It is preferable that an opening is formed. By forming the penetration part 8, the cushion member 1 can ensure the air permeability of the up-down direction more reliably. Moreover, the penetration part 8 has made the space connected with respect to the said recessed part 10 (10a, 10b), and provides higher air permeability to a cushion member.

(Strip group 3)
The combination structure 2 includes the first strip-shaped strip group 3a and the second strip-shaped strip group 3b as the strip-shaped strip group 3, and each of the strip-shaped strip groups 3 includes a plurality of strip-shaped strips. It consists of four pieces. The strip-shaped piece group 3 is formed by arranging a plurality of strip-shaped pieces 4 with their longitudinal directions L aligned with each other along the widthwise direction W. In the strip-shaped piece group 3, the adjacent strip-shaped pieces 4 and 4 are arranged at intervals. Therefore, the plurality of strips 4 constituting the first strip group 3a are aligned in the longitudinal direction La and arranged at intervals along the width direction Wa, so that the first strip A plurality of band-like pieces 4 that form the piece group 3a and constitute the second band-like piece group 3b are aligned at intervals along the direction of the width direction Wb with the direction of the longitudinal direction Lb aligned. A second strip-shaped piece group 3b is formed. The distance between the adjacent strips 4 and 4 in the first strip piece group 3a and the second strip piece group 3b depends on various conditions such as the size and thickness of the rising portion 11 and the falling portion 12 of each strip piece 4. Accordingly, the size of the first belt-like piece group 3a and the second belt-like piece group 3b can be appropriately selected so as to be combined in a plain weave.

  In the example of FIG. 1, for each of the first strip-shaped piece group 3a and the second strip-shaped piece group 3b, the strip-shaped pieces 4 constituting the strip-shaped piece group 3 are formed in the same shape as each other. The thing which consists of is adopted. Without being limited to this example, the strip-shaped piece group 3 may be composed of a plurality of types of strip-shaped pieces 4 formed in a predetermined shape. For example, among a plurality of strips 4, some strips and other strips have different physical properties such as hardness and rebound resilience, and the strip strips 3 are composed of two types of strips 4. May be. Here, examples of the object to be different between the strips 4 constituting the strip group 3 include width, thickness, shape, color, pattern and the like in addition to the above-described physical properties. In addition, although the case where the strip-shaped piece group 3 is configured by two types of strip-shaped pieces 4 is illustrated above, the strip-shaped piece group 3 may be configured by three or more types of strip-shaped pieces 4. Further, when the cushion member 1 is formed by using the belt-like pieces 4 having different physical properties such as hardness in the first belt-like piece group 3a and the second belt-like piece group 3b, the cushion member 1 is convex. The strips 4 having different physical properties are alternately arranged on the upper surfaces of the portions 5a and 5b. When the cushion member 1 is used for bedding such as a mattress, the bedding has better body pressure dispersibility and the like.

  In addition, some of the strips 4 of the plurality of strips 4 constituting the strip group 3 may have different physical properties, shapes, patterns, colors, and the like from the other strips 4. Therefore, it is easy to select the belt-like piece 4 and form the belt-like piece group 3 by combining a plurality of types of belt-like pieces 4, and to form the cushion member 1 using such a belt-like piece group 3. For this reason, according to the cushion member 1, it becomes possible to respond finely according to an individual's physique and preference. For example, when manufacturing as a mattress, by using a high-hardness band-like piece 4 corresponding to a place where the pressure such as the waist is large, the risk of excessive subsidence occurring at that place is suppressed, The sleeping posture can be improved.

  For each of the first strip-shaped piece group 3a and the second strip-shaped piece group 3b, the arrangement pattern of the strip-shaped pieces 4 when the strip-shaped pieces 4 constituting the strip-shaped piece group 3 are arranged along the width direction W is a plain weave pattern. The patterns that can be combined with can be appropriately selected. For example, as the arrangement pattern of the strips 4, as shown in FIG. 1, FIG. 2A, etc., the adjacent strips 4, 4 are reversed from each other (the adjacent strips 4, 4 are reversed to each other) The pattern formed by arranging the strips 4 and 4 may be selected so as to be in such a state.

(Strip 4)
As shown in FIGS. 2B, 5A to 5F, etc., each of the strips 4 constituting the strip group 3 has a rising portion 11 in the vertical direction H from one end to the other end along the longitudinal direction L. It consists of the strip-shaped resin foam 13 formed in the up-and-down shape where the falling part 12 is repeated. That is, the strip 4 includes a rising portion 11 and a falling portion 12 that are alternately arranged, and a rising portion 9 that rises obliquely from the falling portion 12 and continues to the rising portion 11. Are connected by the upright part 9.

It has an external shape that rises and falls in a wave shape toward the edge. In this case, the corrugated shape that forms the appearance of the strip 4 may be formed to have a trapezoidal appearance as shown in FIG. 2B or FIG. As shown in FIG. 5B, it may be formed to have a sinusoidal appearance.

(Surface shape on the upper surface 14 side and the lower surface 15 side of the strip 4)
The surface shape on the upper surface 14 side and the lower surface 15 side of the strip 4 may be formed in a shape that coincides with each other as shown in FIGS. 5A and 5B, or formed in different shapes as shown in FIGS. 5C and 5F. May be. It should be noted that when the surface shapes on the upper surface 14 side and the lower surface 15 side are matched, or the upper surface 14 and the lower surface 15 are different from each other as shown in FIG. When repeating the shape, as shown in FIG. 7A, the resin foam base body 20 is sequentially cut so as to draw the same locus along the broken lines (P1, P2, P3,...) By secondary processing or the like. As shown in FIG. 7B, the strip-shaped resin foam 13 is sequentially cut into a predetermined shape to form the strip-shaped piece 4, thereby suppressing the loss of the resin material that is the raw material of the resin foam base 20 and efficient resource utilization. It can contribute to effective use. However, in the example of the strip-like piece 4 in FIG. 5F, when the strip-shaped resin foam 13 is sequentially cut out, the upper surface 14 and the lower surface 15 of the strip-like piece 4 face each other, unlike FIG. 7B. In addition, the upper surface 14 and the lower surface 15 of the strip | belt-shaped piece 4 show the surface turned to the upper surface 6 side and the lower surface 7 side of the combination structure 2, respectively.

(Resin constituting the resin foam 13)
As the resin constituting the belt-shaped resin foam 13, a resin used as a foam material generally used for bedding, such as polyurethane and polyethylene, can be employed.

  As the belt-shaped resin foam 13, a soft synthetic resin foam is preferable from the viewpoint that it can be suitably applied to uses such as bedding, and among them, a soft polyurethane resin foam can be preferably used. .

(Number of laminated resin foams 13)
The band-shaped resin foam 13 may be formed as a single layer as in the examples shown in FIGS. 5A to 5C and 5F, but may be formed as a stacked body in which a plurality of layers are stacked. For example, as shown in FIG. 5D, the belt-shaped resin foam 13 may form a laminated body in which a laminated structure is formed as a whole, or a laminated body in which a laminated structure is partially formed as shown in FIG. 5E. May be done. FIG. 5D illustrates a case where the belt-shaped resin foam 13 has a structure in which two different layers 130 and 131 are laminated on the whole. FIG. 5E illustrates the case where the belt-shaped resin foam 13 has a structure in which two different layers 132 and 133 are partially laminated.

(Preparation of combined structure 2)
The combined structure 2 can be prepared by combining the first strip-shaped piece group 3a and the second strip-shaped piece group 3b in a plain weave shape. Specifically, a first strip-shaped piece group 3a and a second strip-shaped piece group 3b configured with a predetermined arrangement pattern are prepared. Next, the first belt-like shape is formed such that the longitudinal direction La of the belt-like piece 4 constituting the first belt-like piece group 3a and the longitudinal direction Lb of the belt-like piece 4 constituting the second belt-like piece group 3b intersect each other. The piece group 3a and the second strip-like piece group 3b are arranged. Then, with respect to the rising part 11 of the band-like piece 4 constituting the first band-like piece group 3a, the lower part 12 of the band-like piece 4 constituting the second band-like piece group 3b is overlapped on the lower side and the first convex part 5a, and the rising part 11 of the strip 4 constituting the second strip group 3b overlaps the lower part 12 of the strip 4 constituting the first strip group 3a. The first belt-like piece group 3a and the second belt-like piece group 3b are combined so as to form two convex portions 5b. Thereby, the 1st strip-shaped piece group 3a and the 2nd strip-shaped piece group 3b will be combined in plain weave form, and the combination structure 2 is formed.

  Regarding the first strip-shaped piece group 3a and the second strip-shaped piece group 3b to be prepared, when the first strip-shaped piece group 3a and the second strip-shaped piece group 3b are combined in a plain weave shape, one raised portion of each other It is preferable that the first strip-shaped piece group 3a and the second strip-shaped piece group 3b are selected such that all of the 11 and the lowered portion 12 overlap with either the other raised portion 11 or the lowered portion 12. . In this case, all of the rising part 11 and the falling part 12 are used for forming the convex part 5 without waste, and the convex part can be efficiently formed.

  In the example of FIG. 1, FIG. 2A, FIG. 2B, etc., the belt-like piece 4 constituting the first belt-like piece group 3a and the belt-like piece 4 constituting the second belt-like piece group 3b are provided with rising portions 11 having the same shape.

In this case, in the cushion member 1, the first convex portion 5a and the second convex portion 5b can align the shapes on the upper surface 6 side to substantially the same shape, and form the convex portions 5 more uniformly. can do.

  In the examples of FIGS. 1, 2A, 2B, etc., the strip 4 of the first strip group 3a has a trapezoidal appearance when the direction along the width direction Wa of the strip 4 is the line-of-sight direction. Is selected to be formed. This is the same for the strip 4 of the second strip group 3b shown in the example of FIG. 1, and the strip of the second strip group 3b when the direction along the width direction Wb is the line-of-sight direction. The piece 4 has a trapezoidal wavy appearance. In this case, when the first strip-shaped piece group 3a and the second strip-shaped piece group 3b are combined in a plain weave shape, the rising portion 11 and the second strip-shaped portion of the strip-shaped piece 4 constituting the first strip-shaped piece group 3a. The descending portion 12 of the strip-shaped piece 4 constituting the piece group 3b and the descending portion of the strip-shaped piece constituting the first strip-shaped piece group and the raised portion of the strip-shaped piece constituting the second strip-shaped piece group are in surface contact. It becomes easy and the shape of the 1st convex part and the 2nd convex part becomes easier to stabilize.

  In addition to the example of FIG. 1, for example, as shown in FIG. 6, the band-like piece 4 of the first band-like piece group 3 a is obtained when the direction along the width direction Wa of the band-like piece 4 is the line-of-sight direction. Alternatively, a material having a sinusoidal appearance may be selected. The same applies to the strip 4 of the second strip group 3b shown in the example of FIG. In this case, in the first convex portion 5a and the second convex portion 5b formed when the first strip-shaped piece group 3a and the second strip-shaped piece group 3b are combined in a plain weave shape, the first strip-shaped piece It becomes easy to form a gap 17 between the strip 4 constituting the group 3a and the strip 4 constituting the second strip group 3b, and the first convex portion 5a and the second convex portion 5b. The air permeability can be further improved.

(Use of cushion member 1)
Such a cushion member 1 can be used as it is as a bedding such as a mat or a pillow. Moreover, it can also be used in the state combined with the support member 101 as a member which comprises the cushion body 100 mentioned later.

  In the cushion member 1, in the 1st convex part 5a and the 2nd convex part 5b, the strip | belt piece 4 which comprises the 1st strip | belt-shaped piece group 3a which overlaps, and the strip | belt-shaped piece which comprises the 2nd strip | belt-shaped piece group 3b 4 is preferably in an unbonded state. When such a non-adhesion state is formed, even if stress is applied to the cushion member 1 in the licking direction (arrow F direction) as shown in FIG. Of these, the strip 4 disposed on the upper surface 6 side can be slightly slid in the direction of the arrow T with respect to the strip 4 disposed on the lower surface 7 side, so that some stress can be received. The possibility that the entire periphery of the projection is pulled in the direction in which the convex portion 5 is crushed is reduced. Moreover, since the strip | belt piece 4 is comprised from the resin foam, even if it receives stress to the arrow F direction, the strip | belt piece 4 arrange | positioned at the upper surface 6 side is arrange | positioned at the lower surface 7 side. 4 can be slightly depressed, and the possibility that the convex portion 5 is completely crushed can be reduced. Furthermore, when the cushion member 1 is formed with the recesses 10a and 10b above and below the upright portion 9, even if the stress is applied in the direction of the arrow F, the strip 4 disposed on the lower surface 7 side is placed. 40, the recess 10b is prevented from being completely crushed by being interposed between the mounting surface 40a and the strip 4 disposed on the upper surface 6 side. The air permeability can be effectively maintained.

Although the support member 101 can select the material applicable according to the use of beddings, such as a mat | matte or a pillow, from a viewpoint of suppressing the possibility of feeling a great touch difference between the support member 101 and the cushion member 1. It is preferable that the cushion member 1 is made of the same material. That is, it is preferable that the support member 101 is formed of a resin foam, similarly to the strip-shaped piece constituting the cushion member 1.

  The support member 101 may have a single layer structure, but may have a laminated structure as illustrated in FIGS. 9 and 10. For example, the support member 101 may have a laminated structure of the foam layer 103 and the gel layer 104. In this case, the support member 101 may have a mounting region formed on the surface side on which the gel layer 104 is laminated. As a resin constituting the foam layer 103, a resin constituting a resin foam similar to the strip-like piece constituting the cushion member 1 may be appropriately selected. Furthermore, as shown in the example of FIG. 10, the support member 101 may be provided with a through hole 106 in the cushion body thickness direction or the like for the purpose of appropriately improving the air permeability. When the through-hole 106 is provided in the support member 101, a higher transpiration eliminating effect is exhibited due to a synergistic effect with the breathability of the cushion member 1.

(Gel layer 104)
The gel layer 104 is a layer made of urethane resin or the like. Since the gel layer is formed on the support member 101, a region having a temperature lower than the surroundings is generated between the cushion member 1 and the support member 101, and the effect of satisfactorily suppressing steaming in combination with the high air permeability of the cushion member. Can be realized. In particular, when the cushion body 100 is used as a bedding such as a pillow, there is no feeling of stuffiness, and a cool air inside is felt during operation such as turning over, so that a comfortable sleep can be obtained even in difficult times such as summer. be able to.

(Formation of cushion body 100)
The cushion body 100 can be laminated and formed by performing an attachment process for attaching the cushion member 1 on the attachment region of the support member 101. As an implementation method of the attachment step, an attachment fixation method can be selected as appropriate, and for example, a method of fixing the cushion member 1 to the support member 101 with the adhesive or the like entirely or partially can be exemplified. In the example of FIG. 3, as also shown in FIGS. 4A to 4C, the cushion member 1 has an adhesive layer 102 made of an adhesive on the support member 101 on the lower surface side of the first convex portion 5 a and the second convex portion. As a result, the laminated structure of the support member 101 and the cushion member 1 is formed, and the cushion body 100 is prepared. In addition, this example is an example, and in forming the cushion body 100, the cushion member 1 does not necessarily have to be directly bonded to the instruction member 101. For example, as shown in FIG. The cushion member 1 can also be laminated on the support member 101 by adhering a frame member 105 made of a foam or the like to the periphery of the substrate and adhering the frame member 105 to the support member 101.

(Use of cushion body 100)
The cushion body 100 can be suitably used as bedding such as a mat or a pillow. According to the cushion body 100, since the cushion member 1 is provided as shown in FIG. 8B, even if the stress in the arrow F direction is applied to the convex portion 5 so that the convex portion 5 is crushed in the licking direction, The portion 5 can be slid slightly in the direction of the arrow T to receive stress, and the possibility that the entire periphery of the convex portion 5 is pulled in the direction in which the convex portion 5 is crushed is reduced. Moreover, since the recessed part 10a is formed in the cushion member 1 of the cushion body 100 at least above the upright part 9 and the uneven structure is formed on the upper surface 6 side, according to the cushion body 100, the uneven structure is formed. Air permeability in the surface direction can be ensured using the recess 10a as a ventilation path. Further, according to the cushion body 100, when the convex portion 5 slides slightly in the direction of the arrow T and receives stress, the convex portion 5 is unlikely to be completely crushed, and the concave portion 10a having the concavo-convex structure is ventilated. The problem of loss of air permeability in the surface direction as the road is reduced. In particular, when the cushion body 100 is configured using the cushion member 1 in which the concave portions 10a and 10b are formed on the upper and lower sides of the upright portion 9, the convex portions 5 and the concave portions 10a are almost completely provided. Even if it is in a state of being crushed, the recess 10b on the lower side of the upright portion 9 is not easily crushed, and the air permeability in the surface direction can be ensured more reliably. That is, for example, with respect to the rising portion 9 that rises obliquely from the first convex portion 5a toward the second convex portion 5b, stress is applied obliquely to the first convex portion 5a and the first convex portion When the case 5 is crushed, even if the two convex strips are compressed by compressing the first convex portion 5a and the second convex portion 5b due to stress, the strip shape constituting the second convex portion 5b is compressed. Of the strips 4, the strip 4 connected to the upright portion 9 further includes a single strip 4 between the support member 101, so that a space is secured between the support member 101 and the standup 9. Is maintained, and the air permeability in the surface direction is more reliably ensured. Further, in the cushion body 100, the support member 101 is formed of a resin foam, so that even if stress is applied in the direction of crushing the protrusion 5, the protrusion is inward in the support member 101 (arrow V direction). Since the band-like piece 4 constituting the film is slightly sunk, the convex part 5 is not crushed and the shape is easily maintained.

  Next, the example which manufactured the pillow which consists of the cushion body 100 is demonstrated still in detail as an Example.

(Process I: Production of cushion member)
A soft urethane foam having a hardness (25% compression) of 90 N and a compression residual strain (75% compression) of 10%, having a width of 20 mm and a thickness of 10 mm at the rising and falling portions, and a band shape as shown in FIG. 5A. Piece 4 was produced. Next, the belt-like piece 4 was knitted into a plain woven shape, and a cushion member as shown in FIGS. 1 and 2 having a longitudinal length of 500 mm, a depth of 300 mm, and a thickness of 20 mm was produced.

Example 1
A frame material made of a flexible urethane foam having a width of 50 mm and a thickness of 20 mm is bonded to the four circumferences of the cushion member manufactured in the above (Step I), and the hardness (25% compression) is 50 N, and the compression residual strain (75%). A pillow was manufactured by adhering the frame material to the upper surface of a support member made of a soft urethane foam having a compression ratio of 15%, a longitudinal length of 600 mm, a depth of 400 mm, and a thickness of 50 mm.

Example 2
A gel made of urethane resin is cured on a film made of urethane resin to produce a gel sheet having the same width and depth as the cushion member 1 in (Step I), and the same flexible urethane as the support member used in Example 1 A pillow similar to that of Example 1 was manufactured except that a support member was formed by laminating the gel sheet on the upper surface of the foam.

Comparative Example 1
A urethane foam sheet (one piece) having the same width, depth and thickness as the cushion member obtained in (Step I), which is the same flexible urethane foam as the strip 4 used in the cushion member obtained in (Step I). The same pillow as in Example 1 was manufactured except that the urethane foam sheet was used instead of the cushion member.

  The pillows obtained in the above Examples and Comparative Examples were evaluated as follows.

[Temperature measurement]
The temperature change inside the pillow was measured when the pillow was used in a summer environment, that is, in a hot and humid environment, assuming that the person's head is on the head. That is, under an environmental condition of an air temperature of 28 ° C. and a humidity of 50% RH, a heat source of 36 ° C. was installed on the upper surface of each pillow, and a weight of 5 kg was placed on the heat source, and between each laminate, that is, Example 1 And in Example 2, a thermocouple was installed between the cushion member and the support member, and in Comparative Example 1 between the urethane foam sheet and the support member, and the temperature change inside the pillow with time was measured. The results are shown in FIG.

  As can be seen from the results shown in FIG. 11, the pillow of Example 1 in which the cushion member of the present invention is laminated on the support member has a lower temperature rise inside the pillow than Comparative Example 1 in which the urethane foam sheet is laminated, and 60 minutes. Later, a temperature difference of 2 degrees or more appeared inside the pillow. Moreover, Example 2 which laminated | stacked the gel layer between the cushion members as a supporting member maintained about 1 degree lower temperature than Example 1. FIG. As a result, when the cushion body in the present invention is a pillow, even when used under hot and humid conditions in summer, unlike a pillow made of a conventional soft urethane foam, it has high breathability, It was difficult to collect heat, and a pillow with a sense of stuffiness was obtained.

  In addition, the conventional pillow with a gel layer on the upper surface feels cold in the initial stage of use, but because it is in direct contact with the human body (head) (excluding covers, etc.), the temperature of the gel layer becomes a body temperature in a relatively short time. In Example 2 having the cushion member of the present invention on the upper surface, the head rests on the pillow through the cushion member, so that the extreme temperature up to the vicinity of the body temperature in the gel layer is raised. Since the temperature did not increase and the body temperature of the head was not extremely deprived even when touched, the feeling of stuffiness was satisfactorily suppressed for a long time, and a pillow that could be used comfortably was obtained.

Example 3
Furthermore, the strip in the longitudinal direction in the pillow of Example 1 is the same strip-shaped strip made of a soft urethane foam having a hardness (25% compression) of 75 N and a compression residual strain (75% compression) of 10%. Except for the above, a pillow was produced in the same manner as in Example 1. As a result, the hardness of adjacent convex portions was different, and thus very excellent body pressure dispersibility was exhibited. Thus, according to the pillow of Example 3, it can be seen that a pillow that gently supports the head can be obtained without feeling the pressure of being caught by the protrusion, unlike the uneven shape by the conventional profile processing. .
