Description

Furniture hinge (2)

The present invention relates to a furniture hinge having a mounting plate and a hinge portion disposed on the mounting plate, the hinge portion being held on the side portion and pivotable via a carrying lever and a guiding lever, wherein a hinge is provided The bumper buffers the movement of the hinge portion 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 in a manner of a parallel link to a hinge which is fastened to a movable furniture part, for example a furniture door. 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 in a limited manner, in particular when the furniture door is aligned and the hinge portion is adjusted relative to the side or a 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 flexible for error cancellation and that can be easily installed.

According to the invention, a lever is supported on the side which leans against a sliding surface on the bumper and causes a coupling between the bumper and the carrying lever or the guiding lever or the hinge portion. In this way, the lever constitutes an intermediate element, but it is not firmly coupled to the bumper via a shaft connection on the opposite end, but can only lean against a sliding surface that is directly or indirectly connected to the bumper. Therefore, the furniture hinge can be mounted in a simple manner, since the lever only has to be fixed to a shaft on the side, and the error can be compensated somewhat because the sliding surface is not a rigid connection.

In accordance with a preferred embodiment of the present invention, the lever is supported in a freely movable manner on the opposite side and only leans against the sliding or contact surface. In this way, the lever can be mounted irrespective of the other components and the lever only functions when the sliding surface or the contact surface pivots the lever in the desired manner.

The lever should be moved over a projection of the carrying lever or the guiding lever (which acts as a curved guide), so that when the furniture hinge pivots, the lever acts on the bumper according to the label, for example, only in the furniture hinge (or the furniture door connected to it is closed) in the range not far before. The lever should preferably be designed such that the bumper is only effective in the range of less than half of the maximum length of the pivoting path of the hinge portion, which makes the operation simpler, so that the position of the hinge portion can be reached without difficulty. Here, the hinge portion can be prestressed to the closed position by means of at least one spring, since a furniture door connected to the hinge portion can be held in the closed position.

The damper is preferably designed in the form of a linear damper and is prestressed by a spring to hold the lever so that when the hinge is opened, the spring presses the damper (or the housing of the damper) to a position where it is removed. The force exerted by the spring on the bumper is less than the force of the spring that pre-stresses the hinge to the closed position.

In order to be simple to install, the side portion may have a pivotable flap that is secured thereto. As such, the bumper can be secured to the cover sheet in a simple manner using snap means or other securing elements.

The invention is described in detail below using an embodiment. In the schema:

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

A projection (11) is formed on the guiding lever (6), facing the side portion (3), which can be mechanically coupled with a lever (12) [which is rotatable about an axis (13)], the lever (12) ) is equally supported on the side portion (3).

The lever (12) has a first leg (14) which is provided on the side of the projection (11) and has another leg (15) on the opposite side, the leg (15) facing a damper. The leg (14) is provided with a curved guiding surface (16) along which the projection (11) can slide to pivot the lever (12).

A linear damper is provided on the side portion (3) having a housing (18) and a movable piston rod (19). The buffer can be designed as a fluid buffer or a pneumatic buffer. The housing (18) of the damper is held on a pivotable cover sheet (21), and a stop is formed on the cover sheet (21). One end of the piston rod (19) rests on the stop (22), and one end of the spring (20) also rests on the stop, and the opposite side of the spring is supported on the housing (18). As such, the housing (18) is prestressed against the direction of the lever (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 opened.

In Fig. 2, the hinge portion (4) pivots in the direction of the closed position, wherein the angle ? between the position shown and the closed position is about 45[deg.]. When the hinge portion (4) is pivotally moved, the carrying lever (5) and the guiding lever (6) are also pivoted, wherein the protruding portion (11) is pivoted to lean against a contact surface (16) against the lever (12) on the leg (14).

If the hinge portion (4) is now pivoted to the closed position again, the protrusion (11) presses the lever (12) against the housing (18) of the bumper via the contact surface (16), and the buffer is compressed at this time until Up to the position shown in Figure 3. Here, the hinge can be prestressed from a closed position via a spring, wherein the spring force is greater than the force of the spring (20).

When the lever (12) is pivoted, the protrusion (11) on the contact surface (16) slides on one side, and on the other side forms a contact surface (17) on the leg (15) which is in the piston A sliding surface (24) on the housing (18) is guided along. In this way, the housing (18) only moves linearly, wherein corresponding guiding means are provided on the side portions, and the housing (18) only moves linearly.

When the hinge portion (4) is opened, the protrusion (11) slides over the sliding surface (16) on the lever (12), and the lever is pivoted by the force of the spring (20), so the housing (18) is again driven from the piston. (19) Removal.

Figure 4 shows a mounting position of the furniture hinge (1) with the flap (21) in the open position. In this way, the damper can be fastened to the side portion (3) in a simple manner with the housing (8), the piston rod (19) and the spring (20). Here, the cover sheet (21) is supported on the side portion (3) and is pivotable about a shaft (23). Here, the side portions (3) can be held in a manner movable relative to the mounting plate (2) via suitable adjustment means. When the cover flap (21) is open, the lever (12) can be mounted in a particularly simple manner, and the lever (12) is fixed to the side portion (3) via a shaft (13). Here, the shape of the lever (12) can optionally be chosen such that the damper acts only within the desired range of the pivoting movement of the hinge (4). Furthermore, if the hinge portion (4) is adjusted relative to the mounting plate (2) when the furniture door is aligned, the lever (12) can compensate for some of the error.
