[0025] A presente invenção descreve um sistema que proporciona movimento retrátil e articulado a um degrau de veículo por meio de um mecanismo dotado de estruturas interconectadas de forma articulada, de modo que o travamento do movimento retrátil do degrau é realizado de forma mecânica por meio de uma trava localizada em uma das estruturas do mecanismo, o que proporciona maior estabilidade do degrau e melhor distribuição das forças de abertura e fechamento do movimento retrátil. [0025] The present invention describes a system that provides retractable and articulated movement to a vehicle step by means of a mechanism equipped with structures interconnected in an articulated way, so that the locking of the retractable movement of the step is performed mechanically by means of a lock located in one of the structures of the mechanism, which provides greater stability of the step and better distribution of the opening and closing forces of the retractable movement.
[0026] Para fins da presente invenção, o “veículo” pode ser considerado um veículo de transporte coletivo como, por exemplo, ônibus, micro-ônibus, van, etc., ou qualquer veículo que possua degraus para acessar a parte interna do veículo. [0026] For the purposes of the present invention, the "vehicle" can be considered a public transport vehicle such as, for example, bus, minibus, van, etc., or any vehicle that has steps to access the interior of the vehicle .
[0027] Em um primeiro objeto, a presente invenção apresenta um sistema articulado para degrau retrátil de veículo compreendendo ao menos mecanismo de travamento, sendo o mecanismo de travamento dotado de ao menos quatro regiões (3, 4, 5, 6) interconectadas de forma articulada e ao menos um cilindro pistão (1) conectado em ao menos uma das quatro regiões (3, 4, 5, 6), em que as ditas quatro regiões (3, 4, 5, 6) interconectadas provem movimento retrátil e travamento mecânico a um degrau (7) em relação a uma estrutura de suporte (2) do veículo. [0027] In a first object, the present invention presents an articulated system for a vehicle retractable step comprising at least a locking mechanism, the locking mechanism having at least four regions (3, 4, 5, 6) interconnected in a manner articulated and at least one piston cylinder (1) connected in at least one of the four regions (3, 4, 5, 6), in which said four interconnected regions (3, 4, 5, 6) provide retractable movement and mechanical locking to a step (7) in relation to a support structure (2) of the vehicle.
[0028] Em uma concretização, a estrutura de suporte (2) do veículo compreende uma estrutura de degrau fixa na carroceria do veículo e disposta nas regiões de entrada e saída de usuários do veículo, em que a estrutura é posicionada disposto acima do degrau retrátil (7). [0028] In one embodiment, the support structure (2) of the vehicle comprises a step structure fixed to the vehicle body and arranged in the entry and exit regions of vehicle users, in which the structure is positioned above the retractable step (7).
[0029] Em uma concretização, o mecanismo de travamento é formado por uma primeira região (3), uma segunda região (4), uma terceira região (5) e uma quarta região (6) interconectadas uma à outra de forma articulada, e conectadas ao degrau (7) e à estrutura de suporte (2), de modo que o arranjo de conexão das quatro regiões (3, 4, 5, 6) proporciona movimento retrátil e articulado ao degrau (7), bem como o travamento mecânico do movimento retrátil. [0029] In one embodiment, the locking mechanism is formed by a first region (3), a second region (4), a third region (5) and a fourth region (6) interconnected to each other in a hinged manner, and connected to the step (7) and the support structure (2), so that the connection arrangement of the four regions (3, 4, 5, 6) provides retractable and articulated movement to the step (7), as well as mechanical locking of the retractable movement.
[0030] Em uma concretização, a primeira região (3) das quatro regiões (3, 4, 5, 6) interconectadas do mecanismo de travamento compreende uma extremidade (3.1) conectada de forma articulada ao degrau (7) e uma extremidade (3.2) conectada de forma articulada em uma estrutura de suporte (2). Em uma concretização, a estrutura da primeira região (3) compreende geometria reta conectando o degrau (7) à estrutura de suporte (2). [0030] In one embodiment, the first region (3) of the four interconnected regions (3, 4, 5, 6) of the locking mechanism comprises an end (3.1) pivotally connected to the step (7) and an end (3.2) ) hingedly connected to a support structure (two). In one embodiment, the structure of the first region (3) comprises straight geometry connecting the step (7) to the support structure (2).
[0031] Em uma concretização, uma segunda região (4) das quatro regiões (3, 4, 5, 6) interconectadas do mecanismo de travamento compreende: uma aba dotada de uma trava mecânica (4.3); uma extremidade (4.1) conectada em um ponto entre a extremidade (3.1) e a extremidade (3.2) da primeira região (3); e uma extremidade (4.2) conectada em uma terceira região (5). Em uma concretização, a estrutura da segunda região (4) compreende geometria curvada conectando a primeira região (3) à terceira região (5). [0031] In one embodiment, a second region (4) of the four interconnected regions (3, 4, 5, 6) of the locking mechanism comprises: a flap provided with a mechanical lock (4.3); an end (4.1) connected at a point between the end (3.1) and the end (3.2) of the first region (3); and one end (4.2) connected in a third region (5). In one embodiment, the structure of the second region (4) comprises curved geometry connecting the first region (3) to the third region (5).
[0032] Em uma concretização, a trava mecânica (4.3) da aba da segunda região (4) compreende um dispositivo limitador fixado à aba por meio de um parafuso possuindo a função de limitar e travar o movimento retrátil de abertura do degrau (7) em uma posição predeterminada. Em uma concretização, o travamento do movimento de abertura do degrau (7) é realizado quando a trava mecânica (4.3) está em uma posição articulada junto à estrutura de suporte (2). [0033] Em uma concretização, uma terceira região (5) das quatro regiões (3, 4, 5, 6) interconectadas do mecanismo de travamento compreende: uma extremidade (5.1) conectada à extremidade (4.2) da segunda região (4); uma extremidade (5.2) conectada de forma articulada em uma estrutura de suporte (2) e em uma extremidade (6.1) de uma quarta região (6); um ponto de conexão (5.3) articulada com o cilindro pistão (1) entre a extremidade (5.1) e a extremidade (5.2); e uma aba de travamento (5.2) do movimento da trava mecânica (4.3). [0032] In one embodiment, the mechanical lock (4.3) of the flap of the second region (4) comprises a limiting device attached to the flap by means of a screw having the function of limiting and locking the retractable opening movement of the step (7) in a predetermined position. In one embodiment, locking the opening movement of the step (7) is performed when the mechanical lock (4.3) is in an articulated position next to the support structure (2). [0033] In one embodiment, a third region (5) of the four interconnected regions (3, 4, 5, 6) of the locking mechanism comprises: an end (5.1) connected to the end (4.2) of the second region (4); one end (5.2) pivotally connected to a support structure (2) and one end (6.1) to a fourth region (6); a connection point (5.3) articulated with the piston cylinder (1) between the end (5.1) and the end (5.2); and a locking flap (5.2) for the movement of the mechanical lock (4.3).
[0034] Em uma concretização, a aba de travamento (5.2) da terceira região (5) compreende uma estrutura limitadora do movimento de abertura articulada da trava mecânica (4.3) da segunda região (4), visto que a aba de travamento (5.2), ao entrar em contato com a trava mecânica (4.3) em uma posição predeterminada do movimento de abertura retrátil do degrau (7), limita o movimento articulado da segunda região (4) e, consequentemente, limita o movimento de todas as quatro regiões (3, 4, 5, 6) do mecanismo de travamento. [0035] Em uma concretização, a estrutura da terceira região (5) compreende geometria curvada do tipo boomerang. Em uma concretização, a extremidade (5.1) da terceira região (5) é conectada à extremidade (4.2) da segunda região (4) e a extremidade (5.2) da terceira região (5) é conectada de forma articulada à estrutura de suporte (2) e à extremidade (6.1) de uma quarta região (6). [0034] In one embodiment, the locking tab (5.2) of the third region (5) comprises a structure that limits the movement of the articulated opening of the mechanical lock (4.3) of the second region (4), since the locking tab (5.2 ), when coming into contact with the mechanical lock (4.3) in a predetermined position of the retractable opening movement of the step (7), limits the joint movement of the second region (4) and, consequently, limits the movement of all four regions (3, 4, 5, 6) of the locking mechanism. [0035] In one embodiment, the structure of the third region (5) comprises curved boomerang-type geometry. In one embodiment, the end (5.1) of the third region (5) is connected to the end (4.2) of the second region (4) and the end (5.2) of the third region (5) is hingedly connected to the support structure ( 2) and to the end (6.1) of a fourth region (6).
[0036] Em uma concretização, a extremidade inferior do cilindro pistão (1 ) é fixada em um ponto de conexão (5.3) articulada entre a extremidade (5.1) e a extremidade (5.2) da terceira região (5). [0036] In one embodiment, the lower end of the piston cylinder (1) is attached to a connection point (5.3) articulated between the end (5.1) and the end (5.2) of the third region (5).
[0037] Em uma concretização, a extremidade superior do cilindro pistão[0037] In one embodiment, the upper end of the piston cylinder
(1) é conectada de forma articulada em uma aba superior (2.1) da estrutura de suporte (2). (1) is hingedly connected to an upper flap (2.1) of the support structure (2).
[0038] Em uma concretização, uma quarta região (6) das quatro regiões (3, 4, 5, 6) interconectadas do mecanismo de travamento compreende uma extremidade (6.1) conectada de forma articulada em uma estrutura de suporte[0038] In one embodiment, a fourth region (6) of the four interconnected regions (3, 4, 5, 6) of the locking mechanism comprises an end (6.1) hingedly connected to a support structure
(2) e na extremidade (5.1) da terceira região (5), e uma extremidade (6.2) conectada de forma articulada ao degrau (7). Desta forma, a quarta região (6) conecta articuladamente o degrau (7) à estrutura de suporte (2). (2) and at the end (5.1) of the third region (5), and one end (6.2) hingedly connected to the step (7). In this way, the fourth region (6) pivotally connects the step (7) to the support structure (2).
[0039] Em uma concretização, a estrutura da quarta região (6) compreende geometria curvada e dotada de ao menos uma saliência (6.3) que auxilia no travamento do movimento de abertura do degrau (7). [0039] In one embodiment, the structure of the fourth region (6) comprises curved geometry and is provided with at least one projection (6.3) that assists in locking the opening movement of the step (7).
[0040] Desta forma, o movimento retrátil do degrau (7) é limitado em uma posição aberta de uso por meio do travamento da trava mecânica (4.3) da aba da segunda região (4) junto à aba de travamento (5.2) da terceira região (5) em um ponto localizado junto à estrutura de suporte (2), isto é, quando a aba de travamento (5.2) entra em contato com a trava mecânica (4.3) durante o movimento de abertura retrátil do degrau (7). [0040] In this way, the retractable movement of the step (7) is limited in an open position of use by locking the mechanical lock (4.3) of the flap of the second region (4) next to the locking flap (5.2) of the third region (5) at a point located next to the support structure (2), that is, when the locking flap (5.2) comes into contact with the mechanical lock (4.3) during the retractable opening movement of the step (7).
[0041] A referida limitação de movimento de forma mecânica realizada pelo sistema da presente invenção proporciona maior estabilidade ao degrau (7) e melhor distribuição das forças de abertura e fechamento do movimento retrátil do degrau (7), visto que a estabilidade do degrau (7) não depende do trabalho realizado pelo cilindro pistão (1), mas sim pelo travamento mecânico da trava mecânica (4.3) junto à aba de travamento (5.2). [0041] Said mechanical movement limitation performed by the system of the present invention provides greater stability to the step (7) and better distribution of the opening and closing forces of the retractable movement of the step (7), since the stability of the step (7) does not depend on the work done by the piston cylinder (1), but on the mechanical locking of the mechanical lock (4.3) next to the locking tab (5.2).
[0042] Em um segundo objeto, a presente invenção apresenta um processo de montagem de sistema articulado para degrau retrátil de veículo compreendendo as etapas de: a. associação articulada de ao menos um cilindro pistão (1 ) em ao menos uma aba superior (2.1) de uma estrutura de suporte (2) do veículo; b. associação articulada do cilindro pistão (1) em ao menos uma de quatro regiões (3, 4, 5, 6) de um mecanismo de travamento; e c. associação retrátil e articulada da estrutura de suporte (2) em ao menos um degrau (7) por meio da associação articulada de ao menos uma das quatro regiões (3, 4, 5, 6) do mecanismo de travamento ao degrau (7) e à estrutura de suporte (2). [0042] In a second object, the present invention presents an assembly process for an articulated system for a vehicle retractable step comprising the steps of: a. articulated association of at least one piston cylinder (1) in at least one upper flap (2.1) of a support structure (2) of the vehicle; B. articulated association of the piston cylinder (1) in at least one of four regions (3, 4, 5, 6) of a locking mechanism; and c. retractable and articulated association of the support structure (2) in at least one step (7) through the articulated association of at least one of the four regions (3, 4, 5, 6) of the locking mechanism to the step (7) and to the support structure (2).
[0043] Em uma concretização, a associação retrátil e articulada da estrutura de suporte (2) ao degrau (7) é proporcionada por um mecanismo de travamento dotado de regiões (3, 4, 5, 6) interconectadas de forma articulada com o degrau (7), com a estrutura de suporte (2) e com ao menos um cilindro pistão (1). [0043] In one embodiment, the retractable and articulated association of the support structure (2) to the step (7) is provided by a locking mechanism provided with regions (3, 4, 5, 6) articulately interconnected with the step (7), with the support structure (2) and with at least one piston cylinder (1).
[0044] Em uma concretização, o mecanismo de travamento é formado por uma primeira região (3), uma segunda região (4), uma terceira região (5) e uma quarta região (6) interconectadas uma à outra de forma articulada, e conectadas ao degrau (7) e à estrutura de suporte (2), de modo que o arranjo de conexão das quatro regiões (3, 4, 5, 6) proporciona movimento retrátil e articulado ao degrau (7), bem como o travamento mecânico do movimento retrátil. [0044] In one embodiment, the locking mechanism is formed by a first region (3), a second region (4), a third region (5) and a fourth region (6) interconnected to each other in a hinged manner, and connected to the step (7) and the support structure (2), so that the connection arrangement of the four regions (3, 4, 5, 6) provides retractable and articulated movement to the step (7), as well as mechanical locking of the retractable movement.
[0045] Em uma concretização, a dita associação do mecanismo de travamento ao degrau (7) e à estrutura de suporte (2) compreende as seguintes etapas: a. associação articulada de uma extremidade (3.1 ) da primeira região (3) do mecanismo de travamento ao degrau (7) e associação articulada de uma extremidade (3.2) da primeira região (3) à estrutura de suporte (2); b. associação articulada de uma extremidade (4.1 ) da segunda região (4) do mecanismo de travamento em um ponto entre a extremidade (3.1) e a extremidade (3.2) da primeira região (3), e associação articulada de uma extremidade (4.2) à uma terceira região (5) do mecanismo de travamento; c. associação articulada de uma extremidade (5.1) da terceira região (5) do mecanismo de travamento à extremidade (4.2) da segunda região (4), e associação articulada de uma extremidade (5.2) à estrutura de suporte (2) e em uma extremidade (6.1 ) de uma quarta região (6) do mecanismo de travamento; d. associação articulada do cilindro pistão (1) em um ponto de conexão (5.3) entre a extremidade (5.1) e a extremidade (5.2) da terceira região (5) do mecanismo de travamento; e e. associação articulada da extremidade (6.1 ) da quarta região (6) do mecanismo de travamento à uma estrutura de suporte (2) e à extremidade (5.2) da terceira região (5) e associação articulada de uma extremidade (6.2) da quarta região (6) ao degrau (7). [0045] In one embodiment, said association of the locking mechanism to the step (7) and the support structure (2) comprises the following steps: The. articulated association of one end (3.1) of the first region (3) of the locking mechanism to the step (7) and articulated association of one end (3.2) of the first region (3) with the support structure (2); B. pivotal association of one end (4.1) of the second region (4) of the locking mechanism at a point between the end (3.1) and the end (3.2) of the first region (3), and pivotal association of one end (4.2) to a third region (5) of the locking mechanism; ç. articulated association of one end (5.1) of the third region (5) of the locking mechanism to the end (4.2) of the second region (4), and articulated association of one end (5.2) to the support structure (2) and at one end (6.1) of a fourth region (6) of the locking mechanism; d. articulated association of the piston cylinder (1) at a connection point (5.3) between the end (5.1) and the end (5.2) of the third region (5) of the locking mechanism; and is. articulated association of the end (6.1) of the fourth region (6) of the locking mechanism to a support structure (2) and the end (5.2) of the third region (5) and articulated association of one end (6.2) of the fourth region ( 6) to the step (7).
[0046] Em uma concretização, a terceira região (5) compreende uma aba de travamento (5.2) dotada de uma estrutura limitadora do movimento de abertura articulada de uma trava mecânica (4.3) da segunda região (4), visto que a aba de travamento (5.2), ao entrar em contato com a trava mecânica (4.3) em uma posição predeterminada do movimento de abertura retrátil do degrau, limita o movimento articulado da segunda região (4) e, consequentemente, limita o movimento de todas as quatro regiões (3, 4, 5, 6) do mecanismo de travamento. [0047] Desta forma, a referida montagem do mecanismo de travamento permite que o degrau (7) se movimente de forma articulada e retrátil e seja limitado e travado de forma mecânica quando a aba de travamento (5.2) entra em contato com a trava mecânica (4.3) durante o movimento de abertura retrátil do degrau (7). [0046] In one embodiment, the third region (5) comprises a locking flap (5.2) provided with a structure that limits the movement of the hinged opening of a mechanical lock (4.3) of the second region (4), since the locking flap locking (5.2), when in contact with the mechanical lock (4.3) in a predetermined position of the retractable opening movement of the step, limits the joint movement of the second region (4) and, consequently, limits the movement of all four regions (3, 4, 5, 6) of the locking mechanism. [0047] In this way, said assembly of the locking mechanism allows the step (7) to move in an articulated and retractable manner and be limited and locked mechanically when the locking flap (5.2) comes into contact with the mechanical lock (4.3) during the retractable opening movement of the step (7).
[0048] A referida limitação de movimento de forma mecânica proporcionada pela associação articulada das quatro regiões (3, 4, 5, 6) do mecanismo de travamento proporciona maior estabilidade ao degrau (7) e melhor distribuição das forças de abertura e fechamento do movimento retrátil do degrau (7), visto que a estabilidade do degrau (7) não depende do trabalho realizado pelo cilindro pistão (1), mas sim pelo travamento mecânico da trava mecânica (4.3) junto à aba de travamento (5.2). [0048] Said mechanical movement limitation provided by the articulated association of the four regions (3, 4, 5, 6) of the locking mechanism provides greater stability to the step (7) and better distribution of the opening and closing forces of the movement retractable step (7), since the stability of the step (7) does not depend on the work done by the piston cylinder (1), but on the mechanical locking of the mechanical lock (4.3) next to the locking tab (5.2).
[0049] Em um terceiro objeto, a presente invenção apresenta um veículo de transporte coletivo compreendendo ao menos uma carroceria, em que a carroceria compreende regiões de entrada e saída de usuários dotadas de uma estrutura de suporte (2) de degrau (7) retrátil, o veículo compreendendo um sistema articulado para degrau retrátil compreendendo ao menos mecanismo de travamento provido com ao menos quatro regiões (3, 4, 5, 6) interconectadas de forma articulada e ao menos um cilindro pistão (1) conectado em ao menos uma das quatro regiões (3, 4, 5, 6), em que as ditas quatro regiões (3, 4, 5, 6) interconectadas provem movimento retrátil a um degrau (7) em relação a uma estrutura de suporte (2) do veículo. [0049] In a third object, the present invention presents a public transport vehicle comprising at least one body, in which the body comprises user entry and exit regions equipped with a support structure (2) with retractable step (7) , the vehicle comprising an articulated system for a retractable step comprising at least a locking mechanism provided with at least four regions (3, 4, 5, 6) interconnected in an articulated way and at least one piston cylinder (1) connected in at least one of the four regions (3, 4, 5, 6), wherein said four interconnected regions (3, 4, 5, 6) provide retractable movement to a step (7) relative to a support structure (2) of the vehicle.
[0050] Em uma concretização, o mecanismo de travamento é formado por uma primeira região (3), uma segunda região (4), uma terceira região (5) e uma quarta região (6) interconectadas uma à outra de forma articulada, e conectadas ao degrau (7) e à estrutura de suporte (2), de modo que o arranjo de conexão das quatro regiões (3, 4, 5, 6) proporciona movimento retrátil e articulado ao degrau (7), bem como o travamento mecânico do movimento retrátil. [0050] In one embodiment, the locking mechanism is formed by a first region (3), a second region (4), a third region (5) and a fourth region (6) interconnected to each other in a hinged manner, and connected to the step (7) and the support structure (2), so that the connection arrangement of the four regions (3, 4, 5, 6) provides retractable and articulated movement to the step (7), as well as mechanical locking of the retractable movement.
[0051] Em uma concretização, a terceira região (5) compreende uma aba de travamento (5.2) dotada de uma estrutura limitadora do movimento de abertura articulada de uma trava mecânica (4.3) da segunda região (4), visto que a aba de travamento (5.2), ao entrar em contato com a trava mecânica (4.3) em uma posição predeterminada do movimento de abertura retrátil do degrau, limita o movimento articulado da segunda região (4) e, consequentemente, limita o movimento de todas as quatro regiões (3, 4, 5, 6) do mecanismo de travamento. [0052] Desta forma, o mecanismo de travamento permite que o degrau (7) se movimente de forma articulada e retrátil e seja limitado e travado de forma mecânica quando a aba de travamento (5.2) entra em contato com a trava mecânica (4.3) durante o movimento de abertura retrátil do degrau (7). [0051] In one embodiment, the third region (5) comprises a locking flap (5.2) provided with a structure that limits the movement of the hinged opening of a mechanical lock (4.3) of the second region (4), since the locking flap lock (5.2), when in contact with the mechanical lock (4.3) in a predetermined position of the retractable opening movement of the step, limits the articulated movement of the second region (4) and, consequently, limits the movement of all four regions (3, 4, 5, 6) of the locking mechanism. [0052] In this way, the locking mechanism allows the step (7) to move in an articulated and retractable way and to be mechanically limited and locked when the locking tab (5.2) comes into contact with the mechanical lock (4.3) during the retractable opening movement of the step (7).
[0053] Assim, o veículo possuindo o dito sistema articulado para degrau retrátil da presente invenção permite que o degrau (7) tenha seu movimento de abertura limitado de forma mecânica através da associação articulada das quatro regiões (3, 4, 5, 6) do mecanismo de travamento, o que proporciona maior estabilidade ao degrau (7) e melhor distribuição das forças de abertura e fechamento do movimento retrátil do degrau (7), visto que a estabilidade do degrau (7) não depende do trabalho realizado pelo cilindro pistão (1), mas sim pelo travamento mecânico da trava mecânica (4.3) junto à aba de travamento (5.2). [0053] Thus, the vehicle having said articulated system for the retractable step of the present invention allows the step (7) to have its opening movement limited mechanically through the articulated association of the four regions (3, 4, 5, 6) of the locking mechanism, which provides greater stability to the step (7) and better distribution of the opening and closing forces of the retractable movement of the step (7), since the stability of the step (7) does not depend on the work performed by the piston cylinder (1), but by the mechanical locking of the mechanical lock (4.3) next to the locking tab (5.2).
Exemplo 1 - Degrau retrátil para ônibus Example 1 - Retractable step for buses
[0054] Os exemplos aqui mostrados têm o intuito somente de exemplificar uma das inúmeras maneiras de se realizar a invenção, contudo sem limitar, o escopo da mesma. [0054] The examples shown here are intended only to exemplify one of the many ways to carry out the invention, but without limiting its scope.
[0055] Neste exemplo, foi desenvolvido um sistema articulado para degrau retrátil de ônibus possuindo um mecanismo de travamento mecânico. O mecanismo de travamento possui 4 regiões (3, 4, 5, 6) interconectadas uma à outra de forma articulada que proporcionam movimento retrátil articulado ao degrau (7) em relação a um degrau fixo (2) da estrutura do ônibus, bem como o travamento mecânico do movimento retrátil. [0055] In this example, an articulated system was developed for a retractable bus step with a mechanical locking mechanism. The locking mechanism has 4 regions (3, 4, 5, 6) interconnected to each other in an articulated way that provide articulated retractable movement to the step (7) in relation to a fixed step (2) of the bus structure, as well as the mechanical locking of the retractable movement.
[0056] O mecanismo de travamento é associado nas duas partes laterais do degrau (7). A figura 3 mostra uma vista em perspectiva ilustrando em detalhe o mecanismo de travamento e as interconexões entre cada uma das quatro regiões (3, 4, 5, 6). [0056] The locking mechanism is associated with the two sides of the step (7). Figure 3 shows a perspective view illustrating in detail the locking mechanism and the interconnections between each of the four regions (3, 4, 5, 6).
[0057] A figura 1 mostra uma vista anterior do sistema articulado para degrau retrátil desenvolvido, sendo que o degrau (7) se encontra em uma posição aberta/expandida para uso pelos usuários, e a figura 2 mostra uma vista anterior do sistema articulado desenvolvido, sendo que o degrau (7) se encontra em uma posição fechada/retraída. As figuras 1 e 2 ilustram todas as interconexões entre as regiões (3, 4, 5, 6) do mecanismo de travamento, as quais são descritas e detalhadas a seguir. [0057] Figure 1 shows a front view of the joint system for the retractable step developed, with the step (7) being in an open/expanded position for use by users, and figure 2 shows a front view of the joint system developed , and the step (7) is in a closed/retracted position. Figures 1 and 2 illustrate all the interconnections between regions (3, 4, 5, 6) of the locking mechanism, which are described and detailed below.
[0058] A primeira região (3) das quatro regiões (3, 4, 5, 6) possui geometria reta e possui uma extremidade (3.1) conectada ao degrau (7) e uma extremidade (3.2) conectada ao degrau fixo (2). [0058] The first region (3) of the four regions (3, 4, 5, 6) has straight geometry and has an end (3.1) connected to the step (7) and an end (3.2) connected to the fixed step (2) .
[0059] A segunda região (4) das quatro regiões (3, 4, 5, 6) possui geometria curvada e possui uma aba dotada de uma trava mecânica (4.3). Ainda, possui uma extremidade (4.1) conectada em um ponto entre a extremidade (3.1) e a extremidade (3.2) da primeira região (3), e uma extremidade (4.2) conectada em uma terceira região (5). [0059] The second region (4) of the four regions (3, 4, 5, 6) has curved geometry and has a flap equipped with a mechanical lock (4.3). Still, it has an end (4.1) connected at a point between the end (3.1) and the end (3.2) of the first region (3), and an end (4.2) connected to a third region (5).
[0060] A terceira região (5) das quatro regiões (3, 4, 5, 6) possui geometria do tipo boomerang, onde uma extremidade (5.1 ) é conectada à extremidade (4.2) da segunda região (4), uma extremidade (5.2) é conectada ao degrau fixo (2) e em uma extremidade (6.1) da quarta região (6) [0060] The third region (5) of the four regions (3, 4, 5, 6) has boomerang-type geometry, where one end (5.1 ) is connected to the end (4.2) of the second region (4), one end ( 5.2) is connected to the fixed step (2) and at one end (6.1) of the fourth region (6)
[0061] Ainda, um cilindro pneumático (1 ) é conectado à terceira região (5) em um ponto de conexão (5.3) localizado entre a extremidade (5.1) e a extremidade (5.2) e em uma aba superior (2.1) da estrutura de suporte (2). [0062] Além do mais, a terceira região (5) possui uma aba de travamento (5.2) do movimento da trava mecânica (4.3) da segunda região (4). [0061] Also, a pneumatic cylinder (1) is connected to the third region (5) at a connection point (5.3) located between the end (5.1) and the end (5.2) and an upper flap (2.1) of the structure support (2). [0062] Furthermore, the third region (5) has a locking flap (5.2) of the movement of the mechanical lock (4.3) of the second region (4).
[0063] A aba de travamento (5.2) da terceira região (5) limita o movimento de abertura articulada da trava mecânica (4.3) da segunda região (4), visto que a aba de travamento (5.2), ao entrar em contato com a trava mecânica (4.3) em uma posição predeterminada do movimento de abertura retrátil do degrau (7), limita o movimento articulado da segunda região (4) e, consequentemente, limita o movimento de todas as quatro regiões (3, 4, 5, 6) do mecanismo de travamento, visto que todas as quatro regiões (3, 4, 5, 6) são interconectadas. [0064] A quarta região (6) das quatro regiões (3, 4, 5, 6) interconectadas possui geometria curvada dotada de uma extremidade (6.1) conectada ao degrau fixo (2) e à extremidade (5.1) da terceira região (5), e uma extremidade (6.2) conectada ao degrau (7). Ainda, a quarta região (6) é dotada de duas saliências (6.3) que auxiliam no travamento do movimento de abertura do degrau (7). [0063] The locking tab (5.2) of the third region (5) limits the hinged opening movement of the mechanical lock (4.3) of the second region (4), since the locking tab (5.2), when in contact with the mechanical lock (4.3) in a predetermined position of the retractable opening movement of the step (7), limits the articulated movement of the second region (4) and, consequently, limits the movement of all four regions (3, 4, 5, 6) of the locking mechanism, as all four regions (3, 4, 5, 6) are interconnected. [0064] The fourth region (6) of the four interconnected regions (3, 4, 5, 6) has curved geometry with an end (6.1) connected to the fixed step (2) and to the end (5.1) of the third region (5 ), and one end (6.2) connected to the step (7). Still, the fourth region (6) is equipped with two protrusions (6.3) that help in locking the opening movement of the step (7).
[0065] Desta forma, o movimento retrátil do degrau (7) é limitado em uma posição aberta de uso por meio do travamento da trava mecânica (4.3) da aba da segunda região (4) junto à aba de travamento (5.2) da terceira região (5) em um ponto localizado junto à estrutura de suporte (2), isto é, quando a aba de travamento (5.2) entra em contato com a trava mecânica (4.3) durante o movimento de abertura retrátil do degrau (7). A figura 5 ilustra o mecanismo de travamento expandindo o degrau (7) em uma posição aberta para utilização pelo usuário e a figura ilustra o mecanismo de travamento retraindo o degrau (7) em uma posição fechada. [0065] In this way, the retractable movement of the step (7) is limited in an open position of use by locking the mechanical lock (4.3) of the flap of the second region (4) next to the locking flap (5.2) of the third region (5) at a point located next to the support structure (2), that is, when the locking flap (5.2) comes into contact with the mechanical lock (4.3) during the retractable opening movement of the step (7). Figure 5 illustrates the locking mechanism expanding the step (7) in an open position for use by the user and the figure illustrates the locking mechanism retracting the step (7) in a closed position.
[0066] Assim, o travamento mecânico proporcionado pelo sistema desenvolvido proporciona maior estabilidade ao degrau (7) e melhor distribuição das forças de abertura e fechamento do movimento retrátil do degrau (7), visto que a estabilidade do degrau (7) não depende do trabalho realizado pelo cilindro pistão (1), mas sim pelo travamento mecânico da trava mecânica (4.3) junto à aba de travamento (5.2). [0066] Thus, the mechanical locking provided by the developed system provides greater stability to the step (7) and better distribution of the opening and closing forces of the retractable movement of the step (7), since the stability of the step (7) does not depend on the work performed by the piston cylinder (1), but by the mechanical locking of the mechanical lock (4.3) next to the locking tab (5.2).
[0067] Ademais, as forças de abertura e fechamento do degrau (7) são otimizadas, tendo o trabalho realizado através de dois cilindros pneumáticos cuja força total não é capaz de machucar alguma pessoa ou danificar o sistema caso exista alguma obstrução do movimento de abertura/fechamento do degrau (7). [0068] Os versados na arte valorizarão os conhecimentos aqui apresentados e poderão reproduzir a invenção nas modalidades apresentadas e em outras variantes e alternativas, abrangidas pelo escopo das reivindicações a seguir. [0067] In addition, the opening and closing forces of the step (7) are optimized, with the work performed through two pneumatic cylinders whose total force is not capable of hurting anyone or damaging the system if there is any obstruction of the opening movement /closing the step (7). [0068] Those versed in the art will value the knowledge presented here and will be able to reproduce the invention in the modalities presented and in other variants and alternatives, covered by the scope of the claims Next.
