Description

A device for regulating the load on a sports simulator relates to the field of sports and can be used as an integrated module as part of already existing sports simulators, in which the load must be adjusted, or used in the development of new designs of sports simulators. The proposed device can be used on sports simulators operated on outdoor playgrounds.

The known design of the flywheel contains a hollow body mounted on the shaft, inside which there is a bulk material (steel balls or cast iron chips), while the flywheel hub is made of magnetic material, and the hollow body with a rim of a material that does not have magnetic properties, and the bulk material interacts with a magnet (see patent for IZ No. 2439394, class F16F 15/31)).

The known design of the flywheel with easy start, containing a hollow rim filled with filling fluid, in the internal volume of which partitions (curtains) with holes, fitted with valves, are inclined (see patent for IZ No. 2327910, cl. F16F 15/31).

The disadvantage of both analogs is the inability to smoothly adjust the torque on the flywheel shaft during its operation and when a certain angular velocity is reached in a given range.

The closest to the proposed technical solution to the technical essence, in my opinion, is a “muscle training device” (prototype, patent for PM No. 107949, CL А63В 23/00), which contains elements hinged on the body (base) of the sports simulator transmission of torque, plumbs, made in the form of a hollow drum, the internal cavity of which is filled with the surrounding component. Load control is carried out by adding or subtracting the enclosing component through the window.

One of the drawbacks of the prototype is that the load control on the elements proposed by the author for applying force by adding or dropping the surrounding component through the drum window does not allow changing the load value during training on a sports simulator (you can only change it when the training process stops).

Another disadvantage is that the pendulum design of the prototype limits the acquisition of an arsenal of devices aimed at training and developing the muscles of users.

In addition, the known device has a large inertia due to the fact that the mass of the surrounding component is at a great distance from its geometric axis of swing.

These deficiencies are eliminated in the proposed design of the device for controlling the load on the sports simulator.

In the proposed device for regulating the load on a sports simulator containing a plumb, made in the form of a hollow drum, inside which is placed a surrounding component, and elements for transmitting torque, which are movably mounted on the corresponding section of the body of the sports simulator, ACCORDING TO THE TECHNICAL SOLUTION, the device is additionally equipped with a sleeve, installed on the element to transmit torque. The drum is rigidly fixed on one side to the element for transmitting the torque, and the other side is movably connected to the sleeve, the drum is additionally equipped with a cutter and a lever fixed to the sleeve. The lever is located on the outside of the drum, and the cutter is installed with a minimum gap relative to the internal surfaces of the drum.

Besides:

- the device further comprises a fixing device fixed on the body of the sports simulator.

- The number of cutters in the device may be more than one.

- internal surfaces of the drum can be made with different stiffness and roughness.

Common features of the proposed technical solution and prototype are:

- the presence of the body (base) of a sports simulator

- the presence of a hollow drum

- the presence of elements for the transmission of torque, movably installed on the corresponding part of the body (base) of a sports simulator

Distinctive essential features are:

- the presence of an additional sleeve mounted on the element for transmitting torque.

- fastening the drum with one side rigidly on the element for transmitting torque, and the other side of the movable connection with the sleeve,

- additional supply of the drum mounted on the sleeve with a cut-off and lever,

- the location of the lever on the outer side of the drum,

- the establishment of the cutter with a minimum gap relative to the internal surfaces of the drum.

The presence of these significant distinctive features ensures the compliance of the proposed technical solution to the condition of patentability "novelty" under the current legislation.

The selection from the list of analogues of the prototype ensured the identification of a set of distinctive features of the claimed device that are significant in relation to the technical results.

Comparison of the proposed invention, not only with the prototype, but also with other technical solutions in related areas, showed that the latter do not contain signs that are similar to the features that distinguish the claimed technical solution from the prototype.

This allows to make a conclusion about the compliance of the proposed technical solution to the condition of patentability "inventive step" under the current legislation.

The objective of the proposed invention is to minimize the inertia of the movable elements of the proposed device, the elimination of an arbitrary load change during exercise, the ability to change the load value independently by the user during training.

The technical result, which cannot be achieved in any of the presented analogues, including the prototype, provides:

- load control independently by the user on a sports simulator without interrupting the training process with minimum inertia of the moving elements of the device;

- expansion of the arsenal of technical tools that implement their purpose in the form of a technical solution “Device for controlling the load on a sports simulator”.

The technical result specified above is achieved due to the fact that the device for regulating the load on the sports simulator, containing a plumb, made in the form of a hollow drum, inside which is placed the enclosing component, made, for example, in the form of steel balls or cast iron chips, or any other bulk material, elements for transmitting torque, movably mounted on the corresponding section of the body of the sports simulator, according to the technical solution, the device is additionally equipped with a sleeve, fixed on the element for transmitting torque, one side rigidly fixed on the element for transmitting torque, and the other side is movably connected to the sleeve, the drum is additionally equipped with a cutter and lever fixed to the sleeve, the lever is located on the outside of the drum, and the cutter is installed with minimum gaps relative to the internal surfaces of the drum.

And also due to the fact that the device additionally contains a fixing device fixed on the body of the sports simulator, the number of cutters can be more than one, and the inner surfaces of the drum can be made with different stiffness and roughness.

Introduction of an additional sleeve mounted on the element for transmitting torque and fixed on the cutter and lever bushing, rigid connection of the drum with one side to the element for transmitting torque and the other side movable connection with the sleeve, placing the lever on the outside of the drum, and installing the cutter with a minimum clearance relative to the internal surfaces of the drum, allowed to provide load control to the trainees on the sports simulator without interrupting the training process with a mini the maximum inertia of the moving elements of the device, and in expanding the arsenal of technical tools that realize their purpose in the form of the technical solution “Device for controlling the load on a sports simulator”.

FIG. 4 shows an illustration of the z. P. 3 formulas

A device for regulating the load on a sports simulator includes: body 1 (see Fig. 1) of a sports simulator, a hollow drum 2 made with a solid surface, rigidly fixed on one side on an element for transmitting torque 3, made, for example, in the form of a shaft, installed in the housing 1 of the sports simulator, and the other side of the drum 2 (see Fig. 2) is movably connected to the sleeve 4 mounted on the element for transmitting torque 3. The cutter 5 is made, for example, in the form of a plate and installed with a minimum clearance (on the devil, not denoted.) relative to the internal surfaces (on the devil, not descriptive). drum 2. The lever 6 is fixed on the sleeve 4 on the outer side of the drum 2. The surrounding component 7 is, for example, metal balls or cast iron, or any other bulk material. The locking mechanism (to hell, not denoted.) Is fixed on the body 1 of the sports simulator. The elements 8 for transferring the load are fixed at the respective ends on the element 3 for the transmission of torque.

A device for controlling the load on a sports simulator is operated as follows:

A user who wants to use a sports simulator equipped with the proposed device, using elements 8 for transferring the load (see Fig. 2), made, for example, in the form of levers with handles (see Fig. 2) or pedals 9 and 10 (or other known in engineering devices for transmitting torque from the shaft to the executive mechanisms of sports simulators, for example, the ellipsoid mechanism of the exercise bike, the belt or chain transmission on the bike pedals, etc.) rotates the drum 2 through an element for transmitting torque 3. At a certain speed of rotation of the drum 2, the surrounding elements 7 (see Fig. 3) under the action of centrifugal force and, as a consequence of the friction force, rise in the drum 2 in the direction of the arrow and, encountering an obstacle in the form of a cutter 5, begin to be reflected from it and fall down under the action of its own weight (the movement of elements of the surrounding element 7 occurs along the trajectory indicated by a thin line with arrows, see FIG. 3). This creates a certain load (torque M cr.) On the element for transmitting torque 3, which the user can adjust during the workout without stopping the drum 2 using the fixation mechanism (not drawn in the drawing) by changing the angle of inclination “alpha” a cutter 5 (see Fig. 3) by means of the lever 6 (see Fig. 2) with subsequent fixation. (As a locking mechanism, any known device can be used, for example, a screw mechanism).

The presence of the maximum gap between the cutter 5 and the inner surfaces of the drum 2 prevents friction between these surfaces and prevents the enclosing element 7 from penetrating through the gap (not shown in the drawing).

This device has the minimum necessary inertia, which is necessary to ensure smooth operation of the elements for transferring the load 8 and is determined only by the mass of the peripheral part of the drum casing 2 (due to the fact that the encircling component 7 does not rotate with the drum 2 because of its movement cut-off 5).

The user himself sets the required load by turning the lever 6 and locking the cut-off 5 in the required position using a locking mechanism (not shown in the drawing) installed on the body 1 of the sports simulator in a place convenient for the user.

In the proposed device, the cutters 5 can be installed more than one, for example, two (see Fig. 4). In this case, the second cutter 5A (lower in the drawing), is an inclined plane along which a part of the encircling component 7 rolls, creating additional pressure on the internal cavity of the drum 2, thereby increasing the torque (M cr.). Thus, the total load on the sports simulator increases.

In the proposed device, the inner surface of the drum 2 can be made with different stiffness and roughness, which also contributes to the change in the total load on the sports simulator.

The internal cavity of the drum 2 once and partially filled with the surrounding component 7. A single loading of the drum 2 is carried out in the process of its manufacture.

Due to the implementation of the proposed device in the form of a non-separable module with a solid surface, a rigid structure that does not require maintenance, the anti-vandal protection is achieved, which allows the proposed device to be used on various sports simulators, which require load control, with operation in outdoor conditions, and The speed of load control makes simulators equipped with the proposed device available for mass use.

The proposed invention can be repeatedly manufactured on the basis of mass-produced domestic and foreign industry materials using modern mastered technology and can be used to train the main muscle groups of adolescents and adults both in sports halls and on street sports grounds, which allows to conclude that the proposed invention the criterion of "industrial applicability".
