— 3 —·■■·· ·· ·· ·· ·· Description

The invention described here characterizes a device for the lying down stay of persons (shelter beds), which are preferably used for rooms of structural civil defense and disaster protection.

In disaster or civil protection situations, where it is important to provide temporary or long-term accommodation for a large number of people in a confined space, bed designs are required that must meet special requirements. When not in use, they must be able to be stored in a confined space. They must be able to be set up quickly, safely and reliably, even by untrained personnel, and they must function flawlessly and safely when needed.

A large number of shelter beds are known to date. The state of the art is, on the one hand, that complete frames are manufactured into which the finished bed frames are mortised. Another system is that a large number of different rods are brought together at nodes and connected to one another using screws. Another principle is the mortising of struts in pre-punched hole rings which are in turn welded onto round supports. A system that has been known for a long time is the tensioning of chains between the floor plate and the ceiling; ready-made bed frames with the appropriate covering are hung onto the chain links using snap hooks. Another system is: tensioning pre-steel supports between the floor plate and the ceiling; in this system, beds are attached or hung onto this main strut.

There are significant points of criticism regarding this state of the art. Firstly, the bed frames are very bulky when stored "in one piece". They contradict the peacetime requirement of minimal storage. Secondly, the systems known from the state of the art are complicated to assemble. They require a lot of personnel and a lot of detailed work. This is especially true for joint connections that are fastened using screws and nuts. A third point of criticism is that the sometimes complicated manufacture of, for example ,

It does not seem possible to economically supply shelters with shelter beds using perforated rings in conjunction with egg-shaped connections. Another point of criticism is that beds that are attached to the floor are fundamentally based on unstable static conditions.

The new invention is therefore based on the task of developing shelter beds using commercially available and therefore inexpensive mass-produced goods that take up little space during storage, are immediately ready for use when set up even by untrained personnel, and that meet the required requirements when occupied.

According to the invention described here, guide rails (9) are already concreted into the ceiling during the construction phase.

The shelter beds consist of a square tube (�Lgr;), which has a hammer head screw suitable for this guide rail at its upper end.

At the height of the bed layers, short pieces of another square tube (6) are welded onto the square tube (4), so that 4 triangles of equal size are created in the overlapping area. A square steel tube can have several of these node formations.

The side and/or head struts (5) are designed in such a way that angle iron pieces (2) are welded to a welded bracket (7), each of which fills half of the triangles described above. The interlocking effect, in conjunction with the height of the struts or the insertion path of the steel pieces, creates a spatial, stable connection that is suitable for transferring the loads in three dimensions when occupied.

The creation of double beds is achieved by using cross braces, for example, which are preferably inserted into guide tubes using round iron.

It goes without saying that the bed linen must be inserted before the struts are inserted.

For higher loads, it is intended to use transverse stiffening

exercises.

The advantage of this solution is that a physically stable equilibrium is achieved by suspending it from the ceiling. Another advantage is that there are no protruding screws, nuts, tenon joints, etc. that pose a risk of injury.

Another significant advantage is that these spatially stable nodes can only be reached by plugging. In the storage ^case , all struts are stored in a very small space. Because there ^are no identical

are required, the possibility of cleaning the room without the otherwise annoying multitude of supports is optimally ensured.

It also goes without saying that this knot formation is suitable for, for example, catching knots (3) or the like. The attached figures represent a preferred embodiment of the invention. The reference numerals in the text ¹ correspond to the designations in the figures.
