  • Patent number: 8672336
    Abstract: The automatic scooter unlocking mechanism is an improvement to existing folding kick scooter designs whereby vertical movement of a telescoping handlebar automatically causes rotation, and a corresponding unlocking, of a scooter footboard latch. The inventive mechanism places an extension on to the rotating handle of the footboard latch and places the distal end of the extension in such a location so as to contact a protuberance located on the sliding portion of the telescoping handlebar. During contact, the extension is deflected and the handle of the footboard latch rotates and unlocks, allowing for free rotation of the scooter footboard between folded and unfolded states. The inventive mechanism can be integral to a kick scooter design or can take the form of a system that can be installed on to a pre-existing kick scooter in an aftermarket fashion.

  • Publication number: 20130056944
    Abstract: A magnetic braking, governing, or speed retarding system for use with a wheeled conveyance may take advantage of eddy currents induced when a magnet moves past a non-magnetic conductor. A plurality of magnets may be disposed within a rotor that rotates as a wheel axle rotates. The magnets rotate past one or more relatively stationary stators to generate eddy currents that create a resistance on the rotor, thereby acting to retard or slow the rotational speed of the rotor and the axle. The system may be particularly well-suited with a wheeled conveyance such as a sled that is gravity driven and travels downhill along a track. The speed governing system may apply lesser force in relatively flat sections of the track, due to slower wheel rotational speeds, and greater force as the conveyance attempts to pick up speed, e.g., in steeper sections.

  • Patent number: 8262114
    Abstract: A tool-less coupling of a child vehicle having a front frame and a rear frame includes a post coupled to one of the front or rear frames; a locking insert having at least one flexible table coupled to the post, and a head tube coupled to the other of the front or rear frame, wherein an opening in a first end of the head tube is sized to cause inward flexing of the flexible tab as the post is inserted through the head tube, and the flexible tab flexes back outwardly after passing through the opening in the head tube so that a portion of the flexible tab is adjacent an end surface of the head tube such that the flexible tab cannot move back through the opening. Accordingly, the removal of the post from the head tube is prohibited and the front and rear frames are coupled together. A method for a tool-less assembly of a child vehicle is also disclosed.

  • Publication number: 20120217721
    Abstract: A bidirectional propulsion caster assembly is disclosed for enabling a rider to generate bi-directional motion from a ride-on device. A mounting bracket is attachable to the bottom of the device and defines a pivot axis extending in a generally transverse direction across the bottom of the device. A rocker bracket and caster shaft having a caster shaft axis are attached to the mounting bracket and pivot about the pivot axis along an arc between first and second positions. A wheel bracket is mounted to and rotates about the caster shaft. A wheel is mounted to the wheel bracket for rotation about a wheel axis angularly offset from the caster shaft axis. One or more changeable pivot stops may be attached to the rocker bracket or the mounting bracket and effective to further define the available arc of rotation.

  • Patent number: 8205895
    Abstract: A swingable and speedable freewheeled vehicle includes a swingable device installed between a frame and each rear wheel. The swingable device has a guiding track fixed to a seated member, a spindle pivoted on said seated member, and a sliding assembly for sliding along the guiding track. Thereby, while driving the freewheeled vehicle via swinging, a sliding stem of the sliding assembly would slide along the guiding track and subject to an inertial force. Accordingly, a distance between the ground and the frame would be varied commensurately with the freewheeled vehicle moving along with the inertia force during the sliding so as to readily and speedily motivate the freewheeled vehicle forwards.

  • Patent number: 8191909
    Abstract: A patient support platform or mobile support cart is provided. The mobile support cart includes a transmission system that allows the patient and/or medical staff member to choose a stop, walk or roll mode. In the stop mode, the castor wheels are prevented from rolling across the floor by a braking mechanism. In the walking mode, the transmission causes a tracking wheel to engage the floor for providing tracked or guided motion to the mobile support cart. In a roll mode, the tracking wheel is raised and is disengaged from the floor, and the castor wheels are free to rotate. The platform is capable of supporting devices that may be attached or associated with a patient throughout their stay at a healthcare facility. The braking mechanism can include a cable and an associated brake arm, with the cable positioned to allow braking without inhibiting the ability of the castor wheel to swivel with respect to a castor mounting plate.
