1370215 Mats M KESSLER 12 June 1972 [28 June 1971] 27272/72 Heading A4S Mat sections 2, 3, 4, Fig. 1 providing a perforated frictional surface for walking upon or for preventing slipping of a car wheel, each consist of a first series of parallel plastics top strips 6 injection moulded integrally with a second, transverse series of more widely spaced parallel bottom strips 9, 9a, 9b, the mat sections 2, 4 being detachably secured together at adjacent side edges by latching links 12 each of which is integral at one end 13 with a strip 6a of the mat section 2, has a neck portion 14 extending under the strip 6b of the mat section 4, and has a latching member 16 which extends upwards between strips 6b and 6c of the mat section 4, the member 16 being forced between and overlying bottom strips 9c, 9d of the mat section 4. Extensions 9', 9a', of the strips 9, 9a space the adjacent side edges of the mat sections. A separate latching link for use where the integral link is removed in cut down sections has a latching member at each end which fits between the two outermost top strips of adjacent mat sections. The mat sections 2, 3 are detachably joined along adjacent end edges by joining pieces 20 which have a link bar 22 and end tabs 24, 25 which underlie adjacent strips 6 in the two sections. Filler strips 26, Fig. 5 with end tabs 26' 28' underlying adjacent strips 6 are inserted between appropriate strips 6 to form a pattern or design and a ramped edge 32 Fig. 9 is connected to a side or end of the mat by connecting links which engage in a space between a strip 38, connected to the main body 40 of the ramped edge, and the main body, and in spaces between strips 6 of the adjacent mat section: The upper surfaces of the strips 6 are corrugated or dimpled to increase friction and the under surface of the strips 9 cut away to aid drainage.
