Definitions

  • the present invention relates to structures for sofa-bed or armchair-bed, and in particular to an improved structure which makes easier to the user the opening and closing of the bed.
  • Specific reference will be made hereafter to a sofa-bed but it is clear that what will be said applies also to an armchair-bed which simply has a smaller width.
  • the bedspring consists of three sections mutually hinged which are pulled out from the base of the sofa-bed and extend, in a direction orthogonal with respect to the width of the sofa-bed, to a position of complete opening and alignment to form the bed.
  • the object of the present invention is to provide a structure for sofa-bed or armchair-bed which overcomes the above-mentioned limits of prior art structures. This object is achieved by means of a structure having the characteristics disclosed in the main claim. Other advantageous features are disclosed in the dependent claims.
  • the main advantage of the present structure for sofa-bed is that of making much easier to the user to open and close the bed through a wheel-assisted sliding movement which replaces the raising movement.
  • a further advantage of this structure comes from the use of the base itself as first section of the bed, whereby the mobile structure is simple, light and compact and can be housed in a base of smaller height with respect to a conventional sofa-bed.
  • Still another advantage of this type of sofa-bed comes from the use of the sofa cushions themselves as mattress, whereby there is no problem of room taken up by the cushions during the use as bed and the mattress can be thicker with positive effects as to comfort and endurance.
  • a structure for sofa-bed includes a stationary base provided with legs G, as well as with internal sliding guides N, arranged along the bottom edge of sides A, in which there are engaged rollers P externally mounted on the sides M of a mobile structure supported by front wheels R.
  • the stationary base also includes a rear side on which there is mounted a back (not illustrated in the drawing), as well as springs or staves fixed to the front E and rear E' crossbars and/or to sides A.
  • crossbar T is the portion of the structure which is gripped by the user to pull the mobile portion out of the stationary portion by pulling outward in the direction of the arrow of fig.1 (the completely extracted position illustrated in fig.2 being defined by stops which are not shown).
  • the second sections consists of sides S joined by front D and rear D' crossbars, and it is pivoted at front pins X to the third section consisting of sides U joined by front C and rear C' crossbars.
  • this section includes two internal bars V, parallel to sides U, extending between crossbars C, C' and to which leg W is internally pivoted.
  • each parallelogram is made up of a bottom horizontal lever K, a front inclined lever K' and a rear inclined lever K", the fourth side consisting of sides S of the second section.
  • the front lever K' is pivoted between a pin H arranged close to the front crossbar D and a pin Z" at the front end of the horizontal lever K
  • the rear lever K" is pivoted between a pin H' on side S and the above-mentioned pin Z' at the rear end of the horizontal lever K.
  • connection between the parallelogram and sides M is achieved through short front J' and rear J" levers, which are pivoted at their bottom end to said sides M and at their top end to the middle of the inclined levers K' and K" respectively.
  • a further connection which provides stability to the movement of the parallelogram is achieved through long levers F, slightly inclined with respect to the horizontal, pivoted at their front end to pins I arranged around midlength of sides S and at their rear ends to the rear crossbar T'.
  • These levers F are substantially complanate with the horizontal levers K of the parallelograms and therefore external with respect to the raising levers Y which are pivoted at pins Z' on the inside of the parallelograms.
  • the third sections rests on leg W and the second section is perfectly aligned along the horizontal plane to said third section as well as to the stationary portion which acts as first section.
  • the front rods B have been rotated forward to an almost horizontal position by rotating levers L pivoted between the front levers K' of the parallelograms and said rods B so that the panel supported by the latter does not interfere with the third section (fig.4).
  • the springs and/or staves of the second and third section can not extend to sides S and U respectively.
  • the third section is provided with a bedspring extending between bars V and crossbars C, C', while the second section is provided with longitudinal staves mounted between crossbars D and D'.
  • the user finally longitudinally slides the sofa cushions, which are mutually joined, so that the seat cushion is positioned on the third section, the back cushion on the second section and the cushion on the rear of the back on the first section.
