Description

Title of the invention: Knitted article comprising at least one protuberance

[0001] The present invention relates to a knitted article of the type comprising at least two knitting yarns and at least one weft yarn, said knitted article comprising at least a first zone, in which the two knitting yarns are knitted together to form a sheet, the weft yarn being laid tautly in said sheet.

[0002] Such a knitted article finds applications more particularly in the field of compressive textiles for medical or sports use.

[0003] It is known to produce a wide variety of textile articles with one or more protruding areas to perform various functions on a limb of a user of such an article.

[0004] Thus, it is for example known to produce a device for treating cutaneous and subcutaneous conditions in the form of a strip or sleeve of textile material formed from two textile sheets holding between them a plurality of foam blocks forming protuberances in the treatment device. These protuberances are arranged to generate a massaging effect on the skin of a patient in order to promote surface microcirculation at the level of a superficial cutaneous network to, for example, reduce edema. Document EP 1 926 458 describes for example such a device for treating cutaneous and subcutaneous conditions.

[0005] Orthoses, such as a knee brace or an ankle brace, comprising a tubular body made of textile material and one or more inserts, forming one or more protrusions in the orthosis, are also known. Such orthoses are for example described in standard NF S97-117 (May 2022) entitled “Medical compression orthoses - Technical specifications”. The insert, for example a patellar insert in the case of a knee brace, for example made of silicone, thermoplastic elastomer (TPE) or foam, makes it possible for example to improve the support and / or to orient the joint of the limb receiving the orthosis.

[0006] Other textile articles receive, for example, gel cushions inserted into the body of the textile article in order, for example, to improve the comfort of the user of the textile article and / or in order to apply a particular treatment to the user's skin.

[0007] Such articles are complex to produce because the protruding elements must be integrated into the textile article, for example during the sewing or knitting of the textile article or by inserting the elements between two textile sheets which are then assembled together to ensure the elements are held in place.

[0008] One of the aims of the invention is to provide a knitted article comprising one or more protruding zones which can be integrated in a simple manner into the knitted article.

[0009] To this end, the invention relates to a knitted article of the aforementioned type, comprising at least a second zone, in which the two knitting yarns are knitted separately and are spaced apart from each other to form a pocket between them, the weft yarn being received in said pocket freely and loosely, the second zone forming a protuberance extending projecting from the sheet formed by the first zone in a thickness direction going from one face to the other of said sheet.

[0010] Thus, in the knitted article according to the invention the protrusion(s) are directly formed by the yarns constituting the knitted article so that it is not necessary to provide additional elements to be fixed on or in the knitted article. A finished knitted article can thus be obtained in a single knitting step with a single knitting machine. Furthermore, the shape, dimensions, location and / or number of protrusions can be simply adjusted by an adjustment of the knitting machine or by means of a control program of the knitting machine allowing the number of needles and / or the number of knitting rows to be changed, which makes it possible to change the size of the protrusion(s) in the knitted article.

[0011] The knitted article according to the invention may further comprise one or more of the following characteristics, taken in isolation or in any technically conceivable combination: - the weft thread is elastic; - the weft thread is inelastic; - at least one of the two knitting threads is elastic; - the protuberance formed by the second zone extends in a shape elongated on at least one of the faces of the sheet formed by the first zone; - the shape of the protuberance extends along a closed contour extending around a first zone or an opening passing through the knitted article in the thickness direction, said closed contour being surrounded at least in part by a first zone; - the knitted article is knitted to form an orthosis, said orthosis comprising a substantially tubular body formed by the first zone and at least one insert extending projecting from the body formed by at least a second zone; - the knitted article comprises a plurality of second zones spaced apart from each other and connected to each other by one or more first zones; - the knitted article is knitted to form a device for treating cutaneous and subcutaneous conditions comprising alternating areas hollow formed by one or more first zones and raised zones formed by several second zones; - a first knitting yarn of the knitting yarns is knitted in a 1 and 1 rib structure and a second knitting yarn of the knitting yarns is knitted in a reverse jersey structure or in a 1 and 1 rib structure in the first zone; - the first knitting yarn is knitted in a reverse stockinette stitch structure and the second knitting yarn is knitted in a right stockinette stitch structure in the second zone; - the knitted article further comprises a third knitting yarn, said third knitting yarn being knitted with both knitting yarns in the first zone and being knitted with only one of the knitting yarns in the second zone or being freely and loosely laid with the weft yarn in the pocket in the second zone.

[0012] Other aspects and advantages of the invention will appear more clearly on reading the description which follows, given solely by way of non-limiting example, and made with reference to the appended drawings in which:

[0020] [Fig.8] - [Fig.8] is a schematic representation of the knitting of the knitted article of [Fig.6] in the second zone of the knitted article,

[0021] [Fig.9] - [Fig.9] is a schematic representation from above of a knitted article according to the invention forming an orthosis, and

[0022] [Fig. 10] - [Fig. 10] is a schematic top view of a knitted article according to the invention forming a device for treating skin and subcutaneous conditions.

[0023] With reference to [Fig. 1], a knitted article 1 is described comprising at least a first zone 2 and at least a second zone 4. Such a knitted article 1 is more particularly intended for a medical or sporting application, as will be described in more detail later.

[0024] The knitted article 1 has a reverse side 6, intended to be applied against the skin of a user wearing the knitted article 1, and a right side 8, intended to be turned outwards when the knitted article 1 is worn. The thickness of the knitted article 1 is defined in the direction from the reverse side 6 to the right side 8, called the thickness direction, as being the distance separating the reverse side 6 and the right side 8.

[0025] In the first zone 2, the knitted article 1 is formed by a sheet. Thus, in the first zone 2, the reverse side 6 and the right side 8 are substantially parallel. In the first zone 2, the knitted article 1 has, for example, a thickness substantially between 0.5 mm and 3 mm.

[0026] In the second zone 4, the knitted article 1 comprises a protuberance 10 extending in projection from the sheet forming the first zone 2 in the direction of thickness. By projection from the sheet, it is meant that the protuberance 10 extends in projection from at least one of the faces of the first zone 2 in the direction of thickness, that is to say in projection from the reverse face 6 and / or from the right face 8. According to the embodiments shown in the figures, the protuberance 10 extends in projection from the reverse faces 6 and right faces 8 of the sheet. In the second zone 4, the knitted article 1 has a thickness, corresponding to the thickness of the protuberance 10, for example substantially between 5 mm and 25 mm.

[0027] The first and second zones 2, 4 are knitted from the same yarns so that they are integral with each other. More particularly, the knitted article 1 comprises at least two knitting yarns or mesh yarns, namely a first knitting yarn 12 and a second knitting yarn 14, and at least one weft yarn 16. In the figures, the first knitting yarn 12 is shown in regular lines, the second knitting yarn 14 in dotted lines and the weft yarn 16 in bold lines.

[0028] As will be described in more detail later, the first knitting yarn 12 and the second knitting yarn 14 are knitted together in the first zone 2, i.e. they cross in the first zone 2. In other words, in the first zone 2, one of the yarns is knitted partly on the front needle bed and partly on the back needle bed and the other yarn is knitted on the back needle bed. Thus, in the first zone 2, the first and second knitting yarns 12, 14 form the web. In the second zone 4, the first knitting yarn 12 and the second knitting yarn 14 are knitted separately from each other, the first knitting yarn 12 forming the reverse side 6 of the protuberance 10 and the second knitting yarn 14 forming the right side 8 of the protuberance 10.

[0029] The first knitting yarn 12 may be an elastic or non-elastic yarn having a count, for example, between 17 dtex and 680 dtex. By elastic, we mean a yarn that can be stretched under the effect of an external stress intended to lengthen the yarn and that returns to its initial length when this stress ceases to be applied. An elastic yarn has, for example, a maximum elongation before breaking greater than or equal to 300%. By non-elastic, we mean a yarn that is substantially inextensible under the effect of an external stress intended to stretch the yarn. A non-elastic yarn has, for example, a maximum elongation before breaking less than or equal to 100%.

[0030] A non-elastic thread is, for example, a thread formed from one or more of the following textile materials: - Natural fibers, such as cotton, wool, linen, hemp, etc.; - Fibers made of artificial materials, such as viscose, etc.; - Synthetic fibers, such as polyamide, polyester, polypropylene, etc.

[0031] An elastic yarn is for example a single covered yarn, a double covered yarn or a structure of the “core spun yarn” type.

[0032] In the case of a single-gapped or double-gapped yarn, the wrapping operations are carried out by a spiral winding technique around an elastic core yarn, or by intermingling by air jet around an elastic core yarn. The core yarn is for example made of one or more elastane or latex filaments, the count of which is for example between 17 dtex and 475 dtex. The covering yarn(s) are formed from one or more of the following textile materials: - Natural fibers, such as cotton, wool, linen, hemp, etc.; - Fibers made of artificial materials, such as viscose, etc.; - Synthetic fibers, such as polyamide, polyester, polypropylene, elastane, etc.

[0033] In the case of a “core spun yarn” type structure, the core yarn is for example made of an elastane or latex filament, the yarn count of which is between 17 dtex and 475 dtex. The fiber sheets surrounding the core are for example formed of one or more of the following textile materials: - Natural fibers, such as cotton, wool, linen, hemp, etc.; - Fibers made of artificial materials, such as viscose, etc.; - Synthetic fibers, such as polyamide, polyester, polypropylene, etc.

[0034] The second knitting yarn 14 may also be an elastic or non-elastic yarn, examples of which are given above.

[0035] According to different embodiments, the first and second knitting yarns 12, 14 may be identical or different from each other. It should be noted, however, that at least one of the first and second knitting yarns 12, 14 is an elastic yarn.

[0036] The weft yarn 16 may also be an elastic yarn or a non-elastic yarn depending on the function of the knitted article 1. According to an embodiment in which the weft yarn 16 is elastic, the weft yarn 16 has for example a count substantially between 300 dtex and 1500 dtex. More particularly, the weft yarn 16 is for example a double-wrapped yarn, comprising a core formed from an elastane monofilament having a count of 1280 dtex and two polyamide wrapping yarns. When the weft yarn 16 is non-elastic, the weft yarn 16 has for example a count between 300 dtex and 1500 dtex and is for example a yarn formed from one or more of the following textile materials: - Natural fibers, such as cotton, wool, linen, hemp, etc.; - Fibers made of artificial materials, such as viscose, etc.; - Synthetic fibers, such as polyamide, polyester, polypropylene, etc.

[0037] According to various embodiments, in particular those shown in Figs. 1 to 5, the knitted article further comprises at least one third knitting yarn 18, which may or may not be elastic. In the case of a non-elastic third knitting yarn 18, the third knitting yarn 18 is, for example, a non-elastic yarn as described previously for the first and second knitting yarns 12 14. In the case of an elastic yarn, the third knitting yarn 18 is, for example, an elastic yarn as described previously for the first and second knitting yarns 12 14. In the figures, the third knitting yarn 18 is shown in thin lines.

[0038] As previously indicated and as shown in Figs. 2 and 7, in the first zone 2, the web is formed by knitting the first and second knitting yarns 12, 14 together. Optionally, when present, the third knitting yarn 18 is also knitted with the first and second knitting yarns 12, 14 to form the web in the first zone 2, as shown in [Fig. 2]. As shown in Figs. 2 and 7, in the first zone 2, the weft yarn 16 is laid taut in the web, being more particularly held in place in the web by the first knitting yarn 12, as will be described in more detail later.

[0039] In the second zone 4, the first and second knitting yarns 12, 14 are knitted separately from each other and spaced apart from each other, so as to define between them the pocket 10, receiving the weft yarn 16. More particularly, the first knitting yarn 12 forms the reverse side 6 of the knitted article 1 in the second zone 4 and the second knitting yarn 14 forms the right side 8 of the knitted article 1 in the second zone 4. In the pocket 10, the weft yarn 16 is received freely and loosely so as to form a padding of the pocket 10, as shown in Figs. 1, 4 and 6. By "free and loose manner" is meant that the weft yarn 16 fills the pocket 10 by forming folds inside this pocket 10, the length of weft yarn 16 present inside the pocket 10 as well as the elastic or non-elastic nature of the weft yarn 16 making it possible to adjust the thickness and flexibility of the pocket 10.In this way, the knitted article 1 comprises a pad in the second zone 4, this pad being able to provide a massaging effect on the skin of a user or being able to form an insert for a joint, as will be described in more detail later.

[0040] When a third knitting yarn 18 is provided, this is, according to a first embodiment shown in Figs. 1 and 3, knitted with the first knitting yarn 12 in the second zone 4 so as to form with the first knitting yarn 12 the reverse side 6 of the knitted article 1 in the second zone 4. According to a second embodiment, shown in Figs. 4 and 5, the third knitting yarn 18 is received freely and loosely with the weft yarn 16 in the pocket 10 so as to form a padding of the pocket 10 with the weft yarn 16 in the second zone 4 of the knitted article 1.

[0041] The knitting of the different yarns of the knitted article will now be described according to different embodiments.

[0042] According to a first embodiment, the knitting of which is shown in Figs. 2 and 3, the knitted article 1 comprises three knitting yarns 12, 14 and 18, the third knitting yarn 18 forming the reverse side 6 of the knitted article in the second zone 4 with the first knitting yarn 12 as described previously.

[0043] According to this embodiment, in the first zone 2, the knitting of which is shown in [Fig. 2], the first knitting yarn 12 is knitted according to a 1 and 1 rib structure and the second knitting yarn 14 is knitted according to a reverse jersey structure. The third knitting yarn 18 is also knitted according to a reverse jersey structure. This structure is produced by means of a knitting machine using n needles of the front needle bed and n needles of the rear needle bed. "n" corresponds to an integer number of needles and the choice of this number makes it possible to adjust the width of the first zone 2. As indicated previously, the weft yarn 16 is laid taut in the sheet thus formed taut by being laid between the front and rear needle beds of the knitting machine.

[0044] In the second zone 4, the knitting of which is shown in [Fig. 3], the first knitting yarn 12 is knitted in a reverse stockinette structure and the second knitting yarn 14 is knitted in a front stockinette structure. The third knitting yarn 18 is knitted in a back stockinette structure and forms, with the first knitting yarn 12, the reverse side of the knitted article 1 in the second zone 4. In the second zone 4, the first knitting yarn 12 and the third knitting yarn 18 are knitted using n' needles of the back bed and the second knitting yarn 14 is knitted using n' needles of the front bed. "n'" corresponds to an integer number of needles different from n and the choice of number makes it possible to adjust the width of the second zone 4. The length of the second zone 4 depends on the number of successive knitting rows.As previously indicated, the weft yarn 16 is deposited freely and loosely in the pocket 10 thus formed by being deposited between the front and rear needle beds of the knitting machine.

[0045] Such an embodiment makes it possible to vary the size of the protrusions, or studs, on one face thanks to the presence of an elastic knitted yarn. In addition, when three knitted yarns are provided, it is possible to have yarns of different colors in order to give a particular appearance to the knitted article.

[0046] According to a second embodiment, the knitting of the second zone 4 of which is shown in [Fig. 5], the knitted article 1 comprises three knitting yarns 12, 14 and 18, the third knitting yarn 18 forming the padding of the pocket 10 in the second zone 4 with the weft yarn 16 as described previously.

[0047] According to this second embodiment, the knitting of the first zone 2 is identical to that of the first zone 2 of the first embodiment described previously.

[0048] In the second zone 4, the first knitting yarn 12 is knitted in a reverse stockinette structure and the second knitting yarn 14 is knitted in a front stockinette structure. The third knitting yarn 18 is laid freely and loosely with the weft yarn 16 in the pocket 10 thus formed by being laid between the front and rear needle beds of the knitting machine. In the second zone 4, the first knitting yarn 12 is knitted using n' needles of the rear needle bed and the second knitting yarn 14 is knitted using n' needles of the front needle bed. The choice of n' makes it possible to adjust the width of the second zone 4. The length of the second zone 4 depends on the number of successive knitting rows.

[0049] Such an embodiment makes it possible to increase the thickness of the protuberance, or even its hardness.

[0050] According to a third embodiment, shown in Figs 6 to 8, the knitted article 1 comprises only the first knitting yarn 12, the second knitting yarn 14 and the weft yarn 16. In other words, the knitted article 1 does not comprise the third knitting yarn 18 described previously.

[0051] According to this embodiment, in the first zone 2, the knitting of which is shown in [Fig. 7], the first knitting yarn 12 and the second knitting yarn 14 are knitted according to a 1 and 1 dimension structure. This structure is produced by means of a knitting machine using n needles of the front needle bed and n needles of the rear needle bed. The choice of n makes it possible to adjust the width of the first zone 2. As indicated previously, the weft yarn 16 is laid taut in the sheet thus formed taut by being laid between the front and rear needle beds of the knitting machine.

[0052] In the second zone 4, the knitting of which is shown in [Fig. 8], the first knitting yarn 12 is knitted in a reverse stockinette structure and the second knitting yarn 14 is knitted in a front stockinette structure. The first knitting yarn 12 is knitted using n' needles of the rear needle bed and the second knitting yarn 14 is knitted using n' needles of the front needle bed. The choice of n' makes it possible to adjust the width of the second zone 4. The length of the second zone 4 depends on the number of successive knitting rows. As indicated previously, the weft yarn 16 is deposited freely and loosely in the pocket 10 thus formed by being deposited between the front and rear needle beds of the knitting machine.

[0053] The fact of having only two knitting threads makes it possible to reduce the thickness of the sheet in the first zone 2 and to lighten the knitted article obtained.

[0054] The knitted article 1 according to the invention can therefore be obtained by knitting on a single knitting machine, the number, shape and dimensions of the one or more second zones 4 relative to the first zone 2 being adjustable simply by varying the number of needles and the number of knitting rows to produce the first and second zones 2 and 4.

[0055] The knitted article 1 according to the invention can take several forms to perform different functions. An example of a knitted article 1 forming an orthosis is shown in [Fig. 9] and an example of a knitted article 1 forming a device for treating cutaneous and subcutaneous conditions is shown in [Fig. 10].

[0056] In the case of an orthosis, the knitted article 1 comprises a tubular body 20 formed by a first zone 2 and at least one insert 22 extending projecting from the body 20 and formed by a second zone 4. The first and second zones 2 and 4 are produced according to one of the embodiments described previously. The weft yarn 16 is elastic.

[0057] In the case of a knee pad, as shown in [Fig. 9], the insert 22 has an elongated shape and a closed contour extending in projection towards the outside of the knitted article so as to form a patellar insert. Thus, in this case, the insert 22 extends mainly in projection on the right side face 8 of the knitted article 1. The insert 22 has for example a substantially ovoid or ellipsoidal shape surrounded at least in part by a first zone 2. The insert 22 surrounds an opening 25 passing through the body 20 in the direction of thickness, the opening 25 being intended to receive the kneecap of a user having put on the orthosis. It is understood that the insert 22 may have another shape and have varied dimensions adapted to different sizes of orthosis. It is understood that such an orthosis may have other second zones to form other types of insert and / or that the closed contour of an insert may surround a first zone 2 of the knitted article 1.

[0058] The knitted article 1 can also be used to form an ankle brace for example. In this case, several inserts are for example provided to form malleolar inserts extending in projection on the reverse face 6 of the knitted article around the ankle of a user having put on the orthosis. Such inserts are for example in the form of ribs extending in projection from the reverse face 6 of the knitted article in order to be applied against the skin of a user, the ribs being surrounded and connected together by one or more first zones 2 of the knitted article 1.

[0059] Generally speaking, in the case of an orthosis, the second zone(s) 4 have a hardness, on the reverse side 6 and / or on the right side 8, of between 25 sh 00 and 85 sh 00, in accordance with standard NF S97-117 of May 2022.

[0060] According to the example shown in [Fig. 10], the knitted article 1 comprises an alternation of hollow zones 24 formed by one or more first zones 2 and raised zones 26 formed by several second zones 4. In other words, according to this embodiment, the knitted article 1 has several second zones 4 spaced from each other and connected to each other by one or more first zones 2. The second zones 4 form pads extending in projection mainly on the reverse face 6 of the knitted article 1 so as to be applied against the skin of a user using the device for treating cutaneous and subcutaneous conditions.Such a knitted article 1 is in the form of a band or a sleeve and the pads can have various dimensions and shapes by adjusting the knitting machine as well as according to the knitting and weft yarns chosen, these yarns being characterized in particular by their count, their elastic or non-elastic behavior, or even their tension under a given elongation. The weft yarn 16 can be elastic or non-elastic.

[0061] More particularly, when the weft yarn 16 is elastic, the treatment device is deformable and exerts a relatively constant level of pressure if the volume of the user's limb covered by the treatment device varies little. When the weft yarn 16 is non-elastic, the treatment device is restraining, that is to say it exerts a pressure which can vary greatly even with a small variation in the volume of the user's limb covered by the treatment device.

[0062] In the case of a compressive sleeve, the knitted article more particularly has a substantially trapezoidal shape with pads of spherical or random shape with different right and wrong sides. The hardnesses of each of the sides are adjustable. For example, the compressive sleeve has a right side with a hardness of 36 sh 00 and a wrong side with a hardness of 52 sh 00. Alternatively, the right side has a hardness of 40 sh 00 and the wrong side has a hardness of 37 sh 00. The hardness and volume of the protuberances have a direct effect on the massage effect provided by the treatment device on the user's limb covered by this treatment device. More particularly, the higher the hardness and the larger the volume of the protuberances, the more the massaging effect will have a significant effect on the edema to be treated by the treatment device.Depending on the edema to be treated, it is possible to choose the side (from the front side and the back side) applied against the user's skin in order to apply a greater or lesser hardness to this edema.

[0063] In the case of a compression band, the knitted article more particularly has a substantially rectangular shape and the pads have a spherical or rectangular shape with rounded edges, as shown in [Fig. 10]. The front face of such a band has, for example, a hardness of 36 sh 00 and the reverse face has, for example, a hardness of 52 sh 00.

[0064] Those skilled in the art may refer to documents EP 1 926 458 and EP 3 128 968 to obtain different arrangements and different uses of such a device for treating cutaneous and subcutaneous conditions.
