A scaffold truss member and a scaffold truss connector. The scaffold truss member includes lower and upper horizontal members, joined by bracing members. The upper horizontal member terminates at each end with a coupling, while the lower horizontal member terminates without a coupling on either end.

A scaffold truss member and a scaffold truss connector. The scaffold truss member includes lower and upper horizontal members, joined by bracing members. The upper horizontal member terminates at each end with a coupling, while the lower horizontal member terminates without a coupling on either end. The scaffold truss connector includes a lower truss connector that has a channel, open on two ends to accommodate the lower horizontal member of a scaffold truss, and an upper truss connector, which is either integral or joined to the lower truss connector.

1. A scaffold truss connector for coupling two scaffold truss members in an end-to-end configuration, in combination with first and second scaffold truss members, each scaffold truss member comprising: an upper horizontal scaffold truss member and a lower horizontal scaffold truss member, each separated from the other but fixedly joined with a series of bracing members, at least one of said bracing members comprising a vertical coupling bracing member having a series of annular members adapted to couple with a horizontal scaffold member end connector, said annular members vertically spaced apart on said vertical coupling brace, said upper and said lower horizontal scaffold members having a first and second end respectively, first and second upper end connectors fixedly positioned on said first and second ends of said upper horizontal scaffold truss member, each upper end connector configured to connect to a scaffold vertical member at an annular member positioned on said vertical scaffold member;said scaffold truss connector comprising a lower truss connector comprising a channel having two terminating open ends, a bottom portion and two sidewall portions extending from said bottom portion, said sidewall portions and said bottom portion defining an open top channel portion therebetween, at least at said two terminating ends of said channel, said channel bottom portion being shaped near each of said terminating ends to cradle a respective said lower horizontal scaffold truss member of one of said scaffold truss members when inserted into one of said terminating ends of said channel, said lower truss connector further having a leg portion that extends outwardly and substantially perpendicular to said channel bottom, said leg portion configured to releasingly engage an upper truss connector; and an upper truss connector member comprising a vertical scaffold member having a series of annular members vertically spaced apart, one of said annular members being releasingly couplable with respective said upper horizontal truss member end connectors of said scaffold truss members. 2. The combination of claim 1 wherein each upper end connector is configured to be latchable to an annular member on a scaffold vertical member. 3. The combination of claim 2 wherein the annular members are cups. 4. The combination of claim 2 wherein the annular members are rosettes. 5. The combination of claim 2 wherein said upper end connectors are slidably latchable. 6. The combination of claim 2 wherein said upper end connectors are pivotably latchable. 7. A scaffold truss connector for coupling two scaffold truss members in an end-to-end configuration, in combination with first and second scaffold truss members, each scaffold truss member comprising: an upper horizontal scaffold truss member and a lower horizontal scaffold truss member, each separated from the other but fixedly joined with a series of bracing members, at least one of said bracing members comprising a vertical coupling bracing member having a series of annular members adapted to couple with a horizontal scaffold member end connector, said annular members vertically spaced apart on said vertical coupling brace, said upper and said lower horizontal scaffold members having a first and second end respectively, first and second upper end connectors fixedly positioned on said first and second ends of said upper horizontal scaffold truss member, each upper end connector configured to connect to a scaffold vertical member at an annular member positioned on said vertical scaffold member;said scaffold truss connector comprising a lower truss connector comprising a channel having two terminating open ends, a bottom portion and two sidewall portions extending from said bottom portion, said sidewall portions and said bottom portion defining an open top channel portion therebetween, at least at said two terminating ends of said channel, said channel bottom portion being shaped near each of said terminating ends to cradle a respective said lower horizontal scaffold truss member of one of said scaffold truss members when inserted into one of said terminating ends of said channel, said lower truss connector further having a leg portion that extends outwardly and substantially perpendicular to said channel bottom, said leg portion further forming an upper truss connector, and having a series of annular members vertically spaced apart on said leg portion, one of said annular members being releasingly couplable with respective said upper horizontal truss member end connectors of said scaffold truss members. 8. A method of assembling first and second scaffold truss members in an end-to end configuration; comprising the steps of: providing first and second scaffold truss members, each comprising: an upper horizontal scaffold truss member and a lower horizontal scaffold truss member separated from the other but fixedly joined with a series of bracing members, at least one of said bracing members comprising a vertical coupling bracing member having a series of annular members adapted to couple with a horizontal scaffold member end connector, said annular members vertically spaced apart on said vertical coupling brace, said upper and said lower horizontal scaffold members having a first and second end respectively, first and second upper end connectors fixedly positioned on said first and second ends of said upper horizontal scaffold truss member, each upper end connector configured to connect to a scaffold vertical member at an annular member positioned on said vertical scaffold member;providing a lower truss connector comprising a channel having two terminating open ends, a bottom portion and two sidewall portions extending from said bottom portion, said sidewall portions and said bottom portion defining an open top channel portion therebetween, at least at said two terminating ends of said channel, said channel bottom portion being shaped near each of said terminating ends to cradle a respective said lower horizontal scaffold truss member of one of said scaffold truss members when inserted into one of said terminating ends of said channel, said lower truss connector further having a leg portion that extends outwardly and substantially perpendicular to said channel bottom, said leg portion configured to releasingly engage an upper truss connector;providing an upper truss connector comprising a vertical scaffold member having a series of annular members vertically spaced apart, one of said annular members being releasingly couplable with respective said upper horizontal truss member end connectors of said scaffold truss members;coupling said first end of said upper scaffold truss member of said first scaffold truss member to said upper truss connector;coupling said second end of said upper scaffold truss member of said second scaffold truss member to said upper truss connector;cradling said first end of said lower scaffold truss member of said first scaffold truss member in said lower truss connector;cradling said second end of said lower scaffold truss member of said second scaffold truss member in said lower truss connector; andcoupling said lower truss connector to said upper truss connector. 9.
