Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to air struts/columns for air structures, ie, air domes using sheets or the like. An air dome with an open entrance/exit cannot be created unless a part of the structure is supported by air, but the problems in this case are as follows.

It cannot be supported unless the air support is large. This is because the support and other parts are made of the same material, so it is not possible to build up much pressure.

The adhesive area is large and time-consuming, and this area often causes air leaks and damage.

It is difficult to find the location of the air leak, and if a part of the air leaks, it is easy to make the whole unit unusable.

When using auxiliary strings to make the seat stand upright, stress tends to concentrate at the contact points between the seat and the strings.

In addition, for those with independent air struts, the treatment at both ends of the color is messy, which can easily cause air leaks, and there are thin tubes that connect the tubes to send air. , since it is removed from the side of the seat cylinder, it is cumbersome to manufacture, and air tends to leak from that part.

In order to improve these points, the present invention first separates the air struts from the tent part and makes them look like independent structural members, and the air struts are connected by pipes at their ends so that air can be sent to each strut. In Nishide, we made it possible to construct the frame of a structure using only air struts. The tent sheet is either placed over the structure or assembled by passing air struts through a number of tunnels made of fabric or sheets within the sheet. Both ends of the pillar can be connected in various ways using special joints. This pillar is easy to mass produce in a factory, and the internal pressure can be raised considerably, so it is extremely light.
It can be a strong pillar.

Specifically, it is as follows: 1. A tube 1 made of a flexible sheet-like material has cylindrical side portions that fit into both ends of the tube to facilitate airtight contact. On the lid,
At least two small holes 3 for letting air in and out are provided,
and a protrusion 4 that fits into the joint 6 that connects the columns.
The air strut 2 is characterized in that the above-mentioned lid 2 is made of synthetic resin, and the small hole 3 and the protruding portion 4 are integrally molded. , the air strut 4 according to claim 1 has an ear portion 5 with a hole for passing a string or the like on the side of the lid or on the edge so as not to interfere with the adhesion of the sheet, and the small hole 3 is a vinyl tube or the like. The second part is attached so that it can be easily attached and detached. As shown in Figure 4, the air strut 5 is provided in a small protrusion, the aforementioned small protrusion is provided in a recessed hole (Fig. 5), and the air strut 6 is installed in a small hole 3. , the air strut 7 according to claim 1 has a tunnel shape (FIG. 6) in which a thin vinyl tube or the like is inserted and bonded. The air strut 8 according to claim 1, which has a fire-like shape (FIGS. 2 to 8), and the claim in which the above-mentioned protrusion 4 has a non-circular cross section (FIG. 8) In the air strut 9 described in item 1, the cylindrical side surface has a step in the middle and the diameter becomes slightly smaller (
Figure 9) Insert a separately made ring into that part,
The air strut 10 according to claim 1 is characterized in that a cylindrical sheet is adhesively fixed between the two, and a reinforcing band 8 is attached in a helical shape to the portion of the sheet tube into which air enters (No. 10).
Figure) is an air strut 11 according to claim 1, the sheet cylinder is a seam, and the air strut according to claim $ 1 is a cylinder with no adhesive part. Fig. 1 shows the main strut and its connection state. A perspective view of the figure is shown. 6 is a joint, and 7 is a vinyl tube that serves as an air passage.

FIG. 2 is a perspective view of the end of the sheet cylinder, and FIG. 4 is a sectional view thereof. In this case, as stated in claim 2, since it is made of plastic of appropriate hardness, the small hole 3 that connects to the vinyl tube, the protrusion 4 that fits into the joint,
Furthermore, in order to prevent the fitted joints from coming off, holes with holes 5 for tying the pillars together with a string or the like can be molded in one piece. Figure 3 shows various joints, and those drawn in black are the method of connecting by inserting them into the hole in the lid.In order to prevent the protrusion 4 and the joint 6 from coming apart, Another method is to drill a pin hole and attach it with a bolt. This method becomes especially necessary when the lid is made of metal or the like with a large support. Fig. 5 is a sectional view of the protrusion connecting the thin tubes that has been retracted inside to prevent breakage, and Fig. 6 is a type in which the thin tubes are inserted into the holes and glued together. Figure 7 is a plan view of the lid, Figure 8
In the figure, the cross section of the protruding part 4 that connects to the joint is not circular.When combined with this kind of joint, the air strut will rotate firmly by adding a step to the circular part on the side of the lid. The sheet is fitted with a separately made ring and fixed with adhesive. In this case, it is advisable to attach the holed ears described in item 3 to this ring. In Figure 10, a strong helical band is attached to the support column so that higher-pressure air can be fed. The obi can also be attached in a ring shape, but that part is more susceptible to bending. Claim No. 11
The item listed in this section is the most ideal cylindrical sheet for use in the present invention, and requires a special manufacturing method. Generally, a sheet does not become strong unless it is stretched, so this is made by extruding it into a thin tube, pumping air into it, inflating it within the tube of the required thickness, and simultaneously pulling it.

Figure t511 is an example of a structure made with this support, and 9 is an atto balloon that prevents the dome ceiling from falling downward.

If the support of the present invention is made with standardized support sizes and handles, it can be easily replaced and is easy to use. At that time, we also provide parts that cut and connect thin tubes, and parts that prevent unused small holes. A compressor is also required to pump air into the main column. When the structure of the present invention is deflated, it can be stored extremely small, and the framework can be easily disassembled if necessary. One of the advantages is that even in the unlikely event of an emergency, air can only escape through the small holes, so there is no need to worry about air escaping.

Overall, the outline of the air strut of the present invention is that the end of the cylinder sheet is treated in a natural shape as a cylinder, and that part is made of a relatively hard material, so that the protrusion can be taken out from the t. The protrusions concentrate force in a small area, allowing the columns to connect together, and the hard parts can be easily used to create air inlets and outlets, as well as parts for attaching auxiliary lobes.
