Description

CONJUNTO PARA PROPULSIONAR BICICLETA COM AUXÍLIO DA ASSEMBLY TO PROVIDE BIKE WITH AID
MUSCULATURA SUPERIOR DO USUÁRIO SUPERIOR USER MUSCULATURE
Setor tecnológico do modelo Technological sector of the model
[0001 ] O presente modelo de utilidade pertence, de maneira geral, ao setor tecnológico de bicicletas e acessórios para bicicletas e se refere, de modo mais específico, a um conjunto que, ao ser acoplado aos pedais de uma bicicleta, possibilita que a musculatura superior do usuário (braços, ombros, costas, peitoral, etc.) possa ser utilizada para auxiliar na propulsão da bicicleta. [0001] The present utility model belongs, in general, to the technological sector of bicycles and bicycle accessories and refers, in a more specific way, to a set that, when coupled to the pedals of a bicycle, allows the musculature user's upper arms (arms, shoulders, back, chest, etc.) can be used to assist in propelling the bicycle.
[0002] Dito conjunto compreende uma haste com meios de ajuste do comprimento, o que possibilita adaptação às medidas antropométricas do ciclista, destinada a transferir a força da musculatura superior para o pedal da bicicleta, sendo para tanto dotada em sua extremidade livre de um manipulo de pega e na outra extremidade de meios de fixação ao pedal. [0002] Said set comprises a rod with means of adjusting the length, which allows adaptation to the anthropometric measurements of the cyclist, designed to transfer the force of the upper musculature to the bicycle pedal, being therefore endowed in its free end with a handle handle and at the other end of means of attachment to the pedal.
Estado da técnica conhecido Known state of the art
[0003] O estado da técnica desse setor tecnológico compreende bicicletas convencionais, utilizadas tanto para transporte como para exercícios, cuja impulsão é realizada exclusivamente pelos pedais, solicitando principalmente a musculatura dos pés e pernas do usuário e restringindo o esforço dos braços apenas a segurar o guidão. [0003] The state of the art of this technological sector comprises conventional bicycles, used both for transportation and for exercises, whose propulsion is carried out exclusively by the pedals, requesting mainly the musculature of the user's feet and legs and restricting the effort of the arms only to hold the handlebar.
[0004] Conhecem-se bicicletas com mecanismos auxiliares de impulsão, como a revelada no PI0803318-8 - Bicicleta Supino tração 2x2 - que acrescenta um conjunto de engrenagens acoplado a um suporte fixo na frente da bicicleta, por onde se dá a tração mecânica gerada pela força exercida pelo ciclista sobre o guidão, visando o aumento de velocidade e o desenvolvimento de músculos como trapézio, deltoides, peitoral, dorsais, bíceps, tríceps e antebraços. [0004] Bicycles with auxiliary drive mechanisms are known, such as the one shown in PI0803318-8 - Supine Bicycle 2x2 traction - which adds a set of gears coupled to a fixed support in front of the bicycle, where the mechanical traction is generated. by the force exerted by the cyclist on the handlebars, aiming at increasing speed and the development of muscles such as trapezius, deltoids, chest, back, biceps, triceps and forearms.
[0005] Sabe-se, também, do PI0902360-7 - Bicicleta com duas unidades de acionamento - que descreve uma bicicleta que inclui uma unidade de guidão que faz um movimento pivotável para frente e para trás em um eixo, por sua vez conectado a um braço operacionalmente ligado a uma unidade de acionamento de roda dianteira da bicicleta, enquanto a roda traseira é movida pelos pedais, fazendo com que a bicicleta seja operada pelas pernas e mãos. [0005] It is also known from PI0902360-7 - Bicycle with two drive units - which describes a bicycle that includes a handlebar unit that makes a pivotable movement back and forth on an axis, in turn connected to an arm operationally connected to a front wheel drive unit of the bicycle, while the rear wheel is moved by the pedals, causing the bicycle to be operated by the legs and hands.
[0006] Estas duas anterioridades revelam bicicletas com formas construtivas diferenciadas, compostas por mecanismos de transmissão relativamente complexos, compostos por uma série de partes móveis, sujeitas a desgaste e que aumentam a complexidade do processo produtivo e o preço da bicicleta em si. Isto faz com que os consumidores necessitem adquirir bicicletas que já venham de fábrica com estas alterações, certamente por um preço superior às convencionais. [0006] These two priorities reveal bicycles with different constructional forms, composed by transmission mechanisms relatively complex, composed of a series of moving parts, subject to wear and tear that increase the complexity of the production process and the price of the bike itself. This means that consumers need to purchase bicycles that already come from the factory with these changes, certainly at a higher price than conventional ones.
[0007] Não é de conhecimento do inventor nenhum conjunto de acessórios de baixo custo que possa ser adaptado de forma simples e prática a uma bicicleta convencional, permitindo que os usuários utilizem a musculatura superior para aumentar a impulsão e obtendo, como benefício secundário, o exercício da musculatura superior enquanto andam de bicicleta, sem ter que adquirir uma bicicleta exclusiva para tal finalidade. Esta possibilidade de exercitar a musculatura superior ainda torna a instalação do conjunto proposto interessante em bicicletas ergométricas. [0007] The inventor is not aware of any set of low-cost accessories that can be simply and practically adapted to a conventional bicycle, allowing users to use the upper musculature to increase the thrust and obtaining, as a secondary benefit, the exercise of the upper musculature while cycling, without having to purchase an exclusive bicycle for that purpose. This possibility of exercising the upper musculature still makes the installation of the proposed set interesting on exercise bikes.
Novidade e objetivos do modelo Novelty and objectives of the model
[0008] O presente modelo de utilidade se refere a um conjunto de acessórios que pode ser acoplado de forma simples e prática a uma bicicleta convencional pelo próprio usuário, sem a necessidade de alterações estruturais radicais no veículo ou mesmo de ferramentas especiais, auxiliando na propulsão e permitindo que seja usada para exercitar também a musculatura superior do ciclista. [0008] The present utility model refers to a set of accessories that can be coupled in a simple and practical way to a conventional bicycle by the user himself, without the need for radical structural changes in the vehicle or even special tools, assisting in propulsion and allowing it to be used to exercise the rider's upper musculature as well.
[0009] O modelo proposto compreende uma haste retrátil, que permite adaptação a usuários de diferentes alturas, dotada em uma extremidade de uma empunhadura anatômica para a mão do usuário e de meios de fixação de forma articulada ao pedal da bicicleta na extremidade oposta. Tal dispositivo permite ao ciclista aplicar a força ao pedal utilizando a sua musculatura superior (braços, ombros, costas, peitoral), empurrando-o para baixo e puxando para cima enquanto pedala, aumentando a propulsão do veículo e exercitando a sua musculatura superior. Esta construção prevê três possibilidades de montagem. A haste pode ser acoplada tanto ao pedal do lado direito como ao pedal do lado esquerdo da bicicleta, permitindo que o ciclista exercite alternadamente ambos os lados da musculatura superior, ou ainda podem ser acopladas duas hastes, uma em cada lado da bicicleta, para que exercite simultaneamente ambos os lados da musculatura superior com a bicicleta. [0010] A haste é retida no pedal, mas ainda mantém um grau de liberdade de movimento, podendo girar livremente em torno do eixo longitudinal de dito pedal. Desse modo, quando a haste está transferindo força para o pedal, o ciclista a mantém em posição substancialmente vertical, posição anatomicamente adequada para o esforço realizado pelo braço. Quando o ciclista deseja parar de usar a haste, basta soltá-la. A força da gravidade fará com que dita haste bascule para uma posição inclinada, em que não atrapalha o movimento da bicicleta ou a pedalada do ciclista, sendo que nesse momento entra em ação mais um item do conjunto proposto, uma corda flexível de sustentação que é presa a haste e ao banco da bicicleta, própria para sustentar e manter a haste nessa posição inclinada. [0009] The proposed model comprises a retractable rod, which allows adaptation to users of different heights, provided at one end with an anatomical grip for the user's hand and with means of attachment articulated to the bicycle pedal at the opposite end. Such a device allows the cyclist to apply force to the pedal using his upper musculature (arms, shoulders, back, chest), pushing him down and pulling up while pedaling, increasing the vehicle's propulsion and exercising his upper musculature. This construction provides for three mounting possibilities. The rod can be attached to both the pedal on the right side and the pedal on the left side of the bike, allowing the cyclist to alternately exercise both sides of the upper musculature, or two rods, one on each side of the bike, can be attached so that simultaneously exercise both sides of the upper musculature with the bicycle. [0010] The rod is retained on the pedal, but still maintains a degree of freedom of movement, being able to rotate freely around the longitudinal axis of said pedal. Thus, when the rod is transferring force to the pedal, the cyclist maintains it in a substantially vertical position, anatomically suitable for the effort made by the arm. When the cyclist wants to stop using the rod, simply release it. The force of gravity will cause this rod to tip to an inclined position, in which it does not hinder the movement of the bicycle or the cyclist's pedaling, and at that moment another item of the proposed set comes into action, a flexible support rope that is attached to the stem and to the bicycle seat, suitable for supporting and maintaining the stem in that inclined position.
[0011 ] Por fim, o conjunto proposto ainda compreende meios para fixar a haste ao quadro da bicicleta. No momento em que é desejado remover a haste da bicicleta, basta desacoplar a extremidade do pedal, retrair seu comprimento e fixá-la para transporte, mantendo-a sempre disponível para quando for novamente necessária. [0011] Finally, the proposed set still comprises means to fix the rod to the frame of the bicycle. When it is desired to remove the bicycle stem, simply detach the end of the pedal, retract its length and fix it for transportation, keeping it always available for when it is needed again.
[0012] Em resumo, o modelo de utilidade revelado no presente relatório descritivo apresenta uma série de vantagens em relação ao estado da técnica: permite que uma bicicleta comum seja utilizada para exercitar a musculatura superior do usuário, com óbvios ganhos para a saúde, já que exercita braços, ombros e costas e, ainda, propicia maior queima de calorias; aumenta a propulsão da bicicleta; permite descanso das pernas do ciclista, sem perda de propulsão; é passível de instalação manual, sem o uso de ferramentas; pode ser instalado em qualquer modelo de bicicleta e em qualquer lado da bicicleta; é ajustável para pessoas de diferentes alturas; apresenta fácil transporte quando desmontado e é fácil de acessar, já que está fixado à própria bicicleta. [0012] In summary, the utility model revealed in the present specification presents a number of advantages in relation to the state of the art: it allows a common bicycle to be used to exercise the user's upper musculature, with obvious health gains, already who exercises arms, shoulders and back and also provides greater calorie burning; increases the propulsion of the bicycle; allows rest of the cyclist's legs, without loss of propulsion; it is capable of manual installation, without the use of tools; can be installed on any model of bicycle and on any side of the bicycle; it is adjustable for people of different heights; easy to transport when disassembled and easy to access, since it is attached to the bicycle itself.

Descrição detalhada do modelo Detailed model description
[0026] Conforme pode ser visualizado nas figuras anexas em geral e na figura 1 em particular, o conjunto para exercitar a musculatura superior em bicicleta compreende uma haste retrátil (1 ), dotada em uma extremidade de uma empunhadura (2) e na outra extremidade de meios de fixação (3) a um pedal especial (4) (que deve substituir o pedal original da bicicleta), compreendendo, ainda, um fio flexível de sustentação (5) com meios para a fixação (6) à haste (1 ) e a bicicleta (7), bem como meios de fixação para transporte (8). [0026] As can be seen in the attached figures in general and in Figure 1 in particular, the set for exercising the upper muscles on a bicycle comprises a retractable rod (1), provided at one end of a handle (2) and at the other end of fastening means (3) to a pedal special (4) (which must replace the original bicycle pedal), also comprising a flexible support wire (5) with means for fixing (6) to the rod (1) and the bicycle (7), as well as means fastening for transport (8).
[0027] A haste retrátil (1 ) apresenta preferencialmente uma estrutura telescópica, constituída por duas peças tubulares (9 e 10), preferencialmente cilíndricas (mas podendo adotar outras formas de seções) de diferentes dimensões, adequados para que uma possa ser montada de forma deslizante dentro da outra. Na concretização preferencial do modelo, a peça tubular interna (9) apresenta uma multiplicidade de furos longitudinalmente alinhados (11 ) formando uma gradação, que permite ajuste do comprimento através da introdução de uma rosca de aperto com manipulo (12) em um dos furos (11 ), de modo a comprimir a peça tubular externa (10) e obter fixação por interferência. Será evidente para um técnico no assunto que os furos (11 ) podem estar dispostos tanto na peça tubular (9) como na peça externa (10) sem alterar o funcionamento da haste. [0027] The retractable rod (1) preferably presents a telescopic structure, consisting of two tubular parts (9 and 10), preferably cylindrical (but being able to adopt other shapes of sections) of different dimensions, suitable so that one can be assembled in a way sliding into the other. In the preferred embodiment of the model, the inner tubular part (9) has a multiplicity of longitudinally aligned holes (11) forming a gradation, which allows adjustment of the length by introducing a clamping thread with handle (12) in one of the holes ( 11), in order to compress the external tubular part (10) and obtain fixation by interference. It will be apparent to a person skilled in the art that the holes (11) can be arranged in both the tubular part (9) and the outer part (10) without altering the operation of the rod.
[0028] Em concretização alternativa representada nas figuras 4 e 5, as peças tubulares podem ser dotadas de outros meios de fixação mútua, como pinos retráteis com molas (13) operacionalmente ligados a ditos furos (11 ). [0028] In an alternative embodiment represented in figures 4 and 5, the tubular parts can be provided with other means of mutual fixation, such as retractable pins with springs (13) operationally connected to said holes (11).
[0029] Na concretização preferencial do modelo, a empunhadura (2) apresenta formato anatômico para receber ambas as mãos do usuário, uma vez que a haste (1 ) foi concebida para fixação em qualquer dos lados da bicicleta (7), sendo formada por um anel fechado (14) com reentrâncias (15) para os dedos (representada na maioria das figuras), entretanto, pode ter também a forma de uma barra horizontal (16) (como ilustrado pela figura 3). [0029] In the preferred embodiment of the model, the handle (2) has an anatomical shape to receive both hands of the user, since the rod (1) was designed to be fixed on either side of the bicycle (7), being formed by a closed ring (14) with recesses (15) for the fingers (shown in most of the figures), however, can also be in the form of a horizontal bar (16) (as illustrated by figure 3).
[0030] A extremidade de fixação da haste (1 ) ao pedal (4) é dotada de uma abertura onde é montado um rolamento (17), que coopera com o eixo (18) do pedal (4), de modo que a haste (1 ) possa girar livremente em torno desse eixo. [0030] The end of fixing the rod (1) to the pedal (4) is provided with an opening where a bearing (17) is mounted, which cooperates with the axis (18) of the pedal (4), so that the rod (1) can rotate freely around that axis.
[0031 ] Em uma concretização preferencial do modelo (representada nas figuras 6 e 7), o eixo (18) é dotado de rosca interna (19), que permite a fixação da haste (1 ) por parafuso (20) e separador (21 ). Nesse caso, a cabeça do parafuso (20) é recoberta com um manipulo (22) que permite rosqueamento manual sem o uso de ferramentas adicionais. [0032] Outra concretização do modelo (representada na figura 8) prevê que o eixo (18) apresente um prolongamento externo (23) com rosca externa (24). Dito prolongamento (23) é introduzido no rolamento (17) da extremidade de fixação da haste (1 ), de maneira que a rosca externa (24) atravessa dita extremidade e fica disponível do outro lado para fixação por borboleta (25). Dita borboleta (25) é preferencialmente dotada de formato anatômico, com reentrâncias próprias para os dedos do usuário, de maneira a também permitir fixação sem o uso de ferramentas adicionais. [0031] In a preferred embodiment of the model (shown in figures 6 and 7), the shaft (18) is equipped with an internal thread (19), which allows the fixation of the rod (1) by screw (20) and separator (21 ). In this case, the screw head (20) is covered with a handle (22) that allows manual threading without the use of additional tools. [0032] Another embodiment of the model (shown in figure 8) provides that the shaft (18) has an external extension (23) with external thread (24). Said extension (23) is introduced in the bearing (17) of the rod fixation end (1), so that the external thread (24) crosses said end and is available on the other side for fixation by butterfly (25). Said butterfly (25) is preferably provided with an anatomical shape, with indentations suitable for the user's fingers, in order to also allow fixation without the use of additional tools.
[0033] Como representado nas figuras 9 e 10, qualquer que seja a modalidade de fixação, quando a haste (1 ) é acoplada ao pedal (4) pode girar livremente em torno do eixo deste, o que permite ao usuário encontrar a posição mais adequada para empurrar (figura 9) e puxar (figura 10) dito pedal (4), aumentando a impulsão e exercitando a musculatura das costas, do peito e dos braços. [0033] As shown in figures 9 and 10, whatever the fixation mode, when the rod (1) is coupled to the pedal (4) it can rotate freely around its axis, which allows the user to find the most suitable for pushing (figure 9) and pulling (figure 10) said pedal (4), increasing the thrust and exercising the muscles of the back, chest and arms.
[0034] Quando o usuário deixa de usar a haste (1 ), esta é solta e inclina por ação da gravidade, sendo mantida nessa posição por um fio flexível (5) provido em suas extremidades de mosquetões (6) para conectar a haste (1 ) com o assento da bicicleta (como pode ser visualizado na figura 1 1 ). [0034] When the user stops using the rod (1), it is loosened and tilted by gravity, being held in that position by a flexible wire (5) provided at the ends of carabiners (6) to connect the rod ( 1) with the bicycle seat (as shown in figure 1 1).
[0035] Os meios de fixação para transporte (8) são preferencialmente constituídos por uma fita com velcro (26) para fixação da haste (1 ) retraída, quando esta é separada do pedal (4) para transporte, tal como ilustrado na figura 12. Também é evidente para qualquer técnico no assunto que a fita com velcro (26) pode estar disposta tanto na haste (1 ) (como representado nos desenhos anexos), como no quadro da bicicleta (7) e que os meios (8) podem ser implementados por outros dispositivos conhecidos, como uma corrente com cadeado. [0035] The fixing means for transport (8) are preferably constituted by a tape with velcro (26) for fixing the retracted rod (1), when it is separated from the pedal (4) for transport, as illustrated in figure 12 It is also evident to any person skilled in the art that the velcro strap (26) can be arranged both on the stem (1) (as shown in the attached drawings) and on the bicycle frame (7) and that the means (8) can be implemented by other known devices, such as a padlock chain.
[0036] Tratou-se no presente relatório descritivo de um modelo de utilidade dotado de aplicação industrial, novidade, melhoria funcional e ato inventivo, todos os requisitos determinados por lei para receber a patente pleiteada. [0036] This specification describes a utility model with industrial application, novelty, functional improvement and inventive act, all the requirements determined by law to receive the patent applied for.
