The cover plate comprises a lever which is pivotally mounted near a cabinet lid of the body on a side wall of the body. A first arm of the lever is pivotally attached to the second lid member near a hinge between the first lid member and the second lid member. A second arm, which is arranged approximately at right angles to the first arm, is pivotally connected to a compression spring element, which is supported against the body. In the closed position of the folding lid, the lever is acted upon by the compression spring element in such a way that a torque is generated, which acts on the folding lid in the direction of its closed position. When transferring the folding lid from the closed position in the direction of the open position, a dead center is exceeded, so that from an intermediate position of the folding lid it is acted upon by the compression spring element in the open position. In the open position of the folding lid an upper dead center is exceeded, so that the folding lid can not fall from the open position to the closed position. Due to the articulation of the first arm of the lever near the upper edge of the second lid member, ie near the hinge axis of the hinge between the first lid member and the second lid member, a handle for opening the folding lid is also to be arranged near the upper edge of the second lid member. This is necessary to be able to lift the lid from the carcass. In the open position of the folding lid, however, the handle is then in a very high position, so that it is difficult for people to reach. Furthermore, the folding flap is not held in any intermediate position of the folding lid between the open position and the closed position.

A folding lid mentioned above also shows the EP 1 055 381 A2 ,

In the swivel position of the actuator arm 13 , the closed position of the folding lid 8th corresponds, close the effective lever arm 17 between the first axis 10 and the second axis 12 and the effective lever arm 18 between the second axis 12 and the fourth axis 16 an angle directed to the body 19 a, which is slightly smaller than 180 °, so that the dead center position is not exceeded in this position. Thus can be by means of a handle 20 which is only slightly above the fourth axis 16 is arranged, the folding lid 8th from the body 1 take off and transfer to the open position.

In the pivot position of the actuator arm 13 ' , the open position of the folding lid 8th corresponds, close the effective lever arm 18 ' between the second axis 12 ' and the fourth axis 16 ' and the effective lever arm 21 ' between the fourth axis 16 ' and the third axis 15 one from the first cover element 9 ' directed angle 22 a slightly smaller than 180 °. In this position are the actuator arm 13 ' and the second lid member 11 ' arranged in an extended position to each other and have exceeded the top dead center of the rotary joint mechanism formed by the effective lever arms. Thus, the gravity of the folding lid causes 8th that the actuator arm 13 ' is acted upon in that pivot position, the open position of the folding lid 8th corresponds, so that the folding lid 8th can not move independently in the closed position. For this it is neces sary that on the handle 20 ' is pulled to the folding lid 8th to move out of the upper dead center.

To ensure that the first cover element 9 ' in the open position of the folding lid 8th not too far up over the cabinet lid 2 protrudes and to ensure that the second cover element 11 ' as close as possible to the first cover element 9 ' folded up, are the first axis 10 , the second axis 12 ( 12 ' ) and the fourth axis 16 ( 16 ' ) arranged to each other such that the effective lever arm 17 ( 17 ' ) between the first axis 10 and the second axis 12 ( 12 ' ) is longer than the effective lever arm 18 ( 18 ' ) between the second axis 12 ( 12 ' ) and the fourth axis 16 ( 16 ' ).

In addition, it should be ensured that the shelf 6 approximately at the level of an imaginary horizontally extending middle plane 23 of the body 1 can be attached. This is the third axis 15 above the middle level 23 arranged.

Because the handle 20 in the closed position of the folding lid 8th considered as far down the second cover element 11 should be provided so that frame cover elements can be used, which consist of a frame member which encloses a glass pane, must also be the fourth axis 16 as far down on the second cover element 11 be provided. For this purpose, it should be provided that the effective lever arm 17 between the first axis 10 and the second axis 12 is longer than the distance between the second axis 12 and a lower edge 52 the second cover element 11 which the first cover element 9 is arranged remotely.

In spite of the different lengths of the effective lever 17 . 18 visually a symmetrical division of the folding lid 8th to ensure the first cover element has a first panel 24 and the second lid member 11 a second aperture 25 on, both viewed in the closed position of the folding flap have the same height. At one to the corpus 1 directed inner surface 26 the lid element 9 is a hinge arm 27 attached, over a lower edge 28 the first aperture 24 protrudes down and at a lower end 29 around the second axis 12 hinged to one to the body 1 directed inner surface 46 the second aperture 25 is fixed. The distance between the lower edge 28 and the second axis 12 corresponds approximately to the distance of an upper edge 30 the second aperture 25 to the second axis 12 ,

At a standard height of the body of 720 mm is the third axis 15 preferably about 289 mm from the inner surface of the cabinet lid 2 and with the folding flap closed, about 78 mm from the inner surface 26 of the first lid member 9 away arranged. At a standard height of 600 mm, these values are about 223 mm from the cabinet lid 2 and 63 mm from the first cover element 9 ,

At both standard heights, at identical heights, the first aperture is 24 and the second aperture 25 the second axis 12 with the folding flap closed, about 52 mm from the lower edge 28 the first aperture 24 arranged offset down. The fourth axis 16 is 30 mm from the inner surface 46 of the second lid member and about 22 mm from the surface of the cabinet floor 4 away.

The lid plate 14 will be explained below using the 1 . 2 and 3 described together, wherein matching components are provided with the same reference numerals.

The actuator arm 13 is in a housing 31 the lid plate 14 around the third axis 15 pivotally mounted, the housing 31 firmly with the sidewall 3 of the body 1 connected is. The actuator arm 13 has a setting contour 32 on, in the form of a curve around the third axis 15 is shown.

In the case 31 is a lock slider 33 guided linearly displaceable. The lock slider 33 has a role 34 on that around a rotation axis 35 , which are parallel to the third axis 15 is arranged, rotatable on the lock slider 33 stored. With an outer peripheral surface is the role 34 in contact with the control contour 32 , feathers 50 apply the lock slider 33 and thus the role 34 against the control contour 32 , The spring means are based on the one hand against the lock slider 33 and on the other hand against a support bearing 36 from which linearly displaceable in the housing 31 is stored. The support bearing 36 is against a storage area 37 an abutment 38 supported, with the abutment 38 around a rotation axis 39 rotatable in the housing 31 is stored and where the storage area 37 a variable distance to the axis of rotation 39 of the abutment 38 so that the support bearing 36 at a variable distance to the third axis 15 in the case 31 is held. The storage area 37 is helical and has radial locking recesses into which a detent 41 of the support bearing 36 locks into place to prevent the abutment 38 unintentionally rotated.

The setting contour 32 the Stellarms 13 is formed such that the radial distance of the adjusting contour 32 to the third axis 15 in the contact area between the control slide 33 ie the role 34 , and the adjusting contour 32 via a pivoting path starting from a first pivoting position of the actuating arm 13 that the open position of the folding lid 8th corresponds, via an angular travel of the actuator arm 13 to an intermediate position of the actuator arm 13 representing a position of the folding lid 8th close to the closed position between the open position and the closed position corresponds, increases. This ensures that the actuator arm 13 is acted upon by the force over the largest Winkelweg, which is a moment to the upper position, the open position of the Faltdeckels 8th corresponds, generated. About the Winkelweg starting from the intermediate position to the pivot position, the closed position of the folding lid 8th corresponds, the control contour has a flattening over the course of which in the radial distance to the third axis 15 decreases. Thus, a torque is generated via this pivoting, which is the actuating arm 13 subjected to that pivotal position, which is the closed position of the folding lid 8th equivalent. The setting contour 32 is formed such that the torque generated in each pivotal position of the actuator arm 13 corresponds to that counter-moment, which by the weight of the folding lid 8th is generated in total, so that the folding lid 8th is held in any position between the open position and the intermediate position.

4 shows a length compensation element, which for pivotally mounting the actuator arm 13 on the second cover element 11 is provided. The length compensation element 43 comprises a base element 44 and a sliding element 45 , The basic element 44 is on the inner surface 46 the second aperture 25 in the area of the lower edge of the second panel 25 firmly mounted. The basic element 44 has a guide groove 47 on, in the closed position of the folding lid 8th considered vertically arranged and in which the sliding element 45 by means of a leadership approach 48 is guided linearly displaceable between a first and a second position. In the adjustment of the sliding element 45 is a spring 49 on the one hand at one end of the guide groove 47 against the base element 44 and on the other hand against the leadership approach 48 of the sliding element 45 supported, so that the sliding element 45 is acted upon in the direction of the first position.

The length compensation element 43 is used to compensate for manufacturing inaccuracies, as well as changes in the distance of the fourth axis 16 to the first axis 10 compensate. Changes may result from the fact that the first cover element 9 by means of an adjustable hinge 51 on the cabinet lid 2 is pivotally mounted. This avoids that when adjusting the hinge 51 also a setting of the articulation point of the actuating arm 13 on the second cover element 11 is required.

It also works due to the spring 49 a spring force vertically downward on the second cover element 11 when the folding lid 8th is in its closed position. This creates a moment through which the folding lid 8th to the body 1 is attracted.
