In particular, from Figures 1, 3 and 5 is an upper cabinet 1, which is attached in height hanging on a building wall becomes. The body of the cabinet 1 has two each other opposite, vertical side walls 2, of which in the Drawing only one is visible, a bottom wall 3, a ceiling wall 4 and a not shown in detail back wall on.

The front of the upper cabinet 1 is associated with a folding flap 5, in their resulting from Figure 1 closed position is vertically aligned and closes the cabinet interior. The folding flap 5 can from this closed position in a the access to the cabinet interior gestattende open position (Figure 3) are adjusted, the opening movement on the intermediate position shown in Figure 5 takes place. It understands itself that when closing the folding flap 5, the reverse Processes proceed and thus also the intermediate position according to Figure 5 is traversed.

The folding flap 5 is divided into two parts and is replaced by a first, arranged above folding element 6 and a second, arranged below Folding element 7 formed by two in each case one of the two lateral end portions of the folding flap 5 arranged Hinges 8 hinged together, only one of which is shown in the drawing.

In the closed position, the two folding elements 6, 7 in a same level next to each other, i. the second Folding element 7 is in the same vertical Level below the first fold element 6. When transferring to the open position lead the two folding elements 6, 7 in opposite directions Pivoting movements by the first folding element 6, that with his the second folding element 7 opposite Border area over a detail not of interest here Hinge fitting 9 pivoting at the top with the Cabinet 1 is connected, pivots away from the cabinet 1 while the second folding element 7 from its first folding element 6 coplanar position pivots toward the cabinet 1, so that the Folding flap 5 folded a little way.

On the second folding element 7 is at a distance from the hinge 8 a Steering lever 10 articulated, the other end pivotally with the facing Sidewall 2 is connected and the movement of Folding flap 5 controls. The arrangement may, however, in this regard also be different. This is of interest in the present context not further.

The hinge 8 has a support arm 11 which with his an end portion 12, which in the embodiment of a Fixing plate is formed on the first folding element 6, expediently by means of fastening screws attached becomes. The attachment takes place at the in the closed position the inside of the cabinet facing inside 12 of the first Folding element 6. The support arm 11 is in the attached state over the second folding element 7 facing edge 14 of the first folding element 6 before.

The hinge 8 further includes a second folding element 7 fixing part 15 to be fastened. The fastening part 15 is expediently on the inside 16 of the second folding element 7 attached. Again, this can be done with the help of suitable mounting screws respectively. The hinge 8 further has a hinge arm arrangement, on the one hand on the Attachment end portion 12 of the support arm 11 opposite another support arm end portion 17 at a first hinge axis 18 and on the other hand on the fastening part 15 at a second Hinge axis 19 is articulated. This hinge arm arrangement is from a first hinge arm 20 and a second Hinge arm 21 formed. The first hinge arm 20 is over the first hinge axis 18 on the support arm 11 and the second Hinge arm 21 via the second hinge axis 19 on the fastening part 15 hinged. The first and the second hinge axis 18, 19 opposite ends of the two hinge arms 20, 21 are articulated via a third hinge axis 22 connected with each other. Here are the two hinge arms 20, 21, starting from the first and the second Hinge axis 18, 19, attached to the folding elements 6, 7 Hinge 8 directed to the first folding element 1 out.

When closing the folding flap 5, the facing each other Edges of the two folding elements 6, 7 to each other. It may happen that when you press the folding door 5, if you are in the area of between the two folding elements 6, 7 existing gap against the folding elements presses, with the fingers 23 in the said gap device (see Figure 6). To a painful pinching of the fingers 23, a safety device is provided, so that when clamping an object, for example the finger 23, the gap between the two folding elements 6, 7 enlarged.

The safety device has a locking member 24; 24a am Support arm 11 and a latching element 25; 25a on the second hinge arm 21, wherein the arrangement is such that at ineffective safety device, i. if nothing is trapped is and the hinge assumes its normal position, the second hinge arm 21 and the support arm 11 via the locking member 24; 24a and cooperating with this locking element 25; 25a are latched together (Figures 1 to 5 and 9). These Locking becomes automatic when a release force occurs solved. This release force arises when pinching the fingers 23 between the two folding elements 6, 7. Is the locking solved, the second hinge arm 21 is released from the support arm 11, so that the formed by the two hinge arms 20, 21 Hinge arm arrangement can be opened, so to speak, and the second Folding element 7 under enlargement of said gap from the first folding element 6 far enough away.

The locking member 24; 24a and / or the latching element 25; 25a are expediently designed or arranged elastically yielding. When folding the hinge arm assembly 20, 21, if after a Einklemmfall the safety device to return to their original state, meet the locking member 24; 24a and the locking element 25; 25a each other and lock under elastic deflection in a row.

The elastically resilient locking member 24; 24a and / or locking element 25; 25a is suitably made of plastic. At the Embodiment is only the sitting on the support arm 11 Locking member 24; 24a made of compliant plastic while the locking element 25; 25a formed by a metal part becomes.

In the case of Figures 1 to 8, the elastically yielding Detent member 24 has a latching edge 26 for latching behind by the locking element 25. In the variant of the figures 10 and 11 forms the elastically yielding locking member 24a contrast, a detent slot 27 with a tapered slot mouth 28, so that the locking element 25a through the tapered Slot opening 28 enters the locking slot 27 and the Slotted opening 28 latching behind engages.

In the case that one arranged on the second hinge arm Locking element elastically yielding forms, results the reverse arrangement.

The locking member 24a of the variant according to FIGS. 10 and 11 is designed like a clamp and stands up from the support arm 17. The staple-like design makes two staple legs 29, 30 are formed, which limit the locking slot 27. at the variant according to Figures 1 to 9, the locking member 24th on the other hand, a block-like shape with arranged on its outside Latching edge 26 on.

Is the second hinge arm 21 locked with the support arm 11, also the first hinge arm 20 is held, since he yes on the one hand on the support arm 11 and on the other hand on the second hinge arm 21 is articulated. Thus forms with the support arm 11th latched second hinge arm 21, the second hinge axis 19, the hinge joint to which the support arm 11 and the Fixing member 15 can pivot relative to each other.

The first hinge arm 20 has two spaced apart extending hinge arm legs 33, 34 on. The second Hinge arm 21 is so wide that it is between the two mentioned Hinge arms 33, 34 fits. In this way can the two hinge arms 20, 21 with the support arm 11th latched second hinge arm 21 a folded, occupy substantially parallel to the support arm 11 extending position.

The support arm 11 is in its area, beyond the time the first hinge arm 20 extends, in cross-section U-like formed so that the two hinge arms 20, 21, is the second hinge arm 21 latched to the support arm 11, in the Can plunge support arm 11.

The locking member 24; 24a is from the support arm 11 between the Hinge arm arms 33, 34 of the first hinge arm 20 therethrough high, when it with the arranged on the second hinge arm 21 Latching element 25; 25a is locked.

The fastening part 15 has a second folding element 7 to be fastened mounting part 35 and a from this in the attached state in the direction of the first folding element 6 facing edge 36 of the second folding element 7 away extending extension section 37, the arm-like shape has and arranged on the second hinge axis 19 is.

The fastening part 15 also has a recess 38, the alignment with the recess 31 of the second hinge arm 21st is arranged when the second hinge arm 21 and the support arm 11 are locked together. The locking member 24; 24a can then, if it is correspondingly high, into the recess 38 plunge.

The pivotal movement of the first hinge arm 20 in the direction away from the support arm 11 by one between the first hinge arm 20 and the support arm 11 effective stop device limited to a maximum acute angle. This maximum Angle is reached in Figure 6. The stop device can be formed, for example, that the first Hinge arm 20 slightly beyond the first hinge axis 18 addition is extended and there forms a stop section 39, the when reaching the maximum acute angle on the support arm 11th strikes.

The maximum swing angle between the second hinge arm 21 and the fastening part 15, however, is expediently an obtuse angle taken in the open position becomes (Figure 4). This is done by a corresponding on the second Hinge arm 21 arranged stop surface 40 reaches, the arrives at the attachment part 15 to the plant.

As already mentioned, in the variant according to FIGS. 10 and 11, the locking member 24a formed like a clamp and forms two the locking slot 27 with the slot opening 28 limiting Clip legs 29, 30, between which the locking element 25 a locked. In this case, the locking element 25a of a locking pin 32 formed. The locking pin 32 has in FIGS. 10 and 11 a circular cylindrical shape. Appropriately, can the locking pin but also formed by a square pin become. This square pencil can have a square cross section exhibit. This square pin is in one such rotational position on the second hinge arm 21 arranged that he latched in with one of his edges progressing between the Clamping legs 29, 30 passes.

This square pin is not shown in the drawing. However, it is readily conceivable that in the figures 10 and 11, the circular cylindrical locking pin 32 by a can replace such square pin.
