Description

Description
Profile for sliding doors and windows, method for making the profile and door or window made with the profile
Technical Field
This invention relates to a profile for sliding doors and windows, the method for making the profile and the door or window that can be made with the profile.
Background Art
Sliding doors and windows are usually composed of:
- a fixed frame (the simplest and most common versions of which also include a fixed sash mounted on a first track);
- at least one mobile frame or sash that opens and closes by sliding horizontally relative to the fixed frame (and in a direction parallel to the fixed sash);
- a pair of carriages associated with the bottom horizontal member of the sash and resting on a second horizontal track (parallel with the first track that supports the fixed sash) and designed to enable the sash to slide in both directions;
- a drive element located on the sash and designed to actuate operating means used to disengage the sash from the fixed frame so that it can be slid open and to stop the sash in a closed positioned where it is locked to the fixed frame; - closing means acting at least between the vertical member of the sash and the vertical member of the fixed frame (which, in the closed configuration, abut against each other edge to edge).
Sliding doors/windows of this kind are among the most common and widely used on the market since they offer a high level of active security, need less space than swinging doors/windows and are suitable for buildings with large, glass-panelled surfaces.
In contrast with these undoubted advantages, sliding doors/windows offer a lower level of thermal insulation than other types of doors/windows (such as tilt and turn, for example). In most cases (as demonstrated by innumerable tests), the cause of the poor thermal seal lies in the fixed frame.
In particular, the poor seal is due to the top and the bottom horizontal member A of the fixed frame. These horizontal members are made up of a base profile PB from which emerge the above mentioned two tracks Bl and B2 which have shared surfaces in contact with both the inside zone ZI and the outside zone ZE of the structure where the door/window is installed: these shared areas can be identified in particular in the parallel pair of sliding tracks Bl and B2.
In fact the architecture used to permit sliding of the sash or sashes Al and A2, with "overlap" or overlay of the sashes themselves, leaves uncovered large parts of the surfaces corresponding to the tracks Bl and B2, thus allowing heat transfer between inside and outside (see Figures 1 and 2).
To overcome this drawback, "thermal break" systems are currently used. These are applied to extruded aluminium profiles and basically consist of bars G made of polyamide (a material with low thermal transmittance) which divide the profile of each horizontal member of the door/window lengthways along the middle.
Thermal energy or heat is transferred from one zone to another in three basic ways: conduction, convection and irradiation. The heat passes from the zone where the temperature is higher to the one where the temperature is lower. If the two zones are separated by a dividing structure, the amount of heat that passes through the structure is proportional to the difference in temperature.
In the case of a sliding door/window (as may be clearly observed in Figures 1 and 2), this thermal break system applied to the frame does not provide optimum performance because the metal surfaces of the horizontal members with faces common to both inside and outside are never completely separated and always allow a certain amount of heat transfer by inside-to-outside conduction and vice versa at the tracks despite the thermal break bars and the sealing strips on both sides of the profile of the mobile frames or sash which, when closed, are in contact with the tracks. Another particularly critical aspect of sliding doors/windows in terms of thermal efficiency relates to the central zone where the sashes Al and A2 overlap when closed (the vertical members of the sashes being obviously provided with sealing strips, as is well known).
As may be clearly inferred from Figure 1, the space between the two tracks, common to both inside and outside, is a potential site of thermal leakage: at present, this zone is protected by an element G which, in theory, acts as a "seal", although not very effective since it does not create a good thermal break along the profile.
To this must be added the fact that recent energy saving legislation will cause doors/windows of this type to be gradually phased out unless they can be improved in terms of thermal efficiency.
Disclosure of the Invention
This invention therefore has for an aim to overcome the above mentioned drawbacks by providing a profile for doors/windows having good thermal insulation properties while maintaining mechanical and aesthetic properties similar to those of traditional profiles.
Another aim of the invention is to provide a very simple method for making the above mentioned profile and involving limited additional costs. It is a further aim of this invention to obtain a sliding door/window using said profile and having good thermal insulation properties.
According to the invention, the above aim is achieved by a profile, in particular a profile for sliding doors/windows, comprising the technical characteristics set out in one or more of the appended claims. Also in accordance with the invention, the above aim is achieved by a method for making a profile for sliding doors/windows, comprising the technical characteristics set out in one or more of the appended claims.
Also in accordance with the invention, the above aim is achieved by a sliding door/window comprising the technical characteristics set out in one or more of the appended claims.

Detailed Description of the Preferred Embodiments of the Invention
With reference to the accompanying drawings, in particular Figures 3, 4 and 9, the profile according to the invention is used to make frames for sliding doors/windows 1 which, purely by way of non-limiting example, comprise (see Figure 9): a fixed frame 2 defined by two horizontal members 3 and 4 and two vertical members 5 and 6 and where the profile 7, defining a first bottom horizontal member 3, comprises two parallel sliding tracks 8 and 9 made on a bottom base element 10.
The door/window also comprises a first mobile frame or first sash 20 that opens and closes by sliding horizontally relative to the fixed frame 2 on a first track 8 and by means of a pair of carriages 21 and 22, and a second sash 23 that may also be slidable on the other track 9.
As illustrated in Figures 3 and 4, the profile 7 comprises:
- a cavity or seat 11, shown clearly in Figure 7, formed in the profile 7 through its full depth S (defined by the element 10 and the tracks 8, 9), extending transversally of the tracks 8 and 9 and adapted to stably accommodate
- a thermal insulation or thermal break block 12, a part of which is shaped to match the cavity or seat 11 and which also acts on at least one part of the tracks 8, 9; - thermal insulation means 13 acting longitudinally along the full length L of the bottom element 10 of the profile 7 and acting also on the tracks 8 and 9.
Similarly, the profile T, defining the second, top horizontal member 4 may comprise a cavity or seat 11' formed in the profile 7' through the latter's full depth
S and extending transversally of the tracks 8 and 9. The cavity or seat 11' (Figure 7) stably accommodates a thermal insulation or thermal break block 12', a part of which is shaped to match the cavity or seat 11' and which also acts on at least one part of the tracks 8, 9.
In this case, too, there are thermal insulation means 13' acting longitudinally along the full length L of the bottom element 10' of the profile T and acting also on the tracks 8 and 9.
For the sake of simplicity, the characteristics of the profiles 7 and T described hereinafter apply to both the profiles, defining the top and bottom horizontal members, and, without limiting the scope of the inventive concept, will not be "duplicated" in each case. Again with reference to Figures 3 and 4, the cavity or seat 11 and 11'
(shown clearly in Figure 7) is made substantially in the middle of the profile 7, T in such a way as to partly break the bottom base element 10 and 10' and at least partly break the tracks 8 and 9 and the thermal insulation means 13 and 13' (see also Figure 5). As shown in Figures 4 to 6, the thermal insulation means 13, 13' are located at least on the bottom base element 10, 10' and extend lengthways along the full length L of the profile 7, T.
Looking in more detail, the thermal insulation means 13 and 13' are located and act on both the tracks 8 and 9 of the profile 7, 7'. A part of each of the thermal insulation means 13 and 13' is in contact with the thermal break block 12 , 12' in such a way as to define a zone of uninterrupted thermal insulation on the profile 7, T according to a path which, viewed from above, forms an H-shaped configuration along the profile 7, 7' itself (see Figure
3). As clearly illustrated, again in Figures 4, 5 and 6, the profile 7, T comprises, in cross section, a base portion 10, 10' and two pairs of arms 14 and 15 protruding vertically, and transversal to the base portion 10, 10', each pair 14, 15, defining the body of the respective track 8, 9.
Each of the thermal insulation means 13, 13' is comprised of a pair of flat rods 13 a, 13b made of a thermally insulating material (for example, polyamide) for each track 8, 9.
The two rods in each pair 13a and 13b are parallel to each other and positioned, respectively, the former 13a at the base of one of the pairs of arms 14 and 15, and the latter 13b under the first rod 13a and at the bottom zone of the base portion 10, 10'.
Each rod 13a, 13b is bilaterally associated with the profile 7, 7' through respective coupling grooves 16, 17.
The pair of rods 13a, 13b is partly broken in such a way as to form an end part of the cavity or seat 11, 11' in the middle of the profile 7, 7', and in stable contact with the thermal break block 12, 12' when inserted.
To improve thermal efficiency, another thermal insulation or thermal break element 18 (see broken line in Figure 4) may be provided, positioned in and acting on an area half way along the profile 7, T and which, obviously, has a break in it where the cavity or seat 11, 11' (see Figure 7) is made. To further improve the thermal efficiency of the profile 7, 7', the thermal insulation means 13, 13' may also include the tracks 8, 9.
Thus, (as illustrated, again in Figures 4 and 5) the pairs of track arms 14 and
15 of the profile 7, T may be provided with respective internal supports 8i, 9i, each in the shape of an upturned U fitted between each pair of arms 14 and 15, and having a rounded head 8t, 9t (forming the area which supports the carriages 21 and 22 and on which the latter slide).
In this specific case, each track 8 and 9 made in this way is a single block of thermal insulating material.
In another embodiment, illustrated in Figure 6, each pair of arms 14 and 15 constituting the tracks 8, 9 of the profile 7, T may comprise a support 8i, 9i in the shape of an upturned U fitted between the arms 14 and 15 and made of thermal insulating material.
The top of each U-shaped support 8i, 9i may be associated with a metal head 8t, 9t thermally insulated from the arms 14, 15. Looking now in more detail at the thermal insulation or thermal break block
12, 12' (also made of polyamide for example), its structure comprises a main body 12a and a pair of facing arms 12b, 12c.
In particular, and purely by way of example, the main body 12a may have the shape of a parallelepiped with rounded corners (see Figure 7) and can be stably slotted into the cavity or seat 11, 11' in such a way as to occupy the cavity 11, 11' for the full depth S of the bottom base element 10, 10'.
The two above mentioned facing arms 12b, 12c are located at the top of the main body 12a, each forming a portion or section of one of the two arms 14, 15 of each pair of arms constituting the body of the track 8, 9, that is to say, the inner arm 14 of each pair 14, 15, so as to allow the body of the track 8, 9 to provide a thermal break while at the same time enabling each arm 14, 15 to extend lengthways uninterruptedly. In other terms, the cavity or seat 11, 11' is obtained by also removing a part of the two inner arms 14 which are substituted with the thermal insulating part of the block 12, 12'. A profile 7, 7' of this kind can be obtained in the following steps:
- making a profile 7 provided with thermal insulation or thermal break means 13 along the full length of the profile 7 and covering also the tracks 8, 9 (see also Figure 3);
- making a cavity or seat 11 in the profile 7 through its full depth S and extending transversally of the tracks 8 and 9 (see Figure 7);
- stably slotting into the cavity or seat 11 the thermal insulation or thermal break block 12, a part of which is shaped to match the cavity or seat 11 (see Figures 4, 5, 7 and 8 and arrows F12).
As shown in Figures 3 and 7, the step of making the cavity or seat 11 is obtained by removing material from a zone in the middle of the profile 7, including an inner part of the tracks 8, 9.
The method also includes a step of applying to each track 8, 9 a respective internal support 8i, 9i in the shape of an upturned U fitted inside the tracks 8, 9 and having a rounded head 8t, 9t which supports the carriages 21 and 22 and on which the latter slide (see arrows F8 and F9, Figure 8).
Each of the supports 8i, 9i is a single block made of thermal insulating material.
Figure 9 shows a sliding door/window 1 obtained from the profile 7 described to here. As stated above, the door/window 1 illustrated is made up of:
- a fixed frame 2 comprising two horizontal members 3, 4 and two vertical members 5, 6 and where the first bottom horizontal member 3 is defined by the profile 7 and comprises two parallel sliding tracks 8, 9;
- a mobile frame or first sash 20 that opens and closes by sliding horizontally relative to the fixed frame 2 on a first track 8 and by means of the carriages 21 and 22.
The profile 7 constituting the bottom horizontal member 3 comprises:
- the cavity or seat 11 formed in the profile 7 through its full depth S, extending transversally of the tracks 8, 9 and adapted to stably accommodate - the thermal insulation or thermal break block 12, a part of which is shaped to match the cavity or seat 11 and which also acts on at least one part of the tracks 8, 9; and thermal insulation means 13 acting longitudinally along the full length L of the bottom element 10 of the profile 7 and acting also on the tracks 8, 9. Similarly, the top horizontal member 4 of the fixed frame 2 is comprised of a profile 7' comprising the cavity or seat 11' formed in the profile T through its full depth, also extending transversally of the tracks 8, 9 and adapted to stably accommodate the thermal insulation or thermal break block 12', a part of which is shaped to match the cavity or seat 11' and which acts also on at least a part of the tracks 8, 9.
The top horizontal member 4 is also provided with thermal insulation means 13' acting longitudinally along the full length L of the bottom element 10' of the profile T and acting also on the tracks 8 and 9.
This structure of the horizontal frame members 3 and 4 significantly improves the thermal efficiency of the entire door/window 1, acting also in conjunction with seals 2Og located on the edges of the two frames 20 and 23 (see
Figure 6), optimizing the thermal seal along the profiles 7, T so as to form a sort of uninterrupted "sealing wall" extending from the bottom of the profile 7 constituting the bottom horizontal member 3 to the top of the profile T constituting the top horizontal member 4 thanks to the seals, of known type, located on the frames 20 and 23.
A profile made in this way achieves the above mentioned aims through a simple modification to the structure of traditional profiles.
The modification makes it possible to improve thermal efficiency over that of traditional profiles.
Thus, the partial break in the lower tracks and, if necessary, in the upper tracks, creates an effective thermal barrier having, for each outside facing surface, an uninterrupted thermal break system between inside and outside.
To this must be added the possibility of applying thermal insulation means to act on the profile and which improve thermal efficiency by creating specific thermal barriers.
In short, the profile and the method used to make it offer a number advantages that can be summed up as follows:
- overall improved thermal efficiency of the sliding door/window installed; - limited amount of processing required on the frame profile compared to the results obtained;
- simplification of the process for making the door/window as a whole.
The invention described above is susceptible of industrial application and may be modified and adapted in several ways without thereby departing from the scope of the inventive concept. Moreover, all details of the invention may be substituted by technically equivalent elements.
