Definitions

• the present invention relates to a refrigerator, such as a refrigerator or freezer, and in particular to the problem of user-friendly division of the interior of such a refrigerator using one or more shelves.
• a height adjustability of such shelves is achieved in that when the inner container of such a refrigeration device is formed, a plurality of horizontal grooves are formed at different heights on the side walls of the inner container, into which the shelves can be inserted.
• Another disadvantage of this known solution is the practically lacking possibility of correcting the position of the shelves as needed when they are loaded. Often, especially when a user has to store large amounts of groceries in a refrigerator, the problem arises that it is only towards the end of the loading process, when space in the refrigerator becomes scarce, that the current positions of the shelves for accommodation become apparent of the existing refrigerated goods is not optimal, and that one of the existing compartments lacks storage height, while in an adjacent compartment there is height that cannot be used reasonably. In such a condition, pulling out a loaded shelf and reattaching it higher or lower is very difficult, if not impossible.
• a refrigeration device with the features of claim 1.
• the pivotability of the support arms here permits height adjustment of a shelf guided by the support arms, for the implementation of which it is not necessary to remove the shelf completely from the refrigeration device. If these support arms can be swiveled independently of one another, they enable various inclinations of the shelf.
• a pivotable support arm and a horizontally displaceable suspension are present on each edge of the shelf. By pivoting the support arm up and down, this allows the shelf to be adjusted between two differently inclined positions, the horizontally displaceable suspension defining an axis for the pivoting movement of the shelf.
• Such a construction enables z. B. the adjustment of the shelf between a horizontal and a downward to the front or to the door or to the rear or to the rear wall of the refrigerator.
• Such a sloping position of the shelf can e.g. be useful for lying storage of cans or bottles that always roll on the sloping shelf to the lower edge, where they can be easily removed.
• two pivotable support arms are provided on each side edge of the shelf, which are referred to as front and rear support arms.
• a shelf is capable of a horizontal upper rest position in which the second axis runs above the first axis of each support arm, a lower rest position in which the second axis below the first
• the axis of each support arm runs and one or two oblique rest positions, in which the second axes of the front and rear support arms are each at different heights.
• the variety of possible positions is thus increased compared to the first embodiment, and in particular a guided parallel displacement of the shelf between two horizontal positions is possible at different heights.
• At least three pivotable support arms are provided on each side edge of the shelf.
• Such a shelf is only adjustable between horizontal positions; a change from a horizontal to an oblique position is excluded by the third bracket. This configuration is therefore particularly suitable for the above-mentioned problem of height adjustment of the shelves when loaded.
• This variant has the advantage over the slope in the forward / backward direction that there is no risk of the refrigerated goods falling out, since it is always supported on the lower side edge by the side wall of the refrigerator housing.
• support arms can be connected to one another in pairs. This is again useful for the height adjustment of loaded shelves.
• a catch device for refrigerated goods is attached to a front and / or rear edge thereof, which prevents refrigerated goods from falling out when changing to the inclined position.
• the support arms can be designed in a simple manner as double-bent metal pins, with a first pin for engaging in an opening in the wall and a second pin for engaging in a recess in the shelf, and an intermediate section angled against the pin, connecting them.
• At least one device for locking such a support arm is desirable.
• This can be formed in a simple manner by an elastically displaceable tongue with a stop surface oriented transversely to the direction of displacement of the tongue, which - preferably in the relaxed state of the tongue - supports a side of the intermediate section facing the rear wall of the refrigerator.
• the recess provided thereon for receiving the second pin is open at the bottom. This makes it possible first to insert the support arms into the openings in the side walls and then to place the shelf on the second pins projecting from the side wall and to insert the second pins into the recesses from below.
• the cutouts and the pins are preferably dimensioned such that the pins are each clamped in the cutouts. This prevents the pins from falling out of the recesses when the plate is raised, instead of following the movement of the plate.
• Such a clamp seat can be implemented well on a plastic body which is separate from the shelf and preferably plug-connected to it. Further features and advantages of the invention result from the following description of exemplary embodiments with reference to the attached figures. Show it:

• FIG. 13 shows a modification of the shelf of FIG. 3.
• FIG. 1 illustrates the principle of the invention using a perspective view of a shelf 1 and part of a side wall 2 and a rear wall 3 of a refrigeration device.
• the walls 2, 3 of the refrigerator are constructed in a conventional manner from an inner container 4 thermoformed from plastic, an outer wall 5 and a layer of insulating foam 6 filling the space between the inner container 4 and the outer wall 5.
• the inner container 4 is flat in the region of the side wall 2 with Exception of blind holes 7, which are recessed during the drawing process, two of which can be seen cut open in the figure and two more each rotatably hold a first pin 10 of a support arm 8 for the shelf 1.
• Each support arm 8 comprises a first pin 10 which engages in a blind hole 7 of the side wall and which defines a first horizontal pivot axis A1 of the support arm.
• the support arms 8 can be produced in a simple manner by bending a round metal rod.
• the support arms 8 hang loosely down from the blind holes 7, the plane defined by the axes A1, A2 is vertical, and the shelf 1 is in a stable lower horizontal rest position.
• the support arms 8 pivot, and the shelf 1 is raised in accordance with the pivoting movement.
• the shelf By supporting and lifting the partially pulled out shelf by hand, it can be brought into a second rest position, in which the shelf is shown in dashed lines in the side view of FIG. 2.
• this second rest position which is also horizontal, the intermediate sections 12 of the support arms 8 extend essentially vertically upwards, with a slight inclination to the rear, towards the rear wall 3 of the housing.
• This inclination has the effect that the shelf 1 presses against the rear wall 3 with a force that corresponds to a small part of its mass and that of the refrigerated goods stored on it, and is thus stable even in the raised rest position.
• a device for locking the support arms 8 in the raised position is expediently provided, which is not shown in FIG. 2 and will be described in more detail later.
• each support arm 8 can continue to rotate both upwards and downwards. This makes it possible to set inclined positions of the shelf 1, as shown in FIG. 3 as a dash-dotted outline.
• the rear support arm 8 facing the rear wall 3 is lowered, while the front support arm 8 facing the door is raised.
• the shelf 1 is sloping towards the rear wall 3, and objects stored thereon tend to collect on the rear wall.
• the shelf 1 is here equipped with a collecting device 15 in the form of a plurality of vertical plates which, similar to the tines of a rake, extend from the front edge of the Prongs of a rake arranged to extend upwards from the front edge of the shelf 1 in order to hold round containers, such as bottles or cans, lying on the shelf formed here as a grid.
• a collecting device 15 in the form of a plurality of vertical plates which, similar to the tines of a rake, extend from the front edge of the Prongs of a rake arranged to extend upwards from the front edge of the shelf 1 in order to hold round containers, such as bottles or cans, lying on the shelf formed here as a grid.
• Such a configuration is useful, for example, for a refrigeration device that contains drinks for sale in bottles or cans: for loading a shelf, it can be placed in a horizontal or sloping position so that the containers can be conveniently inserted at the front edge. After the shelf has been fully loaded, it is brought into the sloping position shown in FIG. 4, so that each time a container is removed from the front edge of the shelf 1, a container behind it moves up and thus all containers are conveniently and quickly removed in sequence can be.
• FIG. 5 is a detailed view of a support arm 8 and its attachment to the shelf according to a first embodiment.
• the figure clearly shows the first pin 10 inserted into the blind hole 7 of the side wall 2, the second pin 11 connected to the shelf 1, the pivot axes A1, A2 defined by the pins and the intermediate section 12.
• the shelf 1 is essentially made of here a glass plate 17 is formed, which is enclosed in a circumferential profile 18 made of metal or a hard, resilient plastic.
• the profile 18 has two recesses on each side edge of the shelf 1, into which a connecting body 19 made of a tough, slightly deformable plastic material such as Delrin is inserted.
• FIG. 6 shows this connecting body 19 in a perspective view.
• a cover plate 20 which is rifflable on its upper side for better manageability, two legs 21 extend downward, which delimit between them a recess or groove 22 with a cross section adapted to the cross section of the second pin 11.
• the groove 22 is dimensioned such that the second pin 11 is clamped in it and can be rotated under friction, and it is narrowed slightly in its lower region, so that it is possible to insert the pin 11 into the groove 22 from below to press, but this can not fall out of the groove 22 when a user supports the shelf 1 with his hand in order to bring it into a raised rest position.
• the two legs 21 are each extended laterally by a tongue 23 which, together with the cover plate 20, holds the lateral edge of the shelf 1 clamped.
• a locking device is useful for securing the support arms 8 in the raised position.
• An example of such a locking device will now be described with reference to Figs. 7 and 8.
• Fig. 7 is a plan view of the front right corner of the shelf 1, on the underside of which such a locking device is arranged. On the left front corner of the shelf there is a locking device which is mirror-inverted to that shown in FIG. 7.
• Fig. 8 shows the corner and the locking device in side view.
• a short pin 25 extends downwards, which carries a tongue 26 which is flexible in the direction of the arrow P.
• the tongue 26 comprises, in its relaxed position shown in FIG. 7, a section 27 parallel to the lateral edge of the shelf 1, a section 28 extending obliquely outwards at an acute angle to the lateral edge, a locking section in FIG Form of a stop surface 29 perpendicular to the lateral edge and an actuating section 30.
• the stop surface 29 blocks rotation of the support arm 8 in the direction of the arrows P2 from FIG. 8 and thus holds the shelf 1 in the raised position.
• the support arms 8, which engage in opposite side walls 2 of the refrigerator housing, can be moved independently of one another, a user has the option, from the position of the shelf 1 shown in solid lines in FIG. 3, in which the intermediate sections 12 of the support arms 8 are oriented horizontally to further raise the support arms 8 on one side wall, in Fig. 9 the right side wall, while it allows them to return to their low position on the opposite side wall.
• the side, sloping position of the shelf 1 shown in front view in FIG. 9 is adjustable. This position also makes it possible to hold round objects, such as cans and bottles, on one side of the shelf 1 when they are stored horizontally.
• the higher-lying, free area of the shelf 1 can thus be continuously refilled, and if the lowest-lying container of a shelf is removed in each case, it is ensured that it is only the one who has been on the shelf for the longest time and who is probably the one is best chilled.
• a support arm of the right and an opposite support arm of the left side wall 2 are connected in one piece by a rod extending below the shelf 1, so that they can only be raised or lowered together.
• Simple support arms 8 and support arms 8 'connected in pairs can be supplied as accessories for optional use by a user with the refrigeration device according to the invention, so that each user can decide for himself whether he wants to use the inclination option or not.
• FIG. 11 shows an alternative type of connection of a support arm 8 to the shelf 1 on the basis of a cut parallel to the side edge thereof. If the material of the shelf 1 or of its frame profile 18 has a certain elasticity, it is possible to replace the connecting body 19 by the one-piece solution shown here, in which the legs 21, the groove 22 for receiving the second pin 11 limit, are integrally formed on the shelf 1 or frame 18.
• FIG. 12 A further modification of the suspension of the shelf 1 is shown in Fig. 12 in a side view analogous to the representation of Figs. 2 and 3 are shown.
• This modification differs from the embodiment of FIG. 2 only in the presence of a third support arm 8 on each side edge of the shelf 1. If the shelf 1 of FIG. 12 is raised here from the solid position, this third bracket prevents that starting from the intermediate position with horizontal intermediate sections 12 of the support arms 8, front and rear support arms in different before directions can be swiveled. It is thus impossible for a user to inadvertently set a position of the shelf 1 sloping forward or backward, in which there is a risk of the refrigerated goods falling out or falling over.
• This modification is therefore particularly well suited to adapting the heights of the shelves to current needs in a loaded refrigerator.
• a user can be given a simple choice as to whether he wants to use the inclination option or to lock it, by arranging the blind holes 7 on each side wall of the refrigerator housing at least three in a horizontal row and the shelves on each side edge with a corresponding number of recesses 22 are provided. Depending on whether the user equips two or more of these blind holes 7 and recesses 22 with support arms 8, he can determine whether the inclination is possible or not.
• FIG. 13 shows a perspective view of a simplified modification of the suspension of the shelf 1, in which there is only one pivotable support arm 8 on each side edge of the shelf 1.
• the second support arm is replaced by a rigid pin 31, which is horizontally displaceable in the direction of arrow P3 in an elongated hole 32 formed in the side wall of the refrigerator housing.
• the height of the area of the shelf carried by the pin 31 and facing the rear wall 3 of the refrigerator housing cannot be changed; only the front area can be adjusted between a horizontal and a sloping position or between two sloping positions in different directions.
