Description

  The present invention relates to a shoe. More specifically, the present invention relates to an improvement in the structure of a shoe with a shoelace.

  In a shoe, particularly a mountain shoe, in order to improve the fit to the foot, many places where the shoelace is folded back may be arranged (see, for example, Patent Document 1).

JP 2002-282005 A

  However, such shoes usually have a high fit, but are usually difficult to perform a shoelace tightening or loosening operation.

  Then, an object of this invention is to provide the shoes which are easy to tighten a shoelace to a shoe tip and are easy to loosen the tightened shoelace.

  In order to solve this problem, the present inventor has made various studies. If there are many straps (the part where the upper and shoelaces are joined and where the shoelaces are folded back) as in conventional mountain shoes, the way of passing the shoelaces through the straps is simply changed. It is difficult to improve the ease of tightening and loosening the shoelace without impairing the fit. Further, if the number of threading is simply reduced, the ease of tightening and loosening of the shoelace is improved, but a high fit cannot be obtained. Based on these points, the present inventor who has made various studies focusing on the frictional resistance when tightening or loosening the shoelace has made appropriate the way of passing the shoelace and the angle of passing the shoelace. As a result, it has been found that the frictional resistance is reduced, the shoelace can be easily tightened up to the shoe tip, and can be easily loosened when the shoe is taken off.

  The present invention is based on such knowledge, and in a shoe including a lace-back portion formed on the upper and a shoe lace folded back at the lace-back portion, there are a plurality of connecting portions for connecting the upper and the shoe lace. It is characterized in that a string turn-back portion is formed as a set.

  In general, a conventional shoe has a structure in which shoelaces are sequentially folded by a single stringer repeatedly arranged on the left and right. In this case, it means that there is only a single connecting portion for connecting the upper and the shoelace, and the shoelace has a V-shaped shape or a channel shape in the single connecting portion, and the folding angle becomes steep. For this reason, the frictional resistance when tightening or loosening the shoelace tends to increase. On the other hand, in the shoe according to the present invention, since the fold-back portion is formed as a set of a plurality of connecting portions for connecting the upper and the shoelace, the fold-back portion is wide, Moreover, the number of fold-back portions of the shoe as a whole is reduced. For this reason, the foldback angle of the shoelace becomes gentle, and the frictional resistance when the shoelace is tightened or loosened is reduced, the shoelace is easily tightened, and the tightened shoelace is easily loosened.

  Moreover, in the shoe according to the present invention, it is not necessary to reduce the number of coupling portions for coupling the upper and the shoelace as compared with the conventional shoe. For this reason, a high fit at the time of wearing shoes is not spoiled.

  In such a shoe, it is preferable that the coupling portion is formed by a plurality of stringers spaced apart from each other.

  The stringing is, for example, attached to the upper to form an annular or tubular string guide.

  Moreover, in such a shoe, it is preferable that the coupling portion is inclined in a direction in which the foldback angle of the shoelace is moderated.

  Furthermore, it is also preferable that a plurality of sets of coupling portions are inclined in a direction in which they are close to each other.

  It is also preferable that a plurality of sets of coupling portions are arranged in a square shape.

  Moreover, it is also preferable that the coupling portion is provided with a string guide that moderates the foldback angle of the shoelace.

  Furthermore, it is preferable that the shoelaces are sequentially passed through a plurality of laces forming a lace-back portion, and further passed sequentially through a plurality of laces forming another lace-back portion.

  According to the present invention, the shoelace can be easily tightened up to the shoe tip, and the tightened shoelace can be easily loosened.

1 is an overall view showing an example of a shoe to which the present invention is applied. It is an enlarged view of the upper part of the shoe shown in FIG. It is an enlarged view of the string thread (joining part) in other embodiments of the present invention. It is a reference figure which shows the conventional shoes as a comparative example.

  Hereinafter, the configuration of the present invention will be described in detail based on an example of an embodiment shown in the drawings.

  1 to 2 show an embodiment of a shoe according to the present invention. Hereinafter, as an example, a shoe suitable for mountain or exercise will be described as an example.

  The shoe 1 includes a lace return portion 3 formed on the upper 2 and a shoe lace 4 that is turned back at the lace return portion 3, and the shoe 1 according to the present embodiment further includes a lace 51. Tan 5 is provided.

  The upper 2 is provided with a string thread 31 for allowing the shoelace 4 to pass therethrough. A specific example of the string thread 31 is not particularly limited. For example, in this embodiment, a belt-shaped member (tape) is folded halfway, and both ends thereof are sewn into the upper 2 and attached. A through 31 is provided to guide the shoelace 4. The lace 31 forms a connecting portion for connecting the upper 2 and the shoelace 4.

  Here, in the present embodiment, two pairs of the string passages (joining portions) 31 that are spaced apart from each other are taken as one set, and one set of the string return portions 3 is formed by the one set of string passages 31. In this case, the string folding portion 3 is wider than the conventional one, that is, the width of one string folding portion 3 in the front-rear direction of the shoe is wider than the conventional one, and is accordingly wide. As a result, there are few fold-back portions of the shoe as a whole, and the connecting portions are dispersed in the front-rear direction (see FIGS. 1 and 4). For this reason, the bending state of the shoelace 4 in the vicinity of the threading 31 is more gradual than before, and the folding angle of the shoelace 4 is moderate, so that the frictional resistance when tightening or loosening the shoelace 4 is increased. It is getting smaller.

  The shoelace 4 is passed through the strap 31 as described above as shown in the figure. That is, in the shoe 1 of the present embodiment, the shoelace 4 is sequentially passed through a plurality of string loops 31 forming one string folding section 3 and further a plurality of string loops 31 forming another string folding section 3. (See FIG. 2 etc.).

  Further, the string thread 31 is inclined in a direction that makes the fold angle of the shoelace 4 gentle. For example, in the present embodiment in which one string turn-back portion 3 is formed as a pair of two string passages 31 that are separated from each other as described above, each string passage 31 is inclined to the upper 2 in a state of leaning toward each other. It is attached (see FIG. 2). In such a case, the shoelace 4 in the strap turn-up portion 3 is curved in a circular arc shape or a shape approximate thereto, and the turn-back angle becomes gentle as a whole.

  Further, in the present embodiment, a plurality of string loops 31 forming one string turn-back portion 3 are arranged so as to have a square shape (a divergent shape) with respect to the shoe body 2. When the laces 31 that function as fulcrums when the shoelace 4 is tightened are arranged in a C shape in this way, the angle that reduces the frictional resistance of the shoelace 4 and the angle that becomes the fulcrum on the shoe body 2 side Can be effectively realized. Therefore, in the shoe 1 of this embodiment, the shoelace 4 can be tightened more efficiently.

  Note that it is not necessary for all the string loops 31 to form the string folding portion 3 in pairs. For example, among the plurality of string loops 31, the one arranged near the toe of the upper 2 may be a place where the movement of the shoelace 4 is small during the string tightening operation or the loosening operation. It may be formed (see FIGS. 1 and 2).

  As described above, the shoe 1 according to the present embodiment is easy to tighten the shoelace 4 to the shoe tip and easily loosen the tightened shoelace 4. That is, in the shoe 1 of the present embodiment, the fold-back portion 3 is wide, and the number of fold-back portions of the shoe as a whole is small. The frictional resistance at the time of loosening or loosening is small, and the shoelace 4 is easily tightened or loosened.

  Further, when the shoe 1 as in the present embodiment is configured, it is possible to easily tighten or loosen the shoelace 4 without reducing the number of string passages (joining portions) 31 compared to the conventional shoes. If the number of shoe threaders 31 is simply reduced, it is possible to easily tighten or loosen the shoelace 4, but there is a risk that the high fit when wearing the shoes will be impaired. . In this respect, in the present embodiment, since it is not necessary to change the number of laces 31 from the conventional shoe, the fulcrum when the shoe 1 is tightened with the shoelace 4 does not change. In short, according to the shoe 1 of the present embodiment, the shoelace 4 can be tightened smoothly to the shoe tip by appropriately adjusting the angle of the shoelace 4 and the stringing 31 without impairing the fit. Easy to loosen when taking off. Therefore, the shoe 1 of the present embodiment has an advantage that it can be manufactured by slightly changing the basic structure and manufacturing process of an existing shoe.

  Moreover, even if the way of passing the shoelaces through the laces (the pass through) is simply changed while the structure of the conventional shoes remains unchanged, the fold-back angle of the shoelaces 4 will be gentle for each shoelace. Is not configured and arranged, it is difficult to improve the ease of tightening and loosening the shoelace without impairing the fit. On the other hand, according to the present embodiment, it is possible to improve the ease of tightening and loosening the shoelace 4 without damaging the fit, by slightly changing the basic structure or the like of the existing shoes.

  In addition, while the conventional shoes as described above may require a ring, a cord lock, etc., according to this embodiment, a mechanism for reducing frictional resistance while following the conventional tying method is constructed. can do.

  The above-described embodiment is an example of a preferred embodiment of the present invention, but is not limited thereto, and various modifications can be made without departing from the scope of the present invention. For example, in the above-described embodiment, one string folding portion 3 is formed by combining two string loops 31 as a set, but this is only a representative form, and one string folding section is formed by three or more string loops 31. 3 may be formed.

  Further, in the above-described embodiment, the plurality of substantially the same string passages 31 that have different attachment angles to the upper 2 are exemplified, but the shape, thickness, length, pattern, color, etc. of each string passage 31 are exemplified. Furthermore, the material, material, surface quality, and the like may be appropriately changed. For example, the string thread 31 may be a hook-shaped string guide in addition to the loop-shaped band-shaped member (tape) as described above for allowing the shoelace 4 to be inserted, or a curved resin part. Or a metal eyelet (see FIG. 3).

  In the above-described embodiment, the coupling portion that couples the upper 2 and the shoelace 4 is exemplified by the string thread 31. However, the coupling portion moderates the folding angle of the shoelace 4. It is also preferable to provide a string guide 3a. For example, when the lace 31 is a curved resin part as described above, the curved portion or both ends of the lace 31 that gently loosens the shoelace 4 function as the lace guide 3a (see FIG. 3). ).

  In addition, even if it is a case where the string folding | turning part 3 is formed with the single string thread | sled 31 or looks like it, the coupling | bond part (site | part which couple | bonds the upper 2 and the shoelace 4) as used in this specification A case where the number is substantially plural is included in one embodiment of the present invention. For example, in the case where the angle of the shoelace 4 is gently changed at one end of the single elongate string 31 and the shoelace 4 is gradually changed to a different angle at the other end, the upper 2 and the shoe It can be handled that there are substantially a plurality of coupling portions for coupling the string 4 and these form the string folding portion 3.

  The present invention is suitable for application to any shoe that tightens or loosens a shoelace, such as mountain shoes or athletic shoes.
