<p>Support arms (7, 8) and stop faces (11, 12) are fitted at the interfacing ends of the units to be joined. The arms on the higher units are swung below the stop faces on the lower ones (2), so that the latter are automatically raised to the common coupling height when the units are brought closer together. The support arms may be mounted in funnel-shaped recesses (13, 14) on the ends (5, 6), to swivel about horizontal axes, while the top edge of the recesses can form the stop faces. This makes height adjustment quick and easy.</p> |
