DESCRIPTION OF THE CURRENT EMBODIMENT

(7) An embodiment of the folding knife with pocket clip of the present invention is shown and generally designated by the reference numeral 10.

(8) FIG. 1 illustrates the improved folding knife with pocket clip 10 of the present invention, and FIGS. 2-5 illustrate the pocket clip removed from the folding knife. More particularly, the folding knife with pocket clip has a knife frame 12. The knife frame has a pivot end 14 to which a blade 16 is pivotally attached. In FIG. 1, the blade is shown in the unfolded position. A flexible elongated resilient pocket clip 18 having a first end 20 is connected to the knife frame. The flexible elongated resilient pocket clip also has a second free end 22 proximate the knife frame. The flexible elongated resilient pocket clip defines a plurality of louvers/deflected portions 24. Each louver defines a slit 26 transverse to the length of the flexible elongated resilient pocket clip and has an elevated edge 28 at the slit.

(9) In the current embodiment, each elevated edge 28 faces toward the second free end 22 of the flexible elongated resilient pocket clip 18. The louvers 24 are parallel to each other. The louvers are at an intermediate location spaced apart from the first end 20 and second free end. The elevated edges face toward the pivot end 14 of the knife frame 12. The flexible elongated resilient pocket clip has a selected thickness, and each louver is deflected by an amount greater than the thickness. Each louver defines an aperture 30 extending through the flexible elongated resilient pocket clip. The flexible elongated resilient pocket clip has a planar major surface 32, and each louver has an area 34 deflected from the planar major surface, the louver being continuous with the planar major surface on all sides except the slit 26. In the context of the specification, “continuous” means without a discontinuity at any bend point 36. The sheet metal of the flexible elongated resilient pocket clip is bent at these edges, but remains unsheared. Each louver has an arc-shaped periphery 38 connected to the flexible elongated resilient pocket clip. Each slit is a straight line. The flexible elongated resilient pocket clip is a planar body having opposed elongated side edges 40, 42. The louvers are spaced apart from the opposed elongated side edges.

(10) The flexible elongated resilient pocket clip 18 is releasably attached to the knife frame 12 by screws 44 (only one of which is visible) received in a pair of threaded apertures (not visible) at a free end 46 of the knife frame. The knife frame also has a pair of threaded apertures 48 at the pivot end 14 so the user can change the attachment position of the flexible elongated resilient pocket clip to the pivot end of the knife frame if desired.

(11) The flexible elongated resilient pocket clip 18 clips over the outside of a pocket or pouch when the folding knife with pocket clip 10 is in the folded position and stowed condition. The plurality of louvers 24 provide enhanced grip for a more reliable grasp by the user when retrieving the folding knife with pocket clip from a pocket or pouch. The elevated edges 28 face toward the second free end 22 of the flexible elongated resilient pocket clip so the elevated edges are in a direction opposite the force of extraction of the folding knife with pocket clip from a pocket or pouch. The elevated edges provide a grip advantage only in one direction. The slope 50 of the unsheared side of each louver provides space 52 for the user's gripping finger to enter the space to engage the adjacent louver's elevated edge more readily. However, the plurality of louvers could be sheared on both sides, thereby providing straps that are connected to the flexible elongated resilient pocket clip only at their ends, which would create an enhanced gripping effect in both directions, and also provide different manufacturability and use advantages.

(12) The plurality of louvers 24 are particularly advantageous in that the stamping and forming process that creates the flexible elongated resilient pocket clip 18 can form the flexible elongated resilient pocket clip's contour, hold, and periphery in a single sequence of steps, or even in a single operation. This contrasts with conventional friction features that are typically applied in a separate manufacturing step.

(13) While a current embodiment of a folding knife with pocket clip has been described in detail, it should be apparent that modifications and variations thereto are possible, all of which fall within the true spirit and scope of the invention. Although folding knives have been disclosed, the flexible elongated resilient pocket clip is also suitable for use with any other type of pocket tool or object carried in a pocket or bag where clipping the pocket tool or object to the exterior of the pocket or bag is desirable. With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

(14) Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
