Definitions

• the present invention relates to a drawer guide rail having a support rail which can be fixed to a furniture carcass and a running rail which can be connected to a drawer.
• Drawer guide rails of the aforementioned kind are known in many embodiments, even those in which between the mounting rail and the
• the known drawer guide rails are hitherto horizontally duri fend and with respect to this horizontal mounting arrangement not changeable installed in appropriate furniture.
• Drawers are generally opened by hand and also moved back into the closed position, recent developments in furniture but have also created constructions in which a drawer can be automatically extended at least in the opening direction. For this purpose, more or less expensive drive devices are required so far.
• the present invention has for its object to show a drawer guide rail, the at least one automatic opening of a
• the retaining rail is pivotally mounted about a horizontal axis on a furniture body and supported at a distance from the axis on a height adjustment or connected to a height adjustment, by means of which the support rail and thus the entire guide rail at least in a sloping towards the carcass front sloping position is tilted. If such drawer guide rails used for a drawer, the drawer can be opened automatically by inclining the drawer slide rails, here the principle of the inclined plane is used.
• the drawer guide rail can be tilted downwardly in the direction of the rear of the cabinet via the height adjustment device, it is also possible to automate the closing movement of a drawer.
• the height adjustment can also consist of a horizontally adjustable and the support rail supporting wedge, in which case only the wedge in the horizontal direction on relatively simple drive means must be displaced.
• Figure 1 is a highly schematic side view of a slidably mounted in a furniture body drawer with a drawer guide rail according to the invention
• Figures 2-8 perspective and highly schematic representations of guide rails according to the invention according to various exemplary embodiments of the invention
• Figure 10 is a highly schematic arrangement shown for synchronizing the adjustment of two mutually parallel drawer guide rails.
• reference numeral 1 denotes a partial section of a furniture carcass, in which a drawer 2 is slidably guided via left and right side mounted drawer guide rails 3.
• Each of the drawer guide rails comprises a mounting rail 3a which can be fixed to the furniture body 1 and a running rail 3b which can be connected to the drawer 2; if appropriate, also center rails 3c which extend from the mounting rail 3a and the running rail 3b can also be provided, as indicated in FIGS.
• the respective support rail 3a is pivotally mounted about a horizontal axis 4 on the furniture body 1 and at a distance from the axis 4 with a height adjustment device 5 coupled or connected such that the support rail 3a and thus the entire drawer guide rail 3 to the horizontal Axis 4 in a direction of the body front side Ia is tilted, and this is shown in Figure 1 for clarity in an exaggerated view.
• the support rail 3 a may be connected to the height adjustment device 5 or supported by this.
• the drawer 2 is either automatically opened by gravity or automatically returned to the closed position from an open position.
• the drawer guide rails 3 can be equipped with known end stop dampers.
• the drawer guide rail 3 is provided in its front, the body front side Ia adjacent end face with a bearing bore 4a having a bearing 4b, wherein in the bearing bore 4a a body side mounted, not shown bearing pin can engage.
• a body side mounted, not shown bearing pin can engage.
• Drawer guide rail 3 in a simple manner about a horizontal axis 4 pivotally mounted on the furniture body 1.
• the height adjustment device 5 can be realized structurally in a variety of ways.
• FIGS. 2-8 indicate different possibilities here.
• the support rail 3 a mounted on the body side and thus the entire drawer guide rail 3 is supported on the piston rod 6 a of a lifting piston 6 in its rear end region facing away from the bearing 4 b, the lifting piston 6 being fixed to the furniture body 1.
• the piston rod 6a By extending or retracting the piston rod 6a, the rear end of the drawer guide rail 3 - based on the horizontal position of the bearing 4b
• a rack 7 is attached to raise or lower the corresponding rear end portion of a drawer guide rail 3 on the carcass side mounted mounting rail 7, which meshes with a furniture body side mounted pinion 7a, which in turn is driven by an electric motor.
• a rotation or lowering of the rear end portion of a drawer guide rail 3 is achieved by rotation of the pinion 7a.
• This function of raising or lowering can also be achieved in that - as shown in Figure 4 - the furniture body side mounted mounting rail 3a is supported on a wedge 8, which is displaceable in the horizontal direction via an electric motor 8a.
• a pivoting movement of the drawer guide rail 3 about the horizontal axis 4 can also be achieved in that the support rail 3 a on a
• Bimetallic plate 9 is supported, which can be heated via a symbolically illustrated heating unit 9a.
• FIG. 6 A further possibility for the construction of a height adjustment device 5 is shown in FIG 6. It is clear that here an electrically driven, body side fixed spindle 9 is provided in a corresponding spindle thread provided, connected to the support rail 3 a and acting as a spindle nut plate 9a intervenes.
• a height adjustment device 5 is realized in which on the support rail 3a, a guide pin 10 is fixed, which engages in a curve or slotted guide 10a of a motor horizontally displaceable sliding block 10b.
• the height adjustment device 5 according to the exemplary embodiment of Figure 8 consists of a rotatably driven control cam 11, on which the bearing 4b remote from the rear end of the support rail 3a is supported.
• FIG. 9 shows an alternative to the exemplary embodiment according to FIG.
• Curve or slide guide 10a shown. It is clear that here the sliding block 10b rests in the neutral position of the drawer, so in its inserted state, on a central, horizontally extending portion of the cam or slide guide 10a.
• the two end sections of the cam or cam guide 10a run obliquely downwardly sloping or rising obliquely upwards to this central section, so that it is readily possible for a drawer guide rail to be both toward the front of a furniture carcass or towards its rear side To bring inclination.
• Figure 10 is representatively shown that the drawer guide rails 3 of a drawer, which are known to be arranged on the left and right sides of a drawer, can be adjusted via synchronized mechanisms.
• a wedge 8 is used to raise or lower a drawer guide rail 3.
• FIG. 10 clearly shows that the two wedges 8, which are required for a left-hand and a right-hand drawer guide rail 3, are coupled to one another by a crossbeam 8b so that both drawer guide rails 3 of a drawer are raised and lowered only by means of a drive and that this movement of raising or lowering is synchronized.
• the advantage of the arrangement according to the invention is that the entire system of adjustment and displacement of the drawer is independent of its loading condition, since in principle requires larger forces for pushing out or retraction of the drawer at high loading weight However, these larger forces are also incurred automatically so to speak, since the drawer is opened or closed to a certain extent on an inclined plane.
• the entire system is basically self-adjusting.
• the activation of the respective height adjustment device 5 can take place in a manner not shown via corresponding activators or switches, which react, for example, to a touch on the drawer 2 or by direct contact or approach.
