Description

Refrigerating appliance with a door rack and a slide guide

The invention relates to a refrigeration appliance, in particular domestic refrigeration appliance, comprising a door with a door inside, on which a door rack is guided adjustable in height, and a locking device by which the door rack can be locked in its altitude.

EP 2 108 907 A1 describes a refrigeration appliance, in particular domestic refrigeration appliance, comprising a housing with an interior therein for receiving refrigerated goods, a door with an inner wall and an outer wall for opening and closing the interior with at least one door compartment wherein the door has at least one fastening rail for holding the door compartment on its inner wall. The height-adjustable door compartment is held on a wave profile, in which engages from the side of a locking element for locking the height-adjustable door compartment. The locking element is pressed by a spring in the wave profile. To adjust the height of the height-adjustable door compartment a release button is provided, with which the engagement between locking element and wave profile can be solved.

The invention has for its object to simplify the height adjustment and locking a door compartment on a door inside the refrigerator in a refrigeration appliance, in particular domestic refrigeration appliance.

A refrigeration appliance is understood in particular to be a household refrigeration appliance, that is to say a refrigeration appliance used for household purposes or possibly even in the gastronomy sector, and in particular for storing food and / or beverages in household quantities at specific temperatures, such as, for example, a refrigerator, a freezer , a fridge-freezer or a wine fridge.

The object is achieved by a refrigeration device, in particular domestic refrigeration appliance, comprising a door with a door inside, on which a door rack is guided adjustable in height, and a locking device by which the door rack can be locked in its altitude, in which provided on the inside of the door a slotted guide is that has at least one groove in the at least one with the door rack connected sliding block engages and the at least one first groove portion for height-adjustable guidance of the door compartment, as well as at least one latching device forming second groove portion, in which engages the sliding block connected to the door rack for locking the door compartment at a predetermined height.

A backdrop can be understood quite generally as a certain type of transmission element for power transmission (link guide). The link or the guide slot, for example, a groove, possibly also a slot or a web, in which a sliding block is positively driven on opposite sides to a movement of the sliding block along the backdrop in a movement of the associated with the sliding block component, here a door rack, implement. Instead of a conversion into a movement, an implementation in a particular rigid storage and / or fixation can take place. The transfer function of the slide guide is determined by the course of the slot, web or groove and is in the inventively provided functional limits of height-adjustable guiding on the one hand and the locking of the door compartment at a predetermined height on the other hand generally freely selectable. In the following, various concrete embodiments of the invention are described.

By means of the slotted guide according to the invention, the door rack can be used without separate movable locking mechanisms, in a simple manner höhenverstellt and locked or solved for Höhenverstellen. The slide guide according to the invention allows unlocking and locking the door compartment alone due to a change in the position, in particular a pivoting of the door compartment by hand. In the case of a rigid design of the grooves and sliding blocks, a reliably functioning, less interference-prone locking device is created.

The leadership of the backdrop can follow such a course by the release of the door compartment from the hand of a user of the refrigerator, the door rack pivots alone due to gravity in such a situation in which at least one sliding block catches in a branch bag of the scenery, causing the Door racks are locked automatically in an altitude. The automatic pivoting due to gravity can take place around the axis of one of the other sliding blocks.

As a sliding block that part or parts understood that are connected to the door racks and engages in the at least one groove of the slotted guide. It must not be necessary to provide the grooves on the inside of the door grooves and the sliding blocks on the door rack, but it may possibly also the sliding blocks as, for example, recessed groove bases formed on the door rack and the guides on the inside of the door to be formed as projecting webs. A first groove portion and a second groove portion may be formed by portions of the same groove.

The slotted guide may have two mutually separated grooves, of which one groove has the first groove portion and the other groove has a plurality of second groove portions. By the first groove portion and the second groove portion may be made a functional separation of height-adjustable guide and locking the door compartment at a predetermined height.

One of the slotted guides i. in particular, the first groove portion may have a straight vertical course. The slide guide, together with the corresponding guide element, i. prevent the sliding blocks of the door racks tilting the door compartment. The other slotted guide i. In particular, the second groove section may have a plurality of end-to-end groove branches extending in particular obliquely downward, in the direction of the inner wall. These ending groove branches, also referred to as branch pockets, act like notches which engage the corresponding guide member, i. hold the respective sliding block at a predetermined height. The door racks can in this way by pivoting with other guide elements from the latch cuts i. Branch pockets loosened the slide guides, adjusted in height and used with the corresponding guide elements in other notches again. Since this is only a pivoting about a relatively small angle, the door rack before the height adjustment, in particular, does not have to be emptied.

In all embodiments according to the invention, the first groove section can be located vertically. kaier direction over a predetermined Gesamtverstellhöhe extend and have the second groove portion in a plurality of predetermined for locking the door compartment predetermined heights ending branch pockets. An upper end and a lower end of the first Nutenabschnitts can limit the Gesamtverstellhöhe the door compartment. The door stop can then not be moved further up if its sliding block is present at the upper end of the first Nutenabschnitts and not further moved down when its sliding block is present at the lower end of the first Nutenabschnitts. The second groove portion of the slotted guide may have a plurality of stacked, each extending downwardly and in the direction of the inner wall of the door extending branch pockets which are interconnected via particular arcuate Verbindungsnutabschnitte. In other words, the slotted guide may be provided with the plurality of obliquely downward, extending in the direction of the inner wall and ending branches. The branches can be formed from stacked and interconnected sections. The sections may have a curved course. By this measure it is achieved that the guide elements, which are intended for the height fixation of the door compartment, do not have to be moved around corners and thus tend to tilt. Furthermore, this results in a backup, in the event that the door rack should be accidentally released after swinging. In this case, the door racks do not slip to the lower end of the slotted guides, but the guide elements responsible for the height fixation are automatically inserted into the next lower branch and safely picked up there.

The guide element for engagement with the slide guide, with a particular straight, vertically extending portion may near the upper edge of the side wall of the door compartment and the guide element for engagement with the guide slot, with the plurality of obliquely downwards, extending in the direction of the inner wall branches, be arranged near the lower edge of the side wall of the door compartment. As a result, the greatest possible distance of the guide elements of a page in the vertical direction guaranteed from each other. In particular, the force acting on the slotted guide with the straight, vertical area and the associated guide element is kept as small as possible. The stability of the arrangement can thus be increased if necessary.

The door racks can therefore have on opposite sides in each case a first sliding block, which engages the height-adjustable guide of the door compartment in the first groove portion and each having a second sliding block, which engages for locking the door compartment at a predetermined height in the second groove portion.

The first groove portion may be disposed closer to the inside of the door and the second groove portion further from the inside of the door, and the two sliding blocks may be arranged at diametrically opposite end portions of the opposite sides of the door compartment.

The slotted guide with the straight, vertically extending groove can be arranged closer to the inner wall of the door, as the groove with the plurality of obliquely downward, extending in the direction of the inner wall branches. The first sliding block may be arranged at an upper end portion of the door compartment and the second sliding block at a lower end portion of the door compartment.

In all embodiments according to the invention, the at least one first groove portion and / or the at least one second groove portion for insertion and removal of sliding blocks of the door compartment can be open-edged.

The edge-open groove sections thus have openings of the slotted guides. An insertion and removal of the door compartment can be done in this way easily from the front towards the inside of the door. It is thus possible, via the height-adjustable door racks, for example, to install another door racks, which does not have to be removed when removing or installing the height-adjustable door racks. In a variation of the embodiments of the invention, the at least one groove may be provided on a vertically extending guide rail which is connected to the inside of the door. The slide guide can be arranged on a side edge, which in particular runs perpendicular to the inside of the door, for example also on a spar of the door. If the slotted guide or the slotted guides are provided on at least one guide rail, then elaborate grooves can be omitted directly on the inside of the door. Conventionally, the door inner sides are made of plastic plates, for example by deep drawing. In the deep-drawing process, however, it is costly to produce, in particular, thin grooves in the plastic plate. According to the invention it is therefore advantageous to provide the slotted guide, in particular the grooves directly on a guide rail. The guide rails can be produced, for example, in a simple manner as a plastic injection molded part. In plastic injection molding, even narrow grooves can be made easier and more tightly tolerated.

There may be two guide rails, in particular provided with two mutually facing grooves, between which the door rack, in particular by means of at least two laterally arranged from the door compartment, pointing away from each other sliding blocks is mounted vertically adjustable. Each door racks can be held by two opposite guide rails. It can be provided, for example, left and right on the door, each over the height of the door continuous guide rails on which a plurality of door racks are held one above the other. However, it is also possible to provide two individual guide rails for each individual door rack. Thus, for example, for the storage of two door compartments on each other two left, and right two, so a total of four, guide rails may be attached to the door. In each case two superimposed guide rails can be arranged at a significant vertical distance from each other.

Depending on the embodiment, the slotted guides or the guide rails can optionally be provided on inner sides of bars of the door facing each other. The least one guide rail can be firmly connected to the spar. For attachment of the least one guide rail can serve spars, which are provided on the inside of the door. The separately manufactured guide rails can on be attached to the spars in different ways.

The guide elements i. the sliding blocks can be formed, for example, as a pin. A cylindrical shape of the pins allows the door rack to be easily pivoted. Also, the diameter of the pins are adapted to the clear width of the slide guides exactly. Even in arcuate sections of the slide guides so that a low-backlash guidance of the guide elements are possible. The guide element i. the sliding blocks or pegs can be integral with the

Be formed door rack. As a result, a cost-effective production can be carried out, in which in particular no additional assembly is required. The example, as an injection molded part together with the guide element. the sliding blocks or pegs manufactured door racks must be used only in the slotted guides on the inner wall of the door.

An exemplary embodiment of the invention is described with reference to FIGS. 1 to 3d. From the detailed description of this specific embodiment, there are also other general features and advantages of the present invention.

The door rack 1 shown in FIGS. 1 a to 1 d is initially shown in isolation. The door racks 1, in the illustrated embodiment, a container 2, which may be provided in the upper region with a rim reinforcement 3. A container interior space 7 is delimited by a container rear wall 8, two container side walls 9 and a front container front 10. At the container side walls 9, the edge reinforcement 3 can be provided in each case in the upper region. The door rack 1, in the embodiment shown on each container side wall 9 an upper sliding block 5 and a lower sliding block 6. On both side walls 9 below the edge reinforcement 3, in particular at a small distance from the container rear wall 8, a vertical reinforcing rib 4 can be provided. The reinforcing rib 4 can be flush with the edge reinforcement 3. The reinforcing rib 4 may have the lower sliding block 6 in its lower region. In Fig. 2a and Fig. 2b, the inner wall of the door 1 1 of the refrigerator 3 is shown. Near a side edges of the door 1 1 two spars 12 are mounted in the vertical direction. At their lower ends, the spars 12 are connected to each other by a connecting bar 13. The connecting rail 13 serves the stability and can additionally act as a support and support for a door racks 1. The spars 12 are designed to be continuous on their outer sides, so that a smooth, easy-to-maintain surface is created. At the mutually inclined inner sides of the spars 12, a rear slotted guide 14 and a front slotted guide 16 are provided.

The exemplary design according to the illustrated embodiment of the slide guides 14 and 16 is shown in Figs. 2a, and Fig. 3a to 3d. The rear slotted guide 14 has a first groove or a first groove section. The rear slotted guide 14 consists mainly of a straight channel, which opens into an upper opening 15. The opening 15 is accessible from the front of the spars 12.

Furthermore, the front slotted guide 16 is provided in the spars 12. The front slide guide 16 has a second groove or a second groove portion. This front slide guide 16 opens with an upper opening 17 at the front of the spars 12. The front slide guide 16 is composed in the illustrated embodiment of a plurality of arcuate Verbindungsnutabschnitte 18, each communicating with each other that obliquely downward branches 19 result. The rear slotted guide 14 is provided in each case for receiving the upper sliding block 5. The diameter of the upper sliding block 5 and the clear width of the rear slotted guide 14 are matched accordingly.

The lower sliding block 6 has a certain distance from the container rear wall 8 and cooperates with the front slide guide 16. In order to prevent that the upper sliding block 5 is accidentally inserted into the opening 17 of the front slide guide 16, the diameter of the upper sliding block 5 may be designed so that it does not fit into the opening 17. In the embodiment shown in the bars 12 are still provided additional mounting options 20 for not height-adjustable door racks. Of these mounting options 20, there are two above the slide guides 14 and 16 and one below this slide guides 14 and 16.

In Fig. 3 it is shown how the door rack 1 is mounted in the bars 12 of the door 1 1. The door rack 1 is held slightly inclined. First, the upper sliding blocks 5 are inserted into the openings 15 of the two rear slide guides 14. The door rack is now fully pressed in the direction of the inner wall of the door 1 1 until the upper sliding block 5 is in the vertical region of the rear slotted guide 14. The lower sliding block 6 is in this state at the front of the beam 12. Now, the door racks 1, as indicated in Fig. 3b, lowered so far that even the lower sliding block 6 can engage in the opening 17 of the front link guide 16. Now the door racks 1 is lowered so far that the lower sliding block 6 is located below the opening 17 and thus set within the slotted guide 16.

The door racks 1 can, as shown in Fig. 3c, in its lower part slightly pulled away from the inside of the door 1 1 and can be moved in this way to the desired position. In this position, which is shown in Fig. 3d, now the lower portion of the door compartment 1 is pressed against the inner wall of the door 1 1. The lower sliding block 6 is pressed in this way in one of the branch pockets 19 of the front guide slot 16. In this position, the door rack 1 is fixed and can not be changed in its height.

If the door rack 1 is now loaded, a torque acts around the lower sliding block 6. This torque is introduced from the upper sliding block 5 into the wall of the rear sliding guide 14. Since the two sliding blocks 5 and 6 lie almost on a vertical line, the moment which is exerted by the upper sliding block 5 on the boundary wall of the rear slide guide 14 is practically vertical. right to this. In this way, a resulting material-related elasticities Abkippwinkel the door compartment 1 can be kept very small at heavy loading. If the door racks 1 are to be adjusted in height, it only has to be pivoted away from the inner wall of the door 11 in its lower area by a small amount and pushed into the new position. In this new position, the underside of the door compartment 1 is again pressed against the inner wall of the door 1 1, so that the lower sliding block 6 are again 16 in one of the branch pockets 19 of the front Kulissenfüh-. The door rack 1 does not necessarily have to be unloaded for this process.
