The invention presents a table system which has an axially oriented plug fastening means ( 3, 4 ) between table leg ( 2 ) and tabletop ( 1 ) and an automatic retaining device ( 5, 6, 7 ) which retains the table leg ( 2 ) after it is inserted into the tabletop ( 1 ). According to the invention, advantages such as a high degree of variability and particular convenience in terns of assembly are achieved.

The table system as claimed in  claim 1 , characterized in that the plug-type fastening ( 3 , 4 ) has an axially acting alignment bore ( 4 ) for receiving an alignment bolt ( 3 ), and in that a radially acting positioning element ( 8 ) defines the rotational direction of the table leg ( 2 ). 
   
   
       3 . The table system as claimed in  claim 2 , characterized in that the plug-type fastening ( 3 , 4 ) has at least one bore ( 4 ), which is conical at least in sections, and an upwardly tapering alignment bolt ( 3 ) which is in particular designed to be slim, round and conical at least in sections, with an overall cone angle of between 3 and 30 degrees, preferably approximately 20 degrees. 
   
   
       4 . The table system as claimed in  claim 2 , characterized in that the plug-type fastening ( 27 , 28 ) forms a cylindrical bore ( 27 ) and a bolt ( 28 ) with short spherical ( 28   a ) or short cylindrical sections ( 28   b ), which bolt ( 28 ) forms a neck ( 34 ) between said sections. 
   
   
       5 . The table system as claimed in  claim 1 , characterized in that the alignment bolt ( 3 ) of the plug-type fastening has an encircling channel ( 3   a ), depressions or bores, in particular two to four conical bores ( 40 ) which are designed for the form-fitting insertion of a latching device ( 5 , 6 , 7 ) or ejector device ( 23 , 24 ). 
   
   
       6 . The table system as claimed in  claim 1 , characterized in that the retaining device runs transversely with respect to the table leg, in that said retaining device has a round latching bolt ( 5 ), with a forwardly tapering, in particular self-locking conical insertion section ( 5   a ), and has a spring ( 6 ) for automatic insertion and a handle ( 7 ) for the release of the latching bolt ( 5 ) in the direction counter to the spring force. 
   
   
       7 . The table system as claimed in  claim 1 , characterized in that the retaining device has a tilting lever, having a spring for automatic insertion and a handle for the release of the tilting lever in the direction counter to the spring force, with the tilting lever having an insertion bevel which is in particular of self-locking design. 
   
   
       8 . The table system as claimed in  claim 1 , characterized in that the retaining device consists in that the plug-type fastening itself is of self-locking design, in particular in that said retaining device has a very slim conical bolt ( 22 ) with a corresponding conical bore ( 35 ), with an overall cone angle of between 2 and 25°, in combination with an ejector device ( 23 , 24 ). 
   
   
       9 . The table system as claimed in  claim 1 , characterized in that the ejector device ( 23 , 24 ) has a torsion bolt ( 23 ), which runs transversely with respect to the table leg, with an eccentric insertion section ( 23   a ), and a handle ( 24 ) which sets the torsion bolt ( 23 ) in rotation in order to eject the table leg. 
   
   
       10 . The table system as claimed in  claim 1 , characterized in that said table system has, on the table legs, in each case at least one positioning element ( 8 ) which is in particular spherical in sections, and in that the positioning element ( 8 ) is designed both for insertion into the alignment bore ( 4 ) and also for insertion into cutouts which align the table leg in the rotational direction, in particular into a plurality of grooves ( 9 ) which are arranged in a star shape with respect to the plug-type fastening. 
   
   
       11 . The table system as claimed in  claim 1 , characterized in that an axially acting alignment bore ( 4 ,  45 ), which is designed in particular as an insert sleeve, is situated directly at the corner of the table top, in that at least one radially defining cutout ( 9 , 46 ) is situated adjacent thereto, and in that two in particular identical alignment bolts ( 34 ), or else one alignment bolt ( 3 ) and one positioning bolt ( 8 ), are situated in each case on the table leg. 
   
   
       12 . The table system as claimed in  claim 1 , characterized in that the table top unit has the following design:
 a supporting panel ( 42 ) is provided,   a table frame which is formed in particular from hollow profiles ( 43 , 44 ) is provided,   the plug-type fastening ( 45 , 46 ) is situated in each case in the table frame, in particular in the longitudinal tube ( 43 ) thereof,   the retaining device ( 41 , 47 , 48 , 49 , 50 ) is situated in each case in the table frame, in particular in the transverse tube ( 44 ) thereof.   
   
   
       13 . The table system as claimed in  claim 1 , characterized in that the table leg has the following design in each case:
 a hollow profile ( 35 ) with an upper and lower cover ( 36 , 37 ) is provided,   the alignment bolt(s) ( 34 ) is/are fastened to the upper cover ( 36 ),   the alignment bolt(s) ( 34 ) is/are braced, together with the upper cover ( 36 ), with the lower cover ( 37 ) by means of one or more tension rods ( 38 ) which run in the hollow profile ( 35 ).
