Abstract
A multi-attachment lever binder with a lever having a first and second bifurcated arm mounted thereon. The first bifurcated arm is mounted on the lever to establish a first pivot point. The second bifurcated arm is mounted on the lever to establish a second pivot point. The ends of the first and second bifurcated arms disposed opposite from the pivot points may be joined together to form a cavity for retaining the end of a connection device. The second pivot point is configured to move in an arc centered about the first pivot point as the lever is moved from an open position to a binding position.
Claims19
A multi-attachment lever binder, comprising:
- a lever having a first end configured to provide a handle and a second end disposed opposite the first end;
- a first bifurcated arm having a first end and a second end disposed opposite from the first end, the first bifurcated arm having a pair of arm members configured to pivotally mount on the outside of the lever to form a first pivot point between the first bifurcated arm and the lever, the pair of arm members configured to attach to a connection device, the first bifurcated arm curved or angled between the first end and the second end;
- a second bifurcated arm having a first end and a second end disposed opposite from the first end, the arm having a pair of arm members configured to pivotally mount on the outside of the lever to form a second pivot point between the second bifurcated arm and the lever, the pair of arm members configured to attach to a connection device at, the second bifurcated arm curved or angled between the first end and the second end;
- wherein the second pivot point is configured to move in an arc centered about the first pivot point as when the lever is moved from an open position to a binding position;
- and,
- wherein the pair of arm members on the first bifurcated arm extend inward toward each other at the second end of the first bifurcated arm and are configured to attach to each other at the second end of the first bifurcated arm to define a unitary structure having a round opening at one end and a cavity defined therein for rotatably receiving at least a portion of the connection device, the cavity having a width greater than the opening such that the at least a portion of the connection device is captured in the cavity and prevented from exiting in the axial direction through the opening.

A multi-attachment lever binder, comprising:
- a lever having a first end configured to provide a handle and a second end disposed opposite the first end, the lever having a first pair of trunnions extending from opposite sides of the lever toward the second end and a second pair of trunnions extending from opposite sides of the lever disposed in spaced apart relation to the first pair of trunnions;
- a first bifurcated arm having a first end and a second end disposed opposite from the first end, the first bifurcated arm having a pair of arm members, each arm member having an opening at the first end configured to mount on one of the trunnions on the lever to form a first pivot point where the first bifurcated arm attaches to the lever, the pair of arm members curved or angled between the first end and the second end;
- a second bifurcated arm having a first end and a second end disposed opposite from the first end, the arm having a pair of arm members, each arm member having an opening at the first end configured to mount on one of the trunnions on the lever to form a second pivot point where the second bifurcated arm attaches to the lever, the pair of arm members curved or angled between the first end and the second end;
- wherein the second pivot point is configured to move in an arc centered about the first pivot point as the lever is moved from an open position to a binding position;
- and,
- wherein the pair of arm members on the first bifurcated arm extend inward toward each other at the second end of the first bifurcated arm and are configured to attach to each other at the second end of the first bifurcated arm to define a unitary structure having a round opening at one end and a cavity defined therein for rotatably receiving at least a portion of the connection device, the cavity having a width greater than the opening such that the at least a portion of the connection device is captured in the cavity and prevented from exiting in the axial direction through the opening.
