A freestanding self-righting frame
A freestanding self-righting frame 1 has a ground engaging base 2 which may be formed by a pair of ground engaging wheels 3. An upstanding frame 4 is pivotally mounted on the base by pivot mounts 5, 6 for pivotal movement about a substantially horizontal axis A. The frame may also pivot on the wheels forming the base. A counterweight 9 is mounted on the frame below the pivot axis. The counterweight retains the frame in a normal, upright operating position and will resist pivotal movement of the frame on the wheels away from the upright normal operating position. The frame may be portable and/or mobile. The wheels may be connected to the frame by a swivel mount 22 and may include a releasable locking means. The frame may include a pair of upright stanchions 15 and a plurality of rail members 16 between them.
