Rotating eye bolt assembly with lock mechanism
A rotating eye bolt assembly with lock mechanism. The assembly includes a threaded bolt having a multi-sided head. A lifting bail includes a pair of opposed legs, a track and a central opening through the track. A bushing having an upstanding cylindrical lip is received in the lifting bail central opening. A lock plate is slidable on the track with the lock plate having an upstanding shoulder engageable with the bolt head. The lock plate is movable between a locked position for installation and removal of the assembly and an unlocked position for use of the assembly.
1. A rotating eye bolt assembly with lock mechanism, which assembly comprises:
a bolt having a multi-sided head;
a lifting bail with a flat track and a central opening through said flat track configured to receive said bolt;
a bushing having an upstanding cylindrical lip, said bushing receivable in and through said lifting bail central opening; and
a lock plate having a top surface and an opposed substantially flat bottom surface, said bottom surface slidable on said track, said lock plate having a pair of opposed ends with an upstanding shoulder at one of said ends engageable with said bolt head, having an elongated slot through said lock plate and having at least one retaining spring, wherein said lock plate and said track are configured so that said head of said bolt rests on said top surface of said lock plate;
wherein said lock plate is slidable on said track between a locked position and an unlocked position such that:
in the locked position, said upstanding shoulder is engaged with said bolt head to prevent rotation of said lifting bail with respect to said bushing; and
in the unlocked position, said upstanding shoulder is disengaged from said bolt head such that said lifting bail is rotatable with respect to said bushing.
2. A rotating eye bolt assembly with lock mechanism as set forth in claim 1 wherein said lifting bail has a pair of opposed walls which constrain movement of said lock plate on said track.
3. A rotating eye bolt assembly with lock mechanism as set forth in claim 1 wherein said bolt has a circumferential groove and wherein a removable clip is receivable in said groove.
4. A rotating eye bolt assembly with lock mechanism as set forth in claim 1 wherein said at least one retaining spring comprises a pair of retaining springs.
5. A rotating eye bolt assembly with lock mechanism as set forth in claim 4 wherein each of said pair of retaining springs extends from said lock plate into an opening in said upstanding cylindrical lip of said bushing.
6. A rotating eye bolt assembly with lock mechanism as set forth in claim 1 wherein said bolt has a shaft having an axis and wherein said track is perpendicular to said bolt axis.
7. A rotating eye bolt assembly with lock mechanism as set forth in claim 1 wherein said bolt has a hexagon head.
