Description

BACKGROUND OF THE INVENTION

The present invention relates to a thermal-cut section member assembly, for making slidable wing window and door frames.
As is known, in making slidable wing window and door frames, there are encountered great difficulties for obtaining the so-called "thermal cut" that is the interruption of the metal conducting bridges between the inner surface and outer surface of the section member forming the frame.
Actually, in prior art solutions, the thermal cut baffles are so designed as to remarkably reduce the mechanical strength characteristics of the section member.
Another problem affecting the slidable wing window and door frames, is that the guide rails thereon the wings of the frame slide, are subjected to a great wear, and it is not possible to replace the sliding tracks, thereby, in the time, the wings will encounter a great friction against their proper sliding.
Another drawback is that the slidable wing window and door frames have a poor application flexibility, since they do not afford the possibility of easily applying fitting to the window or door frames

SUMMARY OF THE INVENTION

Accordingly, the aim of the present invention is to overcome the above mentioned drawbacks, by providing a thermal-cut section member assembly, specifically designed for slidable wing window and door frames, which is adapted to provide both the fixed frame and the wings with a very high mechanical strength.
Within the scope of the above mentioned aim, a main object of the present invention is to provide such a section member assembly which allows to solve the problem of the wear of the guiding tracks of the slidable wings, so as to provide a very efficient frame.
Another object of the present invention is to provide such a section member assembly the section members of which can be easily made and assembled and which can be easily made starting from commercially available elements and materials and which, moreover, is very competitive from a mere economic standpoint.
According to one aspect of the present invention, the above mentioned aim and objects, as well as yet other objects, which will become more apparent hereinafter, are achieved by a thermal-cut section member assembly, for making slidable wing window and door frames, characterized in that said assembly comprises fixed frame section members, including a bottom rail and a top rail, connected by shoulder section members and having a central body adjoining, on its two sides, side bodies connected to said central body by means of spacer rods, made of a thermally insulating material, there being moreover provided sliding wing section member provided with box-like regions for housing therein connecting brackets, to the wing section members forming the central uprights there being coupled finishing section members, connected through the interposition of a latching section member made of a thermally insulating material.
Further characteristics and advantages of the present invention will become more apparent hereinafter from the following detailed disclosure of a thermal-cut section member assembly, for making sliding wing window and door frames, which is illustrated, by way of an indicative, but not limitative example,in the figures of the accompanying drawings, where:

DESCRIPTION OF THE PREFERRED

EMBODIMENT

With specific reference to the number references of the above mentioned figures, and, more specifically, to figures 1 and 2, fixed frame section members are herein illustrated, which comprise bottom rails, respectively indicated at the reference numbers 1 and 2, which are provided with a central body 3 and 3A which is connected to an innerside body 4 and 4Aand to an outer side body 5, by means of rods 6 engaged in corresponding seats and made of a thermally insulating material, of the polyamide type.
Moreover, at the bottom side, there are provided latching seats, indicated at the reference numbers 7 and 8, for the connection to the fixed structure.
The difference between the section member 1 and the section member 2 is that the section member 1 is provided, at the central body 3 and inner side body 4,with inter-exchangeable section members 9, forming the guide rail for the sliding wings and which can be replaced as they are worn out.
This is an important feature of the present invention, since it allows the window or door frames to be always held in perfect operation conditions, owing to the possibility of compensating, in a very simple manner, the wear of the parts subjected to a continuous sliding movement.
Figure 3 illustrates a fixed frame top rail section member, indicated at the reference number 10, which is provided with a central body 11, to which there are connected, by means of spacer rods, also indicated at the reference number 6, an outer side body 12 and an inner side body 13.
On the side bodies there are provided lugs 14 which, in cooperation with lugs 15 of the central body, will provide affixing regions for the connection to the fixed structure.
Advantageously, the elements are provided with box-like regions, with suitable housing seats in order to allow, by means of fixing screw, the connection with the shoulder section members, indicated at 20, which are provided with an inner box-like elongated body 21, connected to an outer body 22, through the rods 6.
On a face of the shoulder section members 20 there are provided seats 23, for coupling the spacer elements and position adjusting elements to the fixed structure, whereas on the ot her side there are provided fins 25, which extend perpendicularly with respect to the inner face and which operate as an abutment element for the sliding wings.
The sliding wings, as is shown in Figures 5 and 6, comprise a sliding wing section member 30 and a sliding wing section member 31 which are generally similar to one another, since they are provided with a box-like central body 32 including a seat 33 forengag- ing therein a glass-restraining section member, indicated at 34; from the central body there extending an inner leg 35 delimiting a box-like seat 36.
The outer leg, indicated at 37, is connected to the polyamide spacer rods 6 and, in the case of the section member 30, there are provided box-like seats 38 for engaging therein connecting brackets, whereas, with respect to the section member 31, the length of the spacer rods 6 is larger, and the outer leg 37 does not comprise any box-like seats.
The box-like seats allow to engage therein brackets from the two sides, for connecting and fixing the movable wing frame, which, in this manner, will have a great mechanical strength and will be properly connected.
At the central uprights of the movable wings, there is provided a finishing section member, indicated at the reference number40 and specifically shown in figure 7, which has a substantially L-shape, with a leg 40a arranged in engagement between the outer leg and inner leg of the section members 30 and 31 and being provided with a locking tooth member41.
The other leg or arm 40b, which is practically interposed between two movable wing frames, is provided with a hollow 42, in which there is engaged a locking or latching section member 45, made of a polyamide material and shown in figure 11, adapted to provide a thermal cut or interruption between the section member and movable wing and being moreover provided with an end portion 46 covering the free end portion of the arm 40b, where is performed the connection.
Near the attachment region of the covering leg 46, there is provided a seat 47, in which there is engaged a seal 48 which is practically compressed, in a closure condition, by the covering section member46 of the facing wing so as to provide a double sealing chamber, consisting of the two gaskets or seals 48 delimiting an air inner chamber 49, which will provide a perfect sealing with respect to the environment air.
Moreover, the front engagement between the end portion of the section member 46 and seals 48 will practically provide a resilient abutment or stop action, during the sliding movement, as the movable wings are coupled.
Figure 8 illustrates a fixed frame vertical section member, for providing a frame top portion, indicated generally at the reference number 50, which section member must be used as to a sliding wing window frame one must connect a fixed frame top or, possibly, a swinging openable frame top.
This section member 50 is provided with a box-like body 51 comprising engagement seats 52 for the connection to the fixed structure and, on the other side thereof, including an inner abutment leg 53, for the abutment against the swinging wing or against a fixed glass plate of the frame top.
Moreover, to the body 51 there is connected an inner body, indicated at 55, which is in turn coupled to the spacer rods.
Figure 9 illustrates a fixed frame horizontal section member for making a frame top, said section member being indicated at the reference number 60 and including a sloping central body 61, provided with an inner abutment leg 62 and coupling seats 63 on the other face thereof, allowing to perform a connection, as is shown in figure 17, with the top guide rail by means of fixing screws and by a covering section member 66 acting as a closure on the end faces.
Figure 17 specifically shows the provision of guide pads 70, made of a rigid plastic material, arranged on the sliding wing section members, and suitable to operate as guide elements against the projections 17 formed on the section member 10 which in turn practically operate as a holding and containment element for the sliding wing frame during the translation movement of the sliding wing.
Moreover, as is shown in figure 13, there is provided a closure lock, of the "raise and slide" type, indicated at the reference number 80, provided with an operating handle 81, including a cam engaging with locking means 84 connected to the shoulder section member 20 which, as already disclosed, is associated with the fixed structure by means of adjusting spacer elements.
From the above disclosure it should be apparent that the invention fully achieves the intended aim and objects.
In particular, the fact is to be pointed out that a section member assembly has been provided which allows to make sliding wing window and door frames which are very satisfactory from the operating standpoint, since it will provide a good thermal cut, without reducing the mechanical strength of the frame.
The invention as disclosed is susceptible to several variations and modifications, all of which will come within the scope of the inventive idea.
Moreover, all of the details can be replaced by other technically equivalent elements.
In practicing the invention, the used material, as well as the contingent size and shapes, can be any, according to requirements.
