Description

The invention relates to training devices, and in particular to devices designed for training the upper limbs.

It is known that the most physiological movements are used to train the muscles of the hands - similar to those often used in real life. The principle of operation of most simulators is based on the elastic deformation of springs - rubbers and other elements. For example, classic hand expanders in the form of a rubber ring or two handles connected by a spring to simulate the compression of fingers into a fist. There are also simulators for the muscles of the flexors and extensors of the hand, which are two handles on the same axis, rotating relative to each other through a friction element, by adjusting the resistance force of which an increase or decrease in load is achieved.

The device http://wringitout.com/ is known (06/05/2019) the basic principle of which is the rotation of the hands with overcoming the resistance force of spring-compressed friction discs.

A device is known - a simulator KISTEKRUT SILARUKOV www.silarukov.rf / silarukov-wrist-roller-exeroser (05/06/2019) whose arms rotate through a friction element.

A significant drawback of the above constructions is the worst, in comparison with the proposed invention, characteristic of the absorption of energy of hand movement - in simulators with elastic elements, the energy absorption is almost zero, and with a friction element based on friction, there is a pulling moment - rest friction - which is significantly higher, than sliding friction, which creates discomfort, trauma and inconvenience in the use of such simulators. Also, this principle bears the inability to create a progressive load characteristic during the exercise.

The technical result of the invention is the ability to provide optimal load characteristics without stragging and progressively increasing load - from simple to complex, as well as improving the effectiveness of training.

The technical result is achieved through the use of a replaceable deformable element. As part of a continuously performed exercise, there is an ultimate goal - the destruction of a removable element (metal bar) is correspondingly significantly higher motivation for the training athlete, which contributes to significant interest and excitement during training, respectively increasing its effectiveness.

The operating principle of the simulator is based on the plastic deformation of twisting of a metal bar installed inside the parts of the simulator body that are relatively movable relative to each other and fixed at both ends by metal clamps on the parts of the body to give it a fixed position relative to both parts of the body, respectively. Rotating relative to each other the parts of the body that are the handles of the simulator or the place of their attachment, the trainee deforms the bar located inside the simulator, thereby doing useful work and getting the necessary load on the muscles of the hands and shoulder girdle.

A sports simulator for developing the strength of the forearms and muscles of the shoulder girdle is shown in FIG. 1, where 1 is the clamp of a replaceable element - a metal bar, made with the possibility of fixing the bar of a given section shape and size; 2 - bolts tightening the clamp; 3 - holes of a given shape for installing a removable element of a metal bar; 4 - tube-body simulator; 5 - pipe insert in the housing connecting the two parts of the simulator in a movable for rotation connection; 6 - rubber handles, dressed on the pipe of the body and glued to it to avoid turning; 7 - interchangeable element - a metal bar made of a material having the ability to plastically deform when twisted with the possibility of fixing in clamps.

In FIG. 2, FIG. 3 and FIG. 4 shows photographs of a prototype device.

A sports simulator for developing the strength of the hands, forearms and muscles of the shoulder girdle works as follows: a replaceable element is inserted into the hole 3 of the clamp 1 from the inside - a metal bar 7 and clamped with bolts 2, then the second part of the simulator body 4 is put on before the entry interchangeable element 7 into the hole 3 of the clamp 1 and is also clamped by bolts 2, the simulator is taken by the handles 6. The handles can be part of the simulator 4 body, or can be attached to the body 4 in a different position of FIG. 4, allowing to train other muscles of the forearm. The material from which the bar is made and its geometric dimensions are selected individually, depending on the level of preparation of the person.

In the process of training, bending or bending movements are made by hands, rotating the halves of the simulator case relative to each other, as a result of which the replaceable element inside the simulator - a metal bar - twists along the axis, plastic deforming and creating resistance to the actions of the athlete the stronger, the greater the number of revolutions was twisted. Thanks to the effective conversion of the energy of hand movement into the internal energy of the replaceable element, the highest impact on the athlete’s muscles is achieved, and the increasing resistance as the bar is twisted - a progressive characteristic allows you to increase the load directly during the exercise. The use of a replaceable element subjected to plastic deformation is a key point in the work of the simulator. Changing the diameter of the interchangeable element leads to a change in load and is selected before the start of the exercise. The destruction of the replaceable element occurs at the moment when the stresses in it reach the ultimate strength, which is a motivating factor for the athlete, gives him a visible goal and increases his interest in achieving it.

An example implementation of the invention is shown in FIG. 2, 3, 4. In the prototype, a rod of steel 3 with a diameter of 6 mm and a length of 340 mm was used as a deformable element. The destruction of the element occurred on average after 1,500 rotational movements. After destruction, the element was replaced by a new one. The material of the bar and its dimensions were selected depending on the current task during the training of the athlete.

The simulator can be used to effectively train the muscles of the hands, forearms and shoulder girdle of athletes of any level of preparation, both at home and in the gym.
