Hinge to be attached to an inner surface

The furniture industry and in particular the 'kitchen furniture industry, Like the numerous electrical appliance manufacturers, increasingly more resistant, invisible hinges are required with automatic lock, but at the same time easy and are to be installed in an economical manner. Hence will

the development of hinges by the manufacturers. borrowed research in order to meet the growing demands of the trade.

The present invention relates to a hinge to be attached to an inner surface, in which no indentations or indentations are required in the walls intended to accommodate it and yet remains invisible and ensures the complete coverage of the edge of the door with the side wall of the furniture, whereby a complete and compulsory closing, an individual-resistant support even for particularly heavy doors (refrigerator door) and, furthermore, if desired _3, a latching device is ensured at the end of the movement, which maintains the closed state even without the use of locks or snap locks or the like. The hinge according to the invention can be attached not only to vertical doors that open horizontally by 90 °, but also to doors of so-called secretary-like furniture that rotate 120 ° to move from a closed position inclined by 30 ° with respect to the vertical to the to get horizontal position in which they serve as a writing surface.

The moving parts that form the hinge according to the invention consist of two crossed pairs of levers, each lever of the first pair being hinged to the same pivot of the corresponding lever of the second pair is. In addition, the two converging ends of the two levers forming the first pair are with one another articulated and the two converging ends

of the two levers forming a jsweite pair are also articulated to one another , so that an articulated parallelogram is formed in which the two last-mentioned, mutually opposite articulated connections in the closed position are on the Winkelhelblerenden of the angle that of the fixed part of the furniture and of the Door is formed, while the other two (diverging) ends of the first pair of levers each on the fixed furniture part 'or are hinged to the door and the other (diverging) ends of the second pair of levers are each slidably hinged to the fixed furniture part or to the door »

With reference to the figures, the invention wlvä example. explained in more detail. It shows

Figure 5 is a Schragansicl.it a third AusfOhrungsform of the hinge according to the invention with an opening angle of 90 ° in a half-open position in which the levers of one pair of width _s are formed by plate-shaped while the levers of the other pair an edgewise .form perpendicular to these plates, have and are guided between the two guide walls, which are internally provided with indentations on the receiving of the sliding peg.

As can be seen from the schematic representation of FIGS. 1 and 2 , the hinge according to the invention consists essentially of zx \ rei pairs of crossing levers 10-10 ^f or 11-11 ', the lever 10 of the first pair at 12 on the lever 11 of the second pair is articulated and the lever 10 of the first pair is articulated at 12 'em lever 11' of the second pair. In addition, the two adjacent or converging ends of the first pair 10 ~ 10- ^f are articulated to one another at 13 and the two adjacent or converging ends of the second pair 11-11 'are hinged to one another at 13', whereby a glicdervlereck is formed which has the joints 12-12 ^{ , 13-13 '£ U vertices. Finally, the two diverging ends of the first pair JO-IO 'are hinged at lA to the fixed part 15 of the furniture and the other at lk ^f to the opening door 1β, choosing the two diverging ends of the second pair of levers 11-11 " are each articulated on the sliding pin 17 or the other on the sliding pin 17 'of a base plate 18 or 18' so that they create a forced movement within the recess or the slot 21 or 21 'of these base plates 18 or 18'.

In other embodiments, oils portions of each pair of levers can au erreiöhenc In Pail of the hinge shown in Figures 3 and Jf, respectively a are mounted on each side of the folding Sahreibplatte can and the formation of a different profile or one Andore form aufwelsen _s to the desired target and the mutual cooperation of the four interlocking. Lever is. in such a way that the horizontal position of the writing surface is at the same height as the inner panel of the piece of furniture and optimal resistance of the protruding part is ensured, without the need for diagonal struts or support segments.

When used on secretary-like furniture, the levers of each pair are arranged in two different planes ₉ whereby they are allowed to protrude laterally so that they can support each other with their complementary contact surfaces at the end of the movement, whereby in the open position (Figure 3) a rigid and fixed rail is formed, which acts like a one-piece rail.

In fact, in FIGS. 3 and 4, the levers 10-10 'of the first pair have an extension 22-22' with a convex curved profile in addition to the hinge point 13, which exactly fit into a similar concave profile of the levers 11-11 ', whereby a uniform surface is formed which is fixed in the open position (Figure 3).

The hinge according to the invention has the considerable advantage that, with simple changes in the dimensions or shape of the levers forming the two pairs, both in the closed and in the open state, the edge of the door is completely flush with the outer wall the piece of furniture or even a spring back of the door and vice versa, allows to change swar- ₉ and without the feature of the invention.

So the different parts of the hinge can also be made of different materials ₃ which are now commercially available, whereby for example the thin metal parts are often connected to the thicker plastic, whereby a smooth and smooth functioning is achieved without lubrication .
