Description

The invention relates to a class of simulators designed for the development of major muscle groups, and can be used both for training the general state of health of trainees, for special training of athletes, and in medicine as a means of rehabilitation in the post-traumatic period.

Known exercise bike, consisting of front and rear supports connected to the base in the form of tubes, a loading unit with pedals fixed to the base, racks, the first of them has a rod inserted into it, and a rod with a seat is fixed in the second rack. The load node consists of two chains interacting with each other, a drum with a brake band, each chain having its own axis connected to the pedals, and the force of interaction with the pedals is regulated by changing the force of the brake band (US Patent No. 4,602,781, IPC A 63 V 21/00).

The disadvantage of this device is that the load node of the exercise bike does not have the ability to change peak loads in the rotation cycle, which reduces the training effect, the lack of regulation of the loads separately on the right and left lower limbs.

Known exercise bike containing front and rear supports connected by a base with load nodes, racks with a rod and a rod, elongated spring-loaded pedals fixed movably in the axes of the base. The loading unit is the first axis on which the connecting rods with pedals and the drive sprocket are placed, the driven sprocket and the drum with brake band are located on the second axis (US Patent No. 5299992, IPC A 63 V 22/00).

However, the load node of this simulator also does not provide the possibility of changing the nature of the load in various positions of the pedal during the cycle of their rotation.

Known exercise bike containing front and rear supports connected by a base with load nodes, racks with a rod and a rod, elongated spring-loaded pedals fixed movably in the axes of the base. The rod and rod are movable vertically and horizontally, one rack is rigidly connected to the carriage at the base, the second is rotatable and fixed rigidly to one of the load nodes, the steel cone of which is rigidly connected to the cheek, base and cone of wear-resistant material rigidly fixed in it, while the sleeve is spring loaded and limited in axial movement by a ring with a nut. Each of the load nodes contains a conical sleeve, a conical roller with pedals, a nut and a ring, and the conical roller is fixed with a nut and ring with the possibility of rotation in the conical sleeve (RF Patent No. 2211717, IPC A 63 V 22/06, A 63 V 22/00 )

However, the load node of this simulator also does not provide the possibility of changing the nature of the load in various positions of the pedal during the cycle of their rotation.

Closest to the claimed is an exercise bike containing front and rear supports connected by a base with load nodes, racks, pedals installed in the axis of the base. One of the racks is rigidly connected to the carriage at the base with the possibility of horizontal rearrangement, and the second rack is made rotatable and rigidly connected to the sleeve of the loading device, mounted movably with a roller fixed for rotation in the bushings of the cheeks, while the second sleeve and bushings are rigidly fixed to the roller installed with the possibility of covering them with tapes in several turns, one end of which is rigidly connected to the cheeks, and the second end is spring-loaded and secured with the possibility of simultaneous tension and fixing and tapes for specific loads, and the pedals are interconnected by an elastic element covering a spring-loaded load roller (RF Patent No. 2195354, IPC A 63 V 22/06, A 63 V 22/02).

This design of the exercise bike, like previous analogues, allows you to change the value of the load on the muscles of the trainee. However, the load node of this simulator also does not provide the possibility of changing the nature of the load in various positions of the pedal during the cycle of their rotation and the magnitude of the force exerted on each lower limb of the trainee.

The objective of the invention is to expand the functionality of the exercise bike by changing the nature of the impact on the muscles of the trainee by increasing the number of peak loads per cycle of pedaling, shifting the position of the peak loads along the length of the cycle, and also the ability to change the magnitude of the force exerted on the left and right limbs of the trainee.

The problem is solved in that in an exercise bike containing a base with an axis on which the racks are fixed, pedals are fixed to the axis by means of connecting rods, a load node including elastic elements, according to the invention, the load node contains at least two washer-shaped elements with a variable profile , each of which is made with the possibility of changing the position around the axis to change the nature of the load, and at least two load elements mounted on rods, each of which is made in the form of a split married in a cylindrical body of the ball, interacting, on the one hand, with a washer-shaped element, on the other hand, with an elastic element located in the body, while the body is equipped with stops for the ball, and its end part is configured to control the force of the elastic element.

In addition, the racks and supports can be made with the possibility of rotation around the axis of the base and provided with fasteners for fixing to the washer-like element. To ensure the rotation of the uprights and the base, the base axis is provided with bushings. The inner surface of the cylindrical body of the load element is threaded to move its end surface when the force of the elastic element changes. The load element is provided with a liner between the ball and the elastic element.

The invention is illustrated by drawings, where figure 1 shows a General view of an exercise bike, figure 2 is a section aa of an exercise bike.

The positions in the drawing indicate:

1 - base

2,3 - racks,

22 - fasteners.

The exercise bike consists of a base 1, racks 2 and 3. A rod 4 with a seat 5 is fixed on a rack 2, and a rod 6 with handles 7 is fixed on a rack 3. The rod 4 and rod 6 are arranged to swap them in height. The base 1 has an axis 8, on which the load node is fixed. The load node includes at least two washer-shaped elements with a variable profile 9, at least two load elements 10 mounted on the connecting rods 12. A particular option for fixing the load elements on the connecting rods is to place these elements in the inner cylindrical cavity of the pedals 11. The profile of the washer-shaped element 9 is selected depending on the objectives of the workout. Element 9 is rigidly attached with fasteners 22 to the base 1 and the racks 2, 3.

The load element 10 is a cylindrical body 13 having an end surface 15, which is arranged to move along the thread 20 using the handle 16. On the opposite side of the end surface, the body is equipped with stops 17 for a ball 19 located in its cavity in contact with the washer-like element 9 The elastic element 14 and the insert 18 between the end surface and the ball are placed in the housing. T.O. the movement of the end surface of the cylindrical body 15 provides the ability to control the force of the elastic element 14. To ensure the required position of the saddle 5, the handles 7 in the simulator bushings 21 are used, which provide rotation by the required amount. The selected position of the saddle and handles is fixed by means of a washer-like element using fasteners 22.

The device operates as follows.

Before starting work, set the height of the seat 5 and the handle 7 using the rod 4 and the rod 6, respectively, and horizontally the distance between the seat 5 and the handles 7, changing the position of the posts 2 and 3 by turning them around the axis of the base 8 with subsequent fixing to the washer-like element 9 by fasteners 22. Depending on the training tasks, the nature and magnitude of the load is determined, which is determined by the changing profile of the washer-like element 9 and the force of the spring 14 of the load element 10. The nature of the load can also be changed not by turning the washer-like element around the axis of the base 8, which allows you to change the position of the peak loads in any of I, II, III, IV quarters in the cycle of pedaling. The force of the elastic element 14 is regulated by the handle 16 of the load element 10.

When the pedals 11 rotate, the ball 19 begins to interact with the washer-like element 9, thus providing an impact on the elastic element 14 and, accordingly, on the muscles of the trainee.

This device allows you to change the magnitude and nature of the load separately for both the right and left limbs of the trainees due to the possibility of installing washer-like elements with different profiles on different racks and the base to ensure the corresponding load. This allows you to significantly accelerate the rehabilitation process in the post-traumatic period.
