Abstract
A walking doll having a hollow body on which arms and legs are mounted, the legs being mounted for pivotal movement to effect a walking action, a pneumatically operated assembly being located within said body and interconnected to the legs for producing the pivotal movement thereof, the pneumatically operated assembly including independently operated bellows units that communicate with manually operated members that define the hands of the doll and that are responsive to alternate pressure exerted thereon for producing the walking action of the legs.
Claims14
A walking doll, comprising a hollow body, opposed arms located at the upper portion of said body and a pair of legs located at the lower portion of said body and being mounted for pivotal movement relative thereto, independently air operated pneumatic systems for producing the pivotal movement of said legs, each of said pneumatic systems including a bellows unit located in said body and being expandable in response to the introduction of air therein and an air conduit extending through a said arm interiorly of said body and communicating with a said bellows unit, each of said arms including a hollow member mounted on the outermost end of a said air conduit and defining a hand of said doll, and actuating means interconnecting each leg to said body and being interconnected to said bellows units, so that upon deforming, one of said hollow member, air is injected through its associated air conduit communicating therewith into its associated bellows unit for the expansion thereof, wherein said actuating means effects a corresponding movement of each of said legs in a walking action.
A walking doll, comprising a hollow body on which opposed arms are mounted, a pair of legs mounted on said body at the lowermost end thereof in pivotal relation, means mounted in said body and interconnected to said legs for moving said legs in a pivotal walking motion, and air operated means interconnected to said moving means for effecting the movement thereof for pivotally moving said legs, said air operated means including independently operated pneumatic systems for producing the pivotal movement of said legs, and manually operable means associated with each arm and communicating with a said pneumatic system for effecting the operation thereof for producing the pivotal walking motion of said legs, each of said pneumatic systems including an air responsive bellows and an air conduit communicating therewith for transmitting or removing air therefrom to expand or contract said air responsive bellows, said bellows being mounted in mutual longitudinal alignment and said moving means including an actuator transfer rod that is connected at one end thereof to each of and between said bellows for movement in response to the expansion and contraction thereof, the other end of said actuator transfer rod being pivotally connected to said body so that upon expansion and contraction of said bellows said actuator transfer rod is pivotally movable for effecting a corresponding movement of said legs in a walking action.
A walking doll, comprising a hollow body on which opposed arms ae mounted, a pair of legs mounted on said body at the lowermost end thereof in pivotal relation, means mounted in said body and interconnected to said legs for moving said legs in a pivotal walking motion, and air operated means interconnected to said moving means for effecting the movement thereof for pivotally moving said legs, said air operated means including independently operated pneumatic systems for producing the pivotal movement of said legs, and manually operable means associated with each arm and communicating with a said pneumatic system for effecting the operation thereof for producing the pivotal walking motion of said legs, each of said pneumatic systems including an air responsive member and an air conduit communicating therewith for transmitting or removing air therefrom to expand or contract said air responsive member, each of said air responsive members being defined by a bellows that defines a closed air circuit with a said air conduit communicating therewith, and a hollow hand member joined to the air conduit at the outermost end thereof and defining a hand of the doll, each of said hand members being deformable to inject air through its associated air conduit communicating therewith into its associated bellows for the expansion of the bellows, said bellows being mounted in mutual longitudinal alignment and said moving means including an actuator transfer rod that is connected at one end thereof to each of and between said bellows for movement in response to the expansion and contraction thereof, the other end of said actuator transfer rod being pivotally connected to said body so that upon expansion and contraction of said bellows said actuator transfer rod is pivotally movable for effecting a corresponding movement of said legs in a walking action.
A walking doll, comprising a hollow body on which opposed arms are mounted, a pair of legs mounted on said body at the lowermost end thereof in pivotal relation, means mounted in said body and interconnected to said legs for moving said legs in a pivotal walking motion, and air operated means interconnected to said moving means for effecting the movement thereof for pivotally moving said legs, said air operated means including independently operated pneumatic systems for producing the pivotal movement of said legs, and manually operable means associated with each arm and communicating with a said pneumatic system for effecting the operation thereof for producing the pivotal walking motion of said legs, each of said pneumatic systems including a bellows located in said body and being expandable in response to the introduction of air therein, and an air conduit extending through a said arm and communicating with a said bellows, said manually operable means including a hollow member defining a hand of said doll that communicates with a said air conduit, wherein a squeezing movement of said hand produces a corresponding expansion of the bellows communicating therewith to effect movement of said moving means, said bellows being spaced apart in mutual longitudinal alignment and being connected to each other and to said moving means at a point therebetween, wherein expansion and contraction of said bellows produces a corresponding pivotal movement of said moving means.
A walking doll, comprising a hollow body on which opposed arms are mounted, a pair of legs mounted on said body at the lowermost end thereof in pivotal relation, a pair of air operated bellows mounted interiorly of said body, air conduits, one joined to each bellows and extending through a respective arm, a hollow hand located on the lowermost end of each arm and communicating with an air conduit, each associated bellows, conduit and hand defining a respective closed air system, said bellows being mounted in mutual longitudinal alignment, an actuator rod mounted in said body and connected to both said bellows between said bellows and responsive to movement thereof to effect a pivoting movement, and means interconnecting said actuator rod with the uppermost ends of said legs, wherein pressure alternately exerted on said hollow hands successively compresses and expands said bellows to produce a pivotal movement of said rod and a corresponding alternate pivotal movement of said legs to simulate a walking action thereof.
