Description

Pull-out guide for a drawer and method for attaching a drawer to a drawer slide

The present invention relates to a drawer slide for a drawer, with a fixable on a carcass guide rail and a movably mounted track rail, optionally between the guide rail and track rail at least one middle rail may be provided, and on the running rail a fastening device is provided with a holder on which a drawer is fixable, and a method for attaching a drawer to a drawer slide.

EP 1 147 725 discloses a pull-out guide for drawers in which a height-adjustable retaining lug is provided on a running rail, which can be inserted into an opening on the drawer in order to adjust the inclination of the front panel. Although the height adjustment permits a certain degree of flexibility, manufacturing tolerances can also occur in the longitudinal direction of the running rail, so that the fixing of the drawer between the retaining lug and another fastening means on the running rail can be complicated. For the fixation of the drawer then reworking may be required. In an unfavorable case, the retaining lug engages only a small portion of its length in the drawer, so that when a tilting moment that can arise when opening or closing a drawer, the force can be introduced into the retaining lug to deformation or failure. In WO 2010/020496 a pullout guide is proposed in which a catch hook for securing the drawer to the running rail is arranged on the running rail. The catch hook is designed as a separate, fixed to the track rail element, wherein between the catch hook and the drawer, a spring element may be provided to resiliently support the drawer rear wall on the fishing hook. As a result, although a certain tolerance compensation is possible, however, the catch hook remains rigidly fixed to the running rail. Unfavorable here is the introduction of force in the fishing hook, as well as the catch hook tolerance caused a certain distance may have to the drawer rear wall and therefore engages in the worst case only with a small portion of its length in the drawer.

It is therefore an object of the present invention to provide a pull-out for a drawer, which allows easy installation of a drawer and also can compensate for length tolerances and / or a depth adjustment of the drawer. Furthermore, a method for fixing a drawer to a pullout guide to be created. This object is achieved with a pullout guide with the features of claim 1 and a method with the features of claim 23.

According to the invention, a fastening device with a holder is provided on the running rail, on which a drawer can be fixed, wherein the holder is displaceably mounted in the longitudinal direction of the running rail and is biased via an energy store to the front in the longitudinal direction of the pullout guide. If a drawer is mounted on the track, the holder is moved against the force of the energy storage to the back of a furniture body, so that manufacturing tolerances of the drawer, the guide rail or the track can be compensated. In addition, tolerances in components of the fastening device can not adversely affect the assembly. Due to the displaceable mounting of the holder, a depth adjustment in the longitudinal direction of the running rail can also be carried out in a simple manner, since the holder is displaceably mounted anyway, so that the drawers are adjustably fixed in this direction to the holder by a suitable adjusting device. In addition, the drawer may be held by the biasing of the holder substantially non-positively on the running rail, so that a disturbing game is avoided. By moving the holder assembly is further facilitated because the user senses during assembly, whether the drawer has been correctly brought into engagement with the holder and is moved.

For a simple mounting of the fastening device, a guide may be provided for the holder, which is held on the side of the running rail. As a result, the overall height is not adversely affected by the fastening device. The guide may be formed in an additional component or else integrally with the running rail. For a compact construction, the slidable holder may have an upper protrusion insertable into a receptacle or a holding device on a rear wall of the drawer, and a lower guiding portion movable along a guide. As a result, the holder has a substantially U-shaped construction and can be produced as a bent metal sheet or plastic part.

To fix the drawer may be provided on the running rail in addition to the sliding holder further fastening means, so that the drawer attached to the running rail, in particular can be locked and is secured against lifting. The installation of the drawer to the holder can be done without tools, which facilitates the removal and placement of the drawers. The holder is preferably biased by a spring which is stretched between a housing of the fastening device and the holder. The spring can be designed as a tension or compression spring, in particular as a helical spring. Instead of the spring, other types of force stores, e.g. elastic and / or compressible elements made of elastomeric mate- rial or rubber can be used. The spring can be arranged approximately parallel in the longitudinal direction of the pullout guide, but it can also be arranged inclined to the longitudinal direction of the pullout guide or to the horizontal, whereby in addition to the main direction of action parallel in the longitudinal direction of the pullout guide one or more force components in addition the holder in at least one further direction can pull or push perpendicular to the extension direction.

The holder is adjustable in an advantageous embodiment in a horizontal direction perpendicular to the longitudinal direction of the running rail. As a result, the positioning of the drawer in the horizontal direction can be adjusted by the holder. For this purpose, for example, the guide with the holder can be mounted pivotably on a housing of the fastening device. Alternatively, an adjusting eccentric, a cam guide or other mechanism may be provided to adjust the holder in the horizontal direction perpendicular to the longitudinal direction of the track rail.

In a further embodiment, the holder and / or drawer is adjustable in height relative to the running rail. For this purpose, a support for the drawer, the holder and / or a holding device on the rear wall allow the drawer a corresponding height adjustment. Due to the height adjustment, the position of the drawer is changed relative to the running rail, which can be done by the height adjustment and tilt adjustment on the front panel.

According to a further embodiment of the invention, the holder is displaceable along a guide which is oriented inclined to the horizontal. This embodiment allows a clamping fixation of the drawer to the running rail or an associated component, wherein the guide preferably falls down towards the rear and thereby clamping forces can be applied to the drawer perpendicular to the longitudinal direction of the running rail when moving the holder. This allows a particularly stable and backlash-free fixation of the drawer. According to a further embodiment, the drawer has a recess in the middle region on the bottom, the opening is thus not on the rear wall, but on the one wall of the recess.

According to a further embodiment variant, the holder extends laterally inwards towards the middle of the drawer. The holder with its projection and its "lower guide section" are tilted by 90 ° to the drawer center. At the drawer, instead of an opening in the rear wall, e.g. an angle plate arranged on the drawer bottom, which includes an opening. The holder is coupled via the angle plate with the Schunkasten.

The pull-out guide according to the invention is used in particular for furniture or household appliances to fix a drawer between two pullout guides.

The term drawer is understood to include all types of drawer elements that are moved by means of drawer guides, such as shelves or wire baskets. The invention will be explained in more detail below with reference to several embodiments with reference to the accompanying drawings. Show it: Figure 1 is a perspective view of a drawer with a pull-out guide according to the invention during assembly;

Pull-out guide for a drawer.

A drawer 1 comprises a front panel 2, a rear wall 3 and side walls 4, the front panel 2 and rear wall 3 interconnect. Further, a bottom 5 is provided, the front panel 2, rear wall 3, side walls 4 and bottom 5 may be made of wood, metal or other material.

On the rear wall 3, two recesses 6 are provided, on each of which a pullout guide 8 is mounted. Further, above the recess 6, an opening 7 is provided in the rear wall 3, in which a projection 22 of a holder 21 can be inserted to fix the drawer 1 to a running rail 10 of a pullout guide 8. The pullout guide 8 may be formed as a full extension and a fixable to a carcass guide rail 9 and a middle rail 1 1, on which the running rail 10 movably mounted is. On the running rail 10, a fastening device 20 is further fixed in the rear region, to which the holder 21 is slidably mounted.

For assembly, the drawer 1 is first placed with the bottom 5 on the two rails 10 on opposite sides and then pushed back until the projection 22 engages the holder 21 in the opening 7, as shown in Figures 2A and 2B is. When the projection 22 has completely penetrated into the opening 7, a vertical leg of the holder 21 or a corresponding shoulder comes to rest against the drawer rear wall 3. Thus, the holder is coupled to the drawer 1 and moves along with the pushing box 1 together with this in the direction of its final assembly position. Here, the distance between the holder and the drawer rear wall does not change, or only insignificantly, e.g. due to a change in height of the drawer support.

The drawer 1 is moved rearwardly against the force of a spring or other force accumulator, which biases the holder 21 towards the front against a front stop on a cover 62. The drawer 1 can then be fixed by fastening means, not shown, on the running rail 10, for example by latching. Such devices for fastening a drawer to the running rail are known, for example, from DE 10 2013 104 829 and can be provided with a depth adjustment for the drawer. The drawer has thus reached its final assembly position. The fastening device 20 is shown in detail in FIGS. 3 and 4.

The fastening device 20 comprises in the upper region a pin-shaped projection 22 oriented towards the front side and a web 23 arranged underneath, which is linearly displaceable along a guide 50. The sliding path is limited to the rear by a rear wall 53 on the guide 50 and forward by a cover 62 which is latched to the guide 50. The guide 50 forms a groove 51, on whose side walls inwardly projecting teeth 52 are provided, which are in engagement with teeth 25 of the holder 21, when the holder 21 has been pushed in the guide 50 to the rear. In the front region of the guide 50, no teeth 52 are provided on the side walls of the groove 51.

The holder 21 is biased in the opening direction by a force accumulator in the form of a spring 28, which is designed as a helical spring. An end 27 the spring 28 is fixed to a receptacle 26 of the holder 21 on the web 23. An opposite end 29 of the spring 28 is held on an angled portion 31 of a housing 30 of the fastening device 20, wherein at the portion 31 for this purpose a receptacle 32 for inserting the end 29 is provided. Alternatively, the opposite end 29 of the spring 28 can also be held indirectly or directly on the running rail, for example on an angle piece formed integrally from the running rail.

A particularly advantageous effect of the invention is that the biasing of the holder relative to the drawer an improved force on the projection 22 of the holder 21 results over the prior art .. When a fully loaded drawer is pulled out, or in case of incorrect operation, it happens that it tilts about its horizontal transverse axis, whereby the projection 22 of the holder 21 is loaded as a lift-off from bottom to top. A lifting force F tries to upstand the projection 22 upwards. The force F acts on the outer edge of the rear wall 3. If there is now a distance of x mm between the rear wall and the vertical leg of the holder 21, thus a bending moment of F * x acts on the holder.

The distance x is dependent on the length tolerances of the furniture and guide components, as well as the length of the depth adjustment and can be several mm.

Characterized in that in the invention, the hook 21 is always pressed by spring force against the drawer rear wall, the distance x is set completely or almost to zero mm, and there is almost no bending moment acting on the projection.

The fastening device 20 is designed so that an adjustment of the drawer 1 in both the height and in the lateral direction is possible. In addition, a depth adjustment parallel to the longitudinal direction of the running rail 10 is possible.

For a height adjustment, a slider 46 is provided on the housing 30, which has inclined to the horizontal aligned slots 47. In the slots 47 pins 48 are arranged, which are fixed to openings 35 of a web 34 of the housing 30. At the end of the web 34, a rear wall 33 is provided. To adjust the slider 46 in height, located on the housing 30, a knurled nut 38 with an internal thread, which is stationary between two bent tabs 36 in the axial direction, but at bearings 37th is rotatably mounted. In the knurled nut 38, a threaded bolt 39 is arranged, which is rotationally fixed, but axially displaceable. The threaded bolt 39 is connected to a block 40 with a lever 43, wherein on the lever 43 a bendable bearing pin 42 is provided, which can be latched at an opening 41 of the block 40. On the opposite side of the lever 43 is locked by a bendable bearing pin 44 in an opening 45 on the slider 46. When the knurled nut 38 is rotated, the threaded bolt 39 moves in the axial direction and pulls or pushes the lever 43 accordingly to move the slider 46. The slider 46 is moved over the guide of the two slots 47 at the pin 48 obliquely to the horizontal and thereby an upper bearing surface of the slider 46 is moved relative to the housing 30 and the running rail 10 up or down. Since the drawer 1 is supported with the bottom 5 or the side wall 4 on the support surface of the slider 46, thus the height position of the drawer 1 is adjusted relative to the running rail 10.

During assembly, the drawer is first moved to the projection 22 on the holder 21. The holder 21 for receiving the drawer 1 on the running rail 10 is biased by a spring, as it were in a waiting position on a front stop. The altitude of the holder 21 is predetermined.

The drawer is then placed on the track 10, and the holder 21 is first pushed together with the drawer in its final final position. This end position can be different due to tolerances. Nevertheless, the connection of the holder 21 to the drawer by the spring force in each Endlagenensituation is perfect. Regardless of the length tolerances of the components and the adjustment of a depth adjustment is thus ensured that the projection (22, 82, 122) mounted drawer with at least 80% of its length in the drawer (1) and / or in a holding device (70) the rear wall (3) of the drawer (1) is immersed.

The height adjustment of the slider 46 is independent of the projection 22 and the holder 21st Adjustment is usually done with the drawer removed. In the figure 1 it can be seen that the thumbwheel is not accessible with partially deferred drawer.

To adjust the height of the drawer 1 is released from the front mounting device on the running rail 10 and over a distance of about 10cm pulled down from the holder / track forward, still partially resting on the track.

Now you have access to the knurled nut 38. About the knurled nut 38, the slider 46 can then be adjusted in height. The drawer 1 is then moved backwards until the opening 7 meets the holder 21. If the projection 22 is completely inserted into the opening 7, the holder 21 moves counter to the spring force together with the drawer. This then hits with its bottom on the inclined ramp of the slider 46 and runs the slope up to the other height level. In this case, the holder 21 (also in terms of height) is taken. When moving on, the teeth 25 of the holder engage in the teeth 52 of the guide 50 and thus prevent lifting of the drawer upwards. The height adjustment is made in this embodiment, not with mounted drawer, but at least partially disassembled drawer.

The fastening device 20 further enables lateral adjustment of the position of the drawer 1. For this purpose, the guide 50 is pivotally mounted on the housing 30. The guide 50 is formed as a lever, at one end 54, a bearing sleeve 55 is provided, which is penetrated by a vertical bearing pin 56. The vertical bearing pin 56 is also rotatably mounted on a bearing opening 57 on the housing 30. In a central region of the guide 50, a threaded opening 58 is formed on a web, in which a threaded bolt 61 of a screw 60 is screwed. The screw 60 includes a gap between a ring 67 and a screw head to which a wall of the housing 30 is inserted adjacent to a slot 59, so that the screw 60 is held non-displaceably in the axial direction on the housing 30. If the screw 60 is now rotated, the distance between the wall of the housing 30 with the slot 59 and the guide 50 changes. As a result, the guide 50 pivots about the bearing pin 56, whereby the position of the holder 21 in a horizontal direction perpendicular to the longitudinal direction the running rail 10 changes.

When the drawer 1 is removed, it is to be prevented that the holder 21 is removed from the guide 50. Therefore, a cover 62 is provided on the guide 50 in the front region, which is latched to the guide 50. The cover 62 is substantially U-shaped, whereby are provided on both legs of the U two webs 63, of which a web has an opening 64. When attaching the cover 62 to the two webs of the guide 50, a latching projection 65 reaches the opening 64 at a web and thus prevents accidental disassembly of the cover 62. The holder 21 can thus only be removed up to the removal of the drawer 1 Cover 62 are moved, which serves as a stop and prevents the holder 21 can be removed upwards and disassembled. In Figure 5, the fastening device 20 is mounted on the pullout guide 8. As can be seen in the sectional view of FIG. 6, when the drawer is mounted, the teeth 25 on the holder 21 are in engagement with the teeth 52 on the guide 50. This makes possible a linear displacement of the holder 21 on the guide 50, however no lifting or lowering. In addition, the guide 50 is within the housing 30 to a certain extent pivotable about the bearing pin 56, so that a lateral adjustment of the holder 21 can be made. If the pullout guide 8 is in the extended position, the adjustment operations can be performed without tools by hand, since the screw 60 and the knurled nut 38 are accessible from the outside. This allows a comfortable adjustment of the position of the drawer. 1

As shown in FIG. 6, for a good guidance in the longitudinal direction, a web 24 standing vertically downwards is guided on the holder 21 in a groove 66 of the guide 50.

In Figure 8, the drawer 1 is shown during assembly, in which the projection 22 is inserted into the opening 7 on the rear wall 3. The drawer 1 is now pushed further back until the rear wall 3 shifts the holder 21 to the rear, as shown in FIG. As a result, the spring 28 is further tensioned until the desired end position is reached. For this purpose, the holder 21 can be moved to the rear wall 53 on the guide 50, but also a position of the rear wall 53 can serve as an end position. FIGS. 10 and 11 show a modified exemplary embodiment of a fastening device 120 for a pull-out guide 8, which serves to fix a drawer 1. In this and the following embodiments, the same reference numerals are used for the same components, so that only the modified components will be described in detail. The fastening device 120 comprises a holder 121 made of a bent metal sheet, which has a projection 122 directed towards the front, which can be inserted into an opening 7 in the rear wall 3 of the drawer 1. The holder 121 has a substantially C-shaped contour, wherein spaced from the upper projection 122, a web 123 is formed, which is slidably mounted on guide elements, in particular bolts 124. For this purpose, a guide in the form of elongated holes is formed on a guide 125, which may be made of a bent sheet metal, in which the bolts 124 engage the web 123. The guide 125 is fixed to the running rail 10 via fastening means 126, in particular welding points or adhesive dots. Further, a spring 127 is provided, which is stretched between the holder 121 and the guide 125, so that the holder 121 is biased in the opening direction. The holder 121 is only linearly displaceable, so that the other adjustment functions, such as the lateral adjustment and the height adjustment omitted. As a result, the fastening device 120 can be manufactured and assembled in a simple manner with only a few components.

For assembly, the drawer is moved with the rear wall 3 to the mounting device 120, to then insert the projection 122 in the opening 7 and the holder 121 to move against the force of the spring 127, as shown in Figure 1 1. After latching or fixing to further fastening means of the running rail 10, the drawer 1 is securely held, wherein about the holder 121, a length compensation can be made if necessary.

FIGS. 12 and 13 show an embodiment modified from the exemplary embodiment of FIGS. 10 and 11 in which the holder 121 is as described above, but a retaining device 70 is provided on the rear wall 3 of the drawer, by means of which a height adjustment of the drawer 1 in the back wall 3 can be made. The holding device 70 comprises a housing 71, which is fixed via a plurality of screws 72 on the rear wall 3. At a recess of the housing 71 a plurality of rod-shaped support elements 74 are stacked in a lamellar manner, the projection 122 being inserted into the stack of support elements 74 for fixation, so that the drawer is secured against being lifted off. On the housing 71, an adjusting mechanism is further provided with a rotatable wheel 76 which is rotatably mounted on the housing 71 and a support member 78 can move in height, for this example, a rack is provided. By turning the wheel 76, the height of the rear wall 3 can thus be adjusted relative to the running rail 10. After the desired height of the rear wall 3 is set by the wheel 76, the drawer 1 can be moved against the holder 121, so that the projection 122 between two support members 74 dips to fix the drawer 1 to the holding device 70. The support members 74 may be received within the housing 71 with ease, so as not to interfere with the immersion of the projection 122. As a result, the drawer 1 can be fixed to the rear wall 3 in the desired height position on the holding device 70. FIGS. 14 to 21 B show a further embodiment of a fastening device 80, which serves for fixing a drawer 1 to a running rail 10. The fastening device 80 comprises a displaceable holder 81 which can be inserted into an opening 7 on the rear wall 3 of the drawer 1 in order to fix it on opposite sides on a running rail 10. In Figure 15, the fastening device 80 is shown in the assembled position.

In FIGS. 16A and B, the fastening device without drawer 1 is shown, and it can be seen that the holder 81 has an opening-pointing projection 82 which can be inserted into the opening 7. The holder 81 is substantially C-shaped and comprises a lower web 83 which is slidably mounted on a holding web 100. The holding web 100 is fixed with a portion 101 on the running rail 10, for example by welding or gluing. An upwardly projecting pin 86 with a broadened head section is fixed to the retaining bar 100, which is a

Long hole 85 in the lower web 84 of the holder 81 passes through. As a result, the holder 81 is displaceably mounted on the holding web 100. Between the holding web 100 and the holder 81, a spring 94 is tensioned, which is designed as a tension spring and is held at one end to the support rail 100 fixed to the running rail 10 and on the opposite side to a projection of the holder 81.

The holder 81 can also be adjusted in a direction horizontal and perpendicular to the longitudinal direction of the track rail 10. This is on the lower jetty 83 an upper web 84 is provided, which rests on the web 83 in some areas and is also guided on the pin 86 and the retaining web 100 slidably and has a slot 85. In an area adjacent to the spring 94, an eccentric 87 is provided, by means of which the upper web 84 can be pivoted about the pin 86 relative to the lower web 83. The upper jetty

84 is held by a nose 90 which fixes the upper web 84 in the lateral direction. For this purpose, a slot-shaped recess 98 with a vertical portion 89 is provided on a vertical portion of the upper web 84 and the lower web 83, respectively, through which a tip of the nose 90 is guided. At the upper web 84 90 inwardly directed projections 88 are provided in the region of the nose, so that the upper web is not displaced in the lateral direction. If now the eccentric 87 adjusted, the upper web 84 can be held by the nose 90, while the lower web 83 is pivoted laterally with the holder 81.

Further, a height adjustment for the nose 90 is provided, which is formed integrally with a vertical plate 91. The vertical plate 91 is slidably held on a support plate 92, wherein the support plate 92 is fixedly connected to the running rail 10. The running rail 10 has on a side wall a recess 96 into which a web 97 of the support plate 92 engages. Furthermore, the support plate 92 engages around the outer contour of the running rail 10 so that the running rail 10 and support plate 92 form a solid unit. The support plate is preferably welded to the running rail 10. On the support plate 92 a plurality of vertical slots 95 are recessed, which are penetrated by pins 99 which are fixed to the plate 91. Further, an eccentric 93 is fixed to the plate 91, which is rotatably supported and upon rotation, the plate 91 moves in the vertical direction relative to the support plate 92, whereby the nose 90 is raised or lowered. Alternatively to the eccentric 93 and a flat-threaded spindle can be used.

The lateral adjustment is shown in FIGS. 17A and 17B in plan view and in FIGS. 18A and 18B in a rear view. In FIGS. 17A and 18A, the holder 81 is arranged with a gap A relative to the running rail 10. By turning the eccentric 87, the holder 81 pivots about the bolt 86 and the holder 81 with the lower web 83 is pivoted to the running rail 10, as shown in Figs. 17B and 18B. As a result, a corresponding orientation of the drawer 1 relative to the running rail 10 can be made. FIGS. 19A and 19B show the height adjustment of the fastening device 80. By turning the eccentric 93, the plate 91 is adjusted in height relative to the support plate 92, wherein the lowered position is shown in Figure 19A and the raised position in Figure 19B. By moving the vertical plate 91 relative to the support plate 92, the nose 90 is raised or lowered accordingly.

The situation is shown in FIGS. 20A and 20B, in which the holder 81 is prestressed against its front stop and the drawer has already been pushed onto the projection 82 by means of its opening 7. For this purpose, a section through the fastening device 80 is shown, in which the arrangement of the eccentric 87 in the region of the lower web 83 and the upper web 84 can be seen. In addition, it is shown in FIG. 20B that holding web 100 has an obliquely downwards angled section 103 which is inclined to the horizontal in an angle range between 2 ° and 20 °, in particular 5 ° to 10 °, and forms an inclined plane. As a result, when the lower web 83 is displaced in the horizontal direction of biasing, the holder 81 can be raised. The lower web 83 has a downwardly directed projection 102, which is lifted when moving along the section 103. By raising the holder 81, the projection 82 is raised in a height position approximately centrally to the opening 7 of the drawer. Since the drawer bottom 5 rests flush on the running rail 10, thus the optimum height of the projection 81 is centrally determined to the opening 7, whereby the sliding of the drawer is simplified to the projection 82.

In the figures 21 A and 21 B, a mounting position is shown in which the holder 81 has been moved by the drawer 1 to the rear, but not yet in the final position. As a result, the downwardly projecting protrusion 102 comes down over the obliquely oriented portion 103, so that the holder 81 is lowered to its normal position.

This lowering of the holder 81 during assembly can be used to set the drawer 1 almost free of play or clamping on the track. For this purpose, the lower web 83 and the holder 81 may be made in particular of spring steel. A virtually play-free or clamping setting the drawer on the track 10 is also achieved that when pushing backwards the drawer of the lower web 83 with a control surface 129 on a control cam 128 on the nose 90 meets, and the drawer together with the lower web 83 is pushed further to the rear. The control surface 129 thereby travels downwardly along the oblique control cam 128, which causes the rear end of the holder to be lowered downwards. The projection 82 pulls the drawer bottom against the upper edge of the nose 90th

The lower web 83 may in this case be made of spring steel, this allows by the elasticity tolerance compensation when clamping (in height) in conjunction with the backward sliding of the drawer. Of course, the adjusting mechanisms shown in the illustrated embodiments slots, pins, eccentric can be modified by the skilled person. Instead of an eccentric adjustment, a curve guide, a worm wheel or another component can be provided to make a corresponding adjustment. Of course, the linear guides can also be replaced by slots and sliders via slotted holes.

The mechanism for clamping the holder 81 on the rear wall 3 of the

Drawer can also be varied, the holder 81 is preferably moved obliquely downward during assembly of the drawer 3, to clamp the drawer 1 to the running rail 10.

For installation on a furniture body with two pullout guides on the side walls, a drawer is first placed on the rails and pushed in the direction of the rear wall. The drawer moves on the holder and thus couples the drawer to the running rail slidable in the longitudinal direction. Then drawer and holder are moved together in the coupled position to the final assembly position.

Before moving or moving, the drawer can change its position in height, taking the holder with it.

Furthermore, in the further course of the movement to the end position of the holder in its guide obliquely to the longitudinal direction and thereby the

Clamp the drawer to the running rail. LIST OF REFERENCE NUMBERS
