BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The invention relates to a fastening device for the fastening of a plurality of furniture fittings to a furniture part and including an anchoring rail which is to be fastened to a side wall of a piece of furniture and has openings for receiving fastening pins of the fittings. 
     2. Description of the Prior Art 
     According to the current state of the art, the individual furniture fittings of a cabinet are fastened individually by means of pegs or the like. Examples of these are base plates of hinges, furniture connectors, shelf holders and the like. It is also known to connect side walls of a cabinet to a top and a bottom thereof by means of special connecting fittings. 
     The object of the invention is to provide a fastening device by means of which the assembly of a piece or article or furniture can be considerably sped up. In this regard, the furniture fittings, for example base plates of hinges, are not to be fixed individually by tightening pegs or screws, but rather it is to be possible to position all the fittings, arranged one above the other in the finished cabinet, on one side on the wall of the piece or furniture, onto a base body of the fastening device and subsequently to fix all the furniture fittings in a single operation. 
     From AT patent 352 326 it is known to fix furniture fittings by means of a rail which is inserted into a groove in the wall of the piece of furniture. However, the fittings are fastened individually, it being necessary, in the case of the base plate of a hinge for example, to actuate two spreading or locking elements. 
     U.S. Pat. No. 4,671,481 describes a fitting for fastening a work surface to a wall of a piece of furniture, it being possible to hang a fitting part provided with hooks onto a rail which can be fastened to the wall of the piece of furniture having a plurality of slots. GB 14 34 130 A discloses the anchoring of side walls of a piece of furniture to supports by means of a strip-shaped fitting having projections which are insertable into slots of a post constructed on the side wall of the piece of furniture. In both cases, the projections of one fitting are inserted into the slotted rail or post and anchored by a relative displacement, which means that during assembly the two furniture parts and the fitting part have to be offset relative to one another. In this case, such fittings can only be used with great difficulty, if at all, when a plurality of parts are to be connected to one another by means of these fittings, possibly in different operations. 
     SUMMARY OF THE INVENTION 
     The object according to the invention is achieved by provision of at least one locking rail which is complementary to an anchoring rail and is displaceable relative to the anchoring rail and which has edge portions which latch in behind projections of fastening pins in a locking position. 
     Advantageously the locking rail is guided within the anchoring rail. 
     Advantageously, there is provision for the locking rail to be displaceable in the longitudinal direction of the anchoring rail and for both rails to be of approximately equal length. The displacement of the locking rail is effected advantageously by an eccentric mounted in the anchoring rail. 
     Advantageously, the locking rail is provided with keyhole-shaped holes. 
     When the fittings are positioned on the anchoring rail, their fastening pins project through larger regions of the keyhole-shaped holes of the locking rail. When the locking rail is displaced relative to the anchoring rail by a single rotation of the eccentric, the fastening pins are received in narrower parts of the keyhole-shaped holes and fixed by edge portions of the anchoring rail. Thus, all the fittings of one row of a side wail of the piece of furniture are fixed by a single rotation of the eccentric. It is possible here to fix base plates of hinges, furniture connectors connecting the side wall to the top and bottom, as well as shelf holders and the like.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     The piece of box-type furniture shown in FIG. 1 has side walls  1  which are connected by means of fastening devices according to the invention to the bottom  2 , crossmembers  5 , a rear wall  22  and, by way of hinges  6 , to the door  3  of the piece of furniture. 
     The side walls  1  have vertical grooves  16  on the inside (FIG.  3 ), at the front and rear, in which anchoring rails  4 ,  10  of the fastening devices are received. Each fastening device has an anchoring rail  4  with a U profile, and a flat locking rail  10  which is guided in the profile of the anchoring rail  4 . 
     The anchoring rail  4  is provided at its lateral webs with inwardly directed indentations  15  which form a guide for the locking rail  10 . 
     Furthermore, the anchoring rail  4  has first holes  30  which permit the passage of fastening pins  13 ,  14 ,  17 . 
     The locking rail  10  is provided with corresponding second holes  29  which are designed in the shape of keyholes. The fastening pins  13 , which are arranged on the crossmembers  5 , supporting rails  7  of a drawer guide assembly or base plates  9  of the hinges  6 , are pushed through the holes  30  and the wider regions of the keyhole-shaped holes  29 , as are the fastening pins  17  of shelf support  8  or the fastening pins  14 , the latter being constructed as furniture connectors and being screwed or pegged into the bottom  2 . When all the fittings are mounted, the locking rail  10  is displaced vertically relative to the anchoring rail  4  by means of eccentric  12  which is received in a hole  23  of the anchoring rail  4  and projects into a horizontally elongated hole  26  of the locking rail  10 . As a result, the fastening pins  13 ,  14 ,  17  are moved into the narrower region of the keyhole-shaped holes  29 , the edge regions of the holes  29  or of the locking rail  10  latching respectively into grooves  31  and undercuts  32 ,  33  of the fastening pins  13 ,  14 ,  17 . 
     All the members  7 ,  8 ,  9 , as well as the crossmembers  5  and the bottom  2 , are thus locked to the rails  4 ,  10  by a single operation. 
     In the exemplary embodiment shown, the grooves  31  on the fastening pins  13  are arranged laterally and undercut  32  of the fastening pin  14  is an annular groove. The fastening pin  17  is of hammer-shaped construction, the locking rail  10  latching by the edge of a keyhole-shaped hole  29  into the undercut  33  which is delimited by the head and the neck of the fastening pin  17 . 
     In the exemplary embodiment, there are additionally provided leaf springs  11  which are fastened to the locking rail  10 . The leaf springs  11  can be fastened to the locking rail  10  at a plurality of locations along the length of the locking rail  10 . As shown in FIGS. 3 and 9, the leaf springs  11  are riveted to the locking rail  10  and engage on the head of the fastening pin  14 , with the result that the fastening pin  14  is drawn into the profile of the anchoring rail  4  and the side wall  1  is pressed against the bottom  2 . 
     In the exemplary embodiment according to FIGS. 10 to  12 , anchoring rails  18  are designed with box-shaped profiles of rectangular cross section. Each anchoring rail  18  has a laterally protruding web  34  which projects into a complementary groove on the end face of the side wall  1  of the piece of furniture. In this way, the anchoring rail  18  is anchored to the side wall  1 . The web  34  may preferably have a fir-cone profile to create a better hold in the groove of the side wall  1  of the piece of furniture. The side wall  1  of the piece of furniture is preferably produced from a wood-based material, for example as a particle board. 
     In contrast to the previously described exemplary embodiment, in which the fastening devices are set into the side wall  1  of the piece of furniture, the anchoring rails  18  in the exemplary embodiment according to FIGS. 10 to  12  are joined onto the side wall  1  of the piece of furniture and therefore increase the depth of the entire side wall of the piece of box-type furniture. 
     The front anchoring rail  18  has at its side directed toward the door  3  a damping profile of configuration  20  made of plastic or rubber, against which the door  3  rests in the closed state. 
     The locking rail  10  is designed in the same way as in the previously described exemplary embodiment and is again actuated by way of an eccentric  12  which is received in a hole  23  of the anchoring rail  18 . Likewise, the fastening pins  13 ,  14 ,  17  of the respective of the fittings and crossmembers  5  or the bottom  2  are of the same design, so that both systems (anchoring rail  4  or anchoring rail  18 ) can be easily exchanged at any time. 
     In the exemplary embodiment according to FIGS. 14 to  16 , anchoring rails  24  are again designed with a rectangular box-shaped profile. 
     In the exemplary embodiment shown, the anchoring rails  24  together with horizontal transverse profiles  25 ,  27  form a framework. However, they could also have lateral webs  34 , as in the previously described exemplary embodiment, or other anchoring means, in order to be connected to a side wall  1  of a piece of furniture. 
     Two locking rails  19  are inserted into the anchoring rails  24 . The locking rails  19  each have a C-shaped profile, the lateral webs being directed toward each other. This means that the central webs of the locking rails  19 , in which the keyhole-snaped holes  29  are formed, rest against the broader webs of the anchoring rails  24  having the holes  30  for the fastening pins  13 ,  14 ,  17 . 
     It is thus possible to fasten both fittings  7 ,  9  and crossmembers  25 ,  27  to two sides of the anchoring rails  24 , so that these anchoring rails  24  are particularly suitable for the construction of partitions. 
     The vertical displacement of the anchoring rail  19  is again effected by way of the eccentric  12 , there being provided in each anchoring rail  24  two eccentrics  12  at two mutually opposite sides. 
     The C-shaped locking rails  19  are again provided with leaf springs  11  (advantageously the leaf springs  11  are riveted to the locking rails  19 ) which press on the heads of the fastening pins  14  for the crossmembers  25  and thus draw the crossmembers  25  and the anchoring rails  24  together. It is thereby ensured that, upon actuation of the eccentrics  12 , the locking rails  19  in each case latch into the annular grooves  32  of the fastening pins  14 . 
     Just as all the fittings  7 ,  6 ,  9  or connecting parts are locked by a single rotation of the eccentric  12 , they are also released simultaneously by a rotation of the eccentric  12  in the opposite direction, so that it is very easy to exchange fittings and the like.
