Description

The The present invention relates to a refrigerator, in particular a domestic refrigerator such as a fridge or a freezer, according to the generic term of claim 1.

such Refrigeration appliances point a refrigerator on, by sidewalls and a back wall is limited, and at least one shelf, which extendable on at least one projecting from a side wall in the refrigerator Rib or rail or bar is stored. With some devices is provided on the shelf a Gleitnocken, and at least one Rib is provided a stop cam. The arrangement is made such that when pulling out of the shelf from the refrigerator out of Gleitnocken comes into contact with the stop cam and thus a limitation of Extract or the pull-out movement of the shelf represents. To remove the shelf is raised, and the cams come to the side except Intervention. The removal of the shelf can thus not in one Movement can be achieved with the pulling out, but it Two separate movements (pulling and lifting) are necessary.

at The description of this invention will be in terms of directional indications like "top", "bottom", "front" and "back" of a usual Set up the refrigeration device, at the front of a door of the refrigerator and at the back their back wall located. Get information such as "left" and "right" in the manner of presentation chosen in the drawing.

Of the Slide cam is on one side of the shelf, which is a side wall facing the refrigerator is appropriate. Usually the Gleitnocken is molded onto the shelf or the shelf is provided with a lateral encapsulation, which the Gleitnocken contains. As a rule, the back of the shelf is also encapsulated, because on this back an upwardly projecting section is to be provided which ensures that the refrigerated goods located on the shelf not the rear wall of the refrigerator is too close and could freeze to it, so at least To provide three sides of the shelf with an encapsulation. This elevated the complexity hence the cost of the manufacturing process of each shelf.

Of the Present invention is based on the object, a refrigerator with extendable Shelf to create, where the aforementioned disadvantages are not exist and that can be produced easily and inexpensively.

These Task is with a refrigerator according to claim 1 solved. Advantageous developments of the invention are the subject of the dependent claims.

According to the invention is at a refrigeration device described above, the arrangement made such that on the shelf a hook is provided, which the at least one rib in the vertical direction - at least substantially - positively embrace can and if desired except Intervention with the at least one rib can be brought. Besides, they are the Gleitnocken and the hook in the back of the shelf arranged. Ie. it only needs the back be configured so that the hook and the sliding cam arranged thereon can be. This is true even if the shelf is both on its left as well as on its right side with a hook and a sliding cam should be provided. In the case of spraying these components must thus only the back of the shelf and not the two sides. Thus, on the one hand, the means for the attack when undressing of the shelf and on the other hand for the guaranteed by the hook Make sure the shelf is undressing with its back do not tilt upwards from the rib, together at the back of the Another advantage is that that such a configuration can also be used if the shelf completely encapsulated or, for example, only his left side, right side and back side are overmoulded. This is an increased flexibility in the Design of the edges of the shelf.

There ensured by the hook that the shelf when pulling out does not tilt unintentionally, does not need any additional, provided above the rib on the respective side wall of the refrigerator to become the shelf not only from below, but also from up support. Such an additional rib would be otherwise to provide for all refrigeration appliances, at the accidental tilting of the shelf when pulling out not by a hook or similar guaranteed is.

According to one preferred embodiment of Invention, the arrangement is such that the hook through a Tilting movement of the front of the shelf up - and so against the effect of gravity, if appropriate, on it Refrigerated goods - out of engagement can be brought with the rib. Thus, the shelf when pulling out Do not tip away unintentionally, but must by a user be raised deliberately to be completely removed from the refrigerator to be able to.

Preferably the sliding cam and the hook are integrated in a bar, the at the back of the Shelf is appropriate. This allows sliding cams and hooks, even if they are both on the left and on the right Side of the shelf should be attached as a single Piece on attached to the shelf, for example, injected, be. there it is preferred if the strip also has an upwardly projecting one Includes a section that can reliably prevent refrigerated goods stored on the shelf too close to the rear wall of the Refrigeration device arrives, which depending on the execution of the refrigerator by one of these adjacently mounted refrigeration device particularly cold is.

A Particularly simple arrangement results when the stop cam is formed as a projection, which from the top of the rib to protrudes below, and the Gleitnocken is formed as a projection, the from the bottom of the shelf protrudes down.

It may be advantageous if the hook relative to the slide cam to the rear is offset. This is the hook as far as possible moved the field of view of a viewer.

It is advantageous if the hook has a portion of the Shelf protrudes downwards and thus the rib is well in vertical Can embrace direction. It is also beneficial if this Section also protrudes to the rear, so that the point of application of the force, when pulling out of the shelf from the refrigerator, if necessary, in vertical Direction exercised will, if possible is far behind.

Around the shelf after the maximum possible Pulling out of the refrigerator in the state in which the slide cam in abutment against the stop cam has come to be able to pull out well, it is advantageous if the rib in this area - so in the area of the stop cam - on its bottom has a section which recedes upward, So a lower height having. This can be for example in the form of a gradation or Flattening be realized.

One particularly simple complete Removing the shelf from the refrigerator is possible if the rib in the area of the stop cam - so on its underside - one in terms of its height tapering from the back to the front first section, which thus forms an oblique surface on its underside, d. H. the rib has the smallest height at its foremost end and becomes backwards in the course of the inclined surface to ever higher. The arrangement is made such that the sliding cam of the shelf, in the course of pulling out of the shelf in contact with the stop cam the rib has passed over lifted up the stop cam and over this brought outwards in the vertical and horizontal direction Can be after the front end of the extracted shelf was pivoted upwards and thus the hook in this pivoting process moved in the area of the inclined surface and thus created enough "air" was that the sliding cam over the Stop cam can be lifted away. This way you can the shelf by means of a flowing and only aware of a user to be made to move up-swing the front of the shelf and lifting the back of the shelf with the slide cam over the stop cam away accomplished become.

It is advantageous if the rib - viewed from the front - no rectangular or square cross-section, but of seen further down into the cold room. Ie. in other words, that at the bottom of the rib in terms of its width is formed from top to bottom tapering second section, which forms a second inclined surface on its underside. The bottom the hook is accordingly designed to be there has an engagement portion, whose upper side substantially is parallel to the second inclined surface.

The stability the support of the shelf in the course of pulling out of the refrigerator can be improved when one is horizontally spaced from the first rib, continue at the door the refrigeration device located second rib is provided on the side wall on which the shelf rests. For this, the top of the second rib must be substantially are aligned with the top of the first rib. Between the first and the second rib is enough space that the "unthreaded" hook in this space can be moved up to the shelf to be moved up after its extraction and up-pivoting can complete the shelf from the fridge to be able to remove.

It it is preferred that the shelf and also the respective design or contouring of the respective side walls with regard to the sliding cams, stop cams and hook symmetrical to a center plane parallel to the side walls of the refrigeration device are. Ie. in other words, that the particular shelf at his back on both sides in each case the same design, which makes it better and more stable and is supported on the respective ribs.

A particularly simple design and handling results from that the rib on each upper side has a sliding surface on which the underside the Gleitnockens can be slidably moved.

According to one encompasses alternative embodiment the hook does not completely fill the rib in the vertical direction and lies with a hook at the bottom the rib, but engages from the side - ie horizontally - in the Rib. For this, the rib points horizontally from the front rearward extending section in which one is horizontal is provided from front to rear extending groove. In the area the underside of the Gleitnockens the hook is arranged and attacks as projecting in the horizontal direction of the Gleitnocken projection in the horizontal direction into the groove. Thus, the hook and the Gleitnocken formed as a single piece. In other In words, the bottom of this single piece forms the slide cam that opens rests on the rib and glides on it, and at the same time forms this Bottom also the hook, which engages in the groove of the rib. in this connection is natural important that the groove in the vertical direction substantially closed so that the hook does not move up can. Only in the region of the stop cam, the groove after one open top opening on, through which the hook can be moved upwards. This opening is in this case, so that the hook only by means of a pivoting movement the front of the shelf moved up out of this can be and not by, for example, a pivoting movement of the Shelf down (which could otherwise be unintentional). For this are at the top of the opening a corresponding projection and a corresponding bevel provided the only one removal of the hook from the opening through the above allow described pivoting movement.

It is advantageous if the sliding cam and the hook made of PU (polyurethane), PE (polyethylene), PET (polyethylene terephthalate) and / or POM (polyoxymethylene) are made, in particular the attachment by injection molding is preferred to the shelf.

In In practice, it has proved beneficial proven when the shelf designed as a continuous storage area is, which is preferably formed of glass or polyacrylic.

Further Advantages, features and peculiarities result from the following detailed Description of various embodiments the refrigeration device according to the invention. Show it:

5a - 5c various stages in the extraction of the shelf or the hook from the rib;

6 one of the 3a similar representation of a second embodiment of the refrigerator according to the invention;

7 one of the 5a similar representation of a third embodiment of the invention;

8th one of the 4 similar representation of a fourth embodiment of the refrigerator according to the invention; and

9 the fourth embodiment of the refrigerator according to the invention in side view.

In the 1 and 2 is a perspective view of the side wall 11 a refrigeration device according to the invention 10 with a shelf 30 shown. To support and guide the shelf 30 serve two ribs 13 and 19 , the exact configuration will be described later in detail. To the shelf in different height positions in the refrigerator of the refrigerator 10 to be able to attach are several of these ribs 13 and 19 arranged one above the other, with the sake of clarity in 1 only two pairs of these ribs 13 and 19 are shown. It goes without saying that both in this and in all embodiments described below, the right side wall 11 the refrigeration device according to the invention 10 as well as the right side of the shelf located there 30 analog or symmetrical to a perpendicular center plane of the refrigerator 10 can be configured to on the one hand a uniform design of the refrigerator 12 to achieve the refrigeration device and on the other hand, the leadership and the support of the shelf 30 to make it as optimal as possible.

At the back 31 of the shelf 30 is a bar 33 sprayed a section 34 comprises, which projects substantially vertically upwards. this section 34 represents a stop for refrigerated goods, so that this on the shelf 30 not too far to the rear or too close to the rear wall of the refrigerator 10 can get. The bar 33 also includes a hook on its underside 37 , one of the bar 33 from the downwardly projecting section 37a and one from the bottom of the section 37a projecting engagement section 38 that has with its top 39 the bottom of the first rib 13 is facing and optionally in contact with this first rib 13 arrives.

The 3a and 3b show the first embodiment from the side, wherein the (not shown) side wall of the refrigerator is located on the side facing the viewer of the drawing plane. The bar 33 with the upwardly projecting section 34 as well as the hook 37 are here on the right side of the drawing. At the bottom of the back 31 of the shelf 30 encompassing bar 33 is a sliding cam 35 molded, its bottom 36 (see. 5b ) on top of the first rib 13 which is a sliding surface 13b forms, rests and can slide on it. From the presentation of 3a and 3b it is apparent that the section 37a of the hook 37 not only protrudes down, but also to the rear, so the back of the refrigerator 10 out. This is the engaging portion 38 of the hook 37 as far as possible at the back of the first rib 13 , As shown in the diagram, the angle of the downwardly projecting portion 37a of the hook 37 to the vertical about 30 °, but is of course not limited thereto. Like also out 3a and 3b it can be seen, lies the top 39 of the engaging portion 38 not directly at the bottom of the first rib 13 but is located at a small distance thereof. However, once the shelf 30 at its back 31 can be raised to the top, the top 39 of the engaging portion 38 in abutment with the underside of the first rib 13 reach.

If the shelf 30 for example, by pulling on the front 32 from the fridge 12 is pulled out, the sliding cam passes 35 in abutment against a stop cam fourteen , at the front end of the rib 13 is provided. This stop the Gleitnockens 35 on the stop cam fourteen Make sure the shelf 30 can not be pulled too far. Like from the 3a and 3b can be seen, lies the shelf 30 not on top of the stop cam fourteen on, but only on the left here of the first rib 13 located second rib 19 and by means of the Gleitnockens 35 on the sliding surface 13b the first rib 13 ,

As shown in 4 protrudes the engagement section 38 of the hook 37 not exactly horizontal to the side wall 11 but its top 39 is formed inclined relative to the horizontal. Accordingly, the underside of the rib is also 13 not formed horizontally, but it has on its underside a second section 13a on, a second inclined surface 18 forms. Here are the inclined surface 18 and the top 39 of the engaging portion 38 in a "normal" position of the shelf arranged in the refrigerator compartment 30 roughly parallel to each other. Of course, the invention is not limited to this embodiment of the underside of the rib 13 as well as the top 39 of the engaging portion 38 limited. For example, the underside of the rib 13 also be much flatter inclined or even formed horizontally.

To the shelf 30 in the in 5a shown position completely out of the refrigerator of the refrigerator 10 must be able to remove the front end 32 of the shelf 30 as shown in 5b be pivoted upwards by about 15 °. Because on the one hand at the front end of the rib 13 at the bottom of an oblique surface 16 is provided, which is about the stop cam fourteen continues to the rear, and on the other hand, a certain game down to the top 39 of the engaging portion 38 is present, hinders the hook 37 not this pivoting process, but the top 39 of the engaging portion 38 comes approximately parallel to the inclined surface 16 lying, which has an angle of about 15 ° to the horizontal. Of course, this is only an example of the design of the inclined surface 16 to view, to which the present invention is not limited. After pivoting the shelf 30 this can still be lifted up a bit, until the Gleitnocken 35 above the stop cam fourteen located and the shelf 30 unhindered forward - ie in the horizontal direction - can be pulled out. This situation is in 5c shown.

The renewed insertion of the shelf 30 takes place in the reverse direction, namely by sliding the Gleitnockens 35 over the stop cam fourteen to the rear, with the front end 32 of the shelf is pivoted up, lowering the shelf 30 down and swing back the front end 32 of the shelf 30 down until the shelf 30 approximately in a horizontal position and additionally on the second rib 19 rests. After that, the shelf can 30 be pushed back into the refrigerator.

6 represents a second embodiment of the refrigerator according to the invention. In this embodiment and in all subsequent Embodiments denote like reference numerals and like elements, unless otherwise specified. To avoid unnecessary repetition, only the differences from the first embodiment will be described. In this second embodiment is not a separate second rib 19 provided, but the first (and therefore only) rib 13 '' is over the stop cam fourteen extended forward. The "unthreading" of the shelf 30 is done in a similar manner as in the first embodiment. After the sliding cam 35 over the stop cam fourteen has been transported outwards, while the engaging portion 38 along the inclined surface 16 may have moved, the shelf 30 be completely pulled out of the refrigerator. This is possible because of the rib 13 '' in the area in front of the stop cam fourteen has a lower height than the distance between the underside of the Gleitnockens 35 and the top 39 of the engaging portion 38 equivalent. However, the shelf can be 30 only by further pulling out over the front part of the rib 13 '' Be removed from the refrigerator, while it is also possible in the first embodiment, the shelf 30 with its rear end after passing the hook 37 on the stop cam fourteen to raise even further until the hook 37 above the front rib 19 can be moved past this out of the refrigerator of the refrigerator.

7 shows a third embodiment of the refrigerator according to the invention, which is in the design of the front portion of the rib 13 different from the first embodiment. In the third embodiment, at the front end of the rib 13 no oblique surface provided, but the underside of the rib 13 is as an upwardly receding section 17 educated. In this front section 17 So it's a step at the bottom of the rib 13 educated. Also by this stage is the swinging operation of the front end described in detail in connection with the first embodiment 32 of the shelf 30 possible to the shelf 30 completely removed from the refrigerator.

In 8th a fourth embodiment of the invention is shown. This fourth embodiment differs from the first embodiment in the design of the rib 13 ' and the sliding cam 35 ' as well as the hook 37 ' , The rib 13 ' has a section 13c on, which extends horizontally from back to front and in which a groove extending from back to front 13d is provided. This groove 13d is in the horizontal direction, ie from the side (in 8th from the right). As shown in 8th lies the underside of the Gleitnockens 35 ' on the bottom of the groove 13d on and slides on it. In the lower part of the slide cam 35 ' is a head start 37 ' off, in the groove 13d protrudes and acts as a hook. The projection or hook 37 ' can not be moved upwards as it passes through the top of the groove 13d is prevented from doing so. It should be noted that here the Gleitnocken 35 ' on the one hand and the hook 37 ' on the other hand are formed as a single part.

The groove 13d is substantially closed in the vertical direction. "Substantially closed in vertical direction" here means that the groove 13d over most of its length is not open at the top, but only in the area of the stop cam 14 ' has an upwardly open opening. This opening is dimensioned so that the slide cam 35 ' with the hook 37 ' only by a rotational movement, which by corresponding pivoting the front end 32 of the shelf 30 is effected, is movable out of this opening. This can be done as shown in 9 For example, be effected by the front end of this opening by a corresponding projection 13e the stop cam 14 ' is limited, while the rear end of the opening by a bevel 13f is extended.

All embodiments The present invention is characterized in that the extraction, the stop and the removal of the shelf by appropriate Design of Gleitcockens, the hook, the stop cam and the rib can be carried out very easily and not prone to failure.

It It should be noted that with reference to individual embodiments described features of the invention, such as the type and design of stop and slide cams, hooks and rib, also in other embodiments can be present except if otherwise stated or for technical reasons forbids itself.
