It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed. Quot; is defined only by the scope of the claims set forth below. Therefore, the definition should be based on the contents throughout this specification.

Throughout the specification, when an element is referred to as "comprising ", it means that it can include other elements as well, without excluding other elements unless specifically stated otherwise.

1 is a perspective view of a portable bed according to an embodiment of the present invention. Referring to FIG. 1, the portable bed of the present invention may be composed of a mattress 100 and a plurality of cases 400. The mattress 100 may be wrinkled on its outer surface and may contract or expand due to external forces. This form may be desirable to have a bellows shape. Also, the mattress 100 can be made of rubber and the outer surface can be brushed. A mattress made of rubber material with a soft brushed can produce a fluffy effect like a waterbed. The case 400 may be divided into a first case 401 and a second case 402 and the first case 401 or the second case 402 may be located on both sides of the mattress 100.

The present invention is also applicable to any one of a pair of cases that can be divided into the first case 401 and the second case 402. Hereinafter, the case 400 will be referred to. If only the case 400 is indicated, it may be the first case 401 or the second case 402.

The first case 401 and the second case 402 may be coupled to both sides of the mattress 100 to seal the inside of the mattress 100.

2 is a perspective view of a case of a portable bed according to an embodiment of the present invention. 2, the case 400 may include a suction unit 200 through which air flows into the mattress 100 and a discharge unit 300 through which the air inside the mattress 100 is discharged.

The number and position of formation of the suction unit 200 and the discharge unit 300 are not particularly limited. For example, the first case 401 or the second case 402 may have at least one suction unit The discharge unit may be formed, or at least one suction unit may be formed in the first case 401, or at least one discharge unit may be formed in the second case 402.

FIG. 3 is a state in which a suction portion and a discharge portion of a portable bed according to an embodiment of the present invention are opened. FIG. 4 is an exploded view of a suction portion and a discharge portion of a portable bed according to an embodiment of the present invention. 3 and 4, the suction unit 200 may include an inlet 210, a suction net 220, an inlet valve 230, and an inlet stopper 240.

The suction unit 200 may include a suction port 210 formed in at least one of the plurality of cases 400 and may be installed at the suction port 210 so that the suction port 210 is opened when the mattress 100 is inflated. And a suction port valve 230 for closing the suction port 210 when the mattress 100 is contracted.

The suction port 210 is a hole formed in the case 400 and external air can be introduced into the mattress 100 through the suction port 210. The suction port 220 may be mounted on the suction port 210. When the suction net 220 enters the inside of the mattress 100, the suction net 220 serves to prevent external foreign matter that may damage the mattress. The mesh size of the suction net 220 is not limited and is not particularly limited as long as it can prevent foreign matter.

Since the inlet valve plate 230 can be installed on the inner side of the mattress 100 case 400 and the inlet valve plate 230 is larger than the diameter of the inlet 210 and can be opened only from the outside to the inside, When the force (air pressure) is applied to the outside from the suction port 210, the suction port 210 may block the suction port 210 due to a shape larger than the suction port 210.

The outlet 300 may include an outlet 310, a discharge net 320, an outlet valve 330, and an outlet cap 340.

The discharge unit 300 may include a discharge port 310 formed in at least one of the plurality of cases 400 and may be installed at the discharge port 310 so as to discharge the discharge port 310 when the mattress 100 is retracted. And an outlet valve 330 for closing the outlet 310 when the mattress 100 is inflated.

The discharge port 310 is a hole formed in the case 400 and the air inside the mattress 100 can be discharged to the outside through the discharge port 310. A discharge net 220 may be mounted on the discharge port 310. The discharge net 220 serves to prevent external foreign matter that may be damaged when the inside of the mattress 100 enters. The mesh size of the discharge net 220 is not limited and is not particularly limited as long as it can prevent foreign matter.

The outlet valve plate 330 may be installed on the outer side of the mattress 100 case 400 and the outlet valve plate 330 may be larger than the diameter of the outlet 310 and open only in the outward direction. When the force (air pressure) is applied to the inside of the discharge port 310, the discharge port 310 can be blocked due to a shape larger than the discharge port 310.

Finally, the outlet cap 340 can seal the outlet from the outside. Grooves may be formed in the periphery of the discharge port 310 so as to be fitted in the grooves, or may be sealed by inserting into the discharge port without grooves.

5 is a state diagram showing a state in which the portable bed according to the embodiment of the present invention is inflated. Referring to FIG. 5, the principle of expanding the mattress 100 will be described. When the compressed portable bed is unfolded, the corrugated portion of the mattress 100 is expanded and the internal volume of the mattress 100 is increased. As the inner volume increases, the air pressure inside the mattress 100 becomes lower than the outside air pressure. So that external air can be introduced into the interior of the mattress 100. The suction valve plate 230 can be opened by the air entering from the outside to the inside due to the force of lifting from the outside to the inside and the outlet valve plate 330 can be more strongly closed.

When the mattress 100 is continuously inflated, the outside air continues to flow into the inside, and the outlet can not be opened because the air that has already entered the inside is greater in pressure than the pressure that the outside air exits through the outlet. Further, by closing the outlet cap 240 at the outlet, it is possible to block even the only passage that can be discharged.

The inflated mattress 100 does not become larger once it is above a certain volume. Therefore, there is a need to air more than a certain volume artificially. 6 and 7, FIG. 6 is a view illustrating a pump of a portable bed according to an embodiment of the present invention. Referring to FIG. 6 (b), the pump 530 may be coupled to the suction port 210. The pump 530 may be used to artificially inject air.

6 (c), when the pump 530 is compressed, the upper surface of the pump 530 may be flattened, thereby replacing the suction port plug 240. 6 (a) shows a state where the pump 530 is coupled to the suction port 210 and used.

In addition to the pump 530, there may be another embodiment. 7 is a perspective view of a portable bed and a blower according to an embodiment of the present invention. Referring to FIG. 7 (a), there may be a vent cap that can be coupled to the blow- The one end of the blower cap can be hermetically coupled to the blowing port, and the other end thereof can be coupled to the blower 520. The blower 520 shown in FIG. 7 is generally a blower 520 available on the market, and is not particularly limited as long as it is an apparatus capable of injecting air, not a blower 520 shown in FIG.

The mattress 100 may be further inflated by injecting air into the mattress 100 by coupling the airflow 500 to the inlet 210 as shown in FIG. 7 (b). A state of the mattress 100 filled with air is shown in Fig. 8 is a perspective view of a portable bed according to an embodiment of the present invention. The portable bed having the installation completed can seal the suction part and the discharge part by inserting the suction port stopper 240 and the discharge stopper 340 into the suction part 200 and the discharge part 300. The air inside the mattress 100 is not discharged while the user uses the portable bed.

It is the same principle to rearrange after using the portable bed. 9 is a state diagram showing a state in which the portable bed is compressed according to an embodiment of the present invention. Referring to FIG. 9, when the mattress 100 is compressed, the mattress can be folded according to the folds of the mattress, and the volume of the mattress 100 is reduced while being folded. Since the mattress 100 having a reduced volume internally has a higher air pressure than the outside air pressure, air tends to be naturally discharged from the inside to the outside. Accordingly, when the discharge stopper 340 is removed and the mattress 100 is compressed, the air inside the discharge port 310 is discharged to the outside.

On the other hand, the mattress 100 may include a zipper 600.

10 is a perspective view of a portable bed to which a zipper is applied according to another embodiment of the present invention.
