Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
224 words
A handle with an interchangeable kitchen implement, comprising: an elongate handle adapted to selectively mount one of a plurality of implements, said handle having opposed forward and rear ends, upper and lower surfaces, and opposed elongate side edges, a hollow chamber defined within said handle and having an open end opening through said forward end of said handle, a pair of recesses, one in each of said opposed side edges, in closely spaced relation to said forward end of said handle, and an aperture defined in each recess and opening into said chamber to form a locking component for a chamber-received implement; and an implement having a central body, a working portion fixed to and extending forwardly from said body, a rear mounting portion receivable in said handle chamber, and a rearwardly directed extension on said body rigidly joining said mounting portion to said body, said mounting portion including an elongate stem extending rearwardly from said body extension and terminating in a transverse head, said head having opposed ends integral with a pair of forwardly extending laterally spaced locking legs extending parallel to and spaced from said stem, each leg having a forward end with an integral locking protuberance extending laterally outward of the corresponding leg for reception within an aligned one of said recesses upon reception of said mounting portion in said chamber.
Claim 2
Dependent Claim
224 words
A handle with an interchangeable kitchen implement, comprising: an elongate handle adapted to selectively mount one of a plurality of implements, said handle having opposed forward and rear ends, upper and lower surfaces, and opposed elongate side edges, a hollow chamber defined within said handle and having an open end opening through said forward end of said handle, a pair of recesses, one in each of said opposed side edges, in closely spaced relation to said forward end of said handle, and an aperture defined in each recess and opening into said chamber to form a locking component for a chamber-received implement; and an implement having a central body, a working portion fixed to and extending forwardly from said body, a rear mounting portion receivable in said handle chamber, and a rearwardly directed extension on said body rigidly joining said mounting portion to said body, said mounting portion including an elongate stem extending rearwardly from said body extension and terminating in a transverse head, said head having opposed ends integral with a pair of forwardly extending laterally spaced locking legs extending parallel to and spaced from said stem, each leg having a forward end with an integral locking protuberance extending laterally outward of the corresponding leg for reception within an aligned one of said recesses upon reception of said mounting portion in said chamber.
