Abstract

FIELD: training equipment. SUBSTANCE: mechanical arm has tubular pole composed of telescopic parts. Tubular portion of pole having maximum diameter is attached to transverse pipe axially aligned with sleeve and horizontal shaft, which is attached on bracket. Bracket, in its turn, is joined to vertical shaft fixed on base of mechanical arm. Other end of tubular portion of pole having maximum diameter is provided with opening for fixing tubular portion of pole having minimum diameter. The latter has set of openings positioned at its one end and adapted for adjusting arm height, and bead welded to its other end. Handle is put onto pole and is continuously connected to bracket. Bracket is connected through cable to variable resistance unit of arm-wrestling exerciser. Mechanical arm is further provided with attachment extending from base to tubular portion of pole having maximum diameter. EFFECT: increased efficiency in arm-wrestling exercising process, simplified construction and enhanced reliability in operation. 2 cl, 3 dwg

Description

 The invention relates to training devices and is intended for the development of muscle strength in the hands.

 Known device (USA, Hobby J.M. Pat. N 3947025 Armwrestling unit - Pu, l. 30.03.76) "Desktop training device" containing a rectangular base, fixed on the table surface by means of adjusting clamps. A support structure is rigidly fixed on the base, inside of which there is a cylindrical rod pivotally connected to the movable lever. From the opposite end, the rod passes into the L-shaped rack, connected by means of springs with a movable tension element. Work on the device comes down to moving the lever in the transverse direction due to bending of the arm in the elbow joint.

The disadvantages of this device are:
- not provided for a device with which you can more effectively develop the muscles of the flexors of the hand;
- limiting the degree of rotation of the lever (mechanical arm), rotation occurs only in the frontal plane;
- the absence of a change in the length of the lever (mechanical arm) in accordance with the length of the athlete's forearm.

 A device (USA, Hobby J.M. Pat. N 3947025 Armwrestling unit - Publ. 30.03.76) "Device for the development of muscle strength of the hands", consisting of a base and two angular brackets fixed to its surface. A tubular sleeve is installed between the brackets, which is a tight seat for a coil spring. A handle shank having an elastic coating is welded to the outer end of the spring. A bolt with a wing head on the upper surface of the sleeve serves to hold the coil spring in a predetermined position. When using the device, the wing screw with nuts is loosened, a spring with a given strength and rigidity is inserted into the sleeve. Then the bolt is tightened, and the angle of the sleeve is selected so that the height of the handle corresponds to the dimensions of the athlete's hand.

 The disadvantage of this device is that there is no connection with the node of variable resistance, which limits the effectiveness of the training.

 The aim of this invention is to increase the efficiency of the training process of arm wrestlers.

 To achieve this goal, a mechanical arm for arm wrestling is made tubular from telescopically articulated parts. The tubular part of the rack with the largest diameter is fixed to the transverse pipe, which is coaxial to the sleeve and the horizontal axis, mounted on the bracket. In turn, the bracket is connected to a vertical axis fixed to the base of a mechanical arm. At the other end of the tubular part of the rack with the largest diameter, there is an opening for fixing the tubular part of the rack with the smallest diameter, which has a number of holes at one end for changing the height of the hand, a shoulder is welded on the other end and a handle is put on the rack, which is inseparably connected to the bracket, through which it is connected via a cable to a node of variable resistance of the armwrestling simulator. The mechanical arm contains a mount from the base to the tubular part of the rack with the largest diameter of the armwrestling simulator.

 In FIG. 1 shows a mechanical arm for arm wrestling, FIG. 2 is a left view thereof, in FIG. 3 shows a simulator for arm wrestling with a mechanical arm connected by a cable to a node of variable resistance.

 The device depicted in FIG. 1, contains a base 1, on which the axis 2 is mounted, for rotating the mechanical arm in a vertical plane, a stop screw 3 and fastening the mechanical arm 4 from the base 1 to the tubular part of the rack with the largest diameter of the armwrestling simulator. The mechanical arm is made tubular from telescopically articulated parts. On the axis 2, a bracket 5 is fixed with a horizontal axis 6, on which a sleeve 7 and a pipe 8 are mounted, connected to the tubular part of the rack with the largest diameter 9 of the mechanical arm. The tubular part of the rack with the smallest diameter of 10 at one end has a number of holes for changing the height of the mechanical arm using a bolt 11, and a shoulder 12 is welded on the other end and a handle 13 is worn, to which the bracket 14 is inseparably connected and is connected to the variable assembly via a cable 15 resistance 17 simulators for arm wrestling. On top of the handle 13 is fixed on the tubular part of the rack with the smallest diameter 10 of the bolt 16.

 Before starting the exercise, the required height of the mechanical arm is established taking into account the length of the trainee's forearm. On the site of variable resistance of the simulator for arm wrestling, the springs set the necessary load and the necessary training mode. By turning around the vertical axis 2, the mechanical arm is set so that it is possible to tilt the mechanical arm around the horizontal axis 6 in the direction of the competition exercise. The trainee assumes the initial position for performing the competitive exercise, captures the handle 13. When performing the exercise, the trainee simultaneously with the bending of the mechanical arm rotates the handle towards himself. Returning the mechanical arm to its original position, you can repeat the movement. Due to the fact that the thrust of the alternating resistance unit of the simulator for arm wrestling is connected via an arm 14 to a handle 13, which is located on the upper end of the tubular part of the rack with the smallest diameter 10, with the possibility of its rotation, conditions are created for the most efficient development of muscles that perform work during movement hands, forearms and shoulders.
