In the furniture sector furniture with a furniture body to which a driven movably guided furniture part is added, known.

The movement influence of the furniture part or its movement specification takes place in particular via a movable actuator by means of a drive, which moves the furniture part relative to the furniture body in motion, in particular in at least one direction of movement of the furniture part.

Purpose and advantages of the invention

Object of the present invention is to improve the operation of arrangements in the aforementioned type, especially with regard to ease of use of the furniture or on a drive-side assembly and / or operating costs.

This object is solved by the independent claims.

The dependent claims are directed to expedient and advantageous variants of the invention.

The invention relates to a device for controlling the movement of a movably received on a furniture body furniture part, wherein the device comprises an electrically operable actuator, so that in the mounted state of the device depending on the operation of the actuator, the furniture part is driven relative to the furniture body by means of the actuator movable ,

The actuator may for example be a driven pivotable or linearly driven movable element. Depending on the movement or change in position of the actuator, the furniture part is moved out relative to the furniture body or herausschwenkbar and / or movable in the opposite direction.

The furniture part can be moved completely driven by a possible path of movement or be movable only over a section and otherwise by manual action of a person.

The actuator is movable in particular via an electric motor. The device comprises in particular a control unit, for example a control or control unit, which controls the operation of the actuator, in particular its movement or its drive.

The furniture part may be, for example, a drawer, an extract, a furniture door or a furniture flap.

The first essential aspect of the invention is that recovery means are provided for recovering electrical energy from an energy source present in the vicinity of the recovery means, the recovery means being designed to supply electrical power to an existing electrically operating activator, and the activator for triggering the operation of the actuator is provided by an operating action from the outside.

Advantageously, in particular, no wired supply to the activator must be provided or installed by a remote or external energy source. This is advantageous in terms of the installation and the state of use of the furniture.

The activator is used in particular to initiate a desired operating state with regard to the driven movement of the furniture part, depending on the user's request. The activator can, for example, a control element such. B. be an actuatable switch. The activator may preferably be operable from the outside or an operating side of the furniture, in particular be present on the furniture body or on the furniture part. Thus, for example, based on a done via the activator operator or trigger action by a person, for. B. by manual operation, electrical energy for the operation of the activator on the extraction means are provided. It can be delivered by the action of the person, the non-wired form of energy, which is then provided by the extraction means in electrical energy for the operation of the activator. With the associated power supply of the activator, this triggers the operation of the actuator, so that in the sequence of the driven actuator, the movable furniture part is driven driven as desired by the user. In this case, the actuator may have a wired, in particular conventional power supply or have a different power supply.

The activator may be remote from the control unit and / or the drive of the actuator. If no cable connection of the activator is set up, advantageously a wireless communication between the activator z. B. set up via the activator signals and a receiver of the signals, so that in the sequence of the command for operating the actuator is carried out and thus the furniture part is driven driven. The communication between the activator and the actuator or the receiver acting on the actuator happens in particular by means of a signal transmission by radio.

Advantageously, the necessary amount of electrical energy for signal transmission from the transmitter of the activator to the receiver in the order that possibly z. B. alone the mechanical energy form such. B. pressure forces, which is provided by an external action by a person on the activator, is sufficient that the electrical energy generated by the extraction means allows the signal transmission.

Thus, it is particularly advantageous possible to operate the activator completely independent of an external power supply network.

It is particularly advantageous if the activator is designed as an RFID chip (RFID: radio-frequency identification) or comprises such. In this case, the energy can be collected in the form of electromagnetic radiation and processed energetically, in particular passive RFIDs are used. A passive transponder removes the operating voltage from the electromagnetic field, whereby a part of the energy is reflected to a reading device.

Another essential aspect of the invention is that extraction means are provided for obtaining electrical energy from an energy source that is not conducted in the vicinity of the extraction means, the extraction means being designed to supply the actuator with electrical energy.

The above-mentioned advantages arise accordingly for the operation of the actuator. In this case, therefore, the driven movement of the movable furniture part is made possible by the actuator or its drive by electrical energy generated by the extraction means.

Particularly advantageously, both the activator and the actuator can be operated solely with the electrical energy which is provided by the extraction means. The operation of the furniture can thus be realized completely detached from an external or wired near reaching energy supply.

The forms of energy accessible to the means of production for the generation of electrical energy are based on a wide variety of phenomena or, in particular, comprise mechanical energy, electromagnetic or thermal energy. For example, light energy or energy from radio waves or energy from sound or pressure wave events can be used.

Furthermore, it is advantageous that the extraction means comprise a conversion element which is designed to generate electrical energy upon application of force to the conversion element. With the conversion element, for example, mechanical effects, wherein a force or a pressure acts on the conversion element, are used to generate electrical energy. The conversion element can be acted upon directly or indirectly, for example by pressure or force transmission from the point of action, for example, to the furniture carcass or the furniture part to the conversion element where the actual conversion into electrical energy takes place. The energy production described is based in particular on the piezoelectric effect, wherein the extraction means comprise in particular a piezoelectric element.

It is also advantageous that the extraction means comprise a radio switch with a piezoelectric element. Advantageously, the electrical energy which is necessary for a radio signal of the radio switch can be provided by the piezoelectric element. In this case, in particular by a manual operation or -auslösung the wireless switch on the piezoelectric element effective or usable mechanical energy or pressure energy is converted into electrical voltage. It is also advantageous that the transmission of a signal from the radio switch to a receiving unit is realized wirelessly by acting on the radio switch. The receiving unit communicates with the control unit or is in particular part of the control unit. The control unit then processes the received signal from the radio switch and triggers depending on the drive of the actuator or controls it so that in the sequence the driven movement of the furniture part takes place in the desired manner.

According to an advantageous modification of the subject invention, the extraction means are configured to generate electrical energy from a high-frequency electromagnetic alternating field. Thus, for example, radio waves can be used to generate electrical energy. This is advantageous because radio waves are usually permanent or everywhere.

Further, it is advantageous that the extraction means comprise a transponder with an antenna, so that in the presence of a high-frequency alternating electromagnetic field, the high-frequency energy is used for the production of electrical energy.

This is a particularly convenient and advantageous variant for energy generation. In particular, the form of energy used to obtain the electrical energy is advantageously not body-bound present and not linked to an action of the user of the furniture.

A further advantageous variant of the invention is characterized in that the extraction means comprise mechanical components which are designed to produce a structure-borne noise in the furniture carcass and / or the movably received furniture part upon exposure from outside to a body. The body is in particular part of the mechanical components. By means of the body, the structure-borne sound is generated depending on the type and / or duration of the external influence. With the generated structure-borne noise, an energy form is then provided, which is fully or partially used by the extraction means for generating the electrical energy, thus enabling the electrical operation of the actuator and / or the activator.

Advantageously, if necessary, a structure-borne sound can be provided and used in such a way that is not or barely detectable by the human ear, which is not problematic for the user in that otherwise a structure-borne sound that is clearly audible to a person may be perceived as unpleasant.

Furthermore, it is advantageous that the extraction means are configured to use a body sound associated with the furniture body and / or the movably received furniture part for the generation of electrical energy. Thus, it is advantageously possible to use over all physically present areas of the furniture there existing structure-borne sound for generating electrical energy.

A further advantageous embodiment of the subject invention is characterized in that the extraction means are adapted to recover electrical energy from thermal energy. So you can in particular regularly occurring amounts of heat on furniture use, for example, due to sunlight on the furniture or in the environment or z. B. in kitchen furniture by heat generated during cooking. This is economically or ecologically advantageous.

Alternatively, it is also advantageous to obtain electrical energy from light energy. Light energy as well as thermal energy is usually at the sites of furniture regularly available, so that here an advantageous variant for the generation of electrical energy according to the invention is provided. For power generation z. B. may be provided a photovoltaic unit.

It is also advantageous that the extraction means are formed from an existing in the vicinity of the furniture body outside energy form, which is different from an electrical energy to gain electrical energy. Thus, for example, mechanical forces or sound or air flow effects, light and temperature can be used for the use of electrical energy. For example, forms of energy that can be used to enter into electrical energy by entering a room by persons in the floor or in walls of the room in which the furniture is located, which include impact sound and vibrations.

A further advantageous variant of the invention provides that the extraction means are designed to obtain electrical energy from an energy form present on or in the furniture body and / or the movable furniture part, which differs from an electrical energy. This makes it possible to use the energy forms that are not tied to the furniture itself.

It is also particularly advantageous to use the kinetic energy of moving in normal operation furniture part on the extraction means for obtaining the electrical energy. The movable furniture part is moved in normal operation via a technical drive unit, for example via an electric motor for driving the actuator, or a person or manually conditionally.

For example, a furniture drawer, which is moved out and inserted or a furniture flap, which is moved by swinging out and pivoting, provide the kinetic energy or provide energy derived from it. Also, a touch of the furniture body or the furniture part by a person from the outside and the associated vibration or pressure forces on the furniture can be used for energy.

In particular, it is advantageous that storage means for storing the electrical energy obtained by the extraction means are present. Thus, for example, a chargeable battery or a rechargeable battery or a capacitor can be provided in order to store electrical energy obtained with the extraction means and, in particular, to dispense it again with a time delay to a current consumer. The stored energy is used in particular for the electrical operation of the actuator and / or the activator or other current-operated device on the furniture.

However, the energy stored in the storage means can also be used for the operation of other energy consumers or electrical appliances.

This can be advantageously also larger amounts of energy or voltages provide, which is especially necessary for actuators for moving larger furniture parts or with higher loading.

Moreover, it is advantageous in phases in which the actuator or the activator does not require any electrical energy to store the electrical energy gained by the extraction means so that it is not lost.

Another essential aspect of the invention is that audio means are provided with which the operation of the actuator can be triggered depending on a structure-borne noise detectable in the furniture body and / or in the furniture part. In particular, it is advantageous that depending on a structure-borne noise, which is caused for example by an operating action from the outside, so for example, an action on the furniture by a person, the triggering of the actuator is possible. This represents a particularly elegant variant of a triggering action for the driven movement of the furniture part.

It is particularly advantageous that the audio means comprise sound elements which, depending on the operating action, generate a structure-borne noise in the furniture carcass and / or in the furniture part, which can be detected and processed by a control unit which controls the operation of the actuator. Thus, a structure-borne noise can advantageously be generated via the sound elements, via which the control units and thus the operation of the actuator can be triggered.

It is further proposed that, according to an advantageous variant of the invention, the control unit is designed to use a stored prescribable profile of structure-borne noise in the furniture carcass and / or in the furniture part for controlling the operation of the actuator. The profile is stored in particular in the control unit, for example in or on corresponding storage means. This is advantageously a comparison of a stored profile with a detectable profile possible what z. B. with the aid of a computing unit of the control unit, which in particular in accordance with the detected profile and a stored profile, wherein the match must move at least to a predeterminable degree, this is detected and the actuator is controlled or triggered. So it is advantageously possible to deliberately use predetermined actions from the outside on the furniture for the actuation of the actuator. The deposited profiles can z. B. be generated with a read-in process.

On the other hand, an accidental external impact on the furniture, for example, an unconscious or unwanted bumping the furniture, however, does not lead to a triggering of the actuator, which is desired. Because then no or not sufficiently high agreement between the deposited or deliberately given profile and the recorded profile is achieved due to the contagion. The corresponding control processes are advantageously controlled or implemented by the control unit.

Finally, it is also advantageous that the control unit is designed to detect an actual profile of a structure-borne noise existing in the furniture body and / or in the furniture part and / or subject the actuator to a comparison with a reference profile of structure-borne sound in the furniture body and / or stored in the control unit. or in the furniture part to control. Thus, the actuator and thus the movement of the furniture part can be controlled or controlled by specifiable reference profiles of a structure-borne sound very specifically.

This is advantageous in terms of a convenient and easy operation of the furniture.

Finally, the invention also relates to a piece of furniture with a device according to one of the above-mentioned embodiments.

In this way, the advantages explained in connection with the device according to the invention can be realized on a piece of furniture according to the invention.
