The workbench is one or more trestle units trestle units having pairs of legs joined to each end of a crosspiece by a hinge unit which allows the legs to fold flat against each other and against the cross-piece of the trestle for storage. The hinge has a stop which allows the legs to be positioned away from each other and away from the crosspiece of the trestle to form a stable trestle unit. A folding brace between pairs of legs further stabilises the trestle. The beams and trestles have holes in their ends, and the beams and the trestles have regularly spaced holes in them. Pegs can be inserted into and through the holes, and they have locking parts on them, allowing them to lock onto the trestle or beam. Pegs can have two latches for attachment to different beams or trestles. Trestles and beams may be thus interconnected to form a supporting framework. |
