Shaped bodies that can be cut with pointed objects 05

The invention relates to a device that can be equipped with pointed objects such as needles, wires, branches or the like,

these firm but removable shaped bodies that serve as a base or base for plant, flower, grave or similar arrangements, whereby the material forming the body has a low specific weight and gives it a shape and shape-retaining surface that is resistant to surface pressure or tensile stress"

Known molded parts of this type are made of rigid foams such as polystyrene (PS) or polyurethane (PU). Such plastic parts are used as supports or base or arrangement bodies for wreaths, so-called Romans, flower arrangements, grave arrangements, grave toppings, decorative arrangements or the like. The supports have the shape of geometric bodies such as cuboids, diamonds, rhombuses, crosses, hearts, rings, spheres or parts thereof. Parts to be attached such as flowers, branches, stems, twigs, wires, threads, nets, mats, decorative items, advertising announcements and much more can easily be fixed, arranged and/or grouped on the molded body, if necessary directly 0 and/or indirectly with e.g. single or double needles , the latter e.g. in a U-shape as so-called adhesive pins, wires or the like, by inserting the parts or the means holding them into the molded body with slight pressure. The well-known elastic body made of plastic that can be fitted with needles is also

its porosity, but its solid exterior! Form as a to a certain degree flexible, shock-absorbing packaging material and/or insulating element, which is particularly suitable as a heat-insulating body, used

Nowadays, the above-mentioned molded parts made of rigid foam are produced as waste in considerable quantities* Z ₁ B4 a considerable volume of waste is already generated each year as a result of the arrangements for graves provided with rigid foam bases* As plastics such as the PS or PU rigid foam materials used to form molded parts can only be disposed of and/or deposited in a way that is harmful to the environment and must be disposed of ⁱⁿ particular in special landfills, with incineration sometimes also being problematic due to toxic emissions, the use of the above-mentioned plastic parts must be increasingly restricted. In particular, for example, many cemetery administrations have already started to prohibit the use of plastics in cemeteries because of the fact that they can usually be disposed of in a way that is harmful to the environment. As described, however, molded parts with functional properties comparable to the above-mentioned molded plastic parts are urgently needed. With regard to the function as arrangements and/or decorative parts, one could think of the bases made of woven straw that were used in the past, i.e. before the plastic parts were used. The manufacture of parts from straw, which cannot replace the plastic moulded parts in every functional respect, involves dirty manual work and is very labor-intensive due to the individual production required. Parts made from corrugated cardboard are known for packaging moulded elements in particular, but also for arrangement bases. These are particularly sensitive to moisture, insofar as they are a replacement for the plastic parts mentioned in terms of the ability to be decorated with pointed objects, so that they are, at least as insulating parts and/or as bodies

for the fiannery arrangements, cannot be used satisfactorily.

The object of the invention is to create molded parts or bodies of the type mentioned at the beginning from a material which, with regard to adhesive, easily accessible holding of pointed objects such as in particular (adhesive) needles, wires, branches or the like, has a favorable low specific weight and, during use, resistance to external stress, e.g.

Resistance to moisture and weather influences, j is not inferior to the functional properties of the known plastic parts, whereby the molded part material should be characterized by the fact that it is biodegradable

&Idigr;5 and/or at least behaves in an environmentally neutral manner, so that overall a functional and environmentally friendly molded body with good insertion and adhesion of pointed objects, low specific weight, dimensional stability and stability, moisture-repellent properties and/or elastic properties that cushion external forces should be achieved.

This task is solved for the formation of a molded body of the type mentioned, subject to the properties that determine it, in that the material of the molded body consists of a large number of coconut fibers, similar fibers and/or chip-like particles bonded together by a binding agent, whereby fibers or chip-like particles run irregularly and are touched and/or cut by fibers or particles at irregular intervals at points of contact or intersection, once or several times. The molded body according to the invention consists of natural, biodegradable raw materials or at least of materials that are environmentally neutral. Coconut fibers

and/or equivalent^ and similar fibers, in particular cellulose fibers, and/or" chip-like cellular particles are available as a net material at low cost* In contrast to the previously common plastic molded parts, no harmful emissions are produced during (MÜÜ) combustion. The functional and handling properties of the molded body according to the invention meet the requirements in every respect. It has a specific weight that can be at least 0.4, but can also be achieved considerably less, e.g. with approx. 0.1. The structure of the molded body according to the invention is characterized by a loose arrangement of the fibers or particles, whereby these parts are nevertheless combined in a solid body with shape-retaining surfaces that are resistant to flat pressure or tensile stress. The entire body is solid and durable. A structure is achieved in which fibers or extending particles run irregularly, in particular in an arc and/or in a single or multiple winding and/or serpentine manner. The course of the fibers and the points of contact or intersection between the many fibers result in a continuity and/or permeability determined by the surrounding spaces or areas of the fibers within the body, i.e. in particular the formation of a large number of air areas or fiber/particle-free areas. A low specific weight or an air content of more than 50% in the body is obtained. The fiber/particle material ensures moisture (water) repellent and/or weather-resistant properties. The irregular, in this respect, confused arrangement of the fibers/particles in relation to the entire body also results in a certain internal, cushion-like elasticity. The internal molded body structure has excellent properties for attaching pointed objects such as needles, wires, etc.

or with directly pluggable objects such as f

twigs, branches or similar. Such objects allow ;:

They can be inserted into the body by light pressure, but <j they are then held firmly by the structure and only >

can be pulled out again by applying force. This makes it very easy and convenient to attach plants, flowers and/or decorative items to or in the molded body, so that you can create very versatile and attractive-looking arrangements such as wreaths, roman ornaments and much more.

, The bond or combination of the fibers or particles is achieved in a particularly expedient and preferred manner in that the molded body material comprises a binding agent which connects the fibers or particles to one another in the area of the contact or intersection points. In order to give the molded body a particularly large proportion of air, the connection is made at certain points, ie practically limited to the contact surfaces or points of contact between two fibers or particles. Such a connection, in which the binding agent has only a small weight % and volume proportion, is particularly advantageous l

and simply achieved by the binding agent consisting of -

an aqueous dispersion of natural or synthetic polishes (latex), preferably from latex-producing plants.

Another embodiment consists in the binding agent being made from a binding agent that can be liquefied under heat and solidified when cooled, such as paraffin, stearin, TalA resin and/or wax. Such a binding agent leads to a particularly inexpensively available molded body due to the associated ease of manufacture.

the fibers run in a (partial) space of the molded body that is common to them, at least in surface areas with respect to all spatial directions, essentially evenly distributed. This measure maintains the "disordered internal structure" of the molded body that determines the invention, but it is ensured that there are no preferred directions of fiber accumulations in the molded body, i.e., for example, special layers and/or different textures are avoided. This means that in the space of the molded body, essentially everywhere

Equivalent and equivalent structural components are provided ^, so that a pointed object can be inserted practically at any point in the molded body under the same pressure or force conditions. It is also possible to insert relatively deeply, possibly through the body, under uniform conditions. However, depending on the application, different textures/layers may also be desired and provided.

It is particularly expedient to provide the lengths of the fibers in such a way that the mass of the fibers is pourable. Apart from the fact that with fibers dimensioned in this way the manufacturability and the cost-effective availability of the molded body are particularly advantageous, such fiber lengths are particularly suitable for the inventive

Structure of the molded body relatively uniform over the |

entire space, i.e. without clumps or undesirable compaction. The length is only limited by the fact that, according to the invention, a type of "bush" is formed, which leaves air spaces between the fibers. In this respect, fibers or particles extending in a straight line, which run at a variety of angles to one another, i.e. irregularly according to this measure, can also be arranged.

A fibre can also have a lath outer, which ensures |

that it touches and/or intersects itself once or several times along its course. With such fibers or their course, a structure is achieved that has a special internal strength that does not impair the functional properties of the molded body.

It is particularly advantageous to provide the fibers in a density such that the molded body has an air content of more than 50%. Such a body has a particularly low specific weight, so that it is very easy to handle.

Further advantages, refinements and embodiments of the invention are apparent from the following schematic drawing. It shows

Fig. 1 a molded body according to the invention and

Fig. 2 shows a detail of an enlarged view of the structure of the molded body of Fig. 1.

As can be seen from Fig. 1 and 2, a molded body according to the invention in the form of a cross 1 comprises a spatial structure made of thread-like fibers 11,...,19,. .., air spaces 3 and binding agent 2. Coconut fibers are provided, which are particularly favorable with regard to later environmentally compatible and friendly disposal of the (arrangement) body after use.

Fibers of the structure have a winding and meandering course. For example, consider fiber 11, which touches itself at points 110 or intersects (crosses). In addition, fiber 11 is arranged in irregular

The fibers 11 to 19 are cut once or multiple times at intervals from other fibers that touch them, namely, among others, from the fibers 12 to 19 shown in Fig. 2. The respective contact or intersection points are provided with reference numerals 112 to 117. At the contact points/points 110 to 117, the fibers 11 to 19 are connected by the binding agent 2 at certain points, i.e. essentially only in the area of their actual contact surfaces/points. For this purpose, the composite in the described embodiment is made with latex as a binding agent. This means that relatively pronounced air spaces are formed between the fibers.

The described contact, arrangement and connection of the fibers is provided in every spatial direction or in every spatial area of the facer body. A limitation is provided by the surfaces 10 of the cross body 1, whereby the arms or the cross longitudinal part have a semicircular cross section. The surface is relatively finely structured due to the fiber structure of the body, so that it is self-contained. This means that essentially flat surfaces are obtained, although it is also possible, as can be seen from Fig. 1, for differently curved surfaces to intersect. In general, a large number of geometric shapes are possible for the molded body according to the invention, i.e. in particular the formation of singly or doubly curved surfaces, e.g. in the case of wave-shaped bodies or rotating bodies such as spheres or the like.

The shaped arrangement body 1 can be fitted with needles 4, e.g. U-shaped pins, wires that can pass through the whole body, stems or the like by applying light pressure, as these objects can be easily inserted into the body structure, but are held ^firmly in it. Thus, various objects, only indicated by dashed lines, can be fitted
