DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sleeping rug which can be used for going to bed or the like, and more particularly to a sleeping rug which can be used as a simple bed or as a bed mattress.

[0002]

2. Description of the Related Art A typical example of a sleeping rug is a bed mattress.

[0003] Such a bed mattress is made of various materials, and usually incorporates spring means such as a coil spring. Recently, a bed mattress in which a bag is filled with water has also been proposed.

[0004] Other than the bed mattress, there are so-called goza, mats and the like which have been known for a long time as a sleeping rug, and a relatively thin synthetic resin sheet rug or an elastic synthetic resin material is now used. There are also formed elastic rugs and air-filled rugs used by filling the inside with air.

[0005] The former rug is used exclusively for beds,
Many are devised so that no local, intensive reaction force is applied to the human body sleeping on it.

The latter rugs include floors, building terraces, lawns,
Used on the beach, poolside, in the car, etc.

[0007]

However, a bed-only mattress is devised so that it is comfortable to sleep by preventing local and concentrated reaction forces from being applied to a human body sleeping thereon, but it is bulky. , Heavy, complicated in structure, often expensive, and expensive
Some are still not comfortable enough.

[0008] Further, since the bed mattress is bulky and heavy, it is not suitable for being used as a bed, such as sleeping on a floor, on a terrace of a building, on a lawn, in a car or the like.

On the other hand, goza, mats, synthetic resin sheet rugs, relatively thin elastic rugs, air-filled rugs and the like are relatively easy to transport and move, and are used for floors, terraces of buildings, lawns, ground, vehicles, and the like. Can be easily spread and used. If necessary, it can be easily used as a bed rug. However, even when used on the floor,
Even when used as a bed rug, concentrated reaction force is likely to be applied to each part of the human body that sleeps on it or a local part of the human body, making it extremely uncomfortable to sleep and comfortable. If used over the floor, floor rubbing is likely to occur.

Therefore, the present invention provides a floor (for example, a floor of a room where a sick person is nursing), a terrace of a building, which is smaller in bulk, lighter in weight, can be easily transported and moved as compared with a conventional bed rug. , Lawn, beach, poolside, campsite,
It can be used as a simple bed when laid in a car or the like, as a rug for meals, rest, etc.It can also be used as a rug for beds when laid on a bed, and it is localized and concentrated on the human body sleeping on it It is an object of the present invention to provide a sleeping rug that is suppressed in the application of an excessive reaction force, has good sleeping comfort, is simple in structure, and can be manufactured at low cost.

[0011]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention has a raised ridge portion having a mountain-shaped cross section which is raised in a cross-sectional shape and a thicker head in a cross-sectional shape, and a lower portion continuous therewith is a narrower saw than the head. A first member made of an elastic material, which is entirely flat, having a top portion in which mushroom-shaped raised ridge portions having a raised shape are alternately formed in parallel;
A concave ridge portion applied to the raised ridge portion of each cross-sectional mountain shape,
A convex ridge fitted between the heads of the adjacent mountain-shaped ridges and the mushroom-shaped ridge, and a concave ridge applied to the head of each mushroom-shaped ridge. A second member made of a resilient material having a corrugated top surface having a cross-section having the following shape. The present invention provides a sleeping rug that can be compressed and deformed independently of other mushroom-shaped raised ridges and mountain-shaped raised ridges by receiving a load.

In the sleeping rug according to the present invention, the first member is arranged below (or above), and the first member is arranged above (or below).
Disposing the second member and placing the second member on the second member (or the first member);
A human body is positioned and used (on a member). It should be noted that although there is a rug for sleeping and resting, it goes without saying that it can be used not only for sleeping but also for sleeping, etc., regardless of its name, and can be used instead of a cushion for sitting.

In the sleeping rug according to the present invention, when the rug is laid on a desired place and the human body lies on the rug, the weight of the human body is transmitted to the top of the first member. This transmission of the human body load is achieved by the fact that the concave ridges on the corrugated top surface of the second member are applied to the raised ridges having a mountain-shaped cross section and the mushroom-shaped raised ridges of the first member. , Are smoothly transmitted to the heads of the mountain-shaped ridges and the mushroom-shaped ridges.

At this time, an air gap is left beside the lower part continuous with the head of the mushroom-shaped raised ridge portion, that is, the convex ridge portion on the top surface of the corrugated cross-section of the second member has an adjacent cross-section. Only a gap is inserted between the heads of the mountain-shaped ridges and the mushroom-shaped ridges, leaving a gap behind the head, and a gap is left beside the lower part of the mushroom-shaped ridge. Therefore, the portion of the mushroom-shaped raised ridge to which the human body load is applied is easily deformed into this gap, and is more easily deformed than the raised ridge having a mountain-shaped cross section. It can be compressed and deformed independently of the ridges having a mountain-shaped cross section.

Thus, as a whole, the human body load is supported by the ridges having a mountain-shaped cross section and the mushroom-shaped ridges at the top of the first member, and the portions of the ridges to which the human body load is applied are deformed. And, at that time, the portion of the mushroom-shaped raised ridge portion to which the human body load is applied is easily and easily compressed and deformed independently. The top part of one member is smoothly recessed, and as a result, the reaction force applied to each part of the human body from the rug according to the present invention is made uniform for each part of the human body, so that the rug of the present invention is comfortable and comfortable to sleep on. Further, even when used by a sick person or the like for a long time, floor rubbing and the like hardly occur.

In the sleeping rug according to the present invention, the first member and the second member are formed of an elastic material. First
It can be absorbed by deformation of the lower surface of the member or the second member, and in this respect, it can be used comfortably.

The rug according to the present invention can be manufactured to be relatively thin, thus having a low bulk and a light weight, with the above-described structure for making the reaction force applied to each part of the human body from the rug uniform. It can be easily transported and moved to a desired location, for example, a floor (eg, a floor of a room where a sick person is nursing), a building terrace, a lawn, a ground (the ground such as a beach or a river), a poolside, a car. It can be used as a rug for cots, meals, rest, etc.
It can also be used as a bed rug (bed mattress) by laying on a bed. In addition, it can be used as a leisure rug by laying on a lawn, the ground (ground such as a beach or a river), a poolside, in a car, a boat, or the like.

The sleeping rug according to the present invention has a simple structure and can be manufactured at low cost.

The first member and the second member constituting the sleeping rug according to the present invention are each formed of an elastic material. As such an elastic material, foamed polyurethane, foamed polyethylene, foamed polypropylene, foamed polyvinyl chloride is used. And the like, various types of fibrous structures, and combinations thereof.

Regardless of which material is used, the first member is higher in resilience than the second member so that the reaction force applied to each part of the human body from the rug according to the present invention can be made more uniform in each part of the human body. It can be recommended to be formed of a material.

[0021] As the material of the first member, a relatively large repulsive elasticity, density 30kg / m ³ ~70kg / m ³ approximately, hardness 120N~270N about elastic foamed resin (typically high density foam polyurethane) And the material of the second member may have a low rebound resilience and a density of 40.
kg / m ³ ~70kg / m ³ approximately, hardness 10N~100
An elastic foamed resin of about N (typically, low-elasticity foamed polyurethane) can be exemplified. Preferably, those having a rebound resilience of less than 20% can be mentioned. Of these, the first
The member is preferably formed to exhibit higher resilience than the second member.

The above-described complicated form of the top of the first member can be obtained, for example, by applying a so-called profile processing to the elastic foam resin when the resin is employed.

An outer layer member made of an elastic material may be further laminated on at least one of the first member and the second member. The outer layer member is also formed of an elastic material. As the elastic material, as in the case of the first and second members, foamed resins such as foamed polyurethane, foamed polyethylene, foamed polypropylene, foamed polyvinyl chloride, various fiber structures, A combination of two or more of these can be exemplified.

Regardless of the material used for the outer layer, the above-mentioned second layer is used in order to comfortably use the rug.
It is preferable to use an elastic material having a resilience between the resilience of the member and the resilience of the first member.

The material of the outer layer member has a density of 18 k.
g / m ³ -28 kg / m ³ , hardness 80N-160N
An example is a degree of elastic foamed resin (typically, a general foamed polyurethane). Among them, it is desirable to form the first and second members so as to exhibit a rebound resilience between the rebound resilience of the first and second members.

When actually using the sleeping rug according to the present invention, the first member and the second member, or the outer layer member that is overlapped with at least one of the first member and the second member, is in a state where these members are laminated. The holding means may be held by a suitable holding means, and examples of such holding means include a flexible outer bag which holds and covers them in a laminated state.

Such an outer bag is preferably impermeable to water (impervious to water), but is preferably moisture permeable to keep the whole hygienic.

A plurality of sleeping rugs covered with an outer bag may be sequentially connected at the outer bag portion so that the rug can be developed and folded, and the unfoldable and foldable sleeping rug according to the present invention is also provided. Belongs to.

A sleeping rug covered with an outer bag and having a connecting tool in the outer bag so that a plurality of the rugs can be sequentially connected is also a rug according to the present invention. .

The rugs 20 and 30 can also be placed at desired places, for example, on the floor (eg, the floor of a room where a sick person is nursing), on the terrace of a building, on the lawn, on the ground (ground such as a beach or a river), on the poolside, in a car, or the like. It can be laid and used as a simple bed, or laid on a bed and used as a bed rug (bed mattress). Also, it can be used as a rug for leisure or the like by laying on a lawn, the ground (ground such as a beach or a river), a poolside, in a car, a boat, or the like.

The rug 20 can be used as a cushion or the like by further covering the entire rug 20 in a three-fold state or wrapping the whole in a bag or the like.

In any of the rugs 10 and 10 'described above, the rugs in which they are stored in a bag, and the rugs 20 and 30, if the rugs are laid on a desired place and the human body lies on them, etc. The weight of the human body is transmitted to the first member 1 via the second member 2. This transmission of the human body load
The concave streak portions 21 and 23 of the lower surface 2 ′ of the section 2 of the member 2
By being applied to the ridges 11 having a mountain-shaped cross section and the heads 121 of the ridges 12 having a mushroom cross-section, the heads of the ridges 11 having a mountain-shaped cross section and the mushroom-shaped ridges are formed. It is transmitted to 121 smoothly.

At this time, since the air gap S is left beside the lower part 122 which is continuous with the head 121 of the mushroom-shaped raised ridge, the portion of the mushroom-shaped raised ridge 12 to which a human body load is applied is the gap S It is easy to deform to S, more easily deformed than the raised ridge 11 having a mountain-shaped cross section, and can be compressed and deformed independently of the raised ridge 12 having another mushroom-shaped cross section and the raised ridge 11 having a mountain-shaped cross section. (See FIG. 5).

Thus, as a whole, the human body load is supported by the raised ridges 11 having a mountain-shaped cross section and the raised ridges 12 having a mushroom cross-section of the first member 1.
The part where the human body load is applied is deformed, and at that time, the part where the human body load is applied of the mushroom-shaped raised ridge 12 is easily compressed and deformed independently of other parts, so that each part of the human body is In accordance with the load applied to the rug, the top portions of the first member 1 corresponding to the load of each portion are smoothly recessed, and as a result, the reaction force applied to the human body portions from the rug is uniformized for the human body portions, and accordingly, on the rug. Comfortable and comfortable. Further, even when used by a sick person or the like for a long time, floor rubbing and the like hardly occur.

In the rug described above, since the first member 1 is formed of an elastic material, even if the rug installation surface has a step or unevenness, the rug is laminated on the lower surface of the first member 1 or on the lower surface thereof. It can be absorbed by the deformation of the outer layer member 3 which is used, and in this respect, it can be used comfortably.

In addition, the rug can be made relatively thin in a state having the above-mentioned structure for making the reaction force applied to each part of the human body from the rug uniform in each part of the human body. Thereby, it can be easily transported and moved and laid at a desired place and used as a simple bed, or laid on a bed and used as a bed rug (bed mattress). It can also be used as a rug for leisure or the like.

Further, the above-mentioned rug has a simple structure and can be manufactured at low cost.

Although an example has been described in which the first member is mainly used on the lower side and the second member is used on the upper side, the second member may be used on the lower side and the first member may be used on the upper side. Similar advantages are obtained.

[0059]

As described above, according to the present invention, compared with the conventional bed rug, the bulk is smaller, lighter, easily transported and moved, and the floor (for example, a room for nursing a sick person). Floor), on the terrace of the building, on the lawn, on the beach, poolside, in the car, etc., it can be used as a simple bed as it is, used as a rug for meals, rest, etc. It can also be laid on a bed and used as a bed rug. In addition, it is possible to provide a sleeping rug that can be manufactured at low cost because it suppresses the application of local and intensive reaction forces to a human body resting on it, thereby providing good sleeping comfort and simple structure.
