Description

Refrigerating appliance with an extracted refrigerated goods container

The present invention relates to a refrigeration device, in which a refrigerated goods container such as a vegetable drawer on pull-outs out of the interior of the refrigerator is pulled out. The extracts generally comprise a plurality of intermeshing rails, one of which is attached to the refrigerated goods container and another to the housing of the refrigerator. In most cases, the rails with the help of rollers or balls arranged between them are made easily and friction against each other, so that a refrigerated goods carried on such extracts can be pulled out and re-inserted with little effort even in fully loaded condition.

To ensure good mobility of the rails, the extracts carrying a refrigerated goods must be mounted exactly parallel to each other, usually on the side walls of the body of such a refrigerator.

In less costly equipped refrigerators is a pull-out refrigerated goods in a lower compartment of the interior simply on the bottom of the compartment and grinds when pulling out of this. The friction that occurs when pulling out such a refrigerated goods container is generally distributed unevenly over the bottom surface of the pull-out container, and it can also vary in the course of movement of the container, so that the risk is very great that in a careless pulling on the container this in the Tray slants and wedged between the side walls of the compartment. The risk that this happens, the greater, the greater the ratio of the width to the depth of the refrigerated goods is. It has therefore already been proposed in refrigerators with a wide interior, to arrange two refrigerated goods next to each other in such a subject. This gives each of these refrigerated goods a better ratio of width to depth and can be handled without significant risk of wedging.

In order to improve the ease of use of such a refrigeration appliance, it would be desirable to be able to perform two refrigerated goods containers arranged side by side in a compartment by means of pull-outs with low friction. However, it is necessary to extract extracts for guiding the two refrigerated goods containers to be accommodated in an intermediate space between the two and to hold them permanently exactly parallel to pull-outs acting on the outsides of the two refrigerated goods containers.

A support of these extracts at the bottom of the inner container is only considered if the refrigerated goods occupy the lowest compartment of the interior.

Object of the present invention is to provide a refrigeration device, in which two refrigerated goods next to each other spaced from a bottom of the interior are mounted easily movable.

The object is achieved by a refrigeration device with a thermally insulated housing, which surrounds an interior, in which two refrigerated goods next to each other by a bottom of the interior space and pulled out, in which the refrigerated goods are guided by extracts, with a extending between the refrigerated goods longitudinal beams , is mounted on the respective one of the extracts of each refrigerated goods, is supported via at least one cross member on side walls of the housing.

According to a first aspect, an end of the side member adjacent to a rear wall of the housing is fixed to the rear wall, and the cross member engages the side member adjacent to a front end thereof. Thus, the side member is supported at both ends both in the vertical and secured against sideways movement, which could affect the parallelism of the extracts and could lead to a sticking of the refrigerated goods carried by them.

Preferably, the longitudinal member is attached to the rear wall by means of tabs, which are angled from the rear wall of the adjacent end of the longitudinal member in opposite directions.

Alternatively, the side rail could also be supported on the side walls of the housing via two cross members, which act on opposite ends of the side member. In order to absorb manufacturing tolerances in the dimensions of the inner space, one of the two ends of each cross member is preferably located loosely on each of a bearing surface of the side wall. Transverse to the longitudinal direction of the cross member, the one end should be positively fixed to the support surface to prevent lateral slipping.

Preferably, the cross member extends below the refrigerated goods; but it is also conceivable to let it run above the refrigerated goods and depend on the side member of him.

If the cross member extends below the refrigerated goods, it can advantageously serve simultaneously as a support for an edge of a cover plate of a lying below the refrigerated goods compartment.

If the refrigerated goods only partially fill the depth of the interior, the cover plate preferably extends between the cross member and a front of the interior, that is, in front of the refrigerated goods when they are in an inserted position; and the cover plate is transparent to allow the view from above into the compartment below the refrigerated goods container.

A cover plate may also be provided between the cross member and the rear wall of the interior. If this is the case, the longitudinal member should be detachable from the cross member to remove and remove the cover plate after removal of the longitudinal member.

Alternatively, the cover plate can be subdivided along the longitudinal carrier, so that its two parts can be removed in each case without the longitudinal carrier having to be removed for this purpose. Conveniently, the two parts of the cover plate can then rest on the side member for support.

The two refrigerated goods containers arranged next to one another in a two-door refrigeration appliance are particularly advantageous if each of the refrigerated goods containers is aligned with one of the doors, so that it can be pulled out if only one of the two doors is opened. - A -

For better traceability, the refrigerator according to the invention is explained with reference to a sequence of figures showing it in different stages of its interior decoration, the order in which the individual components are explained and appear in the figures, although a possible, but not necessarily the only possible sequence of their assembly corresponds.

As an example of a refrigerator according to the invention, FIG. 1 shows a combination appliance whose body 1 surrounds a cooling space 2 in an upper area and a freezer space in the lower area. The freezer compartment is closed by a door panel 3, which is not hinged to the body 1, but is attached directly to an extracted in the freezer drawer and is pulled forward in parallel to pull out the drawer from the freezer and access its contents.

The refrigerator 2 is closed by two doors 4, 5, which are hinged to side walls 6, 7 of the body. On the inside of the side wall 7, a telescopic extension 8 can be seen; a corresponding telescopic extension is mounted mirror-symmetrically on the inside of the opposite side wall 6. The structure of the telescopic extension 8 will be explained in more detail later with reference to FIG. 2.

A lowermost compartment of the cooling chamber 2 is bounded at the top by a cross member 9, which is held on the side walls 6, 7 in each case with the aid of a mounted approximately below the front edge of the telescopic extension 8 mounting bracket 10. The cross member 10 is provided approximately centrally with two holes 12. Cross member 9 and mounting bracket 10 will be explained later with reference to FIG. 3 in more detail.

An elongated Auflagesims 11 extends along the rear wall of the body 1. In the compartment below the cross member 9 and the support ledge 11 is a over the entire width of the cooling chamber 2 extending drawer 45 on (not shown) guided telescoping rails added.

A (not shown) evaporator is housed in a chamber under the ceiling of the body 1 and communicates with the refrigerator compartment 2 and the freezer compartment via not visible in the figure air intake and exhaust ports. A channel 13, over the cold air from the evaporator chamber to the freezer compartment, extends inside the rear wall of the carcass; its course on the finished device not recognizable course is shown by dashed lines.

On both sides of the channel 13 blind holes 14 are formed in the rear wall, which are provided for receiving and holding a screw or a bayonet pin.

Fig. 2 shows in detail the telescopic extension 8 of Fig. 1. The telescopic extension 8 is composed of two identical pairs of interlocking rails 15, 16 and 16, 17, wherein the back-to-back contacting rails 16, 17 of the two pairs together riveted or permanently fixed in other ways. Angled from the rail back legs each have a curved course with facing concave sides to form cylindrical channels 19. In each case in the figure, not visible balls are added, which guide the rails 15 and 16 or 17 and 18 with minimal play and friction against each other.

The rails 16, 18 each carry one of the other rail 15 and 17 of the pair facing bolt 20 which touches in the figure shown fully inserted stop position of the telescopic extension 8 a fixed to the rail 15 and 17 rubber buffer 21 In the figure not visible, attached to the rear ends of the rails 16, 18 bolts 20 limit by striking the rubber buffers 21, the freedom of movement of the rails against each other in the fully extended state.

Plastic adapters 22, 23 are latched to holes punched in the back of the rail 18. The angle-shaped adapters 22, 23 each carry on a horizontally over the upper legs of the rails 16, 18 extending portion a locking head 24, 25, which serves to anchor a refrigerated goods, not shown in the figure to the adapters 22, 23.

The telescopic extensions which carry the drawer 45 have a similar construction to that shown in FIG. 2, but each comprise only a pair of rails. While the use of two pairs of rails in the telescopic extension 8 gives this a freedom of movement which is greater than the length of the rails, this is in the Telescopic extensions of the drawer 45 not the case. Since the latter telescopic extensions but as the drawer 45 extend over virtually the entire depth of the cooling chamber 2, the freedom of movement achieved with them enough to draw the drawer 45 from the position shown in FIG. 1 so far that it protrudes completely below the cross member 9 so that their content can be accessed conveniently.

Fig. 3 shows a portion of the cross member 9 and serving for its attachment to the side wall 6 and 7 mounting bracket 10. The cross member 9 is an extruded or preferably roll-formed steel profile with a central portion 27 and on both sides of this central portion 27 through a step stepped narrow webs 28. The middle portion 27 is hollow, so that a first tab 29 of the mounting bracket is inserted into the cavity.

A second tab 30 of the mounting bracket 10, here shown with two bores, is provided to be bolted to the side wall 6 or 7 of the body. While at one end of the cross member 9, the inserted tab 29 of the mounting bracket 10 is pressed, soldered, screwed or fixed in any other way, the tab 29 of the local mounting bracket 10 is left movable at the opposite end. Thus, 9 different manufacturing tolerances in the width of the cooling chamber 2 can be compensated by differently far insertion of this tab 29 in the cavity of the cross member.

Fig. 4 shows a longitudinal member 31, which is provided to be attached on the one hand to the cross member 9 and on the other hand to the rear wall of the body 1. The one-piece formed from a blank of sheet steel longitudinal member 31 has a main body 32 in the form of a narrow, downwardly open U-profile, are angled at the front end of two horizontal fastening tabs 33 and from the rear end two large vertical tabs 34 are angled, are each provided with holes 35 which are aligned in the installed position of the longitudinal member 31 with the bores 12 of the cross member 9 and the blind holes 14 on the body rear wall to accommodate mounting screws or bayonet pins. On the two legs of the U-profile of the main body 32, a telescopic extension 8 of the type shown in Fig. 2 is mounted in each case. Fig. 5 shows the refrigerator of Fig. 1 in a more advanced state of development. Between the cross member 9 and the rear wall of the body 1, resting on the rear web 28 of the cross member 9 and on the ledge 11, a glass plate 37 is placed, which separates the drawer 45 from the overlying portion of the cooling space 2. Bridging the glass plate 37, the longitudinal member 31 is attached to the rear wall of the body 1 and to the cross member 9. Fixing can be done by means of screws or, for the sake of easy and quick disassembly by the user, by means of bayonet pins. The telescopic extensions 8 of the longitudinal member 31 are those of the side walls 6, 7 in parallel and opposite to the same height.

At this stage refrigerated goods container 38 can be latched to the telescopic extensions 8, as shown in Fig. 6. The refrigerated goods containers 38 are, like the underlying drawer 45, boxes which are open at the top and are made of a transparent plastic. The width of the refrigerated goods container 38 is adapted to the doors 4, 5, that in each case one of the refrigerated goods from the refrigerator 2 is pulled out when only the front door 4 or 5 is open in each case.

Another glass 39 is now on the front web 28 of the cross member 9 and on projections 40 on the side walls 6, 7, so that the lower drawer is completely covered.

Even if the freedom of movement of the telescopic extension of the lower drawer 45 is not sufficient to pull them completely under the glass 39, access to refrigerated goods in the rear of this drawer 45 without difficulty, since the glass sheet 39 can be swung up at its front edge.

Finally, in FIG. 7, the refrigerated goods containers 38 are also covered by a glass pane 41.

An alternative embodiment of the longitudinal member 31 and the cross member 9 is shown in Fig. 8. The horizontal fastening tabs 33 are omitted here, instead of the lower edges of the two main body 32 forming U-profile legs each one

Locking projection 42 arranged so that, when the vertical fastening tabs 34 on the rear wall of the cooling chamber 2 are fixed, abuts a shoulder facing away from the viewer between the central portion 27 and the rear web 28 of the cross member 9.

A plastic block 43 is inserted from the front between the legs of the U-profile and prevents them from being forced against each other by a pressure acting from the lateral direction.

The cross member 9 carries two projections 44, whose distance from one another exactly corresponds to the thickness of the main body 32, so that it can be inserted from above without play in the space between the projections 44. If under the weight of refrigerated goods container 38 and its content of the cross member 9 bends slightly, the projections 44 tilt towards each other and clamp the side member 31, the harder the load is. Thus, the longitudinal member 31 is exactly fixed to the cross member 9, without the need for additional fasteners would be required for a disassembly of the longitudinal member 31 would need to be solved time-consuming again. It is sufficient that the pull-out boxes are removed so that then again unloaded cross member 9 releases the longitudinal member 31, so that the latter can also be removed and finally the glass plate 37 can be removed to clean them.

In the variant shown in Fig. 9, the vertical tabs 34 on the side member 31 are omitted, and instead there are provided two cross members 9 of the type shown in Figure 8 for clamping the side member 31 at its front and rear ends.

The position of the longitudinal member 31 in the depth direction of the body 1 is defined by a latching projection 42 at its lower edge, which extends here between opposite shoulders of the two cross members 9. This longitudinal member 31 is fixed completely automatically without the use of additional fasteners, alone

Load on the cross member 9.

It is noteworthy in the variant of FIG. 9 a from the lower edge of the locking projection 42 horizontally to the side angled web 51, the top, when the longitudinal beam 31 is placed on the cross member 9, to lie in the same height as the tops of their webs 28 comes. The web 51 forms here together with the webs 28 a support surface for a glass plate 52. This replaces together with a not shown in the figure, corresponding glass plate on the opposite side of the Longitudinal support 31, the glass plate 37 of FIG. 5. In order to remove the glass plates 52, it is therefore no longer necessary to previously remove the longitudinal beam 31. It is obvious that such a division of the glass plate 37 and optionally the two parts supporting webs 51 can also be provided on a longitudinal member 31 of the type shown in Fig. 4 or Fig. 8.
