ABSTRACT:
A device in a plane supported between columns by means of hooks cooperating with the columns in a locking position for adjusting and locking the plane in different positions along the columns. In known devices of this type shifting of the plane from one position to another is troublesome and time-consuming and, further, no change of the distance between the columns is permitted. In order to make this possible the hooks (2) are connected to the plane (5) by means of links (3) articulatedly connected with the plane and pivotally connected with each their link (3) in a hinge (8), said links being pivotable, one before the other, to withdraw the respective hook (2) from locking engagement with the column (1), by which displacement of the plane can take place in one direction as well as the other, a support means (8) being associated with each hook (2) and serving in locking position as a support for the hook against the respective column (1).
