FIG /2 FIG //0 CONSTRUCTION SET FOR THE PRODUCTION OF STRUTTING ARRANGEMENTS BACKGROUND OF THE INVENTION The present invention relates to a construction set for the production of strutting arrangements, which preferably has a skeleton-like character and which can be used for the production of supports, supporting constructions, frame constructions connecting arrangements, scaffoldings, reinforcing arrangements, suspension arrangements and the like. A particular characteristic of the construction set according to the invention is that its individual elements can be connected by plug connections and possibly without a bore hole by'screw connections, whereby no limits are set to the user of this construction set with regard to the possibilities of variation. A further general and important characteristic of this construction set according to the invention consists in that the individual elements can be combined with one another with the use of inside grooved profiles by insertion of angular connecting parts, whereby this also comprises connecting parts with socalled rounded edges. In this way the greatest possible variability of use and fields of application of the construction set according to the invention is possible.

According to a further, preferred embodiment a clamp connection of individual elements is used beside the plug connection. Furthermore, according to a further embodiment an adhesive connection of individual elements can also be provided.

The construction set according to the invention for the production of strutting arrangements is well suited, for example, for the production of skeleton structures for balconies, which possibly also carrysheathing for the balcony. The result of combining the individual elements is a completely covered skeleton for a balcony.

The essence of the invention will now be explained in detail on the basis of the attached drawings which illustrate the covered balcony skeleton by way of example.

DESCRIPTION OF THE PREFERRED EMBODIMENT According to the invention this task will be solved through a construction set of strutting arrangement elements, which in the case of this example are to be defined as balcony sheathing elements, which elements can be combined or put together logically into a balcony sheathing or covering. I

These balcony sheathing elements according to the invention contain both the actual sheathing frame or skeleton and the equipment of this framework with dressing elements, which are known per se, and which have particularly the form of facing panels, made of weather resistant material.

A further aspect of the present invention consists in that the individual elements of the construction set for the production of balcony facings consist of an easily moldable or castable material, particularly of aluminum castings. t I

The embodiment of the invention, described above and given by way of example, will. now be explained in detail on the basis of theattached FIGS. 1 to 14, representing the preferred embodiment.

The FIGS. 1 and 2 each show perpendicular sections A through the base element, whereby the sectional planes stand perpendicularly one on top of the other.

FIG. 3 shows in perspective and broken'away at one end the so-called central bar 2 which is slipped on the upper part la of the base element and which is connected there by screw connection or by adhesive connection in one piece with the base element 1. According to a preferred embodiment, the upper part la of the base element 1 has the shape of a cut stone which has guide ribs at its four corners which are guided in the correspondingly developed

corners

2b, 2b, 2b"and 2b of the central bar 2.

On the upper end of the central bar 2, the upper closing element 3 is seated, which is shown in the FIGS. 4 and 4a in section and in top view.

The lower part 3a of this closing element corresponds in its geometry to the upper part la of the base element. Connected in one piece, this lower part 3a is succeeded by a closing plate 3b arranged at a right angle to it, which plate has bores 3c for the reception of the handrail. This handrail, shown in FIG. 5 in section, has reference number 4. Screw elements 4a can be provided, for example, for a screw connection.

As can be clearly seen from FIG. 3, the central bar 2 has an octagonal cross section, whereby, as has been explained already, the two shorter opposite sides have guide ribs in each case as the result of an undercutting arrangement. As a result of these guide ribs, one can also define this central bar 2 as a profile with inside grooves. As a result of this type of arrangement of the undercuttings not only these desirable inside grooves or guide ribs develop, but in the inside of the central bar there develops, at the same time, the so-called

guide corners

2b, 2b, 2b", and 2b, which are of importance for safe guidance of the correspondingly structured elements to be inserted into the central bar. An additional function of these inside grooves will be described further on. As can further be seen from FIG. 3, at least in one inside groove a rubber or plastic decorative strip 2a is disposed, as a result of which an esthetic effect is achieved while also functioning to guard against injuries.

For a right angle deflection of the handrail 4, for example, the so-called. corner piece 5, disclosed in the FIGS. 6 and 7, is a constituent part of this construction set according to the invention, which has anchoring elements b which cooperate with the correspondingly dimensioned and structured underside of the handrail 4a.

In FIG. 8 another important element of the present invention is disclosed, namely, the transverse connection 8 between two central bars, which are not shown in FIG. 8. The elements 8a and 8b correspond in their structure and geometry to the upper part la of the base element 1, that is, they are introduced into the central part from above and are anchored there in a manner known per se, whereby the central bar has the function of a sheathing. The two perpendicular anchoring elements 8a and 8b of the connecting bar 8 are connected in one piece with the actual, horizontally lying bar element 80 which has been created and is suitable as a support for the handrail.

Another essential element of the construction set according to the invention for strutting arrangements is shown in FIG. 9. Here, we are dealing with an angle element which is used whenever the balcony sheathing is to be arranged in front of the edge of the cantilever. In this case, a properly dimensioned hole is made in the front wall of the cantilever in which the anchoring element 9b is then inserted or preferably cemented which at its lower end has a type of barb structured element 9a. The closing plate 9e constitutes the closure with the cantilever front side which is then succeeded by a block-like element 90 on which is placed the upper part 9d at right angles to the axis of the anchoring part 9b which upper part serves for the reception of the central bar which is suitably structured for the reception in the central bar, which again functions as a sheathing.

In FIG. 10 another essential combination of elements of the construction set according to the invention for the production of strutting arrangements has been disclosed; this combination of elements consists of a C profile-like strip 10a, which, in a novel manner, connects central base of the overall combination according to the invention in any number and in any desired arrangement as to height. In this C profile-like strip a correspondingly dimensioned, preferably square, supporting plate 10b has beed disposed, which has on its frontside a screw connection element 100, for example, with grub screw closure 10d. This screw coupling element 100 likewise holds C profile-like balcony facing strips or facing plates 10e. These balcony facing strips or facing plates frequently consist of a material with a high heat expansion coefficient. A surprising progress achieved with the present invention is that thermal adjustment of length can take place without difficulty through the fact that the holding plate 10b travels in the C profile of the strip 10a, that is, it can travel glidingly to the left or to the right depending on the heat expansion or cold construction of the material of the facing strip 102. Y I

FIG. 11 shows the assembly of the combination of parts presented in FIG. 10. The balcony plate 110 carries the combination of the base element and central bar 2, designated by reference numeral 11b whereby the C profile-like strips 10a are attached to the central bar, for example, are screwed together, and, then, the arrangement is made for the attachment of the facing strip l0e, which has been drawn in detail in FIG. 10.

FIG. 11a shows in somewhat larger scale a preferred embodiment of the attachment of the C profile-like strip 10a to the central bar 11b. As was explained above, the central bar according to a preferred embodiment has inside grooves which have been designated in FIG. 3 with the reference numeral 2a. In one of these inside grooves runs a screw 10a with its head 100" facing the inside of the central bar which cooperates with a counterscrew 10a in the manner shown in FIG. lla so that upon tightening of the counterscrew 100' one will achieve a jamming or tie up of the C profilelike strip 10a at any desired height without the need for any kind of borehole arrangement.

FIG. 12 shows a further variation of the construction set according to the invention whereby for the purpose of increasing the stabilization of the sheathing construction the construction arrangement 12b, which has been disposed with the use of a construction element 7 of the FIG. 9, has been supported in a reinforcing manner via a connecting element 12c which consists essentially of the connecting bar 8 shown in FIG. 8, by the combination 12d of central bar and base element.

FIG. 13 illustrates this reinforced support in the same manner with the variation that the front and rear central bar, lower part constructions 13b and 13e, which are seated in the balcony floor plate 13a and connected by the connecting bar 130, are both inserted from above into this plate.

FIG. 14 shows a further method of application of the construction set according to the invention for strutting arrangements, from which one can see moreover, that the use of this total combination or sub-combination suitable for balcony sheathings, can also be used in other building areas, for example, for the construction of high-grade garden fences. In FIG. 14, the reference number 14a designates the ground pedestal at the end of a piece of ground on which the combination 14b lower part central bar has been arranged from above, the corner piece central bar combination 14b has been arranged from the side, whereby these two perpendicular elements have been connected by the connecting bar which in FIG. 14 is designated by reference numeral and which has already been explained in detail in connection with the FIG. 8. t
