Abstract

<P>PROBLEM TO BE SOLVED: To provide a portable expansible shoe for outdoor use, which is adjusted in length in the case of a disaster or a travel. <P>SOLUTION: The middle part of a shoe sole part, in the portable expansible shoe, includes a dividing cross section inclined in a front and rear direction so as to be structured to be slidable forward and backward in a state where the upper surface 6 of the dividing cross section and the lower surface 5 are put together. The middle part of an upper shoe part has an integrally molded structure to be expansible in the front and rear direction, on which the shoe sole part is fixed to the upper shoe part excluding the middle part. Consequently, the shoe sole part is divided in carrying so as to easily fold the shoe. When the shoe is used, both the shoe sole part and the upper shoe part are fixed after extended/contracted in the front and rear direction within a fixed range. Thus, the portable expansible shoe is used as the shoe to be adjusted in length. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a portable shoe whose length can be adjusted at the time of disaster or during travel.

  Conventional folding shoes or portable shoes are mainly intended for carrying indoor shoes, and are not designed to be used outdoors (see, for example, Patent Document 1).

In addition, the conventional stretchable shoes or size-variable shoes are mainly intended for adapting to changes in the size of the foot accompanying growth, and are not a structure that takes portability into account (see, for example, Patent Document 2).

  In the conventional shoes described above, none of the shoes satisfies all the three features that the length of the shoes can be adjusted, it can be used outdoors, and it can be carried.

  The object of the present invention is to realize a shoe that combines all of these features with a simple mechanism.

  In order to achieve the above object, the present invention provides a first problem-solving means in which the shoe sole is divided into a front sole and a rear sole at the middle foot, and the divided cross section is inclined downward from the front to the rear of the shoe. Is provided. An upper surface and a lower surface of the divided cross section are configured to be fixed by adhesive, adhesive, double-sided tape, hook-and-loop fastener, uneven bonding, or the like. The upper part of the shoe composed of an impact buffer layer, an insole, a cloth part, and the like has an integrally formed structure.

  The upper part of the shoe integrally formed with the front bottom part and the rear bottom part of the shoe sole part divided by the middle foot part is fixed vertically except for the middle foot part.

  Further, as the second problem solving means, the divided cross section in the middle foot part of the shoe sole set as the first problem solving means has a structure that can slide the upper and lower surfaces of the divided cross section in the front-rear direction. A material having elasticity in the front-rear direction is set for the middle foot part or the whole shoe upper part.

  The effect | action by the said 1st problem-solving means is that the front-bottom part and rear-bottom part of a shoe-sole part are divided | segmented, Therefore It can fold compactly at the time of carrying. Furthermore, since the front bottom part and the rear bottom part of the shoe upper part and the shoe sole part are fixed to each other, they can be easily stored without being separated when carrying.

  Further, the second problem solving means has the function that the divided cross section in the middle foot portion of the shoe sole can slide in the front-rear direction, and the portion that is not fixed to the shoe sole portion in the middle foot portion of the shoe top is also in the front-rear direction. Therefore, the length of the foot can be adjusted within a certain range.

  As described above, the shoe of the present invention is used as a substitute when, for example, a shoe worn outside the home is damaged or a shoe not suitable for long-time walking such as high heels is worn when a large-scale earthquake occurs. It has the features of a shoe that can be carried around at any time.

  Also, even if the shoes you carry are handed over to others, they also have the feature of matching the length of the shoes to some extent.

  The above features can also be used as substitute shoes for travel and activities in areas where shoes are not readily available.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  The configuration of the present invention will be described with reference to FIG. Reference numeral 1 denotes an upper portion of a shoe, and is composed of an impact buffer layer, an insole, and a cloth portion that are integrally formed. 2 indicates a front bottom portion of the shoe sole portion, and 3 indicates a rear bottom portion of the shoe sole portion. Reference numeral 4 denotes a middle foot portion of the upper part of the shoe, which indicates a portion not fixed to the shoe bottom portion, and at least the middle foot portion is made of a material stretchable in the front-rear direction.

  Reference numeral 5 denotes the lower surface of the divided cross section of the front bottom portion, which is a surface on one side in the case of fixing with an adhesive, an adhesive application surface, or a combination of double-sided tape, surface fastener, and unevenness. Reference numeral 6 denotes an upper surface of the divided cross section of the rear bottom portion, which is a receiving side surface in the case of fixing with a combination of a double-sided tape, a hook-and-loop fastener, and unevenness. When a detachable material such as a hook-and-loop fastener is used as the fixing method, it can be folded again after use and carried.

  Since this invention consists of the above structures, the usage of this invention is demonstrated based on figures. FIG. 2 shows the shape when carried.

  FIG. 3 shows the shape before 5 and 6 are fixed. When using shoes, first try on the shoes in this state to confirm the optimal shoe length. Next, 5 and 6 are fixed to each other at the sliding positions 5 and 6 to obtain the optimum shoe length.

  FIG. 1 shows a state in which the shoe is fixed with the shortest length. FIG. 4 shows a state in which 5 and 6 are fixed by sliding 5 in the forward direction and 6 in the backward direction in order to extend the length of the shoe.

  The side view which shows embodiment at the time of adhering of this invention   The side view which shows embodiment at the time of carrying of this invention   The side view which shows embodiment before adhering of this invention   The side view which shows embodiment at the time of expansion | extension of this invention
