Fig. 3:

1 in a side view.

1 and 2 show the hinge according to the invention Body fitting body 30 on which the articulated lever 40 and the toothed lock washer 70 are articulated. The articulated lever 40 is pivotable about the articulation points 54 and 64 in communication with the first lever 50 and the second lever 60.

The first lever 50 and the second lever 60 are each pivotable about the Articulation points 52 and 62 with the door fitting body 20 in connection. The Door fitting body 20 is screwed to the flap 10.

The second lever 60 has a U-shaped cross-sectional profile and takes in 1 the first lever 50, the Articulated lever 40 and the toothed disk 70 partially in the profile.

The articulated lever 40 is provided in two, the two articulated levers 40 in the view of FIG. 1 and FIG. 2 are aligned, so that only the front of the articulated lever 40 is visible.

The toothed disk 70 has the toothing 72, which with a toothing 82 of the Rotary damper 80 is engaged. The rotary damper 80 consists of a with the body fitting body 30 attached base body and a pinion rotatable relative to the base body, which in the view according to FIG. 1 and Fig. 2 is shown. The rotary damper 80 is designed with a freewheel, whereby it is achieved that only the rotational movement of the pinion of the Rotary damper 80 is damped when closing the hinge while the Opening movement is undamped due to the freewheel. This will ensures that the lid can be opened with little effort.

In its end region, the toothed disk 70 can be pivoted with the second lever 60 connected. In the area of the articulation point of the second lever 60 with the Toothed washer 70, the disk 74 is provided.

In the position shown in FIG. 1, the disk 74 exercises on the upper one End region of the piston 92 of the piston-cylinder unit 90 exerts a force that of the piston 92 in the completely in the piston-cylinder unit 90 held position is held.

The articulated levers 40 are connected to a spring 42, one end region of which is firmly connected to one of the articulated lever 40 and the other End region on the carcass fitting body 30 by means of the fastening element 36 is fixed. The spring 42 has a plurality of turns between the articulated levers 40 on. The movability of the articulated lever 40 is determined by the stop element 38 limited.

If the door 10 starts from the position shown in FIG. 1 in the position shown in FIG. 2 pivoted position shown, the second lever 60 experiences a by Articulated lever 40 and the toothed disk 70 defined pivoting movement. At the same time as the pivoting movement of the second lever 60, the flap becomes 10 around the articulation point 62 of the second lever 60 on the door fitting body 20 pivoted, as can be seen from Fig. 2. This overlaid Swivel movement is due to the fact that the distance between the Articulation points 52 and 54 of the first lever 50 is shorter than the distance between the pivot points 62 and 64 of the second lever. This additional Pivoting movement has the advantage that the flap 10 does not touch the interior of the container is aligned, but as can be seen from Fig. 2 from this Area is removed.

The opening movement of the flap 10 is supported by the spring 42 which is on the articulated lever 40 exerts a force acting in the opening movement. The spring 42 is tensioned during the closing process. The flap 10 from the Moved out of the closed position, this also leads to an extension of the Piston 92 from the piston-cylinder unit 90, whereby at least in this Another area of the closed position of the flap 10 and the hinge Support of the opening movement is generated.

During the opening movement of the flap 10, the toothing 72 becomes relative to the rotary damper 80 moves. The relative movement between teeth 72 and the toothing 82 causes the rotary damper 80 or its Pinion rotates during the movement and accordingly the movement of the flap 10 dampens during a closing process. Because of the free running of the Rotation damper 80, on the other hand, takes place when flap 10 is opened undamped so that an easy opening of the flap 10 is possible.

The flap 10 from the position shown in Fig. 2 in the closed position 1 pivoted back, takes place according to the above statements damping this movement by means of the rotary movement Rotation damper 80. Once the disc 74 with the end portion of the piston 92 comes into contact, which is the case before reaching the closed position, is in the further closing movement of the pistons 92 into the piston-cylinder unit 90 introduced so that the closing movement in this area in addition by the Piston-cylinder unit 90 is damped. The piston-cylinder unit 90 takes over the braking of the flap as a linear damper during closing 10 shortly before hitting the body, so as to make a quiet closing noise guarantee. While the linear damper only in the closed position leads to damping, the rotary damper 80 takes over the entire Closing the flap 10, the damping described.
