    [0001] The present invention relates to a shoe lace. It relates more particularly to a shoe lace 100% silicone, ie made entirely of silicone, made to measure, which takes into account the change of pressure of a foot without compressing the latter, 5 in order to always maintain a pleasant foot and offer unparalleled comfort. The lace according to the invention finds a preferred application in the field of sports shoes, and in particular running shoes, including running nature or trail, and walking shoes, and can also be considered for city shoes, 10 safety shoes, climbing shoes, etc. In the field of lacing shoes, it is known to use laces fabric (polyester, nylon, cotton). These laces generally have two different aspects: round or flat, it being understood that a round lace is a substantially circular cross-section lace and a flat lace is a flat, generally rectangular cross-section lace. It is also known to use another lace model, namely a round elastic lace made of rubber, generally used by athletes who run long distances running. The first example of a fabric lace, however, provides no comfort for the foot. Indeed, during the day, or during a sports activity, the pressure of the foot increases. This lace fabric will make its support unpleasant, and at the end of the day will be observed compression marks on the top of the foot, called "kick". The second example of rubber elastic lace will compress the foot even more because the mechanical return of rubber elastic is much stronger than the pressure of a foot. In other words, the rubber laces have the disadvantage of compressing the foot too strongly because of a too high springback. Indeed, because of its elasticity, the wearer will tend to over-tighten his rubber laces which will strongly compress the foot in the shoe.
    [0002] Generally, as part of the practice of sport, or everyday, people tend to over tighten the laces of their shoes, especially to feel a frank hold of the foot. In addition, during a physical effort, such as running or walking, the foot naturally swells inside the shoe, by inflow of blood, and the lace is too tight on the foot. However, too tight laces on one foot, whether due to initial tightening too tight or subsequent swelling of the foot - especially during physical activity - cause a feeling of heavy legs due to insufficient venous and can cause several inconveniences: tingling, tingling, pain in the calves, cramps, tears, breakdowns or contractures. Too tight laces prevent the arch from moving freely and has the effect of impeding movement of the foot during activity.
    [0003] Too tight laces also stiffen the shoe even a sports shoe, with the potential consequence of a Morton's neuroma, also called "Morton's disease" which is a very painful condition that affects the interdigital nerve of the foot because of a foot too tight. Venous insufficiency is characterized by poor quality venous return, resulting in venous blood pressure. Many activities have the disadvantage of increasing stasis, such as extended standing and sports such as tennis, jogging, athletics and others. The human foot is an organ with bones and ligaments. The soles of the feet and the tips of the toes are provided with thousands of nerve endings per cm2. Twenty muscles control the movement. Physical activity causes reflex reactions that activate at least 400 pairs of muscles. The feet use seven points of support such as heel, pulp of the five toes and metatarsals, to support the weight of the body and to dampen the pressures.
    [0004] Finally, during the physical activity or the effort, the foot is transformed by inflating by influx of blood and with too tight laces one finds all its inconveniences. The present invention aims to overcome these disadvantages by proposing a lace that takes into account the change of pressure of a foot in activity to prevent compression and thus allow good blood circulation while maintaining the foot comfortably and offer unparalleled comfort . For this purpose the invention proposes to use one of the known materials for its shape memory, with a mechanical return studied, which is the silicone. Thus, the subject of the invention is a remarkable shoe lace in that it is made of 100% silicone. As described later, this lace can be of one form or several forms on the same lace, such as round, flat or oval, and is mostly made entirely of silicone, which will allow to take into account the change. pressure of one foot in activity to avoid any compressions and allow a good blood circulation. The invention more particularly relates to a lace with one or more different forms. According to a first embodiment, adapted especially for everyday use, the lace is of the same shape on the entire lace, ie has a constant cross section along the entire length of the lace. In this first embodiment, it is in particular conceivable that the lace is flat in its entirety, that is to say that the lace is of constant and flat cross section over its entire length; the flat shape being adapted to provide comfort on the kick. According to one possibility, the ends of the lace have an angle of 30 ° to facilitate the passage of the lace in the holes of the shoe, that is to say that the ends of the lace are beveled at an angle of 30 °.
    [0005] According to another possibility, in this first embodiment, the lace is made by extrusion, in other words according to a process for extruding silicone material. According to a second embodiment, the lace has several forms on the same lace, such a lace being particularly studied for adapted sports disciplines. In this second embodiment, it is quite obvious that the lace has several shapes means that the lace has several parts (or sections or segments) of distinct shapes, that is to say of distinct transverse sections. In a particular embodiment, the multi-shaped lace comprises round or oval portions associated with flat portions. The round or oval parts are, by their shapes, reinforced to hold the ankle and / or the base of the lacing more firmly for walking and running in the mountains. In other words, the round or oval shaped parts are positioned in the middle of the lace, to ensure the base of the lacing, and / or the free ends of the lace to ensure the firm support of the ankle. It is furthermore obvious that a round or oval shaped portion corresponds to a portion (or segment) of substantially circular or oval cross-section. The flat portions on this lace are intended to provide comfort on the toe, in providing a softer hold compared to round or oval parts, and is therefore between the middle of the lace and the ends of the lace. It is furthermore obvious that a flat portion corresponds to a portion (or segment) of flattened cross-section (with a thickness less than the width). Thus, advantageously, the lace successively comprises, from one end to the other, a first end portion of round or oval shape, a first flat intermediate portion, a central portion of round or oval, a second flat intermediate portion and a second end portion of round or oval shape; the two end portions being those which will be tied together and which make it possible to maintain the ankle more firmly, the central part being that which is situated at the base of the lacing, and the intermediate parts (situated between the respective end parts) and the central portion) being located on the foot 5 in a lacing situation. The second embodiment of the invention thus more particularly relates to comfort and optimal support of the foot, considering a study which showed that it was necessary to take into account the thickness, the diameter, the height and the width lace to have the closest features to provide optimal support, adjustable, pleasant and that it responds to the increase in the pressure of a foot to always maintain, especially in sports. With a lace according to the second embodiment and therefore with several shapes, the round or oval shaped parts (reinforced parts) allow to have a firm hold or tightening at the bottom of the lacing (thanks to the central part) and the ankle level to close the lacing by a loop (thanks to the end parts), while the flat intermediate parts are positioned on the kick and guarantee a low compression. According to one feature, the manufacture of this multiform lace 20 requires a mold, otherwise it is made by molding a silicone material. In general, thanks to the use of silicone, variations of the silicone lace are dictated by the pressure of the foot. Thus, as the pressure of the foot increases, the silicone lace is stretched as needed by the foot, and conversely, as the pressure of the foot decreases, the silicone lace will shrink at the rate of this decrease. According to one feature, for the multiform lace, the connections between the oval or round parts are conical with the flat parts. In use during the first lacing, the foot is initially inserted in the shoe without said lace, said shoe comprising lacing means such as holes, eyelets, hook, passing fabric. The lace is passed through said lacing means of the shoe by accompanying the lace and taking into account the sensitivity of the foot in order to match the lace with the morphology of the foot. With a lace according to the invention, it is therefore not necessary to pull on the lace as with a classic lace fabric, but it is advisable to accompany the lace as and lacing. For example, for use in trail, during the first lacing, it is recommended to tighten a little more the central part (round or oval part) to prevent the toes touch the tip of the shoe, then to place 10 flat intermediate parts without tension on the kick, and finally, to finish the lacing, to tighten the end parts (round or oval parts) before making a loop. It is then possible to cut the ends of the lace if the latter is too long. In use, it is no longer necessary to retouch the adjustment of the lace, and it suffices only to undo the buckle to remove the shoes. Still for example, for use in triathlon or running, during the first lacing, it is recommended to place the central part of the lace without applying tension, then to place the flat intermediate parts also without tension on the kick, and finally, to finish the lacing, to tighten more or less the end portions, pulling a little to recover from the game, before making a loop or making blocking knots at each end. Advantageously, the ends of the lace are bevelled at 30 ° to facilitate their passage through the holes, eyelet of the shoe. The ends can be cut too long to adjust the lacing and to avoid having too long laces which can cause a fall. When lacing, we install course the lace more firmly or more flexibly at its convenience. Once the adjustment of the lace installed on the shoe according to the morphology of the foot, it will not move. The silicone also allows the knot and the buckle not to be undone. This 30 makes it possible not to fall because of a defeated lace. This advantage is particularly relevant for people with reduced mobility, children and the elderly. The silicone lace can be cut once installed on the shoe to avoid having lace and loops too long. As observed, the special feature of the silicone lace is self-locking. As a result, even with part of the broken lace, the foot will still be maintained. The silicone lace offers the possibility of making a lacing with tension, strongly maintained or pleasantly maintained, but never tight. Whatever the tension, the lace will always offer optimal comfort and pleasant that will not move. Thanks to the silicone material used, the lace is resistant to ultraviolet and thermal shock. In addition, even when the lace is wet, the knot can still undo without problem, and finally such a lace will not freeze and still offer its utility. Other features and advantages of the invention will emerge more clearly on reading the detailed description which follows, made with reference to the appended figures among which: FIG. 1 represents, schematically, a silicone lace according to the first embodiment of FIG. embodiment of the invention, that is to say of the same shape over its entire length, whether flat, oval or round, and with its bevelled ends at 30 ° to facilitate the passage in the holes of the shoe ; - Figure 2 shows schematically the silicone lace of Figure 1, once installed on a shoe; 3 schematically represents a lace seen from the side according to the second embodiment of the invention, that is to say with the various rounded or oval shaped parts and the flat parts, the various parts being interconnected by conical connectors and the lace having beveled ends at 300; FIG. 4 schematically represents the lace of FIG. 3, once installed on a shoe, with the different parts of distinct shapes to adjust the different voltages, of which a central part to offer a tension more firmly maintained at the base of the shoe; lacing, two intermediate portions to achieve a pleasantly maintained tension at the kick, and two end portions to provide tension more firmly maintained at the ankle with the holes of the boot; - Figure 5 shows schematically the lace of Figure 3, once installed on a shoe, with the absence of the two end portions, and the presence of the central portion to provide a more firmly maintained tension at the base of the lacing, and the two intermediate portions to obtain a pleasantly maintained tension at the ankle with the holes of the shoe; - Figure 6 is a schematic perspective view of a shoe equipped with a lace according to the first embodiment of the invention; FIG. 7 is a schematic perspective view of the lace of FIG. 6; - Figure 8 is a schematic view of a cross section of the lace of Figures 6 and 7; FIG. 9 is a schematic perspective view of a shoe equipped with a lace according to the second embodiment of the invention; - Figure 10 is a schematic perspective view of the lace of Figure 9; - Figure 11 is a schematic view of a cross section of the lace of Figures 9 and 10, according to a cutting plane transversely cutting the lace in an end portion; - Figure 12 is a schematic view of a cross section of the lace of Figures 9 and 10, in a cutting plane transversely cutting the lace in an intermediate portion; and - Figure 13 is a schematic view of a cross section of the lace of Figures 9 and 10, in a cutting plane transversely cutting the lace in the central portion.
    [0006] With reference to FIGS. 2 and 6, a shoe C is equipped with a lace 1 according to a first embodiment, called the first lace 1, this first lace 1 consisting of a silicone band illustrated alone in FIGS. 7. This elongated elastic band is made entirely of silicone, and has a constant flat cross section over the entire length.
    [0007] By way of example, with reference to FIG. 8, the cross section of the first lace 1 is substantially rectangular. This first lace 1 can be obtained by injection of silicone material, or even by molding. Optionally, the ends 10 of the first lace 1 are bevelled at 30 °, to facilitate the passage through lacing holes 10 provided on the shoe C. With reference to Figures 4 and 9, a shoe C is equipped with a lace 2 according to a second embodiment of the invention, called second lace 2, this second lace 2 consisting of a silicone band shown alone in Figures 3 and 10.
    [0008] This elongated elastic band is made entirely of silicone, and has at least five successive elongate portions (or segments) comprising: a central said portion 20; two so-called intermediate parts 21 which surround the central part 20, in other words extending on either side (to the right and to the left) of the central part 20; and two so-called end portions 22 which extend the intermediate portions 21 on either side of the central portion 20. Thus, the second lace 2 presents successively, starting from one end to the other, a first end portion 22, followed by a first intermediate portion 21, followed by the central portion 20, followed by a second intermediate portion 21, followed by a second end portion 22. This second lace 2 can be obtained by molding of silicone material. The central portion 20 is a round or oval shaped portion and, as such, has a constant cross section (visible in FIG. 13) throughout its length, this cross section being substantially circular or oval. In the example illustrated in Figure 13, the central portion 20 is oval in shape with an oval cross section. The two intermediate portions 21 are flat portions and, as such, each intermediate portion 21 has a flat cross section (visible in Figure 12) constant along its length. In the example illustrated in Figure 12, each intermediate portion 21 is of rectangular cross section. The two end portions 22 are round or oval shaped portions and, as such, each end portion 22 has a constant cross section (visible in FIG. 11) throughout its length, this cross section being substantially circular. or oval. In the example illustrated in Figure 11, each end portion 22 is round in shape with a circular cross section. As can be seen in FIG. 3, each end portion 22 may be extended by a bevelled end at 30 ° to facilitate the passage through lacing holes provided on shoe C. Alternatively, and as shown in FIG. 10 each end portion 22 may be extended by a cylindrical section termination 23; a frustoconical portion 24 extending between the end portion 22 and the corresponding termination 23 to provide a regular diameter reduction. The end 23 also has the purpose of facilitating the passage through lacing holes provided on shoe C. Conical connectors 25 are also provided between intermediate portions 21 and, on one side, central portion 20 and on the other hand, the corresponding end portion 22, thereby reinforcing the interfacing areas between the intermediate portions 21 and the adjacent portions 20, 22. As seen in FIGS. 4 and 9, in situation on shoe C, once laced, central portion 20 is positioned at the beginning (or bottom) of the lacing zone, then the two intermediate portions 21 continue lacing at the the kick, and finally the end portions 22 complete the lacing at the top of the kick (at the ankle) and allow to achieve the closing loop of the second lace 2. Thus, each part 20, 21 , 22 has its own shape and thus its own elasticity to meet optimal comfort and hold, without compressing the foot, even after swelling, where the central portion 20 (the firmer) makes it possible to firmly tighten the second lace 2 at the toes, the intermediate portions 21 for a stable lacing and without tension at the level of the kick to provide a good venous return and good resistance, and the end portions 22 for a firm grip but not compressive at 10 n ankle of the ankle. As can be seen in FIG. 5, it is also possible to omit the aforementioned end portions 22 on the second lace 2, and thus to have only the parts 20, 21; so that the lacing at the ankle will be performed with the intermediate portions 21 flat, for a lacing more flexible than that made with the end portions 22 of round or oval shape.
