MODO DE REALIZACION PREFERENTE PREFERRED EMBODIMENT
15 A la vista de las figuras indicadas, se puede observar que la silla de oficina propuesta por la invenci6n incorpora, a nivel de su asiento, una base estructurada en dos partes: una parte fija (1) para acoplar a la pata en forma de estrella de la silla, a traves de un casquillo cilindrico (2), y una parte m6vil (3) que se une, de manera giratoria, a la parte fija (1) mediante cojinetes (4). Dicha parte fija (1) dispone de un asiento en la parte transversal (5) 15 In view of the indicated figures, it can be seen that the office chair proposed by the invention incorporates, at the level of its seat, a base structured in two parts: a fixed part (1) for coupling to the leg in the form of star of the chair, through a cylindrical bushing (2), and a mobile part (3) that is rotatably joined to the fixed part (1) by means of bearings (4). Said fixed part (1) has a seat in the transverse part (5)
20 de un cilindro neumatico (6), que se fija a traves de dicha pieza transversal con la ayuda de una pieza puente (7) anclada en la parte de la base (1) mediante tornillos trilobulares (8). Dichos elementos quedan cubiertos por una especie de tapa (9), formando un mando de regulaci6n que, a su vez, se fija mediante tornillos (10) a la parte de la base (1) y se incorporan un par de mandos laterales (11-11'), los ejes (12) que son tubulares y estan 20 of a pneumatic cylinder (6), which is fixed through said transverse piece with the help of a bridge piece (7) anchored in the base part (1) by means of three-lobed screws (8). Said elements are covered by a kind of cover (9), forming a control knob which, in turn, is fixed by screws (10) to the base part (1) and a pair of side controls (11) are incorporated. -11 '), the shafts (12) that are tubular and are
25 calzados con un pivote (13);dichos mandos (11, 11') disponen de unos topes (14-14') para accionar la asidera frontal (15) del cilindro neumatico (6) dispuesto en la parte de la base (1) en si misma o sobre el cilindro neumatico del soporte de pata en forma de estrella, que no se muestra en los dibujos. 25 shoes with a pivot (13); said controls (11, 11 ') have stops (14-14') for operating the front handle (15) of the pneumatic cylinder (6) arranged in the base part (1) ) itself or on the pneumatic cylinder of the star-shaped leg support, which is not shown in the drawings.
La segunda parte (3) de la base del asiento incorpora un par de lenguetas perforadas (16) a 30 traves de las que recibe el rodillo (17) de manera articulada, este rodillo se forma como si fuera una bandeja con lenguetas (18) complementaria a las lenguetas anteriores para el paso de los respectivos ejes giratorios (19) formados como tornillos asistidos por cojinetes, y de manera simultanea tiene en su extremo opuesto y en la parte inferior, otras lenguetas The second part (3) of the seat base incorporates a pair of perforated tabs (16) through 30 which the roller (17) receives in an articulated manner, this roller is formed as if it were a tray with tabs (18) complementary to the previous tongues for the passage of the respective rotating shafts (19) formed as bolts assisted by bearings, and simultaneously has at their opposite end and at the bottom, other tabs
(20) que, con la ayuda de un pivote (21), permite fijar dicho rodillo (17) al extremo libre del cilindro neumatico (6), tal y como se puede observar en la Figura 6. (20) which, with the help of a pivot (21), allows said roller (17) to be fixed to the free end of the pneumatic cylinder (6), as can be seen in Figure 6.
El rodillo (17) forma una especie de bandeja abierta por su extremo superior, provisto en las partes inferior y frontal de dos aperturas laterales (22), en las que se atornillan las respectivas almohadillas (23) a los resaltes de desplazamiento (24) de la parte de la base (1), de manera que el rodillo (17) se puede deslizar en direcci6n delante-detras y se puede fijar en la posici6n que se desee y, como se vera mas adelante, mediante una cremallera lateral (25) y su correspondiente elemento de bloqueo. The roller (17) forms a kind of open tray at its upper end, provided in the lower and front parts of two lateral openings (22), in which the respective pads (23) are screwed to the travel projections (24) of the base part (1), so that the roller (17) can slide in the front-to-back direction and can be fixed in the desired position and, as will be seen later, by means of a side zipper (25 ) and its corresponding blocking element.
El rodillo (17) incorpora, en correspondencia con su eje longitudinal imaginario, un soporte frontal (26) con un agujero (27) para acoplar un pasador largo (28) sobre el que se ensambla un muelle helicoidal (29) contra el que se puede mover el rodillo; dicho pasador presenta un engranaje helicoidal (30) sobre el que actua un perno (30�) que se extiende en una varilla lateral (31) y acaba, a su vez, en un mando (32); este ensamblaje se fija con la ayuda de una tapa atornillada (33). Con este sistema de engranaje, la longitud real del muelle (29) y, en consecuencia, la potencia que debe alcanzarse para lograr el movimiento del asiento, se podra duplicar, si se desea. The roller (17) incorporates, in correspondence with its imaginary longitudinal axis, a front support (26) with a hole (27) for coupling a long pin (28) on which a helical spring (29) is assembled against which can move the roller; said pin has a helical gear (30) on which a bolt (30�) acts which extends in a lateral rod (31) and ends, in turn, in a control (32); This assembly is fixed with the help of a screwed cover (33). With this gear system, the actual length of the spring (29) and, consequently, the power that must be achieved to achieve the movement of the seat, can be doubled, if desired.
La caja exterior (34) del asiento se ensambla al rodillo (17), estando provisto el asiento de un hueco amplio (34') opuesto al receptaculo configurado por el rodillo (17), al que se fija mediante tornillos (35) que se deslizan sobre unas guias o ranuras longitudinales (35') que permiten la movilidad de dicha caja o del asiento en relaci6n al rodillo y frente a la tensi6n del muelle (29). Esta caja (34) dispone, en los lados, de una acanaladura (36) con un muelle The outer box (34) of the seat is assembled to the roller (17), the seat being provided with a wide recess (34 ') opposite the receptacle configured by the roller (17), to which it is fixed by screws (35) which is they slide along longitudinal guides or grooves (35 ') that allow the mobility of said box or of the seat in relation to the roller and against the tension of the spring (29). This box (34) has, on the sides, a groove (36) with a spring
- (37) (37)
- en su parte inferior, sobre la que se ensambla con caracter giratorio contra dicho muelle in its lower part, on which it is assembled with a rotating character against said spring
- (37) (37)
- un mando (38) que se introduce en el hueco (34') de la caja y acaba en una especie de peine (39) para bloquear el asiento respecto al rodillo, a traves de la cremallera (25) de esta ultima. a control (38) that is inserted into the recess (34 ') of the box and ends in a kind of comb (39) to block the seat with respect to the roller, through the rack (25) of the latter.
Un cuerpo almohadillado (40) que constituye la superficie del asiento colocado sobre la caja (34), dicho cuerpo incorpora, de manera perimetrica, acoplamientos de ajuste (41) en la parte inferior; dichos acoplamientos se encajan de forma machihembrada haciendo presi6n en los enganches complementarios (42) de la caja (34). A padded body (40) constituting the surface of the seat placed on the box (34), said body incorporates, perimetrically, adjustment couplings (41) in the lower part; said couplings are tongue and grooved, pressing on the complementary hooks (42) of the box (34).
Por ultimo, debera indicarse tambien, tal y como se muestra en las Figuras 17 y 18, que el respaldo (44) se fija mediante un par de pasadores (43) al extremo frontal elevado de la parte (3) que se encuentra en la base del asiento; el respaldo, por tanto, se une de manera rigida a la estructura de la base del asiento en su parte m6vil, pero es independiente fisicamente del asiento en si. Finally, it should also be indicated, as shown in Figures 17 and 18, that the backrest (44) is fixed by means of a pair of pins (43) to the raised front end of the part (3) found in the seat base; The backrest, therefore, is rigidly attached to the structure of the seat base in its mobile part, but is physically independent of the seat itself.
