Abstract: A street paddle which permits a user of an associated skateboard of similar devise to smoothly stroke with two hands and arms and upper body, rather than using their foot to accelerate or decelerate is disclosed. The street paddle is unique in that is allows a skateboard rider to pull and push their way on the street to accelerate, similar to a stand up paddlers or canoe paddlers on the water. A contact point, blade footing of the street paddle, where the paddle device comes in contact with the ground, connects to the bottom of an elongated shaft of the paddle. The footing comprises form and material that facilitates traction, when applied against a traveled surface, as well as shock dampening action to assist in smoothness and acceleration. As such, the street paddle may also be used to decelerate the speed by dragging the footing on the ground in such a way that the friction of the contact slows the skateboard.

Abstract: A method and apparatus suitable for stabilizing a two-wheeled motorcycle during operation. The apparatus is securable to a location near the front of the motorcycle engine. At least one arm assembly extends in a rearward direction relative to the motorcycle and outboard of the motorcycle's engine and operator's seat. A wheel assembly is mounted at an rearward end of the arm assembly and includes a wheel engageable with a surface supporting the motorcycle. A biasing assembly biases the arm assembly to rotate upward an adjustable limited distance at which the wheel is not engaged with the support surface. The biasing assembly applies a biasing resistance to downward rotation of the arm assembly over the limited distance for engaging the wheel with the support surface, yet allows the arm assembly to rotate upward farther than the limited distance to a raised position.

A portion of the vehicle cover extends between the upper wall of the fuel tank and the lower surface of the seat and includes an upright portion extending between an upper wall of the fuel tank and the lower surface of the seat. The vehicle protects the at least one connector of the fuel pump without causing an increase in the number of components and manufacturing steps.

Abstract: A street paddle which permits a rider of an associated skateboard or similar device to smoothly stroke and accelerate down the street using one's arms, hand and upper body, rather than using their foot to accelerate is disclosed. The street paddle is unique in that it allows a skateboard rider to pull and push their way on the street to accelerate, similar to an oarsman on the water, or a skier on snow, yet on the ground. A contact point, or footing, of the street paddle, where the paddle device comes in contact with the ground, connects to the bottom of an elongated shaft of the paddle. The footing comprises form and material that facilitates traction, when applied against a traveled surface, as well as shock dampening action to assist in smoothness and acceleration. As such the street paddle may also be used to decelerate the speed by dragging the footing on the ground in such a way that the friction of the contact slows the skateboard.

Vertically extending bolts pass through the horizontally extending flanges and are held by slugs located in rail supports of the rear subframe of the motorcycle.

Abstract: Poles and fastenings for biking upright allow enabling of the effort of an additional upright cyclist on practically any operator-powered vehicle. Those poles consist of a bar with a handle and a support below. The bar can be resilient and the support may have a pear-shaped form, or it may look as a spike. The support may also contain a roller with an overrunning clutch (or without it). The poles' bars can be interconnected by a crossbar, which can be fixed on the skeleton of the vehicle near the rear wheel with the possibility of sliding in the location clutches. The poles in the cyclist's hands can lean on the road surface or on fasteners provided in a special devices set for biking upright. The fasteners for the legs of upright cyclist contain stationary pedals. The body movements of the upright cyclist are similar to the body movements of a skier.

Abstract: A fuel valve is provided in the Diesel fuel supply line to a cylinder to be deactivated. A return fuel line is provided and when the fuel valve is closed the fuel is returned to the fuel supply tank. In open position fuel is directed to the top portion of the cylinder. The cylinder is provided with a conventional exhaust valve. However, the intake valve is modified to be located closer to the top of the cylinder. The previous gap of about ¼ inch is reduced to about 0.005 to 0.015 inches. This allows the intake valve to remain open instead of closed as the piston moves upwardly in a deactivated cylinder when the exhaust valve is closed, to allow air to enter the intake valve in the full up position of the piston. This valve system e located in all Diesel engines including Diesel powered motocycles.

A lattice body of synthetic resin is formed by reducing the thickness of a plurality of plate ribs gradually from the proximal ends to the distal ends and disposing the plate ribs intersecting with each other. The lattice bodies are arranged in a stack such that the direction of the plate ribs extending from the proximal ends toward the distal ends is oriented along the fore-and-aft direction of the two-wheeled vehicle. The shock absorber is mountable at the front end of the two-wheeled vehicle.

Abstract: A foot-operated propulsion apparatus for a wheelchair and/or other selected devices such as desk chairs and furniture. In one embodiment, the apparatus includes a support structure coupled to the selected device and having at least one roller aperture. A roller element having a circular cross-sectional shape is received in the roller aperture and is rotatable relative to the support structure about a rotation axis or a plurality of rotation axes. The roller element has a first external portion projecting upwardly from the aperture to engage the user's foot and a second external surface portion projecting downwardly through the aperture to engage the ground or other support surface. As the user engages the roller element and rotates the element by foot, the propulsion apparatus and the device to which it is coupled move along the ground. The user can directly engage the roller element or can engage a brake device coupled to the roller element to slow the propulsion device.

Abstract: A trolley supports a person on a platform (1) and moves as a result of his changing weight distribution so that he can conveniently perform tasks above his normal reach. The platform (1) is supported on springs (2) on a frame (3) with castor wheels (4). Rods (6) are suspended from the platform at an angle, extend to the ground and are arranged so that when one side of the platform is depressed a rod engages the ground and moves the trolley in that direction. By changing his weight distribution the person on the platform causes other rods to brake or drive the trolley in other directions.

The horse has two curved pitching rods, two movable support rods, and two rider controllable L-shaped levers with pedals. By manipulating the pedals, the rider can rock back and forth on the same spot, move the horse forward, or change the horse's moving direction.

Abstract: A motorcycle in which the forward nose-diving during braking is to be prevented. For that purpose, the motorcycle includes a spring-damping system which acts upon a pressure gas space; the pressure gas space is supplied during the braking operation with compressed gas from a pressure reservoir, by way of a control valve. The pressure which builds up in the gas pressure space thereby acts opposite the nose-diving of the motorcycle.
