Having Moving Limb Or Foot To Simulate Walking Patents (Class 446/276)
  • Patent number: 6971942
    Abstract: A rotary feedback mechanism includes a first set of electrically conductive pads mounted to a first member and a wiper mounted to a second member. As the first and second members rotate relative to one another, the wiper sequentially contacts one or more pads of the first set of pads and provides an electrical signal to the contacted pad or pads. The electrical signal is communicated via the pad or pads to a controller, providing the controller with an indication of the angular position of the first member relative to the second member.

  • Patent number: 6726523
    Abstract: A remote-controlled toy skateboard device comprises a skateboard with a deck and front and rear truck assemblies pivotally connected to the deck. A toy figure has a lower body portion that is fixedly connected to the deck and an upper body portion that is connected for rotation with respect to the lower body portion. A torso drive mechanism is operably connected to the upper body portion of the toy figure to rotate the upper body portion with respect to the lower body portion. A steering mechanism is operably connected with one of the truck assemblies to tilt the deck with respect to the truck assemblies to thereby steer the skateboard. A drive mechanism is also operably connected to wheels of one truck assembly to propel the skateboard. A remote-control unit is configured to generate signals to remotely control movement of the toy figure, tilt between the deck and truck assemblies, and the speed and travel direction of the skateboard.

  • Patent number: 5501628
    Abstract: A unique, visually enhancing and exciting entertainment system is obtained by providing an elongated path or track, along which a plurality of objects automatically advance, with the objects constructed to perform independent animated movements in direct synchronization with each other. In addition to the coordinated, synchronized, independent movement of each of the objects as the objects movably advance along the track or pathway, the present invention is also constructed to enable each object to perform a separate and unique activity, completely distinguishable from the normal animated movement being performed by the object as the object moves along the path. In this way, further excitement and visual stimulation is provided and an entertainment system is attained which provides long-term benefits and interest to the viewers.

  • Patent number: 4878874
    Abstract: A character includes legs that pivot as well as move up and down relative to the torso either in an alternating, out of phase, walking simulating motion or simultaneously, in phase, to simulate rocking, as selected by the user. Movement of the legs is effected by a reversible motor driving a pair of crank disks that engage the legs connected to the torso by a pin received in a slot. One disk is fixed to the shaft and the other disk is rotatable about the shaft but is engaged by a peg that is received in a semicircular recess in a face of the other disk to, depending on the direction of rotation of the shaft, either drive the other disk in phase with the fixed disk or out of phase with the fixed disk.

  • Patent number: 4824415
    Abstract: A doll with articulated legs and an articulated neck is releasably connected to a motor driven, steerable, remote controlled shopping cart. Movement of the cart causes a cam driven set of handles, to which the doll is attached, to pivot from side-to-side causing the doll to rock from side-to-side alternately lifting one leg and then the other. The accessory has two motors driving separate wheel axles that are each connected through a spring clutch to independently drive the cam. Remote control of the separate motors effects turning of the accessory. As each side of the doll is lifted from the ground, the respective leg is lifted and an eccentric weight within the lifted leg causes the leg to step forwardly.

  • Patent number: 4613315
    Abstract: A doll toy comprising hollow upper and lower body portions. The lower body portions are adapted to wag relative to the upper body portion by a swinging mechanism provided within the upper and lower body portions. The doll toy has a switch provided within a mouth portion and adapted to be actuated by a teething ring or the like for actuating a motor to drive the swinging mechanism. The legs of the doll toy are adapted to be bent around knee portions. With this arrangement, the doll toy can assume a crawling mode and an upright walking mode.

  • Patent number: 4561514
    Abstract: An amusement vehicle has a hollow body shell which is shaped like, for example, a four-footed animal. Front and rear frames are provided inside the body shell, and are coupled to each other by a hollow shaft. The front and rear frames can correlatively rotate in the rolling direction around the hollow shaft. Front wheels are mounted on the front frame, and rear wheels on the rear frame. At least one of these wheels is rotated by a motor. Besides the front and rear wheels, front imitation legs and rear imitation legs are attached to the front and rear frames so as to be swingable in the longitudinal direction of the vehicle. The front and rear imitation legs are reciprocated back and forth by the motor through a power transmission shaft. The power transmission shaft is passed through the hollow shaft.

  • Patent number: 4467555
    Abstract: A doll that may be actuated to simulate a swimming, walking or kicking action includes a torso with a pair of arms rotatably mounted thereto. A head mounting member is pivotally mounted to the upper portion of the torso and a leg mounting structure is secured to the lower portion of the torso. A pair of legs are pivotally mounted on the leg mounting structure in a manner to allow independent rotation. A compound cam is rotatably mounted in the torso and includes a helical groove in which a pair of cam followers are positioned that are in turn secured to each of the legs. A third cam follower is positioned within the torso to engage an eccentric cam that is part of the compound cam. The third cam follower is mechanically connected to the head mounting member resulting in pivoting of the head. A flotation device is arranged to be engageable by the doll's arms for use in the swimming mode.
