Abstract
Transmission system with gears or sprockets and chains or pulleys and belts or a CVT-type system for changing the resistance to drive the rod of a pre-pressurised fixed-pressure pneumatic piston. A set of mechanical relations which produce more or less resistance to drive the rod of the fixed-pressure piston is provided to the user, each of said relations having values converted into kilograms, the unit used for resistance in workout equipment. The system is used in pneumatic strength training equipment and replaces conventional equipment that uses iron plates or discs, eliminating the need for valves or air compressors to change the effort required from the user to compress the air in the pneumatic piston.
Description
SISTEMA MECÂNICO-PNEUMÁTICO PARA A ALTERAÇÃO DE RESISTÊNCIA EM EQUIPAMENTOS DE MUSCULAÇÃO E EQUIPAMENTO DE MUSCULAÇÃO MECHANICAL-PNEUMATIC SYSTEM FOR CHANGING RESISTANCE IN BODYBUILDING EQUIPMENT AND BODYBUILDING EQUIPMENT
[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 pneumático mecânico 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, ou por um mecanismo CVT, transmitindo, por reação, o esforço de compressão do ar dentro do pistão pneumático ao eixo de um câmbio cujas engrenagens ou coroas são fixas ao mesmo e, essas engrenagens ou coroas, por sua vez, transmitem o esforço e o movimento às engrenagens ou coroas de um segundo eixo. [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, by a rack and pinion mechanism, or by a CVT mechanism, transmitting , by reaction, the effort of compressing the air inside the pneumatic piston to the shaft of an exchange whose gears or crowns are fixed to it, and these gears or crowns, in turn, transmit the effort and movement to the gears or crowns of a second axis.
[005] O segundo eixo possui furos para colação de esferas e uma cavidade interna para passagem de um êmbolo de deslocamento linear. [005] The second shaft has holes for gluing balls and an internal cavity for the passage of a linear displacement piston.
[006] As engrenagens ou coroas do segundo eixo não são fixas no eixo e somete transmitem a força e o movimento das engrenagens ou coroas do primeiro eixo se o embolo estiver na posição em que a esfera se acople à engrenagem. [006] The gears or crowns of the second shaft are not fixed on the shaft and only transmit the force and movement of the gears or crowns of the first shaft if the piston is in the position where the ball is coupled to the gear.
[007] Para cada engrenagem ou coroa do segundo eixo há uma relação de força transmitida do usuário para a compressão do pistão pneumático, ou
seja, o usuário determinará a posição do êmbolo através de um selecionador que irá acoplar uma engrenagem ou coroa no segundo eixo e a relação escolhida irá determinar o esforço necessário pelo usuário para a compressão do pistão pneumático e realização do exercício. [007] For each gear or crown of the second axis there is a ratio of force transmitted from the user to the compression of the pneumatic piston, or that is, the user will determine the position of the plunger through a selector that will couple a gear or crown on the second axis and the chosen ratio will determine the effort required by the user to compress the pneumatic piston and carry out the exercise.
[008] Essas relações de força do câmbio são convertidas em quilogramas no selecionador para o usuário, já que é a unidade de esforço utilizada como referência nos equipamentos de musculação. [008] These exchange rate ratios are converted into kilograms in the selector for the user, since it is the unit of effort used as a reference in bodybuilding equipment.
[009] Em resumo, de acordo com a necessidade, a relação mecânica para se exercitar é escolhida pelo usuário no selecionador e o usuário executa então seu esforço físico no eixo de entrada deste conjunto de relações de forma direta com alavancas ou com sistemas de cabos e polias ou correntes ou, ainda, correias, principalmente se o equipamento for linear. [009] In summary, according to the need, the mechanical relationship to exercise is chosen by the user in the selector and the user then performs his physical effort on the input axis of this set of relationships directly with levers or with cable systems and pulleys or chains or even belts, especially if the equipment is linear.
[0010] Sua força passa de uma engrenagem ou coroa ou polia para a outra que está no segundo eixo o qual é o eixo que dele parte o sistema de acionamento da haste do pistão pneumático de pressão fixa podendo ser esta haste acionada por um cabo que está num carretel neste eixo saída e também, esse eixo de saída estar acoplado num sistema de pinhão e cremalheira que aciona a haste do pistão pneumático de pressão fixa que, por reação, devolve a mesma força que o usuário executou para pressurizá-lo. [0010] Its force passes from one gear or crown or pulley to the other that is on the second axis, which is the axis that starts from it the drive system of the fixed pressure pneumatic piston rod, and this rod can be driven by a cable that it is on a spool on this output shaft and also, this output shaft is coupled to a rack and pinion system that drives the fixed pressure pneumatic piston rod which, by reaction, returns the same force that the user executed to pressurize it.
[0011] 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. [0011] 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.

Thus, the system can function to provide resistance and load to the user, pulling or pushing the piston rod (24).
