Abstract

Improved window or door jamb, characterised in that it mainly consists of a single plastic jamb (6 or 7) which is provided with a metal sheeting (15 and/or 16; 17 and/or 18) on one or both reveals.

Description

The present invention concerns an improved window or door jamb.
Window and door jambs which are composed of two aluminium jambs, an outer jamb and an inner jamb respectively, which are mutually connected by means of two thermally insulating connecting posts, are already known.
The above-mentioned thermally insulating connecting posts are hereby made such that they are connected to an inner jamb, outer jamb respectively with their free ends, for example by means of a dovetail connection.
Whereas the above-mentioned inner and outer jamb mainly fulfil the mechanical functions of the joinery, such as for example anchoring a glass plate or guiding a lock mechanism, the above-mentioned thermally insulating jambs' function is to prevent any heat transfer between the inside and the outside, or in other words to interrupt the thermal bridge.
A disadvantage of such known window and door jambs is that they are relatively expensive due to the cost price of the raw materials on the one hand, and because the extrusion dies for manufacturing such aluminium jambs are relatively expensive on the other hand.
Another disadvantage of such known jambs is that they are formed of a relatively large number of parts, whose assembly is relatively time-consuming.
An additional disadvantage of the known jambs is that practically all the mechanical functions are fulfilled by the aluminium jambs, such as for example guiding the parts of the lock mechanism and the like.
As a consequence, the space required therefore cannot be used as an insulation zone, such that improving the insulation by enlarging the insulation zone is only possible by enlarging the depth of the composed jamb.
Window or door jambs which are entirely made of plastic are already known as well.
Such plastic window and door jambs are disadvantageous in that they are less resistant to temperature stress such as extreme heat and/or cold, and in that they may discolour and weaken under the influence of sun light, rain and the like.
Also mechanically speaking, such plastic window and door jambs are not as strong as aluminium jambs, as a result of which they are for example less scratch-resistant.
The present invention aims to remedy one or several of the above-mentioned and other disadvantages.
To this end, the present invention concerns an improved window or door jamb which mainly consists of a single jamb made of plastic which is provided with a metal sheeting on one or on both reveals.
By the reveals of the window or door jamb are hereby meant those sides of the jamb which, when said jamb is mounted in a joinery, are visible on either side of said joinery.
An advantage of such an improved window or door jamb according to the invention is that it is cheaper than the known jambs, since it is largely made of plastic which can moreover be processed by means of relatively cheap extrusion dies.
Moreover, such improved window or door jambs consist of a limited number of parts, as a result of which the assembly is simpler compared to that of the known composed jambs with two thermally insulating connecting strips, and as a result of which such improved jambs are relatively rigid.
An additional advantage of such improved window or door jambs is that they have a good heat insulation, as they are largely made of plastic.
Another advantage of window or door jambs according to the invention is that, thanks to the presence of the aluminium sheeting, they have a good resistance against thermal influences such as extreme heat and/or cold, and that they can be exposed to sunlight, rain and the like without thereby discolouring and/or weakening.
Such improved jambs according to the invention also have a good scratch resistance.
Another advantage of such window and door jambs according to the invention is that they are aesthetic.
An additional advantage is that, for example, a window which is provided with window jambs according to the invention has the known good aesthetic qualities of existing aluminium windows.
In order to better explain the characteristics of the present invention, the following preferred embodiment of an improved window or door jamb according to the invention is represented, with reference to the accompanying drawings, in which:

figure 1 represents a partial section of a joinery which is provided with improved window jambs according to the invention;
figure 2 represents a variant of a joinery according to figure 1.

Figure 1 represents a joinery 1 of a window which mainly consists of a wing 2 and a casing 3 which are each provided with at least one improved window jamb 4, 5 respectively according to the invention, and whereby these respective window jambs 4 and 5 of the wing 2 and the casing 3 work in conjunction with each other.
Each of the above-mentioned window jambs 4 and 5 according to the invention mainly consists of a single jamb 6 or 7 made of plastic which is in this case formed of a rectangular socket with two cross walls 8 and 9 and two adjacent connecting walls 10 and 11 standing at right angles to the latter, in between which, in this case, a number of cross stiffening plates 12 have been provided.
When the joinery 1 is closed, the above-mentioned plastic jambs 6 and 7 are situated opposite each other.
At least on each of the sides of the connecting walls directed towards each other, and in this case on all the connecting walls 10 and 11 of the jambs 6 and 7, is provided at least one pair of parallel ribs 13 which extends in the longitudinal direction of the respective window jambs 4 and 5, whereby the free ends of these ribs 13 are folded towards each other.
In this case, on each of the connecting walls 10 and 11 of the plastic jambs 6 and 7, is also provided a second pair of parallel ribs 14 which also extends in the longitudinal direction of the respective window jambs 4 and 5, and whose free edges are folded towards each other as well.
According to the invention, each of the above-mentioned plastic jambs 6 and 7 is provided on one or both reveals A and B with a metal sheeting 15, 16, 17 or 18.
By the reveals A and B of the window jamb 4 or 5 are hereby meant those sides of the jamb 4 or 5 which, when said jamb 4 or 5 is mounted in a joinery 1, are visible on either side of this joinery 1.
In this case, each of the metal sheetings 15, 16, 17 and 18 is made in the shape of an aluminium jamb which is provided on a respective cross wall 8 or 9 of a plastic jamb 6 or 7 by means of gluing.
Each of the metal sheetings 15 and 16 on the reveal A of the joinery 1 is mainly made in the shape of a cylindrical jamb with four connecting side walls 19, whereby one of these side walls 19 is fixed to a cross wall 8 of a respective plastic jamb 6 or 7.
The metal sheeting 16 which is provided on the wing 2 of the window, on the reveal A of the joinery 1, is provided with a laterally protruding lath 20 which extends parallel or practically parallel to the cross wall 8 of the plastic jamb 7, such that the free edge of the above-mentioned lath 20 extends opposite an outer side wall 19 of the metal sheeting 15 on the jamb 6.
On the side of the above-mentioned lath 20 directed towards the casing 3, near the free edge, are provided two parallel ribs 21 which extend at a distance from each other in the longitudinal direction of the window jamb 4, which ribs 21 are provided with lips bent towards each other on their free ends.
The metal sheeting 17 which is provided on the reveal B of the joinery 1, on the jamb 6, consists of a first wall provided to the cross wall 9 and a second wall 23 parallel thereto, which is provided opposite the above-mentioned first wall 22 and which is connected thereto by means of two connecting walls 24.
The above-mentioned second wall 23 of the metal sheeting 17 extends to opposite the cross wall 9 of the plastic jamb 7 and is provided, on its side directed towards the jamb 7, near its free edge, with two parallel ribs 25 which extend in the longitudinal direction of the jamb 6, and whose free edges are bent towards each other.
The metal sheeting 18 which is provided on the reveal B of the joinery 1, on the cross wall 9 of the plastic jamb 7, consists of a lath 26 with a double buckle at the height of the connecting wall 11 and which extends past this connecting wall 11.
Near its free edge, the above-mentioned lath 26 is provided with two parallel ribs 27 with lips that are bent towards each other, which ribs extend in the longitudinal direction of the plastic jamb 7.
During the assembly of a joinery 1 according to the invention, a sealing strip 28 is clamped between the above-mentioned ribs 13 on the plastic jamb 6 of the casing 3, which forms a stop for at least one rib 13 of the plastic jamb 7 of the wing 2 provided opposite the latter.
Between the above-mentioned ribs 14 on the connecting wall 11 of the plastic jamb 7 is clamped a glazing bead 29, which secures a glass plate 30 to the above-mentioned lath 26 serving as an exterior glazing lip and which is provided with a sealing strip 31 to that end which is clamped between the above-mentioned ribs 27.
If necessary, the ribs 13 and 14 on the sides of the connecting walls 10 and 11 of the plastic jambs 6 and 7, which sides are directed towards each other, can be used as a conducting channel for the parts of a lock mechanism or the like which is not represented in the figures.
Figure 2 represents a variant of a joinery according to figure 1, which mainly has the same construction as the preceding embodiment, but whereby each of the plastic jambs 6 and 7, in this case on the reveal B of the joinery 1, is integrally provided with a laterally protruding lath 32, 33 respectively, which is parallel to or almost parallel to a cross wall 9 of the plastic jamb 6, 7 respectively concerned.
The lath 32 of the plastic jamb 6 extends to opposite the cross wall 9 of the plastic jamb 7, and on its side directed towards the jamb 7 it is provided with two parallel ribs 34 provided at a distance from one another, with far ends that are bent towards each other.
On the reveal B of the joinery 1, the above-mentioned lath 32 is in this case provided with a metal sheeting in the shape of a flat aluminium lath 35.
The lath 33 of the plastic jamb 7 extends, analogous to the lath 26 of the preceding embodiment, partly next to the connecting wall 11 of the plastic jamb 7, and it is provided with two parallel ribs 36 provided at a distance from each other near its free edge which extend in the longitudinal direction of the jamb 7 and which are provided with lips bent towards each other.
On the reveal B of the joinery 1, the above-mentioned lath 33 is covered with a metal lath 37.
The assembly of such an embodiment is analogous to that of the above-described embodiment, but, in this case, sealing strips 31 and 38 are provided between the ribs 36, 34 respectively of the plastic jambs 7, 6 respectively, and the lath 33 also forms the exterior glazing lip.
It is clear that an improved window or door jamb 4 according to the invention is not restricted to the use in the joinery of a window, but that it can be used for all sorts of joineries, such as for example for door frames or the like.
It is also clear that the above-mentioned metal sheeting 15, 16, 17 and 18 can be provided on the plastic jambs 6 or 7 in many ways, for example by means of gluing, rolling, clipping, screwing or a combination of these fastening techniques.
By rolling is meant here that the plastic jamb 6 or 7 and the metal sheeting 15, 16, 17 or 18 are connected to each other by means of a dovetail connection or the like, whereby a detail in the metal sheeting is clamped in the plastic jamb by deformation around a complementary detail.
It goes without saying that the above-mentioned sealing strip 28 cannot only be fixed to the casing jamb 4, but that it can also be provided on the wing jamb 5, or that a sealing strip can be provided on both jambs 4 and 5.
The metal sheetings 15, 16, 17 and/or 18 according to the invention can be made in all sorts of metal, and they are not restricted to aluminium.
According to the invention, it is not excluded to provide only a single rib 13 or 14 on one or several of the connecting walls 10 or 11 for fixing a sealing strip, which rib 13 or 14 extends in the longitudinal direction of the respective window jambs 4 or 5.
The present invention is by no means limited to the embodiments described above and represented in the accompanying drawings; on the contrary, an improved window or door jamb according to the invention can be made in all sorts of shapes and dimensions while still remaining within the scope of the invention.
