ABSTRACT:
The invention relates to a device for lying or sitting according to the generic part of the first independent claim. The inventive device comprises a mattress, a lath grid being flexible in the direction of its length and a springy support for the lath grid. If the device is to be applicable not only for lying but also for sitting it is usually narrower and comprises a back extending along its length.
From the publication EP-0243383, a device for lying is known which device is light and of a simple design and which all the same offers a high lying comfort even when used with a thin mattress only. This device for lying comprises a lath grid having a plurality of parallel laths extending perpendicular to the length of the device, which laths rest on at least two springy longitudinal beams. The laths and the springy longitudinal beams are connected to each other and kept in place relative to each other by means of a lath grid cloth. This lath grid cloth has substantially the rectangular form of the lying device and comprises means for fixing the laths, e.g. rows of lath pockets running along its longer edges, and tunnel-like sheaths for the springy beams. The lath grid cloth is dimensioned in such a way that it is tensioned perpendicular to its length by the laths positioned each in two opposite pockets. Lath grid cloth, laths and beams form together a light and still stable unit which is flexible in the direction of its length and can e.g. be rolled up. All the same the unit can easily be taken to pieces for cleaning purposes or if necessary for exchanging parts of it. For use, the cloth/lath/beam-unit is advantageously covered with an only thin mattress consisting e.g. of latex. For use, the device for lying is positioned directly on the floor or on a support structure or on the beams of a bed frame.
Publication DE-4114417 show a similar device for lying or sitting, which device comprises two lateral ribbons for fixing the laths in a lath grid.
The publication WO-96/28072 (exchangeable lath) deals in particular with specific embodiments of pocket rows for positioning laths. In the same publication sheaths for mattresses are described having integrated pocket rows. In such an embodiment the laths are fixed in pockets directly on the bottom side of the mattress and mattress an laths form a unit which is positioned on separate springy beams. This embodiment is particularly suitable for being used with fixed sheets which are positioned in a tensioned manner around the mattress/lath-unit.
The object of the invention is to improve, regarding ease of handling, the device for lying as shortly described above without though reducing its lying comfort and without rendering fabrication more complicated.
This object is achieved by the device for lying as defined by the independent claim.
The inventive device for lying which is used positioned directly on the floor or on a support frame or on the beams of a bed frame comprises the following parts: a mattress, a sheath for the mattress, a plurality of laths, a lath grid cloth with lath fixing means, e.g. lateral pocket rows, at least two springy longitudinal beams and possibly sheaths for the beams made of cloth. The lath grid cloth and the beam sheaths may be connected to each other in a permanent or detachable manner. The mattress sheath and the lath grid cloth are connected to each other in a detachable manner by detachable connection means such that the lengthwise flexible lath grid can be fixed to the bottom side of the mattress the laths being positioned between the mattress and the lath grid cloth. An important feature of the inventive device for lying is therefore the unit comprising lath grid and mattress which unit can be separated into its parts very easily and which unit is covered substantially on all its sides by cloth (mattress sheath and lath grid cloth).
