Description

Cover device with continuing cover plates

The invention relates to a cover device with in the use position in a common plane and in at least one row continuing cover plates, which partially overlap in their mutual edge-side contact area.

Such covers are known in many forms and for various applications. For example, such covers are known as balcony floors or as roofing over balconies or as roofing of carports and so on.

In many cases, it is important that the contact point of two cover plates is rainproof, so that rain or other precipitation no water can get into the area under this cover.

In practice, it has been found that such a rain impermeability can not always or not sufficiently be achieved by a mutual overlap of edges or edge pieces, in particular if the cover plates give way during loading or when walking and / or deformed.

It is therefore the object to provide a cover of the type defined, which is at least largely rainproof, even if deformations occur, for example, by stress or the production and / or assembly are less precise.

This object is achieved with the means and features of claim 1.

CONFIRMATION COPY In particular, it is provided to solve the problem that mutually parallel, mutually spaced edges on a respective cover plate for a mutual rain-th overlap are formed differently and at a first edge of the top of the cover plate continuing web and below this web a gutter is arranged whose one edge is connected tightly with the cover plate having it and is offset from the free edge of the web and whose other edge is designed as a free edge, which engages in the position of use an edge web of the neighboring cover plate at a distance. The gutter preferably belongs to the mentioned first edge, but could also be provided on the other edge cooperating therewith in the position of use.

If, therefore, precipitation or rainwater penetrates into the contact area of two cover plates formed in this way, this passes into the "gutter" located under this upper-side contact area and is collected and discharged therefrom, in particular if this channel runs at a slight angle at the same time.

It is expedient if, at the second edge of the cover plate, in continuation of its upper side, the edge-side web is provided as the upper free edge, which is laid at least partially lower relative to the upper side by the thickness of the web of the adjacent plate located on the first edge that in the position of use of the web of the first edge of a cover plate engages beneath this second web of the other edge of the adjacent cover plate or if the web is optionally set so deep in the ers ^¬ th edge that in the use position of the web on the second edge of the web of first edge of a neighboring plate overlaps.

The mutual over or under reaching the use of the tops of the adjacent cover plates continuing webs thus creates a gapless continuation that may already be largely dense, but could pass rainwater into the underlying gutter due to minor bumps or impurities. Thus, the combination of overlapping webs with the gutter for the desired rain tightness is favorable.

In this case, it is advantageous for the least possible rain-permeability if the near-surface edge-side webs of at least two continuing cover plates in the use position contact each other at least in regions in a planar or lenticular manner.

An even further improvement of the rain impermeability, especially in the case of heavy rain, can be achieved if a second deeper collecting channel for rainwater is provided in the contact area of the two edges of two cover plates, which is provided in particular on that edge of the cover plate, which leads to the edge with the first gutter runs parallel and spaced. This means that both spaced parallel edges can each have one of the gutters, which can catch in the position of use possibly through the upper contact of the edge webs penetrating rainwater, the second, in use position deeper gutter can absorb the water, which at the upper gutter overflows.

A particularly advantageous embodiment of the invention concerning the mutual contact and attachment of two Ab- Cover plates may consist in that a cover plate is provided on the parallel, differently shaped edges facing away from each other and thus a clamping connection is provided at the edges of two such cover plates which are in contact with each other in use position. Accordingly, the cover plates keep within the cover their position, even if the clamping connection has a sliding seat, so a mutual adjustment against the frictional force allowed. It is advantageous if at the in use position facing each other and touching edges of two continuing cover plates at a distance below the top facing each other clamping webs - opposite the edges with their cross sections - projecting overlap in the position of use and touch clamping. This not only improves the mutual connection, but also the edge area of touching cover plates are stiffened.

The distance of the free edge of the web extending above the first rain gutter from the free edge of this gutter can be dimensioned so that the web projecting in the region of the upper side of the other edge of a neighboring cover plate can be inserted at least obliquely into this clearance and space the use position can be pivoted. As a result, the mutual assembly of continuing cover plates for assembling a covering device is simplified, since the cover plates to be brought into mutual contact position do not have to be aligned with one another in order to be able to be fitted together. Thus, despite the gutter located below the upper-side webs, they can be securely joined together and brought into a mutually aligned position.

Helpful for a space-saving yet secure connection of cover plates to form a covering it may be, if before joining the at least two in use position continuing cover plates of the clear distance between the above the first gutter arranged, free-ending web and the lower relative to the upper side associated terminal web of the same edge of the cover smaller than the outer distance between the overlapping in use position upper web and the second clamping bar on the second edge of the neighboring cover plate and when the first mentioned free-ending bridge and located on the same edge clamping bar in the position of use, the webs of the neighboring cover plate in its intermediate space clamped ,

This arrangement allows the mutual clamping connection flush with each other continuing cover plates and yet the fact that the one cover plate initially introduced obliquely with its upper web in the space between the upper web of the neighboring plate and the free edge of the upper gutter and then in their position of use is pivoted, in which case the clamping webs come together and finally engage behind clamping. Thus, the desired clamping connection is made possible, but without the plates already having to mate in mutually aligned position, which would require correspondingly more mounting space.

At least one of the clamping webs or both in contact position contacting clamping webs of interconnected and continuing cover plates may have an adjacent to the clamping point arranged curved cross-section, wherein the curvature of the one clamping web is remote in the use position of the other clamping web. As a result, the mutual pushing together at the last moment of pivoting of a cover plate in the other and in the position of use is facilitated Tert, since the curved edges favor the gradual assembly, wherein instead of a curvature and one or more bevels may be provided. The one or more curved edges of the clamping webs can thus act as skids on the respective counter-clamping web and slide each other in their final position of use.

The two in use position each other at least at the top of the cover overlapping, free-ending webs and accordingly the lower lying clamping webs can be displaceable relative to each other in the orientation direction of the cover plates transversely to the edges to be joined and the displacement can be limited by at least one stop. Due to this mutual displaceability of the cover plates while the rain impermeability remains constant, assembly inaccuracies and / or thermal expansions can be absorbed or compensated.

It may be advantageous if the displacement of the touching cover plates limiting stop a lower deckle of a cover plate and in the use position thus preferably flush lower deckle the be ^¬ adjacent cover plate. So if the cover plates are pushed together to the stop, the underside is practically optically closed.

The counter-stop to limit the displacement of the two cooperating in the use position and connected cover plates may be the one boundary of the second gutter. Thus, this located opposite the top in the use position deeper collecting gutter as close as possible to the adjacent cover plate and touches them when pushed together cover plates with their limitation. The lower second gutter can be subdivided by a web which is upstanding in the use position and / or divided according to its fastening side, and the edge-free part of this gutter can be provided for receiving water which exceeds the separating wall. So if rainwater penetrates through the upper gutter into the lower region of the lower gutter, this rainwater can first accumulate at the aforementioned elevated web, but then also enter the near-edge part of this gutter when the amount of water exceeds the mentioned bridge.

By skillful dimensions concerning the arrangement of the second, in use position deeper collecting gutter and the clamping webs according to claim 14, the already mentioned closed bottom of the entire covering can be favored.

Further embodiments of the covering device according to the invention can be found in the claims 15 to 19.

Claim 15 indicates features by which the cover plates and thus the cover obtained such strength and rigidity that they can be at least co-supporting or even self-supporting. Thus, in the majority of cases, no substructure is required for the covering device according to the invention and it can be statically integrated at its point of use. Claim 16 contains dimensional relationships, which relates to a convenient mutual overlap of the cross sections of the upper webs touching cover plates and favors the impermeability to rain and the mutual stabilization. The stiffening webs which are arranged between an upper and a lower level or layer of a respective cover plate and have already been mentioned in claim 15 can run parallel to the edges of the cover plates that contact one another in the position of use and overlap in regions. The resulting reinforcement is correspondingly effective.

Moreover, it is possible by the arrangement of the stiffening webs parallel to one another and to the edges in contact with the use that the cover plates made of aluminum or an aluminum alloy and / or plastic and in particular are extruded. Practically, this allows almost any longitudinal expansion in the direction of the contacting edges and this stiffening webs.

The cover plates are expediently formed at right angles according to claim 19 and their four boundaries form a rectangle, wherein the rain-tight overlapping edges in the use position expediently the longer edges, so the longitudinal edges of this rectangle.

This too is favored in particular by an extrusion-producing process. Furthermore, this results in cover plates, which can have the great linear expansions, that is, for example, can form the surface of a balcony or its upper roof, with only such cover plates extending parallel to the wall of the house touching at the edges, while the ends at the same time touch the ends of this bal - can form roofing.

The length of the longitudinal edges of the cover plates can therefore be a multiple or a multiple of the length of perpendicular thereto arranged transverse edges amount.

Especially when combining one or more of the above-described features and measures results in a Abdeckvor- direction, which can be mounted largely without support structures of their course, yet rainproof and even with thermal movements or the like remains rainproof, but at the same time also easy to manufacture and assemble. For example, a sloping roofing be formed by such cover plates that a running at the highest point of this oblique roofing transverse to the slope of this roof cover plate, then the next deeper is pivoted therein and brought into alignment position and so on until the cover the whole sloping area as a roof and, due to its impermeability to rain, protect a room underneath against rainwater.

In the following description of the various embodiments obtained in their function matching parts even with different configuration matching reference numerals.

In the position for use according to FIG. 1, a covering device designated as a whole by 1 is composed in a common plane and in at least one row of continuing cover plates 2 which partially overlap in their mutual, edge-side contact region 3. On a generally designated 4 balcony three different applications of such a cover device 1 are exemplified. So can the roof, the balcony area or the terrace located under the balcony area each have such a covering device 1, but also the roofing of a carport or other application is conceivable.

On the basis of FIGS. 2 to 8 on the one hand and FIGS. 9 to 16 on the other hand, it is shown how the cover plates 2 reach their mutual position of use and how it is achieved that the edge-side contact regions 3 overlap such that impermeability to rain reaches these contact regions 3 becomes.

In both embodiments, it is provided that parallel to each other, at a respective cover plate 2 mutually spaced edges 5 and 6 are formed for a mutual rain-tight overlap according to Figures 6 to 8 and 14 to 16 different. At a first edge 5 is in each case a top 7 of the cover 2 weiteretzender web 8 and in use position under this ridge 8 belonging to the same first edge 5 gutter 9 is arranged, one edge tight and in the embodiments in one piece with the cover plate having them 2 is connected. The free edge 10 of the web 8 is set back relative to this rain gutter 9 and the other edge 11 of this rain gutter 9 is formed as a free edge, which in the position of use an edge-side web 12 which is still to be explained and which is near or close to the surface. Cover plate 2 engages below with distance. At the second edge 6 of the cover plate 2 is thus provided in continuation of its upper side 7 of the edge-side web 12 as the upper free edge. It can be seen in the above-mentioned drawings that this edge-side web 12 is partially opposite. is lowered over the top by the thickness of the located at the first edge 5 web 8 of the neighboring cover plate 2 such that in the position of use according to the already mentioned figures 6 to 8 and 14 to 16 of the web 8 of the first edge 5 of this second web 12 overlaps and the tops 7 are still aligned. If appropriate, an embodiment would also be conceivable in which the two webs 8 and 12 are arranged vice versa and then overlap. The drawings make it clear that the near-surface edge-side webs 8 and 12 of two in use position continuing cover plates 2 in the position of use at least partially surface or line contact, which already gives a certain seal against rain. However, rainwater passing through this contact point of the webs 8 and 12 is collected by the gutter 9 and can be discharged through it, so that the entire covering device 1 is rainproof. Complements and enhances this water tightness is in both embodiments, yet the fact that in the contact 3 of the two edges 5 and 6 of two cover plates 2, a second deeper-up or a rain gutter 13 provided for rainwater see ^¬ that there is provided at that edge 6 of the cover plate 2 is parallel to the edge 5 with the first gutter 9.

For a good mutual fixing in position of use is provided in both embodiments at the differently formed edges 5 and 6 of a cover plate 2 and thus at the contacting in use position edges 5 and 6 of two such cover plates 2 in the use position, a clamping connection. For this purpose, in the position of use, a Nand facing and touching edges 5 and 6 at a distance below the top 7 and thus below the webs 8 and 12 facing clamping webs 14 and 15 are provided, which overlap in the position of use according to Figures 6 to 8 and 14 to 16 and touch by clamping.

This clamping effect, which leads to a sliding fit at the contact points and thus facilitates the assembly to be explained, is achieved in the exemplary embodiments in that, prior to joining the at least two cover plates 2 which continue in the position of use, the clear distance between the above the first rain gutter 9 arranged, free-ending web 8 and the lower against the top 7 and this web 8 associated first clamping web 14 of the same edge 5 of the cover 2 is smaller than the outer distance between the overlapped in use position upper web 12 and the second clamping web 15 on the second edge. 6 is the neighboring cover plate 2 and that the first-mentioned, free-extending web 8 and located on the same edge 5 first clamping web 14 in use position to receive the counter-webs in their space and unfold due to the dimensions mentioned while the mentioned clamping effect.

It can be seen that the two clamping webs 14 and 15 each have a cross-section curved away from each other, so that their free edges can be pushed past each other easily during assembly, although this results in the already mentioned clamping effect in the further assembly process. In the figures 2 to 6 and 9 to 14 of the mutual assembly process for joining two in the position of use continuing cover plates 2 is schematized, but still clearly illustrated. Of importance here is that the distance between the free edge of the above the first gutter 9 extending web 8 is dimensioned by the free edge 11 of this gutter 9 both in Orientierungsrich- direction of the two cover plates 2 and in height such that in the area the top 7 of the other edge 6 of a neighboring cover plate 2 projecting web 12 according to Figures 2 and 3 and 9 and 10 at least obliquely inserted into this distance and space and then according to the following figures in the position of use can be pivoted. By this Einschwenkbewegung then reach the clamping bars 14 and 15 to each other and can slide over each other in the appropriate position of use and thereby unfold the clamping effect already described.

In this case, according to Figure 3 and also according to Figures 11 and 12, the second web 12 reach down to the bottom of the first gutter 9 and slide on the pivoting movement, so that it is also avoided that in the mating of the two edges 5 and 6 misalignments occur, which complicate or prevent the mutual pivoting.

Thus, the two are in the use position each other at least on the top of the cover 1 overlapping, free-ending webs 8 and 12 and the other underlying clamping bars 14 and 15 relative to each other in the orientation direction of the cover plates 2 first during the pivoting movement, according to Figures 7 and 8 and 15th and 16 also in the aligned position relative to each other in the orientation direction of the cover plates 2 slidably, wherein the displacement is limited by at least one stop. Especially the displaceability even in the mutual aligned position allows the collection of assembly inaccuracies and / or heat movement conditions and, where appropriate, occurring during loading minor deformations.

It should be mentioned that, for the aligned final position at least for ^: the position at which the two touching cover plates are pushed apart as far as possible, a stop web 16 is provided underneath the second web 12, which provides an even further displacement of the both cover plates 2 away from each other in cooperation with the rain gutter 9 prevents, in which he can wear up to the bottom in the use position.

The counter-stop for limiting the displacement of the two cover plates towards each other while is the boundary 18 of the second lower gutter 13. The lower second gutter 13th is divided by an upstanding in use position web 19 or divided according to their attachment side. The near-edge free part of this collecting channel 13 is provided for receiving water, which may additionally have penetrated in spite of the first rain gutter 9, which could exceed this separating web 19. Penetrates first between the two clamping webs 14 and 15 water in the second gutter 13, this is accumulated in the left in Figure 7 or 15 part of the lower edge region until it has risen so high that it can flow over the web 19, to then be absorbed and derived from the actual gutter 13.

It should be noted that the Querschnittslängert the webs. 8 and 12 and the second gutter 13 are dimensioned so that in the collapsed position of two touching cover plates 2 according to Figure 8 and 16 and the underside of the cover ^¬ device 1 is closed.

It can be clearly seen from FIGS. 2 to 16 that the cover plates 2 which continue in the position of use have a cross section perpendicular to these stiffening webs 20 in the position of use between their upper and lower boundary planes, the boundary planes being approximately plate-shaped and the stiffening webs 20 dimensioned in this way are that the cover plates 2 between their contacting in use position and mutually remote edges 5 and 6 and between its lateral to the edges 5 and 6 rather - stiffened angled edges and are load-bearing or even self ^¬ supporting. Thus, for example, the roofing of the Bal ^¬ cons 4 may be formed in Figure 1 only by the cover plates 2, which are supported only near the building wall and on two supports remote from the wall. Moreover, the entire roof can be virtually self-supporting. The balcony surface can be sufficiently stable with Hil ^¬ fe of the cover plates 2 designed in this way and corresponding cross sections of the webs and surfaces forming them to be charged and / or committed by persons.

It should be noted that located in the upper edge region of a per ^¬ weiligen cover plate 2 upper groove 9 to also located there, free and in particular rectilinear ending web 8 in continuation of the upper side 7 by an amount surmounted WEL ches in the embodiment approximately one-half the cross-sectional length of the upper free web 8 corresponds. The Re ^¬ genrinne 9 is preferably connected approximately in the middle of this upper web 8 in one piece with this. The stiffening webs 20 arranged between an upper and a lower level or layer of a respective cover plate 2 extend parallel to the edges 5 and 6 which contact each other in the position of use and overlap in regions, so that the cover plates 2 are made of aluminum or an aluminum alloy and / or Made of plastic - especially can be extruded. Overall, the cover plates 2 are formed at right angles and their four boundaries thus form a rectangle, which in the use position rain-tight overlapping edges 5 and 6 are the longer edges, so the longitudinal edges of such a rectangle. In this case, the length of the longitudinal edges may be a multiple or a multiple of the length of the transverse edges arranged at right angles in order to be able to provide a correspondingly elongated balcony with a roof covering, in which the individual cover panels 2 extend over the entire dimension of the roofing and in this Direction parallel to a house wall so can be uninterrupted.

The covering device 1 with cover plates 2 in the use position in a common plane and in at least one row is designed in a mutual edge contact area 3 by overlapping and thus rainproof, that edges 5 and 6 spaced parallel to each other on a respective cover plate 2 are formed differently and at a first edge 5, a top 7 of the cover 2 weiteretzender web 8 and under this web 8 a to the same first edge 5 or to the edge 6 of the neighboring cover plate 2 belonging gutter 9 are arranged. By overlapping in use position edge-side webs 8 and 12 optionally penetrating rainwater can therefore in the gutter 9 are caught under it.
