounting strip 21 forms the cavity 22 when the receiving strip 16 is, for example, clipped, clamped or attached to the mounting strip 21 with a fabric closure.

[0051] Both the mounting strip 16 and the brush strip 17, particularly with the bristles 19, correspond to the width B of the wing element 13, so that in the assembled state of the brush assembly 14, the wing elements 13 do not thicken at their edges, and the entire brush assembly 14 corresponds approximately to the width of the wing elements 13. The deviation of the width of the brush assembly 14 relative to the width of the wing elements 13 can be, for example, up to a maximum of 30%, preferably up to a maximum of 20%, particularly preferably up to a maximum of 15%, and most preferably up to a maximum of 10%, by which the width of the brush assembly 14 exceeds the width B of the wing elements 13. In the new state and without the bristles 19 of the brush assembly 14 being pressed against the inside of the drum elements 11, the deviation can also be significantly less than 10%, ideally at 0%.

[0052] Figure 5Figure 1 shows the wing element 13, which is constructed from two interconnected glass plates 15, with the brush assembly 14 located at the wing edge 20. The mounting strip 16 creates the cavity 22, through which, for example, the electrical conductor 23 can be passed. On the outside of the mounting strip 16, the brush strip 17 is enclosed by a base section 18, and the bristles 19 extend from the base section 18 away from the wing element 13.

[0053] The bristles 19 can diverge at a slight angle α, for example less than 20%, preferably less than 10%, preferably less than 5% and most preferably less than 2%, so that, in particular when the bristles 19 are in contact with the inside of the drum elements, a slight deviation of the bristles 19 from the width B of the wing element 13 can occur.

[0054] Figure 6 Another view shows the wing element 13 below the ceiling assembly 12, and the brush assembly 14 with the mounting strip 16 and the brush strip 17 is arranged on the wing edge 20 of the wing element 13. The brush strip 17 is in contact with the inside of the drum element 11 of the revolving door 100. A ceiling element 24 is arranged on the ceiling side, and the illustration clarifies that the brush assembly 14 extends up to the ceiling element 24. The ceiling element 24 rotates with the rotation of the wing elements 13, so that the brush assembly 14 and the ceiling element 24 form a clear geometric boundary, designed with a minimal number of edges and steps.

[0055] The invention is not limited in its implementation to the preferred embodiment described above. Rather, a number of variants are conceivable, which utilize the presented solution even in fundamentally different designs. The scope of the present invention is defined by the appended claims.
