Abstract
A hinge and hold-open assembly is disclosed having a pair of hinge straps and an integral hold-open spring and pivot pin member. The spring and pin member has a pivot pin portion pivotally connecting the hinge straps and a spring portion which is operatively engaged by a cam on one of the hinge straps so as to be normally relaxed in a closed hinge condition. Then on relative pivotal movement between the hinge straps, the spring portion is radially flexed and then relatively abruptly partially unflexed to yieldingly establish and hold an open hinge condition and with less effort required to establish the hold-open condition than is required to release same.
