The energy storage 144 is via a deflection device 148 guided, by means of the guide plate 118 in the vertical direction substantially in the middle and in the insertion direction E at the front end of the rail back 110 the outer rail 102 is arranged, and extends in particular starting from a fastening device 150 , for example, at a front in the extension direction A end of the guide plate 118 and / or adjacent to a front in the extension direction A end of the recess 120 in the lower leg of the outer rail 102 is arranged, first in the insertion direction E and after the deflection by means of the deflection device 148 essentially in the extension direction A to the driver 146 ,

The driver 146 has an example of the outer rail 102 facing guide pin 152 and one of the inner rail facing, in 2 . 4 and 6 shown driving pin 154 on. The guide pin 152 is in particular in a guide channel 156 the guide plate 118 guided.

The guide channel 156 is divided into a guide section 158 , which in the assembled state of the pullout guide 100 at least approximately horizontally, and a latching section 160 , which at the front in the extension direction A end of the guide portion 158 transverse to the same, in the assembled state of the pullout guide 100 for example, vertically downward or vertically upward, runs.

Especially when using two identical drawer slides 100 for a pair of pullout guides 100 to receive and guide an extract is then one of the drawer guides 100 mounted such that the locking portion 160 vertically down from the guide section 158 protrudes while the other of the pull-out guides 100 is then mounted such that the locking portion 160 vertically upwards from the guide section 158 projecting.

By means of the guide pin 152 is the driver 146 in the extension direction A along the guide section 158 and then transversely to the extension direction A along the locking portion 160 guided movable.

Because the means of energy storage 144 on the driver 146 exerted force acts substantially parallel to the direction of insertion E, the driver can 146 by moving the guide pin 152 in the rest section 160 of the guide channel 156 be brought into a detent position ( 2 and 3 ).

The driver 146 is by means of the control 140 , which on the inner rail 106 is arranged, actuated. The control 140 includes an inlet section 162 , a control channel 164 and an end portion 166 ,

The pullout guide described above 100 works as follows:
When inserting the pullout guide 100 from the fully extended state ( 2 and 3 ) becomes the inner rail 106 relative to the outer rail 102 and relative to the middle rail 104 on the front in the direction of insertion E end of the outer rail 102 arranged feeder and damping device 112 moved to, in the direction of insertion E front end of the inner rail 106 at the stop surface 130 of the actuating element 126 attacks.

This is the further insertion of the pullout guide 100 the housing 122 the damping device 114 moved in the direction of insertion E.

By this movement of the housing 122 the damping device 114 in the insertion direction E are the volume of the two interiors of the housing 122 and the pressure prevailing therein changes, wherein the movement damping fluid flows due to the pressure difference, for example through openings in the piston from one interior to the other interior. The flow rate is dictated by the size of the openings in the piston and the viscosity of the motion damping fluid. Due to the friction occurring during the passage of the openings, the kinetic energy of the inner rail is converted 106 and the extract arranged thereon into thermal energy. As a result, an insertion movement of the pullout guide 100 braked.

The operation of the damping device 114 is preferably before or during or after the start of the operation of the self-closing device 116 ,

When inserting the inner rail 106 becomes the driver 146 by means of the control 140 operated by the driving pin 154 of the driver 146 by means of the inlet section 162 in the control 140 taken and along the control canal 164 in the end section 166 of the control 140 to be led ( 4 and 5 ). By the shape of the control channel 164 and the end section 166 of the control 140 is in normal operation when inserting the pullout guide 100 the driver 146 , which is then arranged in the detent position, by means of the control 140 unlocked from this detent position. The guide pin 152 of the driver 146 is doing from the locking section 160 of the guide channel 156 led out and in the leadership section 158 of the guide channel 156 ushered.

Due to the force generated by the energy storage 144 on the driver 146 is exerted in the insertion direction E, both the driver 146 as well as the means of the driving pin 154 and the control 140 with the driver 146 latched inner rail 106 from the detent position to the fully inserted position of the pullout guide 100 drawn ( 1 . 8th and 9 ).

The operation of the damping device 114 by means of the actuating element 126 takes place preferably only by moving the inner rail 106 , The driver 146 and the actuator 126 preferably do not come in contact with each other here.

In particular, it may be provided that the control 140 and / or the inner rail 106 directly on the actuating element 126 attacks and move this in the insertion direction E, in particular push.

When removing the pullout guide 100 from the fully inserted state, a recovery of the initial state of the damping device takes place 114 by moving the housing 122 relative to the piston rod 124 in the extension direction A by means of the locking device 142 ,

The housing 122 the damping device 114 When removing the inner rail 106 by means of the locking device 142 from a first position in which the piston rod 124 maximum in the housing 122 is inserted, in a second position, in which the piston rod 124 maximum from the housing 122 is pulled out, moved, wherein in the second position, the damper-side locking element 132 with the inner rail-side locking element 138 disengages, leaving the case 122 the damping device 114 despite a further extraction of the inner rail 106 remains in the second position.

In detail, the locking device works 142 in such a way that by moving the damper-side locking element 132 the pullout guide 100 in the extension direction A, the locking part 134 along the control curve 136 and thus initially horizontally along the to the inner rail side locking element 138 staggered section 139a the control curve 136 is moved. By further displacement of the damper-side locking element 132 in the extension direction A is the locking part 134 due to its bias then along the ramp 137 the control curve 136 and thus during the movement in the extension direction A also perpendicular to the same in the vertical direction, in particular downwards or upwards, of the inner rail-side locking element 138 moved away and thus out of engagement with the inner rail side locking element 138 brought ( 2 and 4 ).

The self-closing device 116 is when pulling out the pullout guide 100 from the fully inserted state thereby returned to its initial state that the driver 146 by means of the driving pin 154 located in the end section 166 of the control 140 by removing the inner rail 106 along the guide channel 156 is moved. The driver 146 will be at the end of the guide section 158 of the guide channel 156 in its movement in the extension direction A stopped and due to the shape of the control 140 by means of the driving pin 154 along the rest section 160 of the guide channel 156 in the vertical direction, in particular down or up, moves.

With this movement of the driver 146 from the fully inserted position into the detent position is simultaneously the energy storage 144 loaded, that is the spring stretched.

When inserting and removing the pull-out guide 100 is the movement of the driver 146 from the movement of the actuator 126 essentially independent.

One in the 10 to 13 illustrated second embodiment of an extension guide 100 is different from the one in the 1 to 9 illustrated embodiment essentially in that the Selbsteinzugsvorrichtung 116 together with the damping device 114 essentially completely within the outer rail 102 is arranged.

In particular, the Selbsteinzugsvorrichtung 116 and the damping device 114 between two thighs 170 the outer rail 102 arranged.

The pullout guide 100 according to the 10 to 13 differs in particular characterized by the previously described pullout guide 100 that the control 140 swiveling on the inner rail 106 is arranged.

The control 140 is in particular about a pivot axis 172 pivotable on an inner side of the inner rail 106 arranged.

The pivot axis 172 is in particular perpendicular to the rail back 110 the inner rail 106 and thus also perpendicular to the extension direction A and perpendicular to the insertion direction E.

For the pivotable arrangement, for example, a center between the two legs 170 the inner rail 106 arranged attachment opening 174 in the inner rail 106 intended. This can be the control 140 be determined for example by means of a pin, a screw, a rivet connection or the like movable.

The control 140 further preferably comprises a stop element 176 ,

By means of the stop element 176 In particular, a freedom of movement of the control 140 be restricted. In particular, a maximum pivot range of the control 140 be specified.

The stop element 176 is in particular by a stop projection 178 educated.

The stop tab 178 protrudes in particular from the control 140 in the direction of the rail back 110 the inner rail 106 path.

In particular, the stop projection extends 178 in a recess 180 into it.

The recess 180 is especially in the rail back 110 the inner rail 106 educated.

The stop tab 178 is preferably smaller in size than the recess 180 , which ultimately gives the scope of movement of the control 140 is given.

The control 140 further comprises one or more, in particular two, guide projections 182 ,

The Leitvorsprünge 182 protrude in particular in a direction perpendicular to the extension direction A and perpendicular to the insertion direction E and at the same time parallel to the rail back 110 the inner rail 106 extending direction over one or both legs 170 the inner rail 106 out.

However, it can also be provided that only a single guide projection 182 over a thigh 170 the inner rail 106 protrudes.

Alternatively or additionally, it may be provided that one or more guide projections 182 in the insertion direction E via one of the self-closing device 116 facing end 184 the inner rail 106 protrude.

The pullout guide 100 according to the 10 to 13 preferably comprises one or more fins 186 ,

The one or more fins 186 in particular serve the installation and / or management of the control 140 ,

The one or more fins 186 are in particular with the one or more Leitvorsprüngen 182 of the control 140 engageable.

Preferably, the pullout guide comprises 100 two or more fins 186 which is a guiding channel 188 form.

By means of such a Leitkanals 188 are in particular two facing away from each other Leitvorsprünge 182 of the control 140 receivable and feasible.

The opposite ends 190 the facing away from each other Leitvorsprünge 182 preferably have a distance from each other, which is substantially the distance of the guide surfaces 186 which the guiding channel 188 form, equal or slightly smaller than this distance.

In this way it can be ensured that the control 140 by means of the guide projections 182 and the fins 186 For example, is moved as exactly as possible parallel to the insertion direction E and / or parallel to the extension direction A.

The control 140 is thus particularly reliable relative to the driver 146 positionable.

Due to the pivotable arrangement of the control 140 on the inner rail 106 Thus, in particular, regardless of a load-dependent deformation or deflection of the self-closing device 116 facing end 184 the inner rail 106 a reliable coupling and decoupling of the control 140 with the driver 146 be guaranteed.

In particular 13 it can be seen is the control 140 in different pullout positions of the pullout guide 100 completely outside the conduit 188 arranged.

When inserting the pullout guide 100 must therefore be ensured that the control 140 reliable in the guide channel 188 arrives.

The pullout guide 100 for this purpose comprises one or more deflection surfaces 192 which is at a contact of the control 140 with one or more other components of the pullout guide 100 to a pivotal movement of the control 140 around the pivot axis 172 lead and the control 140 thus bring into a pivot position, which is the insertion of the control 140 in the guide channel 188 allows.

One or more deflection surfaces 192 are for example on the control 140 , in particular at the one or more guide projections 182 , arranged and / or trained.

Alternatively or additionally, it can be provided that one or more deflection surfaces 192 on other components of the pullout guide 100 , For example, a spring receiver 194 and / or a damper mount 196 , are arranged.

The spring recording 194 is in particular a housing for receiving a example as a tension spring 143 serving energy storage 144 the self-closing device 116 ,

The damper mount 196 is in particular a receptacle for the damping device 114 , especially for the housing 122 the damping device 114 ,

The spring recording 194 For example, also a guide surface 186 have or form.

Furthermore, the damper mount 196 preferably a guide surface 186 have or form.

In particular, by means of mutually facing boundary walls 198 the spring recording 194 on the one hand and the damper mount 196 on the other hand two baffles 186 for the formation of the Leitkanals 188 educated.

As in particular the 12 and 13 it can be seen, is a leg 170 the inner rail 106 formed shortened, so that the self-closing device 116 facing the end 184 the inner rail 106 is formed asymmetrically. This allows in particular easy accessibility of the control 140 ,

The control 140 can thereby in particular with the damping device 114 be engaged to operate them.

The control 140 has for this purpose in particular by a Leitvorsprung 182 formed inner rail-side locking element 138 on, which with the damper-side locking element 132 can be brought into engagement.

Regarding the functioning differs in the 10 to 13 illustrated embodiment of the pullout guide 100 from in the 1 to 9 illustrated embodiment substantially by the pivotal arrangement of the control 140 , The operation of the pullout guide 100 does not change for a user. However, there is an increased reliability at different load conditions, for example, when too heavy a load by means of the pullout guide 100 guided extract, resulting in an undesirable deformation and / or deflection of the inner rail 106 can result.

For example, in the in the 1 to 9 illustrated embodiment of the pullout guide 100 can cause excessive deformation and / or deflection of the inner rail 106 a blockage of the self-closing device 116 and / or the damping device 114 result if the associated components of the drawer guide 100 wedge or otherwise strike each other.

Through the swiveling control 140 the pullout guide 100 according to the 10 to 13 This undesirable effect can at least be reduced or completely eliminated.

In particular, by the deflection surfaces 192 be assured that the control 140 when inserting the pullout guide 100 is pivoted into a position which the introduction into the guide channel 188 allows.

Within the control channel 188 then results from the leadership of Leitvorsprünge 182 at the fins 186 a reliable and always substantially identical positioning of the control 140 relative to the driver 146 and / or relative to the guide plate 118 ,

The coupling of the control 140 with the driver 146 This makes it less prone to failure.

In addition, this may be a direction-dependent impairment of the coupling, in particular depending on a mounting of the pullout guide 100 on a right or left side of an excerpt, be avoided.

Incidentally, the right in the 10 to 13 illustrated embodiment of the pullout guide 100 in terms of structure and function with in the 1 to 9 illustrated embodiment that reference is made to the above description in this respect.
