Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to uppers (shoes) to be worn on a foot to which a lower limb orthosis is attached.

[0002]

[Prior art]

 Casting bandages used during trauma such as fractures and tendon ruptures are removed when the affected area has recovered to some extent, and plastic or leather appliances are used instead to protect the affected area. However, if the damaged part is the foot, even if the cast is removed, it may be inconvenient to go out. This is because it is still not possible to wear shoes that are usually used on legs with leg orthoses, and for example, instead of wearing shoes, it is possible to put on a plastic bag, for example. Is bad.

For this reason, exclusive shoes (shoes / boots) with a margin around the instep and ankle have recently been provided. Such shoes allow the upper to be openable and closable in order to make it easier to insert the feet, and the opening and closing part is Velcro to cope with the size (external size) of the lower limb orthosis, which varies depending on the degree of injury and the affected part. It has features that are different from ordinary shoes, such as being adjustable with fasteners (so-called magic tape; trade name).

[0004]

[Problems to be solved by the invention]

 However, conventional shoes have the following problems and are not always easy to use.

[0005] First, the conventional shoes have a so-called boat bottom shape in which the sole bottom surface U is curved as shown in FIG. The sole of the sole was made in this manner because a series of walking movements (first, the heel touched the ground, then the entire sole touched down, the heel rose as the body advanced, and finally the toe lifted from the ground) It is considered that this is the result of considering that the ankle is fixed, especially in the case where the ankle is fixed, but as shown in the figure, the lower limb orthosis G itself can walk indoors (without shoes). In many cases, the bottom of the boat is shaped in consideration of this, so that those with curved bottoms are stacked in two stages, lacking stability, making it more difficult to walk.

[0006] Second, in the conventional shoes, the upper part can be opened and closed with a Velcro fastener, but when the lower limb brace is large, the Velcro locking surface is reduced, and the fastener is frequently used during walking. Sometimes it came off. On the other hand, if the lower limb orthosis was not so large, the velcro edge would hang down excessively, impairing the appearance and hindering walking.

[0007] Therefore, an object of the present invention is to obtain a shoe structure that is easier to walk and looks good when worn on a foot with a lower limb orthosis.

[0008]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object and to solve the problem, the shoe for lower limb orthosis according to the present invention is provided with an opening / closing means on the upper part, and is a shoe that can be worn on a foot with the lower limb orthosis mounted thereon. A string or belt means that is formed almost flat while suppressing the front part of the ankle to prevent the lifting of the foot is provided inside the shoe, and the length of the string or belt means is adjusted according to the external size of the lower limb orthosis. An adjusting means for performing the above is provided. In such shoes, an opening / closing means may be provided on a heel portion covering the rear side of the ankle.

[0009]

[Action]

 As mentioned earlier, conventional shoes have a sole bottom with a boat bottom shape, and the bottom of lower limb orthosis often has a boat bottom shape as well. This resulted in instability and a lack of stability. Therefore, in the shoes of the present invention (shoes), the bottom surface of the sole is formed substantially flat. Flattening the sole bottom allows a stable ground contact to the ground and prevents the sole from swaying back and forth when standing or walking.

[0010] In this shoe, a string or belt means for holding down the front of the ankle is provided inside the shoe. This string / belt means prevents the lifting of the foot (lower limb orthosis) in the upper garment, and by attaching such a lace / belt, the unity of the lower limb orthosis and the upper garment increases, and the foot moves inside the upper limb during walking. And the comfort is good.

[0011] The string / belt means should be adjustable in length by suitable adjusting means (eg, a fastener or buckle). The purpose of this is to ensure that lower limb orthoses of different sizes depending on the degree of damage, affected area, etc. are securely suppressed in the upper limb and that the upper limb orthosis is adapted to the lower limb orthosis.

The upper of the shoe is provided with, for example, a fastener (zipper) for putting the foot in and out, and can be opened and closed. There is no need to provide an adjusting means on the upper as in the conventional case. This is because the string / belt means can ensure the integrity of the brace and the shoe. In addition, in the present invention, since the front of the ankle is supported inside the shoe by the string / belt, the force applied to the upper during walking is significantly reduced as compared with the conventional shoes. Therefore, it is possible to use Velcro or button hooks having relatively weak locking force as the opening / closing means of the upper part, so that the opening part does not come off and the upper part is opened during walking.

According to the second aspect, the heel portion that covers the rear side of the ankle is also provided with opening / closing means. This is because it is possible to put a foot from behind into the string / belt provided inside the shoe, and to easily attach the string / belt to the lower limb orthosis. As the means for opening and closing the heel, for example, Velcro, fasteners (zippers), button hooks and the like can be used in the same manner as the means for opening and closing the upper part.

[0014]

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. 1 to 3 show an example of a shoe for lower limb orthosis according to the present invention. As shown in the figure, the upper 11 is provided with a shoe main body 12 formed around the instep (width, thickness) and around the ankle on the upper surface of the sole 13 so as to cover the foot G to which the lower limb orthosis is attached. A fastener 14 is provided on the front surface of the main body so that the upper part can be opened and closed. The shoe body 12 is preferably formed of a waterproof material so that the lower limb orthosis does not get wet in rainy weather or the like. Specifically, for example, a resin sheet, synthetic leather, a composite sheet material obtained by integrating a resin and a cloth, and the like can be used. In addition, the height of the shoes should be such that the upper part of the ankle can be covered.

On the other hand, the sole 13 is formed of a resin plate having a cushioning property capable of absorbing a ground impact, and has a flat bottom surface from the front end to the rear end of the sole to secure the stability of the shoe. . The bottom surface of the sole 13 is formed with corrugations to prevent slipping and falling. Further, on the upper surface of the sole 13 (on the inner side of the shoe), an insole (not shown) made of cloth is arranged to prevent slippage (shift movement) between the shoe and the orthosis.

A lock cord 15 for suppressing the front part of the ankle is provided inside the shoe. The locking string 15 is arranged in a ring shape with both ends fixed to the left and right side edges of the sole 13, and the size of the ring R is shifted by shifting the clasp 16 that holds the string 15 upward or downward. It is possible to change the length. Therefore, by putting the foot in the ring R (locking cord 15) and adjusting the gripping position of the clasp 16 in accordance with the size of the lower limb brace, the brace G is lowered (obliquely rearward; the direction of arrow A in FIG. 3). The brace can be fixed to the sole 13 and the brace can be prevented from rising from the sole or moving in the shoe when walking.

Note that the locking cord 15 has a margin in length so as to be compatible with various sizes of equipment, and therefore, when the equipment is small, an end portion (a tip end of the metal fitting 16) is left. However, the surplus string end 15a can be stored in the shoe, and does not hang down loosely to impair the appearance of the foot or obstruct walking.

Further, the heel portion 17 covering the rear side of the ankle can be opened and closed. This is to make it easy to put the foot in and out of the shoe body 12 and the locking string 15 (ring R). The heel portion 17 is made to be able to be locked to the side surface of the shoe by a velcro 18, and the heel portion has an appropriate length (L) with the velcro 18a on the heel side facing the tip of the shoe. This is because the locking position of the heel (velcro 18a) with respect to the shoe side surface (velcro 18b) can be changed in the front-rear direction so that the size around the ankle can be adjusted.

The present invention is not limited to the embodiment described above, and the design of each component can be changed as appropriate. For example, in the embodiment, the locking cord 15 is fixed to the sole, but may be fixed inside the shoe body 12. Further, instead of the string (15), the ankle may be fixed by a resin belt or a cloth belt. In this case, for example, the length of the belt can be adjusted using a buckle. The opening and closing means of the upper part is not limited to fasteners, but Velcro or button hooks can be used. Further, it is advantageous in terms of waterproofness and cost to form the shoe body and the sole with a resin sheet or synthetic leather as in the embodiment, but it is also possible to use cloth, natural leather and other materials, and it is not necessarily required. The material is not limited.
