Description

COMPOSITE SHOE WITH REMOVABLE ARCH SUPPORT
DESCRIPTION
The present patent relates to shoes with removable arch support and in particular concerns a new composite shoe with removable arch support. Orthopaedic shoes are known that are adopted by users who suffer from various pathologies of the foot, for example malformations of the sole area, callosity or bursitis or other.
Shoes are known comprising customised arch support and self-modelling upper, which adapts to the form of the foot without compressing it.
Shoes are known with removable arch support, suitable for replacement with customised orthosis according to the pathologies of the user.
Said orthopaedic shoes with removable arch support of the known type comprise a tread sole made of polyurethane or another generally synthetic material, on which an upper is assembled or sewn, according to various possible techniques.
Said sole is internally hollowed out to define a seat that is suitable for the removable insertion of an arch support.
Said arch support can therefore be easily taken out and can be removed and replaced as necessary with a different arch support or with a customised foot orthosis.
The removable arch supports of known type can be made of cork, cork and latex, polyurethane or other materials.
Said removable arch supports can be mass-produced or made to measure and customised according to the patient's needs.
Shoes of the so-called "Bio" type are also known, comprising an arch support consisting of a mixture of latex and cork. These shoes, however, which are very popular thanks to their lightness and comfort, do not allow the insertion of removable and replaceable foot orthoses, since they do not have a seat suitable for containing a removable arch support and furthermore their structure is not sufficiently rigid and robust to house the orthosis.
The subject of the present patent is a new type of composite orthopaedic shoe, with shaped reinforced assembly arch support, removable arch support or orthosis, integrated upper and tread.
The main object of the present invention is to mass-produce the various components of the shoe for subsequent assembly, so as to maximise the variety and versatility of the possible shoe models according to user requirements.
A further object of the present invention is to guarantee maximum user comfort.
For said purpose, the surface where the foot rests is continuous and uniform, without sharp edges and irregularities, due to particular characteristics described and claimed below.
These and further direct and complementary objects are achieved by the new composite orthopaedic shoe, comprising in its main parts: at least one sole having the function of a wedge or wedge and tread, at least one hollow arch support, shaped and reinforced to house a removable arch support or a foot orthosis, said insole being suitable for being joined to said sole, and an upper connected in any way to said insole and/or to said sole.
In particular, said sole is made of rubber and/or other materials such as polyurethane, leather, etc.
Said sole can be shaped to act as a wedge and tread.
Alternatively, said sole acts as a wedge, made of rubber or another material like polyurethane, EVA, etc., and can be coupled to a further tread made of a suitable material and appropriately shaped, with lug sole below.
The shoe furthermore comprises said hollow arch support, suitable for connection in any way to said sole, for example by means of gluing, sewing or another technique.
Said hollow arch support is preferably made of latex and cork, and/or other materials or combinations of materials, for example polyurethane and cork, rubber and cork, synthetic mixtures, microporous rubber or other.
Said hollow arch support comprises a seat for removable arch support or foot orthosis and in particular it comprises a substantially flat lower surface for coupling with said sole, while the upper surface is hollowed out to provide said seat, delimited by raised perimeter edges.
Said insole is reinforced at least at the level of the bottom of said seat, preferably with at least one reinforcing net made, for example, of a cotton- synthetic mixture or entirely of plastic.
Alternatively or in combination with said net, said insole can comprise a layer made of leather or another reinforcing material, in order to make the insole mixture more compact and robust.
Said reinforcing net or layer is buried in the thickness of said hollow arch support or is connected to it in any way.
Said bottom of the seat is furthermore preferably shaped with one or more further lowered parts, or supporting sections, for example a supporting section at the level or in the vicinity of the front part or toe and a further supporting section in the vicinity of the rear part or heel, suitable for housing inserts for removably fixing said removable arch support or orthosis.
Said inserts can be made of Velcro or adhesive material, for example.
Said inserts are fully housed within the thickness of said supporting sections. In this way, said seat has a surface for resting the removable arch support or orthosis which is as uniform as possible, thus guaranteeing stability of the removable arch support and therefore stability during walking.
The raised edges of the hollow arch support, which delimit said seat, are preferably shaped so that they are perfectly joined to the upper surface of the removable arch support or orthosis, for example slanting down towards the inside.
In this way, the upper surface of the hollow arch support with removable arch support or orthosis inserted therein is uniform, without sharp edges.
Said hollow arch support and said sole have any height, according to the model of shoe to be produced, guaranteeing great versatility.
Said hollow arch support can be covered wholly or partly with part of the upper or with inserts made of any type of material, leather or other. Said hollow arch support can furthermore be spray coloured or coloured by means of any other technique.
Said removable arch support or orthosis is suitable for insertion in said seat and therefore has, in plan view, shape and size corresponding to the shape and size of the seat in plan view.
Said removable arch support or orthosis is customised according to the patient's needs and is suitable for being covered with any suitable material, natural and/or synthetic, for example leather, cork, micro fibre or other. Said shoe also comprises the upper which can be made of any material suitable for the purpose and is preferably constrained between said sole and said hollow arch support, therefore enveloping at least partially said hollow arch support.
Alternatively said upper is assembled on the outside, for example sewn, glued or connected in any way to said sole.
The characteristics of the new shoe will be better clarified by the following description with reference to the drawings attached by way of non-limiting example.
Figure 1 shows a schematic exploded view of the new shoe (1).
Figure la shows a section of the exploded view along the line of section A- A.
Figures 2 and 3 show a plan view of a hollow arch support (3) and a removable arch support (4), respectively.
Figure 4 shows a lateral view of the new shoe (1) with upper (5).
A new composite orthopaedic shoe (1) is described, of the type with removable arch support (4).
The new shoe (1) comprises at least one sole (2), having the function of a wedge or, preferably, wedge and tread, that is, comprising an upper surface (21) and an opposite lower surface (22) shaped for contact with the ground. The new shoe also comprises at least one hollow arch support (3) suitable for being joined to the upper surface (21) of said sole (2), for example by means of gluing, sewing or another technique.
Said hollow arch support (3) comprises a substantially flat lower surface (31) for coupling with said upper surface (21) of said sole (2), while the upper surface (32) is hollowed out to obtain a seat (6) delimited by raised perimeter edges (34).
Said seat (6) is suitable for the insertion of a removable arch support (4) or foot orthosis.
Said hollow arch support (3) is reinforced at least at the level of the bottom (61) of said seat (6). For said purpose, said hollow arch support (3) comprises for example at least one reinforcing net (33) or reinforcing layer, in order to make the mixture used for the production of said hollow arch support (3) more compact and robust.
Said reinforcing net or layer (33) is for example buried within the thickness of said hollow arch support (3).
On said bottom (61) of said seat (6) one or more further lowered parts or supporting sections are obtained.
In one possible preferred embodiment of the invention, said hollow arch support (3) comprises at least one supporting section (62) at the level or in the vicinity of the front part or toe (11) and a further supporting section (63) in the vicinity of the rear part or heel (12).
Said inserts (62, 63) are suitable for housing within their thickness inserts for removably fixing an insole (4) or removable orthosis, made of Velcro or an adhesive material, for example.
The new shoe also comprises at least one removable arch support (4) or orthosis suitable for insertion in said seat (6) of the hollow arch support (3), that is, having, in plan view, shape and size corresponding to the shape and size of said seat (6) in plan view, as schematically shown in Figures 1 , 2 and 3.
Said removable arch support (4) has a substantially flat lower surface (41), for resting on said bottom (61) of the seat, and an upper surface (42) shaped with reliefs and/or depressions (45) according to user needs.
Seats, gaps or slots (44) can be provided on said removable arch support (4) for the insertion of parts of the upper (5), for example for flip-flop shoes.
The height of said removable arch support or orthosis (4) corresponds to the height of said seat (6), so that at least the perimeter part (43) of the upper surface (42) of said removable arch support (4) is substantially flush with said raised edges (34) of said hollow arch support (3), which delimit said seat (6).
In particular, the upper surface (35) of said raised edges (34) of said hollow arch support (3) is joined to said perimeter part (43) of said upper surface (42), for example slanting down towards the inside.
Said new shoe (1) also comprises an upper (5) preferably connected between said sole (2) and said hollow arch support (3), therefore enveloping at least partially said hollow arch support (3).
Alternatively, said upper (5) is assembled on the outside, for example sewn, glued or connected in any way to said sole (2) and/or to said hollow arch support (3).
Therefore with reference to the preceding description and the attached drawings, the following claims are expressed.
