Three-dimensional arrangement

The invention relates to a collapsible three-dimensional arrangement with a system of hinged together Bar elements.

Well-known three-dimensional arrangements, such as those composed of individual elements as scaffolding in buildings used, require a lot of man-hours for assembly and subsequent disassembly; their transportation is difficult, and the same applies to storage, as the individual parts are bulky and you have to be careful that there are no parts get lost.

-2-, 209849/0805

It is therefore an object of the invention to address disadvantages of the known avoid three-dimensional arrangements.

According to the invention, this object is achieved in the case of one mentioned at the beginning Arrangement solved in that the arrangement has a first support element in the form of a two-dimensional framework, which the latter has a complex of articulated fields or parallelograms made up of networks of straight bar elements are formed, of which at least some / with each other form a certain angle, the rod elements of a network are each parallel to each other and joints are provided at at least some tips of these fields that at a distance from the first support element there is at least a second, articulated support element provided that articulated rods are provided are which at least part of the joints of the first support element with at least part of the joints of the second Connect the support element, these rods running obliquely to the direction of the folding plane of the arrangement and this direction is defined by the direction of a plane in which the rod elements come to lie, which are close to each other come to rest when the angles formed between them are practically closed. Such arrangements can be made with Methods of mass production inexpensively ready-made in factories and folded in their entirety, i.e. with small volume, transport and store. Before use, they are then unfolded or in a very short time -folded and brought into the desired position, which less well-trained staff can easily do. To Such an arrangement can then simply be folded up or folded up again and used until the next use store temporarily. Since such an arrangement can be folded flat, it can be conveniently placed on a vehicle, for example transport their entirety. Moreover, such a

Arrangement according to the invention from relatively few types of components put together, so that for these individual types one r-relative big series. In addition, this results in the advantage that the user of such an arrangement with a small number of spare parts for the Pail that once a part of the Arrangement should be damaged. Such arrangements can also be produced with different dimensions without difficulty because their modular structure allows great design freedom in this regard.

By suitable selection of the length of the rod elements and rods as well as the spacing of the holes and the types of the The connecting elements used in joints can be made in a wide variety of shapes, e.g. planar, cylindrical and spherical arrangements or arrangements in the form of a (horse) saddle.

Arrangements according to the invention can also be used on the construction site very easy, convenient and quick to use as they can be single; borrowed on the floor by pulling in a certain direction needs to unfold, they are then fixed by at least one rigid stiffening member in this unfolded position and they finally, e.g. by means of a crane, lifts up and then in place and place attached.

According to a particularly advantageous embodiment of the invention, the arrangement is designed so that the second support element is formed by a second framework, with at least some bar elements of the second framework defining fields, which are identical to those of the first framework and their geometric centers on those of the intersections of the Bar elements of the first truss are outgoing perpendicular.

^: So the second half-timbered structure is similar here to the first. Advantageously, at least some of the joints of a framework are each connected to four joints of the other framework via four inclined rods forming the edges of a pyramid with a rectangular plan. The inclined rods form triangles adjoining each other with the rod elements of the two trusses, the tips of which are directed alternately towards the one and the other truss. Furthermore, in at least one part of the arrangement, at least one prism-shaped volume, which has one of these triangles as a base, is advantageously defined by three cross members which have two pairs of rods and two rod elements, the ends of these rods and these rod elements being paired by the aforementioned Joints and the rods mentioned are connected and the elements of this volume are also connected at their crossing points by axes of rotation.

In order to obtain a flat arrangement, the projection triangles that converge towards a framework are isosceles and identical to the projection triangles that converge towards the other framework, with the axes of rotation of the cross members of the prism-shaped volume mentioned, which at the intersections " places are arranged, in the middle of the rods and the rod elements are arranged.

Other embodiments of the arrangement according to the invention are rod elements by varying the dimensions of its elements and rods possible.

Further details and advantageous developments of the invention emerge from those described below and Embodiments shown in the drawing, as well as from the dimensional relationships of the drawing,

It seems important to point out that the Pig. 1, 6 and 8 one hand and the Pig. 2, 7 and 9, on the other hand, are remodeled Are representations showing the result obtained by following the other corresponding ones Figures formed models in the folded and unfolded state photographed. These figures represent thus the proof that all arrangements can be folded up completely flat, and that they depending on the training in the unfolded state form an envelope which is flat or saddle-shaped or cylindrical. Incidentally, make it possible these figures, in space the exact position of the rod elements and rods in the folded and unfolded state of the arrangement to find, which would be far more difficult if these figures were missing and you could just do them in the conventional way drawn figures would be dependent.

According to the first embodiment (Fig. 1 to 5) is there shown fold-out three-dimensional arrangement of the type with flat envelope and with a rather high degree of static redundancy, i.e. that it contains many superfluous connections. To the description and that To facilitate understanding, it is assumed that this arrangement is horizontal, as is the case when the arrangement forms the framework or the grate of a floor or the supporting structure of a terrace roof.

The arrangement according to FIGS. 1-5 has an upper framework (Figs. 4A and 5), which from a first network (from each other

ooier Gfc

parallel tables 2 and a second network (from also mutually parallel rod elements 3 is formed, which last tere with the rod elements 2 each cross in the form of an X; in Fig. 5, all of these rod elements are thick shown in solid lines.

• ./9 209849 / 08C6

The rod elements 2 and 3 are connected by joints 4-, which are shown schematically by filled circles. The joints 4 are arranged at the intersections of the fictitious longitudinal lines L _2n, which have a straight rank, and the fictitious transverse lines QJo _n , which have a straight slope. The definition of these lines has already been given above, for example, is at the intersection of the lines L ^ and Q? _2, ^a joint 4 is arranged, which connects a rod element 2 to a rod element 3.

The arrangement also includes a lower framework 5 (Figs. 4-B and 5), which is constructed just like the framework 1, namely

od * f Gi ^- lter λ

of two crossed nets of rod elements 6 and 7 »which are drawn in Fig. 5 with thin, continuous lines.

The rod elements 6 and 7 are connected by joints 8, which are shown schematically by open circles. The joints 8 are located at the intersections of the fictitious longitudinal lines I _2n , which have an even rank, with the fictitious transverse lines tpn + 1, which have an uneven rank which are located in the same plane perpendicular to these trusses, by definition, have the same rank. For example, at the intersection of the lines I ^ and te is a joint 8, which a rod element 6 with a rod element

7 connects.

The two trusses 1 and 5 are identical in the sense that the fields defined by their rod elements are deformable parallelograms or diamonds with the same shape and the same Orientation are. However, these trusses are shifted against each other, in such a way that each of the lower joints

8 perpendicular to the geometric center of the corresponding

./1O 209849/0806

- ίο -

upper field are located and that as a result, the upper joints are each perpendicular to the geometric center of the corresponding lower field. [

The arrangement also has inclined rods, which the Connect the upper joints 4 to the lower joints 8 and are articulated at their ends.

The inclined bars are arranged in a special way to facilitate the folding and unfolding of the assembly enable. Referring to the Pig. 4D and 5 can be seen the following:

The inclined rods of a first series, denoted by 9, each connect an upper joint 4 with a lower joint 8, namely the joint 8 lies at the intersection of a transverse line with a slope one higher with a longitudinal line with one two higher Rank. For example, the rod 9 connects the upper joint 4 (T ₄ , L ₄ ) with the lower joint 8 (tr, Ig).

The inclined rods of a second series, denoted by 10, each connect an upper joint 4 to a lower joint 8, namely the joint 8 lies at the intersection of a transverse line which is one higher and a longitudinal line which is two lower. For example, the rod 10 connects the already mentioned upper joint (T ₄ , L ^) with the lower joint (tr, Ip)

The inclined rods of a third series, which are denoted by 11, each connect an upper joint 4 with the coordinates (^ _2n ι ^ 2 ) ^m ^ * a lower joint 8 with the coordinates Ct _2n-1 , I _{2n + 2} ), ^Ζ · ^Β · ( ^T 4 » ^L n) ^with ^ 3» ¹ S ^ '

./11 209849/0805

The inclined rods 12 of a fourth series each connect an upper joint 4- (Tpn * ^L 2n ^ ^m ^ ^e ^ ^nem lower joint 8 Ct _2n-1 , I _2n _2> » ^Ζ · ^Β · ^(T 4» ¹ V ^with ^ 3 » ¹ Z * '

It can thus be seen that the joints 4- of the upper framework 1 are each connected to four joints 8 of the lower framework 5 are, via four inclined rods 9 to 12, which the Form the edges of a pyramid with a rectangular plan. You can also see that two successive pyramids I3 and 14 overlap or intersect (see. Fig. 4-D), where cross the associated sloping rods in pairs. The same applies to those pyramids I5 and 16, the tips of which coincide with the lower joints 8.

On the other hand, when comparing FIGS. 40 and A-D, one sees that the inclined rods 9 to 12 have a foldable surface I7 form which, when projected onto the folding plane R, defines a zigzag line.

This zigzag surface can be found in all design variants in which the degree of static overdetermination is reduced without, however, destroying the stability of the assembly as a whole.

In the case of an arrangement of the type described above, it has already been said that one can also distinguish between a series of bar elements, each of which forms an X, e.g. a ^ -b ^., Ap-bp, a, -b, ... (Fig. 5) or a ¹ ^ -b ¹ ^, a'p-b'o »a ', _{-b' 7} , etc. ... for the upper framework and **, .- ji, etc. ... for the lower framework, without speaking of the end parts. In order to give the arrangement more cohesion in its unfolded state, pivot points or pegs can be provided, e.g. i ^, i _p , I ₇ , or i '^, i'2 »i'3 ^at the intersection of the respective X. , or at least at some of these crosses, where these

./12

209849/0805

Axes of rotation run perpendicular to the respective pairs of rods. Such axes of rotation can advantageously be provided at at least some of the intersection points of the articulated rods, as far as these rods are in place. InFig. 3 are these axes of rotation with 21 to 24 have been designated. *

It should be pointed out that in this way one has formed series of X, so to speak, eg one series with a ^ -b ^, κ ^ Λ) ^ a, -b ,, and another series with a '^ - b ¹ ^ , a'p-b'p, a ', - b' ,. In these rows, the X are each connected to the X of the adjacent row via the joints 4, eg the X & o ~ ^ 2 to the X a'p "" ⁰ '? » ^w * ^e ^ ^as ^ β5 clearly shows.

In the present "flat" embodiment according to FIGS. 1-5, the various rows of a framework lie each in the same plane. In the other, conforming exemplary embodiments according to the invention, e.g. according to FIG. 6 and 7 or FIGS. 8 and 9 * this is not the case.

In the embodiment according to FIGS. 6 and 7, the outer Envelope of the unfolded arrangement has the shape of a horse = saddle and is related to a hyperbolic paraboloid. In fact, as can be seen from FIG. 7, it represents a convex curvature in the transverse directions and a concave curve Curvature in the longitudinal directions. In this case, all triangles 19 and 20 are isosceles and preferably equal = identical on both sides and with each other, whereby the axes of rotation are not in the middle of the rod elements.

In the embodiment according to FIGS. 8 and 9, the outer Envelope of the unfolded arrangement is cylindrical. In this case, as Fig. 8 clearly shows, all are "projection" triangles isosceles, but the triangles 19, “the point of which is directed towards the upper framework, have a smaller base than the triangles 22, the point of which is towards the lower framework

^: ./13

209849/0805

is directed. Spoken in other words; The lower rod elements are shorter than the upper rod elements. here the axes of rotation are arranged strictly in the middle of the rod elements.

The arrangement according to FIG. 10 shows like that according to FIG. 5 an unfolded arrangement showing an upper articulated framework with thick continuous lines and thin continuous lines Lines showing a lower articulated framework, which are connected to one another by articulated rods, which form the joints of the one Connect the framework with those of the other. In contrast to FIG. 5, where the bar elements of a framework are connected to one another form an X, they each form a V, the one on his Ends and is articulated at its tip, resulting in equivalent possibilities as in Fig. 5. However, since the Fields are more flexible here, rod elements are useful as connections between the two trusses C ^, Cg, C, etc ... provided which the top table elements a ,,, b ^, ... with the lower bar elements o ^, associate. The "conventional folding plane" is here the projection plane according to FIG. 11, but it should be pointed out here that that every flat arrangement according to the invention, be it that of FIG. 10 or that of FIG. 5, has another orientation having a possible folding plane, namely that of the two basic frameworks.

In order to keep the arrangement - regardless of the type - in the unfolded position, there are various possible solutions.

In a first embodiment, the wrist joints 4 and / or 8 of the assembly are on the hand beams (e.g. P in Fig. 4c) that structure is attached, the part of which forms the arrangement according to the invention.

209849/0805

According to a second embodiment, some upper joints 4 and / or some lower joints 8 of the arrangement are rigidly expanded, namely by elongated elements which extend vertically or parallel to the folding plane H and extend adapt exactly to the shape of the envelope of this arrangement. Such elements can obviously be replaced by tension members, e.g. chains, ropes or the like, which are permanent are attached to certain joints.

According to a third embodiment, some are of the above Joints 4 and / or the lower joints 8 and / or the axes of rotation (e.g. 21, 22, 23 or 24 in Fig. 3) locked to each To prevent pivoting of the rod elements 2, 3 and the rods 9 to 12 in relation to one another.

These different embodiments can naturally be related to one another be combined. In addition, the rod elements and the rods of flat iron or shaped rods with at least a flat flange. They can also be made of pipes with circular, square, rectangular or any other suitable cross-section.

FIGS. 12 to 14 show an embodiment of the joints 4 and 8. Eight elements end at each of these joints, namely Bar members and inclined bars; these elements are designed here as tubes.

Each joint has a knot 30 with a half sleeve 31, in which a tube 32 is arranged and - e.g. by means of a screw - can be fastened. This tube 32 is intended form an element which makes it possible to keep the assembly in its unfolded state.

The hemispheres 31 is integral with four converging ribs 33 to 36 formed.

./15 209849/0806

The ribs 33 and 34 lie in one plane, since they are the joint members 37 of the rod elements 2a and 3a ask which one the latter, for example, should form the upper framework. These joint members 37 are arranged in four holes 38.1 and 38.2 (Fig. 12), which are arranged at the corners of the longitudinal ribs 33 and 34 are.

The ribs 35 and 36 form an angle with each other, which is the one of triangles 19 and 20 (Fig. 1, 3i 6, 8) corresponds. In the embodiment according to FIG. 3, this angle is 60 °.

The longitudinal rib 35 has two holes 39.1 at its corners (Fig. 13) and 39.2 (FIG. 14) for receiving the joint members 37, which make it possible to articulate the inclined rods 9 and 10, respectively.

The longitudinal rib 36 also has two holes at its corners

40.1 (Fig. 13) and 40.2 (Fig. 14) for receiving the joint links 37 »which make it possible to articulate the rods 11 and 12, respectively.

Looking at holes 38.1 »39.1 and 40.1 in the Are close to the cutting plane ΧΙΊΙ-ΧΙΙΙ, it should be noted that the tube 2a above the longitudinal rib 34- (with reference to Fig. 13) is arranged, and that the other tubes 9, 11 and 3a at Rotation about tube 32 on the same side of the longitudinal ribs 35 »36 and 33 are arranged as the tube 2a relative to Longitudinal rib 34. - If, on the other hand, one looks at holes 38.2,

39.2 and 40.2, which are arranged at the level of the cutting plane XIV-XIV, it can be seen that the tube 3a is arranged below the longitudinal rib 34 (FIG. 14) with reference to FIG. 14, the other tubes 10, 12 and 2a as before with respect to their associated longitudinal ribs 35 »36 or 33, the same relative IjO for α einhiimn as the tube 3a relative to the longitudinal rib 33.

./16 209849/0805

If you have an inventive arrangement in this way with Equipped with such joints, the tubes 2a and 3a never cross, as they are never in the same plane. The same applies to tubes 6a and 7a >> 9 and 10, 11 and 12. In addition, the arrangement of the tubes on the longitudinal ribs 33 to 36 and the arrangement of the joint members 37 are possible and also convenient, as the two tubes and joint links associated with a specific longitudinal rib can never interfere with one another, because they are arranged on two different sides of this longitudinal rib.

Variants are of course possible. For example, the tubes 2a, 9 »11» etc. can be more or less flattened, at least at their end. The recess 31 is also not necessarily required and can be omitted.

In a flat arrangement (Figs. 1 and 2), the articulation members 37 are simple rods with a single degree of freedom the movement. So they can be formed by bolts, rivets or the like.

If, on the other hand, the arrangement is conformal, i.e. not flat, (Figs. 6, 7, 8 and 9)> one can be satisfied with providing sufficient play between the rods, which the hinge members 37 form and between the holes provided in the junction piece 30 and / or the tubes to to get at least one additional degree of freedom.

However, it appears to be more advantageous to have an inserted joint with a certain rotational mobility with respect to its center point to be provided on the pipes, and then the corresponding Longitudinal rib of the node to attach a rod that extends this joint. In this case, the same Art of the assembly for the axes of rotation 21 to 24 can be used.

./17 209849/0805

Joints 4 and 8 can also be made in a simpler way are, in particular with adapted (conformal) arrangements, As can be seen from Fig. 3, the rod elements 2a or 3a (or 6a and 7a) and the rods 9 and 12 on a circular; shaped ring 41 are lined up, which before assembly is open and then closed in a suitable manner.

In any case, in all joints 4, 8 and the axes of rotation 21 to 24, the joint axes are at least folded together State parallel to the folding plane R.

Figs. 15 to 17 show a joint variant that is particularly * this is suitable for an arrangement according to FIGS. 10 and 11 with bar elements which can be collapsed in each of the trusses V-shaped structures form »The joints belong to the upper framework and are shown in the unfolded state.

The joint component of the joint is formed by a rigid metal piece 30 having a star-shaped sectional shape having a star shape which radiating longitudinal ridges. See Fig. 16 _t but which may be asymmetric, as Fig. 17 shows. On the longitudinal ribs of this node piece, the tubular table elements and the rods, for example, can be pivoted, to be precise thanks to axes of rotation 38.1, 39.1 »which run perpendicular to the longitudinal ribs. Analogously to FIGS. 12 to 14, the elements of a V of the upper framework have been designated by 2a, 3a; the V with the opposite tip is 2'a, 3'a. The articulated rods 9 »9 ¹ are articulated on longitudinal ribs with a suitable inclination. The rod elements C *, which are also hinged to longitudinal ribs, form additional connections which are peculiar to the arrangement according to FIGS.

Such a joint enables the convergence of the forces at a single imaginary point so / ie the folding. Or - flaps the arrangement. If you want to fold the arrangement

./18

209849/0806

so pivot the rod elements 2a and 3a as well as 2'a and 3'a of the
V-elements around their respective joint links until they are at least nearly parallel to each other. ,>

The arrangement according to the invention can be used to create floors, false ceilings, suspended walls, roofs of flat and cylindrical shape and of the farm of a hyperbolic paraboloid, for lids, domes, etc., for permanent and for re-demolishable structures, for
Creation of fire protection walls, wind protection walls, snow protection walls, etc. for installation in the open air, for the creation of scaffolding and the like.

For the creation of collapsible shoring from
Buildings, e.g. for barns, hangars, bridges etc. You can
assemble various preferably flat sections,
which are oriented differently and each of which consists of one
three-dimensional arrangement according to the invention; in this case, a sequence of rod elements of one of these sections is formed together with a sequence of rod elements of the adjoining one
Partly to assemble them and the shoring to
