Abstract

Abstract A thumb or finger guard formed of resilient rubber or plastic material molded in one piece and providing for dropped curved gripping surfaces on the front portion of the guard. By forming the front portion with thickened material and dropped curved surfaces sharp ridges are provided which will increase the grip upon the surface of the object, such as an apple, potato or carrot, when effecting cutting, tearing or grating of the same. The curvatures, either in single form according to one form of the invention or in multiple and parallel forms, provide for the ridges and for thickened material that will keep the knife or grater from penetrating to any great extent the material of the thumb guard. The guard is cut away at the location of the first knuckle to allow the guard to be more easily flexed and opposing clip formations have been provided for facilitating the insertion of the thumb or finger into the guard or the removal therefrom and at the same time providing for a good gripping action and allowing for further easy flexing of the knuckles of the thumb or finger. Such opposing clip portions are carried on the rear end of a flexible extension leaving the knuckle open except for the very front of the thumb or finger. The knuckle can be worked readily in and between the opposing clip portions.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 118 words
A thumb or finger guard for use in cutting or paring a rounded object formed of molded resilient material comprising a closed end sleeve portion adapted to frictionally grip the thumb or finger when extended thereover and having an integrally-formed thickened work-engaging formation on the front thereof providing for a drop bottom slightly concaved curved surface that nay generally conform to the rounded surface of the object and thickened ridge formations laterally flowing from the concaved curved surface shape and running at their maximum thickness along the side edges thereof whereby to allow upon application of pressure of the guard upon the object surface the flush adaptation of the work engaging surface therewith by the lateral expansion thereof.
Claim 2
Dependent Claim 118 words
A thumb or finger guard for use in cutting or paring a rounded object formed of molded resilient material comprising a closed end sleeve portion adapted to frictionally grip the thumb or finger when extended thereover and having an integrally-formed thickened work-engaging formation on the front thereof providing for a drop bottom slightly concaved curved surface that nay generally conform to the rounded surface of the object and thickened ridge formations laterally flowing from the concaved curved surface shape and running at their maximum thickness along the side edges thereof whereby to allow upon application of pressure of the guard upon the object surface the flush adaptation of the work engaging surface therewith by the lateral expansion thereof.
Claim 3
Dependent Claim 59 words
A thumb or finger guard as defined in claim 1, and an extension running from the front face of the guard rearwardly of the sleeve portion and allowing for open space over the knuckle of the thumb or finger, opposing resilient clip formations carried by the extension rearwardly of the knuckle and adapted to grip the thumb or finger.
Claim 4
Dependent Claim 85 words
A thumb or finger guard as defined in claim 1, and further dropped bottom curved surfaces arranged with the first surface in parallel runs therewith extending longitudinally of the guard over the front thereof and providing for plural dropped curved surfaces running at different radial angles from the closed end of the sleeve portion to provide for different angular engagement with the surface of the object and at the same time to provide plural sharp edge portions to provide for better gripping of the object.
