Description

[Technical Field]

[0001] The present invention relates to a torso. [Background technology]

[0002] When displaying clothing in a store, a torso, a type of human model with the head, arms, and legs omitted, is sometimes used. For example, Patent Document 1 discloses a mannequin with a core made of cardboard to which multiple parts with a multifaceted structure are attached. The mannequin described in Patent Document 1 is formed by preparing multiple types of cores and parts, and selecting a combination of cores and parts according to the physical characteristics of each gender.

[0003] Additionally, for example, Patent Document 2 discloses a body in which a panel plate for forming a body, which is made of a single plastic sheet or hard cardboard, is punched out and folded into a cylindrical shape, and hooks and fastening pieces arranged on the panel plate are fastened at predetermined positions depending on the gender and purpose to form the shoulders, chest, back, and torso. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2014-30644 [Patent Document 2] Patent No. 3640919 Summary of the Invention [Problem to be solved by the invention]

[0005] The mannequin disclosed in Patent Document 1 has a multifaceted shape formed using multiple parts, and therefore has poor reproducibility of the curvaceous characteristics of the human body. In particular, the mannequin disclosed in Patent Document 1 has difficulty expressing the differences in body lines according to gender.

[0006] The body disclosed in the above-mentioned Patent Document 2 maintains its three-dimensional shape by the elasticity and flexibility of the body-forming panel board made of a single plastic sheet or hard cardboard. However, the body disclosed in Patent Document 2 is hollow inside, has no supporting structure, and is structured so that the body alone maintains its shape, which means that it has problems with strength, such as difficulty in maintaining its shape when subjected to loads from heavy clothing, etc.

[0007] The present invention has been made in consideration of the above circumstances, and has an object to provide a torso that has a simple structure and is highly reproducible in terms of the expression of body shapes according to gender. [Means for solving the problem]

[0008] The torso according to the present invention comprises a support body made of corrugated cardboard and having a three-dimensional shape, including an abdominal core, a chest core body continuing from the upper end of the abdominal core, and a pair of shoulder core body parts protruding from the left and right ends of the chest core, and an exterior sheet having a sheet shape capable of covering the front part of the support body and including an abdominal surface forming part arranged at least in front of the abdominal core body, a chest surface forming part formed continuously with the upper end of the abdominal surface forming part and arranged in front of the chest core body, and shoulder surface forming parts formed to protrude in the left and right directions from the left and right ends of the chest surface forming part and to cover the shoulder core body, wherein the length in the width direction of the abdominal core body is shorter than the length in the width direction of the chest core body, and the chest core body is the outer sheet has a pair of shoulder cutouts formed along the boundary between the chest surface forming portion and the shoulder surface forming portion from the outer edge of the outer sheet toward the top of the shoulder surface forming portion, and the shoulders are formed by overlapping the attachment portion on the shoulder surface forming portion side with the back surface of the attachment portion on the chest surface forming portion side along the shoulder cutouts, and the outer sheet projects outward along the front end of the chest core portion between the upper end of the chest surface forming portion and the boundary portion between the chest surface forming portion and the abdominal surface forming portion, and the abdominal surface forming portion covers the side surface of the abdominal core portion and is attached to the back surface of the abdominal core portion.

[0009] With the above configuration, the torso can be formed with a curved surface using a sheet-shaped exterior sheet, allowing for highly reproducible body lines that closely resemble those of an actual male body. The torso can be strengthened by providing a support that corresponds to the overall framework. The torso can be formed using a small number of parts, as it can be formed using a single exterior sheet and a cardboard member that forms the support. The torso is configured so that the width of the abdominal core is shorter than the width of the chest core, and the chest core is configured to protrude outward, allowing for a more accurate representation of a man's body shape from the chest to the abdomen. The torso has shoulders formed by attaching the attachment part on the shoulder surface forming part to the back of the attachment part on the chest surface forming part along the shoulder incisions, and the exterior sheet protrudes outward along the front end of the chest core between the upper end of the chest surface forming part and the boundary between the chest surface forming part and the abdominal surface forming part. This configuration makes it possible to accurately reproduce the characteristics of a man's side body, where the side part from the shoulders to the armpits and chest is bulging outward. The torso is formed so that the chest core of the support protrudes outward, and the outer sheet protrudes outward along the front end of the chest core between the upper end of the chest surface forming part and the boundary between the chest surface forming part and the abdominal surface forming part, giving the chest a shape that stretches forward, expressing the area corresponding to the chest plate and allowing for highly reproducible representation of the characteristics of a man's chest. The torso has an abdominal surface forming part positioned in front of the abdominal core, which creates a curved line from the chest to the abdomen, allowing for highly reproducible representation of the characteristics of a man's abdominal line. The torso can improve the reproducibility of the shape characteristics around a man's abdomen by having the abdominal surface forming portion of the exterior sheet cover the front and sides of the abdominal core and attach it to the back of the abdominal core. As described above, the torso can accurately represent the male physique by the method of attaching the exterior sheet to the support body and the shapes of the support body and the exterior sheet when molding the torso.

[0010] The torso according to the present invention comprises a three-dimensional corrugated cardboard support body including an abdominal core, a chest core body located above the abdominal core body, and a pair of shoulder core body parts protruding from the left and right ends of the chest core body, and an exterior sheet having a sheet shape capable of covering the front part of the support body and including an abdominal surface forming part located at least in front of the abdominal core body, a chest surface forming part formed continuously with the upper end of the abdominal surface forming part and located in front of the chest core body, and shoulder surface forming parts formed protruding in the left and right directions from the left and right ends of the chest surface forming part and covering the shoulder core body, and the support body is configured to attach the pair of shoulder core body parts to chest parts forming the chest core body. The chest core and the pair of shoulder cores are formed by inserting shoulder parts that form the shoulder core, the pair of shoulder cores are formed at an angle so that the protruding ends of the pair of shoulder cores are located approximately in the middle in the height direction of the chest core, the chest surface forming part has a protrusion that protrudes forward approximately in the middle in the height direction, the abdominal surface forming part and a part of the chest surface forming part each cover the side of the abdominal core and are arranged with both ends pasted together on the back of the abdominal core, and the shoulders of the shoulder surface forming parts are formed by pasting part of the lower end of the shoulder surface forming part to the surface of the chest surface forming part.

[0011] With the above configuration, the torso can be curved using a sheet-shaped exterior sheet, allowing it to accurately reproduce the lines of a real woman's body. The torso can be strengthened by providing a support that corresponds to the overall framework. The torso can be formed using a small number of parts because it can be formed using a single exterior sheet and cardboard members that form the support. The torso is formed with a pair of shoulder cores that are inclined so that the protruding ends of the pair of shoulder cores are located approximately midway in the height direction of the chest core, thereby enabling highly reproducible reproduction of the characteristics of a woman's shoulders, such as a line that slopes gently downward from the shoulders to the arms. The torso has a protrusion that protrudes forward at approximately the middle of the height of the chest surface forming part, which allows for highly reproducible reproduction of the characteristics of a woman's body shape from the chest to the abdomen, such as the lines and curves from the chest to the abdomen. The torso is configured so that the abdominal surface forming portion and part of the chest surface forming portion of the outer sheet cover the sides of the abdominal core and both ends are attached to the back of the abdominal core, thereby improving the reproducibility of the shape characteristics around a woman's abdomen. The torso is constructed so that the shoulders are formed by bonding part of the lower end of the shoulder surface forming part to the surface of the chest surface forming part, which gives the line from the shoulder to the arm a gentle downward slope, allowing for highly reproducible representation of the characteristics of a woman's shoulders, which are narrower than those of a man. As described above, the female torso can accurately represent the female figure by using the shapes of the support body and exterior sheet when molding the torso.

[0012] In the torso according to the present invention, the support body may have a positioning notch formed thereon to indicate the attachment position of the support body and the exterior sheet, the support body may have a positioning section printed thereon to indicate the attachment position of the exterior sheet, and the exterior sheet may have cut sections formed thereon to indicate the attachment position of the support body or the attachment positions of both ends of the abdominal surface forming section and a part of the chest surface forming section.

[0013] With the above-described configuration, the torso can be molded accurately because the positioning notches formed in the support allow the exterior sheet to be attached to the support in the correct position without deviation. The torso can be formed accurately by attaching the exterior sheet to the support in accordance with the positioning portion printed on the support, so that the support and the exterior sheet can be attached without misalignment of the attachment position. The torso can be accurately molded because the cut portions formed in the exterior sheet allow the exterior sheet to be accurately attached to the support or to each other. Furthermore, even if the cut portions are formed in positions that are easily visible from the outside, such as the front or side of the torso, at positions where the exterior sheet is attached to the support or where the exterior sheets are attached to each other, the cut portions are configured to be inconspicuous even when the torso is in use, and therefore are not noticeable, thereby improving the aesthetic appearance of the torso.

[0014] In the torso according to the present invention, the exterior sheet may be formed of a sheet material containing polypropylene.

[0015] With the above configuration, the torso is made of a combination of a sheet containing polypropylene and cardboard, which can further increase the load-bearing capacity due to the weight of the attached clothing, etc. In addition, since the outer sheet of the male torso contains polypropylene, the burst strength of the outer sheet can be further increased.

[0016] In the torso according to the present invention, the abdominal surface forming portion may be formed with an abdominal surface attachment tab for attaching the abdominal surface forming portion to the abdominal core portion or at least one of the abdominal surface forming portions to each other, and the chest surface forming portion may be formed with a chest surface attachment tab for attaching the chest surface forming portion to the chest core portion or at least one of the chest surface forming portions to each other.

[0017] With the above configuration, the abdominal surface attachment tab and the chest surface attachment tab guide the attachment position between the exterior sheet and the support body or between the exterior sheets, so that the torso can be easily assembled into a predetermined shape.

[0018] The torso according to the present invention may include a base that supports the support body in an upright position.

[0019] With the above configuration, the torso is stably supported in an upright position. [Effects of the Invention]

[0020] According to the present invention, it is possible to provide a torso with a simple configuration that is highly reproducible in terms of the expression of body shapes according to gender. [Brief explanation of the drawings]

[0073] The first body part 31, the second body part 32, and the third body part 33 are formed symmetrically with respect to the center line in the left-right direction A. The first body part 31, the second body part 32, and the third body part 33 are formed from a single sheet of corrugated cardboard. Of the folding lines formed on the first body part 31 and the third body part 33, folding lines 313a and 313b are formed by known perforations.

[0074] A method for assembling the support body 3 will be described below with reference to Figures 6 to 8. The support body 3 is assembled by following the numbers in the first procedure instruction sections 319c, 323a, and 337b printed on one side 319, 323, and 337 of each part. First, one side 319 of the first main body part 31 is placed face down (facing the placement surface), and the left and right sections 314a and 314b are folded in a mountain fold along the folding lines 313a and 313b until they are perpendicular to the center section 314c. Creases are then made along the folding lines 313a and 313b. By folding along the folding lines 313a and 313b, the left and right sections 314a and 314b can stand perpendicular to the center section 314c.

[0075] With the left portion 314a and the right portion 314b standing perpendicular to the center portion 314c, the second body part 32 is attached to the first body part 31. The second body part 32 is arranged with one surface 323 facing the upper end 31e, and the left insertion portion 322a and the right insertion portion 322b are inserted into the first body part 31 along the right second insertion portion 311e and the left second insertion portion 311b. The second body part 32 is inserted deep enough that the inner ends of the insertion portions come into contact.

[0076] While pressing the bottom surface portion 315a, the first main body part 31 is bent in a mountain fold direction along the folding lines 313c and 313d, and the first forming portion 31a is raised up toward the second forming portion 31b. After the first forming portion 31a is raised up, the second forming portion 31b is successively bent in a mountain fold direction along the folding lines 313e, 313f, and 313g to form creases.

[0077] After creating creases in second forming portion 31b, second forming portion 31b is folded along folding lines 313e, 313f, and 313g, and inserting portion 315c is inserted with left fifth inserting portion 311h and right fifth inserting portion 311i aligned with left third inserting portion 311c and right third inserting portion 311f. Inserting portion 315c is performed to a depth where the innermost ends of the inserting portions abut, similar to second main body part 32. By the above procedure, base 3d is formed.

[0078] With one surface 337 facing downward, the left insertion portion 332a and the right insertion portion 332b of the first forming portion 33a of the third main body part 33 are inserted into the left first insertion portion 311a and the right first insertion portion 311d of the first main body part 31. The first forming portion 33a is inserted to a depth where the inner ends of the insertion portions come into contact with each other, similar to the second main body part 32 and the insertion portion 315c.

[0079] After the first forming portion 33a is inserted into the first main body part 31, the third main body part 33 is bent in a mountain fold direction along the bending line 333a. After the third main body part 33 is bent along the bending line 333a, the bending line 333b is bent along the corners 31j, 31j of the upper left corner 31g and the upper right corner 31m, and the bending line 333c is bent along the corners 31k, 31k .... After folding the third body part 33 along the folding line 333c, the third body part 33 is folded along the folding lines 333d and 333e located on the left end 31h and the right end 31n, and the folding lines 333d and 333e and the continuous portion 33g are abutted against the left end 31h and the right end 31n.

[0080] After the third body part 33 is folded along the folding lines 333d and 333e, the second forming portion 33b located between the folding lines 333d and 333e and the folding lines 333f and 333g is brought into contact with the upper end 31e of the first body part 31. The third body part 33 is then folded in a mountain fold direction along folding lines 333f and 333g located at intersections 317e and 317f between the folding lines 333a and 333b and the upper end 31e. By folding the third body part 33 along the folding lines 333f and 333g, the fourth forming portion 33d is bent downward in the Z direction by approximately 90 degrees from the folding lines 333f and 333g at positions where the folding lines 333f and 333g contact the upper end 31e, and the fourth forming portion 33d is positioned to abut against the central portion 314c. The second forming portion 33b of the third body part 33 is disposed on the first forming portion 31a of the first body part 31, and the fourth forming portion 33d of the third body part 33 is disposed on the central portion 314c.

[0081] The third forming portion 33c is cut out from the notch 335 by bending along the bending lines 333d and 333e of the third main body part 33 and positioned so as to abut on the upper end 31e, and is bent along the bending lines 333f and 333g so as to be continuous with the fourth forming portion 33d without being bent, and is extended upward in a state where it stands approximately 90 degrees upward in the Z direction relative to the upper end 31e.

[0082] After placing the fourth forming portion 33d on the central portion 314c, the fourth forming portion 33d is folded in a mountain fold direction along the folding line 333i, and the insertion portion 336c is inserted into the fourth insertion portion 311g. The insertion portion 336c is inserted until the lower end 336d, which is not continuous with the insertion portion 336c of the second spine 336b, abuts against the central portion 314c.

[0083] After the insertion portion 336c is inserted into the fourth insertion portion 311g, the third forming portion 33c is bent approximately 90 degrees in a mountain fold direction along the bending line 333h. By bending the third forming portion 33c along the bending line 333h, the portion of the third forming portion 33c from the bending line 333h to the tip side is positioned above the upper end 31e of the first main body part 31.

[0084] The support body 3 of the male torso 1 is formed as described above. The front portion of the abdominal core portion 3a of the support body 3 is formed by the left end portion 31c and right end portion 31d of the first forming portion 31a. The back portion of the abdominal core portion 3a is formed by the region 31t between the lower end 31f of the central portion 314c of the first forming portion 31a and the fourth insertion portion 311g. The central portion 314c of the first forming portion 31a extends in the Z direction along the back portion of the abdominal core portion 3a.

[0085] The front portion of the chest core 3b of the support body 3 is formed by a region 33k extending from the folding line 333a to the folding lines 333d and 333e of the second forming portion 33b of the third main body part 33, which is located on the upper left corner 31g and upper right corner 31m of the first main body part 31. The back portion of the chest core 3b is formed by the first back portion 336a and the second back portion 336b of the third main body part 33.

[0086] The pair of shoulder core portions 3c, 3c of the support body 3 are formed by the protruding portion 33f and the generally fan-shaped protruding portions 336e, 336e protruding on both sides in the width direction X of the first spine portion 336a, respectively.

[0087] The base 3d of the support body 3 is formed by folding and inserting the second forming portion 31b into the first forming portion 31a of the first main body part 31. The base 3d is placed on the installation surface F, and the support body 3 is raised to support a component located above the base 3d.

[0088] In the following description, when the male torso 1 is placed on the installation surface F, the side on which the front portions of the abdominal core 3a, chest core 3b, and shoulder core 3c are formed is referred to as the front portion 3e, and the side on which the back portions of the abdominal core 3a, chest core 3b, and shoulder core 3c are formed is referred to as the back portion 3f.

[0089] The base 3d has a forward protruding portion 3g and a rearward protruding portion 3h. The forward protruding portion 3g is formed by separating the base portion 315b and the bottom surface portion 315a of the second forming portion 31b of the first main body part 31 at the cutout portion 316d, so that the arc-shaped lower tip of the bottom surface portion 315a protrudes toward the front portion 3e in the front-to-rear direction Y. The rearward protruding portion 3h is formed by separating the bottom surface portion 315a of the second forming portion 31b from the first forming portion 31a of the first main body part 31 at the cutout portion 316a, so that the upper tip of the rounded rectangular shape of the bottom surface portion 315a protrudes toward the back portion 3f in the front-to-rear direction Y. The contact area of ​​the bottom surface portion 315a with the installation surface F of the base 3d may be changed depending on the size of the support body 3, as long as the support body 3 can be supported upright.

[0090] The length in the width direction X of the upper end (bending line 313g) of the base 3d is longer than the length in the width direction X of the abdominal core portion 3a (central portion 314c), and the abdominal core portion 3a stands perpendicular to the base 3d, so the base 3d can provide more stable support for each part.

[0091] The front part of the chest core 3b is formed with a second forming part 33b located above the upper left corner 31g and upper right corner 31m of the first forming part 31a, protruding outward by corners 31j and 31k.

[0092] The support body 3 is formed by the first main body part 31 and the second forming portion 33b and first back portion 336a of the third main body part 33 so that the length of the chest core part 3b in the width direction X is longer than the length of the abdominal core part 3a in the width direction X. In the back portion 3f of the support body 3, the first back portion 336a and second back portion 336b of the third main body part 33 are arranged on the central portion 314c of the first main body part 31, so that the third main body part 33 protrudes toward the back portion 3f in the front-to-back direction Y relative to the first main body part 31. The first back portion 336a and the second back portion 336b form the protruding portion 336e of the support body 3.

[0093] Support body 3 is formed by assembling multiple cardboard parts by folding them along the folds and inserting them into each other's slots, without the need for adhesives or other connectors. Despite its simple structure, support body 3 expresses the distinctive features of a man's body shape from the shoulders to the abdomen.

[0094] As shown in Figure 9, the exterior sheet 4 includes an abdominal surface forming portion 41, a chest surface forming portion 42, and a pair of shoulder surface forming portions 43, 43. The exterior sheet 4 has a sheet shape that allows curved surfaces to be formed without creating creases. The chest surface forming portion 42 is formed continuously with the upper end of the abdominal surface forming portion 41, and the pair of shoulder surface forming portions 43, 43 are formed to protrude in the right direction A1 and the left direction A2 from both ends of the chest surface forming portion 42 in the left-right direction A, respectively.

[0095] The exterior sheet 4 is made of a paper material mixed with polypropylene (hereinafter referred to as "PP paper"). The exterior sheet 4 is not limited to PP paper as long as it has the desired deformability to express curves and roundness and durability against breakage such as tearing.

The shoulder surface forming portion 43 protrudes slightly downward from the intersection 4g between the shoulder surface forming portion 43 and the curved portion 4e toward the lower end 43d. The shoulder surface forming portion 43 is formed so that the inclination of the upper end 43b and the inclination of the inclined portion 411d are approximately the same.

[0105] The shoulder surface forming portion 43 has a cut portion 433 formed on the other surface 4f opposite the one surface 4b, in a position close to the shoulder cut portion 431, which is a cut line that indicates the position where the exterior sheet 4 is attached. Hereinafter, the cut portion 433 will be referred to as the cut portion 433. The cut portion 433 has an upper cut portion 433a that roughly coincides with the path of the upper shoulder cut portion 431a and a lower cut portion 433b that roughly coincides with the path of the lower shoulder cut portion 431b. The cut portion 433 may be configured to be printed on the exterior sheet 4 with a design similar to that of the positioning portions 319a and 337a of the support body 3.

[0106] On the other surface 4f of the shoulder surface forming portion 43, an upper double-sided tape 435a is attached in a position adjacent to the upper end 43b of the upper attachment portion 434a between the upper shoulder cutout 431a and the upper cutout 433a. A lower double-sided tape 435b is attached in a position adjacent to the lower end 43d of the lower attachment portion 434b between the lower shoulder cutout 431b and the lower cutout 433b.

[0107] 1 and 2 and 9 and 10, a method for attaching the exterior sheet 4 to the support body 3 of the male torso 1 will be described. The exterior sheet 4 is attached to the support body 3 after the support body 3 has been formed by combining the main body parts 31, 32, and 33. The exterior sheet 4 is attached to the support body 3 in accordance with the numbers in the second procedure instruction sections 319d and 337c printed on one side 319 and one side 337 of the first main body part 31 and the third main body part 33, respectively.

[0108] First, the exterior sheet 4 is placed on the front part 3e of the support body 3 in the orientation shown in Figure 9. The pair of chest attachment tabs 422a, 422a of the exterior sheet 4 is placed on the back part 3f side of the support body 3, and the edges of the chest attachment tabs 422a are aligned with the pair of positioning portions 337a, 337a printed on the left and right ends of the first back part 336a and attached with double-sided tape 424. The pair of chest attachment tabs 422a, 422a are attached to the back surface of the chest core part 3b of the support body 3.

[0109] After the pair of chest surface attachment tabs 422a, 422a are attached, the position of the notch 413 of the exterior sheet 4 is aligned with the positioning notch 319b of the support body 3. Specifically, the horizontal cut of the positioning notch 319b is aligned with the lower end 41a of the first abdominal surface attachment tab 412a, and the upper end of the vertical cut of the positioning notch 319b is aligned with the apex of the triangle of the notch 413.

[0110] After aligning the position of the notch 413 with the position of the positioning notch 319b, the first abdominal surface attachment tab 412a of the exterior sheet 4 is attached to the base part 315b of the second forming part 31b with double-sided tape 414. The attachment position of the first abdominal surface attachment tab 412a is the front surface of the abdominal core part 3a of the support body 3.

[0111] After attaching the first abdominal surface attachment tab 412a, the left portion 41b and right portion 41c of the abdominal surface forming portion 41 are placed on the spine 3f side of the support body 3. The exterior sheet 4 is attached with double-sided tape 414 so that the two pairs of second abdominal surface attachment tabs 412b, 412b align with the pair of positioning portions 319a, 319a printed on the central portion 314c of the first forming portion 31a and the pair of positioning portions 337a, 337a printed in the central portion of the second spine 336b. The attachment positions of the two pairs of second abdominal surface attachment tabs 412b, 412b are the back surface of the abdominal core portion 3a of the support body 3.

[0112] The exterior sheet 4 is attached to the support body 3 using the above procedure. One surface 4b of the exterior sheet 4 becomes the back surface 4b, and the other surface 4f becomes the front surface 4f. After attaching the two pairs of second abdominal surface attachment tabs 412b, 412b, the upper attachment portion 434a of the shoulder surface forming portion 43 is moved toward the back surface 4b, and the upper shoulder notch 431a and the upper cutout 433a are aligned. The front surface 4f of the upper attachment portion 434a is overlapped with the back surface 4b of the chest surface forming portion 42 and attached with the upper double-sided tape 435a. The lower attachment portion 434b of the shoulder surface forming portion 43 is similarly moved toward the back surface 4b, and the lower shoulder notch 431b and the lower cutout 433b are aligned. The front surface 4f of the lower attachment portion 434b is overlapped with the back surface 4b of the chest surface forming portion 42 and attached with the lower double-sided tape 435b. The above procedure is performed for both pairs of shoulder surface forming portions 43, 43.

[0113] By the above procedure, the back surface 4b of the chest surface forming portion 42 and the surfaces 4f of the pair of shoulder surface forming portions 43, 43 are bonded together to form the shoulder portions 11 of the male torso 1. The shoulder portions 11 are inclined downward at an angle of 23° to 29° relative to the horizontal when viewed from the front, for example.

[0114] The inclination angle of the inclined portions 334c, 334d of the first back portion 336a of the third main body part 33 is greater than the inclination angle of the shoulder surface forming portion 43 of the exterior sheet 4 that is disposed above the inclined portions 334c, 334d. Therefore, in the male torso 1, the inclined portions 334c, 334d are positioned below the upper end of the shoulder surface forming portion 43. The inclined portions 334c, 334d are inclined downward, for example, by 32° to 38° relative to the left-right direction B.

[0115] The male torso 1 includes a neck part 5. The neck part 5 is formed in a rectangular shape with the length of one side 5a substantially matching the overall length of the curved part of the cutout 335 of the third forming part 33c. The neck part 5 is made of PP paper, just like the exterior sheet 4.

[0116] In the male torso 1, a neck insertion hole 3i that substantially matches the shape of the third forming portion 33c is formed by folding the third main body part 33 along the folding lines 333f, 333g. The shape of the neck insertion portion 423 formed in the chest surface forming portion 42 of the outer sheet 4 substantially matches the shape of the neck insertion hole 3i. Therefore, in the male torso 1 in which the outer sheet 4 is attached to the support body 3 at a desired position, the neck insertion hole 3i is formed at the upper end of the outer sheet 4.

[0117] The male torso 1 has the neck part 5 rounded so that one side 5a faces the neck insertion hole 3i to match the shape of the edge of the neck insertion hole 3i, and the other side 5b of the side 5a is inserted about halfway into the neck insertion hole 3i.

[0118] In the male torso 1, the third forming portion 33c extending upward from the support 3 is bent along the bending line 333h toward the neck insertion hole 3i, and a neck insertion groove 3j having a width approximately equal to the thickness of the neck part 5 is formed.

[0119] While holding the third forming portion 33c bent along the bending line 333h, the male torso 1 inserts the neck part 5 into the neck insertion groove 3j until the neck part 5 is attached to the neck insertion groove 3j by its elastic behavior in the direction of returning from the curved surface of the neck part 5 to a flat surface, and the neck part 1a is formed.

[0120] Through the above procedure, the male torso 1 is formed and the front portion 3e of the support body 3 is covered. In the male torso 1, the left portion 41b and right portion 41c of the abdominal surface forming portion 41 of the exterior sheet 4 cover the sides of the abdominal core portion 3a of the support body 3, and the central portion 41d is positioned in front of the abdominal core portion 3a. The chest surface forming portion 42 is positioned in front of the chest core portion 3b of the support body 3. The pair of shoulder surface forming portions 43, 43 are positioned above the pair of shoulder core portions 3c, 3c of the support body 3 to form the shoulder portion 11 and cover the pair of shoulder core portions 3c, 3c.

[0121] The exterior sheet 4 protrudes outward between the upper end 42a of the chest surface forming portion 42 and the connecting portion 4a between the chest surface forming portion 42 and the abdominal surface forming portion 41, along the protruding shape formed by the upper left corner 31g and the upper right corner 31m of the first main body part 31 formed on the front end surface 3k of the chest core portion 3b.

[0122] Next, the effects of the male torso 1 according to the embodiment of the present invention will be described.

[0123] The male torso 1 is formed by attaching a sheet-shaped exterior sheet 4 to a cardboard support body 3, which has an abdominal core 3a, a chest core 3b, and a pair of shoulder cores 3c, 3c, so that the sheet-shaped exterior sheet 4 covers the front portion 3e. The chest core 3b of the support body 3 has a second forming portion 33b, the front portion of which is located above the upper left corner 31g and upper right corner 31m of the first forming portion 31a, and which protrudes outward at corners 31j, 31k. The support body 3 is formed by the first main body part 31, the second forming portion 33b of the third main body part 33, and the first back portion 336a, so that the length in the width direction X of the chest core 3b is longer than the length in the width direction X of the abdominal core 3a.

[0124] The exterior sheet 4 has an abdominal surface forming portion 41 arranged in front of the support body 3, a chest surface forming portion 42 arranged in front of the chest core portion 3b of the support body 3, and a pair of shoulder surface forming portions 43, 43 formed to cover a pair of shoulder core portions 3c, 3c of the support body 3. The left and right portions 41b, 41c of the abdominal surface forming portion 41 of the exterior sheet 4 cover the sides of the abdominal core portion 3a, and the central portion 41d is arranged in front of the abdominal core portion 3a, with both ends of the left and right portions 41b, 41c attached to the back portion 3f of the abdominal core portion 3a. Between the upper end 42a of the chest surface forming portion 42 and the connecting portion 4a between the chest surface forming portion 42 and the abdominal surface forming portion 41, the exterior sheet 4 protrudes outward along the protruding shape formed by the upper left corner 31g and upper right corner 31m of the first main body part 31 formed on the front end surface 3k of the chest core portion 3b. The exterior sheet 4 is provided with shoulder cutouts 431, each consisting of an upper shoulder cutout 431a formed from an upper end 43b of the outer edge 43a toward an apex 43c on the chest surface forming portion 42 side of the shoulder surface forming portion 43, and a lower shoulder cutout 431b formed from a lower end 43d of the outer edge 43a toward the apex 43c, in both of the pair of shoulder surface forming portions 43. For the male torso 1, the upper attachment portion 434a and the lower attachment portion 434b are moved toward the back surface 4b of the chest surface forming portion 42 in both of the pair of shoulder surface forming portions 43, and the positions of the upper shoulder cutout 431a and the upper cutout 433a and the lower shoulder cutout 431b and the lower cutout 433b are aligned, respectively. Thereafter, the surfaces 4f of the upper and lower attachment parts 434a and 434b are overlapped with the back surface 4b of the chest surface forming part 42 and attached with the upper and lower double-sided tapes 435a and 435b, thereby forming the shoulder parts 11.

[0125] With the above configuration, male torso 1 can form curved surfaces using sheet-shaped exterior sheet 4, eliminating unnecessary corners on the surface and allowing for highly reproducible body lines that closely resemble the actual male physique. Male torso 1 can be made stronger by providing support 3, which corresponds to the overall framework. Male torso 1 can be formed using a cardboard member that forms support 3 and a single exterior sheet 4, allowing it to be formed using a small number of parts. The male torso 1 is configured such that the length of the chest core 3b in the width direction X is longer than the length of the abdominal core 3a, thereby clearly distinguishing the male's chest and abdomen and more accurately representing the shape of the male upper body. The male torso 1 has a pair of shoulder surface forming parts 43, 43, where the surfaces 4f of the upper and lower attachment parts 434a and 434b are overlapped and attached to the back surface 4b of the chest surface forming part 42 along the upper shoulder cutouts 431a and lower shoulder cutouts 431b, forming the shoulders 11. Furthermore, the chest surface forming part 42 of the male torso 1 protrudes outward between the upper end 42a and the continuous part 4a along the front end surface 3k of the chest core part 3b. This configuration allows the shoulders 11 to be formed with a raised central portion in the depth direction. Furthermore, because the chest surface forming part 42 is shaped to bulge forward, it creates a shape that corresponds to a male chest, allowing for highly reproducible representation of the characteristics of a male chest. As a result, it is possible to create a shape in which the center of the shoulder is raised, the shoulder is stretched in the depth direction, and the side of the body from the armpit to the chest and abdomen is stretched in a downward, narrowing direction, so that the characteristics of the line from the shoulder to the arm on the side of a man's body can be reproduced with high reproducibility. The male torso 1 can highly reproducibly represent the characteristic shape of a man's abdomen by covering the front and sides of the abdominal core 3a with the abdominal surface forming portion 41. Furthermore, the area that is primarily visible when the torso is on display can be expressed with a curved surface, improving the aesthetic appearance of the torso. Furthermore, by arranging the curved abdominal surface forming portion 41 in front of the abdominal core 3a, the male torso 1 can highly reproducibly represent the characteristic shape of the abdomen, which has a flat, smooth line from the chest to the abdomen. As described above, the male torso 1 can accurately express the characteristics of a male physique by the method of attaching the exterior sheet 4 to the support body 3 and the shapes of the support body 3 and the exterior sheet 4 when molding the torso.

[0126] With the above configuration, the exterior sheet 4 of the male torso 1 is formed from PP paper, which is lightweight and has excellent strength and tear resistance, thereby increasing the strength against external forces such as those caused by the weight of the attached clothing, as well as against external forces acting in a direction that would tear the exterior sheet 4. Because the exterior sheet 4 can be easily curved by applying force and bending it, the male torso 1 can easily express a body shape that is close to that of a real man by covering the front portion 3e of the support body 3 with the exterior sheet 4 along the support body 3. By combining the support body 3, which serves as a framework made of cardboard, with the exterior sheet 4 made of PP paper, the male torso 1 can be manufactured at a lower cost than the resin torsos that are commonly used in the past.

[0127] In the male torso 1, a positioning cutout 319b in the form of a cross is formed in the base portion 315b of the first main body part 31 of the support body 3. In the male torso 1, a positioning portion 319a is printed on the first main body part 31, and a positioning portion 337a is printed on the third main body part 33. In the male torso 1, a positioning cutout 413 in the form of a triangular cutout is formed in the center of the lower end 41a of the first abdominal surface attachment tab 412a of the exterior sheet 4, and cutouts 433, 433 are formed in the pair of shoulder surface forming portions 43, 43, respectively.

[0128] With the above configuration, the male torso 1 can easily attach the support body 3 and the exterior sheet 4 to each other by aligning the position of the positioning cutout 319b with the position of the notch 413, without misalignment of the attachment positions. In the male torso 1, the support body 3 and the outer sheet 4 are bonded together along the positioning portions 319a, 337a, so that the position where the support body 3 and the outer sheet 4 are bonded together is clear, and the male torso 1 can be easily attached in the correct position. In the male torso 1, the cutouts 433 allow the chest forming section 42 and the shoulder forming section 43 to be bonded together at accurate positions. As described above, male torso 1 allows accurate and easy joining of each part, resulting in a high-quality finished product that does not depend on the assembly worker. Furthermore, male torso 1 has positioning notch 319b, notch 413, and slit 433, which are located at the front and easily visible from the outside when the torso is on display, formed in an inconspicuous configuration, making them less noticeable and improving the aesthetic appearance of the torso. Furthermore, the torso can be molded according to simple slits, notches, and slits.

[0129] In the male torso 1, the outer sheet 4 has a first abdominal attachment tab 412a formed at the lower end of the abdominal surface forming portion 41 as an attachment position to the support body 3, multiple second abdominal surface attachment tabs 412b formed at the left and right ends of the abdominal surface forming portion 41, and a chest surface attachment tab 422a formed at the upper end of the chest surface forming portion 42.

[0130] With the above configuration, the male torso 1 clearly defines the attachment position of the support body 3 and the exterior sheet 4, and therefore the male torso 1 can be easily assembled into a predetermined shape without misalignment of the attachment position of the exterior sheet 4. Because the attachment position of the exterior sheet 4 is accurate, the male torso 1 can be assembled into a shape with superior aesthetics.

[0131] The male torso 1 is placed upright on the installation surface F by a base 3d formed by bending the second forming portion 31b of the first main body part 31 of the support body 3, and is stably disposed on the installation surface F. With the above configuration, the male torso 1 is stably supported in an upright state on the installation surface F. Because the base 3d can be formed by bending the second forming portion 31b, it can be easily formed using only the first main body part 31 without adding any new parts.

[0132] The male torso 1 has a neck portion 1a formed by inserting the neck component 5 into a neck insertion groove 3j formed by bending the third formed portion 33c of the third main body part 33 at a substantially right angle along a bending line 333h toward the neck insertion hole 3i. With the above configuration, the male torso 1 can represent a male neck, thereby expressing the male physique in more detail. By having the neck portion 1a, the male torso 1 can prevent the position of the clothing from shifting when the male torso 1 is dressed in clothing, and can hold the clothing in the desired position.

[0133] Male torso 1 is formed from main body parts made of cardboard and sheet-shaped exterior sheet 4, making it lightweight and easy to transport and install. Male torso 1 can be formed into support body 3 simply by inserting each main body part into its corresponding insertion section and folding it along its corresponding folding line. Furthermore, exterior sheet 4 is attached to support body 3 by adhering double-sided tape 414, 424. Therefore, male torso 1 can be formed without the need for other tools such as adhesives.

[0134] Male torso 1 has positioning portions, first step instruction portions, second step instruction portions, and marks formed by printing in positions that are not visible from the outside when in use, such as on back 3f of support 3. With the above configuration, male torso 1 does not impair the appearance when in use because the positioning portions, first step instruction portions, second step instruction portions, and marks are not visible from the outside when in use.

[0135] The male torso 1 is configured so that the back 3f and base 3d, which are not visible when in use, are not covered with an exterior sheet 4, so the structure for covering these areas can be omitted, reducing the number of parts and making it easy to assemble.

[0136] The male torso 1 has two pairs of abdominal surface attachment tabs 412b, 412b attached to the back 3f, allowing the exterior sheet 4 to be attached directly to the back 3f, thereby enabling smooth lines to be created from the chest and abdomen to the chest, abdominal, and waist regions. The male torso 1 has an arrangement in which the abdominal surface forming portion 41 is wrapped around the chest and abdominal regions, allowing for highly reproducible representation of the characteristics of a man's side body shape, such as a bulging abdomen.

[0137] The male torso 1 has forward protrusions 3g and rearward protrusions 3h formed at the front and rear of the bottom surface 315a in the depth direction, so that the contact area with the installation surface F can be expanded in one direction, and therefore the structure above the base 3d can be supported more stably without reducing the contact area with the installation surface F in all directions.

[0138] <Second embodiment> A torso 2 according to a second embodiment of the present invention will be described below with reference to Figs. 11 to 21. The torso 2 is a torso that represents a female body type. Hereinafter, the torso 2 in this embodiment will be referred to as a "female torso 2." In this embodiment, components corresponding to those in the male torso 1 described above will be assigned the same reference numerals, and their description will be omitted.

[0139] 11 and 12, similar to the male torso 1, the female torso 2 includes a support body 3 formed by assembling a plurality of main body parts made of cardboard, and a sheet-like exterior sheet 4, and is formed by attaching the exterior sheet 4 to the support body 3. The support body 3 is formed by folding a first main body part 31, a second main body part 32, a third main body part 33, and a fourth main body part 34 shown in FIGS. 13 to 16 at predetermined positions and assembling the parts 31, 32, 33, and 34.

[0140] 13, the left first insertion portion 311a and the right first insertion portion 311d formed in the first forming portion 31a of the first main body part 31 are formed at the left end portion 31c and the right end portion 31d, respectively, at positions spaced apart in the downward direction B2 from the upper end 31e. The left second insertion portion 311b and the right second insertion portion 311e are formed spaced apart in the downward direction B2 from the left first insertion portion 311a and the right first insertion portion 311d, respectively. The left third insertion portion 311c and the right third insertion portion 311f are formed spaced apart in the downward direction B2 from the left second insertion portion 311b and the right second insertion portion 311e, respectively. The distance in the up-down direction B between the left second insertion portion 311b and the left third insertion portion 311c and between the right second insertion portion 311e and the right third insertion portion 311f are both longer than the distance in the up-down direction B between the left first insertion portion 311a and the left second insertion portion 311b and between the right first insertion portion 311d and the right second insertion portion 311e. The insertion portions formed on the left end portion 31c and the insertion portions formed on the right end portion 31d are arranged symmetrically with dimensions that approximately coincide with each other about the center line in the left-right direction A.

[0141] A notched chamfered portion 312i is formed on the upper side of the left end of the left first insertion portion 311a. At the left end of the left first insertion portion 311a, the upper open end is located closer to the right in the A1 direction than the lower open end. The right first insertion portion 311d is formed with a chamfered portion 312j that is symmetrical to the chamfered portion 312i with respect to the center line in the left-right direction A. At the right end of the right second insertion portion 311e, the upper open end is located closer to the left in the A2 direction than the lower open end.

[0142] The left end of the left second insertion portion 311b is formed with a chamfered portion 312k that is cut out in both the up and down directions, widening the open end of the left end of the left second insertion portion 311b. The right second insertion portion 311e is formed with a chamfered portion 312m that is symmetrical to the chamfered portion 312k about the center line in the left-right direction A, widening the open end of the right end of the right second insertion portion 311e.

[0143] The first forming portion 31a has an inclined portion 312n that slopes downward from the intersection 317e toward the left end 31h and an inclined portion 312o that slopes downward from the intersection 317f toward the right end 31n. The first forming portion 31a has an inclined side 31i formed between the left end 31h and the chamfered portion 312i. The first forming portion 31a has an inclined side 31i formed between the right end 31n and the chamfered portion 312j. The upper portion of the first forming portion 31a is formed with a left sixth insertion portion 311j that extends from the left end 31h in the downward direction B2 and a right sixth insertion portion 311k that extends from the right end 31n in the downward direction B2. The left sixth insertion portion 311j and the right sixth insertion portion 311k are symmetrically disposed with dimensions that substantially coincide with the center line in the left-right direction A.

[0144] The left end 31c of the first forming portion 31a has a protruding portion 31u that protrudes in an arc shape toward the left direction A2 at a position between the left first insertion portion 311a and the left second insertion portion 311b and closer to the left first insertion portion 311a. The left end 31c is inclined in a direction such that the length in the left-right direction A narrows from the end of the protruding portion 31u on the left second insertion portion 311b side toward the left end 31h of the lower end 31f.

[0145] The right end 31d of the first forming portion 31a has a protrusion 31v that protrudes in an arc shape toward the right direction A1 at a position between the right first insertion portion 311d and the right second insertion portion 311e and closer to the right first insertion portion 311d. The right end 31d is inclined in a direction narrowing in the left-right direction A from the end of the protrusion 31v on the right second insertion portion 311e side toward the right end 31n of the lower end 31f. The inclination angle of the left end 31c and the right end 31d with respect to the central axis in the left-right direction A is, for example, between 5° and 11°, both inclusive, which is larger than the angle of the male torso 1.

[0146] The distance in the left-right direction A between the left third insertion portion 311c and the right third insertion portion 311f is shorter than that of the male torso 1 due to the inclination angles of the left end portion 31c and the right end portion 31d. Similarly, the insertion lengths of the left third insertion portion 311c and the right third insertion portion 311f are also shorter than the insertion lengths of the insertion portions of the male torso 1.

[0147] The left protruding portion 318a and the outer portions 318d, 318d of the right protruding portion 318c of the insertion portion 315c of the second forming portion 31b are each formed in an arc shape protruding in the left-right direction A.

[0148] The first main body part 31 does not have a positioning portion 319a printed on the first forming portion 31a. The first main body part 31 does not have a positioning notch 319b formed in the second forming portion 31b. The first main body part 31 does not have a second procedure instruction portion 319d printed on it. The first main body part 31 has first procedure instruction portions 319c printed on one surface 319 of the first main body part 31 at positions adjacent to the left sixth insertion portion 311j and the right sixth insertion portion 311k. The mark 319e printed on the center portion 314c is positioned below the fourth insertion portion 311g.

[0149] 14, outer portions 321d, 321d of left protruding portion 321a and right protruding portion 321c of second main body part 32 are each formed in an arc shape protruding in left-right direction A. The insertion lengths of left insertion portion 322a and right insertion portion 322b of second main body part 32 are formed shorter than the insertion lengths of the insertion portions of male torso 1 in accordance with the length between left second insertion portion 311b and right second insertion portion 311e.

[0150] As shown in FIG. 15, the third main body part 33 has a first forming portion 33a, a second forming portion 33b, a third forming portion 33c, and a fourth forming portion 33d.

[0151] Similar to the second main body part 32, the first forming part 33a has outer portions 331d, 331d of the left protruding part 331a and the right protruding part 331c each formed in an arc shape protruding in the left-right direction A. The insertion lengths of the left inserting part 332a and the right inserting part 332b of the first forming part 33a are formed shorter than the insertion lengths of the inserting parts of the male torso 1 in accordance with the length between the left first inserting part 311a and the right first inserting part 311d.

[0152] The second forming portion 33b does not have bending lines 333b and 333c. The second forming portion 33b has a triangular protrusion 33m between the bending lines 333a and 333d and 333e, with both ends in the left-right direction A protruding outward. The triangular apexes 33n and 33n on both sides of the protrusion 33m in the left-right direction A are chamfered. The length of the protrusion 33m in the up-down direction B is approximately equal to the length from the left end 31h of the first main body part 31 to the left first insertion portion 311a and the length from the right end 31n to the right first insertion portion 311d. The distance in the up-down direction B between the bending lines 333d and 333e and the bending lines 333f and 333g is approximately equal to the length of the inclined portions 312n and 312o.

[0153] The cutouts 335 provided in the third forming portion 33c are formed to extend upward to between the folding lines 333f, 333g and the tops 33n, 33n.

[0154] The first back portion 336a of the fourth forming portion 33d is formed between the connecting portions 33g, 33h and the second back portion 336b in a trapezoidal shape with both ends in the left-right direction A protruding outward. Apices 336f, 336f of the trapezoidal shape at both ends in the left-right direction A of the first back portion 336a are formed closer to the second back portion 336b. The second back portion 336b of the fourth forming portion 33d is inclined in a direction in which its length in the left-right direction A narrows from the connecting portion with the first back portion 336a toward the insertion portion 336c. The second back portion 336b is formed so that the length of its sides in the left-right direction A is longer than the length of the corresponding sides of the male torso 1, and the length of its sides in the up-down direction B is shorter than the length of the corresponding sides of the male torso 1.

[0155] The length in the up-down direction B between the bending lines 333d, 333e and the bending lines 333g, 333h is approximately equal to the length of the inclined portions 312n, 312o at the upper end 31e of the first main body part 31. The maximum length in the left-right direction A of the insertion portion 336c is approximately equal to the length in the left-right direction A of the fourth insertion portion 311g of the first main body part 31.

[0156] Positioning portions 337a, 337a printed on first spine 336a of fourth forming portion 33d extend slightly from the vicinity of the intersection of folding line 333f and notch 335 and from the vicinity of the intersection of folding line 333g and notch 335 toward mark 337d printed on first spine 336a, and are printed in a shape that extends from the leading ends toward apexes 336f, 336f on both the left and right ends. Positioning portion 337a and second procedure instruction portion 337c are not printed on second spine 336b.

[0157] As shown in FIG. 16 , the fourth main body part 34 has a left protrusion 341a, a central portion 341b, and a right protrusion 341c. The fourth main body part 34 is formed symmetrically about the center line in the left-right direction A. The left protrusion 341a includes a protrusion 342a that protrudes in a generally triangular shape in the left direction A2 and a generally rectangular protrusion 343a that extends downward in the direction B2 from the lower end of the protrusion 342a. The right protrusion 341c includes a protrusion 342b that protrudes in a generally triangular shape in the right direction A1 and a generally rectangular protrusion 343b that extends downward in the direction B2 from the lower end of the protrusion 342b. The apexes 344a and 344b of the protrusions 342a and 342b in the left-right direction A are chamfered. The apexes of the protrusions 342a and 342b in the up-down direction B are formed with linear portions 345a and 345b.

[0158] The central portion 341b is formed in a substantially rectangular shape, and an upper portion 341d of the central portion 341b is connected to the middle portions of the left protruding portion 341a and the right protruding portion 341c in the up-down direction B. The heights of the lower ends of the central portion 341b, the protrusions 343a, and the protrusions 343b are substantially the same.

[0159] The fourth main body part 34 includes a left insertion portion 346a that opens downward between the lower end of the protrusion 343a and the lower end of the central portion 341b, and a right insertion portion 346b that opens downward between the lower end of the central portion 341b and the lower end of the protrusion 343b. The lengths of the left insertion portion 346a and the right insertion portion 346b are approximately the same. The open ends of the left insertion portion 346a and the right insertion portion 346b are chamfered and widened in the left-right direction A.

[0160] On one side 347 of the fourth main body part 34, first procedure instruction portions 347a corresponding to first procedure instruction portion 319c are printed in positions adjacent to left insertion portion 346a and right insertion portion 346b, respectively, and a mark 347b indicating that it is the fourth main body part 34 is printed in the center of central portion 341b. First procedure instruction portion 347a and mark 347b are printed in the same design as the first procedure instruction portions and indicating portions of each main body part. One side 347 is the printed side.

[0161] 17 to 19, a method for assembling the support body 3 will be described below. First, in the same manner as for the male torso 1, the first main body part 31 is bent and the second main body part 32 is attached, the first forming part 31a is made to stand vertically, and the second forming part 31b is bent and inserted into the first forming part 31a, thereby forming the base 3d.

[0162] After forming the base 3d, the left insertion portion 346a and the right insertion portion 346b of the fourth body part 34 are inserted into the right sixth insertion portion 311k and the left sixth insertion portion 311j of the first body part 31 with one surface 347 facing the inclined side 31i. The fourth body part 34 is inserted to a depth where the inner ends of the insertion portions abut, similar to the second body part 32 and the insertion portion 315c. The fourth body part 34 is positioned between the chamfered portions 312i, 312m and the fourth forming portion 33d of the third body part 33, closer to the fourth forming portion 33d in a side view.

[0163] After the fourth body part 34 is inserted into the first body part 31, the third body part 33 is folded in a mountain fold direction along the folding line 333a. After the third body part 33 is folded along the folding line 333a, the protruding portions 33m are placed in contact with the inclined sides 31i, 31i.

[0164] After the third main body part 33 is bent along the bending line 333a, the third main body part 33 is bent along the bending lines 333d and 333e located on the left end 31h and the right end 31n, and the second forming portion 33b located between the bending lines 333d and 333e and the bending lines 333f and 333g is positioned on the inclined portions 312n and 312o.

[0165] After folding the third main body part 33 along the folding lines 333d and 333e, the third main body part 33 is folded along the folding lines 333f and 333g in the same manner as the male torso 1. The fourth forming portion 33d of the third main body part 33 is folded downward in the Z direction by approximately 90 degrees from the folding lines 333f and 333g at a position where the folding lines 333f and 333g contact the upper end 31e, and is positioned so as to abut on the central portion 314c. After the fourth forming portion 33d is positioned on the central portion 314c, the fourth forming portion 33d is folded along the folding line 333i, and the insertion portion 336c is inserted into the fourth insertion portion 311g.

[0166] Similar to the male torso 1, the third forming portion 33c is cut out from the notch 335 by bending the third main body part 33 along the bending lines 333d and 333e, and is arranged to extend upward at approximately 90 degrees from the upper end 31e. The third forming portion 33c is folded along the bending line 333g, and is arranged to extend upward while standing at approximately 90 degrees from the upper end 31e.

[0167] In this way, the support body 3 of the female torso 2 is formed. The front part of the abdominal core 3a of the support body 3 protrudes forward in the front-to-back direction Y at the upper end of the abdominal core 3a due to the protruding parts 31u, 31v of the first forming part 31a. The front part of the abdominal core 3a is inclined in a direction narrowing in length in the front-to-back direction Y from the protruding parts 31u, 31v, which are the upper end of the abdominal core 3a, towards the lower end of the abdominal core 3a due to the narrowing slope of the lower ends 31f of the left end 31c and right end 31d.

[0168] The front portion of the chest core 3b of the support body 3 is formed by the second forming portion 33b of the third main body part 33, which is arranged above the intersection 317e of the first main body part 31 and extends from the left first insertion portion 311a to the intersection 317f and from the right first insertion portion 311d. The back portion of the chest core 3b is formed by the first spine 336a and the second spine 336b of the third main body part 33.

[0169] The pair of shoulder cores 3c, 3c of the support body 3 are formed so that the tops 344a, 344b of the fourth main body part 34 protrude outward in the width direction X further than the tops 33n, 33n of the protruding portion 33m of the third main body part 33 and the tops 336f, 336f of the first spine 336a. The support body 3 is formed so that the inclination angles of the upper sides 342c, 342d of the protruding portions 342a, 342b of the fourth main body part 34 are smaller than the inclination angles of the upper triangular side of the protruding portion 33m of the third main body part 33 and the inclination angle of the upper side of the trapezoidal shape, which correspond to the inclination angle of the protruding portion above the first spine 336a.

[0170] The pair of shoulder cores 3c, 3c of the support body 3 are formed by a protruding portion 33m, a first back portion 336a, and protruding portions 342a, 342b. The peaks 33n, 33n, peaks 336f, 336f, and peaks 344a, 344b of the pair of shoulder cores 3c, 3c are all located approximately in the middle of the chest core 3b in the height direction Z. In addition, the protruding ends of the pair of shoulder cores 3c, 3c become the peaks 344a, 344b of the fourth main body part 34.

[0171] Similar to the male torso 1, the base 3d of the support body 3 is placed on the installation surface F, and the support body 3 is raised to support a component located above the base 3d. Similar to the male torso 1, the base 3d is formed with a forward protruding portion 3g that protrudes toward the front 3e in the front-to-back direction Y, and a rearward protruding portion 3h that protrudes toward the back 3f in the front-to-back direction Y. The contact area of ​​the bottom surface 315a of the base 3d with the installation surface F may be changed depending on the size of the support body 3, as long as the base 3d can support the support body 3 in an upright position.

[0172] The support body 3 is formed such that the protruding length in the width direction X of the insertion portion 315c is longer than the length of the corresponding portion of the male torso 1 due to the arc shape of the outer portions 318d, 318d of the first main body part 31. The support body 3 is formed such that the protruding length in the width direction X of the insertion portion 315c is longer than the length of the corresponding portion of the male torso 1 due to the arc shape of the outer portions 321d, 321d of the second main body part 32. The support body 3 is formed such that the protruding length in the width direction X of the first forming portion 33a is longer than the length of the corresponding portion of the male torso 1 due to the arc shape of the outer portions 331d, 331d of the third main body part 33.

[0173] The front part of the chest core 3b is formed smoothly by the shape of the inclined sides 31i, 31i and inclined portions 312n, 312o of the first forming part 31a, and the second forming part 33b is arranged above the inclined sides 31i, 31i and inclined portions 312n, 312o.

[0174] As described above, the support body 3 is formed by assembling multiple main body parts made of corrugated cardboard by folding them along the folding lines and inserting the inserts into each other, without the need for adhesives or other connectors. Despite its simple structure, the support body 3 expresses the characteristics of a woman's figure from the shoulders to the abdomen.

[0175] As shown in Figure 20, the exterior sheet 4, like the male torso 1, has an abdominal surface forming portion 41, a chest surface forming portion 42, and a pair of shoulder surface forming portions 43, 43, and is made of sheet-shaped PP paper.

[0176] The abdominal surface forming portion 41 has a covering portion 411 and an abdominal surface attachment tab 412c. The covering portion 411 is formed in a generally rectangular shape that is long in the left-right direction A. The left end 411b and the right end 411c of the covering portion 411 are inclined such that the length of the covering portion 411 in the left-right direction A decreases from the upper end 411e to the lower end 411a.

[0177] The covering portion 411 has cut portions 415a and 415b formed at the upper and lower portions close to the left end 411b of the left portion 41b. Hereinafter, the cut portions 415a and 415b will be referred to as notches 415a and 415b. The notches 415a and 415b are formed in a hook shape that roughly matches the shape of the vertical corners 41e and 41e of the portion of the belly-surface-attaching tab 412c that continues to the covering portion 411.

[0178] The ventral surface attachment tab 412c is formed to protrude in the right direction A1 from the center of the right end 411c of the covering portion 411. The ventral surface attachment tab 412c is formed in a substantially rectangular shape. A double-sided tape 414 is attached to the ventral surface attachment tab 412c on one surface 4b of the exterior sheet 4.

[0179] The chest surface forming portion 42 comprises a lower chest surface forming portion 42b that is continuous with the upper end of the abdominal surface forming portion 41, and an upper chest surface forming portion 42c that is continuous with the upper end of the lower chest surface forming portion 42b and is continuous with a pair of shoulder surface forming portions 43, 43 at its left and right ends.

[0180] The lower chest surface forming portion 42b has a covering portion 425a and a first chest surface attachment tab 422b. The covering portion 411 is formed in a generally rectangular shape that is elongated in the left-right direction. The abdominal surface forming portion 41 and the lower chest surface forming portion 42b are continuous at the center portion 4h, and the left portion 41b of the abdominal surface forming portion 41 is spaced apart from the left portion 42d of the lower chest surface forming portion 42b. Similarly, the right portion 41c of the abdominal surface forming portion 41 is spaced apart from the right portion 42e of the lower chest surface forming portion 42b.

[0181] The lower chest surface forming part 42b has a first chest surface attachment tab 422b. The first chest surface attachment tab 422b is formed by protruding rightward from the center of the right end 425b of the covering part 425a. The first chest surface attachment tab 422b is formed in a substantially rectangular shape. Double-sided tape 424 is attached to the first chest surface attachment tab 422b on one surface 4b of the exterior sheet 4.

[0182] The covering part 425a has cut parts 426a and 426b formed at the top and bottom of the left end 425c of the left part 42d. Hereinafter, the cut parts 426a and 426b will be referred to as notches 426a and 426b. Similar to the notches 415a and 415b, the notches 426a and 426b are formed in a hook shape that roughly matches the shape of the vertical corners 42f and 42f of the connecting part between the covering part 425 and the first chest surface attachment tab 422b.

[0183] The lower chest surface forming portion 42b has a left lower protrusion 42g that overlaps the left portion 42d from the other side 4f of the left portion 41b and protrudes downward. The lower chest surface forming portion 42b has a right lower protrusion 42h that overlaps the right portion 42e from the other side 4f of the right portion 41c and protrudes downward. The left lower protrusion 42g and the right lower protrusion 42h are curved. The upper end of the lower chest surface forming portion 42b is curved and protrudes upward.

[0184] The left and right portions 42d and 42e of the lower chest surface forming portion 42b are formed so as to protrude leftward and rightward, respectively, from the left and right portions 41b and 41c of the abdominal surface forming portion 41.

[0185] The upper chest surface forming part 42c has a covering part 425a and a pair of second chest surface attachment tabs 422c, 422c. The pair of second chest surface attachment tabs 422c, 422c are formed so as to sandwich the neck insertion part 423 between both ends of the upper end 42a in the left-right direction A, and to protrude upward at an angle of 13° to 19° with respect to the left-right direction A of the outer covering sheet 4.

[0186] The pair of second chest surface attachment tabs 422c, 422c has a double-sided tape 424 attached to one surface 4b. The length between the second chest surface attachment tab 422c and the neck insertion part 423 is approximately the same as the length of the folding lines 333f, 333g of the third main body part 33 in the left-right direction.

[0187] The pair of shoulder surface forming parts 43, 43 have a common configuration. The following describes the configuration of one of the shoulder surface forming parts 43. The shoulder surface forming part 43 has an arc-shaped shoulder sleeve part 437 that protrudes outward in the left-right direction A from the opposing end 422d of the adjacent second chest surface attachment tab 422c toward the outer tip part 436a of the shoulder surface forming part 43.

[0188] The outer edge of the shoulder surface forming portion 43 extends from the outer tip 436a to an inner inner end 436b located on the upper chest surface forming portion 42c side in a direction approximately perpendicular to the tangent of the arc-shaped shoulder / sleeve portion 437 passing through the outer tip 436a, and a lower notch 431c separates the inner inner end 436b from the upper chest surface forming portion 42c. The lower notch 431c is formed in a straight line from the inner inner end 436b to near the center of the boundary between the upper chest surface forming portion 42c and the shoulder surface forming portion 43.

[0189] A double-sided tape 435c is attached to the shoulder surface forming portion 43 at a position close to the inner inner end portion 436b on the other surface 4f side. The shoulder surface forming portion 43 does not have a cut portion 433 formed therein.

[0190] The upper chest surface forming portion 42c has hook-shaped cut portions 426c and 426d formed at positions close to the lower end of the lower cut portion 431c in the left-right direction, and opening toward the adjacent shoulder surface forming portion 43. Hereinafter, the cut portions 426c and 426d will be referred to as cut portions 426c and 426d.

[0191] 11 and 12 and 20 and 21, a method for attaching the exterior sheet 4 to the support body 3 of the female torso 2 will be described. The exterior sheet 4 is attached to the support body 3 in accordance with the numbers in the second procedure instruction section 337c printed on one surface 337 of the third main body part 33.

[0192] First, the exterior sheet 4 is placed on the front part 3e of the support body 3 in the orientation shown in Figure 20. The pair of second chest attachment tabs 422c, 422c of the exterior sheet 4 are placed on the back part 3f side of the support body 3, and the edges of the second chest attachment tabs 422c are aligned with the pair of positioning portions 337a, 337a printed on the left and right ends of the first back part 336a and attached with double-sided tape 424. The pair of second chest attachment tabs 422c, 422c are attached to the back surface of the chest core part 3b of the support body 3. The exterior sheet 4 is attached to the support body 3 by the above procedure. One surface 4b of the exterior sheet 4 is the back surface 4b, and the other surface 4f is the front surface 4f.

[0193] After attaching the pair of second chest surface attachment tabs 422c, 422c, the left and right portions 41b, 41c of the abdominal surface forming portion 41 are placed on the back portion 3f side of the support body 3, and the corners 41e, 41e are aligned with the notches 415a, 415b. In this state, the abdominal surface attachment tab 412c is attached to the front surface 4f side of the left portion 41b with double-sided tape 414, and the abdominal surface forming portion 41 is formed into a cylindrical shape around the outer periphery of the abdominal core portion 3a.

[0194] After bonding the left and right parts of the abdominal surface forming part 41 together, the left part 42d and right part 42e of the lower chest surface forming part 42b are placed on the back part 3f side of the support body 3, and the corners 42f, 42f are aligned with the notches 426a, 426b. In this state, the first chest surface attachment tab 422b is attached to the front surface 4f side of the left part 42d with double-sided tape 424, and the lower chest surface forming part 42b is formed into a cylindrical shape around the outer periphery of the abdominal core 3a.

[0195] When the second chest surface attachment tabs 422c, 422c are attached to the first back portion 336a, the left lower protrusion 42g and the right lower protrusion 42h of the lower chest surface forming portion 42b are positioned above the lower end of the first back portion 336a. The left and right portions 42d, 42e of the lower chest surface forming portion 42b are attached to the back portion 3f near the boundary between the second back portion 336b and the central portion 314c, so the left and right portions 42d, 42e are positioned at a downward incline on both sides of the support body 3. Because the left and right portions 42d, 42e have the above-described configuration, the rightward A1 end of the lower chest surface forming portion 42b, which is continuous with the central portion 4h of the left lower protrusion 42g in FIG. 20, and the leftward A2 end of the lower chest surface forming portion 42b, which is continuous with the central portion 4h of the right lower protrusion 42h in FIG. 20, protrude forward, forming protrusions 4i, 4j. Since a portion of the upper end of the abdominal surface forming portion 41 overlaps with the left lower protrusion 42g and the right lower protrusion 42h when unfolded, the protrusions 4i and 4j are formed without creating any gaps at the boundary between the abdominal surface forming portion 41 and the lower thoracic surface forming portion 42b.

[0196] After bonding the left and right sections of the lower chest surface forming section 42b together, the lower cutout 431c of the shoulder surface forming section 43 is moved toward the upper chest surface forming section 42c on the surface 4f. As the shoulder surface forming section 43 moves toward the upper chest surface forming section 42c, its center protrudes toward the surface 4f, deforming to fit the curved surface of the upper chest surface forming section 42c along the chest core 3b. The shoulder surface forming section 43 is aligned with the corner of the adjacent cutout 426c, aligning the lower cutout 431c with the cutout 426c. The back surface 4b of the shoulder surface forming section 43 is then overlapped with the surface 4f of the upper chest surface forming section 42c, and attached to the upper chest surface forming section 42c with double-sided tape 435c. The above procedure is repeated for both shoulder surface forming sections 43, and the pair of shoulder surface forming sections 43, 43 are attached to the upper chest surface forming section 42c.

[0197] By the above procedure, the surface 4f of the chest surface forming portion 42 and the back surfaces 4b of the pair of shoulder surface forming portions 43, 43 are bonded together to form the shoulder portions 11 of the female torso 2. The inclination angle of the shoulder portions 11 is larger than the angle of the corresponding portion of the male torso 1, and is inclined downward from 35° to 41° relative to the horizontal when viewed from the front.

[0198] The female torso 2, like the male torso 1, is provided with a neck component 5, and the neck component 5 is inserted into the neck insertion hole 3i by about half of the side 5b. Next, the third forming portion 33c is bent along the bending line 333h toward the neck insertion hole 3i to form the neck insertion groove 3j. Next, the neck component 5 is inserted into the neck insertion groove 3j until it is attached to the neck insertion groove 3j due to elastic behavior in the direction of returning the neck component 5 from the curved surface to a flat surface, thereby forming the neck 2a.

[0199] In accordance with the desired size of the neck 2a, the neck insertion hole 3i and neck insertion portion 423 of the female torso 2 are formed smaller than those of the male torso 1. In accordance with the above, the neck part 5 and neck insertion groove 3j of the female torso 2 are also formed smaller than those of the male torso 1, and the neck 2a is characterized by a narrow neck circumference.

[0200] Through the above procedure, the female torso 2 is formed and the front portion 3e of the support body 3 is covered. In the female torso 2, the left portion 41b and right portion 41c of the abdominal surface forming portion 41 of the exterior sheet 4 cover the sides of the abdominal core portion 3a of the support body 3, and the central portion 41d is positioned in front of the abdominal core portion 3a. The chest surface forming portion 42 is positioned in front of the chest core portion 3b of the support body 3. The pair of shoulder surface forming portions 43, 43 are positioned above the pair of shoulder core portions 3c, 3c of the support body 3 to form the shoulder portion 11 and cover the pair of shoulder core portions 3c, 3c.

[0201] The shoulder core 3c of the female torso 2 is formed so that the inclination angles of the upper sides 342c and 342d of the protrusions 342a and 342b are smaller than the inclination angles of the protrusion 33m and the first back portion 336a. Therefore, the tops of the shoulders 11 of the female torso 2 are formed along the protrusions 342a and 342b, and the inclination angle of the shoulders 11 is formed so as to be smaller than the inclination angles of the protrusion 33m and the first back portion 336a.

[0202] The shoulder core 3c of the female torso 2 is in contact with the upper edges 342c, 342d and straight portions 345a, 345b of the protrusions 342a, 342b of the fourth main body part 4 and the back surface 4b of the exterior sheet 4, and the protrusions 342a, 342b support the shoulder surface forming portions 43, 43.

[0203] The female torso 2 has side inclined portions 4k, 4m that slope from the rear end portions 427a, 427b of the chest surface forming portion 42 toward the protrusions 4i, 4j so that the dimensions in the left-right direction become smaller between the boundary between the lower chest surface forming portion 42b, which is the lower end of the chest surface forming portion 42, and the abdominal surface forming portion 41 and the lower ends of the shoulder surface forming portions 43, 43.

[0204] Next, the effects of the female torso 2 according to the embodiment of the present invention will be described.

[0205] The female torso 2 is formed by attaching a sheet-shaped outer sheet 4 so that it covers the front part 3e of a cardboard support body 3 having an abdominal core 3a, a chest core 3b and a pair of shoulder cores 3c, 3c.

[0206] The pair of shoulder cores 3c, 3c of the support body 3 are formed by the protruding portion 33m and first back portion 336a of the third main body part 33 and the protruding portions 342a, 342b of the fourth main body part 34, while the chest core 3b is formed by the second forming portion 33b of the third main body part 33. In the shoulder core 3c, the protruding portion 33m, the first back portion 336a, and the protruding portions 342a, 342b all have upper ends that slope downward toward the tip. The peaks 33n, 33n, peaks 336f, 336f, and peaks 344a, 344b of the pair of shoulder cores 3c, 3c are all formed to be located approximately in the vertical center of the chest core 3b.

[0207] The exterior sheet 4 has an abdominal surface forming portion 41 arranged in front of the support body 3, a chest surface forming portion 42 arranged in front of the chest core portion 3b of the support body 3, and a pair of shoulder surface forming portions 43, 43 formed to cover a pair of shoulder core portions 3c, 3c of the support body 3. The exterior sheet 4 has the abdominal surface forming portion 41 and the lower chest surface forming portion 42b bonded together at the back of the support body 3, and at the front portion 3e of the support body 3, the left end side of the left lower protrusion 42g and the right end side of the right lower protrusion 42h of the lower chest surface forming portion 42b protrude forward, forming protrusions 4i, 4j at approximately the middle of the chest surface forming portion 42 in the height direction Z. The exterior sheet 4 is attached by aligning the inner end portions 436b, 436b of the pair of shoulder surface forming portions 43, 43 with the cutout portions 426c, 426d of the chest surface forming portion 42, and attaching the back surface 4b side of the shoulder surface forming portions 43, 43 to the front surface 4f side of the upper chest surface forming portion 42c.

[0208] With the above configuration, the female torso 2, like the male torso 1, can have curved surfaces formed by the sheet-shaped exterior sheet 4, allowing it to accurately represent the lines of a body shape close to that of an actual woman, with no unnecessary corners on the surface. The strength of the female torso 2 can be increased by providing a support 3 that corresponds to the overall framework. The female torso 2 can be formed using a small number of parts, as it can be formed using a single exterior sheet 4 and a cardboard member that forms the support 3. The female torso 2 is formed with a pair of shoulder cores 3c, 3c tilted so that the tops 344a, 344b of the fourth main body part 34, which form the protruding ends of the pair of shoulder cores, are located approximately in the middle of the chest core 3b in the height direction Z, thereby allowing for highly reproducible reproduction of the characteristics of a woman's shoulders, such as a line from the shoulders to the arms sloping gently downward. The female torso 2 is located approximately in the middle of the height direction Z at the front 3e of the chest surface forming portion 42, and by forming protrusions 4i and 4j that protrude forward, it is possible to highly reproduce the characteristics of a woman's body shape from the chest to the abdomen, such as the lines and curves from the chest to the abdomen. The female torso 2 is configured such that the abdominal surface forming portion 41 and the lower chest surface forming portion 42b of the outer sheet cover the sides of the abdominal core portion 3a and both ends are attached to the back of the abdominal core portion 3a, thereby covering the front and sides of the abdominal core portion 3a and improving the reproducibility of the shape characteristics around a woman's abdomen. The female torso 2 is configured such that the back 4b side of the inner inner end 436b of the shoulder surface forming portion 43 is bonded to the front surface 4f side of the upper chest surface forming portion 42c to form the shoulder portion 11, so that the line from the shoulder to the arm slopes gently downward, and the characteristics of the shoulders of women, whose shoulders are narrower than those of men, can be reproduced with high reproducibility. As described above, the female torso 2 can accurately represent the female figure by using the shapes of the support body 3 and the exterior sheet 4 when molding the torso.

[0209] With the above configuration, the exterior sheet 4 of the female torso 2 is formed from PP paper, just like the male torso 1. Therefore, with the above configuration, the exterior sheet 4 of the female torso 2 is formed from PP paper, which is lightweight and has excellent strength and tear resistance, thereby further improving the load-bearing capacity due to the weight of the attached clothing, etc., and the burst strength of the exterior sheet 4. Because the exterior sheet 4 can be easily curved by applying force and bending it, the female torso 2 can easily express a body shape similar to that of a real woman by covering the front part 3e of the support body 3 with the exterior sheet 4 along the support body 3. By combining the support body 3, which serves as a cardboard framework, with the exterior sheet 4 made of PP paper, the female torso 2 can be manufactured at a lower cost than the resin torsos that are commonly used in the past.

[0210] The female torso 2 has a positioning portion 337a printed on the third main body part 33. The female torso 2 has cutouts 415a and 415b formed in the abdominal surface forming portion 41 of the exterior sheet 4, cutouts 426a and 426b formed in the lower chest surface forming portion 42b, and cutouts 426c and 426d formed in the upper chest surface forming portion 42c.

[0211] With the above configuration, the female torso 2 can easily attach the pair of second chest attachment tabs 422c, 422c to the left and right ends of the first back portion 336a along the positioning portion 337a in an accurate position without any misalignment. In the female torso 2, the cutouts 415a, 415b, 426a, and 426b allow the respective ends of the abdominal surface forming portion 41 and the lower chest surface forming portion 42b to be easily joined together at accurate positions. In the female torso 2, by aligning the inner inner ends 436b, 436b of the shoulder surface forming parts 43, 43 with the cutouts 426c, 426d, the shoulder surface forming parts 43, 43 can be attached to the upper chest surface forming part 42c, so that the shoulder surface forming parts 43, 43 and the chest surface forming part 42 can be attached together without any deviation in the attachment position, and the shoulders 11 can be formed accurately and easily. As described above, the female torso 2 allows accurate and easy joining of each part, resulting in a high-quality finished product regardless of the assembly worker. Furthermore, the female torso 2 has inconspicuous cutouts 426c and 426d at the front, which are easily visible from the outside when the torso is on display, and these cutouts are formed in an inconspicuous configuration, improving the aesthetic appearance of the torso. Furthermore, the torso can be molded according to the simple cutouts.

[0212] The female torso 2 has an outer sheet 4 formed with an abdominal surface attachment tab 412c protruding from the right end of the abdominal surface forming portion 41 as a position for attaching both ends of the abdominal surface forming portion 41, a first chest surface attachment tab 422b protruding from the right end of the lower chest surface forming portion 42b as a position for attaching both ends of the lower chest surface forming portion 42b, and a pair of second chest surface attachment tabs 422c, 422c at the upper end of the upper chest surface forming portion 42c as a position for attaching the support body 3 and outer sheet 4.

[0213] With the above configuration, the positions where the ends of the abdominal surface forming portion 41 and the lower chest surface forming portion 42b of the exterior sheet 4 are attached to each other and the positions where the support body 3 and the exterior sheet 4 are attached are clearly defined, so the female torso 2 can be easily assembled into a predetermined shape without misalignment of the attachment positions. Because the attachment positions of the exterior sheet 4 and the positions where the ends of the exterior sheet 4 are attached to each other are accurate, the female torso 2 can be assembled into a shape with a more aesthetically pleasing appearance.

[0214] Similar to the male torso 1, the female torso 2 is erected relative to the installation surface F and stably placed on the installation surface F by the support 3, which is provided by a base 3d formed by bending the second forming portion 31b of the first main body part 31. With the above configuration, the female torso 2 is stably supported in an erect state relative to the installation surface F. Because the base 3d can be formed by bending the second forming portion 31b, it can be easily formed using only the first main body part 31 without adding any new parts.

[0215] The exterior sheet 4 of the female torso 2 is attached to the support body 3 only by attaching the second chest attachment tabs 422c, 422c to the first back portion 336a, and the abdominal surface forming portion 41 and the lower chest surface forming portion 42b are wrapped around and positioned along the periphery of the abdominal core 3a. With this configuration, the abdominal surface forming portion 41 and the lower chest surface forming portion 42b of the female torso 2 are maintained in position along the abdominal core 3a due to friction with the abdominal core 3a, so the abdominal surface forming portion 41 and the lower chest surface forming portion 42b can be positioned without sagging.

[0216] The exterior sheet 4 of the female torso 2 has side inclined portions 4k, 4m that are inclined from the rear ends 427a, 427b of the chest surface forming portion 42 to the protrusions 4i, 4j so that the dimension in the width direction X becomes smaller between the boundary between the lower chest surface forming portion 42b and the abdominal surface forming portion 41 and the lower ends of the shoulder surface forming portions 43, 43.

[0217] With the above-described configuration, the female torso 2 can accurately represent the characteristics of a woman's side body shape, in which the lateral chest and flanks are gradually tapered downward from the armpits to the abdomen.

[0218] The support body 3 of the female torso 2 is inclined in a direction in which its length in the front-to-back direction Y decreases from the protrusions 31u, 31v, which are the upper end of the abdominal core 3a, toward the lower end of the abdominal core 3a, due to the inclination in the direction in which the left end 31c and the lower end 31f of the right end 31d of the first main body part 31 at the front of the abdominal core 3a narrows.

[0219] With the above-described configuration, the female torso 2 can be formed such that the abdominal surface forming portion 41 slopes downward without bulging between the boundary with the chest surface forming portion 42 and the lower end of the abdominal surface forming portion 41, thereby improving the reproducibility of the characteristics of a woman's body shape around the abdomen.

[0220] In the female torso 2, the protrusions 342a, 342b of the fourth main body part 34 come into contact with the shoulder surface forming portions 43, 43 of the exterior sheet 4 and serve as single-point support portions for the shoulder surface forming portions 43, 43, so that the characteristics of the female shoulder shape, which slopes gently downward from the shoulder to the arm and collarbone, can be expressed in more detail.

[0221] In the female torso 2, a portion of the abdominal surface forming portion 41 overlaps with the left lower protrusion 42g and the right lower protrusion 42h when the female torso 2 is unfolded, so that the protrusions 4i and 4j are closed at the bottom. With the above-described configuration, the female torso 2 can prevent openings from being formed below the left lower protrusion 42g and the right lower protrusion 42h, thereby preventing an impact on visibility from the outside and on the aesthetic appearance.

[0222] The female torso 2 has a neck portion 2a formed by inserting the neck component 5 into a neck insertion groove 3j formed by bending the third formed portion 33c of the third main body part 33 at a substantially right angle along a bending line 333h toward the neck insertion hole 3i. With the above configuration, the female torso 2 can represent a woman's neck, thereby representing the female body shape in more detail. By having the neck portion 2a, the female torso 2 can prevent the position of the clothing from shifting when the female torso 2 is dressed, and can hold the clothing in the desired position.

[0223] Like the male torso 1, the female torso 2 is formed from cardboard main body parts and a sheet-shaped exterior sheet 4, making it lightweight and easy to transport and install. The female torso 2 can be formed into the support body 3 simply by inserting it into each insertion section and folding it along each folding line. The exterior sheet 4 is attached to the support body 3 by affixing the double-sided tape 424 to the second chest attachment tabs 422c, 422c. Therefore, the female torso 2 can be formed without the need for other tools such as adhesives.

[0224] Like the male torso 1, the female torso 2 has the first step instruction parts, the second step instruction parts, and the marks formed in positions that are not visible from the outside during assembly, such as on the back 3f of the support body 3. With the above configuration, the female torso 2 does not impair its appearance during use because the first step instruction parts, the second step instruction parts, and the marks are not visible from the outside during use.

[0225] The female torso 2 is configured so that the back 3f and base 3d, which are not visible when in use, are not covered with an exterior sheet 4, so that the structure for covering these areas can be omitted, reducing the number of parts and making it easy to assemble.

[0226] The female torso 2 has forward protrusions 3g and rearward protrusions 3h formed at the front and rear of the bottom surface 315a in the depth direction, so that the contact area with the installation surface F can be expanded in one direction, thereby more stably supporting the structure above the base 3d without expanding the contact area with the installation surface F in all directions.

[0227] In order to express the physical characteristics of each gender using the above-mentioned male torso 1 and female torso 2, the overall shape, the shape of the main body parts such as the shape of the cut lines, and the shape of the exterior sheet 4, the number of main body parts, the assembly method of the support body 3 such as how to fold the main body parts, and the method of attaching the exterior sheet 4 to the support body 3 can be varied depending on the gender, thereby making it possible to express the physical characteristics of each gender with high reproducibility.

[0228] Although the embodiments of the male torso and female torso according to the present invention have been described above, the present invention is not limited to the above-described embodiments and can be modified as appropriate within the scope of the invention.

[0229] For example, in the above-described male torso and female torso embodiments, the first body part 31 and the third body part 33 are overlapped on the back 3f in a side view, but the support body 3 may be configured so that only one body part is placed on the back 3f. [Explanation of symbols]
