Description

[0001] The present invention relates to a drawer with an ejection device, wherein the drawer is displaceably mounted via two pull-out guides and each pull-out guide comprises a guide rail which can be fixed to a furniture carcass and a running rail on which the drawer is supported, wherein at least one pull-out-extending central rail can optionally be provided between the guide rail and the running rail, and the drawer has a base which is held laterally on at least one angled frame adapter, and the ejection device is held on a support.

[0002] DE 20 2011 108 293 U1 discloses a device for opening and closing a movable furniture part, in which an ejection unit is attached to a movable furniture part as a preassembled assembly. Clip or locking elements can be provided for detachable fastening of the ejection unit. Such clip or locking connections have only limited stability, and there is a risk of damage.

[0003] AT 12 950 U1 discloses a drawer movable via an ejection device, having two side walls. Each side wall is connected to an adapter part, which has a support leg for supporting a drawer base. Each adapter part extends the entire length of the drawer and is supported by one leg on a container rail of a drawer guide.

[0004] It is also known to screw such pre-assembled ejection units to the bottom of a drawer. However, such screw connections require considerable assembly effort, which is particularly disadvantageous in automated production.

[0005] It is therefore an object of the present invention to provide a drawer with an ejection device which enables simple assembly of the ejection device and ensures stable fixation.

[0006] This object is achieved with a drawer having the features of claim 1.

[0007] In the drawer according to the invention, the ejection device is mounted on a support, which is positively or non-positively fixed to at least one drawer frame adapter. This allows the support to be easily mounted on the drawer frame adapter in order to fix the ejection device to the support before or afterward.

[0008] Preferably, the support can be secured to the drawer frame adapter by a sliding movement. Instead of a sliding movement, it is also possible to use a pivoting or rotating movement to secure the support to the drawer frame adapter. The sliding movement can, for example, occur parallel to the drawer's extension direction. This type of sliding movement is also suitable for automated production.

[0009] The drawer frame adapter is U-shaped and has an angled section at one end of a vertical leg. The drawer base rests on the angled section. In the transition area between the vertical leg and the angled section, the angled section has a height offset or is designed in a step-like manner. This height offset means that the drawer base can be pushed up to the vertical leg of the drawer frame adapter. The vertical leg can also be at least partially covered by a part of the frame shell so that the base rests against the frame shell. Without the height offset, the lower edge of the drawer base would rest against the bending radius between the leg and the angled cut, which would place the drawer base in an undesirable, undefined position.The height offset can be achieved by means of features on the angled section and / or by means of a corresponding contour bend in the transition area between a vertical leg of the frame adapter and the angled section.

[0010] The mounting interface for the support on the frame adapter is located in the transition area between a preferably vertical leg of the frame adapter and a section angled to it. The mounting interface is thus formed in the contour bend or in the low area between the leg and the protrusion.

[0011] For positive or non-positive fixation, one or more tabs can be molded onto the support, which are inserted into a receptacle on the frame adapter. Preferably, at least two tabs are provided on the support and two receptacles on the frame adapter, thus preventing rotation of the support relative to the frame adapter. Each tab can be fixed, preferably by clamping, between an underside of the drawer base and a receptacle of the frame adapter. Alternatively, the tabs can also be molded onto the frame adapter and inserted into receptacles on the support.

[0012] Preferably, an additional locking connection is provided on the support, which secures the positive or non-positive fixation against accidental removal. The locking connection is preferably designed as an angled web. A weakened material is located on the angled web of the support so that the locking connection can be easily released for disassembly without damaging the system.

[0013] The drawer frame adapter can be used to fix a hollow or double-walled side frame to which a pull-out guide is arranged, so that the drawer is provided in a particularly compact design.

[0014] The double-walled frame can be provided with a frame adapter extending the length of the frame or with several frame adapters arranged at intervals along the frame. The double-walled frame can consist of several individual side walls that, as a unit, form a double-walled frame.

[0015] A frame adapter is attached to the end of the frame to secure the front panel. This front panel attachment can be connected to other frame components.

[0016] In the drawer, a housing of the ejection device can also be attached to the support via the interposition of at least one elastic element in order to achieve acoustic damping of switching or impact noises and to prevent sound from being amplified via the drawer or the furniture carcass as a resonance body. The elastic element can be designed as a surface element that is arranged between a plate of the support and the housing of the ejection device. In addition, one or more pins can also be provided, around which an elastic ring is arranged, which is surrounded by an annular receptacle. In this way, damping forces can provide support in different directions of movement via the elastic elements if a plane formed by the ring is aligned parallel to the plane of the surface element.

[0017] For easy installation, the ejection device can be snapped, riveted, or screwed to the support. Gluing the ejection device to the support is also possible as an alternative or additional option.

[0018] In a method for mounting an ejection device on a drawer, a drawer frame adapter is first secured to the base of a drawer. A support for the ejection device is then positioned on the drawer frame adapter and then pivoted or pushed in to secure the support to the drawer frame adapter with a positive or non-positive fit. The support assembly concludes with the locking and securing of the support to prevent it from being pulled out. This allows an ejection device to be mounted on the drawer in just a few steps.

[0019] The invention will be explained in more detail below using several exemplary embodiments with reference to the accompanying drawings. They show: Fig. 1 is a perspective exploded view of a piece of furniture with a drawer according to the invention; Fig. 2 a bottom view of the drawer of the Fig. 1; Fig. 3 a sectioned detailed view of a side frame of the drawer of the Fig. 2; Fig. 4A and Fig. 4B two perspective views of the side frame of the drawer with ejection device; Fig. 5 a perspective view of the ejection device with a carrier; Fig. 6 a detailed view of a drive element of the ejection device of the Fig. 5; Fig. 7 and Fig. 8 two perspective exploded views of the ejection device and the carrier; Fig. 9 to 11 several views of a frame adapter during assembly of a support; Fig. 12 a perspective view of the frame adapter and the support, and Fig. 13 and Fig. 14 two views of a modified embodiment with a frame adapter and a carrier.

[0020] A piece of furniture 1 comprises a cuboid-shaped furniture body 2 on which one or more movable furniture parts, in particular drawers 3, are movably mounted.

[0021] As in the Fig. 1 and Fig. As shown in Figure 2, a drawer 3 comprises a front panel 30, a base 32, a rear wall 33, and two side frames 31. The drawer 3 is slidably mounted on two pull-out guides 4. Each pull-out guide 4 comprises a guide rail 5 that can be fixed to the furniture body 2, as well as a running rail 7 on which the drawer 3 is supported. A center rail 6 that extends the extension is provided between the guide rail 5 and the running rail 7. Pull-out guides 4 with only two rails or more than three rails can also be used. In addition, the movable furniture part can also be designed as a flap, door, or drawer element.

[0022] Adjacent to each drawer guide 4 is an ejection device 8, which has an energy storage mechanism by means of which the drawer 3 can be ejected in the opening direction when the ejection device 8 is unlocked. Unlocking is preferably achieved by pressing the drawer 3 into the furniture body 2 into an overpressure position. The tensioning of the energy storage mechanism can occur, for example, during a closing movement of the drawer 3.

[0023] In Fig. Figure 3 shows a sectional view through the side frame 31, which is hollow and on which the pull-out guide 4 is arranged. The guide rail 5 of the pull-out guide 4 is supported on one or more retaining brackets 50 that are fixed to the furniture body 2. Furthermore, a frame adapter 35 is fixed to the guide rail 7, which surrounds the guide rail 7 in a U-shape and has an angular section on the side facing the base 32, which holds the base 32. A support 20 for fixing the ejection device 8 is fixed to the angular section of the frame adapter 35. An attachment 34 is fixed to the frame adapter 35, on which the side frame 31 is supported in the upper area.

[0024] In the Fig. 4A and Fig. 4B shows the ejection device 8 with a side frame 31. The ejection device 8 is fixed to a support 20, which is directly or indirectly fixed to the frame adapter 35. The ejection device 8 comprises a drive element 10, which can be coupled to a support element 41 in order to eject the drawer upon movement of the drive element 10 relative to a guide. The support element 41 is fixed in a stationary manner to the guide rail 5 or to the furniture body 2 via a holder 40, since the ejection device 8 is fixed to the movable furniture part 3.

[0025] In the illustrated embodiment, an ejection device 8 is provided on each frame 31. To ensure that the other ejection device 8 is also unlocked when one of the two ejection devices 8 is unlocked, synchronization means 9 in the form of a rod are provided, which ensure that both ejection devices 8 are unlocked simultaneously. For this purpose, the rod can be rotated or pivoted, for example.

[0026] In Fig. 5, the ejection device 8 is shown without a frame. The drive element 10 of the ejection device 8 is movable along a guide 11, which can be designed as a slot or guide web. The ejection device 8 comprises a housing 12 surrounding an energy accumulator that acts on the drive element 10. Furthermore, a locking mechanism is provided within the housing 12 to lock the drive element 10 in a closed position against the force of the energy accumulator. The internal structure of the ejection device can be designed, for example, as described in the application DE 10 2016 113 044.

[0027] The drive element 10 is in Fig. 6 in detail. The drive element 10 is provided on a contact side with an elastic element 14 which can come into contact with the support element 41, which consists of a dimensionally stable material, for example a metal sheet. In order to reduce impact noise, the elastic element 14 is designed to be dampening, for example with a hardness between 40 and 90 Shore A. Plastic, rubber-like materials or foamed materials are used as elastic materials, whereby the thickness of the elastic material is preferably less than 1 mm. The elastic material can additionally be magnetic or magnetically conductive. On the contact side, the elastic element 14 is profiled.

[0028] On the side opposite the elastic element 14, the drive element 10 is connected to a bolt 15, which has, at least in some areas, an external thread that meshes with a knurled nut 16. This allows the position of the drive element 10 to be adjusted relative to a driver 17 in order to set the closed position of the movable furniture part 3.

[0029] In the Fig. 7 and Fig. 8, the ejection device 8 is shown in an exploded view. The housing 12 of the ejection device 8 comprises a receptacle 13 for the synchronization means 9, via which an unlocking mechanism can be switched so that two or more ejection devices 8 are unlocked simultaneously. The driver 17 with the drive element 10 can be moved along the housing 12 on a guide 11. A magnet 18 is arranged in the drive element 10, which magnet is effective when the drive element 10 comes into contact with the support element 41, in that magnetic attractive forces act between the magnet 18 and the support element 41. As a result, both tensile and compressive forces can be transmitted via the drive element 10 and the support element 41. The drive element 10 can also be designed in another way without a magnet, e.g. by means of a separable positive connection.

[0030] The housing 12 is fixed to a carrier 20, with an elastic surface element 25 or 25' being provided between the housing 12 and the carrier 20. The elastic surface element 25 or 25' can be made of a foamed material, a rubber-like material, or a soft plastic. The elastic surface element 25 can be glued in one or more strips or with other forms of a surface element to a holder 19 on the housing 12 or a plate 22 of the carrier 20. Two openings 21 are cut out in a plate 22 for receiving the housing 12, into which pins 26 on the underside of the housing 12 engage. Elastic rings 24, preferably O-rings, are applied to the pins 26, so that direct contact of the pins 26 with the opening edge of the openings 21 is avoided. Furthermore, locking webs 27 are formed on the housing 12, which interact with locking receptacles 28 on the plate 22.As a result, the housing 12 can be fixed on the plate 22 of the carrier 20 without noise from the housing 12 being transferred directly to the carrier 20, since the ring 24, the elastic surface element 25 and the locking webs 27 are sufficiently elastic to have a sound-insulating effect.

[0031] The carrier 20 further comprises a strip-shaped fastening section 23, on which two tabs 29 are formed, which protrude from the fastening section 23.

[0032] The assembly of the support 20 on the frame adapter 35 is now carried out with reference to the Fig. 9 to 11 explained in more detail: A drawer base 32 is first placed on a horizontal leg of the drawer frame adapter 35 and secured there. For this purpose, one or more teeth 36 are formed on the leg, which dig into the base 32, which is usually made of a wood-based material, on the underside. Screws or other fastening means can also be provided for securing the base. To secure the support 20, it is then positioned on the drawer frame adapter 35, with the plate 22 being arranged on the underside of the base 32 and an angled web 38 being attached to the fastening section 23 on one side of the base 32 and the drawer frame adapter 35.

[0033] As in Fig. 10, the tabs 29 are arranged on the fastening section 23 adjacent to receptacles 37 which surround a channel formed between the underside of the base 32 and the U-shaped receptacle of the frame adapter 35. After positioning the carrier 20 according to Fig. 10, the fixing can now be carried out by moving the support 20 in the longitudinal direction of the side frame 31 so that the tabs 29 engage in the receptacles 37 and are fixed there by a form-fitting or force-fitting manner. During the insertion movement, an angled web 39, which is arranged at the end of the support 20, is arranged such that it latches behind the underside of the frame adapter 35 on one end face, so that the support 20 is secured by the angled web 39 against the tabs 29 being pulled out. In a next step, the ejection device 8 can then be latched onto the plate 22 of the support 20, wherein the ejection device 8 can already be fastened to the plate 22 of the support 20.

[0034] In Fig. Figure 12 shows the support 20 with the frame adapter 35 in detail. Both the support 20 and the frame adapter 35 can be made from a bent and stamped sheet steel. An opening 45 is provided adjacent to the central receptacle 37 so that the central tab 29 can be positioned in front of the channel of the receptacle 37 during assembly. The second receptacle 37 is formed at the end of the frame adapter 35.

[0035] In the Fig. 13 and Fig. Figure 14 shows a modified drawer frame adapter 35, to which a support 20 can be mounted below a drawer base 32. Adjustment means 46 are provided on the drawer frame adapter 35 for adjusting the height, depth, and / or sideways position of a front panel 30 of the drawer 3.

[0036] In the illustrated embodiment, the support 20 is mounted using two tabs 29 that are inserted into receptacles 37 on the frame adapter 35. It is, of course, also possible to form one or more receptacles on the support 20, into which tabs on the frame adapter are then inserted. Furthermore, the mounting direction can be changed. Instead of mounting by a sliding movement in the longitudinal direction of the drawer guide 4, mounting can also be performed in a different direction or by a pivoting movement.
