Description

Orthopedic piece, orthopedic midsole with same and orthopedic shoe

Technical Field

The invention relates to the field of shoemaking, in particular to the field of orthopedic shoes, and particularly relates to an orthopedic piece for a midsole, an orthopedic midsole with the orthopedic piece and an orthopedic shoe with the orthopedic midsole.

Background

The sole of the shoe is generally a multi-layer structure, comprising three layers, namely an outsole, a midsole and an insole, from outside to inside, wherein the three layers have different functions, and the sole structure of the orthopedic shoe on the market is different according to different foot shapes needing to be corrected. For example, there is an orthopedic shoe for correcting the shape of a forefoot, in which a cushion is provided on the upper surface of a midsole, the cushion corresponding to an arch region of the sole (or corresponding to a medial portion of the heel), and the cushion of the orthopedic shoe is capable of correcting the shape of the foot arch region of a user's foot when the user walks or runs, because the user suffering from the forefoot has a foot in which navicular bone of the foot is sunk to cause collapse of the arch. Because the foot arch collapse degree of users with pronation is different, in theory, cushion blocks with different heights are needed for carrying out the rectification, but the height of the cushion block of the traditional rectification shoes is usually standard, so that when some users with pronation wear the rectification shoes, the height of the cushion block of the rectification shoes is not completely suitable for the foot shape, if the height of the cushion block is too high, the user's foot arch is easy to be pressed upwards, the foot is pressed against, and if the height is too low, the user's foot arch collapse cannot be carried out upwards, and the rectification effect is poor.

Disclosure of Invention

The technical problem to be solved by the invention is to provide an orthopedic piece for a midsole, an orthopedic midsole with the orthopedic piece and an orthopedic shoe with the orthopedic midsole, so that a user with pronation is not easy to press against feet when wearing the orthopedic shoe, and the orthopedic effect is good.

The inventor researches find that although the collapse degree of foot arches of different pronating foot patients is different, the front plantar region of the sole, particularly the first plantar toe region, is not greatly different; the inventor also found that when the user lands on the sole, if the first plantar toe area of the sole is jacked up, the foot can be correspondingly lifted, and the arch area can be lifted up as well, so that the orthopedic effect is achieved.

Based on the above findings, the present invention provides an orthotic for a midsole comprising a wedge-shaped body mountable on an upper surface of the midsole with a medial portion thicker than a lateral portion, corresponding to a first metatarsophalangeal region of a forefoot region of the sole.

Further, the wedge-shaped body is flat or arched upwards.

Further, the thickness of the wedge-shaped body is 2-5 mm, and/or the hardness of the wedge-shaped body is 80-85 HA.

Further, the wedge-shaped body is partially hollowed out.

Further, a flanging which can be blocked on the inner side of the midsole extends out of the inner side part of the wedge-shaped body.

Further, the flanging tail end extends inwards to form an extension part.

The invention also provides an orthopedic midsole comprising a midsole body, wherein the upper surface of the midsole body is provided with the orthopedic piece.

Further, the upper surface of the midsole body is provided with a pit, the orthopedic piece is accommodated in the pit, and the edge of the orthopedic piece is in smooth transition with the upper surface of the midsole body.

Further, as described above, the medial bottom of the midsole extends inwardly below the flange of the orthopedic, and the flange end extends inwardly to form an extension that covers the side flange.

The invention also provides an orthopedic shoe comprising a midsole, the midsole being as described above.

The beneficial effects are that: the upper surface of the orthopedic midsole of the orthopedic shoe is provided with an orthopedic piece, the orthopedic piece corresponds to a first plantar toe area of a plantar front plantar region, when a patient wears the orthopedic shoe to walk or run, the first plantar toe area of the foot is trampled on the orthopedic piece when the foot falls to the ground and is jacked by the orthopedic piece, and the front part and the inner side part of the foot are driven to be lifted upwards when the first plantar toe area is jacked, so that the plantar arch area is driven to be lifted to realize the orthopedic; as the first plantar toe areas of the soles of different pronation foot patients are basically the same and can tread on the orthopedic piece when walking or running, the orthopedic piece is jacked up by the orthopedic piece and can drive the plantar arch areas to lift up to realize the orthopedic, the orthopedic piece can have better orthopedic effect no matter how the collapse degree of the foot arch of the patient is. The orthopedic piece is wedge-shaped, and its medial part is thicker than outside portion, and partial strength is unloaded when user's plantar steps on the wedge-shaped surface, is difficult to hard to land, so be difficult to press against the foot.

Detailed Description

The invention is further described in detail below in connection with the detailed description.

The orthopedic shoe sole comprises an outsole, an orthopedic midsole and an insole which are arranged from outside to inside, wherein the structure and principle of the outsole and the insole are conventional technology, and are not repeated herein. Referring to fig. 1, the orthopedic midsole 1 includes a midsole body 11 that is contoured to a human sole 3 (see fig. 2), the midsole body 11 is manufactured by a foaming process, a hardness measurement is performed on the midsole body 11 by a C-type shore durometer, and the hardness of the midsole body 11 is measured to be 50-53 HC.

Referring to fig. 3, the midsole body 11 has a recess 12 (see fig. 4) formed in the upper surface thereof, and the orthotic member 2 is mounted over the midsole body 11 and received in the recess 12 in correspondence with the first metatarsophalangeal region 311 in the forefoot region 31 of the human sole 3. The orthopedic component 2 has a wedge-shaped body 21 with a thickness of 2-5 mm, and an inner side 211 is thicker than an outer side 212; the inner side 211 of the wedge-shaped body 21 of the orthosis 2 is downwardly extended with a flange 22 (see fig. 6), the flange 22 being blocked against the inner side 112 of the midsole body 11 after the orthosis 2 is mounted to the upper surface of the midsole body 11; the bottom of the medial side 112 of the midsole extends inwardly below the flange 22 of the orthotic 2 with a lateral projection 111, and the distal end of the flange 22 extends inwardly to form an extension that covers the lateral projection 111. Referring to fig. 4, the edge (the front edge and the outer edge in this embodiment) of the wedge-shaped body 21 is smoothly transited to the upper surface of the midsole body 11, and there is no significant level difference between the edge and the upper surface. The orthopedic piece 2 is a plastic piece, the hardness of the orthopedic piece 2 is measured by using an A-type Shore hardness meter, and the hardness of the orthopedic piece 2 is measured to be 80-85 HA (degree). In this embodiment, the wedge-shaped body 21 of the orthosis 2 is plate-shaped. In other embodiments, the wedge-shaped body 21 of the orthosis 2 can instead be slightly upwardly arched. In addition, in this embodiment, after the orthopedic component 2 is accommodated in the pit 12 of the midsole body 11, the flange 22 thereof plays a role in auxiliary limiting and auxiliary fixing. It is not preferable that the orthopedic member 2 is not provided with the flange 22, the middle sole body 11 is not provided with the concave pit 12, and instead, the orthopedic member 2 is directly fixed on the upper surface of the middle sole body 11 in an adhesive manner for installation, but the orthopedic member 2 cannot play an auxiliary limiting role in the process of fixing and installing because of the lack of the flange 22.

Referring to fig. 5, the posterior portion of the orthopedic component 2 is integrally formed with a guide 4, the guide 4 being of the same material and hardness as the orthopedic component 2. Referring to fig. 3, the posterior portion 41 of the guide 4 corresponds to the lateral region 33 of the human sole 3 and the anterior portion 42 corresponds to the medial portion of the anterior plantar region 31 of the human sole 3, with the anterior portion 42 being connected to the posterior portion of the wedge-shaped body 21 of the orthotic 2. In other embodiments, the guide 4 and the orthosis 2 can instead be split.

A user with a pronated foot wears the shoe to walk or run, with the heel area 32 of the sole 3 first falling to the ground and stepping on the rear portion of the midsole body 11; after the heel region 32 of the sole 3 lands, the sole 3 outer side region 33 and the front plantar region 31 land in turn, and under normal conditions, the arch region 34 of the sole 3 in the process is almost suspended and does not land, but the arch region 34 of a user with the pronated foot is collapsed, and the situation of landing exists when the collapse is serious, but no matter whether the arch region 34 lands or not, the sole 3 outer side region 33 and the inner side part of the front plantar region 31 of the sole 3 (particularly the first plantar toe region 311 of the front plantar region 31 of the sole 3) are mainly stressed parts, and the hardness of the guide piece 4 corresponding to the mainly stressed parts is higher than that of the middle sole body 11, so that a better supporting force can be provided for the main stressed parts of the sole 3 outer side region 33 and the front plantar region 31 in the process of the sole 3 in turn, the user is not easy to break the foot, the damage to the foot of the user is not easy, and the safety is ensured. Since the middle sole body 11 is provided with the orthopedic piece 2, which corresponds to the first metatarsophalangeal region 311 of the front metatarsophalangeal region 31 of the sole 3, when the front metatarsophalangeal region 31 of the sole 3 falls to the ground, the first metatarsophalangeal region 311 serving as a main stress part is trampled on the orthopedic piece 2 and can be jacked up by the orthopedic piece 2, and the first metatarsophalangeal region 311 is jacked up to drive the inner side part of the foot to be lifted up, so that the arch region 34 of the sole 3 positioned at the inner side part of the foot is lifted up to realize the orthopedic. Although the foot 3 arch region 34 of different pronated foot patients collapse to different extents, the first metatarsophalangeal region 311 of the foot 3 is substantially the same and can tread on the orthopedic member 2 during walking or running, so that the first metatarsophalangeal region 311 can be jacked by the orthopedic member 2 to drive the foot 3 arch region 34 of the inner side of the foot to be lifted for realizing the orthopedic effect, and the orthopedic effect is not influenced by the collapse condition of the foot arch region 34 of each person. In addition, the guide 4, while providing a better support for the main stress areas of both the lateral zone 33 and the anterior plantar zone 31 of the sole 3, will also guide the partial pressure of the main stress areas to the first metatarsophalangeal zone 311 of the anterior plantar zone 31 of the sole 3. The wedge-shaped body 21 of the orthopedic component 2 has the inner side 211 thicker than the outer side 212, so that partial force is removed when the first metatarsophalangeal region 311 of the sole 3 serving as a main stress part of a user steps on the wedge-shaped surface of the wedge-shaped body 21, the foot is hard to touch and is not easy to touch; the wedge-shaped body 21 has a certain hardness, and on this basis, as shown in fig. 5 and 6, the wedge-shaped body 21 of the orthopedic component 2 is partially hollowed out 23, so that the wedge-shaped body 21 can be sunk and deformed when being pressed too much, thereby further avoiding the first metatarsophalangeal region 311 of the user from being hard to land, and making the sole 3 of the user more comfortable when falling to the ground.

The above-described embodiments are provided for the present invention only and are not intended to limit the scope of patent protection. Insubstantial changes and substitutions can be made by one skilled in the art in light of the teachings of the invention, as yet fall within the scope of the claims.
