One in the Fig. 1 to 13 illustrated embodiment of a designated as a whole with 100 pullout guide is the sliding arrangement of a (not shown) body extendable (not shown) extract on the body.

In particular, the pullout guide 100 serves for the displaceable arrangement of drawers in pieces of furniture, drawers in kitchen appliances, etc.

The pullout guide 100 includes a plurality, for example three, guide rails 102, which are movable by means of rolling elements 104 along a pull-out direction 106 relative to each other.

The pullout guide 100 in particular comprises an extraction-side guide rail 102a, which can be mounted, for example, on an extension.

Furthermore, the pull-out guide 100 comprises, for example, a body-side guide rail 102k, which can be mounted, for example, on a carcass.

In addition, in the in the Fig. 1 to 13 illustrated embodiment of the drawer guide 100 is provided as a middle rail 102m guide rail 102 is provided.

The center rail 102m is displaceably mounted by means of rolling elements 104 on the body-side guide rail 102k.

The discharge-side guide rail 102a is slidably mounted on the center rail 102m by means of rolling elements 104.

The guide rails 102 each have a substantially C-shaped cross-section.

The guide rails 102 are arranged nested one inside the other.

The center rail 102m surrounds the discharge-side guide rail 102a.

The body-side guide rail 102k surrounds the center rail 102m together with the outgoing-side guide rail 102a arranged therein.

Each of the guide rails 102 comprises rolling element raceways 108, in which the rolling elements 104 are guided.

The Wälzkörperlaufbahnen 108 extend parallel to the extension direction 106 and parallel to each other.

The Wälzkörperlaufbahnen 108 of each guide rail 102 are connected to each other by means of a rail back 110 of the respective guide rail 102.

The rail backs 110 of the guide rails 102 are all aligned parallel to each other.

In order to avoid unwanted falling out of the rolling elements 104 between the guide rails 102, it is provided in the pullout guide 100 that the rolling elements 104 are held by means of Wälzkörperkäfigen 112 in desired positions.

The Wälzkörperkäfige 112 include Wälzkörperaufnahmen 114 for receiving the rolling elements 104th

In addition, the Wälzkörperkäfige 112 each comprise a cage back 116th

By means of the cage back 116 are two rows of rolling elements 104, which run in the respective Wälzkörperlaufbahnen 108 of two adjacent guide rails 102, connected to each other.

The cage back 116 is preferably aligned at least in sections parallel to the rail back 110 of the guide rails 102.

When using three guide rails 102 according to the in the Fig. 1 to 13 illustrated embodiment of an extension guide 100, two Wälzkörperkäfige 112 are provided.

An exhaust-side rolling element cage 112a is disposed between the extraction-side guide rail 102a and the center rail 102m.

A body-side rolling element cage 112k is disposed between the body-side guide rail 102k and the center rail 102m.

As Fig. 2 can be seen, the pullout guide 100 may further be formed with a Selbsteinzugsvorrichtung 118 and / or with a damping device 120.

By means of the self-retraction device 118, the drawer guide 100 is preferably automatically brought from an at least partially extended position into a fully inserted end position.

By means of a damping device 120, an undesirably strong striking of the guide rails 102 when reaching the end position can preferably be avoided.

In order to avoid unwanted falling apart of the pullout guide 100, 100 fixed end positions are provided in the pullout guide.

In particular, a (not shown) fully inserted end position and a (shown in the figures) fully extended end position are provided.

In order to be able to stop or lock the pull-out guide 100 in the end positions, the pull-out guide 100 comprises a stop device 122.

The stop device 122 comprises an abutment-side stop device 122a and a body-side stop device 122k.

The discharge-side stopper 122a serves to fix the discharge-side guide rail 102a relative to the center rail 102m.

The body-side stopper 122k serves to fix the center rail 102m relative to the body-side guide rail 102k.

The stop device 122, in particular the stop-side stop device 122a and the body-side stop device 122k, comprises a plurality of stop elements 124, by means of which the guide rails 102 can be abutted against one another or against the roller body cages 112.

For example, an abutment member 124 may be described as a single stop member 126 (see FIGS FIGS. 12 and 13 ) or as a multiple stop element 128 (see Fig. 11 ) be formed.

A single stop element 126 is fixed to a guide rail 102 or to a roller body cage 112 and can be abutted against a (further) guide rail 102 or a (further) roller body cage 112.

A multiple stop element 128 is arranged on a guide rail 102 or a roller body cage 112 and can be abutted on one or more (further) guide rails 102 and / or on one or more (further) roller body cages 112.

A stop element 124 may be formed, for example, as a projection 130.

Such a projection 130 can be formed, for example, from a guide rail 102 or from a roller body cage 112, in particular by forming and / or punching and / or embossing.

In particular, such a projection 130 may be formed by bending out material of a rail back 110 or cage back 116.

However, a projection 130 can also be a component arranged on the guide rail 102 or on the roller body cage 112 and / or fixed. A protrusion 130 preferably protrudes into a path of movement of a guide rail 102 and / or a Wälzkörperkäfigs 112 along the extension direction 106 inside. In this way, an undesired passing of the respective guide rail 102 or of the respective roller body cage 112 by means of the projection 130 can be effectively prevented.

As in particular the Fig. 1 . 3 . 5 and 6 2, the extraction-side guide rail 102a comprises a stop element 124 formed as a pull-out stop 132 and a stop element 124 designed as a slide-in stop 134.

The body-side guide rail 102k comprises a stop element 124 designed as a pull-out stop 132 and a stop element 124 designed as a slide-in stop 134.

The pull-out stop 132 and the insertion stop 134 of the drawer-side guide rail 102a are referred to below as a pull-out stop 132a or as a slide-in stop 134a.

The pull-out stop 132 and the insertion stop 134 of the body-side guide rail 102k are referred to below as a pull-out stop 132k or as a push-in stop 134k (see FIGS Fig. 1 and 4 ).

The center rail 102m comprises two pull-out stops 132 and two slide-in stops 134, which are referred to below as pull-out stops 132m or slide-in stops 134m.

As can be seen from the attached figures, the pull-out stop 132a, the insertion stop 134a, the pull-out stops 132m, the pull-out stop 132k and the insertion stop 134k of the respective guide rail 102a, 102m, 102k are designed as projections 130 of the respective rail back 110.

The insertion stops 134m of the center rail 102m are formed by a multiple stopper member 128.

The Wälzkörperkäfige 112 are each provided with two Einzelanschlagelementen 126.

The individual stop elements 126 are arranged in particular on the respective cage back 116.

In particular, the individual stop elements 126 are fixed in a form-fitting manner to the rolling body cages 112 by means of rotary parts 136 or other fastening elements 138.

As in particular the Fig. 5 to 8 . 12 and 13 can be seen, arranged on the Wälzkörperkäfigen 112 stop members 124 are formed substantially identical.

Each of these individual stop elements 126 is designed as a shaped component, in particular as an injection-molded component.

The individual stop elements 126 are formed in particular from an elastic, resilient and / or resilient material.

Such individual stop elements 126 thus enable in particular a damped stop of components of the drawer guide 100 to each other.

This single stop elements 126 is therefore referred to below as a stop damper 140.

A stop damper 140 comprises a fastening region 142, by means of which the stop damper 140 can be fixed to a cage back 116 of a roller body cage 112, in particular can be fixed in a form-fitting manner.

Furthermore, the stop damper 140 comprises a plurality of deformation stages 144, which are arranged one behind the other with respect to the extension direction 106.

For example, it may be provided that the stop damper 140 comprises an arcuate deformation stage 146, a C-shaped deformation stage 148, an annularly closed deformation stage 150 and / or a massive deformation stage 152.

The arcuate deformation step 146 is preferably simultaneously formed as a C-shaped deformation step 148.

The C-shaped deformation stage 148 comprises one or more, for example two, deformation elements 154, which are aligned in particular obliquely to the extension direction 106 and face one another. Between the deformation elements 154, a gap is preferably provided, so that the deformation elements 154 are movable towards each other.

The deformation elements 154 are arranged in particular on the annularly closed deformation stage 150.

The annularly closed deformation stage 150 results in particular by a recess 156 in the stop damper 140, which is surrounded by two web portions 158, which extend substantially parallel to the extension direction 106.

At the annular closed deformation stage 150, the massive deformation stage 152 connects.

This massive deformation stage 152 is, in particular, a section protruding beyond the cage back 116 of the roller body cage 112 in the assembled state of the stopper damper 140 along the extension direction 106.

The massive deformation step 152 adjoins, in particular, the attachment region 142.

Finally, the stop damper 140 preferably also comprises a projection 160, which is arranged on a side facing away from the deformation steps 144 of the fastening region 142 and in particular serves for the correct alignment of the stop damper 140 in the mounted state thereof.

In particular, undesired rotation of the stopper damper 140 relative to the cage back 116 by means of the projection 160 can be avoided.

The projection 160 can be introduced in particular into a receptacle 162 corresponding thereto in the cage back 116 of the roller body cage 112.

As in particular the Fig. 5 to 8 it can be seen, the stop damper 140 at least in sections, a height H, which is greater than, for example, about 80% of a distance A of two adjacently arranged rail back 110th

The stop damper 140 protrudes on both sides beyond the cage back 116 and is therefore at a small distance perpendicular to the extension direction 106 on both sides surrounded by the rail back 110.

In this way, in particular an undesired lateral deflection of the stopper damper 140 can be effectively avoided during an operation thereof. In particular, the stop damper 140 may be supported on one or both of the adjacent rail backs 110 to avoid unwanted evasive movement.

As in particular the Fig. 8 and 11 can be seen, the multiple stop element 128 differs from a designed as a stop damper 140 Einzelanschlagelement 126 essentially characterized in that on both sides of the mounting portion 142 a plurality, in particular three, deformation stages 144 are provided.

The deformation stages 144 can be formed starting from the attachment region 142, for example, each as a massive deformation stage 152, subsequently as an annularly closed deformation stage 150 and subsequently as an arcuate deformation stage 146 and / or as a C-shaped deformation stage 148.

A height H of the multiple stop element 128 is preferably selected such that the multiple stop element 128 extends perpendicular to the extension direction 106 in both directions beyond the rail back 110 of the center rail 102m, in particular until just before the rail back 110 of the extraction side guide rail 102a and the body side guide rail 102k.

In this case, the multiple stop element 128 extends in particular over a height H of at least approximately 80%, for example at least approximately 90%, of the distance A of the rail backs 110 of the extraction-side guide rail 102a and the body-side guide rail 102k in a direction perpendicular to the extension direction 106.

In particular, the multiple stop element 128 comprises an abutment-side abutment region 164 on which the delivery-side guide rail 102a can be abutted.

Furthermore, the multiple stop element 128 preferably comprises a body-side abutment region 166, on which the body-side guide rail 102k can be abutted.

In particular, the insertion stop 134a formed as a projection 130 can be the one hand on the drawer-side guide rail 102a and the one as a projection 130 formed Einschubanschlug 134k of the body-side guide rail 102k to the multi-stop element 128 abut.

For particularly stable fixing of the multiple stop element 128 on the middle rail 102m, it may be provided, in particular, that the middle rail 102m comprises one or more bending sections 168, which are formed in particular from the material of the rail back 110 of the middle rail 102m.

By means of such bending sections 168 and / or by means of a suitably designed fastening element 138, the multiple stop element 128 can be supported in particular parallel to the extension direction 106 (see in particular FIG Fig. 8 ).

The pullout guide 100 described above functions as follows:

By moving the drawer-side guide rail 102a relative to the body-side guide rail 102k, a drawer can be pulled out of or pushed into a carcass.

By means of the stop device 122, the pullout guide 100 together with the pullout thereon can be arranged in two end positions.

The fully extended end position shown in the accompanying figures is achieved by means of the stop device 122 in that the Wälzkörperkäfige 112 are clamped between the stop members 124 of the stop device 122.

In particular, the pull-out stops 132a, 132m abut on both sides against the individual stop elements 126 of the drawer-side rolling element cage 112a. In addition, the extension stops 132k and 132m abut the single stopper members 126 of the body-side rolling element cage 112k formed as the stopper dampers 140.

The striking of the guide rails 102 to each other for fixing in the fully extended end position thus takes place indirectly, namely on the Wälzkörperkäfige 112th

When inserting the pullout guide 100 in the fully inserted end position, the arresting stops without involvement of Wälzkörperkäfige 112th

Rather, the guide rails 102 with the stop elements 124 directly abut each other.

In particular, the delivery-side guide rail 102a abuts with the insertion stopper 134a on the multiple stopper member 128 of the center rail 102m.

The center rail 102m strikes the insertion stop 134k of the body side guide rail 102k by means of the multiple stopper member 128.

In the fully inserted position of the drawer guide 100, the insertion stop 134a of the drawer-side guide rail 102a is thus applied to the drawer-side stop area 164 of the multiple stop element 128.

Further, the insertion stopper 134k of the body-side guide rail 102k is abutted on the body-side abutment portion 166 when the pullout guide 100 is disposed in the fully-retracted end position. Due to the different nature of the stop when pushing on the one hand and when pulling on the other hand, in particular an optimized correction of the positions of the Wälzkörperkäfige 112 done.

The Wälzkörperkäfige 112 can namely, because of many influences from a preferred range of motion removed (so-called cage migration). Correction of the positions of the Wälzkörperkäfige 112 can negatively affect the ease of operation or handling of the pullout guide 100 or provided with the pullout guide 100 object.

In particular, when self-retracting devices 118 and / or damping devices 120 are used, in the case of unfavorable rolling-element cage positions, it is possible that an extension arranged on the extension guide 100 can not be drawn completely into the body in an undesired manner.

Characterized in that in the described pullout guide 100, however, the insertion movement is substantially independent of the positions of the Wälzkörperkäfige 112 up to the end position, an unwanted blocking of the retraction movement or insertion movement can be effectively avoided.

By fully extending the pullout guide 100 and the associated pinching of the Wälzkörperkäfige 112 between the extension stops 132 of the guide rails 102, the Wälzkörperkäfige 112 can still be easily and conveniently, especially for a user almost unnoticeable, placed in the preferred positions.
