The present invention relates to a furniture fitting for moving a movable furniture part, comprising:

• a carrier,
• at least one furniture fitting part, which is movably mounted relative to the support,
• a spring device for applying force to the furniture fitting part,
• - A transmission mechanism for transmitting a force from the spring device to the furniture fitting part, wherein the transmission mechanism has a arranged on the support of the furniture fitting adjusting contour and loaded by the spring device pressure piece, wherein the pressure piece is movable in a movement of the furniture fitting part along the control contour.

Furthermore, the invention relates to an arrangement with a movably mounted furniture part and with a furniture fitting of the type to be described.

A furniture fitting in the form of a furniture hinge is for example in the AT 413 728 B shown by the applicant. The furniture hinge has a locking mechanism with a locking contour formed on the hinge arm, wherein in a hinge movement acted upon by a spring pressure piece along the control contour can be moved. The control contour is formed integrally with the hinge arm. It has been shown that high wear is caused due to the high loads between the pressure part and the setting contour. A smooth surface of the control contour and / or the pressure piece is also a necessary condition, because any unevenness of these components during the opening and closing of the movable furniture part for a user negatively noticeable.

The DE 37 08 703 A1 shows a furniture hinge with a hinge arm and a hinge pot, which is pivotally connected via two hinge levers with the hinge arm. On one of the toggle lever loaded by a coil spring pressure piece is pivotally mounted with a control cam, wherein the control cam cooperates in the closing movement of the hinge with a plate of spring steel. The spring steel plate is flat and abuts an inside of the hinge arm, protecting the hinge arm from premature wear.

Object of the present invention is to provide a furniture fitting of the type mentioned above while avoiding the above drawback.

This is achieved by the features of claim 1. Further advantageous embodiments of the invention are specified in the dependent subclaims.

According to the invention, it is thus provided that at least that region of the adjusting contour and / or at least that region of the pressure piece which come into contact with one another during the movement of the furniture fitting part is or are made of a sintered material.

Thus, that region of the control contour or that region of the pressure piece which cooperate with one another during the movement of the furniture fitting part is formed from a sintered and thus higher-value or more abrasion-resistant material. The improvement of these mechanical properties can only take place in that region of the setting contour and / or the pressure piece in which this is actually necessary, so that therefore not the entire carrier and / or the pressure piece must be made of a sintered material. In this way, on the one hand the furniture fitting can be produced inexpensively, on the other hand, the abrasion resistance of the control contour and / or the pressure piece can be improved.

As the sintered material, sintered metal powder and / or sintered non-metallic material (for example, plastic and / or ceramic) may be used.

The use of sintered material has the advantage that a high dimensional accuracy and a high surface quality of components can be achieved by sintering. The surface of sintered bodies is characterized - in comparison solid materials - by a very low roughness, so that the running properties of the displaced on the control cam pressure piece can be improved. It is also possible that the interconnected micropores of the sintered material are filled with a lubricating oil, whereby a self-lubrication between the control contour and the pressure piece is formed, without this an additional lubricant is required.

According to one embodiment, a sliding layer can be sintered directly onto the carrier and / or onto the pressure piece, so that at least that region of the setting contour and / or at least that region of the pressure piece which come into contact with one another during the movement of the furniture fitting part together with the carrier and / or is integrally formed together with the pressure piece or are.

Alternatively, it is possible for at least that region of the setting contour which comes into contact with the pressure piece during the movement of the furniture fitting part to be formed as a contour element separate from the carrier. At this Kontjud or on the carrier, a fastening device may be provided, through which the contour part can be fastened to the carrier. This attachment may be detachable, so that the contour part can be replaced in case of premature wear or replaced by a Kontjudgment with differently shaped control curve. The fastening device can be designed as a latching device (that is to say a form-fitting connection with a defined end position of the components to be connected). It can be provided that the latching device has at least one latching element arranged on the contour element, which can be latched, preferably releasably, with a latching recess arranged on the carrier. In mechanical reversal, it is also possible that the locking element on the carrier and the detent recess are formed on the contours.

According to one embodiment, it may be provided that the furniture fitting is designed as a furniture hinge, wherein the furniture fitting part is a movably mounted articulated lever of the furniture hinge.

According to a further embodiment it can be provided that the furniture fitting is designed as an actuator for furniture flaps, wherein the furniture fitting part is a pivotally mounted actuating arm for moving a furniture flap.

The arrangement according to the invention is characterized by a movably mounted furniture part with a furniture fitting of the type described.
