O âmbito dá presente invenção insere-se na área de equipamentos de apoio à construção civil direcionada para a vertente da reabilitação, . especificamente trabalhos em altura por acesso com cordas recorrendo à técnica de rappel . Acrescenta-se que ao nível da classificação internacional de patentes enquadra-se nas Â47C, A62B é E04G3. The scope of the present invention is in the area of construction support equipment directed to the rehabilitation aspect. specifically height work by rope access using the rappel technique. In addition, the level of international patent classification falls within Â47C, A62B is E04G3.
Estado da técnica State of the art
A técnica de acesso por cordas para trabalhos em alturas reduz custos operacionais e impacto do meio ambiente, pois elimina a necessidade de utilizar equipamentos tradicionais como andaimes e plataformas elevatórias para apoio aos trabalhadores , conseguindo diminuir o número de horas de operação, nomeadamente na montagem, desmontagem e transporte desses sistemas e, consequentemente, diminui os consumos energéticos dessa mesma operação. The rope access technique for working at heights reduces operating costs and environmental impact as it eliminates the need to use traditional equipment such as scaffolding and lifting platforms to support workers, reducing the number of hours of operation, including assembly, disassembly and transport of these systems and, consequently, reduces the energy consumption of this same operation.
Os profissionais ligados a área de "t abalho em altura" estão suj eitos a condições extremas de esforço físico, desconforto e, também, sujeitos a situações potencialmente perigosas com riscos para a vida humana . Neste ipo de tarefas, os equipamentos desenvolvidos devem garantir níveis de segurança elevados, bem como também níveis elevados de conforto físico, e estabilidade psicológica, durante a execução dessas tarefas. Professionals working in the field of "heights" are subject to extreme conditions of physical exertion, discomfort and also potentially hazardous situations with risks to human life. In this kind of tasks, the equipment developed shall ensure high levels of safety as well as high levels of physical comfort and psychological stability while performing these tasks.
Os equipamentos de suspensão em altura, existentes no estado da técnica, são cadeiras fixas por um único apoio (utilizados pelos operadores deste tipo de tarefas é ura apoio, onde o operador se encontra sentado) . A cadeira está fixa a uma única extremidade superior por uma "corda" ou "cabo", que podem ser elaborados em diferentes materiais, que permite evitar a queda da pessoa que estiver suspensa, era altura, na execução de uma tarefa desse tipo. State-of-the-art height suspension equipment is a single-seat fixed chair (used by operators for this type of task is a seat where the operator is seated). The chair is attached to a single upper end by a "rope" or "cable", which can be made of different materials, which allows to avoid the fall of the person who was suspended at a time when performing such a task.
Os sistemas existentes no estado da técnica provocam elevada oscilação e débeis condições ergonómicas para o trabalhador. Como ilustração sobre este problema., pode referir-se que com os equipamentos existentes o trabalhador não suporta uma jornada de trabalho contínua, tendo que descer várias vezes ao dia para descansar e realizar exercícios de alongamento muscular. State-of-the-art systems cause high oscillation and weak ergonomic conditions for the worker. As an illustration of this problem, it can be noted that with existing equipment the worker does not support a continuous workday, having to go down several times a day to rest and perform muscle stretching exercises.
A cadeira de suspensão em altura, objeto da presente invenção, garante maior segurança, maior estabilidade, maior conforto e maior autonomia do operador, quando comparada com outros que existem atualmente para essa finalidade .

A presente invenção difere do estado da técnica, uma vez que além das amarrações normais, do trabalhador, conta também com as duas da Cadeira, que se fixam ao equipamento mediante descensores e apoios para os pés, aumentado a segurança e conforto os quais são essenciais para que o trabalhador desempenhe o seu trabalho de uma forma eficaz. The present invention differs from the state of the art in that in addition to the normal lashings of the worker, it also has the two of the Chair, which attach to the equipment by means of descents and footrests, increasing safety and comfort which are essential. for the worker to perform his work effectively.
As características técnicas diferenciadoras da presente invenção contribuem para o estado da técnica, no sentido que acrescentam os seguintes efeitos técnicos: Aumento da segurança do trabalhador uma vez que para além das amarrações normais, do trabalhador, conta também com as duas da cadeira, a qual apresenta assento e encosto rígidos almofadados e revestidos com napa ; The differentiating technical characteristics of the present invention contribute to the state of the art in that they add the following technical effects: Increased worker safety since, in addition to the normal worker moorings, it also has both of the chair, which has rigid padded and covered nappa seat and back;
Estabilidade em trabalhos em altura, pois foram desenvolvidos dois apoios que se fixam ao equipamento mediante descensores , que garantem a fixação da cadeira e o movimento descendente quando apertada a cavilha que vai soltando (destravando) as cordas. 0 operador com ambas as mãos em simultâneo aperta os descensores e a cadeira vai descendo. A estabilidade aumenta porque com as duas cordas afastadas quase im torna quase improvável que a cadeira rode sobre o seu eixo (rodopie) . Torna-se bastante útil em trabalhos nas torres eólicas onde as alturas são bastante consideráveis (as torres podem atingir alturas superiores a LOOmts) e onde acontecem situações onde os trabalhadores não têm nenhuma superfície vertical próxima para apoiarem as mãos; Stability in working at heights, as two supports have been developed that are fixed to the equipment by means of sliders, which ensure the chair is fixed and the movement down when tightening the bolt that releases (unlocking) the ropes. The operator with both hands simultaneously presses the sliders and the chair descends. Stability increases because with the two ropes spaced almost apart, it makes it almost unlikely that the chair will rotate about its axis. It is very useful when working on wind towers where heights are quite considerable (towers can reach heights above LOOmts) and where situations occur where workers have no close vertical surface to support their hands;
Aumento do conforto, o que é essencial para que o trabalhador desempenhe o seu trabalho de uma forma eficaz, uma vez que um trabalhador a executar trabalhos em altura tem um desgaste brutal físico e psicológico, com este equipamento conseguimos que uma pessoa que pretenda trabalhar nesta área consiga mediante uma formação standard, trabalhar em altura, o que consequentemente resolve outro problema que existe no sector que é o da captação de mãd-de-obra. Descrição da invenção Increased comfort, which is essential for the worker to perform his work effectively, as a worker performing work at height has a brutal physical and psychological strain, with this equipment we get a person who wants to work in this This area can, by means of a standard training, work at a height, which consequently solves another problem that exists in the sector which is the capture of labor.
