JP3063703U - Shoes that change the size of the mouth - Google Patents

Abstract

(57) [Summary] [Problem] When putting on shoes, the mouth opening is wide open and easy to put on, and after wearing, the latter half of the heel of the foot is softly wrapped and comfortable. SOLUTION: A mouthpiece forming bag 1 having a substantially O-shaped vertical cross section and a U-shaped bag shape in a plan view is attached inside the upper end portion of a heel curve at the rearmost position of the heel of the shoe. A bellows-like airbag 2 is formed inside the heel of the shoe, and a middle footrest 5 whose rear end moves up and down around the bent portion 4 is attached to the upper end of the airbag 2. The airbag 2 and the mouthpiece forming bag 1 are communicated with the ventilation pipe 9.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a shoe structure, and more particularly to a shoe in which a size of a mouth for inserting a foot is changed.

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, as the size of the inside of a shoe, a configuration in which an inner skin in close contact with the foot is formed in a bag shape inside the outer skin and air is injected into the inside to press against the foot is known. (See, for example, Japanese Utility Model Application Laid-Open No. 04-69011.) Also, when walking while walking with an air bag at the heel of the shoe, the air bag is compressed and inflated by the vertical movement of the heel to discharge heat and moisture inside. Are known. (For example, see Japanese Utility Model Laid-Open No. 04-9102)

[0003]

[Problems to be solved by the invention]

 The former, which puts air into the bag and presses the inner bag against the foot, as described in the prior art, always has air in the bag.Therefore, there is no gap when walking, while shoes are easy to walk, Be sure to insert the foot when putting on the shoe because the heel curve (referred to as the curve formed on the heel along the curve at the rear end of the heel of the foot) is always formed at the mouth of the shoe so that it does not come off. There was a problem that it was difficult, and the latter air bag provided on the heel did not help the fit of the foot even though the inside of the shoe could be ventilated.

[0004] In view of these problems, the present invention reduces the upper end of the heel curve and enlarges the opening of the slipper when the shoe is worn, so that the shoe can be easily worn without bending down and using a shoehorn, and the shoe can be removed. When walking, the foot should be pressed firmly along the curve at the back of the heel to wrap the ankle softly, and there will be no gap between the inside of the shoe and no slippage, and it will provide comfortable and comfortable shoes for walking. It is.

[0005]

[Means for Solving the Problems]

 Attach a U-shaped bag-shaped mouth-forming bag in plan view inside the upper end of the heel curve at the end of the heel of the shoe along the mouth, press the inside of the heel of the shoe with the heel of the foot, and push the insole down. An air bag for downward compression is provided, and the air bag and the mouthpiece forming bag are communicated with each other by a vent pipe.

[0006]

[Embodiment of the invention]

 The present invention will be described with reference to the drawings. In FIG. 1 to FIG. In the upper end portion of the heel curve C at the rearmost end (the upper half position of the conventional center of the moon), a U-shaped bag is formed along the mouthpiece H in a plan view. The step-stop air bag 2 is formed in a bellows shape with, for example, a rubber material, has a sponge 3 (for example, a soft polyurethane sponge-like foam) built in, and is attached to the inside of the heel of the shoe so as to expand and contract vertically. At the upper end of the stop air bag 2, a foot stop middle sole 5 formed by a heel / seat part of the middle sole whose rear end moves up and down around the bent part 4 is attached. More specifically, an abutment surface 6 is formed on the lower surface side of the stepping insole 5, and a receiving surface 8 is provided on the inner wall 7 of the heel at a lower position opposed to the abutment surface 6, respectively. When the middle foot 5 is depressed to a position where the contact surface 6 comes into contact with the receiving surface 8, the middle foot 5 is set to a height within the shoe suitable for walking.

The ventilation pipe 9 is formed of, for example, a plastic pipe made of vinyl chloride, and is attached so as to communicate with the inside of the airbag 2 and the inside of the mouthpiece forming bag 1.

Next, the method of use of the present invention will be described. In a state where the shoes are not worn, as shown in FIG. As the air bag 2 is raised and the air bag 2 is expanded, the air in the mouth forming bag 1 flows into the air bag 2 through the ventilation pipe 9 and the mouth forming bag 1 shrinks. It becomes wider and your feet are easier to put in. Next, when the foot is put in and the sole 5 is stomped down on the sole as shown in FIG. 2, the air bladder 2 shrinks, so that the air in the air bladder 2 reverses the above. After flowing into the mouth forming bag 1 through the ventilation pipe 9, the mouth forming bag 1 expands and wraps around the rear half of the heel and presses against it.

[0009]

【Example】

 If a spiral spring made of spring steel is used in the bellows of the air bag 2 for stepping, the resilience of expansion and contraction is improved and good results can be obtained. When the valve 10 for replenishing air is attached to the mouthpiece forming bag 1, the amount of inflation can be adjusted.

[0010]

[Effect of the invention]

 As explained above, the mouth before putting in the legs is wide and can be bent easily, and it is easy to use without using a shoehorn.Especially elderly people with weak legs can bend down or sit down. It can be easily removed without having to wear it, and even infants who do not wear their own shoes can make it easy for others to wear.After wearing, softly wrap the latter half of the heel and press it tightly. In addition, there is no need to worry about slipping off, as well as shoe slippage, and the comfort is very good.
