LARGE SURFACE AND FULL-SEALED WINDOW

SEALED

The present invention generically refers to a large-surface sliding window (or window or door) with complete hermetic seal.

More specifically, the invention relates to a window or door of the type known in the building sector as a â € œlifting slidingâ € window, installed in correspondence with passage and / or ventilation spaces, such as windows, doors, facades and the like. obtained in the wall of buildings.

It is known that in the building sector windows are used for closing passageways and / or ventilation of buildings; furthermore, the reference market requires, for these types of doors and windows, ever higher thermal insulation capacities from atmospheric agents, both in summer and in winter.

Furthermore, according to the needs of the market, the doors and windows must help to isolate the environments or premises of the buildings also from an acoustic point of view, dispersing the noises coming from the outside that can disturb the normal work, recreational and / or rest activities of the people.

In addition to these prerogatives, the doors and windows must in any case necessarily have other physical properties, such as lightness, in order to be handled by the user without particular difficulties or impediments, as well as mechanical resistance, sturdiness and structural non-deformability under the action of atmospheric agents and the continuous cycles of opening and closing, in order to ensure perfect airtightness in closed conditions and to discourage or effectively counteract vandalism.

Furthermore, according to the recent and most sought-after trends in building architecture, the doors and windows must also satisfy purely aesthetic needs which, in order to limit as much as possible the presence of structural discontinuity points in the wall, provide for totally hiding the frames of the doors and windows inside the perimeter wall that delimits the passageway, so that, when the passageway is closed, only the front door at the interface between two contiguous environments remains visible, offering a particularly pleasant aesthetic impact and almost undetectable if it consists of a simple transparent glass plate.

However, in order to meet these needs, the known lift-and-slide doors, which have the load-bearing frame inserted in special niches inside the perimeter wall that delimits the passageway and which usually include one or more front doors, fixed to the load-bearing frame and sliding along a linear direction, generally horizontal, are, especially if large, remarkably heavy and expensive.

Furthermore, the applications in which sliding on a special rail or lower slot is foreseen have further drawbacks, such as the use and cost of the hardware necessary to make the guide or slot, the infiltration of water, humidity and / or impurities of various kinds inside the aforementioned guide or slot, the discontinuity of the flooring and the consequent imperfection of this technical solution, as well as the impossibility of obtaining a complete hermetic seal, not only laterally to the opening compartment , but also above and below, in order to guarantee a perfect closure on all sides of the window. The purpose of the present invention is therefore to obviate the aforementioned drawbacks of the prior art and, in particular, to provide a large-surface, fully hermetically sealed sliding window or door or window, which allows to create a large opening surface. dimensions, possibly without a frame and equipped only with an infill panel, for example a glass panel, or double-glazing or blind panel, and which is, at the same time, light and easy to handle, as well as cheaper than similar structures of a traditional type, with regard to production and / or maintenance costs.

Another purpose of the invention is to create a large surface sliding window or door that is aesthetically pleasing, as well as almost hermetically sealed on all four sides of the compartment concerned.

These and other purposes, which can be better evaluated in the course of the discussion, are achieved by a lifting or sliding window with a large surface and a complete hermetic seal according to the attached claim 1; other detailed technical characteristics of the window frame of the invention are contained in the related dependent claims.

Advantageously, the frame object of the invention considerably reduces, with respect to the known technique, the use of hardware, such as rails, covering elements, etc., as well as maintenance, replacement of mechanical parts and cleanliness, with the obvious operational and economic savings resulting.

Still advantageously, the frame object of the invention increases, compared to known types of windows, the structural continuity in correspondence with the passage and / or ventilation compartments in which it is installed, eliminating imperfections and / or dangers for users and guaranteeing levels of thermal insulation higher than those of the known type of lift and slide.

With reference to the aforementioned figures, the large-surface and completely hermetically sealed sliding window frame, which is the subject of the present invention, first of all comprises a structural profile or beam 1, mounted above and in correspondence with the compartment 7 to be closed, at least partially, with at least one wing 8 belonging to the window frame.

The beam 1 is C-shaped and suitable to support the motorization for the vertical movement (lifting) of the window frame, according to the invention. Furthermore, a series of slots 1.1 are provided on the vertical wall 6 of the C, variously distributed and suitably positioned on the wall 6 according to the length and weight of the window frame, which are placed diagonally and suitable for the sliding of the pins 2.1, equipped with relative bearings, which, in turn, are connected to a lifting profile or beam 2, L-shaped and equipped with a special guide 2.2 for the insertion of the dragging or horizontal sliding motor 3 (including elements 3.1, 3.2, 3.3, 3.4) of leaf 8 of the window frame according to the invention.

The pins 2.1 are inserted and slide inside the respective slots 1.1 during the lifting movement of the window, as will be described in detail later in the discussion, in order to ensure the hermetic seal of the window itself, thanks to the maintenance of the vertical axiality during the horizontal sliding movement (the X direction identified in detail in the attached figure 9) of the leaf 8 and during the vertical lifting movement (the Y direction identified in the attached figure 9) of the entire window frame.

The horizontal advancement of the door 8 takes place thanks to a sliding system comprising a bracket 3.2, C-shaped and placed in front of the beam 2, to which the sliding door 8 is fixed and inside which is placed a sliding block, which includes a U-shaped profile 3.1 and containing a pulley 3.4, fixed to the bracket 3.2 and to the profile 3.1 and mounted vertically, which receives the motion from the drive motor 3.

Also fixed to the bracket 3.2 are a series of rollers 3.3, mounted horizontally and contained inside the upper seat 1.2 of the C-shaped beam 1, in order to maintain correct horizontal alignment of the window frame; the rollers 3.3 are connected to the bracket 3.2 by means of a hub 3.5 of variable length, in such a way as to be able to adjust the horizontal alignment of the window according to the type, length and weight of the entire window.

According to the present invention, during the horizontal sliding (X direction) of the bracket 3.2 and, consequently, of the leaf 8 (which is fixed to the bracket 3.2), a vertical lifting (Y direction) of the locking block also takes place. sliding and, therefore, of the bracket 3.2, of the profile 3.1 and of the L-shaped beam 2, with respect to the C-shaped beam 1, which is fixed and integral with the installation wall of the window or door.

This lifting movement takes place thanks to the use of a worm screw (helical) 4.4, placed on the bottom 1.3 of the beam 1 and below the seat 2.2 of the beam 2, on which a series of 4.1 square nuts are arranged, a worm motor (helical) 4.3 and at least one wedge 4.2, formed by an upper wedge 4.2a, fixed on the lower surface 2.4 of the beam 2 (parallel to the bottom 1.3 of the beam 1), and by a lower wedge 4.2b, sliding on the worm 4.4; two wedges 4.2 allow the lifting of the L-shaped beam 2. According to preferred embodiments of the present invention, moreover, the drive motor 3, responsible for the horizontal sliding of the bracket 3.2 and of the leaf 8, can be powered by lines 5.1 low voltage electrical cables (typically 12 or 24 Volt, direct current), obtained on beam 2 and connected to a power supply box 5.2, on which the sliding brushes of the drive motor 3 slide during the movement of the entire block of scrolling.

The drive motor 3 is thus always energized, thus avoiding any drawbacks of using a rechargeable buffer battery, which supplies energy only when the leaf 8 slides horizontally X.

In practice, according to the present invention, the motor 4.3 (without rack), adapted to drive the nuts 4.1 on the worm screw 4.4, determines, during the sliding or horizontal dragging phase (X) of the leaf 8 (determined by the drive motor 3 powered by the electrical lines 5.1 and by the power supply box 5.2), a simultaneous gradual lifting of the leaf 8, as the relative nut 4.1, mounted on the worm screw 4.4, allows the sliding of the beam 2 on a plane inclined of the wedge 4.2, thus lifting the profile 3.1 and the bracket 3.2, with respect to the beam 1 (as shown in detail in the attached figures 23, 24, 25 and 26).

This allows to move the door 8 without having to provide a sliding track, placed on the floor, and still maintaining a considerable hermetic seal, since, during the sliding in the horizontal direction X and the simultaneous vertical lifting Y of the door 8, the pins 2.1 of the beam 2 move diagonally inside the respective inclined slots 1.1, obtained on the beam 1, so as to follow the movement of the door 8 and therefore reach a final closing and final locking position of the frame on the hermetic gaskets provided on the sides of the compartment 7 and / or on the leaf 8 (as shown in detail in the attached figures 21 and 22).

The particular arrangement of the slots 1.1, which are obtained diagonally on the beam 1, also allows to obtain the definitive locking of the window and its hermetic seal in correspondence with at least three sides of the compartment 7 even in conditions of leaf 8 of the semi window. -closed.

On the basis of the description just provided, it is therefore understood that the window frame according to the invention achieves the purposes and achieves the advantages mentioned above.

During the execution phase, changes may be made to the frame of the invention consisting, for example, in a number of front doors, dragging and sliding motors, nuts and wedges different from that used as a reference base for the previous description, this number being able to vary according to the surrounding conditions of the insertion of the window frame, the needs and / or constructive choices and, in particular, according to the overall length of the window frame, its type and weight.

It is also emphasized that the front door of the window frame of the invention will be able to identify a plurality of operating positions, being able to maintain the hermetic seal on the closed sides of the window even with the door partially open in correspondence with the passageway and / or ventilation in the wall of the building.

It is clear that numerous other variations can be made to the window frame in question, without departing from the principles of novelty inherent in the inventive idea expressed here, just as it is clear that, in the practical implementation of the invention, the the materials, the shapes and the dimensions of the illustrated details may be any according to the requirements, and replaced with other technically equivalent ones.

Where the construction features and techniques mentioned in the subsequent claims are followed by reference marks or numbers, these reference marks have been introduced with the sole aim of increasing the intelligibility of the claims themselves and, consequently, they have no effect. limiting on the interpretation of each element identified, purely by way of example, by these reference signs.
