  • Patent number: 7997597
    Abstract: An orthopedic mobility scooter for persons with a compromised leg or foot comprising a frame for supporting the weight of an occupant in a sitting position and a leg rest for supporting the compromised leg. The healthy leg is used to propel the scooter with an unobstructed stride. Wheels are located at the front and rear of the frame. Handles attached to a steering column and connected to a front wheel control the direction of travel. A padded seat is positioned near the center of the frame. A horizontal rod extending perpendicular to the frame is used to connect a leg rest and a stabilizing front wheel. The front horizontal rod and rear axle can both be positioned to either side of the frame to accommodate either a left or right compromised leg or foot. The scooter has enough clearance and stability to surmount obstacles such as street curbs.

  • Publication number: 20110031721
    Abstract: The combination scooter/backpack is an article carrying device with the capacity to be converted into a wheeled land vehicle, and therefore has two modes of usage. The article carrying device resembles a conventional backpack with two straps positioned to be placed over the user's shoulders, entitled backpack mode. The wheeled land vehicle functions as a popular collapsible scooter, two wheels mounted upon a board member with propulsion means provided by user's contact with the ground, entitled scooter mode. A horizontal handlebar is positioned at the top of the combination and serves to steer the front wheel during scooter mode. Conversion between backpack mode and scooter mode is accomplished with the raising and lowering of said handlebar and the manipulation of releasable fasteners and latches. In both backpack and scooter modes, a cover circumferentially surrounds the combination scooter/backpack to secure and protect components that are not in use.

  • Patent number: 7882918
    Abstract: An improved electric motor scooter includes: a front frame; a front wheel assembly coupled to the front frame and residing on a surface; a back frame; a back wheel assembly coupled to the back frame and residing on the surface; and a center pivot mechanism coupled to the front frame and the back frame. The center pivot mechanism includes a pivot and a folding axis around which the pivot rotates. The folding axis is not perpendicular to a longitudinal axis of the scooter and is tilted from the longitudinal axis at an angle. A rotation of the pivot in a direction folds the scooter vertically from the surface and moves the back wheel assembly toward the front wheel assembly according to the angle. During the folding, the front wheel assembly and the back wheel assembly each remains on the surface as the pivot rotates.

  • Patent number: 7815215
    Abstract: This disclosure describes a work site utility carrier that configures as a dolly or hand truck in its retracted mode and a work bench in its elevated mode. Pivoting arm pairs enable the carrier's lower and upper receptacles to be transitioned between modes. Two “wheelbarrow” handles are pivotally attached at the lower outer end of the upper receptacle. When oriented at right angles to the upper receptacle bottom, the handles lessen the effort needed to maneuver the carrier. In a “semi-inclined” position the carrier rests in part on the handle outer ends, with much of the mass of the upper receptacle already elevated. Full elevation is facilitated by moving the lower receptacle toward the handle outer ends which act as brakes to keep the carrier stationary during the elevation.

    Abstract: A secondary lock device for a one-hand fold mechanism on a child's stroller is pivotally mounted next to the actuator of the one-hand fold mechanism. The secondary lock device is positioned for convenient access by a finger of the operator to provide an intuitively operable secondary lock device cooperable with the one-hand fold actuator. The secondary lock device is spring-loaded by a torsion spring mounted on the rotational axis of the adjacent cam member forming part of the one-hand fold mechanism. The pivoted lock member includes an outwardly projecting member that engages a corresponding niche in the actuator when in a locking position. The outwardly projecting member rides along a cam surface on the actuator when the actuator is being operated, while the biasing spring returns the outwardly projecting member into the niche when the actuator reaches the home position.
