Abstract
A nut that includes a body having an aperture disposed within the body, threads located within the aperture of the body, and a plurality of gripping areas disposed along a circumference of the body. The plurality of gripping areas provides visual and tactile directional signals as to the rotational direction required to attach or detach the nut to or from a threaded member. The nut may be used for attaching a water filter system to a water faucet.
Claims10
A nut, comprising:
- a body having an aperture disposed within the body and a longitudinal axis;
- threads located within the aperture of the body;
- and
- a plurality of gripping areas disposed along a circumference of the body and completely through the body along the longitudinal axis;
- wherein each of the plurality of gripping areas comprises a pressure-bearing face having an angle of leverage α and a non-pressure-bearing face having an angle of leverage β;
- wherein the angle of leverage α is greater than the angle of leverage β;
- wherein the plurality of gripping areas provides visual and tactile directional signals as to the rotational direction required to attach or detach the nut to or from a threaded member;
- wherein the angle of leverage α is from about 30 degrees to about 90 degrees for the pressure bearing faces and the angle of leverage β is from about 10 degrees to about 60 degrees for the non-pressure bearing faces;
- and
- wherein the gripping areas include a curvature that is defined by a finger recess depth (D) that ranges from about 0.115 inches to about 0.220 inches and a conic arc, and wherein the conic arc is further defined by a RHO value of the conic arc that ranges from about 0.5 to about 0.75, an angle λ of the conic arc trailing edge that ranges from about 130 degrees to about 190 degrees, and a radius (B) of the non-pressure bearing face that ranges from about 0.3 inches to about 1.5 inches.
A method for providing a nut with visual and tactile signals for attaching the nut to a threaded member, comprising:
- providing a nut body having a longitudinal axis and an aperture disposed within the body and about the longitudinal axis;
- forming a plurality of unidirectional gripping areas along a circumference of the body and completely through the body along the longitudinal axis;
- forming a pressure bearing face on each of the plurality of unidirectional gripping areas;
- forming a non-pressure bearing face on each of the plurality of unidirectional gripping areas;
- and
- forming each of the pressure bearing faces to include an angle of leverage α and each of the non-pressure bearing faces to include an angle of leverage β, wherein the angle of leverage α is greater than the angle of leverage β such that the plurality of gripping areas provides visual and tactile directional signals as to the correct rotational direction required to attach the nut to a threaded member;
- wherein the angle of leverage α is from about 30 degrees to about 90 degrees for the pressure bearing faces and the angle of leverage β is from about 10 degrees to about 60 degrees for the non-pressure bearing faces;
- and
- wherein the gripping areas include a curvature that is defined by a finger recess depth (D) that ranges from about 0.115 inches to about 0.220 inches and a conic arc, and wherein the conic arc is further defined by a RHO value of the conic arc that ranges from about 0.5 to about 0.75, an angle λ of the conic arc trailing edge that ranges from about 130 degrees to about 190 degrees, and a radius (B) of the non-pressure bearing face that ranges from about 0.3 inches to about 1.5 inches.
