A drive mechanism (100) is coupled to each mast (52) and is moveable upwardly and downwardly along the masts. An elongated elevating platform (58) extends between the masts. A connection frame (150) couples each end of the elevating platform to a respective one of the drive mechanisms (100). Each connection frame (150) is pivotally coupled to the drive mechanism (100). ## Claims ### Claim 1 An elevating platform assembly comprising: a generally vertical mast; a drive mechanism coupled to said mast and being moveable upwardly and downwardly along said mast; an elongated elevating platform extending from said mast; and a connection frame coupling said elevating platform to said drive mechanism, said connection frame being fixedly secured to said drive mechanism to maintain said elevating platform in a generally horizontal orientation in a single mast configuration and being pivotally coupled to said drive mechanism in a dual mast configuration, wherein the connection frame comprises at least one support pin, said at least one support pin resting on a generally concave support surface of said drive mechanism and being moveable along said support surface. ### Claim 2 (depends on 1) An elevating platform assembly according to claim 1 wherein said support surface is formed on a resting block carried by said drive mechanism. ### Claim 3 (depends on 1) An elevating platform assembly according to claim 1 wherein said connection frame comprises a pair of oppositely extending support pins, each support pin resting on an associated generally concave support surface of said drive mechanism and being moveable along said associated support surface. ### Claim 4 (depends on 3) An elevating platform assembly according to claim 3 wherein each support surface is formed on a respective resting block carried by said drive mechanism. ### Claim 5 (depends on 1) An elevating platform assembly according to claim 1 further comprising releasable locking structure to inhibit pivotal movement of said connection frame relative to said drive mechanism. ### Claim 6 (depends on 5) An elevating platform assembly according to claim 5 wherein said locking structure comprises at least one of an anti-rotation pin and an anti-backlash fastener acting between said connection frame and said drive mechanism. ### Claim 7 (depends on 3) An elevating platform assembly according to claim 3 further comprising releasable locking structure to inhibit pivotal movement of said connection frame relative to said drive mechanism. ### Claim 8 (depends on 7) An elevating platform assembly according to claim 7 wherein said locking structure comprises at least one of an anti-rotation pin and an anti-backlash fastener acting between said connection frame and said drive mechanism. ### Claim 9 An elevating platform assembly comprising: a pair of laterally spaced, generally vertical masts; a drive mechanism coupled to each mast and being moveable upwardly and downwardly along said mast; an elongated elevating platform extending between said masts; and a connection frame coupling each end of said elevating platform to a respective one of said drive mechanisms, each connection frame being pivotally coupled to said respective drive mechanism, wherein each connection frame comprises at least one support pin, said at least one support pin resting on a generally concave support surface of said respective drive mechanism and being moveable along said support surface. ### Claim 10 (depends on 9) An elevating platform assembly according to claim 9 wherein each support surface is formed on a resting block carried by said respective drive mechanism. ### Claim 11 (depends on 9) An elevating platform assembly according to claim 9 wherein each connection frame comprises a pair of oppositely extending support pins, each support pin resting on an associated generally concave support surface of said respective drive mechanism and being moveable along said support surface. ### Claim 12 (depends on 11) An elevating platform assembly according to claim 11 wherein each support surface is formed on a respective mounting block carried by said respective drive mechanism. ### Claim 13 (depends on 9) An elevating platform assembly according to claim 9 further comprising releasable locking structure to inhibit pivotal movement of each connection frame relative to said respective drive mechanism. ### Claim 14 (depends on 13) An elevating platform assembly according to claim 13 wherein said locking structure comprises at least one of an anti-rotation pin and an anti-backlash fastener acting between each connection frame and said respective drive mechanism. ### Claim 15 (depends on 11) An elevating platform assembly according to claim 11 further comprising releasable locking structure to inhibit pivotal movement of each connection frame relative to said drive mechanism. ### Claim 16 (depends on 15) An elevating platform assembly according to claim 15 wherein said locking structure comprises at least one of an anti-rotation pin and an anti-backlash fastener acting between each connection frame and said respective drive mechanism. ### Claim 17 An elevating platform assembly comprising: a generally vertical mast; a drive mechanism coupled to said mast and being moveable upwardly and downwardly along said mast; an elongated elevating platform extending from said mast; and a connection frame coupling said elevating platform to said drive mechanism, said connection frame being fixedly secured to said drive mechanism to maintain said elevating platform in a generally horizontal orientation in a single mast configuration and being pivotally coupled to said drive mechanism in a dual mast configuration, wherein said connection frame comprises a pair of oppositely extending support pins, each support pin resting on an associated support surface of said drive mechanism and being moveable along said associated support surface. ### Claim 18 (depends on 17) An elevating platform assembly according to claim 17 wherein each support surface is formed on a respective resting block carried by said drive mechanism. ### Claim 19 (depends on 17) An elevating platform assembly according to claim 17 further comprising releasable locking structure to inhibit pivotal movement of said connection frame relative to said drive mechanism. ### Claim 20 (depends on 19) An elevating platform assembly according to claim 19 wherein said locking structure comprises at least one of an anti-rotation pin and an anti-backlash fastener acting between said connection frame and said drive mechanism. ### Claim 21 An elevating platform assembly comprising: a pair of laterally spaced, generally vertical masts;
