Description

  The present invention relates to a buckle, and more particularly to a buckle used for a pair of strip pieces provided on a waist portion of a pants.

  A buckle is known which is applied to a pair of strip pieces each having one end sewn on a waist portion of jeans or the like. Such a buckle is used for partially adjusting the waist tightness apart from the belt or for decoration. A conventional buckle is disclosed in, for example, Design Registration No. 955874, and FIG. 12 is a plan view thereof. The buckle 4 includes a substantially convex annular first member 60 and a substantially U-shaped second member 70 that is rotatably connected to the first member 60. The first member 60 includes a base 61 that defines the first opening 63 on the inside, and a head 62 that protrudes from the base 61, and the head 62 has a pressing portion 62b. The second member 70 includes a top portion 71 that receives the holding portion 62 b of the head portion 62 of the first member 60, and leg portions 72 that extend from both ends of the top portion 21, and an end portion of the leg portion 72 is a base portion of the first member 60. 61 is pivotally connected to 61. A second opening 73 is defined inside the second member 70. The connection strip which is one of the pair of strip pieces described above is fixedly connected to the bottom shaft portion 61a of the base 61 of the first member 60, and the other adjustment strip is the first opening 63 of the buckle 4 and then the second. The opening 73 or the second opening 73 is then passed through the first opening 63. Thus, the adjustment strip passed through the buckle 4 is held so as not to come out of the buckle 4 by being sandwiched between the pressing portion 62b of the head portion 62 of the first member 60 and the top portion 71 of the second member 70. The And the waist can be partially tightened or loosened by adjusting the length of the adjustment strip passed through the buckle 4. The adjustment strip passed through the buckle 4 extends so as to cover the head portion 62 of the first member 60 between the first opening 63 and the second opening 73. There is a problem that the portion enters the inside of the head 62 (see S), and the length of the adjustment strip passed through the buckle 4 cannot be adjusted smoothly, or the appearance of the adjustment strip is impaired.

Design Registration No. 955874

  Accordingly, it is an object of the present invention to provide a buckle that does not hinder the length adjustment or appearance of the adjustment strip.

  In order to solve the above-mentioned problems, according to the present invention, a first member made of a metal wire and a second member made of a metal wire connected to the first member so as to be rotatable are provided. The member has a base defining a first opening through which the adjustment strip passes and a head protruding from the base with a width interval narrower than the width of the first opening, the head holding the adjustment strip. A pressing portion, a side portion extending from the pressing portion to the base portion to define the width interval therebetween, and a constricted portion having the narrowest width interval between the both side portions, and the second member is a second member. A buckle is provided that includes a receiving portion that defines an opening and receives a pressing portion, and a connecting portion that connects to a shoulder portion of a base portion of the first member.

  In the buckle according to the present invention, the head portion of the base portion of the first member includes a constricted portion having a width interval narrower than the width of the first opening portion of the base portion through which the adjustment strip is passed and the narrowest width interval. Therefore, it is difficult for the portion covering the head of the base of the first member in the adjustment strip passed through the first opening and the second opening to enter the inside of the head.

  In one embodiment of the present invention, the base includes a bottom shaft portion to which the other end portion of the connection strip having one end portion fixed is connected, and the other end side of the adjustment strip having the one end portion fixed is the second opening portion. Then, the first opening or the second opening and then the first opening are passed, and the adjustment strip passes between the connecting strip and the shoulder at the first opening, and the adjustment strip passes through the holding portion and the receiving portion. To be sandwiched between. One end of each of the connection strip and the adjustment strip is fixed to the waist of the pants, and the other end of the connection strip is connected to the bottom shaft of the base of the first member. Further, the adjustment strip is passed through the second opening, then the first opening, or the second opening, and then the first opening, and the length of the passage is adjusted, thereby adjusting the tightening of the waist of the pants and the like. Can do.

  In one embodiment of the present invention, the connecting portion is connected in the middle of the shoulder portion, and the shoulder portion extends between the connecting portion and the constricted portion. With this configuration, when the adjustment strip is adjusted, the shoulder portion receives a part of the adjustment strip, and coupled with the narrow width of the constriction portion, the adjustment strip enters the constriction portion. To prevent.

  In one embodiment of the present invention, the shoulder portion of the base portion of the first member has a protruding portion that protrudes in a direction in which the head portion protrudes from the base portion at a portion to which the connecting portion of the second member is connected. By connecting the connecting portion of the second member to the protruding portion that partially protrudes from the shoulder portion of the first member, the connecting portion, that is, the second member is difficult to move along the length direction of the shoulder portion. Therefore, it becomes easy to apply the adjustment strip to the buckle and adjust the length of the adjustment strip.

  In one embodiment of the present invention, the shoulder portion of the base portion of the first member has an expansion portion that restricts movement along the length direction of the shoulder portion of the connection portion of the second member. By providing such an extended portion, it is possible to prevent movement along the length direction of the connecting portion, that is, the shoulder portion of the second member. Therefore, it becomes easy to apply the adjustment strip to the buckle and adjust the length of the adjustment strip.

  According to another aspect of the present invention, the first member is provided with an annular first member made of a first metal wire, and a second member made of a second metal wire that is rotatably connected to the first member. Has a base defining a first opening through which the adjustment strip passes, and a head protruding from the base, the base having a bottom shaft portion, side portions extending in the protruding direction of the head on both sides, and both sides A connecting portion of the second member is connected to the shoulder portion, the shoulder portion extends inward from the connecting portion, and the head portion is continuous from the shoulder portion. There is provided a buckle having both side portions and a pressing portion extending in a direction approaching each other from both side portions on the distal end side of the head.

  In the present invention, since the shoulder portion of the base portion of the first member extends inward from the connecting portion of the second member, the adjustment strip does not easily enter the inside of the head portion.

  In one Embodiment of this invention, it has an edge part of the 1st metal wire in the said holding | suppressing part. By adjusting both ends of the annular first metal wire to the end with a slight gap at the holding part, the adjusting strip moves to one side of the top and bottom of the head while the adjusting strip is held by the holding part. Since this end exists when a force is applied in this way, the force is not transmitted to the other side. For this reason, the pressing of the adjustment strip can be performed more suitably.

  In the buckle according to the present invention, since the head portion of the base portion of the first member includes a constricted portion having a width interval narrower than the width of the first opening portion and having the narrowest width interval, the first opening portion and the second opening portion. The part which covers the head of the base of the 1st member in the adjustment strip passed through the part becomes difficult to enter the inside of the head. In the buckle according to another aspect of the present invention, the shoulder of the base portion of the first member extends inward from the connecting portion of the second member, so that the adjustment strip does not easily enter the inside of the head. Therefore, the length of the adjustment strip passed through the buckle can be smoothly performed, and the appearance of the adjustment strip is not impaired.

  Preferred embodiments of the present invention will be described below with reference to the drawings. 1 and 2 are a perspective view and a plan view of a buckle 1 according to an embodiment of the present invention. 3-5 is explanatory drawing showing the state which applies the buckle 1 to the connection strip 30 and the adjustment strip 31 which are a pair of strip pieces attached to the waist | hip | lumbar part of jeans as an example. The connecting strip 30 and the adjustment strip 31 are woven and knitted thin fabrics having the same width (length in the direction perpendicular to the longitudinal direction). The buckle 1 is a substantially convex annular first member 10 to which one end portion of the connecting strip 30 is fixedly connected, and is connected to the first member 10 so as to be rotatable, and the adjustment strip 31 is passed therethrough. It is comprised from the C-shaped or substantially U-shaped second member 20. The 1st and 2nd members 10 and 20 consist of metal wires, such as an aluminum alloy and a trunk alloy, as a 1st and 2nd metal wire, respectively. The first member 10 has a left opening that defines a first opening 13 with a vertical spacing slightly larger than the width of the connecting strip 30 (upper and lower and left and right are based on the paper surface 1 in FIGS. 2 and 4 unless otherwise defined). And a head portion 12 that protrudes rightward from the base portion 11 and that has a vertical interval (width interval) smaller than that of the base portion 11. The width interval between the heads 12 is narrower (smaller) than the width of the adjustment strip 31. The base portion 11 includes a bottom shaft portion 11a that extends straight up and down, and upper and lower portions that extend from the upper and lower ends of the bottom shaft portion 11a to the right, respectively, perpendicular to the bottom shaft portion 11a and shorter than the bottom shaft portion 11a. It has a side part 11b and upper and lower shoulder parts 11c that extend from the right ends of the upper and lower side parts 11b downward and upward to the boundary (constricted part 12c) with the head 12 respectively. The head portion 12 extends between the upper and lower side portions 12a extending rightward from the lower end of the upper shoulder portion 11c and the upper end of the lower shoulder portion 11c of the base portion 11, and the right end of the upper and lower side portions 12a. 20 and a pressing portion 12b that plays a role of pressing the adjustment strip 31 between the control strip 31 and the control strip 31. The upper and lower sides 12a of the head 12 are inclined so that the vertical interval gradually increases from the left to the right, and the left ends (boundaries with the base 11) of the upper and lower sides 12a are on both sides ( 12a, 42a), the narrowed portion 12c has the narrowest vertical interval (width interval). The vertical interval of the constricted portion 12 c is about 1/3 to 1/4 of the width of the adjustment strip 31, and also between the right ends of the upper and lower side portions 12 a having the largest vertical interval in the head 12. The width is about 1/2 to 1/3 of the width. Therefore, the adjustment strip 31 is unlikely to enter between the upper and lower side portions 12a of the head 12 during use. The pressing portion 12b is slightly curved so as to protrude rightward. The wire constituting the first member 10 is processed so that both ends thereof are close to or in contact with each other in the middle between the upper and lower portions of the pressing portion 12b to form a kind of seam 12d.

  The second member 20 protrudes upward and downward from a top portion 21 extending vertically to sandwich the adjustment strip 31 with the pressing portion 12b of the first member 10, and from above and below the top portion 21, respectively. And upper and lower legs 22 that are curved in a semicircular shape and extend leftward. The top portion 21 is slightly curved so as to protrude rightward in the same manner as the pressing portion 12b, but the curvature of the top portion 21 is slightly smaller than the curvature of the pressing portion 12b. A portion of the top portion 21 of the second member 20 corresponding to the pressing portion 12b of the first member 10 is a receiving portion 21a in which a wire having a circular cross section is flattened and slightly expanded left and right. The vertical width is larger than the vertical width of the pressing portion 12b. And the inside of the receiving part 21a is also curved. As a result, when the adjustment strip 31 is pressed by the pressing portion 12b, it becomes a resistance of the adjustment strip 31 that has passed through the second opening 23, and displacement of the adjustment strip 31 can be prevented. In addition, since the curvature of the pressing portion 12b and the receiving portion 21a is different and the curvature of the receiving portion 21a is smaller than the curvature of the pressing portion 12b, the pressing portion 12b is adjusted by concentrating the force on the portion near the center in the vertical direction. The strip 31 can be pressed. The surface of the receiving portion 21a facing the pressing portion 12b is roughened, whereby the frictional resistance against the adjustment strip 31 is increased. Each leg portion 22 is bent in a semicircular shape, and is connected to the left and right shoulder portions 11c of the base 11 of the first member 10 so as to be rotatable. Part 22b. The first member 10 is relatively rotatable with respect to the second member 20 around the shoulder portion 11c connected to the connecting portion 22b of the second member 20. Each connecting portion 22b is curled in a substantially C shape from below to above and from left to right based on the paper surface of FIGS. 3 and 5, and is wound around the shoulder portion 11c. A portion of each shoulder portion 11c corresponding to the connecting portion 22b is a protruding portion 11d protruding rightward. Thereby, it becomes difficult for the connecting portion 22b to come off from the protruding portion 11d, and the vertical movement along the shoulder portion 11c of the connecting portion 22b, that is, the vertical movement of the second member 20 relative to the first member 10 is restricted. In the second member 20, a second opening 23 is defined inside the top portion 21 and the curved portion 22 a of the upper and lower leg portions 22. Further, the shoulder portion 11c is a portion between the side portion 11b and the constricted portion 12c, and the connecting portion 22b is in the middle of the shoulder portion 11c (a position away from the side portion 11b and the constricted portion 12c). The vertical dimension of the metal wire which is connected and forms the connecting part 22b is smaller than the vertical dimension of the shoulder part 11c, and the shoulder part 11c is between the connecting part 22b and the constricted part 12c. When the adjustment strip 31 is adjusted, the adjustment strip 31 receives a part of the adjustment strip 31, and coupled with the narrow width of the narrow portion 12c, the adjustment strip 31 enters the narrow portion 12c. To prevent. The maximum vertical distance of the second opening 23 is slightly smaller than the vertical distance of the first opening 13 of the first member 10 and slightly larger than the width of the adjustment strip 31.

  Next, the use state of the buckle 1 will be described with reference to FIGS. The connection strip 30 and the adjustment strip 31 are fixed by sewing one end (not shown) (hereinafter referred to as “fixed end”) to the waist of jeans. The connecting strip 30 extends from the left fixed end to the right buckle 1, and the other end 30a extends to the first opening 13 in the base 11 of the first member 10 of the buckle 1 (based on FIG. 5). After being passed through, it is folded back to the left so as to wind the bottom shaft portion 11a and sewn to the connecting strip 30 near the bottom shaft portion 11a (see FIGS. 3 and 5). As a result, the other end 30A of the connecting strip 30 forms a ring around the bottom shaft portion 11a and is rotatably attached to the bottom shaft portion 11a. The adjustment strip 31 extends from the right fixed end to the left buckle 1, and the other end 31 a extends to the first opening 13 of the first member 10 of the buckle 1 (see FIG. 5). And then folded back to the right so as to cover the head 12 of the first member 10 and then into the second opening 23 of the second member 20 (based on FIGS. 3 and 5). (From top to bottom). Hereinafter, the other end 31a side portion of the adjustment strip 31 that has passed through the second opening 23 is referred to as an “adjustment strip passage portion 31A”. Thereafter, the adjustment strip passage portion 31A is bent to the right. Next, the first member 10 is rotated around the shoulder 11c connected to the connecting portion 22b of the second member 20 (counterclockwise direction based on FIG. 3), and the head 12 of the first member 10 is pressed. The part 12 b is pressed against the receiving part 21 a of the top part 21 of the second member 20. As a result, as shown in FIG. 5, the adjustment strip 31 is sandwiched between the pressing portion 12b and the receiving portion 21a, and is curved so as to draw a substantially S-shape before and after the sandwiched portion. Therefore, the adjustment strip passage portion 31A does not come back to the second opening 23 as long as the pressing portion 12b and the receiving portion 21a are substantially closed with the adjustment strip 31 interposed therebetween. As shown in FIG. 5, the adjustment strip 31 passes through the first opening 13 between the connection strip 30 connected to the bottom shaft portion 11 a and the shoulder portion 11 c. And it is preferable that the width | variety (dimension of an up-down direction) of this connection strip 30 is larger than the width | variety between a pair of connection parts 22b so that the part which a pair of connection parts 22b of the 2nd member 20 connects may be covered. . When the length of the adjustment strip passage portion 31A is increased, the fixed end portion of the connecting strip 30 and the fixed end portion of the adjustment strip 31 approach each other, and the gap between the fixed end portions is narrowed. Tighten. On the other hand, when the length of the adjustment strip passage portion 31A is reduced, the interval between the fixed ends of the connection strip 30 and the adjustment strip 31 is widened, and the waist of the jeans is partially loosened. In a state where the length of the adjustment strip passage portion 31A is increased and the waist of the jeans is tightened, the adjustment strip 31 is pulled toward the fixed end (the connecting strip 30 is also pulled toward the fixed end). Accordingly, a portion of the adjustment strip 31 (hereinafter referred to as “adjustment strip head corresponding portion”) 31B that covers the head 12 of the first member 10 (from above based on FIG. 5) is the head of the first member 10. 12 is urged toward the second member 20, whereby the pressing portion 12 b is pressed against the receiving portion 21 a and acts to tighten the adjustment strip 31. Referring to FIG. 4, the head 12 of the first member 10 of the buckle 1 has the narrowest vertical distance at the constricted portion 12 c at the boundary with the base 11, and thus the adjustment strip head corresponding portion 31 B described above is provided. Even when the head 12 of the first member 10 is urged toward the second member 20, the adjustment strip head corresponding portion 31 </ b> B hardly enters the inside of the head 12.

  In addition to the method shown in FIG. 3, there is a method shown in FIG. 6 for passing the adjustment strip 31 through the buckle 1. That is, the other end 31 a of the adjustment strip 31 is passed through the second opening 23 of the second member 20 of the buckle 1 (from the bottom to the top based on FIG. 6), and then the head 12 of the first member 10 is passed. It is bent to the left so as to cover, passed through the first opening 13 of the first member 10 (from top to bottom based on FIG. 6), and then bent to the left. In this case, when the length of the other end 31a side portion of the adjustment strip 31 that has passed through the first opening 13 is increased, the waist of the jeans is partially tightened, and when the length is reduced, the adjustment strip 31 is loosened. Even in the manner of passing the adjustment strip 31 of FIG. 6, the adjustment strip head corresponding portion 31B that covers the head 12 of the first member 10 does not easily enter the inside of the head 12 including the constricted portion 12c.

  FIG. 7 is a plan view showing a buckle 2 which is a modification of the buckle 1, and portions substantially common to the buckle 1 are denoted by the same reference numerals as the buckle 1. Buckle 2 differs from buckle 1 in the following points. That is, in the shoulder portion 11c of the base portion 11 of the first member 10, there is no protruding portion 11d in the portion connected to the connecting portion 22b of the leg portion 22 of the second member 20, and instead the upper and lower connecting portions 22b On the inner side in the direction, there is provided an extended portion 11e in which the wire constituting the shoulder portion 11c is partially crushed and flattened. Since the connecting portion 22b cannot pass over the extended portion 11e, the vertical movement along the shoulder portion 11c of the connecting portion 22b is restricted. FIG. 8 is a plan view showing a first member 10 a which is a modification of the first member 10 of the buckle 1. In the first member 10a, the pressing portion 12e corresponding to the pressing portion 12b of the first member 10 is flattened, and the first member 10a is substantially the same as the first member 10 except for the pressing portion 12e. The same reference numerals as those in FIG. The pressing portion 12e is formed so that the flatly expanded surface faces the rough surface of the receiving portion 21a of the second member 20 substantially in parallel. FIG. 9 is a plan view showing a first member 10 b which is another modified example of the first member 10. Since the first member 10b has a pressing portion 12f corresponding to the pressing portion 12b of the first member 10 formed in a straight line and is substantially the same as the first member 10 except for this point, the same reference as the first member 10 is made. It is numbered. FIG. 10 is a plan view showing a first member 10 c which is still another modified example of the first member 10. The first member 10c is bent in a V shape so that the pressing portion 12g corresponding to the pressing portion 12b of the first member 10 is recessed leftward, whereby the pressing portion 12b and the upper and lower side portions 12a have an acute angle. Is formed. Other than the pressing portion 12e, the first member 10 is substantially the same as the first member 10, and therefore, the same reference numerals as those of the first member 10 are given. The holding part 12b is easy to fix the adjustment strip 31 to the receiving part 21a.

  FIG. 11 is a plan view showing a buckle 3 which is another modification of the buckle 1. The buckle 3 includes a first member 40 and a second member 50 that is rotatably connected to the first member 40. The first member 40 includes a rectangular base 41 and a circular head 42 protruding rightward from the base 41, and a first opening 43 is defined inside the base 41. A constricted portion 42c having the narrowest vertical distance exists at the boundary of the head portion 42 with the base portion 41, and an arc-shaped pressing portion 42b is provided on the right side of the head portion 42.
