Description of the Related Art Conventionally, a shoe is known in which one side of a band is fixed to an upper and a hook-and-loop fastener is provided on the other side of the band so that the shoe can be tightened in order to make it easy to attach and detach the shoe. Further, as shown in FIG. 5, in a shoe having a sand guard for preventing sand from entering, one edge of the sand guard is fixed to the upper shell, and the other edge is in a released state so that the band and the sand There is known a shoe in which an abutment is connected with a connecting tool and the mouth is sufficiently expanded in synchronization with the movement of the band.
Utility Model No. 3062527

  However, particularly in infant shoes, consumers do not always purchase shoes suitable for the foot size, but may purchase shoes of slightly larger size. If one edge of the sand guard of a shoe that does not fit the foot size is fixed to the upper, the sand guard will not necessarily be placed in the proper position of the shoe when worn and will not perform its original function. There is a fear. In addition, there is a concern that the appearance may be deteriorated, such as when the sand guard moves to one side and wrinkles enter when worn. Furthermore, there is a demand for shoes that can cope with high and low legs in adult shoes.

  The present invention provides an easily attachable / detachable shoe in which the mouth can be widened in synchronization with the movement of the band when attaching or detaching the shoe, and the sand guard is disposed at an appropriate position of the shoe when the shoe is tightened. The purpose is to provide.

The easily removable shoes of the present invention are provided with a sand guard disposed on the back side of the upper so as to close the opening of the front upper part, and a band is bridged over the opening and one end is on the upper In shoes that are fixed so that the other end is detachable from the front side of the upper, the sand guard and the band are connected by a connector, and the upper end of the fixed end and the upper end of the removable end Are connected by a rubber elastic member, and the connecting position between the upper side of the detachable end of the band and the rubber elastic member is the toe side relative to the connecting position between the sand guard and the connecting tool in the front-rear direction of the shoe. The position is within 6% of the foot length size of the shoe and the heel side is within 10% of the foot length size of the shoe, and the rubber elastic member is configured to have a greater elongation when pulled with the same load than the connector . The fixed end side refers to the side on which the band is fixed, and the removable end side refers to the side on which the band is removable.

In the easily removable shoe of the present invention, it is preferable that the elastic rubber member has a larger elongation than the connector when pulled with the same load. Further, in the easily detachable shoe of the present invention, the rubber elastic member has a string shape or a belt shape, one end thereof is connected to the upper end of the fixed end side at a position closer to the toe, and the other end is the upper end of the removable end side. It is preferable that it is connected with a position close to the cover. Furthermore, it is preferable that the band has a band shape and is wide enough to hide the rubber elastic member when the opening is tightened.

  In the easily removable shoe of the present invention, the sand guard and the band are connected by a connecting tool, so that the detachable end side of the band is pulled toward the fixed end side with one hand, and the detachable end with the other hand. If the upper is pulled toward the detachable end, the sand guard is pulled toward the fixed end and lifts up, so that the wearer's mouth widens and the foot can be easily attached to and detached from the shoe. Since the fixed end side shell and the detachable end side shell are connected by a rubber elastic member spanned over the opening, sand removal is lifted up excessively by the rubber elastic member. Jumping out to the front side can be suppressed, and sand can be smoothly placed at an appropriate position when a band is put in and a band is tightened (when a shoe is tightened).

  Moreover, said effect can be heightened more by making a rubber elastic member into the raw material which is easier to extend than a connector. Further, by attaching the rubber elastic member to the upper shell with the fixed end side closer to the toe and the detachable end side closer to the heel, there is an effect that the wearing mouth can be more easily spread. That is, when the elastic rubber member is attached in parallel with the width direction of the shoe, when the upper end of the removable end side is pulled in the direction of the removable end to widen the mouth, the fixed end side connected by the elastic rubber member The upper shell may be pulled in the same direction, making it difficult for the wearer's mouth to spread. However, by moving the connection position of the rubber elastic member to the upper end of the rubber elastic member closer to the toe, Since it can be prevented from being pulled, the mouth is surely widened.

  Hereinafter, the present invention will be specifically described with reference to examples. The easily removable shoe 1 of the present invention is a shoe of the type in which the front part is fastened with a band as shown in FIG. In this embodiment, the upper 7 is formed integrally with the shoe sole so as to wrap around the foot from the base of the first heel to the base of the fifth heel via the heel. Yes. By forming the upper 7 in this way, the opening 8 is formed in the front. In the following, the present invention will be described with the upper 7 on the side to which the band is fixed as the upper 71 and the upper 7 on the side on which the band is detachable as the upper 72 across the opening.

  As shown in FIG. 1, the sand guard 4 is attached to the toe portion of the shoe by sewing or the like, and the rear portion is placed on the back side of the upper 7 so as to close the opening 8. Yes. Further, the sand guard 4 is sized so that the edge in the width direction overlaps the upper 7 in a state where the shoe is tightened, and the edge overlaps and contacts the back of the upper 7. Is not fixed by sewing.

  The sand guard 4 is preferably formed by covering a cushion material with a cloth. Sand removal is easily pulled out by the connector 2 and loses its shape, but by using a cushion material, it is possible to effectively prevent the shape from being lost due to the shape recoverability of the cushion material. The cushioning material is optimally flexible polyurethane foam, and has a thickness of 2 to 5 mm and a hardness of 50 to 200 N (JIS K6400).

  As shown in FIG. 1, the band 5 is bridged over the opening 8, one end is fixed to the upper 71 by sewing or the like, and the other end is detachably attached to the front side of the upper 72. The fixing of one end of the band to the upper 71 is not necessarily performed by fixing a separate band to the upper by sewing or the like. The protruding piece is extended from the upper 71 and this protruding piece is used as a band. It may be used. The band 5 is strong enough to withstand repeated tightening. For example, if a decorative fabric is sewed on the surface of the resin sheet and a hook-and-loop fastener 6 is sewed on the back surface, the necessary strength can be obtained.

As shown in FIG. 2, one end of the connector 2 is connected to the band 5 at a position near the detachable end of the shoe on the back side of the band, and the other end is detachable to the sand guard 4 on the front side of the sand guard. It is connected at a position closer to the end side. Further, the two coupling positions are positions that substantially coincide with each other at the time of tightening. In this case, the length between the two connections of the connector is 7 to 25% of the foot length size. Position that connects one end of the connector 2 to 4 except sand, that away 15% to 30% of the foot length size than the heel end of the exception sand in the longitudinal direction of the shoe. In the band 5 and the sand except 4 and a connecting child in connector 2 as described above, except the sand in synchronism with the movement of the band is lifted by successfully attracted to the fixed end. Moreover, it is preferable to use a material whose elongation is less than 5% even when a load of 500 g is applied. For example, a string-like body, a strip-like body, or a woven or knitted string made of woven fabric or knitted fabric is used.

  For example, as shown in FIG. 3, the connection tool is connected to the band by forming a slit 9 through which the connection tool 2 can be passed through the hook-and-loop fastener 6, passing the connection tool through the slit, and connecting the end of the connection tool to the band. By sewing to the fixed end side, it can be connected with good appearance. In this case, in the present invention, the connecting tool is connected at the position of the slit 9. For connecting the other end of the connector to the sand guard, for example, the other end of the connector may be overlapped on the surface of the sand guard and the two may be sewn together.

  As shown in FIG. 2, the rubber elastic member 3 has one end connected to the upper 71 and the other end connected to the upper 72. Further, the position where one end of the rubber elastic member is connected to the upper 71 is substantially coincident with the position where one end of the connecting tool is connected to the sand guard in the front-rear direction of the shoe.

  Here, the position that substantially matches in the front-rear direction of the shoe means a range that is within 6% in the toe direction and within 10% in the heel direction with respect to the foot length size of the shoe from the position that matches in the front-rear direction. When connected in the toe direction exceeding 6%, the sand guard tends to be unable to return to an appropriate position, and when connected in the heel direction exceeding 10%, the wear mouth tends not to spread. A more preferable connecting position is a range within 5% in the toe direction and within 6% in the heel direction from a position coinciding with the front-rear direction.

  Since the rubber elastic member 3 attached in this manner is stretched over the opening 8, when the shoe is widened, the rubber guard 4 prevents the sand guard 4 from jumping out excessively, so It has a function to smoothly return the sand guard to an appropriate position when tightening with a shoe (when tightening shoes). A preferred method of attaching the rubber elastic member 3 is that one end is connected to the upper 71 and a position close to the toe, and the other end is connected to the upper 72 and a position close to the heel so that the rubber elastic member 3 is bridged obliquely to the opening 8. It is an embodiment. The degree of the inclination is 15 to 60 ° when tightened with the line orthogonal to the longitudinal axis of the shoe. At this time, the position where one end of the rubber elastic member is connected to the upper 71 is closer to the toe in the front-rear direction than the position where one end of the connector 2 is connected to the sand guard 4. The rubber elastic member is preferably attached to the uppers 71 and 72 so as to be in a free state that does not expand and contract in the tightened state as shown in FIG. 1, and the elongation is 10 to 10 when a load of 500 g is applied. A material that is 100% may be used. For example, a string or band using rubber material or crimped yarn is used.

  As shown in FIG. 4, for example, when the hook-and-loop fastener 61 is attached to the upper 72 by sewing, one end of the rubber elastic member is sandwiched between the ends of the rubber elastic member. Therefore, it can be connected with good appearance by sewing at that time. The other end of the rubber elastic member may be connected to the upper 71 by, for example, sewing the other end of the rubber elastic member to the front or back surface of the upper 71.
