US Patent 10041755 Safety wrist strap for a crossbow crank handle

A safety device for a crossbow includes a wrist strap with a crank aperture in a palm portion thereof, and is secured around a user's wrist with the crank aperture over the palm of the user's hand. The crank aperture allows passage therethrough of a shaft of a crossbow crank, but prevents passage of a handle; wearing the wrist strap, the user can grasp the handle with the shaft extending through the crank aperture away from the palm of the user's hand. The wrist strap can be divided at its dorsal-wrist portion and include a closure to allow the wrist strap to be secured around or removed from the user's wrist as desired. Restraint of the crank handle by the crank aperture prevents uncontrolled spinning of the crossbow crank.
