Description

Izum se odnosi na okov namještaja za sjedenje, promljenljivog u krevet, pomoću kojega se kod smještaja u parovima okvir sjedala i okvir naslona mogu zakretno povezati s kosturom namještaja, te mogu biti u različitim položajima podesivi jedan spram drugoga, pri čemu su kostur namještaja i okvir naslona međusobno povezani preko dvije, međusobno povezane vodilice, te je na okviru sjedala okretljivo pričvršćena dvokraka poluga s više uskočnih stepenica, čija točka okretanja leži na spoju, koji se sastoji od dviju vodilica, između okvira naslona i okvira sjedala, te je sa svoje strane, koja je okrenuta suprotno od okvira sjedala, povezana preko vodilica s okvirom naslona. The invention relates to fittings for seating furniture, convertible into a bed, by means of which, when placed in pairs, the seat frame and the backrest frame can be pivotally connected to the furniture skeleton, and can be adjusted in different positions relative to each other, whereby the furniture skeleton and the frame backrests are connected to each other via two interconnected guides, and a two-armed lever with several snap-in steps is rotatably attached to the seat frame, the pivot point of which lies at the junction, which consists of two guides, between the backrest frame and the seat frame, and is on its side , which faces the opposite side of the seat frame, connected via guides to the backrest frame.

Kod poznatog okova ove vrste višestruka uskočna stepenica je izvedena kao dvojako uskočna stepenica, te se jedna od vodilica koja tvori vezu između naslona i okvira sjedala uz mogućnost razdvajanja odupire u stalnom ležištu. Nedostatak tog poznatog okova je u tome, da je srazmjerno teško izvesti oslanjanje međuvodilice u stalnom ležištu, nadasve radi tolerancija kojih se treba pridržavati, odnosno kod manje točnosti nije više moguće besprijekorno oslanjanje. Najviše radi toga je kod poznatog okova i predviđen jedan međupoložaj naslona između stvarnog položaja za sjedenje i ležanje. Različite osobe često daju prednost svaki puta drugačijem položaju za odmaranje, i zato sa samo jednim međupoložajem nije moguće zadovoljiti sve potrebe. With a known fitting of this type, the multiple step-in step is designed as a double step-in step, and one of the guides that forms the connection between the backrest and the seat frame, with the possibility of separation, rests in a permanent bearing. The disadvantage of this well-known fitting is that it is relatively difficult to support the intermediate guide in a permanent bearing, mainly because of the tolerances that must be observed, that is, with less accuracy, perfect support is no longer possible. The main reason for this is that with the well-known fittings, an intermediate position of the backrest between the actual sitting and lying position is provided. Different people often prefer a different resting position each time, and therefore it is not possible to satisfy all needs with only one intermediate position.

Zadaća izuma je stvoriti okov navedene vrste, kod kojega se postiže više međupoložaja naslona i pouzdano oslanjanje uz jednostavnu izradbu. To je izumom omogućeno time, da dvokraka poluga ima barem tri uskočne stepenice i da se uskočnim stepenicama suprotno ležeća strana dvokrake poluge naslanja na oslonac, koji je smješten na onoj vodilici između kostura namještaja i okvira naslona koja je od okvira sjedala udaljenija nego druga vodilica. Kod okova prema izumu, dvokraka poluga ima s jedne strane više od dvije uskočne stepenice, tako da je moguće više međupoložaja, dok se s druge strane ova poluga oslanja neposredno na svojoj strani, koja leži nasuprot uskočnim stepenicama. Oslanjanje je radi toga sigurnije i ravnomjernije nego posredno preko spoja koji se sastoji od dviju vodilica. The task of the invention is to create a fitting of the mentioned type, which achieves more intermediate positions of the backrest and reliable support with simple production. This is made possible by the invention by the fact that the two-armed lever has at least three steps and that the opposite side of the two-armed lever rests on the support, which is located on the guide between the frame of the furniture and the backrest frame, which is farther from the seat frame than the other guide. In the fittings according to the invention, the two-armed lever has on one side more than two snap-in steps, so that more intermediate positions are possible, while on the other hand this lever rests directly on its side, which lies opposite the snap-in steps. Therefore, the support is safer and more even than indirectly via a connection consisting of two guides.

U daljnjem tekstu je izum opisan podrobnije na temelju izvedbenog primjera, koji je predstavljen na slikama, ali se time ne ograničava izvedba samo na ovaj primjer. Kod toga prikazuju: In the following text, the invention is described in more detail on the basis of an embodiment, which is presented in the figures, but the embodiment is not limited to this example only. Here they show:

sl. 1 okov prema izumu u ležećem položaju, Fig. 1 shackle according to the invention in a lying position,

sl. 2 isti okov u stvarno sjedećem položaju, Fig. 2 the same shackle in the actual sitting position,

sl. 3 okov u jednom između dva međupoložaja, Fig. 3 the fitting in one of the two intermediate positions,

sl. 4 okov u drugom međupoložaju, pri čemu su okovom povezani okviri na crtežima svaki puta samo naznačeni. Fig. 4 the fitting in the second intermediate position, where the frames connected by the fitting are only indicated in the drawings each time.

Na kosturu 1 namještaja, s obje strane je pričvršćena po jedna pričvrsna ploča 2. Na svakoj pričvrsnoj ploči 2 su dvije vodilice 3 i 4 zakretljivo uležištene, čiji je kraj, koji leži nasuprot pričvrsne ploče 2, oslonjen u držaču 5 za okvir 6 naslona. Okvir 6 naslona nosi blazinu 7 za naslanjanje. On the skeleton 1 of the furniture, one fastening plate 2 is attached on both sides. On each fastening plate 2, two guides 3 and 4 are rotatably mounted, the end of which, which lies opposite the fastening plate 2, is supported in the holder 5 for the frame 6 of the backrest. The backrest frame 6 carries a pillow 7 for leaning.

Na držaču 5 je nadalje vodilica 8 zakretno uležištena i preko slijedeće vodilice 9 povezana držačem 10 za okvir 11 sjedala. Na okviru 11 sjedala leži blazina 12 za sjedenje. On the holder 5, the guide 8 is also pivotally mounted and via the next guide 9 is connected to the holder 10 for the frame 11 of the seat. On the frame 11 of the seat lies a cushion 12 for sitting.

Dvokraka poluga 13 ima točku 14 okretanja na vodilici 8. Jedan kraj poluge 13 je kod 15 okretljivo pričvršćen na držaču 10 i ima u suradnji sa zapornom kvakom 16 tri uskočne stepenice 17. Poluga 13 je na strani koja leži nasuprot uskočnim stepenicama 17 preko vodilice 18 povezana s držačem 5 okvira 6 naslona. The two-armed lever 13 has a turning point 14 on the guide 8. One end of the lever 13 is rotatably attached to the holder 10 at 15 and has, in cooperation with the locking handle 16, three snap-in steps 17. The lever 13 is on the side opposite the snap-in steps 17 over the guide 18 connected to the holder 5 of the frame 6 of the backrest.

U tri položaja za sjedenje u namještaju, koji su prikazani na slikama 2, 3 i 4, kraj poluge 13, koji leži nasuprot uskočnih stepenica 17, oslanja se na oslonac kojeg tvori čep 20. Kraj 19 poluge 13 je zato oblikovan stepenasto, pri čemu svaka stepenica odgovara drugom nagibu naslona. In the three seating positions in the furniture, which are shown in figures 2, 3 and 4, the end of the lever 13, which lies opposite the snap-in steps 17, rests on the support formed by the plug 20. The end 19 of the lever 13 is therefore shaped in a stepped manner, whereby each step corresponds to a different inclination of the backrest.

Kod okova prema izumu se time postiže, za razliku od drugih poznatih okova, besprijekorno oslanjanje u položajima za sjedenje u namještaju, pri čemu se ovo oslanjanje, što se tiče izradbe, postiže relativno jednostavno. With the fittings according to the invention, this achieves, in contrast to other known fittings, flawless support in seating positions in furniture, whereby this support, as far as production is concerned, is achieved relatively simply.
