Light trolley for e.g. sailboard - has wheel axle sprung relative to frame by rubber blocks in upward direction at forward angle to vertical

摘要

The spring attachment (1) is intended for a light (two-wheeled 9) trolley, e.g. such as used for carrying a sailboard. The connection between the trolley frame (8) and the wheel axle (10) contains at least one resilient block (2) in rubber or the like whose opposite end faces are secured (via plates 3) to the frame (by 4) and the axle respectively. The axis (5) of the block at right angles to these faces is upwardly inclined to the vertical in forward direction such that in use the block is subject to bending load. Without load, this inclination may be 30-60 deg. and is preferably around 45 deg.
