Title: Ironing board cover with turned-in seam contg. tensioning cord - whose ends extend through element with one-way clamp action
IPC: D06F81/14
Filed: 1982-03-08
Abstract: The cover for an ironing board comprises a strip of material with a turned-in seam extending along one short and the two long edges through which a tensioning cord is passed whose ends project from the seam at the other short edge. These ends extend through a clamp unit and can be freely moved through this unit in the tensioning direction but are retained therein by the tension force acting in opposite direction. The unit may diverge conically from an insert opening at one end to an opening at the other end whilst a clamping element, e.g. a knurled disc, is longitudinally slidable between the diverging side walls.
