Description

The present invention relates to a pull-out guide for the displaceable arrangement of a pull-out on the body which can be pulled out of a body.

Such an extract guide is for example from the DE 10 2008 011 481 A1 , of the CA 1 125 346 A and the US 4,469,384 A known.

The object of the present invention is to provide a pull-out guide which is simple in construction and can be conveniently fixed in one or more end positions.

This object is achieved according to the invention by a pull-out guide for the displaceable arrangement of a pull-out on the body that can be pulled out of a body, with the features of claim 1.

The fact that the guide rails of the pull-out guide can be struck in one or more end positions by means of a stop device of the pull-out guide means that the pull-out guide can be set up easily and handled comfortably.

A striking of the guide rails in one or more end positions means in particular locking or fixing the guide rails relative to one another, in which a continuation of a relative movement of the guide rails relative to one another during a movement along an extension direction or insertion direction due to one or more obstacles along the movement path is prevented.

In one embodiment of the invention, it can be provided that the stop device comprises a pull-out stop device, by means of which a pull-out guide rail of the pull-out guide and a guide rail of the pull-out guide designed as a central rail can be attached to one another.

Alternatively or in addition to this, it can be provided that the pull-out guide can be arranged in a fully extended end position by means of the stop device, in which the guide rails are fixed directly to one another by means of stop elements.

Provision can be made for one or more stop elements to be arranged laterally offset from one another perpendicularly to an extension direction and / or to an insertion direction and / or to be movable past one another along the extension direction and / or insertion direction.

In one embodiment of the invention it is provided that the pull-out guide comprises a self-closing device, by means of which the pull-out guide can be brought from an at least partially extended position into a fully inserted end position.

In particular, if the pull-out guide includes such a self-retracting device, it is preferably provided that the pull-out guide can be arranged in a fully inserted end position by means of the stop device, in which the guide rails are fixed directly to one another, in particular directly abut one another, by means of stop elements. A possible undesired displacement of one or more rolling element cages relative to the guide rails (so-called cage movement) then preferably has no influence on the function of the self-retracting device.

In particular, it can then preferably be prevented that the retracting movement (insertion movement) of the self-retracting device is undesirably blocked due to a rolling element cage.

A correct position of the one or more rolling element cages is then preferably achieved in that the pull-out guide by means of the stop device can be arranged in a fully extended end position, in which the one or more rolling element cages are fixed between stop elements of the guide rails.

Furthermore, the body-side guide rail preferably includes a pull-out stop on which a roller body cage, in particular the body-side roller body cage, can be attached.

Furthermore, the pull-out guide according to the invention can have one or more of the features and / or advantages described below:
In principle, it can be provided that all information relating to the pull-out side or the carcase side is provided inverted. The body side then becomes the pull-out side and the pull-out side then becomes the body side.

The use of the terms "pull-out side" and "cabinet side" consequently serve in particular to simplify and illustrate the invention and are not intended to limit the invention to the corresponding specific arrangement of the pull-out guide on a body and a pull-out.

A stop element is preferably a resilient and / or elastic stop element.

In particular, if the pull-out guide comprises a self-closing device, an undesired movement of one or more rolling element cages is corrected, preferably when the pull-out guide is pulled out.

In this way, the self-retracting device can be designed with a reduced retracting force and / or preferably inexpensively.

In particular, an undesirably open pull-out, which can result from a blocking of the pull-in movement due to the undesired cage migration, can preferably be prevented in this way.

An optimized stop behavior can preferably be achieved by multi-stage stop sections, in particular by at least three-stage stop sections. In particular, unwanted rebounding or rebounding can be effectively avoided.

One or more stop elements are preferably arranged between the rail back of the pull-out guide rail and the body-side guide rail, in particular between the pull-out guide rail and the middle rail and / or between the middle rail and the body-side guide rail.

One or more stop elements are preferably dimensioned such that lateral deflection, in particular essentially perpendicular to the direction of extension and / or insertion, is effectively prevented due to an adjacent rail back.

For example, one or more stop elements have a height and / or width extending between two rail backs, which is at least approximately 80%, preferably at least approximately 90%, for example at least approximately 95%, of the distance between the two rail backs.

A stop element of the central rail preferably projects on both sides beyond a rail back of the central rail.

Furthermore, a stop element of a rolling element cage preferably projects on both sides beyond a cage back of the rolling element cage.

One or more stop elements are preferably formed from a thermoplastic material and / or an elastomer material.

The pull-out guide can preferably be locked in a first end position by clamping one or more rolling element cages. In a second end position, the pull-out guide can preferably be fixed by directly striking two or more guide rails against one another.

The first end position is preferably the fully extended end position or the fully inserted end position. The second end position is consequently the fully inserted end position or the fully extended end position.

Identical or functionally equivalent elements are provided with the same reference symbols in all figures.

One in the 1 to 13 The illustrated embodiment of a pull-out guide designated as a whole as 100 serves for the displaceable arrangement of a pull-out (not shown) on the body, which can be pulled out of a body (not shown).

In particular, the pull-out guide 100 is used for the sliding arrangement of drawers in pieces of furniture, pull-outs in kitchen appliances, etc.

The pull-out guide 100 comprises several, for example three, guide rails 102 which can be moved relative to one another along a pull-out direction 106 by means of roller bodies 104.

The pull-out guide 100 comprises in particular a pull-out guide rail 102a which can be mounted, for example, on a pull-out.

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

In addition, in the 1 to 13 In the illustrated embodiment of the pull-out guide 100, a guide rail 102 designed as a central rail 102m is provided.

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

The pull-out guide rail 102a is slidably mounted on the central rail 102m by means of rolling elements 104.

The guide rails 102 each have an essentially C-shaped cross section.

The guide rails 102 are nested.

The middle rail 102m surrounds the pull-out guide rail 102a.

The body-side guide rail 102k surrounds the center rail 102m together with the pull-out 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 rolling element raceways 108 extend parallel to the extension direction 106 and parallel to one another.

The rolling element raceways 108 of each guide rail 102 are connected to one another 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 one another.

In order to prevent the rolling elements 104 from falling out between the guide rails 102, it is provided in the pull-out guide 100 that the rolling elements 104 are held in desired positions by means of rolling element cages 112.

The rolling element cages 112 comprise rolling element receptacles 114 for receiving the rolling elements 104.

In addition, the rolling element cages 112 each comprise a cage back 116.

Two rows of rolling elements 104, which run in the respective rolling element raceways 108 of two adjacent guide rails 102, are connected to one another by means of the cage back 116.

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 1 to 13 In the illustrated embodiment of a pull-out guide 100, two rolling element cages 112 are provided.

A pull-out rolling element cage 112a is arranged between the pull-out guide rail 102a and the central rail 102m.

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

How Fig. 2 can be seen, the pull-out guide 100 can also be designed with a self-retracting device 118 and / or with a damping device 120.

The pull-out guide 100 can preferably be brought automatically from an at least partially extended position into a fully inserted end position by means of the self-retracting device 118.

A damping device 120 can preferably prevent the guide rails 102 from striking undesirably when the end position is reached.

In order to avoid undesired falling apart of the pull-out guide 100, fixed end positions are provided in the pull-out guide 100.

In particular, a fully inserted end position (not shown) and a fully extended end position (shown in the figures) 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 a pull-out stop device 122a and a body-side stop device 122k.

The pull-out stop device 122a serves to fix the pull-out guide rail 102a relative to the central rail 102m.

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

The stop device 122, in particular the pull-out 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 hit against one another or against the rolling element cages 112.

A stop element 124 can, for example, be used as a single stop element 126 (see FIGS 12 and 13 ) or as a multiple stop element 128 (see Fig. 11 ) be trained.

A single stop element 126 is fixed on a guide rail 102 or on a rolling element cage 112 and can be attached to a (further) guide rail 102 or a (further) rolling element cage 112.

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

A stop element 124 can be designed, 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 reshaping and / or stamping and / or stamping.

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

A projection 130 can, however, also be a component arranged and / or fixed on the guide rail 102 or on the roller body cage 112.

A projection 130 preferably protrudes into a movement path of a guide rail 102 and / or a rolling element cage 112 along the extension direction 106. In this way, undesired movement of the respective guide rail 102 or the respective rolling element cage 112 by means of the projection 130 can preferably be effectively prevented.

Like the one in particular Fig. 1 , 3rd , 5 and 6 As can be seen, the pull-out guide rail 102a comprises a stop element 124 designed as a pull-out stop 132 and a stop element 124 designed as a push-in stop 134.

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

The pull-out stop 132 and the push-in stop 134 of the pull-out guide rail 102a are referred to below as pull-out stop 132a and as push-in stop 134a.

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

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

As can be seen from the attached figures, the pull-out stop 132a, the push-in stop 134a, the pull-out stops 132m, the pull-out stop 132k and the push-in 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 stop element 128.

The rolling element cages 112 are each provided with two individual stop elements 126.

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

In particular, the individual stop elements 126 are positively attached to the rolling element cages 112 by means of rotating parts 136 or other fastening elements 138.

Like the one in particular 5 to 8 , 12 and 13 it can be seen that the stop elements 124 arranged on the rolling element cages 112 are essentially identical.

Each of these individual stop elements 126 is designed as a molded 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.

Single stop elements 126 of this type thus enable, in particular, a dampened stop of components of the pull-out guide 100 against one another.

These individual stop elements 126 are therefore referred to below as stop dampers 140.

A stop damper 140 comprises a fastening area 142, by means of which the stop damper 140 can be fixed to a cage back 116 of a rolling element 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 can 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 designed 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 in particular aligned obliquely to the pull-out direction 106 and project toward one another. A gap is preferably provided between the deformation elements 154, so that the deformation elements 154 can be moved towards one another.

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

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

The massive deformation stage 152 is connected to the annularly closed deformation stage 150.

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

The massive deformation step 152 borders in particular on the fastening area 142.

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

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

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

Like the one in particular 5 to 8 can be seen, the stop damper 140 has, at least in sections, a height H which is greater than, for example, approximately 80% of a distance A between two adjacent rail backs 110.

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

In this way, in particular undesired lateral deflection of the stop damper 140 when the same is actuated can be effectively avoided. In particular, the stop damper 140 can be supported on one or both of the adjacent rail backs 110 to avoid an undesired evasive movement.

Like the one in particular Fig. 8 and 11 It can be seen that the multiple stop element 128 differs from one designed as a stop damper 140 Single stop element 126 essentially in that several, in particular three, deformation stages 144 are provided on both sides of the fastening area 142.

The deformation stages 144 can, starting from the fastening region 142, each be designed, for example, as a massive deformation stage 152, subsequently as a ring-shaped 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 pulling direction 106 in both directions beyond the rail back 110 of the central rail 102m, in particular up to just before the rail back 110 of the pull-out guide rail 102a and the body-side guide rail 102k.

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 between the rail back 110 of the pull-out guide rail 102a and the body-side guide rail 102k in a direction taken perpendicular to the pull-out direction 106.

The multiple stop element 128 comprises in particular a pull-out stop area 164, on which the pull-out guide rail 102a can be hit.

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

In particular, the insertion stop 134a, formed as a projection 130, of the pull-out guide rail 102a, on the one hand, and that as a projection Strike 130 formed insertion stop 134k of the body-side guide rail 102k on the multiple stop element 128.

In order to fix the multiple stop element 128 to the central rail 102m in a particularly stable manner, it can in particular be provided that the central rail 102m comprises one or more bending sections 168, which are formed in particular from the material of the rail back 110 of the central 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 pull-out direction 106 (see in particular Fig. 8 ).

The pull-out guide 100 described above works as follows:
By moving the pull-out guide rail 102a relative to the body-side guide rail 102k, a pull-out can be pulled out of a body or pushed into it.

The pull-out guide 100 together with the pull-out arranged thereon can be arranged in two end positions by means of the stop device 122.

The fully extended end position shown in the attached figures is achieved by means of the stop device 122 in that the roller body cages 112 are clamped between the stop elements 124 of the stop device 122.

In particular, the pull-out stops 132a, 132m strike the single stop elements 126 of the pull-out rolling element cage 112a on both sides.

Furthermore, the pull-out stops 132k and 132m strike the individual stop elements 126 of the body-side rolling element cage 112k designed as stop dampers 140.

The guide rails 102 are thus struck against one another for fixing in the fully extended end position, that is to say indirectly, namely via the roller body cages 112.

When the pull-out guide 100 is pushed into the fully inserted end position, the arresting stop takes place without the involvement of the roller body cages 112.

Rather, the guide rails 102 abut one another directly with the stop elements 124.

In particular, the pull-out guide rail 102a strikes the multi-stop element 128 of the center rail 102m with the insertion stop 134a.

The middle rail 102m abuts on the insertion stop 134k of the body-side guide rail 102k by means of the multiple stop element 128.

In the fully retracted position of the pull-out guide 100, the insertion stop 134a of the pull-out guide rail 102a is thus placed on the pull-out stop area 164 of the multiple stop element 128.

Furthermore, the insertion stop 134k of the cabinet-side guide rail 102k is applied to the cabinet-side stop region 166 when the pull-out guide 100 is arranged in the fully inserted end position.

Due to the different type of stop when pushing in on the one hand and when pulling out on the other hand, in particular an optimized correction of the positions of the roller body cages 112 can take place.

The rolling element cages 112 can namely move away from a preferred range of movement due to a variety of influences (so-called cage wandering). Correcting the positions of the roller body cages 112 can have a negative influence on the operating or handling comfort of the pull-out guide 100 or of the object provided with the pull-out guide 100.

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 undesirable that a pull-out arranged on pull-out guide 100 cannot be completely pulled into the body.

Due to the fact that in the described pull-out guide 100 the insertion movement into the end position is essentially independent of the positions of the rolling element cages 112, an undesired blocking of the insertion movement or insertion movement can be effectively avoided.

By completely pulling out the pull-out guide 100 and the associated clamping of the rolling element cages 112 between the pull-out stops 132 of the guide rails 102, the rolling element cages 112 can nevertheless be brought into the preferred positions simply and comfortably, in particular almost imperceptibly for a user.
