Abstract
Abstract Disclosed herein is a handle for tools and sporting equipment which reduces fatigue and tension. The handle comprises an elongated member equipped with a grip at one end which is disposed at an angle from the longitudinal axis of the elongated member corresponding to the natural angle of the hand and wrist in a gripping position. The handle has a cross-section of generally oval shape corresponding to the shape of the opening between the palm and the fingers when the hand is closed, and is perferably slightly tapered.

Claim 1
Independent Claim
207 words
A handle for implements such as tools and sporting equipment adapted to be held by a hand and moved by at least a forearm of a user comprising a gripping portion, means adapted to connect said gripping portion to an elongated member so that when said gripping portion is held by said user said elongated member is intermediate said gripping portion and said implement, the longitudinal axis of said elongated member being substantially coaxial to the longitudinal axis of said implement whereby rotation of said longitudinal axis of said forearm of said user causes substantially coaxial rotation of said elongated member of said implement about said longitudinal axes, said elongated member is intermediate said gripping portion and said implement, and means being constructed arranged whereby said gripping portion is angularly disposed from said elongated member so that when placed in the hand of said user the longitudinal axis of said elongated member is substantially coaxial to the longitudinal axis of said forearm of said user, and wherein said gripping portion has a substantially oval cross-section, said oval cross-section decreasing in circumference as the distance from said connecting means increases, and said substantially oval cross-section has substantially flattened end surfaces traverse to the long axis of the oval.
Claim 2
Dependent Claim
207 words
A handle for implements such as tools and sporting equipment adapted to be held by a hand and moved by at least a forearm of a user comprising a gripping portion, means adapted to connect said gripping portion to an elongated member so that when said gripping portion is held by said user said elongated member is intermediate said gripping portion and said implement, the longitudinal axis of said elongated member being substantially coaxial to the longitudinal axis of said implement whereby rotation of said longitudinal axis of said forearm of said user causes substantially coaxial rotation of said elongated member of said implement about said longitudinal axes, said elongated member is intermediate said gripping portion and said implement, and means being constructed arranged whereby said gripping portion is angularly disposed from said elongated member so that when placed in the hand of said user the longitudinal axis of said elongated member is substantially coaxial to the longitudinal axis of said forearm of said user, and wherein said gripping portion has a substantially oval cross-section, said oval cross-section decreasing in circumference as the distance from said connecting means increases, and said substantially oval cross-section has substantially flattened end surfaces traverse to the long axis of the oval.
Claim 3
Dependent Claim
14 words
A handle as recited in claim 1 wherein said angular disposition is from 15°-25°.
Claim 4
Dependent Claim
139 words
A handle for implements such as tools and sporting equipment adapted to be held in a hand and moved by at least a forearm of user comprising an elongated member and an angularly disposed gripping portion at one end of said elongated member, said gripping portion having a substantially oval cross-section, said oval cross-section decreasing in circumference as the distance from and said elongated member increases, said substantially oval cross-section having a substantially flattened end surfaces transverse to the long axis of the oval, said angular disposition of said gripping portion at an angle of from 15°-25° from said elongated member such that said gripping portion is adapted to be engaged by said hand of said user so that the longitudinal axis of said elongated member is substantially coaxial to the longitudinal axis of said forearm of said user.
Claim 5
Dependent Claim
139 words
A handle for implements such as tools and sporting equipment adapted to be held in a hand and moved by at least a forearm of user comprising an elongated member and an angularly disposed gripping portion at one end of said elongated member, said gripping portion having a substantially oval cross-section, said oval cross-section decreasing in circumference as the distance from and said elongated member increases, said substantially oval cross-section having a substantially flattened end surfaces transverse to the long axis of the oval, said angular disposition of said gripping portion at an angle of from 15°-25° from said elongated member such that said gripping portion is adapted to be engaged by said hand of said user so that the longitudinal axis of said elongated member is substantially coaxial to the longitudinal axis of said forearm of said user.
