Abstract

Rotating the depth adjustment screw (8) once through 360 deg. corresponds to the maximum depth adjustment distance. The hinge has a hinge bracket (3) which can be mounted directly or indirectly on the furniture (31) and which has a single or multi-part base plate (1). A depth adjustment screw rotatably mounted in the base plate is joined to a follower plate (15), the latter being connected to the hinge bracket. The screw has actuator parts which cooperate with actuator surfaces on the follower plate. Rotating the screw causes the follower plate and hinge bracket to be displaced relative to the base plate.

Description

The invention relates to a furniture hinge with a depth adjustment for a directly or indirectly mounted on a furniture side, one or more parts mounting plate hinge bracket, according to the preamble of claim 1.

In general, different adjustment options are provided in furniture hinges.

Thus, there is an adjustment in the depth adjustment of the hinge bracket, by which the distance of the furniture door to the front side of the furniture is adjustable. The depth adjustment is generally carried out with a clamping screw through which the hinge bracket is mounted on the mounting plate.
The clamping screw protrudes through a slot in the hinge bracket, whereby the depth adjustment is made by sliding along the slot and the adjustment is determined by the length of the slot. The disadvantage here is that the depth adjustment must be solved to allow a shift along the slot. A sensitive adjustment is not possible.

The DE-U-299 14 473 discloses a furniture hinge with depth adjustment, which is based on the principle of a worm drive. Along the fixed mounting plate of the furniture hinge a plurality of arcuate tooth segments are arranged at a distance parallel to each other. With these toothed segments, a helical projection cooperates with a depth adjustment screw rotatably mounted in the hinge bracket.

By turning the screw, the projection engages successively in the tooth segments, whereby the hinge bracket shifts along the mounting plate. This depth adjustment offers a large adjustment and a sensitive adjustment, but has the disadvantage that several revolutions of the adjustment are necessary to use the entire adjustment.

The EP 0 982 455 A teaches a furniture hinge with the features of the preamble of claim 1, with a depth adjustment, the actuator is formed by an eccentric, which acts on corresponding shelves of an intermediate piece in the hinge, so that the hinge arm is moved. The maximum adjustment results from a rotation of the eccentric screw by 180 °.

It is an object of the invention to provide a furniture hinge with depth adjustment, which has the largest possible adjustment. Furthermore, the depth adjustment should be smooth, but exclude an independent adjustment of the depth position.

This object is achieved by the features specified in claim 1.

Ausgestaltende features of the invention are specified in the independent claims.

The invention is based on a furniture hinge with a driver plate which is connected to the hinge bracket, wherein the depth adjustment screw has adjusting elements which cooperate with associated mounting surfaces on the driver plate such that upon rotation of the depth adjustment screw, the driver plate and the hinge bracket with respect be moved to the mounting plate; A single turn of the depth adjustment screw over 360 ° corresponds to the maximum depth adjustment path.

In a preferred embodiment of the invention, the driver plate is approximately U-shaped in cross-section and has an upper and a lower driver leg, which are connected to one another at a side edge. Parts of the depth adjustment screw are arranged on or in the driver plate.

It is further provided that the shelves are formed on the free side edges of the Mitnehmerschenkel and each have a driver slot and an adjoining, in a stop bay passing rolling surface. The shelves of the Mitnehmerschenkel are formed such that the cam slot of a Mitnehmerschenkels the stop bay of the other Mitnehmerschenkels opposite and vice versa.

According to the invention, the adjusting elements are formed from two crank pins arranged on opposite sides of a concentric crank disk. The crank pins are offset by 180 ° to each other and extend parallel to the longitudinal center axis of the crank disc, wherein the longitudinal center axes lie in a plane.

According to the invention, it is provided that the upper crank pin is assigned to the footprint of the upper driver leg and the lower crank journal is assigned to the footprint of the lower driver arm. It always engages only one crank pin in the associated driver slot, while the other crank pin rests against the associated rolling surface or stop bay.
For fixed positioning of the depth adjustment screw whose crank disk is received in a bore of the actuator plate. The driver plate, however, is slidably mounted on the adjusting plate, wherein the crank disk and parts of the adjusting plate are arranged in the space between the Mitnehmerschenkeln.

In order for the hinge bracket to be entrained by the driver plate, the upper driver arm preferably has upwardly projecting tabs which engage in associated recesses of the hinge bracket.

The maximum achievable Tiefenverstellweg results from the double distance of the crank pin to each other. Consequently, a single revolution of the depth adjustment screw over 360 ° corresponds to the maximum depth adjustment path.

The invention has the advantage that with only one revolution of the depth adjustment screw, a sensitive adjustment of the depth position of the hinge bracket over its entire adjustment can be made. The proposed depth adjustment is smooth, but excludes an independent adjustment of the adjusted position.

An embodiment of the invention will now be explained in more detail with reference to the drawing figures. From the drawings and the description below there are further features, advantages and applications of the invention.

In the Figures 1 and 2 the basic structure of the furniture hinge according to the invention is shown. The furniture hinge comprises a mounting plate, consisting of a base plate 1 and a setting plate 2, wherein the base plate 1 is fixed to the side wall of a piece of furniture 31. The adjusting plate 2 can be locked and releasably connected to the base plate 1. On the adjusting plate 2, a hinge bracket 3 is fixed, which continues in the drawing to the left and hinged to a door-side stop member, z. B. a hinge cup (not shown), which is embedded in a furniture door (not shown).

For adjusting the side of the furniture door, d. H. for adjusting the hinge bracket 3 in the direction perpendicular to the mounting plane or base plate 1, a side adjustment screw 8 is provided. The depth adjustment, d. H. the adjustment of the hinge bracket 3 parallel to the base plate 1, by means of a depth adjustment screw 9, which is preferably rotatably mounted in the mounting plate of the adjusting plate 2.

The depth adjustment screw 9 is together with a driver plate 15 which is connected to the hinge bracket 3, wherein the depth adjustment screw 9 has adjusting elements which cooperate with associated shelves on the driver plate 15 such that upon rotation of the depth adjustment screw 9 in the direction of arrow 32, the driver plate 15 and the Hinge bracket 3 with respect to the mounting plate 1, 2 is moved in the direction of arrow 33. The maximum possible adjustment of the depth adjustment is defined by the distance s.

The driver plate comprises an upper driver leg 16 which comes to rest between the hinge bracket 3 and the actuator plate 2 and a lower driver leg 17, which lies between the actuator plate 2 and the base plate 1.

In FIG. 4 the structure of the depth adjustment is shown in detail. The depth adjustment screw 9 comprises a screw head 10, an adjoining collar 11 and an upper crank pin 13, which is arranged eccentrically to the longitudinal central axis of the screw 9. At the upper crank pin 13, a crank disc 12 connects, which in turn is arranged concentrically to the screw longitudinal center axis. Finally, the screw 9 comprises a lower crank pin, which is arranged eccentrically to the screw longitudinal center axis and with respect to the upper crank pin 13 is offset by 180 °.

The driver plate 15 comprises an upper driver leg 16 and a lower driver leg 17, which are connected to one another at one of its side edges, so that there is a part approximately U-shaped in cross-section. At the upper Mitnehmerschenkel upwardly directed tabs 19, 20 are provided.

The hinge bracket comprises according to FIG. 3 a front opening 4, in which the side adjustment screw is mounted, and a rear slot-shaped opening 5, which has recesses 6, 7 at its longitudinal ends. In the opening 5, the depth adjustment screw 9 is inserted. How to get out of the FIGS. 3 and 4 in conjunction with the Figures 1 and 2 can recognize, sits the crank disk 12 in a bore 27 of the adjusting plate. 2

The driving plate 15 is pushed onto the surface of the adjusting plate 2 such that the upper driving leg above the adjusting plate 2 and the lower driving leg 17 below the adjusting plate 2 comes to rest, wherein the crank disk 12 is received in the intermediate space 18 between the legs 16, 17. The upper crank pin 13 is in this case on the irregular footprint of the upper Mitnehmerschenkels 16, whereas the lower crank pin 14 rests against the footprint of the lower Mitnehmerschenkels 17.

Now, the hinge bracket 3 can be placed, the depth adjustment screw 9 passes through the slot 5 of the hinge bracket and rests with its collar 11 at the slot edge. The tabs 19, 20 of the driver plate 15 engage in the recesses 6, 7 of the elongated hole 5 a.

The FIGS. 5 to 7 once again show the depth adjustment screw 9 inserted into the driver plate 15 in all three views. It can be seen the crank plate 12 which is received between the Mitnehmerschenkeln 16 and 17 and the crank pin 13, 14 which rest against the free edges of the Mitnehmerschenkel 16, 17. The crank pins 13, 14 have a mutual distance d, wherein the maximum Tiefenverstellweg s twice the distance d corresponds, as will be explained below. The longitudinal center axes 28 to 30 of the depth adjustment screw 9 and the crank pins 13 and 14 are parallel to each other and in a plane.

Based on FIGS. 8 to 17 The operation of the depth adjustment will now be described. It is important that the driver plate 15 is fixedly connected to the hinge bracket 3, since the tabs 19, 20 engage in the associated recesses of the hinge bracket 3, whereas, however, the depth adjustment screw 9, which here has the crank plate 12 and the crank pins 13 and 14, is fixedly mounted in the bore 27 of the adjusting plate 2. Upon rotation of the depth adjustment screw 9, not the screw shifts itself, but the driver plate 15 moves relative to the depth adjustment screw 9 and with it the hinge bracket. 3

The FIGS. 8 and 9 show the depth adjustment in its initial position, ie 0 ° position. Here, the lower crank pin 14 is in engagement with a driver slot 21 which is formed on the lower Mitnehmerschenkel 17. The upper crank pin 13 is located in a stop bay 26, which is part of the upper Mitnehmerschenkels 16.

Now, if the depth adjustment screw 9 is rotated counterclockwise, so turn with her the crank plate 12 and attached to her crank pin 13, 14. In 90 ° position, as it FIGS. 10 and 11 show, the lower crank pin is still in engagement with the cam slot 21, whereas the upper crank pin 13 runs freely and is not in engagement with the footprint 24 to 26 of the upper Mitnehmerschenkels 16. As a result, the driver plate 15 is carried along by the lower crank pin 14 and moves forward in the indicated arrow direction 33. The crank pin 13 runs freely along the rolling surface 25 in the direction of the upper drive slot 24.

When rotated by 180 ° according to FIGS. 12 and 13 the lower crank pin 14 is still in engagement with the lower driver slot 21 and transports the driver plate 15 in the direction of arrow 33. The upper crank pin 13 has now moved along the rolling surface 25 and now comes into the area of the upper driver slot 24 and engages in this , At the same time pivots the lower crank pin 14 gradually out of the lower drive slot 21.

Continue until you reach the 270 ° position in the FIGS. 14 and 15 is shown, it can be seen that the lower crank pin 14 now along the lower rolling surface 22 along, while the upper crank pin is still in engagement with the upper cam slot 24 and the drive plate 15 in the direction of arrow 33 on.

Finally, in the 360 ° end position, which is in the FIGS. 16 and 17 is shown, the upper crank pin is still in the drive slot 24 and has so far transported the driver plate 15, whereas the lower crank pin 14 has traveled along the lower rolling surface 22 and now strikes in the lower stop bay 23.

As you can see, the drive plate 15 was transported in a complete rotation of the depth adjustment screw 9 by the crank pins 13 and 14 continuously in the direction of arrow 33. In this case, the drive plate 15 is transported over the first half of the adjustment path s from the lower crank pin 14 and over the other half of the adjustment path s from the upper crank pin 13. The total displacement s therefore corresponds to twice the distance d of the crank pins 13, 14, since each crank pin transports over a distance corresponding to the distance d.
