<P>PROBLEM TO BE SOLVED: To provide a clothes drying implement capable of preventing denting crush or bending injury on the inner side of a bending part in a frame having the bending part and composed of pipes disposed parallel when used. <P>SOLUTION: The cross-sectional shape of pipes constituting the frame 10 having the bending part 11 and composed of the pipes disposed parallel when used is vertically long oval, so that the difference between the outer circumference and inner circumference in the bending part is reduced. As a rib 10r extending in the horizontal direction is disposed within each pipe 10, a dent in a space within the pipe can be prevented. As the bottom surface 12 of the pipe 10 is flat, holes 13 for hanging clothespins can be easily and accurately bored with a drill. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

  The present invention relates to a clothesline. More specifically, it relates to the cross-sectional shape of the frame.

As a conventional clothes-drying tool, for example, a clothes-drying tool as found in Patent Document 1 is known. Explaining with reference to the reference, this clothesliner includes a frame (10) having a bent portion made of a pipe (12), which is arranged in a horizontal direction when used.
According to such a clothes-drying tool, a frame can be configured simply by bending a pipe, and therefore a frame that is excellent in strength to some extent can be obtained with a simple configuration.
However, such a conventional clothesline has a circular cross-sectional shape of the pipe. For this reason, when bending the pipe, due to contact with a bending jig, etc., as shown in FIG. It had the difficulty of being easy. Such concave crushing and bending scratches are easily caused by the circular cross-sectional shape of the pipe, and at the same time have the drawback of being conspicuous in appearance.

Japanese Patent No. 4127388

  The problem to be solved by the present invention is to provide a clothes-drying tool that is arranged in a horizontal direction during use, and that is unlikely to cause concave crushing or bending damage inside the bent portion of the frame having a bent portion made of a pipe. is there.

In order to solve the above-mentioned problems, the clothes-drying tool of the present invention is a clothes-drying device provided with a frame having a bent portion made of a pipe, which is horizontally disposed when used,
The cross-sectional shape of the pipe constituting the frame is an oval long in the vertical direction.
According to this clothes drying tool, the cross-sectional shape of the pipe constituting the frame is an oblong shape that is long in the vertical direction. Therefore, when bending the pipe, the length of the outer circumference and the inner circumference of the bent portion in the circumferential direction is long. The difference in thickness is smaller than when the pipe cross section is circular.
Therefore, compared to the conventional case, concave crushing and bending damage are less likely to occur inside the bent portion.
In addition, the cross-sectional shape of the pipes that make up the frame is an oblong shape that is long in the vertical direction, so the strength against twisting about the horizontal axis required when using the clothes-drying tool is higher than that of a circular cross-section. Relatively improved.
Therefore, it is possible to obtain a clothes drying tool which is relatively light and has a large torsional strength and is easy to use as compared with the prior art.
Preferably, a rib extending in the horizontal direction is provided inside the pipe.
In this case, the presence of the rib makes it difficult for the inside of the pipe to be deformed toward the outside, and therefore, the crushing of the concave shape on the inside of the bent portion is further less likely to occur.
Preferably, the bottom surface of the pipe is a plane.
If it does in this way, since the drilling process using the drill to a frame bottom face can be performed now easily, the hole at the time of hanging a pinch can be processed easily.

Hereinafter, embodiments of a clothesliner according to the present invention will be described with reference to the drawings.
As shown in FIG. 1, this clothes-drying tool 1 is a clothes-drying tool including a frame 10 having a bent portion 11 made of a pipe, which is arranged in a horizontal direction when in use, and a cross-sectional shape of a pipe constituting the frame 10 Is characterized by an oval shape that is long in the vertical direction.

  In the embodiment shown in FIGS. 1A to 1E, the hole 13 for suspending the pinch 20 (see FIGS. 2 and 5) from the bottom surface 12 of the frame 10 can be easily machined, that is, The bottom surface 12 of the pipe is flat so that drilling can be easily performed. However, when it is not necessary to provide the pinch 20 on the frame 10, it is not necessary to provide the hole 13, and therefore, it is not necessary to make the bottom surface 12 flat. Therefore, as shown in FIG. The cross-sectional shape of the pipe that constitutes can be an ellipse that is long in the vertical direction (an ellipse whose bottom is not a flat surface).

  As shown in FIGS. 1 and 2, the clothes-drying tool 1 according to this embodiment includes a frame (hereinafter also referred to as a main frame) 10, a plurality of pinches 20 connected to a lower portion of the main frame 10, A suspension frame 30 for suspending the main frame 10 is provided. The main frame 10 and the suspension frame 30 are connected by hinge portions 40, 40.

The main frame 10 is provided in a pair of left and right, and constitutes a track-like frame in plan view as the entire left and right.
The pipe constituting the main frame 10 is a metal pipe (for example, an aluminum pipe or a stainless steel pipe). This metal pipe can be produced by a known production method (for example, extrusion molding or drawing (drawing) production method), and the main frame 10 can be produced by bending the pipe using a jig.

In the embodiment shown in FIGS. 1A to 1E, as described above, the bottom surface 12 of the main frame 10 is a flat surface, and there are a plurality of holes 13 for hanging the pinch 20 (this embodiment). In this case, 16 pieces are provided for each frame.
The plurality of holes 13 are formed by arranging the bent main frame 10 on the machine tool as shown in FIG. 3, for example, and using the same number of drills D as the holes 13 (16 in this embodiment). They can be formed in one batch by a single drilling process.

  As shown in FIG. 1, a hook 31 is rotatably provided on the top of the suspension frame 30, and the clothes drying tool 1 can be hung from a hanging basket or the like (not shown) with the hook 31. Reference numeral 32 denotes a ring-shaped handle provided coaxially with the hook 31 and can be grasped by hand when hanging the clothes-drying tool 1 on a clothes-drying basket or the like.

  The hinge 40 is connected to an end 33 of the suspension frame 30 and a first joint member 41 connected to the end 33 so as to be pivotable in the vertical direction in FIG. And a second joint member 42. The first joint members 41 and 42 are configured in a point-symmetric manner in a plan view, and are respectively cylindrical connecting portions 41b and 42b into which end portions 14 (see FIG. 3) of the main frame 10 are fitted, and the connecting portions. 41b (42b) and the disc part 41c (42c) integral. The disc portions 41c and 42c are pivotally connected to the shaft portion formed by the end portion 33 of the suspension frame 30 so that the first joint members 41 and 42 are respectively connected to the end portion 33 of the suspension frame 30. The left and right main frames 10 can be folded toward the hook 31 as shown in FIG. 4 when they are not used.

As shown in FIG. 5, the pinch 20 can be suspended from the main frame 10 by a suspension member 50.
The suspension member 50 has a suspension fitting 51 and a connecting member 52.
The hanging metal fitting 51 is composed of a single spring member, and has a substantially ring-shaped part (hereinafter referred to as a ring part) 51r and a hook part 51f on the upper part for hanging on the main frame 10. Yes. The hanging bracket 51 can be attached to the main frame 10 by returning the hook portion 51f to its original position due to the spring property of the hook portion 51f after the hook portion 51f is inserted into the hole 13 of the main frame 10 so as to narrow its width.
The pinch 20 is suspended from the ring portion 51r via the connecting member 52. As the connecting member 52, a known metal ring can be used. The connecting member 52 connects the ring portion 51 r of the hanging metal fitting 51 and the spring 21 of the pinch 20.

According to the clothes drying tool as described above, the following effects can be obtained.
(A) Since the cross-sectional shape of the pipes constituting the frame 10 is an oblong shape that is long in the vertical direction, for example, as shown in FIG. Thus, when bending is performed, the difference in the length in the circumferential direction between the outer periphery 11b and the inner periphery 11c of the bent portion 11 (the difference caused by the difference between the curvature radius Rb of the outer periphery 11b and the curvature radius Rc of the inner periphery 11c) , Smaller than when the cross section is circular.
That is, for example, as shown in FIG. 6B, the cross section is in the vertical direction as shown in FIG. 6C, compared to the difference Rb′−Rc ′ between the radii of curvature Rb ′ and Rc ′ when the cross section is circular as shown in FIG. The difference Rb-Rc between the radii of curvature Rb and Rc in the case of a long oval is particularly small.
Therefore, compared to the conventional case, concave crushing and bending scratches are less likely to occur on the inner side 11c of the bent portion 11. In particular, when the pipe is made of aluminum, the conventional configuration is likely to cause a concave crushing or bending damage. However, according to this embodiment, even if the pipe is made of aluminum, the concave crushing or bending Scratches are less likely to occur. Therefore, the present invention is particularly effective when the frame 10 is made of an aluminum pipe.
Moreover, since the cross-sectional shape of the pipe constituting the frame 10 is an oval shape that is long in the vertical direction, the strength against the twist T about the horizontal axis required when using the clothes drying tool 1 shown in FIG. Compared to a circular shape, the relative improvement is achieved.
Therefore, it is possible to obtain a clothes drying tool which is relatively light and has a large torsional strength and is easy to use as compared with the prior art.

(B) Since the bottom surface 12 of the pipe (10) is a flat surface, the drilling process using the drill D to the frame bottom surface 12 can be easily performed. Therefore, the hole 13 when the pinch 20 is suspended can be easily processed.
For example, as shown in FIG. 7A, if the surface to be drilled with the drill D is curved, the teeth of the drill D can easily escape along the curved surface as indicated by arrows. Therefore, the position of the hole is easily shifted or the shape of the hole is easily deformed, and it is difficult to make an appropriate hole at an appropriate position. The same applies to the case of a circular cross section as shown in FIG.
On the other hand, according to this embodiment, as shown in FIG. 7B, since the bottom surface 12 of the pipe (10) is a flat surface, the teeth of the drill D are difficult to escape. Therefore, it becomes easy to make a proper hole at a proper position. The same effect can be obtained when the bottom surface of the pipe having a circular cross section is flat as shown in FIG.

<Modification>
FIGS. 8A and 8B are cross-sectional views showing modifications of the frame 10.
The frame 10 shown in FIG. 8A is provided with a single rib 10r extending in the horizontal direction inside the pipe constituting the frame 10, and the frame 10 shown in FIG. Two 10r are provided. The rib 10r is a plate-like body extending in the longitudinal direction of the pipe, and is formed integrally with the inner surface of the pipe when the pipe is manufactured.
With this configuration, the presence of the rib 10r makes it difficult for the inside of the pipe to be deformed outward (that is, the space inside the pipe is difficult to be recessed). For this reason, it becomes difficult to produce the concave crushing inside a bending part.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and can be appropriately modified within the scope of the gist of the present invention.
