Abstract

A furniture hinge has a door stop part, which includes an insertion cup and is attached on a furniture door, at least one pivoting arm that is connected to a furniture body being supported on the door stop part. A damping device including at least one damping cylinder engages in the door stop part. Each damping cylinder is disposed at least partially in a bore of the furniture door. The cylinder axis of the damping cylinder extends substantially perpendicularly to the door plane. The damping cylinder is moved during the pivoting thereof into the locking position of the furniture door by the pivoting arm.

Description

The invention relates to a furniture hinge with a Einstecktopf having, attached to a furniture door door hinge part on which a connected to a furniture carcass arm is mounted, and with an attacking on the door stop part, at least one damping cylinder having damping device.

The closing force exerted on the furniture door to be closed by a furniture hinge causes the furniture door to hit the furniture body abruptly, especially during rapid closing movement. In order to reduce this impact and the noise generated thereby, it is known to attach to the furniture body or furniture door buffers, but cause only a small reduction in the impact of the furniture door because of their necessarily small thickness.

It is therefore known to attach a damping device to the furniture hinge, which hits the furniture door at the end of its closing movement. The damping device has a damping cylinder, on the piston rod hits the furniture door or a fitting part attached thereto, so that the furniture door is slowed down until fully closed. Since the damping effect of the damping cylinder is speed-dependent, the damping device exerts in the closed state of the furniture door no force on the furniture door, through which the closed furniture door could be brought out of its closed position.

In a known furniture hinge of the type mentioned ( EP 1 538 293 B1 ), the damping device is mounted on the body-side stop member and engages the door hinge part. In another known, combined with a damping device furniture hinge ( US 2004/0205935 A1 ) of the type mentioned above, the piston rod of the damping cylinder protrudes the damping device attached to the body-side stop member in the direction of the furniture door. When closing the furniture door whose door stop part meets the free end of the piston rod, so that the movement of the furniture door is braked damping.

Another example of a known furniture hinge is in the document DE 9210092 U1 disclosed.

The known embodiments of combined with a damping device furniture hinges have in common that the space required for the damping device additional space is considerable. The free carcass interior is restricted by the damping device projecting there.

The object of the invention is therefore to design a furniture hinge with a damping device of the type mentioned so that no or at most only a very small additional visible space required for the damping device.

This object is achieved by the features of claim 1.

Since the damping cylinders are arranged predominantly in holes in the furniture door, they do not require any additional space and, in particular, do not protrude into the interior of the carcass. At the body side stop member no additional components are required to pressurize the damping device. For this purpose, the already existing, mounted on Einstecktopf pivot arm is used.

In the execution of the furniture hinge as a multi-joint furniture hinge of the swivel arm is formed by one of the two hinge arms.

In the embodiment of the furniture hinge as a single-folding furniture hinge the support arm mounted on the insertion pot, which is connected to the furniture carcass, acts on the damping device acting on the swivel arm, which performs a pivoting movement relative to the closing movement of the furniture door.

The one or the two damping cylinders of the damping device may be arranged at least partially within a pot bore receiving the plug-in pot in the furniture door. This is usually in the pot bore enough space available, so that on a additional bore for receiving the damping cylinder can be dispensed with.

Instead, it is also possible to arrange the damping cylinder in each case at least partially in a lying next to the pot bore hole of the furniture door.

The damping cylinders can also be arranged at least partially in a dowel hole, which receives a fixing dowel of the door stop member. Even if this makes it necessary to increase the diameter of the dowel hole compared with the usual dowel holes, this does not increase the drilling effort.

Further advantageous embodiments of the inventive concept are the subject of further subclaims.

That in the Fig. 1-3 Furniture hinge shown in successive positions during the closing movement is attached to a body-side stop member 1 on an inner wall 2 of a furniture body 3. About two hinge arms 4, 5, which are mounted on the body-side stop member 1 in joints 6, 7, articulated via hinges 8, 9 attached to a furniture door 10 door hinge part 11. The door stop member 11 has a Einstecktopf 12 or impact pot, which is received in a pot bore 13 of the furniture door 10. The one hinge arm 4 in this case forms a pivot arm, via which the door stop part 11 is mounted on the body-side stop member 1.

A combined with the furniture hinge damping device 14 has two damping cylinder 15, which are rigidly interconnected by a bridge 16. Each damping cylinder 15 has a cylinder housing 17 in which a (not shown) damping piston is taken longitudinally movable. A pressure medium (liquid or gas) flowing through the damping bores during the piston movement causes a damping of the piston movement. The piston is connected to a piston rod 18, which protrudes from the cylinder housing 17 and is supported on the bottom 19 of the Einstecktopfes 12. The damping cylinder 17 is movably guided in the insertion pot 12.

The swivel arm 4 (hinge link) comes with its pivoting movement during the closing process ( Fig. 1-3 ) for abutment on a bridge middle part 20 of the bridge 16 (FIG. 2) arranged between the two damping cylinders 15 (FIG. Fig. 7 ). As the closing movement progresses into the closed position of the furniture door 10 (FIG. Fig. 3 ) takes the pivot lever 4, the two damping cylinder 15, wherein the closing force counteracting damping force slows the closing movement of the furniture door 10 until it comes gently and without impact on the body 3 to the plant ( Fig. 3 ).

How to get out of the Fig. 1-4 detects, the two damping cylinder 15 are arranged to a substantial extent in the pot bore 13. The cylinder axes of the damping cylinder 15 are substantially perpendicular to the door plane, so that the damping force of the movement of the furniture door 10 acts directly opposite.

From the in Fig. 4 shown hole pattern in the pot bore 13 of the furniture door 10 it can be seen that the damping cylinder 15 receiving holes 20 overlap with the pot bore 13. On both sides are Dowel holes 21 are arranged, each receiving a fixing dowel of the door stop member 11.

Fig. 8 shows the door stop member 11 prior to insertion into the pot bore 13th

A modified embodiment of a furniture hinge has a door hinge part, whose individual parts in the Fig. 9-13 are shown. This embodiment differs from the previously described embodiment substantially only in that no separate holes for receiving the damping cylinder 15 are provided. The damping cylinder 15 are in this case received in the interior of the Einstecktopfes 12 and thus the associated pot bore 13. The door stopper 11, which is in Fig. 13 partially in section and partially shown in a view, has laterally next to the Einstecktopf 12 fixing dowels 22, which serve for attachment in the dowel holes 21.

In the Fig. 14-17 Parts of the door stop part of a further embodiment are shown, which differs from the previously described embodiments essentially only in that the two connected by the bridge 16 damping cylinder 15 are each at least partially disposed in a bore 23 of the fixing dowel 22 in the dowel hole 21st is included. The two damping cylinders 15 are thus arranged at least partially in the dowel hole 21. In addition, a screw hole 24 extends into the fixing dowel 22, which has a screw for attaching a (not shown) receives sheet metal cover of the stop member.

Since in this case the two bores receiving the damping cylinders 15 are separated from the borehole 13, the bridge 16 is connected to the two damping cylinders 15 arranged laterally only above the upper ribs 16 'in order to allow an unobstructed submerged movement of the damping cylinders 15 into the bores 23.

That in the Fig. 19-23 illustrated embodiment differs from the embodiment according to the Fig. 14-18 essentially in that the two dowel bores 21 affect the pot bore 13. The required, slightly wider breakthrough is generated by pressing in the Einstecktopfes by material displacement.

That in the Fig. 24-28 illustrated embodiment differs from the embodiment of the Fig. 1-3 only in that the swivel arm 4 of the multi-joint furniture hinge via a coaxial with the swivel arm 4 on the insertion pot 12 mounted pivoting flap 25 (FIGS. Fig. 27, 28 ) acts on the bridge middle part 20 of the bridge 16 between the two damping cylinders 15.

In the execution of the Fig. 29-31 has a modified embodiment of the pivoting flap 25 'has two laterally projecting tabs 26 which are supported on the piston rods 18 of the two damping cylinder 15. The cylinder housing 17 of the damping cylinder 15 are in this case in the holes 23 of the fixing dowels 22nd arranged. The two damping cylinders 15 are connected to each other only by the door hinge part 11.

Fig. 34 shows partly in section and partly in a view the assembled parts of the door hinge part 11 in an embodiment similar to the Fig. 17 , The cylinder housing 17 of the two damping cylinder 15 are rigidly interconnected by the bridge 16, on the bridge center portion 20 of the (not shown here) swivel arm 4 directly or via a pivoting flap 25 according to Fig. 27, 28 acts. The piston rods 18 of the two damping cylinders 15 are supported at the bottom of the bores 23 in the fastening dowels 22. A sheet metal or die-cast cover 27 is fastened by screws 28 to the plastic part of the door stop part 11. The fastening dowels 22 are made in one piece with the Einstecktopf 12 made of plastic; However, they can also be carried out individually.

Fig. 35 shows a plan view of the rigidly connected by the bridge damping cylinder 15, which in Fig. 36 are shown in a view.

Fig. 37 shows the hole pattern of the pot bore 13 and the two dowel holes 21 for receiving the door hinge part 11 according to Fig. 34 ,

While in the Fig. 1-37 Multi-joint furniture hinges are shown in FIGS. 38 and 39 each a Eingelenk-furniture hinge between the furniture door 10 and the furniture body 3 shown. Here, a support arm 29 is screwed to the body 3. In a hinge 30 is the door hinge part 11 'pivotally mounted on the support arm 29, which is received with its Einstecktopf 12' in the pot bore 13 of the furniture door 10.

One or two damping cylinders 15 are in this case arranged in the pot bore 13 with directed perpendicular to the door surface cylinder axis and during the closing operation by a protruding arm 29 on the arm 31 (FIGS. Fig. 38 ) or the support arm itself ( Fig. 39 ) acted upon at the end of the closing movement of the furniture door 10 in order to achieve a damping effect.

Fig. 40 shows that one of the bridges 16 ( Fig. 5-7 ) comparable bridge 16 'is mounted as a pivoting part on one side in a pivot bearing 32. The other end is supported on a single damping cylinder 15.

Fig. 41 shows larger holes 21 'for larger damping cylinder laterally adjacent to the pot bore 13. The attachment is made by screws 33 without pre-drilling in the support plate.

In all the embodiments shown, the damping cylinders 15 may also be removable in order to reduce the damping effect when using a plurality of furniture hinges.
