Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 241 words
An acrobatic toy robot adapted to be placed upright upon a supporting surface and propelled therealong comprising a hollow body having a vertical length dimension, a pair of arms rotatably mounted upon said body each having a longitudinal length dimension, power means mounted within said body and engaging said arms to effect simultaneous rotation thereof relative to said body, first wheel means operatively connected to said power means to propel said robot, second wheel means freely rotatable and aperatively associated with said first wheel means to support said robot on a supporting surface in an upright position, and means to facilitate falling of said robot from said upright position when said robot is inclined therefrom, said facilitating means including stop means operative to engage said second wheel means to prevent rotation thereof, said longitudinal length dimension of each of said arms being of such a predetermined measurement relative to said vertical length dimension of said body that said arms extend nearly To said supporting surface when said robot is placed in an upright position on said supporting surface, whereby rotation of said arms relative to said body is operative, due to the relationship between said vertical length dimension of said body and said longitudinal length dimension of said arms, to effect a complete somersault movement of said robot by engagement of said arms against said supporting surface to return said robot to an upright position when it has been displaced therefrom.
Claim 2
Dependent Claim 241 words
An acrobatic toy robot adapted to be placed upright upon a supporting surface and propelled therealong comprising a hollow body having a vertical length dimension, a pair of arms rotatably mounted upon said body each having a longitudinal length dimension, power means mounted within said body and engaging said arms to effect simultaneous rotation thereof relative to said body, first wheel means operatively connected to said power means to propel said robot, second wheel means freely rotatable and aperatively associated with said first wheel means to support said robot on a supporting surface in an upright position, and means to facilitate falling of said robot from said upright position when said robot is inclined therefrom, said facilitating means including stop means operative to engage said second wheel means to prevent rotation thereof, said longitudinal length dimension of each of said arms being of such a predetermined measurement relative to said vertical length dimension of said body that said arms extend nearly To said supporting surface when said robot is placed in an upright position on said supporting surface, whereby rotation of said arms relative to said body is operative, due to the relationship between said vertical length dimension of said body and said longitudinal length dimension of said arms, to effect a complete somersault movement of said robot by engagement of said arms against said supporting surface to return said robot to an upright position when it has been displaced therefrom.
Claim 3
Dependent Claim 52 words
A robot according to claim 1, wherein said hollow body comprises an upper portion having shoulder portions projecting laterally thereacross, with said rotatable arms being secured at said shoulder portions, said hollow body being of a generally cylindrical shape and having said upper portions thereof formed into a radially outwardly swelling configuration.
Claim 4
Dependent Claim 95 words
A robot according to claim 1, wherein said hollow body includes a bottom portion having a rear end, a forward side, a rearward side and a head having a top surface, and wherein said facilitating means further including an inclined sled-like portion formed at the rear end of said bottom portion of said hollow body to facilitate falling of said robot onto its rearward side, said robot further comprising a projection formed on said top surface of said head and having a rearwardly sloping configuration to facilitate falling of said robot onto said forward side.
Claim 5
Dependent Claim 66 words
A robot according to claim 3, wherein said bottom portion of said hollow body includes a forward end, with said first wheel means being disposed at said forward end, said bottom portion being of a substantially square shape and including at said forward end means adapted to contact the supporting surface for facilitating regaining by the robot of an upright position after it has fallen therefrom.
