Description
TECHNICAL FIELD
[0001] The present invention relates to a complex-patterned wire
net, which is mainly used for fences, and a method for
manufacturing the same, and more particularly to a
complex-patterned wire net, in which various-shaped holes are mixed
to have various kinds, and a method for manufacturing the same.
BACKGROUND ART
[0002] In general, wire nets are mainly used for fences in stalls,
factories, dams, military installations, water supply protection
zones, etc., and are advantageous in that they sufficiently satisfy
basic functions as fences, reduce a construction cost, and secure a
field of vision through net holes.
[0003] Wire nets, which are being produced now, are three kinds,
i.e., a tetragonal wire net, a pentagonal wire net, and a hexagonal
wire net, which have different shapes of net holes. These wire nets
are formed by continuously repeating the same-sized holes having
any one shape, given according to kinds, in all directions. The
shapes of the holes according to kinds are the same and the kinds
of the wire nets according to the shapes of the holes are only
three, thereby highly limiting consumer's choices. Particularly,
wire nets having the same shape have been used for a long period
without transformation of the shapes of net holes, and thus cause
the deterioration of a design value, thereby being gradually
disregarded by consumers. Accordingly, measures to cope with this
problem have been urgently required in the art.

BEST MODE
[0015] Now, preferred embodiments of the present invention will be
described in detail with reference to the annexed drawings.
[0016] In the drawings, the same or similar elements are denoted by
the same reference numerals even though they are depicted in
different drawings. In the following description of the present
invention, a detailed description of known functions and
configurations incorporated herein will be omitted when it may make
the subject matter of the present invention rather unclear.
[0017] FIGS. 1 and 2 illustrate a complex-patterned wire net in
accordance with one embodiment of the present invention. A
complex-patterned wire net (A) in accordance with this embodiment
is obtained by repeatedly forming a plurality of first net holes
100, forming a plurality of second net holes 200 under the first
net holes 100, and then forming a plurality of first net holes 100
under the second net holes 200. The first net holes 100 are formed
by twisting parts 110, 120, and 130, extensions 140, 150, and 160
formed by stretching longitudinal wires from the twisting parts
110, 120, and 130 to the right and left, and divisional transversal
wires 170 and 180 crossing the twisting parts 110, 120, and 130,
and the second net holes 200 are formed by twisting parts 210
twisted from the lowermost extensions 160 and several compartmental
transversal wires 220 crossing the twisting parts 210.
[0018] Here, the twisting parts 110 located at the start point of
the first net holes 110 are obtained by twisting two strands of
longitudinal wires. Longitudinal wires are stretched from the
twisting parts 110 to the right and left and are twisted with the
neighboring longitudinal wires twice, the divisional transversal
wire 170 is supplied among the longitudinal wires and then the
longitudinal wires are twisted twice again, thus producing the
twisting parts 120. Thereafter, longitudinal wires are stretched
from the twisting parts 120 to the right and left and are twisted
with the neighboring longitudinal wires twice, and the divisional
transversal wire 180 is supplied among the longitudinal wires and
then the longitudinal wires are twisted twice again, thus producing
twisting parts 130. Thereby, the first net holes 100 each having a
small regular square shape, which make a pair such that the
divisional transversal wires 170 and 180 are interposed between the
pairs of the first net holes 100, longitudinally alternate with one
another.
[0019] When the twisting parts 110, 120, and 130 for forming the
first net holes 100 are formed, the longitudinal wires of the
twisting parts 110, 120, and 130 are twisted in the opposite
directions among each other, and the longitudinal wires of the
upper and lower portions of each of the twisting parts 110, 120,
and 130 are twisted in the opposite directions with respect to the
divisional transversal wires 170 and 180. Further, only in the case
that the first net holes 100 are formed in an even number, it is
possible to perform a continuous operation. When a wire net is
manufactured using a wire net manufacturing apparatus, respective
longitudinal wires are supplied from a feed unit, and pass through
semicircular gears in a pair, which are rotated together at their
positions or are rotated together with the rotation of a
neighboring semicircular gear by a sliding operation, thus forming
the twisting parts 110, 120, and 130, which longitudinally
alternate with one another under the condition that the extensions
140, 150, and 160 are interposed between the twisting parts 110,
120, and 130. In this process, the semicircular gears cannot
perform the sliding operation more than one column space from the
viewpoint of its own structural characteristics. Further, since the
semicircular gears provide the same twisting frequency of the
longitudinal wires also to the feed unit at the rear of the
semicircular gears when the longitudinal wires of the twisting
parts 110, 120, and 130 are twisted by rotation, after the
semicircular gears are rotated in any direction, the semicircular
gears must be rotated in the other direction so as to perform
twisting at the same frequency as that of the twisting parts 110,
120, and 130 such that transversal wires twisted at the feed unit
cannot be twisted any more but can be untwisted at once so as to
perform the continuous operation.
[0020] The first net holes 100 are completed by stretching
longitudinal wires from the lowermost twisting parts 130 to the
right and left and twisting the longitudinal wires with the
neighboring longitudinal wires. Thereafter, the longitudinal wires
are twisted four times, one divisional transversal wire 220 is
supplied among the longitudinal wires, the longitudinal wires are
twisted again four times, and then another divisional transversal
wire 220 is supplied among the longitudinal wires. This procedure
is repeated, thus producing the twisting parts 210. Thereby, the
second rectangular net holes 200, each having a rectangular shape,
which are divided by the compartmental transversal wires 220, are
formed.
[0021] When the second net holes 200 are formed, the twisting parts
210 at a twisting start point are twisted in the opposite direction
to the twisting direction of the lowermost twisting parts 130 of
the first net holes 100, and the portions of the twisting parts 210
divided by the compartmental transversal wires 220 are twisted in
the opposite directions with respect to the compartmental
transversal wires 220. Further, only in the case that the second
net holes 200 are formed in an even number, it is possible to
perform a continuous operation without excessively twisting the
longitudinal wires in any one direction.
[0022] Therefore, the first net holes 100 obtained by the present
invention cannot vary in lateral width due to the intervals between
the neighboring twisting parts 110, 120, and 130, but the first net
holes 100, each having a small regular square shape are formed in
zigzag by twice-twisting each of the upper and lower portions of
the longitudinal wires of the twisting parts 110, 120, and 130
divided by the divisional transversal wires 170 and 180 between the
extensions 140, 150, and 160. Further, the second net holes 200,
each having a rectangular shape, which is vertically elongated, are
formed under the first net holes 100 by four times-twisting each of
the portions of the longitudinal wires of the twisting parts 210
divided by the compartmental transversal wires 220. Further, when
the first net holes 100 and the second net holes 200 are
respectively formed in even numbers, it is possible to perform the
continuous operation regardless of the numbers of the first and
second net holes 100 and 200. Thus, complex-patterned wire nets (A)
of various kinds are obtained by varying the numbers of the first
and second net holes 100 and 200, i.e., two first net holes 100 and
two second net holes 200, two first net holes 100 and four second
net holes 200, or four first net holes 100 and two second net holes
200.
[0023] FIGS. 4 and 5 illustrate a complex-patterned wire net in
accordance with another embodiment of the present invention. In
this embodiment, as shown in FIGS. 3 and 4, a complex-patterned
wire net (B) having a new type is obtained by varying the twisting
frequency of twisting parts 310, 320, and 330 to obtain first net
holes 300 and the twisting frequency of twisting parts 410 to
obtain second net holes 400.
[0024] That is, longitudinal wires of the twisting parts 310, 320,
330, and 410 of the first and second net holes 300 and 400 are
twisted in the opposite directions and the first and second net
holes 300 and 400 are respectively formed in even numbers so as to
perform a continuous twisting operation. The longitudinal wires of
upper and lower portions of the twisting parts 310, 320, and 330
divided with divisional transversal wires 370 and 380 are
respectively twisted four times so as to form the first net holes
300, each having a rectangular shape, which is vertically
elongated, and the longitudinal wires of portions of the twisting
parts 410 divided with compartmental transversal wires 420 are
respectively twisted twice so as to form the second net holes 400,
each having a regular square shape.
[0025] Also, complex-patterned wire nets (B) of various kinds are
obtained by varying the numbers of the first and second net holes
300 and 400, i.e., two first net holes 300 and two second net holes
400, two first net holes 300 and four second net holes 400, or four
first net holes 300 and two second net holes 400.
[0026] FIG. 6 is a perspective view of a complex-patterned wire net
in accordance with another embodiment of the present invention. In
this embodiment, divisional transversal wires 570 and 580 of first
net holes 500 and compartmental transversal wires 620 of second net
holes 600 have a wave shape, in which protrusions and depressions
are repeated.
[0027] That is, the transversal wires 570, 580, and 620 are
supplied among longitudinal wires during twisting the longitudinal
wires for forming twisting parts 510, 520, 530, and 610, and thus
divide the respective net holes 500 and 600 from each other. In the
case that the transversal wires 570, 580, and 620 have a wave
shape, the transversal wires 570, 580, and 620 are more firmly
bonded to the twisting parts 510, 520, 530, and 610, and thus
enhance the strength of a wire net (C) and create a new aesthetic
value of the wire net (C) while having the same sizes of the net
holes 500 and 600.
[0028] FIG. 7 is a perspective view of a complex-patterned wire net
in accordance with yet another embodiment of the present invention.
In this embodiment, a twisted wire obtained by twisting two strands
of wires is used as divisional transversal wires 770 and 780 of
first net holes 700 and compartmental transversal wires 820 of
second net holes 800.
[0029] The transversal wires 770, 780, and 820 using the twisted
wire are more firmly bonded to twisting parts 710, 720, 730, and
810, and thus enhance the strength of a wire net (D) and create a
new aesthetic value of the wire net (C) while having the same sizes
of the net holes 700 and 800.
[0030] FIG. 3 is a schematic view of a complex-patterned wire net
of the present invention, when the wire net is used as a fence. The
complex-patterned wire net (A) of the present invention includes
first and second net holes 100 and 200 having different sizes and
shapes, and thus has a new aesthetic value and safety in
appearance, thereby increasing in utility value.
INDUSTRIAL APPLICABILITY
[0031] As apparent from the above description, the present
invention provides a complex-patterned wire net (A), in which net
holes 100 and 200 having different sizes and shapes are arranged,
and a method for manufacturing the same. Particularly, the first
net holes 100 in an even number are formed in zigzag by twisting
parts 110, 120, and 130, divisional transversal wires 170 and 180
crossing the twisting parts 110, 120, and 130, and extensions 140,
150, and 160, and the second net holes 200 in an even number are
formed by twisting parts 210 twisted from the lowermost extensions
160 and several compartmental transversal wires 220 crossing the
twisting parts 210 at proper intervals. Further, it is possible to
obtain wire nets of various kinds having different overall shapes
by varying the twisting frequencies of the twisting parts 110, 120,
130, and 210 and the numbers of the net holes 100 and 200, thus
providing complex-patterned wire nets having new and various shapes
and increasing the utility value of the wire nets.
