Esta solución presenta una problemática que se centra íundamentalmente en los siguientes aspectos:This solution presents a problem that focuses fundamentally on the following aspects:
- El respaldo acompaña al asiento en sus movimientos de basculación, que se producen prácticamente con misma amplitud, o con amplitud muy similar, de manera que basculaciones que pueden resultar insuficientes en un respaldo, traen consigo basculaciones excesivas.- The backrest accompanies the seat in its tilting movements, which occur practically with the same amplitude, or with very similar amplitude, so that tilts that may be insufficient in a backrest, bring excessive tilting.
- El asiento bascula a través de su borde anterior, de manera que a partir de una situación para el chasis y para el soporte de asiento, en la que el borde anterior de éste es el adecuado a la talla del usuario de la silla, dicho asiento puede descender frontalmente de una manera excesiva, o puede ascender haciendo que las piernas del usuario queden colgadas, es decir perdiendo el contacto con el suelo, lo que resulta incómodo.- The seat tilts through its front edge, so that from a situation for the chassis and for the seat support, in which the front edge of the latter is appropriate to the size of the chair user, said The seat can descend frontally in an excessive way, or it can rise causing the user's legs to hang, that is, losing contact with the ground, which is uncomfortable.
- Asiento y respaldo están distanciados una magnitud predeterminada e invariable, que en muchas ocasiones sería deseable incrementar o reducir para un mayor confort. DESCRIPCIÓN DE LA INVENCIÓN- Seat and backrest are spaced a predetermined and invariable magnitude, which in many cases would be desirable to increase or reduce for greater comfort. DESCRIPTION OF THE INVENTION
La silla de oficina que la invención propone ha sido concebida y estructurada en orden a resolver de forma plenamente satisfactoria la problemática anteriormente expuesta, en todas y cada uno de los aspectos comentados.The office chair that the invention proposes has been conceived and structured in order to solve in a fully satisfactory way the problem previously exposed, in each and every one of the aspects mentioned.
Para ello y de forma más concreta dicha silla está estructurada a partir del clásico pie estrellado, soporte del asiento y con medios de regulación en altura para éste último, con la particularidad de que dicho soporte de asiento se materializa en una base en la que participan dos piezas articuladas, una correspondiente al asiento y solidarizada inamoviblemente al pie o columna rodante, y otra articulada a la primera, proyectada hacia atrás y formando con ella un ángulo acusadamente obtuso, estando ésta segunda pieza destinada a recibir al respaldo.For this and more specifically, said chair is structured from the classic crashed foot, seat support and with height adjustment means for the latter, with the particularity that said seat support materializes on a base in which they participate two articulated pieces, one corresponding to the seat and immovably attached to the foot or rolling column, and another articulated to the first, projected backwards and forming with it a sharply obtuse angle, this second piece being destined to receive the backrest.
La primera pieza incorpora un alojamiento para una cruceta que remata el vastago de un cilindro de gas, cruceta que se fija mediante un soporte-puente convenientemente atornillado a la pieza base, estando el otro extremo del cilindro de gas destinado a fijarse a una corredera superior, de la que se hablará más adelante.The first piece incorporates a housing for a crosshead that tops the rod of a gas cylinder, a crosshead that is fixed by a bridge support conveniently screwed to the base piece, the other end of the gas cylinder being intended to be fixed to an upper slide , which will be discussed later.
Sobre la primera pieza de la base citada se establece y fija por atornillamiento un porta-mandos, que actúa a modo de tapa para dicha pieza, que es atravesado por el cilindro de gas y que incorpora una palanca lateral para actuar sobre el cilindro de gas.On the first piece of the cited base a control holder is established and fixed by screwing, which acts as a cover for said piece, which is crossed by the gas cylinder and incorporates a side lever to act on the gas cylinder .
Esta palanca actúa sobre un tetón del cilindro de gas, de manera que éste último, en lugar de funcionar a intervalos regulares, como es convencional, actúa de forma continua bloqueándose en cualquier punto de desplazamiento para su émbolo, al actuar sobre el citado tetón del mismo.This lever acts on a pin of the gas cylinder, so that the latter, instead of operating at regular intervals, as is conventional, acts continuously blocking at any point of displacement for its piston, acting on the aforementioned stud.
Sobre el conjunto descrito se monta una corredera que por su extremo posterior mediante orejetas perforadas se une articuladamente a la pieza posterior de la base, mientras que por su extremidad anterior lo hace también de forma articulada al extremo correspondiente del cilindro de gas, corredera que en su zona extrema anterior incorpora una pareja de ventanas laterales en las que juegan respectivos patines deslizantes solidarizados a la base inferior, de manera que a nivel de ésta zona extrema anterior la corredera sólo está capacitada para desplazarse horizontalmente, pero no para variar su posición en altura con respecto a la base fija.A slide is mounted on the described assembly which, at its rear end by means of perforated lugs, joins the rear part of the base articulately, while at its previous end it also joins the corresponding end of the gas cylinder, which slides in its anterior extreme zone incorporates a pair of side windows in which respective sliding skates play in solidarity with the lower base, so that at the level of this anterior extreme zone the slider is only able to move horizontally, but not to vary its position in height with respect to the fixed base.
Además ésta corredera incorpora una cremallera lateral en la que es enclavable selectivamente una especie de peine, basculante, montado sobre el asiento propiamente dicho, en orden a permitir el desplazamiento antero- posterior de dicho asiento, como se verá más adelante.In addition, this slide incorporates a side zipper in which a kind of comb, tilting comb, mounted on the seat itself, is selectively interlocked, in order to allow the anteroposterior movement of said seat, as will be seen later.
Éste desplazamiento se realiza en contra de un robusto resorte establecido en el seno de la citada corredera, montado coaxialmente sobre una especie de tornillo, resorte de tensión regulable con la colaboración de un mecanismo de transmisión tornillo-tuerca accionable desde el exterior mediante otro mando lateral y a través de un vastago que atraviesa la pared asimismo lateral de la corredera.This displacement is carried out against a sturdy spring established within the said slide, coaxially mounted on a kind of screw, tension spring adjustable with the collaboration of a screw-nut transmission mechanism operable from the outside by another lateral control and through a rod that crosses the side wall of the slide.
Finalmente sobre dicha corredera se monta el asiento propiamente dicho, por atornillamiento, asiento convenientemente acolchado y sobre cuya pared lateral, en una ventana operativamente establecida al efecto, se sitúa el citado peine basculante para enclavamiento de la cremallera.Finally, on said slide, the seat itself is mounted, by screwing, conveniently padded seat and on whose side wall, in a window operatively established for this purpose, the said tilting comb for interlocking the rack is placed.
Sólo resta señalar por último que el respaldo se fija a la pieza posterior de la base con la colaboración de una pareja de tornillos, habiéndose previsto una basculación máxima de 17 ° para dicho respaldo, que va acompañada de una basculación a su vez máxima de 4 ° para el asiento.It only remains to note finally that the backrest is fixed to the piece rear of the base with the collaboration of a pair of screws, with a maximum tilt of 17 ° for said backrest, which is accompanied by a maximum tilt of 4 ° for the seat.

A la vista de las figuras referidas puede observarse como la silla de oficina que la invención propone, a nivel de su asiento, incorpora una base estructurada mediante dos piezas, una pieza fija (1), destinada a acoplarse al pie estrellado de la silla a través de un casquillo cilindrico (2), y una pieza móvil (3) que mediante caequillos (4) se une basculantemente a la pieza fija (1). Dicha pieza fija (1) cuenta con un asiento para la cruceta (5) de un cilindro de gas (6), que queda fijado a través de dicha cruceta con la colaboración de una pieza-puente (7) anclada a la pieza base (1) mediante tornillos trilobulares (8). Éstos elementos quedan cubiertos por una especie de tapa (9), que realmente constituye un porta-mandos, que se fija a su vez mediante tornillosIn view of the aforementioned figures, it can be seen how the office chair that the invention proposes, at the level of its seat, incorporates a structured base by means of two pieces, a fixed part (1), intended to be coupled to the starry foot of the chair a through a cylindrical bushing (2), and a movable part (3) that by means of a bushing (4) joins the fixed part (1). Said fixed part (1) has a seat for the crosshead (5) of a gas cylinder (6), which is fixed through said crosshead with the collaboration of a bridge piece (7) anchored to the base part ( 1) by trilobular screws (8). These elements are covered by a kind of cover (9), which really constitutes a control holder, which is fixed in turn by screws
(10) a la pieza base (1) y que incorpora una pareja de mandos (11-11'), laterales, cuyos ejes (12) son tubulares y se enchavetan mediante un pasador (13), contando dichos mandos (11-11') con topes (14-14') para accionamiento sobre el tetón frontal (15) del cilindro de gas (6) establecido en la propia pieza base (1) o sobre el cilindro de gas del pie estrellado de sustentación, no representado en los dibujos.(10) to the base piece (1) and incorporating a pair of controls (11-11 '), lateral, whose axes (12) are tubular and keyed by a pin (13), counting said controls (11-11 ') with stops (14-14') for actuation on the front lug (15) of the gas cylinder (6) established in the base piece itself (1) or on the gas cylinder of the star bearing foot, not shown in the drawings.
La segunda pieza (3) de la base del asiento incorpora una pareja de orejetas perforadas (16) a través de las que recibe articuladamente a una corredera (17), materializada en una especie de bandeja que a su vez cuenta con orejetas (18) complementarias de las anteriores, para paso de respectivos ejes de basculación (19), materializados en tornillos asistidos por caequillos, a la vez que en su zona opuesta y también inferiormente cuenta con otras orejetas (20) que, con la colaboración de un pasador (21), permiten la fijación de dicha corredera (17) a la extremidad libre del cilindro de gas (6), como se observa especialmente en la figura 6.The second piece (3) of the seat base incorporates a pair of perforated lugs (16) through which it joins a slide (17), materialized in a kind of tray that in turn counts with lugs (18) complementary to the previous ones, for the passage of respective tilting axes (19), materialized in screws assisted by a dropper, while in its opposite area and also inferiorly it has other lugs (20) that, with the collaboration of a pin (21), allow said slide (17) to be attached to the free end of the gas cylinder (6), as can be seen in Figure 6.
La corredera (17) constituye una especie de bandeja abierta superiormente, provista en su fondo y en su extremidad anterior de dos ventanas laterales (22), en las que juegan respectivos patines (23) atornillados a protuberancias (24) de la pieza base (1), de manera que la corredera (17) es desplazable en sentido antero-posterior y fϊjable, en cualquier posición elegida para la misma y como se verá más adelante, mediante una cremallera lateral (25) y un elemento de bloqueo para la misma.The slide (17) constitutes a kind of upper open tray, provided at its bottom and at its front end with two side windows (22), in which respective skates (23) screwed to protuberances (24) of the base piece play ( 1), so that the slide (17) is movable in the antero-posterior direction and fixed, in any position chosen for it and as will be seen later, by means of a side zipper (25) and a locking element for it .
