Abstract

A hinge includes an attachment part to fasten the hinge to a fixed furniture part, an articulated lever, and a hinge cup pivotably arranged on the attachment part via the articulated lever. The articulated lever is mounted with the hinge cup via a hinge pin, and the hinge cup can be fastened to a movable furniture part. A damping device dampens a relative movement between the attachment part and the hinge cup between an open position and a closed position of the hinge, and the damping device has a linear damper with a piston and a translationally movable piston rod. The linear damper is arranged at least in certain regions outside the hinge cup, and the translationally movable actuating element can actuate the damping device. The actuating element is arranged for the most part within the hinge cup.

Description

The present application is a continuation of International Application PCT/EP2022/082779 filed on Nov. 22, 2022. Thus, all of the subject matter of International Application PCT/EP2022/082779 is incorporated herein by reference. BACKGROUND OF THE INVENTION The invention relates to a hinge, in particular a furniture hinge, comprising an attachment part with which the hinge can be fastened to a stationary furniture part, at least one articulated lever, and a hinge cup which is or can be pivotably arranged on the attachment part via the at least one articulated lever. The at least one articulated lever with the hinge cup is mounted via at least one hinge pin, and the hinge cup can be fastened to a movable furniture part. At least one damping device is provided for damping a relative movement between the attachment part and the hinge cup between an open position and a closed position of the hinge, and the at least one damping device has a linear damper with a piston and a translationally movable piston rod. The linear damper is arranged at least in areas, preferably completely, outside the hinge cup. At least one translationally movable actuating element, which is preferably one-piece and/or separate from the at least one articulated lever, particularly preferably spatially at least in the open position, is provided for actuating the at least one damping device. Such a hinge is already known from the document WO 2016/102215 A1, in which a linear damper with a slide as actuating element can be fastened to the outside of a hinge cup, and the articulated lever contacts the linearly movable slide through a hinge cup opening in order to actuate the linear damper. The slide is clipped onto the outside of the hinge cup together with the linear damper via a housing. A disadvantage of the state of the art is that, due to the transfer of the rotational movement of the articulated lever to the slide in the outside area of the hinge, a force distribution on the slide is unfavorable as a force vector induced by the rotation of the articulated lever points orthogonally to the piston rod in the direction of the housing, which is not joined to the hinge cup in a material-bonding manner. As a result, an undesired tilting of the slide between the hinge cup and the housing is promoted and causes an anharmonic damping movement, a high wear of the component parts involved in the damping, and an unfavorable transmission of force onto the linear damper. In addition, the articulated lever has to be very precisely adapted to the slide in terms of geometry and tolerances in order to effect a damping of the hinge in the desired movement range of the articulated lever when it sticks out of the hinge cup. A large hinge cup opening is also required, as a result of which dirt particles, which reduce the functionality of the hinge and its service life, can enter the hinge cup. In addition, additional work steps are required in the installation of the hinge in terms of the preinstallation of the slide and the housing on the hinge cup, which is to be carried out by trained personnel in order to be able to guarantee proper usage of the hinge. An installation space is also increased by the slide being supported on the outside by the housing. Furthermore, a conversion of the rotational movement to the linear movement of the slide is limited by the geometry and location of the hinge cup opening. SUMMARY OF THE INVENTION The objective technical problem of the present invention is therefore to specify a hinge that is improved compared with the state of the art, in which the disadvantages of the state of the art are at least partially remedied, and which provides a compact design and/or a particularly favorable transfer of a rotational movement of the at least one articulated lever to the piston rod. According to the invention, the at least one actuating element is arranged predominantly, preferably completely, inside the hinge cup. This makes it possible first of all that a force effect transmitted in the course of the rotational movement of the at least one articulated lever can act on the at least one actuating element in the direction of a hinge cup base, more specifically the hinge cup base can act as a counter bearing for the at least one actuating element in the course of a damping movement. The arrangement of the at least one actuating element predominantly inside the hinge cup means in this context that at least 50%, preferably at least 70%, particularly preferably at least 90%, of the volume of the at least one actuating element is arranged inside the hinge cup. Added to this is the positive property that the kinematics for actuating the piston rod is integrated in the hinge cup, with the result that a height of the hinge cup and/or a diameter of the hinge cup can be formed particularly small, with the result that a large range of application in pieces of furniture, windows, doors or the like—for example with narrow movable parts or small fa
