Claim 8

An expansion joint cover assembly as set forth in claim 5 wherein: a. said second channel member including a second sub-channel member formed by laterally spaced upright elongate side wall members and a bottom wall member extending therebetween and including an elongate top wall member removably secured to one said second sub-channel side wall member, said last named wall members extending longitudinally the length of said second channel member and defining an elongate cavity therebetween, the second channel top wall member having a free edge portion generally above and in relative spaced relation to a free edge portion of the last named other side wall member, said free edges defining an elongate slot therebetween facing toward said first channel member and communicating with said cavity; b. said other lateral side portion being inclined downwardly and outwardly of said mid-portion extending through said second channel member elongate slot, said inclined portion being in spaced relation to the second channel member wall members, the lower surface slidably and pivotally engaging the free edge of the second channel other side wall member and being supported thereby.

Claim 9

An expansion joint cover assembly as set forth in claim 6 wherein: a. said first and second channel members being recessed in said respective adjacent structural sections; b. said structural sections each having an outer surface portion disposed in angular relation to a respective surface defining said joint, said top wall members each having an outer surface being substantially flush with a respective structural section outer surface; c. said mid-portion being substantially flat and being substantially flush with said top wall member outer surface forming a smooth surface transversly thereacross; d. said cover member lower surface opening downwardly and including a plurality of transversly spaced ribs extending longitudinally the length of said cover member, said ribs engaging respective other side wall members'' free edges urging said cover member to maintain a centrally located position over said joint; e. said sub-channels other side walls'' free edges each being transversly rounded; f. said sub-channels one side wall members, each having an upper surface portion with an elongate way therein; g. an elongate rib portion on a lower surface of each said top wall member cooperatively engaging a respective way; h. each said top wall member free edge portion having an inclined portion extending downwardly and outwardly of said top wall member upper surface to eliminate a sharp corner at each said free edge portion; i. said top wall members'', sub-channel members'' and cover member shapes being adapted to their manufacture by an extrusion process; j. said top wall members'' outer surfaces and the cover member flat portion having means thereon to provide a traction surface; k. said side wall members and bottom wall members of each sub-channel member being integral.
