A binder clip includes a generally triangular clamp including a first side between a mouth and a first vertex, a second side between the mouth and a second vertex, a third side between the first vertex and the second vertex, a first wing extending away from the mouth to a first wing end, and a second wing extending away from the mouth to a second wing end such that the first wing and the second wing are substantially coplanar. The binder clip further includes a first arm pivotably connected to the wing at the first wing end, and a second arm pivotably connected to the wing at the second wing end, the first arm and the second arm cooperatively useable to open the mouth.
1. A binder clip, comprising:
a generally triangular clamp, including:
a first side between a mouth and a first vertex;
a second side between the mouth and a second vertex;
a third side between the first vertex and the second vertex;
a first wing extending away from the mouth to a first wing end;
a second wing extending away from the mouth to a second wing end such that the first wing and the second wing are substantially coplanar;
a first arm pivotably connected to the first wing at the first wing end; and
a second arm pivotably connected to the second wing at the second wing end, the first arm and the second arm cooperatively useable to open the mouth;
wherein the first wing, the second wing, and the third side are substantially parallel.
2. The binder clip of claim 1 , wherein the first side, the second side, the third side, the first wing, and the second wing are contiguously formed from a bent piece of metal.
3. The binder clip of claim 1 , wherein the first arm and the second arm pivot about the first vertex and the second vertex, respectively, to open the mouth.
4. The binder clip of claim 1 , wherein the first arm and the second arm are substantially perpendicular to the first wing, the second wing, and the third side when pivoted against the first vertex and the second vertex.
5. The binder clip of claim 1 , wherein the first arm and the second arm are substantially parallel when pivoted against the first vertex and the second vertex while the mouth is closed.
6. The binder clip of claim 1 , wherein the mouth is biased closed.
7. The binder clip of claim 1 , further comprising a magnet coupled to at least one of the first and second arms.
8. The binder clip of claim 1 , further comprising a suction cup coupled to at least one of the first and second arms.
9. A binder clip, comprising:
a generally triangular clamp, including:
a first side between a mouth and a first vertex;
a second side between the mouth and a second vertex;
a third side between the first vertex and the second vertex;
a first wing extending away from the mouth to a first wing end;
a second wing extending away from the mouth to a second wing end such that the first wing and the second wing are substantially coplanar;
a catch arm pivotably connected to the first wing at the first wing end, the catch arm including a linear segment having a catch width, the linear segment being parallel to the third side and being distal from the clamp; and
a hook arm pivotably connected to the second wing at the second wing end, the hook arm including a hook configured for secure but releasable connection around a linear segment of an identical binder clip, the hook having a hook width less than the catch width of the linear segment;
wherein the hook arm and the catch arm are cooperatively useable to open the mouth.
10. The binder clip of claim 9 , wherein the hook is an S-shaped hook coupled to a distal end of the hook arm.
11. The binder clip of claim 9 , wherein the catch arm is configured to pivot about the first vertex, and
wherein the hook arm is configured to pivot about the second vertex.
12. The binder clip of claim 9 , wherein the hook arm and the catch arm are each pivotable relative to the clamp to cause the hook and catch arms to extend in opposite directions.
13. The binder clip of claim 9 , wherein the catch width is sized to limit sliding of the hook when the hook is connected around the linear segment of the identical binder clip.
14. The binder clip of claim 9 , wherein the hook includes a distal curve distal from the clamp, and the hook is sized such that the connection of the hook around the linear segment of the identical binder clip causes the linear segment of the identical binder clip to contact the distal curve of the hook.
15. The binder clip of claim 9 , wherein the catch arm includes bent wire.
16. The binder clip of claim 9 , wherein the hook arm includes bent wire.
17. The binder clip of claim 9 , wherein the linear segment is a segment of straight wire.
