Description

The present invention relates to a profile device in connection with a roof to form a roof ridge, and a method of producing a roof ridge with such a profile device, as appears from the introductory part of patent claims 1 and 11 respectively.

Known technique

On a conventional roof, the roof ridge is normally formed by a wooden ridge ridge on the roof trusses on a pitched roof, in order to, among other things, act as a fastener for screws or nails that are brought in through existing holes in the ridge pans that are laid over the roof ridge. The ridge pans usually need to be screwed or nailed in place so they don't come loose when it's windy or the like. Since wood is a living material, it follows that a conventional wooden ridge ridge can twist as well as the position of the top batten on each side of the ridge must be accurately measured before it can be nailed in place. It will also be heavy and uncertain to handle the ridge on the roof, which work requires good construction skills.

An alternative solution to a conventional ridge ridge is known, for example, in US-A1-2005/0239392 which, among other things, in Fig. 11 shows a ventilation device for a roof which consists of, among other things, a cloth that is attached to the outside of a centrally crossing board in the rafters . A support holder of a rigid material is placed on top of said table to support the central part of the cloth. The cloth is produced from a flexible material that transmits air, but not liquid. In one embodiment, the ends of the fabric are fixed under the loops and battens on top of the roof, in which additional vertical metal plates must be arranged within said ventilation fabric. As a result, the device becomes cumbersome to handle and requires a lot of time and skill when setting it up.

Purpose

Accordingly, the object of the present invention is to provide a device and a method that solves, among other things, the above-described problems as well as replacing the conventional wooden ridge ridge to provide the position of the upper batten by measuring and mounting as well as forming cover over the roof ridge, which allows free ventilation from the roof space out under the outer roof and thereby achieve the following advantages compared to a conventional solution:

-Great time saving

- High quality

-Optimum ventilation of the roof space

- Easy to assemble

- Easy to work with

- Low weight

-Reduce the requirement for necessary knowledge during assembly

- The same product can be used for brick, as well as concrete and sheet metal roofs.

The invention

These purposes are achieved with a device and a method according to the characterizing part of patent claims 1 and 11, respectively. Further advantageous features appear from the respective independent patent claims.

According to the present invention, the horizontal position of the upper lath is now achieved free of charge thanks to said lath being placed with its upper edge side turned obliquely upwards close to the right-angled outer profile part. After that it is only necessary to measure down to the lowest edge part of the roof in order to be able to divide the distance into correct section distances for the laths to be nailed in place across the loops to match the size and planned spacing of the roof tiles when the same are placed out on the aforementioned barges.

EP 0427575 relates to a profile (1) which has angled parts (3) to be screwed into the loops. Nevertheless, an angled outer part is missing for attachment to the battens.

US 61228870 A relates to a profile where the bent parts (16, 16A) of the profile rest on the loops (74) and that the laths (102) rest on the said bent profiles (16, 16A). In this connection, the profile also lacks such a right-angled lower batten support.

The patent abstracts from Japan, Vol 2000, no. 21 3 August 2001 (2001-08-03) and JP 2001 90288 A (Sahara Buresu Kogyo KK), 3 April 2001 (2001-04-03) summary concerns a ridge profile that clearly differs from the invention, and therefore it will not in at all be commented on in this phase.

Finally, EP 1304422 relates to a profile for a roof, but this is designed in a completely different way and is intended to work in a completely different way to the present invention. For example, barges are positioned highest on the ridge, see Fig. 4.

Accordingly, the present invention meets a need for a ridge shaft intended to provide good ventilation and at the same time is easy to assemble. The ridge ridge consists of a profile arranged to form the ridge of a pitched roof and thereby replace the conventional ridge ridge, which generally consists of a wooden connecting board attached to the top of the trusses.

The Møneåsen according to the present invention consists of a profile device which is produced from one or more rigid materials and which has a number of different parts which are angled in relation to each other.

With the help of a profile according to the present invention, the work of positioning and attaching a ridge ridge becomes very simple and entails large time savings at the same time that the quality of the ridge ridge increases in comparison with previously known ridges (beams).

The profile will be cheap to produce and very easy to assemble, which will lower the requirement for knowledge and reduce the time spent when assembling it.

Detailed description of the invention

Even if the invention below applies to roofs that are covered with roof tiles, it must be understood that essentially the same profile device can be used for brick, concrete or sheet metal roofs.

Figures 1 and 2 show a sectional drawing of a ridge which has a profile device 30 which comprises 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, of which perspective drawings are shown in figures 3 and 4, is produced from a rigid material, preferably plastic or metal sheets or a combination thereof, and in this embodiment the profile is composed of pairs of substantially vertical sides 3a, 3b which are placed in a mutual distance A from each other and has ends la and lb and a flat upper part 4 which connects the said two sides 3a, 3b with each other. Each side 3a, 3b of the profile 10 has two parts la, 2a; lb, 2b which are angled in relation to the sides 3a, 3b. The areas 2a, 2b between the ends la, lb and the sides 3a, 3b form an attachment part 2a, 2b each which is attached to a loop 8 on the top side 8a thereof on the respective sides I, II of the ridge 50 on the roof. The batten 9 lies with its upper side 9a against the ends la, lb of the profile 10, which in this embodiment is angled in relation to the sides 3a, 3b and the fastening parts 2a, 2b of the profile 10. The ends la, lb are angled 902 in relation to the fastening parts 2a, 2b and abut against the laths 9 and thereby the laths 9 are protected from possible water or the like that runs down from the sides 3a, 3b to the profile 10.1 instead of is possible water gathered up against the angled ends la, lb and evaporates eventually away. The ends la, lb can also be in line with the attachment parts 2a, 2b, but do not provide the same protection against moisture.

The strips 60 between the different parts 1, 2 and the sides 3 can preferably be formed by jointable plastic hinges of a known type, which are formed by compression of the plastic material in the longitudinal extent of said strips.

A seal 20 is arranged on the outside of the profile 2. The seal is attached to the profile by means of a protrusion 6, which is inserted into a recess 5 which has internal 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 into place into the recess. The aforementioned seal 20 can also preferably be made of plastic and/or metal materials, and can easily be cut to the desired length by cutting using, for example, a saw.

On the outside of the seal 20, a ridge pan 11 is placed, which is attached to the profile 10 and the seal 20 by means of, for example, screws or another usable fastening device. The sides 7a, 7b of the seal 20 are arranged between the ridge pans and 11 and the top roof tile 12 on the roof, and the respective edge parts 11A, 11B of the ridge pans are arranged to rest against the top side of the top row of the roof tiles 12.

An underlying stopper 13 located at the upper edge part of the roof tiles 12 is arranged to cooperate with the lath 9 and its edge facing the ridge and thereby prevent the roof tiles 12 from sliding down along the sloping plane to the roof 31.

When roofing a conventional roof, the support beams 100 are covered with, for example, approximately 20 mm rough panel with unplaned good side 500, alternatively in light false ceilings followed by a so-called mosquito net and underlay cardboard at, for example, a ventilated ridge. The wooden ridge is then attached and the loops are put in place. Then, when the battens and tiles should be put in place, a roofer has to climb up the ridge with a number of tiles to measure exactly and decide in what position the battens should be placed in order for the tiles and ridge pans to cover the entire roof. This procedure is simplified by using a profile 10 according to the invention. Instead of nailing a wooden ridge ridge, a profile 10 is placed over the ridge on the roof. The fastening parts 2a, 2b are placed against the loops 8, which in that connection are already nailed to 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 parts 2a, 2b which are angled in relation to the sides 3a, 3b on the profile 10, and fasten the fastening parts 2a, 2b with nails, screws or a similar fastening device in the trusses 100 through the loops 8. Then a lath 9 is pressed against the angled parts la, lb on the profile 10, so that these lie substantially in close contact with each other. Preferably, the angled parts la, lb on the profile 10 have an essentially perpendicular extent in relation to the extent of the attachment parts 2a, 2b. The aforementioned parts la, lb are arranged to be placed against the sides of the laths 9, to collect condensation and liquid that has run down along the sides 3a, 3b of the profile 10, thereby preventing the laths 9 and loops 8 from being exposed to unnecessary moisture. Then, on top of the profile 10, the ridge pans 11 are placed which can be attached directly to the profile 10 by means of screws or similar fastening means. Preferably, the profile 10 has a flat top side 4 formed of a material and in such a way that screws can be easily fixed in the top side 4.

By using a profile 10 according to the invention, all ventilation is carried out in the space between the battens and the false ceiling, which results in a quick and efficient ventilation from the ceiling space out under the outer ceiling.

As mentioned above, the profile 10 is preferably produced from plastic, for example extruded plastic, which results in a light profile 10 which can be made in long lengths, and which, despite that, the roofer can take with him onto the roof without any problem . The profile can also be produced from metal, preferably a treated light metal which is easy to handle and which is resistant to external influences in the form of liquid. Possibly the top side 4 of the metal profile 10 has to be processed in some way to allow a screw to be fixed in a required way. Preferably, the profile 10 has certain specific dimensions so that the upper batten 9 is to be positioned at the intended distance from the ridge. A certain flexibility should also be present in the profile 10, so that minor adjustments to 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 produced in one piece with the strips 60 or bends located at fixed locations which form the boundaries between the sides 3a, 3b and the top plate 4 as well as the fastening parts 2a, 2b. Stripes 60 or bends also form boundaries between the attachment parts 2a, 2b and the ends la, lb. Additional strips or bends can also be found on the profile 10 to provide more angled parts. The aforementioned strips 60, as has been mentioned above, form pivot joints for the various parts 1a, 2a; lb, 2b and pages 3a, 3b.

According to an alternative embodiment, the profile 10 is produced from a plurality of composite parts. The various parts of the profile 10 can, for example, be put together by welding, soldering or some other form of joining. The various parts can be of different materials particularly suitable for making up a specific part of the profile 10.

Possibly a seal 20 (see Figures 5-7) can be included in said profile arrangement 30 and be connected to the profile 10 to reduce the occurrence of snow and water in the area between the profile 10, the ridge pan 11 and the upper roof stone 12. The seal 20 is preferably placed on the profile 10 by pressing down the protrusions 6, which are located on the seal 20, into the recess 5 in the top side 4 of the profile 10.1 this example, the protrusions 6 are serrated to be easily fixed in the recesses 5, which in this example are equipped with small protrusions along the inside of the recesses 5 to make it possible to press the seal 20 smoothly into place over the profile 10 at the same time as the seal 20 is then held in this position.

According to a preferred embodiment, the sides 7a, 7b of the seal 20 have vertical slits 61, which means that the sides 7a, 7b are shaped according to the shape of the roof tiles 12. This means that the seal 20 also bumps up against the valleys in the roof tiles 12 and protects against debris, snow and rain that can otherwise blow in between the ridge pans 11 and the roof tiles 12. Above all, the aforementioned seal is intended to prevent birds and other animals from getting under the roof and building nests or dens there, thereby deteriorating the condition of the roof.

In Fig. 8, an alternative embodiment of a seal 21 is shown. At one end 21a thereof, said seal is pressed between the underside of a roof tile 12 and a batten 9, as well as at the other end 21b thereof between the top side of the roof tile 12 and the underside of the ridge pan 11.

The profile device 130 shown in figures 9 - 13 is in principle the same as the profile device 30 shown in the other figures, apart from certain details. Thus, water stop 150, for example in the form of form-fitting blocks, is arranged in said angled parts la, 2a; lb, 2b of the said sides 3a, 3b of said profile 110. Fixing screws etc. 151 can be received therein for fixing said profile 110 on the roof ridge as above. The main purpose of said water stop 150 is to stop water, which has possibly accumulated in the angled parts, from flowing further down the inner ceiling, but now the water is instead stopped and stands there until it evaporates.

A connecting part 160 is arranged to connect the respective two sides 3a and 3b of the profile with each other, between said angled parts 1a, 2a; lb, 2b and the upper part 104 of the profile. The profile 110 is thereby stiffened.

A seal 120 which is preferably arranged with a so-called gull wing shape and which is equipped with grooved outer sides 107a, 107b, can be attached to said profile 110 on the top side 104 thereof by means of suitable means, for example a groove-shaped projection 106 and channel-shaped recess 105. The width B on the aforementioned top side 104 and the middle part 170 of the seal are substantially similar to each other. The design example according to Figures 9-13 should have greater stiffness and strength than the examples shown earlier.

The nature and function of the invention should be clear from what has been said above and shown in the drawings, and the invention is naturally not limited to the embodiments described above and shown in the attached drawings. Modifications are possible, the seal 20 need not, if present, for example, consist of a separate part, but can be integrated into the profile 10. Under certain conditions, certain parts of the profile can also be produced from non-rigid material . Further modifications are possible, especially when it comes to the nature of the various parts, or by using corresponding techniques, without moving away from the protection area of the invention, as defined in the patent claims.
