[0001] It is to be considered that in the downstream part of the roofs with tile covering
eaves tiles are used, so known because they are the tiles placed near the eaves. Currently,
the eaves tiles are realized placed the tiles with concavities upwards with a distance
enough to can place, in complementary way, tiles with concavity downward. This mounting
system determines covering that guarantees impermeability and contemporary permits
the aeration of the underlying part of the roof. For the position keeping, the tiles
with concavity upwards are fixed to the roof with cement mortar and common joists
are placed to rise the first line of tiles so to not -have angles between the tiles
and have planarity characteristics to the tile covering or small relieves in this
first line. Unfortunately, the cement mortar, applied to the tiles in these points,
permits the imbibition. Infact, the driving rain or condensation forms are absorbed
to the cement mortar favouring infiltration under the covering. Moreover, such as
the current eaves tiles must permit the aeration to the underlying part of the roof
they are subjected to water infiltrations, coming to the part near the gutter, in
the case of driving rain or of winds affecting onto the water layer caused to the
rain flowing from the roof to the underlying gutter. The invention refers to a new
eaves tile able to permit a high impermeability to the roof and contemporary to determine
a good aeration of the part of the roof underlying the tiles. Moreover, the invented
eaves tile is able to eliminate the use of the common joist and the cement mortar
actually used. Moreover, the invented tile determines a higher mounting speed in comparison
with the realizations known in the prior art. The invented eaves tile consists of
a body 1 in polyurethane resin or in vibrating-compressed cementer mixture , impermeabilized
with resins and treated onto the surface with water-repellent products. Said body
1 has a back vertical wall 2 with upper outline border 3 having the inside profile
of the tiles. Onto said back wall 2 are then present holes 4 with diameters of bigger
dimensions toward the outside part of the wall 2, considering for the outside part
the part placed in front of the eaves. Perpendicularly to the back wall 2 and on the
outside part two concave surfaces 5 and 6 are present in material continuity with
the back wall 2. Said concave surfaces 5 and 6 have protruding parts 7 and 8 placed
in the middle of the corresponding cavities and having blind holes 9, 10, 11 and 12
suitable to contain the teeth 13, 14, 15 and 16 placed onto the lower wall 17 of the
tile-shaped body 18. Onto the lower part of the tile 1 is, moreover, present a drop-break
groove 19. In composition of the two bodies 1 and18, the protruding part 7 with the
blind holes 9 and 10 contains the teeth 13 and 14 whereas the protruding part 8 with
the blind holes 11 and 12 contains the teeth 15 and 16. Other teeth 20 and 21, placed
under the body 18, come to put in the concavities 5 and 6, over the protruding parts
7 and 8 so bigger limited the translation possibility long the roof plane. In material
continuity then are present, under the concave -surfaces 5 and 6, the protruding parts
22 and 23 that form the points of support the eaves tile 1-18 to the roof plane. The
back wall 2 has, moreover, an arc vertical profile 24 with border 25 so to be brought
near the corresponding vertical border 26 of an adjacent eaves tile 1-18 so closing
the possible spaces between the adjacent bodies 1 and recovering in this way the inevitably
tolerances to the mounting between the bodies 1. In positioning phase, the invented
eaves tile 1-18 provides the blocking to the roof of the body 1 by means of suitable
glues placed onto parts 22 and 23 which form the points of support to the roof. Long
the same line, and in adjacent manner to the first tile 1, a second tile 1 is laterally
placed with the arc profile 24 of the first tile in contact with the border 26 of
the following one. In prosecution are so fixed a number of tiles 1 as requested to
the length of the roof border. In each body 1 are then placed a corresponding number
of tile-shaped bodies 18, being careful to put the teeth 13, 14, 15 and 16 into the
corresponding blind holes 9, 10, 11 and 12 and the teeth 20 and 21 into the concave
surfaces 5 and 6. In the same manner it is possible gluing directly for all the length
of the roof border the eaves tiles 1-18 already assembled, i.e. with the bodies 1
and the tile-shaped 18 already connected with the teeth inserted in the corresponding
blind holes and into the cavities. Then it is to be considered that the back wall
2 has holes 4 so it is able to permit the air passing connected to the convective
motion and to avoid water infiltrations under the roof. Infact, it comes to form a
sole wall without openings under the tiles such as the arc profile 24 in contact with
the border 26 of the body 1 placed following permits the rain seal infiltrated for
the wind in said positions. Moreover, the flaring of the holes 4, oriented in the
way previously described, favours the ventilation of the garret thanks to the Venturi
effect that is created in said area. Instead, in presence of perturbations with wind,
the heat present in the garret inverts the air flow passing to the holes 4. The air
circulation is so able to go out to the holes 4 avoiding to the drops or to the water
sprinkles to penetrate over the back wall 2 and the conicalness of the holes 4 is
so to make falling down eventual drops or water sprinkles toward the eaves. The invented
eaves tile is of immediate and speed mounting for the covering of roof and it has
not the necessity of joists or of fixing with cement mortars to have the planarity
of the tiles in the covering of for the small rising of the tiles placed near the
eaves. Moreover the invented tile avoid the enter of the birds or of other animals
under the tile covering. The invented eaves tile is illustrated in a merely indicative
way in the drawings of sheets 1, 2, 3 and 4. In sheet 1 figure 1 is frontal view of
the support body 1. In sheet 2 figure 2 is top view of the body 1. Figure 3 is under
