Abstract

The invention relates to a hinge (1) comprising a side part (2) that can be fastened to a wall and a hinge part (3) that can be pivoted relative to the side part (2), at which hinge part a door can be attached, and comprising a linear damper (10) arranged in the side part (3) with a housing (11, 11') and a piston rod (12). The housing (11, 11') of the linear damper (10) is non-rotatably fixed in the side part (2) on at least one journal (8, 9), on which a lever (4, 5) for pivotable mounting of the hinge part (3) is mounted.

Description

85835872 1 Hinge The present invention relates to a hinge having a side part which can be fastened to a wall and a hinge part which can be pivoted relative to the side part and to which a door can be fixed, and having a linear damper arranged in the side part with a housing and a piston rod which is pretensioned by a spring in a direction away from the housing. DE 20 2006 003 196 U discloses a furniture hinge in which a hinge part is pivotally mounted on a side part by means of a support lever and a guide lever. The guide lever is equipped with an extension arm on which a linear damper with a housing and a piston rod that is displaceable relative to the housing is pivotably mounted. Such a linear damper is well suited for damping a closing movement, but there is the problem that by pivoting the linear damper the required installation space in the side part is large. It is therefore the object of the present invention to create a hinge which, in a particularly compact design, allows at least one closing movement to be damped. In the case of the hinge according to the invention, a housing of the linear damper is non-rotatably fixed in the side part and fastened to a holder, wherein the holder is fixed to at least one axis on which a lever for pivoting the hinge part is rotatably mounted. As a result, the axis can be used both to support the hinge part and to fix the linear damper. On the one hand, this leads to a reduction in the number of components, and on the other hand, it allows the linear damper to be fixed in the immediate vicinity of the lever, so that the linear damper requires comparatively little installation space. The holder can be fixed on two axes or, in an alternative embodiment, the holder can be fixed in a non-rotatable manner via at least one axis and with one body edge of the holder resting against the side part. The holder preferably has a U-shaped shaped part having two legs with openings in which at least one axis is inserted. Particularly preferably, the at least one axis has a polygonal area which approximately corresponds to at least one opening of a leg of the holder. As a result, the linear damper can be easily mounted by pushing the axis through. Date Re9ue/Date Received 2024-02-08 2 The linear damper preferably comprises a pot-shaped housing, which is integrally designed with the holder. Alternatively, the housing of the linear damper can also be pot-shaped and have at least one step projecting radially outwards on the side facing away from the base so that the housing can be inserted into an opening in the holder. Irrespective of whether the housing and the holder are one or more components, the housing preferably contains a linearly displaceable piston to which the piston rod is fixed. In a further embodiment, a control cam is formed on one of the levers, which compresses the linear damper during a closing movement of the hinge shortly before reaching a closing position and during an opening movement shortly before reaching the maximum opening position. As a result, the linear damper can be used for both closing and opening damping. As an option, the opening damping can also be dispensed with. The control cam is preferably formed on at least one curved web of the lever or hinge part and slides along a pin which rests against the linear damper. The pin can be guided linearly in an elongated hole of the holder, so that the pin is moved linearly via the control cam and the linear damper is pressed together accordingly or can be moved apart. It is also possible to actuate the damper directly through the cam. For a particularly compact design, the stroke length of the linear damper is designed to be less than 5 mm; in particular, the stroke can be between 3 mm and 4.2 mm. The length of the linear damper is preferably less than 20 mm, in particular less than 18 mm, so that the linear damper only occupies a small construction volume in the side part. The invention is explained in more detail below using several embodiment examples with reference to the attached drawings, wherein: Fig. 1 Fig. 2 Figs. 3 and 4 Fig. 5 shows a perspective exploded view of a hinge according to the invention; shows a sectional side view of the hinge of Fig. 1 in a closed position; show two views of the hinge of Fig. 2 in middle opening positions; shows a view of the hinge of Fig. 2 in a maximum opening position; Fig. 6 Fig. 7 Fig. 8A Fig. 8B Fig. 9 Fig. 10 Fig. 11 Fig. 12 3 shows a diagram for illustrating the longitudinal extension of the damper in relation to the opening position of the hinge part; shows a partially sectional perspective view of the hinge of Fig. 1 with mounted holder; shows a top view of the hinge with section through the holder with linear damper; shows a detailed view of the section from Fig. SA on holder and linear damper; shows a perspective view of the linear damper fixed to the holder; shows a top view of the holder of Fig. 9; shows a perspective view of a modified embodiment exampl
