It is preferable to use cotton made of synthetic fibers for the cotton (33), but natural cotton may also be used.

[0024] And a portion of the above-mentioned side (23) forms a longitudinally cut line, and a zipper (100) is installed in the cut line.

[0025] As shown in FIG. 2, when the zipper (100) is opened, the deformable skin (35) is exposed, and when a user sits on it, the main body of the quilted beanbag (10) expands due to the deformable skin (35).

[0026] And a horizontal cut is made in the above-mentioned deformed skin (35), and another zipper (109) is installed in the cut area so that the opening is exposed.

[0027] A filling material inlet (40), which will be described later, is connected to the above-mentioned opening so that the filling material (110) can be easily inserted or withdrawn.

[0028] And a Teflon coating layer (not shown) is formed on the surface of the above filler (110).

[0029] FIG. 3 is a manufacturing process diagram of the quilted beanbag (10) according to the present invention.

[0030] As shown in the drawing, in order to manufacture the quilted beanbag (10), the top surface (21), the side surface (23), the bottom surface (24), the filler inlet (40), and the filler (110) are prepared through the top surface manufacturing step (S10), the side surface preparation step (S20), the bottom surface preparation step (S30), the inlet preparation step (S40), and the filler preparation step (S50).

[0031] The above upper surface preparation step (S10) proceeds with a cotton winding roll preparation step (S110) in which a cotton winding roll (not shown) is prepared with cotton (33) wound to a certain thickness, a mesh winding roll preparation step (S120) in which a mesh (34) in the shape of a net is prepared with a mesh winding roll (not shown), and an inner lining formation step (S130) in which the mesh (34) drawn from the mesh winding roll and the cotton (33) drawn from the cotton winding roll of a certain thickness are overlapped and quilted in a certain pattern to form an inner lining (32).

[0032] The inner lining (32) formed in the inner lining formation step (S130) may be prepared by winding it onto an inner lining winding roll (not shown), or it may proceed directly to the inner lining cutting step (S11) described later.

[0033] Then, a skin roll preparation step (S140) is performed to prepare a skin winding roll (not shown) on which the skin (31) consisting of a single layer is wound.

[0034] After that, an inner skin cutting step (S11) is performed in which the inner skin (32), which is bonded with cotton (33) and mesh (34), is cut into a circular shape while continuously drawing out the inner skin (32) from the inner skin winding roll, and an outer skin cutting step (S12) is performed in which the outer skin (31) is continuously drawn out from the outer skin winding roll and cut into a circular shape.

[0035] In this way, the inner skin (32), which was cut into a circle in the inner skin cutting step (S11), is attached to the upper surface of the ring-shaped fastening member (50) with the mesh (34) positioned downwards, and the outer skin fastening step (S14), which was cut into a circle in the outer skin cutting step (S12), is attached to the ring-shaped fastening member (50) with the outer skin (31) positioned on the upper surface of the attached inner skin (32), are sequentially carried out.

[0036] The above-mentioned fastening member (50) is explained with reference to FIG. 4.

[0037] As illustrated in the drawing, the fastening member (50) according to the present invention comprises a ring-shaped base plate (51) with the center portion removed from the original plate, a hook surface (52) on which a hook for a Velcro tape is formed and which is mounted on the upper surface of the base plate (51), an arc-shaped plate (54), and a clamp (53) equipped with a handle (55).

[0038] And when the arc plates (54) of the clamps (53) are connected in multiple numbers, they form the same shape as the base plate (51). That is, the outer shell (31) and the inner shell (32), which are stacked by the multiple clamps (53), are firmly attached to the hook surface (52) fixed to the base plate (51).

[0039] In this way, when the circular outer shell (31) and inner shell (32) are attached to the fastening member (50) by means of a plurality of clamps (53), radial quilting is easily achieved using the fastening member (50) to which the outer shell (31) and inner shell (32) are attached.

[0040] A radial quilting step (S15) is performed in which radial quilting (25) is performed on the inner skin (32) and the outer skin (31) which are attached to and laminated on the above-mentioned fastening member (50).

[0041] In the above radial quilting step (S15), quilting is performed by a quilting machine or by hand quilting, and the center of the outer shell (31) forming a circular shape becomes the center of point symmetry, so that radial quilting (25) is performed by quilting in a point-symmetric shape.

[0042] In addition, in the above radial quilting step (S15), the fastening band (50) may be fixed and the quilting machine (not shown) may move while quilting is performed, but it is preferable that the quilting machine be fixed and the fastening band (50) move while quilting is performed.

[0043] After the above radial quilting step (S15), an upper surface forming step (S16) is performed to complete the upper surface (21) by connecting the edges of the outer skin (31) and the inner skin (32) by sewing.

[0044] The above side preparation step (S20) proceeds with a side inner lining cutting step (S21) in which the inner lining (32), in which cotton (33) and mesh (34) are bonded in the above inner lining formation step (S130), is cut into a rectangular shape, and a side outer lining cutting step (S22) in which the outer lining (31) prepared in the above outer lining roll preparation step (S140) is drawn out from the outer lining winding roll and cut into a rectangular shape.

[0045] Then, a side forming step (S23) is performed in which the edges of the rectangular inner lining (32) cut in the side inner lining cutting step (S21) and the rectangular outer lining (31) cut in the side outer lining cutting step (S22) are connected by sewing to form a side.

[0046] A cut line forming step (S24) is performed in which a portion of the side formed in the above side forming step (S23) is cut in the longitudinal direction to form a cut line, a zipper attachment step (S25) is performed in which a zipper (100) is attached to the cut line, and a deformed skin attachment step (S26) is performed in which the deformed skin (35) exposed when the zipper (100) attached in the above zipper attachment step (S25) is opened is connected by sewing.

[0047] And the lower surface preparation step (S30) is composed of a lower surface inner surface cutting step (S31) in which the inner surface (32), in which cotton (33) and mesh (34) are joined in the inner surface formation step (S130), is cut into a circular shape, and a lower surface outer surface cutting step (S32) in which the outer surface (31) prepared in the outer surface roll preparation step (S140) is drawn out from the outer surface winding roll and cut into a circular shape, and a lower surface formation step (S33) in which the inner surface (32) cut in the lower surface inner surface cutting step (S31) is positioned so that the mesh (34) is positioned at the bottom, and the outer surface (31) cut in the lower surface outer surface cutting step (S32) is positioned on the upper surface of the inner surface (32) by connecting the edges with sewing to form the lower surface (24).

[0048] In addition, the filler inlet (40) in the above-mentioned inlet preparation step (S40) is explained with reference to FIG. 5.

[0049] As illustrated in the drawing, the filler inlet (40) is composed of a connecting pipe (41) having a hollow portion formed therein and one end connected to the main body, a sealing zipper (43) mounted on the other end of the connecting pipe (41), and zipper teeth (42) arranged in a row formed on the outer surface of the connecting pipe (41).

[0050] The above-mentioned filler inlet (40) is connected to the filler storage container (60) so that the filler (110) stored in the filler storage container (60) can be easily filled into the interior of the main body.

[0051] The filling material storage container (60) illustrated in the drawing is equipped with a sealing zipper (62) to prevent leakage of the contained filling material (110), and is also provided with a zipper tooth portion (61) and a connecting zipper slider (63).

[0052] The above connecting zipper slider (63) is a slider that connects and separates the zipper tooth part (42) mounted on the connecting tube (41) and the zipper tooth part (61) mounted on the filling material storage container (60). In the drawing, reference numeral 45 is a sealing zipper slider attached to the connecting tube, and reference numeral 63 is a sealing zipper slider mounted on the filling material storage container (60).

[0053] Filling and discharge of the filling material (110) are easily achieved through the filling material inlet (40) configured as described above.

[0054] The above filler preparation step (S50) proceeds to a filler foaming step (S51) in which a foaming agent is impregnated into a polystyrene (PS) resin to foam it, a filler molding step (S52) in which the EPS foamed in the filler foaming step (S51) is molded into a ball shape, and a filler coating step (S53) in which PTFE (Poly Tetra Fluoro Ethylene) is sprayed onto the outer surface of the filler molded in the filler molding step (S52) to form a Teflon coating layer to complete the filler.

[0055] In the above filler coating step (S53), the Teflon coating layer is formed by spraying a room-temperature curing Teflon coating agent.

[0056] The Teflon coating layer formed in this way maintains heat resistance and can be used normally from -260°C to 260°C. It also maintains a low coefficient of friction, which is typically 0.5 to 0.20.

[0057] Therefore, the filling material (110) on which the Teflon coating layer is formed increases fluidity within the main body, so the shape of the beanbag (10) can be easily deformed, and also has the effect of increasing durability.

[0058] The above description is merely one embodiment for implementing the quilted beanbag and the method for manufacturing the same according to the present invention. The present invention is not limited to the above-described embodiment, and the technical concept of the present invention extends to the scope in which various modifications can be made by anyone with ordinary knowledge in the field to which the invention belongs, without departing from the essence of the invention as claimed in the following claims.
