Patent ID: 7065853

Claim:
A method of forming an apparatus having an engageable polygonal protrusion comprising: providing a continuous, rigid, deformable planar material; defining a predetermined pattern including a plurality of member sides operable to define a central hub, and a plurality of elongated legs each extending from a respective member side; cutting the planar material according to the predetermined pattern; deforming the planar material such that the plurality of member sides form a plurality of substantially opposed sides defining the central hub polygonal protrusion by forming congruent, complementary outside convex edges between each pair of parallel edges on adjacent member sides of the central hub polygonal protrusion, the complementary outside convex edges operable to reinforce each other in a complementary manner, the elongated legs providing an integral attachment surface defined by the elongated legs and adapted to be secured via an attachment to a rotatable object, the integral attachment surface adapted to distribute rotational forces from the central hub polygonal protrusion to the rotatable object, wherein deforming further comprises deforming the opposed sides such that a discontinuous seam is formed along one of the opposed sides; deforming the planar material at a line of demarcation between each of the member sides and corresponding elongated legs defined by the predetermined pattern, such that the elongated legs are adapted to be disposed along the surface of the rotatable object; disposing the central hub polygonal protrusion on the rotatable object substantially centered along a rotational axis defined by the intended rotational engagement of the rotatable object; and attaching, via the attachment, the integral attachment surface defined by the elongated legs to the rotatable object.
