Abstract

Abstract A ball rolling toy including a ball and an oblong device that includes two side rails, an intermediate anti-wedge rail, two handles and two hubs connecting the device together. The side rails are positioned in parallel relation to one another and connected together by connecting means or hubs. Each side rail has a side track positioned about its outer inside edge that is a mirror image of the other side track. The distance between each side track is nearly equal to the diameter of the ball. The antiwedge rail is connected to the hubs. The anti-wedge rail has an anti-wedge track having an outline that is shaped similar to but of a smaller scale than the outline of each side track. The distance between the anti-wedge track and each side track is equal to the radius of the ball times the square root of two. The centerline of each rotatable handle is offset from the centerline of the other handle. Each handle projects outwardly from opposite sides of the device.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 127 words
A ball rolling toy comprising a ball, and a track device including at least one handle connected on opposite sides and adjacent opposite ends of said device, two side rails positioned from one another in parallel relation at a distance nearly equal to the diameter of a ball, side tracks on the outer inside edge of each side rails, enabling a ball having a diameter greater than the spacing between said tracks to roll around the rails, connecting means positioned between and connecting the side rails together, and an anti-wedge rail having an outer edge track with an outline generally identical in shape to the outline of said side tracks but of a smaller scale, said anti-wedge rail connected between said side rails by said connecting means.
Claim 2
Dependent Claim 127 words
A ball rolling toy comprising a ball, and a track device including at least one handle connected on opposite sides and adjacent opposite ends of said device, two side rails positioned from one another in parallel relation at a distance nearly equal to the diameter of a ball, side tracks on the outer inside edge of each side rails, enabling a ball having a diameter greater than the spacing between said tracks to roll around the rails, connecting means positioned between and connecting the side rails together, and an anti-wedge rail having an outer edge track with an outline generally identical in shape to the outline of said side tracks but of a smaller scale, said anti-wedge rail connected between said side rails by said connecting means.
Claim 3
Dependent Claim 21 words
A ball rolling toy as set forth in claim 1, wherein, said side rails are identical mirror images of one another.
Claim 4
Dependent Claim 37 words
A ball rolling toy as set forth in claim 2, wherein, said outer edge track is positioned from said side tracks a distance nearly equal to the radius of the ball times the square root of two.
Claim 5
Dependent Claim 35 words
A ball rolling toy as set forth in claim 3, wherein, said connecting means are hubs positioned between the side rails, and a rotatable handle connected to each side of said device having offset centerlines.
