Definitions
- the present invention relates to a modular seating arrangement of a transformable seat, in particular for forming a short seat, a long seat and a full bed.
- the invention also covers the furnishing element obtained.
- a first problem is that of forcing the mattress to take the appropriate folding when passing from the sleeping position to the seat position.
- a second problem is that of the slats which slide in the telescopic uprights and whose ends are positioned in grooves of said amounts. End caps and traction links for the slats are provided, but these may have a tendency to position themselves crosswise during translational maneuvers, before tensioning the links, which is not satisfactory. In addition, it must be possible to secure the mattress to the chassis, at its end so that the latter remains secured to the chassis during the folding maneuvers, which is another problem.
- the feet are also a problem especially those at the end because they must not interfere with the maneuver while ensuring effective support in the lying position of this chassis.
- the present invention meets these constraints by an improved modular seating arrangement of a seat convertible into a bed.
- the modular seating arrangement of a convertible seat in particular for forming a short seat, a long seat and a full bed comprising a frame with pairs of telescopic uprights, slats arranged between these uprights surmounted by a mattress and means for connecting these slats to each other, is characterized in that it comprises means for securing the mattress to the free end of the chassis.
- a first part of these securing means is associated with the end cross member of the last pair of uprights and a part is associated with the mattress.
- the securing means comprise a tab made of rigid metal wire, bent in a U, situated in the plane of the seat, secured to a cross member at the end of the chassis and a sleeve secured to a cover of the mattress, said sleeve receiving said tab.
- the arrangement according to the invention also provides a sleeve for receiving the slats, itself comprising as many housings as slats as well as connection means at the ends.
- each housing has a length and a width substantially identical to that of a slat.
- each foot comprising a roller disposed in the corresponding upright, an axis of rotation passing through the lumen, an arm integral with this axis, a lug of support and blocking means.
- the locking means consist of a hook capable of cooperating with another of the pairs of uprights, this hook being equipped with elastic return means.
- the invention also covers the furnishing element comprising a quilt • with suitable connecting means for folding the side flaps so as to provide the dual function of seat covers and bedding duvet.
- FIG. 1 a perspective view of a chassis according to the prior art
- FIG. 2 a top view of this same chassis, according to the prior art
- FIG. 3 a detailed view of an upright of the chassis according to this prior art with a slat
- FIG. 4A a view of this chassis fitted with removable fixing means for the mattress according to the present invention
- FIG. 7A a view of means for guiding the slats of the bed base associated with said chassis
- FIG. 7B an alternative embodiment of the guide means of FIG. 7A, and - FIGS. 8A and 8B, a view of the two positions of a folding foot according to the present invention
- the chassis 10 shown comprises a seat
- the seat 12 is convertible and composed of pairs of uprights 16, 18 and 20, in this case three pairs.
- the uprights of each pair, arranged on the same side, are telescopic and sliding mounted one inside the other so as to allow the modification of the longitudinal dimensions of this seat.
- Spacers 26 ensure the rigidity and mechanical strength of said chassis. 28 feet complete this chassis. These feet are integral with the uprights so as to follow their movements during the different translational movements of the sliding parts.
- FIG 3 still relating to the prior art shows the advantage of having a slot 22 on the inner face of each upright since each slat, which is curved to ensure an elastic return movement, lengthens when the chassis supports a charge.
- the embodiment according to the present invention consists in providing means 32 for securing the mattress to the free end of the chassis.
- a first part of these means is associated with the cross member 34 at the end of the last pair 20 of uprights, in the form of a tab 36.
- this tab 36 is produced from a rigid metal wire, previously bent into a U, the ends of which are linked, for example by welding to said end cross member 32.
- the bottom of the U of the metal wire tab is oriented towards the backrest.
- the tab may comprise only two parallel rods.
- the mattress 38 is placed on the assembly and according to the invention, it is advantageously equipped with a cover 40 with a sleeve 42 which constitutes the other part of the securing means 32.
- a cover 40 with a sleeve 42 which constitutes the other part of the securing means 32.
- it is a pocket attached to the underside of the cover of this mattress.
- it should rather provide two sleeves.
- the choice of the density of the material constituting the mattress is also important since it must be sufficient to ensure the comfort of the bed and the seat without disturbing the folding during the passage of the seat of the sleeping position in seat position. It is advantageously a high density foam.
- the transformable seat has its seat in the sleeping position.
- the mattress 38 is in its cover 40 and the tab 36 is introduced into the sleeve 42.
- the cross-member 34 When the user pushes the cross-member 34, he pushes the uprights which penetrate into each other, shortening the length of the seat.
- the mattress 38 being secured to the end of the frame, over the entire first portion, the only solution for the mattress when shortening the seat is to bend as shown in Figure 5B.
- the mattress is positioned with two opposite curves 44, 46 forming an S.
- any variant of the securing means such as a plate in replacement of the U-shaped leg or with two rods, with pressures for fixing the cover to this plate is considered to be a technical equivalent.
- the mattress shown in FIG. 6 is provided with non-opening transverse slots 43, distributed in the folding zones in particular.
- the slots open on the upper surface and join on the lower surface allowing articulation and flexibility.
- FIG. 7A an embodiment of the links 30 between the slats is shown. The embodiment shown makes it possible to solve the problem of crossing these slats.
- This embodiment consists of a sheath 48 produced from a canvas of width substantially identical to that of the slats with housings 50 multiple of a length and a width such that they make it possible to contain in each of them. most of the corresponding slat.
- Each slat is thus kept substantially parallel to the previous one.
- the degree of angular freedom with respect to the uprights is reduced in all cases and prevents any blockage during deployment or folding of the seat.
- fasteners 52, 54 to secure the ends of this sheath on one side to the backrest / headboard 14 and on the other side to the cross member 34 for example.
- FIG. 7B an alternative embodiment of a sheath 48-1 has been shown which consists in providing buttonholes 55 to let the slats 24 pass.
- the slats 24 are positioned above / below along the transverse axis .
- the retractable feet 56 are integral with the uprights of the pair 20 of uprights.
- Each leg 56 comprises a roller 58 mounted in the corresponding upright, the axis 60 of rotation passing through the lumen 22 and an arm 62, integral with this axis 60.
- the arm 62 can thus pivot freely around this axis 60 and the roller can roll in the upright without being able to extract it, its diameter being greater than the width of the lumen 22.
- the arm also carries a support lug 64.
- Locking means 66 perform several functions.
- These locking means consist of a hook 68 able to cooperate with the pair
- a wheel 72 is attached to the end of the arm 62 for reasons of convenience of operation.
- the roller 58 can move in the upright and the foot is raised until its lug 64 comes into contact with the underside of the upright, allowing a bracing. g Conversely, when the seat is folded, the accumulation of slats repels the roller and forces the foot to rise and come to hook at the end of folding.
- the arrangement according to the present invention makes it possible to have a chassis that is perfectly functional and compatible with industrial production under the best technical and economic conditions.
- these two feet can make only one U-shaped entity for example.
