Field of invention

Windows and doors in a building are usually mounted in a recessed wall opening. The opening can, for example, be recessed in a concrete element, or a professional will build a wall in place, leaving room for windows or doors. The opening usually has a larger dimension than the outside of the window or door to facilitate assembly. The space formed then must be sealed and insulated. This is usually done by means of mineral wool strips, which results in time- consuming and monotonous work for a professional.

Description of prior art

Typically, window and door frames are made of different shapes of frame profiles, and in order to seal the gap between the wall and these frame profiles that are used today, rolls of caulking insulation, mineral wool strips, are pressed into the gap. First is a roll of mineral wool, then a roll of mineral wool coated with plastic. The plastic-coated roller is used to prevent moisture from entering the building. The invention sought to be patented should also have a similar conduction barrier deployed along the caulking insulation against the inside of the frame. There is also an alternative method of caulking which involves attaching a thin strip of insulation to the wall opening or the frame profile that, after a while, expands (for example CC-Fonsterdrev or T-Emballage). This work is carried out in place when mounting the frame profile. This alternative method, however, requires a similar operation that is comparable to the use of mineral wool. The professional must apply the insulation before mounting the frame profile, which means that time duration does not decrease significantly. On large construction sites with several hundred windows and doors to be caulked, the monotonous work with rolls of mineral wool often becomes tiresome.

Shoulder and neck can take a lot of damage, especially where the spaces are tight and the insulation can barely be pushed in. Perhaps it is only one professional who has to caulk all frames, which may take several weeks depending on the size of the construction site. The physical and psychological stress can then become great. The same work is repeated countless times and professionals can easily get tired and unmotivated. Mineral wool gives off dust when used. Professionals risk the inhalation of small particles of mineral wool, with potentially serious health consequences, unless no mouth protection is used. Professionals may not always use mouth protection; or they want to take a break from the mouth protection to get fresh air. All inhalation in rooms where caulking of mineral wool has taken place means to risk inhaling particles and dust.

Object of invention

Through the invention sought to be patented, the scope and character of the work is changed. It is proposed that the mounting of the prefabricated frame is combined with the simultaneous removal of protection. The caulking work is combined with the mounting of the frame and the required time is considerably less compared to push-in rolls off mineral wool. In addition, the caulking becomes even and tight in all directions. When pushing the mineral wool strips, there is a risk that the air gap that will usually appear between the wall and the frame against the fagade will be neglected because the professional pushes the strips too far. This problem is eliminated by the precise construction of the invention, where both the width of the air gap and the insulation can be regulated at prefabrication according to the desired dimensions. Construction companies can earn labor and, instead of conventional windows and doors, order windows and doors with a built-in so-called caulking device, i.e. the invention sought to be patented. Window and door manufacturers can in turn sell the products at a higher price, but at a lower cost than the construction company's expense for a professional's work with rolls of mineral wool. The invention enables economic gain for both window and door manufacturers and construction companies. Moreover, the caulking work becomes healthier for professionals, both ergonomically and motivationally, as well as the fact that the professional does not risk inhalation of dust from mineral wool. The health aspect and the ergonomic solution can in the long run be the greatest advantage of the invention. In practice, the conventional caulking method basically transforms into a more gentle, time and cost-effective method.

The present invention provides the opportunity to use the invention immediately when the prefabricated frame is mounted, the caulking device, and applying a completely new caulking method. Window and door manufacturers build the caulking device into the frame profiles used, already at the factory. A

professional then uses the caulking device and the caulking method in connection with the mounting of the finished frame in a building.

Description of the preferred embodiments

Fig. 1 thus shows a plan view of a prefabricated frame profile 1 a according to the invention with a caulking device comprising an insulation 2 as viewed from the transverse outer edge surface 3a of the frame profile 1 a. In this edge surface 3a there is provided a longitudinal recess 4a and a groove 5a arranged therein. The recess 4a is intended for placement of an elastic and/or

expandable caulking insulation 2. The caulking insulation 2 is fastened to the bottom of the recess 4a, for example with glue 6 or loosely placed in the recess 4a and then compressed and packaged by a protection 7a. A moisture barrier 8 in the form of, preferably, thin plastic or a foil is directly attached to the inside of the caulking insulation 2. Holes or recesses 9a are provided to enable fixation of the frame profile 1 a and can extend through both the caulking insulation 2 and the protection 7a.

Fig. 2 shows a cross section through the frame profile 1 a according to figure 1 with a caulking insulation 2 and a protection 7a. The protection 7a is held in position by inserting one of its inner longitudinal sides/edges 10a into and positioned in the groove 5a, while the other outer longitudinal side/edge 1 1 a is glued or otherwise secured in a loose manner directly to the transverse edge surface 3a of the frame profile 1 a. The outer longitudinal side/edge 1 1 a of the protection 7a may end in parallel with the inner side surface of the frame section 12a or protrude therefrom. The longitudinal outer side/edge 1 1 a of the protection 7a may also be attached in another suitable manner against the frame profile 1 a, and/or e.g. angled over its inner side surface of the frame section 12a. The groove 5a is advantageously cut from the frame profile 1 a by an angle of between 0 and 90 degrees relative to the transverse edge surface 3a of the frame profile 1 a, but preferably at an angle of about 45 degrees relative to the transverse edge surface 3a of the frame profile 1 . Likewise, the longitudinal inner side/edge 10a of the protection 7a should be angled in such a way that it fits properly into the groove 5a. Thus, the protection 7a and the groove 5a hook into each other and lock to each other, preventing the protection 7a from being pushed out of the expanding turntable 2. The reason that the inner longitudinal side/edge 10a of the protection 7a is arranged to hook into the groove 5a, while the other longitudinal outer side / edge 1 1 a is loosely attached to glue 6 or releasably attached otherwise, is to make it easy to remove the protection 7a when the frame profile 1 a is placed in its final position in the wall opening 13 during assembly work (see, for example, figure 3).

Fig. 3 shows a cross section through the frame profile 1 a in the same manner as figure 2, how the protection 7a can be disassembled and how the caulking insulation 2 then begins to expand. The construction forms the basis of the caulking device according to the invention and enables a simplified caulking method which proceeds as follows. When the frame profile 1 a is placed and fixed at its final attachment site, usually in a wall opening 13 with a slightly larger dimension than the frame/frame profile 1 a, the protection 7a is loosened at its glued or otherwise loosely attached longitudinal outer side/edge 1 1 a, in direction A in the figure. Here the protection 7a can protrude a few millimeters to simplify disassembly by then releasing the protection 7a with, for example, a hammer and/or a tool. The disassembly of the protection 7a then takes place by being displaced/pulled substantially across the transverse edge surface 3a of the frame/frame profile 1 a in direction B as seen in the figure.

It is also possible that the protection 7a ends equally with the inner side surface 12a of the frame profile for a more discreet packing of the caulking insulation 2. The compressed caulking insulation 2 begins to expand as soon as the protection 7a is pulled out of the inner, preferably 45° angled groove 5a, so that the gap between the wall opening 1 3 and the frame profile 1 a begins to fill. The protection 7a is completely removed and can be recycled.

Fig. 4 shows how the protection (not shown) has been completely removed, wherein the caulking insulation 2 fully expanded and completely filling the gap between the frame profile 1 a and the wall opening 1 3. The figure also shows the screw joint 14 which holds the frame profile 1 a in a fixed position in the wall opening 1 3.

Fig. 5 shows a cross sectional view of a further embodiment of the frame profile 1 b according to the invention with a caulking device. A groove 1 5a is here arranged in the inner side surface 1 2b of the frame profile 1 . The protection 7b is provided with a profile part 1 6a which fits into this groove 15a and which locks the protection 7b to the frame profile 1 b and prevents the protection 7b from being squeezed out of the compressed caulking insulation 2. This groove 1 5 may advantageously be used as attachment for, for example, a side-jamb or head-jamb extension for casing (not shown) when the protection 7b has been removed. A recess 4b in the frame profile 1 b is also provided here for accommodating the caulking insulation 2, but such a recess 4b may not necessarily be provided in the frame profile 1 (see Fig. 6).

In the embodiment of this figure, the longitudinal inner side/edge 1 1 b of the protection 7b is held in place against the frame profile 1 b by means of a profile part 16a. The profile part 1 6a is here engaged with the frame profile 1 b via the groove 1 5a, which allows the protection 7b to be fixed and locked against the frame profile 1 b. The protection 7b can easily be removed by displacing it or pulling it substantially in the transverse direction to the transverse edge surface 3b of the frame profile 1 b. The protection 7b is pulled more easily if it is provided with a flange 17.

A further fastening element 18a is arranged to hold the inner side/edge 10b of the protection 7b in position to compress the caulking insulation 2. This fastening element 18a is substantially shaped like a long strip which can advantageously be formed with a further attachment 19 intended for connecting an additional component (not shown), for example aluminum cladding intended for the outside of the frame/frame profile 1 b, which is a common option for many windows and door consumers. Thus, the fastening element 18a can be given two functions. The groove 15 may be used to attach an additional component (not shown) after the final assembly of the frame/frame profile 1 b, such as, e.g., an inner jamb extension for casing (not shown), in the form of, for example, a sheet metal lining or wood lining.

Fig. 6 shows a cross section through a further embodiment of a caulking device. The caulking device can here be designed in two outer parts, for example a detachably secured protection 7c and a lower part 20 between which the caulking insulation 2 is placed. Here the protection 7c is formed with a similar profile part 16b, as in figure 5, at its outer side/edge 1 1 c and holding the protection 7c fixed in the lower part 20. The inner side/edge 10c of the protection 7c is secured by a fastening element 18b.

Fig. 7 shows a portion of a window 20, and more particularly one of its corners 21 , and is provided with a caulking device. Two protection 7d is encountered here at the corner 21 of the window 20, and in this case the caulking insulation 2 is added and folded over the corner 21 , so that the gap between the window and the wall opening 13 is also isolated here. When using blocks under the bottom frame profile, the protection 7d can be advantageously made with recesses which provide space for these blocks (not shown). Fig. 8 shows a top perspective view of an upper part of a further embodiment of a frame profile 1 c according to the invention with a caulking device, in its assembled position. In this case, the protection 7e is partly arranged to be held in place in a groove 5b and also formed with a profile part 16c, which fixes the protection 7e in the frame profile 1 c by a groove 15b formed in the side of the frame profile 1 c. The protection 7e and the profile part 16c are made in one piece and may, for example, be made of plastic or metal. In order for the screw joint (not shown) not to obstruct the protection 7e upon disassembly, a U- shaped recess 9b may conveniently be provided in the protection 7e, especially if the screw joint 14 is located further into the frame profile 1 c.

Fig. 9 shows a top perspective view of a further embodiment of a frame profile 1 d according to the invention with a caulking device and wherein the protection 7f is halfway disassembled/pulled out with pliers. In this embodiment, the protection 7f is fixed by means of a plurality of clamps or fastening elements 18c distributed along the longitudinal inner side/edge 10c of the protection 7f and the longitudinal outer side/edge 1 1 d of the protection 7f is held fixed by a longitudinal profile part 16d which is arranged to be clamped in a groove 15c.

The object of the invention is to create a caulking device by means of a prefabricated frame profile 1 a-d with built-in insulation 2, thereby changing the conventional caulking method when assembling windows and doors, in particular, to achieve a more efficient, more profitable and gentler method. The caulking device is intended to be manufactured industrially by window and door manufacturers for further installation by companies at construction sites or individuals in their homes. Manufacturing this type of frame profile may require a reorganization of the manufacturing process. New machines and equipment may be needed and implemented in the factories. In the long run, however, the idea is that the effect will be financially profitable for all parties. Because the device is packing the caulking insulation, time and workload can be significantly reduced at construction sites. Due to the technical design of the packaging and the arrangement of the frame profile, the professional only needs to remove the protection from the inside of the frame profile for the work to be performed. As soon as the protection is removed, the caulking insulation extends along the wall side, and the gap is filled and thus becomes isolated. The method saves the professional contact with the caulking strips of mineral wool that may irritate skin and lungs when used. In addition, it is difficult to work economically. The elastic and/or expanding caulking insulation in the frame profile may instead be made of polyurethane, more specifically polyether (foam) or similar material with flexible and insulating properties, which does not irritate skin or lungs in the same unhealthy way. The nature of the material does not release dust or particles that are in danger of inhalation. Polyurethane has good building characteristics. The heat conductivity (k-value) can be as low as 0.025 W/(m- K), which can be compared with mineral wool having about 0.037 W/(m- K). The values may vary depending on how compact the material is sealed and what composition it has in manufacture, but polyurethane or polyether has at least as good properties as mineral wool when it comes to heat conductivity and insulating properties. The lower the k-value, the better the insulation ability. Fire class is compared according to Europe's classification system. For

polyurethane, it is between B - E, for smoke evolution s1 - s3, according to PU- Nordic. The composition of the material can of course vary, as can the classification. Polyether should hold a fire class around B, which gives the material a good protection. Mineral wool generally has fire classes A1 and A2, for smoke evolution s1 , which belong to the highest classes and best protection. However, insulation with mineral wool also adds the plastic-coated roller. This plastic is usually more flammable than mineral wool and has a lower fire class. The soundproofing ability of polyether is good and can be compared with mineral wool. Again, properties such as soundproofing ability depend on how tight the material is pressed and what composition the production gives. All in all, it can be said that polyether and polyurethane carry the desired building- technical properties which make the materials suitable for the caulking insulation of the present invention. Of course, other building materials can replace what constitutes the basis of the expanding caulking insulation. Mineral wool can be used advantageously with the invention, plastic-coated or not. Mineral wool particles should not be able to spread as much as when using conventional mineral wool strips. Possibly, the removal of the protection releases some particles, but in practice, only a fraction in comparison to conventional caulking with mineral wool strips. The prerequisite is that the material functions for the purpose of the invention and possesses desirable building-technical properties.
