Description

  The present invention relates to a pillow that is used with a head placed on the head during sleep or rest, and particularly to a pillow that can be easily adjusted in height.

  In general, the preferred height of pillows varies slightly from user to user, and even if that particular height is suitable for a particular user, the difference may be an unbearable difference for other users. is there.

  Therefore, in order to solve this, prepare various kinds of pillows with different heights so that the user can select the one that suits their preferred height, or the height By providing pillows that can be freely adjusted, it has been attempted to address such problems.

There are a number of proposals as an example of the latter.
One of them is a pillow (Patent Document 1) composed of a pillow body and a plurality of adjustment plates that are inserted into the pillow body to adjust the height.

  Although the pillow of this patent document 1 can adjust the height by inserting or extracting the adjustment plate in the pillow main body, it can perform the delicate height adjustment as described above. If it is going to do so, it is necessary to prepare many types of adjustment plates, for example, from a thin object to a thick one and insert them in combination. In addition, the actual height adjustment operation is a task that is determined by inserting and removing them and trying them. Looking at the example of this pillow, there are only two adjustment plates, so adjustment work is easy, but subtle height adjustment can not be expected, and the intended purpose is There is doubt whether it can be achieved. In any case, it is troublesome to prepare accessories such as an adjustment plate on the pillow.

  The second is a pillow in the shape of a horizontally long rectangular parallelepiped with a filling embedded therein, and a head seat that is located at substantially the center of the pillow and is in contact with the head seat. A side edge portion on which the head is not placed; and a tightening string attached to a boundary between the head seat portion and the side edge portion; The height of the head seat portion can be increased and the hardness can be adjusted tightly by tightening with the tightening string so that the packed material does not return to the side edge portion side. It is a pillow (patent document 2).

  Compared with the pillow of Patent Document 1, the pillow of Patent Document 2 can be finely adjusted in height depending on how the filler is moved, and there is no accessory such as an adjustment plate. Convenient for handling. However, in order to maintain the height of the head seat in that state after moving the filling, it is necessary to prevent re-movement due to the return of the moved filling, etc. There seems to be a problem. That is, in this pillow, re-moving due to the return of the filling or the like is intended to be prevented by tightening with a tightening string arranged at the boundary between the head seat portion and the side edge portion. Prevention seems to be less successful than this. When the pillow is tightened at the boundary, the cross-sectional area of the continuous part with both sides is only small, and the continuous state is not interrupted, so it gradually moved during use and adjusted with great effort The height may not be reliably maintained.

JP-A-2005-52210 JP 2002-65432 A

  The present invention solves the above-mentioned problems of the prior art, and can easily finely adjust the height without using any accessory, and can reliably maintain the height state, and has an appropriate elasticity. It is an object of the present invention to provide a pillow that can easily bring the positional relationship between the position of the head and the human skeleton into a natural state when sleeping using this.

  1 of the present invention comprises a pillow bag in a horizontally long cylindrical shape closed at both ends, the upper surface side on which the head of the pillow bag is placed is an elastic stretchable sheet material, and the lower surface side is a non-stretchable cloth material, Further, each pillow bag is filled with a fluid granular filler less than 100% of its capacity, and the pillow bag is moved from one end side to the other end side of the granular bag. The one end side is folded to the lower side closer to the other end side, and the lower end of the one end side is detachably joined to the lower side closer to the other end side. is there.

  According to 2 of the present invention, in the pillow according to 1 of the present invention, the pillow bag is configured such that the lower surface on one end side of the pillow bag can be detachably joined to the lower surface facing the other end side of the pillow bag. The first planar fastener along the one end is attached to the lower surface of one end of the two, and two or more second planar fasteners extending in the direction of the other end from the vicinity of the one end near the other end, A second planar fastener detachably engageable with the first planar fastener along the one end is attached.

  3 of the present invention is a partition piece for partitioning the length direction of the pillow according to 1 or 2 of the present invention at a position closer to the one end side inside the pillow bag, The partition piece which couple | bonded only the edge of the both sides with the cloth material and sheet material which comprise this pillow bag is arranged.

  Therefore, according to the pillow of the first aspect of the present invention, a desired amount of the granular filler in the pillow bag is moved to the other end side by lifting one end side, and the one end side is folded downward, If it is bonded and fixed to the lower surface on the other end side from the side portion, the height can be adjusted to a desired height. Since the amount of movement of the granular filler toward the other end can be set freely, the height can be finely adjusted. In addition, this height adjustment is actually performed while placing the head on the pillow and checking its sinking condition. Since the sinking height becomes a substantial pillow height at the time of sleeping, this height is adjusted to a desired height.

  According to the pillow of 1 of the present invention, since the upper surface side is made of a resilient and elastic sheet material as described above, as described above, when the head is put on this at the time of going to bed, The placed part sinks due to the weight or the like, but the height is maintained at a height balanced with the weight by the elasticity of the sheet material. In addition, if the head and the body are positively moved so as to be in a desired state while placing the head on the pillow, the state of the sinking becomes more appropriate. If the desired degree of sinking is not achieved, the amount of movement of the internal granular filler may be finely adjusted as described above. Thus, in this pillow, the head is elastically supported, and even when the head changes direction due to turning over, etc., and the weight on the pillow changes, the above-described operation of the user is performed. By adding a small amount, the height of the pillow can be easily changed to a balanced position accordingly, and the position of the head with respect to the human skeleton is stabilized at a predetermined position. The head always settles at the proper height and position.

  According to the pillow 2 of the present invention, it is possible to easily and reliably join and fix the one end side folded downward when adjusting the height of the pillow to the lower surface near the other end regardless of the folded length. Moreover, joining can also be cancelled | released easily.

  According to the pillow of 3 of the present invention, the upper edge of the partition piece and the sheet material on the upper surface side are not coupled to each other, so that the space between them is enlarged using the elastic elasticity of the sheet material, It is possible to move the granular fillers in the two compartments divided by the partition piece and freely adjust the filling ratio between the two compartments. Usually, of the two sections partitioned by the partition piece, the longer section, i.e., the section on the other end side is used to put the head on this when sleeping, as described above The height can be appropriately adjusted by adjusting the filling rate of the granular filler.

  One end side of the short section can be folded back to the other end side and joined to the lower surface on the other end side as described above when the granular filler is not filled in the section. Although it is possible to turn back even when there is a filling of the granular filler material in a short section, in many cases, it is inappropriate from the viewpoint of height adjustment.

  The pillow according to the present invention has a horizontally long cylindrical pillow bag configured with an elastic stretchable sheet material on the upper surface on which the head is placed and a non-stretchable fabric material on the lower surface side. Flowable granular filler that fills less than 100%, removable when the lower face on one end of the pillow bag and the lower face closer to the other end face the latter folded back It is comprised with the means comprised so that joining was possible.

  If the pillow is filled with a granular filler, it is in the shape of a horizontally long cylinder that is the shape of a pillow that is generally used. As described above, the sheet material that constitutes the upper surface of the pillow has elasticity and elasticity. Need to be This elastic stretchability is such that when the head is placed on the bed at the time of going to bed, an appropriate tension that can keep the sinking of the part at an appropriate height is provided. The material is not particularly limited. In addition, although it is preferable that it is a thing with a good touch, since it will normally be used covering a pillow cover, it does not become a problem so much.

  As the non-stretchable cloth material constituting the lower surface side of the pillow bag, a cloth material generally used for a pillow can be freely adopted.

  The pillow bag needs to be filled with an appropriate amount of a granular filler, and once filled, there is no particular need to open it, and the pillow bag may be completely closed. Moreover, the thing provided with the opening part which can be opened and closed in any site | part may be sufficient. In the latter case, it is appropriate to configure on the other end side. For example, it can be configured to be opened and closed with a fastener.

  As the granular filler, it is possible to employ various granular materials that are used for existing pillows and that can flow and move within the pillow bag. For example, buckwheat husks, rice husks, wood chips, synthetic resin beads, or beans can be used. Such a granular filler should be filled in an amount that is less than 100% of the capacity of the pillow bag, as described above. For example, 70 to 90% is appropriate, and more preferably around 80% should be adopted. The capacity of the pillow bag is a standard capacity in which the sheet material on the upper surface side is not expanded or contracted.

  Further, as means for detachably joining the lower surface on the one end side and the lower surface closer to the other end, various means capable of this can be adopted. For example, a first planar fastener extending along the one end is attached to the lower surface of the one end side, and two or more second planar fasteners extending from the vicinity of the one end toward the other end in a portion closer to the other end. Thus, a second planar fastener that can be detachably engaged with the first planar fastener along the one end can be attached. More specifically, the first planar fastener can be composed of a male planar fastener, and the second planar fastener can be composed of a female planar fastener.

  Furthermore, a partition piece that divides the length direction at a position closer to the one end side may be disposed inside the pillow bag. The ratio of the length or capacity of the one end side section and the other end side section is not particularly limited, but the range of the other end side section is used as a region on which the head is placed at bedtime. Therefore, the length or capacity at the other end should be taken into consideration. For example, it is appropriate for the length to be about the other end side: one end side = 8: 2. In this case, since the dimensions of the other portions are almost the same on either side, the capacity ratio is approximately this level.

  The said partition piece couple | bonds only the edge which contact | connects the lower surface side of a pillow bag, and the edge which contact | connects both sides with the cloth material and sheet material which comprise this pillow bag in the said position. The pillow bag is made into a pillow-shaped three-dimensional shape by filling the granular filler, but the partition piece is a cloth material and a sheet material that constitute the lower surface and both sides of the pillow bag in this state. That is, the edge part in contact with this is sutured. More specifically, the partition piece stitches all the edges in contact with the cloth material and only the edges in contact with both sides of the sheet material. Therefore, only the portion of the sheet material that constitutes the upper surface of the pillow-shaped pillow bag that is a pillow-shaped three-dimensional shape and the upper edge of the partitioning piece that is in contact with this is not sewn, and the elastic expansion and contraction of the sheet material When an operation such as pulling it away from the corresponding edge of the partition piece is added using the property, the space between them is expanded, and the granular filler filled in the compartment on one end side or the other end side is moved to the other side. It can be moved.

  An appropriate cloth material or the like can be used as the partition piece.

  Therefore, according to the pillow of the present invention, when the partition piece is not arranged inside, the desired amount of the granular filler in the pillow bag is moved to the other end side by simply lifting one end side or the like. The height can be adjusted to a desired height by folding the one end side downward and joining the portion on the one end side to the lower surface on the other end side. In addition, this height adjustment is actually performed while placing the head on a pillow and checking the degree of sinking. Since the sinking height becomes the substantial pillow height at the time of sleeping, this height is adjusted to a desired height. At this time, since the amount of movement of the granular filler toward the other end can be freely adjusted, the height can be finely adjusted.

  The above-described adjustment of the height of the pillow is performed by adjusting the folding length of one end side thereof, but as described above, the first planar fastener is arranged along the one end, and the second When the planar fastener is configured to have two or more strips extending from the vicinity of the one end toward the other end, the first planar fastener is elongated to the other end regardless of the folding length of the one end. It becomes possible to join and fix to any part of the extending second planar fastener, and can cope with height adjustment without any problem. Moreover, the joining is also easy and can be fixed reliably. Moreover, joining can also be cancelled | released easily.

  Further, according to the pillow of the present invention, the upper surface side is composed of a resilient and elastic sheet material as described above, and as described above, when the head is placed on this at the time of going to bed, The part placed due to the weight or the like sinks, but the height is generally maintained at a height balanced with the weight due to the elasticity of the sheet material. As described above, if the head and the body are positively moved so as to be in a desired state while the head is placed on the pillow, the sinking state becomes more appropriate. If the desired degree of sinking is not achieved, the amount of movement of the internal granular filler may be finely adjusted as described above. The same applies when turning over, and even when the head changes direction and the weight on the pillow changes, it is easier to add a slight amount of the user's motion as described above. Accordingly, the height of the pillow also changes to a balanced position, and the position of the head with respect to the human skeleton is stabilized at a predetermined position. The head always settles at the proper height and position.

  As described above, when the partition piece is arranged in the pillow bag, the part corresponding to the partition piece of the sheet material on the upper surface side of the pillow bag is moved away from the partition piece, and an appropriate gap is provided therebetween. The granular filler in the compartments on both sides is moved through this gap, the amount of the granular filler in the compartment on the other end side is adjusted appropriately, and the height of the pillow from the above viewpoint is adjusted appropriately. In this case, the height of the pillow can be adjusted appropriately in this way. When all the granular filler in the compartment on one end side is moved to the compartment on the other end side, it is convenient to fold the one end side to the lower surface on the other end side because the granular filler is difficult to return to the one end side. . The gap between the sheet material and the corresponding edge of the partition piece can be widened by pulling the corresponding part of the sheet material. For example, the sheet material extends downward and the gap widens due to the weight of the filled granular filler. In this state, the granular filler can be moved.

  As shown in FIGS. 1 to 4, the pillow according to the first embodiment has a horizontally long structure in which the upper surface side is made of elastic stretchable cloth material (sheet material) 1 a and the lower surface side is made of non-stretchable cloth material 1 b. A cylindrical pillow bag 1, a buckwheat shell (not shown) that fills the pillow bag 1, a male planar fastener (first planar fastener) 2 a disposed on the lower surface of one end of the pillow bag 1, and the pillow bag 1 is composed of two female planar fasteners (second planar fasteners) 2b and 2b extending from the vicinity of the one end to the other end.

  As shown in the figure, the pillow bag 1 is a horizontally long cylindrical bag body. As shown in FIGS. 2 and 4, the upper surface of the pillow bag 1 is made of elastic elastic material 1a and the lower surface thereof. The side is composed of a non-stretchable cloth material 1b, and the four surroundings except for a part on the other end side are sewn together. A part on the other end side is an opening 1c, and is configured to be freely opened and closed by a fastener. In the figure, 1d is a knob for opening and closing the fastener.

  In the first embodiment, the pillow bag 1 is formed into a bag body having a lateral length of 600 mm and a width of 300 mm without being filled with a filler and being crushed flat.

The elastic elastic cloth material 1a is literally a elastic elastic material, and chemical fibers having the following relationship between tensile load and elongation applied thereto were used.
Tensile load Elongation 1.0kg 30mm
1.5kg 60mm
2.0kg 85mm
3.0kg 100mm

This relationship is the result of measurement as follows.
As shown in FIG. 6, the cloth material 1a is cut into a width W of 300 mm and a length L of 450 mm to form a test piece S, and measurement auxiliary bars b1 and b2 are attached to both ends thereof. Then, the measurement auxiliary bar b1 at one end is fixed, and the spring h is disposed on the hook h arranged at the center of the measurement auxiliary bar b2 at the other end, and the measurement is performed while pulling.

  In this embodiment, the non-stretchable cloth material 1b is a cotton cloth used for a general pillow.

  The buckwheat husk is used as a fluid granular filler, and in this example, it was filled with an amount corresponding to 80% of the standard capacity of the pillow bag 1. The standard capacity refers to a capacity in a state where the cloth material 1a on the upper surface side is not expanded or contracted.

  As shown in FIGS. 1 to 3, the male planar fastener 2 a is a band-shaped member joined and fixed along one end on the lower surface side of the pillow bag 1. It consists of a large number of flexible hook members planted in a random direction. The female planar fasteners 2b and 2b extend from the vicinity of the male planar fastener 2a at one end on the lower surface side of the pillow bag 1 toward the other end as shown in FIGS. It is a fixed belt-like member, and is a thing made up of a belt-like base material sheet and a large number of flexible ring members planted in a random direction thereon.

  Therefore, according to the pillow of the first embodiment, the height can be easily adjusted and fine adjustment is also possible. In addition, when sleeping, the head placed on top of this is elastically supported, and when the head changes direction due to turning over and the weight on the pillow changes, the height of the pillow is balanced accordingly. The position of the head relative to the human skeleton is stabilized at a predetermined position. Of course, if the user moves the body and head slightly so as to settle at a desired position, the user can more effectively settle at the desired height position. The head always settles at the proper height. Furthermore, even if the height at which the head is supported is changed, the hardness of the pillow can be maintained substantially the same.

  When adjusting the height of the pillow, first, by lifting up one end side of the male planar fastener 2a, the buckwheat hull, which is a granular filler in the pillow bag 1, is moved to the other end side, Thereafter, one end of the pillow bag 1 is folded downward, and the male planar fastener 2a on the lower surface thereof is joined and fixed to the female planar fasteners 2b and 2b disposed on the lower surface closer to the other end.

  The height of the pillow is adjusted by the amount of movement of the buckwheat from one end to the other end. If you want to increase the height, move the corresponding amount of buckwheat from one end to the other. Although it is a good translation, usually, by moving as much amount as possible to the other end side in advance, when folding one end side of the pillow bag 1 downward, adjusting the folding length, It is appropriate to adjust the capacity of the pillow bag 1 to adjust its height.

  As described above, the height of the pillow is adjusted by adjusting the folded length on one end side where the male planar fastener 2a is arranged. As described above, the male planar fastener 2a is adjusted. And the two female planar fasteners 2b, 2b are extended from the vicinity of the male planar fastener 2a toward the other end, so that the male The die surface fastener 2a can be joined and fixed to any part of the length direction of the female die surface fasteners 2b, 2b extended to the other end side, and the above height adjustment can be handled without any problem. . Further, the joining and fixing can be performed easily and reliably, and the joining can be easily released.

  Moreover, according to the pillow of this Example 1, since the upper surface side is composed of the elastic stretchable cloth material 1a as described above, when the head is placed on this at the time of going to bed, FIG. As shown in the figure, the placed part sinks due to the weight and the like, but the height is maintained at a height balanced with the weight by the elasticity of the cloth material 1a. In addition, if the head and the body are positively moved so as to be in a desired state while placing the head on the pillow, the sinking state is adjusted to a more appropriate state and becomes the original sinking state. If the desired degree of sinking is not achieved, the amount of movement of the internal granular filler is finely adjusted as described above. When this pillow is used, the head is elastically supported as described above, and even when the weight of the head changes due to turning over, etc. By slightly adding such an operation, the height of the pillow can be easily changed to a balanced position accordingly, and the position of the head with respect to the human skeleton is stabilized at a predetermined position. The head always settles at the proper height and position.

  By the way, the human tibia is composed of seven vertebrae, and the normal shape is anteriorly curved. To support the anterior curvature of the cervical spine with a pillow at the position of the cranial spinal nerve located between the occipital region and the spine, the part corresponding to the posterior part of the pillow is made concave, and the part corresponding to the cervical spine is made convex However, as shown in the first embodiment, when the head is placed deeper on the pillow, the back of the head sinks in response to the pillow, and the part corresponding to the anterior curvature of the cervical spine It will swell and be able to support the anterior curvature of the cervical spine. This uneven shape of the pillow is determined according to the shape of each of the above parts of the user, and more appropriate support can be secured than the former type of pillow with a predetermined shape, It can be expected to have a therapeutic effect on diseases caused by cervical vertebral deformity as well as sleep.

  The pillow of this Example 2 differs from the pillow of Example 1 only in that the partition piece 3 is arranged inside the pillow bag 1, and the other points are completely the same. Therefore, only different points will be described, and description of other parts will be omitted.

  As shown in FIG. 7, the partition piece 3 is arranged in a state where the length direction of the pillow bag 1 is divided into two at a position closer to one end side. In the second embodiment, the partition piece is set so that the ratio between the length of the partition on the other end side and the length of the partition on one end side is set to the length of the partition on the other end side: the length of the partition on the one end side = 8: 2. 3 is arranged.

  The partition piece 3 is made of a cloth material made of the same material as the non-stretchable cloth material 1b constituting the lower surface side of the pillow bag 1, and is shown in bold lines in FIGS. 8 (a) and 8 (b). As shown, only the part contacting the lower surface side and both side parts of the pillow bag 1 out of the entire peripheral edge is stitched to the corresponding part of the pillow bag 1. That is, the partition piece 3 is not sewn to the pillow bag 1 only at the portion of the entire peripheral edge that is in contact with the central portion of the cloth material 1a on the upper surface side constituting the pillow bag 1.

  Therefore, according to the pillow of the second embodiment, the part corresponding to the partition piece 3 of the cloth material 1a on the upper surface side of the pillow is pulled up with a finger, for example, as shown in FIG. Then, there is a gap e between the upper edge of the partition piece 3 and the cloth material 1a on the upper surface side, and through this, the granular fillers (buckwheat husks) on both sides of the partition piece 3 are moved to the mutually opposite compartments. Can be made. In such a state where the gap e is positioned on the upper side, it is not easy to move the granular filler, so that the pillow is turned vertically while keeping the gap e. In this way, the side section to be the destination of the granular filler is set downward. In this way, when the section to be moved is moved downward, the granular filler filled in the upper section moves to the lower section through the gap e. In this way, the height of the pillow can be adjusted by appropriately adjusting the filling amount of the long section on the other end side of the granular filler.

  Further, as shown in FIG. 9, if the pillow is turned upside down, the original fabric material 1a on the upper surface side is positioned on the lower side, and the fabric material 1a is elastic and elastic as described above. Therefore, depending on the weight of the filled granular filler, it hangs downward. Therefore, there is a gap e between the upper edge of the partition piece 3 (lower edge in the state of this figure) and the facing part of the cloth material 1a, and the granular fillers in the compartments on both sides are opposite to each other through the gap e. Can be moved into the compartment. In this case, the pillow can be tilted so that the section to be moved is downward, and the granular filler in the upper section can be moved to the lower section side.

  In any case, the amount of the granular filler in the long section on the other end side can be adjusted to appropriately adjust the height of the portion on which the head is placed at bedtime.
