Description

Furniture hinge (4)

The invention relates to a furniture hinge, which has a mounting plate and a hinge. The mounting plate is provided with a side portion. The hinge plate is pivotally held on the side portion via a carrying lever and a guiding lever. There is a bumper to cushion the movement of the hinge relative to the side.

A furniture hinge is disclosed in the European patent EP 155 5372, in which a hinge portion is pivotally supported on one side. For this purpose, a carrying lever and a guiding lever are provided which pivot the hinge portion fastened to a movable furniture part, for example a furniture door, in the form of a parallel link. In order to cushion the movement, a linear damper is provided on the side, which is connected to a projection on the guiding lever via a chain element. Therefore, a buffering action is caused when the guiding lever pivots. In this case, the coupling is designed in a rigid manner, so that the error can only be offset to a limited extent, in particular when the furniture door is aligned and the hinge portion is adjusted relative to the side or the mounting plate. In addition, the connection via the chain element is cumbersome and difficult to install.

It is an object of the present invention to provide a furniture hinge that is resilient to error cancellation and that can be easily installed.

This object is achieved by using a furniture hinge having the features of the first item of the patent application.

According to the invention, a mover is supported on the side, the mover resting on a contact surface on the bumper and causing a coupling between the bumper and the carrying lever or the guiding lever or hinge portion. In this case, the mover forms a movable intermediate element which is not firmly connected to the buffer via a shaft connection at the opposite end, but only leans against a contact surface which is directly or indirectly buffered. Connected. As such, the construction of the furniture hinge is simple because the mover is only held on a guide on the side. In addition, some error compensation can be made when installing, since force transmission is only achieved through the contact surface and there is no rigid joint.

According to a preferred embodiment of the invention, the mover is held on the side and is movable via the guiding means. Here, the mover can move in the same direction as the piston rod of the damper, so that lateral forces do not occur when the force is transmitted.

In order to limit the range of motion, the mover remains in a manner that is movable between the two stops, wherein the range of motion is designed such that the cushioning action acts as far as it is within the desired range, mostly not far in front of the closed position of the hinge.

In order to make furniture with only a few components, the mover has a one-end section that rests directly on the housing of the bumper.

In order to guide the movement of the mover, the mover can have a long hole and a plug embedded in the long hole. In addition to forming a guiding means, the long holes constitute a stop portion on the opposite side to restrict the moving path.

The mover should preferably be moved by a frame with a tip that is carried by the lever such that the pivotal movement of the carrying lever causes linear movement of the mover and the damper.

The damper should be designed in the form of a linear damper and held by a spring to pre-stress the damper so that when the hinge portion is opened, the spring presses the damper (or the housing of the damper) to a removed position. The spring exerts a smaller force on the bumper than the other spring (which pre-stresses the hinge to the closed position).

For ease of installation, the side portions can have a pivotable flap that is secured thereto, such that the bumper can be secured to the flap in a simple manner using a snap fit or other securing means.

The invention is described in detail below using an embodiment.

A metal and/or plastic furniture hinge (1) comprises a mounting plate (2) which can be fixed to a specific one, and the side plate (3) can be fixedly or adjustably arranged on the mounting plate. A pot-shaped hinge portion (4) is pivotally supported on the side portion (3), wherein a carrying lever (5) and a guiding lever (6) are provided for pivotal movement. The carrying lever (5) is pivotally connected to the hinge portion (4) via a shaft (7), and is pivotally connected to the side portion (3) via a shaft (8), and the guiding lever (6) is rotatable via a shaft (9) The support is supported on the hinge portion (4) and rotatably supported on the side portion (3) via a shaft (10), and the hinge portion (4) can be fixed to a recess of a furniture door.

A frame strip (11) is integrally formed on the carrying lever (5) for contacting a curved tip end (19) of a linearly movable mover (12). Here, the mover (12) is supported on the side portion (3) via a guiding means. To this end, a long hole (18) is hollowed out in the mover (12), and a plug (17) fixed to the side portion (3) is inserted into the long hole.

The mover (12) has an end section (13) on the side opposite the tip end (19) which acts on one end face of a housing (14) of a buffer in the side section (3). The damper is designed in the form of a linear damper with a piston rod (15) that can be moved into the housing (14). The buffer can be designed in the form of a fluid buffer or a gas buffer.

The housing (14) of the damper is held on a cover sheet (20) of the side portion (3) which is pivotable about a shaft (22) which forms a stop (21). One end of the piston rod (15) and one end of the spring (16) rest on the stop portion (21), and the spring is supported on the opposite side of the housing (14). The housing (14) is thus prestressed against the direction of the mover (12).

The furniture hinge (1) is shown in Figure 1 in an open position in which a member (e.g., a furniture door) that is coupled to the hinge portion (4) is open.

In Fig. 2, the hinge portion (4) pivots in the direction of a closed position, wherein the angle α between the illustrated position and a closed position is about 45°. When the hinge portion (4) pivotally moves, the carrying lever (5) and the guiding lever (6) also pivot, wherein the frame strip (11) carrying the lever (5) is pressed onto the moving device (12), The mover presses the piston rod (15) into the housing (16) of the bumper.

Figure 3 shows the closed position of the hinge portion (4). Here the hinge portion (4) is prestressed to a closed position via a spring, wherein the force of this spring is greater than the force of the spring (16).

When the hinge portion (4) is opened, the housing (14) of the damper is moved by the force of the spring (16) and presses the mover (12) until the plug (17) reaches the end of the long hole (18).

The mounting position of the furniture (1) is shown in Figure 4, in which the cover sheet (20) is in the open position. In this way, the damper can be fixed to the side portion (3) in a simple manner with the housing (14), the piston rod (15) and the spring (16). Here, the cover sheet is supported on the side portion (3) and is pivotable about a shaft (22).

The side portions (3) can be held in a manner movable relative to the mounting plate (2) by means of suitable adjustment means. The length of the buffer path is limited by the long hole (18), which is chosen such that the buffering material occurs only before the closed position of the hinge portion (4).

When the cover sheet (20) is open, the mover (12) can also be mounted in a particularly simple manner, the mover (2) being fixed to the side portion (3) via a shaft (13).
