Description

Technical Field

[0001] The present invention relates to a frame system for installation in work furniture.

[0002] The invention also relates to a piece of work furniture having a frame system. Background Art

[0003] Although generally applicable to any work furniture, the invention is explained in relation to sanitary furniture in the form of kitchen base cabinets.

[0004] Kitchen cabinets are often used to accommodate various appliances, such as waste separation systems for sink users and possibly water treatment appliances, etc. Since individual boundary conditions, such as the width, depth and height of the kitchen cabinets, usually have to be taken into account, which can also be changed by the user at short notice, it is known to fasten the individual appliances directly to the cabinets or to their movable fronts, such as doors. The individual appliances have different sizes and are fastened directly to the cabinets at the appropriate locations by the installer on site, which requires a great deal of assembly work in terms of time and complexity.

[0005] In order to at least partially separate the pipes of the sink from other equipment to be arranged, it is known from DE10317071A1 to provide a rectangular mounting frame in the base cabinet, which is fixed in the base cabinet and includes: frame pillars formed by mutually connected and basically rectangular frames, auxiliary pillars fastened to the frames and located in the frame plane, and angle valves fastened to the auxiliary pillars, the angle valves having pressure-resistant connecting hoses for countertop outlet accessories for connecting to the wall-side water inlet pipes, wherein the complete mounting auxiliary frame can be used in the chamber of the base cabinet, the chamber of the base cabinet is basically open to the wall behind it, and can also be fastened to the bottom and / or side walls of the base cabinet, and the mounting frame also includes a cover covering the mounting frame on the front side, and the cover can be detachably fastened to the mounting frame.

[0006] Disadvantages here are the complex construction and the lack of flexibility when installing larger and / or heavier components.

[0007] In order to solve this problem, a two-part frame module is known from DE 10 2021 203 803 A1, which can be divided into functional components by separating elements within the frame module.

[0008] However, the disadvantage here is that although the frame modules can be preassembled with functional components such as drawers, water treatment units, etc., it is obviously much more difficult for the user's fitters to bear the frame modules with preassembled functional components on site due to the heavy weight of the connection. Another disadvantage is that it is not possible to arrange the functional components differently according to the customer's wishes, such as drawers on the left and water treatment units on the right, without complicated separation and reassembly. Likewise, the width of the frame modules cannot be changed, which makes it impossible to adapt them to base cabinets of different sizes. Summary of the invention

[0009] Therefore, the object of the present invention is to provide a frame system and a piece of work furniture having a frame system, which can be more flexibly adapted to base cabinets of different sizes and can improve the operability at the customer's site.

[0010] Another object of the present invention is to provide an alternative frame system and an alternative work furniture having a frame system.

[0011] In one embodiment, the present invention achieves the above-mentioned purpose by a frame system for installation into work furniture, in particular sanitary furniture work pieces, the frame system comprising a first frame module and a second frame module, wherein the first frame module and the second frame module respectively have at least one insertion opening for inserting at least one pre-installed functional component for the user, wherein the corresponding insertion opening has a quadrilateral cross-section, and the first frame module and the second frame module can be fixed to each other by means of a tool-free connection.

[0012] In one embodiment, the invention is achieved by a piece of work furniture having a frame system according to any one of claims 1 to 18 .

[0013] The term "sanitary" is to be understood in the broadest sense and, in particular in the description, preferably in the claims, refers in particular to any object, arrangement, device, installation or the like relating to a bathroom, a kitchen, a heating system or the like.

[0014] The expression "installed in a piece of work furniture" is to be understood in the broadest sense and refers in particular in the claims and preferably in the description to any arrangement in, on, between or under one or more pieces of work furniture. In particular, the expression refers not only to the installation of the frame system in a piece of work furniture, but also to an arrangement on the floor below a work board and between two separate pieces of work furniture.

[0015] The phrase "tool-free connection" is to be understood in the broadest sense and refers in particular in the claims and preferably in the description to any form-fitting, material-locking and / or force-locking connection which is achieved and can also be achieved again manually and / or without the use of an object defined in the sense of a tool. A tool-free connection can be, for example, a snap-in connection, in which the tab engages in the corresponding opening when a corresponding component with a tab is manually inserted into a component with an opening. The snap-in connection can then be released again manually or with an object, such as a pencil, by pressing in or lifting the tab. A pencil does not represent a tool in the sense of the invention.

[0016] One of the advantages is that it is easier for the installer to bear, in particular if the functional components are already pre-assembled. Thus, the functional components can be pre-assembled in each of the two frame modules, and the two frame modules can be more easily beared, since they themselves have a lower weight and are only fastened to one another, for example, in a kitchen base cabinet or the like. The frame modules can also be adapted more flexibly to base cabinets of different sizes. For example, one of the frame modules can always have the same dimensions, while the other of the two frame modules can have different dimensions, so that different sizes of base cabinets can be taken into account when arranging the two frame modules. Since the first frame module always has the same dimensions, it can be manufactured cost-effectively, which reduces the costs of the frame system overall.

[0017] Further features, advantages and further embodiments of the invention are described below or are obvious from the invention.

[0018] According to an advantageous development of the invention, the third frame module can be fixed to each side of the first frame module and the second frame module, wherein the sides of the first frame module and the second frame module form a common plane.

[0025] According to another advantageous improvement of the present invention, at least one shielding strip can be arranged on at least one frame module, which has the advantage of improving the adaptability to different work furniture and having a higher visual appeal.

[0026] According to another advantageous development of the invention, at least one blind strip can be connected to at least one frame module in a releasable or non-releasable manner, in particular by means of an adhesive connection. A releasable connection has the advantage that the frame system can be separated if necessary for maintenance. An non-releasable connection has the advantage that a particularly simple and cost-effective connection is provided.

[0027] According to another advantageous development of the invention, one or more fixing elements are arranged for fixing the frame modules to each other and / or for fixing at least one shielding strip to at least one frame module. This has the advantage that the reliability of fixing the frame modules to each other can be improved.

[0028] According to a further advantageous improvement of the present invention, the third frame module has a U-shaped cross section, including a bottom and two sides, wherein the third frame module can be fixed to the first frame module and the second frame module by its bottom. This has the advantage that functional components can be easily arranged in the third frame module.

[0029] According to another advantageous development of the present invention, the third frame module has, in particular, rectangular recesses on two sides. This has the advantage that, on the one hand, the handling of the third frame module is simplified, and on the other hand, the functional components can be easily fixed in the recesses.

[0030] According to another advantageous development of the invention, at least one drawer element and / or waste separation element and / or water treatment unit can be arranged in one or more frame modules. This has the advantage that the frame module device with functional components can be flexibly adjusted to adapt to different customer specifications.

[0031] According to a further advantageous development of the invention, the base module can be connected to the first frame module and the second frame module by a detachable connection, in particular a threaded and / or snap-on connection, and / or an inseparable connection, in particular an adhesive connection. This has the advantage of being easy to assemble and detach during maintenance.

[0032] According to a further advantageous development of the invention, the third frame module has an edge, in particular a fold, oriented perpendicularly to the common plane, in particular the edge is arranged opposite the fold of the first and / or second frame module in the region in which the third frame module rests on the first and second frame modules. This has the advantage that functional components can be arranged reliably in the third frame module.

[0033] According to a further advantageous development of the invention, the plug connection can be provided in the form of a U-shaped fold on one of the two frame modules (the first frame module and the second frame module), which fold can be pushed onto the edge of the other of the two frame modules. This has the advantage of simple assembly and at the same time securely fixing the frame modules to each other.

[0034] According to a further advantageous development of the invention, the third frame module has a U-shaped fold which can be pushed onto the edge of the first and / or second frame module. This has the advantage of simple assembly and reliable fixing of the third frame module to the first and second frame modules.

[0035] According to a further advantageous improvement of the present invention, the compensation module and / or the storage module can be fixed to the work furniture and / or the frame system.

[0045] Figure 1 A frame system according to an embodiment of the present invention is shown.

[0046] Figure 1A frame system 100 is shown, which comprises two frame modules 1, 2 with a rectangular cross section. The frame modules 1, 2 each have an insertion opening 1a, 2a. On the side of the frame modules 1, 2 facing away from the insertion opening 1a, 2a, there is also an opening, which is of the same size here and is not provided with a reference numeral. The two frame modules 1, 2 can be fixed to each other by means of a tool-free connection, here a plug connection 7. The first frame module 1 can be fixed with its left side face 1d to the right side face 2d of the second frame module 2. On the upper sides 1b, 2b of the two frame modules 1, 2 forming a common plane 5, a third frame module 3 is arranged, which has a U-shaped cross section and has a bottom 3a placed on the upper sides 1b, 2b of the frame modules 1, 2 and is detachably connected to the frame modules 1, 2, and has two edges 3b, 3c protruding vertically upward from the plane 5. The edges 3b, 3c each have a side recess 12a, 12b of rectangular design. The third frame module 3 is designed such that it extends along direction 6 over the entire width of the two frame modules 1 , 2 . The depth of the third frame module 3 is smaller than the depth of the two frame modules 1 , 2 .

[0047] Figure 2 A work piece of furniture according to an embodiment of the present invention is shown.

[0048] exist Figure 2 , a work furniture 200 which is basically designed in a box shape is shown. In the lower area of ​​the work furniture 200, the first frame module 1 is arranged on its right side and the second frame module 2 is arranged on its left side. The two frame modules 1 and 2 are arranged at the bottom of the work furniture 200 and fixed to the bottom if necessary. Likewise, the two frame modules 1 and 2 can be fixed to each other without tools. A water treatment unit 15 is arranged in the first frame module 1, a pull-out trash can 14 is arranged in the lower area of ​​the second frame module 2, and a drawer element 13a is arranged above it. A third frame module 3 is arranged above the two frame modules 1 and 2, and the third frame module has another drawer element 13b extending over the entire width of the work furniture 200.

[0049] Due to the height of the work furniture 200, a stop 21 is now arranged on the work furniture 200 above the third frame module 3, which is detachably fastened to the other two frame modules 1, 2. Above the stop 21, a storage tray 20 is again arranged directly on the work furniture 200, which is located below the crossbar 22 of the work furniture 200. In this way, the gaps between the modules can be covered or concealed, so that a high-quality overall visual impression is maintained.

[0050] Figure 3 A frame system according to an embodiment of the present invention is shown.

[0051] Figure 3Mainly show that according to Figure 1 The frame system 100. Figure 1 The frame system 100 is compared to the Figure 3 In the frame system 100 of FIG. 1 , the fourth frame module 4 is now shown in the form of a base module. Here, the two frame modules 1, 2 are detachably connected to the upper side of the base module 4 with their respective lower sides 1c, 2c forming a common plane 5a, in particular by screws 11c, 11d, 11e. The two frame modules 1, 2 are detachably fixed to each other by additional fixing elements (here in the form of screws 11a, 11b). In addition, on the right side 2d and the left side 1d of the first and second frame modules 1, 2 and on the outer surface of the third frame module 3 corresponding to the side surfaces 1d, 2d, L-shaped shielding strips 10a, 10b are arranged by means of adhesive connection. This is used to compensate or cover the gap between the frame modules 1, 2 and the work furniture 200. The base module 4 also has height-adjustable feet 8 and depth-adjustable spacers 9 in the rear area.

[0052] The modular structure of the frame system 100 shown in the figure includes an embodiment of a frame system, which has a base module 4, a first and a second frame module 1, 2 as a common bottom module, a panel module 21, a drawer module 3 as a third frame module and an organization module 20. The modules 4, 1, 2, 3, 21, 20 are stacked and connected in the vertical direction. During assembly, for example in a kitchen base cabinet, the base module 4 is not required. The panel module 21 and the drawer module 3 are designed so that they can be arranged accordingly according to planning requirements or the drawer module 3 is at least partially installed under the panel module 21. The organization module 20 forms a closure on the upper side. The height of the panel module 21 and the drawer module 3 can be designed so that by combining two modules 3, 21 or by omitting one of the modules 3, 21, combined with the movement path of the organization module 20 in the vertical direction, the maximum possible coordination in terms of the change of the main height of the base cabinet of the work furniture 200 is achieved. The modular arrangement in the horizontal direction shown here is designed for a 60 cm wide kitchen base cabinet and can be adapted to narrower and wider kitchen base cabinets within the meaning of the present invention in terms of the horizontal range.

[0053] Depending on the cabinet width, the bottom module is divided into at least two submodules (a first frame module 1 and a second frame module 2). This division can be performed at least in the vertical direction. The bottom modules 1, 2 or the modules 3, 20, 21 above them can be designed to be symmetrical or asymmetrical in the horizontal direction. The frame modules 1, 2 are designed so that they can represent the right and left variants of the frame modules 1, 2, respectively. To this end, the individual modules 1, 2 are rotated 180 degrees around the vertical axis and then connected to each other. The connection of the modules 1, 2, which can be designed to be separable or inseparable, can be performed during production or can only be performed during assembly at the customer's site using special metal plate connections. Threaded connections, press-fit elements, etc. can be used as connecting elements for the modules.

[0054] For example, one of the two frame modules 1, 2 can include a water treatment unit 15. Here, the water treatment unit 15 can be directly installed into the respective frame module 1, 2, rather than just pushed into the frame module 1, 2. Therefore, the housing of the respective frame module 1, 2 also represents the housing of the water treatment unit 15. The water treatment unit 15 can be mounted on a carrier unit (not shown) and then inserted into the respective frame module 1, 2 during assembly. Cables and connecting lines are guided through or connected to the rear side baffle and / or the front side baffle of the water treatment module 15.

[0055] The modules placed on the two frame modules 1, 2 can have a smaller depth to avoid collisions with sinks or drain pipes. In one embodiment, the baffle module 21 is designed so that it contributes to the reinforcement of the entire frame system 100 in terms of deflection and / or torsion by geometry and / or cross section. The baffle module 21 can extend over the entire width defined by the plane 5 of the insertion openings 1a, 2a of the frame system 100. In addition, the baffle module can be designed to have a rectangular frame with inserted baffles in the front view. The advantage is that the baffle module 21 can be approached. This opening option in turn makes it possible to arrange technical equipment or functional elements in the baffle module 21. For example, this can include a hose guide / hose reel for equipping a pull-out shower or a water distribution module.

[0056] For example, for an embodiment with a base module 4, no kitchen base cabinets are needed. The base module 4 can be provided as a separate component together with the frame system 100. A variation of the assembly sequence is that the base module 4 is first arranged between the existing kitchen base cabinets and aligned using the leveling screws 11c, 11d, 11e. In one embodiment, the spacing to the wall or adjacent cabinets can be achieved by means of screw-like elements 9. In another embodiment, the spacing can also be achieved using sheet metal elements molded onto the base module.

[0057] In order to provide a visually appealing front view of the kitchen unit, shielding strips 10a, 10b can be arranged laterally on the frame system 100, which comprises at least the frame modules 1, 2 and at least the third frame element 3, and the frame system 100 is delivered fully assembled. These shielding strips 10a, 10b can be made of the same material as the adjacent body and can be cut directly on site from prefabricated assembly strips, for example.

[0058] In one embodiment, two strips of double-sided tape may be provided on each side to facilitate the positioning of the mounting strips. The side guards 10a, 10b are fixed by threaded connections through holes provided in the frame system 100. In one embodiment, the lateral mounting strips may be plugged in using a clamping connection, a plug and / or a snap-fit ​​connection.

[0059] It is also conceivable to use a front panel instead of the mounting strip. The front panel is not arranged on the side of the frame system 100, but is plugged onto the frame system 100 at the front using a plug connector.

[0060] In another embodiment, the aforementioned front panel can be arranged laterally on the frame system 100 using corner pieces. This has the advantage that functional parts of the frame element 100 are not covered by the front panel.

[0061] Figure 4 and Figure 5 In each case a cross section is shown in the region of a frame system according to an embodiment of the invention in which a third frame module rests on a first frame module.

[0062] exist Figure 4 , a cross section parallel to the side walls of the frame modules 1 , 2 is shown, more precisely the placement area 18 on which the third frame module 3 rests on the first and second frame modules 1 , 2. Figure 4 In the embodiment of the present invention, the frame module is denoted by the reference numeral 1, but this can also apply accordingly to the second frame module 2 as an alternative or in addition. The first frame module 1 has a fold that is bent inwards, i.e., in the direction of the insertion opening 1a of the frame module 1. The third frame module 3 has a fold 16a that extends mirror-symmetrically to the upper side 1b of the first frame element 1 and has an upright fold 17 in the area facing away from the insertion opening 1a.

[0063] exist Figure 5 In the embodiment, the first frame module 1 no longer has a fold. However, the third frame module 3 has a fold 16c that is bent downward in the direction of the insertion opening 1a, and the fold is designed so that it partially surrounds or encloses the straight edge 19 of the first frame module 1. In this way, the third frame module 3 can be fixed to the first frame module 1 by means of a plug connection. Accordingly, a connection between the first frame module 1 and the second frame module 2 can also be provided.

[0064] In summary, at least one embodiment of the present invention may provide at least one of the following advantages and / or the following features:

[0065] Flexible adaptation to different kitchen furniture.

[0066] Simple and cost-effective production.

[0067] Assembly of the frame modules is simple, fast and flexible.

[0068] Optimized module installation space.

[0069] The frame modules are securely fixed to each other.

[0070] The frame system is securely fixed in the work furniture.
