ABSTRACT:
A sprinkler head assembly has a stamped mounting element for supporting a thermally activated triggering member in a sprinkler head assembly, and a method forms the same. The mounting element comprises a central base including a seat for supporting the triggering member. A first pair of arms, having a longitudinal extent, extend from a first face of the base at an angle less than 180 degrees. A second pair of arms, having a longitudinal extent, extend from the first face of the base at an angle less than 180 degrees. The longitudinal extent of at least one of the arms is greater than the longitudinal extent of the other arms to define a recess for cooperatively engaging the sprinkler head assembly. The mounting element is stamped from generally planar stock to form arms having varied lengths and, thus, create a saddle-shaped recess that slidably mounts on a frame of the sprinkler head assembly. The mounting element is preferably formed by progressive stamping techniques and accommodates various dimensions and tolerances of the sprinkler head frame and thermally responsive triggering member.
