Description

SUMMARY OF THE INVENTION

The present invention consists of a composite frames for the manufacture of doors and/or windows, which is applied in a door and/or window opening of a building and consists of at least one fixed rim (1), and at least one fixed leaf and/or at least one movable leaf, wherein the fixed rim and fixed or movable leaves are made of composite material.

FRAMEWORK OF THE INVENTION

Composite materials are materials formed by the union of other materials, thus obtaining a product with higher quality/mechanical properties. The synthesis of composite materials takes place with the mixture of compounds of different natures in order to obtain new properties for the materials. As it is a multiphase material, a composite exhibit in addition to the inherent properties of each constituent, intermediate properties that arise from the formation of an interfacial region. The phases of composites are called: i) composite matrix, which can have ceramic, polymeric and metallic origin; and ii) disperse phase, which generally has origin in fibers or particles that serve as filler.

The choice of this combination of materials relates to the following:

• • the aluminum, which will be the composite matrix, has excellent mechanical properties and excellent resistance to corrosion;
  • the wood, which will be the disperse phase, has excellent thermal and acoustic insulation properties; and
  • the polyurethane based adhesive is a good promoter of aluminum and wood bonding.

Thus, with the present invention we were able to obtain windows and/or doors frames with excellent mechanical properties and resistance to corrosion, which makes them to have an enormous durability, combined with the fact of having an excellent thermal and acoustic insulation, wherein these frames are not restricted to the dimensions of frames known in the state of the art as being the appropriate to be manufactured in wood.

In fact, in the current construction of all-wood frames it is not possible to manufacture openings with large dimensions or weights. With the present invention, that is, with this combination of materials, dimensions much larger than those known are achieved, being possible to manufacture large sized frames, such as 6 m² per leaf, and weights of approximately 300 kg per linear meter, which exceeds the current state of the art.

The fact that aluminum is combined with wood also makes it possible to stabilize warping and the problems of frames typically made only of wood and without a metallic structure inside it.

In turn, the fixed rim (1) can be fully integrated in the walls, ceiling or floor, and it is possible to see just at least one leaf, which has wood and glass in its constitution. The fixed rim (1), in turn, is made of aluminum and can be covered with wood in the part that is visible when the frame is mounted.

The present invention allows manufacturing frames in which only wood is visible. The front view of the vertical profiles can have a minimum of 18 mm and a maximum of 45 mm.

DESCRIPTION OF THE INVENTION

The frames, object of the present invention, presents in its constitution at least one fixed rim (1) and at least one leaf (2), which can be fixed or movable, and which is constituted, along its perimeter, by aluminum and wood elements, either skirting boards (5), vertical profiles (4) or handles (3). The union of wood to aluminum is executed by adhesive (10) and mechanical fittings (11)(13) between the wood profiles (3b)(4b)(5b) and the aluminum profiles (3a)(4a)(5a) of the respective elements, being perimetrically fixed to the leaves (2). Screws (12) can also be used, thus ensuring an excellent adhesion and durability of the wood and aluminum profiles sets.

The leaf (2) may contain a single or double or triple glass with thicknesses between 6 mm and 38 mm, or another type of panel in another type of material. The movement of the movable leaf (2) is done through sliding in a parallel or perpendicular plane in relation to the fixed rims (1). This movement is done with the help of at least one handle (3), which is formed by aluminum profiles (3a) glued to wood profiles (3b), wherein its fixing is executed through the adhesive (10) based on polyurethane and may additionally have screws (12). Moreover, there are mechanical fittings (11) both in wood profiles (3b) and aluminum profiles (3a) to ensure good alignment between them.

In a preferred embodiment, the invention presents at least one movable leaf (2) having at least one handle (3) and at least one vertical profile (4).

In another preferred embodiment of the invention, at least one movable and/or fixed leaf (2) has skirting boards (5), in the lower and upper part of the fixed rim (1), wherein these skirting boards (5) are formed by wood profiles (5a) that are glued and screwed to aluminum profiles (5b), wherein their gluing is executed through the adhesive (10) based on polyurethane. There are also mechanical fittings both in wood profiles (5b) and aluminum profiles (5a) to ensure good alignment between them.

The vertical profile (4) has several embodiments with various sections, wherein its smallest section is 30 mm and its largest section is 45 mm. The vertical profile (4) with the smallest section is the current state of the art for wood frames. The vertical profile (4) is formed by wood profiles (4b) glued to aluminum profiles (4a), wherein their gluing is executed through the adhesive (10) based on polyurethane. The vertical profile (4) can be reinforced with a steel bar (6) inside the aluminum profile (4a), increasing the inertia of the set formed by the aluminum profile (4a) of the vertical profile and the wood profile (4b) of the vertical profile, however it is not visible. Moreover, there are mechanical fittings (13) both in wood profiles (4b) and aluminum profiles (4a) to ensure good alignment between them.

In a preferred embodiment, the closing system of the present invention is multipoint and can be applied on the fixed rim (1), on at least one leaf (2) and integrated in the vertical profile (3) or in the handle (4), having in each one of these cases its location in the points (7), (8) and (9), respectively, as shown in FIG. 1.

The fixing technique of the wood is differentiated because it combines glue with screws and fittings.
