As described above, the necessity of cots used in the event of a disaster is widely recognized, and various items are distributed mainly made of corrugated cardboard, but due to their use, it is necessary to store a large number of them for a long period of time. Therefore, it should be manufactured at the lowest possible cost, and inevitably, the complexity of the shape and structure is not preferable. However, it is essential to ensure the strength to support the body safely, and in consideration of the confusion in the event of a disaster, a simple structure that can be easily understood should be introduced so that it can be assembled only by the personnel on the spot. Is.

The present invention has been developed based on such circumstances, and an object of the present invention is to provide a cot that can be manufactured at low cost, has sufficient strength, and can be easily assembled.

The invention according to claim 1 for solving the above-mentioned problems comprises a plurality of boxes and a reinforcing plate arranged upright inside each of the boxes, and the box is composed of four pieces. It has a side plate, one outer flap, one inner flap, and two inner flaps. The side plates are arranged in a rectangular shape in an upright position, and the inner flaps are placed on the upper part of the side plates. They are connected and arranged so as to face each other, and when the inner flaps are bent from the side plate, two facing sheets are vertically laminated, and the middle flap is connected to the upper part of the side plate and the inner flap is connected. The outer flap is connected to the upper part of the side plate and is arranged so as to face the middle flap, and when the outer flap is bent from the side plate, the entire upper part of the opening is opened. The reinforcing plate is a rectangular shape having the same length as the diagonal line of the box body and the same height as the box body, and the inner flap, the inner flap, and the outer flap of the inner flap, the inner flap, and the outer flap. In the fully folded state, these four pieces are stacked on the upper end surface of the reinforcing plate in a state of being stacked vertically, and a tongue piece protruding outward is formed on the tip surface of the outer flap, and the outer side thereof. A cot characterized by forming a slit at the base of the flap and connecting the boxes to each other by fitting the tongue piece and the slit to construct a bed at a position higher than the floor surface. Is.

The cot according to the present invention has a structure in which a plurality of boxes are gathered together to secure an area where a person can lie comfortably, and a reinforcing plate is arranged inside so that each box is not crushed by a load. There is. And the box body is a rectangular parallelepiped shape composed of four side plates and four flaps that close the opening at the top, similar to the widely used packaging box, and it is flat before use. Can be crushed. The reinforcing plate has a simple rectangular shape. Although corrugated cardboard is assumed as the material for both the box body and the reinforcing plate, various synthetic resin plates (such as corrugated plastic) can also be used.

The size of each box is flexible, but the height is about 40 cm due to its use, and the side is often about 30 cm to 50 cm when viewed from directly above, and this size is generally about "mandarin orange box" etc. It is equivalent to a packaging box called. A flap that closes the opening is provided on the upper part of the side plate that surrounds the box body. In the present invention, this flap is classified into three types: "outer flap", "middle flap", and "inner flap".

The inner flap is connected to the one having the shorter width among the four side plates of the box body, and inevitably two sheets are arranged so as to face each other across the opening of the box body. Moreover, when the inner flaps are bent at a right angle to the side plate (when the inner flaps are closed), the two inner flaps facing each other shall overlap each other up and down except for the base portion thereof. Therefore, the inner flap is clearly longer in overall length than the widely used packaging box.

The outer flap and the middle flap are connected to the longer side of the four side plates of the box body, and the one connected to one of the two side plates is called the outer flap, and the outer flap is also called the outer flap. The one facing the flap is called the middle flap. When each of the outer flap and the middle flap is bent, the middle flap is arranged downward, and the outer flap covers the outer flap. Further, the outer flap must be large enough to cover the entire upper part of the opening of the box body, and when the outer flap is bent, its tip surface shall reach the vicinity of the base of the middle flap.

The tongue piece is a plate-like object that protrudes like a tongue from a part of the tip surface of the outer flap (usually near the center), and plays a role of connecting two adjacent boxes. Then, in the box body, an elongated slit is formed at the base of the outer flap. Therefore, when the outer flap is bent, the tongue pieces and the slits are arranged so as to face each other, and after arranging a plurality of boxes adjacent to each other, the tongue pieces of one of the boxes are fitted into the slits of the other box. And the boxes are connected to each other.

If the tongue piece is simply fitted into the slit, the connection may be naturally released due to the deformation of each part. Therefore, the tongue piece may have a tapered trapezoidal shape, a small notch may be formed near the base of the tongue piece, and the maximum width of the tongue piece may be slightly longer than the slit. As a result, when the tongue piece is fitted into the slit, both ends of the slit are inserted into the notch near the base of the tongue piece, and the tongue piece can be held inseparably. The method of making the tongue piece inseparable is not limited to this.

Reinforcing plates are inserted inside the individual boxes and serve to support each of the folded flaps. This reinforcing plate has a simple rectangular shape, and its height is inevitably almost the same as the side plate of the box body. In addition, the length of the reinforcing plate is slightly shorter than the diagonal line inside the box body, and after being inserted inside, the range of movement is restricted by the side plate at the corner of the box body, and it naturally maintains an upright state. do. Therefore, the reinforcing plate exerts its function simply by inserting it inside. An inner flap is placed on the upper end surface of the reinforcing plate, and an inner flap and an outer flap are placed on the inner flap, so that the four layers of flaps are supported by the reinforcing plate. It is assumed that the reinforcing plate is placed on only one of the two diagonal lines inside the box.

In this way, the cot is composed of a box body and a reinforcing plate, and the reinforcing plate is inserted along the diagonal line inside the box body. In addition, each box body is provided with an inner flap, an inner flap, and an outer flap, and further, the outer flap. In addition to forming a tongue piece on the tip surface, a slit is formed at the base of the outer flap, and in a state where multiple boxes are lined up, the tongue piece of one of the boxes is fitted into the slit of the other box. Boxes can be connected to each other to construct a bed having a predetermined area.

The invention according to claim 2 relates to the configuration of each box body, and is characterized in that no flap is present on the bottom surface of the box body and the lower end surfaces of the side plate and the reinforcing plate are in contact with the floor surface. And. The box body is only for ensuring the height of the bed, and does not require the function of packing various items. Therefore, in the present invention, in addition to the lower end surface of the side plate of the box body, the lower end surface of the reinforcing plate directly contacts the floor surface without providing any flap for closing the bottom surface of the box body. As a result, the configuration of the box body is simplified.

As in the invention of claim 1, the cot is composed of a box body and a reinforcing plate, and the reinforcing plate is inserted along the diagonal line inside the box body. In addition, the inner flap, the inner flap and the outer flap are inserted into each box body. In addition to forming a tongue piece on the tip surface of the outer flap, a slit is formed at the base of the outer flap, and in a state where multiple boxes are lined up, the tongue piece of one box is used as the other box. By fitting it into the slit, the boxes are connected to each other, and a bed having a predetermined area can be constructed. Moreover, the sizes of the inner flap, middle flap, and outer flap are adjusted so that the four sheets are stacked and placed on the reinforcing plate, so the rigidity of the upper surface of the box is increased, deformation is less likely to occur, and it is vertical. Sufficient strength is ensured against the load.

In the present invention, since a plurality of boxes are connected to each other, each box has the same size as a widely used packaging box, and conventional equipment can be used for manufacturing the box. In addition, the reinforcing plate has an extremely simple rectangular shape and can be supplied at low cost. Further, the box body can be easily deformed into a flat surface like a widely used packaging box, and is excellent in storage and transportation. In addition, in the present invention, the bed is constructed only by opening the box body, inserting a reinforcing plate inside the box body, bending each flap, finally fitting the tongue piece into the slit, and connecting the box bodies to each other. This simple structure is easy to understand and can be easily assembled even in confused situations during a disaster.

As in the invention of claim 2, there is no flap on the bottom surface of the box body, and the lower end surfaces of the side plate and the reinforcing plate are brought into contact with the floor surface to simplify the configuration of the box body. , The amount of materials used such as corrugated cardboard can be reduced, the occupied space during storage is reduced, and the weight is reduced. It should be noted that such an advantage is only minor for individual boxes. However, the present invention needs to be stored in large quantities due to its use, and such an advantage is a feature that cannot be ignored.

It is a perspective view which shows the specific example of the cot according to this invention, the box body which constitutes this cot is drawn in the upper part of the figure, and the state which connected the box body to each other is drawn in the lower part of a figure. It is a perspective view which shows the internal structure of the box body of FIG. 1, the upper part of the figure is a state which the box body is halved, and the lower part of a figure is a state which a reinforcing plate is inserted into the inside of a box body. It is a perspective view showing the process of bending the inner flaps and the like after inserting the reinforcing plate into the inside of the box body of FIG. 1, the upper part of the figure is the state where the two inner flaps are bent, and the lower part of the figure is Furthermore, the middle flap is bent. It is a perspective view which shows the process of connecting the box bodies of FIG. It is a perspective view which shows the use method of the cot using the box body of FIG.

FIG. 1 shows a specific example of the cot according to the present invention. The upper part of the figure depicts the box 11 constituting the cot, and the lower part of the figure depicts the state in which the boxes 11 are connected to each other. be. The box body 11 has a rectangular parallelepiped shape similar to a widely used packaging box, is made of corrugated cardboard, and the upper surface of the connected box body 11 serves as a bed. Further, the side surface of each box body 11 is surrounded by four side plates 13, 14 and 15, of which the side plates 14 refer to two sheets located on the short side of the box body 11, and of course, this side plate The two are facing each other. The side plates 13 and 15 are located on the long side of the box body 11, and the side plates 13 and the side plates 15 face each other.

The upper part of the opening of the box body 11 is closed by the inner flap 24, the middle flap 23, and the outer flap 25. The inner flap 24 is connected to the upper part of the side plate 14 located on the short side of the box body 11, and a crease is made at the boundary between the two at the manufacturing stage so that the side plate 14 can be bent without difficulty. It has been formed. Further, the inner flaps 24 are arranged so that the two pieces face each other, but both of these two pieces have a length that can close more than half of the opening, and the two inner flaps 24 are arranged. When is bent at a substantially right angle, it will be stacked up and down except for the base part.

The middle flap 23 is connected to the upper part of the side plate 13 on the left side of the figure among the two side plates 13 and 15 located on the long side of the box body 11, and the side plate 13 can be bent without difficulty. A crease is formed at the boundary between the two during the manufacturing process so that it can be done. On the other hand, the outer flap 25 is connected to the upper part of the side plate 15 on the right side of the figure among the two side plates 13 and 15 located on the long side side of the box body 11, and this is also connected to the side plate 15 at the manufacturing stage. A crease is formed at the boundary of. Both the inner flap 23 and the outer flap 25 are sized to block almost the entire upper portion of the opening of the box body 11 by themselves.

An intermediate crease 27 is formed in the vicinity of the tip of the middle flap 23 at the manufacturing stage, and the region beyond that is referred to as a downward piece 28. When the intermediate crease 27 is actually bent, the downward piece 28 is projected to the right side of the figure, and then the base of the middle flap 23 is bent at a substantially right angle, the intermediate crease 27 is in the vicinity of the side plate 15 connected to the outer flap 25. The downward piece 28 faces the side plate 15 with a slight gap. As a result, the middle flap 23 and the side plate 15 come into contact with each other, thereby preventing the box body 11 from being crushed into a parallel quadrilateral shape and maintaining a rectangular parallelepiped shape. At the time of manufacturing the box body 11, the lengths (distance from the crease at the base to the tip surface) of the inner flap 24 and the middle flap 23 may be made equal so that the corrugated cardboard as a material can be used without waste.

At the center of the tip surface of the outer flap 25, a tongue piece 26 projecting outward from the tongue piece 26 is formed. Further, in the center of the base of the outer flap 25, a long and narrow slit 29 extending in the horizontal direction is formed. The tongue piece 26 and the slit 29 play a role of connecting the box bodies 11 to each other, and by fitting the tongue piece 26 of one box body 11 into the slit 29 of the other box body 11, both become inseparable. .. When the outer flap 25 is bent at a substantially right angle so that the tongue piece 26 can reach the slit 29 of the other box body 11 without difficulty, the size of the tongue piece 26 so as to protrude from the box body 11 (side plate 13). The arrangement has been adjusted.

After fitting the tongue piece 26 into the slit 29, it is not preferable that the tongue piece 26 naturally separates from the slit 29. Therefore, a semicircular notch is formed near the bases on both the left and right sides of the tongue piece 26, and both ends of the slit 29 are inserted into the notch to prevent the tongue piece 26 from coming off. The tongue piece 26 has a tapered trapezoidal shape in order to facilitate fitting into the slit 29. In addition, a cutout-shaped storage window 19 is formed on the side plate 13 connected to the middle flap 23. The storage window 19 plays a role of storing the tongue pieces 26 that are not involved in the connection between the box bodies 11, and is used because it is located in the front row when a plurality of box bodies 11 are connected.

The reinforcing plate 31 has a simple rectangular shape, and its width is slightly shorter than the diagonal line inside the box body 11. Therefore, when the reinforcing plate 31 is inserted into the inside of the box body 11, both left and right ends thereof are supported by the surrounding side plates 13, 14, and 15 to maintain an upright state. Further, the height of the reinforcing plate 31 is made equal to the height of the box body 11, and when the inner flap 24 is bent at a substantially right angle, the inner flap 24 is placed on the upper end surface of the reinforcing plate 31 and its drop is restricted. To. Further, when the inner flap 23 is placed on the inner flap 24 and the outer flap 25 is placed on the inner flap 23, the box body 11 is in a completely closed state.

Then, as shown in the lower part of FIG. 1, by fitting the tongue piece 26 into the slit 29, a plurality of boxes 11 can be connected in a row, and six boxes are connected in the direction connecting the lower left and the upper right in the figure. 11s are lined up, and by arranging two sets of these six boxes 11 in the width direction, the area required for a bed is secured, and a cot is completed. The boxes 11 adjacent to each other in the width direction of the cot (the side plates 14 thereof are adjacent to each other) are not physically connected to each other, but are simply adjacent to each other.

FIG. 2 shows the internal structure of the box body 11 of FIG. 1, the upper part of the figure shows the state in which the box body 11 is halved, and the lower part of the figure shows the reinforcing plate 31 inserted inside the box body 11. It is a state. As shown in this figure, there is no flap on the bottom surface of the box body 11, and the lower end surfaces of the side plates 13, 14 and 15 come into contact with the floor surface and the like as they are. Unlike the widely used packaging box, the box body 11 in the present invention does not require a function of packing various items, and such a structure can be introduced, and a corrugated cardboard or the like can be introduced accordingly. The amount of material used can be reduced. Since the flap is not present on the bottom surface of the box body 11, the strength of the box body 11 is reduced. However, the middle flap 23 prevents the upper part of the opening from being deformed, and the box body 11 has a rectangular parallelepiped shape. maintain.

The reinforcing plate 31 is arranged along the diagonal line inside the box body 11. Therefore, the left and right ends of the reinforcing plate 31 are adjacent to the side plates 13, 14, and 15, and the reinforcing plate 31 can inevitably maintain an upright state. As described above, since the reinforcing plate 31 is completed only by cutting out a material such as corrugated cardboard into a rectangular shape, the cost required for manufacturing can be minimized. In addition, the lower end surface of the reinforcing plate 31 also comes into contact with the floor surface or the like.

FIG. 3 shows a process of bending the inner flap 24 and the like after inserting the reinforcing plate 31 into the inside of the box body 11 of FIG. 1, and the upper part of the figure shows a state in which the two inner flaps 24 are bent. The lower part of the figure is a state in which the middle flap 23 is further bent. As shown in FIG. 2, after inserting the reinforcing plate 31 into the inside of the box body 11, first, the two inner flaps 24 are bent in order. Since the inner flap 24 has an appropriate size, the two inner flaps 24 are placed on the reinforcing plate 31 in a laminated state.

After bending the inner flap 24, the middle flap 23 is bent, but prior to that, the middle crease 27 of the middle flap 23 is bent, and the downward piece 28 is projected to the right side of the figure. Then, after the middle flap 23 is bent at a substantially right angle, the upper portion of the opening of the box body 11 is almost completely closed, and the downward piece 28 thereof is adjacent to the side plate 15 connected to the base of the outer flap 25. Therefore, in the upper part of the box body 11, the positional relationship between the side plates 13, 14 and 15 is restricted by the contact between the downward piece 28 and the side plate 15, and the rectangular parallelepiped shape is maintained. The intermediate crease 27 is formed at a position where the downward piece 28 can reach the vicinity of the side plate 15. However, in order to prevent the middle flap 23 from blocking the slit 29 and hindering the fitting of the tongue piece 26, some measures may be taken such as ensuring a slight gap between the downward piece 28 and the side plate 15.

FIG. 4 shows a process of connecting the boxes 11 of FIG. 1 to each other. When the outer flap 25 is bent after FIG. 3 above, the box body 11 has a perfect rectangular parallelepiped shape, but only the tongue piece 26 protrudes outward from the side plate 13. Further, when the individual boxes 11 are viewed from directly above in this state, a slit 29 is formed on the opposite side of the tongue piece 26. Then, when the two boxes 11 are brought close to each other and one tongue piece 26 is fitted into the other slit 29, the tongue piece 26 becomes inseparable from the slit 29, and the side plate 15 of the one box body 11 and the other box Both are connected in a state where the side plates 13 of the body 11 are in contact with each other.

Further, by preparing another box body 11 and repeating fitting of the tongue piece 26 and the slit 29, a plurality of box bodies 11 can be linearly connected as shown in the lower part of the figure. In the lower part of the figure, the tongue piece 26 of the box body 11 located on the leftmost side is not fitted into the slit 29. Therefore, only this tongue piece 26 is fitted into the storage window 19 located directly below to eliminate unnecessary protrusions.

FIG. 5 shows how to use the cot using the box body 11 of FIG. As shown in FIG. 4, the boxes 11 are connected to each other, and two sets of six are integrated. By arranging these two sets in the width direction, an area that can be used as a bed without problems is secured. The two sets arranged in the width direction are not physically connected just because they are adjacent to each other, but friction with the floor surface does not cause a practical problem.

When a plurality of box bodies 11 are only arranged side by side, there is a slight unevenness at the boundary portion thereof, which may cause discomfort to the user. To avoid this, a top plate 41 is placed on the upper surface of the box body 11. May be laid. The top plate 41 is a simple one made by cutting out corrugated cardboard or the like, but due to its size, it has a foldable structure. As described above, in the present invention, by making each box body 11 the same size as a "mandarin orange box" or the like, it is possible to reduce the manufacturing cost, and the method of connecting the box bodies 11 to each other is extremely simple, which is a disaster. It can be assembled without difficulty even at times.
