Definitions

  • the present invention relates to settee capable of being converted into beds.
  • the invention relates to convertible settees of the type comprising a fixed frame constituted by two end pieces forming the arms of the settee and interconnected by spars and a movable frame which carries on one face the seat and the back of the settee and on the opposite face a mattress for use as a bed, the movable frame being connected to the fixed frame in correspondence with the two end pieces, so as to permit rotation of the movable frame by 180 in both directions about a longitudinal axis between a position for use as a settee and a position for use as a bed.
  • An object of this invention is to provide a convertible bed-settee unit of the abovementioned type, in which the thickness and height of the end pieces acting as arms, and the thickness of the arms, are reduced, keeping within acceptable limits the dimensions of the bed whilst reducing the overall dimensions of the unit'
  • a further object of this invention is to provide a convertible bed-settee unit of the abovementioned type, constituted of a reduced number of parts and having good stability in its two different positions of use.
  • Another object of this invention is to produce a convertible bed-settee unit, in which the turning-over operation to change from one position of use to the other is simple and easy to carry out and does not require excessive muscular effort.
  • the convertible bed-settee unit comprises a fixed frame having two interconnected end portions and a movable frame, adapted to be rotated about a longitudinal axis and carrying on one face a seat and a back for use as a settee and on the other face a mattress support for use as a bed, wherein the improvement consists in that the unit further include's:

  • FIG. 15 is a transverse cross section of the unit shown in FIGS. 12 and 14, in the position of use as a settee.
  • the convertible bed-settee unit comprises a fixed frame constituted by two end sub frames 1 interconnected by longitudinal spars 1a.
  • the end sub-frames l are made so as to form two end pieces 2 having a reduced height and thickness and acting as arms.
  • each end sub-frame 1 of the fixed frame has integral with it two parallel horizontal guides 3, 4 between which a flanged roller 10 is engaged, the roller being carried with spring action by a stirrup 9 integral with a movable frame 5.
  • the movable frame 5 carries on one face a seat 6 and a back 8 for use as a settee and on the opposite face a mattress 7 for use as bed.
  • the movable frame 5 can be rotated through 180 in both directions about a longitudinal axis, the movable frame being articulated to the fixed frame in correspondence with the said longitudinal axis, which passes through the two flanged rollers 10, the latter being situated in eccentric positions with respect to the longitudinal centre-line of the movable frame itself.
  • Each roller 10 is mounted on a shaft which is fixed to a lateral appendix ll whichprojects towards the exterior and extends parallel to the respective end member of the movable frames 5.
  • the movable frame 5 is moreover connected to the fixed frame at each end through a three armed lever 13 one arm of which is articulated to a pivot 12 situated on the centre line of the frame 5, a second arm of which is articulated to a pivot 14 situated at one end of the respective end sub-frame l, a third arm 15 of which is subject to the action of a helical spring 16 anchored to a fixed support 17 on the sub-frame.
  • the spring 16 is tensioned in both the positions of use of the unit, that is, use as a settee and use as a bed, and its tension is relieved during transition between these positions to facilitate the transition and reduce the muscular. effort required for effecting the transition.
  • rollers 10 run along the horizontal guides 3 and 4 in the two fixed end subframes 1 whilst the three-armed levers l3 oscillate, first in an upwards sense and then in a downwards sense, enabling the movable frame 5 to rotate through 180.
  • Each stirrup 9 of the movable frame 5 carries a projecting appendix to which is articulated, through a pivot pin 19, a curved arm 20 integral with the frame structure 21 of the back 8.
  • the back frame structure 21 can thus move with respect to the movable frame 5 from an erect position (FIG. 2) to a collapsed horizontal position by rocking about the pivot pins 19.
  • Each curved arm 20 is connected at an intermediate point, through a pivot 22, to a curved lever 23 which is provided at its free end with a notch 24.
  • the lever 23 is guided in a transversely elongated eyelet formed by a strip 25 attached to the respective end member of the movable frame 5 and cooperates with a double lever 26 pivotally supported intermediate its ends on a fixed pivot 27.
  • a helical spring 28 acts upon one arm of the lever 26 to urge a nose 260 formed on the other arm of the lever 26 against the convexly curved edge of the curved lever 23, with a force sufficient to hold the curved lever 23 against a fixed peg 29.
  • a release lever 30 with two arms is used.
  • the release lever 30 is mounted on a vertical pivot 31 carried by the movable frame 5 and is provided at one end with a manually movable handle 32. By moving the handle 32 the other end of the release lever 30 acts upon the internal concavely curved edge of the curved lever 23, disengaging the notch 24 of the lever 23 from the peg 29.
  • the curved lever 23' rests with its concave edge against a reaction device constituted in this example by a roller 33.
  • the lever 23 has at its lower end a notch 24' in its convex edge: the double lever 26 has at one end a nose 26'a which engages in the notch 24' of the curved lever 23 in the overturned position of the back, and the lever 26' has at its other end .a handle 26'b which is manually oper ated to effect disengagement of the nose 26'a from the notch 24'.
  • the convertible bed-settee unit herein described is of simplified construction since the connection between the movable frame 5 and the fixed frame is effected at each end through a single lever with three arms and through the engagement of the rollers 10 in the guides 3 and 4.
  • the connection of the back 8 to the movable frame 5 is in turn effected through the curved lockable lever 23, 23' and the lever 26, 26'.
  • This makes it possible to reduce the overall height and thickness of the two end pieces 2, as compared with the arms of a conventional bed-settee unit, and the upper surfaces of the end pieces 2 are substantially coplanar with the mattress in the position use as bed.
  • the thickness of each end piece 2 can thus be used to support a pillow or cushion, so that the proper dimensions of the bed are maintained, whilst reducing to minimum the overall length of the unit.
  • the bed-settee unit according to this invention is convertible to a single bed, essentially in the manner described with reference to FIGS. 1 to 7.
  • the movable frame 5, which contains the resilient support of the mattress '7, extends longitudinally so that in the two modes of use respectively as a settee and as a bed the overall dimensions of the unit do not vary.
  • a shaped plate 35 is fitted to each lateral end of the movable frame 5.
  • An outwardly projecting longitudinally extending stub axle 10a is attached to each plate 35, the axles 10a carrying the respective flanged rollers 10 which are located be tween the two guides 3 and 4 in the two end sub-frames l of the fixed frame.
  • Each plate 35 is connected with the corresponding end sub-frame 1 by means of a respective three-armed lever 13, of which one of the arms, the longest, is connected by means of a pivot 12 to the plate 35, a second, shortest arm is connected by means of a pivot 14 to one comer of the sub-frame l and a third arm I5 is subject to the action of a tension spring 16 anchored to a support 17 on the subframe l.
  • the longest am of the three-armed lever 13' has a I projection 41 which is articulated by means of a pivot pin 40 to one end of an angle lever 39 the opposite end of which is releasably connected through a further pivot pin 38 to a second three-armed lever 37 which connects the plate 35, and therefore the movable frame 5, to the frame structure 21 of the back 8.
  • One of the arms 37a of the lever 37 is pivotally connected through a pivot pin 36 to the plate 35, a second arm 37b is connected rigidly to the back frame structure 21 of the back and a third arm 370 is pivotally connected through the pivot pin 38 to the angle lever 39.
  • the arrangement of the levers is such that the back 8 passes automatically from the erect position (FIG. 9) to an inverted position (FIG. 11) in which it is located beneath the seat 6 of the settee through the effect of the rotation imparted to the frame 5 in passing from the position of use as a settee (FIG. 9) to the position for use as a bed (FIG. 1 l and vice versa.
  • the back 8 in the inverted position (FIG. 11) the back 8 is locked with respect to the seat 6 and can move only when the movable frame 5 is brought back into the position for use as a settee.
  • each of the end sub-frames l of the fixed frame may be readily dismantled from the remaining parts of the unit, so as to reduce the overall dimensions and thereby facilitate packing and transport.
  • a double-bed unit can be produced as shown in FIGS. 12 to 15.
  • the movable frame 5 is articulated and is constituted by two portions S'a, 5'! and by intermediate portions 5c connected to the said two portions 5'0 and 5b by hinges 43 and 44; each frame portions S'a, 5b and 5'0 has a width which is substantially equal to that of the fixed frame.
  • an articulated closure element 45 which completes the closure of the other parts of the movable frame 5 in the contracted or folded-up position of use as a settee,
  • the hinging movement of the closure element 45 is limited by stay rods 46.
  • the closure element 45 carries a fixed retaining eye 51 adapted to cooperate with a hooked bolt 47 which is slidably mounted in a tubular guide 48 carried at the free end of the frame portion 5 b.
  • the bolt 47 is attached toan operating element 50 which is acted upon by a spring 49.
  • the hooked bolt 47 is engaged in the retaining eye 51: to effect disengagement the element 50 is manually operated so as to remove the hooked bolt 47 from the eye 51 and thereby permit opening of the articulated frame.
  • the overhanging parts of the frame 5 must be supported by legs to ensure that the bed is kept even.
  • Each of the legs 52 nearer the fixed frame is connected through a pivot pin 57 both to one end of the respective connecting rod 56 and to a fixed bracket 58 carried by the intermediate frame portion 5c of the articulated frame 5.
  • each leg 52 is bent to form an inclined appendix 52a which is articulated through a pivot 59 to one end of a second connecting link 60 of reduced length, the opposite end of the link 60 being articulated, through a pivot pin 61, to a bracket 61a carried by the second portion Sb of the articulated frame 5.
  • Each of the end legs 53 is connected at its upper end to the second end of the respective connecting rod 56 through a pivot pin 62. At its upper end each leg 53 is provided with a transverse lug 53a which is pivotally connected through a pivot pin 63 to a bracket 64 mounted near the free end of the frame portion 5b.
  • the articulated frame 5 is not provided with lateral plates of the type shown at 35 in FIGS. 8 to 11, since the pivots of the connecting levers are carried by single brackets attached, for example by welding, to one of the portions 5'a of the frame itself.
  • the two flanged rollers 10 are mounted on axles which are interconnected by a single tubular spar connected to the said frame portion 5a by means of suitable brackets or'the like (not shown).
  • FIGS. 12 to 15 can be used to obtain beds of the single type; in this case the length of the unit is reduced and in the folded position for daytime use, a lounger, rather than a settee, is formed.
  • a convertible bed-settee unit of the type comprising a fixed frame having two interconnected end portions and a movable frame, adapted to be rotated about a longitudinal axis and carrying on one face a seat and a back for use as a settee and on the other face a mattress support for use as a bed, wherein the improvement consists in that the unit further includes; two flanged freely rotatable rollers carried by the movable frame at opposite ends of a common longitudinal axis parallel to and displaced with respect to the median longitudinal axis of the movable frame; respective pairs of parallel guides along which said rollers move, said guides being carried by two ends of the fixed frame; respective three-armed levers connecting each end of the movable frame to the corresponding end of the fixed frame, each said three-armed lever having one arm which is articulated to the movable frame at the centre line of the latter, a second arm which is articulated to one end of the fixed frame and a third arm; a traction spring anchored to the respective
  • said movable frame comprises a plurality of articulated portions which when folded are adapted to enclose a mattress, said frame portions extending in the transverse direction when unfolded in the position for use as a bed and including retaining means for maintaining the articulated frame portions in the folded position, and including auxiliary support means for supporting overhanging parts of the frame in the open position of the latter.
  • auxiliary support means comprise two pairs of hinged legs and means for moving said legs automatically into supporting and retracted positions upon unfolding and folding respectively of the articulated frame.
