Abstract

The present invention is a scissor assembly adapted to be in an open or closed position and to be manipulated by a user to cut a selected material. The scissors assembly includes a first scissors member and a second scissors member pivotally connect and biased into the open position. The first scissor member has a handle and a blade. The first handle is formed as an enlarged and elongated shaft sized to fit in a user's palm and be gripped by the fingers, the second scissor member likewise, has a handle and a blade. The second handle has a portion which defines a lever sized to be manipulated by the thumb when the first handle portion is fit in the user's palm and gripped by the user's fingers. In the preferred embodiment, the first handle is formed as a releasable container and the second handle is foreshortened relative to the first handle. In the alternative embodiments, the first handle is formed of implements such as a screw-driver, flashlight or pliers. The scissor assembly can also include a locking assembly to retain the closed position of the blades and a limit stop to limit the distance between the open position.

Dependent claims

A scissor assembly adapted to be manipulated by a user to cut a selected material comprising:

a first scissor member including a first handle portion and a first blade portion extending forwardly of said first handle portion to terminate at a first distal tip, said first handle portion formed as an enlarged and elongated shaft sized to fit in a user's palm and be gripped therearound in a held position by the fingers;
a second scissor member including a second handle portion and a second blade portion extending forwardly of said second handle portion to terminate at a second distal tip, said second handle portion being formed as a relatively flat platform having an upper surface, a lower surface and a thickness therebetween, said platform having a length in a longitudinal direction and a width transverse to the longitudinal direction that is greater than the thickness thereof so that the width of said platform projects laterally of the longitudinal direction to define a plate-like lever sized to be manipulated by the thumb when positioned on the upper surface of said platform and when the first handle portion is fit into the user's palm and gripped by the user's fingers;
a pivot means for pivotally connecting said first and second scissor members at a pivot location whereby said first and second scissor members are movable between an open position wherein said first and second scissor members are orientated transversely to each other whereby said material may be received therebetween, and a closed position wherein said first and second scissor members are oriented alongside one another, said second handle being oriented so that it is at an acute angle to the first handle when in the open position and moves into an orientation laterally adjacent said elongated shaft when in the closed position;
and
biasing means for biasing said first and second scissor members toward the open position.

A scissors assembly adapted to be manipulated by the user's thumb and palm and fingers of one hand for cutting a selected material, comprising:

a first scissor member including a first handle portion and a first blade portion having a first inner surface, said first blade portion extending forwardly of said first handle portion to terminate at a first distal tip;
a second scissor member including a second handle portion and a second blade portion having a second inner surface, said second blade portion extending forwardly of said second handle portion to terminate at a second distal tip, said second handle portion formed as a lever;
a pivotal means for pivotally connecting said first and second scissor members at a pivot location whereby said first inner surface and second inner surface are oriented to face one another, and said first and second scissor members are movable between an open position wherein said first and second scissor members are oriented transversely to each other and a closed position wherein said first and second scissor members are oriented alongside one another;
limiting stop means located on said first and second inner surfaces for limiting the spaced apart orientation between said first scissor member and said second scissor member in the open position;
biasing means for biasing said first and second scissor members toward the open position;
and
said first scissor member having a first cavity at the pivot location and said second scissor member having a second cavity opposed to said first cavity at the pivot location, said first cavity and second cavity registering with one another when said first and second scissor members are pivotally connected to form a chamber operative to receive said biasing means.
