EP2010845B1 - Shelf bottom for a refrigerator - Google Patents

Description

The present invention relates to a shelf for a refrigeration device.

Conventionally, such shelves are often realized in the form of a support plate to which a peripheral frame is formed, on which contours, projections, etc. are formed, which are needed for suspension of the shelf in the interior of the refrigerator.

This technique is costly because it requires a separate mold for frame production for each model of shelf.

DE 94 20 293 U1 discloses a shelf support for store shelves having an extruded profile having at least one chamber for receiving an adapter and at least one leg for laying a shelf, wherein the leg is arranged asymmetrically with respect to the chamber, so that the extruded profile on the adapter in two with respect to each other turned positions can be attached, in which the leg occupies different altitudes.

EP 1 431 688 A1 discloses a shelf for a refrigeration appliance, in particular bottle shelf for a bottle storage refrigerator, comprising a frame formed by transverse and longitudinal struts and a shelf, wherein at least one of the transverse bars on at least a portion of its cross section through an extruded profile of a material having a higher modulus of elasticity than that of the material the longitudinal struts is formed.

US 3,633,983 discloses a cabinet structure including a slide member framing a glass bottom, parallel spaced sides or runners, and a connecting rear face all made of identically extruded material such as metal or plastic. The multiple sides can be formed from a single extrusion and bent in a U-shape using known techniques, or assembled from separate, suitably bonded lengths of extruded stock.

US 5,332,611 discloses shelf edge panels with a one-piece integral A structure for providing a U-shaped body portion for releasably receiving and supporting a shelf of a refrigerator. The shelf edge trim panels are formed of extruded plastic strips, with the shelf edge trim panels comprising a decorative front lip portion for a front edge of the shelf or a rearwardly and upwardly extending flange portion for a trailing edge of the shelf to provide a shelf shelf rear stop. The shelf edging panels are pushed onto round bars of the frame of the shelf. The frame is made up of round rods and side plates.

Also known are shelves that have a glass plate as the support plate, wherein on the front and rear edges of the glass plate, a profile part is attached, the ends of the profile parts are extended beyond the side edges of the glass plate out and supported in grooves of the side walls of the refrigerator. Since the carrier plate is not completely enclosed in this known shelf, there is a possibility that it dissolves out of the groove of a profile part and then crashes. In addition, this construction leads to the fact that the attached profile parts must carry a high weight on a small cross section, so that the capacity of the shelves is limited.

The object of the invention is to provide a shelf for a refrigeration device, which is resilient and safe, and which is inexpensive to implement in a variety of variants.

The object is achieved by a shelf for a refrigerator with a frame enclosed in a frame support plate, in which the frame of Extrusionsprofilstücken and ends of Extrusionsprofilstück connecting profile parts is joined together, wherein the profile parts each have the shape of an elongated beam, which at its ends in two widened or raised head pieces passes. The encircling frame gives the shelf a secure cohesion without the risk that the carrier plate and profile pieces separate from each other. The use of the extrusion profile pieces makes it possible to inexpensively realize shelf models differing only in one dimension, by adding to the edges of the carrier plate whose dimensions vary from model to model, extrusion profile pieces made of strand material with different ones as required

Lengths can be cut, and the profile parts are added to the edges with the same length, so that uniform profile parts can be used for all models. Furthermore, this design provides the ability to use uniform support plates for shelves with different appearance, which receive a specific for different model series or brands of the same manufacturer character by using different types of profile parts and Extrusionsprofilstücken.

The profile parts, which are needed in a smaller number of variants, can be injection molded.

In order to ensure the cohesion of the frame, the profile parts preferably carry pins which engage in cavities of the extrusion profile pieces.

It can only have the extrusion profile pieces or only the profile parts or both a groove into which engages a wall of the support plate.

The support plate may in particular be a glass plate, or else a grid with a peripheral frame and two struts connecting to opposite sides of the frame. In such a grid, the ends of the struts are preferably connected frontally to the frame.

To store bottles, especially wine bottles, stable on such a grid shelf, the distance between adjacent struts is at least equal to half the diameter of a wine bottle and smaller than the entire diameter of a wine bottle.

Furthermore, the length of the struts tentatively at least twice the length of the belly of a wine bottle, so that they can be stored in alternating orientation, each with a bottleneck between two bellies, tight and accordingly with good space utilization on the shelf.

In order to make the shelf easily pulled out, it is preferably carried by telescopic extensions. For this purpose, the extrusion profile pieces preferably in Cross-section of a vertical and a horizontal leg, and a telescopic extension is hidden in a spanned by the two legs angle of each extrusion profile piece added.

For attachment to the telescopic extension preferably one of the legs on a cavity with longitudinal side, the telescopic extension facing openings are latched into the locking heads of the telescopic extension.

As in Fig. 1 and 2 The shelf according to the invention is essentially composed of five parts, a carrier plate 1, front and rear profile parts 2, 3 and lateral extrusion profile pieces 4, 5. The carrier plate 1 is here as a grid with a frame of a strong steel wire integrally bent frame. 6 and a plurality of longitudinal struts 7 extending between front and rear cross braces 8 of the frame 6. The longitudinal struts 7 are made of wire from same type as the frame 6. They lie with the frame 6 at the same height, so that they are each welded to their end faces on the cross braces 8.

The frame 6 is held laterally in grooves 9 of the extrusion profile pieces 4 and 5, respectively. The extrusion profile pieces 4, 5 have identical cross sections similar to the letter r, with a vertical leg 10, in which the groove 9 is formed, and a subsequent to the upper end of the leg 10 horizontal leg 11. One of the two legs 10, 11 spanned Angle is provided to accommodate a telescopic extension 12 which is in Fig. 3 is shown in more detail. The extrusion profile pieces 4, 5 have, as in particular in Fig. 4 each having three cavities, a cavity 13 in the horizontal leg 11 and two 14, 15 in the vertical leg 10 above or below the groove 9. In the lower wall of the cavity 13 at least two openings 16 are cut, one of which in the sectional view of Fig. 4 you can see. The rear of the two openings is open towards the rear end of the extrusion profile piece 4 and 5, respectively.

The openings 16 are used for locking the extrusion profile pieces 4, 5 on the telescopic extensions 12, one of which in Fig. 3 is shown in perspective view. The drawer 12 comprises two rails bent from sheet steel, an outer rail 18 of approximately C-shaped cross-section, and an inner rail 19 engaging the cavity of the outer rail 18 and intended to be fastened to the side wall of a refrigerator housing. Opposite horizontal legs of the rails 18, 19 define two cylindrical channels 20, in which, as in Fig. 4 to see balls 21 are added, which guide the rails 18, 19 with little play and easily against each other. A bolt 22 projects from the front end of the outer rail 18 into the space between the rails 18, 19. Its contact with a fastened to the inner rail 19, in Fig. 3 just visible rubber buffer 23 defines a limit to the freedom of movement of the rails 18, 19 against each other.

A front adapter 24 and a rear plastic adapter 25 are attached to the outer rail 18. The adapters 24, 25 each have an approximately prism-shaped base body 26, to which a horizontal web 27 resting on the upper leg of the rail 18 is integrally formed on its upper side.

From the top of the main body 26 is respectively a locking element 28 and 29 from which is provided to engage in the openings 16 of the extrusion profile piece 4.

When mounting the support plate 1 on the attached to side walls of the refrigerator telescopic extensions 17, the rear edge of the support plate 1 is placed on the telescopic extensions 17 and moved backwards until the rear locking elements 29 engage in the rear, open-edged openings 16 of the extrusion profile pieces 4 and 5 and an edge of the rear opening 16 of each extrusion profile piece 4, 5 in an undercut 30 at the front of the locking element 29 of each telescopic extension 12 engages. Now, when the support plate 1 is pivoted in the horizontal, engage the front locking elements 28 in the front openings 16 of the extrusion profile pieces 4, 5 a. The front detent element 28 has approximately the shape of a T, with slightly pulled outwardly from the ends of the crossbar of the T, slightly outwardly bulging elastic legs 31. The legs 31 are pressed against each other when passing through the front opening 16 elastically, and the downwards converging lower ends of the legs 31 hold the extrusion profile pieces 4, 5 in the depth direction backlash and press them from above against the base 26th

As in the Fig. 2 and 5 To recognize, the front and rear profile parts 2, 3 each have the shape of an elongated beam, which merges at its ends into two widened or raised head pieces 33. The head pieces 33 each carry a plurality of hollow pins 34, 35, 36, which are provided to positively and frictionally engage in the cavities 13, 14, 15 of the extrusion profile pieces 4, 5 from the open ends thereof. Between the pins 35, 36 is one end of a over the entire length of the beam 32 extending groove, which is part of the already mentioned, the frame 6 enclosing groove 9 and therefore in the FIGS. 5 and 6 also designated 9.

Fig. 7 shows a perspective view of the shelf Fig. 1 loaded with lying bottles of wine 37 state. The bellies 38 of the bottles are each supported by two adjacent longitudinal struts 8. The distance between two adjacent longitudinal struts 8 is significantly smaller than the diameter of the cylinder bell 38, but greater than the average diameter of the cylinder belly 38 and neck 39. So For example, the bottles 37 can be inserted in an alternating orientation between each two adjacent longitudinal struts 8, wherein the neck 39 of a bottle 37 fits between the bellies 38 of two adjacent bottles 37.
