Description

[Detailed description of the invention] [Field of industrial application] The present invention is designed to prevent the end of a draw string inserted into a string passage in clothing, bags, etc. from being pulled into the string passage, or when the draw string is This relates to a drawstring stopper used to prevent the drawstring from slipping out of the passage.

[Conventional technology]

Conventionally, this type of string removal stopper has been made of a combination of a band having holes at both ends and the center, a pair of rod-shaped clamps having holes through which screw rivets are passed, and tightening screw rivets. A bundle clamping tool is known from Japanese Utility Model Publication No. 2-8665.

[Problem that the invention attempts to solve]

However, with this structure, the string is bent into a U-shape, a band is wrapped around the aligned part, the ends of the band are overlapped in the middle of both strings, and the overlapping part is hit in a direction parallel to the string. This method requires the troublesome method of tightening the strap by abutting bar-shaped clamps on the front and back of the outer surface of the strap, applying screw rivets through holes in the strap surface and between the two strings, and tightening the distance between the clamps. Not only that, but the U-shaped bent part of the string is completely exposed to the outside, so if this U-shaped bent part gets caught on another object, the short end of the bent part of the string becomes more unstable than the strap. There were problems, such as the risk of slipping out.

[Means for solving problems]

The present invention consists of a front member 3 having a wide groove 2 on the back surface with an open end surface 1 and a back cover 4 that fits into the wide groove 2. A boss 5 is provided at the center of the bottom of the wide groove 2. Attach the center of the back cover 4 to the top surface of the
so that when the screw 6 is tightened, the inner surface of the back cover 4 and the bottom of the wide groove 2 are inserted into the wide groove 2, and the drawstring I wrapped around the boss 5 is clamped. The present invention attempts to solve these problems by providing a pull-out stopper for a draw string, which is characterized by the following features.

〔Example〕

A front side member 3 is made of hard plastic and has a wide groove 2 on the back surface with both end surfaces 1 open, and a boss 5 is integrally provided in the center of the bottom of the wide groove 2, and a screw hole 7 is provided on the top surface of the boss 5. and separately constitute a back cover 4 made of hard plastic and having a screw hole 8 in the center with a recess 9 into which the boss 5 is fitted, the width being slightly narrower than the wide groove 2, This back cover 4 is fitted into the wide groove 2 and the boss 5
and the fitting recess 9 and both sides 1 of the back cover 4.
0 and 10' and the inner surfaces of both sides of the wide groove 2, insert the screw 6 into the screw hole 8, screw the threaded part into the screw hole 7, and then attach the back cover to the front member 3. 4 is removably attached.

[Functions and effects of the invention]

The present invention has the above-mentioned structure, so in order to use it, first remove the screws 6 and separate the back cover 4 from the front member 3. Fold it into a shape and insert the U-shaped part around the boss 5 in the wide groove 2, return the back cover 4 to the wide groove 2, and tighten the screws 6 to connect the inner surface of the back cover 4 and the wide groove 2. It is sufficient to provide a means for clamping the drawstring A with the bottom surface, and when adjusting the effective length of the drawstring A, slightly loosen the tightening of the screw 6, and in this loosened state. Simply change the position where the drawstring is inserted into the wide groove 2, and then tighten the screw 6 back.This method involves bending the string into a U-shape and attaching the strap to this part. It is extremely simple compared to the above-mentioned known method, which requires troublesome work such as winding the band and connecting the three holes provided in the band and the holes of the pair of rod-shaped clamps with each other. In the present invention, the U-shaped bent portion at the end of the string is hidden and held between the back and front members and is not exposed to the outside, so if this bent portion gets caught on another object, the shorter end of the string There is no risk of the end portion accidentally coming out from between the back cover and the surface member, and the present invention has the effect of sufficiently solving the above-mentioned problems.
