Description

The present invention relates to bedding. In particular, the present invention relates to bedding that can reduce the pressure on the shoulders when turning over or lying down.

Conventionally, as seen in Patent Document 1, for example,
The purpose is to "eliminate, prevent, and provide a good night's sleep for shoulder disease problems," and "a pillow-integrated mattress that integrates a mattress and a pillow 5 is provided with hollow recesses 2 at positions corresponding to both shoulders, so that the shoulders when sleeping with the shoulders down are provided. A pillow-integrated protective shoulder mattress that eliminates pressure on the body is known (summary column of the same document, etc.).

However, in this pillow-integrated protect shoulder mattress, since the cavity recess 2 is provided over the entire length in the left-right direction, there is no part to support the neck when lying on one's back.
Therefore, there is a drawback that a large burden is applied to the neck when lying on one's back.

Japanese Laid-Open Patent Publication Nos. 2003-100002 and 2003-200003 also disclose bedding having a similar structure and drawbacks.

On the other hand, Patent Document 4, for example, discloses a body shape-adapting pillow dedicated to side sleep, in which a low-resilience material is incorporated in a hollow recess.
However, since the low-resilience material is also incorporated over the entire length of the hollow concave portion extending in the left-right direction, the portion that supports the shoulders when turning over or lying down and the portion that supports the neck when lying on the back are the same flexible. have sex.
Therefore, there is a problem that the pressure on the shoulder cannot be sufficiently reduced when turning over or lying down, and the burden on the neck when lying on one's back cannot be reduced.

In addition, in Patent Document 5,
"Bedding used at bedtime,
a pillow that supports the user's head, has cushioning properties, and is flexible and deformable;
a body seat portion that supports the user's body, has cushioning properties, and is flexibly deformable;
a connection portion made of a thin sheet material that connects the pillow portion and the main body sheet portion;
a pair of wall portions integrally disposed along the left and right side portions of the main body seat portion, having a greater thickness than the main body seat portion, a cushioning property, and a flexibly deformable rod-like wall portion;
The width dimension of the body sheet portion corresponds to approximately half the width dimension of the body portion of the user,
The left and right side ends of the pillow portion extend outside the left and right side ends of the connecting portion, and a space in which the connecting portion does not exist between the left and right side ends of the pillow portion and the wall portion. to form
The bedding for supporting lying posture, characterized in that the connecting part is sized so that the user's shoulders and upper arms can pass through toward one of the spaces.
(Claim 1 of the same document).

However, since the connection part 3 connecting the pillow part and the body sheet part of the sleeping posture support bedding is made of a thin sheet material, the thin sheet cannot effectively support the neck when lying on one's back.
Therefore, there is a drawback that a large burden is applied to the neck when lying on one's back.

An object of the present invention is to provide bedding that can reduce the pressure on the shoulders when turning over or lying down and can prevent a large burden on the neck when lying on one's back.

In order to solve the above problems, the bedding of the present invention is
Bedding having a concave portion into which the user's shoulders fit when the user lies down,
It has a neck support part that supports the user's neck from below when the user is lying on his or her back, and has shoulder relief recesses on both left and right sides of the neck support part, into which the user's shoulders can be inserted when the user is lying down. vinegar.

Since this bedding has the above structure, the following effects can be obtained.

When the user sleeps on this bedding, he/she can sleep with his/her neck resting on the neck support when lying on his or her back. Then, the neck support part supports the user's neck from below, so that the neck is not burdened.
In addition, when turning over or lying down, the user can turn over or lie down by inserting the shoulders into the shoulder relief recesses on the left or right side of the neck support. As a result, the pressure on the shoulders when turning over or lying down can be reduced.

As described above, according to this bedding, it is possible to reduce the pressure on the shoulders when turning over or lying down, and prevent a large burden on the neck when lying on one's back.

In this bedding,
A neck support that supports the user's neck from below when the user is lying on his or her back, and a shoulder support that extends to the left and right of the neck support and supports the left and right shoulder peripherals from below are both tipped in the vertical direction. A multi-layer structure having a urethane layer and high-resilience urethane layers disposed above and below the chip urethane layer may be employed.

With this configuration, the neck support portion that supports the user's neck from below when the user is lying on his or her back, and the shoulder support portions that are connected to the left and right sides of the neck support portion and support the left and right shoulder peripheral portions from below, The chip urethane layer with a multi-layer structure can suppress so-called sagging (deterioration of resilience after elastic deformation) due to the user's weight, and the high resilience urethane is placed on the upper and lower sides of the chip urethane layer. The layer makes it possible to obtain moderate elasticity.

In this bedding,
The end portion of the shoulder relief recess on the side of the neck support portion may be configured to have a curved shape that protrudes toward the neck support portion in a plan view.

With this configuration, it becomes easier to put the shoulders into the shoulder relief recesses when the user rolls over or lies down, and when the user lies on his or her back, the user's neck is easily supported from below by the neck support.

(a) and (b) are diagrams showing a usage example of the same embodiment, and (c) is an operation explanatory diagram. It is a figure which shows other embodiment, (a) is a top view, (b) is a front view. (a) and (b) are diagrams showing a usage example of still another embodiment.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of bedding according to the present invention will be described with reference to the drawings. In each figure, the same reference numerals are given to the same or corresponding parts.

As shown in FIG. 1, the bedding 10 of this embodiment includes:
A bedding having a recess into which the user's shoulders fit when the user (not shown) is lying down,
A neck support portion 11 is provided to support the user's neck from below when the user is lying on his or her back. Shoulder relief recesses 12 (L, R )have. A reference numeral 13 denotes a headrest that can support the user's head from below.

Since the bedding 10 has the above structure, the following effects are obtained.

When the user sleeps on the bedding 10, the user can sleep on his/her back with his/her neck resting on the neck support part 11.例文帳に追加Then, since the neck support part 11 supports the neck of the user from below, the neck is not burdened.

Also, when turning over or lying down, the user can turn over or lie down by inserting the shoulder into the shoulder relief recess 12 (L or R) on the left or right side of the neck support 11 . As a result, the pressure on the shoulders when turning over or lying down can be reduced. Especially effective for athletes.

As described above, according to the bedding 10, it is possible to reduce the pressure on the shoulders when turning over or lying down, and prevent a large burden on the neck when lying on one's back.

A neck support portion 11 that supports the user's neck from below when the user is lying on his or her back, and shoulder support portions 16 (L, R) that are connected to the left and right sides of the neck support portion 11 and support the left and right shoulder peripheral portions from below. , Both have a multi-layer structure including a chip urethane layer 10c and high-resilience urethane layers 10u disposed above and below the chip urethane layer 10c in the vertical direction (see FIG. 1C). ).

With this structure, the neck support portion 11 supports the user's neck from below when the user is lying on his or her back, and the shoulder support portions 16 are connected to the left and right sides of the neck support portion 11 and support the left and right shoulder peripheral portions from below. , the chip urethane layer 10c having a multi-layer structure can suppress so-called sagging (decrease in resilience after elastic deformation) due to the weight of the user, and is arranged on the upper and lower sides of the chip urethane layer 10c. Appropriate elasticity can be obtained by the high resilience urethane layer 10u.

For example, in the case of the above-mentioned patent document 1, unlike the bedding 10 of the present embodiment, in addition to not having a neck support, each part of the mattress is made of a material such as hard urethane having the same hardness ( 1) (paragraph 0010 of the same document).
For this reason, there is a problem that so-called "sagging" due to the user's weight is likely to occur in the parts on which the user's weight is applied, particularly in the parts supporting the left and right shoulders from below.

On the other hand, according to the bedding 10 of this embodiment, the neck support part 11 that supports the user's neck from below when the user is lying on his/her back and has the above-described configuration, allows the user to In addition, the high-rebound urethane layers 10u disposed on the upper and lower sides of the chip urethane layer 10c can provide appropriate elasticity.

An end portion 12c of the shoulder relief recessed portion 12 (L, R) on the side of the neck support portion 11 has a curved shape in which the side of the neck support portion 11 is convex in a plan view.

With this configuration, it becomes easier to put the shoulders into the shoulder relief recesses 12 (L, R) when turning over or lying down, and when lying on one's back, the user's neck can be well supported from below by the neck support part 11.例文帳に追加This is because the front and rear portions 11c of the neck support portion 11 are curved and wide.

The bedding 10 of this embodiment can be made of high-resilience urethane as a whole.
By incorporating the chip urethane layer (chip urethane block) 10c into the neck support portion 11 and the shoulder support portion 16, the above-described multi-layer structure is formed.

High-resilience urethane is a well-known material that is also called high-elasticity urethane. Due to its high elasticity, it is a material that has the property of rebounding and pushing back the body when weight or body pressure is applied.

Chip urethane is a well-known material made by pulverizing sponge offcuts, blending them with adhesive, putting them into a mold, and pressing them with steam. It is a material that has

The size and shape of the bedding 10 can be appropriately set.
The one shown in FIG. 1 is of a mattress type, and has, for example, a length L1 of about 1960 mm, a left and right width W1 of about 1000 mm, and a thickness T1 of about 120 mm.
The minimum width W3 of the neck support portion 11 is about 180 mm, and the length L3 of the headrest portion 13 is about 300 mm. The length L2 of the shoulder relief recess 12 is about 180 mm, and the depth T2 is about 90 mm.

For example, the chip urethane layer 10c has a width W2=W1=about 1000 mm, a length L4=about 380 mm, and a thickness T3=about 70 mm.
The thickness T4 of the high-resilience urethane layer 10u on the upper side of the chip urethane layer 10c is about 20 mm, and the thickness T5 of the high-resilience urethane layer 10u on the lower side is about 30 mm.

The bedding 10 of this embodiment is configured so as to be splittable via a joint portion 14 at approximately half positions in the longitudinal direction.

With this configuration, the bedding 10 can be easily transported by dividing it in the longitudinal direction.

An appropriate structure can be adopted for the structure of the joint portion 14. For example, in addition to the intermittent joint shown in FIG. 1, a dovetail structure as shown in FIG. 3 can be used.
With the joint structure of FIG. 1 or 3, the pressure from above can be well received without deviating in the longitudinal direction.

The bedding 10 of this embodiment can be used by placing a pillow according to the user's preference on the headrest portion 13 .

FIG. 2 shows a pillow proposed by the inventor of the present invention.
The pillow 20 can be made of an appropriate material, such as low-resilience urethane.
Low-resilience urethane, also known as low-resilience elastic urethane, is a material that has been processed to have low elasticity and high viscosity. have.

A feature of this pillow 20 is that, as shown in FIGS. , projecting above the shoulder relief recess 12 .

With this configuration, the user's neck can be well supported while the user's shoulders can be well accommodated in the shoulder relief recesses 12 when the user is lying down.

The pillow 20 and the headrest portion 13 can be joined by a known appropriate structure, for example, joining by hook-and-loop tape, sewing, adhesion, or the like.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and can be appropriately modified within the scope of the gist of the present invention.
for example,

As shown in FIG. 4, the bottom surface 12b of the shoulder relief recess 12 may be provided with a plate-like body 15 made of low-resilience urethane and having the same shape as the shoulder relief recess 12 in plan view. With this configuration, it is possible to reduce the load acting on the shoulders when lying down. The thickness of the plate-like body 15 can be appropriately set, and is, for example, about 30 mm. This structure is different from the above-mentioned Patent Document 4 in that the plate-like body 15 is provided only on the bottom surface 12b of the shoulder relief recess 12, and the recess is secured above it, so that it acts on the shoulder when lying down. load can be reduced.

As shown in FIG. 4, the thickness of the bedding 10 can be made thinner toward the toe direction.

As shown in FIG. 3, the chip urethane layer 10c may not necessarily be provided.
