Descripción de la invenciónDescription of the invention

La silla de oficina que la invención propone resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta en todos y cada uno de los aspectos comentados.The office chair that the invention proposes solves the problem fully satisfactorily previously exposed in each and every aspect commented.

Para ello, partiendo de la estructuración convencional de una silla de oficina, en la que participa un bastidor rodante, al que está asociada una columna telescópica dotada de un cilindro de gas, regulable a través de la correspondiente palanca, la silla de la invención centra sus características en el hecho de que la citada columna telescópica no se relaciona directamente con el asiento propiamente dicho, sino que lo hace con una pieza base, a la que se une articuladamente el respaldo, al cual se une igualmente articuladamente el asiento, el cual, por su extremidad opuesta se relaciona con el asiento base a partir de unas ranuras longitudinales practicadas en la base sobre las que es desplazable a través de las correspondientes aletas, formando dicho conjunto un triángulo articulado-deformable.To do this, based on the structuring conventional of an office chair, in which a rolling frame, to which a telescopic column is associated equipped with a gas cylinder, adjustable through the corresponding lever, the chair of the invention centers its characteristics in the fact that said telescopic column does not it relates directly to the seat itself, but which does it with a base piece, to which the backrest, to which the seat, the which, by its opposite limb is related to the base seat a from longitudinal slots made in the base on which is scrollable through the corresponding fins, said set forming a triangle articulated-deformable.

De forma más concreta, de la zona infero-anterior del asiento emergen una pareja de nervios que son desplazables longitudinalmente en las ranuras operativamente practicadas en la pieza base, de manera que para ello, entre ambas aletas se establece un vástago, igualmente desplazable en el sentido longitudinal de las ranuras, cuyo posicionamiento estará determinado por el estado de un cilindro hidráulico que por uno de sus extremos se une articuladamente a la pieza base, mientras que por el otro lo hace al comentado vástago. Paralelamente y de igual forma a ambos elementos se les asocia igualmente un muelle que trabaja a compresión, y que por tanto tenderá en todo momento a desplazar el citado vástago en sentido anterior, y consecuentemente el asiento, el cual, al estar asociado articuladamente al respaldo, hará que éste tienda igualmente a dicha posición de máxima verticalidad determinada por el recorrido extremo de las ranuras de la pieza base, quedando el grado de máxima inclinación permitido para el respaldo de la silla delimitado igualmente por el extremo opuesto de dichas ranuras.More specifically, from the area infero-anterior seat emerge a pair of nerves that are longitudinally movable in the grooves operatively practiced in the base piece, so that for this, between both fins a rod is established, also movable in the longitudinal direction of the grooves, whose positioning will be determined by the state of a cylinder hydraulic that joins one of its ends articulated to the base piece, while on the other it does the commented stem. In parallel and in the same way both elements are associated also a spring that works under compression, and therefore will tend at all times to move the aforementioned stem in the direction previous, and consequently the seat, which, when associated articulated to the backrest, it will make this shop equally to said maximum vertical position determined by the path end of the grooves of the base piece, leaving the degree of maximum inclination allowed for the back of the chair also delimited by the opposite end of said grooves.

Como resulta evidente, la regulación de la posición del respaldo no podrá llevarse a cabo sin la liberación del cilindro hidráulico, para lo cual, la pieza base, además de la clásica palanca de liberación del cilindro de la columna que permite regular la altura del asiento incorporará, preferiblemente por el lado opuesto al de dicha palanca, una segunda palanca de liberación del cilindro asociado al mecanismo de inclinación del respaldo.As is evident, the regulation of backrest position cannot be carried out without release of the hydraulic cylinder, for which the base part, in addition to the classic column cylinder release lever that allows to adjust the height of the seat will incorporate, preferably on the opposite side of said lever, a second lever of cylinder release associated with the tilt mechanism of the back.

De acuerdo con otra de las características de la invención, se ha previsto que el citado muelle que trabaja a compresión esté asociado a un mando que acciona un sinfín a través del cual se puede variar la longitud en la que queda confinado dicho muelle, es decir regular la tensión con la que se recuperará el respaldo cuando se libere el correspondiente cilindro de gas.According to another of the characteristics of the invention, it is provided that said spring working at compression is associated with a command that drives endless through of which the length in which it is confined can be varied said spring, that is to regulate the tension with which it will recover the backrest when the corresponding gas cylinder is released.

Por último, cabe destacar que la silla incorpora unos reposabrazos en los que se definen sendos pilares telescópicos, que permite regular la altura de dichos reposabrazos con respecto al asiento, siendo la pieza constitutiva del reposabrazos propiamente dicho giratoria 360º con respecto a los comentados pilares telescópicos, contando con sus correspondientes mandos de bloqueo.Finally, it should be noted that the chair incorporates some armrests in which two pillars are defined telescopic, which allows to adjust the height of said armrests with respect to the seat, being the constitutive piece of the 360º swivel armrests with respect to the commented telescopic pillars, with their corresponding lock knobs
