Abstract

In a seat convertible into a bed, part of the bed surface takes the form of two cushions (6, 7) fitted in a pull-out section (5) which, with the unit in the seating position, lie with their upholstered sides against each other. To provide the bed surface, the upper cushion (7), fitted with a folding foot (F), can be pivoted about a horizontal spindle (9) fitted in the pull-out section (5) and the lower cushion (6) can be raised by means of an articulated brace (8). To prevent damage to the cushions, the horizontal spindle (9) can slide by means of a substantially vertical guide (14) and accompanies the articulated brace (8) in its movement.

Description

V posteljo pretvorljivo sedežno pohištvoConvertible seat furniture

Izum se nanaša na sedežno pohištvo, ki se ga da pretvoriti v posteljo, pri katerem se del ležalne površine tvori z dvema, v izvlečnem delu uležaj enima blazinama, ki v sedežnem položaju pohištva nalegata s svojima oblazinjenima ploskvama druga na drugo, pri čemer je z izvihtljivo nogo opremljena zgornja blazina, za tvorbo ležalne površine, zavihtljiva okoli na izvlečnem delu razporejene vodoravne osi, spodnja blazina pa je s pomočjo zgibnega okovja dvigljiva v izvlečnem delu.The invention relates to seat furniture which can be converted into a bed, in which a part of the bearing surface is formed by two cushions in the extraction part, which in the seating position of the furniture rest with their upholstered surfaces, with an extending leg fitted with an upper cushion for forming a recumbent surface, pivoting about a horizontal axis arranged on the extender portion, and the lower cushion being lifted in the extending portion by means of a hinged fitting.

Znano je pretvorljivo pohištvo, pri katerem postaneta z izvlečenjem voza ali izvlečnega dela dve, v tem vozu shranjeni blazini dostopni. Na nožni strani nahajajoča se blazina je s pomočjo šarnirja zgibno pritrjena na prednjo obrobo voza in se z zavihtitvijo za 180° prinese v ležalni položaj. Srednja blazina, ki v shranjenem položaju leži pod nožno blazino, se s pomočjo zgibnega okovja dvigne iz voza in tako postavi v ležalni položaj, da leži med sedežnim delom in nožno blazino. Takšno pohištvo se po eni strani odlikuje z enostavnimi pretvorbenimi funkcijami, po drugi strani pa z oblazinjenjem, ki se ga da enostavno izdelati. Nadalje je s tovrstno razporeditvijo dosegljiv tudi položaj za gledanje TV (TV položaj), in to v obliki, da se nožno blazino sicer prinese v ležalni položaj, srednjo blazino pa pusti v shranjenem položaju, s čimer se da nožno blazino s potiskom voza ali izvlečnega dela neposredno potisniti k sedežni blazini. Sedaj je mogoče sesti na to pohištvo, noge pa opreti na izvihteno nožno blazino.Convertible furniture is known in which the two cushions stored in that cart become accessible by pulling out the cart or the pull-out part. The cushion located on the foot side is hinged to the front edge of the car by means of a hinge and is brought to a supine position by 180 °. The middle cushion, which is stored under the foot cushion in the stored position, is lifted out of the carriage by means of a hinged fitting and placed in a lying position so that it lies between the seat and the foot cushion. Such furniture is distinguished on the one hand by simple conversion functions and, on the other hand, by easy-to-make upholstery. Furthermore, this arrangement also achieves a TV viewing position in the form of bringing the foot cushion to a recumbent position and leaving the middle cushion in a stored position, thereby providing a foot cushion by pushing the cart or pull out. work directly to the seat cushion. It is now possible to sit on this furniture and rest your feet on a twisted foot pillow.

Pri znanem pohištvu se je kot pomanjkljivo pokazalo, da se z višinskim položajem šarnirja nožne blazine, ki je večinoma šibkejša kot druga blazina, ne da namestiti v “7 t-® ležalno višino druge blazine. Nadalje naj bi bil šarnir s svojim vrtiščem razporejen karseda visoko, zaradi česar lahko pri TV položaju pride v prednjem območju do poškodovanja sedežne blazine. Pri spremembi šarnirskega kraka oz. višinskega položaja tega šarnirja bi se sicer nožno blazino dalo namestiti v višino ležalnega položaja, vendar se zato v shranjenem položaju prostora v vozu ne da izkoristiti.For the known furniture, it has been shown that the hinge height of the foot cushion, which is mostly weaker than the other cushion, does not fit into the "7 t-® bearing height of the second cushion". Furthermore, the hinge with its pivot should be positioned as high as possible, which can cause damage to the seat cushion when the TV position is in the front area. When changing the hinge arm or. The height of this hinge would otherwise allow the foot cushion to be installed in the height of the reclining position, but therefore it cannot be used in the stored position of the carriage.

Izum si je zastavil cilj izogniti se pomanjkljivostim znanega pohištva in pohištvo uvodoma omenjene vrste zlasti tako zasnovati, da je pri največji izrabi razpoložljivega prostora poškodovanje blazin praktično izključeno. Ta cilj se doseže s tem, da je vodoravna os s pomočjo v bistvu navpičnega vodila premakljivo uležajena in gibljivo povezana z zgibnim okovjem. S to razporeditvijo se doseže, da leži vodoravna os v shranjenem položaju nujno nižje kakor v ležalnem položaju.The invention aims to avoid the disadvantages of the known furniture and to design the furniture of the aforementioned type in particular in such a way that damage to the cushions is practically excluded in the maximum utilization of the available space. This objective is achieved by the fact that the horizontal axis is movably supported and pivotally connected to the articulated fitting by means of a substantially vertical guide. This arrangement achieves that the horizontal axis in the stored position is necessarily lower than in the lying position.

Pri smotrnem izvedbenem primeru izuma se vodoravno os tvori z dvema stranskima šamiijema, katerih prvi krak je premakljivo voden na izvlečnem delu in preko roke povezan s po višini gibljivim členom zgibnega okovja.In a preferred embodiment of the invention, the horizontal axis is formed by two lateral shamis, the first arm of which is movably guided on the extraction part and connected by a hand to the height-movable member of the articulating fittings.

Nadaljnja pomanjkljivost znanega pohištva leži v tem, da pri izvihtitvi podporne noge v izvlečenem položaju, in sicer tako v TV kot tudi v ležalnem položaju, nalega šarnir na prednjo ploščo, zaradi česar lahko pride do poškodovanja prednje plošče oz. deformiranja šarniija. To pomanjkljivost se da pri izvedbenem primeru po izumu odpraviti s tem, da sledi povezava med vodoravno osjo in zgibnim okovjem preko podolgovate luknje. Če se pri tem izvedbenem primeru podporne noge ne izvihti, lahko vodoravna os oz. šarnirski ležaj zdrsne navzgor vzdolž podolgovate luknje, s čimer se zanesljivo izognemo poškodovanju oz. deformaciji.A further disadvantage of the known furniture lies in the fact that when the support leg is twisted in the extended position, both in the TV and in the lying position, it puts the hinge on the front panel, which can damage the front panel or the front panel. deformation of the hinge. This disadvantage can be eliminated in the embodiment of the invention by following the connection between the horizontal axis and the articulated fitting via an elongated hole. If the support leg does not bend in this embodiment, the horizontal axis or the hinge bearing slides up along the elongated hole to reliably avoid damage or damage. deformation.

Izum je v nadaljevanju pobliže opisan s pomočjo na risbah predstavljenih izvedbenih primerov, ne da bi se izum omejevalo na te izvedbene primere, pri čemer kaže sl. 1 pohištvo po izumu v ležalnem položaju, v shematskem pogledu s strani, sl. 2 do 5 končni del izvlečnega dela, v povečanem merilu, z razporeditvijo šarnitjev po izumu, in sicer sl. 2 v sedežnem položaju, sl. 3 v TV položaju, na sl. 4 v ležalnem položaju in na sl. 5 v položaju, pri katerem je nožna blazina prinešena do sedežne blazine in usmerjena nagnjeno navzdol.The invention will now be described in more detail with the aid of the drawings shown in the drawings, without limiting the invention to those embodiments, with FIG. 1 shows the furniture according to the invention in a recumbent position, in schematic side view; FIG. 2 to 5 show the final portion of the extraction portion, enlarged scale, with the arrangement of the hinges according to the invention, FIG. 2 in the seated position, FIG. 3 in the TV position, FIG. 4 in a supine position and in FIG. 5 in the position where the foot cushion is brought to the seat cushion and is pointing downward.

Po sl. 1 nosi pohištveno ogrodje 1 fiksno hrbtno blazino 2 in prav tako fiksno sedežno blazino 3. V vodilu 4 pohištvenega ogrodja 1 je premakljiv izvlečni del 5, ki sprejme blazini 6 in 7. Blazina 6 je v izvlečnem delu dvigljiva preko zgibnega okovja 8, blazina 7 pa je preko vodoravne osi 9 zavihtljivo povezana s prednjo ploščo 10 izvlečnega dela.According to FIG. 1 carries a furniture frame 1 a fixed back cushion 2 and also a fixed seat cushion 3. In the guide 4 of the furniture frame 1 there is a movable pull-out part 5 which receives the cushions 6 and 7. The cushion 6 is liftable in the pull-out part through the hinge fittings 8, the cushion 7 however, it is pivotally connected to the front panel 10 of the drawbar via the horizontal axis 9.

Zgibno okovje 8 obsega v bistvu dva zavihtljiva člena 11 in 12, pri čemer se dviganje blazine 6 olajša z vzmetjo 13.The articulation fitting 8 consists essentially of two swivel members 11 and 12, the lifting of the cushion 6 being facilitated by a spring 13.

Vodoravna os 9 je tvorjena z dvema šarnirjema, katerih prva kraka 14 sta stransko višinsko gibljivo vodena na prednji plošči 10. Druga kraka 15 sta pritrjena na okviru blazine 7. Kraka 14 obsegata nastavek 16, na katerem je zgibno pritrjen prvi konec roke 17, katere drugi konec je zavihtljivo povezan s členom 12 zgibnega okovja 8.The horizontal axis 9 is formed by two hinges, the first arms 14 of which are laterally movable in height guided on the front panel 10. The second arms 15 are fixed on the frame of the cushion 7. The arms 14 comprise a nozzle 16 on which the first end of the arm 17 is articulated, which the other end is pivotally connected to Article 12 of the hinge fittings 8.

Ta del izvlečnega dela 5 je pobliže predstavljen na sl. 1 do 5, pri čemer, za razliko od izvedbenega primera po sl. 1, sledi povezava roke 17 z nastavkom 16 preko podolgovate luknje.This part of the extraction portion 5 is presented in more detail in FIG. 1 to 5, wherein, in contrast to the embodiment of FIG. 1, the connection of the arm 17 to the attachment 16 is followed by an elongated hole.

Kot je že bilo pojasnjeno sta na prednji plošči 10 stransko razporejena dva šarnirja, ki skupaj tvorita os 9. Zaradi enostavnosti je v nadaljevanju opisan le en šamir.As explained above, two hinges are laterally arranged on the front panel 10, which together form the axis 9. For the sake of simplicity, only one hinge is described below.

Iz sl. 2 do 5 je razvidno, da je krak 14 višinsko gibljivo voden na s prednjo ploščo povezani, kot črka C zasnovani tirnici 18. V položaju po sl. 2, 3 in 4 deluje podolgovata luknja 19 kot enostavna vrtina, kajti os 20 se opira le na spodnjem koncu podolgovate luknje 19. Podolgovata luknja deluje potemtakem le v položaju po sl. 5.From FIG. 2 to 5, it is shown that the arm 14 is movable in height and is connected to the front panel, connected to the letter C by the rail 18. In the position of FIG. 2, 3 and 4, the elongated hole 19 acts as a simple bore, since the axis 20 rests only at the lower end of the elongated hole 19. The elongated hole thus acts only in the position of FIG. 5.

V nadaljevanju je opisan način delovanja pohištva po izumu:The following describes the operation of the furniture according to the invention:

V sedežnem ali shranjenem položaju, predstavljenem na sl. 2, se člen 12 zgibnega okovja nahaja v približno vodoravnem položaju tesno nad ravnino tal. Nad njim leži v spuščenem položaju blazina 6, na njej pa za 180° zavihtena blazina 7. Izvlečni del 5 je potisnjen pod sedežno blazino 3.In the seated or stored position shown in FIG. 2, the articulation 12 of the articulated fittings is located approximately horizontal above the ground plane. Above it, the cushion 6 is lowered, and the cushion 7 is rotated 180 ° on it. The extraction part 5 is pushed under the seat cushion 3.

Os 9 je torej v spuščenem položaju in pri izvlečenju izvlečnega dela se zato odsek šarnirja, ki tvori os 9, zadrži na spodnjem robu okvira sedežne blazine 3.The axis 9 is therefore in a lowered position and, when the extraction part is pulled out, the hinge section constituting the axis 9 is thus retained at the lower edge of the seat cushion frame 3.

Blazino 7 se da sedaj z zavihtitvijo za približno 180° prinesti v položaj, vzporedenThe cushion 7 can now be brought to a parallel position by a rotation of about 180 °

112 4 ležalnemu položaju, vendar nekoliko bolj spuščen (sl. 3). Šele z dvigom blazine 6 se člen 12 zgibnega okovja zavihti navzgor in s tem dvigne roko 17. S tem se potisne navzgor tudi šamirja oz. os 9, dokler ni blazina 7 prinešena v višino ležalnega položaja (sl. 4).112 4 lying down but slightly lower (Fig. 3). Only by lifting the cushion 6 does the articulation 12 of the articulation mount swivel upwards, thereby raising the arm 17. This also pushes the hinge or the hinge up. axis 9 until the cushion 7 is brought in the height of the recumbent position (Fig. 4).

Če se podporno nogo F v TV položaju ne izvihti, pritisne krak 15 na prednjo ploščo 10, šamir pa zdrsne vzdolž podolgovate luknje 19 roke 17. S tem se doseže nadaljnji položaj z nagnjeno navzdol spuščajočo se blazino 7 (sl. 5).If the support leg F is not disengaged in the TV position, the boom 15 is pressed against the front panel 10, and the shamir slides along the elongated hole 19 of the arm 17. This achieves a further position with the downward sloping cushion 7 (Fig. 5).

V okviru izuma je mogoča vrsta sprememb. Tako se da uporabiti drugačno zgibno okovje 8 oz. povezava osi 9 s členom zgibnega okovja je mogoča na drug način.A number of variations are possible within the scope of the invention. Thus, a different hinge fitting of 8 or 8 can be used. the connection of the axis 9 to the articulation member is possible in another way.
