Abstract
The present invention relates to aluminium and wood combined window and door systems, wherein the wood sections are made of low-cost timber, the exposed surfaces of which are coated with a veneer of finer wood.
Description
Improvements to windows and doors, in particular aluminium and wood composite window and door systems .
Description of the prior art
Until recently, the timber part of aluminium and wood (alu- wood) composite window and door systems was made entirely of a single desired type of wood, either solid or laminated (i.e. made with two or three laminates glued together) . Only in the case of laminated profiles, in fact, some manufacturers, ■ to cut costs, assemble laminates of different types of wood, with the exposed layer of a finer wood and the underlying layers made of less costly timber.
Description of the invention
This invention relates to alu-wood composite windows and doors, wherein the wood parts are manufactured using low-cost wood on which a very thin coating of finer wood, commercially known as a "veneer", is applied by glueing; this coating technique is known as "veneering" and is already widely used in the furniture industry and for manufacturing internal doors, i.e. all items not directly exposed to the atmospheric agents.
Veneering has never been used for external window and door systems because the atmospheric agents, water, condensate moisture or humidity, can easily warp and damage the veneer. The aim of the present invention is to manufacture - with the above mentioned technique - timber sections for windows and doors, using finer woods at a low cost.
The invention, in fact, primarily relates to alu-wood composite windows and doors, wherein the external cladding is made of aluminium, while the internal part is made of timber sections. The latter, facing internally, behave in the same way as an internal door or item of furniture.
However, the external aluminium cladding is constantly exposed to the atmospheric agents and there can be infiltrations of water from the sill, if not suitably silicone-sealed, and rising damp, which can produce condensate moisture, especially if the sill is made of marble, granite or the like. Consequently, both the bottom horizontal member of the casement, directly above the window sill, and the lower ends of the vertical members, even though located internally, may be concerned, over time, by the warping of the veneer finish, because they are in contact with the stone sill. To prevent this from occurring, in a preferred embodiment, the wood section of the bottom horizontal member of the casement is made of solid or laminated wood and is joined to the upright members of the casement through a horizontal butt
joint, with the members docked at a 90° angle, and not the more commonly used vertical butt joint.
This assures that the veneered uprights of the casement do not come into direct contact with the stone sill and, therefore, do not absorb any water, damp, condensate moisture, etc., which, over the years, might cause the warping of and damage to the veneer.
Description of the drawings
The present invention will now be described with reference to the attached drawings:
Figure 1 shows an axonometric projection of the window/door according to the present invention.
Figure 2 shows an axonometric projection of the a conventional window/door.
Description o± the preferred embodiment
The preferred embodiment comprises the bottom horizontal member (1) of the window/door unit made of solid or laminated wood, or other material, such as aluminium, PVC, etc., joined to the uprights (2) , which are made of low-cost timber coated with a thin layer, or veneer, (7) of finer wood (3).
Figure 1 shows how the solid wood horizontal member (1) is joined to the veneered uprights (2) through a horizontal 90° butt joint (4) .
The external cladding of the window/door, i.e. -the part exposed to the atmospheric agents, is made of aluminium sections (5) .
The horizontal butt joint of the timber sections prevents the damp from the sill rising upward and damaging the upper part of the window/door unit, practically reducing to zero the possibility of warping or damaging the veneer of the uprights (2).
The same technique may obviously be used for alu-wood combined window/door systems, wherein the system features an aluminium core. in another embodiment of the invention, the veneer may also be made of paper printed to look like wood and called "laminitano".
In order to prevent even the remotest possibility of condensate moisture forming, a silicone sealant is used between the glazing and the wood sections.
As mentioned above, besides the advantage of having a window/door system made of wood and aluminium combined, which is pleasant to look at and particularly resistant to damp, another advantage consists, in the fact that such windows and doors are much less expensive than the standard composite windows and doors .
Although the forgoing invention has been described in some detail by way of illustration and example for purposes of clarity of understanding, it will be readily apparent to those of ordinary skill in the art in light of the teachings of this invention that certain changes and modifications may be made thereto without departing from the spirit or scope of the appended claims .
