Definitions
- the invention relates to a chair mechanism for adjusting the seat and the backrest with the features of the preamble of claim 1.
- the components forming the armchair mechanism are predominantly designed as welded steel structures. These steel structures, which are usually not aesthetically pleasing, are often covered by and taken up by a large plastic shell, which is attached to the underside of the seat plate. These spacious plastic shells make the armchair appear heavy and chunky.
- FIG. 1 shows a side view of an armchair mechanism and FIG. 2 shows a side view of the base part; Figures 3 and 4 bottom and top view of the lower shell of the base part. 5 and 6, the top and bottom view of the upper shell of the base part
- a base part 1 which is mounted at the upper end of a vertical post 2 of a conventional type of chair foot, not shown here, and can be rotated about its vertical axis.
- This base part 1 protrudes laterally from the upright 2, and on the freely projecting front are arranged pivotable about a horizontal axis handlebars 5, which in turn are connected to the front of a plate-shaped carrier 6, which receive the seat plate, which is not shown here Has.
- the seat plate can be slidably mounted on this support 6.
- This connection between handlebar 5 and bracket ger 6 is also hinge-like, and the axis 7 of this hinge-like connection is parallel to the axis 4.
- the rear side of the carrier 6 is hinged about the axis 9 by means of a linkage 8 connected to the base part 1, the linkage 8 on the base part 1st is also hinged and the axis 10 of this hinge-like connection is close to the vertical post 2.
- the to the rear - in Fig. 1 to the right - projecting linkage 8 carries the backrest, not shown here.
- the chair mechanism discussed above is a synchronous chair mechanism, which means that the seat and backrest can be adjusted together, but by different angles.
- a spring 11 is provided, which - seen from above - lies in the central section of the base part 1 and one end of which can be fixed to a bolt forming the pivot axis 7 and the other end of which can be fixed to one Supports support bolt, the axis 12 is in the same plane as the axes 4 and 10 of the hinge-like linkages.
- this spring is not shown, which, moreover, is designed so that it can be adjusted with regard to its respective active force.
- this is a combination of springs, consisting of a mechanical coil spring and an air spring passing through it in the middle.
- a lever (not shown here) is to be provided.
- FIG. 2 now shows the base part 1 from the side as in FIG. 1, the components described above being removed.
- This base part has a top or bottom view (FIGS. 3 to 6) of a V-shape with two legs 13 and a web 14 connecting these legs 13.
- This base part 1 consists of two shells, namely a lower shell 15 and an upper shell 16, which can be made of die-cast aluminum, for example.
- the parting plane 17 of these two shells 15 and 16 passes through the web 14 and the two legs 13.
- the axes 4, 0 and 12 lie in this parting plane.
- a bore 18 with a larger diameter provided in the web 14 receives the upper end of the vertical post 2. Furthermore, a groove 19 which is open on both sides is provided in this web 14 and serves to receive a bearing pin which forms the axis 10. The linkage 8 is articulated on this bearing pin with the axis 10.
- one-sided open, channel-like and paired recesses 20, 21 and 22 are provided, which are cylindrical and which serve to receive bearing bolts and support bolts. These bearing and support bolts are indicated here by dashed lines. These recesses 20, 21 and 22 provided to form the bearings are formed in the legs 13 of the shell 15.
- the upper shell 16 (FIGS. 5 and 6) has a contour that is congruent with the lower shell 15; here too, recesses 20, 21 and 22 are found with the shell 15 in a congruent position. These recesses form when the shells 15 are screwed together and combined and 16 bearings for receiving the ends of the bearing bolts and support bolts, which are symbolized here by dashed lines.
- the free ends of the respective legs 13 are designed like a fork. In the extensions 24 of this fork-like design, the above-described paired depressions 20 and 21 are located.
- the bearing or support bolts are inserted into the recesses 20, 21 and 22 in one of the two upwardly open shells, for example the shell 16, v / obei the bearing bolts provided on the free ends of the legs 13 initially with the Handlebars 5 are equipped - By designing and shaping the depressions 20, 21 and 22 described here, these bearing and support bolts are clearly and securely positioned.
- the second shell 15 is now placed on the thus prepared shell 16 and then the two shells 15 and 16 are connected by means of screws which are received by the bores 23.
- the two congruent channels 19 in the web 14 then form a continuous cylindrical bore for receiving a bearing pin to which the linkage 8 is articulated.
- the base part 1 designed in this way thus gives the viewer a closed impression, since no front ends of the bolts can be seen and for this reason no arrangement must be provided to secure the bolts in position.
- the links 5 are arranged in the fork-like formations of the free ends of the legs 13 between the extensions 24 forming the fork.
- the bore 25 visible in FIG. 2 in the base part 1 serves to receive an actuating lever with which, for example, the spring can be influenced. Due to this closed construction of the base part, there is no need to arrange a large and bulky cover that prevents the chair mechanics from being seen.
