Description

469 366 vilken rören kvarhàlls av en làssprint 7. De båda rören lig- ger i samma plan vilket gjorts möjligt genom att ett mitt- parti av röret 5 avlägsnats och ersatts med två plattjärn 6 som fastsvetsats på rörets över- respektive undersida. Genom att det avlägsnade rörstycket är något längre än rörens 4 ¿ och 5 ytterdiametrar kan vinkeln mellan rören varieras från ca 60° till ca 120” vilket är nödvändigt för att anordningen enligt uppfinningen skall kunna anpassas till olika fåtöljer. 469 366 which the pipes are held by a locking pin 7. The two pipes lie in the same plan, which has been made possible by a portion of the tube 5 has been removed and replaced with two flat irons 6 which is welded to the top and bottom of the pipe, respectively. Through that the removed pipe section is slightly longer than the pipes 4 ¿ and 5 outer diameters, the angle between the tubes can be varied from about 60 ° to about 120 ”which is necessary for the device according to the invention it must be possible to adapt to different armchairs.

Runt rörens ytterändar är fyra rullorgan, såsom kul- lager 8, fastsatta på sådant sätt att de rullar mot plattan 1 när de korslagda rören vrids kring axeln. För att anord- ningen skall kunna anpassas till olika fåtöljer krävs inte bara att vinkeln mellan rören kan varieras utan också att rören kan förlängas. Detta har gjorts möjligt genom teleskop- rör 9 som kan förskjutas i rören. Teleskoprören är i sina ytterändar försedda med fastsvetsade bärorgan i form av vin- keljärn 11 som genom hål 12 kan fästas i undersidan av få- töljens ben, vilka därmed fixeras på en nivå någon centi- meter ovanför golvet, varpå plattan 1 vilar. När detta är gjort dras stoppskruvar 10 fast, varigenom teleskoprören låses och fåtöljens ben ges samverkande stabilitet.Around the outer ends of the tubes are four rolling means, such as bearings 8, fixed in such a way that they roll against the plate 1 when the crossed tubes are rotated about the axis. In order to it must be possible to adapt to different armchairs is not required only that the angle between the tubes can be varied without also that the pipes can be extended. This has been made possible by telescopic tube 9 which can be displaced in the tubes. The telescopic tubes are in theirs outer ends provided with welded support members in the form of winches iron 11 which can be fastened through holes 12 in the underside of the the legs of the chair, which are thus fixed at a level some centi- meters above the floor, on which the plate 1 rests. When this is done, stop screws 10 are tightened, whereby the telescopic tubes locked and the legs of the armchair are given cooperative stability.

I ett alternativt i fig. 3 visat utförande kan plattan 1 ersättas av en ring 13 och ekrar 14, som i sina radiellt inre ändar upptar axeln 3.In an alternative embodiment shown in Fig. 3, the plate can 1 is replaced by a ring 13 and spokes 14, which in their radial inner ends occupy the shaft 3.
