It is preferable that the number of driving of the side ground 14 is formed in a range of 390 to 414.

As shown in FIGS. 1 and 2, the bending means 16 includes a suture line for stitching the front and back of the side ground 14. The suture line includes, for example, two oblique suture lines 18 and 20 disposed in a diagonal direction intersecting a center line XX extending in the longitudinal direction of the pillow 10 through an intermediate point in the width direction of the pillow 10. . The two diagonal suture lines 18 and 20 are arranged at a predetermined interval in the length direction of the pillow 10.
One oblique suture line 18 is disposed between one end of the pillow 10 in the length direction and the center of the pillow 10 in the length direction, and the other oblique suture line 20 is the other in the length direction of the pillow 10. It is disposed between the end and the center of the pillow 10 in the length direction. For example, as shown in FIGS. 1 and 3, one oblique suture line 18 and the other oblique suture line 20 pass through a middle point in the longitudinal direction of the pillow 10 and a center line Y− extending in the width direction of the pillow 10. They are arranged symmetrically with respect to Y.

  In this case, in particular, the pillow 10 has, for example, as shown in FIG. 3, four corners formed by abutting two opposing linear long sides 10 </ b> A and 10 </ b> B of the pillow 10 and one oblique suture 18. The one pair of opposite angles θ1 and θ1 on the opposite side of one diagonal stitch line 18 are equal in an angled relationship, and are set to 45 degrees, for example. Similarly, of the four corners formed by the two straight long side portions 10A, 10B facing each other of the pillow 10 and one diagonal suture line 20 in contact with each other, the opposite side of the one diagonal suture line 20 is present. One pair of angles θ2 and θ2 that are opposed to each other are in a complex angle relationship and are set to 45 degrees, for example.

  In the present embodiment, for example, as shown in FIG. 3, the two diagonal suture lines 18, 20 and a pair of opposite sides opposed to the width direction of the pillow 10, that is, the linear long side portion 10 </ b> A, The two oblique suture lines 18 and 20 are arranged so that the part surrounded by 10B has a trapezoidal shape in plan view.

  In the present embodiment, as shown in FIG. 3, the contact end points at which the two linear long side portions 10A and 10B are in contact with one oblique suture line 18 are 22 and 24, and the two linear lengths are used. The contact end points at which the side portions 10A and 10B abut against the other oblique suture line 20 are 26 and 28, and the length from the one end 30 (vertex) in the length direction of the linear long side portion 10A to the contact end point 26 Is L1, the length from the other end 32 (vertex) in the length direction of the linear long side portion 10A to the contact end point 22 is L2, and the length between the contact end point 22 and the contact end point 26 is L3. Further, the length from the one end 34 (vertex) in the length direction of the linear long side portion 10B to the contact end point 28 is L4, and the other end 36 (in the length direction of the linear long side portion 10B) The length from the vertex) to the contact end point 24 is L5, and the contact end point 24 and the contact end point 28 are When the length and L6, and is set, for example, L1 = L2 = 100cm, L3 = 30cm, L4 = L5 = 60cm, L6 = 110cm.

  In the present embodiment, for example, as shown in FIG. 2, the two oblique stitches described above are sewn by stitching the front and back sides of the side ground 14 via the reinforcing pieces 38 arranged between the front and back sides of the side ground 14. Lines 18 and 20 are formed. In this case, the portions of the oblique suture lines 18 and 20 are subjected to sewing means such as double stitching (double needle stitching), so that the portions of the oblique suture lines 18 and 20 are interposed via the reinforcing pieces 38. It is to be reinforced.

  In the above-described embodiment example shown in FIGS. 1, 2 and 3, the PPT fiber in which the low resilience material forming the intermediate member 12 has a fiber thickness in the range of, for example, 0.9 to 6.0 deniers, in particular. (Polytrimethylene terephthalate fiber) is included, so when the user deposits his / her body on the pillow 10, it feels soft and has a soft feeling that will hold the body moist, with little push-back and less body pressure. Disperses and reduces the burden on the body due to the repulsive force. In addition, the side ground 14 is formed of a high-density fabric having a driving number of, for example, in the range of 390 to 414, and has a function of delaying air escape inside the side ground 14. This pillow 10 can amplify the low repulsion feeling as a pillow in combination with the unique low repulsion function of the middle material 12. That is, by slowing the sinking speed of the pillow when the user deposits the body on the pillow 10, the body gently and slowly lands on the pillow, and the burden on the body due to the repulsive force is reduced.

4 is an illustrative view for explaining the function of the side land applied to the pillow shown in FIG. 1, FIG. 2 and FIG. 3, and FIG. 5 is compared with the pillow shown in FIG. 1, FIG. It is an illustration figure for demonstrating the comparative example performed.
In the side 14 applied to the pillow 10 shown in FIGS. 1, 2, and 3, as shown in FIG. 4A, pressure is applied to the pillow 10 by leaving the body in the pillow 10. In this case, as described above, the side land 14 is formed of a high-density side fabric and has low air permeability. Therefore, as shown in FIG. The sinking of the pillow 10 due to the air escape inside is relaxed. That is, in combination with the low resilience function unique to the intermediate material 12, the low resilience feeling as a pillow can be amplified, and as described above, the sinking speed of the pillow can be delayed.
On the other hand, in the pillow 40 of the comparative example in which the side ground 44 is formed of a so-called rough side fabric having a low density, as shown in FIG. When the pressure is applied to the pillow 40, the air permeability of the side ground 44 is increased. Therefore, as shown in FIG. The air easily escapes instantly, and the pillow 40 is crushed by the sinking of the pillow 40, thereby causing a problem that the pillow 40 is crushed.

  As described above, in the above-described embodiment example shown in FIGS. 1, 2 and 3, the side ground 14 is formed of a high-density fabric with a large number of drivings. This makes it possible to inhibit the outflow of fiber chips and dust, which is one of the causes, and a pillow useful as an allergy countermeasure can be obtained. Moreover, in the above-mentioned embodiment example, since the side place 14 is formed with a high-density polyester resin, and the inner material 12 is formed with PPT fibers (polytrimethylene terephthalate fibers), the pillow 10 is washed with water. Sweat and dirt can be easily washed away, and it is relatively fast-drying, so it can be washed at home.

  In the above-described embodiment, for example, as shown in FIGS. 6 and 7, the pillow 10 is used by being folded in a U shape on the surface side of the pillow 10 along two oblique suture lines 18 and 20. it can. The U-shaped bent portion includes two opposite bent side portions 46 and 48 and a connecting side portion (center portion) 50 that connects the two bent side portions 46 and 48. Therefore, in this pillow 10, for example, as shown in FIG. 8, the pillow 10 has a function as a pillow for placing the head on the connection side (center) 50 side connecting the two bent side portions 46 and 48 facing each other in a U shape. The two U-shaped opposing bent side portions 46 and 48 can be provided with a function as a body pillow.

  The angle when the pillow 10 is bent along the two oblique suture lines 18 and 20 bends more flexibly according to the above-described material characteristics of the intermediate material 12 and the side fabric 14, for example, as shown in FIG. By folding the two bent sides 46, 48 inward according to the user's preference, the body can be opened and sleep more, and by bending the two bent sides 46, 48 outward, the body can be more You can also close and sleep.

  Furthermore, in the above-described embodiment, for example, as shown in FIGS. 11 and 12, the pillow 10 is used by being folded in a U shape on the back surface side of the pillow 10 along two oblique suture lines 18 and 20. You can also. Also in this case, as in the case of folding in the above-described folding direction (see FIGS. 6 to 8), the pillow 10 has two U-shaped opposite bent side portions 46 and 48 as shown in FIG. 13, for example. A function as a pillow that has a function as a pillow that puts the head on the connection side (center) 50 side that connects the two, and entrusts the body to both of the two U-shaped opposing bent side portions 46 and 48 Can be given.

  In this embodiment, the user sets the height of the connecting side (center) 50 (hereinafter referred to as “the height of the pillow”) on which the head is placed according to the folding direction of the two bent portions. It is possible to adjust the height of the pillow on the connecting side portion (center portion) 50 to be placed to a height suitable for the user. That is, as shown in FIGS. 6 and 7, the two bent side portions 46 and 48 are compared with the height H <b> 1 (see FIG. 9) of the pillow 10 when the pillow 10 is bent on the surface side. For example, as shown in FIGS. 11 and 12, the height H2 (see FIG. 14) of the pillow 10 can be increased when the two bent sides 46 and 48 are bent toward the back side of the pillow 10. It has become.

  Regardless of the case in which the folding direction of the two opposite bent side portions 46 and 48 is any of the above-described cases, the two U-shaped opposite bent side portions 46 and 48 are, for example, FIG. 6, FIG. As shown in FIG. 13, since the body is received so as to support the user with both arms from both the shoulder, the scapula and the back of the user, the pillow 10 folded in a U-shape Neck and shoulder steps and gaps are less likely to be created, reducing the burden on the neck and shoulders. Therefore, the pillow 10 can give the user a good sleep in a relaxed state without placing a burden on the body. As a result, sleeplessness, stiff shoulders, low back pain, hemorrhoids, apnea, etc. can be resolved.

  In the present embodiment, as shown in FIG. 3, the two diagonal suture lines 18 and 20 are arranged at the intermediate point in the longitudinal direction of the pillow 10, in this case, through the center of the longitudinal direction, in the width direction of the pillow 10. By having a configuration that is arranged symmetrically with respect to the center line Y-Y extending in the direction, the two opposing folding side portions 46 and 48 are bent line-symmetrically along the two oblique suture lines 18 and 20. Therefore, the bent sides 46 and 48 on both sides are balanced. Therefore, the action / effect of the pillow 10 described above is more effectively exhibited.

  In the above-described embodiment, as shown in FIGS. 15 and 16, for example, the pillow 10 can be used by bending it into, for example, an L shape along one specified oblique suture line 20. In this case, as shown in FIG. 16, the L-shaped bent portion has a function as a pillow 10 for putting a head on the L-shaped short side 52 side, and on the L-shaped long side 54 side. With the function as a body pillow, the function of the pillow for putting the head on and the function of the body pillow for covering the body can be integrated. In this case, the user can feel as if he is wearing an arm pillow, and the user can deposit his / her body on the long side 54 side of the L-shaped bent portion to reduce the burden on the body.

  In the above-described embodiment, the bending means 16 can be freely bent into a desired usage mode. At this time, the bending means 16 prevents the intermediate material 12 from being displaced in the side ground 14 by the diagonal suture lines 18 and 20 that stitch the front and back of the side ground 14. It is possible to maintain the desired usage state that is bent in a stable state, and to have excellent shape retention. And, if the pillow 10 is returned from the folded state to the original state, it has a function as a long body pillow that reduces the burden on the body by depositing the whole body. The movement of the sleeping person next to the person is relaxed, making it difficult for the person to be affected by the movement.

  In addition, in the present embodiment, for example, as in the prior art according to Patent Document 1 described above, the amount of the stuffing to be sealed by the user himself / herself in the bar-shaped bunker side (side land) is determined according to the type and size of the stuffing. And according to the diameter and length of the rod-shaped basket, there is no need for the user to adjust individually, and handling at the time of use is extremely simple.

In the embodiment described above, for example, two oblique suture lines 18 and 20 constituting the bending means 16 are arranged between one end and the other end in the length direction of the pillow 10 and the center in the length direction of the pillow 10. However, at least one or more diagonal suture lines are arranged at intervals between one end and / or the other end in the length direction of the pillow 10 and the center in the length direction of the pillow 10. In this case, the pillow 10 may be bent in an L shape along one specified oblique suture line among many oblique suture lines.
Further, at least 2 so that a part surrounded by two specified oblique suture lines and a pair of opposite sides opposed to the width direction of the pillow 10 has a trapezoidal shape in plan view. Two oblique suture lines may be arranged so that the pillow 10 can be bent in a U shape along the two specified oblique suture lines.

In addition, as a cross-sectional shape of the PPT fiber (polytrimethylene terephthalate fiber) constituting the intermediate member 12, a round cross-section, a hollow cross-section, a modified cross-section, or the like may be appropriately selected as necessary. In addition, PPT fibers (polytrimethylene terephthalate fibers) may be used by blending different deniers or fibers having different fiber lengths. Furthermore, it is preferable that PPT fibers (polytrimethylene terephthalate fibers) are not thermally bonded to each other in order to realize softness suitable for a pillow. Furthermore, if necessary, it is also possible to mix natural fibers and other chemical fibers with PPT fibers (polytrimethylene terephthalate fibers) to an extent that does not impair the object of the present invention. In particular, considering the easy washability of the pillow 10, it is possible to appropriately include polyethylene terephthalate fibers having a reduced inter-fiber friction coefficient and bulky polyethylene terephthalate fibers.
Moreover, the side ground 14 may be a collection of fibrous materials such as a collection of high-density synthetic fibers other than polyester fibers as ultrafine fibers having a low resilience function.

  In the above-described embodiment example, a pillow cover (not shown) that covers the side ground 14 can be appropriately provided, and therefore, dirt prevention and washing are further facilitated. In addition, it is preferable to form this pillow cover (not shown) with the cloth | tensile_strength which does not impair the low resilience function of the middle material 12. FIG. As the stretchable fabric, for example, a knitted fabric such as flat knitting, rib knitting, and pile knitting is preferable, and it is also preferable to use a knitted fabric including elastic fibers such as spandex.
