Spring lift for shoes

Abstract

In the heel of a shoe is a cavity in which the end of a leaf spring is coiled around and anchored in a fixed pin biased so that the leaf spring is normally urged away from the adjacent portion of the heel. The leaf spring is at an incline downwardly and rearwardly along an inclined bottom surface of the heel and has on it a complemental portion of the heel. The leaf spring is held against said inclined surface by a pivoted lever which latter is pressed by a coil spring around its pivot against the leaf spring thereby to press the leaf spring against the inclined surface of the heel. The lever is covered by a complemental heel portion. Between the lever and the adjacent forward part of the heel is a compressible filler which in this illustration is sponge rubber to fill the space therewith. A latching device is provided in the cavity to latch the lever in the raised position until the leaf spring has completed its downward cycle. A release device in the cavity connected to the leaf spring is provided to release the latching device when the leaf spring is in its downstroke.
