The present invention divides the double spaces constituting the air structure into a plurality of compartments through bonding, and removes the fiber yarns inside some of the double spaces among the divided parts so that the part from which the fiber yarns are removed is freely swollen by air injection. By doing so, it relates to an air structure using a double space that enables the production of air structures having various shapes and functions. First, an air structure 100 using a double space according to the present invention (hereinafter referred to as'air structure 100' ) Is divided into a plurality of areas by the junction 120, and the divided areas are divided into a first area 130 and a second area 140.

That is, the double space used in the manufacture of the air structure 100 is generally an adhesive sheet connected to the edge portion between the upper sheet 110a and the lower sheet 110b, and the upper sheet 110a and the lower sheet 110b. When the outer shape is made in (110c), and a number of strands of fiber yarn 160 are closely connected in the vertical direction between the upper sheet 110a and the lower sheet 110b, and air is injected into the inside of the double space, the fiber The shape of the double space is maintained in a flat state by the yarn 160 and is configured to support the load from the outside by the fiber yarn 160.

The junction part 120 is formed by bonding the upper sheet 110a and the lower sheet 110b of the double space paper together. Even when air is injected into the double space paper, the upper sheet ( 110a) and the lower sheet (110b) are kept in a bonded state, the double space is partitioned by the bonding portion (120).

In this case, the bonding portion 120 may be formed by applying or attaching an adhesive means to the inner surfaces of the upper sheet 110a and the lower sheet 110b, but the bonding portion 120 is formed at the center of the double space or partially In the case of formation, it is not easy to apply or attach the adhesive means to the correct location, and the adhesive force of the adhesive means decreases over time, causing a problem that the joint state of the joint 120 cannot be maintained. Therefore, it is preferable to form the bonding portion 120 by sewing rather than bonding means.

In other words, after overlapping the upper sheet (110a) and the lower sheet (110b) without injecting air into the double space, by sewing the position to form the joint (120), the joint ( 120) can be formed.

In addition, the sewing operation for forming the joint 120 may be performed two or more times at predetermined intervals, which allows the joint 120 to have a width of more than a predetermined thickness, so that the division of the double space by the joint 120 is more This is to ensure that the incision 122 to be described later can be formed while ensuring that it can be made.

At this time, the reinforcing sheet 150 is attached to the outer surface of the joint 120, that is, the outer surface of the upper sheet 110a and the lower sheet 110b corresponding to the joint 120, the reinforcing sheet 150 By reinforcing the outer surface of the joint 120, it serves to prevent air from leaking or water from penetrating through the joint 120 during use of the air structure 100.

That is, by attaching the reinforcing sheet 150 additionally to the upper and lower portions of the joint 120 having a width greater than or equal to a predetermined thickness by sewing, the joint 120 is prevented from being exposed to the outside and at the same time It is configured to prevent air from leaking or water from seeping through the seam line of the joint portion 120 formed by the seam.

In addition, the reinforcing sheet 150 has a fine amount that can be introduced into the joint 120 through the gap between the sewing lines when air is injected into the air structure 100 by increasing the thickness of the joint 120 It also serves to prevent the shape of the junction 120 from being deformed by air.

On the other hand, the double space zone divided by the junction 120 may be divided into one or more first zones 130 and one or more second zones 140, wherein the first zone 130 is an inner, that is, an upper portion. The fiber yarn 160 exists between the sheet 110a and the lower sheet 110b, and is configured to exhibit the same shape and function as the existing double space, and the second zone 140 is inside, that is, the upper A portion from which the fiber yarn 160 between the sheet 110a and the lower sheet 110b is removed. Since the fiber yarn 160 does not exist, when air is injected into the second zone 140, the second zone ( The shape of 140) can be freely swollen without limitation by the fiber yarn 160.

That is, conventional air structures using double spaces are made in a uniform shape due to the limited deformation of the shape due to air injection by the internal fiber yarn 160, and the applicable products are limited and the purpose of use of the product. While it was not possible to properly implement the characteristics according to the present invention, in the present invention, the air structure 100 using the double space paper, the first zone 130 that can utilize the characteristics of the existing double space paper, and the internal fiber yarn 160 It is configured to be separated into a second zone 140 that is relatively free of shape deformation due to air injection, so that an air structure 100 having more various shapes and functions can be manufactured.

As an embodiment of such an air structure 100, an air mat 100a using a double space may be applied. As shown in FIG. 1, the air mat 100a is spaced apart from the edge by a predetermined distance so that the joint 120 ) Is formed in a square shape, and is divided into a first zone 130 on the inside and a second zone 140 on the outside based on the junction 120.

That is, as shown in Fig. 2, the first zone 130 constituting the central portion by forming the junction 120 inward a certain distance from the edge of the airmet 100a made of double spaces, and the first zone 130 constituting the edge portion After dividing into two zones 140, the fiber yarn 160 inside the second zone 140 is removed, and the first zone 130 corresponding to the inner side, that is, the central part, based on the junction 120 It is made of a body portion in which the fiber yarn 160 is present between the sheet 110a and the lower sheet 110b, and the second region 140 corresponding to the outer side, that is, the edge portion, is the upper sheet 110a and the lower sheet 110b. ) It is possible to manufacture the air mat (100a) using a double space made of the expanded portion 140, which is freely expanded by the fiber thread 160 is removed by air injection.

The air mat (100a) as described above, while the body portion corresponding to the first zone (130) can maintain a high support for the load, which is the advantage of the existing double space, while the expansion portion (140) corresponding to the second zone (140) Is capable of absorbing external shocks by acting as an air cushion, as well as playing the role of pillows or footrests, so that it can perform various shapes and functions compared to existing air mats made of double spaces. You will have the advantage of being.

In addition, as another embodiment of the air structure 100 according to the present invention, as shown in Figure 3, it is possible to manufacture a pet cushion or a house (100b), as in the above-described embodiment, with a double space The first zone 130 corresponding to the central part by forming the junction 120 inward a certain distance from the edge of the pet cushion or house 100b made is a fiber yarn between the upper sheet 110a and the lower sheet 110b Consisting of the main body where 160 is present, the second region 140 corresponding to the rim is freely expanded by air injection by removing the fiber yarn 160 between the upper sheet 110a and the lower sheet 110b It is possible to manufacture a pet cushion or a house (100b) consisting of the expansion part 140.

That is, as shown in FIG. 5, the central part where the pet is mainly located is formed as a body part corresponding to the first zone 130 so that the characteristics of the existing double space can be maintained, while corresponding to the second zone 140 By removing the inner fiber yarn 160 and forming the expanded part 140, the rim portion can be manufactured to improve the overall aesthetics and at the same time, allow pets to recognize it as a fence, so that they can feel more comfortable and stable. There will be.

At this time, the junction 120, that is, the junction 120 positioned between the body portion corresponding to the first zone 130 and the expansion portion 140 corresponding to the second zone 140 is partially incision ( 122) may be formed, and the cutout portion 122 serves to separate the body portion and the expansion portion 140 from each other.

That is, as shown in (b) of FIG. 4, the joint 120 positioned between the body portion and the expansion portion 140 is formed to have a predetermined width through two stitches that are spaced apart from each other by a predetermined distance, and A junction part connecting the lower part of the body part and the expansion part 140 by forming cutouts 122 in the remaining parts except for the lower part, that is, the left, right and upper junction parts 120 having a width of The body part and the expansion part 140 are spaced apart from each other by the cutouts 122 formed on the left, right and upper sides while maintaining the state of being connected to each other by the body part and the expansion part 140 by 120). It is possible to manufacture the air structure 100 having more various shapes or functions by allowing the body portion or the expansion portion 140 to rotate as an axis.

On the other hand, as another embodiment of the air structure 100 according to the present invention, a boat 100c or a board (hereinafter, limited to'boat 100c') used for water leisure such as an air boat and a paddle board will be described. In this case, as shown in (a) and (b) of Fig. 6, the junction 120 is spaced a predetermined distance from the center of the boat 100c formed as a double space in the left and right directions. So that it can be formed in the longitudinal direction.

That is, a body portion corresponding to the first zone 130 is formed in a central portion positioned between the junction portions 120, and a second zone 140 outside of the junction portion 120 corresponding to both left and right sides of the body portion. ) Corresponding to the first and second expansion parts 140a and 140b, respectively, so that the supporting power of the boat 100c can be improved by the body part made of a double space, while the first and second expansion parts 140a It is configured to improve stability by increasing buoyancy by 140b).

At this time, the first and second expansion parts 140a and 140b may be formed to increase their diameter from the front to the rear when air is injected into the inside, which improves the stability and driving performance of the boat 100c. This is to make it possible to do it.

That is, in the case of the boat 100c, it is usually designed so that the center of gravity is slightly rearward from the center, and people who actually board the boat 100c also board at the rear rather than the front of the boat 100c. As shown in (a), the diameter of the first and second expansion portions 140a and 140b formed in the longitudinal direction of the boat 100c increases toward the rear of the boat 100c so that stability can be improved. It is composed.

In addition, when the front diameters of the first and second expansion parts 140a and 140b are reduced as described above, the resistance of water applied to the boat 100c during driving is reduced, thereby improving the running performance of the boat 100c. .

On the other hand, in this embodiment, that is, when the air structure 100 is a boat 100c, as described above, it is preferable that the diameters of the first and second expansion parts 140a and 140b increase from the front to the rear. However, in the case of an air structure 100 other than the boat 100c, when air is injected into the expansion part 140 formed in the longitudinal direction, the diameter may be configured to decrease from the front to the rear. to be.

In addition, even when the expansion part 140 is formed in a direction other than the longitudinal direction, that is, in a width direction, a radial direction, a circumferential direction, etc., the expansion part 140 may be configured to have different diameters, and the expansion part 140 Even if it is formed in a curved shape rather than a straight shape, the diameter may be configured to be different from each other, and a detailed method for this will be described later.

Next, as shown in (b) and (c) of FIG. 7, the expansion part 140 corresponding to the second zone 140 is formed in the center of the main body rather than outside including the left and right sides of the main body. The expansion part 140c formed in the center of the main body part (hereinafter referred to as'the third expansion part 140c') may be formed independently of the expansion part 140 formed outside the main body part. .

In other words, after forming the junction 120 in a closed structure so that a specific shape is formed inside the body portion corresponding to the first zone 130, the fiber yarn 160 inside the junction 120 By removing the, it is possible to form a third expanded part 140c independent of the expanded part 140 formed outside the main body.

At this time, the third inflation part 140c may be formed in various shapes, such as a straight type or a curved type, and in the case of the boat 100c, it is formed to protrude downward from the lower seat 110b in a wedge shape that divides the current It may be formed to protrude to the top of the upper sheet (110a) in the shape of the support portion supporting the rear portion of the.

In addition, although not shown, the first zone 130 and the second zone 140 corresponding to the main body part and the expansion part 140 are respectively formed with air inlets for injecting air into the inside, and the first zone ( When the 130) and the second zone 140 each form a plurality of zones, it goes without saying that an air inlet must be separately formed in each zone.

On the other hand, as described above, the method of manufacturing an air structure using a double space paper according to the present invention uses the double space paper as the first zone 130 corresponding to the body part and the second zone corresponding to the expansion part 140 ( It relates to a method for manufacturing an air structure 100 that can be divided into 140), and its configuration is largely a double space processing step (S10), a joint forming step (S20) and an expansion part as shown in FIG. It comprises a forming step (S50).

First, the double space paper processing step (S10) relates to the step of processing the double space paper in the shape of the air structure 100 to be manufactured, and is the same as the process of manufacturing the air structure 100 using the conventional double space paper. Do.

That is, the sheet 110 is cut into the shape of the air structure 100 to be manufactured and bent to form a body shape, and a number of fibers made of polyester or the like are formed between the upper sheet 110a and the lower sheet 110b. When the yarns 160 are bonded by a method such as thermal fusion, and the adhesive sheet 110c is bonded to the upper portion of the bonded area, that is, the side edge of the bonded state, the shape of the air structure 100 made of a double space paper is completed. .

Next, the junction forming step (S20) relates to the step of forming the junction 120 for partitioning the double space processed in the shape of the air structure 100, the junction 120 as described above, the air structure It plays a role of dividing (100) into a first zone (130) and a second zone (140).

That is, after determining the position of the joint 120 to be divided into the first zone 130 and the second zone 140 in consideration of the overall shape and function of the air structure 100 to be manufactured, the determined joint 120 The upper sheet 110a and the lower sheet 110b corresponding to the position of are joined by sewing to form the joint 120 that divides the air structure 100.

In this case, as described above, the joint portion 120 may be formed to have a predetermined width according to the diversification of the shape and function of the air structure 100 to be manufactured or the purpose of use. In this case, As a result, the seam lines are formed to be spaced apart from each other by a predetermined distance, thereby forming the joint 120 having a predetermined width.

On the other hand, after the bonding portion forming step (S20), the reinforcing sheet bonding step (S30) is further performed, and the reinforcing sheet bonding step (S30) is an outer surface of the bonding portion 120, that is, an upper sheet corresponding to the bonding portion 120 By attaching the reinforcing sheet 150 to the outer surface of the lower sheet 110a and the lower sheet 110b to reinforce the junction 120, air leaks or water seeps through the junction 120 during use of the air structure 100. At the same time, it serves to minimize the deformation of the shape of the joint 120 by increasing the thickness of the joint 120 while preventing the lifting.

In addition, after the reinforcing sheet bonding step (S30), a cutout forming step (S40) of forming a cutout 122 by cutting part of the joint 120 to which the reinforcing sheet 150 is bonded may be further performed. , As described above, the cutout 122 maintains a state in which the main body portion corresponding to the first zone 130 and the expansion portion 140 corresponding to the second zone 140 are connected to each other, By making it possible to rotate the body part or the expansion part 140 having the uncut joint 120 as an axis by being spaced apart, it is possible to manufacture the air structure 100 having more various shapes or functions.

At this time, the width of the cut-out part 122 is to be smaller than the width of the joint part 120, and more specifically, the cut-out part 122 is formed by cutting the space between the outermost seams formed in the step of forming the joint part 120 It is preferable that the sheet 110 corresponding to the first region 130 or the second region 140 is not damaged and at the same time minimizes additional processing after the incision 122 is formed.

Next, in the step of forming the expansion part (S50), at least one part of the parts partitioned by the junction part 120, that is, a part corresponding to the second zone 140 is selected and freely expanded by injecting air into the interior. It relates to the step of forming the expansion part 140, by removing the fiber yarn 160 installed inside the second zone 140 selected in consideration of the shape and function of the air structure 100 to be manufactured 140) can be formed.

In more detail, the expansion part forming step (S50) includes a fiber yarn removing step (S54) and a bonding process step (S56), and first, the fiber yarn removing step (S54) is a second zone of the double space paper. (140) Relates to the step of removing the fiber yarn 160 existing inside, by cutting the fiber yarn 160 connected between the upper sheet (110a) and the lower sheet (110b) of the second zone (140) By removing, the sheet 110 forming the second zone 140 can be expanded freely by injecting air into the inside.

At this time, in the fiber yarn removing step (S54), the fiber yarn 160 inside the second zone 140 may be partially removed. When the fiber yarn 160 is partially removed, the fiber yarn 160 is removed. Since the expansion by air injection is made only in the part, the expansion part 140 can be formed in a more diverse shape.

In addition, it is of course possible to adjust the degree of expansion due to air injection by adjusting the number of the fiber yarns 160 removed in the fiber yarn removing step (S54).

Next, the bonding processing step (S56) relates to a step of re-bonding the sheet 110 that is opened and opened on one side after the fiber yarn removing step (S54) is completed, and the upper portion of the sheet 110 cut in the longitudinal direction The and the lower part are overlapped or are in contact with each other and then joined to make a more robust joint.

At this time, it is preferable to additionally bond an adhesive sheet 110c or a reinforcing sheet to the outside of the bonded portion to reinforce the strength of the bonded portion and at the same time improve durability.

In addition, in the joining processing step (S56), the amount of overlap at the front end and the rear end of the cut portion may be different from each other to be joined, which is, when air is injected into the inside, the expansion portions at the front and rear ends ( 140) is to be different from each other.

That is, in consideration of the shape or functional aspect of the air structure 100 to be manufactured, there are cases where it is necessary to increase or decrease the diameter of the expansion part 140 from the front to the rear. In this case, the bonding processing step ( The amount of overlap at the front end and the rear end of the portion cut in S56) is different from each other so that a gradual change in diameter of the expansion unit 140 is possible.

In more detail, in the process of joining the cut portions, in the case of joining by increasing the overlapping width of the sheets 110 at the front end and narrowing the overlapping width of the sheets 110 at the rear end, The diameter of the expansion part 140 formed by the air injection of the air increases toward the rear, and on the contrary, the width at which the sheet 110 overlaps at the front end is narrowed, and the width at which the sheet 110 overlaps at the rear end In the case of widening and bonding, since the diameter of the expansion part 140 decreases toward the rear, it is possible to manufacture the air structure 100 having more various shapes or functions.

At this time, in order to change the diameter of the expansion part 140, the amount of overlapping at the front and rear ends of the cut part in the bonding process as described above may be different, but in the cutting process step S52, the sheet 110 The diameter of the expansion part 140 may be changed by adjusting the cutting width.

That is, when there is no change in the diameter of the expansion unit 140, the sheet 110 is cut in a straight line in the longitudinal direction, and when the diameter of the expansion unit 140 is changed in the longitudinal direction, the sheet 110 is moved in the longitudinal direction. In the state of cutting in a straight line, cutting starts from a part with a large diameter, increases the width to be cut toward a part with a small diameter, and cuts it again to equalize the amount of overlap of the cut part in the joint processing step (S56). While making it possible, the diameter of the expansion part 140 formed by air injection may be formed to gradually change in the longitudinal direction.

Therefore, according to the air structure using the double space paper according to the present invention as described above, the double space paper constituting the air structure 100 is divided into a plurality of divisions through bonding, and the divided area is divided into a fiber yarn 160 inside. The second zone 140 from which the fiber yarn 160 is removed is divided into a first zone 130 where) is present and a second zone 140 from which the fiber yarn 160 is removed. By allowing it to swell freely, it is possible to manufacture the air structure 100 having various shapes and functions, and not only can properly implement the characteristics according to the purpose of use of the product, but also the air structure 100 using double spaces. ) Can be manufactured to have a variety of shapes and characteristics, thereby satisfying the needs of various consumers.

The above-described embodiments have been described with respect to the most preferred examples of the present invention, but are not limited to the above embodiments, and the characteristic technical content of the present invention can be applied to air structures using various double spaces not illustrated in the present invention.
