Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to the field of futon drying.

[Conventional technology]

Conventional futon drying methods include Utility Model Application No. 63-202286, Utility Model Application No. 62-43595, Utility Model Application No. 59-193389, and Japanese Unexamined Utility Model Application No. 193389.
As seen in Publication No. 62-295677, etc., the insertion member that supports the bent rear end of the upper hook rod and the bent rear end of the lower support rod in a convergent manner is constructed similarly. The rear ends of both rods inserted into these fitting members were simply inserted.

Furthermore, in a device disclosed in Japanese Utility Model Application Publication No. 59-139265, protrusions were provided on the upper and lower surfaces of the connector, and the ends of the openings of the drying rods were engaged with these protrusions.

[The problem that the idea aims to solve]

The conventional insertion member for futon drying is simply inserting or engaging the bent rear end of the upper hanging rod and the bent rear end of the lower support rod. The rear end was very easy to slip out or pop out.

In other words, unlike clothing, a futon has a relatively large capacity, and when the futon is removed from a hanging state, the rear end where the upper hanging rod is inserted is pulled in the same direction as the futon is pulled up. ,
This is because the result will be that it will come off depending on the situation.
In addition, when the futon drying rod is assembled by connecting the upper hooking rod, the front connecting rod, and the lower supporting rod and is formed into an approximately C shape, the weight of the hung futon,
The bent rear end of the upper hanging rod protrudes from the insertion part, which distorts the shape of the entire futon drying rod and causes the respective connection points to come off.

Therefore, the present invention has developed a mechanism that, unlike conventional insertion members, once assembled, the inserted end of the futon drying rod does not easily come out, and there is no risk of it popping out. It is.

[Means to solve the problem]

After fitting it in a sandwich shape, it is tightened and fixed using a tightening tool. When the pair of connecting members are assembled as a set as described above, the upper hooking rod will not easily come off.

Therefore, the same applies to the lower support rod.

On the other hand, in the case of the connecting member of the second embodiment, when the bent rear end of the upper hook rod is inserted, the flap-like opening is inserted into the fitting insertion part for preventing the stopper from popping out. It is prevented from flying out. Then, the other symmetrical connecting member is fitted in a sandwich shape and fixed via a fastener. When a pair of connecting members are assembled as a set as described above,
The upper hook rod does not come off easily.

Therefore, the same applies to the lower support rod.

As described above, the connecting body has a symmetrical shape.
Since the pair of connecting members are formed by plastic molding or pressing, and then matched and tightened in a sandwich-like manner, they are extremely firmly fixed once assembled.
