Abstract

PROBLEM TO BE SOLVED: To prepare an elastic net capable of reducing the distortion of the net formed on the basis of a rectangular shape and capable of being uniformly pulled in the rectangular shape. SOLUTION: The four sides of a net main body 1 formed on the basis of a rectangular shape are formed in an outward swollen shape. Edge belts elastically formed in the longitudinal direction are each subjected to pull off a string communicating and being woven in the longitudinal direction in the lateral center of the belt, and subsequently bent. The outer peripheral edges of the net main body 1 are nipped with the bent edge belts 2 and subsequently subjected to a zigzag chain stitch. Since the four sides of the net main body 1 in the elastic net thus constituted are formed in the outward swollen states, the differences in the pulling degrees between the four sides and the four corners are reduced, and the net can be uniformly pulled in the rectangular shape, when the four corners are pulled. Since the elastic edge belts 2 are attached to the outer periphery of the net main body 1, the distortion of the net main body 1 caused by pulling the four corners can further be reduced.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stretchable net having stretchability which is used for various purposes such as a bag-shaped accessory case, and a manufacturing method thereof.

[0002]

2. Description of the Related Art In general, a net is used for an accessory case, which is provided on a rear side of a backrest of a seat of a transportation means such as a vehicle or an airplane and can temporarily store small articles such as magazines.

As such a net, when used as an accessory case, a stretchable net is appropriately formed so as to correspond appropriately to the size of the accommodated accessory and hold it. Is.

Conventionally, as this type of elastic net, a net main body 11 as a frog net, in which an elastic cord 11a is hand-knitted on a frog or a knot as shown in FIG. 6, is often used. When such a stretchable net is used as an accessory case, the left and right edges and the lower edge of the net body 11 formed in a rectangular shape by a frog or a knot are sewn together with the cover at the rear of the seat when the seat is formed. By this, Fig. 7
As shown in, a net-shaped bag body having an open top is formed.

[0005]

However, in the above-described conventional elastic net, when used as a small case, it is preferable that the net main body 11 is evenly stretched on the rear surface of the seat, and the square is pulled. I am trying to attach it to the seat in the state. However, since the net body 11 is originally formed in a rectangular shape, the tensile ratio of the square is larger than that of the four pieces.
There was a problem that the four pieces were curved and the original rectangular shape was distorted.
Therefore, the appearance of the net body 11 after installation becomes poor, and it is difficult to evenly stretch the net body 11 on the rear surface of the seat.

Further, since the conventional stretchable net is a frog net having a knot in the net body 11, the knotted parts formed in a dumpling-like shape make it unattractive and impair the design.

In order to solve the above-mentioned problems, the present invention provides a stretchable net which can reduce the strain of a net formed on the basis of a rectangular shape and can be uniformly stretched in a rectangular shape, and a manufacturing method thereof. The purpose is to do.

[0008]

In order to achieve the above object, an elastic net according to the present invention comprises an elastic net formed on the basis of a rectangular shape so that each four pieces bulge outward. It is characterized in that it is provided with a provided net body 1 and an edge band 2 made of a stretchable belt-like body and attached along the outer peripheral edge of the net body 1.

Further, the method of manufacturing an elastic net according to the present invention is such that the four pieces of the net body 1 made of an elastic net formed on the basis of a rectangular shape are formed so as to bulge outward, and an elastic band is formed. The edge band 2 made of a body is bent at the center in the width direction, and is sewn so as to sandwich the outer peripheral edge of the net body 1 therebetween.

Further, in the method of manufacturing the stretchable net, the edge strip 2 is bent by pulling out a cord body which is woven in communication with the longitudinal direction at the center in the width direction.

As a result, the stretchable net is provided so that the four pieces of the net body 1 bulge outward.
The difference in tensile ratio between the four pieces and the square is reduced, and when the square is pulled, it can be stretched evenly in a rectangular shape. Further, the stretchable edge band 2 is attached to the outer peripheral edge of the net body 1. Therefore, the strain of the net body 1 that may occur when the square is pulled is reduced.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be specifically described below with reference to the drawings. FIG. 1 is a perspective view showing an elastic net of the present invention. As shown in FIG. 1, the stretchable net according to the present invention is formed on the basis of a rectangular shape, and includes a net body 1 and an edge band 2.

As shown in FIG. 2, the net body 1 is provided with a stretchable cord body 1a, a non-stretchable cord body 1b is knitted in a chain around the cord body 1a, and further adjoins at a predetermined position. The cord body 1b is connected and knitted so that the cord body 1a is connected to form a net shape. Therefore, the net body 1 is formed so as not to form a dumpling in the mesh portion.

The edge band 2 is a stretchable band body formed by weaving a stretchable cord body mainly in the longitudinal direction and the width direction, and is sewn along the outer peripheral edge of the net body 1. ing.

A method for manufacturing the above-mentioned stretchable net will be described below. First, as shown in FIG. 3, in a net body 1 formed based on a rectangular shape, four pieces are shaped so as to bulge outward.

Next, the edge band 2 is sewn to the outer peripheral edge of the net body 1. At this time, the edge band 2 is bent in the center in the width direction and is sewn so as to sandwich the outer peripheral edge of the net body 1 therebetween. Regarding the bending of the edge band 2, by pulling out the cord body that is woven in communication with the bending portion 2a at the center in the width direction in the longitudinal direction, the bending portion 2a does not swell and twist, and easily. It can be folded. Margin 2
Regarding the sewing to the net body 1, the stitches correspond to the expansion and contraction by the so-called zigzag stitch, and the edge band 2 does not easily come off from the net body 1.

When the net body 1 is formed, the outer peripheral edge of the net body 1 is cut. The cutting surface of the net body 1 is cut by melting with ultrasonic waves or heat. There is no risk that the cords 1a and 1b of 1 will be unraveled. Further, when the edge band 2 needs to be cut, the same effect can be obtained by performing the same fusing.

When the elastic net constructed in this manner is used as a small compartment for the back of the seat back, the left and right and lower edge strips 2 are sewn together with the cover at the rear of the seat when the seat is molded. A net-shaped bag body having an opening is formed. The net body 1 is formed so that its four pieces bulge outward, and the difference in tensile ratio between the four pieces and the square is reduced, so that the square is attached when the elastic net is attached to the seat side. By being sewn to the seat in the pulled state, the stretchable net is stretched in a rectangular shape on the rear surface of the seat as shown by the alternate long and short dash line in FIG.

Therefore, in the stretchable net thus constructed, the four pieces of the net body 1 are formed by bulging outward to reduce the difference in the tensile ratio between the four pieces and the square, and the square is cut. When pulled, it can be stretched evenly in a rectangular shape. Further, since the elastic band 2 is provided on the outer peripheral edge of the net body 1, the distortion of the net body 1 can be reduced.

When the edge band 2 is sewn to the outer peripheral edge of the net body 1, the edge band 2 is bent at the center in the width direction, and the outer peripheral edge of the net body 1 is sandwiched and sewn between them. But the margin belt 2
Since the cord body that is continuous and woven in the longitudinal direction is extracted at the bent portion 2a at the center in the width direction, the bent portion 2a can be easily bent without bulging and twisting. .

Furthermore, by attaching the edge band 2 to the net body 1 by zigzag stitching, the seam can be adapted to expansion and contraction, and the edge band 2 does not easily come off from the net body 1 due to expansion and contraction. .

Further, since the net body 1 is formed in a knot-like shape in the mesh portion rather than in a knot-like shape, it has a good appearance and can be improved in design.

When the elastic net having such a structure is used as a small compartment for the back portion of the seat back, the difference in tensile ratio between the four pieces and the square is reduced, so that the rectangular shape is obtained when the square is pulled. Since it can be evenly stretched, the stretchable net can be evenly stretched in a rectangular shape on the rear surface of the seat.

The elastic net described above can be used not only as an accessory case for the back portion of the seat back but also for fixing luggage. In this case, although not shown, an engaging hole such as an eyelet is provided at a desired position (for example, the center or square of each piece) of the edge band 2 sewn on the outer peripheral edge of the net body 1. Then, the hook 3 is attached to the engagement hole, the baggage is covered with the net body 1, and the hook 3 is hooked on the predetermined locking portion 4 in a state where at least the square is pulled.
Since the difference in tensile ratio between the four pieces and the square of the net body 1 is reduced, the four pieces are not greatly distorted as shown in FIG. 5, and the net body 1 is fixed so as to cover the luggage. It becomes possible.

Therefore, when it is used for fixing luggage, since the difference in the expansion ratio between the four pieces and the square is reduced, the distortion of the four pieces is reduced, so that the net body 1 should cover the luggage. Thus, the luggage can be sufficiently fixed in the vertical and horizontal directions.

[0026]

As described above, since the stretchable net according to the present invention is formed by bulging the four pieces of the net body formed on the basis of the rectangular shape to the outside, the four pieces and the square are pulled. The difference in the rate is reduced, and when the square is pulled, it can be stretched evenly in a rectangular shape. Further, by attaching a stretchable edge band to the outer peripheral edge of the net body, it is possible to reduce distortion of the net body that may occur when the square is pulled.

When the edge band is attached to the outer peripheral edge of the net body, the edge band is bent at the center in the width direction, and the outer peripheral edge of the net body is sandwiched and sewn between the edge band to expand and contract the edge. The belt 2 does not easily come off from the net body 1.

Further, by pulling out the cord body which is continuous and woven in the longitudinal direction at the widthwise center of the edge band and bending the portion, the bent portion does not swell and twist, and it is easy. Can be folded.
