It is the perspective view which abbreviate | omitted partially which shows the use condition of the rope fastener which concerns on one Example of this invention (Example 1). It is a front view of the fastener main body in FIG. 4 is a cross-sectional view taken along the line A-A 'of FIG. FIG. 5 is a sectional view taken along line B-B ′ of FIG. 3. It is explanatory drawing of the modification of the fastener main body of FIG. It is explanatory drawing which shows the use condition of the other modification of the fastener main body of FIG.

  Hereinafter, the best mode of the present invention will be described based on examples.

An embodiment of the present invention will be described with reference to FIGS. 2 is a partially omitted perspective view showing the state of use of the rope fastener according to the present invention, FIG. 3 is a front view of the fastener body in FIG. 2, and FIG. 4 is taken along the line AA ′ of FIG. FIG. 5 is a cross-sectional view taken along the line BB ′ of FIG.
In FIG. 2 to FIG. 5, 1 is one of the structures of a temporary scaffold, a building frame member standing up and down, and 2 and 3 are protective sheets adjacent to the left and right across the building frame member 1. The right edge 7 of the protective sheet 2 and the left edge 8 of the protective sheet 3 are disposed along both sides of the building frame member 1.

The protective sheets 2 and 3 are fixed to the building frame member 1 by elastic rubber ropes 10 and rope fasteners 20. That is, the rubber rope 10 is wound around the eyelet 4, the building frame member 1, and the eyelet 5 in a ring shape with the eyelets 4 and 5 of the protective sheets 2 and 3 and the building frame member 1 being attached to the rope, and both ends 10 a of the rubber rope 10. 10b is attached to the rope fastener 20 and fixed. The rope fastener 20 has a substantially rectangular plate shape and includes a wooden fastener body (a universal bracket) 21.
As shown in FIG. 3, the fastener body 21 includes four first to fourth rope through holes 22 to 25 that are drilled through the front and back surfaces so as to form the end points of a rectangular diagonal line.

  The first to fourth rope passage holes 22 to 25 are formed by inserting one end portion 10a of the rubber rope 10 into the first and second rope passage holes 22 and 23 and connecting the other end portion 10b to the other end portion 10b. When inserted through the third and fourth rope through holes 24, 25, the rubber rope 10c between the first and second rope through holes 22, 23 of the end 10a, and the third and second of the end 10b The rubber ropes 10d in the portion between the four rope passage holes 24, 25 are arranged so as to overlap each other.

  In this embodiment, the hole diameters c of the first to fourth rope through holes 22 to 25 are all the same, and the hole lengths p are all the same. If the outer diameter of the rubber rope 10 is C, c is formed slightly larger than C, and p is formed to have a length equal to or longer than C. As a result, when the rubber rope 20 is individually pushed into the first to fourth rope through holes 22 to 25 from the tip, the rubber rope 20 can be easily inserted while sliding the outer surface of the rubber rope 20 against the hole wall. Here, as an example, it is assumed that the outer diameter C of the rubber rope 20 is 6 mm, c is 6.5 mm, and p is 8 mm (p may be shorter than C and about 3 mm).

Next, the usage method of the rope fastener 20 comprised as mentioned above is demonstrated.
A fastener body 21 and one rubber rope 20 are prepared in advance.
When it is desired to fix the right edge 7 of the protective sheet 2 shown in FIG. 1 and the left edge 8 of the protective sheet 3 to the building frame member 1 using the rubber rope 10, the rubber rope 10 is attached to the eyelet 4 of the protective sheet 2 and the building frame member 1. The protective sheet 3 is wound around the eyelet 5 in a ring shape, and one end 10a of both ends of the rubber rope 10 is connected from the front end side to the first rope through hole 22 of the fastener body 21 from the back surface 21b side. It is inserted into the 21a side, and further inserted into the second rope through hole 23 from the front surface 21a side to the back surface 21b side, and the tip is pulled out of the fastener body 21. Further, while pulling the other end portion 10 b of the rubber rope 10, the rubber rope 10 is inserted from the front end side into the third rope passage hole 24 of the fastener body 21 from the back surface 21 b side to the front surface 21 a side, and further the fourth rope passage. The hole 25 is inserted from the front surface 21 a side to the back surface 21 b side, and the tip is pulled out of the fastener body 21. Between the first and second rope through holes 22 and 23 at one end 10a of the rubber rope 10, and between the third and fourth rope through holes 24 and 25 at the other end 10b. The rubber ropes 10d of the part are overlapped and intersected.
Thereby, both ends 10a and 10b of the rubber rope 10 are fixed at one place, and the protective sheets 2 and 3 are supported by the building frame member 1.

Here, when the protective sheets 2 and 3 are blown by the wind and are about to be detached from the building frame member 1, the first rope through hole 22 of the fastener body 21, the eyelet 4, the eyelet 5, A large tension is generated in the ring-shaped portion 10 e that reaches the third rope passage hole 24, and both end portions 10 a and 10 b are about to come off the fastener body 21. However, when the rubber rope 10d in the portion between the third and fourth rope passage holes 24 and 25 is about to come out from the third rope passage hole 24, the space between the first and second rope passage holes 22 and 23 is reduced. Is strongly pressed from above (see arrow C in FIG. 4 and FIG. 5), a large friction is generated between the rubber ropes 10d and 10c, between 1c and the surface 21a, and the rubber rope 10d is third. , And the rubber rope 10 c is also prevented from coming out of the first rope passage hole 22.
Further, the outer surface of the rubber rope 10 is difficult to move in the first and third rope through holes 22 and 24 due to sliding contact with the hole wall, and the rubber rope 10 is in a state where a large tension is applied at the hole ports 26 and 27. At about 90 degrees (see FIGS. 4 and 5). At this time, since the rubber rope 10 is pressed against the hole openings 26 and 27 with a strong force to generate a large frictional force, the rubber rope 10 does not have a force to move in the hole axial direction of the first and third rope through holes 22 and 24. This hardly occurs, and this also prevents the rubber rope 10d from coming out of the third rope through hole 24, and the rubber rope 10c is also prevented from coming out from the first rope through hole 22.
Thereby, both ends 10a and 10b of the rubber rope 10 are securely fixed to the fastener body 21.

  When the ring-shaped portion 10e of the rubber rope 10 is loose and it is desired to re-tighten the pin, the tip portion of the rubber rope 10 protruding from the fourth rope passage hole 25 of the fastener body 21 to the back surface 21b side is passed through the fourth rope passage. Push along the hole axis of the hole 25 toward the surface 21a of the fastener body 21 and pull it out. Then, the end portion 10 b of the rubber rope 10 that has been pulled out is pulled along the hole axis of the third rope passage hole 24 toward the surface 21 a of the fastener body 21 to re-tension the ring-shaped portion 10 e of the rubber rope 10. What is necessary is just to pile up on the rubber rope 10c, pulling the end portion 10b, and to insert into the fourth rope through hole 25.

  On the other hand, when the ring-shaped part 10e of the rubber rope 10 is too tight and you want to loosen it a little, the tip part of the rubber rope 10 that protrudes from the fourth rope through hole 25 of the fastener body 21 to the back surface 31b side is 4 is pushed toward the surface 21a side of the fastener body 2 along the hole axis of the four rope through holes 25 and pulled out. Then, the end portion 10b of the rubber rope 10 that has been pulled out is pushed in the direction of the back surface 21b of the fastener body 21 along the hole axis of the third rope passage hole 24, and the tension of the annular portion 10e is slightly relaxed. What is necessary is just to insert the edge part 10b in the 4th rope penetration hole 25. FIG.

  Further, when it is desired to remove the rubber rope 10 from the eyelets 4 and 5 of the protective sheets 2 and 3, the tip portion of the rubber rope 10 protruding from the fourth rope through hole 25 of the fastener body 21 to the back surface 10 b side is used as the fourth. It is pushed out along the hole axis of the rope passage hole 25 toward the surface 21 a of the fastener body 21 and pulled out. Furthermore, the end portion 10b of the rubber rope 10 may be pushed and removed along the hole axis of the third rope through hole 24 toward the back surface 31b of the fastener body 21 and the end portion 10b may be removed from the fastener body 21.

According to this embodiment, when the protection sheets 2 and 3 are attached to the building frame member 1 using the rubber rope 10, the ring 4 is wound around the eyelet 4 of the protection sheet 2, the building frame member 1 and the eyelet 5 of the protection sheet 3. Of the two ends of the rubber rope 10, one end 10 a is inserted from the back surface 21 b of the fastener body 21 to the front surface 21 a through the first rope passage hole 22 and further from the front surface 21 a to the back surface 21 b. 23, the tip portion is pulled out of the fastener body 21, and the other end portion 10b is pulled through the third rope passage hole 24 from the back surface 21b of the fastener body 21 to the front surface 21a. The front end portion of the fastener main body 21 is inserted into the fourth rope through hole 25 from the front surface 21a to the back surface 21b while crossing over the rubber rope 10c between the second rope through holes 22 and 23. By pulling out the parts, simplifies the ends of the rubber rope 10 can be fixed in one place.
When the protective sheets 2 and 3 are blown by the wind and try to come off from the building frame member 1, the first rope passage hole 22 of the fastener body 21, the eyelet 4, the eyelet 5, and the third rope passage in the rubber rope 10. A large tension is generated in the ring-shaped portion 10 e reaching the hole 24, and both end portions 10 a and 10 b are about to come off from the fastener main body 21. However, when the rubber rope 10d in the portion between the third and fourth rope passage holes 24 and 25 is about to come out from the third rope passage hole 24, the space between the first and second rope passage holes 22 and 23 is reduced. The rubber rope 10c is strongly pressed from above, so that large friction is generated between the rubber ropes 10d and 10c, between 1c and the surface 21a, and the rubber rope 10d is prevented from coming out of the third rope through hole 24. The rubber rope 10c is also prevented from coming out of the first rope through hole 22.
Further, the outer surface of the rubber rope 10 is difficult to move in the first and third rope through holes 22 and 24 due to sliding contact with the hole wall, and the rubber rope 10 is in a state where a large tension is applied at the hole ports 26 and 27. At about 90 degrees (see FIGS. 4 and 5). At this time, since the rubber rope 10 is pressed against the hole openings 26 and 27 with a strong force to generate a large frictional force, the rubber rope 10 does not have a force to move in the hole axial direction of the first and third rope through holes 22 and 24. This hardly occurs, and this also prevents the rubber rope 10d from coming out of the third rope through hole 24, and the rubber rope 10c is also prevented from coming out from the first rope through hole 22.
Thereby, both ends 10a and 10b of the rubber rope 10 are securely fixed to the fastener body 21.

When the ring-shaped portion 10e of the rubber rope 10 is loose and it is desired to re-tighten the pin, the tip portion of the rubber rope 10 protruding from the fourth rope passage hole 25 of the fastener body 21 to the back surface 21b side is passed through the fourth rope passage. Push along the hole axis of the hole 25 toward the surface 21a of the fastener body 21 and pull it out. Then, the end portion 10b of the rubber rope 10 that has been pulled out is pulled along the hole axis of the third rope through hole 24 toward the surface 21a of the fastener main body 21 to re-tension the ring-shaped portion 10e of the rubber rope 10, and the rubber rope again. The ten end portions 10b may be pulled over the rubber rope 10c and inserted into the fourth rope through hole 25.
On the other hand, when the ring-shaped part 10e of the rubber rope 10 is too tight and you want to loosen it a little, the tip part of the rubber rope 10 that protrudes from the fourth rope through hole 25 of the fastener body 21 to the back surface 31b side is 4 is pushed toward the surface 21a side of the fastener body 2 along the hole axis of the four rope through holes 25 and pulled out. Then, the end portion 10b of the rubber rope 10 that has been pulled out is pushed in the direction of the back surface 21b of the fastener body 21 along the hole axis of the third rope passage hole 24, and the tension of the annular portion 10e is slightly relaxed. What is necessary is just to insert the edge part 10b in the 4th rope penetration hole 25. FIG.
Further, when it is desired to remove the rubber rope 10 from the eyelets 4 and 5 of the protective sheets 2 and 3, the tip portion of the rubber rope 10 protruding from the fourth rope through hole 25 of the fastener body 21 to the back surface 10 b side is used as the fourth. It is pushed out along the hole axis of the rope passage hole 25 toward the surface 21 a of the fastener body 21 and pulled out. Furthermore, the end portion 10 b of the rubber rope 10 may be pushed and removed along the hole axis of the third rope passage hole 24 toward the back surface 21 b of the fastener body 21, and the end portion 10 b may be removed from the fastener body 21.
Thus, according to the rope fastener 20 of the present embodiment, the tension of the rubber rope 10 can be adjusted, and the rubber rope 10 can be easily attached to and detached from the rope attachment target or the fastener body 21.

  As a modification of the above-described embodiment, as shown in FIG. 5, slits 28, 29 are provided between the second and fourth rope through holes 23, 25 of the fastener body 21A and the left and right edges of the fastener body 21A.
