A PREKNOTTED ADJ~STABLE NECKTIE
. _ _
Neckties are a major part of attire for men all
over the world. When wearing a necktie, it is
necessary to tie a knot. For men having ample time, it
is enjoyable to wear a necktie and have the knot tied
carefully. But for men who are busy, it is a great
burden to wear a necktie so far as the time for tying
the knot is concerned. However, according to customs,
courtesies, and special rules (such as those for
members of the armed forces), wearing a necktie is
necessary. The preknotted necktie of the present
invention is so designed as to address these
conditions.
Conventional preknotted neckties are of many
types. Among others, there are neckties which use a
zipper as control means. These neckties are either
inconvenient to use or uncomfortable to wear, and
besides, it is diEficult to have the tie knot properly
fixed yet such that the tie knot is easily slid out of
position. The zipper starts sliding very easily if a
stopper i9 not provided therein; but if a stopper is
used with the zipper, the pull button that controls the
sliding of the zipper has to be in different positions
when the button is used for pulling and when it is at
rest. The button, when used for pulling, must be
1 7 ~ r 1 7
-- 2 --
pulled away ~rom the zip fastener. For a necktie,
however, the button must be hidden in the back or it
will spoil the appearance of the necktie. But if the
pull button is hidden in the back, it will press
against the portion externally of the wearer's throat,
~hich makes the wearer feel very uncomforatable.
The necktie of the present invelltion is intended
to address the above-mentioned disadvantages. The
present invention provides a preknotted adjustable
necktie comprising an inner tie member which comprises
a loop portion to surround a users neck in use and a
portion depending from said loop portion, the junction
between said loop portion and said depending portion
incorpor~ating a æip fastener having an adjustment
slider whereby the size of the loop portion may be
adjusted, a knot former comprising an inner body and an
outer body connected together, with the inner tie
member passing between the inner body and the ou~er
body and the slider of the zip fastener fixed to the
knot former, and an outer tie member fastened to said
knot former, arranged as a knot over the knot former
and depending therefrom, such that the positio~ of the
knot former on the inner tie member may be varied to
tighten and to loosen the loop portion.
In a preferred embodiment of the present
invention, the knot former on which the outer tie
1 30851 7

member may be tied into a knot is divided into an inner
body and an outer body which connect together. The two
bodies are fitted one over the other with a controL
slot provided therebetween for the inner tie member
sliding therein, a pair of leaf springs being provided
on depending portions of the inner body. In addition
to increase resistance to sliding movement, said leaf
springs serve to produce a resistance to downward
sliding movement which is much greater than that to
upward pulling movement so as to obtain a necktie which
is characterised in that the tie knot is easy to pull
up but difficult to slide down.
The structure of a preferred necktie according to
the present invention will now be described by way of
illustration with reference to the accompanying
drawings in which:
Figure 1 shows the appearance of a complete
necktie according to the present invention;
Figure 2 shows the structure of the inner tie
member of the necktie.
Figure 3 shows the inner tie member of Figure 2
when fitted into the knot former;

A-A of Figure 3;

view, top view, and the cross-section view taken along
line B-B thereof, respectively;

cross-section view taken along line D-D thereof,
respectively.
Figure 1 shows the appearance of a necktie
according to the present invention, including an outer
tie member S made of fabric material used
conventionally for making neckties. The size of the
tie loop portion 2 of an inner tie member, can be
adjusted to match an individual wearer's neck~size.
Figure 2 shows the structure of the inner tie
member 1 which is a strip made of the same fabric as
the outer tie member 5, the upper portion thereof
encircling to become a closed loop 2 which is provided
1308517
-- 5 --
with a zipper 3 on the lower portion of its inner edge.
The opening and closing of the zipper is controlled by
a slider 4, said slider being provided with a pull
button 41 for pulling the slider as in the case of
conventional sliders. The only di~ference is that no
slide pin is provided on the inner side of the pull
button so the slider can be slid freely even when the
pull button is folded down on to the teeth of the
zipper.
F~gure 3 shows the inner tie member 1 of Figure 2
when fitted into the knot former 6, the inner tie
member being clamped in a control slot 7 between the
inner and outer bodies of the knot former (see Figures
5 and 7). A rivet hole 42 is provided on the pull
button 41 through which the outer tie member 5, a
depending leg 621 of the inner body 62, the outer body
61, and the pull button 41 are sequentially secured
together by a rivet 63 (see Figure 4). Then the outer
tie member S is tied into a knot over the path
indicated by phantom line 8 in the drawing thus to
produce a necktie as shown in Figure 1. Now the wearer
can adjust the size of the tie loop 2 by moving the
position of the tie knot 9 up and down by pushing the
tie knot 9 up or pulling it down with o~e hand while
holding the lower end of the inner tie member 1 (which
lies below and is shorter than the outer tie member)
with the other hand~

Figure 5 is a perspective view of the knot former
6 which forms the tie knot 9 into shape and controls
the size of the tie loop 2. Figure 6 is an exploded
view showing the knot former of Figure 5 which is
assembled by fitting the inner body 62 into the outer
body 61, an embedding slot 611 being provided in the
forward portion centrally of the outer body 61 into
which a depending leg 621 of the inner body 62 is
fitted. When the inner and outer bodies are fitted
together, a small control slot 7 is created
therebetween, said slot being of such dimension in
width as to allow the bifurcating portion of the inner
tie member at the base of the loop portion to pass
through on either side of the knot former for the
purpose of preventing the inner tie membér 2 from
becoming twisted when being pulled. Both said inner
and outer bodies are made of an elastic plastics
material.
Figure 8 shows the inner body 62 in front
elevation view, top view, and the cross-section view
taken along the line C-C thereof, respectively, in
which a leaf spring 622 is provided on both thç left
and right sides, respectively, in a depending portion
on the inner (front) side of said inner body 62.
Normally, the lower edges of said springs are biased
against the inner side of the inner tie member 1 (see
~ 7 - 1308517
Figure 4) to increase resistance to the sliding
movement of the knot former. The leaf springs 622 thus
slant inwards and downwards such that different
resistances will be imposed to the up and down
movements o the zipper slider. When the inner tie
member is pulled down and the tie knot is pushed up,
less resistance will result because the movement is in
the same direction in which the leaf springs are
slanted. On the contrary, when the tie knot 9 is moved
down, increased resistance will result because the
movement is against the direction in which the leaf
springs depending from the inner body are slanted. In
the latter case, while the resistance does not
interfere with the deliberate pulling down of the tie
knot, it is sufficient to prevent the tie knot 9 from
inadvertently sliding down.
