Description

The utility model relates to sports simulators and can be used to train the vestibular apparatus, relieve muscle tension, and prevent physical inactivity. Training the vestibular apparatus is very important for human health, as it is proved that the vestibular apparatus is responsible for the motor function of a person, orientation in space. The cerebral circulation and the state of the immune system depend on the work of the vestibular apparatus.

A chair is known comprising a seat mounted on a support, connected to the back by a hinge located offset from the back on elongated portions of the seat and back and equipped with means for supporting the user's torso made in the form of armpits and elbow rests; the support is equipped with a device for turning the seat around the vertical axis while the backrest is offset parallel to the plane of the seat (RF patent for IZ No. 2058104, IPC A47C 7/00 - analogue).

This chair does not allow training the human vestibular apparatus, as it is designed to cyclically twist the spine around the vertical axis clockwise and counterclockwise, while the feet and knees should not move.

The closest is an office or home chair containing a seat with a backrest and armrests mounted on a support, foot pedals built into the chair, which is an exercise bike mounted under the seat of a chair with pedals that are advanced forward (US patent No. 5470298, IPC А63В 23/035 - prototype) .

This chair allows you to simulate cycling and perform only one exercise with a rotational movement for the legs. In addition, the chair is bulky, takes up a lot of space, the pedals that move forward take up a large space in front of the chair and require additional efforts to set them into working position.

The objective of the utility model is to increase the efficiency of using the chair by expanding its functionality to provide training for the vestibular apparatus.

The technical result consists in increasing the degrees of freedom of movement of the chair by creating an additional kinematic connection between the pedal mechanism and the entire chair as a whole. This extends the functionality of the device as a simulator and increases the number of exercises that provide a comprehensive effect on the human body: it becomes possible to train not only the legs, but also the vestibular apparatus.

The task is achieved in that the simulator chair containing a seat with a backrest and armrests, foot pedals built into the chair, which is an exercise bike with pedals mounted under the seat of the chair, is rigidly mounted on a movable stand, made to rotate around its axis and installed in a stationary rack with a support with a fixed driven pulley rigidly fixed on a stationary rack, the device further comprises a drive mechanism consisting of a leading about a pulley located between the pedals on a frame mounted on the seat of the chair, a guide roller fixed on the frame, a tension roller mounted on the beam, a drive cable connecting the drive pulley and a stationary driven pulley, and the tension roller is connected to a tensioner consisting of a rocker arm , fixed at one end to the frame, and a tension cable connecting the other end of the beam to the manual lever-tensioner mounted under the arm of the chair under the fingers.

The task is achieved by the fact that the seat with backrest and armrests additionally contains safety belts.

Figure 1 shows a drawing of a simulator chair, side view; figure 2 is a top view of the working node of the simulator chair (kinematic diagram along the plane of the stationary pulley); figure 3 and figure 4 are photographs of the layout.

The device comprises a seat support 1, a stationary stand 2, a rotating stand 3, the chair itself (a seat with a back and armrests) 4, a drive mechanism frame 5, a tension roller 6 with a tension device (serves to move the tension roller), mounted on the beam 7, which at one end is attached to the frame 5, a guide roller 8, mounted on the frame 5, a drive cable 9, for example, a nylon or rubberized cord, a tension cable 10, a hand lever 11, a pedal (drive) mechanism: a drive drive pulley 12 and pedals 13, fixed pulley 14, Formation on the fixed rack 2. The rack 3 is rotated about its axis together with the seat 4, foot pedal (driving) mechanism and the frame 5.

The tension roller 6 is connected to a tension device consisting of a rocker arm 7, fixed at one end to the frame, and a tension cable 10 connecting the other end of the rocker arm with a manual tensioner lever 11, which is mounted on the arm of the chair under the fingers.

The device operates as follows.

The rotation of the chair is made by the muscular strength of a person engaged in a simulator. Before starting the workout, you must sit comfortably in chair 4. The back and armrests will help the trainee relax. If necessary, for example, a teenager can fasten safety belts similar to the safety belts in a car (not shown in the drawing), put your feet on the pedals 13, press the manual lever 11 on the armrest of the chair and begin to turn the pedals 13 forward or backward. In this case, the chair 4 together with the frame 5 and the pedal mechanism will begin to rotate clockwise or counterclockwise, respectively. When the pedals rotate, the drive cable 9 is tensioned. This force is transmitted through the cable 9 to the stationary pulley 14. As a result, a torque is applied to the system including the drive unit (drive pulley 12, pedals 13, frame 5 of the drive mechanism) and a chair 4 mounted on a rotating rack 3, which drives the entire system.

One pedal turn corresponds to one turn of a chair. If you want to continue the rotation of the chair without pedaling, you must press the manual lever 11 on the armrest, the tension of the drive cable will loosen, and the chair will rotate freely. To stop rotation, keep the pedals from rotating and press the manual lever 11. Stop will occur due to the clutch of the cable with the pulleys.

For better grip that prevents slippage, the drive cable 9 (for example, a nylon cord) is wound on the pulleys in one or two turns, and the primary tension of the cable is carried out by the tension roller 6, which also serves to guide the cable into the groove of the driven stationary pulley 14. If you make the cord rubberized, you can do without additional winding the cable on the pulleys. If necessary, you can reduce the diameter of the drive pulley to change the gear ratio of both pulleys and, as a result, reduce the load on the pedals and drive pulley. At the same time, the seat revolutions decrease, but the pedal revolutions increase.

So that the drive cable does not slip from the pulley of the pedal mechanism 12, a guide roller 8 is installed on the frame, which guides the cable into the groove of the pulley 12.

Figure 3 of figure 4 presents the current model (layout) of the simulator chair, made of ordinary home or office chair on wheels. Dimensions of the sample (mm): height, width, length, respectively 810 × 450 × 1200. Weight is 15 kg. The prototype was tested, proved its efficiency and confirmed the claimed objectives of the utility model and technical result. The wheels in this device will provide easy movement of the chair in the room to select a place for training. The best option is wheels that hold the weight of the chair due to rubber pads on the vertical axes of rotation of the wheel blocks. When landing on a chair, the gaskets are deformed and the protruding part of the vertical axis rests on the floor, thereby ensuring the necessary stability and stationary support of the chair, that is, self-locking wheels are used that lock when the person is seated in the chair and prevent the simulator chair from moving.

As for classes on any simulator, you must follow some rules. The last meal and water should be at least 1 hour before training. People with poor health are advised to exercise under the supervision of another person. In playing places and places of rest it is necessary to protect the simulator from getting people under it. Subject to the rules of installation and fencing, the simulator is safe for the trainee and others.

Thus, in comparison with the prototype in the inventive simulator chair, the efficiency of using the chair is higher due to the expansion of its functionality to provide training not only legs, but also the vestibular apparatus. An additional kinematic connection between the pedal mechanism and the entire chair as a whole increases the degree of freedom of movement of the chair, which expands the functionality of the device as a simulator and increases the number of exercises that provide a comprehensive effect on the human body.

The claimed utility model is simple in design, takes up relatively little space and can be used independently by people of any age at any time to train and strengthen the vestibular apparatus, relieve static muscle tension and prevent physical inactivation in gyms, fitness clubs; for relaxation and training at home; as an attraction and. simulator in recreational areas, in playgrounds, in kindergartens, schools; for training and strengthening the vestibular apparatus in health institutions: sanatoriums - dispensaries, physical rooms, clinics; at workplaces in offices to restore performance.
