The adjustment has a side-adjustment screw (13) with at least one cam disc (15), effecting a side and parallel displacement of the hinge arm in relation to the mounting plate and thereby correcting the depth of the door (12). The cam disc, incorporating a cam bearing, cooperates with a bearing plate (3) fixable between the hinge-arm and the mounting plate.

Description

The invention relates to a furniture hinge with an adjusting device for one indirectly or directly on a one-piece or multi-piece piece of furniture Mounting plate mounted hinge arm according to the preamble of independent claims.

In general, there are various adjustment options for furniture hinges intended.

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, i.e. 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. The depth adjustment is generally done with a Clamping screw through which the hinge arm on the mounting plate is attached. The clamping screw protrudes through an elongated hole in the hinge arm, the depth setting is made by sliding along the slot and the Depth adjustment path is determined by the length of the elongated hole.

A furniture hinge of the type mentioned above is e.g. from DE 298 11 793 U1 known.

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. 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 However, the construction presented appears to be very complex to manufacture.

The object of the invention is to propose a furniture hinge that over has improved setting options without excessive Design and manufacturing effort is necessary.

This task is solved by the characteristics of the independent Patent claims.

For the side adjustment, the side adjustment screw has at least one Eccentric or cam disc, the rotation of the Lateral adjustment screw is a lateral adjustment and at the same time a parallel one Displacement of the hinge arm relative to the mounting plate and thus one Correction of the depth adjustment of the door by an amount K.

The invention has the advantage that when installing the Hinge with the depth adjustment device set gap width S constant remains, even if the joint width F varied.

The thread of the side adjustment screw sits in a corresponding one Threaded hole in the hinge arm.

The eccentric disc cooperates with a bearing plate that is relative to Mounting plate lockable between the hinge arm and the mounting plate is arranged. The bearing plate comprises an eccentric bearing on which the Eccentric disc is supported so that when the side adjustment screw is actuated a side adjustment perpendicular to the mounting plane of the hinge arm and a displacement of the hinge arm on the bearing plate or Mounting plate is done.

In another preferred embodiment, the Lateral adjustment screw two approximately opposite, one above the other Cam discs on.

The bearing plate has an opening, the contact surfaces for the two Cam forms.

For this purpose, an offset is provided on the bearing plate, which results in two levels of superimposed contact surfaces for the cams result.

Due to the opposing cam discs, the Travel in contrast to the use of only one cam.

In order to adjust the depth of the Reaching the hinge arm is the eccentricity of the eccentric or Cam on the pitch of the thread of the side adjustment screw Voted.

For depth adjustment, the depth adjustment screw on the hinge arm or one, connected to this, mounted component and has at least one Eccentric or cam disc, which are on assigned contact surfaces of the Supported mounting plate and a when the depth adjustment screw is turned Displacement of the hinge arm relative to the mounting plate by an amount W causes.

This has the advantage that when installing the hinge by means of Depth adjustment screw set the gap width S quickly and sensitively can be. In the prior art, it was common to use the depth adjustment screw to form as a clamping screw running in an elongated hole, which loosened had to be so that the hinge arm could be adjusted.

Furthermore, the mounting plate preferably comprises a base plate and a Setting plate, the setting plate being releasably connected to the base plate can.

The depth adjustment screw 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.

The depth adjustment screw is rotatably mounted in a bearing plate and passes through an opening provided in the setting plate, the Forms contact surfaces for the cam disc (s) of the depth adjustment screw. So that there are suitable contact surfaces for both cams, the shelf includes a bend, which is divided into two levels result in superimposed contact surfaces for the cams.

In this way, by pressing the depth adjustment screw Displacement of the bearing plate and the hinge arm connected to it opposite the shelf.

Preferably, the bearing plate comprises bearing tabs that are associated with Engage the guide slots of the hinge arm and slide them into it are led. The bearing lobes also act as a pivot bearing around its axis the hinge arm rotates during a side adjustment.

Several embodiments of the invention are described below with reference to Drawing figures described in more detail. From the drawings and their Description results in further features, advantages and Applications of the invention.

A first exemplary embodiment of the invention is shown in FIGS. 1 to 7A shown.

The furniture hinge comprises a mounting plate consisting of a Base plate 1 and a set plate 2, the base plate 1 on the Side wall of the furniture box 11 is attached. The setting plate 2 can rest and releasably connected to the base plate 1. On the shelf 2 is the Hinge arm 8 attached, which continues to the left in the drawing and articulated with a stop part on the door, e.g. a hinge cup 10, is connected, which is embedded in the furniture door 12. For side adjustment the furniture door 12, i.e. to adjust the hinge arm 8 in the direction of Mounting level or base plate 1 is a side adjustment screw 13 intended.

The depth adjustment, that is, the adjustment of the hinge arm 8 parallel to Base plate 1 takes place by means of a depth adjustment screw 17, the thread of which in an associated receiving thread engages in the setting plate 2. Will the seat the depth adjustment screw 17 loosened somewhat, the hinge arm 8 in Arrow direction 22 are shifted until the gap S has the desired value having. By tightening the depth adjustment screw 17, the Hinge arm 8 locked in the preset position.

The side adjustment screw 13 shown in FIG. 6 is 16 in with its thread a threaded bore of the hinge arm 8 is supported and supported with her Screw head 14 on an assigned contact surface of the setting plate 2. The hinge arm can now be turned by turning the side adjustment screw 13 8 in the direction of arrow 21, e.g. when turning to the right into a position like her is shown in dashed lines in Figure 1.

As a result, the furniture door 12 also moves upward in the direction of the arrow 21, the gap F increases. But now that the hinge arm 8 at Lateral adjustment does not perform a pure lifting movement in the direction of arrow 21, but a swivel movement, there is a circular movement by one imaginary axis with a center at about reference number 7, so that the Adjustment movement takes place along an arc 20 with a radius 18. Thereby there is not only an adjustment of the joint width F, but at the same time an undesirable enlargement of the gap S by the amount K.

This undesired depth adjustment movement is according to the invention counteracted by the side adjustment screw 13 with a Eccentric disc 15 is provided, which with an eccentric bearing 4 in one Bearing plate 3 interacts (Figure 6). The bearing plate 3, which in FIGS and FIG. 7A is arranged between the hinge arm 8 and the setting plate 2 and normally fixed by the clamping action of the depth adjustment screw 17 connected to the setting plate 2. However, the hinge arm 8 is in the direction of the arrow 22 slidably guided on the bearing plate 3, on the one hand by the Side adjustment screw 13 and the other through guide slots 9 in Hinge arm 8, into which associated bearing tabs 7 of the bearing plate 3 intervene so that a displacement in the direction of arrow 22, but also a Pivotal movement around the axis of the bearing tab 7 is possible.

The side adjustment screw 13 is rotatably supported and supported in the setting plate 2 with her head 14 on a contact surface of the setting plate 2. The Eccentric disc 15 interacts with the eccentric bearing 4 of the setting plate 3, the eccentric disc 15 assumes a basic position, as shown in FIG 2 is shown. Now there is a rotary movement of the side adjustment screw 13 to the right, the hinge arm 8 becomes upward due to the thread 16 lifted and at the same time the eccentric disc 15 pivots into a position as shown in Figure 3, the setting plate 3 together with the Hinge arm 8 shifted to the right by an amount K in the figure becomes. This amount corresponds exactly to the amount K in Figure 1, i.e. i.e. the undesired enlargement of the gap S by the amount K is caused by the Eccentric bearing of the side adjustment screw 13 counteracted and corrected.

A second embodiment of the invention is in Figures 8 to 12A shown. The side adjustment by means of side adjustment screw 13 and Bearing plate 3 is identical to that in connection with FIGS. 1 to 7 described, side adjustment.

The depth adjustment now has a special depth adjustment screw 23 on, which is shown in more detail in Figure 11. The depth adjustment screw 23 comprises two superimposed cams 24 and 25, which with in the setting plate 26 arranged contact surfaces cooperate. For this, the in the FIGS. 10 and 10A, the setting plate 26 shown a special opening 32 on, the contact surfaces 27 and 29 for the upper and lower cam 24, 25 forms. So that the contact surfaces 27, 29 each in the plane of assigned cam plate, the setting plate 26 includes a bend 28 down, which forms the lower contact surface 29. It close Stops 43, 44 on the contact surfaces 27, 29, which as Limit stop for the depth adjustment screw 23 serve. The The mode of action of the adjustment movement is shown in more detail in FIGS. 12 and 12A shown. The lower cam 25 of the depth adjustment screw 23 is supported in the position, according to FIG. 12, on the stop 44 of the offset 28 or is due to this. At the same time, the upper cam 24 lies with it Circumferential surface on the left stop 27 of the adjusting plate 26. The positioning plate 26 stands opposite the base plate 1, whereby - as already stated - the Bearing plate 3 together with the hinge arm 8 opposite the setting plate 26 in the direction of arrow 22. Now there is a rotation of the Depth adjustment screw 23 to the left, so the peripheral surface of the lower one slides Cam 25 along the contact surface 29 and is expressed there, so that the bearing plate 3 together with the depth adjustment screw 23 and the Move hinge arm 8 to the left by an amount W, the Depth adjustment screw can be turned until the upper one Cam 24 strikes the stop 43. In the same way, a Turning the depth adjustment screw 23 to the left so that the upper Cam 24 on the contact surface 27 repels, so that the Depth adjustment screw 23 together with the hinge arm 8 around the Amount W moves to the right until the lower cam 25 stops 44 triggers. This allows easy and sensitive depth adjustment achieve.

A third embodiment of the invention is shown in Figures 13 to 16A shown. The depth adjustment device with depth adjustment screw 23 is identical to the depth adjustment device in connection with the Figures 8 to 12A has been described. The side adjustment device includes According to the invention, a side adjustment screw 35, which, according to FIG two cams 36, 37 is equipped, similar to that Depth adjustment screw 23. The side adjustment screw 35 is also seated its thread 38 in the hinge arm 8 and is supported with its screw head 39 on an assigned surface of the setting plate 26. suitable Contact surfaces for the cam disks 36, 37 of the side adjustment screw 35 are formed by a modified bearing plate 33, the shape of which corresponds approximately to the bearing plate 3, according to FIGS. 7 and 7A, but in the area the side adjustment screw 35 has an opening 40 which Contact surfaces 41, 42 for the lower and upper cam 36, 37 of the Has side adjustment screw 35. Around the contact areas in two levels to offset against each other, an offset 34 projects into the opening 40, which forms the upper contact surface 42.

In contrast to the embodiment of a side adjustment according to figures 1 to 8 is a through the double cam of the side adjustment screw 35 more sensitive adjustment possible with less effort, because the slope of the Side adjustment screw 35 due to the larger adjustment range Double cam can be made much smaller than comparatively in the example according to Figures 1 to 8. Now the Side adjustment screw 35 is actuated, the hinge arm 8 rises accordingly from the setting plate 26, with the cams at the same time a sliding movement of the bearing plate 33, together with the Hinge arm 8 to cause the amount K, so that there is compensation for the otherwise undesirable change in the gap S (Figure 1) results.
