Rotary action device for the formation of an adjustable load on a sports simulator

A rotary action device for generating an adjustable load on a sports simulator refers to sports equipment and can be used to create a load in exercise machines that use rotary motion to create a load - exercise bikes, steppers, ellipsoids, treadmills, etc.

Known is the construction of a device for training muscles, which contains pivotally mounted on the body (base) of a sports simulator elements for transmitting torque and plumb bob, made in the form of a hollow drum, the inner cavity of which is filled with loading material. Load regulation is carried out by adding or subtracting the loading material through the window (RF patent for utility model N 107949, A63B 23/00).

The disadvantages of the known device are low vandal resistance and ergonomics of use in open areas associated with the need to provide users with free access to the loading material located inside the simulator, the availability of auxiliary devices for loading and unloading the loading material and the presence of a reserve of loading material close to the simulator in free access, which creates a high probability of loss and deterioration of the loading material due to the effects of wind and precipitation, as well as damage to the simulator itself in case of loading wet loading material. Also, the disadvantage of the known device is the impossibility of its use in the mode of unidirectional movement, which does not allow using it as a load for a number of exercises. The known design of a device for training muscles, containing a rotor made in the form of a hollow drum, the inner cavity of which is filled with a loading material, and elements for transmitting torque, attached to the rotor by means of pins coaxial to the rotor (see RF patent for utility model JST "188300, А63В 21/00).

The disadvantage of the known device is the impossibility of changing the load specified in the manufacture of the simulator.

Known design of an exercise bike, containing a support, a supporting handlebar mounted with the possibility of angular displacement, an adjustable brake means with a brake disc, a saddle, a telescopic rack, an axis of rotation of the pedals of the pedal mechanism, characterized in that the support is made in the form of a frame on which it is installed with using a telescopic rack, a saddle, on the same rack there is an axis of rotation of the pedals, on which the rear wheel is equipped with a freewheel, the steering wheel is mounted on the frame by means of a steering wheel extension, the exercise bike is also equipped with a connecting rod, the upper axis of which is hinged on the steering wheel, with the lower axis of the connecting rod is pivotally and eccentrically mounted on a wheel equipped with a freewheel and mounted on the frame with the possibility of rotation, and this wheel is connected by means of a chain transmission with a brake disc mounted for rotation on the frame and connected, in turn, with a chain transmission - whose with the rear wheel (see RF patent for invention JT “23 18671, A63B 23/04).

The disadvantage of the known design is the use of chain drives for the transmission of torque, which require frequent maintenance and are vulnerable to the effects of precipitation and dust, as well as the use of a friction brake mechanism for the formation and regulation of the load, which in open sports grounds will entail rapid wear of the simulator and will require frequent maintenance to keep it in good working order. Known is a bicycle gear shifting device comprising a frame, a driving and driven sprockets with a chain located between them, and a gear shifting mechanism with a cable, characterized in that it is additionally equipped with a lever, a rod and a spring, while the lever is one the end is pivotally connected to the bicycle frame and equipped with a retainer, and its other end is free and located on a chain, the rod is pivotally connected at one end to the lever, and the other is rigidly connected to the cable of the gear shifting mechanism, the spring is fixed between the lever and the frame ( see RF patent for invention N ° 2252891, B63M 9/06).

The known device solves the problem of changing the force on the leading sprocket, which can be used to create an adjustable load on an exercise bike using any device for weights that creates a constant load - for example, as in the above-discussed RF patent for utility model No. 188300. However, this device for use in exercise bikes for open areas also has a significant disadvantage in the presence of chain drives with a shifting mechanism, which are complex structural elements open to external influences, vulnerable to rainfall, pollution and vandalism.

It is also known a device for a multifunctional simulator containing a platform, an electromagnetic loader attached to it, enclosed in a housing, a drive element and a holder, characterized in that it is mounted on the electromagnetic loader body with the possibility of rearrangement around the circumference of the loader body and fixation on it a deflecting device through which a drive element is passed, made in the form of a cable with the ends stored in the loader and on the holder, moreover, a pedal carriage is mounted in the middle part of the guide, on which a pair of adjustable connecting rods are installed, located on its axis at an angle of 180 or 360o relative to each other, on which the holders are fixed, made in the form of pedals with removable foot pads and toe clips (see RF patent for invention JST ° 2143938, А63В 21/00).

Although this device allows varying the load on the trainee in a wide range, it is unsuitable for use as a simulator for outdoor playgrounds, since it needs power supply from an external source, and is not only vulnerable to precipitation, dust and vandalism, but it can also pose a danger to trainees in the event of a breach of electrical insulation or the load management system.

The closest analogue to the claimed device is a rotary action device for generating an adjustable load on a sports simulator, containing rotors made in the form of hollow drums, inside which a loading material is placed, elements for transmitting torque installed on the corresponding section of the body a sports simulator, and a sleeve mounted on the element for transmitting torque, the drum being rigidly fixed on one side to the element for transmitting torque, and on the other side movably connected to the sleeve and additionally equipped with a cutter and a lever attached to the sleeve; the lever is located on the outer side of the drum, and the cutter is installed with minimal clearances relative to the inner surfaces of the drum; the device additionally contains a fixing device fixed on the body of the sports simulator, there can be more than one cut-off devices, and the inner surfaces of the drum can be made with different rigidity and roughness (see RF patent for invention N22688388, А63В 21/00).

The disadvantage of the known device is a narrow range of changes in the load, in general, a given amount of loading material, viscosity of the loading material, roughness and stiffness of internal surfaces. of the drum, and when the cutters change the range of movement of the loading material, it changes slightly.

The basis of the invention is the task of creating such a device of rotational action for the formation of an adjustable load on a sports simulator, which will ensure the use of the simulator by those engaged in different levels of physical data, which requires at least five-fold range of load change, and the device must be suitable for use in open areas - that is, resistant to precipitation, pollution, temperature extremes and moderate vandalism, does not require external power supply, does not contain friction linings and other wearing and vulnerable elements, which requires the formation of an adjustable unidirectional load without the use of power supply and friction elements - due to the movement of the mass of the load material with its constant amount inside the simulator and without interaction with the external environment.

The problem is solved by the fact that in the inventive device of rotational action for the formation of an adjustable load on a sports simulator containing a rotor installed with the possibility of rotation, elements for converting the effort of the rotor engaged in rotation and loading material located in a closed volume with the possibility interaction with the rotor, according to the invention, the rotor is located inside the casing, made in the form of a hollow box and partially filled with loading material, and the casing is installed with the possibility of displacement relative to the stationary support and equipped with devices for adjusting and fixing the position of the casing relative to stationary support.

In this case, the casing can be installed with the possibility of linear displacement with a vertical component, or it can be installed with the possibility of rotation relative to the stationary support and have a cross-section a plane of rotation other than a circle centered on the axis of rotation. In this case, the casing can be made in the form of a cylindrical pipe with side walls, installed with an eccentricity with respect to the rotor, and installed with the ability to rotate both in the plane of rotation of the rotor and at an angle to it, and the load material can be itself as a free-flowing body and a liquid. Inside the casing, guides for the loading material can be arranged, which are rotatably mounted relative to the casing. In addition, inside the rotor, a load material cutter can be located, which is mounted so that it can rotate relative to the rotor and cannot rotate with respect to the casing during the rotation of the rotor. In this case, the cutter for the loading material can be installed with the possibility of rotation and fixation in various positions relative to the casing.

Also, the casing can be made with the possibility of blocking with a rotor and continuous rotation relative to the stationary support.

Such an embodiment of the claimed invention makes it possible to regulate the force of rotation of the rotor over a wide range, varying the proportion of the load material moved during rotation in the range from a force close to zero, when the resistance to rotation is formed only due to the inertia of the rotor and friction in the drives of the simulator, up to the entire volume ...

The elements for converting the effort of the exerciser into rotation of the rotor, depending on the type of simulator in which the device of rotational action is used to generate an adjustable load, and its design, can be levers with pedals in the case of an exercise bike, other types of crank connecting rod mechanisms for converting movements on steppers and ellipsoids, as well as gear, chain, friction and other known devices. A feature characterizing the performance of an outdoor simulator with a loading material in the form of a loose body or liquid to create a load during unidirectional movement, which allows during operation to place inside the simulator rotor with the possibility of interacting with the rotor a different amount of loading material while its total amount remains unchanged inside the simulator, it was not found in the known technical solutions.

The feature characterizing the performance of an outdoor exercise machine with a loading material, containing a casing and a rotor separate from each other, has not been found in the known technical solutions.

A feature characterizing the performance of an outdoor exercise machine with a casing installed with the ability to rotate relative to a stationary support coaxially to the rotor, while the center of symmetry of the casing is displaced relative to the axis of its rotation, which ensures the placement of different amounts of loading material inside the rotor, in the known technical solutions is not found ...

A feature characterizing the performance of an outdoor exercise machine with a loading material containing a casing and a rotor with a common axis of rotation, separate from each other, in which the casing and the rotor can be fixed relative to each other, has not been found in the known technical solutions.

Based on this, it can be concluded that the claimed invention meets the criterion of "world novelty", and also does not follow in an obvious way for a specialist from the existing level of science and technology, and therefore meets the criterion of "inventive step".

The essence of the claimed invention is illustrated by drawings, where: Fig. 1 is a view with a local section of the proposed device in the plane in which the rotor is located with the possibility of rotation, in the version with the rotor and the casing coaxial to each other, with the casing position corresponding to the minimum load; in fig. 2 - the same, with the position of the casing corresponding to the maximum load; in fig. 3 shows a section of the proposed device in the plane A-A in Fig. one.; in fig. 4 shows a section of the proposed device in the plane A-A in Fig. 2.

The claimed device of rotational action for generating a controlled load on a sports simulator is arranged, for example, as follows. On the foundation there are frame racks 1 (Figs. 1-4), on which, by means of closed bearings 2, a closed casing 3 in the form of a cylindrical pipe with flat sidewalls 4 is installed with the possibility of rotation, while the axis of symmetry of a cylindrical pipe 3 and flat sidewalls 4 is displaced relative to the bearings 2. On one of the flat sidewalls 4 there is a swinging handle-retainer with a spike 5. An adjusting template 6 is attached to the post 1 in the form of coaxial to the bearings 2 half-rings with grooves for placing the spike of the handle-retainer 5, sequentially located on the same radius relative to the bearings 2. Inside the closed casing 3 between the flat sidewalls 4 on the closed bearings 7 coaxially with the closed bearings 2 there is a rotor 8 in the form of an axis 9 and two round flanges 10 fixed on it, between which are fixed plates 11. The space inside the closed casing 3 between the flat sides 4 is partially filled with loading material in the form of steel balls 12, the size of which allows free passage between the plates 11. Levers 13 are rigidly attached to the ends of the axle 9, to which the pedals 14 are rotatably attached.

The inventive device of rotary action for generating a controlled load on a sports simulator in the described embodiment operates as follows. The trainee by pressing the pedal 14 tries the load to which the simulator was adjusted before the start of its training, and assesses its compliance with its physical data. In this case, the movement of the pedal causes the rotor 8 to turn, inside which steel balls 12 are poured - the energy consumption for lifting some of the balls after the plates 11 of the rotor 8 and the friction of the moving balls against each other create a load opposing the rotation of the rotor 8 . If more or less load is required for training, the trainee turns the locking handle 5 to a position parallel to the sidewalls 4 of the closed cover, and turns the closed cover 3 with the locking handle 5: if the load should be increased, the closed casing 3 is rotated, raising its axis of symmetry; if the load should be reduced, the closed casing 3 is rotated, lowering its axis of symmetry. When lifting the axis of symmetry of the closed casing 3, accordingly, the volume of its part under the rotor 8 decreases, filled with steel balls 12 under the action of their own weight - accordingly, the number of steel balls 12 located inside the rotor 8 and moved during its rotation increases , which increases the load on the trainee. When lowering the axis of symmetry of the closed casing 3, respectively, opposite actions occur and the opposite result is achieved.

Having selected the load, the trainee turns the locking handle 5 outward, driving the spike of the locking handle 5 into the groove of the adjusting template 6. In this case, the closed casing 3 is fixed relative to the adjusting template 6. Then the trainee fixes his body using a seat, steering wheel or other devices ( not shown in the figures) and by turning the pedals 14 rotates the rotor 8 with the selected load.

Thus, the claimed invention can be manufactured and used with the achievement of the claimed technical results, which proves the compliance with the criterion of "industrial applicability".
