Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a belt-like cloth tensioning device and a tensioning tool for keeping a belt-like cloth on which an entrance of a store, a shop name or a commercial phrase, etc., always under tension.

[0002]

2. Description of the Related Art Conventionally, banners or other belt-shaped cloths with names or advertisements are pulled at both ends to be tied up, or attached to long rods, rods, etc., like a tomb, or edge plates at both ends. I'm pulling with a string.

[0003] At the entrance of the store, the name of the store or the advertisement is written on a wooden board or a metal plate.

[0004]

The above-mentioned conventional curtains, swords, etc. are difficult to tension even if they are strongly pulled at both ends or side edges, and are usually bent by wind or the like. Then there was a problem such as not returning to the original. Therefore, wooden boards and metal plates are often used at the entrances of shops and the like, which is one reason why easy cloths for printing are not used. In the above, when using a band-shaped cloth,
Even if it is taut at the time of installation, there is a problem that not only is it slack and the appearance is impaired, but also written characters are hard to see after a while.

[0005]

The present invention has solved the above-mentioned conventional problems by constantly applying a tensile force to both ends of a belt-like cloth toward the outside.

That is, the present invention is a belt-like cloth tensioning device characterized in that tension force urging means is attached to both ends of the belt-like cloth, and the tension force urging means is attached to a fixture.
Further, the pulling force urging means is such that one end is fixed to a fixture with a belt-like cloth and the other part is formed with a roll spring, and the roll spring has a spring case with a mounting plate provided with a housing latching means. The accommodating latching means is one in which a roll spring insertion groove is provided in a side wall of a cylinder capable of accommodating the roll spring.

Next, in the invention of the tensioning tool, a rod body which can be inserted into a mounting cylinder portion provided at an end portion of the band-shaped cloth and a supporting rod to which the outer end of the roll spring is fixed are fixed in parallel, and the roll spring is fixed. A belt-shaped cloth tensioning tool housed in a spring case with fixing means, wherein the outer end of the roll spring is inserted into a groove provided in a side wall of the spring case.

In the above invention, the roll spring is
Since it is always urged to the winding side (force to pull the belt-like cloth in the longitudinal direction), the belt-like cloth is always pulled in a direction perpendicular to the left and right edges of the belt-like cloth, so it may temporarily sag due to wind or the like. Even if there is, since it is automatically pulled,
There is no risk of sagging when used for many years. Therefore, since the present invention can be used for all narrow band-shaped cloths, the invention can be used for banners, various kinds of band-shaped cloths, creases, etc., and can be kept in a tensioned state at all times.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION According to the present invention, one end of a coil spring that constantly applies a tensile force in its longitudinal direction is attached to both ends of a strip-shaped cloth, and the coil spring is housed in a spring case with fixing means. The cloth is always supported by tensile force.

Further, since the tensioning tool fixes the strip-shaped cloth fixture and the coil spring fixture in parallel, and the coil spring is detachably accommodated in the accommodating case, the tension force is always maintained.

[0011]

EXAMPLE Small-diameter mounting tubular portions 2 and 2 are provided at both ends of a belt-shaped fabric 1 made of a woven fabric or a synthetic resin sheet, and the tubular portions 2 and 2 are fitted to the rods 3 and 3. , The rods 3 and 3 are fixed in parallel to the supporting rods 4 and 4. An end portion 5a of a roll spring 5 is fixed to the supporting rods 4 and 4 by tacking, and a roll portion 5b of the roll spring 5 is accommodated in a spring case 6. Long groove 7 provided on the side wall of the spring case 6
The roll spring is inserted into the spring, and a fixing plate 9 for fixing to the building or the wall 8 is fixed to the end of the spring case 6 to form a pulling tool 10 (FIG. 4). .

In order to accommodate the roll spring 5 in the spring case 6, the roll spring 5 is automatically moved by extending the roll portion 5b of the roll spring 5 as shown by a chain line a in the figure and inserting it into the long groove 7 as it is. Since it is rolled into a roll, it does not affect the bias.

In the above embodiment, since the roll spring is always biased toward the winding side, the belt-like cloth is pulled in the directions of arrows 11 and 12 in FIG. Therefore, even if the band-shaped cloth sags temporarily due to wind force, etc., it is automatically pulled and always kept taut.

[0014]

According to the present invention, since both ends of the strip-shaped cloth are always pulled in the longitudinal direction by the roll springs, the pulling state can be maintained even if an external force is applied. Therefore, there is an effect that it is not necessary to tie it back in the pulling direction from time to time, and it is possible to always maintain the correct posture and correctly display the drawn characters and the like.
