Abstract
Abstract A hand-held toy is disclosed by which the manual dexterity and concentration of the user is challenged. The toy in its preferred embodiment constitutes a continuous Mobius ring formed from an elongated band having grooves disposed in both sides thereof, the grooves defining a raceway for a rolling ball-like playing piece and with the band being twisted about its longitudinal axis through an odd number of turns and having its ends permanently joined together. An aperture is disposed in the band which communicates with the grooves to either side of the band. The aperture being selectedly closed by one-way door means. A handle is provided to be gripped by the user, the handle being disposed across the Mobius ring and defining an approximation of the diameter. The toy is utilized by placing one or more rolling ball-like playing pieces or marbles in the grooves and then, through manipulation of the Mobius ring, the ball can be rolled in the grooves through a distance of up to 720° or, the ball can be rolled through the open door and aperture through a shorter angular distance to facilitate playing action. A removable arched cover can be provided over one of the grooves adjacent the door to further facilitate playing.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
189 words
A hand-held toy for challenging the manual dexterity and concentration of the user, said toy comprising: an elongated band having grooves disposed in both sides thereof defining a raceway for a rolling ball-like playing piece said band being twisted about its longitudinal axis through an odd number of turns and having its ends permanently joined together to define a continuous Mobius ring; an aperture disposed in said band communicating with the grooves to either side of said band and having a diameter sufficiently large to receive said ball-like playing piece therein; door means positioned in said aperture to selectively open and close same; an arcuate arched cover disposed over the groove along a selected distance on one side of said band at the region of said door; and handle means disposed on the Mobius ring coupled to said band for providing an area to be gripped by the user and from which the toy can be manipulated by hand to selectively allow the ball-like playing piece to roll in said grooves over an angular distance of up to 720° and through said door to opposite sides of said band.

A hand-held toy for challenging the manual dexterity and concentration of the user, said toy comprising: an elongated band having grooves disposed in both sides thereof defining a raceway for a rolling ball-like playing piece said band being twisted about its longitudinal axis through an odd number of turns and having its ends permanently joined together to define a continuous Mobius ring; an aperture disposed in said band communicating with the grooves to either side of said band and having a diameter sufficiently large to receive said ball-like playing piece therein; door means positioned in said aperture to selectively open and close same; an arcuate arched cover disposed over the groove along a selected distance on one side of said band at the region of said door; and handle means disposed on the Mobius ring coupled to said band for providing an area to be gripped by the user and from which the toy can be manipulated by hand to selectively allow the ball-like playing piece to roll in said grooves over an angular distance of up to 720° and through said door to opposite sides of said band.
Claim 3
Dependent Claim
12 words
A toy as defined in claim 1, wherein said cover is removable.
Claim 4
Dependent Claim
38 words
A toy as defined in claim 1, wherein said door means opens in one direction only and, when opened, additionally defines a deflecting stop for the ball-like piece causing the playing piece to be deflected through said aperture.
Claim 5
Dependent Claim
27 words
A toy as defined in claim 1, wherein said handle means is disposed across the Mobius ring to define an approximation of the diameter of said ring.
Claim 6
Dependent Claim
12 words
A toy as defined in claim 1, wherein said cover is transparent.
Claim 7
Dependent Claim
126 words
A hand-held toy for challenging the manual dexterity and concentration of the user, said toy comprising: an elongated band having an S-shaped cross-section forming offset, open-sided, generally U-shaped grooves disposed in both sides thereof defining a raceway for a rolling ball-like playing piece, said band being twisted about its longitudinal axis through an odd number of turns and having its ends permanently joined together to define a continuous Mobius ring; and handle means disposed across the Mobius ring to define an approximation of the diameter of said ring for providing an area to be gripped by the user and from which the toy can be manipulated by hand to selectively allow the ball-like playing piece to roll in said grooves over an angular distance of 720°.
