Description

The present invention relates to a hosiery.

The invention is used in the clothing sector.

At present, articles of clothing are known and widespread, and are adapted to cover and cover the limbs and hands and feet of the human body.

Among these products are hosiery, which, among others, include: stockings, socks and tights.

A hosiery, such as a sock, typically covers the wearer's foot up to the ankle, but may extend down to the bottom of the knee.

Usually such a hosiery is located between the foot and the boot.

One of the purposes of the hosiery is to absorb the sweat produced by the sweat glands, which are present in large quantities, especially in the part of the foot near the forefoot.

However, the sweat-absorbing capacity of the textile material from which the hosiery is made is not unlimited.

For this reason, the hosiery becomes wet for a short time, causing the wearer to experience an unpleasant feeling of dampness and coldness, which creates discomfort.

In addition, when the textile material of which the hosiery is made becomes wet, the coefficient of friction between the hosiery and the insole of the shoe increases and may exceed the coefficient of friction between the hosiery and the skin of the wearer's foot.

As a consequence, shear stresses may develop which act on the wearer's foot to determine movement of the foot relative to the hosiery, instead of allowing the foot and hosiery to move simultaneously.

This phenomenon causes the formation of abrasions of the foot and ruptures of the skin of the foot.

In addition, the evaporation of sweat can be significantly slowed down when the foot is in the boot, and in particular when the breathability of the boot is poor or negligible.

Therefore, it is necessary to look for solutions that would facilitate ventilation between the hosiery and the boot, in order to allow sweat to escape in the vapor phase and thus reduce the likelihood of steam condensing inside the boot, inevitably impregnating the hosiery.

Another purpose of the hosiery is to provide support, in particular for the sole of the foot, on which the weight of the human body rests, which also exerts pressure on the hosiery due to its movement.

In fact, typically, the articles of clothing that the consumer wears interact with the human body, for example, exerting contact pressure at every point where there is contact between the articles and the human body.

Such contact pressure occurs, for example, due to the weight of the garments themselves and due to the tension of the textile materials from which they are made.

The contact pressure between the hosiery and the foot of the user who wears it takes on a different value according to the considered part of the foot.

In fact, it is known that under static conditions, the foot usually has three points of support:

- rear fixed support attributable to the calcaneus;

- anterior-lateral support attributable to the head of the fifth metatarsal bone;

- antero-medial support attributable to the head of the first metatarsal bone and sesamoid bones.

These three points of support define three different plantar arches:

- anterior arch formed by the five heads of the metatarsal bones;

- lateral longitudinal arch, between the calcaneus and the head of the fifth metatarsal bone;

- a medial longitudinal arch formed in such a way that it passes in the direction from the back of the foot to the forefoot through the calcaneus, talus, navicular, first cuneiform bone of the foot and first metatarsal bone.

During movement, when placing the foot on the ground, the following three phases take place:

- the first phase in which the back of the heel comes into contact with the ground, called "taligrade time";

- the second phase - support on the heels, front and back, and on the lateral edge of the foot, called "plantigrade time";

- the third phase - support only on the forefoot, with a gradual weakening of the support on the heads of the metatarsal bone from the outside - inside, called "digitigrade time".

In general, both in the static state and in movement, in the medial part, the foot rests mainly on the lateral surface of the foot, while the medial surface of the foot is only minimally involved.

Thus, it is necessary that garments are also adapted to effectively and comfortably cover the human body, for example, that they are not crushed under the weight of the human body or sagging, for example, under their own weight, or, indeed, not excessively wrinkled. in some places, for example, in areas of limited places of the foot of the foot, causing pain or discomfort to the user.

These necessary conditions are particularly important for hosiery, which are predominantly in direct contact with the wearer's skin and have a significant impact on the comfort experienced by the wearer.

In view of the above, there is a real need to create a hosiery that would facilitate the removal of warm air and sweat in the vapor phase from the interior of the boot to the outside, while looking for solutions related to the detection and elimination of places of steam condensation, and providing an adequate level foot supports.

It should be noted, however, that the needs indicated above occur simultaneously, but to varying degrees in different areas of the foot.

There is thus also a need to provide hosiery designed to meet these needs in a variety of ways in different areas of the foot.

US 7,614,257 discloses ideas for solving the problems of removing moist air escaping from the interior of a hosiery and allowing outside air to enter by providing a hosiery in which:

- the part corresponding to the foot of the foot contains the first ridges, located according to a predetermined direction;

- the part corresponding to the instep of the foot contains the second ridges, similar to the first ridges, but directed along the longitudinal extent of the hosiery.

The first and second ridges essentially define the channels through which air and sweat in the vapor phase pass.

Air and sweat in the vapor phase which enter from the channels formed by using the first ridges arrive in the channels formed by the use of the second ridges and can thus exit the boot.

Outside air enters the boot and hosiery along the same route as sweat in the vapor phase, but in the opposite direction.

This well-known solution has a number of disadvantages.

In the disclosed hosiery, there are virtually no ridges and channels, for example, in part of the plantar arch.

As a result of this, the irregularly correct movement of sweat in the vapor phase can occur in such a part, followed by condensation.

In addition, this patent document embodies the ideas of transporting sweat in the vapor phase to a part of the plantar arch, starting in particular from the part located immediately behind the toes: this route is longer than the route leading to the inside and outside of the foot, such thus increasing the risk of condensation.

US 5319807 discloses ideas for creating a hosiery containing:

- a multilayer panel located in the instep area;

- layers of thinner textile material than the panel, located on opposite sides of the multilayer panel, to form ventilation channels.

Essentially, the channels are defined by the difference in thickness of the textile material used in the different zones.

However, this known method also has a number of disadvantages.

In the hosiery described in this document, there are no channels in the area of the foot; thus, in this part the ventilation is not improved to any extent.

US 5,708,985 discloses ideas for a hosiery in which the portion in contact with the sole of the foot has ridges extending transversely with respect to the direction of extension of the product and spaced longitudinally.

These ridges are spaced apart from each other, which is such as to allow the foot to sink into the space contained between two successive ridges.

This not only improves the adhesion of the foot to the hosiery, but also reduces the relative movement of the foot relative to the hosiery within the boot.

However, as a result, ventilation inside the boot is difficult, since the spaces between the ridges do not form channels that would facilitate the removal of warm air and sweat in the vapor phase.

US 9226527 B2 discloses ideas for a hosiery in which the surface in contact with the wearer's foot comprises a plurality of ridges which are at least partially arranged to form an angle or curve with respect to a straight line extending in the transverse direction. regarding the foot.

These ridges run upward from the ball of the foot to the ball of the foot.

Such prior art solutions have the disadvantage that the vapor phase sweat is not channeled along the shortest route from the foot to the ball of the foot, thereby increasing the risk of condensation.

Finally, document WO2011/143369 discloses ideas for creating a hosiery comprising:

- protective elements adapted to absorb shocks in the toe and heel area;

- shock-absorbing segments in the central part of the foot, located between the forefoot and the back of the foot, oriented in the direction of walking so that channels are formed adapted to the direction of sweat away from the foot of the foot.

However, this well-known solution also has a number of disadvantages.

The channels are located symmetrically with respect to the longitudinal axis of the foot, i.e. have no difference between the inside of the foot and the outside of the foot, so that the same sock can be worn without distinction on the right foot or the left foot, and furthermore, the shock-absorbing segments are arranged in a closed way, to which closed channels are demarcated.

For these reasons, the channels are not adapted to the removal of sweat from the foot of the foot.

Also, these channels do not direct sweat away from the foot along the shortest route, and thus do not contribute to reducing the risk of condensation through them.

The aim of the present invention is to provide a hosiery suitable for improving the known state of affairs in this field with respect to one or more of the aspects mentioned above.

Within the scope of this objective, it is an object of the invention to provide a hosiery capable of providing better transfer of sweat in both the vapor phase and the liquid phase, compared to conventional hosiery.

Another object of the invention is to provide a hosiery capable of providing a sufficient level of ventilation around the wearer's foot for adequate exchange of heat and water vapor between the internal microclimate of the boot and the external environment, even if the outer material of the boot is not breathable ("breathable").

It is another object of the invention to provide a hosiery which, by providing a natural regulation of the wearer's foot temperature, makes it possible to keep it dry for a longer period of time compared to conventional hosiery, resulting in greater comfort. .

It is another object of the invention to provide a hosiery capable of providing an adequate level of support for various areas of the wearer's foot.

Another object of the present invention is to overcome the shortcomings of the known state of the art in an alternative way to any of the existing solutions.

Another object of the invention is to provide a highly reliable, easy to manufacture hosiery at a low cost.

This goal and these and other objects that will become more apparent in the following are achieved and solved by providing a hosiery of the type containing a plurality of channels alternating with ridges, characterized in that said channels have, at least in part, a different width.

Additional features and advantages of the invention will become more apparent upon reading the following detailed description of a preferred, but not exclusive, embodiment of a hosiery according to the invention, which is illustrated by way of non-limiting example, in conjunction with the drawings, which show:

figure 1 is a view of the foot of the hosiery, according to the invention;

figure 2 is a view of the first side of the hosiery, according to the invention;

figure 3 is a perspective view of a hosiery according to the invention;

figure 4 is a view from the second side of the hosiery, according to the invention;

figure 5 is a top view of a hosiery according to the invention;

Fig. 6 is another perspective view of a hosiery according to the invention;

Fig. 7 is another perspective view of a hosiery according to the invention.

The hosiery according to the invention is generally designated with the number 10.

The hosiery 10 contains preferred passages for air and sweat in the vapor phase.

The term "preferred" as used herein means "tends to be preferred" to vapor phase sweat which, when it encounters a material containing a ported and non-ported portion, is attracted to and tends to "prefer" the passages.

As a result, sweat in the vapor phase tends to prefer the ported portion 20 over the non-perforated portion.

Such preferred passages are defined by the channels 11 for the passage of sweat in the vapor phase.

Such channels 11 are defined by the presence of ridges 12 with which they alternate.

The hosiery 10 comprises: a first zone 13 substantially corresponding to the surface of the foot, and is divided into five parts:

- the first section C, which essentially corresponds to the surface of the calcaneus;

- a second section L, which essentially corresponds to the lateral surface of the foot;

- the third section M, which essentially corresponds to the medial surface of the foot;

- the fourth area T, which essentially corresponds to the surface of the heads of the metatarsal bone;

- the fifth section D, which essentially corresponds to the distant surface.

The second section L of the first zone 13 requires significant support.

For this reason, such a second portion L comprises ridges 12 which follow the protrusion of the lateral longitudinal arch at the flat extent of the foot, as shown in FIG. l.

Thus, the foot rests on a surface that follows the shape of the foot itself.

In contrast, the third section M of the first zone 13 requires less support than the second section L of the first zone 13.

The third section M of the first zone 13 is thus provided with ridges 12 located at a greater distance between them, in comparison with the distance between the ridges 12 of the second section L of the first zone 13.

Thus, in the third section M of the first zone 13, there are wider channels 11, which allow for a greater level of ventilation than in the second section L of the first zone 13, in which, on the contrary, adequate support for the foot is the predominant need.

The channels 11 alternating with the ridges 12 in the third section M of the first zone 13 have an extent preferably parallel to the transverse direction of the foot, located essentially perpendicular to the longitudinal direction of the foot.

The expression "longitudinal direction of the foot" in the present description means the direction of the axis connecting the forefoot to the back of the foot, known as the "Brannock Axis", i. an axis that bisects the foot in the forefoot towards the hindfoot.

Thus, sweat in the vapor phase follows the shortest route leading to the sides of the foot, and from there it rises to the ankle by means of a traction effect, and then it exits to the external environment.

The expression "draft effect" means a physical phenomenon by which warm air moves from bottom to top.

The fourth section T of the first zone 13 is also involved in the support of the foot, and this requires support similar to that required for the second section L of the first zone 13.

In the fourth section T and the second section L of the first zone 13, the ridges 12 and the channels 11 are arranged substantially in the same way.

In the fourth section T and in the second section L of the first zone 13, the channels 11, alternating with the ridges 12, have an extent that is essentially parallel to the transverse direction of the foot.

Taking into account that:

- body weight, in a static state and during movement, rests mainly on the calcaneus, which is the most massive bone of the tarsus;

- the surface of the foot near the calcaneus almost does not contain sweat glands;

in the first section C of the first zone 13, the need for foot support is more important than the need for an adequate level of ventilation. For these reasons, the hosiery 10 is substantially free of ridges and channels in the first section C of the first zone 13.

In general, the foot can be schematically represented as a static posterior triangle and a dynamic anterior triangle.

This dynamic anterior triangle runs along the portion of the foot that is most exposed to the propulsion phase, during which effective footing is essential to ensure equally efficient forward propulsion.

Thus, in the anterior triangle, the need for foot support is predominant.

The front triangle is located essentially near the fifth section D of the first zone 13, which, as shown in Fig.l, does not contain essentially ridges and channels, like the first section C of the first zone 13.

Where the need for support is more important, the textile material of which the hosiery 10 is made has a stronger structure, i. it contains a textile material of greater density.

Such a textile material of greater density can be obtained, for example, by arranging the ridges 12, which define the channels 11, with a smaller distance between them.

Thus, in order to obtain a textile material with a stronger structure and greater density, and increased load-bearing capacity, the ridges 12, which define the channels 11, are placed with a smaller distance between them, relative to the distance between the ridges 12 in areas where the need for ventilation is more important, than the need for support.

In the first and fifth sections C and D of the first zone 13, which are substantially free of channels, the textile material is advantageously made stronger by using thicker threads and/or a tighter weave of threads.

The second and fourth portions L and T of the first zone 13 are portions of high textile density.

The expression "high density textile material" means that the distance between the ridges 12 is less than the distance between the ridges 12 in the areas of the textile material with low density.

In these two sections, the second L and the fourth T, of the first zone 13, the ridges 12 have a width preferably between 1 mm and 7 mm;

the channels 11 have a width preferably between 1 mm and 3 mm.

The third section M of the first zone 13 is a low density textile section.

The term "low density textile" means that the distance between the ridges 12 is greater than the distance between the ridges 12 in areas of the high density textile. This results in a textile material with a lower density.

In this third section M of the first zone 13:

the ridges 12 have a width preferably between 2 mm and 5 mm;

the channels 11 have a width preferably between 3 mm and 6 mm.

The hosiery 10 also includes a second zone 14, shown in FIG. 2, which covers the outer instep of the foot.

The second zone 14, in turn, contains:

- the first section E, outer;

- the second section F, lateral malleolus, located essentially near the lateral region of the ankle;

a third section G, rear, constituting essentially a ledge perpendicular to the plane K on which the foot rests, of the first section C, of the first zone 13, on the second zone 14;

- a fourth section H, anterior, constituting essentially a ledge perpendicular to the plane K on which the foot rests, of the fifth section D of the first zone 13, on the second zone 14;

- the fifth section I, intermediate between the fourth section H and the first section E.

The first and second sections E and F of the second zone 14 contain channels 11, alternating with ridges 12, passing upwards, in the conditions of use of the product 10, at an inclination Θ, ranging from 50º up to 80º, preferably from 60º up to 70º, measured relative to the K plane on which the foot rests.

From experimental tests, such a slope Θ has been shown to be effective in directing sweat in the vapor phase towards the top of the hosiery 10 in the configuration for use.

In fact, conventional hosiery includes channels extending from the foot to the ankle, thus predominantly at an angle of inclination greater than 90º.

Thus, however, these channels concentrate all the sweat in the vapor phase in a limited area near the ankle.

This determines the overload of sweat in the vapor phase in this area, near the ankle, in which it accumulates, thus increasing the risk of condensation.

In addition, for passage of channels from the sole of the foot to the ankle, it is necessary to narrow these channels and/or converge the plurality of channels into one channel system to accommodate ankle dimensions that are smaller than the foot.

This results in complex hosiery manufacturing and the suggestion that the zones must be provided with textiles of very different textures in the second zone, which creates discomfort for the wearer.

In order to simplify the implementation of some conventional products, the presence of channels was limited to a certain percentage, while others were excluded, due to which, however, the overall effectiveness of the product was reduced.

The hosiery 10, on the contrary, was suitable not only for distributing sweat in the vapor phase near the instep of the foot, but also for directing it towards the collector 15 shown in FIG. 3.

In fact, the hosiery 10 is provided with channels 11 in the first section E of the second zone 14, which converge into a collector 15, directing sweat in the vapor phase thereto.

Manifold 15 extends upward, in configuration for use, i.e. to the instep of the foot, and defines the boundary:

- with its first section, between the first section E and the fifth section I of the second zone 14;

- with its second section, between the first section E of the second zone 14 and the part 17 described below.

In order to increase the channels 11 into which the sweat in the vapor phase is distributed, the ridges 12 contained in the part 17 and located closest to the collector 15 may contain breaks, for example, indicated by reference numbers 19a, 19b, 19c and 19d.

Breaks 19a-19d promote communication between adjacent channels 11 and thus promote diffusion of sweat in the vapor phase.

The second section F of the second zone 14 facilitates the transit of sweat in the vapor phase to the ankle, and in particular the sweat secreted by the sweat glands located below the ankle.

In fact, near the ankle, the hosiery 10 adheres better to the wearer's foot due to the protrusion of the ankle itself, and this creates a reduction in the space between the hosiery and the foot, preventing the rise of sweat in the vapor phase. Thus, in this part, sweat in the vapor phase requires passages that would facilitate its rise to the ankle.

The first and second sections E and F of the second zone 14 are zones of low density textile material and containing:

- ridges 12 having a width preferably between 2 mm and 5 mm;

channels 11 having a width of 3 mm to 6 mm.

The hosiery 10 also includes a third zone 16 shown in FIG. 4.

The third zone 16 wraps around the inside ball of the foot and this zone contains:

- the first section E', internal;

- the second section F', medial malleolus, located essentially near the medial part of the ankle;

- a third section G', rear, constituting essentially a ledge perpendicular to the plane K on which the foot rests, of the first section C of the first zone 13, on the third zone 16;

a fourth section H', anterior, which constitutes essentially a protrusion perpendicular to the plane K on which the foot rests, of the fifth section D of the first zone 13, on the third zone 16;

- the fifth section I', intermediate between the fourth section H and the first section E'.

Such sections, from the first E' to the fifth I', of the third zone 16, are similar to the corresponding sections, from the first E to the fifth I, of the second zone 14, described earlier.

As in the second zone 14, also in the third zone 16, there is a collector 15' similar to the collector 15.

The channels 11 of the first section E' of the third zone 16 converge into the collector 15', directing sweat in the vapor phase towards it.

The hosiery 10 also includes the part 17 shown in the drawings.

This part 17 extends from the back of the foot, in the longitudinal direction from the fifth sections H and H', respectively, of the second zone 14 and the third zone 16, up to the upper edge 18.

The first sections E and E', the second sections F and F', respectively, of the second zone 14 and the third zone 16, and part 17 are demarcated in the upper section, by means of such an edge 18.

This upper edge 18 is essentially a curved profile, which, in the embodiment shown in the drawings, is located below the circumference of the ankle.

The expression "ankle circumference" in the present description means the minimum circumference parallel to the plane on which the foot rests, immediately above the ankle.

This part 17 is demarcated laterally:

- for the first section, through manifolds 15 and 15';

- for the second section, through the fourth sections H and H' and through the fifth sections I and I', respectively, of the second zone 14 and the third zone 16.

The fifth sections I and I', respectively, of the second zone 14 and the third zone 16, are delimited by part 17, by the respective manifold 15 or 15', by the respective fourth section H or H' and, below, by the fourth section T of the first zone 13.

Part 17 extends over a width w of 15% to 30%, preferably 20% to 25%, of the instep of the foot.

The size of the instep is the smallest circumference behind the projection of the median cuneiform bone of the foot.

Part 17 of article 10 runs along a length of 40% to 60% of the length of the foot.

The expression "length of the foot" in the present description means the distance measured along the Brannock axis, indicated by position b in figure 5, from the back of the heel to the toe of the longest toe.

As shown in figures 5 and 6, the manifolds 15 and 15' extend from the top edge 18:

- for the first section n', equal to approximately half the length a of part 17, mainly in the direction of the Brannock axis b;

- for the second section n", equal to approximately 0.15-0.35 of the length a of the part 17 following the oblique direction up to the corresponding lateral edge 20, 20' of the fourth section T of the first zone 13. The collectors 15, 15' have a width of 1 mm to 6 mm.

The breaks 19a-19d are advantageously located preferably along the first section n'.

The gaps 19a-19d are preferably 1 mm to 5 mm wide, more preferably 2 mm to 4 mm wide.

The dimensions of the fifth sections I and I' of the second zone 14 and the third zone 16 are determined by the dimensions of the portion 17 and the geometry of the manifolds 15 and 15'.

The part 17 and the fifth sections I and I' of the second zone 14 and the third zone 16 comprise channels 11 alternating with ridges 12 which extend predominantly in the direction of the Brannock axis b.

In part 17, the channels 11 and ridges 12 extend from the fifth sections H and H' of the second zone 14 and the third zone 16 up to the upper edge 18.

Thus, the movement of sweat in the vapor phase to the ankle is supported, from which it then exits to the outside.

In the fifth sections I and I' of the second zone 14 and the third zone 16, the channels 11 and ridges 12 extend, respectively, from the fourth sections H and H' of the second zone 14 and the third zone 16, up to the collectors 15 and 15'.

In practice, the channels 11 of the fifth sections I and I' converge into manifolds 15 and 15'.

This makes it possible to direct the sweat in the vapor phase, which is transported through the channels 11, to the collectors 15 and 15'.

Sweat in the vapor phase, rising due to the draft effect, is transported by the collectors 15 and 15' to the edge 18.

This makes it possible to maintain the structure of the textile material constituting the hosiery 10 in a substantially uniform state, reducing and/or eliminating restrictions created by ridges and/or channel systems that could cause discomfort to the wearer.

A hosiery is, in fact, a piece of clothing adapted to direct contact with the wearer's skin in such a way that the structure of the textile material from which the product is made is directly felt by the wearer.

Part 17 and the fifth sections I and I' of the second zone 14 and the third zone 16 are low density textile zones:

the ridges 12 have a width preferably between 2 mm and 5 mm;

- the channels have a width of 3 mm to 6 mm.

Figure 7 shows a rear perspective view of the product 10.

In this embodiment, the hosiery 10 is a sock that extends up to the ankle, however, the invention is not limited to this type, but can be applied in an equivalent way, for example, in the formation of stockings that reach up to the knees, where the top edge 18 is located above ankle circumference.

The hosiery 10 is preferably made from a textile material containing natural and/or synthetic threads.

Advantageously, hydrophobic threads can be used on surfaces in contact with the wearer's body, and hydrophilic threads can be used on surfaces facing outward to the environment in such a way as to also improve the removal of fluid phase sweat from the wearer's body.

The textile material may conveniently contain areas of more porous structure obtained, for example, by knitting, where the threads are located with a large distance between them, so as to facilitate the passage of sweat in the vapor phase through the textile material.

In particular, the textile material can be made from, for example, cotton, wool, polyester, polyamide, and the like, or combinations thereof.

The textile material can be formed from one or more layers: for example, from a first layer, favorably hydrophobic, in the region of the channels 11, to which is added a second layer, favorably hydrophilic, in the region of the ridges 12.

This configuration is advantageous because the liquid phase sweat is not captured by the first layer, which is the layer that comes into contact with the wearer's foot, but instead the sweat moves away from the foot as it is absorbed by the second layer.

The thickness of the textile material in the region of the ridges 12 is 0.3 mm - 3.0 mm greater than the thickness in the region of the channels 11.

The ridges 12 thus have a thickness between 0.3 mm and 3.0 mm.

In the drawings, the arrows labeled V show the route of sweat in the vapor phase within the channels 11.

In practice, it has been found that the invention fully achieves the intended purpose and objectives by providing a hosiery capable of providing an adequate level of support for various areas of the wearer's foot.

Through the use of the invention, a developed hosiery is obtained which, by allowing the temperature of the user's foot to naturally regulate, allows it to be kept dry for a longer period of time compared to conventional hosiery, resulting in greater comfort.

It should be noted that the invention provides a hosiery that provides a sufficient level of ventilation around the wearer's foot for adequate heat and water vapor exchange between the boot's internal microclimate and the outside environment, even if the boot's outer material is not breathable.

Finally, the invention provides a hosiery capable of providing better transfer of sweat in both the vapor phase and the liquid phase compared to conventional hosiery.

The invention thus set forth is susceptible to a number of modifications and variations, all of which fall within the scope of the appended claims. In addition, all parts can be replaced by other, technically equivalent elements.

In practice, the materials used are compatible with the specific use, sizes and shapes of the contingent, can be any according to the requirements and state of the art in this field.
