Description
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.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0027] Referring to FIGS. 5 to 9, the nail 3 of the present
invention comprises a head 30, a cylindrical shank 31 connected to
the head 30, a plurality of threads 34 defined in an outer
periphery of the shank 31, a cone-shaped tip portion 33 connected
to an end of the shank 31, and a plurality of wings 32 extending
from the tip portion 33. The threads 34 are located between the
head 30 and the wings 32, and each of the wings 32 has a cutting
edge 321. The tip portion 33 is an elongate flat portion and the
wings 32 are located at a distance from a tip 330 of the tip
portion 33. The wings 32 extend outward from a tip 330 of the tip
portion 33 and an outer diameter of two diagonally located wings 32
is smaller than an outer diameter of the shank 31.
[0028] As shown in FIGS. 6 to 12, when penetrating the nail through
a board 4, the tip 330 of the tip portion 33 first cuts into the
board 4 to form a slot 40 as shown in FIGS. 6 and 10, and then the
wings 32 cut into the board 4 as shown in FIGS. 7 and 11. The wings
32 cut the inner periphery of the hole 41 in the board into four
slits 410 and four parts 411 which extend downward. Further
referring to FIGS. 8 and 12, the nail 3 is then moved linearly into
the board 4 to let the cone-shaped tip portion 33 penetrate through
the board 4, the slits 410 are further extended by the larger
diameter of the tip portion 33 and the shank 31 so as to form two
short recesses 411' in two sides of each part 411. The nail 3 is
continuously penetrated through the board 4 linearly and the parts
411 and the insides of the recesses 411' are engaged with the
threads 34 to firmly grasp the nail 3. It is noted that the parts
411 do not curve outward so that the shank 31 of the nail 3 is
snugly engaged with the hole 41. This nail 3 ensures that the nail
3 is not easily to be pulled from the board 4.
[0029] FIG. 13 shows another embodiment of the nail 3 wherein the
only difference from that of FIG. 5 is that the outer diameter of
two diagonally located wings 32 is larger than an outer diameter of
the shank 31. Referring to FIGS. 14 to 21, when penetrating the
nail 3 into the board 4, the wider wings 32 cut the inner periphery
of the hole 41 to have four long slits 410 between four parts 411,
and the four parts 411 are engaged with the threads 34 of the nail
3.
[0030] FIGS. 22 to 24 show yet another embodiment of the nail 3
wherein the tip portion 33 is a cylindrical section with a
cone-shaped tip and the wings 32 extend outward from the
cylindrical section and an outer diameter of two diagonally located
wings 32 is larger than an outer diameter of the shank 31. FIG. 25
shows a further embodiment of the nail 3 wherein the wings 32
extend from the tip of the tip portion 33 and an outer diameter of
two diagonally located wings 32 is larger than an outer diameter of
the shank 31.
[0031] All the wings 32 of the previous embodiments each include a
cutting edge 321 that a downward slope which slopes toward the head
30 of the nail 3.
[0032] FIGS. 26 and 27 show two embodiments wherein the wings 32
cutting edges 321 of wings 32 each have an upward slope which
slopes away from the head 30.
[0033] FIG. 28 shows that the wings 32 extend continuously from the
tip portion 32 and the shank 31 and are connected to an underside
of the head 30.
[0034] While we have shown and described the embodiment in
accordance with the present invention, it should be clear to those
skilled in the art that further embodiments may be made without
departing from the scope of the present invention.
