Description

The present invention relates to a blind device used by being incorporated in an insulating-glazing structure, the blind device being incorporated in a casing having one side open in the longitudinal direction and driven by an electric motor. A blind curtain is provided on the blind roller of the blind so that the blind curtain can be wound and unwound, and the blind roller is provided on both end surface sides of the casing, on a closed wall fitted in the casing in an airtight and liquid-tight manner. Regarding the supported format.

Insulating-glazing structures of different constructions are known. Usually, this glass-clad structure is a structure in which two or more glass plates are bonded or pressure-bonded to each other, and the inside of the unit is sealed to the outside in a substantially water vapor diffusion-tight manner (German Industrial Standard 52122). It is understood that This also applies to insulating-glasses which have a filter body of, for example, polyamide or sintered glass in order to obtain a pressure balance,
In this case, the filter body has, for example, a pore size of 10 ⁴ microns and, at a filter body diameter of 10 mm and 20 ° C., a gas permeability of, for example, 3 to 5 g / h mmHg.

Blinds with curtains of reflective material that serve as sunscreens are known. Insulating foils or sheets having such or similar properties are also known. Also well known are foils or thin sheets that have high transparency in the solar spectral range but very low emissivity. These foils or thin seals are now immovably clamped between glass sheets.

Such means have different drawbacks. Condensed water, for example, often adheres to the glass surface in foils with reflective material behind the glass plate. Although semi-permanent protection against sunlight is extremely effective under certain conditions, it can have adverse effects under other weather conditions.

Further, as a conventional technique, there is a glass-covered structure (German Patent Publication No. 3247970) in which one or more blind devices are provided in an intermediate chamber between glass plates. However, conventionally, it has been desired that this type of so-called “insulation-glass window with a blind” be made watertight. Proposals of arrangements which disclose practical solutions are not known (DE 2749418).

According to U.S. Pat. No. 3,253,644, a double-insulated-glazing structure is described which comprises an inner chamber which is completely closed to the outside. In this case, however, the folding blinds that are mounted are attracted or opened by a magnet from the outside, so that the glass surface is covered or opened. The operation from the outside is performed by a magnet, but it has a drawback that the blind does not move when resistance is generated in the moving mechanism of the folding blind. Furthermore, the blind-mounted construction of the insulating-glazing structure shown in the above-mentioned U.S. patent specification is not satisfactory in that it cannot be factory manufactured as a structural unit in advance.

DE-A 29 35 982 discloses an insulating-glazing structure with double glazing, in which case a blind with a rectangular cross section and one side open. The device casing is the upper closure of the double-insulated-glazing. In this case, the blind or the blind take-up roller having a curtain that can be taken up and paid out is driven and operated from the outside. Therefore, it is necessary to introduce the operation shaft from the outside into the casing in a watertight manner. is necessary. The known arrangement excludes the initially water-tight seal due to the movement of the drive shaft, even if the connection between the blind casing and the double-insulation-glazed structure, which has problems with the desired water-tight seal, is disregarded. Since the sealing means is worn, a failure is likely to occur over time. Therefore, in this configuration, there is a risk of invasion of moist air and condensation of water vapor, dust and the like inside the glass window.

Another construction of an insulating-glazing structure with light-blocking means, in which one blind device is provided between two glass plates of a double-insulating-glazing window, is described in DE-A 2314013. Has been known from. In this structure, an intermediate chamber is provided between both window glass plates, and by this intermediate chamber, all blinds can be arranged between the glass plates in a rolled-up state. However, in practice, such large glass plate spacing is not desirable.
This is because there are significant safety deficiencies. Therefore, the distance between the glass plates in a standard reliable insulating-glazing window is 12 to 15 mm, which is by no means sufficient to completely fit the blind between the two glass plates.

An object of the present invention is an insulating-blind device used by being assembled in a glazed structure, which is suitable for assembling in an insulating-glazed structure and manufacturing in a factory, and is insulated-
An object of the present invention is to provide a structure that can be easily assembled into a glass structure and used as a structural unit for an existing window frame.

The invention will now be described with reference to the illustrated embodiment.

FIG. 1 is a cross section of the upper portion of a window frame 1 having an insulating-glazing structure. The window frame 1 has an outer glass plate 19 and an inner glass plate 2. These glass plates 19, 20 form the main surface which limits the chamber 6 which is hermetically and liquid-tightly sealed, the upper side of which is a blind device 10 with a blind roller 8. The entire blind device is plugged onto the glass plates 19 and 20 in a manner similar to a bottle cork. The blind roller 8 has a blind curtain 4 in the form of, for example, stamped foil or a thin sheet. Reference numeral 16 indicates a blind curtain that is wound up. The blind roller 8 is a hermetically and liquid-tightly sealed casing made of metal, for example.
Surrounded by twelve. This casing 12 has at its upper and lower parts a support element 7,77 in the form of a longitudinal strip shaped as a support molding for the window frame 1 and the glass panes 19,20, and The side support element 7 has an associated packing 5 between the upper edges of the glass plates 19, 20. The casing 12 is on the outside,
It has a fixing means composed of a mold member 9 and a packing 169 for air-tightly and liquid-tightly connecting the casing to the glass plate 20. An insulating layer 3 made of an insulating material that blocks heat and sound is disposed inside the casing 12. The driving electric motor 14 arranged inside the blind roller 8 shown in FIG. As partially shown in FIG. 5, the power feeding conductor 13 is hermetically and liquid-tightly blinded through a so-called through-connection printed wiring board 23 having a small hole for conductively connecting the outside and the inside. It is installed in 10 inner chambers. However, instead of using such a printed wiring board 23, the feeding conductor may be cast in, for example, butyl rubber.

The blind curtain 4 is guided in a side guide rail. In addition to the side guide rails, it is also possible to provide floor guide rails. These rails prevent the ingress of moisture into the inner chamber 15 that is hermetically and liquid-tightly sealed, and prevent the glass plates 19, 2
In order to prevent any condensate from adhering to the mutually facing sides of 0, it can be filled, for example with silica gel. The glass plate and the entire blind device 10 are air-tightly and liquid-tightly connected to each other via packings 5 and 169 for assembling.

This window with an insulating-glazing structure is between the inside and the outside of the window when the blind curtain 4 in the form of a thin sheet is lowered through two spacers 30 fixed to the lower support element 7. Prevent radiation exchange at.

The spacing between the gas lath plates 19 and 20 is often 12 to 15 mm.
Intervals larger than this present a significant safety concern. Therefore, the blind device 10 must be constructed so as to be able to maintain the above-mentioned glass plate spacing that can be actually achieved.

According to the configuration of FIG. 1, both glass plates 19 and 20 are casing 1
It is shortened by the size of 2.

The shape of this casing 12, which is made of, for example, an aluminum plate or a plastic reinforced with glass fiber, is such that when the casing 12 is mounted on the glass plates 19 and 20, the glass plates 19 and 20 maintain their intervals. At the same time, it is chosen to abut the sealing layer of the backing 5, for example of butyl, at the lower support element 7 in the form of a longitudinal strip as a glass support molding of the casing. Due to this shape of the casing 12, the casing 12 is sealed to the glass sheet via the lower support element 7 and the packing 5 in the form of longitudinal strips.

FIG. 2 shows another embodiment, in which, according to this configuration, the blind device 10 is provided with an insulating-glazing structure by means of a support element 11 in the form of a closing longitudinal strip on the upper side of the casing 12. It is the upper closure of the unit.

Further, according to FIG. 2, the outer glass plate 19 has an edge portion.
The blind device 10 can be fitted into the structural unit of the insulating-glazing structure as an upper closure as described above, with 13 protruding upwards or the inner glass pane 20 being shortened. The fixing of the structural unit in the window frame is effected by a fixing and sealing element, as shown, in which case it is advantageous to use a joint belonging to the window. In order to eliminate the need to remove the entire blind device 10 in case of a failure of the blind device, for example, in the drive system, in the configuration of this embodiment, the closing wall of the casing is configured to be partially removable, in which case, A vapor-tight closure of the casing after repair is, of course, problem-free.

FIG. 3 is a partial perspective view of an upper portion of a glass-clad structure having two glass plates 19 and 20 with a blind device mounted on the upper side. In this case, a part of the spacer molding 31 is shown between the two glass plates 19 and 20, and the spacer molding 31 has a stepped portion at its upper end. This step serves as a stop for the spacer molding piece 21 on the side of the closing wall 18. The steam closure wall 18 serves as a lateral (end face) closure wall for a blind casing not shown in this figure. The closure wall 18 comprises in FIG. 3 a printed wiring board 23 having a power supply conductor 13 for an electric motor 14. When the blind device and the insulating-glazing structure are assembled, the printed wiring board 23 having the power supply conductor 13 serves as a side wall of the casing that closes the blind casing in an airtight and liquid-tight manner with respect to the outside.

FIG. 5 shows in section a casing part (closure wall 18) for drawing the power supply conductors for the electric motor 14 for driving the blind into the sealed blind casing. A pulse counter for counting the number of rotations of the electric motor 14 for controlling the limit switch of the electric motor 14 for driving the blind is provided for the purpose of automating the feeding or winding operation of the blind curtain 4 of the blind device 10. The electric circuit of the electric motor 14 can be interrupted after the number of revolutions of. In this case, the signal of the pulse counter is transmitted to the limit switch of the electric motor 14 through the cable and the printed wiring board 23 which is hermetically and liquid-tightly sealed and fitted.

FIG. 4 shows a construction similar to that of FIG. 3, in which the spacer molding 32, which holds a certain distance between the two glass plates 19 and 20, is constructed as a rectangular hollow molding closed in the circumferential direction. ing. The spacer molding piece 21 of the closing wall 18 has a shape adapted to the hollow cross section of the spacer molding 32, as can be seen from the drawing. The spacer molding 32 can have an integrally molded U-shaped cross-section molding (not shown) on the inside (blind curtain guide side), which serves for guiding the edge of the blind curtain and of the curtain. It also helps to avoid a slit of light between the rim and the spacer molding 32. The closure wall 18 is provided with a corresponding groove 17 for receiving the packing material and a valve 24 for evacuating the gas-tight and liquid-tight inner chamber. This valve 24 can be manufactured as the previously described filter body. It is also possible to form such a valve in the outer insulating glass plate and provide it in the blind casing by connecting it to the outside air.

The configuration of the embodiment is for an insulating-glazing structure that can be installed in a given window frame and is equipped with a blind device, so that the insulating-glazing structure is structurally compatible with the blind device. Is configured to.

The two glass plates 41, 42 are held at predetermined intervals by a commercially available spacer molding 43 in the range of their outer circumferences and are connected to this spacer molding 43 via, for example, butyl packing 69. Furthermore, a blind casing 44 with a blind roller 46 is shown on which a blind curtain 47 in the form of a blind thin sheet is wound. The free end of the blind curtain 47 is extended into the chamber 66 between the glass plates 41, 42. The blind casing 44 has support elements 50, 51 in the form of two elongated longitudinal strips. The support element 50 firmly holds the inner glass pane 41 against which the groove 73, also in the form of a longitudinal strip, on the upper side.
The support element 51 with is part of the upper closure of the insulating-glazing structure. As indicated by the dash-dotted line, this insulating-glazing structure with blinds also has in its upper edge region the standard dimensions of an insulating-glazing structure without blinds, and therefore also of the standard. Can be fitted into the window frame. One of the corners of the blind casing 44 is configured as a shaped part 53 as a swivel bearing shell, in which the shaped part 55 of the elongated swiveling shaped strip 54 is pressed and swung into this shaped part 53. Possibly supported and retained. The swivel profile 54 is held in its final assembled position by means of one hook-forming feature 57, 58 respectively on the blind casing 44 and the swivel profile 54. Forming part 55 of swivel forming strip 54
The end portion on the side opposite to is configured as a U-shaped holding rail 60, and has a rubber elastic holding or packing strip 61.
