ABSTRACT:

TECHNICAL FIELD OF THE INVENTION
This invention relates to a protective sleeve for the blade of a knife or a similar implement.
BACKGROUND OF THE INVENTION
Various types of sleeves have been used to cover the blades of implements such as knives or the like including sleeves which have included cooperating, interconnected sections. Although these sleeves have been satisfactory, there remains a need for a sleeve in which the cooperating sections can be easily and quickly interconnected and assembled at either the point of manufacture or the point of purchase.
SUMMARY OF THE INVENTION
The subject invention relates to a new and useful sleeve including respective halves incorporating coupling elements which allow the sleeve to be easily and quickly assembled either at the point of manufacture or at the point of purchase.
In accordance with the present invention, the sleeve includes first and second coupled half sections each including top and bottom peripheral edges and a unitary distal peripheral edge which together define a sleeve with top and bottom peripheral surfaces, a distal peripheral surface defining a closed end, and an opposed open proximal end through which the blade of the knife is received.
The first and second sections respectively include a plurality of clips and associated cut-outs extending along the respective top, bottom and distal peripheral edges in spaced-apart relationship for coupling and snapping the first and second sections together.
In one embodiment, each of the first and second sections includes a shoulder which extends along the top, bottom and peripheral edges thereof. Each of the shoulders includes inner and outer surfaces and the clips on the first section are formed in and extend outwardly from the shoulder thereon. The cut-outs in the second section are formed in and extend parallel to the shoulder thereon.
Moreover, in this embodiment, the clips extend generally perpendicularly outwardly between the inner and outer surfaces of the shoulder thereon and define a plurality of recesses in the shoulder. The cut-outs in the second section define a plurality of latch bars which extend in spaced-apart relationship along the shoulder thereon.
The clips further include a latch or finger whereby, when the first and second sections are coupled together, the clips extend through the respective openings formed by the cut-outs and the finger on the clips wraps around the respective latch bars formed in the shoulder on the second section.
Various other objects, aims, purposes, features, advantages, embodiments, variations, and the like will be apparent to those skilled in the art from the teachings of the present specification taken with the associated drawings and the appended claims.
