Sofa bed

The invention relates to a device on a sofa which can be converted into a bed 1 specified genus.

With one from the German disclosure document 3D OD 957 known sofa bed of the type described above, from which the invention is based, the sofa seat by means of two four-bar jointed on the sofa frame sides "

Chains from the seat position / pivoted upwards at the front ₉ and the two mattress parts can only be pivoted out of the frame frame that has been pulled forward after the sofa seat has been pivoted upwards.

However, that sofa bed known from the aforementioned German patent application is Bowohl in terms of manufacture and assembly ala still relatively complex in terms of handling for converting the sofa bed.

The object of the invention is to provide a device of the type specified in the preamble of claim 1 in this respect. to improve far that at least while maintaining the smallest possible sofa frame depth with the largest possible

Seat depth with simple means a simplification of the Production, assembly and manageability achievable is.

The; The solution to this problem is characterized by the fact that the sofa seat is rigidly attached to the sofa frame that telescopic rod guides are also provided and that the adjustment stroke of the frame supporting the mattress parts is greater than the depth of the sofa.

An advantageous embodiment of the subject matter described above is characterized for this by the fact that the mattress foot part on the frame frame can be pivoted upwards and forwards is articulated and that the mattress middle part on the mattress base is designed to be supported so that it can be folded back on the rack frame.

A variant that may be preferred is characterized by that the mattress middle section on the GG frame is hinged at the top and at the rear, and that the ■ Mattress foot section is hinged so that it can be folded forward.

Compared to the prior art, this eliminates the need for the relatively complex and expensive four-link chains for articulating the sofa seat on the sofa frame. Nevertheless, the sofa bed can be comfortable

Under certain circumstances, skids can also be provided instead of the rollers 6.

A two-part mattress is arranged in the frame frame k.

Both mattress parts 7 and B each have approximately the same width and approximately the same length as the sofa seat and, with the inclusion of the sofa seat (FIGS. K and 8), complement each other to form a bed-length reclining surface.

In FIGS. 1 to k , the mattress foot part B is articulated by means of two four-bar chains 9 in the frame frame k so that it can be pivoted up and out and carries an adjustable footrest 1D on its underside.

The four-link chains 9 are assigned springs 11, which on the one hand erect the four-link chain swing arms support and on the other hand hold the four-bar chains in their end positions so that they can be overcome.

The mattress middle part 7 is hinged to the mattress base part B by means of two four-bar chains 12 so that it can be folded backwards, provided that the frame frame k is pulled out to the front and
