The width of the arc-shaped rib 23 of the second joint portion 20 described later is such that the linear rib 14 is directed toward the peripheral portion 18, that is, the direction away from the main body frame 1, with the virtual center line 10 h extending in the horizontal direction as a lower side. It is connected in sequence with the length exceeding the limit.

In the above structure, the wall 16 on which the conventional contact wall is to be formed above the first joint portion 10 is, for example, a virtual vertical center line 10P and a peripheral portion 18 in front view of FIG.
From the starting point of intersection with the body frame 1.

Alternatively, if the holding body 10 and the holding body 20 constituting the first and second joints (not shown) are provided with a large diameter that is continuous with the upper ridge line of the main body frame 1, the upper wall surface of the joint is provided. No need.

If the fillet 19 is provided on the inner peripheral edge of the holding body 11, the work can be performed more smoothly when the joint is connected.

On the other hand, the second joint portion 20 has a thickness extending from the main body frame 1 so as to be interposed between the interleaving bodies 11, and a fitting projection which can be fitted into the fitting hole 12 at the center of both sides. A substantially circular interposed member 21 provided with a portion 22 is formed, and arcuate ribs 23 provided on both side surfaces thereof at a scale of at least half the circumference of the peripheral portion 28 are shown in FIG. A structure having, for example, a linear rib 24 provided with an imaginary center line 20h extending in the horizontal direction from the center point 20c of the insertion projection 22 as one upper side.

Starting from the lower intersection point of the virtual vertical line 20P of the interposed body 21 and the peripheral portion 28 shown in FIG. 5, at least one-half of the circumference 28 along the direction of the peripheral portion 28, that is, the direction away from the main body frame 1. It is desirable to connect them on a scale.

Next, a method of assembling the first and second joint portions constructed according to the above invention will be described with reference to FIG. Note that this drawing is merely an explanatory diagram, and the positional relationship between the plan view and the bottom view does not always match.

First, in step A, the first joint 10
The linear ribs 14 erected on the intervening body 11 constituting the second joint portion 20 are separated from the arc-shaped ribs 23 erected on the interposed body 21 constituting the second joint portion 20 and the linear ribs 24. 25
Insert

In step B, the first joint 1
The peripheral portion 18 of the supporting body 11 constituting the second joint portion 20 comes into contact with a fitting projection 22 provided at the center of the supported body 21 constituting the second joint portion 20.

Thereafter, in step C, the holding body 11 is expanded by utilizing the elasticity of the synthetic resin, and the fitting projection 22 is fitted into the fitting hole 12.

In this method, no assembly pins or the like are required, so that the assembling process is completed as described above.

Next, the turning action of the joint part constituted by the above mechanism will be described with reference to FIG.

In the drawing, the combined state of the first joint part 10 and the second joint part 20 is expressed on the same plane, and the first joint part 10 with the main body frame 1b having the second joint part is fixed. FIG. 6 illustrates the trajectory of the linear rib 14 (shaded portion) provided in the first joint portion when the main body frame 1a having the following is rotated. In a stage D, the main body frames 1a and 1b are stored in a folded state. Step F shows a state of use which has been developed substantially horizontally, and step E shows a process of changing to each state.

In step D, the linear ribs 14 and 24
Are located on the left and right sides of the center point with the virtual horizontal lines 10h (20h) starting from the center point 10c (20c) of each joint as upper and lower sides as described above.

At step E, when the main frame 1a is to be unfolded, the linear ribs 14
Rotate in conjunction with each other, and move inside the arc-shaped rib 23 provided continuously with the second joint portion.

At the stage F when the main frames 1a and 1b are substantially horizontal, the linear ribs 14 and 24 are arranged in parallel with the virtual horizontal line 10h (20h) interposed therebetween.

At this stage F, the first joint 10
Of the linear rib 2 of the second joint portion 20
4 acts as a stopper and does not rotate beyond the substantially horizontal state of the body frame.

That is, there is no need to provide a contact wall for maintaining the body frame in a substantially horizontal state above the joint portion, and the shape of the contact wall can be freely changed so as not to pinch a finger or the like in the deployed state. .

[0034]

As described above, the joint mechanism of the folding clothes dryer according to the present invention does not require connecting pins at the time of assembling, and thus has an effect of reducing molding and manufacturing costs.

Further, it is not necessary to provide a contact wall for maintaining the main body frame in a substantially horizontal state at the upper portion of the joint portion, so that the danger of pinching a finger or the like during use can be reliably avoided, and at the same time, the upper portion of the joint portion can be prevented. It is possible to apply various designs that do not stick to the wall shape with the gist that does not pinch a finger or the like.

The arc-shaped ribs provided at least one-half of the peripheral edge portion of the clamped member constituting the second joint portion conceal the linear ribs and the like when the main body frame 1 is folded and stored. This has the effect of preventing the appearance of the part from being impaired and preventing foreign substances and the like from entering the gap.

It is to be noted that the arc-shaped rib 2 having at least one-half circumference of the peripheral portion erected on the interposed body constituting the second joint portion
The gap between the linear ribs 3 and the linear ribs 24 is a linear rib 1
4, the linear ribs 14 erected on the interposition body constituting the first joint part at the time of assembling the joint part do not need to cross over the height of the arc-shaped rib 23, and It does not place an excessive burden on the expansion utilizing the elasticity of the cable.
