Abstract
A wave threaded fastener and system. A wave thread extends from the outer surface of the body and is made up of a profile wave and a lateral wave. The profile wave includes a plurality of profile crests and profile roots defining a plurality of profile thread widths. The lateral wave includes at least one lateral crest and at least one lateral root defining at least one wave period. Each wave period forms a period arc having a period arc angle and the sum of all period arc angles about the lateral wave equals three hundred and sixty degrees. Each of the profile crests and roots are aligned with corresponding lateral crests and roots and the wave thread travels one profile thread width per each period arc traveled.
Claims10
A wave threaded fastening system comprising:
- a wave threaded fastener comprising:
- a body comprising a central axis, an outer surface, a top end, and a bottom end, wherein said outer surface of said body forms a circumference about said central axis and wherein said circumference of said outer surface progressively decreases from said top end to said bottom end;
- and
- an outer wave thread extending from said outer surface of said body, said outer wave thread comprising a profile wave and a lateral wave;
- wherein said profile wave is a continuous wave extending from said top end of said body to said bottom end of said body, wherein said profile wave comprises a plurality of profile crests and profile roots defining a plurality of profile thread widths, and wherein a line intersecting each of said plurality of roots defines said outer surface of said body;
- wherein said lateral wave comprises at least one lateral crest and at least one lateral root defining at least one wave period, wherein each of said at least one wave period forms a period arc about said central axis of said body, wherein each period arc has a period arc angle, and wherein a sum of all period arc angles about said lateral wave equals three hundred and sixty degrees;
- and
- wherein each of said plurality of profile crests is substantially aligned with a corresponding lateral crest and each of said profile roots is substantially aligned with a corresponding lateral root such that said wave thread travels one period thread width per period arc traveled;
- and
- a workpiece comprising at least one inner surface, wherein said at least one inner surface comprises at least one inner wave thread dimensioned to engage with said outer wave thread of said wave threaded fastener.
