Description

Window structure with a fitting for assembling the corners of the window sash
The invention concerns a window structure having a sash made from profiles comprising a part made from a plastic or fibre glass material, said profiles are connected in mitre joints, and said profiles comprise a slit in the part made from a plastic or fibre glass material, into which slit a fitting being arranged, said fitting is prepared for assembling two profile parts of a window sash, said fitting comprising two interconnected legs each comprising an insertion portion for being inserted into a slit of two juxtaposed profiles. The invention is further directed at the fitting for assembling two profile parts of a window sash, and to a method for assembling the window structure.
The application of composite profiles for window frames and for a sash supporting the window pane is known. Such profiles would typically be made from metal, e.g. aluminium, on the part supporting the glass pane and the outdoor part. The indoor facing part is preferably made from plastic or fibre glass. The advantage is that the strength and durability of the metal is combined with the lower thermal conductivity of the plastic or fibre glass material. However, the whole sash profile may be plastic or fibre glass. The preferably four profile parts making up e.g. the sash is preferably connected in mitre joints. Angle pieces for securing the connections are often placed within the profile, preferably in the metal part of the profile.
The part of the profile facing the indoor side, e.g. the plastic or glass fibre part of the profile, is not necessarily connected in the corners, e.g. mitre joints, but may simply abut against each other. Since the profiles may expand and contract in dependence on temperature variations, this may lead to gaps in the corners of the sash between two profiles. These gaps are visible when the window is open. Even if the corners of plastic or fibre glass part of the profiles were glued together, such gluing would often not be able to hold to the continuous expansions and contractions of the profiles, and may eventually break such that a gap in the comers would occur.
The objective of the present invention has therefore been to find a solution for avoiding such gaps to occur. The solution is that the insertion portion of the fitting comprises teeth prepared for limiting relative movement between said profiles and said legs in a longitudinal direction of said leg, when said insertion portion in use being inserted into said slit.
In a preferred embodiment the window structure is having a sash made from profiles comprising a part made from a plastic or fibre glass material. The profiles are connected in mitre joints, and comprise a slit into which a fitting as described above is arranged. Preferably, the legs of the fitting are extending perpendicular or substantially perpendicular to each other, which is necessary in the case of a rectangular sash where the slits in the profile parts also form a rectangle.
In a preferred embodiment the insertion portion of the fitting comprises locking means for preventing accidental removal of said insertion portion once it has been inserted into the slit. These locking means may be integrated with the teeth such that the teeth have a part which is wider than the opening width of the slit. When the slit is made in an elastic material, the fitting can be introduced into the slit, but it will be prevented from accidental removal. In a preferred embodiment the teeth of the fitting is formed as barbs.
In a preferred embodiment the legs of the fitting comprises a base portion prepared for being outside said slit when the insertion portion is entered into said slit. Thereby the exact position of the fitting within the slit is controlled by the base portion. In a preferred embodiment the number of teeth on one leg arranged to face the same side surface of the slit, is at least 6, preferably at least 9 and more preferably at least 12. Increasing the number of teeth will increase the pulling strength of the profile which can be resisted.
In a preferred embodiment the window sash comprise four profiles each having a slit. The four profiles is assembled into a rectangle by mitre joints in each corner, where one fitting is arranged in each corner connecting the two juxtaposed slits.
The invention is now described in further detail with reference to embodiments in the figures.

Figure 10 illustrates the fitting arranged in a slit as in figure 7, in a perspective view.
Figure 1 - 7 shows an embodiment of the fitting 1 for assembling two profile parts of a window sash. The fitting 1 is provided with two legs 2, 3 extending perpendicular to each other. Each leg comprises an insertion portion 5 prepared for being inserted into a slit in the profile part. Said insertion portion 5 is extending in the longitudinal direction of the leg 2, 3.
Figure 8, 9 and 10 shows part of two profiles 30 for a window sash. The profiles 30 are each provided with a slit 31. The two profiles 30 are assembled in a mitre joint, and the slits 31 of the two profiles are juxtaposed such that a fitting 1 has been arranged in and is extending into the slit 31 of both profiles 30.
Each leg 2, 3 of the fitting comprises a number of teeth 11 , arranged as part of the insertion portion 5 and such that they will function as barbs when inserted in a slit of the profile parts. When the slit is arranged extending in the longitudinal direction of the profile, the teeth 11 will limit or prevent movement in the longitudinal direction of the leg 2, 3 to which the teeth 11 are attached. It should be mentioned that the cross sectional view shown in figure 9 is made between two teeth 11. The teeth 11 will take up a larger portion of the space in the slit 31 than figure 9 thus indicates. The dimensions of the insertion portion 5 is preferably such that when the fitting 1 is inserted in said slit of the profile, the sides of the slit will have a clamping effect on the insertion portion 5 of the fitting. Such a clamping effect ensures that there is a close contact between the teeth 11 and the sides of the slit. This is important for achieving the effect of the teeth 11 preventing or limiting relative movement between the fitting and the profile. In order to obtain a close contact, and to prevent movement in the longitudinal direction between the teeth and the slit, the material from which the teeth are made should preferably be harder than the material from which the sides of the slit is made. Preferably the teeth 11 of the fitting is made from metal, preferably the whole fitting is cast from a metal such as zinc.
The close contact between the teeth 11 and the side surfaces of the slit 31 may also be obtained by pressing the teeth 11 into the slit 31 such that each teeth cuts into the side surface of the slit 31.
The part of the window sash around the slit is often made from plastic or a fibre glass material.
The fitting for the window structure is preferably provided with a base portion 10 which may have several purposes. One purpose is to determine how far the insertion portion is inserted into the slit. This is obtained by the base portion 10 having dimensions such that it will not be able to enter into the slit in the profile part. Thereby, the insertion portion 5 of the fitting 1 can be pushed into the slit until a position where the base portion 10 abuts the surface of the window profile where the slit is arranged. Another purpose of the base portion is to provide a smooth outer surface, such that the fitting can be pushed into position by the fingers alone. At the same time the outer surface will typically be visible and accessible when the window is open, and therefore it is preferred for aesthetic reasons that the surface is smooth, and for safety reasons it is preferred that the sharp edges of the teeth are not accessible. This visible surface of the base portion 10 may be painted or covered by a plastic layer.
From figure 1 it is further seen that the teeth 11 are provided with a shape such that the width of the insertion part of a leg 2, 3 (width is here measured perpendicular to the longitudinal direction of the leg, and parallel with the plane in which the two legs 2, 3 extend) is relatively small at the top, which is the top part of the teeth 15 first introduced into the slit, i.e. the part arranged opposite the base portion 10 shown in figure 10. The bottom part of the teeth 17, placed next to the base portion 10, is preferably arranged to provide the insertion part 5 to be wider here than it is at the top. In between the top part 15 and the bottom part 17 of the teeth 11 , is an intermediate part 16 of the teeth, providing the insertion part being wider at this intermediate part 16, than at both the top part 15 and the bottom part 17.
This geometry of the teeth 11 is prepared for cooperating with the slit 31 in the profile 30 of the sash. Preferably, the slit 31 will be provided with lip parts 32 extending over the open part of the slit 31 at the entrance to the slit 30. This means that the width of the slit is relatively narrow at the surface in which the slit 31 is arranged, while the width expands and becomes relatively larger when moving further into the slit beyond said lip parts 32. The width of said lip parts 32 in the insertion direction is preferably arranged to be smaller than the distance between the base portion 10 of the fitting 1 and the wider intermediate part 16 of the insertion part of the fitting.
When introducing the insertion part 5 of the fitting 1 into such a slit 31 , the intermediate wide part 16 of the teeth 11 must be forced pass the lip part 32 of the slit. Once the intermediate wide part 16 has passed the lip part 32 of the slit 30, the insertion part 5 will be held by the lip parts 31 in a position inserted in the slit 31. It is seen from both figures 1 and 3 - 7 that the fitting 1 in an embodiment of the invention may comprise two different types of teeth. A first type of teeth 11 is relatively narrow at the top 15 as described above. A second type 12 of teeth is wider than the first type 11 at the top part 15. In this embodiment there will only be few teeth of the second type 12. The purpose of these second type teeth 12 is to offer the possibility of being able to place the fitting in the position where it is to be inserted into the slit, without inserting the fitting into the slit, but ensuring that it is fixed in the position. This possibility is important if the sash is assembled in an upright position, and the fitting 1 is of dimensions where it is necessary to apply tools, e.g. a hammer, for the insertion of the fitting 1 into the slit 31. Then it must be possible to secure the fitting 1 easily by the fingers, before the fitting 1 is finally inserted into the slit 31.
One example of a fitting 1 for the inventive window structure according to an embodiment of the invention is a fitting 1 consisting of two legs 2, 3 extending perpendicular to each other, and each leg having a length of 22 mm. The fitting 1 is cast from zinc. The diameter of the insertion part measured from the intermediate part 16 of the teeth 11 on one side of the insertion part 5 to the intermediate part 16 of the teeth 11 on the other side of the insertion part 5 is approximately 3.9 mm. This diameter will cooperate well with a width of the slit 31 , measured at the narrow point between the lip parts 32, of approximately 3.5 mm. These dimensions will ensure that the insertion part is locked into position once introduced into the slit 31. The number of teeth is preferably 12 - 16, more preferably around 14. The number of teeth is determining the maximum force of a contraction of the profile 30, which the fitting 1 will be capable of withstanding.
The teeth 11 are preferably arranged as barbs in order to resist pulling of the profile 30 away from the corner 4 interconnecting the two legs 2, 3 of the fitting 1. However, part of the teeth may be arranged otherwise in order to facilitate easy removal of the fitting from the casting mould.
The method for assembling a window structure comprises the steps of arranging two profile parts 30 of a window sash juxtaposed, said profile parts 30 comprise a slit 31 in a part made from a plastic or fibre glass material. In the method a fitting 1 as described above is inserted into the slit 31 of said profile parts 30. The slit 31 is made from a resilient material. During insertion the teeth 11 of said fitting 1 will force the sides of said slit 31 away from each other. Following this, the distance between the sides of said slit 31 will be decreased when inserting said fitting further into the slit.
