Abstract

A hinge, with a fixed fitting part which is designed as a hinge arm having a baseplate carrying the latter and which is connected to a pivotable fitting part, can, for the lateral setting of a door or flap carried by the pivotable fitting part, be adjusted in relation to the baseplate in the pivoting plane of the hinge by means of an actuating device. A retaining member mounted on the hinge arm and loaded by a resilient element presses the pivotable fitting part in the closing region into its closing position via a control cam pivotable together with the pivotable fitting part, whilst, outside the closing region, it is rendered ineffective by a control cam. In order, even during lateral adjustment by a pivoting of the hinge arm, to ensure that the closing device maintains its effectiveness unchanged in the closing region, the mounting of the retaining member is connected to the hinge arm and to the baseplate by means of guides (27,28) and/or gear members, in such a way that, as a result of any pivoting of the hinge arm relative to the baseplate, the retaining member is moved into a position in which it maintains essentially the same position relative to the control cam (35,36,37) in the closing position. <IMAGE>

Description

The invention relates to a hinge, preferably a furniture hinge, with a fixed fitting part designed as a hinge arm with a base plate supporting it, which is preferably connected via articulated lever to a pivotable fitting part, preferably a hinge cup, and for the lateral adjustment of a door or carried by the pivotable fitting part Flap is pivotable relative to the base plate by an actuating device in the pivoting plane of the hinge, and with a locking member mounted on the hinge arm and acted upon by a resilient element, which presses the pivotable fitting part in its closed position in the closed area via a control curve pivotable with the pivotable fitting part and is made ineffective by the control cam outside the closing range.

For example, from DE-PS 34 42 421 it is known to pivot the hinge arm in the pivoting plane of the hinge relative to the base plate carrying the hinge arm for lateral adjustment of a door or flap carried by a furniture hinge. However, if the hinge arm is pivoted away from the base plate fastened to a supporting wall for side adjustment of a door, the hinge arm assumes an obtuse-angled position relative to the door, which corresponds to a slight door opening, although the door is in its closed position by being supported on body parts or a door frame. DE-PS 34 42 421 relates to a furniture hinge, the cup-shaped, pivotable hinge part is connected to the hinge arm by two links with rectangular or trapezoidal hinge pins. In such a four-bar hinge, the joint increases, that is, the distance between the end wall of the supporting wall and the door, so that DE-PS 34 42 421 relates to an embodiment in which the hinge arm in guides of a base or intermediate plate increases in size by a slight door opening is that it is displaced in its longitudinal direction on the base or intermediate plate when pivoting by the amount of the joint change caused by the pivoting.

Hinges of the type specified above, which are provided with only one joint or with two links in the manner described in DE-PS 34 42 421 or with intersecting hinge arms in so-called "wide-angle hinges", are often equipped with locking devices that open the doors or Press flaps in their closed area, i.e. in a small angle area, for example angles of 5 to 8 degrees, into this closed position before their fully closed position. Such a locking device, which consists of a control disc arranged in the region of a joint, on which a spring-loaded pressure member runs, is known for example from DE-OS 24 01 178. The pressure member, which is mounted on a spring-loaded swivel lever and consists of a roller, runs in the opening area on a cam track concentric to the swivel axis, so that the corresponding articulated lever is not loaded in the sense of a closing or opening movement, and only moves towards one in the closing area the curve axis approximating the articulated axis, so that it generates a closing moment in the closing area via the cam disc.

If, however, the door is moved only a small angle into its open position during a side adjustment of the door, the curve branch which is run over by the pressure element and which is in the closed position and which generates a closing torque is shortened accordingly, if not prevented at all, that the pressure element is still not on the a curve area generating closing torque arrives. The side adjustment of a door or flap by pivoting the hinge arm in the pivoting plane of the hinge can therefore have the consequence that a locking device with control cam and pressure element is reduced in its effect or completely canceled.

The object of the invention is therefore to provide a hinge of the type specified in the introduction, in which it is ensured, even in the case of a side adjustment by pivoting the hinge arm, that the locking device remains effective in the closing area.

According to the invention, this object is achieved in a hinge of the generic type in that the mounting of the locking member is guided by guides and / or gear members to the hinge arm and to the base plate in such a way that it is moved into a position relative to the base plate by each pivoting of the hinge arm , in which it maintains its essentially identical position to the control curve in the closed position.

The hinge according to the invention thus compensates for pivoting movements of the hinge arm for side adjustment in such a way that an actuating movement derived from the hinge arm is also transmitted to the locking member in such a way that the actuating movements are compensated for and the locking member in the closing area remains unchanged its position with respect to the control curve in all settings maintains so that the closing moment acting on the door in the closing area remains in effect unchanged. In the hinge according to the invention, the effectiveness of the closing torque of the locking device is not impaired by a side adjustment, so that it always remains effective regardless of the setting over the same small opening angle corresponding to the locking area.

The invention can preferably also be implemented in a hinge in which the pivotable hinge part is connected to the hinge arm by two articulated levers, one of which carries the control cam on the hinge arm in the region of its articulated axis.

The invention can in particular also be realized with a hinge of the type known from DE-PS 34 42 421 additionally provided with a locking device, with two adjustments then being made simultaneously when the hinge arm is pivoted for lateral adjustment, namely once the longitudinal displacement of the hinge arm for retention an unchanged joint gap, and on the other hand the adaptation of the locking member to the control curve according to the invention.

According to a preferred embodiment, it is provided that the locking member consists of a spring-loaded lever, the hinge axis of which is guided in intersecting elongated hole guides of the base plate or an intermediate plate fastened on this and the hinge arm, that its pressure piece interacting with the control cam relative to the latter in the closed position maintains its position. The pressure piece itself can consist of a sliding pin or a pressure roller. The adjusting device for the articulated axis of the spring-loaded lever, consisting of two intersecting elongated hole guides, permits simple adjustment that is adapted to the desired actuating characteristic.

According to another embodiment, it is provided that the locking member consists of a spring-loaded block with a thrust piece sliding on a control cam, which is supported on the one hand on a hinge pin and on the other hand on the base plate or an intermediate plate fastened to it in such a way that the thrust piece is in the closed position maintains relative position to the control curve. A correspondingly shaped block, which is preferably made of plastic, can be inserted into the hinge without special guides having to be provided on the hinge arm, the base plate or the intermediate plate. The block is expediently supported on the one hand with an elongated hole guide on an articulated axis and on the other hand with an inclined surface on edges of the base plate or intermediate plate forming guide curves or guides. The block is expediently supported on the hinge axis and a straight guide of the base plate or intermediate plate by wedge-shaped guides or surfaces.

According to the invention, the locking member is guided by guides or support surfaces provided on the hinge arm and a fitting part firmly connected to the supporting wall so that it can be pivoted and / or pivoted in such a way that when the hinge arm is pivoted to adjust the side of the door, its relative position to the control curve of the by the locking member applied lever does not change. The locking member is not firmly connected to the hinge arm, but can be forcibly moved by guides and / or gear members with it in such a way that it compensates for the pivoting of the articulated lever, which corresponds to a slight door opening due to the side adjustment of the door.

It is essential that the guided movement of the locking member not by pivoting the articulated lever, but only by the pivoting of the hinge arm relative to the base plate is carried out in such a way that a certain lateral adjustment of the door or pivoting of the hinge arm corresponds to a position of the locking member in the hinge arm area which is adapted by the guides or transmission members and which corresponds to the effect of the closing torque generated by the locking member on the Leaves door unchanged. For this reason, the guides for the locking member are arranged such that it performs approximately the same pivoting about the articulation axis of the articulated lever provided with the control cam during lateral adjustment relative to the hinge arm, which corresponds to a slight pivoting of the articulated lever in the sense of a slight door opening, so that the support point of the contact surface of the locking member on the control curve of the articulated lever remains unchanged. In the hinge according to the invention, the locking member can therefore be moved in two mutually independent ways, namely once by the control curve of the articulated lever, as a result of which it exerts a moment in the closing direction shortly before the closed position, and on the other hand by guides or gear members when pivoting the hinge arm, which makes it light Compensates pivoting of the articulated lever in the sense of a slight door opening, so that the closing angle range over which the closing torque is effective remains unchanged. The first movement depends solely on the joint system. The second requires the arrangement of guides, support surfaces or gear members for the locking member, which are arranged between the hinge arm and a fitting part firmly connected to the supporting wall. Although this fixed fitting part could consist directly of the base plate, it is advantageous for reasons of easier assembly to provide the hinge arm in a manner known per se with an intermediate plate which forms a fixed hinge part in the assembled state.

According to a preferred embodiment, the locking member between the hinge arm and the intermediate plate in one position stored, which is changed by guides arranged on these fittings in a manner adapted to the relative position of these fittings. This change is independent of the locking system selected in each case, since the locking system only has the function of transmitting a locking torque to the articulated lever. The locking member should therefore press on the control cam of the articulated lever via a specific support point, the compressive force generating the closing force being able to be generated in any known manner. The locking member itself can therefore consist of a spring-loaded pressure part or directly itself from a compression spring.

The hinge shown in Figures 1 to 7 consists of a hinge arm 1 with a U-shaped profile, which is articulated via two links 2, 3 with a hinge cup 4 forming the pivotable hinge part. The hinge arm 1 is fastened on an intermediate plate 5 with a U-shaped profile, which in turn is fastened by means of a fastening screw 6 to a base 7 of the base plate 8 which is raised like a base. The intermediate plate 5 has in the rear end region of its legs 10 which are angled away from the web part 9 and which project outwardly projecting pins 11 which are formed by corresponding impressions in the blank from which the intermediate plate 5 is bent. The outwardly projecting pins 11 engage in free-running, slot-like guide slots 12 in the side legs 13 of the hinge arm 1. The intermediate plate 5 is provided on the joint-side end of its web part with an slot-like recess 14, in which the part provided with an annular groove 15 Set screw 16 is slidably mounted longitudinally, which is screwed into a threaded bore of the web part 17 of the hinge arm 1 provided with a flange. Between the legs 13 of the hinge arm 1, a bolt 18 is held in the front area thereof, which extends through parallel, oblique elongated holes 19 in the legs 10 of the intermediate plate 5. If the hinge arm 1 is thus pivoted between its position shown in FIG. 1 into the position shown in FIG. 2 for the lateral adjustment of the door 20 by actuating the adjusting screw 16, the bolt 18 slides from its lower position shown in FIG. 1 into the position shown in FIG 2 visible upper position in the elongated hole 19, so that the pivoting movement for side adjustment of the door 20 is superimposed on a translatory movement of the hinge arm directed to the left in the drawing, so that the joint remains constant during this adjusting movement. In this respect, the structure of the hinge corresponds to the hinge known from DE-PS 34 42 421, to which reference can be made for a more detailed illustration.

When the hinge arm 1 is adjusted between the position shown in FIG. 1 and the position shown in FIG. 2, the door is pivoted in the opening direction by the angle alpha, which is shown in FIG. 1 between the door shown in full lines and the dash-dotted line Representation that corresponds to the door position in Fig. 2 can be seen. In the pivoted-out position of the hinge arm 1 shown in FIG. 2, which corresponds to the greatest possible lateral adjustment of the door 20, the door 20 assumes an obtuse-angled position to the hinge arm 1, this obtuse angle beta being shown in FIGS. 1 and 2.

The hinge shown in FIGS. 1 to 7 is additionally provided with a locking device, which moves the door into a small angular range before the final closed position Presses the closed position. This locking device consists of a forked lever 22, the forked legs 23 of which are connected to one another by a lower web part 24, and which are pivotably mounted on bolts 39 which pass through a bearing bore 25 of the legs 23, the bolt 39 in obliquely elongated slots 27 in the legs 13 of the hinge arm 1 is guided and also penetrates obliquely extending elongated holes 28 in the front regions of the legs 10 of the intermediate plate 5, which run approximately parallel to the elongated holes 19. A preloaded compression spring 30 is clamped between the web part 24 of the lever 22 and the web part 17 of the hinge arm 1 in the manner shown in FIG. 2. The cranked legs 23 of the lever 22 in their front area in the manner shown in FIG. 4 carry a bolt 26 in bores, which forms the pressure piece of the locking device. The bolt 26 interacts with a control cam 32 which is formed on the hinge arm end of the link 2. The handlebar 2 consists of two mutually parallel levers 2 'and 2'', as can be seen from FIG. 10. The two levers 2 'and 2''are bent in mirror image to one another, their ends, which are at a greater distance from one another, being mounted on the articulated bolt 34 fastened between the legs of the hinge arm. As can be seen in particular from FIG. 1, the control cam has a sector-like section 35 which is concentric with the hinge axis 34 and merges via a rounded edge 36 into a section 37 which closely approximates the hinge axis 34. As can be seen from FIG. 1, the bolt 26 as a pressure piece has left the concentric section 35 of the control cam in the closed position and has just stepped onto the section 37 approaching the hinge pin 34 via the rounded end region 36. The push pin 26 thus presses the door into its closed position via a lever arm formed by the control disk 32 with a corresponding closing moment and holds it in this position.

From Fig. 1 it is now readily apparent that the pressure pin 26 would come across the concentric curve area 35 with the falling curve area 37 of the control curve, rounded edge on the concentric curve area if the door 20 by the angle alpha shown in dash-dotted lines , slightly open position would be pivoted. However, if this slightly open position of the door is the position that it would assume after its side adjustment in FIG. 2, the closing device could still exert no or only a slight closing moment in the closing area on the door.

In order to ensure that the closing device still exerts the same closing torque on the articulated lever even when the door is adjusted from the side, as shown in FIG. 2, it is provided in the door according to the invention that the pivot 39 of the hinge arm 1 also the bearing pin 39 of the lever 22 in one Is adjusted that the pressure pin 26 assumes the same relative position to the control cam 35 with each side adjustment of the door in the closed position. The adjustment shown in FIG. 7 takes place between the two end positions of the hinge arm shown in FIG. 1 by the fact that the hinge pin 39 supporting the pressure lever 23 rests both in the mutually parallel elongated holes 27 in the legs 13 of the hinge arm 1 and in the mutually parallel ones Elongated holes 28 is slidably guided in the legs 10 of the intermediate plate 9. As can be seen from FIG. 7, the center lines of the elongated holes 27 and 28 intersect. If the hinge arm 1 is pivoted between its position 17 shown in full lines in FIG. 7 and the position 17 ′ shown in broken lines, the hinge pin 39 moves by moving from the lower position in the elongated hole 28 to its upper position and from the upper position in the elongated hole 27 in the lower position shown in FIG. 7 Position in the slot 27 '. The articulation pin 39 executes a pivoting angle delta about the articulation axis 34 due to its displacement into the position 39 '. This pivoting compensates for the displacement of the pressure piece 26 of the closed position, which this would carry out in itself by the pivoting movement of the hinge arm. From Fig. 7 it can be seen that in the two extreme settings of the hinge arm, which corresponds to the positions shown in Figures 1 and 2, in the closed position the pressure bolts 26 and 26 'always the same angle gamma and gamma' to the center 40 of the Include curvature 36, which connects the concentric curve area 35 with the steeply falling curve piece 37. From Fig. 7 it can thus be seen that by the adjustment of the pivot pin 39 of the pressure lever 22 through the cam guides 27, 28 with each adjustment of the hinge arm, the hinge axis of the pressure lever is pivoted such that the pressure pin 26 has its relative position to the control cam 35, 36 , 37 does not change.

The second exemplary embodiment of the invention according to FIGS. 8 to 13 differs from that according to FIGS. 1 to 7 in that the pressure lever 22 is replaced by a block 43 carrying the pressure pin 42. The exemplary embodiment according to FIGS. 8 to 13 is therefore only described insofar as it differs from the exemplary embodiment according to FIGS. 1 to 7 with regard to the block 43 and its adjustment by pivoting the hinge arm 1.

The shape of the block 43 is best seen in FIGS. 11 and 12. The block consists of a round body 44 which is approximately triangular in side view and which is provided with a stepped extension 45. Between the round body 44 and the extension 45, a free-running, slot-like recess 46 is provided. In its upper area, the extension 45 has a transverse bore 47, in which the pressure pin 42 is held. Furthermore, the block is provided on both sides with triangular projections 48, the rear sides 49 of which form straight guide tracks which run at an angle to the inner guide track 50 delimiting the slot-like recess 46. The block 43 is provided with a blind hole 52 on its upper side.

As can be seen from FIGS. 8 and 9, the block 43 is inserted between the hinge pin 34 of the inner link 2 and the front edges of the front ends of the legs 10 of the intermediate plate 5 in such a way that its guideways 49 and 50 lie on the edges of the legs and support the bolt 34. The guideways 49 and 50 cross each other in the manner shown in FIG. 11, so that when the hinge arm 1 is moved, the block 43 executes a movement shown in FIG directional, translational movement is superimposed. As a result, when the hinge arm is adjusted, the block 43 executes a movement which changes the position of the pressure bolt in such a way that it in turn maintains its relative position to the control cam 35, 36, 37 in all pivot positions. From Fig. 13 it can be seen that after pivoting the hinge arm the angle gamma or gamma 'between the pressure pin 42 and the control cam does not change in the closed position.

From Fig. 10 it can be seen that the block 43 with its extension 45 engages over the hinge pin 34 in such a way that it engages between the hinge arm-side and outwardly bent parts of the mirror-image control arm 2, 2 '.

The block 43 has the advantage over the pressure lever 22 that no additional slot guides have to be provided in the legs of the hinge arm and the intermediate plate.
