(40) FIGS. 1 to 3 are different views of an example of a module element 12 of a modular ball track system which comprises a plurality of such module elements, all of which have the exterior shape shown of a regular hexagon of equal size and each form on their upper face one or more ball track sections which can be combined with one another by putting the module elements together.
(41) The example of a module element 12 shown in FIGS. 1 to 3, like all further module elements of the modular ball track system, has an upper face 14, a lower face 16 opposite the upper face, and six lateral surfaces 18. In the module element 12 shown, two ball track sections 20 and 22 are formed on the upper face 14, which ball track sections have a cross-section having the shape of a segment of a circle and are let into the surface 14 of the module element 12. A first ball track section 20 begins in the left lateral surface 18 in FIG. 1 of the module element 12 and extends in curved form to the immediately adjoining top lateral surface 18 in FIG. 1 of the module element 12, the first ball track section 20 passing through each of the two lateral surfaces 18 so that the ball track can be continued by adding further module elements. A second ball track section 22 begins in a left, lower lateral surface 18 of the module element 12 shown in FIG. 1 and runs with a less pronounced curve to a next-but-one, right lateral surface 18 in FIG. 1 of the module element 12. It will be appreciated that the beginning and the end of the ball track sections 20, 22 merely depend on the direction in which a ball runs through the corresponding ball track section. The beginning of a ball track section can therefore at the same time be the end of the ball track section, depending on the direction in which the ball runs through the ball track section.
(42) As can be seen particularly clearly in FIGS. 1 and 2, the example of a module element 12 and all further module elements of the modular ball track system are disk-shaped overall, that is to say the height of the lateral surfaces 18 extending at least approximately at right angles to the upper face 14 is significantly smaller than the dimensions of the module element 12 in the other two spatial directions of a Cartesian coordinate system.
(43) As can best be seen in FIGS. 2 and 3, a plug base 24 protrudes from the lower face 16 of the example of a module element 12 and also from all further module elements of the modular ball track system, which plug base in the exemplary embodiment shown likewise has the form of a regular hexagon, the sides of which are parallel to the lateral surfaces 18 of the hexagon forming the exterior shape of the module element 12. As can be seen in FIG. 3, the example of a module element 12 is a part produced by a plastics injection molding process, for which reason the lower face 16 is for the most part open. In order to increase the stability of such a module element 12, reinforcing ribs 26 extend between outside walls 28 forming the lateral surfaces 18 and inner walls 30 forming the plug base 24.
(44) The modular ball track system further includes a base plate 32 shown in FIGS. 4 and 5 having a plurality of regularly arranged, here hexagonal recesses 34, each of which serves to receive one plug base 24. The recesses 34 are arranged on the base plate 32 in a grid which here is honeycomb-shaped, the grid dimension s of the grid corresponding to the incircle diameter of the regular hexagon forming the exterior shape of the module elements, that is to say the diameter of the largest circle which can be inscribed in the hexagon forming the exterior shape of the module elements.
(45) By means of the plug base 24, module elements such as the example of a module element 12 can thus be fitted into recesses 34 of the base plate 32, module elements fitted into recesses 34 of the base plate 32 that are immediately adjacent to one is another lying flush against one another with in each case one of their lateral surfaces 18 so that a ball track section formed on a module element can merge into a ball track section formed on an adjoining module element in an almost transition-free manner. As can readily be understood from considering FIGS. 3 and 5 together, the incircle diameter d of each recess 34 is smaller than the incircle diameter, corresponding to the grid dimension s, of the hexagon forming the exterior shape of a module element.
(46) The base plate 32 shown in FIG. 4 is composed of a plurality of base plate segments 36, one of which is shown in an enlarged representation in FIG. 5. For the interlocking connection of the base plate segments 36 in the base plate plane, each base plate segment 36 is provided at its edges with here dovetail-shaped projections 38 and dovetail-shaped cutouts 40, by means of which the individual base plate segments 36 can be hooked together. The form of the projections 38 and cutouts 40 shown is merely by way of example. In other forms of base plate segments which are not shown, the projections and cutouts can have a different shape, and both projections and cutouts can be present on an edge of a base plate segment. Furthermore, the base plate segments 36 of the exemplary embodiment shown here are made of a stable cardboard, as is used, for example, in the production of conventional jigsaws, but the base plate segments can also be made of a different material, for example of plastics material, a metal or of wood.
(47) It should have become clear from the above description that module elements such as the example of a module element 12 can be combined on the base plate 32 to form a ball track by placing the individual module elements next to one another on the base plate 32 according to a desired run of the ball track. However, the module elements do not necessarily have to be arranged immediately next to one another on the base plate 32, since the modular ball track system according to the present invention further comprises connecting rails 42, which are shown in FIGS. 6 and 7. Although only one connecting rail 42 of a predetermined length is shown in FIG. 6, the modular ball track system can also comprise connecting rails of a different length, for example connecting rails of three different lengths, the lengths of which have a ratio to one another of 1:2:3, that is to say the longest connecting rail is three times as long as the shortest connecting rail.
(48) The connecting rail 42 is formed substantially of two rods 44, here having a circular cylindrical cross-section, which are arranged parallel to one another and form a section of the ball track, the rods 44 being connected to one another to form a ladder-like structure by a plurality of cross-members 46 (here three) which extend beneath the ball track transversely to the rods 44. Each rod 44 has two free ends 48 which are bent downwards in the manner of a hook. By means of these hook-like ends 48, the connecting rail 42 can be hooked into a pair of hooking openings 50 which are formed in the example of a module element 12 (and also in every other module element) at the end or beginning of each ball track section formed on a module element (see FIG. 1). More precisely, the hooking openings 50 are let into the ball track on both sides of the ball track immediately adjacent to the point at which a ball track section passes through a lateral surface 18 of the module element 12.
(49) The cooperation of the free ends 48, bent downwards in the manner of a hook, of a connecting rail 42 with the hooking openings 50 of a module element 12 is shown in greater detail in FIGS. 8a and 8b. FIG. 8a shows a configuration in which the connecting rail 42 connects a module element 12 to a further module element (not shown) situated in the same plane, while FIG. 8b shows a configuration in which the connecting rail 42 connects a module element 12 at a higher level to a module element at a lower level (not shown). The two configurations shown in FIGS. 8a and 8b are possible despite a constant length of the connecting rail 42 because the hooking openings 50 allow the free ends 48 of the connecting rail 42 a predetermined degree x of freedom of movement in the longitudinal direction of the connecting rail 42 and thus in the longitudinal direction of the ball track.
(50) Connecting rails 42 thus serve to bridge a gap between two module elements which are not arranged immediately adjacent to one another, which can be either at the same level or at different levels. In order to reduce the risk that a ball moving along the ball track will fall out of the ball track as it moves from a module element to a connecting rail or vice versa, each cross-member 46 arranged close to the free ends 48 of the rods 44 is lengthened and raised up at the sides in order thus to form guards 52 on both sides of the ball track close to the transition from a connecting rail 42 to a module element, on which guards a ball can be supported if necessary (see FIG. 7). In order to make the transition between a connecting rail 42 and a module element as jolt-free as possible for a ball rolling on the ball track, each rod 44 is further provided on its upper side with a ramp-like elevation 54 in a region close to each free end, which elevation lifts a ball rolling on the connecting rail 42 slightly shortly before it passes over onto a module element. In the form shown, the connecting rails 42 can advantageously be produced as injection-molded plastics parts.
(51) That the module elements of the modular ball track system do not all have to be in the same plane has already been touched upon. In order to be able to arrange module elements such as the example of a module element 12 at different heights, the ball track system comprises column elements, of which a column element 56 is shown in FIGS. 9 and 10. In conformity with the module elements, the column elements 56 have the exterior shape of a regular hexagon with a slightly smaller incircle diameter compared with the module elements. In order that the column elements 56 can be freely combined with module elements and the base plate 32, each column element 56 has on its upper face a recess 34, the arrangement and dimensions of which correspond to a recess 34 of the base plate 32. The plug base 24 of a module element 12 thus fits into this recess 34. Each column element 56 further has on its lower face a plug base 24, which corresponds in shape, arrangement and dimensions to the plug base 24 of the module element 12. By using one or more column elements 56 stacked one above the other and then fitting a module element 12 to the uppermost column element 56, module elements can thus be arranged at many different heights. For finer height gradation, the ball track system can contain column elements of different heights, for example column elements whose height h is only half that of the column element 56 shown in FIGS. 9 and 10.
(52) By means of the above-described column elements 56, larger regions of the ball track according to the invention can also be arranged at a higher level than the base plate 32. There is used for this purpose an intermediate plate 58 shown in FIG. 11 which, like the base plate 32, has a plurality of regularly arranged, hexagonal recesses 34 for receiving in each case one plug base 24, 24. The recesses 34 of the intermediate plate 58 are arranged in the same honeycomb-shaped grid as the recesses 34 of the base plate 32 and have the same grid dimension s. On the lower face of each recess 34 of the intermediate plate 58 there is formed a plug base 24 which fits, for example, into the recess 34 of a column element 56. By supporting an intermediate plate 58 on the base plate 32 by means of a plurality of columns each constructed from column elements 56, it is possible to produce intermediate levels of the ball track, which make the run of the ball track more interesting and more exciting. In order to make regions of the ball track located beneath an intermediate plate 58 visible, the intermediate plate 58 shown is advantageously made of transparent plastics material.
(53) Different forms of the module elements of the modular ball track system according to the invention will be described in greater detail hereinbelow. FIG. 12 shows a module element 12 whose peripheral form and dimensions correspond to those of the module element 12 shown in FIG. 1 but which has a central opening 60 which here is in the form of a through-opening and communicates with a plurality of ball track sections 20 formed on the upper face 14 of the module element 12 and serves to receive a functional insert which is associated with at least one of the ball track sections 20. FIGS. 13a to 13d show several examples of functional inserts.
(54) FIG. 13a shows a functional insert 62 in the form of a tray, which can serve, for example, as a target which all the balls are to reach. The balls that reach the target then collect in the functional insert 62.
(55) FIG. 13b shows a functional insert 62 in the form of a ramp, which can serve, for example, to catch balls from a higher level and transfer them through an outlet 64 to one of the ball track sections 20. Alternatively, the functional insert 62 can serve as a starting point of a ball track.
(56) FIG. 13c shows a functional insert 62 which receives a ball that arrives via a ball track section 20 of the module element 12 and guides it into the central through-opening 60 of the module element 12, so that this ball falls from a higher level into a level located beneath it.
(57) Finally, FIG. 13d shows a functional insert 62 which communicates with each of the three ball track sections 20 of the module element 12 and has three depressions 66, in each of which a ball (not shown) can be placed. If a further ball then falls centrally from above onto the functional insert 62, for example using the above-described functional insert 62 in a module element 12 arranged in a plane located above, the three balls located in the depressions 66 splash in the direction of the three ball track sections 20 of the module element 12 thereof.
(58) The above-described functional inserts 62, 62, 62 and 62 are only by way of example. Many further functional inserts are possible. Also, the central opening 60 of the module element 12 does not necessarily have to be in the form of a through-opening but can instead have a bottom (not shown), if a ball is not required to fall down through it.
(59) FIG. 14 shows a further module element 12, which differs from the module element 12 shown in FIG. 1 only in that the two ball track sections 20 and 22 formed on its upper face 14 cross.
(60) FIG. 15 shows a module element 12 which leads three ball track sections 20, 21 and 22 to a common outlet, at which a finish rail 68 similar to the connecting rail 42 of FIG. 6 is hooked. This finish rail 68 serves not to bridge a gap between two module elements but to receive balls which reach the target in succession. The finishing placings of the balls are obtained from the order in which the balls are received by the finish rail 68.
(61) Module elements which contain an action element in addition to the at least one ball track section formed on their upper face will be described hereinbelow.
(62) FIG. 16 shows, in plan view, a module element 70 having a points function. On the upper face 14 of the module element 70 there are formed two ball track sections 71, 72 which together have a Y-shaped form. A points element 74 is pivotably mounted on the upper face 14 of the module element 70 above the Y-shaped part of the ball track and has a long guide arm 76 pointing towards the foot of the Y and two short control arms 78 pointing towards the legs of the Y. In the position of the points element 74 shown in FIG. 16, an incoming ball at the foot of the Y is guided by the guide arm 76 of the points element 74 into the right-hand ball track section 72, where it strikes the right-hand control arm of the two control arms 78. The ball striking this control arm 78 in this manner serves to pivot the points element 74 counter-clockwise, so that the ball is able to roll further and the guide arm 76 now rests against the foot of the Y on the opposite side of the ball track, so that the next ball that rolls into the module element 70 at the foot of the Y is guided into the left-hand ball track section 71, whereupon the points element 74 pivots into the position shown in FIG. 16 again. Accordingly, the module element 70 guides balls that roll into the module element at the foot of the Y alternately into the ball track section 71 and the ball track section 72. The points element 74 can of course also be pivoted by hand, if desired.
(63) FIG. 17 shows a module element 80 having a so-called vortex function. For this purpose, the module element 80 is provided with a region 82 in the form of a funnel, which has a central opening 84 at the bottom. Balls entering the module element 80 via the ball track sections 20 first move in a vortex line shape in the region 82 in the form of a funnel and then fall down out of the module element 80 through the central opening 84.
(64) FIG. 18 shows a module element 86 having a start function for three balls. For this purpose, three ball receivers 88 are formed on the upper face of the module element 86 in a central region, in each of which receivers one ball (not shown) can be placed. A release component 90 which covers the balls and is spring-mounted normally to the upper face of the module element 86 prevents, in an upper position into which it is urged by the spring, the balls arranged in the ball receivers 88 from rolling out by in each case a barrier 92 which protrudes upwards from the associated ball track section 20. By pressing down in the center of the release component 90 against the spring force, the barriers 92 are lowered to such an extent that balls located in the ball receivers 88 are at the same time able to roll free.
(65) FIG. 19 shows a module element 94 having a so-called Gauss cannon function. In order to achieve this function, a ball track section 96 extending across the module element 94 is blocked by a disk-shaped magnet 98 which is arranged transversely to the ball track section 96 and is received in a bridge-shaped holder 100. One or two balls of magnetic material can be placed on both sides of the magnet 98, which balls are prevented from rolling away by the magnetic force. If a further ball then rolls into the ball track section 96 from one side and strikes the balls already located therein, a ball on the side of the magnet 98 remote from the impact is released by the impulse of the striking ball.
(66) FIG. 20 shows a module element 102 having a ball-lift function. On the upper face 14 of the module element 102 there is formed a ball track section 104 having a ramp 106, the level of which is higher than the start of the ball track section 104. A lever 110 is pivotably mounted on a bridge-like holder 108 which spans the ball track section 104. The lever 110 is provided at its lower end in FIG. 20 with a release member 112, which has a short arm 113, which projects downwards in the position shown, and a long arm 114, which extends at a right angle thereto in the direction towards an incoming ball. To the opposite end of the lever 110 there is fixed a weight 116. In the starting position of the lever 110 shown in FIG. 20, the lever is in a so-called over-dead-center position, that is to say the weight 116 is located with its center of gravity slightly to the right of a plane normal to the upper face 14 of the module element 102 and running through the holder 108. A ball rolling into the module element 102 strikes the short arm 113 of the release member 112, whereby the lever 110 is pivoted counter-clockwise out of its over-dead-center position, so that the weight, which is now located to the left of the mentioned plane running through the holder 108, continues and accelerates the pivoting of the lever 110. The long arm 114 of the release member 112 contacts the ball and moves it up the ramp 106.
(67) FIG. 21 shows a further module element 118 having a more pronounced ball-lift function. Similarly to the module element 102 described above, a lever 110 is pivotably mounted on a holder 108 and provided with a weight 116. At its end opposite the weight 116, the lever 110 is provided with a cup 120 for receiving a ball. The free edge of the cup 120 abuts a spring-mounted release rail 122 mounted in the ball track section 20 and is thereby prevented from pivoting. A ball rolling into the ball track section 20 depresses the release rail 122 with its weight as it rolls into the cup 120, so that the lever 110 is able to pivot freely. The weight 116 pivots the lever 110 clockwise, whereby the ball in the cup 120 is conveyed to the elevated level of the ball track section 20.
(68) FIG. 22 shows a module element 124 having a gate function. For this purpose, an arcuate gate element 126 spans a ball track section 125 formed on the upper face 14 of the module element 124. In the position shown, the gate element 126 prevents a ball from passing to the part of the ball track section 125 situated on the other side of the gate element. Connected to the gate element 126 is a spoon-shaped release member 128, which is associated with a further ball track section 129 of the module element 124. Between the spoon-shaped release member 128 and the arcuate gate element 126, the gate formed of the above-mentioned two parts is pivotably mounted at 130. If a ball arrives at the spoon-shaped release member 128, it depresses it with its weight and at the same time raises the gate element 126, so that a ball that was initially held in the ball track section 125 is allowed free passage.
(69) FIG. 23 shows a module element 132 having a sling or catapult function. The function of this module element 132 is similar to that of the module element 118 described with reference to FIG. 21, but the module element 132 has only a one-sided lever 110 having the cup 120. The lever 110 is biased for pivoting in the clockwise direction by means of a rubber band 134. As soon as a ball rolling into the cup 120 has depressed the release rail 122, the lever 110 pivots clockwise in a flash owing to the resilient bias of the rubber band 134 and catapults the ball in the cup 120 to the right.
(70) FIG. 24 shows a module element 136 whose function is similar to that of the module element 102 described with reference to FIG. 20. Unlike the module element 102, however, an incoming ball is not lifted to a higher level by the release member 112 after overcoming the over-dead-center position of the lever 110, but the hammer-like weight 116 strikes the ball from behind and accelerates it to the right in FIG. 24.
(71) FIG. 25 shows a module element 138 having a ball release function by means of another ball. Similarly to the module element 102, a lever 140 is pivotably mounted, but this lever 140 has two arms 141, 142 arranged at right angles to one another. A first arm 141 is arranged above a launch ramp 143 of the module element 138 and has a circular opening, the diameter of which corresponds to the diameter of a ball that is used. As shown, a ball can in this manner be held at the upper end of the launch ramp 143 by the first arm 141. A second arm 142 of the lever 140, which second arm is directed perpendicularly downwards in FIG. 25, carries a release member 144. A ball rolling into the module element 138 strikes the release member 144, whereby the lever 140 pivots slightly in the counter-clockwise direction and thereby releases the ball held by the first arm 141.
(72) FIG. 26 shows a module element 146 having a firing function for another ball. Arranged on the module element 146 is a firing device 148 having a spring-biased piston 150. To the left and right of the firing device 148 there are two release members 152 on the module element 146, which release members can be depressed by the weight of an incoming ball in order to release the biased piston 150. A ball situated in front of the piston 150 is then fired into the adjoining ball track section.
(73) FIG. 27 shows a module element 154 having a three-way distribution function. Similarly to the module element 70 described with reference to FIG. 16, the module element 154 also has ball track sections with a generally Y-shaped profile. However, the ball track section formed by the foot of the Y additionally extends over the entire module element 154, so that a ball rolling into the foot of the Y can be conveyed in three different directions. This is effected by means of two points elements 156, 157 arranged on the right and left of the central ball track, each of which points elements has a long guide arm 158, 158 and a short control arm 159, 159, which as shown are arranged at an angle to one another. The pivotable points elements 156, 157 are shown in FIG. 27 in a position which occurs when a first ball has already left the module element 154 through the ball track outlet located at bottom right. The next ball is then, as shown, guided into the ball track outlet of the module element 154 located at top left and then positions the points element 156 in a position that frees the central passage.
(74) FIG. 28 shows a module element 160 having a bell function. For this purpose, a bell 162 is so arranged on the module element 160 that the edge of the bell cap projects into a ball track section 162 which is formed on the upper face 14 of the module element 160. A ball passing through the ball track section 162 strikes the bell 162, so that a bell sound sounds.
(75) FIG. 29 shows a module element 164 having a crossover function. For this purpose there is formed on the module element 164 a ball track section 165 which extends in the form of a circular ring and communicates with two outlets 166, 167. A ball entering the circular ball track section 165 through one outlet 166 is thus guided in a circle and leaves the module element 164 through the other outlet 167.
(76) FIG. 30 shows a module element 168 on which there is formed a ball track section 170 in the form of a loop.
(77) FIG. 31 shows a module element 172 having a bridge function. For this purpose, the module element 172 is provided on its upper face 14 with a ball track section 173 extending in a straight line over the entire module element, and further has a ball track section 174 which crosses the ball track section 173 in the manner of a bridge.
(78) FIG. 32 shows a module element 176 having a checkered flag function. For this purpose, a checkered flag 178 which spans the module element 176 in the manner of a bridge is pivotably mounted on both sides of a target funnel 179, at the deepest point of which there is a release member 180. If a ball rolls into the target funnel 179, it depresses the release member 180 with its weight, whereby the pivotably mounted checkered flag 178 is pivoted upwards out of its position shown in FIG. 32 in order to indicate that a ball has reached the target.
(79) FIG. 33 shows a module element 182 having a so-called splash function. The function of this module element 182 corresponds to the function of the functional insert 62 described with reference to FIG. 13d.
(80) FIG. 34 shows a module element 184 having a so-called leg-up function. On the module element 184 there is formed a first ball track section 185 which ends beneath a ball track section 186 which spans the ball track section 185 in the manner of a bridge. In the bridge-like ball track section 186, exactly above the ball track section 185, there is a circular hole 187 in which a ball that crosses the bridge-like ball track section 186 normally gets caught. If, however, there is a ball at the end of the ball track section 185, this ball fills the hole 187 to such an extent that a ball crossing the bridge-like ball track section 186 is able to roll further. Alternatively, a ball rolling into the ball track section 185 has the effect, when a ball is already in the hole 187, that this ball is freed by the ball rolling into the ball track section 185 and is able to roll further.
(81) FIG. 35 shows a module element 188 having a so-called cascade function. In order to achieve this function, there is fastened to the module element 188 a funnel 190 having a mouth 192 which leads to an outlet of the module element 188. Two inlets of the module element 188 are each provided with a release member 194 which can be depressed by the weight of an incoming ball. A gate (not shown) arranged in the mouth 192 is unlocked by the depression of the release member 194, so that all the balls in the funnel 190 fall downwards and roll through the mouth 192 into the adjoining ball track.
(82) FIG. 36 shows a module element 196 having a collect and transfer function. For this purpose, the module element 196 is provided with a pivotably and eccentrically mounted cup 198 into which balls from a higher level of the ball track are able to fall from the left in FIG. 36. As soon as a specific number of balls, for example three balls, have fallen into the cup 198, the cup 198 overcomes its dead-center position and tips to the other side, so that the balls collected therein are released into the adjoining ball track section situated at a lower level.
(83) FIG. 37 shows a module element having an impulse function. For this purpose, a rod 202 which extends longitudinally is arranged on the module element 200, which rod projects beyond the module element 200 in both directions and reaches into adjoining ball track sections. If one end of the rod 202 is struck by a ball, the impulse thereof travels through the rod 202 to the opposite end thereof and can be transmitted to a ball that is in contact with the opposite end.
(84) FIG. 38 shows the module element of FIG. 37 in a modified configuration. An impulse is again transmitted from one ball to another ball through the rod 202, but this impulse transfer is achieved according to FIG. 38 by a rotation of the rod 201
