  As shown in FIG. 3, a plurality of claws 30 b are formed on the side surface of each string gripping part 30 that faces the opening of the string insertion part 26. In the present embodiment, the four claws 30b are formed at equal intervals. Each claw 30b has a triangular cross section, and the tip of the claw 30b is inserted into the string S so as to bite the string S.

Next, the operation of the string fastener of this embodiment will be described with reference to FIGS. When fixing the leading end of the string to the string fastener, first, the end of the string is inserted from the insertion port 11a of the socket 11, as shown in FIG. The string is inserted through the insertion hole 11 b while being guided by the inner surface of the socket 11. Further, it is inserted into the inner insertion hole 17 of the string fixing part 12 through the inner insertion port 16 while being guided by the inner inclined surface 18 provided at the base end part 15 of the string fixing part 12.

  As shown in FIG. 5A, the end of the string S inserted through the insertion hole 11 b and the inner insertion hole 17 reaches the tip of the guide portion 25. In addition, the angle which each string holding part 30 makes is set to (theta) 1, and the position of the string holding part 30 shown to Fig.5 (a) in which the angle (theta) 1 becomes the maximum is hereafter called rotation start position. Moreover, the position of the string fixing portion 12 shown in FIG. 5A in a state where no pressing force is applied to the pressing portion 27 is hereinafter referred to as a slide start end position.

  When the string S is inserted through the socket 11 and the string fixing part 12, a pressing force is applied to the pressing part 27. At this time, for example, while holding the socket 11 with one hand, the pressing surface 27a is pressed with the other hand. As a result, a shearing force acts between the string fixing part 12 pushed into the socket 11 and the socket 11, and the string fixing part 12 and the socket 11 are sheared at the connecting part 20 as shown in FIG. Thus, the connection between the string fixing portion 12 and the socket 11 is released. At this time, as described above, the socket 11 may be fixed with one hand and the string fixing portion 12 may be pressed with the other hand, so that the operation is easy.

  Further, when the connection is released, the string fixing portion 12 is in a state where a part of the base end portion 15 is accommodated inside the socket 11, so that it is guided into the socket 11 as it is, and the inner side surface of the socket 11 It is inserted while sliding. When the entire base end portion 15 is inserted into the socket 11, the string gripping portion 30 starts to be inserted into the socket 11. At this time, as shown in FIG. 5 (c), the outer surface 30 a of each string gripping portion 30 comes into contact with the inner surface of the socket 11, so that the string gripping portions 30 approach each other (the guide portion 25 side). ) In response to this force, the thin-walled portion 31 that is most flexible among the string gripping portions 30 bends inward. As a result, the string gripping portion 30 rotates from the rotation start end position in a direction close to each other and in a direction in which the angle θ1 decreases.

  When the pressing portion 27 is further pressed, as shown in FIG. 5D, the string gripping portions 30 are rotated to positions (rotation end positions) that are parallel to each other (angle θ = 0 °). When the string gripping part 30 is arranged at the rotation end position, the claw 30b formed on the string gripping part 30 is inserted into the string S to the maximum, and the string S is bitten with respect to the string fixing part 12. . Then, the string gripping portion 30 is pushed into the socket 11 while maintaining the rotation end position.

  As shown in FIG. 6, when the pressing portion 27 is pressed to a position where the pressing surface 27 a of the pressing portion 27 is substantially flush with the end surface 11 c of the socket 11, the rotation preventing protrusion 28 is inserted into the rotation preventing groove 13 ( (Not shown). Further, the extraction preventing projection 29 is inserted into the socket 11 from the tip of the inclined surface 29a, and the entire extraction preventing projection 29 is eventually overlapped with the extraction preventing hole 14 to be fitted. The sliding movement of the string fixing portion 12 with respect to the socket 11 is stopped by the fitting of the anti-rotation protrusion 28 and the anti-rotation groove 13 and the engagement of the anti-extraction protrusion 29 and the anti-extraction hole 14. The string fixing portion 12 is fixed to the socket 11 (slide end position). At this slide end position, the string fixing portion 12 is accommodated in the socket 11 with the string S fixed.

  As described above, when the end of the string is fixed to the string fastener, the connection between the string fixing unit 12 and the socket 11 is released, the string S is clamped by the rotation of the string gripping unit 30, and the string fixing unit 12 The socket 11 can be fixed by one easy operation of fixing the socket 11 with one hand and pressing the string fixing portion 12 toward the socket 11 with the other hand.

The string fastener fixed to the end of the string S prevents fraying of the end of the string S, and is normally used without being removed from the string S. Since the string fixing part 12 is not rotatable with respect to the socket 11, the string S is not twisted by the rotation of the string fixing part 12. Further, even if an unintended force is applied in a direction in which the string fixing portion 12 is pulled out from the socket 11, it can be easily pulled out by the engagement between the pull-out preventing projection 29 and the pull-out preventing hole 14. Not. For this reason, a highly rigid string fastener can be provided.
