Marker EPF Ski Binding Module

This project was dedicated to making a hybrid piste and alpine touring binding which improves a module that 5 generations of Marker ski bindings are built upon. By designing the next generation of this EPF (Extended Performance Frame) module, the company Marker would be able to improve a series of ski touring bindings through 3 new resource and cost-efficient parts. Weight, user friendliness, and using materials and production methods that have been used by Marker in the past, were key constraints in the design process. The design should easily be incorporated to other Marker bindings and would hugely advance the effortlessness of ski touring for beginners and regular on-piste skiers who would like to get more adventurous. The goal was to redesign the ascent aid on this compound frame, so that you can cycle through every of the 3 levels of the mechanism in an upright position, with the simple motion of any type of ski pole.

To fold the mechanism down 2 steps, you can use the trapezoid rills in the back of the ascent aid to push.

To retrieve the ascent aid back one position, you can use the redesigned plastic parts at the end of the brake levers to hook, and lever the mechanism back one step. By lastly using the plate of the ski pole you can hook at the center of the rill at the back and pull up the ascent aid into its fully retracted position, without ever needing to bend down.

The white plate is mounted to the ski and the above show movement is the way to unlock and respectively lock (top to bottom) the Epf plate to the ski to change the binding between locked ridable mode and touring mode.
