[001] Hoje em dia a grande maioria dos equipamentos de musculação utilizam placas de ferro ou anilhas como carga para o usuário se exercitar. [001] Nowadays the vast majority of bodybuilding equipment use iron plates or washers as a load for the user to exercise.
[002] A fim de substituir as placas e anilhas de ferro dos equipamentos de musculação usuais, surgiram os equipamentos que utilizam sistemas pneumáticos com pistões, compressores de ar e válvulas pneumáticas de controle que aumentam ou reduzem a pressão do sistema e assim fazem a mudança da resistência e, consequentemente, esforço solicitado ao usuário. [002] In order to replace the iron plates and washers of the usual bodybuilding equipment, equipment that uses pneumatic systems with pistons, air compressors and pneumatic control valves that increase or reduce the pressure of the system and thus make the change resistance and, consequently, the effort required from the user.
Sumário da Invenção Summary of the Invention
[003] A presente invenção utiliza um sistema mecânico-pneumático para equipamentos de musculação, que proporciona a alteração resistência escolhido pelo usuário para se exercitar sem a utilização de compressores de ar e válvulas pneumáticas. [003] The present invention uses a mechanical-pneumatic system for bodybuilding equipment, which provides the resistance change chosen by the user to exercise without the use of air compressors and pneumatic valves.
[004] Esse sistema consiste em um pistão pneumático de pressão interna fixa pré-pressurizado que é acionado por um cabo ou correia/corrente que passam por polias ou coroas ou, por um mecanismo de pinhão e cremalheira, transmitindo, por reação, o esforço de compressão do ar dentro do pistão pneumático a um eixo para encaixe de uma polia que possui cabo próprio. [004] This system consists of a pre-pressurized fixed internal pressure pneumatic piston that is driven by a cable or belt/chain that passes through pulleys or crowns or, through a rack and pinion mechanism, transmitting, by reaction, the effort of air compression inside the pneumatic piston to an axle to fit a pulley that has its own cable.
[005] O usuário determina a resistência para a execução do exercício através da escolha do diâmetro da polia a ser fixada no eixo previamente citado, no qual quanto maior o diâmetro da polia, menos esforço será realizado pelo usuário e, quanto menor o diâmetro da polia, mais esforço será realizado pelo usuário. [005] The user determines the resistance for performing the exercise by choosing the diameter of the pulley to be fixed on the previously mentioned axis, in which the greater the diameter of the pulley, the less effort will be performed by the user and, the smaller the diameter of the pulley, more effort will be performed by the user.
[006] Ou seja, cada diâmetro da polia determina um esforço realizado pelo usuário e, para melhor compreensão pelo usuário, os diâmetros das polias são convertidos em quilograma, unidade já utilizada como referência de resistência em equipamentos de musculação usuais. [007] Com esse sistema pneumático mecânico, além da eliminação do compressor de ar e de válvulas pneumáticas para a alteração de resistência que o usuário pode escolher, há a enorme vantagem de não haver o consumo de energia elétrica pelo compressor a todo o momento. [006] That is, each pulley diameter determines an effort made by the user and, for a better understanding by the user, the diameters of the pulleys are converted into kilograms, a unit already used as a reference of resistance in usual bodybuilding equipment. [007] With this mechanical pneumatic system, in addition to eliminating the air compressor and pneumatic valves for changing the resistance that the user can choose, there is the enormous advantage of not having the compressor consume electricity at all times.

Descrição Detalhada da Invenção Detailed Description of the Invention
[0014] O sistema mecânico-pneumático com polias de diversos diâmetros da presente invenção compreende: a) pelo menos um pistão pneumático com pressão fixa (3); b) pluralidade de polias (1 ) com diâmetros diferentes; c) eixo (6); d) meios para fixar acessório para permitir o giro da polia (1 ); e) meios para fixar uma polia (1 ) no eixo (6); e f) meios transferir a rotação do eixo (6) para atuação do pistão pneumático com pressão fixa (3). [0014] The mechanical-pneumatic system with pulleys of different diameters of the present invention comprises: a) at least one pneumatic piston with fixed pressure (3); b) plurality of pulleys (1) with different diameters; c) axis (6); d) means for fixing the accessory to allow the pulley to turn (1); e) means for fixing a pulley (1) on the shaft (6); and f) means transferring the rotation of the shaft (6) to actuate the pneumatic piston with fixed pressure (3).
[0015] Como pode ser visto como exemplo na Figura 1 , o sistema mecânico-pneumático descrito pode ser utilizado em qualquer equipamento de musculação (2) desde que possibilite ao usuário a escolha das polias (1 ) com os diâmetros já convertidos em quilograma. [0015] As can be seen as an example in Figure 1, the mechanical-pneumatic system described can be used in any bodybuilding equipment (2) as long as it allows the user to choose the pulleys (1) with the diameters already converted into kilograms.
[0016] O presente sistema mecânico pneumático, como pode ser visto na Figura 2, será composta por polia (1) de diversos diâmetros para escolha da resistência solicitada ao usuário, uma estrutura de um equipamento de musculação (2), um pistão pneumático de pressão fixa (3) pré-pressurizado para criar resistência ao exercício, roldanas (4) para direcionar o cordelete (5) que puxa a haste do pistão pneumático (3) comprimindo internamente o ar, um eixo (6) no qual a polia (1 ) é fixada e que, ao girar, enrola o cordelete (5) como um carretel tracionando-o e puxando o pistão pneumático de pressão fixa (3), comprimindo o ar, mancais (7) que suportam o eixo (6) que, por sua vez, são fixos na estrutura do equipamento de musculação (2), além disso, utiliza-se meios de fixação conhecidos, como por exemplo uma presilha (8) para fixação axial das polia (1 ) e um reservatório de ar (9) para controle do aumento de pressão na compressão do ar dentro do pistão pneumático de pressão fixa (3). [0016] The present pneumatic mechanical system, as can be seen in Figure 2, will consist of a pulley (1) of different diameters to choose the resistance requested from the user, a structure of a bodybuilding equipment (2), a pneumatic piston of fixed pressure (3) pre-pressurized to create resistance to the exercise, pulleys (4) to direct the cord (5) that pulls the rod of the pneumatic piston (3) internally compressing the air, an axle (6) in which the pulley ( 1 ) is fixed and which, when turning, winds the cord (5) like a spool pulling it and pulling the fixed pressure pneumatic piston (3), compressing the air, bearings (7) that support the shaft (6) that , in turn, are fixed to the bodybuilding equipment structure (2), in addition, known fastening means are used, such as a clip (8) for axial fixation of the pulleys (1) and an air reservoir ( 9) to control the increase in pressure when compressing the air inside the fixed pressure pneumatic piston (3).
[0017] Cada polia, como pode ser visto na Figura 3, será composta por meios para fixar acessório para permitir o giro da polia, como por exemplo um mosquetão (10) para que seja fixado um acessório para as mãos, pernas ou cinto, ou qualquer outro acessório que permita a realização do exercício, um terminal (11 ) para fixação do mosquetão (10) e um cordelete da polia (12) fixo no terminal (11 ) e nas polias (101 , 102, 103). [0017] Each pulley, as can be seen in Figure 3, will consist of means to attach an accessory to allow the pulley to turn, such as a carabiner (10) to attach an accessory to the hands, legs or belt, or any other accessory that allows the exercise to be carried out, a terminal (11) for attaching the carabiner (10) and a pulley cord (12) fixed to the terminal (11) and pulleys (101, 102, 103).
[0018] Ainda com relação à Figura 3, quanto maior o diâmetro da polia, menor será a resistência solicitada ao usuário para realização do exercício, ou seja, a polia com diâmetro correspondente à 10kg (101 ) será maior que a polia com diâmetro correspondente á 15kg (102) e que, consequentemente, será maior que a polia com diâmetro correspondente á 20kg (103). [0018] Still referring to Figure 3, the larger the pulley diameter, the lower the resistance requested from the user to perform the exercise, that is, the pulley with a diameter corresponding to 10kg (101 ) will be larger than the pulley with a corresponding diameter will weigh 15kg (102) and which, consequently, will be larger than the pulley with a diameter corresponding to 20kg (103).
[0019] O sistema mecânico pneumático pode ser visto montado na sua posição inicial na Figura 4, no qual o usuário escolhe a polia (1 ) com diâmetro correspondente à carga que deseja fazer o exercício fixando-a no eixo (6), suportado por mancais (7), e prendendo axialmente através de uma presilha (8), permitindo assim o início do funcionamento do sistema que, ao puxar o cordelete da polia (1 ), a polia (1 ) gira e transfere o movimento ao eixo (6) por meios comumente conhecidos da técnica, como por exemplo roldanas e cordeletes, que, por sua vez, enrola o cordelete (5) tracionando-o e, consequentemente, puxa a haste do pistão pneumático de pressão fixa (3) de forma linear, garantido pela mudança de direção do cordelete (5) provocado pelas roldanas (4), comprimindo o ar dentro do pistão pneumático de pressão fixa (3), no qual o aumento de pressão será controlado pelo reservatório de ar (9) para que não haja aumento excessivo da resistência durante o exercício. [0019] The pneumatic mechanical system can be seen assembled in its initial position in Figure 4, in which the user chooses the pulley (1 ) with a diameter corresponding to the load he wants to exercise, fixing it on the shaft (6), supported by bearings (7), and securing axially through a clip (8), thus allowing the start of the system operation that, when pulling the pulley cord (1 ), the pulley (1 ) rotates and transfers the movement to the shaft (6 ) by means commonly known in the art, such as pulleys and cords, which, in turn, wind the cord (5) pulling it and, consequently, pull the fixed pressure pneumatic piston rod (3) linearly, guaranteed by the change in direction of the cord (5) caused by the pulleys (4), compressing the air inside the fixed pressure pneumatic piston (3), in which the pressure increase will be controlled by the air reservoir (9) so that there is no Excessive increase in resistance during exercise.
[0020] A posição final do sistema mecânico pneumático após uma repetição do exercício pode ser visto na Figura 5, onde o pistão pneumático de pressão fixa (3) está com a haste totalmente esticada, correspondendo à compressão máxima do ar resultando em um aumento de resistência que é controlado pelo reservatório de ar (9), as roldanas (4) mantendo a linearidade do pistão pneumático de pressão fixa (3) e direcionando o cordelete (5) que está totalmente enrolado no eixo (6), esse que é suportado pelos mancais (7) e, a polia (1 ) se mantém fixada no eixo (6) e fixa axialmente pela presilha (8), porém com o seu cordelete totalmente esticado. [0020] The final position of the pneumatic mechanical system after a repetition of the exercise can be seen in Figure 5, where the fixed pressure pneumatic piston (3) has the rod fully stretched, corresponding to the maximum compression of the air resulting in an increase of resistance which is controlled by the air reservoir (9), the pulleys (4) maintaining the linearity of the fixed pressure pneumatic piston (3) and directing the cord (5) which is fully wound on the shaft (6), which is supported by the bearings (7) and, the pulley (1) remains attached to the shaft (6) and fixed axially by the clip (8), but with its string fully stretched.
[0021] O pistão com pressão fixa (3) estará sempre com somente uma das suas câmaras internas pressurizadas, e a escolha do melhor arranjo mecânico é dependente do exercício a ser realizado. Sendo assim, o sistema pode funcionar para proporcionar a resistência e carga para o usuário, puxando ou empurrando a haste do pistão (3). [0021] The piston with fixed pressure (3) will always have only one of its internal chambers pressurized, and the choice of the best arrangement mechanical is dependent on the exercise to be performed. Therefore, the system can work to provide resistance and load to the user, pulling or pushing the piston rod (3).
[0022] Além disso, o sistema pode ser projetado para ter um arranjo mecânico onde uma polia (1 ) acione mais de um pistão (3). Um técnico no assunto entenderá essa pluralidade de configurações e será capaz de projetar um sistema e equipamento que atenda as necessidades de esforço do usuário sem dificuldade. Todas essas combinações de configurações estão dentro do escopo da presente invenção. [0022] In addition, the system can be designed to have a mechanical arrangement where a pulley (1) drives more than one piston (3). A person skilled in the art will understand this plurality of configurations and will be able to design a system and equipment that meets the user's effort needs without difficulty. All these configuration combinations are within the scope of the present invention.
