DESCRIPTION:

BRIEF SUMMARY
The invention concerns a convertible chair-bed for indoor and outdoor use, whose elements consist of frames connected by joints and which may be brought from chair into bed position and vice versa by changing their position relative to each other.
It is known that there are a number of folding chairs for comfortable sitting and whose sitting position is adjustable, but not to the extent that the normal sitting position is turned into a fully horizontal reclining position.
There are also various pool lounges with a horizontal reclining surface and adjustable head and leg parts which, however, cannot be adjusted to the extent that a comfortable sitting position is obtained.
This is primarily a consequence of the seat height being too low.
Although a chair-bed is known from DE-A 34 17 283 which enables a normal sitting and reclining position, it is unsuitable for simple use as a beach or pool lounge because of the complicated mechanics, the many frame parts connected by joints, and particularly because of its heavy weight. Because of the many joints and frame parts, jamming while changing positions cannot be ruled out. In particular, this chair-bed cannot be folded completely flat for transport, for example, in a car trunk, and no intermediate positions are possible.
The invention has the objective of creating a chair-bed of the type mentioned which permits comfortable sitting as well as reclining. The chair-bed should also be easy to set up. Finally, it should be possible to fold it flat and to transport it easily.
The task is solved according to the invention through the characteristics of Claim 1. Useful types of the invention are reflected in the secondary claims.
The chair-bed according to the invention is easily set up and adjusted between sitting and completely horizontal reclining positions. This may be considered altogether amazing due to its rather simple construction since the customary pieces of furniture which are adjustable from sitting to reclining positions either have a very complicated and excessive construction making them hard to handle, or the adaptation of a chair to a completely horizontal lounge was unthinkable.
Other advantages, details and characteristics of the invention originate from the examples shown in more detail in the following drawings. Shown are in detail:
FIG. 1: the kinematics of a primary example of a chair-bed based on the invention in its folded state (schematic lateral view);
FIG. 2: schematic lateral view according to FIG. 1 of the chair-bed based on the invention in its unfolded state for the sitting position;
FIG. 3: another portrayal of the example according to FIGS. 1 and 2 in the schematic lateral view set up in the reclining position;
FIG. 4: a more detailed portrayal of the folded chair-bed in the lateral view;
FIG. 5: the chair-bed in the lateral view in the sitting position;
FIG. 6: condition of the chair-bed in the reclining position;
FIG. 7: another example of the chair-bed in the lateral view;
FIG. 8: the chair-bed according to FIG. 7 in the sitting position (lateral view);
FIG. 9: the chair-bed according to FIGS. 7 and 8 in the reclining position (lateral view);
FIG. 10: lateral view of another example in the sitting position;
FIG. 11: the chair-bed according to FIG. 10 in the reclining position (lateral view);
FIG. 12: lateral view of the folded chair-bed according to FIGS. 10 and 11;
FIG. 13: another portrayal of an example in the sitting position;
FIG. 14: the chair-bed shown in FIG. 13 in the horizontal reclining position (lateral view);
FIG. 15: lateral view of the folded chair-bed according to the last example .
FIGS. 1 to 3 show in a simplified drawing the lateral view of the change from folded chair-bed to chair, and then to lounge.
Here the chair-bed consists of front and back supports 1 and 2 i.e., first and second supports 1 and 2, which serve simultaneously as seat and back frame supports 1' and 2', respectively, and are connected to each other via an upper or first joint 3, a sitting and reclining surface 4 which in the shown example has fo
