Definitions

  • the present invention relates to drive assemblies and is especially, but not exclusively, concerned with drive assemblies for use with gaming machines, sometimes referred to as fruit machines or amusement machines.
  • gaming machines It is well known in Germany for gaming machines to include a number of adjacent reels marked around their circumferential surfaces with symbols such as fruit. In operation, the reels are caused to spin about a common axis by pulling on a handle or pressing a button. When the reels come to a standstill, the positions of the symbols on the different reels in relation to one or more predetermined lines decide whether or not a player has won.
  • Each of the reels is typically formed from a strip presenting the symbols and a drum-like support carrying the strip.
  • Current regulations in Spain forbid the use of gaming machines in which symbol-presenting strips are carried by drum-like supports of a diameter exceeding 39mm - the conventional answer to the problem of "small drum diameter" has been to provide a magnifying system whereby the necessarily small symbols on special strips carried by the drum-like supports can be viewed more comfortably by a player.
  • a drive assembly in accordance with the present invention, comprises a strip arranged in a continuous loop and a plurality of parallel and rotatable supports around which the strip is wrapped.
  • the rotatable supports there are three of the rotatable supports, none of which has a diameter exceeding 39mm.
  • the strip is formed of a translucent plastics material permitting back illumination of symbols of conventional size presented thereby, but the strip could be of an opaque material such as white card.
  • At least one, but preferably each, of the rotatable supports is either formed with or associated with means for transforming rotation of the support to translation of the strip.
  • one or more or all of the rotatable supports is or are formed with at least one series of circumferentially spaced studs, which locate sequentially in at least one corresponding row of longitudinally spaced apertures formed in the strip.
  • all of the rotatable supports are wrapped around by at least one endless belt, which is or are secured to only a corresponding edge portion of the strip.
  • the endless belts each of which is flexible and is secured to a respective one of the edge portions of the strip in a manner allowing a central portion of the strip to remain unobstructed.
  • the or at least one of the belts may be moulded of a plastics material and may present a groove for receiving the adjacent edge portion of the strip.
  • One or more lugs may be provided in the groove (s) for locating with one or more complementary notches provided in the adjacent edge(s) of the strip.
  • the or at least one of the belts may be capable of providing a friction drive or may present a series of ribs or recesses for non-slip engagement with complementary recesses or ribs presented by at least one of the rotatable supports.
  • the ribs and recesses may be rounded or serrated and may be located immediately adjacent to one another or separated from one another.
  • a tab may also be presented by either or both of the belts as part of an optical device for providing information to electronic circuitry.
  • a pair of parallel and non-rotatable supports are provided to which the rotatable supports are rotatably secured.
  • the non-rotatable supports are formed as plates of generally triangular outline with the rotatable supports extending therebetween and being located at or near the corners thereof, but plates of other shapes would be possible.
  • an electrical stepper motor (or other drive means) rotates only one of the rotatable supports, which thus positively moves the strip wrapped therearound whilst the other rotatable supports merely idle, in order to bring symbols presented by the strip into successive view through one or more windows (or other inspection means) .
  • Figure 1 is a schematic perspective view of a first drive assembly
  • Figure 2 is a front view of one of the endless belts shown in Figure 1;
  • Figures 3 and 4 are enlarged cross-sectional views taken respectively along the lines III-III and IV-IV shown in Figure 2;
  • Figure 5 is a schematic perspective view of a second drive assembly viewed from the front.
  • Figure 6 is a schematic perspective view of the second drive assembly viewed from the back.
  • FIG. 1 to 4 show a drive assembly 10 including: a strip 12 arranged in a continuous loop (part omitted for clarity) ; two symmetrical endless belts 14 each secured to only a respective edge portion of the strip 12; and three parallel supports 16 formed as rotatable skeletal drums around which the belts 14, and thus the strip 12, are wrapped.
  • One of the supports 16 is driven by an electrical stepper motor 18 whose drive shaft 20 is connected by a belt 22 to a flanged disk 24.
  • the shaft 20, belt 22 and disk 24 may all be toothed as in a conventional timing belt drive.
  • the disk 24 is carried centrally of a driven shaft 26 whose ends carry half-flanged disks 28 rotatably mounted to respective adjacent side plates 30.
  • both of the other supports 16 may be of the same construction and each of the three supports 16 may be integrally moulded of a plastics material.
  • All of the half-flanged disks 28 are similar, each including a drum-like peripheral surface 32 which itself includes a plurality of circumferentially-spaced three- sided grooves 34.
  • the grooves 34 could be of different outline and spacing so that the peripheral surfaces 32 could have the appearance of, for example, toothed wheels or gear wheels.
  • the purpose of the grooves 34 is to enable a non-slip engagement with complementary longitudinally-spaced three- sided ribs 36 formed on the endless belts 14 (these are not clearly shown in the schematic perspective view in which rounded surfaces have been indicated by flat surfaces as in typical computer generated drawings) .
  • Each of the endless belts 14 may be integrally moulded of a plastics material such as polyurethane.
  • a plastics material such as polyurethane.
  • the strip 12 which may be a translucent plastics strip of generally conventional construction having symbols 50 printed or formed thereon, is a push fit within the grooves 44 of the endless belts 14 which are themselves located by engagement with and between the half-flanged disks 28.
  • the drive assembly 10 may be associated with one or more illumination units, located in lamp housing 52, and may be mounted in a gaming machine in whatever orientation is appropriate, by use of fixings 54.
  • the accompanying Figures 5 and 6 show a drive assembly 100 including: a strip 112 arranged in a continuous loop; a plurality of parallel and rotatable supports 116 around which the strip 112 is wrapped; and a pair of parallel and non-rotatable supports 130 to which the rotatable supports 116 are rotatably secured.
  • the strip 112 may be a translucent plastics strip of generally conventional construction having symbols 160 printed or otherwise formed thereon.
  • a row of apertures 162 may be formed near an edge of the strip 112 such that the apertures 162 are spaced apart along the length of the strip.
  • a second row of similar apertures may be formed near the other edge of the strip.
  • each of the rotatable supports 116 may be integrally moulded of a plastics material to the same shape, even though only one of the supports 116 is here to be driven.
  • a conventional toothed timing belt 122 may connect drive means such as an electrical stepper motor to a toothed disc 124 carried centrally of a driven shaft 126, which is in turn to drive the strip 112 wrapped therearound whilst the other rotatable supports 116 merely idle.
  • drive means such as an electrical stepper motor to a toothed disc 124 carried centrally of a driven shaft 126, which is in turn to drive the strip 112 wrapped therearound whilst the other rotatable supports 116 merely idle.
  • each of the rotatable supports 116 are formed with respective discs 128. If the strip 112 is to have one row of the apertures 162, only one of the two driven discs 128 on the driven shaft 126 needs to be formed with a series of circumferentially spaced studs 164. If the strip has two rows of the apertures 162, both of the two driven discs are formed with a respective series of the studs 164. Alternatively, as appropriate, additional or all of the discs 128 may be provided with corresponding series of circumferentially spaced studs 164. It will be appreciated that, in use, the studs 164 sequentially engage with the apertures 162 to locate he strip correctly as the strip is driven.
  • the non-rotatable supports 130 may be of a rigid metal construction capable of being secured to a pair of end brackets 166 which are themselves capable of being secured through holes 167 to the body of a gaming machine.
  • each of the non-rotatable supports 130 may be a plate of identical shape to the other, for convenience, even though not all of the mountings and other features are then utilised.
  • each of the plates 130 may have an elongate cutout 168 and a pair of slotted offset tongues 170.
  • a plastics lamp housing 152 may be a snap fit.with just one of the cutouts 168 and a stepper motor may be adjustably secured to just one pair of the tongues 170.
  • the lamp housing is fixed to one of the plates 130, whereas the stepper motor is fixed to the other of the plates 130.
  • each of the plates 130 may have a hole 172 to which an optic unit 174 can be secured, although only one of holes 172 is utilised.
  • the lamp housing 152 may incorporate a plurality of individual lamp sections 176, the stepper motor may be associated with a pair of sprung loaded belt tensioners 179 (only one shown) for tensioning the belt 122, and the optic unit 174 may have a pair of arms 180 between which can pass an optic tab stuck or otherwise fixed to the inner surface of the strip 112.
  • the driven shaft 126 is mounted at opposed bearings 182 whereas the other two rotatable supports 116 are sprung mounted in bearings 184 - the springs keep the correct tension in the strip 112, but can be compressed to disengage the studs 164 from the apertures
  • struts 186 extend between opposed pair of holes 188 to provide rigidity and the correct spacing between the plates 130.
