Brief Patent Description - Full Patent Description - Patent Application Claims
FIELD OF THE INVENTION [0001] The present invention relates to a nail that includes wings on tip so as to easily cut into object and the split portions made by the separation of the tip and wings are engaged with threads of the nail. BACKGROUND OF THE INVENTION [0002] A conventional nail 1 is shown in FIGS. 1 to 4 and generally includes a head 10, a shank 11 connected to the head 10, a plurality of threads 12 on the shank 11, and a tip 13 which is located at an end of the shank 11 and opposite to the head 10. The threads 12 are defined spirally in an outer surface of the shank 11. The threads 12 can also be replaced by axial ridges as disclosed in FIG. 3. When the nail 1 penetrates into the board 2, the tip 13 which is a conical tip, makes a hole 20 through the board 2 and the periphery of the hole 20 is torn till the shank 11 is engaged with the hole 20 and the underside of the head 10 is in contact with the surface of the board 2 as shown in FIG. 2. [0003] It is noted that the periphery of the hole 20 is torn and curves outward so that the inner diameter of the torn parts of the inner periphery of the hole 20 is larger than the outer diameter of the shank 11, so that there is gaps between the inner periphery of the hole 20 and the outer diameter of the shank 11. In other words, the nail 1 is not well secured in the board 2 and can be easily pulled out from the board 2. [0004] The present invention intends to provide a nail that is firmly engaged with the inner periphery of the hole through which the nail penetrates. SUMMARY OF THE INVENTION [0005] The present invention relates to a nail that comprises a head, a shank connected to the head, a plurality of threads defined in an outer periphery of the shank, a tip portion connected to an end of the shank, and a plurality of wings extending from the tip portion. The threads are located between the head and the wings. The nail penetrates through an object and moves linearly. The wings cut through the board and form a plurality of parts in an inner periphery of a hole through which the nail penetrates in the board. The threads are engaged with the parts. [0006] The primary object of the present invention is to provide a nail that is firmly engaged with the parts cut from the inn periphery the hole through which the nail penetrates. [0007] The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
