Sport projectile

The invention relates to sports equipment with an unstable surface, designed to improve and maintain physical fitness. The invention can be used when practicing fitness, for performing physical exercises to develop coordination, strength and endurance. Sports equipment can also be used in any areas of activity that are aimed at increasing, improving and maintaining muscle tone, including physical rehabilitation, fitness exercises, development and development of motor skills, in particular, increasing the ability to maintain balance and improve posture.

In the prior art, equipment for training on an unstable surface is known: fitballs, hemispheres and other unstable devices. For the first time, exercises on an unstable surface began to be applied in clinical conditions, in physical therapy. Scientific studies have found that exercises on an unstable surface help restore sensory function for the reason that the central nervous system receives more information to send the right motor impulses. However, the known projectiles do not fully meet the requirements of efficiency and safety.

From CN202173736 (U) 2012-03-28 known elastic fitball, equipped with handles in the form of ears, foot rings. The body of the body is made in the form of a ball. A disadvantage of the known solution is the form of the performance of a sports projectile in the form of a ball, which limits the ability to perform exercises, for example, standing with feet on a fitball, because of the injury risk. Fitball is hollow inside, which reduces the effectiveness of training, since the instability of the projectile is provided solely by its shape.

In part, these problems are resolved in RU 2581813 (C2, published 04/20/2016), chosen by the applicant as the closest analogue. The device for improving the physical shape includes a specially selected shell filled with filler. The shell can be filled or emptied during workouts (directly on site). The shell does not have tapes or handles on the outer surface. The size of the shell is chosen so that it matches the width of the user's shoulders. The shape of the shell contour, at least in the front view, is a lemniscate with a longitudinal axis that serves as an axis of symmetry, and with two separate sections of maximum width at a right angle to the longitudinal axis (patent RU 2581813 C2, published April 20, 2016).

To the disadvantage of this device should be attributed to its form, since with incomplete loading, the filler may accumulate in one of the two extreme sections, which leads to uneven loading. The absence of handles limits the execution of a number of exercises, in particular, various manipulations with the device in the air. These shortcomings make the well-known solution less effective for training because it limits the ability to perform the exercises, especially during the period of medical and physical rehabilitation.

The present invention is directed to solving the problem of creating a sports projectile, the instability of which is provided by both the form and the filler, which uses liquid or solid bodies that can move easily inside the projectile, while being effective and traumatic for training different groups of users. When solving this problem, the technical result is achieved, which consists in creating a sports projectile with an unstable surface, in which you can simultaneously change the weight of the projectile and adjust its elasticity, which in turn allows you to give aerobic, anaerobic and static load on the user's muscles and, consequently, increase efficiency workouts.

In addition, the claimed invention allows to expand the Arsenal of technical means for this purpose.

This technical result is achieved by the construction of a sports projectile.

Sports equipment in the first embodiment is a flexible shell with an internal volume, made in the form of a sealed chamber with a valve, the internal volume of the chamber is designed to be filled with filler and / or air. Sealed camera is located inside the case with handles. After filling the internal volume of the chamber with a filler and / or air, the shape of the sports projectile is essentially a rectangular parallelepiped with rounded corners. The side surfaces of the projectile form a closed surface. The height of the side surface is not more than half the length of the projectile. The supporting part of the projectile and the part with which the user interacts are made identical and convex to the outside. The cross-section of a sports projectile in working condition is an ellipse. The mentioned parts of the sports equipment are unstable surfaces.

The case is made of durable non-slip fabric.

The tight chamber is made of polymeric material.

The filler is a material that provides easy movement inside the chamber.

On the side of the case of sports equipment are handles.

On the side of the cover of the sports projectile, there is a hole for access to the valve of the sealed chamber and a valve for removing the chamber from the cover.

The second option is the implementation of the projectile without a cover.

Handles are performed together with an elastic chamber.

The implementation of a sealed chamber flexible, filled with filler and / or air under pressure, together with its shape allows you to make the surface of the projectile unstable. Under the unstable surface should be understood unstable, variable nature of the surface. The instability of the surface in the dynamics (when using a projectile) provides a filler, in static - air. The filler allows you to change the weight of the projectile (you can reduce or increase the amount of filler) and adjust its elasticity by changing the air pressure through the valve in a sealed chamber. Handles allow you to securely hold a sports equipment and perform various manipulations in the air. The proposed sports projectile makes it possible to distribute the physical load on the various muscle groups of the user, to significantly expand the arsenal of exercises performed, which increases the effectiveness of training. The shape of the projectile according to the results of the tests showed the greatest efficiency compared with other projectiles with an unstable surface. Also noted is the convenience of using the projectile and the safety of the exercises, due to the supporting surface, the slight height of the projectile and the presence of handles.

FIG. 7 - photo of the finished product in the first embodiment.

Sports equipment is a flexible shell with an internal volume, the shape of which is based on a rectangular parallelepiped with rounded corners. The cross section of a sports projectile in working condition after filling it with filler and air is an ellipse, with the proviso that the shape is similar to an ellipse, but the shape of the finished product may not be an ellipse according to the definition of this concept.

Sports equipment in the first embodiment (Fig.1-3) consists of a cover 1 with handles 2, inside of which is an airtight chamber 3, which is filled with filler and air. The cover 1 is made of durable non-slip fabric. Handles 2 are placed on the same axis from opposite sides of the side surface 4 of the cover 1. Handles 2 of the cover are made of textile slings, braid or other durable material. On the other axis, also from opposite sides, on the side surface 4, there is an opening 5 for free access to the valve 6 of the chamber 3 and the valve 7. The said axes are perpendicular to each other and intersect in the center of a sports projectile, made in the form of a pillow. Hole 5 can also be fitted with a valve. The valve 7 is closed with a zipper, velcro, buttons or other means of connection.

Sports equipment has the same support surfaces 8 and 9, made convex outward. Conventionally, the support surface 8, 9 can be called the upper and lower. When using a sports projectile, the lower surface will be that which it will lie on the floor or face to the floor, and the upper surface that the user will rest with by hand, foot or other part of the body.

The length (L) of the support surface 8 (9) is preferably equal to the width (B) of the projectile. For the greatest effect, the length (L) of the projectile is chosen according to the width of the user's shoulders; otherwise, the exercises with the projectile will not be effective. It is possible to carry out projectiles of different sizes, intended for men, women, children

The side surfaces 4 of the projectile from four sides form a closed surface. To achieve a technical result, it is also important that the height of the side surface (h) be no more than half the length of the support surface L (see Fig. 4). The side surfaces 4, forming a closed surface around the perimeter, prevents the projectile from “blowing” into the ball. It should be obvious to a specialist that a slight difference in performance when measuring the supporting and lateral surfaces in actual use is not fundamental, production errors are permissible.

Chamber 3 is made of flexible material, preferably polymeric, for example, PVC plastisol and is an unstable surface.

The implementation of sports equipment with a cover has advantages. Thus, the production of a camera without handles is simplified, while the handles are sewn to the cover and, if necessary, the cover is easily replaced. In addition, the case protects the camera from accidental punctures. The case can be made of durable fabric of any color, with individual initials, corporate logo. However, the second version of the sports projectile, characterized by the absence of a cover, can also be implemented (Fig.4.5). In this case, the sealed chamber 3 is made integral with the handles 2. The sports equipment also includes a valve 6 for filling the chamber with filler.

The simplest available filler is water. Other substances and materials can be used as fillers, for example, sand, liquid gels, hydrohelium balls, polymer granules and other liquid or solid substances that can easily move inside the chamber.

It is possible to use a projectile filled only with air (without filler), but the effectiveness of training with such a projectile will be much lower for the reasons described above.

To enter the sports projectile in operation, open the valve 6 of the chamber 3 and fill it with a filler, such as water, through the hole, and pump it with air. After which the valve 6 tightly closed. Sports equipment ready for use.

The volume of filling of the chamber with filler depends on the physical fitness of the user. Experimentally, it was determined that for maximum effect from training with the proposed sports equipment the camera should not be filled with more than 81% of the total volume and at least 9%. If the amount of filler in the shell is less or more than the specified values, the effectiveness of the exercise is reduced.

The proposed sports equipment can be used to perform the exercises standing, sitting or lying on it. In addition, using the handles 2, the user has the ability to manipulate the sports projectile in the air. During the use of the proposed sports projectile (the user can hold it in front of or above himself, or, relying on such a sports projectile), the filler is moved inside the projectile, and to balance it, as well as perform an exercise with it, the user needs to make additional efforts that turn leads to additional calories burned compared to projectiles without a changeable center of gravity (dumbbells, weights, barbells, cores, etc.). When using the product in the form of an unstable surface (when the user leans on him with his hands, feet, or any other parts of the body) there is a need to constantly maintain balance, which in turn leads to the fact that during exercise the calories are burned more than usual. The combination, as well as the rapid transition between the methods of employment with the projectile described above, are also distinctive features of the product. In the process, almost all the muscles of the body are actively involved.

Thanks to the filler and the air in the chamber 3, the sports equipment can be used as a burden with a variable center of gravity when performing air manipulations.

The weight of the product is regulated by adding or reducing the amount of filler in the chamber, the pressure inside the chamber can also be changed depending on the purpose of the workout.

Without a filler, the weight of a sports apparatus is 2-2.5 kg, with a filler it can reach up to 10 kg.

The invention is demonstrated by a specific example - photo 7. For rehabilitation, the author made a shell with a cover 50 cm wide, which corresponds to the width of the shoulders and 50 cm long. The height of the side surface of the projectile is 25 cm. Water in a volume of 3500 ml is used as a filler, which makes 32% of the total volume and the air pumped through the valve 6 by the pump. After filling the chamber with air, the projectile took the form of an ellipse, the bearing surfaces 8 and 9 became convex (radius). The side surfaces 4, forming a closed surface along the perimeter, prevent the projectile from “blowing” into the ball. The water used as a filler increased the weight of the projectile to 5.5 kg and increased its instability.

Thanks to the proposed technical solution, exercises of low and medium intensity became possible - aerobic loads, in which oxygen is the only and sufficient source of energy, anaerobic loads - in the form of projectile lifting (power) exercises in which oxygen is not involved in energy production, and energy is produced the account of the reserve of "finished fuel" contained directly in the muscles, as well as static exercises performed in a static (without movement) position at which this load gives the ma xymal load effect. The user can stand with his feet on the projectile, rest his knees or lie on his stomach, keeping the body balance on an unstable surface, perform exercises with the projectile in the air.

Thus, the design of the claimed sports projectile allows using the load on different groups of the user's muscles, significantly expanding the arsenal of exercises and their alternation, while the exercises with the projectile are safe and accessible to different categories of users. The invention expands the arsenal of sports equipment with an unstable surface.
