DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0020] With reference to FIGS. 1 to 10, a fabric folding machine
100 according to a preferred embodiment of the present invention
comprises: a body 10 and a limiter 20.
[0021] Referring to FIGS. 1 to 6, the body 10 is integrally formed
and includes an external housing 11, an internal housing 12, and a
connection portion 13. The external housing 11 has a first
peripheral fence 111, a second peripheral fence 112 opposite to the
first peripheral fence 111, and two third peripheral fences 113
connected with the first peripheral fence 111 and the second
peripheral fence 112, wherein the internal housing 12 is disposed
in the external housing 11 and is spaced from the external housing
11 by a gap defined by a through hole 14, i.e., the through hole 14
is located between the external housing 11 and the internal housing
12. The through hole 14 has a first segment 141 and a second
segment 142, and a height of the first segment 141 is more than
that of the second segment 142. The connection portion 13 is in
connection with the first peripheral fence 111 of the external
housing 11 and the internal housing 12 and its width gradually
decreases from the first segment 141 to the second segment 142,
wherein the first peripheral fence 111 has a first orifice 115
defined thereon, the second peripheral fence 112 has a second
orifice 116 communicating with the through hole 14, and the second
peripheral fence 112 also has two guiding apertures 117
communicating with the through hole 14. The third peripheral fence
113 has an anti-slip portion 118 arranged on an outer surface
thereof, and the anti-slip portion 118 is a rough face.
[0022] As shown in FIGS. 1 to 3, the limiter 20 includes a sheet 21
and a protrusion 22 extending outwardly from the sheet 21 so as to
alternatively accommodate in the first orifice 115 or the second
orifice 116 of the body 10, wherein the sheet 21 has two openings
211 defined thereon.
[0023] In operation, a fabric strip 90 is folded in half and is
inserted toward the second segment 142 of the through hole 14 from
the first segment 141 of the through hole 14, as illustrated in
FIGS. 7 and 8, hence after the fabric strip 90 extends out of the
second segment 142, its two peripheral sides are folded inwardly,
as shown in FIG. 7.
[0024] Thereafter, the protrusion 22 of the limiter 20 is inserted
into the second orifice 116 of the body 10, and the fabric strip 90
is inserted toward the second segment 142 of the through hole 14
from the first segment 141 of the through hole 14 again, as shown
in FIGS. 9 and 10, and the protrusion 22 stops the fabric strip 90
between the second peripheral fence 115 and the through hole 14,
such that after the fabric strip 90 extends out of the second
segment 142, its two peripheral sides are folded in half again by
using the through hole 14, as illustrated in FIG. 9, thus folding
the fabric strip 90 repeatedly.
[0025] When the protrusion 22 of the limiter 20 is arranged in the
second orifice 116 of the body 10, the two openings 211 of the
limiter 20 are in communication with the two guiding apertures 117
of the body 10, as shown in FIG. 9. After inserting an elongated
object (not shown) through the two openings 211 and the two guiding
apertures 117 and aligning the elongated object with the through
orifice 14, the fabric strip 90 is moved smoothly in the fabric
folding machine 100 by the elongated object.
[0026] Furthermore, the limiter 20 is operated by user's left hand
or right hand alternatively. Preferably, the sheet 21 has two arrow
symbols 212 marked thereon so as to indicate operating
direction.
[0027] With reference to FIGS. 1 to 3, when the sheet 21 is located
on a first face of the protrusion 22, it has a first indication
symbol 1'' denoted by a reference number 213 so as to fold the
fabric strip 90 in one inch, and when the sheet 21 is located on a
second face of the protrusion 22 opposite to the first face of the
protrusion 22, it has a second indication symbol 2'' represented by
a reference number 214 so as to fold the fabric strip 90 in two
inches.
[0028] While the preferred embodiments of the invention have been
set forth for the purpose of disclosure, modifications of the
disclosed embodiments of the invention as well as other embodiments
thereof may occur to those skilled in the art. Accordingly, the
appended claims are intended to cover all embodiments which do not
depart from the spirit and scope of the invention.
