Description

The invention relates to a refrigerator with one or more guide elements for drawer-like extendable shelves according to the preamble of claim 1.

Domestic refrigerators, such as Refrigerators, freezers, refrigerators / freezers or the like have shelves such as e.g. Abstellplatten, support plates, Abstellgitter or the like, on which the refrigerated goods is stored. A part or all of the shelves can be designed, in particular, as glass plates, on which, if appropriate, at least front and rear sides of a profile part are placed. The front profile part protects the glass edge, the rear profile part can project upwards to prevent the goods to be cooled is pushed to the back side of the refrigeration appliance, this touches and freezes on it. In part, these shelves or shelves are drawer-like displaced or attached to the side walls of the refrigerators attached to ensure easier accessibility of the refrigerated goods.

US 5,642,924 discloses a refrigerator according to the preamble of claim 1. It is known to realize these drawer-like extracts on telescopic extensions with metal rails. An example of this is in the DE 102006018203 A1 described. These telescopic extensions are of high quality but very expensive to manufacture. For more cost-effective solutions slip or slide, for example, framed by plastic frame glass plates or plastic floors between groove-like recordings, which extend along the total length of the side walls of the respective household refrigeration appliance and serve as a guide for the respective plastic frame. However, this solution is quite difficult. In addition, these pull-out constructions seem too bulky in practice and take away a lot of space in the refrigeration unit.

The invention is based on the object, a refrigeration device with slidably mounted on the side walls, drawer-like extendable shelves, especially storage shelves, cost-effective, secure, discreet and smooth perform. The object is achieved according to the invention by a refrigerator with arranged on the side walls one or more guide elements for drawer-like extendable shelves with the features of independent claim 1. Preferred embodiments are the subject of the dependent claims.

According to the invention, one or more holding projections are arranged on the respective side wall. The respective retaining projection preferably engages from below onto the shelf and carries it in such a way that it in particular rests loosely on a support surface of the respective holding projection. As a result, the shelf is in the extension direction, in particular horizontal displacement direction, slidably mounted. In this case, at least one guide element is arranged on one or more side walls or at least one holding projection, which extends only along a partial length of the total depth extension or total depth length of the respective side wall and limits the movement of the shelf transversely, in particular perpendicular, to the displacement direction. The guide element otherwise provides a tilt protection for the shelf in its back and forth sliding on the support zones of the retaining projections.

In particular, when the shelf is pulled out in its end pull-out position and loaded with refrigerated goods, the respective guide element secures the shelf against forward-tilting. For this purpose, it can be particularly expedient to assign one guide element each to a holding projection in the rear side wall region of the inner container of the household refrigerating appliance. In order to prevent tilting of the shelf when it is positioned in its Einschubendposition in the inner container, and loaded with refrigerated goods, it may be particularly appropriate to assign each in the or front side wall portion of the inner container depending on a guide element each a front retaining projection. According to an expedient embodiment of the invention, it may possibly already be sufficient for a simple anti-tip device of the shelf to provide only a single guide element on one of the two side walls.

By combining these very simple and inexpensive elements, the full functionality of a high quality drawer can be achieved with low production costs. By restricting the extension of the respective guide element to only a small part of the depth of the respective longitudinal side wall but retaining full functionality, it is possible to make the side wall flat along a large part of its surface -the neatly guided along its respective longitudinal edge in the depth direction and / or extension direction in the respectively associated guide element, but not clamped along its Gesamttiefenlängerandandand. As a result, it is easily displaced, the risk of jamming is reduced and thus the risk of damage to the respective side wall of the inner container of the household refrigerating appliance. In addition, a side wall (viewed in the depth direction) with one or more shorter guide elements, in particular if it is designed flat or planar surface, easier to clean and visually appealing. Also, the entire interior of the inner container of the household refrigeration appliance acts larger if the emerging from the respective side wall, or attached to the respective retaining projection guide element smaller, especially in the depth direction is shorter than their total depth. In addition, due to the shortening or locally limited extent of the respective guide element, the removal possibility for the respective shelf can be made simpler. Thus, by leaving the surface of the respective side wall of the inner container of the household refrigerating appliance predominantly free of laterally protruding projections except for the respective locally limited holding projection, a substantially planar inner wall is provided. In particular, the interaction of at least one guide element and at least one retaining projection per side wall, preferably two retaining projections per side wall, while offering all the functionality that is sufficient for an extendable shelf. By realizing the respective guide element as a short component with a locally limited extent on the respective side wall or the respective holding projection, it is also possible and advantageous to form a shelf, preferably a glass plate, laterally frameless. The respective open in the depth direction extending longitudinal side of a shelf, preferably a glass plate is visible due to the shortness of the guide elements over a wide areas and also usable. This also gives a visually appealing impression of a large, high-quality interior of a household refrigeration appliance. In particular, even if a cover strip has been omitted at the front, transverse axial end edge of the shelf, the outer contour shape of the shelf appears overall as frameless. This construction is particularly advantageous if a glass plate is used as the shelf.

The respective guide element has, according to an expedient development of the invention, a depth of at most one-tenth of the total depth of the respective length Sidewall up. As a result, the respective guide element hardly or not at all falls on the surface of the respective side wall.

Preferably, at least one retaining wall, which are spaced apart from each other in the depth direction, are arranged at the same height on at least one side wall, so that the retaining projections of both side walls together span a substantially horizontally arranged plane, on which the shelf then rests. The guide element, which fixes the shelf from above and thus prevents deflection of the shelf transversely, in particular perpendicular to its extension or displacement direction, ie folding it up when moving at least over a predetermined displacement area, in this example, preferably only on one of the two holding projections arranged per longitudinal side of the inner container. By placing at least one longitudinal side edge of the shelf onto at least two holding projections, a larger pull-out area can be realized with very short holding projections. The shortness of the guide formed by holding projection and guide element ensures that the shelf is easy to remove. It does not first, as in the conventional systems, be extended over the total depth of the side wall until it can be removed, but can, after he has overcome the guide element, simply taken away, in particular taken upwards. The respectively arranged on opposite side walls of the refrigerator retaining projections and the respective guide member may be preferably realized as a very simple plastic parts. In particular, the retaining projections may be formed on the respective side wall of the inner container, that is to be extended, if this has been made of plastic by deep drawing. The sidewall can be made flat over much of its surface.

The retaining projections are preferably constructed and arranged so that a shelf supported laterally thereof rests on at least two points or bearing zones of its respective lateral edge, which are spaced apart by more than half the depth of the shelf. The holding projections themselves span or occupy, viewed in the depth direction, preferably only a maximum of one tenth of the length of the side wall. In addition, a breakpoint of the rear retaining projection is preferably arranged at a distance from the rear wall, which corresponds approximately to the depth of extension of the shelf. This ensures that the shelf is always well supported, even if it is pushed forward or backward, as long as it rests on the extremely short holding projections, but at the same time the side wall can be largely flat.

In a particularly cost-effective manner and thus particularly advantageous embodiment, the retaining projections are tightened during deep drawing of the side walls of the refrigerator to this. As well as the holders for the conventional, firmly positioned shelves these holding projections invention are easily mitgeformt in the production of the side walls; additional installation effort can be avoided. To make this possible, the retaining projections are constructed as simple geometric shapes, such as crescent shape or pitch circle or partial disk shape.

Preferably, the retaining projections are curved, they stand out as cams or nubs from the side walls. This is contrary to the manufacturing process. There is no danger that thin spots in the plastic of the inner container occur, as they may occur in the formation of rectangular projections. In addition, the curved structure of the projections simplifies the insertion of guide elements which are arranged on the shelf. Preferred here is a crescent-shaped configuration of the cams. This is very easy to pull and also easy to clean.

In a preferred embodiment, the retaining projection is designed as a rotatably mounted roller. This is preferably formed kreiszylinderformig. By the co-movement or rotation of the role in the extension movement of the shelf a particularly smooth sliding of the shelf is made possible during its extension movement. As a result, jerking, which usually leads to the displacement or overturning of refrigerated goods during the extension, can be completely prevented. In addition, this scouring a shelf, especially glass shelf is avoided on a holding projection made of plastic and thus prevents damage to the retaining projection. This smooth sliding can preferably be further assisted by the fact that the movable roller itself, its surface or a friction element mounted on it or attached to it or integrated (such as a rubber ring) of a material with a high coefficient of friction, preferably Rubber or two-component material, is molded. In particular, the coefficient of friction of the roller is chosen to be greater than the coefficient of friction of the sliding base to be stored shelf. Alternatively, it may be sufficient if the respective role is certain. Also, by the stapled or curved outer contour of the roll in its upper 12 o'clock position only a support point or a localized support zone for the shelf provided over this slides away in the tangential direction relative to the outer circumference of the role in its extension movement.

Preferably, at least one holding projection, preferably all holding projections, on each side wall on a side wall arranged on the transverse spacer, the upwards over the guide surface on which the respective shelf rests on the holding projection, and the shelf thus from direct contact to the respective side wall itself keeps. As a result, the shelf slides when moving not on the entire side wall, but only along the spacer, so it is easier to move than if it rubs on the entire side wall and beyond damaging the side wall can be prevented. The spacer may additionally perform the function to center the shelf and compensate for any existing Abnahmeschräge the wall or other dimensional tolerances of the inner container of the refrigerated goods container of the refrigerator and / or the respective shelf. Preferably, the respective transverse spacer is formed by a strip member extending in the depth direction along the depth of the retaining projection between the substantially planar surface contact zone of the retaining projection and its associated side wall as a protruding in the height direction pedestal. The respective transverse spacer extends substantially rectilinearly and parallel to the resting longitudinal side edge of the shelf. Between the overlying longitudinal side edge of the shelf and the inside of the transverse spacer while a defined transverse play is provided so that the shelf as possible without abutting the transverse spacer in the depth direction or extension direction can be easily moved back and forth.

In a further advantageous embodiment, at least one guide element is likewise shaped as a pulled projection in the respective side wall. This guide projection may, like the attracted retaining projection curved, in particular crescent-shaped or part-circular disc-shaped, which also give the benefits already mentioned. On the side wall so that the guide element is very simple and inexpensive to implement without a further assembly step, such as would be necessary, for example, when attaching a guide rail on the shelf, would be incurred. Nevertheless, this easily realizable guide element, which is arranged on the inner container of the household refrigerating appliance itself, meet the full functionality that is necessary for a controlled guided extension movement of the shelf and prevent any tilting thereof during the extension movement.

Preferably, the guide projection is at the depth of a, preferably the rear, retaining projection, this offset in the height direction offset by a predetermined height distance opposite, so that the shelf can be inserted into the groove formed by these two opposite projections. This opposing arrangement of the projections facilitates the insertion of the shelf and provides a very stable leadership.

In a further advantageous embodiment, at least one retaining projection on at least one guide element for guiding the shelf during its extension movement and thus to prevent a folding up of the shelf. The retaining projection may for this purpose preferably be designed as double cams, wherein a projection of this double cam is located below the shelf and this carries, the other is located above the shelf with a low Högenabstand to this and leads. Such a double cam can be easily formed in a side wall or attached as an additional component in a corresponding Hinterlegteil on a molded projection or plugged into a bulge of the side wall.

In a preferred embodiment, the respective guide element protrudes at least partially over the lateral edge zone of the respective shelf. It is designed as an overhang, so to speak. The guide element is preferably arranged at a distance from the shelf in the vertical direction. That is between the shelf and guide element exists an air gap that allows unhindered sliding of the shelf during its extension movement. The guide element allows the shelf to pass unhindered as long as it is moved only forwards or backwards. First in a vertical movement of the shelf, the guide element limits the freedom of movement of the shelf and thus prevents it from tilting.

The overhang is preferably designed and arranged such that its free end forms a transverse distance to the side wall. This transverse distance creates a range of motion within which the overhang can be moved from a guide position to a removal position. In the guide position, which corresponds to the rest position of the overhang, this projecting above the shelf and prevents the shelf from dodging to the top. From this, the overhang can be moved into a removal position in which it comes to rest on the side wall and in which it releases the shelf, so that it can be removed to the top. Such, preferably as a plastic element advantageously producible, guide element ensures good guidance of the shelf, but also allows easy removal of the shelf, not only still by moving the shelf, but also to the top, even with not fully extended shelf. For this purpose, the overhang preferably has a maximum projecting width, which corresponds to the distance between the shelf and the side wall, as soon as the overhang has been moved into its removal position, when the overhang is thus pressed completely against the wall.

In a further advantageous embodiment, the guide element is at least partially elastically resiliently formed on a retaining projection or placed on this. But it can also be attached to the side wall. Preferably, the overhang is elastically resilient. In this embodiment, due to its elasticity, the overhang can simply be moved by means of a slight pressure movement to the respective associated side wall for removal of the shelf, so that it releases the shelf and this can be moved upwards. In its rest position, the overhang extends beyond the outer edge area of the shelf and holds it as soon as it, for example, due to uneven load by means of refrigerated goods, wants to escape to the top. The overhang can be easily formed as a resiliently movable plastic part to the retaining projection or the side wall. Due to the resilient design of the respective guide element, it is also possible in an advantageous manner that this serves both the leadership of the shelf by including this between itself and the support surface on the respective retaining projection, as well as a stop element can serve, on which a projection on the shelf, preferably the rear rail, abuts as soon as the extraction process is completed. To remove the shelf, the guide element can be pushed away due to its resilient design to the side wall or upwards, thereby releasing the abutting projection of the shelf or the shelf itself. Such a retaining projection with molded guide element thus assumes three functions. On the one hand it serves as a support of the shelf, on the other he leads this during the extract and finally it forms a resilient, releasable stop. Thus, almost all the necessary functionality for the drawer-like removable shelf can be realized via a single element and thus particularly cost-effective. In addition to this, it is expediently arranged on both sides only a further holding projection for the support of the shelf in the depth direction. The advantage of the multifunctionality clearly outweighs the disadvantage that results from the more complicated design of the holding projection with integrally formed guide element. Such a projection is preferably designed as a plug-in, latching or screwed or otherwise attachable projection which is inserted into a receptacle provided for this purpose on the side wall.

Preferably, a resilient guide element can be arranged on both holding projections of a side wall offset in the depth direction. As a result, a folding away of the shelf can be prevented both to the front and to the rear, especially when the shelf is loaded with refrigerated goods.

In a further preferred embodiment, the resilient region of the guide element tapers upward in the vertical direction, perpendicular to the extension direction. This gives the overhang of the guide element a wedge-shaped shape, so that the shelf when inserting from above, from the narrow-running side, can simply slide over this on the retaining projection, but then enters the Kuhle or groove below the projection of the overhang wherein the overhang jumps due to its spring tension in its rest position and thus according to a barb on the shelf and limits its freedom of movement to the top.

In a further advantageous embodiment, the guide element is designed to be resilient and attached to the holding projection, for example, by clamping with a positive fit. This opens up the possibility to continue to form the retaining projection as an attracted projection of the side wall, but nevertheless achieve the full functionality by simply placing additional elements by the retaining projection is an attachment to the guide element and releasable stop is formed. The functionality of a spacer can be achieved via the shape of the attachment.

In addition, at least one laterally arranged projection is preferably attached to the shelf, which abuts the extract of the shelf at a present on the inner container of the refrigerator stop element, which is preferably realized in the holding projections, to limit the pull-out movement and to prevent falling out of the shelf. In particular, a lateral projection acting as a stopper on the shelf is arranged so that, when the shelf is pulled out, it abuts against a stop arranged on the inner container, preferably the holding projections themselves. Due to the interaction of these very simple trainees, relatively short retaining projections and guide elements and stop element, a cost-effective, extendable shelf can be realized in a household refrigeration appliance, which prevents the folding up of the shelf during the extension movement and is easy to use and removable.

In a preferred embodiment, located on the back of the respective shelf a stop which abuts at fully extended shelf to the holding projection or particularly advantageous to a guide element of the rear holding projection. This prevents in a particularly simple manner that the shelf is extended beyond the point where it rests stable on the retaining projections and thereby tilts forward. Preferably, the rear stop is identical to a spacer bar, which may be provided on the back of the shelf expediently to prevent the stored on the shelf refrigerated goods reaches the back of the household refrigerating appliance and freezes there. By this rear spacer rail is designed so that it can be used as a stop, can be dispensed with the attachment of a further, additional stop. The rear spacer rail thus performs a dual function. Both stop and it abutting element need not be realized by additional parts but can be effected as additional functionality over existing parts.

In a further preferred embodiment, a abutting projection is arranged laterally on the shelf, for example, infected or molded, which emerges over the shelf and thus stops the shelf as soon as it meets the front retaining projection. Thereby, the extension movement of the shelf is stopped once the maximum extension length is reached before the back of the shelf from its respective rear guide, formed e.g. by the two spaced apart in the height direction or opposite projections, slides out and could tilt away. As a stop here serve the front retaining projection, which is easier to understand for the user. A set on the shelf or existing rear bar, which keeps the refrigerated goods, which is stored on the shelf at a distance from the rear wall of the refrigerator, should preferably be shortened laterally in this embodiment, so that the bar can slide past the guide projection. Finally, it should also be mentioned that it is possibly also possible, of course, the entire guiding and holding elements of the extendable shelf not on the side wall of the refrigerator itself, but on an acting as a side wall intermediate wall of the inner container of the refrigerator, which, for example a wall formed by a shelf can be arranged.

Other developments of the invention are given in the dependent claims. The invention and its developments and advantages thereof are explained in more detail with reference to drawings.

Elements with the same function and mode of action are in the FIGS. 1 with 9 each provided with the same reference numerals.

The Fig. 1 shows a section of a household refrigerating appliance, in particular refrigerator, on which the two side walls 1 and 2, and the rear wall 3 of the inner container 94 of the refrigerator can be seen. The inner container 94 encloses a cooling and / or freezing space 89. In this at least one shelf as here 4, for example, in extracting 90 is mounted extendable or slidable. The pull-out direction 90 runs parallel to the depth direction 91 of the inner container. The shelf 4 is arranged in a horizontal position plane. He is here in the embodiment, in particular designed as a glass plate. The horizontal positional plane for the shelf 4 is formed by the depth direction 91 and the orthogonal transverse direction 93. The height direction 92 runs perpendicular to this horizontal positional plane. All three directional vectors 91, 93, 92 thus form a Cartesian coordinate system as the reference axis system. At the first, left side wall 1 is a front retaining projection 5 and a rear retaining projection 6, which as a solid, curved Projections in the production of the side wall 1 made of plastic to be molded. Symmetrically arranged on the side wall 2 are corresponding front and rear retaining projections 7 and 8. The retaining projections 5 - 8 support the shelf 4, which rests on its guide surface. Above the rear holding projections 6 and 8 respectively guide projections 9 and 10 are provided, which together with the lower retaining projections 6 and 8 form a groove in which the preferably designed as a glass plate shelf 4 can be inserted and along which he in his extension movement in the extension direction so slides. The double cams formed from the projections 6 and 9 as well as 8 and 10 thus each form a guide element, which guides the shelf 4 in its pull-out movement at its side edge and prevents it from escaping upwards. Thus, the shelf 4 can not tilt forward, even if it is fully extended and loaded with heavy refrigerated goods. The guide projections 9 and 10 can also like the holding projections 5 - 8 are pulled out of the side wall 1 and 2 made of plastic. As an element abutting on the front holding projections, a stop projection 11 is provided in this embodiment, which, for example, formed as a plastic clip, is laterally clamped to the shelf 4.

At the back of the shelf 4 is a spacer bar 12 which holds on the shelf 4 stored refrigerated goods from the rear wall 3. The front holding projections 5 and 7 have lateral spacers 13 and 14, which protrude beyond the guide surface and attack the side of the shelf 4 and keep it at a distance from the side walls 1 and 2. The designed as a glass plate shelf 4 is located in the in the Fig. 1 shown extract position stable on the retaining projections 5 - 8 and serves to receive refrigerated goods. In this pull-out position is its trailing edge extending with the transverse direction 93 spacer bar 12 in the region of the depth position of the two rear retaining projections 6.8 with the associated guide elements 9.10. But he can, for example, when it is loaded, are also moved to the rear wall 3 in the depth direction 91. The lateral glass surfaces slide along the grooves of the double cams 6/9, 9/10 formed by the projections 6 and 9 as well as 8 and 10. The shelf 4 can, as can be seen in the figure, always be pushed so far forward until the stop projection 11 abuts the front retaining projection 5. In this position, the extension movement of the shelf 4 is stopped before the glass plate from the rear holding projections 6 and 9 and 8 and 10 can slide out. In order to move the shelf 4 beyond this pull-out position and remove it completely from the refrigerator to the front, the shelf 4 in its pull-out position in the front region is slightly raised in the height direction 92, ie vertically to its positional plane 91, 93. so that it moves forward above and lifted the stopper projection 11 on the front retaining projection 5 and the shelf 4 can be pulled on this sliding forward. By lifting the front retaining projection 5 releases the shelf 4 so that it can be pulled out of the refrigerator. In particular, the shelf 4 can be slidably moved in a drawer-like manner between the rear and front retaining projections by a depth of such depth, which essentially corresponds to the depth spacing of the front and rear retaining projections from one another.

The Fig. 2 to 4 show on the basis of schematic partial sections, another example of an inventive household refrigeration appliance. In Fig. 2 is a portion of the side walls 21 and 22 and the rear wall 23 of the inner container 94 can be seen. Again, an extendable shelf 24 is supported by front and rear retaining projections 25-28 disposed on the side walls 21 and 22. However, these holding projections are not formed together with the side walls 21 and 22, but attached to this. As a result, they can be formed as individual parts, which allows a more complex design and also a free choice of material relative to the plastic of the inner container 94. Thus, the front retaining projections 25 and 27 on transverse spacers 29 and 30 which hold the shelf 24 at a transverse distance to the side walls 21 and 22. The respective transverse spacer 29, 30 is formed by a strip element which extends in the direction of depth 91 between the horizontal, substantially planar surface contact zone of the respective front retaining projection 25, 27 and its associated side wall 21, 22 as in the height direction 32 protruding base. The respective transverse spacer runs substantially rectilinearly and parallel to the respective longitudinal side edge of the shelf. In addition, however, a guide element 31 and 32 is integrally formed on the rear holding projections 26 and 28, which forms together with the rear holding projections 26 and 28 a groove in which the shelf 24 is guided while it is pulled out in the extension direction 90. The rear free end of the respective guide member 31 and 32 is resilient and loosely viewed at a small lateral distance in the transverse direction 93 to the side wall 21 and 22. Its front end 97 is articulated on the base-like transverse spacer 29 or 30 such that a bending axis in the vertical direction or height direction 92 results. The respective guide element, such as 31 or 32, extends from its fixed deflection end with a first section parallel to the plane of the layer the associated side wall 21 to the rear, then passes into a central portion, which runs away from the first portion obliquely away from the side wall 21 toward the interior and finally runs at its freely projecting deflection end approximately parallel to the longitudinal plane of the side wall 21ausaus. In the first diet, it thus has an S-shaped geometry shape. The middle section displaces the freely projecting deflection end section relative to the deflection section by a predeterminable transverse distance from the side wall 21 and thereby projects over the shelf 4, the longitudinal side edge of which is laterally bordered by the upwardly projecting inner edge of the transverse spacer 29 or 30 and thereby laterally moved back and forth of the shelf in the extension 90 and depth direction 91 is performed. For slidable mounting of the shelf 4 on the plane contact areas of the retaining projections 25,26, 27, 28 is sufficient lateral clearance between the inner boundary edges whose lateral transverse spacers 29, 30 and the respective longitudinal side edge of the shelf 4 is provided. The respective guide element is thus generally considered as a wing-like protruding blood spring element. Of course, other geometric shapes for the respective guide element are possible, which cause a laterally flexible overhang or over-cranking for a side edge zone of the shelf. The respective Führungslement can be pressed due to its resilient elastic training for removal of the shelf to the side wall 21 and 22, whereby the guide element is very narrow when pulling out and thus freed in the transverse direction 93 space to pass for the back of the shelf arranged spacer bar 33. As a result, the shelf 4 can be taken out of the inner container. Before the guide member 31 and 32 is pressed against the side wall, this resilient element serves as a stop for the rear spacer bar 33. Only when a leading, lateral pressure force on the free end of the respective guide element such. B. 31 in the transverse direction 91 is exerted on the associated inner wall 2, it is deflected away from the shelf so that its overhang is canceled. In particular, this makes it possible to simply remove the shelf using a corresponding lifting force upwards from this type of holder, since the wing-like guide elements are pushed away laterally by the shelf. In the reverse manner, the shelf can also be used from above in his brackets. In this way, the handling for inserting and removing the shelf is greatly facilitated.

In Fig. 3 , which made a detail of Fig. 2 with only one side wall 21 and a small portion of the rear wall 23, the retaining projections 25 and 26 can be seen more clearly. In this figure, the shelf 24 is seen in the extended position, in which the spacer bar 33 abuts against the guide member 31. It could be achieved in that the resilient end of the guide member 31 against the side wall 21 z. B. was pressed by hand. Namely, once the guide member 31 is pressed against the side wall 21, the guide member 31 is not wider away from the wall than the spacer 29 of the front retaining projection 25. Thus, the shelf 24 can be removed both forward and upward.

As in Fig. 4 In a detail view of the rear holding projection 26, seen more clearly from the rear wall 3, the guide element 31 is slightly S - shaped. The front end 34 of the guide element 31 facing the refrigerator door in the extension direction 91 is connected to the rear retaining projection 26. However, its free rearwardly projecting end portion 95 is arranged so loosely and connected only over its front portion 34 with the retaining projection 26 so that it forms a transverse distance to the retaining projection 26 and even in the height direction an air gap 36 to the inserted, displaceable glass plate of the shelf 24 , whereby a possible frictionless extraction movement is possible. As long as the spring element 35 is not pressed against the side wall 21, it is due to its spring tension slightly from this in the transverse direction 93, thereby projects beyond the shelf 24 and thus prevents an evasive movement of the shelf 24 upwards. Alone through the combination of these elements of the retaining projection 26 creates the leadership of the shelf 24th

The Figure 5 shows a further embodiment of the household refrigerating appliance according to the invention, wherein again a cutout with a side wall 41 and a part of the shelf 42 can be seen. This variant is of the in the Fig. 2 to 4 shown embodiment. Again, the shelf 42 is located on a retaining projection 43 and is supported on the plane support zone,. However, the retaining projection 43 is designed as a one-piece long rail. The distance of the shelf to the wall is held by spacers 44 and 45, which are integrative components of the guide elements 46 and 47. The guide elements 46 and 47 are integrally formed on the strip or rail-shaped holding projection 43. They are according to the guide elements 31 and 32 are formed and form the guide with their, the glass plate of the shelf 42 in the height direction 92 superior spring elements 48 and 49. In this example, spring elements 48 are arranged at the front, which overhang the shelf 42. As a result, the shelf 42 is advantageously secured against tilting down to the rear, when the shelf is inserted completely in the depth direction 91 in the inner container.

The Fig. 6 and 7 show embodiments in combination with the embodiments according to FIGS. 1 to 5 the household refrigerating appliance according to the invention can be used. In Fig. 6 is again a section of the inner container with a side wall 51 and a rear wall 53 to see. Fig. 7 schematically shows in enlarged representation as a detail a rotatably mounted roller as retaining projection. This embodiment is basically with the in the Fig. 2 to 4 shown comparable and shows the shelf 54 in the removal position. Again, the shelf 54 is located on a front retaining projection 55 and a rear retaining projection 56 and is supported in its pull-out position on the plane-like support zone. From a spacer 59, which is arranged on the front retaining projection 55, the shelf 54 is kept at a distance from the side wall 51 and guided by a guide member 61, which is part of the rear retaining projection 56. The guidance of the shelf by the guide member 61 is clearer in the Fig. 7 to see that shows a section of the shelf 54, which is in the pull-out position and between the rear holding projection 56 and the guide member 61, which is the shelf 54 laterally surmounted partially out. In this embodiment, the retaining projections 55 and 56 are formed roller-shaped. Her standing with the shelf 54 in contact surface is curved, preferably round shaped, so that the shelf 54 rests only on a very small contact surface and thus easily slides when it is pulled out. In particular, the respective roller 55, 56 rotatably mounted, which greatly facilitates the extraction movement of the shelf due to the low friction. In the Fig. 7 is also the triple functionality of the retaining projection 56 clearly visible. The holding projection 56 supports with its roller-shaped support surface the shelf 54 from below, limited by means of its guide member 61 whose freedom of movement upwards and also serves as a stop for the spacer bar 63 which abuts him as soon as the shelf 54 is fully extended. Just like that in the Fig. 2 to 4 shown guide member 41, the guide member 61 has a spring element 64, which, however, expires freely in this example in the vertical direction 92 upwards. It has at its freely projecting end on a circular overhang, the inner edge is substantially parallel to the position of the shelf level. Thus, this overhang has an undercut which extends essentially in a straight line and parallel to the male longitudinal outer wall of the shelf 54. This spring element 64 is spaced in its rest position to the side wall 51 and projects beyond an inserted glass plate laterally in the transverse direction 93. It can be pressed to remove the shelf 54 to the side wall 51, wherein it then viewed in the transverse direction 93 of the width of the Spacer 59 corresponds, so that the shelf 54 slide past the spring element 64 and can be removed upwards. The spring element 64 runs arched, wedge-shaped upwards out, so that the shelf 54 can not only be inserted from the front when inserting, but also can be pushed down from above over the spring element 64. Due to its shape, the spring element 64 is pressed when placing the shelf 54 to the side in the direction of the side wall 51 and lets this happen. As soon as the shelf 54 rests on the retaining projection 56, the lateral edge of the shelf 54 comes to lie in the Führungskuhle 65 of the guide member 61 and the spring element 64 projects beyond the shelf 54. Between shelf 54 and spring element 64, however, remains an air gap 66, viewed in the height direction 92, which allows a simple sliding of the shelf 54 when pulling out.

The Fig. 8 shows a further embodiment, which is essentially that of FIGS. 6 and 7 However, wherein the retaining projection 500 is provided with a rotatably mounted roller 501. The rotatable roller 501 is formed in particular circular cylindrical. The rotatable roller 501 is in communication with the flat circular cylindrical spacer 502 which, like the spacer 59 of the previous embodiment, keeps the shelf not shown here at a distance from the side wall of the refrigerator. On the rotatable roller 501, a rubber ring 503 is mounted or applied. The rubber ring is here in the embodiment of FIG. 8 in particular integrated into the circular cylindrical geometry shape as a circular ring or torus element largely flush, so that a largely uniform flush cylindrical Zylindermantelau ßenoberfläche is formed.

Alternatively, if necessary, it may be sufficient if the roller is fixedly mounted. Even then, such a role in its 12 o'clock position or dead center only one support point or only a locally limited support zone ready, over which or slides the shelf in the tangential direction relative to the circular outer periphery of the roll when pulling or pushing away. This is accompanied by a reduced friction for the shelf in its extension movement or insertion movement, which allows a smooth sliding of the shelf. This has a higher coefficient of friction than the plastic from which the roller 501 and thus ensures an extremely smooth smooth sliding of the shelf when pulling, as this of the rotating rubber ring 503 due to the greater adhesion in the tangential direction relative to the upper support point of its rotational movement better in tangential direction is taken.

Another solution that provides the full functionality of support and guide, but still allows the extraction of the retaining projection from the side wall is in the Fig. 9 to see. In this embodiment, which can be used in combination with the previous embodiments, a rear retaining projection 76 is pulled out of the side wall 71 as a curved retaining projection. However, the guide member 81 is not formed on the retaining projection 76, but has a support member 87 which is shaped so that it surrounds the rear retaining projection 76 in a form-fitting manner. Thus, the guide member 81 can be firmly clamped on the retaining projection 76. In order to ensure a more secure support or latching of the support member 87 to the rear retaining projection 76, a clamping spring 88 is additionally formed on the, the underside of the retaining projection 76 facing side of the support member 87, which presses against the retaining projection 76, this of engages behind and thus fixes the guide member 81 more stable on the retaining projection 76. Generally expressed in this embodiment of FIG. 8 clipped or clamped the guide element as a separate component on the retaining projection. As a result, another material, in particular plastic, can be used as the retaining projection for the guide element. The guide element 81 itself is according to the previous example of FIG. 7 designed as a vertically upwards expiring, free-standing spring element, which projects over the shelf to height clearance.
