Definitions
- the present invention relates to cyclic image viewers, such as those used in recreational machines, and more particularly to viewers in which the images are carried by a continuous, flexible band along which they are uniformly distributed.
- the improvements of the invention are aimed at achieving perfect guidance of the continuous band, enabling its position to be adjusted perfectly according to any practical requirement, the support of the continuous band and its driving means furthermore constituting a compact assembly of reduced volume.
- a set of viewers is used, normally three or four, in which a set of figures or symbols appear cyclically as if they were carried by a set of rotating drums, said viewers showing a certain combination at the end of each play, possibly corresponding to a prize.
- Spanish utility models 261.860, 270.005, 271.429, 287.665, 9100716, 9100717 and 9202785 describe examples of this type. See also GB-A-2 150 335.
- the housing of these viewers is fixed to the corresponding support plate by means of "clips" and, although these clips make assembly and disassembly an extremely fast and simple process, when the time comes to actually disassemble the viewer an excessive deformation force is often applied to the tab or tabs which constitute the clip, causing said tab to break such that the entire support plate has to be replaced, with the resulting cost and complexity which this implies.
- the improvements proposed by the present invention have been conceived in order to solve this problem in an entirely satisfactory way, and are therefore based on the use of a totally different system for guiding the continuous band, based not on the use of rollers but on the use of two symmetrical grooves provided in the opposing faces of two plates which constitute the chassis of the viewer, said grooves being designed to receive the corresponding edges of the continuous band with a considerable amount of play and therefore forming a closed trajectory corresponding to that which said band is supposed to follow.
- this new system for guiding the band enables it to follow practically any straight or curved trajectory, and can therefore be adapted according to the specific requirements of each case.
- said grooved plates which constitute the chassis, and which obviously are conveniently joined by means of spacers so as to adopt a configuration which is appreciably rectangular and relatively extended in the direction of the cyclic movement of the images are each provided with grooved sections on their major edges, one straight and one curved, such that a particular cyclic viewer can be used in either of two positions without having to be modified, in one of said positions the band moving in a straight line past the viewing window and in the other the band following a convex curved trajectory.
- said grooves in the plates which constitute the chassis which have an appreciably peripheral trajectory, as well as defining the straight and curved sections described above, undergo a sharp inflection at a mid-point of one of the minor sides, defining a kind of internal loop designed for fitting the continuous band to the inevitable pulling drum.
- This abrupt inflection of the continuous band may be helped by a pair of rollers which, apart from guiding the band as in the case of the rollers of conventional viewers, help it to follow the sharp bends along its trajectory, it being possible to fit two more freely rotating rollers at the other two inflections which the band undergoes along the other minor side of the chassis.
- an intermediate plate is positioned at a mid-point between the two above mentioned plates, in the half other than the one in which the pulling drum is located, said intermediate plate being located inside the continuous band and constituting the support for the motor and the drive transmission unit for said pulling drum.
- Said motor may be a D.C. motor, but is preferably an impulse or stepper motor
- the drive transmission has the form of a reduction box to which the axis of the motor is connected through the intermediate wall, said reduction box being provided with the corresponding set of gears, with the particular characteristic that said axis of the motor, apart from constituting the drive transmission element, constitutes the means of supporting said reduction box, said box being also provided with a grooved tab by means of which it is fixed to the intermediate wall with the help of a screw, such that before said screw is tightened said reduction box can be pivoted about the axis of the motor in order adjust the tension in the transmission belt which drives the drum or roller that pulls the continuous band, as will be seen later on.
- a freely rotating pivoting plate to be mounted on the output axis of the motor next to the transmission pulley which drives the pulling drum or roller, said pivoting plate being provided with an arm ending in a small roller designed to press against the transmission belt and act as a means of tensing said belt, the pivoting plate therefore being permanently pulled by a spring which tends to make it pivot in the appropriate direction.
- the end of the pulling drum or roller opposite the end at which the driven pulley is fitted ends in a miniature pinion which is housed in a small housing in the chassis with the help of a corresponding closing cover, said housing also housing a reduction crown gear whose output axis, which passes through said cover, is connected to a disc provided with a groove at a point on its perimeter and with a line of small holes inside the level of said groove designed to activate a double optical reader which can detect both the passing of said groove as well as that of each of said holes, thereby enabling both the zeroing of the continuous band as well as the position of each of the images to be controlled.
- said optical reader and more particularly the printed circuit board associated with it, is mounted directly onto the chassis of the viewer with the help of guides made in the hollow interior of said chassis and which can be accessed from the outside.
- the transmission ratio between said pinion and said reduction crown gear is such that the passing of the holes in the plate in front of the optical reader is correctly synchronized with the motion of the images of the cyclic viewer assembly.
- a device which is designed to be conveniently fixed to the housing of said viewer, said device taking the form of a double cam which opposes the toothed tab on which it acts and which can adopt two positions 180° out of phase, in one of said positions, and together with the housing itself of the element in question, it constitutes a kind of clamp which immobilizes the toothed tab in a clamped position, whilst when it is rotated into the opposite position and the toothed tab is freed, it acts on the inner face thereof, deforming it against its natural elasticity, by a small amount in order to avoid the deterioration of said tab but enough to detach it from the corresponding rebate in the element which it was fixing.
- the toothed tabs which fix the support element are clamped and fixed under normal conditions, such that said element is perfectly stable, whilst when it is necessary to disassemble said support element they enable the retaining tabs to be easily elastically deformed without the risk of causing their deterioration.
- Figure 1 shows an exploded perspective view of a cyclic image viewer according to the improvements which form the object of the present invention.
- Figure 2 is an internal front elevation view of one of the plates which make up the viewer shown in the previous figure.
- Figure 3 is an exploded view similar to that of figure 1, showing an alternative embodiment of the viewer in which a pair of rollers help to guide the continuous band.
- Figure 4 is a representation similar to those of the previous figures, showing another alternative embodiment of the viewer in which there are four rollers which help to guide the continuous band.
- Figure 5 shows the viewer of figure 3 in the assembled state where the working face is a flat section of the continuous band.
- Figure 6 shows the same viewer as the previous figure, where this time the working face is a convex curved section of the continuous band.
- Figure 7 shows a partial perspective view of the cyclic image viewer of the previous figures showing the reduction unit in detail.
- Figure 8 is a lateral elevation view of the assembly shown in the previous figure.
- Figure 9 is a cross section of the same assembly taken through the axis of the pulling roller.
- Figure 10 shows a perspective view of a cyclic image viewer similar to that of the previous figures but in which the drive transmission unit has been modified.
- Figure 11 is another perspective view of the viewer shown in the previous figure seen from the opposite lateral face.
- Figure 12 shows a perspective and exploded detail of the part of the viewer where the transmission belt tensioner is fitted.
- Figure 13 shows another perspective and exploded detail of the viewer, this time at the position of the reduction unit which drives the control disc.
- Figure 14 shows a partial perspective view of a viewer like the one shown in the previous figures fitted to the corresponding support plate and fixed thereto by means of clips provided with the detachment and clamping device which constitutes another of the characteristics of the invention.
- Figure 15 is an upper or external plan view of the cam which forms part of said device.
- Figure 16 is a lower plan view of the same cam.
- Figure 17 shows a profile of the cam.
- Figure 18 shows a detail in cross section taken along the line A-B of figure 15.
- Figure 19 shows another detail in cross section, this time taken along the line C-D of figure 16.
- the cyclic viewer according to the improvements described comprises a pair of symmetrical parallel plates 1,2 which may be substantially thin, as can be seen in figure 1, and which are joined by means of spacers 3 or by any other suitable means, said plates 1 and 2 having the particular characteristic that their opposing faces are provided with grooves 4 designed to house the respective edges of the continuous band 5 that carries the figures, said grooves being more than sufficiently deep to ensure the stability of the edge regions of the continuous band 5 inside them, the width of said grooves ensuring that said band can move with play.
- the basically rectangularly shaped groove 4 in the plates 1 and 2 follows a trajectory in which it is possible to define a straight section 4' along to one of the major sides of the plates, and an appreciably convex curved section 4'' corresponding to the opposite side such that, depending on the position of the viewer assembly relative to the viewing window of the machine, the continuous band presents a straight trajectory, as in the case of figure 5, or a convex curved trajectory, bearing a considerable likeness to a drum of considerable diameter, as shown in figure 6.
- the groove 4 which defines the trajectory of the continuous band 5 undergoes a sharp internal inflection along of the minor sides of the plates 1 and 2, defining a section in the form of a loop 6 in which said groove may even disappear, becoming a simple step open to the outside between the inflection zones 7, the pulling drum 8 being positioned within the area defined by said loop 6 of each plate 1,2, said pulling drum being provided at its edges with classical lines of teeth 9 which act on the holes 10 in order to pull said band.
- a smaller intermediate plate or wall 11 is provided between said plates 1 and 2 in the part of the chassis furthest away from the area in which the pulling drum 8 is located, one of the faces of said intermediate wall or plate 11 constituting the support for the motor 12 which drives said drum, its other face constituting the support for the reduction unit 13 which is driven by said motor 12 and which drives the pulley 14, preferably toothed, which in turn, and with the help of a belt 15, drives another pulley 16 conveniently joined to the axis of the pulling drum 8.
- the belt 15 and the two pulleys 14 and 16 may be substituted by two directly or indirectly engaged toothed crown gears.
- the intermediate wall or plate 11 may in turn be joined to the lateral plates 1 and 2, within the grooves 4, by means of spacers 3', as shown in figure 1, or by means of internal walls 17 that emerge from said plates 1 and 2 following a trajectory similar to that of the grooves 4, as is shown in figure 3, such that the intermediate wall 11 is located between the openings defined by these walls 17 and is conveniently fixed thereto.
- these discs 19 it is also possible for these discs 19 to take the form of rollers 20 which are also free to rotate on the chassis, and that these rollers 20 work together with two other rollers 21 situated at the other two inflection points or zones of the continuous band 5 next to the other two vertices of the plates 1 and 2 which constitute the chassis.
- rollers 20 and 21 of the embodiment shown in figure 4 imply the need for a greater force to move the continuous band 5, and therefore in said example shown in figure 4 a D.C. motor 22 is used instead of the stepper motor 12 of the previous examples.
- the structure described is complemented with any conventional means of detecting and controlling the position of the continuous band 5 at all times, such as for example by means of opto-couplers which may be situated at any point on the continuous band itself, using the holes 10 thereof, colours, bar codes, etc., or said means may be separate from the continuous band, on elements which move in synchronization with it, connected for example to the transmission output 13, although the reading method used does not affect the basis concept of the invention in any way.
- the plates 1 and 2 may be provided close to their vertices with cut-outs 23 for fitting lamp holders 24 for illuminating the working area of the continuous band, although again this does not affect the basic concept of the invention which, as has been said above, is based fundamentally on the system for guiding the continuous band based along the grooves 4 made in the plates 1 and 2, making it possible to define straight trajectories 4' and convex curved trajectories 4'' for said continuous band, which in turn enables the cyclic viewer to be adapted according to any practical requirements.
- the axis 25 of said motor passes through the wall 11 and enters the reduction box 13, said reduction box being situated on the other side of said wall 11 and supported at two points, the axis 25 itself and a tab 26 provided with a slightly curved elongated groove or hole 27 whose centre of curvature coincides with the axis 25 and through which passes a screw 28 to fix it firmly to the intermediate wall 11 after having pivoted said reduction box 13 as necessary in order to adjust the tension in the transmission belt 15 that connects the pulley 14, joined to the output axis 29 of said reduction box 13, to the pulley 16, joined in turn to the axis 30 of the pulling roller 8, the amount by which said pulleys 14 and 16 protrude from the plate 1 of the viewer being such that the belt 15 operates at a minimum distance from said plate, as can best be seen in the cross section shown in figure 9, implying a minimal increase in volume of the viewer in question.
- a pivoting plate 38 is mounted on said output axis 29 of the drive unit, said pivoting plate being preferably provided with a collar 39 which moves inside another collar 40, coaxial with the axis 29 and emerging as a single piece from the intermediate wall 11, said plate 38 being provided with an elongated hole 41 through which passes a screw 42 joined to an appendix 43 laterally adjacent to the collar 40, said screw 42 acting as a limiting stop for the pivoting movement of the plate 38 which is pulled by a spring 44 connected between a small hole 45 in said plate and a pivot 46 that emerges from the intermediate wall 11, said plate 38 being further provided with an arm 47, parallel to its pivoting axis, on which is mounted a small, freely rotating roller 48 which presses against the transmission belt 15 as a means of keeping it tense.
- the ratio between the pinion 49 and the reduction crown gear 51, and the diameter of the plate 54, are such that the groove 55 passes in front of the optical reader 57 each time that the continuous band 5 completes a full trajectory, whilst the displacement in time between the holes 56 coincides in turn with the displacement in time between the images 60 of the continuous band 5 as they pass the viewing windows 61,61'.
- each viewer 1 assembly to the corresponding support plate 62, as shown in figures 14 and onwards, in correspondence with at least one of the toothed tabs 63 which constitute the means of fixing the viewer 1 to said support plate 62, when the tooth 64 of said tab 63 is snapped into a stepped rebate 65 in the element 1, said element 1 incorporates a cam 66 joined to said element 1 by means of an axis 67 which enables it to rotate freely.
- the cam 66 consists of a flat body, indicated by the reference 66, provided with a central hole 68, through which passes said pivot axis 67, and further provided at its edge with a stepped rebate 69 whose opening 70 is substantially widened, the depth of said rebate 69 depending on the thickness of the toothed tab 63, and more particularly on the corresponding height of the external surface of said toothed tab 63 above to the corresponding face of the body or chassis of the viewer 1, such that when in the clamped position shown in figure 14, said tab 63 is gripped or restrained between the cam 66 and the viewer 1 and is thereby immobilized with no possibility of play.
- said cam 66 On the half of the cam 66 furthest away from the stepped rebate 69 mentioned above, and parallel to its opening 70, said cam 66 is provided with a wide bezel 71, said bezel being outwardly oriented, i.e. oriented away from the viewer 1, and designed to act on the inclined surface 72 of the tooth 64 of the tab 63 when the cam is rotated in the opening or unclamping direction, thereby causing said tab 63 to elastically deform so that its tooth 64 is released from the stepped rebate 65 of the element 1, but at the same time said deformation being the minimum necessary to achieve this effect such that there is absolutely no risk of said tab 63 breaking by forcing it excessively.
- the axis of rotation 67 of the cam 66 is positioned on the element to be fixed 1 at a distance relative to the toothed tab 63 such that when said cam is in an intermediate position in which the edge 73, where the opening 70 leading to the stepped rebate 69 and the bezel 71 are located, is parallel to the far, free end 74 of the toothed tab 63, these elements do not interfere with each other, enabling the element 1 to be fitted to the support plate 62 bY simple pressure as if the release and clamping device did not exist and, from such an intermediate position, if the cam is rotated in one direction it causes the toothed tab 63 to become clamped and if it is rotated in the other direction it causes said tab 63 to be elastically deformed sufficientlY to release the viewer 1.
