Abstract

The utility model relates to sports equipment, namely to power simulators with free weights and is intended for the development of leg muscles. The proposed utility model is aimed at the possibility of changing the load during the exercise. The technical result is achieved by the fact that the main frame using two hinges and a chassis the nuts are connected to a movable frame on which the seat is installed, the guide carriages and the carriage, and also on the main frame there is a regulating mechanism consisting of a gear motor, chassis Inta, limit switches and a joystick mounted on the seat.

Description

The utility model relates to sports equipment, namely to weight training equipment with free weights and is intended for the development of leg muscles.

Existing constructions of the “Leg Press” simulators do not allow changing the load during the exercise (approach) or between movements in the approach. The guide carriages are rigidly connected with the main frame or with other structural elements, unlike lever-type simulators that do not have guides and carriages that differ in immersion dynamics, and also do not allow the athlete to make efforts to vary during the exercise

Known Matrix magnum MG - PL 70, containing the main rvma, carriage, carriage latches, adjustable seat for the student (matrixfitness.ru).

The disadvantages of this device:

- the inability to correct the magnitude of the load during the exercise;

- lack of effectiveness of the training process;

- a high degree of injury when performing exercises with large weights.

Known prototype device Bodi Solid LVLP, containing the main frame, guide carriages, carriage latches, adjustable seat for the student (Bodisolid.com). The disadvantages of this model:

- the impossibility of changing the angle of inclination of the guides and the carriage during the exercise;

- when changing the angle of inclination of the guides, it is necessary to adjust the seatback.

The proposed utility model is aimed at the possibility of changing the load during the exercise.

The specified technical result is achieved by the fact that the main frame is connected with a movable frame with two hinges and a running nut, on which the seat, the guide carriages and the carriage are installed, and also on the main frame there is a regulating mechanism consisting of a gear motor, spindle, end switches and a joystick mounted on the seat.

The proposed simulator design allows you to change the angle of the carriage rails during the exercise, which provides changes (increase, decrease) in the efforts of the athlete. As the athlete’s muscle fatigue increases, when performing the task, the effectiveness of the movement decreases. To do this, you have to use the help of hands, the help of other athletes (a trainer), or completely stop the exercise.

Also, with improper weight selection, it becomes possible to adjust the applied efforts without leaving the simulator. The psychological attitude to fulfill the task does not change.

The indisputable advantage of this model is a significant reduction in the risk of injuries to the knee joints during the last repetitions, when there is a need to reduce working weight.

The proposed utility model is illustrated Fig., Where:

1 - main frame;

2 - movable frame;

3 - hinge;

4 - guide carriages;

5 - carriage;

6 - a running nut;

7 - lead screw;

8 - gear motor;

9 - regulatory mechanism;

10 - limit switches;

11 - joystick;

12 - seat.

A movable frame (2) is fixed on the main fixed frame (1) with two hinges (3), and also on the main frame (1) a control mechanism (9) with a gear motor (8) and a spindle (7) is installed. The lead screw (7) is screwed into the lead nut (6) mounted on the movable frame (2). Guide carriages (4) and carriage (5) are installed on the moving frame (2), and a joystick (11) is fixed on the seat (12). Two limit switches (10) are installed on the main frame (1).

The main frame is a rectangular structure made of a profile pipe, and has sufficient strength and rigidity. Its dimensions exceed the dimensions of the movable frame in length and width, this is due to the necessary stability of the entire structure. The simulator has a regulating mechanism (9), which is fixed by the lower part through the hinge (3) to the main frame (1).

The regulating mechanism (9) is arranged as follows: the lead screw (7), which moves the movable lead nut (6), receives rotation from the reversing gear motor (8). The lead screw (7) abuts against the frame of the regulating mechanism (9) with its lower end and is mounted on it. The movable running nut (6) is mounted on the movable frame (2).

Limit switches (10) are fixed on the movable frame (2).

Within the reach of the hands (right or left), the tilt joystick (11) is installed at the end of the seat (12).

Limit switches (10), joystick (11), control unit of the regulating mechanism (9) are connected in a single electrical circuit. The control unit and the gear motor is powered by a voltage of 12 V through an adapter, which is taken out for the design of the simulator and connected to a 220 V network.

The angle of inclination of the movable frame (2) can be carried out by an athlete who is on the seat of the simulator, and outside it, as follows. The joystick (11) has three positions: increase the angle, neutral and decrease the angle. The initial position of the joystick handle is neutral, i.e. in the middle. In the initial position of the movable frame (2), the angle of inclination of the guides of the load carriage (4) is 60. To increase the inclination of the movable frame (2), you must move the joystick handle to the “increase angle” position, then rotate the spindle electric circuit and gear motor (7) ) will begin to move the travel nut (6) up, changing the position of the guides (4). When the desired angle is reached, you need to release the joystick handle and the rotation of the spindle will stop.

When decreasing the angle, you need to move the joystick to the "decrease angle" position and the mechanism for changing the angle will work in the opposite direction. When the movable frame reaches its extreme positions, the limit switches (10) are activated and the movement stops.

The proposed utility model makes it possible to change the load during the exercise, eliminates the possibility of traumatic situations when working with maximum load, increases the effectiveness of the training.

Claims (1)
