Description

The present invention relates to a drawer for a furniture, wherein the Drawer both toward the front and in the direction of Back of the furniture is pulled out of this and according to his Front and back drawer covers, which alternately with the Drawer or the furniture body can be coupled.

Drawers for furniture of the generic type are known per se.

For office furniture, room dividers, for hospital furniture, tables or the like. Are Constructions useful in which a drawer on both sides of a Furniture carcass is pulled out.

It is necessary that the two-sided drawer panels on the one hand opposite the furniture body and on the other hand coupled to the drawer are such that the drawer panel on the side of the furniture to which the drawer to be pulled out, is coupled to the drawer and the opposite drawer front panel exclusively with the Furniture body coupled and separated from the drawer.

In order to meet these demands are sometimes complex transmission mechanisms been used, in which a handle is needed, the Purposes of coupling a drawer panel with the drawer across to the actual Actuation direction of the handle is to move.

It has already been proposed an improved version in which the Coupling a drawer panel with the drawer by a relative movement a handle to the respective drawer panel in the pulling direction sufficient is (DE-GM 203 12 325).

The present invention is based on the object, a drawer of generic type to create, which is characterized by a particularly simple way and Way of coupling between drawer panel and drawer excels.

This object is achieved in that for the coupling of Drawer panels with the drawer on the one hand and the furniture body on the other Driver or interlocks are provided, which exclusively by the pull-out or insertion movement of the drawer panels and the Drawer are controlled.

The advantage of the construction according to the invention is that the required Coupling or decoupling operations solely by the shift the drawer trims and / or the drawer are effected so that further, dependent on a handle and its operation transmission means are dispensable.

Thus, a furniture manufacturer can freely decide whether and, if so, what kind of Handling on the drawer trims of a drawer according to the invention should be attached.

A preferred embodiment of the invention is that the driver from attached to the drawer trims movable, claw-like moldings exist, each with a pulled out in the opening direction Drawer panel a counterbox-side counterpart engaging behind Mitnehmerhaken are equipped, wherein the driving hook befindlicher in the closed position Drawer panel outside the engagement area to the respective counterpart lies.

With inserted drawer and in closed position to a furniture body moved drawer blinds are thus all with claw-like moldings their catch hook outside the active or engagement area to the counterparts of the drawer.

Will now one of the drawer trims in the sense of pulling out the drawer pulled away from a furniture body of this, so at the concerned drawer panel provided, claw-like moldings with the associated counterparts of the drawer brought into driver connection, so that a further pulling movement at the drawer panel in question Pulling out the drawer from the furniture body has the consequence.

A subsequent pushing back of the drawer to its closed position then again has a decoupling between drawer and drawer panel result.

Thus, all drawer panels are opposite the drawer in the closed position decoupled. This allows the drawer easily in both directions to pull out of a furniture carcass. In each case, this is the extract page Opposite drawer panel opposite the furniture body coupled.

Another embodiment of the invention provides that the driver from on the drawer hinges pivotally mounted driving levers and on Drawer mounted driving lugs exist, with the driving lever at in the closed position drawer trims outside the range of Driving lugs are.

Again, from this basic position, a drawer in both directions be pulled out of a furniture carcass. This is done by pulling at a drawer panel and concomitant, immediate coupling of Drawer panel with the drawer itself.

The opposite drawer panel is in turn opposite to the Furniture carcass coupled.

Further features of the invention are the subject of further subclaims.

With reference to Figs. 1-12, a first will now be given Embodiment of the invention described.

In these figures 1 to 12, the reference numeral 1 of the furniture body of a not shown furniture referred to. This furniture is with one equipped with the reference numeral 2 designated drawer, which to both the front and the back of the furniture from this can be pulled out.

The drawer 2 is equipped on both sides with drawer 3, which alternately with the drawer 2 and the furniture body 1 can be coupled.

For coupling the drawer 3 with the drawer 2 are drivers. 4 provided, which from connected to the drawer 3 movably connected consist claw-like moldings 5, which have a driving hook 6, the in the opening direction partially pulled drawer panel a schubkastenseitiges Counterpart 7 engages behind, as in the figures 4) and 6) particularly is shown clearly.

The driver 4 described are each in the corner regions of the drawer 2 connected to the drawer panel 3 and parallel to the drawer panel 3 movable. In this case, the drivers 4 are each only schematically indicated spring "F" in the direction of the outside of a furniture body. 1 loaded.

In Figure 2, the drawer 2 is shown in its closed position, the same applies to the drawer trims 3. From this figure 2 it is clear that in this Closed state the claw-like molding 5 against the action of the spring "F" in moved the interior of the furniture body 1 and there fitting the furniture body 1 is held. In this position, the driving hook 6 is outside the Engagement area to the respective counterpart 7. Will now the drawer panel 3 slightly pulled out relative to Figure 2, as shown in Figure 4, the claw-like molding 5 via an inclined surface 8 by the action of the spring "F" be moved in the direction of the outside of the furniture body 1. It then arrives the driving hook 6 in the engagement area to the counterpart 7 on the drawer Second

Conversely, the drawer 2 and the drawer 3 opposite to the 4) moves again in the closing direction according to FIG. 2, so can on the inclined surface 8, the respective claw-like molded part 5 back in the interior of the furniture body 1 moves back and tensioned the spring "F" become.

As described above, thus the coupling or decoupling between the drawer 3 and the drawer 2 exclusively by a relative displacement the drawer panel 3 to the drawer 2 brought about, wherein said relative displacement of the drawer trims 3 generally in the Movement or thrust direction of the drawer 2 takes place.

The coupling of a drawer panel 3 with the drawer 2 takes place at a Movement of the drawer panel 3 in the sense of pulling out the drawer 2 from the furniture body 1, inversely, the decoupling takes place when pushing back the drawer 2 in its closed position and the pushing back the drawer panel 3 to the furniture body. 1

These coupling or decoupling operations only require a shift the drawer panel 3 in the direction of movement of the drawer. For this is basically a handle on the drawer or on the drawer 3 required. To simplify handling, of course, at each Drawer 3 provides an arbitrarily designed handle or gripping aid be.

After a drawer panel 3 in the manner described above the drawer 2 is coupled, by further pulling in the extension direction via the drawer panel 3 and the driver 4 of the drawer 2 in the direction of displacement or pull-out direction taken so well as Figure 6 clearly shows.

In Figure 7, the figures 1-6 opposite side of the drawer. 2 shown, in a shift position of the drawer 2, the figure 6 equivalent.

From this figure 7 it is clear that the second drawer panel 3 at partially or completely pulled out drawer 2 coupled to the furniture body 1 is. For this purpose, a generally provided with the reference numeral 9 locking intended.

This lock 9 consists in each case of a fixable on the furniture body Holding body 10, a connected to the drawer panel 3 locking pin 11, which projects into a receiving channel 12 of the holding body 10 and from a locking lever 13, which is pivotally connected to the holding body 10 is and in the locking position in a notch 14 of the locking pin 11 is engaged. In this from Figure 7 clearly forthcoming Locking position, it is not possible, the drawer panel 3 opposite to pull the furniture body 1 to the outside.

The locking lever 13 of each lock 9 is about a pivot point 15 on Holding body 10 pivotally connected and designed as a two-armed lever. The weight distribution of the locking lever 13 is chosen so that this is constantly loaded in the locking direction due to gravity.

Alternatively, could also by a spring such a bias of the Locking lever 13 can be effected.

If the drawer 2 in the position shown in Figure 7 back to the left moves, so comes close to reaching the valid closed position of the drawer 2 a control lug 16a in the region of the locking lever 13 and pivots it such that the locking of the locking lever 13 in the Notch 14 of the locking pin 11 is canceled. This corresponds to the Position of said locking lever, as shown in Figures 1 and 3 results.

This means that when fully inserted drawer 2 and in the closed position located drawer 3 no coupling between the drawer panels 3 and the furniture body 1 is given. Each drawer panel 3 can thus be pulled out of its closed position to the outside, where then, as described above, a coupling with the drawer 2 results and the opposite drawer panel 3 forcibly with the Furniture carcass 1 is coupled.

As the perspective views in FIGS. 8 and 10 clearly show, the drivers 4 are each attached to one of the drawer trims 3 Guide member 16a movably mounted, each guide member 16a also carries a locking pin 11, which preferably integrally with the Guide member 16a is made. In addition, each guide part 16a is two Guide pin 17 provided, which in closed drawer 2 in Guiding channels 18 of molded parts 19 engage in the corner regions of the Drawer 2 are attached to this. These moldings 19 also form the Counterpart 7, to which the respective driving hook 6 of the driver 4 in Extent direction supports.

On the mold parts 19 are also the control lugs 16 for actuating the locking lever 13 integrally formed or attached to this molding 19. This example shows Figures 7 and 8 quite clearly.

In Figures 12a and 12b is formed as a claw-like molded part 5 Driver 4 shown in different perspectives. These two figures 12a and 12b make it clear that the claw-like moldings 5 in their back Area are provided with a receiving channel 20, in which one above in terms of their function generally described spring "F" to load this claw-like moldings 5 can be inserted.

In summary, once again the function of that shown in Figures 1-12 and described construction explains:

With inserted drawer 2 and in the closed position Drawer 3 is neither a coupling of drawer 3 with the Furniture carcass still given to the drawer 2. Will a drawer panel 3 now in terms of a pull-out movement of the drawer 2 from the furniture body. 1 removed, found in this area a forced coupling between the pulled drawer panel 3 and the drawer 2 instead. The on the lying opposite drawer panel 3 is during the Pulling process inevitably coupled to the furniture body 1. At the Retracting the drawer 2 and the previously pulled out Drawer 3 in its closed position again all couplings canceled. Thus, the drawer 2 from its closed position out arbitrarily be pulled out of the furniture body 1 in both directions.

Another embodiment of the invention will now be described with reference to FIG Figures 13 to 19 described.

The drivers 4a are for coupling between the drawer panels 3 and the drawer 2 from the drawer hinges 3 pivotally mounted driving levers 20. These driving levers 20 associated with driving lugs 21, which are attached to the drawer 2. When in the closed position Drawer trims 3 are said driving lever 20a outside the area the Mitnehmemasen 21, so that in this case no coupling between Drawer 3 and drawer 2 is given. This position is FIG. 13 shown. Now, the drawer panel 3 shown in Figure 13 is somewhat in the extension direction moves, as shown in Figure 14, the driving lever 20a sets behind the associated Mitnehmemase 21 so that now a further pulling the Drawer 3 in the above-mentioned direction entrainment of the Drawer 2 takes place in the sense of opening. The control of the swivel movement the driving lever 20a via control cam 22, which is connected to an am Furniture carcass 1 fixable base plate 23 are provided.

The coupling between a drawer panel 3 and the furniture body 1 takes place about a lock in the form of the furniture body 1 pivotally mounted Locking levers 24 and attached to the drawer 3 Locking pieces 25. The locking levers 24 are at their drawer panels 3 facing ends provided with a notch 26, which coupled in Condition of one of the said locking pieces 25 receives positively. This is shown clearly in FIG. 16. The locking levers 24 are as one-armed Lever pivotally connected to the base plates 23. Thus, the Locking lever 24 by gravity into the locking position shown in FIG 16 pivot as soon as these locking lever 24 a fixed to the drawer 2 Have left cam 27. By this cam 27 are reversed but again the locking lever 24 from its coupling position 16 pivoted upward in a release position when the drawer 2 is fully inserted and the drawer 3 is their closed position have taken.

Both the pivoting movement of the driving lever 20a as well as the pivoting movement the locking lever 24 may, for example, by a spring get supported. Each opposite movement in the sense of decoupling then takes place exclusively by the control cam 22 and the cam 27th In the embodiment of the invention according to the figures 13 to 19 are the two drawer panels 3 independent of the guide means of the drawer 2 Sliding guides 28 are connected and used by these sliding guides 28 worn. For fixing the position of the drawer trims 3 in the closed position is still a bracket 29 is provided on each drawer panel 3, the in Closed position enclosing a locking cam 30 on the furniture body 1 by clamping.

Also in the embodiment of the invention according to the figures 13 to 19 are the Drawer trims 3 with inserted drawer 2 and in closed position located drawer 3 with neither the drawer 2 still with the Furniture carcass 1 coupled. Only then, if one of the drawer 3 in the Meaning of a pull-out movement of the drawer 2 from the furniture body 1 out is deducted from the furniture body 1, results in respect of this drawer panel 3 first, a coupling with the drawer 2 and over the Mitnehmerhebel 20a and the driving lugs 21. The opposite drawer panel 3 is characterized in that now the drawer 2 of the latter Drawer panel 3 removed, forcibly coupled to the furniture body 1, by the locking lever 24 and the locking pieces 25th

Thus, the drawer 2 together with drawer panel lying in the extension direction 3 are conveniently opened, while the opposite drawer panel 3 fixed to the furniture body 1 and not deducted from the furniture body 1 can be.

After the return of the drawer 2 in its insertion position and after the drawer front panel 3 pulled out again into its closed position is brought back, a state is brought about again, in which all couplings of the Drawer trims 3 are repealed. Thus, again in any Toward a pull-out movement of the drawer take place.

All embodiments have in common that the above described in detail Components of the respective latches or drivers advantageously from Plastic are made.
