Abstract
A cotter formed from a single piece of wire including a free end, first and second gripping portions, a helical section and a locking leg. The cotter may be installed on a pin having an opening by grasping either, oppositely disposed gripping portion. The arrangement of the locking leg and a helical section formed therein allows for easy installation but requires a compound motion for removal of the cotter.
Claims15
A coplanar bow tie locking cotter for a pin comprising:
- a continuous piece of wire stock having overlapping first and second ends;
- said wire stock having first and second similarly configured, oppositely disposed arcuate loops with gripping sections;
- a helical section of said wire stock integrally formed between said arcuate loops;
- a first section being bent in a gradual reversed arc and adjoining said first end and an end of said a first arcuate loop, said first arcuate loop forming the first arcuate gripping section;
- said second end extending in a direction of said first arcuate loop and being located between said first end and said helical section adjacent said first section.
A coplanar bow tie locking cotter for a pin comprising:
- a continuous segment of wire stock having a first end and a locking end;
- said continuous segment of wire stock having a pair of similarly configured, oppositely disposed arcuate loops, said loops including at least one gripping portion;
- a helical section of said wire stock formed between said pair of arcuate loops;
- a first section adjoining said first end and one of said arcuate loops;
- wherein said locking end extends in a direction of said one of said arcuate loops and is located between said first end and said helical section adjacent said first section;
- and
- said locking end adopted to abut said pin in a locked condition when said cotter is received by said pin.
A coplanar bow lock hairpin cotter formed from a single piece of wire stock having first and second substantially similarly configured, oppositely disposed, gripping portions and a free end for attachment through an opening formed in a pin, said cotter comprising:
- a first section for being received in said opening, said first section being bent in a gradual reversed arc and adjoining a first end of a first arcuate loop, said first arcuate loop forming the first gripping portion;
- a second end of the first arcuate loop transgressing adjacent the first section and terminating in a second arcuate loop;
- said second arcuate loop forming the second gripping portion and terminating at a wire end wherein said wire end extends in a direction of said first arcuate loop and is located between said first end and said second end of said first arcuate loop and adjacent said first section;
- and
- said wire end adapted to substantially abut said pin in a locked condition when said cotter is received with said pin opening.
A coplanar bow tie locking cotter for a pin having an opening, the coplanar bow tie locking cotter comprising:
- a single piece of formed wire having a first end, a first arcuate bend, a helical section, a second arcuate bend, and a locking end;
- the first end disposed for being received in the pin opening;
- the helical section being formed between the first and second arcuate bends for partially encapsulating the pin a first section adjoins said first end and said first arcuate bend;
- the first and second arcuate bends being substantially similarly configured;
- and
- the locking end being positioned adjacent said first section between the first end extending in a direction of said first arcuate bend and and the helical section for positively locking the cotter on the pin.
