SOFABETT

The invention relates to a sofa bed with a rigid, U-shaped base frame made up of a back part made up of two side parts and with an insert made of upholstered elements and telescopic, Pull-out guides covered by mutually displaceable ferrous wood strips.

There are known sofa beds that can be converted into a bed by means of a so-called folding bed fitting with an internal mattress, which by folding down the backrest with the seat cushion form a lying surface, which have multi-part, extendable frames and separate mattress covers and which are made by pulling out bed box trolleys and folding them down the seat cushions form a bed. All these known sofa beds have the disadvantage that they are expensive and complicated in their construction, bulky in their appearance and / or difficult to use. In addition, the lying areas usually have a comparatively small distance from the floor, which makes it impossible for older or disabled people to use them.

The object of the present invention is therefore to provide a sofa bed to create that is comparatively simple in construction and operation and also has a lying area has a comparatively large ground clearance. The solution to this problem is, based on the sofa bed mentioned at the beginning, in the Main claim characterized.

According to the invention, the insert, which contains the pull-out elements forming the lying surface, is hinged to the base frame in such a way that that he has a lowered position for the use of the sofa as a seat and a raised position for the use of the sofa as a bed Position. The pull-out elements are then used to create the lying surface from the raised position Insert pulled out so that the desired bed height is above the

Floor is guaranteed, with fold-out foot elements providing support.

In the drawing, an embodiment of the sofa bed according to the invention is shown; show it:

Fig. 1 the sofa bed in side view, partially in section, namely in the lying state,

Fig. 2 is a sketch of the sofa bed in side view, partially in section and

Fig. 3 is a perspective sketch of the sofa bed for explaining the transition from ^un seat in the lying state.

According to the drawing, the sofa bed has an essentially U-shaped base frame made up of a back part 10 and two side parts 11 (FIG. 4), into which a multi-part insert, designated as a whole by 12 (FIG. 3), is inserted. The insert 12 has a carrier plate 13 on which a lower foam pad 14 is firmly seated, and an upper | Foam pad 16 GUESS with the lower foam cushion 14 * _f-connected here how best seen in Figures 1 and 2. FIG. Two lateral running strips protrude downward from the carrier plate 13, which are designed like a frame and together with the carrier plate 13 form a box that is open at the bottom, front and rear. In the interior of this "box" a pull-out part is housed, which consists of pull-out guides 18 arranged on the running strips 17 and spring wood strips connected to one another by a fabric 19, a vertical end panel 21 being attached to the free end of this spring wood frame 18, 19, 20. On the underside of the spring wood frame 18, 19, 20, two hinged foot stirrups 22 are articulated adjacent to the end panel 21.

Lever arms 23 are articulated on both sides of the insert 12 at the front and angle levers 24 at the rear. The other ends of the lever arms 23 are hinged to horizontal tabs 25 which are rigidly attached to the inside of the side parts 11. Neighboring the

rear end of the tabs 25 are rigidly attached to this vertical arms 26, at the upper end of which the angle levers 24 are hinged are. This lever linkage has two end positions, namely the raised end position shown in Figure 1 and the in Figure 2 indicated lowered end position, with usual, not shown in the drawing stops and / or locks are provided for the two end positions. A coil spring 27 is hung on the one hand on the fastening strap 25 and on the other hand on the angle lever 24 and serves to facilitate the transfer of the insert 12 from the lowered end position to the raised end position.

Around the insert 12 from the raised end position shown in FIG. 1 (lying position) into the lowered position shown in FIG To transfer the end position (sitting position), the insert 12 is initially moved forward to a limited extent (to the right in FIG. 1), with the result that the angle lever 24 around its point of articulation on the arm 26 and the lever arm 23 around its point of articulation on the fastening strap 25 can be pivoted clockwise, the rear end of the insert 12 (left end in Figure 1) slightly tilts down. As soon as a certain pivoting angle of the levers 23 and 26 is reached, the lever arm 23 reverses its pivoting direction around, so pivots counterclockwise, whereas the angle lever 26 continues its pivoting movement clockwise, with the result that the insert 12 sinks obliquely backwards (to the left in FIG. 1) until the one shown in FIG. 2 is lowered End position {sitting position) is reached. The process of lifting the insert 12 from the lowered end position of Figure 2 in the raised end position of Figure 1 takes place in the reverse manner, the spring 27 facilitating the lifting.

In the sitting position shown in FIG. 2, the insert 12 is in its lowered end position, with the foam cushions 14 and 16 lie on top of one another on the carrier plate 13 and are covered by a loosely placed seat cushion 28. The pull-out elements, namely the pull-out guides 18 and the spring wood

afford 20 are between the tracks 17 in the space below the support plate 13 housed. Should now the seat and When the sofa bed is moved into the reclining position, the insert 12 is first swiveled up as a whole, as shown in FIG 3 is indicated and has already been explained in detail above, until the raised end position is reached. The The cover 21 is pulled out towards the front, with the result that the pull-out guides 18 and those connected by the fabric 19 are also connected to one another Spring wooden slats 20 are pulled out and thus a Federhoiz reclining frame is created, which is then swiveled away by swiveling the foot stirrups 22 is supported downwards. This is the one shown in Figure 4 " position reached. The seat cushion 28 is now placed as a foot part on the base frame and the upper foam cushion 16 is folded over so 'it ate the space between the bottom. Foam pad 14 and foam pad 28 fills. That’s the Lying position shown in Figure 1 is reached. It is essential that the bed surface is at a considerable height above the Ground is located, for example in so-called "senior height".

The return of the furniture from the lying position of Figure 1 to the sitting position of Figure 2 takes place in the reverse order of the processes just described.

Of course, the invention can experience numerous modifications, in particular with regard to the structural design of the extendable Slatted frame, instead of the connecting fabric, springs can also be used, and the swivel mechanism for the Mission 12 concerns. It is essential, however, that the insert 12 is brought into a higher position and the. undressed Lying surface is supported by foot elements.
