The invention relates to a drawer with two drawer frames, on each of which a pull-out rail of a drawer guide set is detachably fastened, each pull-out rail having a hook at its rear end, with which it can be suspended in the drawer and the drawer is spring-loaded or acted upon by a spring Has locking parts, which each snap into a recess in the pull-out rail and rest against a locking edge of the pull-out rail and each drawer frame has a hook part which receives the front end of the pull-out rail.
In particular, the invention relates to drawers with drawer slide sets in which the pull-out rails and the mounting rails cannot be separated. In general, the roller parts are stored in carriages in such drawer slide sets.
According to the prior art, two types of drawer slide sets are known, in which the rollers are not attached directly to one of the rails, but are located in a separate carriage. The best-known of these are the so-called ball roller extensions, with the load being transferred between the rails by means of steel balls which are held in a carriage designed as a ball cage.
The other type of pull-out guide sets has only recently appeared on the market and has cylindrical rollers, of the same type that are normally mounted directly on the rails. These rollers, like the balls, are held in a carriage. The carriage itself does not transmit any forces.
Drawers and pull-out guide sets have now become known in which it is possible to assemble the pull-out guide set in its entirety, ie with the pull-out rail or the pull-out rails, in the furniture body and then to hang the drawer in place.
These designs also allow the drawer to be easily removed, for example for cleaning the same.
Examples of this are shown in AT-PS 384 535 and in DE-GM 89 03 741.
So that the drawer is locked on the pull-out rails, a resilient latching part of the drawer must snap into a recess in the pull-out rail. For this it is necessary that the position of the recess on the rail and the locking part on the drawer are exactly matched. In practice, however, there are always inaccuracies that prevent the snap-in part from snapping smoothly into the recess in the pull-out rails. So z. B. the drawer guide set with the support and pull-out rails with respect to the depth of the furniture too far forward or too far back. This may be due to an assembly error or that errors occurred when drilling the row of holes used for fastening. In some cases, a buffer is installed between the drawer panel and the body. Experience shows that these buffers are not of the same height, so that the drawer protrudes more or less far into the furniture body.
The object of the invention is to improve such drawers, as far as the hanging of the drawers in the pull-out guide set is concerned. In particular, it should be ensured that the drawer is always locked on the pull-out rails when it is inserted into the pull-out guide set. It should be noted that the insertion path of the drawer in the depth of the furniture is limited by the front panel, which strikes the front sides of the furniture side walls, and that the pull-out rails are not always exactly to the millimeter in the position in which the locking parts on the Fit the locking edge of the pull-out rail.
The object of the invention is achieved in that the latching parts offset several in the pulling direction of the drawer Have stop surfaces, one of which abuts the locking edge.
A preferred embodiment of the invention provides a release part fastened to the drawer frame and arranged below the latching part. The locking part can be pressed out of its anchoring by means of the release part. This would in itself be possible by hand even without a special release part, but there is then the risk of being injured when the drawer is pulled out.
While it is possible that the stop surfaces together form a continuous bevel, which lies in the angle of friction to the locking edge, it is advantageously provided that the stop surfaces are arranged in stages.
In this way, when the drawer is pushed onto the pull-out rails, one step at a time can come to rest on the latching edge.
Another embodiment of the invention provides that the hook part of the drawer frame is directed towards the hook of the pull-out rail and that the release part is integrally formed on the hook part.
In this way, the drawer is also secured at the front against lifting off the pull-out rails. The hook part also forms a stop for the drawer and the release part is therefore always clearly positioned.
Further preferred features of the invention are the subject of dependent claims 5 to 13.
Exemplary embodiments of the invention are described in detail below with reference to the figures in the accompanying drawings.
Fig. 1 shows a schematic cross section through a drawer according to the invention, Fig. 2 shows a longitudinal section through a drawer according to the invention and a first embodiment of a rail lock according to the invention, Fig. 3 shows a plan view of the front End of a pull-out rail, FIG. 4 shows the profile of the pull-out rail, FIG. 6 shows a cross section through the lower region of a drawer frame, FIG. 5 shows a section along the line VV of FIG. 6, FIG. 7 shows a horizontal section through the drawer frame in the area of the pull-out rail and the locking and release part, FIGS. 8 and 9 each show a vertical longitudinal section through a drawer frame and the pull-out rail in the area of the locking part and the release part, FIG. 10 shows a side view of a drawer frame with a second embodiment of the rail lock, FIG. 11 shows an exploded view of the parts of the rail lock and the pull-out rail, FIG. 12 shows a diagram of the locking part and the release part of this exemplary embodiment, FIG. 13 shows a diagram of a left hook part and a left pull-out rail 14 shows a diagram of a right hook part and a right pull-out slide ne and Fig. 15 shows a side view of another embodiment of the rail lock.
The drawer according to the invention consists in the usual way of the two drawer frames 5, the drawer rear wall 7, the bottom 6 and the front panel 8.
The drawer frames 5 are advantageously extruded from aluminum, but can also be made from plastic. Each drawer frame 5 is double-walled and has a lower horizontal cover web 9.
The drawer frames 5 furthermore have horizontal webs 10, 11 which encompass the drawer base 6. Furthermore, the drawer frames are provided with a side cover web 12, behind which the pull-out rail 4 is inserted. The pull-out rail 4 has, as can be seen from FIG. 4, an upper and lower horizontal web 4 ', a continuous vertical web 4''on one side which connects the two horizontal webs 4' and an edge web 4 '''on the other side on.
As can be seen from FIGS. 3, 13 and 14, each pull-out rail 4 is provided with a narrower section 13 at its front end. In this narrower section 13 there is a recess 14, on the front edge of which the locking edge 15 is provided.
At the rear, each pull-out rail 4 is provided with a hook 16, which engages directly in an opening 17 in the drawer rear wall 7 or the drawer frame 5.
The horizontal web 9 of each drawer frame 5 is provided with an opening 18 in the front area.
The resilient locking part 2 projects through this interruption 18. In the exemplary embodiment according to FIGS. 2 to 9, the locking part 2 is mounted directly on the drawer frame 5 and points forward, ie. H. facing the front panel 8, a plurality of stop surfaces 20 arranged in a step-like manner.
A release part 1 is arranged below the locking part 2 and below the horizontal web 9 of each drawer frame 5. The release part 1 is made in one piece with a hook part 19 and, like the catch part 2, is advantageously injection molded from plastic. However, this material selection is not mandatory. For example, stamped sheet metal parts can also be used.
If the drawer is placed on the pull-out rails 4, the pull-out rails 4, as can be seen in FIG. 8, are pushed into the hook part 19 with their front end. The drawer is therefore also secured at the front against being lifted off the pull-out rails 4.
At the back, the hook 16 of each pull-out rail 4 projects into the corresponding opening 17 in the drawer rear wall 7 or in the drawer frame 5. The drawer is therefore secured against lifting off, but could be pushed out of its anchoring. To prevent this, the locking part is 2 intended. The locking part 2, which is mounted within the drawer frame 5 on the horizontal web, protrudes through the opening 18 and the recess 14 in the pull-out rail 4, and one of its stop surfaces 20 comes to rest behind the locking edge 15 of the pull-out rail 4. As a result, the pull-out rail 4 is secured against displacement with respect to the drawer frame 5.
However, in order to be able to remove the drawer completely from the furniture body and therefore to detach it from the pull-out guide set, it is sufficient to push the latching part 2 out of the recess 14 from the bottom upwards. So that you do not injure yourself, the release part 1 is provided immediately below the locking part 2. The operator presses the release part 1 and thus lifts the locking part 2 out of the recess. It cannot be injured by the retracting pull-out rail 4.
As already mentioned, both the latching part 2 and the release part 1 with the hook part 19 are advantageously injection molded from plastic.
The latching part 2, which is approximately fan-shaped in a side view, is held on a mounting block 23 by means of a retaining web 22.
Furthermore, the latching part 2 has a knob 24 with which it is suspended in a notch-shaped recess 25 of the mounting block 23. During the pivoting movement of the locking part 2, the knob 24 and the notch 25 form the fulcrum.
In the exemplary embodiment according to FIGS. 10 to 13, the latching part 2 'is designed as a slide which is mounted in a housing 26 and is vertically displaceable in the latter.
The housing 26 is fastened to the drawer frame 5, for example held by means of a screw which can be screwed into a threaded part 27 in the housing 26 and clamps the housing 26 to the drawer frame 5.
The housing 26 is further provided with a resilient tab 28, which brings the latching part 2 'down into its latched position.
Like the latching part 2, the latching part 2 'is again provided with step-shaped stop surfaces 20. Two pins 29 limit the displacement of the locking part 2 'by striking frame parts 30 of the housing 26.
The detaching part 1 'is directly molded onto the latching part 2'. The release part 1 'has seen in the direction of the longitudinal extension of the pull-out rail 4 U or C profile, so that it does not hinder the pull-out of the pull-out rail 4 from the drawer frame 5 in the release position.
13 and 14 show the front ends of the pull-out rail 4 and the hook part 19th
The hook part 19 of the right drawer frame 5 is provided with a vertical web 31 which projects into a corresponding slot 32 of the pull-out rail 4 which is open towards the front. As a result, the pull-out rail 4 is positioned with respect to the side of the drawer. The left hook part 19 has a smaller web 33 which, in the pull-out rail 4, can only strike against an edge 34 of a recess 35, so that lateral play of the pull-out rail 4 is possible on this side.
Furthermore, the hook part 19 has a roof-shaped nose 36 at the front end, which is also accommodated with play in a punched hole 37 in the pull-out rail 4. The nose 36 prevents the pull-out rail 4 from being unintentionally pulled out of its anchoring.
15 shows a further exemplary embodiment of a latching part 2 '. The locking part 2 'is again designed as a slide, which is received in a housing 26 of the drawer 5. The latching part 2 'is supported by a spring 38, which in the exemplary embodiment is a coil spring.
In order to prevent the latching part 2 'or the slide from being pushed completely out of the housing 26, this is laterally provided with a nose 29 which is pressed by the spring 38 against a stop 40 of the housing 26.
The function of the locking part 2 'is completely the same as the function of the locking parts 2 and 2' in the previously described exemplary embodiments.
In the figures of the drawings, the mounting rail fastened to the furniture body is also designated by 3. The carriages with rollers or balls are not shown. The terms right and left refer to a viewer standing in front of the drawer and looking at it.
