Abstract

In accordance with this invention, an underside or lower scissors handle, which is conventionally attached to the upper blade of a pair of scissors, is provided with a separate, appropriately sized, additional hole or loop-like band for receiving the index finger of the user. This additional index finger hole is located forward of the main lower finger opening. This unique placement of a separate index finger hole, which is a primary feature of this invention, isolates the index finger against the shaft of the scissors and closer to the pivot point of the blades, and allows the index finger to guide advancing motion of the scissor blades to the right or left as needed to follow a desired path or pattern, for example forming or following a curve. A separate third hole for placement of the index finger makes these scissors unique. Isolating the index finger against the shaft of the scissor handle provides stability and strength and allows the index finger to adjust or “guide” the scissors to the left or right making easy and very subtle adjustments as needed to negotiate curves and angles as in following a pattern. Another feature relates to the “thumb hole” in the upper handle. The inner diameter of such upper handle thumb hole is limited with a suitable restraint, such that the thumb enters only by an amount sufficient to keep the thumb in flexion, and not far enough to place the thumb in extension.

Claims

1. An adaptive scissors comprising an upper blade member and a lower blade member each having a sharpened forward end and a rearward end and pivotally attached to each other for opening and closing motion of the sharpened forward ends of the blades so as to cut material through which the scissors is passed,

handles at the rearward ends of said blades and comprising a lower handle part attached to said upper blade member and an upper handle part attached to said lower blade member, said handle parts being movable toward each other when said blades are closed and moving apart as the blades are separated to be advanced with respect to the material,

said upper handle part having an aperture for reception of the thumb of a user'"'"'s hand,

said lower handle part having an elongated aperture of generally oval shape to receive at least one finger of the user'"'"'s hand other than the index finger, and

a smaller secondary aperture on said lower handle part at the front of said lower handle part providing a separate locating aperture for surrounding the index finger of the user'"'"'s hand to train the user to place the index finger of his/her hand forward of the lower handle part into which the other fingers are placed, and thus to enhance guidance of the scissors as it is moved forward through material being cut.

2. A scissors as defined in claim 1, further comprising

a stop member located in said upper handle aperture to limit the extension of a user'"'"'s thumb into said upper handle aperture.

3. A scissors as defined in claim 1, further comprising

a flexible band secured to said lower handle part as a loop at the front thereof to define said separate locating aperture.

4. A scissors comprising an upper blade and a lower blade,

pivot means connecting said blades for opening and closing motion so as to cut material positioned between said blades,

said blades having forward tips which can be closed and opened forward of said pivot means,

a handle at the rear end of said blades comprising a lower handle part attached to said upper blade and an upper handle part attached to said lower blade, both said handle parts extending rearward from said pivot means,

said upper handle part having an aperture for reception of the thumb of a user.

said lower handle part having an elongated aperture of generally oval shape and also including a flattened interior surface in the region where the handle parts come together when the blades are closed, and

a smaller secondary aperture defined by a generally oval band extending from the exterior forward sides of said lower handle part and providing a separate locating aperture for the index finger of the user so as to isolate the index finger against the side of the scissors and close to the pivot point of the blades, allowing the index finger to guide the scissor blades to the right or left as needed to follow a desired path.

5. A scissors as defined in claim 4, further comprising said upper handle aperture being sized to limit the extension of a thumb into said upper handle aperture.

6. A scissors as defined in claim 5, wherein a stop member is located in said upper handle aperture to limit the size of the passage therethrough.

7. A scissors as defined in claim 4, further comprising

said band defining said separate locating aperture is a flexible member which can be adjusted in length to provide a control of the aperture size of said separate locating aperture.
