Description

The present invention relates to a refrigerated goods container for use in a refrigerator, in particular for use as a drawer, which can be pulled out of a compartment in the body of the refrigerator in order to access its contents.

There are refrigerated goods containers, in particular wire baskets, which have a frame at their upper edge. A frame for a refrigerated goods container is for example made of flat steel, to which the ascending wires of the grid are attached. It is cumbersome for the user to handle the wire basket over such a frame, on the one hand, because the narrow cross section of the flat steel when pulling out a fully loaded basket unpleasant cuts in the fingers, on the other hand, because the steel at the temperatures usual for a freezing compartment The fingers cool in a painful way and may even freeze the skin on the steel. Therefore, the frame is conventionally clad by plastic profiles, which offer the fingers a larger contact surface and dissipate the heat less. These profiles are bolted to the frame. For this purpose, screw holes in the frame and in the profile must be positioned exactly to each other, which brings high demands on the manufacturing accuracy with it. The welding of the frame to the wires of the grid is expensive.

Object of the present invention is to provide a refrigerated goods, which is easier and cheaper to manufacture, while good handling is given to a user.

The object is solved by the features of the independent claim. Preferred embodiments are given in the appended claims.

One aspect relates to a refrigerated goods container for a refrigeration appliance, with at least one wall and one end profile. The wall has an end portion. The end profile is mounted on the end section. A first side surface of the end portion includes first locking projections. A second side surface of the end portion includes at least a second latching projection. The first side surface is the second side surface across from. The end profile is latched to the first latching projections and the second latching projection.

Preferably, at least one wall is made of a wire mesh. The end portion may be a top edge of the wall with the end profile mounted to the top of the wall.

A refrigerated goods container comprises in particular a floor and walls. If a refrigerated goods container is designed as a shell, the refrigerated goods container preferably comprises a bottom and four walls, namely a front wall, a rear wall and two side walls. Furthermore, a refrigerated goods container may comprise a bottom and three walls, namely a rear wall and two side walls. The walls extend in particular from the ground in a height direction.

The refrigerated goods container may in particular be a tray and / or a door rack in a refrigeration appliance.

Furthermore, at least one first wire may be attached to the first side surface of the end portion. In particular, the first wire may be attached horizontally to the first side surface. The first latching projections may be formed by deformations of the first wire. The first wire may be a corrugated wire in a horizontal plane. According to one embodiment, the corrugated wire can engage in an undercut of the end profile.

In particular, the first latching projections may be shaped as shaft sections. Preferably, the shaft portions may have different shapes, for example, substantially triangular and / or substantially rectangular and / or substantially sinusoidal.

Further preferably, the first wire may have different cross-sectional shapes, for example, round, rectangular, polygonal.

In the case of a wire grid, the first wire or corrugated wire may be fastened in the same way as all the other wires of the wire grid. Typically, at a wire mesh intersecting wires pressed against each other and spot welded. Advantageously, no separate manufacturing step is required on a wire grid for the attachment of the first wire. Advantageously, a firm, positive connection between the end profile and wire basket can be achieved by engaging in an undercut of the end profile. Further advantageously, this only a low manufacturing accuracy is required.

Alternatively or additionally, the first latching projections are formed by forming the wall. For example, the wall may be based on plate-shaped material, wherein the first locking projections are formed by stamping and bending the sheet or are formed by bending the upper edge of the wall or the end portion. If the wall of wire mesh, for example, wires of the wire mesh can be bent and form the first locking projections.

According to one embodiment, a first latching projection may be arranged between two rectilinear sections of the first wire. In other words, a rectilinearly extending section may be arranged next to each first latching projection.

Preferably, the extent of the first latching protrusion measured along the end portion is shorter than that of the rectilinear portions.

In a corrugated wire, a shaft portion may be disposed between two straight portions, the straight portions being fixed to wires of a wire mesh, and the wave portion projecting with respect to the wires of the wire mesh. The shaft section preferably engages in the undercut of the end profile. The extent of the shaft portion measured along the upper edge is preferably shorter than that of the straight-line portions. Advantageously, this can produce a sufficiently strong connection to a large number of wires of the grid.

In particular, the second wire may have different cross-sectional shapes, for example, round, angular, polygonal.

Preferably, the first latching projections project further from the first side surface than the second latching projection from the second side surface. In other words, the first locking projections protrude further from the first side surface than the second locking projections from the second side surface.

Preferably, the first latching projections and the second latching projection are offset from one another in a height direction.

More preferably, the first locking projections are arranged higher in the height direction than the at least one second locking projection.

At least one wall of the refrigerated goods container preferably has a wire grid. Preferably, the first wire is attached to wires of the wire grid.

In particular, a wire mesh comprises intersecting wires. In particular, crossing wires may be arranged substantially orthogonal to each other and / or form a diamond pattern. In particular, crossing wires run diagonally or obliquely to the height direction.

Preferably, the first latching projections engage in an undercut of the end profile.

Preferably, the length of the straight sections of the first wire is greater than the length of the distance between the wires of the wire screen crossing the first wire.

Preferably, the first wire is attached to wires of the wire grid.

Preferably, the first wire is attached to vertically extending wires of the wire grid. Alternatively or additionally, the first wire may be attached to obliquely to the height direction or diagonal wires.

Advantageously, if necessary, it can be achieved that even if the length of the first locking projection of the first wire is not an integer multiple of the distance between the wires of the wire mesh, each rectilinear portion can be fastened to at least one wire of the wire mesh. Advantageously, as a result, the demands on the accuracy in forming the first locking projections can be reduced.

Preferably, the extent of the first latching protrusion measured along the end section is smaller than the distance between two adjacent wires of the wire mesh.

In particular, the extent of the shaft section measured along the upper edge can preferably be smaller than the distance between two adjacent wires of the wire grid. For example, if a shaft portion completely fits between two wires of the grid, both wires may be welded to the corrugated wire. If a shaft portion overlaps with a wire of the grid, at least the mutually adjacent wires of the grid may be attached to straight portions of the corrugated wire to obtain maximum strength.

Preferably, the end profile surrounds the first latching projections and the second latching projection.

In particular, on a side opposite the corrugated wire side of the wire grid, the second wire may be attached as an auxiliary wire. In particular, such an auxiliary wire can stabilize such wires of the grid which can not be connected to the corrugated wire because they overlap with a wave portion.

Preferably, the end profile has a groove. The groove preferably has a first side wall and a second side wall. The groove preferably receives the end portion of the wall.

Preferably, the groove is a downwardly open groove.

Preferably, the second groove base portion together with the second side wall forms a receiving area for wires of a wire grid.

Preferably, the depth of the undercut is greater than the radius of the first wire. In particular, in non-round or incomplete wires, an equivalent or approximation for the radius can be used. In particular, in rectangular wires, the key width can be assumed or the radius of an outer circle would encompass the rectangular wire.

Preferably, the depth of the groove is greater than the radius of the first wire.

Advantageously, when the depth of the groove or undercut is greater than the radius of the corrugated wire, the corrugated wire can be securely held in the undercut when gripping and lifting the refrigerated goods container at the end profile.

The second side wall preferably has a rib engaging under the second latching projection.

Preferably, the end profile can be mounted by the rib by the end profile initially placed in an oblique orientation to the top of the grid and thereby the first locking projections are introduced substantially without deformation of the end profile in the undercut and then the end profile by a by the intervention of first latching projections pivoting axis defined in the undercut is pivoted to bring the rib under the second latching projection in engagement.

Preferably, a lower edge of the first side wall is lower than a lower edge of the second side wall.

Advantageously, it can thereby be achieved that, when the refrigerated goods container is gripped and lifted on the end profile, the weight of the refrigerated goods container predominantly acts or acts on the first side wall of the groove. Advantageously, such a tilting back of the end profile about a pivot axis of the end profile and consequently a release of the locking between the second side wall of the groove and the second locking projection can be further counteracted.

Adjacent walls of the refrigerated goods container preferably have end profiles. In other words, one or more walls of the refrigerated goods container may have end profiles. Preferably, end profiles adjoining walls or adjacent walls are connected by angle pieces. In particular, the angle pieces can be inserted angle pieces which are connected to the end profiles.

Advantageously, by means of the angle pieces, a further attachment or securing of the end profiles can be achieved.

Fig. 1 and 2 show a refrigerated goods container 1, once completely with end profiles 2 and without end profiles 2. According to this embodiment, the refrigerated goods container is designed as a wire basket. The proportions of the refrigerated goods are those of a pull-out box, as it can be pulled out, for example, in the body of a freezer. A refrigerated goods container with the features described below could also be used as a hanging basket in a freezer or as a suspended on the inside of a refrigerator door door racks.

The refrigerated goods container 1 according to this embodiment substantially in the form of a cuboid with an open top. However, other shapes may be used. Floor 3, side walls 4, front and rear walls 5, 6 of the refrigerated goods container 1 are made in this example of a wire mesh.

According to this example, the wires 7, 8 of the wire grid are arranged in two intersecting layers and are welded together at the intersections. From the wire mesh a flat, approximately cross-shaped cut is first cut out. At the same time as the cutting, at the ends of the four arms of the cross, it is possible to form cranks 9 at the free ends of the wires 7, 8.

On the side walls 4 joints 10 can be seen, where the horizontally extending wires are interrupted. The joints 10 are due to the fact that two opposite arms of the cross are wider than the front and rear walls 5, 6 and the other two narrower than the side walls 4, so that, to form the side walls 4, on the one hand, the narrow arms are folded up, to form a central portion 11 of the side walls, the wide arms are folded up to form front and rear walls 5, 6 and laterally over the bottom 3 projecting edge portions of the wide arms are folded a second time to front and rear edge portions 12, 13th the side walls 4 to form.

In order to stiffen the box thus formed in this case, another wire 14 at the free ends of the towering wires of the walls 4, 5, 6, the joints 10 bridging secured. Along the rear wall 6 of this wire 14 is rectilinear. According to the embodiment according to Fig. 2 the wire 14 is a first wire. This first wire has straight-line sections 15 and first latching projections 16 along the other walls 4, 5. The straight sections 15 and the first locking projections 16 are arranged side by side and therefore alternate. The first latching projections 16 protrude from the walls 4, 5 or from the walls 4, 5. The first latching projections 16 are formed as shaft sections 16 in this embodiment.

In the presentation of the Fig. 2 At each rectilinear portion 15, five wires 8 of a side wall 4 or four wires of the front wall 5 are fixed, and the shaft portions 16 are respectively placed in the space between two such wires, so that all the vertical wires 7, 8 of the walls 4, 5, 6 with the wire 14 are connected. It may be provided according to other embodiments, other numbers of wires.

In practice, there may be shifts between the wires 7, 8 and the shaft sections 16, so that the in Fig. 3 shown situation may occur that a wire 7,8 overlaps with a shaft portion 16 and therefore can not be attached to the wire 14. The stability of the wire basket is not fundamentally endangered thereby.

On the inner sides of the side walls 4 and the front wall 5, a second locking projection 17 is provided just below the wire 14 and parallel to this. The second locking tab 17 is provided here as a wire or auxiliary wire. The second latching pretension 17 or auxiliary wire may have a smaller diameter than the wires 7, 8, 14.

Fig. 3 shows an end portion 34 or top edge of a wall plugged or fixed end profile 2 in section.

Preferably, the end profile 2 has a constant cross section over its length and can therefore be manufactured inexpensively by extrusion.

The end profile 2 comprises a first side wall 18 and a second side wall 19. The first and second side walls 18, 19 are preferably mutually parallel outer and inner walls 18, 19. A ceiling wall 20 connects the walls 18 and 19th

The end profile 2 has a groove 23 which comprises a groove base 37 with a first groove base portion 37a and a second groove base portion 37b. The second groove base portion 37b is higher in the height direction than the first groove base portion 37a.

The first groove base portion 37a forms at least one undercut 25 together with the first side wall 18 and a projection 24. This undercut 25 receives the first latching projections 16.

The second groove base portion 37b, together with the second side wall 19, forms a receiving area 38 which receives end pieces of the wires 7 of the wire basket.

According to this embodiment, the end profile 2 additionally comprises an intermediate wall 21, which forms the groove base 37. According to another embodiment, the groove bottom a ceiling wall may be formed.

In this example, the intermediate wall 21 together with the top wall 20 forms a cavity 22. Under the intermediate wall 21 projecting portions of the first side wall and the second side wall 18, 19 define the groove 23. At the groove 23 facing inside of the first side wall 18 is the projection 24 of eg shaped triangular cross-section. A horizontal upper side of the projection 24, together with the intermediate wall 21, defines the undercut 25 into which the first latching projections 16 of the wire 14 engage. The depth of the undercut 25 is greater than the radius of the wire 14, so that when the end profile 2 is raised, the wire 14 rests more stably on the horizontal top of the projection 24. A lower edge 26 of the outer wall 18 is preferably reinforced to improve the resistance of the end profile 2 to shocks.

The intermediate wall 21 has a stepped course; formed by the first and second groove base portions 37a, 37b.

According to this embodiment, the first groove base portion 37a is located on the first locking projections 16, which are formed here as shaft portions, and the straight portions 15 of the wire 14; the second groove base portion 37b extends at a higher level and forms, with the second side wall 19, the receiving portion 38 into which tips of the vertical wires 7 projecting beyond the wire 14 can engage, preferably without abutting the intermediate wall 21.

The second side wall 19 has a rib 28 projecting into the groove 23. According to this example, the rib 28 is arranged on the lower edge 27 of the second side wall 19. The rib 28 and the second latching projection 17 touch each other on an inclined tangent plane 29. When the end profile 2 is pivoted counterclockwise about a pivot axis 30 defined by the engagement of the first latching projections 16 in the undercut 25, the rib 28 passes the second latching projection 17, and the end profile 2 reaches a position in which, without being deformed, it can be moved sideways, so that the first locking projections 16 from the groove 25 disengage. In this position, it can be lifted off the wall 5. The installation of the end profile 2 on the wall 5 is carried out by the reverse movement.

According to FIG. 4 For example, corner pieces 31 may be provided which connect the end profile 2 of the front wall 5 with those of the side walls 4. The corner pieces 31 each have an approximately cuboid main body 32, projecting from the pins 33 on two sides. At each end of the end profile 2 of the front wall 5, a corner piece 31 is mounted by inserting a pin 33 into the cavity 22. The end profiles 2 of the side walls 4 are slightly shorter than the side walls 4, so that over the upper edges of the side walls 4 extending pins 33 of the two corner pieces 31, the attachment of the end profiles 2 does not interfere there. Once the end profiles 2 on the side walls 4 are correctly aligned, they can be displaced along the side walls 4, so that the pins 33 engage in their cavities 22. When this is done, none of the end profiles 2 can pivot more, and the end profiles 2 are securely anchored to the wire basket 1.

Furthermore, additional locking hooks and / or latching means may be provided on the end profile 2, with which the end profile 2 on a wall (4, 5) or at least one wire (7, 8) can be additionally attached.
