Definitions

• the invention relates to a chair, which is convertible into a bed, with a frame and at least one retractable into the frame and extendable from this car. Furthermore, the subject of the invention is a coating for the lying surface of such a piece of furniture.
• An essential feature of the invention is that the frame and the carriage or cars have as a support for seat or couch pad in Ausziehraum the car (the carriage) running, one-sided fixed slats, wherein the slats have such a distance from each other that the slats of the car (carriage) are in the retracted state of the car (the car) between the slats of the frame.
• the slats of the frame are on the rear side of the furniture on a resilient crossbar, which is provided on both sides with rollers which are guided in guides which rise to the front, so that when inserted slats of the frame ( Sitting position) these run obliquely downwards, with extended slats (lying position) they lie horizontally.
• the guides are formed by deformed flat iron, each forming a receiving pocket for the roles in the sitting position and in the lying position.
• High quality beds today have two mattresses, a harder bottom and a softer top.
• the upper mattress is also often called the "comfort mattress.”
• the upper softer mattress provides support for the body in the sleeping position a larger area. This combination of hard and soft is considered by most experts to be the ideal solution.
• the invention has therefore set itself the goal of creating a coating that is easier to handle than before. This is achieved by virtue of the fact that the soft layer has an elasticity which counteracts curling, so that after rolling up the sheet, the layer automatically rolls over the lying surface.
• the role of a coating according to the invention is e.g. held together by a tape or the like and rolls after opening the tape automatically along with the sheet and lies down on the bed.
• the sheet can be connected by a Velcro fastener, snaps or similar easy to be solved connecting means with the soft layer.
• the soft layer is generally composed of two materials, namely a fibrous material at the top and a foam or rubber or polyether at the bottom.
• Foam or the like which automatically roll up, are already known. These documents are laid on the ground, for example, when camping, they are however not connected to a sheet. Coating a bed with a sheet would therefore not be facilitated with such documents.
• FIG. 1 is a plan view of a furniture according to Invention in the lying position and with removed pads.
• Fig. 2 is a side view, partially in section, of the furniture of Fig. 1, wherein the
• a chair convertible into a bed has a frame 1, a first carriage 2 and a second carriage 3.
• the frame 1 has a fixed frame part with lateral metallic supports 4 and legs 5 and 6 supported on the floor.
• a movable frame member has on resilient cross beams 8 and 9 resting slats 10 which are spaced from each other.
• the carriages 2 and 3 have slats 10a and 10b, which rest on corresponding resilient transverse slats, which are supported by legs on the ground.
• Fig. 3 is shown as an example that the one bar 10 b of the carriage 3 is connected to an angle 11 and is supported on a crossbar 12 which is connected to a leg 13.
• the slats 10, 10a and 10b each have such a distance from each other that the car 2 and 3 can be pushed into each other and in the frame l, in which case all the slats 10, 10a and 10b are adjacent , When you take off the car 3, the angle 11 take the car 2.
• the crossbar 9 of the frame 1 is provided with rollers 15 on both sides via roller carriers 14. These rollers 15 roll on flat iron 16, which have two receiving pockets 17 and 18.
• the receiving pockets 17 hold the slats 10 in the horizontal position, the other Aufhahmetaschen 18 allow a seat incline.
• the flat bars 16 are welded to the legs 6 and a rear flat iron 19.
• FIG. 5 is in plan view and enlarged, in Fig. 6 in a corresponding side view, illustrates the slat guide.
• an inserted batten 10a is shown on the left and the extended batten 10a on the right and a batten 10b on the far right.
• the slats 10 have at their ends stops 20 which cooperate with stops 21 of the slats 10a during insertion and removal of the corresponding car.
• stops 21 press on the stops 20 and when pulling the stops 21 pull on the arranged at the other end of the slats 10 stops 20, the movable part of the frame 1 in the position shown in FIGS. 1 and FIG. So that the free ends of the slats 10a and 10b are lifted when inserting the carriages 2 and 3 over the respective resilient crossbar 9, 12, lifting parts 22 are arranged on the slats.
• a furniture according to the invention is shown in the sitting position, which has only one carriage 2. Accordingly, in the sitting position only two pads 23, 24 are stacked.
• the furniture according to FIG. 8 essentially corresponds to the furniture according to FIGS. 1 and 2 with two carriages and three cushions 23, 24, 25.
• a rolled roll mattress 26 is used as the backrest, as described below.
• the pad 23 is each provided with a bead 27 which covers the upper part of the frame.
• a mattress 32 is placed on a bed frame 31.
• the bed frame 31 is provided with a bed head 33, which has a cavity 34.
• This cavity 34 is closed at the front by a padded lid (not shown).
• a coating 26 On the mattress 32 is a coating 26, which has a soft layer 36 and a sheet 37.
• the sheet 37 is connected to the soft layer 36 by means of a hook-and-loop fastener 38.
• the soft layer 36 is made of a material that is elastic enough to be able to automatically roll up a roll made of a soft layer 36 and a sheet 37.
• a role coating 26
• a sheet 37 is shown just when rolling up, which is illustrated by the registered arrow.
• a tension cloth 39 is arranged below the soft layer 36, which is rolled up with.
• This tension cloth 39 consists of a longitudinally substantially inelastic tissue, for. B. a Drell.
• the arrangement of such an inelastic Tension cloth 39 causes the soft layer 36 to be prevented from curling in and after, due to its elasticity, from enlarging its circumference.
• the winding and unwinding of the cover 26 is facilitated by a rod 40 which is connected to the end of the cover 26 to be rolled. As can be seen in FIG. 10, this rod 40 is connected to the cover 26 by means of a fabric strip 41.
• the tension sheet 39 'underlying the soft layer 36 is formed by the sheet 37' wrapped around the soft layer 36.
• Fig. 9 is also indicated that in the coating 26, a lying on the sheet 37 ceiling 42 and a bedding can be rolled.
• the ceiling 42 is only halfway through.
• the entire later roll 26 (layer 36, sheet 37 and blanket 42) is made of very soft materials. Pressing on the roll during curling and through the stiff bar and the inelastic outside forces the material to less than one third of its original volume.
• the roll can be used as a backrest, as shown in Figs.
• the cover (roller) 26 When rolled up, the cover (roller) 26 can be accommodated in the cavity 34 of a bed head.
• a plate may be provided against which the roller 26 is rolled.
• Velcro then the roller 26 can be kept curled on the plate.
• the space for the roller 26 behind a backrest normally has no round shape.
• the cavity in the backrest is usually higher than the roller and widens conically downwards.
• the roller is still soft enough to fit into the existing cavity.
• the trolley 3 could be equipped with only one plate, in particular MDF, instead of slats. It would then result in a smaller distance between the slats of the frame 1 and the carriage 2. If the carriage 3 were omitted instead of a longitudinal sleeper a cross-sleepers would arise, which is readily possible within the scope of the invention.
