Abstract

A free-standing rolling book comprises plural sheets, bound along one marginal edge. In the preferred embodiment, the book cover includes printed matter depicting a wheeled vehicle having wheel wells disposed adjacent the bottom edge of the book. Respective wheels are rotatably cantilever mounted at each of the wheel wells. The dimensions of the sheets and the wheel span of the wheels are selected such that the wheels support the sheets in a free-standing position so as to permit the book to roll without external support. The wheel span should be at least two-sevenths of the distance between the center of gravity of the book and the wheel-supporting surface, and, in the preferred embodiment, is one-seventh of the book'"'"'s height.

Claims

1. A free-standing rolling book comprising:

plural sheets, bound along one marginal edge to form said book, said sheets including a front cover and a back cover with interior pages therebetween;

printed matter, disposed on the exterior of at least one of said covers, depicting a moving object having support locations, said support locations disposed adjacent a bottom marginal edge of said at least one of said covers;

plural wheels, for supporting said sheets in a free-standing position when all of said sheets are vertical and in contact with adjacent sheets such that said book is in a closed upright position, at least some of said wheels disposed at respective support locations depicted by said printed matter; and

means for individually, rotatably, cantilever mounting said wheels along respective axes passing through the covers of the book such that said wheels project outwardly in cantilever fashion from said front and back covers to permit said book to be opened to expose the interior pages thereof, said wheels being mounted in positions so related to the center of gravity of said book and being configured to provide a wheel span, between the outer edge of a wheel mounted on said front cover and the outer edge of a wheel mounted on said back cover, measured in a direction normal to said covers, such that said mounting and configuration enable the rotatably mounted wheels to support said sheets in said free-standing position to permit said book to roll without external support.

2. A free-standing rolling book, as defined by claim 1, wherein said moving object depicted by said printed matter comprises a wheeled vehicle, and said wheel locations depicted by said printed matter comprise the wheel wells of said wheeled vehicle.

3. A free-standing rolling book, as defined by claim 1, additionally comprising means for detachably fastening said sheets together to prevent said sheets from separating while said book is rolling on said rotatably mounted wheels.

4. A free-standing rolling book, as defined by claim 3, wherein said fastening means comprises a strap, permanently affixed to one of said covers, and detachably affixed to the other of said covers.

5. A free-standing rolling book, as defined by claim 1, wherein said front cover, back cover, and interior pages have the same dimensions.

6. A free-standing rolling book, as defined by claim 5, wherein at least one of the marginal edges of said sheets is sculptured to generally follow the contour of at least a portion of the periphery of the moving object depicted by said printed matter to enhance the three-dimensional realism of said book.

7. A free-standing rolling book, as defined by claim 1, wherein said plural wheels comprise at least four wheels, two of which are cantilever mounted on said back cover and two of which are cantilever mounted on said front cover, one of said wheels on said front cover disposed adjacent to one of said wheels on the back cover to provide a front wheel pair, and the other of said wheels on the front cover disposed adjacent the other of said wheels on the back cover to provide a rear wheel pair.

8. A free-standing rolling book, as defined by claim 7, wherein the axes of rotation of the wheels comprising said front wheel pair lie along a common line and the axes of rotation of the wheels comprising said rear wheel pair lie along a common line, said common lines passing through the interior pages of said book.

9. A free-standing rolling book, as defined by claim 1, wherein said wheel span is at least two-sevenths of the distance between the center of gravity of said book and a surface on which said wheels rest.

10. A free-standing rolling book, as defined by claim 9, wherein said book is generally rectangular, and said wheel span is at least one-seventh of the distance between a surface on which the wheels rest and the top of said book.

11. A free-standing rolling book, as defined by claim 1, wherein the ground clearance distance between said covers and a surface on which said wheels rest is no greater than 1/4 inch.

12. A free-standing rolling book, as defined by claim 1, wherein said cantilever mounting means comprises hub means for spacing said wheels from said covers to prevent said wheels from rubbing against said covers during rotation.
