Adjustable nut for faucet installation
A faucet mounting structure includes a threaded pipe and a threaded lock nut. The quick tighten and release adjustable lock nut includes a separate upper main body and a lower main which snap fit together. The upper main body includes downward extending lugs with inward facing threads which are urged against the outward facing threads of a faucet pipe to hold the pipe and thus, hold the faucet in a fixed position on a counter top. The downward extending lugs are captured in canted arcuate recesses in the lower main body. The canted arcuate wedge shaped side wall ramps biases the threaded lugs outward decreasing the diameter of the inner bore and pressing against the pipe threads as the lower main body is rotated clockwise with respect to the upper main body enabling the lock nut to slide upward over the threaded shank of the faucet until abutting the top portion of the threaded faucet pipe whereby rotating the lock nut causes cooperative engagement between the threaded lugs of the lock nut and the threaded faucet pipe tightening the lock nut threads around the threaded pipe.
1. An adjustable lock nut, comprising:
an upper main body and a lower main body;
said upper main body having a circular top surface including an upward extending peripheral ring;
said upper main body includes six downward extending spaced apart threaded lugs with interior threaded portions facing radially inward for cooperatively engaging a threaded pipe
said upper main body including a plurality of downward extending spaced apart smooth lugs, each smooth lug having an outward extending distal ridge extending around an outer edge;
said spaced apart threaded lugs extending from a plurality of corresponding ovoid shaped base members which integrally connect to said upper main body by a connecting portion at one end of said ovoid shaped member biasing said threaded lugs inwardly for cooperatively engaging said threaded pipe;
said lower main body including an annular flat ring with a cylindrical rim extending downward from a central portion of said flat ring;
said cylindrical rim having spaced apart inward facing arcuate shaped ramps each one formed from a wedge shaped step, each arcuate shaped ramp being canted and terminating at a distal end by an inward facing lug;
said annular flat ring having a plurality of spaced apart arcuate slots formed therein;
each spaced apart smooth lug reaching downward through said arcuate slot whereby said outward extending distal ridge at said outer edge of said spaced apart smooth lug cooperatively engages an outer lower edge of said arcuate slot to hold said upper main body securely together with said lower main body; and
said annular flat ring including means for manually rotating said adjustable lock nut.
2. The adjustable lock nut assembly of claim 1 , wherein means for manually rotating said adjustable lock nut comprises a wing extending downward from said annular flat ring.
3. An adjustable lock nut, comprising:
an upper main body and a lower main body;
said upper main body having a circular top surface including an upward extending peripheral ring;
said upper main body includes a plurality of downward extending spaced apart threaded lugs with interior threaded portions facing radially inward for cooperatively engaging a threaded pipe said upper main body including a plurality of downward extending spaced apart smooth lugs, each smooth lug having an outward extending distal ridge extending around an outer edge;
said spaced apart threaded lugs extending from a plurality of corresponding ovoid shaped base members which integrally connect to said upper main body by a connecting portion at one end of said ovoid shaped member rotatably biasing said threaded lugs inwardly for cooperatively engaging said threaded pipe;
said lower main body comprising an annular flat ring having an open center with a cylindrical rim extending downward from a central portion of said annular flat ring;
said cylindrical rim having spaced apart inward facing arcuate shaped ramps each one formed from a wedge shaped step, each arcuate shaped ramp being canted terminating at a distal end by an inward facing lug;
said annular flat ring having a plurality of spaced apart arcuate slots formed therein;
each spaced apart smooth lug reaching downward through said arcuate slot whereby said outward extending distal ridge at said outer edge of said spaced apart smooth lug cooperatively engages an outer lower edge of said arcuate slot to hold said upper main body securely together with said lower main body; and
said annular flat ring including means for manually rotating said adjustable lock nut rotatably biasing and tightening said flat lugs against a threaded pipe.
4. The adjustable lock nut of claim 3 , wherein means for manually rotating said adjustable lock nut comprises a plurality of wings extending outward from said cylindrical rim and downward from said annular flat ring.
5. An adjustable lock nut, comprising:
an upper main body and a lower main body;
said upper main body having a circular top surface including an upward extending peripheral ring;
said upper main body includes a plurality of downward extending spaced apart gripping lugs with interior portions facing radially inward for cooperatively engaging a pipe
said upper main body including a plurality of downward extending spaced apart smooth lugs, each smooth lug having an outward extending distal ridge extending around an outer edge;
said spaced apart gripping lugs extending from a plurality of corresponding ovoid shaped base members which integrally connect to said upper main body by a connecting portion at one end of said ovoid shaped member rotatably biasing said gripping lugs inwardly for cooperatively engaging said pipe;
said lower main body comprising an annular flat ring having an open center with a cylindrical rim extending downward from a central portion of said flat ring;
said cylindrical rim having spaced apart inward facing arcuate shaped ramps each one formed from a wedge shaped step, each arcuate shaped ramp being canted terminating at a distal end by an inward facing lug;
said annular flat ring having a plurality of spaced apart arcuate slots formed therein;
each spaced apart smooth lug reaching downward through said arcuate slot whereby said outward extending distal ridge at said outer edge of said spaced apart smooth lug cooperatively engages an outer lower edge of said arcuate slot to hold said upper main body securely together with said lower main body; and
said annular flat ring including means for manually rotating said adjustable lock nut rotatably biasing and tightening said flat lugs against a pipe.
6. The adjustable lock nut of claim 5 , wherein means for manually rotating said adjustable lock nut comprises a wing extending outward from said cylindrical rim and downward from said annular flat ring.
