Description

TECHNICAL FIELD The present invention relates to bedding, and in particular, a sheet-like bedding for a sleeping person to lie on, a top bedding that covers the sleeping person lying on the bedding, and a bedding provided between the top bedding and the bedding. and a covering sheet member.

BACKGROUND ART In daily life, a sleeper lays down on a bedding such as a futon or a mattress of a bed, and sleeps while covering the bedding such as a quilt, a blanket, or a towel blanket. A sleeper selects and uses an appropriate thickness, size, weight, and material of throw-up bedding according to the season, the temperature and humidity of the bedroom, or the amount of clothes worn by the sleeper.

BACKGROUND OF THE INVENTION A sleeper unconsciously rolls over several times during sleep, and when the sleeper rolls over, the top bedding worn by the sleeper may slip off from its fixed position. This slippage of the top bedding is a problem that occurs regardless of the type of bedding, and is particularly frequent when light and thin bedding (eg, blankets, towel blankets, etc.) is used. When the top bedding slides down, a part of the body is exposed, so the body comes into contact with cold air in a season such as winter when the room temperature is low. As a result, the sleeping person's body temperature drops and wakes up, disturbing comfortable sleep.

On the other hand, using heavy and thick bedding (e.g., comforter) as an overlay can reduce the occurrence of slipping compared to lighter bedding, but still slips due to the sleeper turning over or kicking. Occur. In addition, since thick bedding is thick, it is difficult to bend along the body line of the sleeper. As a result, a gap is generated between the top bedding and the sleeper, allowing cold air to enter. When the body comes into contact with cold air, the sleeper's body temperature drops and wakes up, disturbing comfortable sleep.

Conventionally, there has been known a configuration in which an overhanging bedding is fixed to a bedding in order to prevent the overhanging bedding from slipping down and the occurrence of gaps (see, for example, Patent Document 1). Specifically, in this bedding, a plurality of stretchable elastic cords are used to fix the periphery of the top bedding to the periphery of the bedding. This prevents the top bedding from moving from its fixed position even when the sleeping person turns over. In addition, since the top bedding is brought into close contact with the sleeper by the restoring force of the plurality of elastic cords, no gap is formed between the top bedding and the sleeper.

JP 2016-129552 A

However, in the bedding of Patent Document 1, a plurality of rubber cords having a relatively strong restoring force are used in order to bring the entire flat surface of the top bedding into close contact with the body of the sleeper. The comforter and the mattress are pulled together with a relatively strong force. For this reason, there is a problem that a strong force locally acts on a part of the sleeping person's body, and the sleeping person wakes up feeling pressure on the part of the body.
In addition, since the rubber cord exerts a local strong tensile force on the attachment portion (root) of the rubber cord of the top bedding and the bedding, there is a risk of tearing or deterioration.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the conventional bedding, and aims to provide a bedding that can provide a comfortable sleep to the sleeper and improve the durability of the bedding. purpose.

First, the bedding of one embodiment of the present invention will be described with reference to FIGS. 1 and 2. FIG.
The bedding 1 of this embodiment is a futon set for a sleeping person to lie down and sleep. The bedding 1 of this embodiment consists of a bedding 10 that is placed directly on the floor or tatami mat in a bedroom, a top bedding 20 that covers the sleeping person from above, and the bedding 10 and the top bedding 20. and a covering sheet member 30 disposed therebetween. The bedding 1 of the present embodiment is of a single size (for one person), but is not limited to this, and may be of double size (for two people) or triple size (for three people).

The bedding 10 is, for example, a commercially available sheet-like bedding, and is a part on which a sleeper lays down along the longitudinal direction. The bedding 10 has, for example, a rectangular shape (rectangular parallelepiped shape), the length in the longitudinal direction (longitudinal direction) is about 200 cm, the length in the width direction (horizontal direction) is about 100 cm, and the thickness (the length in the height direction is about 100 cm). height) is about 7 cm. The mattress 10 is, for example, a lightweight mattress with a total weight of about 5.5 kg so that it can be easily carried when not in use. The bedding 10 can suppress the reaction force from the floor from being directly transmitted to the sleeping person by the elasticity of the bedding, and can maintain the natural shape of the spine and sleep in an ideal sleeping posture. ing. The bedding 10 preferably has a thickness of about 5 cm or more in order to maintain an ideal sleeping posture. Further, when a bed mattress is used as the bedding 10, the thickness from the lower surface of the bedding 10 to the upper surface of the cover bedding 20 is about 70 cm or more.

In addition, the material used for the bedding 10 is preferably made of cotton, which absorbs sweat easily and is comfortable to the touch. may be used. Furthermore, in addition to natural fibers suitable for heat retention, fabrics of synthetic fibers and chemical fibers, such as urethane, tetron, polyester, and nylon fabrics, can be employed as materials that are pleasant to the touch and excellent in heat retention.

The bedding 10 is adapted to suit the sleeper's taste by selecting an appropriate size, thickness, hardness, material, etc. according to the season, room temperature, humidity, age or sex of the sleeper, etc. bedding is used. The bedding 10 is not limited to a futon, and instead of a futon, a bed mattress, a thin futon, a blanket, or the like can be used. The bedding of this embodiment is used without being covered with a sheet, but the surface of the bedding may be covered with a sheet to prevent staining of the bedding.

The top bedding 20 is a variety of comforters such as commercially available products and handmade products such as hand-knitted fabrics. It is the part that covers from above. The top bedding 20 is, for example, formed in a rectangular shape larger than the outline of the bedding 10, and has a length of about 250 cm in the longitudinal direction and a length of about 180 to 200 cm in the width direction. The top bedding 20 is, for example, a lightweight comforter with a total weight of about 1.8 kg so that it can be easily carried when not in use. The top bedding 20 is made of a material and thickness that does not allow cold air to pass through, and is made of a weight that does not make the sleeper feel oppressive.

The top bedding 20 is a bedding on the market. Two pieces of bedding having a length of about 75 cm in the width direction are prepared, and the two pieces of top bedding are arranged in the width direction and sewn together to obtain a width of the top bedding. It may be configured such that the length in the direction is approximately 150 cm. This reduces the material cost of the coverlet and also allows the seams to be used as markers when aligning the covercover with respect to the mattress.

Also, the material used for the top bedding 20 may be knitted yarn, woolen woolen fabric, silk fabric, or cotton fabric. Furthermore, in addition to natural fibers and lyocell, synthetic fibers, chemical fiber fabrics, feathers, and the like may be used. The top bedding 20 is suitable for the sleeper by appropriately selecting the appropriate size, thickness, hardness, material, etc. according to the season, room temperature, humidity, age or sex of the sleeper, etc. Fitted bedding is used. As the top bedding 20, a lightweight item such as a blanket or a towel blanket may be used.

In addition, the top bedding 20 is woven thicker than the other regions in the longitudinal direction up to about 10 cm from the edge on the head side or the toe side in a plan view. Similarly, the top bedding 20 is woven thicker than the other regions at the ends up to about 10 cm from the left and right edges in the width direction. As a result, the ends of the top bedding 20 hang down vertically due to their own weight and come into contact with the floor surface (see FIG. 6). Frictional resistance is generated on the contact surface by the contact between the end portion of the top bedding 20 and the floor surface, so that the top bedding 20 can be prevented from slipping down. In addition, since the frictional resistance increases as the thickness of the top bedding 20 increases, it is possible to prevent the top bedding 20 from slipping down. Since the ends of the top bedding 20 come into contact with the floor surface, they are preferably made of inexpensive materials. It should be noted that the larger the surface area of the top bedding 20, the more it is possible to suppress slipping down.

The top bedding 20 is woven partially thicker to meet the needs of the sleeper, partially to increase heat retention. For example, if the sleeper is sensitive to cold, the top bedding 20 is thickly woven from a position of 30 cm to a position of 50 cm in the longitudinal direction with reference to the edge on the toe side in plan view. You can intensively heat your toes.

In plan view, the top bedding 20 has ends up to about 10 cm in the longitudinal direction from the edges on the head and toe sides and ends up to about 10 cm in the width direction from the left and right edges. It is knitted by a knitting method different from that of the region. Specifically, the direction of stitches differs by approximately 90 degrees between each end portion and the portion of the other region. As a result, it is possible to prevent the ends of the top covering bedding 20 from curling up.

The covering sheet member 30 is a portion that surrounds the entire widthwise circumference of the bedding 10 and the sleeper. The covering sheet member 30 is made of a stretchable material so that the sleeping person can move freely within the covering sheet member 30 .

2 and 3, the covering sheet member 30 includes a first covering sheet member 32, a second covering sheet member 34 covering the outer circumference of the first covering sheet member 32, and a second covering sheet. It is provided with a third covering sheet member 36 that covers the outer periphery of the member 34, and has a three-layer multi-layered structure. The first covering sheet member 32, the second covering sheet member 34, and the third covering sheet member 36 are formed in the shape of bags of the same shape and size, and have a length of about 250 cm in the longitudinal direction and a length of about 250 cm in the width direction. It is formed in a rectangular shape with a length of about 160 to 200 cm. The cover sheet member 30 comprises a first cover sheet member 32 inserted into a second cover sheet member 34 and a first cover sheet member 32 and a second cover sheet member 34 inserted into a third cover sheet member 36 . It is configured by being inserted into That is, this multi-layered structure is constructed by sequentially inserting the covering sheet members of other bags inside the covering sheet member of the bag.

Each of the covering sheet members 32, 34, 36 includes upper sheet members 32a, 34a, 36a, which are rectangular cloths, and lower sheet members 32b, 34b, which are cloths of the same shape and size as the upper sheet members. , 36b. Each covering sheet member is formed by stitching the upper sheet members 32a, 34a, 36a and the lower sheet members 32b, 34b, 36b together with a thread 37 in a state in which the upper sheet members 32a, 34a, 36a are overlapped. Note that each covering sheet member may be constructed by joining a plurality of small rectangular sheets together. In this case, material costs can be reduced by stitching together mass-produced, relatively inexpensive commercially available cloths. In addition, the thread seams can be used as marks when aligning the covering sheet member 30 and the bedding 10 .

Each of the covering sheet members 32, 34, 36 is configured such that the upper sheet members 32a, 34a, 36a and the lower sheet members 32b, 34b, 36b overlap each other in a plan view, and the peripheral edges of the upper sheet member and the lower sheet member overlap each other. Among the parts, left edge portions 32c, 34c, 36c, right edge portions 32d, 34d, 36d, and toe side (bottom side) edge portions 32e, 34e, 36e are sewn together with thread 37. (See Figure 3). That is, each of the covering sheet members 32, 34, 36 is sewn with thread 37 in a U-shape in plan view, except for the edge portion on the head side of the sleeper. Openings 32f, 34f, and 36f are formed in each of the covering sheet members 32, 34, and 36 by opening the edges on the head side of the sleeping person (see FIG. 2).

The openings 32f, 34f, 36f of the covering sheet members 32, 34, 36 have opening areas large enough for the bedding 10 and the sleeping person to pass through. Thus, the bedding 10 is inserted through the opening 32f of the first covering sheet member 32, and the bedding 10 is accommodated inside the first covering sheet member 32. As shown in FIG. In addition, the first covering sheet member 32 allows the sleeping person to enter through the opening 32f while the bedding 10 is stored in the first covering sheet member 32.例文帳に追加In hot summer months, a highly absorbent sheet such as a towel blanket may be laid on the lower sheet member 32b of the covering sheet member 32. FIG.

Each of the covering sheet members 32, 34, 36 is made of cloth knitted by knitting and is formed to be stretchable. Each of the covering sheet members 32, 34, 36 is formed by, for example, knitting or woven sheet-like fabric made by knitting elastic linear material, or by knitting elastic linear material or non-elastic linear material with rubber knitting. It may be formed of a sheet-like knitted fabric or woven fabric imparted with stretchability.

In the first covering sheet member 32, a portion of a predetermined length in the longitudinal direction from the edge of the head side, which contacts the neck of the sleeper, is provided with a detachable cover so that it can be replaced when soiled. A flexible cover may be used. This cover is detachably attached to the first covering sheet member 32 by a zipper or the like. This cover has the same length in the width direction as the first covering sheet member 32, and is about 160 to 200 cm. The longitudinal length of the cover is half the length of the first covering sheet member 32, which is approximately 160 to 200 cm. It should be noted that the cover may be configured to have a longer length in the longitudinal direction and be folded back on the head side to cover the top bedding 20 . As a result, it is possible to suppress and stabilize the entire bedding from slipping.

The upper sheet member 32a of the first covering sheet member 32 has a longitudinal length longer than that of the second covering sheet member 34 and the third covering sheet member 36, and is folded back at the head side to form the upper bedding 20. It may be configured to cover the top. In this case, the upper sheet member 32a of the first covering sheet member 32 is formed so that the longitudinal length of the folded portion is approximately 125 cm or more. As a result, the folded portion of the upper sheet member 32a of the first covering sheet member 32 covers the second covering sheet member 34, the third covering sheet member 36, and the head-side end of the top bedding 20, It is possible to prevent the second covering sheet member 34, the third covering sheet member 36 and the ends of the top covering 20 from being soiled.

Since each covering sheet member 32, 34, 36 is made of an elastic material, the material itself or the method of weaving generates a restoring force to restore the original shape. The openings 32f, 34f, and 36f of the respective covering sheet members extend to such a size that a sleeping person can pass through them while the bedding 10 is accommodated in the first covering sheet member 32.例文帳に追加Further, each of the covering sheet members 32, 34, 36 shrinks toward the bedding 10 and the sleeper in a state where the sleeper is lying on the bedding 10 and is brought into close contact with the body of the sleeper. Therefore, even if the sleeping person rolls over while sleeping, the covering sheet members 32, 34 and 36 are adapted to closely adhere to the body of the sleeping person following the change in posture of the sleeping person.

Referring to FIG. 4, the first covering sheet member 32 is formed by bonbon weaving. A plurality of bonbons 39, which are small spheres, are sewn on the lining of the upper sheet member 32a of the first covering sheet member 32. As shown in FIG. The bonbon 39 is provided on the entire surface of the lining of the upper sheet member 32a. A plurality of small spaces are formed between the bonbons 39 by the plurality of bonbons 39 to obtain a heat insulating effect. This allows the sleeper to sleep warmly.

Each of the covering sheet members 32, 34, 36 may be formed by knitting, rubber knitting, loop knitting, chain knitting, etc., instead of bonbon knitting, as long as they are stretchable. In addition, when each of the covering sheet members 32, 34, 36 is made of yarn, the thicker the yarn, the better the adhesion to the sleeping person and the heavier the sleeping person. become. However, the thinner the yarn, the lighter the weight, so it is possible to prevent the sleeping person from feeling oppressive. It is most preferable that each covering sheet member is made of cashmere material because it is comfortable to sleep on.

In addition, since the first covering sheet member 32 comes into direct contact with the sleeper, it is preferable to use materials that are gentle on the skin, such as natural fibers such as cotton and hemp, Tencel (registered trademark), and lyocell. Natural fibers such as cotton and hemp are more absorbent than other materials and can improve the comfort of sleep. In addition, when a sheet having a structure in which floss and a degreasing surface are laminated is used, heat retention and water absorbency can be improved.

Each of the covering sheet members 32, 34, 36 can be composed of a bandage-like sheet for medical use. In this case, the first covering sheet member 32 is formed to have a larger surface area than the second covering sheet member 34 and the third covering sheet member 36 in plan view. This makes it easier for the sleeper to enter the covering sheet member, and prevents the covering sheet member from shifting with respect to the bedding.

Also, each of the covering sheet members 32, 34, 36 can be made of an aluminum-like adhesive sheet or an aluminum fabric. Thereby, the durability of the covering sheet member can be improved. Since aluminum-like adhesive sheets and aluminum fabrics are thin and easily displaced, they may be configured so that they can be fixed to other members by attaching a cloth tape with a small width (for example, about 2 cm) to the edges. . Each of the covering sheet members 32, 34, 36 may be formed of a heat-accumulating aluminum-like sheet, with the inner side being gold and the outer side being silver.

The first cover sheet member 32 may be configured by sandwiching a sheet made of floss or absorbent cotton between cloth sheets from above and below. As a result, it is possible to improve the heat retaining property and the wicking and absorbing properties of moisture. In addition, a double structure may be formed by superimposing floss and absorbent cotton sandwiched between cloth sheets.

In the present embodiment, the upper sheet members 32a, 34a, 36a and the lower sheet members 32b, 34b, 36b are joined with threads, but instead of these threads, the threads are joined by detachable means such as zippers, buttons, strings, and hook-and-loop fasteners. You may As a result, it is possible to improve the convenience of putting in and out heat insulating sheets 40 and 42, which will be described later. In the present embodiment, the covering sheet member 30 is fully opened on the sleeping person's head side, but instead of this, only a part thereof may be opened. You may enable it to adjust the opening area of .

In each of the covering sheet members 32, 34, 36, both the upper sheet members 32a, 34a, 36a and the lower sheet members 32b, 34b, 36b are made of stretchable material. , 36a may be made of a stretchable material, and the lower sheet members 32b, 34b, 36b may be made non-stretchable. Although the covering sheet member 30 is composed of three layers of the first covering sheet member 32, the second covering sheet member 34 and the third covering sheet member 36, it is composed of only one layer of the first covering sheet member 32. Alternatively, fourth and fifth covering sheet members may be added to form four or five layers.

Referring to FIG. 3, on the upper side of the first covering sheet member 32 and the second covering sheet member 34, a first heat insulating sheet 40 and a second heat insulating sheet for keeping the body temperature of the sleeping person during sleep are provided. 42 are placed respectively. Specifically, the first heat insulating sheet 40 is arranged between the upper sheet member 32 a of the first covering sheet member 32 and the upper sheet member 34 a of the second covering sheet member 34 . A second heat insulating sheet 42 is arranged between the upper sheet member 34 a of the second covering sheet member 34 and the upper sheet member 36 a of the third covering sheet member 36 . Each heat insulating sheet is appropriately selected and used according to the season, room temperature, and humidity. In this embodiment, each heat insulating sheet has the same shape and size as the covering sheet members 32, 34, and 36 in plan view, and has, for example, a length of about 250 cm in the longitudinal direction and a length of about 160 cm in the width direction. Formed at ~200 cm.

The first heat insulating sheet 40 is inserted into the second covering sheet member 34, and the inner four corners of the second covering sheet member 34, the central portion in the longitudinal direction, and the central portion in the width direction to prevent deviation. Part is secured with a string. In addition, the second heat insulating sheet 42 is inserted into the third covering sheet member 36, and in order to prevent deviation, the inner four corners of the third covering sheet member 36, the central portion in the longitudinal direction, and the width direction. In the central part of the, it is fixed by a string.

Each heat insulating sheet is made of cloth knitted by knitting so as to be stretchable. Also, each heat insulating sheet may be made of a material having excellent heat insulating properties, such as a knitted natural fiber such as cashmere, angora, yak, camel, or wool. In particular, when cashmere is used for each heat insulating sheet, the material is light and comfortable to sleep on. In addition, chemical fibers such as acrylic, nylon, and polyurethane may be used for each heat insulating sheet, and these materials may be blended with natural fibers to enhance heat retention. Further, each heat insulating sheet may be constructed by bonbon knitting similarly to the covering sheet member, and the lining of the heat insulating sheet may be provided with a bonbon.

Referring to FIG. 2, a friction force reducing member 50 is placed on the upper surface of the upper sheet member 36a of the third covering sheet member 36. As shown in FIG. Specifically, the friction force reducing member 50 is positioned between the top bedding 20 and the third covering sheet member 36 . The frictional force reducing member 50 has the same shape and size as the covering sheet members 32, 34, 36 and the heat insulating sheets in plan view, and has a length of about 250 cm in the longitudinal direction and a length of about 250 cm in the width direction. Formed at about 160-200 cm. The frictional force reducing member 50 is arranged so as to be centered on each of the covering sheet members 32, 34, 36 and each heat insulating sheet in plan view.

The frictional force reducing member 50 is made of a material having relatively low frictional resistance so as to suppress the generation of frictional force on the contact surface between the top bedding 20 and the third covering sheet member 36 . For example, the frictional force reducing member 50 is made of a material with a small coefficient of friction, such as nylon, fluororesin, silk, or Tencel (registered trademark). In this embodiment, an example of using a rectangular sheet as the frictional force reducing member is shown, but instead of the rectangular sheet, a mesh sheet may be used, or a plurality of sheets may be used. may be separated and attached to the surface of the third covering sheet member 36 .

Next, with reference to FIGS. 5 and 6, the mode of use of the bedding according to one embodiment of the present invention will be described. With the bedding 10 inserted into the first covering sheet member 32, the sleeper enters the covering sheet member 30 through the opening 32f of the first covering sheet member 32 and extends in the longitudinal direction of the bedding 10. lie along. Since each of the covering sheet members 32, 34, 36 is made of a stretchable material and is formed so as to shrink toward the sleeping person, each of the covering sheet members 32, 34, 36 can be adjusted to the sleeping person's body while the sleeping person is lying down. (see FIG. 5). As a result, there is almost no gap between the sleeping person and the first covering sheet member 32 .

When the sleeper rolls over from the state of lying on his/her back (FIG. 6(a)) to the state of lying on his/her side (FIG. 6(b)), the covering sheet member 30 is adapted to the change in posture of the sleeping person. It follows and adheres to the sleeping person's body. When the sleeper rolls over, a large gap S1 is normally generated between the top bedding 20 and the sleeper, but since the covering sheet member adheres to and follows the sleeper's body, the sleeper and the first covering sheet do not. Only a slight gap S2 is generated between the member 32 and the member 32. As shown in FIG. As a result, no matter what posture the sleeping person takes, there is only a slight gap, so it is possible to suppress direct contact with the body of the cold air when the sleeping person rolls over.

Also, when the sleeper rolls over from the back to the side, since the frictional force reducing member 50 is made of a material having a relatively small frictional resistance, the frictional force reducing member 50 does not adhere to the third covering sheet member 36. It is possible to prevent the top bedding 20 from being dragged and slipped down, and it is also possible to prevent the top bedding 20 from being dragged by the frictional force reducing member 50 and slipping down. When the third covering sheet member 36 is made of a material that easily wrinkles on the surface, the plurality of wrinkles can reduce the contact area between the third covering sheet member 36 and the frictional force reducing member 50, thereby reducing the frictional force. It is possible to further suppress the reduction member 50 from being dragged by the third covering sheet member 36 and slipping down.

As shown in FIG. 6, the left and right edges of the top bedding 20 in the width direction are in contact with the floor surface, and even when the sleeper rolls over from the back to the side, the edges of the top bedding 20 are in contact with each other. edge is in contact with the floor. Therefore, cold air can be prevented from entering the top bedding 20, and the sleeper can sleep in a warm state.

Another embodiment of the present invention will now be described with reference to FIG.
In FIG. 7, standing walls 60 are provided along the outline of the bedding 1 so as to surround the entire perimeter of the bedding 1 in plan view. The standing wall 60 is composed of a left standing wall 60a, a right standing wall 60b arranged in the longitudinal direction, a toe side standing wall 60c and a head side standing wall 60d arranged in the width direction. The left standing wall 60a and the right standing wall 60b are formed, for example, with a length of 200 to 260 cm in the longitudinal direction, and the toe side standing wall 60c and the head side standing wall 60d are formed with a length of, for example, 150 to 210 cm in the width direction. . The height of each vertical wall is, for example, 40 to 70 cm, and is set equal to or higher than the body height of the sleeper lying on the bedding 1 . As a result, even if the sleeper rolls over, the movement of the top bedding 20 is restricted by the vertical wall 60 so that it does not fall off the upper surface of the sleeper.

The vertical wall 60 includes, for example, an L-shaped plate frame arranged along the bedding 10, supports arranged at least at the four corners of the bedding 1, and belt-like cloth or net stretched between the supports. It is formed of a cloth frame or mesh frame, a rectangular box-shaped wooden frame arranged so as to surround the bedding 1, a tube frame, a sponge frame, a styrene foam block, and the like. Also, if a beautiful fabric, a panel with a mural painting, or the like is used as the standing wall 60, the sleeping person can sleep more comfortably.

The L-shaped plate frame is composed of a vertical plate extending vertically and a horizontal plate extending horizontally from the lower end of the vertical plate. The L-shaped plate frame is fixed by the dead weight of the bedding 1 by placing the horizontal plate under the bedding 10 . The L-shaped plate frame is such that the vertical plate of the bedding 1 stands upright in the fixed state. Two L-shaped plate frames are provided on each of the left side and the right side adjacent to at least the left and right edges of the bedding 10 in a plan view. The L-shaped plate frame is made of iron plate, pipe, lumber, log, or the like. In addition, it is preferable to cover the L-shaped plate frame with a cushioning material such as rubber in consideration of safety. Furthermore, when cloth is stretched between a plurality of L-shaped board frames, it is possible to reliably prevent the top bedding 20 from falling from the upper surface of the sleeper.

The strip-shaped cloth frame is configured by stretching cloth between a plurality of posts erected around the bedding 1 in a plan view. For example, in a plan view, two pillars are installed in the longitudinal direction on the left or right side of the bedding 1, and two pillars are installed in the width direction on the head side and the toe side at equal intervals. The belt-shaped cloth frame is fixed to the support by means of rubber, string, or the like. A strip-shaped cloth frame is more economical than an L-shaped plate frame, and can reduce material costs. In addition, it is preferable to cover the support with a shock absorbing material such as rubber or cloth in consideration of safety.

The mesh frame is constructed by stretching a mesh between a plurality of posts erected around the bedding 1 in plan view. For example, four supports are installed at the four corners of the bedding 1 in plan view. Hooks are attached to the pillars, and a net frame is stretched by hooking the net on the hooks of each pillar. Compared to an L-shaped plate frame or a band-shaped cloth frame, the material cost can be reduced, and the sleeper does not feel oppressive and does not disturb waking up. Both ends of the rope frame are pulled by a rubber cord or the like in order to prevent the rope from sagging.

Instead of fixing the net to the pillar, the rope frame uses a rectangular net that surrounds the bedding 1 in plan view, and pulls the four corners of this net with four ropes fixed to the ceiling. , you may set up vertically like a hammock. The rope frame is formed with a length of 220 cm in the longitudinal direction, a length of 150 cm in the width direction, and a height of 40 cm in a plan view, for example. The net is made of materials such as natural fibers and chemical fibers. If a rubber cord is attached to the tip of the rope, the rope will not slack at all times.

A rectangular box-shaped wooden frame is provided with two plates on the right side and the left side and two plates on the head side and the toe side so as to surround the bedding 1 in plan view, and includes nails and bolts. Alternatively, they are connected by nuts or the like. Since the box-shaped wooden frame is stronger and more durable than the L-shaped board frame, it is possible to prevent the thick and heavy bedding from slipping off the upper surface of the sleeper. The box-shaped wooden frame is, for example, 220 cm long, 150 cm wide, and 40 cm high. The box-shaped wooden frame is not limited to a rectangular shape, and may be formed in a polygonal or circular shape.

The tube frame is configured by a vinyl or rubber tube so as to surround the bedding 1 in plan view. The tube is constructed by stacking a plurality of air layers, which are small closed spaces, in the vertical direction. Since the tube is inflated with air, the sleeping person can sleep warmly due to the heat insulating effect of the air layer. The tube frame is, for example, 260 cm long, 170 cm wide (300 cm for double size), and 45 cm high. The width of the tube frame is set to 50 cm or less so that the sleeping person can easily step over it.

A frame made of sponge and a block made of polystyrene foam are erected so as to surround the bedding 1 in plan view. Commercially available blocks made of sponge or polystyrene foam can be used. A frame made of sponge and a block made of expanded polystyrene are lightweight and can improve workability. In addition, since sponge and polystyrene foam have high heat insulating performance, the sleeping person can sleep in a warmer state. The frame made of sponge and the block made of Styrofoam are formed, for example, with a length of 250 cm in the longitudinal direction, a length of 150 cm in the width direction, and a height of 50 cm. The width of the frame made of sponge and the block made of Styrofoam is set to 10 cm to 50 cm so that the sleeping person can easily step over it.

The upper side of the standing wall 60 is covered with a rectangular top sheet 70 that is larger than the outline of the standing wall 60 in plan view (see FIG. 7). The upper sheet 70 is made of wool fabric, plain weave fabric, heat insulating sheet, vinyl base sheet, or the like. The upper surface sheet 70 is placed on the upper end of the vertical wall 60 and is configured to cover the upper opening surrounded by the vertical wall 60 and the wall surface of the vertical wall 60 . As a result, the upper opening can be made smaller, so that the sleeping person can sleep in a warmer state. The material of the upper sheet 70 is selected according to the season, and when wool is used in the cold season, the appearance can give a warm impression. In addition, if a heavy material is used for the top sheet 70, the top sheet 70 is pulled downward by its own weight, and wrinkles can be suppressed.

Another embodiment of the present invention will now be described with reference to FIG.
As described above, the top bedding 20 is, for example, formed in a rectangular shape larger than the outer shell of the bedding 10, and has a longitudinal length of approximately 250 cm and a widthwise length of approximately 180 to 200 cm. However, when used by a large person, a tall person, or a person who sleeps badly, a part of the body may be exposed. On the other hand, if it is designed in a large size so as not to expose the top bedding, the size is more than necessary for a small person or a person who sleeps well, which is economically unfavorable. In this embodiment, the top bedding 20 is composed of a main sheet 20a and an additional sheet 20b, and the additional sheet 20b is detachably connected to the main sheet 20a.

The additional sheet 20b is detachably connected to the left edge of the main sheet 20a of the upper bedding by a fastener 22 (connecting means). has a length of about 250 cm in the longitudinal direction and a length in the width direction of 200 cm to 240 cm. This allows additional sheets to be expanded to meet the sleeper's needs without the need to purchase new oversize bedding.

In this embodiment, the fastener 22 is used as the connecting means, but instead of the fastener 22, it may be sewn with thread, or the top bedding 20 and the additional sheet 20b may be connected with a button or hook-and-loop fastener. good.

The bedding 1 of this embodiment can be used not only in winter but also in summer. The covering sheet member used in summer is joined in the longitudinal direction at the left and right edge portions of the upper and lower sheet members up to a position about 30 cm from the toe side edge, and from that position to the head side. Open to the edge. A connector such as a zipper, a string, or a button is used to join the upper and lower sheet members so that the lengths of the joined portion and the open portion can be changed. As a result, when it is hot in summer, the length of the open portion in the longitudinal direction can be lengthened by the connector, and when it is cool, the length of the joint portion in the longitudinal direction can be lengthened, so that a comfortable sleep can be provided. A towel blanket having high water absorption is inserted in the covering sheet member, and the towel blanket is fixed to the inside of the covering sheet member by strings or the like at both ends in the width direction and at the central portion. As a result, the towel blanket is not biased in the covering sheet member and does not separate from the sleeper's body.

Next, the effects of this embodiment will be described.
