Description

The present invention relates to a device according to claim 1 and a furniture according to claim 14.

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 telescopically movable slide rails, on a furniture body displaced is guided. For a comfortable handling of the furniture part this can be moved with the help of an energy 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 be pushed or ejected by the influencing device usually over a section of a maximum possible or zurücklegbaren distance between a closed position and a fully open on the furniture body open position. Subsequently, after the furniture device caused by reaching a partially open position of the furniture part, the furniture part by the user manually moved comfortably.

For a next ejection process of the ejecting at least partially discharging energy storage must be reloaded 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 the energy storage device, it is also necessary to avoid spontaneous moving out of the furniture part or to secure the 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 advantageously take place by the action of the user on the furniture or the movable furniture part, 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, wherein the furniture part is movable via guide means for a guided movement in an opening direction and in a direction opposite to the opening direction closing direction, wherein the device is a dischargeable Force accumulator and charging means for charging the energy accumulator comprises and wherein with the the furniture-mounted device, the furniture part by a discharge operation in which a discharge of the energy 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, so to speak, a driving force for the ejection process or an ejection movement of the movable furniture part is provided from a closed position 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 movable furniture part, a charging of the discharged force accumulator by moving the movable furniture part of the reached open position regardless of the direction of advancement of the furniture part done. In this case, reaching the open position is effected 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 possible via a fixed movement of the movable furniture part, to obtain a charging of a discharged force accumulator by the further movement of the movable furniture part. With other movements of the energy storage can not be charged, which is disadvantageous.

According to the invention, regardless of the direction of movement of the movable furniture part is always a charging of the energy storage, which is done by an intuitive operation of the furniture part. Since the unloaded state usually follows then a further, takes place with the advancing 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. In this case, it is generally the case that the further movement without changing the selected direction of movement or without a reversal of movement of the furniture part must take place until reaching the state of charge of the energy storage to load the energy storage in an uninterrupted process or effectively.

The arrangement according to the invention is also advantageous in terms of assembly. Because the installation is always the same, regardless of how the user would like to charge the energy storage. So far, generic furniture device must be mounted differently in different configurations and / or depending on a desired Auflademöglichkeit, 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 ejector lever is provided, wherein a pivoting movement of the ejection lever causes the movement of the furniture part in the opening direction under the action of the discharging force accumulator, wherein the ejection lever has an ejection section, which can be brought into abutment with the movable furniture part in plant and a displaceably mounted second lever of the ejection lever is present, which is in the ejection process, at least after a cancellation of the system of the ejection section on the movable furniture part with a moving part with the furniture part (1) in contact and is displaceable with the ejection operation in an engaged position on the ejection lever. The second lever is displaced in particular during the ejection contact of the ejection section on the furniture part and thus due to the kinetic energy of the furniture part in the engaged position. The energy storage device must be designed so that the kinetic energy of the furniture part is sufficiently high or to a desired extent. 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 forcibly released in the course of ejecting the furniture part, since the pivot 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 formed with a variable lever arm to the pivot axis and stored accordingly displaceable. The second lever remains after lifting the contact of the ejection portion of the furniture part at least as long in contact with the guideway until the energy storage is fully charged after its discharge again, which correlates usually held with the locked retracted pivoting position of the ejection lever.

Due to the interaction of the second lever and the guide track, the further movement of the furniture part after the ejection operation is coupled with the further movement of the ejection lever and in particular a loading phase of the energy store with the pivoting back of the ejection 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 energy storage. The energy storage preferably remains permanently via an effective lever to the pivot axis in engagement with 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 a pivoting back of the ejection lever in a second of the first pivot direction opposite direction recharging the discharged force accumulator takes place. According to the invention, it is ensured that, after the ejection process, the interaction of the furniture part in its direction-independent further movement leads to the pivoting back of 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. For the ejection section advantageously engages on a front side of the furniture part, which extends transversely to a direction of movement of the furniture part, 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 is structurally not possible. In contrast, the second lever can come into contact with the guide track, which extends along the direction of movement of the furniture part or, in particular, its depth.

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, the coupling of the movement of the furniture part with the stationary pivotable ejection lever is made.

But it is also possible that the guide track is formed on the guide means, in which case different sections of the guide means come into question. For example, if a rail guide used as a guide, such as a full extension with carcass, center and pull-out rail, the guideway may be present on one of the three mentioned rails. For example, on 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 coincides with the movable furniture part. When attaching the guideway to the center rail, the guideway moves z. B. slower than the slide rail or the movable furniture part.

If the guideway attached to the movable furniture part, different attachment points come into question. The guide track can be arranged, for example, on the underside of the movable furniture part, for example on 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.

Further, it is advantageous that a loadable secondary energy storage device is present, which acts on the second lever. Thus, the second lever can also support the ejection process by virtue of its force-transmitting cooperation with the guide track. In particular, in a predeterminable phase of the ejection movement of the furniture part on the secondary energy storage act a force for ejecting the furniture part. 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 is received biased by pressure spring means, such as a coil spring, the discharge lever. 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 ejection process 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 accumulator in a recessed position on the ejection lever or clamped.

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 guideway contacting part of the second lever between the pivot 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 a mitbewegter with the furniture part ejection lever and thus the pivot axis possible when the guideway z. B. is formed fixed position on the furniture body.

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 is arranged on the guide track during the ejection process when the ejection section no longer abuts the movable furniture part, so that the ejection effect with the second lever beyond the first phase is extendable. With the second lever so a contact time between the ejection lever and the movable furniture part can be extended in time, with otherwise comparable conditions.

This is advantageous because the second lever acts like an extension of the ejection effect of a simple ejection lever, for example as a Hebelarmverlängerung the lever arm formed with the ejection section, but this is not possible due to space or constructive in the rule. 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 other further movement of the movable furniture part from the position reached during the ejection operation causes a pivoting back of the ejection lever. 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.

Advantageously, in the mounted state of the device, the ejection lever and the force accumulator are designed coordinated with one another in such a way that a pivoting back of the ejection lever causes a charging of the force accumulator.

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 increases the tensile force acting on the ejection lever, which correlates with the stored force, 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 may be present on a so-called clamping wedge, wherein the clamping wedge may be attached to the movable furniture part optionally subsequently in one of several possible different attachment positions or removed again. The assembly component For example, it can be designed as a flat component with flat main sides and narrow sides, a section of the narrow sides forming the guideway. Another section of the narrow sides can also take over other 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. In this case, different sections of the guideway correlate with different pivoting positions of the ejection lever in the assembled state of the clamping wedge or the ejection device, due to the contact of the second lever on the relevant 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 guideway has a changing course for the installation of the second lever, with an intermediate portion and on both sides of the intermediate portion subsequent main sections. Depending on a position of the furniture part on the furniture, which changes with the guided movement of the furniture part, for example, depending on a sliding 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 distinguished between different contexts in the interaction of the second lever with the guideway. 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 energy storage is located 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 the secondary energy accumulator. In subsequent subsequent particularly rectilinear or zurückweichendem course of the first main section of the second lever of the contour of the guideway following the ejection lever is moved out under the action of the intermediate preloaded secondary energy storage and pressed against the guideway that a correspondingly directed and sufficiently large force acts on the furniture part, so that the furniture part undergoes a movement component in the opening direction and the ejection movement of the movable furniture part is supported. From the moment in which the ejection section in the last phase of the ejection process comes out of engagement with the furniture part, the pivoting position of the ejection lever remains essentially 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 an example, sink-like shape of the intermediate portion. The lower section in the intermediate section or recessed guide track has, for example, edge flanks or an inlet and outlet side at the intermediate section, via which the second lever can only be moved past, if a structurally predeterminable minimum force is applied to the furniture part in the opening or closing direction of the furniture part becomes. This can be done by an external influence on the furniture part by the user who manually further opens or closes the furniture part after the automated expiring ejection process.

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 guide track, when the furniture part is opened further, the second lever, controlled by the shape of the inlet and outlet side of the intermediate portion, is 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 arranged to the pivot axis of the ejection lever. Only when later canceling the contact between the second lever and the guideway, the locking position is canceled on the ejection lever again.

As the furniture part advances in the corresponding direction when the second lever is locked on the ejection lever, the guide track or its rising and / or in particular rectilinear flank presses against the detected second lever. In this case, the ejection lever is pivoted back against the action of the ejection lever-force accumulator. The force required for this purpose is applied to the furniture part with the action of the user, wherein the contact force substantially corresponds to the force for charging the force accumulator, since the proportion is negligible in addition to frictional forces to be overcome.

The guideway is further designed so that after a predetermined distance in the considered movement of the furniture part by the action of the user, which can make up for example, about a third or half of the total possible opening or closing distance of the furniture part, the ejection lever in his complete zurückgeschwenkte position is brought, at the end of this movement of the energy storage is again in its original or initial state of charge. The furniture part is usually completely open or completely closed. The pivoting back of the ejection lever as described above is achieved in particular by a reduction in the distance of the guide track of the main sections to the ejection lever arrangement or an imaginary parallel line to the direction of movement through 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 relevant 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 rests, 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 for the guideway to be tuned in such a way that the ejection lever occupies a position which is preferably maximally swung in relation to a starting position as a result of the bearing of the second lever on an intermediate section of the guideway. With or shortly before reaching the fully swung-out position, the ejection process, which until then was decisive for the ejection process, loses contact with the furniture part.

In principle, it is preferred if the guideway is formed without a step or a jump or an edge-like transition, but represents a continuous path. 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 seen from an outer region of the guideway to the intermediate portion sloping or formed with opposite inclination.

In principle, it is possible that at the end of the guide track to the overall length of the guide track comparatively short end portion of the guideway of z. B. 5 to 10% of the total length is present at which then the Connecting main sections, wherein the at least one end portion may be designed individually and, for example, allows a facilitated inlet or outlet of the second lever when contacting or leaving the guideway. The two main sections can in particular make up a substantial length of the guideway, for example, in each case 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 main section of the guideway moves along the second lever, wherein the ejection lever can be pivoted back in the direction of the pivoted starting position. 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 is designed for one of the two possible directions of movement of the furniture part following the ejection process. A first main section is responsible for further movement in the opening direction and a second main section for advancing in the closing direction of the furniture part 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 the closing direction 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. If the mounting component, for example, mounted on the movable furniture part and, for example, moved closer to a front, can be achieved that the furniture part is ejected less far after the ejection operation relative to the furniture body by the interaction of the ejection lever on the guideway than during assembly of the mounting member closer to one the front side opposite 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 the 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 is guided displaceably on the ejection lever 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 scenery or the slot, a portion of the second lever may be performed, for example, protrude a protruding engaging portion in a guideway, whereby a safe back and forth moving the second lever along the linear guide is possible.

Further, it is advantageous that the second lever is accommodated on the ejection lever such that the second lever arrives in a predeterminable relative position on the ejection lever in a latching position on the ejection lever, in particular by a pivoting movement. Moving into the latching position, in which the second lever is rigid on the Exhaust lever is locked available, only possible in the linear completely disengaged state of the second lever on the ejection lever. This ensures that otherwise the second lever for the support of the ejection process as explained above moves under the action of the secondary force accumulator along the guideway and in this way can adapt to the guideway with its contact section or come into contact with this. 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 of the ejection lever position, for example by a possible only in this position low pivoting relative to the ejection lever, so that while the locking position is reached. The need for this small pivoting can be done against the action of the secondary energy storage in the interaction of the second lever with the track, for example by the moving along by moving on of the furniture part 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, to which the force accumulator attaches 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 degree of functionality can be achieved with the ejection lever, in particular a plurality of operating systems with different mechanical characteristics, which can be operated separately with the respective lever arm, can be realized on the ejection lever or with respect to the common pivot axis. An active system relates, for example, to the interaction of the energy store 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 guide track. In addition, a multi-arm lever assembly for reasons of space is advantageous, especially since this is flat building transverse to a pivoting direction.

In the subject of the invention may also be provided a device for locking a movable member in a locking position and for releasing the lock, wherein the release of the lock is effected by a movement of the movable member against a force acting on the movable member and a movably mounted pivoting part is present with an engagement portion such that the pivoting part is caught in the locking position at a counter portion.

In this case, a spring element is provided, with a first end which acts on the pivoting part and with the free end opposite end, which is fixedly mounted, wherein the spring element exerts on the pivoting part, at least over a portion of the possibility of movement of the pivoting member 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 cooperate in the mounted state on the furniture in particular with an ejection arrangement 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 action of the force acting on the movable element or of the charged force accumulator, the now released movable element can act on the furniture part by its movement, so that the furniture part is moved out of a closed position or 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 assembly, for example, by a pressing against the furniture part ejection lever, acts on the power storage. In this embodiment, an indirect force effect on the movable element or the furniture part is realized by the energy storage 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, the ejection effect on the furniture part can be active only after the release of the locking of the movable element.

The movably mounted and biased received pivoting part has in particular 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, the pivoting part is caught on a latching contour section of the curve, wherein the locking position can be canceled by a directed relative movement between the latching contour section and the engagement section in the direction against the acting force on the movable element of a direction of moving out, so that the engagement element is released and guided guided along the curve 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 of the movable member, the engaging portion is then caught again under the action of the spring member on the curve at a curved portion formed therefor and the movable member is held in the locking position.

This is a particular space-saving and reliably acting device for locking a movable furniture part in a closed position and to release the lock predetermined.

The invention also relates to a piece of furniture with one of the aforementioned devices. In this way, the advantages already discussed above can be realized on a piece of furniture, in particular on a furniture carcass with a drawer slidably received on it.

The ejection lever 8 serves to eject the according to FIG. 1 and 2 closed drawer 1 or from a depressed position according to FIG. 3 , The ejection takes place in the opening direction relative to the furniture body according to movement arrow P3 of the drawer 1 (s. FIG. 4 ).

Furthermore, the furniture device 3 comprises a separate or separate from the base plate 7 and mitbeweg with the drawer 1 part, which is designed here as a mounting component or concretely as a clamping wedge 9. The also flat-fitting clamping wedge 9 is in the illustrated embodiment on the underside of the drawer bottom 1a 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 bearing a small clearance for the clamping wedge 9, for example, in the millimeter range is possible to allow for a sliding movement of the drawer 1 optionally an evasive movement of the clamping wedge 9 in particular transversely to the longitudinal direction L, so that the clamping wedge 9 and thus the drawer 1 when moving can not jam what might otherwise happen due to assembly and / or component tolerances. When moving the drawer 1 are 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 an end face 31 on the clamping wedge. 9

The drawer 1 comprises a front panel existing aperture 12, which in the closed state according to FIG. 1 and 2 with its directed to the furniture body 2 inside a closing gap 13 is limited, which forms between the inside of the aperture 12 and front side existing end faces 14 and 15 of the side walls 2a and 2b. 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 FIG. 2 , which presses against the diaphragm 12 inside, also 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 according to FIG. 1 and 2 held by a device according to the invention in the closed position, which is designed as a touch-latch assembly 17. It is according to FIG. 2 the ejection lever 8 is received in the recess 7a and thereby locked in a pivoted-back position, so that a front side 8a of the lever arm 20 is positioned within an imaginary rectangular border of the base plate 7. 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 diaphragm 12 ejection lever 8 must be pivoted by a Mindestschwenkweg or by a few degrees 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 impressions of the drawer 1 in the closing direction according to the arrow P1 for releasing or releasing the locked position is carried out until the abutment of the diaphragm 12 at the end faces 14, 15, what FIG. 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, in the basic state of the furniture device 3 according to FIG. 1 and 2 in the longitudinal direction L, has at its free end an attachment point for a trained as a spiral spring 19 energy storage. The coil spring 19 forms a primary energy storage or superordinate or dominant energy storage of the furniture device 3. The coil spring 19 is in the ground state according to FIG. 1 and 2 relatively tight and thus loaded the energy storage. When triggering the ejection process by pushing in the drawer 1 ( FIG. 3 ), the coil spring 19 is stretched only slightly further.

With the effective tensile force generated by the coil spring 19 on the ejection lever 8, this is pivoted clockwise after its locking release ( FIG. 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 arrangement 17 or its triggering by pressing the drawer 1 in the closing direction according to arrow P1 will be explained below. With the impressions and thus the small pivoting back of the ejection lever 8 is a catching 22 with spring tongue 22 a ( FIG. 12 ) trained engaging 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 pivotally mounted catching arm 22 by the spring tongue 22 a is guided along or guided along the curve 34.

FIG. 4 shows the front portion of the arrangement according to the Figures 2 and 3 in an already slightly pushed-state of the drawer 1 in the ejection process by swinging the ejection lever 8 according to the direction P4 by contracting the biased coil spring 19. In this case rotates about the axis S1 rotatably mounted contact roller 21 of the lever arm 20 over an area inside along the aperture 12. Die Drawer 1 moves characterized according to arrow P3 or in the opening direction of the drawer 1 from the furniture body 2 out.

FIG. 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 trained as a compression spring 30 secondary energy storage, comes with its front free end by a contact roller 24 there existing in abutment with a guide track 25 , The guideway 25 is present on an inwardly directed narrow or end face of the clamping wedge 9. 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. In this case, the furniture device 3 is tuned or it is constructive that almost at the same time or only with a comparatively small time or movement offset the contact roller 21 with the inside of the aperture 12 is 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 received via a linear guide relative to the ejection lever 8 preferably on the second lever arm 20 movable. The linear guide comprises a slot 26 in the second lever arm 20, in which a pin element 27 (not visible) secured therein or guided is engaged on the second lever 23. 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 moved linearly along the linear guide, but it can in an extended by the compression spring 30 at least almost fully extended in the linear guide position according to z. B. FIG. 3 . 9 or 13 , Be slightly deflected about a pivot axis S2 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 FIG. 9 or 13 by laying a correspondingly shaped guideway section 25f ( FIG. 9 ) or 25d ( FIG. 13 ) of the guideway 25 pivots slightly, which is indicated by the movement arrow P5 in FIG FIG. 9 and 13 is indicated, engages a formed in the front portion of the second lever 23 Einrastnase 28 in a matched or appropriately designed corresponding counter contour 29, for example, a latching notch, the second lever 23 is then fixed in this position when it is still pressed, that the second lever 23 can not perform a linear movement along the slot 26. Once the second lever 23 is no longer is pressed or is no longer in contact with the guideway 25 or at least not in a suitably directed Andrückkontakt with the guideway 25, by the rear or rearward on the lever 23 andrückende compression spring 30 a directed moving out of the second lever 23 from the mating contour 29 causes and thus repealed its fixation. For this purpose, a laterally offset to the pivot axis S2 engagement 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 FIG. 4 is the second lever 23 by the contact with the clamping wedge 9 counterclockwise so according to the arrow P4 in FIG. 4 and deflected away from the mating contour 29 and thus securely prevents a catch. Thus, the lever 23 can be pushed in linearly or by the compression spring 30 forward or opposite to the direction P6 ( FIG. 5 ), this being possible only to the extent that the guideway 25 allows the second lever 23 to move out along the slot 26.

Now starting from FIG. 4 the ejection lever 8 is pivoted further forward according to P4 and the drawer 1 is ejected, a guide track portion 25b curved inwardly or transversely to the longitudinal direction urges the second lever 23 in the direction of the arrow P5 along the slot 26 so that the second lever 23 is retracted on the second lever arm 20 against 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, lead to the effect as described.

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

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 of the secondary energy storage or the compression spring 30 is loaded or compressed accordingly. As a result, the lever 23 until the highest point on the guideway portion 25 b, which corresponds to the innermost point of the guideway 25, according to FIG. 6 fully inserted. 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 process, of which a snapshot FIG. 7 shows, caused by the increased pressure force on the second lever 23 due to the compressed compression spring 30 and by the interaction with the receding to the outside of the drawer 1 curve of the guideway portion 25c that the ejection operation of the drawer 1 is supported. The drawer 1 experiences a movement component to the front, wherein 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 coil spring 19 is correspondingly strong and the ejection lever in the maximum swung-out position of the ejection lever 8 according to FIG. 6 holds.

On the clamping wedge 9 is on one of the guideway 25 opposite narrow side another guideway with a tread 31 with consistently flat or straight course available to the plant and to unroll Support rollers 32, 33 is used.

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

FIG. 8 shows a stoppage position of the drawer 1 relative to the furniture body 2 after the ejection process, which is determined in addition to friction influences by the interaction between the second lever 23 and the guide track 25. The second lever 23 is pushed out to the maximum and the contact roller 24 caught in a trough-like lowered or concave portion of the guideway 25 and the guideway portion 25 e. 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 width 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 stopped at a defined position, namely exactly at the guide track section 25e.

In accordance with FIG. 8 Position of the drawer 1 uses the invention advantageous. Is then pulled by manual operation or by manual force the drawer 1 in the direction P3 forward ( FIGS. 9 to 12 ), or pushed back inwards according to arrow P1 ( FIGS. 13 to 17 ), the force accumulator 19 is forcibly charged, the ejection lever 8 counterclockwise to the locking position according to the FIGS. 1 and 2 is pivoted back.

When opening the drawer 1 from the position according to FIG. 8 comes successively first a relatively short rising guideway portion 25f and a guideway portion 25g with almost linearly rising course to effect. 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 locking 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, the ejection lever 8 is now moved in the counterclockwise direction by the rising edge of the clamping wedge 9 in the guide track section 25g ( Figures 11 or 12) and brought into its locked position on the base plate 7. The drawer 1 is then at least almost completely open, wherein a guide of the contact roller 24 is provided on further opening of the guide track section 25h.

For the ejection lever lock via the touch-latch assembly 17 is formed on the ejection lever 8 rearward of the contact roller 21 formed approximately cardio-curved curve 34 or web. The curve 34 is open at two portions for an inlet and an outlet of the spring tongue 22a of the tentacle 22, which is realized with a guide wedge 35, at its broad end a V-shaped latching point 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 detent 36, so that the ejection lever 8 is biased and the position according to FIG. 1 respectively. FIG. 2 already in the open position of the drawer 1 occupies. The predetermined in the final phase of the pivoting back of the ejection lever 8 by the curve 34 deflecting about the axis S3 of the tentacle 22 with the reaching of the locked position at the latching point 36, the movement arrow P6 in FIG. 12 at.

FIG. 13 and the following FIGS. 14 to 17 show a succession of consecutive snapshots of the drawer 1 as they pass through a user Closing direction P1, starting from the fully ejected drawer 1 according to FIG. 8 , Here, the drawer 1 fronseitige main section 25a to 25d of the guideway 25 comes into contact with the contact roller 24 of the second lever 23. As already explained above for closing, the second lever 23 first assumes due to the guideway portion 25d a locked position on the ejection lever 8 a. Subsequently, by further pressing in of the drawer 1, a swinging 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 FIGS. 10 to 12 , This controlled movement coupling of the movement of the drawer 1 and the ejection lever 8 is achieved by the interaction of the second lever 23 and the guide track sections 25c and 25b.

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 a clockwise direction (movement arrow P7) when the spring tongue 22a abuts and slides along the guide wedge 35 and, after abutting a concavely curved portion of the curve 34, the swinging back is completed and the ejection lever 8 deflects forward and the locking position according to FIG. 2 is achieved, 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 according to FIG. 17 For example, a retraction automatic, not shown, can then pull the drawer 1 into the completely closed position relative to the furniture body 2 under a predeterminable force.

Out FIG. 12 is the tentatively mounted tentacle 22 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 FIG. 4 the tentacle 22 with its longitudinal axis is parallel to the longitudinal axis L or to the direction of movement of the drawer 1, in both pivoting directions, however, a small deflection is possible, wherein in the Auslenkzustand on the tentacle 22 each a restoring force is set in the initial state by means of the coil spring 37.

FIG. 18 finally shows very schematically two basically possible to be distinguished movement 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 side 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 greater distance of the entire possible opening distance, which is determined by the distance between A and B. The movement section 1.3 relates to the further movement of 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.
