Emery Energy Ski Touring Binding circa 1990

Backcountry skiing history.

Backcountry skiing history.

In the late 1980s and 1990s an obvious transition to composites was happening in ski touring binding engineering. Important plastic components in this Emery Energy binding are the heel-toe connector plate and the rear latch plate mounted on the ski. As occurred with many backcountry bindings over the years, the Energy heel lifter appeared to be somewhat of a design afterthought and was easily detached and accidentally lost, as is the case here. In our view, the most unique feature of the Emery Energy is the “pass through” toe pivot frame as detailed below. We do need help dating this binding, please leave comments.

The binding has an odd pivot that allows the toe unit to pass through a vertical 'wishbone' frame, battling the inherent limitation of including an alpine-like toe that would normally impede forward pivoting of the bindings. Quite smart.

The Emery Energy touring binding has an odd pivot that allows the toe unit to pass through a vertical ‘wishbone’ frame, battling the inherent limitation of including an alpine-like toe that would normally impede forward pivoting of the bindings. Quite smart, as this also located the pivot much closer to optimal ergonomics rather than it being forward as with many other plate bindings. This unique mechanical sets the Energy apart from any other touring binding, and we wonder if it would still be a viable configuration.

In tour mode, note the front unit moving out of the pivot frame.

Overhead, note the full alpine-like heel clamp that's been 'skelatized' to reduce weight.

Overhead, note the full alpine-like heel clamp that’s been ‘skelatized’ to reduce weight, about 28.5 ounces, 808 grams, per binding.

Fixed heel downhill latching system, simply blade-like parts on ski mate with slots under plate at heel.

Fixed heel downhill latching system, simple blade-like parts on ski mate with slots under plate at heel, they slide in and out with a forward and back motion controlled by a thumb lever at the rear of the binding. This type of latching system, later using rods instead blades, is one of the Emery defining features. It’s simple and light, but was prone to problems with not easily engaging if ice prevented perfect alignment of the fixtures. In an ideal world you could switch modes with your boot in the binding, but most people found that removing the ski during mode switching was much easier then reaching down and rearward to manipulate the small lever at the rear of the binding..
