The compression coil spring 79a is accommodated in the inner cylinder 78d of the inner case 78, and the torsion coil spring 79b is accommodated between the intermediate cylinder 78b and the inner cylinder 78d of the inner case 78. Further, the adjustment rotor 79c accommodates the compression coil spring 79a, is accommodated in the inner cylinder 78d of the inner case 78, is formed shorter than the inner cylinder 78d, and is rotatable in the circumferential direction with respect to the inner case 78. A cylindrical body 79d slidable in the direction, a large-diameter flange 79e provided integrally with the cylindrical body 79d and positioned on the end surface of the cylindrical body 79d, and the opposite side of the both sides of the flange 79e to the cylindrical body 79d A grooved shaft portion 79f projecting from the center of the flange 79e on the surface, a locking projection 79g having a smaller diameter than the grooved shaft portion 79f projecting from the grooved shaft portion 79f, spaced from the grooved shaft portion 79f, and a flange It consists of the recessed part 79h formed in the outer peripheral surface of 79e.

One end of the torsion coil spring 79b accommodated between the intermediate cylinder 78b and the inner cylinder 78d of the inner case 78 is engaged with the lid 78c of the inner case 78, and the other end of the torsion coil spring 79b is the adjustment rotor 79c. The flange 79e is engaged with the recess 79h (FIG. 16). Further, a through hole 77e is formed in one disc 77c of the outer case 77 so as to rotatably accommodate the grooved shaft portion 79f of the adjusting rotor 79c, and the inner disc 78 is provided in the other disc 77d of the outer case 77. A through hole 77f that rotatably accommodates the shaft portion 78e of the lid 78c is formed, and the inner case 78 rotates relative to the outer case 77 around the shaft portion 79f with the groove and the shaft portion 78e. (FIGS. 15 and 16). In addition, one of the circular plates 77c of the outer case 77 is formed with three locked holes 77g at predetermined intervals on the circumference centering on the through hole 77e, and these locked holes 77g are adjusted. A locking projection 79g of the rotor 79c is selectively locked. The compression coil spring 79a maintains the state where the grooved shaft portion 79f of the adjusting rotor 79c is inserted into the through hole 77e of one disk 77c of the outer case 77, and the locking projection 79g of the adjusting rotor 79c is connected to the outer case 77. It is comprised so that the state inserted in either of the three to-be-latched holes 77g may be maintained. Further, the torsion coil spring 79b is configured to urge the pair of arm portions 73b and 73b in a direction in which they are brought close to each other. In the state where no load is applied to the pair of arm portions 73b and 73b or the pair of string loose insertion portions 74 and 74, the distance between the ends of the pair of arm portions 73b and 73b, that is, the distance between the pair of columnar portions 73c and 73c is The connection main body 73 loosely fitted to the horizontal portion 11c of the hook 11 is set at an interval that does not leave the horizontal portion 11c. The configuration other than the above is the same as that of the reference embodiment.

  The usage method and operation | movement of the connection tool 70 comprised in this way are demonstrated. First, the pair of ring strings 42b at both ends of the tassel 42 are loosely inserted into the string loose insertion portions 74 of the pair of connecting devices 70, respectively. Next, the pair of string insertion parts 74 and 74 are gripped, and the base ends of these string operation parts 74 and 74 are brought close to each other against the elastic force of the torsion coil spring 79 b, and the pair of arm parts 73 b of the connection main body 73. 73b, the distance between the pair of cylindrical bodies 73c, 73c is larger than the diameter of the horizontal portion 11c of the tuft 11, and the connection body 73 is loosely fitted to the horizontal portion 11c of the tuft 11 (FIG. 13 ( a) and FIG. 14 (a)). Further, the tuft portion of the tassel 42 is wound around the curtain, and in this state, the connection main body of the other connection tool (not shown) into which the other ring string (not shown) of the tassel 42 is loosely inserted is connected to the horizontal portion of the tuft 11. It is loosely fitted to 11c. In this state, when a load (for example, a load of 2 kg or more) in a direction in which the tassel 42 is pulled away from the tuft 11 acts on the tassel 42, one or both of the pair of connectors 70, In this embodiment, both ends of the separating portion 73a of one connecting tool 70 are elastically deformed in a direction away from each other along the outer peripheral surface of the horizontal portion 11c of the tuft 11. For this reason, the connecting tool 70 is detached from the tuft 11 together with the tassels 42 (FIGS. 13B and 14B). As a result, the ring state of the tassel 42 can be reliably released, so that a child or an elderly person can be quickly released from the tangling of the tassel 42. Further, when the connection tool 70 is detached from the tuft 11 together with the tassels 42 and the connection tool 70 is separated from the tuft 11, the both ends of the disconnecting portion 73a of the connection main body 73 are caused by the elastic force of the connection main body 73, specifically, the torsion coil. Since the connection body 73 returns to a substantially C shape by the elastic force of the spring 79b, the connection tool 70 can be used repeatedly any number of times.

  Next, a method of adjusting the elastic force that widens the distance between the pair of columnar bodies 73c and 73c at both ends of the connection body 73, that is, the tips of the pair of arm portions 73b and 73b, will be described. First, when a minus driver (not shown) is inserted into the groove of the grooved shaft portion 79f and the adjustment rotor 79c is pushed into the case 76, the grooved shaft portion 79f of the adjustment rotor 79c is one disk of the outer case 77. The locking projection 79g of the adjusting rotor 79c is released from the locked hole 77g of the outer case 77, while being released from the through hole 77e of 77c. As a result, the adjustment rotor 79 c can be rotated relative to the outer case 77. Next, when the adjusting rotor 79c is rotated by a minus driver, and the locking projection 79g faces the desired locked hole 77g among the three locked holes 77g, the pushing force of the adjusting rotor 79c by the minus driver is increased. When released, the grooved shaft portion 79f is inserted into the through hole 77e of the one disc 77c of the outer case 77, and the locking projection 79f is inserted into the desired locked hole 77g. As a result, it is possible to adjust the elastic force that widens the gap between the pair of columnar bodies 73c and 73c at both ends of the separation portion 73a of the connection main body 73, that is, the pair of arm portions 73b and 73b. The load of a predetermined value or more in the direction in which the tassels 42 are pulled away from the tuft 11 in a state of loosely fitting to the 11 horizontal portions 11c can be adjusted within a range of 2 to 6 kg, for example.
