Description:

An arrangement and a process at a roof ridge

Technical Field

The present invention relates to a profile arrangement in connection with a roof in order to form a roof ridge on a pitched roof having a number of counter battens or the like, which arrangement is formed of a profile that has sides having ends and is manufactured of a stiff material.

Prior Art

On a conventional roof, the roof ridge of the roof trusses of a pitched roof is normally formed of a ridge purlin of wood, in order to, among other things, work as an abutment for the screws or nails that are brought in through existing holes in the ridge tiles that are laid over the roof ridge. Ridge tiles usually need to be screwed or nailed in place in order not to come loose when blowing and the like. Since wood is a living material, the conventional ridge purlin of wood entails that said ridge purlin may warp as well as that the position for the upper batten on each side of the ridge also has to be accurately measured before it is nailed in place. It also becomes heavy and unsafe to handle the ridge purlin up on the roof and which work requires good construction knowledge.

An alternative solution to a conventional ridge purlin is, for instance, known by US-A1-2005/0239392 , which, inter alia, in Fig. 11 shows a ventilating arrangement for a roof composed of, among other things, a cloth that is fastened outside a central transverse board in the roof trusses. A support rest of a stiff material is applied on top of said board in order to support the central part of the cloth. The cloth is manufactured from a

flexible material that transmits air but no liquid. In one embodiment, the ends of the cloth are fastened under the counter battens and battens of the top roof, wherein additional vertical metal plates have to be arranged inside said ventila- tion cloth. Thereby, the arrangement becomes elaborate to handle and requires much time and skill upon the erection.

Summary of the Invention Hence, the object of the present invention is to provide for an arrangement and a method that solve, among other things, the above-mentioned problems as well as to replace the conventional ridge purlin of wood and provide the position of the upper battens upon measuring and mounting as well as form a hood over the roof ridge, which permits free venting from the roof space out under the outer roof and thereby gain the following advantages in comparison with a conventional solution:

- Great time saving.

- High quality. - Optimum roof-space venting.

- Easy to mount .

- Easy to work.

- Low weight .

- Lowers the knowledge required upon mounting. - The same product may be used for clay as well as concrete and sheet -metal roofing, etc.

Said object is attained by means of an arrangement and a method having the features defined in the independent claims 1 and 11, respectively.

Additional embodiments of the invention are defined in the appurtenant dependent claims 2-10 and 12, respectively.

According to the present invention, the horizontal position of the upper batten on the roof is now obtained for free thanks to said battens being placed with the upper edge side thereof turned obliquely upward tight against the right-angled outer profile portion. After that, it is only needed to measure down to the lower edge portion of the roof in order to then be able to divide the distance into correct partial distances for the battens to be nailed in place transverse to the counter battens so as to fit to the size and intended distance of the roof tiles when the same are set out to rest on said battens.

EP 0427575 Al relates to a profile (1) having angled portions (3) for screwing in counter battens. However, an angled outer portion for the abutment against battens is lacking.

US 61228870 A relates to a profile where the bent portions (16, 16A) of the profile rests on counter battens (74) and that transverse battens (102) rests on said bent profile (16, 16A) . In that connection also, the profile lacks such a right-angled lower batten support .

Patent Abstracts of Japan, Vol. 2000, no. 21, 3 August 2001 (2001-08-03) & JP 2001 90288 A (Sahara Buresu Kogyo KK) , 3 April 2001 (2001-04-03) abstract relates to a ridge profile that clearly differs from the invention, and therefore it is not at all further commented on at this stage.

Finally, EP 1304422 Al relates to a profile for a roof, but this is formed in an entirely different way and is intended to work in an entirely other way than the present invention. For instance, battens become positioned highest up at the ridge, see Fig. 4.

Accordingly, the present invention meets a need for a ridge purlin intended to provide good ventilation and that simultaneously is easy to mount. The ridge purlin consists of a profile that is arranged to form the roof ridge on a pitched roof and thereby replace the conventional ridge purlin, which, generally seen, consists of a connection board of wood that is fastened in the top of the roof trusses.

The ridge purlin according to the present invention consists of a profile arrangement manufactured from one or more stiff materials and that has a number of different portions that are angled in relation to each other.

By means of a profile according to the present invention, the work of positioning and fastening a ridge purlin becomes very simple and entails a great time saving at the same time as the quality of the ridge purlin increases in comparison with previously known girders .

The profile will become inexpensive to manufacture and very easy to mount, which will lower the knowledge required and decrease the time-consumption upon mounting of the same.

Detailed Description of the Invention Even if the invention below will relate to roofs that are covered with roofing tiles, it should be appreciated that substantially the same profile arrangement can be used for clay, concrete and sheet-metal roofing.

Figs. 1 and 2 show a cross section of a crest having a profile arrangement 30 comprising a profile 10 according to a preferred embodiment of the present invention. Only one side of the roof 31 is shown in this figure. The profile 10, perspective views of which are shown in Figures 3 and 4, is manufactured of a stiff material, preferably from plastic or sheet-metal or a combination thereof, and in this embodiment, the profile is composed of pair-wise substantially vertical sides 3a, 3b, which are situated at a mutual distance A from each other having ends Ia, Ib and a planar upper part 4 that interconnects said two sides 3a, 3b with each other. Each side 3a, 3b of the profile 10 has two portions Ia, 2a; Ib, 2b, which are angled in relation to the sides 3a, 3b. The areas 2a, 2b between the ends Ia, Ib and the sides 3a, 3b form a fastening portion 2a, 2b each, which are fastened on counter battens 8 on the topside 8a thereof on the respective side I; II of the ridge 50 of the roof. Battens 9 lie with the upper side 9a thereof against the ends Ia, Ib of the profile 10, which in this embodiment are angled in relation to the sides 3a, 3b and fastening portions 2a, 2b of the profile 10. The ends Ia, Ib are angled 90° in relation to the fastening portions 2a, 2b and abuts against the battens 9, thereby protecting the battens 9 from possible water or the like that runs down from the sides 3a, 3b of the profile 10. Instead, possible water is accumulated against the angled ends Ia, Ib and

evaporates after a while. The ends Ia, Ib may also be aligned with the fastening portions 2a, 2b, but give, however, not the same protection against moisture.

The scorings 60 between the different portions 1, 2 and the sides 3 may preferably be formed of articulatable plastic hinges of known type, which are formed by compression of the plastic material at the length extension of said scorings.

Outside the profile 10, a seal 20 is arranged. The seal is fastened to the profile by means of a projection S 1 which is inserted into a depression 5 having interior fastening means located in the upper part 4 of the profile 10. The fastening means are preferably formed in such a way that the seal 20 can be pressed in place into the depression. Also said seal 20 may preferably be made of plastic and/or metal materials, and can easily be cut in desired lengths by cutting-off by means of, for instance, a saw.

Outside the seal 20, then a ridge tile 11 is located, which is fastened in the profile 10 and the seal 20 by means of, for example, screws or any other suitable fastening member. The sides 7a, 7b of the seal 20 are arranged between the ridge tile 11 and the uppermost roofing tile 12 of the roof, and the respective edge portions HA, HB of the ridge tiles are arranged to rest against the topside of the uppermost row of the roofing tiles 12.

A subjacent stop lug 13 situated at the upper edge portion of the roofing tiles 12 are arranged to co-operate with the batten

9 and the edge surface thereof turned against the roof ridge and thereby prevent the roofing tiles 12 from sliding down along the leaning plane of the roof 31.

Upon roofing of a conventional roof, the supporting beams 100 are covered with, for instance, approx. 20 mm tongued and grooved boards 500, alternatively in light under-roof, followed by a so-called mosquito net and underlay felt at, e.g., a ventilated ridge. Next, the ridge purlin of wood is fastened, and the counter battens are laid in place. Then, when the battens and the roofing tiles should be put in place, a roofer has to climb up on the ridge with a number of roofing tiles so as to accu- rately measure and determine in which position the battens should be placed in order for the roofing tiles and the ridge tiles to cover the entire roof. This procedure is facilitated by using a profile 10 according to the invention. Instead of nailing a ridge purlin of wood, a profile 10 is placed over the ridge of the roof. The fastening portions 2a, 2b are laid against the counter battens 8, which in that connection already are nailed on the roofs, and since the profile 10 has a specific shape, a roofer only needs to put the profile 10 in place, with the fastening portions 2a, 2b that are angled in relation to the sides 3a, 3b of the profile 10, and fasten the fastening portions 2a, 2b by nails, screws or similar fastening members in the roof truss 100 through the counter battens 8. Next, a batten 9 is pressed up against the angled portions Ia, Ib of the profile 10, so that these lie substantially in close contact against each other. Preferably, the angled portions Ia, Ib of the profile 10 have a substantially perpendicular extension in relation to the extension of the fastening portions 2a, 2b. Said portions Ia, Ib are arranged to be applied against the sides of the battens 9, in order to collect condensate and liquid that have run down along the sides 3a, 3b of the profile 10, and thereby prevent the battens 9 and counter battens 8 from being exposed to unnecessary moisture. Then, on top of the profile 10, the ridge tiles 11 are laid, which may be fastened directly in

the profile 10 by means of screws or similar fastening members. Preferably, the profile 10 has a planar topside 4 formed of one material and in such a way that a screw easily can be fastened in the topside 4.

By using a profile 10 according to the invention, all venting is carried out in the space between the battens and the under-roof, which entails a quick and efficient venting from the roof space and out under the outer roof .

As has been mentioned above, preferably the profile 10 is manufactured of plastic, for instance extruded plastic, which entails a light profile 10 that can be made in long lengths and that a roofer, in spite of that, without any problems can carry up on the roof. The profile may also be manufactured from a metal, preferably a treated light metal that is simple to handle and that is resistant against external actions in the form of liquid. Possibly, the topside 4 of a profile 10 of metal has to be processed somehow to allow a screw to be fastened in the req- uisite manner. Preferably, the profile 10 has certain determined dimensions in order for the uppermost batten 9 to become positioned at the intended distance from the roof ridge. Certain flexibility should also be present in the profile 10, so that minor adjustments of the shape of the profile 10 can be made when the roofer is on the roof.

According to a preferred embodiment, the profile 10 is manufactured integrally with scorings 60 or bendings situated on fixed locations, which constitute borders between the sides 3a, 3b and the top part 4 as well as the fastening portions 2a, 2b.

Scorings 60 or bendings also constitute borders between the fastening portions 2a, 2b and the ends Ia, Ib. Additional scorings or bendings may also exist on the profile 10 to provide

more angled portions. Said scorings 60, such as has been mentioned above, form pivot joints for the different portions Ia, 2a; Ib, 2b and the sides 3a, 3b.

According to an alternative embodiment, the profile 10 is manufactured from a plurality of composed parts. The different portions of the profile 10 may, for example, be joined to each other by welding, soldering or any other form of joining. The different parts may be of different materials particularly suit- able to constitute a certain portion of the profile 10.

Possibly, a seal 20 (see Figures 5-7) may be included in said profile arrangement 30 and be connected to the profile 10 in order to decrease the presence of snow and water in the area between the profile 10, the ridge tile 11 and the uppermost roofing tile 12. The seal 20 is preferably applied to the profile 10 by pushing down projections 6, present on the seal 20, in a depression 5 in the topside 4 of the profile 10. In this example, the projections 6 are serrated so as to be easily fas- tenable in the depressions 5, which in this example are provided with small projections along the insides of the depressions 5 in order to enable to push the seal 20 smoothly in place above the profile 10 at the same time as the seal 20 then is retained in the position thereof.

According to a preferred embodiment, the sides 7a, 7b of the seal 20 have vertical slots 61, making the sides 7a, 7b of the seal 20 to become shaped according to the shape of the roofing tiles 12. This makes that the seal 20 also abuts against the valleys of the roofing tiles 12 and protects against litter, snow and rain, which otherwise may blow in between the ridge tiles 11 and the roofing tiles 12. Above all, said seal is intended against birds and other animals to get in under the

roofing and build nests or holes there, and thereby deteriorate the condition of the roof.

In Fig. 8, an alternative embodiment of a seal 21 is shown. In one end 21a thereof, said seal is squeezed in between the underside of the roofing tile 12 and a batten 9, as well as in the other end 216 thereof between the top side of the roofing tile 12 and the underside of the ridge tile 11.

The profile arrangement 130 shown in Figs. 9-13 is in principle the same as the profile arrangement 30 shown in the other figures, apart from certain details. Thus, water stops 150, for instance in the form of shape-adapted blocks, are arranged in said angled portions Ia, 2a; Ib, 2b of said sides 3a, 3b on said profile 110. Fixing screws, etc., 151 may be received therein for fastening said profile 110 on the roof ridge as above. The main object of said water stops 150 is to stop water, which possibly is accumulated in the angled portions, from running further down along the inner roof, but now the water instead being stopped and staying until it evaporates.

A connection part 160 is arranged to connect the respective two sides 3a, 3b of the profile with each other, between said angled portions Ia, 2a; Ib, 2b and the upper part 104 of the profile. Thereby the profile 110 is stiffened.

A seal 120, which preferably is arranged with a so-called gull- wing shape and which is provided with slotted outer sides 107a, 107b, is fastenable to said profile 110 on the topside 104 thereof by means of appropriate means, e.g., a rail-shaped projection 106 and groove-shaped depression 105. The width B of said topside 104 and seal intermediate part 170 is substantially equal to each other. The embodiment example according to Figs.

9-13 should have greater stiffness and strength than the examples previously shown.

The nature and the function of the invention should have been clear from what has been mentioned above and shown in the drawings, and the invention is naturally not limited to the embodiments described above and shown in the accompanying drawings. Modifications are feasible, the seal 20 does not need to, if such a one is present, for example, consist of a separate part but may be integrated in the profile 10. Under certain prerequisites, certain parts of the profile could also be manufactured from a non-rigid material. Further modifications are feasible, particularly as for the nature of the different parts, or by using an equivalent technique, without departing from the pro- tection area of the invention, such as it is defined in the claims .
