Description

Furniture hinge (1)

A furniture hinge having a mounting plate and a hinge portion having a side portion fixed to the mounting plate, the hinge portion being pivotable relative to the side portion between an open position and a closed position, and The carrying lever and a guiding lever are pivoted in a parallel link manner, wherein a buffer is provided in the side portion, and a housing and a piston rod are provided to buffer the movement between the side portion and the hinge portion.

A furniture hinge is disclosed in the European patent EP 1 555 372, in which a hinge portion is supported on one side and can be pivoted via two levers.

It is an object of the present invention to provide a furniture hinge that is simple in construction and that only has a cushioning effect in a desired pivot range.

This object is achieved by a furniture hinge having the features of claim 1 of the patent application.

According to the invention, the motion buffering buffer for the side portion and the hinge portion is designed such that the buffer is effective within an angle range of less than 45° in front of the closed position of the hinge portion (4). .

In this way, the cushioning effect can be avoided even if the hinge portion or a furniture door fixed thereto is already in the open position. Otherwise this will hinder the operation. Since the use of the damper is mainly to prevent the furniture door from being closed, it is sufficient if the damper acts only in the range of the front angle of the closed position of the hinge portion.

According to a preferred embodiment of the invention, the damper acts only in the range between 20° and 40° before the closed position, so that there is still a partial cushioning path, but it does not interfere with the operation of the furniture door.

In a preferred design, a steering lever is provided which is rotatably supported on the side portion which is coupled to the bumper on one side and to a link in the other. Due to the steering lever support or rotatable manner, the steering lever has a predetermined rotational movement on the side facing the bumper and on the side of the link. In this case, the connecting rod is preferably rotatably mounted on the carrying lever or the guiding lever, thus creating a compact construction. Here, the link can be arranged on the side of the side between the carrying lever and the axis of rotation of the guiding lever.

According to a preferred design of the present invention, the connecting rod is pivotally connected to the carrying lever facing the hinge portion, adjacent to the shaft provided on the side of the carrying lever, so when the hinge portion moves in the wide open position, the connecting rod The shaft moves a little, and when the hinge is closed, the carrying lever pivots, so the link moves at the same time. Here the link is pivotally connected to the carrying lever, so that the axis of rotation is arranged closer to the side of the hinge than to the axis of the hinge, for example about three of the length of the distance between the axes of the carrying lever One of the points.

To avoid lateral forces on the piston rod, the bumper can be coupled to the steering lever via a curved guide member, which can then be moved axially relative to the housing for cushioning. Here, the curved guide can be designed to form a long hole in the steering lever for connection with the damper. A pin is inserted into the slot, the pin is coupled to the piston rod or housing, and a point is determined using a curved guide or slot design. The damper starts to function at this point when the hinge is closed. When the curve guide is designed accordingly, the starting point can also be adjusted, and the buffer acts at this point during the closing motion.

In order to make the installation simple, the bumper can be fixed to the mounting plate and/or the side. In order to avoid lateral forces on the damper between the piston rod and the damper, the damper can also be held on the steering lever on one side and pivotally held on the opposite side on the opposite side.

The invention will be described in detail below using two embodiments in conjunction with the drawings.

A furniture hinge (1) made of metal and/or plastic is shown in Figs. 1A to 1C, which has a mounting plate (2) which can be firmly attached to a specific one. A side portion (1) is fixed to the side portion (3) firmly or via an adjustment mechanism, and a pot-shaped hinge portion (4) is pivotally supported on the side portion (1). The hinge portion (4) can be connected to a furniture door or to another member.

In order to pivot the hinge portion (4), a carrying lever (5) facing the hinge portion (4) and an adjacently disposed guiding lever (6) are provided, wherein the carrying lever (5) is pivoted via a shaft (7) Attached to the hinge portion (4) and pivoted to the side portion (3) via a (8), the guiding lever (6) is pivotally connected to the hinge portion (4) via a shaft (9) and passes through a shaft ( 10) pivotally connected to the side portion (3), such that the hinge portion (4) is movable relative to the side portion (3) via a predetermined pivoting path, wherein the carrying lever (5) and the guiding lever (6) constitute a Parallel links.

In order to buffer the movement of the hinge portion (4) in a portion of the pivoting range, a buffer is provided which has a housing (11) and a piston rod (12) movable relative to the housing (11). The buffer is designed in the form of a linear buffer. And for example, it can be a buffer or a barometric buffer.

The damper is connected to the piston rod (12) by a steering lever (13) which is supported on the side portion (3) for pivoting about a shaft (14). Furthermore, a shaft (17) is provided on the steering lever (13) with a link (18) or a lever pivotally connected to the shaft (17). The link or rod is fixed to the carrying lever via a shaft (19) on the opposite side. Here, the shaft (19) is provided on a frame strip (20) carrying the rod (5) which is arranged outside the carrying lever (5) towards the hinge portion (4). The shaft (19) is disposed between the shaft (7) on the hinge portion (4) and the upper shaft (8) of the side portion (3) such that the distance between the shaft (19) and the shaft (8) is greater than the shaft (7) The distance from the shaft (19) is shorter. For example, the shaft (19) divides the line between the shaft (7) and the shaft (8) by a factor of three to two-thirds.

A furniture hinge (1) in an open position is shown in Figure 1A, wherein the hinge portion (4) is pivoted such that the furniture door is in a 90° position in an open position.

To make a closing motion, pivot the hinge portion (4) as shown in Fig. 1B. By pivoting the hinge portion (4), the carrying lever (5) and the guiding lever (6) are pivoted, wherein the shaft (19) is at the beginning of the closing movement due to the selection of the axes (7) to (10) Almost no luck. In Figure 1B, the hinge portion is approximately at an angle a = about 95 in front of the closed position. Until this closing position, the damper is inactive because the piston rod (12) has not yet moved relative to the housing (11).

If the hinge portion (4) is further driven at this time, the carrying lever (5) is rotated in the counterclockwise direction, so that the link (18) moves in the direction of the steering lever (13), which pivots about the shaft (14) turn. Therefore, the first movement of the steering lever causes a bolt on the shaft (15) to be guided in a long hole (16) in the steering lever (13) until the bolt reaches the end of the long hole (16). Then, when the hinge portion (4) moves further, the link (18) and the steering lever (13) move in such a manner that the return rod is pushed into the housing (11).

Figure 1C shows the closed position of the furniture hinge (1) with the piston rod (12) moved into the housing (11) and the hinge portion (4) can be pivoted to an open position by the closed position, wherein the buffer is only There is a role in the initial range or only a one-way buffer, so the open process is not buffered. Here, the hinge portion (4) is prestressed by a spring to move to the closed position.

In the embodiment shown in Figures 1A to 1C, a long hole (16) is formed in the steering lever (13) as a curved guide member, wherein the elongated hole (16) does not determine the starting point of the effective range of the damper piston The starting point of the movement of the rod (12) relative to the housing (11). Other curved guides are not provided with the long holes (16), wherein, for example, the travel path when the steering lever (13) is rotated can be adjusted, and the open point of the effective range of the bumper can also be adjusted.

Another embodiment of the furniture hinge (1') of the present invention is shown in Figures 2A to 2C, wherein the same members are denoted by the same reference numerals as the first embodiment, and the furniture hinge (1') is fixed to a piece of furniture. a mounting plate (2) on the body (2), one side portion (3') is provided on or fixed to the mounting plate, and pivotally supports a linear buffer on the side portion (3'). There is a housing (11') and a piston rod (12').

One side of the piston rod (12') is fixed to a steering lever (13') via a shaft (15'), and the rotating lever is held on the side portion (3'), which is rotatable via a shaft (14'), and the steering lever (13) ') is connected to the carrying lever (5) by means of a connecting rod (18), wherein the connecting portion of the hinge portion (4) with the carrying lever (5) and the guiding lever (6) is designed as in the previous embodiment.

If the hinge portion (4) is now pivoted from a large open position (Fig. 2A) to a partially open position (Fig. 2B) (which is about 45 degrees before the closed position), the link (18) is pivoted On the carrying rod (5), the steering lever (13) does not move or moves very little, which has no effect on the damper having the housing (11') and the piston rod (12'). Until the range of 20°~40° in front of the closed position, the connecting rod (18) moves through the carrying lever (5), causing the steering lever (13') to rotate and the piston rod (12') to enter the housing (11'). Going in, as such, in the range of rotational motion of the steering lever (12'), the housing (11') pivots slightly about the shaft (21) to avoid lateral forces.

The closed position is shown in Figure 2C with the piston rod (12') in the moved-in position in the housing (11').

In the illustrated embodiment, the piston rod (12) or (12') is connected to the steering lever (13). Of course, the housing (11) or (11') can also be connected to the steering lever (13). And fix the piston rod (12) or (12') on the side (3) or (3').
