Description

SISTEMA INTELIGENTE DE PEDALAR INTELLIGENT PEDALING SYSTEM
[001] Refere-se a presente patente de invenção a um sistema diferencial de pedalar. Inserido no campo técnico da engenharia mecânica, mais precisamente em sistemas para aprimoramento do uso de energia mecânica aplicados a veículos de propulsão humana, o aparato consiste em um contrapeso angulado justaposto ao sistema de transmissão de bicicletas/triciclos e afins. [001] The present invention refers to a differential pedaling system. Inserted in the technical field of mechanical engineering, more precisely in systems for improving the use of mechanical energy applied to human-powered vehicles, the apparatus consists of an angled counterweight juxtaposed to the transmission system of bicycles/tricycles and the like.
[002] O conjunto desenvolvido pode ser adaptado nos equipamentos já existentes ou fabricados em novos modelos. Permitindo uma grande acessibilidade e aplicabilidade da tecnologia. [002] The developed set can be adapted in existing equipment or manufactured in new models. Allowing great accessibility and applicability of technology.
Descrição do estado da técnica: Description of the state of the art:
[003] A história da bicicleta começa através do desenvolvimento da "draisiana", no começo do século XVIII, uma bicicleta rudimentar, idealizada como brinquedo, que permitia curvas com a manutenção do equilíbrio, com um modesto sistema de freios e ainda sem a propulsão através de pedais. Ainda neste século, Pierre Michaux, apoiando- se no desenho original da draisiana, desenvolve um sistema de propulsão através de pedais introduzidos ligados diretamente à roda dianteira, recebendo o nome de Velocípede [003] The history of the bicycle begins with the development of the "draisiana", at the beginning of the 18th century, a rudimentary bicycle, idealized as a toy, which allowed curves with the maintenance of balance, with a modest braking system and still without the propulsion. through pedals. Still in this century, Pierre Michaux, based on the original design of the draisiana, developed a propulsion system through introduced pedals connected directly to the front wheel, receiving the name of Velocipede.
[004] A Revolução Industrial, ao longo dos séculos XVIII e XIX, foi um momento de inúmeras transformações dentro da organização social até então vigente. Destaca-se a revolução que ocorreu no setor de transportes, com os veículos de impulsão humana ganhando espaço como alternativa de lazer e transporte barato, até o desenvolvimento dos meios de transporte a motor. [004] The Industrial Revolution, throughout the 18th and 19th centuries, was a time of countless transformations within the social organization in force until then. The revolution that took place in the transport sector stands out, with human-powered vehicles gaining ground as an alternative for leisure and cheap transport, until the development of motor transport.
[005] Nos anos que se sucederam, os veículos a motor foram largamente empregados e valorizados em detrimento dos de propulsão humana. Hoje, como resultado desta política, a mobilidade nas grandes cidades tem acarretado mais poluição, emissões de gases de efeito estufa, congestionamentos, riscos de vida e de ferimentos graves, ruídos e rupturas em comunidades e nos ecossistemas. [006] Nesse contexto, a mobilidade urbana a partir do uso de veículos sustentáveis tem adquirido notória importância. A bicicleta é o meio de transporte que apresenta o menor consumo de energia primária em MJ (Mega Joule) por passageiro-km. Já o automóvel, é o modo que apresenta o maior consumo. [005] In the years that followed, motor vehicles were widely used and valued at the expense of human-powered vehicles. Today, as a result of this policy, mobility in large cities has resulted in more pollution, greenhouse gas emissions, congestion, risks to life and serious injury, noise and disruption to communities and ecosystems. [006] In this context, urban mobility based on the use of sustainable vehicles has acquired considerable importance. The bicycle is the means of transport that has the lowest primary energy consumption in MJ (Mega Joule) per passenger-km. The car, on the other hand, is the mode with the highest consumption.
[007] Não poluente, silenciosa, econômica, discreta e acessível a todos os membros da família, a bicicleta é o meio de transporte mais rápido e eficiente nos trajetos urbanos curtos, além de garantir uma melhor acessibilidade à população. A Comissão Europeia menciona que "os benefícios potenciais ou comprovados da utilização da bicicleta nunca poderão ser estabelecidos de modo exaustivo". [007] Non-polluting, silent, economical, discreet and accessible to all family members, the bicycle is the fastest and most efficient means of transport on short urban journeys, in addition to ensuring better accessibility to the population. The European Commission mentions that "the potential or proven benefits of cycling can never be exhaustively established".
[008] Por toda essa conjunção de elementos, e na atual busca por meios de transporte alternativos, a produção de bicicletas tem evoluído de forma importante, contando já com motorização elétrica combinada à propulsão humana e diversos outros fatores que oferecem ao usuário segurança, conforto e desempenho. De simples e básico meio de transporte, a bicicleta evoluiu para uso no lazer, esporte e, também, para a mobilidade urbana eficiente. [008] For all this conjunction of elements, and in the current search for alternative means of transport, the production of bicycles has evolved in an important way, already counting on electric motorization combined with human propulsion and several other factors that offer the user safety, comfort and performance. From a simple and basic means of transport, the bicycle has evolved for use in leisure, sport and also for efficient urban mobility.
[009] A diversidade de opções de modelos de bicicletas/triciclos no mercado impressiona. São opções que visam contemplar não só o lazer, mas também ferramentas de trabalho, especialmente nos casos de delivery, e não menos importante, instrumentos de locomoção aplicados a diversos fins. [009] The diversity of options for bicycle/tricycle models on the market is impressive. These are options that aim to contemplate not only leisure, but also work tools, especially in cases of delivery, and not least, locomotion instruments applied to various purposes.
[0010] No aspecto das patentes desenvolvidas e no estado da técnica como um todo, a situação não se destoa. É possível encontrar diversos modelos e tecnologias que visam o aprimoramento destes veículos, a partir de diversas propostas, desde a redução de peso, motores elétricos ou híbridos até designs desenvolvidos para aumentar a eficiência aerodinâmica. Entretanto, as propostas de alteração do funcionamento padrão são raras. Poucas modernizações relacionadas às correntes foram feitas. [0010] Regarding the patents developed and the state of the art as a whole, the situation is not different. It is possible to find several models and technologies that aim to improve these vehicles, from different proposals, from weight reduction, electric or hybrid engines to designs developed to increase aerodynamic efficiency. However, proposals to change the default functioning are rare. Few chain-related modernizations were made.
[0011] Algumas destas soluções são apresentadas nos documentos de patente descritos em sequência: CN1080901A divulga um mecanismo para manter o pedal esquerdo no terceiro quadrante do sistema de coordenadas retangulares. Seu princípio é que dois pedais, duas manivelas maiores, dois pregos de manivela, eixo central e roda dentada são integrados em um todo e o centro de gravidade que está originalmente na linha central do eixo é deslocado por contrapeso. [0011] Some of these solutions are presented in the patent documents described below: CN1080901A discloses a mechanism to keep the left pedal in the third quadrant of the rectangular coordinate system. Your principle is that two pedals, two larger cranks, two crank studs, center axle and sprocket are integrated into a whole and the center of gravity which is originally on the axle centerline is offset by counterweight.
[0012] TW201236891 fornece um contrapeso, que é adaptado para uma roda de bicicleta, compreende uma parte de conexão e duas partes de contrapeso. A parte de conexão é feita por um material moldável por flexão. As porções de contrapeso se conectam respectivamente a duas extremidades distais da porção de conexão. Desse modo, os usuários podem dobrar a parte de conexão para prender o contrapeso à roda da bicicleta e, assim, contrabalancear uma estrutura excêntrica da roda. [0012] TW201236891 provides a counterweight, which is adapted for a bicycle wheel, comprises a connecting part and two counterweight parts. The connecting part is made of a bendable material. The counterweight portions respectively connect to two distal ends of the connecting portion. In this way, users can bend the connecting part to attach the counterweight to the bicycle wheel and thus counterbalance an eccentric wheel structure.
[0013] US2014028079A1 protege uma roda de bicicleta incluindo um aro com um ou mais conjuntos de contrapeso. O conjunto de contrapeso inclui um receptor conectado ao aro e um contrapeso que está conectado ao receptor. [0013] US2014028079A1 protects a bicycle wheel including a rim with one or more counterweight assemblies. The counterweight set includes a receiver attached to the rim and a counterweight that is attached to the receiver.

[0014] Diferentemente dos produtos comumente encontrados no mercado e dos pedidos de patentes descritos, a presente invenção, escopo deste documento, tem por finalidade substituir o sistema de transmissão de movimento por manivela que aciona a coroa da bicicleta, por um sistema de braço de alavanca e contrapeso, com rendimento mecânico muito superior as demais tecnologias. [0014] Unlike the products commonly found on the market and the patent applications described, the present invention, scope of this document, aims to replace the movement transmission system by crank that drives the crown of the bicycle, for a system of arm of lever and counterweight, with a mechanical performance far superior to other technologies.
[0015] Além do mais, tem o propósito de ser adaptado nos veículos de propulsão humana já fabricados, como bicicletas, triciclos e até pedalinhos. A partir de um procedimento simples de troca e substituição de peças. Seus detalhes podem ser melhor compreendidos pela seguinte descrição detalhada em consonância com as figuras em anexo, onde: [0015] Furthermore, it is intended to be adapted to human-powered vehicles already manufactured, such as bicycles, tricycles and even pedal boats. From a simple procedure for exchanging and replacing parts. Its details can be better understood by the following detailed description in line with the attached figures, where:
Afigura 1 refere-se a uma representação esquemática, em vista isométrica, do aparato (1) empregado no sistema inteligente de pedalar, no qual (CP) refere-se a um contrapeso, (P) a um pedal genérico e (E) a região no qual será inserido um eixo para transmissão do movimento. Figure 1 refers to a schematic representation, in isometric view, of the apparatus (1) used in the intelligent pedaling system, in which (CP) refers to a counterweight, (P) to a generic pedal and (E) to region in which an axis will be inserted to transmit the movement.
Afigura 2 identifica o mesmo aparato (1), em vista frontal. Descrição detalhada da invenção: Figure 2 identifies the same apparatus (1), in front view. Detailed description of the invention:
[0016] O sistema inteligente de pedalar é empregado a partir da inserção do aparato (1) no eixo da coroa dos veículos de propulsão humana. Notadamente, para o correto funcionamento da tecnologia, é necessário um aparato (1) para cada lado do veículo (bicicleta, triciclo, pedalinho, etc.) [0016] The intelligent pedaling system is used from the insertion of the apparatus (1) on the crown axis of human-powered vehicles. Notably, for the correct functioning of the technology, an apparatus (1) is required for each side of the vehicle (bicycle, tricycle, pedal boat, etc.)
[0017] Podendo ser fabricado a partir de diversos materiais metálicos, como o alumínio ou aço, não se limitando aos mesmos, o aparato (1) possui uma região central (E) para inserção do eixo da coroa da bicicleta ou veículo afim. O contrapeso (CP) pode ser produzido em diversos modelos e formas, especialmente a partir de materiais com elevado peso específico, como o chumbo. [0017] It can be manufactured from various metallic materials, such as aluminum or steel, but not limited to them, the apparatus (1) has a central region (E) for inserting the crown axle of the bicycle or similar vehicle. Counterweight (CP) can be produced in different designs and shapes, especially from materials with a high specific weight, such as lead.
[0018] O contrapeso (CP) possui a função de retornar o pedal a uma posição vertical superior, após o ciclista exercer uma força de cima para baixo sobre o mesmo. A partir destes mecanismos não será necessário efetuar o clássico movimento circular para pedalar, e sim, um movimento de "sobe e desce". Essas alterações servem para otimizar o esforço do usuário com auxílio da gravidade e, também, prevenir desgastes e lesões na região do joelho. [0018] The counterweight (CP) has the function of returning the pedal to a higher vertical position, after the cyclist exerts a downward force on it. From these mechanisms it will not be necessary to make the classic circular movement to pedal, but an "up and down" movement. These changes serve to optimize the user's effort with the aid of gravity and also prevent wear and tear and injuries in the knee region.
[0019] A angulação de 45Q referente ao centro de massa do contrapeso (CP) e o eixo central, conforme figura 2, garante a máxima eficiência para o mecanismo. A tecnologia possui versatilidade para adaptação nos veículos já fabricados ou o emprego em novos modelos. [0019] The angulation of 45 Q referring to the center of mass of the counterweight (CP) and the central axis, as shown in figure 2, guarantees maximum efficiency for the mechanism. The technology has versatility for adaptation in vehicles already manufactured or use in new models.
[0020] A substituição do sistema de transmissão de movimento por manivela que aciona a coroa da bicicleta, normalmente utilizado, por um sistema de braço de alavanca e contrapeso garante um rendimento mecânico muito superior as demais tecnologias, reduzindo o esforço e o gasto energético, garantindo um menor consumo de energia primária por passageiro-km. [0020] The replacement of the movement transmission system by crank that drives the bike's crown, normally used, by a lever arm and counterweight system guarantees a mechanical performance much superior to other technologies, reducing effort and energy expenditure, ensuring lower primary energy consumption per passenger-km.
[0021] Embora descrita esta modalidade da presente patente de invenção, será entendido por aqueles versados na técnica que várias mudanças, modificações, substituições ou alterações podem ser feitas sem se afastar do princípio e do espírito da presente invenção. [0021] While this embodiment of the present invention is described, it will be understood by those skilled in the art that various changes, modifications, substitutions or alterations may be made without departing from the principle and spirit of the present invention.
