Hinge for furniture or domestic appliances

Abstract

A hinge comprises a hinge part, which can be secured on a door of the shutter and is mounted on a side part such that it can be pivoted via a carrying lever and a guide lever, also comprises at least one spring, by means of which the hinge part, in a self-retracting region of the hinge, is prestressed into a closed position, and further comprises a linear damper with a piston rod, which can be moved relative to a damper housing and is intended for damping a closing and/or opening movement of the hinge part, wherein a deflecting element is provided, said deflecting element being mounted on the side part such that it can be rotated about an axis and being arranged between the damper and the guide lever so that, during a closing movement of the hinge part, it moves the damper in order to generate a damping force, wherein, during an opening movement of the hinge part, the deflecting element moves the damper in order to generate a damping force before the fully open position of the hinge part has been reached. This makes it possible to avoid hard impact of a door in the opening direction.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) FIG. 1 shows an item of furniture having two hinges according to the present disclosure,

(2) FIGS. 2A and 2B show two views of a hinge from FIG. 1, and

(3) FIG. 3 shows a detailed view of the hinge from FIG. 2.

DETAILED DESCRIPTION OF THE DRAWINGS

(4) An item of furniture 1 comprises a cabinet-shaped furniture body 2, on which a door 3 is mounted so it is pivotable. Two hinges 4 are provided for this purpose on a side wall of the furniture body 2.

(5) Each hinge 4 comprises a side part 5, which is fixed via a mounting plate 6 on the furniture body 2. A hinge part 7 is mounted so it is pivotable on the side part 5 via two spaced-apart guide levers 8. The pivotable door 3 is held on the hinge part 7.

(6) One of the hinges 4 is shown in detail in FIGS. 2A and 2B. One of the guide levers 8 is mounted so it is rotatable about an axis 9 on the side part 5. On the opposite side, the guide lever 8 is arranged so it is rotatable on the hinge part 7, wherein a cup-shaped receptacle 10, in which a rotatable actuating element 11 is arranged, is formed in the hinge part 7. The actuating element 11 is arranged on a holder 12, which has a rotation damper. The actuating element 11 is mounted so it is rotatable in this case and is pre-tensioned in a starting position. If the hinge 4 is moved into a closed position, a first activation region 18 on the actuating element 11 engages with a contact region 22 on the guide lever 8 and can slide along this contact region 22, so that the actuating element 11 is rotated and therefore the closing movement is damped and/or decelerated. After completed damping and opening of the door 3, the actuating element 11 is pre-tensioned in a starting position again via a spring, to be movable for the next damping stroke.

(7) Furthermore, a switch 13 is provided on the holder 12, by means of which the restoring stroke of the actuating element 11 is settable in a known manner.

(8) In addition to the closing damping, an opening damping can also be performed on the hinge 4, wherein a second activation region 20 is provided for this purpose on the actuating element 11, as shown in FIG. 3. The actuating element 11 is essentially designed as a two-armed lever and has a first arm 19, on which the first activation region 18 is provided. Furthermore, a second arm 14 is provided, which is aligned offset by more than 90 in relation to the first arm 19 with respect to an axis of rotation 17 of actuating element 11 and on which the second activation region 20 is provided.

(9) The guide lever 8 is mounted so it is rotatable about an axis 16 on the hinge part 7 and has the first contact region 22 on the region between the axis 16 and the axis 9, to move the actuating element 11 during a closing movement. Furthermore, a cantilever 15 is formed on the guide lever 8 adjacent to the axis 16 on the hinge part 7, which cantilever protrudes at an angle from the guide lever 8 and on which a second contact region 21 is provided, which engages with the second activation region 20 on the actuating element 11 during an opening movement. If the hinge is now moved further in the opening direction, the guide lever 8 is pivoted into the dashed position 8, wherein the actuating element 11 is pivoted counterclockwise in FIG. 3, as shown by the dashed lines. The first arm 19 and the second arm 14 are therefore also pivoted about the axis 17 when the hinge 4 is arranged in a predetermined open position. Both a closing damping and also an opening damping are thus caused using the same damping device.

(10) The opening damping may take place at least in an angle range of at least 10 before the maximally open position. In an embodiment, the opening damping can begin in a range between 20 and 30 before the maximally open position. If the door 3 is moved back in the closing direction after opening damping, firstly the cantilever 15 disengages from the second arm 14 of the actuating element 11, so that the actuating element 11 is moved by the force of a spring back into the starting position. The first contact region 22 of the guide lever 8 only subsequently then engages with the first activation region 18 on the first arm 19.

(11) In the illustrated embodiment, a rotation damper is used for damping the movement of the actuating element 11. Of course, it is also possible to use a friction damper or a linear damper instead of a rotation damper.

(12) In addition, the damping device can have an adjustment mechanism, to be able to set the damping stroke of the actuating element 11.
