Definitions

  • This invention relates generally to walking toys and particularly to an apparatus for simulating the crawling or walking movements of multi-limbed creatures.
  • Crawling or walking toys are generally known and well established in the art. Toys designed to imitate the movement of multi-limbed creatures, especially those with four or more limbs, however, have struggled to provide a realistic and natural simulation of their walk cycles. While there are many examples of two-legged toys that achieve their desired effects with comparatively simple mechanisms, an operative mechanism that imparts realistic and natural limb action in toys with four or more limbs, such as crustaceans, insects, and arthropods, is lacking. Existing mechanisms apply overly complicated designs, or require separate driving force to actuate each individual limb. This is due in part to the increased complexity of motion involved in creatures with four or more limbs, where the relative actions of the additional limbs are staggered.
  • a drive wheel assembly that transfers the rotational force of a drive wheel into synchronized, staggered, linear movement of multiple limbs.
  • Said drive wheel assembly comprises at least a drive wheel and a plurality of shafts configured in an offset and eccentric relation with respect to the main rotational axis of such drive wheel.
  • the joint end of a first limb is coupled to one of these shafts and can freely pivot around said shaft.
  • a second limb is coupled to the same shaft in the same mechanism but in a mirrored or opposite direction.
  • a plurality of limbs can be paired and coupled to the drive wheel assembly in the same mechanism to one or more eccentrically configured shafts.
  • the drive wheel assembly allows the separate pairs of limbs coupled at different eccentrically configured shafts that are offset at different angles to move in a synchronized and partially staggered fashion. It will be seen that as an eccentric shaft is moving towards the highest point in its elliptical operative cycle, it imparts the simulation that the pair of limbs coupled to said shaft are contracting. Conversely, as said shaft is moving towards the lowest point in the elliptical cycle, it imparts the simulation that such limbs are extending.
  • Each limb may further comprise a rotation stop that reciprocally restrains the rotational range of the paired joint ends to impart limitations when joints extend and contract with respect to a body.
  • the rotation stops also ensure that limbs retain their respective orientations when lifted off and then placed backed on to a surface.
  • the tip ends of the limbs extend outwardly and downwardly to make contact with a surface such as a floor or tabletop. The tip ends slide linearly, back and forth on a surface as the limbs are actuated when the drive wheel assembly rolls on a surface. Some of the tip ends may continuously or periodically lift off a surface as the drive wheel assembly rolls on a surface.
  • the limbs cycle through a movement sequence which presents a realistic and natural crawling or walking motion of a multi-limbed creature.
  • Limbs due to being joined at multiple shafts that are offset at different angles and eccentric to the main rotational axis, simulate contraction and extension of limbs.
  • the present invention actuates multi-limb movements without the need for interior power to propel each limb separately.
  • the walking toy disclosed herein is a drive wheel assembly adapted to be propelled along a surface, such as on a floor or tabletop, by pulling or pushing manually. It will be understood by those skilled in the art that, alternative motive power for the propulsion can be provided via other means, such as an electric or battery-powered motor, or a spring-loaded drive mechanism.
  • a frictional element is optionally coupled to the drive wheel assembly to provide frictional engagement with the surface to prevent skidding as the walking creature is propelled across a smooth surface, such as glass or tile.
  • Rough surfaces such as carpets, sandy beaches, and gravel pavements are operable due to the flexibility in the joint ends being freely and pivotally coupled to shafts.
  • walking toy disclosed here is preferably configured in the shape of a crab.
  • the present invention is not limited to any particular six-legged creature. Accordingly, a variety of multi-limbed creatures with more than four limbs may be operated using the present mechanism without departing from the spirit and scope of the present invention.

  • such toy can be shaped to resemble crustaceans, spiders, insects, robots, or aliens.
  • a six-limbed creature is shown as one of the various illustrative embodiments of this invention.

Said limbs are reciprocally movable in either linear direction upon rotating said drive wheel assembly.
  • the force required for moving the various limbs is provided by rotating drive wheel assembly 20 , and thereby actuating the limbs that are coupled to said drive wheel assembly 20 through a plurality of shafts.

It is preferable that each terminal tip end of said limbs contacts a surface, so that it simulates a natural and realistic sense of limbs gripping the surface when a creature is crawling or walking. It will be understood that said tip ends can either continuously or temporarily stay in contact with a surface throughout a rotation cycle.
  • limbs 10 a , 16 a , and 18 a differ in contour and size, but are identical to limbs 18 b , 16 b , and 10 b , respectively. It is preferable to mirror said limbs to impart a realistic and aesthetically pleasing crawling motion of a crab.
