Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows a perspective view showing a state in which the sleeping posture holder 1 according to the present embodiment is attached to the mattress 2. The directions shown in FIG. 1 are the left-right direction as seen from the user when the user lies on his back on the mattress 2, and the front-back direction consisting of the front direction in which the user's head is located and the back direction in the direction in which the user's legs are located. The direction and the vertical direction perpendicular to the ground plane (not shown) on which the mattress 2 is placed flat, and the vertical direction, the horizontal direction, and the front-rear direction are orthogonal to each other. The same direction is appropriately applied to FIGS. 2 to 15.

The sleeping posture holder 1 is wound so as to go around the outer surface 3 of the mattress 2 having a substantially rectangular shape in a plan view along the direction of the short side 4 of the substantially rectangular shape (the left-right direction in this figure). Used for. The sleeping posture holder 1 is used when the user lies down on the mattress 2.

The sleeping posture holder 1 is extended in a substantially band shape along the winding direction (left-right direction in this figure), and is positioned at least under the user's waist in the wound state to resist the user's own weight. It has a rigid portion 5 with predetermined strength reinforcement.

In this figure, the sleeping posture holder 1 has an engaging portion 6 and an engaged portion 7, and the engaging portion 6 and the engaged portion 7 on the side portion 9 corresponding to the long side 8 of the mattress 2 having a substantially rectangular shape. Are engaged with each other. However, the engaging portion 6 and the engaged portion 7 may be engaged with each other, for example, on the bottom surface of the mattress 2 (the lower surface in this figure).

FIG. 2 shows a plan view of the sleeping posture holder 1.

The engaging portion 6 is provided on one side (leftward side in this figure) along the substantially strip-shaped extending direction (left-right direction in this figure) of the rigid portion 5 of the sleeping posture holder 1 and is engaged. The joint portion 7 is provided on the other side (right direction side in this figure) along the substantially strip-shaped extending direction with respect to the rigid portion 5, and is engaged with the engaging portion 6. In this figure, the engaging portion 6 has a shorter length in the left-right direction than the engaged portion 7, but the engaging portion 6 may be longer.

The engaging portion 6 includes a band member 12 and two hook-and-loop fasteners 13, and the engaged portion 7 includes a band member 12'and two hook-and-loop fasteners 13'. In this figure, the band member 12 and the band member 12'are grouped together at the left or right end so that the two rectangular rubber bands can be easily handled, but instead of the rubber band. A rubber band, another string, a cloth belt, a leather belt, or the like may be used, and the shapes of the band members 12, 12'are not particularly limited. Further, instead of the hook-and-loop fasteners 13 and 13', fasteners, hooks, buttons, hooks, rings and the like may be used.

The rigid portion 5 includes a base portion 10 extending along a first direction (left-right direction in this figure) parallel to the extension direction of the sleeping posture holder 1, and a plurality of rigid portions 11 arranged on the base portion 10. .. In this figure, eight rigid bars 11 are respectively extended along a second direction (front-back direction in this figure) orthogonal to the extension direction at the base 10, and are arranged side by side with each other in the first direction. ing. FIG. 1 shows an example in which eight rigid bars 11 are arranged, but in this figure, 16 rigid bars 11 are arranged. The number of rigid bars 11 may be larger or smaller.

The material of the base 10 is not particularly limited, but is composed of a fabric having hardness that can be used without the rigid bar 11, for example, a mesh fabric such as polyester having good breathability. The rigid bar 11 has, for example, a strip-shaped plate or a rod, and is made of a metal such as stainless steel or steel, or a resin such as an acrylic plate.

Each rigid bar 11 is appropriately sewn and fixed inside the base 10, for example, arranged in a pocket-shaped closed space provided in the base 10. As an example of a specific method, after each rigidity bar 11 is inserted from the opening 20 into the inside of the tubular portion 18 as shown in FIG. 13 described later, the opening 20 is closed to close the pocket described above. The rigid bars 11 can be arranged in the closed section.

FIG. 3 shows a plan view showing a state in which the user M lies on his back on the mattress 2 equipped with the sleeping posture holder 1.

The sleeping posture holder 1 is attached so as to be at least positioned under the waist portion 14 of the user M in a state of being wound around the outer surface 3 of the mattress 2.

In this figure, 16 rigid bars 11 are arranged in the rigid portion 5, and four of them are arranged under the waist portion 14 of the user M.

The size of the rigid portion 5 can be desired according to the physique of the user M and the size of the mattress 2.

The width of the rigid portion 5 in the left-right direction is substantially equal to the short side 4 of the mattress 2 in this figure so that the waist portion 14 can be supported even when the user M rolls over.

The width of the rigid portion 5 in the front-rear direction is preferably shorter than the long side 8 of the mattress 2. Since the weight of the user M is usually mainly applied to the waist 14 (about 44% of the whole) and the chest 21 (about 33% of the whole), the rigid portion 5 is provided under at least a part of the waist 14 and the chest 21 of the user M. It is preferably configured to be arranged.

FIG. 4 shows a conceptual diagram illustrating an example of how to attach the sleeping posture holder 1. The method of attaching the sleeping posture holder 1 includes, for example, steps (A) to (D).

First, in the step (A), the user M lifts the mattress 2 and lays the engaged portion 7 of the sleeping posture holder 1 under the mattress 2.

Next, in the step (B), the positions of the sleeping posture holder 1 and the mattress 2 are adjusted and shifted to a desired mounting position.

Then, in the step (C), the sleeping posture holder 1 is wound around the mattress 2 from above along the left-right direction.

In the step (D), the hook-and-loop fastener 13 provided on the engaging portion 6 and the hook-and-loop fastener 13'provided on the engaged portion 7 are engaged with each other on the side portion 9 on the long side of the mattress 2 on the right side of this figure. The attachment to the mattress 2 is completed.

<Effect of embodiment>
A plurality of types of mattresses 2 having various hardnesses are sold, but the one selected and purchased by the user M may be softer than expected. In such a case, when the user M actually lays down, the amount of dent or sinking due to the weight of the user M becomes larger than expected, resulting in an unnatural sleeping posture, which makes the lower back particularly uncomfortable. It may cause back pain.

In such a case, the sleeping posture holder 1 of the present embodiment is used by winding it around the outer surface 3 of the mattress 2. The sleeping posture holder 1 of the present embodiment has a rigid portion 5, an engaging portion 6, and an engaged portion 7, and is engaged with the engaging portion 6 after being wound as described above. By engaging with the joint portion 7, it is attached to the mattress 2 and its position is fixed.

Then, in the wound state in this way, the rigid portion 5 is located at least under the waist portion 14 of the user M. The rigid portion 5 is provided with a predetermined strength reinforcement against the weight of the user M so that the rigidity is higher than that of other portions (engaged portion 6, engaged portion 7, etc.). As a result, it is possible to suppress the unnatural sleeping posture of the user M due to the large dent or sinking of the mattress 2 as described above, and to maintain a comfortable sleeping posture for the user M. Therefore, it is possible to improve the sleeping comfort and prevent low back pain (improvement of low back pain and discomfort around the waist).

Further, in the present embodiment, in particular, when the engaging portion 6 and the engaged portion 7 are engaged with each other directly behind the mattress 2 (the outer surface of the bottom portion), for example, a new engagement is performed to the present embodiment. When the sleeping posture holder 1 is attached or when the sleeping posture holder 1 is disengaged and the sleeping posture holder 1 is removed, the mattress 2 must be lifted, shifted, or stood up, which imposes a heavy labor burden on the user M. .. In the present embodiment, by configuring the above engagement on the side portion of the mattress 2, the above-mentioned problems can be avoided and the labor burden can be reduced.

Further, in the present embodiment, in particular, the rigid portion 5 is configured by disposing a plurality of rigid bars 11 made of, for example, a metal, an acrylic plate, or other high-rigidity body with respect to the base portion 10. In this way, the rigid portion 5 can be manufactured inexpensively and simply by forming the rigid bar 11 that imparts rigidity and the other base portion 10 separately.

Further, for example, by appropriately adjusting the arrangement position and the number of arrangements of the plurality of rigidity bars 11, it is possible to cope with the difference in the waist position depending on the gender and physique of the user M and the preference of the degree of rigidity required by the user M. can do.

Further, in the present embodiment, in particular, the rigid bars 11 of the sleeping posture holder 1 are extended along the second direction, for example, and are arranged side by side in the first direction, which is similar to the waist corset (supporter). User M originally suffers from low back pain in order to exert the fixing effect of, but when sleeping with the corset on, breathability is poor and it is hot in summer, or when tightening is difficult and it interferes with bedtime, etc. It can be used as a substitute for a corset.

Further, in the present embodiment, in particular, the width of the rigid portion 5 in the first direction is substantially equal to the short side 4 of the mattress 2, for example, so that the user M can turn over and the second rigid portion 5 can be turned over. The width in the direction is shorter than the long side 8 of the mattress 2, for example, the width is arranged under at least a part of the waist portion 14 and the upper arm portion 15 of the user M, so that the rigidity is provided only in a place desired by the user M. It can be raised and the other parts can be made softer.

Normally, bedding is used in the order of mattress 2, bed pad, and sheets. When the sleeping posture holder 1 is attached on the bed pad, the person can feel harder, and when the sleeping posture holder 1 is attached under the bed pad, the sleeping posture holder 1 can be felt more comfortably. The sleeping posture holder 1 may be attached to any position such as on the sheets. By such an operation, the sleeping comfort when the sleeping posture holder 1 is attached can be appropriately adjusted.

<Modification example>
The present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit and technical idea. Hereinafter, such a modification will be described.

(1) When the sleeping posture holder 1a includes a plurality of types of rigidity bars 11 to 11 ″ having different rigidity from each other FIG. 5 shows a perspective view showing a state in which the sleeping posture holder 1a of the modified example is attached to the mattress 2. The rigid portion 5a of the sleeping posture holder 1a includes a plurality of types of rigid bars 11 having different rigidity from each other, a rigid bar 11 ′, and a rigid bar 11 ″. In this figure, four rigid bars 11, two rigid bars 11', and two rigid bars 11 "are arranged in the rigid portion 5a.

Here, the rigidity bar 11 having the relatively lowest rigidity is referred to as medium, the rigidity bar 11 ″ having the highest rigidity is referred to as super hard, and the rigidity bar 11 ′ having an intermediate rigidity between 11 and 11 ″ is referred to as hard.

When the rigidity bars 11 to 11 "are made of stainless steel or steel, the rigidity can be adjusted by, for example, changing the thickness of the rigidity bars 11 to 11" or changing the compression ratio of the stainless steel or steel. When the rigidity bars 11 to 11 ″ are made of an acrylic plate, the rigidity can be adjusted by, for example, changing the thickness of the acrylic plate. In that case, the thickness of the acrylic plate is at least stepped on by a child from above, for example. However, it is preferable that the thickness is thick enough not to crack.

The rigidity of the rigidity bars 11 to 11 ″ may be different by a known method other than the above, and the material of the rigidity bars 11 to 11 ″ may be a material other than the above. In this figure, three types of rigidity bars 11 to 11 "with different rigidity are used, but more types may be used, and the number and arrangement of each of the rigidity bars 11 to 11" can be changed to desired ones.

FIG. 6 shows a plan view showing a state in which the user M lies on his back on the mattress 2 equipped with the sleeping posture holder 1a. In this figure, four rigid bars 11 ″ (super hard) are arranged under at least the waist portion 14 of the user M in the rigid portion 5a, and two rigid bars 11 ′ (hard) are arranged on the outside thereof in the left-right direction. On the outside thereof, four rigid bars 11 (medium) are arranged in each of the left and right directions.

FIG. 7 shows a conceptual diagram showing a state in which the user M has turned over. In this figure, when the user M rolls over to the left and turns sideways, for example, the rigidity bar 11 (medium) is arranged under the upper arm portion 15 of the user M.

This modification also has the same effect as that of the embodiment. Further, in this modification, by preparing rigidity bars 11 to 11 ″ of a plurality of types of rigidity (hardness) such as “super hard”, “hard”, and “medium”, the gender, physique, and preference of the user M can be determined. It is possible to respond in detail to differences in sleeping posture.

Further, for example, a rigid bar 11 ″ located under the waist 14 in a sleeping posture lying on his back and under the upper arm 15 (or shoulder) instead of the waist 14 in a lying posture lying down after turning over. It is also possible to provide a difference in rigidity between the position of the rigidity bar 11 (for example, in the case of sideways orientation, if the upper arm portion 15 or the waist portion 14 / under the shoulder is highly rigid, it may be hard and uncomfortable to sleep. (Weakens the rigidity of the rigidity bar 11). In this case, the change in sleeping posture as described above (sleeping posture in which more weight is applied to the waist 14 → sleeping posture in which more weight is applied to the upper arm 15 or shoulder instead of the waist 14). ), More fine adjustment is possible.

(2) When the cloth belt 16 is used for the engaging portion 6'and the engaged portion 7', FIG. 8 shows a perspective view showing a state in which the sleeping posture holder 1b is attached to the mattress 2. The engaging portion 6'and the engaged portion 7'of the sleeping posture holder 1b each include two cloth belts 16, and are engaged with the cloth belt buckle 17 connected to the end of the engaging portion 6'. The ends of the portion 7'are engaged. In this figure, the cloth belt 16 made of mesh cloth is used, but a leather belt may be used.

This modification also has the same effect as that of the embodiment. Further, since the cloth belt 16 is excellent in terms of hardness, if a rubber band or a rubber string is used for the engaging portion 6 and the engaged portion 7 as described above as the band member 12, there is a concern that the rubber is too soft. When the strength is not good, it is preferable to use the cloth belt 16 like the engaged portion 6'and the engaged portion 7'.

(3) When the size of the rigid portion 5f is large FIG. 9 shows a perspective view showing a state in which the sleeping posture holder 1c is attached to the mattress 2. The width of the rigid portion 5f and the rigid bar 11d of the sleeping posture holder 1c in the second direction (front-back direction in this figure) is wider than that in FIG. Further, the engaging portion 6 "and the engaged portion 7" of the sleeping posture holder 1c are provided with one band member 12a and 12b, respectively, and each end is provided with three hook-and-loop fasteners 13a and 13b. By engaging the hook-and-loop fasteners 13a and 13b, the engaging portion 6 ″ and the engaged portion 7 ″ are engaged. Only one hook-and-loop fastener 13a and 13b may be arranged, for example, in a larger shape.

This modification also has the same effect as that of the embodiment. Further, since the sleeping posture holder 1c has a wide width in the second direction (front-back direction in this figure) of the rigid portion 5f and the rigid bar 11d, even when the user M has a large physique, the lower part of the waist portion 14 is included. It is possible to increase the rigidity of the desired portion.

(4) When a plurality of sleeping posture holders 1 are used FIG. 10 shows a perspective view showing a state in which a plurality of sleeping posture holders 1a are attached to the mattress 2. In this figure, two sleeping posture holders 1a are mounted side by side in the front-rear direction of the mattress 2. In this figure, two sleeping posture holders 1a having the same rigidity distribution are arranged side by side, but those having different rigidity distributions (for example, the sleeping posture holder 1 and the sleeping posture holder 1a) may be arranged side by side.

According to this modification, when it is desired to widen the region of the rigid portion 5 on the mattress 2 according to the preference or request of the user M, for example, when it is desired to increase the rigidity of the entire mattress 2, the region of the rigid portion 5 is widened. Can be done. It can also be used when the size of the mattress 2 is large or when one mattress 2 is used by a plurality of people. Further, this modification also has the same effect as that of the embodiment.

(5) When the rigid bars 11a and 11b are arranged in a staggered manner FIG. 11 shows a plan view of the sleeping posture holder 1d. The plurality of rigid bars 11a and 11b provided on the rigid portion 5b of the sleeping posture holder 1d are arranged in a second direction (front-back direction in this figure) orthogonal to the extension direction (horizontal direction in this figure) at the base 10. They are extended along the same direction and are arranged in a staggered manner in the second direction with respect to the base 10.

That is, in this figure, an array in which two rigid bars 11a having a relatively short length in the second direction are arranged side by side in the second direction and a rigid bar 11b having a relatively long length in the second direction are arranged in the second direction. One array is arranged alternately in the first direction.

According to this modification, the rigidity distribution can be adjusted more finely by arranging the staggered arrangement without being particular about arranging the plurality of rigidity bars 11 in a row in the first direction or the second direction. In this staggered arrangement, if the rigidity of each of the rigidity bars 11a and 11b is further different, the variation of the desired rigidity distribution can be further expanded. Further, this modification also has the same effect as that of the embodiment.

(6) When the rigid bar 11c extends in the first direction FIG. 12 shows a plan view of the sleeping posture holder 1e. A plurality of rigid bars 11c are extended in the rigid portion 5c of the sleeping posture holder 1e along the first direction (left-right direction in this figure) at the base 10, and are mutually extended in the second direction (in this figure). They are arranged side by side in the front-back direction). In this figure, a predetermined space is provided between the rigid bars 11c in the first direction, and the rigid bars 11c are arranged in three groups g1 to g3 in the left-right direction. ..

This modification also has the same effect as that of the embodiment. Further, an example of such an arrangement of the rigidity bars 11c is one of variations for obtaining a desired sleeping comfort and rigidity distribution.

(7) When the Rigid Bar 11 is Attached to and Replaceable on the Base 10'FIG. 13 shows a conceptual diagram showing an example of a method for attaching and detaching the Rigid Bar 11 to the base 10'. In the rigid portion 5d of the sleeping posture holder 1f, the base portion 10'includes a plurality of tubular portions 18 into which a plurality of rigid bars 11 can be inserted and removed. For example, the tubular portion 18 is engaged with the mesh fabric of the base portion 10'by three sewing portions 19 in this figure, and has an opening 20 at the end portion in the first direction (left-right direction in this figure). The user M himself can insert and remove the rigid bar 11 into the opening 20 of the tubular portion 18 to attach or replace the rigid bar 11. Although not shown, a pocket lid made of, for example, a mesh cloth is provided near the opening 20, and the pocket lid is folded into the cylinder 18 by a method according to the matching method of the pillow case to close the opening 20. Alternatively, the rigid bar 11 is fixed to the cylinder portion 18 by a method such as providing a surface fastener or a button that can be engaged with the cylinder portion 18 on the pocket lid to close the opening 20. The opening 20 closed by such a method can be opened and closed at any time by the user M, and the rigid bar 11 can be replaced.

FIG. 14 shows a conceptual diagram illustrating a method of attaching the sleeping posture holder 1f to the mattress 2. The mounting method includes steps (A') to (D'). Strictly speaking, the sleeping posture holder 1f is completed in the step (D') of attaching the rigid bars 11 and 11', but for convenience of explanation, the sleeping posture holder 1f is also referred to as the sleeping posture holder 1f in other steps.

First, in the step (A'), the engaged portion 7 of the sleeping posture holder 1f is laid under the mattress 2. In FIG. 4, the rigidity bar 11 is fixed to the base 10 in advance, but the rigidity bar 11 of the base 10'is not provided.

Next, the mattress 2 and the sleeping posture holder 1f are adjusted to desired positions in the step (B').

Next, in the step (C'), the sleeping posture holder 1f is wound around the mattress 2 in the left-right direction.

In the step (D'), the hook-and-loop fasteners 13 and 13'of the engaging portion 6 and the engaged portion 7 are engaged with each other, and the sleeping posture holder 1f is attached to the mattress 2. After that, the desired rigidity bar 11 is attached to the cylinder portion 18 (not shown) of the base portion 10 ′. In this figure, two rigid bars 11 and one rigid bar 11'are attached, but if the desired number of rigid bars 11 to 11 "are attached as needed, the sleeping posture holder 1f is attached. Is completed, and the installation of the sleeping posture holder 1f is completed.

This modification also has the same effect as that of the embodiment. Further, in this modification, the rigidity bar 11 can be replaced, so that the user can wear it when he / she wants to further improve the feeling after using it once, or when he / she wants to change the distribution of rigidity due to a change in physique or the like. The rigid bar 11 can be removed and replaced with another rigid bar 11'to 11 ", etc. In addition, the manufacturer / distributor can make the base 10 and the rigid bar 11 an optional type sold separately. Is also possible.

(8) When the base portion 10 ″ is the rigid portion 5e FIG. 15 shows a perspective view showing a state in which the sleeping posture holder 1 g is attached to the mattress 2. The rigid portion 5e of the sleeping posture holder 1 g is from only the base portion 10 ″. It is configured and does not include the rigid bar 11. The base 10 ″ is configured by using, for example, a thick or high-strength cloth material having a higher rigidity than the cloth used for sheets, bed pads, etc., or by increasing the rigidity of the base 10 ″ by a sewing method or the like. Will be done.

Also in this modification, as in the embodiment, by arranging the mattress under the waist 14 of the user, the mattress 2 sinks only under the waist 14 to improve the unnatural sleeping posture and prevent (prevention) back pain. ) Or has the effect of alleviating the existing low back pain (alleviating the discomfort of the lower back 14).

(9) Others In the above, the band members 12, 12'and the like are not uniformly manufactured of the same material, but in, for example, a shadow portion (a portion hidden by the bottom surface of the mattress 2) that is difficult for the user to see. May reduce the manufacturing cost of the entire band member by making it thinner or making the dimensions smaller than the other parts or by using a cheap material.

Further, in the above description, when there is a description such as "vertical", "parallel", "planar", etc., the description does not have a strict meaning. That is, these "vertical", "parallel", and "planar" mean "substantially vertical", "substantially parallel", and "substantially flat", with design and manufacturing tolerances and errors allowed. ..
