Hand-secured pushbutton control device
First Claim
1. A control device comprising a body which can be maintained in a substantially fixed position relative to the palm and back of the user'"'"'s hand without immobilizing the user'"'"'s fingers;
- and a plurality of sets of switch means supported by said body, each of said sets of switch means being aligned with and adapted to be operated by a different finger, each of said pushbutton sets comprising first, second, third, and fourth switch means, said first and second switch means being adapted to be actuated by pivoting of the aligned finger in first and second senses, respectively, about the center of said hand, in directions substantially parallel to the palm, from a rest position to positions corresponding to the opening and closing of the hand;
said third switch means in each set being adapted to be operated by the aligned finger through the movement of the finger in a direction substantially perpendicular to the palm from the rest position to a position relatively remote from the palm; and
said fourth switch means in each set being adapted to be operated by the aligned finger through the movement of the finger in a direction substantially perpendicular to the palm, from the rest position to a position relatively proximate to the palm.

Abstract
The device engages the hand of the operator and maintains same in a fixed position while permitting movement of the fingers. A first rigid part is adapted to be situated adjacent the palm. A second rigid part, aligned with the first part, is adapted to be situated adjacent the back of the hand. The first and second parts are mounted in a fixed, spaced relationship to engage the hand therebetween. The pushbuttons are mounted in sets, each set being aligned with a different finger and adapted to be operated by the pivotal movements of the finger in its plane as the finger is moved relative to the palm.
