Abstract
A lug nut is formed with a threaded bore (29) and a lug socket (25) for receipt of a square drive (27)for driving of the lug nut.
Claims
1. A lug nut apparatus for use with a conventional drive tool having a drive lug with a predetermined square cross section, said apparatus comprising: a wheel formed with a plurality of lug nut bores for fitting in close spaced relationship over the lug studs of a wheel hub and respective axially outwardly facing peripheral wheel chamfers; a plurality of lug nuts formed with cylindrical peripheral surfaces and terminating on their respective axial inner ends with respective nut chamfers configured to complementally abut the respective said wheel chamfers-, and said lug nuts being further formed in their respective axial outer extremities with axially outwardly opening square lug sockets of said predetermined square cross section configured for complemental free telescopieal receipt of said drive lug whereby said lug nuts may be screwably threaded out the respective said studs and said conventional drive tool positioned to selectively engage said lug in the respective said sockets so that rotation of said tool will cause said lug to rotate said lug nuts on the respective studs.
2. Lug nut apparatus as set forth in claim 1 for alternative use with a conventional lug nut wrench configured with conventional hexagonal socket and including: an elongated adapter including a square cross section adaptor lug configured for complemental fitting m said lug sockets and projecting axially outwardly therefrom to form a hexagonal boss for receipt in said conventional hexagonal socket.
3. Lug nut apparatus as set forth in claim 2 for use with either said first or a second conventional lug nut wrench formed with respective first and second hexagonal sockets of a first cross section and second smaller cross section, respectively, and wherein: said adapter includes a first boss formed with a first hexagonal cross section to complementally receive said first hexagonal socket and a second boss axially distal of said first boss and configured for complemental receipt thereover of the said second hexagonal socket. 1 3
4. Lug nut apparatus as set forth in claim 1 wherein: said lug nuts are formed with said lug nut sockets configured with a cross section having an eight point polygonal shape configured to receive said square lug oriented in two different relative positions.
5. Lug nut apparatus as set forth in claim I wherein: said lug nuts are formed with said lug nut sockets to receive said square lugs configured with one-half inch square cross section.
6. Lug nut apparatus as set forth in claim 1 wherein: said lug nuts are formed with respective cylindrical peripheral walls.
7. Lug nut apparatus as set forth in claim 1 for use with a three-eighths inches square solid drive lug, and wherein: said lug nuts are formed with said lug nut sockets substantially three-eighths inches square, open cross section, and sized to receive said square lugs.
8. Lug nut apparatus as set forth in claim 1 wherein: said plurality of lug nuts comprises a set of said lug nuts consisting of one said lug nut for each and every said lug stud on said wheel.
9. Lug nut apparatus as set forth in claim I wherein: said lug nuts are formed with said lug sockets configured with a selected depth and are of a constant cross section throughout said depth.
10. A lug nut apparatus to be driven by a wrench having a conventional square cross section solid lug and configured for receipt on a threaded lug stud to cooperate in mounting a wheel of the type formed with a lug bore for receipt of said lug stud and formed with an outwardly facing wheel chamfer, said lug nut comprising: 14
a cylindrical body formed with an internally threaded bore opening to one end for tlu-eaded receipt on said stud and further formed at said one end with a radially and axially outwardly tapered chamfer for abutting said wheel chamfer; and said body further formed with an axially outwardly opening lug socket configured with a square cross section to complementally receive said square lug.
11. Lug nut apparatus as set forth in claim 10 wherein: said lug sockets is configured with a three-eighths inch square cross-section.
12. Lug nut apparatus as set forth claim 10 wherein: said body is formed with said axially outwardly opening lug socket configured with a cross section having an eight point polygonal shape configured to receive a square drive lug.
13. Lug nut apparatus as set forth in claim 10 wherein: said body is formed with a through axial passage defining said socket projecting axially distal of said threaded bore.
14. Lug nut apparatus as set forth in claim 12 wherein: said socket is formed on its lateral opposite sides with facets projecting parallel to one another.
15. A wheel lug nut to be driven by a wrench having a conventional square cross section solid lug and configured for receipt on a threaded lug stud to cooperate in mounting a wheel of the type formed with a lug bore for receipt of said lug stud and formed with an outwardly facing wheel chamfer, said lug nut comprising: a cylindrical body formed with a through axial opening having an axial inner section and an axial outer section, said body being formed in said axial inner section with one-half inch diameter threaded bore opening for threaded receipt on said stud; said body being further formed at its axially inner end with a radially and axially outwardly tapered chamfer for abutting said wheel chamfer; and 15
said body even further formed at said axial outer section with an axially outwardly opening eight point star shaped lug socket configured with two interposed square cross sections rotated about the axis of said lug 45 " to one another to complementally receive said solid square lug in two different positions.
16. A wheel lug nut according to claim 15 wherein: said body is formed with said socket configured with corners at the distal tip of the respective said square cross sections in said socket and further formed at said comers with axially projecting semi-cylindrical cut outs.
17. A lug nut as set forth in claim 16 wherein: said cut outs are formed with respective radii of between .532 and .538 inches.
18. Lug nut apparatus as set forth in claim 12 wherein: said apparatus comprises a plurality of said sets consisting of on said set for each and every said wheel on a vehicle.
19. Lug nut apparatus as set forth in claim 12 wherein: said body is configured with a selecte depth and is of a constant cross section throughout said depth.
20- Lug nut apparatus as set forth in claim 12 wherein: said socket is formed on its lateral opposite sides with facets projecting parallel to one another.
