Description

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

Conventionally, comforters such as duvets have been known, and comforters are used by being hung on the user's body. Japanese Unexamined Patent Publication No. 11-9410 discloses a duvet provided with an outer material, a lining and an intermediate cloth. The intermediate cloth is arranged between the outer material and the lining, and a narrow band-shaped gusset is provided between the intermediate cloth and the outer material and between the intermediate cloth and the lining. This gusset partitions the internal space between the intermediate cloth and the outer material, and the 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 each internal space with the contents in this way, a plurality of ridges are formed on the duvet with the gusset as a boundary. In the above-mentioned duvet, a plurality of diamond-shaped ridges are provided on the outer material, and a plurality of rectangular ridges are provided on the lining. In addition, a plurality of triangular-shaped ridges are provided on the outer edge of the outer material.

Japanese Unexamined Patent Publication No. 11-9410

In the above-mentioned comforter, although a plurality of triangular-shaped ridges are provided on the outer edge of the outer material, a plurality of diamond-shaped ridges are provided on the inner side of the outer edge. Further, the lining is provided with a plurality of rectangular ridges. Here, in the square-shaped raised portion, there is a problem that the contents do not sufficiently spread to the corner portion of the raised portion due to the large number of corners. As described above, since the contents do not spread to the corners of the raised portion, heat can easily escape from the corners of the raised portion. Therefore, in the above-mentioned comforter provided with diamond-shaped and rectangular ridges on the inside of the outer edge, heat escapes from the corners of these ridges, and there is room for improvement in terms of heat retention.

An object of the present invention is to provide a comforter having improved heat retention.

The present inventors have found that the triangular ridge has a smaller number of corners than the quadrangular ridge, which makes it easier for the contents to spread evenly. That is, in the triangular raised portion, the number of the corner portions is smaller than that in the rectangular raised portion, so that the number of portions where the contents are difficult to spread can be reduced. Therefore, by reducing the portion where the contents are difficult to spread, the contents can be spread more evenly in the raised portion. The present invention has been made based on such findings. That is, the comforter according to one aspect of the present invention has a rectangular outer material, a lining that is overlapped with the outer material and extends in a rectangular shape, and a gusset portion and a gusset portion that are three-dimensional quilts that partition the outer material and the lining. It is provided with a plurality of raised portions formed by filling each of the plurality of internal spaces partitioned in the above, and the outer edge of the outer material and the outer edge of the lining are sewn together with each other, and the plurality of raised portions are provided. includes a first raised portion regular triangular in arranged in plan view inside the outer edge, the first raised portion more are aligned along the longitudinal direction of the outer material and lining, gusset portion, It includes a plurality of first gusset portions extending in the width direction of the outer material and the lining, a plurality of second gusset portions extending in the longitudinal direction, and a plurality of third gusset portions inclined in the width direction and the longitudinal direction. The height of the second gusset located at the center in the width direction is higher than that of the second gusset located on both ends in the width direction, and the width direction and between the two first ridges adjacent in the longitudinal direction A third gusset portion that is inclined with respect to the longitudinal direction is interposed.

In this comforter, a plurality of triangular first ridges are arranged inside the outer edge and are arranged along the longitudinal direction. Therefore, by providing the plurality of triangular first raised portions inside the outer edge, more raised portions having a small number of corner portions are provided inside the outer edge. By providing a large number of raised portions having a small number of corners inside the outer edge and filling each of the raised portions with the contents, the contents can be more evenly distributed to each raised portion. Therefore, it is possible to make it difficult for heat to escape from each raised portion, so that the heat retention of the comforter can be improved.

Further, the plurality of raised portions include a second raised portion having an obtuse triangular shape in a plan view arranged at at least 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. You may be. 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 of the raised portion located at at least one end in the longitudinal direction can be reduced. The boundary of the ridge is a part where the contents are not sufficiently distributed as compared with other parts, so that heat easily escapes and the fit to the body is not good. Therefore, as described above, by reducing the number of boundaries of the raised portions located at at least one end in the longitudinal direction, it is possible to make it difficult for heat to escape at the one end. Therefore, the heat retention can be enhanced and the fit to the body can be improved.

Further, the plurality of raised portions include a rectangular third raised portion in a plan view arranged at both ends in the width direction of the outer material and the lining, and the plurality of third raised portions are arranged from one end to the other end in the longitudinal direction. May be lined up. In this case, since the rectangular third raised portion is arranged in a straight line along the longitudinal direction at both ends in the width direction, it is possible to easily hang both ends in the width direction. Therefore, since both ends of the comforter in the width direction are likely to hang down, it is possible to prevent air from entering under the comforter from both ends in the width direction. Since it is possible to prevent air from entering under the comforter in this way, the heat retention of the comforter can be further improved.

According to the present invention, heat retention can be enhanced.

(B) is a sectional view taken along line IIIB-IIIB of FIG. (A) is a diagram showing an opening into which a nozzle for filling the contents is inserted. (B) is a diagram showing a gusset portion in a state where the contents are not accommodated. It is a figure which shows the process of manufacturing a comforter by filling the contents. It is a top view which shows the comforter which concerns on 1st modification. (A) is a plan view which shows the comforter which concerns on the 2nd modification. (B) is a plan view which shows the comforter which concerns on the 3rd modification.

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 designated by the same reference numerals, and duplicate description will be omitted.

FIG. 1 is a perspective view of the 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, for example, placed on a bed mattress. The comforter 1 has a rectangular shape as a whole. The comforter 1 includes a rectangular outer material 2 and a rectangular lining 3 located on the back side of the outer material 2. The outer material 2 and the lining 3 have, for example, the same shape and the same size as each other.

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

As described above, since the comforter 1 is symmetrical with respect to the reference line L1, it can be used in the same manner as when the direction in the longitudinal direction D2 is reversed but not reversed. Further, in the comforter 1, since the shapes of the outer material 2 and the lining 3 are the same, even if the front and back sides are reversed, it can be used in the same manner as when the front and back sides are not reversed.

The material of the outer material 2 and the lining 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 3. The outer material 2 has an outer edge 2A including two short sides 2a and two long sides 2b, and the lining 3 also has an outer edge 3A including a short side 3a and a long side 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, but the lengths of the short sides 2a and 3a and the long sides 2b and the long side 3b are the above examples. It is not limited to, and can be changed as appropriate.

The short side 2a of the outer material 2 and the short side 3a of the lining 3 are combined, and the long side 2b of the outer material 2 and the long side 3b of the lining 3 are combined so that the outer edge 2A of the outer material 2 and the outer edge 3A of the lining 3 overlap. Be done. Then, in this state, the outer edge 2A of the outer material 2 and the outer edge 3A of the lining 3 are sewn together to connect the outer material 2 and the lining 3.

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 material 3. For example, the gusset portion 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. There is.

The first gusset portions 4a are provided at both ends of the comforter 1 in the width direction D1, and the number of the first gusset portions 4a is, for example, six. The second gusset portion 4b is provided at the center and both end sides of the comforter 1 in the width direction D1, and the number of the second gusset portions 4b is, for example, three. The third gusset portion 4c includes a portion extending diagonally upward to the right and a portion extending diagonally upward to the left in a plan view, and the number of the third gusset portion 4c is, for example, eight.

For example, the height of the second gusset portion 4b located at the center of the width direction D1 (the length of the thickness direction D3) may be higher than the height of the second gusset portion 4b located on both end sides of the width direction D1. In this case, the height of the second gusset portion 4b located at the center of the width direction D1 can be 6 cm, and the height of the second gusset portion 4b located on both end sides of the width direction D1 can be 3 cm.

For example, the height of the first gusset portion 4a is 3 cm. Further, the height of the third gusset portion 4c gradually increases (for example, linearly) from the second gusset portion 4b located on both ends in the width direction D1 toward the second gusset portion 4b located in the center of the width direction D1. It is getting higher. The number and height of the first gusset portion 4a, the second gusset portion 4b, and the third gusset portion 4c are not limited to the above examples and can be changed as appropriate.

The comforter 1 is partitioned by the gusset portions 4 arranged as described above so that the number of internal spaces S thereof is 24, and each of the partitioned internal spaces S is filled with the contents 6. .. The content 6 is, for example, feathers (feathers). In the comforter 1, by using the contents 6 as feathers, it is possible to trap heat in the swollen feathers, and it exhibits high heat retention. Further, by filling each internal space S with the contents 6, the comforter 1 forms a plurality of raised portions 10 that rise in the thickness direction D3, which is the out-of-plane direction of the outer material 2 and the lining material 3.

As shown in FIGS. 1 and 3, the raised portion 10 is raised, for example, in a dome shape that is largely rounded and curved upward. The raised portions 10 include a triangular first raised portion 11 provided inside the outer edge 2A of the outer material 2 and the outer edge 3A of the lining 3, and an obtuse triangular triangular second raised portion provided at both ends in the longitudinal direction D2. 12 and a rectangular third raised portion 13 provided at both ends in the width direction D1 are included. The first raised portion 11, the second raised portion 12, and the third raised portion 13 have different shapes.

The first raised portion 11 has, for example, a regular triangular shape. Of the three vertices of the first raised portion 11, at least two vertices are located inside 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 the 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.

A second gusset portion 4b or a third gusset portion 4c is interposed between the plurality of first raised portions 11. Further, the directions of the two first raised portions 11 adjacent to each other in the longitudinal direction D2 are opposite to each other. In this way, by arranging the first raised portions 11 so that the directions of the two first raised portions 11 adjacent to each other in the longitudinal direction D2 are opposite to each other, efficient arrangement of the first raised portions 11 is realized. ..

For example, two rows of the plurality of first raised portions 11 arranged along the longitudinal direction D2 are provided. Further, the rows of the plurality of first raised portions 11 arranged along the longitudinal direction D2 are symmetrical with respect to the reference line L2 extending 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 second raised portion 12 is, for example, an obtuse-angled isosceles triangle. The portion where the second raised portion 12 is provided is a portion where the collar of the user comes into contact. For example, the length of the equilateral side of the second raised portion 12 is 55 cm, and the length of the base 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 of the second raised portions 12 is located on both end sides (short sides 2a, 3a side) of the first raised portion 11 in the longitudinal direction D2. 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. Further, the length of the base of the second raised portion 12 is set to be 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 of the width direction D1 and coincides with the position where the sides of the plurality of first raised portions 11 intersect. Further, the bottom angle and the base of the second raised portion 12 are located at the outer edges 2A and 3A (short sides 2a and 3a). In this way, the bases of the second raised portion 12 facing the obtuse angle coincide with the outer edges 2A and 3A, so that the boundary portion (sewn line portion) of the raised portion 10 is located at the center of the width direction D1 at both ends of the longitudinal direction D2. Is not located. That is, the sewing line portion of the raised portion 10 does not exist at the center of the short sides 2a and 3a.

The third raised portion 13 is provided on both end sides (long sides 2b, 3b side) of the first raised portion 11 and the second raised portion 12 in the width direction D1. A second gusset portion 4b is interposed between the third raised portion 13 and the first raised portion 11. Each third raised portion 13 has a vertically long rectangular shape (extending in the longitudinal direction D2), and one side of the third raised portion 13 extending in the longitudinal direction D2 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 changed as appropriate. Further, 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 third raised portions 13 arranged along the longitudinal direction D2 is, for example, four. The plurality of third raised portions 13 arranged along the longitudinal direction D2 are arranged at positions symmetrical with respect to the reference line L2.

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

The opening 8 is large enough to accommodate the nozzle 7. The opening 8 is formed at one end of the second gusset portion 4b extending in the longitudinal direction D2. Further, 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 have two cloth-like portions 4d. The nozzle 7 is also passed between them. A slit 4e for passing the nozzle 7 is formed in each cloth-like portion 4d. In the two cloth-like portions 4d, the positions of the slits 4e formed in one cloth-like portion 4d and the positions of the slits 4e formed in the other cloth-like portion 4d are different from each other.

In this way, the position of the slit 4e of one cloth-like portion 4d and the position of the slit 4e of the other cloth-like portion 4d are different, so that the nozzle 7 can be easily inserted into each internal space S, and the contents are smooth. It is possible to fill the object 6. Further, each cloth-like portion 4d is folded as shown in FIG. 4B in a state where the content 6 is not contained. However, in a state where the content 6 is put in and the internal space S is inflated, each cloth-like portion 4d rises, and each slit 4e is closed accordingly.

Next, a manufacturing method for manufacturing the comforter 1 by filling each of the internal spaces S with the contents 6 with the nozzle 7 will be described with reference to FIG. The black arrow in FIG. 5 indicates that the nozzle 7 is inserted into each internal space S, and the slit 4e described above is provided at the base of the black arrow.

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

Next, the nozzle 7 is inserted into the second gusset portion 4b in the center of the width direction D1 through the opening 8 and the second raised portion 12, the nozzle 7 is pushed to the innermost portion, and the second position located at the innermost portion. The raised portion 12 is filled with the content 6. Then, while pulling the nozzle 7 from the back to the front, each of the first raised portions 11 located on the left and right of the second gusset portion 4b is filled with the contents 6. After that, the content 6 is filled in the second raised portion 12 located on the opening 8 side, the nozzle 7 is removed from the opening 8, and the two openings 8 are sealed to complete the comforter 1.

Subsequently, the action and effect of the comforter 1 according to the present embodiment will be described. First, in the triangular first raised portion 11 of the present embodiment, the number of corner portions is smaller than that of the rectangular raised portion, so that the number of portions where the content 6 is difficult to reach can be reduced. Therefore, by reducing the portion where the content 6 is difficult to spread, the content 6 can be spread more uniformly in each of the first raised portions 11.

In the comforter 1, a plurality of triangular first raised portions 11 are arranged inside the outer edges 2A and 3A, and are arranged along the longitudinal direction D2. Therefore, by providing a plurality of triangular first raised portions 11 on the inner side of the outer edges 2A and 3A, there are more first raised portions 11 having a smaller number of corner portions on the inner side of the outer edges 2A and 3A. It will be provided.

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

In particular, in the comforter 1, the quadrangular raised portion 10 is not provided inside the outer edges 2A and 3A, and only the triangular first raised portion 11 is arranged. Further, only the triangular first raised portion 11 and the second raised portion 12 are arranged inside the third raised portions 13 at both ends. Therefore, the comforter 1 can exert a higher heat retaining effect.

Further, the plurality of raised portions 10 include obtuse-angled 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 second raised portion 12 is located at both ends of the longitudinal direction D2, the number of boundaries (sewing line portions) of the raised portions 10 located at both ends of the longitudinal direction D2 can be reduced.

The boundary of the raised portion 10 is a portion where the content 6 may not be sufficiently distributed as compared with other portions, so that heat can easily escape and the fit to the body is not good. Therefore, as described above, by reducing the number of boundaries of the raised portions 10 located at both ends of the longitudinal direction D2, it is possible to make it difficult for heat to escape at both ends and improve the heat retention of the collar of the user. Then, the fit to the collar of the user can be improved.

Further, the plurality of raised portions 10 include rectangular third raised portions 13 arranged at both ends of the outer material 2 and the lining 3 in the width direction D1, and the plurality of third raised portions 13 are one ends of the longitudinal direction D2. Lined up from to the other end. Therefore, at both ends of the width direction D1, the rectangular third raised portion 13 is arranged in a straight line along the longitudinal direction D2. 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 (the portion of the third raised portion 13) in the width direction D1 can be easily hung downward.

Therefore, since both ends of the comforter 1 in the width direction D1 are likely to hang down, it is possible to prevent air from entering under the comforter 1 from both ends in the width direction D1. Therefore, since it is possible to prevent air from entering under the comforter 1, the heat retention of the comforter 1 can be further improved.

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

Further, in the method for manufacturing the comforter 1 according to the present embodiment, the content 6 is filled while pulling the nozzle 7 from the back to the front. By filling the contents 6 from the back to the front in this way, the contents 6 can be filled smoothly by the nozzle 7 as compared with the case where the contents 6 are filled from the front to the back.

For example, as shown in the comforter 21 of FIG. 6, the rows of a 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 portion 11 are lined up in four rows. Further, the row of the plurality of first raised portions 11 arranged in the longitudinal direction D2 may be only one row.

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

Further, in the above-described embodiment, an 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, but the plurality of first raised portions 11 are arranged symmetrically with each other. It is not necessary to do so, and the arrangement of the first raised portion 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 to each other in the width direction D1 may be the same.

Further, in the above-described embodiment, an example in which the rectangular third raised portion 13 is provided at both ends in the width direction D1 has been described, but as shown in the comforter 41 of FIG. 7B, the third raised portion 13 has been described. Alternatively, a triangular fourth raised portion 14 may be provided. It is also possible to omit the rectangular third raised portion 13 in this way.

In the above-described embodiment, an example of forming two openings 8 into which the nozzle 7 enters has been described. However, the openings 8 may be formed at one place or three or more places.
