  "abstract": "The locking nut and bolt system utilizes a bolt with thread having a plurality of notches generally longitudinally spaced in a predetermined pattern. Each notch has a lock face and an opposing slope. The locking unit carries one or more tines. The tine has a distal tine end adapted to latch onto the lock face of the notch on the bolt and, when the distal tine end is not disposed in one or more notches, the tine end moves on the bolt thread crest. When the distal tine end is in the notch or notches, the lock face of the notch prevents counter-rotational movement of the bolt with respect to the nut when the distal tine end abuts the lock face. The locking unit supports the tine and may be cylindrical, rectangular or on a perpendicular support face normal to a radial plane through the axial centerline of the nut thread. The locking unit may be on a nut insert or may be carried on the leg of a U, J or S-shaped clip. The locking unit may be recessed as a blind hole.",
  "claims": [
    "1. An S-shaped locking nut and bolt assembly for a bored panel comprising: an elongated bolt having a stem and a bolt thread on said stem, said bolt thread defining bolt thread crest and bolt thread troughs, said bolt having a plurality of notches defined on said bolt thread generally longitudinally in a predetermined pattern with proximal notches being longitudinally adjacent each other on said bolt thread, each notch having a lock face and an opposing slope on said bolt thread which form a locking channel on said stem; an S-shaped member having first, second and third elongated, generally planar legs; a nut formed on one of said second and said third legs, said nut having a nut thread about an axial centerline which is complementary to said bolt thread; a locking element formed on the other of said second and third legs, said locking element having a locking element bore coaxial with respect to said axial centerline, said locking element having a plurality of axially protruding legs perpendicular to said planar other leg and having a corresponding plurality of tines, each tine protruding tangentially and radially inward toward said axial centerline, said axially protruding legs depending from said planar other leg, each said tine having a distal tine end adapted to latch on said lock face of said notch and a proximal tine portion attached to said corresponding axially protruding leg; said S-shaped member adapted to be mounted on said panel with said axial centerline of said nut, said panel bore and said locking element bore being substantially coaxially aligned; one of said plurality of distal tine ends being adapted to move radially inward when said distal tine end is disposed in one or more notches and move radially outward when said distal tine end rides on said bolt thread crest, and the position of said distal tine end being visible due to the disposition of said elongated locking element on said third leg.",
    "2. A locking nut and bolt assembly as claimed in claim 1 wherein said plurality of tines are disposed circumferentially about said locking element bore.",
    "3. An S-shaped locking nut assembly for a bored panel and an elongated bolt having a stem and a bolt thread on said stem, said bolt thread defining bolt thread crest and bolt thread troughs, said bolt having a plurality of notches defined on said bolt thread generally longitudinally in a predetermined pattern with proximal notches being longitudinally adjacent each other on said bolt thread, each notch having a lock face and an opposing slope on said bolt thread which form a locking channel on said stem, said locking nut assembly comprising: an S-shaped member having first, second and third elongated, generally planar legs; a nut formed on one of said second and said third legs, said nut having a nut thread about an axial centerline which is complementary to said bolt thread; an elongated locking unit formed on the other of said second and said third legs, said locking unit formed as a cylinder with its cylindrical axis perpendicular to the plane of said other leg, said locking unit having at least one tine protruding tangentially and radially inward toward said cylindrical axis, said tine having a distal tine end adapted to latch on said lock face of said notch and a proximal tine portion adjacent said cylinder, said cylinder defining a cut-out at said tine; said S-shaped member adapted to be mounted on said panel with said axial centerline of said nut, said panel bore and said cylindrical axis of said locking unit being substantially coaxially aligned; said distal tine end being adapted to move radially inward when said distal tine end is disposed in one or more notches and move radially outward when said distal tine end rides on said bolt thread crest, and the position of said distal tine end being visible due to the disposition of said elongated locking unit on said other leg.",
    "4. A locking nut assembly as claimed in claim 3 wherein said cylinder carries a plurality of tines protruding tangentially and radially toward said axial centerline, said plurality of tines disposed circumferentially about said cylinder.",
    "5. An S-shaped locking nut assembly for a bored panel and an elongated bolt having a stem and a bolt thread on said stem, said bolt thread defining bolt thread crest and bolt thread troughs, said bolt having a plurality of notches defined on said bolt thread generally longitudinally in a predetermined pattern with proximal notches being longitudinally adjacent each other on said bolt thread, each notch having a lock face and an opposing slope on said bolt thread which form a locking channel on said stem, said locking nut assembly comprising: an S-shaped member having first, second and third elongated, generally planar legs; a nut formed on one of said second and said third legs, said nut having a nut thread about an axial centerline which is complementary to said bolt thread; a locking element formed on the other of said second and said third legs, said locking element having a locking element bore coaxial with respect to said axial centerline, said locking element having a plurality of axially protruding legs perpendicular to said planar other leg and having a corresponding plurality of tines, each tine protruding tangentially and radially inward toward said axial centerline, said axially protruding legs depending from said planar other leg, each said tine having a distal tine end adapted to latch on said lock face of said notch and a proximal tine portion attached to said corresponding axially protruding leg; said S-shaped member adapted to be mounted on said panel with said axial centerline of said nut, said panel bore and said locking element bore being substantially coaxially aligned; one of said plurality of distal tine ends being adapted to move radially inward when said distal tine end is disposed in one or more notches and move radially outward when said distal tine end rides on said bolt thread crest, and the position of said distal tine end being visible due to the disposition of said elongated locking element on said other leg.",
    "6. A locking nut assembly as claimed in claim 5 wherein said plurality of tines are disposed circumferentially about said locking element bore."

  "description_excerpt": "The present application is a continuation-in-part of U.S. patent application Ser. No. 08/747,323 filed Nov. 12, 1996, now pending, which claims the priority of provisional patent applications Ser. Nos. 60/015,230 and 60/015,980, respectively filed on Apr. 10, 1996 and Apr. 15, 1996, and the present application is also based upon and claims the benefit of provisional patent application Ser. No. 60/050,487, filed on Jun. 23, 1997.\n\nU.S. Pat. No. 307,722 to Klemroth discloses a bolt A with longitudinal channel D running through the crest of the threads. The nut has a tine extending above a flat end surface of the nut. The tine pops into and out of channel D. U.S. Pat. No. 591,062 to Smith discloses a bolt with a longitudinal channel which enables a chisel to be placed in a slot in a nut block and further to stop rotation of the bolt with respect to the block. U.S. Pat. No. 1,088,892 to Foreman discloses a screw with a longitudinal channel extending through the threads of the bolt. The tine is located outside of the nut threads. U.S. Pat. No. 1,136,310 to Burnett discloses small notches cut in the top of the crest ofthe bolt threads. The notches define radially aligned surfaces. A flexible tine in the interior of the nut moves in and out of the small notches. The tine is inserted in a tangential cavity in the nut. U.S. Pat. No. 1,211,194 to Lang discloses what appears to be a bolt with longitudinal channels on its threads. A sheet steel spring is wrapped around an exterior portion of the nut and a portion of the spring is generally radially inserted through the nut to lock into the bolt channels. U.S. Pat. No.",
