20080258426 | Bicycle - A bicycle comprising a longitudinally extending frame, a front wheel for steering disposed at the front of the frame, a rear wheel disposed at the rear thereof, and auxiliary wheels for assisting the traveling of the bicycle. The bicycle further comprises an auxiliary wheels for assisting the traveling of the bicycle. The bicycle further comprises an auxiliary means having first and second auxiliary supporting devices disposed on one side and the other side of the rear wheel. Each of the auxiliary supporting devices includes an arm having one end pivotally supported on the frame and the other free end movable in the vertical direction, an auxiliary wheel pivotally supported parallel with the rear wheel, an energizing means for energizing the arm in the rotating direction the auxiliary wheel moves downward, and an arm lock means securing the arm. The pair of arms can be rotated independently of each other, and the arm lock means can restrain the rotation of the arms and fix the vertical movement of the auxiliary wheels by their operation. | 10-23-2008 |
20090108559 | Riding apparatus for disabled persons and kit for making same - A tricycle adapted for use by children with autistic spectral disorder. A tricycle with toe clips, hand grips, seat belt, and adjustable handlebars and seat adapted for use by a child with autistic spectrum disorder. A tricycle with other distracting items to help lure use by a child with autistic spectrum disorder.

20090289437 | VEHICLE WITH THREE WHEELS - The frame of the vehicle, which is capable of inclining in curves and preferably comprises a front wheel and two rear wheels, is rotatably mounted to a steering head beneath the driver's seat. Rigid driving elements are arranged in the area of this steering head, which couple the inclination of the vehicle frame to the opposite movements of the rear wheel swing arms by means of control elements in order to control the vehicle inclination and steer the rear wheels. In order to support the initial horizontal position of the tricycle, return springs are provided at the steering head, which force the rear wheel swing arms into a balanced mid-position. In slow vehicles suitable for rehabilitation purposes, the steering head beneath the driver's seat may be blocked by a brake in the starting phase. In faster vehicles, the movement of the rear wheel swing arms may be assisted by foot levers or manually operated hydraulic cylinders. | 11-26-2009 |
20110018225 | DUAL RIDING AND DRIVING TRICYCLE IN JUXTAPOSING LINK - A dual riding and driving tricycle in juxtaposing link comprises a primary bicycle body, an auxiliary cycle body and an articulation mechanism including a resilient tension mechanism. | 01-27-2011 |
20110018226 | PIVOT MECHANISM FOR SCOOTERS, TRICYCLES AND THE LIKE - A pivot mechanism includes a base member configured to be coupled to a first element and a generally cylindrical rotating member configured to be coupled to a second element. An elongate pin extends through the base member and rotating member and defines a pivot axis. The rotating member is capable of rotating relative to the base member about the pivot axis. The elongate pin is movable in a direction generally parallel to the pivot axis between a secured position and a release position. In the secured position, the rotating member is prevented from rotating relative to the base member, and in the release position, the rotating member is permitted to rotate relative to the base member. The pivot mechanism may be incorporated into a scooter or a tricycle to provide different configurations thereof. | 01-27-2011 |
20110074131 | Rear Wheels Mounting Structure of Motorized Tricycle - A motorized tricycle comprising a frame including first, second, and third coupling members, two rear wheels, and a rear wheels mounting structure comprising side pieces on either side; cross pieces interconnecting the side pieces; two forward cylindrical first joints; two seats each projecting upward from the topmost side piece and comprising a top second joint and a bottom first threaded hole; two second threaded holes each disposed on a section between the first and second joints of the same side; two inverted L-shaped reinforcement plates comprising a hollow boss projecting inward from a bending point, and first and second through holes at both ends respectively; two sleeves each put on the first joint; two cylinders each disposed in the second joint; and screws for securing the reinforcement plate, the rear wheels mounting structure, and the frame together. | 03-31-2011 |
20110193315 | Tricycle With Canopy - The present invention relates to a tricycle having one front wheel and two rear wheels, the tricycle including: a seat frame mounted on a support frame to which the rear wheels are coupled, and having a concave seat formed at the front center thereof; side plates and a rear plate fixed at the bottom ends thereof to the both sides and the rear side of the seat frame; a plurality of space bars disposed spaced apart from each other between the side plates formed on the both sides of the seat frame; and a canopy mounted supportedly onto the plurality of space bars disposed between the side plates. | 08-11-2011 |
20120043737 | SPIN-OUT RIDING TOY - A riding toy provides a spin-out feature. The riding toy includes a frame, a steerable front wheel mounted to the frame and a rear wheel mounted to the frame. A rear carriage is pivotally attached to the frame so as to pivot about a generally horizontal axis. A caster is mounted to the rear carriage so as to pivot about a generally vertical axis. A lever is pivotally attached to the frame. A link has a leading end pivotally connected to the lever and a trailing end pivotally connected to the rear carriage. As a result, the riding toy may be changed from a traditional configuration, where the rear wheel of the riding toy contacts a riding surface upon which the riding toy is being ridden, to a spin-out configuration, where the caster lifts the rear wheel of the riding toy off of the riding surface, by pulling the lever. | 02-23-2012 |
20120056400 | TRICYCLE CONVERSION ASSEMBLY FOR A MOTORCYCLE - A tricycle conversion assembly for a motorcycle comprising two bilaterally symmetrical stabilizers independently mounted to and suspended from a motorcycle frame by adjustable means of attachment. The stabilizers dispose auxiliary wheels essentially even with and parallel to the motorcycle rear wheel wherein the adjustable means of attachment suspend the stabilizers from the motorcycle without moving parts and provide for modifying the alignment of the stabilizers with the motorcycle and for modifying the reactivity of the stabilizers with variations in the ground surface. The assembly provides the opportunity to replace a stabilizer with a side car, and for attachment of an optional towing crossbar at the rear of the assembly. | 03-08-2012 |
20120261896 | MODULAR TRAILING EDGE FOR BICYCLE STEM - A bicycle including a front wheel, a rear wheel, and a frame supported on the front and rear wheels, the frame having a frame member. The bicycle further includes a first fairing member protruding outward from the frame member and having a side surface defining an aerodynamic trailing edge and a second fairing member detachably mounted on the first fairing member such that the side surface is exposed. | 10-18-2012 |
20150021877 | BICYCLE FRAME AND BICYCLE, AND BABY CARRIAGE USING SAME CAPABLE OF TWO-WHEEL AND THREE-WHEEL CONVERSION - A cycle frame easily converted from a bicycle to a tricycle and vice versa, and to a cycle and a baby carriage using same. The cycle includes a main frame including a main support and a pair of sub-supports branching from the main support, a pair of conversion frames, front end portions thereof being hingeably connected to rear end portions of the sub-supports such that the distance between rear end portions thereof is adjustable, a pair of connection brackets respectively connected to the rear end portions of the conversion frames, a fork frame rotatably connected to the front end portion of the main support, a front wheel shaft rotatably connected to the fork frame, a main rear wheel shaft, both ends thereof being respectively and separably connected to the connection brackets, and a propelling pedal rotatably mounted on the main support and drive-connected to the main rear wheel shaft. | 01-22-2015 |
