Abstract
A locking system for use with a wheeled vehicle such as a bicycle is described. The system is useful either to lockingly secure a wheel to the fork members of a bicycle or to lockingly secure the seat post to the center frame member. The locking member is cylindrical in shape and covers a specially configured nut that replaces the usual lever operated nut used with a spindled axle system.
Claims19
A system for lockingly affixing a removable component between a bifurcated portion of a wheeled vehicle comprising:
- shaft means for passing between the bifurcated portion of the wheeled vehicle, said shaft means defining a bore therethrough;
- spindle means for passing through said shaft means bore, the spindle means having an integrally formed enlarged end, said enlarged end formed to receive a wrench capable of turning said spindle means and said spindle means further defining a threaded end distal of said enlarged end;
- a lug threadably engageable with said spindle means threaded end, said lug defining engagement means for engaging said bifurcated portion whereby said lug becomes non-removable when said spindle means is passed through said shaft means bore and when said spindle means is threadably engaged therewith;
- and
- cylindrically shaped lock means for rotatably covering said enlarged end while said spindle means is passed through said shaft means and said lug is engaged with said bifurcated portion.
The system of claim wherein the bifurcated portion of the wheeled vehicle is a front fork of a bicycle, said front fork adapted to slidingly receive said shaft means, and wherein the lug is generally conical in shape and said engagement means is formed to engage at least one tine of said fork.
The system of claim wherein the bifurcated portion of the wheeled vehicle is a front fork of a bicycle, said front fork adapted to slidingly receive said shaft means, and wherein the lug is generally conical in shape and said engagement means is formed to at least partially overlay at least one tine of said fork.
A wheel securing system for a bicycle, the bicycle having front and rear wheel mounting forks, the wheels being mountable therebetween with their respective axles, said axles each defining an axial bore therethrough;
- the securing system comprising:
- spindle means for passing through said shaft means axial bore, said spindle means having an integrally formed enlarged end, and said spindle means further defining a threaded end distal of said enlarged end;
- a lug threadably engageable with said spindle threaded end, said lug defining engagement means for engaging said bifurcated portion whereby said lug becomes non-removable when said spindle means is passed through said shaft means bore and when said spindle manes is threadably engaged therewith;
- and
- cylindrically shaped lock means for rotatably covering said enlarged end while said spindle means is passed through said shaft means and said lug is engaged with said bifurcated portion.
A bicycle seat securing system, the bicycle having a bifurcated center frame member, the bicycle seat being affixed to a seat post which is mountable in said center frame member, said center frame member including outwardly extending ears from said bifurcated portion each defining coaxial bores;
- the securing system comprising:
- spindle means for passing through said coaxial bores, said spindle means having an integrally formed enlarged end, and said spindle means further defining a threaded end distal of said enlarged end;
- a lug threadably engageable with said spindle threaded end, said lug defining engagement means for engaging said ears whereby said lug becomes non-removable when said spindle means is passed through said coaxial bores and when said spindle manes is threadably engaged therewith;
- and
- cylindrically shaped lock means for rotatably covering said enlarged end while said spindle means is passed through said coaxial bores and said lug is engaged with said bifurcated portion.
