Description

[Detailed Description of the Invention] This invention relates to a futon dryer that can be placed in the garden of a general household and used for drying futons, and can also be folded and stored when it is inconvenient.It has a simplified structure and is lightweight. The purpose of this is to improve the appearance of the product, as well as to make it easier to fold or expand the product.

Hitherto, futon drying devices constructed using pipe materials have been known, for example, as shown in Registered Design No. 36063y. Ta. This invention eliminates such problems. The present invention will be explained below with reference to the embodiments shown in the drawings.

In the figure, 1 is the main pillar, which is made of two steel pipes la and lb. The exchange materials la and lb are connected at least in two places, upper and lower, by an upper connecting fitting 2 and a lower connecting fitting 3. 4 is the upper connecting fitting 2 facing upward, or the lower connecting fitting 3
It is a cylindrical metal core that protrudes downward from the top.

The same number of mandrels 4 are protruded from the upper surface of the upper connecting fitting 2 and the lower surface of the lower connecting fitting 3, respectively, and the upper and lower two pieces form a pair.

Two pairs of them are the main metal cores 4a and 4b, and the pipe material la
, lb. In this embodiment, the main metal cores 4a and 4b connect the upper and lower parts of the pipes la and lb to each connecting metal fitting 2.
, 3 and are integrally constructed so as to protrude above or below.
The other two pairs are auxiliary mandrels 4a and 4b, and the pipe materials la and lb
In the embodiment, for example, two pairs of grooves are additionally provided between the grooves. In this way, four pairs of upper and lower mandrels are formed. Reference numeral 5 denotes a frame made of pipe material, which is formed by bending a single steel pipe to form a substantially quadrilateral shape as a whole, with the center portion of one side thereof being cut off.

That is, the frame 5 connects one end of the upper horizontal part 6 and the lower horizontal part 7 by the columnar part 8, and also connects the upper and lower horizontal parts 6, 7.
The other ends are bent downward and upward, respectively, to form opposing parts 9,9.
are provided, and a closed portion 11 is formed between them. L is the length of the opening 11, which is the same as or slightly smaller than the dimension m between the upper and lower connecting fittings 2 and 3, preferably about 20 mm smaller.

In this embodiment, four such pipe frame bodies 5 are prepared, and their open □ parts 11 are iron-fitted to the outer light parts of the above-mentioned four upper and lower pairs of ○ metals 4, 4, and are rotatably connected. be.

Note that the number of the pipe frame bodies 5 does not necessarily have to be four, and it is sufficient to have three or more in order to make the futon dryer stand on its own on the ground.

Further, it is not necessarily necessary to form a single piece of material by bending it, but for convenience of manufacturing or transportation, a plurality of raw pipes may be connected to form a substantially quadrilateral shape as a whole. In addition, connecting fittings 2
, 3 can be connected not only at the upper and lower two but also at one or several locations as shown by 10 in the figure.

Furthermore, as shown in FIG. 2, the outer diameter of the upper and lower concentric rings 4 is smaller than the inner diameter of the opposing part 9 when the opposing part 9 of the tubular frame 5 and the mandrel are fitted together. In other cases, the diameter may be large as shown in FIG. In FIG. 4, the outer surface of the lower connecting fitting 3 is covered with a rubber cover 3b.

In this case, water intrusion into the frame 5 can be better prevented. Therefore, the frame 5 rotates around the main mandrel 4a and the auxiliary mandrel 4b, and can be expanded and made to stand on its own and used by covering the upper horizontal part 6 with a futon, or can be folded down to a small size and stored indoors or in a storage room. It is something to do. As described above, in the futon drying device of the present invention, the main pillar is formed by connecting at least two pipes vertically with the upper connecting fitting and the lower connecting fitting, and the upper connecting fitting 2 and the lower connecting fitting In a device in which a relatively short and small mandrel 4 is provided protruding from the lower surface of the metal fitting 3, the mandrel 4 is
It is composed of two pairs of upper and lower main mandrels 4a disposed coaxially with the main pipe materials la and lb, and at least one pair of auxiliary mandrels 4b additionally installed between them. A substantially quadrilateral tube frame 5 having a closed portion 11 therebetween is engaged with each other, and the tube frame 5 has a pair of upper and lower mandrels 4, 4 protruding from the upper and lower connecting fittings 2, 3. It can be rotated around the axis.

Therefore, the number of tubes la constituting the main pillar 1 is greater than the number of frames 5.
Since the number of lbs can be reduced, the weight of the futon dryer can be reduced, and even relatively weak homemakers, such as housewives, can easily take it out to the garden or store it in a shed.It also has a simpler appearance, Improves aesthetic appearance.

Moreover, since the tubes la and lb are connected and reinforced by the connecting fittings 2 and 3, the strength is not impaired in any way even if the number of tubes la and lb is small. In addition, since the tube frame 5 is simply fitted into a short metal core, there is less friction and smooth operation is achieved. In addition, if the opening □ part 11 of the frame body 5 is formed with a small opening equal to the distance m between the connecting metal fittings 2 and 3 of the main column 1, the end 9 of each frame body 5 and the connecting metal fitting 2, Since there is no large gap between the pipe and the pipe, the appearance is further improved, and there is little water intrusion into the pipe, especially from the lower end part 9.

Furthermore, by making the length of the end 9 of the frame 5 longer than the protruding length n of the mandrel 4, the mandrel will not interfere with the bending part between the horizontal parts 6, 7 and the end 9. , the frame body 5 can be rotated smoothly. Moreover, if the ends of the tubes la and lb constituting the main pillar are made to protrude from the connecting fitting, they can be used as the main metal core, and the structure is simplified. Furthermore, if the frame is assembled into a substantially quadrilateral shape by combining a plurality of elongated blank tubes, the disassembled state of the frame can be housed in an elongated case, facilitating storage and transportation.
