【Example】

 An embodiment of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 to 8, diagonally crossed lower arms 2 and 2 are crossed inward from both lower end portions of both upper arms 1 and 1 that intersect in a mountain shape, and each crossing point is pinned. 3 ... The upper arms 1 and 1 and the lower arms 2 and 2 are fastened so as to be rotatable. Vertical plates 4 are respectively hung on the lower end portions of the lower arms 2 and 2, and locking pieces 5 and 5 are provided inside the vertical plates 4 and 4 to form a basic structure of a block suspender 15. .

A suspension rod 6a is provided at the intersection of the upper arms 1 and 1 of the block suspension 15, and a suspension rod 6b is provided at an appropriate position on the oblique side of one upper arm 1.

Next, the horizontal portions 7, 7 are provided from the upper side of the vertical plates 4, 4 so as to face inward. As shown in FIGS. 4 and 6, the horizontal portions 7, 7 are provided between the tips of the horizontal portions 7, 7. The vertical plates 4 and 4 are provided with a gap X corresponding to the size for opening and closing in the left and right directions, and vertical members 10 and 10 that prevent vertical movement are fixed to the lower arms 2 and 2. Further, as shown in FIG. 8, both ends of the grasping tool 8 in a plan view, the intersections of which are inserted through the vertical axis 11a and which are vertically supported by the rings 12 and 12, are attached to the horizontal portion 7a. , 7 are fixed to the inner ends.

At this time, as shown in FIG. 7, a pipe body 13 is fixed to both ends of the grasping tool 8, the vertical axis 11b is inserted into the pipe body 13 in an internally fitted state, and the horizontal portion 7 On the lower surface, a stop ring 12 is provided, and on the upper surface of the horizontal portion 7, the connection ring 14 is provided by a stop ring 12 via a connection plate 14. Incidentally, one insertion hole of the connecting plate 14 through which the vertical axis 11b is inserted is formed in an elliptical hole 14a corresponding to a size that the vertical plates 4 and 4 should be opened in the left-right direction as shown in FIGS. It will be done.

Next, a method of suspending the block body 9 using the block suspending tool 15 will be described. First, as shown in FIGS. 9 to 11, when the block body 9 having the concave groove 9a on its side surface is hung in a stacking manner, the block body 9 is hung on the hanging rod 6a at the center of the hanging tool 6 for blocks. The locking piece 5 is guided to the concave groove 9a of the block body 9 while the gripping tool 8 is opened in the left-right direction while locking the hook and the like. At this time, since the connecting plate 14 for connecting the horizontal portions 7 is provided with the elliptical holes 14a corresponding to the size of the vertical plates 4, 4 to be opened in the left-right direction, the maximum opening size of the gripping tool 8 is obtained. Is limited, and the force to open the gripping tool 8 is not required more than necessary. Then, when the rope is wound up at the time when the locking piece 5 is tightened inwardly and the locking piece 5 is fitted into the groove 9a, the vertical force, which is the weight of the block body 9, is lifted by the lever action of the block suspending tool 15.
