Description

The invention relates to a ventilation tape according to the restrictive part of paragraph 1 of the claims.

Ventilation tapes are often used to seal the gap between the ridge or rib beams on a roof with steep slopes. They are made, as a rule, in the form of rolls that are unwound on the ridge or rib beam.

Such ventilation tapes serve, on the one hand, to prevent the ingress of water, snow or harmful insects into the interior of the roof, and on the other hand, however, to ventilate the space under the roof so that, for example, no formation occurs condensation water or the formation of rot or, respectively, mold. Known ventilation tapes do not meet all these requirements. If they retain water, snow, and harmful insects, then they are often not permeable enough to air.

Known ventilation tape, which has one middle strip and two side strips, and the side parts contain holes (US 5094041). In this case, the side parts may consist of pieces arranged like an accordion on top of each other.

Further known ventilation tape with one middle strip and two side strips, the middle strip of which contains holes (GB 2155516 A). On the side strips there are substantially vertically standing fresh air ventilation strips in which openings are provided.

Further, a ridge or rib strip with a forced ventilation function is known, which consists of a strip corrugated at the edges and passing air in the center (EP 1260650 A2). This strip has provided in its center, extending across the strip of the recess, closed by bringing to each other passing in the transverse direction of the ribs.

In addition, a ventilation element for the attic is known, which has several supply ventilation walls that are located between the upper and lower plates (JP 2001323618 A). These supply ventilation walls are vertical or oblique and have several openings. However, this ventilation element cannot be rolled up.

The basis of the invention is the task of creating a ventilation tape that guarantees a good air exchange, without water, snow or harmful insects falling through this ventilation tape.

This problem is solved according to the characteristics of paragraph 1 of the claims.

The invention thus relates to a ventilation tape with at least two side strips running parallel to each other and one middle strip. Parallel to the side strip are ventilation strips, which are formed by walls or partitions connected along the perimeter to each other. At the same time, ventilation strips can have a variety of forms. At least one ventilation duct is provided, however, several ventilation ducts may be provided. Due to the use of certain materials for the ventilation tape, which have a restoring force, at least one ventilation duct can independently open when the ventilation tape is unwound. However, it is possible by stretching over the side strips to cause the opening of at least one ventilation duct.

The advantage achieved by the invention consists, in particular, in that the ventilation tape unwound from the roll has ventilation openings with good ventilation characteristics of a surface lying below the roof level, and these ventilation openings are protected against gusts of rain, snowstorm and the like. Penetration of gusts of rain or flying snow is prevented by one or more channels, which consist of breathable or dense materials with holes. In this case, the ventilation area can either be geometrically constantly open, or form a channel or channels only later, i.e. after unwinding the ventilation tape. According to the invention, various ventilation planes can be formed which are either adjacent to each other on the sides or in the integrated position, one above the other with offset. In addition, each additional ventilation plane represents the next barrier against the penetration of gusts of rain. The drainage channels in all planes except the innermost ones allow water to flow out in the possibly present intermediate planes.

Examples of the invention are presented in the drawings and are described in further detail below.

Figure 1 shows the ridge 1 of the roof with roof tiles 2, 3, 4, 5, 6, 7, 8, 9 and with the ventilation tape 10 according to the invention, which has two side strips 11, 12 and one middle band 13. Side strips 11, 12 lie on the roof tiles 2-9, while the middle strip 13 lies on the ridge beam 14. The side strips 11, 12 consist of plastically deformable material, or contain it at least at their end, so that they adapt to the shape of roof tiles 2-9. This is not shown in FIG. 1.

In the following, only the right region of the ventilation tape 10 is described, since the left region is constructed in the same way as the right region and is mirror symmetrical to it.

Between the side strips 11, 12 and the middle strip 13, a ventilation channel 15 is provided, which has a rectangular shape, which is formed by four walls 16, 17, 18, 19. In the walls 17 and 18 there are holes (grooves), which are not visible in figure 1 . While the wall 19 is formed by the middle strip 13, the wall 16 is formed by the side stripes. The wall 18 may also be part of the side strip 12. Accordingly, the same applies to the wall 17, which may be a continuation of the middle strip 13.

Figure 2 presents a side view of the ventilation tape 10 according to figure 1. In this case, the side strip 12 is visible, as well as the middle strip 13. Several holes (grooves) 20-25 are provided in the wall 17. The holes in the opposite wall 18 are not visible in figure 2.

The ventilation channel 15, which is formed by the walls 16-19, is enlarged shown in Fig.3. In this case, we are talking about the area indicated in figure 1 as "A". You can see the holes 20, 21 provided in the wall 17, as well as the holes 26, 27 provided in the wall 18. The holes 26 and 27 are offset with respect to the holes 20, 21 by a distance “b”. If, for example, flying snow was supposed to pass through holes 20, 21, then it runs on the opposite wall 18 to a closed surface, and not to hole 26, 27. Due to the location of holes 20, 21, 26, 27, a kind of similarity arises the maze. The incoming air turns on its way to the inside of the roof, as a result of which flying snow does not have access to the inside of the roof. In order to allow water that flows through the openings 20, 21 to the ventilation duct 15 to flow out again, it is recommended to allow the openings 20, 21 in the wall 17 to pass up to the wall 16. This is indicated by shading 28, 29. However, it is also possible between the openings 20 21 and wall 16, provide separate openings in the wall 17, which serve as water-discharging openings.

On figa shows another embodiment of the ventilation tape 45 in horizontal projection. In this case, two side strips 30, 31 and one middle stripe 32 are again visible. With regard to the regions 33, 34 of the middle stripe 32, we are talking about those that are connected to the wave-like side strips 30, 31, for example, glued. In the middle strip 32, namely, near the regions 33, 34, holes 50 and 51, respectively, which are formed as round holes, are provided. Behind these openings 50 and 51, a strip material is visible, since the ventilation tape 45 is compressed. In a compressed state, it can roll into a roll.

Fig. 4b shows the same ventilation tape 45 as in Fig. 4a, however, in a bottom view, i.e. upside down. In this perspective view, the ventilation tape 45 is in an uncompressed state. This ventilation tape 45 has two ventilation ducts 185, 186 running parallel to each other. In this case, holes 40 and 35-38 are visible in the walls 46 and 48, as well as holes 50 and 51 are in the walls 47 and 49. Holes 35-39 and 40- 44 were not yet visible in FIG. 4a.

If you stretch the side strips 30, 31 in the direction of the arrows 52, 53, then again the form shown in figa appears. The holes 35-38 and 40 then lie directly above the walls 54 and 55, respectively, while the holes 50, 51 lie directly opposite the walls 56, 57.

Figure 5 shows the right half of the following example of the implementation of the ventilation tape 60 from a non-integral, flexible material, namely in front view. It can be seen that the middle strip 61 is bent down at its ends and forms first a wall 62, then a wall 63, then a wall 64, then a wall 65, then a wall 66 and finally passes into a side strip 67. Where the wall 65 lies in the middle strip 61, a connection may be made by welding or by another method. Accordingly, the same applies to the fit of the wall 63 to the side strip 67. The holes in the walls 62, 64, 66 in the view of FIG. 5 are not visible.

In contrast to the previous exemplary embodiments, the exemplary embodiment of FIG. 5 has two ventilation ducts 68, 69.

The ventilation tape 60 shown in FIG. 5 is again shown in FIG. 6 in side view. While visible holes 70-74 in the wall 62.

Figure 7 shows the following variant of the ventilation tape 75. The flexible ventilation tape 75 has one ventilation channel 76, the middle strip 77 of which passes into an inclined wall 78 with holes (grooves) 79, 80.

On the contrary, the side strip 81 passes into an inclined wall 82 with openings 83, 84. The ventilation channel 76 in this case has a trapezoidal cross-section.

On Fig presents the following variant of the flexible ventilation tape 85 with two ventilation channels 86, 87. The walls 88-90, which form the ventilation channels 86, 87, are set obliquely, so that they form triangles. You can see the holes 91, 92 in the wall 90, the hole 93 in the wall 89 and two holes 94, 95 in the wall 88. Additionally, in the ventilation channel 87 you can still see obstacles 96 and 97 and 98, respectively, which are located behind the holes 93 and 91 and respectively 92. Thus the labyrinth is obtained. The resulting air flow is indicated by arrows 100-104. The middle lane is indicated as 105, while the side lane is indicated as 106.

Figure 9 shows another ventilation tape 107, which also has two ventilation channels 108, 109 and is made as a ventilation tape 85.

Figure 10 presents another ventilation tape 110, which is laid out in the area of the ridge of the roof. The middle strip 111 is located on the ridge beam 122, and the ventilation tape 110 is sealed with a ridge roof tile 112. In the following, the right half of the ventilation tape 110 is described in more detail.

The middle strip 111 forms the first straight section 114, which then passes at an angle of about 90 degrees to the left and forms the wall 115. Then, the middle strip 111 after turning to the right runs parallel to the upper side of the roof tile 113, and it forms the wall 116. After a second left turn, the middle strip 111 forms a wall 117 so that after the next left turn, it runs parallel to the straight section 114. The side strip 118 runs first parallel to the surface of the roof tile 113, so that it then turns upward run into a section 114 of the middle strip 111. This forms a wall 119, which, together with a straight section 114 and a wall 115, forms a ventilation duct 120. The next ventilation duct 121 is formed by walls 117, 115, 116. There are openings in walls 117, 115 and 119, which are not visible in FIG. 10. Reference numbers 122, 123 and 124 indicate the ridge beams that bear roof tiles 112, 113 and 99. The left area of the ventilation tape 110 shown in FIG. 10 is formed mirror symmetrically to the right area and therefore is not described in more detail.

The representation of FIG. 11 corresponds to the representation of FIG. 10, unless it is a perspective view. In this case, holes 125-127 are visible in the wall 117, as well as hole 128 in the wall 115 and hole 129 in the wall 119.

The designation “ventilation duct” used above includes not only one longitudinally extending ventilation band 110, but also an open ventilation duct 120.

On Fig presents a fragment from the area 130 of the slope of the sloping roof. In this case, three parallel rafters 131-133, passing in the direction of the ridge, as well as battens 134-136, which are mounted on the upper sides of the rafters 131-133, are visible. Perpendicular to the rafters 131-133 and the battens 134-136, the rails 137, 138 pass. Between the rafters 131-133 and the battens 134-136 there is a lower tie strip 139.

Due to this arrangement, two ventilated planes arise, a lower ventilated plane 179, as well as an upper ventilated plane 180. The melt water that has penetrated or seeped through is discharged along the lower ventilated plane 179. Moreover, the upper ventilated plane 180 supports the task of the lower ventilated plane 179 and further contributes to the rapid drying of the lower tie strip 139.

A fragment of the slope region 130 shown in FIG. 12 is shown in FIG. 13, namely, together with the ventilation tape 140. This ventilation tape 140 is constructed like the half of the ventilation tape 60 shown in FIG. 5. The side strips 141, 142, however, enclose angle of 90 degrees. Openings 146-149 are provided in the walls 143, 144, 145 of the ventilation tape 140 arranged parallel to each other. One side strip 142 lies on the front side 150 of the rafters 151, while the other side strip 141 lies on the battens 152 and hits the crossbar 153.

Further, in FIG. 13, it can be seen that the ventilation tape 140 is connected to the battens 152 and the rafter 151 with connecting elements, of which only two are designated 181, 182. With these connecting elements, for example, we can speak about nails. Although the ventilation tape 140 can be glued by its side strips 141, 142 to the rafter 151 and, accordingly, the battens 152, it is advantageous if the ventilation tape 140 is additionally bonded to the rafter 151 and, respectively, the battens 152 with connecting elements.

Moreover, the side strips 141, 142 may consist of only one material, or also of several materials located one above the other.

This ventilation tape 140 is made of essentially flexible material. This ventilation tape 140 may be made of airtight or at least partially breathable strip material. This material may be film-like or fabric-like. Organic material is preferably used as the material. If the material is similar to films, then thin plastic films, metal foils or also organic films, which have a thickness of up to about 1 mm, are used. Depending on the type of material, the ventilation tape 140 may be water repellent or may also be at least partially permeable.

Due to the fact that the ventilation tape 140 is made of flexible material, it can be in two different states. In the first state, in a compressed state, the ventilation ducts 176, 177 are not open. This happens if the ventilation tape 140 is folded. In the second state, uncompressed state, the ventilation ducts 176, 177 are open. This happens, for example, when unwinding the ventilation tape 140. Moreover, due to the use of certain materials for this ventilation tape 140, the ventilation channels 176, 177 when unwinding the ventilation tape 140 are independently opened. This happens, for example, if materials that have regenerative power are used for the ventilation tape 140.

Although the rectangular ventilation ducts 176, 177 are shown in FIG. 13, it also seems possible for the ventilation ducts 176, 177 to have a different cross-sectional shape when installed. It is thus possible, for example, for the ventilation ducts 176, 177 to have a trapezoidal, triangular or also similar to a blade cross-section in the installed state. Also, the holes (grooves) 146-149 can have different shapes. Thus, the holes 146-149 can be, for example, round, rectangular, triangular or U-shaped in shape. Moreover, this is not necessary, as shown in Fig. 13, that the holes 146-149 lying opposite each other are offset from each other. It is also possible that these holes lie opposite each other. If, for example, various types of openings are located in the ventilation ducts 176, 177, then water barriers may be located between these various types of openings. Additionally, the openings may be coated with an air-permeable non-woven fabric. In this case, the hole itself, however, remains breathable, however, as a result of this, the mass of the exchanged air will become less. This is advantageous, in particular, when you want to provide an air channel, which makes possible a more insignificant exchange of air without changing, however, the size of the holes. At the same time, with the same size of the holes remaining and their number unchanged, the air exchange can be regulated without necessarily providing a new ventilation tape. For this purpose, for example, you can simply put on the wall 143 non-woven fabric so that it covers the holes made as ventilation holes 146, 147.

The ventilation tape 140 shown in FIG. 13 is supplied as a roll. In this state, it is compressed so that the walls of the ventilation ducts 176, 177 lie flat on top of each other and the ventilation ducts 176, 177 are closed. An increase in volume does not occur. Such a roll is shown in FIG.

FIG. 14 shows a ventilation tape 183 provided for a slope region in a compressed state. In this case, you can see the first side strip 154 and the second side strip 155. The walls 156-158 of the ventilation tape 183 are lowered and extend almost parallel to the side strips 154, 155. These walls 156-158, as well as the side strips 154, 155, may consist of a flexible the substance of the material. Between the walls 156-158 are two ventilation ducts 187, 188.

Using forces that, respectively, in the directions of the arrows 159, 160, act on the first side strip 154 and the second side strip 155, the walls 156-158 are raised. With increasing stretching in the transverse direction of the ventilation tape 183, i.e. in the direction 159 and in the direction 160, approximately half of the maximum stretch is achieved, and the ventilation ducts 187, 188 of the ventilation tape 183 are partially open. This state can be seen in FIG. On Fig the state of the ventilation tape 183 is presented after maximum stretching.

Symbolized by arrows 159, 160 forces can be applied, for example, with two hands.

This ventilation tape 183 may be located, for example, in the area of the roof slope.

On Fig presents another ventilation tape 161, in which the walls are automatically installed when the ventilation tape 161 is unwound from a roll. Between the strips 162, 163 are the walls 164-166. Between the two walls 164-166 are respectively spring elements 167, 168, which produce forces on the strips 162, 163, namely in opposite directions.

These two ventilation ducts located parallel to each other can be located side by side, but also one above the other.

On Fig presents how the walls 164-166 due to the forces produced by the spring elements 167, 168 are on the bands 162, 163 almost vertically. At the same time, the ventilation ducts are wide open.

The spring member 167 is shown in FIG. 19 in a separate position. It can be seen that it has two arms 170, 171, which form a shape L. One arm 171 contains several teeth 172, 173, while the other arm 170 is a solid plane. The spring element 167 consists of an elastic spring material, which, after the end of the compressive force of the spring element 167 forces again occupies its original position.

In a compressed state, cf. 17, ventilation tape 161 may be wound onto a roll. In the winding process, a sufficient amount of force is applied to compress the ventilation pad 161. Thus, it is only necessary at the beginning of the formation of the roll to manually compress the end of the ventilation tape 161.

In Fig.20 shows a roll 175, and we are talking about coiled ventilation tape 140 according to Fig.13. With this ventilation tape 140, the side strip 141 is pressed against the side strip 142. Then, winding can begin.

With this roll 175, it turns out that in the rolled state, the openings 146-149 are closed, since the walls of the ventilation tape 140 are substantially compressed. In the collapsed state, there are no longer any ventilation ducts, since they are also compressed.
