Abstract: Embodiments of the inventive technology relate generally to item support apparatus. Although a focus of the inventive technology may, in some embodiments, be on support of musical related items such as musical instruments, keyboards, and sound speakers, the scope of the inventive technology and its applicability is not necessarily limited as such. In various embodiments, certain inventive technology provides enhanced functionality (e.g., stand adjustability), robust and simplified design (e.g., as may be found in a retention augmented item stand), enhanced performance (as may be found in a telescoping tube lock apparatus), and an ability to more easily control the elevation and lowering of heavy, stand supported items such as speakers.

Abstract: An angle adjustable camber assembly is adapted to support the wheel of a wheelchair having a seat, the rear of which is at a given rear seat height. The assembly comprises a movable member for supporting the wheel. The movable member is adapted to translate and rotate so as to be able to selectively position the wheel at any one of a variety of camber angles while substantially maintaining the rear seat height and a spacing between the top of the wheel and the seat frame.

Abstract: A personal mobility vehicle includes a frame, two or more ground engaging rear wheels connected to the frame and configured to support the frame, and a single ground engaging front wheel connected to the frame and configured to steer the personal mobility vehicle. A drive motor is connected to either the front wheel or the rear wheels, the drive motor being configured to drive the scooter. A steering mechanism is connected to the front wheel and includes a user actuated steering member, the steering mechanism being configured to provide a variable steering ratio, wherein the ratio of the angle of the user actuated steering member from an initial position to the angle of the front wheel from an initial position varies as the user actuated steering member is turned.

Abstract: A personal mobility vehicle has a frame, a ground engaging front wheel connected to the frame and configured to simultaneously drive and steer the personal mobility vehicle, a drive motor connected to the front wheel and configured to drive the front wheel, a steering mechanism connected to the front wheel and configured to steer the front wheel, and a rear suspension including two or more ground engaging rear wheels mounted to support the frame. One or more rear anti-tip wheels are mounted to support the frame. A mechanism for distributing some of the weight of the vehicle away from the rear wheels and onto the rear anti-tip wheels is provided, thereby retarding the unloading of weight from the front wheel.

Abstract: A wheelchair includes a frame, and a front pivot arm pivotally mounted to the frame at a front pivot point, the front pivot arm having a caster for supporting the frame. A rear pivot arm is pivotally mounted to the frame at a rear pivot point, the rear pivot arm having a caster for supporting the frame. A ground engaging mid-wheel drive wheel is connected to the frame. A linkage connects the front and rear pivot arms to each other in a manner such that an upward or downward rotation of one of the pivot arms about its pivot point causes rotation of the other pivot arm about its pivot point in an opposite rotational direction.

Abstract: A wheel mount may generally be comprised of an axle plate and a camber tube clamp that may be height adjustable with respect to the axle plate. The camber tube clamp can be selectively mountable upright or inverted so as to increase an overall range of height adjustability. The camber tube clamp can be mountable in front of or behind the axle plate so as to increase an overall range of center-of-gravity adjustability. The camber tube clamp and the axle plate may have an interlocking feature that may allow the camber tube clamp to slide vertically along the axle plate to facilitate height adjustment. A seat collar can be positioned at various locations along a wheelchair frame for center-of-gravity adjustment. The axle plate can be detached from and attached to the seat tube collar to allow the axle plate and camber tube clamp to be reverse mounted in order to increase the range of center of gravity adjustment.

Abstract: The vehicle comprises a base and a seat moveable along a curve having a focal point. The vehicle is adjustable to position an occupant in the seat to achieve a desired position for the center of gravity of the occupant relative to the focal point of the curve. A method for minimizing effort required to tilt the seat of a personal mobility vehicle comprises the steps of providing a personal mobility vehicle having a seat that is adapted to move along an arc having a center of curvature, positioning the seat substantially horizontally, providing an occupant in the seat, and adjusting the position of the vehicle occupant's center of gravity so that the center of gravity is substantially equal to or below the center of curvature of the arc.

Abstract: An improved wheel assembly comprises a caster swivel post that is adapted to pivot about a pivot axis transverse to the caster swivel post. A caster fork is supported for rotation relative to the caster swivel post and rotatably supports a caster wheel. The caster swivel post is adapted selectively pivot about the pivot axis that is transverse to the caster swivel post or be held in a substantially fixed position. A setscrew can be threadable into an upper end of a pivot nut to hold the pivot nut and thus the caster swivel post in a fixed position within the housing.
