Description

The invention relates to a furniture hinge with a on a base plate mounted hinge arm, with U-shaped cross-section od by means of articulated lever. Like. With a door-side stop member, such as a hinge cup is connected, wherein the Base plate in assembled state with a mounting surface on a furniture sidewall rests and in the hinge arm a Fugenverstellschraube is screwed in a Intermediate piece rotatable, but anchored immovable in the axial direction and with the the position of the hinge arm in a direction perpendicular to the mounting surface of the base plate Level for lateral adjustment of a door is changeable, with a guide provided is that guides the hinge arm in the longitudinal direction and another guide through which the hinge arm with a rotation of the joint adjustment screw both parallel to Mounting surface of the base plate moved as well as in a perpendicular to this Mounting surface aligned plane is pivoted, and another intermediate piece is provided, which is rigidly held on the base plate in the longitudinal direction of the hinge arm is.

In general, in hinges of the hinge arm by means of a clamping screw on the Base plate or an intermediate piece attached. Thus an adjustment of the hinge arm in the depth of the furniture is possible, this clamping screw protrudes through a slot in the Hinge arm. The adjustment of the hinge arm in the depth of the furniture is determined by the length of this slot.

Furthermore, in general, an adjustment for the position of the hinge arm is relative to the base plate in the direction of the furniture joint, i. perpendicular to the side wall of the furniture intended. This adjustment is achieved by a so-called joint adjustment screw, which is stored in a nut thread of the hinge arm and with her head in one Recess of the base plate or the intermediate piece is held.

In recent times, the hinge arms are generally not directly on the base plate stored, but indirectly via an intermediate piece that extends between the hinge arm and the base plate is located.

Examples of such a hinge are shown in WO 86/02402. This kind of Hinge makes it possible, when assembling the furniture, d. H. when hanging the furniture door the hinge arm together with the attached intermediate piece quickly and without tools to a base plate, which is attached to a furniture side wall to anchor.

Nevertheless, then, if necessary, the position of the hinge arm relative to Base plate (and intermediate piece) after loosening a clamping screw through the joint adjustment screw respectively.

WO 97/22773 shows a similar hinge. The hinge arm is by means of a Intermediate piece attached to the base plate. The adjustment of the hinge arm takes place in the direction perpendicular to the furniture side wall by means of a Fugenverstellschraube and in the Direction parallel to the furniture side wall by means of a spiral disk. The intermediate piece is in the base plate suspended and by means of a spring-loaded rocker arm on this anchored.

It has been found to be disadvantageous that in a side adjustment of the door, i. in the Joint adjustment, the hinge arm by turning the joint adjustment screw is pivoted. Thus, the hinge arm relative to the door an obtuse-angled position occupy, which corresponds to a slight door opening, although the door on the carcass parts is present and in its closed position. A lateral adjustment of the Hinge poor with respect to the furniture side wall can therefore cause the door either lifted to far from the front edge of the furniture side wall or at this stuck. It can thereby also the function of a built-in hinge locking device be affected.

In these hinges, it is therefore necessary, after each side adjustment of the door or of the hinge arm, the position of the hinge arm on the base plate in the direction to correct the depth of the furniture. Such an attitude is cumbersome and relative time-consuming.

From EP 0 168 731 B a hinge is known in which a guide for the hinge arm is provided, which causes them in a lateral adjustment of the position of the hinge arm this is also placed in the depth of the furniture on the base plate. After Depth adjustment of the hinge arm must this in the spacer by means of a clamping screw be clamped. The base plate is made in two parts. In this Hinge can be a specific hinge arm only on an associated base plate anchored.

From DE 38 41 405 A, a hinge is also known in which a guide for the Schamierarm is provided, which causes, in a lateral adjustment of the position of the This is also shifted in the depth of the furniture on the base plate. The Base plate is formed in two parts and the actual depth adjustment of the Schamierarmes done by loosening a clamping screw and moving the upper Part of the base plate, optionally together with the intermediate piece and the Hinge arm on the lower part of the base plate. The disadvantage is to be considered that Such a hinge arm with the spacer only on this very special Base plate can be mounted.

The object of the invention is to a hinge of the type mentioned in order to improve that the hinge arm are anchored without tools on a base plate can, which is also used in other hinges, for example, on a Base plate which is used in a hinge according to WO 86/02402.

The object of the invention is achieved in that before mounting the Schamierarms mounted on the base plate both intermediate pieces in the hinge arm are, one of which, if the hinge arm is anchored to the base plate, with a manually actuated spring-loaded latch part, preferably a rocker arm on the Base plate is locked while the second intermediate piece on the first intermediate piece is slidably mounted in the direction of the depth of the furniture.

Advantageously, it is provided that the two intermediate pieces have a U-shaped cross section and are pushed together.

An embodiment of the invention provides that in which rigidly on the base plate anchored intermediate piece a parallel to the axis of rotation of the hinge aligned bolt stores, by both guide slots in the side bars of the second intermediate piece as well as by guide slots in the side webs of the hinge arm protrudes.

In a further embodiment of the invention it is provided that at the central web of the Hinge-poor an inwardly projecting guide tab is formed in a Slit is guided in one of the intermediate pieces.

A further embodiment of the invention provides that at least one Pivoting lever is provided, which at one end to an intermediate piece and the other End is articulated rotatably on the hinge arm and when turning the Joint adjustment screw is pivoted.
