Description

The present invention relates to a barber chair according to claim 1, two methods for evaluating an occupancy state of a barber chair according to claim 11 or 12 and a barber shop according to claim 17.

Barber chairs of the type in question serve to accommodate a person (generally a customer) during a hair treatment, in particular the treatment of the head hair of the person, especially the care of the head hair and the design of the hairstyle of the person. Typically, this treatment is performed by a specialist in hair treatments, especially a hairdresser, a hairstylist or a hair stylist or the like. The treatment of the head hair of a person includes, inter alia, cutting, blow-drying, dyeing, tinting, styling and attaching hair extensions. In part, barber chairs are also used to treat eyebrows, eyelashes and / or a beard. In part, such barber chairs are also used to wash the hair on a barber wash.

A barber chair of the type in question is usually rotatable, tiltable and / or movable, in particular rollable. Usually, a barber chair has a seat with a seat, a backrest, two side armrests and a footboard. The foot can z. B. have a pedestal and a base with rollers.

It is typical for a barber chair that it is adjustable in height, even while the person to be treated occupies the barber chair, in particular sitting on it. Often a height adjustment is realized by means of a hydraulic lifting device. Of course, the lifting device also allows a lowering of the barber chair. A hydraulic lifting device is usually adjusted by means of a lever, wherein the lever is usually operated by a foot.

A generic barber chair is from the US 4,372,605 A and from the DE 10 2008 018 654 A1 known. The known barber chairs have a seat, a backrest, two side armrests, a footboard and a mechanically or electrically driven lifting device for height adjustment of the barber chair on.

From the DE 10 2006 030 193 A1 an aircraft seat with a seat monitoring unit for determining a seated state of the aircraft seat is known. The seat monitoring device has a sensor element which can measure physical data by means of which information about the seated state can be determined. Physical data may be, for example, weight data, photo data, image data, temperature data and light data.

From the CN204015734 U For example, a system for controlling a light source is known. The system is built into a chair and includes sensors and a light source switch that are interconnected. By means of the sensors, an occupancy state of the chair can be determined. Depending on the occupancy state, the light source can be turned on and off by means of the light source switch.

From the DE 11 2008 001 814 T5 is known a vehicle seat, the occupancy state can be detected by means of an occupant detection system with vibration sensors.

From the DE 102 23 365 A1 is a vehicle seat with a sensor known. With the sensor can be detected when a pregnant person occupies the vehicle seat.

From the DE 10 2011 113 100 A1 For example, a vehicle seat with a ballistographic sensor for detecting ballistocardiogenic and / or respiratory movements of a person is known.

From the EP 1 015 279 B1 a device for detecting a occupancy state of a vehicle seat is known. This device comprises means for distance determination.

From the DE 602 03 179 T2 For example, a seating device with sensors for sensing the positions of limbs of a human body is known. The sensors may include a pressure sensor, a temperature sensor, a non-contact sensor for measuring the pulse or heart rate or a camera.

Typically, hairdressing chairs of the type in question are used in a hairdressing salon. In the environment of a barber chair, especially in a hairdressing salon with a barber chair, there are numerous processes that can or must be designed differently depending on whether a person occupies the barber chair (that is, sits on it) or not.

So it is z. For example, it would be desirable to radiate light having a low color temperature (so-called "warm light") in a hairdressing salon to provide a pleasant and comfortable atmosphere. Warm light, however, is inappropriate during the treatment of a person's hair, since it does not reflect the typical daylight conditions (usually with a high color temperature, ie "cold light") and thus too can lead to a distorted subjective impression. Accordingly, it is advantageous to control the emitted in the vicinity of the barber chair light so that when sitting down a person (a customer) on the barber chair from basically radiated warm light in cold light is changed. Preferably, this color temperature change takes place automatically.

It may also be desirable to turn on light sources in the immediate vicinity of the barber chair only when a customer occupies the barber chair, and then turn it off again as soon as the customer gets up again. In this way, a considerable amount of energy can be saved.

In order to be able to design processes dependent on the occupation of the hairdressing chair as comfortably and efficiently as possible, it is advantageous if the occupancy of the hairdressing chair is detected automatically and these processes are carried out automatically depending on the occupancy state.

The object of the present invention is therefore to provide a barber chair, suitable methods and a hairdressing salon, which allow the automatic implementation of processes, the configuration of which depends on the occupancy of a barber chair by a person.

According to a first aspect of the invention, the previously described task is solved by the barber chair according to claim 1. Preferred embodiments of this aspect of the invention are the subject of the relevant subclaims.

It goes without saying that embodiments, embodiments, advantages and the like, which are given below for the purpose of avoiding repetition only as an aspect of the invention, apply correspondingly in relation to the other aspects of the invention.

Having said that, the present invention will be described in more detail below.

The basic idea of the first aspect of the invention is to provide the hairdressing chair with at least one sensor for the qualitative and / or quantitative detection of a physical measured variable, which index a occupation of the hairdressing chair by a person. A suitable physical measure is z. As a caused by the person pressure on the barber chair, caused by the person temperature change, the distance of the person to the barber chair, a pulse rate of the person, a respiratory rate of the person and caused by the person changing a light beam.

A caused by the person change of a light beam can be z. B. by means of a light barrier with a photodetector, such as a photodiode, a phototransistor or a photoresistor detect.

The hairdressing chair according to the invention allows automated detection of occupancy of the barber chair by a person. In particular, can be determined automatically with the help of the hairdressing chair according to the invention, when a person sits down on the barber chair or gets up from the barber chair again.

The measurement data of the sensor can be z. B. evaluate automatically using electronic circuits and perform a control or data processing. In this way, dependent on the occupation of the hairdressing chair processes can be automated.

The hairdressing chair according to the invention has at least one reading unit which is designed to read out a person identifying identifier of a transponder. For this purpose, a reading unit corresponding to an RFID transponder is particularly suitable, which can establish a coupling with the RFID transponder by means of magnetic alternating fields and / or high-frequency radio waves. Preferably, the reading device is designed for data processing by means of a microprogram and a middleware with an interface to other electronic circuits.

With the aid of a system consisting of the reading unit of the barber chair and an RFID transponder, objects and persons can be identified and located automatically and without contact. An RFID transponder corresponding to the reading unit of the barber chair can e.g. B. in a person handed over the object, such. As a bracelet or a form to fill out by the hairdresser or the hairdresser form, housed. The RFID transponder can then be provided with a predetermined identifier before being handed over to the person. If the person is finally in the vicinity of the barber chair, this identifier can be read out and further processed or evaluated with the aid of the reading unit. The read identifier allows on the one hand the identification of the person and on the other hand their localization. This information can be used for personal processes.

Preferably, the sensor of the barber chair is designed as a piezoelectric pressure sensor. Piezoelectric pressure sensors are based on the piezoelectric effect and are known from the prior art. Such sensors detect changes in the pressure applied to the sensors, wherein due to the pressure change electrical charges are generated.

It is advantageous if the piezoelectric pressure sensor is designed to qualitatively detect a change in the pressure on the hairdressing chair caused by the person. With such a sensor can be detected when a person occupies the barber chair, in particular sits down on the barber chair, and when a person stands up from the barber chair.

According to a preferred embodiment of the barber chair, the sensor is integrated in the barber chair, in particular in a seat, a backrest, an armrest and / or a foot part of the barber chair. This embodiment is useful for the function of the sensor. On the other hand, this embodiment creates a pleasing impression, since the sensor is not visible to the person during operation.

The term "seat", as used in the present invention, refers to the area of the barber chair, which is at least mainly intended to serve as a seat, that is designed so that the person can sit on it. The seat may be upholstered and / or one or more cushions and / or seat cushions may be disposed on the seat.

It has proved advantageous if the hairdressing chair is designed to process a signal generated by the sensor and / or the reading unit. These include typical methods of signal processing, such as. As amplification, conversion, coding and / or packaging, but also an evaluation. For such purposes z. B. a signal processor can be used.

The barber chair may include a data processing unit that may include the aforementioned signal processor. The data processing unit of the barber chair is designed to determine an occupancy state of the barber chair on the basis of the signal generated by the sensor and to generate a busy state signal.

The term "occupying state", as used in the context of the present invention, denotes the state of occupancy of the barber chair. In the simplest form there are exactly two occupancy states, namely the occupancy state "occupied" and the occupancy state "unoccupied", wherein a transition is only possible from one to the other occupancy state. In addition, the occupancy state may include an indication of the elapsed time since the last state change. So the occupancy state z. B. assume the value "occupied for 5 minutes". The occupancy state can also understand further evaluations, such. B. "just got up and sat down again".

When creating the occupancy state signal, the data processing unit of the barber chair brings the specific occupancy state into waveform. Thus, the occupancy state signal transports the occupancy state.

Typically, therefore, an output signal originating from the sensor is not evaluated directly and not by the sensor itself for determining an occupancy state of the barber chair. Rather, signal processing of the output signal of the sensor and forwarding of the processed signal to the data processing unit takes place first. The data processing unit evaluates the processed signal and then determines an occupancy state of the barber chair based on the signal generated by the sensor. The data processing unit then creates an occupancy status signal which can be forwarded to further electronic circuits of the hairdressing chair.

The determination of a state of occupancy of the barber chair is only optional through the barber chair. It is also possible to have this determination of a state of occupancy of the barber chair made by a device outside the barber chair. In this case, the information contained in the output signal of the sensor is transmitted to the physical measured variable after signal processing to this device outside the barber chair.

The barber chair preferably has at least one transmitting unit which is designed to receive a signal generated by the sensor and / or the reading unit and processed by the barber chair and / or an occupancy state signal of the data processing unit and for the wireless transmission of a signal.

With the aid of the transmission unit, signals can be transmitted wirelessly to a reception unit outside the hairdressing chair, without the need for a cable between the transmission unit of the hairdressing chair and the reception unit outside the hairdressing chair. This ensures mobility and comfortable handling of the barber chair. It also ensures a better visual impression.

When transmitting a wireless signal to the receiving unit, it should be noted that the receiving unit is typically located less than 100 m away from the hairdressing chair's transmitting unit. The transmission from the hairdresser's transmitter unit to the receiver unit typically takes place within a building, occasionally held within a room. It is important a robust and reliable transmission even without direct line of sight, so that the wireless signal can be received correctly by the receiving unit. Basically WPAN and WLAN technologies come into question as wireless technology. Bluetooth is preferably used as the wireless technology. Due to the energy-saving Bluetooth version 4.0 (Low Energy) is particularly preferred.

Preferably, the transmitting unit of the hairdressing chair is for wirelessly transmitting a signal generated by the sensor and processed by the hairdressing chair, an occupancy state signal of the data processing unit, an identifier read and processed by the reading unit, an address of the hairdressing chair, an error code and / or information about the state of an energy store the barber chair trained.

Using an error code, the receiving unit can be notified of errors that have occurred in components of the barber chair. So an error code z. B. transport the information that the sensor of the barber chair is defective, that a measurement error has occurred and / or that the occupancy state is currently indeterminate.

The energy storage of the barber chair can one, several or all electronic circuits of the barber chair, such. B. the reading unit, the data processing unit and the transmitting unit to provide energy. As an energy storage batteries are preferably used, which are advantageously rechargeable.

The wireless transmission typically occurs with the aid of individual data packets, whereby a data packet can also contain only a part of the aforementioned information.

Preferably, the barber chair has a plurality of sensors, wherein at least two of the sensors are designed to detect a different physical measured variable. So the barber chair z. B. have three sensors, wherein two sensors for detecting a pressure caused by the person on the hairdressing chair and a sensor for detecting a person caused by the change of a light beam are formed. In this way, the barber chair can detect and correlate different physical measures that indicate occupancy of the barber chair by a person, so that an occupancy state of the barber chair can be more reliably determined. Preferably, then, the transmitting unit of the barber chair is designed to receive a signal generated by the respective sensor and processed by the barber chair.

In a preferred embodiment of the hairdressing chair according to the invention, the hairdressing chair has at least one remote control for controlling an external device, in particular a device for reproducing image and / or audio data. In the external device, it may, for. For example, a television, a radio, a DVD player, a Blu-ray player, a computer, a tablet or a game console. With the help of the remote control, the occupant of the hairdresser's chair can even operate the external device wirelessly.

Another aspect of the present invention is the use of a sensor for a barber chair for the qualitative and / or quantitative detection of a physical parameter that indicates occupancy of the barber chair by a person. In particular, the physical measure may again be a pressure on the barber chair caused by the person, a temperature change caused by the person, the distance of the person to the barber chair, a pulse rate of the person, a respiratory rate of the person and / or a change in a light beam caused by the person be.

In a preferred embodiment of the use, the sensor is integrated in the barber chair and / or the sensor is designed as a preferably piezoelectric pressure sensor. Advantageously, a signal generated by the sensor and processed by the hairdressing chair is received by a transmitting unit of the hairdressing chair and further processed and the further processed signal is transmitted wirelessly by means of the transmitting unit to a receiving unit.

Preferably, the sensor is formed as it has been explained above as the hairdressing chair according to the invention as such.
