Abstract
A single paper clip is capable of separately holding two different sheafs of papers. It is formed of a continuous length of wire successively bent into a series of re-entrant loops interspersed with six legs. One sheaf of papers may be secured between a first and third loop, and a second sheaf is thereafter secured between a third and fifth loop.
Claims7
A paper clip, composed of a continuous length of wire multiply bent re-entrantly to define a plurality of loops, formed to comprise:
- a first leg of said wire continuing in a first direction from one end of said wire a first distance;
- a first re-entrant curved loop of said wire continuing from said first leg;
- a second leg of said wire continuing from said first loop a second distance in a second direction opposite said first direction;
- a second re-entrant curved loop of said wire continuing from said second leg;
- a third leg of said wire continuing from said second loop a third distance in said first direction;
- a third re-entrant curved loop of said wire continuing from said third leg;
- a fourth leg of said wire continuing from said third loop a fourth distance in said second direction;
- a fourth re-entrant curved loop of said wire continuing from said fourth leg;
- a fifth leg of said wire continuing from said fourth loop a fifth distance in said first direction;
- a fifth re-entrant curved loop of said wire continuing from said fifth leg;
- a sixth leg of said wire continuing from said fifth loop a sixth distance in said second direction;
- said second distance being greater than said first distance, said third distance being less than said second distance, said fourth distance being less than said third distance, said fifth distance being less than said fourth distance, and said sixth distance being less than said fifth distance.
