Definitions

  • the invention relates to a chair, in particular an office chair, according to the preamble of claim 1.
  • a so-called synchronous mechanism known to be pivoted at the backrest and seat in a certain predetermined ratio simultaneously.
  • an energy accumulator in the form of a helical compression spring, by means of which a force is generated between the front seat support member and the rear seat support member which places the backrest in its front end position and the rear portion of the seat in its upper Position presses.
  • a so-called seesaw mechanism is given, that is, the user can bob against the restoring force of the backrest with the back.
  • the synchronous mechanism can be locked, so that no relative movement between the seat support parts can be done more.
  • a locking or locking the synchronous mechanism takes place in situations where the user does not want mobility of the backrest. If the lock is made in an upright position of the backrest, the resulting seating position may be felt by the user to be uncomfortable over time.
  • the seat mechanism described can be used as a synchronous mechanism and as a mechanism with permanently determined backrest.
  • the invention has for its object to offer a specially adapted to the needs of the user locking device.
  • the locking device provides a plurality of discrete locking positions of the seat support parts to one another. It is therefore possible to lock the synchronous mechanism as needed in a relatively upright or even in a comparison inclined position of the backrest.
  • more than two locking positions can be specified.
  • a stepless specification of locking positions by appropriate design of the locking device for example by a corresponding clamping mechanism possible.
  • This locking device can be realized constructively with little effort, wherein the locking device can withstand in the individual discrete locking positions and larger load forces. As a rule, some locking positions, for example four locking positions, are sufficient.
  • This locking device is also structurally simple and still safe.
  • the locking device according to claim 4 ensures that the bolt and the counter body in a change of Relative positions of the seat support members before locking their distance from each other do not change significantly, so that the stroke of the locking movement of the predetermined relative position between the seat support parts is substantially independent. This increases the ease of use of the locking device.
  • a certain relative position between the bolt and counter-body is assigned to a relative position between the two seat support parts. This increases the operating safety of the locking device.
  • the pivot axis between the components of the locking device, so the mating body and the latch can, but need not coincide with the pivot axis between the two seat support parts.
  • Fig. 1 shows an office chair with a chair frame 1. This is provided with a pedestal 2, which is supported by rollers 3 with respect to the ground. On the pedestal 2, a height-adjustable chair column 4 is attached, at whose upper end a seat support 5 is attached.
  • the latter is designed in two parts; it has a front seat support part 6, which is mounted on the chair column 4, and a rear seat support part 7, which is articulated above the chair column 4 by means of a pivotable about a pivot axis 8 pivot joint on the front seat support part 6.
  • a support tube 9 is fixed, which extends parallel to the pivot axis 8.
  • a seat 10 is supported just behind its front edge 11 from.
  • the support tube 9 therefore represents a front support section for the seat 10.
  • the seat 10 is supported in its rear region on a support shaft 12, which is mounted in the rear seat support part 7.
  • the support shaft 12 therefore constitutes a rear support portion for the seat 10.
  • a seat tilt adjustment device 13 is further arranged at the rear seat support portion 7, arranged.
  • a backrest height adjustment device 16 is provided Integral with the rear seat support member 7 . Integral with the rear seat support member 7 is a towering from this backrest support 14 is formed on which a backrest 15 is mounted. In order to adjust their height relative to the seat 10, a backrest height adjustment device 16 is provided.
  • the described embodiment of the seat support 5 with the arrangement of the seat 10 and the backrest 15 forms a so-called synchronous mechanism.
  • a force varying device generally designated 17, is provided, which will be explained in more detail below.
  • Part of the force-changing device 17 is an over the front seat support member 6 downwardly projecting adjusting nut 18, of the in Fig. 1 a freely rotatable cap 19 is visible.
  • the chair column 4 has the height adjustment of the seat support 5 with the seat 10 and the backrest 15 a known adjustable gas spring 21, the in Fig. 3 is shown in supervision.
  • the gas spring 21 is held in a clamping device 22 formed in the form of a cone 22 of the front seat support part 6 by clamping. From the gas spring 21 protrudes upwards a valve actuating pin 23, at its insertion into the gas spring 21 there existing valve is opened, whereby length adjustments of the gas spring 21 are possible.
  • Such gas springs are for example in the DE 18 12 282 C2 (equivalent to U.S. Patent 3,656,593 ) and described.
  • a two-armed valve actuating lever 24 is provided, which is pivotally supported against the pivot axis 8, such as in the DE 43 24 545 A1 is described.
  • a first lever arm 25 of the valve actuating lever 24 abuts against the valve actuating pin 23, while the second lever arm 26 via a from the DE 43 24 545 A1 known lever mechanism can be operated.
  • a pivoting of the rear seat support part 7 relative to the front seat support part 6 of the synchronous mechanism counteracts an energy storage 27, which in the illustrated embodiment is a prestressed helical compression spring 28.
  • an energy storage 27 which in the illustrated embodiment is a prestressed helical compression spring 28.
  • the energy accumulator 27 on a helical compression spring 28 passing through guide rod 30.
  • the helical compression spring 28 is supported against a sliding block 31 of the force variation device 17.
  • the sliding shoe 31 in turn abuts against a sliding surface 32 which is formed on a first, short lever arm 33 of the rear seat support part 7.
  • the lever arm 33 is formed integrally with the rear seat support part 7 and extends from the pivot axis 8 from substantially downwards.
  • the rear seat support part 7 is formed as an angle lever.
  • On the guide rod 30 of the sliding block 31 along the screw-compression spring 28 is displaceable.
  • At a the abutment 29 opposite adjusting portion 34 of the guide rod 30 engages the force changing device 17 at.
  • An adjoining the adjusting portion 34 connecting portion 35 of the guide rod 30 passes through the first lever arm 33 of the rear seat support member 7.
  • the connecting portion 35 is angled towards the rear seat support member 7.
  • the adjusting portion 34 of the guide rod 30 is therefore bent to the rear seat support member 7 and adjacent to the seat support 5.
  • Part of the force variation device 17 is an adjusting screw 36, which is pivotally connected to the adjusting section 34 of the guide rod 30 via a pivot joint with a pivot axis 37.
  • the adjusting screw 36 engages in the adjusting nut 18, the rotatable in a lower wall 38 of the front seat support member 6, but in the direction of the screw 36 is mounted immovably.
  • the adjusting nut 18 has a straight-toothed conical section 39.
  • the two cone sections 39, 40 thus form a straight-toothed bevel gear.
  • a rotation axis 43 of the adjusting screw 36 and a rotation axis 44 of the actuating rotary handle 42 are not aligned with each other, but intersect and enclose a right angle with each other.
  • the end portion 41 is rotatable in a side wall 45 of the front seat support member 6, but axially mounted to the rotational axis 44 of the actuating rotary handle 42 immovably.
  • the free end of the actuating rotary handle 42 is formed as an oval handle 46 with recessed grips 47.
  • the handle 46 has a central bore 48 which is closed at the free end of the handle 46 by a depressed cap 49. Inserted into the bore is a connecting screw 50 which supports the handle 46 at the end portion 41 of the actuating knob 42.
  • the sliding surface 32 is at least approximately on a circular arc portion whose center is formed above the axis of the pivot joint of the abutment 29, upon a rotation of the actuating rotary handle 42, a distance b between the pivot axis of the abutment 29 and the penetration of the axis of the energy storage changes 27 by the sliding surface 32 only slightly. Therefore, in such adjustments, the bias of the coil compression spring 28 practically does not change.
  • the force acting on the first lever arm 33 of the rear seat support part 7 by the helical compression spring 28 is thus not changed; it is only by changing the distance a between the axis of the energy storage 27 and the pivot axis 8 of the effective lever arm, that is, the total acting of the helical compression spring 28 on the rear seat support member 7 and thus on the seat 10 and the backrest 15 torque changed.
  • This torque is the smaller, the smaller the distance a and vice versa.
  • the adjusting forces to be applied to the actuating rotary handle 42 over the entire adjustment path of the sliding block 31 can be kept constant since frictional forces between the sliding block 31 and the sliding surface 32 and also the actuating forces of the mechanical coupling between the guide rod 30 and the actuating rotary handle 42 are virtually non-existent to change.
  • the locking device 50 comprises a bolt 51, which is articulated on the front seat support part 6 about a pivot joint with a pivot axis 52 pivotally.
  • the pivot axis 52 coincides substantially with that of the abutment 29.
  • the bolt 51 has a horizontally arranged locking bolt 53, which is secured to the bolt 51 and passes through it in such a way that it protrudes on both sides beyond the bolt 51 in the horizontal direction.
  • Part of the locking device 50 is a cooperating with the bolt 51 counter-body 54. This is articulated on the front seat support member 6 about a pivot joint pivot axis 55 pivotally.
  • the pivot axes 52, 55 are spaced apart and parallel.
  • the counter body 54 has two mutually spaced, parallel, vertical and perpendicular to the pivot axis 55 arranged plates 56. These have a rough approximation of a triangular shape, wherein the pivot axis 55 opposite side as a bar peripheral portion 57 approximately located on a circular arc portion whose center is formed by the pivot axis 55.
  • the width of the bolt receptacles 58 is complementary to the locking bolt 53 of the bolt 51 dimensioned such that the locking bolt 53rd essentially free of play can engage in a pair of bolt receptacles 58.
  • This engagement of the locking bolt 53 in the bolt receptacles 58 takes place such that in each case one of the two free ends of the locking bolt 53 engages in one of the two bolt receptacles 58 of the corresponding pair of bolt receptacles 58.
  • a connecting member 60 is articulated on the counter body 54 as a coupling element.
  • the pivot axes 55 and 59 are spaced apart and parallel.
  • the connecting member 60 is articulated on the first, short lever arm 33 of the rear seat support part 7.
  • the pivot axis 61 is in this case parallel to the pivot axes 8 and 59 and spaced therefrom.
  • the latch 51 can be actuated by means of a led out laterally from the support tube 9 operating handle 63 which in Fig. 1 is shown.
  • Fig. 7 shows the locking device 50 in a position in which the locking bolt 53 in the side view of Fig. 7 and 8th assigned to the leftmost latch receptacle 58 is assigned. In this position, the rear seat support member 7 is with the backrest support 14 in the most upright position.

  • the connecting member 60 therefore acts as a mechanical transmission member, which translates the pivoting of the counter body 54 in relation to the pivoting of the rear seat support part 7.
  • the locking device 50 is out of operation, so that a synchronous relative movement between the seat support parts 6, 7 is possible. If the user overrides the synchronous mechanism, ie, wants to lock the seat support parts 6, 7 against each other, he brings first by appropriate pressure on the backrest 15 and thus on the backrest support 14 on the rear seat support part 7 latter in a desired relative position Next, the user actuates the operating handle 63 and moves the latch bolt 53 toward the latch peripheral portion 57. The locking bolt 53 then comes either immediately with its adjacent bolt receptacle 58 into engagement or the user performs a fine adjustment of the seat support parts 6, 7 to each other by appropriate pressure on the backrest 15 until the locking bolt 53 engages in the corresponding pair of bolt receptacles 58.
  • the synchronous mechanism is locked in the desired relative position of the seat support parts 6, 7 to each other.
  • the connecting member 60 ensured by its translation function here that, despite not too low Distance of the bolt receptacles 58 in the circumferential direction of the bolt peripheral portion 57 to each other a fine gradation discrete relative positions of the seat support parts 6, 7 is given.

  • a tilting adjusting screw 75 is articulated via a pivot joint with also pivot axis 8, which is also parallel to the pivot axis 8. This is axially displaceable and rotatably mounted.
  • the inclination adjusting screw 75 engages in a tilt adjusting nut 76, which is rotatably mounted in a lower wall 77 of the rear seat support member 7, but immovable in the direction of the inclination adjusting screw 75.
  • the tilt adjusting nut 76 has a straight toothed conical section 78.
  • the ring gear of this engages a likewise straight-toothed conical portion 79 of an end portion 80 of a tilt-actuated rotary handle 81 a.
  • the two conical sections 78, 79 thus form a straight-toothed bevel gear.
  • An axis of rotation 82 of the adjusting screw 75 and an axis of rotation 83 of the tilt-actuating rotary handle 81 are not aligned with each other, but intersect and enclose a right angle with each other.
