 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

FIGS. 1 and 2 show a first embodiment of the present invention. Reference numeral 1 denotes a base portion on which the wire ropes 8 are placed, which is made of stainless steel or steel. A mounting portion 2 for the wire ropes 8 is provided in the base portion 1 in the longitudinal direction, and projections 3 and through holes 4 are provided on both sides in the longitudinal direction of the mounting portion 2. The protrusions 3 are slightly wider than the diameter of the wire ropes 8 and are provided in a pair of left and right in the longitudinal direction of the mounting portion 2 in three or more sets. Further, a plurality of pairs of through holes 4 are provided vertically between the protrusions 3 in a pair along the longitudinal direction of the mounting portion 2. Reference numeral 5 is a U-shaped rod provided with a male screw 5A at its tip. Reference numeral 6 denotes a nut screwed with a male screw 5A provided at the tip of the U-shaped rod 5. Reference numeral 7 is a slip stopper formed on the surface of the mounting portion 2 described above. The slip stopper 7 is formed in a convex shape corresponding to the groove on the surface of the wire ropes 8.

Next, the operation of the above configuration will be described.

Two wire ropes 8 are bundled and held by one hand, and the other hand is used to place the wire ropes 8 on the mounting portion 2 provided in the longitudinal direction of the base portion 1. Then, change the base part 1 together with the wire ropes 8. At this time, the pair of left and right through holes 4 at the end vertically provided on the base 1 is held so as to be exposed. Then, both ends of the U-shaped rod 5 are inserted so as to sandwich the wire ropes 8 and the nut 6 is screwed from the lower surface side of the base portion 1. Further, similarly, the U-shaped rod 5 is similarly inserted into the other pair of left and right through holes 4, the nut 6 is screwed, and the wire ropes 8 are tightened. In this case, since the convex anti-slip 7 is formed on the surface of the mounting portion 2, the groove formed on the surface of the wire ropes 8 engages with the anti-slip 7, and the U-shaped rod 5 is attached to the nut 6 as the base. It is tightened strongly by being screwed on the part 1.

Therefore, since the through holes 4 and the protrusions 3 are provided on both sides of the base portion 1 in the longitudinal direction, the wire ropes 8 are surely placed on the placing portion 2 by using the protrusions 3 as guides, and the U-shape. When inserting the rod 5 into the through hole 4, the base portion 1 can be held together with the wire ropes 8 with one hand so as to expose the pair of left and right through holes 4 provided at the end of the base portion 1. The work of inserting the U-shaped rod 5 into the through hole 4 can be easily performed. Further, the U-shaped rod 5 can be held with one hand by re-holding the hand holding the wire ropes 8 and the base portion 1, so that the male screw provided at the tip of the U-shaped rod 5 can be held. The operation of screwing the nut 6 onto the child 5A can be easily performed. Then, when inserting the other U-shaped rod 5 into the other through hole 4, the wire ropes 8 are already tightened by the base portion 1 and the U-shaped rod 5, so that the base portion 1 is not held and quickly. The U-shaped rod 5 can be inserted into the through hole 4 and the nut 6 can be screwed. Further, the convex anti-slip 7 formed on the surface of the mounting portion 2 and the groove formed on the surface of the wire ropes 8 are engaged with each other, and a plurality of U-shaped rods 5 are screwed to the base portion 1. Therefore, the wire ropes 8 are strongly tightened.

As described above, the base portion is provided with a mounting portion for wire ropes and a pair of left and right protrusions having a width slightly larger than the diameter of the wire ropes in the longitudinal direction of the mounting portion. Since a plurality of pairs of left and right through-holes are vertically provided between the protrusions along the longitudinal direction of the mounting portion, the wire ropes are exposed while the end of the through-hole is exposed when tightening the wire ropes. Since the base part can be held with one hand, the U-shaped rod can be easily inserted into the through hole. Furthermore, by re-holding the hands holding the wire ropes and the base part, the wire ropes, the base part and the U-shaped rod can be held with one hand, and the nuts can be screwed together without worrying about the U-shaped rod falling. be able to. Also, since a convex anti-slip is formed on the surface of the mounting part, the groove on the surface of the wire rope and the convex anti-slip are engaged, and there is no deviation between the wire rope and the base part. The ropes 8 can be tightened strongly.

It should be noted that the present invention is not limited to the above-described embodiment. For example, a base portion having no protrusions, a wire rope mounting portion having a substantially U-shaped groove, or a sliding portion is formed. Various modifications are possible, such as providing a stopper projection on the U-shaped rod side.
