Abstract
Description
- The present invention relates to an office chair, of the type structured on the basis of a rolling leg on which a seat-backrest assembly is assembled, which can be adjusted in height and in seat and backrest inclination in order to adapt to the specific requirements of each user.
- The object of the invention is achieve a marked asymmetry between the pivoting of the seat and of the backrest, such that the pivoting of the latter is of the order of four times greater than that of the seat, all of this maintaining the height of the front edge of the seat virtually unaltered so that in such pivoting operations there is no front level difference of the chair, which may give rise to the user's feet hanging in certain positions, and furthermore a positional adjustment of the seat in relation to the backrest as regards separation, all of this with a simple structure in which a single gas cylinder and a mechanical spring participate.
- Several office chairs with different mechanisms for the positional adjustment of their elements are known, including European Patent
EP 1 468 633 , in which the underframe of the chair is formed from a star leg and a central column allowing, with a gas spring, the upward/downward movement for the seat support, the mentioned seat being assembled in a pivoting manner on such support through its front area with the cooperation of intermediate link rods and a second gas cylinder, whereas at the rear part the backrest extends in lower arms bent obtusely forwards, which arms are articulated to the seat and are coupled to the mentioned seat support through their free end, and are also connected in said free end to the seat through mechanical springs - This solution has drawbacks that are mainly focused on the following aspects:
- The backrest accompanies the seat in its pivoting movements, which virtually occur with the same amplitude or with a very similar amplitude, such that pivoting which may be insufficient in a backrest entail excessive pivoting.
- The seat pivots through its front edge, such that from a position for the underframe and for the seat support, in which the front edge of the latter is suitable for the size of the user of the chair, said seat can move frontally downwards in an excessive manner or can rise making the user's legs hang, i.e. losing the contact with the floor, which is uncomfortable.
- The seat and the backrest are separated by a predetermined and invariable magnitude, which on many occasions it would be desirable to increase or reduce for greater comfort. Further state of the art documents are :

-
- The office chair proposed by the invention has been designed and structured in order to fully and satisfactorily solve the aforementioned drawbacks in each and every discussed aspect.
- To that end and more specifically, said chair is structured from the classic star leg, seat support and with height adjustment means for such seat, with the particularity that said seat support is formed as a base in which two articulated parts participate, one part corresponding to the seat and solidly connected in a non-removable manner to the rolling leg or column, and another part articulated to the first part, projected backwards and forming a markedly obtuse angle therewith, the second part being intended to receive the backrest.
- The first part incorporates a housing for a crosspiece finishing the rod of a gas cylinder, which crosspiece is fixed by means of a bridge-support suitably screwed to the base part, the other end of the gas cylinder being intended to be fixed to an upper runner, which will be discussed below.
- A control carrier is arranged and fixed by screwing on the first part of the mentioned base, which control carrier acts as a cover for said part, which is traversed by the gas cylinder and incorporates a lateral lever for acting on the gas cylinder.
- This lever acts on a lug of the gas cylinder, such that the latter acts continuously instead of working at regular intervals as is conventional, being blocked at any movement point for its piston upon acting on the mentioned lug thereof.
- A runner is assembled on the described assembly, which runner is articulated at its rear end by means of perforated tabs to the rear part of the base, whereas at its front end it is also articulated to the corresponding end of the gas cylinder, which runner incorporates at its front end area a pair of lateral openings in which respective sliding shoes solidly connected to the lower base move, such that at the level of this front end area the runner can only move horizontally but cannot change its height position in relation to the fixed base
- This runner further incorporates a lateral rack in which a sort of a pivoted comb can be selectively locked, which comb is assembled on the actual seat in order to allow the front-rear movement of said seat, as will be seen below.
- This movement is carried out against a robust spring arranged inside the mentioned runner, coaxially assembled on a sort of screw, the tension of which spring can be adjusted with the cooperation of a screw-nut transmission mechanism which can be externally actuated by means of another lateral control and through a rod traversing the also lateral wall of the runner.
- The actual seat is finally assembled by screwing on said runner, which seat is suitably padded and on the lateral wall of which, in an opening operatively arranged for that purpose, the mentioned pivoted comb for locking the rack is located.
- It must finally only be added that the backrest is fixed to the rear part of the base with the cooperation of a pair of screws, a maximum pivoting of 17 ° for said backrest having been provided, which is in turn accompanied by a maximum pivoting of 4 ° for the seat.
- To complement the description which is being made and with the aim of aiding to better understand the features of the invention according to a preferred exemplary embodiment thereof, a set of drawings is attached as an integral part of said description, in which the following has been shown with an illustrative and non-limiting character:
-
Figure 1 shows a perspective exploded view of the rear part of the type participating in the base corresponding to the seat of an office chair carried out according to the object of the present invention. -
Figure 2 also shows a perspective view of the assembly of the previous figure duly assembled and in a coupling situation with the other part of the base. -

Figures 9, 10 ,11 and 12 show respective perspective views of the assembly shown inFigure 8 in successive stages of incorporating the pressure control means of the mentioned spring to the runner. -
Figure 13 shows a perspective exploded view of the actual base of the seat, duly opposing the assembly of the previous figures. -
Figure 14 also shows a perspective view of the assembly ofFigure 13 duly assembled. -
Figure 15 shows a perspective view of the assembly ofFigure 14 in which the actual seat appears in an exploded view. -
Figure 16 shows a partial lower perspective view of the base part ofFigure 9 , at its lower face or the face for the coupling to the runner and in which the control for blocking the rack is disassembled. -
Figure 17 finally shows a perspective view of the assembly shown inFigure 11 , duly assembled, in contrast to that of said figure and next to which the complementary backrest appears. -
Figure 18 shows a general rear-lower perspective view of the entire seat. - In view of the indicated figures, it can be observed that the office chair proposed by the invention incorporates, at the level of its seat, a base structured by means of two parts, a fixed part (1) intended to be coupled to the star leg of the chair through a cylindrical bushing (2), and a moving part (3) which is joined in a pivoted manner to the fixed part (1) by means of bushings (4). Said fixed part (1) has a seat for the crosspiece (5) of a gas cylinder (6), which is fixed through said crosspiece with the cooperation of a bridge-part (7) anchored to the base part (1) by means of trilobular screws (8). These elements are covered by a sort of cover (9), really forming a control carrier, which is fixed in turn by means of screws (10) to the base part (1) and incorporates a pair of lateral controls (11-11'), the shafts (12) of which are tubular and wedged by means of a pin (13), said controls (11-11') having stops (14-14') for actuating on the frontal lug (15) of the gas cylinder (6) arranged in the base part (1) itself or on the gas cylinder of the support star leg, not shown in the drawings.
- The second part (3) of the base of the seat incorporates a pair of perforated tabs (16) through which it receives a runner (17) in an articulated manner, which runner is formed as a sort of tray having tabs (18) complementary to the previous tabs for the passage of respective pivoting shafts (19) formed as screws assisted by bushings, and simultaneously having at its opposite area and also at the lower part other tabs (20) which, with the cooperation of a pin (21), allow fixing said runner (17) to the free end of the gas cylinder (6), as especially observed in
Figure 6 . - The runner (17) forms a sort of tray open at its upper part, provided at its bottom and at its front end with two lateral openings (22), in which respective shoes (23) screwed to projections (24) of the base part (1) move such that the runner (17) can slide in a front-rear direction and can be fixed in any position chosen therefor and as will be seen below, by means of a lateral rack (25) and a blocking element therefor.
- The runner (17) incorporates, in correspondence with its imaginary longitudinal axis, a front bracket (26) with a hole (27) for coupling a long screw (28) on which there is assembled a helical spring (29) against which the runner can move, said screw having a helical gear (30) on which there acts a worm screw (30') finishing in a lateral rod (31) which is finished in turn in an actuation control (32), this assembly being fixed with the cooperation of a screwed lid (33). With this gearspindle system, the effective length of the spring (29), and subsequently the power that must be overcome to achieve the movement of the seat, can be doubled at will.
- The outer casing (34) of the actual seat is assembled on the runner (17), which seat is provided with a wide recess (34') opposing the receptacle configured by the runner (17), to which it is fixed by means of screws (35) sliding on longitudinal guides or grooves (35') allowing the mobility of said casing or actual seat in relation to the runner and against the tension of the spring (29). This casing (34) laterally has a channel (36) with a spring (37) at its bottom, on which there is assembled with a pivoted character against said spring (37) a control (38) penetrating the recess (34') of the casing and finishing in a comb (39) for blocking the seat in relation to the runner through the rack (25) of the latter.
- A padded body (40) configuring the surface of the actual seat is located on the casing (34), which body perimetrically incorporates snap-fit engagements (41) at the lower part, which engagements are fitted in a tongue and groove manner and under pressure in complementary engagements (42) of the casing (34) .
- It must finally and only be indicated, as shown in
Figures 17 and 18 , that the backrest (44) is fixed by means of a pair of long screws (43) to the raised front end area of the part (3) participating in the base of the seat, the backrest is thus rigidly joined to the base structure of the seat in its moving part, but is physically independent of the actual seat.
