Abstract: A foldable, cross-frame wheelchair with a foldable seat and foldable seatback. The foldable seat has a first outside edge retained relative to a longitudinal frame member at a second, upper end of a first cross-frame member of the wheelchair frame and a second outside edge retained relative to a longitudinal frame member at a second, upper end of a second cross-frame member of the wheelchair frame. A longitudinal hinge portion is interposed between the first and second outside edges to divide the seat into first and second pivotally coupled members. The hinge portion can be disposed to the obverse side of the first and second members of the seat. The foldable seatback can be divided into upper and lower foldable seatbacks.

Abstract: A combined shovel and clearing tool with a shovel and a clearing tool member for being coupled to the shovel. The clearing tool member can be selectively retained in a usage disposition, such as relative to a leading edge of a shovel blade, and in a storage disposition, such as relative to a trailing edge of the shovel blade or relative to a handle of the shovel. The clearing tool member can be retained by, for example, a clip arrangement, an elastic tether, or a rigid arm. Bristles can project from an obverse side of the shovel blade. The handle and the blade can be reconfigurable by, for example, a relative pivoting or a selective coupling of the handle with multiple receiving portions on the blade. A universal clearing tool can be coupled to a standard shovel.

Abstract: An occupant-propelled vehicle comprising a vehicle frame, a vehicle propulsion system with a movable force receiver, and a vehicle steering arrangement in one embodiment comprising a tilt-grip steering post, a steering drum, a steered wheel, a steered drum, and a flexible, sheathed cable. An inner member of the cable overlies the steered drum and the steering drum whereby a pivoting of the tilt-grip steering post induces a steering of the steered wheel. The steering post may have an axis of rotation perpendicular to its longitudinal axis and tangent to an arc of rotation of the moveable force receiver. The diameters of the steered and steering drums may be varied, and the steered drum may be disengagably indexed to the steered wheel. The steered wheel may be coupled to a second wheel to steer the second wheel in response to a steering of the steered wheel.

Abstract: An occupant-propelled vehicle comprising a vehicle body and a first vehicle propulsion system that comprises a first drive wheel, a drum rotatably coupled to the vehicle frame and drivingly engaged with the drive wheel, a movable force receiver, an elongated and flexible motion conversion member drivably coupled with the force receiver with a first reference point spaced a given effective-travel distance from a second reference point and a body portion overlying the drum, and an actuator mechanism for actuating the motion conversion member between a slackened, disengaged state and a tensioned state wherein there is frictional engagement between the drum and the motion conversion member. The actuator mechanism may be automatic or manual.
