Variable-length framework for bearing coverings, in particular sheeting-type coverings

摘要

The invention relates to a variable-length framework for bearing coverings, in particular sheeting-type coverings. Said framework comprises interacting arcuate rods and is characterised in that it is composed of at least two pairs of rods, the respective arcuate rods which form a pair being rotatably fixed at their intersecting vertices, and the feet of two adjacent arcuate rod pairs being rotatably fixed against one another in each case. <IMAGE>
