Definitions
- the invention relates to a synchronous mechanism for a correlated seat-backrest movement of an office chair, with a placeable on a chair column base support, a seat or seat support and a backrest support.
- synchronous mechanism assemblies are understood in the seat base of an office chair, which provide for a mutually coupled, a certain relative movement of the seat and backrest with each other bringing kinematics.
- a base support is placed on a chair column, on which on the one hand a pivotable about a transverse axis, hingedly connected to the base support seat support and on the other hand also pivotable about a transverse axis, hingedly connected to the base support backrest support are mounted.
- On the seat support of the usually provided with a padded seat seat of the office chair is mounted.
- the backrest support which extends in a conventional manner from the actual synchronizing mechanism to the rear, carries on an upwardly extending arm, the backrest of the office chair.
- Seat support and backrest support are coupled so articulated that a pivoting movement of the backrest to the rear - as it can be caused for example by leaning of the chair user to the backrest - induces a lowering movement of the rear edge of the seat down.
- This correlated seat-back movement provides a significant comfort advantage and is desirable for orthopedic reasons.
- Such a synchronous mechanism is from the DE 101 25 994 A1 known.
- the seat support is connected to the base support via a structurally complex arm assembly in the form of a four-bar chain.
- a comparatively large tilt angle of the backrest is achieved.
- a comparatively large lowering movement of the seat is achieved by a constructive solution even with a relatively large backrest swivel angle, since seat support and backrest support are pivotally mounted in several points on the base support.
- Object of the present invention is to provide a structurally simple synchronous mechanism.
- a synchronous mechanism according to claim 1.
- the pivotable about a transverse axis backrest support is connected to both the base support and with the rear end portion of the seat or seat support directly hinged, so that a pivoting movement of the backrest to the rear induces a lowering movement of the rear portion of the seat support.
- the pivotable about a transverse axis seat or seat support is pivotally connected to the base support, so that the lowering movement of the seat support a horizontal Sliding motion is superimposed to the rear. Due to the direct connection of the backrest support to the base support and seat or seat support, it is possible to simplify the synchronous mechanism significantly constructive.
- a complex handlebar assembly for example in the form of a four-bar chain deleted. Nevertheless, thanks to the design of the synchronous mechanism according to the invention the achievable seating comfort comparable with the structurally more complex synchronous mechanisms.
- the ratio of the horizontal component x of the joint spacing to the vertical component y of the joint spacing in the basic position is between 0.6 and 1.7. Particularly advantageous is a ratio between 1.0 and 1.2.
- the ratio of the horizontal component x of the joint spacing to the vertical component y of the joint spacing in the maximum rearwardly pivoted position is between 2.8 and 5.8. Particularly advantageous is a ratio between 3.5 and 3.9.
- the ratio of the lowering angle of the seat or seat carrier to the pivoting angle of the backrest carrier is between 1: 2.1 and 1: 3.0.
- Particularly advantageous is a ratio between 2.5 and 2.7.
- connection of the seat or seat support takes place on the base support via a rotary-sliding joint.
- the horizontal sliding movement of the seat or seat support to the rear can be realized particularly simple and robust.
- a locking mechanism arranged in the front seat area for locking the position of the seat support to the base support intended.
- a spring assembly for biasing the synchronous mechanism, wherein the spring assembly comprises a leg spring whose one leg is supported on a seat or seat support arranged counterpart such that the position of the Anlenkicas and thus changed the spring property of the leg spring at a pivoting of the backrest.
- a particularly easy adjustment of the bias of the synchronizing mechanism is finally possible if a worm gear is provided for actuating the adjustment mechanism for the leg spring.
- the synchronous mechanism 1 has, as in Fig. 1 shown, a base support 2, which is set by means of a cone seat 3 on the upper end of a chair column (not shown), as also in the DE 101 25 994 A1 is shown.
- the synchronous mechanism comprises a substantially frame-shaped seat support 4 and a fork-shaped in plan view backrest support 5, the cheeks 6, 7 are arranged on both sides of the base support 2.
- the seat provided with a padded seat (not shown) is mounted.
- T-shaped guide elements 9 are arranged on the upper side 8 of the seat support 4 in cross-section, which serve for longitudinal displacement of the seat.
- a seat which is rigidly connected to the seat support 4. If a seat displaceable relative to the seat support 4 is used, the position of the seat can be changed in a simple manner at the factory by changing the position of the guide elements 9 on the seat support 4, for example in a particularly simple manner in that the Guide elements 9 are bolted to a different position on the seat support 4.
- On the side frame members 10 of the seat support 4 a number of seat longitudinal direction L successively arranged locking lugs 11 are provided, which also serve in a known per se and unspecified manner of positioning and mounting the seat on the seat support 4.
- a backrest On the backrest support 5, a backrest, not shown, is attached, which is height adjustable in modern office chairs.
- the backrest may also be integrally connected to the backrest support 5.
- the backrest support 5 is connected on the one hand with the lower, forwardly directed end 12 of the cheek 6 with the base support 2 directly articulated.
- the lower end 12 of the cheek 6 is mounted on a pivot bearing 13 on the base support 2 such that the backrest support 5 is articulated via the pivot bearing 13 in something centrally directly on the base support 2.
- the backrest support 5 can be pivoted with the backrest about the pivot axis 14 extending through the pivot bearing 12 in the pivoting direction S.
- An additional connecting element for example an intermediate link between backrest support 5 and base support 2, is not provided.
- the backrest support 5 is connected to the upper end 15 of the cheek 6 via a joint 16 with the seat support 4 at its rear end region 17.
- the seat support 4 is taken and lowered in the pivoting direction S.
- Fig. 1 shown basic position of the backrest support 5 extends through the hinge points 13, 16 extending longitudinal axis 18 of the pivot mechanism obliquely inclined backwards.
- the ratio of the horizontal component x of the joint spacing A to the vertical component y of the joint spacing A corresponds to approximately 1.1.
- the longitudinal axis 18 encloses an angle W1 of slightly more than 40 ° with the seat carrier plane E lying essentially horizontally in the basic position.
- FIG. 3 illustrated front view schematically shows the position of the sectional illustrations. It is both a cut ( Fig. 5 ) along the median plane M and another section ( Fig. 4 ) are shown along a plane offset laterally parallel to the plane M.
- the seat support 4 is connected at its front end portion 21 with the base support 2 via a rotary-sliding joint 22.
- This consists on the one hand of a connected to the seat support 4 sliding member 23, which rests on the other hand in a sliding guide, which is formed by two spaced-apart sliding blocks 24, 25, which are firmly connected to the base support 2.
- the upper sliding block 25 abuts against a stop 26 on the seat carrier 4. This avoids that the seat support 4 performs over the substantially horizontal basic position also extending pivotal movement forward.
- Both sliding blocks 24, 25 have spherical guide surfaces 27, which allow the sliding member 23 and thus also with the connected in the sliding member 23 seat support 4 and the pivoting movement can be traced back down.
- the backrest support 5 Due to the shape of the backrest support 5 and its arrangement of the base support 2 and seat support 4 performs under load the backrest on the one hand, the backrest support 5 a pivoting movement in the pivoting direction S back down. By the pivoting movement but also the seat support 4 is pivoted both backwards down and moved horizontally in the region of the rotary sliding joint 22 to the rear. This results in no relevant lifting movement of the front end of the seat, which constrictions are avoided on the underside of the thigh.
- the latching mechanism 30 comprises on the one hand on the underside 31 of the seat support 4 in the longitudinal direction L successively arranged locking grooves 32 and on the other hand arranged in the base support 2 substantially cuboid locking wedge 33, which is designed to engage in the locking grooves 32.
- the locking wedge 33 is guided in a guide channel 34 and is connected at its lower end with a wire spring 35 which is actuated via a pivot lever 36 in a manner not shown. In the locking position of the locking wedge 33 is through the wire spring 35 is biased in the direction of locking groove 32, so that a secure engagement in the locking groove 32 is ensured.
- the wire spring 35 is guided downward, whereby an active return of the locking wedge 33 takes place from the detent position.
- the free end of the locking wedge has a mushroom-shaped in cross-section wedge end 37, with which it rests in the locking groove 32.
- the tapered contact surfaces of the wedge end 37 ensure a secure locking in the locking groove 32, even with pivoted seat support. 4
- L locking grooves 32 There are several consecutively arranged in the longitudinal direction L locking grooves 32 are provided.
- the synchronous mechanism is therefore detectable in various intermediate positions between the basic position and the maximum rearwardly pivoted position.
- the arranged opposite the pivot lever 36 operating lever 38 serves to trigger the height adjustment of the chair column.
- the synchronizing mechanism 1 is biased by a spring arrangement counter to the pivoting direction S - ie to the basic position of the synchronous mechanism out.
- This spring arrangement is in the form of two leg springs 41 which are aligned with one another in the transverse direction, cf. Fig. 7 ,
- the upwardly pointing leg 42 is supported on a projection on the seat support 4, while the second, forwardly extending leg 43 is supported in an adjustment mechanism in the base support 2.
- the torsion springs 41, 41 'exert a spring force against the rearward pivotal movement of the backrest, which is variable by the adjustment mechanism by means of actuation by a rotary lever 44.
- the adjustment mechanism comprises a connected via a shaft 45 with the rotary lever 44 worm 46, wherein the shaft 45 rests in bearing shells 47 in the base support 2, see. Fig. 6 ,
- the rotary lever 44 is disposed in the sleeve-shaped pivot lever 38 for the Gasfederauslect and is pulled out to operate the worm gear.
- the worm 46 engages with its teeth in a worm wheel 48, which is connected to a threaded rod 49.
- the threaded rod 49 is rotatably mounted at its two ends 52, 53 on the one hand in the cover 50 of the base support 2 and on the other hand in the base body 51 of the base support 2.
- the worm wheel 48 is rotated by the worm 46, and a spring prong 54 serving guide prism 54 is guided by the movement of the threaded rod 52 on the threaded rod 52 along. If the guide prism 54 is moved downward, the spring leg 43 extending forwardly is acted upon by the leg spring 41 and pushed away downwards, which leads to an increase in the pretensioning of the leg spring 41. This has the consequence that the pivoting movement of seat support 4 and backrest support 5 in the pivoting direction S takes place against a greater resistance.
- the upwardly facing second leg 42 of the leg spring 41 abuts against a second guide prism 55, which is arranged on the underside 31 of the seat support 4.
- the leg spring 41 is in other words floating on both sides.
- the pivot point of the upper spring leg 42 shifts.
- the position of the pivot point changes so under load the backrest such that the pivot point shifts towards spring center point 56. This will be a automatic change of the spring behavior of the leg spring 41 during a movement in the direction of pivoting S.
- the leg spring 41 and thus the seat as a whole automatically becomes harder.
- the backrest support 5 is fastened with fastening screws 57 on the central pivot axis 14.
- the diameter of the pivot axis 14 is selected such that the leg springs 41, 41 'do not rest on the pivot axis 14 in the cocked position.
- the inner diameter of the leg springs 41, 41 ' is always greater than the diameter of the pivot axis 14. This ensures unimpeded rotation of the pivot axis 14 upon pivoting of the seat. In addition, annoying contact noise, such as squeaking, avoided. Since the two mounted on the pivot axis 14 leg spring 41, 41 'lie with its circumference in a manner designed in the manner of a prism spring rest 58, the positioning of the leg springs 41, 41' still guaranteed safe in their operating position.
- leg springs 41, 41 ' By using leg springs 41, 41 'a direct transfer of the spring force to the synchronizing mechanism 1 is possible, so that additional components for power transmission are not required.
- the number of components required in total is also lower in comparison to known from the prior art synchronous mechanisms, since the adjustment mechanism is composed of relatively few components.
- the adjustment mechanism is also particularly robust and allowed because of the use of the worm gear due to their very high gear ratio, a particularly easy adjustment of the rotary lever.
- the seat support 4 is integrated in the seat of the seat.
- the seat of the seat is formed so that it is directly connected to the base support 2.
- a separate seat support is then no longer required.
- the seat thus receives a more filigree shape.
- the backrest support 5 is hinged directly to the rear end of the seat shell and also the base support 2 is connected to the front end of the seat shell via a sliding bearing or the like.
- the seat shell on two spherical plain bearings.
- the sliding member 23 is also part of the seat.
- the joint bearings and the sliding member 23 are molded integrally on the seat shell.
- the seat on the required locking mechanism for the locking grooves 32.
