The U-legs end at the latter, the connecting web (4462) of the U-rib is constructed parallel to the foot-groove rib, and the height of the U-rib is less than the height of the foot-groove rib by the dimension a of an inner head-groove rib. <IMAGE>

Description

The present invention relates to a longitudinally displaceable grooved tile having a uniform top profile along its length, a side groove portion, a cover groove portion, a foot groove portion, and a head flank when the tile is installed.

A groove of the kind described above is described in DE-PS 26 44 227. This has worked well in practice. The overlap of the head when extended is particularly advantageous. However, as with longitudinal tiles, safety against rain is also a problem. The longitudinal sliding of the tile prevents costly but more secure head tiling, as is the case with classic, non-slidable slotted tiles.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a longitudinally slidable groove of the kind described in the introduction which, despite its high degree of longitudinal displacement, has improved rain protection.

According to the invention, the sole groove part comprises at least one U-rib which is closed on all sides and which is connected to a sole rib having a U-end terminating therein, and with its connecting rib being parallel to the sole rib and finally The height "h" of the U-rib is less than the height "H" of the at least one inner rib groove "a". The inner head groove rib is known and well proven. In order to maintain this, the U-rib was reduced by "a" relative to the sole groove. This provides the advantage of the U-rib being displaceable over the inner head groove.

The grooved tile of the present invention is simple in construction and provides improved sealing, particularly around the tile base and delicate quadriceps. The closed U-ribs on all sides are used to increase the flow resistance in the overlap area of the tile.

This is determined in known manner by slit width, slit length and surface roughness. Since ceramic products have a shape change and, with the coating, a change in the slit width and a fixed surface roughness, there is essentially only the possibility of changing the slit length.

The U-rib according to the invention provides an increased friction surface around the tile sole. This, together with the soles of the soleside arrangement, forms a closed field in which, as a result of the reduced pressure, any infiltrated water collects and is carried to the lower covered pot for dripping. From there, it can flow through the surface of the tile.

From a manufacturing point of view, the U-rib does not pose any problem, whether the grooved tile according to the invention is formed with or without a raised central part. This means that, with the correct design, it can be applied either in rows or in rows and joints. If the tile has a raised center section, it is advantageous to have a U-rib at each elevation. If there is no elevated midsole, it is possible to use a wide U-rib located below the midsole in the sole region. In order to further improve sealing, and in particular to reduce the gap width, in a preferred embodiment, the outer side panels of the U-leg are located on the inner side panels of the lid groove section and on the side panels of the raised center section.

In order to increase the flow resistance behind the U-rib, it is advantageous to have a flat surface connected to the U-rib whose length is at least as long as the respective tile offset length, and which when the tile is moved over the headband slides forward with a minimal residual "s" gap. This remaining "s" gap is maintained throughout the shift.

It may be advantageous to have both planar planar surfaces in the same plane.

In order to further increase the flow resistance, in a further preferred embodiment, transverse ribs are arranged between the two U-ribs, which are laterally bounded by the outer side panels of the U-ribs, with these side panels extending downwards to form a trough. they are uniform and, when covered, lie on the median plane surface of the lower deck tile. As a result, the infiltrated water falls downward and is led outward through the lower lid.

For tiled tiles in the longitudinal direction, the four-tile corner provides minimum cover length. In order to utilize this minimum cover length in critical areas of the sidewall, middle, and sidewall portions, in another preferred embodiment, additional ribs are provided for joining to the ribs, the height of which is selected so as to displace the tile. they slide over the headband. These additional ribs also serve to create a reduced pressure on the underside of the tile, increasing the flow resistance to allow the infiltrated water to drip and fall.

In addition to utilizing the maximum cover length in the four-tile corner, there is a need to improve headroom tightness around critical areas of siding, center and siding. To this end, extensions are provided on an inner side groove rib, and optionally around a raised central portion, extending from the headband to the tile center and having the same height as the headband.

For the same reason, it is advantageous if the headboard groove encircles a flat surface that has the same height as the headband and has the same length as the extensions.

In order to further improve the sealing effect in the four-tile corner, it may also be advantageous that, if there are recesses in the head corner recess, an external L-shaped rib is provided for the outer boundary of the trough, preceded by a recessed flat surface.

Figure 7 is a plan view of two adjacent grooved tiles joined together;

Figure 8 is a partial top view of a second embodiment of a grooved tile according to the invention, without a raised middle portion;

Figure 9 is a partial bottom view of the embodiment of Figure 8.

Turning to the detailed description of the figures, FIGS. Fig. 4a shows a first embodiment of a grooved tile according to the invention. It has a head groove part 2, a lid groove part 3, a base groove part 4, a side groove part 5 and a raised middle part 6. This tile can be stacked in series as well as - due to the raised middle part - 6.

Figure 1 illustrates the top side of a tile according to the first embodiment. The head groove portion 2 surrounds the head edge strip 211 which forms the head end of the tile and extends from the head groove 28 to the head groove corner groove 29 at the same height and width. There, the headboard is connected to a plane surface 2113 having a height corresponding to the height of the headboard 211. The flat surface 2113 is located around the corner cutout 295 in the headboard groove 29 and terminates on the outer tile side of the cover groove portion 3.

The extension of the planar surface 2113 in the offset direction, i.e. the longitudinal direction of the tile, corresponds to the extension of the extensions 2112 extending from the headband 211 to the middle of the tile. In the present case, three such extensions 2112 are shown, one on the inner side groove 517 and one on the sides 613 and 615 of the raised middle portion 6. The extensions 2112 are as high as the headband 211.

In front of the headband 211, two inner head grooves 217 are provided, which are located in the left and right center grooves 614 and 616, respectively. These are provided with an overflow 2171 to allow dewatering of the space between the inner head groove rib 217 and the headband 211.

Figure 5 shows that the inner head groove 217 has a height "a". One to be described later

The height "h" of the U-rib 446 is selected such that it slides over the inner head groove rib 217 as it is longitudinally displaced.

As illustrated in Figure 1, the headband 28 in the head corner 28 further extends recessed from an L-rib 285, which not only forms the corner boundary of the grooved tile, but also establishes a connection between the side face and head. This L-rib 285 encloses a recessed planar surface 286 which, however, is substantially below the L-rib 285 above the recess 5141, which forms the common end of an outer sidewall groove 514 and a central sidewall groove 516.

Page blur is structured as follows:

The outer boundary of the grooved tile is formed by an outer side groove rib 513, followed by an outer side groove 514 already discussed towards the center of the tile. On this

Between the 514 side wall recess and the middle 516 side wall recess, also discussed,

515 side groove ribs. Towards the center of the tile, the closure is formed by the inner side groove ribs 517, which was also discussed. The lateral ribs and flutes extend from the head groove part 2 to the sole groove part 4, with the same profile. The sidewall grooves 48 open in the vicinity of the bottom groove corner 48, in a side-sloping collection groove associated with a triangular drain 489. For this purpose, the outer and central side groove ribs end up sloping.

The drain 489 is located in front of a base groove cutout, which is delimited from the center of the tile by the inner rib groove 517. This extends to the base end of the tile.

The cover groove part 3 surrounds a top groove center portion 312 on the upper side of the tile, extending from the head groove part 2 to the foot groove part 4 with the same profile. An inner cover groove side 313 establishes a connection with the adjacent right middle groove 616.

Previously, the top of the tile has been described, and now the bottom side of the tile, shown in the bottom view of Figure 2, will be described.

The base groove part 4 has a base rib 44 forming the base end of the tile, which is divided into a cover part 441, a middle part 443 and a side part 445. The latter forms an L-rib defining a corner cut-out in the groove 48 in the base. The larger L-mandrel extends over the entire width of the side groove portion S, the smaller L-mandrel points in the offset direction and engages with an elevated right pin 444 located below the left mid-trough 614. In accordance with this arrangement, there is a left-hand pin 442 which is similarly located below the right-hand central trough 616. The pins 444 and 442 thus form the connection between the aforementioned sections of the sole 44.

Figure 5 shows that the pins 444 and 442 are of "H" height and serve to seal the overlapping grooved tiles at the lower end of the lid.

HU 209 408 Β

The left and right pins are assigned a 446 U-rib closed at each side. The beams 4461 of this end terminate on the soles 44, where the connecting rib 4462 of the U-rib 446 is parallel to the soles 44. The height "h" of the U-rib 446 is at least smaller than the height "H" of the sole 44 by at least the size of the head groove 217. This is illustrated in Figure 5. The U-ribs 446, together with the sections 442 and 444 of the sole rib 44, together with the pins, form a recess 447 which is closed from all sides.

As shown in Fig. 2, there are intermediate sections 443 and transverse ribs 4431, 4432 and 4433 separated by intermediate spaces around the backside of the raised center portion 6. As shown in Fig. 4, the center portion 443 and the transverse rib 4431 are of the same height and, at the time of covering, form a support for the tile to be covered.

The other transverse ribs 4432 and 4433 are also of equal height, but their height is defined so that they can slip over the headband 211 when covered. This means that their height is at least less than that of the mid-section 443 and the transverse rib 4431 by at least the height of the headband 211.

The transverse ribs 4432 and 4433 are in a plane with lateral planar surfaces 448 extending from the base side below the mid-troughs 614 and 616.

The length of the planar surfaces in the longitudinal direction of the tile is at least as large as the required offset length of the tile. Figure 5 shows that there is a residual gap "s" between the planar surfaces 448 on the one hand and the headband 211 on the other. This shall be maintained over the entire offset length and shall be as small as possible.

The already negotiated intermediate spaces between the ribs 443, 4431 and 4433 are formed by the recesses 4434. It is important for the operation of the invention that the transverse ribs 443 and 4431 are arranged between the U-ribs 446. These transverse ribs are laterally delimited by the outer 4461 stems and sides of the Ub ribs. These stems 4461 in this region contribute to the creation of the recess 4434 while they are bent downward. It is also important that the center portion 443 and the cross rib 4431 have the same height and, when covered, seal the middle surface 611 of the tile to be covered.

Below the center troughs A614 and 616 are provided support ribs 622 extending from the head portion to the same surface 448 with the same profile.

The underside of the cover groove portion 3 comprises an outer cover groove rib 323, an outer cover wall latch 324, a central cover groove rib 325, and a central cover latch 326. They also lead with substantially the same profile from the headboard corner groove 29 to the base cap groove 49. Analogous to the upper end, they terminate obliquely and leave a free space between their ends and section 441 of the foot groove. From the front side, they were connected by the 3232 ribs. The height of this rib 3232 exceeds the height of the two cover grooves 323 and 325. When sealed, the rib 3232 fits into the 5141 trough designed for this purpose.

In the area around the corner cutout 295 of the headboard corner groove 29, a recess 296 is provided which overlaps the L-rib 285 in the planar surface of the headstock 28 of the tile top. This recess 296 is required so that the L-rib 285 can be applied to the top of the tile without affecting the pile's build-up.

Figure 3 schematically illustrates the overlap of two tiled I and II tiles.

The U-ribs 446 are identified by a dashed line with the troughs 447. The outer U-ribs 446 of the left-hand U-rib 446 lie on the inner side 5171 of the inner side-groove rib 517, while its outer side lies on the side 613 of the central portion.

Similarly, the left side 5171 of the left U-groove 446 is located on the inner surface of the extension 2112 on the inner side groove 517. The right side of the U-rib 446 is located on the left-hand side of the central portion 2112 extension. The right side surface of the right-hand U-rib 446 is on the inner side surface of the flat surface 2113 of the cover groove portion 3.

The lateral surfaces of each of the U-ribs 446 follow, on the one hand, the profile of the tile to be covered and, on the other hand, the corresponding side surfaces of the extensions 2112 and the planar surface 2113. This close alignment of the U-ribs 446 with their respective members increases the flow resistance in the gaps in the head groove range and the tile overlay, thereby increasing the safety against rain.

The cross-section of the tile to be overlapped is designed to avoid excess material accumulation in the region of the lateral sides 613 and 615 of the center portion 6. The function is the same as described above.

Figure 4 is a longitudinal sectional view of two overlapping tiles I and II in the vicinity of the raised central portion 6.

The center portion 443 of the outer sole 44 and the cross rib 4431 seal against the center surface 611 while minimizing the residual gap. Between the two ribs 4431 and 443 there is a first recess 4434.

The transverse rib 4431, when extended, encounters one of the extensions 2112. The outer side 5171 of the U-ribs 446 is shown. The heights of the transverse ribs 4432 and 4433 are chosen such that the heights of the transverse ribs II. as the tile is displaced longitudinally, it slides over the headband 211 of tile I and there is only a minimal gap between them.

An additional 4434 recesses are provided between the ribs 4433 and 4432.

Connected to the last transom 4431 is the underside of the middle portion 6.

The 4434 recesses form a vacuum chamber or a vacuum chamber, thereby increasing flow resistance and rain

EN 209 408 B safety. The transverse ribs 4433 and 4432 are spaced so as to directly overlap the headband 211 at the most commonly used cover lengths.

Figure 5 is a longitudinal sectional view of two overlapping pots I and II in the mid-trough region 614. The AII tile is not fully drawn to make the representation clearer.

The right peg 444 of tile AII rests on the middle trough 614 of tile I on the left. Connected to pin 444 is a U-rib 446 having a trough 447. The height "h" of the U-rib 446 is selected to slide over the inner head groove 217. In the retracted position, the inner side of the pin 444 abuts the outer side of the head groove rib 217 and the side 4462 of the U-groove 446 abuts the inner side of the head flange 211.

One of the extensions 2112 is located in front of the headband 211.

The trough 447 creates a low-pressure chamber that increases flow resistance and drips wind-blown water particles.

Figure 6 is a sectional view showing the rectangular overlap of tiles I-IV.

The tile I is shown in side view, the tile II is intersected around the corner cutout 295 of the headboard groove 29, the tile III is shown in the side view around the groove corner 48 and finally the tile IV is intersected around the base groove 49.

The U-shaped connecting rib 3232 of tile grooves 323 and 325 extending from tile AII is located within trough 5141 of tile head 28.

Tile I shows the lowered surface 286 of the installed L-rib 285 and the headband 211.

The tile AIII shows the drain 489, which extends over the side grooves 513 and 515 which are also overlapped here. Of the AIV tile, only the cover groove part 3 is in section.

Figure 7 is a top view of two tiles I and II stacked side by side. The U-shaped rib 3232 of the Ali tile connects the two top groove ribs 323 and 325 and is seated in the recessed 5141 trough of tile I. Between Tile I and Tile II is the vertical Page Selector Joint 962.

Fig. 8 is a plan view of a second embodiment of a roofing tile according to the invention, without a raised middle portion. The figure shows the head 2 of the cover.

The second embodiment substantially corresponds to the embodiment of Figs. . For the sake of simplicity, the same components will be provided with the same reference numerals. In the following, only the differences and some noteworthy details are discussed. Otherwise, reference is made to Figures 1-7. Figures.

The second embodiment does not have a raised middle section. The consequence is that the middle portion is flush from the side groove portion 5 to the lid groove portion 3. The inner head groove rib 217 thus extends continuously from the inner side groove rib 517 to the inner side groove side 313 of the lid groove part 3. It has two 2171 overflows.

As a further consequence of the changed center portion, the extensions 2112 are omitted. Such an extension can be found only on the inner side groove 517.

Figure 9 shows the underside of the roof tile shown in Figure 8. Here, too, there are consequences because the middle of the tile is flat. It extends through the base rib 44 from the corner of the base groove 48 to its lowered portion 441, located below the base groove 49 of the base.

The L-rib 445 is connected to the region of the bottom groove corner 48. Connecting to the soleplate 44 is again the U-rib 446 that now passes through two troughs 447. Between the two troughs 447 is located one or more longitudinal ribs 4463 having the same height as the U-rib 446. The connection to the 446 U-rib has 4434 troughs. This trough 4434 is also surrounded by a planar surface 448 which is directly above the headband 211 of the tile to be covered. One or more 4434 troughs or recesses are only required when required for manufacturing purposes. For safety against rain and to reduce the gap between headband 211 and planar surface 448, it is preferred that the planar surface 448 passes uninterruptedly, i.e. recess 4434, to the U-rib.

In the first and second embodiments, when covered, when extended, the leg 4451 of the L-rib 445 lies in the corner cut-out to the extension 2112, in the vicinity of the inner side groove 517 of the tile to be covered.
