Abstract

The carrier has a plastic body, and an adjusting surface e.g. glass plate (1) and wire grid, extending between two lateral edges and between front and rear edges. One of the lateral edges has downwardly opening rear and front recesses (8a, 8b) adjacent to the front and rear edges, respectively. The recesses have undercuts (17) at a front side that is turned towards one of the edges. The front recess has an inclined surface (16) formed towards the front side, and the undercuts have another inclined surface (19) parallel to the former inclined surface.

Description

The present invention relates to a refrigerated goods for a refrigeration appliance, in particular a household refrigerator. Such a refrigerated goods carrier generally has a shelf in the form of a glass plate or a wire mesh, optionally surrounded by a frame, and is mounted in a storage chamber of a refrigerator by its lateral wheels are inserted into horizontal grooves extending on side walls of the storage chamber.

The inner containers of refrigerators are generally made by deep drawing. This technique implies that the opposing side walls of the storage chamber are not exactly parallel, but slightly diverge toward a front of the device. The shape of the refrigerated goods carriers must take account of this non-parallelism, the so-called draft angle.

More recently, refrigerators have come on the market, in which instead of grooves which receive the edges of the refrigerated goods carriers, carrier cams are provided which project from the side walls into a storage chamber of the refrigerator in order to support a refrigerated goods. To compensate for the draft angle, a cam adjacent a front edge of the sidewall may protrude somewhat further into the interior of the bearing chamber than a cam located near the back wall.

A problem with the use of the cams results from the fact that they, unlike the grooves, support a refrigerated goods only at specific points. If the support points are close to a front or rear edge of the refrigerated goods carrier, then a slight displacement is sufficient to allow the refrigerated goods carrier to slide off the cam and cause it to crash. On the other hand, if the cams are arranged rather centrally, there is a risk that a refrigerated goods carrier will tip over by objects which are on an unsupported front or rear edge area.

Object of the present invention is to provide a designed for supporting on cam refrigerated goods, which is both safe against slipping and insensitive to overloading of a peripheral region.

The object is achieved by having at least one of the lateral flanks at least two downwardly and outwardly open facing away from the footprint recesses in a refrigerated goods with a between two lateral flanks and between a front and a rear edge extending footprint, of which at least one first recess has an undercut on a first end face facing one of the edges. These recesses can, for example, at least partially receive such a positively protruding from the refrigerator side wall of a household refrigeration appliance carrier, in particular carrier cam that a vertical movement of the refrigerated goods is prevented by the engagement of the carrier in the recess. By a cam engages in this undercut, he can not only take the weight of the refrigerated goods, but also prevent it from swinging up when the refrigerated goods is overloaded in an edge region beyond the second recess.

Preferably, the recess of the first end face on a second end face of the recess opposite an inclined surface. By touching the chamfered surface when placing the chilled goods carrier on the cam, the cam is guided into the undercut, without it requiring the special attention of the user, and thereby secured.

A parallel to the inclined surface of the second end face inclined surface of the undercut allows a low-backlash guidance of the refrigerated goods carrier to its final position.

Preferably, the first recess adjacent to the front edge and the second recess to the rear edge of the footprint. This facilitates the placement of the refrigerated goods carrier, since it is sufficient for placing the cam in the undercut to push the refrigerated goods in the direction of a rear wall of the storage compartment or to let him, guided by the inclined surface on the second end face, easy to slide on this back wall.

It also contributes to simplifying the placement of the refrigerated goods carrier when the second recess is open at a side remote from the first recess side.

The refrigerated goods carrier preferably comprises a carrier plate and strips attached to lateral edges of the carrier plate, in which the recesses are formed. This allows a simple production of the carrier plate, in particular in the form of a rectangular glass sheet.

The strips, however, can be made of a - preferably metallic - hollow profile. In such a hollow profile, the recesses may be formed in particular by milling.

A plastic body, which preferably at least partially fills the hollow profile, can serve for various purposes. In particular, the plastic body may be shaped so that it engages beyond edges of the hollow profile in the recesses and thus prevents direct contact of the possibly sharp-edged edges of the hollow profile with the cooling goods carrier supporting cam.

In addition, the plastic body can serve for anchoring a railing, which extends at one of the edges of the footprint. Preferably, it extends to a rear edge of the footprint to prevent chilled goods placed on the footprint from contacting and freezing or moistening a rear wall of the storage chamber.

The railing can be designed as a wire bracket with each engaging in the plastic body of both strips ends; Such a wire hanger can simultaneously serve as a handle which facilitates the handling of the refrigerated goods carrier outside the storage chamber.

In order to give the railing firm hold in the plastic body, an engaging in the plastic body anchoring pin, which forms one end of the railing, expediently provided with a grain.

In order to give the plastic body firm hold in the hollow profile, an elastically pivotable latching projection is expediently formed on the plastic body, which engages in a latching recess of the hollow profile.

This latching recess is preferably formed in a surface of the hollow profile, which faces one of the downwardly and outwardly open recesses. Thus, with the aid of a tool that is inserted through the recess, the locking recess can be realized so that it is not visible on the finished assembled strip from the outside.

It is particularly expedient to form the latching recess in a wall of the hollow profile which separates an edge of the carrier plate receiving groove of one of the downwardly and outwardly open recesses. Here, the locking recess is not visible from the outside even if it completely pierces the wall.

The invention also provides a refrigeration device with projecting from the side walls of a storage chamber in the storage chamber, engaging in the recesses of a refrigerated goods carrier of the type described above carrier cam.

The depth of the undercut of a first of these recesses should here be greater than the play in the depth direction of the bearing chamber with which a second of the cam engages in a second recess to ensure that despite the play of the second cam in this second recess of the first Carrier cam can not move out of the first undercut by a simple horizontal displacement of the refrigerated goods carrier.

The cams are preferably attached to the side walls of the refrigerator moldings. In this case, the back wall near and close to the door cams may differ in their length to compensate for the draft angle of the side walls; but it is also conceivable that the cams are all identical and the Entformungsschräge is compensated by the dimensions of the recesses in the width direction of the housing so that the game of Kühlgutträgers in the width direction between the front cam is substantially the same as between the rear cam.

In order to ensure a secure and accurate guidance of the refrigerated goods carrier, the cams expediently to the inclined surfaces of the recesses parallel oblique facets.

The distance between mutually parallel oblique facets of a cam preferably corresponds to the distance between mutually parallel inclined surfaces of a recess, so that the refrigerated goods in the fully assembled state is kept substantially free of play.

Fig. 1 shows a perspective view of a refrigerated goods according to the invention for installation in a storage chamber of a (not shown) household refrigerating appliance. The refrigerated goods carrier comprises a horizontal rectangular glass plate 1 in the installed position, which alternatively could also be replaced by a plate made of another material, a grid or the like. On in the depth direction of the refrigerated goods receiving Refrigeration device housing extending side edges 2 of the glass plate 1, two strips 3 are mounted, each comprising an extruded profile 4 made of aluminum and a plastic body 5 received in a cavity of the extruded profile 4. The extruded profiles 4 have a cross section similar to the letter "a", with a hollow lower portion 6, in the cavity of the plastic body 5 is inserted, and a hook-shaped over the lower portion 6 extending and with this one of the side edges 2 of the glass plate 1 receiving Groove limiting upper portion 7. At one facing away from the glass plate 2 outer edge of the lower portion 5 of each bar 3 downwardly open recesses 8 are formed, which are each provided to receive one attached to a side wall of the refrigerated goods receiving storage chamber carrier cam 9. This in Fig. 1 not shown carrier cam 9 will be described later with reference to Fig. 2 described in more detail.

The plastic body 5 extend in the interior of the strips 3 to the rear end, where they each receive an end of a wire bracket 10. A central portion of this wire bracket 10 extends along the rear edge of the glass plate 1 above this, thus forming a railing that prevents refrigerated goods placed on the glass plate 1 is pushed up to the rear wall of the storage chamber and freezes at this. The distance in which the wire bracket 10 extends above the glass plate 1 is large enough for a user to grasp the wire bracket 10 with his fingers and use it as a handle for handling the refrigerated goods carrier outside the refrigerator.

At two mutually facing vertical edges of the lower portions 6 of the extruded profiles 4 two mutually paired opposite openings are formed, in which adapters 11 are locked in plastic. The two mounted on a same extruded profile 4 adapter 11 are equal to each other and mirror images of corresponding adapters 11 on each other extruded profile 4. Each two adapters 11 hold together like the railing of a rigid wire integrally molded bottle carrier bracket 12. In Fig. 1 invisible, outwardly angled journals of the bottle carrier bracket 12 engage in bearings of the adapter 11 a. By elastically bending the bracket 12, it is possible to extract these journals from their camp and so solve the bottle carrier bracket 12 from refrigerated goods to store them outside the refrigerator or to another refrigerated goods with identical attached trained strips 3, which is mounted in the storage chamber on a different level.

In order to enable a displacement of the bottle carrier bracket 12 between different refrigerated goods carriers, all or at least more of the refrigerated goods carriers mounted in the storage chamber of a refrigerator according to the invention are expediently provided with the adapters 11. In a refrigerated goods, which is not provided to mount the bottle carrier bracket 12 thereto, the adapter 11 or even provided for locking the adapter 11 openings may be missing in the extruded profiles 4 of the refrigerated goods.

Fig. 2 shows in a perspective view of a support cam 9, of which four are each provided to be mounted on opposite side walls of a storage chamber of the refrigerator in pairs opposite to each other and the in Fig. 1 to support refrigerated goods shown. The carrier cam 9 each comprises a flat plate 13, which bears against the wall of the storage chamber, a in Fig. 2 non-visible projection which engages in a complementary shaped recess of the side wall of the refrigerator, and a pin 14 which is provided to engage in one of the recesses 8 of the refrigerated goods carrier. The pin 14 is octagonal in cross-section, with oblique facets 15, 18 at the top and bottom. The carrier cam 9 is mirror-symmetrical with respect to a vertical plane, so that a same type of carrier cam 9 can be mounted on the right and left side walls of the storage chamber.

Fig. 3 shows a side view of the refrigerated goods, at which the relative movement of one of the strips 3 and the pin 14 is illustrated during assembly of the refrigerated goods in the refrigerator. A rear recess, denoted by 8a, is open to the rear, the front, denoted by 8b, is significantly wider than the pin 14 which it is intended to receive. This makes it easy, when placing the refrigerated goods carrier to bring the pins 14 for engagement in the recesses 8a, 8b.

After engagement, one of the oblique facets 15 at the top of the carrier cam 9 comes into contact with an obliquely upward and forward (to the right in the perspective of Fig. 3 ) extending inclined surface 16 of the front recess 8b. Of the Contact between the facet 15 and the inclined surface 16 drives the refrigerated goods carrier to the rear (or to the left in the Fig. 3 ), whereby both pins 14 engage in undercuts 17 at the front end sides of the recesses 8a, 8b. In this case, a parallel to the facet facet 18 18 at the bottom of each pin 14 in contact with an oblique lower edge 19 of the undercut 17. The inclined surface 16 and the oblique lower edge 19 of the recess 8b lead the front pin 14 substantially free of play. In the end position of the refrigerated goods carrier, in each of which a horizontal underside of the recesses 8a, 8b rests on horizontal upper sides of the pins 14, the refrigerated goods carrier is stable and substantially free of play in the depth direction. The pins 14 can therefore not disengage from the undercuts 17 without a simultaneous increase in the refrigerated goods carrier. An overload of a front or rear edge region of the glass plate 1, in front of and behind the front / rear support cam 9, can not lead to a tilting of the refrigerated goods carrier, since the engagement of the pins 14 in both undercuts 17 and in particular the contact of the facet 18 with the lower edge 19 of the undercuts 17 prevents this. A removal of the refrigerated goods by a user, however, is not difficult, since the predetermined by the shape of the recesses 8 removal movement of the tendency of a user to raise and to prefer to pick up a refrigerated goods simultaneously comes.

Fig. 4 shows in a perspective view the already mentioned plastic body 5, which fills a cavity in the lower portion 6 of the extruded profile 4. At the viewer facing longitudinal edge of the plastic body 5, the two recesses 8a, 8b can be seen; on an opposite flank there are two recesses 20, which leave space in the cavity of the extruded profile for snap hooks of the adapter 11. A further recess 21 is formed on the upper edge of the viewer facing flank above the inclined surface 16. In this recess 21 engages in the longitudinal direction of the plastic body 5 extending elastic tongue 22 a. A latching projection 23 at the free end of the tongue 22 is provided to, as in the cross section of Fig. 5 shown in a bore 30 of the extruded profile 4 to lock the plastic body 5 and so to fix the plastic body 5 in the extruded profile 4. The bore 30 is driven from below through the opening of the recess 8 b in the upper portion 7 of the profile 4 in and therefore no longer visible from the outside as soon as the plastic body 5 is inserted into the extruded profile 4.

From the cross section of Fig. 5 Furthermore, it is clear that the edges 8b delimiting edges 24, 25 of the extruded profile 4 spring back slightly behind corresponding surfaces 26, 27 of the plastic body 5, so that the weight of the refrigerated goods carrier is not introduced from the edge 24, but via the surface 26 into the carrier cam 9 becomes. Thus, the carrier cam 9 is largely protected from scratching and impact marks.

Fig. 6 shows in a greatly enlarged perspective view of an anchoring pin 28 at a free end of the wire bracket 10. The anchoring pin 28 is provided adjacent to its tip with a plurality of grains 29, that is, by hitting or pressing with a pointed tool are depressions in the peripheral surface of the anchoring pin 28th pressed, and the displaced material forms a crater-like ring around the depression. By the plastic body 5 is molded onto the anchoring pin 28 and thereby surrounds the grits 29 positively, a secure anchoring of the wire bracket 10 is ensured on the strips 3, which allows to use the wire bracket 10 as a handle for handling the entire refrigerated goods carrier as needed ,
