Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
277 words
A mechanical doll toy having the capability of crawling and walking, at the option of the player, comprising: a body member having an upper and lower portion; a support casing member fixed inside of the upper portion, and having two apertures, one of which is disposed in one side of the support casing member and the other being elongated and in a side opposite the one side; a first pin inside the support casing member and extending through the apertures therein; a gear assembly mounted inside the support casing member; motor means for driving the gear assembly; a shaft connected to the gear assembly; a pair of cranks, one being connected to each end of the shaft; a pair of second pins, one being connected to each crank; a connection member having a pair of arm plates and being fixed inside the lower portion, the length of each arm plate being of such a dimension to enter the inside of the upper portion and to be positioned on the one side and the opposite side thereto of the support casing member, and each arm plate having an elongated aperture at its tip end to engage the pair of second pins, the connecting member pivotally connected to the support casing member by the first pin; a pair of legs connected to the lower portion, each having an upper and lower leg, each leg being articulated to permit the lower leg to pivot relative to the upper leg to simulate the composite action of the lower portion which comprises horizontal and vertical rotation depending on the position of the lower leg; and switch means for activating the motor means.

A mechanical doll toy having the capability of crawling and walking, at the option of the player, comprising: a body member having an upper and lower portion; a support casing member fixed inside of the upper portion, and having two apertures, one of which is disposed in one side of the support casing member and the other being elongated and in a side opposite the one side; a first pin inside the support casing member and extending through the apertures therein; a gear assembly mounted inside the support casing member; motor means for driving the gear assembly; a shaft connected to the gear assembly; a pair of cranks, one being connected to each end of the shaft; a pair of second pins, one being connected to each crank; a connection member having a pair of arm plates and being fixed inside the lower portion, the length of each arm plate being of such a dimension to enter the inside of the upper portion and to be positioned on the one side and the opposite side thereto of the support casing member, and each arm plate having an elongated aperture at its tip end to engage the pair of second pins, the connecting member pivotally connected to the support casing member by the first pin; a pair of legs connected to the lower portion, each having an upper and lower leg, each leg being articulated to permit the lower leg to pivot relative to the upper leg to simulate the composite action of the lower portion which comprises horizontal and vertical rotation depending on the position of the lower leg; and switch means for activating the motor means.
Claim 3
Dependent Claim
47 words
The invention of claim 1 wherein the lower leg portions are each exteriorly convexed on two opposite sides thereof to a degree such that, upon rotating the lower leg portions, the lower leg portions contact the respective upper leg portions before pivoting one hundred and eighty degrees.
Claim 4
Dependent Claim
62 words
The invention of claim 1 wherein that part of each lower leg portion disposed inside each respective upper leg portion is of an outside diameter slightly larger than the inside diameter of that part of the upper leg portion which encloses the lower leg portion so that the upper and lower leg portions do not freely rotate with respect to each other.
Claim 5
Dependent Claim
79 words
The invention of claim 1 further including a pair of simulated arms stationarily fixed to and extending from the upper portion of the body member so that the arms support the body member in approximately a parallel plane to a contact surface while the doll crawls or support the body member in an erect position with the arms extending in approximately a parallel plane to the contact surface while the doll walks with a player or an accessory toy.
Claim 6
Dependent Claim
54 words
The invention of claim 4 further including a pair of simulated hands, one being fixed to the end of each arm and each configured with a surface that slides along the contact surface while the doll crawls, or can be held by the player or attached to an accessory toy while the doll walks.
