EP1066445B1 - Transparent building element with triangular ribs - Google Patents

Abstract

A transparent building element, in particular made of glass, takes for example the shape of a glass pane (39, 40, 41) arranged on or in a closure element provided in or on a building, for example a door (32), a window (33) or an upper light inlet (42). In order to appropriately and economically deflect light, at least one outer or inner surface, in particular a main surface (6) of the transparent building element, has a ribbed structure composed of individual, parallel ribs (11) integrally formed with the building element (36) and having a triangular cross-section. At least one first group of these triangular side surfaces (12) formed on the ribs (11) is oriented in such a way that together they form a refraction or reflection surface for appropriately deflecting at least one partial range of the light (44) passing through the transparent building element.

Description

The invention relates to a translucent component the preamble of appended claim 1 as it is known from EP-A-0 201 920 is known. The invention also relates to a advantageous use of the same.

In the case of a conventional glass pane made of window glass, the Glass pane essentially unchanged in the light illuminating room. Most of the time it is dark Floor of the room to be illuminated, while e.g. the Worktop of a desk remains too dark. Light goes on lost through absorption on the floor, the yield is so low that an artificial light source is often switched on got to. On the other hand, it comes with a usual one through a window or a skylight often used to dazzle the room Sun. To reduce this glare, the window must go through Roller blind or awning or the like can be darkened what in turn, the light output introduced into the room is reduced. Often, such darkened rooms become paradoxical again used an artificial light source, for example the Worktop of a writing or computer desk is glare-free illuminate. It would therefore be desirable to have a targeted one Provide light control so that the lighting in the with Light to be supplied to the needs of those using the space People is more adapted.

The aforementioned EP-A-0201920 describes a glass component in the form of a multi-pane insulation unit with integrated light-directing system, with the features of the generic term of attached claim 1.

The document relates more precisely to a multi-pane insulating glass unit with at least two plane-parallel and in one Spaced glass panes and one, between this arranged, light-directing system, for example in form a prismatic plate. Between the light exit side of the Prismatic plate and the underside of the adjacent glass pane a light-scattering agent is provided, which consist in it can that the surface of the specially processed adjacent glass pane, for example is etched or sandblasted.

Next is, for example, from the high-rise building of the German Patent Office, Zweibrückenstrasse, Munich known a glass pane, which is in a door located, which connects a first hallway with a room and at one point is arranged where a second hall branches at right angles, like this for example, shown in FIG. 16. A person 238 who is along the second corridors 232 moved to the door 233, can not see whether a Obstacle behind that formed by the intersection 237 of the two corridors 231, 232 Corner is located. In particularly hectic situations, this can lead to one Collision between people 238 or vehicles 235 come.

In factory halls, therefore, are often in such places as in confusing areas Places in traffic, mirrors attached to the to facilitate the overview. In buildings with well-kept However, such a mirror is disturbing to the ambience. Furthermore are becoming more and more parts of buildings such as entire stairwells made of glass. Will be in such a glass Part of the building attached a "traffic mirror" - what already is difficult because you don't see the mirror like on normal walls can simply be dowelled, so the mirror takes light away, the mirror acts both from the inside and from the outside disruptive element. Here would be a targeted light control desirable that the clarity at confusing Places where a translucent component after the The preamble of claim 1 is arranged without using Mirroring or other optics to be attached separately Aids improved.

The object of the invention is a translucent component to further develop according to the preamble of claim 1 that targeted with simple and in particular inconspicuous means Light control can be achieved.

This task is accomplished by a translucent component the preamble of claim 1 solved according to the in the characterizing Part of claim 1 further developed features is.

An advantageous use of such a component is Subject of the appended claim 8. Advantageous Embodiments of the invention are in the subclaims specified.

If at least one of the surfaces of the component, namely a main surface of a profile web of a glass profile element, provided with a rib structure which is made of or is formed with individual elongated, parallel ribs, which have a triangular shape in cross section, can thus a light guide device can be created with the light is specifically steerable. For example, light can enter the room too a specific area to be illuminated, for example the Ceiling to evenly illuminate the room as a whole, or to a workplace. This happens in each case through specific refraction or reflection of the light at the Triangular limb surfaces, the sum of which is a refractive or Form reflection surface. One has e.g. so no longer that Align device according to the given lighting, but can the component in accordance with the lighting needs in select the room. The introduced by the component Light output is not affected. There is also a seeming pattern. One advantage arises from the fact that the Ribs some mechanical reinforcement for the device result, so that weight is saved with the same stability can.

So that the special appearance and stability of the invention Component preserved even with large temperature fluctuations remains and against destruction - especially in case of burglary or the like - is well protected, as already indicated, according to a particularly advantageous embodiment hardened and / or partially toughened or toughened glass, especially multi or Single-pane safety glass provided as the material. at partially tempered glass will result in something in the event of breakage larger particles than in the case of breaking into very small and therefore harmless particle disintegrating toughened glass.

The invention sees a training as more translucent Profile block, for forming a wall component in front, with a Profile web and at least one profile leg. Here is the Invention because of its targeted light guide function versatile usable. This is how translucent wall areas become like windows or facade areas e.g. often with, for example, U-shaped Glass profile blocks built. The well-known glass profile blocks usually consist of clear glass or colored glass. According to the clear or milk glass structure of the known Glass profile blocks are always the same Surface impression, which is too boring for some builders. Though is made up of the individual by the construction of the wall element Glass profile blocks already have an attractive overall visual effect achieved. For static reasons or for heat or lighting-technical reasons is the design possibility of the The designer is usually limited, so that optical variations of wall components made of glass profile blocks according to the state the technology are built up, only with difficulty or correspondingly expensive are accomplished. Here it would be generally desirable translucent profile blocks to form a wall element have, with simple means amazing optical Impressions and appearances can be achieved.

This is also provided by the rib structure according to the invention Profile blocks accessible.

As a profile module, the invention has a profile leg Stabilize on, on which the profile block, for example masonry, steel scaffolding, truss or the like, formed above, on or between which the wall element should be attachable. One of the two main surfaces of the Profile web then forms part of the outward-facing

Surface of the wall element. Is now, as provided according to the invention, one of the main surfaces provided with the rib structure, so there are one depending on the perspective Viewer and depending on the orientation of each Triangle leg surfaces of the ribs very different optical impressions can be achieved. This applies both to the fact that only - as preferred because most visible - the front or outer Main surface is ribbed, as well as to ensure that the rear or inner main surface or both ribbed because the profile block is translucent, so too perceived a rib structure of the rear main surface. If light hits the triangular sides of the ribs, it will change depending Angle of incidence scattered, broken, reflected or pass through. It can be very pretty and amazing achieve optical effects, in particular through the structure of the Wall elements made of individual building blocks and according to the variety of possible arrangements and shapes of the ribs to a large extent are variable. In addition, the ribs give a certain mechanical reinforcement for the profile blocks, so that at same stability weight can be saved.

The advantages described above are particularly special Cross-sectional shape of the individual ribs back. Because the individual ribs are triangular in cross section, are on the Crest line sharp boundaries between each reflective or transmitting or refractive surfaces of the Triangle legs created. The triangle legs are preferred both (or just one of them) just designed, so that depending on the incidence of light or the angle of view a form a refractive or reflective surface.

Because of the advantageous use specified in claim 8 The glass profile component according to the invention can be in the vicinity confusing area because of the targeted Alignment of individual triangular leg surfaces at least so far be made visible that at least vaguely recognizable is that something on the confusing intersection, kink or Curve point too moved.

Often, more than just one area of the room should be especially light can be supplied, for example, two work surfaces in the Space created by the translucent component provided completion of the building is completed. Here would be the supply of light to two areas of the room desirable. On the other hand, it would be just at an intersection 237, as shown in Figure 16, advantageous if you have both Could see branches of the branching corridor 231. The The above-mentioned goals are in a particularly advantageous embodiment the invention achieved in that the ribs for Create a second refractive or reflective surface the second leg of the triangular shape a second level Have triangular leg surface.

It is advantageous to install a component according to the invention in a Wall element that closes the room and / or on a passage, one Passage, a staircase or a driveway or other way on which the confusing point is formed, is arranged. The wall element can be in a residential, office or commercial building, a manufacturing hall, a wall or any other building inside or outside. All in such wall elements or similar building closures located glass or other translucent components can by components according to the Invention to be replaced, which optimizes the lighting and / or security increases without the building's lighting or light supply negatively influence. Examples of confusing places are crossing, kinking or Curve points. With that there are also reversal points of stairs in glass, for example Stairwells meant.

Preferred versions, because they are easy to manufacture, are those in which the ribs in their longitudinal extent across the entire extend ribbed surface. A glass component designed in this way for example, by appropriately shaped rollers easy to manufacture. But of course there are also versions conceivable in which the rib structure only partially on the or Main surfaces or other with the ribbed structure provided surfaces are formed. The largest total area of refraction or total reflection area is achieved if the Ribs are arranged directly next to each other so that the ribbed surface has a zigzag line shape on average. Preferred hardened and / or partially pre-stressed or pre-stressed Glass materials are especially toughened safety glass and / or clear glass, float glass or cast glass and / or with one Increasing refractive power on the main surface, degrading or otherwise influencing coating provided Glass. The component does not have to be single-ply or be single layer, it is also the use of multi or Double glasses, whether conceivable as protective or insulating glass. The ribbed structure can also easily on one or multiple inner surfaces. In such a case the outer upper surfaces can also be made smooth. Internal ribs are due to the lower pollution and because of the impossibility of injury on sharper edges the ribs advantageous. On the other hand, an additional or both of the main surfaces are ribbed.

If the end of the building is a translucent wall of individual Profile blocks, it is sufficient in principle that of the profile blocks only one translucent profile block Glass, as the component according to the invention is designed. On such glass profile block according to the invention is with a Profile web and at least one profile leg provided, the ribbed structure formed on a surface of the profile web is. Depending on the fastening of the profile block be provided that the ribs parallel or perpendicular to the Profile legs are arranged trending.

Even if it is in principle conceivable that there is a difference between individuals Ribs flat surface areas are formed, as above mentioned because of the particularly large resulting refractive surface or reflective surface preferred that the or some of the Ribs are arranged directly next to each other so that the ribbed surface has a zigzag line shape on average and apex lines on and valley lines between the ribs are trained. The zigzag line does not have to be be regular, it is easily conceivable that for example the slope or side length of each triangle side of Rib increases to rib or otherwise varies. While this increases the solid angle that is specifically illuminated or the Viewing angle, but at the expense of light output or Reflectivity. With components with a uniform Zigzag structure - i.e. with ribs, the cross section of which have the same triangular shape, it is easier to optically create a uniform refractive surface or reflective surface, which is why this version is preferred.

How, especially in what direction, the ribs in their Longitudinal extension on the main surface or the other ribbed The surface run is from the room, the incidence of light and the desired area to be illuminated, which over the Refractive surface should be supplied with light or from the other desired light control, depending. If but the ribs in the profile block construction according to the invention running parallel or perpendicular to the profile leg are arranged, since the profile leg mostly either arranged vertically or horizontally to form the wall component horizontal rib structures will be formed more easily be the, for example, upper areas of the room For example, better illuminate the ceiling. Also revealed there are certain advantages in terms of manufacturing, since the Profile blocks during production are not unusual Angle must be rotated and thus a step compared to the production of profile blocks, in which legs and ribs do not run parallel or perpendicular, saved becomes. With perpendicular or parallel to the profile leg or legs trending ribs also sees from the outside through the sun illuminated wall component, from the same point of view considered, depending on the sunshine at noon quite different from morning or evening, although it gives an orderly impression regulated geometric shapes.

In principle, the two triangle legs would also be conceivable Treat ribs differently, for example colored differently or in particular to improve the To coat refractive power. If possible, however get the desired light transmittance of the wall component stay. It would therefore be conceivable to only use the flat triangular leg surfaces to coat on only one leg of the ribs or one semi-permeable coating.

In Fig. 1 is a glass block, i.e. a glass profile block 1 shown, which in section an L-shaped profile with a Profile web 2 with a first end 4 and a first end has opposite second end 5. The profile web 2 goes on the first end 4 at right angles into a profile leg 3, while it ends at the second end 5 plate-shaped, so that in Cut the L shape is created. The manufacture of the L-shaped Glass profile block 1 is done by cutting one in Fig. 2 shown U-shaped glass profile block 8, the two Ends 4, 5, each with one leg, the first profile leg 3 and a second profile leg 9, is provided along one Section line S. On the other hand, profile block 1 can also directly by rolling or shaping the glass in heated condition of the L-shape shown in FIG. The profile webs 2 of the glass profile blocks 1, 8 are on their profile legs 3, 9 facing away from the end face each with a first main surface 6 and on the side where the profile legs 3, 9 are located, provided with a second main surface 7. U-shaped Glass profile blocks are in clear glass versions with flat main surfaces 6 and 7 known per se. From the glass profile blocks 1 and 8 translucent wall elements similar to that Wall elements 18, 25, 18 ', 28, as shown in FIGS. 4, 7, 9 and 8 are shown form.

As can be seen in FIG. 3, at least one of the two Main surfaces 6, 7 with a ribbed structure with individual provided parallel ribs 11. At the in Fig. 3 shown glass profile block 10 in a second embodiment the ribs 11 are integral side by side on the first main surface 6 formed, so that this in section Zigzag line shape. The ribs 11 have the average Form a triangle and accordingly point to the side of the Main surface 6 a first flat triangular leg surface 12 and a second plane forming a vertex line 29 with the first Triangle leg surface 13. In the case of the glass profile module 10, since the ribs 11 are immediately adjacent, between the ribs 11 no flat areas but only valley lines 30 formed. The Glass profile block 10 is L-shaped in cross section, the Profile leg 3 is used for attachment to several Glass profile blocks 10 to form a wall element 18 (Fig. 4).

In Fig. 3 is an embodiment of a on a wall 15, a Scaffold or truss or the like fastened bracket 14 with two jaws 16 for holding the profile leg 3 recognizable. With corresponding holders 14 arranged at the same depth are the L-shaped glass profile blocks 10, for example end 4 at the end of 5 abutting to a not explicitly shown Wall component can be arranged. An overlapping structure as in Fig. 4 shown on wall component 18 is available if stacked brackets 14 on for different Clearances from the wall 15 or the like provide first and second or further bases 19 and 20 are attached. The Mounts 14 are so on the bases 19, 20 or the wall 15 or the like attached that the second ends 5 from the top Glass profile blocks 10 and the first ends 4 of the below arranged glass profile blocks 10 overlap so that Overlap areas 21 are formed. In the overlap areas 21 a passage 31 may be provided as shown. In a not explicitly shown are the Profile webs 2 adjacent glass profile blocks 10 to the Overlap areas 21 on or are by means of sealing elements sealed together. As can be seen in FIG Sealant 17 or thermal tapes or the like also provided between the jaws 16 and the profile leg 3.

As can be seen from FIG. 5, the third under a), under b) a fourth and under c) a fifth embodiment of Glass profile blocks 22, 23, 24 shows, the ribbed structure arranged on the first or the second main surface 6 or 7 his. In the U-shaped glass profile block 24 in the fifth embodiment (FIG. 5c)) the ribs 11 are spaced apart arranged from each other, so that not only valley lines 30, but whole flat surface areas 26 are formed in between. The flat regions 26 can, as shown in FIG. 7, also as Place for the profile legs 3, 9 of adjacent glass profile blocks 22 serve. The U-shaped shown in FIG. 5 Glass profile blocks 22, 23, 24 can be cut along the Section line S divided into two L-shaped glass profile blocks will or be.

6 are U- and L-shaped glass profile blocks in one sixth, seventh and eighth (see Fig. 6a), 6b), 6c)) embodiment shown, in which the ribs 11 are not parallel to the first and second profile legs 3, 9, but at right angles run on the first main surface 6. At the eighth Embodiment (Fig. 6c)), the ribs 11 even from the first main surface 6 continues seamlessly over the profile leg 3.

Different arrangements of the triangular leg surfaces 12, 13 to each other and those of adjacent ribs 11 show the ninth, tenth, eleventh and twelfth embodiment of glass profile blocks according to the representations a), b), c) and d) in Fig. 10. Basically, depending on the desired refractive area different angles of the triangular leg surfaces 12, 13 to each other possible. It is also possible that the adjacent ribs 11 like 10c) are not identical, but for example in one Direction to be more or more inclined or flattened are executed. Like the alignment of the triangular faces actually chosen must depend on the respective location and purpose of the glass profile blocks. This will continue explained in more detail below.

Fig. 11 shows embodiments of glass profile blocks, at which both main surfaces 6 and 7 of the profile webs 2 ribbed Structures in parallel or intersecting, in particular have rectangular arrangements relative to each other.

9, which is a wall component constructed similar to the wall component 18 18 'from the front (from the right in FIG. 4) the optical effect that the ribbed structures of the individual glass profile blocks 27 in the embodiment according to FIG. 6b) or 10 in the embodiment according to FIG. 3 in connection to have. The triangular leg surfaces 12, 13 reflect or transmit and refract light depending on the angle of incidence and perspective. Additional effects can be achieved through the overlap regions 21. The translucency of the glass profile blocks for lighting a space arranged behind the wall element 18 ' only slightly affected. It is targeted Direction of the light into the room depending on the inclination and Execution of the ribs 11 achievable. If the wall element on one Kink or crossing point, a curve or the like confusing places of passages or stairs or the like Because arranged so you can if the ribs 11 accordingly arranged and the triangular leg surfaces 12 or 13 are aligned accordingly, at least in reflection limited look around the corner, which helps collisions of people or vehicles among themselves without one the visual appearance or the incidence of light to have to attach a disturbing mirror.

FIG. 12 shows a space 47 to be illuminated, one of which Room wall here by a wall component 18 'comparable to however essentially only from glass profile blocks 10 with Profile legs vertical ribs 11 composite Wall component 18 ″, which is arranged behind a glass wall 49, is replaced. The ribs formed on the profile blocks 10 11 are designed and aligned such that the triangular leg surfaces 12 serve in their sum as a diffraction surface, which Directs daylight specifically to the ceiling 48.

13 shows the principle of deflection at a partial area 50 a glass wall with the ribbed structure. Light enters the glass via the main surface 7 and is on the main surface 6 depending on the inclination of the respective Triangle leg surface 12 or 13 of the ribs 11 by refraction or diffraction distracted.

14 and 15 are further embodiments of the Ribs 11 provided glass profile blocks 101, 112, 115 and 118 shown. They can be like the glass blocks 10, 22, 23, 23 ', 24, 27 for directing light through Refraction and / or reflection at the triangular leg surfaces 12, 13 the ribs 11 use, but are characterized in that they not just one layer but several layers of glass on at least one Partial area, in particular on the profile web 2, have. To do this the glass profile blocks 101, 112, 115 from FIG. 14 two sub-elements 102 and 103, 114 and 113 and 116 and 117 are assembled and the glass profile block 118 according to FIG. 15 is composed of three sub-elements 119, 120 and 121 composed. The sub-elements can Glass panel elements as for 102, 120 and 121 or even glass profile elements, in particular in L or U shape, such as 103, 113, 114, 116, 117 and 119, whose profile legs in whole or in part Form profile legs 3 and 9 if necessary.

Those for the glass profile modules according to FIGS. 14 and 15 assembled sub-elements are via edge connections 104, Edge joints 122 and / or spacers 130 or the like or in not shown Versions through large-area connecting means such as casting resins or the like connected. In the illustrated embodiments are between the individual sub-elements (e.g. Between 102 and 103, 119 and 120) insulating cavities 105, 123 created. The cavities 105, 123 can, depending on the application be filled with gas. This way is a two or Multi-pane insulating glass formed in profile or pane shape. In addition to the main surface (s) can also one or more inner surfaces with the Ribs 11 may be provided, as not shown here is. On the inside Ribs 11 arranged on the surface are against contact or dirt protected from the outside. As material for the in addition to the Glass profile elements provided with the ribbed surface Sub-elements 102, 114, 120, 121, those shown in the Embodiments are smooth on both main surfaces, come especially coated or uncoated, hardened or uncured float glasses or cast glasses. In not Versions shown are also one or more of the here smooth surfaces of one or some or each of the sub-elements 102, 114, 120, 121 provided with the ribs 11. The alignment of ribs 11 individual surfaces of a component can each other rectangular, parallel or at any other angle depending on desired refraction or reflection behavior and / or to be illuminated Areas.

Another possible use of glass components is in following in more detail with reference to Fig. 16, which is a known arrangement a door 233 provided with a glass pane 234 on one Intersection 237 of a first corridor 231 with a second corridor 232 shows, and Fig. 17 to 21 explained in more detail.

A person 238 indicated in FIG. 16 wants the room behind the If you reach door 233, you can only reach crossing 237 very late overlooked. This may be too late to collide with another person who is in the first hallway 232 on the intersection 237 too moved, or one pushed by this other person To prevent carriage 235. In contrast to the glass pane 234, the made of normal window glass with a flat main surface 6 is a sheet of glass (not included in the invention) 236, which is inserted according to FIG. 17 in the door 233 on which the Intersection 237 facing main surface 6 with the ribbed Structure with the ribs 11, the flat triangular leg surfaces Have 12 and 13 provided. The triangular leg surfaces 12 are each aligned so that the person 238 on its way to the Room the carriage 235 in one by the sum of the Triangle leg surfaces 12 formed reflection surface (see Example the obliquely hatched area of the glass profile blocks 10 in Fig. 9, which illustrates this effect) at least vaguely reflects and is warned. The formation of the ribs 11 the glass pane 236 is in principle in all variations as before for glass blocks 10, 2, 23, 23 ', 24, 27, 101, 112, 115, 118, described, so that the Glass pane 236 is adaptable to a wide variety of locations. Individual examples of comparable locations are for Glass profile blocks according to the invention are now based on FIGS. 18, 20 and 21.

In Fig. 18, the intersection 237 is again similar to that shown in Fig. 17, wherein but the wall carrying the door 233 here through a wall component 18 ' comparable, but essentially made of glass profile blocks 27 with Profile leg parallel ribs 11 composite wall component 18 '' replaced is. The ribs 11 formed on the profile blocks 27 are of this type trained and aligned that both the triangular leg surfaces 12 as the sum of the triangular leg surfaces 13 also serve as reflection surfaces, which allow a better overview of all parts of the intersection 237. This is by displaying a light source 239 in the second hallway 232 clarifies whose light rays represented by arrows on the triangular leg surfaces 12 and 13 are reflected and so in two branches of the first corridor 231 can be seen. Is moving now something between the light source and the intersection 237 on the Intersection 237, the light beams are interrupted and accordingly no longer reflected. One in the first hall 231 located (not explicitly shown) person would be warned.

The arrangement of the ribbed structure, so to speak, as less noticeable "Traffic mirror" is not just for right-angled intersections possible. In Fig. 19, the intersection 237 is of acute angle, one arranged in a window 240 as a window pane serving glass pane (not included in the invention) 241 die has ribbed structure and wherein the triangular leg surfaces 12 and 13 are adjusted accordingly in the angle. 20 is illustrates that a glass wall 242 in a stairwell 243 to improve the overview of the same on the stairs facing main surface 6 with the ribbed structure is. To the structure of the main surface 6 of the glass wall 242 clarify, it is very exaggerated and not with the correct alignment of the triangular leg surfaces 12 shown. In FIG. 21, the area of the glass wall encircled in FIG. 26 is 242 shown enlarged. The ribs 11 are not vertical, but horizontally aligned and very flat, so that the triangular leg surfaces 12 the lower region of the Stairwell 243 reflect upwards as this through the Arrows is indicated. The dash-dotted line represents that Plumb onto the reflective triangular leg surface.

The translucent components shown in the figures in Shape of the profile blocks 10, 22, 23, 23 ', 24, 27, 101, 112, 115, 118 can also be used in inconspicuous Way to improve security in and on buildings. they are not only for use inside the building, but also outside Suitable areas.
