This torsion bar forms the axis of rotation for the hinges and is mounted with one end in a guide arranged on the flap and with the other end in a latching device arranged on the furniture wall. The end of the rod resting in the locking device is used ^: to adjust the preload of the torsion rod. Here, the Mach part occurs _s dass'aufgrund the fixed detent positions an accurate adjusting of the hinge to the respective Klappengexfflcht is not given; Furthermore, these brake hinges are unfavorable in their mode of operation and are large in design, so that they take up a large amount of space if the operation is prone to failure and improper handling and are often undesirably visible from the outside, so that they can be used on furniture appear unpleasant.

Furthermore, brake hinges have become known, in which braking bodies are provided around the hinge axes.e between the hinge tabs.

The hinge tabs l4. _s l6 are preferably made of plastic or the like. produced and to save material and weight with recesses or the like. fitted.

The hinge tabs l4 ₃ l6 are by means of screws or the like. attached to the furniture parts 13, 15, wherein it is advantageous ₅ the hinge tabs l4 with thin furniture flaps 13 by means of two-stage dowels 37 and engaging screws 38 or the like. which ensure a secure and permanent hold of the hinge Io _s 11 on the furniture flap 13 * (see Fig. 3 "') ■' -. ■

The two individual hinges Io, 11 are connected to one another by the spring bar (torsion bar) 12, the spring bar 12 being shorter or longer depending on the length of the furniture flap 13. The task of the spring bar 12 is to approximately balance the weight of the furniture flap 13 by pretensioning (twisting) and can be adjusted to the respective flap weights by means of the worm gear 22. By rotating the screw 24 by means of a screw ■ "-. _S executor of the grip-like head 29 or the like, the worm wheel 23 is rotated about its axis of rotation 5 while the hinge pin 18 and is form-fitting enclosing spring bar 12 is simultaneously rotated ₅ whereby a biasing of the the spring rod 12 is reached, the spring rod 12 is replaced by that caused by the worm gear 22 twisting a certain pretension, which allows retention of the weight, various furniture flaps 13 in any desired open ^position: -...

The brake hinge according to the innovation is simple in structure, easy in manufacture and safe in its mode of operation and shows a wide range of uses. Further, this hinge is braking _s arranged in an advantageous manner in the rear or lateral region of the furniture so that it is invisible from the outside. .

It is within the scope of the innovation to implement the cross-sections - the hinge pin and the spring rod in other ways - instead of a worm gear, a similar (non-positive or positive) .acting inhibitor gear, such as friction gear or the like. to be provided. Furthermore, several single hinges can be arranged side by side and. connected to each other with a spring rod zn a brake hinge. ■ - ■ .. - - ■ -. . ^;
