  • Patent number: 6148482
    Abstract: A grip for a tool handle or other surface intended for gripping by a user, may be provided by a durable, expanded elastomeric material. Formation of the grip, and installation thereof on a handle may be effected to provide pre-loading of a normal force against the handle, requiring substantially less normal force by a user on order effect frictional engagement of a handle by the grip. The grip may also be formed to provide micro-pressure along ridges impressed into the hand of the user alternating with cavities in a surface of the grip for receiving intrusions of the hand. Thus, mechanical engagement, rather than strictly frictional engagement may be effected. Grips made in accordance with the invention have been demonstrated to provide sufficient engagement with a hand and a tool handle to permit a user to apply the maximum physical force available from the user.

    Abstract: An ergonometric handle is shaped so as to encourage a natural working grip, thereby increasing user comfort and enabling a user to use a tool incorporating said handle for a longer period of time with reduced fatigue to the tissues, nerves, tendons and bones of the hand. The handle may be angularly disposed relative to the long axis of the tool and the ends of the handle are smaller in width than the middle in order to accommodate the smaller gripping circumferences of the index and small digits. Thus the cross sectional shape of the handle is oblong and when viewed from the side is humpbacked. The grip honors the varying ratios of the digits to the metacarpals. The handle also has indentations in it to enhance the placement of the digits in the natural gripping position. These indentations form a hand imprint in the handle.
