- a mattress of this kind has no rigid members, except at its periphery, and this ensures excellent comfort.
- the mattress is supported at its central portion by two rows of coiled springs 46 and 47, these rows being parallel to the cross-members 3% and 40.
- the row of springs 46 is arranged slightly in front of the pivots 32, whilst the other row 47 is arranged slightly to the rear of these pivots.
- the springs 46 are fixed under the points at which a strip 42 crosses the strips 44, and are supported on a horizontal bar 48 parallel to the cross-mernbers 39 and 40.
- the bar 48 is spaced apart from the mattress and has the shape of a cradle, being fixed to the bars 10.
- the same arrangement is provided for the other row of springs 47 which rest on a cradle 49 fixed to the bars 11.

- a removable bed-head 54 is provided (see Fig. 4) to be arranged along the bars Ml and 11 at either one or the other end of the bed.
- This bed-head d consists of a flat plate of the same length approximately as the sum of the lengths of the bars it? and Ill. The height of the plate is chosen to be greater than the thickness of the mattress 55 so that the plate can form a stop for the pillows (not shown).
- the plate 54 is provided with a notched portion cut in the central part of its lower edge the notch being arranged to surround the axes 31, 12 and 25.
- a shaft end 57 is fixed roughly in the centre of the plate 54- and is intended to receive the slot 37 in the crank-arm 36.

- the pivot 57 is so arranged that this operation can be carried out from either the one end of the bed or the other.
- the crank-arm 36 When it is desired to change over to the divan position, it is only necessary to unhook the crank-arm 36 and remove the plate 54.
- the latter can, for example, be put away in the drawer 53.
- the stop 38 In the divan position, the stop 38 is so arranged that the bars 1d are slightly inclined downwards and towards the rear so that the front part of the mattress which forms the seat slopes back towards the rear, which gives a very comfortable position.
- the elastic support of the seat itself is formed by the stretched strips 50 and the strips 42, whilst the strips 44 and 42 constitute the elastic support of the back.
- Movable arm-rests 60 are preferably provided in such manner as to be fitted in the divan position, while they are removed and put away in the drawer 53 in the bed position.
- Each arm-rest 60 comprises a forkshaped extremity 61 which engages round a pin 62 on the lever 27.
- a pin 63 is fixed on the armrest, and is intended to be engaged in an elongated slot 64 in the bar 11.
- a divan-bed comprising in combination a seat element and a back element, said elements being adjacent along an intermediate horizontal axis and pivoted to each other along said axis, said elements defining themselves the whole bed surface when the back element is lowered around said axis to form a horizontal extension of said seat element, a first supporting means for supporting the seat element, said first supporting means forming with said seat element a hinged leverage quadrilateral assembly, a second supporting meansfor supporting the back element, and connecting means having two members hinged with respect to each other and hinged to said assembly and to said second supporting means.
- each of said supporting means forms with the element supported thereby a hinged leverage quadrilateral assembly having two levers respectively pivoted on the corresponding element and extending downwardly therefrom in any position of the divan-bed and a third lever, the two ends of which are pivoted on the said first two levers respectively.
- a divan-bed comprising in combination a seat element, a back element, said elements being pivoted to each other, a first supporting means for said seat element, said first supporting means forming with said seat element a hinged leverage quadrilateral assembly, bearing means for grounding a front portion of said assembly, a second supporting means for said back element, means connecting a rear portion of said assembly to said second supporting means, said second supporting means having two levers, one of said levers being a rear bearing in the divan position and a central bearing in the bed position, and the other lever forming a rear bearing only in the bed position.
- a divan-bed comprising a seat element and a back element, said elements being pivoted to each other and movable between a bed position and a divan position, a member carried by said back element and movable to a lower plane in the bed position than in the divan position, a main lattice mattress common to both elements and connected to the periphery thereof, and an additional auxiliary lattice mattress for said element, said additional auxiliary lattice mattress being connected to the front end of said seat element and to said member and being operative in the divan position and inoperative in the bed position.
- a divan-bed comprising a seat element, a back element, said elements being pivoted to each other, a first supporting means for seat element, said first supporting means forming with said seat element a hinged leverage assembly adjustable between a high level seat position and a low level seat position, bearing means for grounding a front portion of said assembly, a second supporting means for said back element, means connecting a rear portionof said assembly to said second support- References Cited in the file of this patent UNITED STATES PATENTS Crouch, et a1.
