Definitions

  • the invention relates to a convertible sofa with a rectangular seat and a rectangular back pivotally connected with its rear edge, the said sofa being preferably of the kind in which the sitting furniture is converted into bed furniture by raising the front edge of the seat, whereby the connected edges are pushed forwardly by means of guides provided in the side members of the sofa, and the back is swung down into a substantially horizontal position, whereas the seat is in a substantially vertical position, but is subsequently swung down into horizontal position and its front edge supported by legs which may be swung outwards.
  • each leg has an arm pivotally connected with a push rod extending beneath the seat and slidably received in a slit which is provided in a retaining member attached to the back and which carries a stop member adapted to abut the retaining member when the seat is swung down, the leg being furthermore connected with a spring adapted to pass the leg into returned position.
  • the retaining member may consist of a girder which extends parallelly with the end edge of the back to a certain point in front of its longitudinal edge and has an upwardly facing surface which at the front end of the member curves downwardly to form a forward-facing surface, the slit for the push rod extending over the curved surface and a part of the two other surfaces.
  • the push rod will, with the seat swung down, both with the sofa in the position of sitting furniture and in the position of bed furniture, be located substantially horizontally and will thus occupy a minimum of space in the sofa.
  • the pressure bar is simultaneously passed in a curved movement upwards through the slit so that its free end moves along a path lying beneath and as closely as possible to the two sofa parts.
  • FIGURE 1 shows a part of the convertible sofa with its seat swung up
  • FIGURE 2 is the same with the said part swung more downwards.
  • the sofa consists of an underpart 1 and two side mem bers 2, between which there is supported a back 3 and a seat 4.
  • the seat and the back are pivotally connected 3,278,951 Patented Oct. 18, 1966 with each other by means of hinged members 5 and is guided by means of guides provided in the side members 2.
  • the said guides are adapted in such manner that the sofa may be converted from an article of sitting furniture to an article of bed furniture by the user grasping beneath the front edge of the seat 4, swinging the said seat up into vertical position as shown in FIGURE 1.
  • the back slides forward and downward so that it is brought into horizontal position.
  • the remaining operation of converting the sofa into a bed furniture unit consists in swinging the seat in the opposite direction into horizontal position, whereby the back and the seat in combination form a horizontal twin bed.
  • a metal member 6 forming pivotal support for a supporting leg 7.
  • the attachment is of such kind that the leg can be swung out from the position shown in FIGURE 1, in which it is lying substantially along the end edge of the seat 4 in a vertical plane into a position in which the leg is at right angles to the plane of the seat 4.
  • the pivot about which the leg turns is surrounded by a helical spring which is adapted to counteract the said outward movement of the leg, that is to urge the leg to turn inwards towards the inoperative position indicated in FIGURE 1.
  • the leg is provided with an arm 9 which is pivotally connected with a push rod 10 with attached stop member 11.
  • the said member may be adjusted in any desired position on the push rod 10, being secured by means of a screw.
  • the lower part 12 of the push rod 10 is passed through a slit 13 provided in a retaining member- 14 which consists of an angular girder screwed on to the bottom of the back 3 and having an upward-facing horizontal surface 15 which at the end of the member is curving down- Wards to form a forward-facing surface 16.
  • the slit 13 extends over the curved section and a part of the horizontal surface and the vertical surface as shown in the figures.
  • the mechanism operates in the following manner: When the sofa is in the position in which it serves as sitting furniture, the seat 4 is substantially horizontal and the back 3 substantially vertical, e.g. rearwardly inclined. In this position the push rod 10 will be substantially horizontally disposed, extending through that part of the slit 13 which is formed in the forward-facing end surface of the girder 15. The leg 7 is in its inward-turned position, indicated in FIGURE 1.
  • the user grasps as mentioned beneath the front edge of the seat 4, swinging the said seat into the substantially vertical position indicated in FIG- URE 1, whereby the push rod 10 is withdrawn from the slit 13.
  • the back 3 slides downwards and forwards as mentioned into the position indicated in FIGURE 1, where it is horizontal.
  • the mechanism is of simplest possible design.
  • a convertible sofa adaptable to be connected from a seat form to a bed form said sofa comprising a seat member and a back member, said seat member being connected at its rear edge to the lower edge of said back member and each movable from a seat position to a horizontal bed position, said seat member provided on its underside adjacent its forward edge with pivotal support means, adapted to be pivotally moved from a first position wherein said support means lies in a plane substantially parallel to the plane of said seat member to a second position wherein said support means lies in a plane normal to the plane of said seat member, arm means secured to said support means for pivotal connection with push rod means extending beneath said seat member, retaining means secured at the lower edge of said back member and extending forwardly therefrom in a plane parallel with said seat member, said retaining means having an upwardly facing surface curving downwardly at the free end thereof to provide a forwardly facing surface, said retaining means 4 provided with a slit means extending over the curved portion thereof and over
