Abstract

A frame structure for doors and windows, for furniture or for lightings, having a surface on a same plane of a wall, for receiving at least one fixed or movable closure panel (60) , adapted to be incorporated in a wall (50 and 51) formed by boards (52) or in a brick-wall. The frame defines an aperture with which the closure panel (60) engages having at least one side on a same plane of the wall. The frame is made starting from a main section (1) having tubular cross section having one or more chambers, said main section having a first face at the same side of said aperture and a second face opposite to said aperture, two side faces substantially parallel to said wall, from at least one of said side faces a support wing protruding at right angles. This structure comprises, furthermore, a complementary section (4) suitable for completing to cover the thickness of said wall at said aperture. Furthermore, the frame can provide a section, adapted to be incorporated in a ground, in a ceiling or in a board-wall or in a brick-wall, having a housing for a fixed closure panel, for example for a fixed glass wall, adapted to clamping an edge of the closure panel, and at least one support wing protruding at right angles from a face of the main section oriented towards the closure wing, on an extension of the housing.

Description

Field of the invention

The present invention relates to the field of doors or windows, furniture and lightings having a surface on a same plane of a wall. In particular, the present invention relates to a combination of a frame, a panel and a wall according to the preamble of claim 1.

Descripion of the technical problem

Among the structures of frames for doors or windows having a surface on a same plane of a wall, frames are known defining an aperture for a door in a wall, wherein the frame is embedded within the wall same. Normally, such frames have uprights and crosspieces assembled separately before being mounted in the wall, obtaining a high quality and geometric precision when matching with the leaf panels. The installation of the above described frames provides the step of arranging the frame, previously assembled, within the wall at the aperture, fixing the frame in the wall and then stuccoing and finishing the side slits between frame and wall.
In particular, an Italian utility model, application N° VI2001U000007 , describes a frame for doors or windows with a concealed hinge having a surface on a same plane of a wall with one or two pull leaves, having uprights and crosspieces formed with a same profiled element. This profiled element has a box-like substantially rectangular cross section having a substantially triangular protrusion consisting of a first edge perpendicular to a side of the leaf, and a second edge oblique with respect to said first edge, said second oblique edge remaining embedded in the wall.
Such profiled element has the drawback that said oblique edge obstructs the arrangement of a board-wall, for example of plasterboard, thus requiring further work for cutting at an angle the end of the board to match the oblique edge of the profiled element, in such a way that a significant additional working and installation time results, with subsequent higher costs for manual work.
Furthermore, an Italian utility model, application N° BO97U000098 , describes a frame structure for doors or windows with concealed hinges and frame having a surface on a same plane of a wall with one or two pull leaves, wherein this frame is obtained with a first extruded profile with shoulders for a second complementary profile suitable for completing to cover the remaining part of the thickness of the wall, at the aperture of the wall. Even in this case the profile that forms the above described frame structure is shaped with concealed edges with oblique face adapted to be overlapped by plaster close to the aperture.
Therefore, also in this case, the known frame structure has the drawback that the concealed edge having oblique faces blocks the arrangement of a board-wall, causing the technical problem of cutting the boards at the aperture of the wall.
Similarly, Italian utility model N° BO97U000097 describes a combination of a frame structure, a closure panel and a wall according to the preamble of claim 1, comprising a frame structure for doors or windows with concealed hinges and frame having a surface on a same plane of a wall with one or two push leaves, comprising a first extruded profile with a shoulder associated to a second complementary profile suitable for completing to cover the remaining part of the thickness of the wall, at the aperture of the wall. Even in this case the above described first and second profile has an edge with an oblique face, having the same drawbacks as already described.

Summary of the invention

It is then a feature of the present invention to provide a frame structure for doors or windows for receiving at least one closure panel with at least one face having a surface on a same plane of a board or a wall, wherein said frame is operatively incorporated in said board or wall, where in case of boards the shape of the frame does not require to cut the boards.
Another feature of the present invention is to provide a frame structure for doors or windows adapted to fill modularly the thickness of the wall at the aperture in the wall.
A further feature of the present invention is to provide a frame structure for doors or windows of modular type, implemented at a desired thickness of the wall, which allows obtaining a high finishing quality, and with very low Installation time and cost.
It is still a feature of the invention to provide a frame structure for closure wings having a surface on a same plane of a wall, adapted to be used to form a built-in wardrobe or to close a space.
Another feature of tie invention is to provide a frame structure for a closure panel having a surface on a same plane of a fixed wall suitable to form a lighting that has a surface on a same plane of the wall, or of a board or a glass.
Another feature of the invention is to provide a frame, structure having a surface on a same plane of a wall adapted to receive an edge of a sheet or a glass completely concealed under a ground or ceiling surface.
Another feature of the invention is to provide a frame structure for a closure panel having a surface on a same plane of a wall forming an upper crosspiece without shoulder for doors having a central pivot.

Description of preferred exemplary embodiments

In the following description an example will be illustrated of a frame structure for doors or windows for receiving at least one closure wing, said frame being adapted to be incorporated in a board-wall or in a brick-wall, said frame defining an aperture where said closure panel engages, said closure panel having at least one side having a surface on a same plane of said wall.
The frame is obtained starting from a main section 1, 2 or 3, for example an extruded profile of aluminium, with one or more chambers, as described respectively in figures 1, 2, having a first face 31 from the side of the above described aperture and a second opposite face 30, two side faces 15 and 16 substantially parallel to the above described wall, from at least one of said side faces 15 and 16 a support wing 17 protruding at right angles that ends with a protrusion 18, suitable to form an edge about said aperture.
In the examples shown the profiles 1 and 2 (figure 1 and 2) have two support wings 17, which can also have different length from each other.
The above described main section 1, 2 or 3 comprises a inner guide groove 20, adapted to house a connecting element, for two adjacent portions of the above described section 1, 2 or 3, for example an upright and a cross member. Instead of a single connecting element two connecting elements can be provided.
Furthermore, main sections 1, 2 or 3 comprise a groove 25 arranged according to various positions, depending on the case, adapted to house a seal rubber not shown for tightness purposes when the above described closure panel is in the closed position. Groove 25 is obtained at first face 31, where it contacts an abutment surface 14, see figure 1, or on said abutment surface 14, see figure 2 .
In particular, figures 1 and 2 show two examples of main section 1 and 2 for making the uprights of a frame obtained according to the invention, respectively for at least one push-type closure panel 60, shown in figures 4 and 5, or for at least one closure with pull-type leaf 61, shown in figures 10 and 11. The above described first face 31 has a thicker portion 32, having a width substantially equal to the thickness of the above described closure wing, consisting of an inner wall 22 and an external wall 23, with interposition of a chamber 24. Alternatively, the chamber 24 can be absent, and the thicker portion 32 is solid. In the example described in figure 1, the main section 1 comprises a main chamber 10 and an adjacent chamber 11, whereas in the example 2 of figure 2 the main section 2 comprises a chamber 12 having a substantially rectangular cross section to support abutment surface 14.
Figure 3 shows a complementary extruded section 4 associable to the above described main section 1 and 2 described in figures 1 and 2, suitable for completing to cover the thickness of said wall at the aperture (for example in figure 5-9 and 11-15). This complementary section 4 has a reference face 41 adapted to operatively contact one of said side faces 1.5 of said main section 1 or 2, and an outer face 40 adapted to remain visible in the aperture defined by the frame on said wall.
On complementary section 4, furthermore, a complementary wing 45 can be provided, having a shape equal to wing 17 of main sections 1, 2 and 3 of figures 1, 2. The complementary wing 45 extends from said outer face 40 at the opposite ends with respect to said reference face 41. Furthermore, an engagement portion 42 is provided adapted to couple with said wing 17 of said main section 1 or 2 or to said complementary wing 45 of another complementary section 4. In particular, the above described engagement portion 42 is conformed in order to reproduce in negative the shape of the wing 17 of a main section 1 or 2, this engagement portion 42 being adapted to couple to wing 17 of a section 1 or 2 as above described or to a wing 45 of a next complementary section 4 mounted. In the example described, the outer face 40 and the reference face 41 are arranged substantially at an L configuration. The above described section 4 can have then a notch 44 in an intermediate position of the above described reference surface 41, adapted to assist cutting an exceeding portion, if required. The complementary section 4 of the example of figure 3 comprises a first support portion 47 parallel to the wall 50, shown in figures 4, 5 and 10, 11, which extends opposite to the outer face 40. From the first support portion 47 wing 45 protrudes at right angles. Furthermore, a second support portion 48 can be provided, parallel to said first support portion 47 and distant from said reference face 41 of the same length as the width of the wing 17 of a main section 1 or 2. Finality, the complementary section 4 has a complementary protrusion 55, equal to the protrusion 49 and the protrusion 18 of the main section opposite to the outer face 40 and at a distance from the second support portion 48 equal to the width of the wing 17 of the main section 1 or 2 or the wing 45 of section 4 same. This way, by eliminating the part exceeding protrusion 55, opposite to reference face 41, a wing 46 remains, substantially equal to wing 45. The inner surface opposite to the outer face 40 is knurled, as also the surface of the above described first and/or second portion of reference is knurled, and oriented outwards with respect to reference face 41.
Figure 4 shows a cross sectional view of an embodiment of a frame for doors or windows for receiving at least one push-type closure panel 60 having a surface on a same plane of a wall, mounted on a wall 50 having a thickness equal to the total width of a main section 1 and of a complementary section 4 associated. Obviously, alternatively, the invention can be fixed to a wall brick-wall 51. In figures 8 and 9, on the right side, a wall is shown obtained from boards 52, for example of plasterboard, without showing the relative support structure. Instead, on the left side a brick-wall 51 is shown,

Similarly, figure 9 shows a cross sectional view of an embodiment of a frame for doors or windows for receiving at least one closure panel having a surface on a same plane of a wall for a pull-type door 61, for a board-wall 50 of thickness equal to the width total of a main section 2 and of an associated complementary section 4. Obviously, like in figure 4, alternatively, the invention can be fixed to a brick-wall 51 (shown at the left).
Figures from 10 to 13, show alternative embodiments of assembling a main section 2 for a closure with pull-type leaf associated respectively to a complementary section 4, a partial complementary section 4', a complementary section 4 with a partial complementary section 4', two complementary profiles 4 in series, depending the thickness of the wall.
The examples of closure panels and walls are not limitative, being various other solutions possible according to the shape and the arrangements of the walls.
Figure 14 shows an alternative exemplary embodiment of a main section 3, as already shown in figure 16, but with two support wings 17 at opposite sides. Such a section 3 can be used for the frame of a door for access to a recess, for example a built-in wardrobe as shown in figure 27. More in the detail the section 3 has both side faces knurled and wings 17 protrude from such faces. The first face 31 from the side of the aperture comprises an enlarged portion 110 with a bevelled portion 111 to assist centring screws for fastening a hinge. The inner sides can comprise respective channels 112 for assembling the head of more profiles in turn.
Figure 15 shows possible assembling configurations of such a section 3 for a board-wall 52. Section 3 is mounted with a complementary section 4 in case of a wall of width higher than section 3. In case of a board-wall, section 3 can be mounted through a bracket 120.
