Abstract
Embodiments are disclosed that relate to binder clips. For example, one disclosed embodiment provides 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, 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 comprises 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.
Claims20
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;
- 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;
- 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.
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;
- and
- a third side between the first vertex and the second vertex;
- a hook arm pivotably connected to the clamp, the hook arm configured to hook a catch arm of another binder clip;
- and
- a second arm pivotably connected to the clamp, wherein the hook arm and the second arm are cooperatively useable to open the mouth.
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;
- and
- a third side between the first vertex and the second vertex;
- a first arm pivotably connected to a first hinge of the generally triangular clamp such that the first arm pivots about a first pivot axis of the first hinge;
- and
- a second arm pivotably connected to a second hinge of the generally triangular clamp such that the second arm pivots about a second pivot axis of the second hinge, the first pivot axis and the second pivot axis being substantially parallel, at least the first hinge having three troughs, each trough separated from an adjacent trough by a crest, the troughs and crests cooperatively configured such that, as the first arm pivots to approach a middle trough, an angular position of the first arm is increasingly biased toward stopping in the middle trough, and as the first arm pivots to approach a crest, the first arm is increasingly biased toward returning to the middle trough until surmounting the crest, the first arm changing bias to an adjacent trough on another side of the crest once having surmounted the crest.
