Sighting measuring angle (goniometer) with a built-in compass

摘要

A ski binding front jaw has a support member and a slide member which are independently supported for movement longitudinally of the ski. The support member has a pair of two-arm sole holder levers supported for pivotal movement about vertical axes, a first arm of each sole holder being adapted to engage a ski boot and the second arm engaging the slide member. A spring engages the support member and slide member and urges them rearwardly and forwardly, respectively, the slide member in turn urging the sole holders pivotally so that the second arms thereof are urged against the ski boot. Respective stops limit forward and rearward movement of the slide member and support member, respectively. A forward force exerted on the support member moves it forwardly relative to the slide member against the force of the spring, so that the first arms of the sole holders become spaced from the slide member and the second arms of the sole holders can pivot freely outwardly.
