Description

  The present invention relates to a pillow for bedding, and more particularly to a pillow that can gently and stably support a occipital portion from a cervical vertebra portion.

  As pillows for bedding, pillows in the form of being filled with padding such as buckwheat shells in a simple cloth bag and supporting the occipital portion stably by the depression due to the weight of the head at the time of use have been widely used. However, in recent years, with the pursuit of good sleep, for example, as described in Patent Document 1, three large and small cylindrical bags filled with fillings are arranged and integrated in parallel. And a pillow configured to support the neck portion by a large-diameter cylindrical bag on the end side while providing a concave portion for supporting the head at the center in the length direction of the cylindrical bag at the intermediate portion. It has been devised.

Moreover, as described in Patent Document 2, the interior of the pillow body is partitioned into a plurality of chambers by vertical partition cloths, and these chambers are filled with padding such as wood chips and sawdust to exert a deodorizing and antibacterial function. A pillow configured as described above is provided.

  However, just filling the inside of the cylindrical bag or the pillow body gives a wide degree of freedom of movement of the filling in the cylindrical bag or the pillow body, and when the load is applied by the head, In addition, not only does the support height of the head and cervical vertebra part not be determined, but also the unstable sinking of the padding has an unfavorable effect on the support position of the occipital part, However, the shape of the dent produced by receiving the head is also easily deformed due to the large degree of freedom of the padding, and the head does not fit well.

  In addition, even if the pillow body is divided into a plurality of stuffing filling chambers by vertical partition cloths, it has the advantage that different stuffing etc. can be filled in each compartment, but when a load by the head is applied, The vertical partition wall easily bends in either the left or right direction, and the padding also moves in the direction of the bend. The amount of depression of the pillow is large and indefinite, and the head cannot be supported at a stable height. There was a problem.

  The present invention has been made in view of such problems, and an object of the present invention is to reliably support the head and cervical vertebrae at a stable height position and to follow the shape of the head. An object of the present invention is to provide a pillow that can be recessed so as to envelop the part and allow an ideal head to fit at bedtime.

In order to achieve the above object, the pillow according to the present invention, as described in claim 1, has an outer diameter smaller than the thickness of the pillow body filled with the stuffing in the pillow body filled with the stuffing, and Two cylindrical inner bags filled with stuffing are arranged in parallel to each other at a predetermined interval in the width direction of the pillow body, and at one side in the intermediate portion of the pillow body in the width direction. An inclined partition cloth extending obliquely from the upper side of the cylindrical inner bag body toward the lower side of the other cylindrical inner bag body is provided, and the pillow body is provided with the cylindrical inner bag body by the inclined partition cloth, respectively. In the pillow partitioned into two stuffing chambers, the pillow body has one end in the longitudinal direction of the rectangular fabric on the upper surface at the center of the fabric and the other end on the lower surface at the center of the fabric. On the fabric so that one end and the other end of the fabric overlap each other Yes by sewn to the ground, characterized in that the fabric between the sewn portions for the fabric of the one end and the other end of the fabric is formed on the inclined partition cloth.

In the pillow configured as described above, the invention according to claim 2 is provided between the upper surface side inner surface of the pillow body and the upper peripheral portion of the cylindrical inner bag body, and between the lower surface side inner surface of the pillow body and the cylindrical inner bag body. An upper and lower stuffing layer is provided between each of the upper and lower perimeters.

  According to the first aspect of the present invention, in the pillow body filled with the stuffing, two cylinders whose outer diameter is smaller than the thickness of the pillow body filled with the stuffing and in which the stuffing is filled. Since the inner bag body is arranged in parallel with each other at a predetermined interval in the width direction of the pillow body, when the head is supported by this pillow, the cylindrical inner bag body has its diameter due to the load of the head. The inner filling of the cylindrical inner bag is intended to move in the radial direction and the length direction (left-right direction) of the cylindrical inner bag. The degree of freedom of the stuffing is restricted by the peripheral surface, and in particular, the downward dent resistance against the load increases, and the cylindrical inner bag body filled with these stuffing functions as the core material of the pillow. The cervical spine can be supported at a stable height by preventing excessive sinking.

  In addition, the padding layer existing between the upper peripheral surface of the cylindrical inner bag body serving as the core material and the inner surface on the upper surface side of the pillow body is thin, and the cylindrical inner bag body is formed between the lower peripheral surface and the pillow main body. Since it is firmly supported by the padding layer existing between the inner surfaces on the lower surface side and hardly moves downward, there is no risk that the cervical vertebra part will sink deeply, and a thin padding layer existing above the cylindrical inner bag body Can be stably held in the recessed portion. Furthermore, the head is supported in the intermediate part in the width direction of the pillow, that is, between the two cylindrical inner bags, and the padding that exists between the cylindrical inner bags is also the cylindrical inner bag. The body is prevented from greatly escaping in the width direction of the pillow, can form a dent along the shape of the head, can softly support the head, and allows comfortable sleep .

Further, the other cylindrical inner bag from the upper side of one cylindrical inner bag body in the two cylindrical inner bag bodies arranged in parallel in the pillow main body at the intermediate portion in the width direction in the pillow main body. An inclined partition cloth extending obliquely toward the lower side of the body is provided, and the pillow body is partitioned into two stuffing filling chambers each having the cylindrical inner bag body by this inclined partition cloth. A lower wedge-shaped chamber tapered toward the other cylindrical inner bag body is formed between the inclined lower surface of the inclined partition cloth and the inner surface of the lower surface side of the pillow body on the chamber side in which the inner bag body is installed. In addition, on the chamber side in which the other cylindrical inner bag body is installed, the taper is tapered toward the one cylindrical inner bag body between the inclined upper surface of the inclined partition cloth and the upper surface side inner surface of the pillow body. An upper wedge-shaped chamber is formed.

  Therefore, when the head is supported on the intermediate part of the pillow main body between these cylindrical inner bag bodies, the other padding in the upper wedge-shaped chamber is provided on the chamber side along the inclined upper surface of the inclined partition cloth. While being able to move easily while sliding toward the cylindrical inner bag body to cause a dent in the support portion of the head, in the lower wedge-shaped chamber, the padding is transferred from the wedge-shaped chamber to one cylindrical inner bag. Forms a support layer for the head while maintaining a state of biting into this wedge-shaped chamber with little movement to the body side, and therefore supports the head at an ideal height without causing the head to sink significantly. It is possible to form the concave portion in which the head is softly wrapped by the padding in the upper wedge-shaped chamber.

When the filling density of the fillings in the two cylindrical inner bags is higher than the filling density of the fillings in the pillow body, both cylindrical inner bags are made more rigid. The function as a core material can be exhibited, and the head and cervical spine portions can be supported more firmly and stably over a long period of time.

In addition, the support height of the cervical spine portion is selected according to preference by forming one cylindrical inner bag body filled with the stuffing with a large diameter and the other cylindrical inner bag body with a small diameter. Has the advantage that it can.

[Embodiment 1]
1 to 3 show Embodiment 1 of the pillow of the present invention. This pillow A1 includes a bag-shaped pillow body 1 filled with padding 2 such as buckwheat noodles, and the pillow body 1. The pillow body 1 is composed of two cylindrical inner bag bodies 3 and 4 which are filled with padding 2 'such as buckwheat noodles inside the pillow body 1 arranged in parallel with each other at a predetermined interval. Has been. 1 is a perspective view showing the internal structure of a part of this pillow A1, FIG. 2 is a perspective view of the whole pillow A1, and FIG. 3 is a part of the state in which the padding 2 in the pillow body 1 is removed. It is a notch perspective view.

  As shown in FIG. 4, the pillow body 1 is formed by sewing a fabric having air permeability and flexibility, preferably a high-density woven fabric, into a flat bag body having a flat horizontally long rectangular shape. The cylindrical inner bag bodies 3 and 4 formed in a flat cylindrical shape by the same material as 1 are disposed in parallel in the width direction of the pillow main body 1 with a certain interval therebetween, and these cylindrical inner bag bodies 3, 4 is integrally sewn to one end on the short side of the pillow body 1, and the stuffing 2 is placed in the pillow body 1 and the cylindrical inner bag bodies 3 and 4, respectively. After filling 2 ', the pillow A1 is formed by sewing the other ends of the cylindrical inner bag bodies 3, 4 to the other end of the pillow body 1.

  The lengths of the cylindrical inner bag bodies 3 and 4 are formed substantially equal to the length of the pillow body 1 (the width in the left-right direction), and the padding 2 'is more than the thickness of the pillow body 1 filled with the padding 2. The outer diameters of these cylindrical inner bag bodies 3 and 4 that are filled and formed into a cylindrical shape are formed to have a small diameter. There is a filling 2 filling. That is, between the upper surface side inner surface of the pillow body 1 and the upper peripheral portion of the cylindrical inner bag bodies 3 and 4, and between the lower surface side inner surface of the pillow body 1 and the lower peripheral portions of the cylindrical inner bag bodies 3 and 4. Between the upper and lower stuffing layers 21 and 22, there is a central stuffing layer 23 having a thickness corresponding to the thickness of the pillow body 1, between both cylindrical inner bag bodies 3 and 4, Outer padding layers 24 and 24 are also present between the cylindrical inner bag bodies 3 and 4 and the inner surfaces of both ends of the pillow body 1.

  Since it comprised in this way, the cylindrical inner bag bodies 3 and 4 which have filled the filling 2 'inside show the function as a core material of a pillow. That is, when a load to be compressed is applied to the cylindrical inner bag bodies 3 and 4 from above, the filling 2 ′ filled in the cylindrical inner bag bodies 3 and 4 is perpendicular to the circular cross section of the cylindrical inner bag bodies 3 and 4. Although the compression action is received, this compression action also acts in the direction in which the cross-sectional circle of the cylindrical inner bag bodies 3 and 4 is expanded and deformed in the horizontal direction. It is received by the inner peripheral surfaces of the bag bodies 3 and 4 and is compressed and deformed by receiving a resistance force that prevents deformation from the stuffing 2 in the pillow body 1 existing around the cylindrical inner bag bodies 3 and 4. Will be suppressed. Therefore, the length direction and the radial direction in the cylindrical inner bag bodies 3 and 4, in particular, the degree of freedom of movement of the stuffing 2 ′ in the radial direction is narrowed. In addition, the entire cylindrical inner bag bodies 3 and 4 are Since it is supported by the upper and lower stuffing layers 21 and 22 and both ends in the length direction are fixed to both ends of the pillow main body 1 by sewing, it exhibits almost no bending deformation and functions as a core material. It will be done.

  Therefore, the cervical vertebrae part is supported on one cylindrical inner bag body 3 with the length direction of the pillow body 1 directed in the left-right direction, and the widthwise center part of the pillow body 1, that is, both cylinders When the head is supported by the pillow main body part between the inner bag bodies 3 and 4, the cervical vertebra part sinks greatly downward by the cylindrical inner bag body 3 filled with the padding 2 '. The cervical vertebra portion can be supported at a stable height by the cylindrical inner bag body 3 while the padding layer 21 on the cylindrical inner bag body 3 is recessed along the shape of the cervical vertebra portion.

  Further, the central stuffing layer 23 between the cylindrical inner bag bodies 3 and 4 supporting the head receives a compressive force due to the load on the head, and the stuffing 2 of the central stuffing layer 23 is caused by the compressive force of the pillow. The tubular inner bag bodies 3 and 4 prevent the movement in the width direction, in other words, the escape in the width direction, and the part receiving the head is greatly recessed downward. Instead, a concave portion that can stably support the head at a certain height is formed along the shape of the head.

In the first embodiment, the other side from the upper side of one cylindrical inner bag body 3 to the intermediate portion in the width direction in the pillow body 1 is shown. An inclined partition cloth 5 extending obliquely toward the lower side of the cylindrical inner bag body 4 is provided, and the pillow main body 1 is filled with two paddings having the cylindrical inner bag bodies 3 and 4 respectively by the inclined partition cloth 5. It is divided into chambers 11 and 12. 6 is a perspective view showing the internal structure of a part of the pillow A3, FIG. 7 is a perspective view of the pillow A3 as a whole, and FIG. 8 is a partially cutaway view with the padding 2 in the pillow body 1 removed. It is a perspective view.

  The structure of the pillow A3 in the third embodiment will be described in more detail. As shown in FIG. 9, the pillow main body 1 is a fabric having air permeability and flexibility, preferably a high-density weave as in the first embodiment. The cylindrical inner bag bodies 3 and 4 formed in a flat cylindrical shape by using the same material as the pillow main body 1 are sewn in a flat bag body having a flat horizontally long rectangular shape. The upper inner surface of the cylindrical inner bag body 3 on the upper surface of the pillow body 1 is disposed between the cylindrical inner bag bodies 3 and 4 in parallel with a certain interval in the direction. An inclined partition cloth 5 sewn over the entire length is disposed on the inner surface of the lower side of the other cylindrical inner bag body 4 on the lower surface of the pillow main body 1, One end in the length direction of the cylindrical inner bag bodies 3 and 4 and the inclined partition cloth 5 is integrally sewn 8 to one end on the short side of the pillow body 1. And the other ends of the cylindrical inner bag bodies 3 and 4 and the inclined partition cloth 5 after filling the pillow body 1 and the inner cylindrical bag bodies 3 and 4 with the fillings 2 and 2 ', respectively. Is sewn 9 to the other end of the pillow body 1 to form a pillow A3.

  Accordingly, the pillow main body 1 has the padding filling chamber 11 in which one cylindrical inner bag body 3 is housed as described above by the inclined partition cloth 5 and the pillow main body 3 with respect to the one cylindrical inner bag body 3. 1 is divided into a stuffing filling chamber 12 in which the other cylindrical inner bag body 4 arranged in parallel with a certain interval in the width direction is provided, and in one chamber 11, an inclined partition cloth is provided. 5 is formed in a wedge-shaped chamber tapered toward the lower side of the other cylindrical inner bag body 4 between the inclined lower surface of the pillow body 1 and the inner surface of the lower surface side of the pillow body 1, and in the other chamber 12, It is formed in a wedge-shaped chamber tapered toward the upper side of one cylindrical inner bag body 3 between the inclined upper surface of the inclined partition cloth 5 and the inner surface on the upper surface side of the pillow body 1.

  The lengths of the cylindrical inner bag bodies 3 and 4 and the inclined partition cloth 5 are formed to be substantially equal to the length of the pillow body 1, and the padding is larger than the thickness of the pillow body 1 that is expanded by the filling of the padding 2. The outer diameters of the cylindrical inner bag bodies 3 and 4 that are expanded into a cylindrical shape by filling 2 'are formed to have a small diameter in the same manner as in the first embodiment. Upper and lower padding layers 21, between the inner periphery of the cylindrical inner bag bodies 3 and 4 and between the lower inner surface of the pillow body 1 and the lower peripheral portion of the cylindrical inner bag bodies 3 and 4, respectively. 22, and upper and lower wedge-shaped stuffing layers 23 a, 23 b having a thickness corresponding to the thickness of the pillow body 1 and partitioned by the inclined partition cloth 5 are present between both the cylindrical inner bag bodies 3, 4. Further, outer padding layers 24 and 24 are also provided between the cylindrical inner bag bodies 3 and 4 and the inner surfaces of both ends of the pillow body 1.

  FIG. 9 is an explanatory view of a method for producing the pillow body 1, in which one end 31 a in the length direction of a rectangular fabric 31 having a certain width and length is placed on the upper surface of the central portion 31 c of the fabric 31 and the other end. 31b is folded on the lower surface of the central portion 31c of the fabric 31. At that time, the end edges of these end portions 31a and 31b are overlapped with the upper and lower surfaces of the central portion 31c of the fabric 31 so that the end portions overlap each other by a certain length, and the end edges thereof are sewn to the fabric 31 respectively. To do. Accordingly, the inclined partition cloth 5 is formed by the central portion 31c of the cloth 31 between the two stitches 6,7.

  After that, the cylindrical inner bag bodies 3 and 4 sewn in a flat cylindrical shape in advance are inserted into the chambers 11 and 12 on both sides partitioned by the inclined partition cloth 5, and the insertion ends thereof are connected to the chambers 11 and 12. A constant interval in the width direction is maintained by sewing 8 one end opening edges of the chambers 11 and 12 together with one ends of the cylindrical inner bag bodies 3 and 4 while being interposed between the inner surfaces of the one end portions of the twelve ends. Then, the pillow body 1 formed by juxtaposing the cylindrical inner bag bodies 3 and 4 is sewn.

  Next, after filling these cylindrical inner bag bodies 3 and 4 and the chambers 11 and 12 with the fillings 2 and 2 'such as buckwheat, the other end edge of the opening of the filling filling chambers 11 and 12 is connected to the cylindrical inner bag body. The pillow A3 is manufactured by sewing 9 together with the other open end edges of 3 and 4. In addition, you may comprise so that the cylindrical inner bag bodies 3 and 4 and one opening end of the filling filling chambers 11 and 12 may be opened and closed freely with a fastener.

  According to the pillow A2 configured in this manner, in addition to the function and effect obtained by the first embodiment, the pillow body 1 and the filling filling chamber 11 in which one cylindrical inner bag body 3 is housed by the inclined partition cloth 5; The following effects are achieved by partitioning the other cylindrical inner bag body 4 into the stuffing filling chamber 12.

  That is, the cylindrical inner bag bodies 3 and 4 provided in the both stuffing filling chambers 11 and 12 exhibit the function as the core material as described in the first embodiment. The cervical vertebrae portion is supported on one cylindrical inner bag body 3 with the length direction directed in the left-right direction, and the central portion in the width direction of the pillow body 1, that is, both cylindrical inner bag bodies 3, When the head is supported by the pillow body part between the four, the cervical vertebra part is prevented from sinking downward greatly by the cylindrical inner bag body 3 filled with the stuffing 2 'inside. The cervical vertebra part can be supported at a stable height by the cylindrical inner bag 3 while the padding layer 21 on the inner sack body 3 is recessed along the shape of the cervical vertebra part.

  Further, the central stuffing layer 23 between the cylindrical inner bag bodies 3 and 4 supporting the head receives a compressive force due to the load on the head, and the stuffing 2 of the central stuffing layer 23 is caused by the compressive force of the pillow. The tubular inner bag bodies 3 and 4 prevent the movement in the width direction, in other words, the escape in the width direction, and the part receiving the head is greatly recessed downward. Instead, a concave portion that can stably support the head at a certain height is formed along the shape of the head.

  In this case, since the upper and lower wedge-shaped stuffing layers 23a and 23b partitioned by the inclined partition cloth 5 are present in the central portion of the pillow body 1, when the head is supported on the central stuffing layer 23, The upper wedge-shaped filling layer 23a moves toward the other cylindrical inner bag body 4 along the inclined upper surface of the inclined partition cloth 5 by the load, but the lower wedge-shaped filling layer 23b hardly moves and is wedge-shaped. A state in which the inclined partition cloth 5 and the lower surface of the pillow body 1 are clamped in the lower chamber is maintained, and therefore, a support layer for the head is formed by the lower wedge-shaped padding layer 23b. The upper wedge-shaped padding layer 23a causes a dent corresponding to the shape of the head due to the load on the head, so that the head is securely supported at an ideal height without being greatly depressed. be able to.

  In Embodiments 1 to 3 above, buckwheat porridge is used as paddings 2 and 2 ', but appropriate padding such as beads made of synthetic resin or strips made of an elastic material may be used. . The filling density of the filling 2 filled in the pillow body 1 and the density of the filling 2 'filled in the cylindrical inner bag bodies 3 and 4 are substantially the same, or the filling density of the cylindrical inner bag bodies 3 and 4 is the same. If the filling density of the stuffing 2 'in the stuffing 3 and 4 is made higher than the filling density of the stuffing 2 in the pillow body 1, the cylindrical shape of these can be obtained. The function of the inner bag bodies 3 and 4 as the core material of the pillow, that is, the function of suppressing the movement of the fillings 2 and 2 'and maintaining the stable support height of the cervical vertebrae part more reliably. In addition, the padding 2 'in the pillow body 1 having a low filling density has the advantage of being easily recessed by the load of the head and gently wrapping the head.

  When the pillow body 1 is divided into two filling filling chambers 11 and 12 each having the cylindrical inner bag bodies 3 and 4 by the inclined partition cloth 5, into the filling filling chambers 11 and 12. The filling density of the fillings may be different, or different kinds of fillings may be filled.
