Description

  The present invention relates to a comforter having a plurality of raised portions.

  Conventionally, comforters such as duvets are known, and comforters are used by being hung on a user's body. Japanese Patent Application Laid-Open No. 11-9410 discloses a duvet provided with a front material, a lining material, and an intermediate cloth. The intermediate cloth is arranged between the outer cloth and the lining, and a narrow band-shaped gusset is provided between the intermediate cloth and the outer cloth and between the intermediate cloth and the inner cloth. This gusset partitions an internal space between the intermediate cloth and the outer fabric and an internal space between the intermediate cloth and the lining, and each of the partitioned internal spaces is filled with contents such as feathers.

  By filling the contents in each internal space in this way, a plurality of raised portions with gussets as boundaries are formed in the duvet. In the above-described duvet, a plurality of rhombus-shaped raised portions are provided on the outer material, and a plurality of rectangular-shaped raised portions are provided on the lining. A plurality of triangular ridges are provided on the outer edge of the outer material.

Japanese Patent Laid-Open No. 11-9410

  In the comforter described above, a plurality of triangular ridges are provided on the outer edge of the outer material, but a plurality of rhombus ridges are provided on the inner side of the outer edge. The lining is provided with a plurality of rectangular raised portions. Here, there is a problem in that the content of the quadrangular raised portions does not sufficiently reach the corners of the raised portions due to the large number of corners. In this way, heat does not easily escape from the corner portion of the raised portion because the contents do not reach the corner portion of the raised portion. Therefore, in the above-mentioned comforter in which the rhombic and rectangular bulges are provided inside the outer edge, heat escapes from the corners of these bulges, so there is room for improvement in terms of heat retention.

  An object of this invention is to provide the comforter with which heat retention property was improved.

  The inventors of the present invention have found that a triangular ridge has a smaller number of corners compared to a square ridge, thereby facilitating uniform distribution of contents. That is, since the number of the corner portions is smaller in the triangular bulge portion than in the quadrangular bulge portion, it is possible to reduce the number of portions where the contents are difficult to spread. Therefore, the content can be more uniformly distributed in the raised portion by reducing the portion where the content is difficult to be distributed. The present invention has been made based on such knowledge. That is, the comforter according to one aspect of the present invention has a content in each of the outer surface extending in a rectangular shape, the lining overlapped with the outer surface and extending in a rectangular shape, and the plurality of internal spaces partitioned between the outer surface and the lining. A plurality of ridges formed by being filled with an object, the outer edge of the outer material and the outer edge of the lining are stitched together, and the plurality of ridges are arranged in a triangle shape inside the outer edge The first raised portions are included, and a plurality of first raised portions are arranged along the longitudinal direction of the outer material and the lining material.

  In this comforter, a plurality of triangular first raised portions are arranged on the inner side of the outer edge and are arranged along the longitudinal direction. Therefore, by providing a plurality of first triangular ridges on the inner side of the outer edge, more ridges with fewer corner portions are provided on the inner side of the outer edge. Thus, by providing many ridges with a small number of corners on the inner side of the outer edge and filling each of the ridges with the contents, the contents can be distributed more uniformly to each ridge. Therefore, it is possible to make it difficult for heat to escape from each raised portion, and thus it is possible to improve the heat retaining property of the comforter.

  In addition, the plurality of raised portions include a second raised portion having an obtuse triangular shape disposed at least at one end in the longitudinal direction, and the position of the longest side of the second raised portion coincides with the position of the outer edge. Good. In this case, since the longest side of the second raised portion is located at at least one end in the longitudinal direction, the number of boundaries between the raised portions located at at least one end in the longitudinal direction can be reduced. The boundary between the raised portions is a portion where the contents are not sufficiently spread compared to other portions, so that heat easily escapes and the fit to the body is not good. Therefore, as described above, it is possible to make it difficult for heat to escape at the one end by reducing the number of boundaries between the raised portions located at at least one end in the longitudinal direction. Therefore, it is possible to improve the heat retention and improve the fit to the body.

  The plurality of raised portions include rectangular third raised portions arranged at both ends in the width direction of the front and back surfaces, and the plurality of third raised portions are arranged from one end to the other end in the longitudinal direction. May be. In this case, the rectangular third raised portions are arranged in a straight line along the longitudinal direction at both ends in the width direction, so that both ends in the width direction can be easily hung. Therefore, both ends in the width direction of the comforter are likely to hang down, so that it is possible to make it difficult for air to enter under the comforter from both ends in the width direction. As described above, since it is possible to make it difficult for air to enter under the comforter, the heat retaining property of the comforter can be further enhanced.

  According to the present invention, it is possible to improve heat retention.

  Hereinafter, embodiments of the comforter according to the present invention will be described with reference to the drawings. In the description of the drawings, the same or corresponding elements are denoted by the same reference numerals, and redundant description is omitted.

  FIG. 1 is a perspective view of a comforter 1 according to the present embodiment. FIG. 2 is a plan view schematically showing the comforter 1. The comforter 1 is a duvet, and is used by being placed on a mattress of a bed, for example. The comforter 1 has a rectangular shape as a whole. The comforter 1 includes a rectangular outer fabric 2 and a rectangular lining 3 positioned on the back side of the outer fabric 2. For example, the outer material 2 and the lining material 3 have the same shape and the same size.

  The comforters 1 are symmetrical to each other with respect to a reference line L1 that passes through the center C (when viewed from the out-of-plane direction of the outer material 2 and the lining 3) in plan view and extends in the width direction D1, and the center C And symmetric with respect to a reference line L2 extending in the longitudinal direction D2. The width direction D1 and the longitudinal direction D2 are orthogonal to each other, for example.

  As described above, the comforters 1 are symmetrical to each other with respect to the reference line L1, and therefore can be used in the same manner as when the directions in the longitudinal direction D2 are reversed but not reversed. Moreover, in the comforter 1, since the shape of the surface material 2 and the lining material 3 is mutually the same, even if it reverses front and back, it can be used similarly to the case where it does not reverse.

  The material of the outer material 2 and the lining material 3 may be cotton, polyester, rayon, lyocell or the like, and various materials can be used as the material of the outer material 2 and the lining material 3. The outer surface 2 has an outer edge 2A including two short sides 2a and two long sides 2b, and the lining 3 similarly has an outer edge 3A including short sides 3a and long sides 3b. For example, the lengths of the short sides 2a and 3a are 155 cm and the lengths of the long sides 2b and 3b are 220 cm. However, the lengths of the short sides 2a and 3a and the long sides 2b and 3b are The present invention is not limited to this and can be changed as appropriate.

  The short side 2a of the outer material 2 and the short side 3a of the lining material 3 are combined, and the outer edge 2A of the outer material 2 and the outer edge 3A of the lining material 3 are overlapped by combining the longer side 2b of the outer material 2 and the longer side 3b of the lining material 3. It is done. In this state, the outer edge 2A of the outer material 2 and the outer edge 3A of the inner material 3 are sewn together so that the outer material 2 and the inner material 3 are connected.

  As shown in FIGS. 1 to 3, the comforter 1 includes a gusset portion 4 that partitions an internal space between the outer material 2 and the lining 3. For example, the gusset part 4 is a three-dimensional quilt. The gusset portion 4 includes a first gusset portion 4a extending in the width direction D1, a second gusset portion 4b extending in the longitudinal direction D2, and a third gusset portion 4c inclined with respect to the width direction D1 and the longitudinal direction D2. Yes.

  The 1st gusset part 4a is provided in the both ends of the width direction D1 of the comforter 1, and the number of the 1st gusset part 4a is six, for example. The 2nd gusset part 4b is provided in the center and the both ends of the width direction D1 of the comforter 1, and the number of the 2nd gusset part 4b is three, for example. The third gusset portion 4c includes a portion that extends diagonally to the right and a portion that extends diagonally upward to the left in plan view, and the number of the third gusset portions 4c is, for example, eight.

  For example, the height (the length in the thickness direction D3) of the second gusset portion 4b located in the center of the width direction D1 may be higher than that of the second gusset portion 4b located on both ends of the width direction D1. In this case, the height of the 2nd gusset part 4b located in the center of the width direction D1 is 6 cm, and the height of the 2nd gusset part 4b located in the both ends of the width direction D1 can be 3 cm.

  For example, the height of the first gusset portion 4a is 3 cm. The height of the third gusset 4c gradually increases from the second gusset 4b located at both ends in the width direction D1 toward the second gusset 4b located in the center of the width direction D1 (for example, linear) To) is high. In addition, the number and height of the 1st gusset part 4a, the 2nd gusset part 4b, and the 3rd gusset part 4c are not restricted to said example, It can change suitably.

  The comforter 1 is partitioned by the gusset portion 4 arranged as described above so that the number of the internal spaces S is 24, and each of the partitioned internal spaces S is filled with the contents 6. . The contents 6 are, for example, feathers (feathers). In the comforter 1, it is possible to confine heat in the swollen feathers by using the contents 6 as feathers, and high heat retention is exhibited. Moreover, the comforter 1 forms the several protruding part 10 which swells in the thickness direction D3 which is an out-of-plane direction of the surface material 2 and the lining 3 by the filling of the content 6 to each internal space S. FIG.

  As shown in FIGS. 1 and 3, the raised portion 10 swells in a dome shape, for example, which is largely rounded and curved. The raised portion 10 includes a triangular first raised portion 11 provided on the inner side of the outer edge 2A of the outer fabric 2 and the outer edge 3A of the lining 3, and an obtuse angled triangular second raised portion provided at both ends in the longitudinal direction D2. 12 and the rectangular 3rd protruding part 13 provided in the both ends of the width direction D1 are included. The first raised portion 11, the second raised portion 12, and the third raised portion 13 are different from each other in shape.

  The 1st protruding part 11 is made into the regular triangle shape, for example. Of the three vertices of the first raised portion 11, at least two vertices are located on the inner side of the outer edges 2A and 3A. The length of one side of each first raised portion 11 is 55 cm as an example, but can be changed as appropriate. A plurality of first raised portions 11 are arranged along the longitudinal direction D2, and the number of the first raised portions 11 arranged along the longitudinal direction D2 is, for example, seven.

  Between the plurality of first raised portions 11, the second gusset portion 4b or the third gusset portion 4c is interposed. Moreover, the directions of the two first raised portions 11 adjacent to each other in the longitudinal direction D2 are opposite to each other. Thus, the efficient arrangement | positioning of the 1st protruding part 11 is implement | achieved by arrange | positioning the 1st protruding part 11 so that the direction of the two 1st protruding parts 11 adjacent to the longitudinal direction D2 may become reverse. .

  For example, two rows of the plurality of first raised portions 11 arranged along the longitudinal direction D2 are provided. Moreover, the row | line | column of the some 1st protruding part 11 located in a line along the longitudinal direction D2 is mutually symmetrical with respect to the reference line L2 extended along the longitudinal direction D2. That is, the plurality of first raised portions 11 are arranged at positions that are line-symmetric with respect to the reference line L2.

  The 2nd protruding part 12 is an obtuse angle isosceles triangle, for example. The site | part in which the 2nd protruding part 12 is provided is a site | part which a user's collar contacts. For example, the length of the equal side of the second raised portion 12 is 55 cm, and the length of the bottom side of the second raised portion 12 is 96 cm, but these lengths can be changed as appropriate.

  Each equilateral side of the second raised portion 12 coincides with one side of the first raised portion 11. Each 2nd protruding part 12 is located in the both ends side (short side 2a, 3a side) of the longitudinal direction D2 of the 1st protruding part 11. FIG. The position of the base angle of the second raised portion 12 coincides with the position of one corner of the first raised portion 11. The length of the bottom of the second raised portion 12 is twice the length of the first raised portion 11 in the width direction D1.

  The apex angle of the second raised portion 12 forming an obtuse angle is located at the center in the width direction D1, and coincides with the position where the sides of the plurality of first raised portions 11 intersect. Moreover, the base angle and base of the 2nd protruding part 12 are located in outer edge 2A, 3A (short side 2a, 3a). As described above, the bottom of the second raised portion 12 that faces the obtuse angle coincides with the outer edges 2A and 3A, so that the boundary portion (sewing line portion) of the raised portion 10 is centered in the width direction D1 at both ends in the longitudinal direction D2. Is not located. That is, the sewing line portion of the raised portion 10 does not exist in the center of the short sides 2a and 3a.

  The 3rd protruding part 13 is provided in the both ends side (long side 2b, 3b side) of the width direction D1 of the 1st protruding part 11 and the 2nd protruding part 12. FIG. Between the 3rd protruding part 13 and the 1st protruding part 11, the 2nd gusset part 4b is interposed. Each third raised portion 13 has a vertically long rectangular shape (extending in the longitudinal direction D <b> 2), and one side extending in the longitudinal direction D <b> 2 of the third raised portion 13 coincides with one side of the first raised portion 11. For example, the length of the third raised portion 13 in the longitudinal direction D2 is 55 cm, and the length of the third raised portion 13 in the width direction D1 is 29.5 cm, but these lengths can be appropriately changed. A first gusset portion 4a is interposed between the plurality of third raised portions 13.

  The plurality of third raised portions 13 are arranged from one end to the other end in the longitudinal direction D2. The number of the 3rd protruding parts 13 arrange | positioned along the longitudinal direction D2 is four, for example. The plurality of third raised portions 13 arranged along the longitudinal direction D2 are arranged at positions that are symmetrical to each other with respect to the reference line L2.

  As shown in FIGS. 4A and 5, an opening 8 into which a nozzle 7 for filling the content 6 into the internal space S is formed in one of the two short sides 2 a and 3 a. The nozzle 7 has, for example, a cylindrical shape, and the contents 6 are filled into the respective internal spaces S of the comforter 1 by ejecting the contents 6 from the nozzle 7.

  The opening 8 has a size that allows the nozzle 7 to enter. The opening 8 is formed at one end of the second gusset portion 4b extending in the longitudinal direction D2. As shown in FIGS. 4A and 4B, in the opening 8, the second gusset portion 4b has two cloth-like portions 4d, and the two cloth-like portions 4d The nozzle 7 is also passed in between. Each cloth-like portion 4d is formed with a slit 4e for allowing the nozzle 7 to pass therethrough. In the two cloth-like parts 4d, the position of the slit 4e formed in one cloth-like part 4d is different from the position of the slit 4e formed in the other cloth-like part 4d.

  Thus, since the position of the slit 4e of one cloth-like part 4d and the position of the slit 4e of the other cloth-like part 4d are different, it is easy to put the nozzle 7 in each internal space S and the smooth content The filling of the object 6 is possible. Each cloth-like portion 4d is folded as shown in FIG. 4 (b) in a state where the contents 6 are not inserted. However, in the state where the contents 6 are inserted and the internal space S is expanded, each cloth-like portion 4d rises, and each slit 4e is closed accordingly.

  Next, a manufacturing method for manufacturing the comforter 1 by filling the contents 6 in the internal spaces S with the nozzles 7 will be described with reference to FIG. In addition, the black arrow of FIG. 5 has shown a mode that the nozzle 7 is inserted in each internal space S, and the slit 4e mentioned above is provided in the base part of the black arrow.

  First, the nozzle 7 is inserted into one of the two openings 8 (for example, the right opening 8), and the nozzle 7 is pushed into the innermost portion of the second gusset portion 4b. That is, the nozzle 7 is pushed into the vicinity of the short sides 2 a and 3 a on the opposite side of the opening 8. Then, for example, the third ridge 13 located at the upper right end of FIG. 5 is filled with the content 6 from the nozzle 7, and then the left first bulge 11 is filled with the content 6 while pulling the nozzle 7 forward. . In this way, the contents 6 are sequentially filled while pulling the nozzle 7 from the back along the second gusset portion 4b. And the nozzle 7 is inserted in the opening 8 on the left side, and the content 6 is filled into the 1st protruding part 11 and the 3rd protruding part 13 like the above from the back toward this side.

  Next, the nozzle 7 is inserted into the second gusset portion 4b at the center in the width direction D1 through the opening 8 and the second raised portion 12, and the nozzle 7 is pushed to the innermost portion, and the second portion located at the innermost portion The raised portion 12 is filled with the contents 6. Then, the contents 6 are filled into the first raised portions 11 positioned on the left and right of the second gusset portion 4b while pulling the nozzle 7 from the back to the front. Then, the comforter 1 is completed by filling the second raised portion 12 located on the opening 8 side with the contents 6, removing the nozzle 7 from the opening 8, and sealing the two openings 8.

  Then, the effect of the comforter 1 which concerns on this embodiment is demonstrated. First, since the number of corner portions is smaller in the triangular first bulge portion 11 of the present embodiment than in the quadrangular bulge portion, the number of portions where the contents 6 are difficult to spread can be reduced. Therefore, the content 6 can be more uniformly distributed in each first raised portion 11 by reducing the portion where the content 6 is difficult to spread.

  In the comforter 1, the plurality of triangular first raised portions 11 are arranged on the inner side of the outer edges 2 </ b> A and 3 </ b> A and are arranged along the longitudinal direction D <b> 2. Therefore, by providing a plurality of triangular first raised portions 11 inside the outer edges 2A and 3A, more first raised portions 11 with fewer corner portions are provided on the inner side than the outer edges 2A and 3A. Will be provided.

  In this way, by providing a large number of first raised portions 11 with a small number of corners inside the outer edges 2A and 3A and filling the contents 6 in each of the first raised portions 11, each first raised portion 11 is filled with the first raised portions 11. On the other hand, since the contents 6 can be distributed uniformly, the amount of heat radiation from the corner portions of the raised portions 10 can be reduced. Therefore, it is possible to make it difficult for heat to escape from the corner portion of the raised portion 10, so that the heat retaining property of the comforter 1 can be enhanced, and the comforter 1 exhibits a higher heat retaining effect.

  In particular, in the comforter 1, the quadrangular raised portions 10 are not provided inside the outer edges 2 </ b> A and 3 </ b> A, and only the triangular first raised portions 11 are arranged. Further, only the triangular first raised portion 11 and the second raised portion 12 are arranged on the inner side of the third raised portions 13 at both ends. Therefore, the comforter 1 can exhibit a higher heat retention effect.

  The plurality of raised portions 10 include obtuse triangular second raised portions 12 arranged at both ends in the longitudinal direction D2, and the position of the longest side of the second raised portion 12 is the position of the outer edges 2A and 3A. Is consistent with Therefore, since the longest side of the 2nd protruding part 12 is located in the both ends of the longitudinal direction D2, the number of the boundary lines (sewing line part) of the protruding part 10 located in the both ends of the longitudinal direction D2 can be reduced.

  The boundary of the raised portion 10 is a portion where the content 6 is not sufficiently spread compared with other portions, so that heat easily escapes and the fit to the body is not good. Therefore, as described above, by reducing the number of borders of the raised portions 10 located at both ends in the longitudinal direction D2, it is possible to make it difficult for heat to escape at both ends, thereby improving the heat retaining property of the user's neck. And a user's fit with respect to a neck can be made favorable.

  The plurality of raised portions 10 include rectangular third raised portions 13 arranged at both ends in the width direction D1 of the outer fabric 2 and the lining 3, and the plurality of third raised portions 13 are one ends in the longitudinal direction D2. To the other end. Accordingly, the rectangular third raised portions 13 are arranged in a straight line along the longitudinal direction D2 at both ends in the width direction D1. Further, the second gusset portion 4b is arranged in a straight line from one end to the other end in the longitudinal direction D2. Therefore, both ends of the width direction D1 (parts of the third raised portion 13) can be easily hung down.

  Therefore, since both ends of the comforter 1 in the width direction D1 are likely to hang down, it is possible to make it difficult for air to enter under the comforter 1 from both ends of the width direction D1. Therefore, since it is possible to make it difficult for air to enter under the comforter 1, the heat retaining property of the comforter 1 can be further enhanced.

  Further, in the present embodiment, the example in which the height of the second gusset portion 4b located at the center in the width direction D1 is higher than that of the second gusset portion 4b located at both ends of the width direction D1 has been described. In this case, the bulk of the first raised portion 11 can be increased as compared with the bulk of the third raised portion 13. Therefore, since the quantity of the content 6 with which the center side of the width direction D1 is filled can be increased, heat retention can be improved further.

  Moreover, in the manufacturing method of the comforter 1 according to the present embodiment, the contents 6 are filled while pulling the nozzle 7 from the back to the front. In this way, by filling the contents 6 from the back to the front, the contents 6 can be smoothly filled by the nozzle 7 as compared with the case of filling from the front to the back.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to embodiment mentioned above, It changes within the range which does not change the summary described in the claim, or is applied to another thing. It may be what you did. That is, the present invention can be variously modified without departing from the gist described in the claims.

  In the above-described embodiment, the example in which two rows of the plurality of first raised portions 11 arranged in the longitudinal direction D2 are provided, but the number of rows can be changed as appropriate. For example, as shown in the comforter 21 of FIG. 6, the rows of the plurality of first raised portions 11 arranged in the longitudinal direction D2 may be increased. In the comforter 21, seven rows of the first raised portions 11 are arranged in four rows. Moreover, the row of the plurality of first raised portions 11 arranged in the longitudinal direction D2 may be only one row.

  In the above-described embodiment, the comforter 1 in which the number of the internal spaces S and the number of the raised portions 10 is 24 has been described. However, the number of the internal spaces and the raised portions is not limited to 24 and can be changed as appropriate.

  In the above-described embodiment, the example in which the plurality of first raised portions 11 are arranged so as to be line-symmetric with respect to the reference line L2 has been described. However, the plurality of first raised portions 11 are arranged symmetrically with respect to each other. The arrangement of the first raised portions 11 can be changed as appropriate. For example, as shown in the comforter 31 of FIG. 7A, the directions of the two first raised portions 11 adjacent in the width direction D1 may be the same.

  In the above-described embodiment, the example in which the rectangular third raised portions 13 are provided at both ends in the width direction D1 has been described. However, as shown in the comforter 41 of FIG. 7B, the third raised portions 13 are provided. Instead, a triangular fourth raised portion 14 may be provided. Thus, the rectangular third raised portion 13 can be omitted.

  In the above-described embodiment, an example in which two openings 8 into which the nozzles 7 enter is described. However, the opening 8 may be formed at one place or three or more places. In the above-described embodiment, the example in which the opening 8 into which the nozzle 7 enters is formed on the short sides 2a and 3a has been described. However, the location of the opening 8 can be changed as appropriate. Furthermore, in the above-described embodiment, the second gusset portion 4b having two cloth-like portions 4d has been described. However, the shape, number and size of the gusset portions constituting the comforter 1 can be changed as appropriate.

  In the above-described embodiment, the example in which the internal space S between the outer material 2 and the lining 3 is partitioned by the gusset portion 4 has been described. However, the outer surface 2 and the lining 3 do not have to be partitioned by the gusset portion 4, and the gusset portion 4 can be omitted. For example, instead of the gusset portion 4, a straight stitch portion (tataki quilt) in which the outer fabric 2 and the lining 3 are directly stitched together may be provided, and the comforter according to the present invention is a thin towel for use in summer, for example.
