Description

  The present invention is an improvement of a pillow that has a partition wall in a pillow case and is used by filling a flowable granular medium, and the flow of the granular medium near the neck support portion due to the weight of the head and neck The present invention relates to a pillow having an inclined partition wall that can be adjusted.

  Conventionally, as disclosed in Patent Document 1, a patent applicant discloses a pillow having an inclined partition wall as a pillow whose height and shape change in response to a user placing his / her head or neck.

  Although the central auxiliary partition wall in the vicinity of the neck support portion shown in Patent Document 1 has the trapezoidal partition wall inclined downward toward the neck side, the upper base and the lower base are in the laterally long direction of the upper surface fabric and the lower surface fabric, respectively. It is a straight stitch. Therefore, when the head and neck are placed on the pillow having the central auxiliary partition wall from the central neck support portion toward the head support portion, the inner granular material flows from the center to the left and right side portions. . If the flow of the granular intermediate material is too small, the neck position becomes too high, and if it is too much, the neck position becomes too low.

  The flow of the granular medium must be an appropriate amount. However, in the pillow having the central auxiliary partition wall shown in Patent Document 1, it has been impossible to adjust the flow of an appropriate amount of the granular intermediate material. In many cases, the flow of the granular intermediate material to the left and right side portions is too much, and the neck support portion tends to be lowered. This is the first problem.

  Furthermore, when turning over and using the pillow sideways, the head is positioned on the right or left side of the pillow that is shifted to the right or left from the center in order to lie down on the body. As a result, the weight of the head and neck is also applied to the sides. The granular intermediate material on the side portion is pushed and flows toward the central neck support portion. If it flows, its side will be lowered.

  The pillow is central, i.e. the head support and neck support are lower than the left or right side, and when using the pillow sideways, the left or right side is not higher than the head support and neck support. I can't get it. However, the pillow having the central auxiliary partition wall disclosed in Patent Document 1 cannot adjust the flow of the granular intermediate material from the side portion to the neck support portion, resulting in the backflow of the granular intermediate material, The side part would be lowered. Therefore, the problem that the appropriate height of a side part cannot be maintained has arisen. This is the second problem.

  Furthermore, even if the proper shape and height of the neck support portion are secured by the appropriate amount of granular intermediate material while lying on its back, the pillow having the central auxiliary partition wall shown in Patent Document 1 can be turned over. When the head and neck are shifted to the left or right side of the pillow by hitting, the granular intermediate material flows from the left or right side to the neck support. As a result, there is a problem in that the proper shape and height of the neck support portion collapse. This is the third problem.

Japanese Patent Laid-Open No. 2010-69202

  Therefore, even when both sides of the inclined partition wall forming the neck support part are bent toward the shoulder position of the user and the head and neck are placed on the center of the pillow while lying on their back, a large amount of granular material is present. It suppresses flowing to the side part, solves the first problem, and secures the neck support part at the height of the user. Further, the leg portions of the trapezoidal inclined partition wall are used as free sides in order to allow a moderate amount of the granular intermediate material to flow to the left and right sides.

  Furthermore, the presence of the flow control piece by bending the flow control piece having a free side that becomes the flow path of the granular intermediate material between the side part and the neck support part toward the shoulder position of the user at an obtuse angle. In combination with the slanted partition wall being inclined downward on the neck side, the surface of the flow adjusting piece is inclined at an obtuse angle so that the granular medium tends to flow toward the side, and conversely toward the neck support part The granular intermediate material has an acute angle so that it is less likely to flow in comparison with the flow toward the side.

  As a result, even if you turn over and use the side of the pillow sideways, the amount of granular material flowing from the side to the neck support is reduced, and the height of the side is secured. The second problem is solved. Further, by reducing the flow amount, the neck support portion having an appropriate height is left, and the third problem is solved.

In order to solve the above-mentioned problems, the first invention employs the following means for a pillow having an inclined partition wall.
1stly, it is the pillow which fills and uses the flowable granular inside material in a pillow case, Comprising: It is set as the pillow which has the inclination partition wall of a neck support part in the neck side of a user near the center of a pillow case.
Secondly, the inclined partition wall of the neck support portion has a substantially trapezoidal shape whose upper base is shorter than the lower base.
Third, all the sides of the upper base are sewn to the upper surface fabric of the neck support portion substantially parallel to the lateral direction of the pillow case, and the middle of the lower base is slightly outside the position corresponding to the left and right end points of the upper base. The center part between the positions is sewn to the lower surface fabric at a position closer to the neck side so that the inclined partition wall of the neck support part is inclined downward on the neck side, and substantially square with the upper bottom, The part is formed as a flow blocking piece.
Fourth, the left and right substantially triangular portions from the line connecting both ends of the upper base and both ends of the central portion toward the left and right ends of the inclined partition wall of the neck support portion are obtuse in the direction of the shoulder position of the user. The bottom of the substantially triangular part is sewn to the lower fabric so that both ends of the bottom of the substantially trapezoidal shape reach the vicinity of the neck side end of the pillow case, and the left and right substantially trapezoidal leg parts flow as free sides. An adjustment piece is formed.

The second invention employs the following means for a pillow having an inclined partition wall.
1stly, it is the pillow which fills and uses the flowable granular inside material in a pillow case, Comprising: The inclination partition wall of a neck support part on the user's neck side in the vicinity of the center of a pillow case, A pillow having an inclined partition wall having an inclined partition wall of the head support portion in a direction opposite to the neck support portion in the vicinity of the center.

Secondly, the inclined partition wall of the neck support part has a substantially trapezoidal shape with the upper base shorter than the lower base, and the entire upper base is sewn to the fabric of the upper surface of the neck support part substantially parallel to the lateral direction of the pillow case. The middle part of the lower base, which is between the middle positions slightly outside the positions corresponding to the left and right end points of the upper base, is positioned closer to the neck so that the inclined partition wall of the neck support part tilts downward on the neck side. The bottom fabric at the position is stitched substantially parallel to the upper bottom to form a central rectangular portion as a flow-inhibiting piece, and the neck support portion from the line connecting both ends of the upper base and both ends of the central portion . The left and right substantially triangular portions facing the left and right ends of the inclined partition wall are bent at an obtuse angle toward the user's shoulder position, and both lower ends of the substantially trapezoidal shape are near the neck side end of the pillow case. Sew the bottom of the approximately triangular part to the bottom fabric so that the left and right approximately trapezoidal leg parts Forming a flow adjusting pieces as sides.

  Third, the inclined partition wall of the head support portion is an inclined surface that opens from the upper fabric side to the lower fabric side, and on the neck side, the inclined partition wall of the head support portion is inclined to the neck support portion. It is stitched between the upper surface fabric and the lower surface fabric at a position away from the partition wall.

  The present invention prevents flow of the granular intermediate material to the head support portion by forming a flow blocking piece on the inclined partition wall of the neck support portion, prevents the neck support portion from becoming too low, and adjusts the flow. By forming a piece, when lying on its back and placing the head and neck on the center of the pillow, a moderate amount of granular intermediate material flows from the free side of the flow adjustment piece to the left and right sides, and the low It becomes the neck support part. Also, even if you turn over and use the side part of the pillow sideways, the flow adjustment piece becomes an obstacle, and the amount of granular material flowing from the side part to the neck support part is reduced. The pillow has an inclined partition wall that can secure the height of the side portion and can leave a neck support portion having a proper low height.

  Although it is an effect of 2nd invention, while maintaining a neck support part at appropriate lowness, a head support part can also be made to maintain appropriate lowness, and the shape of an ideal pillow which has a smooth hollow Was able to produce.

Hereinafter, embodiments of the present invention will be described together with examples according to the drawings.
FIG. 1 is an explanatory plan view showing an embodiment of a pillow having an inclined partition wall, and FIG. 2 is an explanatory bottom view thereof. Reference numeral 1 in the figure denotes a pillow having an inclined partition wall, and the pillow 1 having an inclined partition wall is composed of a pillow case 2, an inclined partition wall 3 of a neck support portion existing in the pillow case 2, and an inclination of a head support portion. The partition wall 4, the left and right auxiliary partition walls 5, 5 ′, and the granular intermediate material 6 filled in the pillow case 2. The granular intermediate material 6 is indicated by hatching in FIG.

  As shown in FIG. 8, the pillow 1 having an inclined partition wall includes a neck support portion 12 formed by an inclined partition wall 3 of the neck support portion on the neck side of the user near the center of the pillow case 2, and a pillow case. A head support portion 11 formed by an inclined partition wall 4 of the head support portion in a direction opposite to the neck support portion in the vicinity of the center within 2, and side portions 13 positioned on the left and right sides of the head support portion 11 and the neck support portion 12, 14 is formed. In addition, the inclined partition wall 4 of the head support part and the inclined partition wall 3 of the neck support part are arranged at positions separated from each other.

  The granular intermediate material 6 is shown by the hatched portion in FIG. As the granular intermediate material 6, a resin chip, a wood chip such as a bag, a buckwheat husk, etc., which are materials that can flow in the pillow case 2 and are suitable for filling, are used. In the embodiment, a resin chip of a straw type pipe is used. A straw-type pipe having a thickness of 4.5 to 8 pie and a length of 5 to 8 mm is suitable. In the embodiment, a straw-type pipe having a thickness of 5.5 pie and a length of 6 mm is used.

  In the embodiment, the pillow case 2 is a three-dimensional sewing made of cloth, and as shown in FIG. 3, the upper surface fabric 21, the lower surface fabric 22, and the left and right side surface fabrics 23, 24 are stitched together. As shown in FIG. 8, the back surface of the pillow case 2 and the side fabric 24 are provided with granular intermediate material inlets 61 and 62. The pillow case 2 is manufactured by stitching one piece of fabric on the front surface including the upper fabric 21, the lower fabric 22, the front surface and the back surface. Only the side fabrics 23 and 24, the inclined partition wall 3 of the neck support portion, the inclined partition wall 4 of the head support portion, and the left and right auxiliary partition walls 5 and 5 'are made of individual fabrics. However, the present invention is not limited to this, and the upper surface, the lower surface, the front surface, and the back surface may all be independent individual fabrics and stitched together.

  The head support part 11 in the pillow case 2 in the embodiment is provided with an inclined partition wall 4 of the head support part. As shown in FIG. 4, the inclined partition wall 4 of the head support portion has a substantially U-shape in a plan view that is cracked in a direction opposite to the body side (neck side) of the user of the pillow case 2. ing. The U-shape is not strict, and ideally, the front side of the pillow 1 having an inclined partition wall (upper surface side) and the shape of the head support portion 11 gradually approaches the tip side so that it can follow the movement of the head. A shape that spreads widely is preferable.

  The inclined partition wall 4 of the head support part aims to maintain a certain low by surrounding the granular intermediate material 6 near the position where the head is placed. In the pillow 1 having an inclined partition wall, it is preferable that the head support portion 11 is lowest as compared with the other neck support portions 12 and the side portions 13 and 14. Further, the shape does not necessarily need to be a crack like a substantially U shape, and although it is not illustrated, a truncated cone-shaped inclined partition wall may be used. However, when such an inclined partition wall is used, it is necessary to separately form a granular intermediate material inlet in the lower surface fabric 22.

  The inner edge portion (upper end side portion) of the inclined partition wall 4 of the head support portion is sewn to the upper fabric 21 of the pillow case 2 and filled with the granular intermediate material 6. The head support portion 11 is formed to have a size that allows the user's head to be accommodated. On the other hand, the outer edge portion (lower end side portion) has a size suitable for obtaining a desired inclination and is sewn to the lower surface fabric 22 of the pillow case 2. The width of the inclined partition wall 4 of the head support portion determines the height of the inclined partition wall 4 of the head support portion when the head support portion is sewn inside the pillow case 2. The height of the inclined partition wall 4 is determined to be slightly lower than the distance between the upper surface fabric 21 and the lower surface fabric 22.

  Furthermore, the inclined partition wall 4 of the head support portion is sewn so as to be an inclined surface that opens from the upper surface fabric 21 side toward the lower surface fabric 22 side as a whole. In the embodiment, the inclination angle of the inclined partition wall 4 of the head support portion is 45 degrees, but it is desirable to incline within the range of 30 degrees to 60 degrees depending on the granular intermediate material 6 and other conditions.

  The inclined partition wall 4 of the head support portion has an upper end portion sewn to the inside of the upper surface fabric 21 and a lower end portion sewn to the inner side of the lower surface fabric 22. Furthermore, the opening end part 42 of the inclined partition wall 4 of the head support part is stitched inside the fabric on the back side of the pillow case 2 as shown in FIGS. 1 and 2. Thereby, the inner side of the inclined partition wall 4 of the head support portion is an independent partition space in the pillow case 2.

  In the embodiment, an inclined partition wall 3 of the neck support portion that forms the neck support portion 12 is provided on the neck side of the user from the head support portion 11 near the center in the pillow case 2. As shown in FIG. 7, the inclined partition wall 3 of the neck support portion has a substantially trapezoidal shape in which the upper base 34 is shorter than the lower base 35 in the unfolded state. In the embodiment, the length of the upper base 34 is about 18 cm, and the length of the lower base 35 is about 38 cm. In the inclined partition wall 3 of the neck support portion, the central square portion is the flow blocking piece 32 and the substantially triangular portions on both sides of the flow blocking piece 32 are the flow adjusting pieces 33 and 33 ′.

  6 and 7, reference numeral 36 in the inclined partition wall 3 of the neck support portion is a seam allowance for the upper bottom 34, and reference numeral 37 is a seam allowance for the lower bottom 35. In FIG. 6, reference numeral 38 denotes a reinforcing seam for the free side 39. The reinforcing seam allowance 38 is folded inward at a first folding line 40 (indicated by a chain line in FIG. 6), further folded inward at a second folding line 41 (indicated by a solid line in FIG. 6), and stitched. A reinforced free side 39 is shown in FIG. The reinforcing seam allowance 38 makes the free side 39 of the flow adjusting pieces 33, 33 'firm and prevents fraying of the fabric.

  All sides of the upper base 34 are sewn to the inner side of the upper fabric 21 at a seam allowance 36 so as to be substantially parallel to the lateral direction of the pillow case 2. An upper base 34 shown by a solid line in FIG. 1 is a stitched portion. A center portion of the lower base 35, that is, a position between the positions 53 and 54 slightly outside the positions corresponding to the left and right end points 51 and 52 (corner portions) of the upper base 34, is sewn to the lower surface fabric 22 using a seam allowance 37. . A lower bottom 35 indicated by a solid line in FIG. 2 is a stitched portion. The length between the left and right end points 51 and 52 of the upper base 34 is about 18 cm, while the length between the slightly outer positions 53 and 54 is about 24 cm. In this way, by increasing the length of the central portion of the lower base 35 that is sewn to the lower surface fabric 22 from the length of the upper base that is sewn to the upper surface fabric 21, the granular intermediate material 6 is placed in the pillow case 2. When the filling is performed, the stitched portion of the upper surface fabric 21 is pulled toward the lower surface fabric 22, and the neck support portion 12 can be made lower than the side portions 13 and 14.

  The inclined partition wall 3 of the neck support portion, specifically, the flow blocking piece 32 which is a central quadrangular portion is sewn so as to be inclined downward on the neck side. The lower bottom portion of the flow blocking piece 32 is stitched at a position closer to the neck side than the stitching position of the upper bottom 34. That is, the stitching position of the upper base 34 is the position of the top fabric 21 that is about 16 cm from the front end (neck end) of the pillow case 2 to the back (in the direction of the head support 11). The stitching position between the lower bottom portion constituting the portion 32, that is, between the slightly outer positions 53 and 54, is the position of the lower surface fabric 22 that is about 9 cm deeper than the front end of the pillow case 2. A portion surrounded by the stitched upper base 34 and the stitched lower bottom 35 is a flow blocking piece 32, and in particular, the granular intermediate material 6 is prevented from flowing from the neck support portion 12 to the head support portion 11 side. .

  The left and right side portions of the flow blocking piece 32, which is the central square portion of the inclined partition wall 3 of the neck support portion, are substantially triangular flow adjusting pieces 33 and 33 '. The flow control pieces 33 and 33 'are bent toward the user's neck. Since the flow adjusting pieces 33 and 33 'have a substantially triangular shape, the bottom side (the lower surface fabric 22 side) is wide and the apex side (the upper surface fabric 21 side) is narrow. Therefore, the granular intermediate material 6 located in the neck support portion 12 has very little flow on the lower surface fabric 22 side, and conversely, the flow on the upper surface fabric 21 side increases. Thereby, it can prevent that the neck support part 12 becomes extremely low, and when the weight is applied to the neck support part 12, appropriate flow is generated, and the neck support part 12 has a suitable height.

  The bending angle of the flow adjusting pieces 33 and 33 ′ is an obtuse angle with respect to the flow preventing piece 32. 100 degrees to 140 degrees is preferable. In the embodiment, the angle is 120 degrees. With this angle, the amount of flow from the neck support portion 12 to the side portions 13 and 14 of the granular intermediate material 6 is large, and the amount of flow from the side portions 13 and 14 to the neck support portion 12 is small. When the bending angle is 90 degrees, the flow amount of the granular intermediate material 6 is substantially the same.

  Since the inclined partition wall 3 of the neck support portion is inclined downward on the neck side, the flow adjusting pieces 33 and 33 ′ are also inclined downward on the neck side. The plane existing inside the bent state of the flow adjusting pieces 33, 33 ′ has a compound inclined surface that is lowered toward the neck and lowered toward the center of the neck support portion 12.

  The flow adjusting pieces 33, 33 ′ have a substantially triangular bottom portion (a lower bottom 35 portion of the inclined partition wall 3 of the neck support portion) sewn to the lower surface fabric 22. This bottom portion is about 7 cm in the embodiment. As this length increases, the flow control pieces 33 and 33 'increase and the flow rate of the granular intermediate material 6 decreases.

  In the embodiment, at this time, both end portions (both end portions of the lower bottom 35) of the flow adjusting pieces 33 and 33 ′ are on the neck end portion of the pillow case 2 (in the embodiment, the neck end portion of the lower surface fabric 22). However, it may be in the vicinity of the neck side end. In addition, the substantially triangular oblique side portions (the left and right leg portions of the inclined partition wall 3 of the neck support portion) of the flow adjusting pieces 33 and 33 ′ are free sides 39 that are not stitched to either the upper surface fabric 21 or the lower surface fabric 22. Has been.

  The left and right auxiliary partition walls 5, 5 ′ are not inclined but are vertical, but may be inclined rearward in the same manner as the inclined partition wall 3 of the neck support portion. The left and right auxiliary partition walls 5, 5 ′ restrict the flow of the granular intermediate material 6 in the front and rear directions (the front and rear direction toward the opposite direction from the user's neck side) at the side portions 13 and 14. When the pillow is used sideways, it is possible to prevent the unevenness in the side portions 13 and 14 of the granular intermediate material 6.
