    DESCRIPTION 5 10 15 20 25 30 35



       DYNAMIC AND AEROBIC DEVICE FOR STRETCHING AND FLEXIBILIZATION OF THE FEET.

    SECTOR OF THE TECHNIQUE.

          Instruments for the preparation and training of classical ballet.


    STATE OF THE TECHNIQUE.

              Stretching and foot flexion devices that currently exist are inadequate to solve important needs for students and dancers of classical ballet or other athletes who need to stretch and flex their feet. Although the Device for stretching and increasing the flexibility of the foot, protected in its day with the U 9700652 model, was at the time a great novelty in the conformation and reinforcement of the feet of the ballet dancers, the practice During the last 17 years, it has shown that it has deficiencies that significantly hinder the result of the molding of the foot, the aerobic function that is advisable to accompany its use, as well as other functional possibilities that the practice of classical ballet, increasingly demanding, or foot stretching exercises, demand today.


    EXPLANATION OF THE INVENTION

              TECHNICAL PROBLEM

    There are currently several devices to facilitate stretching 5 10 15 20 25 30 35 and ensure the flexibility of the feet of the classical ballet dancer. The first and oldest is the “Device for stretching and increasing the flexibility of the foot” protected by David Campos with the U 9700652 model. Its long and one-piece handle has proven very useful for driving safely (without force the arm or risk of breakage) the foot with the hand to certain positions; but at the same time it has the disadvantages of hindering or preventing the realization of certain movements of great importance and workouts standing or in arabesque with the device placed. Second, the device itself has an excess of weight that is inappropriate for certain exercises, while it is insufficient for others, and, especially, to achieve an adequate degree of aerobicity to ensure an optimal torrent of blood circulation and, consequently, of oxygenation of the musculature of the foot. Third, the upper frontal protuberance, an element of the greatest importance in shaping the foot, was discovered longitudinally excessively elongated while being too flat in its highest part. This conformation has proved unsatisfactory enough in the performance of its stretching and flexibilization function, delaying or hindering the desired final result, as well as in the placement of the device by its lower part or sock. And, fourth, the tubular piece of rubber that has been used to fasten the foot to the mold of the old device had several drawbacks: it is difficult to remove and put on; exerts too much pressure on the upper part of the foot and on the heel, where it is not necessary, and, on the other hand, the pressure on the lower part of the foot and the area of the toes is insufficient. Neither the form and its termination are suitable for performing foot exercises with the device placed on the floor, since, when it has an irregular finish, its use in contact with the ground can affect the stretching forces that the bra Tubular exercises on the foot.
             As for the second device, which has been the subject of a patent application US 14 / 277,136 and PCT WO 2014186502, which we are going to oppose at the time of due process to understand that it is novel, does not introduce any innovation or improvement technique in the functionality of stretching and flexibilization of the foot with respect to the David Campos device indicated above. This device only introduces the possibility of separating the handle from the part of the device (somewhat foreign to the device's own stretching function) by means of a simple external thread (an obvious solution for any expert in a simple external thread (an obvious solution for any expert in the single outer thread (an obvious solution for any expert in the single outer thread (an obvious solution for any expert in the single outer thread) (an obvious solution for any expert in the single outer thread (a solution obvious to any expert in a simple outer thread (an obvious solution to any expert in the
                 Other types of subsequent devices that we have seen in the state of the art are far from finding a solution to the technical problems that the invention solves that we intend to protect with this application.


    PROPOSED SOLUTION.
     25
                         It is important to note that this description has, together with the accompanying drawings, an exemplary, non-exhaustive nature, based on one of the best ways to specify it, without thereby attempting to limit other equivalent possibilities of this invention. Other non-substantial modifications will be apparent to a person skilled in the art in view of what is explained here.
               For the solution of the aforementioned problems, after long years of studies with different variations and prototypes, a new device was designed that, on the basis of a low piece or stretch shoe (2) of approximately 43 cm in length, and a high piece or handle (1) of approximately 33 cm in length, is defined by the combination of the following technical solutions.
              First, the new device is composed of two parts joined by a coupling mechanism by internal screwing and with external channel, expressly defined to respond to the functional requirements of the device. This internal thread system serves to securely connect the two devices. This internal thread system serves to securely connect the two devices. This internal thread system serves to securely connect the two devices. This internal thread system serves to securely connect the two devices. This internal thread system serves to securely connect the two devices. This internal thread system serves to securely connect the two devices. This internal thread system serves to securely connect the two devices. This internal thread system serves to securely join the two
             Second, in the redefinition of the insole (8), part of the foot strap in contact with the foot, the length of the central protuberance (9) of the 14 cm of the old device is reduced to 7.5 cm in the current one, to the current Once the slope on both sides of the protuberance is softened from an approximate width from the base of 4 cm in the old device to a width of approximately 5 cm in the current one, entering this protuberance through the center to a flat area of approximately about 9 cm in length.
             Third, according to the resistance capacity of the manufacturing material, the volume is reduced to the maximum and with it the weight of the stretch shoe (2) to provide it with the greatest possible lightness. At the same time a weight (11) of between 700 and 1000 gr is designed. (Other weights, smaller or greater, are also possible for special requirements and their use is evident to a person skilled in the art) that can be joined or separated from the sole (12) of the stretch shoe (2).
             Fourth, a belt of approximately 44 cm in length and 3 cm in width is designed (other widths and lengths are also possible, as well as introducing a widening in the leg contact part for greater comfort, and evident to an expert in the matter) used to hold the leg to the complete device by holding it above the knee (3), just above the upper end of the handle (4); or only to the stretch shoe (2) holding it at the height of the mid calf (5), just by the concave channel (18) (other forms of anchorage - wrinkles, magnetization, Velcro® etc.) on this piece or the upper end of the Stretches are also possible and obvious to a person skilled in the art) who

            Fifth, a semicketin-bra-elastic is developed (Figs. 12 to 16) that responds specifically to the anatomical needs of the foot applied to the device. It has a trapezoidal plant (22) longitudinally with a long open side (23) of approximately 13 cm and the opposite side short, 8 cm. approximately, where the closed termination (24) is located, both separated by an approximate height of 20 cm. These approximate measures, while maintaining their basic design principles, could vary to conform to a new format of streches or feet of special dimensions. This basic trapezoidal shape (22) (in the sense that it would continue to be maintained even if the parallel sides or the lateral faces present some bulging or rounding at the angles), whether contemplated in plan and in profile, obeys the need to distribute the pressure in a way it balances on the relevant elements of the foot according to its natural form, so that the perimeter of the foot strap is adjusted, depending on the interior volume and the force required on each area of the foot in the corresponding part of the insole (8) of the Stretch (2), to the functional requirements of stretching of the template (8) of the stretch (2), to the functional requirements of stretching of the template (8) of the stretch (2), to the functional requirements of stretching of the template (8) of the stretch shoe (2), to the functional requirements of stretching of the template (8) of the stretch (2), to the functional requirements of stretching of the template (8) d the stretch (2), the functional requirements of stretching of the template (8) of the stretch (2), the functional requirements of stretching of the template (8) of the stretch (2), the functional requirements of stretching of the footbed template (8), to the functional requirements of stretching of the footbed (8) of the footwear (2), to the functional requirements of stretching of the footbed (8) of the footwear (2), to the functional requirements stretching
              Two other characteristics of the semi-clamp-elastic-brace that contribute to defining the degree of pressure of the foot on the stretch shoe (2), are the degree of density of the silicone (or equivalent material) and the possibility of fitting a sock into another your application. First the increase or decrease of the force can be achieved by increasing or decreasing the density of the silicone at the time of manufacture on a scale between 20 or 70 shoes. And, second, by manufacturing the semi-elastic-bra-elastic with different densities (between 20 or 70 shoes) and in such a way that everyone can fit in another sock, possibility that defines the semi-elastic-bra-elastic that we propose to protect, you can get 35 increase or decrease the force of action on the foot by adding or subtracting semi-elastic bracelets in its application.

    It should also be noted that the upper edge (28) and flat on the open side 5 10 15 20 25 30 35 (23) of the upper end of the semi-clamp-elastic-fastener is finished with a rim (34) of approximately 4 mm. of thicknesses that protrude around 1.5 mm. outwards (other measures are possible and obvious to a person skilled in the art), with the purpose of facilitating the winding and unwinding of the semi-clamp-fastened-elastic on the foot applied to the stretch, while reinforcing the upper termination and its capacity of exerting force on the foot.
             Finally, it should be noted that, in order to apply it to the stretch shoe, the semi-clamp-bra-elastic must be wound on itself from its open side (23) until shortly before the closed termination (24), for, once the foot is introduced Applied on the stretch in the resulting cavity, unwind it while covering the upper part of the foot with the upper part of the semi-elastic-fastener-elastic finished with the trim (34) and the sole (12) the stretch with its lower part finished with the concave curve (29).

    ADVANTAGES.
      The proposed dynamic and aerobic foot stretching and flexibilization device has the following advantages:
    1. Leave your hands free by allowing the device to be attached to the dancer's foot without the need to hold it or orient it with the handle.
    2. When the leg is attached to the entire device (above the knee or upper end of the control), the leg is prepared for rigid leg exercises (Fig. 3).
    3. When the leg is attached only to the device (through the middle calf -5- and through the channel -6- of the connecting piece), the knee play of the leg is completely free for different exercises (Fig . 4).
    4. This allows the implementation with the applied device of exercises accompanied or oriented with the arm by the handle (1), as exercises with rigid leg without accompaniment, as exercises with free knee.
    5. These greater possibilities of exercise that favor the blood circulation of the dancer and aerobic, especially in the muscles of the foot, leg and hip joint.
    6. This beneficial effect increases thanks to the possibility of performing light weight exercises without weight (11) and weight exercises (11) with the stretch shoe. The aerobic that is achieved with these two types of exercises, especially when using the weight (11), favors the exercises, especially when the weight is used (11), favors the exercises, especially when the weight (11) is used, favors the
    7. The concave channel (18) that allows the fastening piece fixes the fastening tape in the optimal position for fixing the device and performing without discomfort of exercises. This without damaging or disturbing the user during the exercises.
    8. The longitudinal shortening and lateral smoothing of the protuberance (9) located under the sole of the dancer facilitates the placement of the sock of the stretch shoe, improves the adaptation of this part of the foot to the device both flat and lateralized, increases the effect of the action of the device on the instep-bridge area by having a shorter length, while avoiding slipping or poor placement, which translates, in addition to greater comfort and ease of use, in a result of flexibilization and stretching more efficient, precisely in the most delicate and important parts of the foot for the dancer.
    9. The semi-elastic-bra-elastic adapted to the anatomy of the foot applied to the device allows a balanced pressure distribution and focused on the most relevant parts while relieving excessive pressure on other delicate parts such as the instep, the heel or the Achilles tendon.
    10. The closed and rounded termination at its angles and edges (26) adjusted to the shape of the closed termination (24) of the stretch shoe allows for a perfect fastening of the sock to the stretch shoe, performing exercises with the stretch shoe on and resting on the floor, and the unaltered execution of elastic forces on the foot.
    11. The different densities with which the semicalcetin-fastener-elastic is manufactured, as well as the possibility of fitting a semicalcetin-fastener-elastic within another, allow them to be adjusted to different foot sizes and to different force requirements.
    12. The edging (34) that protrudes rounded over the upper edge of the open side of the semi-clamp-bra-elastic, facilitates the screwing of the semi-clamp-bra-elastic while reinforcing the action of this part of the upper face on the foot .

    DESCRIPTION OF AN EMBODIMENT

                       The manufacturing process consists of the following steps: Selection of the most appropriate wood and materials for the function that must be developed in the device.
            The wood is positioned on the pantograph copier to sculpt the exact upper shape. Then piece by piece is installed on a lathe to give the rounded finish of the back where the metal connecting piece will then be introduced. Once the shape has been given, the wood is polished, taking care not to modify the functionally relevant form in the least.
           The internal threaded coupling mechanism with external channel is composed of three parts. It starts from a metal cylinder in which the concave channel is excavated on the outside. Likewise, a cylindrical cavity is drilled in its center, at the center of which is placed another smaller cylinder that carries the male thread (Fig. 10). On the other hand, another circular flat base piece of whose center is prepared (Fig. 10). On the other hand, another circular flat base piece of whose center is prepared (Fig. 10). On the other hand, another circular flat base piece of whose center is prepared
           Then we proceed to paint the pieces of wood, finishing with a layer of colorless varnish that gives greater resistance to bumps and rubs.
           Once the pieces are painted, the metal joining elements are assembled: the flat disc from which the cylinder comes out with the inner female thread at the lower end of the handle and the concave cylinder with the outer male thread in the lower cavity at the top of the Stretch
           The weight is formed by adding metal balls to a flat bag, which presents on one of its faces a connecting element that is complemented with the other element that is placed on the opposite side to the pressure of the lower part (finger height ) Stretch.
           Once the mold is manufactured, the semi-elastic-fastener-elastic is manufactured by injecting the sanitary silicone for direct contact with the skin in the corresponding mold for the desired strength and density and the removal of the mold after cooling.
