DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a futon pinch provided with a mechanism for suppressing wind tilt.

[0002]

2. Description of the Related Art The effect of the wind when drying a futon has become more pronounced as a tidal wind with the rise of houses in recent years, and the futon has been easily turned upside-down with a conventional futon sandwich, and has been liable to be bounced off together with the futon. .

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a futon pinch which suppresses the futon tilt even when wind blows.

[0004]

According to the present invention, as a means for restraining the futon from flapping, a cylindrical, flexible telescopic arm having an arc-shaped rotary support arm 7a and a support arm 8a with respect to both arms 1a and 1b. The stop rods 6a and 6b are provided so as to be able to be tightened at an arbitrary angle by fastening screws 9a, 9b, 9c and 9d.

[0005] Further, the arms 1a, 1b and the tilting stop bars 6a, 6
As means for further increasing the degree of tightening of b, a washer 10a is provided on the outer surface of the arc-shaped rotary support arm 7a so as to cut in a serpentine direction in the outer direction, and is provided with a concave and convex engaging with this.
10b can be inserted between the screws 9a and 9b.

On the other hand, as means for further increasing the simplicity of the mechanism, the arms 1a, 1b and the outer cylinders of the tilt stopper bars 6a, 6b can be removed by omitting the angle adjusting mechanism of the tilt stopper bars 6a, 6b.
It can also be formed integrally .

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIG. Cylindrical telescopic tilt stoppers 6a, 6
b, an arc-shaped rotation support arm 7a and a support arm 8a are formed. The arc-shaped rotary support arm 7a has an arc-shaped hole for penetrating the screws 9a and 9b, and as the center of the arc, the support arm 8a has a circular hole for penetrating the screws 9c and 9d. Provide. On the other hand, the screws 1a, 9b, 9c, 9
Cut a screw groove for d. In use, the pivoting rods 6a and 6b are stretched to an arbitrary length, and the lower end is opened at an angle to open the arm 1 with the setscrews 9a, 9b, 9c and 9d.
a, 1b are tightened slightly loosely. Next, the holding portion 2a,
After holding the futon by 2b, the tilting rod is adjusted to an angle such that the lower end appropriately presses the lower end of the futon, and tightened securely with the fastening screws 9a, 9b, 9c, 9d.

A second embodiment will be described with reference to FIG. Serrated irregularities are provided on the outer surface of the arc-shaped rotation support arm 7a so as to be cut in the direction of the back of the arm. In addition, washers 10a and 10b are formed in which concave and convex portions are meshed with the washers. In use, the arc-shaped rotary support arm 7a and the screw 9
The washer 10a, 10b is inserted between a, 9b so that the unevenness of the washer engages with the rotation support arm.

A third embodiment will be described with reference to FIGS. Arms 1a of FIG. 1, the retractable at 1b and cylindrical
By integrally forming the outer cylinders of the pivoting rods 6a and 6b,
3, the telescoping integrated tilting stop rods 6 a ′ and 6 shown in FIG.
b ' .

It should be noted that all claims of the present invention can be applied to any mechanism such as a tension coil spring, a torsion coil spring, or the like, as a tensile force between both arms.

[0011]

According to the above configuration, the present invention provides:

According to the first aspect of the present invention, (1) the lower end portion of the futon can be appropriately pressed according to the size and thickness of the futon with the anti-tilt bar so that the wind can be suppressed. it can. (B) During storage, the size can be reduced to the size of a conventional product.

(3) When the fastening screws 9a, 9b, 9c, 9d are loosely fastened, the lower ends of the tilting rods 6a, 6b are moved from the open angle position to the closed angle position. The slide can be adjusted stepwise along the irregularities. (D) When the fastening screws 9a, 9b, 9c, 9d are firmly fastened, the degree of fastening can be made stronger in the opening direction of the lower ends of the tilting stop bars 6a, 6b, thereby suppressing tilting. Power can be increased more.

According to the third aspect of the present invention, the integration of the arm and the stopper bar can simplify the molding of the component (e).

According to all claims, (f) Since each mechanism is symmetrical in both arms, molding of each part can be performed by a single mold. It is possible to exhibit the effect of saying.
