Description

The present invention relates to a sitting or lying furniture with at least one electrically operable or operated unit.

The furniture may be, for example, a chair, in particular a padded seat, e.g. TV armchair or massage chair, act.

Such furniture is generally known (eg. DE102010002833 A1 or US7735931 B1 ). For example, an electric drive can be provided by means of which, for example, a backrest of the furniture can be adjusted. Power is always supplied by a cable that connects the furniture to the public power grid.

The disadvantage of this is that the cable restricts the mobility of the furniture. So the furniture must always be placed near a power outlet. Also, the cable can be a hindrance to a change of location of the furniture. Furthermore, the cable may pose a risk of tripping. Last but not least, a cable that extends from a piece of furniture to a socket is visually less appealing.

It is an object of the invention to provide a sitting or reclining furniture, which is supplied with electrical energy wirelessly.

The solution of this object is achieved by a device having the features of claim 1.

According to the invention, the sitting or lying furniture is directly connectable to and / or connected to an energy store, in particular accumulator, which forms an energy source for the unit. The energy store can preferably be attached directly to the furniture.

In this way, the sitting or lying furniture can be powered independently of the public power grid with electrical energy. The furniture is particularly self-sufficient with power. Disturbing cables are therefore not provided.

The energy store may preferably be rechargeable. Such a rechargeable battery can be used, for example, as lithium-ion rechargeable battery, lithium-cobalt dioxide rechargeable battery, lithium-polymer rechargeable battery, lithium-manganese rechargeable battery, lithium-iron-phosphate rechargeable battery, lithium-iron-yttrium-phosphate rechargeable battery, lithium-air rechargeable battery. Rechargeable battery, lithium titanate rechargeable battery, lithium sulfur rechargeable battery, lithium metal polymer rechargeable battery, sodium nickel chloride rechargeable battery, sodium sulfur rechargeable battery, nickel cadmium rechargeable battery, nickel iron rechargeable battery, nickel hydrogen Accumulator, nickel-metal hydride accumulator, nickel-zinc accumulator, lead accumulator, organic polymer, alkali-manganese accumulator, tin-sulfur lithium accumulator, silver-zinc accumulator, vanadium redox accumulator, zinc-bromine accumulator and / or silicon-air accumulator.

Alternatively, the energy storage device can also be designed as a primary cell, in particular as an alkali-manganese battery, zinc chloride battery or zinc-carbon battery. Also special batteries are conceivable, for example a zinc air battery, mercury oxide zinc battery, silver oxide zinc battery, nickel oxyhydroxide battery, lithium battery, lithium iron sulfide battery, aluminum air battery and / or biobattery.

Further developments of the invention can be found in the dependent claims, the description and the accompanying drawings.

According to one embodiment, the unit is designed as an adjustable footrest, headrest, armrest, backrest, massage unit and / or heating unit. For example, a piece of furniture can be moved from a sitting position to a lying position. Also, e.g. the height of the furniture can be electrically adjusted. In particular, the footrest, the headrest, the inclination of the backrest and / or the armrests can be electrically adjusted by preferably a drive of the unit is supplied with power from the energy storage. Furthermore, an electrically operable massage unit can be provided. It is also conceivable, in particular, a heating unit, which heats the furniture electrically. The furniture may comprise several different units, for example both an adjustable footrest and a heating unit.

Preferably, all electrical units of the furniture can be powered by a single energy store. Alternatively, multiple energy storage can be provided.

The control of the electrically operable unit can be done via a control module. This can be integrated into the furniture, for example an armrest, integrated or designed as, in particular wireless, remote control. A control by means of a smartphone or tablet is conceivable.

According to a further embodiment, the energy store is releasably coupled to the seating or reclining furniture and / or coupled. The energy store can thus be removed in particular from the furniture, for example for loading or in the event of a defect. A recharged energy storage or other energy storage can then be coupled back to the furniture to to provide the unit with energy. The coupling allows in particular a quick and easy replacement of the energy storage.

For coupling, a coupling element may be provided on the furniture, in particular a socket. In this socket, a plug of the energy storage can be plugged. Alternatively, a plug may be provided on the furniture as a coupling element, which e.g. can be connected to a socket of the energy storage.

According to one embodiment, the sitting or lying furniture comprises a socket for receiving a plug of the energy store, wherein the socket has at least one at least substantially rectangular, preferably square, extending recess. The rectangle or square formed by the depression may in particular have rounded corners. Preferably, two concentrically arranged recesses, in particular with parallel sides, may be provided.

According to the shape and number of wells, the plug can have projections which can engage in the recesses. For example, the plug may have at least one at least substantially rectangular, preferably square, extending projection. Preferably, two concentrically arranged projections, in particular with parallel sides, may be provided.

This embodiment of the socket makes it possible to attach the energy storage in different orientations on the socket. With a rectangular shape, for example, two different orientations are possible, while in a square shape four different orientations are conceivable. The coupling process is greatly facilitated because it does not have to pay attention to the orientation of the energy storage.

In addition to the socket, a further fastening element may be provided for the energy storage, whereby the energy storage in addition, especially without tools, can be secured to the furniture. Any locking, clicking, turning and / or screw connections are conceivable here.

For charging the energy storage can be easily removed and plugged into a charging station. The charging station can have recesses corresponding to those of the socket. Thus, the charging station may in particular have at least one at least substantially rectangular, preferably square, extending recess. Preferably, two concentric depressions, in particular with parallel sides, can be provided.

In particular, the charging station may comprise a, preferably optical and / or acoustic, signal unit, for example one or more LEDs which indicate the state of charge or the charging progress.

In an alternative embodiment, the energy storage can be firmly connected to the furniture or integrated into the furniture. For charging, such energy storage can be connected in particular via a power supply to the public power grid.

According to one embodiment, the energy store is arranged in a rear region of the piece of furniture, in particular on the rear side of the backrest. However, the energy storage device can in principle be arranged at any point of the furniture and integrated, for example, in one of the armrests.

In particular, the energy store can be arranged on or in a padding. Preferably, a metal plate may be provided on the frame of the furniture, to which a socket for the energy storage can be attached. One Reference of the furniture, the energy storage only a recess for a coupling element, so for example a socket or a plug, have. In any case, the energy storage is located outside the cover and thus easily accessible. For visual improvement, this can be hidden, for example, in a bag. Furthermore, it is possible to provide different apertures for the socket. For example, the panel may be adapted to the color of the cover. Preferably, the energy store can be arranged in a recess of the padding, in particular in the backrest or one of the armrests. When energy storage is used, the energy storage can fill the recess and so close flush with the rest of the padding.

In particular, the energy store may comprise a, preferably optical and / or acoustic, signal unit, for example one or more LEDs which indicate the state of charge. Preferably, a signal can be emitted when the state of charge falls below a certain threshold. It is also possible to display the state of charge in the control module.
