Abstract

The portable ergometric step with lateral bars and software coupled to the pedometer (hardware) is a portable device comprising a base made of ethyl vinyl acetate (EVA) which is at most 80 cm wide, 30 cm deep and 30 cm high, with holes in the upper part, in which two lateral bars are fitted to support the user. The step can have three other alternative heights, 15, 20, 25 and 30 cm, by using EVA plates of different colours, with a chamfered front portion to reduce the risk of tripping the user, the plates being fitted to the base by means of a system of "key-and-lock", in order to reduce the risk of the plates slipping during the exercise. These plates can be placed one by one, depending on the applied exercise protocol, and according to the step heights most commonly described in the literature. A number of strain gauges identifies the load of the weight of each lower limb separately and is coupled to the top part of the step. Four wheels are provided on one of the side faces of the base of the step to ensure portability. In this situation, the handles of the lateral support are removed and attached to the front and rear faces of the base, making transport easier. A LED screen is arranged in the top face of the step, opposite the base, and records the patient's performance evaluated by two presence sensors that are attached to the upper part of the base and identify the number of times the user steps on the step. The system comprises a light and sound trigger to identify the beginning of the test, and the evaluator has the option of entering the type of stepper protocol that will be used (self-timed or externally timed). In addition, the sensors identify the total duration of the test, the step up and step down times (ms), the total time/cycle, the number of step ups and step downs per minute. This information is recorded in hardware and transferred to a computer over an USB input/output. The data are analysed by specific software created for that purpose and capable of including evaluator and user data and generating a performance report containing, besides the data obtained by the integrated presence sensors and weight load sensors for each lower limb, other patient variables which can be obtained by calculation carried out by the software, such as: 1) VO2max (ml.min-1. kg-1) = Whor + Wvert; Whor = 0.35 x steps min-1, Wvert = a*steps min-1*step height (m).

Description

"DISPOSIÇÃO CONSTRUTIVA INTRODUZIDA EM DEGRAU ERGOMÉTRICO PORTÁTIL COM REGISTRADOR DE DESEMPENHO E SOFTWARE"  "CONSTRUCTIVE PROVISION INTRODUCED IN PORTABLE ERGOMETRIC DEGREES WITH PERFORMANCE RECORDER AND SOFTWARE"
CAMPO DE APLICAÇÃO  APPLICATION FIELD
[001] O' degrau ergométrico portátil com barras laterais e software acoplado com o contador de passos (hardware) trata-se de instrumento portátil constituído de uma base de etileno acetato de viníla (EVA) com 80 cm de largura, 30 cm de profundidade e 30 cm de altura (no máximo) com orifícios na parte superior onde se encaixam duas barras laterais para apoio dos usuários. O degrau pode ter outras três alturas alternativas 15, 20, 25 e 30 cm por meio do uso de placas de EVA de cores diferentes, com a porção anterior chanfrada para redução de risco de o usuário tropeçar, que são encaixadas na base por meio de sistema "chave-fechadura" para diminuir riscos de deslizamento das mesmas durante o exercício. Taís placas podem ser colocadas uma a uma, dependendo do protocolo de exercício aplicado, de acordo com os mais descritos na literatura. Na porção superior da última placa adicionada, será acoplado um conjunto de células de carga/ strain gages para avaliação da descarga de peso de cada um dos membros inferiores do usuário. O software acoplado ao produto tem funcionalidades para gerenciamento de pacientes, visitas e protocolos de atendimento. Os dados coletados pelo degrau são processados pelo software gerando relatórios após o processamento dos dados. FUNDAMENTOS DO MODELO [001] The portable step ergometer with side bars and software coupled with the step counter (hardware) is a portable instrument consisting of an 80 cm wide, 30 cm deep ethylene vinyl acetate (EVA) base and 30 cm high (maximum) with holes in the top where two side bars fit to support the users.

In the upper portion of the last added plate, a set of load cells / strain gages will be coupled to evaluate the weight discharge of each of the user's lower limbs. The software attached to the product has functionality for patient management, visits and care protocols. The data collected by the rung is processed by the software generating reports after processing the data. MODEL GROUNDS
[002] Na fase de idealização do protótipo, foi utilizado um banco portátil de madeira com 60cm de largura, 40cm de profundidade e 15cm de altura, sem apoio para mãos do usuário. Ele é revestido com uma placa de etileno acetato de vinila (EVA) para reduzir o risco de deslizamento durante a atividade de subir e descer o degrau. Na porção inferior das laterais há pequenas placas de EVA para evitar o deslizamento do equipamento no chão durante a realização do exercício de subir e descer o degrau.  In the design phase of the prototype, a portable wooden bench 60cm wide, 40cm deep and 15cm high was used, without support for the user's hands. It is coated with an ethylene vinyl acetate (EVA) plate to reduce the risk of slipping during step up and down activity. In the lower portion of the sides there are small EVA plates to prevent the equipment from slipping on the floor during the step up and down exercise.
[003] Para identificar o desempenho do usuário, o equipamento comporta um sistema com dois sensores de presença na porção superior das laterais (um à direita e outro à esquerda) que identificam quando o usuário sobe no degrau. Esses sensores são interligados com um visor digital que fica na face lateral do degrau e possibilita ao avaliador acompanhar o desempenho do usuário uma vez que o número no visor registra o número de vezes que ele sobe no degrau ao longo do exercício.  [003] To identify user performance, the equipment features a system with two presence sensors on the upper side (one on the right and one on the left) that identify when the user climbs the step. These sensors are interconnected with a digital display that is on the side of the step and enables the evaluator to track the user's performance as the number on the display records the number of times he climbs the step over the course of the exercise.
[004] O sistema elétrico que faz o registro fica acomodado na região interna do degrau, apoiado na face lateral interna do equipamento. O sistema é alimentado por bateria que pode ser carregada na rede elétrica por meio de uma fonte de energia bivolt.  [004] The electrical system that makes the registration is accommodated in the inner region of the step, supported on the inner side of the equipment. The system is battery powered which can be charged to the mains via a two volt power source.
[005] Na face contra-lateral ao sistema digital, há uma abertura para facilitar a pega do objeto durante o transporte do mesmo.  On the contralateral face of the digital system, there is an opening to facilitate the grip of the object during its transportation.
[006] Após a aplicação desse protótipo em população de 20 a 45 anos de peso normal e apresentando obesidade, aplicando protocolo de exercício de subida e descida no degrau com cadência livre de seis minutos, percebemos algumas necessidades como: material mais leve para permitir portabilidade; superfície anti-derrapante na base inteira do degrau para melhorar a segurança; maior largura do degrau devido a usuários com maior circunferência de quadril e consequente deslocamento do centro de gravidade; apoio para as mãos para usuários com déficit de equilíbrio; hardware capaz de permitir inclusão de diferentes protocolos de exercício para avaliação física e registro de dados de desempenho; além de software para tratamento dos dados registrados e seguimento da evolução do avaliado por meio de relatórios de desempenho físico. [006] After application of this prototype in population from 20 to 45 years old with normal weight and obesity, applying the up and down exercise protocol on the step with free cadence of six minutes, we noticed some needs as: lighter material to allow portability; non-slip surface on the entire base of the step to improve safety; greater step width due to users with greater hip circumference and consequent displacement of the center of gravity; hand rest for users with balance deficit; hardware capable of including different exercise protocols for physical assessment and recording of performance data; In addition to software for processing the recorded data and monitoring the evolution of the evaluated through physical performance reports.
[007] Dessa forma, um novo protótipo foi elaborado para suprir as necessidades levantadas a partir do protótipo anterio .  Thus, a new prototype was elaborated to supply the needs raised from the previous prototype.
DESCRIÇÃO DO ESTADO DA TÉCNICA  DESCRIPTION OF TECHNICAL STATE
[008] O atual estado da técnica no que diz respeito a equipamentos que realizam a avaliação de capacidade de execução de atividade física abrange modelos como esteiras rolante e bicicletas ergométricas, além de degraus (steps). Os dois primeiros aparecem com alto grau de evolução tecnológica e diversidade de materiais, modelos e funções. O último, a partir das buscas realizadas, não apresenta o mesmo grau de evolução, ficando restrito a soluções de baixo custo e adaptações para uso laboratorial ou mesmo em academias de ginástica e centros de reabilitação. Os modelos de degrau, portanto, não apresentam sistemas de aquisição e tratamento de sinais obtidos durante seu uso e apresentam pouca segurança. [008] The current state of the art for equipment performing physical activity assessment includes models such as treadmills and stationary bicycles, as well as steps. The first two appear with a high degree of technological evolution and diversity of materials, models and functions. The latter, from the searches performed, does not show the same degree of evolution, being restricted to low cost solutions and adaptations for laboratory use or even in gyms and rehabilitation centers. The step models, therefore, they do not have signal acquisition and treatment systems obtained during their use and present little safety.

Esse produto foi criado com o objetivo de ser utilizado para exercícios de aquecimento, alongamento e flexibilidade diferentemente de nossa proposta que é realizar exercícios de subir e descer o degrau, de forma a avaliar a capacidade física do indivíduo e/ou propor exercício de treinamento funcional. Ambos apresentam materiais antideslizantes para aumentar a segurança do usuário e sistema de encaixe para aumento da altura da plataforma. O nosso produto adiciona a vantagem das barras laterais removíveis para suporte do usuário, caso este sinta necessidade. No entanto, a patente anterior não apresenta qualquer sistema de aquisição de desempenho e tratamento desses dados com software específico, como na nossa proposta.  [009] By searching for priority, four patents were found that demonstrate the current state of the art. The first of these is Brazilian (PI number 9301865, classification A63B 23/00) and is entitled "Exercise Platform". This product was created with the purpose of being used for warm-up, stretching and flexibility exercises unlike our proposal to perform step up and down exercises, in order to evaluate the individual's physical capacity and / or propose functional training exercise. . Both feature non-slip materials for increased user safety and a platform height-increasing docking system. Our product adds the advantage of removable sidebars for user support should you feel the need. However, the previous patent does not provide any performance acquisition system and treatment of this data with specific software, as in our proposal.
[0010] A segunda, também brasileira (número MU [0010] The second, also Brazilian (MU number)
8301951-0, classificação A63B 23/04), é intitulada "Disposição introduzida em simulador de degrau". Esse produto tem por objetivo garantir estabilização total no momento do degrau receber os esforços dos usuários. Essa preocupação também esteve presente na configuração de nosso produto ao optarmos pelo esquema de encaixe "chave-fechadura" das plataformas que aliam altura ao degrau. A superfície inferior antiderrapante está presente nos dois produtos. Ainda no quesito segurança, o nosso produto conta com barras laterais removíveis para suporte do usuário, caso este sinta necessidade. Porém, em nossa proposta, houve ainda a preocupação com a leveza do material utilizado na confecção do produto (EVA) para conferir portabilidade, sendo que o outro produto é feito de peças injetadas em plástico rígido. Além disso, essa patente anterior não apresenta qualquer sistema de aquisição de desempenho e tratamento desses dados com software específico, como na nossa proposta. 8301951-0, A63B classification 23/04), is entitled "Step simulator arrangement". This product aims to ensure full stabilization at the time the step receives the efforts of users. This concern was also present in the configuration of our product when we opted for the "lock-key" fitting scheme of platforms that combine height with step. The bottom surface non-slip is present in both products. Still in terms of safety, our product has removable sidebars for user support if you feel the need. However, in our proposal, there was also concern about the lightness of the material used in the manufacture of the product (EVA) to confer portability, and the other product is made of parts injected in rigid plastic. Furthermore, this earlier patent does not provide any performance acquisition system and treatment of this data with specific software, as in our proposal.
[0011] A terceira é japonesa (número 2008104701, classificação A63B 23/04) e é intitulada "Máquina para treinar membros inferiores". Esse modelo possui barras laterais como o nosso produto, porém elas servem para apoio durante o exercício de depositar o peso em um membro inferior de forma a "apertar a plataforma unipodal" e alternar com o lado contralateral em uma plataforma independente ipsilateral. A força realizada é identificada e então, ao terminar o movimento, uma luz se acende indicando que é possível alternar o lado. Há uma plataforma de força em cada uma das plataformas abaixo de cada membro inferior com o objetivo de identificar o final da força exercida para o motor iniciar a subida da plataforma contralateral. A plataforma de força de nosso produto tem objetivo diferente: ela detecta se há diferença ou não da força exercida por cada membro inferior no movimento de subida e descida no degrau, item importante para avaliar e treinar usuários que apresentem lesão nervosa ou musculoesquelética unilateral, por exemplo. Em nosso produto, há duas plataformas independentes, que ficam no mesmo plano, com possibilidade de registro da distribuição de peso de cada membro inferior independente. 0 movimento a ser realizado é de subir e descer na plataforma (ou degrau) , sendo que o movimento parte do solo em direção ao degrau e deste, em direção ao solo. Portanto, há um deslocamento vertical e horizontal no exercício proposto. O software embarcado ao produto fará o cálculo do trabalho realizado pelo usuário baseado também nesses deslocamentos. The third is Japanese (number 2008104701, classification A63B 23/04) and is entitled "Machine for training lower limbs". This model has sidebars like our product, but they serve as support during the exercise of depositing the weight on a lower limb in order to "tighten the unipodal platform" and alternate with the contralateral side on an independent ipsilateral platform. The realized force is identified and then, when the movement is finished, a light comes on indicating that it is possible to alternate the side. There is a force platform on each of the platforms below each lower limb to identify the end of the force exerted by the engine to start the contralateral platform ascent. The force platform of our product has a different purpose: it detects whether or not there is a difference in the force exerted by each lower limb in the up and down movement of the step, an important item to evaluate and train users with unilateral nerve or musculoskeletal injury, for example. In our product, there are two independent platforms, which are in the same plane, with the possibility of recording the weight distribution of each independent lower limb. The movement to be performed is to go up and down on the platform (or step), and the movement starts from the ground towards the step and from it, towards the ground. Therefore, there is a vertical and horizontal displacement in the proposed exercise. The software embedded in the product will calculate the work done by the user based also on these offsets.
[0012] A quarta e quinta patentes são norte- americanas, A primeira delas é intitulada: "Dispositivo do tipo step para prática de ginástica ínterativa" (número 2010/0216598, classificação A63B 26/00) . Apesar de o uso do step da patente referida ser para treino de ginástica, que também pode ser o caso de uso de nosso produto, ele apresenta integração com sistema interativo que envolve sons e imagens. Tais recursos, apesar de interessantes, encarecem o produto final e tornam a realização do exercício neste equipamento limitado a pessoas que compreendam tal nível de tecnologia. A utilização de nosso degrau pode ser feita em ambientes com pouco espaço físico disponível e sem a presença obrigatória de um computador para análise dos dados, uma vez que os dados de desempenho ficam armazenados em cartão SD para possível análise posterior. Dessa forma, já que nosso equipamento preza pela portabilidade, seu uso pode ser estendido para ambientes onde a alta tecnologia não está disponível, como centros comunitários ou unidades de saúde da família em periferias das cidades, por exemplo. [0012] The fourth and fifth patents are North American patents. The first of these is entitled: "Step-type device for inactive gymnastics practice" (number 2010/0216598, classification A63B 26/00). Although the use of the patent step referred to is for gym training, which may also be the use case of our product, it has integration with interactive system that involves sounds and images. Such features, while interesting, make the end product more expensive and make exercising on this equipment limited to people who understand such a level of technology. Our step can be used in environments with limited available physical space and without the obligatory presence of a computer for data analysis, since the performance data is stored in SD card for possible further analysis. Therefore, as our equipment values portability, its use can be extended to environments where high technology is not available, such as community centers or family health facilities. outskirts of cities, for example.
[0013] A segunda patente é intitulada "Step para exercício aeróbico agregado" (número 2003/0186786, classificação A63B 22/04). Trata-se de um degrau em formato de caixote, com alça em uma das laterais e rodízios na lateral oposta para facilitar a portabilidade; essas duas características que facilitam a portabilidade são semelhantes às do nosso produto. Ao abrir a tampa desse "caixote", é possível verificar um espaço em que podem ser acomodados equipamentos que podem auxiliar a prática de exercícios durante o exercício usual de subir e descer o degrau, como halteres para membros superiores, caneleiras, corda, entre outros. Em relação ao nosso produto, ele apresenta a desvantagem de não possuir possibilidade de alturas diferentes do degrau, que possibilita a avaliação e/ou o treino em populações de alturas diferentes ou que necessitem aumento da carga de trabalho. Além disso, também não possui sistema de aquisição de desempenho e tratamento desses dados com software específico.  The second patent is entitled "Step for Aggregate Aerobic Exercise" (number 2003/0186786, classification A63B 22/04). This is a crate-shaped step with handle on one side and casters on the opposite side for easy portability; These two features that facilitate portability are similar to those of our product. By opening the lid of this "crate", it is possible to see a space in which equipment can be accommodated that can assist the practice of exercises during the usual exercise of up and down the step, such as dumbbells for the upper limbs, shin guards, rope, among others. . Regarding our product, it has the disadvantage that it has no possibility of different heights of the step, which allows the evaluation and / or training in populations of different heights or that require increased workload. In addition, it does not have a system for performance acquisition and treatment of this data with specific software.
[0014] Na busca de anterioridade, foram ainda encontrados outros documentos considerados altamente relevantes por apresentarem características parcialmente similares à descrição do nosso produto. Foram eles:  In the search for priority, other documents considered highly relevant were found because they have characteristics partially similar to the description of our product. They were:
[0015] 1) Origem: Estados Unidos, Número [0015] 1) Origin: United States, Number
2006/0199703, classificação A63B 22/04. Esse produto apresenta barras laterais para apoio do usuário e recursos para portabilidade, como no nosso produto; no entanto o movimento simulado, além da subida em degrau único, é a subida em escada, diferente de nossa proposta. Ele comporta uma série de parafusos e ajustes em sua montagem/ desmontagem que pode dificultar ao usuário dispô-lo para uso e aumentar a chance de manutenção devido a possíveis desalinhamentos na montagem. O equipamento não possui sistema de aquisição de desempenho e tratamento desses dados com software específico como na nossa proposta. 2006/0199703, A63B classification 22/04. This product features sidebars for user support and portability features, as in our product; however the simulated movement, besides the single step climb, is the Climbing, different from our proposal. It has a number of screws and adjustments to its assembly / disassembly that can make it difficult for the user to arrange it for use and increase the chance of maintenance due to possible misalignment in the assembly. The equipment does not have performance acquisition system and treatment of this data with specific software as in our proposal.
[0016] 2} Origem: Estados Unidos, Número 5.354.247, classificação A63B 5/00. Tal invento é composto de vários degraus individuais, de tamanhos diferentes ou similares, que podem ser dispostos formando uma escada ou ainda outras conformações que o usuário deseje, de acordo com o objetivo do exercício a ser realizado. Trata-se de um equipamento de uso prático para montagem, no entanto, a quantidade de degraus necessários pode tornar a portabilidade desconfortável. Além disso, esse equipamento não possui barras laterais para estabilização do usuário e nem tecnologia embarcada para análise do desempenho no exercício, como há em nossa proposta.  [0016] 2} Origin: United States, Number 5,354,247, A63B classification 5/00. Such an invention is composed of several individual steps, of different or similar sizes, which may be arranged forming a ladder or other conformations desired by the user, according to the purpose of the exercise to be performed. This is a handy mounting device, however, the amount of steps required can make portability uncomfortable. In addition, this equipment does not have sidebars for user stabilization or embedded technology for exercise performance analysis, as there is in our proposal.
[0017] 3) Origem: Estados Unidos, Número 4.216.956, classificação A63B 23/04. Esse equipamento, como o próprio título informa, é uma máquina de corrida. Há uma plataforma, onde o indivíduo simula a corrida ou a caminhada, com um visor na parte frontal no qual é possível ver o desempenho do usuário - nesse caso, o número de passadas e o tempo gasto. Assim como em nossa proposta, há a possibilidade de registro do desempenho do usuário. No entanto, não há um software específico para análise e tratamento desses sinais. Outra diferença com o nosso invento é que o movimento simulado não é o mesmo: nessa patente, o indivíduo simula a caminhada ou corrida e, em nossa proposta, o indivíduo simula subir e descer degrau. Portanto, o objetivo dos dois equipamentos é diferente, dada a especificidade do exercício realizado. [0017] 3) Origin: United States, Number 4,216,956, classification A63B 23/04. This equipment, as the title itself states, is a racing machine. There is a platform where the individual simulates running or walking, with a display on the front where you can see the user's performance - in this case, the number of strides and time spent. As with our proposal, there is the possibility of recording user performance. However, there is no specific software for analyzing and treating these signs. Other The difference with our invention is that the simulated movement is not the same: in this patent, the individual simulates walking or running and, in our proposal, the individual simulates climbing and descending a step. Therefore, the purpose of the two equipment is different, given the specificity of the exercise performed.
[0018] 4) Origem: Estados Unidos, Número 4.477.070, classificação A63B 23/04. Esse invento foi criado com o objetivo de registrar o desempenho em um simulador de corrida que pode ser usado em ambiente fechado. Trata-se de uma plataforma formada por uma espécie de cama elástica (ou trampolim) onde o indivíduo faz o movimento de correr e há um suporte anterior (com suporte de mão) que deve ser fixo na parede. Essa característica limita a portabilidade, um dos quesitos interessantes de nossa proposta. Tal equipamento difere também do nosso pelo movimento requerido do usuário e pela incapacidade de registrar seu desempenho.  [0018] 4) Origin: United States, Number 4,477,070, classification A63B 23/04. This invention was created for the purpose of recording performance in a race simulator that can be used indoors. It is a platform formed by a kind of trampoline (or trampoline) where the individual makes the movement of running and there is an anterior support (with hand support) that must be fixed to the wall. This feature limits portability, one of the interesting points of our proposal. Such equipment also differs from ours by the user's required movement and inability to record its performance.
[0019] 5) Origem: Estados Unidos, Número 3.735.101, classificação G06M 3/02. Esse equipamento tem o objetivo de estimular e supervisionar pacientes na realização de exercícios de fisioterapia. Há quatro partes distintas: a primeira parte consta de um painel iluminado para estímulo visual e sonoro "exercite-se agora"; a segunda, de um sensor capaz de registrar o tempo e/ ou a quantidade de exercício realizado; a terceira desliga a primeira quando o exercício já foi realizado; e a quarta reinicia o estímulo após um intervalo pré-determinado . Assim, o fato de perceber e registrar o desempenho do usuário é semelhante ao existente em nosso produto. No entanto, tal equipamento não é direcionado para o exercício de degrau, como no nosso caso. Ainda, em nosso produto, há a possibilidade de o usuário selecionar se fará um protocolo auto cadenciado e tempo- limitado (nesse caso, o equipamento emite sinal luminoso ao final do tempo selecionado) ou com cadência determinada por sinal sonoro e/ou luminoso e ainda oferece um software para análise dos dados de desempenho. 5) Origin: United States, Number 3,735,101, G06M classification 3/02. This equipment aims to stimulate and supervise patients in performing physical therapy exercises. There are four distinct parts: the first part consists of a lighted panel for "exercise now" visual and audible stimulation; the second, a sensor capable of recording the time and / or the amount of exercise performed; the third turns off the first when the exercise has already been performed; and the fourth restarts the stimulus after a predetermined interval. Thus, noticing and recording user performance is similar to that in our product. However, such equipment is not directed to the step exercise, as in our case. Also, in our product, there is the possibility for the user to select whether to make a self-paced and time-limited protocol (in this case, the equipment will emit a light signal at the end of the selected time) or with a cadence determined by a sound and / or light signal. It also offers software for analyzing performance data.
[0020] 6) Origem: Estados Unidos, Número [0020] 6) Origin: United States, Number
2013/0344926, classificação A63F 13/00. Trata-se de uma plataforma para a prática de ginástica interativa, ou seja, há associação entre os sensores da plataforma e as imagens e o som que ensinam e/ou estimulam o usuário na prática de exercício físico. A integração dos sinais é feita no sentido de verificar a execução dos movimentos em relação a ultrapassar os obstáculos colocados ao usuário pelas imagens fornecidas . Nosso invento não tem esse intuito de entretenimento como o equipamento citado. Além disso, o desempenho do usuário dessa patente não passará por tratamento em software específico que fornecerá dados de potência de trabalho (vertical e horizontal) , gráficos de desempenho, evolução em relação à avaliação inicial e após o treinamento, como acontece em nossa proposta. 2013/0344926, A63F 13/00 rating. It is a platform for the practice of interactive gymnastics, that is, there is an association between the platform sensors and the images and sound that teach and / or stimulate the user in the practice of physical exercise.

Our invention is not intended for entertainment as the equipment mentioned. In addition, the user performance of this patent will not be treated with specific software that will provide working power data (vertical and horizontal), performance graphs, evolution from the initial evaluation and after training, as in our proposal.
[0021] 7) Origem: Estados Unidos, Número [0021] 7) Origin: United States, Number
2001/0044362, classificação A63B 71/00. Esse sistema monitora o impacto do estresse ou das forças de aceleração em um usuário durante a realização de atividade física e pode ser adicionado em um equipamento para realização de exercício. Esse aparato se assemelha às placas de forças colocadas na porção superior de nosso degrau ergométrico. No entanto, as placas de força de nossa proposta medem individualmente as forças exercidas por cada um dos membros inferiores, sendo um eficiente método para avaliar e treinar indivíduos com limitações neurológicas ou musculoesqueléticas unilaterais, por exemplo, durante o exercício de subir e descer o degrau. Com as respostas das forças exercidas por cada membro, o indivíduo é capaz de ajustar e treinar a descarga de peso igualitária entre os membros no momento de usar o degrau. 2001/0044362, A63B classification 71/00. This system monitors the impact of stress or acceleration forces on a user while performing physical activity and can be added to exercise equipment. This apparatus resembles the force plates placed on the upper portion of our exercise step. However, the strength plates of our proposal individually measure the forces exerted by each of the lower limbs, and are an efficient method for assessing and training individuals with unilateral neurological or musculoskeletal limitations, for example, during the step up and down exercise. . With the responses of the forces exerted by each limb, the individual is able to adjust and train the equal weight discharge between the limbs when using the step.
[0022] 8) Origem: Japão, Número 2004290691A, classificação A63B 23/04. Esse invento compreende um degrau para realizar exercício e ainda um sistema de aquisição e transferência de dados de desempenho do usuário para um celular ou similar. Essa patente envolve diversas configurações de produto com essa mesma intenção. No entanto, diferentemente de nosso produto, não há um software capaz de reunir todas as informações que o nosso faz, como: dados demográficos e antropométricos do usuário, medicações, dados de testes sequenciais realizados permitindo gerar gráficos de evolução do desempenho do paciente, dados de contagem do tempo de subida e tempo de descida em ms, tempo de pausa, cálculo do trabalho vertical e horizontal realizado bem como o consumo de oxigénio inferido por meio dessas duas últimas variáveis, dentre outras. 8) Origin: Japan, Number 2004290691A, classification A63B 23/04. This invention comprises a step for performing exercise and a user performance data acquisition and transfer system for a mobile phone or the like. This patent involves several product configurations with the same intent. However, unlike our product, there is no software that can gather all the information that we do, such as: demographic and anthropometric user data, medications, sequential test data performed allowing graphs of patient performance evolution, data of rise time count and fall time in ms, rest time, calculation of the vertical and horizontal work performed as well as the oxygen consumption inferred through these last two variables, among others.
[0023] 9) Origem: Grã-Bretanha, Número 2399767A, classificação A63B 24/00. Trata-se de um equipamento que integra as informações de um monitor e de uma espécie de tapete onde o usuário realiza o programa de exercício selecionado. Esse tapete é formado por quadrados onde estão posicionados sensores que identificam os movimentos do usuário. Esse equipamento difere do nosso uma vez que o objetivo, além da prática de atividade fisica, é fazer o usuário interagir com o equipamento. Além disso, o equipamento não identifica movimento de subida e descida no degrau, uma vez que o tapete fica disposto no solo em uma altura única. 9) Origin: Great Britain, Number 2399767A, A63B classification 24/00. It is a device that integrates the information of a monitor and a kind of mat where the user performs the exercise program. selected. This mat is formed by squares where sensors are placed that identify the user's movements. This equipment differs from ours in that the goal, besides the practice of physical activity, is to make the user interact with the equipment. In addition, the equipment does not identify up and down movement on the step as the mat is arranged on the floor at a single height.
[0024] 10) Origem: Estados Unidos, Número 4.927.138, classificação A63B 1/00. Esse invento possui uma plataforma de força com barras laterais para estabilização do usuário e tem itens que facilitam a portabilidade, como o nosso invento, apesar de também poder ser fixado. O objetivo é que o paciente faça movimentos de corrida em cima da plataforma ou agachamentos e, a quaisquer esforços desses tipos, sinais eletrônicos monitoram e comunicam ao usuário o esforço despendido no exercício, tendo por base o peso corporal dos usuários. Apesar de também possuir plataforma de força, esse equipamento difere do nosso porque apresenta uma placa única de força (no nosso modelo há uma para cada membro inferior) e o tipo de exercício a ser realizado não é o de subir e descer degrau .  10) Origin: United States, Number 4,927,138, A63B classification 1/00. This invention has a sidebar force platform for user stabilization and has items that facilitate portability, such as our invention, although it can also be fixed. The goal is for the patient to make running movements on the platform or squats and, at any effort of these types, electronic signals monitor and communicate to the user the effort expended in the exercise based on the users' body weight. Although it also has a force platform, this equipment differs from ours because it has a unique force plate (in our model there is one for each lower limb) and the type of exercise to be performed is not to go up and down the step.
[0025] 11) Origem: Estados Unidos, Número 5.584.779, classificação A63B 21/00. Trata-se de um equipamento composto por degraus sequenciais dispostos formato semi-circula . Os degraus desse sistema são conectados internamente a um controlador que emite sinais que indicam ao usuário a sequência de degraus que deve subir, de acordo com as cores dos degraus, formando assim, uma espécie de coreografia durante o exercício. Na porção frontal do equipamento há um visor que mostra ao usuário a contagem dos passos, a taxa de subida/ decida no degrau, as calorias gastas e o tempo de exercício realizado. É possível ainda ao usuário mudar a sequência e a velocidade da "coreografia". Apesar de ter um visor que mostra o desempenho do usuário como em nossa proposta, o nosso equipamento é capaz de oferecer outras medidas que esse não é, como: número de ciclos subida/descida no degrau por min, tempo de subida e tempo de descida no degrau (em ms) , tempo de pausa {em ms) , além do tempo total de exercício. Tais medidas são importantes para análise detalhada da capacidade funcional de indivíduos saudáveis, atletas ou mesmo doentes, para programar um treinamento mais direcionado para seus objetivos. Além do objetivo ser a integração do exercício aeróbio com o lúdico, que não se assemelha ao nosso, o tamanho do equipamento dificulta a portabilidade, um dos requisitos importantes de nosso invento. Ele também não possui barras laterais que adicionam segurança ao usuário e software para visualização e tratamento dos dados de desempenho. 11) Origin: United States, Number 5,584,779, A63B classification 21/00. It is an equipment composed of sequential steps arranged semi-circular format. The steps in this system are internally connected to a controller that gives signals that tell the user which sequence of steps to climb according to the colors. the steps, thus forming a kind of choreography during the exercise. In the front portion of the equipment there is a display that shows the user the step count, the step up / down rate, the calories expended and the exercise time performed. It is also possible for the user to change the sequence and speed of the "choreography". Despite having a display that shows user performance as per our proposal, our equipment is able to offer other measurements than this, such as: number of steps up / down per min, up time and down time on the step (in ms), rest time (in ms), in addition to the total exercise time. Such measures are important for detailed analysis of the functional capacity of healthy individuals, athletes or even patients, to schedule more targeted training for their goals. In addition to the goal of integrating aerobic exercise with play, which does not resemble ours, the size of the equipment makes portability difficult, one of the important requirements of our invention. It also has no sidebars that add user safety and software for viewing and processing performance data.
[0026] 12) Origem: Grã-Bretanha, Número 2448880A, classificação A63B 23/04. Este invento, apesar de bastante semelhanças (sensor de presença, contagem de ciclos subida/descida no degrau, transferência dos dados de desempenho para um computador) com o nosso, não possui barras laterais para segurança do usuário e não conta com requisitos que facilitem a portabilidade, como rodízios, por exemplo. Além disso, ele não possui plataforma de força individualizada para cada membro inferior que permita identificar e treinar a força descarregada por cada membro no exercício de subir e descer o degrau. Outras diferenças são em relação à contagem de passos e detalhamento de tempo de subida e tempo de descida do usuário, que pode ser uma variável importante de avaliação de capacidade funcional. [0026] 12) Origin: Great Britain, Number 2448880A, classification A63B 23/04. This invention, despite quite similarities (presence sensor, step up / down cycle count, transfer of performance data to a computer) with ours, has no user safety sidebars and no requirements that facilitate portability, such as casters, for example. In addition, it does not have an individualized force platform for each lower limb to identify and train the force discharged by each limb in the step up and down exercise. Other differences are in step count and breakdown and breakdown time, which can be an important variable of functional capacity assessment.

The free product search was performed including different databases: Brazilian Institute of Industrial Property (INPI), USPTO, EPO and DERWENT.
[0028] Foram encontrados sete produtos na base INPI, a saber: 1) Aparelho de ginástica, Patente: MU 8601860-4 U2; 2) Aparelho integrado de ginástica e lazer, Patente: PI 0103150-3 A2; 3) Aparelho de ginástica simulador de degrau compacto, Patente: PI 9401513-9 A2; 4) Bicicleta ergométrica c/ degrau acoplado, Patente: MU 7302163-6 U2 5) Degrau para exercícios aeróbicos, Patente: MI 5101190-5; 6) Disposição introduzida em prancha ajustável degrau aeróbico e muscular, Patente: MU 7001287-3 Yl; 7) Degrau para exercícios físicos; Patente: PI 8705594-5 A2. Os equipamentos 1 e 2 são diferentes do nosso protótipo pois não integram sistema de aquisição de desempenho físico por meio de software (número de passos subidos, tempo para realizar os movimentos, descarga de peso dos membros inferiores), e não oferecem diferentes alturas de degrau que beneficia populações de estaturas distintas, nem apresentam apoio nas laterais para maior segurança. O terceiro e quarto produtos, também não integram sistema de aquisição do desempenho dos usuários e itens de segurança e conforto para populações de diferentes estaturas como o nosso. Apesar de serem desmontáveis como nosso produto, são providos de varetas e mecanismos elásticos em sua estrutura, diferentemente de nossa proposta que é de adicionar simplicidade na montagem e utilização de materiais leves, baratos e duráveis. Quanto ao quinto, sexto e sétimo produtos, não foram encontradas descrições no site do Instituto Nacional de Propriedade Industrial suficientes para compararmos tais produtos com o nosso. Seven products were found in the INPI database, namely: 1) Fitness machine, Patent: MU 8601860-4 U2; 2) Integrated gym and leisure apparatus, Patent: PI 0103150-3 A2; 3) Compact step simulator gym apparatus, Patent: PI 9401513-9 A2; 4) Exercise bike with attached step, Patent: MU 7302163-6 U2 5) Aerobic exercise step, Patent: MI 5101190-5; 6) Arrangement introduced in adjustable aerobic and muscular step board, Patent: MU 7001287-3 Yl; 7) Step for physical exercise; Patent: PI 8705594-5 A2. The equipment 1 and 2 are different from our prototype because they do not integrate software physical acquisition system (number of steps climbed, time to perform movements, weight loss of the lower limbs), and do not offer different step heights. which benefits populations of different statures, nor do they have lateral support for greater safety. The third and fourth products, also do not integrate user performance acquisition system and safety and comfort items for populations of different statures like ours. Although they are demountable as our product, they are provided with rods and elastic mechanisms in their structure, unlike our proposal to add simplicity in the assembly and use of lightweight, cheap and durable materials. As for the fifth, sixth and seventh products, no descriptions were found on the National Institute of Industrial Property website sufficient to compare such products with ours.

Unidos, o United States Patent and Trademark Office, encontramos alguns produtos registrados que têm algum grau de semelhança com o nosso produto ou parte dele, como: 1) Method for storing exercise performance of user of exercise device and exercise device, Patente: US 20070016444 Al. Com o nosso software também é possível ao usuário registrar e armazenar dados do desempenho físico, dados de identificação do usuário e do avaliado e é possível acompanhar a evolução do desempenho físico ao longo do tempo. No entanto, ele está dedicado exclusivamente ao ergômetro do degrau; 2) User- programmable computerized console for exercise machines, Patente: Family ID: 27501917, Appl . No.: 07/724,732. No caso de nosso sistema, o microprocessador é dedicado exclusivamente ao ergômetro do degrau, sendo que níveis diferentes de dificuldade podem ser impostos ao avaliado de acordo com o protocolo selecionado (altura do degrau, tempo total de teste, cadência determinada) . No entanto, diferentemente da esteira rolante e da bicicleta ergométrica em que o microprocessador impõe a carga por aumento da velocidade e inclinação programada ou da resistência dos pedais, o aumento de carga em relação ao aumento de altura do degrau é feito previamente pelo avaliador selecionando o protocolo a ser aplicado no hardware; 3) Physical fitness evalution system, Patente: Family ID: 22592370, Appl. No.: 08/188,249. Diferentemente deste sistema, nosso software é dedicado ao uso do ergômetro do degrau.

OBJETIVO DO MODELO [0038] O modelo de utilidade aqui apresentado visa contornar as desvantagens do estado da técnica apresentando melhorias sobre os outros equipamentos (ergômetros) existentes no que tange a custo, portabilidade, manutenção, segurança, ergonomia, desempenho e usabilidade. OBJECTIVE OF THE MODEL The utility model presented here aims to circumvent the disadvantages of the state of the art by presenting improvements over other existing equipment (ergometers) with regard to cost, portability, maintenance, safety, ergonomics, performance and usability.
[0039] Com relação às esteiras e bicicletasWith regard to treadmills and bicycles
(concorrentes indiretos) o modelo se destaca por: (indirect competitors) the model stands out for:
• Portabilidade - facilidade de transporte: o modelo foi projetado para ser leve (material principal: EVA) , fácil desmontagem, fácil movimentação (rodízios incorporados), tamanho compatível com carros pequenos e acessórios como alças e travas;  • Portability - easy to carry: the model is designed to be lightweight (main material: EVA), easy to disassemble, easy to move (built-in casters), size compatible with small cars and accessories such as handles and latches;
Custo: a utilização de materiais comerciais, formas geométricas simples e processo de fabricação racional, com baixa necessidade tecnológica permitiu a configuração de protótipos (e futuramente produtos) com custo muito abaixo que seus concorrentes indiretos ;  Cost: The use of commercial materials, simple geometric shapes and rational manufacturing process, with low technological necessity allowed the prototypes configuration (and future products) with cost much lower than its indirect competitors;
• Manutenção: comparado aos sistemas mecânicos e elementos de máquinas (polias, eixos, correntes, parafusos, esteiras, rodízios, etc.) de bicicletas e esteiras o degrau em desenvolvimento possui manutenção muito simplificada e de baixo custo, sem necessidade de assistência técnica especializada ou manutenção preventiva;  • Maintenance: Compared to mechanical systems and machine elements (pulleys, shafts, chains, bolts, tracks, casters, etc.) of bicycles and treadmills the step under development has very simplified maintenance and low cost, without the need for specialized technical assistance. or preventive maintenance;
• Segurança: o risco de queda ou choque mecânico é consideravelmente inferior se comparado o uso do degrau com relação ao uso de esteiras e bicicletas;  • Safety: The risk of falling or mechanical shock is considerably lower compared to the use of the tread compared to the use of treadmills and bicycles.
• Ergonomia: o projeto contemplou as necessidades dos usuários avaliados e dos avaliadores durante todo o processo de montagem, operação/uso, desmontagem, transporte e manutenção. Dados antropométricos da população brasileira foram utilizados, assim como a busca pela inserção da atividade dos usuários como requisito de projeto. • Ergonomics: the project included the needs of users assessed and evaluators throughout the process of assembly, operation / use, disassembly, transportation and maintenance. Anthropometric data of the Brazilian population were used, as well as the search for the insertion of the users activity as a project requirement.
• Usabilidade: o degrau foi projetado para ser de fácil compreensão e uso por seus usuários (avaliados e avaliadores) , minimizando desconfortos e riscos presentes em esteiras (como velocidade da esteira, pisada em falsa, pisada fora da esteira, medo de queda, entre outras) e bicicletas (choque físico com pedais, desconforto do assento, regulagem incorreta de carga, interferência pela má postura exigida, entre outras). Ademais, subir escadas constitui-se de uma atividade simples, comum das atividades de vida diária (AVDs) . Andar em esteira ou pedalar não são habilidades comuns às AVDs e necessitam treinamento prévio e familiarização. Um teste de exercício em um degrau dispensa a familiarização prévia.  • Usability: The step has been designed to be easy for users to understand and use (users and evaluators), minimizing discomfort and hazards present on treadmills (such as treadmill speed, false step, off-tread, fear of falling, etc.). others) and bicycles (physical shock with pedals, seat discomfort, improper load regulation, interference with the bad posture required, among others). In addition, climbing stairs is a simple activity common to activities of daily living (ADLs). Treadmill or pedaling are not common skills for ADLs and require prior training and familiarization. An exercise test on a step does not require prior familiarization.
[0040] Com relação aos degraus (steps) existentes, o modelo apresenta as seguintes vantagens:  With regard to existing steps, the model has the following advantages:
• Desempenho: a possibilidade de configurar diferentes alturas permite uma melhor avaliação física a partir dos diferentes graus de dificuldade, em populações com diferentes estaturas e nível de atividade física. Possibilidade de avaliar e treinar a distribuição do peso corpóreo pela célula de carga, avaliando obj etivamente a força exercida por cada membro inferior. Tal dispositivo, pode ser útil em pacientes com disfunções neurológicas, com déficit de equilíbrio ou usuários de próteses de membro inferior. Os modelos existentes não possuem esse mecanismo de avaliação e treinamento. • Performance: The ability to configure different heights allows for better physical assessment from different degrees of difficulty in populations with different height and level of physical activity. Possibility to evaluate and train the distribution of body weight by the load cell, objectively evaluating the force exerted by each lower limb. Such a device may be useful in patients with neurological dysfunction with balance deficit or lower limb prosthesis users. Existing models do not have this evaluation and training mechanism.
• Segurança: a presença das barras laterais como elementos de estabilização postural presentes no protótipo, além do material de alta aderência/fixação no solo e baixo risco de choque físico com os elementos do equipamento permite maior segurança e confiança por parte do avaliado na realização da ativxdade física;  • Safety: the presence of the sidebars as postural stabilization elements present in the prototype, in addition to the material of high adhesion / grounding and low risk of physical shock with the equipment elements allows greater safety and confidence on the part of the appraised when performing the procedure. physical activity;
• Manutenção: o material utilizado permite uma manutenção cotidiana de fácil execução e com custo baixo (limpeza de material EVA) e eventuais desgastes também são facilmente corrigidos com a substituição de partes/módulos do produto (chapas de EVA e rodízios, por exemplo) .  • Maintenance: The material used allows easy and cost-effective daily maintenance (cleaning of EVA material) and any wear and tear are also easily corrected by replacing parts / modules of the product (EVA plates and casters, for example).
Praticidade: contagem de passos automática, reduzindo assim a necessidade de mais um examinador para a realização desta tarefa e a possibilidade de erros na análise do desempenho final. Além disso, é possível realizar a contagem do número e tempo de pausas durante a atividade física realizada, índice importante de desempenho físico e usado para estratificação de populações de doentes.  Practicality: Automatic step counting, thus reducing the need for one more examiner to perform this task and the possibility of errors in final performance analysis. In addition, it is possible to count the number and time of breaks during physical activity, an important index of physical performance and used for stratification of patient populations.
Tratamento dos sinais obtidos: possibilidade de realizar diferentes protocolos de testes, de degrau (cadenciados ou não, com diferentes tempos de execução) e de tratamento dos sinais obtidos {tempo de subida, tempo de descida, número de passos, número e tempo de pausas, tempo total de teste, trabalho realizado) permitindo assim obter índices de desempenho por meio de cálculos e, assim, inferir a capacidade de exercício em diferentes populações. Os degraus existentes no mercado não possuem interfaces para tais análises. Treatment of the signals obtained: possibility of performing different test , stepping protocols (cadenced or not, with different execution times) and treatment of the signals obtained (rising time, descending time, number of steps, number and time of breaks) , total test time, work done) allowing thus obtain performance indices through calculations and thus infer exercise capacity in different populations. The existing steps in the market do not have interfaces for such analyzes.
[0041] Por apresentar possibilidade de aquisição de dados de desempenho e integração para processamento desses dados, o modelo proposto terá um custo maior comparado a outros existentes no mercado, visto que nenhum deles apresenta a possibilidade de obtenção de tais medidas de desempenho. Entretanto, quando comparado aos demais ergômetros disponíveis (esteira rolante e bicicleta ergométr.ica) , o mesmo pode ser considerado de baixo custo.  Because it presents the possibility of performance data acquisition and integration for processing such data, the proposed model will have a higher cost compared to others existing in the market, since none of them presents the possibility of obtaining such performance measures. However, when compared to the other available ergometers (treadmill and exercise bike), the same can be considered of low cost.
[0042] A utilização do modelo por indivíduos com amputação unilateral ou bilateral de membro (s) inferior (es) que não estejam utilizando prótese (s) será limitado.  Use of the model by individuals with unilateral or bilateral lower limb amputation not using prosthesis will be limited.

[0055] 0 degrau pode ter quatro alturas alternativas [0055] 0 rung can have four alternate heights
15, 20, 25 e 30 cm por meio do uso de placas de EVA(4) de cores diferentes, com a porção anterior chanfrada para redução de risco do usuário tropeçar, que são encaixadas na base por meio de sistema "chave-fechadura" para diminuir riscos de deslizamento das mesmas durante o exercício. Tais placas (4) podem ser colocadas uma a uma, dependendo do protocolo de exercício escolhido, de acordo com os mais descritos na literatura. 15, 20, 25 and 30 cm using different colored EVA boards (4) with beveled front end for user tripping risk reduction, which are attached to the base by means of a "lock" system to reduce risks of slipping during exercise. Such plates (4) may be placed one by one depending on the exercise protocol chosen, according to the most described in the literature.
[0056] Em uma das faces laterais da base do degrau há quatro rodízios (9) para a portabilidade. Nessa situação, as alças de apoio lateral (7) são removidas e fixadas nas faces anterior e posterior da base, facilitando o transporte conforme a figura 2 referência ( 8 ) .  On one of the side faces of the base of the step are four casters (9) for portability. In this situation, the lateral support straps (7) are removed and attached to the front and rear sides of the base, facilitating the transport according to reference figure 2 (8).
[0057] Na face superior contralateral da base do degrau há um visor em LED (10) que registra o desempenho do paciente avaliado por meio de dois sensores de presença fixados na porção superior (6) que identificam o número de vezes que o usuário subiu no degrau. Esse sistema conta com um disparador luminoso e sonoro (6) para identificação do início do teste e há a possibilidade do avaliador inserir o tipo de protocolo de degrau que realizará (autocadenciado e tempo-limitado ou com cadência determinada por sinal sonoro e/ou luminoso, considerando diferentes tempos de execução do exercício físico) .  On the contralateral upper face of the base of the step is an LED display (10) which records the patient's performance assessed by means of two presence sensors attached to the upper portion (6) that identify the number of times the user has climbed. on the step. This system has a light and sound trigger (6) to identify the start of the test and it is possible for the evaluator to enter the type of step protocol that will perform (self-limited and time-limited or with cadence determined by sound and / or light signal). considering different times of physical exercise).
[0058] Além disso, os sensores ainda identificam o tempo total do teste, tempo de subida e de descida (ms), tempo total/ciclo, número de subidas e descidas/min, tempo de pausa. Tais informações são registradas em um hardware (3) e descarregadas em um computador por meio de um cartão SD. Há ainda a possibilidade de haver a transmissão dos dados obtidos pelo contador de passos por telemetria ao computador e/ou a um aplicativo de smartphone e os dados como número de ciclos subida/descida no degrau serem visualizados simultaneamente na tela desses equipamentos. [0059] Os dados são analisados por meio de um software específico criado para esse fim capaz de comportar dados do avaliador, do usuário e gerar um relatório contendo, além dos dados obtidos pela integração sensores de presença- hardware. Outras variáveis de desempenho do paciente inferidas podem ser obtidas por meio de cálculos no software como: 1) Consumo de oxigénio inferido: V02max (ml .min-1. kg-1) = Whor + Wvert; 2) Trabalho horizontal realizado: W hor = 0,35 x degraus min-1; e 3) Trabalho vertical realizado: vert = a*degraus min-1*altura do degrau (m) . In addition, the sensors further identify the total test time, rise and fall time (ms), total / cycle time, number of rises and falls / min, pause time. Such information is recorded on hardware (3) and downloaded to a computer via an SD card. There is also the possibility that the data obtained by the step counter by telemetry can be transmitted to the computer and / or a smartphone application and the data such as number of steps up / down the steps can be viewed simultaneously on the screen of these devices. [0059] The data are analyzed using specific software designed for this purpose that can hold data from the evaluator, the user and generate a report containing, besides the data obtained by the presence sensors-hardware integration. Other inferred patient performance variables can be obtained through software calculations such as: 1) Inferred oxygen consumption: V02max (ml .min -1 . Kg -1 ) = Whor + Wvert; 2) Horizontal work performed: W hor = 0.35 x steps min -1 ; and 3) Vertical work performed: vert = a * steps min -1 * step height (m).
[0060] O sistema elétrico que faz o registro fica acomodado na região interna do degrau, apoiado na face lateral interna do equipamento. O sistema é alimentado por bateria que pode ser carregada na rede elétrica por meio de uma fonte de energia bivolt .  [0060] The electrical system that makes the registration is accommodated in the inner region of the step, supported on the inner side of the equipment. The system is battery powered which can be charged to the mains via a two volt power source.
