The table device according to the invention accordingly combines several functions. So by the mere laying of an inductively loadable device on the table top, a power supply of this possible. An assembly and disassembly of charging and connecting cables is at least reduced. In this way, a large part of the table surface remains usable. The positioning of the loading device within the tabletop allows a visually appealing and easy to clean table top. At the same time, the design and legroom underneath the bottom of the tabletop are independent of the loader. Provision of power connections for external devices can be dispensed with entirely depending on requirements. Especially up-to-date smartphones with low battery life can be conveniently recharged on the table. Smartphones are increasingly being equipped with an inductive charging receiver. For this purpose, there are externally plug-in charging receivers and charging receivers integrated in the housing. With an increasing distribution of such Ladeempfängern in other mobile devices such as computers, notebooks, Ultrabooks, smartbooks and tablets is expected. Even inductively heated cups or powered fans can be operated on the table.
In addition, the tabletop device may be used as a control surface by the control unit located within the tabletop in conjunction with the touchpad to operate both on-the-desk and spaced-apart devices. For example, a projector can be operated without the need for a separate remote control. For wireless communication can be used here with the control unit an existing wireless Internet network or other wireless networks such as wireless display (WiDi) are used.
The inductive charging device can occupy a more or less large area of the table top. To mark the position of the charging device, for example, a mark on the surface of the table top and / or an LED can be used. Optionally, a plurality of inductive charging devices can be provided, which allow the independent charging of corresponding electrical devices at different positions of the table top. In an alternative embodiment, the inductive charging device covers an area which is large enough to be able to simultaneously position and charge several electrical devices thereon.
Preferably, the control unit and the charging device can be coupled to a power source via a common connection cable. In addition to a common cable so that a common power supply is available. The number of individual components is thus kept low. The cable guide can be loosened optically elegant if the connecting cable is led through the table top and through the table leg. In particular, table devices with a large central base on the table leg can then completely cover, for example, a floor socket, so that an invisible power supply is possible.
In a further embodiment of the table device, the upper side of the table top is closed at least in the area of the loading device. Thus, a fully usable and visually appealing table surface is provided above the loading device, which is also easy to clean. Furthermore, a special variant of the table device provides that the top of the table top is flat. Thus, the entire table can be used as a writing pad and storage space.
According to a special embodiment of the table device, the upper side of the table top is fluid-tight at least in the area of the loading device and / or the touch panel. This protects the charging device against liquids and does not have to be encapsulated separately. Preferably, the surface consists of a uniform material.
A preferred equipment of the table device provides that the charging device corresponds to a standard for wireless charging. This standard is, for example, the Qi standard of the Wireless Power Consortium, or other proprietary standard s (for wireless energy transmission using electromagnetic induction over short distances, such as the Alliance for Wireless Power (A4WP ®) or Power Matters Alliance PMA ® ). This ensures that the tabletop device is compatible with a variety of current and future devices. This also guarantees a long life of the table without loss of function.
Furthermore, in another optional configuration in the height direction between the top and the bottom of the table top, the table device has a control unit. This is communicatively connected to at least one touch panel (touch pad) on the top of the table top and outputs wireless control signals to external electrical devices (with processor), in particular mobile phones, computers, notebooks, ultrabooks, smartbooks and tablets.
According to a further embodiment of the table device, the control unit is wirelessly communicating with an external receiver unit, wherein the receiver unit cable interfaces, preferably HDMI interfaces, converts wireless control signals into wired signals, and conducts these wired signals at least to one of the cable interfaces. Consequently, it is not possible to control W-LAN-capable devices with the table device. Nevertheless, no cables have to be laid to the table, which is typically optically feasible only through a floor duct. Instead, the cabling of the devices with the receiver unit can be close to the wall, for example in a cabinet.
Specific configurations of the table device provide that the receiver unit is communicatively connected via a cable interface to at least one of the following devices: monitor, projector / beamer, TV receiver, digital signage system, video conferencing system, audio output device, or transmitting unit. By coupling the receiver unit to a projector or the like, image and sound signals can be transmitted wirelessly from coupled devices, such as a television set. Smartphones, tablet PCs, notebooks, etc. transferred. Overall, the table device can be individually adapted to a variety of different applications. In particular, the coupling of the receiver unit with a (wireless) transmitting unit makes it possible to integrate wireless transmission standards, which are not supported by the control unit, in a simple manner in the communication. Modifications to the table top or the table leg are not necessary. The implementation is carried out by integration of new technical components in the area of the externally arranged receiver unit.
Preferably, at least one display element, which is designed in particular as an LED, integrated in the table top. For example, it can be used to display a charge regardless of the device. It is also possible to display a selection of the signal source via the display element. Also, for example, the concerns of a power supply via a display element can be displayed. In particular, a plurality of display elements, in particular a plurality of LEDs can be provided in order to simultaneously be able to image a plurality of information.
