EP3603449B1 - Pull-out guide for a drawer - Google Patents

Description

The invention relates to a pull-out guide for a drawer with a carcass rail to be attached to the furniture carcass and at least one pull-out rail that can be moved relative to the carcass rail, comprising a holding element with a connecting element with which the drawer can be adjustably connected to the pull-out rail, the holding element being connected or is connectable and wherein the connecting element is movably mounted relative to the holding element, wherein an adjusting device for the horizontal movement of the connecting element is arranged on the holding element

From the EP 1 147 725 B1 A generic drawer extension guide has become known to the applicant, the rear end of a drawer being connectable to the drawer extension guide without tools via a bearing part mounted on the extension rail in the form of a retaining lug. The retaining lug is mounted on the inside end of the pull-out rail and runs essentially parallel to the top of the same. The rear end of the drawer is assembled and disassembled relative to the pull-out rail by sliding the drawer onto or from the retaining lug. After assembly has been completed by sliding it onto the retaining lug, the rear end area of the drawer is secured against being lifted off and shifted to the side. In order to allow the inclination of the front panel of an already assembled drawer without any significant change in its height relative to the body, the EP 1 147 725 B1 proposed to train the retaining lug adjustable in the height direction.

The AT 9 114 U1 shows a touch-latch pull-out guide in which an actuating element with an eccentric adjusting wheel is used to adjust the depth of the drawer in the furniture body along the longitudinal direction of the pull-out rail. Adjustment in the lateral direction is not shown. Due to the temporary connection of the pull-out guide to the locking unit operated by the touch-latch mechanism, a differently designed or differently placed actuating element is not possible.

Further adjustment options for drawers with regard to pull-out rails in the lateral direction are in the DE 21 23 397 A1 , DE 31 38 204 A1 and the DE 24 22 408 A1 shown, whereby such an adjustment is ensured by wedge surfaces between the drawer and the pull-out guide.

In the DE 20 2006 003 035 U1 and in the DE 20 2007 014 954 U1 describes the measure that an additional lateral displacement of the drawer relative to the pull-out rail can also be brought about. Here, a receiving component is attached to the rear wall of the drawer, which has a slot-shaped opening for receiving a plate connected to the drawer extension guide. The plate can be displaced by a predetermined amount within the slot-shaped opening, as a result of which a lateral displacement of the rear end area of the drawer is also possible. Another possibility for lateral displacement of the drawer relative to the pull-out rail is in the Austrian patent application A 895/2009 shown, in which a retaining pin can be inserted into a pre-drilled hole in the drawer. The holding part mounted on the pull-out rail can be inserted into the holding pin and is displaceable in the lateral direction within the holding pin.

A similar device for adjusting the side of a drawer is in the WO 2007/096156 shown, in which case a retaining pin is slidably mounted in a slot-shaped opening in the retaining part.

Such devices for lateral and height adjustment of the drawer relative to the pull-out rails are necessary to compensate for slight manufacturing tolerances of the drawers or the pull-out guides and to create a homogeneous joint pattern, especially if several drawers are used in a furniture body.

The above-mentioned options for lateral displacement of the drawer relative to the pull-out rail lack the option of a sensitive adjustment device that can be actively operated. In the above devices, a pin is held in a corrugated horizontal recess. By knocking on the drawers or on the holding part, the pin moves in the corrugations and the drawer moves sideways relative to the pull-out rail. A conscious active adjustment of the lateral position of the drawer is not possible because of this the force required to act on the drawer or the holding part in order to get from one recess in the corrugation to the next cannot be applied exactly. The existing devices are therefore insensitive and imprecise to use.

The object of the present invention is to avoid the disadvantages of the above-mentioned prior art and to provide a possibility with which the lateral position of the drawer can be actively adjusted relative to a pull-out rail, with the desired extent of lateral adjustment as possible can be adhered to exactly.

This is achieved by a pull-out guide with the features of claim 1.

The pull-out guide according to the invention thus comprises a holding element with a connecting element with which the drawer can be adjustably connected to the pull-out rail. The holding element itself is connected or can be connected to a pull-out rail of the pull-out guide. The pull-out rail can also be designed in one piece with an integrally formed holding element. The connecting element is movably mounted relative to the holding element, so that a relative movement between the drawer and the pull-out rail is made possible if the connecting element is connected to the drawer.

According to the invention, an adjusting device for the horizontal movement of the connecting element is arranged on the holding element. As a result of the direct or indirect connection of the connecting element to the drawer, the movement of the connecting element is transmitted to the drawer. The adjustment device comprises an adjustment mechanism with which the extent of the horizontal movement can be adjusted and thus the drawer can be actively and sensitively adjusted relative to the pull-out rail.

The connecting element can be arranged, for example, in the rear wall of the drawer or in the side wall of the drawer, for example in the front side of the same on the inside of the body. The pull-out guide according to the invention enables in particular the assembly and adjustment of a drawer made of a wood material, which can be detached, fastened, preferably mounted and / or dismantled without tools as a common structural unit on the pull-out guide.

The adjusting device can be designed to be self-locking, so that after an active adjustment of the drawer relative to the pull-out rail in the lateral direction, an automatic further displacement is prevented. This self-locking can be based, for example, on a frictional engagement of the components of the adjustment device.

Provision is preferably made for the holding element to be connected to the drawer in the rear area, for example on the drawer rear wall with the drawer. For this purpose, the holding element can be arranged at the rear end of the pull-out guide or the pull-out rail of a pull-out guide.

The adjustment device comprises a rotationally movable transmission device with which a rotational movement component can be transmitted to a translational movement of the connecting element. The rotation of the rotationally movable transmission device takes place about an axis which is arranged essentially parallel to the longitudinal axis of the pull-out rail, that is to say about the longitudinal direction of the pull-out rail. The transmission device can, for example, be designed as an adjusting lever or comprise an adjusting lever. The adjustment device enables the drawer to be continuously presented in a lateral direction relative to the pull-out rail. However, means are also conceivable with which a discrete adjustment can take place.

Further advantageous embodiments of the invention are defined in the dependent claims.

In one embodiment of the invention, the pull-out guide comprises a center rail arranged between the pull-out rail and the body rail and movable relative to these. Such a pull-out guide enables the drawer to be fully extended.

The transmission device can be mounted pivotably or rotatably on the holding part or on a fastening part which is mounted on the drawer. A lateral displacement of the drawer relative to the pull-out rail always implies a translational movement. A transmission device with which a rotary Movement component is convertible into a translational movement component, offers the advantage that leverage can be used, so that a sensitive shift is possible in an active manner. The adjusting device can be designed in such a way that a continuous or a stepwise adjustment of the lateral position of the drawer relative to the pull-out rail is made possible.

In one embodiment, the transmission device is designed with a handle for tool-free actuation of the adjustment device. The lateral position of the drawer relative to the pull-out rail can thus be adjusted in a simple manner.

However, it can additionally or alternatively also be provided for the transmission device to be provided with a screw, the transmission device being actuatable by rotating the screw.

In order to facilitate the adjustment, it can also be provided that the transmission device is at least partially lever-shaped or eccentric, so that only small manual forces are required to move even heavy and large drawers.

The transmission device can also comprise an adjusting wheel that has a toothing, or an additional toothed wheel which is in engagement with a horizontally arranged toothing, for example a toothed rack for the lateral displacement of the drawer.

In one embodiment of the invention, the holding element is fixedly connected to the pull-out rail. For this purpose, stop surfaces or support elements can be formed on the holding element, which engage in corresponding recesses in the pull-out rail or are welded to the pull-out rails. However, a detachable connection between the holding element and the pull-out rail is also possible.

It is particularly preferably provided that a guide device is arranged on the holding element, by which the connecting element is displaceably guided on the holding element.

This guide device can have a guide rail mounted in the holding element, with a guide sleeve of the guide groove that at least partially encompasses the guide rail and is mounted displaceably along the guide rail on the connecting element or on the transmission device. In principle, the profile shape of the guide rail is arbitrary. In a simple manner, the guide rail is designed as a guide pin. Such a guide ensures correct and stable displacement in the lateral direction.

The guide device can also have an elongated hole arranged in the holding element or a link guide arranged in the holding element, in which a guide pin or a guide pin of the connecting element engages, the guide pin or the guide pin being slidably mounted in the elongated hole or in the gate.

The holding element can furthermore have a fastening part to be fastened to the drawer. In this case, the above-mentioned guide rail and the above-mentioned elongated hole or the link guide can also be arranged in this fastening part. The fastening part can be designed in the form of a mounting plate.

In a further embodiment of the invention, the connecting element comprises a hook-shaped retaining lug which, in the assembled state in which the retaining element is connected to the drawer, engages in recesses in the drawer. The recesses can be pre-drilled holes. In the assembled state, the retaining lug can be held within the recesses with a press fit or with a sliding fit. The retaining lug can be cylindrical or also have additional latching elements for a more stable connection.

In a further embodiment of the invention, the displacement element comprises a mounting plate which can be fastened to the drawer and on which the adjustment device is mounted. If the adjustment device comprises a rotationally movable transmission device, it can be provided that this transmission device can be rotated or pivoted on the mounting plate is stored. In addition, guide devices for guiding the movement of the displacement element can be arranged in this mounting plate.

In one embodiment of the invention, the pull-out guide can comprise a locking device, by means of which the adjusting device can be releasably locked, so that further lateral displacement of the drawer relative to the pull-out rail is prevented.

According to the invention, a further adjusting device is arranged on the holding element, with which the drawer can be displaced in the vertical direction relative to the pull-out rail. It is provided that the further adjusting device can be actuated independently of the adjusting device for the lateral displacement of the drawer. The side adjustment and the height adjustment are thus decoupled, which means that the greatest possible variety of settings is possible.

With such a further adjusting device, both a height shift and an independent lateral shift of the drawer relative to the pull-out rail is thus possible.

For this purpose it is provided according to the invention that at least one support bracket is arranged on the holding element, on which the drawer or the drawer base rests at least partially in the assembled state. The at least one support bracket can be moved vertically by the further adjustment device relative to the pull-out rail. The at least one support bracket can be part of the connecting element, so that the connecting element can also be moved in the vertical direction, the vertical movement being able to be carried out independently of the horizontal movement on the holding element. The at least one support bracket can, however, also be arranged on a holding part, the holding part being mounted on the holding element so as to be vertically movable. In this case, actuation of the further adjustment device causes the holding part to move vertically. The holding part and the connecting element with which the drawer can be moved in the lateral direction can be moved independently of one another by actuating the further adjusting device or the adjusting device.

The further adjusting device can in principle be constructed similarly to the adjusting device, so that the advantages listed above can also result for the further adjusting device. A position adjustment of the drawer in both the vertical and the lateral direction is thus active and possible with a high degree of accuracy.

According to the invention it is provided that the further adjustment device comprises a rotatably movable further transmission device with which a rotational movement component can be transmitted to a translational movement of the connecting element or the holding part and thus of the at least one support bracket. A drawer resting on the support bracket can thereby be moved vertically.

The invention further comprises a pull-out guide set for a drawer with two pull-out guides to be arranged on opposite sides of a drawer. The pull-out guide set comprises a pull-out guide as described above, which is to be arranged on a first side of the drawer. A second pull-out guide to be arranged on the opposite side of the drawer comprises a second holding element with a second connecting element. The second holding element is connected or can be connected to the second pull-out rail. The drawer can be connected to the pull-out rail of the second pull-out guide using the second connecting element.

According to the invention it is provided that the second connecting element are mounted so as to be movable relative to one another in order to adapt to the relative position displacement of the holding element and the connecting element of the first pull-out guide when the drawer is mounted. The second connecting element is floatingly mounted on the second holding element and can follow the relative displacement of the connecting element on the holding element of the first pull-out guide of the pull-out guide if a drawer is connected to the connecting element and the second connecting element is connected to the pull-out rails of the first and second pull-out guides. The floating mounting is preferably limited to the horizontal movement of the second connecting element, ie the second connecting element is floatingly mounted in the horizontal direction, while a fixation of the second connecting element can be provided in the vertical direction. However, a floating mounting both in the horizontal and in the vertical direction is also conceivable.

As a result of this measure, only one holding element has to have an adjusting device as described above, which means that costs can be saved.

It is particularly preferably provided that a second guide device is arranged on the second holding element, by which the second connecting element is displaceably guided for displacement on the second holding element.

In a further embodiment, the second holding element comprises a locking device, by means of which the second displacement element can be releasably locked. It can be provided that a locking device is only arranged on the second holding element, which also blocks the horizontal movement of the connecting element on the holding element of the first pull-out guide and therefore prevents the drawer from shifting sideways relative to the pull-out rail.

As stated above, the floating mounting of the second connecting element on the second holding element, which enables a movement of the second connecting element following the displacement of the connecting element on the holding element, can be limited to the horizontal movability. In this case in particular, a further embodiment of the invention provides that a further adjustment device for vertical displacement of the drawer is arranged on the second holding element. This further adjustment device can be designed in the same way as the further adjustment device on the holding element of the first pull-out guide. If the floating mounting relates only to the horizontal direction, the vertical position of the second connecting element on the second holding element is not floating but slidably mounted, the further adjustment device being provided for the displacement. Both for the further adjustment device on the second holding element and for the further adjustment device on the holding element it can be provided that these are designed to be self-locking so that the set position cannot be adjusted automatically. By means of a further adjustment device also on the second holding element, both side walls of the mounted drawer can be vertically adjusted to the same extent.

The invention further relates to a pull-out guide set for a drawer, comprising a first pull-out guide with a first fastening element and a second pull-out guide with a second fastening element. The first pull-out guide can be connected to the drawer with the first fastening element. The second pull-out guide can be connected to the drawer with the second fastening element. The two pull-out guides are arranged on opposite sides of a furniture body. A first fastening element is movably mounted in or on an adjusting element arranged on the first pull-out guide, this adjusting element serving to move the drawer relative to the first pull-out guide in the lateral direction, i.e. a movement of the adjusting element is transferred to a relative movement of the drawer with respect to the first pull-out guide in the lateral direction and vice versa. The movement of the adjusting element can include a rotary movement or a pivoting movement about a vertical axis. Of course, other forms of movement are also conceivable.

Such an adjusting element allows the drawer to be shifted sideways relative to the first pull-out guide in a simple manner, for example in order to correct the installation position of a drawer installed at a slight angle. However, a one-sided relative displacement can lead to the drawer becoming jammed in the furniture body and a pull-out movement no longer possible at all.

In order to avoid this problem, it is provided according to the invention that a bearing part is arranged on the second pull-out guide, in which the second fastening element is movably mounted relative to the first pull-out guide to adapt to the displacement of the drawer. Thus, the drawer can be moved in the lateral direction not only relative to the first pull-out guide but also to the second pull-out guide. The second fastening element is floatingly mounted in the bearing part so that the drawer can also follow the adjustment movement by means of the adjusting element on the side of the second pull-out guide.

It is preferably provided that the first fastening element is arranged in the front half of the first pull-out guide, in particular the pull-out rail of the first pull-out guide. Additionally or alternatively, it can be provided that the second fastening element is in the front half of the second pull-out guide, in particular to arrange the pull-out rail of the second pull-out guide. The front half of the pull-out guide refers to the area from the front panel of the drawer towards the rear wall of the drawer.

The first and the second pull-out guide each have a body and a pull-out rail. A middle rail with which the drawer can be fully extended can be arranged between the body rail and the pull-out rail. The first and the second fastening element can be arranged on the pull-out rails of the first and second pull-out guide.

In addition to the first and second fastening element with the adjusting element and the bearing part, a holding element and a second holding element can also be provided in the rear area of the drawer, which, as described above, are also designed for lateral displacement of the drawer relative to the pull-out guides or for following this movement are, it is possible to move the entire drawer as parallel as possible, i.e. in the front and rear areas in a lateral direction, which further minimizes any risk of jamming caused by an inclined drawer.

In order to enable the simplest possible type of connection between the drawer and the first and second pull-out guides, one embodiment of the invention provides that the first fastening element and, additionally or alternatively, the second fastening element comprise a pin that is inserted into recesses in the drawer base or in the side walls of the drawer is used. The plug-in pin can have locking elements with which the connection with the drawer is improved.

In a further embodiment it is provided that the first adjusting element comprises a latching device with which the first fastening element engages in a latching manner. This prevents automatic resetting after the drawer has been shifted sideways as a result of the latching engagement. However, the adjusting element can also have a self-locking mechanism based on a frictional connection to prevent an automatic return. Furthermore, a discrete page shift can thereby be made possible.

The invention further relates to a drawer with at least one pull-out guide as described above or a pull-out guide set as described above.

The invention further relates to a piece of furniture with at least one such drawer.

The partially broken perspective view of Fig. 1 shows a piece of furniture 1 with several pull-out drawers 2 arranged in a furniture carcass 4, each of which is mounted in the furniture carcass 4 via two pull-out guides 3, 3 'arranged on opposite sides of the furniture carcass 4. The pull-out guides 3, 3 'are arranged on opposite side walls 2c of the drawer 2. The drawer 2 has a front panel 2a on its front side and a drawer rear wall 2d on its rear side. The drawer bottom 2b is arranged in between.

Fig. 2a shows a plan view of a drawer 2, each with a pull-out guide 3, 3 'on opposite side walls 2c. The pull-out guides 3, 3 'are fastened in the furniture body 4, the furniture body 4 not being shown for reasons of clarity. On a side wall 2c arranged pull-out rail 3a of a first pull-out guide 3, a holding element 5 is arranged at the rear end, which is fastened to the drawer rear wall 2b. At the rear end of the pull-out rail 3d of the opposite pull-out guide 3 ', a second holding element 6 is arranged, which is also attached to the drawer rear wall 2b.

Figure 2b shows the in Fig. 2a Section marked with A in a detailed view. Figure 2c shows the in Fig. 2a Section marked with B in a detailed view. It can be seen that the holding element 5 is connected to the pull-out rail 3a of the pull-out guide and the second holding element 6 is connected to the pull-out rail 3d of the pull-out guide 3 '. The holding elements 5, 6 are also connected to the drawer rear wall 2b.

Figures 3a to 3c shows the arrangement of the Figures 2a to 2c in a front view, the drawer 2 not being shown for reasons of clarity. In Fig. 3a it can be seen that the holding element 5 and the second holding element 6 are each arranged in the lower region of the drawer rear wall 2b. In this picture, the furniture body 4 is shown, with only one pull-out drawer 2 being arranged in the furniture body 4 in the illustrated case.

Figure 3b shows a front view of a second holding element 6 which is arranged on a pull-out rail 3d of a pull-out guide 3 '. The second holding element 6 can for example be welded to the pull-out rail 3d. The pull-out guide 3 ′ also has a carcass rail 3f which is fastened to the furniture carcass 4. A center rail 3e is arranged between the body rail 3f and the pull-out rail 3d, as a result of which the drawer 2 can be fully extended.

Another adjusting device 11, which can be operated without tools via a handle, is used to move the drawer 2 vertically relative to the pull-out guide 3 '. The further adjustment device 11 is pivotably mounted in an elongated hole 12 by means of a bolt 13. A second connecting element 8, which is not shown in this figure for the sake of clarity and by means of which the second holding element 6 is connected to the drawer 2, is mounted floating in the lateral direction on the guide pins and thereby fixed in the vertical direction. In this way, the lateral movements of the connecting element 7 attached to the opposite side can be followed. The second connecting element 8 is constructed essentially like the connecting element 7.

Figure 3c shows the holding element 5 in a front view. The connecting element 7 is displaceably guided by the guide pins 14, ie the connecting element 7 can move relative to the guide pins 14 by means of guide grooves along the guide pins 14 Move holding element 5. The holding element 5 is connected to the drawer 2 via the connecting element 7. This connection cannot be seen in this figure. The position of the connecting element 7 can be actively adjusted in the lateral direction by means of an adjusting wheel 9 of the adjusting device, so that the drawer 2 connected to the connecting element 7 can be displaced in the lateral direction relative to the pull-out rail 3a. Instead of the adjusting wheel 9, which can be actuated without tools, the adjusting device can also be actuated with an adjusting screw 10, which thus also serves to move the connecting element 7 along the guide pins 14. A further adjustment device 11, which is essentially constructed in the same way as in the case of the second holding element 6, is used for vertical displacement of the drawer 2.

While the floating mounting of the second holding element 6 in the horizontal direction means that only one adjustment device is required to move the drawer laterally, in this embodiment further adjustment devices 11 for vertically displacing the drawer 2 are arranged on both sides of the drawer, i.e. on the holding element 5 and on the second holding element 6 .

In the perspective view of the Fig. 4 a further embodiment of a holding element 5 is shown, which is attached to a pull-out rail 3a of a pull-out guide 3 which, in addition to the pull-out rail 3a, comprises a center rail 3b and a body rail 3c. A retaining lug 15 arranged on the connecting element 7 can be inserted into prefabricated bores in the drawer rear wall. By actuating the adjusting lever 18, the connecting element 7 and the retaining lug 15 with the drawer 2 attached to it are displaced along the guide pins 14 in the lateral direction. In the assembled state, the drawer bottom 2b rests on support brackets 16a and 16b which are arranged on a holding part 19 which is movably supported in the holding element 5 in the vertical direction. By actuating the further adjustment device 11, the support brackets 16a, 16b arranged in recesses 20a, 20b of the pull-out rail 3a and the drawer 2 located thereon can be adjusted in the vertical direction relative to the pull-out guide 3. Support elements 17 of the holding element 5 are firmly connected, for example by welding, to the pull-out rail 3a and serve to support, in particular this vertical movement.

Figure 5a shows an exploded view of the holding element 5 of FIG Fig. 4 . The pull-out rail 3a is only shown in sections, however. The support element 17 is connected to the pull-out rail 3a. In the support element 17, a holding part 19 is mounted so as to be displaceable in the vertical direction perpendicular to the longitudinal direction of the pull-out rail 3a. So that this vertical direction of movement is made possible, recesses 20a and 20b are arranged in the pull-out rail 3a, into which the support brackets 16a, 16b can be moved. In an elongated hole 12 and a through hole 21, the further adjusting device 11, which is designed in the form of an adjusting lever, is pivotably mounted by means of a two-part bearing journal 13a, 13b. The latching elements 24 are in engagement with a link 23, so that a pivoting movement of the further adjustment device 11 results in a vertical movement of the holding part 19 relative to the pull-out rail 3a and to the support element 17. The rotational movement of the adjusting lever of the further adjustment device, which is part of a transmission device, is transmitted to the vertical movement of the holding part 19. Since the drawer bottom 2b rests at least partially on the support bracket 16a, 16b when the drawer is in the assembled state, the vertical movement of the holding part 19 is transmitted to the drawer 2.

Guide pins 14 are mounted in the holding part 19. The connecting element 7 is displaceably guided by these guide pins 14 via guide grooves arranged in the connecting element 7 and guide sleeves designed as through holes. The adjusting lever 18 is pivotably mounted in a through hole 22. The connecting element 7 has a retaining lug 15 by means of which the drawer 2 is connected to the connecting element 7 and subsequently via the retaining element 5 to the pull-out rail 3a. A pivoting movement of the adjusting lever 18 is transmitted to lateral stop surfaces on the holding element, so that the connecting element 7 is displaced along the guide rods 14. As a result, the drawer 2 moves in the assembled state relative to the pull-out rail 3a in the lateral direction. The adjusting lever 18 is part of a rotary transmission device, the movement component of which is transmitted to a lateral, translational movement of the drawer.

Figure 5b shows the arrangement of the Figure 5a in assembled condition.

The Figures 6a to 6c show the same arrangement as in Figure 5b . The Figures 6a to 6c differ with regard to the position of the connecting element 7 and the adjusting lever 18 on the holding element 5. As shown in the front view of FIG Figure 7a can be seen, the connecting element 7 and the adjusting lever 18 are in FIG Figure 6a in a position which, viewed from the front, is slightly to the right of the center of the pull-out rail 3a.

If the adjusting lever 18 is pivoted in the direction of the arrow R, the connecting element 7 moves further to the right as seen from the front. This is in the Figures 6b and 7b shown. If the adjusting lever 18 is pivoted in the direction of the arrow S, the connecting element 7 moves to the left when viewed from the front, that is to say in the opposite direction. This is in the Figures 6c and 7c shown.

The ones in the Figures 2a to 2c and 3a to 3c The illustrated embodiment of the holding element 5 is in the perspective view of FIG Figure 8a as well as in the associated exploded view of Figure 8b to see. The only significant change compared to the embodiments of the Figures 4 , 5a and 5b , as well as 6a to 6c and 7a to 7c relates to the adjustment device by which the connecting element 7 in the holding element 5 can be moved horizontally. An adjusting wheel 9 meshes with a gear 25. The adjusting wheel 9 is rotatably mounted in a through hole 22a. The gear 25 is rotatably mounted in the through hole 22 and has recesses, whereby an actuation of the gear 25 with a screwdriver is possible. A bar 26 has latching elements 27 which are in engagement with further recesses, not shown here, on the gear wheel 25. A rotation of the setting wheel 9 is initially transferred to a rotation of the gear 25. Its rotations are transferred to a translational movement of the connecting element 7 along the guide pins 14 by the locking elements 27, which are arranged in the form of the toothing of a rack. The bar 26 is mounted in the holding part 19.

Figure 9a shows in a perspective view the second holding element 6, in the Figures 2a to 2c and 3a to 3c illustrated embodiment. The second holding element is constructed in the same way as the holding element 5, except for the adjusting device for the horizontal movement of the connecting element 7 Figures 8a and 8b . The second connecting element 8 is floatingly mounted on the guide pins 14 and can therefore follow an adjustment of the lateral position of the connecting element 7. A floating storage in one too perpendicular direction is not provided. Another adjustment device 11 for vertical adjustment of the drawer 2 is also arranged in the second holding element 6.

Figure 10a shows in a perspective view the holding element 5 of FIG Figure 8a on a pull-out guide 3, which consists of a pull-out rail 3a, a center rail 3b and a body rail 3c.

The section marked with E in Figure 10a is in a detailed view in Figure 10b shown. The pull-out guide 3 is to be arranged on a first side of a drawer 2. On the opposite side, a second holding element 6 is to be arranged on a second pull-out guide 3 ', which also comprises a pull-out rail 3d, a middle rail 3e and a body rail 3f. This is in Figure 11a shown in a perspective view. The second holding element 6 corresponds to that of Figure 9a .

Figure 11b shows the section of the marked with an F Figure 11a in a detailed view.

Figure 12a shows how the retaining lug 15 of the connecting element 7 engages with the drawer rear wall 2d. The retaining lug 15 is inserted into the drawer rear wall 2d in such a way that the drawer 2 is firmly connected to the retaining element 5. The retaining lug 15 is shown in dashed lines and has appropriate geometric retaining surfaces.

In Figure 12b it can be seen how the retaining lug 15 of the second connecting element 8 engages with the drawer rear wall 2d in the region of the opposite side of the drawer 2.

Figure 13a shows a perspective view of a second embodiment of a holding element 5 and a second holding element 6, which are arranged on pull-out rails 3a or 3d of a pull-out guide 3 or 3 'on opposite sides of a drawer 2 on its drawer rear wall 2d.

Figure 13b shows the section of the marked with G Figure 13a in a detailed view. The support element 17 as well as the further adjusting device 11 and the holding part 19 are designed essentially as in the previous exemplary embodiments, wherein a retaining lug 15 ′ is arranged on the retaining part 19 and is fixedly connected to the retaining part 19.

The connecting element 7 comprises a mounting plate 29 which is mounted on the drawer rear wall 2d. Elongated holes 30 serve for the displaceable guidance of a sliding element 31 which has a recess for receiving the retaining lug 15 '. The holding element 5 is connected to the connecting element 7 via this recess and to the drawer 2 via the mounting plate 29. A lever 32 pivotably mounted on the mounting plate 29, which is part of a rotationally movable transmission device, is in engagement with an elongated hole 33 of the sliding element 31. By pivoting the lever 32, the sliding element 31 is displaced in the elongated holes 30, so that the position of the drawer 2 relative to the pull-out rail 3a shifts in the lateral direction, since the sliding element 31 is connected to the retaining lug 15 'in relation to the lateral direction is fixed.

Instead, it would also be possible to mount the connecting element 7 with the retaining lug 15 'in the same way as in the previous exemplary embodiments on the retaining element 5 so as to be displaceable in the lateral direction, and to mount the sliding element 31 immovably in the elongated holes 30.

If the further adjustment device 11 is actuated, the retaining lug 15 'and thus also the sliding element 31 move in the vertical direction. Since the holes 30 do not allow a relative movement of the sliding element 31 in the vertical direction, the vertical movement is transmitted to the drawer 2.

Figure 13c shows the section of the marked with an H Figure 13a in a detailed view. The further embodiment of the second holding element 6 shown here has essentially the same structure as the holding element 5. Only the lever 32 for adjusting the lateral position of the drawer 2 is missing So that in the event of an actuation of the lever 32 on the holding element 5, the sliding element 31 is displaced in the elongated holes 30 of the holding element 6 if the drawer is connected to both holding elements 5, 6.

As in the case of the holding element 5, it would also be possible to mount the second connecting element 8 with the holding lug 15 'in the same way as in the previous exemplary embodiments on the second holding element 6 so that it can be displaced in the lateral direction, and for this purpose the sliding element 31 in the elongated holes 30 is locked to store.

The Figures 14a to 14d show the holding element 5 in the embodiment of FIG Figure 13b in different views. In the exploded view of the Figure 14e the mounting plate 29, the sliding element 31 and the lever 32 are shown.

In Figures 15a to 15d are different views of the second holding element 6 in the embodiment of FIG Figure 13c shown. The exploded view of the Figure 15e shows the mounting plate 29 and the sliding element 31. The remaining components of the holding element 5 and the second holding element 6, except for the displaceable position of the holding lugs 15, 15 'of the connecting element 7 and the second connecting element 8 on the holding element 5 and on the second Retaining element 6, essentially the same as in the previously described exemplary embodiments, are in the Figures 14a to 14e and 15a to 15e not shown.

Figure 16a shows a view of a first pull-out guide 3 of a further pull-out guide 3 according to the invention with a body rail 3c and a pull-out rail 3a. In the front region of the pull-out rail 3 a, a fastening element 34 is arranged, which can be displaced in the lateral direction relative to the pull-out guide 3 via an actuating element 35 rotatably mounted on the first pull-out guide 3. The adjusting element 35 can also be actuated by a screw 36. Figure 16b shows the in Figure 16a Section marked with I in a detailed view.

Figure 17a shows a front view of the first pull-out guide 3. It can be seen that a holding element 5 with a connecting element 7, which can be moved in the lateral direction on the holding element 5, is arranged on the rear region of the pull-out rail 3a. In the front area of the pull-out rail 3a, a first fastening element which comprises a fastening pin 34 is arranged. This fastening pin 34 is inserted into recesses in the drawer bottom 2b or in a first side wall 2c of a drawer 2. The drawer 2 is thus with the Pull-out rail 3a connected. The fastening pin 34 is connected to the actuating element 35 or movably mounted on it, with a movement of the adjusting element 35 causing a lateral movement of the fastening pin 34 relative to the first pull-out guide 3 and vice versa. The movements of the first fastening element and of the adjusting element 35 are therefore coupled. By connecting the fastening pin 34 to the drawer 2, the lateral position of the drawer 2 can thus be changed relative to the first pull-out guide 3 via the adjusting element 35. The coupling between the first fastening element and adjusting element 35 can be implemented in the form of an eccentric screw, a spiral disk with associated toothing or with articulated levers.

Figure 17b shows the first pull-out guide 3 of Figure 17a , wherein both the first fastening element and the connecting element 7 of the holding element 5 have been displaced laterally in the direction of the arrow T. Because the first fastening element is provided in the front area of the pull-out rail 3a and the connecting element 7 with holding element 5 in the rear area of the pull-out rail 3a, the side wall 2c of the drawer 2 can be moved laterally parallel to the pull-out rail 3a.

Figure 18a shows a view of a pull-out guide set according to the invention with a connected drawer from below. In the rear area of the first and second pull-out guide 3, 3 ', a first and second holding element 5, 6 with first and second connecting elements 7, 8 are arranged. Since these are arranged on the upper side of the pull-out guides 3, 3, 3 ', they cannot be seen in this figure. On the first pull-out guide 3, a first fastening element is connected to an actuating element 35 or is movably supported on it. On the second pull-out guide 3 ′, a second fastening element, which likewise comprises a fastening pin 37, is connected to a bearing part 39 or is movably supported on it. The bearing part 39 is designed in such a way that an active setting of the position of the drawer 2 relative to the second pull-out guide 3 'is not possible. An adjustment of the relative position of the drawer 2 to the first pull-out guide 3 by means of the adjusting element 35 can, however, be followed, so that the drawer 2 cannot be tilted.

Figure 18b shows the one with J in Figure 18a marked section of the second pull-out guide 3 'in a detailed view.

Figure 18c shows the section of the marked with a K Figure 18a the first pull-out guide 3 in a detailed view.

Figure 19a shows a plan view of a second pull-out guide 3 '. In this example, no second holding element 6 is arranged in the rear region of the pull-out rail 3d. A bearing part 39 in the form of a shaft is arranged in the front part of the pull-out rail 3d. An articulated lever 38, which is part of the second fastening element, is rotatably mounted on this shaft. The articulated lever 38 is also mounted, preferably rotatably, on the fastening pin 37, which is inserted into recesses in the drawer 2 provided for this purpose. The mounting of the articulated lever 38 on the bearing part 39 is not self-locking, so that an adjustment of the lateral position of the drawer 2 relative to the first pull-out guide 3 can be followed. In the Figures 19b to d is the section of the marked with an L Figure 19a shown, wherein the position of the articulated lever 38 and thus of the second fastening element 37 relative to the second pull-out guide 3 'differs.

The top of the opposite first pull-out guide 3 can be constructed similarly in this area, ie the first fastening element comprises a fastening pin 34 and an articulated lever 38. However, the mounting of the articulated lever on the pull-out rail 3a is not loose but is self-locking and optionally provided with locking elements so that a lateral adjustment of the drawer 2 relative to the first pull-out guide 3 does not automatically reset by rotating the articulated lever.
