Description

State of the art

Drawers are known, comprising a device with a drawer rail and a switchable lighting device with a lamp unit.

The lighting device is used by means of the illuminant unit to produce a lighting effect in the drawer rail with artificial light. The lighting device is checked during operation by a lighting control device.

A side wall of the drawer as a drawer frame with an existing above a base part of the drawer rail, the z. B. has a translucent section, can be illuminated with lamps of the lamp unit. With the illuminants, the artificial light radiated into the side wall or drawer rail, with respect to the drawer, can laterally radiate inwards or outwards, so that, for example, an interior of the drawer can be illuminated.

To operate the lighting device, there is a supply of electrical energy to the lamps or a power supply.

Object and advantages of the invention

The object of the present invention is to provide a user-friendly and energy-saving, improved lighting situation in drawers oriented to practical use.

This task is solved by the independent claims.

In the dependent claims, advantageous and expedient developments of the invention are discussed.

The invention relates to a device consisting of a drawer rail, which can be assigned to a drawer, and a switchable lighting device, which comprises a lamp unit, with which a lighting effect in the drawer rail can be temporarily set up, the lighting device being a lighting control device for operational control of the lighting device, an energy store for supplying the lighting device with electrical energy and a sensor arrangement for detecting a movement state of the device and thus of the drawer when the device is present on the drawer, the lighting control device being designed as a function of the movement state detected by the sensor arrangement Device to switch the lighting device on or off, the sensor arrangement being able to accelerate and / or tilt and / or oscillate and / or with respect to the device to detect a shock and / or a state of shock and / or a change in position or distance. This allows the movement status of the device or the drawer to be detected very precisely and in all practical situations.

The sensor arrangement preferably comprises an acceleration sensor and / or a vibration sensor and / or a gyro sensor.

The state of movement of the drawer is identical to the state of movement of the device when the device is in the usable state or is present attached to the drawer. Accordingly, a detection of a movement state of the device is to be understood in the following to mean a detection of a movement state of the drawer, based on a use state of the device or in the case of a device according to the invention which is present on the drawer.

In the aforementioned manner, a desired lighting situation can be provided flexibly and reliably for a drawer, which comprises a drawer rail as part of the device according to the invention. In order to restrict the lighting or lighting effect to the desired operating states, different detection principles are advantageously or individually used, which are used for the controlled operation of the lighting device or for switching it on and off or for energizing and non-energizing. Accordingly, various sensor principles or sensors of modern detection technology are used. These have associated or specific advantages over other techniques. Common to all is the technically highly precise mode of operation, the high reliability, high economic efficiency and high robustness. In addition, the installation space required is comparatively small.

For example, an optical acceleration sensor, a piezoelectric sensor, a magnetic sensor, an inductive sensor and / or a capacitive sensor can be used as the acceleration sensor.

In the case of inductive sensors, the acceleration force acts on a mass, for example an iron core, which influences the inductances of the coil. The change in inductance is the measure of the acceleration.

In the case of magnetic sensors, an elastically suspended permanent magnet is used as the seismic mass, which changes its distance from an Hall element or a field plate resistor due to acceleration. The acceleration is determined by measuring the Hall voltage or the field plate resistance.

A capacitive acceleration sensor is preferably used, such as a so-called MEMS acceleration sensor (Micro-Electro-Mechanical-Systems acceleration sensor). A MEMS acceleration sensor consists of electronic logic and micromechanical structures, e.g. B. Silicon springs that are, for example, only a thousandth of a millimeter thick. The MEMS acceleration sensor which is suitable in each case can advantageously be selected from hundreds of components which are offered in a wide variety of price and / or performance categories. The developer defines the key parameters and features for the assessment and selection of the suitable MEMS acceleration sensor, which are essential for the respective application with regard to inclination and stabilization.

With a modern acceleration sensor, in particular an acceleration but also a position, an inclination, an oscillation or a shock, based on the drawer, can be measured. In the case of acceleration sensors with a seismic mass, it is advantageously possible to set up in all three spatial coordinates, with which a one, two or three-axis movement can be detected. A capacitive acceleration sensor is particularly advantageous for reasons of space and / or cost. When used for drawers, it is advantageous that the movement that is measured has to be detected in only one spatial axis, so that a uniaxial and thus comparatively simple acceleration sensor is sufficient to fully perceive the movement. Alternatively, however, multi-type sensors can also be used. In the case of capacitive acceleration sensors, a change in capacitance on the inside can be measured on one or two sides. A one-sided or a uniaxial capacitive acceleration sensor can advantageously be used to detect an opening movement of the drawer. This assumes that this is not detected when the drawer is closed, which means that when the drawer is closed, e.g. B. with a retraction arrangement in a closed state this movement is damped, since undamped braking can be understood as negative acceleration by the measuring system. Otherwise an additional sensor system would be necessary to make a distinction between an opening movement and a closing movement of the drawer.

A vibration sensor is used to detect movements and / or vibrations using a gold-plated, movable microsphere. Due to its small dimensions, a vibration sensor is advantageously suitable for use in comparatively very small electronic devices. The vibration sensor is advantageously very easy to integrate and requires no special signal evaluation. The microsphere with a small diameter, for example generally less than 1 millimeter, is located in a cavity of the sensor and can move freely within it. The slightest movements or vibrations set the ball in motion so that it closes or opens two gold-plated contacts. The resulting impulses are evaluated in application-specific electronics and converted into corresponding switching commands.

A gyro sensor or a gyroscope sensor measures a rotational speed or a rotary movement. The gyro sensor uses the Coriolis force and the so-called tuning fork principle to determine the position of the object to be detected. In the gyro sensor, metal elements are made to vibrate by electricity. When the gyro sensor moves, the vibration of the metal elements changes and the capacitors arranged around them register the corresponding change.

The lighting control device preferably comprises an intelligent unit or a computer unit, for example electronic elements implemented on a circuit board. This enables a space-saving and / or a flexible or, alternatively, possible attachment from different locations. The lighting control device is preferably programmable or preferably comprises a controller or a programmable controller. The lighting control device and / or the sensor arrangement is or are preferably designed such that the lighting control device and the sensor arrangement communicate with one another at least temporarily. The light generation with the lighting device serves to provide artificial light in or in the vicinity of the drawer rail. To generate light, the lighting device generally comprises an artificial light source formed from several identical light means, preferably a light-emitting diode arrangement or LED arrangement with several LEDs and / or other light source arrangements.

The drawer rail, which consists entirely or in sections of a transparent or translucent material, and not another element of the drawer, is used as the object for coupling the lighting effect to the drawer.
As a rule, there is an identical drawer rail on both side walls of the drawer available. This enables the drawer to be illuminated in the same way, evenly or symmetrically. The drawer rail also advantageously extends generally over the essential or overall depth dimension or length of the drawer and in particular borders directly on the interior or storage space of the drawer to be illuminated, which enables an effective lighting effect and use of light.

The energy store preferably provides a low-voltage voltage, preferably a low-voltage working voltage of less than 50 volts, preferably less than 10 volts, preferably an electrical voltage of 5 volts. The energy store is preferably designed as a structural unit closed to the outside with a closed outer surface, apart from one or more plug-in points and / or connection points. The unit is compact z. B. in flat or plate construction with a robust outer housing, for example made of a hard plastic to protect the inside of the energy store against outside penetration of moisture and / or dirt. The unit has, for example, approximately the format of a commercially available smartphone or a power bank. The energy storage can, for. B. be designed specifically or based on a commercially available power bank or on a commercially available mobile battery.

The energy store or a corresponding rechargeable battery is advantageously received or adjusted on a rear wall holder of the drawer. This is preferably done via a tool-free assembly, for example by magnetic attachment or by a Velcro connection. The energy store is preferably attached to a section against, for example, the rear of the drawer or a drawer rear wall or a rear wall holder by a mechanical connection. A mechanical connection according to the keyhole principle is preferred. In this case, the energy store is brought up to be attached to a counter section, such as a rear wall holder, until a connecting or latching element on the outside of the housing of the energy store can dip into a keyhole on the counter section or on the rear wall holder. With a subsequent downward movement of the energy store, the energy store slides into a narrower guideway or into an elongated hole below the keyhole until the latching element reaches an abutment or a stop at the lower end of the guideway. In this final assembly position of the energy store, a securing is preferably implemented by a spring element, which in the final position reached snaps into a latching position, whereby an upward movement of the energy store is blocked. To remove the energy storage device or to detach its housing, the spring element is operated without tools or with a tool such as a screwdriver and the detent set up until then is released, which then enables the energy storage device to move upwards since the catch is unlocked.

The lighting control device is advantageously designed to set up or prevent the supply of the lighting device with electrical energy, depending on the state of motion of the device detected by the sensor arrangement. A basic physical principle is thus used for the safe operation of the lighting device.

In addition, in practice, a desired lighting effect for the user of the drawer is generally dependent on the usage state of the drawer and thus generally on the type of the prevailing state of motion. A state of motion also includes a standstill situation, i.e. when the drawer is not z. B. moved over a drawer slide with a full or partial extension arrangement relative to a furniture body of a piece of furniture.

The lighting control device preferably comprises a switching arrangement or a switch, so that the supply of the lighting device with electrical energy or with electrical current can be set up or prevented in a targeted manner by the switch assuming a corresponding open or closed switching state. The switching state can be controlled with the lighting control device.

It is also advantageous if the lighting control device is designed to switch on the lighting device when the device is in a state of motion detected by the sensor arrangement when the device is moving in a first direction of movement. Depending on the wishes of the user, a direction of movement can thus be specified in which the lighting effect exists or that there is no lighting effect when the device and thus the drawer move opposite to the first direction of movement. It is preferably specified that the first direction of movement corresponds to an opening direction of the drawer relative to the furniture body. The control device is preferably designed such that, when the device is in use, the lighting device is activated or switched on when the drawer is opened. Conversely, it is possible with the control device that the lighting device is not activated or switched off when the drawer is closed. Overall, this is user-friendly or reduces the operating time the lighting device to an application-specific minimized dimension. In particular, when opening the drawer, it is particularly useful or helpful if you can already visually grasp the storage space of the drawer during the opening movement by switching on the lighting device and creating a lighting effect in the drawer rail, which also affects the vicinity of the drawer or illuminates their storage space. Due to a transparent or translucent drawer rail, light shines from the rail into the drawer. This is particularly advantageous if the area around the drawer is not well lit or is in the dark. With the lighting device specifically switched on at least when opening, the storage space is brightly illuminated at least when opening and is thus already clearly visible to the user. The user is then in real time or immediately after the end of the opening movement in the picture of which objects and / or at which point these are housed in the drawer. Even while the drawer is opening, the objects accommodated in the storage space of the drawer are clearly recognizable, which is advantageous for the subsequent removal of items from the drawer. When closing the drawer, the storage space is generally of no interest to the user. Therefore, the targeted detection of the opening movement with the sensor arrangement and the associated lighting of the drawer rail is only advantageous when opening. Energy consumption when closing for lighting is advantageously excluded for economic and / or ecological reasons.

Another modification of the invention can be seen in the fact that the lighting control device is designed to switch on the lighting device after a movement state of the device detected by the sensor arrangement, when the device moves in a first direction of movement, and the lighting device after a predefinable period of time has elapsed switch off from a reference time. In this way, coupled to the opening movement and tailored to practice, the lighting device, which is switched on or switched on when the movement is detected, is only switched on for as long as necessary or sensible. An undesired or unnecessarily permanent switching state “switched on” as far as the lighting device is concerned is avoided.

According to a further modification of the invention, the lighting control device is designed to set the reference point in time to the point at which the standstill position is reached after the device has been moved in the first direction of movement.
This affects e.g. B. the drawer movement relative to the furniture body, wherein the reaching of a standstill position of the drawer is detectable and the lighting device is switched off after a predetermined period of time after reaching the standstill position. The first direction of movement of the drawer relative to the furniture body is preferably an opening direction of the drawer. At the end of the opening movement, this means that what the sensor arrangement detects and a corresponding signal is sent to the lighting control device, a predeterminable time period expires, within which the lighting effect of the connected lighting device continues to exist or is safe. After the period of time that can be variably specified or adapted, the lighting device is then switched off. Preferably, the lighting device is switched on before reaching the standstill position, preferably during the entire opening movement of the drawer, ie with the start of the movement from the previously taken z. B. closed standstill position, and remains after reaching the open standstill position until the predeterminable time period has expired.

However, it is not excluded that when the standstill position is reached or shortly before, the lighting device is only switched on and when the standstill position is reached the predefinable time period expires or is switched off again after the time period has expired.

The predeterminable period of time can e.g. B. a few seconds up to 20 or more seconds. The time period is, for example, 2, 3, 5 or 10 seconds or more. The time setting is advantageous with regard to the practical use of the drawer. With the experience-based predetermined period of time, the lighting effect after the end of the opening of the drawer, the drawer at the end of the opening reaching a partially or completely open standstill position on the furniture, is specifically still activated or the lighting device is still switched on. After the period of time that begins when the opening movement ends, the lighting device is automatically switched off. The user does not have to think about switching off or does not have to actively switch off the lighting himself. In particular, the lighting can be operated in such a way that the lighting switches on automatically or automatically and only remains switched on during an actual or experience-based period of use of the drawer, for example while a person is taking something out of the drawer or placing an object in the drawer. Accidental prolonged energy consumption is advantageously avoided.

The predeterminable time period is preferably a timing element, which acts as a passive timing element is implemented. The predeterminable period of time can preferably be set up without connection to an external power source. This enables, in particular, an energy-self-sufficient function of the timing element or a time span operation with the energy store alone.

The timer is particularly needed to switch off the light after a certain time. As a rule, this is achieved in electrical engineering with an IC timer module. This is an active component, which is dependent on an external power source and which can be controlled via a microcontroller and variably set by the software. A passive timer has the advantage that it does not require a connection to an external power source to implement the desired function. For this purpose, this function is dimensioned once and is then permanently parameterized or, if necessary, adjustable via a potentiometer.

Associated components can be integrated on the light bar or an LED bar. An external board is then not necessary, on which the microcontroller would then also be positioned.

It is also advantageous if the lighting control device is designed to detect a movement of the device in a second movement direction that can be detected by the sensor arrangement and to bring the lighting device into a switched-off state and / or in during the movement of the device in the second movement direction left in a switched off state.

The first and the second direction of movement preferably run along the same spatial axis, the first and the second direction of movement being opposite to one another.
The second direction of movement preferably corresponds to the closing direction of the drawer relative to the furniture body. At least from the time of the start of the movement in the second movement direction and during the preferably entire movement of the device or the drawer in the second movement direction, which the sensor arrangement recognizes and a corresponding signal is received by the lighting control device, it is ensured that the lighting effect of the Lighting device does not exist or the lighting device is switched off and also preferably remains switched off for the entire duration of the closing movement.

According to an advantageous modification of the invention, the energy store is designed as a structural unit which has a connection point for a plug connection with an electrical line. The energy storage device can thus be used in a user-friendly manner. The connection on the energy store in order to connect it to an electrical line is used to supply energy to the lighting device or the light sources of the illuminant unit and / or to charge a rechargeable storage unit of the energy store for storing electrical energy. For example, the energy store preferably has an opening on its outside, which belongs to the attachment point on the energy store. The plug-in point preferably comprises a plug-in section which is countersunk to an outside of the housing or recessed inwards and on which a plug of the electrical line can be brought into conductive plug contact with friction. In particular, the energy store can optionally be electrically or galvanically connected to the lighting device and / or an energy supply from the outside and physically separated, which is possible with a simple handle or without aids.

The attachment point on the energy store and the matching connector are preferably designed in accordance with a commercially available or standardized connector arrangement, which is economically advantageous. The connector assembly can, for. B. according to a Micro USB-B port or according to a Micro USB-C port. By plugging in the plug at the end of the electrical line, for example an electrical cable, it is quick and easy for the user to set up the conductive connection and to remove it by pulling the plug out of the connection point.
This allows the energy storage device to be connected in a conductive manner to supply the consumer or to charge the storage unit, and to mount and / or remove it, for. B. on the back of a drawer.

There are preferably several or exactly two attachment points on the energy store. A first attachment point and a second attachment point are e.g. B. identical or different. Preferably, both plug-in points are present on the same, for example, narrow side or flat side of a housing of the energy store, for example a few centimeters apart. The first plug-in point is used, for example, to supply energy to the lighting device or the illuminant unit with stored energy from the storage unit of the energy store, which takes place via a first electrical line. The second plug-in point is used, for example, for the electrical connection of the energy store via another electrical line to an external energy source for the electrical charging of the storage unit of the energy store, for example for charging via an external power supply via a socket connection at the other end of the electrical line or via a power network or a power bank or another Battery pack. With a comparatively long cable as an electrical line, the energy storage device for charging does not need to be removed from the drawer.
Alternatively or alternatively, the charging of the storage unit of the energy store via z. B. a power bank at a 5 volt input via USB-B or USB-C port.

Alternatively, the energy store and / or at least the storage unit can be removed from the drawer for charging. Removing the energy storage from the drawer or a drawer back or z. B. a corner post or a corner connector in a rear corner area of the drawer between the side wall or the rail and the back of the drawer can be done, for example, with a simple screwdriver or without tools. If the storage unit is removable, it can be connected in a conductively detachable manner to a basic unit of the energy store, so that the lighting device can be supplied with energy from the charged storage unit when connected.

It is also advantageous that the illuminant unit has an attachment point for a plug connection with an electrical line. This means that the energy supply to the lamp unit is flexible and easy with a z. B. Cable line can be set up with a suitable plug for the connection point of the lamp unit.

A preferred variant can be seen in the fact that an electrical line is provided between the energy store and the lamp unit, which can be plugged into the energy store and / or the lamp unit. Since the energy storage device can advantageously be arranged on the drawer itself, a cable connection of the lamp unit to an energy supply present outside the drawer is therefore not necessary, with the resultant disadvantages, in particular due to the displaceably moving drawer relative to the furniture body, being avoidable, e.g. B. by jamming on a drawer rail or on the furniture body or hooking line or cable sections of the electrical line. As an alternative to the plug connection, a fixed line or cable connection is possible on the energy store and / or on the lamp unit. With the z. B. plug connection on the lamp unit, the plugged-in line being electrically connected to the energy store, for example with a further plug or another plug connection at the other end of the line, the energy supply to the lamp unit is advantageously possible. The z. B. designed as a flexible cable for the electrical connection can save space and shape z. B. be snug on wall sections of the drawer. With the z. B. each connected to the illuminant unit and the energy store connected line, the distance between the attachment point on the energy store and the attachment point on the illuminant unit can be bridged flexibly and in a space-saving manner.

An advantage results from the fact that the illuminant unit is designed as a light bar with a light-emitting diode arrangement. This is compact and easy to assemble.

It is also advantageous that a control unit for the control with the lighting control device is provided, which is integrated in a housing of the energy store. The lighting control device can thus be accommodated in a protected manner in an already mandatory part of the device.

It is also advantageous if a control unit for control with the lighting control device is provided, which is integrated in the illuminant unit. An already existing component of the device is thus used for the integrated accommodation of the control unit.

The energy store is advantageously designed as a plug-on component for detachable attachment to a counter section. The counter section, which is present, for example, on the device or on parts of the remaining drawer, such as a corner connector or a rear wall holder, is a suitable slot. The slot on the counter-section and a plug-in section on the energy store are matched to one another in such a way that the energy store can be detachably attached or plugged in with a simple handle or manually on the counter section and can therefore be attached in a fixed position.

Preferably, on the preferably at least substantially cuboidal energy store or on a housing, preferably on a common narrow side of the cuboidal energy store component, a plurality of preferably exactly two projecting plug sections are provided on the outside. The plug-in sections are preferably identical and are spaced apart from one another on a line parallel to a component edge of the energy storage component. For example, two or more nail-shaped plug-in sections are formed on the energy store with a narrow elongate shaft and at the free end with a head larger in diameter than the shaft. As a slot for such a plug-in section, a keyhole-shaped recess or a keyhole with an opening designed for inserting the head is provided on the counter-section to match a nail-shaped plug-in section is slightly larger in outer dimension or diameter than an outer dimension or diameter of the head. At the bottom, in relation to a usable state, there is an elongated hole with a constant width that is slightly larger than the width or a diameter of the shaft of the plug-in section. So the energy storage with z. B. two nail-shaped plug-in sections projecting from it on the housing can be suspended in, for example, two vertically superimposed recesses on the counter-section. When inserting, the head grips vertically through the openings, with the energy store being held in a self-locking manner on the counter section when the energy store slides down on the counter section. The respective shaft sits on the bottom of the elongated hole. The part of the head protruding from the shaft engages behind the elongated hole, so that the energy store cannot be moved against the plugging direction and downwards. In this attachment situation, an automatically locking mechanism is preferably set up via spring locking means acting on the shaft. To remove the energy store, after releasing the latching, for example with a screwdriver, the energy store must be displaced somewhat vertically upwards and then moved away in the direction in which the head was inserted through the opening. Both plug-in sections come free from the respective recess on the counter section at the same time.

The invention also relates to a drawer with a device according to one of the configurations described above. This allows the drawer's advantages to be realized.

Preferably, the drawer rail of the device or the drawer as a hollow profile element, for. B. placed on a lower frame part or a lower side, front or rear wall element of the drawer.

The drawer rail is preferably present as a cross rail on a front or rear of the drawer and / or as a longitudinal rail on a side wall of the drawer.

The invention also extends to a piece of furniture with a furniture body and a drawer which has a device which is designed in accordance with one of the modifications described above.

The drawer is preferably movably or displaceably received on the furniture or a furniture body of the furniture via a rail guide arrangement. The rail guide arrangement preferably comprises two full pull-outs per drawer, each with a body rail, middle rail and drawer rail, which are connected to one another in a longitudinally displaceable manner. As an alternative to the full pull-outs, partial pull-outs can be provided, each with a cabinet rail and drawer rail.

On the energy storage 17th , 32 , 33 and 34 is a point of attachment 35 for connecting a suitable plug (not shown) to a charging cable for electrically charging those in the respective energy store 17th , 32 , 33 and 34 existing storage unit, which can be electrically charged with an external power supply, for example a power grid or a power bank, when the plug is connected to the charging cable.

On the outside of a housing of the at least substantially cuboidal energy storage 17th or on a lateral vertical narrow side of the energy store 17th are several protruding plug-in sections 36 available, preferably several, for example exactly two plug-in sections 36 . The plug-in sections 36 are preferably identical and mutually on a line parallel to a component edge of the energy store 17th spaced apart. For example, are on energy storage 17th two nail-shaped plug-in sections 36 with a narrow elongated shaft 37 and at the free end with one to the shaft 37 larger diameter head 38 educated. As a slot 39 for such a plug section 36 is on one of the metal strips 25th formed counter section to the nail-shaped plug-in sections 36 matching keyhole-shaped recess 40 with one for inserting the head 38 trained opening 41 , which is slightly larger in outer dimension or diameter than an outer dimension or diameter of the head 38 . At the opening 41 an elongated hole closes at the bottom in relation to a state of use 42 with a constant width that is slightly larger than the width or a diameter of the shaft 37 . So the energy storage with z. B. two nail-shaped plug-in sections projecting from it on the housing in, for example, two vertically superimposed recesses 40 on the counter section or the metal strip 25th be hung, with the respective head 38 through the corresponding opening 41 grips vertically and the energy storage device slides down 17th is held self-locking on the counter section. The respective shaft sits 37 at the bottom of the slot 42 on. The one to the shaft 37 protruding part of the head 38 engages behind the elongated hole 42 so the energy storage 17th against the direction of insertion and down is not movable. To remove the energy storage 17th it has to be shifted slightly vertically upwards and then against the direction in which the head 38 through the opening 41 was inserted, moved. Both plug-in sections 36 come simultaneously from the respective recess 40 on the counter section or sheet metal strip 25th free.

A possible resilient locking and releasable locking of the plug-in sections 36 on the recesses 40 is not realized in the exemplary embodiments shown.
