The device comprises a dischargeable energy storage mechanism (19) and charging means for charging the energy storage mechanism (19). Using the device mounted on the furniture item, the furniture item part can be moved by an ejection process, during which a discharge of the energy storage mechanisms (19) takes place, in an opening direction. According to the invention the charging means are designed in such a manner that in the mounted state of the device on the furniture item, after reaching a position of the movable furniture item part in which said part is open with respect to the furniture item, the discharged energy storage mechanism (19) is charged by a further movement of the movable furniture item part out of the open position that has been reached, irrespective of the direction of the further movement of the furniture item part.

Description

"Furniture, device for the motion control of a

Furniture part and device for locking an element "

The present invention relates to a device according to claim 1 and claim 12 and a furniture according to claim 13.

State of the art

Devices for influencing an opening movement of furniture parts and their direct or indirect locking are known, for example devices with so-called touch-latch arrangements, wherein the furniture part on

Guide units, for example, partial or full extension with mutually telescopically sliding slide rails, is guided on a furniture body displaced. For one

comfortable handling of the furniture part this can be moved with the help of a power storage from a closed position relative to a furniture body position in the opening direction without a user must act during this phase of the opening movement. The movable furniture part can usually over a stretch of a maximum possible or

zurücklegbaren distance between a closed position and a fully open on the furniture body open position by the influencing device pushed open or

be ejected. Then after that of the

Furniture device caused reaching a partial

opened position of the furniture part, the furniture part through

CONFIRMATION COPY the user manually moved comfortably.

For a next ejection process, the force accumulator which at least partially discharges during ejection must be recharged or brought back into a sufficiently charged state. For this purpose, the user must apply a force to load the energy storage. In the charged state of

Force storage, it is also necessary, a spontaneous

Move out of the furniture to avoid or the

Secure energy storage against unintentional unloading. The movable furniture part can thus, when it is again in the closed position, be ejected again at the next ejection operation. As a rule, this is done before a simple triggering action to start the ejection process by the user. The triggering action can be advantageous by the user acting on the furniture or the movable furniture part

take place, for which purpose, for example, a touch-latch arrangement can be used.

Purpose and advantages of the invention

The object of the invention is to provide furniture or devices of the aforementioned type with regard to improved ease of use.

This object is solved by the independent claims.

The dependent claims relate to advantageous variants of the invention.

The invention is initially based on a device or a furniture device for influencing the movement of a furniture part accommodated on a furniture part, wherein the furniture part via guide means for a guided movement in a

Opening direction and in one of the opening direction

opposite closing direction is movable, the

Device comprises a dischargeable power storage and charging means for charging the energy accumulator and wherein with the the furniture-mounted device, the furniture part by a discharge operation in which a discharge of the power storage takes place, is movable in an opening direction.

Under a force storage device is in particular no memory for electrical energy such as a battery or a part of an electric machine or a motor understood, but in particular a purely mechanical energy storage, in particular a force storage, which is formed by spring means. With the energy storage is so to speak a driving force for the ejection process or a

Ejection movement of the movable furniture part of a

Closed position provided relative to a furniture body of the furniture. The ejection movement takes place in particular via a first part of a possible opening path of the

Furniture part from a closed position to a maximum open position. After an ejection operation, the movable furniture part can be moved further by manual action or pushed back again - or further pulled out.

A first essential aspect of the invention is that the loading means are designed such that in the mounted state of the device on the furniture after reaching an open position relative to the furniture of the movable

Furniture part, a charging of the discharged power storage by moving the movable furniture part from the reached open position regardless of the direction of the

Moving further of the furniture part takes place. This is the

Reaching the open position caused by a discharge operation. For an advantageous operation of the furniture part is possible. In particular, the movable furniture part can be operated intuitively by a user, whereby always a charging of the discharged energy storage takes place.

So far it is only about a fixed movement of the

movable furniture part possible, a charging of a discharged energy storage by moving the movable

To get furniture part. With other movements, the

Force memory can not be loaded, which is disadvantageous. According to the invention, regardless of the direction of movement of the movable furniture part is always a charging of the

Power storage, what by an intuitive operation of the

Furniture part done. Since the unloaded state usually follows then moving on, found with the

Move on after the ejection always a charging of the energy storage instead.

The further movement of the movable furniture part can be done in both possible directions of movement of the furniture part. It is usually the case that the movement without changing the selected direction of movement or without a reversal of movement of the furniture part until reaching the state of charge of the

Force memory must take place to load the power storage in an uninterrupted process or effectively.

The arrangement according to the invention is also advantageous in terms of assembly. Because the assembly always takes place

the same, regardless of how the user would like to charge the energy store. So far, generic furniture device in different configurations and / or dependent on a desired charging option

be mounted differently, which is disadvantageous

especially if at the time of initial assembly the fitter is missing the appropriate information. So it happens regularly, that at a later time after the initial installation, a conversion of the furniture device must be made.

Preferably, a pivotable about a pivot axis

Ejection lever provided, wherein a pivoting movement of the ejection lever under the action of the discharging

Force accumulator causes the movement of the furniture part in the opening direction, wherein the ejection lever has an ejection section

which can be brought into abutment with the movable furniture part for an ejection process and a displaceably mounted second lever of the ejection lever is provided, the

Ejecting operation, at least after a cancellation of the system of the ejection section on the movable furniture part with a with the furniture part (1) mitbewegten guideway is in contact and is displaceable with the ejection operation in an engaged position on the ejection lever. The second lever is in particular during the ejection contact of the ejection section on

Furniture part and thus due to the kinetic energy of

Furniture part offset in the engaged position. Of the

Power storage must be designed so that the

Motor energy of the furniture part is sufficiently high or to a desired degree. The contact of the second lever with the furniture part is usually not right at the beginning of the ejection process, but only offset to an onset of the ejection process contact of the ejection section with the furniture part. The second lever remains from or after the abolition of the system of the ejection section on the movable furniture part in contact with the guideway. The contact of the ejection section with the furniture part is in the course of

Ejecting the furniture part forcibly lifted, as the

Pivoting axis of the ejection lever is fixed and the ejection lever forms a limited effective ejection lever to the pivot axis. The second lever is in contrast with a

variable lever arm to the pivot axis formed or

stored accordingly displaceable. The second lever remains after lifting the contact of the ejection section on the furniture part at least as long in contact with the guideway until the energy storage after its unloading again completely

is charged, which is usually correlated with the locked retracted position of the ejection lever.

Due to the interaction of the second lever and the guideway, the further movement of the furniture part after the ejection process is coupled with the further movement of the ejection lever and in particular a loading phase of the force accumulator with the

Swing back the ejector lever.

In addition, the ejection process can be accomplished to a lesser degree or in a final phase by the second lever. Although the ejection process is determined essentially by the interaction of the ejection section with the furniture part in the main ejection phase or the dominant part of an ejection effect on the movable furniture part by the Ejection section z. B. comes to rest on a part of the movable furniture part and pushes the movable furniture part under the action of the energy storage in the opening direction or ejects.

A pivoting lever arrangement is particularly space-saving and reliable use for a motion transmission by means of a mechanical power storage. The energy storage device preferably remains permanently via an effective lever

Swivel axis engaged on the ejection lever. The ejection lever is swung out by the charged energy storage in a first pivoting direction for ejecting the furniture part, wherein upon pivoting back of the ejection lever in a second of the first pivot direction opposite direction

Recharging the discharged energy storage takes place.

According to the invention it is ensured that after the

Ejection process, the interaction of the furniture part in its direction independent movement continues to swing back the ejection lever. When pivoting back the ejection lever is advantageously no contact of the ejection section with the furniture part instead, but only a contact with the second lever. Because the ejection section attacks advantageously on a front side of the furniture part, which is transverse to a

Movement direction of the furniture part extends, that has no depth in the direction of movement, whereby a coupling between the ejection section and furniture part in the direction of movement of the

Furniture part constructive is not possible. In contrast, the second lever can come into contact with the guideway, which along the direction of movement of the furniture part or

especially its depth extends.

Advantageously, the guideway has different spatially oriented sections, in particular with regard to a gradient or inclination. In this case, the guideway runs at a furniture part erected in accordance with its intended purpose in its longitudinal extent parallel to a horizontal. The direction of movement of the furniture part is parallel to this horizontal.

Points of the guideway point in the longitudinal direction of Guideway considered different distances to an axis parallel to the direction of movement of the furniture part.

Advantageously, the guide track on the movable furniture part is present, for example, formed with this uniform or integrated into it and / or subsequently or separately attached thereto. Advantageously, with the movement of the furniture part, the guide track can be moved and depending on the second lever or the ejection lever acted. Basically, so is the coupling of

Movement of the furniture part with the stationary swiveling

Ejector made.

But it is also possible that the guideway to the

Guiding means is formed, in which case different sections of the guide means come into question. Becomes

For example, a rail guide as a guide

used, for example, a full extension with carcass, center and pull-out rail, the guideway may be present on one of the three mentioned rails. For example, at the

Carcass rail or fixed position relative to the furniture body or on one of the moving rails of the guide means, wherein the movement of the pull-out rail with the movable

Furniture part coincides. When attaching the guideway to the center rail, the guideway moves z. B.

slower than the pull-out rail or the movable furniture part.

If the guideway attached to the movable furniture part, different attachment points come into question. The

Guideway, for example, be arranged on the underside of the movable furniture part, for example, at the bottom of a drawer bottom of a drawer.

Also, a lateral or rear attachment to the furniture part is conceivable. For example, on one side or a rear wall of the movable furniture part opposite to a side or rear inside of the furniture body.

This can advantageously, depending on where a sufficient space is available, the guideway or the ejection arrangement are positioned.

Next, it is advantageous that a loadable

Secondary energy storage is present, which acts on the second lever. This can also be the second lever by its force-transmitting interaction with the guideway

supportive of the ejection process. In particular, in a predeterminable phase of the ejection movement of the furniture part on the SekundärkraftSpeicher a force to eject the furniture part act. This force acts advantageous even when the primary or stronger energy storage no longer expels, because the ejection section is no longer in contact with the furniture part.

For example, it is advantageous that the second lever on the pressure spring, for example a coil spring, the second lever

Preloaded lever is added. Thus, the second lever can be pressed under the action of the secondary energy storage in a second phase or final phase of the ejection process against the guideway, resulting in a force component in the ejection direction of the furniture part. Advantageously, the discharged secondary energy storage is charged in the preceding first phase of the discharge operation by the

Ejection lever ejects the furniture part while the second lever is urged by conditioning on the correspondingly shaped guideway against the force of the secondary energy storage in a recessed position on the ejection lever or clamped it.

Preferably, the second lever and the ejection section are provided on a common lever arm of the ejection lever, wherein the ejection lever is formed as at least two-armed lever. The ejection lever may have a first lever arm, which is acted upon by the force accumulator, so that, in particular, a tensile force provided by the force accumulator acts on the first lever arm. At the other or second lever arm of the two-armed lever, the ejection portion and the second lever are present. The part of the ejection section which contacts the furniture part in the first phase is preferably at a free end of the second lever arm or formed with a maximum lever length to the pivot axis, wherein the guide track

contacting part of the second lever between the

Swivel axis and the free end of the second lever is present.

Preferably, the ejection lever is pivotable about a pivot axis and back, which is positionally fixed relative to the furniture. This concerns the case of the ejector lever arranged relative to the furniture body or the guide track present on the furniture part. But it is also one with the furniture part

mitbewegter ejection lever and thus the pivot axis

possible if the guideway z. B. positional on

Furniture body is formed.

It is further proposed that in the assembled state of the device, the second lever and the guide track are matched to one another such that in abutment with each other the ejection process of the furniture part can be supported. Preferably, the system of the second lever on the guideway at

Ejecting operation set when the ejection portion is no longer applied to the movable furniture part, so that the

Ejecting action with the second lever beyond the first phase is extendable. Thus, with the second lever, a contact time between the ejection lever and the movable

Furniture part be extended in time, otherwise

comparable conditions.

This is advantageous because the second lever like a

Prolonging the ejection effect of a simple ejection lever acts, such as a lever arm extension of the lever arm formed with the ejection section, but what happens

Space reasons or constructive in general is not possible. With the second lever can advantageously be realized without extension of the effective ejection lever on the second lever an extended ejection effect.

It is also advantageous that in the mounted state of the device, the second lever and the guideway in such a way are matched to each other that in contact with each further moving the movable furniture part of the

Eject position reached pivoting the ejection lever causes. With the movement of the second lever along the guide track, the ejection lever is forcibly swung back, and thus also the first lever arm, so that with the pivoting back the loading of the force accumulator takes place.

In the assembled state of the device, it is advantageous for the ejection lever and the energy accumulator to be superposed on one another

coordinated that a swinging back of the

Ejector causes charging of the energy storage.

Is the pivot axis of the ejection lever set in an imaginary center of a clock and held one end of the energy storage in extension of a "13 o'clock position" fixed position and with the other end on the first lever arm of the ejection lever in the region of a "12 o'clock position" under Train is mounted so that the first lever arm after the ejection operation, which takes place under pivoting of the ejection lever in a clockwise direction, for example, in a "13 o'clock position", is pivoted backwards pivoting the ejection lever in the "12 o'clock position. Position "back, the coil spring again pulled apart or extended according to the previous shortening during the ejection process and thus the on

Ejector acting tensile force, which correlates with the stored force, again increased or reset to the initial value. In this position, the ejection lever can then be secured or releasably locked, in particular with a device for locking the ejection lever z. B a so-called touch-latch arrangement.

Advantageously, the guideway is formed on an attachable to the movable furniture part mounting member.

In particular, the guideway on a so-called

Spannkeil be present, the clamping wedge on the

movable furniture part optionally subsequently in one of several possible different attachment positions

can be fixed or removed again. The assembly component can be formed, for example, as a flat component with flat main sides and narrow sides, wherein a

Section of the narrow sides forms the guideway. Another section of the narrow pages may also have others

Take on management tasks to guide the furniture part movement. A flat part is easy to produce, low in weight and space-saving and easy attachable.

Preferably, the clamping wedge is separately attachable to a bottom, for example, a bottom of a drawer. there

Correlate different sections of the guideway with different pivoting positions of the ejection lever in the mounted state of the clamping wedge or the ejection device, by the contact of the second lever to the respective

Section of the guideway. This applies due to the design both for the pivoting position when swinging and the pivoting back of the ejection lever.

In an advantageous modification of the subject invention, the guide track has a changing course for the installation of the second lever, with an intermediate section and adjoining the intermediate section on both sides

Main sections. It depends on a position of the furniture part on the furniture, which changes with the guided movement of the furniture part, for example, depending on one

Displacement or pivoting position of the furniture part relative to the furniture body, the second lever at different points of the guideway in plant. Preferably, the second lever is apart from a first comparatively short

Movement phase when opening the furniture part from the

Closed position or the ejection movement and a final phase of the closing movement, in which an automatic retraction can act, in contact with the guideway.

It can be different between different contexts

Interaction of the second lever with the guideway

be differentiated. When the ejection lever with the

Ejection section ejects the furniture part and the second lever is not locked on the ejection lever, but by the Secondary power accumulator is in a moved out position, the second lever is pressed in abutment against a first major portion of the guideway by a corresponding, for example, to the ejection lever convexly curved shape in a retracted position, against the force of

Secondary energy accumulator. In subsequent subsequent particularly straight-line or receding course of the first

Main section is moved out under the action of the intermediate preloaded secondary energy storage of the second lever of the contour of the guideway following the ejection lever and pressed against the guideway that a correspondingly directed and sufficiently large force acts on the furniture part, so that the furniture part a movement component in

Opening direction experiences and the ejection movement of the

is supported movable furniture part. From the moment in which the ejection section in the last phase of

Ejecting process comes to rest on the furniture part, the pivoting position of the ejection lever remains substantially

unchanged. When the second lever reaches the intermediate portion of the guide track at the end of the discharge operation, the discharge operation is completed. The

Guideway is formed in the intermediate portion so that due to the abutment of the second lever in the intermediate portion of the further movement of the furniture part counteracts a relatively high resistance, which is achieved by a, for example, sink-like shape of the intermediate portion. The lower section in the intermediate section or recessed guide track has, for example, edge-side flanks or an inlet and outlet side at the intermediate section, over which the second lever can only be moved past, if on the

Furniture part a constructive predetermined minimum force in

Opening or closing direction of the furniture part is applied. This can be done by an external influence on the

Furniture part done by the user, after the

automatically expiring ejection process, the furniture part manually opens or closes again.

In the subsequent interaction of the second lever with the same main section, when the furniture part is closed again is, or with the other main portion of the guideway when the furniture part is opened further, the second

Lever, controlled by the shape of the inlet and outlet side at the intermediate portion, moved to a locking position on the ejection lever, so that this then as a rigid part of the

Ejection lever acts and a fixed lever arm is set to the pivot axis of the ejection lever. Only later

Canceling the contact between the second lever and the

Guideway, the locking position is lifted at the ejection lever again.

When moving the furniture part in the appropriate

Direction when locked at the ejection lever second lever, presses the guideway or its rising and / or in particular rectilinear edge against the detected second lever. In this case, the ejection lever against the action of

Ejector lever memory swung back. The force required to do so will be affected by the user's intervention

Applied furniture part, wherein the contact force substantially corresponds to the force for charging the force accumulator, since the proportion is in addition to be overcome in addition frictional forces negligible.

The guideway is further designed so that after a predetermined distance in the considered movement of

Furniture part by the action of the user, for example, about a third or half of the total possible Öffnungsbzw. Closing distance of the furniture part can make out, the

Ejection lever is brought into its fully zurückschwwenkte position, at the end of this movement, the energy storage again in its original or initial

Charge state is located. The furniture part is usually completely open or completely closed. The

Swinging back of the ejection lever as described above is in particular by a in the direction in question

considered reduction of the distance of the guideway of the main sections to the ejector lever assembly or to an imaginary parallel to the direction of movement line reached by the pivot axis of the ejection lever. For the interaction between the guideway and the second lever or a contact portion of the second lever, it is advantageous if the contact portion in the

concerned phases, so apart from the initial phase of the ejection process and the final phase of the closing operation, without interruption or continuously guided on the guideway is present, for example in a sliding and / or rolling contact. The contact portion of the second lever may comprise, for example, a rotatable roller, roller or a wheel.

As explained above, it is advantageous that the guideway is tuned such that by the plant of the second

Levers at an intermediate portion of the guideway of the

Ejection lever occupies a relation to a starting position preferably pivoted maximum position. With or shortly before reaching the fully swung-out position

loses the ejection process until then for the

Ejecting process authoritative ejection section the contact with the furniture part.

In principle, it is preferred if the guideway is formed without a step or jump or an edge-like transition, but a continuous path

represents. The guideway serves as a track on which the abutment portion of the second lever runs. The guideway is in particular just designed and has sections with in particular different spatial inclinations, wherein curved and / or rectilinear sections of the guideway may be present.

In particular, the main sections are of an outer one

Area of the guideway seen to the intermediate portion sloping or formed with opposite inclination.

Basically it is possible that end at the

Guideway to the total length of the guideway

comparatively short end portion of the guideway of z. B. 5 to 10% of the total length is present at which then the Connect main sections, the at least one

End section can be customized and

For example, a facilitated inlet or outlet of the second lever when contacting or leaving the

Guideway allows. The two main sections may in particular have a substantial length of the guideway

For example, each about 40% to 50% of the entire guideway.

It is further proposed that the guideway is tuned such that during the movement of the furniture part a

Takes place along moving a main portion of the guide track on the second lever, wherein the ejection lever in the direction of ^'the pivoted starting position is zurückschwenkbar. This is as explained above advantageous in terms of a controlled action on the ejection lever when further opening or further closing the furniture part after the ejection process.

Preferably, each of the two main sections for one of the two possible directions of movement of the furniture part in

Connection to the ejection process formed. A first

Main section is in a further movement in the opening direction and a second main section for advancing in

Closing direction of the furniture part in charge or effective by its investment in the second lever. The two main sections are basically similar in terms of swinging back the ejector lever. The effective during further opening first main portion connects to the intermediate portion in the direction of a rear side of the furniture part or in the closing direction of the furniture part, whereas the further moving in

Closing direction effective second main section in the direction of a front side of the furniture part or in the opening direction adjoins the intermediate section.

It is also advantageous that the mounting member is formed such that different mounting positions of the mounting member, in particular on the movable furniture part for a purposeful interaction with the ejection lever are possible, so that depending on the respective mounting position maximum possible ejection path of the movable furniture part with the ejection lever is predetermined. Will the mounting component

for example, mounted on the movable furniture part and

For example, offset closer to a front, can be achieved that the furniture part after the ejection operation relative to the furniture body by the interaction of the

Ejecting lever on the guideway is ejected less far than in a mounting of the mounting member closer to one of the front side opposite located back of the movable furniture part.

Thus, the ejection device can be particularly flexible or used for different customer needs. In particular, all variants of the charging of the energy accumulator are covered with the device according to the invention, regardless of whether that

Charging should be done with the opening or closing of the furniture part. Advantageously, moreover, without the need for different mounting components or with one and the same mounting component, the length of the ejection section can be selected differently.

A further advantageous embodiment of the invention is characterized in that the second lever on

Ejection lever is guided displaceably via a linear guide. The linear guide may be, for example, in the manner of a slotted guide or designed in a simple configuration as a slot guide. In the backdrop or the

Slot can be performed a portion of the second lever, for example, protrude a protruding engaging portion in a guideway, whereby a safe back and forth movement of the second lever along the linear guide is possible.

Further, it is advantageous that the second lever on

Ejection lever is received such that the second lever passes in a predetermined relative position on the ejection lever in a detent position on the ejection lever, in particular by a pivoting movement. Preferably, the moving is in the

Detent position in which the second lever is rigid on Exhaust lever is locked exists, only in the linear fully disengaged state of the second lever on

Ejection lever possible. This will ensure that otherwise the second lever for the ejection support, as explained above, will be under the effect of

Secondary force accumulator moves along the guideway and in this way the guideway following with his

Adjustment section or can come to this plant. The transition to the locked state is preferably possible only in a selected or predefinable position on the ejection lever. In particular, in a completely moved out on the ejection lever position, for example by a possible only in this position low pivotability relative to the ejection lever, so that while the locking position

is reachable. The necessary small pivoting can be done against the action of the secondary energy storage in the interaction of the second lever with the guideway

for example, by the by moving the

Furniture part with moving guideway brings the second lever in the locked position or presses.

It is further proposed that a latching arrangement is provided, by which the second lever on the ejection lever is releasably latched, in particular with which the second lever can be brought into the latching position on the ejection lever. The second lever may be in two different states on the ejection lever, a first state in which the second lever is movable relative to the remaining ejection lever, and a second state in which the second lever is locked or rigidly provided on the other part of the ejection lever ,

Furthermore, it is advantageous that the ejection lever is designed as a multi-arm lever with respect to the pivot axis, with a first lever arm, which attaches to the force accumulator and a second lever arm, on which the ejection section are present. It is particularly advantageous if a third lever arm is present, which comprises the second lever or is formed by this. This is structurally advantageous, since a high functionality can be achieved with the ejection lever, in particular at the ejection lever or with respect to the common

Pivot axis several separately operable with the respective lever arm acting systems can be realized with different mechanical characteristics. An effective system relates, for example, to the interaction of the force accumulator with the pivoting of the ejection lever, another the interaction of the ejection section with the furniture part and another the interaction of the second lever with the guideway.

In addition, a multi-arm lever assembly for reasons of space is advantageous, especially since these transverse to a

Swing direction is flat building.

The invention also relates to a device for

Locking a movable element in one

Locking position and release of the lock, wherein the release of the lock by a movement of the

movable element takes place against a force acting on the movable member and a movably mounted

Pivoting part is provided with an engagement portion such that the pivoting part is caught in the locking position at a counter portion.

In this case, the essential aspect of the invention resides in the fact that a spring element is provided, with a first end which acts on the pivoting part and with an end which is opposite the free end and which is fixedly mounted, wherein the

Spring element on the pivoting part at least over a

Part of the possibility of movement of the pivoting part exerts a bias.

In particular, a preferred embodiment of the invention relates to a so-called touch-latch arrangement, hereinafter also referred to in part as a furniture device, for a piece of furniture with a furniture part accommodated on it. The

Furniture device can be mounted on the furniture

In particular cooperate with a discharge assembly for ejecting the movable furniture part or integrated in this be. The ejection arrangement can be formed, for example, by the above-described device according to the invention for influencing the movement with the ejection lever and the force accumulator acting thereon. The ejection lever in this embodiment forms the movable element, which is held locked in its pivoted-back position, which takes place with the device according to the invention for locking.

To trigger the ejection movement, the locked movable element is released from the lock. Under the effect of the force acting on the movable element or the charged

Force memory, the now released movable element by its movement act on the furniture part, that the furniture part moved out of a closed position or

is ejected.

In principle, it is also possible that the movable element is the furniture part itself or a section present on this. After the release of the furniture part from its locking relative to the furniture body with the proposed device, the furniture part can be ejected through the ejection arrangement, for example by a against the furniture part

pressing ejector lever on which the force memory acts. In this embodiment, an indirect force on the movable element or the furniture part by the

Power accumulator realized on the ejection lever. For example, the ejection lever may press against a rear wall of a drawer and the lock of the drawer may be provided at another location or separately thereto. The ejection lever itself need not be locked.

In both cases, however, can only after the release of the

Locking the movable element, the ejection effect on the furniture part are active.

The movably mounted and preloaded recorded

In particular, pivoting part has an engaging portion, which cooperates with a curve along which the Engagement portion is guided and a relative movement between the pivoting part and the curve can be predetermined. The curve is present, for example, on the movable element. In the locking position of the movable element is the

Swiveling part on a latching contour section of the curve

trapped, wherein by a directed relative movement between the locking contour portion and the engaging portion in the direction opposite to the force acting on the movable element of a

Direction of moving out the locking position can be canceled, so that the engagement element is released and guided guided along the curve movable and the ejection element is ejected. After the release of the lock, the pivoting member is moved by the spring element in a rest or waiting position, from which comes when renewed moving the movable element with the curve thereon of the engaging portion in contact with the curve and interacts with this. With the

Moving the movable element is the

Engaging section then caught again under the action of the spring element on the curve at a curved section formed therefor and the movable member in the

Locking position held.

This is a particular space-saving and reliable acting device for locking a movable

Furniture part in a closed position and to release the

Lock specified.

The invention also relates to a piece of furniture with one of the aforementioned devices. This allows the advantages already discussed above to be carried on a piece of furniture, in particular on a furniture carcass with a displaceable one

realized drawers.

Figures 13 to 17 a manual pushing the drawer 1 following the ejection process.

On the furniture body 2 a drawer 1 is displaced

taken in accordance with Figure 1 and 2 unaffected by a user and relative to the furniture body 2 is closed. The inventive device is for the

Movement influencing the drawer 1 is formed and is also referred to below as a furniture device 3. FIG. 1 shows a perspective bottom view and FIGS. 2 to 17 show a plan view according to the arrangement from FIG. 1, wherein a view of the furniture device 3 is shown in FIG

Drawer bottom la is not shown.

The drawer 1 is designed as a full extension 4 Guide means on the furniture body 2 slidably added recorded. The guide means comprise two guide rails 5 and 6, each in a receiving space of

Hohlkammerzargen forming the sides of the drawer 1,

recorded are. The guide rails 5 and 6 each include a drawer rail associated with the drawer 1, a cabinet rail associated with the side walls 2a and 2b, respectively, and a middle rail intervening therebetween. With the guide means, the drawer 1 can be transversal or parallel to a

Longitudinal axis L (see Figure 1), which has a displacement axis of

Drawer 1 represents, or parallel to the side walls 2a, 2b are moved back and forth relative to the furniture body 2.

Basically, the guide rails 5 and 6 are suitable alternatively to serve as underfloor guidance or to be arranged under a drawer or on the underside of a drawer bottom, such as in a wooden drawer, which is displaceable over an underfloor guide on the body.

Transversely between the guide rails 5 and 6 or at their respective and opposite body rails a stationary mounted part of the furniture device 3 with a base plate 7 is present at this. At the flat or

space-saving accommodated and except for a recess 7a rectangular base plate 7 is as a discharge lever. 8

trained and charged with a power storage

Ejector pivotally mounted about a pivot axis S. The ejection lever 8 serves to eject the drawer 1 closed according to FIGS. 1 and 2 or from a pressed-in one

Position according to Figure 3. The ejection takes place in

Opening direction relative to the furniture body according to movement arrow P3 of the drawer 1 (see Figure 4).

Furthermore, the furniture device 3 comprises a separate or separate from the base plate 7 and with the

Drawer 1 mitbewegten part, which is designed here as a mounting component or concretely as clamping wedge 9. The also flat-built clamping wedge 9 is in the illustrated embodiment at the bottom of the drawer bottom la via two slots 10, 11 and fastened corresponding screw means, wherein a floating bearing of the clamping wedge 9 is realized transversely to the longitudinal direction L. With the floating storage becomes one

low clearance for the clamping wedge 9, for example, in the millimeter range allows for a displacement movement of the drawer 1 optionally an evasive movement of the

Spannkeils 9 in particular transversely to the longitudinal direction L to

allow so that the clamping wedge 9 and thus the drawer 1 when moving can not jam, which could otherwise happen due to assembly and / or component tolerances. When moving the drawer 1 come rotatable support rollers 32, 33 on the fixed part of the guide rail 5 for guiding and / or supporting purposes for the drawer 1 in a

functionally correct pressure roller contact on a frontal running surface 31 on the clamping wedge. 9

The drawer 1 comprises a front panel existing aperture 12, which defines a closing gap 13 in the closed state according to Figure 1 and 2 with its directed to the furniture body 2 inside, which is between the inside of the panel 12 and front end sides 14 and 15 of the side walls 2a and 2b formed. The free end of a first lever arm 20 of the ejection lever 8 is formed by a contact roller 21, wherein by their position or by the position of the

Locked or locked ejection lever 8 according to Figure 2, which presses against the inner panel 12, the gap of the closing gap 13 is determined.

The panel 12 opposite the drawer 1 also has a rear wall 16.

The drawer 1 is shown in Figures 1 and 2 by means of a

Also device according to the invention held in the closed position, which is designed as a touch-latch assembly 17. In this case, according to Figure 2, the ejection lever 8 is received in the recess 7a and thereby locked in a zurückgeschwenkten position, so that a front side 8a of the lever arm 20 within an imaginary rectangular border of the

Base plate 7 is positioned. The touch-latch arrangement 17 allows a release of the locking of the ejection lever 8, which is done by pressing the drawer 1 against the opening direction of the drawer 1 by a user or from the outside. For this purpose, the pressing on the inside of the aperture 12 ejection lever 8 by a Mindestschwenkweg or by a few

Angular degrees are pivoted counterclockwise to accomplish the actual release of the locking of the ejection lever 8.

The function of the touch-latch arrangement 17 will be discussed in detail later.

The depression of the drawer 1 in the closing direction according to the arrow PI for releasing or releasing the locked position takes place until abutment of the diaphragm 12 on the end faces 14, 15, which Figure 3 shows. The drawer 1 is then ejected by the released after pressing ejection lever 8 and its pivoting out, as explained in detail below.

The designed as a multi-arm lever ejection lever 8 is pivotable about the furniture body 2 fixedly positioned pivot axis S. A first lever arm 18, which in the basic state of the furniture device 3 according to Figures 1 and 2 in the longitudinal direction L, has at its free end an attachment point for a trained as a spiral spring 19 power storage. The spiral spring 19 forms a primary energy storage or

superordinate or dominant energy storage of

Furniture device 3. The coil spring 19 is relatively strong in the ground state shown in Figure 1 and 2 and thus loaded the energy storage. When triggering the ejection process by pressing the drawer 1 (Figure 3), the

Spiral spring 19 only slightly further excited.

With the effective tensile force generated by the coil spring 19 on the ejection lever 8, this is pivoted clockwise after its locking release (Figures 4 and 5) and ejected by conditioning the second lever arm 20 on the panel 12, the drawer 1 over a first section. The touch-latch assembly 17 and their triggering by

Pressing the drawer 1 in the closing direction according to arrow PI will be explained below. With the impressions and thus the small swinging back of the ejection lever 8 is formed as a tentacle 22 with spring tongue 22 a (Figure 12)

Engagement element or pivoting counterclockwise direction according to the arrow P2 deflected about a pivot axis S3 of the tentacle 22. With the deflection according to P2, which can be predetermined by means of a curve 34 on the lever arm 20, the locking of the ejection lever 8 is released or released. The curve 34 determines the movement of the evasive swivel-mounted

Fangarms 22 by the spring tongue 22 a guided along or guided according to the curve 34 along.

FIG. 4 shows the front section of the arrangement according to FIGS. 2 and 3 in an already slightly pushed-open state of the drawer 1 during the ejection process by swiveling the ejection lever 8 in direction P4 by contracting the prestressed spiral spring 19. The contact roller rotatably mounted about the axis S1 rolls 21 of the lever arm 20 over an area inside along the aperture 12. The drawer 1 thereby moves according to arrow P3 and in the opening direction of the

Drawer 1 out of the furniture body 2 out.

Figure 4 also shows the moment of the ejection process, in which a second lever 23 which is movably mounted on the second lever arm 20 under the action of a spring constructed as a secondary force accumulator 30, with its front free end by an existing there

Contact roller 24 comes into contact with a guideway 25. The guideway 25 is at an inwardly directed Schmalbzw. Front side of the clamping wedge 9 present. With the contact between the guideway 25 and the second lever 23 is a coupling between the drawer 1 and the clamping wedge 9 and the furniture body 2 fixed part of the furniture device 3 and the discharge lever 8 takes place. The furniture device 3 is tuned or is it

constructive conditions that almost simultaneously or only with one comparatively small time or movement offset the

Contact roller 21 with the inside of the aperture 12 out of contact, when the contact roller 24 comes to rest on the guideway 25.

In particular, after release of the ejection contact by the contact roller 21, a controlled coupling between the further movement of the drawer 1 and the pivoting position or movement of the ejection lever 8 is achieved. The second lever 23 is via a linear guide relative to the ejection lever. 8

preferably received on the second lever arm 20 movable. The linear guide comprises a slot 26 in the second lever arm 20, in which a secured therein or guided movable

Pin member 27 (not shown) on the second lever 23 engages. By the end portions of the elongated hole 26, the second lever 23 is limited in its linear displacement movement on the second lever arm 20 to a maximum linear

Displacement distance a (see FIG. 4).

The second lever 23 can not only be linear along the

Linear guide can be moved, but it can in a by the compression spring 30 at least almost in the maximum

Linear guide extended position according to z. B. Figure 3, 9 or 13, also slightly about a pivot axis S2 in

To be deflected clockwise. The pivot axis S2 is positioned concentrically with the longitudinal axis of the pin element 27.

If the second lever 23, for example, according to Figure 9 or 13 by conditioning a correspondingly shaped

Guideway portion 25f (Figure 9) and 25d (Figure 13) of the guideway 25 is slightly pivoted, which by the

Movement arrow P5 is indicated in Figure 9 and 13, engages a formed in the front portion of the second lever 23 latching nose 28 in a tuned or fitting

designed corresponding mating contour 29, for example, a latching notch, wherein the second lever 23 is then fixed in this position, if it continues to be pressed, that the second lever 23 can perform no linear movement along the slot 26. Once the second lever 23 is no longer is pressed or no longer in contact with the

Guideway 25 is located or at least not in one

Accordingly directed Andrückkontakt with the guideway 25 is, by the rear or rearward on the lever 23rd

pressing pressure spring 30 causes a directed moving out of the second lever 23 from the mating contour 29 and thus repealed its fixation. For this purpose, a laterally offset to the pivot axis S2 attack point of the compression spring 30 is realized on the lever 23, resulting in a moment on the lever 23, which leads without counteracting force to a deflection of the lever 23 counterclockwise out of the mating contour 29 out.

In the state z. B. according to Figure 4, the second lever 23 is deflected by the contact with the clamping wedge 9 counterclockwise so according to the arrow P4 in Figure 4 and away from the mating contour 29 and thus reliably prevents a catch. Thus, the lever 23 can be pressed in or linear through the

Compression spring 30 are pushed forward or against the displacement direction P6 (Figure 5), this being possible only to the extent that the guide rail 25 allows outward movement of the second lever 23 along the slot 26.

If, starting from FIG. 4, the ejection lever 8 is pivoted further forward according to P4 and the drawer 1 is ejected, a guide track section 25b curved inward or transversely to the longitudinal direction urges the second lever 23 in the direction of the arrow P5 along the slot 26 in that the second lever 23 on the second lever arm 20 is retracted counter to the pressure force by the compression spring 30 (FIG. 5). In this case, the furniture device 3 or the coil spring 19 and the compression spring 30 are coordinated so that the resulting forces acting on how

lead described cause of action.

With the moving out of the drawer 1, therefore, the second lever 23 is inserted on the lever arm 20, which in this phase of the ejection lever 8 is not counterclockwise

is pivoted back. The coil spring 19 is designed stronger in its force effect compared to the force of the compression spring 30.

In the further opening movement of the drawer 1, the second lever 23 is pushed back against the compression spring 30, wherein the latching nose 28 can not come into contact with the mating contour 29, but in a z. B. groove-like release on the lever arm 20 dips. With the retraction or displacement of the second lever 23 in the direction of the arrow P5 is the

Secondary energy storage or the compression spring 30 loaded or

squeezed accordingly. As a result, the lever 23 until reaching the highest point on

Guideway portion 25b, the furthest inside

lying point of the guideway 25 corresponds to fully inserted according to FIG. The contact roller 21 is already no longer in contact with the panel 12, so that the ejection process takes place in this phase alone on the contact of the second lever 23 with the guide track 25.

Accordingly, with the further opening operation, of which a snapshot Figure 7 shows, by the increased pressure force on the second lever 23 due to the compressed

Compression spring 30 and by the interaction with the

Outside the drawer 1 receding curve of the guideway portion 25c causes the ejection operation of the drawer 1 is supported. The drawer 1 experiences a movement component to the front, the

Compression spring 30 pushes the second lever 23 forward and presses against the guide track section 25c. A pivoting of the ejection lever 8 does not take place, since the

Spiral spring 19 is correspondingly strong and holds the ejection lever in the maximum pivoted position of the ejection lever 8 according to FIG.

At the clamping wedge 9 is on one of the guideway 25th

opposite narrow side another guideway with a tread 31 with consistently flat or straight

Course exists, the plant and to unroll the Support rollers 32, 33 is used.

The further ejection movement support by the second lever 23 or the compression spring 30 is indicated according to FIG. 7 or according to the movement arrows P3 and P8 (moving out of the lever 23).

Figure 8 shows a stoppage position of the drawer 1 relative to the furniture body 2 after the ejection process, what next

Friction influences by the interaction between the second lever 23 and the guide rail 25 is determined. The second lever 23 is pushed out and the maximum

Contact roller 24 in a trough-like lowered or concave portion of the guideway 25 and am

Guideway section 25e caught. If, in this state, no action is exerted on the drawer 1 from outside, for example by a user, the drawer 1 remains partially open in this position. An ejection distance b (FIG. 8)

including closing gap 13 can be specified by the mounting position of the clamping wedge 9 on the drawer 1.

The ejection movement of the drawer 1 is defined at

Position, namely at the track portion 25e

stopped.

In accordance with Figure 8 position of the drawer 1 is the

Invention advantageous. Is then by manual operation or by hand force the drawer 1 in

Direction P3 pulled forward (Figures 9 to 12), or again inwardly according to arrow PI pressed (Figures 13 to 17), the force memory 19 is forcibly loaded, the

Ejector 8 counterclockwise to the

Locking position according to Figures 1 and 2

is pivoted back.

When the drawer 1 is opened further from the position according to FIG. 8, a relatively short rising guideway section 25f and a guideway section 25g with an almost linearly rising course come into effect one after the other. This will be causes a small pivoting movement of the second lever 23 about the pivot axis S2, whereby the second lever 23 is slightly offset in the clockwise direction according to arrow P5 and in the

Arresting position of the second lever 23 on the ejection lever 8 passes (Figures 9 and 10). By further pulling out of the drawer 1 in the direction P3, is now by the rising edge of the clamping wedge 9 in the guideway portion 25g of

Ejection lever 8 is moved counterclockwise (Figures 11 and 12) and placed in its locked position on the base plate 7. The drawer 1 is then at least almost

completely open, over the guideway portion 25h a guide of the contact roller 24 on further opening

provided.

For the ejection lever lock on the touch-latch assembly 17 is a back on the ejection lever 8 of

Contact roller 21 trained approximately heart-shaped curve 34 or web formed. The curve 34 is at two

Portions for an inlet and an outlet of the spring tongue 22a of the tentacle 22 open, which is realized with a guide wedge 35, at its wide end a V-shaped

Rest stop 36 is formed. In the locked state of the ejection lever 8, the spring tongue 22a is held captive at the latching point 36 and urged under bias into the latching point 36. Along the curve 34 of the tentacle 22 and the tentacle downwardly projecting spring tongue 22a is locked and locked, under the action of the coil spring 19, the spring tongue 22a is pressed into the latching point 36, so that the ejection lever 8 is biased and the position according to Figure 1 or Figure 2 already in the open position of

Drawer 1 occupies. The predetermined in the final phase of the pivoting back of the ejection lever 8 by the curve 34 deflection about the axis S3 of the tentacle 22 with the achievement of

locked position at the rest stop 36 indicates the

Movement arrow P6 in Figure 12 at.

Figure 13 and the following figures 14 to 17 show a

Sequence of successive snapshots of the drawer 1 as they pass through a user in Closing direction PI, starting from the complete

ejected drawer 1 according to Figure 8. In this case comes to the drawer 1 fronseitige main section 25a to 25d of

Guideway 25 in contact with the contact roller 24 of the second lever 23. As already explained above for closing, the second lever 23 initially assumes a locked position on the ejection lever 8 due to the guide track section 25d. in the

Connection is made by further impressions of the drawer 1 a pivoting back of the ejection lever 8 about the pivot axis S according to arrow P9 and thus a tensioning of the coil spring 19 according to the figures 10 to 12. This controlled movement coupling the movement of the drawer 1 and the ejection lever 8 by the interaction of the second lever 23 and the

Guideway sections 25c and 25b achieved.

Here as well, when the ejection lever 8 is pivoted back, the touch-latch arrangement 17 is used as explained above. FIG. 16 indicates the directionally guided deflection of the catching arm 22 in the clockwise direction (movement arrow P7) when the

Spring tongue 22a abuts the guide wedge 35 and it

slides along and after an abutment on a concavely curved portion of the curve 34, the swinging back is completed and the ejection lever 8 deflects forward and the

Locking position is achieved according to Figure 2, wherein the tentacle arm 22 under the action of the coil spring 37 pivots slightly counterclockwise (movement arrow P10) in the latching point 36 and is trapped there.

The further movement of the drawer 1 in the closing direction by a user must be done only until the ejection lever 8 is locked, the drawer 1 then usually not yet completely closed. In the following last

Movement section when closing the drawer 1 approximately starting at the position shown in Figure 17 can then pull a drawer, not shown, the drawer 1 in the fully closed position relative to the furniture body 2 under a predetermined force.

FIG. 12 shows the tentacle 22 mounted under prestressing can be seen with a coil spring 37, the pressure at its beginning on the tentacles at the height of the pivot axis S3 attaches and is fixed relative to the furniture body 2 with its other end. The arrangement of the tentacle 22 is designed such that in the initial state or in the uninfluenced by the curve 34 state z. B. according to Figure 4, the tentacle 22 with its longitudinal axis parallel to the longitudinal axis L and

Direction of movement of the drawer 1 is in both

Pivoting directions, however, a small deflection is possible, wherein in the deflection state on the tentacle 22 each one

Restoring force is set in the initial state by means of the coil spring 37.

Finally, FIG. 18 shows very schematically two

basically possible to distinguish motion schemes I and II with movement phases 1.1 to 1.4 and a free

Movement possibility 1.5 a drawer or the drawer 1 with the furniture device according to the invention 3. In this case, an arrowhead indicates a direction of movement of the drawer in the respective movement phase. In addition, as described above, automatic retraction for fully closing the drawer in a closed state of the drawer is present.

The vertical line A defines a plane of a front or the front of the panel 12 of the drawer 1 in the closed and unactuated state on the furniture body 2, to the left of which is the area of the furniture body or the closing gap or right of it an area in front of the front side associated furniture. The vertical line B defines a plane of the

Front of the panel 12 of the drawer 1 in the fully open state on the furniture body. 2

In the movement scheme I, which includes the further opening of the ejected drawer, the movement section 1.1 means the triggering of the touch-latch arrangement over a comparatively short push-in distance in the direction of the furniture carcass or in the direction of the arrow to the left. The subsequent movement section 1.2 shows the ejection to the right up to an ejection point C over a larger leg of the total possible

Opening distance, which is determined by the distance between A and B. The movement section 1.3 relates to

Moving the drawer, in the movement scheme I by pulling on the drawer by a user and thus the tensioning of the ejection force memory. The movement section 1.4 indicates the Einziehwirkung the automatic feed in the closing direction of the drawer to the left.

In the movement scheme II, the movement phases 1.1 and 1.2 are identical to the movement scheme I. After ejection 1.2, the further movement of the drawer by a user but in the closing direction 1.3 to the left under the tensioning of the energy storage. The effect of the automatic feed mechanism 1.4 is set here when the drawer is inserted a little further, that is slightly offset to the left end point or arrowhead of the movement phase 1.3, but can also be done immediately afterwards.
