Needle for stereographic embroidery
Abstract
A needle for stereographic embroidery is mainly composed of a
main body which is provided with a tapered drilling part, shaped as
a cone for drilling through a cloth easily, and a fixing pivot, at
its other side, having a thread for screwing together with a
embroidering machine. The tapered drilling part, being shaped as a
cone, can drill through a hole of the cloth to squeeze outwards the
longitudinal and the latitudinal yarns around the hole without
damaging to them, achieving the previous drilling action in the
stereographic embroidery and keeping the cloth as a whole. Because
the drilling action does not damage to any yarns but squeezes them
outwards, it provides a more complete basis for embroidering on the
yarns to obtain a more vivid and stereographic picture.

triangle pyramid.
5. The needle for stereographic embroidery as claimed in claim 1,
wherein said tapered drilling part can be formed as a smooth
quadrilateral pyramid.
6. The needle for stereographic embroidery as claimed in claim 1,
wherein said tapered drilling part can be formed as a smooth
pyramid.
7. The needle for stereographic embroidery as claimed in claim 1,

Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] This invention relates to a needle for stereographic
embroidery, particularly to one that carries out the previous
drilling work without breaking down yarns of a cloth to keep the
cloth as a whole, enabling the needle to avoid the defects,
breaking down the yarns and reducing the strength of the cloth, the
conventional has. Since the drilling action in the present
invention does not damage the cloth as the conventional does, it
provides a more complete basis for embroidering on the yarns with a
more vivid and stereographic picture. And, due to a drilling
circumference of a tapered drilling part is shaped as a cone, it is
to endure an even force, reducing abrasion greatly.
[0003] 2. Description of the Prior Art
[0004] A conventional needle for embroidering, as shown in FIGS. 1
and 2, is mainly composed of a main body 1 provided with a tapered
drilling part 2 and a fixing pivot 3. The tapered drilling part 2
is formed as a quadrilateral pyramid provided with four ar tes 22
and a drilling tip 21. Because the ar tes 22 is rather sharp, they
may cut off the longitudinal and the latitudinal yarns of the cloth
while drilling through the cloth for embroidering, causing damage
to the structure of the cloth losing its original strength. And,
the ar tes 22 after numerous drillings are to diminish their
sharpness, so that they must be replaced often.
[0005] In addition, a combined method of making stereographic
texture and embroidering, patent No. 90118513 authorized by
Taiwanese Patent Office, uses a reverse U-shaped "reversed-fork
needle" to hook the yarn outwards. The U-shaped "reversed-fork
needle" is form of very tenuous so that it is to deform easily
after long-term use. Therefore, if lots of the U-shaped
"reversed-fork needles" are used in a huge embroidering machine, it
would take a lot of time to replace and correct them, causing a low
efficiency and a higher cost.
[0006] Therefore, this invention has been studied to improve the
structural defects in the conventional.
SUMMARY OF THE INVENTION
[0007] The prime object of this invention is to offer a needle that
does not break down the longitudinal and the latitudinal yarns in a
cloth, keeping the cloth as a whole.
[0008] The main characteristics of the invention are:
[0009] 1. A drilling tip in the present invention is form as a flat
circle that is to pass through a hole of the cloth first. Then, a
drilling circumference is to squeeze outwards the yarns around
it.
[0010] 2. The drilling circumference can squeeze outwards the yarns
around it to provide a good basis for embroidering, able to obtain
a more stereographic and aesthetic picture on the cloth.
[0011] 3. The drilling circumference has a smooth coned surface so
that it is to endure an even force while drilling, minimizing the
abrasion.
[0012] 4. The drilling circumference can be varied into other
shapes as long as it maintains smoothly as a cone and does not
break down the yarns of the cloth.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0022] As shown in FIGS. 3 and 4, a preferred embodiment of a
needle for stereographic embroidery in the present invention is
mainly composed of a main body 1 which is provided with a tapered
drilling part 2 and a fixing pivot 3. The fixing pivot 3 is
provided with a thread 31 to screw with an embroidering machine.
The tapered drilling part 2 is shaped as a smooth cone having a
drilling tip 21 and a drilling circumference 22.
[0023] In using, when the needle in the invention is to drill
through a cloth 4, the drilling tip 21 will first pass through a
hole 41 in the cloth 4 and, then, the 22 is to squeeze yarns 42 as
shown in FIG. 5, making the yarns 42 become denser. Next, while the
needle in the invention moves away from the cloth 4, the hole 41 is
kept as shown in FIG. 6. By the same time, a wanted picture can be
embroidered on the denser yarns 42, which will make the embroidered
picture be more vivid and stereographic.
[0024] Furthermore, the tapered drilling part 2 is not merely
shaped as a cone, it can be designed with a variety as long as the
longitudinal and the latitudinal yarns are not broken down. By
experiments, the tapered drilling part 2 can be instead shaped as
an ellipse, a smooth triangle pyramid, a smooth quadrilateral
pyramid or a smooth hexagonal pyramid etc. The drilling
circumference 22 is also able to be designed as a shape of a wave
or a ladder, as shown in FIG. 8, as long as it can keep the tapered
drilling part 2 being forced even to reduce abrasion and not
harmful to the longitudinal and the latitudinal yarns.
[0025] While the preferred embodiment of the invention has been
described above, it will be recognized and understood that various
modifications may be made therein and the appended claims are
intended to cover all such modifications that may fall within the
spirit and scope of the invention.
