Description

WO 2013/010196 PCT/AT2012/000189 Holding device for a roulette wheel The invention relates to a roulette arrangement as claimed in claim 1 and to a roulette table as claimed 5 in claim 16. Holding devices according to the invention are preferably used in the field of gambling, in particular in casinos. 10 One substantial problem in the case of previously known roulette arrangements consists in that a manipulation of arrangements of this type is very easily possible. A known system is described in EP2065079B1. Said system 15 is extremely complicated and comprises a wheel holding table which is held horizontally by means of a relatively complicated construction. Moreover, said system is susceptible to manipulation. For instance during the cleaning of the casino, an object can 20 readily be pushed under the roulette wheel, in order to manipulate the course of the game. It is thus readily possible, for instance, to clamp coins or casino tokens between the table and the 25 roulette wheel and therefore to influence the location of the running face, in particular to make it oblique. In addition, influencing of the running face can be detected only with great difficulty. 30 It is therefore an object of the invention to provide a roulette arrangement which is simple and secure against manipulation. Furthermore, it is an object of the invention to retrofit existing roulette tables in a manner which is secure against manipulation. 35 The invention achieves this object by way of the features of the characterizing part of independent patent claim 1. The invention relates to a roulette arrangement comprising a roulette wheel and a holding WO 2013/010196 - 2 - PCT/AT2012/000189 device for the roulette wheel, which holding device has a frame with a number of at least three supports, the holding device having a number of holding elements which project from the frame for the rigid and 5 stationary connection of the roulette wheel to the frame, it being possible for the length of the holding elements which projects from the frame to be adjusted in each case, the roulette wheel having receiving recesses for the holding elements, which receiving 10 recesses are adapted to the shape, size and arrangement, the holding elements being introduced into the respective receiving recesses and connecting the holding device in a rigid and stationary manner to the roulette wheel. It is provided according to the 15 invention that the receiving recesses of the roulette wheel are of piercing configuration, the holding elements, in particular their threaded rods, being introduced from the underside of the roulette wheel through said roulette wheel into the receiving 20 recesses, that a closure element is inserted from the upper side of the roulette wheel into the receiving recess, and - that the holding elements, in particular their threaded parts, have a thickened point, and that the 25 roulette wheel is clamped between the thickened point, in particular of the threaded part, and the closure element, in particular its head part, and is therefore connected in a rigid and stationary manner to the frame. 30 On account of the rigid connection which is then possible of the holding device to the roulette wheel, subsequent adjustment of the position of the roulette wheel, in particular of its running face, is to this 35 extent only possible at all with difficulty. As a result of the holding elements which can be adjusted independently of one another, there is the possibility that the inclination of the roulette wheel can be set WO 2013/010196 - 3 - PCT/AT2012/000189 freely and, in particular, a horizontal orientation of the roulette wheel is possible. In this case, the rotational axis of the roulette wheel runs exactly vertically or perpendicularly. In addition, a roulette 5 arrangement of this type has the advantage of increased stability and a lower susceptibility to manipulation in comparison with known roulette arrangements. One mechanically particularly simple refinement of a 10 holding device provides that the supports of the frame are connected to one another via a linkage. A further advantageous embodiment which simplifies the construction of the frame provides that the supports 15 are arranged parallel to one another. As an alternative or in addition, one particularly stable refinement of the invention provides that the supports are arranged at the same spacing from a 20 central axis. Here, in addition or as an alternative, it can be provided for the further stabilization of the holding device that the supports are at the same spacing from 25 the respectively next supports. One embodiment of the invention which is particularly stable, easy to manufacture, and the frame of which manages with a low number of different parts, provides 30 that the linkage comprises the following elements which are connected in a stationary and rigid manner to one another: - a number of central linkage parts which are situated at different positions of the central axis, 35 and - a number of connecting elements which connect in each case one of the central linkage parts and one of the supports to one another.

WO 2013/010196 - 4 - PCT/AT2012/000189 Particularly high stability can be achieved here by in each case one connecting element which connects the respective support to the respective central linkage 5 part being provided in order to connect each individual support to each individual central linkage part. One embodiment of the invention which is particularly stable and at the same time light provides that the 10 supports are formed by tubular pieces which, in particular, run in a straight line and are, in particular, oriented vertically. In order to improve the steadfastness and stability, it 15 can be provided that, at their lower end and/or end which is remote from the holding elements, the supports in each case have a fastening element for fastening to the floor. In addition, a change in the location of the running face is suppressed as far as possible by way of 20 fastening to the floor. For the advantageous stable fastening of the roulette wheel to the holding device, it can be provided that each holding element projects from in each case one of 25 the supports, and/or that in each case one holding element projects from each of the supports. A particularly simple embodiment of the invention results if the respective holding element is formed or 30 arranged at the upper end of the respective support and/or at that end of the respective support which is remote from the fastening element. A particularly advantageous and stable connection 35 results if the holding elements are of straight configuration and/or are oriented in the same direction as the respective support, from which they project.

WO 2013/010196 - 5 - PCT/AT2012/000189 Furthermore, a particularly advantageous and stable connection results if, as an alternative or in addition, each of the holding elements is formed by a bolt which projects from the respective support. 5 In order to determine manipulations subsequently in a simple manner, it can be provided that the central linkage parts, the connecting elements and the supports are connected to one another, in particular by sealing 10 screws, and at least one of the connections which are produced in this way is sealed by means of in each case one seal element, with the result that, after setting up, a change in the position, location, length and/or orientation of the linkage parts and/or connecting 15 elements and/or supports brings about the fracture or cracking of a seal element, and can therefore be determined subsequently. In order to achieve a particularly simple and easily 20 adjustable construction, it can be provided that the holding element has a threaded rod which is screwed into a securing nut which is fastened to the respective support or into a bolt which is screwed into the securing nut. 25 In order to increase the stability, it can be provided that the fastening elements of the holding device are connected in a rigid and stationary manner to the floor. 30 In order to determine manipulations subsequently in a simple manner, it can be provided that the holding elements and the roulette wheel are connected to one another, in particular, by sealing screws and the 35 connection which is produced in this way is sealed by means of a seal element, a change in the position, location, length and/or orientation of the linkage parts and/or connecting elements and/or supports after WO 2013/010196 - 6 - PCT/AT2012/000189 setting up bringing about the fracture or cracking of a seal element, and it therefore being possible to determine it subsequently. 5 A further preferred aspect of the invention relates to a roulette table comprising a seating table for players participating in the game having a table top, and a roulette arrangement of the type which is mentioned in the preceding text. It is provided here that the table 10 top has recesses which are penetrated by the supports and/or the holding elements, and that the roulette wheel is arranged on the holding elements at a level above the surface of the table top. 15 In order to avoid the transmission of mechanical influences to the table, it can be provided that the roulette wheel is arranged in a contactless manner spaced apart from the table top, in particular at a spacing from 0.5 mm to 3 mm. 20 As an alternative or in addition, it can be provided for the same purpose that the roulette wheel and the roulette table are not connected to one another or are arranged without contact, and/or that there is a 25 spacing between the roulette wheel and the roulette table. Preferred exemplary embodiments of the invention are shown in detail using the following drawings, without 30 restricting the general concept of the invention. Fig. 1 shows a first preferred embodiment of a holding device according to the invention. Fig. 2 shows the embodiment which is shown in fig. 1, in section along a 35 horizontally running sectional B-B. Fig. 3 shows the embodiment of the invention which is shown in figs. 1 and 2, in section along the vertically running sectional plane A-A. Fig. 4 shows one preferred WO 2013/010196 - 7 - PCT/AT2012/000189 embodiment of the invention, namely a roulette table, in an oblique view. Fig. 5 shows a section through the roulette table (shown in fig. 4) along a vertical sectional plane. Fig. 6 shows one detail of figs. 1 and 5 5, the connection between the holding device and the roulette wheel being shown in detail. Fig. 6 shows an individual support in detail. Fig. 7 shows a section along the sectional line A-A which is shown in fig. 6. Fig. 8 shows a detail from fig. 7. Fig. 9 shows a 10 further detail from fig. 7. Fig. 10 shows a closure element which makes a rigid connection possible between the roulette wheel and the holding device. Fig. 1 shows a first embodiment of a holding device 10 15 for a roulette wheel 4. The holding device 10 comprises a frame 1 with three supports 2. Each of the supports 2 is oriented vertically, that is to say the three supports 2 are parallel to one another. The supports 2 have in each case one holding element 3 at the upper 20 end. The holding elements 3 project in each case from one of the supports 2. Each holding element 3 projects from in each case another support 2, and in each case another holding element 3 projects from each support 2. The holding elements 3 are of elongate and straight 25 configuration and have the same direction as the respective supports 2. In particular, the supports 2 are configured as rectilinear tubes and the holding elements 3 and the supports 2 are arranged coaxially, that is to say one behind another on the same axis. 30 It is also readily possible that the holding device 10 has more than three supports 2. In the present exemplary embodiment of the invention 35 (shown in figs. 6 to 8), the holding elements 3 comprise a bolt 32 and a securing nut 31. The holding element 3 is connected via the bolt 32 and by means of the securing nut 31 to the support 2. The securing nut WO 2013/010196 - 8 - PCT/AT2012/000189 31 is adhesively bonded with its circumferential-side outer faces on the inner casing side of the tubular support 2. As an alternative, the securing nut 31 and the respective support 2 can also be welded to one 5 another. The bolt 32 is of elongate and approximately cylindrical configuration and, at its one end, has an external thread which is introduced into the securing 10 nut 31. At its other end, the bolt 32 has an axial cylindrical recess, in particular a hole, which has an internal thread on its inner side. Furthermore, the holding element 3 comprises a threaded rod 33. The threaded rod 33 is of cylindrical configuration and has 15 a continuous external thread on its outer casing region. As an alternative, it can be provided that the threaded rod 33 has an external thread only on an end region of the outer casing. The threaded rod 33 is screwed with one end into the internal thread of the 20 bolt 32. At that end of the threaded rod 33 which lies opposite the bolt 32, the threaded rod 33 has a cylindrical recess, in particular a hole, into which a closure element 34 can be introduced. The threaded rod is thickened toward the end at said end of the threaded 25 rod 33, that is to say the outer circumference is widened with respect to the other regions of the threaded rod 33 and has a thickened point 37. The closure element 34 is shown in detail in fig. 10 30 and comprises a head part which is of cylindrical configuration and comprises two end-side recesses 35. Furthermore, the closure element 34 comprises a cylindrical shank 36, the diameter of which the diameter of the cylindrical recess of the By means of 35 said recesses 35, the closure element can be manipulated and, in particular, can be pressed into the cylindrical recess of the threaded rod 33.

WO 2013/010196 - 9 - PCT/AT2012/000189 In the exemplary embodiment which is shown in fig. 1, the bolts 32 of the holding elements 3 have covering disks 38 which are formed integrally in the manner of circular disks on the outer circumference of the bolt 5 32. The covering disks 38 have a diameter which is adapted to the receiving recesses 12 which are shown in fig. 5. The covering disks 38 cover said receiving recesses 12. 10 In the case of one of the supports 2, the covering disk 38 is not shown for illustrative purposes, with the result that the securing nut 31 of the holding element 3 is completely visible. The relative position of the holding element 3 with respect to the support 2 can be 15 varied by rotation of the bolt 32 with respect to the securing nut 31 or of the threaded rod 33 with respect to the bolt 32. That length of the holding elements 3 which projects from the frame 1 and from the supports 2 is therefore adjustable. 20 In one alternative of the invention, the bolt 32 can also be dispensed with, the threaded rod 33 being screwed directly into the securing nut. 25 The supports 2 are arranged parallel to one another and are at the same spacing from a central axis X. The supports 2 are therefore arranged on the outer casing of a cylinder and are in each case at the same spacing in the circumferential direction from the respectively 30 next support 2. The supports 2 of the frame 1 are connected to one another via a linkage 7, 8. The frame has a number of central linkage parts 7 along the central axis X. The 35 spacings between in each case two next central linkage parts 7 are advantageously equally great. In the present exemplary embodiment, merely two central linkage parts 7 are used. Each of the central linkage WO 2013/010196 - 10 - PCT/AT2012/000189 parts 7 is connected by way of in each case three connecting elements 8 to in each case one of the supports 2. In the present exemplary embodiment, the central linkage parts 7 comprise two circularly 5 cylindrical parts 71, 72 (fig. 3) which have a radially running semicircular-cylindrical recess 73 on the outer circumference. If the two circularly cylindrical parts 71, 72 are assembled, the radially running semicircular-cylindrical recesses 73 thus form a 10 circularly cylindrical recess, into which in each case one of the connecting elements 8 can be inserted. The circularly cylindrical parts 71, 72 of the central linkage parts 7 are connected to one another in each case by means of connections, in the present case by 15 means of sealing screws 14 which hold the two circularly cylindrical parts of the respective central linkage parts 7 together. The connecting elements 8 are clamped in the recesses, and a radial relative movement of the connecting elements 8 is ruled out by the 20 clamping effect which is achieved in this way. The connection which is achieved by the sealing screws 14 between the connecting elements 8 and the respective central linkage part 7 is sealed by means of a seal element. 25 The seal achieves a situation where, after setting up and sealing, a change in the position, location, length and/or orientation of the linkage parts 7 with respect to the connecting elements 8 brings about the fracture 30 or cracking of a seal element, and can therefore be determined subsequently. As an alternative, adhesive can also be used as seal element, which adhesive is applied to that surface of 35 the connecting screw and/or sealing screw 14, into which the screwdriver or the respective actuating element engages during the adjustment of the screw position. After the application of the adhesive, WO 2013/010196 - 11 - PCT/AT2012/000189 manipulation by means of a screwdriver or similar actuating element is no longer possible, without damaging or destroying the adhesive layer. Manipulation of the linkage can therefore be determined subsequently 5 without great outlay. Manipulations can be detected quickly by way of regular examination of the seal elements. Furthermore, the individual connecting elements 8 are 10 connected in each case to one of the supports 2. In this preferred exemplary embodiment of the invention, the connecting elements 8 are welded in each case to the supports 2. 15 In an alternative exemplary embodiment of the invention, the connection takes place in turn by means of a screw which penetrates the respective support 2 and the connecting element 8. Once again, that region of the screw which makes the engagement of a 20 screwdriver possible is covered with a seal element, in the present case with an adhesive layer, with the result that the manipulation of the screw leads to the destruction of the adhesive layer. 25 Overall, after setting up, a change in the position, location, length and/or orientation of the linkage parts and/or connecting elements and/or supports leads to the fracture or cracking of a seal element, and can therefore be determined subsequently. 30 In this special embodiment of the invention, furthermore, in each case one fastening element 5 is provided on each of the supports 2, which fastening element 5 makes it possible to fasten the respective 35 support 2 to the floor. The fastening element 5 has a base face in the shape of a circular disk with a number of recesses 52 which are arranged on the circumferential side. Connecting screws are passed WO 2013/010196 - 12 - PCT/AT2012/000189 through said recesses 52, which connecting screws penetrate into the floor below the holding element 10, the fastening element 5 and the respective support 2 and make a rigid connection of the holding element 10, 5 the fastening element 5 and the respective support 2 possible. The connection which is achieved by the connecting screws between the fastening element 5 and the floor can be sealed by means of a seal element. 10 As shown in fig. 9, a fastening element 5 can have a cylindrical projection 51 which points into the support 2 of tubular configuration, the cylinder axis of the projection 51 lying perpendicularly with respect to the 15 disk face of the fastening element 5 in the present exemplary embodiment and passing through the center of the circle of the disk of the fastening element 5. The cylindrical projection 51 has an external thread on 20 its outer surface. The support 2 has an internal thread which matches said external thread on its inner side, with the result that the fastening element 5 can be moved up and down by rotation with respect to the respective support 2. As a result, the length of the 25 supports 2 is in each case of adjustable configuration, and relatively great unevennesses of the floor can be compensated for by the different length of the supports 2. Supports 2 with an adjustable length are advantageous, in particular, in the case of holding 30 devices 10 with a relatively large number of supports 2, since floor unevennesses can be compensated for in an improved manner. A further preferred embodiment of the invention is 35 shown in figs. 4 and 5. Figs. 4 and 5 show a roulette table 30 with a roulette arrangement 20 and a seating table 6. The seating table 6 has a table top 9. A further table top 9a is provided in the region of the WO 2013/010196 - 13 - PCT/AT2012/000189 roulette wheel 4, which further table top 9a is fastened rigidly from below to the table top 9. The table top 9 has a recess in the region of the roulette wheel 4, with the result that merely the further table 5 top 9a which is arranged below the roulette wheel 4 can be seen from above in this region. As described in figs. 1 to 3, a holding device 10 is arranged below the seating table 6. A roulette wheel 4 10 is situated above the seating table. Said roulette wheel 4 has receiving recesses 11 for the holding elements 3, which receiving recesses 11 are adapted to the shape, size and arrangement. The holding elements 3 engage into the respective receiving recesses 11 and 15 make a rigid and stationary connection of the roulette wheel 4 possible to the holding elements 3 and to the holding device 10. The roulette wheel 4 has an upper side and an underside 20 which is stipulated by normal gaming operation. Accordingly, the upper side is that side of the roulette wheel 4 which is typically visible to the gamblers during gaming and is where the roulette ball rolls. As a consequence, the underside of the roulette 25 wheel 4 is that side which faces away from the gambler during gaming. As shown in fig. 5, the holding elements 3 have cylindrical threaded rods 33 which are provided with an 30 external thread. The receiving recesses 11 of the roulette wheel 4 are of piercing configuration, the threaded rods 33 of the holding elements 3 being introduced from the underside of the roulette wheel 4 through said roulette wheel 4 into the receiving 35 recesses 11. The closure element 34 is inserted from the upper side of the roulette wheel 4 into the receiving recess 11. The closure element 34 penetrates with its cylindrical shank 36 into the cylindrical WO 2013/010196 - 14 - PCT/AT2012/000189 recess of the respective threaded rod 33. The closure element 34 is connected to the holding element 3 by being screwed or pressed into the threaded rod 33 of said holding element 3, there being an interference fit 5 between the closure element 34 and the threaded rod 33. Subsequently, the recesses 35 of the closure element 34 are sealed with adhesive or sealing wax, and the closure element 34 can no longer be removed from the receiving recess 11 and/or from the threaded rod 33 10 without engagement into the recesses 35 and the associated destruction of the adhesive layer or the sealing wax. The roulette wheel 4 is clamped between the thickened 15 point 37 of the threaded part and the head of the closure element 34 and is therefore connected in a rigid and stationary manner to the frame 1. The connections which are produced in this way between 20 the holding elements 3 and the roulette wheel 4 are sealed in each case by means of a seal element. A change in the position, location, length and/or orientation of the holding elements 3 and the respective position of the roulette wheel 4 after 25 setting upbrings about the fracture or cracking of a seal element, and can therefore be determined subsequently. A manipulation can therefore be ruled out effectively. 30 Moreover, a seal by means of sealing wax or adhesive can also be produced at the connection between the bolt 32 and the securing nut 31 and at the connection between the bolt and the threaded rod. Comparatively simple examination of the seal is 35 advantageously made possible by way of the arrangement of the closure element on the upper side of the roulette wheel 4.

WO 2013/010196 - 15 - PCT/AT2012/000189 The further table top 9a of the seating table 6 has a recess 12 for each of the supports 2. Each of the supports 2 penetrates in each case one of the recesses 12 without contact. As an alternative, instead of the 5 supports 2, the holding elements 3 which are arranged in each case on the supports can also penetrate the recesses 12. The roulette wheel 4 is held on the holding elements 3 at a level above the surface of the table top 9. In particular, the covering disks 38 are 10 situated above the level of the surface of the further table top 9a and cover the recesses in the further table top 9a. The roulette wheel 4 is spaced apart from the further 15 table top 9a at a spacing of, for example, 1.5 mm. Spacings between 0.5 mm and 3 mm are advantageous. The roulette wheel 4 and the further table top 9a are not in contact with one another here. Furthermore, the roulette wheel 4 and the roulette table 30 are also not 20 connected mechanically to one another, with the result that vibrations from the seating table 6 are not transmitted to the roulette wheel 4. In the embodiment of the invention which is shown in 25 fig. 5, the linkage 7, 8 and the legs 61 of the seating table 6 are nested inside one another and/or reach inside one another, without making contact with one another. It is therefore not possible to remove the holding device 10 with the roulette wheel 4 even though 30 there is no direct mechanical connection between the seating table 6 and the holding device 10.
