Description

BACKGROUND OF THE INVENTION

The present invention relates to a section member system for window and door frame in general, with thermal insulation means.
As is known, for making window and door frames in general, starting from conventional aluminium section members, a very felt problem is that of reducing the heat losses toward the outside environment.
This problem is partially solved by using the so-called double glasses which extend on the greater portion of the surface of the window or door frame and have a good thermal insulation coefficient.
A problem, however, which must be still solved in a satisfactory way is that of the thermal conduction, between the inside and outside environment, at the metal portions of the window frame, consisting of section members, which provide a thermal bridge because of the good heat conductivity of the used metal material, that is aluminium.
In order to solve this problem there have been already introduced on the market aluminium window and door frame section members, including the so-called thermal cutting characteristic, that is an interruption of the metal material of the section member between the inside and outside thereof.
Presently adopted approaches, however, are not able of satisfactorily solving this problem since they, in addition to an interruption of the metal surface of the section member, represent a mechanical weakening element in the obtained window or door frame, with the obvious drawbacks deriving thereform.
Other prior art section members of the above illustrated type have a good mechanical resistance but, in order to achieve it, the section members are provided with points thereat there is metal continuity between the inner surface and outer surface of the section member itself, with a consequent great reduction of the thermal insulation characteristics.

SUMMARY OF THE INVENTION

Accordingly, the task of the present invention is to overcome the above mentioned drawbacks, by providing a new section member system for making window and door frames in general, having thermal insulation means, that is means adapted to provide an efficient thermal cut, absolutely preventing a metal continuity between the outer and inner surface of the section member, while preserving a satisfactory mechanical strength of the section members and window and door frames made thereby.
Within the scope of the above mentioned task, a main object of the present invention is to provide a section member system which can be quickly and easily assembled without the use of skilled operators and which, moreover, is competitive from a mere economic standpoint.
According to one aspect of the present invention, the above mentioned task and objects, as well as yet other objects, which will become more apparent hereinafter, are achieved by a section member system for making window and door frames in general, with thermal insulation means, according to the invention, characterized in that said section member system comprises fixed frame section members and movable frame section members, having an inner body defining the inwardly facing surface and an outer body defining the outwardly facing surface, and intercoupled by thermally insulating means, consisting of coupling baffles, engaging in guide seats longitudinally extending on the opposite faces of said outer body and said inner body of said section members respectively.

With reference to the Figures of the accompanying drawings, the section member system for making window and door frames in general, including thermal insulation means, according to the invention, is characterized in that it comprises fixed frame section members and movable frame section members, which consist of an inner body, defining the inwardly facing surface, indicated generally at the reference number 1, and an outer body, defining the outwardly facing surface, indicated generally at the reference number 2.
The inner and outer bodies are intercoupled by thermally insulating means, consisting of coupling baffles 3, each whereof has a flat body 4 ending, at the edges thereof, with extended portions 5 provided for engaging in corresponding seats 6 formed on the surfaces of the opposite faces of said inner and outer bodies.
Advantageously, the outer and inner bodies are intercoupled by means of a pair of baffles 3, which are arranged with an adjoining parallel relationship.
Figure 1 shows a fixed frame section member 10, having a box-like inner body 1 provided with a side seat 11; the outer body 2 is provided with a top leg 13 having a seat 14 adapted to receive a corresponding gasket member.
Figure 2 illustrates a section member 21 the inner body 1 of which has a bottom leg 22, the outer body 2 having a shape analogous to that of the section member 10.
Figure 3 shows a section member, overally indicated at 23, the outer body 2 of which is provided with a box-like portion indicated at 24 having an outer leg 25, the inner body 1 having a substantially flat configuration and being provided with a ridge 26 at its end region.
Figure 4 shows a fixed frame section member 28, having an inner body 1 provided with a bottom edge 29, which is opposite to a bottom leg 30 defined by the outer body 2 also provided with a top leg 31.
Figure 5 shows a section member 33 of like shape, with the difference that the inner body 1 has no leg or edge 29.
Figure 6 shows a movable frame section member for making window frames, indicated overally at the reference number 40, the inner body 1 of which is provided with projecting lugs 41 and the outer body 2 of which is provided with a pair of opposite legs 42 and 43; moreover, one of the baffles 3 is provided with a side lug 44.
The section member 45 shown in Figure 7 is also provided for making a movable frame for windows and is provided with an inner body 1 having a bottom leg 46, its outer body being provided with a single leg 47.
The window movable frame 48 shown in Figure 8 is conceptually analogous to that shown in figure 6, with the difference that it is provided with a greater size inner body and a box-like portion 49 on the outer body 2.
Figure 9 shows a door movable frame section member, indicated at 50, having an inner body 1, with a bottom ridge 51 and an outer body 2 provided with a double leg 52.
The section member 53, which can be used for making door frames shown in Figure 10, has an inner body 1 with a leg 54, whilst the outer body 2 thereof is provided with a leg 55 and a step ridge 56.
