用ストツパーに係るものである。[Detailed description of the invention] [Industrial field of application] The present invention relates to a string stopper used for draw strings, wrapping strings, strings that prevent people from opening their mouths, etc. It has a hollow outer casing with a fixed side sawtooth provided in the outer casing and an elastic leg equipped with a movable side sawtooth on the movable end, and between these fixed side sawtooth and movable side sawtooth. When the string is inserted and both sides of the string protrude from the string passage hole to the outside of the outer casing, and a traction force is applied to one of the extending sides in the direction away from the outer casing, the movable saw teeth follow the string. By approaching the fixed-side sawteeth, the string is strongly bitten to prevent the string from moving, and when a traction force is applied to the other protruding side in the direction away from the outer casing, the movable-side sawtooth In a string stopper that follows the string and moves away from the fixed saw teeth, the above-mentioned biting is eliminated and the string is allowed to move.
The immovable ends of the elastic legs are attached to the wall of the outer casing so as to be able to slide slightly in parallel to the direction in which the traction force is applied to the string, and a vertical groove into which a part of the string is indented is provided at the point where the sawtooth string comes into contact. The present invention relates to a string stopper characterized by being perforated.

ーズではない等の弊があつた。 Conventionally, this type of string stopper has not been provided with the above-mentioned longitudinal grooves (which function to prevent the string from twisting back), so it is difficult to apply traction force, especially when the string is a twisted string. When untwisting occurs, it is not always possible to ensure sufficient engagement, allowing the string to move, and the immovable end of the elastic leg can slightly slide in parallel to the direction in which the traction force is applied to the string. Since the cord is not attached to the wall of the outer casing, the function of preventing the movement of the string is not necessarily sufficient, and the operation of allowing movement of the string is not necessarily smooth.

である。 In the present invention, the immovable end of the elastic leg is attached to the wall of the outer casing so that it can slide slightly in parallel to the direction of the traction force applied to the string, and a part of the string is invaginated at the point where the string comes into contact with the sawtooth. It is an attempt to solve the above-mentioned problems by providing vertical grooves.

のである。 When the string A is pulled in the direction indicated by the white arrow, the movable ends of the elastic legs 8, 8', 15, 15', and 17 move away from the fixed saw teeth 4, 4', and , 4' and the movable side sawtooths 9, 9' are widened to enable the pulling and tightening of the string A, and when pulled in the direction indicated by the thick solid arrow, the elastic legs 8, 8', 15 , 15', 17 move closer to the fixed side saw teeth 4, 4' and try to narrow the above distance, so the fixed side saw teeth 4, 4' and the movable side saw teeth 9, 9' strongly resist the string A. A part of the string A is bitten and invaginates into the vertical groove 10. In other words, due to the biting and invagination, even if the string I is a twisted string, it is effective in preventing twisting and untwisting, so the twisting does not occur and the biting can be secured sufficiently, so the movement preventing function is not lost. and elastic legs 8, 8', 15, 15',
When the movable end of 17 moves away from or near the fixed saw teeth 4, 4', the elastic legs 8, 8',
15, 15', 17 are all inserted into the insertion pins 11, 1
Since the string can slide within the insertion holes 12, 12', the movement of the string can be smoothly performed.

パー。 It has a hollow outer casing with a string passage hole on both upper and lower walls, a fixed side sawtooth provided in the outer case, and an elastic leg with a movable side sawtooth at a movable end. When a string is inserted between the saw teeth on the movable side and both sides of the string protrude out of the outer casing from the string passage hole, and a traction force is applied to one of the protruding sides in the direction away from the outer casing, the string becomes movable. The side serrations follow the string and approach the fixed side serrations, thereby tightening their grip on the string to prevent the string from moving, and also exerting a traction force on the other protruding side in the direction away from the outer casing. In the string stopper, the movable side saw teeth follow the string and move away from the fixed side saw teeth, thereby eliminating the above-mentioned biting and allowing the string to move. is attached to the wall of the outer casing so as to be able to slide slightly parallel to the direction in which the traction force is applied to the string, and a vertical groove into which a part of the sawtooth string is indented is bored at the point where the sawtooth string comes into contact.
