Description

  The present invention relates to an insole and footwear including an insole, and more particularly to a technique suitable for use in providing a shoe that fits the size and shape of a foot of a person wearing the footwear (hereinafter referred to as a user).

  Conventionally, it is known to arrange an insole in a shoe for various purposes. Such an insole is often used for the purpose of so-called fitting that matches the shape and size of a shoe with the shape and size of a foot, for example. Insoles with air permeability, deodorant function, cushion function, etc. are also commercially available.

  However, many insoles were merely a plate having a substantially constant thickness dimension formed into a foot shape. In this case, there is a problem that an effective effect cannot be expected in many cases with respect to a fitting function for shoes and a foot support function during walking.

  In view of such problems, some insoles with high functionality have been proposed. For example, in the insole shown in Patent Document 1 or the like, a pad is provided at a predetermined location and applied to a portion protruding or possibly protruding due to a hallux valgus, a hallux valgus, etc. By restraining, correction of hallux valgus is realized.

  However, in the case of the insole shown in Patent Document 1, Patent Document 2, etc., since only the portion protruding by the hallux valgus is pressed locally, this concentrates the pressure only on the protruding portion. As a result, walking may be painful. Moreover, it was not effective treatment or prevention only by forcing the protruding part by the hallux valgus.

  In particular, it has hardly been desired to fit fittings of shoes that have already been manufactured and whose internal shape is limited so that there is no excess or deficiency for each of the variously shaped feet. That is, the size of the shoe length is generally in increments of 5 mm, and there is often only one type of shoe having a different width dimension at each store for each length. In that case, it was difficult to fit so that there was no excess or deficiency only with the insole laid on the shoe sole.

  In addition, if you wear large shoes to reduce the burden on the toes, the toes will move in the front-rear direction inside the shoes in the dynamic state such as walking and running, and eventually the toes In other words, the desired function and effect cannot be exhibited. Furthermore, there is a problem that large shoes are difficult to walk during dynamic walking.

  In particular, in women's shoes, especially high heels, the force that moves the foot forward always acts inside the shoes, so the force applied to the toes becomes very large, causing problems such as hallux valgus. There was an easy problem. In addition, as a result of the toes being pressed by the shoes, the function of the toes freely moving has been hindered.

In order to solve such problems, the inventor of the present application has proposed an insole and an insole including an insole capable of improving a fitting function for shoes and a toe movement function in Patent Document 2. In Patent Document 2, the user's foot is restricted from moving forward in the shoe by contacting the user's sole tip on the insole corresponding to the user's sole tip. By providing a detachable foot tip support, the foot support of the foot and the heel of the shoe can restrict the movement of the user's foot in the front-rear direction inside the shoe. ing.
JP 2000-287705 A JP 2008-23290 A

  The invention described in Patent Document 2 requires a resistance force to the moving force in order to be able to regulate the movement of the user's foot in the front-rear direction inside the shoe. In this case, the resistance force when the user's foot moves in the forward direction is the force acting in the direction in which the insole extends from the heel side where the weight is on, so the insole is a flexible member Even if it comprises, sufficient resistance can be obtained.

However, when the user performs an exercise to bend the toes, the force acts in the direction of pulling the bottom tip support to the heel side, i.e., the direction in which the insole contracts, so the insole is made of a flexible member. If it is, sufficient resistance cannot be obtained. In order to obtain sufficient resistance in the direction in which the insole contracts, if the insole is made rigid, there is a problem in that the flexibility of the user's sole tip cannot be obtained.
In view of the above-mentioned problems, the present invention provides an insole and an insole including an insole that can improve a fitting function for a shoe and a toe movement function and can provide flexibility to a tip end portion of a user's sole. The purpose is to be able to provide.

  The insole of the present invention is an insole that is used by being attached to footwear. The insole is configured to have a double side structure of a lower insole and an upper insole from at least approximately half, and the foot tip of the user A plantar tip support that is brought into contact with the user's plantar tip at a position corresponding to the portion is provided between the lower insole and the upper insole so as to be adjustable in position. To do.

  The footwear provided with the insole of the present invention is characterized by wearing the insole described above.

According to the present invention, the movement of the user's foot forward in the footwear by abutting the user's foot tip at a position corresponding to the user's sole tip is restricted. Since the sole tip support body to be attached is detachably provided, it is possible to provide an insole capable of improving the fitting function and the exercise function for the footwear and the footwear including the insole.
Further, according to another feature of the present invention, the foot tip support is provided to be detachable from the insole, so that it can cope well with a user whose left and right foot sizes are slightly different. be able to.

(First embodiment)
As shown in FIG. 1, the insole 20 of this embodiment has a sole tip end support 30 between the lower insole 20a and the upper insole 20b, and the insole 20 is mounted in the shoe. The sole tip support 30 is interposed between the lower insole 20a and the upper insole 20b. The lower insole 20a has an appropriate rigidity, and as described later, a great resistance force is obtained with respect to the force that moves the foot tip support 30 in the heel side direction by the user's toe movement. It is made to be able to. On the other hand, the upper insole 20b and the plantar tip support 30 are made of a flexible member so as to flexibly contact the user's plantar tip.

  In the present embodiment, the position of the bottom tip support 30 can be adjusted. A position adjusting mechanism 250 is provided so that the position of the sole tip support 30 can be easily adjusted. The position adjusting mechanism 250 forms left and right guide grooves 251 and 252 along the longitudinal direction of the lower insole 20 a, and a slider 253 is disposed in the guide grooves 251 and 252. A part support 30 is attached.

  2A and 2B, the slider 253 is configured in a frame shape so as to hold the lower insole 20a. Further, as shown in FIGS. 2B and 3, the lower slider 253 includes an engaging portion 253 a at a substantially central portion on the back surface of the lower insole 20 a. The engaging portion 253a is provided to fix the slider 253 to the lower insole 20a at a predetermined position, and one surface fastener 254 is provided on the surface facing the lower insole 20a. It is attached. Moreover, as shown in FIG. 3, the other surface fastener 255 couple | bonded with one surface fastener 254 is attached to the lower insole 20a. With such a configuration, the slider 253 can be securely fixed at a predetermined position of the lower insole 20a by engaging the one surface fastener 254 with the other surface fastener 255.

  The sole tip support 30 has a thick central portion and is formed to become thinner toward both sides. This is because, as will be described later, when the user's sole tip is supported, it can be supported along the lateral arch of the sole tip. In addition, since the upper of the shoe is configured to become lower as it goes to both sides, it is also for preventing the user's foot from becoming cramped. The foot tip support 30 is preferably made of a material such as synthetic rubber having both elasticity and rigidity. By comprising in this way, the front-end | tip part of a user's sole can be supported reliably and flexibly.

  As shown in the perspective view of FIG. 4, the insole 20 of this embodiment has a sole tip support 30 attached between the lower insole 20a and the upper insole 20b. There is no foreign matter on the surface of 20b. Therefore, it is possible to smoothly advance and retract the tip of the user's foot on the surface of the upper insole 20b, and when the user attaches or detaches the shoe, the foot tip support 30 is attached to the foot of the user. There is no inconvenience of being caught on the tip.

  In the present embodiment, as shown in FIG. 3, the upper insole 20b covers the surface of the lower insole 20a and the bottom tip support 30 and the end of the upper insole 20b is the lower insole 20a. It is folded and bonded to the back side. Thereby, the lower insole 20a and the upper insole 20b can be integrally configured, and the appearance can be improved. The upper insole 20b and the lower insole 20a may be simply bonded together. In any case, in order to make it possible to adjust the position of the plantar tip support 30 in the front-rear direction, the upper insole 20b and the lower insole 20a are arranged in the movement region of the plantar tip support 30. A free space is formed between them.

  FIG. 5 is a diagram illustrating an example of a state in which the user is wearing the shoe 100 wearing the insole 20 of the present embodiment. As shown in FIG. 5, in the shoe 100 in which the insole 20 of the present embodiment is mounted, the tip of the bottom of the foot so that the bottom of the foot tip support 30 is in contact with the tip of the sole 201 of the user. The position which arrange | positions the part support body 30 between the lower insole 20a and the upper insole 20b is adjusted. As described above, in this embodiment, the foot tip support 30 is attached on the slider 253, and the slider 253 is movable in the front-rear direction of the insole 20, so that the foot tip support 30 is attached. The position can be easily adjusted and can be freely performed any number of times.

  When the foot tip support 30 is attached to an appropriate position between the lower insole 20a and the upper insole 20b, the foot tip support 30 is in the state of the user wearing the shoes 100. Abuts against the tip 201 of the sole. That is, the plantar tip support 30 is positioned below the toe base 202. Thus, the user's foot 200 can be supported by the heel portion 101 and the foot tip portion support body 30 in the front and rear direction within the shoe 100.

  That is, in this embodiment, the “user's sole dimension x” shown in FIG. 5 is regarded as the “foot support dimension” unique to the user, and the “user's sole dimension x” is regarded as the tip of the sole. It can be firmly supported by the part support 30.

  Conventionally, “size y of the user's foot” from the heel portion 101 of the shoe to the tip portion 203 of the toe is regarded as a “foot support dimension” unique to the user, and this “size y of the user's foot” is considered. Is supported by the heel portion 101 of the shoe and the tip portion 102 of the shoe. Therefore, the movement of the user's foot 200 in the rearward direction within the shoe 100 is restricted by the shoe's heel part 101, and the movement of the user's foot 200 is restricted by the tip part 203 of the user's toe. It was.

  Accordingly, even if the “shoe size z” from the heel 101 to the tip 102 of the shoe is increased, as long as the user's foot 200 moves forward with walking, a large force is applied to the user's toes. It is very difficult to reliably avoid the action. For this reason, as is well known, the risk of occurrence of obstacles such as “valgus valgus” and “varus valgus” depending on the state of the foot of the user and the shape of the shoes could not be avoided reliably. .

  On the other hand, in the present embodiment, the foot 200 of the user moves back and forth inside the shoe 100 by the foot tip support 30 attached to the position of the user's foot sole dimension x and the heel 101 of the shoe. It is possible to reliably restrict movement in the direction.

  In particular, in the present embodiment, since the foot tip end support 30 is attached between the lower insole 20a and the upper insole 20b, no foreign matter exists on the surface of the upper insole 20b. Thus, as described above, when the user takes off or puts on the shoes, the user's toes 204 can smoothly advance and retract the surface of the lower insole 20a and the upper insole 20b.

  As described above, the insole 20 of the present embodiment supports the user's sole tip 201 and is particularly effective when applied to, for example, high heels. That is, even when the user's foot is easy to move forward, as in high heels, the foot tip support 30 can reliably support the user's foot moving forward. . This makes it possible to secure a “free space” at the tip of the toes even in shoes that are tapered, such as high heels that prioritize fashion, and from the side of the shoe to the user's toes. It is possible to reliably prevent a large force from acting. That is, in the insole of this embodiment and the shoe provided with the insole, both fashionable and toe health can be satisfied.

  As shown in FIGS. 6A to 6C, the insole 20 of this embodiment is suitable for exercising the user's toes 204. That is, as shown in (a) of the explanatory diagram of the usage example shown in FIG. 6, the bottom tip support 30 is usually positioned on the bottom tip 201 of the user and below the base 202 of the toe. Is pressed. In this case, since the foot tip end support 30 restricts the user's foot tip 201 from moving forward, it presses the user's foot tip 201.

  As a result, it is possible to alert the user to perform the toe movement, and as shown by the white arrow in FIG. It is possible to exercise without forgetting to repeatedly perform the exercise of hanging on the body 30 and pulling it toward the front, which is effective for training the plantar muscle 210. Such an exercise of pulling the sole tip support 30 with the user's toes 204 can be performed at any time, which can greatly help to eliminate the lack of leg movement.

  For example, when the insole 20 of this embodiment is attached to commuting (commuting) shoes, it is possible to contribute to performing an effective exercise on the legs on the train. That is, in the insole 20 of the present embodiment, the flexible foot tip support 30 is always in contact with the user's foot tip 201. For this reason, the user is always aware that a foreign object comes into contact with the sole tip 201.

  Therefore, for example, if it is decided to exercise the toes of the foot on a commuting (commuting to school) train, the presence of the foot tip support 30 is occasionally felt and the forehead of the toes is forgotten. It will disappear, and you will be able to continue exercising your toes.

  Further, as shown in FIG. 6C, the user's toes 204 are moved upward as shown by the white arrows in FIG. The muscles used during exercise can be stretched and the muscles on the shin side of the foot and other muscles that were not used much during the exercise of the toes of the foot in FIG. 6B can be trained. it can.

  By performing exercises as shown in FIGS. 6B and 6C, it is possible to exercise the sole muscles 210 as well as the muscles of the entire leg and the waist muscles. . This effectively prevents deep vein thrombosis (DVT, also known as economy class syndrome), which occurs when the lower body becomes under-exercised, for example, when the vehicle is in a vehicle for a long time. Further, by performing such an exercise, the muscles of the sole can be trained, and it is effective for forming horizontal and vertical arches.

  In addition, since the insole and the shoe including the insole according to the present embodiment can be always conscious of pressing the user's toes 204 against the shoe 100, it is convenient to be applied to various sports shoes.

  For example, golf shoes will be described as an example. The basics of golf swings are said to be firmly stroking the lower body. In order to do this, it is better to do the address by grabbing the ground with the sole of the foot, but when you actually hit the golf ball, only the upper body is in force and it will be neglected to straddle the lower body Is most.

  As described above, the shoe having the insole and the insole according to the present embodiment is in contact with the foot tip 201 of the user, so that the foot tip support 30 having flexibility is in contact with the user. At the time of addressing, you can be sure of your foot condition. This makes it possible to prevent a person from paying attention to hitting a golf ball and forgetting to address with a firm foot on the sole of the foot, and to perform a swing faithful to the basics. it can. Specifically, as shown in FIG. 6 (b), it is possible to prevent the user from forgetting to perform an address to hold the shoe sole firmly while standing with the user's toes 204 standing. .

  In the above-described embodiment, the foot tip support 30 is disposed between the lower insole 20a and the upper insole 20b via the slider 253 so that the position can be adjusted. However, the plantar tip support 30 may be attached between the lower insole 20a and the upper insole 20b via, for example, a double-sided tape. Specifically, the lower insole 20a and the upper insole 20b are attached via one surface fastener and the other surface fastener at least from the substantially central portion of the insole 20 to the tip side, and are detachably attached. Try to put it on. Thus, by attaching the lower insole 20a and the upper insole 20b via the hook and loop fastener, the bottom tip support 30 is positioned in the state where the foot tip tip 201 is positioned on the user's bottom tip 201. It can be disposed between the side insole 20a and the upper insole 20b.

  In the above-described embodiment, the example of the insole extending over the entire length of the shoe sole has been described. However, for example, the insole may be approximately the size of the front half of the sole. Such a half-size insole is suitable for use in women's high heel shoes and the like in which the inside of the shoe is exposed.

  In the above-described embodiment, one surface fastener is attached to the bottom portion of the shoe 100 and the other surface fastener is attached to the back surface of the insole 20. The other surface fastener may be attached to the back surface of the insole 20 in advance at the time of factory shipment. Moreover, what is necessary is just to attach one hook-and-loop fastener to the bottom part of the shoe 100 in the position corresponding to the other hook-and-loop fastener after the arrangement position of the insole 20 is decided. Attaching one hook-and-loop fastener to the bottom of the shoe 100 can be performed via a double-sided tape, for example. The user's sole can be supported by the heel portion 101 and the foot tip support 30 in the same manner as described above with reference to FIG.

  By fixing the insole 20 and the bottom portion of the shoe 100 with one surface fastener and the other surface fastener, the size of the insole 20 can be used satisfactorily even if it does not exactly match the internal size of the shoe 100 Can do. The advantage is that, for example, the insole 20 is formed in a rough size such as a large size, a medium size, and a small size, and detailed adjustment of the arrangement position is related to one surface fastener and the other surface fastener. It can be done together.

  Such a configuration makes it unnecessary to cut the insole 20 with a kite and is convenient in an airplane where it is difficult to use the kite. That is, the insole 20 can be disposed and used inside the shoe 100 without using a bag in an airplane where the economy class is the most problematic. Moreover, you may comprise the insole 20b using a several material like the 1st member which has a softness | flexibility, and the 2nd member which coat | covers a 1st member in order to give durability.
