EP0398192B1 - Hinge, preferably for linking a door or flap to a wall of a body - Google Patents

Description

The invention relates to a hinge, preferably for articulating a door or flap to a supporting wall of a body part, with a pot-shaped pivotable hinge part and with a hinge arm which can be fastened to the supporting wall via a supporting plate and which are articulated to one another by two links (see the patent document DE- A-3442421).

A door hinged with such a hinge executes a pivoting movement when it is opened, in which the narrow end face of the door located on the articulation side migrates laterally with its outer edge over the end region of the door in the closed position. This can usually be accepted because normally there is a free space adjacent to the hinged narrow end face of the door or there is a sufficiently large gap between this end face and the end face of an adjacent door or adjoining components so that the outer edge abuts that between the narrow face and the front of the door is formed, is not to be feared when opening. Problems arise, however, if, for example, a thick door only adjoins an adjacent door or another component with a narrow gap, or if decorative strips or ornaments are attached to the outside of the door in the joint area, which thicken the door in this area or form projections.

The object of the invention is therefore to provide a hinge of the type mentioned, which enables a wide opening of the door even without hindrance if the door has a large thickness or a large distance between the bore for the pivotable hinge part and the narrow end face of the joint Has door and is arranged with only a narrow joint adjacent to an adjacent door or an adjacent component or in addition with decorative strips or the like. is provided.

According to the invention, this object is achieved in a door of the generic type in that a link extends beyond the hinge pin mounted on the hinge arm and in the area of this extension either articulated via a link forming a coupling or by means of a slot-like guide with a pin of the support plate or is connected to an intermediate plate that can be connected to this in such a way that when the handlebar is pivoted, the hinge arm is pivotally and longitudinally displaceably held on the support plate or the intermediate plate by means of elongated bolt guides.

In the hinge according to the invention, the hinge arm executes a pivoting movement inward with a simultaneous displacement outward when the pivotable hinge part is pivoted into its open position, so that the gap between the joint-side end face immediately occurs with the opening of the door the door and an adjacent component and between the inside of the door and the end face of the supporting wall carrying this considerably. The hinge arm thus performs a pivoting movement opposite to the door with simultaneous displacement outwards, so that the hinged edge region of the door is displaced inwards and outwards from the closed position when it is opened, so that there is a sufficiently large free space if the door has a considerable thickness or the like with decorative strips. is provided.

Since in the hinge according to the invention the hinge arm performs a translational movement to the outside during the opening movement, which is superimposed on a pivoting movement counter to the pivoting movement of the door, the pivotable hinge part, which forms the door stop part, can be formed with only a small depth, so that the invention Hinge with appropriate training is particularly suitable for hinging glass doors.

Due to the mobility of the hinge arm, a large opening angle can be achieved with the hinge according to the invention. This is smaller than the opening angle of so-called wide-angle hinges. For this, however, the hinge according to the invention can be manufactured more compact, robust, space-saving and cheaper.

According to an advantageous embodiment, it is provided that the rear and front areas of the side legs of the hinge arm and the side parts of the support or intermediate plate are connected to one another by means of elongated bolt guides, of which at least the front elongated holes of the guides extend at an acute angle to the outside .

According to an advantageous embodiment, the inner link is extended beyond the hinge pin which supports it on the hinge arm and is articulated in the region of the free end of the extension via the link forming a link to the base plate or intermediate plate. This embodiment has the additional advantage that a particularly large opening angle can be achieved, which normally cannot be achieved with hinges of the type required by the preamble of claim 1.

According to another embodiment it is provided that the inner link is extended beyond the hinge pin mounted on the hinge arm, that this extension is provided with a slot-like guide for the bolt or bolts of the support or intermediate plate and that the bolt or bolts is additionally in the front elongated holes of the legs of the support arm are guided. The slot-like guide in the extension of the handlebar can be provided in the legs of the cross-sectionally U-shaped handlebar or it can also be formed by a hairpin-shaped loop of the extension.

In the exemplary embodiments described above, the rear, displaceable, articulated connection consists of a long slot guide with an elongated hole running approximately parallel to the support plate, while the long hole of the front long slot guide rises obliquely outwards, that is to say, moves away from the support plate. is designed so that when the pivotable hinge part pivots in its open position, the hinge arm executes a pivoting movement inwards with a simultaneous displacement outwards and consequently immediately with the opening of the door the gaps between the hinged end face of the door and one adjacent component and between the inside of the door and the front of the supporting wall carrying this considerably enlarge. The hinge arm thus performs a pivoting movement opposite to the door with simultaneous displacement outwards, so that the hinged edge area of the door is displaced inwards and outwards from the closed position when it is opened, and thus there is a sufficiently large free space if the door is one has considerable thickness or the like with moldings. is provided. This opposite pivoting movement of the hinge arm, however, leads to the fact that the inwardly pivoted door narrows the clear width of the furniture and thus the pulling out of any sliding parts, such as drawers or the like. prevented.

According to a particularly preferred embodiment it is therefore provided that the rear articulated connection consists of a coupling member which is articulated in the region of the rear end of the hinge arm on the one hand with this and on the other hand with the support or intermediate plate, and that the coupling member has such a length that the hinge arm performs at the rear region at least with its rear region a lifting movement when pivoting the pivotable hinge part into the open position, which movement is superimposed on the translationally outward movement of the hinge arm. In the hinge according to the invention, due to the kinematics of the connection of the hinge arm to the support or intermediate plate, this is given a pivoting movement at least towards the end of the opening movement of the door, which is aligned with the pivoting direction of the opening door.

In order to ensure that the opened door is pivoted completely out of the clear width of the furniture, it is provided according to an advantageous embodiment that the elongated hole Bolt slot guide in the direction of the pivotable hinge part is sloping towards the supporting wall. This configuration makes it possible to ensure that a door opened by 90 ° is flush with the inside of the body part carrying it, if it is not even offset to the outside thereof.

Of course, the slot of the bolt-slot guide can have an inclination or curvature corresponding to the desired pivoting characteristic of the hinge arm.

Even if the course of the slot of the bolt-slot guide is not designed so that the open door is pivoted out of the clear width of the furniture, it can be selected in such a way that at least the pivot angle permitted by the joint system is full can be exploited or even enlarged because the hinge arm does not perform a pivoting movement opposite to its pivoting movement when the door is pivoted.

Advantageously, the coupling member is articulated to a rear raised part of the support or intermediate plate, so that the coupling member can give the desired movement to the rear end region of the hinge arm in a simple manner.

The coupling member expediently consists of a U-shaped bracket, on the web parts of which adjoining regions of its legs are articulated on the supporting or intermediate plate.

Particular embodiments of the invention are explained in more detail below with reference to claims 5 and 6.

The hinge shown in FIGS. 1 to 12 consists of a pivotable cup-shaped hinge part 1, which is articulated in a conventional manner with the cross-sectionally U-shaped hinge arm 6 by the links 2, 3 via the hinge pins 4, 5. In the pot-shaped hinge part 1, the outer ends of the links 2, 3 are mounted on hinge pins 7, 8. The pivotable cup-shaped hinge part 1 is embedded in a milled hole 9 in the door 10 and fastened to the door 10 in the usual manner. The cup-shaped hinge part 1 forms the pivotable door stop part and can also have any other suitable shape. The inner link 3 is provided with an extension 11 which extends this beyond the bore 12 or the hinge pin 5.

A support plate 14 is screwed to the support wall 13 and is connected to a first intermediate plate 15 and a second intermediate plate 16 in the manner shown in FIGS. 1 and 2. The first intermediate plate 15, which is U-shaped in cross section, is connected to the support plate 14 by the fastening screw 17 which engages in a keyhole-like elongated hole 18 in the web part of the first intermediate plate 15. The elongated hole 18 enables the hinge arm 6 to be adjusted in its longitudinal direction.

The second intermediate plate 16, which likewise has a U-shaped cross section, is mounted on the first intermediate plate 15. The set screw 21 is screwed into the flanged threaded bore 20 of the web part of the second intermediate plate 16 and engages with its annular groove 22 in an elongated hole 22 'which runs freely out towards the front in the web part of the first intermediate plate 15. In the rear area of its legs, the second intermediate plate 16 is provided on its inside with pin-like projections 23 which are guided in elongated holes of the first intermediate plate 15 which run freely towards the rear. The intermediate plate 15 is provided in the front region of its legs with a bolt or pin-like projections 24 ′ which engage in obliquely extending slots 25 in the legs of the second intermediate plate 16. If an adjustment is made by means of the adjusting screw 21, the second intermediate plate 16 carries out a pivoting movement which is overlaid by a translational movement, so that the joint between the door and the body part is not changed when the door is adjusted to the side. This embodiment has been described in DE-PS 34 42 421, to which reference is made for further illustration.

The hinge arm 6 carries in the rear and front areas of its legs which are angled in a U-shape from the central web part, on the inner sides of which knob-like projections 30, 31 which, as guide bolts or guide pins, engage in elongated holes 32, 33 of the upper intermediate plate 16, which at least from the hinge arm 6 is partially bordered. The elongated hole 32 is located in the rear area of the legs of the intermediate plate 16, while the elongated holes 33 are located in the front areas thereof and freely run out toward the front. The elongated holes 33 run upward at an acute angle.

In the bores 12 of the legs of the extension 11 of the inner link 3, a bolt 35 is held, on which the upper rolled eye of the link 36 forming a coupling is mounted. The lower rolled eye 37 of the handlebar is mounted on a pin 38 which is held in bores 39 of the side legs of the upper intermediate plate 16. The bolt 38 is located below the inner end of the elongated hole 33.

When the door 10 or the pot-shaped hinge part 1 opens, the hinge arm 6 rotates about an imaginary pivot axis, the geometric location of which is defined by the intersection of the perpendicular of the guide pins 30, 31 and the elongated holes 32, 33. The pivoting movement of the hinge arm 6 during the opening movement of the door can be selected by a corresponding choice of the arrangement and the course of the elongated holes 32, 33 and by the arrangement of the handlebars supporting the handlebar 36 and the length of the handlebar.

As can be seen from FIG. 5, the bores 40 of the inner link 3 have edges that are flanged outwards. These flanges can be formed by punching and allow the handlebars to be adapted to the width of the hinge arm as well the other hinge parts. Flanging the bores 40 also improves strength.

In the exemplary embodiment according to FIGS. 13 and 14, the rear guide pins 30 'are provided on the outside of the legs of the upper intermediate plate 16 and these engage in freely extending slots 32' in the rear region of the legs of the hinge arm 6 '. In their front area, the legs of the hinge arm 6 'are provided with elongated holes 33' which run upwards at an acute angle. The pin-shaped ends of a bolt 31 'which project outward beyond the legs of the intermediate plate 16' and which is held in corresponding bores in the legs of the upper intermediate plate 16 engage in these elongated holes. The inner link 3 'is provided with an extension 11' which is curved in a hairpin-shaped manner such that a guide gap 42 is formed between the legs thereof. The bolt 31 'is guided in this guide gap 42.

15 to 18 consists of a pivotable cup-shaped hinge part 1, which is articulated by the link 2, 3 via the hinge pin 4, 5 in a conventional manner with the cross-sectionally U-shaped hinge arm 6. In the cup-shaped hinge part 1, the outer ends of the links 2, 3 are mounted on hinge pins 7, 8. The pivotable cup-shaped hinge part 1 is embedded in a milled hole 9 in the door and fastened to the door 10 in the usual way. The cup-shaped hinge part 1 forms the pivotable door stop part and can also have any other suitable shape. The inner link 3 is provided with an extension 11 which extends this beyond the hinge pin 5.

With the support wall 13, a support plate 14 is screwed, which in 1 to 14 described manner is connected to a first intermediate plate and a further intermediate plate 16. The first intermediate plate, which is also U-shaped in cross section, is connected to the support plate 14 by a fastening screw which engages part of the first intermediate plate through an elongated hole in the web part. The second intermediate plate 16, which also has a U-shaped cross section, is mounted on the first intermediate plate. A set screw 21 is screwed into a flanged threaded bore of the web part of the second intermediate plate 16 and engages with its annular groove in an elongated hole that runs freely towards the front in the web part of the first intermediate plate. In the rear region of its legs, the first intermediate plate is provided with peg-like projections 23, which are guided in elongated holes 24 of the second intermediate plate 16 that run freely towards the rear. The intermediate plate 16 is provided in the front region of its legs with a bolt-like or pin-like projections which engage in obliquely extending oblong holes after the legs of the first intermediate plate. If an adjustment is made by means of the adjusting screw 21, the second intermediate plate 16 carries out a pivoting movement which is overlaid by a translational movement, so that the joint between the door and the body part is not changed when the door is adjusted to the side. This embodiment has been described in DE-PS 34 42 421, to which reference is made for further illustration.

The hinge arm 6 carries in the front areas of its legs which are angled in a U-shape from the central web part on the inner sides of nub-like projections 30 which engage as guide bolts or guide pins in elongated holes 33 of the upper intermediate plate 16 which is at least partially surrounded by the hinge arm 6. The elongated hole 33 runs obliquely, in such a way that it extends towards its free end towards the Body part or the support plate 14 approximates.

In the bores of the legs of the extension 11 of the inner link 3, a bolt 35 is held on which the upper rolled eye of the link 36 forming a coupling is mounted. The lower rolled eye 37 of the handlebar is mounted on a pin 38 which is held in bores in the lateral legs of the upper intermediate plate 16. The bolt 38 is located below the elongated hole 33.

The lateral legs 60 of the hinge arm are provided with these extensions 61 which extend rearwards and which project beyond the web part 62 of the hinge arm 6. The fork-shaped extensions 61 are provided with bores, in each of which short riveted bolts 63 are held, penetrate the bores 64 in the legs 65 of the bow-shaped coupling member 66 and thereby pivotally connect them to the extensions 61. The legs 65 of the bow-shaped coupling member 66 are provided with further bearing bores 68 in their area near the web 67.

From Fig. 16 it can be seen that the described gearing connection of the hinge arm 6 to the intermediate plate 16 ensures that the inside of the door 10 opened by 90 ° is flush with the inside of the body part 13.
