The present invention relates to a pull-out guide for a drawer, comprising a carcass rail configured to be arranged on a side of a furniture carcass, and a drawer rail configured to be arranged on a drawer, the drawer rail being displaceably supported on the carcass rail in an opening- and closing direction. The drawer rail has an upper side facing towards the drawer and a lower side spaced from the upper side by at least one side limb. The pull-out guide further comprises a bearing device for a synchronization rod of a synchronization device, the bearing device including a fastening region for the synchronization rod. Moreover, the invention concerns an arrangement comprising two such pull-out guides, and an item of furniture comprising a drawer and an arrangement of the mentioned type.
In order to move movable furniture parts, in particular drawers, relative to a furniture carcass, the movable furniture parts are usually movably supported in an opening- and closing direction via pull-out guides, the pull-out guides comprising a carcass rail and a drawer rail. With such furniture fittings, synchronization devices are frequently provided so as to allow a smooth opening and closing on both sides, and helping to prevent an inclination, and, therewith, a jamming of the drawer.
An example for such a furniture fitting is disclosed in EP 3 282 895 B1. A drawback with this furniture fitting is the fact that the drive devices in the form of ejection devices arranged on both sides are relatively broad and take up much space.
Therefore, the object of the present invention is to provide an alternative or an improved arrangement, respectively, with respect to the prior art. In particular, the space requirement shall be as small as possible.
This is accomplished by a pull-out guide in which the fastening region (preferably extending horizontally in the installation position), is arranged below the underside of the drawer rail.
Therefore, it is possible for the synchronization rod to span the drawer rail. This, in turn, results in that possibly provided drive devices can be arranged between the drawer rail and the furniture carcass.
The terms “horizontal”, “vertical”, “upper side” and “underside” always refer to the installed condition of the pull-out guide and of the furniture fitting, respectively, in the furniture carcass.
According to a preferred embodiment, the fastening region is arranged between the drawer rail and the carcass rail. Therefore, a possibly provided drive device can be arranged between these two rails, for which reason the entire unit can be configured very narrow. This means that the maximum width, measured in a horizontal direction and perpendicular to the opening direction, of the pull-out guide including the carcass rail, the drawer rail, the bearing device and a possibly provided drive device is less than 100 mm, preferably less than 75 mm. It can be particularly preferred that this width lies in a region between 40 mm and 70 mm.
In order to provide a transmission of movement from the synchronization rod to further components, the fastening region can be that region in which the synchronization rod contacts the bearing device.
The bearing device has to be configured such that the synchronization rod can be supported thereon and can be fixed in the fastening region. Preferably, the bearing device includes a carrier arranged on the carcass rail or on the drawer rail, and a receiving portion for the synchronization rod, the receiving portion being movably, preferably pivotally, supported on the carrier.
When the receiving portion is pivotally supported, preferably the rotational axis extends in a horizontal direction and perpendicular to the opening direction of the drawer.
The synchronization rod can be configured to be connected to the bearing device, for example, via a snap-connection device. Likewise, also other releasable connection variants are possible. In fact, it is possible that the fastening region is configured in the form of a protrusion on which the synchronization rod can be fixed. However, it is particularly preferred that the fastening region is configured as a recess in the receiving portion.
Protection is also sought for an arrangement comprising two pull-out guides according to the invention, the pull-out guides being configured to be mounted to opposing sides of a furniture carcass.
It is particularly preferred that this arrangement, besides the two pull-out guides, also includes a synchronization device including a synchronization rod for synchronizing movements of the drawer rail or of movements of possibly provided drive devices.
Further, it is preferable that the synchronization rod has two ends, and is supported via their ends in the fastening regions of the bearing devices, the synchronization rod extending below the drawer rails. This means that the synchronization rod does not extend between the drawer rails or above the drawer rails, but rather entirely below these drawer rails. Thereby, it can be particularly preferred that the synchronization rod is aligned horizontally in the installed condition and entirely extends vertically below the drawer rails in the installed position.
It is particularly preferred that the arrangement also includes at least one drive device for the drawer, the at least one drive device being preferably mounted to one of the carcass rails. Preferably, the arrangement includes two drive devices (each mounted to one of the carcass rails) for the drawer.
It is possible that at least one drive device is configured as a retraction device configured to retract the drawer from an open position into the closed position. However, according to a preferred embodiment, the at least one drive device is configured as an ejection device for ejecting the drawer. The ejection device is configured to be unlocked by applying pressure to the drawer when located in the closed position, and the drawer can be moved from the closed position in the opening direction and can be brought into an open position by the unlocked ejection device.
According to a specific embodiment, it is preferable that the at least one drive device configured as an ejection device includes a housing, an ejection slider movably supported in the housing, an ejection energy storage member fixed to the housing and to the ejection slider, a heart-shaped guide track formed in the housing, a locking pin configured to be locked in a locking recess of the guide track, and a control lever movably supported on the ejection slider, the control lever having the locking pin.
For the sake of a simple and space-saving construction, it is preferable that the housing forms the carrier of the bearing device. Accordingly, the receiving portion of the bearing device is movably supported directly in the housing.
For a simple transmission of movement between the synchronization rod and the drive device, it is preferable that a coupling element is formed or arranged on the receiving portion. The coupling element is preferably gear-shaped and is configured to be coupled in a movement-transmitting manner to a coupling element, preferably shaped as a toothed rack. It is particularly preferred that the coupling element is arranged or formed on a synchronization slider movably supported, preferably linearly, on the housing.
The precise alignment and position of the synchronization rod is, in fact, arbitrary, as long as a synchronized transmission of movement between both sides of the pull-out guide can be provided. It is preferable that the synchronization rod (in an installed condition) is aligned horizontally and perpendicularly to the opening- and closing direction.
Protection is also sought for an item of furniture comprising a furniture carcass, at least one drawer (movable in the opening direction), and an arrangement of the described type.
Further details and advantages of the present invention will be described in more detail in the following with the aid of the description of figures and with reference to the embodiments shown in the drawings, in which:
With the uppermost drawer 2, a drive device 1 is schematically depicted. The drive device 1 includes a housing 3. In this case, this housing 3 is arranged on the drawer rail 13 (in the schematic illustration according to
When the drawer 2 is moved from the open position OS in the closing direction SR, the locking pin 51 is displaced in a closing section of the guide track 52. Thereby, the ejection storage member 42 can be tensioned by a relative movement between the ejection slider 41 and the housing 3.
In the closed position SS (third drawer 2 from above), the ejection energy storage member 42 is fully tensioned. This closed position SS can be achieved by an exclusive manual closing movement. Alternatively, the drawer 2 can be moved or retracted into the closed position SS by the schematically depicted retraction device 16. The retraction device 16, if present, is integrated into the pull-out guide 20.
Starting from that closed position SS, the drawer 2 reaches an overpressing position US (lowest drawer 2 in
With broader or larger drawers 2, respectively, it can be advantageous, in particular for preventing inclined positions or jamming of the drawer 2 within the furniture carcass 9, when drive devices 1, 1′ are provided on both sides of the drawer 2, the drive devices 1 and 1′ being synchronized with one another.

However, it is also equally possible that the synchronization device 6 only serves for synchronizing the movement of the two drawer rails 13. This corresponds to a so-called side-stabilization.
