ABSTRACT:
A telescopic brace assembly for supporting a work surface 1 which can be folded relative to a frame structure 5 includes two tubes 6,7 which are capable of being moved telescopically, one within the other, and the mutually opposite free ends of which are intended to be pivotally connected to a respective one of the objects. Arranged within the telescopic tubes is a spring 14 which biases the tubes together. The brace assembly further includes a locking arm 8 for releasably locking the tubes in a working position. The spring is arranged to be compressed as the tubes are extended one from the other, while storing energy. The extent to which the tubes can be withdrawn one from the other is determined by the extent to which the spring can be compressed.
