Title: Protective sliding runners for school furniture - HAS RIBBED CONTACT FACE FOR SLIDING WITHOUT FRICTION THROUGH DIRT NOT OVER IT
Inventor: SCHAFFITZEL HERMANN
IPC: A47B91/06
Filed: 1974-10-24
Abstract: The protective sliding runners for school tables and chairs are provided with a support face which has several spaced ribs (3, 4, 5) running side by side in the same direction so that hollow recesses (1, 2) are formed. In this way the runners no longer slide over the dirt on the floor but form a path through it since the dirt etc. moves into the hollow recesses (1, 2) and thus the friction and wear between the runners and the floor is considerably reduced. Using these runners the force required to slide a chair over a carpeted floor is much less. The tips of the ribs on the end sides are preferably tapered which further facilitates the movement of the runners through the dirt and not over it.
