Definitions

• the invention relates to a collapsible couch and / or seating furniture according to the preamble of claim 1.
• Sun loungers have always been one of the most popular sun loungers for relaxing and sunbathing, not only on meadows, on lakes or beach facilities, but even when skiing, where sunrays can often be hired in front of huts or made available for general use.
• the deckchairs can be easily set up and folded up. Although the storage space is relatively small, they are less suitable for transport, since the overall length is retained when the deck chair is folded.
• Loungers are also known which have a head part which can be adjusted at different heights and which generally have 3 to 4 U-shaped foldable low legs.
• the three-section couch When collapsing, the three-section couch, for example in the longitudinal direction, can be collapsed about transverse axes in such a way that a foot section, a central section and a head part come to lie one above the other and are folded together in a Z-shape in side view.
• the dimensions of the bed In plan view, the dimensions of the bed can be reduced to a third, but the thickness the bed then increases about three times.
• Such couches can be accommodated in the trunk relatively easily, but as couches that are mobile and require little storage space and are always easy to carry, these couches are also poorly suited.

• the lounger according to the invention can be carried along at any time without problems, even in a backpack when hiking, skiing, walking or even walking on the beach
• the bed according to the invention is characterized in that the longitudinal frame parts consist of a plurality of levers which can each be pivoted relative to one another, the pivoting range of which in the opening position is limited by a stop.
• the tensioned material web keeps the pivoted levers in the open position biased in the direction of the stop, thereby ensuring self-alignment and fixation. To fold the swivel levers only have to be flipped in the opposite direction.
• a deck chair can easily be folded into a small package of, for example, about 20 to 25 cm in height, the thickness of the package essentially being only the thickness the pivot lever corresponds to a few cm.

• the pivot levers 5 can each be pivoted about a transverse axis 11 to an adjacent pivot lever 5. In the open position, a subsequent swiveling lever 5 can be swiveled to its adjacent preceding one up to a stop 13. It can be seen in particular from FIGS. 5a and 5b that for this purpose each pivot lever 5 has an axle stub 15 with a shoulder or ring 17 projecting slightly at the free end beyond the outside diameter of the axle stub 15, which shoulder is inserted in a suitable manner by means of a pivot or in each pivot lever 5 trained axis bore 19 can be inserted.

This is because when the pivot lever is folded over, the distance between the upper and lower cross strut 9 holding the material web initially becomes somewhat larger, if the pivot lever is 180 ° extended from the preceding pivot lever. As soon as one pair of swivel levers is turned over, the next can be turned over. In other words, the length of the material web 7 is not so long that the side frame parts 3 and thus all the swivel levers 5 can be aligned together in a 180 ° extension.

• the upper and lower cross strut are designed telescopically in the exemplary embodiment shown. Due to the different lengths of the cross struts, the lower, longer cross strut is formed in three parts, so that the telescopic outer shell parts in each case can be telescopically pushed onto a thinner rod member located therebetween and thus pushed together.
• the upper cross strut in the embodiment shown is of five members.
• the material web 7 lies in a side view of the reclining furniture 1 above the longitudinal frame parts 3, i. H . above the swivel lever 5.

Otherwise the swivel levers would tip over in the opposite direction and the deck chair would collapse.
• the transverse fastening line 9 ' only generates 5 pretensioning forces in the partial direction 3' on the associated pivoting lever 5 in the direction of the stop when it is inserted into the material web. If necessary, further transverse struts 9 provided, on which the material web itself is not supported but instead runs at a distance above it, do not change the kinematics.
