WO 2008/028809 PCT/EP2007/058733 Drawer The disclosure relates to a drawer having a drawer bottom, a front panel, and a rear wall opposite to the front panel, having two lateral panels, running in the displacement direction of the drawer 5 and implemented as hollow body sections, which are provided with adapters at least in the end areas, support retainers being fixed on the frontal adapters, which are connected by latching to the running rails. The drawer under discussion is used in a furniture body. The lateral panels form the lateral 0 delimitations in this drawer, the rear wall and the front panel being transverse to the lateral panels and perpendicular to the bottom. These drawers have proven themselves in various types of furniture, for example, in kitchen furniture, living room furniture, bedroom furniture, and the like. 5 Furniture of this type is also sold, inter alia, in the disassembled state in so-called cash and carry stores. The furniture is then assembled by the buyer himself. The furniture and/or the furniture components such as drawers and the like must be designed in consideration of these conditions. The frontal latches, i.e., the latches facing toward the front panel, between the support retainers 0 and the running rails are advantageous, because the assembly accordingly results on its own due to the constructive design of these latches. It may be required for catch means to have to be pressed for insertion of the drawer into the furniture body or for removal in various embodiments, so that the latching is disengaged. Catch 25 means, which are situated on both sides of the lateral panels of the drawer, typically have to be pressed. In addition, a tool may be necessary to disengage the latches, to reach into the intermediate space between the drawer and the furniture body. In addition, it may not be often recognizable to the user at which point the tool is to be applied and/or at which point the unlocking mechanism is situated. 30 3404017_1 (GHNatters) P80126AU WO 2008/028809 PCT/EP2007/058733 2 In particular upon the removal of a drawer, damage may easily result to the components guiding the drawer in the furniture body. In such a case, it would not be possible to insert the drawer back into the furniture body. 5 In an aspect there is provided a drawer having a drawer bottom , a front panel, and a rear wall opposite to the front panel, having two lateral panels, running in the displacement direction of the drawer and implemented as hollow body sections, which are provided with adapters at least in the end areas, support retainers being fixed on the frontal adapters, which are connected by latching to the running rails, wherein at least one or each frontal latch between the support 0 retainer and the running rail is formed by a coupling device and an elastic catch tongue engaging in an opening of the running rail and wherein the coupling device comprises a coupling outer part and a coupling inner part insertable therein. A solution having a simple design is achieved if the coupling device comprises a coupling outer part and a coupling inner part are engaged therein in the coupling position. 5 Each frontal latch between the support retainer and the running rail is formed by a coupling device and an elastic catch tongue engaging in an opening of the running rail. The coupling device comprises two coupling parts, which are engaged with one another in the 0 normal operating state for retracting and extending the drawer. However, if the drawer is to be removed from the furniture body, this is performed by force action on the coupling device upward in the vertical direction transverse to the extension direction, so that the two parts disengage, as will be explained in greater detail. Because the drawer is only fixed in one direction due to the mobility of at least one coupling part, the catch tongue is situated and 25 designed in such a way that it fixes the drawer in the direction running transversely to the fixing direction of the coupling device. Furthermore, the coupling devices and catch tongues are adapted to one another in such a way that the catch tongue comes out of the opening when the coupling device is decoupled. 30 The forces required to decouple the coupling devices may be applied in the most simple way for the first solution and/or a second suggestion if the drawer is the actuating element for each 3404017_1 (GHMatter) P80126AU WO 2008/028809 PCT/EP2007/058733 3 coupling device in such a way that a force acting perpendicularly or approximately perpendicularly to the running rail acts on each coupling device to remove the drawer from the furniture body. A relatively small force which acts on the drawer suffices due to the resulting lever arms. 5 The coupling and decoupling of each coupling device may thus be performed using moderate force application. In addition, the two coupling parts accordingly have a form-fit with one another in the coupled position. 0 In addition, the solution still has a simple design if each coupling outer part is inserted permanently in the end area of the running rail, and the coupling inner part is molded or applied on the support retainer fixed on the adapter. In the reversal of the above-mentioned solution, the coupling outer part is molded or applied on the support retainer fixed on the adapter, and the 5 coupling inner part is inserted in the end area of the running rail and protrudes in relation to the front face. It is especially advantageous if the coupling outer part has a hollow body section which may also still be elastically deformable. If the coupling outer part is inserted into the running rail, the coupling outer part is designed like 0 a plug. The coupling part inserted into the running rail is to be viewed as the fixed part, because the design of the coupling outer part and the coupling inner part is selected in such a way that when the drawer is raised, the coupling part molded or applied on the support retainer is moved in the extension direction, so that the drawer is also moved, so that the disconnection or the latching of the drawer with the running rail is disengaged, respectively. 25 The disconnection or the latching of the drawer from or to the running rail, respectively, is achieved in the simplest way by this design. The drawer is fixed in the vertical direction by the coupling device. However, in order that a 30 fixation is also provided in the extension direction, the catch tongue extending in the longitudinal direction of the running rail is molded onto each support retainer. This catch tongue is 3404017_1 (GHMatters) P80126AU WO 2008/028809 PCT/EP2007/058733 4 implemented as stepped on an end area, preferably on the end area facing toward the front panel of the drawer, and on the side facing away from the running rail in such a way that the end area rests on the guide rail in the engaged position and the step strikes against a stop, preferably against an edge of the adapter. A displacement of the drawer in relation to the running rail is thus 5 prevented. At a relatively small distance to the stepped end area of the catch tongue, it is provided with a catch lug, which engages in an opening of the running rail. In the latched state, the edge facing toward the step shape is at a slight distance to the edge delimiting the opening. If the drawer is 0 withdrawn from the furniture body by a least a width of the front panel, the drawer may be raised, by which the catch tongue is also deformed. Because the drawer is pressed still further out of the furniture body by being raised, the catch tongue is also still deformed by the stepped design in such a way that the catch lug comes free, i.e., it is withdrawn from the opening, so that the drawer may subsequently be removed from the furniture body. The insertion of the drawer is 5 accordingly performed exclusively by the insertion movement, the latching occurring automatically. In order that an elasticity of the hollow body section is provided, it has a guide slot extending in the longitudinal direction of the running rail, which is additionally used as a guide for the 0 coupling inner part engaging in the hollow body section. The guide slot expands in the direction toward the free end of the hollow body section. As will be described in greater detail, the coupling inner part is designed in such a way that the disconnection between the coupling outer part and the coupling inner part is possible without danger of damage. To allow this disconnection, the hollow body section of the coupling outer part is open on the free side facing 25 away from the running rail. In order that the coupling inner part may be positioned functionally correct in relation to the coupling outer part in the coupled position, the hollow body section of the coupling outer part is recessed stepped on the inside, the elevated area facing away from the open side of the hollow 30 body section to form a stop surface for the coupling inner part. In the coupled position, the coupling inner part strikes against this stop surface. 34040171 (GHMettemr) P80120 AU WO 2008/028809 PCT/EP2007/058733 5 Damping elements may advantageously be provided between faces of the coupling inner part and the coupling outer part opposite to one another. Thus, for example, a damping part may be provided on the coupling inner part or on the coupling outer part. It is also conceivable to situate 5 damping elements on the coupling inner part and the coupling outer part, the advantage of the damping elements being that impact noises are avoided or greatly reduced in the event of rapid opening of the drawer, which may be caused by the small distance required by the design between the catch lug on one side and the edge opposite to this catch lug, which delimits the opening in which the catch lug engages. 0 In order that the coupling inner part accordingly engages in a formfitting or terminating way in the hollow body section of the coupling outer part, the main cross-section of the hollow body section of the coupling outer part is designed like a rectangular tube, preferably like a square tube. In order that a free space is provided for the coupling inner part, at least the hollow body 5 section of the coupling outer part is equipped on the inside with forcing inclined faces. These forcing inclined faces are situated in relation to one another in such a way that upon raising of the drawer to decouple the running rail from the support part, the support part and thus the drawer are forced to move in the extension direction, the catch tongue simultaneously coming out of the opening, so that after being raised, the drawer may be removed from the furniture ,0 body. Accordingly, the coupling inner part and/or the support retainer perform a relative motion in relation to the fixed running rail during the raising of the drawer. Upon insertion of the drawer into the furniture body, the catch tongue engages in the opening at the end of the movement, so that the running rail is synchronously carried along upon retraction and extension of the drawer. Upon insertion, the drawer slides on the running rails, the rear end being automatically fixed. 25 The drawer is additionally fixed in a way explained in greater detail in the area of the rear wall, these elements being designed so that upon the disconnection of the drawer from the running rails, these components are not damaged. For simple fixing of the coupling outer part in the inner chamber of the guide rail, this plug 30 shaped coupling outer part is provided with an insertion pin inserted into the running rail, which has a transverse hole for a safety screw. 3404017_1 (GHattem) P80126AU WO 2008/028809 PCT/EP2007/058733 6 In order that the connection between the drawer and the running rail is always secured in normal operation and the connection may be easily disengaged to remove the drawer from the furniture body, the coupling inner part is designed like a T-slot nut, and is recessed stepped multiple times 5 viewed in the longitudinal direction of the running rail. In preferred embodiments, the coupling inner part shaped like a T-slot nut comprises two end steps and a middle step. The end part facing toward or away from the support retainer is used as a guide inside the hollow body section, and the opposing end part and/or the opposing end step is designed in such a way that it engages in the guide slot of the hollow body section. The middle part is designed in such a way 0 that the connection may be disengaged without the danger existing that the hollow body section will be damaged upon the disconnection. In order that the disconnection between the coupling outer part and the inner part is facilitated, it is also provided that the middle part and/or the middle step of the coupling inner part is designed 5 as wedge-shaped, the tip facing away from the opening of the hollow body section of the coupling outer part. In a preferred embodiment, the angles of inclination correspond to the angles of inclination of the guide slot of the coupling outer part. As already noted, the hollow profile section of the coupling outer part is provided with internal ,0 forcing inclined faces, which may extend over the entire depth or over an area facing toward the open side of the hollow profile section. In every embodiment, they are designed in such a way that when the drawer is raised, they are automatically shifted in the extension direction. In all embodiments, these forcing inclined faces of the coupling outer part are functionally assigned to the guide slot. If this guide slot is on the side facing toward the support retainer, the forcing 25 inclined faces increase the distance to the opposite wall of the hollow body section. If the guide slot is on the side facing away from the support retainer, the distance to the opposite wall of the hollow body section decreases in the direction toward the open side. In this case, the coupling inner part is equipped with diagonal faces corresponding to the forcing inclined faces. 30 3404017_1 (GHMatter) POO128AU WO 2008/028809 PCT/EP2007/058733 7 As already noted, the drawer is fixed at the rear end, so that a tilting movement is avoided upon retraction and extension. In the simplest embodiment, it is secured in the area of the rear wall by hooks situated on the running rails. These hooks are preferably designed as C-shaped in such a way that they are not damaged upon removal of the drawer from the furniture body or upon 5 insertion. The pockets formed by the hooks are open in the direction toward the front panel of the drawer. Accordingly, these hooks run in the longitudinal direction of the running rails. The invention is explained in greater detail on the basis of the appended drawings. 0 In the figures: Figure I shows a drawer according to the invention having removed front panel in a perspective illustration looking toward the front side 5 Figure 2 shows the running rail having the support retainer in a perspective illustration in a disconnected state, the coupling outer part being inserted into the running rail, however Figure 3 shows an illustration corresponding to Figure 2, in which the coupling inner part is inserted into the coupling outer part, however Figure 4 shows the running rail with the support part in the latched state Figure 5 shows an illustration corresponding to Figure 4, but in an enlarged illustration 25 Figure 6 shows an illustration corresponding to Figure 4, but showing the first step of the disconnection of the support retainer from the running rail Figure 7 shows an illustration corresponding to Figure 6, but in an enlarged illustration 30 3404017_1 (GHMtter) P80126AU WO 2008/028809 PCT/EP2007/058733 8 Figure 8 shows an illustration corresponding to Figure 4, but showing the unlatched position Figure 9 shows an illustration corresponding to Figure 8, but in an enlarged illustration 5 Figure 10 shows the running rail with the latched support retainer in a sectional illustration Figures II and 12 show illustrations corresponding to Figures 2 and 3, in which the coupling device 0 is designed in a mirror-image configuration, however Figure 13 shows a detail XIII according to Figure 10 in an enlarged illustration, showing the spring tongues in the latched state, and 5 Figure 14 shows a sectional illustration of the forward end area of a running rail with latched support retainer according to a further exemplary embodiment of the invention. For reasons of illustration of the idea on which the invention is based, the front panel of the 0 drawer 10 is not shown in Figure 1. The drawer 10 comprises the bottom 11, the two lateral panels 12, 13, and the rear wall 15. As is clearly shown in Figure 1, the lateral panels 12, 13 comprise hollow body sections and the bottom I I is connected fixed thereto. As explained in greater detail on the basis of Figures 4 through 10, the panels and/or the drawer are/is detachably connected to running rails 23. The running rails follow the extension and retraction movement of 25 the drawer 10. The running rails 23 are coupled (not shown) to two lateral extension guides, at least one further guide rail being situated fixed on the furniture body. An adapter is inserted into the interior of each lateral panel 12, 13. The adapter carries a support retainer, in which front panel retainers are inserted, preferably inserted by latching, which are 30 fastened on the front panel. The connection between the support retainers 14 and the running 3404017_1 (GHMaIes) P50120 AU WO 2008/028809 PCT/EP2007/058733 9 rails is performed in each case by a coupling device 17, which is shown in greater detail in Figures 2 and 3. Figure 2 shows that the support retainer 14 is inserted in the adapter 16. The front panel retainer 5 is equipped with two alignment screws 18 for orienting the front panel. The coupling device 17 comprises a coupling outer part 19 and a coupling inner part 20. In the embodiment according to Figure 2, the coupling outer part 19 is equipped with an insertion pin 21 (Figure 10), which is inserted and secured in the end area of the running rail. 0 The coupling outer part 19 has a hollow body section 24, protruding in relation to the front face of the running rail 23, which is a rectangular tube in the main cross-section in the exemplary embodiment shown. As shown in Figure 2 in particular, the lower face of the hollow body section 24 is recessed stepped, so that a stop face 25 for the coupling inner part 20 is formed. The coupling outer part 19 is additionally provided on the top side with a guide slot 26, which 5 expands toward the opening of the hollow body section 24. As Figure 2 also shows, the guide rail 23 is provided on the top side with a rectangular opening 27, in which an elastic catch tongue 28 of the support retainer 14 engages. The drawer 10 is thus fixed and/or secured in the withdrawal direction and in the insertion direction. As will be explained, in the latched state, the drawer 10 is secured in the vertical direction by the coupling device 17. *0 The coupling inner part 20 forms a one-piece plastic molded part with the support retainer 14 in the embodiment according to Figures 2 and 3. The coupling inner part 20 extends approximately over the height of the bottom 11. The coupling inner part 20 is also implemented as stepped, in the exemplary embodiment shown, the coupling inner part 20 comprises two end parts 29, 30 25 and a middle part 31. The upper end part 30 facing toward the support retainer 14 has the smallest distance to the two webs delimiting the guide slot 26, so that it may be viewed as a guide element. The end part 29 facing away from the support retainer 14 has a width which corresponds to the width of the inner chamber of the hollow body section 24, so that this end part may also be viewed as a guide element. The face of the end part 29 facing toward the guide rail 30 23 presses against the stop face 25 when the coupling inner part 20 is inserted into the coupling outer part 19, with the catch tongue clipping in shortly before reaching the final position. As 3404017_1 (GHMttemrs)P80126AU WO 2008/028809 PCT/EP2007/058733 10 Figure 2 also shows, the middle part 31 is implemented as wedge-shaped, the tip facing toward the guide rail 23. The angles of inclination correspond or approximately correspond to the angle of inclination of the guide slot 26. 5 Figure 3 shows the connection of the drawer 10 to the running rail 23 via the coupling device 19. The figure shows that the end part 30 facing toward the support retainer 14 engages in the guide slot 26 and the opposing end part 29 and the middle part 31 lie inside the inner chamber of the hollow body section 24. The outer free front faces of the hollow body section 24 and the coupling inner part 20 are aligned with one another. 0 Figures 4 through 10 show that the end of the running rail 23 assigned to the rear wall 15 is also equipped with an adapter 32. In contrast to the embodiment shown, one or more adapters may be situated between the forward and rear areas. Figure 2 additionally also shows that the guide slot 26 is delimited by positioning webs, which lie on the interior and are implemented on the open 5 side as the diagonal faces 33. Figures 4 through 9 show that a hook 34 is provided in the rear and area of the running rail 23 to lock the drawer 10. In the exemplary embodiment shown, the hook 34 is C-shaped. 0 Figures 4 through 9 additionally show that each support retainer 14 is equipped with an elastic catch tongue 28, which engages using a lug in the opening 27 in the latched state. The catch tongue 28 is designed in such a way that the drawer 10 is not displaceable in relation to the running rail 23 in the extension direction when the drawer 10 is latched. The locking is performed in the other direction by the coupling devices 17. 25 Figures 4 and 5 show the drawer 10 in the latched state with the running rail 23. Figures 6 and 7 show the drawer 10 in an intermediate position for removing the drawer 10 from the furniture body. In this position, the drawer 10 is pulled out of the furniture body by at least the thickness of the front panel. The drawer is moved slightly upward in relation to the running rail by an 30 appropriate manually applied force, the areas of the hollow body section 24 adjoining the guide slot 26 deforming in particular. In addition, the catch tongue 28 has already been withdrawn 3404017_1 (GH1.tterm) PB0126AU WO 2008/028809 PCT/EP2007/058733 11 from the opening 27, so that by further withdrawal of the drawer 10 from the furniture body and further deformation of the hollow body section 24, the drawer 10 disengages from the running rail 23 and/or disengages from the two lateral running rails 23, so that the drawer is freed, as will be explained on the basis of Figure 13. The pocket delimited by the hook 34 is open toward the 5 front panel, so that the withdrawal of the drawer 10 is not obstructed. The insertion of the drawer 10 into the furniture body is performed by placing it on the running rails 23 and pushing in. 0 Figure 10 shows the running rails having the adapters 16 and 32 in a sectional illustration, as well as the frontal support retainer 14. It is accordingly clear that the insertion pin 21 of the coupling outer part 19 is inserted into the running rail 23 to terminate it and is secured by suitable measures. In addition, this figure shows how the drawer 10 is secured in the rear area by the hook 34, and the catch tongue 28 engages to lock in the opening 27. 5 Figures I I and 12 show illustrations corresponding to Figures 2 and 3, the coupling outer part 19 being assigned to the support retainer 14 and the coupling inner part 20 accordingly being assigned to the running rail 23, however. As Figure I I shows, the coupling outer part is provided with the forcing inclined faces 33, which are in turn assigned to the guide slot 26, which is now 0 on the bottom. The distance to the opposite wall is also decreased. In addition, Figure I I shows that the coupling inner part 20 is provided with corresponding diagonal faces 36. The opposing web may be dispensed with, because the lateral guiding inside the coupling outer part 19 is provided by the wedge-shaped design of the end part 29. 25 Figures 4 and 5 show the drawer 10 connected to the running rails 23. The coupling inner part 20 strikes against the stop face 25 of the coupling outer part 19. The narrower end part 30 is guided in the guide slot 26. The lug of the catch tongue 28 engages in the opening 27. The panels 12, 13 are pushed under the C-shaped hooks 34 situated in the rear area. The hooks 34 are designed in such a way that the panels 12, 13 do not touch the hooks 34 in the insertion direction. 30 34040171 (GHMtter) P80126AU WO 2008/028809 PCT/EP2007/058733 12 Figures 6 and 7 show the first step of the removal of the drawer 10 from the furniture body. The hollow body section 24 is elastically expanded by the middle part 30 of the coupling inner part 20 by an upwardly directed vertical force by raising the drawer 10. The lower end part 29 is in contact with the restrictive faces 33, so that the drawer 10 is additionally moved in the 5 withdrawal direction in relation to the running rail 23. The catch lug 37 of the elastic catch tongue 28 has been withdrawn from the opening 27, and has the freely oscillating end resting on the removal edge of the drawer, so that jamming, hooking, or damage of the catch tongue 28 may be prevented. It is advantageous in the solution described above that the drawer 10 is secured, against jamming, for example. Furthermore, the short removal path is very advantageous. 0 Figures 8 and 9 show the next step for removing the drawer 10 from the furniture body. Each part of each panel 12, 13 assigned to the rear wall 15 has been withdrawn from the area of the hook 34. The drawer 10 may now be withdrawn completely from the furniture body. The rear area of the drawer 10 slides on the running rails 23, so that damage to the hooks 34 upon the 5 removal from the furniture body and upon insertion into the furniture body is effectively avoided. Figure 13 shows an enlarged illustration of a detail from the support retainer 13 in connection with the running rail 23. Accordingly, a catch lug 37, which engages completely in the opening 0 27 in the latched position shown, is molded onto the elastic catch tongue 28 on the side directed toward the central longitudinal axis of the running rail 23. The elastic catch tongue 28 is recessed stepped on an end area, preferably on the end area facing toward the front panel, this area resting on the running rail. The edge formed by the stepped design lies in front of a lifting edge of a metallic adapter. As Figure 13 clearly shows, the edge of the catch lug 37 assigned to the stepped 25 end area is at a relatively small distance from the edge delimiting the opening. It may be seen from Figure 13 that upon raising of the drawer 10, the spring tongue 28 having the stepped end area is moved upward. Because the coupling device 17 of the drawer 10 is automatically displaced in the withdrawal direction upon raising of the drawer 10 by the design 30 already described, the stepped end area is sufficiently deformed that the catch lug 37 comes out of the opening 27, so that the drawer 10 may then be removed from the furniture body, the 3404017_1 (GHNattom) P80126AU WO 2008/028809 PCT/EP2007/058733 13 running rail 23 remaining fixed. Furthermore, it results from Figure 13 that upon insertion of the drawer into the furniture body, the catch tongue 28 moves back into the position shown as soon as the catch lug 37 comes into the area of the opening 27. The distance of the frontal edge of the catch lug 17 to the edge of the running rail 23 facing toward it, which delimits the opening 27, is 5 necessary so that the unlocking may occur. Figure 14 shows that a damping element 38, made of an elastic plastic or in the form of a spring or the like, for example, is attached on the coupling outer part 19. This damping element 38 is opposite to a contact face of the coupling inner part 20. 0 Impact noises which could occur upon rapid opening of the drawer may be prevented or decreased so much by this damping element 38 that they are hardly still perceived as annoying. Of course, it is also possible to attach a damping element 38 to the coupling inner part 20 or 5 alternatively thereto - to both coupling parts 19 and 20. The invention is not restricted to the exemplary embodiment shown. It is essential that a plug and/or the coupling outer part 19 is inserted into each running rail 23 on the side facing toward the front panel, which has a hollow body section 24, in whose interior the coupling inner part 20 0 is inserted in the latched state, and this hollow body section 24 may be disconnected without damage from the coupling outer part 19 by forces acting on the drawer through the coupling inner part 20 to remove the drawer 10. In the claims which follow and in the preceding description of the invention, except where the 25 context requires otherwise due to express language or necessary implication, the word "comprise" or variations such as "comprises" or "comprising" is used in an inclusive sense, i.e. to specify the presence of the stated features but not to preclude the presence or addition of further features in various embodiments of the invention. 3404017_1 (GHMatters) P80126 AU WO 2008/028809 PCT/EP2007/058733 14 It is to be understood that, if any prior art publication is referred to herein, such reference does not constitute an admission that the publication forms a part of the common general knowledge in the art, in Australia or any other country. 3404017_1 (GHMIaTter) P80126AU
