manoeuvring of a caisson by pivoting

Said pivot axes are created by four support members (3, 4, 5, 6) for the control lever (1) in the operating console, in pairs defining each one of the pivot axes for the control lever.

A door is hingedly secured to one upright.

The hinge defines a pivot axis for pivoting the door.

The door, in its locked position, is locked relative to the housing, and the door, in its unlocked position, is pivotable about the pivot axis.

The maneuvering arrangement (20) is used to maneuver vertical movement of a door, among other things.

In accordance with the invention a device in door arrangements is provided comprising a plurality of door panels (12) which by hinge means are hingedly interconnected in sequence to pivot about pivot axes.

When the door (5) pivots in a first pivoting direction, the control mechanism (38) pivots the door handle (17) in a second pivoting direction counter to the first pivoting direction.

Two jacks (7) allow the handling of the door.

A rotatable structure supports (16) the rotary distribution means and a stationary support (18) rotatably supports the rotatable structure.

A potentiometer (27) is connected to the hinge pin (7) for maneuvering of a remote member, complementarily to or by substitution of the cable.

The pivotal manipulation of the door engages the latch of the central latch bracket to the pin, to secure the door to the doorframe.
