The device consists of a structure consisting of two slides parallels that promote the displacement of the external apparatus along the track in each of them engraved. Said displacement is promoted by actuation of a handle that unlocks the natural position of the latch associated with the attachment mechanism of the device. In fact, the natural position of the latch locks the position of the external attachment by means of a spring, fixing its final position in one of the predefined positions in a rail that is mounted on the slide frame.

O documento EP 1514780 Al divulga uma base para acoplamento de um assento numa bicicleta. O mecanismo em causa recorre ao acionamento de uma patilha para permitir a inserção ou a remoção do assento de forma rápida. EP 1514780 A1 discloses a base for coupling a seat to a bicycle. The mechanism in question uses a tab to enable the seat to be inserted or removed quickly.
Ora, pela leitura do estado da técnica conclui-se que os sistemas desenvolvidos até agora ou recorrem ao acionamento de manipulos rotativos, ou ao ajuste de hastes de suporte, o que desde logo não facilita a tarefa do utilizador no ato da configuração da posição desejada para o assento. Para além disso, nenhuma das soluções conhecidas é pensada sob o ponto de vista da segurança do utilizador, precavendo ações inadvertidas que provoquem o deslocamento indesejado do assento, o que no caso de uma cadeira porta-bebés é um aspeto importante de garantir. From the reading of the prior art it is concluded that the systems developed so far either use rotary handles or adjusting support rods, which does not at first facilitate the user's task when setting the desired position. to the seat. Moreover, none of the known solutions is designed from the point of view of user safety, preventing inadvertent actions that cause unwanted seat displacement, which in the case of a baby seat is an important aspect to ensure.

Descrição geral General description
O presente pedido está relacionado com um sistema de fixação de assentos, em particular cadeiras de bebé ou porta-bebés, a aplicar em veículos de pelo menos duas rodas. Este sistema compreende uma estrutura de acoplamento (6), que favorece a ligação ao veículo, e uma base de pivotagem (1) projetada de forma a possibilitar o ajuste angular do assento a ele acoplado, mediante acionamento de pelo menos um manipulo de bloqueio (4) e um manipulo de ajuste (5), que funcionam de forma solidária. Deste modo evitam-se deslocações inadvertidas do assento por ação de apenas uma delas, promovendo assim a segurança do passageiro . The present application relates to a seat fastening system, in particular baby seats or baby carriers, to be fitted to vehicles of at least two wheels. This system comprises a coupling structure (6), which favors the connection to the vehicle, and a pivoting base (1) designed to allow the angular adjustment of the seat coupled to it by actuating at least one locking handle ( 4) and an adjustment handle (5), which function in solidarity. In this way inadvertent seat displacement is prevented by the action of only one of them, thus promoting passenger safety.
O sistema de fixação com ajuste angular baseia-se numa base de pivotagem (1) na qual o assento é aplicado, em particular sobre a estrutura de tubular (8) presa à superfície exterior do bloco superior da base de pivotagem (1) por intermédio dos pontos de fixação (9,10) da referida estrutura de tubular (8) e num seu ponto anterior (11) por intermédio de uma ligação mecânica, como por exemplo um parafuso . The angled adjustment fastening system is based on a pivot base (1) to which the seat is applied, in particular to the tubular frame (8) attached to the outer surface of the upper block of the pivot base (1) via of the fixing points (9,10) of said tubular structure (8) and at its anterior point (11) by means of a mechanical connection, such as a screw.
O bloco inferior da base de pivotagem (1) encontra-se encaixado na estrutura de acoplamento (6), que estabelece a conexão ao veículo. Contudo, os blocos inferior e superior da base de pivotagem (1) encontram-se ligados entre si de forma tal que permitem a existência de liberdade de deslocamento, segundo o eixo vertical, do bloco superior em relação ao bloco inferior, definindo-se nessa medida o ângulo de reclinação da base de pivotagem (1) e por extensão do assento a ela conectado. The lower block of the pivot base (1) fits into the coupling frame (6), which connects to the vehicle. However, the lower and upper blocks of the pivot base (1) are connected to each other in such a way as to allow freedom of travel along the vertical block from the upper block to the lower block by defining the reclining angle of the base (1) and by extension of the seat connected to it.
O deslocamento angular verificado concretiza-se por ação de um mecanismo rotacional, em particular uma estrutura cilíndrica (14), disposta sobre o eixo horizontal do bloco inferior da base de pivotagem (1), ao qual o bloco superior se encontra conectado através de meios de ligação mecânica, como por exemplo parafusos . O movimento giratório é controlado por pelo menos duas cabeças rotativas (12,13) montadas por encaixe mecânico em ambas extremidades laterais da referida estrutura cilíndrica (14) . The angular displacement verified is realized by action of a rotational mechanism, in particular a cylindrical structure (14), disposed on the horizontal axis of the lower block of the pivot base (1), to which the upper block is connected by means mechanical connection, such as screws. The rotary movement is controlled by at least two rotary heads (12,13) mechanically mounted on both side ends of said cylindrical structure (14).
O controlo das cabeças rotativas (12,13) é efetuado mediante a ação de pelo menos um manipulo de bloqueio (4) localizado na parte lateral do bloco superior, face de maior cumprimento, da base de pivotagem (1) . Com efeito, o manipulo de bloqueio lateral controla o funcionamento do manipulo de ajuste frontal, que por sua vez controla o movimento da base superior e por conseguinte, das cabeças rotativas . The control of the rotating heads (12,13) is performed by the action of at least one locking handle (4) located on the side of the upper block, longest face, of the pivoting base (1). Indeed, the side locking handle controls the operation of the front adjusting handle, which in turn controls the movement of the upper base and thus of the rotating heads.
O manipulo de bloqueio (4) possui duas posições, aberto e fechado, e quando se encontra nesta última posição promove o bloqueio do manipulo de ajuste (5) , localizado numa das duas faces frontais do bloco superior da base de pivotagem (1), faces de menor cumprimento. O manipulo de ajuste (5) é responsável pelo ajuste do deslocamento vertical do bloco superior em relação ao bloco inferior da base de pivotagem (1), movimento esse que é solidário com o movimento das cabeças rotativas (12,13) culminando no ajuste angular da base de pivotagem (1) . Da mesma forma, o manipulo de ajusteThe locking handle (4) has two positions, open and closed, and when in this latter position promotes locking of the adjusting handle (5), located on one of the two front faces of the upper block of the pivot base (1), less compliant faces. The adjusting handle (5) is responsible for adjusting the vertical offset of the upper block relative to the lower block of the pivot base. (1), which movement is in solidarity with the movement of the rotating heads (12,13) culminating in the angular adjustment of the pivot base (1). Similarly, the adjustment handle
(5) possui duas posições, aberto e fechado. (5) has two positions, open and closed.
Para redefinir o ajuste angular é então necessário o acionamento do manipulo de bloqueio (4) e do manipulo de ajuste (5), de forma a desbloquear a ação das cabeças rotativas (12,13) e liberar o deslocamento vertical do bloco superior da base de pivotagem (1) em relação ao seu bloco inferior, que define o ângulo de reclinação. In order to reset the angular adjustment, the locking handle (4) and the adjusting handle (5) must be actuated in order to unlock the action of the rotary heads (12,13) and release the vertical displacement of the upper base block. pivot (1) relative to its lower block, which defines the reclining angle.
Com efeito, a ajuste angular é efetuado através da abertura manipulo de bloqueio (4) que desbloqueia o manipulo de ajuste (5), promovendo a sua abertura e permitindo-se assim ajustar o deslocamento vertical do bloco superior da base de pivotagem (1) em relação ao seu bloco inferior. Esse deslocamento é efetuado ao longo da face frontal do bloco inferior, que se encontra marcada com três posições angulares de encaixe que definem ângulos de reclinação predefinidos . Após a configuração do ângulo desejado, o manipulo de ajuste (5) é fechado bloqueando o bloco superior da base de pivotagem (1) num dos encaixes angulares pré-definidos , por ação de um posicionador (15) acoplado ao manipulo de ajuste (5) . In fact, the angular adjustment is made by opening the locking handle (4) which unlocks the adjusting handle (5), promoting its opening and thus allowing the vertical displacement of the upper block of the pivoting base (1) to be adjusted. relative to its lower block. This offset is made along the front face of the lower block, which is marked with three angled snap positions that define predefined recline angles. After setting the desired angle, the adjusting handle (5) is closed by locking the upper block of the pivot base (1) in one of the predefined angle fittings by the action of a positioner (15) coupled to the adjusting handle (5). ).
De forma a coordenar a movimentação dos manipulos de bloqueio (4) e de ajuste (5), estes encontram-se conectados entre si através de um mecanismo de alavanca (16) . Assim, o manipulo de bloqueio (4), ao ser deslocado da sua posição de fecho para a posição de abertura, promove o deslocamento solidário do mecanismo de alavanca (16) para uma posição de não bloqueio ou de abertura do manipulo de ajuste (5) . Quer isto dizer que, quando o manipulo de bloqueio (4) se encontra na sua posição fechada, o mecanismo de alavanca (16) está posicionado de tal forma que bloqueia a movimentação do manipulo de ajuste (5), impedindo desta forma o ajuste angular. In order to coordinate the movement of the locking (4) and adjusting (5) handles, they are connected to each other via a lever mechanism (16). Thus, the locking handle (4), when moved from its closing position to the opening position, causes the lever mechanism (16) to move in a non-locking or opening position of the adjusting handle (5). ). Would you like That is to say, when the locking handle (4) is in its closed position, the lever mechanism (16) is positioned such that it blocks the movement of the adjusting handle (5), thereby preventing angular adjustment.
Ao deslocar verticalmente o bloco superior da base de pivotagem (1), abrindo ambos os manipulos, o posicionador do manipulo de ajuste (5) reposiciona-se dos encaixes angulares da calha de deslize (17), localizada na face frontal do bloco inferior, que permite a seleção de um encaixe angular diferente. Após seleção do ângulo pretendido, e libertando o manipulo de ajuste (5), este retoma à sua posição natural de fecho graças à ação de uma mola (19) . Quando nesta posição, o mecanismo de alavanca (16), mediante a ação da mola (18), retorna para a sua posição natural do manipulo de ajuste (5) tendo com consequência a movimentação do manipulo de bloqueio (4) para a sua posição de fecho, garantindo o trancamento do sistema de ajuste angular da base de pivotagem (1) . By vertically displacing the upper block of the pivot base (1) by opening both handles, the adjusting handle positioner (5) repositiones itself from the angled slide rail fittings (17) located on the front face of the lower block, which allows selection of a different angular fit. After selecting the desired angle and releasing the adjusting handle (5), it returns to its natural closing position thanks to the action of a spring (19). When in this position, the lever mechanism (16), by the action of the spring (18), returns to its natural position of the adjusting handle (5), consequently moving the locking handle (4) to its position. locking system, ensuring locking of the pivot base angular adjustment system (1).
Este esquema de ajuste angular aumenta a segurança dos seus utilizadores, reduzindo a probabilidade de que numa utilização normal da base de pivotagem (1) estes possam manipular o manipulo de ajuste (5) de forma inadvertida, levando à deslocação indesejada da base de pivotagem (1), como acontece nos casos em que o utilizador é uma criança que, dadas as suas dimensões, é suscetivel de poder acionar o manipulo de ajuste (5) com os seus pés ou mãos. Descrição detalhada This angular adjustment scheme increases the safety of its users by reducing the likelihood that in normal use of the pivot base (1) they will inadvertently manipulate the adjusting handle (5), leading to unwanted displacement of the pivot base ( 1), as is the case where the user is a child who, given its size, is likely to be able to operate the adjusting handle (5) with his feet or hands. Detailed Description
Fazendo referência às figuras, algumas formas de realização são agora descritas de forma mais pormenorizada, as quais não pretendem, contudo, limitar o âmbito do presente pedido . Referring to the figures, some embodiments are now described in more detail, which are not, however, intended to limit the scope of the present application.
Num modo particular de realização, a base de pivotagem (1) permite o acoplamento de uma cadeira de bebé, ou porta-bebé a bicicletas. In a particular embodiment, the pivoting base (1) allows the coupling of a baby chair or baby carrier to bicycles.
Nesse sentido sempre que o utilizador pretender alterar o ângulo de reclinação deverá acionar a patilha de bloqueioTherefore, whenever the user wants to change the recline angle, the locking lever must be activated
(4), deslocando-a para a sua posição de abertura, e posteriormente procede ao ajusta angular do bloco superior(4) by moving it to its open position, and thereafter adjusting the upper block angularly
(3), obedecendo aos encaixes representados na face frontal do bloco inferior (2), mediante acionamento da patilha de ajuste (5) e respetivo posicionador. Os ângulos de reclinação predefinidos são de 0o, 10° e 20°. Uma vez selecionado o ângulo, a patilha de ajuste (5) deixa de ser pressionada pelo utilizador, voltando à sua posição natural de fecho, que irá deslocar a alavanca (10) no sentido de fechar a patilha de bloqueio (4) e impedir o movimento das cabeças giratórias (9), trancando assim a movimentação do bloco superior (3) e fixando-o no encaixe angular desejado. (3), following the fittings shown on the front face of the lower block (2), by actuating the adjustment lever (5) and its positioner. The preset reclining angles are 0, 10 ° and 20 °. Once the angle is selected, the adjusting lever (5) is no longer depressed by the user, returning to its natural closing position, which will move the lever (10) towards closing the locking lever (4) and prevent movement of the rotary heads (9), thereby locking the movement of the upper block (3) and securing it to the desired angular fit.
O ajuste angular resulta então da ação conjunta de pelo menos duas patilhas, presentes na base de pivotagem (1), cuja ação é coordenada por um mecanismo de alavanca, que nas suas posições de fecho bloqueiam a ação do mecanismo rotacional, impedindo a movimentação das cabeças giratórias (9) e por consequência o ajuste angular da base de pivotagem (1) . Com este esquema, garante-se que o referido ajuste angular não é concretizado por ação isolada de uma das patilhas. Angular adjustment then results from the joint action of at least two tabs, present in the pivot base (1), whose action is coordinated by a lever mechanism, which in their closing positions block the action of the rotational mechanism, preventing the movement of the swivel heads (9) and consequently the angular adjustment of the pivot base (1). With this scheme, it is ensured that the above Angular adjustment is not accomplished by isolated action of one of the tabs.
