    Swimming fins with variable geometry, intended for training swimming and muscle toning in swimming pool, formed by a paddle, a shim and a counter fin, where the latter can adopt different positions with respect to the shim so that it allows exercise both muscles as their antagonists in the swimming phases. The counter fin is housed in a recess or guide located on the back and to plant the shim that allows it to slide, with closing of form, guaranteeing different positions between its two end ends of the race. In addition, the counter fin has a projection on its lower surface that is registered in an opening in the footplate of the shim so as to guarantee a closure in a way that allows the sliding of the contra flap, without the possibility of loss thereof, as well as guarantee the two extreme positions or end of stroke in the displacement of the counter-fin with respect to the shim. To define the extreme positions of the counter-wing in its stroke or stroke, the mechanism has transverse cylindrical pins that fix the counter-fin to the shim in the extreme positions of the counter-wing in its displacement or stroke.

    DESCRIPTION

    Swimming fins with variable geometry.

    Technical sector 5

    The invention falls within the sector of the design, development and manufacture of sports products, specifically in relation to the articles used in swimming pool training. It refers, more particularly, to swimming fins intended to strengthen antagonistic muscles in exercise programs and pool maintenance.

    Background of the invention

    The concept that is understood by fins covers different disciplines. On the one hand, they are 15 employees in diving, both professional and recreational. Secondly, its use in underwater fishing or apnea is also common. And finally, in swimming in a sports pool, as well as training or muscle toning. Despite being present in various activities, in all cases, the purpose of using fins is the same: the improvement in swimmer's propulsion. twenty

    As for the origin of the fins, it dates back to the 18th century, after the attempt to imitate the movements of the fish when moving underwater. However, it was not until the early nineteenth century when the first fins are patented.
     25
    From that moment, different fin models emerged, which were manufactured and marketed in mass. The main differences they presented were: the design of the fin, the material used, the manufacturing techniques used and the adaptation to the foot. Today, despite having spent many years since the first appearance of the fins as it is known, its variations continue to focus on the same aspects to differentiate 30 from each other.

    In fact, after a study of the utility models and patents that exist on the fins, none is found that has a complementary accessory and completely integrated in the fin, which implies versatility in the training of antagonistic muscles in the 35 phases Swimming By way of example, the following invention patents on fins are indicated:

    -ES0061551: "Fin improved for swimming"
     40
    -ES1075621: “Mini-fins”

    -ES1148308: “Flap transformable footwear”

    Nowadays, the fins are considered a very important accessory in aquatic practices, and for that reason there is a wide market that is dedicated to their sale.

    Explanation of the invention.

    The object of the present invention lies in a new way of conceiving swimming fins as regards their concept as an accessory for muscle training.

    When the fins are used in swimming, in training activities or muscle toning in the pool, different benefits for the swimmer are achieved:
    In the first place, the fins are an aid to increase the cardiovascular resistance of the swimmer, since it displaces more water than without them and, with this, a greater propulsion and therefore greater speed in swimming is achieved. With its use, the swimmer manages to develop less effort, which translates into less fatigue and more time to breathe. In this way, a greater recovery of the heart rate is achieved. 5

    Second, the fins allow the swimmer to be aware of the technique of kicking in each swimming style, both in the ascending and descending part in the whisk or leg cycle. In this way, the user is aware of the importance of the legs in this sport in each of the swimming styles. 10

    Finally, following the important role played by the fins on the legs, it is necessary to point out their help in strengthening the lower extremities. Although many swimmers focus their work on the upper body, it is also necessary to train the leg muscles. fifteen

    Today, the fins that exist in the market are not designed for the purpose of muscle strengthening by not contemplating the strengthening of antagonistic muscles, but instead focus on giving propulsion and greater displacement of the swimmer.
     twenty
    However, due to the pressure exerted by the water on the body, the work of the muscles in this environment is an even more effective activity than outside it, so swimming can be considered one of the most complete sports from the point of view of exercise and muscle toning.
     25
    Thus, the present invention supposes a new form of training for swimmers. This will be achieved by providing the new fin with a variable geometry, which will condition the resistance of the water that the swimmer has to overcome during the kicking cycle. To achieve this, there will be an auxiliary element, a counter fin, which will be integrated into the fin. The counter flap, arranged inside a recess that acts as a guide 30 and that is located in the lower part of the shoe and rear of the flap, can be slid over said recessed-guide, being able to adopt different positions. If the counter fin is hidden in said pocket, it does not exert any additional resistance to that corresponding to a conventional fin. On the contrary, if the counter fin slides outwards, the swimmer will exercise both the muscles that are put into play in conventional swimming with fins and their corresponding antagonistic muscles due to the existence of a counter fin deployed by the back of the fin.

    Descriptively, the swimming fins of variable geometry, which are proposed for the present invention, consist of the following parts: the paddle, the shoe and the contra fin. 40

    The first part, the shovel, protrudes from the front of the fin and is responsible for the thrust of the water during the cycle of kicking in swimming.

    The second part, the footwear, allows the swimmer's foot to adapt, comfortably and securely to the fin, avoiding the loss of it during the swim cycle.

    Finally, the third part is constituted by the contra fin, acting as an independent element of the blade and the shoe, which adopts different positions.
     fifty
    The versatility presented by this new product is due to a good integration between all its parts. On the one hand, the blade and the wedge are joined during the manufacturing process (usually by injection of polymeric materials) and, on the other hand, the counter fin that can be manufactured as a separate component and that is attached to the rest of the parts by means of a
    recessed as a guide that is practiced at the bottom of the shoe at the back of the fin. In this way, it is achieved that this component, the counter fin, does not occupy a fixed place in the fin, but can take several positions.

    To prevent the counter fin from being lost during the swim or swim kick cycle, a geometry has been devised between shims and against fin by closure so that it ensures that the counter fin cannot leave or leave the guide pocket before indicated. This is achieved with a through opening, located at the bottom or floor of the shoe, which reaches the guide recess in said part. On the other hand, the contra fin has a protrusion on its lower face, which is recorded in the aforementioned through opening. This allows the 10 against the flap to move longitudinally in the guide groove of the floor of the shoe, but with some stops or limit switches.

    As for the mounting of the contra fin in the guide pocket of the shoe, it can be achieved because the materials used in the manufacture are of polymeric type with high levels of plasticizer or elastomeric materials so that both sides have enough flexibility to insert a piece into the guide recess of the other.

    In order to ensure that the counter fin does not slide freely on the rail, the system has been provided with a system that allows to fix the positions of the counter fin on the shoe in a transverse manner. This has been achieved with pins that limit the sliding movement of the contra fin over the guide pocket. These pieces ensure that during the swim or swim kick cycle, the chosen position of the contra fin is always guaranteed. The position of the pins varies, at the user's discretion, thanks to slits, which allow the user to remove or put the pins. 25

    Preferred Embodiment of the Invention

    In view of the figures indicated, it is possible to observe how the swimming fin with variable geometry consists of three different parts: the paddle (1), the shoe (2) and the counter fin (3).
     fifty
    The first part, the blade (1), is the element that carries out the water thrust in the swim cycle and has the proper flexural stiffness for its function of water movement and thrust.

    The second part, the shoe (2), allows the swimmer to securely attach his foot to the fin and being made of a flexible material, allows a good adaptation to the user's foot.

    The third part, the contra fin (3), is an element manufactured independently of the rest of the fin and whose function is, to exercise the muscles of the leg and its corresponding antagonistic 5, presenting a capacity to exercise said muscles, much superior to that It is done with a conventional swimming fin.

    On the sides of the blade (1) there are two symmetrical channels (4) with respect to the axis of symmetry of the fin, of a thickness smaller than that of the blade (1), which ensure that it does not have excessive flexural rigidity, which would cause muscle damage in the user. In the same way, from the sides of the shoe (2), ribs (5) appear, which run around the blade (1). The combination of the two symmetrical channels (4) and the ribs (5) guarantees the correct flexibility and flexural rigidity of the paddle in the swimming or swimming kick cycle without causing muscle injuries to the user that would appear if said paddle it was too rigid to flex.

    At the rear of the shoe (2), a recessed housing (6) is opened, which serves as a guide for the contra fin (3). Likewise, the shoe (2), in its plantar area, has a through opening (7). Finally, on the sides of the shoe (2), two through holes (8) appear from side to side of the shoe (2) where the cylindrical fixing pins (11) will be introduced.

    For its part, the counter fin (3) has on its lower surface, a projection (9) that fits into the through opening (7) so that, with the contra fin (3) mounted, this projection (9) guarantees, by closing so that the counter fin (3) is not going to leave the guide pocket (6) as well as acts as a limiter in the travel stroke of the counter fin (3) in the guide pocket (6). In the assembly of the contra fin (3) in the shoe (2), the contra fin (3) slides housed in the recessed housing (6) while the projection (9) runs through the through opening (7), thus defining the extreme positions of the contra fin (3) and, avoiding the loss of the contra fin (3). 30

    To guarantee the positions of the contra fin (3) in the shoe (2), a transverse groove (10) is made on the lower surface of the contra fin (3) and on the shoulder (9), which coincides with the two axes of the through holes (8) of the shoe (2) in the extreme positions that the counter fin can occupy in its travel stroke. To fix the counter fin (3) 35 with respect to the shoe (2) in its extreme positions, there are two cylindrical pins (11) located in the transverse groove (10) and which can be moved laterally so that said pins ( 11) are introduced into the through holes (8) of the shoe (2).
