The invention concerns a cabinet fitting, in particular a hinge, with integrated braking and damping device, including a fastenable hinge arm on a cabinet component and a fastenable hinge cup on another movable cabinet component that is connected by at least one articulated lever with the hinge arm. The invention is characterized by the driver plate, which can slide, is held in the hinge cup and can be operated directly or indirectly by the articulated lever and has held in the hinge cup at least one pivoting or swiveling brake plate moves turning, so that the brake plate has at least one brake surface that glides on at least one corresponding, fixed brake surface or, on one opposite the first brake surface, a second movable brake surface.

The invention concerns a cabinet fitting, in particular a cabinet hinge, with a braking and damping device, according to the characterizing clause of the independent patent claim 1.
Damping and braking devices are well known in different variations in the present technology and are used in assorted areas of application. There are currently damping elements for movable cabinet parts in the form of simple buffers on the market. Such buffers are very well suited for moderating noise, but are, however, not suitable for diminishing the kinetic energy of the movable cabinet parts in the amount necessary. Another further development of a ductile buffer that is integrated in a hinge is described in DE-OS 27 08 545. Here, a flexible damping element is located between the hinge links of a cabinet hinge and deforms shortly before reaching the hinge's open position. A similar damping element for cabinet hinges is shown by AT-PS 349 931. Here, there is a flexible attenuator between the hinge arm and hinge cup on which the hinge arm is supported in a cushioned and absorptive manner.
Also, among other things, hydraulic or pneumatic dampers are well known, which have a piston-cylinder system with two working chambers, between which a liquid or gaseous medium flows and which then causes a braking or damping effect. Such dampers have a high static friction, due to the piston rod and piston sealing, which sets a reduction of the borders of the pump size. Furthermore, they are complex and expensive and are not suitable, therefore, as integrated dampers in cabinet fittings.
Shown:
FIG. 1: an overview of the cabinet hinge, according to the invention, in a first embodiment;
FIG. 2: a side section cut through the cabinet hinge, according to FIG. 1, in a half-closed position;
FIGS. 1 and 2 show a cabinet hinge (1), by means of which a cabinet component (for example, a cabinet door), can be fastened movable to a cabinet body. The cabinet door can be opened, thereby, within the range of an opening angle, so that closes, within the range of a closing angle, automatically by the cabinet hinge (1). This automatic closing movement applies to the braking and damping, since the cabinet door would, otherwise, impact hard on the cabinet body.
The cabinet hinge (1) includes a hinge arm (2) that is fastened to the cabinet door and that is connected swiveling by an outer and an inner articulated lever (3, 4) with a hinge cup (5). The hinge cup is locked by a base plate (6) and contains the invention-related braking and damping device (7), which produces the necessary braking action when the cabinet hinge is closed.
As shown in FIG. 3, there is a driver plate (8) in the cup base area, which is held linearly movable in arrow direction (9). The moving or shifting results from the articulated hinge's (3,4) movement in arrow direction (10), so that a link edge (11) of the inner articulated lever (4) activates a driver nose (12) of the driver plate (8). Underneath the driver plate (8) there are two, preferably circular, brake plates (15,16), into which a corresponding driver pin (13,14) of the driver plate (8) always engages.
