Definitions

  • the present invention relates to a convertible sofa-bed structure.
  • the problem upon which the present invention is based is that of devising a structure of the type specified which has structural and functional characteristics such as to overcome the aforementioned problems mentioned with reference to the prior art.
  • a convertible sofa-bed structure is generally indicated 1.
  • the structure 1 comprises a rectangular base 2 having long sides of a length substantially equal to the width of a double bed and short sides of a length equal to half of the length of a bed, reduced by a predetermined amount, indicated A.
  • the base 2 is supported on the ground by legs 3 disposed substantially at the ends of the sort sides.
  • the base 2 On the short sides, the base 2 carries respective rails, both indicated 4. Each rail 4 has a depression 5 disposed at a front end 4a.
  • the structure 1 comprises a telescopically-extendable platform 6 which comprises a first substantially rectangular, plate-like element 7, and a second substantially rectangular, plate-like element 8.
  • the elements 7 and 8 have long sides of a length substantially equal to the width of a double bed and short sides of a length substantially equal to half of the length of a bed and defining a depth, indicated P.
  • the first element 7 projects from the base 2 with a overhang of the above-mentioned amount A, and can be pulled out of the base 2 like a drawer from a retracted position to an extended position, for a predetermined travel S equal to the difference between half of the length of a bed, indicated P, and the depth of a sofa, indicated D.
  • the second plate-like element 8 can be moved like a drawer relative to the first plate-like element 7 between a position in which it is disposed substantially on top of the first element 7 and an extended position in which it is arranged substantially as an extension thereof.
  • the first element 7 has, at a rear end, a thin head portion 9 having a limited height substantially equal to twice the thickness M of a mattress 10.
  • the mattress 10 is formed by two identical rectangular mattresses 10a and 10b each having a length equal to the width of a double bed and a width equal to half of the length of a bed.
  • the two mattresses 10a and 10b are connected to one another in a substantially hinged manner by suitable stitching 11 extending along two respective long edges 12a and 12b.
  • the two mattresses 10a and 10b open like book to form, when opened out, a bed mattress 10, completed by pillows 13, when the element 8 is pulled out of the element 7 to form a bed platform 6 which, in the embodiment shown, is for a double bed.
  • the two mattresses 10a and 10b are folded onto one another to form a folded sofa pad 10 when the element 8 is superimposed on the element 7 to form a sofa platform 7.
  • the structure 1 is completed by a backrest 14 and by opposed arms 15 fixed to the base 2 by means of brackets 16.
  • the backrest 14 extends over the base 2 like a bridge so as to define a passageway 17 for housing the rear end of the element 7 with the head portion 9 and the rear end of the element 8, as well as the folded-up mattress 10.
  • the backrest 14 has a thickness B substantially equal to the travel S. Cushions 14a lean on the backrest 14a, if desired.
  • the first plate-like element 7 is constituted by a rectangular metal frame 18 with an L-shaped cross-section having vertical and horizontal flanges 18a and 18b, respectively.
  • the frame 18 comprises, on each short side, two aligned wheels 19 and 20 engaged on respective rails of the two rails 4, and a further, tyred wheel 21, which is engaged on the ground and is set back relative to the front end of the element 7 in the region of the projecting portion A and is also set back inwardly relative to the respective shorter side, so as to be hidden from view.
  • the wheel 20 falls into the depression 5 and thus constitutes a member for stopping the element 7 in the extended position.
  • the element 7 is coupled for rolling movement on the base.
  • the first element 7 comprises a plurality of strips 22 extending parallel to the short sides and arranged lying flat at regular intervals.
  • the second element 8 comprises a rectangular frame 23 with a box-like cross-section. On each short side, in the vicinity of the rear end, the frame 23 has a wheel 24 which is engaged on the horizontal flange 18b of the L-shaped cross-section of the frame 18.
  • the frame 23 also comprises a tyred wheel 25 which bears on the ground in a position set back relative to a respective short side and set back relative to the front end of the element 8.
  • the tyred wheels 25 are disposed beside the tyred wheels 21 on the inner sides thereof when the elements 7 and 8 are disposed on top of one another, and are thus also hidden from view.
  • the element 8 is coupled for rolling movement on the element 7.
  • the second element 8 comprises a plurality of strips 26 which extend parallel to the short sides and are arranged lying flat at regular intervals so as to fit between the strips 22, forming a substantially continual surface therewith when the elements 7 and 8 are disposed on top of one another.
  • a rear side 23a of the frame 23 abuts a front side 18c of the frame 18 in a mutual stopping arrangement, thus preventing removal of the element 8 from the element 7.
  • a suitable opening 27 is formed in the vertical flange 18a of the front side 18c of the frame 18 for the sliding of the box-like cross-section of each short side of the frame 23.
  • the second plate-like element 8 when the second plate-like element 8 is in the position in which it is arranged substantially as an extension of the first plate-like element 7, it is connected in a substantially hinged manner such that any incorrect operation to lift the front end of the second element 8 can freely be translated into an angular movement of the second element 8 relative to the first element 7, this movement being generally of no use but in any case being completely free of any danger of breakage of the structure.
  • the structure 1 adopts the sofa configuration la when the element 7 is retracted in the base 2 and the element 8 is superimposed thereon, the mattress being in the folded-up position, as shown in Figures 1 and 2.
  • the structure 1 adopts the lounger configuration 1b in which the platform has an increased depth equal to half of the length of a bed, this configuration thus being particularly suitable for supporting the user's extended legs, as can be seen in Figures 3 and 4.
  • the structure 1 adopts the bed configuration lc, as shown in Figures 5 and 6.
  • the main advantage of the structure according to the present invention lies in its structural simplicity and ease of operation.
  • the structure according to the invention is also favourable from the safety point of view since the moving parts are always in stable positions and there is no possibility of sudden undesired movements not related to the user's wishes.
  • a further advantage of the structure according to the present invention lies in its versatility, by virtue of which the structure can be transformed from a sofa to a bed and vice versa, passing through a further configuration, that is, through a lounger configuration.
  • a further advantage of the structure according to the present invention is that it can give rise to a sofa, to a lounger and to a bed, all of which also have an aesthetically pleasing appearance.
  • the structure according to the invention can also give rise to an arm-chair, to a single lounger, and to a single bed.
