Vacuum sweeper drive belt.

摘要

An endless elastomeric vacuum sweeper belt (28) for use in a vacuum sweeper (10) having a diamond pattern drive surface. A first set of ribs (38) project inwardly in a substantially diagonal direction along the drive surface of the belt. A second set of ribs (40) project inwardly along the drive surface (30) of the belt in a substantially diagonal direction opposite the direction of the first set of ribs. The first and set second set of ribs together define a diamond-like pattern on the drive surface as well as a number of particle recesses (42) for the temporary collection of matter. Each rib includes knife-like edge portions (44) to increase the traction of the belt on a drive surface by cutting, loosening and expelling foreign matter lodged between the belt drive surface and the rotation member and/or the drive source of the vacuum sweeper.
