Definitions
- the invention relates to a synchronous mechanism for the simultaneous seat surface and backrest swivel movement in office chairs with the im
- the synchronous mechanism is usually in by a spring arrangement Direction of the basic position, i.e. against the swiveling movement backwards applied.
- spring arrangements can be of various types Have springs, such as leg springs, gas springs or Helical compression springs. The latter are usually between a fixed one Abutment on the seat support and one coupled to the backrest support Abutment clamped, whereby the latter when pivoting the compression spring must compress.
- That of the spring arrangement against the actuation of the synchronous mechanism back pressure to be applied should be adjustable for ergonomic reasons because a lighter person needs far less back pressure than a heavier one.
- such spring arrangements have suitable ones Spring force adjustments of various types. So will in the case of leg springs, for example, one of the legs is adjustable, so that the spring force is biased by shifting this leg can be.
- the disadvantage here is that when adjusting the preload must be worked against the full spring force.
- the object of the invention is a synchronous mechanism with spring loading and spring force adjustment arrangement so that the adjustment is practically “force-free”, So without having to work directly against the bias of the spring can.
- control mechanism mentioned for the positioning of the articulation axis formed a rack and pinion drive, so that by self-nomination of this Get the set spring force characteristics reliably remains.
- the seat support is as continuous thin-walled aluminum die-cast part with a vertical Cross-section formed H-shaped base profile, the H-vertical leg each of a substantially continuous side wall and its H-horizontal leg of functionally adapted cross ribbing are formed. There are from the peripheral edges of the two side walls peripheral cheeks in opposite directions. This profiling and training of the seat carrier can be extreme high rigidity of this component can be achieved in particular in the longitudinal direction. Thin-walled strengths of the die-cast part are sufficient throughout in the order of 3 mm.
- Another advantage is that the from the all-round edge cheeks on the outside of the two side walls enclosed space as an assembly space, for example for the spring arrangement, can serve. Due to the border with the cheeks can easily cover the entire kinematics from the outside a simple cover can be snapped on, only the right one Breakthroughs for axes and actuators, such as. B. the Rotary handle for actuating the control mechanism for spring force adjustment, must have.
- an office chair designated as a whole by 1 has a chair column 2 on which a seat support 3 with a cone seat 4 is placed. There is a seat plate 5 on the seat support at the front end articulated, only a simple swivel joint 6 being shown in FIG. 1 is.
- the backrest support 7 holds the actual one Backrest 9 and is also articulated with the seat plate via a handlebar 10 connected. It should be noted that instead of the shown Construction also a handlebar at the front end of the seat plate and rear a simple articulated coupling between the seat plate and backrest support can be made. The kinematic relationships are reversed compared to FIG. 1.
- FIG. 1 a spring arrangement designated as a whole by 11 is also indicated, their exact structure with reference to the other figures is explained.
- This spring arrangement 11 acts to pivot the from the seat support 3, seat plate 5 and backrest support 7 formed synchronous mechanism towards the bottom back (arrow 12) and acts on the Synchronous mechanism in the direction of the basic position shown in Fig. 1.
- the seat support 3 is parallel to the plane of the sheet 1 lying central longitudinal plane is symmetrical, that means that the spring arrangement visible in FIG. 11 on the outside of the Seat support 3 symmetrically on the opposite side of the seat support 3 is available again. In this respect, all are in the following as individual parts described components of the spring arrangement in pairs on both sides of the seat support available.
- FIGS. 2 to 6 Reference wherein in the perspective representations according to 3 to 6 the actual seat support 3 omitted for the sake of clarity is.
- the core of the spring arrangement 11 is one in FIGS. 2 to 6 as a cylinder indicated, rigid coil compression spring 13, which in a fixed Abutment 14 on the axis forming the swivel joint 6 of the seat plate 5 15 is articulated. So that the abutment 14 is pivotable, but effective as a fixed support point with regard to the synchronous mechanism.
- the opposite End of the helical compression spring 13 sits in a variable adjustable abutment 16, which is designated as a whole by 17 Spring force adjustment arrangement in a manner to be explained in more detail with the Backrest support 7 is coupled.
- the spring force adjustment arrangement 17 integrated in the spring arrangement 11 now has as its central part an approximately quarter-circular side view Bearing block 18 on the pivot axis 8 of the backrest support 7 is rotatably mounted. This is due to the hexagonal cross section the pivot axis 8 in Fig. 3 to 6 indicated.
- the backrest support 7 is also rotatably connected to the pivot axis 8, so that a Forced coupling based on the swiveling movement between the backrest support 7 and bearing block 18.
- the bearing block 18 as one Art carrier designed for a variety of functional parts by its area surrounding the pivot axis 8 two parallel, the mentioned Sidewalls 20, 21 defining quarter-circle shape protrude between which is virtually a mounting space 22 is formed.
- An abutment link 19 now runs in this assembly space an axis 23 is articulated to the variable abutment 16.
- the end of the abutment link 19 facing away from the abutment 16 is via a further (articulation) axis 24 in a sliding guide 25 slidably guided.
- This sliding guide 25 is an elongated hole guide trained, the somewhat curved, elongated backdrop essentially vertically and thus transversely to the direction of compression spring K runs.
- the sliding guide 25 is basically that of the compression spring 13 opposite end of the abutment link 19 so that the lever application point of the spring force defined by the axis 24 Bearing block 18 is variable in its distance from the pivot axis 8.
- This Rack and pinion drive 27 for the axis 24 and thus the position of the abutment link 19.
- This Rack and pinion drive 27 consists of a pinion 28 which is on a Bearing block 18 rotatably mounted actuating shaft 29 is seated. This is over a rotary handle not shown in the drawings rotatable by hand.
- the pinion 28 meshes with a rack 30, which is essentially transverse to the direction of action of the compression spring in a bearing block Linear guide 30 is guided.
- the bottom in Fig. 2 the toothed rack 30 is an elongated eyelet which is cranked laterally towards the axis 24 32 formed, the pivot axis 24 of the abutment link 19th receives.
- an additional support lever 33 in a parallel to the previously mentioned Axles extending further axis 34 pivotally mounted. Its opposite end carries the axis 23 already mentioned, which the joint between the variable abutment 16 and the abutment link 19 Are defined.
- the support lever 33 In the undeflected basic position shown in FIG The synchronizing mechanism, the support lever 33 is positioned such that it on the bearing block 18 via a contact area which is circular in side view 36 is non-positively. So that the spring force of the Helical compression spring 1 loaded directly onto the bearing block 18 and the Control mechanism 26 relieved in the interior.
- the mode of operation of the spring force adjustment can be explained with reference to FIG. 2 become.
- the control mechanism 26 is shown in one position there, in which the articulation axis 24 has a maximum distance A from the pivot axis 8 having.
- This pivoting movement is transmitted to the bearing block 18 and leads there for pivoting through the angle W.
- the articulation axis 24 passes through the circular arc path X1, which is essentially the compression path corresponds to the helical compression spring 13.
- FIG. 5 can be parallel to the helical compression springs 13 a central gas spring 37 is used, the piston rod 38 is connected to the axis 15. The end facing away from it the gas spring 37 is on the bearing block 18 via the approach recognizable in FIG. 5 39 struck so that the gas spring 37 in the same sense as the Helical compression spring 13 acts. In addition, it causes a damping of the entire kinematics and can block the pivoting movement synchronous mechanics. All that is needed is the arranged at the front end of the piston rod 38 trigger button 40 Gas spring can be operated in a known manner, so that the synchronous mechanism is switched rigid.
- the seat support 3 is a continuously thin-walled Die-cast aluminum part formed, one in vertical cross section has an approximately H-shaped basic profile.
- the H vertical legs are from the respective continuous side walls 50, 51 formed between is connected by integrally molded functional cross ribs 52 are.
- An example of the short-cut cone holder is shown in FIG. 7 4 in the lower area of the seat support 3 as transverse ribbing 52.1 to call.
- a horizontal transverse rib 52.2 can be seen at the top.
- peripheral edges 53 of the side walls 50, 51 are each in directions facing away from each other from the side walls 54, 55 serve to significantly stiffen the entire arrangement. on the other hand they delimit an assembly room in which, for example, part of the Spring assembly 10 can be accommodated. This is on the left in Fig. 7 Part indicated by the large number of lines superimposed.
- the seat support 3 can be provided on both sides with a simple cover shell 56, 57 are covered, which are shown in dashed lines in Fig. 1, oblong Breakthroughs 58, 59 for various actuators, such as the actuating shaft 29.
