Abstract

PURPOSE:To easily combine three or more air bags in specific connecting constitution by mutually connecting three or more air bags arranged radially at the connection parts of the centers thereof and separating the respective air bags outside said connection parts to form spaces. CONSTITUTION:In a support 1 assuming the shape of a Christmas tree, three air bags 2, 3 arranged radially are mutually connected at the connection parts 4 of the centers thereof and separated outside said connection parts 4 to form spaces 5. Various Christmas ornaments are hung from the support 1. The integrally molded one of two air bags 2 and one air bag 3 are prepared. Each of the air bags 2, 3 is prepared by superposing two vinyl sheets 6 one upon another and inserting a plug 7 in the sheets 6 and sealing the parts becoming the outer peripheries of the air bags 2, 3 and the outer peripheral part of the plug 7. Among the seal parts 8 of both air bags 2, 3, the contact part of them becomes an integral connection part 8a.

Description

[Detailed Description of the Invention] Purpose of the Invention [Field of Industrial Application] This invention relates to an air bag connection body used as a support for ornaments such as Christmas trees and various ornaments, and various air bag connections including the support. This invention relates to a method for connecting air bladders in the body.

[Prior art and problems to be solved by the invention] Conventionally,
There are no Christmas trees or other ornaments that use air bladders as supports.

Air bags are lightweight and convenient to carry, and can be folded up when not in use, so they do not become bulky when stored. However, the shape of the support varies depending on the purpose, and it is necessary to enhance the decorative effect. Therefore, it is difficult to manufacture a strut using only one air bladder.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to combine three or more air bags in a specific connection configuration, so that the air bag can be used for various purposes and can also enhance the decorative effect. The purpose is to provide a connector.

Another object of the present invention is to provide a connection method that can easily manufacture a connection body for each air bag.

Structure of the invention [Means for solving the vR problem] In order to achieve this object, the air bag connected body of the present invention has three air bags arranged radially as shown in the drawings of the first and second embodiments described later. The above air bags 2.3 are connected to each other at the connecting part 4 at the center, and each air bag 2.3 is connected to the outside of this connecting part 4.
3 to form a space 5, and when three air bags 2.3 are arranged radially around the connection part 4 as shown in the drawing of the first embodiment, one One side edge 9a of the air bag 3 and the integral connection part 8a between the two integrally molded air bags 2 are overlapped and connected to each other, and
When four air bags 2 are arranged radially around the connection part 4, the integral connection part 8a between the two integrally molded air bags 2 and another similar integral connection part 8a are stacked on top of each other. Connect.

Note that even when five or more air bags are arranged radially around their connecting portions, both of the above connection methods become part of the process.

[Function] For example, when the present invention is used for a Christmas tree support as shown in the drawing of the first embodiment, each air bag 2, 3
By using the space 5 created in between, more various Christmas decorations can be displayed.

Furthermore, as shown in the drawings of the second embodiment, when the present invention is used as a prop for an ornament, a decorative cover 1 is placed on the outside of the prop 1.
0, the decorative cover 10 is stretched along the line connecting the tip edges 2a of each air bag 2, and the decorative cover 10 does not partially inflate due to the expansion of each air bag 2. No more damage to the external design.

[First Example] First, a first example in which the present invention is applied to a Christmas tree support will be described with reference to FIGS. 1 to 14.

As shown in Figures 1 to 3, the support 1 shaped like a Christmas tree has three air bags 2.3 arranged radially.
are connected to each other at a central connection 4, and this connection 4
The air bags 2.3 are separated from each other on the outer side to form a space 5. As shown in FIG. 4, various Christmas decorations are hung on this support 1.

This support column 1 is manufactured as follows.

First, two air bags 2 are integrally molded as shown in Figures 5 and 6, and one air bag 3 is molded as shown in Figure 7.8.
and manufacture.

Either air bladder 2.3 is shown in Figure 9.10 or Figure 11.1.
As shown in FIG. 2, it is manufactured by overlapping two vinyl sheets 6, inserting a stopper 7, and sealing the outer periphery of each air bag 2.3 and the outer periphery of the stopper 7. Of the seal portions 8 of both air bags 2, the portion where they come into contact becomes an integral connection portion 8a.

Next, as shown in Fig. 13.14, one side edge 9a of the seal 8119 of one air bag 3 and the integral connection part 8a between the two integrally molded air bags 2 are overlapped and connected. do. In this way, the three air bladders 2.3 are arranged radially around the connecting portion 4 thereof.

In the strut 1 configured in this way, a space 5 is created between the air bags 2 and 3 when air is injected, so compared to a case where there is no such space 5, various Christmas decorations can be placed in this space. You can use the space 5 to decorate more items.

Therefore, the decorative effect can be enhanced. Moreover, since it is lightweight, it is convenient to carry. Furthermore, when not in use, the air can be removed from the stopper 7 and the support 1 can be folded up.
It does not get too hot when stored.

Moreover, such a support 1 can be easily constructed by the above-described procedure.

[Second Example] Next, a second example in which the present invention is used as a prop for an ornament will be described as a first example.
This will be explained according to FIGS. 5 to 21.

As shown in FIGS. 15 to 17, in the strut 1, four air bags 2 arranged radially are connected to each other at a connecting part 4 at the center, and the air bags 2 are connected to each other outside the connecting part 4. They are separated to form a space 5. And the 18th and 19th
As shown in the figure, a decorative cover 10 is provided on the outside of this support 1.
is covered.

This support column 1 is manufactured as follows.

First, as in the case shown in FIGS. 5 and 6 of the first embodiment, a pair of integrally molded air bags 2 is manufactured.

Next, as shown in FIGS. 20 and 21, the integral connecting part 8a between the two integrally molded air bags 2 and another similar integral connecting part 8a are overlapped and connected. In this way, the four air bags 2 are arranged radially around the connecting portion 4.

In the strut 1 configured in this way, since a space 5 is created between each air bag 2 when air is injected, a decorative cover 10 is stretched along a line connecting the tip edges 2a of each air bag 2, and each The decoration cover 10 is not partially expanded due to the expansion of the air bag 2, and the pattern on the outer surface of the decoration cover 10 is not damaged. Therefore, the decorative effect can be enhanced. Moreover, since it is lightweight, it is convenient to carry. Furthermore, when not in use, air can be removed from the stopper 7 and the support 1 can be folded up, so that it does not become taut when stored.

Further, such a support column 1 can be easily manufactured by the above-described procedure.

In addition, in addition to the two actual flow sides, when five or more air bladders are arranged radially around their connecting portions, the method of connecting the two actual bladders becomes a part of the process.

Effects of the Invention According to the air bag connected body for a column of a decorative article according to the present invention, it can be applied to various purposes and the decorative effect can be enhanced.

Further, according to the method for connecting each air bag according to the present invention, each air bag can be easily connected.
