The upper and lower sheets 12 and 13 are all made of a synthetic resin such as a thermoplastic polyester (PE) or nylon of a known vinyl type and may be formed into a laminated form of a textile fabric or a net, It is possible.

A method of sealing and bonding the rims of the upper and lower sheets 12 and 13 may be a thermal fusion bonding method, a high frequency bonding method, or the like.

The mat main body 10 is provided with a valve for injecting air into the air filling part 11 when in use and discharging air from the air filling part 11 when not in use.

The valve may be a variety of known valves used for air injection and exhaustion. Depending on the type of the valve, the air inlet and the air outlet may be provided as a single valve, or the air inlet and the air outlet may be formed as separate valves And an air inlet 15 and an air outlet 16 formed in a separate valve structure can be identified.

The valve V1 provided in the air inlet 15 is capable of injecting air using an air pump or the like and the air injected into the air filling port 11 when the air pump is removed from the air inlet 15 A valve is used to prevent leakage to the outside.

7, the valve V1 provided in the air inlet 15 according to the present invention includes an air inlet 15 and an air inlet pipe 15A accommodated in the mat 10, A fixing part 15B connected to the air injection pipe 15A for sealingly fixing the air injection valve to the upper seat 12 or the lower seat 13 and a cap 15 for sealing the air injection pipe 15A, Member 15C.

The fixing portion 15B is formed of a general flange structure or a streamlined wing structure (the fixing portion of the general flange structure is shown in the figure), so that the volume of the mat main body 10 before air injection is kept to a minimum, Preferably does not interfere with the overall shape of the mat main body 10.

In addition, the air injection valve V1 having the air leakage preventing member 15D as described above is exemplarily described in the present specification. In addition, a known check valve type in which gas or fluid is restricted to flow in only one direction, Korean Patent No. 10-0947501 (2010.03.08.) Which is filed and registered by the applicant, "Buffer packing bag" or Korean Patent No. 10-1279167 (2013.06.20.) " Packing bag ", or a method disclosed in Korean Patent No. 10-1084301 (November 10, 2011)" Buffer packing bag with continuous heat-resistant member "can be used,

Therefore, the essence of the air injection valve in the present invention is a concept involving a valve having an air leakage preventing means for preventing air from leaking when the air pump is removed, so that the right interpretation of the present invention should not be limited.

On the other hand, the air discharge valve V2 constituting the air discharge port 16 shown in FIG. 2 is a form in which a general cap member (not shown) is fastened and closed. When the cap member is removed, A spout cap (not shown) may be used as a representative.

2 to 6, the supporting wall body 20 built in the air filling part 11 of the mat main body 10 is made of the same material as the upper and lower sheets 12 and 13, And is bonded to the upper and lower sheets 12 and 13 through the first and second adhesive portions 20a and 20b in the air filling portion 11 of the mat main body 10, do.

The support walls 20 are arranged at a predetermined interval on the air filling part 11 so that the air is injected into the air filling part 11 (or after the air is exhausted after use) Each of the support walls 20 is laid on one side or both sides of the support walls 20a and 20b to prevent the thickness of the mat main body 10 from increasing,

As the mat main body 10 is inflated during air injection, the supporting wall 20 is erected so that the air filling part 11 is partitioned into a plurality of air cells C while the air between the upper and lower sheets 12, .

At this time, the supporting wall 20 is formed to be shorter than the width (horizontal or vertical) in the same direction arranged in the mat main body 10, and a space in which the supporting wall 20 is not provided at the time of air- C) in which air can flow through the air communication portion 17 (see the enlarged perspective of FIG. 2).

Accordingly, when air is injected into the air filling unit 11 through the air inlet 15, air is simultaneously supplied to all the air cells C through the air communicating unit 17 to expand the mat main body 10, As a result, the support wall 20 is erected and expanded to form a kind of blocking wall between the adjacent air cells C, thereby suppressing the temperature transfer between the air cells C, and at the same time, The upper and lower seats 12 and 13 are prevented from being inflated by the expansion of the upper and lower supports 12 and 20a and the upper and lower sheets 12 and 13 through the upper and lower sheets 12 and 20b, The upper and lower seats 12 and 13 have a structure in which each of the lower seats 13 protrudes in a pseudo-semicircular shape, thereby ensuring the buffering ability, the supporting force, and the elastic restoring force of the upper and lower seats 12 and 13.

That is, in the conventional air mat shown in FIG. 1, when the user sits or lays on the upper surface of the air mat, the air chamber 3 is pressed by the bending and weight of the body, (Although not shown in the drawing, generally, in the case of the air mat shown in Fig. 1, air is injected into the air chambers 3 to fill all the air chambers 3 with one air infusion) The supporting force due to the air pressure filled in the air mat M disappears and the supporting force due to the air pressure at the site where the divisional bonding line 4 is formed is reduced In contrast to the structure which can not be operated at all,

Since the upper and lower seats 12 and 13 are connected to each other through the support wall 20 and the upper and lower seats 12 and 13 are prevented from expanding beyond a certain degree, So that the air pressure due to the pressurization is suppressed and the air pressure at the depressed portion is maintained at a predetermined level or higher. As a result, the supporting force of the entire air mat M is improved.

The present invention is characterized in that the first and second adhesive portions 20a and 20b for bonding the supporting wall 20 and the upper and lower sheets 12 and 13 are formed at a time through a single sealing operation, The heat resistant member 21 is applied to one or both of the inner surfaces of the upper wall portion 20A and the lower wall portion 20B which are in contact with each other in the wall 20.

The detailed structure and effects using this will be described later in detail.

The supporting wall 20 may be composed of a double wall 22 or a single wall 25 depending on the use of the air mat M. First of all, the supporting wall 20 made of the double wall 22 will be described ,

4, the support wall 20 includes a first sheet 23 constituting the upper wall portion 20A, and a second sheet 23 constituting the upper wall portion 20A. (22) having a third adhesive portion (27a) in which both side ends of the first and second sheets (23) and (24) are bonded to each other and a second sheet (24) Respectively,

The heat-resistant member 21 is provided at the center of one or both of the inner surfaces of the first and second sheets 23 and 24.

Therefore, as shown in [B] of FIG. 4, before the air is injected into the air filling part 11, the supporting wall 20 is divided into the first and second sheets 23 and 24, 20b are laid flat on both sides with respect to the adhesive portions 20a, 20b,

As shown in [C] of FIG. 4, when the air is injected, the upper and lower sheets 12 and 13 are expanded upward and downward, and the first and second adhesive portions 20a and 20b, The first sheet 23 functions as the top wall portion 20A of the supporting wall 20 and the second sheet 24 functions as the top wall portion 20A of the supporting wall 20 while the sheets 23 and 24 stand upright, And functions as the lower wall portion 20B of the support wall 20. [

Next, the supporting wall 20 made of the single wall 25 will be described.

5, the supporting wall 20 is folded with respect to the central folding line 25a of the single sheet, and the upper wall portion 20A and the lower wall portion 20B are constituted,

The heat-resistant member 21 is provided on the upper surface of the upper wall 20A and the lower surface of the lower wall 20B.

Therefore, before the air is injected into the air filling part 11, the upper wall part 20A and the lower wall part 20B of the supporting wall 20 are folded and bent in one direction with respect to the center folding line 25a ,

When the air is injected, the upper and lower sheets 12 and 13 are expanded upward and downward, and the single sheet is erected by the first and second adhesive portions 20a and 20b to complete the single wall 25.

2 and 6, the supporting wall 20 includes a wing portion 27 extending in both lateral directions at a central height connecting the upper wall portion 20A and the lower wall portion 20B The wing portion 27 divides the air cell C adjacent to the supporting wall body 20 into upper and lower spaces.

The support wall 20 also includes an auxiliary wing 28 extending forward and backward from each of the wing portions 27 so that the auxiliary wing 28 is in fluid communication with the adjacent support wall 20, And divides the portion 17 into upper and lower spaces.

Therefore, the present invention is effective in securing the heat insulating effect and the supporting force between the air cells C through the support wall 20, and at the same time, the inside of the air mat M through the wing portions 27 and the auxiliary wing portions 28, It is possible to prevent air convection between the upper and lower spaces of the air filling part 11, thereby maximizing the heat insulating property and the warming property of the air mat M.

That is, when the user lays down or sits on the air mat M, the upper space of the air mat M in contact with the body is raised in temperature, and the lower space of the air mat M in contact with the floor, Since the temperature of the upper space of the air cell C whose temperature is raised by the support wall 20 is not transferred to the upper space of another adjacent air cell C whose temperature has not been raised, Improved,

Furthermore, since the heat of the upper space of the air cell C is not transmitted to the lower space while the cooling air coming from the floor is blocked by the wing portion 27 and the auxiliary wing portion 28, .

At this time, when the air filling of the mat main body 10 is completed, the air filling portion near the front and rear frame adhering portions, that is, the air communicating portion 17, is hemispherical so that the supporting wall 20 is preferably not formed In addition, considering that air is filled in all the air cells C through one air injection, it is more preferable that the air communicating unit 17 does not partition the cells C in the left and right sides.

Since the specific structure for forming the wing portion 27 and the auxiliary wing portion 28 depends on the double wall 22 or the single wall 25, the manufacturing method described below will be described in detail.

Next, a manufacturing method of the air mat M according to the present invention will be described with reference to Figs. 3 to 6. Fig.

The manufacturing method of the air mat (M)

First, in step A), the upper and lower sheets 12 and 13 are cut to the same size according to the use of the air mat M in step S1.

At this time, in order to superimpose the upper and lower sheets 12 and 13 at the correct positions, it is preferable to adhere one edge portion of the upper and lower sheets 12 and 13, but the order of adhesion of the edge portions may be different, The upper and lower seats 12 and 13 are not physically separated from each other and the upper surface of the air mattress M constituting the upper surface of the upper sheet 12, The portion constituting the bottom surface of the air mat M means the lower sheet 13,

And the upper and lower sheets 12 and 13 by folding a single sheet cut in a predetermined length in half so that the order of edge bonding is not related to the essential characteristics of the present invention. It will not be limited.

And A) step S1) includes printing a reference line for the step C) on the upper sheet 12 or the lower sheet 13. [

That is, the reference line on which the supporting wall 20 is to be adhered is previously printed on any one of the upper and lower sheets 12, 13 (the lower sheet 13 in the figure), and in the step C) If the heat resistance member 21 is disposed so as to overlap with the baseline and then the step D) is carried out in the step S4, adhesion failure or the like can be prevented.

The reference line may include a vertical reference line L1 on which the heat resistant member 21 is fitted and a horizontal reference line L2 on which the support wall 20 is disposed to match the front and rear air communication parts 17 and the like.

When the double wall body 22 is employed as the supporting wall body 20 in step B) S2 of preparing the supporting wall body 20 to which the heat resistant member 21 is applied,

3 and 4, the step B) includes a step of aligning the first and second sheets 23 and 24 with a length corresponding to the interval between the horizontal reference lines L2, L1) to the width appropriate for the interval between the cuts,

The heat resistant member 21 is applied along the center of one surface of one of the first and second sheets 23 and 24 or one surface of both sheets.

The heat resistant member (21) may be formed in such a manner that a heat resistant ink having heat resistance is applied.

When the first and second sheets 23 and 24 thus prepared are superimposed on each other with the surface on which the heat resistant member 21 is formed facing the inner side and then the both ends are bonded to form the third adhesive portion 27a, Step B) is completed.

At this time, when the wing portion 27 and the auxiliary wing portion 28 are employed in the double wall body 22, in the step B), when the first and second sheets 23 and 24 are cut, (That is, the width of the adjacent two air cells C) in consideration of the width of the wing portions 27 (that is, the half width of each of the air cells C), the center heat- A third adhesive portion 27a to which the first and second sheets 23 and 24 are adhered in conformity with the expansion height of the air cell C is formed on both sides of the double wall member 22, 27 are provided.

Although it is not shown in the drawing, in step B), when cutting the first and second sheets 23 and 24 and cutting the lower and upper sheets 12 and 13 along the entire front and rear lengths, The front and rear portions of the heat resistant member 21 are cut by the length between the front and rear ends of the upper and lower sheets 12 and 13 and the horizontal reference line L2 to form a cutout 15a The auxiliary wings 28 are provided on both sides of the cutouts 15a and extend from the wings 27. Even if the double wall 22 is upright, (28) can be maintained in a horizontal state without standing upright.

The heat resistant members 21 of the plurality of supporting walls 20 made of the double wall body 22 after the step B) through the step S2 in the step C) are arranged at regular intervals in accordance with the vertical reference line L1 The wing portion 27 and the auxiliary wing portion 28 are arranged so as to overlap with the wing portion 27 and the auxiliary wing portion 28 of the other adjacent supporting wall 20 Only one support wall is shown for convenience).

Next, the mat main body 10 and the supporting wall 20, in which the upper sheet 12, the plurality of supporting walls 20, and the lower sheet 13 are sequentially stacked in step D) A first bonding portion 20a to which the upper sheet 12 and the upper wall portion 20A are bonded and a second bonding portion 20b to which the lower sheet 13 and the lower wall portion 20B are bonded, (20b) at one time.

That is, in the air mat M of the present invention, the first and second adhesive portions 20a and 20b are located on the same line in the vertical direction in order to secure a supporting force through the uprighting of the supporting wall body 20 The upper and lower sheets 12 and 13 and the supporting wall 20 between them are overlapped with each other when the air mat M is manufactured. do.

However, considering the general seal bonding method, the thermoplastic resin sheet is heated and heated by the heating of the heater, so that the first and second adhesive portions 20a and 20b are arranged on the same line The upper sheet 12, the upper wall portion 20A, the lower wall portion 20B, and the lower sheet 13 are brought into contact with each other by a single sealing operation with respect to the first and second adhesive portions 20a and 20b They are all bonded one at a time, and when the bonding is performed in this way, the standing up of the supporting wall 20 can not be guaranteed.

The top sheet 12 and the top wall portion 20A of the supporting wall 20 are primarily bonded to each other so as not to bond the supporting walls 20 to each other The lower sheet 13 and the lower wall portion 20B of the supporting wall 20 can not be bonded to each other.

Particularly, according to the above-described method, when a process of manufacturing a product by adhering vinyl sheets is consecutively carried out in a state in which the sheets are overlapped and adhesion of the adhesive portion proceeds through one adhesive machine, It is impossible to continuously and automatically adhere the supporting wall body 20 uprighted at the time of injection, so that it is required to work through a separate manual work, resulting in a disadvantage that the productivity is very low.

However, the present invention can be applied to the case where one or both of the inner surfaces of the upper wall portion 20A and the lower wall portion 20B on which the first and second adhesive portions 20a and 20b are in contact with each other, The heat resistant member 21 is applied to a part of the heat resistant member 21 so as to prevent adhesion between the surface to which the heat resistant member 21 is applied and the other surface to be contacted in the single seal bonding, (20) can be adhered and fixed to the mat main body (10).

Next, in step B), when the single wall 25 is employed in the step of preparing the supporting wall 20 to which the heat resistant member 21 is applied,

As shown in FIGS. 3 and 5, after a single sheet is cut into a width corresponding to the interval between the horizontal reference lines L2 and a width corresponding to the interval between the adjacent vertical reference lines L1, The heat resistant member 21 is applied to one end or both end of the one surface.

When the single sheet thus prepared is folded on the basis of the center folding line 25a so that the heat resistant member 21 faces the inner side, the step B) is completed.

Although not shown in the drawing, the single wall 25 (including the wing portion 27 and the auxiliary wing portion 28) 25 (shown in FIG. 5C only for the sake of convenience of explanation) , The sheet powder (not shown) cut in consideration of the width of the wings 27 in step B) is applied to the center of both sides of the single wall 25, that is, the center fold line 25a , And then the heat resistant member 21 of the single wall 25 is folded so as to be positioned on the inner side.

At this time, when the wing portion 27 is used, the end portions of the one wing portion 27 come into contact with each other between the end portion of the upper wall portion 20A and the end portion of the lower wall portion 20B, The heat resistant member 21 is applied to both the end portion of the lower wall portion 20B and the end portion of the lower wall portion 20B.

If the sheet powder is cut to fit the entire length of the upper and lower sheets 12 and 13 and then adhered to both sides of the single sheet in the step B) Since the auxiliary wing portion 28 is provided, when the single wall 25 is erected, the auxiliary wing portion 28 can be held in a horizontal state without being erected.

The heat resistant member 21 of the plurality of supporting walls 20 composed of the single wall 25 through the above step B) in the step C) in the step B) Are arranged at regular intervals in accordance with the vertical reference line L1.

Next, the mat main body 10 and the supporting wall 20, in which the upper sheet 12, the plurality of supporting walls 20, and the lower sheet 13 are sequentially stacked in step D) A first bonding portion 20a to which the upper sheet 12 and the upper wall portion 20A are bonded and a second bonding portion 20b to which the lower sheet 13 and the lower wall portion 20B are bonded, The partitioning of the upper and lower spaces through the erecting of the supporting wall 20 and the wing portion 27 and the auxiliary wing portion 28 at the time of air injection is completed, It is possible to manufacture an air mat M having the above-

As described above, the step of sealing and bonding all the edges of the mat main body 10 and the step of adding the air injection and discharge valves, etc. among the manufacturing methods of the air mat according to the present invention are well known in the art, The description of the steps is omitted, and the order of the step omitting the description is not related to the order of the manufacturing method of the present invention.

While the present invention has been described with reference to the accompanying drawings, it is to be understood that the invention is not limited thereto. Various modifications, alterations, and changes may be made by those skilled in the art. And substitutions are to be construed as falling within the scope of protection of the present invention.
