Description

Description of the invention

The utility model relates to sports, in particular to devices used to improve 2 the physical development and sportsmanship of wrestlers, various wrestlers, and arm wrestlers.

A well-known device for training muscles, which has two hinged tubes, each of which carries a handle and a means of loading in the form of a spring covering a Hook hinge (a. st. USSR Mo1639677, AbЕ3В23/00,

Bul. Mo13, 1988).

The disadvantage of this device is that it does not meet the needs of armwrestling athletes, because the biomechanics of a different structure are embedded in it, and although this device is portable and provides the development of the strength qualities of the hands, the motor skills and skills it creates are far from what is still needed by athletes of this type of power struggle.

A well-known device for training the strength endurance of the muscles of the arms, made in the form of an L-shaped rack, installed on a base and fixed with two elastic bands, and a spring is vertically installed on the rack, to which a handle for the athlete's hand pressed to the base is attached 12 (US patent Mo4108429, published on August 22, 1978.

The disadvantage of this device is that the athlete has to squeeze the handle, and not move it in the direction required for arm wrestling, and besides, it does not have a means of evaluating feedback, which reduces its value in the training process.

A well-known training glove for improving the muscles of the hand, which has a means of fastening on the athlete's hand, | two pockets in which cylindrical levers are placed - from both sides of the hand and additional weights on the elbow part of the hand (US patent Mo4330120, publ. 05.18.821.

The disadvantage of this glove is that although it is portable and promotes the development of strength qualities, it is not the muscles that arm wrestling needs.

A well-known device for developing the strength of an athlete's hands, which has a lever with a handle for grasping by hand, is hingedly installed on the base and is spring-loaded to it with a helical spring with the possibility of changing the resistance force and the height of the lever (US patent Mo3947025, Publ. 30.03.76.

Its disadvantage is that the base is fixed only by hand, and therefore significant loads on the lever are impossible.

In addition, the support platform does not correspond to the directions of force actions with a lever, which are inherent in arm wrestling, and there is no means of feedback. -

The closest in technical terms is a device for training the arms and shoulder girdle, which has a body with a Ge recess for the elbow and a lever with a handle, connected to a loader, made in the form of a system of springs mounted on shafts and transmitting movements to a mechanism for determining physical tension athlete (pat. USA juju

Mo3982757, publ. 28.09.76). at

The disadvantage of this prototype device is that, although it has such a lever that it would be possible to use it in arm wrestling, and has a means of feedback on physical load, it is heavy and unstable, because it has an inconvenient massive shape and must be attached to some support. The main thing is that it is not adapted for high loads, which are characteristic of modern arm wrestling, and the movement of the lever - its trajectory shape and direction of movement do not meet the needs of this sport. "

The basis of a useful model is the task, taking into account all the positive qualities and shortcomings of the prototype device for arm and shoulder girdle training, to create another device that athletes could use specifically for arm wrestling with all the needs of this sport: that it should be light, convenient, portable type; so that it would be possible to use it for training alone in the gym, at home, at work, in transport during long trips to competition cities, and in places of rest. This was supposed to be achieved thanks to the use of supermagnets as a physical load. These elements are available for use in the field of technology for portable devices. They are the most promising, because they do not need springs, shock absorbers, or other complex mechanisms, and they do not need energy carriers. o The task is solved by the fact that in a portable simulator for arm wrestling, which has a support base and an elbow rest and a lever with a handle installed on it, are structurally connected to a loader and a means of determining the athlete's physical effort. According to the useful model, the support base is made in the form of a 20" magnetic disc with an elbow rest with the possibility of fixing them with a clamp attached to the support base and covering the edge of the cover of any table. At the same time, the loader is made in the form of two permanent "magnets with rare earth elements, directed by their different poles to each other, one of which is located in a nut screwed onto the lever, and the second - in a magnetic disk on a support base, on which the lever rests, fixed from below passing magnetic lines of force through the support disk, which coincides 25 in area with the magnetic disk, while the means of determining the athlete's physical load is made in the form of a measuring scale applied to the threaded surface of the lever, the index of which is the edge of the nut screwed onto it.

The technical and consumer result, achieved thanks to the use of the entire set of distinguishing features of the proposed device, is that it was possible to replace the heavy and structurally complex loader of the device with a pair of super-powerful magnets with rare earth elements and thus ensure the portability of the device at a high power of its loader.

The essence of what is proposed is explained by the drawing, where Fig. 1 shows the moment of use of the arm wrestling simulator, side view; in Fig. 2 - the same, front view; in Fig. 3 - simulator, front view, enlarged; because in Fig. 4 - the supporting base of the simulator with a magnet, top view;

in Fig. 5 - simulator, side view, enlarged; in Fig. 6 - the diagram of the interaction of the magnets of the support base; in Fig. 7 - training cover, in axonometry; in Fig. 8 - possible types of instruction handles; in Fig. 9 - a spring check in the fixing hole, side view.

In particular, the arm wrestling simulator has a support base 1, on the surface of which a magnetic disk 2 is attached, and behind the base I is attached an elbow rest C with a clamp 4 and a movable arm shoulder fixator 5. A support disk 7 is attached to the base I with a magnetic nut 6, on which in a lever 8 with a handle 9 is attached to the center, 7/0 a cover 10 is used to carry the device (Fig. 1-9).

Magnetic disk 2 of the support base | has on its surface an annular groove ІІ, into which, when tilted, the support disk 7, perforated with holes 12, is placed and fixed. ring 14, on the side of which plate grippers 15 are attached. A clamp 4 is attached from below to the base and covers the edge /5 of the cover 16 of the table and fixes the simulator on it with a pair of screws 17.

Nut 6 and disk 2 have permanent magnets 18 with rare earth elements (MagevB). On the outside of the nut, gripping bumps 19 and a threaded channel 20 are made, with which it is screwed onto the external thread, which is made in the form of a tube 21 of the telescopic lever 8, on the upper tube 22 of which a handle 9 from the set (Fig. 8) is mounted. The tubes of the telescopic lever 8 are made a series of holes 23 for insertion when changing and setting the length of the elastic check 24. To improve the passage of the lines of force of the magnets 18, holes 25 are made in the disc 7, and a scale 26 for determining the power of the interacting magnets is applied to the pipe 21 of the lever 8 for setting the load and receiving feedback recalculation to physical load in millimeters.

The simulator is used by athletes engaged in a special type of wrestling - in a pose, sitting at a table, competing in pairs, grabbing each other's hand, to bring it from a vertical position to a horizontal position (Fig. 1, 2). But this simulator can be successfully used for therapeutic gymnastics and in general by those who are engaged in comprehensive physical exercises. -

For training, remove the simulator from the cover 10, fasten it with a clamp 4 to the strong cover 16 of any table and put on the end of the tube of the telescopic lever 8 the corresponding handle 9 from the cover set (Fig. 8), insert the support disk 7 of the lever 8 into the support base | so that its lower plane - z adjoins the plane of the support and its edges coincide with its circular groove II. And then the athlete sits on a chair and performs static and dynamic exercises first with one, and then with the other hand (Fig. 1, 2). During exercises b" with static loads, he tries to move the lever from its place, pressing on it with the active hand (the other hand rests on the table in a state of rest and relaxation).

At the same time, the nut 6 is screwed onto the lever 8 as low as possible to bring its magnet closer to the magnetic disk 2 с2

FUNDAMENTALS I. These magnets are multipolar and are designed for a force of attraction higher than the capabilities of athletes of this type of sport. During training, the athlete repeatedly tries to move the lever 8 in any direction from the original vertical position with appropriate periods of rest, but the lever remains unmoved because the magnets are very close to each other. The main exercises on the simulator are dynamic movements and dynamic physical load. To do this, the nut 6 is unscrewed - it is fed upwards, " Move the specified magnets away and weaken the force of their mutual attraction. At the same time, the lever 8 is subjected to movements with c when the athlete's hand presses on the handle 9 in any radial direction, relative to the initial position (Fig. 3). At the same time, the physical stress on the athlete's hand will initially be significant in order to move the lever 8 from the original vertical position. But, the further the lever moves from the center of the base, the more the magnets of nut 6 and disk 2 of base I move away from each other, and the force of attraction gradually decreases. AND

From so on, the amount of load on the athlete's hand will decrease until lever 8 takes a horizontal position - diagram, Fig.b6. The lever 8 and its disc 7 are not separated from the base I, because they are mutually fixed both in the process of movement and in the final position by the lever II on one side and the athlete's hand on the side of the handle 9 (Fig. b). The initial vertical position of the lever 8 after loading sl is established by lowering it - by relaxing and removing the tension of the muscles of the hand on the handle 9. The lever independently 5or Under the influence of the indicated magnets takes the initial vertical position and is reliably fixed in this due to (Ce) the tight fit of the disk 7 on the plane disc 2 of the base I (Fig. 5, b). It is possible to perform dynamic exercises inherent in arm wrestling and other training actions in any radial direction (Fig. 3, 4) with the possibility of various grips of different removable handles 9 (Fig. 8) and setting the appropriate load by changing the length of the telescopic lever 8 (thanks to the rearrangement of the check 24 in the holes 23) and, most importantly, due to the movement of the nut 6 on it, that is, the distance of the magnet from the base | - disk magnet 2, because these magnets have rare earth elements and therefore fall with supermaximal magnetic capabilities - See NEru/LMmlalm.dapv-dava.sot/tadpeiv. sweat; peru/lumlu.atahipdtadpeiiv.sot/;. pEr//ALumlu mopaegtadpeiv.soti| Magev magnets, which ensures high physical loads, characteristic of this type of sport. After training, the lever 8 is separated from the base І, screwing the nut 6 in advance towards the handle 9, and the components of the simulator are placed in the cover 10, which is made of magnetically protective material.

The technical and consumer advantage of the proposed simulator over the prototype is that it more accurately and adequately modulates the actions of an armwrestling athlete and provides high physical loads.

This gives him the opportunity alone, in the absence of an opponent in any conditions, to prepare for the competition in a high-quality way, 65 With the fans of this sport to improve not only professional sports skills, but also his entire physical status.

The exercise machine can also be useful in the field of therapeutic gymnastics.
