Description

The present invention relates to a miter tile for roofs which

  comprises a simple system of lateral assembly by tabs comprising an external rib and an internal rib arranged on the side, a central zone of the tile, at least one covering bead and a simple system of assembly by tabs

  comprising an outer rib and an inner rib

  higher passing over the middle area of the tile

and the covering bead.

  A known roof miter tile of this type does not allow a significant longitudinal displacement or an optimal seal in the areas of the assembly systems located at the level of the head and on the side.

tile.

  The object of the invention is the production of a miter tile for roofs of the type initially defined which, with a minimum of overlapping in the longitudinal direction, offers a possibility of displacement as large as possible in the direction of the length while

  ensuring an optimal seal even at the point of rush

tion of four tiles.

  This object is achieved, according to the invention of the fact that the tile comprises, in the area of its foot, an external rib which is applied to the middle area of the tile and essentially on the bead covering the covered tile and that the outer rib of the tile head area extends with a weak

  clearance to the bottom surface of the tile which overlaps

  vre the other, because the heights of the inner rib of the area of the head of the tile and that of an inner rib of the area of the foot of the tile are approximately equal and are only less than a small clearance at half the height of the outer rib of the area of the foot of the tile and that the assembly system located in the area of the head of the tile, in the area of junction of four tiles has an area in tray surrounded by ribs which is only open towards the groove of the assembly system of the area of the head of the tile and, therefore, towards the middle area of the tile. The possibilities of longitudinal displacement of a miter tile for roofing of this type are not limited by the inner rib of the area of the head of the tile nor by the inner rib of the area of the foot of the tile, because these two lower ribs can be crossed by sliding. At the same time, it is ensured that the inner groove of the area of the

  head of the tile is, in each position of move-

  ment, always below the plane which passes through the upper edges of the outer and inner ribs of the head part of the tile and, therefore, achieves a

  authentic labyrinth seal. This results in an excel-

  slow waterproofing against gusts of rain and snowstorms at the same time as an overlay

  minimum in the head area of the tile.

  The roof miter tile F according to the

  vention provides a quadruple overlap in the junction area of four tiles. The structure of the tray area according to the invention which intervenes at the junction point of four tiles offers the guarantee that, whatever the position of movement, no gap occurs at the junction point of four tiles, which ensures a optimal sealing. Water is removed from the plateau area in question by

the middle area of the tile.

  It is advantageous that the covering bead is in the lateral overlap zone and that the tile has a median bead in the middle of the zone

median of the tile.

  In an advantageous embodiment of the miter roof tile according to the invention, a middle rib of the head of the tile located between the outer rib and the inner rib of the head has the same height as the inner rib of the head and a midrib of the foot located between the outer rib and the inner rib of the foot has the same

  height than the inner rib of the foot. This provision

  sition further improves sealing in the area of the

head of the tile.

  It is advantageous that the inner rib of the head has at least one passage for the evacuation of water to the middle area of the tile, that the middle rib of the tile and that the middle rib of the head have at least a passage for the evacuation of water to the middle zone which is offset laterally with respect to the passage formed in the inner rib of

  the head. This arrangement achieves, in the area of as-

  semblance of the head, an additional labyrinth seal

keep quiet in the lateral direction.

  It is advantageous that the groove between the outer rib and the middle rib of the head

  is separated from the flat area by a longitudi-

  nale. Therefore, the evacuation of water from this flat area to the middle area of the tile takes place

along the shortest path.

  In one embodiment of the miter roof tile according to the invention, the side of the covering bead has a shape such that it forms, with the surface of the upper side of the inner rib of the lateral zone of the tile located at - above a horizontal separation joint. This results in the possibility of minimal overlapping along with sealing

  optimal in the lateral area. The penetration of dirty-

  tees, foaming and overflowing of water out of the lateral groove are made impossible by the fact that the separating joint is raised relative to

to the middle area of the tile.

  It is advantageous that the inner rib of the lateral system is. extends while maintaining its full height up to the foot of the roof tile and comprises, at the foot of the roof tile, a rib extension, with the bead covering, a part of the separation joint inclined towards the outside. It is advantageous that the outer rib of the lateral assembly system is rectilinear over its entire height to a point distant from the foot of the tile.

  slightly larger than the long displacement

  maximum tudinal and stops at this point.

  At the time of stacking, an outer rib of the stacking system engages in the lateral groove formed by the ribs of the lateral assembly system while an inner groove of the stacking system is placed laterally above

  of the outer rib of the lateral assembly system.

  The water is drained from the groove of the lateral system directly from the flat insertion area.

  It is also advantageous if the tile

  door, following the head area, in the middle area of the tile near the inner groove of the lateral assembly system and the covering bead,

  a closure spout with a longitu-

  dinal corresponding to the maximum displacement path in the longitudinal direction and of the recesses made in the outer rib of the foot of the tile. These recesses made in the outer rib of the foot allow, for the manufacture of miter tiles for roofs, to use small unitary frames, while the closing spouts cover these recesses, after covering, so as to ensure sealing and to

give a pleasant appearance.

  In another embodiment of the miter tile for roofs according to the invention, the area of the foot of the tile comprises, on the lower side of the tile, two longitudinal pieces whose height reaches the median area of the covered tile and which are placed in the passages provided for the evacuation of water in the inner rib of the head. These longitudinal pieces provide additional sealing in the area of the water evacuation passages at the level

of the head.

  The head area can also include, in addition, on the lower side of the tile, at least in front of the outer groove of the head, two suspension spouts, the height of which goes to the bottom of the groove of the head. the overlapping tile which is in the same plane as the

  area of the middle area of the tile.

  This arrangement allows the stacking of miter tiles for roofs according to the invention, under conditions such as the height of the superimposed tiles.

  per stack is equal to the height of the superpo-

  for their installation on the roof. The support for stacking is done exclusively on the median zone or on the bottom of the groove which is in the same plane as this median zone. The possibility of moving the tile in the longitudinal direction is not limited by the longitudinal pieces (parts) which are used for stacking

  nor by the hooking spouts. In addition, the spouts

  hooks engage, for stacking, in the groove of the head so that the stacked stack of tiles are perfectly locked without risk of slipping and that one can place a stack of tiles on a roof without

  that one or more tiles can slide.

  The invention is described below in more detail by means of exemplary embodiments.

  shown in Figure 1 halfway up the tile.

  Figure 6 is a schematic view, at the foot of the tiles, miter tiles for roofs

  like the one shown in Figure 1.

  The miter roof tile shown in Figures 1 and 2 includes a middle zone 1, a simple lateral assembly system 2 and a system

  simple assembly 3 at the head area.

  By simple assembly system is meant an assembly system in which at least one rib formed on the lower side of the tile engages in a groove delimited by two ribs formed on the upper side of the tile, so that it enters the plane passing through the upper edge of the ribs on the upper side of the tile

  and thus creates an authentic labyrinth seal.

  The mitered roof tile represented by FIGS. 1 and 2 also comprises a median bead 4 situated in the middle of the median zone 1 of the tile and a covering bead 5 comprising a side bead 6 of covering bead. The head of the tile has an outer rib 7, an inner rib 8 and a middle rib 9. The inner rib 8 of the head passes over the middle zone 1 of the middle bead 4 and the covering bead 5. The system of assembly 3 of the head comprises, in the junction area of four tiles, a tray area 10 which is surrounded by ribs so that it is only open in the direction of the groove in the head area and, therefore, from the middle zone 'l of the tile. The groove between the outer rib 7 of the head area and the middle rib 9 of the head area is separated from the

  zone 10 forming a plate by a longitudinal rib 12.

  The inner groove 8 of the head area has two open passages 13 for the evacuation of water to the middle area 1 of the tile and the middle rib 9 of the head area has two openings 14 to the middle area 1. The passages 13 and 14 for the evacuation of the water are offset laterally with respect to each other, which constitutes, in the groove of the head area, a labyrinth seal in the lateral direction .

  An outer rib 15 and an inner rib

  16 of the lateral zone form a lateral groove

  rale 18. The inner rib 16 of the lateral zone is rectilinear over its entire height up to the foot of the tile and, at the foot of the tile, has a lateral extension 17. This lateral extension 17 has a shape such that with the covering bead 5 in the roof covering it forms a part of the separation joint

  inclined obliquely outwards. The outer rib

  upper 15 of the lateral zone extends in a straight line over its entire height to a point distant from the foot of

  the tile of a measure slightly greater than the displacement

  maximum longitudinal length and stops at this point.

  Following the head area, the middle area 1 comprises, near the inner rib 16 of the lateral area and the covering bead 5, closing nozzles 19 whose lateral extension corresponds

  at maximum longitudinal displacement.

  As shown in Figure 2, the underside of the roof miter tile has an outer rib 21 in the foot area, an inner rib 22 in the foot area and a middle rib 23 in the foot area. In addition, the outer rib 21 of the foot area has two recesses 20 in which the closure spouts 19 come to bear at the time of covering and which complete the sealed closure of

the groove of the head.

  The lower side of the tile also has an outer cover rib 24 and a rib

inner 25 of cover.

  The outer rib 21 of the foot area has a shape such that at the time of covering it bears on the middle zone 1 and essentially on the median bead 4 and on the bead covering 5 of the covered tile, while the outer rib 7 of

  head approaches with a slight play of the lower surface

  the tile that covers the other. The heights of the inner rib 8 on the side of the head and of the inner rib 22 on the side of the foot are approximately the same and less, with a slight clearance, to half the height of the outer rib 21 on the side of the foot. The middle rib 9 on the side of the head has a height equal to that of the inner rib 8 on the side of the head and the middle rib 23 on the side of the foot has a height equal to that of the inner rib 22 on the side of the foot. This does not preclude the

  longitudinal displacement of the roof miter tiles

  res that overlap each other.

  The flank 6 of the covering bead has a shape such that with the surface of the upper side of the inner rib 16 of the covered tile it forms a horizontal separation joint. This is clearly shown

Figure 5.

  In the foot area, on the bottom side of the

  tile, it also has two longitu-

  dinales 26 whose height reaches the median zone 1 of the covered tile and which can be supported in the passages 13 provided for the evacuation of the water in the inner rib 8 of the head zone. This results in an additional labyrinth seal in the area of the

rib 8 of the head area.

  Finally, the head zone comprises, on the lower side of the tile, opposite the external groove of the head zone, two hooking nozzles 27, the

  height reaches the bottom of the super tile groove

  laid which is in the same plane as the middle zone 1 of the tile. The longitudinal parts 26 and the hooking spouts 27 are sufficient to produce a stack in which the tiles have the same height, one by

  compared to others than in their cover provision

  ture. In addition, because the hooking spouts 27 engage in the outer groove of the head area, the stacked stack of tiles is perfectly

  locked and without risk of slipping.

  Figure 3 shows schematically the mode

  for assembling miter tiles for roofs shown

  felt by Figures 1 and 2. The figure shows clear-

  ment that the inner rib 8 of the head area and the middle rib 9 of the head area, as well as the inner rib 22 of the foot area and the middle rib 23 of the foot area do not interfere conversely for a longitudinal displacement of the

miter roof tile.

  FIG. 4 represents a suction device

  similar appearance at head level, without midrib 9 of the head area and without midrib

23 at the foot.

  5 shows the method of assembly at the sides of miter tiles for roofs like that shown in Figures 1 and 2. It clearly highlights the horizontal separation joint between the side 6 of the covering joint and the surface of the side

  upper of the inner rib 16 of the lateral zone

  rale. FIG. 5 also shows that the outer rib 24 engages in the lateral groove 18 formed by the outer rib 15 of the lateral zone and the inner rib 16 of the lateral zone, while the inner rib 25 engages laterally top of

  the outer rib 15 of the lateral zone.

  Figure 6 shows schematically the em-

  pounding of miter tiles for roofs like the one shown in Figure 1. It clearly shows that the height of the tiles stacked one above the other is equal to the height of the tiles stacked for

  blanket. In addition, Figure 6 clearly highlights

  dence the rib extension 17 and the part of the separation joint inclined obliquely towards the outside which is formed by this extension and by the covering bead 5.
