    [0002]
    [0003]
    [0004] OBJECT OF THE INVENTION
    [0005] The present invention relates to a shoe with an orthosis that assists the patient during gait or physical activity by holding and strengthening the Achilles tendon, avoiding overexertion of the tendon, pain, discomfort or the possible arrest of the activity due to the above causes.
    [0006]
    [0007] It finds special application in the field of two sectors: footwear and orthotics, including the design, manufacture and development of a hybrid product dedicated to facilitate the daily physical activities of a user with a weak Achilles tendon.
    [0008]
    [0009] TECHNICAL PROBLEM TO BE RESOLVED AND BACKGROUND OF THE INVENTION
    [0010] Footwear is the clothing that surrounds and protects the foot and / or part of the leg while an orthosis is an external support adapted to the human body that changes structural or functional aspects of the musculoskeletal system. Between their functions both have in common that they protect and help the user with their application. In this case the affected areas are the foot, the ankle and part of the lower leg.
    [0011]
    [0012] The shoes were born as the need to protect the feet from external agents and environmental, thermal and mechanical changes when the human being began to walk in a standing position, that is, in prehistory. But protection is not the only function that must be fulfilled, it must also allow the foot to fulfill its function and favor gait so that it is normal and physiological.
    [0013]
    [0014] The study to ensure that the functions of footwear are optimal, is done through biomechanics, which is defined in the Royal Spanish Academy as the science that studies the applications of the laws of mechanics to the structure and movement of beings alive together with the ergonomics or the study of the adaptation of devices and the environment to the human being to offer greater comfort and efficiency.
    [0015] Although the footwear was born as a functional product, it has ended up becoming a fashion accessory due to social, economic and aesthetic factors.
    [0016]
    [0017] The structure and design of the footwear adjusts to changes in fashion trends, which are constant, and biomechanical and ergonomic aspects are abandoned, resulting in injuries, malformations, discomfort and discomfort in the feet of the users, the ankle and the leg, mainly. But these problems can spread to the hip and back.
    [0018]
    [0019] On the other hand, orthoses are born in 3,000 a. C. when the human being begins to implant them with the tools, knowledge and materials available to them. However, these orthoses did not quite adapt completely, but they have evolved to those that are built today with the help of advanced technologies. In Egypt, stone engravings dating from 2,800 BC have been discovered. C., which show the use of crutches, and papyri dating back to 1,600 a. C. in which orthoses of bamboo, cane, wood, tree bark and linen pads are appreciated.
    [0020]
    [0021] In 1,500 B.C. Hippocrates used splints and pads that were fastened with leather bands for fractures.
    [0022]
    [0023] In the fifth century is when exoskeletal joints begin to appear that provide movement to the knee and foot.
    [0024]
    [0025] Articulated, metal and steel orthoses appear during the 16th-20th centuries.
    [0026]
    [0027] In 1960, thermoplastic polymers for orthotics and orthopedic devices began to be applied due to their molding when heat was applied.
    [0028]
    [0029] On the contrary, it is not until 1973 when Harris unifies the definition of orthosis to develop terms.
    [0030]
    [0031] Currently, orthoses are still manufactured in very different materials and shapes. In materials, thermoplastics (polyethylene and polypropylene), elastomers (wetsuits and silicone), textiles, metals (aluminum, steel, titanium and copper) and composite materials (wood, textile fiber and carbon fiber, fiberglass and Kevlar) stand out .
    [0032] Here are some documents from both sectors as a non-limiting example:
    [0033] - ES2434998_T3: Shoe orthosis
    [0034] - ES2633348_T3: Orthopedic Sandal
    [0035] - ES2635553_T3: Orthopedic device for a lower limb of a person - ES2630428_T3: Orthosis
    [0036] - ES2364364_T3 Sock footwear with padded layer
    [0037] - ES2383183_T3: Therapeutic footwear
    [0038]
    [0039] In the current market, orthoses and shoes are usually sold as separate products and in some cases the orthopedic shoe can be used. However, the aesthetics of these products, the discomfort of having two products separately, that do not adapt completely to the user or that do not meet all the functional requirements are some of the factors that arise from not buying them. For all the above, the following invention has been developed.
    [0040]
    [0041] DESCRIPTION OF THE INVENTION
    [0042] The object of the present invention is the design of a hybrid product between footwear and removable orthosis for those patients with a deficiency in the Achilles tendon. To comply with the above, it is proposed to develop the product from the point of view of four disciplines: biomechanics, ergonomics, eco-design and aesthetics and the incorporation of an orthosis, forming part of the footwear, interchangeably or easily removable due to the union by pins between the heel of the shoe and the orthosis.
    [0043]
    [0044] The union of biomechanics, aesthetics and ergonomics allow the development of footwear that does not only focus on the attractive aspect, like most of these products on the market, but also enhances its functionality, benefiting the patient. The point of view of ecodesign brings sustainability to the development, since the use of completely recyclable materials is considered, a configuration in which each material can be easily separated and does not limit the possible recovery of each element.
    [0045] The interchangeability of the orthosis allows it to be attached to the left or right foot and is removable allowing the user to continue using the shoe when not needed. This configuration also facilitates storage.
    [0046]
    [0047] These are just some of the features and contributions that are intended to be achieved with this invention, but with the use of the invention a series of additional benefits are obtained as set forth below.
    [0048]
    [0049] In the first place, the union between orthosis and shoe as a single element improves the walking experience because, being a set, everything is perfectly positioned and integrated fulfilling its function. This allows the patient to be safe when walking and not worry about discomfort or injuries or fractures when wearing shoes that do not support the Achilles tendon. In addition, the tread is normalized and, therefore, corrected, as well as the posture when walking.
    [0050]
    [0051] In the current market, orthotics and footwear are two products that are sold separately and in which, in many cases, difficulties are found to adapt the first to the second causing the patient to have to buy a higher number or buy specific shoes that They can accommodate the orthosis.
    [0052]
    [0053] With the invention, a single product is achieved that combines the characteristics of the orthoses and footwear that fit perfectly between them and the patient who is using it, so that benefits are acquired that are not obtained with current solutions.
    [0054]
    [0055] Secondly, the geometry of the platform-type sole is studied to improve the game between balancing and flexion during walking. This is achieved by a gradual reduction of the thickness, from the heel to the toe, allowing a degree of inclination in it along with a small arch just below the plantar arch.
    [0056]
    [0057] Some current platform models have a continuous thickness along the entire sole, being often a very large thickness that prevents foot flexion when walking because the materials used in the sole are too rigid and the rolling is It makes it practically impossible if the factors are thick and stiff. With this form, it they end up dragging their feet when walking or overexerting their ankle to lift their shoes.
    [0058]
    [0059] The present invention has focused on developing a sole capable of improving foot play during walking without limiting any movement. With the selected shape, the tread is facilitated and the efforts of the tendons and muscles are reduced, increasing comfort due to its use.
    [0060]
    [0061] Thirdly, the configuration of some strips has been developed so that they travel the width of the sole through an internal lane near the toe and pass through a few second holes further away and then join the orthosis, which allows the shoe is in constant contact, so that impacts, slippage between foot and sole are reduced and comfort during walking is increased. In this way, as the strips are not fixed, they allow a complete adjustment. In a preferred embodiment, the shoe incorporates a single strip, joins the orthosis and, preferably, crosses it several times, hugging the leg and creating a more solid joint of the orthosis to the leg.
    [0062]
    [0063] The joints between the sole and the cut of the footwear are usually made through adhesives or seams that can end up coming off or with the breakage of the cut or the sole, being more common in the case of the former and their repair sometimes if not impossible, it is never completely effective. These problems are avoided with the present invention, in addition to allowing the strips to be replaced with new ones. A complete accommodation of these is also allowed, together with the security that is achieved by keeping the foot in constant contact with the shoe.
    [0064]
    [0065] Fourth, the fact that it is a detachable shoe allows changing the different parts of which it is composed as they wear out or to renew their appearance. Also, storage space is reduced.
    [0066]
    [0067] Fifth, it refuses the use of adhesives and allows the recyclability or reuse of all its parts.
    [0068]
    [0069] The elements of today's shoes tend to be largely bonded with adhesives that limit the possible recycling of parts or the reuse of somewhere. In fact, among the Most commonly used adhesives are polyurethane and polychloroprene adhesives based on organic solvents that are very harmful to the environment, and health workers who assemble these shoes.
    [0070]
    [0071] Due to the problems that can cause footwear adhesives, they have wanted to eliminate the invention and provide a new vision for assembly in footwear.
    [0072]

    [0094] DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION
    [0095]
    [0096] The hybrid product between footwear and removable orthosis for patients with weakness in the Achilles tendon, object of this invention, is based on the development of a Roman style sandal consisting of a sole, a support strap (2) and has integrated orthosis, reinforcing the tendon, which prevents overexertion in it. Due to the above, safety is provided when stepping, so that the tread is normalized, that is, the way of walking, the posture is corrected and the loads are better distributed by that reinforcement in the weakened tendon.
    [0097]
    [0098] The sole is divided into two parts: a front area (1), which extends from the toe to the arch of the foot, and a second area, which covers the entire area of the heel (3), as can be seen in Figure 1 .
    [0099]
    [0100] This sole follows the anatomical shape of the foot, presenting a greater thickness in the part of the heel that is gradually reduced to the toe. In fact, this reduction allows the toe to form an angle of 5-15 degrees with the ground that helps in the rocking during the march as seen in Figure 3. In addition, under the plantar arch a small arch has been added that improves foot flexion
    [0101]
    [0102] On the other hand, the heel (3) is symmetrical, that is, the same piece can be used for the left and right foot interchangeably. This facilitates the manufacturing process and reduces procurement costs.
    [0103]
    [0104] Both parts of the sole are joined through a hole shaft system and will be fixed by a pair of pins (4), preferably made of metal to withstand the required stresses, that cross the heel (3) across. In turn, these pins (4) are those that hold the orthosis, which is composed of two fins (6), one on the outside of the leg, contouring the long lateral peroneum, and another on the inside, going up until it is in the middle of the lower part of the leg.
    [0105]
    [0106] To hold the pins (4) and prevent them from moving, at their ends some covers (5) of the same color as the sole will be adjusted. The covers (5) can also be metallic or, preferably, of plastic material and are fixed in the holes by pressure or by threading.
    [0107] In the upper part of the fin (6) there is a hole for the introduction of a tape (7) that joins the two fins (6). The tape (7) incorporates a closure system and surrounds the leg to ensure superior orthosis to each of the legs. The closure system is preferably of the type with hook and loop closure to allow it to adapt to the legs of different users regardless of size.
    [0108] On the other hand, being the heels (3) symmetrical to allow them to be interchangeable between the two feet, implies that the fins (6), also be symmetrical, to be used interchangeably on any of the legs. There is a possibility that the fins (6) are the same, with the aim of reducing costs, for which they would have to be exchanged according to the foot on which it is intended to be located, loosen them completely and then reattach them to the fin (6).
    [0109]
    [0110] The internal face of the fins (6) of the orthosis, in contact with the user's skin, must be padded (8) to avoid chafing or injury and allow a more comfortable adaptation of the orthosis to the patient.
    [0111]
    [0112] The fastening strip (2), housed in the front area (1) of the shoe, is preferably composed of a single textile elastic strip that first passes through a rail that crosses the sole and covers the width of the front area (1) more above, it is subsequently crossed over the space destined to place the foot on the sole and each of the two ends is passed through two L-shaped holes located further back, opening through the lateral area and the upper area of The sole These L-shaped holes allow the strips (2) to first cross over the contact area between sole and foot and exit the sides of the front of the sole. Finally, the strips (2) are directed towards the fins (6) to pass through other holes located therein, as shown in Figures 2 and 3, hugging the leg, and ends up closing by means of a fixing system known as , for example, a tie knotted or through another hook and loop joint not shown in the figures.
    [0113]
    [0114] Finally, it should be considered that the present invention should not be limited to the embodiment described herein. Other configurations can be made by those skilled in the art in view of the present description. Accordingly, the scope of the invention is defined by the following claims.
