Description:
BACKGROUND OF THE INVENTION  
         [0001]    The invention relates to a hinge for furniture with a frame and with a door wing secured to the frame, with a bedplate which is to be fitted to the frame and which carries an intermediate piece and a hinge arm, with a joint-adjustment screw and a device for the depth adjustment of the hinge arm.  
           [0002]    In modern furniture construction, so-called door frames are sometimes used, these frames, as a stable part of the item of furniture, carrying the hinges for the door wings, while the actual side walls of the body of the furniture are made from weaker material. This brings with it the advantage that either the overall costs of the item of furniture can be reduced, or higher-quality and thus optically more attractive materials can be chosen for the side walls without the item of furniture being more expensive compared with furniture produced by conventional means.  
           [0003]    Such a hinge is known for example from the Austrian utility model AT 1385 U1.  
           [0004]    In the case of such hinges, it is known to provide the bedplate with an oblong hole aligned vertically in mounting position, in order to make possible a height adjustment of the door wing. For this, however, the fixing screw must be loosened and the door wing is raised or lowered together with the hinges attached to it. Once the height positioning has taken place, the fixing screws of the hinges must be tightened again. In particular in the case of larger and heavier door wings, it is difficult to find the right height position for the door wing.  
         SUMMARY OF THE INVENTION  
         [0005]    The object of the invention is to improve a hinge of the type mentioned at the outset such that a more comfortable height adjustment of the door wing is made possible.  
           [0006]    The object according to the invention is achieved in that, for the height adjustment of the hinge arm relative to the bedplate in one of the parts bedplate, intermediate piece, hinge arm, a rotatable part is housed via which the intermediate piece and/or the hinge arm can be shifted relative to the bedplate.  
           [0007]    The rotatable part can for example be designed as an eccentric or else as an annular disk which has, on one side, a bar running in the form of a spiral against which at least one projection of a hinge part, such as bedplate, intermediate piece or hinge arm, rests. By way of example, the rotatable disk is held in the intermediate piece and the projections are provided at the bedplate. Upon turning of the disk, the intermediate piece is shifted together with the hinge arm relative to the bedplate.  
           [0008]    An embodiment of the invention provides that the bedplate, the intermediate piece and the hinge arm are connected by a pin aligned parallel to the axis of rotation of the hinge, and that the hinge arm can be shifted on the pin in its longitudinal direction, the joint-adjustment screw having, in a manner known per se, a threaded section, a neck and a head, and that the neck projects through an oblong hole in the bedplate, which hole is aligned parallel to the axis of rotation of the hinge.  
           [0009]    According to another embodiment of the invention, the disk has, at the seat for the adjustment tool, a cylindrical base which is accommodated in a circular recess of the intermediate piece.  
           [0010]    Another embodiment of the invention provides that the disk has, at the seat for the adjustment tool, a cylindrical base which is accommodated in a circular recess of the hinge arm. In this case, the projections are developed at the intermediate piece and upon adjustment the hinge arm is moved relative to the intermediate piece in the height of the item of furniture.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0034]    In FIG. 1, the door wing  1  is shown in the open position. The hinge  2  connects the door wing  1  to the frame  3  of the body of the item of furniture.  
         [0035]    In the embodiment according to FIGS.  1  to  16 , the hinge  2  consists of the bedplate  5 , an intermediate piece  4 , the hinge arm  7  and the hinge casing  6  on the door wing side. The hinge arm  7  is housed on the intermediate piece  4  and the intermediate piece  4  on the bedplate  5 . The hinge casing  6  is articulated to the hinge arm  7  by means of a hinge axle. The hinge axle is formed by one leg  11  of a U-stirrup  8 .  
         [0036]    The hinge casing  6  is inserted into a bore in the door wing  1  in mounting position and screwed to the door wing  1  by means of screws  9 .  
         [0037]    Two legged springs  13 , which exert a closure force, are housed at the hinge casing  6 . The legged springs  13  are housed on the second leg  18  of the U-stirrup  8 .  
         [0038]    The legs  12  of the legged springs  13  press on a control part  14  which is developed at the free end of the hinge arm  7 . The hinge casing  6  is held in the closure position by the legged springs  13 , or pulled into the closure position if the angle between the door wing  1  and the closure plane is very small.  
         [0039]    The bedplate  5  is housed directly against the frame  3  and is screwed to the frame  3  by means of a fixing screw  18  which projects through a hole  15  of the bedplate  5 . On the side facing the open door wing  1 , the bedplate  5  has two angled lugs  16  which rest against the frame  3  at the front in mounting position.  
         [0040]    At the rear of the frame  3 , the bedplate  5  is likewise provided with a lug which rests against the frame  3  at the back.  
         [0041]    Both the intermediate piece  4  and the hinge arm  7  are developed with U-shaped cross-section. In the rear region, the bedplate  5  has two upwardly bent butts  17  which project into the intermediate piece  4 . The side bars  4 ′ of the intermediate piece  4  and the side bars  7 ′ of the hinge arm  7  point towards the bedplate  5 . The upwardly bent butts  17  of the bedplate  5  are provided with holes  19  which are designed as bores or punched holes. The side bars  4 ′ of the intermediate piece  4  also have circular holes  20  and the side bars  7 ′ of the hinge arm  7  oblong holes  21 . The intermediate piece  4  and the hinge arm  7  are connected to the bedplate  5  by means of a pin  22  which projects through the holes  19 ,  20 ,  21 .  
         [0042]    Housed in a rear opening  28  of the intermediate piece  4  is an eccentric  29 , the eccentric cam  30  of which is arranged within an oblong hole  31  of the hinge arm  7 . Through turning of the eccentric  29 , the position of the hinge arm  7  can be adjusted over the length of the oblong holes  21  in the direction of the depth of the item of furniture.  
         [0043]    If the position of the door wing  1  is to be adjusted in the direction of the furniture joint, the joint-adjustment screw  24  is turned and thus the hinge arm  7  is tilted about the pin  22 .  
         [0044]    The joint-adjustment screw  24  has a threaded section  23 , a neck  25  and a head  26 . The bedplate  5  is provided with an oblong hole  27 , the intermediate piece  4  has a circular hole  32  and the hinge arm  7  an oblong hole  33 , open to the rear, which opens into a further oblong hole  34 .  
         [0045]    The joint-adjustment screw  24  projects with its neck  25  through the circular hole  32  in the intermediate piece  4  and the oblong hole  27  in the bedplate  5 , and is riveted with its head  26  beneath the bedplate  5 .  
         [0046]    The opposite-facing rims  35  of the oblong hole  33  engage in the thread of the threaded section  23  of the joint-adjustment screw  24 . In order to facilitate this engagement, the rims  35  are offset in the direction of the length of the joint-adjustment screw over the height of a thread pitch. Because the joint-adjustment screw  24  is accommodated with its threaded section  23  in the oblong hole  33 , the depth adjustment of the hinge arm  7  is not impeded by the joint-adjustment screw  24 .  
         [0047]    The oblong hole  34  makes possible the suspension of the joint-adjustment screw  24  into the oblong hole  33 . The oblong hole  34  also allows access of an adjustment tool to the fixing screw  18  and to the spiral disk  10 , which serves for the height adjustment of the hinge arm  7 . The spiral disk  10  is provided, at its side facing the bedplate  5 , with a spiral projecting bar  36 . The projecting bar  36  lies against projections  37  of the bedplate  5  in mounting position.  
         [0048]    On its side lying opposite the spiral projection  36 , the spiral disk  10  has a cylindrical base  38  which is accommodated in a circular recess  47  of the intermediate piece  4 . A seat for an adjustment tool, preferably for a Phillips turnscrew, is located in the base  38 .  
         [0049]    The height adjustment of the hinge arm  7  and thus of the door wing  1  takes place simply by turning of the spiral disk  10 . No clamping screw needs to be loosened and then re-tightened. Because the spiral projection  36  is developed in self-locking manner, the door wing  1  is also prevented from dropping.  
         [0050]    Through turning of the spiral disk  10 , the intermediate piece  4  is shifted together with the hinge arm  7  in the direction of the pin  22  on the latter. This adjustment movement can be followed by the joint-adjustment screw  24  within the oblong hole  27  of the bedplate  5 .  
         [0051]    In the embodiment according to FIGS.  12  to  16 , the height adjustment of the hinge arm  7  takes place through an eccentric  49 . The hinge casing  6  and its connection to the hinge arm  7  as well as the closure mechanism are developed in the same way as in the case of the previously described embodiment, for which reason these parts of the hinge  2  will not be discussed again.  
         [0052]    The hinge arm  7  is also developed in the same way as in the case of the previously described embodiment. The only difference compared with the previously described embodiment is that the bedplate  5  has a base  48  in which the eccentric  49  is housed. The eccentric  49  projects into an oblong hole  62  in the intermediate piece  4 , its eccentric cam being accommodated in the oblong hole  62 .  
         [0053]    Through turning of the eccentric  49 , the intermediate piece  4  moves together with the hinge arm  7  in the direction of the height of the item of furniture.  
         [0054]    The development of the joint-adjustment screw  24  and its anchorage in the bedplate  5 , in the intermediate piece  4  and in the hinge arm  7  is the same as in the previously described embodiment.  
         [0055]    The depth adjustment of the hinge arm  7  takes place as in the case of the previously described embodiment by means of the eccentric  29 .  
         [0056]    In the embodiment according to FIGS. 17 and 18, the hinge arm  7  is housed on a further intermediate piece  40 . The hinge  2  thus has the following structure: bedplate  5 , intermediate piece  4 , further intermediate piece  40 , hinge arm  7  and hinge casing  6 . The housing of the hinge casing  6  at the hinge arm  7  as well as the closure mechanism are developed in the same way as in the case of the previously described embodiments.  
         [0057]    The bedplate  5  and the two intermediate pieces  4 ,  40  are preferably made from sheet steel.  
         [0058]    The bedplate  5  has a hole  15  through which a fixing screw  18  projects by means of which the bedplate  5  is secured to the furniture frame  1 .  
         [0059]    The intermediate piece  40  is designed L-shaped. A stirrup  42 , which extends in the longitudinal direction of the hinge arm  7 , is punched out from the bar  41 , resting against the front side of the frame  3 , of the intermediate piece  40 . The hinge arm  7  is pushed up onto this stirrup  42  and thus anchored to the intermediate piece  40 .  
         [0060]    The stirrup  42  is punched out from the intermediate piece  40  in such a way that it has laterally projecting edge projections  42 ′. The hinge arm  7  has a C-shaped region  7 ′ with inwardly directed projections  43 . When the hinge arm  7  is shifted onto the stirrup  42 , the projections  43  of the hinge arm  7  engage behind the edge projections  42 ′ of the stirrup  42 .  
         [0061]    The adjustment of the hinge arm  7  in the direction of the furniture door joint takes place by means of an eccentric  44  which is housed rotatable with a journal in a hole  45  of the stirrup  42 .  
         [0062]    The hinge arm  7  is again provided with an oblong hole  46  which is aligned transverse to the hinge arm  7 .  
         [0063]    The eccentric cam of the eccentric  44  is accommodated in the oblong hole  46  in mounting position.  
         [0064]    The eccentric  44  is riveted with its journal in the stirrup  42  and has a head which rests against the stirrup  42  outside. Through this design, the hinge arm  7  is held so that it cannot be lost at the intermediate piece  4 .  
         [0065]    The intermediate piece  40  again has a circular recess  47  in which a base  38  of the spiral disk  10  is accommodated. The spiral projection  36  of the spiral disk  10  lies against projections  37  of the intermediate piece  4 . Through turning of the spiral disk  10 , the intermediate piece  40  and thus the hinge arm  7  can be adjusted in the direction of the height of the item of furniture.  
         [0066]    The intermediate piece  40  is guided on one side by journals  39  which are developed at the bedplate  5  and which project into oblong holes  51  of the intermediate piece, and on the other by a connecting pin  52  which is housed in holes  54  of the bedplate  5  and projects through oblong holes  53  in the intermediate piece  40 .  
         [0067]    An eccentric  55 , the eccentric cam of which is accommodated in an oblong hole  56  of the intermediate piece  4 , is housed in the bedplate  5 .  
         [0068]    Through turning of the eccentric  55 , the intermediate piece  4  together with the intermediate piece  40  and the hinge arm  7  can be adjusted in the direction of the depth of the item of furniture. An oblong hole  57  in the intermediate piece  40  allows access of a screwdriver to the eccentric  55 .  
         [0069]    In the embodiment according to FIGS.  19  to  22 , the hinge  2  again has two intermediate pieces  4  and  40 .  
         [0070]    The bedplate  5 , the intermediate piece  4 , the intermediate piece  40  and the hinge arm  7  are articulated to each other by a pin  22 . The pin  22  projects through oblong holes  21  in the hinge arm  7 , slits  58 , open to the rear, in the intermediate piece  40 , circular holes  20  in the side bars  4 ′ of the intermediate piece  4  and circular holes  19  in the upwardly bent butts  17  of the bedplate  5 .  
         [0071]    The spiral disk  40  is accommodated with its cylindrical base  38  in a circular opening  47  of the intermediate piece  4 . Its spiral bar  36  (see FIG. 5) lies against projections  37  of the bedplate  5 . Through turning of the spiral disk  10 , the intermediate piece  4  together with the intermediate piece  40  and the hinge arm  7  is shifted in the direction of the height of the item of furniture.  
         [0072]    The adjustment of the hinge arm  7  in the direction of the depth of the item of furniture again takes place through an eccentric  29  which is housed in the intermediate piece  40 . The eccentric cam  30  of the eccentric  29  is accommodated in an oblong hole  31  of the hinge arm  7 .  
         [0073]    The joint-adjustment screw  24  is housed in a nut thread  59  of the intermediate piece  40  and is anchored with its head  26  in a stirrup  60  of the intermediate piece  4 .  
         [0074]    Through turning of the joint-adjustment screw  24 , the intermediate piece  40  together with the hinge arm  7  is tilted relative to the intermediate piece  4  and to the bedplate  5  about the axle formed by the pin  22 .  
         [0075]    In order that, during the joint adjustment, the position of the hinge axle is not changed in the direction of the depth of the item of furniture, the intermediate piece  4  has grooves  61 , running diagonally in its side bars  4 ′, in which journals  62  housed in side bars  40 ′ of the intermediate piece  40  engage. Because of the diagonal running of the grooves  61  and the journals  62 , upon turning of the adjustment screw  24  the intermediate piece  40  together with the hinge arm  7  is simultaneously shifted in the direction of the depth of the item of furniture, as a result of which the swivelling of the hinge axle during the joint adjustment is again balanced out.
