FIG. 2 is a bottom view, FIG. 2D is a right side view, and FIG. 2 is an explanatory view for explaining a state in which awnings are attached to each other by the fastener according to the first embodiment of the present invention. FIG. 3 shows a second embodiment of the invention.
FIG. 4 is a front view of a fastener according to a third 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 is formed of a plate 1 obtained by resin molding, and is fixed to one end side (upper part in the drawing) of the plate 1 with a start end of an attachment cord D (see FIG. 2). Tying part 2 and this tying part 2
And an insertion portion 3 for allowing a mounting cord fixed and fixed to each other to be inserted between eyelets and the like of an attached body such as an awning and then penetrating from one side of the plate body 1 to the other side. . The insertion portion 3 is provided near the attachment portion 2. As a result, the attachment string D starting from the attachment portion 2 returns to the insertion portion 3 after passing through the attached body, thereby forming a substantially loop shape. Also, on the other end side (the lower part in the drawing) of the plate body 1,
A main slit 4 is formed at a position opposite to the insertion portion 3 provided in the vicinity of the consolidation portion 2, and is for inserting a mounting cord that penetrates the insertion portion 3. The constituent resin of the plate 1 is not necessarily limited, but a synthetic resin having particularly excellent impact resistance is desirable.

The tying portion 2 is formed in a hook shape, that is, a hook shape having a locking function, so that the starting end of the tying and fixing attachment string is not easily detached. The insertion portion 3 has a sufficient area to allow the attachment cord to penetrate, and has an inner shape formed in a C shape in a front view, for example, as shown in FIG. That is, in the present example, the insertion portion 3 has an opening 3a at one end thereof in order to make it easy for the attachment cord after being inserted between the eyelets of the attached body such as the awning to pass through the insertion portion 3. It is open.

The consolidating part 2, the insertion part 3, and the main slit 4 are desirably set so as to be substantially collinear in the plate 1. By setting in this manner, when each eyelet of the awning is inserted after being tied to the tying part 2, and furthermore, the attachment cord that has penetrated the tying part 3 is fixed by being sandwiched by the main slit 4. In addition, a rotational moment hardly acts on the lower end of the plate 1, the lower end of the plate 1 is less likely to be inclined and lifted, and the attachment string can be made less likely to be loosened.

The vicinity of the entrance of the main slit 4 is V
The cut 4a makes it easy to insert the attachment string into the main slit 4, and the main slit 4 is also narrowed toward the back so that the attachment string fixed by being sandwiched is not easily detached. .

If necessary, a sub-slit 5 is formed in a central portion between the insertion portion 3 and the main slit 4 so as to be formed in a direction opposite to a direction in which the main slit 4 is formed. The attachment string sandwiched and fixed by the main slit 4 can be further sandwiched and fixed. The sub-slit 5 also has a V cut 5a near the entrance.
The end of the attachment string is easily inserted into the sub-slit 5.

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 strongly tied to the tying part 2 of the plate 1. Of course, the attachment string D may be simultaneously and integrally fixed to the molded character of the plate 1.
Then, one end of the attachment string D is inserted from the dovetail a on the front side of the awning A to the back side, and is inserted under the rear face of the steel pipe C vertically erected from the dovetail b on the back side of the awning B. To the front side of the awning B to take out the attachment string D. Subsequently, the attachment cord D is penetrated from one side to the other side into the insertion portion 3 from the opening 3a while being strongly pulled in the direction of the plate 1. Then, the penetrating attachment string D is inserted into the main slit 4 from the V cut 4a of the main slit 4 while being strongly pulled. By operating in this manner, the attachment string D is sandwiched and fixed in the main slit 4 in a tensioned state, and the awning A and the awning B are linked in a tensioned state. Further, if necessary, the attachment cord D inserted and fixed in the main slit 4 is further inserted into the sub slit 5 from the V cut 5a portion of the sub slit 5, and strongly pulled in the direction of the main slit 4 to thereby attach the attachment cord D. D is more securely fixed. In this manner, the attachment string D that connects the awning A and the awning B in a tensioned state forms a loop between the tying portion 2, the eyelets a and b, and the insertion portion 3. Then, after entering into the insertion portion 3 from the eyelet b, when it is inserted and fixed in the main slit 4, as shown in FIG. It is considered that the frictional force generated in these insertion portions 3 is exerting the function of the fastener 1 in combination with the function of pinching and fixing in the main slit 4 and the sub-slit 5.

On the other hand, when removing the attachment string D,
The procedure opposite to the above is performed, that is, the attachment cord D that has penetrated into the interior of the main slit 4 (and in addition to the inside of the sub-slit 5) is pulled out toward the V cut 4a (in some cases, the inside of the sub-slit 5). By pulling out the attachment string D that has entered the back in the direction of the V cut 5a), the pinching and fixing is released. As a result, the attachment string D inserted through the eye a of the awning A and the eye b of the awning B is in a relaxed state, and thereafter the awning A is pulled only by pulling the starting end of the attachment string D.
And the above-mentioned attachment cord D inserted into each eyelet a, b of the tent B
Can be removed almost instantly.

According to the above construction, the attachment string D is inserted through 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 3, the tents A and B are merely fastened and fastened by the main slits 4 (in some cases, the main slits 4 and the sub-slits 5). There is no need to tie or tie the attachment string D so that it is difficult to unravel.
Can be easily and quickly performed. On the other hand, the attachment string D
In the case of removing the plate, it is possible to simply and quickly release the sandwiching and fixing between the main slits 4 (in some cases, the main slit 4 and the sub-slit 5) of the plate body 1 in a one-touch manner. Therefore, there is the convenience that anyone, even a skilled worker, can immediately perform the mounting work. Moreover, since the attachment string D can be removed without cutting, resources can be saved, such as being reused without being wasted.

In the plate body 1, the fixing cord D can be sandwiched and fixed only by the main slit 4. However, if the sub slit 5 is provided in addition to the main slit 4,
Even when the fixing of the mounting string D is loosened and fixed by the main slit 4, the mounting string D is securely inserted and fixed by the sub-slit 5, so that there is no possibility that the mounting string D is loosened. Becomes

When a V-cut is made near the entrance of the main slit 4 or the sub-slit 5, there is an advantage that the attachment cord D can be easily inserted into the main slit 4 or the sub-slit 5, and the workability is greatly improved. is there.

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 3, and thus detailed description thereof is omitted. That is, in the plate 1 according to the embodiment, the inner shape of the insertion portion 3 is configured to be O-shaped when viewed from the front. Its use mode and its effects are basically the same as those according to the first embodiment, but as described above, the inner shape of the insertion portion 3 is formed into an O-shape in a front view, so When the starting end of the cord is tied to the tying part 2 and inserted between the eyelets of the awning and turned back, the inside of the insertion part 3 is penetrated, and the attaching cord that is strongly pulled is clamped in the main slit 4 and fixed. There is an advantage that the work can be performed in a more reliable state, without any risk of slipping out of the insertion portion 3.

Next, a fastener according to a third embodiment of the present invention will be described with reference to FIG. The basic structure of the fastener according to the embodiment is the same as that of the fastener according to the first and second embodiments. The difference is that all unnecessary portions around the bundle portion 12, the insertion portion 13, the main slit 14 and the sub slit 15 are removed, and these bundle portions 12, the insertion portion 13, the main slit 14 and the sub slit 15 are used for reinforcement. The point is that the plate body 11 is configured to have strength by providing the ribs 16. In addition, like the first and second embodiments, the main slit 14 and the sub-slit 15 can be easily inserted with the attachment string.
V cuts 14a and 15a are made near the entrance. Since the use mode and the effect are basically the same as those according to the first and second embodiments, detailed description thereof will be omitted, but particularly in this configuration, it is used at the time of molding. By reducing the amount of resin material, material cost can be reduced, and the weight of the fastener can be reduced.

And the like, wherein the tightening tool is formed of a plate, and the plate includes a binding portion for fixing a starting end of the mounting string, An insertion portion for inserting an attachment string whose start end portion is fixed to the attachment portion between the eyelets and the like of the attached bodies and then penetrating the plate from one side to the other side; Since it has a main slit for sandwiching the attachment cord that penetrated the part, after inserting the attachment cord fixed to the binding part of the plate body between the attached bodies such as each eyelet of the awning, The attachment string can be easily and quickly and reliably sandwiched and fixed by the main slit via the insertion portion. Also, the attachment cord can be easily and quickly removed simply by releasing the main slit from being sandwiched and fixed. Therefore, there is no necessity to tightly tie the attachment cord to the awning so that it is difficult to unravel the awning as in the related art, and there is the convenience that anyone, even a skilled worker, can perform the attachment work. In addition, the attachment cord can be detached without cutting and can be reused, thereby saving resources. According to the fastening device of the second aspect, in addition to the effect of the configuration of the first aspect, the binding portion, the insertion portion, and the main slit are formed substantially on the same line.
When the attachment string passed between the pigeon eyes of adjacent awnings after being tied and fixed to the tying part, penetrated through the insertion part, strongly pulled in the direction of the fastener, and pinched and fixed in the main slit, It is difficult for the rotational moment to act on the lower end of the plate,
There is no danger that the lower end of the plate body will be inclined and lifted, and the attachment cord will not easily be loosened. Thereby, the attachment cord that has been inserted between the adjacent eyelids and the like between the awnings by using the fasteners is maintained in a tensioned state, and a good attachment state can be secured. According to the third aspect of the present invention, in addition to the effect of the configuration of the first aspect, since one end of the insertion portion is open, the attachment cord fixed by being fixed to the attachment portion is inserted. It is easy to insert the cord into the main slit, and it is very easy to perform the subsequent work such as pinching and fixing the attachment cord into the main slit, thereby improving workability as a whole. Further, according to the fastening device of the fourth aspect, in addition to the effect of the configuration according to any one of the first to third aspects, the main slit is formed in a central portion between the consolidating portion and the main slit. Since the sub-slit is formed in a direction opposite to the groove direction, the attachment string sandwiched and fixed by the main slit can be further sandwiched and fixed by the sub-slit. Therefore, even if the pinch fixing in the main slit is loosened, the attachment string is securely pinched and fixed by the sub slit,
The attachment string that connects the awnings to each other in tension is not loosened, and secure attachment can be ensured.
