Dish rack

1. A dish rack comprising: a cassette configured to be attached to the underside of a cabinet or a shelf, wherein the cassette comprises a foldable wire shelf having at least two sections, wherein the wire shelf is configured to move between a first position and a second position, wherein:

in the first position, the wire shelf is folded and housed within the cassette and can be pulled out of and folded down from the cassette,

in the second position, the wire shelf is in a folded-down position and the cassette supports a rear edge of a first section of the wire shelf so that the first section hangs down at a first predetermined angle relative to said underside, and a second section of the wire shelf is rotatably connected to the first section at a front edge thereof and capable of being folded outwards from the first section so that the second section, in folded-out state, forms a second predetermined angle to a plane through the first section,

wherein the cassette at two parallel sides, along which sides the wire shelf can be moved, is equipped with two longitudinal guide rails on which a first wheel set arranged in front of the rear edge of the wire shelf is able to run.

2. The dish rack according to claim 1 , wherein the sides of the wire shelf, at its rear edge of the first section of the wire shelf, are provided with at least two profiled members along the direction of pulling of the wire shelf, and wherein said members have a backwardly directed extension in which an axle for rear wheels is journalled and wherein said rear wheels in a folded-down position of the wire shelf run against an upper surface of the cassette, and that an axle for said first wheel set is journalled in a front part of said members.

3. The dish rack according to claim 2 , wherein the tilt angle of the wire shelf downwards and forwards is determined by the relative position between the journal for the axle of said rear wheels and the journal for the axle of the first wheel set in said members.

4. The dish rack according to claim 3 , wherein the wire shelf, in a folded-down position, may be inserted into or pulled out of the cassette, whereby the weight of the wire shelf is absorbed by the first wheel set which in a downward direction loads and runs on the guide rails and by the rear wheels which in an upward direction load and run against the upper surface of the cassette.

5. The dish rack according to claim 4 , wherein the rear wheels, when the wire shelf is being pushed in at a rear end position for the wire shelf, pass a boss so that the wire shelf is kept by the boss in its uppermost position and wherein the rear wheels, when the wire shelf is being slightly pulled out, are released from the boss so that the wire shelf at the front edge of its first section falls down a short distance which is determined by a clearance between the rear wheels and the upper surface of the cassette.

6. The dish rack according to claim 5 , wherein a torque damper comprising a wheel with a few teeth is arranged adjacent the profiled member so that these teeth, when the wire shelf is being pulled out, make contact with an arm with corresponding teeth, whereby the movement of the wire shelf, while being folded downwards, is damped by the torque damper.

7. The dish rack according to claim 6 , wherein the first and second sections of the wire shelf are provided with parallel wires, essentially aligned with each other, which run in the direction of pulling of the wire shelf.

8. The dish rack according to claim 1 , wherein said guide rails comprise racks and wherein the wheels on said wheel set are integrated with toothed wheels which cooperate with and correspond to teeth on said racks.

9. The dish rack according to claim 1 , wherein a cable is fixed at the respective ends of an axle for the first wheel set and wherein said cable is arranged in an endless loop over sheaves arranged such that the wheels in the wheel set are forced to move synchronously, thus preventing oblique motion of the wire shelf when said shelf is being pulled out or pushed in.

10. The dish rack according to claim 1 , wherein said first predetermined angle is between 35 and 90 degrees, and wherein said second predetermined angle is in a range of 60 to 150 degrees.
