Description

drawer

The invention relates to a drawer with a drawer bottom, a front panel and the front panel opposite rear wall, with two extending in the direction of the drawer, designed as a hollow body sections side frames, which are provided at least in the end with adapters, wherein at the front adapters carrier holder are fixed, which are connected by latching with the rails.

The drawer in question is used in a furniture body. The side frames in these drawers form the lateral boundaries, with the rear wall and the front panel are transverse to the side frames and perpendicular to the ground. These drawers have been proven in the different types of furniture, for example, kitchen furniture, living room furniture, bedroom furniture and the like.

Such furniture is sold, inter alia, in the disassembled state in so-called driving markets. The furniture is usually then assembled by the buyer himself. The furniture or the furniture components such as drawers and the like must be designed taking these circumstances into account.

The front-side, i. the front panel facing latching between the support brackets and the rails are advantageous because the assembly results in accordance with the self-evident by the structural design of these locks.

The latches are known in various designs. In these previously known embodiments, however, it is necessary for the insertion of the drawer into the furniture body or for removal in various designs

Locking means must be pressed so that the lock is released. Usually then locking means must be pressed, which are arranged on both sides of the side frames of the drawer. To release the locking beyond a tool is still required to be in the space between the Drawer and the furniture body to arrive. In addition, it is often not recognizable to the user at which point the tool is to be set or at which point the unlocking mechanism is arranged.

In particular, when removing a drawer, it can easily damage the drawer in the furniture body leading components. In such a case, it would not be possible to insert the drawer back into the furniture body.

The invention has for its object to make a drawer of the type described in more detail so that at least for the removal of the drawer from the furniture body to solve the latches no tools, such as. Tools are necessary, it should be ensured that the retraction and extension of the drawer can be done in the usual way.

The stated object is achieved by a first proposal by each front-side latching between the carrier holder and the running rail of a coupling device and an engaging in an opening of the running rail, resilient detent tongue is formed.

The coupling device consists of two coupling parts, which are in the normal operating state for retracting and extending the drawer engaged with each other. However, if the drawer is to be removed from the furniture body, this is done by applying force to the coupling device, transversely to the pull-out direction in the vertical upward direction, so that the two parts are disengaged, as will be explained in more detail. Since the mobility of at least one coupling part of the drawer is fixed only in one direction, the latching tongue is arranged and designed so that it fixes the drawer in the direction transverse to the fixing direction of the coupling device direction. Further, the coupling devices and latching tongues are coordinated so that the latching tongue comes out of the opening when the coupling device is decoupled. The forces required to disengage the coupling devices can be applied for the first solution and / or a second proposal in the simplest manner, when the drawer is the actuating element for each coupling device such that to remove the drawer from the furniture body on each coupling device is a vertical or acting approximately perpendicular to the running rail force acts. Due to the resulting lever arms, a relatively small force is sufficient, which acts on the drawer.

A structurally simple solution is achieved when the coupling device consists of a coupling outer part and an engageable in the coupling position inside clutch. This can be done with a moderate effort the engagement and disengagement of each coupling device. In addition, the two coupling parts in the engaged position mutatis mutandis form-fitting to each other.

The solution also becomes structurally simple if each coupling outer part is firmly inserted into the end region of the running rail, and the coupling inner part is formed or attached to the carrier holder fixed to the adapter. In the reverse of the aforementioned solution, it is provided that the coupling outer part is molded or attached to the carrier holder fixed to the adapter, and that the coupling inner part is inserted into the end region of the running rail and projects with respect to the end face. It is particularly advantageous if the coupling outer part has a hollow body portion, which may also be elastically deformable.

If the coupling outer part is inserted into the running rail, the coupling outer part is designed in the manner of a plug. The inserted into the running rail coupling part is to be regarded as the fixed part, since the design of the outer coupling part and the clutch inner part is chosen so that when lifting the

Drawer that is molded on the support holder or scheduled coupling part is moved in the extension direction, so that the drawer is moved so that the separation or the locking of the drawer is solved with the running rail. By this design, the separation or the Verras- tion of the drawer is achieved by the running rail in the simplest way.

By the coupling device, the drawer is fixed in the vertical direction. However, so that a fixation in the extension direction is given, it is provided that the support tongue extending in the longitudinal direction of the running rail is integrally formed on each support holder. This latching tongue is formed stepwise at an end region, preferably at the end region facing the front panel of the drawer, and at the side facing away from the running rail such that in the latched position the end region rests on the guide rail and the step against a stop, preferably against an edge of Adapter beats. As a result, a displacement of the drawer relative to the running rail is prevented.

At a relatively small distance from the step-shaped end region of the latching tongue, it is provided with a latching nose which engages in an opening in the running rail. In the latched state, the edge shape facing edge is at a small distance to the edge bounding the opening. If the drawer is pulled out of the furniture body by at least one width of the front panel, the drawer can be raised, as a result of which the latching tongue is also deformed. As is pushed further by the lifting of the drawer from the furniture body, and the latching tongue is still deformed by the step-shaped design so that the latch comes free, i. It is pulled out of the opening so that the drawer can then be removed from the furniture body. The insertion of the drawer takes place analogously exclusively by the insertion movement, wherein the locking takes place automatically.

So that an elasticity of the hollow body portion is given, it is provided that this has a guide slot extending in the longitudinal direction of the running rail, which also serves as a guide for engaging in the hollow body portion clutch inner part. The guide slot widens in the direction of the free end of the hollow body portion. As will be described in more detail, the clutch inner part is designed so that the separation between the clutch outer ßenteil and the clutch inner part without risk of damage is possible. To enable this separation, it is provided that the hollow body portion of the coupling outer part is open at the free side facing away from the running rail.

So that the clutch inner part can be positioned functionally in the engaged position relative to the clutch outer part, it is provided that the hollow body portion of the clutch outer part is stepped stepped inside, wherein the raised portion of the open side of the Hohlkörperabschnit- tes to form a stop surface facing away for the clutch inner part.

In the engaged position, the clutch inner part beats against this stop surface.

Advantageously, damping elements can be provided between opposing surfaces of the clutch inner part and the clutch outer part. Thus, e.g. a damping part on the clutch inner part or on the clutch outer part are provided. It is also conceivable to arrange damping elements on the clutch inner part and the clutch outer part, wherein the advantage of the damping elements lies in avoiding or greatly reducing impact noise when the drawer is opened quickly, which may be due to the constructively necessary small distance between the latching lug on the one hand and the opposite edge of this latch, which limits the opening into which engages the latch.

Thus, the clutch inner part mutatis mutandis form-fitting or closing in the

Hollow body portion of the clutch outer part engages, it is provided that the basic cross section of the hollow body portion of the coupling outer part is designed in the manner of a square tube, preferably in the manner of a square tube. Thus, a clearance for the clutch inner is created, it is provided that at least the hollow body portion of the clutch outer part with the inside

Zwangsführungsschrägflächen is equipped. These positive guide oblique surfaces are arranged relative to one another in such a way that when the drawer is lifted for decoupling the running rail with the carrier part, the carrier part and thus the drawer are inevitably moved in the extension direction, at the same time the latching tongue comes out of the opening, so that can be removed from the furniture body after lifting the drawer. Consequently, during the lifting of the drawer, the clutch inner part or the carrier holder performs a relative movement to the stationary running rail. When inserting the drawer into the furniture body snapped at the end of the movement

Locking tongue in the opening, so that then the retainer is taken synchronously when retracting and extending the drawer. When inserting the drawer slides on the rails, the rear end is automatically fixed. The drawer is also fixed in the area of the rear wall in a more detailed manner, wherein these elements are designed so that these components are not damaged in the separation of the drawer of the rails.

For easy fixing of the coupling outer part in the interior of the guide rail is provided that this plug-shaped coupling outer part is provided with an inserted into the running rail Einsteckzapfen having a transverse bore for a locking screw.

Thus, the connection between the drawer and the running rail is always secured in normal operation and to remove the drawer from the

Furniture carcass the connection can be solved easily, it is provided that the clutch inner part is designed in the manner of a sliding block and seen in the longitudinal direction of the running rail, is stepped down several steps. In preferred embodiments, it is provided that the slot-shaped clutch inner part consists of two output stages and one intermediate stage. It is envisaged that the

Carrier holder facing or remote end piece serves as a guide within the hollow body portion, and that the opposite end piece or the opposite end stage is designed so that it engages in the guide slot of the hollow body portion. The middle piece is designed such that the connection can be released without the risk of damaging the hollow body portion during the separation.

So that the separation between the clutch outer part and the inner part is favored, it is also envisaged that the middle piece or the middle stage of the Clutch inner part is designed wedge-shaped, wherein the tip of the opening of the hollow body portion of the clutch outer part is remote. In a preferred embodiment, the angles of inclination correspond to the helix angles of the guide slot of the clutch outer part.

As already stated, the hollow profile section of the coupling outer part is provided with inner positive guide oblique surfaces which can extend over the entire depth or over an area which faces the open side of the hollow profile section. With each version, they are designed in such a way that when the drawer is raised, it is inevitably moved in its extension direction in the extension direction. In all versions, these positive guide inclined surfaces of the clutch outer part are assigned to the guide slot functionally. If this guide slot lies on the side facing the carrier holder, the positive guide oblique surfaces increase the distance to the opposite wall of the hollow body section.

If the guide slot lies on the side facing away from the carrier holder, the distance to the opposite wall of the hollow body section decreases in the direction of the open side. In this case, the clutch inner part is equipped with corresponding to the positive guide inclined surfaces inclined surfaces.

As already mentioned, the drawer is fixed at the rear end, so that a tilting movement during extension and retraction is avoided. In the simplest version, it is provided that it is secured in the region of the rear wall by hooks arranged on the rails. These hooks are preferably C-shaped so that they are not damaged when removing the drawer from the furniture body or when inserting. The pockets formed by the hooks are open towards the front panel of the drawer. As a result, these hooks extend in the longitudinal direction of the rails.

With reference to the accompanying drawings, the invention will be explained in more detail.

Figure 14 is a sectional view of the front end portion of a track with locked carrier holder according to another embodiment of the invention.

For reasons of illustration of the concept underlying the invention, the front panel of the drawer 10 is not shown in FIG. The drawer 10 consists of the bottom 11, the two side frames 12, 13 and the rear wall 15. As the figure 1 clearly shows, the side frames 12, 13 of hollow body sections and the bottom 11 is firmly connected thereto. As will be explained with reference to Figures 4 to 10, the frames or the drawer with rails 23 are detachably connected. They follow the retraction and extension movement of the drawer 10. The rails 23 are coupled in a manner not shown with two lateral pull-out guides, wherein at least one further guide rail is fixedly arranged on the furniture body.

In the interior of each side frame 12, 13, an adapter is inserted. The adapter carries a carrier holder inserted into the front panel holder, preferably latching inserted, which are attached to the front panel. The connection between the carrier holders 14 and the rails is carried out by a respective coupling device 17, which is shown in more detail in Figures 2 and 3.

FIG. 2 shows that the carrier holder 14 is inserted into the adapter 16. The front panel holder for aligning the front panel is equipped with two adjustment screws 18. The coupling device 17 consists of a clutch outer part 19 and a clutch inner part 20. In the embodiment of Figure 2, the clutch outer part 19 is provided with a Einsteckzapfen 21 (Figure 10), which is inserted and secured in the end region of the track rail.

The coupling outer part 19 has a hollow body section 24 projecting in relation to the end face of the running rail 23, which in the exemplary embodiment illustrated. play in the basic cross-section is a square tube. As FIG. 2 shows in particular, the lower surface of the hollow body section 24 is stepped, so that a stop surface 25 is formed for the inner coupling part 20. The clutch outer 19 is also provided on the upper side with a guide slot 26 which widens to the opening of the hollow body portion 24. As the

Figure 2 also shows, the guide rail 23 is provided on the upper side with a square opening 27 into which a resilient latching tongue 28 of the support holder 14 engages. As a result, the drawer 10 is fixed or secured in the pull-out 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.

The clutch inner 20 forms in the embodiment of Figures 2 and 3 with the carrier holder 14 is a one-piece plastic molding. The clutch inner part 20 extends approximately over the height of the bottom 11. The clutch inner part

20 is further stepped, in the illustrated embodiment, the coupling inner part 20 consists of two end pieces 29, 30 and a central part 31. The upper, the support holder 14 facing end piece 30 has a smallest distance between the two guide slot 26 limiting webs, so that it Guide element can be considered. That the carrier holder 14 facing away from tail 29 has a width which corresponds to the width of the interior of the hollow body portion 24, so that this tail can be regarded as a guide element. The guide rail 23 facing the surface of the end piece 29 abuts against the stop surface 25 when the clutch inner 20 is inserted into the clutch outer 19, wherein shortly before reaching the end position einklippst the latching tongue. As the figure 2 also shows, the middle part 31 is wedge-shaped, wherein the tip of the guide rail 23 is facing. The helix angles coincide or approximately match the helix angles of the guide slot 26.

FIG. 3 shows the connection of the drawer 10 to the running rail 23 via the coupling device 19. The FIGURE shows that the end piece 30 facing the carrier holder 14 engages in the guide slot 26 and that the opposite end piece 29 and the middle part 31 are inside the interior of the hollow - köφerabschnittes 24 is located. The outer free end faces of the hollow body portion 24 and the clutch inner part 20 are aligned with each other.

FIGS. 4 to 10 show that also the end of the rear wall 15 associated with the

Running rail 23 is equipped with an adapter 32. In contrast to the illustrated embodiment, one or more adapters may be disposed between the front and rear portions. FIG. 2 additionally shows that the guide slot 26 is bounded by positioning steps which lie on the inside and are formed as inclined surfaces 33 on the open side.

FIGS. 4 to 9 show that a hook 34 is provided in the rear end region of the running rail 23 in order to lock the drawer 10. In the illustrated embodiment, the hook 34 is C-shaped.

Figures 4 to 9 also show that each carrier holder 14 is equipped with a resilient latching tongue 28 which engages in the latched state with a nose in the opening 27. The latching tongue 28 is designed so that the drawer 10 relative to the running rail 23 in the extension direction is not displaced when the drawer 10 is locked. The locking in the other direction is effected by the coupling devices 17th

Figures 4 and 5 show the drawer 10 in the locked state with the running rail 23. Figures 6 and 7 show the drawer 10 in an intermediate position for removal of the drawer 10 from the furniture body. In this

Position is the drawer 10 at least the thickness of the front panel pulled out of the furniture body. In this case, the drawer is moved a little bit by a corresponding manually applied force relative to the running rail upwards, in particular deforming the adjacent to the guide slot 26 areas of the hollow body portion 24. In addition, the latching tongue 28 is already pulled out of the opening 27, so that by further pulling out of the drawer 10 from the furniture body and further deformation of the hollow body portion 24 of the drawer 10 is disengaged from the running rail 23 and out of engagement with the two lateral rails 23rd comes, so that the drawer is free, as will be explained with reference to FIG 13. The limited by the hook 34 bag is open to the front panel, so that the pulling out of the drawer 10 is not hindered.

The insertion of the drawer 10 in the furniture body is done by placing on the rails 23 and insertion.

FIG. 10 shows the running rail with the adapters 16 and 32 in a sectional view as well as the front carrier holder 14. It then becomes clear that the insertion pin 21 of the clutch outer part 19 is inserted into the running rail 23 and secured by suitable measures. In addition, this figure shows how is secured by the hook 34 of the drawer 10 in the rear region, and that the latching tongue 28 engages lockingly into the opening 27.

FIGS. 11 and 12 show illustrations corresponding to FIGS. 2 and 3, but with the coupling outer part 19 on the carrier holder 14 and the clutch inner part 20 consequently being associated with the running rail 23. As FIG. 11 shows, the outer coupling part is provided with the positive guide oblique surfaces 33, which in turn are assigned to the now underlying guide slot 26. This also reduces the distance to the opposite

Wall. In addition, Figure 11 shows that the clutch inner part 20 is provided with corresponding inclined surfaces 36. The opposite web can be omitted since the lateral guidance within the clutch outer part 19 is given by the wedge-shaped design of the end piece 29.

FIGS. 4 and 5 show the drawer 10 connected to the rails 23. The inner coupling part 20 strikes against the abutment surface 25 of the outer coupling part 19. The narrower end piece 30 is guided in the guide slot 26. The nose of the latching tongue 28 engages in the opening 27. The frames 12, 13 are pushed under the arranged in the rear region C-shaped hook 34. The hooks 34 are designed so that the frames 12, 13 do not touch the hooks 34 in the direction of insertion. Figures 6 and 7 show the first step of removing the drawer 10 from the furniture body. By an upward vertical force by lifting the drawer 10, the hollow body portion 24 is elastically expanded by the central part 30 of the clutch inner part 20. The lower end piece 29 is in contact with the positive guide surfaces 33, so that the drawer 10 is additionally moved in the extension direction relative to the running rail 23. The locking lug 37 of the resilient latching tongue 28 has been pulled out of the opening 27, and lies with the free-swinging end on the Aushebekante of the drawer, so that jamming, snagging or damage to the latching tongue 28 can be excluded. It is advantageous by the solution described above, that the drawer 10 is secured, for example against jamming. Furthermore, the short Aushebeweg is very beneficial.

FIGS. 8 and 9 show the next step for removing the drawer 10 from the furniture body. Thereafter, each of the rear wall 15 associated part of each frame 12, 13 has been pulled out of the region of the hook 34. The drawer 10 can then be completely pulled out of the furniture body. The drawer 10 slides with the rear area on the rails 23, so that damage to the hook 34 is effectively avoided when removing it from the furniture body and when inserting into the furniture body.

13 shows an enlarged view of a section of the carrier holder 13 in connection with the running rail 23. Thereafter, a latching lug 37 is integrally formed on the resilient latching tongue 28 on the directed towards the central longitudinal axis of the running rail 23 side, in the illustrated latched position fully into the Opening 27 engages. The resilient latching tongue 28 is stepped at an end region, preferably at the end region facing the front panel, this area resting on the running rail. The edge formed by the step-shaped design lies in front of a lifting edge of the metallic adapter. As FIG. 13 clearly shows, the edge of the latching lug 37 assigned to the step-shaped end region is at a relatively small distance from the edge delimiting the opening. From FIG. 13 it follows that when the drawer 10 is lifted, the spring tongue 28 is moved upwards with the step-shaped end region. Since when the drawer 10 is lifted by the already described design of the coupling device 17 of the drawer 10 inevitably moved in the extension direction and the running rail 23 is fixed, the stepped end portion is deformed so far that the locking lug 37 comes out of the opening 27, so that then the drawer 10 can be removed from the furniture body, wherein the running rail 23 is fixed. It also follows from the figure 13 that when inserting the drawer into the furniture body, the latching tongue 28 moves back into the position shown, as soon as the locking lug 37 in the area of

Opening 27 is coming. The distance between the front edge of the locking lug 17 to the facing edge of the running rail 23, which limits the opening 27, is necessary so that the unlocking can take place.

In Figure 14 it is shown that the coupling outer part 19, a damping element 38, for example, made of an elastic plastic or in the form of a spring or the like, is attached. This damping element 38 is opposite to a contact surface of the clutch inner part 20.

By means of this damping element 38, impact noises which could arise during rapid opening of the drawer can be prevented or reduced so much that they are hardly perceived as disturbing.

It is of course also possible, a damping element 38 on the clutch inner part 20 or - alternatively - on both coupling parts 19 and

20 to install.

The invention is not limited to the illustrated embodiment. It is essential that in each rail 23 on the front panel facing side, a plug or the coupling outer part 19 is used, which has a hollow body portion 24, in the interior of the clutch inner part 20 is inserted in the locked state, and that for removing the drawer 10 of this Hollow body portion 24 by acting on the drawer forces can be separated by the clutch inner 20 without damage from the clutch outer 19.
