Abstract
Description
DISPOSIÇÃO CONSTRUTIVA APLICADA EM CARTEIRA ESCOLAR COM REGULAGEM SIMULTÂNEA E PROPORCIONAL DA ALTURA DO TAMPO E DO APOIO PARA OS PÉS. CONSTRUCTION DISPOSITION APPLIED TO A SCHOOL DESK WITH SIMULTANEOUS AND PROPORTIONAL ADJUSTMENT OF THE HEIGHT OF THE TOP AND THE FOOT REST.
[001] Refere-se a presente invenção uma carteira escolar que em um único movimento de regulagem rápida e simultânea ajusta a altura do tampo e a altura do apoio dos pés, se adaptando a qualquer estatura de usuário sem que a cadeira precise ser alterada. [001] The present invention relates to a school desk that, in a single, rapid and simultaneous adjustment movement, adjusts the height of the top and the height of the footrest, adapting to any user's height without the chair needing to be altered.
[002] Encontramos no estado da técnica os documentos MU 6802602 U e MU 7102825 U, que possuem uma carteira que ajusta a sua altura através de pares de perfilados encaixados entre si telescopicamente, com orifícios passíveis de serem atravessados por parafusos ou pinos. [002] We found in the state of the art documents MU 6802602 U and MU 7102825 U, which have a wallet that adjusts its height through pairs of profiles fitted together telescopically, with holes that can be crossed by screws or pins.
[003] Já no documento MU 8201191 -5 Y1 , as colunas da mesa são formadas por dois tubos, um no interior do outro, que permitem a aumentarem ou diminuírem a sua altura através de borboletas que fazem girar parafusos que transpassam os tubos metálicos. [003] In document MU 8201191-5 Y1, the table columns are formed by two tubes, one inside the other, which allow their height to be increased or decreased by means of butterflies that turn screws that pass through the metal tubes.
[004] Atualmente existem conjuntos de mesas e cadeiras escolares com regulagens das alturas do tampo e do assento feitos individualmente que exigem várias e demoradas operações para o ajuste da estatura do usuário. [004] There are currently sets of school tables and chairs with individually adjustable tabletop and seat heights that require several time-consuming operations to adjust to the user's height.
[005] Essa variedade de operações torna inviável o ajuste entre um turno e outro, não só pelo tempo despendido, como também pela complexidade, gerando assim margem para erros. [005] This variety of operations makes adjustments between one shift and another unfeasible, not only due to the time spent, but also due to the complexity, thus creating room for error.
[006] Tendo em vista esses problemas e no propósito de superá-los foi desenvolvido esse modelo de carteira escolar, objeto da presente patente, o qual consiste em prover uma carteira escolar com tampo e apoio para os pés interligados por um único mecanismo com engrenagens duplas com quantidade de dentes diferentes em cada parte que resguarda as proporções das distâncias entre o assento e o tampo e entre o assento e o apoio dos pés e que só pode ser acionado pressionando simultaneamente duas alavancas dispostas nas laterais opostas, este acionamento simultâneo impede a liberação involuntária do mecanismo. [006] In view of these problems and with the purpose of overcoming them, this model of school desk, which is the object of the present patent, was developed, which consists of providing a school desk with a top and footrest interconnected by a single mechanism with double gears with a different number of teeth in each part that protects the proportions of the distances between the seat and the top and between the seat and the footrest and which can only be activated by simultaneously pressing two levers arranged on opposite sides, this simultaneous activation prevents involuntary release. of the mechanism.
[007] A disposição construtiva ora descrita é compreendida por: base (1 ), hastes com cremalheira do tampo (2), hastes com cremalheira do apoio dos pés (3), alavancas com mola (4), o pino (5), as porcas (6), as engrenagens duplas (7), o apoio dos pés (8) e o tampo (9). [007] The construction arrangement described herein comprises: base (1), rods with rack of the top (2), rods with rack of the foot support (3), levers with spring (4), the pin (5), the nuts (6), the double gears (7), the foot support (8) and the top (9).
[008] A invenção poderá ser melhor compreendida através da seguinte descrição detalhada, em consonância com as Figuras em anexo onde: [008] The invention may be better understood through the following detailed description, in accordance with the attached Figures where:
[009] A FIGURA 1 representa uma vista montada, com o tampo (9) e sem tampo (9), para ser melhor entendida, com todas as partes da carteira, onde podemos ver: as duas partes da base (1 ), as duas hastes com cremalheira do tampo (2), as duas hastes com cremalheira do apoio dos pés (3), as duas alavancas com mola (4), o pino (5), o apoio dos pés (8) e o tampo (9). [009] FIGURE 1 represents an assembled view, with the top (9) and without the top (9), to be better understood, with all the parts of the wallet, where we can see: the two parts of the base (1), the two rods with rack of the top (2), the two rods with rack of the foot support (3), the two levers with spring (4), the pin (5), the foot support (8) and the top (9).
[010] A FIGURA 2 representa uma vista explodida com todas as partes da carteira, onde podemos ver: as duas partes da base (1 ), as duas hastes com cremalheira do tampo (2), as duas hastes com cremalheira do apoio dos pés (3), as duas alavancas com mola (4), o pino (5), as duas porcas (6), as duas engrenagens duplas (7), o apoio dos pés (8) e o tampo (9). [010] FIGURE 2 represents an exploded view with all the parts of the wallet, where we can see: the two parts of the base (1), the two rods with rack of the top (2), the two rods with rack of the foot support (3), the two levers with spring (4), the pin (5), the two nuts (6), the two double gears (7), the foot support (8) and the top (9).
[011 ] A FIGURA 3 mostra uma vista lateral da carteira em três regulagens, com simulação de pessoas de três tamanhos utilizando a carteira. [011 ] FIGURE 3 shows a side view of the wallet in three settings, with simulation of people of three sizes using the wallet.
[012] Com referência a estas figuras, pode-se observar a base (1 ), com as hastes com cremalheira do tampo (2), conectadas as hastes com cremalheira do apoio dos pés (3), ligadas pelas engrenagens duplas (7), fixadas pelo pino (5) e as porcas (6), travadas na posição desejada pelas alavancas com mola (4). [012] With reference to these figures, it is possible to observe the base (1), with the rack-mounted rods of the top (2), connected to the rack-mounted rods of the foot support (3), linked by the double gears (7), fixed by the pin (5) and the nuts (6), locked in the desired position by the spring levers (4).
[013] Quando as hastes com cremalheira do tampo (2) são liberadas pelas alavancas com mola (4) elas podem ser empurradas para baixo fazendo as engrenagens duplas (7) girarem e por estarem ligadas também as hastes com cremalheiras de apoio dos pés (3) fazem com que essas subam, para o movimento contrário basta pressionar o apoio dos pés (8) que é ligado as hastes com cremalheiras de apoio dos pés (3) e estas fazem as hastes com cremalheiras do tampo (2) subirem. [013] When the rack-mounted rods of the top (2) are released by the spring-loaded levers (4) they can be pushed down causing the double gears (7) to rotate and because they are also connected to the rack-mounted rods of the foot support (3) they cause them to rise, for the opposite movement simply press the foot support (8) which is connected to the rack-mounted rods of the foot support (3) and these make the rods with top racks (2) rise.
[014] A diferença na quantidade de dentes nas duas partes das engrenagens duplas (7) resulta em percursos diferentes das hastes com cremalheiras do tampo (2) e das hastes com cremalheiras do apoio dos pés (3) garantindo a proporção entre as distâncias do assento até o apoio dos pés (8) e do assento até o tampo (9). [014] The difference in the number of teeth on the two parts of the double gears (7) results in different paths for the racked rods of the top (2) and the racked rods of the footrest (3), ensuring the proportion between the distances from the seat to the footrest (8) and from the seat to the top (9).
[015] Todos esses atributos permitem classificá-lo como prático, eficiente, econômico e inovador, se enquadrando perfeitamente nos critérios que definem a patente de modelo de utilidade por sua novidade tecnológica e utilização industrial, características fundamentais para o patenteamento e suas reivindicações serão descritas a seguir. [015] All these attributes allow it to be classified as practical, efficient, economical and innovative, perfectly fitting the criteria that define the utility model patent due to its technological novelty and industrial use, fundamental characteristics for patenting and its claims will be described below.
