Description

BRIEF DESCRIPTION OF THE FIGURES

[0050] In the following passages, the attached figures further illustrate typical embodiments of the invention and their advantages. The size ratios of the individual elements in the figures do not necessarily reflect the real size ratios. It is to be understood that in some instances various aspects of the invention may be shown exaggerated or enlarged in relation to other elements to facilitate an understanding of the invention.

[0051] FIG. 1 shows a schematic front view of the pane unit according to the invention

[0052] FIG. 2 shows a schematic sectional view of the one-piece illuminated pane

[0053] FIG. 3 shows a schematic sectional view of the frame structure

[0054] The same or equivalent elements of the invention are designated using identical reference characters. Furthermore and for the sake of clarity, only the reference characters relevant for describing the individual figures are provided. It should be understood that the detailed description and specific examples, while indicating preferred embodiments of the object according to the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.

DETAILED DESCRIPTION OF THE INVENTION

[0055] FIG. 1 shows a schematic front view of a preferred embodiment of the pane unit 1 according to the invention. The frame structure 2 comprises a one-piece transparent pane 3, and the frame structure 2 holds the pane 3 in the desired position. In this exemplary embodiment, the illuminable pane 4 is concealed by the transparent pane 3, with all elements of the pane unit 1 being constructed in a rectangular manner. However, it is also possible that the pane unit is formed by other shapes in other embodiments. It is likewise possible that the transparent pane 3 is formed in different sizes, forms, colors, etc. and/or has a multi-piece design.

[0056] FIG. 2 shows a schematic sectional view of a preferred embodiment of the one-piece, illuminated pane 4 of the pane unit 1. The sectional view illustrates the arrangement of lighting elements 5 on the illuminable pane 4. The frame structure 2 comprises an illuminable pane 4, which is illuminated from all four sides of the illuminable pane 4 by the lighting elements 5 arranged in the frame structure 2. In this context, the lighting elements 5 are integrated into the frame structure 2 and arranged in such a manner that an even light appearance is generated in the illuminable pane 4. In order to generate an even light appearance, the individual lighting elements 5 are regularly spaced apart in the FIG. 2, but in other embodiments, the lighting elements 5 can also be irregularly spaced apart and/or designed in pairs and/or as continuous light strip etc. The separate lighting elements 5 shown in the illustration can be designed as individual single light sources or in pairs, as fluorescent tubes, as light bands, etc. The rectangular design of the embodiment illustrated in FIG. 2 is not mandatory, and other embodiments of the invention can likewise be round, oval, or the like. The illuminable pane 4 can have one or more transparent panes 3 assigned to it, which can also be fitted into the frame structure.

[0057] FIG. 3 shows a schematic sectional view of a preferred embodiment of the frame structure 2 of the pane unit 1. The frame structure 2 locates the transparent panes 3, the illuminable panes 4, and the lighting elements 5 in the positions intended therefor and at a defined spacing. In this connection, the illuminable panes 4 are in each case shielded from the transparent panes 3 on both sides, with the space between the panes not being determined but being variable. The transparent panes 3 serve for the protection of the illuminable panes 4 from weather influences, damages, etc. The lighting elements 5 are in each case arranged on the sides 7 of the illuminable panes 4 in a therefor provided receptacle, and they can be fixedly located on the pane in other embodiment variants, or they can be accessible and removable. The switched-on lighting elements 5 illuminate the illuminable panes 4 and generate a homogeneous light field. In a preferred embodiment, it is possible with the lighting elements switched off to see through the illuminable panes and transparent panes. The hollow space 6 formed in the FIG. 3 by the arrangement of the multiple panes can be gas-tightly locked in such a manner that the hollow space 6 can fulfill an insulating function. The hollow space 6 can also be filled with various gases, liquids, etc., thus resulting in further possible uses and fields of application.

[0058] The embodiments, examples and alternatives of the preceding paragraphs, the claims, or the following figures and description, including any of their various aspects or respective individual features, may be taken independently or in any combination. Features described in connection with one embodiment are applicable to all embodiments, unless such features are incompatible.

[0059] If illustrations and aspects are generally referred to as being “schematic” in the context of the figures, this is by no means intended to imply that the illustration of the figures and their description are of inferior significance with regard to the disclosure of the invention. The person skilled in the art is fully capable of gathering sufficient information from the schematically and abstractly drawn illustrations for facilitating the understanding of the invention without the understanding being in any way impaired by, for example, the size ratios of the drawings of the pane unit and/or of parts of the object or of other of the elements being drawn and being potentially not precisely true to scale. On the basis of the concrete realizations of the object according to the invention explained in the figures, the person skilled in the art as a reader is thus enabled to derive a better understanding of the inventive idea, which is formulated in a more general and/or more abstract manner in the claims and in the general part of the description.

[0060] The invention has been described with reference to a preferred embodiment. Those skilled in the art will appreciate that numerous changes and modifications can be made to the preferred embodiments of the invention and that such changes and modifications can be made without departing from the spirit of the invention. It is therefore intended that the appended claims cover all such equivalent variations as fall within the true spirit and scope of the invention.
