Anordning rid stolar med h5j- och sankbar sits. Device rides chairs with h5j and submersible seat.

Uppfinuare: C. E. E. Lundquist. Inventor: C. E. E. Lundquist.

Foreliggande uppfinning hanfor sig till en anordning yid stolar med hoj- och sankbar sits for fastlasning ay den sitsen uppbarande stolpen relativt stolens stativ, omfattande en i stativet vridbart anbragt klamring, som under paverkan fran en fjaderkraft intager ett snett lage kring stolpen och under klamverkan fasthaller derma mid stativet. Uppfinningen avser att astadkomma en anordning av denna art, som forenar enkelhet i utformning med god stabilitet och som är bekvanat manOvrerbar. Detta ernas vasentligen darigenom att ett med klamringen fast forbundet hand-tag är medelst en avlang slits underifran lost patradd ett nedatskjutande utsprang fran sta.- tivet, kring vilket utsprang handtaget och klamringen aro svangbart lagrade samtidigt som de hava en miss rorelsefrihet i riktning till och Iran stolpen, varjamte en fjader anliggcr vid sin ena anCe mot en avsats pa utspranget under handtaget och av denna avsats halles i lage under det att fjaderns andra ande trycker handtaget uppat Uppfinningen skall nedan narmare beskrivas under hanvisning till 0 bifogade ritning som exempel visade utforingsformer, varvid aven ytterligare uppfinningen kannetecknande egenskaper skola angivas. The present invention relates to a device for chairs with a height-adjustable seat for attachment to the post supporting the seat relative to the stand of the chair, comprising a clamping ring rotatably arranged in the frame, which under the influence of a spring force assumes an oblique bearing around the post and holds derma mid stand. The invention aims to provide a device of this kind, which combines simplicity in design with good stability and which is conveniently manoeuvrable. This is essentially due to the fact that a handle fixedly attached to the clamping ring is by means of an elongate slot loosely patterned below a projecting projection from the frame, around which the handle and clamping ring protrude are pivotally mounted at the same time as they have a freedom of movement in the direction of and The Iran pillar, in which a spring abuts at its one end against a ledge on the projection under the handle and of this ledge is held in position while the other spirit of the spring pushes the handle upwards The invention will be described in more detail below with reference to the accompanying drawings, by way of example, in which further embodiments of the invention may be indicated.

I fig. 1 visas ett parti av en stol med en fastlasningsanordning enligt uppfinningen clelvis j vertikalsektion. Fig. 1 shows a portion of a chair with a welding device according to the invention in a vertical section.

I fig. 2 visas en sektion efter linjen i fig. 1. Fig. 2 shows a section along the line in Fig. 1.

I fig. 3 slutligen visas en nagot modifierad utfOringsform av uppfinningen i en sektion motsvarande den enligt fig. 2. Finally, Fig. 3 shows a somewhat modified embodiment of the invention in a section corresponding to that of Fig. 2.

A ritningen betecknar 10 en stolpe eller spindel i form av ett ror, vilken uppbar en stolsits (ieke visad). Spindeln 10 Or anordnad axiellt g,lidbar i en hylsa 12, som tillika med ben 14 utgOr det mot ett underlag vilande stolstativet. A stativet, lampligen 0 hylsan 12, sasom mid dess nedre del, är fast ett utsprang 16, d vilken lasanordningen enligt uppfinningen, bestaende av en omkring spindeln 10 anbragt ring 18 och ett med denna forbundet handing 20, Or lagracl. Utspranget 16, som har foretradesvis aylang tvarsektion i horisontalplanet, är for detta andamal forsett med en inskarning 22 pa ena sidan och en avsats 24 pa den andra sidan, som inga i ett avlangt hal 26 i handtaget 20. Det avlanga halet 26 Or av storre langd an avstandet mellan inskarningens 22 botten och avsatsen 24, for att samtidigt med att ringen 18 och handtaget 20 Oro svangbara i vertikalled (i plan genom spindelns langdaxel) kring utspranget 16, en miss rarelsefrihet skall forefinnas mellan ring-en on handtaget a ena och utspranget 16 0 andra sidan i riktning mot och frail spindeln. Utspranget 16 har nedanfor inskarningen 22 och avsatsen 24 storre bredd och bildar en ansats 28 for kvarhallande av en bladfjader 30, vilken under initialspanning anligger mot handtaget 20 invid deltas fria ande. Pa motsatt sida om anslaget 28 har utspranget 16 en inskarning 32 for bladfjadern. Fjadern 30 astadkommer, att ringen 18 installer sig snett relativt spindeln 10, d. v. s. under en relativt liten vinkel mot horisontalplanet. Saval handtaget 20 som fjadern 30 Oro lost tradda pa utspranget 16, d. v. s. sakna sarskilda fastsattningsorgan. In the drawing, 10 denotes a post or spider in the form of a rudder, which carried a chair seat (not shown). The spindle 10 is arranged axially and slidably in a sleeve 12, which together with the legs 14 forms the chair frame resting against a base. Attached to the frame, i.e. the sleeve 12, as well as to its lower part, is a projection 16, in which the welding device according to the invention, consisting of a ring 18 arranged around the spindle 10 and a handle 20, Or bearing clamp connected thereto. The protrusion 16, which preferably has a long transverse section in the horizontal plane, is for this purpose provided with a notch 22 on one side and a ledge 24 on the other side, which are not in an elongated hole 26 in the handle 20. The elongated tail 26 Or of greater length than the distance between the bottom of the notch 22 and the ledge 24, so that at the same time as the ring 18 and the handle 20 are pivotable in the vertical direction (in plane through the longitudinal axis of the spindle) about the projection 16, a freedom of movement must be present between the ring on the handle one and the projection 16 side in the direction of and frail the spider. The projection 16 has a larger width below the notch 22 and the ledge 24 and forms a shoulder 28 for retaining a leaf spring 30, which during initial tension abuts against the handle 20 next to the free spirit of the delta. On the opposite side of the stop 28, the projection 16 has a notch 32 for the leaf spring. The spring 30 causes the ring 18 to settle obliquely relative to the spindle 10, i.e. at a relatively small angle to the horizontal plane. Saval handle 20 as the spring 30 Oro lost threaded on the projection 16, i.e. lacking special fastening means.

Ringen 18 Or sO uthildad, att den anligger mot spindeln 10 0 minst tre stallen. Vid utf5- ringsformen enligt fig. 1 och 2 har ringen 18 pa insidan utf ormats med tva i vinkel mot varandra staende vtor 34, vilka darvid ligga pa mar sin sida om en linje genom spindelns centrum och utsprangets 16 mitt. Ytorna 30 Oro vidare forlagda ph motsatt sida om spindeln 10 mot handtaget 20. DO lasanordningen befinner sig i sparrlaget angivet med heldragna linjer i fig. 1 och 2, framkalla ytorna 30 en kilverkan, som sfikerstaller den ovan namnda effekten, nfimligen att spindelns axiallage fixeras samtidigt med att en vridningsrorelse Indian spindeln 10 och stativet med sakerhet forhindras, Oven da spindeln uppbar belastning. Det har visat sig att laseffekten blir sarskilt framtradande, da spindeln 10 Or rorformig, och sarskilt goda resultat hava erhallits med rorspindlar, utfOrda av fjadrande material, sasom stal. 2— — Genom att fora handtaget 20 nedat enligt fig. 1 kring utspranget 16 ror sig ringen 18 uppat till ett lage, dar den atminstone tillnarmelsevis ligger i plan vinkelratt mot spindelaxeln, sasom angivits med prickstreckade linjer i figurerna. Ringens 18 sparringrepp med spindeln 10 har darmed upphort och denna kan forskjutas i sin langdriktning. Anordningen r fOretradesvis sa utford, att utspranget 16 hindrar handtaget frail att svanga langre ned an till delta lage. Vid den visade utioringsformen kommer handtaget 20 resp. ringen 18 i det ifragavarande laget i kontakt med avsatsen. 24. Handtaget 20 kan alltsd joke svh.ngas neat sa langt att ringen 18 instiller sig i motsvarande byre klamlage. The ring 18 Or sO uthildad, that it abuts against the spindle 10 0 at least three stables. In the embodiment according to Figs. 1 and 2, the ring 18 on the inside has been formed with two surfaces 34 at an angle to each other, which thereby lie on their side about a line through the center of the spindle and the center of the projection 16. The surfaces 30 are further located opposite the spindle 10 towards the handle 20. The welding device is located in the ratchet layer indicated by solid lines in Figs. 1 and 2, the surfaces 30 produce a wedge action which ensures the above-mentioned effect, namely that the axial layer of the spindle is fixed at the same time as a rotational movement of the Indian spindle 10 and the frame with safety is prevented, even when the spindle carried load. It has been found that the laser effect becomes particularly prominent, since the spindle 10 is rudder-shaped, and particularly good results have been obtained with rudder spindles, made of resilient material, such as steel. 2— - By sliding the handle 20 downwards according to Fig. 1 around the projection 16, the ring 18 moves upwards to a bearing, where it lies at least approximately in a plane perpendicular to the spindle axis, as indicated by dotted lines in the figures. The sparring engagement of the ring 18 with the spindle 10 has thus ceased and this can be displaced in its longitudinal direction. The device is preferably so challenged that the projection 16 prevents the handle from swinging further down than to the delta layer. In the embodiment shown, the handle 20 resp. ring 18 in the team in question in contact with the ledge. 24. The handle 20 can thus be jogged neatly so far that the ring 18 adjusts to the corresponding clamping position.

Medan vid utforingsformen enligt fig. 2 ringen 18 är av krokt form resp. cirkelform vid kontaktytan mot spindeln 10 pa motsatt sida om ytorna 34, liar utforingsformen enligt fig. 3 tvapunktsanliggning aven vid denna sida. Ringen 18 är salunda utformad med ytor 36, som sta. symemtriskt 1 fOrhallande till den ovannamnda linjen genom utsprangets 16 mitt och spindelns centrum. Lhsanordningen enligt fig. 3 kan i ovrigt vara utford pa sa:mma satt enligt den foregaende utforingsformen, varfor samma beteckningar anvants for motsvarande delar. While in the embodiment according to Fig. 2 the ring 18 is of crooked shape resp. circular shape at the contact surface against the spindle 10 on the opposite side of the surfaces 34, the embodiment according to Fig. 3 also has a two-point abutment also at this side. The ring 18 is thus formed with surfaces 36, which stand. symmetrically 1 relative to the above-mentioned line through the center of the projection 16 and the center of the spindle. The reading device according to Fig. 3 can otherwise be challenged in the same way according to the preceding embodiment, for which reason the same designations are used for corresponding parts.

Uppfinningen ar givetvis icke begransad till de visade utforingsformerna utan kan varieras i manga avseenden inom ramen for de efterfoljande patentanspraken. The invention is of course not limited to the embodiments shown but can be varied in many respects within the scope of the appended patent claims.
