Description

  The present invention relates to a sock shoe with a size adjustment function using a sock-like upper sole, and in particular, a shoe sole is divided into three parts, a toe sole, a heel sole and an intermediate sole, and the toe sole and the heel sole thereof are By changing the size of the intermediate sole that is fixed to the bottom of the sock component and is detachably attached between them, the overall size of the sock shoe can be adjusted integrally. It relates to sock shoes with size adjustment function.

  In general, a shoe is composed of an upper sole made up of an upper part and a heel part that covers the upper part of the foot, and a shoe sole that protects the lower part of the foot. In this, the upper part and the heel part must be manufactured in three dimensions by cutting the flat material according to the shoe shape prepared for each size and gluing, laminating and sewing each part. However, it takes time and labor to produce shoes, which increases the manufacturing cost of shoes.

  On the other hand, in order to solve such problems, in Japanese Utility Model Publication No. 57-180707 (Patent Document 1) and Japanese Utility Model Application Publication No. 58-129802 (Patent Document 2), A sock with a shoe sole in which a rubber-like sole portion is bonded has been proposed. Further, in Japanese Patent Application Laid-Open No. 2004-105323 (Patent Document 3) and Japanese Patent Application Laid-Open No. 2007-236612 (Patent Document 4), a softening point is applied to a specific portion of the sock to further improve the fit with the foot. A low-cost, high-fit sock shoe that has been molded into a three-dimensional shape by knitting synthetic resin fibers or arranging a shape-supporting support member on the surface or inside of the sock and heat-treating it has been proposed. Yes.

  However, because the upper sole made of sock parts is made of an elastic material, its size is adjusted appropriately according to the size of the wearer's foot, but the sole that is attached to the bottom of the upper sole is a sock Since it is made of a synthetic resin material that can hardly expand and contract compared to the material, the size is not adjusted according to the size of the wearer's foot.

  For this reason, in conventional sock shoes, even if the upper sole has a size adjustment function, the wearer must eventually select a sock shoe having a sole that matches the size of his / her foot, and The manufacturer also has the disadvantage of having to manufacture and prepare sock shoes for each size sole.

  On the other hand, JP-A-8-205906 (Patent Document 5), JP-A-2008-517699 (Patent Document 6) or US Pat. No. 6,164,642, US Pat. In US Pat. No. 2,497,175, US Pat. No. 3,389,481 and US Pat. No. 6,138,385 (Patent Documents 7-11), the shoe sole is divided into a toe portion and a heel portion, and both are slidably arranged on a tongue-shaped shank plate. A shoe sole that can be adjusted to any size by mounting and fixing, or by fixing an arch member of different size between the toe and the heel, or a shoe having such a shoe sole is disclosed. Yes.

  However, these size adjustable soles or shoes with such soles can be sized by adjusting the size of the sole and then attaching a suitable fixed size non-stretchable upper sole. An upper sole that can be adjusted (see Patent Document 5) or can be attached to a shoe sole that is divided into a toe portion and a heel portion is also a toe portion such as a sandal shoe. There was a problem that it was limited to those having a shape completely separated from the heel part (see Patent Documents 6 and 8).

  In addition, these shoes having adjustable soles are based on the use of an upper sole made of a relatively hard material such as natural leather (see Patent Documents 5 and 7-10). The adjustable shoe sole must be provided with a tongue-shaped shank plate to retain its shape and ensure close contact with the wearer's sole, which complicates the sole structure was there.

  In addition, other types of adjustable shoe soles or shoes having such soles may include a portion of the upper sole as described in US Pat. There is known a shoe in which a stretchable structure such as a bellows is provided in a portion corresponding to the above, and the size of the shoe in the longitudinal direction can be adjusted even during normal use.

  However, even in the case of these types of size-adjustable shoes, the structure of the upper sole, in particular, the stretchable part and the sewing part between the stretchable part and the other part becomes extremely complicated, and as a result, the produced shoes There was a problem that the durability of the resin deteriorated and the cost became expensive.

Japanese Utility Model Publication No. 57-180707 Japanese Utility Model Publication No. 58-129802 JP 2004-105323 A JP 2007-236612 A JP-A-8-205906 JP 2008-517699 A U.S. Pat. No. 641642 U.S. Patent No. 2009684 U.S. Pat. No. 2,497,175 U.S. Pat. No. 3,389,481 US Pat. No. 6,138,385

  Therefore, in view of the above problems, the present invention has a high ease of attachment / detachment at the time of wearing, an adjustability, and a high fit after wearing, and a durable shoe sole is integrally fixed to the bottom thereof. The size of the shoe is very simple and the size of the sole can be adjusted, and when changing the size of the sole, the size of the upper sole attached to the sole is also adjusted at the same time. An object is to provide a shoe with an adjustment function.

  In order to achieve this object, the present inventors have intensively studied. As a result, sock-like sock parts that can be stretched in the longitudinal direction are applied to the upper sole of the shoe, and the shoe sole is fixed to the upper sole. The size of the intermediate sole can be changed to an arbitrary size by applying a shoe sole divided into three parts: a toe sole and a heel sole, and an intermediate sole that is detachably attached between them. As a result, we have completed sock shoes with a size adjustment function that can adjust the overall size of the sock shoes.

  That is, according to the present invention, there is provided a shoe sole comprising a sock-like upper sole having a bottom portion and at least stretchable in the longitudinal direction, and a toe sole, an intermediate sole and a heel sole divided from each other. The sole and the heel sole are fixed to the bottom of the upper sole, and the intermediate sole includes the shoe sole that is detachably attached between the toe sole and the heel sole by a locking means. By changing, the distance between the toe sole and the heel sole is adjusted, and at the same time, the size of the upper sole fixed to the toe sole and the heel sole is also adjusted integrally. Functional sock shoes are provided.

  In the sock shoe of the present invention, a sock component having a bottom portion as an upper sole and stretchable at least in the longitudinal direction is used. For this reason, although the sock shoe with size adjustment function of the present invention has a very simple structure, it is possible to freely adjust its size corresponding to the size adjustable sole, Even if a subtle difference in the size of the foot occurs between the wearers or between the left and right feet of the same wearer, the fit can be made without difficulty.

  Further, in the present invention, the sock component itself used for the upper sole has a bottom portion, and has a high fit and adjustability that fits and adheres naturally to the wearer's foot shape (especially the sole). The bottom has the advantage that it is not necessary to dispose a tongue-shaped shank plate for the purpose of further improving its shape retention, adhesion to the wearer's sole, and the like.

  Furthermore, since socks are used in the upper sole in the present invention, the socks inherently have high stretchability and breathability, touch and comfort, and high detachability that cannot be obtained with ordinary shoes. Many functional benefits can be enjoyed. In addition, the sock shoes according to the present invention can be provided at an extremely light weight and at a low cost.

  The shoe sole attached to the upper sole is composed of three parts separated into a toe sole, an intermediate sole and a heel sole. Among them, the toe sole and the heel sole are fixed to the bottom of the upper sole so as not to be removed by adhesion or welding, and the intermediate sole is detachably attached between the toe sole and the heel sole by a locking means. A plurality of intermediate soles having different sizes (lengths) are prepared on the shoe sole, and the size of the entire sock shoe is integrally adjusted by exchanging them.

  The toe sole and the heel sole are required to have wear resistance and durability from the viewpoint of direct contact with the ground and the like, and from the viewpoint of maximizing the functions of the socks constituting the upper sole, It is required to have flexibility and elasticity and to be lightweight. Therefore, the toe sole and / or the heel sole may be molded from natural rubber, synthetic rubber, EVA, polyurethane, nylon, polyester material, natural leather, synthetic leather, or the like as commonly used for shoe soles. it can.

  In addition to or in place of the functions required for the toe sole and the heel sole, the intermediate sole is required to have an appropriate rigidity that firmly holds the distance between the toe sole and the heel sole. Therefore, the intermediate sole can be molded from the same material as the toe sole or heel sole as described above, and has higher rigidity than epoxy resin, glass fiber reinforced resin, carbon fiber reinforced resin or iron, aluminum, stainless steel material, etc. It can also be formed from a material having

  In addition, the toe sole and the heel sole have different functions required for the adhesion surface on the side that adheres to the bottom of the upper sole and the ground contact surface that contacts the ground, so each is divided into a midsole and an outsole, Then, you may use what integrated both.

  The locking means of the intermediate sole may be one that fixes the intermediate sole to the bottom of the upper sole in cooperation with the locking means provided on the bottom of the upper sole, or a lock provided on the toe sole and the heel sole. The intermediate sole may be fixed to the toe sole and the heel sole in cooperation with the stopping means. Moreover, when more reliable fixing of the intermediate sole is desired, both locking means may be used in combination.

  In addition, as a specific locking means for the intermediate sole, there is no particular limitation as long as it has a function and a structure for detachably and strongly joining the intermediate sole between the toe sole and the heel sole. A locking means can be used, for example, a concave-convex fitting type locking means such as Lego (registered trademark), a snap-type locking means using buttons or hooks, a screw-type locking means using screws, etc. A locking means, a screwing or inserting type locking means, a two-surface fastener type locking means such as Velcro (registered trademark), a slide insertion type locking means from the side surface, or the like can be used.

  Therefore, according to the present invention, by changing the size of the intermediate sole, the distance between the toe sole and the heel sole is adjusted, and at the same time, the size of the upper sole joined to the toe sole and the heel sole is also adjusted. As a result, the overall size of the sock shoe is adjusted integrally.

  Further, in the sock shoe of the present invention, the shoe sole divided into three parts, together with the sock's high fitting function and adjusting function, adheres to the wearer's sole and follows the movement of the sole. It also plays a role to further improve.

  Further, in the present invention, when it is intended to further enhance the durability of the sock shoes for the purpose of strengthening the outer wear function or the like, a shank plate for keeping the shape constant may be provided on the shoe sole. .

  In this case, the shank plate is preferably formed from an elastic band plate such as metal or plastic, and the fixing method is not particularly limited. For example, the tip of the shank plate is attached to the toe sole. It is preferable that the rear end of the shoe is fixed and slidably held on the shoe sole of the shoe by being inserted into a slit-like slot provided on the front side surface of the heel sole.

  In the sock shoe with size adjustment function according to the present invention, the shoe sole is connected to the toe sole and on one side of the toe sole in order to make the shoe sole follow the movement of the sole of the wearer more smoothly. An upper portion holding belt extending from the edge portion of the upper sole to the edge portion on the other side so as to cross the upper portion of the upper sole in the width direction can be provided. Also, for the same purpose, the sole may be provided with a heel cover connected to the heel sole and extending from the peripheral edge of the heel sole to the heel of the upper sole so as to cover the heel. The effect is further enhanced by using it together with the upper part holding belt. The heel cover is preferably bonded to the heel portion of the upper sole.

  Specifically, the upper part holding belt disposed across the upper part of the upper sole from the side edge of the toe sole improves the holdability of the upper part by being connected to the toe sole. It acts to make the deformation of the toe sole follow the movement of the toe of the wearer's foot. Further, the heel cover disposed so as to cover the heel portion from the rim portion of the heel sole to the heel portion of the upper sole retains the rising shape of the heel portion of the upper sole and is connected to the heel sole. It works to make the deformation of the heel sole follow the movement of the heel of the wearer's foot.

  As a result, the sock shoes with the size adjustment function to which the upper part holding belt and / or the buttock cover are attached have improved fit and unity with the toes and / or heels of the wearer, and the soles of the wearer The shoe soles (toe soles and heel soles) can be made to follow the movement of the shoe without difficulty.

  Furthermore, if one wants to give the heel sole a higher hold on the wearer's ankle, one end is fixed to one side of the heel cover and the other end is the wearer's ankle. An ankle holding belt that is detachably fixed to the other side of the heel cover by the second locking means can be attached.

  As a result of the above, according to the present invention, it has high detachability at the time of wearing, adjustability, and high fit after wearing, and a durable shoe sole is integrally joined to the bottom thereof. Size adjustment function that the structure of the shoe sole is very simple and the size of the sole can be adjusted, and when the size of the sole is changed, the size of the upper sole attached to the sole is also adjusted at the same time Shoes with can be provided.

  In addition, according to the present invention, since socks are used for the upper sole, socks such as high stretchability and breathability, good touch and comfort, and high detachability that cannot be obtained with ordinary shoes are inherently provided. Can enjoy many functional advantages and can fit comfortably even if there is a slight difference in foot size between wearers or between the left and right feet of the same wearer . In addition, there is an effect that the sock shoes with size adjusting function according to the present invention can be provided at an extremely light weight and at low cost.

  Hereinafter, sock shoes with a size adjusting function according to an embodiment of the present invention will be described in detail with reference to the drawings.
