Description

DESCRIPTION

Extruded profile of hollow chamber for door or window

[0001] The invention relates to a hollow door or window chamber profile according to the preamble of claim 1.

[0002] In the already known fixing area, at least one screw is screwed, with which a joint with a hardware element is established or with which, alternatively, a base body joint is established with a connecting element, for example a jamb or a crossbar, as an external component. To guarantee a predefined extraction force of the fixing bolt, the fixing bolt, that is to say in the hollow chamber profiles 10 already known as a general rule, the screw, is screwed through at least one metal wall of the hollow chamber profile. Screws made only through plastic walls result in relatively small extraction forces in such configurations of the fixing area.

[0003] From US 5,622,017 A a hollow chamber profile is known according to the preamble of claim 1. In documents DE 93 21 396 U1 and US 2006/0096193 A1, similar hollow chamber profiles 15 are described. However, such hollow chamber profiles have the disadvantage that, by introducing the fixing bolt, the side walls are separated from each other.

[0004] Therefore, it is an objective of the present invention to improve a fixing area of a hollow chamber profile of an extruded door or window of the type mentioned at the beginning such that, when introducing the fixing bolt, it is prevented that the side walls are removed from each other although the front walls have a great separation from each other or even if the side walls, by virtue of their thickness or material, are made so that they are flexible.

[0005] This objective is achieved according to the invention by means of a hollow chamber profile with the characteristics indicated in the characterizing part of claim 1.

[0006] According to the invention it has been recognized that, although the front walls have a large separation between each other or even if the side walls are made so that they are flexible by virtue of their thickness or material, the side walls are secured so that they cannot be separated from each other when the fixing bolt is inserted if at least one intermediate rib is provided between the front walls of the chamber which extends parallel to the front walls.

[0007] According to the present invention, a fixing channel made entirely of plastic is provided transversely to the extrusion direction of a hollow chamber profile. This fixing channel is laterally delimited by two chamber side walls. Since the separation between them is smaller than the outer diameter of the fixing bolt, the peripheral profiling of the fixing bolt is introduced into the chamber side walls. This preferably occurs over the entire length of the chamber side walls adjacent to the fixing bolt. This ensures a good settling of the plastic fixing channel with the fixing bolt, as far as possible along its entire length or along a large part of its length, which leads to a large extraction force of the fixing bolt With the fastening zone according to the invention, high demands can be met regarding extraction with fastening zones made entirely of plastic, especially in relation to specifications due to anti-theft security.

[0008] In the embodiment of the fixing channel according to claim 2, with front chamber walls of different thickness, for example the thicker front wall can play a fastening function to hold the two chamber side walls together, while that the thinner front wall has a securing function, which prevents the side walls from separating from each other by introducing the fixing bolt. The chamber side walls according to claim 2, of different thickness, may also be different in function. Thus, the thicker side wall can have a supporting function, while the more flexible side wall, of smaller thickness, is used for settling with the peripheral profiling of the fixing bolt. An analogous division of functions of the front walls and / or the side walls is possible if these walls are made of different materials according to claim 3.

[0009] Reinforcement profiles according to claim 4 favor a lateral wall settling that presents the profiling with the peripheral profiling of the fixing bolt. fifty

[0010] By arching the side walls according to claim 5, a pre-tension of the side walls towards the fixing bolt is achieved when it is inserted. This pre-tension counteracts a tendency of the side walls to separate from the fixing bolt. It is preferred that both side walls be symmetrically curved into the chamber. As an alternative, it is also possible that only one of the two side walls is arched into the chamber. 55

[0011] A fixing channel produced according to claim 6 can be economically manufactured.

[0012] A fixing channel according to claim 7 allows subsequent equipment of an already manufactured profile.

[0013] A screw according to claim 8 has proven its effectiveness as a fixing bolt.

[0014] A fine thread screw according to claim 9 surprisingly leads to a very high extraction force of the fixing bolt of the fixing channel. 60

[0015] Screw parameters according to claims 10 to 12 also lead to an advantageously high extraction force. A very suitable screw as an example of a fixing bolt according to the invention is a screw for sheet metal DIN7981 or a screw for the manufacture of windows (FFB screw). The DIN7981 sheet screws have a pitch angle of 60 ° and a distance between fillets of 1.34 mm. The FFB screw has a pitch angle of 40 ° and a distance between steaks of 2.6 mm. 65

[0016] Next, some examples of embodiments of the invention are explained in more detail by means of the drawings. In these, they show:

- Figure 1 (not according to the present invention) a detail of a hollow chamber profile of an extruded door or window, an extrusion direction being perpendicular to the drawing plane, in a fixing zone for fixing a component external to the profile of hollow chamber; 5

- Figure 2 (not according to the present invention) a representation similar to Figure 1 of another embodiment of a fixing area, the chamber walls of the surrounding hollow chamber profile and the external component having been omitted;

- Figure 3 a representation similar to Figure 2 of another embodiment of a fixing area;

- Figure 4 a representation similar to Figure 2 of another embodiment of a fixing area; and 10

- Figures 5 to 7 (not according to the present invention) representations similar to figure 1 of other embodiments of fixing areas with the external component omitted.

[0017] A hollow door or window chamber profile 1, of which only a detail is shown in the drawings around a fixing area 2, has several hollow chambers between an inner door or window side and an outer door side or window, as it is already known in the current state of the art. fifteen

[0018] The fixing zone 2 is used to fix the hollow chamber profile 1 to or with an external component 3. The latter can be a door or window fitting. Alternatively, the external component 3 can be a door or window frame joining element, for example a jamb or a crossbar.

[0019] Figure 1 shows a first embodiment of the fixing zone 2. This has a fixing bolt 4, peripherally profiled, in the form of a screw with a screw body 5 and a thread 6 formed therein. The fixing bolt 4 may in particular be a fine screw. As an alternative to a screw, the fixing bolt 4 can also be made as a peripherally profiled bolt that is not to be screwed, but in particular to be nailed.

[0020] To introduce the fixing bolt 4, the hollow chamber profile 1 has a fixing channel 8, with a longitudinal axis of channel 9, extending transversely to an extrusion direction 7 extending 25 perpendicularly to the plane of the He drew. The fixing channel 8 is composed entirely of plastic. The fixing bolt 4 is inserted into the fixing channel 8 along the longitudinal axis 9. The fixing channel 8 is extruded in one piece with the rest of the hollow chamber profile 1. Perpendicular to the longitudinal axis of channel 9 and the extrusion direction 7, the fixing channel 8 is delimited by two chamber side walls 10, 11. A distance A between the chamber side walls 10, 11 is smaller than the outer diameter Da of the fixing bolt 4 30 predetermined by the external diameter of the thread 6. Therefore, in the area of the chamber side walls 10, 11, the thread 6 has been introduced at least partially into the chamber side walls 10, 11.

[0021] The screw, as an example of the fixing bolt 4, is characterized, in addition to its outer diameter Da, a diameter Di of the inner body of the bolt and a distance G between two adjacent fillets. The difference Da less Di is equal to twice a flank height of the thread 6. On the fixing bolt 4, this flank height is approximately 0.5 mm. Flank heights greater than 0.2 mm are preferred.

[0022] The distance G between adjacent fillets is a measure of a screw thread pitch, as an example of the fixing bolt 4. In the embodiment according to Figures 1 to 6, the thread pitch is approximately 40 °. This type of thread pitch is presented by FFB screws. FFB screws are also called coarse thread screws. A thread pitch that is less than 65 ° is preferred. A thread pitch of 60 ° is also possible, common in the 40 sheet metal screws.

[0023] A distance between two screw fillets, as an example of the fixing bolt 4, can be for example 1.5 mm. This is the case in the embodiment according to Figures 1 to 6. The distance between fillets can also be greater, for example 2.6 mm.

[0024] In its longitudinal direction, the fixing channel 8 is delimited by two front chamber walls 12, 13, 45 through which, in the example of figure 1, the bolt of fixing 4. Depending on the realization of the fixing bolt 4, steps are made through the front chamber walls 12, 13 before inserting the fixing bolt 4, or the fixing bolt 4, for example in case of If a cutting screw is used, the passages are created on the front walls of the chamber 12, 13.

[0025] The front chamber walls 12, 13 prevent the chamber side walls 50, 11 from being introduced from the fixing bolt 4, so that an introduction of peripheral profiling of the bolt is guaranteed. fixing 4, that is, for example, represented by the thread 6, in the side walls of the chamber 10, 11 in practically its entire length.

[0026] In the example of Figure 1, walls 10 to 13 form exactly a hollow fixing chamber 14.

[0027] Figures 2 to 7 show other embodiments of fixing zones 2. The components corresponding to those already explained above with reference to the embodiment according to Figure 1 bear the same reference numbers and will not be treated in detail again.

[0028] In the embodiment according to figure 2, the front chamber wall 13, which in said figure is represented in the lower part, does not form part of a chamber wall that extends outside the fixing area 2 transversely to the axis Longitudinal 9 of the channel, as in the embodiment according to Figure 1, but constitutes a junction rib between the chamber side walls 10, 11 that closes the fixing channel 8 downwards. The junction rib 13 has a wall thickness less than that of the upper chamber front wall 12.

[0029] The embodiment according to figure 3 differs firstly from the embodiment according to figure 2 in that the front chamber wall 13 has a greater distance to the front chamber wall 12. In the embodiment according to figure 3 it is provided additionally, between the front chamber walls 12, 13, an intermediate rib 15 that extends parallel to the front walls 12, 13. Therefore, in the embodiment according to Figure 3, the channel of

Fixation 8 is subdivided into two hollow fixing chambers 14. There is also the possibility that there are two intermediate ribs 15 of this type between the front chamber walls 12, 13.

[0030] The embodiment according to figure 4 differs from the embodiment according to figure 1 in that, between the front chamber walls 12, 13, there are provided three intermediate ribs 15 extending parallel to these front walls 12, 13. By Therefore, here there are four hollow fixing chambers in total 14. The wall thicknesses of the intermediate ribs 15 according to Figure 4 are smaller than those of the front walls 12, 13.

[0031] The chamber side walls 10, 11 may also have different thicknesses.

[0032] The intermediate rib 15 or the intermediate ribs 15 prevent the chamber side walls 10, 11 from separating when the fixing bolt 4 is introduced, although the chamber front walls 12, 13 have a great separation from each other or although chamber side walls 10, 11 are flexible by virtue of their thickness and / or their material.

[0033] The embodiment according to figure 5 differs from the embodiment according to figure 1 in that, in the embodiment according to figure 5, the chamber side walls 10, 11 are extruded in different materials. The left chamber side wall 10, in Figure 5, is of a different material than the right chamber side wall 11 and the front chamber walls 12, 13. The chamber side wall 10 can be made for example of a material 15 softer than the walls 11 to 13, so that the peripheral profiling of the fixing bolt 4 is further inserted into the chamber side wall 10 and essentially rests on the opposite chamber side wall 11.

[0034] The embodiment according to figure 6 differs from the embodiment according to figure 1 by reinforcement profiles 16 on the inner sides of the side walls 10, 11 oriented towards the inside of the fixing channel 8. In the embodiment according to the 6, the distance A between the side walls of the chamber 10, 11 is defined by the distance between the reinforcement profiles 16 opposite each other. The reinforcement profiles 16 can also be provided only in one of the two chamber side walls 10, 11. In this embodiment, the peripheral profiling of the fixing bolt 4, that is, in the example shown in Figure 6, the thread 6, it is introduced in the reinforcement profiles 16, which thereby undergo a plastic deformation. Since the reinforcement profiles 16 have space for the plastic deformation along the longitudinal axis 9 of the channel, the force exerted on the side walls 25 of the chamber 10, 11 in a direction perpendicular to the longitudinal axis 9 of the channel after inserting the bolt of fixing 4, is smaller than in the embodiment according to figure 1. Therefore, in the embodiment according to figure 6, it is possible to work with thicknesses of the side walls of chamber 10, 11 smaller than in the embodiment according to figure 1, without that the side walls of the chamber 10, 11 are pushed too hard outwards after inserting the fixing bolt 4. 30

[0035] The embodiment according to Figure 7 differs from the embodiment according to Figure 1 in that the chamber side walls 10, 11 are curved into the fixing channel 8. Therefore, the side walls 10, 11 constitute delimiting surfaces of the concave fixing channel 8 towards the outside. The distance A between the side walls of the chamber 10, 11 is defined by its smaller distance, approximately in the center between the front walls of the chamber 12, 13. 35

[0036] This distance A is again smaller than the outer diameter Da of the fixing bolt 4. By means of the arcuate shape of the chamber side walls 10, 11 a pre-tension of the chamber side walls 10, 11 is achieved against the displacement force that the fixing bolt 4 introduced exerts on the side walls of the chamber 10, 11 towards the outside.

[0037] In an embodiment not shown, the fixing channel 8 can be part of an additional separate fixing element 40 inserted in a corresponding hollow chamber of the hollow chamber profile 1. The fixing channel 8 predefined by the additional element it can be configured as described and shown above in relation to figures 1 to 7.

[0038] The conditioning details of the above-described configurations of the fixing zone 2 can also be combined with each other. Thus, it is possible, for example, to provide the configuration according to figure 6 additionally with 45 intermediate ribs 15. Another example of embodiment is obtained if the embodiment according to figure 7 is additionally provided with reinforcement profiles 16 according to figure 6. It is also possible other combinations of details of this type.
