Abstract

In a mast flagpowder on ships with maintenance subject to additional elements such as lights, it is provided that the mast is pivotally mounted on a stationary base element. The pivoting movement is controlled by a screw jack with a threaded spindle feasible.

Description

The The invention relates to a device for masts on ships, in particular for rear flagpoles of mega yachts that lean over the Extend the stern of the ship and additional elements, such as floodlights, Anchor light and the like, have.

It has been shown to flagpoles of this kind for Maintenance and repair of additional elements accordingly have to be climbed to carry out appropriate work. It is customary for this, sprouts to arrange for climbing. Megayachts lack of these Additional elements as disturbing be felt.

The The object of the invention is in embodiments of this type with relative great Weight of the mast to provide a maintenance-free folding mechanism, which ensures a controlled laying of the mast in a simple way and an impairment the optics avoids.

The solution This object is achieved according to the invention in that a stationary Basic element over a pivot bearing receives the pivoting mast and the mast additionally with the primitive over a threaded spindle is adjustably coupled, which over a Screw jack in the mast is driven, with a bearing axis the threaded spindle engages the base element at a distance from the pivot bearing.

hereby a simple arrangement with a long service life is created, which enables safe operation without operator error.

A simple operation is created by the fact that the screw jack via a from the outside attachable crank operated is.

Around to create a fuse of an end position with optical cover, It is suggested that the in an inclined position arranged mast opposite to the pivot direction an extended Has area corresponding to the functional position of the mast Assigned to areas of the primitive.

Further It is suggested that the Mast on both sides of a surface flush arranged Bearing of the Spindelhubgetriebes, the one-sided Socket for crank holder has.

Farther is to protected Arrangement provided that the Screw spindle of the Spindelhubgetriebes in an associated bellows and protective tube is arranged.

In the drawing is an embodiment of Invention shown schematically.

It demonstrate:

1 a side view of a flagpole in the functional position;

2 an enlarged partial representation of a flagpole as a schematic representation;

3 a representation of the flagpole in different pivoted angular positions

The arrangement consists of one fixed on the deck 1 of the ship arranged basic element 2 that has a pivoting mast 3 receives. The mast 3 is arranged in an inclined position in this training and goes beyond the stern of the ship.

The mast 3 is with the primitive 2 over a pivot bearing 4 connected. In addition, there is a threaded spindle 5 arranged, the formation of a lever arm at a distance from the pivot bearing 4 at the basic element 2 via a pivot axis 6 is arranged. In the basic element 2 is a closure 14 arranged to solve in case of defects, the pivot bearing axis, so that in case of a defective Spindelhubgetriebe 7 accessibility is made possible. The threaded spindle 5 is in the swiveling mast 3 via a screw jack 7 guided, adjustable in the mast 3 over bearing washers 8th is stored torque-free, to ensure a slender mast cross-section, the bearing washers 8th finish flush with the outside of the mast.

The screw jack 7 has in this training an outwardly guided socket 9 , in which an attachable crank can be used, via which an adjustment of the recorded threaded spindle 5 via the screw jack 7 he follows. This is the mast 3 according to the pivot bearing 4 controlled pivoting, as in 3 is shown.

The mast 3 has on the outer side of a non-illustrated radiator and a camera and at the top of an anchor light 10 , where also in the basic element 2 a lamp 11 is arranged.

The swiveling mast 3 has opposite to the pivoting direction an extended range 12 in the erected functional position of the mast 3 corresponding areas of the basic element 2 is assigned and serves for securing and covering.

Furthermore, it is envisaged that the protected th arrangement of the threaded spindle 5 a bellows 13 and a protective tube 15 are arranged.

Claims (5)

Device for masts on ships, in particular for rear-flag masts of mega-yachts, which extend in an inclined position over the stern of the ship and additional elements, such as floodlights, anchor light and the like, have, characterized in that a stationary base element ( 2 ) via a pivot bearing ( 6 ) the pivotable mast ( 3 ) and the mast ( 3 ) additionally with the basic element ( 2 ) via a threaded spindle ( 5 ) is adjustably coupled, which is driven by a Spindelhubgetriebe in the mast, wherein a bearing axis of the threaded spindle engages the base member at a distance from the pivot bearing. Apparatus according to claim 1, characterized in that the screw jack ( 7 ) can be actuated via a crank attachable from the outside.
