Description

Quilted bean bag and manufacturing method thereof {QUILTED BEAN BAG AND MANUFACTURING METHOD THEREOF}

The present invention relates to a quilted beanbag, and more particularly, to a quilted beanbag having quilting formed on the upper surface of the beanbag, the shape of which can be easily changed, and in particular, increased durability.

In general, a bean bag is an item that does not use a frame to form the outer shape, but rather fills the inside of the outer shell with filling material, so that it can be transformed in various ways according to the user's posture, allowing the user to rest comfortably.

In the case of existing bean bags, spherical filling materials are placed within an outer shell made of flexible fabric or vinyl material, occupying approximately 60% to 80% of the total space to form a cushion.

When a user uses a bean bag, the filling materials contained within the outer shell are distributed throughout the entire space inside the main body due to the user's body weight.

As shown in the enlarged view of the main body of Fig. 2, the upper surface (21), the side surface (23), and the lower surface (24) are composed of an inner skin (32) and an outer skin (31), and the inner skin (32) is composed of cotton (33) and a mesh (34). It is preferable to use cotton made of synthetic fibers as the cotton (33), but natural cotton may also be used.

And a part of the above side (23) forms a longitudinal cut line, and a zipper (100) is mounted on the cut line.

As shown in Fig. 2, when the zipper (100) is opened, the deformation skin (35) is exposed, and when the user sits down, the main body of the quilted bean bag (10) expands by the deformation skin (35).

And, a horizontal cut is made in the above-mentioned deformation skin (35), and another zipper (109) is mounted on the cut portion to expose the opening.

The above opening is connected to a filler injection port (40) described later, so that the filler (110) can be easily injected or extracted.

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

Figure 3 is a manufacturing process diagram of the above-mentioned quilted bean bag (10) according to the present invention.

As shown in the drawing, in order to manufacture the above-mentioned quilted bean bag (10), the upper surface (21), the side surface (23), the lower surface (24), the filler injection port (40), and the filler (110) are prepared through the upper surface manufacturing step (S10), the side preparation step (S20), the lower surface preparation step (S30), the inlet preparation step (S40), and the filler preparation step (S50).

The above-mentioned surface preparation step (S10) includes a cotton winding roll preparation step (S110) for preparing a cotton winding roll (not shown) on which cotton (33) is wound with a certain thickness, a mesh winding roll preparation step (S120) for preparing a mesh winding roll (not shown) on which a mesh (34) in the shape of a mesh is wound, and an inner skin formation step (S130) for forming an inner skin (32) by overlapping the mesh (34) drawn from the mesh winding roll and the cotton (33) of a certain thickness drawn from the cotton winding roll and joining them in a certain pattern.

The endothelium (32) formed in the above endothelium formation step (S130) may be prepared by being wound on an endothelium winding roll (not shown), or may proceed directly to the endothelium cutting step (S11) described later.

And, a skin roll preparation step (S140) is performed to prepare a skin roll (not shown) on which the skin (31) composed of a single layer is wound.

After that, an inner skin cutting step (S11) is performed in which the inner skin (32) is continuously withdrawn from the inner skin take-up roll and the inner skin (32) to which the cotton (33) and the mesh (34) are joined is cut into a circular shape, and an outer skin cutting step (S12) is performed in which the outer skin (31) is continuously withdrawn from the outer skin take-up roll and cut into a circular shape.

In this way, the inner skin (32) cut into a circle in the inner skin cutting step (S11) is sequentially performed through the inner skin bonding step (S13) of bonding the inner skin (32) to the upper surface of the ring-shaped bonding band (50) with the mesh (34) positioned downward, and the outer skin bonding step (S14) of bonding the outer skin (31) cut into a circle in the outer skin cutting step (S12) to the upper surface of the bonded inner skin (32) with the mesh (34) positioned downward, to the ring-shaped bonding band (50).

The above-mentioned fixing member (50) is described with reference to FIG. 4.

As shown in the drawing, the fixing member (50) according to the present invention is composed of a ring-shaped base plate (51) in which the center portion of the base plate is deleted, a hook surface (52) on which a hook of a Velcro tape is formed to be mounted on the upper surface of the base plate (51), and a clamp (53) equipped with an arc-shaped plate (54) and a handle (55).

And when the circular plates (54) of the above clamps (53) are connected in multiple ways, they form the same shape as the base plate (51). That is, the outer skin (31) and the inner skin (32) laminated by the multiple clamps (53) are firmly attached to the hook surface (52) fixed to the base plate (51).

In this way, when the circular outer skin (31) and inner skin (32) are fixed to the fixing member (50) by a plurality of the forceps (53), radial quilting is easily achieved using the fixing member (50) to which the outer skin (31) and inner skin (32) are fixed.

A radial beaming step (S15) is performed in which radial beams (25) are formed on the inner skin (32) and the outer skin (31) that are laminated and bonded to the bonding member (50).

In the above radial quilting step (S15), quilting is performed by a quilting machine or hand quilting. The center of the outer skin (31) forming a circle becomes the center of point symmetry, and the quilting is performed in a point symmetry shape to form a radial quilting (25).

In addition, in the above radial quilting step (S15), quilting can be performed while the quilting machine (not shown) is fixed and the quilting machine is moved, but it is preferable that quilting is performed while the quilting machine is fixed and the quilting machine is moved.

After the above radial beam step (S15), a top surface forming step (S16) is performed to complete the top surface (21) by sewing the edges of the outer skin (31) and the inner skin (32).

And, in the side inner skin cutting step (S21), the edges of the inner skin (32) of the rectangular model cut out and the outer skin (31) of the rectangular model cut out in the side outer skin cutting step (S22) are connected by sewing to form the side surface, in the side forming step (S23).

In the side forming step (S23), a part of the side formed is cut lengthwise to form a cut line, and a zipper attachment step (S25) of attaching a zipper (100) to the cut line is performed. When the zipper (100) attached in the zipper attachment step (S25) is opened, a deformation skin attachment step (S26) is performed in which the exposed deformation skin (35) is connected by sewing.

And the above-mentioned lower surface preparation step (S30) is composed of a lower surface inner skin cutting step (S31) in which the inner skin (32) in which the cotton (33) and the mesh (34) are joined in the inner skin formation step (S130) is cut into a circular shape, and a lower surface outer skin cutting step (S32) in which the outer skin (31) prepared in the outer skin roll preparation step (S140) is taken out from the outer skin take-up roll and cut into a circular shape, and a lower surface forming step (S33) in which the inner skin (32) in the circular shape cut in the lower surface inner skin cutting step (S31) is positioned so that the mesh (34) is positioned downward, and the outer skin (31) in the circular shape cut in the lower surface outer skin cutting step (S32) is positioned so that the edges are sewn to form the lower surface (24) on the upper surface of the inner skin (32).

In addition, in the above-mentioned injection port preparation step (S40), the filling material injection port (40) is described with reference to FIG. 5.

As shown in the drawing, the filling material inlet (40) is formed with a hollow portion and is composed of a connecting tube (41) that is connected to the main body at one end, a sealing zipper (43) mounted on the other end of the connecting tube (41), and zipper teeth (42) that are aligned in a row formed on the outer surface of the connecting tube (41).

The above-mentioned filler injection port (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.

The filling storage container (60) shown in the drawing is equipped with a sealing zipper (62) that prevents the contained filling material (110) from leaking, and is also provided with one zipper tooth portion (61) and a connecting zipper slider (63).

The above connecting zipper slider (63) is a slider that connects and separates the zipper teeth (42) mounted on the connecting pipe (41) and the zipper teeth (61) mounted on the filling storage container (60). In the drawing, reference numeral 45 is a sealing zipper slider attached to the connecting pipe, and reference numeral 63 is a sealing zipper slider mounted on the filling storage container (60).

The filling and discharge of the filler (110) is easily accomplished by the filler inlet (40) configured as described above.

The above-mentioned filler preparation step (S50) is performed by a filler foaming step (S51) of impregnating a foaming agent into a polystyrene (PS) resin to foam it, a filler molding step (S52) of molding the EPS foamed in the filler foaming step (S51) into a ball shape, and a filler coating step (S53) of forming a Teflon coating layer by spraying PTFE (Poly Tetra Fluoro Ethylene) on the outer surface of the filler molded in the filler molding step (S52) to complete the filler.

In the above filling coating step (S53), the Teflon coating layer is formed by spraying a room temperature curing Teflon coating agent.

The Teflon coating layer formed in this way maintains heat resistance and can be used normally from -260℃ to 260℃. In addition, it maintains a low coefficient of friction, which is usually 0.5 to 0.20.

Accordingly, the filler (110) on which the Teflon coating layer is formed increases fluidity within the main body, so that the shape of the bean bag (10) can be easily deformed, and durability is also increased.

The above description is only one embodiment for carrying out the quilted bean bag and the manufacturing method thereof according to the present invention, and the present invention is not limited to the above-described embodiment, and as claimed in the following claims, it will be understood that the technical idea of the present invention encompasses a range in which various modifications can be made by anyone having ordinary skill in the art to which the present invention pertains without departing from the gist of the present invention.
