On the underside of the cabinet 1 a tapered pedestal 8th exhibit. In the present embodiment, the cabinet 1 a sink cabinet with a in his top or work surface 2 sunken sink 9 that has a drain 11 has, from which a drain line 12 with a siphon 13 extends, preferably the rear wall 4 interspersed in a penetration hole.

The wardrobe interior 14 is through a closet door 15 , In particular, a flap door, accessible, which is preferably located at the front and through at the bottom of the door opening 16 arranged hinges 17 at the Cabinet 1 is articulated. At the upper edge of the opening is the door 15 by a closure with a locking mechanism 18 and a cooperating latch 19 locked in its closed position, wherein the locking mechanism 18 sunk at the top of the door opening and the latch 19 on the inside of the door 15 is attached. It is such a locking mechanism 18 that the tie 19 after a first push of the door 15 locked in its closed position and after a second push of the door 15 releases again. Such locking mechanisms 18 are known per se, so that it needs no further description.

Between the cupboard 1 and the door 15 is one in its entirety with 21 designated device for limiting the opening movement of the door 15 effective, which has the following elements:
A variable-length limit rod 22 , which at their one, here outer end by a first joint 23 with a first attachment piece 24 pivotally connected to the door 15 can be fastened and this at least a first fastener 25 has, for. B. in the form of at least one screw hole through which it by screws on the door 15 is fastened, especially on the inside.

A swivel part 26 passing through a second joint 27 with the other, here inside, end of the perimeter bar 22 is connected and through a third joint 28 swiveling with a base part 29 connected to the cabinet 1 is fastened, here on a side wall 5 . 6 , For this purpose, the base part 29 one or more second fasteners 31 on, z. B. one or more mounting holes through which it can be fastened by means of screws.

The device 21 allows opening of the door 15 in two stages. While 1 the door 15 in its closed position, shows 2 the door 15 in their first opening stage and 3 the door 15 in its second opening stage. The degree of opening between the first and second opening stages is determined by the distance between the second hinge 27 and the third joint 28 certainly. How out 2 and 3 can be clearly seen, is the arrangement and attachment of the base part 29 at the Cabinet 1 such that in the first opening stage according to 2 the second joint 27 on the door 15 opposite side of the third joint 28 is arranged while the second joint 27 in the second opening stage according to 3 yourself on the door 15 facing side of the third joint 28 located. In both Schwenkendstellungen is the pivoting part 26 through a first stop pair 33 . 34 and a second stop pair 35 . 36 limited. The first stop pair 33 . 34 limits the ejection movement of the door in the first opening stage, see 2 , The second stop pair 35 . 36 limits the ejection movement in the second opening stage, see 3 , Between these two stop positions leads the second joint 27 a above the third joint 28 extending arc movement. In the first opening stage is the second joint 27 in or behind the inner crank dead center T1 of the pivoting part 26 , which in its entirety with 37 designated hinge mechanism a more extensive opening movement of the door 15 locks. In the second opening stage is the second joint 27 in or before the outer crank dead center T2 of the pivoting part 26 ,

Such a blocking function can be both when moving the door 15 from their first opening stage in their second opening stage and vice versa cancel that the limiting rod 22 in the area of the second joint 27 when moving the door accordingly 15 in the sense of the arrow 38 is lifted, creating the second joint 27 in each case when switching off the blocking function is performed on its arcuate trajectory B1. This lifting can be carried out manually handling friendly. Preferably, the second joint is located 27 in the second opening stage in a position before the outer dead center T2, in which the closing movement of the door 15 without the above-described lifting of the limiting rod 22 can be done because the second joint 27 pivots automatically in the arcuate path B2 due to the lateral distance from the dead center T2. Such a position of the second joint 27 is in 3 shown. Here is the second joint 27 in the second opening stage above the outer dead center T2, which is located on the indicated dead center line T, which is the first joint 23 and the third joint 28 cuts.

The base part 29 and the swivel part 26 can by boards, z. Example of metal, be formed so that they the cabinet interior due to their narrow design 14 hardly affect. The third joint 28 may be formed by a hinge pin which is connected to one of the two joint parts, for. B. on the base part 29 is fixed, wherein the other hinge part, here the pivoting part 26 , Has a hinge hole with which it sits on the hinge pin with clearance and is secured against axial removal. The swivel part 26 may be in the form of a flat lever, with the associated stops 33 . 35 may be formed by laterally oppositely arranged step surfaces. The associated stops 34 . 36 at the base part 29 can by a common stopper part 37 be formed, the z. B. in the form of a pin from the base part 29 in the range of movement of the stops 33 . 35 projects.

The limit bar 22 is variable in length and biased by the force of a manually push-spring in its extended position. It may be a so-called. Telescope rod with two telescopic rod parts, which are coaxially nested and guided together. The limit bar 22 is preferably formed by a so-called. Gas spring, which is biased by a built-in spring in its extended position, with their rate of stretching movement is slowed down, as it is known per se, for. B. at the opening movement speed limiting gas springs on hood doors of vehicles.

On the inside of the door 15 is a container 41 , in particular for waste, releasably secured, z. B. hung from above. It can be z. B. a basket-shaped container 41 act.

The following is a use operation of the cabinet 1 or his door 15 described.

The locking mechanism 18 for the door 15 can be achieved by manually exerting pressure on the outside of the door 15 in the sense of the arrow 42 in 1 to solve. After completion of this pressure, the delimited during the previous closing operation limiting bar expands 22 and she moves the door 15 braked in the first opening stage according to 2 in which the limit bar 22 is in its maximum stretched position. Due to the relatively small opening path, the operator does not need to wait long for the door 15 has reached the first opening stage, and the operator can waste in this position through the existing opening slot in the container 41 interject. A subsequent manual closing operation can also be done with little handling and effort, since the closing path is relatively small.

For emptying or replacing the container 41 it requires the next larger second opening stage according to 3 in which the door opening is so large that the container 41 can be emptied or exchanged in a way that is easy to handle. To move the door 15 from her first opening stage ( 1 ) into the second opening stage ( 2 ) requires unlocking the by the pivoting part 26 and the perimeter bar 22 formed toggle joint 43 What in the present embodiment by a in the direction of the arrow 38 upward manual force on the perimeter bar 22 takes place at which the second joint 27 upwards and at the same time on an arcuate trajectory to the door 15 is moved, until it by the stop action of the second stop pair 35 . 36 is limited in its opening movement, see 3 , The closing of the door 15 from the second opening stage also takes place by a manual pressure exercise in the direction of the arrow 42 , where the toggle joint 43 automatically in its first joint position according to 2 swings. At the further manual Closing and latching the door 15 becomes the limit bar 22 pushed together and curious.

The device 21 for limiting the opening movement of the door 15 or flap is also functional when reversed between cabinet 1 and door 15 is arranged, so with her joint 23 at the Cabinet 1 and with the swivel part 26 at the door 15 ,
