Description

Detailed Description of the Invention

  The present invention relates to a simple toilet that is composed of a plastic sheet such as vinyl or polyurethane and is inflated with air.

Conventionally, there have been simple toilets made of plastic products and corrugated paper, but patent publication numbers 2002-165728, 2006-149966, and 2007-44356 are products made of synthetic resin material or cardboard and are not disassembled or folded. Even if it can, it is still unsuitable for carrying, and the cardboard simple toilet bowl lacks water resistance and strength. In addition, although there were some Omar for infants made of vinyl, there was the inconvenience that a separate plastic bag was fitted on the bottom and an air pump was prepared. Also, resistance to the air injection in the mouth was felt only for the waste. Similarly, Patent Publications 2000-37322, 7-194500, and registered utility model 3031348 use air bags, but the air chambers are separated and air pumps must be prepared, and each air injection is complicated. there were.

Problems to be solved by the invention

  The present invention is intended to be developed so as to be convenient to carry, and to make the air injection method simple and sanitary when used, except for its drawbacks.

Means for solving the problem

Now, the solution means will be described with reference to the drawings. (A) The seat is hollow and formed into an annular shape, and the backrest 1 is provided on the outer periphery thereof. (B) The air of FIG. Provide a valve.
(C) The air valve shown in FIG. 4 is also provided at the bottom inside the backrest.
By constituting as described above and raising and lowering the backrest part 1 by hand, the role of an air pump is provided. The connecting portion of the toilet seat 5, which is the upper portion of the backrest portion and the annular portion 6, has an air inlet and is connected inside.
(D) Move the backrest up and down, put air in the main body, and then use it after attaching a shopping bag or garbage bag to the main body.

Form of the actual state of the invention

  The present invention has the above structure, and pushes down the locking portion 13 of the air valve in FIG. In addition, it is desirable to further provide an air plug 4 as shown in the figure and use it for exhausting air. The air plug 4 is a plug used for a general air vinyl toy, a floating ring or the like. When injecting air, open the lid 9 of the air hole 2 after opening the lid of the air hole 2, hold the handle 3 under the backrest with one hand, and move the backrest 1 up and down to inject air. Can be inflated easily. Further, the air pump 7 may be formed in a protruding shape on the outer periphery of the main body even if it is not a backrest as shown in FIG. The structure of the annular portion is a structure in which air is injected and held therein, and if it has strength, it may be divided vertically as shown in FIG. 1 or horizontally as shown in FIG.

  The configuration of the air pump is sufficient if the valve is provided at two or more locations on the upper and lower sides, and the main body can be formed quickly and easily by forming the whole structure with one air chamber together with the main body annular portion. Explaining the air valve at the upper end of the protrusion in FIG. 3, the upper part of the valve 12 is drilled and welded to the upper surface of the main body backrest 1. The two air holes have one through hole in the center, and also have several through holes around it. The valve shown in FIG. 5 is suspended by a locking portion 13 in the central through hole. The movable valve 10 in FIG. 5 is a soft sheet and is made of rubber or resin. The air taken in from the upper side pushes down the movable valve 10 and causes air to flow into the inside. The same applies to the air valve of FIG. 4 attached to the bottom of the inner bottom of the pump. The once taken-in air pushes up the movable valve 10 'of FIG. 4 from the inside and comes into close contact with the lower surface 11 of the air valve, so that no air leakage occurs. 3 and 4 basically have the same structure, and FIG. 3 only includes the lid 9 integrally. The lower portion of the air valve 11 is curved upward to prevent contact with the movable valve 10 in which rubber or a sheet is punched, thereby increasing the surface area.

  The configuration of the air pump may be a pair of upper and lower air valves, but it may further have two upper parts or two lower parts. In addition to the above, various types of air valve structures are possible. FIG. 6 has a movable valve 16 at the bottom of the main body 15 and a stopper 14. FIG. 7 shows the internal structure of another air pump, which has an air valve 3 in the upper part, is composed of a foamed elastic body 18 and a sheet of its locking part 17 in the lower part, and the cylinder is in the side part. It has 20 shaped valves. The cylindrical sheet spreads in a cylindrical shape when air flows in, but after that, it is crushed by the internal air pressure and stops discharging air. The structure of the air pump need not be via a sponge, and may be an internal structure in which a tubular sheet is directly connected to the lower portion as shown in FIG. In FIG. 8, a slit is provided in the lower portion to prevent the tube from sticking, but a hole may be formed on one side. It is also effective for preventing sticking to have a sand-like texture on the inner surface of the tube.

  In carrying out the present invention, a plastic bag such as a relatively small supermarket is used, and a handle portion that does not allow air to enter on the opposite side of the backrest as shown in FIG. As shown in FIG. 9, if the bag is placed in the center of the main unit after being hooked on the handle and the backrest, it can be used as a simple toilet for infants. When the bag is large, it is also effective to weld the hook 8 to the front part of the main body and hook it. Placing a urine adsorbent used in disposable diapers in advance inside the bag makes it easier to clean up. For adults, the main body should be large and a large garbage bag should be stored inside. Further, in the embodiment of the present invention, a hole may be made in the ground in the event of an earthquake or disaster, and filth may be put out directly inside the hole without using a bag. Since it is inflated with air, it is soft to use, and when folded, it is light and easy to carry without taking up space.

With respect to the configuration having the bottom portion in the main body of the second aspect, if a sheet that does not contain air is welded as the bottom, it is flat, easy to clean and easy to manufacture.
In order to have a structure that allows air to enter the bottom, an L-shaped hard pipe is welded to the lower part of the main body annular portion 6, one end of the pipe is exposed, and then inserted into a hollow bottom opening, and the periphery is hermetically sealed. By doing so, the whole can be configured with a single chamber. By having a bottom, even if a plastic bag or the like is torn, filth remains inside the simple toilet, so the room does not have to be soiled.

The invention's effect

    Since the air pump is formed integrally with the main body, the simple toilet can be inflated easily and hygienically anywhere without using an air pump or injecting air from the mouth. After use, it can be carried by removing the air. Moreover, since a shopping bag, a garbage bag, etc. can also be accommodated in the inside, rear-cleaning is easy, and since the main body is pneumatic, the feeling of use is also soft. Also useful in the event of an earthquake or disaster.
