Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an air inflatable body with an air filling device, such as a rubber boat or an air pine tress, which has a built-in air filling device for filling the inside with air.

[Conventional technology]

There are many types of air inflatable objects that are inflated by filling them with air, such as rubber boats, air pine tresses, mini pools, aquariums, and floats, which can be used at home or carried to the sea or mountains. and use it. When filling this type of air inflatable body with air, for small ones such as air pillows and floating rings, air is blown into the air through the air inlet, but for larger ones such as rubber boats and air pine tresses, In some cases, air is filled by connecting and operating a separately provided air filling device. Conventionally used air filling devices of this type have a compression coil spring interposed between a pair of plates connected by a bellows so that they can be opened and closed, and a compression coil spring that biases one plate in the opening direction. It is a bellows-type device with an intake port and an exhaust port with on-off valves attached to the bellows.By stepping on and releasing a plate, the bellows expands and contracts repeatedly, opening and closing both on-off valves and filling the air with air. Ru.

[Problem that the invention attempts to solve]

However, since these conventional air filling devices are provided separately from the air inflatable body, it is a hassle to forget where to put them and look for them, and when carrying them outdoors, the heavy and bulky air filling device has to be used as a main body. It becomes luggage because it has to be carried separately from the
If you had no choice but to carry only the main unit, you would have to fill it with air orally, which would increase your fatigue.

[Means for solving problems]

In order to solve such problems, the present invention provides a hollow airtight bag-like elastic film body that blocks off a part of the main body air chamber of the air inflatable body to be filled with air, and the outer cover of the body is made of an elastic material. In addition to integrally forming the chamber, an intake port with an on-off valve was attached to the membrane body, and an exhaust port with an on-off valve was attached to the partition wall between the membrane body and the main body air chamber.

[Effect]

When air is blown into the air chamber and sealed, or when the air inlet is closed, the membrane elastically returns and expands while sucking in air from the air inlet, so pushing and releasing the membrane causes its expansion and compression. When repeating the above steps, the air sucked into the membrane body by opening the inlet opening/closing valve opens the exhaust opening opening/closing valve and fills the air expandable body. Furthermore, since the air filling device is built into the main body of the air inflatable body, it will not dissipate or become a burden when being carried.

〔Example〕

This embodiment shows an example in which the present invention is applied to a rubber boat. Fig. 1 is a perspective view of the rubber boat, Fig. 2 is a perspective view of the vicinity of the air filling device, Fig. 3 is a partially cutaway plan view, and Fig. 4 a, b are an exploded sectional view of the intake port and an exploded sectional view of the exhaust port, respectively; Fig. 5 a, b, c
FIGS. 6a, 6b, and 6c are a plan view of the entire air filling device and an enlarged sectional view of the intake port and the exhaust port, respectively, shown for explaining the air filling operation. In the figure, an air pump 1 as an air filling device is equipped with a membrane body 3 formed in the shape of a hollow sealed bag from an elastic material such as rubber or plastic. A plurality of air chambers 33 are formed with a double structure of an outer membrane 31 and an inner membrane 32, and one of them is equipped with an air blowing port 30 that can be opened and closed by rotation. When the air inlet 30 is opened, the air chamber 3
3. Therefore, the entire membrane body 3 is flat and can be folded. Furthermore, when air is blown into the air chambers 33 by attaching the mouth to the open air blowing port 30, all the air chambers 33 expand at the same time, giving the membrane body 3 an elastic return force to the expanded state. It is configured to inflate. After inflation, the air inlet 30 is closed.

The membrane body 3 formed in this manner is provided so as to block a part of the U-shaped air chamber 2 formed in the rubber boat 6 as an air expansion body. That is, both end surfaces of the membrane body 3 serve as partition walls that partition the membrane body 3 and the air chamber 2, and the circumferential surface of the membrane body 3 has the same shape as the circumferential surface of the air chamber 2. The peripheral surface of the membrane body 3, the membrane body 3, and the air chamber 2
The threaded portions of an intake port, generally designated by reference numeral 7, and an exhaust port, designated by reference numeral 5, are hermetically screwed into a screw hole of a cap provided in one of the partition walls between the intake ports 7 and 7. The exhaust port 5 and the exhaust port 5 have the same structure, and the main body is formed of a guide pipe having a flange 51, and a valve seat 52 is provided in the inner hole thereof. Reference numeral 54 denotes a disc-shaped valve body made of an elastic material, which is inserted into the guide pipe through a groove 53 provided adjacent to the valve seat 52 and fixed by press-fitting a filler 55 into the groove 52. The valve seat 52 is configured to open and close by elastic deformation due to air pressure. Note that the valve body 54 of the intake port 7 opens toward the membrane body 3, and the valve body 54 of the exhaust port 5 opens toward the air chamber 2.
Open inward. By doing this, when the membrane body 3 expanded by filling the air chamber 33 is pushed, the valve body 54 of the intake port 7 closes and the valve body 54 of the exhaust port 5 opens, so that the inside of the membrane body 3 is Air is exhausted from the exhaust port 5. When the user releases his/her hand from this state, the membrane body 33 elastically returns and expands while sucking the atmosphere through the valve element 54 of the open intake port 7. In this case, the valve body 54 of the exhaust port 5 is closed by the air pressure within the membrane body 3. The reference numeral 211 in FIG. 1 is an air vent for the air chamber 2.

The operation of the rubber boat with an air filling device configured as above will be explained. When the air inlet 30 of the air pump 1 is opened, the air in the air chamber 33 is released, and when the air vent 21 is opened, the air in the air chamber 2 is released, so the entire rubber boat 6 can be flattened and carried outdoors. . In this way, for example, when filling air into the rubber boat 6 carried to the sea, after closing the air vent 21, blowing air through the open air blowing port 30 with your mouth will remove all the air that communicates with each other. When the chamber 33 is filled with air, the membrane body 3 elastically returns and expands while sucking atmospheric air through the valve element 54 of the intake port 7, and the air inlet 31 is closed in this state. Therefore, as shown in FIG. 5, when the membrane 3 is grasped with one hand or held between both hands and pushed, the air inside the membrane 3 is compressed, and the air pressure closes the valve body 54 of the intake port 7. As shown in FIG. 5c, the valve body 54 of the exhaust port 5 opens, and the compressed air moves into the air chamber 2 of the rubber boat 6 through the valve opening. When the pressure on the membrane body 3 is released from this state, the valve body 54 of the exhaust port 5 closes due to the air pressure in the air chamber 2, as shown in FIG.
As shown in FIG. b, the valve element 54 of the open air inlet 7 elastically returns and expands while sucking in the atmosphere. By repeating the compression and expansion of the membrane body 3 in this manner, the rubber boat 6 is filled with air.

FIG. 7 is a perspective view of an air mattress with an air filling device showing another embodiment of the present invention.
is provided at one corner of the air pinerest 60.
That is, the air chamber 2 of the air pinerest 60 is blocked by partition walls on two sides of the membrane body 3, and the partition wall on the end surface side in the longitudinal direction is provided with the exhaust port 5 of the above embodiment.
An exhaust port (not shown) with the same on-off valve is provided. Further, an air intake port 8 with an on-off valve, which is the same as the air intake port 7 of the above embodiment, is attached to the outer end surface of the membrane body 3, and an air chamber formed in the outer cover of the membrane body 3 is provided with an air intake port 8. A blow-in port 40 is attached. With this configuration, when the air chamber 2 is filled with air and the membrane body 3 is pushed and released to repeat compression and expansion, the air chamber 2 of the air pine tress 60 is filled with air. is the same as in the previous embodiment. 31 is an air inlet for the air chamber 2.

In each of the above embodiments, a rubber boat and an air mattress were exemplified as the air inflatable body with an air filling device according to the present invention, but the present invention can also be applied to various air inflatable bodies such as an air bed, a mini pool, and an aquarium. can do.

[Effect of idea]

As is clear from the above explanation, according to the present invention, a hollow airtight bag-shaped elastic film body is provided to block a part of the main body air chamber of the air inflatable body, the inside of which is filled with air. In addition to integrally forming an air chamber on the cover, an intake port with an on-off valve is attached to the membrane body, and an exhaust port with an on-off valve is attached to the partition wall between the membrane body and the main body air chamber to compress the membrane body. By repeatedly inflating the air chamber, air can be filled into the air chamber, making it easy to fill the air chamber.Since the air filling device is built into the air inflatable body and is always integrated with the air chamber, it is possible to It is convenient because you can use it immediately without having to search for it when filling. Furthermore, when storing the air inflatable body or carrying it outdoors, the membrane body can be folded together with the air inflatable body by removing the air from the air chamber of the air filling device.
