Definitions
- the present invention relates to a lattice support structure with interconnected bars, wherein the lattice support 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 of in the longitudinal direction of the lattice support running lattice bars during folding of the lattice support structure can be reduced and enlarged during the unfolding of the lattice support structure.
- lattice structures of the beginning known type in which the surrounded by the lattice structure interior for other functions, such as stairs, elevators, etc. is available.
- sleeves on which the connecting bars are arranged, run on the longitudinally extending bars. If the lattice structure is folded or unfolded, the sliding sheaths accordingly shift on the lattice bars extending in the longitudinal direction of the lattice structure until the lattice structure has reached its desired final position.
- the present invention has the object of developing a lattice support structure with the features mentioned in such a way that its structure is simplified compared to a previously known lattice structure.
- a lattice support structure according to the preamble of claim 1, characterized in that at least one, preferably all of the connecting bars are not slidably disposed on the longitudinally extending bars, but are pivotally arranged on these.
- bars exist, which are pivotally mounted on a grid bar, which in turn is pivotally connected to one of the longitudinally extending bars in combination.
- a lattice support structure is provided with interconnected bars, wherein the lattice structure in the longitudinal direction of the lattice support running lattice bars and these directly or indirectly connecting bars has, wherein the connecting bars are in communication with the longitudinally extending bars such that the distance of the running in the longitudinal direction of the lattice support bars when folding the lattice support structure is reduced and enlarged during unfolding of the lattice structure, wherein one, several or all of the connecting bars pivotally at a fixed position on the longitudinal bars or at a fixed position of more connecting bars are arranged, which in turn are arranged at a fixed position pivotally mounted on the longitudinally extending bars.
- At least one of the connecting bars has a first length when the lattice support structure is folded out and has a second length when the lattice support structure is folded, wherein the first length is greater than the second length.
- the change in length of the bars can for example take place in that they have in a first end region via a pivot lever which is pivotally connected to a running in the longitudinal direction of the lattice support structure grid bar. In the pivoted state of the pivot lever, the length of the grating bar is comparatively small, in the pivoted state of the pivot lever comparatively large.
- the connecting bars in the end region in which the pivot lever is arranged a receptacle, preferably a groove-shaped receptacle, in which the pivot lever is at least in a distance receivable.
- the connecting bars are in the outer surface or the outer surfaces of the lattice support structure.
- the extending in the longitudinal direction of the lattice support structure bars can form the outer edges of the lattice support structure.
- lattice structure which is square or rectangular in section, whose corner regions are formed by the lattice bars running in the longitudinal direction and between which the connecting lattice bars extend.
- the invention is not limited to this, because other cross-sectional shapes of the lattice support structure are conceivable.
- the lattice structure may have a longitudinally repeating structure of the connecting lattice bars. It is conceivable, for example, that in each case two connecting lattice pieces run crosswise and that this cross-like arrangement is repeated in the longitudinal direction of the lattice support structure.
- connecting struts are present, which extend in the unfolded state of the lattice support structure perpendicular to the longitudinal direction of the lattice support structure from one to another extending in the longitudinal direction of the lattice support structure bars. These connecting struts serve to increase the stability of the lattice support structure.
- connecting struts can have at least one joint, by means of which they are adjustable between a folded and a folded state. It is conceivable that the connecting struts are spaced in the longitudinal direction of the lattice support structure and communicate with each other. In this way it becomes possible, for example, by actuating one of the connection aspire to further connecting struts, which are associated with this, also to operate. This may be necessary, for example, to effect the folding of the lattice structure or to lock the lattice structure in the unfolded state.
- locking means are provided, by means of which the connecting struts and / or the connecting bars are fixable in at least one position.
- the locking means will be arranged so as to secure the lattice structure in the unfolded state.
- 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 13, wherein the lattice 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 grating 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 can be provided where two segments of a grid bar are pivotally connected to 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.
- 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 can be actuated hydraulically or mechanically, for example.
- 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 in the unfolded state
- FIG. 2 a perspective view of the lattice support structure in the folded-in state
- FIG. 3 shows a perspective view of the lattice support structure according to FIGS. 1 and 2 in different views and with a detailed view.
- FIG. 4 shows a perspective view of a lattice support in the unfolded state in a further embodiment
- Figure 5 a perspective view of the lattice support structure according to Figure 4 with different views and detail views.
- FIG. 1 shows by reference numeral 10 four bars extending in the longitudinal direction of the lattice structure, which are arranged in such a way that they form the four corners of a square in a cross-sectional view of the lattice support structure. Shown is a lattice support structure segment. Through a suitable connection z. B. by a bolt connection several such segments can be joined together. As can be further seen from FIG. 1, two bars 10 are connected by a plurality of connecting bars 20, 30, with two bars 20, 30 each running crosswise, as can be seen from FIG. This cross-like arrangement is continued in the longitudinal direction of the lattice structure, as is also apparent from Figure 1.
- the connecting bars 20, 30 form the four outer sides of the latticework shown, whereas the bars 10 form the corner areas.
- Dividing the illustrated structure mentally in three longitudinally successive segments shows that each segment has substantially the same arrangement of longitudinally extending bars 10 and connecting bars 20, 30.
- Per segment four longitudinally extending bars 10 and eight connecting bars 20, 30 are provided, wherein each two of the connecting bars 20, 30 lie in an outer side of the segment and thus also of the lattice support structure.
- the bars 20, 30 are not arranged in sliding sleeves on the longitudinally extending bars 10, but that they are more directly or indirectly connected via hinge points with these.
- the hinge points are fixed in the illustrated embodiment.
- each of the connecting bars 20, 30 has a pivoting lever 40 in one of its end areas.
- This pivot lever 40 is on the one hand pivotally connected to the remaining portion of the grid bar 20, 30 and on the other hand pivotally with the longitudinal direction of the lattice support structure extending grid bar 10 in conjunction.
- the connection between the pivot lever 40 and the other part of the grid bar 20, 30 is such that the pivot lever 40 can be folded, which of course reduces the total length of the connecting grid bar 20, 30.
- the pivot lever 40 are deployed, ie all connecting bars 20, 30 take their maximum length.
- the connecting bars 20, 30 in the adjacent section on a groove-shaped receptacle 22, 32, in which the pivot lever 40 can be at least partially received in the folded state of the lattice structure, as can be seen for example in FIG.
- the connecting bars 20, 30 have a further recess 24, 34, in which in the folded state of the lattice support structure of the portion of the pivot lever 40 which is pivotally connected to the extending longitudinally extending bar 10 in connection.
- the lattice structure also has connecting struts 50 which lie in a direction perpendicular to the longitudinal direction of the lattice support work plane.
- the connecting struts 50 each connect two of the longitudinally extending bars 10. As can be seen from Figure 1, the connecting struts 50 thus form the sides of a square, as long as the lattice support structure is in the unfolded state. In this state, the connecting struts 50 are straight.
- connecting struts 50 or the groups of connecting struts 50 are arranged spaced apart from one another in the longitudinal direction. They are collapsible via at least one joint such that the parts of the connecting struts extend in the folded state substantially in the longitudinal direction of the lattice support structure.
- connecting elements 52 are provided, each connecting two longitudinally adjacent connecting struts 50 together.
- locking means which lock the connecting struts 50 in the position shown and in this way prevent the lattice structure unintentionally collapses.
- connecting elements can be provided which prevent the pivot levers 40 from being pivoted in, which means in other words that the bars 20, 30 maintain the spacing of the connecting longitudinal bars 10. It is also conceivable to make the locking by the fact that the connecting bars 20, 30 at its end, where they do not have a pivot lever 40, can be locked. Finally, a lock is also conceivable in the point of intersection of the bars 20, 30. It is possible to use clamping pieces or bolts or the like which prevent the positions of the bars 20, 30 from each other from changing.
- FIG. 2 shows, as stated above, the arrangement according to FIG. 1 in a folded position
- FIG. 3 again shows different representations of the lattice support structure according to FIG. 1 and according to FIG. 2. It becomes clear from FIGS. 3 a, 3 b and 3 c that the connecting ones are in the same position Height and on one side of the lattice structure located, connecting bars 20, 30 run crosswise.
- the lattice support structure forms a square construction in cross-section or in plan view, whose corners are formed by the longitudinally extending bars 10.
- FIG. 3d shows the detail B according to FIG. 3b. From this figure it is again clear that the bars are designed in one of their end portions with a pivot lever which is pivotally connected to the adjacent region of the grid bar and with the longitudinally extending grid bar 10 in connection. In contrast, the adjacently hinged grid bar 30 is not executed in the end region shown here with a pivot lever. The articulation of the bars 20, 30 on the grid bar 10 takes place approximately or exactly at the height at which the connecting element 50 is arranged.
- FIG. 4 shows the arrangement of a lattice support structure according to the invention of a further embodiment. This corresponds essentially to the embodiment of FIG. 1, but with the difference that some of the connecting bars 20, 30 are not directly but only indirectly connected to the longitudinally extending bars 10.
- FIG. 5 shows the lattice support structure according to FIG. 4 in different perspective and detailed views.
- the basic structure of the lattice support structure consists of four longitudinally extending bars 10 on which these connecting girder bars 20, 30 are arranged directly or indirectly. As can be seen from FIG. 5g, it also applies to this lattice support structure that it has a rectangular cross-section.
