Large shelf for glass or plastics sheets

摘要

The large shelf has a main frame (1) in which the shelf elements (6) slide and can be drawn out or pushed back. There is a servo motor to do this. On the frame and preferably beneath the shelf elements at the front and back is a shaft (10,11) with an endless belt (or chain or cable) running between the two. One of the shafts is driven by the motor. Each shelf element can be locked positively to the belt, etc, by a coupling device. This is activated by a handle(28) at the front for each element.
