Description

The The invention relates to tables with at least one driven height adjustable Table top, with the table top on via an adjustment mechanism in their length changeable table legs or Side stands is coupled.

Furniture are adjustable with a drive components known. In particular, an electric motor is used as drive Use, via an electric power grid as a voltage source is operated. The latter is the existing low-voltage grid.

In order to ensure operation even in the event of a power failure, the electric motor is connected or connectable to an accumulator or a battery. Such solutions are inter alia from the publications DE 200 12 072 U1 and DE 200 13 673 U1 known. The capacity of a battery or a rechargeable battery is limited, so that a permanent operation can not be guaranteed.

Of the The protection claimed in claim 1 is based on the object a table with at least one powered height-adjustable table top to operate independently.

These Task is with the features listed in the protection claim 1 solved.

The Tables with at least one powered height-adjustable Table top, with the table top on via an adjustment mechanism in their length changeable table legs or Side stands coupled, in particular, stand out characterized in that the at least one drive is autonomously operable.

To Solar cells are part of the table. The solar cells are over a charger with at least one accumulator interconnected. This is still via a switch with at least connected to an electric motor as part of the adjustment mechanism, so that the tabletop over the electric motor is self-sufficient in its height is adjustable.

Of the Electric motor is operated by the accumulator as an energy source. The latter is about the solar cells as part of loaded the table. Since it is assumed that a height adjustment is not constantly made, is the operating state Allowable for a long time, even without the one Charge done. The consumed in the height adjustment electrical energy is returned to the accumulator via the Solar cells fed.

solar cells it is known to convert electromagnetic radiation, for example the radiant power of sunlight, directly into electrical energy, wherein the internal photoelectric effect of the solar cell is used.

By the discontinuous and only occasionally necessary operation, is the charging of the accumulator with those existing at the workplace Electromagnetic rays easily possible. Even at Darkness is more electromagnetic and available to the Working necessary bulbs for loading available. This is one constant operational readiness secured.

The Charging takes place via the charger, being the right one Charging and protection against over- and undercharging takes place. This ensures a long life of the battery. For this purpose, a known charge controller is used as part of the charger.

One Another advantage of the table is the existing low voltage. Special Protective measures are not necessary. This can also be a repeated Testing the safe operation of otherwise using a low voltage powered electric motors omitted.

The Solar cells as components of the table are at the most diverse Components of the table placed or placeable. The skill Of course, attachments or accessories be.

In order to the height adjustment can be self-sufficient. A power network including a connection to this is not necessary. Otherwise to use cable connections including their problems regarding their installation and resulting Dangers are eliminated.

advantageous Embodiments of the invention are in the claims 2 to 8 indicated.

The Solar cells are located after the development of the protection claim 2 Conveniently on at least one area of the table top and / or a cover of a side stand and / or one with the panel connected to the table and / or one connected to the table Facility. In a further embodiment, the Solar cells a component of the table top and / or the panel a side stand and / or the one connected to the table Shutter and / or the device connected to the table.

The Solar cells are according to the embodiment of the protection claim 3 semiconductor solar cells or organic solar cells.

Solar cells are made of semiconductor materials known and are constructed in principle like large-area photodiodes. They are operated as a power source. Organic solar cells are made of plastics that have electrically semiconducting properties. Known organic solar cells consist for example of conjugated polymers and molecules. The organic solar cells can be advantageously produced economically favorable. In addition, these have the mechanical properties of plastics, are flexible, transparent and easy to handle. They can also be realized in different colors, so that they can be used at the same time as style and decorative elements.

The Charger consists of the development of the protection claim 4 of a charging circuit and a protection circuit for the accumulator.

at The charging circuit is, for example, an intelligent one Charging circuit. In addition, the full charge of the connected Accumulator safely detected.

The Protective circuit advantageously prevents overtemperature or short circuit. With these measures is the life of the accumulator increases.

Of the Adjusting mechanism is according to the embodiment of the protection claim 5 a threaded spindle / nut system, a gear / rack system or a traction drive. Such systems and shoots are known.

at a threaded spindle / nut system is the threaded spindle driven so that with non-rotating nut this in the height is adjusted. In a gear / rack system the gear is driven so that the gear is in position changed with regard to the rack.

One Traction drive is known to be two spaced apart arranged rolls, discs or wheels over the traction means are interconnected. This system is located on the height-adjusting part. The traction means is located continue at one opposite the höhenzuverstellendem Part fixed part. The amount of adjustment will be determined by the distance of the rollers, discs or wheels. To adjust the height, one of the rollers, one of the discs or a wheel driven. The respective other role, disc or the Respective other wheel serve the diversion. As a traction means is advantageously used an un-articulated traction device. The latter is for example a rope or a belt. Accordingly, the rollers, discs or wheels formed.

Of the Electric motor is according to the embodiment of the protection claim 6 with the adjustment mechanisms of the table legs or side stand connected.

conveniently, consist of variable in length table legs or side stand made of telescoping and leading / guided parts.

Of the Accumulator is according to the embodiment of the protection claim 8 with at least part of a connector for releasable Connecting and operating electrical appliances connected. This can also be used by other electrical devices be operated of the accumulator.

One Embodiment of the invention is in the drawing illustrated in principle and will be described in more detail below.

It show the

FIG. a table with at least one powered height-adjustable Tabletop.

A table with at least one powered height-adjustable table top 1 essentially consists of a tabletop 1 , Side uprights 2 , an adjustment mechanism 3 for the side stand 2 an electric motor 4 , an accumulator 5 , a charger 6 and solar cells 7 ,

The figure shows a table with at least one driven height-adjustable table top 1 in a schematic representation.
