    Fins of variable geometry for training, formed by a conventional fin, preferably manufactured by injection in polymeric materials, to which different accessories are incorporated to allow a type of anaerobic training in the water. These accessories are a counter-wing, housed and concealed in the lower part of the swimmer's foot and which allows two operating positions per turn, folded and unfolded. The connection between fin and counter-fin, as well as the blocking of the rotation in the operating positions, is made by an axis and concentric and longitudinal grooved guides. In addition, the fin incorporates a self-closing strap that helps the counter-fin to resist the forces exerted by the weight of the water in its deployed position, acting as a tie-rod and that is fastened on the instep, as a sandal, when the counter-wing is folded.

    [0002] Variable geometry fins for training.
    [0003]
    [0004] Technical sector
    [0005]
    [0006] The invention referred to in this document falls into the field of design and manufacture of sporting goods. Specifically, it deals with the development of a new type of fin that allows a totally new training.
    [0007]
    [0008] Background of the invention
    [0009]
    [0010] Although diving fins date back to the 18th century, it is not until 1914 when the first patent related to the invention is registered. By this time, the fins were made of wood or tree leaves like the palm tree. The purpose of these inventions was to improve propulsion in the recreational diving swim and in the competition swim. This type of manufacturing was soon abandoned and the fins were patented as they are known today, manufactured in a single polymeric material by molding. Specifically, the first fins of this type were made of vulcanized rubber in 1940. From this moment, the progress in the designs was very large, since the use of fins was popularized and therefore the number of companies dedicated to the sector . The advances that have arisen are related to full-fitting fins, which arose in the manufacture of footwear in Italy in the 1960s, the use of lighter materials, or the incorporation of ribs of different material to the rest of the fin.
    [0011]
    [0012] At present, there are models of racing fins on the market made of advanced composite materials such as carbon fiber or glass fiber. As for the state of the art, it is worth mentioning, by way of example, the following invention patents:
    [0013]
    [0014] - ES 2026617: "Swim fin with the part of the fin and the part of the sole separable from each other"
    [0015]
    [0016] - ES 2072785: "Swimming fins"
    [0017]
    [0018] - ES 2233012: "Swimming fin and manufacturing procedure"
    [0019]
    [0020] However, none of the existing patents to date, incorporate the improvements and training possibilities that open with the model of the present invention, assuming a great advance and differentiation in the sector.
    [0021]
    [0022] Explanation of the invention.
    [0023]
    [0024] So far, the fins have been developed to help the swimmer propulsion in any water sport, whether it is surface diving, swimming, deep diving, etc. For this reason, all registered inventions have sought to obtain greater propulsion, reducing the weight of the fin and improving the system of flexion and displacement of water in the kick.
    [0025]
    [0026] The type of exercise performed with conventional fins, is an aerobic exercise, in which the athlete improves his background and cardio-vascular attributes. However, in all athletes of any discipline and, with greater need in elite athletes, it is necessary to include a weekly work of anaerobic exercises, which improve the muscle and strength of the athlete, aspect directly related to the health and performance of it.
    [0027]
    [0028] To date, this type of training is done in a gym with weight exercises, or with functional workouts that use the athlete's own body weight for training. What the present invention raises is to combine traditional aerobic exercises with anaerobic exercises without leaving the water, using the fins developed for the present application. In addition, such training allows to work antagonistic muscles normally used in swimming, thus allowing a healthier and more balanced development of the muscles.
    [0029]
    [0030] On a technical level, the present invention will allow training by means of variable geometry fins, depending on the needs of the swimmer. These fins have the following characteristics:
    [0031]
    [0032] First, the swimmer can use them as conventional fins, since their basic formal geometry is similar to the fins present in the market. In addition, they are manufactured in materials and manufacturing processes similar to those existing in the market through current.
    [0033]
    [0034] However, the basic geometry incorporates a counter-fin at the bottom of the shoe, where the swimmer's foot is located. Said counter-fin, which is hidden in a hole located in a plane parallel to the bottom of the swimmer's foot and below it, is smaller than the conventional fin blade and is attached to the rest of the fin by a cylindrical axis, which allows the rotation of the counter-fin by 180 °. This turn allows the counter-fin to have two positions. The folding position, in which the counter-fin is hidden under the swimmer's foot; and the deployed position, in which the counter-fin is exposed and protrudes through the heel. These two positions are locked during use, to ensure that its operation is efficient and safe for the swimmer. Said blocking is carried out by two mechanisms arranged for it. On the one hand, the counter-fin incorporates circular and concentric grooved guides to the joint axis, which house pivots of the fin's own wedge material, obtained in the manufacturing process. For its part, the counter-fin's use position, in either of its two positions, is obtained when the aforementioned pivots reach their extreme positions. On the other hand, two longitudinal grooved guides are arranged, parallel to the swimmer's foot, and located in the area of the shoe hole; while the counter fin, has two ribs in the same direction described. When the counter-fin reaches one of its use positions, the ribs are housed in the guides, causing the counter-fin to block. To release the system from the blockage, it is necessary to make a small turn in the opposite direction, which allows the ribs to free themselves from the guides and return to the desired position.
    [0035]
    [0036] Finally, it is necessary to note that the bending forces to which the counter fin is subjected during the swimmer's kick, the result of the weight of the displaced water, are too high for only the described axis to resist. To give solution to this aspect, the counter fin has on its sides a groove where a self-closing belt or tape is fixed. This strap also has two possible positions of use. First of all and, if the counter-flap is folded, the strap is fastened over the swimmer's instep, as a sandal. Secondly and, if the counter-flap is deployed, the strap is fastened by the front part of the swimmer's ankle. In this position, the belt acts as a strap that helps the counter-fin resist the forces and bending pairs that would appear in the swimming kick.
    [0037] Brief description of the drawings
    [0038] To complement the description that is being made and, in order to help a better understanding of the characteristics of the invention, a set of drawings is attached as an integral part of said description where, for illustrative and non-limiting purposes, represented the following:
    [0039] Figure 1. Shows a top perspective view of the fin with the counter-flap folded. Figure 2. Shows a bottom perspective view of the fin with the counter-flap deployed. Figure 3. Shows a profile view in which the fin can be seen with the counter-flap deployed.
    [0040] Figure 4. It shows a detail of the system of rotation and position lock of the counter-fin in two views (back and bottom floor).
    [0041] Preferred Embodiment of the Invention
    [0042] In view of the aforementioned figures, it can be seen how the device is constituted by two main parts: fin and counter-fingertips that can be coupled together. The fin is formed by an ergonomic body, known as a shoe (1), which houses the user's foot, from which two main ribs (2) are derived, one on each side of the shoe (1), and which follow a section variable, from greater to lesser thickness from its beginning, in the area of the foot, until its end, at the end of the fin. This part of the fin also has an area known as a shovel (3), of a material with greater flexibility than the ribs (2), which is placed between them; having as function the displacement of the water during the swimming kick. The adjustment of the fin to the foot is bare heel, and incorporates an adjustment strap (4), anchored to two buckles (5), located on the sides of the shoe (1).
    [0043] Finally, the fin incorporates two secondary ribs (6) longitudinally into the central area of the blade, which provide resistance to flexion to the blade (3). In addition, and as added in the present invention, the ribs (2) have a groove (7) through which the self-closing belt (8) passes, which will be described below.
    [0044] The union between all the elements that make up the fin is given by the manufacturing process, and it is the polymeric material itself melted at high temperatures that is responsible for joining and sealing all the pieces together.
    [0045] In Figures 2 and 3, it can be seen that the lower area of the shoe (1), present in the fin, has a recess (9) where the counter-fin is housed. Said counter-fin may be in the folded position, under the swimmer's foot, or in the deployed position, protruding backwards from the swimmer's heel.
    [0046] The rotating joint between the fin and the counter-fin is performed by a rotation axis (10), which in turn is reinforced by a system that limits the rotation to 180 ° and blocks the extreme positions at the operating points, just as It is explained in Figure 4.
    [0047] In addition, in figures 1 and 3, the self-closing belt (8) is detailed, in charge, depending on the position of the counter-flap, of fastening and holding the counter-fin in its position. In the event that the counter-flap is folded, the strap (3) is fastened on the instep, leaving the contra-fin housed under the foot and in disuse. In the event that the counter-fin (2) is deployed, the strap (8) is buckled in the front part of the ankle and helps the counter-fin to withstand the bending forces generated by the weight of the water at the end of the counter-fin in the swimming kick.
    [0048] Once the nature of the invention has been sufficiently described, as well as a preferred embodiment, it is stated for the appropriate purposes that the materials, shape, size and arrangement of the described elements may be modified, provided that this does not imply an alteration. of the essential features of the invention that are claimed below.
