Abstract

The invention relates to a device in a chair (1) having an arm rest (2) supported by at least one support rod (3, 4) at the support frame (5) of said chair (1), the arm rest (2) being lockable in different vertical positions by means of a lock sleeve (6) keeping said support rod in position, the free, or lowermost, section (10) of the support rod (3, 4) exhibiting a stop member (9) which is displaceable along and lockable to said support rod (3, 4), so as to limit the upwards directed travelling distance of said arm rest (2) and to define a predetermined vertical and/or original position of the arm rest (2) which the latter can conveniently resume after having been set in other, temporary adjustment positions.

Description

520 357 .ß LU- visar i en förstorad skala ett stopporgan i tvär- 1 för fig. 2 sektion, som används vid bärstängerna i fig. åstadkommande av repeterbar inställning av arm- stödshöjden. 520 357 .ß LU- shows on an enlarged scale a stop means in cross section 1 of Fig. 2, which is used with the support rods in Fig. To provide a repeatable adjustment of the armrest height.

Såsom närmare framgår av fig. 1, visas här schematiskt en stol 1 med ett armstöd 2, som uppbärs av två bärstänger 3, 4. Dessa bärstänger 3, 4 uppbärs i sin tur av vid stolens bärram 5 fast anordnade låshylsor 6, i vilka bärstängerna 3, 4 är vridbara i och för armstödets 2 inställning i önskade lägen. Låsningen av bärstängerna 3, 4 vid bärramen sker med hjälp av en rattförsedd låsskruv 7, som är medelst en gängformation 8 in- och utskruvbar genom hylsans 6 mantelyta i och för lägesfixering av åtminstone den ena bärstången 3, 4.As can be seen in more detail from Fig. 1, a chair 1 is schematically shown here with an armrest 2, which is supported by two support rods 3, 4. These support rods 3, 4 are in turn supported by locking sleeves 6 arranged at the support frame 5 of the chair, in which the support rods 3, 4 are rotatable due to the setting of the armrest 2 in the desired positions. The locking of the support rods 3, 4 at the support frame takes place by means of a knurled locking screw 7, which can be screwed in and out by means of a thread formation 8 through the casing surface of the sleeve 6 for position fixation of at least one support rod 3, 4.

Vid den visade utföringsformen uppvisar de bägge bärstäng- erna 3, 4 var sitt stopporgan 9 i det fria eller nedersta partiet 10 av bärstängerna 3, 4. Stopporganen 9 är för- skjutbara kring och låsbara vid bärstängerna 3, 4 och är vidare avsedda att samverka med hylsornas 6 underkanter i och för begränsning av armstödets 2 rörelsesträcka uppåt, varvid man härigenom åstadkommer ett förinställt höjdläge och/eller utgångsläge för armstödet 2, vilket detta lätt kan inta efter inställning till andra, tillfälliga inställ- ningshöjder.In the embodiment shown, the two support rods 3, 4 each have their own stop member 9 in the free or lower part 10 of the support rods 3, 4. The stop means 9 are displaceable around and lockable at the support rods 3, 4 and are further intended to cooperate. with the lower edges of the sleeves 6 in order to limit the upward distance of movement of the armrest 2, whereby a preset height position and / or initial position of the armrest 2 is thereby achieved, which this can easily assume after adjustment to other, temporary adjustment heights.

Såsom närmare framgår av fig. 2, visas här det stopporgan 9 som används på bärstängerna 3, 4 i och för åstadkommande av den repeterbara inställningen av armstödshöjden och vilket stopporgan 9 utgörs av en bärstängerna 3 omslutande hylsa 11, genom vars mantelyta 12 sträcker sig en rattförsedd låsskruv 13 i och för lägesfixeringen av denna vid bär- stängerna 3, 4. u. ..As can be seen in more detail from Fig. 2, the stop means 9 used on the support rods 3, 4 is shown here in order to achieve the repeatable adjustment of the armrest height and which stop means 9 consists of a sleeve 11 enclosing the support rods 3, through which a circumferential surface 12 extends. steering wheel-mounted locking screw 13 for the position fixation of this at the support rods 3, 4. u. ..

Claims

520 ssvšf 3 Patent claims Device for an armrest (2) included in a chair (1), which is supported by at least one support rod (3; 4) at the support frame (5) of the chair (1) and at which support frame (5) the armrest (2 ) is lockable in different height positions by means of a support rod (3; 4) position-fixing locking sleeve (6), characterized in that the free or lower part (10) of the support rod (3; 4) has a stop member (9) which is slidable along and lockable at the support bar (3; 4) for limiting the upward movement of the armrest (2) and which forms a preset height position and / or initial position for the armrest (2), which it can easily assume after adjustment to other, temporary adjustment heights , and which stop means (9) consists of a sleeve (11) enclosing the support rod (3; 4), through whose jacket surface (12) extends a steering wheel-provided locking screw (13) for positioning the sleeve (11) at the support rod (3; 4).
