IMPLEMENTATION OF THE UTILITY MODEL

All components of this utility model are described in detail below with reference to the drawings and the reference positions indicated on them for a more complete understanding of the scope and all technical aspects of the claimed technical solution by a person skilled in the art.

In fig. 1 shows the proposed simulator.

Lifting roller blocks 1 are fixed, for example, by screwing or welding on the mounting posts of the load guides 2, and participate in the movement of the cable 14 at the moment of lifting and lowering the load 5. They are a structure consisting of an external metal frame and a roller fixed inside.

The racks for fastening the load guides 2 create the power frame of the simulator for fastening and connecting into a single system the load platform 6, load guides 3, load roller blocks 4, transmitting roller blocks 7, lifting roller blocks 1, changing the angle and plane of the roller blocks 8 They are square metal parts welded together into a single element and securely fastened to the frame 10.

The load guides 3 are securely fastened to the mounting posts of the load guides 2 and are designed to move along them and securely fix the load 5 vertically when lifting and lowering. It is a structure consisting of an external metal frame, for example a metal pole.

The roller blocks of the load 4 are securely fixed on the surface of the sheet securing the load 5. They are designed to lift the load 5 and self-level it. It is a structure consisting of an external metal frame and a roller fixed inside.

A load with the possibility of increasing (decreasing) weight 5 is a set of weighting plates to counterbalance the athlete’s effort. By rearranging the adjustment pin, the number of plates, that is, the weight of resistance to the athlete’s effort, changes.

The load platform 6 is securely connected to the frame 10, is the basis of the power part of the simulator and is intended for attaching load guides 3, load roller blocks 4, weight 5, transmitting roller blocks 7, lifting roller blocks 1, changing the angle and plane of the roller blocks 8. It is a metal stand for the load 5 in the rack for attaching the load guides 2.

The transfer block-rollers 7 are securely fixed on the load platform 6, designed to supply the cable 14 to the lower part of the power part of the simulator, changing the direction of the cable 14 from vertical to horizontal and the direction of the cable 14 to the block-rollers 8 changing the angle and plane. It is a design consisting of an external metal frame and a roller fixed inside.

The roller blocks 8 changing the angle and plane are securely fixed on the load platform 6 and are designed to remove the cable 14 from the load platform 6 to the podium platform 11.

Guide block-rollers 9 are securely fixed on the load platform 6, designed to guide the cable 14 to the bar with the main blocks by rollers 13. It is a structure consisting of an external metal frame and a roller fixed inside.

The frame 10 is the basis of the part of the simulator on which the athlete performs exercises and is intended for connecting the guide block-rollers 19 into a single system, attaching the cable pre-tensioning posts and holding the bar 12, for example by welding, attaching the podium platform 11, for example by screwing, attaching the electric winch 15, acts as a frame "U"-shaped metal frame.

The podium platform 11 is securely fastened to the frame 10 and is designed to support the athlete during the exercise and installation of the bench for the bench press. The platform can be, for example, wooden flooring covered with metal, rubberized elements and others.

Racks for pre-tensioning the cable and holding the bar 12 are securely fastened to the frame 10, designed to hold the bar with the main pulleys-rollers 13 before the start of the exercise and immediately after the end, pre-tensioning the cable 14 on the bar with the main pulleys-rollers 13. It is a metal stand for holding vulture.

The bar with the main roller blocks 13 is securely attached to the cable 14, placed on the racks for pre-tensioning the cable and holding the bar 12. It is the closing part of the simulator and the entire pulley system to create force for the athlete and transfer this force to lift the load 5.

The cable 14 transmits the application of the athlete's effort through the bar with the main roller blocks 13 to the load 5. The cable 14 can be made of durable material, for example steel.

The electric winch 15 is securely fastened to the frame 10 and the platform of the podium 11, is designed to regulate the length of the cable 14 when performing various exercises, sets the pretension of the cable 14 on the bar with the main roller blocks 13, when the bar with the main roller blocks 13 is on the cable pretension stands and holding the bar 12.

The device operates as follows.

The development is a product made using a pulley system.

The principle of operation when deadlifting is that the athlete installs the bar with the main roller blocks 13 at the required height on the height-adjustable cable pre-tensioning and holding the bar racks 12. The required weight of the load 5 is set. The effort to lift the load 5 applied by the athlete is multiplied by two using a pulley system. Having fixed the load 5, the simulator with the help of a chain hoist transmits double force and an additional 2-4% increase due to friction and sliding of the cable 14. Using the electric winch 15, the slack of the cable 14 is removed, which leads to the creation of pressure on the cable pre-tensioning posts and holding the bar 12. The athlete develops effort throughout the entire exercise with a constant load equal to the load 5 times two. In the event of the bar with the main blocks-rollers 13 falling out of the athlete’s hands, the force on the bar with the main blocks-rollers 13 disappears as soon as the load 5 falls into place, that is, below the level of the starting point of lifting the bar with the main blocks-rollers 13. B in the event that there was oscillation of the bar with the main blocks-rollers 13 vertically and the bar with the main blocks-rollers 13 did not return to the racks for pre-tensioning the cable and holding the bar 12, having passed the starting point of movement, the bar with the main blocks-rollers 13 falls onto the podium platform 11 , having only its own mass.

When performing a bench press, the athlete, using an electric winch 15, removes the cable 14 to increase the height of the bar with the main roller blocks 13, installs a bench, and adjusts the height-adjustable cable pre-tensioning and bar holding posts 12 to the required height. Next, the exercise is performed in the same way principle, as during the deadlift. If the bar with the main roller blocks 13 falls out of the athlete’s hands at the top point, the bar with the main roller blocks 13 falls down, but at the moment it touches the athlete’s chest it only has its own mass, since the bar with the main roller blocks 13 falls below the initial lifting point, as a result of which the load 5 is lowered onto the load platform 6 and stops influencing the bar with the main roller blocks 13 before the bar with the main roller blocks 13 falls on the athlete’s chest. Thus, the simulator eliminates such injuries and allows the use of the simulator with critical weights without a belay partner.

The principle of operation when performing squats with weights is exactly the same as when performing the two previous exercises, taking into account preliminary adjustments with an electric winch 15, a cable 14 and cable pre-tensioning and bar holding racks 12.

Thus, a device of increased efficiency has been created for training in three main exercises in powerlifting: deadlift, chest press while lying on a bench, squats, the declared technical result has been achieved.
