Description
vaosses-2 W Dessa och övriga för uppfinningen utmärkande detaljer och fördelar förklaras närmare med hänvisning till bifogade ritningar, som visar en utföringsform av manöveranordningen enligt uppfinnin- gen, med en gasfjäder som fjäderanordning. vaosses-2 W These and other details and features of the invention advantages are explained in more detail with reference to the accompanying drawings, showing an embodiment of the operating device according to the invention gene, with a gas spring as the spring device.
Fig. 1 är en schematisk perspektivbild av en stol med manöver- ringen anordnad under benstativet för att möjliggöra fotmanövrering och fig. 2 är ett snitt genom manöverringens lagring i fig. l vid stolens nedre ände.Fig. 1 is a schematic perspective view of a chair with operating the ring arranged under the leg frame to enable foot maneuvering and Fig. 2 is a section through the bearing of the control ring in Fig. 1 at the lower end of the chair.
Stolen har ett benstativ 10, som via en stolpe i form av en gasfjäder 12 uppbär en rund sits 14. Om så önskas kan stolen vara försedd med ett ryggstöd 16 såsom antydes schematiskt med punkt- streckade linjer.The chair has a leg frame 10, which via a post in the form of a gas spring 12 carries a round seat 14. If desired, the chair can be provided with a backrest 16 as schematically indicated by dashed lines.
Gasfjädern är av det konventionella utförande som består av en cylinder 18 med en däri förskjutbar kolv (ej visad), som uppbär en ventil och är fäst vid en kolvstång 20. Ventilen är påverkbar medelst en tryckpinne 22 som sträcker sig ut med en fri längd utan- för kolvstångens ände. Intryckning av tryckpinnen medför att venti- len öppnar för den inuti cylindern komprimerade gasen, som därvid trycker mot kolven för utskjutning av kolvstången till en större längd. Alternativt är det möjligt att mot verkan av den komprimera- de gasen trycka in kolvstângen till ett önskat läge, innan tryckpin- nen släppes och gasfjädern låses i det nya läget.The gas spring is of the conventional design consisting of a cylinder 18 with a piston (not shown) displaceable therein, which carries a valve and is attached to a piston rod 20. The valve is actuatable by means of a pressure pin 22 extending with a free length outside for the end of the piston rod. Pushing in the push pin means that the len opens for the gas compressed inside the cylinder, which thereby presses against the piston to extend the piston rod to a larger one length. Alternatively, it is possible that against the action of the compressor the gases push the piston rod to a desired position, before the pressure pin is released and the gas spring is locked in the new position.
Manöverringen 26 i fig. l ligger koaxiellt nedanför kolvstån- gen 20 och uppbäres av ett antal radiella armar 48 i ett läge nedan- för benstativets ben så att ringen bekvämt kan nås med ena eller andra foten.The operating ring 26 in Fig. 1 lies coaxially below the piston 20 and is supported by a number of radial arms 48 in a position below for the legs of the leg stand so that the ring can be conveniently reached with one or other foot.
Manöverringen 26 är uppburen av ett antal radiella armar 48, vilka vid sina inre ändar är fästade vid en cirkulär tryckplatta 50, vilken ligger inuti ett hylsformat hus 52, vid vilket benstati- vet 10 är fäst.The operating ring 26 is supported by a number of radial arms 48, which at their inner ends are attached to a circular pressure plate 50, which is located inside a sleeve-shaped housing 52, at which the bone know 10 is attached.
Plattan 50 ligger vid husets nedre ände och hålles medelst en fjäder 54 till anliggning med sitt kantparti mot en ringformad stödyta i form av en ring 56, som anligger mot en i huset fäst lås- ring 58.The plate 50 is located at the lower end of the housing and is held by a spring 54 for abutment with its edge portion against an annular support surface in the form of a ring 56, which abuts against a locking ring 58.
I huset är fäst en mothållsplatta 60, som bildar stöd för fjä- dern 54 och som har en central öppning för en fritt rörlig plunge 62.Attached to the housing is a retaining plate 60, which forms a support for the spring. 54 and having a central opening for a freely movable plunge 62.
På plattan 60 är fäst ett rör 64, som vidgar sig upptill för mottagande av kolvstângens 20 ände, varvid hylsan är slitsad och för- sedd med öron 66 för fastklämning på kolvstången.Attached to the plate 60 is a tube 64, which widens at the top receiving the end of the piston rod 20, the sleeve being slotted and seen with ears 66 for clamping on the piston rod.
J 7803586 - 2 När ringen 26 tryckes ned vid vilken som helst punkt utmed sin omkrets till anliggning mot golvet, vilken nedtryckning är av- sedd att ske med foten, kommer tryckplattan 50 att vippas kring en punkt utmed sin omkrets med stöd mot ringen 56, varvid plattans 50 centrala parti förflyttas i riktning mot pinnen 22 och trycker in denna genom förmedling av plungen 62, så att gasfjädern frikopplas.J 7803586 - 2 When the ring 26 is depressed at any point along its circumference to abutment against the floor, which depression is seen to happen with the foot, the pressure plate 50 will be tilted around one point along its circumference with support against the ring 56, the plate 50 central portion moves in the direction of the pin 22 and pushes in this by means of the plunger 62, so that the gas spring is disengaged.
