Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an inflatable pneumatic table that is used to float on the surface of water in pools, hot springs, etc.

[Conventional technology]

Conventionally, an air table has been known, for example, from Japanese Utility Model Application Publication No. 109702/1983, which is constructed by constructing a polygonal bag-like body using, for example, a synthetic resin sheet and injecting air into the bag-like body.

[Problem that the invention attempts to solve]

However, this type of table does not have a cylindrical cup with an open top inside the table body, a concave part for holding out bottles, etc., so when using the table floating on the water surface, for example, the same table cannot be used. If the above-mentioned cups, bottles, etc. placed on top are unstable, there is a risk that they may easily fall over, especially if the water surface is rippled and the table shakes. It was hot.

[Means for solving problems]

In this invention, a large number of holes are formed in the top plate made of a thermoplastic soft synthetic resin sheet, and a concave portion made of a thermoplastic soft synthetic resin sheet is formed below the holes in a donut shape with the same inner diameter as each hole. The half members are superimposed and the inner peripheral edge of each upper half member is hermetically welded to the incisal edge of each hole, and a lower half member for forming a recess made of a thermoplastic soft synthetic resin sheet is attached to the underside of each upper half member. The entire outer circumferential edges of the upper and lower half members are welded to each other airtightly, and the upper plate is polymerized onto the circular lower plate made of a soft thermoplastic synthetic resin sheet. The bottom plate and the lower half member mentioned above are airtightly welded to each other at locations on the circular line, and air supply/exhaust plugs are attached to the required locations of the annular side plate made of a thermoplastic soft synthetic resin sheet, and this side plate is The upper edge of the side plate and the outer periphery of the lower plate are interposed between the upper plate and the lower plate, and the lower edge of the same side plate and the outer periphery of the lower plate are airtightly fused to each other. The above-mentioned problems are solved by providing a table consisting of a table, and when the whole is inflated by supplying air from the supply/exhaust valve, a concave part with an opening at the top for holding a tip, bottle, etc. is formed. This is what I did.

〔Example〕

In order to explain the embodiment of the present invention in accordance with the manufacturing method, first, a large hole 2 is formed at the center of a circular top plate 1 made of a transparent thermoplastic soft synthetic resin sheet, and small holes 3 are formed at numerous locations around the periphery. holes 2 and 3 below each of the large hole 2 and small hole 3.
The upper half members 4 and 5 for forming a recess made of opaque thermoplastic soft synthetic resin sheets having a donut shape with the same inner diameter are overlapped, and the inner peripheral edge of each upper half member 4 and 5 is connected to the incisal edge of each hole 2 and 3. air-tightly high-frequency welded.

Thereafter, lower half members 6 and 7 for forming recesses made of an opaque thermoplastic soft synthetic resin sheet are superimposed on the lower side of each upper half member 4 and 5 to form the upper half members 4 and 5 and the lower half member 6. , 7 are hermetically welded together.

Next, the above-mentioned upper plate 1 is superposed on a circular lower plate 8 made of an opaque thermoplastic soft synthetic resin sheet,
This lower plate 8 and the lower half members 6, 7 are hermetically welded to each other at a circular point 9.

After that, separately from these, both ends of a band-shaped plate made of an opaque thermoplastic soft synthetic resin sheet are welded together using high frequency to form an annular side plate 10, and the side plate 10 is blown and vented to required locations. At the same time as installing the plug 11, this side plate 10 is inserted between the above-mentioned upper surface plate 1 and lower surface plate 8, and the upper edge of the side plate 10, the outer peripheral edge of the upper surface plate 1, and the lower side edge of the same side plate 10. The outer peripheral edges of the upper and lower plates 8 are airtightly welded to each other by high frequency welding, and the main part 12 of the air-filled table, which can be expanded and contracted to take on a disk shape when expanded, and the cylindrical cup having the above-mentioned small hole 3 as an opening are formed. , a table is completed which is provided with a recess 13 for holding bottles, etc., and a cylindrical ice cooler recess 14 having the above-mentioned large hole 2 as an opening.

[Functions and effects of the invention]

Since the present invention is as described above, it goes without saying that when air is blown into the air supply/exhaust valve attached to the side plate, the whole body expands into a board shape and can be floated horizontally. By mutually welding the upper plate with the opening, the upper half member for forming the recess, the lower half member and the lower plate, etc., when the whole expands as described above, the top plate with the open top can be used to insert a cup, bottle, etc. A concave portion is formed, which allows the tip,
This makes it possible to stably place bottles and the like on a table, thereby completely solving the above-mentioned problems of the present invention.
