Description

[0001] The invention relates to a support housing for a turnstile system for personnel access control according to the preamble of claim 1 and to a turnstile system with a support housing according to the preamble of claim 14.

[0002] A turnstile system of the present type therefore comprises a turnstile, a frame consisting of a transverse element and at least two side elements, wherein the transverse element connects the side elements, and the support housing which is attached to the transverse element of the frame or forms the transverse element of the frame.

[0003] The turnstile consists of a vertically arranged, rotatable axis with a number of locking elements attached to it at a circumferential distribution, and at least one upper axis section mounted in a pivot bearing, which may be designed as a pivot pin. The locking elements typically consist of arms or brackets extending radially from the axis, which rotate with the axis and thus define a range of motion for the turnstile that is swept by the locking elements. Usually, three locking elements are arranged at the same height in a star shape around the circumference of the axis, forming an angle of approximately 120 degrees between each other. Alternatively, it is also common to arrange four locking elements in a cross shape at the same height on the axis, forming an angle of approximately 90 degrees between each other. Furthermore, it is common for the aforementioned three or four locking elements to be arranged in a cross shape.Four locking elements form one level of the turnstile, and several levels are arranged one above the other, typically extending over the entire length of the axis. This prevents people wishing to pass through the turnstile from crossing over or under the locking elements without having to rotate the axis and the locking elements attached to it. The locking elements of each level are aligned in axial projection.

[0004] The upper section of the rotating axle sits in a pivot bearing, which in turn is located in the support housing. The support housing, into which the upper section of the turnstile's axle extends, contains not only the pivot bearing but also locking mechanisms that act on the pivot bearing and / or the upper axle section to lock the turnstile in one or both of its directions of rotation as needed. In simple designs, these locking mechanisms may be a latching mechanism that allows rotation of the turnstile in only one direction and always blocks the opposite direction. However, locking mechanisms may also be present that release the lock as needed via a motor, or reverse the direction of rotation of the locking action as needed, completely block or completely release the movement of the axle as needed, and so on.Sometimes a motorized drive for the turnstile is also included in the support housing of a turnstile system of this type.

[0005] Finally, the frame of the turnstile system is designed such that the side elements extend vertically approximately parallel to the axis over essentially its length and are each arranged laterally next to the turnstile's movement area in such a way that they enclose the turnstile between them. One of the side elements has a fixed, single- or multi-part barrier section that extends into the turnstile's movement area, thus making one half of the movement area impassable for people. The barrier section is designed such that the turnstile's barrier elements can move through it in a meshing manner.For this purpose, it is, for example, equipped with corresponding recesses, or, as is usually the case, it consists of multiple arms or bars that project into the spaces between the locking elements of the turnstile on several levels, thus ensuring the interlocking movement of these locking elements through the barrier section. In this way, if the turnstile can only rotate in one direction, passage through the frame is only possible in one direction; the other direction is blocked by the barrier section. The frame can consist of supports or beams, but it can also be formed from housing-like elements, as a portal, as a grid structure, and / or from wall elements, the latter two being, for example, curved to partially surround the turning circle and prevent people from passing through the turnstile without having to rotate it.

[0006] Such turnstile systems with corresponding housings have long been widely used for access control, providing barriers and individual access to companies, parks, zoos, and areas intended for authorized users only. Often, in addition to the turnstile itself, further components such as roofs, lighting elements, traffic lights, signs, laser scanners, or motion detectors need to be attached to the housing. Furthermore, the housing itself must be mounted above the respective entrance on supports, columns, cages, or enclosures.

[0007] Attachments such as signalling elements, input terminals, card readers, recognition modules for biometric characteristics of persons, key switches or communication modules can be provided on the side elements, in particular to allow authorised persons to pass through the turnstile system in the direction that is actually blocked.

[0008] For such add-on parts, holes for attaching brackets and wiring as well as cutouts, if necessary, must be made in the support housing or frame.

[0009] Sometimes, the position of attachments on the housing or frame is crucial, as is the case with motion detectors or people-detection cameras. This specific position is usually not relative to the housing or frame itself, but rather to the passageway. If, for example, the housing needs to be repositioned from a left-hand to a right-hand passage due to site conditions, it may be necessary to remove the position-critical attachments already factory-installed and reattach them in a different position. Obviously, this is not only time-consuming but also negatively impacts the visual appearance of the modified housing.

[0010] The same applies to add-on parts that are provided on the frame, as well as when add-on parts are to be removed because they are no longer required.

[0011] Finally, when subsequently relocating attachments to the carrier housing or frame, but also when additional attachments are to be installed on an already operational turnstile system, it is difficult on site to make the necessary holes for the wiring so precisely that the wiring is concealed by the attachment in a tamper-proof manner.

[0012] The invention is therefore based on the objective of modifying a turnstile system of the type mentioned above and a support housing for such a turnstile system in such a way that the problems with attachments outlined above can be avoided.

[0013] This problem is solved by a carrier housing with the features of claim 1 and by a turnstile system with the features of claim 14. Preferred embodiments of the carrier housing according to the invention are set out in claims 2 to 13; advantageous further developments of the turnstile system according to the invention are set out in claims 15 to 24.

[0014] A support housing according to the present invention, which is provided for a turnstile system for personal access control with the features of the preamble of claim 1 and forms the cross element of its frame or is fastened to this cross element, accommodates the upper axle section of the turnstile's axle as well as the pivot bearing and locking devices which act on the pivot bearing and / or the upper axle section in order to lock the turnstile in one or both of its directions of rotation as required, is further developed according to the invention in that it has at least one mounting groove on an outer side of the support housing, with at least one inner clamping element which can be displaced therein in the manner of a sliding block and with at least one cover for the mounting groove which can be inserted into the mounting groove, in particular pushed in, or placed onto it.

[0015] The turnstile system according to the invention, comprising the features of the preamble of claim 14, i.e., a turnstile consisting of a vertically arranged, rotatable axis with a number of circumferentially distributed locking elements attached thereto, and with at least one upper axis section, in particular an axis journal, seated in a rotary bearing, further comprising a frame of at least two side elements and a transverse element connecting them, wherein the side elements extend vertically approximately parallel to the axis over substantially its length and are each arranged laterally next to a movement area of ​​the turnstile in such a way that they enclose the turnstile between them, and wherein one of the side elements has a fixed, one- or multi-part locking section which projects into the movement area of ​​the turnstile and through which the locking elements of the turnstile can move in a combing manner.further comprising a support housing which is attached to the cross element of the frame or forms the cross element of the frame, wherein the upper axle section of the turnstile's axle extends into the support housing, in which the pivot bearing and locking devices are arranged which act on the pivot bearing and / or the upper axle section in order to lock the turnstile in one or both of its directions of rotation as required, is also modified according to the invention in that the support housing or the frame has at least one mounting groove on each outer side thereof, with at least one inner clamping element which can be displaced therein in the manner of a sliding block, and with at least one cover for the mounting groove which can be inserted into the mounting groove, in particular pushed in, or placed onto it.

[0016] The inner clamping element, which can be moved within the mounting groove, serves to attach components to the carrier housing or frame that are not fixed at a specific mounting point from the factory, but can be mounted on site at various points in the mounting groove, adapted to the conditions, by moving the inner clamping element in the mounting groove.

[0017] Due to the cover of the mounting groove according to the invention, it is not immediately apparent that a mounting groove is present; rather, the cover transforms the mounting groove into a design element whose technical function visually recedes.

[0018] If attachments need to be repositioned on-site on the carrier housing and / or the frame, for example, to adjust the height or lateral position of the attachment to the local conditions, it is particularly advantageous that, within the scope of the present invention, wiring—i.e., electrical power supply lines and signal lines—that run from the interior of the carrier housing to the attachment and therefore require a bore or feedthrough in the carrier housing or frame, do not need to be repositioned as well. This is because the cover of the mounting groove securely conceals the wiring even if it does not exit the wall of the carrier housing directly at the attachment, but runs a short distance within the mounting groove.

[0019] Alternatively, the movable nature of the inner clamping element naturally allows the attachment to be mounted directly above a cable entry in the groove base or moved there, especially if the entry is not exactly where it should be.

[0020] The tamper-proof and visually flawless routing of cabling for attachments within the mounting groove according to the invention, in addition to the flexibility and adjustability of the attachments' position, is a major advantage of the present invention. Further advantages include the fact that, if necessary on-site, an attachment can be repositioned or removed without leaving any visible trace; unsightly covers for unused drill holes and feedthroughs are eliminated.

[0021] The at least one mounting groove can also be provided for fastening the support housing to the frame, which enables a very flexible frame design that can be easily corrected or adjusted on-site later, particularly when the support housing forms the cross element of the frame. For this purpose, for example, two mounting grooves can be provided on the support housing, if necessary also on its end faces, and / or two mounting grooves on the frame, for example on the side elements. The support housing can also be fastened to the cross element of the frame, for example to at least one cross member, using the mounting groove according to the invention.

[0022] The carrier housing according to the invention can be essentially cuboid in shape with four horizontally extending edges; this corresponds to the usual shape of a carrier housing. The mounting grooves according to the invention can then preferably be arranged in the edges – or at least one mounting groove in at least one edge – wherein at least those edges of the carrier housing that are provided with a mounting groove are preferably chamfered and the mounting groove is arranged in the chamfer. This offers advantages for the design of the carrier housing, and the mounting groove is perceived merely as a design element, especially since, according to the invention, it is provided with a cover that expediently covers the entire chamfer width. The mounting groove itself can also cover essentially the entire chamfer width, which enables a particularly stable construction of both the carrier housing and the inner clamping element in the mounting groove.

[0023] The mounting groove according to the invention, which is arranged on the outside of the support housing or on an outer surface of the frame, is preferably provided with two clamping ribs which, viewed in cross-section, extend laterally into the mounting groove on both sides, thereby forming an inner clamping surface and preferably also an outer clamping surface. In this way, an inner clamping element and an outer clamping element can clamp the clamping ribs between them and thereby form a force-fit connection with the mounting groove when an outer clamping element, for example as part of an attachment or a holder for such, is placed onto the mounting groove from the outside and connected to the inner clamping element, for example by means of a screw connection.

[0024] The clamping ribs, in conjunction with a groove base of the mounting groove, can form a groove cavity for receiving the inner clamping element, preferably in such a way that the inner clamping element fills the cross-section of the groove cavity as completely as possible in order to ensure the most stable possible fastening of attachments.

[0025] It is particularly preferred if the clamping ribs, on their side opposite the groove cavity, form part of a guide groove for inserting or inserting the cover according to the invention. This makes it possible, for example, to clamp the cover between the inner clamping element and an outer clamping element and thus fix it in a tamper-proof manner.

[0026] The inner clamping element can be provided with at least one threaded pin to press against the bottom of the mounting groove and thus additionally fix the inner clamping element in the mounting groove.

[0027] As already mentioned, the present invention provides that the inner clamping element, which sits in the mounting groove, can be connected to an outer clamping element of an attachment in order to fix the two clamping elements to the mounting groove and preferably also to clamp the cover between the inner and outer clamping elements. Clamping the cover can also function without the inner and outer clamping elements forming a clamping connection for fixing it in the mounting groove.

[0028] As a further preferred embodiment of the present invention, it can be provided that light sources are arranged in the mounting groove, advantageously combined with the fact that the cover consists of a transparent and / or translucent material and / or a material made translucent by means of bores and cutouts. This makes it possible to design the mounting groove according to the invention even more clearly as a design element or to use it for signaling purposes. The mounting groove offers a very simple way to attach signaling via light signals to the carrier housing and / or the frame; such a mounting groove is ideally suited for accommodating light sources and concealing their wiring invisibly and tamper-proof.

[0029] As already mentioned at the beginning, attachments such as roof elements, lighting elements, signaling elements, signs, laser scanners, cameras, motion detectors, and radio modules can be attached to the support housing using the mounting groove according to the invention. Lighting elements, signaling elements, signs, laser scanners, cameras, motion detectors, input terminals, card readers, recognition modules for biometric features, key switches, communication modules, and much more can be attached to the frame of the turnstile system according to the invention using the mounting groove according to the invention. These attachments are expediently provided with integrated or permanently mounted outer clamping elements to enable them to be easily attached to the inner clamping elements in the mounting groove according to the invention.

[0030] The mounting groove according to the invention can, in particular, be provided with feedthroughs in its base, for example, feedthroughs prepared in a grid for electrical and electronic power supply and signal lines. As already explained, due to the cover of the mounting groove according to the invention, it is not critical if such power supply and signal lines have to bridge a certain distance within the mounting groove between the feedthrough in the support housing and the attachment.

[0031] An exemplary embodiment of a turnstile system according to the invention and a support housing designed according to the invention are described and explained in more detail below with reference to the attached schematic drawings. This is merely an example and is not intended to limit the invention; nevertheless, the drawings and the following description may contain features essential to the invention.

[0032] They show: Fig. 1: a schematic isometric view of a turnstile system from above; Fig. 2: the turnstile system made of Fig. 1 in side view, Fig. 3: the upper section of the Fig. 2 in magnification; Fig. 4: a corner of a support housing of the turnstile system from the Fig. 1 to 3 in detail, in sectional view.

[0033] Fig. Figure 1 shows an embodiment of a turnstile system according to the invention in a schematic, oblique view from above. A frame 1 consists of a first side element 2 and a second side element 3, which also carries a boundary grille 4, as well as a transverse element that connects the first side element 2 and the second side element 3 at the top and is designed here as a support housing 12. The two side elements 2, 3 of the frame 1 consist essentially of beams that were manufactured by forming or joining metal profiles.

[0034] The two side elements 2, 3 of the frame 1 enclose between them a movement area 5 of a turnstile 6, which in turn consists of a vertically arranged, rotatable axis 7 with a number of locking elements 8 attached to it at a distributed location around the circumference. The locking elements 8 are formed by brackets that are attached to the rotatable axis 7 and rotate with it, so that the movement area 5 of the turnstile 6 is defined by the locking elements, viewed in vertical projection, sweeping over it as they move with the rotating axis 7.

[0035] The locking elements 8 are arranged in a total of eight levels 9, 9', 9''. Each level comprises three locking elements 8, which are equidistantly distributed around the circumference of the axis 7, so that they each enclose an angle of approximately 120 degrees between them. In vertical or axial projection, the locking elements 8 of the individual levels 9, 9', 9''... are arranged in alignment, as shown in Fig. 1 can be seen.

[0036] The turnstile 6, more precisely its axis 7, is mounted in the support housing 12 and is held accordingly by it. The locking devices necessary for a turnstile system, for locking and releasing a rotational movement of the turnstile 6, are also located there (not visible here).

[0037] To ensure that the turnstile system allows people to pass through in only one direction as needed, a fixed barrier section 10 (shown here only schematically) with a total of seven barrier bars 11 is provided on the first side element 2 of the frame 1, as is known per se. The barrier bars 11 are arranged at a height such that they project into the spaces between the individual levels 9, 9', 9'' of the barrier elements 8 of the turnstile 6, whereby the barrier elements 8 then move in a meshing motion through the barrier bars 11 and thus through the barrier section 10 when the turnstile 6 rotates. The barrier section 10 therefore prevents passage through the turnstile system in the direction shown. Fig. 1 half shown on the right, without obstructing the rotation of the turnstile 6.

[0038] The present embodiment allows for a free passage in the representation of the Fig. 1. From right to left, the turnstile 6 can only move freely clockwise when viewed from above. Turnstile 6 is locked in a counter-clockwise direction, so access from left to right is restricted. Fig. 1 is only possible in exceptional cases. Such an exceptional case exists when a person authorized to pass proves their authorization to pass at an input terminal 13 on the second side element 3 of the frame 1, for example by entering a numerical code, placing a finger on it, or the like.

[0039] In Fig. 2, which the turnstile system made of Fig. Figure 1, in a side view showing the side of the free passage, shows the same components as in Fig. 1 provided with identical reference numerals, so that in this respect reference is made to the preceding description of the Fig. 1. Reference can be made to this. The same applies to the Fig. 3, which only cover the upper part of the Fig. Figure 2 shows an enlarged view and visualizes further details, as described below.

[0040] The carrier housing 12 is essentially cuboid in shape, with two horizontal side surfaces 21 and two vertical side surfaces 22. On the in Fig. On the vertical side surface 22 visible in Figure 2, a mounting groove 14 designed according to the invention can be seen, which carries an optical signaling element 15. This displays a luminous indication, if necessary, to signal, for example, that the turnstile system is freely passable, specifically on the left half, or the opposite, for example, when the turnstile is completely locked or released in the opposite direction.

[0041] The mounting groove 14 is arranged in a horizontally extending, chamfered edge 23, covering the entire width of the chamfer. To the right and left of the signaling element 15, the mounting groove 14 is provided with a cover 16, so that, for example, power supply cables and / or signal cables for the signaling element 15 can be routed invisibly and tamper-proof within the mounting groove 14.

[0042] Fig. 3 shows the upper section of the Fig. 2 in an enlarged view, where again identical components are provided with identical reference numerals.

[0043] The internal structure of the support housing 12 is schematically indicated by broken lines: An upper axle section 17 of the axle 7 sits in a pivot bearing 18, which is attached to the underside of the support housing 12. A locking device 19 engages the upper axle section 17 of the axle 7 and consists, for example, of a latch mechanism that ensures that the upper axle section 17 can only rotate clockwise when viewed from above; counterclockwise movement is prevented by the latch mechanism. To allow persons authorized to pass through the turnstile in the opposite direction, a release device 20 is provided for the latch mechanism, which disengages the locking device 19 from the upper axle section 17 and thus releases the axle 7 from rotation.Of course, many other variants are conceivable, including a motorized movement of the axis 7 by means of corresponding devices provided inside the support housing 12, in particular a geared motor.

[0044] Fig. Figure 4 shows a chamfered edge 23 of the carrier housing 12 with a mounting groove 14 arranged in the chamfer. In the present embodiment, the mounting groove 14 has a groove base 24 and two clamping ribs 25, which together with the groove base 24 form a groove cavity 26. This groove cavity 26 serves to receive an inner clamping element 27, which can be moved along the mounting groove 14. The clamping ribs 25 extend laterally into the mounting groove 14 in cross-section and thereby form an inner clamping surface 28 and an outer clamping surface 29, respectively.

[0045] The signaling element 15 is simultaneously designed as an outer clamping element 30, which is connected to the inner clamping element 28 via a threaded pin 31 (only indicated). This threaded pin 31 pulls the inner clamping element 27 against the inner clamping surfaces 28 of the clamping webs 25. The opposing force pulls the outer clamping element 30 against the cover 16, which in turn bears against the outer clamping surfaces 29 of the clamping webs 25. This cover 16 is inserted into a guide groove 32 (in the direction of the normal to the plane of the drawing), with the outer clamping surfaces 29 forming the groove wall.

[0046] The groove 24 contains penetrations 33 for power supply and / or signal cables.

[0047] Due to the connection of the inner clamping element 27 to the outer clamping element 30 by means of the threaded pin 31 and the resulting clamping forces on the clamping lugs 25, a firm, force-fit connection is created, by means of which the signaling element 15 is securely attached to the carrier housing 12 and the cover 16 is simultaneously held immovably in place. This attachment can be made in any desired position along the mounting groove 14. Subsequent adjustment of the mounting position is also possible at any time. Various attachments, not just signaling elements, can be mounted on the mounting groove 14 in a similar manner. List of reference symbols: 1 frame 2. Page element (first) 3.
