I am developing a new split interface and am looking for feed back.
Right now I have one prototype. I am looking for people with engineering and machining experience or just money to help me take this to the next level. I have been calling around to different companies to see if they are interested but most at this stage won't bite because of the small returns in the split market.
Description of the invention is as follows. The interface is a two layer plate that bolts to the bottom of a basic snowboard boot. In the top layer of this plate there is a bar that is used to attach to a NNN binding in ski mode no point in reinventing the weal. The bottom layer of this plate contains a series of spring loaded pins and engagement tabs so that in snow board mode the binding are attached to the snowboard by placing a first sliding the two halves of the split board together placing the board on the ground placing the binding on the "pucks" while the foot is strapped in and twisting the binding 90 degrees until the pins engage and lock the assembly together. This motion is similar to screwing a lid and a jar. To release the binding the rider would simply bend down pinch the two release arms "which are on the outside of the boot" together and begin twisting the binding at which point the release arms could be released.
Figure 1 and 2 show the general idea of the the whole system. In figure two note the the hooks found toward the ends of the board on the voile system are located in the pucks. In their place are overlapping tabs.
Figures 3 and 4 show the pucks. Note the hooks, engagement tabs, pin holes, and gaps where the hooks come together. These gaps are to prevent icing.
Figures 5 show the interface plate form the bottom. Here can be six contact pints to preventing the rocking slop that is present in the voile system. Also can be seen are two tabs that hold the assembly down to the pucks. Above one of these tabs can be seen one of the locking pins. Out the side of the assembly can be seen the two release arms.
Figure 7 show the two layers of the plate. The elements of the lower plate are riveted together. The upper layer will be bolted to the lower layer by the rider at home to his or her stance angle. This is because the upper layer contains the NNN bar and therefor must align to the binding and the lower layer contains the engagement pins and there for must align to the longitudinal axis of the board.
Figure 8 shows the lower layer. Containing the pins and their springs. This mechanism is similar to the lock and pocket knives where the release for the knife is on the back of the handle. The design work of this mechanism is not completed I do not know exactly how to shape the spring or the exact shape of the spring head.
There are other way to make this mechanism that could all be viable. The critical requirement is that the locking mechanism does not allow any rotation of the assembly.
Figure 9 through 11 is an animation of showing how the pin engages as the binding is rotated onto the puck. Though it is not show you can see how the spring would deflect.
Figure 12 shows how the binding assembly locks the puck together so that the two halves of the snowboard can not slide apart.
Figure 13 shows a critical gap between the bottom of the engagement tab of the plate and the top of the split board. This gap is there to prevent icing. The tab only holds the binding down to the board the "contact tabs" serve the purpose of holding the binding up.
There is a patent pending on the invention so if you need permission ask.
