Description
2082~40 Code: 393-16969 SPA~ING DEVICE FOR A TRANSPARENT INSULATING ARRANGEMENT
The invention relates to a spacing device for a transparent insulating arrangement in which in the space between two glass panes a transparent insulating material and possibly a movable protection device against overheating are arranged, wherein the glass panes in the area of the edges are held in a frame-like arrangement and by means of the spacing device are kept at a distance [from each other].
Such transparent insulating arrangements are to convert the energy of the sun into heat energy. The heat energy is obtained and used as an energy source. The principle and basic knowledge underlying transparent insulating devices are described, for example, in the print-out of the Fraunhofer Gesellschaft "Transparent Insulation Technology or Solar Energy Conversion,"
Fraunhofer Institute for Solar Energy Systems, Director: Dr. A.
Goetzberger (c) 1989, 1991, 2nd edition, pages 1-40.
The temperature fluctuations, occurring frequently in the air space between the glass panes, cause a type of pumping motion of the glass panes, wherein the glass panes move towards each other and away from each other. During this process, the spacing devices must be capable of absorbing these movements without special resistance and without the connection between the glass panes suffering from this. So far, this has not yet been achieved to a satisfactory degree. $he known devices are too rigid and survlve only relatively little play (pumping motions).
It is the task of the invention to create a spacing device which survives pumping motions nearly in an unlimited manner without the connection between the glass panes suffering [a negative effect].
'rhis task is solved by the characteristics of Claim 1.
Further, advantageous developments of the invention are characterized in the subclaims. By means of the figures, the invention is further explained in the following text in the form of examples. It is shown in:
Figure 1 a schematic cross section of a spacing device of a transparent insulating device;
Figure 2 a cross section through the expansion parts of the spacing device in accordance with Figure 1;
Figure 3 a schematic cross section of an additional spacing device of a transparent insulating device;
Figure 4 a cross-section through the expansion part with spacer tube of the spacing device in accordance with Figure 3;
Figure 5 an additional arrangement of a expansion part.
The partial area shown in Figure 1 of the transparent insulation device (1) does not show the transparent insulation material arranged in the intermediate space (2) between the glass panes (3,4) and does not show the protective device possibly present, both of which correspond to a known construction.
In the edge area (5) of the transparent insulation device (1), the space (2) between the glass panes (3, 4) is bridged all -around by means of a spacing device (6). From the outside, the transparent insulation device (1~ is held by means of a typical frame construction, also not shown.
rrhe spacing device (6), according to Figure 1, consists of two spacing tubes (7, 8), arranged parallei at a distance from each other, which are used in insulation glazings of typical construction and consist, for example, of aluminum and may be filled with a drying agent (9), wherein openings in the walls of the tubes (7, 8) assure a connection of the drying agent with the space (2) in a known manner.
Advantageously, between the inner surfaces of the glass panes (3,4) and the outer side walls of the spacing tubes (7,8), as usual, a butyl strip (10) is provided.
It is essential that in the space (11) between the spacing tubes (7,8) an expansion device (12) is provided which can absorb the pumping motion due to reversible elastic deformations. The expansion device (12) is constr~cted, in accordance with Figure 1, of two similarly formed, rod-like expansion parts (13a,13b) (see Figure 2) made, for example, of metal, particularly of aluminum.
Each expansion part (13a,13b) is produced, in accordance with Figure 2, in one piece of a metal strip, i.e.-, by lateral folds (15), extending in the longitudinal direction of the strip, wherein, between the folds (15), grooves (16), such as U-shaped grooves, remain. In the longitudinal central area of each expansion part (13a,13b) a broader groove (14a) with a broader base segment (14) is provided, its function being described in qreater detail below. For example, as shown, two folds (15) are provided on the one side and three folds (15) on the other side of the base segment (14) of the expansion part (13a,13b).
The expansion parts (13a,13b) may be closed and airculate inside the expanæion device (12). However, mere expansion pieces may also be used which are arranged at a distance from each other.
I'he expansion parts (13a and 13b) are inserted into each other in a comb-like manner and thus form the expansion device (12). Their position in the intertwining engagement accommodate the expansion parts (13a and 13b) such that the folds (5) of the expansion part (13a), respectively, abut against adjacent folds (15) of the other expansion part (13b), wherein the folds (15) of the two expansion parts are alternatingly arranged inside the expansion device (12) in sequence. As can be seen from Figure 1, the intertwining engagement of the expansion parts, except for the area of the additional central grooves (14a), results in a gapless sequence of the folds (14). The manner in which the comb-like engagement is achieved can be seen most clearly in Figure 2 in which the two expansion parts (13a,13b) are arranged opposite each other. From this initial position, the two expansion parts (13a,13b) are pushed or placed into each other in the direction of the arrow (17). The form-locking connection between the two expansion parts (13a and 13b) takes place from an initial position in which, respectively, the three folds of the one expansion part are opposite the two folds of the other expansion part.
The lateral ends of the expansion parts (13a,13b) vary in form, wherein the one end (18) is bent in the direction of the previous fold (15) at a distance to same and has approximately half the height of the folds (15). The other end (19) of the expansion parts (13a,13b) is essentially as long as the end (18) and, like same, is bent away from the preceding fold, however, it does not have a gap directly against the outside of this fold.
20824~0 If the expansion parts (13a,13b) are arranged in the manner shown in Figure 2 and are pushed into each other, then the fold of the one expansion part, preceding the end (19), extends between the end (18) and the preceding ~old (15) of the other expansion part, wherein the free edges of the ends (18 and 19) abut and thus form a smooth outer surface. In this way, the expansion device (12) is provided with smooth walls on both sides.
The connection of the expansion device (12) to the exterior tubes (7,8)'takes place with these smooth walls by means of a polyurethane filling compound (20). After the expansion device (12) has been placed centrally between the tubes (7 and 8), a gap remains between the expansion device and the abutting tubes spaces into which polyurethane is poured. Following hardening, this compound forms the circumferential segments (20). The polyurethane compound, which in itself is not elastic, adheres firmly to the material of the tubes (7,8), which preferably consist of aluminum Preferably, a polyurethane filling compound is used which consists of a mixture of a completely formulated phase-unstable, low-viscosity polyol formulation which contains a water-binding additive (Bydur VP PU 1397), and is produced with a liquid, solvent-free diphenylmethane-4,4'-diisocyanate with a content of isomeric and higher functioning homologues ('Desmodur 44 V 10 B or Desmodur'44 Y 20 B) (Bydur: manufacturer Bayer AG; Desmodur:
manufacturer Bayer AG). It is essential that the polyurethane segments (20) are torsion-resistant and~cannot be elastically deformed, so that the strlved for elasticity of the spacing device (6) is exclusively based on the elasticity of the 20824~0 expansion device (123. For this reason, the elasticity of the spacing device is achieved exclusively due to the accordion-like struct:ure of the expansion device (12), wherein the folds of the expansion parts (13a and 13b), which in the installation stage are tightly adjacent to each other during increasing heating of the surroundings, are able to unfold so that the material flaps abutting against each other inside each fold move away from each other in a more or less pronounced manner. This unfolding, taking place under the influence of heat, is reversed during increased cooling, so that the folds finally resume their tightly folded position with respect to the individual fold flaps, as is shown in Figure 1. This elastic deformation of the expansion device tl2) makes it possible for the glass panes (3 and 4) to work against each other in a friction-free manner during changing temperatures.
Moreover, in the central expansion device (12), a compression zone is formed which is composed of the central broader grooves (14a) and the pertaining central broad base segments (14). The possible compression range is determined by the distance of the folds facing each other in the area of the grooves (14a). A compression thus takes place such that the base segments (14) of the two expansion parts (13a,13b) facing each other in the vertical direction are bent outwardly or inwardly inside the expansion device (12), wherein this outward or inward bending can be reversed when the compression caused by lower temperatures is again cancelled out due to a rise of the surrounding temperatures. ~
The arrangement of the spacing arrangement shown in Figure 3 distinguishes itself from that according to Figure 1 in that, 20824~0 respectively, a portion of the expansion device (12) is made of a uniform material with the tube (7) or the tube (8). In Figure 4, such a tube-expansion device element (21) is shown in the uninstalled state and in a state without the drying agent ~9).
There, it becomes clear that the element (21) is bent and folded from a single metal strip, wherein the tube portion (22) form corresponds to the tubes (7 and 8) of FIgure 1. The expansion part portion (23), which connects on one side to the tube portion (22), consists of the accordion-like folded metal strip extension of the tube portion (22) and comprises a double layer of the folded metal. The folding, in contrast to the example according to Figure 1, is undertaken such that abutting folds are arranged at an angle to each other. In this way, the folds (15) of the expansion part may be pressed on each other ~in a manner] similar to a compression spring while the expansion part (23) is compressed, until the folds (15) extend essentially parallel to each other and rest against each wall. This compressed form is assumed by the expansion parts (23) when they face each other with the outer tube parts (22) being placed between the panes (3 and 4). The compression of the expansion parts (23) is achieved through a spacing profile (24) made of polyurethane which is placed between the front faces of the expansion parts (23) facing each other and which engages the same by circumferential lateral grooves in the spacing portion (24), which are engaged in a force-locking manner with protrusions (25) formed at the expansion parts (23). The space, located underneath the protrusions (25) between the two mutually facing expansion parts (23), is completely filled by the spacer (24) which extends with one head portion into the opposite upper space between the expansion parts (23). The space remaining there is filled by means of a polyurethane filling compound (26). In the hardened state, the polyurethane filling compound t26), together with the spacer (25) made of polyurethane and located thereunder, forms a circumferential rigid, nondeformable segment, which does not take part in the plastic deformability of the expansion device. The plastic expansion of the expansion device in Figure 3 takes place in a similar manner as in Figure 1 through a more or less extensive unfolding of the folds (15) of the expansion parts (23) under the effect of heat, wherein this unfolding is also reversible. In the example shown, the expansion parts (23) which are inserted in the compressed state achieve, over a range between the opposite glass panes (3,4) of approximately 5 mm, their relaxed position shown in Figure 4 in which the fold extends at an angle.
In Figures 1 and 3, against the underside of the spacing device (6), a sealing material layer abuts, and between the sealing material layer and the polyurethane segments (20) or the polyurethane spacer (24), a layer of butyl is provided.
In Figure 5, an alternative arrangement of the expansion device (12) of Figure 1 is shown. Here, the expansion device (12) again consists of two identically formed expansion parts (13a and 13b~. However, here, the foldings are meander-like at a distance [from each other]. The folds of the expansion parts (13a,13b) consist respectively of sections (30 and 31) which face each other and are in a straight line and curved section (32) connecting these sections, wherein the bending radius in the area of the section (32) is selected such that the straight sections 20~2440 (30 and 31), facing each other, have a predetermined distance from each other. In the central area of each expansion part (13a,13b), in the place of the curved section (32), a segment section (33) is provided which extends essentially perpendicular to the fold sections (30 and 31), so that in the central area of the expansion parts a greater distance of the straight-lined sections (30 and 31) facing each other results. In this way, a compression zone is formed similar to the compression zone of the expansion device (12) in Figure 1. Other than inside the compression zone, the fold sections (30,31,32) of the two expansion parts (13a,13b), placed into each other, abut closely and the ends of the expansion parts (13a,13b) are formed by tightly bent sections (34) at half the height which with sections of the folds of the adjacent expansion part, cut off ~ -appropriately at half the height, abut edge against edge, so that smooth connection surfaces are available which can be connected with the externally located tubes (7 and 8) of the spacer arrangement (6) by means of a polyurethane compound in the manner already described.
The invention relates to a spacing device for a transparent insulating arrangement in which in the space between two glass panes a transparent insulating material and possibly a movable protection device against overheating are arranged, wherein the glass panes in the area of the edges are held in a frame-like arrangement and by means of the spacing device are kept at a distance [from each other].
Such transparent insulating arrangements are to convert the energy of the sun into heat energy. The heat energy is obtained and used as an energy source. The principle and basic knowledge underlying transparent insulating devices are described, for example, in the print-out of the Fraunhofer Gesellschaft "Transparent Insulation Technology or Solar Energy Conversion,"
Fraunhofer Institute for Solar Energy Systems, Director: Dr. A.
Goetzberger (c) 1989, 1991, 2nd edition, pages 1-40.
The temperature fluctuations, occurring frequently in the air space between the glass panes, cause a type of pumping motion of the glass panes, wherein the glass panes move towards each other and away from each other. During this process, the spacing devices must be capable of absorbing these movements without special resistance and without the connection between the glass panes suffering from this. So far, this has not yet been achieved to a satisfactory degree. $he known devices are too rigid and survlve only relatively little play (pumping motions).
It is the task of the invention to create a spacing device which survives pumping motions nearly in an unlimited manner without the connection between the glass panes suffering [a negative effect].
'rhis task is solved by the characteristics of Claim 1.
Further, advantageous developments of the invention are characterized in the subclaims. By means of the figures, the invention is further explained in the following text in the form of examples. It is shown in:
Figure 1 a schematic cross section of a spacing device of a transparent insulating device;
Figure 2 a cross section through the expansion parts of the spacing device in accordance with Figure 1;
Figure 3 a schematic cross section of an additional spacing device of a transparent insulating device;
Figure 4 a cross-section through the expansion part with spacer tube of the spacing device in accordance with Figure 3;
Figure 5 an additional arrangement of a expansion part.
The partial area shown in Figure 1 of the transparent insulation device (1) does not show the transparent insulation material arranged in the intermediate space (2) between the glass panes (3,4) and does not show the protective device possibly present, both of which correspond to a known construction.
In the edge area (5) of the transparent insulation device (1), the space (2) between the glass panes (3, 4) is bridged all -around by means of a spacing device (6). From the outside, the transparent insulation device (1~ is held by means of a typical frame construction, also not shown.
rrhe spacing device (6), according to Figure 1, consists of two spacing tubes (7, 8), arranged parallei at a distance from each other, which are used in insulation glazings of typical construction and consist, for example, of aluminum and may be filled with a drying agent (9), wherein openings in the walls of the tubes (7, 8) assure a connection of the drying agent with the space (2) in a known manner.
Advantageously, between the inner surfaces of the glass panes (3,4) and the outer side walls of the spacing tubes (7,8), as usual, a butyl strip (10) is provided.
It is essential that in the space (11) between the spacing tubes (7,8) an expansion device (12) is provided which can absorb the pumping motion due to reversible elastic deformations. The expansion device (12) is constr~cted, in accordance with Figure 1, of two similarly formed, rod-like expansion parts (13a,13b) (see Figure 2) made, for example, of metal, particularly of aluminum.
Each expansion part (13a,13b) is produced, in accordance with Figure 2, in one piece of a metal strip, i.e.-, by lateral folds (15), extending in the longitudinal direction of the strip, wherein, between the folds (15), grooves (16), such as U-shaped grooves, remain. In the longitudinal central area of each expansion part (13a,13b) a broader groove (14a) with a broader base segment (14) is provided, its function being described in qreater detail below. For example, as shown, two folds (15) are provided on the one side and three folds (15) on the other side of the base segment (14) of the expansion part (13a,13b).
The expansion parts (13a,13b) may be closed and airculate inside the expanæion device (12). However, mere expansion pieces may also be used which are arranged at a distance from each other.
I'he expansion parts (13a and 13b) are inserted into each other in a comb-like manner and thus form the expansion device (12). Their position in the intertwining engagement accommodate the expansion parts (13a and 13b) such that the folds (5) of the expansion part (13a), respectively, abut against adjacent folds (15) of the other expansion part (13b), wherein the folds (15) of the two expansion parts are alternatingly arranged inside the expansion device (12) in sequence. As can be seen from Figure 1, the intertwining engagement of the expansion parts, except for the area of the additional central grooves (14a), results in a gapless sequence of the folds (14). The manner in which the comb-like engagement is achieved can be seen most clearly in Figure 2 in which the two expansion parts (13a,13b) are arranged opposite each other. From this initial position, the two expansion parts (13a,13b) are pushed or placed into each other in the direction of the arrow (17). The form-locking connection between the two expansion parts (13a and 13b) takes place from an initial position in which, respectively, the three folds of the one expansion part are opposite the two folds of the other expansion part.
The lateral ends of the expansion parts (13a,13b) vary in form, wherein the one end (18) is bent in the direction of the previous fold (15) at a distance to same and has approximately half the height of the folds (15). The other end (19) of the expansion parts (13a,13b) is essentially as long as the end (18) and, like same, is bent away from the preceding fold, however, it does not have a gap directly against the outside of this fold.
20824~0 If the expansion parts (13a,13b) are arranged in the manner shown in Figure 2 and are pushed into each other, then the fold of the one expansion part, preceding the end (19), extends between the end (18) and the preceding ~old (15) of the other expansion part, wherein the free edges of the ends (18 and 19) abut and thus form a smooth outer surface. In this way, the expansion device (12) is provided with smooth walls on both sides.
The connection of the expansion device (12) to the exterior tubes (7,8)'takes place with these smooth walls by means of a polyurethane filling compound (20). After the expansion device (12) has been placed centrally between the tubes (7 and 8), a gap remains between the expansion device and the abutting tubes spaces into which polyurethane is poured. Following hardening, this compound forms the circumferential segments (20). The polyurethane compound, which in itself is not elastic, adheres firmly to the material of the tubes (7,8), which preferably consist of aluminum Preferably, a polyurethane filling compound is used which consists of a mixture of a completely formulated phase-unstable, low-viscosity polyol formulation which contains a water-binding additive (Bydur VP PU 1397), and is produced with a liquid, solvent-free diphenylmethane-4,4'-diisocyanate with a content of isomeric and higher functioning homologues ('Desmodur 44 V 10 B or Desmodur'44 Y 20 B) (Bydur: manufacturer Bayer AG; Desmodur:
manufacturer Bayer AG). It is essential that the polyurethane segments (20) are torsion-resistant and~cannot be elastically deformed, so that the strlved for elasticity of the spacing device (6) is exclusively based on the elasticity of the 20824~0 expansion device (123. For this reason, the elasticity of the spacing device is achieved exclusively due to the accordion-like struct:ure of the expansion device (12), wherein the folds of the expansion parts (13a and 13b), which in the installation stage are tightly adjacent to each other during increasing heating of the surroundings, are able to unfold so that the material flaps abutting against each other inside each fold move away from each other in a more or less pronounced manner. This unfolding, taking place under the influence of heat, is reversed during increased cooling, so that the folds finally resume their tightly folded position with respect to the individual fold flaps, as is shown in Figure 1. This elastic deformation of the expansion device tl2) makes it possible for the glass panes (3 and 4) to work against each other in a friction-free manner during changing temperatures.
Moreover, in the central expansion device (12), a compression zone is formed which is composed of the central broader grooves (14a) and the pertaining central broad base segments (14). The possible compression range is determined by the distance of the folds facing each other in the area of the grooves (14a). A compression thus takes place such that the base segments (14) of the two expansion parts (13a,13b) facing each other in the vertical direction are bent outwardly or inwardly inside the expansion device (12), wherein this outward or inward bending can be reversed when the compression caused by lower temperatures is again cancelled out due to a rise of the surrounding temperatures. ~
The arrangement of the spacing arrangement shown in Figure 3 distinguishes itself from that according to Figure 1 in that, 20824~0 respectively, a portion of the expansion device (12) is made of a uniform material with the tube (7) or the tube (8). In Figure 4, such a tube-expansion device element (21) is shown in the uninstalled state and in a state without the drying agent ~9).
There, it becomes clear that the element (21) is bent and folded from a single metal strip, wherein the tube portion (22) form corresponds to the tubes (7 and 8) of FIgure 1. The expansion part portion (23), which connects on one side to the tube portion (22), consists of the accordion-like folded metal strip extension of the tube portion (22) and comprises a double layer of the folded metal. The folding, in contrast to the example according to Figure 1, is undertaken such that abutting folds are arranged at an angle to each other. In this way, the folds (15) of the expansion part may be pressed on each other ~in a manner] similar to a compression spring while the expansion part (23) is compressed, until the folds (15) extend essentially parallel to each other and rest against each wall. This compressed form is assumed by the expansion parts (23) when they face each other with the outer tube parts (22) being placed between the panes (3 and 4). The compression of the expansion parts (23) is achieved through a spacing profile (24) made of polyurethane which is placed between the front faces of the expansion parts (23) facing each other and which engages the same by circumferential lateral grooves in the spacing portion (24), which are engaged in a force-locking manner with protrusions (25) formed at the expansion parts (23). The space, located underneath the protrusions (25) between the two mutually facing expansion parts (23), is completely filled by the spacer (24) which extends with one head portion into the opposite upper space between the expansion parts (23). The space remaining there is filled by means of a polyurethane filling compound (26). In the hardened state, the polyurethane filling compound t26), together with the spacer (25) made of polyurethane and located thereunder, forms a circumferential rigid, nondeformable segment, which does not take part in the plastic deformability of the expansion device. The plastic expansion of the expansion device in Figure 3 takes place in a similar manner as in Figure 1 through a more or less extensive unfolding of the folds (15) of the expansion parts (23) under the effect of heat, wherein this unfolding is also reversible. In the example shown, the expansion parts (23) which are inserted in the compressed state achieve, over a range between the opposite glass panes (3,4) of approximately 5 mm, their relaxed position shown in Figure 4 in which the fold extends at an angle.
In Figures 1 and 3, against the underside of the spacing device (6), a sealing material layer abuts, and between the sealing material layer and the polyurethane segments (20) or the polyurethane spacer (24), a layer of butyl is provided.
In Figure 5, an alternative arrangement of the expansion device (12) of Figure 1 is shown. Here, the expansion device (12) again consists of two identically formed expansion parts (13a and 13b~. However, here, the foldings are meander-like at a distance [from each other]. The folds of the expansion parts (13a,13b) consist respectively of sections (30 and 31) which face each other and are in a straight line and curved section (32) connecting these sections, wherein the bending radius in the area of the section (32) is selected such that the straight sections 20~2440 (30 and 31), facing each other, have a predetermined distance from each other. In the central area of each expansion part (13a,13b), in the place of the curved section (32), a segment section (33) is provided which extends essentially perpendicular to the fold sections (30 and 31), so that in the central area of the expansion parts a greater distance of the straight-lined sections (30 and 31) facing each other results. In this way, a compression zone is formed similar to the compression zone of the expansion device (12) in Figure 1. Other than inside the compression zone, the fold sections (30,31,32) of the two expansion parts (13a,13b), placed into each other, abut closely and the ends of the expansion parts (13a,13b) are formed by tightly bent sections (34) at half the height which with sections of the folds of the adjacent expansion part, cut off ~ -appropriately at half the height, abut edge against edge, so that smooth connection surfaces are available which can be connected with the externally located tubes (7 and 8) of the spacer arrangement (6) by means of a polyurethane compound in the manner already described.
