And a hollow cylindrical male body 40 having a communication hole 41 through which 10 can pass.

As shown in FIGS. 2 to 4, the female body 30 has a hollow cylindrical shape of a truncated cone shape, and is integrally formed of a resin such as POM having appropriate elasticity and rigidity. . As shown in FIGS. 2 to 4, the insertion hole 31 penetrates the female body 30 in the vertical direction, and has a substantially circular cross section as a whole. At the open upper edge of the insertion hole 31, as shown in FIGS.
An overhanging edge 32 is formed from an inner peripheral surface of the overhang 30 in a rectangular shape. The inner peripheral edge of the overhanging edge 32 acts as a cam surface, and as shown in FIG.
The pair of left and right short edges 32a face each other in the left-right direction with the insertion hole 31 interposed therebetween and are relatively short in the front-rear direction.
b, 32b, and a corner edge 32c that connects the adjacent long edge 32a and short edge 32b in an arc shape.

Therefore, as shown in FIG. 4, the upper end of the opening of the insertion hole 31 has a long edge 32a, a short edge 32b, and a corner edge 32c.
, And more specifically, a substantially rectangular shape long in the left-right direction. At the lower end of the opening of the insertion hole 31, as shown in FIGS. 2 and 3, an annular concave portion 33 is formed along the inner peripheral surface of the female body 30 so as to have a semicircular cross section in a radially outward direction. I have.

As shown in FIGS. 2 to 4, a plurality of ribs 34 projecting radially and extending vertically in the height direction of the female body 30 and having a semicircular cross section are formed on the outer peripheral surface of the female body 30. Are formed. The rib 34 is for preventing slippage when the female body 30 is rotated. As shown in FIG. 4, the rib 34 substantially crosses along the longitudinal central axis and the lateral central axis of the upper end of the opening of the insertion hole 31. Four lines are formed in the direction.

On the other hand, as shown in FIGS. 2, 3 and 5, the male body 40 is substantially symmetrical with respect to the male body 40 in the vertical direction, and has a frusto-conical hollow cylindrical body 42 which is turned upside down. , This cylinder body 42
From the large-diameter upper edge part, it becomes narrower and extends upward short,
A hollow cylindrical neck 43 protruding into the insertion hole 31 of the female body 30,
It has a pair of elastic arms 44, 44 extending upwards facing each other while maintaining an interval through which the string 10 passes from the thinned neck 43, and is integrally formed of, for example, a resin such as POM having appropriate elasticity and rigidity. Is formed.

As shown in FIGS. 2, 3, and 5, the communication hole 41 penetrates the cylinder main body 42 and the neck 43 in the vertical direction, and has a substantially rectangular cross section in which two opposite sides are longer than the other two opposite sides. Has formed. The two elastic arms 44 are shown in FIGS.
As shown in the figure, along the two long sides of the communication hole 41, the neck 43
Respectively extend substantially vertically upward from opposing upper edges. The distal ends of both elastic arms 44 are formed with distal end clamping portions 45 which are opposed to each other and bent inwardly in an L-shaped cross section.

As shown in FIGS. 2, 3 and 5, the front end holding portion 45 has a linear outer edge 45a along the inner surface of the short edge 32b of the overhanging edge 32 of the female body 30 and an insertion hole 31 of the female body. And an inner edge 45b concaved in an arc shape, and a side edge 45c bulging in an arc shape along a corner edge 32c of the overhanging edge 32, connecting the inner edge 45b and the outer edge 45a to each other. And the inner edge 45b
As shown in FIG. 2, when viewed from the side, the section has a triangular cross section that is tapered and pointed.

As shown in FIGS. 2, 3 and 5, an outer circumferential surface of the neck portion 43 has an annular convex portion 46 which fits into the annular concave portion 33 of the female body 30 and bulges radially outward in a semicircular cross section. Are formed. Further, on the outer peripheral surface of the cylinder main body 42, FIGS.
As shown in the figure, a plurality of ribs 47... Similar to the ribs 34 on the outer peripheral surface of the female body 30 are formed. More specifically, rib 4
As shown in FIG. 5, four lines 7 are formed substantially in the cross direction along the longitudinal central axis and the lateral central axis of the communication hole 41.

In order to connect the female body 30 and the male body 40 to each other, as shown in FIGS. 1, 6 and 7, both the male body 40 and the male body 40 are aligned with the open lower surface of the insertion hole 31 of the female body 30. The elastic arm 44 may be inserted upward from below. At this time, the neck 43 of the male body 40
However, as shown in FIGS. 1 and 6, the female body 30 is inserted deeply until it protrudes into the insertion hole 31. When the neck 43 of the male body 40 protrudes into the insertion hole 31 of the female body 30, the annular projection 46 of the neck 43 is inserted into the insertion hole 31.
The snap fits into the annular concave portion 33 in 31.

For this reason, the fitting of the annular concave portion 33 and the annular convex portion 46 prevents the neck portion 43 of the male body 40 from coming out of the insertion hole 31 of the female body 30 and the female body 30 and the male body 40 They are rotatably connected to each other. Also, in the assembled state of the stopper 20, the distal end holding portions 45 of the two elastic arms 44 of the male body 40 are in the positions shown in FIGS.
As shown in FIGS. 6 and 7, the female body 30 is located inside the overhanging edge 32.

For example, the state shown in FIGS.
10 shows the unlocked state. In this unlocked state, the male
As shown in FIG. 7, the front end holding portions 45 of the two elastic arms 44 are located within a space between the opposite short edges 32b of the overhanging edge 32 of the female body 30. For this reason, the two elastic arms 44 of the male body 40
Are relatively far apart, and the facing distance between the inner edges 45b thereof is larger than the diameter of the cord 10, as shown in FIGS.

On the other hand, when the female body 30 and the male body 40 are connected to each other, as shown in FIG.
In some cases, the female body 30 is located within the space between the opposed long edges 32a of the overhanging edge 32. This state is a locked state of the string 10. That is, since the inside of the overhanging edge 32 is opened in a rectangular shape that is long in the left-right direction, the interval between the opposed long edges 32a is shorter than the interval between the opposed short edges 32b. caused by.

For this reason, the distance between the two elastic arms 44 of the male body 40 is relatively close as shown in FIG.
The facing distance between b is smaller than the diameter of the string 10. To pass the string 10, the stopper 20 is in an unlocked state as shown in FIGS. Note that the conversion from the locked state to the unlocked state may be performed by rotating either the female body 30 or the male body 40 with respect to the other, which will be described in detail later.

As shown in FIG. 6, in order to pass the string 10 through the stopper 20 in the unlocked state, the string 10 is folded in a loop shape, and the folded ends are aligned with the insertion holes 31 of the female body 30. Just pass it through. The folded both ends of the cord 10 may be simultaneously passed through the insertion holes 31 of the female body 30 in an aligned state, or may be passed sequentially one by one.

When the string 10 is passed through the insertion hole 31 of the female body 30, the string 10
As shown in FIGS. 1, 6 and 7, both ends of the male body 40 are clamped.
Through the interval of 45, further through the communication hole 41,
Guided outward. As shown in FIG. 6, both ends of the folded string 10 are passed through the insertion holes 31 of the female body 30 and are drawn out of the communication holes 41 of the male body 40, respectively.

The stopper 20 changes the diameter of the loop of the string 10 while changing the length of the draw-out margin of the string 10. For example, although not shown, the string 10 is passed through the opening edge of the hood of the raincoat, and by changing the length of the draw-out margin of the string 10 coming out of the stopper 20, the opening diameter of the hood can be reduced,
Can be expanded. Then, in order to lock the string 10, one of the female body 30 and the male body 40 may be rotated by 90 degrees with respect to the other. The rotation direction of the female body 30 and the male body 40 may be either clockwise or counterclockwise in FIG.

When either the female body 30 or the male body 40 is rotated, the front end holding portions 45 of the male body 40 are relatively positioned inside the overhanging edge 32 of the female body 30 as shown in FIG. Rotated. When the two front end holding portions 45 of the male body 40 rotate, the arc-shaped curved side edge 45c extends along the same arc-shaped curved corner edge 32c of the overhanging edge 32, and extends linearly following the corner edge 32c. It moves toward a certain direction of the edge 32a. In this process, while the front end holding portions 45 of the male body 40 gradually approach,
Both inner edges 45c bite into the outer periphery of the cord 10.

Then, when the side edge 45c of the front end holding portion 45 reaches the boundary from the corner edge 32c of the overhanging edge 32 to the linear long edge 32a, the front end holding portion 45 is rapidly rotated. That is, the two elastic arms 44 are slightly opened due to the elastic restoring force, and the linear outer edge 45a is, as shown in FIG.
The overhanging edge 32 is received by hitting the straight long edge 32a, and the rotation of the female body 30 and the male body 40 is stopped.

For this reason, the operator is given a click feeling and can know that the stopper 20 is locked. When the stopper 20 is locked, as shown in FIG. 8, both inner edges 45 c of both end holding portions 45 of the male body 40 bite into the outer periphery of the cord 10,
Movement of the string 10 in the longitudinal direction is prevented.

On the other hand, to return the stopper 20 to the unlocked state, one of the female body 30 and the male body 40 is
It may be rotated back by 0 degrees, or it may be rotated back by 90 degrees in the direction of rotation at the time of locking, and in any direction, following the reverse process as described above, It returns to the unlocked state shown in 1,6,7.

In the embodiment shown in the drawings, the male body
Although the pair of the elastic arms 44 are formed so as to face each other, the number of the elastic arms is not limited to two, but may be as many as three. Further, serrations may be formed on the inner edge 45b of both elastic arms 44 to make it easier to bite into the outer periphery of the cord 10. On the other hand, by mixing the pigment into the resin of the female body 30 and the male body 40, not only can the stopper 20 be molded into various colors, but also by making the colors of the female body 30 and the male body 40 different from each other. Alternatively, a colorful stop 20 can be provided.

Also, the overall shape of the stopper 20 is not limited to the barrel shape, and various modifications such as an egg shape are possible. In addition, stop
20 may be used not only for the opening edge of the raincoat hood but also for the opening edge of bags as well as clothing.
