Description

Hinge especially for furniture parts:

The invention relates to a hinge, in particular for furniture parts, with a body-side stop part and a door-side stop part, which are pivotally connected to one another via at least one hinge axis, a damper being mounted on one of the stop parts. Furthermore, the invention relates to a hinge, in particular for furniture parts, with two stop parts which are pivotally connected to one another via at least one hinge axis and a damper.

In modern furniture construction, dampers are used to prevent furniture parts that move too quickly or with too much force in the respective end position from causing strong shocks to the furniture. In particular, such dampers are used to dampen the closing movement of a door or a drawer in the rearmost area. Both linear dampers, which can be designed as pneumatic or hydraulic dampers, and liquid dampers designed as rotary dampers are used as dampers. If, according to the known prior art, a door is to be damped, the damper is generally mounted on a side wall of a furniture or a furniture floor.

Furthermore, it is known to integrate the dampers as well as locking devices in the hinges.

The object of the invention is to improve a hinge of the type mentioned at the outset in such a way that an improved force dissipation occurs in the damping and therefore joint axes of the hinge are subject to less wear.

According to a first aspect of the invention, the object according to the invention is achieved in that the damper is supported twice on one and the same stop part via a three-point support.

It is advantageously provided in this aspect that the damper is acted upon by one of the stop parts and is supported on the same stop part via a connecting part separate from the stop part.

Another embodiment of the invention provides that one of the stop parts is designed as a hinge arm and the other stop part as a hinge cup and that

Damper is slidably mounted on the hinge arm, being from the hinge cup is applied. The hinge can be designed in a conventional manner as a four-bar hinge with two articulated levers and four hinge axes.

A further exemplary embodiment of the invention provides that a bearing block is provided for the connecting part in the hinge cup, the bearing block being formed by two disks which are located on both sides of the connecting part and in which a retaining pin for the connecting part is mounted.

According to a further aspect of the invention, however, the above-mentioned object can also be achieved

10. be solved by the damper having at least two mutually movable damper parts, wherein the first damper part can be pressurized by a first of the stop parts or a first stop that can be connected to it and the second damper part can be supported on a connecting part, the connecting part on the first Stop part or the first stop is rotatably and pivotably arranged and the

15 second damper part and / or the connecting part can be (are) displaced along a guide relative to the second stop part or a second stop that can be connected to it. It is provided here, for example, that the first stop part acts both on the first damper part and also serves as a suspension for the second damper part. The second stop part is completely relieved in the direction of the guide. It can

20, however, according to a preferred variant of this aspect, pressure is applied to the second stop part, preferably via pressure pieces correspondingly arranged on the connecting part or on the second damper part, essentially perpendicular to the guide. In this way it can be achieved that the forces of the damper acting on the second stop part are essentially normal, ie perpendicular to the furniture part

.5 to which the second stop part is fastened, whereby a relief of the suspension of the second stop part is achieved. It is preferably provided that the first damper part is pressurized directly by the first stop part and the guide is arranged directly on the second stop part. However, additional stops which can be connected to the respective stop parts of the hinge can also be used for this purpose

10 can be used. These additional stops can be, for example, the furniture parts to which the hinge is attached.

The connecting part is preferably a separate component of the hinge and thus in particular neither a stop part nor an articulated lever. 5 Exemplary embodiments of the invention are described below with reference to the figures of the accompanying drawings. Show it:

The hinge according to the invention of the first exemplary embodiment according to FIGS. 1 to 9c has, in a conventional manner, a hinge cup 1 which forms a first stop part and a hinge arm 2 which forms a second stop part. The hinge cup 1 and the hinge arm 2 are connected to one another via an outer articulated lever 3 and an inner articulated lever 4, which are supported on articulated axes 5 and 6. The hinge arm 2 is U-shaped in cross section with a central web 2 'and two side webs 2 ".

In the exemplary embodiment shown, the hinge arm 2 is mounted on an intermediate piece 8 by means of a joint adjustment screw 7. Between the hinge arm 2 and the intermediate piece 8, a shim 9 or screw is provided for the depth adjustment of the hinge arm 3. Such a hinge arm anchor is described in the applicant's Austrian utility model AT 01214 U.

While the hinge cup 1 can be inserted into a bore in a furniture door 19, the hinge arm 2 is hung together with the intermediate piece on a base plate 10, which is attached to a side wall 30 of the furniture, preferably screwed to it.

The hinge is equipped with a damper 13, which is designed as a fluid damper and in the exemplary embodiment as a linear damper. However, a rotary damper could also be used in all of the exemplary embodiments. The damper 13 has a cylinder with fastening projections 12. The damper 13 is placed on the central web 2 'of the hinge arm 2, the fastening projections 12 engaging around the edges 14 of a slot 15 in the central web 2 "of the hinge arm 2. The damper 13 is thus mounted on the hinge arm 2 so as to be displaceable in the longitudinal direction.

A piston 16 and a piston rod 17 are located in the cylinder of the damper 13. A cover cap 18 is mounted on the piston rod 17 and the hinge cup 1 presses on it when the door 19 is closed. When the door 19 is closed, the cover cap 18 with the piston rod 17 and the piston 16 are therefore moved in the cylinder of the damper 13. In the cylinder of the damper 13 there is also a return spring which, when the door 19 is opened, presses the piston 16 with the piston rod 17 and the cover cap 18 into the ready position. At the rear end of the cylinder of the damper 13, a connecting part 20 engages, which projects through the hinge arm 2 and is anchored with its front end 21 in the hinge cup 1. The rear end 22 of the connecting part 20 projects into a recess 23 in the cylinder of the damper 13. In the hinge cup 1 there is a bearing block 24 which consists of two 5 disks 25 which are arranged on both sides of the connecting part 20. The bearing block is supported on the one hand on the hinge axis 6, which connects the inner articulated lever 4 with the hinge cup 1, and on the other hand on an additional fastening pin 26. If the door 19 is closed and the hinge cup 1 strikes the cover cap 18 of the damper 13, the force is dissipated into the hinge cup 1 via the connecting part 20. The damper 13 is supported in a direction perpendicular to the furniture side wall 30 on the hinge arm 2, but the hinge axes 5 of the hinge in the hinge arm 2 and the hinge lever 3, 4 remain almost unloaded. 5 The damper 13 is thus supported during the closing process by means of a three-point support A, B, C (see FIG. 10 a) twice on the hinge cup 1 and once on the hinge arm 2, the direction of support being oriented perpendicular to the side wall 30 of the furniture.

20 Of course, the damper 13 could also be arranged rotated by 180 ° on the hinge arm 2 and a rotary damper could equally well be used, the piston rod 17 having to be replaced by a tappet, for example via a toothed rack profile and a pinion on the rotor of the rotary damper acts.

25 As already mentioned, the damper 13 is a fluid damper. It can be designed as a pneumatic as well as a hydraulic damper.

As in FIGS. 9a to 9c, a closing spring 28, which is supported in a conventional manner on the control cam $ 0 of a control part 29 fastened to the inner articulated lever 4, can be mounted on the articulated axis 5 of the hinge arm 2 for the outer articulated lever 3.

In the third exemplary embodiment according to FIGS. 13 to 16, the three-point support is again shown explicitly in FIG. 16. The damper 13 is supported here on the one hand via its piston 16 at point A on hinge cup 1 and on the other hand via hinge axis i5 37 and the connecting part 20 'at point B also on hinge cup 1. The third support point C is formed by the pressure piece 36, which is on the back 38 of the hinge arm 2 is applied. In all three exemplary embodiments, the third support point C is a sliding one that is not fixed to the hinge arm. In this regard, it should also be pointed out that the term support point is not to be understood in the sense of a mathematical point with an infinitesimally small area, but can also have a certain area and thus spatial extension in accordance with general usage. The exact mode of operation of the third exemplary embodiment according to FIGS. 13 to 16 is explained in detail below.

According to the second aspect of the present invention, a connecting part 20 or 20 'is provided in all of the exemplary embodiments, on which the second damper part - here the cylinder 31 - is mounted. The front end 21 or 21 'of the connecting parts 20, 20' is in each case pivotably or pivotably articulated on the first stop part - here the hinge cup 1. In the first two exemplary embodiments, this is done indirectly via the bearing block 24, while the rotatable or pivotable articulation in the third exemplary embodiment takes place directly on the hinge cup 1 via the axis 37 shown in FIG. 16. The first damper part - here the piston 16 or its cover cap 18 - is also supported on the first stop part, ie here the hinge cup 1, or is pressurized by it.

The damper 13, which is connected to the first stop part in this way at two points, is displaceably mounted via the connecting part 20 or 20 'relative to the second stop part - here the hinge arm 2. In all exemplary embodiments, the displacement takes place along a guide. In the preferred exemplary embodiments, this only allows a linear, preferably linear, movement, that is to say a back and forth movement, although this does not necessarily have to be straight, that is to say linear, but curved lines are also conceivable. In the exemplary embodiments according to FIGS. 1 to 12, this guide is formed by the slot 15. In the third exemplary embodiment according to FIGS. 13 to 16, the guide is designed as a guide groove 34 into which the guide pins 35 arranged fixed on the connecting part 20 'engage. The guide groove has limits which run at an approximately constant distance from one another.

In all three embodiments, the connecting part 20, 20 'and / or the second

Damper part - here the cylinder 31 - designed so that they only apply pressure to the second stop part, ie in this case the hinge arm 2, essentially perpendicular to the guide. This has the advantage that with this pressurization the hinge arm 2 or the base plate 10 are only applied normally, that is perpendicular to the furniture part 33. A load on the fastening screws 32 in a direction perpendicular to this is thereby avoided. There are therefore no shear forces between furniture part 30 and hinge arm 2 or base plate 10. In the first two 5 exemplary embodiments, this pressure is applied via the fastening projections 12 to the edges 14 of the guide slot 15. In the third exemplary embodiment, at least one, preferably two, pressure pieces 36 are provided for the pressure transmission from the connecting part 20 'to the back 38 of the hinge arm 2. These slide along the back 38 when, during the opening and closing movement of the furniture door 19, the connecting part 20 ′ slides in the guide groove 34 along the second stop part, that is to say here the hinge arm 2.

In the first exemplary embodiments, the connecting part 20 is arranged in regions inside the second stop part of the hinge arm 2. The third embodiment

15 according to FIGS. 13 to 16 differs from this by the design of the connecting part 20 'in the form of a U-shaped profile which surrounds the second stop part, that is to say the hinge arm 2. In all exemplary embodiments, the second damper part and the connecting part 20 or 20 ′ are elongated at least in some areas and are arranged essentially parallel to one another in this area.

In all three exemplary embodiments, the first damper part is pressurized directly by the first stop part and the guide is arranged on the second stop part. This does not have to be the case. Thus, a first stop can be connectable to the first stop part, the first damper part being pressurized by this first stop

.5 is applied. A simple variant for this would be, for example, that the piston 16 is not acted upon by the hinge cup 1 but directly by the furniture door 19. The same applies to leadership. This also does not necessarily have to be arranged on the second stop part, ie here the hinge arm 2. It can also be designed on a second stop that can be connected to the second stop part. This can in turn lead to

SO example, the furniture body 30 or an additional, for example screwed component. In any case, it is favorable if the stop parts can be fixedly connected to the additional stops. In all versions, however, the connecting part with the damper is connected to the hinge or integrated into it.

i5 As shown in the figures, the invention can be combined with numerous measures known per se. For example, the hinge can, as in Fig. 16, too see, be designed as a clip hinge, in which the hinge arm 2 can be clipped onto the base plate 10. A joint adjustment screw 7 known per se and / or a device 9 for depth adjustment can also be provided. The damper 13 can be designed both as a linear damper and as a rotary damper. The dampers shown in the exemplary embodiments are merely schematic examples. In addition, it does not necessarily have to be provided that the first stop part is the hinge cup 1 and the second stop part is the hinge arm 2. An inverted arrangement is also conceivable with adaptations according to the invention.
