The sliding rail is longitudinally guided on the guide rail and can be placed in the lateral edge region on the bottom face of the extractable furniture part. An adjusting fixture grips the bottom of the furniture part that is to be mounted and in the forward end area of the sliding rail. The adjusting fixture has a mechanism for adjusting the position of a sliding rail relative to the extractable furniture part in the direction of at least one axis of a Cartesian coordinate system formed by three coordinate axes that run substantially perpendicular to each other.

Description

Underfloor guiding arrangement for furniture parts, in particular drawers in the body of furniture

The invention relates to an underfloor guide arrangement for the adjustable mounting of furniture parts, especially drawers, etc., by means of a pair of pull-out guides, each with a fastened to the support wall of the body of the furniture guide rail and one - optionally with the interposition of a middle rail - by rolling longitudinally this guided positioned in the lateral edge region on the underside of the extendable furniture part, the guide rail at least partially embracing from above, as open at the bottom rail rail trained, extendable and are stored in the body of a piece of furniture.

The insertable and extendable mounting of drawers - but also other body parts which can be inserted and pulled out in the body of cabinets, such as worktops, equipment carriers, etc. - takes place today, at least for high-quality pieces of furniture, on the side support walls receiving the drawer in the cabinet body mountable pull-out guides, which each have a fastened to the associated support wall, formed as a metallic rail guide rail and slidably guided by rolling on this guided, also formed as a metallic rail guide rail, wherein in so-called "full extension" between the guide rail and

Running track also a middle rail can be interposed. The lateral edge area of the pull-out furniture parts, d. H. usually the drawers will be on the top of the track, d. H. kept in so-called underfloor arrangement placed below the ground. Even if the components of the cabinet body and the drawer are manufactured exactly, and if the pull-out guides in the cabinet body are mounted correctly, it can not be ruled out that the orientation of the drawers in the cabinet body can not be excluded

Schrankkoφus or adjacent drawers of a drawer cabinet relative to each other during assembly is not exactly successful or subsequently - ^' z. B. by dimensional changes of the wooden components of the furniture itself by dehydration or moisture absorption from the atmosphere - changes. In the case of drawer barriers in particular with a large number of drawers arranged adjacent to one another, such misalignments of the drawers with respect to one another are different gap sizes or over the width of a drawer changing gap visible larger. In the case of not exactly horizontal mounting of the guide rails in the body also recognizable different inclinations of the front panels of drawers can result, which are perceived by the user as aesthetically unsatisfactory. There is therefore a need for the possibility of adjustable mounting of drawers and other extendable furniture parts in the associated body in order to be able to correct any misalignments that have occurred during assembly or even subsequently detected.

The invention has for its object to provide a possibility of correcting misalignments extendable furniture parts in the body of furniture, which quickly and easily - even retrospectively - is feasible without much effort.

Based on a guide arrangement of the type mentioned above, this object is achieved in that at least in the extension in the front end region of the running rail on the underside of the furniture part to be stoppable attacking Verstellbeschlag with a Verstellme- mechanism for adjusting the position of the running rail relative to the extendable furniture part is provided in the direction of at least one axis of one of three substantially perpendicular to each other extending coordinate axes formed Cartesian coordinate system.

Incorrect orientations of the pull-out furniture part can expediently be formed so correctable that the adjustment fitting has a bearing on the bottom of the pull-out furniture part contact element, which is arranged vertically adjustable on the running rail in the vertical direction.

The support element then expediently has a support plate mounted in a cutout of the web surface of the running rail and engageable on the underside of the extendable furniture part, and the adjusting mechanism means for changing the position of the upper side of the support plate relative to the upper side of the web surface of the running rail in the vertical direction.

To be particularly advantageous, an embodiment has been found in which of at least one of the extension in the extending lateral edges of the support plate, a leg portion is bent substantially at right angles, which (r) engages over the lateral leg of the track or over the leg or the leg portion (E) is mounted to a horizontally and at right angles to the direction of extension extending axis pivotally to the lateral legs of the track rail or are.

The height adjustment mechanism can then have a lever arm which is rotatable at one of its ends and has the associated adjacent lateral limb of the running rail, which lever is non-rotatably connected to a slot-like passage opening in the associated, unwound from the support plate lateral leg arranged eccentric component is connected. The free end of the lever arm then serves as a handle in the height adjustment, ie the use of a separate tool is not required.

5 In an advantageous embodiment of the invention, the adjustment fitting on the running rail at right angles to the withdrawal direction with lateral play cross Verstellkonsole, the body support wall facing the end horizontally and transversely to the direction of withdrawal of the track in driving connection with the extendable furniture part can be brought, in which case on the opposite tragwandabgewandten End of the Verstellkonsole on the running rail attacking means for horizontal lateral displacement l O the running rail are provided relative to the Verstellkonsole in the context of the lateral play.

The Mitnahmeverbindung de Verstellkonsole with the pull-out furniture part can then be realized, for example, by a tragwandseitigen end of the Verstellkonsole with its free end upwards vertical spigot, which in the downwardly running mouth of an on-15 bore in the bottom of the extendable furniture part can be inserted ,

The plug-in pin then has a diameter essentially corresponding to the diameter of the receiving bore in order to avoid adjusting play, the free end of the plug-in pin then being tapered in order to facilitate insertion into the receiving bore.

It is advantageous if the plug-in pin is arranged in the vertical direction in the downward direction resiliently displaceable on Verstellkonsolen-end.

25 The means for horizontal lateral displacement of the running rail relative to the extendable furniture part in a preferred embodiment on the tragwandabgewandte lateral leg of the track attacking threaded shaft on which an adjusting nut is screwed relative to the Verstellkonsole rotatable, but in the Seitenverstellrichtung with respect to the Verstellkonsole is not supported variable position on the threaded shaft.

The threaded shank then expediently secured against rotation secured to the lateral leg of the running rail, wherein the opposite end faces of the adjusting nut are overlapped by one associated with the tragwandabgewandten end of the Verstellkonsole driver. The driver (s) can then be relatively easily formed from rigidly on the associated end of the adjustment console 5 henen, at its threaded shank-side free end with an open-ended, the threaded shank encompassing slot provided Mitnehmerzunge (s) are formed. In order to prevent the pull-out furniture part - for example, at a height adjustment - is released from its driving connection with the receiving bore, it is recommended to provide a horizontal and transverse to the pull-out längshalterten elongated safety pin in the inventive development on adjustable fitting, the support wall facing free end in a on the supporting wall side leg of the running rail vortretende shift position is biased, in which engages its free end in an associated receiving opening in the extendable furniture part, then being provided on the opposite Tragwandabgewandten end of the securing bolt means for retracting the securing bolt against the spring bias in a withdrawn from the receiving opening position should.

At the tragwandabgewandten end of the locking bolt then a handle is suitably provided, the actuation causes a displacement of the locking bolt against the resilient bias in the retracted from the receiving opening position.

This handle can be designed, for example, as a rotationally fixed to the support wall facing away from the end of the locking bolt lever whose pivoting movement generated by a spatial curve guide a displacement component of the locking bolt in the retracted position from the receiving opening.

It is advantageous if a handle in the withdrawn from the receiving opening

Position of the locking bolt locking locking device is provided.

A further adjustment possibility of the extendable furniture part in the horizontal direction in the direction of travel of the rail can be realized by the fact that on the adjustment fitting a shaft which is rotatable about a horizontal and at right angles to the direction of withdrawal is rotatable on the supporting wall

Outside of the leg of the track rail provided eccentric component is provided, which is arranged in a perpendicular to the withdrawal direction perpendicular slot-shaped opening with a diameter of the eccentric component substantially corresponding width in the adjustment fitting, then means for rotating the eccentric member are provided ,

These means for rotating the eccentric component are then expediently formed on the end wall of the eccentric exposed in the slot-like opening, specifically in the form of depressions in or protrusions suitably designed for applying a rotary tool, on the end face of the eccentric.

If the extendable furniture part is then secured in the manner described by a biased, engaging in a receiving opening securing bolt against lifting from the socket pin, should the receiving opening provided for receiving the securing bolt in the pull-out furniture part in the pull-out direction has a length measured by at least twice the eccentricity of the eccentric component greater than the diameter of the end of the securing bolt engaging in the receiving opening in the pull-out direction.

In a second embodiment of the invention, the embodiment is made such that the adjustment fitting has an attachable to the underside of the extendable furniture part basic component, which engages one in the intended mounting position of the running rail of the pull-out on the extendable furniture part resiliently into a provided on the running rail latching receptacle Locking member, that the adjusting mechanism has an adjusting member with a threaded shank whose longitudinal central axis is arranged parallel to the underside of the extendable furniture part and substantially perpendicular to the running-Ausziehrichtung, and that the threaded shank of the adjusting member provided on the one hand in threaded engagement with a on the running rail or the base member Complementary mating thread is on the other hand, however, rotatably supported in the shaft longitudinal direction but immovably on the base member or the running rail.

The threaded shaft of the adjusting preferably engages in the provided on the rail complementary threaded hole and the protruding from the threaded hole free end of the threaded shaft is rotatably coupled in threaded shaft longitudinal direction, however, slidably connected to the base member.

The coupling of the threaded shaft with the base member is preferably carried out in that in the region of the free end of the threaded shaft of the adjusting member a circumferential groove is provided, in which engages a provided on the base member projection.

The projection is expediently formed by a driver plate provided on the base component with a slot-shaped opening open at the bottom whose inside width is approximately equal to the diameter measured over the groove base of the groove provided in the threaded shank and its thickness at least in that in the intended driving position within the groove lying area is approximately equal to the clear width of the groove dimensioned.

To facilitate the lateral adjustment of the pull-out furniture part, a handle for rotating the threaded shaft is advantageously provided in the region of the threaded shaft projecting from the threaded bore. ^• The handle can be formed by an enlarged diameter in relation to the threaded shaft circumferential annular flange, the outer peripheral surface with the grip increasing projections, grooves od. Like. Is provided.

Alternatively or - preferably - in addition, in the end face of the protruding from the threaded hole

End of the threaded shaft means for applying a rotary tool provided.

A height adjustment of the pull-out furniture part can be realized in the development of the invention, that in the underside of the extendable furniture part facing top of the base member extending in rail longitudinal direction recessed area is provided, in which a flush in the starting position with the top of the base member Platen-shaped adjusting slide is slidably disposed in rail longitudinal direction, the bottom of the recessed area facing bottom obliquely inclined with respect to its planar top in track longitudinal direction and that in the opposite side of the underside of the adjusting slide rail and / or the base member a transversely extending in relation to the slider adjustment edge or surface is provided, on which the inclined bottom of the adjusting slide at a displacement relative to Basic component runs up.

At the adjusting slide, a handle projecting from the area of the basic component into the area underneath the underside of the extendable furniture part is expediently attached.

In an advantageous embodiment of the invention, the locking receptacle is formed by a provided on the running rail rack-like receiving member with a number of evenly spaced perpendicular to the longitudinal direction running rails longitudinally locking teeth, wherein the resiliently engaging in latching engagement with the locking receptacle locking member at least one complementary to the between the Ratchet teeth of the locking receptacle formed intermediate spaces formed latching projection.

The in the direction of insertion of the drawer facing each other vertical locking surfaces of the locking teeth of the locking receptacle and the locking projection of the locking member are then suitably complementary obliquely aligned with each other so that the at least one locking projection at a Relatiwerschiebung the Rastorgangs relative to the locking receptacle in the insertion direction of the pull-out furniture part resiliently on the locking surface slide on the associated locking tooth and in the next following in the insertion direction gap between the locking teeth of the locking receptacle ¹ can pass. To ensure that the pull-out furniture part, z. As a drawer remains connected to a necessary in a complete removal from the furniture body with the running rail, the spaces formed between the locking teeth of the locking receptacle may be closed at its vertical upper end by an upper end wall. The underside of the end wall then forms in each locking tooth space a stop surface over which the latching projection of the locking member can only pass in the vertical direction when it against the urging him into engagement in the locking receptacle spring preload by a corresponding amount in the horizontal direction from the associated Rastzahn space is withdrawn.

For this purpose, it is advantageous if a pivotable about an axis perpendicular to the underside of the extendable furniture part axis actuating lever is provided on the base member which is so geared to the locking member that the locking member at a pivoting of the actuating lever from its initial position of the resilient engagement position is withdrawn with the locking receptacle.

In order to compensate for misalignments of drawers, in which the front drawer panel is tilted more or less deviating from the vertical, it may be advantageous in accordance with the invention, even if at the rear in the pull-out end of the track another Verstellbeschlag is provided, which functionally comparable can be formed with the adjustment fitting according to the invention. Also, a simplified version of this adjustable fitting - e.g. in the embodiment described in the unpublished earlier utility model application 20 2006 003 035.2 - comes into question here.

FIGS. 1 to 10 show a drawer 10 or partial areas of a drawer 10 in sectional views, which can be installed slidably by means of a pair of pull-out guides 20 into the body of a piece of furniture (not shown). In FIGS. 11 to 13, such a pull-out guide is shown separately, on the front-end-side front end of which an adjustment fitting 22, which is shown separately in FIGS. 14a to 19, is arranged, which enables the adjustment and alignment of the drawer 10 in the associated body.

The drawer 10 has the usual structure today, d. H. has two laterally spaced side walls 12, which are provided in its lower portion with longitudinal grooves, in which the lateral edges of the drawer bottom 14 are grooved. At the rear end of the carcass inside, the gap between the side walls above the bottom is closed by the rear wall 16. At the front, outer end of the drawer, the drawer is provided with a front panel 18 which projects beyond the end faces of the side walls 12 and the bottom 14 on all sides.

The extension guide used in the illustrated embodiment is designed as a so-called full extension, in which a fastened to the associated support wall of the body of the piece of furniture, designed as a metallic rail guide rail 24 via a likewise profiled metallic center rail 26 slidably guided by (not shown) rolling elements in the lateral edge region of the drawer on the underside of the bottom 14 mountable rail 28 carries. The adjustment fitting 22 has a in cross-section in the form of a 180 ° rotated about its longitudinal axis U-shaped mounting member 30 whose web surface 32- is arranged in a cutout 34 of the web surface 36 of the track rail 28, while of the web surface 32 of the mounting member Thigh surfaces 38 folded over at right angles in the downward direction surround the leg surfaces 40 folded over from the web surface 36 of the running rail 28 in a suitable manner. The mounting member 30 is suitable Way - z. B. by protruding from the lateral web surfaces 38 and / or the leg surface 32 and engaging in corresponding receptacles in the running rail 28 tongues - held on the running rail 28.

In the front, d. H. outside of the body or on the front panel side, a support element 42 with the top side facing the drawer bottom is mounted on the mounting element 30 so that it can be pivoted upwards about an axis extending transversely to the direction of withdrawal. For this purpose, from the leg surfaces 38 of the mounting member 30 protruding pin 44 (Figure 17) in associated holes 46 in laterally from the upper support surface of the support member 42 folded over, the mounting member laterally embracing leg surfaces 48 a.

I O

Spaced at a distance from the front panel end of the mounting member 30, a lever arm 50 is pivotally mounted on the mounting element and thus - with mounted adjustment fitting 30 - on the rail 28, which carries in the storage area a protruding to the mounting member 30 eccentric component 52 (FIG in a (not shown) slot-like passage opening in the lateral

15 leg surfaces 48 of the support element 42 is arranged. By twisting the at his free

End provided with a handle 52 lever arm 50, the eccentric component is rotated, whereby its supported in the slot-like passage opening outer peripheral surface in dependence on the eccentricity and the pivoting angle of the lever arm 50 pivoted by the support member 42 in up or down direction. In Figures 12a and 12b are two different pivot positions

20 lever arm 50 shown. It can be seen that the support element 42 during the pivoting of the

Lever arm 50 is pivoted from the initial position shown in Figure 12a in the position shown in Figure 12b by the amount hi in the vertical direction. Accordingly, therefore, a drawer mounted on the track rail 28 is raised at the gift of the lever arm 50 by the amount hi in the vertical direction. 25

In the pull-out direction behind the support element 42, an elongated narrow web portion 54 of a bow-shaped adjustment bracket 56 is mounted transversely displaceable on the web surface 32. Of the ends of the web portion 54, which is longer in the direction of displacement than the measured across the outside of the leg surfaces 38 width of the mounting member 30, each folded down tongues in the downward direction

3 O or angled portions 58, 60 integrally attached, of which on the adjacent body support wall of the drawer 10 receiving furniture part facing settlement 60 via further intermediate links an upwardly directed plug pin 62 resiliently displaceable in the downward direction holds. The upper chamfered free end of the spigot 62 engages in a provided in the lower horizontal end face of the side wall 12 of the drawer 10 Aufnahmebohrung- 64 (Figures 2, 5, 6a and 35 6b) and connects in the engaged position in the receiving bore 64, the drawers in their horizontal adjustment directions transverse to the drawer and in the withdrawal direction positively to the console 56, while a lifting, ie a displacement of the drawer in the vertical direction is not hindered. The height adjustment of the drawer by pivoting the lever arm 50 is thus not hindered by the engagement of the plug pin 62 in the receiving bore 64. The angled portion provided at the opposite end of the web portion 54 of the bracket 56 engages over the outer end face of an adjusting nut 70, which is threadedly engaged with the threaded shank 66 of an adjusting bolt 68 secured rotatably to the adjacent leg surface 40 of the rail 28

End face of the adjusting nut 70 from the material of the console 56 punched and folded over in the downward direction further tongue 72 ensures that the bow-shaped bracket 56 is displaced upon rotation of the adjusting nut 70 in each case in the transverse direction corresponding to the displacement of the adjusting nut 70 on the threaded shaft 66. The rotationally fixedly arranged on the running rail adjusting bolt thus forms by the horizontal driving connection screwed onto the threaded portion 66

Adjusting nut 70 with the tongue or angling 58 and the tongue 72, a lateral displacement of the bracket 56 and thus the drawer 10 relative to the track 28 enabling adjustment. The functional interaction and the configuration of the components of this adjusting device can be seen in particular from the enlarged partial sectional view according to FIG.

To ensure that the drawer can not unintentionally come out of engagement with the track 20 by lifting into a position in which the locking pin 62 is above the receiving bore 64, an elongated locking pin 78 is also displaceable horizontally and transversely to Ausziehrichtuπg next to the console 56 the mounting member 30 is supported. The securing bolt 78 is biased by a spring 80 (FIG. 19) toward the adjacent support wall to a position in which its free end engages a receiving opening (not shown) open in the bottom inner surface of the side wall 12 projecting downwardly in the bottom 14 , On the opposite tragwandabgewandten end of the securing bolt 78 means for retracting the securing bolt 78 are provided against the spring bias in a position withdrawn from the receiving opening genege position. These means are formed by a provided at the tragwandabgewandten end of the locking bolt handle in the form of a rotatably mounted on the safety pin lever 82 which allows rotation of the locking bolt 78 in its holder on the mounting member 30. This rotary or pivoting movement can then be converted by suitable means - for example, a spatial curve guide, not shown - in a displacement component of the locking bolt in the withdrawn from the receiving opening position. In the retracted from the receiving opening position a latching device is expediently provided which prevents unwanted reset of the locking bolt in the engaging position in the receiving opening due to the spring bias.

In addition to the adjustment of the drawer 10 in vertical vertical direction and horizontally in the transverse direction to provide the possibility of adjusting the drawer in the direction of withdrawal on the track rail 20, in addition to the support for the safety pin 78 in the support wall facing away from web surface 38 of Moπtageelements 30 a vertically extending slot-shaped or slot-like opening 86 is provided, in which a diameter in accordance with the width of the opening 86 sized Exzenter component 88 is arranged, which in turn is rotatably mounted in the facing leg surface 40 of the track rail 28. In the exposed in the slot-like opening 86 Tragwandabgewandten 5 face of the eccentric component 88 may suitably trained for applying a rotary tool

Wells or projections may be provided. In FIG. 10, a cross slot embossed in the end face of the eccentric component 88 is indicated, which makes it possible to fit a Phillips screwdriver with which the eccentric component 88 can be rotated and then, depending on its rotational position, the mounting element 30 on the track rail 28 shifts. O

Thus, this adjustment is not hindered by the engaging in the associated receiving opening in the drawer side wall locking bolt 78, the receiving opening must therefore have in the pull-out a the intended adjustment in the direction of withdrawal appropriately sized length. 5

Hereinafter, in conjunction with FIGS. 20 to 28, a second embodiment of an adjustable fitting, designated in its entirety by 122, which can be attached to the front end of a pull-out guide 120, is also described, which also enables the adjustment and alignment of a drawer 110 in an associated cabinet body. Of the drawer 110, only the side wall 112 and O, the rear wall 116 is shown in Fig. 20, while the bottom and the front panel of the drawer are not shown to reveal the view of the Verstellbeschlag 122.

The adjustment fitting has one at the bottom of the drawer, i. in the special case in addition to the inner surface of the underside of the bottom downwardly extended side wall 112 on the front panel 5 and / or the bottom of the drawer attachableπ Grundbauteil 130 on which a catch member

132 drawer bottom parallel and transverse to the direction of withdrawal of the running rail 128 of the pull-out 120 resiliently urged into a provided on the running rail 128 locking receptacle 134.

This latching receptacle is formed by a toothed rack-like receiving member provided on the running rail 128 with a number of ratchet teeth 136 running at a uniform pitch perpendicular to the longitudinal direction of the running rail. The locking member 132 in turn has complementarily formed to the intermediate teeth formed between the locking teeth 136 on tooth-like locking projections 138, so that the running rail 128 and the drawer 110 so in resiliently engaging detent teeth 136 and locking projections 138 in drawer-pull-out in form-locking engagement th are. The in the insertion position in the direction of insertion of the drawer 110 facing each other vertical locking surfaces of the locking teeth 136 of the locking receptacle 134 and the latching projections 138 of the locking member 132 are designed to be complementary inclined so that the Locking projections at a Relatiwerschiebung the locking member 132 relative to the locking receptacle 134 in the insertion direction of the drawer slide on each other resiliently and can pass into the next following in the insertion direction gap between the locking teeth of the locking receptacle 134.

5 At the upper end, the spaces between the locking teeth of the locking receptacle are closed by a vertical end wall 140, which also extends slightly beyond the free ends of the locking teeth on the projections 138 of the locking member 132. This ensures that the drawer can only be lifted from the running rail 128 when the locking member 132 is retracted by such a measure in the horizontal direction from the locking engagement with the locking receptacle 134, O that the locking projections 138 in front of the free boundary edge of the end wall 140th stand.

In the illustrated case as a plastic injection molded part locking member 132 is a receptacle 142 for the free end of a lever arm 144 a of a vertical axis pivotally mounted on the base member 130 double-armed lever 144 is formed, the second lever arm actuating actuation 144 b to retract the Locking projections 138 from the four-locking engagement with the

Locking receptacle 134 forms. On the locking member 132 is also applied to the rail side facing away from the lever arm 144b under resilient bias elongated tongue 148 which biases the double lever 144 in the sense of resilient locking engagement of the locking projections 138 of the locking member 132 into the spaces between the locking teeth 136 of the locking receptacle 134. 0

At the in the illustrated case also designed as a plastic injection molded part locking receptacle 134 is in a front panel of the drawer projecting lug 150 parallel to the drawer bottom and perpendicular to the rail longitudinal direction extending threaded bore 152 is provided with which a threaded shaft 154 of an adjusting member 156 is in Gewiπdeeingriff whose from the Gewindeboh- tion 5 vortretendes free end freely rotatable, but in threaded shaft longitudinal direction is immovably coupled to the base member 130. This coupling takes place in that in the free end of the threaded shaft 154, a circumferential groove 158 is provided, in which the lateral boundary walls of a slot 161 open at the bottom in a protruding from the base member 130 and in threaded shaft longitudinal direction in driving connection with the base member driver plate 160th O intervene. In the protruding from the threaded portion of the threaded shaft is also a
