Description

The invention relates to sports and gaming simulators and can be used for muscle training and special training (in traction, coordination of motor actions, including computer games).

A device is known - “power joystick” [1], which has almost all the elements of the electrical circuit of a conventional “joystick”, but the design itself is designed to exert considerable effort on the lever of the “game rod”, made to change the values of the resistance, for which spiral springs are used springs fixed on a massive base. Changing the values of resistance to the efforts of the student is ensured both by changing the length of the lever (the working part of the "game rod"), and by controlling the "stiffness" of the spiral spring.

The advantage of this technical solution is that it controls the movements of the figures on the screen of the monitor (display), connected to the computer by means of this power device, which fully performs the functions of the “joystick” when dosed forces and sizes are applied to it.

The disadvantage of this device is that it is not possible to smoothly adjust the dosed load resistance, therefore, removable handles are used that provide different conditions for gripping and applying force, and, in addition, the greatest force is manifested when the “game rod” is maximally withdrawn from the equilibrium position.

Known technical solution - “Device for training muscles” [2], containing a game rod made with the possibility of changing the magnitude of the resistance provided by changing the length of the lever - the working part of the game rod, several modifications of the removable handles for attaching to one end of the game rod, each of which is equipped with buttons, an electric cable for connecting to the system unit of a personal computer and a base for attaching the device to it using fasteners optical “mouse” that controls the position of the cursor on the computer monitor screen depending on the movement of the game rod, the keys of which are connected electrically with the buttons of each handle, while the other end of the game rod is made in the form of a ball placed in a glass, forming an environment of adjustable friction for ball, and the controlled friction medium is provided with the help of a tightening unit and elements rubbing against the ball located in the upper and lower parts of the glass, the tightening unit includes an upper the bottom plate, the lower fixed plate and the rubber damper plate, in the upper rubbing element, in the upper movable plate and the damper rubber plate, as well as the lower rubbing element and the fixed plate are made circular through holes for moving the game rod, and the optical “mouse” scans the surface of the ball through the holes in the fixed plate and the lower rubbing element.

The disadvantage of this device is the narrow adjustment range provided by the tightening mechanical unit, and the associated difficulty in setting the required value of the dosed resistance provided.

The closest technical solution [3], selected as a prototype, is a “Device for training muscles” containing a “game rod” made with the possibility of changing the value of the resistance provided by changing the length of the working part of the “game rod”, several modifications of the handles for attaching to one end of the "game rod", each of which is equipped with buttons, an electric cable for connecting to the system unit of a personal computer, a base for mounting on it triads using fasteners, an optical “mouse” that controls the cursor position on the personal computer monitor screen depending on the movement of the “game rod”, the keys of which are electrically connected to the buttons of the connected handle, while the other end of the “game rod” is made in the form of a ball placed in a glass, forming an environment of controlled friction for the ball, provided by means of a tightening unit and rubbing against the ball elements located in the upper and lower parts of the glass, the lower of them is placed on a fixed plate and the ball is supported on it, and the upper friction element is pressed against the ball by means of the first movable plate by pull rods connecting the first movable plate to the second movable plate, and in the upper friction element and the first movable plate, as well as in the lower through the rubbing element and the lower fixed plate, through circular holes are made, the first for moving the “game rod”, and the second for scanning the surface of the ball with an optical “mouse”, attached from the bottom to the fixed plate, the tightening unit in it, along with the known ones, also includes an additional n conical springs inserted on n traction rods and located between the first movable plate and the upper friction element on the summing plate, the rod fixed in the second movable plate equidistant from mounting traction rods in it, located below the optical "mouse", a lever mounted on corners mounted on the inner side wall of the glass, and connected at one end to the rod, and the other their end through a slot in the wall of the glass and the connecting bar - with a traction pin having flats along its entire length and passing through the guide and traction device, which includes a guide and traction "wing nut", and which is mounted on the outer side surface of the glass in its upper part, in addition, a circular hole is made in the summing plate, and friction between the ball and the rubbing element is increased in the upper half of said ball.

The disadvantages of this device are the following:

- use of the nth (four or three) number of identical conical springs;

- not every optical mouse is suitable for use in this device according to its overall dimensions and the size of the gap between the ball and the mouse;

- difficulties with its replacement;

- the use of studs with a flat along the entire length and, as a result, the movement of this studs in the longitudinal direction by means of a wing nut.

The problem solved by this proposed invention is: the use of a single cone-shaped spring that provides uniform resistance to the game rod in the entire sector of its movement, the use of a miniature optical mouse and the choice of its gap with respect to the ball, as well as removing it into the side window, using a mechanical "screw-nut" systems in the task of resistance to the game rod using a mini-turn.

An optical mouse 28 is installed near the fixed plate 9, scanning the surface of the ball 4, for which a window 29 is cut out in the side wall of the cup 5, and on the opposite side of the cup 5 two oblong holes for guides and securing the miniature holder 30 of the optical mouse 28. Electric keys are made from the keys of the optical mouse 28, ending with buttons 31 and 32, respectively, from the right and left keys. The optical mouse 28 is also connected to the system unit of a personal computer using an electric cable 33. In the upper 6 rubbing element, the upper 8 movable plate and the summing plate 16, through circular holes are made to move the game rod 1. In the lower 7 rubbing element and the lower 9 stationary plate through holes are also made for scanning the surface of the ball 4. The device is mounted on the base 34 using, for example, screws or screws 35, 36, 37 and 38. And the stud 22 in the working position only performs a rotational movement, which is achieved by a screw 39.

Moving the game rod 1 from itself to itself, move the cursor in the vertical plane of the display screen. Moving the game rod 1 to the left, and then to the right, move the cursor in the horizontal plane of the screen, respectively. Thus, moving the game rod 1 in space, move the cursor on the display screen, thereby setting the physical load on the muscles of the shoulder girdle and partially on the back muscles.

In the upper 41 rubbing element, the upper 43 of the movable plate and the summing plate 46, through circular holes are made to move the game rod 1. In the lower 42 rubbing element and the lower 44 of the stationary plate through circular holes were made to scan the surface of the ball 4. The device is mounted on the base 34 using, for example, screws or screws 35, 36, 37 and 38. The stud 22 in the operating position only rotates positive movement, which is achieved by screw 39.

Work with the device as follows.

Using screws or screws 35, 36, 37 and 38, fix the device on the base 34. Using the wheel 24, set the required resistance of the game rod 1.

If a solid body moves relative to another solid body, and their surfaces are in contact, then a force arises that impedes this movement. This force is called the friction force. It is explained by the roughness of the rubbing surfaces, as well as by the forces of molecular interaction. If there is no liquid layer between the surfaces of contacting solids, then this friction is called dry. Dry friction is divided by the nature of the movement into sliding friction (one body glides along the surface of another) and rolling friction (one body rolls along the surface of another). We will be interested in dry sliding friction.

The magnitude of the friction force (F _Tr ) of sliding depends on the nature and quality of processing of the contacting surfaces, as well as on the magnitude of the force pressing the friction surfaces (normal pressure force F _n.d. ), and does not depend on the size of the contact surface:

;

;

where k is the coefficient of friction, which depends on the nature and quality of the processing of rubbing surfaces and insignificantly on the speed of movement (this dependence is usually neglected).

Thus, the force of normal pressure F _n.d. found by the formula:

.

.

On the other hand, under the influence of external forces, every solid body changes its shape - it is deformed. A deformation that disappears with the cessation of the force is called elastic. With elastic deformation of the body, internal elastic forces arise, which tend to return the body to its original shape. The magnitude of these forces is proportional to the deformation of the body. The resulting elongation or shortening of the sample (Δl) under the action of an external force (F) is proportional to the magnitude of the acting force, the initial length l and inversely proportional to the cross-sectional area (S):

- коэффициент пропорциональности.Where

- coefficient of proportionality.

Formula (3) expresses Hooke's law.

The value of E is called the elastic modulus of the first kind or Young's modulus and characterizes the elastic properties of the material.

In our case, F _n.d. = F, i.e. substituting all quantities into formula (3), we obtain the shortening of the spring (Δl) (since it works for compression). This movement is increased by the lever, in which the fulcrum is between the points of application of the forces acting on it, i.e.

,

,

where F _у - balancing force created by the screw,

and - the second shoulder of the lever.

In addition, in the absence of friction in the screw pair, F _y acting along the axis of the screw is balanced by the force F ₃ applied to the wheel 24 directed tangentially to the circle outlined by this wheel and equal to

,

,

where h is the pitch of the screw, R is the radius of the circle outlined by the “wing nut”.

Using formulas (1) - (5), one can calculate the physical parameters of the claimed device, as well as be guided in the choice of material and surface treatment of the contacting bodies, thus adjusting the resistance value.

In the proposed invention, a number of new technical solutions are applied, namely: a lever-power system based on one spring and four traction rods, a new mini-winch construction based on the “screw-nut” principle with a rotating pin, without its longitudinal movement, and a longitudinally moving nut without it rotation, as well as the articulation of the lever-power system with a mini-turn.

Consider one of the possible designs of the articulation (figure 5, 6, 7) and its operation in the device 1. It contains a stud 22, made able to rotate without longitudinal movement, and a nut 21 of rectangular shape with the ability to move in the longitudinal direction without rotation and is equipped with two cylindrical clamps 51 and 52 fixed in it by short studs 53 and 54. A nut 21 with a screwed-in stud 22 is placed in the vertical clearance of the lever 18, in which the cylindrical clamps 51 and 52 are installed in the horizontal gaps of the specified lever 18. D For durability, cover 27 closes four protrusions of this lever (Figs. 5, 6, 7).

The articulation works as follows.

By rotating the wheel 24 (see, for example, FIG. 1), the nut 21 sets the load on the game rod 1 by acting on the ball 4 through the lever 18, the connecting bar 20, the rod 17, the second movable bar 10, four traction rods 11, 12, 13 and 14, the second movable plate 8, the spring 15, the summing plate 16 and the rubbing elements 6, 7. The screw 39 fixes the rotation of the wheel 24, even if there is a quick load shedding, and the cylindrical clamps 51 and 52 are used to select the radius of movement of the lever 18 in articulation.

Compared with the prototype, the proposed device exhibits additional properties that made it possible to simplify the spring power system, use a miniature optical mouse, solve the problem of the gap between the surface of the ball and the optical mouse and remove it from the device without disassembling it, and perform the tightening assembly in this way so that during operation of the device, the pin does not extend beyond its limits, while maintaining a lightweight task of the required value of the provided dosed resistance with a uniform resistance to the game rod within the entire specified sector of its movement and smooth adjustment of the value of this resistance.
