Description

The invention relates to a hinge for the articulated connection of two partial wings of a door leaf, of which a partial wing or the like on a body part of a piece of furniture. is articulated, consisting of two stop parts which can be connected to each of the partial wings and which have hinge arms connected to one another by a joint.

Such a hinge is usually used for the articulated connection of the partial wings of a two-part corner cabinet door wing and is known for example from DE-OS 37 29 531. This known hinge consists of two pot-shaped fastening fittings forming the stop parts, which are let into their mounting in corresponding flat blind hole-like cutouts, which are cut from the narrow end faces of the partial wings. With one of these fastening fittings, a fork-shaped hinge arm is integrally connected, which between its forked parts encloses an angled part of the other hinge arm, which is screwed to the other fastening fitting. In addition to the fact that the assembly of the known hinge because of the required millings to accommodate the holding pots

Fastening fittings is complex, this can be adjusted after assembly only by longitudinally displacing one hinge arm on its fastening fitting, so that the possibilities for subsequent adjustment of the partial wings relative to one another are very limited.

The object of the invention is therefore to provide a hinge of the type specified which can be adjusted in a simple manner with simple assembly.

According to the invention, this object is achieved in a hinge of the generic type in that the stop parts consist of base plates on which the hinge arms are adjustably fastened in the direction of their longitudinal direction and / or in at least one transverse direction thereto.

The hinge according to the invention can be installed in a simple manner in that its hinge arms are fastened to base plates which are screwed to the edge regions of the inner sides of the partial wings. To fix the base plates, only the usual fixing holes have to be drilled into which the fixing holes of the base plates are screwed. The hinge arms are then attached to the base plates in a manner known from conventional furniture hinges.

The base plate expediently consists of a base plate and at least one intermediate plate which can be displaced or pivoted relative to the latter and can be fixed in a displaced or pivoted position and which carries the hinge arm. Such base plates bearing a hinge arm are known from EP patent publication 0 348 656 A1, so that they can be used because of the closer design of the base plate and the base plate and the

Intermediate plates can be referenced. The base plates for fastening the hinge arms of the hinge according to the invention can in principle be designed in the same way as the base plates known from the EP publication. The hinge arms can thus be screwed to the base plate or an intermediate plate or connected to them by a snap connection.

In the hinge known from DE-OS 37 29 531, the fastening fittings for the two hinge arms are designed differently, which means an increased manufacturing outlay. According to an advantageous embodiment of the invention it is provided that the base plates for both hinge arms are identical, which considerably reduces the manufacturing costs and the necessary storage for the hinge parts.

In the hinge known from DE-OS 37 29 531, the hinge arms connected to the two fastening fittings are also designed differently, which in turn means an increased production outlay. In contrast, according to a further inventive embodiment, it is provided that each hinge arm has an angled part which, in the assembled state, extends over the narrow end face of the partial wing and which, at the end adjacent to a step-shaped recess formed by a shoulder, has a lateral cantilevered cheek which extends into the Paragraph of the other angled part, which is of the same mirror image, engages, and that both cheeks are provided with an aligned bearing bore which passes through a bearing pin which connects them in an articulated manner.

The hinge known from DE-OS 37 29 531 is designed as a snap hinge, the snap mechanism consisting of a rod articulated with a mounting bracket with a head thickened at the end and a locking step into which a nose of a pivotally mounted in the other mounting bracket, spring-loaded lever engages.

When the door leaf is open, this snap mechanism becomes ugly visible. In a further embodiment of the invention, it is therefore provided that each bearing bore in the region of the recess has a cam cam partially surrounding it, on the circumferential surface of which a spring-loaded slider is supported, which is guided in a bore of the step formed by the extension. By designing the The circumferential surface of this cam curve can achieve the desired opening and closing characteristics of the hinge.

The cam curve expediently has such a characteristic that the angled parts of the hinge arms tend to pivot towards a smaller pivoting angle starting from an angle which is slightly greater than 90 '. Such a closing characteristic secures the closed position of the two-leaf door, in which the partial leaf of an angle cabinet is at an angle of approximately 90 °. Relative to the door leaf, the closing characteristic is such that the angled parts of the hinge arms tend to pivot them relative to one another in the direction of a larger swivel angle.

The closing characteristic can also be designed so that in the area of a pivoting angle of the door leaf, which is slightly smaller than 180 degrees, it tries to pivot it into an aligned position in which the angled parts of the hinge arms lie approximately parallel to one another and abut one another laterally.

Finally, the cam curve can have such a design that in a swivel range of the angled parts of the hinge arms, which is approximately between 80 ° and 10 °, they do not exert a moment on the partial wings.

Finally, a nose can be provided in the end region of the cam curve, which in the angled position of the partial wings abuts against a counter-stop of the angled part of the other hinge arm and thus limits the smallest pivoting angle of the partial wings.

According to a particularly advantageous embodiment, it is provided that both hinge arms are of identical design, so that manufacture and storage are further simplified in this respect. Since both the base plates and the hinge arms can be designed identically, the hinge according to the invention can be mounted on the right and on the left, with simple adjustment also being ensured.

• 7 shows a section through the hinge arm along the line VII-VII in Fig.5 and
• 8 shows the pressure piece sliding on the cam surface in a side and top view. From FIG. 1 a double-wing door consisting of the outer wing 1 and the inner wing 2 of a corner cabinet can be seen, of which the inner wing 2 by wide-angle hinges 3 of conventional design a load-bearing side wall 4 of the corner cabinet is articulated. In the position shown in full lines, the door 1, 2 is in its closed position, in which the partial wings 1, 2 assume a position perpendicular to one another. The two partial wings 1, 2 are connected to one another by hinges 5, one of which is described in more detail with reference to FIGS. 2-7.

To open the two-leaf door, the partial wing 1 is pivoted in the direction of arrow A into the dot-dash position 1 ', so that the partial wing 1 can be pivoted past the following door or wall without hindrance. The open door, in which the partial wings 1 "and 2" assume an aligned position, that is to say lie in one plane, is also shown in dash-dot lines.

An enlarged hinge 5 is shown in an enlarged representation from FIG. The hinge consists of identically designed base plates 6, 6 'on which identically designed hinge arms 7, 7' are held, so that only the base plate 6 and the hinge arm 7 are described in more detail below.

The base plate 6 consists of a base plate 8, which is provided in a manner not shown with mounting holes through which the mounting screws, not shown, grip, through which this is screwed to the wing part 2. With the base plate 8 is an intermediate plate 10 carrying the hinge arm 7 screwed to the hinge arm 7, is connected in basically the same way to the hinge arm 7 as the intermediate plate shown in FIG. 2 of the European patent publication 0 348 656 A1, so that this European one Patent publication is referred to the intermediate plate and the type of connection of the hinge arm 7 with this intermediate plate.

The base plate 6 can also have the structure shown in FIG. 2 of EP 0 348 656 A1, the intermediate plate 10 directly with the lower intermediate plate screwed or with this, as can be seen from the EP publication, can be locked by a snap connection.

The fastening screw 9 engages through a keyhole-like elongated hole 11 of the intermediate plate 10, so that the basic setting of the hinge arm 7 can be achieved in that the intermediate plate connected to the hinge arm is pushed back as far as the stop on the fastening screw 9. The hinge arm 7 is U-shaped in the manner shown and is articulated by a hinge pin 12 to the rear end region of the intermediate plate 10, which is also U-shaped. In lateral legs, the intermediate plate 10 has elongated holes 13 in its front area, into which guide pins 14 engage, which are fastened to the inner flanks of the legs of the U-profile of the hinge arm 7. By turning the adjusting screw 15, which is screwed into the web part of the hinge arm, a side adjustment of the hinge arm 7 can be effected. The set screw 15 is provided with an annular groove which engages in a freely running elongated hole in the intermediate plate 10.

Furthermore, the base plate 8 can have an additional intermediate plate, which allows a height adjustment of the hinge.

The hinge arm 7 has a front angled part 20 which engages over the narrow end faces of the partial wings 2, 1 in the manner shown in FIGS. 2 and 3. This angled part 20 has at its lower free end a recess 21 which is formed by a step-shaped shoulder. A bore 23 opens into the step surface 22 and runs in the longitudinal direction of the angled part 20. The outer part of this blind hole 23 has an elongated profile with opposite rounded sides, which corresponds to the cross section of the slider 24, which can be seen from Figure 8b. In this way, the slider 24 is held non-rotatably in the bore 23. A compression spring 26 is clamped between the rear of the slider 24 and the bottom of the bore 23, as can be seen in FIG. 2, and presses the slider with its roof-shaped beveled front edge 27 against the cam curve 28. The cam curve 28 is provided on a projecting projection 29 which laterally delimits the recess 21. The projection 29 is provided with a bore 30 which is aligned with the bore 30 in the corresponding projection of the complementary hinge arm 7, the aligned bores of the hinge pins 31 being passed through for the articulated connection of the two hinge arms 7, 7 '.

As can be seen from FIG. 6, the cam curve 28 has a section 35 which, in the closed position shown in FIG. 2, exerts a closing pressure on the partial wings 1, 2. The section 35 is adjoined by a central curve section 36, which is curved concentrically around the hinge pin 31, that is to say has a constant radius, so that the cam curve lies in a region between the closed position and the open position of the partial wings, in which the latter take an aligned position with each other, no moment is exerted on them. A section 37 with a decreasing radius adjoins the concentric curve area and secures the open position of the partial wings 1 ″, 2 ″ shown in FIG.

Finally, the cam curve is provided at its outer end with a nose 38, which cooperates with the counter-stop 39 and limits the smallest angle that the partial wings 1, 2 can take. This angle can be seen in FIG. 1 and is given between the position of the partial wings 2, 1 '.

Since, due to the mirror-image design of the hinge arms 7, 7 ', both the cam curves 28 provided on the projections 29 and the spring-loaded sliding pieces 24 are provided twice, the spring-loaded sliding pieces 24 sliding on the cam curves are able to exert considerable closing and opening moments, due to the division the closing forces on each individual locking device show only a slight wear.

The spring-loaded sliders cooperating with a cam curve are known per se from DE-OS 29 47 153 for a hinge of a different type.

When assembling the hinge arms 7, 7 ', they can be pushed back before tightening the fastening screws 9 until they abut the shaft of the fastening screw 9, which then ensures the basic position. The slot 11 allows adjustment of the hinge arms in the longitudinal direction.

It is particularly advantageous if the base and intermediate plates 8, 10, possibly with the arrangement of a further intermediate plate, permit a height adjustment of the hinge arm 7, that is to say an adjustment of the hinge arm 7 parallel to itself.

If a further negative setting of the hinge arm, that is to say a further shifting back, is no longer possible, an adjustment of the other partial wing in the corresponding direction is nevertheless possible by actuating the screw 15. Because by actuating the adjusting screw 15, the door leaf is pivoted relative to the hinge arm. Such pivoting would have been achieved, for example, by actuation the set screw 15 'in Figure 2 the result that the partial wing 1 in the closed position shown is further approximated to the partial wing 2, because both hinge arms 7,7' are connected to each other by the hinge pin 31.
