Description

[0001] The invention relates to a front pull-out drawer for a piece of furniture, in particular for a sink base cabinet, wherein the front pull-out drawer comprises a drawer frame with a support frame having at least one receptacle for a waste bin, and wherein the drawer frame has two parallel and spaced-apart linear guides designed to be mounted on opposite outer walls of a furniture carcass. The drawer frame is adjustable relative to the furniture carcass between a position extended from the furniture carcass and a position retracted into the furniture carcass via the linear guides. Such a front pull-out drawer is known, for example, from US20240141631A1. Similar front pull-out drawers are also described in WO2022233746A1, DE 10 2016 118 381 A1, and DE 20 2014 102 726 U1.

[0002] In the furniture industry, particularly in kitchen cabinet design, it is common to integrate drawer systems that utilize storage space efficiently. Well-known systems typically include drawers with fixed frames and standardized dimensions, attached to the interior walls of the cabinet body. These drawers are often equipped with runners that allow for full or partial opening to facilitate access to the contents. However, a frequent problem with these systems is their limited flexibility in adapting to different kitchen appliances or specific user requirements. Conventional drawer systems reach their limits, especially in sink base cabinets, where space is often restricted by pipes and other installations.

[0003] According to established approaches, drawers are typically designed to fill all available space within the cabinet body. This severely limits the space available for installing additional kitchen appliances, such as water purification systems or waste separation systems. Some systems attempt to address this issue by offering modular units, but these are often complicated to install and lack the desired stability and functionality. Despite significant advancements in furniture design, there remains a need for innovative solutions that allow for better integration of kitchen appliances within cabinets without compromising storage space.

[0004] The front pull-out mechanisms known from the prior art therefore have the disadvantage that they are either unsuitable for the integration of a kitchen appliance, preferably a water treatment device, or at least destabilize the front pull-out mechanism, thereby worsening the ergonomics of the front pull-out mechanism.

[0005] The object of the invention is therefore to provide a front pull-out which enables the integration of a kitchen appliance, preferably a water treatment device, without destabilizing the front pull-out.

[0006] This problem is solved by a front pull-out mechanism with the features of claim 1. Dependent claim 8 relates to a corresponding piece of furniture. Advantageous embodiments are the subject of the respective dependent claims.

[0007] The following description details advantageous embodiments of the invention that go beyond those specified in the claims. Although the individual features of these embodiments are disclosed in the following description in a contextual manner for better understanding, these features may also be suitable for realizing advantageous embodiments of the invention independently of one another and should therefore be understood as being disclosed independently of one another.

[0008] According to the invention, the drawer frame has a recess for a kitchen appliance, preferably a water purification device, in an area between the parallel linear guides. This recess is open in the adjustment direction of the linear guides. Preferably, the recess is open on a side facing a furniture carcass to which the drawer frame is mounted, when the drawer frame is in an extended position. The recess can be arranged in the area enclosed by the two parallel and spaced-apart linear guides.If the recess is positioned between the parallel linear guides, the center of gravity of a furniture front mounted on the front extension can also be positioned between the linear guides, effectively preventing the front extension from twisting in a vertical plane perpendicular to the adjustment direction of the linear guides, thus increasing the stability of the drawer frame and improving the ergonomics of the front extension.

[0009] The linear guides ensure stable and smooth movement of the drawer unit by being attached to the opposite outer walls of the furniture carcass. The drawer unit's support frame provides the necessary stability and supports the vertical furniture front. The recess in the drawer unit creates space for a kitchen appliance without compromising the stability of the drawer's pull-out mechanism.

[0010] One advantage of this arrangement is the increased ergonomics of the front extension, as it prevents misalignment when adjusting the front extension.

[0011] A linear guide can have two main components: a guide rail and a guide carriage. The guide rail can be fixed, for example, to one of two opposing outer walls of a furniture carcass, and forms a track along which the guide carriage can move. The guide carriage is equipped with bearings, such as rollers, that run on the guide rail, thus enabling smooth and stable movement. The guide carriage can be mounted on the drawer frame.

[0012] The support frame has an end-face rail for mounting and / or supporting a vertical furniture front, the rail extending between the opposing linear guides, and the drawer frame being open on one side spaced parallel to the rail. The end face of the rail can be prepared for mounting the furniture front. For this purpose, the end-face rail can, for example, have mounting receptacles for fasteners, such as holes for screws. The end-face rail can be directly connected to the opposing linear guides, preferably joined to them. The end-face rail can be connected to the linear guides at its opposite longitudinal ends at a 90° angle. Preferably, the end-face rail and the linear guides form a U-shape.

[0013] The recess can be bounded by the end rail, one of the linear guides, and the support frame. The end rail, the linear guide, and the support frame can preferably be arranged in the same plane, for example, in the plane defined by the linear guide and the rail.

[0014] The end rail, the linear guide, and the support frame can be arranged in a U-shape and preferably merge seamlessly into one another. The end rail can connect the linear guide and the support frame. The recess can be open on the open side of the U-shape.

[0015] The recess can extend across the entire depth of the drawer frame in the adjustment direction of the linear guides. In particular, it can reach as far as the end rail.

[0016] The support frame can have a strut that defines the recess and preferably extends in the adjustment direction of the linear guides. The strut can include a stiffening element, which is particularly preferably designed for mounting and / or support on a vertical furniture front.

[0017] According to another aspect of the invention, a piece of furniture is described, in particular a sink base cabinet, which has a front pull-out drawer of the type described above. The drawer frame can be mounted, preferably screwed, to opposite outer walls of a furniture carcass by means of its linear guides. An end face of the drawer frame facing away from the furniture carcass can be designed for mounting a furniture front.

[0018] The front pull-out mechanism can be moved back and forth relative to a kitchen appliance, preferably a water purification unit, located within the cabinet, in the depth direction of the cabinet between an extended position and a retracted position. In particular, the kitchen appliance, for example a water purification unit, can be standing or suspended within the cabinet. The kitchen appliance can be a static appliance within the cabinet, and preferably standing or suspended within it.

[0019] The kitchen appliance, in its extended position, can be positioned at least partially in front of the recess in the adjustment direction of the linear guides, and, in its retracted position, can be received at least further in the recess compared to the extended position, and preferably be completely received therein.

[0020] The support frame can extend in the adjustment direction from an end-face rail for mounting and / or supporting a vertical furniture front of the furniture, preferably over no more than 80% of the depth of the furniture body in the adjustment direction and particularly preferably over no more than 60% of the depth of the furniture body in the adjustment direction.

[0021] Further details of the invention are explained with reference to the figures below. These show: Fig. 1. An exemplary embodiment of a frontal extension in perspective view; Fig. 2 a top view of an exemplary embodiment of a front pull-out; Fig. 3 a perspective rear view of an embodiment of a frontal extension; Fig. 4 A top view of a front pull-out built into a furniture carcass in the extended state; Fig. 5 the order according to Fig. 4 with the front pull-out inserted into the furniture carcass; and Fig. 6 An exemplary embodiment of a piece of furniture with a built-in front extension in the extended position.

[0022] The in the Fig. The embodiments shown in Figures 1-6 exhibit features which, in any combination or individually, may be relevant for the realization of embodiments of the invention.

[0023] The in the Fig. The frontal pull-outs 1 shown in Figures 1-6 are each suitable for installation in a piece of furniture, for example, a kitchen cabinet, in particular a base cabinet for a kitchen worktop. The frontal pull-out 1 has mounting plates 14 on opposite sides, by means of which the frontal pull-out 1 can be attached, in particular screwed, to opposite inner sides of outer walls 7 of a furniture carcass 8.

[0024] The front extension 1 has a drawer frame 2, which is attached to the outer walls 7 of a furniture body 8 via linear guides, in this case by means of the mounting plates 14. The linear guides 6 are part of a support frame 3 of the drawer frame 2, which has a receptacle 4 for a waste bin 5 of a waste separation system.

[0025] The support frame 3 divides the drawer frame 2 in the width direction between the opposing linear guides 6 into a section in which the mounting 4 is arranged and a section which is open via a recess 9 in the depth direction of the front extension 1, i.e., in the adjustment direction of the linear guides 6. This creates space in the drawer frame 2 for the installation of a kitchen appliance, for example, a water purifier.

[0026] The kitchen appliance (not shown) can be arranged standing or wall-mounted in the furniture unit 8, and in a position where the front pull-out 1 is inserted into the furniture unit 8, it is received in the recess 9. In a position where the front pull-out 1 is fully or at least partially extended from the furniture unit 8, the recess 9 can be at least partially or fully positioned in front of the kitchen appliance.

[0027] The linear guide 6, which defines the recess 9, can be positioned in an upper area of ​​the front pull-out 1, creating a free space below the linear guide 6 for the kitchen appliance in the retracted position of the front pull-out 1. In the installed position, the kitchen appliance can thus be located entirely below the linear guide 6. Alternatively, in the mounting position of the kitchen appliance, the linear guide 6 can be positioned between the kitchen appliance and the outer wall 7 or the mounting plate 14.

[0028] Opposite the linear guide 6, which defines the recess 9, a strut 12 extending parallel to the linear guide 6 is arranged, which defines the recess 9 on one side and the receptacle 4 for the waste bins 5 on the other. A stiffening element 13 is formed on the strut 12. The stiffening element is essentially a plate. The stiffening element extends essentially perpendicular to the plane spanned by the support frame 3 and parallel to the adjustment direction of the linear guides 6. The stiffening element 13 has fastening means on one side connected to the end rail 10, in this case a retaining bracket, by means of which the stiffening element 13 can be supported and attached to the furniture front 11.

[0029] Because the linear guides 6 have the maximum possible distance between them, by being designed to be mounted on each of the two opposite outer walls 7 of a furniture carcass 8, directly or indirectly via the mounting plates 14, the front extension 1 has a high degree of stability and, accordingly, a low tendency to jam when it is manually operated via the furniture front 11 to be moved between the retracted position and the extended position. Although the support frame 3 for receiving the waste bins 5 only occupies part of the distance between the linear guides 6, the front extension 1 has a high degree of stability and, accordingly, a low tendency to jam when it is manually operated via the furniture front 11 to be moved between the retracted position and the extended position.

[0030] Fig. Figure 1 shows a perspective view of a front pull-out unit 1, specifically designed for installation in a piece of furniture, such as a sink base cabinet. The front pull-out unit 1 comprises a drawer frame 2, which is equipped with a support frame 3. The support frame 3 is designed to include at least one recess 4 for a waste bin 5. This design allows for efficient use of the available space within the furniture unit.

[0031] The drawer frame 2 is equipped with two parallel and spaced-apart linear guides 6. These linear guides 6 are designed to be mounted on opposite outer walls of a furniture carcass. The linear guides 6 ensure stable and smooth movement of the drawer frame 2 between an extended and a retracted position.

[0032] A special feature of the front pull-out 1 is the recess 9, which is located in a portion of the space between the linear guides 6. This recess 9 is open on one side in the direction of travel of the linear guides 6 and provides space for a kitchen appliance, preferably a water purifier. The recess 9 is designed so that, in the extended position of the front pull-out 1, it is positioned in front of the kitchen appliance, and in the retracted position, it fully or partially accommodates the kitchen appliance.

[0033] The support frame 3 is equipped with an end-face rail 10, which in this case is designed for mounting and / or supporting a vertical furniture front. The end-face rail 10 extends between the opposing linear guides 6 and is designed to form a stable connection between the linear guides 6 and the support frame 3. This arrangement provides the drawer unit 2 with additional stability and prevents it from jamming during movement.

[0034] Additionally, a strut 12 is provided, which limits the recess 9 and extends parallel to the linear guides 6. A stiffening element 13 is attached to this strut 12, which is designed for mounting and / or support on a vertical furniture front. The stiffening element 13 provides additional stability and supports the structural integrity of the front extension 1.

[0035] The design of the front pull-out 1 allows for efficient use of space while simultaneously offering the possibility of integrating a kitchen appliance into the cabinet body without compromising the pull-out's stability. The linear guides 6 are designed to maintain the maximum possible distance by being mounted on the opposite outer walls of the cabinet body. This contributes to the high stability of the front pull-out 1 and minimizes the tendency for it to jam when operated manually via the cabinet front.

[0036] Fig. Figure 2 shows a top view of an exemplary embodiment of a front extension 1. The front extension 1 comprises a drawer frame 2, which is equipped with a support frame 3.

[0038] Between the linear guides 6 is a recess 9, which is open in the adjustment direction of the linear guides 6. This recess 9 provides space for the installation of a kitchen appliance, for example a water purifier, without affecting the stability of the front extension 1.

[0039] The support frame 3 is equipped with an end-face rail 10, which serves for mounting and / or supporting a vertical furniture front. The end-face rail 10 extends between the opposing linear guides 6 and, together with them, forms a U-shape. The recess 9 is open on the open side of the U-shape.

[0040] A strut 12, extending parallel to one of the linear guides 6, defines the recess 9 and simultaneously serves to stabilize the drawer frame 2. The strut 12 is provided with a stiffening element 13, which is designed for mounting and / or support on a vertical furniture front.

[0041] The illustrated arrangement allows for ergonomic operation of the front extension 1 by preventing jamming during adjustment. This is achieved through the stable construction of the drawer frame 2 and the optimal arrangement of the linear guides 6.

[0043] The support frame 3 has an end-face rail 10, which serves for mounting and / or supporting a vertical furniture front (not shown). The end-face rail 10 extends between the opposing linear guides 6. The support frame 3 is designed such that it has a recess 9 which is open in the adjustment direction of the linear guides 6. This recess 9 allows the integration of a kitchen appliance, preferably a water treatment device, without destabilizing the front pull-out 1.

[0044] The linear guides 6 are arranged to have the maximum possible distance between them by being mounted on the opposite outer walls 7 of the furniture body. This ensures high stability of the front extension 1 and reduces the tendency for it to jam when being adjusted.

[0045] The support frame 3 divides the drawer frame 2 in the width direction between the linear guides 6 into a section with the receptacle 4 for the waste bin 5 and a section with the recess 9. The recess 9 provides space for a kitchen appliance. A strut 12 of the support frame 3 defines the recess 9 and extends parallel to the linear guides 6. The strut 12 is provided with a stiffening element 13, which is designed for mounting and / or support against a vertical furniture front.

[0046] The stiffening element 13 is essentially plate-shaped and extends perpendicular to the plane spanned by the support frame 3 and parallel to the adjustment direction of the linear guides 6. Fastening elements, such as a retaining bracket, are provided on one side of the stiffening element 13, which faces the end rail 10. These fasteners enable the stiffening element 13 to be supported and attached to the furniture front.

[0047] The illustrated embodiment of the frontal pull-out 1 shows how the various components of the system are connected and function to provide a stable and ergonomic solution for integrating a kitchen appliance into a furniture body.

[0048] Fig. Figure 4 shows a top view of a front pull-out 1 installed in a furniture carcass 8 in the extended position. The front pull-out 1 is designed for installation in a piece of furniture, in particular a sink base cabinet, and has a drawer frame 2. The drawer frame 2 is attached to the opposite outer walls 7 of the furniture carcass 8 by means of two parallel and spaced-apart linear guides 6.

[0049] The drawer unit 2 comprises a support frame 3, which has at least one receptacle 4 for a waste bin 5. In the illustrated embodiment, a waste bin 5 is arranged in the receptacle 4 of the support frame 3. The support frame 3 extends between the linear guides 6 and is designed to provide high stability and a low tendency to tilt.

[0050] Between the linear guides 6 is a recess 9, which is open in the adjustment direction of the linear guides 6. This recess 9 provides space for a kitchen appliance, preferably a water purifier. The recess 9 is arranged such that, in the extended position of the front pull-out 1, it is at least partially or completely in front of the kitchen appliance, while in the retracted position of the front pull-out 1, the kitchen appliance is received in the recess 9.

[0051] The support frame 3 has an end rail 10 that extends between the opposing linear guides 6 and serves to mount and / or support a vertical furniture front 11. The end rail 10 is directly connected to the linear guides 6 and together they form a U-shape. The end rail 10, the linear guides 6, and the support frame 3 are arranged in the same plane, which contributes to increased stability of the drawer frame 2.

[0052] A strut 12, extending parallel to one of the linear guides 6, defines the recess 9 and simultaneously serves to delineate the receptacle 4 for the waste bins 5. The strut 12 is provided with a stiffening element 13, which is designed for mounting and / or support on the vertical furniture front 11. The stiffening element 13 extends essentially perpendicular to the plane spanned by the support frame 3 and parallel to the adjustment direction of the linear guides 6.

[0053] By arranging the linear guides 6 on the opposite outer walls 7 of the furniture body 8, maximum stability of the front extension 1 is achieved. This enables ergonomic operation of the front extension 1 by preventing jamming when adjusting the front extension 1, especially when sliding it into the furniture body 8. The mounting plates 14 serve to securely mount the linear guides 6 to the outer walls 7 of the furniture body 8.

[0054] Fig. Figure 5 shows a top view of a front extension 1 installed in a furniture carcass 8 in the retracted position. The front extension 1 comprises a drawer frame 2, which is attached to the opposite outer walls 7 of the furniture carcass 8 via linear guides 6. The linear guides 6 enable smooth and stable movement of the drawer frame 2.

[0055] The drawer unit 2 has a support frame 3 which includes a receptacle 4 for a waste bin 5. The support frame 3 divides the drawer unit 2 in the width direction between the linear guides 6 into a section with the receptacle 4 and a section with a recess 9. This recess 9 extends in the depth direction of the front pull-out 1 and is open in the adjustment direction of the linear guides 6 to provide space for a kitchen appliance, such as a water purifier.

[0056] The end rail 10 of the support frame 3 extends between the linear guides 6 and serves to mount and support a vertical furniture front 11. The recess 9 is bounded by the end rail 10, one of the linear guides 6, and the support frame 3. The recess 9 is open on one side opposite the end rail 10.
