10 Claims, 4 Drawing Figures MAGNETIC AMUSEMENT DEVICE This invention relates generally to an amusement device but may be utilized for other purposes. A disc is mounted on support structure for rotation about an axis. The disc is preferably made from nonmagnetic material such as plastic but may be made partially of magnetic material adjacent its axis of rotation and of nonmagnetic material adjacent its periphery. A first magnet is supported by the disc at or adjacent one of its peripheries such as the outer periphery.
A second magnet is supported adjacent to but spaced from the periphery of the disc. The second magnet is supported by a carrier mounted for movement in a direction generally parallel to the axis of rotation of the disc. As the second magnet is manually or mechanically moved in a direction generally parallel to the axis of rotation of the disc, it induces magnetic forces which cause the disc to rotate about its axis. Skill can be attained whereby the movement of the second magnet occurs while poles on the magnet supported by the disc move past the second magnet. With practice, it is possible to cause the disc to rotate at a rate of about 120 rpm. v
The present invention may be utilized as a toy for purposes of amusement. The present invention may be utilized for other purposes such as for testing dexterity and timing. The second magnet may be mounted for reciprocation or for oscillation adjacent to and spaced from the periphery of the disc.
The magnets used are preferably of the flexible type sold in strip form. This facilitates the ease with which the device of the present invention may be constructed and at the same time minimize the costs involved. The magnet on the disc is preferably supported within a groove adjacent the periphery of the disc.
It is an object of the present invention to provide a novel device for causing a disc to rotate as a function of and in response toreciprocation or oscillation of a second magnet adjacent the periphery of the disc.
It is another object of the present invention to provide a novel amusement device of the magnetic type.
It is another object of the present invention to provide apparatus for inducing rotation of a disc in response to reciprocation or oscillation of an actuator without touching the disc.
Other objects will appear hereinafter.
For the purpose of illustrating the invention, there is shown in the drawing a form which is presently preferred; it being understood, however, that this invention is not limited to the precise arrangement and instrumentality shown.
FIG. 1 is a perspective view of a device in accordance with the present invention.
FIG. 2 is a sectional view taken along the lines 22 in FIG. 1.
FIG. 3 is a sectional view taken along the lines 33 in FIG. 1.
FIG. 4 is a perspective view of another embodiment structure 12, other materials such as metal and wood, as well as laminates may be utilized.
A circular disc 14 is' rotatably supported about its axis by means of a pin 16. The pin 16 is guided at its lower end by means of an aperture 18 in the support structure 12. The upper end of the pin 16 extends through a guide hole or aperture 22 in the bracket 20. The bracket 20 is angled so as to have a cantilever arm overlying the disc 14 and an arm fixedly secured to and supported by the support structure 12.
The disc 14 is preferably made from an inexpensive, non-metallic material such as a polymeric plastic. The suitable polymeric plastic for the support structure 12, disc 14, and the bracket 20 include polystyrene, polyvinylchloride, acrylics, etc. The disc 14 is provided with a groove or recess adjacent its outer peripheral surface. A magnet 24 is mounted within the groove or recess and retained therein in any convenient manner such as by clips, adhesive, force-fit, etc. The magnet 24 is preferably a flexible strip magnet. A wide variety of such magnets are sold commercially. One suitable magnet is sold commercially by the B. F. Goodrich Company under the trademark Koroseal. While the entire disc 14 may be made from a polymeric plastic, only the outer peripheral portion containing the magnet 24 need be of a nonmagnetic material.
The disc 14 may be supported in any desired elevation with respect to the upper surface of the support structure 12 in any convenient manner. Thus, the pin 16 could have a shoulder on which the disc 14 rests. As shown, such shoulder is accommodated by means of a flange 26 secured to the pin 16.
A guide support member 28 is connected to the support structure 12 and located adjacent the periphery of disc 14. A carrier 30 having a magnet 32 is reciprocably supported by the member 28. Carrier 30 is in the form of a sleeve which surrounds the member 28. Preferably the member 28 and carrier 30 are rectangular so as to preclude relative rotation whereby the magnet 32 will be immediately adjacent to but spaced from the periphery of disc 14. Member 28 and carrier 30 are preferably made from non-metallic materials as described above.
The disc 14 may have indicia 34 and 36 imprinted thereon 'to designate poles. When the magnet 32 is slightly below the plane of the disc 14 and opposite pole 36, the disc 14 is induced to rotate in one direction about the axis of pin 16. When the pole 34 is adjacent to the magnet 32, the magnet 32 should be raised so as to be slightly above the plane of disc 14. It the timing of this relationship is attained, the disc 14 will be induced to rotate even faster. If the magnet 32 remains v slightly below the plane of disc 14 when the pole 34 moves past it, the disc 14 would be induced to slow down. Thus, it will be seen that some dexterity and skill is required to cause the disc 14 to rotate and continue to rotate faster as the magnet 32 is caused to reciprocate in timed relationship with the rotation of the disc 14.
In FIG. 4, there is illustrated another embodiment of the present invention. The device in FIG. 4 is designated generally as 10' and is identical with the device 10 except as will be made clear hereinafter. Hence, corresponding elements are provided with corresponding primed numerals.
In the device 10, the carrier 30' is supported at one end of a flexible cantilever guide support member 38.
One end of the guide support member 38 is secured to the support structure 12. The carrier may be caused to oscillate from a static position wherein the magnet on carrier 30' is slightly above the plane of the disc 14. The magnet on carrier 30' may be moved or oscillated to a position slightly below the plane of disc 14 by pressing downwardly on the flexible guide support member 38' adjacent its free end.
In each of the above described embodiments, the magnet which is manually or mechanically moved to induce rotation of the disc 14 is spaced from the periphery of the disc 14 by a distance of approximately one-eighth of an inch. The thickness of the outer wall of the groove or recess for retaining the magnet 24 may be approximately one-sixteenth of aninch. These dimensions are, within limits, variable. The magnet 32 and 32 are preferably slightly concave so as to conform with the radius of curvature of the disc 14 and 14 but may be straight if the radius of curvature is large. Further, the magnet 32 and 32 may assume the shape of animate objects. Likewise, the indicia 34 and 36 may assume various configurations including arrowheads, circles, animate objects, etc.
The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof and, accordingly, reference should be made to the appended claims, rather than to the foregoing specification as indicating the scope of the invention.
