Definitions

  • the invention relates to a piece of furniture convertible from a seat into a bed, provided with an upper part and a support supporting this part and having four legs rigidly connected to one another by connecting parts, the legs being formed of two at least substantially U-shaped profiles which are disposed cross-wise.
  • a seat comprised of like components is described in FR-A-1180733, directed to a lounge-chair which can be installed in a large number of positions.
  • the seat according to said patent has however not been designed to be transformed into a furniture to be used as a bed. This due to the way in which the cross-wise disposed profiles forming the support are connected to one another by elements in the shape of armrests.
  • the invention has for an object to provide a piece of furniture convertible from a seat into a bed of the kind mentioned in the preamble, the support of which is relatively easy and cheap to manufacture and which offers nevertheless very good possibilities for a stable support of the piece of furniture, both in the sofa and in the bed position thereof.
  • the a piece of furniture convertible from a seat into a bed is characterized in that the above referred to profiles are irrotatably connected to one another by plates disposed on both lateral sides of the support, which plates are each connected at two places to the one U-shaped profile and at one of these places also to the other U-shaped profile, while each of the plates further supports at a third place the other U-shaped profile.
  • the plates are then preferably part of an operating mechanism for adjusting the upper part between a bed position and a seat position.
  • both U-shaped profiles are rigidly and irrotatably fixed to one another on each side only through three connections by means of plates which were already required for the operating mechanism of the upper part and only the shape of which has to be adapted for the function of attachment means.
  • locking members are advantageously formed on the plates which may engage irremovably at said third place in holes in the body of the other U-shaped profile.
  • the invention further embraces a support for use in the hereabove described piece of furniture.
  • Fig. 1 and 2 are very schematical side elevational views of the embodiment of the piece of furniture convertible from a seat into a bed according to the invention in the sofa position and in the bed position respectively, with only two frame components of the upper part being in particular indicated.
  • Fig. 3 is, on a larger scale, a side elevational view of an operating mechanism for adjusting the upper part between the sofa and bed position of the piece of furniture according to fig. 1 and 2.
  • Fig. 4 is a perspective view of the U-shaped profiles connected to one another for the support of the piece of furniture according to fig. 1 and 2.
  • Fig. 5, 6 and 7 show in different steps the final assembly of the support of the piece of furniture according to fig. 1 and 2, on a larger scale.
  • the drawings show very schematically an embodiment of the piece of furniture according to the invention, which is designed in this case as a sofa bed, which forms in the seat position a two or three seat sofa and in the bed position a double bed.
  • the piece of furniture can also be designed as a chair respectively a single bed or may even comprise other combinations.
  • an upper part 1 and a support 2 supporting this upper part can roughly be distinguished.
  • frame parts of the back portion 3 and the seat portion 4 are indicated very schematically.
  • the back portion 3 In the sofa position of the sofa bed according to fig. 1, the back portion 3 is directed obliquely upwards and the seat portion 4 is inclined backwards, while through a manipulation of an operating mechanism 5 represented very schematically in fig. 1-3, the back portion 3 and the seat portion 4 can be displaced and pivoted towards a horizontal bed position as illustrated in fig. 2.
  • the operating mechanism 5 comprises on both lateral sides a four bar system, one bar side of which being formed by a support for the back portion 3, which is connected through two bars 6 and 7 with a stationary bar side, which is a part of a side plate 8.
  • the further construction and functioning of the operating mechanism is not relevant for the present invention and is therefore not described in greater detail. Only the side plates 8 of the operating mechanism are an element of the invention and will be discussed further hereinafter.
  • the upper part 1 of the piece of furniture is supported by the support 2 which is essentially built up of two at least substantially U-shaped tubes 9 and 10, the body 11 of the one U-shaped tube 9 being shorter than the body 12 of the other U-shaped tube 10 in such a manner that the legs 13 of the U-shaped tube 9 serving as legs for the piece of furniture fit accurately between the legs 14 of the other U-shaped tube 10 serving also as legs and both U-shaped tubes 9 and 10 can be connected cross-wise to one another.
  • the upper part 1 is adjustably supported by the bodies 11 and 12 of the U-shaped tubes 9 and 10 in a not further indicated way, for example through support blocks 15. As shown, caps can further be applied onto the lowermost extremities of the legs 13 and 14.
  • both U-shaped tubes 9 and 10 can be pivoted in such a manner with respect to each other from a flat storage or transport position according to fig. 5 that, via the position according to fig. 6, the body 12 of the U-shaped tube 10 is going to lay finally in the position according to fig.
  • the invention provides a piece of furniture convertible from a seat into a bed, the support of which can be manufactured from very little components and in a very easy way, while the extremities of the legs 13 and 14 of the U-shaped tubes 9 and 10 provide in the depth direction of the piece of furniture a very large and therefore stable base for the piece of furniture, so that there is no risk for tipping over in the bed position of the piece of furniture.
  • the legs of the support do not trouble persons sitting on the piece of furniture in the sofa position, which support is moreover also a visually attractive entity.
