Description

Adjustable fit footwear

technical field

The present invention relates to footwear with adjustable fit, and in particular, to a shoe with adjustable size.

Background technique

Currently, each footwear design is typically produced in a series of generally numerically identifiable standard sizes so that it can be worn by a large number of users with different foot sizes. In particular, for the same shoe design, the different dimensions typically consist of differences in the length and width of the sole and insole and, in addition to certain dimensions, also in the dimensions of the upper on said sole.

Typically, the dimensions vary by one or half units.

The main disadvantage of this known type of footwear is that different devices are required to manufacture different sizes of the same design, which therefore increases the production costs of the footwear.

And, another disadvantage lies in the fact that marketers of such footwear should have stocks of various sizes for each design to satisfy the needs of different customers; this entails high storage costs for the merchant, And need to bear the risk that some sizes do not sell, but at the same time, conversely, other sizes are sold out, so it does not meet the needs of potential consumers.

Yet another disadvantage can also be attributed to said known design types, namely that the same footwear does not include all measurements of the foot, therefore with pre-set dimensions for each size, which forces those with a specific anatomy Structured people need custom footwear.

Contents of the invention

Therefore, the technical problem proposed and solved by the present invention is to overcome the above-mentioned disadvantages.

Within the scope of the above-mentioned problems, another important technical problem solved by the present invention is to realize a shoe whose dimensions can be adapted to the dimensions of the user's feet even if the values vary only within half a size.

Another technical problem solved by the present invention is to adapt optimally to the shape of the user's foot in order to increase its comfort of fit.

Yet another technical problem solved by the present invention is to allow the user to spontaneously and quickly adjust the footwear according to his own specific anatomical needs, without resorting to the intervention of the shoemaker or specific suitable tools.

Therefore, the last (but not the least) technical problem to be solved by the present invention is to devise an invention which is structurally simple and has a reasonable manufacturing cost.

Said problem is solved by a device for adjusting the fit of footwear according to claim 1 , a device for adjusting the length according to claim 12 , and a footwear according to claim 17 . Preferred features of the invention are presented in its dependent claims.

In the context of the present invention, the term "footwear" should be understood in its broadest sense, including any kind of shoes, sandals, slippers, boots, ankle boots, etc., whether for day or night wear, whether for domestic or type of exercise.

The present invention provides several related advantages. The main advantage is to allow adjustment of the footwear to easily suit different foot needs without customization.

Another advantage of the invention is that the adjustment provided by the device according to the invention can be easily applied to any type of footwear, thus ensuring reasonable footwear manufacturing costs.

Detailed ways

In the following exemplary embodiments, respective features described through specific examples may be interchanged with other different features that actually exist in other embodiments.

Referring first to FIGS. 1 and 2 , footwear according to a first embodiment of the present invention is indicated generally at 1 .

As will be described in detail below, the footwear 1 has an adjustable fit, its dimensions are adjustable in length and width, and more generally, it allows changes in the shape properties of the footwear, thereby ensuring the fit of the shape. foot sex.

The shoe 1 includes a vamp 3 and a sole 4 . For greater clarity, the general longitudinal direction of the footwear 1 is identified by the A axis depicted in FIG. 4 .

The sole 4 is connected to an insole indicated generally at 2 and more specifically in FIGS. 3 and 4 .

Referring to the last two figures, the insole 2 comprises a top layer 5 and a bottom layer 6, both of which replicate the sole contour of the foot and are made, for example, of flexible plastic.

The top layer 5 and the bottom layer 6 are connected to each other in their central region by shaped spacer elements or spacers 9 arranged longitudinally relative to the top layer 5 and the bottom layer 6 . The top layer 5 and the bottom layer 6 are connected to the spacer 9 by eg gluing.

The spacer 9 has a substantially laminated configuration and comprises a front region 10 which, in use, partly follows the configuration of the periphery 7 of the top layer 5 and bottom layer 6 beneath the toes of the user. The spacer 9 further comprises a rear region 11 which, in use, partly follows the configuration of the outer periphery 7 of the top layer 5 and bottom layer 6 lying under the user's heel. The front region 10 and the rear region 11 are connected to each other by a middle region 12, which preferably has a width in plan that is shorter than the width of the top layer 5 and bottom layer 6, so that the edge portion 13 on the inside of the foot and the edge portion on the outside of the foot 14 define respective bases 170 .

Obviously, the base 170 can be made according to different embodiments. For example, an insole may be integrally formed by moulding, so that the layers and chassis are defined directly through a suitable mould.

Also, as a further alternative, a first central portion of flexible material (e.g., leather) and a second peripheral portion of plastic material substantially stronger than the first central portion may be used in making the insole, whereby A base 170 is defined. In addition, the peripheral portion has a series of grooves to increase its flexibility. Thus, the peripheral portion may first be made of a rectilinear shape and then folded so as to be provided along the periphery of the middle portion.

This latter embodiment presents a particular advantage, since the peripheral part, which requires greater complexity in handling, can be made in a single form and used in the middle region of different dimensions, which can be easily made of leather.

Still referring to FIGS. 3 and 4 , in this front region 10 , preferably at its periphery, a second seat 15 is provided, which in plan has an arched profile following the configuration of the adjoining outer periphery 7 . Preferably, as shown in the figures, this second seat 15 may be defined by a first recess provided on the top surface of the front area 10 . Alternatively, the second base 15 may consist of at least one first (through) hole (not shown).

In the rear region 11 of the spacer 9 there are two third seats 16 arranged according to mutually parallel and longitudinal axes, preferably on opposite sides of the middle region 12 . Preferably, as shown in the figures, the third bases 16 may be respectively defined by two second grooves provided on the top surface of the rear region 11 . Alternatively, the third base 16 may consist of two second (through) holes (not shown) arranged longitudinally to the rear area 11 .

As mentioned above, layers 5 and 6 face each other and are spaced apart by an intermediate region 12 therebetween. In general, the spacing involves at least one length or part of the perimeter 7 of the layers 5 and 6 to slidably accommodate a plurality of movable support elements 8 inside the base 170 for easy supportable receipt of the sole of the foot. These movable support elements 8 can be arranged sequentially along the circumference 7 of said insole 2 , between the front area 10 and the rear area 11 of the spacer 9 .

The support element 8 preferably has a substantially rectangular arrangement in plan and the sides are shaped to follow the configuration of the peripheries 7 of the adjoining top layer 5 and bottom layer 6 . And the corners are rounded to facilitate the mutual movement of the support elements 8 and the movement of the support elements 8 with respect to the front area 10 and the rear area 11 of the spacer 9 on the plane defined by the bottom layer 6 and the top layer 5 .

Preferably, a third seat 17 is provided longitudinally to said support element 8, being identical along its entire length.

As shown, the third base 17 can be arranged on the top surface of the supporting element 8 , or can consist of a through-hole (not shown) longitudinally arranged in the supporting element 8 .

The support elements 8 are connected to each other by traction elements 18, which in this embodiment consist of nooses made of, for example, metal, which are inserted and fixed in the third seat 17 of the support elements 8 by gluing or pressing and In the first seat 15 of the front area 10 of the spacer 9 . The two longitudinal edges of the noose 18 are slidably associated with a second seat 16 in the rear area 11 of the spacer 9 and are connected to adjustment means for adjusting the tension of the noose 18 itself. In the present embodiment, the adjusting means consist of adjusting screws 19 secured at their own threaded shanks to the ends of the noose 18 and rotatable in internally threaded holes 20 which allow Located eg in the rear region 11 of the spacer 9 , as shown in FIG. 5 .

As will be better understood below, by adjusting the tension of the traction elements 18, support elements 8 can be enlarged or retracted to a desired length peripherally (radially) relative to the top layer 5 and bottom layer 6 .

As shown in FIG. 6 , the upper 3 is at least partially fixed under one or more supporting elements 8 at its bottom periphery.

As also shown in FIGS. 10 and 11 , the upper 3 is composed of a front part 21 and a rear part 22 , which are connected to each other by elastic means 27 which will be described in detail below.

In use, the front portion 21 covers from the toes to about the instep of the user's foot. At its bottom periphery this front part 21 is fixed to the bottom surface of the support element 8 by eg gluing or sewing, and it is also fixed to the front area 10 of the spacer 9 .

The front part 21 of the upper 3 extends oppositely to the front region 10 of the spacer 9 , with two substantially parallel arms 26 joined to the rear part 22 of the upper 3 by means of said elastic means 27 .

In use, rear portion 22 of upper 3 covers the user's heel and ankle and is integrally connected to heel 23 which is slidably constrained to insole 2, as will be described in more detail below.

Preferably, the rear portion 22 is constructed of a thin layer 24 , typically of leather or fabric, which is folded upon itself in a substantially "U" shape to define a housing 25 . Of course, in use, this folded sheet is in plan, in the area protruding from the user's heel, a contour extending along the outer periphery 7 of the top part 5 and bottom part 6 .

The arms 26 of the front part 21 of the upper 3 are slidably housed in the frame 25 and interconnected by said elastic means 27, which in this embodiment are arranged in the heel and consist of elastic strips, This elastic strip is slidably housed in the frame 25 and secured at the end of said arm 26 .

The elastic deformation of the strip 27 and the configuration described here make it possible to protrude the arm 26 from the frame 25 by a desired length, but at the same time always keep the front part 21 and the rear part 22 of the upper 3 in mutual restraint.

The rear portion 22 of the upper 3 is secured to the heel 23 by, for example, sewing or gluing its bottom periphery to the side 28 of the heel 23 .

The rear portion 22 of the upper 3 has two through openings 35 at the adjusting screws 19 to allow the user to operate said screws and thereby adjust the tension of the noose 18 .

The heel 23 is slidably constrained to the bottom layer 6 of the insole 2 by means of illustrated attachment means (eg FIGS. 7, 8 and 9). In the present embodiment, the connection means comprise a block element 29 having a substantially trapezoidal or wedge-shaped configuration in cross-section and fixed to the same base layer 6 by known means, such as screw gluing. This block element 29 is slidable in the hole 30 of the heel 23 and partially engages said block 32 to maintain the compression of it by the heel 23 . Of course, various embodiments may provide different kinds of shapes for the connection between the heel and the insole-connecting element.

In addition, an adjusting device for adjusting the relative position of the heel 23 and the insole 2 is provided. In the embodiment shown in the figure, the adjusting device is composed of The shape consists of a first rack 31 fixed to the bottom surface of the block element 29 and a second rack 32 meshing with the first rack 31 and fixed to the inner surface 33 of the openable part 34 at the bottom of the heel 23 .

Said openable part 34 is hingedly connected to a fixed part 36 of the heel 23, and the openable part 34 acts as a cover for the hole 30, snapping it into place in a known manner to close said hole.

The sole 4 is then fixed to the bottom layer 6 of the insole 2 in the area of the insole 2 not reaching the heel 23, for example by gluing or sewing.

Hereinafter, the operation of the shoe 1 will be described with reference to the drawings.

Firstly, the heel 23 , which is slidably arranged relative to the insole 2 , allows the adjustment of the length of the shoe 1 , for example its size. In particular, by opening the openable portion 34 of the heel 23, the engagement between the first rack 31 and the second rack 32 can be removed, so that the heel 23 and the second rack of the upper 3 can slide relative to the insole 2. part 22, thereby positioning the second part 22 at a desired distance from the first part 21. When the desired position is reached, the openable part 34 is closed, thereby re-engaging the first and second racks 31 and 32, thereby achieving the blocking of the front part 21 of the upper against the rear part 22 and obtaining the desired length of footwear 1.

In addition, adjustment of the fit or rigidity of the sides of the shoe 1 can also be achieved by operating the associated means implemented by the support element 8 and its associated components. In particular, by operating the adjusting screw 19 , it is possible to adjust the tension of the noose 18 , thereby increasing or decreasing the mobility of the support element 8 and ensuring that this support element 8 protrudes peripherally from the insole 2 by a desired length. When the foot enters the upper 3, pressure can be applied to the upper 3, whereby the upper 3 deforms and pulls one or more support elements 8 fixed to the insole 2 towards the outside of the insole 2; Thus, the upper 3 and the insole 2 can be adapted to the shape and dimensions of the user's foot, thereby increasing comfort.

Therefore, it is easy to understand that the footwear according to the invention can be optimally adjusted to the shape of the user's foot due to the fact that part of the upper is fixed to the support element, and can be worn by people with abnormal foot shapes, who often require custom-made shoes Tool.

In addition, it is readily understood that the length and fit/stiffness adjustments are completely independent and therefore operate separately from each other.

The footwear described allows for adjustment of the dimensions in length and width, and thus the fit in general, so as to cover a number of common sizes of known footwear.

The production costs of the footwear according to the invention remain moderate and it can be made entirely of components that are easy to produce and/or assemble.

It will be readily understood that the invention is also optimally suited to making sports shoes of different stiffnesses required for the respective actual sporting practice and everyday use. In this case, the option to adjust the fit of the footwear may provide optimal options for achieving different stiffnesses.

It will be readily understood that the present invention allows various alternatives to the embodiments described herein, some of which will be briefly described below with reference to those aspects that differ from the first embodiment.

According to a variant, it is possible to produce a shoe whose insole is not attached to the upper, but to one or more straps and/or strips and/or nooses, and through their The medial side and the lateral side of the foot are respectively fastened under the insole support element. In use, the strap and/or strip and/or noose serves to at least partially enclose the user's foot, constraining it to the insole, thereby allowing the creation of slippers or sandals whose dimensions can be continuously changed by the user , to optimally adjust it to the shape of the user's foot.

In addition, as mentioned above, the footwear is preferably used in the manufacture of sports footwear such as ski or skateboard boots, football boots, cycling shoes, hiking boots, ice skates and the like.

Of course, the materials used and the dimensions of the components making up the footwear can be selected according to specific requirements.

Another embodiment of the present invention is shown in Figures 12-21. Hereinafter, another embodiment will be described in conjunction with aspects that differ from the described embodiment and modifications thereof. In addition, the same parts will bear the same references as already described.

With reference to said figures, the footwear in this case is generally designated 100, comprising an insole (here designated 200) consisting of a top layer 5, a bottom layer 6 and spacers ( Here with 90 mark) composition. Said spacer 90 essentially replicates the shape of the sole of the foot, except for two peripheral longitudinal portions, which are defined in the medial portion 13 and lateral portion 14 of the foot, and, with reference to FIG. 5. The bottom layer 6 and the spacer 90 are formed. This base 170 then extends into another pair of bases 171 which, as shown in FIG. Said bases 170 and 171 slidably accommodate a traction element (here designated 180 ), which is a flexible protruding element on which is slidably inserted an annular or tubular support element 80 . In addition, traction element 180 is fixed to insole 200 , more precisely at its front end to spacer 90 .

The longitudinal ends of the element 180 are blocked in a stop 40 which is slidably received in the longitudinal recess 160 of the spacer 90 . The blocking is achieved in a conventional manner by inserting said tip into the hole of the blocking member and being held in place by a threaded pin 41 .

The stopper 40 is operated by the screw 190 being held back against the stopper 40 at the end of its shank, and the stopper 40 is slidable in a threaded seat 161 between the recess 160 and the rear periphery of the spacer 90 extended.

The integral arrangement allows the screw 190 to be accessible from the rear of the footwear 100 at the heel. It is easy to understand that, by turning the screw 190, the blocking member 40, together with the traction element 180 integrated therewith, can slide longitudinally in the recess 160, i.e., relative to the insole 200, relative to the base 170, along the element 80, defining the traction element 180, as shown in Figure 14. In other words, following the longitudinal adjustment of the block 40 into the recess 160, the traction element 180 is moved, sliding inwards or outwards respectively from the insole into the base 170, thereby adjusting the directional position of the base 170 relative to the insole.

It will be readily appreciated that in this embodiment a dual level of adjustment of the fit or stiffness of the footwear may be achieved, for example, through a suitable opening on the top layer 5 of the insole 200 operable stop 40 . In fact, in the first case, the initial tension of the element 180 can be adjusted by adjusting the depth of penetration, and optionally by adjusting the depth by which the longitudinal ends protrude into/from the corresponding hole into the stop, for example as Figure 15 shows.

Additionally, the tension can be further adjusted by routinely manipulating screw 190 .

Another difference of this second embodiment with respect to the first is the way in which the front part 21 of the upper 3 is blocked to the traction elements. In fact, as shown in FIG. 16 , instead of being fixed directly to the support element 80 , said part 21 is partly looped over the support element 80 and, in particular, is folded at its rear, and then in the part marked by 210 , Stop on the bottom surface of the bottom layer 6 of the insole 200 . Thus, the overall arrangement is shown in FIG. 18 , whereby the upper retracts within the seat 170 to a greater or lesser extent, depending on the tension of the element 180 . Of course, the base 170 may be suitably dimensioned so as to allow the upper 21 to be accommodated in the aforementioned manner and to allow sufficient possibility of lateral movement of the element 180 .

Thus, by providing a footwear with a greater amount of upper, this feature allows adjustment of the fit so that, by the natural softness and flexibility of the upper itself, the foot can be adapted to the shape properties of the shoe according to the specific needs of the user. .

In this embodiment, the footwear is also provided with a conventional lining 45 secured to the sole 4 to allow modification of the seat 170 and traction elements 180 .

According to a variant embodiment, the traction element 180 may also not be associated with the support element 80 connected thereto. In this case, on the other hand, the support element has the sole function of facilitating the sliding of the upper, in adjusting the fit by the movement of the traction elements, thus preventing wear of the upper 3 itself. Accordingly, the support element 80 may be replaced by a single sheath of plastic material (not shown) to facilitate limiting friction during said movement.

It should be understood that various means for carrying out specific different functions are of course present not only in the described embodiments but also in other not described embodiments.

The present invention has been described above through preferred embodiments. It is easy to understand that there are other embodiments embodying the gist of the present invention, all of which should fall within the protection scope of the appended claims.
