[0007] [Figure 1] It is a diagram for explaining a mannequin doll. [Figure 2] It is a diagram for explaining a mannequin doll. [Figure 3] This is a close-up view of the main parts of a mannequin. [Figure 4] This is a diagram illustrating the molding die. [Figure 5] This is a diagram illustrating the molding of the first layer. [Figure 6] This diagram illustrates the molding of the third layer. [Figure 7] This diagram illustrates the molding of the second layer. [Figure 8] This is a diagram illustrating the joining of molds. [Figure 9] This is a diagram illustrating the joining of connectors. [Figure 10] This diagram illustrates the separation of the mold and the connector. [Figure 11] This diagram illustrates the molding process for the fourth through sixth layers.

[0008] The embodiments will be described below. In the embodiments, a paper mannequin doll 1 made of a material containing mulberry fibers will be used as an example. Figure 1 is a diagram illustrating mannequin 1. Figure 2 is a diagram illustrating mannequin 1. Figure 2 is a schematic diagram of a cross-section obtained by cutting mannequin 1 in Figure 1 along plane A. Figure 3 is a magnified view of the main part of mannequin 1. Figure 3(a) is a magnified view of area A in Figure 2. Figure 3(b) is a magnified view of area B in Figure 2. In Figures 3(a) and (b), the thickness of each layer is exaggerated.

[0009] Here, "vertical direction" in the drawing refers to the height direction of mannequin 1. Therefore, when "upper side" is written, it refers to the "head side" of mannequin 1, and when "lower side" is written, it refers to the "leg side" of mannequin 1. Furthermore, "front-to-back direction" refers to the front-to-back direction of mannequin 1. Therefore, when "front side" is written, it refers to the "front side" of mannequin 1, and when "back side" is written, it refers to the "back side" of mannequin 1. Further, the "left - right direction" means the left - right direction of the mannequin 1. Therefore, when expressed as the "right side", it means the "right - hand side" of the mannequin 1, and when expressed as the "left side", it means the "left - hand side" of the mannequin 1.

[0010] As shown in FIG. 1, the mannequin 1 is provided in a direction along a straight line Lz along the vertical direction. The mannequin 1 has a torso part 2, arm parts 3, 3 connected to the right side and the left side of the torso part 2, hand parts 4, 4 respectively connected to the arm parts 3, and a leg part 5 connected to the lower part of the torso part 2. Also, a head part (not shown) is connected to the upper part of the torso part 2.

[0011] As shown in FIG. 2, in a cross - sectional view in a direction orthogonal to the vertical direction, the torso part 2 and the arm part 3 of the mannequin 1 are each a cylindrical part having hollow parts Ra, Rb. Although the description is omitted, the hand part 4 and the leg part 5 (see FIG. 1) are also cylindrical parts having hollow parts.

[0012] The torso part 2 is composed of a semi - cylindrical front part 21 covering the front side of the hollow part Ra and a back part 22 covering the back side. The torso part 2 is formed by arranging the inner peripheral surface 21b of the front part 21 and the inner peripheral surface 22b of the back part 22 to face each other in the front - back direction and joining the mating surfaces 21a, 22a of each other in the front - back direction.

[0013] The arm part 3 is composed of a semi - cylindrical front part 31 covering the front side of the hollow part Rb and a back part 32 covering the back side. The arm part 3 is formed by arranging the inner peripheral surface 31b of the front part 31 and the inner peripheral surface 32b of the back part 32 to face each other in the front - back direction and joining the mating surfaces 31a, 32a of each other in the front - back direction.

[0014] As shown in (a) of FIG. 3, in the front part 21 of the torso part 2, six layers are laminated. Specifically, from the inner peripheral surface 21b side (upper side in the figure) to the outer peripheral surface 21c side (lower side in the figure) of the front part 21, a linen layer 212 (second layer), an adhesive layer 213 (third layer), a paper layer 211 (first layer), a base layer 214 (fourth layer), a build-up layer 215 (fifth layer), and a coating layer 216 (sixth layer) are laminated in this order.

[0015] As shown in (b) of FIG. 3, the back part 22 of the body part 2 also has six layers laminated in the same manner as the front part 21. Specifically, from the inner peripheral surface 22b side (lower side in the figure) to the outer peripheral surface 22c side (upper side in the figure) of the back part 22, a linen layer 222 (second layer), an adhesive layer 223 (third layer), a paper layer 221 (first layer), a base layer 224 (fourth layer), a build-up layer 225 (fifth layer), and a coating layer 226 (sixth layer) are laminated in this order.

[0016] In the front part 21 and the back part 22, the linen layers 212 and 222, the adhesive layers 213 and 223, the paper layers 211 and 221, the base layers 214 and 224, the build-up layers 215 and 225, and the coating layers 216 and 226 are each made of the same material. Although the description is omitted, the arm part 3, the hand part 4, and the leg part 5 also have a multilayer structure made of the same material as the body part 2.

[0017] Each part of the mannequin 1 is manufactured by hand lay-up molding in which a material is bonded to a female molding die. In the following description, the case of molding the front part 21 of the body part 2 will be taken as an example for explanation.

[0018] (Molding die 8) FIG. 4 is a diagram for explaining the molding die 8 for the front part 21 of the body part 2. (a) of FIG. 4 is a front view of the molding die 8. (b) of FIG. 4 is a schematic diagram of the A-A cross section of (a) of FIG. 4.

[0019] As shown in (a) of FIG. 4, the molding die 8 has a base part 80 provided with a recess 85 corresponding to the shape of the front part 21 (see FIG. 2) of the body part 2, and five flange parts 81 (81A to 81E) along the periphery of the recess 85.

[0020] As shown in Figure 4(b), in a cross-sectional view along the left-right direction, the recess 85 is recessed towards the front as it approaches the center of the body portion 2 in the left-right direction. The base portion 80 is curved to conform to the shape of the recess 85.

[0021] As shown in Figure 4(a), in a front view, the flange portions 81A and 81B are provided on one side and the other side of a straight line Lz that runs in the vertical direction, oriented along the line Lz. Multiple bolt holes Ba pass through each of the flange portions 81A and 81B. As shown in Figure 4(b), the flange portions 81A and 81B are connected to the rear end of the base portion 80.

[0022] As shown in Figure 4(a), flange portions 81C and 81D are provided above flange portions 81A and 81B. Flange portions 81C and 81D are provided on one side and the other side of the straight line Lz, and are oriented in a direction that intersects the straight line Lz. Multiple bolt holes Ba pass through each flange portion 81C and 81D. Although not shown in the figure, flange portions 81C and 81D are also connected to the rear end of the base portion 80, similar to flange portions 81A and 81B.

[0023] As shown in Figure 4(a), the flange portion 81E is positioned to intersect the straight line Lz and connects the lower ends of flange portions 81A and 81B. Multiple bolt holes Ba pass through the flange portion 81E. The flange portion 81E protrudes forward (towards the back of the paper in the figure) from the base portion 80 (see Figure 9(a)).

[0024] A notch 82 communicating with the recess 85 is provided between flange portions 81A and 81C. A notch 83 communicating with the recess 85 is provided between flange portions 81B and 81D. A notch 84 communicating with the recess 85 is provided between flange portions 81C and 81D.

[0025] Figure 5 illustrates the molding of the first layer, the paper layer 211. Figure 5(a) shows the process of laminating the paper material 211a to the mold 8. Figure 5(b) is a schematic diagram of the AA cross-section in Figure 5(a). In Figure 5(a), cross-hatching is applied to the area in the mold 8 where the paper material 211a is bonded.

[0026] As shown in Figure 5(a), first, a release agent (for example, silicone spray) is applied to the recess 85 and notches 82-84 of the mold 8, and then the paper material 211a containing mulberry fibers and pulp fibers is bonded to it.

[0027] The paper material 211a is formed by filtering a liquid mixture of mulberry fiber powder and pulp fiber powder. The liquid can be, for example, water mixed with a viscous agent (pasteurizer).

[0028] Here, the inventors of the present application have found through diligent study that the rigid strength of the paper material 211a can be improved by setting the mixing ratio of mulberry fibers to pulp fibers to a mass ratio in the range of 1:1 to 1:3. The paper material 211a according to this embodiment is composed of mulberry fibers and pulp fibers blended in a mass ratio of 1:2.

[0029] The paper material 211a may have a basic shape that is substantially rectangular when viewed from the front. In this case, it is preferable to bond the paper material 211a so that a part of it extends to the flange portions 81A to 81E of the mold 8. Furthermore, from the viewpoint of improving rigidity and strength, it is preferable to bond adjacent paper materials 211a so that a part of them overlaps with each other.

[0030] As a result, as shown in Figure 5(b), when the paper material 211a bonded to the mold 8 dries, a layer of paper 211 is formed that overlaps the recess 85 of the mold 8.

[0031] Here, as the paper material 211a dries, the shape of the paper layer 211 may deform (for example, shrink). Therefore, as shown in Figure 5(b), it is preferable to fix the flange portion 81 (81A~81E) and the portion 211a' of the paper material 211a that overlaps with the flange portion 81 (81A~81E) using a jig J (see dashed line in the figure), such as a hand clamp, before the paper material 211a dries. This reduces deformation of the paper layer 211 even after the paper material 211a dries, and maintains a shape that conforms to the recess 85.

[0032] Figure 6 illustrates the molding of the third layer, the adhesive layer 213. Figure 6(a) shows the mold 8 to which the adhesive 213a has been applied. Figure 6(b) is a schematic diagram of the AA cross-section of Figure 6(a). In Figure 6(a), cross-hatching with different pitches is applied to the area of ​​the mold 8 where adhesive 213a is applied and the area where the paper material 211a is bonded.

[0033] In this embodiment, as shown in Figure 6(a), adhesive 213a is applied on top of the dry paper layer 211. Specifically, adhesive 213a is applied to the entire surface of the area avoiding the portion 211a' that overlaps with the flange portion 81 (81A~81E) of the mold 8. As a result, a layer of adhesive 213 is formed on top of the paper layer 211, as shown in Figure 6(b).

[0034] In this embodiment, adhesive 213a is a vinyl acetate-based adhesive. Vinyl acetate adhesives are emulsions in which vinyl acetate monomer is dispersed in water, resulting in low emissions of volatile organic compounds (VOCs) and minimizing the burden on the environment and human health. Furthermore, vinyl acetate adhesives dry quickly and become stronger once dry, making them particularly suitable for porous materials such as wood, paper, and fabric.

[0035] When adhesive 213a is applied to the paper layer 211, the surface of the paper layer 211 becomes moist due to the moisture contained in adhesive 213a, improving adhesion with the hemp cloth 212a (see Figure 7(a)). By impregnating the hemp cloth 212a with adhesive 213a, the mulberry fibers of the paper layer 211 and the fibers of the hemp cloth 212a mix at the interface, improving the rigidity and strength of the paper layer 211.

[0036] Figure 7 illustrates the molding of the second layer, the linen layer 212. Figure 7(a) shows the process of bonding the linen 212a to the mold 8. Figure 7(b) is a schematic diagram of the AA cross-section in Figure 7(a).

[0037] As shown in Figure 7(a), the linen fabric 212a is then bonded to the undried adhesive layer 213. For example, 100% linen fabric can be used for the linen fabric 212a.

[0038] The burlap 212a may have a basic shape that is approximately rectangular in front view. In this case, it is preferable to bond the burlap 212a so that it does not overlap the flange portions 81A to 81E of the mold 8. Furthermore, from the viewpoint of improving rigidity, it is preferable to bond adjacent burlap 212a so that a portion of them overlaps with each other.

[0039] As shown in Figure 7(b), the adhesive layer 213 dries due to the evaporation of moisture, forming a layer of linen fabric 212 that overlaps the adhesive layer 213. As a result, using the mold 8, the paper layer 211, the linen layer 212, and the adhesive layer 213 interposed between the paper layer 211 and the linen layer 212 are formed, which are among the six layers that make up the front portion 21. The paper layer 211 and the linen layer 212 are firmly bonded together via the adhesive layer 213.

[0040] Although not shown in the diagram, after layering the burlap 212a on top of the adhesive layer 213, another layer of adhesive 213a may be applied to the burlap 212a. When adhesive 213a is applied to linen fabric 212a in layers, the adhesive 213a can be impregnated into the gaps between the fibers of linen fabric 212a during the application process.

[0041] When the adhesive 213a is applied to the paper layer 211, some of the moisture in the adhesive 213a is absorbed by the paper layer 211. As a result, when the adhesive 213a is dried, the paper layer 211 becomes prone to deformation again. Therefore, as shown in Figure 7(b), it is preferable to fix the flange portion 81 (81A~81E) and the portion 211a' of the paper material 211a that overlaps with the flange portion 81 (81A~81E) with a jig J such as a hand clamp (see dashed line in the figure) even when drying the adhesive 213a. This reduces the shrinkage and deformation of the paper layer 211 as the adhesive 213a dries, and allows it to maintain its shape along the recess 85.

[0042] Figure 8 illustrates the joining of molds 8 and 9. Figures 8(a) and 8(b) illustrate the molds 8 and 9 before joining, respectively. Figure 8(c) illustrates the joining of the molds 8 and 9 and corresponds to the AA cross-section in Figure 8(a). In Figures 8(a) and 8(b), different types of hatching are applied to the flange portions 81 and 91 of the molds 8 and 9 and the adhesive G to make the positional relationship easier to understand.

[0043] As shown in Figures 8(a) and 8(c), in the mold 8, after the adhesive layer 213 (see Figure 7) hardens, the portion 211a' (see Figure 7) of the paper layer 211 that overlaps with the flange portions 81A to 81E is cut off. In addition, the edges of the paper layer 211, the adhesive layer 213, and the linen layer 212 are trimmed so that they are substantially flush with the flange portions 81 (81A to 81E), thereby forming the mating surface 21a of the front portion 21.

[0044] Furthermore, as shown in Figure 8(c), adhesive G is applied to the mating surface 21a of the front portion 21. As shown in Figure 8(a), adhesive G is applied linearly along the inner periphery of the flange portions 81A to 81D (areas with cross-hatching in the figure).

[0045] Here, adhesive G is a mixture of hemp fibers and the vinyl acetate-based adhesive 213a described above. By mixing hemp fibers, which are high-strength fibers, with adhesive 213a, the viscosity (strength) of adhesive G is increased. As a result, even if adhesive G is applied thickly to the mating surface 21a of the front part 21 and the mating surface 22a of the back part 22 (described later), it is less likely to drip, and the front part 21 and the back part 22 can be firmly fixed together. Furthermore, the mixing ratio of adhesive 213a to hemp fibers in adhesive G is preferably in the range of 1:1 to 2:1 by mass.

[0046] Furthermore, as shown in Figure 8(c), a rod-shaped stay 6 is provided in the recess 85 of the mold 8 as a reinforcing material, traversing the recess 85 in the left-right direction. The material of the stay 6 is not particularly limited, but it is preferable to use balsa wood, which is lightweight and has high rigidity.

[0047] In this embodiment, adhesive G is also applied to one end 61 and the other end 62 of the stay 6. The stay 6 is joined to the linen layer 212 via the adhesive G. By using adhesive G containing linen fibers to join the stay 6 to the linen layer 212, the adhesive G is less likely to drip even when applied thickly, and a strong fixation can be achieved.

[0048] The stay 6 is sandwiched between the burlap layer 212 on the flange portion 81A side and the burlap layer 212 on the flange portion 81B side in the left-right direction. In this state, the rear end surface 6a of the stay 6 is positioned to protrude further back (upward in the figure) than the mating surface 21a of the front portion 21.

[0049] As shown in Figure 8(a), two stays 6 are provided, spaced apart in the vertical direction. Note that the number of stays 6 is not limited to two. There may be one, or three or more.

[0050] (Mold 9) Here, as shown in Figures 8(b) and 8(c), the back portion 22 of the torso portion 2 (see Figure 2) is formed using a female mold 9. The mold 9 has a base portion 90 with a recess 95 corresponding to the shape of the rear portion 22 of the fuselage portion 2 (see Figure 2), and five flange portions 91 (91A to 91E) along the periphery of the recess 95.

[0051] As shown in Figure 8(b), in a front view, the flange portions 91A and 91B are provided on opposite sides of a straight line Lz that runs vertically, oriented along the line Lz. Multiple bolt holes Bb pass through each of the flange portions 91A and 91B. As shown in Figure 8(c), the flange portions 91A and 91B are connected to the front end of the base portion 90.

[0052] As shown in Figure 8(b), in a front view, flange portions 91C and 91D are located above flange portions 91A and 91B. Flange portions 91C and 91D are located on opposite sides of the straight line Lz, and are positioned to intersect the straight line Lz. Multiple bolt holes Bb pass through each flange portion 91C and 91D. Although not shown in the figure, flange portions 91C and 91D are also connected to the front end of the base portion 90, similar to flange portions 91A and 91B. As shown in Figure 8(c), nuts N1 are fixed to the rear surfaces of flange portions 91A to 91D in a position that overlaps with the bolt holes Bb.

[0053] The flange portion 91E is positioned to intersect the straight line Lz and connects the lower ends of flange portions 91A and 91B. Multiple bolt holes Bb pass through the flange portion 91E. The flange portion 91E protrudes from the base portion 90 toward the rear (towards the back of the paper in the figure) (see Figure 9(a)).

[0054] A notch 92 is provided between flange portions 91A and 91C. A notch 93 is provided between flange portions 91B and 91D. A notch 94 is provided between flange portions 91C and 91D. These notches 92 to 94 are in communication with a recess 95 (see Figure 8(c)).

[0055] As shown in Figure 8(c), in the mold 9, similar to the mold 8 described above, the paper layer 221, the adhesive layer 223, and the linen layer 222 are laminated in this order in the recess 95. As a result, in the mold 9, the paper layer 221, the linen layer 222, and the adhesive layer 223 interposed between the paper layer 221 and the linen layer 222 are formed, which are among the six layers that make up the back portion 22.

[0056] Furthermore, after the adhesive layer 223 has hardened, the portion of the paper layer 221 that overlaps with the flange portions 91A to 91E (corresponding to the portion indicated by reference numeral 211a' in Figure 7) is cut off. In addition, the edges of the paper layer 221, the adhesive layer 223, and the linen layer 222 are trimmed so that they are substantially flush with the flange portions 91 (91A to 91E), thereby forming the mating surface 22a of the back portion 22.

[0057] Then, as shown in Figure 8(c), adhesive G is applied to the mating surface 22a of the back portion 22. As shown in Figure 8(b), adhesive G is applied linearly along the inner periphery of the flange portions 91A to 91D (areas with cross-hatching in the figure).

[0058] As shown in Figure 8(c), the molds 8 and 9 are joined to each other in the front-to-back direction. The molds 8 and 9 are joined together using the following procedure. (i) The flange portions 81A, 91A, 81B, 91B, 81C, 91C, and 81D, 91D are overlapped in the front-to-back direction. (ii) The bolt holes Ba of flange portion 81 (81A to 81D) and the bolt holes Bb of flange portion 91 (91A to 91D) are arranged concentrically. (iii) From the flange portion 81 (81A~81D) side, insert bolt B1 through bolt holes Ba and Bb, then screw it onto nut N1 on the flange portion 91 (91A~91D) side and tighten it (in the direction of the black arrow in the diagram).

[0059] As a result, the mating surfaces 21a, 21a of the front section 21 and the mating surfaces 22a, 22a of the back section 22 are bonded together via adhesive G, and the front section 21 and the back section 22 are fixed in place.

[0060] Furthermore, the stay 6 provided on the mold 8 side has its rear end surface 6a housed in the recess 95 of the mold 9. The rear end surface 6a of the stay 6 is sandwiched in the left-right direction between the burlap layer 222 on the flange portion 91A side and the burlap layer 222 on the flange portion 91B side. Therefore, the stay 6 is positioned so that, when viewed from the left and right directions, it overlaps with the mating surfaces 21a and 22a of the front portion 21 and the rear portion 22. This improves the rigidity around the mating surfaces 21a and 22a of the front portion 21 and the rear portion 22.

[0061] (Connector 7) As shown in Figures 8(a) and 8(b), when the molds 8 and 9 are joined together, the notches 82 and 92, 83 and 93, and 84 and 94 face each other with a gap between them in the front-to-back direction. Also, the flange portions 81E and 91E provided at the lower ends of the base portions 80 and 90 face each other with a gap between them in the front-to-back direction.

[0062] In this embodiment, four locations in the front-rear direction—between notches 82 and 92, between notches 83 and 93, between notches 84 and 94, and between flanges 81E and 91E—are sealed by connectors 7 (7T, 7L, 7R, 7B) (see Figure 10(a)). The connector 7 is installed after the adhesive G (see Figure 8) applied to the mating surfaces 21a, 22a of the front portion 21 and the back portion 22 within the molds 8 and 9, and to the stay 6 has dried.

[0063] Figure 9 illustrates the connector 7. Figure 9(a) shows the molds 8 and 9 joined together, viewed from the left. In Figure 9(a), the connector 7T that connects the head (not shown) and the connector 7L that connects the left arm 3 (see Figure 1) are shown spaced apart from the molds 8 and 9. Figure 9(b) is a schematic diagram of the connector 7L in Figure 9(a) cut along section AA. Figure 10 illustrates the separation of molds 8 and 9. Figure 10(a) illustrates the state in which all connectors 7 are attached to molds 8 and 9. Figure 10(b) illustrates the state in which molds 8 and 9 are separated.

[0064] As shown in Figure 9(a), viewed from the left, the mold 8 is provided with flange portions 820 and 840 that surround the notches 82 and 84, respectively. Multiple through holes 820a and 840a are provided in the flange portions 820 and 840. Nuts N2 (see Figure 9(b)) are fixed to the back surface of the flange portions 820 and 840 in positions that overlap with the through holes 820a and 840a.

[0065] Furthermore, the mold 9 is provided with flange portions 920 and 940 that surround the notches 92 and 94, respectively. Multiple through holes 920a and 940a are provided in the flange portions 920 and 940. Nuts N2 (see Figure 9(b)) are fixed to the back surfaces of the flange portions 920 and 940 at positions that overlap with the through holes 920a and 940a.

[0066] Although not shown in the diagram, flange portions are provided on the right side of molds 8 and 9, surrounding the notches 83 and 93, respectively. The flange portions surrounding the notches 83 and 93 have the same shape as the flange portions 820 and 920 surrounding the notches 82 and 92, so their explanation is omitted.

[0067] In this embodiment, the gap between notch 84 and notch 94 is sealed by connector 7T. The gap between notch 82 and notch 92 is sealed by connector 7L. The gap between notch 83 and notch 93 is sealed by connector 7R (see Figure 10(a)). The gap between flange portion 81E and flange portion 91E is sealed by connector 7B (see Figure 10(a)).

[0068] Here, the four connectors 7 (7T, 7L, 7R, 7B) have a basic shape consisting of a disc-shaped base 70 and a roughly cylindrical fitting portion 71 that follows the contour of each notch. In the following description, connector 7L will be used as an example to explain the configuration of each part of connector 7L and its connection to the molds 8 and 9.

[0069] As shown in Figures 9(a) and 9(b), the connector 7L has a disc-shaped base 70L and a substantially cylindrical fitting portion 71L provided on one surface 701 of the base 70L. The fitting portion 71L is positioned in the center of the base portion 70L and is fixed to the base portion 70L via two bolts B3, B3. The bolts B3, B3 are screwed into the fitting portion 71L from the other side 702 of the base portion 70L.

[0070] As shown in Figure 9(a), the base portion 70L is provided with through holes 70a at a position offset from the fitting portion 71L. Multiple through holes 70a are provided at intervals along the outer circumference of the base portion 70L. The positions of the through holes 70a correspond to the through holes 820a, 920a provided in the flange portions 820, 920 of the molds 8, 9.

[0071] As shown in Figure 9(b), an engagement hole 75 is provided in the joint surface 71a of the fitting portion 71L with the base portion 70L. As shown in Figure 9(a), the engagement hole 75 has a substantially T-shape in front view. The engagement hole 75 is provided in the region between the two bolts B3, B3.

[0072] As shown in Figure 9(b), the fitting portion 71L has an outer diameter R71 that is slightly smaller than the distance between the notches 82 and 92 in the front-rear direction. Furthermore, the adhesive G containing the aforementioned hemp fibers is applied to the entire circumference of the fitting portion 71L. The fitting portion 71L, with the adhesive G applied, is provided spanning the front portion 21 on the mold 8 side and the back portion 22 on the mold 9 side.

[0073] The connector 7L is fixed to the molds 8 and 9 by the following procedure. (i) The joining surface 71a of the fitting portion 71L is placed on one surface 701 of the base portion 70L, and then fixed with bolt B3. (ii) Apply adhesive G to the outer surface of the mating portion 71L. (iii) Insert the fitting portion 71L into the gap between the notch 82 and the notch 92 (in the direction of the white arrow in Figure 9(a)). This joins the fitting portion 71L to the front portion 21 and the back portion 22 via adhesive G. (iv) The through hole 70a of the base portion 70L is positioned concentrically with the through holes 820a and 920a of the flange portions 820 and 920. (v) From the base 70L side, pass bolt B2 through the through holes 70a and 820a and 920a, then screw it onto the nut N2 fixed to the back surface of flange portions 820 and 920, and tighten it. As a result, the connector 7L is fixed between the notches 82 and 92 in the front-rear direction (see Figure 9(a)). The connectors 7T and 7R are attached to the molds 8 and 9 using the same procedure.

[0074] Here, as shown in Figure 10(a), the connector 7B is fixed to the lower surface of the base 70B with a nut (not shown). The connector 7B is fixed by passing the bolt B2 through the flange portions 81E and 91E and screwing it into the nut on the base 70B side and tightening it. As a result, the connector 7B is fixed between flange portion 81E and flange portion 91E (see Figure 9(a)).

[0075] As shown in Figure 10(a), after fixing all the connectors 7 to the molds 8 and 9, the adhesive G between the fitting portion 71 and the front portion 21 (see Figure 9(b)) and the adhesive G between the fitting portion 71 and the back portion 22 (see Figure 9(b)) are allowed to dry.

[0076] As shown in Figures 10(a) and (b), for example, in the connector 7T, after the adhesive G has dried, the bolt B2 is loosened to detach the base 70T from the flange portions 840 and 940. Also, the bolt B3 is loosened to detach the base 70T from the fitting portion 71T.

[0077] As a result, the fitting portion 71T of the connector 7T is held in place by the body portion 2 via the adhesive G. In this state, the engagement hole 75 of the fitting portion 71T is exposed to the outside (see the enlarged area in Figure 10(b)). Similarly, with respect to the connectors 7L, 7R, and 7B, the fitting portions 71L, 71R, and 71B are held in place by the body portion 2 via adhesive G, and the engagement holes 75 are exposed to the outside.

[0078] Furthermore, the base ends of the head, arms 3, 3, and legs 5 (see Figure 1) are each provided with T-shaped engagement pins (not shown) corresponding to the engagement holes 75. The head, arms 3, 3, and legs 5 are fixed to the torso 2 by engaging the engagement pins with the engagement holes 75.

[0079] As shown in Figure 10(b), after removing all the connectors 7 from the molds 8 and 9, the molds 8 and 9 are separated in the front-to-back direction (in the direction of the white arrow in the figure), forming a body section 2 in which the front section 21, the rear section 22, and the fitting section 71 are integrated.

[0080] When the molds 8 and 9 are separated, the paper layer 211 of the front section 21 and the paper layer 221 of the back section 22 of the body section 2 are exposed to the outside (areas with cross-hatching in the figure). The adhesive layers 213 and 223 and the linen layers 212 and 222 (see Figure 8(c)) are hidden inside the body section 2.

[0081] Figure 11 is a diagram illustrating the molding process of the fourth to sixth layers in order. Figure 11(a) shows the body section 2 removed from molds 8 and 9. Figure 11(b) illustrates the molding of the fourth layer, the base layers 214 and 224. Figure 11(c) illustrates the molding of the fifth layer, the build-up layers 215 and 225. Figure 11(d) illustrates the molding of the sixth layer, the coating layers 216 and 226. Note that in Figures 11(b) to (d), each layer is partially cut out to expose the lower layer.

[0082] As shown in Figure 11(a), when the body portion 2 is removed from the molds 8 and 9, the paper layer 211 of the front portion 21 and the paper layer 221 of the back portion 22 are exposed to the outside.

[0083] As shown in Figure 11(b), the paper layers 211 and 221 are laminated with the underlay layers 214 and 224 from the outside of the body section 2 (opposite the linen layers 212 and 222), respectively.

[0084] The base layers 214 and 224 are formed by applying laundry starch 214a to the entire surface of the paper layers 211 and 221. The laundry starch 214a may contain, for example, PVA (polyvinyl alcohol).

[0085] During this process, the laundry starch 214a penetrates between the mulberry fibers and pulp fibers that make up the paper layers 211 and 221, and the surfaces of the paper layers 211 and 221 are covered with a layer of laundry starch 214a. As a result, when the laundry starch 214a dries and hardens, the surfaces of the paper layers 211 and 221 are coated with a layer of laundry starch 214a, and the mulberry fibers and pulp fibers that make up the paper layers 211 and 221 are strongly bonded together by the components of the laundry starch 214a that have permeated them, thereby improving the rigidity, strength, and durability of the paper layers 211 and 221.

[0086] Furthermore, by improving the rigidity, strength, and durability of the paper layers 211 and 221, it becomes possible to polish them with sandpaper or the like. This allows for a smooth surface to be obtained. For example, when putting on or taking off clothing, it reduces the likelihood of the clothing catching on the torso portion 2, allowing for smoother donning and doffing. In addition, the adhesive G between the front portion 21 and the back portion 22, and the adhesive G around the fitting portion 71 can be made less noticeable.

[0087] As shown in Figure 11(c), after the base layers 214 and 224 have hardened, the filler layers 215 and 225 are laminated onto the base layers 214 and 224, respectively. For the build-up layers 215 and 225, a putty-like build-up material 215a can be used, which is obtained by further blending hemp fibers and polishing powder with the aforementioned laundry starch 214a. The build-up layers 215 and 225 are formed by applying the build-up material 215a to the entire surface of the base layers 214 and 224 using a silicone spatula or the like.

[0088] In addition, in the build-up material 215a, the mixing ratio of laundry starch 214a to abrasive powder is preferably in the range of 1:1 to 1:1.5 by mass. Furthermore, it is preferable to mix in about 1 to 2 tablespoons of hemp fiber per 100 ml of laundry starch.

[0089] Here, the build-up layers 215 and 225 are formed by repeatedly applying and drying the build-up material 215a onto the base layers 214 and 224, thereby creating multiple layers. In this embodiment, the amount of hemp fibers contained in the filler material 215a is different on the side of the base layers 214 and 224 (lower layer side) and on the surface side away from the base layers 214 and 224 (upper layer side).

[0090] For example, on the base layers 214 and 224, the amount of hemp fibers is increased to raise the viscosity of the filler material 215a. This makes it less prone to cracking even when the filler material 215a is applied thickly, and also improves the strength of the filler layers 215 and 225. Furthermore, the thickness of the filler layers 215 and 225 can be varied. As a result, realistic bumps and depressions that closely resemble the shape of the human body can be formed.

[0091] Furthermore, on the surface side (upper layer side) away from the base layers 214 and 224, the amount of hemp fibers contained in the build-up material 215a can be reduced, or it can be made without hemp fibers. As a result, the abrasive powder contained in the build-up material 215a fills the gaps on the surface, and a smooth surface can be obtained by polishing with sandpaper or the like.

[0092] As a result, the paper layers 211 and 221 are sandwiched between layers containing hemp fibers on the inside and outside, thereby improving the rigidity and strength of the body section 2.

[0093] As shown in Figure 11(d), after the build-up layers 215 and 225 have hardened, coating layers 216 and 226 are laminated onto the build-up layers 215 and 225, respectively. Water-based paint 216a can be used for the coating layers 216 and 226. Water-based paint 216a has less impact on the human body than, for example, lacquer paint.

[0094] The coating layers 216 and 226 are formed by applying water-based paint 216a to the entire surface of the build-up layers 215 and 225 using a spray or the like. Alternatively, a primer such as a sanding sealer may be applied to the build-up layers 215 and 225 before applying the water-based paint 216a. This improves the adhesion of the water-based paint 216a.

[0095] The water-based paint 216a hardens as the resin dries, forming a film. Therefore, the coating layers 216 and 226 that are laminated on the build-up layers 215 and 225 are resin films, which can improve the durability of the fuselage 2.

[0096] Furthermore, the coating layers 216 and 226 can be polished with sandpaper or the like to give the surface a glossy finish. This enhances the texture of the fuselage 2.

[0097] As a result, the front section 21 and the rear section 22 of the fuselage section 2 each have a structure in which six layers are stacked (see Figures 3(a) and 3(b)). In this embodiment, the following modifications are made to enhance the rigidity and strength of each layer. (a) In paper layers 211 and 221, mulberry fibers and pulp fibers are blended in a mass ratio ranging from 1:1 to 1:3. (b) The linen layers 212, 222 and the reinforced layers 215, 225 contain linen fibers, which are high-strength fibers. (c) A vinyl acetate-based adhesive 213a is interposed between the paper layers 211, 221 and the linen layers 212, 222, so that the mulberry fibers and linen fibers can be mixed together. (d) Laundry starch is used in the base layers 214 and 224 to stiffen the fibers. (e) Coating layers 216 and 226 use water-based paints that form a film upon drying. In this way, the torso section 2, even though it is made of paper, has high rigidity and strength.

[0098] Although a detailed explanation will be omitted, the arm section 3, hand section 4, and leg section 5 (see Figure 1) each have six layers (the first to sixth layers) made of the same material as the torso section 2, and are highly rigid and strong despite being made of paper. This makes it possible to increase the rigidity and strength of the paper mannequin 1.

[0099] Here, mannequins made of FRP (fiber-reinforced plastic) contain organic solvents and glass fibers, which are harmful to both the human body and the environment. On the other hand, the mannequin doll 1 according to the embodiment uses paper, hemp, vinyl acetate-based adhesive, laundry starch containing PVA, polishing powder, and water-based paint as materials. Thus, since the mannequin doll 1 is made mainly from natural materials and does not contain harmful substances, it has little impact on the human body and the environment.

[0100] In this embodiment, a mannequin doll 1 having a head (not shown) is used as an example, but the invention is not limited to this embodiment. For example, a mannequin doll without a head (headless mannequin) may also be used. In the case of a headless mannequin doll, the build-up material 215a (see Figure 11(c)) can be applied in layers over the entire surface of the fitting portion 71T for the head.

[0101] The mannequin doll 1 according to the present invention has the following configuration. (1) A paper mannequin doll 1 containing mulberry fiber and pulp fiber. The mixing ratio of mulberry fiber to pulp fiber is in the range of 1:1 to 1:3 by mass.

[0102] This configuration allows for increased rigidity and strength in the paper mannequin 1.

[0103] (2) A layer of paper 211 (first layer) containing mulberry fibers and pulp fibers is laminated with a layer of hemp cloth 212 (second layer) containing hemp fibers.

[0104] By constructing it in this way and layering a hemp cloth layer 212 containing hemp fibers, which are high-strength fibers, on top of a paper layer 211, the rigidity and strength of the paper mannequin doll 1 can be further increased.

[0105] (3) Between the paper layer 211 and the linen layer 212, there is an adhesive layer 213 (third layer) composed of vinyl acetate adhesive 213a.

[0106] Vinyl acetate adhesives are emulsions in which vinyl acetate monomer is dispersed in water, resulting in low emissions of volatile organic compounds (VOCs) and minimizing the burden on the environment and human health. Furthermore, vinyl acetate adhesives dry quickly and become stronger once dry, making them particularly suitable for porous materials such as wood, paper, and fabric. Therefore, with the above configuration, the surface of the paper layer 211 becomes moist, improving adhesion with the linen layer 212. Specifically, by impregnating the linen 212a with adhesive 213a, the mulberry fibers of the paper layer 211 and the fibers of the linen 212a mix together, improving the rigidity of the paper layer 211. This further increases the rigidity of the paper mannequin doll 1.

[0107] (4) On the paper layer 211, a base layer 214 (fourth layer) made of laundry starch 214a containing PVA (polyvinyl alcohol) is laminated from the opposite side of the linen layer 212.

[0108] With this configuration, the laundry starch 214a penetrates between the mulberry fibers and pulp fibers that make up the paper layer 211, and the surface of the paper layer 211 is covered with a layer of laundry starch 214a. As a result, when the laundry starch 214a dries and hardens, the surface of the paper layer 211 is coated with a layer of laundry starch 214a, and the mulberry fibers and pulp fibers that make up the paper layer 211 are strongly bonded together by the components of the laundry starch 214a that have permeated them, thereby improving the rigidity, strength and durability of the paper layers 211 and 221. By improving the rigidity, strength, and durability of the paper layer 211, it becomes possible to polish it with sandpaper or the like. This allows for a smooth surface to be obtained, making it easier to put on and take off clothes on the mannequin doll 1.

[0109] (5) The base layer 214 is further laminated with a build-up layer 215 (the fifth layer) which is made of a build-up material 215a which is a mixture of laundry starch 214a, hemp fibers and polishing powder.

[0110] In this configuration, the linen layer 212 is located inside the paper layer 211, and the hemp fiber-containing filler layer 215 is located on the outside. As a result, the paper layer 211 is sandwiched between layers containing hemp fibers on the inside and outside, which further increases the rigid strength of the mannequin doll 1. Furthermore, the inclusion of hemp fibers increases the viscosity of the build-up material 215a, allowing for thicker application. This enables variations in the thickness of the build-up layer 215. As a result, realistic contours that closely resemble the shape of the human body can be formed. Furthermore, the abrasive powder contained in the build-up material 215a fills the gaps on the surface, so a smooth surface can be obtained by polishing it with sandpaper or the like.

[0111] (6) The build-up material 215a that constitutes the build-up layer 215 is The mixing ratio of laundry starch 214a to polishing powder is in the range of laundry starch:polishing powder = 1:1 to 1:1.5 by mass. The amount of hemp fibers contained in the filler material 215a is greater on the sublayer 214 side than on the surface side.

[0112] This configuration makes it less prone to cracking even when the build-up material 215a is applied thickly, and also improves the strength of the build-up layers 215 and 225. Furthermore, it allows for variations in the thickness of the build-up layers 215 and 225. As a result, it is possible to create realistic bumps and depressions that closely resemble the shape of the human body.

[0113] (7) A coating layer 216 (sixth layer) made of water-based paint 216a is further laminated on the build-up layer 215.

[0114] Water-based paint 216a hardens as the resin dries, forming a protective film. Therefore, by configuring it as described above, the durability of mannequin 1 can be improved.

[0115] Although embodiments of the present invention have been described above, the present invention is not limited to the embodiments shown. It can be modified as appropriate within the scope of the technical idea of ​​the invention. [Explanation of symbols]
