Here, as the appellants recognize, the admitted prior art and Rohrer '143 each utilize a spring arm having a generally perpendicularly-extending flange on the end thereof in order to engage a notch in the base of a pivotally-mounted blade, and thereby latch the blade in an extended position. Both references employ cams (347 in the case of the admitted prior art and 18 in the case of Rohrer '143) on the bases of adjacent tools that are pivotally mounted on the same axis as their respective blades for the purpose of engaging the end of the flange in such a manner so as to lift the flange from the notch, and thus unlatch the blade. The flange 318 of the admitted prior art, while extending from spring arm 316 at approximately a 90E angle, has a significant radius of curvature on the inside corner (see Fig. 3). The flange of Rohrer '143, however, extends from spring arm 13 at 8Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 NextLast modified: November 3, 2007
