7 Claims. (Cl. 27386) This invention relates to game devices, and has special reference to a game board having a plurality of magnets for moving a plurality of tokens over a board in an erratic and Lin-- predictable path.

The primary object of the invention is the provision of a game device wherein a plurality of figures are moved in an erratic path at unredictable speeds over a game board so that a game is produced which has an element of suspense.

A further object is the provision of a game device of the character described which can be manufactured and sold at low cost.

Another object of the invention is the provision of a game device having novel means for supporting the driving magnets and movin the same in an erratic path.

A still further object is the provision of a game device having novel means for interrupting or delaying the movement of the figures on the board.

Other objects and advantages will appear from the following description and the accompanying drawings, in which Figure l is a perspective view of a suitable embodiment of the invention;

Fig. 2 is a view similar to Figure l with the game board removed;

Fig. 3 is a partial section on the line 3-3 of Figure 1;

Fig. 4 is a fragmentary view on a somewhat larger scale showing the manner in which the carrier and magnets are driven;

Fig. 5 is a fragmentary view, partly in section, showing a driving magnet, a figure and the associated figure magnet in cooperative driving relation;

Fig. 6 is a view substantially on the line 5- 5 of Fig. 5, and

Fig. 7 is a fragmentary view somewhat similar to Fig. 3 showing modified structure.

In the embodiment of the invention herein shown for purposes of illustration, the device comprises a body or frame Ii, in this particular instance rectangular in shape and having depending portions as shown at l2 forming supportlegs to space the frame from a table or -t resting place. Supported on the frame a game board designated generally by the numeral t3, the board in this instance being .ecessed downwardly from the upper edge of the name, though this is not essential. The game board It com-prises an area is designated the playing surface area which forms the surface 7 t rests upon the washer 27.

on which the figures move during the operation of the game, and the board also includes areas designated 15, IE, I! and [8, the edges of which are raised. somewhat above the surface area it so as to define the playing area and confine the movement of the figures over the playing area. The upstanding edges of the areas [5 to 18 also serve as obstructions to delay or stop movement of the figures, as will presently more fully appear. If desired the central area l8 may be recessed below level of the playing area, as shown at 28 in Fig. '7 so that whenever a figure moves into the depressed area it is positively eliminated from the game.

Disposed on the frame in a plane below that of the board i3 is a bottom It spaced from the lower surface of the board, and positioned on this bottom are two relatively large disks 2i and 22. Each of these disks is mounted on the base in the manner shown in Fig. 4, a bolt 23 extending through an opening 24 in the bottom and having a head 25 bearing against a washer 2&3 on the lower surface of the bottom. A washer 2? surrounds the bolt at the upper surface of the bottom, and the hub 28 of the disk A third washer 29 rests against the upper end of the hub, and a spacer 3i rests against the washer 25. The upper end of the bolt 23 passes through the game board H3 in the area i8, and a nut 32 on the upper surface of the game board holds the parts in assembled relationship so that the disk 2! may rotate on the bolt 23. The disk 22 is retained in like fashion. The disks 2! and 22 are mounted in edge to edge relationship as shown at 33 (Fig. 2) to provide a friction drive therebetween.

A friction pulley S 5 is carried by a motor drive unit designated generally by the numeral 35 and extends through an opening 33 in the bottom with its edge in spaced relation to the periphery of the disk 2!. The driving mechanism 35 may be of any conventional design, such as a gear head motor, so as to reduce the speed of the pulley 3 3. A satisfactory speed reduction is about to 1 where a 1750 R. P. M. motor is used. Carried on the upper surface of the bottom 19 is an endless tape or belt 3! which may be of any semiflexible non-magnetic material. In the preferred embodiment of the invention this comprises a leather tape or a woven cloth or composition tape of the type commonly used for belting. The distance between the periphery of the disk 2i and the pulley St is such that the tape is frictionally engaged therebetween with sufficient pressure so that rotation of the pulley 3 3 feeds the tape between the pulley and the disl: and likewise causes rotation of the disk 2i, which in turn rotates the disk 22. The disks 2i and 22, being of equal diameter, cause the tape to feed along the incoming side of these two disks in the manner shown in Fig. 2. The tape is of considerably greater length than is required for it to pass around the disks 2| and 22 in a uniform manner, and is suificiently long to cause the same to fold back upon itself a number of times, as will be apparent from Fig. 2. The exact length of the tape is not critical, but there should be a substantial excess. Increase in the length of tape increases the erratic nature of the operation of the device. A guide pulley 38 serves to guide the tape around the disk 22, as will be apparent from Fig. 2.

Mounted on the upper edge of the tape 31 is a series of identical permanent magnets as indicated at 39, these magnets being movable with the tape. While I have shown six of these magnets mounted on the upper edge of the tape, any desired or suitable number may be employed depending upon the size of the device and the type of action desired. Each of these magnets consists of a U-shaped magnet piece formed of efficient magnetic material such as that employed in the more efficient magnets, the center of the magnet being attached to the upper edge of the tape by a saddle $2 of non-magnetic material which passes around the magnet and down along opposite sides of the blade to receive a rivet 43. The upstanding poles of the magnet are each surrounded by a bumper as shown at i of rubber or other non-magnetic material which acts to prevent two of the magnets from coming together in the area in which the tape is looped and thereby prevent free movement of the tape.

The parts are spaced and proportioned so that the upper surfaces of the magnetic pole pieces are in closely spaced relationship to the bottom of the playing board l3, as will be apparent from Figs. 5 and 6, so that these driving magnets move along and swing back and forth under the board [3 in an erratic fashion due to the fact that the tape is fed out from between the pulleys 3d and 2| and the stiffness of the tape causes the tape to slide in an erratic and unpredictable fashion in the area in which the tape is looped and which lies beneath the playing area of the board. The board i3 is in this instance formed of synthetic resin, but it may be formed of any other suitable non-magnetic material or even of sheet metal if the metal is such as to very rapidly lose its magnetism as will be understood by those skilled in the electrical art.

Positioned on the playing area of the board is one or preferably a plurality of figures designated generally by the numeral 3 3, the figiues in this instance being in the shape of a miniature racing automobile having its wheels as indicated at 5-? pinned to the body portion 48 for rotation thereon. Mounted in the bottom of the figure is a permanent magnet 69, the magnet being so mounted as to be in close proximity to the upper surface of the board it as will be apparent from Figs. 5 and 6, the length of this magnet being such as to span the pole pieces of the driving magnets ii and so that as the magnets move along under the board 13, any figure which is disposed on the upper surface of the board IS in close proximity to the magnets 4! will be caused to move along and follow the movement of the driving magnet. It will be observed, however, that because of the erratic movement of the driving magnets, should the tape force the driving magnet to slide laterally of the longitudinal centerline of the figure with a quick movement, the resistance of the figure against the upper surface may be such as to prevent the figure from following the movement of the driving magnet. Likewise, if the figure stries an obstacle in its movement it may be withheld while the drivin magnet moves on.

While I have shown the device arranged to simulate automobile race, it will be obvious that the shape of the figures and the indicia on the game board may be made up to simulate many different games, as, for example, a fox hunt or a mouse hunt, wherein a magnet-containing fox is chased by a number of magnetcontaining dogs all without departing from the basic principles of the invention. In using the device as an automobile racing game in accordance with the indicia herein contained, a plurality of miniature automobiles such as that shown at .5 are arranged in parallelism below the area marked Start in Figure 1. Thereupon, current is supplied to the motor drive unit causing the tape to be fed in an erratic path over the bottom i9. As the magnets come under the figures in the starting area, each magnet will pick up one or more of the figures and start to move the figure along the playing area toward the finish line. As the figures move around the track or playing area, they come into contact with the upstanding edges of the areas l5 through is, causing the driving magnet to move on and the figure to remain until properly removed by a subsequent driving magnet. In order to further render the action erratic, a series of tabs such as indicated at 5| and 52 may be provided which are insertible in slots as shown at 53, 5G, etc., so as to project out over the playing area and serve as a trap for a figure passing in this area. It will be seen that because of the nature of the obstacles and the traps on the surface of the board and the erratic nature of the movement imparted to the driving magnets, it is impossible to predict the figure which may be leading upon the lapse of a predetermined period of operation. If desired, the power to the motor may be supplied through a conventional timer, causing the mechanism to run for a pre-set interval. If desired, ornamental configurations such as the trees indicated at 55 may be supplied on the areas It, [5, 16, I! and It to simulate a natural setting.
