Definitions
- the invention relates to an office chair with a vertical column starting from a base frame, a seat plate, a backrest and a cantilever projecting from the upper end of the column, at the front end of which the seat plate is supported in a first transverse pivot axis.
- Office chairs of this type are known in numerous embodiments.
- an office chair of the above type which is characterized in that a support mounted in the middle region of the arm in a second transverse pivot axis is guided underneath the seat plate to the backrest and carries the support on the column and / or the arm is resiliently supported and that the rear edge of the seat plate is slidably supported on the carrier.
- the function of such an office chair is essentially based on the pivotable support and a spring supporting the support on the column.
- the carrier supports the rear end of the seat plate and also the backrest and enables a simultaneous movement of these two parts when deflected in an ergonomically appropriate transmission ratio.
- a helical spring surrounding the column in its upper region is preferably provided.
- a sleeve is slidably mounted on the column, which extends from supported on top of the coil spring.
- the lower end of the coil spring rests on a support ring which is adjustable in height on the column and which can be designed as a screw ring which can be rotated on the column or comprises such a screw ring.
- the hardness of the coil spring can be changed by adjusting the height of the support ring.
- the sleeve and / or the support ring can have a helical recess on the mutually facing sides, which receives the respective end of the helical spring. In this way, the helical spring is secured in its position, and it is not necessary to bring the ends of the helical springs to the previous screw thread to form a flat support surface.
- the carrier is double-armed at least in the front and middle area of the chair and runs with one of the congruent arms along the outside of the boom and the column or the sleeve.
- the arms can converge in the rear area of the chair.
- the first transverse swivel axis which connects the arm to the front end of the seat plate, can be formed in a simple manner by rubber blocks, which allow sufficient deformation for the swivel movement of the seat plate and, moreover, have a damping effect.
- the only figure is a side view of a chair according to the invention.
- a pedestal 10 extends from a column 12 directed vertically upwards.
- a bracket 14 which is directed toward the front and is slightly inclined upwards.
- terms such as front, back, side, etc. refer to the normal sitting position of a person sitting on the chair.
- the pivot axis 16 can be formed, for example, by rubber blocks, which allow sufficient deformation in view of the relatively small pivot angle of the seat plate 18.
- a curved carrier 22 extends from the central region of the boom 14 in a second, horizontal, transverse pivot axis 20, which initially runs backwards below the seat plate 18 and then upwards to the rear of a backrest 24.
- the carrier 22 In the front and middle area of the chair, the carrier 22 is double-armed.
- one of the two congruent arms mounted in the pivot axis 20 runs on one side of the arm 14 and the upper end of the column 12. Behind the column 12, the two arms can converge again.
- the carrier 22 is resiliently supported in the area of the column 12 by a helical spring 26 surrounding the column.
- the helical spring 26 rests at its lower end on a support ring 28 surrounding the column, which in turn lies on a rotatable screw ring 30 surrounding the column and in threaded engagement therewith.
- the screw spring 26 is adjustable in height with respect to the column 12.
- the support ring 28 has on its upper side a helical recess 32 which receives the end of the coil spring 26. In this way, the helical spring is fixed in its position, and it is not necessary to process the last gear of the helical spring separately and to lead it to the preceding helical gear.
- a displaceable sleeve 34 which rests on the upper end of the coil spring 26.
- the sleeve 34 has a recess, not shown, for the passage of the boom 14 in the front region. Otherwise, the sleeve 34 has on its lower side a helical recess 36 which, like the recess 32 in the lower support ring 28, receives the outgoing end of the helical spring 26.
- the two arms of the carrier 26 run past the opposite outer sides of the sleeve 34 and are in one piece with the sleeve. ner third, horizontal, transverse pivot axis 38 pivotally connected. The carrier 22 is thus supported on the screw spring 26 via the sleeve 34.
- the rear end of the seat plate 18 is slidably supported on the support 22.
- the seat plate 18 and the backrest 24 are connected to one another in the region above the rear end of the seat plate 18 in a flexible connecting line 40.
- the rear region of the seat plate 18 is supported on the carrier 22 in a displaceable manner via a sliding guide 42. This gives the seat plate and backrest a certain degree of mobility with respect to the other parts of the chair mechanism, which on the one hand blocks the various movements of the chair mechanism and on the other hand provides a comfortable range of motion even when the chair is in a fixed position.
