Definitions
- sofas convertible into beds contain into their structure a metallic frame which has a articulated folding structure, including a fixed frame for the support to which are connected some mobile frames consecutively hinged between themselves.
- the mobile frames are folded one on another and inserted inside of the support fixed frame; in order to form the bed, the mobile frames come out the fixed frame by a rotary and translatory movement until they line up between themselves.
- the back is mounted directly on the most outward mobile frame instead of on the structure of the sofa.
- pantographic lever which causes the coming out of the frames themselves in order to bring them in a raised and leading position in relation to it.
- the sofas having a folding and articulated structure there are furthermore some devices permitting to synchronise between themselves the vertical translatory movement and the rotary one of the distension of the mobile frames in order to bring them with only one operation from the position of the sofa into the position of a bed and vice versa.
- some devices permitting to synchronise between themselves the vertical translatory movement and the rotary one of the distension of the mobile frames in order to bring them with only one operation from the position of the sofa into the position of a bed and vice versa.
- foreseen tricks which permit to obtain a stable sofa bed, either in bed position, either in sofa position, or closed, without the use of any locking device. That said, we can note that the sofa beds usually sold which use the above described techniques show some disadvantages, like: a) Impossibility to obtain a bed with a sufficient length in order to permit to a person which is higher than the medium to have a comfortable rest, without increasing for that the encumbrance of the sofa. b) Impossibility for the fixed frame
- Main end of the invention is to eliminate all said disadvantages of the sofa bed having an articulated and folding structure.
- this invention solves the problem of getting a bed suitable also to people higher than the medium, without increasing the encumbrance of the fixed frame for the support and in order to hide, with a pleasant look, the double function sofa / bed.
- the invention solves the problem of furnishing a mechanism able to synchronise contemporarily, and with adding any operation, the movements that the framework has to do to become a bed.
- fig. 1 a side view of the articulated frame in a sofa function
- fig. 2 a side view of the frame during the first phase of the transformation into bed
- fig. 3 a side view of the frame in an intermediary position of opening
- fig. 4 a side view of the frame in a successive phase transformation
- fig. 5 a view of the frame when changed in a bed
- fig. 6 the blocking device of the auxiliary mobile frame in the releasing phase
- the sofa bed is made of a fixed frame 1 with rectangular plan, in which is inserted all the framework constituting the bed, there including the mattress and a known type of pantographic structure, already used in the construction of the sofa beds, which supports a mobile frame 2.
- a first auxiliary mobile frame 3 having a U-shaped section, to which is hinged a second auxiliary mobile frame 4 connected in turn to a third auxiliary mobile frame 5, which, when they are laying, are forming the horizontal framework supporting the bed mattress.
- the third auxiliary mobile frame 5 is integral with legs 6 and orthogonal to them, which support the extremity of the bed not supported by the pantographic structure 18.
- the pantographic structure lifting it, causes the coming out of mobile frame 2 when, to form the bed, the first auxiliary mobile frame 3 is made rotate.
- the rotation of the first auxiliary mobile frame 3 is caused by the second auxiliary mobile frame 4 hinged in 19 to the first mobile frame 3; the rotation of frame 4 is caused in turn by the third mobile frame 5, by the compound lever 24 and 22 hinged with pin 17 at the first auxiliary frame 3 and at lever 16 which transmits its movement to little wheel 11 running in eyelet 10.
- Rods 24, 22, 16, 13 and 12 constitute the compound lever which synchronise the movements of the frames constituting the bed.
- the interconnection rod 20 transmits the movement of the auxiliary frame 4 to the first mobile frame 2 and vice-versa; the little arm of lever 20 keeps in fact the second mobile frame 4 from rotating around the extremity 19 of the first mobile frame without transmitting movement to the first mobile frame 2.
- lever 24 is welded to the third auxiliary mobile frame 5; the supporting leg
- the first auxiliary mobile frame 3 acts as an interconnection element between the second auxiliary 4 and the principal mobile frame 2.
- the second auxiliary mobile frame 4 is blocked to the fixed support frame 1 by the blocking device illustrated in details in fig. 6 and 7.
- Said device is constituted by a hook 33 hinged in point 40 and reactioned by a spring 35.
- the hook is driven by the little lever 36 connected to a flexible tie-rod 37, provided at its extremity with a pommel 38.
- the tie-rod 37 runs through the hole of a L shaped plate 42 which blocked it when the hook is in closing position.
- the lever 22 which causes the blocking of the second auxiliary mobile frame 4 is provided with a pin 32 which goes to thread itself into the fork 34 when the second mobile frame 4 is folded to form the sofa: by the hook 33, the pin 32 remains blocked into the fork 34.
