Description

The present invention relates to a profile rail for positioning a fastening element in a groove formed between two spaced-apart surface elements in the manufacture of a multiple glazing unit, wherein the profile rail at least a first leg portion, a second leg portion and a bridge portion for connecting the at least one first leg portion with the second leg portion and wherein the first and second leg portions are formed on the bridge portion such that the profile rail is frictionally connectable with at least one edge portion of the two surface elements, so that the at least one edge portion is received in a space formed between the first and second leg portion and the second leg portion is held in the groove formed between the two spaced-apart surface elements. The invention further relates to a method for producing a multiple glazing unit.

From the publication FR 2 222 523 A is a profiled rail for positioning a fastener in a groove formed between two spaced-apart surface elements known. The profiled rail has a first leg section, a second leg section and a bridge section for connecting the first leg section to the second leg section. The second leg portion is detachably connected to the bridge portion and has a cross-section in the Essentially U-shaped profile element. The first and second leg portions are formed on the bridge portion such that the profile rail is non-positively connectable with at least one edge portion of the two surface elements, so that the at least one edge portion is received in a space formed between the first and second leg portion and the second leg portion in the is held between the two spaced-apart surface elements formed groove.

The publication GB 948,032A describes a profiled rail, which has a first leg section, a second leg section and a bridge section, wherein this bridge section serves for connecting the at least one first leg section to the second leg section.

From the publication DE 195 47 444 A1 For example, a method for manufacturing a multiple glazing unit is known, wherein the multiple glazing unit completed by the conventional method has two surface elements which are positioned at a distance from each other and which define therebetween a gas space bounded by a circumferentially extending spacer. In this known multiple-glazing unit, a resinous ring of material extending between the spacer and each of the surface members serves to hold the spaced-apart sheet members in position. Furthermore, a fastener is embedded in the resin rim to form a means for attaching the multiple glazing unit to a support structure. In this case, the fastening element has the shape of a U-shaped profile with two leg sections connected to one another via a connecting section and is designed such that it defines an outwardly open channel which serves to receive a support element of the support structure that is complementary to the cross-sectional shape of the channel ,

For producing such a multiple glazing unit is in the document DE 195 47 444 A1 proposed to fix the fastener initially only provisionally at an edge portion of the two ultimately the multiple glazing unit forming surface elements. Subsequently, the resin ring is to be formed in the groove formed with the two spaced surface elements and the spacer, by inserting into this groove a preferably resin material such that it is provisionally fixed to the edge portion of the surface element Fastening element is enclosed by the resin material and held in this permanently hardened after curing of the resin material.

With regard to the provisional fixing of the fastening element on the one edge portion of the two surface elements is provided in the prior art, using an adhesive or a double-sided adhesive tape to attach the fastener with one of its leg portions on the respective edge portion. In the manufacture of the multiple glazing unit, this should preferably be done before the two surface elements are arranged in the opposite and spaced relationship relative to each other.

Since, prior to the arrangement of the two surface elements, the fastening element has already been adhesively bonded to the edge section of one of the two surface elements, after the two surface elements have been arranged, this fastening element lies directly adjacent to the edge section of the one surface element and within the one with the respective edge sections of the surface elements and the spacer groove.

With the known method, it is thus possible to produce a multi-glazing unit which is suitable for structural glazing technique and ready for installation. This structural glazing technique makes it possible, for example, to cover facades with structural glazing without leaving visible support profiles to the outside.

However, the method known from the prior art for producing such a multiple glazing unit has the disadvantage that in the provisional fixation of the fastener to the edge portion of a surface element a precise positioning of the fastener in the groove formed with the respective edge portions of the surface elements and the spacer relatively time and is labor intensive. In order to continuously enable a high quality of the finished multiple glazing units, however, it is particularly necessary that when provisionally fixing the fastener to the edge portion of a surface element, the free ends of the leg portions of the fastener as flush as possible flush with the respective edges of the two surface elements, and before In particular, do not exceed the level of the respective edges of the surface elements. Otherwise, there is a risk that in the finished multiple glazing unit, the fastener can not absorb the carrier element of the support structure in an optimal manner.

In order to achieve the required positioning accuracy of the fastening element in the groove formed between the two spaced surface elements, it is necessary in the known from the prior art method for producing a multiple glazing unit, in a controlled manner first the tape or the adhesive to the edge portion of the surface element or on the leg portion of the formed in the form of a cross-sectionally U-shaped profile fastener. Subsequently, the fastener must be positioned and pressed as accurately as possible on the edge portion of the surface element. These steps required both for positioning the fastener in the groove formed between the two spaced surface elements and for provisionally fixing the fastener to the edge portion of the surface element should be performed and controlled by skilled workers, as a result of which the manufacturing process of the multiple glazing unit is not only relatively time consuming - but also labor intensive.

On the other hand, it is in the known from the prior art method, or only with great effort possible to position the fastener subsequently in the formed between the two spaced surface elements and the spacer groove, i. after the two surface elements have been arranged in their opposite and spaced relationship. Also, it is not possible to provisionally fix the fastening element in the groove such that the fastening element does not directly adjoin an edge section of one of the two surface elements.

Therefore, the method known from the prior art is not suitable for producing multiple glazing units in which the fastening element is to be arranged, for example, centrally between the two spaced-apart area elements.

On the basis of the problem described above, the present invention is therefore based on the primary object of specifying a method for producing a multiple glazing unit, in which before or after the introduction of a filling material, in particular a resin or silicone material, takes place in order to form a material ring formed the two surface elements groove, the fastener in the groove formed between the two surface elements much easier positioned and can be provisionally fixed without the required positioning accuracy of the fastener is deteriorated in the groove. In particular, an easy-to-implement method for producing a multiple glazing unit is to be specified, in which multiple glazing units of consistently good quality can be produced with a reduced number of work steps.

This object is achieved in that in the manufacture of the multiple glazing unit, a rail of the type mentioned is used, wherein the second leg portion has a cross-sectionally substantially U-shaped profile element, which in the installed position in the groove formed between two spaced surface elements serves as a fastening element for fastening the multiple glazing unit to a support structure, and wherein the cross-sectionally substantially U-shaped profile element is integrally connected to the rail and provided with a predetermined breaking point.

The advantages that can be achieved with the use of the profile rail in the production of a multiple glazing unit are, in particular, that with the profile rail, the fastening element can be optimally optimally positioned in the groove formed between the respective edge sections of the two spaced-apart surface elements in a particularly easy and error-free manner. Due to the fact that the profile rail can be frictionally connected to at least one of the two edge sections of the surface elements, adhesive bonding of the fastening element to the edge section of one of the two surface elements can be completely dispensed with. Rather, in the proposed solution, a profile rail is used, which is attached, for example, like a clamp on the edge portion of one of the two surface elements. In this case, this terminal is designed such that the rail is frictionally engaged with at least one edge portion of the two surface elements in a frictional engagement and holds the cross-sectionally substantially U-shaped profile element of the second leg portion in a predetermined position within the groove between the two spaced surface elements.

With regard to the method for producing a multiple glazing unit, it is provided in detail that the profile rail is first provided with the at least one first leg section, the second leg section and the bridge section connecting the first and second leg sections and two preferably glass-like planar elements. Subsequently, the two surface elements are arranged in an opposing and spaced-apart relationship, wherein the distance between the surface elements is defined by a spacer arranged between the surface elements, and wherein the two surface elements are arranged such that on the one hand between the spaced surface elements and the spacer, a gas space is included, and on the other hand with the respective edge portions of the surface elements and the spacer an at least partially circumferentially extending groove is formed. Thereafter, a material ring is formed in the groove, by a filler material, in particular a resin or silicone material, is introduced into the groove.

In the method, it is provided that either before or after the step of forming the material ring in the groove, the profile rail is plugged onto the groove formed with the respective edge portions of the surface elements and the spacer such that at least one edge portion of the two surface elements in a between the received first and the second leg portion of the rail formed space and the second leg portion of the rail is held in the groove formed between the two spaced surface elements. Finally, the connection between the second leg portion and the bridge portion of the rail is separated to obtain the multiple glazing unit with the fastener held in the material collar.

If, in the method according to the invention, the method step of plugging the profile rail onto the groove takes place before the method step of forming the material ring in the groove, it is preferred that in the method step of forming the material ring in the groove, the filling material is introduced into the groove such that the second leg portion of the rail is at least partially enclosed by the filler material.

If, on the other hand, in the method according to the invention the step of attaching the profiled rail to the groove takes place after the step of forming the material ring in the groove, it is preferred that the profiled rail is fitted onto the groove in such a way that the second leg section of the profiled rail differs from that in FIG the groove introduced filling material is at least partially enclosed.

In a preferred realization of the method according to the invention, a preferably room temperature curable resin material or a preferably room temperature polymerizable silicone material is used to form a ring of material in the groove as filler material. The silicone material should advantageously be a material which is at least partially permanently elastic in the polymerized state. Of course, other materials come into question here.

Thus, it is provided in a particularly preferred realization that the first and second leg portions of the rail are formed on the bridge portion of the rail so that the rail is plugged over at least one of the two edge portions of the surface elements. In particular, it is conceivable that the first and second leg portions are formed on the bridge portion such that the profile rail can be plugged over at least one edge portion of the two surface elements, so that the at least one edge portion in the intermediate space formed between the first and the second leg portion form fit taken and the rail in the groove between the two spaced surface elements of the multiple glazing unit is positively and positively held.

This non-positive and positive holding the second leg portion of the rail in the groove between the two spaced surface elements of the multiple glazing unit is preferably achieved in that at least one of the first leg portion has at least one substantially perpendicular to the bridge portion extending side web, wherein the distance between the side web of the first leg portion and the first leg portion side facing the cross-sectionally substantially U-shaped profile element of the second leg portion is substantially identical to the thickness of that edge portion of the surface element which is received in the intermediate space formed between the first and second leg portion, when the rail is inserted over the edge portion of the surface element.

Alternatively or additionally, however, it is also conceivable that at least one first leg section has at least one side web extending substantially perpendicular to the bridge section with at least one holding web projecting from the side web towards the second leg section, wherein the distance between the at least one side web of the first leg section and the side facing the first leg portion of the profile element of the second leg portion formed in a substantially U-shaped section is greater than the thickness of that edge portion of the surface element which is received in the space formed between the first and second leg portion, when the rail over the edge portion of Surface portion is inserted, wherein the at least one of the side web projecting retaining web is formed such that it, when the rail is inserted over the edge portion of the surface element, a n the side facing the first leg portion that surface element abuts, the edge portion is received in the intermediate space formed between the first and the second leg portion.

In a particularly preferred realization of the at least one holding web projecting from the side web of the first leg section, it is provided that this holding web is designed as a resilient, preferably sheet-shaped element, in the direction of the associated side web. However, it would also be conceivable as an alternative or in addition to this that the at least one holding web projecting from the at least one side web of the first leg section is formed of a flexible material and has a soft consistency compared to the material of the side web.

In order to ensure that the fastening element can not only be positioned directly adjacent to the edge section of one of the two planar elements, in a preferred development of the profile rail used in the manufacture of the multiple glazing unit, it is provided that the profile rail comprises a total of two first leg sections which are in such a way the bridge portion are connected, that the second leg portion between the two first leg portions is arranged, and that in each case between one of the first leg portions and the second leg portion, a gap is formed, wherein the two first leg portions are formed such that the rail over both edge portions of Plane elements can be plugged, so that the respective edge portions of the two surface elements are accommodated in each one of the spaces formed with the leg portions and the second leg portion in the groove is held between the two spaced surface elements.

Basically, with regard to the profile rail that the second leg portion is connected via a predetermined breaking point with the bridge portion, which can be achieved that after forming the material ring in between the two spaced-apart surface elements formed groove, and preferably after the (at least partially) curing or polymerizing the filling material used to form the material ring, the second leg portion can be separated from the rail or from the bridge portion.

It is preferably provided that the bridge portion of the rail in cross-section is at least as long as the distance between the surface elements. This measure facilitates the introduction of the filling material into the groove in order to form the material ring.

With regard to the cross-sectionally substantially U-shaped profile element of the second leg portion is preferably provided that this profile element has two substantially perpendicular to the bridge portion extending side webs, which are connected to a connecting portion with each other, wherein the connecting portion is preferably inclined in such a manner in that the side land, which is adjacent to the surface element received in the space between the first and second leg portions of the rail, is longer than the other side land. The angle of inclination may be more than 10 °, for example between 10 ° and 45 °, preferably between 25 ° and 40 °, and most preferably 35 °.

Preferably, the cross-sectionally substantially U-shaped profile element of the second leg portion is further designed such that it has a width which is less than half the distance between the first and the second surface element, whereby sufficient space between the fastening element and the respective surface element is created for introducing the filler.

Furthermore, the fastening element should preferably have a depth which is approximately between 25% and 75% of the depth of the space to be occupied by the filling material. In this case, the depth of the space to be occupied or occupied by the filling material corresponds to the distance of the spacer from the respective edges of the surface elements. This ensures that the filler material communicates with a sufficient area of the respective surface elements to provide a reliable frictional connection therewith, while at the same time the substantially U-shaped profile element has sufficient depth to provide secure attachment of the finished during use To ensure multiple glazing unit.

Moreover, it is conceivable to provide a plurality of U-shaped profile elements which extend together around the multiple glazing unit. Preferably, a number of fasteners are provided which together extend substantially completely around the perimeter of the multiple glazing unit. This has the advantage of providing the best attachment of the multiple glazing unit to the support structure. For example, if the multi-glazing unit has a generally rectangular shape, four fasteners are preferably provided, each extending along a respective edge of the multi-glazing unit with the fasteners at right angles to one another. Alternatively, fasteners may be provided only on two, for example, facing away from each other edges of the multiple glazing unit.

The profile rail is preferably formed of a plastic material, in particular a PVC material in one piece.

In order to provide the greatest strength of the arrangement of spacers, surface elements and fastening elements, the material ring preferably extends at least between the spacer and each of the surface elements.

Preferably, the filler is preferably a room temperature curable resin material or a preferably room temperature polymerizable silicone material. The silicone material should advantageously be a material which is at least partially permanently elastic in the polymerized state. Of course, other materials come into question here.

With reference to Fig. 1A to Fig. 1C In the following, a first preferred embodiment of a profile rail 1 for positioning a fastening element 21 in a groove formed between two spaced apart surface elements will be described in the production of a multiple glazing unit.

As shown, the profiled rail 1 according to the first preferred embodiment has a first leg section 10, a second leg section 20 and a bridge section 30, 31 for connecting the first leg section 10 to the second leg section 20. It is provided that the first leg portion 10 has two substantially mutually parallel side webs 11 each having a protruding from the associated side web 11 retaining web 12. The holding webs 12 are each designed as a resilient in the direction of the side web 11, sheet-shaped element. At the respective free ends of the holding webs 12, an abutment element 13 is provided in the form of a substantially perpendicular to the bridge section 30, 31 extending side surface. At this stop element 13 abuts the edge portion of a surface element, when the rail 1 is inserted over the edge portion of a surface element.

The second leg section 20 is detachably connected to the bridge section 30, 31 and has a profile element 21 which is essentially U-shaped in cross-section and which forms the fastening element when the profile rail is used to produce a multiple glazing unit. As in FIGS. 7A and 7B In this case, the fastening element 21 determines a channel, which is open towards the outside with regard to the multiple glazing unit 100, and which is designed to accommodate a support element, not explicitly shown, of a support structure.

evidenced Fig. 1A to Fig. 1C In particular, the fastening element 21 has a shape of a U-shaped profile with two side bars 22a and 22b, which are interconnected with a connecting portion 23, which is preferably inclined at an angle of approximately 35 °. It can thus be achieved that in the finished multiple glazing unit 100, for example according to FIGS. 7A and 7B in that the filling material 106 can completely fill the space N between the spacer 105 and the surface elements 101, 102.

The releasable connection of the second leg portion 20 with the bridge portion 30, 31 via a predetermined breaking point K, which is designed for example as a notch at the transition between the second leg portion 20 and the bridge portion 30, 31. This connection between the bridge portion 30, 31 and the second leg portion 20 serves to easily separate the second leg portion 20 from the bridge portion 30, 31 without damage to the second leg portion 20 when the second leg portion 20 is substantially separated U-shaped profile element 21 in the manufacture of a multiple glazing unit 100 in the groove N formed between two spaced-apart surface elements 101, 102 is held with a filler 106.

Specifically, at the in Fig. 1A to Fig. 1C shown embodiment, the predetermined breaking point K between the second leg portion 20 and the bridge portion 30, 31 at the end of a step 31 of the bridge portion 30, 31 provided such that the second leg portion 20 with the cross-sectionally substantially U-shaped profile element 21 of a in Fig. 1A shown first position in an in Fig. 1C shown second position (and vice versa) is pivotable, wherein the pivot point in this pivotal movement at the junction K between the bridge portion 30, 31 and the second leg portion 20 is located.

In the in Fig. 1C shown second position, the second leg portion 20 is substantially perpendicular to the bridge portion 30, 31, whereas in the in Fig. 1A shown at least one side webs 22b of the cross-sectionally U-shaped profile of the fastener 21 is substantially in the plane of the bridge portion 30, 31.

To the second leg portion 20 with the cross-sectionally substantially U-shaped profile element 21 in the in Fig. 1C To hold shown second position, a latching mechanism 24, 32 is provided, which has a first locking member 24 at the free end of the side bar 22a and a complementary thereto formed second locking member 32 on the bridge section 30, 31. The two locking members 24, 32 are - as in Fig. 1B shown - in a preferably releasable (positive engagement) engageable, when the second leg portion 20 is substantially perpendicular to the bridge portion 30, 31.

In detail, the bridge section 30, 31 has a first section 30 and a second section 31 which is step-shaped with respect to the plane in which the first section 30 lies. At the in Fig. 1C illustrated state of the second leg portion 20 of the first embodiment of the rail 1, the step-shaped second portion 31 of the bridge portion 30, 31 forms a cover for the cross-sectionally substantially U-shaped profile element 21, so that between the side bars 22 a, 22 b and the Connecting portion 23 lying open channel of the substantially U-shaped profile element 21 is then covered accordingly. This cover formed with the second portion 31 of the bridge portion 30, 31 prevents filling material 106 from entering the space trapped between the side bars 22a, 22b and the connecting portion 23 when the rail 1 is used in manufacturing a multiple glazing unit 100.

By forming the second section 31 of the bridge section 30, 31 in a step-shaped manner, it is possible to set the depth with which, in the production of a multiple glazing unit 100, the profile element 21 of the second leg section 20, which is essentially U-shaped in cross-section, in FIG is held between the two spaced-apart surface elements 101, 102 of the multiple glazing unit 100 groove formed when the rail 1 with at least one edge portion 101 ', 102' of the two surface elements 101, 102 is non-positively connected, so that the at least one edge portion 101 ', 102 'in a gap formed between the first and the second leg portion 10, 20 P is received and the second leg portion 20 is held in the groove N formed between the two spaced-apart surface elements 101, 102. It can be seen that the stronger the step shape of the second section 31 of the bridge section 30, 31 with respect to the first section 30 of the bridge section 30, 31 is formed, the deeper is the cross-sectionally substantially U-shaped profile element 21 of the second leg section 20 can be positioned in the groove N formed between the two spaced-apart surface elements 101, 102 of the multiple glazing unit 100.

The details of the rail 1 according to the first embodiment will be described below in connection with Fig. 5 to Fig. 7 described. It can be seen from these figures how a multiple glazing unit 100 can be produced with the aid of the profiled rail 1.

In detail, the synopsis shows the FIGS. 1 and 5 to 7 in that in the profile rail 1 according to Fig. 1C the first and second leg sections 10, 20 are formed on the bridge section 30, 31 in such a way that the profile rail 1 can be frictionally connected to at least one edge section 101 ', 102' of the two surface elements 101, 102 forming the multiple glazing unit 100, so that the at least one an edge portion 101 ', 102' is received in the space P formed between the first and second leg portions 10, 20, and the second leg portion 20 is held in the groove N formed between the two spaced-apart surface members 101, 102.

The holding of the second leg portion 20 in the groove N formed between the two spaced-apart surface elements 101, 102 is used in the manufacture of the multi-glazing unit 100 to position the cross-sectionally substantially U-shaped profile element 21 of the second leg portion 20 in the groove N and provisionally fix before the groove N is filled with the filler 106.

In accordance with the invention, the first and second leg sections 10, 20 of the profiled rail 1 are formed on the bridge section 30 of the profiled rail 1 in such a way that - as in particular in FIG FIGS. 5A and 5B shown in the manufacture of the multiple glazing unit 100, the rail 1 over at least one edge portion 101 ', 102' of the two surface elements 101, 102 can be plugged, wherein at least one edge portion 101 ', 102' of the two surface elements 101, 102 of the manufactured multiple glazing unit 100 in the between the first and second leg portions 10, 20 can be achieved that with the rail 1, the fastening element 21 in the formed between the respective edge portions 101 ', 102' of the two spaced-apart surface elements 101, 102 groove N are optimally positioned in a particularly easy and error-free manner can.

In the profile rails 1 shown in the drawings, at least one first leg portion 10 at least one substantially perpendicular to the bridge portion 30 extending side web 11 with at least one of the side web 11 in the direction of the second leg portion 20 projecting support web 12. This embodiment is particularly suitable when the distance L between the at least one side web 11 and the first leg portion 10 facing side of the cross-sectionally substantially U-shaped profile element 21 of the second leg portion 20 is greater than the thickness of the in between the first and second leg portion 10, 20 formed intermediate space P edge portion 101 ', 102' of the surface element 101, 102 is.

evidenced FIGS. 5A and 5B With regard to the profiled rail 1, provision is made in this connection in particular for the at least one retaining web 12 projecting from the side web 11 to be designed such that, when the profiled rail 1 is inserted over the edge section 101 'of the surface element 101, to the first leg section 10 facing side of the surface element 101 abuts, the edge portion 101 'is received in the intermediate space P formed between the first and the second leg portion 10, 20.

Alternatively, it would of course also be conceivable to design the profiled rail 1 such that at least one first leg section 10 has at least one substantially perpendicular to the bridge section 30 extending side web 11, wherein the distance L between the at least one side web 11 and the first leg portion 10 facing Side of the substantially U-shaped in cross-section profile element 21 of the second leg portion 20 is substantially identical to the thickness of the in between the first and second leg portion 10, 20 formed intermediate space P edge portion 101 ', 102' of the surface element 101, 102 is.
