Description

Corner piece for connecting metal window or door profiles at an angle to one another and the use thereof.
The present invention relates to a [corner piece] for connecting metal window or door profiles at an angle, preferably a right angle, to one another and the use thereof and the use of such a corner piece. Metal profiles, such as aluminium window profiles for example, often have to be connected together at an angle.
Traditionally this is done by mitring the profiles, inserting a corner piece therein, and then deforming the profiles locally at the level of corresponding cutaways in the corner piece, so that the profiles are clamped and pulled together so that the mitre joints are pulled shut. The deformation ensures an immediate joint. Such a corner piece fits relatively precisely in the profiles, in other words the inside cavity of the profiles and the corner piece have a shape and size that are adapted to one another. Because the corner piece has to be able to be placed in the profiles of course, it is inevitable that there is some play.
The said deforming is normally done by a press. Alternatively the mitre joints can be pulled shut by screws . After this, adhesive is injected in the corner pieces via holes specifically made in the profiles at the location of the joint to ensure a sturdy joint in the long term and to seal the seam between the two profiles.
To this end the corner pieces are provided with an internal hollow space for the distribution of injected adhesive and with channels on the surface to spread the adhesive so that a large area can be glued. It goes without saying that passages are provided for the flow of the adhesive from the internal space to the external channels, and inlet channels are provided to be able to inject adhesive in the internal space, normally at least one on each of the two arms of the corner piece.
In practice the adhesive is injected in the inlet channel of one of the arms, whereby adhesive is injected until the adhesive flows from the inlet channel to the other arm, whereby it is assumed that sufficient adhesive is injected to fill the external channels via the internal space and the passages and thereby to obtain a good joint.
However, this has the disadvantage that adhesive can already flow out of the inlet channel before this condition is satisfied, in other words before sufficient adhesive has been injected. This of course leads to mechanical weakness, or incomplete sealing of the mitre joint.
EP1911925 describes a solution for this problem by constructing the internal cavity as a valve that closes off the inlet channel along which no adhesive is injected. This is of course a relatively complex and fault-sensitive solution due to the moving parts. The purpose of the present invention is to provide a solution to the aforementioned and other disadvantages, by providing a corner piece for connecting metal window or door profiles at an angle to one another, whereby the corner piece is provided with one or more external channels for spreading adhesive, whereby the external channels are on the surface of the corner piece, whereby the corner piece is provided with two or more inlet channels that run inwards from the surface of the corner piece, whereby the corner piece is provided with one or more passages that run from the two or more inlet channels to the external channels, whereby the lowest flow resistance of the two or more inlet channels is greater than the lowest flow resistance of the one or more passages. The flow resistance is the pressure loss in a liquid that flows through the passages or inlet channels under standard conditions .
It may be clear that if the two inlet channels are identical, they have an identical flow resistance.
The flow resistance is essentially dependent on the diameter, length, surface roughness and the number of bends in the passages or inlet channels. In particular the length and diameter are suitable for giving the inlet channels a high flow resistance.
Hence, alternatively it can be said that the invention provides a corner piece for connecting metal window or door profiles at an angle to one another, whereby the corner piece is provided with one or more external channels for spreading adhesive, whereby the external channels are on the surface of the corner piece, whereby the corner piece is provided with two or more inlet channels that run inwards from the surface of the corner piece, whereby the corner piece is provided with one or more passages that run from the two or more inlet channels to the external channels, whereby the smallest flow-through opening of the one or more inlet channels is smaller than the smallest flow-through opening of the one or more passages.
For clarity it is noted here that the size of the flow- through opening is the area of a cross-section transverse to the longitudinal direction of the inlet channel or the passage, whereby this flow-through opening can be of a different size in different places in the channel or the passage . The invention has the advantage that adhesive flows from the inside to the outside through the inlet channel with greater difficulty than through the passage with the lowest flow resistance, so that the risk is limited that adhesive can flow from the inside to the outside through the inlet channel before the internal space and/or the external channels are sufficiently filled with adhesive supplied via the passage concerned.
Preferably the lowest flow resistance of the two or more inlet channels is greater than the highest flow resistance of the one or more passages, such that the advantage occurs with regard to all passages and the external channels thereby supplied.
In order to be more certain of this, in a preferred embodiment the lowest flow resistance of the two or more inlet channels is greater than the lowest flow resistance of the one or more external channels.
In a preferred embodiment the one or more inlet channels have a smaller flow-through opening at a distance from the surface than at the surface. This has the advantage that a relatively large nozzle can be used for applying adhesive, while the effect of the invention is nonetheless obtained.
In a preferred embodiment, the one or more inlet channels have a gradually decreasing flow-through opening, over at least a part of their length, in the direction from the surface to the inside.
As a result, upon injection the flow of the adhesive is only impeded to a limited extent. In a further preferred embodiment the smallest flow-through opening of the one or more inlet channels is at the transition between the internal space and the inlet channel or the flow-through opening of the one and more inlet channels decreases stepwise in the direction from the internal space to the surface.
As a result the flow of the adhesive through the inlet channel to the outside is additionally impeded.
As a result the smallest flow-through opening of the one or more inlet channels can be chosen to be as large as possible, while the effect is preserved. In other words, an optimum balance can be found between making the smallest flow-through opening as large as possible, which is desirable to be able to inject adhesive as easily as possible, and increasing the flow resistance in the reverse direction.
The invention also concerns the use of a corner piece as described above for producing a window frame or door frame of metal profiles.
With the intention of better showing the characteristics of the invention, preferred embodiments of a corner piece according to the invention are described hereinafter as examples, without any limiting nature, with reference to the accompanying drawings, wherein:
Figure 1 schematically shows a perspective view of a corner piece according to the invention;
Figure 2 shows the corner piece of figure 1 in a cross-section according to II-II; Figure 3 shows the part of figure 2 indicated by F3 on a larger scale;
Figure 4 shows the use of the corner piece of figure l;
Figure 5 schematically shows a perspective view of an alternative corner piece according to the invention; Figure 6 shows the corner piece of figure 5 in a cross-section according to VI -VI ;
Figure 7 shows the part of figure 6 indicated by F7 on a larger scale; and
Figures 8 and 9 show a second alternative corner piece according to the invention in cross-sections analogous to those of figures 6 and 7. The corner piece 1 of figures 1 to 4 is made of metal, for examples steel or aluminium or zamak, and essentially consists of two arms connected together that make an angle of 90° to one another. The corner piece is made of two halves 2,3 that are placed against one another to form the corner piece.
The corner piece 1 is provided with a distribution and spreading network for adhesive. In practice, this consists of external channels 4 that are made as deepenings in the surface 5 of the corner piece 1, an internal hollow space 6 , two inlet channels 7A, 7B and passages 8 from the hollow space 6 to the external channels 4 . s is particularly clear from figure 3, the inlet channels 7A, 7B are conical and have a diameter d that decreases linearly from the outside to the inside. This means that the smallest diameter dm, and as a result of this the smallest flow-through opening, of these inlet channels 7A, 7B are at the connection with the internal space 6.
The passages 8 between the internal space 6 and the external channels 4 each have a diameter ddi and dd2 that is substantially larger than the smallest diameter dm of the inlet channels 7A, 7B and thereby have a flow-through opening that is substantially larger than the smallest flow-through opening of the inlet channels 7A, 7B.
As a result, the flow resistance of the passages 8 is substantially lower than the flow resistance of the inlet channels 7A, 7B.
The external channels 4 also have a larger flow-through opening than the smallest flow-through opening of the inlet channels 7A, 7B.
The use of the corner piece 1 is simple and as follows, and is illustrated in figure 4.
Two mitred profiles 9 for a window are each slid around another arm of the corner piece 1. Holes 10A, 10B are made in the profiles 9 at the place that corresponds to the location of the inlet channels 7A, 7B. This situation is shown in figure 4. Now the profiles are deformed locally against the corner piece 1 to pull the mitre joint shut. This is known to the person skilled in the art and hence is not shown. Then a nozzle that is connected to an adhesive reservoir is placed in the accompanying inlet channel 7A, through one of the holes 10A, and adhesive is injected in the inlet channel 7A. Due to the conical shape of this inlet channel 7A this proceeds without significant impedance. This adhesive is spread via the internal space 6 and the passages 8 to the external channels 4. The adhesive will also flow from the inside to the outside through the other inlet channel 7B.
Due to the small flow-through opening of the inlet channels 7A, 7B, compared to the flow-through opening of the passages 8 and the external channels 4, this will be done slowly such that the external channels 4 are already completely or practically completely filled with adhesive before adhesive flows out of the other hole 10B, which is the signal for the operator to stop the injection of adhesive . The corner piece 1 shown in figures 5 to 7 essentially has the following differences to the above corner piece 1:
• The cross-section of the arms have a much more rectangular shape than the approximately square arms of the first corner piece 1;
· The corner piece 1 consists of two parts 2,3 that are of a highly different size, in contrast to the practically equally large parts 2,3 of the first corner piece;
• The inlet channels 7 are not straight, but curved, and they have a more elongated cross-section.
Thee cross-section, and as a result the flow-through opening of the inlet channels 7, gradually decreases from the outside to the inside, just as with the first embodiment, and thus from the surface 5 to the internal space 6.
Due to their length and their curved shape, these inlet channels have a higher flow resistance than would be expected just on the basis of their diameter.
The use of this corner piece 1 is analogous to the corner piece described above.
The corner piece 1 shown in figures 8 and 9 essentially differs from the previous corner pieces 1 in that the inlet channels 7A, 7B are made very long and with bends, to have a high flow resistance specifically due to their length and bends . More specifically the length L of the inlet channels 7A, 7B, measured along their centre line 11, is approximately 180% of the shortest distance A between the ends of an inlet channel 7A, 7B. The present invention is by no means limited to the embodiments described as an example and shown in the drawings, but a corner piece according to the invention can be realised in all kinds of forms and dimensions, without departing from the scope of the invention.
