Abstract
Various embodiments are directed to systems, apparatus and methods configured for anthropometrics data/measurement acquisition such as for fitment of handguns, hand tools, weapons and the like.
Claims13
Apparatus for acquisition of functional gripping hand anthropometrics, comprising:
- a forearm cradle, configured to receive a forearm of a user and to provide dynamic support and alignment to a functionally gripping hand of the user;
- a lower grip, configured to be normally grasped by the middle, ring and little fingers of the functionally gripping hand, and to adjust position with respect to the forearm cradle in response to a positioning of the functionally gripping hand;
- an upper grip, coupled to a top portion of the lower grip and configured to be grasped by the thumb and trigger finger of the functionally gripping hand to measure thereby a circumferential grip distance associated with the thumb, thumb crotch, and trigger finger of the functionally gripping hand;
- a trigger, adjustably coupled to the grip measuring device via an adjustable Trigger Finger Pull Length Device (TFPLD) and configured to be operated by the trigger finger of the functionally gripping hand to measure thereby a trigger finger length of the functionally gripping hand;
- and
- a Trigger Finger Pull Force Device (TFPFD), coupled to the trigger, for measuring a dynamic trigger finger pull force of the functionally gripping hand.

A method of functional grip fitment, comprising:
- receiving a user forearm in a forearm cradle configured to provide dynamic support and alignment thereto;
- receiving a first portion of a functionally gripping user hand at a lower grip operatively aligned with the forearm cradle and configured to be normally grasped by a middle finger, ring finger, and little finger of the functionally gripping hand, and configured to adjust position with respect to the forearm cradle in response to a positioning of the functionally gripping hand;
- receiving a second portion of the functionally gripping hand at an upper grip operatively coupled to a top portion of the lower grip and configured to be normally grasped by a thumb and trigger finger of the functionally gripping hand, and configured to determine via a curvilinear surface a circumferential grip distance associated with the thumb tip, thumb crotch, centerline of trigger finger distal phalanx and trigger finger tip of the functionally gripping hand;
- receiving the trigger finger of the functionally gripping hand at a trigger adjustably coupled to the upper grip, and configured to determine via adjustment thereof a trigger finger length of the functionally gripping hand;
- and
- determining, in response to a dynamic trigger finger pull force exerted on the trigger by the trigger finger of the functionally gripping hand, a trigger finger pull force of the functionally gripping hand;
- and
- determine a handgrip fitment using the determined circumferential grip distance, trigger finger length, and trigger finger pull force of the functionally gripping hand.
