Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a futon dryer which can dry a futon in an unfolded state and can be folded and stored when not in use.

[Problems to be solved by conventional techniques and devices]

As shown in FIG. 4, for example, a conventional futon dryer has a structure of a central strut portion in which a strut pipe c, c and a short-length support pipe d, d are sandwiched by a pair of sandwiching members e, e. It was something to do. That is, the structure is such that the curved portions b are formed on the pair of strips a, a to form the sandwiching members e, e, and the pipes c, d are sandwiched between the inner surfaces of the curved portions b. Alternatively, the fifth
As shown in the figure, the resin molded products g, g are used as the sandwiching members e, e, and the pipes c ...
It was something that sandwiched ...

In FIG. 4, the pipes c ...
Since a large number of tightening screws and clamping members e, e capable of withstanding the tightening force are required for fixing the ... With frictional force, the number of parts is large and the cost is high, but the rigidity and strength are high. There was a problem of shortage. Further, in the case of the resin molding shown in FIG. 5, different types of resin molded articles g, g are required in accordance with the type of futon dryer having different numbers of pipes c ..., d. There was a problem that several expensive molds were required.

As a structure that eliminates the above-mentioned drawbacks of the structure of the central support,
There is one in which a strip plate a having a curved portion b ... As shown in FIG. However, this structure also requires a welding operation and has a problem in mass productivity. Welding work also has problems of welding distortion and rusting. Further, the strip plate a also requires a considerable thickness and width to prevent twisting.

Then, this invention aims at solving the said problem.

And a substantially W-shaped lower lateral member 15 in which a gentle upward curved portion 19 is formed in the center portion, and a rod shape in which the insertion portions 2 and 2 and the circumferential ridges 11 and 11 are formed at both ends. Vertical member 16 of
Composed of. The drying frame 1 includes an insertion portion 2 of a vertical member 16,
2, the upper and lower lateral members 14 and 15 are fitted into the inserted portions 17 and 17, respectively, and assembled into a substantially C-shape.

The central support column 3 is a pair of parallel rod-shaped support pipes 4,
4, a plurality of rod-shaped short-dimension support pipes 5 parallel to the support pipes 4, 4, and a pair of upper and lower first horizontal connecting rods 7, 7.
A pair of upper and lower second horizontal connecting rods 8 and 8 are provided. The upper and lower end portions of the pillar pipe 4 are provided with insertion portions 2 and 2, respectively.
Circumferential ridges 11 and 11 are continuously formed on the insertion portions 2 and 2. Similarly, the insertion portion 2 and the circumferential ridge 11 are also formed at one end of the support pipe 5. The inserted portions 17 of the drying frame 1 are fitted into the insertion portions 2 of the support pipes 4 and 4 and the support pipes 5. The drying frames 1 ... Are pivotally supported by the insertion portions 2 of the support pipes 4 and 4 and the support pipes 5 and 5 so that they can swing and open in the lateral direction.

FIG. 2 shows a detailed view of the main part of the structure of the central support column 3. The support pipes 4 and 4 and the support pipes 5 and 5 are connected by the first horizontal connecting rod 7 and the second horizontal connecting rod 8 so that their tips are aligned linearly. The first horizontal connecting rod 7 is a solid rod and is inserted into the base ends of the support pipes 5 and 5,
Caulking portions 6 are formed to fix the support pipes 5 and 5 at predetermined positions, and further, both ends of the caulking portions 6 and 4.
It is inserted inside 4. The second horizontal connecting rod 8 is a thin pipe, which is inserted into the tip ends of the support pipes 5 and 5, and further inserted into the vicinity of the tip ends of the support pipes 4 and 4.
It is fixed to the support pipes 4 and 4 with rivets 9.
Reference numeral 12 is a cylindrical spacer for keeping the interval between the pipes, and is attached to the second horizontal connecting rod 8 in an externally fitted shape. 13
Is a cap. The rivet 9 is the rivet body 20.
An example of an open-leg type that includes a driving member 10 and a driving member 10 is illustrated.

In order to assemble the central support column 3, first, the first horizontal connecting rod 7 is inserted into the holes 25 of the support pipes 5 and 5 in FIG.
By forming the caulking portion 6 on the connecting rod 7, the supporting pipes 5, 5
To fix. Next, attach the second horizontal connecting rod 8 to the spacer 12 ...
And the holes 24 of the support pipes 5 and 5 ... And
Both ends of the first horizontal connecting rod 7 are inserted into the holes 21 and 21 of the strut pipes 4 and 4, and both ends of the second horizontal connecting rod 8 are inserted into the holes 22 and 22. Finally, insert the rivet body 20, 20 into the small hole 23,
It is inserted into the hole of the second connecting rod 8 via 23, and the driving members 10, 10
Is driven into the rivet bodies 20 and 20, and the connecting rod 8 is fixed to the support pipes 4 and 4.

It should be noted that the present invention is not limited to the above-described embodiments, and design changes can be freely made without departing from the scope of the present invention. For example,
The positions of the first connecting rod 7 and the second connecting rod 8 may be interchanged vertically.

[Effect of device]

Since the present invention is configured as described above, it has the great practical effects described below.

Since the support pipes 5 and the support pipes 4 and 4 are skewered by the first horizontal connecting rods 7 and 7 and the second horizontal connecting rods 8 and 8, they can be firmly fixed, and the rigidity of the central support column 3 and The strength is high, unlike the case where the pipes 5 and 4 are fixed by frictional force such as sandwiching, the central strut portion 3 does not loosen or twist, and the structure can be simplified, The number of points can be reduced, the assembly is facilitated, and the inexpensive manufacturing is possible. Moreover, since the central support part 3 has almost no protrusion, the futon does not get caught during use,
Easy to use. Furthermore, by welding, the pipes 5, 4
Since it is not fixed, the productivity is good and the quality is not deteriorated due to welding distortion or burning. In addition, the first horizontal connecting rods 7, 7 are changed depending on the number of the support pipes 5 ...
Also, by simply changing the total length of the second horizontal connecting rods 8 and 8, it is possible to easily cope with the production of various kinds of futon dryers having different numbers of the drying frames 1 ..., which is economical.
