Emery Medium Ski Touring Binding – 1980s?

In the ongoing attempt to make lighter weight AT ski touring bindings, an occasional ploy has been to eliminate safety release altogether, or more commonly, eliminate vertical release at the heel. These are sometimes called “approach bindings” due to their use with mountain climbing boots instead of ski boots as a tool for accessing climbing areas. When such bindings are used with shorter skis and softer boots, they probably resulted in less injury than one would at first suspect. Nonetheless, in certain situations this sort of binding could result in serious hurt, so they’re a specialized tool.

One such binding is the Emery Medium, a minimalist plate binding that does have non-adjustable side release, but no vertical release.

Emery Medium, all of it. Boot was held into the rear of the binding with a buckle and strap. The toe wire was compatible with DIN shaped AT boot soles. To use climbing boots, one had to hand-make different shaped toe wires.

Boot in binding (modern boot, sorry). Rather than messing around with an over-center pivot latch or full-on release mechanism, the Medium holds the boot heel with a simple strap system. Not particularly stable and of course no release, but simple.

Rotational release at both plates coming completely off the ski. To prevent ski loss a retention cord could be added using the slot visible at extreme left.

Loop of metal (left) slides in and out under spring tension, controlled by lever on heel fitting. The loop engages the slots visible to right, thus latching the plate down for skiing, and releasing it for touring.
