[Embodiment of the invention]

 Hereinafter, a fastener according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a front view of the fastener according to the first embodiment of the present invention, FIG. 2 is an explanatory view for explaining an example of use of the fastener according to the first embodiment of the present invention, and FIG. FIG. 5 is a front view of the fastener according to the second embodiment of the present invention.

First, a fastener according to a first embodiment of the present invention will be described with reference to FIG. The fastening device 1 includes a substantially rectangular plate body 2 obtained by resin molding and an attachment cord D to which a starting end is fixed. One end side (upper side in the drawing) of the plate body 2 includes: A fixing portion 3 for tying the start end of the attachment string D together and fixing it, and the attachment string D tied and fixed to the fixing portion 3 are provided between each eyelet or the like of an attached body such as an awning. An insertion portion 4 is provided for penetrating the plate 1 from one surface side to the other surface side after the insertion. The insertion portion 4 is provided in the vicinity of the fixing portion 3 so that the attachment string D starting from the fixing portion 3 is inserted between the eyelets a and b of the awnings A and B, and then inserted into the insertion portion 4. By returning, almost a loop can be formed. At the other end (the lower side in the drawing) of the plate 2, an attachment cord is formed at a position opposite to the insertion portion 4 provided in the vicinity of the fixing portion 3 and penetrates the insertion portion 4. A main slit 5 is provided for fixing by sandwiching and locking D 1. In addition, the resin material of the substantially rectangular plate body 2 constituting the fastening device 1 is not necessarily limited, but it is preferable that the resin material is made of a synthetic resin material having particularly excellent impact resistance.

[0008] The fixing portion 3 is configured such that the starting end portion of the attaching cord D fixedly attached thereto does not easily come off. The insertion portion 4 has a sufficient area for inserting the attachment cord D through the attached body, and has, for example, an O-shaped inner shape when viewed from the front.

The fixing portion 3, the insertion portion 4, and the main slit 5 are desirably set so as to be substantially on the same line in the plate 2. With this setting, the pigeons of the awning are inserted after they are tied to the fixing portion 3, and the attachment string that has penetrated the insertion portion 4 is interposed and locked by the main slit 5. In this case, a rotation moment hardly acts on the lower end of the plate body 2, the lower end of the plate body 2 is less likely to be inclined and lifted, and the attachment cord can be hardly loosened.

In the vicinity of the entrance of the main slit 5, a V-cut 5 a is provided so that a mounting cord can be easily inserted into the main slit 5. The main slit 5 is desirably configured so as to be narrower toward the back, so that the attachment string sandwiched between the slits is not easily detached.

Further, in the middle part between the insertion portion 4 and the main slit 5, sub slits 6, 6 cut in opposite directions to the cutting direction of the main slit 5 are provided at both ends thereof, The attachment string fixed by being sandwiched and locked by the main slit 5 is further sandwiched and locked by the sub-slit 6 so that the attachment string can be more firmly and securely fixed. The sub-slit 6 is also V-cut 6a near the entrance, so that the attachment cord can be easily inserted into the sub-slit 6. It is to be noted that the auxiliary slits 6, 6 can be more securely fixed to the main slit 5 or the sub slits 6, 6 by making the slit widths slightly different from each other.

In the above description, when the plate body 2 is formed, the attachment cord D may be integrally fixed to the fixing portion 3 or may be fixed in advance with an adhesive. In this case, The work of tying the fixing part 3 and the mounting cord D can be omitted. The dimensions of the substantially rectangular plate 2 constituting the fastener 1 are, for example, 10 cm long × 3 cm wide × 0.5 cm thick, and the length of each of the main slit 5 and the sub slit 6 is 2 cm. And the diameter of the insertion portion 4 is about 1 cm, but it is needless to say that these dimensions can be appropriately changed in consideration of the dimensions of the mounting cord and other conditions.

Next, an example of use of the fastener according to the above configuration will be described with reference to FIG. First, the starting end of the attachment string D is tightly tied to the fixing portion 3 of the plate 2. Then, one end of the attachment string D is inserted from the dovetail a of the awning A to the back side, and dive under the back surface of the vertically-standing steel pipe C from the dovetail b on the back side of the awning B, and Take it out to the front side and take out the above-mentioned attachment cord D. Subsequently, the attachment cord D is penetrated from one surface side to the other surface side in the insertion portion 4 while being pulled in the plate body 2 direction. Then, the string is inserted into the main slit 5 from the V cut 5a portion of the main slit 5 while strongly pulling the penetrating attachment string D. By operating in this manner, the attachment string D is clamped and locked in the main slit 5 in a tensioned state, and the awning A and the awning B are attached in a tensioned state. Further, the attachment string D fixed by being sandwiched and locked in the main slit 5 is further inserted into the sub-slit 6 from the V-cut 6a portion of the sub-slit 6 and strongly pulled in the main slit 5 side. The attachment string D is more securely fixed. In this manner, the attachment cord D for attaching the awning A and the awning B in a tensioned state forms a substantially closed loop between the fixing portion 3 and the insertion portion 4 provided in the vicinity thereof, and eliminates the generation of a rotational moment. doing. When the attachment string D enters the insertion section 4 from the eyelet b and is fixed by being sandwiched and locked in the main slit 5, the attachment string D and the insertion section 4 for penetrating the attachment string D are fixed. Means that a frictional force is generated at the portions F1 and F2, and the frictional force generated at these insertion portions 4 is combined with the pinching and locking function in the main slit 5 and the sub-slit 6 so that the fastening device 1 Functioning.

On the other hand, in the operation of removing the attachment string D, the procedure opposite to that described above is performed, that is, the attachment string D that has entered the interior of the main slit 5 (and, in some cases, the inside of the sub-slit 6) is removed. Pulling out in the V-cut 5a direction (after pulling out the attachment cord D, which may enter the inner side of the sub-slit 6 in the V-cut 6a direction in some cases), releases the pinching lock. As a result, the attachment string D inserted through the eyelet a of the awning A and the eyelet b of the awning B is in a relaxed state, and then only the pulling end of the attachment string D is pulled. The above-mentioned attachment cord D inserted into each of the eyelets a and b can be removed almost instantaneously in a one-touch manner.

According to the above configuration, the attachment string D is inserted into the eye a of the awning A, and is sunk under the steel pipe C between the awning A and the awning B to be inserted through the eye b of the awning B. After passing through the insertion portion 4, the tents A and B are merely fastened and fastened by the main slits 5 (in some cases, the main slits 5 and the sub-slits 6). On the other hand, there is no need to strongly tie or tie the attachment string D so that it is difficult to unravel, and the work of attaching the awning A and the awning B can be performed easily, quickly, and reliably. On the other hand, even when the attachment cord D is to be removed, simply and quickly releasing the pinch lock of the plate body 1 in the main slit 5 (in some cases, the main slit 5 and the sub-slit 6) can be performed simply and quickly. Work efficiency is very good because it can be done reliably. Therefore, there is the convenience that anyone, even a non-skilled worker, can immediately perform the installation work. In addition, the attachment string D can be removed without cutting, and can be reused by being recovered while being fixed to the plate, thereby saving resources.

In the plate 1, the fixing of the attachment string D by pinching and locking can be sufficiently performed only by the main slit 5. However, not only the main slit 5 but also the sub-slit 6 can be pinched and locked. By doing so, even if the fixing of the attachment string in the main slit 5 is loosened, the attachment string D is securely sandwiched and locked by the sub-slit 6, so that there is no possibility that the attachment string D is loosened. In addition, it will exhibit its perfect function as the intended fastener.

If a V-cut is made in the vicinity of the entrance of the main slit 5 or the sub-slit 6 as necessary, the attachment string D can be easily inserted into the main slit 5 or the sub-slit 6, and the workability is extremely high. There is an advantage of improving.

A fastening device according to a second embodiment of the present invention will be described with reference to FIG. The fastening device according to this embodiment is slightly different from the fastening device according to the first embodiment only in the configuration of the insertion portion 4, and the differences will be described. The fastening device 1 in the embodiment has one end of the insertion portion 4 opened. Specifically, a slit 4a is formed by making a cut in one end of the insertion portion 4. The slit 4a is not limited to the case where it is provided between the upper portion of the insertion portion 4 and the fixed portion 3 as shown in the figure, and a slit is formed in a side end of the plate body 2 so as to communicate with the insertion portion 4. It may be. However, it goes without saying that the width of the slit 4a is set so that the starting end of the attachment cord D does not easily come off. The mode of use and its effects are basically the same as those according to the first embodiment, but as described above, the slit 4a is formed in the insertion portion 4 so that the starting end of the mounting cord D is fixed. After being tied and fixed to the portion 3, the tent is inserted through the eyelets of the awning and folded back, and when the tent is passed through the insertion portion 4 again, the attachment cord D is inserted from the slit 4 a. Therefore, there is an advantage that the work can be easily passed through the insertion portion 4, and the subsequent work can be performed more quickly. It is preferable that the insertion portion 4 has a shape such that the starting end of the attachment string D fixed to the fixing portion 3 does not easily come off.

As described above, according to the fastener according to the first and second embodiments of the present invention, a covering such as an awning stretched around the outer periphery of a building under construction such as a building, a house, or a bridge. Not only can it be used to attach the attachment bodies to each other in a tensioned state with an attachment string, but also the versatility that it can be used to widely attach the covering covers in the packing field and material storage area with the attachment string. It has a wide range of use.
