A height-adjustable screw (15) for fixing and adjusting the height of the upper part on the lower part has at least one cam disk (43, 44) with an angle-dependent, radially changing slide face interacting with at least one slide face (52, 53) of an associated slide cam (49, 50) of the upper part. Preferred Features: The height-adjusting screw has a screw head (40) with a tool recess and a bolt-like part (41) on the opposite end to the screw head.

Description

The invention relates to a hinge with a height adjustment screw, in particular for furniture hinges according to the preamble of claim 1.

Such a mounting plate is known from DE 199 20 137 A1. The The present invention makes full reference to this Documentation, so that all the features shown there are also available here should.

DE 199 20 137 A1 describes a furniture hinge with one on one Articulated pot attached hinge arm or hinge strap shown, the Hinge arm adjustable via a shelf with one on the furniture body attached base plate is connectable, and to establish a connection Snap connection is provided. The shelf is as one piece, partially resilient snap-in part formed on the one hand by means of hook-shaped Legs can be attached to the base plate and legs on the other has, when pressure on the plate due to a suitable means forced displacement movement of the positioning plate relative to the base plate in associated locking tabs of the base plate engage, the resilient part of the Base plate secures the connection against further shifting.

In DE 199 20 137 A1, the base plate is formed in two parts, with a lower part that can be attached to the furniture body and one with the lower part by means of a clamping screw clampable upper part, the setting plate and the upper part when pressure on the shelf due to a suitable means forced displacement movement of the positioning plate relative to the base plate at least three mount points are connected, and the Connection against a spring element arranged on the positioning plate against further moving is secured. The height adjustment of the furniture door is done by loosening the clamping screw between the upper and lower part of the Base plate, moving the upper part on the lower part and locking again the clamping screw.

The two-part mounting plate described above has the disadvantage that at Loosen the clamping screw, the hinge connection between the upper part and Lower part of the base plate detaches in such a way that the furniture door can be removed with the entire Hinge, except for the lower part of the base plate on the furniture body, through the Dead weight of the furniture door moved downwards with the direction of gravity. This means that the hinge can be adjusted vertically and precisely Height direction not possible, because the height setting is not guided and by means of moving the upper part of the base plate the upper part of the base plate.

Furniture hinges already have a large number of different ones Adjustment options provided.

So there is an adjustment in the adjustment of the position of the Hinge arm relative to the mounting plate in the direction of the furniture joint, d. H. a Lateral adjustment of the furniture door. This adjustment is made by the so-called Side adjustment screw reached in a thread of the hinge arm stores and is held with her head in a recess of the mounting plate. Depending on the rotation of the screw, the hinge arm rises more or less from the mounting plate so that there is a lateral adjustment of the furniture door results.

Another adjustment option concerns the depth adjustment of the Hinge arm, through which the distance of the furniture door to the front of the Furniture is adjustable, as is known for example from DE 298 11 793 U1 is. The depth adjustment is generally done with a clamping screw, through which the hinge arm is attached to the mounting plate. The The clamping screw protrudes through an elongated hole in the hinge arm, the Depression is done by sliding along the slot and the Depth adjustment path is determined by the length of the elongated hole.

However, the known adjustment devices have considerable disadvantages.

With regard to the side adjustment of the door, the hinge arm is through Turning the side adjustment screw pivoted about an imaginary axis, so that the adjustment movement takes place along an arc of a circle. Thereby not only adjusts the side position of the door, but also in unintentionally the depth position of the door, so that the distance of the Door changed from the front edge of the furniture.

The problem with depth adjustment is that the depth adjustment screw must be solved in order to shift along the elongated hole enable. A sensitive setting is not possible.

A hinge with compensation function for the side adjustment is in the DE 299 14 473 U1. It is at least one swivel lever provided that is pivoted when turning the side adjustment screw and on which the hinge arm is supported indirectly or directly, wherein the hinge arm when turning the joint adjustment screw through the at least one pivot lever is guided parallel to the base plate. This one The construction presented, however, appears to be very complex to manufacture.

However, no suitable height adjustment of the Known hinge or the furniture door to the furniture body.

The present invention is therefore based on the object Mounting plate for furniture hinges avoiding the above Develop disadvantages such that a guided and smooth Height adjustment of the hinge or the furniture door to the furniture body is made possible.

This object is achieved by the technical teaching of claim 1.

The invention is based on the fact that the base plate consists of at least two parts is formed with an upper part and a lower part, and for fixing and Height adjustment of the upper part on the lower part a height adjustment screw is provided which has at least one eccentric or cam disc has an angle-dependent change in the radius, which eccentric or Cam with at least one associated slide cam of the upper part interacts.

For the side adjustment, the height adjustment screw has at least an eccentric or cam disc, the rotation of the Height adjustment screw a transverse displacement of the upper part of the base plate to the fixed lower part of the base plate.

The advantage here is that the hinge cannot be adjusted automatically, since the cams of the clamping according to the invention Height adjustment screw, which the two components of the base plate top and Bottom clamped together, are self-locking. This height adjustment is smooth and easy to operate even with heavy furniture doors.

The height adjustment screw passes through a corresponding hole in the Upper and lower part of the base plate and lies with its lower eccentric or Cam on the surface of the upper part of the base plate on and is prevented from falling out by a screw base, which was preferably attached by means of a wobble process. Before assembly is the height adjustment screw on the opposite of the screw head Side with a bolt, which has a smaller diameter has, like the holes of the upper and lower part of the base plate. To Insert this bolt of the height adjustment screw in both congruent holes of the upper and lower part of the base plate then the bolt stumbled from below, thus designed as a kind of rivet head.

In other embodiments of the invention, the height adjustment screw can also be threaded at its bolt end and under the lower part of the base plate with e.g. self-locking nut secured his.

Versions with locking rings or split pins are also provided, or with a lower expansion of the bolt-side end of the Height adjustment screw for securing to the underside of the lower part of the Baseplate.

The eccentric or cam disc acts with a sliding cam on the Upper part of the base plate together, which slide cam prefers inside a recess is arranged in which the eccentric or Cam and also the head of the height adjustment screw for protection and can be included to save space. The slide cam includes one Stop surface for limiting the angle of rotation of the Height adjustment screw, which twist angle is typically around 330 °. Furthermore, the sliding cam has a radially narrow set to the sliding surfaces of the eccentric or cam disc. It is preferred that two such sliding cams are present, which are approximately mirror symmetrical are arranged to the longitudinal center axis of the base plate parts, that is, to each other offset by approx. 180 ° and reversed. Of course, here are the Stop surfaces to limit the angle of rotation of the height adjustment screw directed in the opposite direction, i.e. the one for a clockwise stop and the other for a counterclockwise stop.

The with the stop surfaces and sliding surfaces of this cam (s) interacting stop surfaces and sliding surfaces of the eccentric or Cam (s) is along the lateral surface of the height adjustment screw arranged and in cross section through the height adjustment screw as preferred to look about partly crescent-shaped. The first end of this cam sickle is there radially expanding in harmony, whereas the second end this cam sickle abruptly from the maximum radius back to one smaller radius, which e.g. is as large as the radius of the first End of the cam sickle, so about the radius of the bolt-shaped part of the Height adjustment screw corresponds. Here increases in the radius Sickle part e.g. about 180 °, other angular degrees also being conceivable.

If several cams are provided, they are at different levels arranged one above the other and offset at an angle to each other or to each other mirrored to the transverse axis of the height adjustment screw. With e.g. two cams with each 180 °, these are preferably arranged in two planes and during the first If the height adjustment screw turns to the left, the cam will run up Has cam, the other cam has a running cam, the Stop faces and sliding surfaces, however, in the same angular range Height adjustment screw are provided.

The stop surface of the cam can vary from the maximum radius deflection in the Angle of 90 ° directly in the radial direction to the nominal width of the bolt part of the Height adjustment screw go back, or at an angle to it, as e.g. in the obtuse or acute angle, depending on the function, so in the case of an obtuse Under certain circumstances, turn the height adjustment screw with increased effort is possible, or almost at an acute angle backlash-free form fit with the corresponding counter surface on the upper part of the Base plate becomes possible.

The height adjustment screw therefore preferably has two counter-rotating, superimposed cams. By the opposite Cam disks are roughly opposed to doubling the travel range achieved for using only one cam.

That on the upper part of the base plate has a recess in which Contact surfaces (stop and sliding surfaces) for the two cams in Form of cams are formed.

The invention is described below using an exemplary embodiment Reference to several drawings explained in more detail. From the drawings and their description goes further features and advantages of the invention out.

Figure 1 shows the top view of the furniture hinge according to the invention in assembled and assembled state, Figure 2 is the bottom view see this in longitudinal section. These two Figures 1 and 2 are used only for Overview of the location and construction of the invention Furniture hinge.

On a furniture door 28 is a hinge cup 30 by means of a corresponding Fixing screws set within a recess. This Hinge cup 30 is connected to a conventional hinge strap 31 conventional hinge arm 32, which is connected via a horizontal Adjusting screw 36 (side adjustment) and a locking screw 37 with the Setting plate 27 is connected. The setting plate 27 with spring 33 and handle 34 in turn is clipped onto the upper part 3 of the base plate 1, as with the DE 199 20 137 A1 already shown. The upper part 3 is now over corresponding Snap connections (Figure 10) connected to the lower part 2 of the base plate 1, which lower part 2 is screwed onto the furniture body 29.

The setting plate 27 consists of an essentially U-shaped, elongated one-piece part, preferably a metal part. From the shelf 27, a spring clip 33 is formed in one piece, the leg of which is approximately in attack the central area of the long sides of the shelf and move backwards continue over the end of the shelf, where it can be moved through a handle 34 are connected, which forms the rear end of the spring clip 33 in order to be able to operate the spring clip by hand.

The upper part 3 has left and right at its rear end Latching steps 35, which for latching the rear sections of the Spring clip 33 serve. These locking levels 33 are to compensate for play provided and ensure a play-free or almost play-free engagement of the spring clip 33 on the upper part 3.

Figure 10 shows an exploded view of the structure of the base plate 1 of the Mounting plate, consisting of a lower part 2, with which an upper part 3 is connected. The lower part 2 has an approximately 45 ° at the front end Notch 4 angled at the top and one at the rear end corresponding, about 45 ° protruding pin 6. The notch 4 and the Pins 6 are assigned corresponding slopes 5, 8 of the upper part 3, wherein the upper part 3 is suspended in the lower part 2 so that the notch 4 and the pin 6 on the assigned slopes 5, 8. It takes effect the pin 6 is through an opening 7 of the upper part 3. On the lower part 2 at least one guide groove 9 is provided, in which when inserted Upper part 3 engages an associated guide cam 10 and so the situation between the components 2,3 in the longitudinal direction. In the present example an additional guide groove 11 is arranged on the upper part 3, which with a corresponding guide cam 12 of the lower part 2 cooperates.

The lower part itself is screwed or the like, which in engage associated holes 18, 19, attached to the furniture body.

On the lower part there is also a fail-safe device 13 in the form of a rag arranged, which after assembly of the upper part 3 on the lower part 2 is pressed up and thereby on an assigned surface 14 of the Upper part creates, so that a shift between lower part 2 and upper part 3 is no longer possible. This failover 13, 14 is used to Lower part 2 and the upper part 3 to keep connected, even if the provided height adjustment screw 15 which through an opening 16 of the Upper part 3 engages in an associated bore 17 in the lower part 2 and there is stuck, is defective. The height adjustment screw 15 can Upper part 3 can be moved laterally on the lower part 2 and the position is determined by the self-locking of the eccentric or cam discs the height adjustment screw 15 locked.

Furthermore, you can also see various suspension devices for attaching the Setting plate 27 on the base plate 1 or the upper part 3 of the base plate 1. For this purpose, the upper part 3 has lateral depressions 21 in the front area, which, as can be seen in connection with FIG. 5, for hanging in assigned hooking cams 28 serve. The hooking cams 28 are off molded from the material of the setting plate 27.

FIG. 10 thus shows an exploded view of the individual parts of the Mounting plate, consisting of the base plate 1, which consists of a Bottom part 2 and an upper part 3, the height adjustment screw 15th to determine the lateral position of the connection between lower part 2 and Upper part 3 and the setting plate 27, not shown here, on the upper part 3 of the base plate 1 is hooked in and locked.

FIG. 9 shows, like FIG. 10, the structure of the base plate 1 of the mounting plate, consisting of a lower part 2, to which an upper part 3 is connected, however in longitudinal section and in assembled condition. You can see that Fail-safe 13, which is installed on the lower part 2 after the installation of the upper part 3 is bent upward in the direction of arrow 20, so that the tab 13 is attached of the assigned surface 14 of the upper part.

Figure 3 also shows the structure of the base plate 1 of Figure 9 Mounting plate, but the bottom view not cut.

Figures 4, 7 and 8 show a top view of the assembled Base plate 1, the representations of FIGS. 4 and 7 being identical, however, FIG. 7 shows an enlargement and the upper part 3 to the lower part 2 in shows a center position. The two longitudinal center axes of the upper part 3 and of the lower part 2 thus overlap in the top view. This is through vertical adjustment movements 38, 39 by means of the height adjustment screw 15 accomplished.

Figure 8 shows, however, that by turning the height adjustment screw 15 in Clockwise 51 to the right a height difference H by a vertical Adjustment movement 39 was reached upwards, so that the upper part 3 to Lower part 2 of the base plate 1 is offset by the amount H upwards. This corresponds to a stroke of the door by this amount H, which is typically around +/- 1.5 mm lies.

In Figure 7, the middle position between the upper and lower part of the Base plate 1 shown what by pressing the height adjustment screw 15 in Direction of rotation 51 and opposite can be achieved. In the middle position are the cams 49, 50 with their sliding surfaces 52, 53 in the initial region of the assigned sliding surfaces 45, 46. By turning the Height adjustment screw 15 in the direction of rotation 51 clockwise to The lower stop surface 48 of the lower stop then comes as shown in FIG Cam 44 in abutment with the associated abutment surface 55 of the lower cam 50. The upper cam 43 is now in the relative position to the upper cam 49 that the sliding surface 52 of the upper cam 49 in Area of the end of the sliding surface 45 of the upper cam 43 to lie comes, that is in the area of the stop surface 47 of the upper cam 43.

Conversely, turning the height adjustment screw 15 would counter the direction of rotation 51 counterclockwise up to the stop the upper Stop surface 47 of the upper cam 43 in contact with the assigned stop surface 54 of the upper cam 49 come. The lower one Cam 44 would now be in the position relative to lower cam 50, that the sliding surface 53 of the lower cam 50 in the region of the end of the The sliding surface 46 of the lower cam 44 comes to rest, that is to say in the region the stop surface 48 of the lower cam 44.

Figures 5, 6 and 11 now show the invention Height adjustment screw 15 in a tangled and brewed state, whereby 5 is a radial view, FIG. 6 is an axial view and FIG. 11 is a view represents perspective view from the foot.

The approximately pin-shaped height adjustment screw 15 has one upper screw head 40, at the bottom two Cam discs 43, 44, a bolt-shaped part 41 and the vertaumelte Connect screw foot 42. In the original state before assembly, the Height adjustment screw 15 as shown in Figure 10, namely without screw base 42, which only after inserting the bolt-shaped Part 41 through the overlapping holes 16, 17 of the upper and Lower part of the base plate 1, is messed up from below and so its 5, 6, 9 and 11 receives foot shape.

As can be seen in FIG. 6, the cam disks 43, 44 can be seen in the two same quadrant of the height adjustment screw 15 arranged, ie in same semicircle, but they are opposite to each other. So in Figure 6 the height adjustment screw 15 turned in the direction of rotation 51 to the right, then runs the upper cam 43 with its upper sliding surface 45 on the Sliding surface 52 of the associated cam 49 of the upper part 3, whereas at the same time the lower cam 44 with its lower sliding surface 46 the sliding surface 53 of the associated cam 50 of the upper part 3 runs. at maximum possible rotation in the direction of rotation 51 to the right then beats the Height adjustment screw 15 with the lower stop surface 48 of the lower Cam 44 on the associated stop surface 55 of the lower Cam 50 on. Similarly, the height adjustment screw 15 strikes with the upper stop surface 47 of the upper cam 43 on the associated Stop surface 54 of the upper cam 49 when the height adjustment screw 15 was rotated at most against the direction of rotation 51.
