Patent ID: 8117796

Claim:
A system of attaching and aligning both parallel and transverse reinforcing bars for supporting a concrete matrix, comprising: a plurality of substantially identical molded plastic clips for alternatively attaching and holding two parallel reinforcing bars of equal diameter or two transverse reinforcing bars of equal diameter, each clip including: two transverse supports; two pairs of lower legs extending downwardly from the two transverse supports, the two pairs of lower legs defining spaced lower seats of a first diameter, each pair of lower legs having a lower gap defining an opening from lower ends of the lower legs to the lower seats; two pairs of upper legs extending upwardly from the two transverse supports, the two pairs of upper legs defining spaced upper longitudinal seats parallel to the lower seats and having diameters equal to the first diameter of the lower seats; two longitudinal supports extending between the two pairs of upper legs, the two longitudinal supports joining upper ends of one pair of upper legs to upper ends of the other pair of upper legs, the two longitudinal supports having an upper gap therebetween defining an opening to the upper longitudinal seats, the upper gap being larger than the lower gap when each clip is in an unstressed position; and two spaced upper transverse seats defined on lower surfaces of the two longitudinal supports, the upper transverse seats being transverse to the lower seats and having diameters equal to the first diameter of the lower seats.
