    Corner piece for joining metal profiles together at a right angle, combination of metal profiles and such a corner piece, frame for a window or door and use of such a corner piece.
    The present invention relates to a corner piece for joining metal profiles to each other at a right angle, to a combination of metal profiles and such a corner piece, to a frame for a window or door and to the use of such a corner piece.
    Metal profiles, such as aluminum window profiles, for example, often have to be connected to each other at an angle.
    Traditionally, this is done by sawing the profiles into a miter, sliding a corner piece into them, and then deforming the profiles locally at the corresponding recesses in the corner piece, so that the profiles are clamped and pulled towards each other so that the miter is pulled shut. The distortion provides an immediate connection.
    Such a corner piece fits relatively precisely into the profiles, in other words the inner cavity of the profiles and the corner piece have a shape and size that are adapted to each other. Because it must of course be possible to insert the corner piece into the profiles, it is inevitable that there is a clearance.
    The said deformation is normally done by a press. Alternatively, the miter can be closed by screwing.
    After this, through specially provided holes in the profiles, glue is injected into the profiles at the location of the joint to ensure a firm long-term joint and to seal the seam between the two profiles.
    There are several disadvantages to the traditional method, namely the following: • It is generally a relatively long-term operation to attach the profiles to each other by means of screws or deforming with the aid of the corner piece, and therefore relatively expensive. • In the case of presses, a relatively expensive and heavy press must also be provided, so that the profiles to be connected and the corner piece must be brought to the press in a assembled but not yet connected state, which must of course be done with care and also takes time. • A distracted disadvantage here is that pressing can only take place in an equipped workshop, and not at any place. • Until the pressing or screwing has taken place, there is a certain freedom of movement due to the play of the corner pieces in the profiles, so that the assembled profiles and corner pieces do not form a stable unit and must therefore be treated with great care. • It can easily happen that, due to the necessary clearance to fit the corner pieces in the profiles, the viewing surfaces of the profiles do not lie in the same plane, so that extra attention must be paid to this.
    The present invention has for its object to provide a solution to the aforementioned and other disadvantages in that it provides a corner piece for joining metal profiles together at a right angle, the corner piece comprising a first leg parallel to a first geometric axis and includes a second leg extending parallel to a second geometric axis, the first and second geometric axes being perpendicular to each other, the first leg having a first outer surface and a second outer surface, both running parallel to the first geometric axis shaft and making an angle, preferably of about 90 °, with each other, the first leg being provided with a spring with one or more spring arms protruding from the first leg with an end and which is or are arranged around a first spring force to exert that has a component perpendicular to the first geometric axis, the first spring force having both a component that hook s is on the first outer surface if it has a component that is perpendicular to the second outer surface.
    The spring arms are here arranged as push springs, that is to say springs which are adapted to be pressed under an external force and then to exert an opposite spring force as a result of the depression.
    For the sake of clarity, it is stated here that with an end protruding outside the first leg, an end is meant that protrudes outside the circumference of the first leg in a cross-section perpendicular to the first geometric axis.
    The invention has the advantage that the corner piece can be slid easily and quickly into a profile and can then be clamped in two directions by the first spring force, so that freedom of movement of the corner piece relative to the profile is avoided.
    To this end, the opening in the profile must of course be of such shape and size that the end of the one or more spring arms rests against the inner wall of the profile and is thereby compressed, so that the first and second outer surface are pushed against corresponding inner surfaces by the different components of the first resilience.
    As a result, making a first connection between two profiles before gluing is considerably simplified compared to the known methods for joining profiles.
    The risk that two profiles are not completely parallel here, so that the viewing surfaces are staggered, is hereby reduced.
    Also, no complex, expensive or heavy attachments or tools are needed, and therefore there is great flexibility with regard to the location where the process is carried out.
    In a preferred embodiment, the one or more spring arms are designed as a wire spring with a spring steel spring wire extending from its attachment point to the corner piece to its free end in a direction that makes an angle with both the first outer surface and the second outer surface.
    Preferably, the ratio between the angle that the spring wire makes with the first outer surface and the angle that the spring wire makes with the second outer surface is between 0.25 and 4.
    As a result, each spring arm can individually exert a spring force with both components mentioned, so that a simple embodiment is obtained in which it is even possible to obtain the required direction of the spring force with a single spring arm. Of course, multiple spring wires can also be used, which may or may not work in the same direction.
    In yet another preferred embodiment, the one or more spring arms make an angle with a line from the point of contact of the legs to the end of the first leg, the angle with this line on the side of said point of contact being less than 90 °.
    In this way it is obtained that the corner piece can easily be slid into the profiles, wherein the spring arms can slide over the inside of the profiles under tension, while a reverse movement is made impossible because the spring arms then lock themselves into the profiles. As a result, once assembled corner joints remain stable with a low risk of disintegration before the adhesive is applied for a permanent joint.
    For this purpose, in a preferred embodiment, the one or more spring arms is or are provided at the said end with a sharp point or sharp edge, which further enhances such an effect.
    In a further preferred embodiment, the second leg has a third outer surface and a fourth outer surface, both running parallel to the second geometric axis and making an angle with each other, the second leg also being provided with one or more analogous spring arms.
    The invention further relates to a combination of a corner piece according to the invention and two or more profiles for a window frame or door frame, wherein the profiles are provided with an internal cavity, the legs of the corner piece and the internal cavities of the profiles having a complementary shape .
    The invention also relates to a frame for a window or door, wherein the frame is composed of profiles, wherein at least two of these profiles are perpendicular to each other with the aid of a corner piece according to the invention, which is slid into these profiles.
    The invention furthermore relates to the use of a corner piece according to the invention for joining two profiles together at an angle in the manufacture of a window or door frame,
    It is noted that the expression that two elements make an angle with each other means that they do not run parallel, and thus make an angle other than 0 ° with each other.
    With the insight to better demonstrate the characteristics of the invention, a preferred embodiment of a corner piece according to the invention is described below as an example without any limiting character, with reference to the accompanying drawings, in which:
    Figure 1 schematically and in perspective represents a corner piece according to the invention in a dismantled state;
    Figure 2 shows the corner piece of Figure 1 in a view according to F2;
    Figure 3 shows the corner piece of the previous figures in a side view according to F3;
    Figure 4 shows the corner piece of the previous figures in a section according to IV-IV; and
    Figure 5 shows the operation of a corner piece according to Figure 1.
    The corner piece 1 of figures 1 to 4 is made of metal, for example steel or aluminum or zamak, and consists essentially of two connected legs which make an angle of 90 ° with each other, namely a first leg 2 and a second leg 3 .
    The first leg 2 extends parallel to a first geometric reference axis 4 and the second leg 3 extends parallel to a second geometric reference axis 5.
    Both legs 2, 3 have a cross-section, so a cross-section perpendicular to the first reference axis 4, or second reference axis 5, with a substantially rectangular circumference.
    The first leg 2 has a first outer surface 6 and a second outer surface 7 which are perpendicular to each other and which run parallel to the first reference axis 4. The second leg 3 has a third outer surface 8 and a fourth outer surface 9 which are perpendicular to each other and which running parallel to the second reference axis 5.
    Both legs 2, 3 are provided with a cavity 10. In each cavity 10 is arranged a wire spring 11 with two spring arms 12. The springs 11 are arranged behind two catches 13 per leg 2, 3 and under a lip 14 in order to be able to properly confirm. The spring arms 12 are provided with a sharp point at their end 15, which end 15 projects beyond the circumference of the relevant leg 2, 3.
    The spring arms 12 in the first leg 2 extend, from their point of attachment to the first leg 2 to their end 15, in an oblique direction which makes an angle α of approximately 55 ° with the first outer surface 6 and which makes an angle β of approximately 35 ° with the second outer surface 7.
    This means that the spring arms 12 in the first leg 2, when they are compressed from the end 15, exert an inclined force, and thus have a component perpendicular to the first outer surface 2 and a component perpendicular to the second outer surface 3. The two spring arms 12 in the first leg 2 have the same direction relative to each other and, if they are compressed to the same extent, also exert a spring force in the same direction.
    Analogously, the spring arms 12 in the second leg 3 extend in an oblique direction with an angle of approximately 55 ° with the third outer surface 8 and an angle of approximately 35 ° with the fourth outer surface 9 so that, when compressed, they exerting resilience having a component perpendicular to the third outer surface 8 and a component perpendicular to the fourth outer surface 9.
    The spring arms 12 in the first leg 2 are each at an angle other than 90 ° with the first reference axis 4, and the spring arms 12 in the second leg 3 are each at an angle other than 90 ° with the second reference axis 5. Here, the angle γ of the spring arms 12 with the relevant reference axis 4, 5 of less than 90 ° directed to the point of contact of the two reference axes 4, 5, and the angle away from that point of contact of course greater than 90 °.
    Although in this example both spring arms 12 make the same angle γ with the relevant reference axis 4, 5, it is also possible that both spring arms 12 in a leg 2, 3 have a mutually different angle γ.
    The use of the corner piece 1 is simple and as follows, as illustrated with reference to Figure 5.
    The corner piece 1 is used together with two profiles 16. These profiles 16 and the corner piece 1 must be adapted to each other, mainly with regard to the cross-sectional shape of the legs 2, 3 and the shape of an internal cavity 17 in the profiles. Namely, this shape must be complementary, the cavity 17 being slightly larger than the legs 2, 3, so that the legs 2, 3 can be introduced into the cavities 17 rather fittingly.
    When inserting a leg, in this example the first leg 2, of the corner piece 1 into a profile 3.7, the spring arms 12 are pressed. As a result, they first bend in the direction of the other leg, in this example the second leg 3, and second they exert a force F with a direction from their end 15 to the attachment point 13, 14 of the spring arms 12 on the first leg 2, and thereby with a force component F] perpendicular to the first outer surface 6 and a force component F2 perpendicular to the second outer surface 7.
    As shown in Fig. 5, the first and second outer surface 6, 7 are hereby firmly pressed against the corresponding inner surfaces of the profile 16, so that a strong connection is obtained which does not allow freedom of movement in two perpendicular directions.
    Hereby some play is created on the opposite side between the profile 16 and the corner piece 1, as shown in figure 5.
    As soon as the corner piece 1 has been fitted, the corner piece 1 is firmly attached and it is only very difficult to remove.
    This is the case because with a removal force of the corner piece 1 from the profile 16, the ends 15 of the spring arms 12 engage in their profile 16 through their pointedness, so that a removal movement cannot take place.
    Also, any further removal force is converted into an increased force F, F 1, F 2 of the corner piece on both the first and the second outer surface 6, 7, so that a force to remove the corner piece 1 from the profile 16 provides a more robust attachment of the corner piece 1. in profile 16.
    What has been explained above with regard to the operation and use of the first leg 2 naturally applies analogously to the second leg 3.
    It is noted that in Figure 5 a simple rectangular profile 16 is shown. In practice, the corner piece 1 according to the invention will mainly be used for joining window or door profiles, which naturally have a much more complex shape.
    The present invention is by no means limited to the embodiments described as examples and shown in the figures, but a corner piece according to the invention can be realized in all shapes and dimensions without departing from the scope of the invention.
