Technical Field

The invention relates to a profile assembly for manufacturing a frame.

Background

With particular reference, but not exclusive, to the construction industry, the use of known profiled elements for making frames is intended to close openings, such as or windows in buildings.

Typically, profile assemblies are made by extrusion of metal, plastic or similar materials, which enable the manufacture of profiled components of different cross-sections and sizes, depending on the die used.

The profile assemblies produced using this method must be shaped, cut and finally welded to each other to produce frames of different shapes, either removable (e.g., hinges for windows) or fixed (e.g., stably fixed to walls).

Typically, denier profile assemblies are welded to each other, obtaining a perimeter of the frame, which can be made of an inner plate, such as glass or Plexiglas, to mount the window or other material suitable for actively closing the opening.

More specifically, the inner panel is mounted to the previously welded trim interior by an operator.

Then, operators locked the inner panel with the holding plate or glazing bead, with the decorative profile coupled and against the inner panel.

When fixing the glazing beads, the operator also places a sealing strip between the inner panel and the glazing bead.

After the operation is finished, the glazing beads serve as the inside of the frame and the sealing strip is pressed onto the inner panel to ensure the tightness.

However, the operation of mounting the inner plate to the outer periphery presents considerable drawbacks due to its complexity and expense.

Patent document WO2017072660 shows a manufacturing frame and framing method, which can overcome these problems.

Patent document WO2017072660 shows a method in which each profile assembly has a substantially C-shaped cross section and comprises a housing seat, inside which the inner plate is mounted.

More specifically, the profile assemblies prepared in this way are welded to one another when the respective outer skin is seated on the inner panelling for the complete framing without the need for retaining plates or glazing beads

Furthermore, the housing seat of the profile assembly is fitted with a seal adapted to abut the inner plate and prevent mutual rubbing of the inner plate and the profile assembly wall.

The seal keeps the mutual locking between the inner plate and the profile assembly stable and prevents the frame from increasing dirt, such as liquid and dust.

In fact, the moisture that penetrates into the gaps between the inner panel and the profile assembly can lead to the proliferation of moulds and bacteria, which can cause allergies and/or diseases, while having a very ugly appearance.

Generally, the known profile assemblies have imperfections due to the high temperatures reached by the material during extrusion, so that the housing seat of said profile assembly is not normally perfectly fitted around the inner plate.

For this reason, the side walls of the housing seat of the profile assembly shown in patent document WO2017072660 are substantially mutually inclined to ensure that the seal can be strongly conformed to the face of the inner panel after it has been inserted inside the profile assembly.

However, this type of profile assembly is sensitive to the mechanical structure of which the seal is glued to the inner plate.

In fact, in order to be able to insert the inner plate inside the profile assembly, the side walls of the housing seat must be inconveniently divergent.

This operation does not operate easily and must be performed on all the profile assemblies used to prepare the frame, which results in an increase in the costs of placement and installation, which inevitably affects the selling price and has the risk of making the product couple more difficult to attract the user.

Further, the seal is generally radiused and formed series of support steps to collect dirt that contacts along the inner panel and profile assembly sidewalls.

Detailed Description

With reference to the specific figures, the reference numeral 1 generally designates a profile assembly for producing a frame.

The profile assembly 1 comprises:

-at least profile elements 2 comprising at least longitudinal lanes 3 adapted to contain at least partly substantially plate-shaped plates 4 and to define at least partly around said longitudinal lanes 3 coupling plates 5 for inserting said plates 4 into said profile elements 2;

at least sealing elements 6 suitable for sealably sealing the longitudinal lanes 3, associated with the profile elements 2 by connecting means 7 and comprising at least a th corner 8 suitable for sealably fitting to the panel 4.

Within the scope of this patent document, the term "longitudinal" relating to a profile element 2 indicates the direction in which the length of the profile element 2 extends, since this profile element 2 is usually produced by an extrusion process of plastic material, the longitudinal direction therefore corresponds to the extrusion direction .

The profile element 2 is made of, for example, PVC, but heat-sealable plastics other than PVC are not excluded.

Alternatively, the profile element 2 is made of a metallic material, such as aluminum.

However, alternative embodiments are not excluded in which the piece of timber 2 is made partly of plastic and partly of a different material, in a manner similar to a material of some kind of the known type, for example it has a casing with an outer covering or inner core made of metal, wood or similar material.

Profile piece 2, comprising at least pairs of bottom longitudinal portions 9 and of side longitudinal portions 10 mutually arranged in a substantially "C" shape, having pairs of side longitudinal portions 10 extending from said bottom longitudinal portions 9 and together defining said longitudinal lanes 3.

Each lateral longitudinal portion 10 comprises an inner face 11 facing towards the inside of said longitudinal tract 3 and an outer face 12 facing towards the outside of said longitudinal tract 3 and substantially opposite to the inner face 11.

Advantageously, said profiled element 2 comprises two identical sealing elements 6, each associated with a corresponding inner face 11 of a lateral longitudinal portion 10 and arranged substantially opposite each other in a longitudinal tract 13.

In the memo of this patent text, reference is made to seals 6 and side longitudinal portions 10 without distinction, or to two seals 6 and two side longitudinal portions 10.

In fact, all the seals 6 and all the side longitudinal portions 10 that are described and shown as seals 6 and side longitudinal portions 10 consider the profile element 1 to be present.

With reference to the embodiment shown in fig. 1-3, the bottom longitudinal portions 9 and are formed integrally with the side longitudinal portion 10 , for example by extrusion through a "C" shaped die directly representing the profile element 2.

In an alternative embodiment, illustrated in fig. 4, and in another aspect, the bottom longitudinal portion 9 and the side longitudinal portions 10 are separately manufactured and subsequently assembled, the bottom longitudinal portion 9 and of the side longitudinal portions 10, e.g., , are co-extruded to form a unitary, substantially L-shaped body, while the other side longitudinal portions 10 are separately extruded and associated with the extruded bottom longitudinal portion 9 (e.g., by interlocking with one another).

In both examples described above, the profile element 2 is made with a cross-section that is substantially the same shape along its entire length and substantially the same shape as the extrusion die used.

A coupling plate 5, defined as a plate substantially parallel to the lateral longitudinal portions 10 and passing through the bottom longitudinal portion 9 to define a plate along which the plate 4 is inserted into said longitudinal tract 3.

Advantageously, said plate 4 is made of glass (single or multilayer), but not excluding Plexigal or other material, and not excluding transparent and opaque material.

The panel 4 comprises at least front faces 13 and a plurality of peripheral faces 14.

Preferably, said plate 4 comprises two identical rectangular front faces 13 and which are substantially parallel and opposite each other, and four outer edge faces 14 of identical rectangles and which are arranged at 90 ° to each other and between the front faces 13 to form a flat thick plate.

In this way, portions of the plate 4 are made substantially rectangular; however, alternative embodiments are not excluded in which the plate 4 is shaped differently, for example comprising two substantially triangular front faces 13 and three edge faces 14 to make a substantially triangular plate 4.

Again, the distance between the front faces 13 of the plates 4 is substantially equal to the distance of the inner faces 11 of the lateral longitudinal portions 10 of the profiles 2 to enable the insertion of the plates 14 inside the longitudinal lanes 3.

Advantageously, said sealing element 6 is an elongated body, which extends longitudinally along the entire length of the profiled element 2.

Type profile element 2, said sealing element 6 having a cross section of substantially the same shape along its entire length.

Again, the seal 6 is made of rubber.

Said seal 6 comprises a lever edge 28 shaped to come into mutual contact with the plate 4 during the insertion of the plate 4 into the longitudinal channel 3 to displace the seal 6 between:

at least main structures, wherein the plate 4 is outside the longitudinal track 3 and the th corner 8 is moved away from the coupling plate 5, and

at least coupling structures, wherein the plate 4 is located inside the longitudinal channel 3 and the th corner 8 is close to the coupling plate 5 and pressed to be sealingly bonded to the plate 4.

In the memorandum herein, the term "edge" with reference to the seal 6 is intended to describe a flat longitudinal face having a substantially rectangular shape extending substantially along the entire length of the seal 6.

Similarly, the term "angle" with reference to the seal 6 describes the two longitudinal face connection zones of the seal 6.

More specifically, the cross-sections of any side and any corner have the shape of a straight line and a point, respectively.

Seal 6 also includes a stop edge 15 and an outer edge 16 adjacent stop edge 15 along corner 8 at .

Advantageously, the internal angle formed by the stop edge 15 and the external edge 16 is acute to form a particularly thin end portion of the seal 6 and a tip that follows angle 8 from .

Said stop edge 15 is also adjacent to a lever edge 28 defining a concavity arranged substantially opposite to the coupling plate 5 and a concavity substantially facing the coupling plate 5.

Furthermore, the inner angle formed by the stop edge 15 and the lever edge 28 is obtuse and less than 180 °.

More specifically, said lever edge 28 is located substantially inside the longitudinal tract 3, while the stop edge 15 is located substantially outside the longitudinal tract 3.

Furthermore, the sealing element 6 comprises at least second corners 17 suitable for being sealingly glued to the profiled element 2 in the coupling configuration, the second corners 17 being arranged substantially with respect to the outer edge 16 with respect to the -th corner 18 and being placed on the outer face 12 of the lateral longitudinal portion 10 of the profiled element 2.

More specifically, the seal 6 also includes an arcuate portion 18 that is positioned along the second corner 17 adjacent the outer edge 16 and substantially across the side longitudinal portion 10.

In this way, the seal 6 is placed at angle 8 from the th corner, and the second corner 17 is placed substantially outside the longitudinal channel 3.

More specifically, profiled element 2 comprises at least substantially arched-shaped outer surface portions 19, second corner 17 sliding tightly against outer surface portions 19 during the displacement of seal 6 between the main structure and the coupling structure.

The outer surface portion 19 is obtained on the outer face 12 of the lateral longitudinal portion 10 of the profiled element 2 close to the longitudinal channel 3, while the connection means 7 are obtained on the inner face 11 of the lateral longitudinal portion 10 to associate the sealing member 6 with the profiled element 2.

In the particular embodiment shown in the figures, the connecting means 7 comprise at least recesses 20 formed between at least profile elements 2 and sealing elements 6, and at least interlocking portions 21 formed between the other profile elements 2 and sealing elements 6, which interlocking fit in the recesses 20.

Advantageously, the recess 20 is obtained longitudinally along the entire length of the inner face 11 of the lateral longitudinal portion 10 and extends substantially parallel to the coupling plate 5, while the interlocking portion 21 is obtained longitudinally along the entire length of the sealing member 6 arranged substantially opposite to the lever edge 28.

In this way, the sealing element 6 is associated longitudinally into the longitudinal channel 3 along the entire length of the profiled element 2.

The seal 6 comprises at least weakened portions 22 associated with the connection means 7, said weakened portions 22 being deformed to enable the seal 6 to be displaced between the main structure and the coupling structure.

More specifically, the weakened portion 22 extends longitudinally along the entirety of the sealing member 6 and has a portion of substantially reduced size with respect to the interlocking portion 21 which interlocks within the lateral longitudinal portion 10.

In practice, the lateral longitudinal portion 10 comprises two longitudinal fastening portions, which are arranged on the inner face 11, facing the recess 20 and substantially parallel to the coupling plate 5.

More specifically, the two longitudinal securing portions face each other along to at least partially enclose the recess 20 and define an access opening 24 for insertion of the interlocking portion 21 into the recess 20.

Again, the interlocking portion 21 is substantially larger than the entrance aperture 24 and comprises an enlarged body and two longitudinal stop portions adapted to be located immediately adjacent the longitudinal fastening portion and interposed between the enlarged lifting and weakening portions 22.

In fact, the enlarged body deforms to pass through the entrance aperture 24 and place it in the recess 20, together with the longitudinal stop , in such a way as to be able to abut against the longitudinal fastening portion and secure the interlocking portion 21 in the recess 20.

As a result, as mentioned above, the weakened portion 22 is fixed through the inlet aperture 24 to enable the seal 6 to move between the main structure and the coupling structure.

Furthermore, the sealing member 6 comprises at least rotation axes a, substantially parallel to the coupling plate 5 and fixed between the lever edge 28 and the th corner 8, the rotation axes a being such as to pivot the fulcrum about which at least part of the sealing member 6 rotates between the main structure and the coupling structure.

Advantageously, the rotation axis a is longitudinally centred along the extension of the weakened portion 22, the deformation of which causes the above-mentioned rotation.

Alternatively or in combination with the interlock formed by the recess 20 and by the interlocking portion 21, the connecting means 7 comprise at least adhesive layers placed between the sealing element 6 and the profiled elements 2, advantageously the adhesive layers are applied to the inner face 11 of the lateral longitudinal portion 10 between the recess 20 and the interlocking portion 21.

Other alternative embodiments are however not excluded, in which the adhesive layer is applied directly between the weakened portion 22 of the sealing element 6 and the inner face 11 of the profiled element 2.

Furthermore, instead of an adhesive layer, the connecting means 7 comprise at least of the th projecting parts of the profile element 2 and at least of the second projecting parts of the sealing element 6, the th projecting parts and the second projecting parts being at least partly fused to one another.

In particular, the material used for preparing the projection of profile element 2 and the material of the projection of sealing element 6 are extruded onto each other by means of a coextrusion process.

The coextrusion process enables the extruded material to leave the coupled extrusion die, in such a way that the profile element 2 and the sealing element 6 are produced in the body and each retain the physical properties of the material from which they are produced.

The profile assembly 1 comprises at least dampening assemblies 29 associated with the profile elements 2 in the longitudinal channels 3 and adapted to receive and support the plates 4 in the longitudinal channels 3 in the coupling structure.

The shock-absorbing assembly 29 has a substantially crescent-shaped cross section, the longitudinal direction of which is associated with the bottom longitudinal portion 9 and extends substantially along the entire length of the profiled element 2.

Advantageously, the shock-absorbing assembly 29 is made of rubber.

The embodiment shown in fig. 1-4 operates as follows.

From the main structure, the plate 4 is close to the section bar 2 to be inserted along the coupling plate 5 into the longitudinal channel 3 with outer edge faces 14 of them, the outer edge faces 14 facing substantially parallel and opposite the bottom longitudinal portion 9.

During the entry of the plate 4 into the longitudinal channel 3, the peripheral face 14 and, more precisely, the corner adjacent to the front face 13, come into contact with the seal 6 by pressing against the corresponding lever edge 28.

The pressure exerted by the plate 4 creates a force applied to the lever edge 28 and it creates a lever mechanism of motion.

In practice, the lever edge 28 and the stop edge 15 are basically the two arms of the lever mechanism, which are caused by their fulcrum, the fulcrum 27 and in this case the rotation axis a .

In this way, plate 4 rotates about lever edge 28 about rotation axis a away from coupling plate 5.

As a result, the stop edge 15 also rotates about the axis of rotation a, but is close to the coupling plate 5 and contacts the th corner 8 with the front face 13 of the plate 4.

At the same time, the outer edge 16 is also rotated about the axis of rotation a, approaching the coupling plate 5 and pulling it to the second corner 17, causing it to slide along the outer surface portion 19 of the outer face 12.

The plate 4 is pushed into the longitudinal channel 3 until it is pressed with the outer edge surface 14 against the damping member 29.

To its position, the seal 6 is rotated, the stop edge 15 and the lever edge 28 are pressed into contact with the front face 13 of the plate 4 by the plate 4 itself and the second corner 17 is pressed into contact with the outer surface portion 19.

In this way, the longitudinal channels 3 of the profile elements 2 are hermetically sealed.

In practice, the outer edge 16 of the sealing element 6 is arranged outside the longitudinal channel 3, with its inclination starting from the th corner 8 pressing against the contact plate 4 until it reaches the second corner 17 of the press-contact profile element 2.

More specifically, prepared in this way, the connection between the plate 4, the sealing element 6 and the profiled element 2 defines an outer configuration with a substantially reduced inclination starting from the front face 13 and continuing with the outer edge 16 and ending in an outer surface portion 19.

The alternative embodiment of the profile assembly 1 shown in fig. 5 and 6 is modified by a number of modifications of the seal 6 shown in fig. 1-4, including, in particular, the removal of the second corner 17.

Furthermore, the seal shown in figures 5 and 6 comprises at least sealing portions 23 associated with the connection means 7, the sealing portions 13 being deformed to at least partially seal the longitudinal channels 13 when the seal 6 is in the coupling configuration.

The sealing portion 23 is essentially a longitudinal portion with an essentially rectangular portion which is inserted between the connecting means 7, and the parts of the sealing member 6 comprise the th corner 8, the stop surface 15, the outer face 16 and the lever surface 28.

More specifically, the sealing portion 23 comprises two pressure sides 32, which are substantially parallel and opposite to each other, and two sealing sides 31, which are substantially parallel and opposite to each other and are proximate to the pressure sides 32 to form a rectangular portion of the sealing portion 23.

Advantageously, of these pressure edges 32 are associated with the connecting means 7 and face the contact-side longitudinal portion 10.

In this manner, the sealing portion 23 is disposed within the longitudinal channel 3, with the th corner 8 disposed substantially outside of the longitudinal channel 3 and the lever edge 28 disposed substantially within the longitudinal channel 3, similar to that described for the embodiment.

In fact, in the second embodiment, the outer edge 16 and the lever edge 28 are associated with the sealing portion 23 by means of an arched longitudinal portion 33, substantially forming a corner association between the pressure edge 32 and the sealing edge 31 of the sealing portion 23.

Again, the axis of rotation a, constrained with the fulcrum 27, is arranged along the arc-shaped longitudinal portion 33 so as to be able to rotate the seal 6, due to the deformation of the material, similar to that described for the embodiment shown in fig. 1-4.

The sealing portion 23 comprises at least projections 25, the projections 25 wrapping at least partially around the profile element 2 outside the longitudinal channel 3 when the seal 6 is in the coupled configuration.

The projection 25 is essentially an extension of the body of the sealing portion 23 substantially opposite the curved longitudinal portion 33.

More specifically, the bulges 25 are substantially immediately adjacent to the sealing edge 31 facing towards the outside of the longitudinal tract 3 and extend outside the latter in contact with the profile element 2 body to cover the zone where the lateral longitudinal portions 10 of the longitudinal tract 3 and the pressure edge 32 of the sealing portion 23 join.

The operating difference of the invention illustrated in the embodiment of figures 5 and 6 is to the embodiment illustrated in figures 1 to 4, in that, under the coupling configuration, the lever edge 28 is pressed by the plate 4 against the pressure edge 32 of the sealing portion 23, which in turn presses against the lateral longitudinal portion 10 of the longitudinal channel 3.

In this way the th corner 8 seals the joint between the plate 4 and the seal 6, similarly to the embodiment shown in fig. 1-4, while the joint between the profile element 2 and the seal 6 is sealed by the sealing portion 23 the profile assembly 1 made of the embodiment described can be prepared according to the method shown in patent document WO2017072669 in order to make the frame 30.

A frame 30, comprising:

-a plate 4; and

a plurality of profile assemblies 1.

The plate 4 is at least partly surrounded by the profile assembly 1 and has a seal 6 for coupling the profile assembly 1 in the structure.

Again, since the plate 4 is rectangular, four profile elements 1, are provided for each edge face 14, however, it will be readily appreciated that three profile elements 1 are used if the plate 4 is triangular, five profile elements 1 are used if the plate 4 is pentagonal, etc.

In practice, it is believed that the invention described achieves the intended ends.

In particular, it is to be stressed that the lever structure allows to significantly reduce the time required to surround the panel with the profile assembly.

In fact, the clamping of the longitudinal lanes with the seals occurs automatically by the operation of inserting the plates in each profile assembly.

Furthermore, the arrangement of the th corner, the second corner and the outer edge in the coupling structure makes it possible to avoid infiltration to tighten the longitudinal lanes with tightness while forming a chamfer with the plates and profile elements to prevent the formation of dirt-rich spots.

Furthermore, the operation of the frame production is simplified without requiring additional steps, such as bifurcating the profile element walls or fixing the plates to the profile elements with glass beads.
