Description

Furniture hinge with rotary steamer

The present invention relates to a furniture hinge with at least two stop members for attachment to furniture parts, wherein one of the stop members is formed as a hinge arm, and with at least one pivotable during the hinge movement of the articulated lever and a rotary steamer for steaming a hinge movement

Furthermore, the invention relates to a piece of furniture with at least one furniture hinge of the type to be described

Rotary steamer for steaming hinge movements are often designed as a fluid steamer with at least two Dampfungsbauteilen - at least during Dampfungshub - are arranged rotatable relative to each other between the two Dampfungsbauteilen a space (preferably a shear gap) is provided with a Dampfungsfluid act on the during the Dampfungshubes shear forces Thus, a steam effect can be generated. Rotary steamers usually have a path-dependent damping function, ie the degree of damping depends on the length of rotation of the two steaming components relative to one another. Thus, a certain steam path must be provided in order to achieve the desired smooth evaporation Demands again and again on limits, which are given by the geometry of the furniture hinge So it is often difficult to integrate a rotary steamer in the furniture hinge so that on the one hand the D at a certain relative position of the abutment parts to each other and on the other hand, however, a sufficient Drehwinkeibereich a Dampfungsbauteils is covered relative to the other Dampfungsbauteil

Object of the present invention is therefore to propose a furniture hinge of the type mentioned, with good steaming results can be achieved even with large opening angles of the furniture hinge

This is according to the invention in an advantageous embodiment achieved in that by the pivotable hinge lever a slidably mounted on the hinge arm slider is driven and that the slider acts on a rotational transmission via a Ubertragungsmechanismus The invention can be implemented particularly advantageously in connection with wide-angle hinges which have at least seven axes of rotation. In general, with a wide-angle hinge, an opening angle greater than 90 ° is achieved. Frequently, such wide-angle hinges have a maximum opening angle of 170 ° to 180 °. Wide-angle hinges are often provided for extension of the hinge arm with spacers which are movably arranged between the actual stop parts (the hinge arm or the hinge cup) via the articulated lever These articulated lever pivoted during the hinge movement is now exploited to the effect by at least one of these articulated levers for loading the Slider is mounted on the hinge arm and during the Dämpfweges relative to this - preferably translational - is movable This linear movement of the slider is transmitted via a transmission mechanism (for example, a rack and pinion arrangement) on the rotary steamer, whereby an opening and / or or closing movement of Mόbelscharniers is damped. In this case, the transmission mechanism can have a transmission, by means of which a swept-back pivoting angle range of the articulated lever can be translated to a higher rotation angle range of the rotational damper. Thus, even a relatively small pivoting movement of the articulated lever is sufficient to trigger a correspondingly higher rotational movement of the rotary damper, so that a sufficient shear of the damping fluid between the two damping components of the rotary steamer is ensured.

In a possible embodiment of the invention can be provided that the slide is separated from the articulated lever and that the slider but only a predetermined relative position of the stop members to each other from the toggle lever is acted upon. In other words, no forced coupling of the

Rotary damper can be provided. The toggle lever is therefore movable over the majority of its pivotal movement independently of the slide and acts on the slide only from a predetermined relative position of the stop members to each other Die

Actuation of the slider on the toggle lever is made by pure contact, ie the toggle is only loosely during the damping stroke on the slider, in the opening movement, however, the hinge lever can lift off the slide immediately, so that the furniture hinge is independent of the rotary damper in the fully open position movable. In a possible embodiment of the invention can be provided that the rotary steamer is mounted on a second abutment part facing away from the end of the hinge arm In the prior art, it was previously common practice to arrange the rotary steamer on the hinge arm, but in close proximity to a joint axis connecting the two stop parts However, in the present invention, the rotary steamer can be arranged at the free end of the hinge arm, with a total of more free space available The rotary steamer can be arranged so that all components thereof (ie the rotary steamer in its entirety) during the Dampfungshubes relative to the hinge arm as also move relative to the second stop member (for example, the hinge cup) Thus, the beginning, the course and the end of the Dampfungsvorganges be further influenced

The furniture according to the invention is characterized by at least one furniture hinge of the type described

1 shows a cabinet-shaped furniture 1 with a furniture body 1 a and a furniture part 1 b which can be pivoted relative thereto. The furniture hinges 2 are mounted so as to be movable in limited movement between two closed furniture hinges 2. The furniture hinges 2 are preferably designed as wide-angle hinges, ie the movable one Furniture part 1 b can assume an opening angle of more than 90 ° relative to the front side of the furniture body 1a The furniture hinges 2 have as stop members each have a hinge arm 3 and a hinge cup 4, which is sunk in a bore of the movable furniture part 1 b

2 shows a perspective view of the furniture hinge 2, the hinge arm 3 with a known in the prior art mounting plate 5 is releasably latched The second stop member is executed in the illustrated embodiment as a hinge cup 4, which is provided for connection to the movable furniture part 1 b Intermediate piece 6 is forcibly guided via two pivotable articulated levers 7a, 7b relative to the hinge arm 3. At the intermediate piece 6 an intermediate lever 8a is articulated, which is articulated to the hinge cup 4 via another intermediate lever 8b Of particular importance is a movable slide 9, which is at the free rear End of the hinge arm 3 is mounted and which is linearly movable at least during the Dampfungshubes relative to the hinge arm 3. The pivotable hinge lever 7a is provided for loading the slider 9, which in the course of the closing movement of the furniture hinge 2 only from a predetermined relative position of the Sc By this triggered linear movement of the slider 9 is a on the slide 9 (or on the hinge arm 3) mounted rotary steamer 10 drivable for selectively switching on and off the Dampfungsfunktion the rotary steamer 10, a switching member 11 is provided which is adjustable transversely to a longitudinal axis of the hinge arm 3.

3a-3c show side views of the furniture hinge 2 in temporal sequences of the damping process in the direction of the closed position. In Fig. 3a, an open position of the furniture hinge 2 is shown. The furniture hinge 2 is formed as a wide-angle hinge with at least seven axes of rotation S1, S2, S3, S4, S5, S6 and S7, wherein the axis of rotation S6 is within the hinge cup 4. The articulated lever 7a, which on the one hand via the rotational axis S1 to the stationary hinge arm 3 and on the other hand with the movable intermediate piece 6 via the rotational axis S2 is pivotally connected, is provided for acting on the movable slide 9 In Fig 3a, the hinge lever 7a to the carriage 9 spaced whereby the rotary damper 10 mounted in or on the slide 9 or in or on the hinge arm 3 is initially not active

In Fig. 3b it can be seen that in the relative position of the hinge cup 4 shown to the hinge arm 3 of the articulated lever 7a auftπfft on the slide 9, whereby the damping process begins. In the further closing movement of the slider 9 is moved by the hinge lever 7a relative to the hinge arm 3 in a rear end position, as shown in Fig. 3c. Fig. 3c thus shows the furniture hinge 2 in the fully closed position. Due to the triggered linear movement of the slider 9, the rotational damper 10 not shown here can be driven, so that the movement of the articulated lever 7a (and thus the closing movement of the furniture hinge 2) can take place in a steamed manner. Starting from the complete closed position according to FIG. 3 c, the furniture hinge 2 can be opened again, wherein the pivotable articulated lever 7 a immediately lifts off from the slide 9 and the furniture hinge can be moved in the direction of the open position in a manner decoupled from the rotary steamer. To return the slider 9 to a position provided for the next damping stroke, a return mechanism (e.g., a return spring) is provided by which the slider 9 can be moved back to a position as shown in Fig. 3a. Optionally, the slider 9 also (not shown) have lateral projections on which the articulated lever 7a can impinge.

Fig. 4a shows a perspective view of the furniture hinge 2 in one

Open position. Visible are the two stop parts in the form of the hinge arm 3 and the hinge cup 4. By the intermediate piece 6, it is possible, the two

Furniture parts 1a, 1 b not only to pivot relative to each other, but also at Pivoting to increase their distance from each other. For this purpose, the intermediate piece 6 is pivoted over the hinge arm 3 by the articulated levers 7a, 7b, starting from the closed position shown in FIG. 4b, and extends it into an open position, as shown in FIG. 4a. This ensures that the two stop parts 3, 4 in the two end positions are far different from each other. In Fig. 4a, the switching member 11 is also shown in a switching position in which the hinge movement takes place attenuated. In the course of the closing movement, the two lateral articulated levers 7a strike the slide 9 and displace it to the rear, whereby a damping effect is generated. In Fig. 4b, however, the switching element 1 1 is shown in a switching position in which the hinge movement runs undamped. Thus, it is therefore up to the user to provide by a corresponding actuation of the switching element 1 1 either a damping effect of the furniture hinge 2 or not.

5a-5e show different views of the linearly movable slide 9 and the switching member 11 for deactivating the damping function of the rotary damper 10. The slider 9 is also formed in the embodiment shown as a housing for the rotary damper 10. In Fig. 5a, the slider 9 is visible with the integrated therein rotary damper 10, wherein a shaft 10a is provided with a pinion 10b mounted thereon for driving the rotary damper 10. By the switching member 1 1 - which is not shown in Fig. 5a - the switch knob 10 along the shaft 10 a can be moved axially, whereby the damping effect can be deactivated. In Fig. 5b, the underside of the hinge arm 3 is shown in a perspective view, wherein the transmission mechanism T is shown. On the hinge arm 3, a stationary rack 10c is arranged, along which the pinion 10b can run when the slide 9 is acted upon by the articulated lever 7a. Recognizable is a return mechanism 13 in the form of a torsion spring, which is stretched during the damping stroke by the method of the carriage 9. After damping, the pinion 10b is moved by the stored energy of the torsion spring in the opposite direction of rotation, whereby the slider 9 is moved back into a position provided for the next damping stroke position. The return mechanism 13 with the torsion spring thus acts between slide 9 and the pinion 10b. In mechanical reversal, it is also possible to arrange the rotary damper 10 with the pinion 10b on the hinge arm 3 and the rack 10c on the movable slide 9. 5d shows a schematic view from below of FIG. 5d shows a plan view of the switching element 11 FIG. 5e shows a sectional view of the switching element 11 along the arrows according to FIG. 5d. FIG. 5e shows an oblique link 11a for raising or lowering the in. FIG Fig 5a shown switching knob 12 can be seen, wherein in a lowered position of the switch knob 12, the Dampfungsfunktion the rotary steamer 10 is deactivated

FIG. 6 shows the body-side part of the furniture hinge 2 in an exploded view. The furniture hinge 2 can be loosely locked via a plate holder 14 with a mounting plate 5 as shown in FIG. 2. The relative position of the hinge arm 3 to the plate holder 14 is via a depth adjustment device 15a or over A Hohenverstelleinnchtung 15b changeable adjustable Visible is the stationary on the hinge arm 3 arranged rack 10c, which is provided for combing with the pinion 10b of the rotary steamers 10 The jerk mechanism 13 in the form of the torsion spring is used to turn back the pinion 10b, whereby the slider 9 back into a On the shaft 10a, a rotatable Dampfungsbauteil 16 is mounted, which is rotatably arranged in mounting position relative to the slide 9. Between the Dampfungsbauteil 16 and the slide 9, a shear gap with a Dampfungsfluid is effective also includes the Ro tationsdampfer 10 an overrunning clutch 20 with a rotatable by the switching element 1 1 cage 20a, wherein in a first switching position of the switching element 1 1 a Dampfungsfunktion the furniture hinge 2 is provided and wherein in a second switching position of the switching element 1 1, the Dampfungsfunktion is disabled controlled by this the switching member 11, which lowers the switching knob 12 via the slide 11 shown in FIG. 5e, whereby the cage 20a is rotated and thereby the damping member 16 is decoupled from the rotational movement of the shaft 10a. The intermediate piece 6 is connected to the hinge arm 3 via the hinge lever 7a The articulated lever 7a serves on the one hand to act on the carriage 9, on the other hand to connect the intermediate piece 10 to the hinge arm 3

FIGS. 7a and 7b show a very simple construction for deactivating the damping function of the rotary steam generator 10. An adjustment of the switching element 11 (FIG. 6) permits axial displacement of the shaft 10a with the pinion 10b arranged thereon so that the pinion 10b moves out of the rack 10c The disengaged position of the toothed wheel 10b is shown in FIG. 7a, wherein the hinge movement can proceed without damping. In FIG. 10b, on the other hand, the switching element is shown 11 is set so that the pinion 10b is in engagement with the rack 10c, whereby a hinge movement is damped.

FIGS. 8a and 8b show a further possibility for deactivating the damping function of the rotary damper 10. The illustrations shown show perspective vertical sections of the slide 9 with the rotational damper 10 arranged therein. The shaft 10a drivable by the pinion 10b as well as the rotatable within the slide 9 are arranged Damping member 16, wherein between the damping member 16 and the slider 9, an annular shear gap 18 for receiving a damping fluid remains. 8a in a switching position in which the damping function of the rotary damper 10 is deactivated by the switching member 11 is at least one clamp body 19 in the circumferential direction of the shaft 10a controllable, which selectively couples the damping member 16 with the movement of the shaft 10a , The clamping body 19 has been highlighted for reasons of better understanding of the cutting plane. In Fig. 8a, the Klemmkorper 19 thus no clamp connection between the shaft 10a and damping member 16 forth, whereby no relative movement of the damping member 16 takes place to the outer slide 9. The hinge movement thus runs undamped.

In contrast, in Fig. 8b, the switching element 11 has been moved to a further switching position, whereby now the clamping body 19 produces a clamping connection between the shaft 10a and the damping member 16. If now the shaft 10a is moved over the pinion 10b, the damping component 16 is also moved along with the shaft 10a due to the clamping connection. Thus, there is a relative movement between the damping member 16 and the outer slide 9, wherein this movement is decelerated by the arranged in the shear gap 18 damping fluid.

Fig. 9a-9d show different views switching button 12, which is adjustable in height by an adjustment of the switching member 11 via the gate 11 a (Fig. 5e). 9a shows the central shaft 10a with the damping component 16 which can be coupled thereto, wherein an annular shear gap 18 for absorbing the damping fluid remains between the damping component 16 and the slider 9. Fig. 9a shows the raised position of the switch button 12, so that the damping function is disabled. 9b shows an enlarged detail view of the area circled in FIG. 9a. In Fig. 9b, the switch knob 12 has arranged inclined surfaces 12a, which can cooperate with corresponding inclined surfaces of a shaft 10a surrounding the cage 20a The switch knob 12 can only be moved axially relative to the shaft 10a due to the non-circular cross section. In a purely axial movement of the switch knob 12 relative to the shaft 10a, therefore, the cage 20a in Umfangsπchtung the shaft 10a rotated This situation is in Fig. 9c and in particular in By a downward movement of the switch knob 12 - caused by an adjustment of the switching element 11 - the cage 20a is rotatable whereby the (not apparent here) Klemmkorper 19 couple the Dampfungsbauteil 16 with the shaft 10a, so so the Dampfungsbauteil 16 with However, the rotation of the Dampfungsbauteiles 16 is braked by arranged in the shear gap 18 Dampfungsfluid, so that thereby the hinge movement is braked to act on the cage 20a and the Klemmkorper 19 in the freewheeling position, a spring 21 is provided

Fig. 10a shows the shaft 10a with the surrounding clamping bodies 19, which optionally couple the rotatable damping component 16 to the rotational movement of the shaft 10a or not recognizable is the cage 20a (Figs 9a to 9c), by an adjusting movement of the switching member 11 and over the Switching knob 12 in Umfangsπchtung the shaft 10a is adjustable in Fig. 10a and in the enlarged detail of FIG 10b is no Dampfungsfunktion, since the Klemmkorper 19 each come to lie in recesses of the shaft 10a, whereby a rotational movement of the shaft 10a not on the Dampfungsbauteil 16th In Fig. 10c, however, the cage 20a was adjusted by the switching member 11 in the circumferential direction of the shaft 10a, so that the Klemmkorper 19 are moved out of the wells of the shaft 10a and now come to Schragflachen the shaft 10a to the plant, which thus a jamming connection between the shaft 10a and the rotatable Dampfungsbauteil 16 can be produced If al so that the shaft 10a is rotated via the pinion 10b, so the Dampfungsbauteil 16 is moved due to the frictional coupling by the switchable Klemmkorper 19 By arranged in the shear gap 18 Dampfungsfluid this movement is, however, steamed
