    DRAWER, REFRIGERATION APPLIANCE USING THIS DRAWER AND TRANSPORT CONTAINER FOR THE SAME
    DESCRIPTION
    The present invention relates to a drawer for a refrigeration apparatus, a refrigeration apparatus, in which a drawer of this type is used as well as a transport container for supplying a manufacturer of refrigeration apparatus with drawers to be used in these.
    The drawers for refrigeration devices are conventionally manufactured most of the time in the form of integral plastic trays in the injection molding. A plurality of such integral drawers can be fitted together, so that their transport from a supplier to a manufacturer of domestic refrigeration appliances, which assembles them in the appliances manufactured by it, requires a lot of transport volume and causes freight costs correspondingly high. Also the storage of drawers in the manufacturer requires a lot of storage space and is correspondingly expensive.
    A drawer for a refrigeration apparatus with a pivotable wall element is known from document EU2004 / 104504A1. The pivotable wall element is here a front wall element that when the drawer is mounted in a refrigeration apparatus, can be folded around an articulation axis that extends along its lateral edge, to gain access to the interior from the drawer, without it being removed from the refrigeration apparatus. The remaining wall elements and a bottom element form a rigid unit, so that a reduction in the need for space cannot be achieved through the folding of the front wall element. Therefore, supply and storage are also expensive in this drawer.
    The purpose of the present invention is to create a drawer for a refrigeration apparatus, which allows an economical supply and storage, space saving in the manufacturer of refrigeration apparatus.
    The task is solved because in a drawer for a refrigeration device with a bottom element and four wall elements, at least three of the wall elements and the bottom element are joined together by hinges and the at least three Wall elements are pivotable between a vertical position and a flat positioned position, in which they are adjacent to each other or next to the bottom element. In the corduroy position, the attached wall elements

    with each other and with the background element they can be easily stacked and saving space and thus allow efficient, economical transport and cost-effective storage. To be able to mount the drawer in a refrigeration device, you just have to bring the wall elements to their vertical position and tie them together.
    The wall and bottom elements can be formed integrally or they can be joined together by means of laminated hinges. This enables an economical fabrication of all the elements joined together in the drawer with a unique molding tool that can be economically performed by virtue of its flat configuration.
    Preferably, the sheet hinges connect, respectively, one of the at least three wall elements with the bottom element. In fact, it is also possible to connect wall elements to each other by means of the sheet hinges, but for the load capacity of the drawer in use it is more favorable that the sheet hinges have a length as large as possible and in practice the lower edges adjacent to the background element of the wall elements are most often longer than the side edges, in which the wall elements are adjacent to each other.
    A front wall element may be manufactured separately from the other wall elements and the background element. A separation of this type makes it possible, on the one hand, a space-saving transport, which is explained more precisely below; on the other hand, in this way a configuration is also possible a configuration of the front wall element, which differs from the remaining wall elements and the background element, for example with respect to color, material or the like.
    In particular, the front wall element can be kept transparent to give a user the vision inside the drawer, when the drawer is mounted in a refrigeration apparatus, without having to be removed for that purpose outside the refrigeration apparatus.
    To facilitate the extraction of the drawer out of the refrigeration apparatus, grip openings can also be provided in two lateral elements of the drawer wall.
    To ensure the joint retention of the wall elements in the vertical position, two lateral elements of the wall may have reinforcing profiles on their front edge, which are surrounded by lateral ribs

    of the front wall element. Such a structure allows a secure placement of the front wall element through the mooring on the front edges of the side wall elements and, if necessary, the bottom element.
    Alternatively, two side elements of the wall may have grooves, in which the marginal edges of the front element of the wall fit, when the wall elements are in the vertical position. Such structure allows through the simple elevation of the side elements of the wall to connect the front element of the wall manufactured separately with the remaining wall elements and the bottom element; on the other hand, through the engagement in positive union of the marginal zones in the grooves of the lateral elements of the wall the possibility of introducing a force of traction exerted on the front element of the wall in the lateral elements of the wall is created .
    Similarly, a rear wall element can have two grooves, in which, respectively, rear marginal areas of the front wall elements fit, when the wall elements are in the vertical position. When, as described above, the side elements of the wall are pivoted to the vertical position, the rear marginal areas of the side elements of the wall are first still free. Since the rear wall element is pivoted to the vertical position and in this case the rear marginal areas are set in the grooves of the rear wall element, the side wall elements are secured in their vertical position.
    To ensure the joint retention of the wall elements in the vertical position, in addition, holes can be formed on flanks of the grooves, in which retention projections of the marginal areas fit.
    For the torsional stability of the drawer, it is also advantageous that the grooves have steps, in which their cross-section is sharply modified and in which complementary steps of the marginal areas that fit in the grooves are supported. In this way a displacement of the marginal areas in the longitudinal direction of the grooves can be prevented or it can be reduced at least to a measure corresponding to the accuracy of fabrication of the wall elements.

    To limit the mobility of the marginal areas in the grooves in both directions, preferably each groove should have at least a first step and a second step oriented opposite the first step.
    Object of the invention is also a transport container with a support base, with a first stack of molded parts arranged on the support base, each of which comprises a bottom element and three wall elements of a drawer of the type described above in the flat position, and two stacks of front wall elements, which are adjacent to each other on two sides and in the first stack. Depending on how the elements of the wall and the bottom of the molded parts are joined together, these are configured in the top plan view in the form of T, L or Z and delimit or two corners, each of which it offers space for a first stack, or a single more spacious corner, in which two batteries can be accommodated.
    Object of the invention is also a refrigeration apparatus, in particular a domestic refrigeration apparatus, with a storage chamber and at least one drawer that can be removed outside the storage chamber, as described above.
    A drawer of this type should fill the base surface of the storage chamber, to guide the movement of the drawer and ensure good use of the space in the storage chamber.
    Other features and advantages of the invention are deduced from the following description of realization examples with reference to the attached figures.

    Figure 15 shows a section through a drawer refrigeration apparatus according to the invention.
    Figure 1 shows in perspective view a transport container according to a first aspect of the present invention. Three stacks 2, 3, 4 of molded plastic parts are formed on a transport platform 1. The molded parts of the batteries 2, 3 are identical, in which they are front elements of the wall 5 of drawers of refrigeration apparatus. The molded parts 6 of the stack 4 comprise, respectively, a bottom element 7, side elements of the wall 8 and a rear element of the wall 9 of a drawer, which are adjacent flat and are joined together by means of hinges of lamina 10. The hinges of lamina 10 extend here along side edges and a rear edge of the bottom element 7, so that the rear edges 11 not yet joined together of the side elements of the wall 10 and the lateral edges 12 of the rear wall element 9 form, respectively, a corner, in which the batteries 2 and 3, respectively, find space.
    The front elements of the wall 5 have, respectively, adjacent to their upper edge a grip recess 13, here in the form of a groove, which extends over the entire width of the wall elements 5. The depth of the recess of grip 13 should be enough for the user's fingers to find space comfortably there !; in this way a lower limit is predetermined for the thickness of the front wall elements 5. The thickness

    of the bottom elements 7 and the remaining elements of the wall 8, 9 may be smaller; here is only half the size of the front elements of the wall 5, so that the batteries 2, 3, 4 have the same height in total, although the number of the molded parts 6 in the stack 4 is twice that of the of the front elements of the wall 5 in each stack 2, 3. This contributes to the efficient use of space during transport and storage of the containers.
    The thickness of the bottom element 7 is essentially determined by the vertical displacement between a horizontal central bottom plate 14 and two skates 15 flanking the bottom plate 14. The lateral leaf hinges 10 are arranged, respectively, in the upper edge of a side wall of the skates 15, at the height of the bottom plate 14 and, in turn, at the same level as flat plates of the wall 16 of the side elements of the wall 8. The wall plates 16 are reinforced by means of surrounding ribs 17, which extend in the flat widened configuration of FIG. 1, respectively, from the plates of the wall 15 downwards and form at the rear edge 11 as well as on the leading edge 18, respectively, a profile reinforcement with an open slot up. To enable stable stacking of the molded parts 6, the width of the ribs 17 can be selected equal to the vertical displacement between the bottom plate 14 and the skates 15 of the bottom element 7.
    Correspondingly, the rear wall element 9 comprises a flat wall plate 19, which is at the same level as the bottom plate 14 and the laminated hinge 10 that connects them, and has profiles on the side edges 12 of reinforcement with essentially U-shaped cross section, which form open slots upwards.
    In a first stage of the assembly of a drawer, as shown in Figure 2, the side elements of the wall 8 are pivoted to a vertical position. In this position, the rear edges 11 of the side elements of the wall 8 are positioned in front of the grooves in the edges 12 of the rear element of the wall 9, so that, as shown in Figure 3, also the rear element from the wall 9 is folded up, the rear edges 11 fit into the grooves of the side edges 12 and are tied thereto in a manner that is explained more precisely below.

    In a final stage, the front element of the wall 5 is coupled on the front edges 18 of the side elements of the wall 8, to obtain the complete drawer 20 shown in Figure 4.
    Figure 5 shows a fragment of the front element of the wall 5. It comprises like the other elements of the wall 8, 9 a flat wall plate 21. This wall plate 21 is delimited upwards by the grip recess 13 and mentioned, not shown in figure 5, and in lateral directions by ribs 22 that distance at right angles. The ribs have on their inner sides directed towards the wall plate 21 retention projections 23 distributed along a ridge. Parallel to the ribs 22, respectively, a rib 24 that is distanced from the wall plate 21 may be provided. In parallel to the ribs 22, a rib 24 can be provided respectively, which is distanced from the wall plate 21.
    Figure 6 shows a section through the marginal areas joined together of the front element of the wall 5 and one of the side elements of the wall 8. On the leading edge 18 of the side element of the wall 8, the plate the wall 16 is reinforced by an open U profile towards the inside of the drawer. Holes 26 are distributed along a rear edge of the U-profile, such that they receive the retention projections 23 of the front wall element 5 with reduced vertical clearance.
    In the configuration shown here, only a front rib 27 of the U-profile 25 is captured between the rib 22 and the rib 24 of the front element of the immovable wall in the lateral direction to prevent it through a flexion of the lateral element of the wall 8 inside the drawer 20 (that is, downwards in the representation of figure 6), the engagement of the retention projections 23 in the holes 26 can be detached. Unlike the drawing, the rib 24 could extend in the direction from the depth still beyond the end of the rib 22 towards the rear, so that it already contacts the wall plate 16 and the side element of the wall 8 rests against an inward deflection, still before it during the coupling of the front element of the wall 5 on the lateral elements of the wall 8, the retention projections 23 have reached the holes 26.
    Figure 7 shows in perspective view a fragment of the rear area of one of the side elements of the wall 8. The rib 17, which reinforces the wall plate 16 at the rear edge 11, is extended in its edge away from the plate

    of the wall 16 in sections by means of retention projections 28 of the battlement type. When during the upward deployment of the rear wall element 9 the rib fits into the groove formed at the edge 12 of the wall element 9, designated in Figure 8 with 29, the retention projections 28 penetrate a flank of the slot 29 directed towards the wall plate 19 and in this way block the elements of the wall 8, 9.
    A variant of the joint between the elements of the wall 8, 9 is shown in Figures 9 and 10. In the element of the wall 8 shown in Figure 9, instead of the retention projections holes 31 are formed in the edge of the wall plate 19. As compensation for the weakening resulting from the union between the wall plate 16 and the rib 17, both can be joined by means of architrave plates 32. In this configuration, the projections of retention 33 are provided on the side flanks opposite each other of the groove 29, some of which fit into the holes 31, while the others surround the free edge of the rib 17. A bilateral tie of this type maintains the elements of the wall 8, 9 securely connected also when the drawer 20 is exposed to a strong torsion load, as may appear, for example, when a user lifts and transports the drawer in grab holes 34 cut into the side elements of wall 8 (see, for example, figure 4).
    Alternatively to the structure shown in figures 5 and 6, a connection could be provided, as shown in figures 8 or 10, also between the front element of the wall 5 and the side elements of the wall 8. The profile at U 25 on the leading edge 18 of the wall elements 8 it also forms a groove, in which an edge of the leading element of the wall 5 configured in accordance with the model of Figure 7 could be attached, when in This is first placed in the front edge of the bottom element 7 and then the side elements of the wall 8 extend upwards.
    When the drawer 20 is exposed to a torsion load and thus deforms, this also leads to the joined edges of the wall elements 5, 8, 9 mutually moving in a vertical direction. A displacement of this type is limited, in effect, in the configurations described with the aid of figures 5 to 10 by joints of the wall elements, because upper and lower flanks 35 of the retention projections 23, 28 or 33 collide against upper and lower edges, respectively, of the holes 26, 30 and 31, respectively, that receive them, but there! the contact surface between

    flanks 35 and the edges of the holes is small, so that overload of the material and permanent deformation or erosion of the flanks 35 can be easily produced. To solve this problem, in the configuration shown in perspective view in the figure 11 of the wall element 8, the rib 17 is divided by horizontal steps 36 into a plurality of sections 37, 38 displaced from each other in the direction of the depth of the drawer. In the configuration of Figure 11, respectively, sections 38 support the retention projections 28 in the form of teeth already shown in Figure 7, but it is evident that the corresponding retention projections could also be provided in sections 37 or retention projections could be replaced by holes 31 as shown in figure 9. The vertical section shown in figure 12 through the rib 17 and through a bottom surface 39 opposite it from the groove 29 is independent of the type of mooring between the elements of the wall 8, 9. The steps 40 on the bottom surface 39 divide the groove 29 into numerous sections with different cross-section. The steps 40, 36 that come into contact with each other of the side element of the wall 8 and of the rear element of the wall 9 make it impossible to move both with respect to each other in the longitudinal direction of the groove 29 and at the same time distribute the forces that appear in this case on a large contact surface of the steps 36, 40, so that the danger of deformation or erosion is small.
    A corresponding lock can also be established at the junction between the front element of the wall 5 and the side elements of the wall 8. In a similar way to the configuration of figures 11, 12, for this purpose some sections are lowered with respect to the others, for example, by means of steps could be formed on the inner side of the wall plate 21 between the rib 22 and the rib 24, which collaborate with complementary sections in the front edge of the side element of the wall 8. However, when the front wall element 5 is formed of transparent plastic, to make the interior of the drawer 20 visible through the wall plate 21, it may be desirable to reduce the notability of the steps 40, making them perhaps invisible , as outlined in Figure 13, on the rib 22 from the front side of the drawer 20.
    The structure shown in figure 1 of the molded part 6, with wall elements 8, 9 articulated in three edges of the bottom element 7 is only one of

    Several possibilities It is especially convenient when at height it is the smallest of the three types of drawer 20 to be made with the molded part 6. From the point of view of the best possible use of space during transport and storage, other structures may be convenient, for example , as shown in Figure 14, the rear element of the wall 9 can be connected, respectively, along three edges through laminated hinges 10 with the side elements of the wall 8 and with the bottom element 7 In the case of a reduced width of the drawer, for example, when two drawers must find space adjacent to each other in a refrigeration apparatus, a structure can also be weighted, in which the rear wall element is connected with the two lateral elements of the wall and one of the lateral elements of the wall is connected to the background element.
    Figure 15 shows a schematic section in the direction of depth through a refrigeration apparatus equipped with the drawers 20 described above, here a refrigerator 41. In a known manner itself, a body 42 and a door 43 delimit a chamber of storage 44, which is divided by tray bottoms 45 into several trays 46 superimposed vertically. While the upper trays 46 are closed, respectively, by a trapdoor 48 arranged in front, pivotable about an axis 47 that extends along its lower edge vertically between the planes, the lower trays contain, respectively, a drawer 20. As can be seen in the figure, the drawers 20 carry the bottom of the trays 46, respectively, totally except for reduced tolerances. Correspondingly, the width of the drawers 20 is also adapted transversely to the plane of intersection exactly to the width of the storage chamber 44, so that between the side walls of the body 2, the drawers 9, 10 linearly movable in the direction of depth, but without considerable play in transverse direction.
    The height of the two drawers 20 shown in Figure 15 is different; it is adapted, respectively, to the height of the trays 46 that receive the drawers 20, so that a stop projections 49 formed in the upper edge of the lateral element of the wall 8 collide during the extraction in complementary stop projections 50 in the bottom side of the bottoms of the trays 46. In the stop position defined in this way, the grip holes 34 are accessible, so that the drawer can be set in these grip holes 34, it can be
    Pivot slightly to cancel the stop and then it can be removed outside the storage chamber.
