Description

The inventive device relates to the field of sports, and in particular to technical means for performing physical exercises aimed, in particular, at developing mobility in the joints. When these exercises are performed, the physiological processes of the formation of various muscle qualities (for example, elasticity, strength, strength, endurance, etc.) are stimulated.

In order to stimulate such physiological processes in modern sports and rehabilitation medicine, simulators are widely used, when using which physical exercises are performed against the background of exposure to muscles of low-frequency mechanical vibration.

Known sports medical simulator for muscle training and prevention of motor disorders, the development of flexibility in the joints, which contains a base made in the form of a frame on which a shock absorber is formed a platform made in the form of a frame with a wooden floor, sheathed in leather and equipped with handrails, and the bottom surface of the platform mounted vibrator of spatial vibrations [1]. Such a device provides intensive directed vibration exposure to the muscles of the whole organism. However, this advantage - the uniform intensity of vibration exposure throughout the body, at the same time determines its disadvantages - the impossibility of differentiated vibration exposure, in particular, to certain parts of the human body and, accordingly, certain joints. In addition, the device is quite bulky and requires a sufficiently large area for installation, which limits its ability to be used as a personal simulator.

A device for vibration therapy of joints is also known, which is used to restore muscle functions and stimulate blood circulation in the joints [2]. The device is made with the possibility of mounting on human limbs through a system of belts and with the possibility of battery life (from built-in batteries). The design of such a device makes it possible to simultaneously generate frontal multidirectional mechanical vibrations, but only due to a very complex mechanical system for converting electrical energy into mechanical vibration energy, which reduces the reliability of the device. In addition, given the rather large dimensions, such a device may not be used for all joints (for example, hands or feet).

Also known are vibratory simulators specially designed for individual parts of the human body. So, in particular, a vibration massage hand trainer is known, which contains a body, a vibrator and massage nozzles in the form of a hemisphere and in the shape of a cone [3]. The simulator is intended for use to stimulate muscle activity and blood circulation of the forearm and wrist joint. The disadvantage of this device is the narrow focus of vibration (only on the muscles of the hand and partly the muscles of the forearm) and the need to use interchangeable nozzles of various shapes.

Also known is a stimulator simulator comprising a generator of low-frequency mechanical vibrations and a support rigidly connected to it in the form of an inverted paperweight with which parts of the human body interact [4]. However, the described device is characterized by two significant disadvantages. Firstly, in it the energy of the vibration generator is expended not only on the vibration of the stimulated part of the body, but also on the vibration of the said support, which has some mass. Secondly, vibrational movements of the stimulated part of the body are possible only in a vertical plane by placing part of the body on a support from above. Oscillatory movements of the stimulated part of the body in the horizontal plane are not provided for by the design of this device, which narrows the circle of stimulated muscle groups. Manufacturers of stimulator simulators are trying to get rid of the second drawback by installing the simulator on a special manipulator, the design of which allows changing the orientation of the simulator in space, giving parts of the body the opportunity to interact with the support not only in horizontal but also in vertical planes. However, with this approach, the simulator design becomes more complicated and more expensive.

The objective of the invention is to provide a device that, while simplifying the design as a whole, would provide a reduction in energy costs for vibration of the support, as well as enable the parts of the human body to interact with the support not only in horizontal and vertical planes, but also in a large number of other spatial positions.

The problem is solved by the proposed device for vibrational effects on the human body, containing a mechanical oscillation generator mounted on the bed, consisting of an electric motor and means for converting electrical energy into mechanical vibration energy, and a means of contact transmission of mechanical vibrations connected to the mechanical oscillation generator to parts of the human body. The problem is solved due to the fact that the means of contact transmission of mechanical vibrations to parts of the human body is made in the form of a rigidly fixed frame, elastically deformable over the entire surface area of the support for parts of the human body, having the form of an incomplete hollow cylinder, and a means of converting electrical energy into energy of mechanical vibrations made in the form of a crank mechanism, the crank of which is rigidly connected to the output shaft of the electric motor, and the connecting rod is pivotally connected to the support for parts of the human body with Oron its inner surface with a reciprocating movement between two extreme positions, wherein the diameter of the support body parts and the rod length so selected

- 1 014922 so that in the middle position of the connecting rod the support for parts of the human body is not subject to deformation, and the longitudinal axis of the connecting rod is located at an angle α> 0 to the transverse axis and at an angle β> 0 to the longitudinal axis of the support for parts of the human body.

In preferred embodiments of the inventive device, the angle α is about 90 °, and the angle β is from 45 to 135 °, preferably 90 °.

Elastic deformation over the entire surface area of the support for parts of the human body can be provided in preferred forms of implementation, in particular due to the fact that the support for parts of the human body is made of sheet material, preferably sheet steel.

The essential features listed above, characterizing the design features of the claimed device, were selected by the authors from a number of technical solutions they found in many years of development and experimentally tested, as ensuring the most effective achievement of the claimed technical result: a) elimination of the part of the electric motor from the total cost of energy that the prototype accounted for the oscillatory movement of the mass of the support in the form of an inverted paperweight (in the inventive device, the mass of the support to compensated by the reaction of the bed rigidly connected to it), b) the absence of the need to use the manipulator to change the orientation of the device in space while significantly simplifying the design and expanding the possible spatial positions of the body part on the support for parts of the human body.

Below, the advantages and advantages of the claimed device for the development of mobility in the joints will be described in more detail on the example of one of the possible preferred, but not limiting forms of implementation with reference to the position of the drawings, which show:

FIG. 1 is a schematic front view of the inventive device;

FIG. 2 is a schematic partial longitudinal sectional view of the device of FIG. one.

In FIG. 1 is a schematic front view, and in FIG. 2 in longitudinal section shows the inventive device for vibrational effects on the human body, containing a mechanical oscillation generator mounted on the frame 1, consisting of an electric motor 2 and means for converting electrical energy into mechanical vibration energy, made in the form of a crank mechanism, the crank 3 of which is rigidly connected with the output shaft 4 of the electric motor 2, and the connecting rod 5 by means of a swivel element 6 is connected with the support 7 for parts of the human body from the side of its inner surface ited 8. The support 7 for the human body parts are rigidly secured to the base 1 has the shape of a hollow cylinder and the partial elastically deformable is formed on the entire area of the support surface for the human body parts, in this example - of thin sheet material, preferably sheet steel. The diameter of the support 7 for parts of the human body and the length of the connecting rod 5 are selected so that in the middle position of the connecting rod 5, marked in FIG. 1 line Θι-Θ ₂ , support 7 for parts of the human body is not subject to deformation. In this position, the support 7 for parts of the human body for greater clarity is depicted by a bold line. In the extreme lower and in the highest upper position, in each case, the support 7 for parts of the human body is depicted by two thin lines and indicated by the positions 9 and 10, respectively. The longitudinal axis of the connecting rod 5 in this example is located at an angle α = 90 ° to the transverse axis and at an angle β = 90 ° to the longitudinal axis 11 of the support 7 for parts of the human body. Arrows A and B in FIG. 1 indicate, respectively, the vertical and horizontal direction of transmission to the support 7 for parts of the human body of mechanical vibrations of maximum amplitude.

The device operates as follows.

When the electric motor 2 is switched off, when the connecting rod 5 is in an intermediate position, the support 7 for parts of the human body is not subject to deformation and has the cross section of the shape of a regular incomplete hollow cylinder, the open ends of which along the height of the cylinder are bent inward and rigidly fixed to the bed 1. To reduce in the following text, the shape of the support 7 for parts of the human body in an intermediate position will be designated as a cylinder.

When connecting the electric motor 2 to the power source (not shown in the drawings), the connecting rod 5, connected by means of the crank 3 to the output shaft 4 of the electric motor 2, performs low-frequency reciprocating movements, in this example, when the angle α = 90 °, in the vertical plane. The mobility of the structure is ensured due to the articulation of the connecting rod 5 with the support 7 for parts of the human body from the side of its inner surface 8, on the one hand, and the rigid connection of the crank 3 with the output shaft 4 of the electric motor 2, on the other hand. Performing low-frequency reciprocating movements, the connecting rod 5 in its highest position, acting on the support 7 for parts of the human body, gives it the shape of a vertically elongated ellipse, indicated in FIG. 1 by 10, and in the lowermost position, the shape of the horizontally elongated ellipse 8, shown in FIG. 1 by 9 (for abbreviation in the following text, the shape of the support 7 for parts of the human body in extreme positions will be denoted as an ellipse). At the same time, the part of the human body interacting with the upper part of the support 7 for parts of the human body, for example, the foot, the foot of which is located on the upper part of the support 7 for parts of the human body, will perform vertical oscillatory movements indicated by arrows A. At the same time, when placing the body part a person on a support 7 for parts of the body in the area of its lateral part, for example

- 2 014922 of the right lateral part, leads to horizontal oscillatory movements of the part of the human body in the direction of arrows B. Moreover, when the location of the part of the human body is shifted between strictly vertical and strictly horizontal positions, the part of the human body will also be exposed to mechanical vibrations. Thus, there is no need to change the orientation of the device during the transition from stimulation of a part of a human body in a vertical plane to its stimulation in a horizontal plane, as well as the exact positioning of a part of a human body on a support 7 for parts of a human body in a strictly vertical or strictly horizontal position. It is enough to only move a part of the human body from the upper zone of the support 7 for parts of the human body to the lateral zone of the support 7 for parts of the human body.

In the example described above, the angles α and β have values equal to 90 °, which ensures the most uniform distribution of deformations over the surface of the support 7 for parts of the human body. In other forms of implementation, the swivel 6 can be displaced on the inner surface 8 of the support 7 for parts of the human body both in relation to the transverse axis 11 of the support 7 for parts of the human body (angle α) and in the direction of its longitudinal axis 12 (angle β). In these cases, the distribution of deformations over the surface of the support 7 for parts of the human body will have a more complex form.

In the inventive device for vibrational impact on the human body due to the features of its design, the energy of the electric motor 2 is spent only on overcoming the elastic deformation forces of the support 7 for parts of the human body, taking under the influence of the reciprocating connecting rod 5 the shape between the ellipse 9 and the ellipse 10 with the transition through the form cylinder 7. With this operation of the electric motor 2, partial recovery of electrical energy occurs, when the energy of elastic deformation of the support 7 for parts of the human body p turns into electric and returns to a power line. The energy costs for oscillatory movements of the mass of the support 7 for parts of the human body are minimized, since the latter is rigidly connected to the frame 1 and, in addition, has a small mass due to its implementation from sheet material, preferably sheet steel.
