Description

State of the art

Devices for influencing the movement of a furniture part that is movably accommodated on a furniture body via guide means or correspondingly equipped furniture are known. The guiding means, for example for guiding linearly displaceable drawers and the like or pivoting doors or flaps, can comprise two guiding units which act in the same way and are spaced apart from one another.

Two parallel guides are used to guide the movement of a drawer, for example, relative to the fixed furniture body.

A guide can be designed as a so-called full or partial extension with rails that can be moved telescopically relative to one another, with a fixed rail or fixed rail relative to the furniture body and a movement or extension rail assigned to the movable furniture part being available, with the full extension also having a middle rail acting in between.

When ready for operation, the movement rail is detachably connected to the movable furniture part, so that the furniture part can be moved back and forth relative to the furniture body in the opening direction or in a closing direction opposite thereto.

The movement can, in particular, be carried out manually by a person acting on the furniture part or possibly supported by a drive with a tensioned spring arrangement.

A usable volume of the piece of furniture that is present within the piece of furniture or the body of the piece of furniture, in particular for accommodating Objects are in a closed position of the furniture part relative to the furniture body, ie when no access to the interior of the furniture part is possible, inaccessible or covered by the walls of the furniture part and/or the furniture body. In the closed position, in particular, only one front side of the furniture part is freely accessible from the outside of the furniture. In an open position of the furniture part that is partially or fully opened from the closed position by a movement of the furniture part in the opening direction, the useful volume is more or less accessible.

In addition, adjusting means for specifying the closed position of the movable furniture part relative to the furniture body are known. Such a device is for example in EP 2 279 680 A1 shown.

In this way, for example, a front image can be set on a front side of the piece of furniture in such a way that the front side or front side of the furniture part is aligned flush with adjacent furniture sections in the closed position. The adjustment takes place in the millimeter range, so that the closed position of the furniture part relative to the furniture body is retained.

In order to unlock or release the furniture part from the closed position, which is usually secured, and to enable a subsequent opening movement, both guides usually have to be released or released simultaneously or in the same way. A triggering path that has to be bridged in the closing direction is required on both guides.

In order to operate both guides in the same way, regardless of the location of the force acting on the furniture part when it is triggered, transmission means are provided which act in a synchronizing manner between the two guides. Such a device is, for example, from EP 1 314 842 A1 known.

Object and advantages of the invention

The object of the present invention is to improve the functional and operating safety of the devices described in the introduction or corresponding furniture, in particular with regard to the triggering situation of a furniture part in the closed position.

This object is solved by the independent claim.

The dependent claims show advantageous variants of the invention.

The invention is based on guide means for guiding the movement of a furniture part that is movably received on a furniture body via the guide means, so that the furniture part can be moved in regular operation over a movement path relative to the furniture body in such a way that, depending on the position along the movement path, a useful volume on the furniture part and/or is accessible on the furniture body or the useful volume is covered when the furniture part is in a closed position in a stationary position relative to the furniture body, the guide means comprising two guide units spaced apart from one another and acting in the same way, each guide unit having a movement rail that can be assigned to the furniture part and a body rail that can be assigned to the furniture body, the movement rail and the body rail of each guide unit can be displaced relative to one another, each guide unit having a device with transmission means, the device having an ejection arrangement for ejecting the furniture part from the closing position in an opening direction and a retraction arrangement for retracting the furniture part into the closed position, wherein in the assembled state of the furniture part to release the closed position of the furniture part the transmission means for a synchronous displacement movement of the two movement rails are present, wherein the Offsetting movement takes place by moving the furniture part from the closed position in a closing direction, and the device has adjustment means for specifying the closed position of the movable furniture part relative to the furniture body, with which the furniture part can be adjusted while maintaining a closed position along the direction of movement provided by the guide means.

After a triggering action, for example by pressing the furniture part a small distance in the closing direction, the furniture part can be moved out of the closed position in the opening direction, which can be done manually and/or by an opening device.

The essence of the invention lies in the fact that the adjustment means are designed in such a way that the position of a counter-element of the transmission means is adjusted when the closed position of the movable furniture part is adjusted, so that the function of the transmission means remains unchanged when the position of the counter-element is adjusted.

With the invention, the reliable functioning of the transmission means can advantageously be maintained in all possible settings of the position of the furniture part relative to the furniture body in the closed position.

So far, this has not always been possible or only partially possible. This is because, particularly in the case of larger, for example maximum possible adjustment paths that are bridged by adjusting the position of the closed furniture part, a relative movement of parts of the transmission means associated with the adjustment may mean that the transmission means no longer function or no longer functions in the desired manner given is. In the negative case, this can lead to a failure of the function of the transmission means, so that a furniture part secured in the closed position may not can be unlocked. Such a scenario is prevented according to the invention.

This is because the function of the transmission means is not changed when the closed position is adjusted, since these are also adjusted at the same time.

Otherwise, it has so far been possible that a triggering path of the closed furniture part due to an action on one side of the front side of the furniture part only leads to the triggering or unlocking of the guide of the two guides that is closer to the point of action and the other guide does not trigger because the means of transmission no longer work. However, the furniture part that is connected to both guides can only be moved out if both guides are triggered in the same way or synchronously, otherwise the furniture part remains in the closed position secured by the non-triggered guide.

The position of the transmission means is also adjusted on that part of the transmission means which is not accommodated on the movement rail. It is advantageous here that all affected parts or components are adjusted accordingly, in particular identically. The transmission means comprise cooperating elements such as a contact element on the movement rail and a counter-element on the carcass or fixed rail which interacts with the contact element. With the setting, according to the invention, the counter-element is set or adjusted in accordance with the adjustment of the contact element that is present on the movement rail.

The contact element itself, which is present on the movement rail, with the furniture part being in the closed position by a corresponding adjustment of the movement rail, does not have to be set separately, since it is adjusted with the furniture part or the movement rail. the The device according to the invention is designed in such a way that the counter-element on the carcass rail is set or readjusted in a correspondingly predeterminable manner, in particular in the direction and amount corresponding to the adjustment of the furniture part or the contact element.

The device comprises an ejection arrangement for ejecting the furniture part from the closed position in an opening direction and a retraction arrangement for drawing the furniture part into the closed position.

The ejection arrangement and the retraction arrangement are preferably present on the guide, in particular a basic component with essential components of the two arrangements can be detachably attached to the carcass rail, with interaction with the movement rail for ejecting or opening and retracting the movable furniture part on a last partial path until it is reached the closed position is set up. Elements or sections adapted for this purpose are formed on the guide or the movement rail.

The basic component can be attached, for example, to a horizontally extending section of the body rail, with a comparatively small distance adjacent to sections of the movement rail.

To provide a force for ejecting or retracting the furniture part, there is a mechanical energy accumulator that can be alternately charged and discharged for the ejection arrangement and the retraction arrangement, in particular with a spring arrangement, for example with a spiral spring. After the triggering action or unlocking of the closed position of the furniture part, the ejection energy storage device of the ejection arrangement present in the charged state causes the furniture part to be ejected over a first section in the opening direction, with the ejection energy storage device being at least partially discharged. The pull-in energy store Pull-in arrangement serves in particular to pull in the furniture part from a partially open position relative to the furniture body into the fully closed closed position during a movement in the closing direction. During this process, the pull-in energy store is also at least partially discharged.

The charging of the respective energy accumulator, which is necessary before it can be used again, takes place in particular in connection with movements of the furniture part in the opening or closing direction that take place during regular operation by means of the guide means when the furniture part is used by a person, for example by opening the furniture part further after it has been ejected with the ejection arrangement.

It is also advantageous that the adjustment means are designed so that the position of the transmission means is set and the closed position of the movable furniture part is adjusted relative to the furniture body to the same extent and/or in the same direction. This ensures that, based on a predetermined optimal functional situation of the transmission means existing before the closed position is adjusted, this reliable function of the transmission means is also fulfilled after the closed position adjustment.

The adjusting means are designed in such a way that after the closed position of the movable furniture part has been adjusted relative to the furniture body, the functional situation of the transmission means is exactly the same as before the closed position was adjusted. For an initial assembly situation of the movable furniture part on the furniture body via the guide means, only an optimal functional situation of the transmission means must be set up, the exact closed position relative to the furniture body advantageously not being taken into account got to. The invention can also advantageously be used to that based on an initial assembly by a specialist, from which it is assumed that an ideal situation of the transmission means is provided, when the closed position of the furniture part is later adjusted, there is no change in the previously established ideal function of the transmission means. This means that a front image on the furniture can be corrected quickly and easily later on.

The closed position of the movable furniture part can be adjusted, for example, without tools or with a tool, for example by simply rotating the adjusting means in two different directions, with the furniture part being able to move in the opening and closing direction relative to the furniture body, in particular together with the movement rail, for example by a maximum infinitely adjustable by a few millimeters.

Furthermore, it is advantageous that the adjusting means are designed so that the position of the transmission means is adjusted and the closed position of the movable furniture part is adjusted relative to the furniture body with a step-up or step-down.

In particular, the increase or reduction is comparatively small. This allows the function of the transmission means to be adapted depending on the closed position of the movable furniture part. For example, it is conceivable that depending on the closed position of the furniture part relative to the furniture body, a slightly different displacement path is provided for parts of the transmission means. The adjusting means are designed in such a way that the function of the transmission means is reliably guaranteed in all possible closed positions that can be set up by adjustment.

The closed position of the movable furniture part is adjusted by adjusting a mechanical stop relative to the furniture body Specifies the closed position of the furniture part. The stop can be movably adjusted in particular in the closing or opening direction of the furniture part. The stop can preferably be moved back and forth via a sliding fit. For example, the closed position of the furniture part defined with the retraction arrangement is determined via the position of the stop in that a catch element, which can be temporarily coupled to a section of the furniture part guide element or the movement rail, is pulled against the stop under the action of the retraction energy store and there is pending. Accordingly, the stop acts as a movement stop for a section or part of the retraction arrangement that is acted upon and displaceable by the retraction energy storage device and that is present on the carcass rail except for a catch element on the movement rail. The catch element is in particular protruding on an outside of the movement rail and is coupled over a partial movement path of the movement rail to the part acted upon by the force accumulator, for example a ratchet part.

An advantageous variant of the subject of the invention is characterized in that there is a ratchet part with which a catching element present on the furniture part guide element interacts in the closed position of the furniture part, the ratchet part being under the effect of a retraction force storage device. In particular, the latch part is pressed against the mechanical stop in the closed position.

The pawl part, which is particularly slidably mounted, is used for the temporary connection between the movement rail and the retraction energy storage device in order to retract the furniture part on a final partial path before the closed position is reached with the force of the retraction energy storage device. In the closed position of the furniture part, which is then at a standstill, the latch part rests against the stop and is blocked against movement in the direction of wear. The pull-in force accumulator continues to act on the with its remaining stored force Latch component and keeps it pressed against the stop. Since the pawl component is coupled to the catching element of the movement rail, the movement rail and thus the furniture part are held or secured in the closed position under the effect of the residual force of the pull-in energy store.

With the adjustment of the stop in the retracted position, the furniture part is also adjusted in the closed position. The pawl component is blocked in its retracted position in the closing direction, but is mounted in such a way that the pawl component can deviate laterally during a later release movement of the furniture part together with the furniture part guide element that is moved along with it, and the connection with the catch element or the furniture part is broken. This is achieved by pressing the closed furniture part a few millimeters in the closing direction, with the catch element acting on the latch part in such a way that it deflects sideways and the catch element is decoupled from the latch part. The now freely movable furniture part is moved forwards or in the opening direction by the charged ejection energy storage device, which acts prestressed in the opening direction against the furniture part guide element, but is weaker than the residual force of the retraction energy storage device.

An actuating part of the device can be adjusted in two opposite directions, with the actuating part being coupled to the mechanical stop. Preferably, the control part can be mounted displaceably on the carcass rail and is designed as a sheet metal part on which the stop is present and with which a part of the transmission means assigned to the carcass rail interacts.

An advantageous embodiment of the invention is characterized in that an exemption section is present, which in the closed position of the furniture part allows an evasive movement for a counter-element, so that the closed position of the furniture part can be canceled Release section is also adjustable with the adjustment of the closed position of the movable furniture part. The release section is advantageously connected to the stop. The release section allows the pawl part to deviate laterally in the closed position of the furniture part that is up against the stop and thus eliminate the pull connection of the pull-in energy store on the furniture part.

In particular, both the stop and the release section for an evasive movement of the latch part are present on the actuating part. The control part, the stop and the release section can be formed by different components that can be releasably connected to one another. The release section is attached to the stopper or the part on which the stopper is provided. The lateral escape route provided by the release section for the latch part can be designed in the manner of a slotted guide.

For the latch part, the release section provides, in particular, a lateral escape route for the latch part's evasive movement transversely to the closing or opening direction of the furniture part when the latch part is in contact with the stop. The associated interaction of the pawl part and the release section can take place, for example, by means of at least one protruding section on the pawl part, the section engaging in a suitable recess on the release section that serves as a guide.

In particular, the release section includes the link guide for the latch part in the stop position on the stop.

It is further proposed that, according to an advantageous embodiment of the subject matter of the invention, the adjustment means comprise a rotary adjustment. For example, this can advantageously be done with a turning tool. The rotary adjustment can be done like this be positioned in such a way that the twisting can take place without any problems, for example when the furniture part is in the open position relative to the furniture body. The rotary adjustment can B. include a worm thread, which is rotatable about a fixed pivot point and which meshes with a counter-section, for example, on the control part.

It is also proposed that the device is advantageously designed for a detachable, tool-free attachment to the guide unit.

The transmission means are advantageously coupled to the actuating part and the release section in such a way that when the closed position of the movable furniture part is adjusted, the release section and the transmission means are adjusted together. With the adjustment, all relevant parts are also adjusted, whereby the functionally correct interaction of the parts is retained.

In addition, there is a guide unit for guiding the movement of a furniture part relative to a furniture carcass with a movement rail that can be assigned to the furniture part and a carcass rail that can be assigned to the furniture carcass, the movement rail and the carcass rail being displaceable relative to one another, with an ejection arrangement for ejecting the furniture part from the closed position in an opening direction and a retraction arrangement for retracting the furniture part into the closed position. According to the invention, there are two guide units. If necessary, a middle rail acting between the movement rail and the body rail can also be provided. The guide unit can be designed as a rail guide, in particular as a so-called full extension for drawers and the like. The essential aspect of the guide unit according to the invention is that the ejection arrangement and the retraction arrangement in the direction of movement of the rail relative to Cabinet rail viewed from each other, offset and fixed in position on the guide unit. The ejection arrangement and the retraction arrangement can thus be provided on the guide unit in a particularly space-saving and compact manner. The two units are preferably present on a horizontally extending section of the carcass rail. The ejection arrangement is designed in particular as a touch-latch device or is provided with a touch-latch functionality. The feeder arrangement comprises in particular two carriers on the movement rail, which interact with opposite sections of the feeder arrangement on the carcass rail depending on the displacement position of the two rails relative to one another or depending on the displacement direction of the moving movement rail. In particular, the retraction arrangement has a pivoting pawl, which is coupled to a spring of the retraction arrangement that serves as an energy accumulator. The pivoting pawl is advantageously provided laterally to the ejection arrangement and/or a damper of the retraction arrangement.

A further essential aspect of the invention is that the guide unit for guiding the movement of a furniture part relative to a furniture body has a device for influencing the movement of the furniture part in one of the configurations defined above. For example, components of the device can be detachably attached to the guide unit.

The device for influencing the movement is advantageously present on the body rail or on the movement rail. Attaching at least parts of the device to the furniture body and/or the movable furniture part is not excluded.

The invention also relates to a piece of furniture with a piece of furniture that is movably accommodated on a piece of furniture via the guide means, with a device according to one of the above mentioned training is provided.

This is how the advantages explained above can be set up in a piece of furniture. In particular, a uniform front image with front sides aligned with one another can be set up particularly advantageously for a piece of furniture that has a plurality of furniture parts in the furniture body. Because of component or assembly tolerances, when the furniture is assembled for the first time, it is usually the case that the front sides of the various furniture parts in the furniture body are slightly offset from one another in the direction of movement of the furniture part. With an adjustment using the device according to the invention for influencing the movement of a furniture part, the front image of the furniture part can then be adjusted without any problems.

Further advantages and features of the invention are explained in more detail with reference to an exemplary embodiment of the invention that is shown in a partially schematic manner in the figures. In detail shows:

• Figure 1 to Figure 5

• figure 9
  an enlarged detail of a unit of the device according to the invention from above.

The arrangement shown in the figures comprises a device according to the invention, designed as a furniture part device 1, for influencing the movement of a furniture part, which relates to a drawer (not shown) in the figures. The drawer can be moved relative to a furniture body, also not shown, with two similar telescoping guides. figure 1 shows the furniture component device 1 on a guide 2 which comprises a body rail 3 , a center rail 4 and a drawer rail 5 . The carcass rail 3 can be fixed in position on the inside of a wall of the furniture carcass, with the drawer rail 5 being present below a base of the drawer and being detachably connected to a rear area of the drawer via a hook 6 on the drawer rail 5, so that the drawer rail 5 together with the drawer can be moved back and forth to a limited extent according to the arrow P1 in the opening direction or according to the arrow P2 in the closing direction.

On the guide 2 there is a known retraction arrangement 7 with a retraction energy store designed as a spiral spring 8 for retracting the drawer rail 5 into a closed position according to FIG figure 1 present. In the closed position, in the mounted operating state, the drawer is held in the closing direction P2 relative to the furniture body under the effect of a tensile force remaining after retraction by the spiral spring 8 .

Furthermore, there is no closer to the cabinet rail 3 visible ejection device available, with which the movement rail 5 and thus the drawer from the closed position or a to offset only a few millimeters in direction P2 release position according to figure 2 is movable relative to the body rail 3 under the action of a charged ejection energy store in the opening direction P1. The ejection takes place over a first section of a total possible displacement distance of the drawer rail 5.

In the closed position according to figure 1 the drawer rail 5 remains in the closed position under the action of the spiral spring 8, which is stronger than the ejection force accumulator. Only when an external action on the drawer by z. B. pressing a front of the drawer in the closing direction P2, the drawer rail 5 in the release position according to figure 2 brought, so that as a result the effect of the spiral spring 8 on the drawer rail 5 is canceled and the charged ejection force accumulator the drawer rail 5 according to figure 3 ejects in the opening direction P1.

figure 4 relates to the operating state of the freely movable drawer rail 5 or drawer. According to figure 5 the coil spring 8, which was partially discharged during the previous retraction, is tensioned by manually opening the drawer further or by moving the drawer rail 5 in the opening direction P1, ie lengthened here, which is explained further below. At the end of the loading process of the spiral spring 8 according to figure 6 the movable point of application of the spiral spring 8 is deflected or pivoted on a latch part 9 in such a way that the tensioned spiral spring 8 remains in this tensioned situation by holding the latch part 9 .

The interplay between the movement of the drawer and the furniture component device 1, which is set up for different operating situations, is implemented via the drawer rail 5 via actuating means present thereon. For this are on A bracket-shaped first driver 10 with two ends 10a and 10b and a second driver 11 are firmly fixed to a vertically extending section 5a of the drawer rail 5 and each temporarily interact with the latch part 9 .

In the closed position according to figure 1 the end 10b is caught on the pawl part 9, whereby the coil spring 8 exerts a tensile force on the pawl part 9, thereby pulling an edge 9a of the pawl part 9 against a stopper 12 formed on a stopper part 23.

By means of a release stroke of the closed drawer or the drawer rail 5 when pressed in the closing direction P2 according to FIG figure 2 the end 10a pushes the pawl part 9 in direction P3 into a deflection link 13, whereby the driver 10 and the pawl part 9 are decoupled, so that the spiral spring 8 on the drawer rail 5 subsequently becomes ineffective. The deflection link 13 is formed on a link element 18 assigned to the body rail 3 with incisions 14 and 15 , with the latch part 9 having two downwardly protruding lugs 16 and 17 which are matched to the incisions 14 and 15 .

The charged ejection force accumulator can now become effective on the drawer rail 5, which is released from the force of the spiral spring 8, so that the drawer rail 5 is moved in direction P1, whereby after a short distance the end 10b releases the latch part 9 in the opposite direction to P3 from the evasive link 13 resets. The drawer rail 5 can then move freely in the opening direction P1 until the second driver 11 and the latch part 9 engage ( figure 5 ) and by manually opening the drawer or the. Drawer rail 5 entrains the latch part 9 in the direction of P1 and stretches it or loads it. When the spiral spring 8 is fully tensioned, the pawl part 9 pivots slightly Page into a hold position as per figure 6 , so that the driver 11 is released from the latch part 9. The drawer rail 5 can then be freely displaced in direction P1 up to a maximum open position.

When the drawer rail 5 is then moved back in the closing direction P2, the driver 10 comes into contact with the pawl part 9, with the result that this pivots back out of the holding position and, by means of the retraction arrangement 7, the pawl part 9 is carried along by the driver 10 in the direction P2 under the action of the charged spiral spring 8 and the drawer rail 5 retracts in the closing direction P2 until the closed position is reached when the catch part 9 hits the stop 12 .

Furthermore, on a vertical section 5b of the drawer rail 5 opposite section 5a, a contact element designed as a pin 19 protrudes on the drawer rail 5, which is used to operate a synchronization device attached to the cabinet rail 3 for synchronizing the pressing-in movement of the drawer rail 5 with a corresponding movement of another Drawer rail of a second guide 2 corresponding guide is used on the furniture part in question. The pin 19 is in the closed position of the furniture part according to figure 1 or according to figure 9 on a prestressed, deflectable swivel bracket 20 of the synchronization device. The pivot bracket 20 can be pivoted about a horizontal axis S transversely to the displacement direction of the drawer rail 5 to a limited extent according to P4. In the biased basic position of the swivel bracket 20 according to figure 1 or. figure 9 comes the pin 19 in a trough between two prongs 20a and 20b of the swivel bracket 20 which widen outwards.

In the basic position of the swivel bracket 20, the z. B. can be pivoted by about 60 degrees against the force of a swivel bracket spring in the direction of P4, the pin 19 on the Move the drawer rail 5 in or out between the prongs 20a and 20b. In the closed position of the furniture part, the pin 19 rests against the rear prong 20b, with the pin 19 pressing the rear prong 20b backwards when the drawer rail 5 is pressed in the closing direction P2, so that the swivel bracket 20 together with a pin 21 on it rotates about the axis S is pivoted in the direction of P4, whereby a further pivoting bracket corresponding to the pivoting bracket 20 is pivoted accordingly on the other guide on the furniture part and the drawer rail there is thus displaced synchronously in the direction of P2. For this purpose, there is an extension (not shown) on the pin 21, which correspondingly engages on a pin of the further swivel bracket.

As a result, the pawl part on the other guide is also pressed laterally into a deflection link, which means that both guides are synchronously free for the effect of the respective ejection force accumulator on the associated drawer rail.

In the prestressed basic position of the swivel bracket 20, the pin 19 can move between the prongs 20a, 20b in the closing direction P2 or can be released from them in the opening direction P1, since the pin 19 can then be moved past the front end of the prong 20a. For this purpose, the two prongs 20a, 20b are designed in such a way that in the prestressed basic position of the pivot bracket 20 the free end of the front prong 20a is horizontally somewhat lower than the free end of the rear prong 20b.

Starting from the closed position according to figure 1 causes the pin 19, when pressing the drawer rail 5 in direction P2 ( figure 2 ), by pressing on the inside of the rear prong 20b, pivoting of the pivot bracket 20 and thus rotation according to P4 of the pin 21 connected to the pivot bracket 20 about the axis S.

When setting the exact closed position of the drawer, for example for a uniform front image of the piece of furniture with the front sides of all front sections of the piece of furniture aligned with one another, the drawer rail 5 is adjusted by adjusting the stop 12 in direction P1 or P2 in the millimeter range and the pin 19 In order to ensure that when the drawer rail is adjusted, the pin 19 and a synchronization part 24 with the swivel bracket 20 present on it do not move figure 9 take another relative position to each other, which can result in a failure of the synchronization effect, with the adjustment of the drawer rail 5 or the stop 12, a particularly similar adjustment of the swivel bracket 20 is set up according to the invention. This is done using a unit 22 according to figure 9 realized. The unit 22 is advantageously built very flat from sheet metal parts, comprising the link element 18 with the deflection link 13, the stop part 23 with a component edge forming the stop 12 and the synchronization part 24 with the swivel bracket 20 described above. B. detachably plugged together by hand.

In the illustrated exemplary embodiment according to the invention, the stop 12 and the synchronization part 24 are moved forwards or backwards in an identical manner or in the same dimension and direction, here linearly, in accordance with the double arrow P5 ( figure 7 ).

The joint adjustment of the unit 22 set up for this purpose relative to a horizontal section 3a of the carcass rail 3 is advantageously carried out steplessly, for example with a maximum adjustment path forwards or backwards by a few millimeters. The unit 22 is attached to the section 3a in the area of a receiving contour 26 matched to the unit 22 and present in section 3a, with an opening 27 and further recesses present in section 3a for the link-like sliding guidance of the unit 22.

With the adjustment of the unit 22, the stop 12 and the synchronization part 24 are adjusted identically in direction and amount according to the invention in an advantageous manner. The guide 2 installed on the furniture is adjusted via a worm wheel 25 that is accessible from above on section 3a and can be rotated in both directions of rotation about the axis of rotation D. The axis of rotation D, which is vertical in the assembled state, is fixed in position relative to the cabinet rail 3 or section 3a. The worm wheel 25 has, for example, an engagement contour for engaging a turning tool on the upper side.

A worm thread is formed on the underside of the worm wheel 25, which interacts with three slightly curved adjusting ribs 28 projecting upwards on the stop part 23, with the unit 22 being adjustable in direction P1 or P2 depending on the direction of rotation by turning the worm wheel 25.
