Description

Technical Field

[0001] The present invention relates to an assembly for assembling a body structure, particularly for an undercabinet (Unterschrank), a body structure including such an assembly, and a method for assembling a body structure.

[0002] In the following, the prior art will be described based on an undercabinet. Generally, the same also applies to the body structure.

[0003] From the prior art, it is known that an undercabinet is composed of a plurality of surface elements, and the surface elements form side walls, a bottom, a rear wall, a cover plate, and optionally intermediate elements.

[0004] In known embodiments of the prior art, these surface elements are connected to each other via fixing elements. These fixing elements are often screws threaded into the surface elements and are angles that connect them to each other.

[0005] Other embodiments of connection elements made within the surface elements are also well known.

[0006] However, in corresponding embodiments, in order to connect the individual surface elements, the fixing elements are always screwed into, incorporated into, and / or inserted into the surface elements themselves. Therefore, the surface elements must not only withstand environmental stress but also have sufficient rigidity to accommodate the fixing elements.

[0007] Furthermore, often these accommodated fixing elements screwed into the surface elements form weak points, and when the load is large, the cross-section of the surface element is weakened at the screwing or incorporation location of the fixing element, and often damage or breakage occurs at this location (if the robustness of the surface element is insufficient).

[0008] Another drawback is that during manufacturing and assembly, considerable energy and time must be spent to create corresponding accommodating holes and openings in the surface elements, and / or to measure and / or provide positions for accommodating the fixed elements.

[0009] Furthermore, each surface element needs to be prepared for later use and therefore must be allocated to the area of ​​later use, which results in increased logistical effort.

[0010] Therefore, in summary, in the case of under-cabinets, each surface element must be prepared in advance for subsequent assembly, handled individually for transportation to the area of ​​use, and at the site of use, each surface element must be individually positioned by experts according to its purpose and connected to each other via fixed elements.

[0011] Therefore, there is a need for a way to manufacture under-cabinets more easily, which would not only reduce manufacturing effort but also minimize logistical challenges and, in some cases, even reduce assembly work.

[0012] Therefore, the object of the present invention is to realize an assembly for assembling a main body structure, a main body structure, and a method for assembling a main body structure that can reduce manufacturing labor, and / or reduce or eliminate assembly work, and / or reduce logistics work for transportation, and / or improve environmental aspects by reducing transportation mass or the amount of material required.

[0013] This problem is solved according to the present invention by an assembly for assembling a main body structure having the features of claim 1, a main body structure formed from at least one such assembly having the features of claim 17, and a method for assembling a main body structure having the features of claim 20.

[0014] According to the present invention, the main body structure, in particular the assembly for assembling the under cabinet, is intended to have at least four vertical columns, each of which is intended to have a first fastening device for attaching at least one first surface element parallel to the vertical column without tools, and at least one second fastening device for attaching at least one second surface element laterally to the vertical column without tools.

[0015] By providing corresponding vertical supports that enable the assembly of surface elements without tools, it becomes possible to connect surface elements to each other via vertical supports and their fixing devices without separate holes or receiving openings.

[0016] Therefore, the cross-section is no longer weakened by holes and / or openings for fixing, allowing the surface elements to be designed to have a smaller cross-section.

[0017] Reducing the size of surface elements has the advantage of requiring less material for each element, which in turn reduces the mass that needs to be transported, leading to transportation advantages and ultimately significant improvements in terms of the environment and ecology.

[0018] On the other hand, it eliminates the need to design surface elements with openings and / or holes or other elements for fixing, thereby minimizing the manufacturing effort (cutting) required for the pre-fabrication of surface elements.

[0019] Furthermore, this is an improvement in that it eliminates the need to necessarily allocate surface elements to subsequent uses. Therefore, since the components can be manufactured identically, it is no longer necessary to allocate surface elements to, for example, the left or right side of the main structure, thereby reducing logistical effort for transportation, manufacturing, and assembly.

[0020] Furthermore, the vertical supports allow for tool-free assembly, thereby reducing assembly effort and complexity.

[0021] The vertical supports further reinforce the main structure, which allows for a further reduction in material usage and the dimensions of surface elements.

[0022] Furthermore, the vertical elements make it possible to achieve even highly sophisticated prefabrication.

[0023] For example, as will be explained in more detail later, the vertical elements can be equipped with elements such as electrical shafts, housing elements for mounting plates or pedestal legs, electrification, or fixing points for covers, and the assembly is greatly simplified because these do not need to be added during assembly.

[0024] Furthermore, by reducing the dimensions of the surface elements, storage space can be increased, and the internal space of the main structure can be expanded while maintaining the same external dimensions. In other words, available space can be used more efficiently to create storage space.

[0058] Figure 1 shows an exemplary embodiment of the main body structure 1 according to the present invention, in which the main body structure 1 is designed as an under-cabinet.

[0059] The main structure 1 comprises four vertical support columns 2 that essentially form the vertical sides of a rectangular prism.

[0060] The vertical support column 2 connects to the first surface element 5, thereby realizing the main body structure 1.

[0061] The top panel 28 is placed on top of the main body structure 1.

[0062] With respect to the floor, the main structure 1 is supported by stand legs 29 positioned at the lower end of the vertical support column 2.

[0063] Six drawers 10 are arranged within the internal space of the main body structure via drawer guides 9 positioned on vertical support columns, and these can be pulled out from the main body structure 1 by the drawer guides 9.

[0064] Figure 2 shows an exploded view of the exemplary embodiment of Figure 1.

[0065] Figure 2 shows that the first surface element 5, which is positioned parallel to the vertical support 2, is connected to the vertical support 2 via the second fixing device 4.

[0066] The second surface element 6, which is positioned substantially laterally with respect to the vertical support 2, is supported by the vertical support 2 via the first fixing device 3.

[0067] Furthermore, in order to enhance the stability of the main structure 1, the two vertical support columns 2 are connected to each other via another second fixing device 4 to which the horizontal member 17 is connected.

[0068] Figure 3 shows the connection between the two vertical supports 2 and the first surface element 5 separately. The precise fixing of the first surface element 5 to the vertical supports 2 using the second fixing device 4 will be explained in more detail later.

[0069] Figure 3 shows that the vertical support column 2 is composed of two sub-pieces 22 and 23, and these two sub-pieces 22 and 23 can be connected to each other without tools.

[0070] These vertical supports 2 are further equipped with second fixing devices 4 at the first end 20 and the second end 21 located on the opposite side, and the two second fixing devices 4 are designed in different structural forms.

[0071] Furthermore, the second fixing devices 4 located at ends 20 and 21 can be connected to the vertical support 2 via a push-in connection without tools, as will be shown in more detail in the following figure.

[0072] The second fixing device 4, located at the second end 21, is further connected to the stand leg 29.

[0073] Figure 4 shows an exploded view of the vertical support 2, from which it can be seen in more detail that the vertical support 2 is formed by two sub-pieces 22 and 23, which are connected to each other along the longitudinal axis of the vertical support 2 by the interlocking system 32.

[0074] By designing the vertical support column 2 accordingly from multiple sub-pieces 22 and 23, a system can be realized that allows for the lightweight and modular expansion of the vertical support column 2 and therefore the main structure 1. The vertical support column 2 can be made longer or shorter by adding or removing sub-pieces 22 and 23 according to the required length.

[0075] The insert system 32, shown in detail in Figure 4, is designed such that a protruding pin of the lower piece 22 engages with a corresponding recess of the upper piece 23, thereby positioning and aligning along the longitudinal extension of the vertical support 2.

[0076] The interlocking system 32 can be designed so that the individual pieces 22 and 23 can be connected to each other by insertion and held in place by the interlocking system 32, with appropriate dimensional tolerances (e.g., press fit).

[0077] Alternatively, within the area of ​​the plug-in system 32, the first piece 22 and the second piece 23 may be connected to each other via connecting bolts or screw connections.

[0078] A suitable clamp connection is also a viable option.

[0079] However, it is also conceivable that the relative positions of the parts 22 and 23 can be fixed by simply inserting the first part 22 into the second part 23, and then connecting the vertical support 2 to the first surface element 5 using the first fixing device 3 (this type of connection will be explained in more detail in the following series of diagrams).

[0080] The second fixing device 4, located at the lower end of the piece 22, is also held to the piece 22 by a corresponding insertion system 32.

[0081] The second fixing device 4 (shown in more detail in Figure 5) includes a base 30.

[0082] Figure 5 shows the second fixing device 4 in detail in an exploded view.

[0083] Stand legs 29 are further attached to this base 30.

[0084] More precisely, the stand legs 29 are designed to be attached to the base 30 so that they can be moved to adjust their height variably relative to the base 30 via the adjustment element 33.

[0085] The height of the stand legs 29 can be adjusted, for example, via an adjustment element 33, which can be rotated using, for example, a screwdriver. In this case, the gear rack system can also be used to change the relative position of the stand legs 29 with respect to the base 30.

[0086] The second fixing device 4 is also attached to the base 30.

[0087] The fixing device 4 includes an engaging element 16, which is biased against the second surface element 6 by a spring element 15, so that as soon as the second surface element 6 is positioned on the second fixing device 4, the engaging element 16, more precisely the hook of the engaging element 16, is pressed against the second surface element 6 via the spring element 15 and connected in a shape-coupled manner, thereby fixing (verankern) this hook of the engaging element 16 to the second surface element 6.

[0088] To allow the shape-bonded connection between the engaging element 16 and the second surface element 6 to be released again, the engaging element 16 can be disengaged via the actuating element 31. In this case, the actuating element 31, which is formed as a lever, rotates on the base 30 around the rotating bearing portion 34, thereby applying tension to the spring element 15, which causes the engaging element 16 to disengage from or retract from the second surface element 6.

[0089] Figure 6 shows the assembly of the main body structure 1, which consists of a vertical support column 2 and a first surface element 5. The connection between the first surface element 5 and the vertical support column 2 is achieved via a first fixing device 3.

[0090] These first fixing devices 3 can be seen in more detail in Figures 7 and 8, where Figure 7 shows the state of the vertical support 2 before the first surface element 5 is inserted, and Figure 8 shows the state of the vertical support 2 after it has been connected to the first surface element 5 via the first fixing devices 3.

[0091] In Figures 7 and 8, it can be seen that each vertical support 2 has two first fixing devices 3, thereby allowing the vertical support 2 to be connected to two first surface elements 5, or allowing these two first surface elements 5 to be connected to each other.

[0092] Each of the first fixing devices 3 has a groove 11 that extends along the longitudinal direction of the vertical support column 2, and each of the first surface elements 5 can be positioned parallel to the vertical support column 2 in the groove 11.

[0093] The groove 11 of the vertical support column 2 is further positioned to hold the retaining element 12 of the first fixing device 3.

[0094] These retaining elements 12 are geometrically connected to the first surface element 5 by inverted hook geometry 13 in order to hold the first surface element 5 in the groove 11 (as will be explained in detail in the following figure).

[0095] In this exemplary embodiment, the retaining element 12 elastically deforms so that when the first surface element 5 is inserted, the surface element 5 can be positioned in the groove 11. This elastic deformation of the retaining element 12 causes the inverted hook geometry 13 to be pressed against the first surface element 5, thereby positioning and / or holding the surface element 5 against the vertical support 2 in the groove 11.

[0096] Figure 9 shows the precise design and positioning of the retaining element 12, which has an inverted hook geometry relative to the vertical support 2, within the groove 11 of the vertical support 2.

[0097] Figure 10 shows the connection between the vertical support 2 and the second surface element 6.

[0098] In Figure 10, it can be seen that the vertical support 2 is first connected to the first surface element 5 via the first fixing device 3, and then this basic structure is connected to the second surface element 6 via the vertical support 2.

[0099] For this purpose, as indicated by the arrows, the two outer, unsupported (freistehend) vertical supports 2 and the first face element 5 connected to them are initially separated, which is made possible by the still-existing, somewhat fragile basic structure.

[0100] This separation allows the second surface element 6 to be inserted from the front, which in turn allows the second surface element 6 to be positioned on the four vertical support columns 2 and the second fixing device 4 connected thereto.

[0101] By bringing the second surface element 6 into contact with the second fixing device 4 (as is known from the preceding figures), the second surface element 6 is connected to the vertical support 2 by the engagement of the engaging element 16 with the second surface element 6.

[0102] By bringing the vertical support 2 or the second fixing device 4 into contact with the second surface element 6, the previously somewhat fragile structure is stabilized, thereby achieving a stable main body structure 1.

[0103] Figures 11 and 12 show two different exemplary embodiments of detail figure B shown in Figure 10, in which the front end of the second surface element 6 can be covered by a cover element (see Figure 11) or left uncovered and exposed forward (see Figure 12).

[0104] Figure 13 shows the alternative measures for Figure 10.

[0105] This figure shows one embodiment in which the first surface element 5 is first connected to the vertical support 2, and immediately after this step, the second surface element 6 is connected to the first surface element 5 via the second fixing device 4 of the vertical support 2.

[0106] Figure 14 shows various details of the main body structure 1.

[0107] It can be seen that a second fixing device 4 for connecting to the horizontal member 17 is further connected to the positioning element 14.

[0108] These positioning elements 14 are designed to position the first surface element 5 by pushing it downwards by the positioning element 14, which is designed as a leaf spring element, thereby connecting the first surface element 5 to the second surface element 6, or more precisely, pressing it against and / or biasing it against the second surface element 6.

[0109] One or more positioning elements 14 may be formed by plastic springs integrally injection-molded with the second fixing device 4.

[0110] Furthermore, at least two of the four vertical support columns 2 each have at least one furniture fitting, more precisely, at least one first interface 7 for securing the drawer guide 9, and the other two of the four vertical support columns 2 each have at least one second interface 8 for securing the furniture fitting, i.e., the drawer guide 9, and the first interface 7 and the second interface 8 are of different designs, and more precisely, it can be seen that the first interface 7 and the second interface 8 are positioned substantially rotated 90° relative to each other.

[0111] Detailed diagram C, shown in Figure 14, is shown in Figures 15 to 17, revealing a more detailed embodiment of the second fixing device 4 for fixing the horizontal member 17.

[0112] In that case, Figure 15 shows the second fixing device 4 combined with the horizontal member 17.

[0113] Figure 17 shows a cross-sectional view of Figure 15, and Figure 16 shows Figure C without the transverse member 17.

[0114] It can be seen that the second fixing device 4 for fixing the horizontal member 17 without tools has a clamping device 18.

[0115] This clamping device 18 has an eccentrically mounted lever 19, and the holding structure 36 can be moved by the pivoting motion of the eccentrically mounted lever 19.

[0116] This movement of the retaining structure 36 allows the retaining structure 36 having the raised portion to move closer to or further away from the surface of the transverse member 17, thereby allowing the retaining structure 36 to apply a clamping force to the transverse member 17 with the corresponding surface located on the opposite side of the fixing device, thereby fixing the transverse member 17 in position relative to the second fixing device 4.

[0117] The surface corresponding to the holding device 36 can also be designed to have a holding structure with raised and recessed portions.

[0118] Figure 18 shows a detailed view B of Figure 14, where the known stand legs 29 are again visible, but unlike the preceding figures, the exemplary embodiment of Figure 18 has a seal lip 35 positioned on the end face of the vertical support 2.

[0119] This sealing lip 35 can be designed to seal the drawer 10 that comes into contact with the main body structure 1 afterwards.

[0120] In this exemplary embodiment, the seal lip 35 can be attached to the vertical support 2, for example, by adhesive bonding, or the vertical support 2 may be intended to have a corresponding groove into which the seal lip 35 is inserted.

[0121] Figure 19 shows the connection between the vertical support column 2 and the pull-out guide 9.

[0122] To accommodate the drawer guide 9, the vertical support column 2 has interfaces 7 and 8, as can also be seen in Figure 14.

[0123] The pull-out guide 9 (see the detailed diagram in Figure 20) is designed to be equipped with a connecting element 27 for corresponding connection to interfaces 7 and 8.

[0124] As shown by the arrows in Figure 19, in the first step, the pull-out guide 9 is introduced into the second interface 8 by the rear connecting element 37 and moved forward, thereby fixing the connecting element 37 to the second interface 8.

[0125] In the next step, the forward connecting element 37 is introduced into the first interface 7 and fixed downward, thereby precisely positioning the drawer guide 9 relative to the vertical support 2 and thus the main body structure 1.

[0126] Furthermore, the drawer guide 9 has a safety element 38 that is realized by a partially elastic structure.

[0127] This partially elastic structure of the safety element 38 engages with the upper geometry of the first interface 7 (see Figure 14 for this) after the forward connecting element 37 has locked onto the first interface 7, thereby securing the pull-out guide 9, or more precisely, the forward connecting element 37, to the first interface 7 so that upward movement is prevented except when the safety element 38 is intentionally pulled out from the first interface 7 again.

[0128] Therefore, the safety element 38 ensures that even if force is generated in the drawer 10 during use and operation of the main body structure 1, the drawer guide 9 will not change its position on the vertical support column 2, thereby guaranteeing frictionless operation of the drawer guide 9.

[0129] Furthermore, the drawer guide 9 is provided with a fixed opening 40.

[0130] These fixed openings 40 can also be used, either alternatively or additionally, to connect the drawer guide 9 to the vertical support 2 by fastening means (e.g., screw fittings (Verschraubung)).

[0131] Figure 21 shows another exemplary embodiment of the main body structure 1, which, strictly speaking, shows the different positioning possibilities of the adjustment element 33 for height adjustment of the stand leg 29, as shown in the exemplary embodiment of the illustrated detail drawings.

[0132] For the principle of height adjustment of the stand legs 29, please refer to the preceding diagram.

[0133] Figures 22 and 23 show cross-sections of the vertical support column 2, and in these cross-sections, it can be seen that, for example, according to the exemplary embodiment in Figure 22, the vertical support column 2 can be designed as an aluminum extruded casting part or an extruded plastic part.

[0134] However, according to the exemplary embodiment shown in Figure 23, it is also quite conceivable that the vertical support column 2 be designed as a component made of sheet metal, preferably thin metal sheet material.

[0135] However, as can be seen from the modified forms in both Figures 22 and 23, the vertical support 2 has a connection interface 24 in addition to the known components.

[0136] The connection interface 24 is designed to connect the vertical support 2 to the outer cover element 25 (see Figures 26 and 27 for this), and / or to directly connect the vertical support 2 to the vertical support 2 of another main structure 27 (see Figures 24 and 25 for this).

[0137] For example, Figures 24 and 25 show how the vertical support column 2 of the main body structure 1 can be connected to another vertical support column 2 of another main body structure 27 using the connection interface 24.

[0138] In this case, both vertical posts 2 have connecting grooves 26. Subsequently, connecting elements 39 are introduced into these connecting grooves 26, and these connecting elements 39 connect the two vertical posts 2 to each other.

[0139] Figures 26 and 27 show exemplary embodiments of connection interfaces 24 for connecting vertical supports to cover plates 25.

[0140] Such a cover plate 25 can be placed on the main body structure 1 to refine or shape its appearance.

[0141] For this purpose, a connection interface 24 is formed on the vertical support column 2 by a connection groove 26.

[0142] The connecting element 39 can be positioned on the cover element 25 by means of adhesive bonding or screw connection, and in this case as well, the connecting element 39 and the position of the connecting element 39 in the connecting groove 26 of the vertical support 2 can connect to the cover element 25.
