Below, the same code | symbol is attached | subjected to the same element in all the drawings, and the overlapping description is abbreviate | omitted. In the description in the text, the symbols described before are used as necessary.

  FIG. 1 is a view showing a flat string winding fastener 10 according to a first embodiment of the present invention. FIG. 2 is a view showing a state in which the flat string 2 is wound around the flat string winding fastener 10 and fastened. FIG. 3 is a view showing a flat string winding fastener 20 according to the second embodiment of the present invention. FIG. 4 is a view showing a flat string winding fastener 30 according to the third embodiment of the present invention.

  Initially, the flat string winding fastener 10 which is 1st embodiment of this invention is demonstrated using FIG. 1, FIG. The flat string winding fastener 10 is an instrument for winding and fastening a flat string 2 used for a backpack or the like. The flat string 2 is a belt-like webbing containing fibers such as cotton, and is used for a part for adjusting the length of the shoulder of the backpack.

  Although the size of the flat cord 2 is various, here, as an example, the width of the flat cord 2 is 25 mm and the thickness of the flat cord 2 is 2 mm. However, of course, this size can be changed as appropriate.

  The flat string winding fastener 10 includes a winding core portion 12, two restricting portions 14 a and 14 b, and an entrance / exit portion 16. Although the winding core part 12, the two restricting parts 14a and 14b, and the entrance / exit part 16 may be formed of separate members, here, description will be made assuming that they are integrally formed of the same material.

  As shown in the front view shown in FIG. 1 (a), the flat string winding fastener 10 has a quadrangular outer shape. As an example of the size of this quadrangular shape, the vertical (longitudinal direction) length is 40 mm. It is assumed that the horizontal (short direction) length is set to 31 mm.

  The winding core part 12, the two restricting parts 14a and 14b, and the entrance / exit part 16 are preferably formed using a resin such as plastic having a material having appropriate flexibility and strength. For example, it can also be formed using a rubber member or a metal member.

  The winding core 12 extends in the width direction of the flat cord 2 so as to be wound from the end 2a of the flat cord 2, and has a rod shape having a flat portion. The winding core portion 12 has two rod portions 12 a and 12 b extending in the width direction of the flat cord 2.

  The two rod portions 12a and 12b are provided with a predetermined gap therebetween, whereby the space region 13 is formed. Of the two rod portions 12a and 12b, the outer rod portion 12b located on the opposite side to the entrance / exit portion 16 is formed with a slit portion 12c provided so that the flat string 2 can be taken in and out of the space region 13.

  The two rod portions 12a, 12b have a length in the longitudinal direction set to 25 mm, which matches the width of the flat cord 2, and a length in the short direction is preferably set to 6 mm. The thickness of the two rod portions 12a and 12b is preferably set to 3 mm.

  The predetermined gap between the two rod portions 12a and 12b is set to 6 mm. For this reason, the size of the space region 13 is 6 mm × 25 mm.

  The width of the slit portion 12c formed in the bar portion 12b is preferably set to a width equal to or smaller than the width of the flat cord 2 and equal to or larger than the thickness of the flat cord 2. The slit portion 12c is set to have a distance of 5 mm from the restricting portion 14a and a distance from the restricting portion 14b to 18 mm.

  The two restricting portions 14a and 14b have rod shapes extending from both ends of the winding core portion 12 and having flat portions. The movement of the flat cord 2 in the width direction when the flat cord 2 is wound around the winding core 12 is restricted.

  The length in the longitudinal direction of the two restricting portions 14a and 14b is 40 mm, and the length in the short direction is 3 mm. The thickness of the two restricting portions 14a and 14b is 3 mm. The distance between the two restricting portions 14a and 14b is 25 mm.

  The entrance / exit part 16 is provided between the two restricting parts 14. When the flat cord 2 is wound around the winding core portion 12, the entrance / exit portion 16 can take the flat cord 2 into and out of a space region 15 formed between the winding core portion 12 and the two regulating portions 14. It has the notch part 12 provided so.

  As for the entrance / exit part 16, the length of the longitudinal direction is set to 25 mm according to the width | variety of the flat string 2, and it is preferable to set the length of a transversal direction to 6 mm. Moreover, it is suitable to set the thickness of the entrance / exit part 16 to 3 mm.

  The width of the notch portion 16a formed in the entrance / exit portion 16 is preferably set to a width equal to or less than the width of the flat cord 2 and equal to or greater than the thickness of the flat cord 2. By setting in such a range, it can be inserted when twisting the flat cord 2 and entering the space area 15 from the entrance / exit 16, but when the twist is returned in the space area 15, Since the width of the entrance / exit portion 16 is smaller than the width of the flat cord 2, the flat cord 2 can be prevented from exiting the entrance / exit portion 16. The notch 16 is set to have a distance of 5 mm from the restricting portion 14b and set to a distance of 18 mm from the restricting portion 14a.

  Then, the effect | action of the flat string winding fastener 10 of the said structure is demonstrated using FIG. 1, FIG. For example, in a backpack carried by a person (user), flat cords 2 are used in various places. However, flat cords 2 for adjusting the length of a shoulder strap may be troubled because the remaining flat cords 2 are too long.

  For example, when the backpack is placed on the floor in a train, if the extra flat cord 2 spreads outside, it may be inconvenient to be stepped on another person's shoes or get dirty. It is desirable to summarize.

  Therefore, the user takes out the flat string winding fastener 10, passes the end 2a of the flat string 2 from the lower side to the upper side of the space area 15 as shown in FIG. As shown in FIG. 2B, the second end 2a is passed from the upper side to the lower side of the space region 13 so that the end 2a of the flat cord 2 is engaged with the lower part of the bar 12b.

  Although the boundary 2b is shown on the opposite side of the end 2a of the flat cord 2, the flat cord 2 (not shown) is further extended from the boundary 2b and connected to the shoulder, so that the flat cord 2 is connected to the two rod portions 12a. In order to wind around the winding core 12 constituted by 12b, as shown in FIG. 2 (c), the flat cord 2 is twisted and the thickness direction of the flat cord 2 and the width of the notch 16a are twisted. The state is such that the flat cord 2 stands up on the notch 16a with the directions being matched.

  Thereafter, the flat string 2 is passed from above the notch 16a to below and then twisted back, and wound around the winding core 12 via the space region 15 as shown in FIG. 2 (d). . Since the width of the notch 16a is set to be equal to or smaller than the width of the flat cord 2 and larger than the thickness of the flat cord 2, when the flat cord 2 is twisted and inserted into the space region 15 from the entrance / exit portion 16 Although it can be inserted, it is possible to prevent the flat cord 2 from exiting the entrance / exit 16 when the twist is returned in the space region 15.

  Thereafter, the procedure shown in FIGS. 2 (b) to 2 (d) is repeated and wound around the winding core 12 a predetermined number of times, and then the flat cord 2 is placed below the entrance / exit 16 as shown in FIG. Engage.

  In FIG. 2, in order to make the relationship between the flat string 2 and the flat string winding fastener 10 easy to understand, the flat string 2 is described as a transparent string without the thickness of the flat string 2. Therefore, after winding, the state is as shown in FIG.

  In the state shown in FIG. 1C, the flat cord 2 is wound a predetermined number of times across the two rod portions 12 a and 12 b, and the remaining flat cord 2 is engaged with the lower portion of the entrance / exit portion 16. In this state, the film is further extended through the boundary portion 2b and connected to the shoulder.

  As described above, the winding state is maintained while the movement in the width direction of the flat cord 2 is regulated by the regulating portions 14a and 14b by being wound a predetermined number of times. Even if a force acts in the direction in which the winding is unwound, the movement of the flat cord 2 is restricted by the entrance / exit portion 16, so that the flat cord 2 can be prevented from being unwound. Further, since the rod portions 12a and 12b have flat portions, there is an effect that the flat cord 2 can be easily wound.

  It is possible to fasten the flat string 2 without using a rubber band, a hook-and-loop fastener, or the like, simply by winding the remaining flat string 2 so as to be in the state shown in FIG. Since this is possible, there is an advantage that the remaining flat cord 2 can be stored in a clean state. Accordingly, even if a rucksack is placed on the floor in the train, the remainder of the flat cord 2 does not spread outward, so that it can be prevented from being stepped on or dirty by others.

  Further, since the flat string winding fastener 10 is formed with the slit portion 12c, when the flat string 2 is to be shifted from the state shown in FIG. 2A to the state shown in FIG. By matching the width direction of the end portion 2a with the width direction of the slit portion 12c, there is an advantage that the space portion 13 can be easily inserted.

  In addition, although the flat string winding fastener 10 provides the space area | region 13 between the two rod parts 12a and 12b, and engages the edge part of the flat string 2 with the lower part of the rod part 12b, the space area | region 13 is preferable. The flat string 2 may be wound around the two rod portions 12a and 12b formed as one flat rod portion.

  Next, the flat string winding fastener 20 which is 2nd embodiment of this invention is demonstrated. The flat string winding fastener 20 is an instrument for winding and fastening the flat string 2 used for a backpack etc. similarly to the flat string winding fastener 10.

  The flat string winding fastener 20 includes a winding core portion 22 having two rod portions 22a and 22b, two regulating portions 24a and 24b, and an entrance / exit portion 26. The only difference is the positional relationship between the notch portion 26a and the slit portion 22c, and the other configurations are the same.

  The notch portion 26a and the slit portion 22c are formed at a distance of 11.5 mm from the rod portions 24a and 24b, that is, formed in the middle of the entrance / exit portion 26 and the rod portion 12b.

  The flat string winding fastener 20 is different from the flat string winding fastener 10 in the positions of the notch portion 26a and the slit portion 22c. Due to the difference in position, only the positional relationship when twisting the flat string 2 into the space regions 23 and 25 is changed, and the other configurations are the same, so the same effect as the flat string winding fastener 10 is obtained. .

  Next, a flat string winding fastener 30 according to a third embodiment of the present invention will be described. The flat cord winding fastener 30 is an instrument for winding and fastening the flat cord 2 used for a backpack or the like, similarly to the flat cord winding fastener 20.

  The flat string winding fastener 30 includes a winding core portion 32 having two rod portions 32a and 32b, two restriction portions 34a and 34b, and an entrance / exit portion 36. The only difference is the width of the notch 36a and the slit 32c, and the other configurations are the same.

  The notch portion 36a and the slit portion 32c are formed at a distance of 7 mm from the rod portions 34a and 34b. That is, the width of the notch portion 36a and the slit portion 32c is 11 mm.

  In the flat string winding fastener 30, the width of the cutout portion 36a and the slit portion 32c is larger than the cutout portion 26a and the slit portion 22c of the flat string winding fastener 20. By increasing the widths of the notch portion 36a and the slit portion 32c, there is an advantage that the flat string 2 can be easily twisted into the space regions 33 and 35. Moreover, since the other structure is the same, there exists an effect similar to the flat string winding fastener 20. FIG.
