Abstract: A load resisting device for use in an exercise machine which includes a cylinder, a piston which is movable in a first direction inside the cylinder against a force generated by air pressure in the cylinder, and an O-ring seal, mounted to the piston, which provides a seal between the piston and the cylinder, when the piston is moved in a first direction, and which allows air to bypass the O-ring when the piston is moved in a second direction which is opposite to the first direction.

Abstract: A resistance device for an exercise machine which includes a flywheel which is mounted for rotation about an axis and two actuators, on opposed sides of the flywheel, which are mounted for rotation in unison about the axis and which are directly coupled to the flywheel.

Abstract: An exercise machine which includes an elongate frame which forms an enclosure, a resistance assembly located at least partly in the enclosure, a support member for supporting the frame at an inclined position with an upwardly facing front side and a downwardly facing rear side, a seat extending from the front side of the frame at a location at which part of the frame opposes a back of a user seated on the seat, and at least a first actuator which is movable by the user against a first resistance force which is generated by the resistance assembly.

Abstract: A scooter drive arrangement which includes a first shaft, with a one-way bearing and a clutch, which is connected to a driven wheel, and a second shaft, which is rotated by an engine, through a centrifugal clutch, which has two fixed pulleys which respectively drive the clutch and the one-way bearing, through belts.

Abstract: An expansion pipe for an engine which has a curved tubular body, a first connector for connecting an interior of the body to an exhaust part of the engine, and a second connector which is used for connecting an interior of the body to an exhaust gas treatment device and which has the same configuration as the first connector.

Abstract: A support assembly for a ground-engaging component of a vehicle which includes a base section, a column which is mounted for movement relative to the base section between a traveling position and a storage position, and a locking assembly for holding the column. The locking assembly is capable of locking the column in the traveling position or in a storage position. The assembly also includes an actuator which, when the column is in the traveling position, is movable from a rest position along a release path to initiate a release of the locking assembly, and thereby allow the column to be moved from the traveling position to the storage position.

Abstract: An exercise machine which includes an elongate frame which forms an enclosure, a resistance assembly located at least partly in the enclosure, a support member for supporting the frame at an inclined position with an upwardly facing front side and a downwardly facing rear side, a seat extending from the front side of the frame at a location at which part of the frame opposes a back of a user seated on the seat, and at least a first actuator which is movable by the user against a first resistance force which is generated by the resistance assembly.

Abstract: A resistance assembly for use in an exercise machine which includes a cylinder and a piston with a hollow piston rod which is slidably engaged with the cylinder. The interiors of the cylinder and the piston rod are pressurised using a compressor to provide a controllable resistance force against which a user can exercise.

Abstract: A water vehicle includes at least first and second foils which are at least partially submersible in water. These foils are movable, at least to a limited extent relative to each other. Repeated movement of the foils generates a propelling force that will move the water vehicle on the body of water.
