  • Coupler for flexible scaffold system
    Patent number: 7147398
    Abstract: A two coupler apparatus for interconnecting two scaffolding members wherein at least one coupler is defined by: a base interconnected to a second coupler and a lever hinged to the base. The base and the lever define a pocket for laterally receiving a length of a scaffold member. An arm is hinged to the base and the lever has a slot sized to receive the arm. The arm defines a hole positioned to extend beyond the lever when the arm is within the slot. A wedge is adapted for insertion through the hole to slidably move against the lever when the arm extends within the slot to wedge the arm within the lever whereby the scaffold member is locked within the at least one coupler.
