Abstract
Description
[0001] The present invention relates to a pull-out system for installation in a furniture carcass, comprising a linear pull-out, which includes a support element and a left and a right guide element for guiding the support element.
[0002] Drawer systems are known in which guide elements are arranged on the side walls of a furniture carcass and connected to it. In known furniture drawer systems, a front panel of the furniture is part of the drawer mechanism.
[0003] The object of the invention is to create a pull-out system for installation in a furniture carcass that enables a particularly compact design, in which, in addition to the furniture pull-out, space is still available in the furniture carcass for, for example, a water purifier.
[0004] This problem is solved according to the invention by a pull-out system for installation in a furniture carcass, comprising a linear pull-out and at least one first frame wall, wherein the linear pull-out comprises a support element and a left and a right guide element for guiding the support element, wherein the first frame wall is to be placed on a base of the furniture carcass, parallel to the pull-out direction of the linear pull-out, spaced apart from the carcass side walls, wherein one of the guide elements is connectable to the first frame wall, and wherein in at least one of the front and rear end regions of the first frame wall the first frame wall comprises a side panel extending at right angles to the pull-out direction of the linear pull-out, which at its lower end transitions into a side panel support region angled at right angles inwards for supporting the side panel on the base.
[0005] The first frame wall can thus form a lateral closure of the drawer system. Due to the side panel extending at right angles to the extension direction of the linear drawer and the side panel support area angled inwards from the side panel, the frame wall allows for a stable placement on the base of the furniture carcass, secured against lateral tilting or twisting / bending.
[0006] The side panel stiffens the first frame wall. This ensures that the linear extension can be stably supported, even when the support element is loaded with heavy containers, and even when the extension system is cantilevered with a first and second frame wall. The side panel can rest directly on the base of the furniture carcass, or it can rest indirectly on the base of the furniture carcass, for example, via a base support area on a side of the first frame wall. The side support area can be connected to the base of the furniture carcass. For example, if the first frame wall is made of sheet metal, the side panel and the inwardly angled side support area can each be formed by folding or bending the sheet metal.For example, in the case of a first frame wall manufactured as a molded plastic part, the frame wall, including the side panel and side panel support area, can be formed in one piece from plastic. Directions perpendicular to the extension direction of the linear slide can also be described as directions perpendicular to the main surface of the first frame wall.
[0007] The other guide element can be connected to a side panel of the furniture carcass and / or a second frame panel of the drawer system. For example, the drawer system might only include one (the first) frame panel on one side, and the other guide element could be connected to a side panel of the furniture carcass. This other guide element could be connected directly to the side panel of the furniture carcass or via a spacer, such as a spacer strip. Alternatively, the drawer system could include the first frame panel and a second frame panel, with both frame panels positioned at a distance from the side panels of the furniture carcass and resting on the base of the carcass. This allows the drawer system to be installed freestanding within a furniture carcass.
[0008] Advantageous embodiments are specified below and in the dependent claims.
[0009] The pull-out system can be specifically designed for installation in a furniture carcass behind a cabinet door. The linear pull-out can, for example, include a front panel for placement behind a cabinet door.
[0010] The first frame wall can, in particular, form a side panel of the drawer system. The guide element, which can be connected to the first frame wall, is designed to guide the support element along the first frame wall. The support element is held extendable by the left and right guide elements, for example, along the first frame wall and a side panel of the furniture carcass, or along the first frame wall and a second frame wall of the drawer system. The guide elements are connected to the support element.
[0011] Preferably, the cheek extending perpendicular to the extension direction of the linear extension is firmly connected perpendicularly to the cheek support area.
[0012] The frame wall can also be described as the side panel of the pull-out system.
[0013] In preferred embodiments, the first frame wall transitions at its lower end, between its front and rear end regions, into a bottom support area angled inwards at a right angle for supporting the first frame wall from the ground. This increases the dimensional stability of the first frame wall.
[0014] For example, the first frame wall can be made of sheet metal, with the cheek being designed as a right-angled folded section, and with the cheek support section being designed as a further folded section that is right-angled from the cheek.
[0015] The cheek support area or the respective cheek support area can, for example, overlap at least partially with the floor support area.
[0016] For example, the first frame wall can be made of sheet metal, and the bottom support area can be designed as a right-angled, folded lower section. Alternatively, the first frame wall can be made of molded plastic, and the side support area, or each side support area, can be designed as a single (common) surface element together with the bottom support area. For example, the side support area, or each side support area, can be identical to the bottom support area.
[0017] Preferably, the first frame wall is firmly connected at right angles to the floor support area between its front and rear end regions at its lower end.
[0018] In certain embodiments, the side support area and / or the base support area (if present) has at least one respective fastening recess for force-fit connection of the first frame wall to the base of the furniture carcass. The fastening recess can, for example, be designed for screwing the first frame wall to the base of the furniture carcass. The side support area and / or the base support area can thus be firmly connected to the base of the furniture carcass, e.g., by screwing.
[0019] In embodiments, the side support area has a fastening recess for force-fit connection of the first frame wall to the base of the first furniture carcass, and the base support area has at least one fastening recess overlapping with the fastening recess of the side support area for force-fit connection of the first frame wall to the base of the furniture carcass. The overlapping fastening recesses enable a particularly torsionally rigid fastening of the first frame wall to the base of the furniture carcass.
[0020] In embodiments, the first frame wall comprises a cheek extending perpendicular to the extension direction of the linear extension in both its front and rear end regions. At its lower end, this cheek transitions into a cheek support area angled inwards at a right angle to the floor. In particular, a front half of the first frame wall can be mirror-symmetrical to a rear half. This is especially advantageous because the first frame wall can then be selectively arranged on either the left or right side of the linear extension and, accordingly, can be selectively connected to either the left or the right guide element. The first frame wall is then symmetrical with respect to a vertical median plane of the first frame wall.In an embodiment with the first frame wall and the second frame wall, the second frame wall is preferably designed or shaped in the same or identical way to the first frame wall.
[0021] In some embodiments, the extension system includes a top cover designed to rest against the first frame wall. The cover can, for example, be a cover for the linear extension. The top cover can be made of, for example, plastic and / or metal.
[0022] In some embodiments, the first frame wall includes a horizontally extending headrest area in its upper edge region for supporting the upper cover. The headrest area can, for example, be angled inwards at a right angle. In the case of a first frame wall made of sheet metal, the headrest area can be formed, for example, by bending the frame wall.
[0023] In some embodiments, the headrest area includes at least one locking contour for frictionally and / or positively locking the cover against displacement in the extension direction of the linear extension. The upper cover can, for example, be designed to be detachably placed on the first frame wall.
[0024] In some embodiments, the support element has at least one recess into which a container with outwardly projecting upper edges can be inserted. The recess is an opening and has a substantially rectangular cross-section. The containers can be, for example, collection containers, in particular laundry baskets or waste containers, or the like.
[0025] The guide element can, in particular, comprise a stationary rail and a rail that moves with the support element. The linear extension can comprise a left and a right side panel, to which the support element is attached by the guide elements. The support element can be a suspension frame that has at least one recess. The support element can be designed as a drawer. The support element can include the side panels.
[0026] The side panel can be multi-part and can have a side panel section (e.g., in the form of a fold in the frame wall) at a height where the relevant guide element can be connected to the first frame wall. The side panel section or fold can cover part of the guide element from the front. A lower part of the first frame wall, where the side panel or the lower part of the side panel attaches, can have a reduced length (in the extension direction) compared to an upper part of the first frame wall, where the relevant guide element can be connected to the frame wall. This allows for a compact design while simultaneously providing good lateral coverage of the guide element. The first frame wall can be designed to cover the relevant guide element laterally, particularly along its entire length when retracted.
[0027] The following are examples of implementation explained in more detail with reference to the drawings. They show: Fig. 1a a side view of a frame wall of the pull-out system according to an embodiment; Fig. 1b a top view of the frame wall according to the embodiment; Fig. 2 a perspective side view of the frame wall according to the embodiment; Fig. 3 a perspective side view of a pull-out system with a cover according to one embodiment; Fig. 4 a perspective side view of a pull-out system with two frame walls and a cover according to one embodiment.
