  • Fatigue-reducing handle grip and handle attachment for same
    Patent number: 4850079
    Abstract: Disclosed is a grip-enhancing device for a shaft handle which includes a grip portion generally coaxial with the shaft and sized to be grasped generally around its longitudinal axis by the palm and fingers of a user's hand. The grip-enhancing improvement comprises a rigid first portion extending substantially radially outwardly from the grip portion and presenting a surface positioned to bear against an edge of the user's hand. The surface has a cross-section which is spaced radially from and extends obliquely with respect to the longitudinal axis of the grip portion. A rigid second portion extends from the first portion in a direction oblique to the longitudinal axis of the grip portion and toward the user's wrist. The grip portion, the first portion and the second portion define a gap in which the user's hand is partially captured, thereby preventing axial and lateral slipping of the hand from the handle and reducing fatigue to the user.
