Description

Container for cooling material

Technical Field

The invention relates to a container for cooling material for use in a refrigerator

The cooler container is used in particular as a pull-out box, which can be pulled out of a compartment in the body of the refrigerator for gripping the contents of the cooler container.

Background

There are the following chill containers: the cooling container is in particular a wire frame, which has a frame (Rahmen) on its upper edge. The frame for the container for the cooling material consists, for example, of flat steel, to which the ascending wires of the grate are fastened. It is difficult for the user to manipulate the wire frame by such a frame: on the one hand, because the narrow cross section of the flat steel can cut into the finger undesirably when the fully loaded frame is pulled out, and on the other hand, because the steel cools the finger in a painful manner at the usual temperature of frost and may even be able to freeze the skin on the steel. It is customary to wrap the frame with a plastic profile which provides the fingers with a larger contact surface and leads the heat away less strongly. These profiles are screwed to the frame. For this purpose, the threaded holes in the frame and in the profiles must be precisely positioned relative to one another, which entails high demands on the production accuracy. Welding the frame to the wires of the grid is also costly.

Disclosure of Invention

The object of the present invention is to provide a cooler container which can be produced more simply and advantageously, while at the same time providing good handling for the user.

This object is achieved by the features of the independent claims. Preferred embodiments are specified in the dependent claims.

One aspect relates to a cooler container for a refrigeration appliance as follows: the chill container has at least one wall and has a terminal profile (absclussprofile). The wall has an end section. The end profile is mounted on the end section. The first side of the end section includes a first latch tab. The second side of the end section comprises at least one second latching projection. The first side is opposite to the second side. The terminal profile is latched by means of a first latching projection and a second latching projection.

Preferably, at least one wall is constituted by a grid of wires. The end section can be an upper edge of the wall, wherein the end profile is mounted on the upper edge of the wall.

The chill container comprises, inter alia, a bottom and a wall. If the chill container is designed as a shell (Schale), the chill container preferably comprises a base and four walls, namely: a front wall, a back wall and two side walls. Furthermore, the chill container can comprise a bottom and three walls, namely: a back wall and two side walls. These walls extend in particular in the height direction from the bottom.

The chill container can be, in particular, a housing and/or a door shelf in a refrigeration appliance.

Furthermore, the at least one first wire can be fastened on the first side of the end section. In particular, the first wire can be fastened horizontally on the first side. The first latching projection can be formed by deformation (Verformung) of the first wire. The first wire can be a wire that is wavy in a horizontal plane. According to one embodiment, the wires in the form of a wave can be fitted into the undercut (hinderschneidung) of the terminal profile.

In particular, the first latching projection can be shaped as a wave-shaped section. Preferably, the wave-shaped sections can have different shapes, for example: substantially triangular and/or substantially rectangular and/or substantially sinusoidal.

Furthermore, the first wire can preferably have different cross-sectional shapes, for example circular, rectangular, polygonal.

In the case of a wire grid, a first wire (or a wire in a wave form) can be fastened in the same way as all the other wires of the wire grid. Typically, in the case of wire grids, wires that intersect each other are pressed against each other and spot welded. Advantageously, no special production steps are required on the wire grid for the fastening of the first wire. Advantageously, by fitting into the undercut of the terminal profile, a firm, form-fitting connection between the terminal profile and the wire frame can be achieved. Furthermore, advantageously, only a low production precision is required for this purpose.

Alternatively or additionally, the first latching projection is formed by a reshaping of the wall (umform). For example, the wall can be based on a plate-shaped material or a sheet material, wherein the first latching projection is formed by stamping and bending the plate material (or sheet material) or by bending an upper edge or end section of the wall. If the wall is formed by a wire grid, for example, the wires of the wire grid can be bent and form the first latching projections.

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

Preferably, the extent of extension (ausdehhnung) of the first detent projection measured along the end section is shorter than that of a straight section.

In the case of wires in the form of a wave, a wave section can be arranged between two straight sections, wherein these straight sections are fastened to the wires of the wire grid and the wave section projects with reference to the wires of the wire grid. The wave-shaped section preferably fits into the undercut of the terminal profile. The extent of the wave-shaped section measured along the upper edge is preferably shorter than that of a straight section. Advantageously, a sufficiently strong connection structure for the plurality of wires of the grid can thereby be established.

According to an embodiment, the second wire can be fastened on the second side of the end section. Preferably, the second wire is an at least substantially horizontally oriented wire. Preferably, the second wire forms at least one second latching projection.

Alternatively or additionally, the second latching projection can be formed by a modification of the wall. For example, if the wall is based on a sheet material or a plate material or a sheet material, the second latching projection can be formed by bending the upper edge or end section of the wall or can be produced by stamping and bending the wall. If the wall is formed by a wire grid, it is possible, for example, to bend the wires of the wire grid and form the second latching projections.

In particular, the first detent projection and/or the second detent projection can be formed as a projection formed from the wall material or as a detent projection by stamping and bending.

In particular, the second wire can have different cross-sectional shapes, for example circular, angular, polygonal

Preferably, the first latch projection projects further from the first side than the second latch projection projects from the second side. In other words, the first latch tab extends further from the first side than the second latch tab extends from the second side.

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

Further preferably, the first latching projection is arranged higher in the height direction than the second latching projection.

Preferably, at least one wall of the chill container has a wire grid. Preferably, the first wire is fastened to the wires of the wire grid.

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

Preferably, the first latching projection engages into a undercut of the terminal profile.

Preferably, the length of the straight section of the first wire is greater than the length of the spacing between those wires of the wire grid which intersect the first wire.

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

Preferably, the first wire is fastened to a vertically running wire of the wire grid. Alternatively or additionally, the first wire can be fastened to a wire running obliquely or diagonally to the height direction.

Advantageously, this can be achieved if possible: even when the length of the first latching projections of the first wire is not a multiple integer multiple of the spacing between the wires of the wire grid, each straight section can be fastened on at least one wire of the wire grid. Advantageously, this reduces the precision required for forming the first latching projection.

Preferably, the extent of the first detent projection measured along the end section is smaller than the distance between two mutually adjacent wires of the wire grid.

In particular, the extent of the wave-shaped section measured along the upper edge can preferably be smaller than the distance between two wires of the wire grid adjacent to each other. Thus, for example, when the wave-shaped section is located completely between two wires of the grid, the two wires can be welded to the wires in the wave shape. When the wave-shaped section overlaps a wire of the grid, then at least the wires of the grid adjacent on both sides can be fastened on the straight sections of the wire in wave form in order to obtain maximum strength.

Preferably, the terminal profile encompasses (umgreift) the first latching projection and the second latching projection.

In particular, the second wire as an auxiliary wire can be mounted on the side of the wire grid opposite to the wires in the wave shape. Such auxiliary wires are particularly capable of stabilizing the wires of the grid as follows: these wires cannot be connected with wires in a wave shape because the wires overlap with the wave-shaped section.

Preferably, the termination profile has a groove. The trough preferably has a first side wall and a second side wall. The groove preferably receives an end section of the wall.

Preferably, the slot is a downwardly open slot.

The first latching projection preferably engages in at least one undercut in the groove. Preferably, the undercut of the termination profile is formed by a groove in the groove. Furthermore, the first side wall preferably has at least one projection on which the first latching projection rests.

The terminal profile preferably comprises a top wall, which is connected to the first side wall and the second side wall.

The end profile preferably comprises a groove base. Preferably, the groove base is of stepped design.

Preferably, the groove base has a first groove base section and a second groove base section.

Preferably, the first groove bottom section is deeper in the height direction than the second groove bottom section.

Preferably, the first groove bottom section forms together with the first side wall and the projection on the first side wall at least one undercut for the first latching projection.

Preferably, the second trough bottom section forms together with the second side wall a receiving area for the wires of the wire grid.

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

In particular, the use of an equivalent radius is possible in the case of wires which are not round or incomplete

Or approximation of

The wrench opening width can be used, in particular in the case of rectangular wire(schlusselwite), or a radius around the outer circle of the rectangular wire.

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

Advantageously, if the depth of the groove (or undercut) is greater than the radius of the corrugated wire, this corrugated wire can be reliably held in the undercut when the chill container is gripped and lifted on the end profile.

Preferably, the second side wall has a rib that engages under the second latch projection.

Preferably, the terminal profile can be assembled by means of the ribs in that: the terminal profile is first placed on the upper edge of the grid in an inclined orientation, and the first latching projection is introduced into the undercut without substantial deformation of the terminal profile, and the terminal profile is then pivoted about a pivot axis defined by the engagement of the first latching projection into the undercut, in order to bring the rib into engagement below the second latching projection.

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

Advantageously, this can be achieved by: when the cooler container is gripped and lifted on the end profile, the weight of the cooler container acts for the most part on the first side wall of the trough or on the first side wall of the trough. Advantageously, it is thereby possible to further counteract: the end profile is folded back about the pivot axis of the end profile, so that the latching mechanism between the second side wall of the groove and the second latching projection is released.

Preferably, the mutually adjoining walls of the chill container have a terminal profile. In other words, one or more walls of the chill container can have a terminal profile. Preferably, the end profiles of the walls adjoining one another (or of adjacent walls) are connected to one another by corner fittings (winkelsstuck). In particular, the corner pieces can be inserted corner pieces which are connected to the end profile.

Advantageously, a further fastening or fixing of the termination profile can be achieved by means of the corner pieces. In particular, the risk of tilting back can be reduced if the end profiles inserted into the mutually intersecting (or mutually adjoining) walls of the cooler block are connected by corner pieces inserted into the end profiles.

Preferably, the end profile has a receptacle. Preferably, the corner piece has a tenon (Zapfen). Preferably, these tenons fit into the receiving portions of the terminal profiles.

Preferably, the end profile is designed as a hollow profile.

Another aspect of the invention relates to a method for fitting a terminal profile to a wall of a cooler container for a refrigerator, which has at least one wall and a terminal profile. The wall has an end section. The end profile is mounted on the end section. The first side of the end section includes a first latch tab. The second side of the end section comprises at least one second latching projection. The first side is opposite to the second side. The terminal profile is latched by means of a first latching projection and a second latching projection. Preferred steps of the method result from the description of the first aspect and the described embodiments.

In a similar manner, a method for producing a chill container according to the first aspect and the respective preferred embodiments is proposed.

Drawings

Further features and advantages of the invention result from the following description of an embodiment with reference to the drawings. Wherein:

FIG. 1: the cooling medium container according to the invention with the end profile is shown in a perspective view;

FIG. 2: showing the chills container without the finish profile;

FIG. 3: a part of the wall of the cooling container is shown partly in section and partly in perspective; and

FIG. 4: a corner of the refrigerated container.

Detailed Description

Fig. 1 and 2 show a cooler container 1 which is provided in one piece with a terminating profile 2 and without a terminating profile 2. According to a variant, the cooling container is configured as a wire frame. The dimensional ratio of the refrigerated goods container is the dimensional ratio of a pull-out box which can be supported, for example, in a withdrawable manner in the body of the freezer. However, the refrigerated goods container with the features described below can also be used as a rack in a freezer or as a door shelf on the inside of a door of a refrigeration appliance.

According to this embodiment, the cooling object container 1 has substantially the shape of a rectangular parallelepiped with an open upper side. However, other shapes can be used. The bottom 3, the side walls 4, the front wall 5 and the rear wall 6 of the cooler container 1 are produced in this example from a wire grid.

According to this example, the wires 7, 8 of the wire grid are arranged in two mutually crossing positions and welded to each other at the crossing points. A flat, almost cruciform cut is first cut out of the wire grid. Simultaneously with the cutting out, bent portions 9 can be formed on the free ends of the wires 7, 8 at the ends of the four limbs of this cross.

On these side walls 4, a seam 10 can be seen, at which seam 10 the horizontally running wire is interrupted. These seams 10 thus result in: the two opposite legs of the cross are wider than the front wall 5 and the rear wall 6 and the other two legs are narrower than the side walls 4, so that, to form the side walls 4, the narrow legs are turned up on the one hand to form the middle sections 11 of the side walls, the wide legs are turned up to form the front wall 5 and the rear wall 6, and the edge sections of the wide legs which project laterally beyond the bottom 3 are turned over a second time to form the front edge sections 12 and the rear edge sections 13 of the side walls 4.

In order to stiffen the box thus formed itself, a further wire 14 is fastened in this case to the free ends of the up (autofinged) wires of the

walls

4, 5, 6 in such a way that the seam 10 is bridged. The wire 14 runs straight along the back wall 6. According to the embodiment according to fig. 2, the wire 14 is a first wire. The first wire has a straight section 15 and a first latching projection 16 along the other walls 4, 5. The straight sections 15 and the first latching projections 16 are arranged side by side and alternate. The first latching projection 16 projects from the wall 4, 5 or projects from the wall 4, 5. In this embodiment, the first latching projection 16 is designed as a wave-shaped section 16.

In the illustration of fig. 2, five wires 8 of the side wall 4 or four wires of the front wall 5 are fastened on each straight section 15, and the wave-shaped sections 16 are each placed in the intermediate space between two such wires, so that all the vertical wires 7, 8 of the

walls

4, 5, 6 are connected with the wire 14. According to other embodiments, other numbers of wires can be provided.

In practice, a movement can occur between the wires 7, 8 and the wave section 16, so that the situation shown in fig. 3 can also occur: a wire 7, 8 overlaps a corrugated section 16 and can thus not be fastened to the wire 14. The stability of the wire frame is thus not impaired in principle.

On the inner side of the side walls 4 and the front wall 5, a second latching projection 17 is provided slightly below the wire 14 and parallel to the wire 14. Here, the second latching projection 17 is provided as a wire or an auxiliary wire. The secondary detent projections 17 or the auxiliary wires can have a smaller diameter than the wires 7, 8, 14.

Fig. 3 shows the end profile 2 in a sectional view, which is plugged onto or fastened to an end section 34 (or upper edge) of a wall.

Preferably, the end profile 2 has a constant cross section over its length and can thus be produced cost-effectively by extrusion.

The termination profile 2 comprises a first side wall 18 and a second side wall 19. The first side wall 18 and the second side wall 19 are preferably an outer wall 18 and an inner wall 19 that are parallel to each other. A top wall 20 connects these

walls

18 and 19.

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

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

The second groove bottom section 37b forms together with the second side wall 19 a receiving region 38, which receiving region 38 receives an end section of the wire 7 of the wire frame.

According to this embodiment, the terminal profile 2 additionally comprises an intermediate wall 21, which intermediate wall 21 forms a groove base 37. According to other embodiments, the trough bottom can form a top wall.

In this example, the intermediate wall 21 forms together with the top wall 20 a hollow space 22. The regions of the first side wall 18 and the second side wall 19 that project below the intermediate wall 21 bound the groove 23. On the inner side of the first side wall 18 facing the groove 23, a projection 24, for example of triangular cross section, is formed. The horizontal upper side of the projection 24 delimits, together with the intermediate wall 21, a undercut 25, into which undercut 25 the first latching projection 16 of the wire 14 engages. The depth of the undercut 25 is greater than the radius of the wire 14, so that the wire 14 rests more stably on the horizontal upper side of the projection 24 when the terminal profile 2 is lifted. The lower edge 26 of the outer wall 18 is preferably reinforced to improve the resistance of the termination profile 2 to impacts.

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

According to this embodiment, a first groove bottom section 37a is disposed on the first detent projection 16 (here the first detent projection 16 is shaped as a wave section) and the straight section 15 of the wire 14; the second groove base section 37b runs to a higher height level (Niveau) and forms with the second side wall 19 a receiving region 38 into which a tip of the vertical wire 7 protruding beyond the wire 14 can be fitted, preferably without impinging on 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 secondary detent projection 17 touch each other in an inclined tangential plane 29. When the terminal profile 2 is pivoted in the counterclockwise direction about the pivot axis 30 defined by the engagement of the first detent projection 16 into the undercut 25, the rib 28 passes the second detent projection 17 and the terminal profile 2 reaches the following state: in this state, the terminal profile 2 can be moved laterally without deformation, so that the first latching projections 16 disengage from the grooves 25. In this state, the end profile 2 can be removed from the wall 5. The mounting of the end profile 2 on the wall 5 takes place by means of a reverse movement sequence.

According to fig. 4, for example, corner pieces 31 can be provided, which corner pieces 31 connect the end profiles 2 of the front wall 5 to the end profiles of the side walls 4. The corner pieces 31 each have a body 32 of almost right-angle parallelepiped shape, in which body 32 a tenon 33 is protruded on both sides. On each end of the terminal profile 2 of the front wall 5, the corner piece 31 is fitted by pushing the tenon 33 into the hollow space 22. The end profile 2 of the side wall 4 is slightly shorter than the side wall 4, so that the tenons 33 of the two corner pieces 31 extending above the upper edge of the side wall 4 do not hinder the installation of the end profile 2 there. As soon as the end profile 2 is correctly oriented on the side wall 4, the end profile 2 can be moved along the side wall 4, so that the tongue 33 engages into the hollow space 22 of the end profile 22. When this happens, then the end profiles 2 can no longer swing and the end profiles 2 are securely anchored to the wire frame 1.

Furthermore, latching hooks and/or latching means can be additionally provided on the end profile 2, by means of which latching hooks and/or latching means the end profile 2 can be additionally fastened to a wall (4, 5) or to at least one wire (7, 8).
