により隅部の補強が行われる。A watertight sheet such as a synthetic resin sheet or a rubberized sheet is used for the bag body of the water bed. conventionally,
A single watertight sheet cut into a predetermined shape is bent back and forth and left and right, the left and right folding ends and the front and back folding ends are butted against each other, and the butted ends are welded and sealed to each other to form a flat mattress-like sheet. It is generally processed into a rectangular parallelepiped. Sixth
The figure shows the structure of a conventional water bed bag. As shown in FIG. 7, the bag body 21 shown in FIG. 6 has a notch 22 provided at a key portion and is cut into a predetermined shape. A side view and a bottom part are formed, and further, the edges of each part are folded back to the front side and the back side, and the folded ends are butted and welded. The place to be welded and sealed is shown in FIG. and both edges junction w 1 of the sheet butted at the bottom center, as shown in, the rectangular front and back, joints w of both folded edges butted from each top side and bottom side folded at a right angle 2 and a joining portion w 3 between the rising both side edges of the folded end and the side surface end edge. Then, with respect to the joint portion w 3 between the front surface or the back surface and the side surface which is the corner portion of the bag body, the cloth 24 is applied to the outer surface as shown in FIG. 8, and the cloth is spread over the surface (back surface) and the side surface. The corners are reinforced by bonding 24.
ウォータベッドの袋体21は、第９図に示すように有底箱

また、接合部が直接目に触れる面に形成されることは外
観上も見苦しい。By the way, the bag body 21 of the water bed deteriorates due to material fatigue of the welded joint over a long period of use, cracks occur in the welded portion of the sheet surface, this grows, and finally the sheet is cut. There is a problem that water leakage occurs. Material fatigue is caused by a force repeatedly applied from the outside, such as bending, stretching, and vibration of the seat surface. When the joints are formed on the rising surfaces of the front surface and the back surface of the bag body 21, structurally, an external force is applied. It has a drawback that it is easily affected, and therefore cutting due to material fatigue is likely to occur.
In addition, it is unsightly in appearance that the joint is formed on the surface that is directly visible.

に開口した口栓である。FIG. 2 is a plan view of the upper sheet used in the present invention. The upper sheet 1 secures the length of the rising portion of the bag body at both corners of each side, notches both corners of each side at a right angle, and further secures the width of the bottom edge folded portion at its outer edge. It is a rectangular sheet having notches 2 cut out in an inclined shape at four corners. The seat surface is divided into an upper surface portion 3, a four-circumferential rising portion 4, and a bottom edge portion 5, and as shown in FIG. 3, the sheet surface of the upper sheet 1 forms an edge of the upper surface portion 3. Bend at a right angle with a folding curve,
Further, the bottom edge portion 5 attached to the rising portion 4 is folded back inward at a right angle, and the end edge and the bottom edge portion 5 of the rising portions 4 adjacent to each other are folded.
The edges of the bag are welded and joined to each other to form a hollow rectangular parallelepiped having an opening 6 on the bottom surface to be the main body of the bag body 7, as shown in FIG. A cloth 8 is applied to each rising portion 4 across the front surface or the back surface and the side surface of the rectangular parallelepiped, and the cloth 8 is welded to the sheet surface of the bag body 7 to increase the sealing strength of the joint portion. Lower sheet 9
Is a rectangular sheet that seals the bottom opening of the bag 7. The lower sheet 9 is applied to the opening 6 in the bottom edge portion 5 folded back on the lower surface of the rectangular parallelepiped formed by the shaping of the upper sheet 1, and is welded and joined to the mouth edge thereof to seal the bag body 7. The bag body 7 shown in FIG. 1 is completed. Reference numeral 10 in the figure denotes a spout that is opened in the upper surface sheet of the bag body 7.
本発明による袋体７は、口栓10を通して中空内部に水が
充填され、第５図に示すようにフレーム11内に設置して
ウォータベッドとして使用される。The bag body 7 according to the present invention is filled with water through the spout 10 and is installed in the frame 11 as shown in FIG. 5 to be used as a water bed.

It is possible to avoid cracking and cutting from the welded joint 12 with little influence of material fatigue such as bending, stretching, and vibration occurring in the bag body. In addition, the joint part 12 of both sheets is a frame
It is hidden by the lower surface of the bag body 7 which is in contact with the bottom of 11 and is not exposed on the outer surface.

Therefore, the upper and lower sheets are joined to each other on the lower surface of the rectangular parallelepiped that is in contact with the floor of the frame, so that the welded joint between the upper sheet and the lower sheet can be comfortably attached during use of the water bed. It is possible to prevent the generation of cracks that lead to cutting in the meantime and to significantly improve the durability. In addition, since the joint between both sheets is not exposed on the outer surface during use of the water bed, it is excellent in appearance.Furthermore, the rising parts of the four corners can be welded while the bag is open, so the welding workability is improved. And the effect of being able to easily attach the cloth.

ータベッド用袋体の製造方法。2. A method of manufacturing a water bed, comprising a step of processing an upper sheet and a step of welding upper and lower sheets, wherein the bag body of the water bed is processed into a hollow rectangular parallelepiped by combining the upper and lower sheets. Is a sheet to be processed into a hollow rectangular parallelepiped with a part of the bottom surface opened, with notches at the four corners, and the sheet surface is
The lower sheet is a rectangular sheet that seals the lower opening of a hollow rectangular parallelepiped, and is divided into an upper surface portion, rising portions on each side of the four circumferences, and a bottom edge portion attached to the rising portions on each side. In the sheet processing step, the upper sheet is bent at a right angle in the same direction at the edge of the upper surface to form rising portions on each side of the four circumferences, and further, each bottom edge portion attached to each rising portion is folded back at a right angle to the inside,
After welding the edges of the rising parts and the bottom edges that are adjacent to each other by welding and molding them into a hollow rectangular parallelepiped having an opening surrounded by the bottom edges of each side on the lower surface, the space between the edges of the rising parts This is a process of covering the welded joint part of the above and welding the cloth to the sheet surface across the rising parts of adjacent sides.The upper and lower sheet welding process is the opening edge of the lower surface of the rectangular parallelepiped formed by the upper sheet processing process. A method for manufacturing a waterbed bag body, which is a step of welding the lower sheet to the first sheet, and forming the lower surface of the rectangular parallelepiped with the lower sheet and the bottom edge portion of the upper sheet surrounding the four circumferences.
