Description

The Invention relates to a furniture hinge with a door hinge part, the one in a pot hole of a furniture door has received insertion pot, with a pivotable thereto mounted, with a furniture body connected support arm and with one acting between the door stop member and the support arm, a damping cylinder having damping device.

The from a furniture hinge to be closed Furniture door exerted closing force causes the furniture door in particular abruptly hits the furniture carcass when closing fast. To this impact and the noise generated by it it is known on the furniture body or on the Furniture door to attach buffers, but because of their necessarily only small thickness only a small reduction effect the impact effect of the furniture door.

It is therefore known, the furniture hinge a damping device to attach to the furniture door at the end of her Closing movement hits. The damping device has a damping cylinder on the piston rod the furniture door or an attached fitting part meets, leaving the furniture door to the full Closing is slowed down. Because the damping effect the damping cylinder speed-dependent is, the damping device exercises in the closed Condition of the furniture door no force on the furniture door out, through which the furniture door out of its closed Position could be brought.

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.

The known embodiments of with a damping device combined furniture hinges is common that the for the damping device required additional Space requirement is considerable. The free corpus interior is limited by the there protruding damping device. In addition, the known furniture hinges are not suitable, optionally with or without damping device to be executed, in particular a subsequent Retrofitting with a damping device not or only with great effort is possible.

task The invention is therefore a furniture hinge with a Damping device of the type mentioned so form that for the damping device only a very small additional space requirement exists.

These The object is achieved according to the invention that the - preferably the only - damping cylinder in a receiving bore axially parallel laterally next to the pot bore is arranged and that the support arm has a stop projection, the relative to a pivotal movement of the door hinge part to the support arm with the piston rod of the damping cylinder enters into operative connection.

For the accommodation of the damping cylinder can be one of provided in the usual hole pattern next to the pot bore Dowel holes are used by placing on the assembly a fixing dowel is omitted, so that the dowel hole for receiving the damping cylinder available stands.

The Operative connection between the stop projection on the support arm and the Piston rod of the damping cylinder can be used in mechanical simple manner and in particular carried out without significant space requirements become. It also comes with simple measures and little effort retrofitting the furniture hinge with a damping device allows

According to one particularly preferred embodiment of the invention provided for this purpose, that on the damping cylinder a pivoting flap is mounted pivotably with a pivot axis, the right angle to the cylinder axis of the damping cylinder and at a distance to this on the side facing away from the support arm, and that the pivoting flap has a stop surface, which engages with the stopper projection of the support arm.

Instead of this one-sided arrangement of a pivoting flap can be provided in a further embodiment of the inventive idea that the pivoting flap is pivotally mounted in a pivot axis which is perpendicular to the cylinder axis of the damping cylinder and at a distance to this transverse to the pivoting plane of the support arm, and that the pivoting flap a Stop surface which engages with the stopper projection on the back of the pivot arm engages. The pivoting flap is mounted here on both sides of the support arm. The pivotal movement of the support arm relative to the door hinge part is hereby particularly favorable Transfer manner to the pivoting flap. Again, the damping cylinder is preferably only in one of the two dowel holes of the furniture door; However, it is also possible in this embodiment that both dowel holes of the furniture door each accommodate a damping cylinder, wherein the pivoting flap is then supported on the piston rods of both damping cylinder.

The Swing flap not only forms a simple transmission element, to the movement of the stop projection on the piston rod of the Transfer damper cylinder; the swing flap at the same time forms a reduction lever, with a larger Movement stroke of the stop projection into a smaller movement stroke of Piston rod of the damping cylinder is implemented. Thereby is it possible to use a damping cylinder with relative to use a small stroke length, but still a sufficient large damping stroke for the relative movement between the door hinge part and the support arm available stands. This small stroke length of the damping cylinder leads to a relative small overall length of the damping cylinder, so that the available, limited depth of the plug hole sufficient to accommodate the damping cylinder.

In Advantageous embodiment of the inventive concept is provided that the insertion pot has a metallic inner pot, the is arranged in a plastic insert, which is a substantially cylindrical pot peripheral surface forms, and that in at least one between the inner pot and the pot peripheral surface arranged portion of the plastic insert at least one retaining screw is arranged.

Especially It is advantageous if the stop projection on the support arm adjustable is appropriate. The stop projection can, for example, on the Support arm can be guided longitudinally adjustable. Instead it is also possible that the stop projection of a Stop head formed by means of an eccentric journal is rotatably mounted on the support arm.

These adjustable execution of the stop projection allows it to adjust the damping effect of the furniture hinge. As a result, a tolerance compensation made after assembly and the damping effect on the respectively desired Measure are set. In particular, it can also an optimal adjustment of the damping effect in terms on the mass of each connected furniture door be made.

Further advantageous embodiments of the inventive concept are the subject further dependent claims.

That in the 1 - 5 Furniture hinge shown has a swivel arm or arm 1 on, which is attached to a (not shown) body-side stop member on an inner wall of a furniture body. The support arm 1 is on an impact pot or plug-in pot 2 hinged, which in a pot bore 3 a furniture door 4 is included and a door hinge part 2a forms. When carrying out the furniture hinge as a multi-joint hinge, the support arm 1 for example, two handlebars with the insertion pot 2 be connected. One of the joints 5 of the support arm 1 is shown in the drawing.

The plug-in pot 2 has a preferably made of sheet metal inner pot 6 on that in a plastic insert 7 is arranged. The plastic insert 7 forms a substantially cylindrical pot peripheral surface 8th whose diameter is greater than the pot bore in the uninstalled state 3 , Two between the inner pot 6 and the pot peripheral surface 8th arranged areas of the plastic insert 7 each take one parallel to the top axis of the Einstecktopfes 2 screwed in retaining screw 10 on ( 5 ).

The in the pot peripheral surface 8th lying outer wall of the plastic insert 7 has retaining projections 9 in the manner of a harpoon toothing. When hammering the Einstecktopfes 2 The harpoon toothing is against the inner wall of the pot bore 3 pressed and anchored thus the Einstecktopf 2 in the pot hole 3 ,

The plastic insert 7 is over one on the inside surface of the furniture door 4 lying flange section 11 one-sided with a dowel 12 connected in a dowel hole 13 is used in a conventional manner and a retaining screw 14 receives.

The metallic inner pot 6 of the plug-in pot 2 is on the inside of the furniture door 4 with flanges extending in opposite directions 15 and 16 Mistake. The one metallic flange 15 lies above the plastic flange 11 and take the retaining screw 14 on.

The other metallic flange 16 lies directly on the inner surface 4a the furniture door 4 indicates and above the usual hole pattern ( 7 ) existing second dowel hole 17 a hole 18 on.

In this second dowel hole 17 is a damping cylinder 19 arranged, whose cylinder axis is parallel to the axis of the Einstecktopfes 2 and the pot hole 3 extends.

The damping cylinder 19 indicates at its from the dowel hole 17 outstanding end a bulge 20 on, which is formed for example by an inserted in a circumferential groove snap ring. The raised edge 21 the bore 18 of the flange 16 reaches over the bulge 20 and thus secures the damping cylinder 19 in the dowel hole 17 ,

That from the dowel hole 17 outstanding ending 19a of the damping cylinder 19 is with a collar 21 connected, on which a pivoting flap 22 in a pivot axis 23 is stored. The pivot axis 23 runs at right angles to the cylinder axis 19b of the damping cylinder 19 and is at a distance to this cylinder axis 19b on the support arm 1 arranged away side. The collar 21 could also be in one piece on the damping cylinder 19 be educated.

A piston rod 24 of the damping cylinder 19 touches the swing flap 22 preferably approximated in the middle. At the pivot axis 23 opposite end has the pivoting flap 22 a stop surface 25 on that in the in 1 shown position at the beginning of the damping stroke with a stop projection 26 of the support arm 1 engages.

In the illustrated embodiment, there is the stop projection 26 from a tab that is made of a sidewall 1a of the support arm 1 punched out and angled.

If at the end of the closing movement of the furniture door 4 in the 1 shown position is reached, presses the stop projection 26 during the further closing movement of the furniture door 4 on the stop surface 25 the swing flap 22 thereby moving towards the damping cylinder 19 is pivoted. This is the piston rod 24 against the force of the damping device in the damping cylinder 19 pushed. The further pivoting of the furniture door 4 until closed ( 2 ) is due to this movement of the piston rod 24 attenuated.

The described and in the 1 - 5 shown furniture hinge can be performed from the outset with the described damping device. But it is also possible to first perform the furniture hinge without damping device and retrofit the damping device later. This is in 6 shown. In the second dowel hole 17 This is initially only a plastic plug 27 arranged with a cover plate 28 connected is. If that is in 6 - 9 shown furniture hinge to be equipped with a damping device, the plastic plug 27 through the single damping cylinder 19 replaced, on which the pivoting flap 22 is stored in the manner previously described. The furniture hinge can thus be used either with or without damping device. Moreover, it is even possible to retrofit the furniture hinge, which was initially designed without a damping cylinder, subsequently with a damping device.

Deviating from the in the 1 - 6 illustrated embodiment of the support arm 1 in which the stop projection 26 from one out of the side wall 1a of the support arm 1 punched tab, can the stop tab 26 ' also on the support arm 1' be set up. This is in the 10 - 15 shown.

The support arm 1' has for this purpose an additional mounting hole 29 on, extending through the two side walls of the support arm 1' extends. The stop tab 26 ' is on average C-shaped and is on the support arm 1' placed across and fastened there. For fastening the stop projection 26 ' serves one through two pin holes 30 . 31 the C-shaped stop projection 26 ' and through the holes 29 of the support arm 1' pinned pin 32 , 12 shows the stop projection 26 ' on average in the assembled state. 14 shows the stop projection 26 ' before putting on the support arm 1' ,

In 15 is shown that instead of the pen 32 a screw 33 can be provided through the hole 30 inserted and in the bore executed as a threaded hole 31 is screwed in.

16 shows a plan view of the support arm 1' with a patch on it, in cross-section C-shaped stop projection 26 ' on the support arm 1' adjustably mounted, is guided in particular longitudinally adjustable. One with a Kreuzschlitzausnehmung 34 for attaching a Phillips rotary eccentric provided 35 is by means of an eccentric pin 36 ( 18 ) in a hole 37 of the support arm 1' rotatably mounted and in a guide recess 38 the stop projection 26 ' taken transiently.

As already with the example after the 12 - 14 described is the stop tab 26 ' by means of a pin inserted 39 on the support arm 1' appropriate. The pencil 39 each extends through a slot 40 in both side walls 41 of the support arm 1' ( 17 ). The two slots 40 extend in the longitudinal direction of the support arm 1' and allow a limited longitudinal displacement of the stop projection 26 ' upon rotation of the eccentric element 35 ,

By allowing in this way longitudinal adjustment of the stop projection 26 ' along the arm 1' the door opening angle is changed at which the stopper projection 26 ' on the stop surface 25 the swing flap 22 meets. As a result, the point of the start of damping and thus the damping effect are changed.

Another possibility of forming an adjustable stop projection is in the 19 and 20 shown. Here is the stopper projection 26 ' from a stopper head 42 formed by means of an eccentric journal 43 on the support arm 1' is rotatably mounted. The rotatable stopper head 42 is here on the side of the support arm 1' arranged. The journal 43 extends through both side walls 41 of the support arm 1' , That the stop head 42 turned away end of the journal 43 is by a riveting made by wobble riveting 44 secured. The tumble 44 is here designed so that the with a Phillips approach 45 provided stop head 42 can only be twisted by overcoming a considerable frictional force, so that the stopper head 42 its set by the setting rotational position during operation, ie when hitting the stop surface 25 the swing flap 22 , not changed.

In the 21 - 23 is in representations according to the 1 . 3 and 4 a modified embodiment of a furniture hinge shown. The execution after the 21 - 23 differs from the execution according to the 1 . 3 and 4 only in that the rotatable stopper head 42 holding the stop lug 26 ' forms, on the back 46 of the support arm 1' is arranged. The stop surface 25 for the stopper head 42 This is by an extension 47 the swing flap 22 educated.

The stopper head 42 has an eccentric journal 43 ' up in a hole 48 in the back 46 is determined in the manner previously described by a wobble riveting so that it can be rotated only by overcoming a considerable frictional force to the on the stop surface 25 to adjust acting stop and thus make an adjustment of the damping effect.

That in the 24 - 27 illustrated embodiment of a furniture hinge differs from the embodiment of the 21 - 23 essentially by having a pivoting flap 49 in a pivot axis 50 is pivotally mounted, which is perpendicular to the cylinder axis 19b of the damping cylinder 19 and at a distance to this transverse to the pivoting plane of the support arm 1' runs. The symmetrical to the furniture hinge pivoting flap 49 also has a stop surface 25 on that with the stop tab 26 ' on the back 46 of the support arm 1' engages.

As can be seen in particular from the 24 . 26 and 27 detects, is the pivot axis 50 the swing flap 49 at the top of the Einstecktopfes 2 and approximately cuts the central axis 51 of the plug-in pot 2 , The swing flap 49 is on both sides of the support arm 1' on the door hinge part 2a pivoted. To stand out from the two with the inner pot 6 of the plug-in pot 2 connected side flanges 15 and 16 tabs 52 to the top, in each case a bearing pin 53 the swing flap 49 is stored. The two bearing pins 53 aligned with each other and form the pivot axis 50 ,

In most applications, it is sufficient and it is expedient that only the one dowel hole 17 a single damping cylinder 19 receives. The other dowel hole 13 then takes a dowel in a conventional manner 12 on. Instead, when running after the 24 - 27 but also be provided that both dowel holes 13 and 17 one damping cylinder each 19 take up. The swing flap 49 then rests on the piston rods 24 the two damping cylinders 19 from.

26 shows the position of the support arm 1' before the end of the closing movement of the furniture door at the beginning of the damping process. The stop tab 26 ' meets the stop surface of this still raised pivoting flap 49 on the extended piston rod 24 of the damping cylinder 19 rests.

In a further relative pivoting of the door stop member relative to the support arm 1' pushes the stop tab 26 ' the swing flap 49 in the in 27 shown position, wherein the piston rod 24 in the damping cylinder 19 is moved in and thereby opposes the movement of a damping force.
