Description

Drawer and furniture

The present invention relates to a drawer with at least one drawer guide arranged there, the drawer guide having a drawer rail which can be moved relative to a carcase rail, the carcase rail being fixable to a furniture body or appliance body and the drawer being supported on at least one movable drawer rail, wherein the drawer has a base, a front panel, a rear wall and two side frames which connect the rear wall to the front panel, the side frame being at least partially made of metal and a fastening device for fixing the front panel being provided within the side frames and in the rear Area of the drawer rail or the drawer an adjusting device for adjusting the inclination of the drawer relative to at least one of the drawer rails is provided, and a piece of furniture.

DE 203 12 304 U1 discloses a drawer in which a front panel can be tilted relative to the two drawer frames. As a result, the inclination of the front panel relative to the side frames can be changed in order to obtain a flush arrangement of adjacent front panels in a piece of furniture. When adjusting the inclination of the front panel, it is disadvantageous that gaps can form between the front of the side frame and the front panel, which can be visually disadvantageous and dirty when the drawer is opened.

In the case of drawers, devices for flea adjustment can also be provided in the rear area of a pull-out guide, as are known, for example, from DE 10 2015 106 789 A1. These allow the drawer to be raised in the rear area, so that when a front panel is rigidly connected to a side frame, the inclination of the front panel can also be adjusted to a small extent, but only by lifting the drawer around the front panel in the closed position in the to pivot the upper area further outwards. A lowering of the drawer in the rear area is not possible with the adjustment device, so that the setting options are limited. It is therefore an object of the present invention to create a drawer which enables improved adjustment with regard to the alignment of the front panel and also avoids the formation of a gap between the front panel and the side frame.

This object is achieved with a drawer with the features of claim 1.

In the drawer according to the invention, the side frames are aligned on the front side facing the front panel at an angle of less than 90 ° to the longitudinal direction of the side frame, and the front panel is substantially flush and gapless on the front side. Such a blunt position on the front panel on the front side prevents gaps between the side frames and the front panel. The angle of less than 90 ° of the front panel to the longitudinal direction of the side frame ensures that when the side frame is aligned with its longitudinal direction exactly horizontally, for example on a horizontally oriented drawer rail, the front panel slightly protrudes with an upper region to an inside of the furniture body. By lifting the drawer by the adjusting device for adjusting the height of the drawer in the rear area, the front panel can then be aligned exactly vertically or, if necessary, the top of the front panel can also be arranged slightly protruding outwards from the furniture body. The adjustment range for the front panel thus extends in both directions from a medium vertical position.

The longitudinal direction of a side frame can be defined by the top and the bottom of the side frame, if these are aligned parallel to each other. Ideally, the longitudinal direction of the side frame can be aligned horizontally in the mounted position.

The angle of the end faces of the side frames to the longitudinal direction of the same is preferably in a range between 88 ° and 89.9 °, in particular 89.4 ° to 89.9 °. The slightly angular orientation of the face to the normal, which is oriented perpendicular to the longitudinal direction, leads to a change in a "zero position" at which the front panel is aligned exactly vertically. This will move the zero position to another point in the adjustment range. When adjusting the inclination of the front panel, minor angular deviations on the bottom of the drawer are not noticed by the user. The adjusting device for adjusting the height of the drawer can preferably be fixed on the drawer rail. For example, a height-adjustable hook can be provided which engages in a receptacle or opening on the rear of the drawer. Alternatively, a slide or another adjustment element can be provided on which a bottom or the rear wall of the drawer rests.

Alternatively, the adjusting device for adjusting the height of the drawer can be fixed on the drawer. For example, an adjustable foot can be provided. The adjustable foot can engage in a hook or an opening on the drawer rail of the pull-out guide. Alternatively, the inclination of the front panel of the drawer can be adjusted by an adjusting device integrated in the drawer or by other devices as are known in the prior art.

In a further embodiment, the side frames have at least one cover made of a metal sheet. The adjusting device for fixing the front panel can be arranged within the cover. The end faces of the cover made of sheet metal preferably also form the end face of the side frame, which are oriented at an angle of less than 90 ° to the longitudinal direction of the side frame. The metal sheets required in the manufacture of the side frame can be cut poorly during further processing, so that a corresponding angle of the end face is seen before during manufacture. In contrast to side frames made from a wood material, the metal sheets are difficult to machine afterwards when the furniture is being assembled.

The pull-out guide on the drawer is preferably designed as an underfloor pull-out guide. The drawer rail can at least partially be accommodated in the side frame.

The side frame is preferably arranged in a first end position, the device for height adjustment, parallel to the drawer rail and can then be wasted via the device for height adjustment in a second end position, in that the side frame is inclined to the drawer rail, for example at an angle between 0, 1 ° and 3 °. This allows a corresponding adjustment of the front panel to be made by the fixed coupling of the side frame with the front panel. A piece of furniture according to the invention comprises a furniture body on which at least one drawer can be moved via at least one pull-out guide, an alignment plane for the front panel being formed on the furniture body, for example by a front end face of the side walls of the furniture body, which has a stop for the rear of the front panel. This level of alignment is oriented vertically in most pieces of furniture, but can also be arranged at an angle to the vertical, for example if the piece of furniture has an oblique front. In any case, the side frames of the drawer are aligned on the front side facing the front panel in a lower position of the adjusting device at an angle to the alignment plane, that is to say at a vertical alignment plane at an angle to the vertical. As a result, the front panel can be adjusted in inclination by the adjusting device from a position parallel to the alignment plane in opposite directions. This allows tolerances during assembly, which can lead to an angular alignment of the front panel, in both directions. With a parallel alignment of the front side of the side frames to the alignment level, the installation of the pull-out guides on the furniture body can lead to tolerance deviations that could only be compensated in one direction for a long time if the Verstellvor direction raised the side frame in the rear area. Due to the angular alignment of the side frame relative to the alignment plane in the lowered position of the adjusting device, tolerance compensation can now be effected in both directions of inclination of the front panel.

Preferably, the angle between the alignment plane on the Möbelkor body and the end face of the side frames in a lower position of the adjusting device is in a range between 0.1 ° to 2 °. As an alternative or in addition, the level of alignment of the furniture body can specify or define a normal angle of the front panel for arrangement on the side frame. The front panel is then preferably arranged in a range of 0.1 ° to 2 °, in particular between 0.1 ° to 0.4 °, deviating from the normal angle of the front panel on the side frame.

The invention is explained in more detail below using several exemplary embodiments with reference to the accompanying drawings. Show it:

A piece of furniture 1 comprises a furniture body 2 which has side walls 3, between which an upper drawer 4 and further drawers 5 are arranged. On the side walls 3, the stationary rails of pull-out guides can be fixed. On the furniture body 2, an alignment plane for egg ne front panel 6 of a drawer 5 is formed, which is defined, for example, by the end faces of the side walls 3, on which the front panel 6 rests in the closed position of the drawer 5 or at a predetermined distance in the closed position is held, for example if a push-to-open mechanism is used to eject the drawer.

FIG. 2 shows a drawer 5 which has a front panel 6 and a rear wall 7 which are connected to one another by two side frames 8. In Figure 3, the drawer 5 is shown without the front panel 6, and it can be seen that between the side frames 8 a plate-shaped bottom 10th is provided. The side frames 8 are hollow and include adjacent to the front panel 6, a fastening device 9 for fixing the front panel 6, for example with corresponding pins or dowels that engage in openings in the front panel. A cover of the side frames 8 bil det an end face 11 which is substantially blunt against a surface of the front panel 6 in the assembled position. The end face 11 is, however, not aligned perpendicular to the longitudinal direction of the side frame 8, that is to say at an angle of 90 °, but at a smaller angle, for example between 88 ° and 89.9 °.

The drawer 5 is shown in a side view in FIGS. 4A to 4C. The angle a between a longitudinal direction of the side frame 8, which runs parallel to the underside of the side frame 8, and the end face 11 is in the win kel range less than 90 °, so that in a first position according to Figure 4A, the front panel 6 slightly inwards into the furniture body 2 protrudes into the upper area. FIG. 4B shows the position in which the front panel 6 and the end face 11 are aligned vertically, the side frame 8 of the drawer 5 being slightly raised in the rear area. This is a medium adjustment position. FIG. 4C shows a position in which the front panel 6 is slightly inclined outwards in the upper region and is no longer oriented vertically. FIGS. 4A to 4C schematically show the adjustment area for the front panel, which can be achieved by means of a device arranged on the rear of the drawer 5 for adjusting the height of the drawer 5 relative to a drawer rail 12.

In Figures 5A to 5C, the drawer 5 is shown on a schematically Darge drawer rail 12, the front panel 6 is arranged in under different positions. In the position shown in FIG. 5A, a longitudinal direction of the side frame 8 is oriented parallel to the drawer rail 12. On the back of the drawer 5, a hook 13 is provided on the drawer rail 12, which fixes a holder 14 on the drawer 5 on the drawer rail 12. On the holder 14, an adjusting element 15 is provided, which may include a threaded bolt, for example, and is adjustable in height relative to the holder 14. In FIG. 5A, the front panel 6 is arranged slightly inwards in the upper area, while in FIG. 5B the adjusting element 15 has been raised by adjusting the height of the drawer 5 in the rear area, so that the side frame 8 is oriented inclined to the drawer rail 12. By lifting the drawer 5 in the rear area, the front panel 6 is now aligned vertically. If the adjusting element 15 is adjusted further in height, as shown in FIG. 5C, the front panel 6 can be arranged slightly inclined outwards in the upper region. All angles are drawn for illustration purposes to exaggerate to explain how the adjustment mechanism works.

An alternative adjustment device for height adjustment is shown in FIGS. 6A to 6C. The drawer 5 is provided in the rear area with a holder 20 which, for example, comprises an opening or receptacle, which can also be formed integrally with the rear wall 7. A hook 23 engages in the holder 20 and is mounted on the drawer rail 12. In Figure 6A, the drawer rail 12 is again aligned parallel to the longitudinal direction of the frame 8 Be, and the front panel 6 protrudes slightly inwards to the furniture body. If the hook 23 is raised via an adjusting device 21, as is shown schematically in FIG. 6B, the front panel 6 can be aligned vertically, and the side frame 8 is oriented at an angle to the slide rail 12. The pivoting movement of the drawer 5 can be continued by the hook 23 being raised further by the adjusting device 21, as is shown in FIG. 6C, the angles here also being exaggerated to illustrate the mode of operation.

A side frame 8 of the drawer 5 is shown in FIG. 7A. In the rear loading area, the side frame 8 comprises a fastening device for fixing the rear wall 7, which has a fastening projection 31 which can be connected to a holder mounted on the rear wall 7. In addition, covers 80 and 82 are fixed to the fastening device from a metal sheet. The fastening device also has an adjusting device 30 with an adjusting element 36, by means of which the height position of the side frame 8 can be adjusted relative to a drawer rail 12. By turning the setting element 36, the side frame 8 in the rear area of the drawer 5 can be raised or lowered to adjust the inclination of the front panel 6.

The cover 80 of the side frame 8 comprises a bent edge 81, in which an opening 84 is provided, into which a projection 35 of a Fixierele element 34 can be inserted. The cover 82 comprises a bent edge 83 in the upper region, which is penetrated by projections 32 of the fastening device 30. Other fastening mechanisms for fixing the covers 80 and 82 can also be provided. The bending edges of the covers gen 80 and 82 extend parallel to the longitudinal direction of the side frame 8. FIG. 7B shows a detailed view through the rear region of the side frame 8 in an assembled position, and it can be seen that the fastening device with the adjusting device 30 between the covers 80 and 82 is received in a hollow chamber.

A front end of the covers 80 and 82 is arranged in a lower position on the adjusting device at an angle to the normal to the longitudinal direction, preferably in an angle range between 0.1 ° to 2 °. As a result, a front panel 6 resting against the end face can be adjusted by the adjustment device from a position parallel to the normal to the longitudinal direction of the side frame 8 in opposite directions in inclination.

In Figure 8, the drawer 5 is shown in an area adjacent to the rear wall 7, in which the adjusting device 21 shown schematically in Figures 6A to 6C is provided for adjusting the height of the drawer 5 in the rearward area. Unlike in FIG. 7, the adjusting device 21 is not arranged in the side frame 8, but rather outside, and comprises a guide 60, which is fixed on the drawer rail 12 and on which a slide 62 is held biased by a spring 61. The slide 62 has an expandable hook 63 which engages in an opening in the rear wall 7 of the drawer or in an adjusting device in the rear wall 7. A spreading element 64, which is arranged on a holder 65, serves to spread the hook 63. The holder 65 comprises a threaded bolt 66 with a knurled delnut 67, which are adjustably mounted on a holder 40. The holder 40 comprises two webs 41, between which the knurled nut 67 is axially immovable but rotatably arranged to adjust the holder 65 in the lateral direction. This allows the spreading element 64 to move the spreadable hook 63 in the lateral direction.

In addition, the adjustment device comprises a device for height adjustment with a vertical threaded rod 50 which can be rotated via a knurled nut 51. The knurled nut 51 is arranged in a receptacle 52 of a base element 53 supported on the drawer rail 12. On the base member 53, a slide 54 is guided in the vertical direction, which is coupled to the adjusting element 40 via connecting elements 55. The slide 54 can be adjusted with the adjusting element 40 by turning the knurled nut 51 in the vertical direction, since the threaded rod 50 engages in a threaded bore 56 of the slide 54. This allows a continuous adjustment of the Make drawer 5 in the rear area. When the slide 54 is raised, the adjusting element 40 is also raised, which engages under two floors 43 of a drawer 5, which is then no longer supported on the drawer rail 12 when lifting, but on the arms 43. The adjusting device can thus be designed as disclosed in DE 10 2015 106 789 A1. Other mechanisms for height adjustment can also be used on the drawer rail 12 in order to align the front panel 6 accordingly.
