Table with pivotable table top
Presented is a table with a pivotable table top that is mounted rotatably and lockably about an axis of rotation extending in a longitudinal direction. The table has a pivoting mechanism on a table frame in the upper region of two lateral table legs. The table can be folded out or folded between a horizontal use position and a storage position. A pivoting movement of the table top is achieved, while combining secure operation and simple handling. The pivoting mechanism includes at least one pair of inter-engaging, mutually complementary tooth portions that are arranged concentrically about the axis of rotation. The tooth portions can be moved apart relative to one another by at least the tooth depth in the direction of the axis of rotation in order to enable the pivoting movement. In each pair, one tooth portion is mounted fixedly in terms of rotation with respect to the table leg and the other tooth portion is mounted fixedly in terms of rotation with respect to the table top.
