Description

Chair, in particular office chair

The invention relates to a chair, especially an office chair, which is arranged on at least one seat, adjustable armrest.

From GB-A-2110925, a chair having an adjustable armrest is known. The latter is of flexible material and can be adjusted in an upper or in a lower layer. However, an individual height adjustment is not possible as her close - to suit users with different body sizes - would be desirable.

It is therefore an object of the invention to provide a new chair.

According to the invention this object is achieved by a chair, in particular an office chair having at least one is arranged on the chair arm rest having a Armauflageabschnitt and at least one extending downwardly from support portion, and with a device for height adjustment of this supporting portion. This is an easy height adjustment of the Armauflageabschnitts and therefore, an individual adaptation to the body size of the user possible.

With particular advantage to proceed in such a way that the armrest has two from Armauflageabschnitt downwardly extending support sections, one of which leads to a front portion of the chair and the other to a rear portion of the chair, and that at least one of these support portions to an apparatus for associated height adjustment. The result is a stable and reliable armrest with an easy way to adjust the height.

A very advantageous further development of this idea is characterized in that one of the support portions is connected via a joint to the adjoining it Armauflageabschnitt. One obtains a pivot point in the region of the transition to Armauflageabschnitt, so that the device for height adjustment on the other supporting portion can be easily formed. In this case the chair is formed in a further embodiment of the invention such that the support portion is provided with the joint is rigidly connected to the relevant area of ​​the chair. This makes the device very easy to adjust the height and does not require much effort.

The joint can be designed as a flexible portion of the armrest in a preferred manner, or as a pivot joint, and it is in a particularly preferred manner as before, that the other support portion extends in the region of the device for height adjustment of at least substantially concentric with this joint. This results in a technically safe while aesthetically pleasing design.

Another preferred embodiment is characterized in that the one support section is connected via a rotary joint to the corresponding region of the chair, where one so proceeds with particular advantage, that the device for height adjustment on the other supporting portion is provided, and in that the other support portion in the range this apparatus almost concentric at least to the pivot joint. This also makes it possible to adjust the height very simple, obvious and without forming a large number of moving parts, this in an aesthetically pleasing manner.

A particularly advantageous height adjustment is characterized in that the cooperating with the device for height adjustment support portion is provided in the manner of a toothed rack with a toothing which meshes with a rotatable gear by the user of the chair of the device. Thereby, the support portion is incorporated directly as an active part in. The device for height adjustment, whereby it so happens in a particularly advantageous manner that the toothing is incorporated directly into the material of the support portion.

A außerordentl ch advantageous development of the invention is characterized in that a manually operated driving device is provided for driving the gear, which has a detent in at least one predetermined rotational position. One need in this case to provide a separate locking device, but the device for height adjustment only needs to be of a detent position to the next twisted and is then secured against unintentional displacement. In this case, it is, preferably, so that the front wheel is provided on its drive eccentrically with a coupling member, which in turn is eccentrically connected to a second rotary member, and in that the coupling member associated with the manually actuatable drive device. The coupling member connects thereby the gear - completely analogous to the coupling between two drive wheels of a locomotive - with the second rotary member, so that they are positively coupled, wherein, if necessary, an additional coupling, such as can be provided even by a toothed belt, and the coupling member is in turn driven by the manually operable drive device when it is rotated by the user of the chair.

Further details and advantageous refinements of the invention will become apparent from the hereinafter described and illustrated in the drawing, in any way as limiting the invention to be understood embodiments, and from the remaining dependent claims. It shows:

Fig. U 15. 16 is an explanatory view of another, less preferred apparatus for height adjustment of the armrest.

Fig. 1 shows an office chair 10 with a base frame 11 with rollers 12 on which a seat portion 13 and a backrest 14 are fixed. Seat portion 13 and backrest 14 are shown only schematically, as an armrest 18. The armrest 18 can support has a Armauflageabschnitt 22, on which the user of the chair 10.seinen left forearm. (Naturally, it will provide for such an armrest 18 on both sides of the chair. 10)

From Armauflageabschnitt 22, a front support portion 17 extends downwardly, and that is rigidly secured to the underside of the front portion of the seat portion 13 at a location sixteenth The support portion 17 extends at an angle alpha of 60 °, for example, obliquely forwardly and upwardly to a hinge point 21 where it merges into the Armauflageabschnitt 22nd The latter extends in this embodiment from the pivot point 21 back and upward, and here, as shown, is curved convexly upwards. The angle at the joint portion 21 is, as illustrated, variable, for example, in this embodiment, about 100 to 110 °.

The Armauflageabschnitt 22 extends to a point 23 and passes there through into a rear support portion 24 extending approximately concentrically downwards and towards the joint 21 and is height-adjustably mounted in its lower portion at a device 26 for height adjustment, in turn, at the bottom is of the seat portion 13 and fixed at its rear region by means of a fastening part 30th The distance of the rear supporting portion 24 from the joint 21 is referred to in Fig. 1 with R.

As shown in FIG. 2 in an enlarged scale, the joint can be formed as a flexible portion 21 of the armrest 18. Alternatively, for example, a "hinge at this site may be provided which allows there rotation between the front support portion 17 and the Armauflageabschnitt 22 -. In this way, it becomes possible to Armauflageabschnitt 22 between the uppermost position shown in Figure 1 with solid lines. and to adjust the lowest position 22 shown in Fig. 1 by dash-dotted lines' continuously.

At the rear support portion 24, two stops 28, 29 are provided, of which the upper stopper 28 abuts against the attachment device 26 when the armrest 18 is in its lowermost position, as shown by the dash-dotted representation 28 ', and wherein the lower stop 29 against the mounting device 26 abuts when the armrest is in its uppermost position eighteenth (In the lowermost position shown in phantom this stop is denoted by 29 '.)

Fig. 3 shows another embodiment of a chair according to the invention 10 '. The basic structure of the chair largely corresponds to that according to Fig. 1, and therefore the same reference numerals are used as in Fig. 1 for identical or identically functioning parts, and those parts will not be described again. This similarly applies to the following further embodiments.

The height-adjustable arm rest 18 'is here with its front support portion 17' at a point 16 'pivoted to the underside of the front portion of the seat portion. 13 The armrest 18 'is formed continuously rigid in FIG. 3. Its front support portion 17 'is at a location 21' at an angle of about 110 ° in a Armauflageabschnitt 22 '' over, which can be constructed similar to the corresponding portion 22 of Fig. 1. At a point 23 'is the Armauflageabschnitt 22 '' at an angle of for example 110 ° about the downwardly extending rear support portion 24 ', which is formed straight in its upper region and down' 'passes, which is substantially concentric to the articulation point 16' in a curved portion 24 extends, and * it has the distance R. The curved portion 24 "is provided with an upper stop 28 'and with a lower stop 29" and is disposed on an apparatus 26' for height adjustment, which device, as shown, on the rear underside of the seat part 13 by means of a fixing part 30 is attached.

As understood from Fig. 3, the arm 18 can r between an upper end position, which is shown in Fig. 3 by solid lines, and a lower end position, which is shown in Fig. 3 with dash-dotted lines, be adjusted continuously. The stops 28 "and 29" limit this adjustment process downwards or upwards.

The arrangement of FIG. 4 shows a chair 10 "with a height-adjustable armrest 18", which is more or less a mirror image to the array of FIG. 3. This has an approximately horizontally extending Armauflageabschnitt 22 " 'having a rear support portion 24"' and a front supporting portion 17 ". It is designed to be continuous rigid.

The rear support portion 24 ' "is here pivoted to the underside of the rear portion of the seat portion 13 at a joint 35th At its upper end 23'" he goes at an angle of approximately 90 ° in the Armauflageabschnitt 22 " 'over, and this in turn passes at its front end 21 '' at an angle of about 110 ° in a straight portion 17 '' of the front housing section 17 "above. To the straight portion 17 '' ', a curved portion 17 includes downwardly ", which, as illustrated, is concentric to the articulation point 35 and by this the distance R' 'r. The curved portion 17" "is provided with an upper provided stop 28 '' and a lower stop 29 " 'and it is located on a device 26' 'for height adjustment, which device, as shown, attached to the front underside of the seat part 13 by means of a fastening part 36th

As shown in Fig. 4 clearly shows, the armrest 18 may be '29 and "limit" between an upper end position, shown in solid lines, and a lower end position, which is shown with dash-dotted lines, be adjusted continuously. The stops 28 "' this displacement in the manner shown by upward and downward.

Fig. 5 shows a chair 10 " 'analogous to the preceding figures 18a with a height-adjustable armrest. This has is an approximately horizontally extending Armauflageabschnitt 22a and a front support portion 17a, the latter is arranged on a device 26a for adjusting the height. Latter by means of a fastening member 37 attached to the underside of the forward portion of the seat part. 13

The support portion 17a can here be straight in the illustrated manner, and for example at an angle beta of about 70 ° to 80 ° to the horizontal (line 38) extend forward. Its uppermost position shown in Fig. 5 in solid lines, and is limited by a lower stop 29a. Its lowermost position shown in Fig. 5 with dash-dotted lines and is limited by an upper stop 28a. Here there is the advantage that the Armauflageabschnitt yields 22a somewhat resilient under stress, which is perceived by the user as pleasant and can be used to isometric exercises.

The arrangement of FIG. 6 is essentially the mirror image of the arrangement of FIG. 5. The seat shown therein 10 "" has a height-adjustable armrest 18b with an approximately horizontally extending Armauflageabschnitt 22b and a path extending from the rear end thereof downward rear support portion 24b that is straight and disposed at a device 26b for the height adjustment. The latter is secured to the underside of the rear portion of the seat part 13 by means of a fastening member 38th

The rear support portion may extend obliquely downwardly 24b here in the manner shown. Its uppermost position shown in Fig. 6 with solid lines, and is limited by a lower stopper 29b. Its lower position shown in Figure 6 in dash-dot lines and is limited by an upper stop 28b. - Also in this embodiment of Armauflageabschnitt 22b can yield somewhat resilient under stress. The variants according to FIGS. 5 and 6 are particularly advantageous in conjunction with the apparatus for adjusting the height as shown in FIGS. 9 to 14.

FIGS. 7 and 8 show a first device for adjusting the height H, as they can be used in all the embodiments described above.

A support portion S of the armrest 18 (or 18 ', 18 ", 18a, 18b) is formed here in regions in the manner of a toothed rack 50, the teeth 51 are incorporated directly into this part of the support portion S.

These teeth 51 is a gear 52 which is connected via a shaft 53 to an actuator 40, which preferably has the shape of a hand wheel meshes. turning, based on Fig. 8, this hand wheel and thus the gear 52 in the clockwise direction, ie in the direction of the arrow 54, the support portion S is moved in the direction of arrow 55 downward. With counterclockwise rotation, the support portion S is moved upward. In this way, a very simple adjustment is possible. The handwheel 40 can be formed so that it is rotatable only when, for example, has been shifted slightly in the axial direction before, against the action of a spring (not shown). Such locks are known per se and therefore not shown in the drawing. Also, the storage of the handwheel is not shown 40th

The device H for height adjustment of FIGS. 7 and 8 can be used in Fig. 1 for the local device 26 in Fig. 3 for the apparatus 26 'in Fig. 4 for the device 26 "' in Fig. 5 for the device 26a and in Fig. 6 for the apparatus 26b. for the skilled reader that is self-evident.

A second preferred apparatus 60 for height adjustment is shown in Figs. 9 to 14. Again, a longitudinal tooth 61 is in the supporting member S incorporated, and this meshes with a gear 62 which is mounted in a housing 63, in which the support member S is longitudinally displaceably guided and supported.

The gear 62 is connected via its shaft 64 having a first rotatable portion 66, that is, when the first rotatable member 66 rotates, the gear 62 rotates in the same way. Axis of rotation of the gear 62 and rotating part 66 is designated by the 67th

The part 66 is located inside of a hand wheel 68 which is mounted on a central shaft 70 in a recess 72 of the right wall 73 of the housing 63 and is secured there by a snap ring 75 miles.

In a recess in the interior of the hand wheel 68, a second rotatable member 76 is arranged, the axis of rotation 77 extends parallel to the axis of rotation 67th The rotatable members 66 and 76 are preferably, as illustrated, in the same plane.

At a distance R from the rotation axis 67 on the first rotatable member 66, a eccentric pin 80 is disposed and stored in a corresponding recess 81 of a coupling member 82nd

Also, an eccentric pin 85 is provided on the second rotatable member 76 and stored in a corresponding recess 86 of the coupling member 82 at a distance r from the rotation axis 77th

Fig. 13 shows the coupling member 82 in the form of a hexagonal portion. This hexagonal shape has nothing to do with the function of the part, but this part has only the function as well as the coupling rod between two drive wheels of a locomotive force a synchronous rotation of the parts 66 and 76th This can be possibly still .Supports by a toothed belt 88 (Fig. 12) 66 and 76 also couple the parts together. (When the wheels of a locomotive, this additional coupling is effected by the rail on which run the wheels.)

As 14a to 14f show the Fig., The coupling member 82 may take various translational positions upon actuation, wherein 62 and thus causes a corresponding rotation of the gear height adjustment of the support member S.

Whereby the translational movement of the coupling member 82 will now be effected? The coupling member 82 has in its central inner region a circular recess 90, and this is to contact the central shaft 70 in any possible position in translation of selected so large. On the shaft 70 a radially projecting arm 92 is fixed and located at the free end of a latching member 94, here in the form of a roller, which is pressed by a spring 95 radially outward.

This detent member 94 is located against the inner periphery of the recess 90, and if - by turning the hand wheel 68 - the arm 92 is rotated, it causes a corresponding translational movement of the coupling member 82 and thus a rotation of the gear 62nd

The recess 90 has on its circumference at least one latching recess. In the exemplary embodiment the two recesses 97 and 98 which are diametrically opposite to each other. The locking member 94 is located in Fig. 13 in the locking recess 97 and engaged characterized in this position, the coupling member 82 and thus the gear 62, so that the height of the support member S even can not change when it is charged, for example, because someone is sitting on the arm. Further possible latching recesses on the circumference of the recess 90 are indicated by dashed lines and designated in FIG. 13, with 101 and 102. These locking positions are less favorable.

To explain the mode of action, reference is made to Figure 14..

FIG. 14a is reduced representation of FIG. 13, the details are omitted. In Fig. 14b, the arm 92 is compared with FIG. 14a by about 90 ° rotated in the counterclockwise direction, and thereby also the two eccentric pins 80 and 85 are rotated by 90 ° counterclockwise, and thus the gear 62, so that the support member S is moved upward.

In Figure 14c., The arm 92 has rotated with respect to Fig. 14a by 180 ° and has brought about a rotation of the gear 62 by 180 °. In this case, the locking member 94 is locked in the latching recess 98th

Fig. 14d is identical to Fig. 14c.

In Fig. 14e, the arm 92 has with respect to FIG. 14d rotated through a further 90 degrees and has thereby causing a further rotation of the gear 62 by 90 °. And Fig. 14f a full rotation of the arm 92 a full rotation of the gear is completed, as well 62. In the two locking positions according to Fig. 14a / f or Fig. 14c / d coupling member 82 and arm 92 are locked together, thereby blocking the height adjustment of the support member S. particularly in Fig. 14c / is immediately intuitively apparent d in that a rotation of the first rotatable portion 66 is blocked, because it is a so-called dead center position. This applies equally for reasons of symmetry, Fig. 14a / f, that is, in both rotational positions and a strong load on the respective arm rest can not cause undesired height adjustment. In contrast, an intentional height adjustment of these two detent positions is quite possible, since this requires only little latching force has to be overcome.

Thereby, the height adjustment is very simple and obvious, so the user only rotates the handwheel 68, and even if it does not rotate this up into a locking position, can turn the part 66 if necessary so far under load of the respective arm rest, until the arm 92 in one of its stop positions is reached, corresponding to the dead center positions in a preferred manner in the embodiment. This also contributes to workplace safety.

A third variant of a device for adjusting the height shown in FIGS. 15 and 16, wherein the support member S is shown in the form of a tube here.

Below the seat 13, a tube 132 is provided here to which a provided with an externally threaded pin 133 is fixed 134 which forms a shoulder 135 at its transition to the pipe 132nd Against this shoulder 135 is located a metal disk 136, and this supports a plastic part 137 from which, as shown, provided with a recess 138 for the supporting member S.

subsequent to the plastic part 137 is a plastic part 141, which is also provided in the illustrated manner with a recess 142 for the supporting member S, and the plastic part 141 followed by a second metal disc 143rd

Onto the external thread 133 outside a knurled nut 145 is screwed from plastic, which has the form of a handwheel and can be easily operated by hand. As can be seen readily, is clamped by tightening the nut 145, the supporting member S between the plastic parts 137 and 141 and thereby fixed with regard to its altitude. For height adjustment, the nut is loosened 145, the support member S is moved to the desired position, and then the nut 145 tightened again.

In the invention, it is possible to the disc 136 and the part 137 rigidly, or with a slight play to connect with the tube 132, as the supporting member S is concentric to the pivot 121 and does not change its direction upon adjustment.

Thus, the invention allows an individual adjustment to the user's needs. The adjustment is simple and obvious, and it can be done by the user when sitting on the chair, which enables an optimal and also very ergonomically ical adjustment.

Naturally, many variations and modifications are possible within the scope of the invention. Thus, the type of adjustment according to FIGS. Can be 9 to 14 applied for other purposes, ie it also has independent significance. On the arc-shaped arm part can be attached that represents the actual armrest, eg a padded part, a plastic molding, or the like, as is often the case in practice, and the shape of this arm rest can of course also on the form the armrest vary and survive example of this. These and similar modifications are within the scope of the present invention.
