Description

Drawer system

Technical Field

The invention relates to a drawer system comprising a drawer and two extension guides, each having a stationary guide rail and a slide rail that can be moved relative to the guide rail, wherein the drawer is supported and held movably on the two slide rails, and each slide rail comprises a projection that protrudes in the extension direction and engages in a receptacle on the rear side of the drawer, and the drawer has a corresponding guide section that is arranged laterally next to the slide rail.

Background

DE 90 15 060 U1 discloses a drawer guide in which a locking element is provided for fixing the drawer shell, which engages over the rails of the guide and can engage with latching means on said rails. The drawer chest can thus be secured in a lateral direction (transverse direction) perpendicular to the pull-out direction by the locking element. However, the assembly of the locking element is complicated and only very small tolerance compensation is possible in the lateral direction (transverse direction) perpendicular to the pull-out direction.

DE 20 2012 003 532 U1 discloses a drawer system comprising two extension guides and a drawer cassette, wherein at least one extension rail is provided with a spring-loaded limit stop which projects from a side wall of the extension rail and bears resiliently against an inner wall of the drawer cassette. The use of such elastic limit stops to align the drawer magazine is cumbersome and ineffective if the spring force is less than the holding force when the drawer magazine is installed.

Disclosure of Invention

The object of the present invention is therefore to provide a drawer system which makes it possible to align the drawer in two extension guides by simple means.

This object is achieved by a drawer system having the features of claim 1.

In the drawer system according to the invention, the drawer is arranged movably on two rails of the extension guide, wherein, for fixing the drawer, a projection projecting in the extension direction is provided on each rail, which projection engages in a receptacle on the rear side (i.e. on the rear side of the drawer) of the drawer; is composed ofThe drawer container is aligned in the direction and is arranged laterally next to the slide rail by a guide section, wherein a laterally arranged guide element is fixed to the slide rail or is integrally formed with the slide rail, the guide element having a guide slope, the slope of which is formed from a high slope and a low slope (sich in austungschutting verj und) in the pull-out direction

In other words, the approach slope is inclined in the pull-out direction, the "inclined direction" being defined as the direction of the projection of the slope surface normal onto the horizontal plane, i.e. the direction of the slope surface from high to low), by means of which the respective guide section of the drawer slide can be aligned when the drawer slide is moved against the pull-out direction onto the slide rail. Thus, when the drawer container is slid against the pull-out direction, a forced alignment effect relative to the slide rail is produced via the guide slope, so that an automatic alignment is achieved and it is ensured that: the projection can be inserted into a receptacle on the rear side of the drawer housing. Such guide ramps on the slide rail can be produced by simple means in order to achieve a corresponding guidance during the installation of the drawer box.

Preferably, the ramp is arranged in front of the projection in the pull-out direction on the slide rail. During assembly, the drawer first contacts the guide section with the guide slope of the guide element in order to be brought into engagement with the projection during a further displacement movement against the pull-out direction.

In one embodiment, the distance between the two guide sections is greater than the distance between the two outer sides of the rail. In this case, the guide ramps can be arranged on the outer sides of the two guide rails, so that the drawer box is guided on the outer sides and the guide elements arranged there. Alternatively, it is of course also possible to provide the guide elements on both inner sides of the rails, and then to align the drawer in position by means of the guide sections arranged between the two rails. In both cases, the drawer chest can be aligned in a horizontal direction perpendicular to the pull-out direction when pushed onto the two rails.

The drawer housing preferably comprises a flat rear wall, for example made of wood, on which two openings are provided as receptacles, into each of which a projection engages, so that a secure fastening of the drawer housing is ensured. As an alternative, the projection can have a ramp surface which is arranged on the side opposite the approach ramp. In this way, when the drawer is pushed, it is aligned in a first lateral direction (transverse direction) perpendicular to the longitudinal direction by the ramp on the guide element and then is slid in the other, opposite lateral direction (transverse direction) perpendicular to the pull-out direction by the ramp surface on the projection, so that the drawer can be arranged between the guide element and the projection in an optimally aligned state without play, in particular also fixed in a clamped manner. The ramp surface on the projection and/or the lead-in ramp may be arranged inclined at an angle of between 5 ° and 45 °, preferably at an angle of between 10 ° and 20 °, with respect to the pull-out direction.

In a first variant, the approach ramp is of integral construction with the slide rail. For this purpose, the guide element can be designed as an arched bridge section which is connected at opposite ends to the side walls of the rail. The arched bridge section forms the guide slope on one side, on which the guide section of the drawer can be aligned. Or alternatively, instead of an arched bridge section, a projection web of inclined design can also be formed in one piece.

In a second alternative, the projection and the ramp are formed on a guide element which is fixed to the slide and which is separately produced. The separately produced guide element is then fixed to the slide rail, for example by welding. For this purpose, the guide element can be made of a bent metal sheet. Alternatively, the projection and the ramp may be formed as separate components and secured to the slide rail. The guide element can be fixed to a side wall of the rail, so that the projection of the guide element can be arranged above the upper surface of the rail.

The drawer system according to the invention is used in particular in furniture, wherein one or more drawer systems can be mounted on a cabinet-shaped furniture body. As an alternative, the drawer system can also be applied to a number of household appliances.

Detailed Description

The piece of furniture 1 comprises a cabinet-shaped furniture body 50 on which one or more drawer compartments 3 are held. Each drawer 3 is supported by two extension guides 2, which are arranged on opposite side walls of the furniture carcass 50. The drawer bucket 3 comprises a front panel 4, a rear wall 6 and two side frames 5 connecting the front panel 4 and the rear wall 6. The front panel 4, side frames 5 and rear wall panel 6 may be made of wood material or of other materials.

Fig. 2 shows a pull-out guide 2, which has a stationary guide rail 7, which can be fastened to a side wall of the furniture carcass 50. The extension guide 2 comprises a movable sliding rail 8, as an alternative to which at least one intermediate rail can be provided between the guide rail 7 and the sliding rail 8, which intermediate rail can be extended in an extensible manner. A hook 10 is formed on the rail 8 in the rear region, which hook can engage with the rear wall 6 of the drawer chest 3. In the front region, a stop (Stopfen) 9 is fastened to the rail 8 for fastening the drawer 3 to the rail 8. Or alternatively the coupling elements in the front region of the slide rail 8 can also be designed in other different ways.

Furthermore, an optional automatic retraction device (self-closing device) 11 is provided on the extension guide 2, which interacts with an actuating mechanism 12 on the sliding rail 8. The actuating mechanism 12 engages with a driver 13 which can be moved along a guide track on the housing 14 and can be accelerated or decelerated by means of an accumulator 15, or alternatively can be accelerated or decelerated by means of a damper. Instead of the automatic retraction 11, the device can also be designed as an ejection device for pushing the sliding rail 8 outward in the opening direction. The automatic retraction 11 or the ejection is arranged here inside the running rail 8.

Fig. 3 shows the sliding rail 8 of the extension guide 2 in more detail. The rail 8 comprises said hook 10 in the rear region and, in the pull-out direction, in front of the hook 10, a guide element 20 which, in the mounted state, is formed on a substantially vertically oriented side wall of the rail 8. The field of hooks 10 is shown in detail in fig. 4A and 4B. The hook 10 comprises an upright projecting web 16 and a projection 17, which is likewise of plate-shaped design and extends in the pull-out direction. The projection 17 here comprises a ramp surface 18 which is raised and lowered in the pull-out direction, wherein the ramp surface 18 is located on the side of the projection 17 facing away from the guide element 20.

The guide element 20 is designed as an arched bridge section and comprises a guide ramp 21 which is arranged at the front in the pull-out direction and is connected to a side wall of the running rail 8. On the rear side, there is a connecting web 22 which connects the bridge section to the running rail 8. The guide element 20 projects from the side wall of the running rail 8 by one or more millimeters, for example between 1mm and 3 mm.

Fig. 5A and 5B show the drawer housing 3 in the process of its installation on the two extension guides 2. The drawer chest 3 has two receptacles 19, which are open in the form of openings, on the rear wall 6 and which serve to receive the projections 17. The drawer 3 is first placed on the two rails 8, the drawer being spaced apart from the hooks 10, so that the hooks 10 are arranged at a distance from the receptacles 19, as is shown in fig. 5B. The drawer 3 here comprises a guide section 23 which is arranged laterally next to the slide rail 8, in the present exemplary embodiment outside the slide rail 8. The guide section 23 has a contact surface 24 which can be brought into contact with the guide element 20, in particular with the guide ramp 21, when the drawer 3 is slid against the pull-out direction, so that the guide section 23 is arranged at a predetermined distance from the sliding rail 8. The distance is selected in the following way, namely: the projection 17 of the hook 10 can be reliably inserted into the receptacle 19 on the rear wall 6 as the drawer cabinet 3 slides.

In fig. 6A, the contact surface 24 bears against the guide element 20, and it can be seen that: the contact surface 24 is positioned at a predetermined distance from the side wall of the slide rail 8. The drawer chest 3 is still in front of the hook 10. In fig. 6B, the rear wall panel 6 is shown in a view from above, still in a position spaced from the projection 17 of the hook 10. It can be seen that: the ramp surface 18 is arranged obliquely to the pull-out direction, while the projection 17 is configured parallel to the pull-out direction on the side opposite thereto. Alternatively, a ramp surface may be provided on the opposite side of the projection 17.

If the drawer housing 3 is slid further, the projection 17 engages in the receptacle 19, as shown in fig. 6C. As a result, the wall of the receptacle (which is designed as a circular hole) 19 can bear against the ramp surface 18 and bias the drawer in fig. 6C to the left, while the guide element 20 biases the drawer 3 to the right via the guide section 23, so that any play which may occur in a horizontal direction perpendicular to the pull-out direction can be avoided and the drawer 3 can be fixed in a clamping manner on the sliding rail 8.

The receptacle 19 is arranged on the rear wall 6 of the drawer chest, in which a recess 26 is provided on the underside, in which at least a part of the slide rail 8 and the automatic retraction device 11 are arranged. The recess 26 is surrounded by the guide section 23 and the middle section 25 of the drawer housing 3.

Fig. 7 shows a variant embodiment in which the rail 8 is intended to be connected to a separately produced guide element 30. The guide element 30 comprises a guide ramp 31 on a positioning lug 32 and an upwardly directed projection 33 with a projection 34. The guide element 30 can be fixed to the side wall of the slide rail 8, for example by welding. In addition, in other aspects, the drawer system may be configured as in the embodiments described above.

Fig. 8A to 8D show the installation position of the guide element 30, in which the latching lug 32 is fastened to a vertical side wall of the sliding rail 8. It can be seen that the ramp 31 is arranged in front of the projection 34 in the pull-out direction and can have the effect of aligning the guide section 23 of the drawer 3, as already explained in connection with fig. 6. When the drawer 3 is pushed, a predetermined distance is formed between the outer side wall of the sliding rail 8 and the guide section 23, so that the projection 34 can be inserted into the receptacle 19. The projection 34 can extend parallel to the pull-out direction or be oriented at a slight incline, in particular to form a ramp surface, in order to be able to clamp the drawer between the projection 34 and the ramp 31 and the positioning lug 32. Alternatively, the protruding part 34 and the guide slope 31 may be made of a separate member. Furthermore, it is also possible to combine the two embodiments described with one another, for example by providing the ramp 31 by means of a separate guide element, while the hook 10 is constructed integrally with the slide rail 8. For a multi-part design, the guide element 30 can also be equipped with a mechanism for adjusting the guide element 30 in at least one spatial direction. At a distance from the ramp 31, the guide element 30 can be provided with a downwardly directed projection as an actuating mechanism for the automatic retraction device, the damping device and/or the ejector, or as a locking mechanism.
