Each wheel (10, 14 / 20, 24) of the wheelchair (1) is fixed to a suspension arm (11,15 / 21, 25). A force transmitting device, for example a spring and damper of the wheelchair unit, directly connects two suspension arms situated on the same side of the wheeled conveyance, so that forces exerted on one of the wheels are transmitted to the other wheel. In this way, obstacles can more conveniently be overcome. A further advantage of the wheelchair is that it can be easily upscaled and driving properties can be adjusted according to a user's preferences.

A drum stick accessory includes a pair of support members defining a parting plane and an elongate channel defined by elongated substantially parallel recesses on opposing sides of the parting plain. Closed resilient loops draw the support members together to minimize the channel cross-sectional dimensions. Restoring forces in the loops tend to revert the support members to the contracted condition. Insertion of a drum stick into the elongate channel separates the members and moves them from the contracted condition to an expanded condition against the action of the loops and the accessory can be reliably frictionally retained on the shaft of the drum stick due to restoring forces urging the support members against the drumstick. Hitting the drum stick as a percussion instrument provides additional sounds produced, for example, by steel shot within compartments formed in the supporting members or jingles attached thereto.

The accessory for a drum stick includes a pair of support members defining a parting plane and an elongate channel defined by elongated substantially parallel arcuate recesses on opposing sides of the parting plain. Biasing members, in the form of closed loops or rings, secure the support members and draw the support members together to minimize the cross-sectional dimensions of the elongate channel when the support members about against each other in a contracted condition. The cross-sectional dimensions of the elongate channel increase when the support members are separated and moved in opposing directions to an expanded condition, resulting in restoring forces in the biasing members that tend to revert the support members to the contracted condition. Sound producing elements are provided, such as steel shot within compartments formed in the supporting members or jingles attached to the support members. Insertion of a drum stick into the elongate channel separates the members and moves them from the contracted condition to an expanded condition against the action of the biasing members and the accessory can be reliably retained on the shaft of the drum stick as a result of frictional forces due to the restoring forces urging the support members against the drumstick. Hitting the drum stick as a percussion instrument provides additional sounds produced by the sound producing members, such as the steel shot or pellets or jingles.
