  • holes 66 are provided in the wall of the base plate 6 .
  • the lever 64 has a base 641, followed by locking 642 on two sides.
  • the latches 642 have an L-shaped cross-section, wherein the horizontal leg is arranged on the side facing away from the base plate 6. In the idle state, the latches 642 are arranged in sections below the holding blocks 622.
  • To the locks 642 follow bolt-shaped portions 643 having at their ends perpendicularly oriented guide rods 644. Through the longitudinal center line of the bolt-shaped portions 643, the tilt axis of the lever 64 extends.
  • a linkage 10 is provided as a mechanism for locking and unlocking the device instead of the lever 64 on the base plate 6.
  • the linkage 10 has two push rods 101, which protrude beyond the base plate 6.
  • the pushrods 101 are guided on their sides remote from the base plate 6 in tunnel-like projections 102, which are provided on mounting plates 103.
  • the mounting plates 103 are bolted to the table top 1 '.
  • the push rods 101 are articulated to an actuating rod 104, which is mounted in tube-shaped receptacles 105, which are connected to the mounting plates 103.
  • the receptacles 105 are movable relative to the mounting plates 103.
  • About the linkage 10 is a synchronization of the two devices 5 on the table top 1 '.
  • the table leg receptacle 7 has a square shape. It is provided on its one side with webs 71, which are provided at their free ends with holes. In the assembled state, the webs 71 are arranged offset to the webs 63 of the base plate 6. The holes provided in the webs 63 and 71 are aligned in the assembled state. In the assembled state, the holes take on a hinge pin 8 which is mounted in the bores 66 of the base plate 6. The holes 66 then form the hinge bearing of the device.
  • Adjacent to the webs 71 7 holes 72 are arranged in the table leg recording, which are provided for the rotatable mounting of guide arms 73.
  • the guide arms 73 have at their one end a sleeve 731 which is arranged at right angles to the guide arm 73 and which is received in the mounted state by the bore 72.
  • a round guide stump 732 is provided, which is also at right angles to the guide arm 731 is aligned and in the assembled state in the guides 621 of the recess 62, the base plate 6 is guided.
  • L-shaped locking hooks 74 are arranged on the table leg receptacle 7 in cross section. Due to their L-shaped design, the locking hooks 74 are provided at their base plate 6 end facing with projections 741.
  • the projections 741 have run-on slopes 742 at their free ends.
  • the table leg holder 7 On its side facing away from the base plate 6, the table leg holder 7 is equipped with a circular recess 75 in the exemplary embodiment.
  • the recess 75 receives a receiving ring 76 in the assembled state, the outer diameter of the clear width of the recess 75 corresponds;
  • the inner diameter of the receiving ring 76 corresponds to the clear width of the table legs 2.
  • the receiving ring 76 may have different inner diameter with the same outer diameter, whereby an adaptation to table legs of different diameters is possible.
  • the receiving ring 76 has on one side a radially oriented, rectangular cut 761, which corresponds in the assembled state with a sliding block 9 and secures the ring 76 against rotation.
  • the table leg receptacle 7 On the side facing away from the webs 71, the table leg receptacle 7 is provided with a plug 77 made of rubber, which is held clamped in an opening 78. The plug 77 serves as a buffer when folding the tables to avoid damage.
  • the sliding block 9 has on its side facing the table leg 7 side in the exemplary embodiment, two pins 91 which - not shown - holes in the table holder 7 and with which the nut 9 is held in the table leg holder 7 under interference fit.
  • the unlocking of base plate 6 and table leg 7 is required.
  • the lever 64 or the linkage 10 is operated against the force of the spring 65.
  • the latches 642 arranged adjacent to the base 641 are moved in the direction away from the respective table leg 2.
  • the latches 642 thus release the projections 741 of the locking hooks 74, so that the table leg receptacle 7 is unlocked from the base plate 6.
  • the base plate 6 is pivotable about the axis of rotation of the hinge pin 8 through the longitudinal center line of the hinge pin 8 in this state. In the outermost position, provided on the guide arms 73 guide stumps 732 fall into the recess 62. This prevents accidental folding back of the table top 1, 1 ', since the free ends of the guide arms 73 with the guide stumps 732 at the bottom of the recess 62 and supported on the guide rods 644.
  • the table top 1, 1 'with base plate 6 in a simple manner in the direction of the table leg receptacle 7 around the hinge pin 8 is folded.
