Definitions

  • the invention relates to a swivel chair of the type specified in the preamble of claim 1.
  • DE-GM 84 17 429 discloses a "point synchronous adjustment device" with which this disadvantageous effect is to be avoided.
  • an elaborate and, above all, voluminous mechanism is provided under the seat, which also does not make the design of the chair or armchair appealing.
  • the invention has for its object to cope with the above-described problem of the "pull-out effect" with a relatively simple and compactly housed rocking or inclination adjustment mechanism.
  • the swivel chair according to the invention offers, by means of the rocking axes of the seat and backrest which are shifted far forward, an optimal synchronous movement to avoid the "pull-out effect" with space-saving and a completely new and stable chair design which enables the overall mechanism to be accommodated, in which no bellows to cover any crushing or shearing points is needed.
  • the supporting structure which consists exclusively of inexpensive steel pipes, serves as the base frame for an entire model family, i.e. from the typist's chair to the heavy executive chair.
  • the lower end of a support tube (3) which is bent at an obtuse angle is slidably and rotatably guided on a support tube (2) which is firmly connected to a base (1) of the swivel chair, a plastic bushing (4) being arranged between the support tube (2) and the support tube (3). is provided for guidance and additional support.
  • the standpipe (2) receives a gas pressure spring (6) on the inside in a plastic guide sleeve (5), which is supported at the bottom in the standpipe (2) on an axial pressure bearing (7) and with a cone (8) in a cone bushing (9 ) is seated, which is welded at (10) through a bore to the support tube (3) and at (11) with an insert tube (12) welded into the lower end of the support tube (3).
  • a cross tube (13) is firmly connected to the upper end of the support tube (3).
  • the support tube (3) and the cross tube (13) are cut out and welded together so that the clear cross section of both tubes (3, 13) is not constricted at any point by this connection.
  • the cross tube (13) runs perpendicular to the support tube (3) and lies horizontally.
  • a guide block (14) is fastened with screws (15) in the support tube (3).
  • a locking bolt (16) is slidably mounted, which engages in a toothed rack (19) for fixing an inclined position of a seat frame (17) and a backrest frame (18), which in the embodiment of FIGS. 1 and 2 is fastened to a crossbar (20) of the seat frame (17) and projects into the support tube (3) via an opening (21).
  • the toothed rack (19) has a longer tooth (22) at the free inner end, which abuts against it when the latching bolt (16) is withdrawn, so that the toothed rack (19) is not completely pulled out of the opening (21) of the support tube (3) can.
  • the release movement of the locking bolt (16) is limited by a leaf spring (23) which can be pushed away with a screwdriver or the like when dismantling the mechanism.
  • the locking bolt (16) is connected via a connecting rod (24) to a lever (25) on a shaft (26) which is mounted in bearing blocks (27, 28) within the left side of the cross tube (13) and one at the outer end Actuating lever (not shown here), which is accessible at the front left under the seat frame (17).
  • bearing blocks (27, 28) In the right side of the cross tube (13) there are further bearing blocks (29, 30) in which a further shaft (31) aligned with the shaft (26) is mounted, which shaft belongs to the actuating mechanism for the height adjustment of the chair.
  • a lever (32) at the inner end of the shaft (31) is connected via a connecting rod (33) to an angle lever (34) which is mounted at the rear end of the guide block (14) and which is accessible under the seat when actuated at the front right Actuating lever (35) (Fig. 2) presses on a tappet (36) of the valve of the gas pressure spring (6) to release it for height adjustment.
  • the seat frame (17) has bearing eyelets (37) on both sides at the front end, which are rotatably mounted on pins (38) that can be screwed into the outer bearing blocks (27, 29).
  • the axis for the pivot mounting of the backrest frame (18) in the bearing blocks (27-30) is formed by two torsion springs (39), each of which is fixed with a long spring leg (40) in an associated tube of the lower part of the backrest frame (18) .
  • bushings (41) are provided in these tubes, and the spring legs (40) have flats (42) on which clamping screws (not shown) engage.
  • the torsion springs (39) have shorter spring legs (43) which press against a stop block (44) designed as an adjusting nut, which at the front end of the support tube (3) with a knurled disc (45) is adjustable to the spring force the torsion springs (39).
  • the seat frame (17) and the backrest frame (18) are connected to one another on both sides by articulated brackets (46).
  • the exemplary embodiment shown in FIG. 4 differs from the exemplary embodiment according to FIG. 1 only in that the toothed rack (19) is fastened here to a crossbar (49) of the lower part of the backrest frame (18) and the latter to the seat frame (17) is connected via a rubber-metal buffer (50).
  • the torsion springs (39) are preferably made from round steel, but can also consist of leaf spring assemblies.
  • the upholstery of the chair, not shown, can be arbitrary, since the chair frame described and its mechanics, as mentioned at the beginning, serve as the base frame for an entire model family.
  • Fig. 5 shows in partial section a further embodiment of the swivel chair.
  • the locking bolt (16 ⁇ ) is under the force of a spring (51), which strives to insert the locking bolt (16 ⁇ ) in the rack (19).
  • a button (not shown here) for triggering the latch (16 ⁇ ) is designed as a latching button, ie when the button is pressed for the first time, the latch (16 ⁇ ) is pulled out of the rack (19) in order to be released again when the button is pressed a second time .
  • a locking device is used with a pawl (54) which can be pivoted in two planes under the force of a spring (53), as is customary in the case of locking switching buttons of electrical or electronic devices and therefore in detail need not be described.
  • the pawl (54) works together with a pin (55) on the locking bolt (16 ⁇ ).
  • the outermost ends of the torsion springs (39 ⁇ ) are positively connected to pipes (57) via coupling bushes (56) (see FIGS. 7 and 8), which transmit the torsional force in the direction of a spindle nut (44 ⁇ ).
  • Flattened ends (58) of the torsion springs (39 ⁇ ) are in corresponding flat bores (59) of the coupling bushes (56).
  • hooks (60) are attached, which engage in hook-shaped lugs (61) on the spindle nut (44 ⁇ ).
  • the pretension of the torsion springs (39 ⁇ ) can be adjusted by adjusting an adjusting spindle (62) seated in the spindle nut (44 ⁇ ) by means of a rotary knob (63).
  • the figures 9 to 11 show the adjustment mechanism for the prestressing of the torsion springs (39 ⁇ ) somewhat enlarged.
  • a rectangular housing-like extension (64) projecting forward is fastened to the cross tube (13 ⁇ ) and contains the adjusting spindle (62) and the spindle nut (44 ⁇ ).
  • the adjusting spindle (62) has an annular collar (65) on which an axial ball bearing (66) rests, which finds its other abutment on a substantially rectangular counter-pressure disc (67), which, as indicated by dash-dotted lines in Fig. 10, the installation of the Spindle (62) with nut (44 ⁇ ) and their own installation without screws and tools allows because the counter pressure plate (67) has an enlarged bore (68).
  • the counter pressure plate (67) With a flat recess (69), the counter pressure plate (67) is seated in a recess (70) of the housing-like extension (64) in the assembled state.
  • Fig. 12 shows i.a. the arrangement and design of an actuation button (73), which is mounted at one end (here at the right end) of the cross tube (13 ⁇ ), via a lever (74) with the shaft (31) already mentioned in the description of FIG. 2 in Connection is established and part of the operating mechanism for the height adjustment of the swivel chair.
  • the lever (74) protrudes through a slot (75) from the cross tube (13 ⁇ ), and the actuation button (73) has a beak-like extension (76) which covers the slot (75) in the rest position of the lever (74) and pinching injuries on fingers.
  • the seat frame (17) can also be tilted to a limited extent about an axis (77) when this tilting movement is released by the latching bolt (16).
  • the seat frame (17) is mounted on brackets (78) in front of the front upper edge of the cross tube (13 ⁇ ).
