Patent number: 6540577Abstract: An amusement system that includes a miniature toy skateboard and the mechanism for engaging and lifting the miniature toy skateboard. The miniature toy skateboard is less than six inches long and is referred to as a finger board in the toy industry. The finger board is manufactured to have a top surface that is either magnetic or attracted to a magnet. The mechanism for engaging and lifting the finger board is a magnet that is held within an external object, such as a ring or a toy figure. A manually adjustable spacer is positioned in front of the magnet. To engage the finger board with the external object, the length of the spacer is minimized and the finger board is brought into close proximity with the magnet. The magnetic field created by the magnet attracts the finger board and holds the finger board against the external object. To detach the finger board, the length of the spacer is increased. This moves the external object out beyond the effective range of the magnetic field of the magnet.Type: GrantFiled: September 11, 2000Date of Patent: April 1, 2003Inventors: Webb Nelson, Chan Yuk Ng

Patent number: 5810640Abstract: Novel magnetic gel materials useful as toys, playthings and novelties and a method for making same. These materials should also prove useful in other fields where ferrofluids and other magnetic liquids have found use when the plastic mechanical properties of the gel are not a limitation. The novel invention produces a magnetic material that exhibits the soft, thixotropic properties of play gels. A gelatinous material such as a silicone gel has a fine magnetic powder dispersed throughout by kneading into a substantially uniform mixture at ambient/room temperature. The advantage of this method for producing magnetic gel over the alternative of adding a gelling agent to an existing ferrofluid are simplicity and the ability to choose the properties of the gelatinous material independently of the need for a carrier fluid. Various types of toy applications include resilient plastic covered forms, template action figure body forms, flowers, and volcanoes with various shaped openings.Type: GrantFiled: June 26, 1996Date of Patent: September 22, 1998Assignee: General Research and Device CorporationInventors: Thomas L.

The playthings have limbs, such as arms, or other appendages such as tails or trunks, extending from their bodies, the limbs or appendages being provided with connection elements, such as magnets (14), for removably attaching limbs together to simulate "hand holding" or to attach to metal surfaces or to "pick up" metal objects. In alternative embodiments the magnets are arranged so that they will repel each other so that certain limbs or appendages will not attach to each other. In another embodiment the playthings can be manipulated by the thumb and fingers, such as in the form of recesses (44) provided in the clothes or by strings (38), such as in the form of a marionette (46).Type: GrantFiled: October 24, 1991Date of Patent: November 8, 1994Inventor: Sandra L.

Patent number: 5188555Abstract: A magnetic novelty item is disclosed for use as a plaything, toy, amusement, diversion, game piece, or instructional aid. The item includes an enclosed container having magnets secured at opposite ends thereof with opposite magnetic poles facing the interior of the container (north at one end and south at the other). At least one additional magnet is received in the container in such a way that its magnetic poles are always oriented toward like magnetic poles of the magnets at the ends of the container while yet remaining movable in the space between the ends.Type: GrantFiled: January 6, 1992Date of Patent: February 23, 1993Inventor: Joseph H. Zbegner

Patent number: 5167564Abstract: A clothes rack for use with doll clothing and the like is arranged, wherein spaced side walls mount a hanger supporting rod orthogonally therebetween underlying a roof plate for use in storage of various components of doll accessories. A trio of connecting rods at lower distal ends of the side walls define a shoe-receiving slot for reception of shoes therewithin. The hanger structure of the invention is arranged to optionally include a mounting frame to accommodate elongated doll clothing of various sizes and is formed with magnet members to effect a spacing of the hangers when arranged in adjacency relative to one another by magnets of confronting like polarity. The mounting frames are further provided with fluid reservoirs to direct various scented fluids about an overlying wick structure of the mounting hanger organization.Type: GrantFiled: December 16, 1991Date of Patent: December 1, 1992Inventor: Murray L. Lord

Patent number: 5165347Abstract: A vehicle levitation and guidance system (20) is provided which levitates a vehicle (22) over a roadbed (28) through the use of thin permanently magnetized strips (32, 34) located in the vehicle and the roadbed. The strips are oriented with like magnetic poles adjacent to generate a repelling force. The vehicle is guided along the roadbed by sliding engagement of the walls (37) of a channel (30) in the roadbed with pins (36) descending from the vehicle. The vehicle is propelled along the roadbed by contact with a set of rotating wheels (42, 42').Type: GrantFiled: April 26, 1991Date of Patent: November 24, 1992Inventor: Thomas V. Wagner

Patent number: 5112052Abstract: The base of a game board is formed by a mount member having a groove having a form containing straight line parts, curved line parts, intersecting parts, and angled parts. The groove forms the traveling path of a traveling toy. Solid bodies containing iron-including materials or magnetic materials are inserted into the groove of the mount member so that the upper surface of the solid bodies are leveled with the upper surface of the mount member. The mount member is affixed to a substrate and covers the entire surface of the substrate. A covering paper is affixed to the mount member and covers the entire surface of the mount member to hide the traveling path. When a traveling toy which is provided with a magnet is driven on the covering paper, the traveling toy runs along and over the solid bodies which are in the groove in the mount member which is covered by the covering paper. The covering paper comprises a jigsaw puzzle and can also be used as a book cover.Type: GrantFiled: July 23, 1990Date of Patent: May 12, 1992Assignees: Yonezawa Corporation, Toranosuke YamauraInventor: Toranosuke Yamaura
