Description

The invention relates to sports and medicine, in particular to small-sized prefabricated trainers for the training of all body muscles, as well as therapeutic gymnastics.

Known Lightweight Exercise Machines e.g. US, no. 5284462, TPK ⁵ A63B 21/00, designed mainly to train the muscles of the hands and the treadmill DE no. 4238824 TPK ⁵ A63B 21/00 for training hands and feet.

The drawback of these trainers is the limited amount of muscles they train and the uneven load over the entire trajectory of the body part they train.

There are also known trainers that allow many muscles or groups of muscles to be exercised, e.g. SU copyright no. 1623669, A63B 17/04, but they are very sophisticated, bulky, fit for gym use.

The closest to the patented one is a trainer (RU, No. 2050881 A63B 21/012, 23/00) consisting of a horizontal frame with a gym mat, a vertical support fixed to the frame with adjustable hinges, and a flexible cable. Removable elements that can be fixed anywhere along the uprights are mounted on the uprights: the load units, the armrests in the form of a lever arm, the footrest and the top transom. The main element is a load unit consisting of a series of lever mounted on the shaft with interchangeable means of movement, two springs, which include a vibrator, as well as a stop unit and a ratchet. The brake unit consists of two discs. One disc is fixed, fixed to the housing, and the other is fixed, fixed to the shaft. By rotating the lever on the handle, the latter disc rotates together and, due to friction, the resistance of the fixed disk is a load on the action being performed. The degree of clamping of the discs and thus the load is controlled by a nut and a spring. The vibrator is mounted on a shaft between the lever and the braking unit's stationary disk, consisting of a ring with fingers inserted into the holes in the stationary disk and resting on corresponding recesses on the surface of the top of the movable disk. The ring is pressed from above by a spring, over which a nut - a flywheel - is screwed on the thread of the shaft. The vibrator can be switched off or the vibration magnitude can be adjusted thanks to a nut - a flywheel that presses or releases the spring. The ratchet mechanism has triangular plates, shamrically mounted and radially disposed on the fixed disk, and balls placed between the triangular plates and the moving disk of the braking unit. The loading device, by means of an attachment consisting of a detachable bracket and a friction plate, is attached to the upright in such a way that it can change the angle of displacement with respect to the upright in the X and Y planes. For exercise, the load generator creates a clockwise rotation of the load while allowing the muscles to relax in the opposite direction. This process is regulated by the racket mechanism.

This simulator also has drawbacks: the ability of the loading device to change the inclination angle of the strut limits only the amount of muscle to be trained in the X and Y planes, and creating a uniform load for clockwise, anti-clockwise, and no direct load results in high training efficiency.

The object of the invention is to extend the capabilities of the simulator, to improve its ergonomic features and to increase the efficiency of the training.

This problem is solved by a multifunctional prefabricated simulator consisting of one or more load units, each mounted on at least one beam, with the possibility of changing the anchorage along it and a set of movable means for movement, and the load unit having a connecting unit the vibrator, the ratchet mechanism, and the braking assembly, wherein the loading device further comprises a first motion direction indicator unit, a spring unit and a second motion direction indicator unit between the coupling unit and the racket mechanism, and the vibrator is connected to the first or second motion direction indicator unit the ratchet mechanism is connected to the stop unit via the gear unit, and the loading device has a second ratchet unit connected to the second stop unit via the second gear unit, with the second ratchet mechanism rotating in the same direction a spring is provided at the shaft as the first and between both ratchet mechanisms, and a first block angle lock is engaged between the junction body and the first motion direction block body, and a second block angle lock between the first motion direction block body and the spring block body , and between the second body of the direction of motion unit and the body connecting the two ratchet mechanisms, both gearboxes and both braking units, the third block angle lock is engaged, and the joint unit has two perpendicular multi-directional input shafts, the first of which is parallel. X, and second for Y, with a tapered pin at each other end, the conical pin being parallel to the Y plane, coupled to the spindle connecting assembly with the first motion direction block, and the first motion direction block. has two stat articulating each other with bevel gears of which a plane parallel to the X is mounted on a spring block and a gear parallel to a Y plane is mounted on a multi-axis shaft which is an auxiliary input of the first directional unit and connected to a shaft of the coupling assembly; , the spring unit having a shaft on which one or more cylinders are mounted, each having a spring with one end connected to the cylinder body and the other to the shaft, and a locking element coupled between the housing and the cylinders, that the second directional drive unit has two orthogonal conical gears, one of which is parallel to the X plane and is connected to a multi-axis spindle which is the auxiliary input of the second motion directional block and the other gear parallel to the Y plane of the shaft connecting it to r the ratchet mechanism, and the ratchet mechanism having a shaft for sequentially positioning the rotatable and pivoting pulleys interacting with the inclined rivets on a flat surface of each pinion facing in opposite directions when the pivot pinion is fixedly movable but inclined and the pivot pinion has a fixed pivot point on the shaft with the ability to pivot about it, and the accelerator has a shaft on which the pinion gear is connected to a ratchet pinion gear, in addition to the braking unit consisting of a disc , fixed on the accelerator shaft and two adjustable braking elements interacting with the disc on both sides and the fact that the vibrator has a fixed disc on the shaft which has recesses arranged in the lower part and a movable blade capable of moving about and rotating about the shaft, the upper portion of which has recesses coinciding with the fixed blade recesses, each of which has, within each shotgun, a spring for pressing discs and a screw adjusting spring compression and locking element engaged between the housing and a moving disk.

The patented simulator has the advantage of introducing a second ratchet mechanism, a second reducer and a second braking assembly to differentiate the load for direct and reverse motion. In this way, muscle antagonists with different degrees of development are trained, e.g. biceps and triceps. Before the workout, they choose a different workout. The spring unit in the load unit, which generates a load for linear motion, also improves the efficiency of training, using the rope as a means of performing motion and exerting additional effects on the muscles, e.g. stretching them after a workout. In addition, the accelerators in the load unit and the gears of the first and second directional movement blocks, which reduce the amount of transmitted motion, enable sensitive load adjustment over a wide range, which improves the ergonomic features of the simulator. Improvements to these features include the small size of the simulator and the ability to create many modifications.

The extension of the simulator functions is achieved by the ability to perform exercises not only in the X, Y but also in the Z plane, due to the fact that the simulator has three block angle locators engaged between the joining unit and the bodies of the first direction of movement. , as well as between the second motion direction block and the rear block housing, which combines both ratchet mechanisms, both accelerators and both braking devices. Fixers allow you to change the position of blocks in space.

The adjustable braking members 46, 47 and 54, 55 select different loads for clockwise and anti-clockwise movement. Muscle antagonists are trained in this mode.

In the second mode, the switch 57, by moving it to position "a" or "c" (Fig. 10), disengages one ratchet mechanism 17 or 20, and actuates the spring assembly 15 by blocking one or more cylinders 33 with the locking element 35. muscles in one-way movement under load. After exercise, the device 1 is automatically restored to its original position by the spring unit 15 and the muscles being trained have a pause.
