Abstract

Abstract A walking doll of the type in which its legs are operatively connected with its torso and are arranged to step forward alternately as the weight is shifted from one leg to the other by swinging its torso right and left, including a pneumatic system operative for imparting the swinging motion to the torso. The pneumatic system comprises a hollow inflatable body disposed within the torso and a pneumatic remote-control device for supplying and removing air from the inflatable body. Pneumatic accessories such as a ballon, a sounder, or a toy dog may be attached to the doll. The body may be moved and caused to ''''bark'''' by pneumatic means.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 233 words
A pneumatically operable walking doll comprising a hollow torso having a front side, a rear side, a right side and a left side, a head mounted on said torso, and a pair of legs one attached on the right side and the other attached on the left side of said torso, an operating framework located within said hollow torso, means pivotally mounting said framework within said torso for pivotal movement in a pLane extending through the right and left sides of said torso, means for connecting said legs to said framework for effecting movement of said legs in the direction of the front side of said torso relative to the pivotal movement of said framework, a pneumatic system including an inflatable hollow body positioned within said torso and secured at one end to said framework and at its other end to said torso and a manually operable air pump means located exteriorly of said torso and connected to said hollow body, said hollow body, when it is inflated, increasing its dimension between its attachment to said framework and said torso for pivoted said framework toward one of the right and left sides thereof, a tension spring connected at one end to the interior of said torso and at its other end to said framework and biasing said framework in the direction opposite to which it is pivoted when said hollow body is inflated.
Claim 2
Dependent Claim 233 words
A pneumatically operable walking doll comprising a hollow torso having a front side, a rear side, a right side and a left side, a head mounted on said torso, and a pair of legs one attached on the right side and the other attached on the left side of said torso, an operating framework located within said hollow torso, means pivotally mounting said framework within said torso for pivotal movement in a pLane extending through the right and left sides of said torso, means for connecting said legs to said framework for effecting movement of said legs in the direction of the front side of said torso relative to the pivotal movement of said framework, a pneumatic system including an inflatable hollow body positioned within said torso and secured at one end to said framework and at its other end to said torso and a manually operable air pump means located exteriorly of said torso and connected to said hollow body, said hollow body, when it is inflated, increasing its dimension between its attachment to said framework and said torso for pivoted said framework toward one of the right and left sides thereof, a tension spring connected at one end to the interior of said torso and at its other end to said framework and biasing said framework in the direction opposite to which it is pivoted when said hollow body is inflated.
Claim 3
Dependent Claim 82 words
A pneumatically operable walking doll, as set forth in claim 1, wherein said inflatable hollow body is a bellows and expands in the direction extending between the right and left sides of said torso, a supporting plate connected to one of the rear and front sides of said torso within its interior and extending inwardly from the side to which it is attached, and said bellows connected at one end to said supporting plate and at its other end to said framework.
Claim 4
Dependent Claim 117 words
A pneumatically operable walking doll, as set forth in claim 1, wherein means are arranged for limiting pivotal movement of said framework relative to said torso, said means for limiting pivotal movement of said framework including an upwardly extending first lug forming a part of said framework, said lug having a cut-out in its lower end, a second lug secured to the interior of the lower end of said torso and extending upwardly into the cut-out in said first lug, said tension spring secured to said first lug so that said second lug is normally kept in abutting engagement with one side edge of the cut-out in said first lug by the action of said tension spring.
