Input device, especially for a mobile telephone, module comprising an input device, mobile telephone and method for the production thereof
View Patent ↗The present disclosure relates to an input device, especially for a mobile telephone, a module comprising an input device and a method for the production of an input device and/or a module. An input device is provided, including, a module comprising an input device, a mobile telephone and a production method enabling improved permanent fixing of an input device to an/or inside a housing, whereby at mechanically stable fixing means is arranged between a first plane consisting of at least one cap and a second plane of a flexible carrier connected to the cap, such that the cap and the flexible carrier transmit force in a substantially punctual manner via a plane of a fixing means and the fixing means, in one area of at least one terminal edge, is configured in such a way it can secure the input device in or on a housing.
1. An input device, comprising:
a flexible carrier;
at least one cap connected to a top surface of the flexible carrier, wherein the cap is movable when force is applied to a surface of the cap; and
at least one fixing means, arranged beneath a first plane that includes the at least one cap, and above a second plane of the flexible carrier connected to the cap, wherein the at least one cap, and the flexible carrier, is configured in such a way that the force can be transmitted in a substantially punctual manner through a plane that includes the fixing means and wherein the fixing means, in one area of at least one terminal edge, secures the input device in or on a housing.
2. An input device according to claim 1 , wherein the fixing means comprises a metal sheet.
3. An input device according to claim 1 , wherein the fixing means is configured as a lattice with recesses, through which the at least one cap can move in a direction of actuation.
4. An input device according to claim 3 , further comprising at least one projection on the flexible carrier, wherein said at least one projection are configured to protrudes through the recesses in the stable fixing means and is covered by a respective at least one cap fixed on the projection.
5. An input device according to claim 1 , wherein the at least one cap has, perpendicular to a direction of actuation in at least one spatial direction, a dimension that is greater than an opening in the fixing means.
6. An input device according to claim 1 , wherein the cap is configured on an operable exterior or user interface to project over the respective recess and to protrude through the recesses.
7. An input device according to claim 1 , wherein the cap has, at least in one sectional plane parallel to the direction of actuation, an approximately mushroom-like cross-sectional form.
8. An input device according to claim 1 wherein at least one terminal edge of the fixing means is configured as a type of overlapping periphery and/or flange for securing the input device in or on a housing.
9. An input device according to claim 1 , wherein two respectively opposing terminal edges of the fixing means are configured as a type of overlapping periphery and/or flange.
10. An input device according to claim 1 , wherein fixing means is inserted loosely into the respective housing, especially where the span widths or opening widths of a housing aperture or of a keyboard opening are small.
11. An input device according to claim 1 , wherein the fixing means is connected to the housing rigidly and/or in one piece, whereby the fixing means is preferably configured as a punched and bent sheet-metal part.
12. An input device according to claim 1 , wherein the fixing means and an associated housing part are configured from one material and are manufactured in one piece in an essentially joint production step.
13. An input device according to claim 1 , wherein the fixing means forms a three-dimensional keypad surface or user interface.
14. An input device according to claim 1 , wherein the fixing means is configured as an ESD protection.
15. Input device according to claim 1 , wherein the input device is one of a mobile telephonic device and mobile computing device.
