Abstract: A workbench comprises a worktop supported by a collapsible leg arrangement, the worktop being adapted to support a vice comprising separate fixed and movable vice jaws. The worktop is formed with elongated slots at predetermined locations each adapted to receive a depending hook-like formation of a fixed vice jaw. The worktop also is formed at predetermined locations at its edge and extending inboard of the latter elongate recesses into each of which movable vice jaws can be located and secured by complementary formations at the inboard ends of the recesses and movable vice jaws. The separate fixed and movable vice jaws are secured in an operational working relationship by the worktop and such relationship can be varied.

Abstract: Personnel elevating apparatus comprises a support platform supportable above ground level on leg frames pivoted to the platform. Side guard rails extend upwardly therefrom in an erected position. An end support or hand rail is pivotally connected to each other and to the support platform. The support platform, leg frames, guard rails and support or hand rail are foldable into relatively flat condition. Pivoted to the leg frame at the support or hand rail end of the support platform a link rod is engageable with the other leg frame to serve as a leg strut, or with one of the guard rails to permit collapse or erection of the apparatus.
