Description

[0001] SPORTS TEXTILE ITEM WITH ADJUSTABLE COMPRESSION AT THE LEVEL OF

[0002] CALVES

[0003] 1. Technical field of the invention

[0004] The present invention relates to the field of textile articles, in particular to sports textile articles intended to cover all or part of a user's calf. It relates specifically, but is not limited to, sports socks, compression sleeves, technical stockings, independent textile bands, or any stretchable or modified textile designed to be worn during physical activities that heavily stress the calf muscles.

[0005] The invention falls within the field of functional textiles that allow for adjusting the pressure exerted on the calf, and relates more broadly to equipment designed to improve the comfort, support and mechanical management of this anatomical area during sporting activity.

[0006] It finds particular application in sports involving accelerations, changes of support, repeated contractions or intense muscular demands on the calf, such as football, rugby, basketball, handball, running, athletics, cycling or indoor sports.

[0007] 2. Claim of priority

[0008] This international application claims priority from French application FR2413377, filed on December 3, 2024. The content of that earlier application is incorporated herein by reference, in accordance with Rule 26bis.1 of the Patent Cooperation Treaty (PCT), for the disclosure elements actually contained in the said French application. Certain claims, technical features, and embodiments described in this international application constitute additional developments or variations that are not included in French application FR2413377 and therefore do not benefit from the aforementioned priority date. This international application thus constitutes an expansion of the initial disclosure, including both features benefiting from French priority and new features introduced in the international filing.

[0009] 3. Prior art

[0010] Modern sportswear, such as compression socks, sleeves, or stockings, typically applies uniform compression directly to the calf. This compression results from the structural elasticity of the fabric and cannot be adjusted.

[0011] This uniform compression has several technical limitations.

[0012] - it is not locally adjustable and cannot be reduced or increased on a specific portion of the calf;

[0013] - it does not take into account the varied morphologies of calves (thin, thick, asymmetrical, very muscular, short or long);

[0014] - it does not adapt to the volumetric variations of the calf;

[0015] - it can cause muscle discomfort, skin markings, pain, excessive tension or discomfort;

[0016] - it does not allow any dynamic modulation during phases of effort, explosiveness, recovery or the onset of muscle fatigue (swelling, congestion).

[0017] In sports, particularly football, many players make small cuts in their socks around the calf to relieve compression. These cuts:

[0018] - deteriorate the integrity of the textile;

[0019] - cause a risk of tearing;

[0020] - cause slippage; - do not allow any controlled modulation of compression;

[0021] To the applicant's knowledge, no prior art document discloses a textile article that allows for controlled and targeted pressure release at the calf level, adaptation to different morphologies, controlled dynamic modulation possibly multi-zone during activity, as well as a durable, reproducible and industrializable solution.

[0022] 4. Technical problem

[0023] The invention aims to overcome the aforementioned limitations by providing a solution that simultaneously addresses:

[0024] - the excessive, uniform and non-adjustable compression exerted on the calf by classic sports textiles;

[0025] - the lack of adaptation to variations in shape, size and volume of the calf which occur in the same user depending on the phases of effort, this muscle area being subject to rapid fluctuations in volume and congestion;

[0026] - the failure to take into account morphological differences between users, as calves exhibit great inter-individual diversity (diameter, taper, muscle profile, asymmetries), whereas existing standardized sizes do not cover this structural variability;

[0027] - the impossibility of making a dynamic and localized adjustment of the compression specifically at the level of the calf, allowing either to lighten the textile constraint, or to increase the compression on a delimited area if desired;

[0028] - the absence of a solution combining comfort, mechanical stability, reliable textile support, protection of sensitive muscle areas and adaptation to variations in tension at the calf level, all without alteration of the textile as in artisanal cuts.

[0029] 5. Summary of the Invention The invention relates to a sports textile article intended to cover the calf totally or partially and configured to allow controlled, localized, progressive, and reversible modulation of the compression exerted on the calf. The article comprises a main textile structure, generally stretchable, associated with at least one local decompression element, including an opening and / or a slightly compressive or non-compressive textile zone, as well as at least one mechanical modulation element, including a fold-down section and / or a mechanical tightening means.

[0030] Local decompression elements reduce or even eliminate the pressure exerted by conventional compression garments, while mechanical modulation elements allow for the voluntary, progressive, and reversible reintroduction, adjustment, or increase of compression. These distinct yet working components offer personalized modulation of pressure applied to the calf, adaptable to morphological variations, muscular stresses, and different phases of athletic activity.

[0031] Depending on the design, the mechanical modulation element can be combined with either an opening or a non-compressive zone, allowing for precise, multi-level, and dynamic compression regulation. The garment can be made in the form of a sock, sleeve, or independent textile band, and can incorporate various options to improve stability, comfort, and morphological adaptability.

[0032] Designed in this way, the invention makes it possible to obtain personalized, scalable and controlled compression, which is difficult to achieve with the uniform pressure compression articles of the state of the art.

[0051] 7. Detailed description of the invention

[0052] The invention relates to a sports textile article intended to cover totally or partially the calf of a user, comprising:

[0053] 1. a main textile structure, generally stretchable, serving as mechanical support and forming the basic envelope of the article;

[0054] 2. at least one local decompression element, consisting either of an opening in the textile structure, or of a weakly compressive or non-compressive textile area;

[0055] 3. at least one mechanical modulation element, including a folding part and / or a mechanical tightening means intended to increase, reduce or adjust compression locally at the calf level.

[0056] These elements are distinct from each other, but configured to cooperate in order to allow controlled, localized, progressive and reversible modulation of the compression exerted at the calf level.

[0057] This cooperation allows the user to adapt in real time the pressure applied to the calf according to their morphology, their functional needs and the successive phases of activity (warm-up, intense effort, recovery), as well as to the variations in muscle volume during the activity.

[0058] The opening and / or the non-compressive zone ensures local structural decompression, even eliminating or reducing the continuous stress exerted by the classic textile on the muscle, while the foldable part and / or the tightening means allow the compression to be reintroduced, modulated or increased in a controlled and reversible manner.

[0059] The embodiments described in the following sections illustrate different ways of arranging, combining or optimizing these elements to achieve reliable, personalized and multi-zone modulation of compression, while preserving textile stability and the structural integrity of the article.

[0060] 7.1. First architecture: adjustable opening and flap

[0061] According to a first embodiment, the garment includes at least one opening located at the calf and delimited by a border, possibly reinforced. The border of the opening may be formed by a rolled hem, heat sealing, ultrasonic welding, an anti-fray band, anti-marking foam, or any other equivalent finish that limits the risk of fraying, tearing, or skin marking. The opening constitutes a localized area in which the structural compression of the textile is eliminated or significantly reduced, allowing for immediate mechanical unloading of the muscle and increased local flexibility of the textile. This opening also enhances the textile's ability to adapt better to different body shapes and to accommodate variations in muscle volume during periods of exertion or recovery.

[0062] The opening is designed to cooperate with the flap in order to be covered, stabilized and mechanically controlled.

[0063] Each opening is associated with a hinged section (or "flap") configured to allow for localized and reversible compression adjustment. The hinged section is a structural or functional element, preferably flexible, which can be:

[0064] - attached to the main textile via stitching, gluing, ultrasonic welding, or any equivalent functional anchoring,

[0065] - partially attached to the textile by having only one point of attachment, - or entirely removable, which can be fixed, removed or replaced according to the user's needs.

[0066] The folding section comprises a base (or anchoring area) and a free portion configured to fully or partially cover the opening. This free portion is sized to be movable and fixed to a textile area opposite the opening in various positions, each position determining a level of closure of the opening and, consequently, a level of tension exerted on the calf area.

[0067] The folding section can be made:

[0068] - made of textile material,

[0069] - made of polymer material,

[0070] - made of composite material,

[0071] - or in any textile / non-textile combination, and may adopt any shape suitable for effectively covering the opening and improving stability, support and compression control, including:

[0072] - rectangular,

[0073] - oval,

[0074] - lying down,

[0075] - asymmetrical,

[0076] - or any geometry optimized to fit the curves of the calf and ensure uniform coverage.

[0077] It can have a thickness, rigidity or elasticity chosen according to the level of support or comfort desired.

[0078] The folding part also includes one or more adjustable fastening means, selected from self-gripping strips, laces, elastic cords, straps, mechanical clips, buckles, magnetic elements, snap fasteners, reusable adhesives or any functional equivalent.

[0079] These fastening methods ensure:

[0080] - stable retention of the flap in the chosen position

[0081] - a clean and aesthetically pleasing cover for the opening,

[0082] - mechanical stability preventing the flap from shifting under stress,

[0083] - a good distribution of the applied voltage,

[0084] - a reproducible and precise adjustment chosen by the user.

[0085] The flap works mechanically with the opening to locally adjust the tension of the fabric. Its operation is based on a principle of controlled overlap of the flap over a fixing area:

[0086] - the closer the free portion of the flap is to the edges of the opening, the lower the tension applied to the textile, generating reduced compression;

[0087] - the more the flap is pulled and fixed in a position further from the edges of the opening on the fixing area provided for this purpose, the more the textile structure is stretched, which locally increases the compression.

[0088] The traction is applied in such a way as to bring the free portion of the flap closer to the fixing area provided for this purpose, regardless of the exact orientation resulting from the configuration of the textile, allowing a controlled, stable adjustment compatible with the mechanics of the textile at the calf level.

[0089] This adjustment mechanism allows for fine, progressive and reversible modulation of the compression exerted on the exposed muscle area.

[0090] In some variations, the fold-down section can also be configured to pass through one or more slots or openings in the fabric, allowing for tightening from both inside and / or outside the garment. The slots can be reinforced as needed. This mechanism provides an additional option for directional or bidirectional compression.

[0091] The combination of the opening and the adjustable flap provides several significant technical effects:

[0092] - an instant and controlled release of textile tension at the calf level,

[0093] - a reduction in excessive structural compression,

[0094] - Increased morphological adaptation to different calf shapes (thin, thick, asymmetrical, very muscular),

[0095] - dynamic modulation during activity, allowing the athlete to immediately modify the compression according to their perception.

[0096] - improved textile stabilization, limiting slippage or rotation,

[0097] - Ergonomics are maintained thanks to the flap's cover, even when the opening is initially wide.

[0098] - superior structural support compared to hand-cut socks, which degrade the textile without offering controlled adjustment capabilities.

[0099] This architecture provides a robust solution for achieving personalized, scalable, localized and controlled compression, impossible to achieve with state-of-the-art uniform compression sports textiles.

[0100] 7.2. Second architecture: non-compressive zone and mechanical tightening means

[0101] In a second configuration, the garment includes a low-compression or non-compression textile zone, achieved through excess material, reduced elasticity, differentiated weaving or knitting, decreased mesh density, partial absence of elastic thread, an added panel, or any equivalent textile means of locally reducing pressure on the calf. The non-compression zone may also consist of an openwork pattern incorporating perforations, micro-openings, alveoli, laser cuts, or a breathable mesh, in order to achieve localized reduced compression while ensuring improved ventilation.

[0102] This area provides a space where the stress exerted by the textile is naturally low, allowing the muscle to expand and adapt to changes in volume during exertion, congestion or recovery, while remaining integrated into the overall structure of the article.

[0103] This non-compressive zone is associated with a mechanical tightening device, which can be voluntarily actuated by the user. The mechanical device is configured to increase or decrease the compression applied around this zone in a localized, progressive, and reversible manner.

[0104] Definition of the mechanical tightening method

[0105] The mechanical tightening means comprises an element that can be grasped, pulled, and fixed by the user, selected from:

[0106] - shoelaces,

[0107] - cords or elastic cords,

[0108] - adjustable textile straps or ribbons,

[0109] - self-adhesive strips,

[0110] - clamping brackets or tabs,

[0111] - systems combining strap and buckle,

[0112] - similar elements providing a mechanical clamping function.

[0113] These elements can be attached to the main textile (by sewing, gluing, welding, or localized anchoring) or partially attached, with a free portion designed to be pulled and fixed onto a textile surface intended for this purpose (fixing area, hook and loop fastener, self-gripping receiving section, etc.). The mechanical tightening mechanism is designed to be operated at will by the user, allowing them to:

[0114] - bring the material closer together and tighten it around the non-compressive area,

[0115] - or conversely, release the tension to reduce compression.

[0116] Mechanical operating principle

[0117] The operation relies on controlled mechanical tightening, generally in a direction adapted to the geometry of the area to be tightened, for example roughly circumferential at the calf, without this orientation being limiting:

[0118] - when the clamping means is not very tight and fixed in the immediate vicinity of the non-compressive zone, the pressure around this zone remains low;

[0119] - when the tightening means is pulled further and fixed in a more taut position, the surrounding textile material is brought back and compressed around the non-compressive area, locally increasing the compression.

[0120] The applied voltage depends directly on:

[0121] - the pulling force exerted by the user,

[0122] - the distance between the anchor point and the non-compressive zone,

[0123] - the chosen fastening method (position of the strap, lace, hook and loop fastener, etc.).

[0124] The adjustment is gradual, reversible and repeatable, without removing the item.

[0125] This architecture allows for:

[0126] - a significant reduction in initial pressure on a sensitive or voluminous muscle area of ​​the calf thanks to the non-compressive zone;

[0127] - progressive and controlled compression, adjustable by the user via the mechanical tightening mechanism; - continuous adaptation to variations in muscle volume (congestion, fatigue, warm-up, end of match);

[0128] - a dynamic adjustment during activity, allowing you to increase or decrease compression without removing the sock or sleeve;

[0129] - the possibility of maintaining a delimited decompressed area, while preserving the overall stability of the textile thanks to peripheral tightening;

[0130] - Advanced customization of compression, based on the user's morphology, sensations and local sensitivities.

[0131] The cooperation between the non-compressive zone and the mechanical tightening means makes it possible to define, at the level of the calf, zones of reduced, moderate or reinforced pressure, with direct control by the user, while preserving the integrity and overall support of the textile article.

[0132] The non-compressive zone may also be covered by a hinged section, primarily for aesthetic purposes, configured to visually conceal the non-compressive zone and, where applicable, the associated mechanical tightening mechanism(s), without, however, exerting significant compression. This section, lacking a tightening function, may bear markings, logos, numbers, decorative elements, or various customizations, without altering either the load-discharging function of the underlying zone or the modulation capacity provided by the mechanical tightening mechanism.

[0133] 7.3. Common Options and Variants

[0134] Various options can be implemented in a manner common to both architectures described above.

[0135] The article may include one or more modular zones, whether in the form of:

[0136] - openings, - areas of reduced pressure,

[0137] - of non-compressive zones,

[0138] - of openwork or perforated areas, positioned to allow independent adjustment on the upper, middle and / or lower part of the calf, according to a distribution adapted to the morphology of the calf and the type of mechanical regulation envisaged, these upper, middle and lower areas being cited as non-limiting examples of possible positions at the level of the calf.

[0139] The item can be designed to fit various body shapes, including short, long, thin, thick, asymmetrical or very muscular calves, by means of several combinable adjustment levels and by providing different predefined sizes, for example XS, S, M, L, XL, XXL or any equivalent or customized gradation.

[0140] The openings, non-compressive zones and foldable parts can adopt various shapes, including circular, oval, elongated, elliptical, polygonal, rectangular or any other shape adapted to the morphology of a calf, in order to optimize the compromise between release of constraint, support, ergonomics and aesthetics.

[0141] In some variations, the textile structure may exhibit a decreasing compression gradient around the opening and / or around the low-compression or non-compression zone. This gradient can be achieved by locally modifying the knitting, weave, yarn, stitch orientation, or textile thickness to progressively reduce the pressure exerted as one approaches this zone. This gradient helps absorb the pressure transition between the open or non-compression zone and the adjacent compression zone, and helps limit sudden stress points, local shear stress, and skin irritation.

[0142] The article may also include one or more anti-slip or anti-slip inserts, arranged on the inner or outer face of the textile structure, on the foldable part and / or on the tightening means, these inserts being made of silicone, rubber, polyurethane, micro-pimples or equivalent textured structures, so as to limit slippage and stabilize the position of the article on the leg.

[0143] In some variants, the article may further include at least one visual and / or tactile indicator, for example in the form of graduated marks, markings, textured areas or pattern changes, located near an opening, a non-compressive area, a tightening means or a hinged part, so as to enable the user to appreciate or reproduce a given level of tightening and / or compression.

[0144] A soft panel, lining, veil or insert providing a soft interface with the skin may be placed at least opposite the opening, the non-compressive area and / or the main support area at the calf, in order to reduce the risk of skin shearing without exerting significant pressure.

[0145] The article may finally include a ventilation or thermoregulation zone, such as an airy mesh, perforation or breathable textile, positioned opposite or near the opening or non-compressive zone, and possibly covered by the fold-down part, so as to improve thermal comfort without compromising the compression modulation function.

[0146] The main textile structure and, where applicable, the foldable parts, the non-compressive areas, the tightening means and the added elements may be made from stretchable textile materials including in particular synthetic and / or natural fibers, technical and / or composite yarns, in the form of knitted, woven or non-woven textiles, and / or shape memory textiles or equivalent materials ensuring elasticity and comfort suitable for sports use.

[0147] In some variations, the garment includes at least one adjustment element (e.g., tab, band, strap, or cord, or any equivalent element) sized to pass through one or more slots or openings in the textile structure or in a fold-over section, said slots possibly being reinforced. The adjustment element is configured to be pulled to apply local tightening from the inside and / or outside of the garment, and then secured to itself or to a corresponding area by means of hook-and-loop fasteners, elastic ties, buckles, or any equivalent means of attachment. This mechanism allows for precise tension application, bidirectional modulation (internal / external), and adaptation to various body shapes. This constitutes an alternative or complement to the fold-over described above.

[0148] The product can be made as a full sock, a calf-covering sleeve, or a separate textile band designed to partially encircle the calf; these different configurations can be combined into a modular system. Such a system can optionally be used with an external accessory, such as a shin guard or other protective element that covers the calf area.

[0149] The item is further designed to reduce mechanical stress and excessive compression effects on the calf, and to adapt to different calf shapes and sizes, in order to improve functional comfort when practicing sports that heavily stress this area, including football, rugby, basketball, handball, running, athletics, cycling, indoor sports or any physical activity requiring the wearing of textiles covering the calf.

[0150] 7.4. Technical effects common to all variants

[0151] The various architectures and variants described above allow, alone or in combination, for obtaining, in particular:

[0152] - targeted and controlled release of textile constraint, eliminating or reducing unwanted compression on an active muscle area, thanks to openings and non-compressive zones;

[0153] - the possibility of locally increasing compression, when desired by the user (reinforced support, controlled tightening sensation, phases of intense effort), by means of adjustable flaps or mechanical tightening devices; - an extensive morphological adaptation, covering the entire anatomical spectrum of calves (thin, thick, stocky, asymmetrical, long, short, very muscular), thanks to the modular zones and the various mechanical means of tension adjustment;

[0154] - a dynamic adjustment during activity, allowing the athlete to instantly adjust the compression according to their feelings, muscle congestion, the effort or recovery phase, without removing the textile item;

[0155] - an improvement in functional comfort and tolerance to effort, thanks to the reduction of areas of excessive compression and the possibility of maintaining decompressed areas while stabilizing the textile;

[0156] - increased stability of the textile structure, limiting slippage, rolling, rotation or any uncontrolled movement at the calf level, thanks to the combined action of flaps, tightening devices and anti-slip inserts;

[0157] - fine, graduated and multi-zone customization of compression levels, impossible to achieve with classic sports socks with uniform compression.

[0158] Designed in this way, the invention makes it possible to obtain personalized, evolving, localized, multi-zone, dynamic and controlled compression, technically inaccessible with current sports textiles with uniform compression.
