Description

[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 with a movable side sawtooth at the tip, and a string is connected between the fixed side sawtooth and the movable side sawteeth. is inserted, and both sides of the string protrude from the outer casing through the string passage hole,
When a traction force is applied to one of the protruding sides in the direction away from the outer casing, the movable side sawteeth follow the string and approach the fixed side sawteeth, thereby tightening the grip on the string and preventing the string from moving. In addition, when a traction force is applied to the other protruding side in the direction away from the outer casing, the movable saw teeth follow the string and move away from the fixed saw teeth, thereby eliminating the above-mentioned biting and tightening the string. This relates to a stopper for a string which is adapted to allow movement and is characterized in that a vertical groove into which a part of the sawtooth string comes into contact is bored in the part where the sawtooth string comes into contact. be.

[Problems that conventional techniques and ideas attempt to solve]

Conventionally, this type of string stopper has not been provided with the above-mentioned vertical grooves in the saw teeth. For this reason, it did not have a function to prevent the string from twisting as described later. Therefore, especially when the string is a twisted string, untwisting occurs when a traction force is applied, and sufficient engagement cannot always be ensured, allowing the string to move.

[Means for solving problems]

The present invention attempts to solve the above-mentioned problems by creating a vertical groove into which a portion of the string is indented at the point where the string comes into contact with the sawtooth.

[Effect]

Each of the above-mentioned embodiments is used through a cord as shown in the drawings. In the first embodiment, when passing the string A through this, the string I is also passed through the through holes 19, 19' of the auxiliary member 18 for squeezing, and the drawing force to be described later is halved. This is what is shown.

When the string A is pulled in the direction indicated by the white arrow, the elastic legs 8, 8', 15, 15', 17 move away from the fixed saw teeth 4, 4', and the fixed saw teeth 4, 4' move away from the fixed saw teeth 4, 4'. By widening the distance between the movable saw teeth 9 and 9', it is possible to tighten the string A, and when the string is pulled in the direction indicated by the thick solid arrow, the elastic leg 8,
Since the saw teeth 8', 15, 15, and 17 move closer to the fixed side saw teeth 4, 4' and try to narrow the above-mentioned interval, 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, the biting and invagination prevent the string from moving and twisting. Even when the string is a twisted string, it is effective in preventing twisting, so that the twisting does not occur and sufficient biting can be ensured, so that the movement preventing function is not lost.

[Effect of idea]

Since the present invention is as described above, it has excellent effects that can completely achieve the intended purpose.

Claims (1)

[Scope of utility model registration request] It has a hollow outer casing with string passage holes in both upper and lower walls, fixed side sawtooths provided in the outer case, and elastic legs with movable side sawtooths at the tips, these fixed side sawtooths, 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 is inserted into the movable side. The saw teeth follow the string and approach the fixed side saw teeth, 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. When the movable side sawtooth follows the string and moves away from the fixed side sawtooth, the above-mentioned biting is eliminated and the string is allowed to move.The sawtooth string comes into contact with the string stopper. A stopper for a string, characterized in that a vertical groove into which a part of the string is indented is bored at a certain point.
