Description

Izum se odnosi na armaturu za fotelju, koja se može preobraziti u krevet i koja ima ladicu koju se može izvući iz položaja ispod jastuka za sjedenje, u kojoj se nalazi dodatni jastuk, koji se nakon izvlačenja ladice pomoću armature može podignuti iz ladice u visinu jastuka za sjedenje, i u tom položaju je on na svojoj prednjoj strani poduprt na prednji dio ladice, pri čemu armatura ima krakove, koji na jednom kraju djeluju na ladicu, a na drugom kraj u djeluju na središnje područje dodatnog jastuka, pri čemu, nadalje, u području stražnjeg kraja dodatnog jastuka se nalaze ležaj i upravljača, koji se iza njega mogu zakrenuti prema dolje za približno 180° iz položaja koji je u spuštenom položaju dodatnog jastuka usmjeren prema gore, i spojeni su s još jednim parom daljnjih upravljača koji imaju ležaj na ladici. The invention relates to an armature for an armchair, which can be transformed into a bed and which has a drawer that can be pulled out from under the seat cushion, in which there is an additional pillow, which, after pulling out the drawer, can be raised from the drawer to the height of the pillow by means of the armature for sitting, and in this position it is supported on its front side on the front part of the drawer, whereby the armature has arms, which at one end act on the drawer, and at the other end in act on the central area of the additional cushion, while, furthermore, in in the area of the rear end of the additional cushion there is a bearing and a guide, which behind it can be rotated downwards by approximately 180° from a position that in the lowered position of the additional cushion is directed upwards, and is connected to another pair of further guides which have a bearing on the tray .

Takova armatura, koja je opisana u AT 403.981 B1, treba samo malu ugradbenu visinu i bočni dijelovi ladice ne moraju biti prilagođeni krivulji podizanja dodatnog jastuka. Zbog toga također nije potrebno da se dodatni jastuk izreže u području armature. Pri upotrebi armature prema izumu, pri preobrazbi fotelje, dodatni jastuk se podiže u ležeći položaj i dalje se pomiče prema naprijed, tako da ladica ostaje u dovoljnom zahvatu s postoljem fotelje i točno se vodi. Dodatna naprava za držanje u otvorenom položaju nije potrebna. Čak štoviše, u postojanom međupoložaju dodatni jastuk daje slobodan pristup do prostora za tvorbu kreveta. Such an armature, which is described in AT 403.981 B1, only needs a small installation height and the side parts of the drawer do not have to be adapted to the lifting curve of the additional cushion. Therefore, it is also not necessary to cut an additional cushion in the reinforcement area. When using the armature according to the invention, during the transformation of the armchair, the additional cushion is lifted into the lying position and further moved forward, so that the drawer remains in sufficient contact with the base of the armchair and is correctly guided. An additional device for holding in the open position is not required. Even more, in a stable intermediate position, the additional pillow provides free access to the space for making a bed.

Međutim, pokazalo se je da kod težeg dodatnog jastuka, čiji međupoložaj više nije tako stabilan, kao što se želi, postoji višestruka sklonost prema pregibanju. Cilj predloženog izuma je poboljšati izum prvog patentna tako, da armatura prema izumu bude prikladna također i za teški dodatni jastuk. To je postignuto time, da se između najmanje jadnog kraka i dodatnog jastuka nalazi vlačna opruga. However, it has been shown that with a heavier additional cushion, whose intermediate position is no longer as stable as desired, there is a multiple tendency towards buckling. The aim of the proposed invention is to improve the invention of the first patent so that the armature according to the invention is also suitable for a heavy additional cushion. This was achieved by placing a tension spring between the least poor arm and the additional cushion.

Kod takove armature najmanje jedna vlačna opruga osigurava međupoložaj dodatnog jastuka, u kojem je moguć pristup do prostora za tvorbu kreveta. With such an armature, at least one tension spring ensures the intermediate position of the additional pillow, in which access to the space for making the bed is possible.

Izum se u nastavku pobliže opisuje pomoću izvedbenog primjera prikazanog na crtežima, bez namjere ograničenja izuma na ta i primjer. Pri tome slike 1 do 3 prikazuju dio fotelje s armaturom, konstruiranom prema izumu, u različitim položajima, i slika 4 prikazuje pregledno nacrt armature koju se pri tome koristi. In the following, the invention is described in more detail using an exemplary embodiment shown in the drawings, without the intention of limiting the invention to this example. Figures 1 to 3 show a part of the armchair with armature, constructed according to the invention, in different positions, and Figure 4 shows an overview of the armature that is used.

Dio fotelje prikazan na crtežima ima postolje 1, na kojem se nalazi jastuk 2 za sjedenje. Ispod jastuka 2 za sjedenje u postolju fotelje 1 pomično je uvedena ladica 3. U ladicu 3 uložen je dodatni jastuk 4, koji se može podignuti, i koji je u položaju za ležanje, prikazanom na slici 3, poduprt na prednji dio 5 ladice 3. Ispod dodatnog jastuka 4 nalazi se prostor 6 za tvorbu kreveta. The part of the armchair shown in the drawings has a base 1, on which there is a cushion 2 for sitting. A drawer 3 is movably inserted under the cushion 2 for sitting in the base of the armchair 1. An additional pillow 4 is placed in the drawer 3, which can be lifted, and which is in the lying position, shown in Figure 3, supported on the front part 5 of the drawer 3. Under the additional pillow 4 there is a space 6 for making a bed.

Armatura prema izumu, koja služi za podizanje dodatnog jastuka 4, montirana je na obje strane fotelje, međutim opisuje se samo na jednoj strani. Prema tome, svaka strana ima kutni dio 7, koji je učvršćen na donjoj strani dodatnog jastuka 4 i ide od stražnjeg ruba sve do otprilike sredine debatnog jastuka 4. Zakretni krak 8, koju u položaju priprave (slika 1) leži otprilike vodoravno, s jedne strane djeluje u prednjem području kutnog dijela 7, a s druge strane djeluje u prednjem području ladice 3. U stražnjem području kutnog elementa 7 djeluje upravljač 9 jednog para upravljača, koji se poklapaju u položaju priprave i stoje približno okomito iza dodatnog jastuka 4. Upravljač 9 je iskrenut, pri čemu kraći krak 9' leži na dodatnom jastuku 4. Na dulji krak 9" djeluje daljnji upravljač 10, čiji suprotni kraj ima ležaj na ploči 11 učvršćenoj u ladici 3. Na upravljač 10 djeluje vlačna opruga 12. The armature according to the invention, which is used to raise the additional cushion 4, is mounted on both sides of the armchair, however, it is described only on one side. Therefore, each side has a corner part 7, which is fixed on the underside of the additional cushion 4 and goes from the rear edge up to approximately the middle of the debate cushion 4. The swivel arm 8, which in the preparation position (Figure 1) lies approximately horizontally, on one on the one hand, it acts in the front area of the corner part 7, and on the other hand, it acts in the front area of the drawer 3. In the back area of the corner element 7, the steering wheel 9 of a pair of steering wheels works, which coincide in the preparation position and stand approximately vertically behind the additional cushion 4. Steering wheel 9 is straight, with the shorter arm 9' resting on an additional cushion 4. The longer arm 9" is acted upon by a further steering wheel 10, the opposite end of which has a bearing on a plate 11 fixed in the drawer 3. A tension spring 12 acts on the steering wheel 10.

Vlačna opruga 14 je s jedne strane zakvačena s nastavkom 15, koji je spojen s kutnim elementom 7, a s druge strane je zakvačena s nastavkom 16, koji je spojen s krakom 8. The tension spring 14 is on one side attached to the extension 15, which is connected to the corner element 7, and on the other side it is attached to the extension 16, which is connected to the arm 8.

Da bi se fotelju promijenilo iz položaja za sjedenje u položaj za ležanje, najprije se ladicu 3 izvuče ispod jastuka za sjedenje 2 i time se dobije položaj prikazan na slici 1. Zatim se dodatni jastuk 4 podigne u svoje prednje područje. Pri tome se krak 8 zakrene prema gore (na crtežu u smjeru kazaljki na satu). Djelovanjem sile opruge 12 također se zakrene i upravljač 10 (na crtežu u smjeru kazaljki na satu), sve dok prilijeganjem na granične klinove 13 dosegne svoj krajnji položaj. U tom međupoložaju, prikazanom na slici 2, dodatni jastuk 4 strši koso prema gore, otprilike pod kutem od 45°, i time čini slobodnim pristup prostoru za stvaranje kreveta. U tom položaju opruga 14 podupire zauzeti položaj dodatnog jastuka 4, tako da također i kod težih dodatnih jastuka 4 ne može doći do pregibanja. In order to change the armchair from a sitting position to a lying position, first the drawer 3 is pulled out from under the seat cushion 2 and thus the position shown in figure 1 is obtained. Then the additional cushion 4 is raised to its front area. At the same time, arm 8 is rotated upwards (clockwise in the drawing). The action of the force of the spring 12 also rotates the steering wheel 10 (clockwise in the drawing), until it reaches its end position by touching the boundary pins 13. In this intermediate position, shown in Figure 2, the additional pillow 4 protrudes obliquely upwards, at an angle of approximately 45°, and thus provides free access to the space for creating a bed. In this position, the spring 14 supports the occupied position of the additional cushion 4, so that even with the heavier additional cushions 4, bending cannot occur.

Tek kod daljnjeg podizanja, odnosno izvlačenja dodatnog jastuka 4, upravljač 9 koji djeluje na kutni dio 7, podiže se od dodatnog jastuka 4 i opisuje otprilike polukružno kretanje (na crtežu suprotno smjeru kazaljki na satu). Pri tome, krak 8 se okreće najprije još u smjeru kazaljki na satu, međutim, prije nego dođe u položaj za ležanje prikazan na slici 3, on se okreće suprotno kazaljki na satu. U tom položaju za ležanje, dodatni jastuk 4 poduprt je svojim prednjim krajem na prednji dio 5 ladice 3. Na stražnjem kraju dodatni jastuk 4 je poduprt upravljačima 9 i 10, pri čemu upravljač 10 naliježe na graničnik 13. Only when the additional cushion 4 is further raised, i.e. pulled out, the steering wheel 9, which acts on the corner part 7, rises from the additional cushion 4 and describes an approximately semi-circular movement (counter-clockwise in the drawing). In doing so, the arm 8 first rotates clockwise, however, before reaching the lying position shown in Figure 3, it rotates counter-clockwise. In this lying position, the additional cushion 4 is supported by its front end on the front part 5 of the drawer 3. At the rear end, the additional cushion 4 is supported by the guides 9 and 10, whereby the guide 10 rests on the stop 13.

Promjena fotelje iz položaja za ležanje u položaj za sjedenje vrši se obrnutim redoslijedom prethodno opisanog postupka. Changing the armchair from a lying position to a sitting position is done in the reverse order of the previously described procedure.
