Description

The present invention relates to sandbags, and more particularly to sandbags that are easy to manufacture and easy to use.

Sandbags that are easy to manufacture are disclosed in Patent Document 1 below. This sandbag is formed by continuously forming a plurality of sandbags by weaving, and is formed by arranging the bottom of the lower end and the opening of the upper end of the sandbag in the weaving direction. The bottom of the sandbag is formed by weaving woven fabric as well as the edges on both the left and right sides. This bottom is set to a predetermined width in the weaving direction, and just below it forms a portion where the fabric is not woven.

There is also a statement that seeds and fertilizer should be glued to the inside of the sandbag in advance.

In use, it is cut at the bottom, where the fabric is not woven, and a separate cord is sewn in the vicinity of the opening to allow the opening to be closed.

This sandbag is easy to manufacture because it does not require sewing to attach a mouth cord when manufacturing the sandbag body. However, the cord must be attached by a separate operation at the time of use.

Jikkai Sho 64-622

It is a main object of the present invention to make it easy to manufacture without the need for sewing work and to make it easy to use by eliminating the need for a mouth strap threading work at the time of use.

The means for this is a clay sac made of a double woven fabric, which is formed by weaving a bag with warps and wefts, has an opening at one end, and has closures on three sides at all other ends. At the edge of the opening in each of the one woven structure and the other woven structure that overlap each other by weaving, the warp or the warp and weft of the edge are replaced with separate knots woven during the bag weaving. Alternatively, it is a non-sewn bag clay sac that is held in parallel with the warp and weft.

In this configuration, since the mouth cord is provided in advance, there is no special work to be performed when using it, and the opening is closed with the mouth cord after putting soil or the like. If necessary, one end of the cord may be tied or welded to fix it.

According to the present invention, since the mouth cord is held at the time of weaving, the sewing work is not required and the production can be facilitated, and the work of passing the mouth cord is not required at the time of use, so that the use can be easily performed.

An embodiment for carrying out the present invention will be described below with reference to the drawings.

This description mainly describes two types of non-sewn bag sandbags 11 (11a, 11b) (see FIGS. 1 and 9). Each of the non-sewn bag clay sac 11 is formed by weaving a bag with warp 12 and weft 13, and is made of a double woven fabric having an opening 14 at one end. At the edge of the opening 14 in the other woven structure 16, a mouth cord 17 woven during bag weaving is provided in parallel with the warp 12 or the weft 13.

First, the non-sewn bag sandbag 11a shown in FIG. 1 will be described.

FIG. 2 shows an enlarged state of the mouth cord 17 portion (A portion in FIG. 1) of the non-sewn bag sandbag 11a. As shown in FIGS. 1 and 2, the woven structures 15 and 16 of the non-sewn bag sandbag 11a are configured by using a monofilament for the warp 12 and a tape yarn or a flat yarn for the weft 13. The warp 12 and the weft 13 are made of synthetic resin.

A plurality of warp threads 12 are arranged in parallel at appropriate intervals, and the weft threads 13 are arranged orthogonally and parallel to the warp threads 12 and are sandwiched and held by the warp threads 12 from both the front and back sides.

The mouth cord 17 is wider (thicker) than the weft 13, and is woven in parallel with the weft 13. That is, when weaving two weaving structures 15 and 16 that overlap each other with the warp 12 and the weft 13, the portion provided with the mouth cord 17 is held through the mouth cord 17 instead of the weft 13. Therefore, the mouth cord 17 is sandwiched and held from both the front and back sides by the warp 12 like the weft 13.

The cord 17 is provided on one woven structure 15 and the other woven structure 16 that overlap each other.

The direction orthogonal to the extending direction of the mouth cord 17 is the weaving direction D of the weaving structures 15 and 16, and a plurality of non-sewn bag sandbags 11a are continuously formed in the weaving direction D. FIG. 3 is a surface view of the sandbag connecting body 31 to which the non-sewn bag sandbag 11a is connected.

The single non-sewn sandbag 11a and the plurality of integrated sandbags 31 are the "non-sewn sandbags" of the present invention, but for convenience, the plurality of non-sewn sandbags 11a are integrated. As described above, the sandbag connecting body 31 is referred to as a sandbag connecting body 31.

In the sandbag connecting body 31, a closed bottom portion 18 at the lower end of the non-sewn bag sandbag 11a and a portion serving as the opening portion 14 at the upper end are formed in a series. That is, the non-sewn sandbag 11a constituting the sandbag connecting body 31 is connected in the vertical direction by the warp 12 extending in the weaving direction D.

The disassembled state of the sandbag connecting body 31 is shown in FIG. As described above, the non-sewn bag sandbag 11a and the sandbag connecting body 31 are composed of one woven structure 15 and the other woven structure 16 that overlap each other, and two pieces are densely woven into the portions of the weaving direction D at regular intervals. The above-mentioned closed bottom 18 that integrates the woven structures 15 and 16 of the above-mentioned is formed. The closed bottom 18 is appropriately set to a length in the weaving direction D.

Further, on the left and right side portions in the width direction of the sandbag connecting body 31, weaving direction D, that is, a closed side portion 19 that integrates the two weaving structures 15 and 16 by tightly weaving along the longitudinal direction is formed. do. The closed bottom 18 is appropriately set to have a width in a direction orthogonal to the weaving direction D. These closed side portions 19 are discontinuous in the longitudinal direction by skipping the portion having the mouth cord 17.

In this way, the non-sewn bag sandbag 11a made of double woven fabric intermittently forms the closed bottom 18 and the closed side 19 in the weaving direction D when weaving the bag with the warp 12 and the weft 13. It is manufactured by a manufacturing method in which the mouth cord 17 is woven in synchronization with the above. The position where the cord 17 is woven is adjacent to the position where the closed bottom 18 is formed, and is the edge of the portion which later becomes the opening 14, and the weaving direction is parallel to the weft 13.

As shown in FIG. 5, the sandbag connecting body 31 having such a configuration is wound in a roll shape, distributed, and used. It may be folded into a zigzag shape or the like for distribution.

In addition to the above configuration, the non-sewn bag sandbag 11a has the following configuration.

The colors of the threads constituting the two front and back woven structures 15 and 16 are appropriately set, but in the case of vegetation sandbags, one of the woven structures 15 and 16 and the other woven structure 16 The main thread that constitutes one of them is black, and the main thread that constitutes the other is green. That is, since a monofilament is used for the warp 12 constituting the weaving structures 15 and 16 and a tape yarn or a flat yarn is used for the weft 13, the weft 13 is more exposed than the warp 12, and the weft structure 15 is exposed. , 16 are the main threads that make up. Whether or not it is the main yarn depends on the composition of the woven structures 15 and 16 and the yarn used, but it is judged by whether or not it appears in the table and has a large visual effect. The main thread may be composed of a plurality of threads.

FIG. 6 shows the woven structures 15 and 16 that overlap each other in a partially broken state. As shown in this figure, the weft 13 of the weaving structure 15 on one of the front and back sides is black, and the weft 13 of the other weaving structure 16 is green, and the colors that stand out are different for each of the weaving structures 15 and 16. Since the monofilament constituting the warp thread 12 is thinner than the weft thread 13, it can be composed of threads of an appropriate color such as black, white, and colorless (transparent).

Further, as shown in FIGS. 1, 3 and 4, the appropriate portion between the closed bottom portion 18 and the position of the cord 17 in the two woven structures 15 and 16 is a thread constituting another portion. Warp and wefts of different colors are inserted to form the reference line 21. The formation position of the reference line 21 is a position where the filling amount of the soil becomes an appropriate amount when the soil is put in with the closed bottom 18 facing down. The color of the reference line 21 may be, for example, yellow in order to make it easier to see when the color of the main threads of the woven structures 15 and 16 is black or green as described above.

Further, in the case of vegetation sandbags, seeds 22 are attached to at least one surface, that is, the outer surface of one woven tissue 15 or the other woven tissue 16, as shown in FIG. 7. The seed 22 is held by the adhesive 23. In the example of FIG. 7, an example of attaching to the surfaces of the woven structures 15 and 16 on both the front and back sides is shown. The attachment of the seed 22 is continuously applied to the long sandbag connecting body 31, and then the sandbag connecting body 31 is wound up in a roll shape.

The seed 22 is attached to the outer surface, but when used as the non-sewn bag sandbag 11a, the non-sewn bag sandbag 11a is turned upside down as shown in FIG. 8, and the outer surface to which the seed 22 is attached is turned inside. Then, the soil X is put in through the opening 14.

Next, the non-sewn bag sandbag 11b shown in FIG. 9 will be described.

FIG. 10 shows an enlarged state of the mouth cord 17 portion (B portion in FIG. 9) of the non-sewn bag sandbag 11b. Even in this non-sewn bag sandbag 11b, the weaving structures 15 and 16 are configured by using a monofilament for the warp 12 and a tape yarn or a flat yarn for the weft 13. The warp 12 and the weft 13 are made of synthetic resin. In FIG. 10, the left-right direction is the extending direction of the warp 12, that is, the weaving direction D, and the vertical direction is the extending direction of the weft 13.

A plurality of warp threads 12 are arranged in parallel at appropriate intervals, and the weft threads 13 are arranged orthogonally to the warp threads 12 in parallel, and are sandwiched and held by the warp threads 12 from both the front and back sides.

The mouth cord 17 is wider (thicker) than the warp 12 and the weft 13, and is woven in parallel with the warp 12. That is, when weaving two weaving structures 15 and 16 that overlap each other with the warp 12 and the weft 13, the mouth cord 17 is held through the weft 13 so as to be sewn in a zigzag manner on the front and back in an appropriate length. In FIG. 10, the mouth cord 17 is drawn centering on the portion of the woven structures 15 and 16 that changes from the back to the front or from the front to the back.

The cord 17 is provided on one woven structure 15 and the other woven structure 16 that overlap each other.

The direction in which the cord 17 extends is the weaving direction D of the weaving structures 15 and 16, and a plurality of non-sewn bag sandbags 11b are continuously formed in the weaving direction D. FIG. 11 is a surface view of the sandbag connecting body 31 to which the non-sewn bag sandbag 11b is connected.

Both one non-sewn sandbag 11b and a plurality of integrated sandbags 31 are the "non-sewn sandbags" of the present invention, and a plurality of non-sewn sandbags 11b are integrated. For convenience, the sandbag connecting body 31 is the same as described above.

In the sandbag connecting body 31, the left and right side portions of the non-sewn bag sandbag 11b are connected. That is, the non-sewn sandbags 11b constituting the sandbag connecting body 31 are connected in the left-right direction by the warp 12 extending in the weaving direction D.

Further, the sandbag connecting body 31 has a sandbag interstitial portion 24 having an appropriate length between the side portions of the non-sewn bag sandbags 11b. The sandbag space 24 is formed by skipping the weft 13. Therefore, the sandbag interstitial portion 24 is composed of only the warp 12.

The disassembled state of the sandbag connecting body 31 is shown in FIG. As described above, the non-sewn bag sandbag 11b and the sandbag connecting body 31 are composed of one woven structure 15 and the other woven structure 16 that overlap each other, and two pieces are densely woven into the portions of the weaving direction D at regular intervals. A pair of closed side portions 19 that integrate the woven structures 15 and 16 of the above are sequentially formed at regular intervals. The closed side portion 19 is appropriately set to a length in the weaving direction D.

The distance between the pair of closed side portions 19 corresponds to the width of the non-sewn sandbag 11b, and the distance between the pair of closed side portions 19 corresponds to the length of the above-mentioned inter-sandbag portion 24. ..

Further, a closed bottom portion in which two weaving structures 15 and 16 are integrated by weaving densely along the weaving direction D, that is, the longitudinal direction, on one of the left and right sides of the sandbag connecting body 31 in the width direction. 18 is formed. The closed bottom 18 constitutes the lower end of the non-sewn bag sandbag 11b. The closed bottom 18 is appropriately set to have a width in a direction orthogonal to the weaving direction D.

Then, an opening 14 is formed in the other of the left and right directions in the width direction of the sandbag connecting body 31 without weaving. The above-mentioned mouth cord 17 is woven between the warps 12 at the edge of the opening 14.

As described above, the non-sewn bag sandbag 11b made of double woven fabric is also intermittently closed in the weaving direction D when the warp and weft 13 are woven, like the non-sewn bag sandbag 11a shown in FIG. It is manufactured by a manufacturing method in which a mouth cord 17 is woven in synchronization with this bag weaving while forming a bottom portion 18 and a closed side portion 19. The position where the cord 17 is woven is the edge of the opening 14 formed on the opposite side of the closed bottom 18, and the weaving direction is parallel to the warp 12.

As shown in FIG. 13, the sandbag connecting body 31 having such a configuration is also wound in a roll shape, distributed, and used. It may be folded into a zigzag shape or the like for distribution.

In addition to the above configurations, the main yarn constituting one of the weaving structure 15 and the other weaving structure 16 constituting the double woven fabric shall be black, and the main yarn constituting the other shall be green (). (See FIG. 6), inserting a reference line 21 (see FIG. 1), and attaching the seed 22 to at least one surface of the one woven structure 15 or the other woven structure 16 (see FIG. 7). It is the same as the non-sewn bag sandbag 11a shown in FIG. The reference line 21 can be formed in a manner having a discriminating power in appearance, such as a thread having a different color from that of the threads of other portions and a plurality of threads having different spacings from those of the other portions.

In the non-sewn sandbag 11 having the above configuration, first, the wound sandbag connecting body 31 is pulled out to a required length and separated into each non-sewn sandbag 11. The non-sewn sandbag 11a of FIG. 1 is cut at a position immediately below the closed bottom 18 as shown by a virtual line in FIG. 3, and the non-sewn sandbag 11b of FIG. 9 is shown by a virtual line in FIG. It is cut at an appropriate position in the sandbag space 24 as described above.

After separating the non-sewn bag sandbag 11, turn it over so that the side to which the seed 22 is attached is on the inside, put the soil X through the opening 14 (see FIG. 8), and close the opening 14 with the mouth cord 17. .. Then, the non-sewn bag sandbag 11 is installed with the side mainly exhibiting green facing up.

After cutting the non-sewn bag sandbag 11, one end of the mouth cord 17 may be bound to each other, bonded with a fastener such as a metal fitting, or welded to be used as needed. In the case of welding, for example, an ultrasonic stapler can be conveniently used. Welding may be performed not only on one end of the mouth cord 17 but also on the woven structures 15 and 16.

As described above, the non-sewn bag sandbag 11 can be manufactured only by weaving even to hold the mouth cord 17. That is, the mouth string 17 is provided at the stage when the non-sewn bag sandbag 11 is woven, and can be used without sewing or threading. Therefore, it is easy to manufacture and can be used easily and quickly.

Further, since a plurality of the non-sewn bag sandbags 11 are continuously formed by the warp 12 and are distributed in this state, they are handled as compared with the case where the non-sewn bag sandbags 11 are separated. Is easy. When wound in a roll shape, management and the like become easier.

Further, since the seed 22 is attached to the surfaces of the woven structures 15 and 16, the attachment operation is easy. Moreover, since the sandbag connecting body 31 in which a plurality of non-sewn bag sandbags 11 are connected is formed, the seeds 22 can be attached in the middle of a series of steps from the weaving process to the winding process, for example. The work of attaching the seed 22 is easy. After the seed 22 is attached, the attached seed 22 can be easily protected by winding it in a roll shape.

The soil filling is performed with the surface to which the seed 22 is attached inside, but the reversing work is extremely easy. Since the seeds are installed after being inverted, it is possible to prevent the seeds 22 from falling off during the soil filling work and the installation work.

The above-mentioned configuration is one form for carrying out the present invention, and the present invention may adopt other configurations.

For example, the weaving structures 15 and 16 can be appropriately formed, for example, by using tape yarn or flat yarn for the warp 12 and the weft 13.

A plurality of non-sewn bag sandbags 11 may be connected, or may be individually separated after weaving and then distributed.

If it is not a vegetation sandbag, the attachment of seeds is omitted.
