We find improvements on existing equipment used in shooting and hunting. I recently found one with a crossbow.
By Norman Johnson
While observing a number of different crossbows being cocked, I could clearly see a need for a better way this could be accomplished. Cocking a 150-175 pound crossbow via direct pull, with both hands, requires considerable strength. The next easiest method is performed by means of a rope cocking aid utilizing a long cord with T-handles on each end fitted to a pair of pulleys that doubled back to the bow frame to reduce pull weight by 50 percent. Though substantially easier, this too can be quite difficult for the aging or incapacitated hunter who really needs help.
As alternatives for easier crossbow cocking, there are various methods of cranking the bow by means of a pulley and hand crank. Most of these are quite effective but not totally uncomplicated to operate and most are noisy out in the woods. They are usually set up to work on one style of crossbow only. There also are specialized cocking systems using gas cylinders and electrical devices rigged to individual crossbows that can be quite expensive.
This was sufficient to inspire the design of a universal crank-cocking system that could be adapted to a number of different crossbows, one that is safe, quiet and easy to carry and attach.
