This report refers to a patent for a gym dumbbell and, more specifically, a dynamic dumbbell for individual use and supported by one of the athlete's hands for performing bodybuilding exercise.
Como é sabido, o halter é, de forma geral, constituído por dois pesos com uma haste cilíndrica entre eles. 0 usuário pega o halter pela haste, depois de escolher o peso mais adequado ao exercício, geralmente, as academias possuem estantes ou armações para receber jogos completos de halteres, com pesos diversos. As is well known, the dumbbell is generally comprised of two weights with a cylindrical rod between them. The user picks up the dumbbell by the rod, after choosing the most appropriate weight for the exercise, usually the gyms have shelves or frames to receive complete sets of dumbbells, with different weights.
Os pesos variam de forma, mas usualmente tem formato de discos, ou esferas, ou cubos, ou prismas em geral, sem abrir mão do formato básico, de dois pesos com haste central. A massa dos pesos representa o esforço para erguê-los, mas sua inércia é importantíssima para reproduzir com muito realismo as forças extras exigidas para sua aceleração, no movimento. Weights vary in shape, but usually have the shape of discs, or spheres, or cubes, or prisms in general, without giving up the basic two-weight central-rod shape. The mass of the weights represents the effort to lift them, but their inertia is very important to very realistically reproduce the extra forces required for their acceleration in movement.
No entanto, a maior parte dos exercícios de musculação realizados em academias é feita por meio desses pequenos halteres convencionais, um para cada mão, com pesos fixos ou com discos extras para compor peso desejado. However, most gym exercises are done using these small conventional dumbbells, one for each hand, with fixed weights or extra disks to make up the desired weight.
Apesar de sua utilização satisfatória a sua ação é praticamente estática no que tange ao peso ou esforço exigido do atleta. Despite its satisfactory use, its action is practically static with respect to the athlete's weight or effort required.
Quanto à parte funcional, nada ainda foi feito, a esses halteres convencionais para fornecer ao usuário, algo além de seu peso e sua inércia.
É, pois um dos objetivos da presente invenção prover um halter para ginástica que agregue ao halter tradicional características novas, que produzam efeitos fisiológicos novos. Assim, a presente invenção pretende prover um halter para ginástica que proporcione em um único equipamento um dinamismo e uma variável no que tange ao peso a ser oferecido ao atleta. As for the functional part, nothing has yet been done to these conventional dumbbells to provide the user with anything but their weight and inertia. It is therefore an object of the present invention to provide a gymnastics dumbbell that adds to the traditional dumbbell new characteristics that produce new physiological effects. Thus, the present invention aims to provide a gym dumbbell that provides in a single equipment a dynamism and a variable regarding the weight to be offered to the athlete.
Outro objetivo da presente invenção é prover um halter para ginástica que proporcione uma situação de conforto junto a região de pega manual do equipamento. Another object of the present invention is to provide a gym dumbbell that provides a comfortable situation near the hand grip region of the equipment.
Outro objetivo da presente invenção é prover um halter para ginástica que, além de oferecer uma carga dinâmica a ser suportada pelo atleta, promova uma vibração, no braço do usuário, cujo efeito fisiológico ative as células da corrente sanguínea e atue sob os vasos linfáticos, melhorando o exercício dos músculos. Another object of the present invention is to provide a gym dumbbell which, in addition to offering a dynamic load to be borne by the athlete, promotes a vibration in the user's arm whose physiological effect activates bloodstream cells and acts under the lymphatic vessels, improving muscle exercise.
Esses e outros objetivos e vantagens da presente invenção são alcançados com um halter para ginástica, constituído por um corpo cilíndrico oco, com três cavidades contíguas, formadas por duas tampas nas extremidades e duas paredes radiais intermediárias, entre as quais se fixa, concêntricamente, um manipulo cilíndrico, acessível através de uma janela da parede do corpo; sendo esse manipulo tubular, provido internamente de pelo menos dois rolamentos onde está montado um eixo, cujas extremidades atravessam as paredes e recebem volantes com pesos excêntricos, situados nas cavidades extremas do corpo, tendo uma delas um motor elétrico engatado ao volante, e a outra cavidade extrema um contrapeso, tendo seu volante uma
hélice e a tampa respectiva, sendo que na parede são providos furos para passagem de ar bombeado pela hélice. These and other objects and advantages of the present invention are achieved with a gymnastic dumbbell consisting of a hollow cylindrical body with three contiguous cavities formed by two end caps and two intermediate radial walls, between which a concentric fixation is fixed. cylindrical handle accessible through a body wall window; this tubular handle being internally provided with at least two bearings on which an axle is mounted, the ends of which pass through the walls and receive eccentric weight flywheels located in the extreme cavities of the body, one of which has an electric motor engaged to the flywheel, and the other extreme cavity a counterweight having its steering wheel a propeller and its cover, with holes in the wall provided for air to be pumped through the propeller.
A seguir a presente invenção será descrita com referência aos desenhos anexos, nos quais: In the following the present invention will be described with reference to the accompanying drawings in which:
A figura 1 representa uma vista em elevação do halter para ginástica, objeto da presente invenção; Figure 1 is an elevational view of the gym dumbbell object of the present invention;
A figura 2 representa uma vista em planta do halter para ginástica, ilustrado na figura 1; Fig. 2 is a plan view of the gym dumbbell illustrated in Fig. 1;
A figura 3 representa um corte longitudinal do halter para ginástica, objeto da presente invenção; e Figure 3 is a longitudinal section of the gym dumbbell object of the present invention; and
A figura 4 representa uma vista em perspectiva do halter para ginástica, ilustrado nas figuras anteriores. Figure 4 is a perspective view of the gym dumbbell illustrated in the previous figures.
De acordo com essas ilustrações, o halter para ginástica, objeto da presente invenção, agrega ao peso e à inércia componentes dinâmicos de frequências variáveis, até 60 Hz, que promovem no equipamento efeitos de reação a mudanças de direção e ventilação forçada. According to these illustrations, the gymnastics dumbbell, object of the present invention, adds to the weight and inertia dynamic components of variable frequencies, up to 60 Hz, that promote in the equipment effects of reaction to changes of direction and forced ventilation.
Isso é obtido com um halter dinâmico constituído por um corpo 1, cilíndrico ou em forma de barril, totalmente oco, tendo duas tampas 2 nas extremidades e duas paredes 3 radiais, que dividem a parte interna oca em três cavidades. Na cavidade central, entre as paredes 3 é montado um manipulo 4, cilíndrico ou fusiforme, coaxial ao corpo 1, o qual é tubular e possui rolamentos 5 que seguram um eixo 6, o qual se projeta através das paredes 3, dentro das cavidades contíguas do corpo 1, onde suas extremidades se prendem a volantes 7. This is achieved with a fully hollow, dynamic barrel 1, cylindrical or body-shaped dumbbell 1 having two end caps 2 and two radial walls 3 which divide the hollow inner part into three cavities. In the central cavity, between the walls 3 is mounted a cylindrical or fusiform handle 4, coaxial to the body 1, which is tubular and has bearings 5 that hold an axis 6, which projects through the walls 3, into the contiguous cavities. from body 1, where its ends are attached to flywheels 7.
Como pode ser visto na figura 4, a parede do corpo 1, entre as paredes 3, apresenta um vão ou uma janela
8, de tamanho que permite a passagem da mão do usuário, quando este segura o halter pelo manipulo 4. As can be seen from figure 4, the wall of the body 1 between the walls 3 has a gap or a window 8, which allows the hand of the user to pass when holding the dumbbell by the handle 4.
A figura 3 mostra que em uma cavidade extrema do corpo 1, é montado, coaxialmente, um motor 9 elétrico, próximo ao volante 7, ao qual seu eixo se acopla, para transmitir o movimento de rotação. Já na cavidade do corpo 1, extrema e oposta à do motor 9, aloja-se um contrapeso 10, de massa similar à do motor 9. O volante 7 dessa cavidade extrema oposta ao motor 9, recebe uma hélice 11, sendo que a tampa 2 do corpo 1 e a parede 3 radial desse lado possuem furos 12 por onde circula o ar, bombeado pela hélice 11, que chega ao compartimento central onde está o manipulo 4. Figure 3 shows that in an extreme cavity of body 1, an electric motor 9 is mounted coaxially next to the flywheel 7 to which its axis engages to transmit the rotational motion. Already in the cavity of the body 1, extreme and opposite to the one of the motor 9, a counterweight 10 is housed, similar in mass to the one of the motor 9. The flywheel 7 of this extreme cavity opposite the motor 9 receives a propeller 11, and the cover 2 of the body 1 and the radial wall 3 on this side have holes 12 through which air circulates, pumped by the propeller 11, which reaches the central compartment where the handle 4 is.
Para favorecer o apoio do halter sobre superfícies planas, a periferia próxima às tampas 2 recebe anéis 13 salientes flexíveis, conforme pode ser visto nas figuras . In order to support the dumbbell support on flat surfaces, the periphery next to the caps 2 receives flexible protruding rings 13, as shown in the figures.
Preferencialmente, todo o corpo do halter pode ser revestido com material flexível, macio, para tornar seu manuseio seguro. Preferably, the entire dumbbell body may be coated with flexible, soft material to make its handling safe.
As figuras mostram que um cabo elétrico 14 comunica o halter com uma fonte de energia elétrica. Cada volante 7 possui contrapeso ou furos destinados a tornar suas massas excêntricas ao eixo 6. A fonte de energia elétrica pode possuir um regulador de rotação do motor 9. The figures show that an electric cable 14 communicates the dumbbell with an electrical power source. Each flywheel 7 has counterweight or holes designed to make its masses eccentric to shaft 6. The power source may have a motor speed regulator 9.
Em outra forma construtiva, o próprio halter pode possuir regulagem de rotação do motor e um mostrador digital para indicar a frequência da rotação do motor. In another embodiment, the dumbbell itself may have engine speed regulation and a digital display to indicate the frequency of motor rotation.
Assim, para sua utilização dinâmica, o halter é ligado à fonte de energia elétrica, para que o usuário
sintonize uma frequência que corresponde à rotação do motor. Thus, for its dynamic use, the dumbbell is connected to the power source, so that the user tune to a frequency that corresponds to the engine speed.
Ao girar o eixo 6, os volantes 7, com suas massas excêntricas, transmitem ao corpo do halter vibração na frequência da rotação. Segurando o halter pelo manipulo 4, o usuário recebe, além do peso e da inércia, a vibração e o efeito giroscópio, sob forma de reações a movimentos angulares . By rotating the shaft 6, the handwheels 7, with their eccentric masses, transmit to the halter body vibration at the frequency of rotation. Holding the dumbbell by the handle 4, the user receives, in addition to weight and inertia, vibration and gyro effect in the form of reactions to angular movements.
A vibração, quando o halter está na posição horizontal ou próxima, tende a aumentar a força vertical, somando à força-peso a massa girante excêntrica vezes a gravidade . Vibration, when the dumbbell is in or near the horizontal position, tends to increase the vertical force by adding to the weight-force the eccentric rotating mass times gravity.
A vibração, no braço do usuário também tem o efeito fisiológico de agitar as células, o sangue e os vasos linfáticos, melhorando assim o exercício dos músculos. Dependendo da frequência sintonizada, o exercício fica mais intenso, no mesmo halter. Vibration in the user's arm also has the physiological effect of shaking the cells, blood and lymphatic vessels, thereby improving muscle exercise. Depending on the tuned frequency, the exercise gets more intense in the same dumbbell.
0 ventilador interno, constituído pela hélice 11, faz com que o ar sopre pela janela 8, percorrendo a mão e o braço do usuário, tendendo e eliminar calor gerado pelos músculos desse braço. The internal fan, consisting of the propeller 11, causes air to blow through the window 8, running through the user's hand and arm, tending and eliminating heat generated by the muscles of that arm.
A cavidade central do halter, pode resumir-se ao manipulo 4 entre as paredes 3, sendo ele o responsável pela estabilidade de todo o conjunto. The central cavity of the dumbbell can be reduced to the handle 4 between the walls 3, which is responsible for the stability of the whole set.
Em uma forma construtiva alternativa, o motor elétrico 9 pode ser externo ao halter, e possuir no eixo um engate para encaixe ao eixo 6 dos volantes 7.
In an alternative constructional form, the electric motor 9 may be external to the dumbbell and have a coupling for engagement with the axle 6 of the flywheels 7.
