The invention relates to a pull-out for extending a movable furniture part of a furniture body, comprising a carcass rail for attachment to the furniture body, a relative to the carcass rail displaceably guided center rail, on the one above the other a differential role, which has a game in the vertical direction and on a track of the Carcass rail unrolls, and a support roller are rotatably mounted, and a relative to the carcass rail guided Ausziehschiene for attachment to the pull-out furniture part, which has a catwalk, which runs when pulling the puller to a first Ausziehposition through the gap between the differential role and the support roller and which, upon further extension of the pull-out rail, extends out of the gap between the differential roller and the support roller.
Differential pull-out guides, in which a synchronous running or differential running of the middle rail when pulling out the pull-out rail is achieved, for example, from AT 391603 B, AT 505053 B1 and EP 2074909 A1. In a central region of the center rail, a differential roller is rotatably mounted, which runs on a track of a catwalk of the pull-out rail and a track of a guide web of the carcass rail. The differential role is in this case load-transmitting, that is, a portion of the weight of the pull-out rail and the parts carried by it is derived via the differential role on the carcass rail. Above the differential roller is a support roller. This serves to support the catwalk of the pull-out against pivoting upwards, especially in the extended state of the pull-out rail. The catwalk of the pull-out rail thus runs when pulling out the pull-out through a gap between the differential roller and the support roller. In order to reliably hold the differential roller with both the track of the carcass rail and with the runway of the catwalk of the pull-out, the differential role is usually stored with a present at least in the vertical direction game against the center rail.

In the case of the differential pull-out guide resulting from the AT 505053 Bl, this is equipped with a retractable automatic mechanism (= self-closing mechanism) in order to retract the pull-out rail automatically during insertion over the last section of its path.
In order to provide an over-extension in which the pull-out of the pull-out rail is greater than the length of the carcass rail, an additional support roller is rotatably mounted on the center rail in the area in front of the support roller (= further lying at the pull-out end of the center rail as the support roller). When the catwalk of the pull-out rail extends out of the gap between the differential roller and the support roller, which is required to reach the over-extension, the additional support roller supports the catwalk of the pull-out against pivoting upwards. Below the additional supporting role usually an auxiliary support member is arranged, which is usually designed as a sliding member to support the catwalk of the pull-out rail against pivoting down in the case of a very far back weight distribution of the extendable furniture part. Such differential pull-outs with over extension are known.
In addition to roller pull-out guides, in which all the rollers enabling the mutual displacement of the rails are rotatably mounted about (at least substantially) axes which are stationary relative to the rails, pullout guides are also known, which have carriages fitted with balls or rollers.
In the role differential extension guides usually all rollers are rotatably mounted on the center rail.
In the role-pull guides are known as another type telescopic extension guides in which on all rails load-transmitting rollers are rotatably mounted and in which the pull-out and the center rail are pulled out of the carcass rail successively. It comes at the end of Ausziehweges the pull-out of the middle rail to a start of a stop element of the pull-out on a stop element of the center rail and an associated shock, whereby the running culture is impaired. Excerpts have therefore already been developed according to the telescopic design, in which additional measures are provided to achieve a simultaneous extension of the rails, as is the case with separations of the differential type. For example, this can be provided on the middle rail a window recess of the middle rail passing through elastic Mitnehmerrolle running on tracks of the pull-out rail and the carcass rail, but no load-carrying role «···· * * * 4 t ··· * ·· ** l «T * • | »·« * I Φ 4 4 «* ·» m 9 ¥ 4 4 I 1 represents. Such a telescopic extension with differential effect, for example, from AT 392883 B shows.
Although the described Differentialausziehführungen have proven effective with over extension, it comes with these pull-out by the extension of the catwalk from the gap between the differential role and the support roller to a deterioration of the running culture. It comes here when pulling out to a certain lowering of the pull-out and when retracting to appropriate increase. The extension of the catwalk of the pull-out rail from the gap between the differential roller and the support roller when pulling out and threading into this gap when retracting is hereby noticeable and possibly also audible. Also occurs at the moment of retraction of the catwalk of the pull-out in this gap to a force acting on the center rail in the longitudinal direction of the center rail force, whereby the synchronous operation of the center rail can be impaired.
The object of the invention is to provide a pull-out guide of the type mentioned with an improved running culture. According to the invention, this is achieved by a pull-out guide with the features of claim 1.
In the pull-out guide according to the invention, a tongue is displaceably mounted on the middle rail between a passive end position and an active end position. For this tongue, a displacement device is provided which, when the pull-out guide is pulled out, displaces the tongue from its passive end position, in which the tongue lies outside the gap between the differential roller and the support roller, into the active end position, in which the tongue is inserted into this gap is. The insertion of the tongue in the present between the differential role and the support roller gap here is at the latest when the catwalk is extended from this gap. As long as the runway of the pull-out rail passes through the gap between the differential roller and the support roller, the center rail is displaced synchronously or differentially to the pull-out rail (at half the speed or half the distances with which the pull-out rail is displaced). If the catwalk of the pull-out rail extends out of the gap between the differential roller and the support roller, there is no further displacement of the center rail. Preferably, when pulling the pull-out rail before the catwalk of the pull-out rail extends out of the gap between the differential roller and the support roller, the tongue is inserted into this gap, wherein in the overlapping area, in which both the catwalk and the tongue in the gap. 4
The walkway and the tongue each extend over part of the width of the gap.
By retracting the tongue in the present between the differential roller and the support roller gap when the catwalk of the pull-out is extended from this gap, a reduction in the width of this gap due to the vertical clearance of the differential role is at least largely prevented. This improves the running properties. The transition between the state in which the catwalk runs between the differential roller and the support roller, and the state of the catwalk pulled out of the gap between the differential roller and the support roller is ideally no longer, but at least less noticeable. The synchronous movement of the center rail is thus more reliable when inserting the pull-out. The lowering of the pull-out rail and the extendable furniture part carried by it in the last section of the extraction is at least reduced.
The displacement device is driven by the mutual movement of the rails when pulling out the pull-out guide. In an advantageous embodiment of the invention, the displacement device is driven by the movement of the center rail relative to the carcass rail when pulling out the pull-out guide. Preferably, in this case, a drive part of the displacement device is slidably disposed on the middle rail, which has a stop which extends when pulling the pull-out rail before reaching the pull-out of the pull-out, in which the catwalk of the pull-out rail from the gap between the differential roller and the support roller, to a counter-stop the carcass rail starts and keeps the drive part stationary with respect to the carcass rail on further extension of the pull-out rail. Thus, as long as the center rail moves (until reaching the pull-out position where the catwalk of the pull-out rail extends out of the gap between the differential roller and the support roller), the drive member is displaced from the center rail, thereby driving the shuttle. This moves the tongue from its passive end position to its active end position. Conceivable and possible would be the arrangement of the counter-attack on the pull-out, but the movement of the drive member is longer, since the pull-out moves to the end of Ausziehweges (a decoupling of the tongue from the movement of the drive member at a desired position of the pull-out Extending rail can be provided). If this is not desired, after a certain displacement distance of the drive part and a decoupling from 5
Counter-attack done, for example, in the way, as is known from tilting slides of automatic feed (= Selbsteinzügen) ago.
In other possible embodiments, the driving part could also be arranged on the pull-out rail or on the carcass rail, cooperating with a part of the displacing device arranged on the center rail when it is moved past it when the pull-out device is pulled out in order to move the tongue away from the latter by means of the displacing device to move passive people to their active end position. For example, the drive part could be a toothed rack, from which a toothed wheel of the displacement device arranged on the center rail is driven.
A preferred embodiment of the invention provides that the displacement device has a drive gear which meshes with a toothing of the tongue or a part connected thereto, wherein the rotation of the drive gear, the tongue is moved from its passive to its active end position. With the drive gear or with a gear, which drives the drive gear directly or via at least one further gear member, such as another gear or a belt, meshes a toothing of the drive member. By the displacement of the drive member relative to the drive gear or the other gear, with which it meshes, thereby the tongue can be moved from its passive to its active end position.
The tongue is advantageously guided in the region of its insertable in the present between the differential roller and the support roller gap end of a slotted guide relative to the center rail. This slotted guide comprises a Kuiissenöffnung arranged advantageously in the middle rail and an advantageously arranged on the tongue pin, which engages in the gate opening. Through this slotted guide can roll in the gap between the differential and the support roller insertable end of the tongue in the displacement of the tongue of their passive in their active end position both in the longitudinal direction of the center rail (= in the withdrawal direction) and in height. In this way, the tongue can release in its passive end position and the displacement of the catwalk of the pull-out.
In order to shift the tongue when inserting the pull-back guide from its active end position into its passive end position, it is preferably provided that the catwalk of the pull-out rail enters the gap present between the differential roller and the support roller and in this case approaches the tongue on the front side. This frontal approach to the tongue thus takes place from the first extended position of the pull-out rail, the further insertion of the pull-out rail pushes the tongue out of the gap and into its passive end position.
Instead, it would also be conceivable and possible that a stop of the pull-out rail starts against a counter-stop connected to the tongue and thereby shifts the tongue from its active end position into its passive end position when the pull-out rail is inserted. Also, this could be a stop of the displaceably mounted relative to the center rail drive part with a counter-stop of the pull-out rail or the carcass rail interaction. If the drive part is arranged on the pull-out rail or on the carcass rail (for example formed by a toothed rack arranged on the pull-out rail or on the carcass rail), the displacement of the tongue from its active end to its passive end position could also be effected by the displacement of the drive part with respect to the middle rail become. Conveniently, an additional support roller is rotatably mounted on the middle rail in the region of the longitudinal extension of the middle rail, which is located between the support roller and the front end of the center rail. This acts when the catwalk of the pull-out rail is extended out of the gap between the differential roller and the support roller, with the track at the top of the catwalk of the pull-out together.
Preferably, the pull-out guide of the present invention is formed in a form of a roll pull-out guide, i. all rollers for mutually displaceable guidance of the rails are rotatably mounted on at least one of the rails. It is particularly preferred that all provided for mutually displaceable guidance of the rails rollers are rotatably mounted on the center rail. Conveniently, the support roller is rotatably mounted above the differential roller in a central region of the center rail.
Advantageously, at the middle rail in the region of its front end, a front roller, which cooperates with a track on the underside of the catwalk of the pull-out, and rotatably mounted in the region of its rear end, a rear roller having a track on the underside of a guide web of the carcass rail interacts, as is well known and customary.

An embodiment of a pull-out according to the invention is shown in Figs. 1 to 23 The pull-out used to pull out a pull-furniture piece, in particular a drawer, from a furniture body (not shown in the figures), wherein on both sides of the pull-out furniture part mirror-trained pull-out the type shown are attached. The pull-out guide comprises a body rail 1 to be fastened to the furniture body, a pull-out rail 3 to be fastened to the pull-out furniture part, and a middle rail 2 lying therebetween.
The carcass rail 1 has a vertical base web 4, with which it rests in the fastened state on the furniture body, and connected to the base web 4 at its upper and lower edge upper and lower horizontal guide webs 5, 6. These can be connected to the base web 4, for example via bends be, as shown in the Ausführungsbeispie! for the upper guide bar 5 is the case. Preferably, the guide webs 5, 6 are provided at their free edges with towards each other Umbördelungen 7, 8.
The pull-out rail 3 has a vertical base bar 9, a horizontal walkway 10 connected to the upper edge of the base bar 9, and a side bar 11 extending downwardly from the catwalk 10 at its edge remote from the vertical base bar 9 of the pull-out bar 3. The side bar 11 is shorter than the vertical base web 9 and thus extends less far down. The catwalk 10 may be connected to the base web 9 as shown via a bend,
Instead, for example, from the lower edge of the vertical base web and a lower horizontal web could go out (in the opposite direction as the catwalk 10) on which rests the extendable Möbeiteil.
The pull-out guide is designed as a roller pull-out guide and the rollers for mutually displaceable guidance of the rails 1, 2, 3 are rotatably mounted on the middle rail 2. Here are at the middle rail 2 in the region of its front end 12, a front roller 14, in the region of its rear end 13, a rear roller 15 and in its central region a differential roller 17 and a roller 13 lying above the differential roller 17 rotatably mounted. The differential roller 17 and the support roller 16 include a gap s with each other (see Fig. 16).
The front roller 14 cooperates with a track at the bottom of the catwalk 10 of the pull-3 and supports the pull-3 in the extended state of the rails against tipping down from.
The rear roller 15 cooperates with a track at the bottom of the upper guide bar 5 of the carcass rail 1 and supports the rear end 13 of the center rail 2 in the extended state of the pull-out against pivoting upwards.
The support roller 16 cooperates with a track at the top of the catwalk 10 of the pull-3 and can form a counter bearing for the pull-3 in the partially extended state of the rails (before the catwalk 10 from the gap between the differential roller 17 and the support roller 16) (against a pivoting of the pull-out rail up).
The differential roller 17 cooperates both with an upward trajectory on the upper side of the lower guide web 6 of the body rail 1 and with the downward career on the underside of the catwalk 10 of the pull-out 3 together (before the catwalk of the pull-out of the gap between the Differential roller 17 and the support roller 16 extends) and causes the differential or synchronous running of the center rail 2, when the pull-3 is pulled out. The middle rail is in this case when pulling the pull-out rail 3 in the pull-out direction 35 (wherein the middle rail 2 with its longitudinal extent is parallel to the withdrawal direction 35) and moves when inserting the pull-out against the pull-35 each half way, the pull-3 back from the Differential role 17, a load from the pull-3 is transmitted directly to the carcass rail 1. The differential roller 17 is mounted with Spiet with respect to its axis of rotation, as is known and customary. This results in a game (= a displacement) of the differential roller 17 (also) in the vertical direction. In this way, tolerances can be recorded and a sufficient pressure force of the differential roller 17 on the raceways of the catwalk 10 and the guide bar 6 is achieved. An achsiose storage of the differential roller 17 on the middle rail 2 with game or a storage on an axis that has a game in the vertical direction relative to the center rail 2 is conceivable and possible.
Preferably, on the center rail 2, an auxiliary roller 18 is supported with play relative to its axis of rotation, in a lying between the differential roller 17 and the rear end 13 of the middle rail 2 region of the longitudinal extent of the center rail 2. This auxiliary roller 18 can be connected to the track on the Bottom of the catwalk 10 of the pull-3 and the track at the top of the lower guide bar 6 of the carcass rail 1 interacts and serves to support against tipping down the rear end 19 of the pull-3 in the retracted or slightly extended state of the pull-out. In principle, a slider could also be provided instead of the auxiliary roller 18. In principle, other auxiliary rollers 18 or slider could be provided. For example, two smaller auxiliary rollers could be provided, one of which cooperates with the downwardly oriented track of the catwalk 10 and the other with the upwardly directed track of the lower guide web 6. In principle, it would also be conceivable, instead of the illustrated auxiliary roller 18, to rotatably support at least one auxiliary roller in the area between the middle roller 16 and the front roller 14 on the middle rail 2, which coincides with the track at the top of the catwalk 10 Extending rail 3 cooperates.
To enable an over extension, an additional support roller 19 is rotatably mounted on the center rail 2, in a lying between the differential roller 17 and the front end 12 of the middle rail portion of the longitudinal extension of the center rail 2. The additional support 19 acts with the track at the top of the Catwalk 10 of the pull-out rail 3 together and forms an abutment for the pull-3 in the region of the over-pull (against a pivoting of the pull-3 upwards).
Further, in the area between the differential roller 17 and the front end 12 of the center rail 2 on the center rail 2, an auxiliary support member 20 is arranged. This can cooperate in the region of the over extension with the track on the underside of the catwalk 10 of the pull-out rail 3 in order to support the rear end of the pull-out rail 3 against pivoting of the pull-out rail 3 downwards (in the case of a load distribution of the pull-out rail 3 carried very far back) extendable furniture part), the auxiliary support member 20 is formed in the embodiment shown as a slider, but could also be designed as a role.
In the exemplary embodiment shown, the middle rail 2 has two offsets, resulting in an upper vertical section 21, a middle vertical section 22 and a lower vertical section 23, of which the upper and lower vertical sections 21, 23 are vertically above one another and the middle one vertical section 22 is laterally offset. The rear roller 15, the support roller 16 and the auxiliary support roller 19 are rotatably mounted on the upper vertical portion 21. The front roller 14, the differential roller 17, the auxiliary roller 18 and the auxiliary support member 20 are rotatably supported at the lower vertical portion 23.
Stops 24, 25 are adjustable in a conventional manner for the assembly and disassembly of the rails 1-3.
The center rail 2 could also have another known from roller differential extension guides ago training, for example, a training with a continuous vertical base web, projecting from the upper and lower edge horizontal guide webs, as is apparent from the mentioned in the introduction of the prior art.
On the middle rail 2, a spacer unit is mounted in a region of the longitudinal extent of the center rail 2, which is behind the differential roller 17 and support roller 16, which alone in FIGS. 22 and 23 dargestelit.

Tongue 26, which is slidably mounted by a mounted on the middle rail 2 bearing member 27. The tongue 26 is thus slidably mounted in the attached to the middle rail 2 state of the bearing part 27 relative to the central rail 2. The tongue 26 is provided with a toothing 28 over part of its longitudinal extent. At this toothed region includes an untoothed portion 29, which serves for insertion into the gap between the differential roller 17 and the support roller 16, as will be described in more detail below. The section 29 connects to the end 30 of the tongue 26, which in the mounted state of the spacer unit front (relative to the pull-35) lies. The toothing 28 of the tongue 26 meshes with a drive gear 31, which is rotatably mounted on the bearing part 27. The drive gear 31 meshes further with a toothing 33 of a drive member 32. The drive member 32 is slidably supported by the bearing member 27, so that the drive member 32 is mounted in the middle rail 2 mounted state of the bearing member 27 relative to the center rail 2 in the longitudinal direction. The drive part 32 has a stop 34 in the region of its rear end.
The tongue 26 is flexible and guided in the region of its front end 30 by a slotted guide relative to the center rail 2. This slide guide comprises a sliding recess in the middle vertical section 22 of the middle rail 2 and a pin 37 which is mounted in the region of the front end 30 on the tongue 26 and projects into the sliding recess 36. In the displacement of the tongue 26 relative to the bearing member 27, the front end 30 of the tongue is thereby displaced both in the longitudinal direction of the center rail 2 and in the height. The guided by the bearing part 27 portion of the tongue 26 is guided in a direction parallel to the longitudinal extent of the center rail 2 (or parallel to the withdrawal direction 35).
When the pull-out rail 3 is pulled out starting from its completely retracted state (corresponding to FIGS. 1 and 2), the middle rail 2 initially shifts differentially to it. The tongue 26 is initially in a passive end position. When the pull-out position shown in FIGS. 3 to 6 is reached, the stop 34 of the drive part 32 abuts against a counter-stop 38 of the carcass rail 1. Upon further extension of the pull-out rail 3, the middle rail 2 initially also moves further in the pull-out direction 35. The drive part 32 is held stationary relative to the carcass rail 1 and thus shifts relative to the bearing part 27 and the middle rail 2. Thus, the drive gear 31 rotated from the bearing part 27 and the drive gear 31 moves the tongue 26 relative to the center rail 2, wherein the end 30 of the tongue 26 moves toward the front end 12 of the center rail 2 and according to the slotted guide down. The end 30 of the tongue 26 is guided in this case to the gap between the support roller 16 and the differential roller 17.
In this first portion of the extraction of the puller the catwalk 10 of the pull-out rail 3 passes through the gap between the differential roller 17 and the support roller 16. In the pull-out position of the pull-out rail 3 shown in FIGS. 7 to 11, the catwalk 10 of the pull-out rail 3 moves out of it Gap out, ie the careers at the
Top and bottom of the catwalk 10 get out of engagement with the support roller 16 and the differential roller 17. At least in this pull-out position, the tongue 26 is retracted into the gap between the support roller 16 and the differential roller 17.
It is preferred if the end 30 of the tongue 26 is already slightly in front of the pull-out position of the pull-out rail 3 shown in FIGS. 7 to 11, in which the catwalk 10 is disengaged from the support roller 16 and the differential roller 17 the support roller 16 and the differential roller 17 is retracted. For this purpose, the catwalk 10 has at its rear end a recess 39 which is at least over a portion of their relation to the longitudinal extent of the pull-3 rail extension narrower than the raceways engaging with the running surfaces of the support roller 16 and the differential roller 17. In this recess 39 moves a subsequent to the end 30 of the tongue portion of the tongue 26 before reaching the pull-out position of the pull-3 shown in Figs. 7 to 11, preferably at least 2mm before reaching this pull-out position.
The recess 39 and the tongue 26 then at its end 30 are wedge-shaped in the embodiment shown, as is preferred.
When the catwalk 10 is extended out of the gap between the differential roller 17 and the support roller 16, the tongue 26 thus assumes its active end position. The extension distance between the start of the stop 34 against the counter-stop 38 and the extension of the catwalk 10 from the gap between the differential roller 17 and the support roller 16 (in the pull-out position shown in FIGS. 7 to 11) is preferably less than 5 cm.
The displaceably mounted drive member 32 with the teeth 33 and the stop 34 and the drive gear 31, which meshes with the toothing 28 of the tongue 26, in this embodiment thus form the displacement device for displacing the tongue 26 from its passive to its active end position.
If the pull-out rail 3 is extended further from the pull-out position shown in FIGS. 7 to 11, there will be no further displacement of the center rail 2 in the pull-out direction 35 since the walkway 10 is out of engagement with the differential roller 17. At this position of the center rail 2, a stop for the middle rail 2 is also conveniently provided, by which the extension of the middle rail 2 is limited at this position.
The pull-out position shown in FIGS. 7 to 11 corresponds in the exemplary embodiment shown to a full extension, in which the pull-out rail 3 is extended essentially around the length of the carcass rail 1. Such a design, in which the differential roller 17 and support roller 16 at the moment of extension of the catwalk 10 from the gap between them have substantially reached the front end of the carcass rail 1, is preferred. 13 • · * »m λ
The pull-out rail 3 can be extended further into the region of the over-extension, the middle rail 2 remaining stationary with respect to the carcass rail 1 until the pull-out position shown in FIGS. 12 to 14 has been reached. Further stripping is limited by appropriate stops.
When the pull-out rail 3 is inserted from its completely extended state (FIGS. 12 to 14), the catwalk 10 moves into the gap between the support rollers 16, 17 in the pull-out position of the pull-out rail 3 shown in FIGS. Here, when it enters this gap, it abuts the tongue 26 in its end region pushed into this gap. Upon further insertion of the pull-out rail 3, the catwalk 10 thus displaces the tongue 26 against the withdrawal direction 35. The end 30 of the tongue is displaced upwardly through the slotted guide 36, 37 until the catwalk 10 and the tongue 26 are disengaged. This is the case in the pull-out position of the pull-out rail 3 shown in FIGS. 3 to 6. By the displacement of the tongue 26 relative to the middle rail 2 and the bearing part 27, the drive gear 31 is rotated and the drive member 32 is displaced towards the front end 12 of the center rail 2, the tongue 26 thus again assumes its passive end position and the drive device is located back to their original state.
By inserting the tongue 26 into the gap between the differential roller 17 and the support roller 16, these two rollers are kept correspondingly spaced when the catwalk 10 extends out of this gap, whereby the running culture is improved as already stated.
A pull-out guide according to the invention can furthermore be equipped with a pull-in automatic system (= self-closing device), which is preferred. Such self-feeds for differential extraction devices are known, for example from the cited in the introduction to the prior art.
Various modifications of the illustrated embodiment are conceivable and possible without departing from the scope of the invention. For example, the toothing 28 could be provided on a part connected to the tongue 26. For example, the tongue 26 could also be displaceably mounted directly by the middle rail 2. 14 »*
