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 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 end of the elastic leg 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 when the movable side sawtooth approaches the stationary side sawtooth during operation, it slides into contact with the fixed side sawtooth, and the end of the elastic leg A movable side guide part and a fixed side guide part configured to forcibly bring the movable end close to the fixed side sawtooth are provided on the movable end of the elastic leg and the wall surface of the outer casing, and furthermore, the part where the sawtooth string comes into contact. This invention relates to a stopper for a string, characterized in that a vertical groove into which a part of the string invaginates is bored.

[Problems that conventional techniques and ideas attempt to solve]

Conventionally, this type of string stopper does not have the above-mentioned vertical grooves (which function to prevent the string from twisting back) on the sawtooth, so it is difficult to apply traction force, especially when the string is a twisted string. When the string is pulled, untwisting may occur, making it impossible to ensure sufficient engagement and allowing the string to move.Also, the immovable end of the elastic leg may slightly slide parallel to the direction in which the traction force is applied to the string. However, since it is not attached to the wall of the outer casing, the function of preventing the string from moving is not necessarily sufficient, and the movement of the string is not always smooth. The movable side guide part and the fixed side guide part, which are configured to slide into sliding contact and force the movable end of the elastic leg to approach the fixed sawtooth, are not provided on the movable end of the elastic leg and the wall surface of the outer casing. However, there were disadvantages such as the above-mentioned bite was not necessarily strong.

[Means for solving problems]

In this invention, the immovable end of the elastic leg is attached to the wall of the outer casing so that it can slide slightly parallel to the direction in which the traction force acts on the string, and when the movable side sawtooth approaches the fixed side sawtooth during operation, the elastic leg comes into sliding contact with the fixed end. A movable side guide part and a fixed side guide part are provided on the movable end of the elastic leg and on the wall of the outer casing, and the movable side guide part and the fixed side guide part are configured to forcibly bring the movable end of the elastic leg close to the fixed side sawtooth, and the string is attached to the sawtooth. This is an attempt to solve the above-mentioned problems by creating a vertical groove into which a part of the string is indented at the point of contact.

[Effect]

Each of the above-mentioned embodiments is used through a cord as shown in the drawings. In the first embodiment, when the string I is passed through this, the string I is also passed through the through holes 19 and 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 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 A is a twisted string, it is effective in preventing twisting and untwisting, so the twisting does not occur and the biting is sufficiently secured, so the movement preventing function is not lost. and elastic legs 8, 8', 15, 1
When the movable ends of 5' and 17 move away from or near the fixed side sawtooths 4 and 4', the elastic legs 8 and
8', 15, 15', 17 are all inserted into the insertion pins 11,
11' slides within the insertion holes 12, 12', allowing the string to move smoothly.
Furthermore, the movable side guides 21, 21' and the fixed side guide 2
2, the above-mentioned biting is made stronger.

Claims (1)

[Scope of utility model registration request] 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 when the movable side sawtooth approaches the fixed side sawtooth during operation, it slides into contact with the movable end of the elastic leg to move the movable end of the elastic leg to the fixed side. A movable guide portion and a fixed guide portion configured to forcibly approach the sawtooth are provided on the movable end of the elastic leg and on the wall of the outer casing, and a portion of the cord is attached to the area where the sawtooth string comes into contact. A stopper for a string characterized by having a vertical groove in which the part is recessed.
