Definitions
- the present invention relates to a lattice support structure having interconnected grid bars, the grid bars communicating with each other such that the lattice structure is foldable and unfoldable.
- Such lattice structures are known from the prior art. They may, for example, serve as support structures, which have the advantage that in the unfolded state, i. H. represent a resilient and mechanically stable structure in their operating position. Another advantage of this lattice structures is that they take comparatively little space in the folded state and therefore can be well stored and transported.
- Lattice structures known from the prior art consist, for example, of bars extending in the longitudinal direction of the lattice support structure, which bars are connected to one another by connecting bars, the connecting bars communicating with the longitudinal bars stand that the distance of the extending 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.
- the present invention has the object of developing a lattice support structure of the type mentioned in such a way that its applications are extended.
- the present invention is thus based on the finding that the lattice support structure can serve, for example, for evacuating persons from a burning building or the like.
- These evacuation means may be designed, for example, as a conductor or the like.
- the lattice structure for example, be firmly mounted on a building or the like and, if necessary, d. H. be unfolded in an emergency to allow the evacuation of persons. If the lattice support structure is not required for this purpose, it may be arranged in the folded state on the house and take up comparatively little space in this state.
- the lattice structure is not permanently associated with a building or the like, but in case of emergency is spent on site and built or folded out there.
- the lattice support structure consists of several lattice tower segments that can be added together in the longitudinal direction in order to achieve a sufficient height of the lattice support structure.
- the connection of the individual segments can be done for example by a bolt connection or the like.
- the at least one conductor may be arranged on at least one of the longitudinally extending grid bars of the lattice support structure.
- each of the longitudinally extending bars of the lattice support structure is assigned a respective ladder. However, this is not absolutely necessary.
- the evacuation means comprise at least one conductor and at least one fall protection associated with the ladder, in particular a linkage that at least partially surrounds the space occupied by a person located on the ladder.
- This fall protection can, for example, be arranged pivotably on the lattice support structure or also on the conductor or on the other evacuation means and be swung out if necessary, so that the aforementioned fall protection is realized.
- the evacuating means do not necessarily have to be formed by ladders. In principle, any other evacuating means, such as rods, scaffoldings, railings, etc., come into consideration.
- the evacuation means have at least one transition which protrudes from the lattice support structure in at least one position or connects different positions of the lattice support structure with one another.
- the transition can be used to allow the persons, for example, from a building to be evacuated the transition to the lattice structure and thus also to the other provided there evacuation, such as ladders.
- the transition enables the transition from one position of the lattice structure to another position of the lattice structure.
- the transitions for example, to the Outside of the lattice structure or through the interior of the lattice structure run. In this case, they can serve to distribute the persons to be evacuated evenly to the evacuation means, for example to several ladders of the lattice structure.
- transition in at least one position extends perpendicularly or obliquely from or in the lattice support structure, so that the persons to be evacuated easily reach the lattice support structure or can run from one position of the lattice support structure to another position.
- the transition extends in at least one position of the lattice support structure parallel to the lattice support structure. In this case, the transition takes up very little space, since it applies, for example, for transport or storage purposes to the lattice structure.
- the connecting bars may be located on the outer surface or the outer surfaces of the lattice support structure.
- the grid bars running in the longitudinal direction of the lattice support structure can form the outer edges of the lattice support structure.
- the lattice support structure in cross section rectangular, square, triangular, polygonal or the like can be performed.
- the lattice support structure has a repeating structure in the longitudinal direction of longitudinally extending bars and connecting bars.
- At least a portion of the connecting bars may be formed by connecting struts extending in the unfolded state of the lattice structure from one to another of the lattice bars extending in the longitudinal direction of the lattice support structure. It can be provided that the connecting struts have at least one joint by means of which they are adjustable between a folded and a folded state.
- locking means by means of which the connecting bars can be fixed in at least one position. In this way it is ensured that the lattice structure in the unfolded state remains in this position and does not collapse unintentionally.
- means are provided which act on at least two of the connecting and / or extending in the longitudinal direction of the grid bars such that the distance of the bars to each other can be increased or reduced, whereby the lattice structure unfolds or unfolds.
- the lattice structure has at least two structural segments, which are designed to be telescopic to each other. In this way it is possible to achieve the desired height of the entire supporting structure in a particularly simple manner. In this case, two or more than two mutually telescoping structural segments can be provided. It is conceivable to unfold the structural segments after Austeleskopieren and then connect to the structural segments from which they were telescoped out. In this way, a basically any height of the lattice support structure can be achieved.
- 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 18, wherein the lattice structure has pivotally arranged bars, wherein the pivotable connection is designed such that one of the pivotally connected to each other. bonded 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.
- 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 a plurality of bars together or to provide bars of different lengths. In principle, it is also conceivable to carry out both ends of the lattice bar with grooves or with the said projections.
- a brake or a fixing device 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.
- FIG. 1 shows a perspective view of the lattice support structure according to the invention in the unfolded state
- Figure 2 a perspective view of the lattice support structure according to the invention in the folded state
- Figure 3 different embodiments of the lattice support structure according to the invention in the unfolded state.
- Figure 1 shows a perspective view of a lattice structure according to the present invention.
- This consists of longitudinally extending bars 10, which are arranged such that they form the corners of a rectangle or square of the structural cross-section. Between these bars 10 struts 50 extend, which have a joint by means of which the struts 50 can be pivoted or swung out.
- connecting struts are pivotally connected on both sides with two bars 10 in combination.
- connecting bars 20, 30 are provided, which are each arranged in one end region pivotally connected to one of the bars 10 and in the other end area via a sliding sleeve 20 ', 30' on a further, preferably adjacent grid bar 10. If the lattice support structure is to be unfolded from the position shown in FIG. 2, the connecting struts 50 are moved via the linkage 60 into their position shown in FIG. 1, with the result that the lattice bars 10 extending in the longitudinal direction are moved apart and the lattice support structure unfolds ,
- this linkage 65 can be swung out in such a way that it provides fall protection for the person on the ladder 40.
- This fall protection is formed by part-circular segments which are pivotally mounted on the conductor 40 and which in turn are connected by extending in the longitudinal direction and parallel to the conductor 40 rods. In this way, a fuse for the person located on the conductor 40 is formed.
- Reference numeral 70 denotes a transition or step, which is likewise arranged pivotably on the conductor 40, as can be seen, for example, from FIG. 1 and also from FIG. Figures 1 and 2 show the state of the transition 70 in the pivoted state, in which the transition parallel to the fall protection or to the linkage 60 and to the conductor 40 extends.
- the transition 70 is swung so that it runs horizontally and preferably such that it is perpendicular to the lattice support structure or to the conductors 40 and thus also to the longitudinally extending bars 10. This can be seen, for example, from FIG. 3c.
- the transition 70 which has a railing, persons from a building to be evacuated or the like can safely reach one of the ladders 40 of the lattice support structure and descend via the ladder 40.
- a lattice support structure segment is shown that such an overlay gear 70 has. In principle, it is likewise conceivable to provide several such transitions 70 per lattice frame segment.
- FIG. 3a and FIG. 3b show the arrangement according to FIG. 3c in a side view and FIG. 3d in a view from above.
- each one or more of the conductors 40 is associated with a fall protection and / or a transition.
- the lattice support structure or the illustrated lattice support structure segment is designed to be connected to further identical or else differently constructed lattice structures or structural elements. Serve in the end region of the extending in the longitudinal direction of the bars 10 connecting means. It is thus conceivable to connect two or more of the lattice structures illustrated in FIGS. 1, 2 and 3 to one another and thus to provide a lattice support structure of the desired height.
- a lattice support structure could be accommodated in the interior of the lattice support structure shown in FIG. 1 and, if necessary, telescoped out, if necessary, and unfolded and connected to the illustrated lattice support structure after the telescoping.
- the invention is not limited to telescoping lattice structures, but also includes lattice structures, in which the individual segments are put together before or after unfolding and then connected, and lattice structures, which consist only of one of the segments shown.
