Well recognizable is a hook element 101 as well as a retaining nose 102 that of a locking element 103 is formed at its free end. The hook element 101 therefore has a hook. 2a also shows the track 7 the pullout guide 6 , The track 7 here has a U-shaped cross-section. A bar of the track 7 has a latching window in its edge area 9 on.

In 2 B is the arrangement off 1b shown slightly enlarged, with the furniture body 1 was also omitted. The edge area of the web of the track rail 7 engages in a hook mouth of the hook, so that the hook of the hook element 101 the edge region of the web of the running rail 7 encloses and rests the end of the web to rest on the bottom of the hook mouth of the hook. The retaining nose 102 the locking element 103 grabs the rest window 9 of the dock. This is the drawer 2 advantageously almost free of play on the pullout guide 6 locked or fastened. The achievement of the backlash of the lock will be described in more detail below.

In 3 is the coupling device 100 and their individual parts clearly visible. The coupling device 100 has a base element 104 on. The basic element 104 has a cuboid basic geometry and serves for receiving, for attachment and as a guide partner of other items of the coupling device 100 ,

The basic element 104 has a breakthrough 105 with a substantially rectangular cross section. The breakthrough 105 also has two undercuts 106a . 106b on. Into the undercuts 106a . 106b engages a spring arrangement, implemented here as a trapezoidal spring 107 , with her two free ends. This creates a positive connection between the base element 104 and the trapezoidal spring 107 , The trapezoidal spring 107 is made of a flat material as a bent part.

The basic element 104 also has a recess 108 on, which is designed so that through the recess 108 a locking spring arrangement 109 with a base element-side free end form-fitting with the base element 104 is connectable.

In the assembled state of the housing plate 115 reaches through a screw 120 the through hole 119 and the threaded hole 117 , With the screw 120 can therefore over the threaded hole 117 the inclination of the base element 104 relative to the housing plate 115 be set. In the assembled state of the coupling device 100 lies the housing plate 115 at the respective frame 3 of the drawer 2 and is attached to it. Through the screw 120 can thus a lateral adjustment of the drawer 2 will be realized.

The coupling device 100 also has a slider 121 on. The slider 121 has guide surfaces 122 a slide on which he slidably on the base element 104 is guided. The basic element 104 has correspondingly geometrically corresponding guide surfaces 123 on. The guide surfaces 122 . 123 or the sliding guide are / is here designed so that in the mounted state of the slider 121 on the base element 104 gives a kind of flat guide. The type of sliding can also be performed geometrically different.

The slider 121 has at least partially a U-shaped cross-sectional geometry, so that the slide 121 is executed like a box. The slider 121 also has the hook element at a free end 101 on. On an inner side of a leg of the C-shaped cross section of the slider 121 is the detent plate 114 here by a rivet connection form-fitting with the slide 121 connected. In this case, the locking teeth 113 to the inside of the U-shaped cross section of the slider 121 ,

On the slider 121 is also the locking element 103 movable, preferably pivotally mounted. This is the locking element 101 on the box-like inside of the C-shaped cross section of the slider 121 on. The retaining nose 102 the locking element 103 points in the same direction as the hook element 101 of the slider 121 , The slider 121 is designed so that the retaining lug 102 can be pivoted out of the C-shaped cross section addition. This is indicated by the slider 115 a recess 124 on.

Furthermore, the locking element 103 a first tab 125 and a second tab 126 on. The tabs 125 . 126 For example, each made by a Abkantprozess and designed so that through the tabs 125 . 126 mentally at least partially U-shaped cross-section of the locking element 103 arises.

In 4a is the drawer 2 shown in a partial plan view. In an initial state shown here of a locking operation of the drawer on the pullout guides 6 (not shown here) together with the coupling device 100 is the front panel 5 from furniture corkups 1 with the distance A spaced.

In 4b is the drawer 2 in section through the coupling device 100 shown. The coupling device 100 is shown in the assembled state. It can be clearly seen that the coupling device 100 in the neckline of the frame 3 of the drawer 2 is used.

Also clearly visible is the locking element 103 , here in the unlocked state, the movable, preferably pivoting in the slide 121 is stored. The second tab 126 the locking element 103 relies on a backdrop 127 from. Also well recognizable is the trapezoidal spring 107 , with their two free ends in the undercuts 106a . 106b intervenes.

The track 7 the pullout guide 6 is located on one of the webs of the U-shaped cross section of the slider 121 at. The locking window is also clearly recognizable 9 in the track 7 , also the hook element 101 that the slider 121 formed. The hook or hook mouth of the hook element 101 is designed so that there is a bar of the track 7 can enclose on three sides. Furthermore, the locking plate 114 with the ratchet teeth 113 clearly visible. Likewise, the locking spring arrangement 109 clearly visible, with their central body facing the free end in the recess 111 of the base element 104 supported. The tongue 110 the locking spring arrangement 109 engages in this initial position of the locking operation in a tooth gap of the locking teeth 113 one, the furthest toward the front panel 5 is arranged. The release button 112 is therefore not actuated, but is with her the locking spring assembly 109 facing free end of the locking spring assembly 109 at.

Accordingly, the slider 121 and the base element 104 complementary locking means -also the locking spring arrangement 109 or the tongue 110 as well as the detent plate 114 or the locking teeth 113 - on, leaving the base element 104 and the slider 121 can be latched relative to each other in different locking positions.

The locking means 109 . 110 . 113 . 114 advantageously serve for safe installation of the front panel 5 on the furniture body 1 when completely in the furniture body 1 inserted drawer 2 , as well as also advantageous for tolerance compensation.

In 5a is the drawer 2 shown in a partial plan view. In the state of the locking process of the drawer shown here 2 on the pullout guides 6 (not shown here) by the coupling device 100 is the front panel 5 from the furniture body 1 with a distance B spaced apart, the distance B less than the distance A in 4a respectively. 4b , Ie, that's the drawer 2 continue to the pullout guide 6 was postponed.

Compared to 4b encloses in 5b the hook of the hook element 101 the front panel-side free end of the track 7 the pullout guide 6 , So that the front panel-side free end comes to rest on the bottom of the hook mouth, that the hook element 101 formed.

This is the pullout guide 6 through their track 7 on three sides of the hook element 101 of the slider 121 encompassed. It results so advantageous a defined distance between the bottom of the hook mouth of the hook element 101 to the rest window 9 the track 7 ,

Also in 6a is the drawer 2 shown in a partial plan view. In the state of the locking process of the drawer shown here 2 on the pullout guides 6 (not shown here) by the coupling device 100 - Also called Nachverrastung- is the front panel 5 from the furniture body 1 with a distance C spaced apart, the distance C less than the distance B in 5a respectively. 5b , This in turn means that the drawer 2 continue towards the furniture carcass 1 was pushed. This is possible although the track rail 7 the pullout guide 6 already at the bottom of the hook mouth of the hook element 101 abuts, since the base element 104 (not shown here) relative to the slider 121 is displaceable.

Compared to 5b has moved through the movement of the base element 104 in the direction of the rear wall (not shown here) of the drawer 2 relative to the slider 121 the locking element 103 also relative to the pullout guide 6 postponed.

This became the first tab 125 the locking element 103 on a surface 128 the trapezoidal spring 107 deferred, parallel to the free ends of the trapezoidal spring 107 is arranged. This has the locking element 103 a pivotal movement counterclockwise about its pivot point P completed, so that the retaining lug 102 the locking element 103 now the rest window 9 be upheld. This is the pullout guide 6 over the coupling device 100 with the drawer 2 locked. By the trapezoidal spring 107 becomes a steadily acting force on the locking element 103 exercised, which ensures that the retaining lug 102 sure the rest window 9 be upheld.

The retaining nose 102 has a bevel on its side facing the front panel 129 on (see also 3 ). Due to the bevel dimensional tolerances of the hook element 101 be balanced so that the bevel 129 advantageously ensures a quasi-free, fixed locking.

Furthermore, the locking spring arrangement 109 also relative to the slider 121 and thus relative to the detent plate 114 postponed. This now engages the tongue 110 the locking spring arrangement 109 in a tooth gap of the locking teeth 113 one towards the front panel 5 behind the tooth gap, the furthest in the extension direction of the drawer 2 is located.

In the in 7a illustrated state of the drawer 2 on the pullout guides 6 (not shown here) by the coupling device 100 , is the front panel 5 of the drawer 2 from the furniture body 1 with a distance D spaced apart, the distance D again smaller than the distance C in 6a , or 6b. This means again that the drawer 2 continue towards the furniture carcass 1 was pushed, leaving a gap between the front panel 5 and the furniture body 1 was further minimized. This is possible although the track rail 7 the pullout guide 6 already at the bottom of the hook mouth of the hook element 101 abuts, since the base element 104 (not shown here) relative to the slider 121 is displaceable.

This is in 7b clearly visible. In the following, essentially differences or additions to 6b described. Compared to 6b has moved through the movement of the base element 104 in the direction of the rear wall (not shown here) of the drawer 2 relative to the slider 121 the locking spring arrangement 109 also relative to the slider 121 and thus to the locking plate 114 postponed.

This now engages the tongue 110 the locking spring arrangement 109 in a tooth gap of the locking teeth 113 a, which is located between the tooth gap, which is arranged furthest in the extension direction and a tooth gap, the furthest in the direction of the rear wall (not shown here) is located

In 8a is the drawer 2 shown in a partial plan view. In the state of the locking process of the drawer shown here 2 on the pullout guides 6 (not shown here) by the coupling device 100 , lies the front panel 5 on the furniture body 1 at. This is possible although the track rail 7 the pullout guide 6 already at the bottom of the hook mouth of the hook element 101 abuts, since the base element 104 (not shown here) relative to the slider 121 can be moved.

This is in 8b clearly visible. Compared to 7b has moved through the movement of the base element 104 in the direction of the rear wall (not shown here) of the drawer 2 relative to the slider 121 the locking spring arrangement 109 also relative to the slider 121 and thus to the locking plate 114 postponed.

This now engages the tongue 110 the locking spring arrangement 109 in the tooth gap of the locking teeth 113 a, which is located furthest towards the rear wall (not shown here).

By the locking teeth 113 with multiple tooth gaps, it is possible depending on the tolerance that this tooth gap is not achieved, although the front panel 5 for attachment to the furniture body 1 has come.

In 9a is the drawer 2 shown in a partial plan view. In the state shown here at the beginning of a release operation of the drawer 2 from the pullout guides 6 (not shown here) by the coupling device 100 , lies the front panel 5 on the furniture body 1 at.

This is in 9b shown. Compared to 8b is in 9b the release button 112 pressed, leaving the tongue 110 the locking spring arrangement 109 from the ratchet teeth 113 has solved. The actuation of the release button 112 is manually possible because the geometry of the respective recess 8th the respective frame 3 is dimensioned such that such a manual or manual operation of the release button 112 is possible. This allows the front panel 5 and with it the drawer 2 in total of the furniture body 1 be moved away in the extension direction, so that again a gap with a distance e can form.

This is in 10a and in 10b shown. Through the actuated release button 112 is the tongue 110 the locking spring arrangement 109 no longer engaged with the locking teeth 113 , so that by the Relativverschiebbarkeit of the slider 121 to the base element 104 the front panel 5 and with it the drawer 2 in the extension direction of the furniture body 1 move away.

In 10b is a state of the release process shown, in which the first tab 125 of the locking element 103 the area 128 the trapezoidal spring 107 left and the second tab 126 the locking element 103 to the backdrop 127 runs. In this respect, the locking element 103 a pivoting movement in the clockwise direction about its pivot point P executed. However, the retaining lug attacks 102 still in the rest window 9 one.

Through the scenery 127 becomes with further movement of the drawer 2 in the pull-out direction -so away from the furniture body 1 - The locking element 103 continue in the clockwise direction around its fulcrum P pivoted. As a result, the retaining nose wanders 102 of the locking element 103 from the rest window 9 like this in 11b clearly recognizable.

Thus, the initial state is after 4a , or 4b reached again, leaving the drawer 2 from the pullout guide 6 can be lifted.
