Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a footwear fixing mechanism for fastening an upper to a footwear by fastening an upper with a fastening belt.

  In general, in footwear having a sole and an upper attached to the upper part thereof, for example, a shoe lace is used to fasten the upper where the instep is located to fix the foot. It must be done, and it becomes complicated when the number of times of attachment and detachment is large. In this case, a foot-fixing mechanism for footwear that can easily attach and detach the foot and tighten the instep to fix the foot in the footwear has been known.

  As an example of this, there is a method of fastening a shoe upper in which a fastening belt is passed through a plurality of rings in a zigzag manner, and the belt is fastened and relaxed with one touch to detach the foot. Reference 1).

JP-A-11-32810

  However, in the conventional method, although the foot can be easily attached / detached with one touch, the belt is folded back in a zigzag shape. There was a problem that a relatively large force was required for fastening.

  In addition, since the belt is folded in a zigzag shape, the space where the belt is exposed on the upper surface of the upper becomes large, and the feet are easily caught, which is not preferable in terms of safety.

  Also, in working shoes such as safety socks and underground socks having a trunk extending above the upper cover to cover the calf, for example, underground socks have metal hooks for fixing feet. In some cases, it is complicated to engage and disengage a plurality of small hooks each time a foot is attached or detached. For this reason, there has been a demand for a foot fixing mechanism for working footwear that can easily attach and detach the foot, and is hard to catch on the foot and can secure a safety surface.

  SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems, and enables the foot to be easily attached and detached, and can be fixed with a small force, and the space for exposing the upper surface of the belt is reduced, which is also useful for work. The purpose is to provide.

  In order to achieve the above object, a foot fixing mechanism for footwear according to one configuration of the present invention is a foot fixing mechanism that is provided on an instep and fixes the foot in the footwear by fastening the instep with a fastening belt. A first ring and a second ring which are arranged to face each other in a linear direction and pass the belt; a root portion of the belt which extends through the first ring in the linear direction; and a second ring. A folded portion that passes through and overlaps the root portion in a linear direction, and a locking portion that is disposed on a linear extension of the root portion and the folded portion and locks a belt tip, wherein the folded portion is provided at the root portion. Are overlapped in the linear direction, the upper cover is narrowed in the linear direction by the pulling force of the belt via the first ring and the second ring and tightened, and in the tightened state, the tip of the belt engages with the locking portion. The foot is stopped and the foot is fixed in the footwear.

  According to this configuration, in a state where the folded portion overlaps the base portion of the belt in the linear direction, the upper is tightened, and then the belt is attached to the locking portion arranged on the linear extension of the base portion and the folded portion. Since the tip is locked and the foot is fixed in the footwear, it is easy to apply force in a straight line direction, and the instep can be tightened with a slight force to securely fix the foot in the footwear. Further, since the root portion and the folded portion of the belt overlap, the space where the belt is exposed on the upper surface of the instep can be reduced. As a result, the foot can be easily attached and detached, and can be fixed with a small force, so that the exposed space of the belt on the upper surface of the instep can be reduced and the foot can be hardly caught.

  In the present invention, it is preferable that the second ring of the foot fixing mechanism moves in the linear direction with the tightening of the belt. Further, at the folded portion, the belt is pulled in the linear direction toward the locking portion via the second ring, so that at least the belt length of the folded portion is shortened and the upper is tightened. preferable. In this case, since the second ring acts as a kind of moving pulley, the upper can be tightened with a lighter force.

  Preferably, the support member for the first ring includes a ring elastic member for expanding and contracting the first ring in the linear direction. Therefore, after the foot is firmly fixed in the footwear, the belt follows the bending movement of the foot due to walking due to the elastic force of the ring elastic, so that the movement can be prevented.

  Preferably, a lower fixing portion for fixing the leg by tightening the lower belt is provided in at least a lower position of the upper position and the lower position for assisting the leg fixing mechanism. In this case, the foot can be more firmly fixed in the footwear.

  A foot fixing mechanism for working footwear according to another configuration of the present invention has a body extending above the instep portion, and the foot fixing mechanism mainly fixes the instep portion. In order to assist the foot fixing mechanism, an upper fixing part for fixing the foot by tightening the upper belt is provided on at least the upper part of the upper part and the lower part of the body part. Here, the instep portion refers to a portion including the instep and the periphery of the ankle slightly above the instep. According to this configuration, the instep portion is fixed, and the torso portion is tightened by the upper fixing portion, so that the entire foot can be firmly fixed in the work shoes. Also, since the root portion and the folded portion of the belt overlap, the exposed portion of the belt is reduced, which is also preferable from the viewpoint of safety.

  The present invention relates to a locking portion arranged on a linear extension of the root portion and the folded portion after the folded portion of the foot is tightened in a state where the folded portion overlaps the root portion of the belt in the linear direction. Since the tip of the belt is locked and the foot is fixed in the footwear, the upper can be tightened with a slight linear force to securely fix the foot in the footwear. Further, since the root portion and the folded portion of the belt overlap, the space where the belt is exposed on the upper surface of the instep can be reduced.

It is a perspective view showing other examples of a foot fixing mechanism. It is a perspective view showing the foot fixing mechanism of footwear concerning a 2nd embodiment.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing a foot fixing mechanism 7 of a working shoe 1 such as a basement tabi according to a first embodiment of the present invention, and FIGS. 2A and 2B are side views thereof. As shown in FIG. 1, the work footwear 1 includes a sole 4 such as a rubber sole, an upper 3 attached to the upper part thereof, and a cover extending from the upper 3 to cover from an ankle to a calf. It has a trunk 5. This work footwear (basement tabi) 1 is not provided with a small hook made of metal, unlike the related art. The front surface of the torso portion 5 is vertically split and has an opening, and a widening member 6 is provided at the opening portion, so that the area of the wearing mouth can be increased and the foot can be easily inserted. After the foot is inserted, the upper 3 is tightened in a state where the widening member 6 is folded in the trunk 5.

  The work footwear (baseball tabi) 1 is different from the conventional one in that a metal small hook (kohaze) for fixing the foot is not provided. Is fixed. In this example, the part of the instep 3 located on the instep part 8 around the ankle, which is located slightly above the instep, is tightened.

  The foot fixing mechanism 7 includes a first ring 15 and a second ring 16 that are arranged to face each other in the substantially linear direction L and pass the belt 10, and a root of the belt 10 that extends through the first ring 15 in the linear direction L And a folded portion 12 that passes through the second ring 16 and overlaps the root portion 11 so as to cover the root portion 11, and is disposed on an extension of the root portion 11 and the folded portion 12 in the linear direction L to extend the tip of the belt 10. And a locking portion 13 for locking the lock.

  In this example, with the folded portion 12 overlapping the root portion 11 in a substantially horizontal linear direction L, the upper 3 is moved in the linear direction L by the pulling force of the belt 10 via the first ring 15 and the second ring 16. It is squeezed and tightened. At this time, the rear end of the folded portion 12 becomes the first ring 15. In this tightened state, the tip of the belt is locked by the locking portion 13 extending in the linear direction L, and the foot is fixed in the footwear. The locking portion 13 is, for example, a hook-and-loop fastener having a pair of loop-shaped surfaces and a hook-shaped surface.

  The locking portion 13 is not limited to the above-described hook-and-loop fastener, but may be a belt stopper mechanism as shown in FIG. This belt stopper mechanism includes a fixed portion 35 having a through hole 36 and a movable portion 31 that can move up and down in the fixed portion 35. The movable part 31 has a push button 33 with a through hole 32 and a spring 34. When the push button 19 is pressed, the through holes 32 and 36 communicate in a straight line, and the belt 10 can be inserted. When the push button 19 is released, the belt 10 is bent and locked between the through holes 32 and 36.

  In this example, as shown in FIG. 2 (B), the support portion 18 supported by the ring elastic member 17 in which the first ring 15 expands and contracts in the linear direction L is provided on the outer side of the upper 3 (left side as viewed). It is sewn and fixed. As shown in FIG. 1, the base end 10 c of the belt 10 is sewn to the outside (the right side as viewed) of the upper 3, is branched into two first and second branch belts 10 a and 10 b, and has a first ring 15. The base 11 is formed by the first branch belt 10a passed through the base. Then, it is folded back by the first ring 15 and fixed to the second ring 16 to form the folded back portion 12. After the second branch belt 10b is passed through the second ring 16 and folded, the second branch belt 10b is locked by the locking portion 13 as shown in FIG.

  As shown in FIGS. 2A and 2B, the first ring 15 and the second ring 16 are placed in a state in which the folded portion 12 overlaps the root portion 11 in the substantially linear direction L and the root portion 11 is hidden by the folded portion 12. The upper 3 is pulled down in the linear direction L by the pulling force of the belt 10 and tightened, and the tip of the belt is locked by the locking portion 13 on the straight line L extension, so that the foot is fixed in the footwear.

  As shown in FIG. 1, the second ring 16 of the foot fixing mechanism 7 moves in the linear direction L (rightward in the figure) together with the tightening of the upper 3 by the pulling force of the belt 10 and acts as a kind of moving pulley. At the same time, the first ring 15 and the outer shell (the left side in the figure) are pulled by the pulling force of the belt 10 and drawn toward the second ring 16 (the right side in the figure). Acts as a pulley. Since both the first ring 15 and the second ring 16 correspond to a kind of moving pulley, the pulling force becomes a light load of 1/4 of that in the case where both are fixed pulleys. The belt 10 is drawn down in the linear direction L via the first ring 15 and the second ring 16, so that the length of the folded portion 12 is shortened and the upper 3 is fastened. In addition, since the first ring 15 has the elastic member 17 for the ring, after the foot is firmly fixed in the footwear 1, the elastic force of the elastic member 17 for the ring causes the leg to bend when walking. The belt 10 can follow, so that the bending movement is not hindered.

  Therefore, compared to the conventional zigzag shape, the foot fixing mechanism 7 easily applies force in the linear direction L, tightens the upper cover 3 with a slight force, and further reduces the foot force by a kind of moving pulley. Can be firmly fixed in the footwear. Further, since the folded portion 12 overlaps the root portion 11 of the belt 10 in the linear direction L, the space where the belt 10 is exposed on the surface of the upper 3 can be made as small as possible, and the safety is enhanced.

  Further, as shown in FIGS. 2A and 2B, an upper fixing portion 22 that tightens the torso 5 with an upper belt 21 is provided on the torso 5 at an upper position for assisting the foot fixing mechanism 7. Further, a lower fixing portion 24 is provided at a position below the lower fixing portion 24 for tightening the lower belt 23 to tighten the instep below the ankle. For locking these belts, for example, the above-mentioned hook-and-loop fastener is used. The foot fixing mechanism 8 and the auxiliary upper fixing part 22 and lower fixing part 24 allow the entire foot to be fixed more firmly in the footwear 1.

  FIG. 4 is a perspective view showing another example of the foot fixing mechanism. In this foot fixing mechanism 7A, a first ring 15 and a second ring 16 are sewn to both outer sides of the upper 3 respectively. The base end 10d of the belt 10 is sewn and folded back through the first ring 15 to the second ring 16 to form the root 41 of the belt 10 and folded back by the second ring 16 to form the folded back portion 42. The tip of 10 is locked by the locking portion 13. At the time of belt tightening, the rear end of the folded portion 42 becomes the second ring 15. Other configurations are the same as those of the first embodiment.

  Also in this other example, the upper 3 can be tightened with a slight force in the linear direction L, and the foot can be firmly fixed in the footwear. By using a ring elastic member for the first ring 15 and the second ring 16, the bending movement of the foot caused by walking may not be hindered by the following of the belt 10 in the same manner as described above. Further, since the folded portion 42 overlaps the root portion 41 of the belt 10, the space where the belt 10 is exposed on the surface of the upper 3 can be reduced.

  In addition, although the above-mentioned foot fixing mechanisms 7 and 7A have the upper fixing part 22 and the lower fixing part 24 for assistance, any one or both may be omitted.

  FIG. 5 is a perspective view showing footwear 2 such as trekking shoes or athletic shoes according to the second embodiment. Unlike the first embodiment, the footwear 2 does not have a trunk. The foot fixing mechanism 7B is for fastening the instep 3 mainly to fix the instep in the footwear 1, the base end 10e of the belt 10 is sewn on the back side of the instep 3, and the root portion 51 and the folded portion 52 are formed. In a state where the belt 3 is overlapped in the linear direction L (oblique direction), the upper 3 is tightened, and the belt tip is locked by a locking portion 53 arranged on the straight line L extension of the root portion 51 and the folded portion 52. The foot is fixed in the footwear 2. In this case, the second ring 56 is a fixed pulley, and the first ring 55 and the outer shell (the left part in the figure) are pulled by the pulling force of the belt 10 and are drawn toward the second ring 56 (the right in the figure). Since the first ring 55 acts as a kind of moving pulley, the upper can be tightened with a small force. In this example, the lower fixing portion 54 is provided at a lower position for assisting the foot fixing mechanism 7B, but this may be omitted as necessary.

  As described above, in the present invention, in a state in which the folded portion overlaps with the root portion of the belt in the linear direction, the instep portion of the foot is tightened, and the belt is arranged on the linear extension of the root portion and the folded portion. Since the tip of the belt is locked to the locking portion and the foot is fixed in the footwear, the upper can be tightened with a slight linear force to securely fix the foot in the footwear. Further, since the folded portion overlaps the base of the belt, the space where the belt is exposed on the upper surface of the instep can be reduced. As a result, the foot can be easily attached and detached, and the foot can be fixed with a small force, so that the exposed space of the belt on the upper surface of the instep can be reduced and the foot can be hardly caught.

  Although the above-mentioned work footwear is applied to an underwear with a long torso, it may be applied to safety shoes having no torso or a relatively short torso.

  The present invention is not limited to the above embodiments, and various additions, changes, or deletions can be made without departing from the gist of the present invention. Therefore, such is also included in the scope of the present invention.
