  • Patent number: 10479136
    Abstract: A multiple directional wheel including a wheel frame comprising identical component parts. Each of the wheel frame components comprise: a hub having a main axis about which the multiple directional wheel is adapted to rotate; a hub rim radially surrounding the hub; a first plurality of peripheral roller supporting arms (“first arms”) radially extending from the hub rim and aligned in a first plane; and a second plurality of peripheral roller supporting arms, each member arm of the second plurality of peripheral roller supporting arms having a radially inner base and being circumferentially offset with respect to diagonally adjacent members of the first plurality of peripheral roller supporting arms.

  • Patent number: 9874243
    Abstract: An assembled roller comprising a cylindrical bush having eight external rib surface features and an over-molded roller. The joining edge of the opposing component parts comprises, in axial end profile, a ramp section comprising a ramp surface. The ramp surfaces lie in planes that are parallel or slightly offset by 1° to 20° to the direction or angle of approach of the respective opposed component part immediately prior to engagement, so that the ramp surfaces are adapted to slidingly engage across ramp surfaces in a resistance, rather than snap, fit. This arrangement forms a catch that will hold the component part halves together during an over-molding process as long as the ends of the bush are retarded against axial displacement.
