Description

State of the art

In furniture devices for influencing the movement of movably received on a furniture body furniture parts are known in different configurations. There are considered devices which do not operate driven by electric motor, but which charging and kinetic energy from the outside by the action of a person on the furniture, for example by pressing or pulling on a piece of furniture can be fed.

As movable furniture parts come flaps, doors, drawers, pull-outs, trays or other furniture parts movably received on a furniture body into consideration.

Depending on the type of movement of the furniture part this is added to the furniture body on different fittings or bearing and guide assemblies. The furniture part may be translationally and / or rotationally movably guided on the furniture body, in particular, rail guides in the form of partial or full extensions or fittings such as hinges are used.

In the case of corresponding furniture, a furniture part can be activated in a closed state relative to the furniture body by a corresponding release action, so that with a furniture part opening device, the movable furniture part can be moved out of the closed state into an opening direction of the furniture part at least over a part of a maximum possible opening distance.

For example, so-called touch-latch devices are known, wherein a non-moving in the closed state furniture part is pressed from the outside by a user, so that the furniture part undergoes a small displacement movement in the closing direction while the furniture part opening device is activated and then after pushing a driven Moving out or ejecting the movable furniture part from the depressed position in the opening direction of the furniture part takes place.

In addition to the advantage of an intuitive operation is advantageously no separate or visually appearing in appearance control or grip element for gripping the furniture body closed furniture part is necessary with a touch-latch device, which is particularly advantageous for aesthetic reasons.

Furniture part opening devices are also exposed to operating conditions, the z. B. may occur due to improper handling. Therefore, it is required to design the furniture part opening devices accordingly, in order to avoid an unwanted or loud impact of the furniture part on the furniture body, for example, in a strong throwing the movable furniture part from an open position in the closing direction. Also accidental or unintentional triggering to activate the furniture part opening device is observed. An unintentional triggering of the furniture part opening device can lead to damage to facilities or possibly injury to persons.

Purpose and advantages of the invention

Object of the present invention is to provide a device for an opening movement of a furniture part in particular of the type mentioned above or a furniture part opening device, which is improved in terms of a desired operating characteristics and undesirable operating conditions.

In particular, an unintentional triggering of an opening mechanism should be prevented.

This object is solved by the independent claims. In the dependent claims advantageous developments of the invention are set forth.

The invention relates to a device for an opening movement of a movably received on a furniture body furniture part from a closed state in an opening direction, wherein the device comprises a force accumulator and acted upon by the power storage movably mounted opening element, which is securable in a standby position via a securing element of a securing mechanism , wherein prior to the opening of the opening movement, the opening element is Entsicherbar from the standby position in which the opening element undergoes a release movement against the opening direction while the securing element is released, wherein in the normal operation of the assembled device, the release movement by a corresponding pressure force from the outside to the furniture part by a User is feasible. It is in particular mechanical opening devices for furniture parts whose driving force for moving the furniture part is not electromotive or is not supported motor. The opening element can be displaced and / or swiveled acted upon by the force accumulator and thereby open the furniture part.

The essence of the invention lies in the fact that, in addition to the securing mechanism, actuatable release means acting on the securing mechanism are present on the opening element, which can be brought into a release position, as long as the release means are actuated from the outside, wherein the release position is a prerequisite to unlock the opening element by a movement against the opening direction.

As long as the release means are actuated from the outside, means in particular that the release means are placed in an operating state.

The release means are particularly advantageously designed as a separate release member. Under the assembled device, the device in the furniture body and / or the furniture part functionally correct condition to understand.

With the releasing means acting on the locking mechanism on the opening element, the operating safety and reliability of the opening device can be improved. In particular, an unintentional triggering of the opening element from the secured ready position can be avoided or it is achieved that only a deliberately desired release operation actually leads to a release or release of the furniture part opening device. In this connection, the unlocking is necessary so that a triggering operation of the opening device causes ejection of the furniture part from the closed state in the opening direction. Unlocking and releasing via the release means can be done separately or superimposed. The Entsicherungsmechanismus and the release mechanism are preferably coordinated such that they lead in cooperation to the desired opening function, but constructively work separately or be separately actuated or controlled separately. This advantageously also subsequent retrofitting of known security mechanisms is possible, which may preferably remain unchanged, so that an inventive arrangement based on it can be provided. In particular, advantageously only the release means must be set up, but adapted to the existing security mechanism.

The release agents intelligently set up an additional requirement for those states in which false tripping due to inadvertent release has previously been possible or has occurred on a regular basis. Advantageously, the desired in normal operation unlocking and release remains as previously completely undisturbed and in particular is not complicated, but corresponds to a previous operation. The operator thus makes no particular difference when operating the furniture provided with the invention, compared to a known arrangement with a corresponding securing mechanism. Preferably, an existing touch-latch device and the intended action on it remains unimpaired by the invention.

Previously, it was disadvantageous that a triggering of the securing mechanism was not only possible in the intended situation by a pressure actuation example of the furniture part in the closed state, but the locking mechanism readily in other states, especially in terms of the position of the furniture part, was Entsicherbar.

This can result in unintentional triggering of the opening element in corresponding operating situations, for example when the furniture part is open, because the furniture part is already open or a movement in the closing direction is desired, which then means a collision with the outgoing opening element.

Such scenarios are realistically not possible according to the invention. In particular, it is advantageously arranged with the invention that not only the securing mechanism must be unlocked, which makes a movement in the closing direction of the securely held opening element necessary, but also the release means must be actuated in the release position to fully unlock the opening element from the standby position to be able to.

Advantageously, both adjusting operations, ie regarding the securing mechanism and the release means, are automatically reset when not in operation or canceled before reaching a necessary minimum adjustment path, so that advantageously at least phase-wise simultaneousness or superimposition of the two operations is necessary.

An accidental bumping on the secured opening element, whereby this is moved slightly in the closing direction, does not result in opening of the furniture unit to open the opening element, since the release means are tuned so that a simultaneous actuation of the release means by the accidental bumping usually does not take place.

Also a sole z. B. accidental actuation of the release means in secured opening element is not a problem, since the locking element holding the opening element in its standby position thereof is uncoupled or unaffected and the opening element remains secured.

For a sole presence of an operation of the release means in a release state, which is a prerequisite for unlocking the Securing mechanism for the opening element is just as little for activating or triggering the opening or ejection operation, as it is not sufficient to act solely on the securing mechanism, with the aim to unlock it.

The arrangement according to the invention is also advantageous for mounting the opening device according to the invention on the furniture. For in the assembly, it is in practice so that the opening device is mounted in the state of the secured and retracted opening element and this should remain so until the furniture is completely assembled and then carried out a functional check of the opening device. This is advantageous, because initially the opening device is generally more compact in the securing state of the opening element, because the secured opening element is retracted or folded to a base body of the opening device and therefore does not protrude or protrude from the opening device, which complicates the assembly or would disturb. The device can be easily attached to the furniture in the compact state z. B. screwed or infected.

Also, under the force of the force accumulator biased opening element in an accidental release during assembly by the sudden moving out of the opening element to injury to the fitter and / or damage to the furniture part, which is inventively also avoided.

The release means and the securing mechanism are coordinated, in particular spatially and constructively, that it is almost impossible for a user of the furniture or, for example, a fitter, to unintentionally release the secured securing mechanism during assembly and at the same time adjust the release means accordingly to a release position , In particular, both the securing mechanism and the release agent must be in a corresponding action situation over a minimum period of time. On the one hand, the securing mechanism must experience a continuous inward movement in the closing direction, based on the furniture part, which thus allows no interruption or slackening in the action on the opening element, and on the other hand, the release means must be permanently actuated accordingly over this phase, otherwise the release means without actuation in a Blockadestellung are that does not allow release of the locking mechanism. In this case, the release means are advantageously also designed so that the release means have to bridge by pressing a Mindestverstellweg to allow a release of the securing mechanism, which also makes it difficult to accidentally trigger the secure opening element. A slight contact between the release means or a corresponding part of the release means is not sufficient to actuate the release means, since a preferably adjustable predeterminable minimum force is necessary for this purpose. The specification of the minimum force, for example, by an exchangeable existing energy storage of the release agent such. B. a preloaded spring, which can be selected differently depending on the desired level of force.

The release means, for example, a corresponding component such as a release member are z. B. advantageously spring-loaded or kraftbeaufschlagt mounted on the opening element displaceable. In a non-actuated ground state, the release means are in a position which does not allow the locking mechanism to be released.

The same applies to the inward movement of the secured opening element, wherein the force to be applied correspondingly must act against the force of the force accumulator of the opening element in order to move the opening element in the closing direction. An additional power storage alone for this function is not necessary because the power storage for moving out of the unlocked opening element and the ejection of the furniture part takes on this task.

Is the opening element in its secure standby position, so is only a very specific or defined action on the Freiagabemittel and at the same time on the securing mechanism according to a regular operation suitable to bring the secure opening element from its secure position and thus an opening movement of the furniture part by the opening element to start.

An advantageous development of the invention is characterized in that the release means are configured such that when the device is mounted, the release means in the closed state of the furniture part acted upon by the furniture part and adjusted in the release position, whereby the opening element by a release movement by acting on the furniture part in the closed state is securable. Thus, the control operation is taken into account, according to which advantageously the release means are adjusted in closed position on the furniture body furniture part by the furniture part itself in the release position.

Because in this state, an expected operating situation is such that a user wants to open the closed furniture part or activate the opening device, which in particular requires a touch-latch device pressing the furniture part in the closing direction, with which the locking mechanism should be solved. The release agents should in this situation, over the most of the time during the use of the furniture prevails, so just not be in the blocking position and are therefore advantageously adjusted from the closed furniture part or automatically in the release position.

Further, it is advantageous that the release means are adapted to assume a blocking position in a contactless state of the furniture part, in which the secured via the securing mechanism opening element is not unlocked in a movement against the opening direction. With this arrangement, a situation in the installed state or in the use state of the opening device is simulated, in which the furniture part is not closed, that is already partially or completely open and thus there is no need or even undesirable, the opening element from the secure state to solve. Advantageously, a release is prevented or blocked via the release means correspondingly in the blocking position. So far, no additional measure is known for such cases, which regularly leads to false triggering, for example, an unintentional abutment on the opening element, which is freely accessible through the unobserved existing in front of the opening element furniture part, this unlocks, so that the opening element in the connection movement in the opening direction performs. The opening element then runs into the void or executes an action without function.

It is also advantageous that the release means in the blocking position form a mechanical stop for a movable securing part of the securing mechanism. This makes the release agents easy, reliable or less susceptible to interference and robust. In general, the securing mechanism in addition to a movably mounted securing part on a cooperating with the securing part counter portion, such as a guideway. The securing part is in particular designed to be pivotable and / or displaceable, for example, a securing pawl, which is defined in interaction with or along the opposite portion, for example, a heart curve adjustable. The securing part is advantageously spring-loaded on the opening device, for example on a base body, on which also the opening element is mounted. If the securing part and the counterpart section come together when the opening element moved out of the ready position is reset, there is a positively guided interaction between the securing part and the counterpart section. The opening element then passes first into a catch position or in the sequence shortly thereafter in the secured standby position on the opening device, in which the opening element remains stationary and only after a de-energized release in particular by a touch-latch functionality under impressions of the furniture part is moved out again and the furniture part is ejected in sequence.

An advantageous modification of the subject invention is characterized in that a contact portion on the opening element is present, which is in a common movement of the furniture part and the opening member in contact with the furniture part, Under the common movement is the contact-type joint movement to understand. This means that the contact portion over the entire duration of the common movement of the opening element and the furniture part in contact with the furniture part. Conversely, it is such that as soon as the contact between the contact portion and the furniture part is canceled, no other not permanently connected to the furniture part portion of the opening element with the furniture part in contact. The release means are temporarily or in phases in contact with the furniture part, as long as the contact portion touches the furniture part. In general, in a common caused by the unlocked opening element opening movement of the opening element and the furniture part, the release means out of contact with the furniture part before the contact portion and thus the opening element separates from the furniture part.

For transmitting an opening force of the contact portion, for example, with an inner side of a front part of the furniture part in contact.

The contact section on the opening element is designed, for example, as a roller mounted around a fixed bearing point.

The contact section is different, in particular, from the release means or a release member, or it is a matter of different and spaced-apart elements or sections.

In a further advantageous variant of the invention, the contact portion and the release means are coordinated such that in the closed state of the furniture part when the furniture part at the contact portion of the furniture part also bears against the release means and adjusts the release means in the release position. In the closed state of the furniture part when pressing the furniture part in the closing direction, therefore, the contact portion in contact with the furniture part and in addition, the release means are brought into contact with the furniture part in the release position.

Thus, the release means, in the closed state of the furniture part before the moment of Acting on the furniture part in the closing direction, without a blocking effect on the securing mechanism. The unlocking of the locking mechanism can take place without delay or immediately with the impressions of the furniture part.

Advantageously, the device is designed in such a coordinated manner that in the assembled state of the device after Eindrückvorgang the furniture part undergoes an opening force in the opening direction in contact with the contact portion of the opening member under the effect of the movable out of the force storage element opening element. The force effect of the force accumulator in the opening direction on the opening element and thus on the furniture part can only be effective when the opposite action force from the outside by the user, so the impressions of the closed furniture part, for example, in the millimeter range, no longer takes place. A user is intuitively anyway, as he is accustomed to this in particular with furniture with a touch-latch device, only briefly press from the outside against the furniture part and immediately afterwards drain from the furniture part, so that the ejection force can be effective through the opening device.

It is also advantageous that the contact portion and the release means are provided at a free end portion of the opening member in the longitudinal direction of the opening member offset from each other. This is particularly advantageous for structural reasons or with regard to a desired effective power transmission from the opening element to the furniture part.

It is further proposed that according to an advantageous embodiment of the subject invention, the opening element is verschenkbar, in particular is designed as a pivotable ejection lever. In the case of a drawer, door or flap, the pivoting axis is in particular vertical or horizontal. Thus, advantageously, the opening device may be attached to the furniture, for example, on a vertical side or rear wall or on a horizontal floor or cover element of the furniture body.

A swept by the opening element in operation swept between the pivoted ready position and a position in which the opening element loses contact with the open furniture part, for example, between about 30 and 50 degrees and more. After sweeping over an ejection angle, the ejection lever is returned to the standby position.

Furthermore, it is advantageous that charging means for charging the energy accumulator are formed by further movement of the furniture part in the opening direction after the opening movement via the opening element. This is advantageous because a user of the furniture usually after a discharge operation via the opening element, the furniture part manually reopened, in order to load or unload the furniture part thereafter. The charging or tensioning of the energy storage thus takes place immediately after the discharge without delay, wherein the force is to be applied for charging by the person.

It is particularly advantageous when the loading means are configured, by moving the furniture part further in the opening direction after the opening movement via the opening element, to transfer the opening element back to the standby position. In particular, it is advantageous if the loading means are designed in such a way that superimposed with the loading of the energy store, the moved out opening element pivots back into the ready position. For this purpose, the force accumulator and the opening element can be correspondingly forcibly linked with each other, wherein a moving out of the opening element from the standby position is coupled with an at least partial unloading of the energy storage or vice versa a reintroduction into the standby position loading of the force accumulator conditionally.

In principle, the charging process of the force accumulator and the retraction of the opening element can also take place separately or decoupled from each other, for example successively.

In particular, can be realized with the loading means, a transmission mechanism by which after removal of the contact between the furniture part and the opening element as the opening operation of the furniture part advances a displaceable portion of the loading means on the opening element transmits a force which pushes the opening element back to the standby position. For this purpose or for the transmission of motion, the loading means may comprise a joint mechanism with two levers. A first lever of the hinge mechanism can be articulated at each end of the furniture part and on a mitbewegbaren intermediate joint. A second lever may in turn be articulated at each end on the intermediate joint and on the opening device, so that with the movement of the furniture part of the opening device associated end of the second lever comes into contact with the opening element that the opening element is pressed into the standby position. The second lever preferably acts on one end of an opening element designed as an ejection lever, which is opposite to the end in the region of which the contact section is present.

The ejection lever is designed in particular as at least two-armed lever whose a lever arm length between the pivot axis and the contact portion is several times greater than a lever arm length between the pivot axis and the portion at which the second lever of the hinge mechanism of the loading means comes into contact when loading the energy accumulator or during pivoting back of the ejection lever.

With the arrangement described a coupling takes place such that adjusts a movement reversal of the opening element after the ejection process, whereas the furniture part is moved unchanged in the same direction namely in the opening direction.

Finally, it is also advantageous that a damper arrangement is provided for the damped opening movement of the opening element out of the ready position. For this purpose, conventional Dämpfanordnungen are conceivable, in particular with a piston-cylinder unit.

With the damper arrangement, the opening movement of the opening element and thus of the furniture part can advantageously be carried out in particular evenly. The damper arrangement equalizes the sudden acting force of the charged energy storage. Thus, the opening movement of the opening element is damped and thus the ejection movement of the furniture part from the closed state.

In particular, it can thus be avoided that a so-called rebound effect occurs, ie the furniture part rebounds by an undamped ejection effect of the opening element during the opening process after a release of the contact between the opening element and the furniture part of this initially against the opening direction or in the closing direction, which is undesirable.

The invention also relates to a piece of furniture with a furniture part movably received on a furniture body, which in the closed state can be triggered by a pressure force from the outside relative to the furniture body. For example, the furniture may be a furniture body with a movably received thereon drawer or a pivotally mounted door or flap.

Advantageously, a device according to one of the above embodiments is present on the furniture.

In a pivotable furniture part, the furniture part z. B. be received by a hinge pivotally, in which a damping is integrated, which is attenuated at a closing movement of the furniture part this at least on a last Schließwegabschnitt before reaching the closed state or gently braked.

In a slidably received on a pull-out or over a partial or full extension relative to the furniture body furniture part, a damped sliding movement of the furniture part when closing before reaching the fully inserted closed state by z. B. an automatic feed with damper be realized.

Further features and advantages of the invention are explained in more detail with reference to a schematically illustrated embodiment.

Show 1 to 5 a device according to the invention mounted on a piece of furniture shown in detail in different operating positions or times, starting with 1 and ending with 5 set one after another with ascending figure number. To illustrate the assembled device, individual parts of the furniture body are not shown in the figures.

The 1 to 5 show a furniture part opening device according to the invention 4 standing at a furniture body 2 is mounted, the device 4 this serves as a furniture flap 1 trained furniture part relative to the furniture body 2 in the opening direction according to movement arrow P1 (s. 3 ) from one according to 1 shown closed position relative to the furniture body 2 to move or eject. The furniture part opening device 4 has a touch-latch functionality, which is explained in more detail below.

The furniture body 2 includes two side walls 2 B and 2c and an intermediate vertically aligned body wall 2a , The furniture flap 1 is about a hinge arrangement 3 , which is designed here as a damped cup hinge, pivotable about an axis perpendicular to the plane of the drawing. The pivoting movement is from according to 1 shown basic position according to arrow P1 in the opening direction or away from the furniture body 2 and in the opposite direction or in the closing direction relative to the furniture body 2 pivoted out. The hinge arrangement 3 attacks on an inside 1a the furniture flap 1 via a recessed hinge pot, which is connected to another hinge body, which on the side wall 2 B firmly fixed, for example, is screwed.

The hinge arrangement 3 does not belong to the furniture part opening device according to the invention 4 , but is necessary for movably receiving the furniture part on the furniture body.

According to 1 is the dormant furniture part opening device 4 for ejecting the closed furniture flap 1 in their basic position. The furniture part opening device 4 includes the components described below. A base plate 5 , on which all other components of the furniture part opening device 4 are recorded is fixed in position at a predetermined mounting position on the body wall 2a fixed, wherein the furniture part opening device 4 except for individual sections inside in the furniture body 2 offset to a front end face is positioned. In the closed state ( 1 ) of the furniture flap 1 is its inside 1a opposite and aligned parallel to the front of the furniture body 2 ,

Also, an elongated, multi-arm ejection arm 6 trained opening element about a rotation axis S pivotally mounted on the base plate 5 added. From the ejection arm 6 is in the 1 to 5 only a lower half-shell or a lower part shown, with a lower part of the Auswerfarms shown 6 matching top in the assembled state the Auswerfarm 6 completes and the interior of the ejection arm 6 covers.

The ejection arm 6 is from a mechanical energy store 7 applied, which exemplifies a biased compressed coil spring 8th in a sleeve open at the end 9 having, wherein the sleeve 9 articulated about a plane perpendicular to the plane axis S1 is movable. At the sleeve 9 opposite end of the coil spring 8th is a pen-like endcap 10 fixed in pressing contact with a force introduction point on Auswerfarm 6 stands. The ejection arm 6 has two different force introduction points, which it by an adjustment of the end cap 10 in one of the two load transfer points, which on the Auswerfarm 6 from the energy store 7 to realize acting force differently. For the latching recording of the front rounded end cap 10 are two corresponding arcuate bulges 11 and 12 in the lower half shell of the ejection arm 6 educated. According to 1 to 5 is the end cap 10 in the free end of the ejection arm 6 closer bulge 11 engaged, bringing one to the catch in the other bulge 12 comparatively stronger force on the Auswerfarm 6 is realized. This allows the furniture part opening device 4 adapt advantageously to different ejection tasks, in particular depending on the expected in practice weight of the ejected furniture part, which possibly depends on housed in the furniture part objects or a loading condition. The displacement of the end cap 10 of the energy store 7 from a bulge in the other bulge is readily possible without tools, for example, by hand with a handle.

At the free end of the ejection arm 6 is a rotatable role 13 trained contact section present, the role 13 at a positionally fixed bearing point of Auswerfarms 6 is present and for contacting the Auswerfarms 6 with the inside 1a the furniture flap 1 serves or on the inside 1a can roll in an ejection process. To minimize noise when ejecting the role 13 for example, be rubberized on the outside.

In the basic position according to 1 rest the furniture flap 1 in its closed state and stands with the inside 1a on the roll 13 at. This forms a closing gap 14 with the size a in the millimeter range between the inside 1a and a front or front narrow side 2d the side wall 2c out. For adjusting the size of the closing gap 14 with a turning tool is an adjustment with an eccentric screw 28 available.

In the basic position according to 1 is the furniture flap 1 in particular aligned parallel to front sections of the furniture body 2 ,

So in the closed state of the furniture flap 1 the ejection arm 6 under the effect of the tensioned energy store 7 can not swing out or the furniture flap 1 does not move in the opening direction P1 is at the furniture part opening device 4 a security mechanism 15 educated. The security mechanism 15 includes various sections or components both on the Auswerfarm 6 itself as well as on the base plate 5 , In the security mechanism 15 The touch-latch functionality is integrated, with one called the heart-shaped curve 16 trained guideway on Auswerfarm 6 is designed. The heart curve 16 has in the illustrated lower part of Auswerfarms 6 up against a flat main side of the lower part upstanding edges, which curve sections 16a and 16b form, with which a counter section or a guide nose 18 one as a tentacle 17 trained securing element of the securing mechanism 15 cooperates along feasible.

The tentacle 17 has at its front free end, the guide nose 18 on which by force provided forcibly at the heart curve 16 along feasible or in a catch situation according to 1 is held to it. So the guide nose 18 can perform a corresponding movement is the tentacle 17 about an axis perpendicular to the plane of the drawing S2 something in the counterclockwise direction and deflected. About the axis S2 is the tentacle 17 at the base plate 5 added. Also, on the tentacle 17 on both sides transversely projecting collar 17a and 17b designed, which with a tensioned tension spring 19 interact, being in a parallel to the tension spring 19 standing alignment of the collar 17a and 17b no adjustment force on the tentacle standing in a neutral position 17 acts or in deflected positions (s. 1 . 4 . 5 ) a restoring force in the direction of the neutral position on the tentacle 17 is exercised. A neutral position of the tentacle 17 show the 2 and 3 , wherein the movement arrow P3 in 2 indicates that the tentacle 17 from the in 1 shown deflected position by the tension spring 19 has reached the neutral position.

The tension spring 19 is shown by way of example as a tensioned spiral spring, which under train via two fastening tabs on a recess of the base plate 5 clamped in place.

The heart curve 16 includes the island-shaped curve section 16a and a tooth-shaped curved portion slightly spaced therefrom 16b , wherein a free distance between the curve section 16a and a tip of the curve section 16b is slightly larger than an outer dimension of the guide nose 18 , so that these at a corresponding relative movement of the heart curve 16 and the tentacle 17 or the guide nose 18 between the curve sections 16a and 16b passes, what with a corresponding deflection of the tentacle 17 connected in a counterclockwise direction.

In accordance with 1 shown basic position is the Auswerfarm 6 resting in a over the securing mechanism 15 secured standby position, so is due to the charged energy storage 7 and the on the base plate 5 pivoted and locked secured position ready to swing out after a release or release and the furniture flap 1 eject.

After the release is under the effect of the energy storage 7 the ejection arm 6 counterclockwise folded out about the pivot axis S and presses it in contact with the roller 13 the furniture flap 1 away in the opening direction.

In the secured state of the ejection arm 6 are a trough-like depression 16c the heart curve 16 in the curve section 16a and the guide nose 18 pressed against each other, resulting in the action of the energy storage 7 takes place, bringing the Auswerfarm 6 from the tentacle 17 is held securely and firmly. For unlocking the curve section must 16a from the guide nose 18 moved inward, which is the size a of the closing gap 14 by pushing in the furniture flap 1 in the direction of the arrow P2 (s. 2 ) is possible. This maximum inward moving state of the furniture flap 1 or the Auswerfarms 6 shows 2 ,

With the impressions of the furniture flap 1 directs the guide nose 18 according to P3, because the tension spring 19 the tentacle 17 offset counterclockwise, and comes out of the trough-like depression 16c free. The ejection arm 6 is no longer on the base plate 5 locked. From the position according to 2 follows an ejection movement of Auswerfarms 6 through the preloaded and extending spiral spring 8th with a movement of the furniture flap 1 in the opening direction P1 up to a maximum swinging position of Auswerfarms 6 according to 3 ,

Swinging the ejection arm further 6 from the position according to 3 in the opening direction is by loading means 20 the furniture part opening device 4 prevented. A further swing is not necessary because the partially open furniture flap 1 can now be easily grasped by a user by hand and opened further.

The loading means 20 serve to charge the at least partially discharged energy storage 7 after the ejection process according to 3 and swing back the Auswerfarms 6 , The loading means 20 include a cocking lever 22 and a connecting rod 21 making a permanent hinged connection of the furniture part opening device 4 with a hinged section of the furniture flap 1 forms. The connecting rod designed with a slightly crease-shaped course 21 is in each case on the one hand to a pivot axis S3 perpendicular to the plane of the drawing on one of the furniture flap 1 attached front mounting part and articulated about a further vertical axis S4. About the axis S4 is the connecting rod 21 with the clamping lever 22 connected. The tension lever 22 itself is in turn at the base plate 5 pivotable about a further axis vertical S5 and includes in addition to a connecting portion 22a to the connecting rod 21 a Einwirkabschnitt 22b , at the moment of the maximum pivotability of the ejection arm 6 according to 3 on the ejection arm 6 acts, so coupled with the further movement of the furniture flap 1 in the opening direction P1 of the Auswerfarm 6 is pivoted inwardly into the ready position, which in opening the furniture part between the states occurring in accordance with 3 and 4 happens.

4 shows an operating situation in which the Auswerfarm 6 over the loading means 20 has already returned to its fully backward ready position. This is done by counterpressing a straight flank 22c of the exposure section 22b on as a role 27 illustrated ball bearing, which with the pivoting of the Einwirkabschnitts 22b the ejection arm 6 with the opening of the furniture flap 1 is pivoted back in a clockwise direction. Once the role 27 the contact with the flank 22c loses (s. 4 ) is from the Einwirkabschnitt 22b no further movement effect on the Auswerfarm 6 transferred, although the role 27 now on one to the flank 22c subsequent curved guide section 22d slipping, what 5 suggests.

Just before the ready position of the swiveling Auswerfarms 6 reaches a ramp 29 of the curve section 16a the guide nose 18 the undeflected tentacle 17 that's along the ramp 29 forcibly guided and deflected clockwise until the guide nose 18 after the end of the ramp 29 under the action of the tension spring 19 again slightly counterclockwise in the trough-like depression 16c is offset and locked there in the standby position or secured, with a securing force according to the force of the coil spring 8th ,

In addition, the furniture part opening device comprises 4 a damper assembly 23 , which is exemplified as a piston-cylinder unit and a cylinder 23a and one relative to the cylinder 23a internal and movable pistons (not shown) with one out of the cylinder 23a outstanding piston rod 23b includes. The damper assembly 23 serves for damped opening movement of the Auswerfarms 6 from according to 1 out standby position shown. With the swinging back of the Auswerfarms 6 is on the damper assembly 23 put into an initial situation, the cylinder 23a in one to the piston rod 23b moved out position is moved (s. 1 ). Moving the cylinder 23a is through one on the cylinder 23a acting on the cylinder 23a hinged connecting arm 24 at the ejection arm 6 coupled with the movement of the ejection arm 6 realized. The damping takes place by the cylinder 23a according to arrow P5 ( 3 ) is moved to the piston decelerating, so no so-called rebount effect occurs or the furniture flap 1 at the end of the ejection process does not strike back in the closing direction.

Furthermore, in the standby position according to 1 the inside 1a the furniture flap 1 in fitting contact with release means, which in the embodiment according to the invention designed as a release member hinged to Auswerfarm 6 stored safety lever 25 include. The two-armed safety lever 25 is displaceable about an axis perpendicular to the plane of the drawing S6 and a coil spring 26 biased. A first end 25a of the safety lever 25 protrudes in a vertical direction to a front edge 6a the ejection arm 6 in the direction of the furniture flap 1 slightly wider, for example, by a millimeter over, than the roll 13 to the front edge 6a protrudes viewed in the vertical direction. The role 13 and the end 25a come offset depending on the pivoting position of the Auswerfarms 6 in contact with the inside 1a the furniture flap 1 , for example 3 clarified. With closed furniture flap 1 according to 1 is the safety lever 25 from its blocking position (s. 3 to 5 ) offset by the furniture flap 1 in contact with the end 25a of the safety lever 25 this counterclockwise against the force of the coil spring 26 pushes away and the safety lever 25 slightly deflects, so the safety lever 25 in the in 1 shown deflection position or release position is offset.

The safety lever 25 also has a socket 25b on, which is attached to a paragraph 30 the ejection arm 6 supports, and a hook-shaped bent and to the heart curve 16 directed finish 25c that is for interaction with the guide nose 18 the tentacle 17 is trained.

Below is an operation of the furniture or the furniture flap 1 explained by a user in regular operation.

Starting from the ready position according to 1 will the furniture flap 1 by pressing on an outside 1b pressed inwards according to arrow P2 and the in 2 shown triggering or Entsicherungsposition the Auswerfarms 6 reached. The release of the tentacle 17 from the secured position is only possible because of the safety lever 25 through the pressing inside 1a the furniture flap 1 is pressed and thus the end 25c the way for the guide nose 18 releases and so the Auswerfarm 6 can be unlocked when pressing in. Without operating the safety lever 25 (S. 3 to 5 ) is the end 25c Aligned so that there is a mechanical stop for the guide nose 18 and the tentacle can not escape from the secured position when the Auswerfarm 6 is pressed.

On the other hand, with the impressions of the Auswerfarms 6 according to 2 , as already explained, this unlocks what by the existing there release position of the safety lever 25 is possible. After unlocking and swinging out the furniture flap 1 comes the inside 1a out of contact with the end 25a of the safety lever 25 so that this under the action of the coil spring 26 comes in its backup or stop position and also when swinging back the Auswerfarms 6 remains in this.

5 shows the fully opened furniture flap 1 relative to the furniture body 2 , wherein also the articulation of the connecting rod 21 on the front attachment part on the inside 1a the furniture flap 1 is apparent.

When closing the opened furniture flap 1 this is done by one in the hinge assembly 3 accommodated damper assembly damped swung back to the starting position according to 1 reached and the inside 1a on the roll 13 and at the same time in the end 25a the safety lever 25 is applied and this again put into its release position.

Will the furniture flap 1 from the in 1 shown closed state pulled without pushing outwards in the opening direction, advantageously remains the Auswerfarm 6 secured, so do not swing, because the Auswerfarm 6 does not experience any push-in movement and also at the moment of lifting the inside 1a the furniture flap 1 from the safety lever 25 this gets into the securing position.

Will the furniture flap 1 after an ejection process and after the loading or clamping operation of the energy storage 7 by a user over a partial closing distance in the closing direction and then moved back into the opening device, prevents the safety lever 25 that the tentacle 17 his middle position according to 2 reached and thus the Auswerfarm 6 not released or released. This is relevant because here the Einwirkabschnitt 22b about the role 27 a slight inward movement on the secured ejection arm 6 causes what then without safety lever 25 would lead to an unwanted moving out of Auswerfarms.

With the arrangement according to the invention is also prevents that during assembly of the furniture part opening device 4 unintentional swinging out of Auswerfarms 6 takes place or this is released, since a swinging out would only take place if accidentally simultaneously the safety lever 25 operated and the Auswerfarm 6 would be pressed in, which is extremely unlikely.
