[0035] Hereinafter, a guiding jig for manufacturing an inflatable mattress and an inflatable mattress manufacturing apparatus including the same according to an embodiment of the present invention will be described with reference to the drawings.

[0036] Figure 1FIG. is a view showing an air mattress manufactured by an air mattress manufacturing apparatus according to an embodiment of the present invention, and Figure 2 is Figure 1 a cross-sectional view of an edge portion of the air mattress shown.

[0037] Referring to Figure 1 and Figure 2 , the air mattress 10 manufactured by the air mattress manufacturing apparatus 1 (see Figure 3 ) according to an embodiment of the present invention may include: a mattress body 11 that is cut to match the size of the air mattress 10 (e.g., king size, queen size, super single size, etc.); and a sealing band 14 that seals the edge of the mattress body 11.

[0038] The mattress body 11 may be formed into a hexahedron by shape retention members 15 attached to four corner portions of the mattress body 11, and in this state, the sealing band 14 may seal four side surfaces of the mattress body 11.

[0039] The mattress body 11 may include an upper plate portion 11A, a lower plate portion 11B, and a plurality of ropes 11C. However, the technical feature of the present invention is to bond the sealing band 14 to the edge of the mattress body 11 constituting the air mattress 10, and to achieve this technical feature, the mattress body 11 may be composed only of the upper plate portion 11A and the lower plate portion 11B, without including the plurality of ropes 11C.

[0040] That is, when not having the plurality of ropes 11C, in a state where the upper plate portion 11A and the lower plate portion 11B overlap, the edges of the upper plate portion 11A and the lower plate portion 11B are sealed with the sealing band 14, and then the shape retention members 15 are attached to four corner portions of the mattress body 11, thereby manufacturing the air mattress 10, and the air mattress 10 manufactured in this way can obtain a buffering force only by the pressure of the air filled inside.

[0041] In addition, even when having the plurality of ropes 11C, in a case where the upper plate portion 11A and the lower plate portion 11B overlap, the edges of the upper plate portion 11A and the lower plate portion 11B are sealed with the sealing band 14, and then the shape retention members 15 are attached to four corner portions of the mattress body 11, thereby manufacturing the air mattress 10, and the air mattress 10 manufactured in this way can have a stronger buffering force through the pressure of the air filled inside and the elasticity of the plurality of ropes 11C.

[0042] The upper plate portion 11A may be formed into a rectangle, and the lower plate portion 11B may be formed into a rectangle having the same size as the upper plate portion 11A.

[0043] After the upper plate portion 11A and the lower plate portion 11B are cut to match the size of the inflatable mattress 10 (e.g., king size, queen size, super single size, etc.) and overlap with each other in the vertical direction, the edges of the mattress body 11 are sealed with the sealing tape 14, thereby forming the basic shape of the inflatable mattress 10.

[0044] Thus, after forming the basic shape of the inflatable mattress 10, the shape retention member 15 can be adhered to the four corner portions of the mattress body 11 from the upper surface of the upper plate portion 11A to the lower surface of the lower plate portion 11B, so that the mattress body 11 has a 3D hexahedron shape, and an inflation valve 16 can be installed on one side surface to complete the inflatable mattress 10.
