Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to an attachment device for mounting a glass pane fixedly at a structure, such as a building.

The invention also relates to a facade with attachment devices for mounting glass panes fixedly to a structure, such as a building.

This invention further relates to a punctiform holder (a holder having the form of a point), or an attachment device, to connect insulating glass panels that is used to connect at least two glass plates that are separated from each other by an air gap that is preferably filled with a gaseous medium, whereby the punctiform holder is detachably or non-detachably connected to a substructure.

2. Background of the Invention

A holder of this type that can be used as a punctiform holder that is free of bending moments for multiple-pane insulating glass panels is disclosed in German Utility Model 93 18 862. In that case, the punctiform holder is penetrated by borings that are inside the separated glass plates. For this purpose it is necessary, in the vicinity of the borings inside the separated glass plates, to hermetically seal the glass plates with respect to the closed air space that surrounds them. Simultaneously, these separating devices between the two glass plates are also required to withstand or provide the force of the connection of the insulating glass plates by the punctiform holder. Thus, on the one hand, one contact plate is in contact with the outer area of the separated glass plates, and, on the other hand, another contact plate is in contact with the inner area of the separated glass plates, which are pulled toward each other by means of a screw element. In the vicinity of the connection of the punctiform holder, the holder is equipped with a ball and thus is movable within the complementary surfaces of the inner plate such that a rotation of the holder unit with respect to the substructure is possible. It is thereby possible to partly compensate for corresponding construction tolerances. Because this punctiform holder, on otherwise conventional single-pane glass panels, extends through the separated glass plates, it is very complex, expensive and critical to ensure the long-term stability of the connection. In addition to the borings that have to be introduced, it is also important to permanently and securely seal the air gap between the separated plates.

German Patent 44 00 979 A1 also discloses a similar device on which the clamp element or locating bearing on the inside of the building has, on its shell surface facing the holder, a crown-shaped surface, against which a compensating part with a complementary universal ball joint with a crown-shaped surface is in contact. The clamping element has a boring that runs all the way through the clamping element to hold the clamp bolt that connects the clamp elements, and a retaining bolt that runs through a spacer washer and the compensating part and is screwed into the clamp element. With the device of the prior art, construction tolerances between the boring in the glass panel and the substructure (holder) can be compensated, but there is no flexible elastic support of the plate on the holder after the glass plate has been installed.

German Patent 44 45 724 A1 describes a similar device in which the clamp element on the inside of the building has, on its shell surface facing the mounting, a crowned surface, with which the complementary surface of a pivot bearing of a fastening part is in contact, whereby the pivot bearing is held with some lateral play in a cap nut. Here, too, after installation, no relative movement between the plate and the fastening part is possible.

European Patent 0 784 129 A1 further describes a support of a fastening bolt on a holder on which a plate of the holder is fixed between two plano-convex lenses that are in indirect contact, via their plane surfaces, with the plate, whereby one lens is in contact with its convex surface on a clamp element on the inside of the building and the other lens is in indirect contact with a nut that receives the fastening bolt.

OBJECT OF THE INVENTION

The object of the invention is to simplify the prior art as described above to create a punctiform holder that can be manufactured economically for insulating glass panels. At the same time, the punctiform holder has a mounting that is essentially free of bending moments with a simultaneous compensation of tolerances with respect to the substructure.

Another object of the invention is to create a punctiform holder that can be manufactured economically for insulating glass panels, for example, glass panels to be utilized in a glass facade of a building.

SUMMARY OF THE INVENTION

The invention teaches that this object can be accomplished by a punctiform holder to connect insulating glass panels with at least two glass plates separated by an air gap that is preferably filled with a gaseous medium, and whereby the punctiform holder is also detachably or non-detachably connected to a substructure, characterized by the fact that the punctiform holder has a mounting element with a flat mounting surface which is detachably or non-detachably connected with an outside surface of the glass plates by adhesive and, in the air gap, in the vicinity of the punctiform holder, a spacer piece between the glass plates is also detachably or non-detachably connected with the glass plates by an adhesive. Further features of the invention are described herein.

The invention teaches that the borings that are conventionally present in the glass plates are omitted, and the detachable or non-detachable connection of the punctiform holder, which has a flat mounting surface, to one of the separated insulating glass plates, is formed by means of an adhesive. So that the weight of the insulating glass panel can also be supported securely by the punctiform holder even when there are two separated glass plates, in the air gap between the separated glass plates there is a spacer piece which is also detachably or non-detachably connected with the glass plates by an adhesive. This spacer piece can thereby be made of glass or metal. The adhesive used must be essentially UV-stable and preferably transparent. It must also have long-term creep stability with regard to the load-bearing characteristics. The proposed holder is also constructed so that it mounts the glass plates on a substructure in a manner that is free of bending moments. This concept also applies to the adhesive connection between the proposed holder and the insulating glass panel. The holder is therefore constructed so that it has an inside clamp element on its mounting surface that faces away from the glass plate in the form of a crown-shaped or curved surface formed by a permanently elastic flexible element, against which a complementary surface of an inner shell surface of a cap bell or coupling bell and a fastening bolt or attachment bolt can be placed in contact with an adjustable bias, whereby between the cap bell and the fastening bolt on one hand and the fastening bolt and the mounting on the other hand there are respective three-dimensional articulations that can be made rigid.

The invention teaches that wind pressure and thermal stresses are absorbed by the elastic support of the cap bell on the inside clamp element so that, even after installation, a relative movement of the two parts with respect to each other is possible without the introduction of restoring forces in the separated glass plates.

This capability is virtually guaranteed by the adjustable bias between the clamp element and the cap bell. As a result of the multiple subdivision of the fastening device by means of at least two additional three-dimensional articulations, not only is there an ability to compensate for rather large construction tolerances, but the individual articulation points of the three-dimensional articulations also form, even when they are rigidly clamped in place after installation, to a certain extent, junction points with a certain inherent elasticity which also contribute to the stress-free mounting of the glass plates.

In one embodiment of the invention, the inside clamp element itself can have a conical or crown-shaped surface on its shell facing away from the glass plate. Theoretically, the conical or crown-shaped surface can also be formed by the permanently elastic spring element even if the clamp element is flat. Furthermore, in the inside clamp element there can be a boring that connects the inside clamp element with the cap bell set screw, whereby, in one configuration of the invention, the permanently elastic spring element is realized in the form of a permanently elastic pad which is located between the conical or crown-shaped surface of an inside clamp element facing the mounting plate and the complementary surface of the cap bell. By means of the cap bell set screw described above, the permanently elastic pad can be biased so that not only can the stresses introduced in the glass plates be absorbed by the permanently elastic pad itself, but also a relative displacement of the cap bell, with respect to the permanently elastic pad, is possible, so that the glass plates and thus also the connection between the glass plates and the nut remain virtually completely stress-free.

One special characteristic of the invention is that the cap bell, on its side facing the holder, has a cylindrical extension that is provided with a male or external thread between which and the cap bell, in the vicinity of the bottom of the cap bell, there is an inwardly directed flange to support the bolt head of the cap bell set screw. The resulting play between the flange and a shank of the cap bell set screw thereby makes it possible to locate a washer that is realized in the form of a lens between the flange and the screw head of the cap bell set screw, so that the shank of the cap bell set screw can exert an oscillating or reciprocating movement with respect to the cap bell. This oscillating movement is facilitated if the contact surface of the flange and the matching surface of the lens are realized with a conical or crown shape. For this purpose, it has been found to be appropriate to use a non-metallic lens, for example, one that is made of a hard rubber that has a sliding capability. In this manner, an additional three-dimensional articulation can be practically created between the cap bell and the inside clamp element and thus the glass plates.

An additional three-dimensional articulation results from the fact that the end surface of the extension of the cap bell that points toward the holder can be curved in the shape of a concave lens, whereby a pot-like cap nut or union nut that is screwed over the male thread of the extension of the cap bell can have an inside bottom surface that is curved so that it is opposite to the curvature of the end surface of the extension of the cap bell. Between the end surface of the extension of the cap bell and the inside bottom surface of the cap nut, two plano-convex lenses can be mounted with their flat surfaces in contact with each other. By means of the cap nut described above, the three dimensional joint described above can be fixed in position and thus be made rigid after installation.

In one advantageous configuration of the invention, the piano-convex lens that is in contact with the inside bottom surface of the cap nut can be a component of a nut that holds the fastening screw, as a result of which it is possible to screw the fastening screw more or less deeply into the nut to shorten or lengthen the entire fastening device as necessary. To achieve the above-mentioned three-dimensional articulation, the shank of the nut can be sized so that it runs through a boring in the bottom of the cap nut with some clearance.

An additional three-dimensional articulation can be realized, in the manner of the prior art, in the vicinity of the direct connection of the fastening screw with the holder if the fastening screw runs through a boring in the holder with some clearance and the holder is fastened between a nut and a locknut, whereby, between the nut and the locknut on one hand and the structure on the other hand, there are respective plano-convex lenses with their respective flat surfaces in contact with the structure, and the nut and locknut have contact surfaces that are complementary to the lens. To further explain, one plano-convex lens can be positioned between a nut and a substructure and a second plano-convex lens can be positioned between a locknut and a substructure. In this case, too, it is a question of an adjustable and adaptable three-dimensional articulation during installation that can be made rigid and fixed into position after the installation has been completed, whereby a spacer sleeve can be provided between the three-dimensional articulation that forms the connection to the structure and the three-dimensional articulation that is formed by the cap bell and the cap nut.

DESCRIPTION OF THE PREFERRED EMBODIMENT

A punctiform holder 1 as shown in FIG. 1 has a mounting element 5 with a flat mounting surface 4 which is glued, using an adhesive, to the insulating glass panel that comprises at least two individual glass plates 2 , 50 . The glass plates 2 , 50 are separated on their surrounding edge in the conventional manner by a spacer 54 , so that, between the glass plates 2 , 50 there is an air gap 52 . This air gap 52 can be filled with a gas. The glass plates 2 , 50 can be manufactured in the form of single-pane safety glass or as laminated glass such as safety glass. In FIG. 1 , the punctiform holder 1 is detachably or non-detachably connected or attached with the flat mounting surface 4 to an outside surface of the glass plate 50 using an adhesive 51 .

In the vicinity of the punctiform holder 1 , a spacer piece 53 between the glass plates 2 , 50 is also detachably or non-detachably connected with the glass plates 2 , 50 using an adhesive 51 . Thus there can be a direct transmission of force from the glass plates 2 , 50 to the punctiform holder 1 . As is clear in the exemplary embodiment illustrated in FIG. 1 , with such a fastening of a punctiform holder 1 to the glass plates 2 , 50 using adhesive, there is no need to machine the glass, i.e. there is no need to introduce borings and to seal these borings with respect to the air gap 52 between the insulating glass plates 2 , 50 . This type of holder essentially enormously simplifies and lowers the cost of manufacturing such insulating glass panels. The adhesive used is thereby UV-stable and is preferably transparent. The spacer piece 53 used can thereby be made of glass or metal.

In the exemplary embodiment illustrated by FIG. 1A , the mounting or installation element 5 has a conical shell surface 14 facing away from the flat mounting surface 4 , against which conical shell surface 14 a permanently elastic spring element 7 that is realized in the form of a permanently elastic pad 19 supported on a projection 57 (shown in FIG. 2 ), which spring element practically forms the actual shell surface 6 of the mounting element 5 , is in contact. In contact with this shell surface 6 is an inner shell 9 of a cap bell or coupling bell 10 with a complementary surface 8 . A blind hole 16 (See FIGS. 3 and 4 ) of the mounting element 5 connects the mounting element 5 with a three-dimensional articulation 12 (shown in FIGS. 1 A and 2 ). For this purpose, the blind hole 16 has an internal or female thread 15 . Engaged in the internal thread 15 is a cap bell set screw 18 , the screw head 24 of which is supported on a flange 23 of a cylindrical extension 21 of the cap bell or coupling bell 10 (refer to FIGS. 5 and 6 ). Between the flange 23 and the screw head 24 there is a preferably elastic lens 27 (refer to FIGS. 7 & 8 ), which is supported on a contact surface 28 of the flange 23 (shown in FIG. 6 ), so that, at this point, a three-dimensional articulation ( 12 ) is formed in the context of the clearance 26 , as shown in FIG. 2 . For this purpose, the lens 27 has a complementary surface 29 (see FIGS. 6 through 8 ). FIG. 6 shows the cylindrical extension 21 of the cap bell 10 that in the vicinity of the base 22 has an end surface 30 that is directed toward a substructure 3 (shown in FIG. 2 ), whereby the end surface 30 has a concave curvature. As FIG. 12 shows, an inner bottom surface 32 of a cap nut or union nut 31 has a correspondingly opposite curvature, so that two lenses 34 and 35 , the flat surfaces 33 of which are in contact with each other, can be located between the end surface 30 of the extension 21 and a base 39 of the cap nut or union nut 31 (refer to FIG. 2 ). The lens 34 is movable and is in contact with its convex surface against the end surface 30 of the extension 21 (shown in FIG. 5 ), while the second lens 35 , as illustrated in FIGS. 9 and 10 , is a fixed component of a nut 36 that holds a fastening screw or attachment bolt 11 (shown in FIGS. 1 A and 2 ), and is supported with its convex surface on the base 39 . The nut 36 has a shank 37 (refer to FIGS. 9 and 10 ) that runs through a boring 38 in the cap nut 31 , as shown in FIGS. 11 and 12 , with clearance 40 (shown in FIG. 1 A).

FIG. 1A shows that when the cap nut 31 is screwed onto the cap bell 10 by means of a male thread 20 (shown in FIG. 6 ) in the vicinity of the extension 21 , the three-dimensional articulation, which is designated 12 in general and is formed by the two lenses 34 and 35 (refer to FIG. 2 ), can be fixed in position. The nut 36 (See FIGS. 9 and 10 ) has a blind hole 56 with an internal or female thread 55 , into which the fastening screw 11 can be screwed, whereby in the outside cylindrical surface of the nut 36 there are flats 58 for the use of a wrench. FIG. 1A also shows that in the exemplary embodiment, adjacent to the nut 36 there is a spacer sleeve 49 , which for its part is supported against a nut 43 that clamps the substructure 3 . Between the nut 43 and a locknut 44 there are lenses 46 and 47 which are in contact with complementary contact surfaces 48 of the nut 43 and the locknut 44 . Flat surfaces 45 of the lenses 46 and 47 lie in direct contact with the substructure 3 .

Because a fastening screw 11 runs through a boring 41 in the substructure 3 with clearance 42 , here again, a three-dimensional articulation designated 13 is formed, by means of which construction tolerances can be compensated.

FIG. 2 shows the possible angular position of an insulating glass panel comprising the separated glass plates 2 , 50 with respect to the substructure 3 with a corresponding setting of the three-dimensional articulations 12 and 13 , as well as a corresponding angled position in the vicinity of a shank 25 of the cap bell set screw 18 with respect to the cap bell 10 on one hand and with respect to the cap nut 31 on the other hand. It is apparent that a displacement of the cap bell 10 with respect to a permanently elastic spring element 7 has taken place. In other words, at this point a three-dimensional articulation has been formed that cannot be permanently fixed in position. The permanently elastic spring element 7 has not changed its position relative to the mounting element 5 as a result of the support on the projections 57 .

FIG. 13 shows a perspective view of a building B with a glass facade F composed of glass panels 200 and indicates the attachment of a punctiform holder 1 .

FIG. 14 shows an elevation of part of a building facade F with glass panels 200 and indicates where a punctiform holder 1 would attach to the glass panel 200 .

The fastening device described above can therefore be used to retain the elasticity of the glass plates 2 , 50 because it does not restrict their freedom of movement and thus leads to a neutralization of forces. The fastening device claimed by the invention makes possible an adaptation to environmental constraints and does not lead to the rigidity of the construction material glass, which would necessarily lead to the destruction of the glass, as is the case in the prior art described above.
