Description

Technology area

The proposed technical solution relates to the field of sports and can be used as a built-in module as part of an already existing sports training device or in the development of new designs of sports training devices. The proposed device can be used on sports training equipment both in fitness studios and on outdoor sports fields, since it has vandalism-proof properties.

State of the art

A flywheel with a shoe brake is known from the prior art, which is mounted on the frame shaft of a DFC B3005 exercise bike (see http://www.omegasport.ru/product_6009.html) ( 1 ). The flywheel is a solid metal disk attached to the shaft, the rotation of the flywheel is transmitted by a transmission mechanism (belt drive) from the pedal device.

The main disadvantage of the known device is the high inertia of the system due to the solidity of the flywheel.

The construction of a flywheel is known which contains a hollow-chamber body attached to a shaft in which there is a bulk material (steel balls or cast iron chips), while the flywheel hub is made of magnetic material and the hollow-chamber body with a rim is made of a material that does not contain any possesses magnetic properties, are manufactured, and the bulk material interacts with a magnet (see patent for no. RU 2439394 , Class F16F 15/31).

The structural complexity and the technological difficulties in the manufacture of the drum and shaft housing are disadvantageous.

Also known is the construction of a flywheel with easy starting, which contains a hollow-wall rim filled with liquid filler, in the inner volume partitions (curtains) with holes, equipped with valves, are arranged at an angle in the inner volume (see patent for no. RU 2327910 , Class F16F 15/31). The disadvantage of the known device lies in the compliance with the requirements for the tightness of the drum body and the restriction of the material used as the load filling component.

The proposed technical solution from a technical point of view comes closest to a "device for muscle training" (prototype, patent for No. 107949, class A63B 23/00), which contains elements for torque transmission that are pivotably attached to the body (base) of a sports training device , and also executed in the form of a hollow chamber drum with a window plumb bobs, the inner cavity of which is filled with a load filling component. Load regulation is done by adding or subtracting the load filling component through the window.

The disadvantage of the prototype is the complexity of the construction. Another disadvantage is that the pendulum construction of the device limits the acquisition of an arsenal of technical means for exercising and developing the muscles of the user. In addition, the known device has a high degree of inertia, since the mass of the load filling component is at a large distance from its geometric axis of oscillation.

The disadvantages listed are eliminated in the proposed embodiment of the device for generating a load on the sports training device.

In the proposed device for generating a load on the sports training device, which includes a plumb bob, which is made in the form of a hollow chamber drum, is present in the load filling component, and elements for transmitting torque, which are movable on a corresponding portion of the body of the sport -Training device are mounted, ACCORDING TO THE TECHNICAL SOLUTION, the hollow chamber drum is made with solid surfaces and with coaxial pins that are rigidly attached to their lateral outer surfaces.

• - das Vorhandensein einer Hohlkammertrommel;
• - das Vorhandensein von Elementen zur Übertragung des Drehmoments, die beweglich am entsprechenden Abschnitt des Körpers (Basis) des Sport-Trainingsgeräts montiert sind.

The common features of the proposed technical solution and the prototype are:

• - the presence of a body (base) of a sports training device;
• - the presence of a hollow chamber drum;
• - The presence of elements for transmitting the torque, which are movably mounted on the corresponding section of the body (base) of the sports training device.

• - die Hohlkammertrommel besteht aus festen Oberflächen;
• - die Hohlkammertrommel wird mit koaxialen Stiften hergestellt, die starr an ihren seitlichen Außenflächen angebracht sind.

Distinctive key features:

• - The hollow chamber drum consists of solid surfaces;
• - The hollow chamber drum is made with coaxial pins that are rigidly attached to its lateral outer surfaces.

The presence of these essential distinguishing features ensures that the proposed technical solution complies with the condition of "novelty" of patentability.

Disclosure of a utility model

The technical result is the simplification of the construction with the achievement of a minimum inertia.

The above technical result is achieved in that the device for generating a load on the sports training device has a plumb bob in the form of a hollow chamber drum, in which load filling components are present, and elements for torque transmission movably on the corresponding section of the body of the sports training device mounted, the drum is made with solid surfaces and with coaxial pins rigidly attached to its lateral outer surfaces.

The manufacture of the drum with solid surfaces and with coaxial pins that are rigidly attached to its lateral outer surfaces made it possible to ensure the generation of a certain load on the sports training device with a minimum inertia of the moving elements of the device.

Variant of the utility model version

The technical solution is illustrated by a specific embodiment variant, which clearly shows the possibility of achieving a certain amount of essential features of the specified certain technical result.

According to the technical solution (see 1 / 1) the device for generating a load on the sports training device consists of a hollow chamber drum 1 with polished inner surface, with coaxial pins 2 which are rigidly mounted on their lateral outer surfaces. The hollow chamber drum 1 with the pens 2 is movable on the corresponding section of the body 3 of the sports training device and is manufactured with solid surfaces. The inner cavity of the drum 1 becomes one-time and partially with the load-filling component 4th filled, which is a free-flowing material or, for example, metal balls, cast iron shot or chips. A single loading of the drum 1 takes place during their manufacture. The elements for transferring the load 5 are at the respective ends of the drum 1 on the pivot 2 attached.

• Der Benutzer, der ein Sport-Trainingsgerät verwenden möchte, das mit der vorgeschlagenen Vorrichtung bei der Verwendung von Elementen zum Übertragen der Belastung 5 ausgestattet ist, die beispielsweise in Form von Hebeln mit Griffen oder Pedalen (oder anderen in der Technik bekannten Vorrichtungen zur Übertragung des Drehmoments auf die Aktuatoren von Sport-Trainingsgeräten, zum Beispiel den Ellipsoidmechanismus eines Heimtrainers, Riemen- oder Kettenantrieb an den Heimtrainerpedalen usw.), treibt die Trommel 1 mit Stiften 2 in Drehbewegung. In der Ausgangsstellung befindet sich die Belastungsfüllungskomponente 4 am Boden der Trommel 1. Bei einer bestimmten Rotationsgeschwindigkeit der Trommel 1 steigt die Belastungsfüllungskomponente 4 unter der Wirkung der Fliehkraft und infolgedessen der Reibungskraft im Körper der Trommel 1 entlang ihrer inneren Umfangsfläche an. Somit wird an den Drehzapfen 2 ein gewisses Drehmoment erzeugt. Bei einer bestimmten Rotationsgeschwindigkeit der Trommel 1 beginnt die Belastungskomponente 4 (ihre oberen Elemente) unter ihrem Eigengewicht herunterzufallen, und in diesem Fall wird die Belastung maximal.

The device for generating a load on the sports training device is operated as follows:

• The user who wants to use a sports training device that works with the proposed device when using elements for transferring the load 5 is equipped, for example in the form of levers with handles or pedals (or other devices known in the art for transmitting the torque to the actuators of sports training equipment, for example the ellipsoid mechanism of an exercise bike, belt or chain drive on the exercise bike pedals, etc.) , drives the drum 1 with pens 2 in rotary motion. The load-filling component is in the starting position 4th at the bottom of the drum 1 . At a certain speed of rotation of the drum 1 the load-filling component increases 4th under the action of centrifugal force and, as a result, the frictional force in the body of the drum 1 along its inner peripheral surface. Thus it is attached to the pivot 2 generates a certain torque. At a certain speed of rotation of the drum 1 the stress component begins 4th (their upper members) falling down under their own weight, and in this case the load becomes maximum.

This device has a minimal inertia, which is necessary for the smooth operation of the elements for transmitting the load 4th is required and is only due to the mass of the peripheral part of the drum chamber body 1 definitely.

The load required is determined by the mass of the load fill component 4th determined (e.g. 10 kg, 20 kg ... 50 kg). The user in the training process can use a selectively required sports training device that is tailored to a specific load.

By making the proposed device in the form of a non-separable module with a solid surface of a rigid construction that does not require maintenance, a vandalism-proof protection is achieved, which allows the use of the proposed device in various sports training equipment when used on outdoor sports fields.
