Abstract

The invention relates to a supporting trellis framework comprising interconnected trellis bars, some of said bars extending in the longitudinal direction of the supporting trellis framework and some directly or indirectly connecting said longitudinal bars. The connecting bars are connected to the longitudinally extending bars in such a way that the distance between the longitudinally extending bars can be reduced when the framework is folded up and increased when the framework is opened out. At least one of the longitudinally extending bars is fixed in such a way that it is maintained in position when the framework is folded up and when it is opened out, and at least one other longitudinally extending bar is arranged in a mobile manner in such a way that it moves when the supporting framework is folded up and opened out.

Erfindungsgemäß ist somit vorgesehen, dass beim Ein- und Ausfalten wenigstens einer, vorzugsweise mehrere der in Längsrichtung des Gittertragwerkes verlaufenden Gitterstäbe an Ort und Stelle verbleibt, das heißt keine Bewegung erfährt, wohingegen weitere in Längsrichtung verlaufende Gitterstäbe relativ dazu bewegt werden. Eine solche Ausgestaltung der Erfindung ermöglicht es, das Gittertragwerk ortsfest über die feststehenden, in Längsrichtung verlaufenden Gitterstäbe anzuordnen und bei Bedarf auszufalten bzw. einzufalten.According to the invention it is thus provided that when folding and unfolding at least one, preferably more of the lattice bars extending in the longitudinal direction of the lattice support structure remains in place, that is, no movement, whereas further longitudinally extending bars are moved relative thereto. Such an embodiment of the invention makes it possible to arrange the lattice support station fixed on the fixed, extending in the longitudinal direction of the bars and fold if necessary or fold.
Die Erfindung betrifft des Weiteren ein Gittertragwerk, das miteinander in Verbindung stehenden Gitterstäbe aufweist, wobei das Gittertragwerk in Längsrichtung des Gittertragwerkes verlaufende Gitterstäbe sowie diese unmittelbar oder mittelbar verbindende Gitterstäbe aufweist, wobei die verbindenden Gitterstäbe mit den in Längsrichtung verlaufenden Gitterstäben derart in Verbindung stehen, dass der Abstand der in Längsrichtung des Gittertragwerkes verlaufenden Gitterstäbe beim Einfalten des Gittertragwerkes verringerbar und beim Ausfalten des Gittertragwerkes vergrößerbar ist. Weiterhin ist vorgesehen, dass wenigstens zwei der in Längs- richtung verlaufenden Gitterstäbe derart angeordnet sind, dass sie beim Einfalten sowie beim Ausfalten des Gittertragwerkes eine in Längsrichtung des Gittertragwerkes verlaufende Relativbewegung zueinander vornehmen.The invention further relates to a lattice support structure, which has interconnected grid bars, wherein the lattice support structure in the longitudinal direction of the lattice support running lattice bars and these directly or indirectly connecting bars, wherein the connecting bars are in communication with the longitudinally extending bars in such a way that the distance between the running in the longitudinal direction of the lattice support structure bars when folding the lattice support structure can be reduced and enlarged during the unfolding of the lattice support structure. Furthermore, it is provided that at least two of the longitudinal Direction extending bars are arranged so that they make a folding in the longitudinal direction of the lattice support work relative to each other during folding and unfolding of the lattice support structure.
Die die in Längsrichtung verlaufenden Gitterstäbe verbindenden Gitterstäbe sind somit derart mit den in Längsrichtung verlaufenden Gitterstäben verbunden, dass die erfindungsgemäße Relativbewegung möglich ist.The bars connecting the longitudinal bars extending bars are thus connected to the longitudinally extending bars so that the relative movement according to the invention is possible.
Denkbar ist es, dass mehrere in Längsrichtung des Gittertragwerkes verlaufende Gitterstäbe parallel bewegt werden und zwar relativ zu mehreren in Längsrichtung des Gittertragwerkes verlaufenden Gitterstäben. So ist es beispielsweise denkbar, dass vier sich in Längsrichtung verlaufende Gitterstäbe vorgesehen sind, von denen sich jeweils zwei synchron bewegen und dass beim Ein- und/oder Ausfalten des Gittertragwerkes zwei in Längsichtung verlaufende Gitterstäbe relativ zu zwei weiteren in Längsrichtung verlaufenden Gitterstäben eine Bewegung durchführen. Selbstverständlich ist die Erfindung nicht auf Gittertragwerke mit vier in Längsichtung verlaufenden Gitterstäben beschränkt. Auch eine geringere oder größere Anzahl ist denkbar und von der Erfindung mit umfaßt.It is conceivable that a plurality of grid bars extending in the longitudinal direction of the lattice support structure are moved in parallel, relative to a plurality of lattice bars running in the longitudinal direction of the lattice support structure. Thus, for example, it is conceivable that four longitudinally extending bars are provided, two of which move synchronously and that perform when moving in and / or unfolding the lattice structure two longitudinally extending bars relative to two other longitudinally extending bars , Of course, the invention is not limited to lattice structures with four extending in longitudinal direction bars. Also, a smaller or larger number is conceivable and covered by the invention.
Das Gittertragwerk nach Anspruch 2 kann dadurch gekennzeichnet sein, dass es gemäß dem kennzeichnenden Teil des Anspruchs 1 ausgeführt ist, dass also feststehende, sich in Längsrichtung erstreckende Gitterstäbe vorgesehen sind.The lattice support structure according to claim 2 may be characterized in that it is designed according to the characterizing part of claim 1, that is to say fixed, longitudinally extending lattice bars are provided.
Es kann vorgesehen sein, dass die in Längsrichtung verlaufenden feststehenden Gitterstäbe und die in Längsrichtung verlaufenden bewegbaren Gitterstäbe bzw. die relativ zueinander bewegbaren in Längsrichtung verlaufenden Gitterstäbe abwechselnd aufeinander folgen.It can be provided that the longitudinally extending stationary bars and the longitudinally extending movable bars or the relatively movable longitudinal bars extending in succession follow each other alternately.
In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass die in Längsrichtung verlaufenden bewegbaren Gitterstäbe beim Einfalten sowie beim Ausfalten des Gittertragwerkes eine Bewegung erfahren, durch die der Abstand sowie die relative Position in Längsrichtung des Gittertragwerkes der in Längsrichtung verlaufenden bewegbaren Gitterstäbe zu den in Längsrichtung verlaufenden feststehenden Gitterstäben verändert wird. Denkbar ist es also, dass die in Längsrichtung verlaufenden bewegbaren Gitterstäbe beim Ein- bzw. Ausfalten auf die feststehenden Gitterstäbe zu bewegt werden bzw. von diesen weg bewegt werden und dass zusätzlich zu dieser Abstandsveränderung eine Relativbewegung der feststehenden und bewegbaren Gitterstäbe in axialer Richtung, das heißt in Längsrichtung des Gittertragwerks erfolgt.In a further embodiment of the invention, it is provided that the longitudinally extending movable bars when moving and when unfolding the lattice support movement undergo a movement through which the distance and the relative position in the longitudinal direction of the lattice support running in the longitudinal direction movable grid bars is changed to the longitudinally extending fixed bars. It is therefore conceivable that the longitudinally extending movable bars are moved to the fixed bars during insertion or unfolding or moved away from them and that in addition to this change in distance, a relative movement of the fixed and movable bars in the axial direction, the is done in the longitudinal direction of the lattice structure.
Die verbindenden Gitterstäbe können schwenkbar und/oder verschieblich mit den in Längsrichtung des Gittertragwerkes verlaufenden Gitterstäben in Verbindung stehen. Denkbar ist es, dass die verschiebbare Anbindung dadurch erreicht wird, dass die Gitterstäbe vorzugsweise schwenkbar mit Gleithülsen in Verbindung stehen, die auf den in Längsrichtung verlaufenden Gitterstäben laufen.The connecting bars can be pivotally and / or displaceably connected to the extending in the longitudinal direction of the lattice support structure bars. It is conceivable that the displaceable connection is achieved in that the bars are preferably pivotally connected to sliding sleeves, which run on the longitudinally extending bars.
Die verbindenden Gitterstäbe können vorzugsweise in der Außenfläche des Gittertragwerkes liegen diese bilden.The connecting bars may preferably be located in the outer surface of the lattice support structure.
Die in Längsrichtung des Gittertragwerkes verlaufenden Gitterstäbe können die Außenkanten des Gittertragwerkes bilden.The extending in the longitudinal direction of the lattice support structure bars can form the outer edges of the lattice support structure.
Die Form des Gittertragwerks ist nicht beschränkt. Somit ist es denkbar, im Querschnitt dreieckige, quadratische, rechteckige oder polygonale Gittertragwerke vorzusehen.The shape of the lattice structure is not limited. Thus, it is conceivable to provide in cross-section triangular, square, rectangular or polygonal lattice structures.
Dabei werden die Eckpunkte dieser Gittertragwerke vorzugsweise durch die in Längsrichtung des Gittertragwerkes verlaufenden Stäbe gebildet.The corner points of these lattice structures are preferably formed by the extending in the longitudinal direction of the lattice support rods.
Vorzugsweise weist das Gittertragwerk eine sich in Längsrichtung wiederholende Struktur aus in Längsrichtung verlaufenden Gitterstäben sowie verbindenden Gitterstäben auf. In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass wenigstens ein Teil der verbindenden Gitterstäbe durch Verbindungsstreben gebildet werden, die sich im ausgefalteten Zustand des Gittertragwerkes senkrecht zur Längsrichtung des Gittertragwerkes von einer zu einer anderen der sich in Längsrichtung des Gittertragwerkes erstreckenden Gitterstäbe erstrecken.Preferably, the lattice support structure has a longitudinally repeating structure of longitudinally extending bars and connecting bars. In a further embodiment of the invention, it is provided that at least part of the connecting bars are formed by connecting struts extending in the unfolded state of the lattice structure perpendicular to the longitudinal direction of the lattice structure from one to another extending in the longitudinal direction of the lattice support structure bars.
Diese Verbindungsstreben können über wenigstens ein Gelenk verfügen, mittels dessen sie zwischen einen eingefalteten und einem ausgefalteten Zustand verstellbar sind.These connecting struts may have at least one joint, by means of which they are adjustable between a folded and a folded state.
In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass die verbindenden Gitterstäbe wenigstens teilweise miteinander in Verbindung stehen. Denkbar ist es, dass in Längsrichtung des Gittertragwerkes voneinander beabstandete verbindende Gitterstäbe beispielsweise über ein Gestänge oder über einen Mechanismus miteinander in Verbindung stehen, mittels dessen der Abstand der verbindenden Gitterstäbe zueinander variierbar ist. Dieser Mechanismus kann dazu genutzt werden, das Einfalten bzw. Ausfalten des gesamten Gittertragwerkes zu bewirken.In a further embodiment of the invention, it is provided that the connecting bars are at least partially in communication with each other. It is conceivable that in the longitudinal direction of the lattice support structure spaced connecting bars are for example via a linkage or a mechanism in communication with each other, by means of which the distance of the connecting bars is mutually variable. This mechanism can be used to effect the folding or unfolding of the entire lattice structure.
Um sicherzustellen, dass das ausgefaltete Gittertragwerk nicht unerwünscht kollabiert, kann vorgesehen sein, dass das Gittertragwerk Arretierungsmittel aufweist, mittels derer die verbindenden Gitterstäbe in wenigstens einer Position fixierbar sind.To ensure that the unfolded lattice support structure does not undesirably collapse, it can be provided that the lattice support structure has locking means by means of which the connecting lattice rods can be fixed in at least one position.
Wie oben ausgeführt, können Mittel vorgesehen sein, die auf wenigstens zwei der verbindenden Gitterstäbe derart einwirken, dass der Abstand der verbindenden Gitterstäbe zueinander vergrößerbar oder verkleinerbar ist, wodurch sich das Gittertragwerk einfaltet oder ausfaltet.As stated above, means may be provided which act on at least two of the connecting bars such that the spacing of the connecting bars is mutually enlargeable or reducible, whereby the grid structure folds or unfolds.
Diese Mittel können beispielsweise durch ein motorisch, pneumatisch, hydraulisch oder anderweitig betriebenes Gestänge gebildet werden, das auf die verbindenden Gitterstäbe einwirkt. Grundsätzlich ist es selbstverständlich ebenso denkbar, dass Mittel vorgesehen sind, die auf die in Längsrichtung des Gittertragwerkes verlau- fenden Gitterstäbe aufwirken und zwar derart, dass deren Abstand zueinander vergrößert oder verkleinert wird, so dass das Gittertragwerk ausgefaltet oder eingefaltet wird.These means can be formed for example by a motor, pneumatically, hydraulically or otherwise operated linkage, which acts on the connecting bars. In principle, it is of course also conceivable that means are provided which extend to the longitudinal direction of the lattice support structure. fenden bars act in such a way that their distance from each other is increased or decreased, so that the lattice structure is folded or folded.
In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass wenigstens zwei der verbindenden Gitterstäbe über Kreuz verlaufen und an ihrem Kreuzungspunkt mit einem weiteren der verbindenden Gitterstäbe in Verbindung stehen.In a further embodiment of the invention it is provided that at least two of the connecting bars extend crosswise and are at their intersection point with another of the connecting bars in combination.
Weiterhin kann vorgesehen sein, dass wenigstens zwei der verbindenden Gitterstäbe über Kreuz verlaufen und an ihrem Kreuzungspunkt mit einem weiteren der verbindenden Gitterstäbe in Verbindung stehen und dass der Kreuzungspunkt mit dem Gelenk des weiteren verbindenden Gitterstabes in Verbindung steht.Furthermore, it can be provided that at least two of the connecting bars extend crosswise and are connected at their crossing point with another of the connecting bars and that the crossing point is in communication with the joint of the further connecting bar.
Die Erfindung betrifft des weiteren ein Gittertragwerk mit aufspreizbaren Strukturen, insbesondere ein Gittertragwerk nach einem der Ansprüche 1 bis 16, wobei das Gittertragwerk schwenkbar angeordnete Gitterstäbe aufweist, wobei die schwenkbare Verbindung derart ausgeführt ist, dass eines der miteinander schwenkbar verbundenen Teile einen Vorsprung aufweist und dass das andere der schwenkbar verbundenen Teile eine auf drei Seiten durch Wandungen begrenzte Nut aufweist, in der der Vorsprung des anderen Teils verschwenkbar aufgenommen ist. Der Nutboden dient somit als Begrenzung, so dass ein Verschwenken des Gitterstabes nur soweit möglich ist, bis das eine der genannten Teile an dem Nutboden aufliegt. In dieser Position ist der Gitterstab somit blockiert bzw. ein weiteres Verschwenken ist nicht möglich. Eine derartige schwenkbare Verbindung kann dort vorgesehen sein, wo zwei Segmente eines Gitterstabes schwenkbar miteinander in Verbindung stehen und/oder wo ein Gitterstab an einem anderen Teil des Gittertragwerks angelenkt ist.The invention further relates to a lattice support structure with expandable structures, in particular a lattice support structure according to one of claims 1 to 16, wherein the lattice support structure pivotally arranged bars, wherein the pivotable connection is designed such that one of the pivotally connected parts has a projection and that the other of the pivotally connected parts has a limited on three sides by walls groove in which the projection of the other part is pivotally received. The groove bottom thus serves as a boundary, so that a pivoting of the grid bar is only possible as far as possible, until one of said parts rests against the groove bottom. In this position, the grid is thus blocked or further pivoting is not possible. Such a pivotable connection may be provided where two segments of a grid bar pivotally communicate with each other and / or where a grid bar is hinged to another part of the lattice support structure.
Der Gitterstab kann an seinem einen Endbereich den Vorsprung und an seinem anderen Endbereich die genannte Nut aufweisen. Auf diese Weise ist es möglich, mehrere Gitterstäbe miteinander zu verbinden bzw. Gitterstäbe unterschiedlicher Länge bereitzustellen. Grundsätzlich ist auch denkbar, beiden Enden des Gitterstabes mit Nuten oder mit den genannten Vorsprüngen auszuführen.The grating bar may have the projection at its one end region and the said groove at its other end region. In this way it is possible to connect several bars together or bars different To provide length. In principle, it is also conceivable to carry out both ends of the lattice bar with grooves or with the said projections.
Besonders vorteilhaft ist es, wenn eine Brems- bzw. eine Fixiereinrichtung vorgesehen ist, die die Gitterstäbe in einer bestimmten Schwenkposition fixiert. Dabei kann es sich beispielsweise um eine Trommel-, Scheiben oder Backenbremse handeln. Die Bremse kann z.B. hydraulisch oder mechanisch betätigt sein. Die Bremse kann Bremsbacken aufweisen, die zwei Vorsprünge aufweisen, die bei Betätigung der Bremse gleichzeitig mit dem jeweils benachbarten Teil, beispielsweise mit dem genannten Vorsprung in Kontakt tritt und so eine optimale Bremswirkung entfaltet.It is particularly advantageous if a brake or a fixing device is provided which fixes the grid bars in a specific pivot position. This may be, for example, a drum, disc or jaw brake. The brake may e.g. be hydraulically or mechanically operated. The brake may comprise brake shoes which have two projections which, upon actuation of the brake, simultaneously come into contact with the respectively adjacent part, for example with the said projection, and thus develop an optimal braking effect.

Figur 1 zeigt in einer perspektivischen Darstellung ein Gittertragwerk bzw. ein Gittertragwerksegment in einer ersten Ausführungsform der vorliegenden Erfindung. Das Gittertragwerk besteht aus in Längsrichtung verlaufenden Gitterstäben 10, 10', die durch verbindende Gitterstäbe 20, 30, 50 miteinander in Verbindung stehen. Dabei sind die verbindenden Gitterstäbe 20, 30, 50 in den Außenflächen des ausgefalteten Gittertragwerkes angeordnet, wohingegen die in Längsrichtung verlaufenden Gitterstäbe 10, 10' die Kanten bzw. im Querschnitt die Ecken des Gittertragwerkes bilden.Figure 1 shows a perspective view of a lattice structure or a lattice support structure segment in a first embodiment of the present invention. The lattice support structure consists of longitudinally extending bars 10, 10 ', which communicate with each other by connecting bars 20, 30, 50. In this case, the connecting bars 20, 30, 50 are arranged in the outer surfaces of the unfolded lattice support structure, whereas the longitudinally extending bars 10, 10 'form the edges or in cross-section the corners of the lattice support structure.
Gemäß Figur 1 bilden die Gitterstäbe 10 feststehende Gitterstäbe, das heißt Gitterstäbe, die beim Ein- und Ausfalten des Gittertragwerkes ortsfest verbleiben, das heißt sich nicht bewegen. Die Gitterstäbe 10' sind beim Ein- und Ausfalten relativ dazu beweglich.According to Figure 1, the bars 10 are fixed bars, that is, bars, which remain stationary during insertion and removal of the lattice support structure, that is, do not move. The bars 10 'are relatively movable during insertion and removal.
Die verbindenden Gitterstäbe 20, 30 sind jeweils derart ausgeführt, dass sie in ihrem einen Endbereich schwenkbar, jedoch ortsfest an jeweils einem der in Längsrichtung verlaufenden Gitterstäbe 10, 10' angeordnet sind um ihre in ihrem anderen Endbereich über eine Gleithülse 20', 30' verschieblich relativ zu dem anderen, vorzugsweise zu einem benachbarten in Längsrichtung verlaufenden Gitterstab 10, 10' angeordnet sind. Die verbindenden Gitterstäbe 20, 30 sind vorzugsweise schwenkbar an diesen Gleithülsen 20', 30' angeordnet.The connecting bars 20, 30 are each designed such that they are pivotally mounted in their one end, but fixed to each one of the longitudinally extending bars 10, 10 'are arranged around their in their other End region via a sliding sleeve 20 ', 30' displaceable relative to the other, preferably to an adjacent longitudinally extending grid bar 10, 10 'are arranged. The connecting bars 20, 30 are preferably pivotally mounted on these sliding sleeves 20 ', 30'.
Wie dies weiter aus Figur 1 hervorgeht, existieren weitere, die in Längsrichtung verlaufenden Gitterstäbe 10, 10' verbindende Gitterstäbe 50, die im ausgefalteten Zustand des Gittertragwerkes senkrecht zur Längsrichtung des Gittertragwerkes verlaufen. Diese verbindenden Gitterstäbe 50 bzw. Verbindungsstreben weisen ein Gelenk auf, über das sie in die dargestellte Position ausgeschwenkt oder relativ dazu auch eingeschwenkt wird, so dass die Schenkel der Gitterstäbe 50 im Winkel zueinander verlaufen.As is further apparent from Figure 1, there are further, the longitudinally extending bars 10, 10 'connecting bars 50 which extend in the unfolded state of the lattice support structure perpendicular to the longitudinal direction of the lattice support structure. These connecting bars 50 or connecting struts have a joint, via which it is swung out into the position shown or is also pivoted in relative thereto, so that the legs of the bars 50 extend at an angle to each other.
Wie dies schließlich weiter aus Figur 1 hervorgeht, sind Stangen 60 vorgesehen, die die in Längsrichtung voneinander beabstandeten verbindenden Gitterstäbe 50 miteinander verbinden. Auf diese Weise ist es möglich, durch Betätigung dieser Stangen 60 ein Einfalten bzw. Ausfalten des Gittertragwerkes zu bewirken. Diese Stangen 60 können motorisch, pneumatisch, hydraulisch oder auf sonstige Weise beispielsweise auch manuell angetrieben werden.As will be seen finally in Figure 1, rods 60 are provided which connect the longitudinally spaced interconnecting grid bars 50 together. In this way, it is possible to cause folding or unfolding of the lattice support structure by actuation of these rods 60. These rods 60 can be driven by motor, pneumatically, hydraulically or otherwise manually, for example.
Mit dem Bezugszeichen 70 ist eine Verbindungsstrebe gekennzeichnet, die ebenfalls gelenkig verschwenkbar ist und die die Aufgabe hat, das Gittertragwerk im ausgefalteten Zustand zu sichern. Diese Strebe 70 erstreckt sich diagonal zwischen zwei in Längsrichtung verlaufenden Gitterstreben 10', wie dies aus Figur 1 hervorgeht.By the reference numeral 70, a connecting strut is characterized, which is also pivotable articulated and has the task to secure the lattice structure in the unfolded state. This strut 70 extends diagonally between two longitudinally extending lattice struts 10 ', as is apparent from Figure 1.
Figur 2 zeigt ein Gittertragwerk bzw. Gittertragwerksegment, das sich von dem in Figur 1 dargestellten Gittertragwerk dadurch unterscheidet, dass es im Querschnitt polygonal ausgeführt ist. In diesem Fall handelt es sich um eine sechseckige Struktur, deren Kanten durch in Längsrichtung verlaufende Gitterstäbe 10, 10' gebildet werden. Wie auch in Figur 1 wechseln sich in Längsrichtung verlaufende feststehende Gitterstäbe 10 mit in Längsrichtung bewegbaren Gitterstreben 10' ab. Wie dies weiter aus Figur 2 hervorgeht, sind in einem Endbereich des Gittertragwerkes verbindende Gitterstäbe 80, 90 vorgesehen, die jeweils drei der in Längsrichtung verlaufenden Gitterstäben 10 bzw. 10' miteinander verbinden. Dabei verbindet das Gestänge 80 die drei feststehenden Gitterstäbe 10 und das Gestänge 90 die drei bewegbaren Gitterstäbe 10'.Figure 2 shows a lattice support structure or lattice support structure segment, which differs from the lattice support structure shown in Figure 1 in that it is designed polygonal in cross section. In this case, it is a hexagonal structure whose edges are formed by longitudinal bars 10, 10 '. As in FIG. 1, fixed grid bars 10 extending in the longitudinal direction alternate with grid bars 10 'which can be moved in the longitudinal direction. As is further apparent from Figure 2, connecting bars 80, 90 are provided in an end region of the lattice support structure which connect three of the longitudinally extending lattice bars 10 and 10 'to one another. In this case, the linkage 80 connects the three fixed bars 10 and the linkage 90, the three movable bars 10 '.
Figur 3 zeigt ein Gittertragwerk, das aus zwei der Gittertragwerksegmente gemäß Figur 2 besteht. Diese sind in ihren Endbereichen über die in Längsrichtung verlaufenden Gitterstäbe 10, 10' miteinander verbunden.FIG. 3 shows a lattice support structure, which consists of two of the lattice support structure segments according to FIG. These are connected in their end regions via the longitudinally extending bars 10, 10 'with each other.
Aus Figur 4 sind weitere perspektivische sowie Seitenansichten des Gittertragwerkes gemäß Figur 2 ersichtlich. Die Figuren 4a und 4b zeigen das Gittertragwerk in Seitenansichten. Aus den Figuren 4c und 4d ergeben sich perspektivische Ansichten des Gittertragwerkes gemäß Figur 2 und Figur 4d zeigt eine Querschnitts- bzw. Draufsicht auf das Gittertragwerk, aus der sich die polygonale Struktur des Gittertragwerkes ergibt.FIG. 4 shows further perspective as well as side views of the lattice support structure according to FIG. 2. Figures 4a and 4b show the lattice structure in side views. FIGS. 4c and 4d show perspective views of the lattice support structure according to FIG. 2, and FIG. 4d shows a cross-sectional or plan view of the lattice support structure, from which the polygonal structure of the lattice support structure results.
Figur 5 zeigt eine weitere Ausgestaltung der Gittertragwerkes gemäß der vorliegenden Erfindung. Ein Unterschied zu der Ausführungsform gemäß Figur 1 liegt insbesondere darin, dass die verbindenden Gitterstäbe 20, 30 über Kreuz verlaufen, wie dies aus Figur 5 hervorgeht. Die über Kreuz verlaufenden Gitterstäbe 20, 30 sind jeweils in ihrem einen Endbereich schwenkbar an einem der Gitterstäbe 10 bzw. 10' und in ihrem anderen Endbereich schwenkbar an einer Gleithülse 20'. 30' angeordnet, die verschieblich auf einem der in Längsrichtung verlaufenden Gitterstäbe 10, 10' verläuft.FIG. 5 shows a further embodiment of the lattice support structure according to the present invention. A difference from the embodiment according to FIG. 1 lies in particular in that the connecting bars 20, 30 run crosswise, as can be seen from FIG. The cross-extending bars 20, 30 are each pivotable in one end portion of one of the bars 10 and 10 'and in its other end portion pivotally mounted on a sliding sleeve 20'. 30 'which slidably extends on one of the longitudinally extending bars 10, 10'.
Figur 6 zeigt eine weitere Ausführungsform der vorliegenden Erfindung, bei der der Kreuzungspunkt der verbindenden Gitterstäbe 20, 30 nicht im Bereich eines der in Längsrichtung verlaufenden Gitterstäbe liegt, wie dies aus Figur 5 ersichtlich ist, sondern in etwa mittig auf der Außenfläche des Gittertragwerkes. Aus Figur 6 ist ferner ein Gestänge ersichtlich, das aus Stangen 120 besteht, die jeweils an einer der in Längsrichtung verlaufenden Gitterstäbe 10, 10' angreifen und zu einem gemeinsamen Verknüpfungspunkt 130 zusammenlaufen. Die Stangen 120 weisen somit die Struktur eines Pyramidenstumpfes auf, wobei wie dies aus Figur 6 weiter hervorgeht, zwei derartige Pyramidenstümpfe versetzt zueinander aneinander grenzen. Diese Gestänge 120 dienen dazu, durch Betätigung des Verknüpfungspunktes ein Einfalten bzw. Ausfalten des Gittertragwerkes zu bewirken.FIG. 6 shows a further embodiment of the present invention, in which the point of intersection of the connecting bars 20, 30 does not lie in the region of one of the longitudinal bars, as shown in FIG. 5, but approximately in the center of the outer surface of the grid. From Figure 6, a linkage is further seen, which consists of rods 120, each attacking on one of the longitudinally extending bars 10, 10 'and converge to a common point of connection 130. The rods 120 thus have the structure of a truncated pyramid, wherein, as is further apparent from FIG. 6, two such truncated pyramids adjoin one another offset from one another. These linkages 120 serve to effect folding or unfolding of the lattice structure by operation of the connection point.
Figur 7 zeigt eine weitere Ausführungsform eines Gittertragwerkes gemäß der vorliegenden Erfindung. Wie dies aus Figur 7 im einzelnen hervorgeht, sind die verbindenden Gitterstäbe 20, 30 untereinander sowie mit den weiteren verbindenden Gitterstäben 50 gelenkig beispielsweise über eine Bolzenverbindung miteinander verbunden. Beim Einfalten oder Ausfalten des Gittertragwerkes werden die verbindenden Gitterstäbe 20, 30 um den Kreuzungspunkt 150 verschwenkt und gleichzeitig werden die verbindenden Gitterstäbe 50 um ihr Gelenk verschwenkt, das mit dem Kreuzungspunkt 150 fluchtet und mit diesem in geeigneter Weise verbunden ist.FIG. 7 shows a further embodiment of a lattice support structure according to the present invention. As can be seen in detail from FIG. 7, the connecting bars 20, 30 are interconnected with one another and with the further connecting bars 50, for example via a bolt connection. When folding or unfolding the lattice support work, the connecting bars 20, 30 are pivoted about the crossing point 150 and at the same time the connecting bars 50 are pivoted about their joint, which is aligned with the intersection point 150 and connected to this in a suitable manner.
Figur 8 zeigt eine weitere Ausgestaltung eines Gittertragwerkes, das eine im Querschnitt dreieckige Struktur aufweist.FIG. 8 shows a further embodiment of a lattice support structure which has a triangular cross-section structure.
Figur 9 zeigt weitere Ansichten dieses Gittertragwerkes. Dabei zeigen Figuren 9a und 9b Seitenansichten und die Figuren 9c und 9d perspektivische Ansichten des Gittertragwerkes bzw. Gittertragwerksegmentes.FIG. 9 shows further views of this lattice support structure. FIGS. 9a and 9b show side views and FIGS. 9c and 9d show perspective views of the lattice support structure or lattice structure segment.
Die Gittertragwerke bzw. Gittertragwerksegmente gemäß der vorliegenden Erfindung dienen als Strukturelemente für unterschiedlichste Einsatzzwecke, beispielsweise als Gerüste, Tragstrukturen, Bestandteile von Kranen, etc. The lattice structures or lattice support structure segments according to the present invention serve as structural elements for a wide variety of purposes, such as scaffolding, support structures, components of cranes, etc.
