Description

Technology Field

[0001] The present invention relates to a double-wall drawer frame comprising an inner wall and an outer wall. Additionally, the present invention relates to a drawer having a double-wall drawer frame according to claim 15 and a method for mechanically and / or manually manufacturing a double-wall drawer frame according to claim 16. Background Technology

[0002] Double-wall drawer frames are already known from the latest technology. Double-wall drawer frames are generally manufactured by mechanical methods. The outer and inner walls of the double-wall drawer frame are positioned accordingly and connected to each other using appropriate connection techniques, for example, welded, glued, riveted, screwed, or clinched.

[0003] The disadvantage of the connection technologies mentioned above is that they are not suitable for the manual fabrication of double-wall drawer frames. In addition, in the case of mechanical fabrication methods, additional connection devices capable of implementing the connection technology, such as welding devices, bonding devices, riveting devices, screw connection devices, and / or clinching devices, are required.

[0004] Connecting the outer wall and the inner wall to each other can likewise be implemented by mechanical holding devices, such as those disclosed in WO 2013 / 090951 A1, for example. Thus, double-wall drawer frames can be installed manually and / or mechanically without additional devices.

[0005] A disadvantage of this latest technology is that mechanical holding devices typically have a certain amount of play, which can cause noise generation, particularly rattling, during the use of double-wall frames.

[0006] The objective of the present invention is to prevent noise generation during the use of double-wall drawer frames while keeping the fabrication of double-wall drawer frames simple.

[0007] According to the present invention, at least one spacer component may be positioned or arranged between an inner wall and an outer wall, and at least one spacer component may be clamped between at least one first protrusion and at least one second protrusion.

[0008] Since at least one spacer component is arranged or can be arranged between the inner wall and the outer wall, noise generation is prevented during the use of double-wall drawer frames.

[0009] Since at least one spacer component can be clamped between at least one first protrusion and at least one second protrusion, the fabrication of the double-wall drawer is performed particularly simply. In particular, at least one spacer component does not need to be clamped between the inner wall and the outer wall, and thus does not need to be held by the inner wall and / or the outer wall. Additionally, according to the present invention, at least one spacer component is provided to be shaped substantially in a plate-like form. Thus, at least one spacer component can be placed in close contact with the inner wall and / or the outer wall over a relatively large surface area and prevent noise generation.

[0010] In one exemplary embodiment of the present invention, it is provided that an outer wall or an inner wall may be connected to or is connected to an inner wall or an outer wall through at least one first protrusion and / or at least one second protrusion.

[0011] Therefore, at least one first protrusion and / or at least one second protrusion can be used for connecting between two walls and for clamping at least one spacer part, thereby making the structure particularly simple.

[0012] It may be provided that at least one first protrusion and / or at least one second protrusion protrudes laterally from the inner wall and / or outer wall. Thus, at least one spacer part can be held in the direction of the plane of the inner wall and / or outer wall.

[0013] In additional exemplary embodiments, at least one first protrusion and at least one second protrusion are rigidly, particularly integrally, connected to an inner wall and / or an outer wall. In particular, at least one first protrusion and / or at least one second protrusion are made of the same sheet metal as the inner wall and / or the outer wall. At least one first protrusion and at least one second protrusion are particularly preferably integrally connected to an inner wall. Thus, the number of components is reduced.

[0014] It may be provided that at least one first protrusion and / or at least one second protrusion extends over the entire length and / or entire width of the inner wall and / or outer wall.

[0015] In a particularly preferred exemplary embodiment, at least one first protrusion and / or at least one second protrusion forms the end faces of the double-wall drawer frame. The inner wall and the outer wall may be connected to each other, particularly preferably, through the end faces. The end faces preferably extend across the entire width of the inner wall and / or the outer wall.

[0016] It may be provided that at least one first protrusion and at least one second protrusion are arranged on two mutually opposite sides of an inner wall and / or an outer wall, preferably on the longer sides. This applies particularly to cases where at least one first protrusion and / or at least one second protrusion forms the end face of a double-wall drawer frame.

[0017] In a preferred exemplary embodiment, at least one spacer component is made of foam, particularly polyethylene foam, at least partially, preferably entirely. The Alveo NA 36 / 100 type is particularly preferably used as the foam. Noise generation can be prevented particularly effectively through the use of foam.

[0018] At least one spacer component is preferably formed elastically, so that permanent deformation does not occur even with long-term use.

[0019] At least one spacer component has a predetermined breaking point, preferably a perforation, particularly preferably. At least one spacer component can preferably be split along the predetermined breaking point without a tool. Thus, one type of spacer component can be used for double-wall drawer frames of different sizes. For example, the entire unbroken spacer component can be used for larger drawer frames, and only a portion of the original spacer component can be used for smaller drawer frames.

[0020] delete

[0021] In an exemplary embodiment, at least one spacer component is placed flat in close contact with an inner wall and / or an outer wall while clamped, thereby preventing noise generation.

[0022] In particular, at least one spacer part covers at least 1 / 4 of the surface area of ​​the inner wall and / or outer wall.

[0023] In a particularly preferred exemplary embodiment, at least one spacer component is arranged at a predetermined distance from a virtual plane while in a clamped state, and the virtual plane spans points where the outer wall or the inner wall is placed in close contact for connection to the inner wall. The distance is preferably between 0.1 millimeters and 0.5 millimeters.

[0024] At least one spacer component may be placed in close contact with an inner wall, for example, and may be arranged at a predetermined distance from a virtual plane, the virtual plane spanning points where the outer wall is placed in close contact for connection to the inner wall. The points where the outer wall is placed in close contact for connection to the inner wall may be arranged on at least one first and / or at least one second protrusion, for example, where the outer wall and the inner wall are connected through protrusions.

[0025] It may be provided that the outer wall or inner wall, while connected to the inner wall or outer wall, is curved in the direction of the inner wall or outer wall, so that as a result the outer wall or inner wall is placed in close contact with at least one clamped spacer part. In particular, the outer wall or inner wall may be placed in close contact with at least one clamped spacer part despite the existence of a distance as described in the previous paragraph. Then the curvature bridges a length of, in particular, 0.1 millimeters to 0.5 millimeters.

[0026] In a preferred exemplary embodiment, at least one first protrusion and / or at least one second protrusion has at least one guide groove for guiding an outer wall or an inner wall, preferably wherein at least one guide groove is shaped as a substantially semicircular bend of the sheet metal part. In particular, the guide groove is arranged only on the first protrusion.

[0027] It may be provided that a guiding-in surface for guiding an outer wall or an inner wall transversely along the longitudinal direction of at least one guide groove is adjacent to at least one guide groove, and preferably, at least one spacer component is placed in close contact with the end edge of the guiding-in surface while clamped. To guide the outer wall or the inner wall, a portion of the outer wall or the inner wall may be positioned in close contact with the guiding-in surface and pushed into the guide groove on the guiding-in surface.

[0028] It may also be provided that the outer wall or inner wall has at least one guide ridge for guiding into at least one guide groove. Thus, a connection may be created between the outer wall or inner wall and the protrusion.

[0029] Preferably, the guide ridge is shaped as a substantially semicircular bend of the sheet metal part, and preferably, the radius of at least one bend of at least one guide groove is larger than the radius of at least one bend of at least one guide ridge.

[0030] Additionally or alternatively, preferably, at least one guide ridge may be made of the same sheet metal part as the outer wall or inner wall, preferably made of the end piece of the outer wall or inner wall.

[0031] A double-walled drawer frame may include at least one holding device for holding at least one guide groove in close contact with at least one guide ridge. The holding device may grip the guide ridge before or during insertion into the guide groove.

[0032] In a preferred exemplary embodiment, at least one second protrusion and / or at least one first protrusion has a stepped shape. In particular, this shaping is provided for at least one second protrusion.

[0033] Preferably, at least one spacer component may be arranged in close contact with a first step starting from an inner wall or an outer wall while in a clamped state, and particularly preferably, at least one spacer component may be placed in close contact with a curve of at least one first step.

[0034] Preferably, at least one outer wall or inner wall may be provided to be arranged on a last, preferably second, step starting from the inner wall or outer wall while connected to the inner wall or outer wall.

[0035] In an exemplary embodiment, at least one second protrusion and / or at least one first protrusion has at least one suspension ridge for suspending an outer wall or an inner wall. In particular, such configuration is provided for at least one second protrusion.

[0036] It may be provided that the outer wall or inner wall has at least one suspension groove for suspending the outer wall or inner wall on at least one suspension ridge, and preferably, at least one suspension groove is formed as a bent end piece of the outer wall or inner wall.

[0037] In particular, the guide ridge and the suspension groove may be arranged on the outer wall, and the first and second protrusions may be arranged on the inner wall (or vice versa). The outer wall may be connected to the inner wall through the guiding of the guide ridge into the guide groove of at least one first protrusion and the engagement of the suspension groove behind the suspension ridge.

[0038] A method according to the present invention for mechanically and / or manually manufacturing a double-walled drawer frame having an inner wall and an outer wall, wherein the inner wall and / or the outer wall has at least one first protrusion and at least one second protrusion, said method is performed in a particularly specified order and has the following method steps:

[0039] - A step in which at least one substantially plate-shaped spacer part is clamped between at least one first protrusion and at least one second protrusion,

[0040] - A step in which the outer wall is arranged parallel to the inner wall and connected to the inner wall.

[0041] Preferably, the outer wall and / or inner wall is arranged on at least one first protrusion and at least one second protrusion and is connected to the inner wall or the outer wall.

[0042] Preferably, at least one first protrusion and at least one second protrusion are arranged on the outer wall or on the inner wall prior to connecting the outer wall to the inner wall, and the following method steps may be provided:

[0043] - Steps for providing an exterior wall or an interior wall,

[0044] - A step in which at least one spacer part, particularly substantially plate-shaped, is clamped between at least one first protrusion and at least one second protrusion and fastened to an outer wall or an inner wall,

[0045] - Steps for providing inner or outer walls,

[0046] - A step in which the outer wall is arranged parallel to the inner wall and connected to the inner wall.

[0047] Accordingly, at least one spacer component can first be fastened to a first wall (an outer wall or an inner wall) having protrusions by clamping. Preferably, a second wall without protrusions can be arranged on a unit composed of the first wall and the spacer component in an additional step and connected thereto. An advantage of this embodiment is that the spacer component is already fastened to the first wall during the connection of the two walls and does not need to be held.

[0048] When connecting an outer wall and an inner wall, the following method steps may be provided:

[0049] - A step in which two walls are shifted relative to each other in a direction parallel to the length direction of the walls and / or across the length direction,

[0050] - The stage where two walls connect to each other during the shifting movement.

[0051] In a preferred exemplary embodiment of the method, at least one spacer component has a predetermined break point, preferably a perforation. The following method steps are preferably performed prior to at least one spacer component being clamped between at least one first protrusion and at least one second protrusion:

[0052] - A step in which at least one spacer component is fractured along a predetermined fracture point, particularly without a tool,

[0053] - A step in which a part of the spacer component is then used as a spacer component and clamped between at least one first protrusion and at least one second protrusion. Brief explanation of the drawing

[0057] At least one spacer part (4) can be clamped between at least one first protrusion (81) and at least one second protrusion (82).

[0058] In FIG. 1a, the first protrusion (81) and the second protrusion (82) extend along the entire length of the inner wall (2) and / or the outer wall (3). Additionally, the first protrusion (81) and the second protrusion (82) are arranged on two opposite long sides of the inner wall (2) and / or the outer wall (3). The spacer part (4) extends along the entire width of the inner wall (2) and / or the outer wall (3).

[0059] In particular, in this type of exemplary embodiment, the protrusions (81, 82) may also be used for connecting the outer wall (3) and the inner wall (2). The protrusions (81, 82) may also form the end faces of the double-wall drawer frame (1).

[0060] In FIG. 1b, the first protrusion (81) and the second protrusion (82) are arranged parallel to the long side of the inner wall (2) and / or the outer wall (3). However, the first protrusion and the second protrusion are not arranged on two opposite long sides, but are arranged within the plane of the inner wall (2) and / or the outer wall (3).

[0061] In FIG. 1c, the first protrusion (81) and the second protrusion (82) are arranged perpendicularly to the long side of the inner wall (2) and / or the outer wall (3). However, the first protrusion and the second protrusion are not arranged on the short side.

[0063] In FIG. 1e, the first protrusion (81) extends along the entire length of the inner wall (2) and / or outer wall (3) and is arranged on the long side of the inner wall (2) and / or outer wall (3). The second protrusion (82) is arranged parallel to the long side of the inner wall (2) and / or outer wall (3) and is arranged within the plane of the inner wall (2) and / or outer wall (3).

[0064] In FIG. 1f, two spacer parts (4) are provided. A first spacer part (4) is clamped between a first protrusion (81) arranged on a first short side and a second protrusion (82) aligned parallel to the first short side and arranged within the plane of the inner wall (2) and / or the outer wall (3). A second spacer part (4) is clamped between a first protrusion (81) arranged on a second short side opposite the first short side and a second protrusion (82) aligned parallel to the second short side and arranged within the plane of the inner wall (2) and / or the outer wall (3).

[0065] In FIG. 1g, two first protrusions (81) are provided, which are formed as angle brackets and hold the spacer part (4) on two opposite corners along the long side of the spacer part (4). A second protrusion (82) is arranged on the second long side of the spacer part (4).

[0066] In FIG. 1h, two spacer parts (4) are provided. A first spacer part (4) is clamped between a first first protrusion (81) arranged on the long side of the inner wall (2) and / or outer wall (3) and a second protrusion (82) arranged parallel to the long side and within the inner wall (2) and / or outer wall (3). A second spacer part (4) is clamped between a second first protrusion (81) arranged on the opposite long side of the inner wall (2) and / or outer wall (3) and a second protrusion (82) that also holds the first spacer part (4).

[0067] FIGS. 2a through 2d illustrate various exemplary embodiments of arrangements of at least one spacer part (4), at least one first protrusion (81), and at least one second protrusion (82) in particular, viewed parallel to the plane of the outer wall or inner wall along the longitudinal direction of the drawer frame (10).

[0068] At least one first protrusion (81) and / or at least one second protrusion (82) protrudes laterally from the inner wall (2) and / or outer wall (3).

Thus, the outer wall (3) is connected to the inner wall through at least one first protrusion (81) and at least one second protrusion (82).

[0073] The outer wall (3) is bent in the direction of the inner wall (2) while connected to the inner wall (2), so that the outer wall (3) or the inner wall (2) is placed in close contact with at least one clamped spacer part (4). Thus, noise generation is prevented despite the fact that the protrusions (81, 82) are taller than the spacer part (4).

[0074] FIGS. 3a through 6d illustrate preferred exemplary embodiments of a double-wall drawer frame (1).

[0075] In this exemplary embodiment, at least one first protrusion (81) and at least one second protrusion (82) are firmly, particularly integrally, connected to the inner wall (2) and are made of the same sheet metal as the inner wall (2).

[0076] The outer wall (3) is connected to the inner wall (2) through the first protrusion (81) and the second protrusion (82).

[0077] The spacer part (4) can be made of foam, particularly polyethylene foam, at least partially, preferably entirely, and is substantially shaped into a plate-like form. Thus, noise generation can be effectively prevented.

[0078] In particular, FIGS. 3a to 4b illustrate four steps for making a double-wall drawer frame (1).

[0079] In FIG. 3a, an inner wall (2) and a spacer part (4) having two protrusions (81 and 82) are provided.

[0084] In FIG. 5a, the outer wall (3) is arranged on the inner wall (2).

[0085] In FIG. 5b, the two walls (2, 3) are shifted relative to each other in a direction across the longitudinal direction of the walls (2, 3), so that the outer wall (3) engages with the guide groove (51) in the first protrusion (81).

[0086] Specifically, at least one guide ridge arranged on the outer wall (3) is inserted into at least one guide groove (51) arranged on the first protrusion (81). The at least one guide groove (51) grips around at least one guide ridge.

[0096] A guiding-in surface (53) for guiding the outer wall (3) transversely along the longitudinal direction of at least one guide groove (51) is adjacent to at least one guide groove (51).

[0097] The spacer part (4) is placed in close contact with the end edge of the guiding-in surface (53) while clamped.

[0098] The guide groove (51) and the guiding-in surface (53) are preferably formed from the same sheet metal part as the inner wall (2).

[0099] Guide ridges arranged on the outer wall (3) can be inserted into guide grooves (51). The guide ridges are shaped as substantially semicircular bends of a sheet metal part, preferably where the radius of at least one bend of the guide groove (51) is larger than the radius of at least one bend of the guide ridge. The guide ridges are made of the same sheet metal part as the outer wall (3) or the inner wall (2), preferably as end pieces of the outer wall (3).

[0100] The double-wall drawer frame (1) may include at least one holding device (7) for holding at least one guide groove (51) on at least one guide ridge (52).

[0101] FIG. 6d illustrates a detailed view of the area of ​​the second protrusion (82) where the space part (4) is placed in close contact.

[0102] The second protrusion (82) has a step-shaped form. The spacer part (4) is arranged in close contact with the first step (91) starting from the inner wall (2) while clamped.

[0104] Both of the steps (91 and 92) as well as the curved section (10) are made of the same sheet metal part as the inner wall (2).

[0105] A suspension ridge (62) for suspending the outer wall (2) may be arranged on a second protrusion (82), particularly a second step (92). The outer wall (3) may have a suspension groove (61) as a counterpart to suspend the outer wall (3) on at least one suspension ridge (62). At least one suspension groove (61) may be formed as a bent end piece of the outer wall (3).

[0106] FIG. 7a illustrates a top view of a drawer frame (1) having no outer wall (3) and a spacer part (4). In this drawing, it can be clearly seen that the spacer part (4) covers at least 1 / 4 of the surface area of ​​the inner wall (2).

[0107] Fig. 7b shows a cross-section through Fig. 7a.

[0108] FIG. 7c illustrates a detailed view of a portion of the first protrusion (81) within the area where the space part (4) is placed in close contact. This is the end edge of the guiding-in surface (53) of the first protrusion (81).

[0109] FIG. 7d illustrates a detailed view of a portion of the second protrusion (82) within the area where the spacer part (4) is placed in close contact. The spacer part is placed in close contact with the curved portion (10), where the curved portion (10) is preferably arranged on the first step (91) of the second protrusion (82).

[0110] FIG. 8a illustrates an alternative exemplary embodiment of the drawer frame (1). Compared to the exemplary embodiments of FIG. 3a through FIG. 7d, the drawer frame (1) is narrower and consequently relatively longer. Also, in this exemplary embodiment, a spacer part (4) is clamped between a first protrusion (81) and a second protrusion (82), wherein the first protrusion (81) and the second protrusion (82) are also formed for connection to an outer wall (3).

[0111] The spacer part (4) has a predetermined breaking point (18), preferably a perforation. By this, the spacer part (4) can be divided, and drawer frames (1) having different dimensions can be used.

[0112] FIG. 8b illustrates an alternative exemplary embodiment having different dimensions. In particular, the drawer frames are formed to be shorter and wider than those shown in FIG. 8a. Thus, the spacer part (4) of FIG. 8a is too long compared to the drawer frame (1) of FIG. 8b, but has an appropriate width.

[0113] The spacer part (4) (Fig. 8a) can be broken along a predetermined break point (18) without a tool. A portion of the spacer part (4) is then used as a spacer part (4) and clamped between at least one first protrusion (81) and at least one second protrusion (82).
