First Claim
Patent Images
1. A connecting device for a dowel bar and frame wherein the frame includes a U-shaped portion over the dowel bar and the frame also includes a horizontal cross-member, the connecting device comprising:
- a spring coil wire;
the spring coil wire comprising at least one circular member;
the at least one circular member forming a cavity;
wherein the cavity is capable of receiving the dowel bar;
wherein the at least one circular member secures the dowel bar;
the spring coil wire having a first end and a second end;
wherein the second end has a hook for engaging the horizontal cross-member of the frame;
the spring coil wire comprising an arm longitudinally extending from the at least one circular member;
wherein a longitudinal axis of the arm is parallel to a longitudinal axis of the dowel bar;
wherein the arm prevents movement of the U-shaped portion of the frame toward the at least one circular member;
wherein the connecting device secures the dowel bar and the frame without utilizing welds;
the spring coil wire bendable wherein the second end can be selectively moved to disengage the spring coil wire from the frame.
