Abstract
Abstract A toy moves downwardly along an incline under the action of gravity in a manner simulating a walking, shuffling, swinging or like motion. The toy is of pendular configuration, having a portion arranged to make rocking contact with a suitably disposed grade, rail or the like affording the incline, and having at least one ball, roller, or wheel which projects displaceably from that portion in such a way that, upon displacement of the or each ball, roller, or wheel, relative thereto, the position of the center of gravity of the whole toy, with respect to the incline, will be altered. The toy may be in the form of a skier and may have sufficient momentum to push obstructions from its path, open gates, etc, or to pick up an object in transit, by means of hooks, magnets, and the like.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
160 words
A toy which will move downwardly along an incline under the action of gravity in a manner simulating walking, shuffling, swinging or like motion, comprising: a portion having a surface arranged to make rocking contact with a suitably disposed incline, said surface having means in the form of a textured area at least at the leading part thereof, in a downhill direction, to minimize slippage relative to such incline; and rolling means, in the form of at least one ball, roller or wheel, which is mounted in and projects displaceably from said portion in such a way that said rolling means may move along the line of said rocking contact either independently of the remainder of the toy or while supporting the remainder of the toy, whereby, upon displacement of said rolling means relative to said portion and along said line, the position of the center of gravity of the whole toy, with respect to the incline, will be altered.
Claim 2
Dependent Claim
160 words
A toy which will move downwardly along an incline under the action of gravity in a manner simulating walking, shuffling, swinging or like motion, comprising: a portion having a surface arranged to make rocking contact with a suitably disposed incline, said surface having means in the form of a textured area at least at the leading part thereof, in a downhill direction, to minimize slippage relative to such incline; and rolling means, in the form of at least one ball, roller or wheel, which is mounted in and projects displaceably from said portion in such a way that said rolling means may move along the line of said rocking contact either independently of the remainder of the toy or while supporting the remainder of the toy, whereby, upon displacement of said rolling means relative to said portion and along said line, the position of the center of gravity of the whole toy, with respect to the incline, will be altered.
Claim 3
Dependent Claim
23 words
A toy according to claim 1, wherein the toy is of inverted pendular configuration and said portion is the base of the toy.
Claim 4
Dependent Claim
42 words
A toy according to claim 1, wherein the means which projects displaceably from said portion is formed from a material that is heavy relative to the material from which at least the greater part of the remainder of the toy is formed.
Claim 5
Dependent Claim
24 words
A toy according to claim 1, wherein the toy comprises a body that is swingable, within limits, about an axis relative to said portion.
Claim 6
Dependent Claim
31 words
A toy according to claim 4, wherein the swingable body is provided with swingable arms, said arms being swingable about said axis relative to said portion independently of the body itself.
Claim 7
Dependent Claim
38 words
A toy according to claim 1, wherein said ball, roller or wheel projects through a slot defined in said surface, the slot extending fore and aft with respect to the intended direction of straight motion of the toy.
Claim 8
Dependent Claim
45 words
A toy according to claim 6, wherein the surface that is arranged to make rocking contact with a suitably disposed incline comprises three successively inclined substantially planar faces and the slot is formed in the center one of said three successively inclined substantially planar faces.
Claim 9
Dependent Claim
36 words
A toy according to claim 6, wherein said ball, roller or wheel is arranged in the slot in such a way as to be movable inwardly of that slot as well as to be displaceable therealong.
Claim 10
Dependent Claim
28 words
A toy according to claim 1, wherein the surface that is arranged to make rocking contact with a suitably disposed incline comprises three successively inclined substantially planar faces.
Claim 11
Dependent Claim
39 words
A toy according to claim 9, wherein said faces are tangential to an imaginary cylindrically curved surface whose axis of curvature is substantially coincident with the center of an enlargement of the toy that is remote from said portion.
