摘要

The fold-up wedge is made of hard plastics in four parts which hang together on the narrow side so that the two outer parts can be folded so that they can be locked into a wedge. When folded in the other direction they lie flat on one another. A plastics chip designed like a 1 euro coin can be fixed on one of the longer arms. The wedge is preferably about 23 mm thick weighing about 7 g.
