Definitions

  • the invention relates to a synchronous mechanism for office chairs with the features specified in the preamble of claim 1, as is known from a variety of documents, such as DE 103 57 165 A1 in its basic structure is known.
  • 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, to which on the one hand a pivotable about a transverse axis, hingedly connected to the base support seat carrier and on the other hand a pivotable about a transverse axis, hingedly connected to the base support backrest support are stored.
  • 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 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.
  • a fundamental issue with synchronous mechanisms is their spring action against the pivoting backwards.
  • a variety of spring designs is known from the prior art.
  • the construction according to DE 101 25 994 A1 provided spring assembly is based on two torsion springs, which are housed in the base support.
  • the one leg of the spring is housed in an adjustment in the base support, whereas the second leg projects upwards in the direction of seat support, which is supported via a corresponding abutment on this leg and thus acted against its rearward pivoting direction.
  • the invention is therefore an object of the invention to provide a synchronous mechanism with an improved adjustment for the counter-spring force of the spring assembly, in which a high ease of use is ensured with constructive simplicity.
  • the adjusting arrangement is formed by a lock which can be introduced from one end of the at least one helical spring into its winding passages with a variable depth of engagement.
  • the coil spring is locked in the region of the winding paths acted upon by the barrier against a spring deformation.
  • the invention is based on the basic principle that by blocking windings of a coil spring, the remaining, non-blocked Windungserie for a given extension of the spring must deform more, so that a higher counter-spring force is generated, as if more or all Windungserie the coil spring are freely movable.
  • turns are literally "shut down".
  • the intervention of the lock takes place with a force that depends primarily only on the friction conditions between the lock and the Windungs Spotifyn, but not of the spring force itself.
  • - designed as a blocking block Lock can be screwed, for example, in the upright basic position of the synchronous mechanism under game in the Windungs Vietnamese, a very leich113e adjustment of the spring force can be achieved.
  • the barrier is formed by a plurality of locking members, such as locking balls, which are successively inserted between the winding turns of the coil springs.
  • Fig. 1 the synchronizing mechanism 1 as a supporting part on a base support 2, which is provided in the region of its rear end with a cone seat 3 for attaching the synchronizing mechanism to the upper end of the chair column 4.
  • Other basic components of the synchronizing mechanism 1 are the backrest support 5 and the seat support 6.
  • the backrest support 5 is located shortly before the cone seat 3 via an in Fig. 3 dash-dotted lines indicated, but not shown in detail in the drawings transverse axis 7 pivotally mounted on the base support 2. He has two back up-going side struts 8, 9, between them include a receiving plate 10 for mounting the backrest, not shown.
  • the base support 2 extends from the cone seat 3 in an arc forward above (see Fig. 1 and 2 ), where in its front end portion of the substantially flat, in plan view approximately rectangular pan formed seat support 6 is hingedly connected to its front end portion.
  • a designated as a whole with 11 rotary-sliding joint is provided, the detailed structure here need not be explained in detail, since this is not significant for the invention. It should be noted that with the help of the rotary sliding joint 11 of the seat support 6 in the longitudinal direction L is slidably mounted and pivotable about a transverse axis 12 on the base support 2.
  • a transverse axis 13 is provided in the seat support 6, to which the backrest support 5 via two each of the side struts 8, 9 upwardly projecting bearing cheeks 14, 15 is pivotally coupled.
  • Fig. 1 shows the synchronous mechanism 1 in its normal position in which the seat support 6 and thus the thereon (not shown) seat cushion unit substantially horizontally and the backrest support 5 are arranged so that also not shown, on the backrest support 5 fixed backrest is substantially upright.
  • the backrest support 5 is backwards down (clockwise in accordance with Fig. 1 and 2 ) is pivoted about the transverse axis 7.
  • the seat support 6 is pulled on the one hand over the transverse axis 13 to the rear bottom, simultaneously pivoted about the front transverse axis 12 and thus displaced in the rotary sliding joint 11 to the rear.
  • the three components base support 2, backrest support 5 and seat support 6 then take the in Fig. 2 shown position with reclined seat cushion unit and backwards tilted backrest.
  • the synchronizing mechanism 1 is subjected to a force by means of a spring arrangement designated as a whole by 16 against the synchronizing adjustment movement explained above.
  • This spring arrangement 16 has two symmetrical to the central longitudinal plane M ( Fig. 3 ) parallel to each other and to the seat surface arranged, open-wound helical compression springs 17, which in the following - like all other paired components - if necessary by the additional numbering ".1" or ".2" are distinguished.
  • the two helical compression springs 17 are supported by their front end 18 on a bearing block 19 in the seat support 6. With its rear end 20, the helical compression springs 17 are supported on the base strut 21 of a U-shaped counter-holder 22, which is connected to the free ends of its U-legs 23 pivotally connected to the base support 2 in the region of the rotary sliding joint 11.
  • the spring arrangement 16 is associated with an adjusting arrangement denoted as a whole by 24, which is accommodated in the seat carrier 6 on the side of the bearing block 19 facing away from the helical compression springs 17.
  • Core parts of this adjusting arrangement 24 are each one of the helical compression springs 17 associated locking blocks 25, which is substantially coaxial with the helical compression springs 17 arranged sleeve-like components with an external thread 26 and a lijnsaxial continuous guide channel 27.
  • the locking blocks 25 are each set to a coaxial with them and the helical compression springs 17 in the seat support 6 rotatably mounted rotary drive pin 28. How out Fig.
  • the rotary drive pin 28 engage with its outer contour and the guide channel 27 of the locking blocks 25 respectively by a nut and spring-like cross-sectional training rotatably in one another, so that a rotational movement of the rotary drive pin 28 is converted into a rotational movement of the locking block 25, the latter, however, in the longitudinal axial direction telescopically slidably mounted on the rotary drive pin 28.
  • the threads 29 of the external thread 26 of the locking blocks 25 in their pitch and cross-sectional shape are designed so that they are complementary to the Windungs réellen the helical compression springs 17 are.
  • the locking blocks 25 can screw in rotation in each case in the front end 18 of the coil springs 17, whereby the threads 29 engage between the individual winding turns 30 of the helical compression springs 17 and lock them against a spring deformation. Due to the threaded engagement between locking block 25 and helical compression springs 17 of the locking block 25 is quasi automatically drawn into the respective helical compression spring 17 when the locking block 25 is offset by means of the associated rotary drive pin 28 in a rotary motion.
  • This rotational movement of the rotary drive pin 28 is generated by means of the mounted in the horizontal transverse direction at the front end of the seat support 6 adjusting shaft 31 which is actuated by a handle 32.
  • the adjusting shaft 31 is coupled via a bevel gear 33 with a central gear 34, which in turn engages with two each seated on the rotary drive pin 28 Abriebszahnziern 35.
  • the adjustment assembly 24 is based on Fig. 3 to explain.
  • the associated locking block 25.1 is shown in its inactive position in which he retracted maximum forward on the rotary drive pin 28.1 and he just with one to two threads 29 in the front end 18.1 the helical compression spring 17.1 engages.
  • the entire helical compression spring 17.1 is thus available for deformation, resulting in a minimum counterforce.
  • FIG. 7 to 11 an alternative embodiment of a synchronous mechanism according to the invention is shown. This differs from the embodiment according to Fig. 1 to 6 In order to avoid unnecessary repetition, therefore, components of the two embodiments of the synchronous mechanisms that match, provided with identical reference numerals and it can in this respect to the Description of the synchronous mechanism 1 according to Fig. 1 to 6 to get expelled.
  • the adjustment assembly 24 'for the counter-spring force of the two coil springs 17.1, 17.2 existing spring assembly 16 has to block Windungs réellen 30 of the coil springs 17 as locking members acting locking balls 36 which are arranged in radial recesses 37 of a disposed within the coil spring 17 support sleeve 38 , Like from the Fig. 7 to 11 becomes clear, are provided over the circumference of the support sleeve 38 evenly three longitudinally extending rows of radial recesses 37, each with a locking ball 36.
  • the support sleeve 38 itself is fixed in the bearing block 19 of the seat support 6 with one end together with the corresponding front end 18 of the respective helical spring 17 and protrudes into the inner opening of this helical spring 17 approximately half the length.
  • the outer diameter of the carrier sleeve 38 substantially corresponds to the free inner diameter of the respective helical spring 17. Its wall thickness is smaller than the diameter of the locking balls 36, so that in a position where they do not protrude beyond the outer contour of the carrier sleeve 38, into the inner opening of the carrier sleeve 38 stand in (see Fig. 7 , 8th).
  • an actuating slide 40 which is displaceably mounted in the inner opening of the carrier sleeve 38 is provided which is divided in its longitudinal direction into a front release area 41, a rear stop area 42 and an intermediate conical transition 43.
  • the actuating slide is between a maximum of the support sleeve 38 pulled forward release position ( Fig. 7 and 8th ) and a maximum in the support sleeve 38 inserted blocking position ( Fig. 9 and 10 ) by one as a whole displaceable with 44 designated drive device.
  • This consists of the provided with a handle 32 adjusting shaft 31, as in the embodiment according to Fig. 1 to 6 Use finds.
  • a handle 32 adjusting shaft 31 as in the embodiment according to Fig. 1 to 6 Use finds.
  • This adjusting shaft 31 drives a circulating toothed belt 45 via a driven gear 46.
  • the toothed belt 45 is further on a Umlenk leopardrad 47 ( Fig. 8 and 10 ) and coupled via a transverse axis 48, each with a fixing eye 49 at the front ends of the actuating slide 40 with this.
  • a rotation of the adjusting shaft 31 is thus converted into a circulating movement of the toothed belt 45, which in turn leads to a displacement of the actuating slide 40 in the longitudinal direction L within the support sleeve 38.
  • the adjusting shaft 31 is actuated, so that over the toothed belt 45, the actuating slide 40 are gradually inserted into the support sleeve 38. It is thus successively pushed from the front end of the coil springs 17 ago the locking balls 36 via the conical transition 43 radially outward and between the Windungs réelle 30 of the coil springs 17. Through the blocking area 42 they are in fixed this blocking position. With increasing depth of engagement of the actuating slide 40 thus engage more and more locking balls 36 between the winding turns 30 of the coil springs 17, so that these respective Windungserie 30 are blocked. They are no longer available for a spring deformation, so that for a given deflection of the synchronous mechanism, the still free Windungserie 30 must be more deformed.
  • Fig. 9 to 11 show the maximum retracted position of the actuating slide 40, in which all the locking balls 36 engage radially outward between the corresponding winding turns 30 of the coil springs 17 and block them.
