Description

The present invention relates to a shelf for a refrigerator according to the preamble of claim 1, which is suitable to hang a fixture and a refrigeration device.

There are shelves with suspended built-in known, in which the mounting part has front and rear hooks, each encompassing a front or rear edge of a bottom plate of the shelf and are displaceable on this in the transverse direction. In order to ensure a secure grip on the bottom plate, taking into account manufacturing tolerances or deformations of the insert caused by stress, the hooks of the insert must extend from the front or rear edge of several millimeters to the top of the bottom plate. This makes it difficult to disassemble the fixture when not in use of the bottom plate; Often this is only possible by the bottom plate is removed from the refrigerator and the fixture is stripped in the lateral direction of the bottom plate. If the fixture is moved laterally on the bottom plate, the hooks of the fixture can grind on the edges of the bottom plate and leave scratches after prolonged use.

From the US 3,998,069 a refrigerator container holder and an adjustable air deflection drip tray are known.

KR 10-0364994 B discloses a tablet moving device comprising a carriage for moving a tablet; a front slot groove and a rear slot groove formed at a predetermined distance on an upper tray and a lower tray and having T-shaped cross sections; and a cooling air outlet port for supplying cooling air into the shell as the shell moves. The carriage includes a front slider and a rear slider having T-shaped cross sections for coupling with the front groove and the rear groove and moving in a horizontal direction; and a square C-shaped left rail and a square C-shaped right rail, which are arranged parallel to each other with a guide of the tray to be symmetrically coupled to both ends of each slider.

US 4,775,201 discloses a food container which is hinged to a pair of vertical supports under a shelf of a refrigerator so that the container can be opened for access. The hinges of the container come loose when the container is swung over a predetermined angle, so that the container for cleaning can be removed from the refrigerator. A pair of cables connected between the container and the brackets limits the extent to which the container can be swung open leaving the hinges interconnected. The cords are somewhat elastic to cushion shocks when the container pivots completely upon opening, and they are detachable from the posts so that the container can be pivoted over the predetermined angle for removal.

Object of the present invention is to provide a shelf for a refrigerator, which allows a simplified assembly and disassembly of a component. Another object is to provide a shelf on which a suspended fixture can be moved transversely without leaving visible traces of sanding.

These objects are achieved with a shelf according to claim 1 and a refrigerator according to claim 12. In particular, in a shelf for a refrigerator with a bottom plate and a profile forming a front end for the bottom plate profile on a first downwardly open undercut groove. By engaging in a dependent on the shelf fitting in the undercut of the first groove, the weight of the insert can be introduced into the shelf without requiring a the front frame of the bottom plate encompassing hook is required. Since no parts enclosing the shelf outside are needed to hold the fixture, a displacement of the fixture outside of the shelf can not produce any abrasive marks.

The built-in part acts on a rear end of the bottom plate in any desired manner. Basically, this would be a conventional suspension by means of a hook encompassing the rear end into consideration, since the rear end is not in the field of view of a user and of such a hook left behind sanding marks are barely visible to the user. According to the invention, however, even here such traces completely hide. Therefore, a rear end forming profile for fixing the position of the fitting to the rear end has a second downwardly open groove in which a projection of the fitting engages. The engagement of the projection in the second groove may be in itself form-fitting and thus determine the position of the insert in the depth direction; but it can also be considered alone playful engaging projection together with a second, adjacent to a flank of the rear profile projection of the insert its position.

Preferably, the engagement of the fixture in the first groove in the depth direction of the bottom plate is playful and the attack on the rear end in the depth direction positive. This makes it possible, despite any tolerances in the dimensions of the bottom plate and the built-in part, a contact surface at which touch the fixture and the rear end of the bottom plate and the weight of the fixture is introduced into the rear termination, very narrow.

The engaging in the first groove projection of the insert is preferably pivotally movable in the first groove. This allows attachment of the mounting part, by first only the projection is inserted into the first groove and then brought by pivoting the fitting this at the rear end of the bottom plate in attack.

If the second groove is undercut, the protrusion of the fitting engaging therein may have a locking tongue engaging in the undercut of the groove for anchoring the mounting part.

In order to be able to loosen the installation part from the second groove again conveniently, a wall section is preferably formed on the installation part, which together with the latching tongue A gap bounded, and a latching in the second groove contour of the latching tongue is formed on a side facing away from the gap side of the latching tongue. So it is sufficient that a user presses the latching tongue and the wall portion against each other with two fingers and thereby narrows the gap to pull out the latching contour of the undercut of the groove and so to release the locking.

When the wall portion faces an edge of the rear profile, it can simultaneously serve to fix the position of the fitting in the depth direction on the shelf.

A projecting from the wall portion in the gap projection can limit the freedom of movement of the latching tongue and prevent damage to the latching tongue by excessive deformation.

The profiles forming the front and the rear end are preferably of the same cross section. This is particularly advantageous if the profiles are separate parts from and attached to the bottom plate. These profiles also preferably have mutually facing grooves, each receiving an edge of the bottom plate.

The built-in part preferably has guide rails for a pull-out box. These guide rails can be placed closely adjacent to the bottom plate, so that the height of the insert can be small and the insert takes up little space, if it remains mounted under the shelf even if no drawer is mounted in the guide rails.

To stabilize its shape, the mounting part preferably has a plate extending continuously between the guide rails.

an enlarged detail of the second embodiment.

Fig. 1 is a perspective view of an inventive usable in a not shown refrigerator shelf 1 with it suspended support frame 2 for a (not shown) drawer. The shelf 1 comprises a bottom plate 3 made of glass, which is enclosed in a frame composed of front, rear and side profiles 4, 5 and 6, respectively. The side profiles 6 are designed as injection-molded parts; the front and rear profiles 4, 5 are preferably extruded profiles of identical cross section and may be made of plastic, but in particular also of aluminum.

In the embodiment considered here, the side profiles 6 in the expert in a known manner in the Fig. 1 non-visible pin, which are inserted into chambers of the front and rear profiles 4, 5 form and frictionally engaged. Alternatively, the use of separate corner pieces is conceivable, which engage respectively in chambers of the front and rear profiles 4, 5 and the side profiles 6.

The lateral profiles 6 each have on their outer flanks a recess 7 in which, as in the enlarged view of Fig. 2 to recognize a flat metal part 9 inserted positively and fixed by a screw 8. The screw 8 engages in a longitudinal channel of the rear profile 5, which will be discussed in more detail later. The metal part 9 carries at its rear edge hook 10 for suspending the shelf 1 to a inserted in a rear wall of the refrigerator, not shown rail.

Although not shown in the figure, the side profiles 6 can be fastened in the same way to the front profile by means of a screw engaging in a longitudinal channel of the front profile 4.

The suspended under the shelf 1 support frame 2 is in Fig. 3 shown alone. It comprises a mounted in the state at a small distance below the bottom plate 3 extending central plate 11 which is stiffened by recessed flat ribs or shafts 12. From the lateral edges of the central plate 11 are each two webs 13 down from the sides facing each other horizontal, extending substantially over the entire depth of the support frame extending support ribs 14. In Fig. 3 Only a short piece of one of these carrier ribs is visible. On the support ribs 14 of the pull-out box, not shown in the depth direction of the shelf 1 is displaceable.

Fig. 4 shows an enlarged view of the left front corner of the support frame 2. An upstanding rib 15 at the front edge of the central plate 11 serves on the one hand to stiffen the support frame 2 and on the other hand as a stop in the mounting of the support frame 2, as will become more apparent later. A tab 16 protruding forward over the rib 15 has a wavy course and is stiffened in a rear area by the web 13. A the carrier rib 14 to the front final Threshold 19 serves as a stop that prevents the pull-out of the pull-out box, not shown, that this unintentionally slides forward of the support rib 14.

Fig. 5 shows the same corner in a second perspective view, in which it can be seen that the tab 16 projects beyond the web 13 in the lateral direction.

Fig. 6 is a section through the tab 16 and the front profile 4 in the assembled state of the shelf 1 and support frame. 2

The profile 4 is a square profile of substantially square cross-section. In an outer wall of the profile 4, two slots 37, 38 are formed, of which the one 37 defines a downwardly open groove 21 and the other 38 a side open in the horizontal direction groove 24. It can be seen that the undulating course of the tab 16 serves to engage the tip 17 of the tab 16 in a forward (to the right in FIG Fig. 6 ) directed undercut 20 of the groove 21 to allow. The tip of the tab 16 rests on a slot 37 limiting horizontal portion 35 of the outer wall. The engagement of the tab 16 in the groove 21 is play in the depth direction of the shelf 1, wherein the game by contact of a cranked center piece 19 of the tab 16 with the edges of the groove 21, the contact of the tip 18 of the tab 16 with a front wall 22nd of the profile 4 or the contact of the rib 15 with a rear edge 23 of the profile 4 is fixed.

An edge of the glass bottom plate 3 is held in the laterally open groove 24 of the profile 4 by a sealing profile 25. It rests on a horizontal intermediate wall 36, which separates the two grooves 21, 24 from each other.

Two webs 40 projecting from the intermediate wall 36 into the groove 21 delimit a channel 41 of part-cylindrical cross-section into which the screw 8 fixing the lateral profile 6 engages. Since the channel 41 is open-edge and the webs 40 can escape the pressure of the screw 8 radially outward, the screw 8 can be screwed without excessive force in the originally slightly preformed with slight undersize channel 41 and thereby cut itself on the webs 40 a thread , Due to the placement of the channel inside the profile 4 is a possibly from the penetration of the screw 8 resulting deformation outside the profile 8 not visible.

The remaining cross-section of the profile 4 is occupied by a chamber 42 with walls closed all round, in which a pin 43 of the side profile 6 is inserted. From the intermediate wall 36 from a rib 44 projects into the chamber 42 in front. It facilitates reliable production of a frictional connection between the pin 43 and the profile 4.

The FIGS. 7 and 8 show perspective views of a left rear corner of the support frame 2. Like the front and the rear corners are mirror-symmetrical to each other. As in particular in Fig. 8 can be seen, the central plate 11 is stiffened at its rear edge by a vertical web 26. The web 26 extends from the central plate 11 down to also serve as a stop for the held on the support frame, not shown pull-out box. It prevents so that the drawer comes into contact with the rear wall of the refrigerator and freezes on this or possibly blocks a flow path for circulating in the interior of the refrigerator air

In extension of the web 26 is a wall portion 27 via the longitudinal web 13 to the outside over. The wall portion 27 is curved in its lower portion to the rear, and a latching tongue 28 protrudes from the lower rear edge of the wall portion 27 vertically upward. The latching tongue 28 is elastically deflectable in the depth direction, wherein its freedom of movement is limited to the wall portion 27 through a rib 30 which protrudes from an outer edge of the wall portion 27 into a bounded by the wall portion 27 and the latching tongue 28 gap 29.

A second wall section 31 extends in the extension of the longitudinal web 13 beyond the rear edge of the central plate 11. At an upper edge of the wall portion 31, a single upwardly projecting tooth 32 is formed. From a rear edge of the wall portion 31 is a flat, parallel to the web 26 tab 33 upwards.

The FIGS. 9, 10 show two sections through the rear left corner of the support frame 2, anchored to the rear profile 5 of the shelf 1. The rear profile 5 has the same cross section as the front profile 4, so that the same reference numerals used to denote its components and not in detail be described again.

The cut of the Fig. 9 extends through the latching tongue 28 and the wall portion 27. A rearwardly projecting tip 34 of the latching tongue 28 engages in the undercut 20 of the downwardly open groove 21 and rests on the lower wall 35 of the profile 5. The weight of the support frame 2 and any parts hanging thereon is introduced into the lower wall 35 via the latching tongue 28, which is essentially loaded only by tension.

It can be seen that when a user squeezes the catch tongue 28 and the wall portion 27 between two fingers of one hand, the tip 34 is released from the bottom wall 35 and thus the rear portion of the support frame 2 can be released from the profile 5. Excessive bending of the latching tongue 28 is excluded because the latching tongue strikes the rib 30 before leaving its elastic deformation area.

Unintentional release of the support frame from the profile 5 is characterized by in Fig. 10 shown in section form of the wall portion 31 in cooperation with the profile 5 excluded. As can be seen, corresponds to the distance between the tooth 32 and the tab 33 exactly the width of the bottom wall 35, so that when the latching tongue 28 is latched in the undercut 20, by simultaneous engagement of the tooth 32 in the groove 21 and concerns of Tab 33 is held on the back of the profile 5 of the support frame 2 to the profile 5 in the depth direction positively. Thus, despite the play-bearing engagement of the support frame 2 in the front section 4 of the support frame 2 is immobile in total on the shelf 1 in the depth direction. Only a shift along the profiles 4, 5 is possible. Due to the positive connection between tooth 32 and tab 33 on the one hand and wall portion 31 on the other hand, a secure locking of the support frame 2 on the rear profile 5 is possible, even if the surface on which the tip 34 of the latching tongue 28 overlaps with the wall 35, is very narrow , In particular, the overlap area can be significantly narrower than the freedom of movement of the Tab 16 in the groove 21 of the front profile 4 corresponds. Therefore, the demands on the manufacturing tolerances of the support frame are low, which makes its production simple and inexpensive.

Fig. 11 shows the shelf 1 and the support frame 2 after releasing the locking of the support frame 2 on the rear profile 5. In this state, the support frame 2 is pivotable about one of the two engaging in the groove 21 of the front profile 4 tabs 16 axis. In the in Fig. 11 shown oblique position, it is possible to pull the tabs 16 out of the groove 21 of the front profile 4 and the support frame 2 completely separate from the shelf 1 and remove it from the refrigerator. Conversely, the mounting of the support frame 2, by this first with the in Fig. 11 shown orientation introduced into the refrigerator and its tabs 1 are inserted into the groove 21 of the front profile 4. Subsequently, the rear portion of the support frame 2 is folded up to thereby defined on the front profile 4 pivot axis, optionally shifted in the depth direction so that the tabs 33 come to rest on the back of the rear profile 5, and then the support frame 2 from below against the rear Profile 5 is pressed so that the latching tongue 28 engages in the groove 21 and locked therein.

At the in Fig. 12 shown shelf is the glass plate 3 replaced by a grid 45 of intersecting wires. The frame surrounding the grating 45 is the same as in the embodiment of FIG Fig. 1 , Fig. 13 shows a portion of the grid 45 and the front profile 4 in perspective and in section. The width of the groove 24 is designed to receive both a wire 46 parallel to the profile 4 and crossing wires 47 of the grille 45.
