Method for making a corner joint and corner piece applied thereby

Description

[0001] The present invention concerns a method for making a corner joint and a corner piece applied thereby.

[0002] In particular, the invention aims a corner joint or a T-joint in the joinery of a window, a door, a glass panel or the like, composed of hollow jambs which are connected by means of a corner piece.

[0003] Corner pieces provided with legs which are provided in the cavities of the respective jambs to be connected are already known.

[0004] Conventionally, such corner joints are made by first mitring the far ends of said jambs which are to be placed against one another, after which the legs of the corner piece are shoved in the far ends of the jambs and are fixed to them, for example by means of screws or by plastic deformation of the jambs.

[0005] In order to obtain an even firmer connection, glue is sometimes additionally injected.

[0006] The known jambs are divided in several chambers, defined by one or several partition walls.

[0007] Usually, such corner joints are made by means of several corner pieces for connecting several chambers of the jambs.

[0008] Use must hereby be made of different corner pieces whose outer perimeter of the legs is selected as a function of the chambers to be connected.

[0009] A disadvantage of the known method is that many separate components are required for making a corner joint, resulting in a complex assembly which moreover can only be automated with great difficulty.

[0010] More prior art can be found in WO-A-99/67495, which discloses a method according to the preamble of claim 1.

[0011] The present invention aims to remedy one or several of the above-mentioned and/or other disadvantages by providing a method according to claim 1.

[0012] An advantage is that this method for obtaining a connection requires less components, as a result of which the assembly is less complex and thus can be more easily automated.

[0013] Another advantage is that the thus obtained corner joint is more rigid.

[0014] The present invention also concerns a system according to claim 6 and the use according to claim 11.

[0015] In order to better explain the characteristics of the invention, the following preferred method according to the invention is described by way of example only without being limitative in any way, as well as an accompanying corner piece according to the invention, with reference to the accompanying drawings, in which:

figure 1 schematically represents two jambs and a corner piece according to the invention, seen in perspective;

figure 2 represents a section according to line II-II in figure 1;

figure 3 represents a view of the corner joint according to arrow F3 in figure 1;

figure 4 represents a section according to line IV-IV in figure 3;

figure 5 represents an alternative embodiment of the corner piece of figure 1.

[0016] Figure 1 schematically represents two hollow jambs 1 which are connected by means of a corner piece 2 according to the invention, which jambs 1 are divided in several chambers 3 in the known manner.

[0017] From the section of figure 2 it is clear that, in the given embodiment, every jamb 1 is composed of an outer jamb 4 and an inner jamb 5, which can be made for example of aluminium, metal, plastic or the like, and of one or several insulation jambs 6 connecting the above-mentioned inner jamb 5 and outer jamb 4.

[0018] This construction divides the jamb 1 in several chambers 3. Although in the given embodiment the chambers 3 are formed of the walls 7 of the sectional jambs, it is not excluded according to the invention for the cavity in for example the outer or inner jamb to be further divided in chambers by means of additional partition walls.

[0019] For the connection of the jambs 1, use is made of a corner piece 2 which, in the given embodiment, is built of an L-shaped body 8 with legs 9, standing at right angles to one another in this case, as is illustrated in figure 1.

[0020] According to a preferred characteristic of the invention, the legs 9 are made of several pieces and they are provided with parallel moulds 10 which can be shoved and fixed in the corresponding chambers 3 of the jambs 1.

[0021] The above-mentioned moulds 10 preferably have an appropriate shape in relation to the chambers 3, and the different moulds 10 of the corner piece 2 are preferably connected to one another, for example by means of cross connections 11 in the shape of partitions, narrower ribs or the like.

[0022] The method for making a corner joint by means of a corner piece 2 according to the invention is very simple and as follows.

[0023] First, the far ends of the jambs 1 to be connected are mitred in a known manner.

[0024] Before providing the corner piece 2 in the above-mentioned far ends, in case the moulds 10 of the corner piece 2 are connected by means of partitions 11 or the like, the partition walls 12 between the chambers 3 situated at the mitred far ends are removed, for example by milling or the like, such that the different chambers 3 which were initially present in the jamb 1 are locally transformed into one large chamber 13.

[0025] By locally removing the partition walls 12 between the chambers 3 space is made available for the partitions 11 of the corner piece 2.

[0026] It will be clear to the expert that, by locally removing the partition walls or by locally interrupting the partition walls 12 or by milling away the partition walls 12 entirely, a corner joint with only one corner piece 2 can be obtained.

[0027] Also, in a subsequent step, the legs 9 of the corner piece 2 can be pushed in the far ends of the jambs 1.

[0028] In a practical embodiment of the invention, the legs 9 of the corner piece 2 are made of several parts, and the legs 9 are shaped such that they simultaneously extend in several chambers 3 of the jambs 1 to be connected.

[0029] Finally, the corner piece 2 can be fixed to these jambs 1, for example by means of one or several screws 15 provided through passages 16 in the jambs 1 which have been made beforehand, and which are screwed down in the legs 9 of the corner piece 2.

[0030] The corner piece 2 can also be fixed in all sorts of alternative manners to the jambs, for example by means of plastic deformation of the far ends of the jambs, gluing or the like.

[0031] In another practical embodiment of the corner piece 2 which is represented in figure 5, the outer shape of the body 8 of said corner piece 2 is provided with a mould 10, corresponding to the outer mould 17 of the jambs 1 to be connected, such that a part of the corner piece 2 can be observed from the outside of the obtained corner joint.

[0032] When making a corner joint by means of this alternative corner piece, the outer mould 17 on the far ends of the jambs 1 to be connected will be locally removed in order to mount said corner piece 2, such that space is created for the body 8 of the corner piece 2.

[0033] It is clear that a possible variant of the corner piece 2 can be used for T-joints instead of corner joints.

[0034] The present invention is by no means restricted to the variants described by way of example and represented in the accompanying drawings; on the contrary, such a method for making a corner joint and a corner piece applied thereby can be made according to several variants while still remaining within the scope of the invention.
