Description

The Invention relates to an opening and locking system, especially for furniture components such as drawers, doors, Revolving, swivel and sliding doors, Flaps, etc., according to the preamble of the protection claim 1.

Opening systems for furniture parts are already known from the prior art in the form of touch-latch systems, such as in the DE 101 57 754 A1 disclosed. Such touch-latch systems have the disadvantage that they must have an undesirable front gap of at least about 5 mm, so that the opening mechanism can be actuated by pressure on the furniture front. This front gap of about 5 mm is undesirable because it is on the one hand visually disturbing and on the other can lead to contamination in the interior of the furniture part, or an additional seal between the furniture front and the furniture body to prevent contamination must be provided, resulting in additional Costs leads. Such a seal must be provided for example in the prior art, if the furniture part has a cooling and / or warming function, such as a refrigerator or an electric cooker.

With the DE 20 2004 007 168 U1 is already an ejector for a movable furniture part, in particular door or drawer, disclosed with a pusher and an electric drive unit for this shock device, wherein the drive unit by pulling and / or pressure on the shock device on the furniture front, namely the door or drawer , is triggerable.

By this train or pressure on the furniture front, especially the door or the drawer front, for example, becomes a proximity sensor inside the furniture body activated, which sends a signal to the engine designed as electric Drive unit for the jar is, so that this jar from the Ejector is ejected in the direction of furniture door and this Furniture door then opens automatically. Of the contactless Proximity sensor therefore responds to a manually caused tensile or pressure exertion anywhere on the closed door and activates the ejector. This is of course in the Case of pressure even in the closed end position of the door a little play for the by the pressure exercise movement of the door in the direction of the ejector caused by the user, so in the closing direction, intended. If the movable furniture part is a drawer, The ejector can be placed on the back of the drawer or on the back on a protruding Part of the front panel of the drawer act. Furthermore, instead of of the electric motor as a drive unit for the thrust device of Exhaust also be provided a solenoid (solenoid), the however in its further execution and Arrangement is not further disclosed. Furthermore, it is envisaged that the drive unit arranged by a in the ejector Power storage, preferably battery, can be supplied with power. In addition to this can be a damping function, d. H. a dissipation (energy conversion) of the kinetic residual energy the door near its closed end position, be effected.

Disadvantage of this opening device of DE 20 2004 007 168 U1 is that the thrust device of the ejector is designed as a relatively complicated trained, multi-telescopic sleeve part, and also an electrical control of the electric motor by means of four position sensors (LED's) is provided, which leads to increased electrical circuitry and software costs. Furthermore, it is disadvantageous that the motor must also be actuated when closing the door or the drawer, so that from this an increased energy consumption, as well as increased wear of the engine follows.

Overall, with the DE 20 2004 007 168 U1 So a relatively complicated and costly trained opening device disclosed.

With the DE 296 21 527 U1 a refrigerator and / or freezer is disclosed with a door for closing the refrigerator and / or freezer compartment, wherein a trigger element and a means for opening the door are provided, and after the actuation of the trigger element, the door opens automatically.

Of the Ejector for the refrigerator door is through exerting pressure on the door triggered, wherein the shock device can be driven by an electric motor can. This electric motor can in turn via a voice recognition circuit be controlled, for example, by a voice command "door open" is again designed as a multiply telescoping sleeve device, whose individual parts are sealed to each other. In the closed Condition is the refrigerator door through a locking means device in the form of a spring-loaded ball, which engages in a corresponding recess equipped. This Locking means itself, however, can not be released and locked by means of motor power. Disadvantage of this design Again, that is relatively constructive and with regard to Cost is elaborate, in which case in addition a Seal the parts of the telescopic ejection added to each other.

The JP 2003003746 discloses a similar opening device for a door, as the former DE 20 2004 007 168 U1 , here as well Sensors for controlling the motor are present.

Of the Engine drives after touching a touch sensor a fixed spindle on which a nut in a sleeve-shaped ejector against The force of a spring is longitudinally displaced being, being the ejector is guided in a guide sleeve and at the opening Door supported. The mother is now promoted so long by means of motor against the spring until this has built a predefined spring tension, which is for a sudden opening of the Door is necessary. This makes it possible that a relatively slow and low powered engine its energy stores in the spring, and then this energy abruptly with relatively higher Power and higher Speed to the opening Door delivered becomes. The ejector can move forward through the engine and moves backwards become. The disadvantage here again is the relatively complex and cost-intensive design with a spindle, a rotationally driven and over Position sensors controlled motor. Another disadvantage is that the engine has a high energy consumption because of the engine Spring tensioned before opening the door must be and also the return the ejector into its starting position also by the engine. A Storage of kinetic energy when closing the door by the user is not provided.

task It is therefore an object of the present invention to provide an opening and closing system, especially for Furniture parts, according to the prior art in such a way that this essential easier and cheaper in design, manufacture, assembly, repair, maintenance and operation is.

to solution the tasks set serve the features of the protection claim 1.

advantageous Further developments of the inventions are the subject of the dependent claims.

Essential it is that while pressing on the movable furniture part at least one sensor sends an electrical signal to a control unit, d. H. a signal processor and a controller that sends Control unit converts this signal and a locking mechanism releases. This will be the bead breaker unlocked, regardless of the electrical device is, and thus the opening of the furniture part at least over a section allows.

advantage In this case, there is no optically disturbing grip anymore It must also be a risk of injury to the user In addition, the front gap itself can be almost zero and thus contamination of the interior of the furniture part can be prevented can. Another advantage over The prior art is that a very simple and inexpensive embodiment with regard to manufacture, assembly, maintenance, repair and operation, whereby the life of the opening of the invention and locking system, especially for Furniture parts, across from the state of the art is substantially increased.

Instead of a complex, electrically controlled electric motor as a drive unit for the jar of the ejector, z. B. according to the DE 20 2004 007 168 U1 and the JP 2003003746 According to the invention, it is now provided that the ejector can be unlocked via a simple electromagnet and can be driven via a passive mechanical energy store which stores passive energy stores in potential energy during the closing process of the furniture front (door or drawer, etc.) by the user. which in turn is then available for opening the furniture front. The retrieval of this potential energy of the energy storage takes place here via a lockable and lockable locking mechanism, the unlocking now according to the invention is carried out electrically by an electromagnet, for example via a solenoid, similar to a Wagner hammer a bell device.

Opening the furniture front takes place according to the invention by in particular pressure (but also by train) on the furniture front, whereby a sensor (touch sensor or more contactless Sensor) is actuated , which sends a signal to an electronic control unit is, and from this a control signal to the electrical locking mechanism, in particular in the form of a solenoid, is passed, so that the Locking mechanism is unlocked and thus the energy storage unhindered to act on the ejection element can and thus this in the opening direction in the direction of the furniture front can shift, eliminating the furniture front even from the furniture body is lifted and opens with it.

The closing process does not take place analogously in reverse, as in the prior art, so that hereby an energy saving, as well as a protection of the electrical locking mechanism, whereby this has a much longer service life. If now the furniture front is closed and pushed in the direction of the furniture body, it comes into contact with the ejector element, which is now pushed back under load of the energy storage back to initial position, so that the energy storage by conversion of kinetic energy in potential energy returns to its original state and with it charges. Now is the ejector and the energy storage element in its starting position, in turn, the Verriegelungsme activated and kept the ejector element in its original starting position in the retracted state (closed state). This re-locking can be done on the one hand via the electromagnet of the locking mechanism, possibly via the sensor activated, or purely mechanical, z. B. on the pushing back of spring-loaded detent balls through the cone of a rosette, so that then lock the locking balls behind the bevel rosette in turn in a groove and fixed there. An unlocking can in turn be done only via the electrical locking mechanism.

in the The following will now be referred to the type and execution, as well Positioning of the sensor, the control unit, the locking mechanism and the pullover itself, which can vary within wide ranges and thus in this regard the present one Invention not limited shall be.

When Sensor, a single sensor can be used, but preferably also two sensors per furniture part or more sensors, for greater safety to offer for the operation the furniture front, on any area of the furniture front. But it is important always, that when the front of the furniture part is pressed, at least a sensor registers this to the opening process with certainty to enable.

The Position of the sensor or the sensors can also be in large areas vary, namely For example, the arrangement of the sensors between a fixed and a movable furniture part, for example, between the furniture body and the drawer or the door or indirectly or directly between the carcase rail and the drawer rail, especially in the front or rear Area of the furniture part. Furthermore, the position of the sensors within the guide, in particular between the carcass rail and the drawer rail, in the rear Area of the furniture part be provided. Furthermore, as the position of the sensors, the one Locality otherwise used as a front buffer, namely between the furniture front and the furniture body, in particular on the back side of the door leaf or the Drawer front. As a further position of the sensors can be provided be that on or within a sealing lip between the furniture body and the furniture front, arranged on the carcass or on the front. Furthermore, can the position of the sensors provided in a special layer of the furniture front be embedded, especially in the front itself. As another execution the position of the sensors can these are provided on the front surface be.

A another, not preferred variant of the position of the sensors, if the sensors are not in the furniture part, So in body or furniture front, are arranged, but in another part of the installation of the furniture, z. B. within another part of a fitted kitchen, so z. B. on a countertop.

When further arrangement of the position of the sensors can be provided then these, for example, centered or punctual or areally or in relation to the rail guides can be arranged on one side or both sides, or a combination the aforementioned Types of arrangements.

When Type of sensors is claimed in the context of the present invention, that this is designed as a pressure sensor, in particular as a piezoelectric element could be, but also as a proximity sensor with Capacitive, inductive, optical or acoustic (ultrasound) Mode of action, or as an infrared sensor, or as conventional Switch.

The The mode of action of the sensors can therefore be carried out both with the user's touch, but also contactless, so only an approximation registered to the switch without direct contact contact by the user can be and thus a trigger the expeller over the locking device takes place. So, for example, too an approach be registered by the sensor for example 1 cm and possibly a trigger the Ausstosserelements by unlocking the locking device respectively. This distance value may possibly be adjustable.

Also should it be provided that an acoustic release of the Sensor takes place, for example by voice or noise detection, z. B. by clapping in the hands the user or by voting, for example, a defined audio frequency or sound intensity, z. By a whistle or by calling a word, e.g. "To open".

Also a response of the sensor by an infrared remote control is intended be included in the context of the present invention. Furthermore is provided in the context of the present invention that a detection a false trip taken into account by the sensors is what, for example, when cleaning the furniture front with a cleaning cloth, what in particular by the arrangement of at least two sensors, the spatial separated from each other takes place. Also a pollution on the furniture front can be taken into account be avoided, so that here too an undesirable false triggering avoided becomes.

As properties of the sensor and / or the Processing of the signals of the sensor by the signal processing, various parameters can be factory set or adjustable by the fitter and / or end customer. So z. For example, the triggering path for the sensor can be adjustable in particular, for example between values of about 0.1 to 1 mm, but also an adjustment of the triggering force, for example between 0.1 and 10 N, typically 5 N, or else a setting via the time, for example, a time window of about 1 to 5 seconds.

He follows a push or pull on the furniture front the user within these default parameter windows, so the sensor gives an electrical signal to the signal processing and control unit, which then the locking unit triggers.

Of course you can also the parameter window only in the signal processing and control device be defined so that the sensor when pressure or train on the furniture front always emits a signal and only in the signal processing and control device then the decision is made, whether intentional or unwanted activity is present.

The Signal processing and control unit can be within a block be present or even two separate blocks from each other. These units receive the electrical signal from the sensor either by electric cable or by radio signal, so that in the latter Case then the costly wiring can be omitted.

The Energy supply to the sensor is via batteries or rechargeable Accumulators, but especially with a low energy voltage of 12 or 24 volts, which previously had a transformer of Mains voltage 220/230 volts were brought to 24/12 volts.

It can per furniture part a single control unit may be provided, but it is also according to the invention in particular provided that in a whole furniture row, for example one Fitted kitchen, only a single signal processing and control unit is provided, so that then also the individual drawers and doors synchronized with each other can be and thereby a collision with each other can be avoided or else an overload of the furniture part, For example, when drawers are loaded with heavy content and pulling out several or all drawers are avoided should.

The Arrangement of the signal processing and control unit in the furniture part or within the furniture row or the entire kitchen should be freely selectable so they are also centrally located near a mains supply can be.

The Control signal from the signal processing and control unit is issued to the locking mechanism to unlock or cause locking, in particular via electrical Cable, however, in another embodiment of the present Invention over wireless radio (Bluetooth) or via a Infrared signal delivery (IR).

The fundamental Operation of the signal processing and control unit is that this the locking mechanism for the drawer or door or the ejector releases when the sensor sends a signal with a defined period of time, ie the front is pressed for a certain time by the user, so z. B. between 0.1 to 5 seconds. This avoids that the drawer or the door of the furniture part unintentionally opened is, so z. For example, if someone inadvertently hits the furniture part pushes or but a cleaning of the furniture surface takes place. This time window (sensitivity, time delay) could be set by the consumer may be predetermined in a simple embodiment, however be through the manufacturer. The beginning of the time window corresponds a tripping delay and the length the time window is then adjustable by the installer or the end user.

In a further embodiment is also the locking over Such a time window controllable, which in particular during the closing process the drawer is beneficial.

The Signal processing and control unit can simultaneously as a lock be used for others Furniture parts, if an already opened Furniture available is and as long as this remains open, then other furniture parts locked for opening stay.

With regard to the design of the locking mechanism, in turn, several possibilities are provided in the context of the present invention. So z. For example, the locking element may be in the form of a rosette known as a purchased part, with a conical head, followed by a ring-like collar of smaller diameter, followed in turn by a cylindrical collar of larger diameter. This rosette is inserted into a counterpart, whereby a locking takes place via spring-loaded balls, which then engage in the annular collar of smaller diameter detent and thus there is a firm, but releasable connection between rosette and counterpart. The spring-loaded balls can be pulled radially over an electromagnet from the engagement region of the annular collar of smaller diameter of the rosette, so that it is unlocked.

When However, locking mechanism can also be used e.g. provided a snap hook be, instead of the rosette known per se. This locking hook can be spring loaded be controlled by an electromagnet.

The Arrangement of the locking mechanism is preferably in the rear Area of the drawer, such. B., the first locking element on Be arranged body or the carcass rail, the second locking element, e.g. the rosette, but on the drawer or the decor or the drawer rail, mounted centrally or on one side. The first locking element corresponds here to the counterpart to the second locking element, wherein the first and second locking element together give the locking mechanism.

Of the Locking mechanism may also be e.g. in automatic feed the drawer slide integrated become.

At least a locking mechanism is preferred per piece of furniture used, however, can also two or more possible which are then released synchronized, so unlocked. Also, the lock could then done synchronized.

The The function of this locking mechanism is in particular electromechanical for the Unlock or release and in particular purely mechanically for locking, but can in another embodiment also for the locking and unlocking done electromechanically.

Especially the locking of the drawer or the movable furniture part takes place with the furniture body or with the fixed furniture part, if the locking mechanism is locked and no current flows, so that a mechanical lock is present. Should the locking mechanism be unlocked, so a brief flow of current must take place.

at the unlocking is in particular the second locking element, e.g. the rosette, from the first locking element (e.g., counterpart to the rosette) forced out and thus the furniture part something open, but by a much smaller amount than below the pullover himself accomplished.

Of the bead breaker consists of i.a. an energy storage and is a purely mechanical Part, so has no electrical elements such as a motor or an electric coil.

The Strength the spring can be adapted to the furniture part be, e.g. For light or heavy drawers or so the furniture part only a partial way or completely open can be.

When Energy storage is for example a spring, in particular coil spring, used, could however, in another embodiment the present invention also be an elastomer (rubber) or but over a gaseous Medium (eg air) take place. Even the energy storage itself could be one Lock include, as well as in particular the drawer / Door or but a part of the Abdrückers or ejector.

The in particular designed as a compression spring spring is in a housing for Stabilization between housing bottom and piston rod, wherein the piston rod temporarily in contact with a stop.

It can also be a spring-damper system act, allowing the release of the potential energy of the energy store then steamed, d. H. regulated, and thus the furniture front is not abrupt open but harmoniously at a slower speed. The Spring and damper are in particular mounted parallel to each other and this spring-damper system could also be designed adjustable. The spring-damper system can be used both for the opening movement also for the closing movement be provided or only for one of these movements.

The Arrangement of the bead breaker (Ejector, energy storage) is preferably between movable and fixed furniture parts, so z. B. in the lead integrated, preferably in a multifunction part at the front, free end of the drawer rail, where alternatively or additionally a Damper used can be or a touch-latch element or a automatic retraction.

The Number of push-offs is arbitrary, but at least one bead breaker per furniture part should be provided, possibly. also two per drawer and in particular one per side or drawer slide.

Of the bead breaker can in another embodiment of the present invention also integrated in the aforementioned locking mechanism so that then the locking mechanism and the ejector a Form assembly, whereby less space is required.

In principle, the arrangement of the electrical elements is chosen so that the wiring is minimal so that it is not disturbing to the end user and thus the cables because of the opening and closing the furniture part does not run the risk of being damaged. Possibly. the wiring can be omitted and instead a radio link between the individual electrical components, such. B. between sensor and signal processing / control unit and / or between signal processing and / or control unit and locking device done.

Instead of of cables could also a metal foil or a guide rail on the rear wall of the furniture part or the drawer be provided. In a continuing education can also the conductivity the metallic drawer slide, So the drawer rails and possibly used roles between the rails be so that an electrical wiring is then unnecessary.

in the The following is the invention by way of example with reference to the appended Figures and the illustrated there several embodiments explained in more detail, from which other advantages and features, and applications can be removed are.

1 shows a perspective view of a first embodiment of the opening and closing system according to the invention in the form of a drawer 1 which are inside a furniture carcass 2 is included and to this in the extension direction 31 is extendable and in this furniture body 2 in the insertion direction 32 is retractable.

The drawer 1 itself consists of two side drawer walls 3 that with a drawer bottom 4 connected with a front bezel 5 is connected, and a rear drawer rear wall 6 ,

The body 2 The furniture part consists of two side body side walls 7 , as well as an associated carcass back wall 8th , wherein the covering top plate and the covering bottom plate of the body are not shown here.

2 now shows a top view 1 with the closed drawer 1 . 3 shows the top view 1 with the opened drawer 1 ,

Between the drawer back wall 6 and the carcass back wall 8th is now the opening and closing system according to the invention 9 to 12 and 18 arranged, with the exception of the bead breaker 13 itself, in the front of the drawer between the drawer side wall 3 and the carcass side wall 7 is located, according to the 2 and 3 ,

The opening and closing device according to the invention therefore includes a control unit 9 , which has a power cord to the mains 10 connected, as well as another electrical cable 11 with the locking mechanism 12 , as well as over the electrical cables 19 with the sensors 18 that focus on attacks 24 located on the carcass side walls 7 are fixed. Between the back of the drawer 1 namely, the drawer rear wall 7 and / or the rear end of the drawer side wall 3 , and the sensors 18 is in the closed state of the drawer 1 a sensor gap 37 present, which is used to trigger the sensors 18 at least partially must be bridged, by allowing a user to the front 5 the drawer 1 suppressed.

The presser 13 is arranged in this example on the drawer rail (not shown) and lies down on the furniture body 2 , For example, here on the carcass rail (not shown), over the stop 17 at.

The presser 13 consists of a pestle 16 which is in a housing 15 is received and spring loaded over the spring 14 on the stop 17 on the carcass rail (not shown) applies.

In 2 is the front gap 33 to see a very small gap between the front 5 and the body 2 which distance may be substantially less than in the prior art, preferably less than 2 mm.

Will now by the user on the front panel 5 pressed and thus the front gap 33 bridged, so approach the two drawer side walls 3 the two sensors 18 on the attacks 24 , which causes the sensor gap 37 reduces and thereby the sensors 18 an electrical signal over the cables 19 on the control unit 9 give, in turn, over the cables 11 an electrical command signal for unlocking to an electric drive unit ( 22a ) in / on the locking mechanism 12 forward, then the second locking element, here the rosette 21 , from the first locking element 22 releases so that subsequently the energy of the energy store 14 (Spring) on the plunger 16 is given, which itself from the corpus firm stop 17 pulls off and the drawer 1 then in the extension direction 31 from the body 2 is ejected until the state of 3 is reached. The drawer can then be further pulled by hand from the furniture body, if the extension length should not be enough.

In summary, in the 1 - 3 the pullover 13 in the drawer 1 arranged (preferably in the drawer rail), the stop 17 on the body 2 (preferably in the carcass rail). The sensors 18 are in the back of the body 2 installed (on each one angle 24), which in contact with the rear wall 6 the drawer 1 when pressing on the front 5 reach. The control unit 6 is in the corpus 2 fixed, and connected via a transformer (230V to 24V) to the mains. The first locking element 22 with el. drive unit 22a is also on the body 2 fixed, the second locking element, here the rosette 21 , is on the back wall 6 the drawer 1 assembled. The advantage is that no cabling on the movable furniture part (drawer 1 ) must be provided.

The 4 and 5 show the top view of an alternative embodiment of the 1 to 3 , with a mechanical reversal of the mounting of the control unit 9 and the locking mechanism 12 so that the second locking element, here the rosette 21 , now on the back of the carcass 8th located and the cooperating first locking element 22 with el. drive unit 22a on the back of the drawer back 6 located, as well as the control unit 9 , Furthermore, in the 4 and 5 shown on both sides on both sides of the drawer 1 between the drawer side wall 3 and the carcass side wall 7 ever a squeeze 13 is located so that a smaller sizing of the spring 14 is possible, or a greater ejection force in the ejection direction 31 can be achieved with it.

Advantage of the first embodiment according to the 1 to 3 is that the control unit 9 with the power grid 10 can remain connected and thus no decoupling occurs to this, as in the second embodiment of 4 and 5 must be done. In the 4 and 5 is therefore a separation of the control unit 9 required from the mains, as in 5 with the drawer extended 1 can be seen. Is according to 5 the drawer 1 in the insertion direction 32 again in the furniture body 2 retracted, it is again a connection between the control unit 9 and power grid 10 by electrical means, in turn, the situation after 4 is achieved and a renewed extension of the drawer 1 is possible. The electrical connection between the control unit 9 and the power grid 10 Therefore, via a detachable electrical connector (not shown).

In summary, in the 4 and 5 two push-offs 13 in the drawer 1 arranged, preferably in the drawer rail, not shown, one per side, and the stops 17 are on the body 2 , preferably in the body rail, not shown. The sensors 18 are at the back of the back wall 6 the drawer 1 or drawer rail (not shown) installed, and are in contact with each angle 24 on the body 2 or with the carcass rail (not shown). The control unit 9 is on the back wall 6 the drawer 1 fixed, and connected via a transformer (230V to 24V) to the mains. The first locking element 22 with el. drive unit 22a is on the back wall 6 the drawer 1 , in the decor (not shown) or in the drawer rail (not shown) fixed, the second locking element, here the rosette 21 , is on the body 2 or mounted in the carcass rail (not shown) (or could even be integrated in the carcass rail: a tongue as a rosette is punched in the carcass rail). Advantage: conductive elements (rail, steel rear wall) can serve as cables. Disadvantage: when the drawer is opened, the connection control unit / mains should be disconnected, otherwise a long cable is necessary.

6 now shows a further alternative embodiment of the present invention, wherein the locking mechanism 12 now in the space between one of the drawer side walls 3 and one of the cabinet side walls 7 is arranged and the control unit 9 on the underside of the drawer bottom 4 located.

Furthermore, it is shown that the bead breaker 13 with associated stop 17 in comparison to the 1 to 5 a mechanical reversal was experienced so that the stop 17 is now attached to the drawer side and the presser 13 attached to the body side.

Furthermore, it can be seen that the control unit 9 a battery 23 possesses, over which the power supply of the control unit 9 and the further electrical components connected thereto electric drive unit 22a the locking mechanism 12 as well as sensors 18 he follows.
