Description

[Detailed description of the invention]

0001

[Industrial Application Field] This invention allows a plurality of rectangular drying frames made of metal pipes or resin pipes to be expanded radially to dry futons, or folded and stored in a storage room. This invention relates to the improvement of a foldable futon dryer.

0002

[Prior Art] Hitherto, there have been a wide variety of futon drying devices of this type on the market (for example, the
Public Relations No. 22956).

[0003] Generally, futon dryers are made to be lightweight because they are often used by women in the household. However, since futon dryers are used outdoors, they sometimes fall over due to strong winds, staining the futons, and when not in use, the drying frame itself becomes dirty.

[0004] As an improvement measure for this problem, it is also practiced to place a weight on the futon drying device (for example,
However, this offsets the effect of making the futon dryer lightweight, and the weight had to be lifted and moved each time the futon dryer was moved, causing another problem.

[0005]

[Problem to be solved by the invention] The problem to be solved by the invention is that the futon drying device is intended to be used by women, so the futon drying device is lightweight and the drying frame can be expanded or folded. This happens as a reaction to being able to do this easily, and even if you take the futon dryer outside and set it up open as shown in Figure 1, one side will lift up due to strong winds and the drying frame will rotate in the folding direction. There is a reason for this.

[0006]

[Means for Solving the Problems] The present invention makes it possible to lock the drying frame once in the unfolded position in order to prevent the futon drying tool from tipping over, so that even if the futon drying tool is tilted by strong winds, the drying frame remains stable. The purpose is to prevent the drying frames 3 from being automatically folded, and consists of a plurality of drying frames 3 made of pipe material and shaped like a C, and a main body that rotatably supports the drying frames 3. The main column 2 is composed of an upper support member 2b and a lower support member 2c connected by a connecting vertical rod 2a, and the upper and lower support members 2b and 2c are rotatably connected to each other. At least two bottomed bearing members 4
. This was realized by providing a connecting member 9 that

[Embodiment] FIG. 1 shows an embodiment of the device of the present invention.
This is a futon drying device, and consists of a main pillar 2 and a plurality of substantially C-shaped drying frames 3 rotatably supported on the main pillar 2.

The main column 2 consists of an upper support member 2b and a lower support member 2c connected by two connecting vertical rods 2a, 2a. The upper support member 2b and the lower support member 2c have exactly the same shape and structure, and only their orientations are reversed. That is, the upper and lower support members 2b, 2
As shown in FIG. 2, C consists of two bottomed bearing members 4 disposed on the inside, and penetrating bearing members 5, 5 disposed on the outside sandwiching them. Both bearing members 4 and 5 are provided with an outer tongue piece 4a and an inner tongue piece 4b at symmetrical positions, and are pivotably connected to each other by inserting a pin 6 into a small hole bored therein. has been done. Note that the pin 6 may be fixed in the small hole in any manner, and the hole in either of the tongue pieces 4a, 4b may be machined to have a slightly smaller diameter than the pin 6 and then press-fitted. It is also possible to use a clip to prevent it from coming off. Thus, the main pillar 2 has connecting holes 7, 7 provided in the bearing members 5 of the upper and lower supporting members 2b, 2c.
It is constructed by press-fitting the connecting vertical rods 2a, 2a into.

The drying frame 3 is made by bending a steel pipe into a substantially C-shape. Here, the substantially C-shape means a frame made of a substantially rectangular pipe with a portion cut out, and means that the short ends are opposed to each other. More specifically, the drying frame 3 has a downward U-shaped piece 3a and an upward U-shaped piece 3b.
It consists of three sides formed by vertical members 3c that are loosely fitted to their ends, and the remaining one side is missing the center part, that is, there is no corresponding to the vertical member 3c, and it is U-shaped. It is constituted by short ends 3d, 3d formed by pieces 3a, 3b.

The connection between the main column 2 and the plurality of drying frames 3 is achieved through bearing holes 8, 8 provided in both bearing members 4, 5, respectively.
The short ends 3d, 3d of the shaped drying frame 3 are rotatably interlocked so that they can rotate smoothly.

The futon drying device 1 having such a structure can be stored in a storeroom or warehouse by folding each drying frame 3 from the state shown in FIG. At that time, the upper and lower support members 2b, 2c
are lined up in a straight line as shown in FIG. Conversely, if the drying frames 3 are expanded further until they form a cross shape, the bearing members 4 and 5 rotate around the pins 6, forming the corners of a substantially regular square, as shown in FIG. Gather at the department. In other words, drying frame 3
When expanding or folding the bearing members 4 and 5, the
The two positions are arranged in a straight line as shown in FIG. 3, and as shown in FIG.

The futon dryer 1 having such a structure can be stored by folding each drying frame 3 in the direction of arrow A from the state shown in FIG. At this time, the upper and lower support members 2b and 2c are aligned in a straight line as shown in FIG. Also,
When the bearing members 4 and 5 are further expanded in the direction of the arrow B and expanded into a cross shape, the bearing members 4 and 5 rotate around the pin 6 and come together at the corners of the substantially regular square. That is, when the drying frame 3 is expanded or folded, the bearing members 4 and 5 take a position where they are lined up in a straight line and a position where they are gathered in a rectangular shape, as shown in FIG. Note that the above configuration and operation are not much different from conventional ones that are commercially available.

[0013] Here, the present invention is applied to the state shown in FIG. 3 when the drying frame 3 is expanded, that is, the outermost bearing members 4 and
A connecting member 9 is provided in order to temporarily fix the relative position of the two in the folded state when the two are in a position closer to each other than in the folded state.

As shown in FIG. 3, the connecting member 9 is configured as a pin 9a that can be freely inserted and removed, directly connecting the outer tongue piece 4a and the inner tongue piece 4b of the outermost bearing members 4, 4. , or as shown in FIG. 4, the bearing member 4, via two connecting vertical rods 2a, 2a fixed to the bearing members 4,
It is configured as a hook-shaped member 9b that indirectly connects the parts 5 to 5.

That is, the pin 9a is attached to each bearing member 4, 5.
A small hole 4c made in the tongue pieces 4a and 4b for connecting the
It is made so that it can be inserted and removed from the 4D. That is, it is provided with a knob 9b that has approximately the same diameter as the pin 6 and is used to insert and remove it. The hook-shaped member 9b is made of a hard rubber-like material and includes a mounting portion 9d and an engaging portion 9e, and is loosely press-fitted into one of the connecting vertical bars 2a by the mounting portion 9d. Therefore, it can be moved up and down on the connecting vertical rod 2a by human power, and it can be temporarily stopped at the moved position by friction. The engaging portion 79 includes a recessed portion 9f that engages with the other connecting vertical rod 2a, and in the engaged state holds one connecting vertical rod 2a so as not to be separated from the other connecting vertical rod 2a. In order to engage the other connecting vertical rod 2a with this recess 9f, both connecting vertical rods 2a, 2a are slightly bent in the approaching direction when the drying frame 3 is in the open position. The same applies to the case of disengaging. The hook-shaped member 9b is effective in connecting the bearing members 4 and 5 using a thin plate made of synthetic resin or leather instead of a pin.

[0016]

Effects of the Invention As described above, the present invention allows the outermost bearing members 4, 4 to be directly and indirectly connected and fixed by the connecting member 9 in the open state of the drying frame 3, and to be automatically folded. Therefore, even if one side of the futon dryer is lifted up by strong winds, the problem of the drying frame 3 being folded and falling over is eliminated. When the connection member 9 is disengaged, it can be folded and stored in the same way as in the conventional case. Furthermore, the structure is simple and can be provided at low cost.
