Abstract

The refrigerator has a carrier (6) movably supported on telescopic rails (9) in a cooling space and including plates (7) e.g. glass plates, laterally enclosed by two frame profiles (8) e.g. aluminum extrusion profiles. A recess (14) is formed in the profiles and extensively receives one of the telescopic rails in a moved position. The profiles are connected to the recess. Guard rails (16, 17) are extended to front and/or rear edge of the plates. The profiles have an extruded longitudinal channel (15) that is attached to ends of the guard rails. Plastic strips are attached to the profiles.

Description

The present invention relates to a refrigeration device, in particular a household refrigeration appliance, in which a refrigerated goods carrier is held displaceably on telescopic extensions. Such a refrigeration device is off, for example DE 10 2006 061 096 A1 known.

In this known refrigeration device, the telescopic extension comprises at least one pair of rails and a clamping profile clamped onto a rail of the pair, which covers a lateral flank of the rail and reaches under the rail in order to catch any sloping dirt particles. Two adapters, which serve to anchor an extension box, protrude over the profile. In use, the profile is essentially hidden by the drawer so that neither itself nor the adapters are visible.

In a plate-shaped refrigerated goods, it is not readily possible to hide the telescopic rails and the adapter that connect the refrigerated goods with the telescopic extension. This is particularly troublesome when the plate of the refrigerated goods carrier is a transparent glass plate. There is therefore a need for a refrigeration device that allows in a simple way to hide telescopic extensions of a plate-like refrigerated goods carrier.

The object is achieved by comprising in a refrigerator, in particular a household refrigeration appliance, with a cold room in which a refrigerated goods is slidably mounted on telescopic extensions, the refrigerated goods comprises a laterally bordered by two frame profiles plate and in the frame profiles in each case a recess is formed, the one the telescopic extensions in the retracted position at least largely absorbs, especially completely absorbs.

The recess is preferably outwardly, i. to the side walls of the refrigerator compartment, and open at the bottom. This makes it particularly easy to connect the telescopic extensions with the frame profiles.

Preferably, the telescopic extensions are arranged on the side walls of the refrigerator.

The plate may in particular be a glass plate.

The frame profiles are preferably manufactured as extrusion profiles made of plastic or metal, in particular aluminum. The recesses can subsequently be cut into these extrusion profiles, in particular milled.
A plate-like pull-out refrigerated goods should expediently have a railing, so that refrigerated goods can not fall down when moving the refrigerated goods. Such a railing extending at a front and / or rear edge of the plate may advantageously be anchored in the frame profiles.

In particular, the railing can be advantageously anchored by its ends are inserted into an extruded longitudinal channel of the frame profiles. Such a railing can be easily bent from a wire.

Conveniently, the railing and the longitudinal channels extend at a same height above the plate; then two bends at the ends of the wire are sufficient to form the railing.

According to an advantageous development, a shell can be supported on the frame profiles below the plate.

In order to facilitate access to the shell, this is conveniently movable on the frame profiles in the direction of movement of the telescopic extensions.

The frame profiles expediently have horizontal ribs against which edges of the shell rest.

While the plate is preferably mounted just above the telescopic extensions in order to fully utilize the width of the refrigerator compartment, the ribs supporting the tray are preferably at the level of the telescopic extensions.

To ensure that the tray does not slip unintentionally when the refrigerated goods carrier is displaced, the ribs preferably carry in a front portion a protrusion of a material having a high coefficient of friction. The survey only needs be as high as necessary to ensure that not a small part of the weight of the shell rests on the elevation. By being mounted in a forward portion of the ribs, the protuberance remains effective even when the shell is pulled a distance forward from the ribs.

In order to avoid scratching the edges of the shell in contact with the metallic frame profiles, a plastic strip may be attached to the latter to prevent direct contact of the shell with the frame profiles.

Fig. 1 shows a perspective view of a household refrigerating appliance with a body 1 and a door 2. Refrigerated goods in the form of pull-out boxes 4, 5 and a pull-out tray 6 are shown in a refrigerator 3 inside the device. The tray comprises a storage shelf 7 made of safety glass and side edges of the plate 7 enclosing carrier profiles 8, of which only one is visible in the figure. The tray 6 is slidably guided by telescopic extensions, which in the in Fig. 1 shown inserted position of the tray 6 in a lower region of the carrier profiles 8, below the storage tray 7, are hidden. Corresponding telescopic extensions also carry the two pull-out boxes 4, 5. In the in the Fig. 1 empty upper area of the cooling chamber 3 can be further Kühlgutträger, especially in the form of stationary or sliding trays, be attached.

Fig. 2 shows the tray 6 and carrying it telescopic extensions 9 in an exploded perspective view. The metal or plastic, preferably aluminum, extruded carrier profiles 8 have below the storage plate 7 each have a portion 10 of substantially rectangular or trapezoidal cross-section, with a horizontal upper edge 11 which defines a plate 7 clamping groove, and an outer and a lower edge 12, 13, which are cut away on the major part of its length to form a recess 14 which can receive and hide a telescopic extension 9 in the collapsed state.

At the upper edge of a rising above the storage tray 7 web of each support section 8, a hollow bead 15 is formed in the angled ends of a railing of the storage tray 7 forming rectangular bent wire hangers 16, 17 engage. Due to the manufacturing process of the carrier profiles 8, a longitudinal channel runs within the bead 15 parallel to the flank 11 and the plate 7, and it is sufficient to bend pieces of wire at two points at right angles to obtain the bracket 16, 17, which then only in the open ends of the longitudinal channels must be inserted.

As in the presentation of Fig. 4 can be seen, the here designated 44 longitudinal channel is not closed on its entire circumference, but it draws a slot 45 at a normally hidden from the eyes of a user point on the support section 8 along. This slot 45 on the one hand simplifies the production of the carrier profile, on the other hand facilitates the fixation of the wire hanger, either by making it possible to compress the bead 15 so that the wire straps 16, 17 are firmly clamped therein, or by allowing the insertion of adhesive, solder or the like.

The telescopic extension 9 is in Fig. 3 shown in an enlarged perspective view. The telescopic extension 9 is assembled in a conventional manner from two half-extracts, each with an inner rail 20 and 22 and the inner rail 20, 22 with the formation of two longitudinal ball bearings encompassing outer rail 21 and 23. The inner rail 20 is at a Inner wall of the body 1 attached, the rails 21, 22 are fixedly connected to each other, and on the outer rail 23, two adapters 24, 25 are latched for the mounting of the carrier profile 8.

The front, adjacent to the door 2 adapter 24 is injection molded in one piece of plastic and has a cross-sectionally approximately L-shaped body with a resting on the top of the outer rail 23 buffer 26 and a projecting from the buffer 26 upwardly locking projection 27 in shape a letter T, from the cross bar flexible tongues 28 projecting downwards. Non-facing outer sides of the tongues 28 are curved convexly.

The second, remote from the door 2 adapter 25 also has a base body of approximately L-shaped cross-section with a resting on the outer rail 23 buffer 26. The buffer 26 is limited in the longitudinal direction of the telescopic extension 9 by two inclined surfaces 29, respectively extend below the upper edge of the outer rail 23.

From the buffer of the adapter 25 is a Ω- or mushroom-shaped curved leaf spring 30 from whose two ends are positively embedded in the body of the adapter 25.

Both adapters 24, 25 are mirror-symmetrical with respect to a vertical center plane, so that in each case identical front or rear adapters 24, 25 can be used on the mirror-inverted telescopic extensions 9.

Fig. 4 shows in a perspective view from below the support section 8, which for mounting on the telescopic extension 9 of Fig. 3 is provided. On a horizontal bearing surface 31 of the carrier profile 8, which forms the upper end of the recess 14, a window 32 is cut adjacent to the front end of the recess 14, a slot 33 extends to the rear edge of the support surface 31st

When the tray 6 is to be mounted on the telescopic extensions 9 mounted on the walls of the body 1, it is first introduced into the cooling space 3 with an obliquely depending trailing edge, the rear edges of the bearing surfaces 31 of the two carrier profiles 8 on the outer rails 21, 23 the two telescopic extensions 9 between the adapters 24, 25 come to rest. When the tray 6 is pushed deeper into the cooling chamber 3, the trailing edges of the bearing surfaces 31 slide along the rails 21, 23, finally reaching the front inclined surfaces 29 of the two rear adapters 25 and slide upwards thereon. The leaf springs 30 are inserted into the slots 33. When a leading edge 34 of the slot 33 abuts against the leaf spring 30, the tray 6 can be pivoted to the horizontal; the windows 32 are placed so that they fall over the locking projections 27 of the two front adapters 24 in this position.

When the in Fig. 5 shown final position of the tray 6 is reached, the bearing surface 31 is located on the buffers 26 of the adapter 24, 25, the bent tabs 28 of the locking projection 27 are slightly pressed against each other in contact with the edges of the window 32, and an obliquely upward and After ago directed portion 35 of the leaf spring 30 is slightly elastically deflected in contact with the front edge 34 of the slot 33 upwards. The clamping force of the spring is sufficient to keep the storage tray safely even in the horizontal when it is so heavily loaded in a front edge region 36, in front of the two front adapters 24, that the common center of gravity of the tray 6 and the cooling product thereon before the adapters 24 is located.

Due to the tension of the tongues 28 and the leaf spring 30, the carrier profile 8 is fixed without play on the telescopic extension 9. To solve it again, it must first at its front end, that is, the left end in Fig. 5 , be raised. As at the in Fig. 5 To recognize the curvature of the tongues 28 shown, this is only possible by a simultaneous deformation of the tongues 28, that is, it must be overcome an initial resistance. If the tongues 28 yield and the carrier profile 8 is released from the locking projection 27, the probability that the Profile 8 pivots much further than would be required only to release the locking projection 27. However, the force occurring as a result of the rear adapter 25, the leaf spring 30 yield to a large extent, so that damage is not to be feared here.

Fig. 6 shows in a perspective view a second embodiment of a refrigerated goods carrier, which in the refrigeration device of Fig. 1 is usable. The plate 7 and the wire straps 16, 17 are the same as in FIG Fig. 2 shown. The carrier profiles 8 are similar to those of Fig. 2 except for the addition of a horizontal rib 37, which pulls on an inner vertical edge 38 of the carrier profiles 8 approximately at the level of the support surface 31 along. The ribs 37 serve here as a support for horizontal edges 40 of a molded safety glass shell 39. As in the cross section of Fig. 7 to recognize the edges 40 are not directly on the ribs 37, but on a form-fitting anchored in the rib 37, low-friction plastic strip 41 which extends over a majority of the rib 37 in the longitudinal direction thereof.

As further in Fig. 7 can be seen, the shell 39 is held on the horizontal rib 37 slightly sloping downwards, so that essentially only a trailing edge of the shell 39 rests on the plastic strip 41. The reason for this is a survey 42 (see Fig. 6 ), which is mounted in a front portion of the ribs 37 and also supports the edges 40. The projection 42 is made of a rubber-like material with high static friction on the glass of the shell 39, and its task is to prevent slippage of the shell 39 when the tray 6 is abruptly accelerated or decelerated.

The proportion of the total weight of the shell 39, which rests on the elevations 42, increases when the shell 39 from the in Fig. 6 shown, completely pushed under the plate 7 stop position is preferred, so that the shell rests securely on the ribs 37 despite a reduction of the resting surface on the ribs 37. Even if the shell 39 is pulled so far that their focus is a little way in front of the surveys 42, it is still held securely, since then their rear edge tilts high and presses from below against the plate 7, which at the survey 42nd acting friction even further increased.

Fig. 8 shows a variant in which compared to the embodiment of Fig. 7 the rib 37 is displaced downwardly to provide a clearance between the plate 7 and the shell 39, which facilitates gripping a front edge of the shell 39. In order to still keep the tray 39 tilt-proof, a second rib 43 is provided parallel to the rib 37, and the two ribs 37, 43 form a groove in which the edge 40 of the shell 39 is guided with little play in the vertical direction.
Instead of the glass shell 39, a gastronorm container known per se could also be guided on the ribs 37 with or without a lid.
