Abstract:
A vehicle includes a forward frame portion, a rear frame portion, and a motion control system that movably interconnects the forward frame portion and the rear frame portion. A forward acceleration of the rear frame portion resulting from a driving force imparted by a wheel supported by the rear frame portion imparts a first force onto the motion control system that counters a second force imparted on the motion control system by an acceleration of a payload supported by the forward frame portion as a result of the forward acceleration.

Embodiments include a suspension or travel in at least one of the upper vehicle (rear and/or front), middle vehicle (rear and/or front), or below vehicle (rear and/or front). Various embodiments included a combination thereof.
Abstract:
A vehicle, comprising: a forward frame portion; a rear frame portion; and a motion control system comprising a first motion control device that movably interconnects the forward frame portion and the rear frame portion and a second motion control device that movably interconnects the forward frame portion and the rear frame portion, wherein the first motion control device connects to the rear frame portion at a first location, and the second motion control device connects to the rear frame portion at a second location that is a fixed distance from the first location, and the motion control system, by virtue of a geometric arrangement of the motion control system relative to the forward frame portion and the rear frame portion, adopts, in response to a forward acceleration of the rear frame portion resulting from a driving force imparted by a wheel supported by the rear frame portion, an operating state in which forces imparted onto the motion control system by a tensioning of a drivetrain element that transfers driving energy from a driving axle supported by the forward frame portion to a driven axle supported by the rear frame portion, the forward acceleration of the rear frame portion, and an acceleration of a user mass supported by the forward frame portion are in equilibrium.
Abstract:
A vehicle component, comprising a first arm, a second arm, and a yoke portion that connects the first arm and the second arm, wherein at least one of the first arm, the second arm and the yoke portion comprises a tubular structure and an interior wall that divides the tubular structure into a first tubular chamber and a second tubular chamber,
Abstract:
A tensioning device for bicycle front and rear wheel assemblies. A skewer assembly with a thumbnut is securable to the wheel assembly with a quick-release assembly. Portions of the skewer assembly are removable from the quick-release assembly by turning the thumbnut a partial turn, such as a quarter of a turn. Removal of the skewer assembly allows the front wheel to be removed. In another embodiment, the skewer assembly is able to be removed by turning the quick-release assembly by a partial turn, such as a quarter of a turn.
Abstract:
A lightweight, high strength bicycle seat post for securing a bicycle seat to a seat tube of a bicycle frame. It comprises a hollow metal tubular member having a seat tube portion for reception in and securement to the seat tube of a bicycle frame, and an integral head portion comprised of four planar walls diverging in an upward direction to form an open space. A pair of the sidewalls are oriented in a fore and aft direction to the fore and aft direction of the bicycle seat and a pair of end walls which are transverse to the fore and aft direction and connects the fore and aft ends of the pair of sidewalls together defining the open space, which, preferably, is generally rectangular. The upper edges of the sidewalls have arcuate load reacting edges, which define a seat angle adjustment path, and a clamp assembly secures the bicycle seat to the load reacting edges so that the seat loads are transferred directly to the load reacting edges at any seat angle. In a preferred embodiment, the integral head portion is formed by a metal swaging process from an extruded metal tube and the metal tube is selected from steel, aluminum, or titanium alloy. The arcuate load reacting edges of the sidewalls can include a lip which is normal to the load reacting edges, and the clamp parts include washer members which have arcuate grooves for receiving the lip.
Abstract:
This invention relates to front fork, telescoping type suspension systems for bicycles. The main focus of the invention is the brake bridge assembly, the fork crown assembly and the joinder of these assemblies to form the fork suspension. The brake bridge assembly serves two main functions: 1) it provides a stiff structural connection between the right and left telescoping struts, to reduce wheel wobble during high speed wheel impacts, and 2) it provides a structural support for the brake cable stop. The invention provides for increased stiffness and lower stresses in the brake bridge, which translates into improved directional stability for the front wheel, less displacement for the brake cable stop .(when the brake loads are applied) and improved fatigue life for the assembly. It also provides for a simpler and less expensive means for mounting the brake bridge to the fork assembly. The invention also encompasses the fork crown producing a lightweight structure with high torsional and bending rigidity. The connections of the stanchions to the crown are achieved through a variety of methods including, (a) interference fit and bonding, (b) collet assembly and (c) "pinch-bolt" connections.
Abstract:
A lightweight handlebar/steerer locking mechanism for use on road and mountain bicycles. The invention provides higher fatigue and impact resistance, lower material and production costs, and improved adjustability, compared to prior art designs, all at a reduced weight.The superior structural performance of the invention is provided by a unique, 3-dimensional, sliding, compression wedge. The 3-dimension wedge improves the stress distributions within the device my introducing a more uniform wedging (locking) action on the circumference of the steerer tube. This allows the mating parts to be designed lighter, thereby reducing the total weight of the assembly. The configuration of the design also lends itself to modern metal working methods. This further improves the strength of the parts by increasing the material allowables. Also, these metal working operations help to reduce material scrap, thus reducing material costs.The invention improves the adjustability of the handle-bar assembly by allowing the locking and un-locking function to be accomplished by hand, without any assistance from a special tool. The locking function is activated and de-activated by the twisting of a tightening cap. This can be done by hand, from the sitting position of the bicycle rider.
Abstract:
There is disclosed a uniquely shaped bicycle chainstay structure produced using modern metal working methods, without the use of welding. The uniqueness of the structure allows a significant shortening of the chainstay length while increasing the tire and chain-ring clearances. An accomplishment not possible using prior art methods.
Abstract:
A vehicle component that can include a suspension system for bicycles, electric bicycles, or electric scooters. The vehicle component can include a sliding four-bar system with a link pivotally connecting a swing arm to the front triangle and a sliding link slidably connecting the swing arm to a front triangle bottom portion. The resulting suspension system can be optimized to balance forces of generate a balance of forces between of drive and driven loads against the mass of the rider and inertia while still free for the rear wheel to trace the ground.
