Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a futon dryer which is placed in a garden or the like of a general household for futon drying and can be folded and stored when not in use. A futon dryer constructed by using a steel pipe or other pipe materials is known as is found in, for example, Registered Design No. 360639. This invention is a foldable futon dryer, which improves its durability and makes it possible to smoothly and lightly perform folding or opening and closing operations, and at the same time prevent rainwater and the like from entering the inside of the pipe material. It is intended. Hereinafter, the present invention will be described with reference to the illustrated embodiments. 1 in the figure
Is a main pillar and is constituted by connecting two pipe members 1a and 1b at least at two upper and lower positions by a connecting fitting 2. Reference numeral 3 denotes a circular-cylindrical mandrel projecting upward or downward on the connecting fitting 2. In the figure, m represents the distance from the upper surface of the upper connecting fitting to the lower surface of the lower connecting fitting, and n represents the length by which the mandrel 3 projects from the connecting fitting 2. Reference numeral 4 denotes a frame body made of a steel pipe having a surface smoothed by chrome plating, and has a substantially C shape as a whole. That is, the frame body 4
Has an upper horizontal portion 5 and a lower horizontal portion 6, one end of which is connected by a columnar portion 7 and the other end is bent downward and upward to provide end portions 10 and 10, respectively. An opening 8 is formed between the end portions 10, 10. L is the length of the opening 8, which is slightly smaller than the metal fitting dimension m, preferably about 200 mm. In the embodiment, four such pipe material frame bodies are prepared, and their end portions 1
0 and 10 are fitted and pivotally supported on the outer surfaces of the upper and lower four mandrel 3, respectively. In addition, the number of the tubular member frame bodies 4 is not limited to four, but may be three or more. In addition, it is not always necessary to use a single material, and it is sufficient to connect a plurality of element pipes to form a substantially C-shape as a whole. In addition to the upper and lower two connecting fittings 2, as shown by 2a in the figure, it is also possible to connect at one or more places. In addition, the end portion 10 of the tubular frame body 4 and the core 3
As shown in FIG. 2, the fitting with and the case where the inner diameter of the end portion 10 is configured to be larger than the outer diameter of the upper and lower coaxial cores 3 as well as the lower core metal as shown in FIG. 3 may have a large diameter, and the outer diameter of the lower end portion 10 may be fitted to the inside thereof, and in this case, water infiltration into the pipe forming the frame body 4 can be better prevented.
FIG. 4 shows the outer surface of the lower connecting fitting 2 covered with a rubber cover 2b. As described above, the futon dryer of the present invention includes several pipe materials 1
a and 1b are connected to each other at least at two upper and lower positions by a connecting metal fitting 2 to form a main pillar 1, and a relatively short and small mandrel 3 is provided above the upper connecting metal fitting 2 and below the lower connecting metal fitting 2. In which the end portion 10 of the substantially C-shaped tubing frame body 4 is rotatably fitted to the mandrel 3 and is assembled,
The length L of the opening formed between the end portions 10, 10 of the frame-shaped tubular member 4 is smaller than the distance m from the upper surface of the upper coupling member 2 to the lower surface of the lower coupling member 2, The tubular frame 4 can be rotated around the mandrel 3 as an axis, and is expanded and expanded into a fan shape or the like as shown in FIG. Or, it can be folded and made compact to be easily stored. The opening 8 of the frame body 4 is formed to have a size smaller than the distance m between the connecting fittings 2 and 2 of the main pillar 1. Since a large gap is not formed in the pipe, the appearance is good, and in particular, there is little water immersion into the pipe from the lower end portion 10. Further, since the length of the end portion 10 of the frame body 4 is longer than the protruding length n of the cored bar 3, the end face of the end portion 10 is supported by the connecting fittings 2 and 2. Further, since the mandrel does not interfere with the bent portion between the horizontal portions 5 and 6 and the end portion 10, the opening / closing operation can be smoothly and lightly performed when the frame body 4 is rotated. It should be noted that if the number of the pipe members 1a and 1b of the main pillar 1 is smaller than the number of the frame bodies 4 as in the embodiment, it is possible to produce more advantageous effects such as light weight and inexpensive manufacturing.

Claims (1)

[Claims] [Claims] [Claim 1] Several pipes are connected to each other at least at two upper and lower positions by connecting metal fittings to form a main pillar, and above and below the upper connecting metal fitting. In a case where a relatively short mandrel is projected below the connecting fitting, and the end of the substantially C-shaped pipe material frame body is rotatably fitted to the mandrel, the mandrel is made of a substantially C-shaped pipe material. A folding futon, wherein the length of the opening formed between the ends of the frame is narrower than the distance from the upper surface of the upper connecting fitting to the lower surface of the lower connecting fitting. 2. The method according to claim 1, wherein the number of the pipe members is two, and four upper and lower cores are provided on the connecting member in a projecting manner.
Folding futon clothes with a frame made of individual pipes. 3. The folding futon dryer according to claim 1, wherein the substantially C-shaped pipe frame is formed by bending a single steel material. 4. The folding futon dryer according to claim 1, wherein the substantially C-shaped tubular material frame body is formed by combining several tubular materials.
