Description

Pull-out guide for a drawer

The present invention relates to a drawer slide for a drawer, with a sliding rail which can be coupled to a drawer, with a front and a rear coupling device, which serve for fixing the drawer on a running rail.

Pull-out guides of the generic type are known per se and have proven themselves in practice.

Of course, two drawer guides of the generic type are necessary for a drawer to store a drawer within a furniture body displaceable can.

Accordingly, the drawer guides also each have a cabinet rail which can be fixed to a furniture carcass and, between the carcass rail to be considered stationary in the assembled state and the runner rail which is movable in the coupled state with a drawer, it is also possible to arrange an extendable center rail.

The fixation of a drawer on a running track is done so far in such a way that a drawer is placed in the correct position on the two rails of the drawer guides mounted in a furniture body and inserted into a final closed position in the furniture body. In this case, the lifting of the drawer in the rear area and by the front coupling device both a lifting of the drawer in this front area as well as a coupling in the extension direction made so far by the rear coupling device, so that the drawer can not be removed in the extension direction of the rails ,

When properly installed, the function of the known pullout guides is flawless and safe.

If, during a first installation or after a user once, for example, for cleaning purposes, a drawer completely disconnected from the rails and want to reinstall, the drawer inserted not far enough, there is a risk that the proper coupling is not becomes effective, so that with a movement of the drawer in the opening direction there is a risk that the drawer can be completely withdrawn from the rails, since no extract safety has occurred here. The drawer could fall down so far and hurt the user, au ßerdem the drawer can of course also be damaged when dropped.

The present invention is therefore based on the object to improve a drawer slide of the generic type to the effect that the security against assembly errors with the attendant risk of injury of a user is substantially increased.

This object is achieved by a further coupling device which secures the drawer at least against a pulling down of the track before at least one of the other two coupling devices with the drawer is engaged.

This ensures that a trigger lock for the drawer is already effective before an effective fixation of the drawer has taken place with the well-known coupling devices. Although it is to be assumed that even a technically less experienced user will be in the assembly of a drawer endeavors to effectively couple the drawer with the two coupling devices of the rails of two corresponding drawer guides. However, if the user in this case inadvertently brought about this coupling has not been safely prevented by the already before becoming further coupling device between the rails and the drawer pulling down the drawer of the rails, which already described at the outset dangers of complete release of the drawer are reliably prevented by the rails.

From DE 83 02 002.0 a running rail is known, which is equipped in its rear region with a fishing hook, which passes in the mounted state, an opening of a rear wall of a drawer and has a detent which rests in the mounted state barb-like on the inside of the rear wall and prevents such a pulling down of the drawer of the running rail. The difference to the construction according to the present invention is essentially that in the prior art of Projection the rear wall only with fully inserted drawer engages behind.

This means that even in the prior art, a secure coupling or fixation of the drawer with two rails ultimately only reached when the drawer is fully inserted into its insertion position. Thus, the advantages of the construction according to the invention can not be achieved. A preferred embodiment of the invention is that the rear coupling device and the further coupling device form a structural unit.

In this case, advantageously, the rear coupling device consist of a breakthrough of a rear wall or lying in the backplane of a drawer Zargenadapter passing through hooks, wherein the fishing hook is resiliently provided to the running rail or provided with a spring rail to the running rail lever, wherein the fishing hook or the spring-loaded Lever is in each case equipped with a hook-shaped projection designed as an undercut, which forms a trigger lock for a drawer in coupled drawer and wherein the projection protrudes with coupled drawer over the back of the drawer out in the direction of the front end of the running rail. As a result, a unit is created, which also forms a lift-off in the drawer in the rear end and also forms a pulldown of the drawer of the running rail, if not both coupling devices of the drawer have become effective for its secure fixation on the running rail.

In this case, the catch hook can advantageously be made of a spring steel wire manufactured in one piece with the projection.

An advantageous embodiment of the invention is also given when the spring-loaded lever is pivotally connected to a hook-like support member.

In the latter case, it may be of particular advantage from an economic point of view if a catch element known per se as a hook-like carrier part is used. hook, which has hitherto been used on comparable pull-out rails.

The additional coupling device can also be designed as a separate arrangement. Thus, it is possible, for example, that the additional coupling device consists of a protruding out of the running rail and a projection tab with a recess in a Zargenadapter a drawer, with a kinematic reversal is also conceivable, in which therefore on a Zargenadapter a flared Tab is provided which can engage in an associated recess of the running rail.

Also possible is an embodiment of an additional coupling device in the form that is formed on a Zargenadapter a drawer extending in the direction of the rear end of the track and provided with a projection tab, which already engages behind the rear coupling device when an effective fixation of the drawer is not yet made by the two coupling devices.

The drawer slide according to the invention for a drawer can be used both in furniture, as well as in household appliances, tool cabinets or the like.

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

In the figures 1 and 2, reference numeral 1 denotes a furniture body, in which at least one drawer 2 is slidably disposed. The drawer 2 is equipped at its front end with a front panel 3, which rests with the drawer 2 closed on the front side of the furniture body 1, as shown in Figure 1.

The drawer 2 is in a conventional manner via two pullout guides

4 slidably arranged in the furniture body 1. Each drawer guide 4 consists in a conventional manner of a body side fixable carcass rail

5 and also has a running rail 6, with which the drawer 2 is coupled. Since the running rail 6 and the type of coupling of the drawer 2 with this running track 6 constitute the core of the present invention, for simplification of the illustration in FIGS. 6 to 11 and 15 to 18, only one running rail 6 of a pull-out guide 4 according to the invention is used shown and from the drawer 2, only one Zargenadapter 7 is shown, which is an integral part of a drawer 2, so that can be dispensed with the presentation of the remaining drawer parts here.

Generally applies to all embodiments, which will be described that a drawer 2 on the rails 6 of the drawer guides 4 can be fixed by a front and a rear coupling device. The front coupling device serves to secure the drawer 2 both against lifting as well as pulling down from the rails 6. The rear coupling device serves to fix a drawer 2 against lifting relative to the rails 6. Only as a possible embodiment of a front coupling device, the rails 6 are each provided in their front, end-side end portions with an 8 provided with notches recess 9, within which a schubkastenseitiges and generally designated by the reference numeral 1 0 locking element is latchingly receivable. This is apparent for example from Figures 1 5 and 16.

If the locking element 1 0, which is attached to the drawer 2, is engaged within the recess 9, a withdrawal of the drawer 2 of the running rail 6 in the longitudinal direction of the running rail 6 is no longer possible. The latching element 1 0 is designed so that only a raising of the drawer 2 with separation of the locking element 1 0 of the running rail 6 can be carried upwards, which is possible only with a certain amount of force, so that an unintentional lifting of the drawer in the front Range is not possible.

Generally 6 coupling devices are provided in the rear end of the rails that prevent only the lifting of the drawer of the rail 6.

In order to avoid pulling down of the drawer from the running rail 6, when the two mentioned coupling devices have not yet fixed the drawer 2 properly on the running rail 6, a further coupling device is provided which secures the drawer 2 at least against a pulling down of the running rail 6, before at least one of the other two coupling devices is engaged with the drawer 2. This will now be explained in detail.

In the embodiment of the invention according to Figures 6 to 1 7 a fishing hook 1 1 is fixed in the rear end region of the running rail 6, which consists of a hook-like support member 1 2 and a pivotally mounted thereto lever 13, wherein the lever 13 is an opening 14 in the Rear wall level leg of the frame adapter 7 passes.

The lever 1 3 is spring-loaded in a manner to be described in such a way that this lever 13 is constantly charged to the running rail 6 out. At the bottom of the lever 13 is provided with a trained as an undercut hook-shaped projection 1 5, which overlaps the passage of the lever 1 3 through the opening 14 the corresponding portion of the frame adapter 7 from the drawer inside.

Thus, after the insertion of the lever 1 3 and the rear engagement of the frame adapter 7 or according to a rear wall, a separation of the drawer 2 of the running rail 6 is no longer readily possible. It is effectively formed a trigger lock for the drawer 2.

This trigger lock is already effective before the arranged in the front region of the drawer 2 locking element 1 0 locked in the recess 9. In other words, an unintentional removal of the drawer 2 is already prevented by the running rail 6 before the drawer 2 in the intended manner in the front end region of the running rail 6 finally locked and secured in the direction of displacement. As shown in particular Figures 1 2 to 14, the lever 1 3 is formed from a cap-like and the support part 1 2 from above cross-shaped part. At this molding a spring portion 1 3a is formed for example by a free cut, which rests with its free end 1 3b on the underside of the front end of the hook-like support member 1 2, which show the figures 1 3 and 14 very clearly. By this spring portion 1 3a, the lever 1 3 is constantly down, that is loaded in the direction of the running rail 6, as has already been mentioned several times.

At its front, front end of the lever 1 3 is provided with a curved rounding 1 3c, which is guided and raised at the entrance of this lever 1 3 in the region of the opening 14 of the frame adapter 7 over the lower boundary edge and so that this Rounding can be referred to as a drive-in for the lever 1 3 in the region of the opening 14. It would also be conceivable to provide an exact insertion bevel here.

The pivotable mounting of the lever 1 3 on the support member 1 2 takes place for example by from the lever 13 in opposite directions to each other Bearing hook 1 6, which in a bearing bore 1 7 (which can be seen in the illustration of Figure 1 7) engage.

Thus, additional connecting parts such as bearing bolts or the like are not required and the assembly is also relatively simple.

Preferably, the lever 1 3 as well as the angle-shaped support part 1 2 are each made in one piece from metal. In this case, the lever 13 is preferably formed from a spring plate as stamped, bent part.

In the figures 1 8 and 1 9 an embodiment of the invention is shown, in which the fishing hook 1 1 made a total of one piece and made of a spring steel wire, which is attached, for example, to a hook-like support member 12, as in the embodiment of the remaining figures for the storage of the lever 1 3 is used.

Of course, the catch hook 1 1 manufactured in one piece from spring steel wire can also be fastened to another bearing part, which in turn is firmly connected to the running rail 6.

The bent spring steel wire of the fishing hook 1 1 according to the embodiment shown in Figures 1 8 and 1 9 is provided in its front end with a loop-like bend 1 8, the free end is below the remaining portion of the wire and thus forms a projection 1 5 which rests after passing through an opening 14 on the inside of the corresponding frame adapter 7 or a rear wall and thus can form a trigger lock, as shown clearly in Figure 1 9. By bending 1 8 in turn a comfortable insertion of the appropriately designed fishing hook 1 1 is ensured in the region of the opening 14.

In order to be able to release a drawer 2 as required, despite the design of the catch hook 1 1 as a trigger lock, the following procedure is required:

First of all, the drawer 2 is to be pulled out of the furniture carcass 1 into a pull-out position, preferably into a maximum pull-out position. In the pull-out position, preferably in the maximum pull-out position, the Drawer 2 is then released in its front end by lifting from the running rail 6, wherein at the same time the front end of the fishing hook 1 1 is lifted against the spring action so far that the projection 15 is above the lower edge of the opening 14. Thus, now the drawer 2 can be pulled further forward and thus completely separated from the running rail 6.

The above-described separation of the drawer from the running rail 6 is also possible in all other embodiments to be described in the manner indicated.

Due to the total length of the fishing hook 1 1, the possibility is created according to the present invention to effect a trigger lock for the drawer 2 quite quickly, that is in the present case, after a relatively short insertion depth of the drawer 2 in the furniture body. 1 In any case, the trigger lock should already be effective when a locking of the drawer 2 in the front end face region of the running rail 6 is not yet done. As a result, an unwanted removal of the drawer 2 of the running rail 6 and the associated risks are avoided.

The exploded view of Figure 1 7 shows once again in a particularly clear form that the lever 1 3 pushed onto the angular support member 12 and by the mutually oppositely pronounced bearing hooks 1 6, which can engage in a bearing bore 1 7 of the support member 1 2 pivotally the carrier part 1 2 is connectable.

Figures 20 to 22 show an embodiment of the invention, in which from the running rail 6 is an upwardly issued and a projection bil- forming tab 1 9 is provided which can engage in a recess 20 of the frame adapter 7 of limited length. If the drawer 2, shown here representatively represented by the frame adapter 7, inserted into the fully secured position, there is the upwardly flared tab 1 9 without an effect within the length range of the recess 20, as Figure 22 shows this. Figures 20 and 21 make it clear that in the event that a proper fixation of the drawer 2 relative to the running rail 6 has not yet taken place in an attempt to pull the drawer 2 from the running rail 6, the flared tab 19th to a front end 21 of the recess 20 abuts, whereby the removal of the drawer is prevented by the running rail 6.

If intentional separation of the drawer 2 from the running rail 6 is to be effected, this can be done in the usual way by raising the drawer 2.

FIGS. 20 to 22 thus show an additional coupling device independent of the rear coupling device in the form of a rigid catch hook 22.

FIGS. 23 to 25 to a certain extent show a kinematic reversal of the exemplary embodiment according to FIGS. 20 to 22, in which a flared lug 1 9, which may also be designed as a spring element, is provided on the frame adapter 7, which recess is in a recess 20 of the running rail 6 can engage.

Figures 26 to 31 show an embodiment in which at the rear end of the frame adapter 7 is provided in the direction of the rear end of the rail 6 ersteckende tab 23 which is configured with an angled, acting as a projection end piece 23a and with this End piece 23a can engage behind an angle-like catch hook 22, if a proper fixation of the drawer 2 relative to the running rail 6 is not yet given.

Also in this embodiment, it is possible to bring about a deliberate separation of drawer 2 and running rail 6 by lifting the drawer in its front region, as indicated in Figures 30 and 31.

The illustrated embodiments make it clear that there are a variety of ways to provide coupling devices that provide a secure fixation of the drawer 2 relative to a running rail 6 and there are also a variety of ways for the arrangement of an additional borrowed coupling device by means of which a trigger lock for the drawer 2 is already given, if the two other coupling devices are not yet effective. In that regard, the illustrated embodiments are to be regarded as possibilities, of which there are quite a variety of deviation possibilities.
