Abstract

1360728 Roller conveyers M SAKAMOTO 26 July 1972 34859/72 Heading B8A [Also in Division E1] A floor comprises a plurality of portable units 10 each consisting of a base panel 12 which rollingly receives balls 14 retained by bolts 16, walls 18 and cover-plates 32. Bolt heads 28 are slotted to receive ribs 36 of the plates 32 each of which has four arcuate edge recesses 34 conforming to the curvature of the balls. The plates are removable for ease of maintenance and the bolts are adjustable for varying frictional engagement with the balls. The units may be located relative to each other by pins and bores (42, 44), Fig. 9 (not shown). In a modification, Figs. 6, 7, the base panel 12 has rails 46 forming pockets for the balls 14 which are also located by indented edges of apertures 54 in a cover-plate 52. The flooring is stated to be suitable for ballroom dancing or for the transporting of objects. (For Figures see next column.)
