Description

Title of the invention: System for holding a sock in place

[0001] The present invention belongs to the field of clothing articles, and more particularly to the field of knitted accessories of the stockings and socks type.

[0002] It relates to a sock intended to be worn in low-top shoes, comprising a flexible element fixed at the back so as to protrude from the shoe, which can be folded down and fixed to the latter to keep the sock in place during use. The invention also relates to a footwear assembly comprising such a sock and a low-top shoe provided with connecting elements between them, as well as an assembly kit.

[0003] Socks are knitted hosiery items, belonging to the category of stockings, intended to cover the foot and a more or less extended part of the leg of a user. There are different types whose names are more or less established by practice: in general, the knee-high sock covers the lower half of the leg, the long sock goes to the knee, and the maxi-sock goes even higher. The ankle sock is a variant that stops just above the ankle, while the short sock, called "mini-sock" or "invisible sock", only covers the foot without covering the ankle, so that it can be completely hidden by a closed shoe such as tennis shoes, sneakers, moccasins, or other.

[0004] Socks in their most general definition are formed from a tubular knit (fabric formed from meshes), comprising a footwear part intended to surround the foot and to be inside a shoe, and a rising part (except for invisible socks) intended to wrap around the leg. The knit is closed at its distal end, that is to say at the end of the footwear part corresponding to the tip of the foot, but retains an open edge at its proximal end, through which the user inserts the foot.

[0005] Commonly, the sock is made of jersey knit, which is replaced near the proximal edge by a strip of higher elasticity knit to exert slight pressure and keep the sock in place. It is known to do this by using a ribbing pattern, for example 2-2 ribbing. Nowadays, materials including highly elastic fibers, for example elastane, are frequently used, which can be combined with a ribbing pattern.

[0006] However, very often the elasticity of this elastic knitted band is not enough to keep the sock in place, because it tends to relax and the sock ends up slipping into the shoe. In addition to being unsightly, the sock then no longer plays no longer its role of protection between the skin and the shoe, especially since the textile compresses towards the tip of the foot, causing an unpleasant sensation.

[0007] This problem is particularly feared by users of short socks. Indeed, invisible socks are generally used for aesthetic reasons by people who do not want them to appear outside of low-top shoes. They do not have the part rising above the ankle, which increases the risk of gradual slipping in the shoe when walking. This results in discomfort, or even the appearance of blisters due to the friction of the shoe directly on the user's skin. However, because they are hidden in the shoe, it is impossible to put them back in place without first taking off the shoes.

[0008] Various solutions have been proposed to improve the hold of socks. For models with a high part, it has been proposed to use a strap that can be adjusted around the leg after putting on the sock, or an additional elastic bracelet. For example, FR 746 959 proposes fixing a strip under the upper edge of the sock and inserting a rubber ring into it. These devices are not suitable for holding mini-socks.

[0009] In the particular case of mini-socks, the elastic knitted band described above is placed around the foot, tightening the sock slightly on the instep. It has been proposed to coat this band with a silicone compound adhering to the skin. Other models recommend the use of smaller adhesive elements, for example in the form of pads placed at the back of the sock. However, the sticky feeling of these coatings can be unpleasant, especially since mini-socks are generally worn in summer. Their adhesion is greatly reduced due to perspiration and it diminishes over time with washing due to the erosion of the adhesive surface.

[0010] It has also been suggested to place a silicone element or other adhesive material between the shoe and the sock, at the level of the Achilles tendon, so as to increase the friction opposing slipping. However, since the area concerned is not very large, the effectiveness remains insufficient. It is further reduced in the event of perspiration or rain and after a few washes.

[0011] Still other means have been devised to remedy the undesirable slipping of socks. WO 2018 / 082398 proposes placing straps under the sock at the front and back of the sock, and engaging the inner sole of the shoe therein so as to keep the sock in place.

[0012] Document WO 2015 / 184195 describes a device designed specifically for holding a sock worn with a high-heeled shoe. It comprises a flexible strap extending from the rear area of ​​the sock, which can be wrapped in loops around the heel of the shoe.

[0013] Thus, many devices have been described and are known to professionals. However, none has to date given complete satisfaction. However, invisible socks are popular with both women and men, who wish to combine comfort and elegance in their clothing. This craze has become widespread with the increase in the wearing of light, low-top shoes, such as tennis shoes, sneakers, loafers, espadrilles, etc., made of canvas or other light textiles. The present invention therefore aims to provide a sock, and in particular an invisible sock, which overcomes the aforementioned drawbacks.

[0014] The primary aim of the present invention is to provide a device for holding a sock in place on the foot and leg of a user. In particular, it is sought to prevent the socks from coming off the heel and to prevent them from forming bulges at the front of the shoe. A particular aim is to provide a solution suitable for holding socks that do not come up to the ankle, such as invisible ankle socks. Another aim of the invention is to provide a decorative accessory that can be coordinated with the color and style of the shoe or other clothing of the user. Another aim is to provide a device that is comfortable and convenient to wear, or even makes it easier to put on the socks. Finally, it is desired that this device be economical and easy to produce, both in industrial and artisanal production.

[0015] It is to meet these objectives and aims that the sock which is the subject of the present application was designed. It comprises a flexible element mounted on its rear part comprising reversible connecting means to the rear part of a shoe, itself being provided with receiving means capable of cooperating with the connecting means of the sock. The flexible element is arranged to protrude from the shoe and can be folded down against it. The connecting and receiving means are placed opposite each other so as to be associated when the flexible element is folded down, and thus to maintain the sock in the appropriate position.

[0016] More specifically, the invention relates to a sock for shoes with a low or high upper, made of tubular knit defining a main axis Ap, comprising: - a footwear part capable of covering the foot of a user, provided with a closed distal zone intended to receive the toes and a rear part having a curved zone intended to receive the heel of the user, said curved zone comprising a lower area and a rear area intended to be placed respectively under the heel and against the calcaneal region of the foot of the user, and - a proximal part capable of covering at least the base of the ankle of said user, and offering a circular opening through which the foot can be engaged, the sock comprising at least one flexible tab mounted on said proximal part above the rear area by a fixing means allowing pivoting of said at least one leg between a raised position and a lowered position, said at least one leg comprising reversible connecting means capable of cooperating with complementary receiving means provided on the upper of said shoe.

[0017] Conventionally, the sock is made from a circular knit or round knit that creates a seamless tube, which is inflected by a bulge provided to receive the heel of a user. The knit tube defines the curved main axis Ap of the sock, inflected in the same way as the latter.

[0018] Since socks are shaped to fit the human body, anatomical vocabulary is often extended to describe their various parts. Similarly, their orientation is often defined as they are worn. Thus, we commonly speak of the foot and heel of a sock, or the bottom and top of the sock.

[0019] To avoid ambiguities in the remainder of this description, the part of the sock covering the foot will be referred to as the "footwear part". This includes the toe of the sock, which is a closed distal area designed to receive the toes, and opposite, a so-called posterior part having a curved area designed to receive the user's heel. The curved area determines the orientation when putting on the sock, and consequently the region placed under the anatomical heel is designated "lower range" and that placed against the calcaneal region "rear range". It is specified, however, that, for the sake of simplicity and clarity, reference may be made in the description below to the orientation of a sock as worn by a person standing upright.

[0020] In particular, the term "proximal part" refers to the part of the sock located in the extension of the footwear part, above it. The proximal part can have different lengths depending on the model of the sock. It can cover the leg in whole or in part (as in a stocking or a knee-high), or go up to the ankle (as in a sock). At the very least, it encloses the base of the ankle, i.e. a region located under the malleoli. In the latter case (which corresponds to a mini-sock), the sock is formed of the footwear part and a simple collar acting as a proximal part, knitted over a few millimeters or a few tens of millimeters in height.

[0021] The sock according to the invention comprises one or more flexible tabs mounted on the proximal part above the rear area. In other words, each tab is fixed to the rear of the proximal part, at a greater or lesser height depending on the model of shoe which will be associated with the sock. It is thus placed projecting towards the rear of the leg, once the sock is put on. If it is a mini-sock, each tab will be fixed nearby, that is to say a little above the rear area of ​​the footwear part. It will thus be placed projecting towards the rear, at the level of the Achilles tendon (or calcaneal tendon), once the sock is put on. It is mounted by a means of fixation allowing it to pivot between a raised position and a lowered position, which implies a substantially horizontal mode of fixation (or perpendicular to the Ap axis) allowing said tab to be moved easily up and down. For example, a tab can be fixed by a horizontal seam (allowing a fold of said tab along a line orthogonal to the Ap axis). The tab being flexible, it easily changes conformation when it is turned down or up.

[0022] Each tab comprises connecting means capable of cooperating with complementary receiving means provided on the upper of a shoe. The connection is reversible, in that the connecting means and the receiving means can be associated and dissociated at will by the user, without the need for a tool. It is understood that when a tab is lowered, it comes to overlap on the outside of the shoe, the fixing means and the receiving means then being opposite each other to be able to cooperate. It also goes without saying that the fixing means are arranged on the face of each tab intended, when it is lowered, to come into contact with the shoe.

[0023] The sock which is the subject of the invention is designed to be worn under low-top shoes, that is to say shoes covering only the foot, and possibly also partly the ankle, or under high-top shoes, which cover the leg or part of it, excluding shoes without a top (barefoot, babouches, flip-flops, etc.). As will be explained later, ordinary shoes can be used, after having been equipped with the complementary receiving means of the connecting means with which the socks are provided, this operation being able to be carried out in an industrial, artisanal or domestic setting. As a result, the socks according to the invention can be manufactured and marketed independently of the shoes with which they will be worn. They can also be associated with various shoes in different combinations.

[0024] The tabs that can be used for the socks according to the invention can take various forms. A single, relatively long tab can be provided, or several shorter tabs arranged with a gap between them.

[0025] In particular, the sock may comprise a single tab fixed to a segment of the proximal part of the sock, with a length of 3 cm to 15 cm, preferably 5 cm to 12 cm. The fixing may be done for example by a seam, carried out continuously or discontinuously, with a straight stitch or elastic stitches, for example a zig-zag stitch or others.

[0026] Certain models of socks, generally invisible ankle socks, may have a tab integrated by design into the knit, as an extension of the distal part at the rear end. This tab may be used in the context of the present invention. Indeed, it may act as a flexible tab whose attachment to the rear end is ensured by the mesh. A connecting means may be attached to it, as will be described later.

[0027] Thus, according to an interesting characteristic, the sock which is the subject of the present invention comprises a tab fixed by a seam or by a mesh on a segment of the proximal part of said sock, with a length of 3 cm to 15 cm.

[0028] According to an alternative characteristic of the sock which is the subject of the invention, it may comprise at least two tabs each fixed to a segment of the proximal part of the sock by a seam with a length of 1 cm to 5 cm, preferably 2 cm to 3 cm.

[0029] Care should be taken to ensure that the tabs are arranged so as not to hinder the flexion of the ankle, therefore placed essentially on the posterior region of the proximal part with a moderate extension on the lateral regions. However, in the case where the sock is intended to be worn with a high-top shoe, this constraint is limited. Furthermore, we have seen that when a tab is lowered, it comes to overlap the outside of the shoe. The overlap must be sufficient so that the connecting means can be correctly maintained, while remaining lower than the height of the upper of the shoe. The tabs may in this context have a height of a few centimeters, for example between 2 cm and 6 cm.

[0030] Preferably, according to the invention, the tab(s) are each formed from a piece of soft leather or a piece of fabric. The leather may be natural or artificial, just as the fabric may be made from natural or synthetic fibers. In all cases, a material is chosen that offers the flexibility required for the tab to be able to be lowered and raised easily and repeatedly, but whose elasticity along the axis Ap is negligible with respect to the forces exerted, in order to avoid stretching that would be detrimental to keeping the sock in place, particularly when the user walks. In particular, when using fabric, it is recommended to fix the tab along the straight grain.

[0031] Each tab must adopt a shape that allows its assembly on the sock as well as its connection to the shoe. It can advantageously be designed by introducing aesthetic criteria. Conveniently, it will have a straight side fixed to the sock, while the movable part can adopt more varied contours. For example, it can take the form of a rectangular strip, a square, rounded, or triangular piece. The edges can be smooth, notched, wavy,... Of course, the choice of color, texture, or possible patterns can also contribute to embellishing the whole.

[0032] In another embodiment, the sock according to the invention comprises at least two tabs each formed from a flexible strap fixed to the proximal part of the sock, at a distance from each other of 3 cm to 15 cm, preferably of 5 cm to 12 cm. A strap may be made for example of a double cord, having a loop at its end which acts as a means of connection to a receiving member of the shoe. As previously, these tabs may have a height of a few centimeters, for example between 2 cm and 6 cm.

[0033] According to a preferred characteristic of the sock according to the invention, whatever the type of tabs chosen, the tab(s) are arranged on the proximal part of the sock symmetrically with respect to the main axis Ap. In this way, a balanced distribution ensures effective support of the sock, while providing a harmonious appearance.

[0034] Advantageously, the connecting means provided on the leg(s) of the sock are also arranged symmetrically, both with respect to the leg which carries them and with respect to the axis of the sock. A single leg may have at least two, whereas in the case where there are several legs, each may be equipped with a single connecting means.

[0035] These connecting means cooperate with receiving means, the assembly being able to be of different types, generally consisting of a male part cooperating with a female part. The most convenient is certainly the press stud, but other systems can be used, such as button-buttonhole, button-strap, loop and hook-and-eye, eyelet and nipple, gripping strips, or other connections. Note that in certain cases, the male and female parts can act indifferently as connecting means or receiving means. It is their location on a tab or on the upper of the shoe which will determine their role.

[0036] For example, the two male and female parts of a snap fastener can be placed on either the tab or the upper of the shoe, just like the two parts of a hook-and-loop strip. In the case of clasps, the hook will preferably be placed on the tab so that the more discreet loop is installed on the upper. Finally, the buttons will rather be mounted on the upper of the shoe, a buttonhole or a braid can be more easily made on the tab. Other methods of connection can be used, as long as they meet the desired purpose.

[0037] Thus, according to a characteristic of the sock which is the subject of the invention, the connecting means with which the leg(s) of said sock are provided to cooperate with means for receiving the upper of the shoe are chosen from: the male parts and female snap fasteners, buttons and buttonholes or cord, loops and hooks, eyelets and nipples, hook and loop fasteners.

[0038] The sock which is the subject of the invention may be manufactured according to one of the numerous techniques known to those skilled in the art. It may be knitted from any material suitable for the intended use, from natural yarns, for example wool, cotton, or silk, or from synthetic fibers, for example polyester, polyamide, nylon, elastane, or even from mixed fibers. It may belong to any category, in particular be more or less long, so as to rise more or less high on the user's leg. According to a characteristic of the invention, the sock may be a stocking, a knee-high, a sock, or a mini-sock.

[0039] It is noted that the invention is particularly suitable for mini-socks whose proximal part is capable of covering only the base of the user's ankle, and which have a strong tendency to slip under the foot because they are not held on the leg.

[0040] As explained above, the sock according to the invention is designed to be worn under a shoe to which it will be held by connecting means cooperating with receiving means.

[0041] This is why the second subject of the invention is a footwear assembly comprising i) a sock according to the invention and ii) a shoe with a low or high upper, each comprising reversible connecting means and complementary receiving means, capable of cooperating when said at least one flexible tab with which the sock is provided is in the lowered position on the upper of said shoe.

[0042] As explained above, the user will associate a type of sock with the model of shoe that he wishes to wear, by putting on a sock which is provided with connecting means placed at the appropriate height relative to the upper of the shoe. The design of the sock according to the invention in fact offers him complete latitude in the choice of his shoes. This faculty applies both to the model of shoes, and with regard to the materials from which they are made. Indeed, shoes made of any type of material can be chosen, natural or synthetic textile, leather, polymer or others, or of composite material combining several of these materials. Care will be taken, however, that the upper is capable of receiving and maintaining receiving means, themselves being judiciously chosen.

[0043] This is why, advantageously, in the footwear assembly according to the invention, the shoe can be chosen in particular from tennis shoes, sneakers, espadrilles, moccasins, shoes, ankle boots, booties, boots.

[0044] It is easy to understand that this footwear set will generally come in pairs, with one shoe adapted to the right foot and another adapted to the left foot, while the two socks can be undifferentiated. The symmetry of the connecting means with respect to the main axis Ap is therefore clearly preferred.

[0045] An original aspect of the invention is that a user can make a footwear set himself from shoes belonging to his wardrobe and the socks described above, which he can also make himself. He will simply have to install on his shoes receiving means complementary to the connecting means provided on the socks. To meet this option, a kit is proposed for the assembly of a footwear set according to the invention, comprising a sock as previously described, and receiving means complementary to the connecting means with which the sock is provided, said receiving means being capable of being fixed to a shoe with a low or high upper, so that when said at least one flexible tab is lowered onto the upper of said shoe, said receiving means and said connecting means cooperate with each other.

[0046] It should be noted that a user can also make the socks described above himself, by attaching one or more tabs to a pair of common socks. It can thus be seen that the footwear assembly according to the invention is economical and easy to make, whether in industrial, artisanal or personal production.

[0047] As appears from reading the present description, the sock which is the subject of the invention constitutes not only an article which is convenient to wear and comfortable to wear, but also a decorative accessory, which can be coordinated with the color and style of the user's shoe or other clothing.

[0048] The present invention will be better understood and relevant details will appear, in the light of the description which will be given of embodiments, in relation to the appended figures.

[0058] EXAMPLE 1: Sock of the prior art

[0059] As shown in [Fig.l], a sock 100 is intended to cover the foot 200 and the leg 220 of a user. The foot 200, comprising at its distal end, the toes 210 and at its posterior part, the heel 211. It is separated from the leg 220 by the ankle 230 easily identifiable by the position of the malleoli 212, behind which is the calcaneal tendon 213 (or Achilles tendon) inserted on the calcaneus 214. The calcaneal region thus corresponds to the rear of the heel 211.

[0060] A sock extends along a main axis Ap and comprises in a known manner a footwear part 1 which will cover the foot 200 of the user, and a distal part 2 covering all or part of the leg 220, or at least the base of the ankle 230 and offering a circular opening 21 for introducing the foot and which will rest on the leg 220 or the ankle 213. The footwear part is closed at its distal end 11 receiving the toes 210, and is curved at the heel 211, with a lower area 13 placed under the heel 211, and a rear area 14 placed against the calcaneal region of the user's foot. The socks according to the invention adopt this basic structure.

[0061] EXAMPLE 2: Mini-sock with a connecting tab and associated shoe

[0062] The embodiment of the invention shown in [Fig.2a] is a mini-sock designed to be invisible when worn under a low-top shoe. It comprises a shoe part 1 and a proximal part 2 about one centimeter high, capable of covering only the base of the user's ankle. A tab 3, of rectangular shape, is fixed to the proximal part 2, on its external face, by a stitch 15 made with a zig-zag stitch, following the edge of the proximal part 2, substantially horizontal.

[0063] It is presented here in the raised position, which highlights that it can be grasped to facilitate the donning of the sock. It can thus be folded down by a fold following the line of this stitching. It is positioned symmetrically so as to extend along the proximal part 2, on either side of the rear area 14, over approximately 4 cm on each side. It is provided with two connecting means 31, in this case the female parts of press studs, placed a short distance from the lateral edges of the tab.

[0064] These connecting means 31 are provided to cooperate with receiving means 41 fixed on a low-top shoe 300, as shown in [Fig.2b]. These are the male parts of press studs corresponding to the female parts present on the tab 3. The user, having put on the sock, taking care to keep the tab 3 in the raised position, inserts his foot into the shoe, then lowers the tab 3 which covers the shoe on the external face. All that remains is to combine the male and female parts of the press studs, to obtain a secure attachment preventing the mini-sock from slipping. [Fig.2c] shows the result of the assembly seen from the rear, which provides a decorative element to the shoe, without revealing its functional aspect.

[0065] The elements described above constitute a footwear assembly according to the invention. The shoe may be made of leather or canvas, and the attachment of the press studs may be carried out in series so that the sock-shoe assembly is marketed ready to wear. It may also be made to order, by a shoemaker or by an individual, using a suitable tool such as pliers designed for this purpose and available commercially.

[0066] EXAMPLE 3: Mini-sock with three connecting tabs

[0067] [Fig.3] shows a mini-sock whose general structure is similar to that described in example 2. It is distinguished by the fact that it is provided with three tabs 3 fixed on the proximal part 2. The tabs 3 are separated from each other by a few centimeters and each extends over approximately 2 to 3 centimeters. It may be advantageous for the middle tab to be more extended than the two lateral tabs. Each is provided with a connecting means 31, in this case metal hooks intended to cooperate with receiving means 41 provided on the shoe to be worn with said mini-sock. The receiving means 41 may be, for example, metal, textile or leather buckles, or eyelets.

[0068] EXAMPLE 4: Mini-sock with two connecting tabs

[0069] [Fig.4] shows a mini-sock whose general structure is similar to that described in example 2. It is distinguished by the fact that it is provided with two tabs 3 fixed on the proximal part 2, taking the form of two flexible straps 3a obtained for example by joining two cords. Each strap 3a has at its free end, a loop acting as a connecting means 31. It can in fact be passed around a receiving member 41 such as a hook or a nipple.

[0070] EXAMPLE 5: Long sock with a low connecting tab

[0071] The embodiment of the invention shown in [Fig.5a] is a knee-high or high sock comprising a single connecting tab 3. It comprises a shoe part 1 and a long proximal part 2 capable of covering part of the user's leg. A tab 3 is fixed to the proximal part 2, on its external face, just above the rear area 14, by a substantially horizontal stitching 15. As in the previous example, it is positioned symmetrically so as to extend on either side of the rear beach 14, over several centimeters on each side. Two connecting means 31 with receiving means 41 of the upper of a low-top shoe are provided, in this case gripping strips.

[0072] EXAMPLE 6: Long sock with a high connecting tab

[0073] The embodiment of the invention shown in [Fig.5b] is a knee-high sock comprising a single connecting tab 3. It is similar to the sock of the previous example, except for the position of the tab 3 which is fixed to the proximal part 2, clearly above the rear area. This sock is suitable for being worn with boots rising to the level of the user's calf.

[0074] EXAMPLE 7: Sock with a high connecting tab

[0075] The embodiment of the invention shown in [Fig.5c] is a sock, intended to cover the user's ankle. It comprises, as previously, a single connecting tab 3, which is placed at the upper edge of the proximal part. This sock is suitable for being worn with ankle boots or high-top sneakers.
