Description

[0001]
BACKGROUND OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a belt-like cloth tensioning device and a tensioning tool intended to keep a belt-like cloth or the like describing a shop name or a promotional phrase in a tension state at all times.
[0002]
[Prior art]
For a traditional banner or other belt-like cloth, the name or promotional text has been drawn and tied at both ends, or attached to a long rod or heel like a heel, or the edge plates at both ends are pulled with a string or the like. Yes.
[0003]
In addition, at the entrance of a store or the like, a store name or an advertisement is written on a wooden board or a metal plate.
[0004]
[Problems to be solved by the invention]
The above-mentioned conventional curtains, scissors, etc. are difficult to stretch even when pulled strongly at both ends or side edges, and are usually bent by the wind, etc. was there. Therefore, wooden boards and metal plates are frequently used at the entrances of shops and the like, which is one of the reasons why easy cloths such as printing are not used. In the above, when a belt-like cloth is used, there is a problem that, even if it is tensioned at the time of installation, not only the slack and appearance are impaired after a while, but also the written characters are difficult to see.
[0005]
[Means for Solving the Problems]
The present invention solves the above-mentioned conventional problems by always applying a tensile force to both ends of the belt-like cloth toward the outside.
[0006]
That is, in the present invention, the cylindrical portions 2 and 2 are provided at both ends of the belt-like cloth, the cylindrical portions 2 and 2 are fitted into the casings 3 and 3, and one ends of the casings 3 and 3 are connected to the roll spring 5. The inner end side of the roll spring 5 is housed in a roll shape in the spring case 6 and is detachably hooked to the spring case 6. strip a cloth stretched device, hooking of being accommodated in a roll into the spring case, the inner end side of the roll spring, a cylindrical spring, characterized in that attaching the securing means to the spring case 6 accommodated into the spring case through insertion groove provided on the case side wall of the one in which a roll-shaped portion of the spring housed in the spring case has detachably by engaging the spring case.
[0007]
Next, the invention of the tension tool includes: a casing that can be fitted with a cylindrical portion provided at an end of the belt-like cloth; and a support that is parallel to the casing. the outer end portion is fixed, the inner end side of the roll spring, through the grooves of the scan pulling casing, is housed into the spring case, b Lumpur shaped portion of the spring entering into the spring casing and a scan pulling casing detachably hooked Rutotomoni a tensioner of the belt-like fabric which is characterized in that a fixing means to the spring case, the fixing means is obtained by a fixing plate provided at an end portion of the roll case .
[0008]
In the above invention, since the roll spring is always urged to the entrainment side (force that pulls the belt-like cloth in the longitudinal direction), the belt-like cloth is always pulled in the direction perpendicular to the left and right edges, Even if it may sag temporarily due to, for example, it is automatically pulled, so there is no risk of sag during long-term use. Accordingly, the present invention can be used for all narrow strips of cloth, so that it can be kept stretched at all times when used for banners, various display strips or bags.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
In this invention, one end of a coil spring that always applies a tensile force in the longitudinal direction is attached to both ends of the belt-like cloth, and the coil spring is accommodated in a spring case with a fixing means, so the belt-like cloth is always supported by a tensile force. Is done.
[0010]
Moreover, since the tension | tensile_strength fixture fixed the strip | belt-shaped cloth fixture and the fixture of a coil spring in parallel, and the coil spring was detachably accommodated in the accommodation case, tensile force is always hold | maintained.
[0011]
【Example】
At both ends of the belt-like cloth 1 made of a woven cloth or a synthetic resin sheet, small-diameter mounting tubular parts 2 and 2 are provided, and the tubular parts 2 and 2 are fitted into the casings 3 and 3, respectively. 3 is fixed to the supports 4 and 4 in parallel. An end 5 a of a roll spring 5 is fastened and fixed to the supports 4 and 4, and the roll portion 5 b of the roll spring 5 is accommodated in a spring case 6. The roll spring is inserted into the long groove 7 provided in the side wall of the spring case 6, and a fixing plate 9 for fixing to the building or the wall 8 is fixed to the end of the spring case 6. The tool 10 is comprised (FIG. 4).
[0012]
In order to accommodate the roll spring 5 in the spring case 6, the roll spring 5 is automatically rolled by extending the roll portion 5b of the roll spring 5 as shown by a chain line in FIG. Because it is caught in the shape, there is no effect on the bias.
[0013]
In the above embodiment, the roll spring is always urged toward the winding side, so that the belt-like cloth is pulled in the directions indicated by arrows 11 and 12 in FIG. Therefore, even if the belt-like cloth temporarily sags due to wind power or the like, it is automatically pulled and always kept taut.
[0014]
【The invention's effect】
The present invention, both ends of the band-shaped cloth so being pulled at all times longitudinally by Russia Lumpur spring force is effective to keep the state and tension pin be added. Where sometimes tension there is no need to re-tied to the direction, keeping always correct attitude, there is a drawn characters, such as may be the display correctly effect.
