Definitions

  • This invention relates to a piece of furniture that converts from either a sofa to a bed or a chair into a bed, these pieces of furniture are known as sofa-beds.
  • a sofa-bed comprising:
  • the use of the arms to serve as legs enables the sofa-bed to be maintained at an appropriate height when in the recliner position.
  • the enclosure of the frame in the filling material enables the sofa-bed to have a stylish appearance without unsightly pieces of frame being visible.
  • the arms on the upper seat section are preferably bolted on through the filling material.
  • the arms are preferably bolted on through the upholstery and filling material.
  • any appropriate fastening method that provides the required fastening effect may be employed. It should also be understood that in the precise region of the fastening there may be little or no filling material interposed between the frame of the upper seat section and the arms that are bolted to it; that does not, however, affect a user's comfort since the user does not place any weight in that region of the sofa-bed when using it.
  • the sofa-bed further includes legs on the lower seat section.
  • the legs on the lower seat section are preferably "bolted” on through the filling material and, in a case where upholstery encloses the filling material, through the upholstery and filling material.
  • the upper seat section is attached to the lower seat section by means of a link allowing folding of the frame inside the filling material.
  • a link By providing a link in the connection it becomes much simpler to provide a satisfactory arrangement.
  • a first end of the link is pivotably connected to the upper seat section and a second, opposite, end of the link is pivotably connected to the lower seat section.
  • the link pivots through about a right angle relative to the lower seat section and the upper seat section also pivots through about a right angle relative to the link, when the frame is moved from the first seat position to the second recliner position.
  • the angle need not be exactly a right angle and may, for example, be as little as 70 degrees or as much as 110 degrees in each case. If the angle of pivoting at one end of the link is relatively high, then the angle of pivoting at the other end of the link is preferably relatively low. In an embodiment of the invention described with reference to the drawings the total angle of pivoting of the upper seat section relative to the lower seat section is a little over 180°.
  • the range of pivoting movement of the link relative to the lower seat section is restricted to about a right angle and it is preferred that the range of pivoting movement of the upper seat section relative to the link is restricted to about a right angle.
  • Such restriction facilitates the movement by a user of the upper seat section when converting the sofa-bed.
  • the restriction of pivoting of the upper seat section relative to the link is of additional advantage when the frame is in the first seat position because it precludes undesirable forward sliding movement of the upper seat section over the lower seat section.
  • the angle to which pivoting is restricted need not be exactly a right angle and may, for example, be as little as 70 degrees or as much as 110 degrees in each case.
  • the first and second ends of the link are juxtaposed to frame members of the upper seat section and the lower seat section respectively, and transversely extending members fixed to respective ends of the link and projecting into the path of pivoting of the frame members limit the range of pivoting movement.
  • the link may comprise a pair of members on opposite sides of the sofa-bed, each member being juxtaposed to a respective frame member of each of the upper seat section and the lower seat section.
  • the frame is adjustable to several positions.
  • the back section of the frame is pivotably connected to the lower seat section by a connection that allows the back section to be held at a variety of inclinations to the lower seat section and also allows the back section to adopt a horizontal orientation.
  • Such connection means are known per se .
  • a sofa-bed that comprises a frame that is adjustable to several positions but which is entirely enclosed in filling material, enabling the product to be converted from chair/sofa to bed and back to chair/sofa, without the necessity of lifting off or re-arranging cushions or mattress.
  • a sofa-bed where the frame is entirely enclosed in the filling material.
  • the dotted lines in various drawings show the bounds of filling material 20 around the frame of the sofa-bed, the filling material being bounded by upholstery.
  • the sofa-bed has a frame comprising three main sections: an upper seat section 1, a lower seat section 2 and a back section 3.
  • the lower seat section 2 is supported off the ground by means of a pair of bolt-on legs 4 secured by bolts 5.
  • the bolts go through the upholstery and the filling material. As shown they extend upwardly through the legs 4 into the lower seat section 2.
  • the upper seat section 1 has arms 6 which become the legs when the upper seat section is lifted up and laid out as a recliner or bed.
  • the arms 6 are bolted on through the upholstery and the filling material 20 by means of bolts 7 which pass horizontally through a part 6A of each arm and into the upper seat section 1.
  • the upper seat section 1 and the lower seat section 2 are connected by means of a link 8.
  • the back section 3 is attached to the lower seat section 2 by means of a ratchet coupling 9 of a kind known per se.
  • the coupling allows the back section 3 to be supported at any of a variety of inclinations to the horizontal, and also in a horizontal orientation.
  • legs 10 which may themselves be pivotable as indicated by an arrow in Fig. 3, so as to be movable between a stowed position and the position shown in Fig. 3.
  • Figs. 6A and 6B show in more detail the connection of frame members of the upper seat section 1, the link 8 and the lower seat section 2.
  • Each frame member is formed of tube, in this particular example square tube.
  • a first end 8A of the link 8 is pivotably connected by a pin 11 to the end of the upper seat section 1 and similarly a second, opposite, end 8B of the link 8 is pivotably connected by a pin 12 to the end of the lower seat section 2.
  • the ends 8A, 8B of the link 8 are juxtaposed to the frame members of the upper and lower seat sections 1, 2 to which they are pivotably connected by the pins 11, 12.
  • Stop bar 13 is welded to the link 8 in the region of its first end 8A and, as shown in Fig.
  • stop bar 14 is welded to the link 8 in the region of its second end 8B and, as shown in Fig. 6B, projects into the path of the frame member of the lower seat section 2, thereby limiting its angle of pivoting to about a right angle.
  • a user can simply convert the sofa-bed of Fig. 1 shown in its first seat position to the sofa-bed of Fig. 3 shown in a recliner position.
  • the user simply lifts the upper seat section 2 by one or both of the arms 6 and flips the upper seat section over onto the ground. That action is illustrated in Fig. 2 where both positions of the seat section 1 are shown.
  • the limited range of pivoting of the link 8 relative to the seat sections 1 and 2 facilitates this movement. Also it may be noted that the limited range of movement prevents the upper seat section 1 sliding forwards (to the left as seen in Fig. 1) when the seat is in the position shown in Fig.1.
  • the sofa-bed is in the position shown in Fig. 3, namely a recliner position.
  • the amount of the recline can be adjusted as desired by virtue of the ratchet coupling 9 between the back section 3 and the lower seat section 2 and for use as a bed a particular recliner position is adopted in which the back section 3 is horizontal.
  • the legs 10 may be swung out to provide additional support for the back section 3.
  • Fig. 5 it can be seen that the particular embodiment illustrated is a chair. It will be understood, however, that substantially the same design can be applied to a wider seat which would then commonly be referred to as a sofa.
  • the filling material entirely encloses the frame.
  • the filling material boundary is shown in dotted outline as substantially coincident with the bottom of the frame section 2, but it should be understood that this only applies where the legs 4 are immediately adjacent to the lower seat section 2. Away from that region the filling 5 material extends below the bottom of the frame section 2.
  • the legs 4 may take a wide variety of forms including that of a swivel base.
  • the arms 6 may be of any desired shape or size consistent with their use as supports for the upper seat section when the upper seat section is in the recliner position; for example, they may be upholstered and may be much bulkier than the arms shown in the drawings.
