STRUCTURE OF SUPPORTER FOR TIE KNOT OF KNOTTING-
FREE NECKTIE
Field of the Invention
The present invention relates to a knotting-free necktie, and
more particularly, to a structure of a supporter for the tie knot of a
knotting-free necktie.
Description of the Prior Art
Up to now, business suit has become a common dress in the
world. However, it is unknown who designs the business suit. Since
the collar of the shirt is open, the original business suits are most likely
to be worn in a tropical area rather than a frigid zone, and thus when
people living in the frigid zone wear the business suit, they will use a
scarf around the neck and knot the scarf for protecting them from cold.
At first, the purpose of the scarf is to protect people from cold, but later
the scarf is found to be ornamental and a necktie is gradually developed.
This maybe can explain how the necktie is developed, but the real reason
is unknown. Today, the necktie has totally become a part, even a main
part of the business suit. If a man wears a business suit without a
necktie, he can not be accepted in a formal occasion and will be deemed
to be impolite or not be dressed neatly.
An ordinary necktie is generally made by sewing a fabric into an
elongate strip having a wider head portion and a narrower tail portion.
When in use, the waist portion of the strip is wound under the collar of
the shirt and is formed into a tie knot, and then the head portion of the
strip will suspended from the collar, in front of the user's chest. When
people want to knot such a necktie, it is difficult to determine the
CA 02249774 1998-10-07
optimum position of the knotting, and thus it is not efficient. Hence,
people have proposed knotting-free neckties to solve this problem.
Some knotting-free neckties are hung on the collar by means of
a hook, and some improved knotting-free neckties utilizes zippers to
control the upward-and-downward movement of the tie knot. However,
the zipper has a tooth portion, which will make people feel
uncomfortable when touching them. It is also necessary to use locking
means to prevent the zipper from sliding after being pulled; however, it is
not appropriate to mount a tab or a slide on the necktie for controlling
and locking the zipper, and thus the zipper can not be locked and is liable
to slide such that the tie knot cannot be stable and held at the collar and
will gradually slide downward.
For solving this problem, the best way is to study the supporter
for the necktie, and the purpose of the present application is to provide a
supporter for the necktie.
Summaror of the Invention
To form a tie knot by winding a fabric strip (i.e., a necktie)
around the supporter according to the present application, an outer shell
of the supporter is formed into a reverse triangular shape and has two
waist portions concave inward of the outer shell, as seen from its front
view. The outer shell is of a bow shape if seen from its top view. The
rear side of the outer shell is provided with a protective beam, resistant
shoulders and protective tabs in order to guide the sliding of a loop cord.
A back wing is fitted onto the rear side of the outer shell, and has two
side wing portions, which are somewhat resilient and are lightly pressed
against the resistant shoulders such that the loop cord passing over the
resistant shoulders can move smoothly but not slidably and make the tie

knot, which can be moved upward-and-downward by means of the
movement of the loop cord, produce an appropriate resistant force
against sliding.

Retailed Description of the Invention
Figs. 1 A, 1 B and 1 C show a front view, a side view and a top
view of the outer shell of the supporter according to the present invention,
respectively. Figs. 2A is a rear view of the outer shell and Fig. 2B is a
sectional view of the outer shell of Fig. 2A along a line A-A.
As seen from these figures, the outer shell ( 1 ) of the supporter
according to the present invention is substantially in a shape of reverse
triangle, and two waist portions ( 11 a, 11 b) of the outer shell ( 1 ) are
concave inward of the outer shell (1). As seen from the top view of the
outer shell ( 1 ), it is in a shape of bow. The outer shell ( 1 ) according to
the present invention is so designed that an ornamental tie knot can be
formed by merely winding a fabric strip onto the outer shell ( 1 ) and
knotting the fabric strip, while a conventional necktie has to be wound
several times in order to form a mufti-layer tie knot for matching the
4
CA 02249774 1998-10-07
collar.
To support an ornamental appearance of the tie knot is merely
one of the functions of the supporter. The main function of the
supporter is to control the upward-and-downward movement of the tie
knot and holding the tie knot in an appropriate position. The following
description will explain how to achieve this obj ect.
As seen from Fig. lA, a rectangular window (17) formed above
a fixing hole ( 13 ) and two slots ( 16a, 16b) formed respectively at two
sides of the upper edge of the outer shell ( 1 ) have no special functional
effect but are merely made from a mold, and thus will not be described in
detail here. A protective beam ( 14), protruding resistant shoulders ( 18a,
18b) and protection tabs (15a, 15b) are provided at the rear side of the
outer shell ( 1 ).
Fig. 3A is a front view of a back wing (2) of the supporter
according to the present invention; Fig. 3B is a side view of the back
wing (2); and Fig. 3C is a top view of the back wing (3).
The back wing (2) can be fitted onto the outer shell ( 1 ), as
shown in Fig. SA, and a fixing hole (23) of the back wing (2) aligns with
the fixing hole ( 13) of the outer shell ( 1 ). By threading a rivet into the
fixing hole (13, 23), the back wing (2) can be fixed onto the outer shell
( 1 ). A hanging portion (22) is adapted to be hung on a small groove ( 12)
provided in the middle of the upper edge of the outer shell ( 1 ) in order to
prevent the biasing of the back wing (2). Two side wing portions (21 a,
21b) directly press against the resistant shoulders (18a, 18b), respectively.
Because the back wing (2) is made of a resilient plastic material and its
wing trunk (24) and the two side wing portions (21 a, 21 b) are all flat,
when the fixing hole (23) of the back wing (2) is fixed onto the outer
shell ( 1 ), the pressure applied by the two side wing portions (21 a, 21 b)
s
CA 02249774 1998-10-07
on the resistant shoulders (18a, 18b) is a resilient action, and when
forming a tie knot, a fabric strip (4) will be wound around and be pressed
against the outer ends of the two side wing portions (21 a, 21 b) and thus
produce a resilient pressure onto the two side wing portions. Such
pressure can produce an appropriate resistance on a moving loop cord (3),
which is between the resistant shoulders ( 18a, 18b) and the two side
wing portions (21a, 21b) (see Fig. 6), such that the loop cord (3) can be
pulled smoothly but not slidably, and if no foreign force is applied to the
loop cord (3), the loop cord (3) will be held in a position and will not
move. Because the tie knot is formed by winding the fabric strip around
the supporter, the smooth and stable movement of the supporter when
being pulled results in the smooth and stable upward-and- downward
movement of the tie knot. Although the resistance can firmly hold the
tie knot on the collar, it will not produce pressure on the throat of the
user. The natural tension of the neck muscle can automatically adjust
the tightness of the loop cord.
Fig. 4A is a front view of an assembled supporter according to
the present invention, in which the back wing is connected with the outer
shell; Fig. 4B is a side view of the assembled supporter of Fig. 4A; and
Fig. 4C is a top view of the assembled supporter of Fig. 4A.
Fig. SA is a rear view of the supporter of Fig. 4A showing the
back wing (2) of Fig. 3A fitted onto the back of the outer shell (1) of Fig.
2A; and Fig. SB is a sectional view of the supporter of Fig. SA along a
line B-B.
As seen from these figures, the resistant shoulders (18a, 18b)
shown in Fig. 2A is covered by the two side wing portions (21 a, 21 b) of
the back wing (2).
In Fig. 6, the loop cord (3), which is formed into two strands, is
6
CA 02249774 1998-10-07
threaded in the supporter from the bottom of the protective beam ( 14),
and then passes under the two side wing portions (21 a, 21 b) of the back
wing (2) and is threaded out of the supporter from the bottom of the
protective tabs (15a, 15b).
Fig. 7 shows a loop cord (3), which is a part of the necktie and
can be fitted around the collar. The loop cord is made of a fabric having
appropriate softness, and it can be a loop cord having a round section, or
be a flat loop cord, but the former is preferable.
Fig. 8 shows the appearance of the loop cord (3) of Fig. 7 that
passes through the supporter in a manner shown in Fig. 6, and the portion
of the loop cord (3) above the supporter forms an adjustable collar ring
(31).
Fig. 9 shows a fabric strip (4). As seen from the figure, the
fabric strip (4) has a fixing hole (41 ) at its bottom end. When mounting
the fabric strip (4), the user can use a rivet passing through the fixing
hole (41 ) of the fabric strip (4), the fixing hole ( 13 ) of the outer shell
( 1 )
and the fixing hole (23) of the back wing (2) in order to connect the
fabric strip (4), the outer shell ( 1 ) and the back wing (2) together, and
then wind the fabric strip (4) around the supporter in order to form a tie
knot (42) and fix the same whereby a knotting-free necktie is obtained.
Fig. 10 is an appearance of the whole knotting-free necktie.
When in use, the user first puts the collar ring (31 ) under the collar of the
shirt and arrange the collar, and then use one hand to hold the tie knot
(42) and another hand to pull the loop cord (3) from the back of the
fabric strip in order to smoothly move the tie knot (42) toward the collar.
At this time, the collar ring (31 ) is completely covered by the collar and
thus invisible as seen from the outside of the collar, and only the tie knot
is exposed at the collar. Hence, the knotting-free necktie is the same as
7
CA 02249774 1998-10-07
the conventional necktie in visual effect. When releasing the necktie,
the user only need to pull the tie knot downward and take the collar ring
away from the neck of the user. Hence, the knotting-free necktie in
accordance with the present invention is very convenient for users.
The present invention is not limited by the forgoing description
of the embodiments, the invention may be embodied in other specific
forms without departing from the spirit or essential characteristic of the
appended claims.
