Definitions

  • the present invention relates to a refrigerator with a refrigerator in which a refrigerated goods with the help of telescopic extensions is displaced
  • a refrigerated goods with the help of telescopic extensions is displaced
  • telescopic extensions for sliding suspension of refrigerated goods carriers, which may be baskets, plates or the like, in a refrigerator is well known
  • Such a telescopic extension generally comprises two intermeshing rails, which are displaceable relative to one another in their longitudinal direction, in each case by unrolling a roller fastened to a first rail on the other rail.
  • both must be supported against each other at at least two points spaced apart in their longitudinal direction.
  • the distance between these points is the lower, the farther the rails are pulled apart, so that the more the stability of the telescopic rail suspension decreases the more, the farther a refrigerated goods suspended from them is pulled out of the refrigerator of the refrigerator.
  • the freedom of movement of the rails is therefore generally much smaller than their length. Therefore, it is not possible to make the freedom of movement of a refrigerated goods carrier so great that it can be completely pulled out of the refrigerator with a simple, constructed of two rails telescopic extension.
  • telescopic extensions are needed with at least three mutually movable rails. These are significantly more expensive than those with two rails. It is therefore not economical for a manufacturer who wants to offer refrigeration appliances in a wide range of prices and equipment to consistently use telescopic extensions with three rails. However, if the manufacturer's model range includes both two and three or more rails, the problem arises that the different types of telescopic extensions differ in their space requirement.
  • the generic patent US 2,318,363 shows a refrigerator comprising a pull-out drawer.
  • EP 1 621 838 A2 and EP 1 617 160 A1 which are state of the art according to Art. 54 (3) EPC, each show a refrigerator comprising a refrigerator with an extendable drawer.
  • the drawer comprises a frame on which a basket is arranged. At a bottom of the frame, a guide rail of a telescopic extension is attached.
  • Object of the present invention is to minimize the number of different parts required for the production of different refrigerator models, both those with a fully removable refrigerated goods carrier as well as those with a partially extractable.
  • the object is achieved by ein.Kälte réelle with a refrigerator in which a first refrigerated goods with the help of two telescopic extensions is displaceable, in which the refrigerated goods is supported on each telescopic extension using at least one adapter and adegutieri supporting contact surface of the adapter on the Height of the telescopic extensions is.
  • the contact surface is placed higher than the telescopic extensions, it can also be positioned in the width direction of the refrigerator housing largely free and above all independent of the width of the telescopic extensions used, which allows the use of uniform refrigerated goods in conjunction with different widths telescopic extensions.
  • a maximum width of the refrigerated goods carrier and consequently a good space utilization are achieved when the contact surfaces of the adapter on both sides of the refrigerated goods are spaced as far as possible, especially if they are at least partially perpendicular extend over the telescopic extensions to which the respective adapter are attached.
  • the contact surface can also come to rest over a gap between the telescopic extension and the refrigerated goods container.
  • the width of this gap is preferably at least as large as that of the narrow telescopic extension itself, so that when needed in the space another Telescopic extension of the same type in series with the existing can be mounted to increase the freedom of movement of the refrigerated goods.
  • the adapter is preferably angular, with a laterally attached to the associated telescopic extension vertical leg and a contact surface having horizontal leg.
  • the horizontal leg can rest for better stability because of directly on a top of the telescopic extension.
  • the adapters are preferably provided with latching elements for latching to a respective complementary latching element of the refrigerated goods carrier.
  • the adapters each have a front and a rear locking element, wherein the rear with the complementary locking element of the first refrigerated goods by a movement substantially parallel to the displacement direction of the firstdegutologis and the front with the complementary locking element of the firstdegutologis by a movement can be latched substantially perpendicular to the displacement direction of the first refrigerated goods carrier.
  • the front locking element prevents a disengagement, if only pulled on the refrigerated goods in the horizontal direction to pull it out of the refrigerator.
  • the rear locking element of the adapter can expediently be designed as an undercut rigid head and the complementary latching element of the refrigerated goods carrier as an open edge in the direction of displacement slot.
  • the front latching element is preferably a head which is flexibly deformable in each case during engagement and disengagement of the complementary latching element.
  • This head can be provided with a flexible in the direction of displacement flank, which holds in the latched state, the complementary locking element of the refrigerated goods carrier against a stop, so as to keep the refrigerated goods without clearance on the telescopic extension.
  • the complementary latching element of the refrigerated goods carrier is a hole into which the head engages, the stop may be formed by an edge facing away from said flexible flank of the head.
  • the front and the rear locking element are each formed separately from each other on a front or a rear adapter of each telescopic extension.
  • This bipartite makes it possible to use the same adapter both on a right and on a left telescopic extension or on telescopic extensions of different lengths.
  • front and rear adapters each have a plane of symmetry perpendicular to the direction of displacement of the refrigerated goods carrier, so that the two mounted on the right or left telescopic extension front adapter or the two mounted on right and left telescopic extension rear adapter each other like mirror images lie opposite.
  • the freedom of movement of two mutually movable rails of each telescopic extension is preferably limited to less than two-thirds of its length. Although a greater freedom of movement would in principle be achieved, but would then occur in the maximum extended state between the rails torques require a high degree of strength of the rails and thus cause a cost-increasing significant cost of materials. Such a great freedom of movement of the individual telescopic extension is not required in the context of the present invention, because in order to achieve greater freedom of movement, preferably two telescopic extensions connected in series are used.
  • Refrigerated goods carriers held via individual telescopic extensions and refrigerated goods carriers held in series via telescopic extensions can be combined in one and the same refrigerator.
  • the shape and arrangement of the complementary locking elements of the two refrigerated goods carriers are preferably the same in such a case. This is z. B. possible to mount at least one of the two refrigerated goods in the place of the other.
  • each refrigerated goods carrier in several parts, from a base body and two support parts attached to the base body, wherein the complementary locking elements are formed on the support parts.
  • each telescopic extension is preferably guided relative to one another with the aid of linear ball bearings.
  • Fig. 1 shows a perspective view of a refrigerator with a body 1 and a door 2.
  • a refrigerator 3 inside the device are two refrigerated goods 4, 5 in the form of pull-out boxes exemplified.
  • the pull-out boxes 4, 5 are held displaceable in the figure not visible, suspended on the side walls of the body 1 telescopic extensions.
