Abstract

A method for manufacturing a sensor for a part of a piece of furniture is described, in which method a layer, necessary for the actual sensor function, of the sensor is printed onto the part of the piece of furniture. Furthermore, a corresponding sensor, a part of the piece of furniture, a switching device and a piece of furniture are presented.

First claim

The invention claimed is:

1. A method for manufacturing first and second sensors for a part of a piece of furniture, the furniture including a furniture carcass, the method comprising: providing a recess having first dimensions in an inner surface of the part of the piece of furniture, printing at least a sensor functional layer of the first sensor onto the outer surface of the part of the piece of furniture, and
printing at least a sensor functional layer of the second sensor in the recess defined in the inner surface of the part of the piece of furniture, the second sensor having second dimensions substantially the same as the first dimensions, thereby defining a second sensor outer surface substantially aligned with the inner surface of the part of the piece of furniture, the inner surface of the part of the piece of furniture opposing the furniture carcass, the first sensor being a trigger activating a drive unit which drives the part of the piece of furniture relative to the furniture carcass, the second sensor detecting a bearing of the part of the part of the piece of furniture on the furniture carcass,
wherein a detection device provided in the furniture carcass detects changes in state at the first and second sensors, the changes in state being transmitted from the first and second sensors, and includes a signal link to the drive unit, and
wherein a damping device provided in the furniture carcass supplies energy to the detection device.

2. The method as claimed in claim 1 , wherein a plurality of layers of at least one of the first and second sensors are printed onto the part of the piece of furniture.

3. The method as claimed in claim 1 , wherein at least one of the first and second sensors is manufactured with one or more layers thereof printed onto the part of the piece of furniture.

4. The method as claimed in claim 1 , wherein at least one line which is for transmission of energy and/or signals and is connected to at least one of the first and second sensors is printed onto the part of the piece of furniture.

5. The method as claimed in claim 1 , wherein a signal transmission device for a signal of at least one of the first and second sensors is printed onto the part of the piece of furniture.

6. The method as claimed in claim 1 , wherein an energy supply device for at least one of the first and second sensors is printed onto the part of the piece of furniture.

7. The method as claimed in claim 1 , wherein after printing the at least the sensor functional layer of the first sensor onto the outer surface of the part of the piece of furniture, a protective layer is applied over the first sensor.

8. The method as claimed in claim 1 , wherein a printing preparation layer is applied onto the part of the piece of furniture before the at least the sensor functional layer of the first sensor is printed onto the outer surface of the part of the piece of furniture.

9. The method as claimed in claim 1 , wherein the at least the sensor functional layer of the first sensor is printed onto the outer surface of the part of the piece of furniture before an electrical or an electronic component is mounted on the part of the piece of furniture.

10. The method as claimed in claim 1 , wherein the at least the sensor functional layer of the first sensor is printed onto the outer surface of the part of the piece of furniture after an electrical or an electronic component has been mounted on the part of the piece of furniture.

11. A method for manufacturing a movable furniture part having sensors provided thereon, the method comprising:
printing at least one sensor layer of at least a first sensor on a first surface of the movable furniture part, the first sensor being a trigger activating a drive unit which drives the movable furniture part relative to a furniture carcass; and
providing a recess having first dimensions in a second surface of the movable furniture part opposite the first surface thereof and opposing the furniture carcass;
printing at least one sensor layer of a second sensor having second dimensions substantially the same as the first dimensions in the recess, thereby defining a second sensor outer surface substantially aligned with the inner surface, the second sensor detecting a bearing of the part of the piece of furniture on the furniture carcass;
wherein the printing comprises one of relief printing, flat printing, or screen printing.
