Description

Roof ridge sealing strip

The invention relates to a roof ridge Sealing strip having å center strip which is securable to a roof ridge lath and in particular is provided with air passage openings, and having side strips, situated on both sides of the center ship, whose bendable and extendable edge areas conform to the wavetiikesshape of the rooting panels in a use position as a result of a force which develops when the center strip Is secured to the roof ridges: DE 10 2005 022 940; 41 describes a roof ridge sealing strip having a 0 shape. The U-shaped web has air passage openings, and forms a center strip which is sfcurable to a roof ridge lath. The two U-shaped legs form spring bars which extend transversely with respect to the: direction of extent of the roof ridge sealhg ship. The spring bar's are covered on both sides with a nonwoven which has folds extending transversely with respect to the direction of extent: of the roof ridge seating strip, lire edge area of the two side strips which is formed in this way is thus able to bend, and also to extend in the direction of extent, so that the edge aria maf conform to the Wave-like shape of the roofing; panels. Adhesive beads> such as those required for a roof ridge strip according to DE 199 26 212 Λ1, fpr example, may fee dispensed with. DE 2002341301, EP 1:284330 A1 and W02004/022878 A1 show generic roof ridge sealing strips.

In order to apply the spreading force by means of which the edge areas; are; |)fnt and extended, the center strip must Be secured: fey applying a Éking; force to the roof ridge lath. This is achievedfey means: of nails of staples. Bor this purpose, the U-shaped roof ridge sealing strip Is placed with its center strip on the roof ridgl lath, the edge areas Of the side Strips being supported on the: crests of the: roofing panel. The center strip is situated at a distance from the roof ridge lath. During installajtiqm the center strip is pressed onto the roof ridge lath and secured there fey nails. A fixing force thus develops which spreads apart the spring bars that are covered by nonwoven, so that the spring fears may also conform to the wave-like shape of the roofing panel.

Application of this spreading force requires a certain rigidity in the area of the transition zones between the Side strips and; the center strip, and sufficient elasticity of the strips per se. In order to roll up die known roof ridge sealing strips the U-shaped legs must he laid flat so that they lie in the same plane with the U-shaped web and assume a roll-up packaging position, in the process, the prestress stored in the elastic U shape must be overcome. The force required for this purpose must also be maintained in die rolled-up statp. This is achieved, for example, by prevehdmg the rolled-up roof ridge sealing strip from unrolling by use of strapping. If the strapping is loosened, the roof ridge sealing strip relaxes in the manner of an elastic spring, so that it springs back into the U shape; i.e., in the installed state presses with the U-shaped legs against the rooting panels. it is an object of the invention to improve a roof ridge sealing strip of the described type in terms of handling,

The object is achieved by the features mentionel in claim 1,. First and foremost, a hinge connection is provided between the center strip and the side strip, about which the side strip is pivotable from a rofl- up packaged position, rø which the side strip is in a flat position together with the center ship substantially free of stress, into the use position, In addition, retaining members are provided Which hold the side strip in the use position so as to impede pivoting. The spreading force, which is necessary so that the free edge of the side strip may conform to the waye-like shape of the roofing pands, may be introduced into the side strips via these retaining members. The retaining members thus form stiffening which may be overcome only by applying a certain force, this force being greater than the force required for the edge areas to conform to the wave-iike shape of the roofing panels. The hinge is preferably formed by a plug-in connection. The side strips and the center strip may be manufactured separately from: one another. One of the two strips his insertion slits into which tabs of the: respective other strip may be inserted. The two strips may be pivoted about the hinge axes formed by the tabs and slits, from the packaged position into the use position. The tabs may form offsets which in the packaged position pass through the slits withoutstress,Ihe two strips in the packaged position are then almost completely free of stress in a flat position. However, the flat position necessary for rolling up is also achievable when the two strips which may be engaged into one another each form flat bodies, be., lying in a plane, In the rolled-up state, flip: tabs and the edges of the slits are then under only slight stress, which, however, is much less than that in the prior art. The above-mentioned retaining members, which in the use position act on the side strips in a pivot-blocking manner in at least one direction, may be harmed by support latches, We insertion silts may extend in a curved manner. The edge pprdons on the inside of the curve may harm the support latches, which in the use position contact the tabs in a pivot-blocking manner. The outer sides of the curve of the slits face the edge of the center strip. The portions of the strip which adjoin the edge portions of the inserion slits m the inside of the curve act as support latches. In the packaged position., the center strip and the two side strips lie substantially in one plane, i.e., are only slightly inclined with respect to Ope another. The Mps engage in the insertion slits. The support latches overlap the root area of the tal^yand lie on a portion of the base portion of the side strip. The support latches lie on the side of the side strip facing the pivot direction in which die: side strip must be pivoted from the packaged position into the: use position. When the side strip pivots from the packaged position into He use position, the edge portion of the slit on the inside of the curve slides along the side strip, the spring latch formed by the edge portion on the inner side of the curve initially opposing folding out of the side strip, in a ptvptddocMng manner. If the side strip is pivoted up to a 90° position, the upright support latch reaches a dead center position. If the side strip is pivoted beyond this dead center position, the support latch snaps through the plane of the center strip onto the other side of the side strip, and then abuts against the broadside area of the tab, acting in. the opposite direction in a pivot-blocking manner. The side strip has thus been brought into the use position. If both side strips have been brought into; the Use position by this type of fold-out activation and snapping around of the support latches; a substantially p-shapei foif ridge sealing strip ispresent, as is blown from,.. DE 10 2005 022 940 A1 and which may he used as inscribed therein. The [roof ridge sfripj is folded out by hand, for which theseenter strip of the tuir oiled ropf ridge strip may already lie oh the roof ridge lift Little by little, each of the two side strips is then brought from the packaged position inlet the use position in which the side strips are held in a pivot-blocking manner. The edge areas of the side ships are then supported oh the wave crests of the roofing panels. The center strip is situated at a distance from the roof ridge lath. If the center strip is pressed down onto the roof ridge lath and secured there by nails or the like., a deformation force is applied to the side strips which causes the bendable and extendable edge areas to conform to the wave troughs and wave crests of the roofing panels. The edge areas are then subjected to a continuous action of force and ate in contact with the outer surface of the roofing :::pMek,:::: Alternatiæe^ or additional detent; meanssmay be provided to hold the tabs in the use position. These detent means may be detent hooks situated at the edge of the center strip. However, they may also be slits through which the tabs are to be threaded. The detent hooks engage behind the tabs in order to hold the tabs in a laterally protruding position. The roof ridge tile may be supported on tabs which laterally protrude in this manner. However, these detent means mav also bo provided instead of the above-mentioned support latches in order to pivotally fix the side strips ih fheiuse position, in one direction. The two strips may be made of an elastfe materiai. The material may be plastics or metal. A material which is UV-earable is preferably used. The edge areas of the side $tri|»nay be elongated. The edge areas of the side strips have a nmMpliciiy of incisions or spring biis extending transversely with respect to the direction of extent of the roof ridge seeing: strip. The edge area may hi enclosed by a nonwoven, The: nonwoven is preferably extensible in the direction of extent For this purpose, the nonwoven has folds, extending transversely with respect to thi direction of extent which are able to unfold when the edge area adapts to he wave-like shape of the roofing panels, when the distance between the spring bars increases due to bending and extension. The center strip has a jpplt^Kcity of air passage openings, preferably configured in; a sieve-like manner, through which die roof may be ventilated. By Use of the variant according to the invention of the combined snapping and Mocking effect of the support latches, a high pressure force of the edge areas of the side strips cm the surface of the roofing panels is achieved, so that the butyl adhesives on the side strip, otherwise used m the prior art, are not necessary. The Spring elements, which go into an active position which fixes the roof ridge sealing strip in a U shape only after fold-out from the packaged position into the use position, hold thy side strip in the packaged position in a Sat disposition which allows rolling up. In addition, the tabs of the side strips, which protrude through the center part from the inside to the outside toward the edge of the center part are bent The tabs may then interlock in transverse notches, formed by detent hooks, at the edge of the center part in such a way that an additional force effect results on the side strips due to this fixing. The engaging force with which the edge areas are pressed into the wave troughs of fhffpbfmg panels is thus ensured in a long-lasting manner.

Skeroplary embodiments of the mvehtiOn are explained below with reference hr appended drawings, which show the following;

Figure 1 shows a subsequent illitshatinn of the Cornpieteff unrolled roof ridge strip after pivoting of the two side strips from the packaged position into the use position;

Figure 3 shows the three individual parts of the roof ridge strip, and a partial area of the side strip in the separated state;

Figure 4 shows an illustration corresponding to Figure 3, in which the two side strips are joined together with the center strip;

Figure 5 shows a section according to the line V-V irt Figured;:

Figure 6 shows an illustration corresponding to Figure 2,, in which some of the tabs have been brought beneath detent hooks;

Figure 7 shows a section according to the line VII-VII in Figure 6; and

Figure 8 shows an illustration corresponding to Figure 7 with a mounted roof ridge tile, ail tabs having been pulled beneath detent hooks.

Figure 3 shows the three main components of the roof ridge strip:. The roof ridge strip is composed of a center strip 5 made of plastics. Two tows of air passage openings 7 extending in the longitudinal direction are punched into the center ship 5. Closely spaced slits 9, each extending on a curved line, are situated lit each case near the edge of the center strip 5. The carve apices of The curved slits 9 in each case face the edge of the center strip 5. The length of the carved slits 9 is greater than the distance between two adjacent curved slits 9.

Detent hooks 13 are present approximately at the location of each space between two curved slits 9, The detent hooks are formed by extensions on the edge side and have slits,

Two side strips 6 are provided. The side strips # are substantially identical, and likewise are made of plastics. Each side strip 6 forms a multiplicity of tabs 8 at its edge lacing the center strip 3, The width of the tabs 8 corresponds to the length of the cm ved slit §§

The; edge of the side; strip 6 opposite from the tabs 8 is enclosed by a non woven 14. The side strips 6 have incisions 12 in the edge portion enclosed by the nonwoven 14. Instead of a nonwoven. however, a metal foil or a plastics film which is pleated or pressed in a waved shape may be used. These incisions 12 define; parallel spring bars 11 which extend transversely with respect to the direction of extent of the side strip 6. The incisions 12 are open toward the edge b' of the side strip 6 so that the spring; bars .11 rrsay bo spaced apart from one another. The edge 6' may thus be reshaped info awaked shape, and is stretchable with regard |p its length. Ήιβ nbriwoven itself may be inelastic The nohwbven is folded or creped in the: direction of extent of the side strip 6, Tins results m a stretching reserve which allows the spring bars 11 to spread apart, ,4s a result of this stretching reserve, the edge 6' is able to conform to t%§ wave-Hfce shape of roofing panels 7,

In the manufacture of the roof ridge strip, the tabs B are threaded through the slits 9 from tire outside, resulting in the sfructure Illustrated in Figure 4, which may be rolled up according to Figure 1,

The tabs 8 may be formed as a flat extension of the base strip of 11½ side strip b, so that in the packaged position they assume a slightly angled position with respect to the center strip 5, as shown in Figure 1.

Alternatively, however, the tabs 8 may have an offset, as shown in Figure 5; la side strips 6 lie in a substantially flat poMtibh with respect to the center strip 5 so that tbs roof ridge stripTiay be rolled up.

Figures 1, 2, and 6 show the roof ridge area of a pitched roof. Roofing panels 2 lie on roof laths:#. A roof ridge lair 1 extends in the roof ridge area. The roof ridge strip is unrolled onto the roof ridge lath 1, as shown in Figure 1, arid nailed or stapled to the roof ridge lath. From the edge, the side strips 6 are then pivoted from the packaged position: illustrated in 'pigure ϊ |η|ρ: fhe use position illustrated in Figure 2. The tabs 8 stand: substantia!!!?' vertically upward. The side strips 6 extend substantial!} vertically downward. The center strip å Mas a vertical spacing from theitoof ridge lath 1.

When the side strips 6 are pivoted from the packaged position into the use position, the crest portions of the edges of the slit 9 on the inside of the curve slide along the underside of the side strip 6, Due to the curved shape of the slits 9 and the flatness of the tabs 8, the edge areas of the silts 9 assume a position outside the plane of extent of the center strip 5. if the side strip 6 is pivoted beyond a 90® angular position with respect to the center strip 5, the support latches 10 snap onto fhe other side of the center strip 5, and then occupy approximately the position illustrated in Figure 7. The slit edges On the inside of the curve then feti retaining members as Stippprt latches 10 in order to hold the side strips 6 in the use position in a pivot-blocking manner.

Figures 6 to 8 show that some, or in Figure 8, all, tabs 8 are hent outWardlyc The ends of the iaibs engage beneath the detent books 13.

Asa result of the tabs 8 which are shaped Into a curve arid held by the detent hooks 13, the side strip 6 is held in the use position to an additional extent.

The ceritef strip 5 is connected to fhe roof ridge lath 1 in the use f Ospon, This may be achieved by means of nails or staples. In the process, stress is exerted on the §ide strips. This stmm muses tM edge areas: 6' of the side strips 6 to spread apart laterally:,,, as shown in Figure 7. 'Fhe spring Pars 11 fan out will their ends tying against the wave-like shape of the roofing panels 2. fhe spreading force to be applied is less than the: retaining force applied fey tire support latches 10. The retaining force applied fey the support larches 10 may be overcome tty pivoting: the side strips 6 outwardly. The packaged position is thus achievable in a reversible uiahneh, ftye slits 9 extending in a curved shape, together with the tabs 8 which are inserted through the slits, form a hinge connection about which the side strip fe niay be pivoted with respect to the center strip 5.
