Description

The invention relates to a rail system for guiding the extension, in particular for underfloor guidance, of a drawer, comprising a cabinet rail for mounting on a furniture carcass, a drawer rail for mounting on a drawer, and a front adapter for the direct or indirect attachment of a drawer front to the drawer rail, wherein the drawer rail is axially movable relative to the cabinet rail and can be moved along an extension direction from a retracted position to an extended position. Further aspects of the invention include a piece of furniture with a furniture carcass and at least one drawer, as well as methods for adjusting the axial position of a drawer front of a drawer of a piece of furniture, in particular for converting from a front extension to an internal extension or from an internal extension to a front extension. The invention is used in a rail system for guiding the extension of a drawer, enabling the drawer to be pulled out of a piece of furniture. For this purpose, such rail systems comprise a cabinet rail and a drawer rail. The cabinet rail is used to mount the rail system to the cabinet body of the furniture, while the drawer rail is mounted to the drawer itself. To allow the drawer to be pulled out using the rail system located between the drawer and the cabinet body, the drawer slide is mounted to allow axial movement relative to the cabinet rail. This allows the drawer slide, along with the drawer, to move from a retracted position, in which the drawer slide cannot be moved further axially towards the cabinet rail, to an extended position, in which the drawer slide is moved axially away from the cabinet rail. In the extended position, the interior of the drawer, connected to the drawer slide, is accessible from the outside. A drawer typically consists of a drawer bottom, two opposing side drawer sides, a drawer back, and a drawer front. To mount the drawer to the drawer runner of the rail system, the runner has a front adapter. When mounted, this adapter is located at the end of the drawer runner facing the drawer front, i.e., the end furthest from the cabinet runner. The drawer, including the drawer front, is attached to this front adapter. This can be done indirectly, for example, via a locking clip mounted on the drawer, which engages the front adapter to secure the drawer to the rail system, as is the case with a solid wood drawer. Alternatively, a direct attachment is possible, as with a box drawer. In this case, with an undermount runner, the drawer runner is not attached to the outside or top of one of the drawer sides, but rather to the underside of the drawer or to the inside of the side that extends downwards beyond the drawer bottom. Furthermore, a pin may be provided on the drawer runner or the front adapter, which engages with the underside of a side panel or elsewhere in the drawer. During the installation of the rail system and the drawer, inaccuracies can occur, resulting in the drawer being either inserted too deeply or not deeply enough into the furniture. The drawer front may then be positioned so flush against the furniture carcass that the drawer rail cannot reach its fully retracted position, or it may protrude too far from the furniture carcass, causing it to be incorrectly positioned relative to the fronts of other drawers or doors in the furniture. In particular, it may protrude too far or be inserted too deeply into the carcass. Depth adjustment is necessary to compensate for such installation inaccuracies once the furniture is assembled. The drawers known to date provide for this purpose by allowing the drawer's position relative to the rail system to be changed. In addition to lateral and height adjustment mechanisms, the locking clips of such drawers have a depth adjustment mechanism that allows the drawer's relative position to be set in relation to the drawer rail. Such depth adjustment devices have proven disadvantageous because they require the use of locking clips. Due to their design, these cannot be used with box drawers, which have thin-walled sides made of thin sheet metal and separately mountable and dismountable drawer fronts. Since the drawer front of such box drawers is attached to the drawer slide, changing the position of the drawer, and especially the drawer front, relative to the slide system using a locking clip is impossible anyway. The object of the present invention is therefore to specify a depth setting which which can be used in the same way for solid wood drawers and box drawers. This task is solved in a device of the type mentioned above by the fact that the front adapter has a depth adjustment element for setting an axial distance of the front adapter to the cabinet rail in the retracted position. The depth adjustment element allows the axial distance of the front adapter to the cabinet rail to be adjusted in the retracted position, without requiring any change to the drawer's position relative to the drawer runner. The axial distance
