In the figure, 10 indicates a stopper, and this stopper 10 is used, for example, to stop both ends 31, 32 of the lace 30 of the lace shoe 20 as shown in FIG. As shown in FIG. 3, the stopper 10 roughly includes a stopper body 40 and a rotary knob 50. As shown in FIGS. 1 and 3 to 5, the stopper body 40 is located within the space between the two insertion holes 41 and 41 through which the both ends 31 and 32 of the string 30 pass, respectively. And a shaft hole 42 for

More specifically, as shown in FIG. 3, the stopper body 40 includes a bottom wall 43 that is long and horizontally long and has a substantially elliptical shape in plan view, and both left and right ends along the long axis of the bottom wall 43. A pair of left and right side walls 44, 44 are provided so as to project upward from the respective parts and face each other while being separated from each other on the left and right. The stopper body 40 is integrally formed of, for example, a thermoplastic resin having appropriate elasticity and rigidity. Further, for example, a pigment is mixed in the thermoplastic resin to improve the fashionability. Further, the thermoplastic resin is mixed with, for example, a fluorescent paint to improve the operability at night, and it is possible to secure the pedestrian's safety by making it appear in the dark by the light of the car.

As shown in FIGS. 1 and 3, the two insertion holes 41 penetrate the bottom wall 43 in a circular cross section, and are formed along the inner surfaces of the both side walls 44 facing each other. Then, each insertion hole 41 is made slightly larger than the diameter of the string 30. Further, as shown in FIGS. 1 and 3, the shaft hole 42 penetrates the bottom wall 43 above and below in a circular cross section, and is located substantially at the center of both insertion holes 41.

As shown in FIGS. 1 and 3, the both side walls 44 have inner surfaces facing each other curved in an arc shape with the shaft hole 42 as a center. In addition, a guide groove 45, which is recessed in a semicircular shape, is formed along the edge of each insertion hole 41 at substantially the center of each inner surface of each side wall 44. The semi-circular diameter of each proposal groove 45 is set to be equal to or smaller than the diameter of the string 30. As shown in FIGS. 1 and 3, the rotary knob 50 has a shaft portion 51 rotatably supported in a shaft hole 42 of a stopper body 40, and a lateral projection from a tip end portion of the shaft portion 51. And a knob 52 that rotates around the shaft hole 42 within the space between both side walls 44.

The rotary knob 50, like the stopper body 40, is integrally formed of, for example, a thermoplastic resin having appropriate elasticity and rigidity. Further, the thermoplastic resin is mixed with a pigment or fluorescent paint of the same color as the stopper body 40. Of course, when molding the rotary knob 50, a pigment or fluorescent paint of a color different from that of the stopper body 40 may be mixed. As shown in FIGS. 1 and 3, the shaft portion 51 has a cylindrical shape having an outer diameter substantially equal to the inner diameter of the shaft hole 42 of the stopper body 40. At the lower end of the shaft portion 51, a large diameter portion 53 that opens upward in a folded umbrella shape is formed, and the maximum outer diameter of the large diameter portion 53 is set to be larger than the inner diameter of the shaft hole 42. ing. The distance from the upper end of the large diameter portion 53 to the lower surface of the knob 52 is set to be substantially equal to the plate thickness of the bottom wall 43 of the stopper body 40.

Further, as shown in FIGS. 1 and 3, the knob portion 52 has a substantially flat elliptical shape that is long in the left and right, and its major axis is equal to or less than the facing interval of the both side walls 44 of the stopper body 40, here. The settings are almost equal. The minor diameter of the knob portion 52 is set to be equal to or less than the distance between the left and right insertion holes 41 of the stopper body 40. As shown in FIG. 3, the left and right outer side surfaces of the knob portion 52, which are orthogonal to the long axis, are curved in a convex shape with substantially the same curvature as the curved inner side surfaces of the both side walls 44. The left and right outer side surfaces of the knob 52, which are orthogonal to the short axis, are linearly formed in parallel with the long axis. On each of the linear outer surfaces, a plurality of swelling semi-circular cross-sections, here three projections 54 for slip prevention are formed at predetermined intervals.

Next, an assembling procedure of the stopper 10 including the stopper main body 40 and the rotary knob 50 having the above-described configurations will be described. First, the shaft portion 51 of the rotary knob 50 may be inserted from the upper side to the lower side in alignment with the shaft hole 42 of the stopper body 40. When the shaft portion 51 of the rotary knob 50 is inserted, its large diameter portion 53 engages with the shaft hole 42 of the stopper body 40. When the shaft portion 51 is strongly inserted in this state, the large diameter portion 53 is pushed by the inner edge of the shaft hole 42 and passes through the shaft hole 42 while being recessed against its elasticity.

When the large-diameter portion 53 passes through the shaft hole 42, as shown in FIG. 1, the large-diameter portion 53 expands under the lower surface of the bottom wall 43 of the stopper body 40 by its elastic restoring force, and its upper end portion. By contacting the lower surface of the bottom wall 43, the shaft portion 51 of the rotary knob 50 is prevented from coming out of the shaft hole 42 of the stopper body 40. At the same time, the rotary knob 50 is rotatably supported in the shaft hole 42 of the stopper body 40 about the shaft portion 51 thereof.

Next, the operation of the stopper 10 in the assembled state will be described below with reference to FIGS. First, as shown in FIG. 4, when the long axis of the knob 52 of the rotary knob 50 is orthogonal to the long axis of the stopper body 40 in a cross shape, both insertion holes 41 of the stopper body 40 are opened. ing.

In this open state, both ends 31 and 32 of the lace 30 of the lace shoe 20 are fitted to both insertion holes 41 of the stopper body 40 as shown in FIG. . At this time, the tightening strength of the lace 30 of the lace shoe 20 can be adjusted by shortening the lengths of the ends 30 and 32 of the lace 30 that are pulled out. After that, hold the knob 52 of the rotary knob 50 and rotate the knob 52 around the shaft 51 so that the long axis of the knob 52 is parallel to the long axis of the stopper body 40 as shown in FIG. Let

When the knob portion 52 is rotated, its outer side surfaces which bulge out in a semicircular shape in the longitudinal direction engage with the inner side surfaces of the side walls 44 of the stopper body 40 which are recessed in an arc shape. At this time, the tops of the two outer surfaces of the knob 52 that bulge into a semicircle contact the outer edges of the inner surfaces of the side walls 44. Here, if the knob 52 is rotated more strongly, the side walls 44 open to the left and right to widen the facing interval, and at the position rotated by 90 degrees, the knob 52 fits within the interval of the side walls 44. . When the knob 52 is fitted, both side walls 44 are restored by the elastic restoring force of the resin, and the knob 52 is locked within the space between the side walls 44. Further, in this process, it is easily understood that the operator is given a click feeling and the knob 52 is locked within the space between the side walls 44.

In this way, when the knob portion 52 is fitted into the space between the side walls 44, both the insertion holes 41 of the stopper body 40 are partially closed by the knob portion 52 of the rotary knob 50, as shown in FIG. Get off. At this time, the both ends 31, 32 of the cord 30 are pressed against the semicircular guide grooves 45 of the both side walls 44 of the stopper body 40, and the guide grooves 45 and the knob 52 are semicircular in the longitudinal direction. It is sandwiched between the bulging outer surface and the outer surface and is crushed into a semicircular cross section.

Therefore, the both ends 31, 32 of the string 30 are prevented from moving in the longitudinal direction by the frictional resistance between the inner peripheral surface of each guide groove 45 and the outer peripheral surface of the semicircular outer surface of the knob 52. This prevents the lace 30 of the lace shoe 20 from being loosened. On the other hand, in order to loosen the lace 30 of the lace shoe 20, the knob 52 may be rotated by approximately 90 degrees. When the knob 52 is rotated by about 90 degrees, both the insertion holes 41 of the stopper body 40 can be opened, so that the lengths of both ends 31, 32 of the string 30 can be freely adjusted. .

In the embodiment shown in the drawings, the shoe 10 of the fastener 10 is used, but the invention is not limited to this, and the shoe may be used as a shoe stopper for closing the opening edge of clothes or bags. Further, although the knob portion 52 of the rotary knob 50 is formed in a plane elliptical shape, it is not limited to this and may be formed in an elliptical shape or a polygonal shape. Furthermore, although the large diameter portion 53 at the tip of the shaft portion 51 of the rotary knob 50 is formed in an umbrella shape, the present invention is not limited to this and may be an anchor shape or a canoe shape. Further, the large diameter portion 53 may be a separate body.
