Description

Field of application

The present invention refers to a door or window with fixed wing for outdoor settings, such as in particular a window or a French window for closing a wall opening, according to the preamble of the independent claim.
The present door or window is in general inserted in the industrial field of production of doors and windows, in particular but not exclusively of the type provided with a wood frame externally covered with aluminum sections.
The door or window object of the present invention can be associated with the internal walling of the building with different finishes, such as by means of plaster holder sections, plasterboard panels, or counter-frameworks made of wood and with installations which can for example be flush with the wall, or at the center of the walling or with installation on support structure of the type with metallic frameworks commonly indicated as SFS frameworks, acronym of "Steel Framing System" with which the frameworks with Metsec^® trademark are commercially known.
The door or window object of the present invention can be placed side-by-side other fixed wings or even movable wings with different opening solutions and is therefore of the type generically employable for obstructing, in a fixed manner, an opening made in a load-bearing structure of a building, being inserted as stated in the industrial field for producing doors and windows.

State of the art

Doors and windows have been known for some time that are of the type employable for closing openings made on load-bearing structures of buildings, e.g. constituted by a window or by a French window, provided with a fixed framework and with a wing rigidly and mechanically connected to the fixed framework.
More in detail, the present door or window with fixed wing is generically composed of a framework fixed to the walling, or more generally to the load-bearing structure of a building, and a panel, usually constituted by multilayer glass, directly mounted on the framework and fixed thereto by means of anchorage means, for example constituted by a frame.
The fixed framework consists of two first vertical uprights and two first horizontal crosspieces rigidly fixed to the vertical uprights at the ends in order to form a substantially quadrangular shape. The fixed framework is intended to be fixed to the load-bearing structure, whether this is a metallic structure or a walling, and more precisely is intended to be fixed to the internal faces of the walls which delimit the opening with which the door or window is associated.
Also known from the patent EP 0965718 is a door or window in which the anchorage means comprise a first element fixed to the fixed framework and provided with a plurality of externally-projecting teeth, and a second element slidably associated with a frame of the wing and provided with a second plurality of teeth engageable after a top to bottom movement of the first element in order to retain the wing on the framework.
Such door or window solution with fixed wing has in practice demonstrated that is excessively complex, both to make and install.
Also known, for example from patent EP 1353816 , is a door or window which provides for fixing the glass panel to the framework by means of anchorage means constituted by a glue layer.
Also such door or window solution with fixed wing has in practice demonstrated that it is not satisfactory, since in case of maintenance of the wing, i.e. for example of substitution of the glass panel, it is necessary to separate the wing from the framework with operations that are difficult due to the presence of the glue layer.
US3296763A relates to means for securing interchangeable panels such as glass and screen panels in the framed openings provided therefore in windows and doors or like facilities normally found in building apertures.

Presentation of the invention

In this situation, the problem underlying the present invention is therefore that of overcoming the drawbacks manifested by the solutions of known type, by providing a door or window with fixed wing for outdoor settings which allows rigidly associating the wing to the framework in a facilitated and quick manner.
A further object of the present invention is that of providing a door or window with fixed wing for outdoor settings, which allows easily removing the fixed wing for each type of maintenance.
A further object of the present invention is that of providing a door or window with fixed wing for outdoor settings which is entirely safe and reliable in operation.

Detailed description of a preferred embodiment

With reference to the enclosed drawings, reference number 1 overall indicates the door or window with fixed wing for outdoor settings, object of the present invention.
Such door or window is operatively engageable for closing, in a fixed manner, an opening made in a load-bearing structure of a building, e.g. a wall structure. Such opening can for example be for a window, a door or a French window or other similar doors or windows.
Such opening is usually defined in the walling of a building between two lateral, substantially vertical walls, a substantially horizontal lower wall and a substantially horizontal upper wall.
Such opening can otherwise be defined between parts of the walling or load-bearing structure of the building and other doors or windows whether they are of the type with fixed wing or with movable wing.
Such opening will preferably have quadrangular shape, and more in detail rectangular or square shape.
The door or window with fixed wing for outdoor settings 1 comprises, in a per se conventional manner, a fixed wing 3 provided with a first support frame 30 and with at least one glass panel 40 (with one or more panes) perimetrically fixed to the aforesaid support frame 30, and a fixed framework 2, which supports the fixed wing 3, and comprises at least one second support frame 20.
The door or window for outdoor settings 1, object of the present invention, can be advantageously employed for making single or double fixed wings of windows or French windows or for similar doors or windows of the type for example with a fixed wing and a movable wing.
The door or window 1 also comprises anchorage means 6 for rigidly connecting the first support frame 30 of the fixed wing 3 and the second support frame 20 of the fixed framework 2.
More in detail, the first support frame 30 of the fixed wing 3 is provided with a first perimeter face 32, which is directed towards the interior of the support frame 30, and which mechanically carries the glass panel 40 associated therewith, and with a second perimeter face 33, which is directed towards the exterior of the support frame 30, i.e. towards the second support frame 20 of the fixed framework 2, and is provided with at least one shaped seat 100.
Advantageously, the first and the second perimeter face 32, 33 of the first frame 30 of the fixed wing 3 are extended between a first internal surface 34 and a first external surface 35 of the first frame 30, which are respectively directed towards the interior and exterior of a building when the door or window 1 is mounted on the load-bearing structure.
In turn, the second support frame 20 of the fixed framework 2 is provided with a third perimeter face 22, which is intended to be fixed to the load-bearing structure of a building at the opening, and with a fourth perimeter face 23, which is directed towards the fixed wing 3, and is opposite the first perimeter face 33 of the first frame 30 of the fixed wing 3, when this is fixed to the fixed framework 2.
More in detail, the fourth perimeter face 23 is directed towards the first support frame 30 of the fixed wing 3 and is susceptible of being anchored to the first perimeter face 33 of the first frame 30 of the fixed wing 3 by means of the abovementioned anchorage means 6.
In addition, the fourth perimeter face 23 comprises a sunken section 23A which is opposite the shaped seat 100, made in the second perimeter face 33 of the first support frame 30 of the fixed wing 3, and a raised section 23B.
Advantageously, the third and the fourth perimeter face 22, 23 of the second frame 20 of the fixed framework 2 are extended between a second internal surface 24 and a second external surface 25 of the second frame 20, which are respectively directed towards the interior and towards the exterior of a building when the door or window 1 is mounted on the load-bearing structure.
In accordance with the aforesaid configuration, the second perimeter face 33 of the first frame 30 of the fixed wing 3 and the fourth perimeter face 23 of the second frame 20 of the fixed framework 2 define two opposite perimeter faces 33, 23 delimiting a slit F.
Seal means 7 are then advantageously provided, mechanically associated with one of the two opposite perimeter faces 33, 23 of the first and of the second frame 30, 20 in order to seal the fixed wing 3 on the fixed framework 2.
In accordance with the idea underlying the present invention, the anchorage means 6 comprise a plurality of pawls 8, projecting from the at least one aforesaid shaped seat 100 of the first support frame 30 of the fixed wing 3 towards the second support frame 20 of the fixed framework 2 and a corresponding plurality of lever clips 9. The shaped seat 100 preferably has perimeter extension, as can be appreciated for example in figure 5, so as to use the frame of a movable wing which has such shaped seat in order to contain the normal opening and closing hardware and possibly also the hinges. Otherwise, shaped seats 100 can also be provided, each for receiving a corresponding pawl 8.
Each lever clip 9 comprises a head 9A pivoted to the sunken section 23A of the second support frame 20 of the fixed framework 2 in a position opposite a corresponding pawl 8 and an arm 9B projecting from the head 9A and manually actuatable to rotate around the head 9A.
More in detail the head 9A is provided with a retention seat 95 for the pawl 8, provided with an opening 91 susceptible of being transversely crossed by the pawl 8. Advantageously, the retention seat 95 is defined by means of a curved rib 90 which projects towards the first support frame 30 of the fixed wing 3.
The arm 9B is advantageously obtained in a single body with the head 9A and is manually actuatable to rotate around the head 9A between a retention position A of the fixed wing 3 (figure 2), in which advantageously the arm 9B is aligned with the perimeter extension of the second support frame 20 of the fixed framework 2, and in which the curved rib 90 retains in the retention seat 95 the pawl 8, and a release position B of the fixed wing 3 (figure 3), in which the arm 9B advantageously projects transversely to the plane of the second support frame 20 of the fixed framework 2, and in which the curved rib 90 releases the passage of the pawl 8 to exit from the retention seat 95 through the opening 91.
The lever clips 9 can rotate with the arm 9B thereof within the slit F defined between the two frames 20 and 30 of the fixed framework 2 and of the fixed wing 3.
The fixed wing 2 is inserted from the indoor setting into the space defined by the fixed framework 3 up to abutting against an abutment 60 directed towards the indoor setting.
The fixed wing 2 is then extractible from the fixed framework 2, to which it is rigidly anchored by means of the anchorage means 6, by manually moving the lever clips 9 from the retention position A to the release position B. The abutment is for example attained through the abutment of the pawls 8 against a step 60 made on the fourth perimeter face 23 of the second frame 20 of the fixed framework 2.
More clearly, in accordance with the example illustrated in the enclosed figures, when the arms 9B of all the lever clips 9 are horizontally oriented towards the indoor setting, it is possible to extract the pawls 8 integral with the first frame 30 of the fixed wing 3 from the retention seats 95 of the same lever clips 9. When instead the arms 9B of the lever clips 9 are oriented along the extension of the frames 20, 30 then the pawls 8 interfere with the ribs 90 of the lever clips 9 and the fixed wing 3 is retained integral with the fixed framework 2.
Advantageously, for such purpose, the openings 91 of the retention seats 95 of the lever clips 9 are substantially oriented towards the extension of the respective arms 9B.
Preferably, the openings 91 of at least two contiguous lever clips 9 are directed, when the latter are in retention position A, with orientation in opposite directions in order to avoid undesired clearances of the fixed wing 3 along a common direction of the openings 91. In figure 1, two arms 9B of the lever clips 9 are visible in a nearly final retention position and with the openings 91 as well as the relative arms 9B aligned with the openings 91, directed opposite.
Due to the present invention, the fixed wing 3 is integrally and securely retained on the fixed framework 2 but simultaneously can be easily removed for example for maintenance operations, by simply manually rotating the arms 9B of the various lever clips 9.
In accordance with the preferred embodiment of the present invention, the pawl 8 is fixed to the bottom of the shaped seat 100 of the first support frame 30 of the fixed wing 3 by means of at least one first screw 82. In addition, the pawl 8 in particular has cylindrical shape with the first screw 82 which is axially arranged within the tubular cylindrical body 8' of the pawl 8.
In turn, the lever clip 9 has substantially elongated plate form with the curved rib 90 that delimits the retention seat 95 provided at one end thereof.
Advantageously, the lever clip 9 is pivoted to the sunken section 23A of the second support frame 20 of the fixed framework 2 by means of at least one second screw 92, which is advantageously provided on the head 9A of the lever clip 9, on the bottom of the retention seat 95 and at the center of the curved rib 90.
As can be appreciated in figure 6, advantageously the first and the second screw 82, 92 are aligned with each other along the axis Y in figure 6.
In order to ensure a correct rigid retention of the fixed wing 3 on the fixed framework 2, the pawls 8 and the lever clips 9 of the corresponding pluralities are distributed along the sides of the perimeter of the first and of the second frame 20, 30 at a mutual distance D comprised between 25 and 55 cm and preferably of about 40 cm.
The abovementioned slit F is extended between an internal opening F1 and an external opening F2 respectively delimited between the first internal surfaces 34, 24 and the second external surfaces 35, 25 of the aforesaid first and second frame 30, 20.
The door or window 1 also comprises seal means 7, which are mechanically associated with one of the two perimeter faces 33, 23 of the two frames 30, 20 and are susceptible of sealing the fixed wing 3 on the fixed framework 2 when the fixed wing 3 is in closed position A.
The aforesaid seal means 7 for example comprise one or more gaskets which close the slit F between the indoor setting and the outdoor setting. For example, a first perimeter gasket 70 and a second perimeter gasket 71 are provided. The first perimeter gasket 70 is fixed to one of the two opposite perimeter faces 33, 23 of the two frames 30, 20 (and preferably to the first frame 30 of the fixed wing 3), and is susceptible of acting against an opposite first flat section 23A of the perimeter face 23 of the opposite frame 20, 30. The second perimeter gasket 71 is fixed to one of the two opposite perimeter faces 33, 23 of the first and of the second frame 30, 20, and is susceptible of acting against an opposite second flat section 33A of the perimeter face 33 of the opposite frame 20, 30, placed at an intermediate position between the internal opening F1 and the external opening F2 of the slit F.
The first perimeter gasket 70 is arranged at the enlarged section F" of the slit F towards the internal opening F1 and is susceptible of concealing from view, from the interior, the lever clips 9 when the latter are rotated in retention position A.
Advantageously, in accordance with a possible embodiment variant illustrated in figure 8B, each pawl 8 is extended along an axis extended starting from a section having a non-circular geometric shape, i.e. provided with at least one larger axis D and with at least one smaller axis d, in particular obtained with an elliptical profile. The pawl 8 in this manner defines a narrow size directed towards the interior of the door or window and a widened size directed along the extension of the shaped seat 100.
Each pawl 8, fixed in the shaped seat 100 of the fixed wing 3 for example by means of the first screw 82, is also further engaged in the same shaped seat 100 due to a counter-shaped portion 800, e.g. in the form of an annular plate, which prevents the axial rotation thereof.
In operation, the pawl 8 enters into the retention seat 95 of the head 9A of the lever clip 9 in a facilitated manner by crossing the opening 91 thereof, due to its orientation which brings it to pass with its narrow size and then it is fittingly engaged with friction in the same retention seat 95 once the lever clip 9 has been rotated in the retention position A. Advantageously, the arm 9B of the lever clip for its actuation in rotation can have a tapered shape towards the free end as shown in figure 9, and advantageously can also have an edge with at least one step 900 in order to be able to grip with a tool when the arm 9B is in retention position A within the slit F.
The shaped seat 100 can be obtained by advantageously using that normally provided in a movable wing, in such case provided at its interior not with anchorage means but rather with hinging means as well as the hardware necessary for closing the fixed wing 3 on the fixed framework 2.
Such shaped seat 100 of the second perimeter face 33 of the first frame 30 of the fixed wing 3 is arranged at the enlarged section F" of the slit F in order to make the arm 9B of the lever clips pass in a facilitated manner.
Advantageously, the seal means 7 comprise a third perimeter gasket 73, which is fixed to the fourth perimeter face 23 of the second frame 20 of the fixed framework 2 at the external opening F2 of the slit F.
In accordance with the preferred embodiment illustrated in the enclosed figures, the door or window 1 comprises a first protection framework 80, fixed to the first external surface 35 of the first frame 30 of the fixed wing 3 and a second protection framework 81 fixed to the second external surface 25 of the second frame 20 of the fixed framework 2.
The seal means 7 comprising a fourth gasket 74 interposed between the first and the second protection framework 80, 81. The aforesaid fourth gasket 74 is advantageously mounted in a groove made on the second protection framework 81 at a section on top of the first protection framework 80 and it is directed towards the interior of the building.
The first perimeter face 32 of the fixed wing 3 is provided with a perimeter seat 96 for containing the glass panel 40, and it is delimited by a second step 97 and by the first protection framework 80; the latter contributes to retaining the glass panel 40 sealed by means of gluing in said perimeter seat 96. The glass panel 40 can comprise one, two or three parallel glass panes separated by respective double glazing.
The door or window thus conceived therefore achieves the pre-established objects.
It is however clear that modifications can be made to the door or window for outdoor settings described up to now, without departing from the protective scope of the present invention as defined by the appended claims.
