Point holder

The invention relates to a point holder for a perforated laminated safety glass panel, with a plate on one side and a plate on the other side of the panel and a pin connecting the plates and piercing the panel hole, the point holder having a device on one side for its mounting on a supporting structure.

Laminated safety glass panels are frequently used in building construction for glass facades, glass roofs and canopies, parapets and ceilings. To date, they have been purely a structural component without any other function. However, it would be desirable to use the glass surfaces offered by such glass facades, parapets and roofs, for example for lighting, illuminated advertising or for information purposes. It is known to apply a very thin layer of an electrically conductive material, such as a metal or metal oxide or an electrically conductive plastic, to a glass panel. This completely transparent glass panel material with the conductive layer is known from WO 99/03111.

The invention is based on the object of providing a point holder

for laminated safety glass (CVSO) panels, which can also hold a conductor layer panel, so that the panel assembly created in this way can also fulfil the optical functions mentioned above. In particular, the point holder should enable the conductor layer panel to be held without drilling through it like the point-held laminated safety glass panel. Further advantages emerge from the following description.

This object is achieved according to the invention in the point holder mentioned at the beginning in that the point holder has an attached or integrated clamping part for a conductor layer plate on one side of the plate and a conductor channel for the power supply of this plate is led through the assembly device into the clamping part. With the help of these point holders, the laminated safety glass plate can be combined with a conductor layer plate, with the laminated safety glass plate taking on the mechanical function and the conductor layer plate the optical function of this plate assembly. The power supply of the conductor layer plate takes place from the supporting structure through the assembly device and the clamping part. The type of power connection to the thin conductor layer is the subject of a separate utility model application. Since the clamping part clamps the conductor layer plate around the edge of the plate, the conductor layer plate is somewhat smaller than the point-held laminated safety glass plate of the assembly. In the sense of this invention, the clamping part is integrated into the point holder if at least one component, in particular one of its plates, is also part of the clamping part.

In a preferred embodiment of the point holder according to the invention, the clamping part is screwed to the point holder as a separate holder and the circuit board is clamped between the two clamping jaws of the clamping part.

In another embodiment, a plate of the point

holder is also a clamping jaw of the clamping part. This results in a reduced height of the point holder compared to the previously mentioned embodiment with a screwed-on clamping part.

In a third embodiment of the point holder according to the invention, the circuit board is clamped between a plate of the point holder and the laminated safety glass plate. In this case, both clamping jaws are omitted; the clamping part is completely integrated into the point holder. The overall height of the point holder is thereby reduced even further.

According to the preferred embodiment of the point holder according to the invention, the clamping part contains a connection chamber which is connected to the conductor channel and the space between the clamping jaws by means of holes. On the one hand, the power cable guided through the conductor channel and on the other hand, the connection cable coming from the printed circuit board are guided into the connection chamber. Both cables are connected in the chamber by plugs. The connection chamber simplifies the assembly and electrical connection of the printed circuit board. The plug in the chamber is expediently sealed against the outside environment in a moisture-tight manner. For this purpose, the connection chamber can be sealed against the outside environment by means of a cover. Alternatively, the connection chamber can also be sealed with the

The outside of the holder must be connected by a hole through which the chamber can be filled with a plastic.

In general, the clamping part is arranged on the side of the point holder facing away from the mounting device. The conductor channel for the power supply cable then leads through the point holder, in particular axially through its pin into the clamping part, in particular up to the transverse bores to the connection chamber or to the space between the clamping jaws.

In another embodiment of the point holder according to the invention, its clamping part and the mounting device are arranged on the same side of the point holder. This embodiment is generally less preferred because the circuit board is less easily accessible, e.g. for maintenance and repair.

In a further embodiment of the point holder according to the invention, the clamping part is attached to the point holder via a spacer component. While the laminated safety glass panel and the conductor layer panel generally run parallel to one another, both can be inclined towards one another when spacer components of different heights are used. This means that, for example, in the case of a laminated safety glass panel inclined as a canopy, the conductor layer panel can run horizontally or at an incline opposite to that of the laminated safety glass panel. The height of the spacer component can be adjustable. Different angles of inclination between the laminated safety glass panel and the conductor layer panel can therefore be achieved using the same spacer components set to different heights. This spacer component can consist of two separate cylinders with external threads and a tubular cylinder with a left/right internal thread that engages with these threads. The height of the component can be changed by screwing the tubular cylinder.

The mounting device can be designed differently depending on the function of the laminated safety glass panel. If the panel is to serve as an inclined canopy, the mounting device includes an eyelet on the point holder and a threaded pipe rod attached to it in an articulated manner. The conductor channel through the mounting device is formed by the holes in the pipe rod. On both sides of the joints, the conductor channel can be led outwards so that the cable is led around the outside of the joint. To protect the external cable part, the joint with the external cable can be surrounded by a bellows-like sleeve. It is also possible to

· t

to form the joint by two hollow half-shells clamped together axially, into which the rod holes forming the conductor channel open, so that the power cable can run within the shells through the joint thus formed.

In another embodiment of the point holder according to the invention, the mounting device can comprise a threaded tube rod which is connected to the point holder in an articulated manner. This design allows the laminated safety glass panel to be suspended with limited pivoting, for example as a facade panel. Independently of this, the clamping part can also be connected to the point holder in an articulated manner. Using these joints between the laminated safety glass panel and the conductor layer panel on one edge of the panel and the above-mentioned adjustable spacer components on the other edge of the panel, the inclination of the two panels relative to one another can be varied.

It is advisable to arrange the conductor layer of the conductor layer board on the side facing the laminated safety glass board. This protects the conductor layer from rainwater, dust separation and scratching. If necessary, the space between the two boards should be sealed at the edge.

Preferably, the point holder and/or its clamping part has elastomeric pads with linear contact with the glass plate. This means that the glass plate is held between the clamping jaws or the plates without any constraints, without an undesirably high surface pressure having to be exerted. The plate material of the conductor layer plate can be any material suitable as a carrier for the conductor layer. Preferably, this plate material is glass, so that the conductor layer plate is just as transparent as the laminated safety glass plate.

Preferably, the conductor layer plate consists of two glass panes connected, for example, by a synthetic resin layer, and at least one of the two panes has an electrical conductor layer on the inside.

The invention further extends to a glass plate assembly comprising a perforated laminated safety glass plate, in the holes of which point holders are mounted according to one of the embodiments described above, and an unperforated conductor layer plate which is held by the clamping parts of the point holders. This assembly can be pre-assembled and attached to a supporting structure, e.g. a building wall or ceiling, using the assembly devices required in each case.

The invention is described below in several embodiments with reference to the drawing.

The embodiment of the point holder shown in Figure 1 comprises a screw forming the pin 5 with a flat head with an eyelet 4, onto which an upper plate 3 and a lower plate 6 are screwed with the laminated safety glass plate 7 in between. The pin 5 and the eyelet 4 have longitudinal holes 5 and 4, respectively. The pin 5 penetrates the hole 7a ^of the laminated safety glass plate with the intermediate

Position of a glass protection bushing 8, which consists for example of polyoxymethylene. The plate 6 contains holes 6 which can be used for injecting a plastic into the space between the wall of the hole 7 and the pin 5 before the clamping part 2 is mounted. Between the laminated safety glass plate 7 and the plates 3, 6, elastomer rings 9 are arranged in a known manner for elastically dampened mounting, but not for clamping the plate 7.

The clamping part 2 is screwed to the pin 5 by means of a hexagon screw 11 with an axial through-hole 11 with an elastomer ring in between. The clamping part 2 consists of a base part 12 and a cover part 13, which is screwed to the base part 12 by two screws 14 offset laterally to the axis. A conductor layer glass plate 15 is held without constraint between the clamping jaw 12 of the base part 12 and the cover part 13 with an elastomer layer body 16 in between. On the other side, the base part 12 contains a connection chamber 17, which is sealed moisture-tight by the cover part 13. The chamber 17 is connected to the clamping space 19 between the cover part 13 and the clamping jaw 12 of the base part 12 via the opening 18 between the head of the screw 11 and the cover part 13. The conductor layer glass plate has a conductor layer on its outside (facing the plate 7); furthermore, the inner elastomer layer 16 has an electrical contact conductor 20 which, when the plate 15 is clamped, touches the contact 23 of the conductor layer 15' and has a connecting line (not shown) which is led through the opening 18 into the connection chamber 17. The power supply cable (not shown) is also led through the holes 4 ^a , 5 ^a , 11 ^a and the opening 18 into the connection chamber 17 and can be connected there to the connecting line of the contact 20 by means of a plug. This construction makes it possible to first mount the laminated safety glass plate, then screw on the clamping part 2 with the power supply cable hanging through the hole 11, mount the conductor layer glass plate and finally the power supply.

supply through the plug in the chamber 17. The connection chamber 17 is then closed by the cover 21.

In the embodiments described below, the same reference numbers are used for the same parts as in Figure 1. To the extent that these embodiments correspond to that of Figure 1, the description of Figure 1 also applies to these other embodiments.

The embodiment according to Figure 2 differs from that according to Figure 1 in that the threaded pin 5 carries a threaded bolt 22 with an axial bore 22 instead of the eye plate 4. This holder can be screwed into a tubular rod with an internal thread using the bolt 22. This embodiment is suitable for attachment to railing posts, facades, ceilings and the like.

Figure 3 shows the exploded view of the point holder according to Figure 1. It is clear that this holder can be varied in various ways. For example, the eyelet of the threaded pin 5 can be changed in shape and size. The plates 3 and 6 can have different diameters depending on the thickness of the plate 7, and the clamping part 2 can be designed for different clamping widths depending on the thickness of the plate 15.

Figure 4 shows the bottom view of the base part 12 of the clamping part 2 after removal of the cover part 13. According to _figures 4 and 5, the base part 12 has a diametrical web in which two threaded holes 14' for the screws 14 for attaching the cover part and a central recess are contained in which the support surface for the head of the screw 11 and the opening 18 between the connection chamber 17 and the clamping space 19 are formed.

In the embodiment according to Figure 6, the plate

bore 7 piercing pins 5 an H-shaped axial section,

c i^b

wherein the transverse wall 5 has an axial bore 5. The pin 5 has an external thread onto which the upper plate 3 and the lower plate 6 are screwed with the laminated safety glass plate 7 and the elastomer rings 9 in between. The hemispherical head 25 of a hinge pin is inserted into the upper half of the pin 5, wherein an elastomer ring 27 is arranged between the head 25 and the transverse wall 5. The pin 5 has an internal thread in the upper area into which a ring 28 is screwed. The ring 28 has an approximately hollow spherical bearing surface 28 for the head 25 and a frustoconical opening 28 in its upper area. The hinge pin 26, like the pin in Figure 2, is used for mounting on a supporting structure (not shown), although the plate 7 can be pivoted to a limited extent. For further details of this joint, please refer to DE 201 05 094.3. In the lower part of the pin 5, a similar swivel joint is contained, mirror-symmetrically to this joint, consisting of an approximately hemispherical head 30 formed on the end of a threaded bolt 29, an elastomer ring 31 arranged between the head 30 and the transverse wall 5 and a ring 32 screwed into an internal thread of the pin 5. The shaft of the hinge bolt 29 is screwed into an axial bore 12 of the base part 12, this connection being fixed by a lock nut 33. The second swivel joint 30-32 makes it possible to attach the conductor layer glass plate 15 not only parallel, as in Figure 2, but also inclined to the laminated safety glass plate 7 if this is desired for reasons of optimal visibility of the light information provided by the plate 15. As can be seen, the hinge pins 26 and 29 have through holes 26 and 29 respectively, which together with the hole form part of the conductor channel for the power supply of the plate. The clamping part 2 is essentially identical to that of the embodiment according to Figure 2, but differs in that it has a hole 12 leading to the connection chamber 17 for injecting a plastic

is provided for the purpose of sealing the plug connection in a watertight manner. For further information regarding clamping part 2, please refer to the relevant description in Figure 1.

Figure 7 shows a point holder similar to Figure 6, but the upper joint 25-28 has been omitted and instead the pin 5 has an eyelet 4 for suspending the plate by means of a fork joint head and tension tube rod, as in the embodiment according to Figure 1. The clamping part 2 can be designed in the same way as in Figure 6 and is not shown again in Figure 7.

Figure 8 shows the use of the point holder shown in Figure 1 in a canopy made of a laminated safety glass panel that is suspended at an angle from the wall 34 in conjunction with a parallel, electrically connectable conductive layer glass panel 15. For assembly, two brackets 35 are screwed to the wall 34, the lower one of which is shown. The eye bracket 4 of the point holder closest to the wall is articulated to a fork head bolt 36 which, like the pin 5, contains an axial bore 36 as a conductor channel. The fork head bolt 36 is screwed into the bracket 35 and fixed by a lock nut 37. The eye bracket 4 of the point holder far from the wall is articulated in a similar way to a drilled fork head bolt 38 which is screwed into a tubular rod 39 with an internal thread. The tubular rod 39 is connected to the upper bracket (not shown) again via a fork head bolt. For the power supply of the conductor layer glass plate 15, one wire is connected via the lower bracket 35 through the holes 36,4,5,11 and the opening 18 to the connecting conductor of one end of the plate 15, and the other wire is connected via the upper bracket and the holes 39,38,4,5,11 and 18 to the connecting conductor of the other end of the plate 15. In Figure 8 it is shown that these conductor wires are led around the outside of the joints, see item 40. To protect these external

The area in question can be covered by a bellows sleeve (not shown) for the line parts lying there. If the joint is designed as a hollow joint, in which, for example, the end of the bolt 38 and the tab 4 form complementary hollow shells into which the holes 38 and 4 open, and in which both hollow shells are clamped together by an axis so that they can pivot against each other, the line core can also be guided directly through the joint, protected from external influences.

Figure 9 also shows a canopy made of laminated safety glass 7 and conductor layer glass 15 attached to the wall 34. This panel assembly is again mounted on the wall by means of brackets 35, only one of which is shown, and is not suspended as in the embodiment according to Figure 8, but is supported from below so that the tubular rod 39 and the fork head bolt 36 are subjected to pressure. Unlike in the embodiment according to Figure 8, the panels 7 and 15 are not parallel to one another but are inclined at an angle of approximately 10° to one another so that the panel 7 has an inclination of 10° while the panel 15 runs approximately horizontally. This is achieved by two spacer components 41 of different heights which are inserted between the elastomer disks 10 and the clamping parts 2. As can be seen, after the plate 7 has been mounted using point holders 1 on the pipe rods 39 and pipe bolts 36, the spacer components 41 are screwed onto the pins 5 of the point holders 1 using pipe screws 42 with hexagon heads, with the elastomer rings 10 in between. The chamber of the spacer components 41 is then closed by a threaded cover 43 with a correspondingly inclined threaded hole 43. Finally, the base parts 12 of the clamping parts 2 are attached using drilled screws 11, as explained above with reference to Figure 5. After the plate 15 has been inserted, the cover parts 13 are screwed on. The horizontal conductor layer glass plate 15 can transmit light information to passers-by under the canopy according to Figure 9. However, the plate 15 can also be used to illuminate the wall

to illuminate. For this purpose, the angle between the two plates 7 and 15 can be increased beyond 10°. For the electrical supply of the plate 15, the tubular rod 39, the fork head bolt 36 and the eye plates 4 have corresponding holes 39 , 36 and 4 , respectively.

The embodiment shown in Figure 10 differs from that in Figure 6 essentially in that the pin 5 of the point holder 1 only contains a hemispherical joint on the top, while the clamping part 2 is rigidly screwed to the pin 5, analogous to the embodiment in Figures 1 and 5. The elastomer ring 10 is omitted and instead a support ring is formed on the base part 12, with which the base part 12 is supported directly on the plate 6.

Figure 11 shows a first embodiment of the point holder 1 according to the invention with an integrated clamping part 2. This embodiment differs from that according to Figure 10 in that the lower plate of the point holder and the base part of the clamping part 2 form an integral part and the contact ring 12 has been omitted. This results in greater compactness and stability compared to the embodiment according to Figure 10.

Figures 10 and 11 show the conductor layer glass plates 15 that are currently preferably used, in which the conductor layer is not arranged on an outer surface of the carrier plate as in the other embodiments, but on the inside of one of the two disks forming the plate. Accordingly, the contact ^23a is arranged on the front side of the plate. Conductor layers can also be provided on the inside of both disks, which are electrically insulated from one another by the cast resin layer connecting the disks.

Another point holder 1 with an integrated clamping part is shown in Figure 12. The base part is integrally formed on the pin 5. This eliminates the cover plate 13. For access to

The connection caramers 17 are only provided with the cover 21. In the upper part, the pin 5 has a

&Aacgr; C

hole 5 stepped widened threaded hole 5 into which a screw 44 carrying the eyelet 4 is screwed. Unlike the design according to Figure 1, the upper plate 3 is screwed onto the pin 5 from the side of the tab 4 after the plates 7,15 have been inserted. In this embodiment, the conductor layer glass plate 15 lies either - as shown - directly on the laminated safety glass plate 7 or with an interposition of a thin layer in the edge area of the plate (not shown). The hole 5 is used to lead through the connecting conductor for the conductor layer glass plate 15. This embodiment has an even further reduced height compared to that according to Figure 11, since the clamping jaw 12 of the base part has been omitted. This point holder, like the one according to Figure 1, is intended for hanging plates on a tension rod system.

The embodiment according to Figure 13 differs from that according to Figure 12 only in that the step-shaped enlarged bore

C3

5 has been omitted and instead the axial bore 5 has a threaded part at the upper end into which the threaded bolt 22 is screwed. This point holder with integrated clamping part can be screwed to posts, ceilings and the like by means of bolt 22, for example.

The embodiment shown in Figure 14 differs from that in Figure 12 in that, instead of the eyebolt 44 screwed into the pin 5, a hinge pin 26 with an approximately hemispherical head 25 is pivotally mounted in the pin 5 in the manner described for the embodiment in Figure 6. Furthermore, the connection chamber 17 is not eccentrically but centrally contained in the pin 5 or its base part and is closed by the cover 21. In this embodiment with integrated clamping part and pivotable mounting, the plates 7 and 15 also lie against one another. A locking pin 45 on the plate 3 prevents the conductor layer glass plate 15 from slipping due to insufficient clamping.

While in the previously described embodiments the conductor layer glass plate 15 is arranged on the side facing away from the mounting device 4, 22, 26, Figure 15 shows a design of the point holder 1 with an integrated clamping part 2, in which the conductor layer glass plate 15 is arranged on the side facing the threaded bolt 22 as the mounting device. The base part also forms one plate of the point holder as in the design according to Figure 11, with the clamping part 2 being screwed to the pin 5, which is formed on the plate 3, by means of a screw 46. In this embodiment, the conductor channel no longer leads through the point holder 1, which contributes to simplification.
