Description

FIELD

The invention relates to a component such as a window, a door, a conservatory element, a balcony glazing or another partition with a pane space with changeable optical transparency, in particular for use as a privacy screen element or for the provision of sight protection.

BACKGROUND

From DE 698 262 a method and a device for the darkening of light surfaces in buildings is known. For this purpose, the space between two glass panes is filled with a fog or a gas so that light from inside the building can no longer escape to the outside. The fog or gas is located in an external storage container and, if necessary, is pumped into the space or extracted from there again.

Similar proposals are also known from DE 10 2006 009 620 A1, DE 202 11 924 U1, DE 22 49 543 A1 and EP 0 402 529 A1.

From FR 2 599 781, a device is known wherein a colored fluid such as a colored gas is introduced into a space, which may have technical or aesthetic purposes. A selective change in the color of the light passing between the glass panes is also known from U.S. Pat. No. 4,044,519. Colored liquids are used there. Similar approaches are known from EP 2 279 320, U.S. Pat. Nos. 2,378,591, 2,062,747, and DE GM 76 10 287, as well as from DE 10 2006 009 620 A1, DE 202 11 924 U1, DE 22 49 543 A1 and EP 0 402 529 A1.

In U.S. Pat. Nos. 2,489,751 and 2,373,214, the passage of light through a transparent roof of a vehicle is changed by introducing a liquid or fluid into a space between two glass panes.

FR 613 587 describes a headlight of a car that has two panes with a space between them, wherein the space can be temporarily filled with a colored fluid from a reservoir in order to dim the headlight.

DETAILED DESCRIPTION

FIG. 1 shows a top view from the front of a component 10 in the form of a window with a frame profile 25, in which a first glass pane 11 and a second glass pane 12 is inserted. Between the panes 11, 12 is a space 13, which is divided by means of, in various instances, an upwards and downwards movable separating device 24 into a first space area 14 and a second space area 15. Area-wise or circumferentially in the area of the frame profile 25, one or more lighting devices 16 such as LEDs or light bands are attached, which illuminate the interior of the first space area 14 and, in various instances, also the interior of the second space area 15. Furthermore, the component comprises an introduction device 17 for introducing fog or colored gas into the first space area 14 is provided, as well as a generating device 19 for the fog or the gas. This generating device 19 can be a fog machine, as it is known as such in the field of event technology. The introduction device 17 is, for example, a pump that is connected via a line through the frame profile 25 to the space 13. The introduction device 17 introduces the fog or the gas or alternatively another fluid such as a colored liquid into the first space area 14, so that the optical transparency there changes and the first space area 14, in various instances, becomes at least largely opaque. For the removal of the fog, gas or liquid, the component comprises a removal means 18, for example, a suction device. The introduction device 17 and the removal means 18 can be integrated in a common component. They can be arranged away from the frame profile 25 and connected to it via lines, but they can also be integrated in the frame profile 25 or in the separating device 24, which then has suitable introduction openings or suction openings. Furthermore, valves and seals are provided as required. The removal means 18 can also be arranged or connected in the lower area of the frame profile 25 and there be connected to the space 13 via an opening in the frame profile 25.

The generating device 19 can be combined with a storage device 22 for fog, gas or liquid. Alternatively, the generating device 19 can also be dispensed with and only a storage device 22 in the form of a tank or reservoir can be provided, which can be refilled if necessary. The introduction device 17 can also be simply designed as a pressurized container. The removal means 18 for removing the fog, gas or liquid can finally also be a simple drain valve or a drain or a drain opening, in particular in the lower area of the frame profile 25.

FIG. 2 shows a section through FIG. 1 along the section line shown in FIG. 1. One can also see here the second pane 12 as well as the frame profile 25 and the separating device 24 in sectional view.

FIG. 3 shows a section analogous to FIG. 2 through the component 10 in the form of a window in an exemplary alternative embodiment. In contrast to FIG. 1 or 2, the component 10 now also further includes a glass pane 20, which is in various instances connected or manufactured with the second glass pane 12 and the frame profile 25 as with commercially available double-glazed windows. The further pane 20 and the second pane 12 thus form a further space 21, which is formed like in commercially available double-glazed windows, i.e., in particular contains a vacuum or a heat-insulating gas. Of course, further panes and corresponding spaces can be provided (not shown), as is known with triple-glazed windows.

FIG. 4 shows a top view from the front of another alternative exemplary embodiment of the component 10 in the form of a window, wherein this time, in contrast to FIG. 1, no generating device 19 is provided but only a storage device 22 in form of a tank or reservoir. Furthermore, the introduction device 17 and the removal means for 18 are integrated in a single component in FIG. 4. This component can be a pump that can be switched between pumping into the space 13 and sucking out of the space 13. If the fluid contained in the storage device 22 is under pressure, it can also be sufficient to form the introduction device 17 as an inlet valve and the removal means 18 as an exhaust valve or to form both as a switchable inlet/outlet valve. In FIG. 4, the lighting device 16 is formed as a circumferential light strip.

The separating device 24 is, in various instances, movably designed, as is known in the case of blinds or roller shutters mounted inside multi-glazed windowpanes. The separating device 24 can be moved horizontally when arranged horizontally or vertically when arranged vertically, so that the space occupied by the fog or fluid increases or decreases. For this purpose, a corresponding adjustment device as it is known, for example, from roller shutter or blind drives, is provided, which can be mechanically or electrically driven.

The separating device 24 is, in various instances, provided with sealing devices such as sealing lips to separate the first space area 14 from the second space area 15 in a fluid-tight way, so that no or substantially no fog, gas or fluid passes over in an undesired manner from the first space area 14 to the second space area 15. The separating device 24 is, for example, formed as a movable hollow element, in various instances as a hollow round tube or rod, or as a movable, in various instances hollow beam. In this case, the generating device 19 and/or the storage device 22 and/or the removal means 18 can also be arranged inside the hollow element, wherein this element then in various instances has one or more openings to the first space area 14 through which the fluid or the fog can be introduced into the first space area 14 and can be removed from there again.

Overall, the component 10 is in various instances designed such that the first space area 14 filled with fog, gas or liquid is opaque or at least substantially opaque, so that the component 10 can be used as a privacy screen, darkening or dimming.

When using a fog, a colored gas, or a colored liquid, the component 10 can also be used for the aesthetic design of rooms, cabins, demarcated areas, balconies, windows, doors, etc.

Suitable fogs, gases or liquids and the corresponding generating devices are known, for example, from the field of event technology, where they are used, among other things, for show effects in music performances and in discotheques. The materials used there can also be used in the context of the present invention. The same applies to fog, gas or liquid generating devices and to corresponding storage devices such as tanks or reservoirs.

In an exemplary embodiment, the used fog or gas is white.

Due to the movably designed separating device 24, the first space area 14 can thus be specifically enlarged or reduced, so that a control of the area protected for example against view can be carried out.

As lighting device 16, commercially available light strips, chains of lights, laser arrangements, LEDs, incandescent lamps, etc. come into consideration, which are arranged, for example, in certain areas or circumferentially around the first space area 14 and illuminate its interior. By combining the lighting with the fog, colored gas or the colored liquid in it, aesthetically beautiful lighting effects, moving images or light surfaces can be created. In addition, the component 10 with the lighting device 16 can thus also serve to illuminate a room. The lighting in combination with the fog or colored gas or fluid causes an increase in the privacy through the fog or the fluid, as is known to every driver when driving in heavy fog and with bright lighting or when exposed to a bright light of oncoming traffic. The lighting and the fog or the gas create a light reflection that further reduces the optical transparency of the first space area 14 for the viewer and thus improves the privacy screen effect.

For maintenance and cleaning purposes, the component 10 is in various instances designed in such a way that the first pane 11 can be opened or the space 13 can be made accessible.

To control the optical transparency of the component 10 to a desired or preset level, a sensor system (e.g., a photo cell or a stray light detector with associated electronics) can be provided, which measures the light passage through the first space area 14 between the first and the second pane 11, 12 and correspondingly, depending on the desired degree of transparency, controls via a control device in various instances wired or wireless (e.g., via a WLAN) the quantity, the location of supply and/or the density of the supplied or discharged fog or fluid.

The control or regulation of the optical transparency of the component 10 to a desired or preset level can alternatively also be carried out purely manually wired or wirelessly (e.g., via a WLAN) via a control device with which, according to the desired degree of transparency, the quantity, the location of supply and/or the density of the supplied or discharged fog or fluid is changed.

In an exemplary embodiment of the invention, the control or regulation of the optical transparency of the component 10 to a desired or preset level is via a wireless connection, for example via a WLAN, and via a corresponding software, in particular with the help of a corresponding app, via which the control device for control or regulation of the optical transparency of the component 10 to a desired or preset level can be accessed. Such wireless control with the help of an app can again be either purely manual or in cooperation with a sensor system (e.g., a photocell or a stray light detector with associated electronics) that measures the light passage through the first space area 14 between the first and the second pane 11, 12 and correspondingly, depending on the desired degree of transparency, in various instances automatically controls the quantity, the location of supply and/or the density of the supplied or discharged fog or fluid.

The frame profile 25 is in various instances a hollow profile, as it is known from window construction. In this hollow profile, the required electrical or fluid lines can be integrated into it or carried through it.

The panes 11, 12, 20 can be formed as rigid glass panes but also as flexible panes or self-supporting transparent films. In particular, they can also be curved, i.e., the component 10 does not have to be flat but can also be half-cylindrically shaped, dome-shaped, hemispherically shaped, etc.

The supply of the component 10 with electrical energy is in various instances carried out by means of a battery or a rechargeable battery. However, it can also be connected to the electrical power supply. Particularly, in various instances, a solar cell is integrated in the component 10 or the electrical connection of the component 10 is integrated with a solar cell to thereby provide the required electrical energy.
