Abstract

A tool for removing ticks and similar parasites. A spoon-shaped tool, the spoon of which is split lengthwise and hinged to rotate the split spoon sections normally open far enough to fit over a tick'"'"'s body, then rotated closed into an overlapping relationship by thumb and forefinger closing pressure to trap the tick about the neck in a v-shaped slit in one side of the opening in the spoon. A mechanical stop prevents the slit from closing completely to sever the tick from it'"'"'s head. The handle may have a centerline hinge, integral spring, and thumb and finger locators to facilitate use of the tool in a palm-down fashion by either hand. The spoon sections may have opposing slits that close upon each other to likewise trap the tick. The tick is at all times visible in the open bowl of the tool. The tool may be molded in one piece, with a "living hinge" and spring incorporated into it'"'"'s design.

Claims

1. A tool for removing ticks and similar parasites, comprising

a handle,

two spoon-shaped sections,

means by which said sections are hingedly attached on an axis parallel to said handle so as to be rotatable between an open position and a closely-fitting overlapping closed position, and

a mechanical stop determining said closed position,

the first of said sections having an open slit in one edge, said slit being first closed and then reduced in size by the second of said sections as said sections are rotated from said open position to said overlapping closed position.

2. The tool of claim 1, said tool configured with at least one spring configured to normally maintain said sections in said open position and resist rotation towards said overlapping closed position.

3. The tool of claim 1, said tool configured with at least one spring configured to normally maintain said sections in said overlapping closed position and resist rotation towards said open position.

4. The tool of claim 2, wall of said slit being tapered to provide a thin interfacing edge to said second of said sections in said overlapping closed position.

5. The tool of claim 2, said handle comprising left and right side components, each of said components attached to a respective said section and being rotatable therewith.

6. The tool of claim 5, said left and right side components incorporating opposing thumb and finger locators, said locators being interchangeably usable by left and right hands.

7. The tool of claim 6, said means by which said sections are hingedly attached comprising a centerline hinge connecting said left and right side components of said handle.

8. The tool of claim 7, said spring installed in a spring recess in said handle.

9. The tool of claim 7, wherein said left and right side components, said centerline hinge, and said spoon-shaped sections are produced as a one piece molding.

10. The tool of claim 7, wherein said left and right side components, said centerline hinge, said spoon-shaped sections, and said spring are produced as a one piece molding.

11. A tool for removing ticks and similar parasites, comprising

a handle,

two spoon-shaped sections,

means by which said sections are hingedly attached on an axis parallel to said handle so as to be rotatable between an open position and a closely-fitting overlapping closed position, and

a mechanical stop determining said closed position,

the first of said sections having a slit in one edge, said slit being first closed and then reduced in size by the second of said sections as said sections are rotated from said open position to said overlapping closed position,

said tool configured with at least one spring configured to normally maintain said sections in said open position and resist rotation towards said overlapping closed position,

wall of said slit being tapered to provide a thin interfacing edge to said second of said sections in said overlapping closed position,

said handle comprising left and right side components, each of said components attached to a respective said section and being rotatable therewith,

said left and right side components incorporating opposing thumb and finger locators, said locators being interchangeably usable by left and right hands,

said means by which said sections are hingedly attached comprising a centerline hinge connecting said left and right side components of said handle,

said spring configured in a spring recess in said handle,

wherein said left and right side components, said centerline hinge, said spoon-shaped sections, and said spring are produced as a one piece molding.
