Description

[0001] The invention relates to a drawer according to the preamble of claim 1 and to a piece of furniture equipped therewith, in particular a cabinet according to the preamble of claim 8.

[0002] A drawer is an open container, usually supported at the top by side-mounted rail guides, which can be pulled horizontally out of a piece of furniture, such as a cabinet.

[0003] In the simplest case, the lateral rail guidance is formed by a groove on one relatively movable part, for example the drawer, and a spring engaging in the groove on the other relatively movable part, for example the piece of furniture.

[0004] Today, drawers are predominantly equipped with so-called telescopic slides, which make opening and closing the drawers easier due to reduced friction compared to a tongue-and-groove guide. These slides consist of at least two guide rails whose profiles run within each other. The profiles can slide against each other, or rolling elements can be arranged between them. Telescopic slides can be designed as either rolling or sliding guides. They can be configured for partial, full, or over-extension. Furthermore, they can be equipped with a quick-release mechanism that allows for the rapid separation of two sections of the telescopic slide for removing the drawer.Such telescopic rails, on which a drawer is supported laterally on both sides, whether by simply placing it on top or by hooking it in, with or without the use of fasteners, are also called telescopic supports.

[0005] German patent DE 25 56 093 A1 discloses a cabinet with drawers or compartments that are height-adjustable after being pulled out. One or more compartments of the cabinet can be lowered to an accessible height and raised back to their original position by means of a lifting device located in the side walls of the cabinet. A compartment to be lowered or raised is pulled out of the cabinet until it reaches a stop, at which point it is engaged with the lifting device. In this position, the compartment protrudes above all other compartments in the cabinet. The lifting device is then actuated, for example, by a crank mechanism, which lowers or raises the compartment engaged with the lifting device in front of the compartments remaining in the cabinet.If several compartments are pulled out simultaneously and coupled to the lifting device, they will experience a common and uniform vertical movement when the lifting device is activated.

[0006] The disadvantage of this system is that each drawer must be coupled to the lifting mechanism while being pulled out in order to be lowered or raised. This requires a complex mechanism that carries the risk of failure, potentially leading to serious injuries when handling the cabinet. Furthermore, retrofitting existing cabinets and furniture is impossible due to the central lifting mechanism, which is used uniformly for all compartments of the cabinet.

[0007] One object of the invention is the development of a height-adjustable drawer which can be retrofitted and ensures reliable and safe handling, as well as a piece of furniture equipped with such a drawer.

[0008] The problem is solved in each case by the features of the independent claims. Advantageous embodiments are described in the claims, the drawings, and the following description, including those pertaining to the drawings.

[0009] A first object of the invention therefore relates to a drawer with a rail guide on both sides.

[0010] The drawer comprises means by which a portion of the drawer comprising at least one bottom of the drawer is arranged in a variable distance to a remaining portion of the drawer, which is connected or connectable to the double-sided rail guide or at least comprises at least a part of the double-sided rail guide, normal to a plane spanned by the bottom.

[0011] The remaining portion may comprise at least one part each of two opposing side walls intended for arrangement on and / or connection with and / or reception of the double-sided rail guidance.

[0012] The rail guides are preferably formed by telescopic supports or include or are encompassed by such supports in which the drawer can be inserted.

[0013] The means may include a device formed by two X-shaped holders mounted in the side walls of the drawer, the ends of which slide in horizontal guides of the side walls and the telescopic support.

[0014] It is evident that at least the first object of the invention can be realized by a drawer with a height-adjustable, in particular lowerable, base.

[0015] The drawer, either in its entirety or just its bottom, can be lowered to an easily visible and / or accessible height after being pulled out of a cabinet, without its contents falling out.

[0016] A particularly noteworthy advantage over the state of the art is the safe handling, which is achieved by eliminating the need to couple one of several drawers to a central lifting mechanism as required.

[0017] A second aspect of the invention relates to a piece of furniture with at least one drawer that can be pulled out from it.

[0018] The piece of furniture, preferably designed as a cabinet, is characterized by at least one drawer, as described above, which is height-adjustable after being pulled out.

[0019] Additional advantages over the prior art, beyond the complete solution of the stated problem and / or the advantages mentioned in the preceding or subsequent description of the individual features, include a reliable and safe design achieved through means provided between the drawer slides and the drawer base. These means allow the portion of the drawer encompassing at least the drawer base to be lowered relative to the remaining portion after it has been pulled out. This eliminates the need for a failure-prone coupling with a lifting mechanism. Instead, each drawer where a corresponding height adjustment, particularly a lowering function, might be necessary—for example, depending on the height of a person handling the drawer and its contents—is equipped with appropriate means.The drawer can be retrofitted into existing pieces of furniture, whether due to the increasing age of the person using it, the addition of children, or a change of ownership, for example, fitted kitchens passed on as accessories to rented or sold living space, or simply because of the emerging, previously unknown possibility of lowering high-lying drawers.

[0020] The invention provides a pull-out drawer whose bottom, or the entire drawer, can be lowered to an easily visible and / or accessible height after being pulled out of a cabinet, without its contents falling out. The drawer offers improved accessibility, particularly simplified adjustment of its access height. It is safe to use and allows for retrofitting existing furniture. Furthermore, installing one or more such drawers in a piece of furniture, especially in the upper part of a piece of furniture, simplifies access to drawers located higher up.

[0021] It is evident that at least the second object of the invention can be realized by a cabinet with drawers in which the upper drawers are made accessible to the user, for example, by a device or mechanism after being pulled out, to a height accessible to the user and from there returned to their initial position. The device can be formed by two lateral, horizontally extendable telescopic supports in which the drawer can be suspended, and by two X-shaped holders received in the side walls of the drawer, the ends of which slide in horizontal guides of the side walls and the telescopic supports.

[0022] The present invention therefore takes a different, simpler approach for moving the upper drawers. It is preferably characterized in that, in contrast to the lifting device of the prior art, the device is formed by two lateral, horizontally extendable telescopic supports in which the drawer can be suspended, and by two X-shaped holders received in the side walls of the drawer, the ends of which slide in horizontal guides of the side walls and the telescopic supports.

[0023] The invention is explained in more detail below with reference to exemplary embodiments shown in the drawing. The relative sizes of the individual elements in the figures do not always correspond to their actual sizes, as some shapes are simplified and others are enlarged for clarity in relation to other elements. Identical reference numerals are used for identical or equivalently functioning elements of the invention. Furthermore, for the sake of clarity, only those reference numerals necessary for describing the respective figure are shown in the individual figures. The illustrated embodiments merely represent examples of how the invention can be implemented and do not constitute an exhaustive limitation.
