Furniture hinge

The present invention relates to a furniture hinge having a mounting plate, a first hinge portion being fixed to the mounting plate via an intermediate member, and having a second hinge portion, the second hinge portion being disposed relative to the first hinge portion Pivoting and pivoting on a carrying lever and a guiding lever in the form of a parallel link, wherein the guiding lever is coupled to a damper having a piston rod, and the piston rod is movable along the same The longitudinal axis moves in a direction that extends over the first hinge portion between a shaft carrying the lever and a shaft of the guiding lever.

German Patent No. DE 37 41 712 discloses a furniture hinge in which a carrying lever and a guiding lever are provided between a furniture head and a hinge portion pivotable relative thereto, each of which is preset to open one door. motion. Here, a damper element is provided on the guide lever which is fixed to a projection of the hinge housing. Here, the piston rod of the damper moves in a direction of the projection, wherein the buffer path is shorter and the cymbal creates a compact configuration. In addition, the hinge housing is specifically designed to fit the bumper design and is not particularly useful for other hinges. In addition, the hinge housing also fits specifically into the bumper and cannot be used for other hinges. By securing the bumper to the hinge housing, lateral forces can occur which can affect the functional effectiveness of the bumper.

A damping device for a hinge is known from German Patent No. DE 201 15 250, in which a hinge is fastened to a piece of furniture, in which a cushioning element is fastened to the hinge. The cushioning element has a housing of its own and a piston rod. It is movable relative to the housing. Thus, the hinge having the damper has a large construction size, and the installation is troublesome.

International Patent WO 03/093616 refers to a multi-joint hinge in which a plurality of pivotable joint elements are provided between the two hinge portions, wherein a cushioning means is provided on a hinge portion. Here, since the structure is open, when the member moves, the person is injured, and the structure of the hinge is not suitable for use.

European Patent EP 1 555 372 refers to a hinge in which the damper extends over the entire length of the hinge arm. The height and side length of the hinge are adjusted by adjustment screws that cooperate with a component provided in the hinge arm that is constructed to provide a cushioning volume that is available. When the hinge is modified for other built-in situations, at least one additional "flip lever" is built in. In addition, the buffer is identical to the hinge arm, and the flip lever has a corresponding joint, and the corresponding joint can be used. Curved corner (Kr Pfung). This requires additional construction and increases the complexity of the hinge. A further disadvantage is the height of the hinge arm (in addition to the required adjustment mechanism, as well as the bulky buffer).

It is an object of the present invention to provide a furniture hinge having a cushioning function that is compact in construction 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.

In the hinge of the present invention, the damper is disposed between the intermediate member and the guide lever along the piston rod in one direction, so that the hinge is tightly constructed without affecting the functionality. As such, the bumper can be integrated into a housing of a hinge in a simple manner, wherein the piston of the bumper extends parallel to the longitudinal extent of the housing. And disposed between the carrying lever and the shaft of the guiding lever. The second hinge portion is pivotally connected by a parallel link formed by the carrying lever and the guiding lever, and the shaft of the carrying lever and the guiding lever are disposed at a certain distance, so that the piston rod of the buffer can be effectively closed It is built into this intermediate space so it does not make the hinge's housing construction larger. The piston rod can be constructed tightly and a tip is embedded in a closed position between the guiding lever and the shaft carrying the lever. In addition, it can be applied to existing hinge types to integrate the bumper.

According to a preferred embodiment of the present invention, an adjustment means is provided between the intermediate member and the first hinge portion, which are disposed adjacent to the buffer.

The first hinge portion is preferably designed in the form of a housing in which the bumper and the intermediate member are housed. In this way, the damper and other movable members are arranged in a protected manner, thus reducing the risk of injury.

A cantilever can be provided on the guiding lever, on which the piston rod of the damper is fixed. Thus the furniture hinge can be designed with fewer components and the piston rod can be pivotally attached to the cantilever. Furthermore, the damper can be pivotally held on the first hinge portion so that no lateral forces are applied to the piston rod and the surrounding damper housing. The shaft of the damper on the hinge portion can be provided on the extension of the piston rod so that in the damper, the force is transmitted only in the direction of the piston rod.

The damper preferably has a cylindrical housing on which the plugs are formed, projecting from the sides, the plugs being embedded in the openings in the first hinge portion. Thus the damper can be mounted on the hinge portion in a simple manner, wherein the plug is inserted into the corresponding opening. In this case, the plugs can also form the pivot of the housing of the damper at the same time.

According to another design of the invention, the damper has a lower resistance in the opening direction than in the closing direction. This is because if the opening action is easy to achieve, and when it is closed, the buffering action is caused in the front of the closing position, which is desirable in the case of the furniture door, so it is sufficient if the buffer acts mainly in one direction. Here, the furniture hinge can be prestressed in the closing direction by means of a spring, so that when closed, the damper acts as a spring, so that the spring holds the furniture door in the closed position.

The invention will be described in detail below with reference to a number of embodiments.

A furniture hinge (1) comprises a mounting plate (2) which, for example, can be fixed to a specific one by means of screws. An intermediate piece (3) is provided on the mounting plate (2) and is arranged in a first hinge portion (16) designed in the form of a housing. The first hinge portion (16) is pivotally connected to a second hinge portion (4), and the second hinge portion (4) is formed with a can portion (5). For example, it can be placed on a furniture door. In the associated housing, the second hinge portion (4) has a plate surrounding the can portion (5), and the plate defines an opening (6) for screwing.

The second hinge portion (4) is pivotally connected to the first hinge portion (16) via a carrying lever (7) and a guiding lever (9), wherein the carrying lever (7) is set to be rotatable via a shaft (17) On the second hinge portion (16), and the guiding lever (9) is rotatably provided on the first hinge portion (4) via a shaft (18). Further, a rotating shaft (8) is formed on the first hinge portion (16) to pivotally connect the carrying lever (7), and a rotating shaft (10) is formed to pivotally connect the guiding lever (9). Thus, the first hinge portion (16) is pivotable relative to the second hinge portion (4), wherein the carrying lever (7) and the guiding lever (9) preset the pivoting movement in a manner of a parallel link.

A cantilever (11) is formed on the guiding lever (9), and a damper (12) is coupled thereto. The damper (12) has a linearly movable piston rod (20) that is coupled to the boom (11) in a rotatable manner. A plate (23) is fixed to the piston rod (20), and the piston body (21) rests on the plate, wherein the plate (23) and the piston body (21) are in a cylindrical housing portion of the damper (12). Movement within the segment. A sealing element (22) is provided around the piston body (2). Here, the damper (12) is designed in the form of a tension damper, in other words, if it is pulled over the piston rod (20) via the cantilever (11), it causes a damping force, while in the opposite direction there is only a small damping force. Thus, when a furniture door is opened, only a small cushioning force is perceived, and when the furniture door is closed, there is a large cushioning force. For example, the buffer (12) can be designed in the form of a hydraulic buffer or a pneumatic buffer.

The damper (12) is supported for rotation about a shaft (24) which is disposed in the extension of the piston rod (20). Here, a longitudinal axis of the piston rod (20) intersects the shaft (24) so that force is only absorbed in the reverse direction of the piston (20) via the damper (12) and does not absorb lateral forces. The shaft (24) is extended outward by a bolt (13) which is fixed to the casing (12). Here, the bolt (13) is embedded in the opening in the first hinge portion (16), so that the damper (12) can be accommodated in the first hinge portion (16) in a pivotable manner.

The damper (12) includes a cylindrical inner space (25) in which the piston body (21) is movable. When the piston body (21) moves with the piston rod (20), it must be volume balanced because the volume of the piston rod (20) increases or decreases in the damper. To this end, an elongate continuation (26) is formed adjacent to the shaft (24), the continuation (26) having a smaller cross section than the cylindrical inner space (25) and preferably 50% smaller and parallel to the piston The rod (20) extends. Here, the continuation (26) contains an elastic element, such as a Moosgummi, which balances the volume. Due to the tubular design of the continuation (26), the construction space within the hinge housing can be utilized. If a resilient material is not used, a mechanical balancing element, such as a balancing piston, can also be accommodated in the continuation (26).

In addition, an adjustment mechanism is further disposed on the first hinge portion (16), wherein a screw (14) is provided for placement adjustment, and a screw (15) is used for depth adjustment, or at the first hinge portion (16) Set up another adjustment mechanism.

In Figure 2, the furniture hinge is shown in the open position. The can (5) of the second hinge portion (4) is disposed substantially parallel to a longitudinal extension of the piston rod (20) and the first hinge portion (16). To close, the second hinge portion (4) is pivoted such that, next to the damper (12), the piston rod (20) is moved to the left until the end position shown in Figure 3 is reached. In this closed position, a tip of the piston rod (20) is situated approximately between the shaft (8) carrying the lever (7) and the shaft (10) of the guiding lever (9). An extension of the piston rod (20) extends at least between the two shafts (8) and (10). In addition, a spring (19) is provided around the rotating shaft (8), and the spring (19) pushes the furniture hinge to the closed position, wherein the spring (19) acts only at the closing end of the movement.

A second embodiment of a furniture hinge (1') of the present invention is shown in Figs. 4-6, which is provided as a furniture hinge (1), wherein the same components are designated by the same reference numerals. In this embodiment, the hinge portion (16') is designed in a larger angled form, and the bumper (12) is mounted farther from the mounting plate (2). This can result in another opening movement in which the second hinge portion (4) is pivotally connected to the first hinge portion (16) via a carrying lever (7) and a guiding lever (9). The damper (12) is held on the first hinge portion (16') by pivoting about a rotating shaft (24), and includes a cylindrical inner space (25') and includes two segment shapes. The chamber (26') is adjacent to the running shaft (24) for volumetric balancing, and the two chambers are each filled with an elastic material. In this embodiment, an extension of the piston rod (20) also extends between the two shafts (8) and (10), as shown in Figures 5 and 6.

7 to 9 show a third embodiment of the furniture hinge (1') of the present invention, wherein the first hinge portion (16") is pivotally connected to a hinge portion (4), wherein there is a parallel link. It is formed by the carrying lever (7) and the guiding lever (9). The first hinge portion (16") has a receiving portion for receiving the buffer (12), and the mounting portion protrudes above the mounting plate (2), and The above embodiment has a thicker corner and the cymbal can perform another pivotal movement. However, the function of carrying the lever (7) with the guiding lever (9) and the damper (12) is as in the previous embodiment, wherein the damper (12) is arranged such that it pivots about the pivotable axis (24). The manner is fixed on the first hinge portion (16'), and the piston rod (20) is disposed such that a longitudinal axis of the piston rod (20) is embedded in the carrying lever (7) of the first hinge portion (16') and guiding Between the shafts (8) and (10) of the lever (9).

Figures 10 to 12 show a fourth embodiment of a furniture hinge (1''', in which the same components are designated by the same reference numerals. In this embodiment, the first hinge portion (16''') is still designed to be a thicker curved corner and has a receptacle that is slanted relative to the mounting plate (2) to accommodate the bumper (12). Another second hinge portion (4) having a can (5) is fixed to the first hinge portion (16''') via a carrying lever (7) and a guiding lever (9), wherein The parallel link is preset to be protected in a receiving portion of the second hinge portion (4) and the first hinge portion (16'''), wherein a piston rod (20) has a longitudinal axis which is carried on the lever ( 7) Extending between the shafts (8) and (10) of the guiding lever (9). The damper (12) is also provided on the first hinge portion (16''') so as to be rotatable about an axis (24).

Thus the same damper (12) can be used for different furniture hinges (1) (1") (1"". Other components can also be used in different configurations in the same configuration.

Another advantage of the hinge design of the present invention is that if it is adapted to specific furniture requirements, for example with a curved angle without additional slope adjustment (Kr Pfung), and changing the hinge configuration, the geometric properties are in the following areas: hinge arm / middle piece / placement and depth adjustment and mounting plate, and the following areas: hinge can / carry - and guide lever and buffer -- The system remains unchanged.
