Glass keyboard, and method for producing a glass keyboard
First Claim
1. A glass keyboard comprising a keyboard surface (4) made from a flexible thin glass pane (2) and at least one carrier material pane (6), each pane being provided on opposing faces with an electroconductive layer (8, 10), the opposing electroconductive layers (8, 10) being kept at a distance from each other by a spacer (12), the electroconductive layers (8, 10) touch each other when pressure is applied to the flexible thin glass pane (2) at an essentially localized area of pressure application, the electroconductive layers (8, 10) on the thin glass pane (2) and the carrier material pane (6) being connected with respective conductors (62, 66) which are led out at a side edge of the keyboard surface (4), flexible flat multiple cables (64, 68) being connected respectively with the conductors (62, 66) of the electroconductive layers (8, 10) via contacts (74, 75),the flat multiple cables (64, 68) and the contacts (74, 75) being arranged between the thin glass pane (2) and the carrier material pane (6), and the flat multiple cables (64, 68) are in side-by-side relationship to each other.

Abstract
In a glass keyboard comprising a keyboard surface (4) made from a flexible thin glass pane (2) and at least one carrier material pane (6), each pane being provided with an electroconductive layer (8,10) on the faces facing each other, wherein the opposing electroconductive layers (8,10) are kept at a distance to each other with the aid of a spacer (12), and wherein the electroconductive layers (8,10) touch each other when pressure is applied to the flexible thin glass layer (2) at the essentially localized place of pressure application, it is provided that the electroconductive layers (8,10) on the thin glass pane (2) and the carrier material pane (6) are connected with conductors (62,66) which are led out at a side edge of the keyboard surface (4), that a flexible flat multiple cable (64,68) is connected with the conductors (62,66) of the electroconductive layers (8,10) via contacts (74,75), and that the flat multiple cable (64,68) comprising the contacts (74,75) is arranged between the thin glass pane (2) and the carrier material pane (6).

- 16. A method of producing a glass keyboard comprising the steps of providing a keyboard surface (4) made from a flexible thin glass pane (2) and at least one carrier material pane (6), the panes having an electroconductive layer (8, 10) on respective faces facing each other, maintaining the opposing electroconductive layers (8, 10) at a distance to each other by a spacer (12), effecting contact between the electroconductive layers (8, 10) by applying pressure to the flexible thin glass pane (2) at an essentially localized area of pressure application, leading the electroconductive layers (8, 10) peripherally outwardly from between the thin glass pane (2) and the carrier material pane (6) by conductors (62, 66) at a side edge of the keyboard surface (4), electrically connecting flexible flat multiple side-by-side cables (64, 68) respectively with the conductors (62, 66) of the thin glass pane (2) and the carrier material pane (6) and gluing the flexible flat multiple cables (64, 68) respectively to the thin glass pane (2) and the carrier material pane (6), and subsequently gluing the thin glass pane (2) and the carrier material pane (6) to each other using an adhesive as a spacer (12) which at least in part sets-off gaps in each of which is housed conductors (74, 75) of said respective flat multiple cables (64, 68).
