Abstract

The invention relates to a mast laying device for sailboats for setting and laying a non-articulated mast (1) which is tiltable in a mast chair (2) about a pivot axis (3) arranged in a direction tiltable and fixable in a vertical position, by means of a Dirk (6 ) is connected to the lashed large tree (5) and at the mast base a pull rope (8) for placement and placement of the mast (1) is attached. It is characterized by the fact that the adjustable mast (1) including the mast chair (2) is rotatably mounted about its vertical axis of symmetry; that the Dirk (6) is kept in tension when placing and placing the mast (1); and that the traction device for placement and placement of the mast (1) does not hinder the vertical rotation of the mast chair (2).

Description

The The invention relates to a device for placement and placement of the mast a sailboat, even while driving through the water can be used.

From the GB 1 315 301 A is known a mast footrest for sailboats, which has a vertically arranged pivot which forms a vertical axis of symmetry about which the mast is rotatable. In addition, perpendicular to the pivot pin or a bolt that holds the mast either vertically or allows a flip towards the deck.

The US 7,137,346 B1 also discloses a mast laying device in the form of two sleeves which are pivotally connected together by a hinge. In order to allow the pivoting movement, one of the two sleeves is provided with a locking piece, which must be removed for pivoting to make room for the pivoting operation. The mast of a sailboat is pushed over the mast laying device or attached and rests in normal operation on the mast shoe of the sailboat. On the other hand, when the mast is to be placed on deck, it is first lifted to above the separation point of the two sleeves and fixed there by a pin. Thereafter, the locking piece is removed and the mast can then preferably be folded back.

In Sailing areas with bridges, overhead lines and others, the Headroom limiting obstacles, is It is of considerable advantage if the mast can be laid. The Laying and placing the mast without a crane is usually on boats limited to mast lengths up to about 12 meters in length. Very short masts can be set without assistance by the crew become. From a certain mast length but are technical Tools for setting and laying the mast indispensable. Best known the Jutt. It serves the angle between mast and Pull rope at the top of the mast to make so great that with handpicked forces of the mast and again can be set. In general, between the tow rope and a fixed point on board a pulley mounted. The problem, that occurs in all known devices, the lateral stabilization of the mast during laying or placement. With wave movements, which are generated in particular by passing ships and which lead to the taxi of the boat, the mast must be sideways be supported. If this does not happen, then step in the pivot bearing of the mast chair or mast so large torques on that destroys the pivot bearing or the mast bent in this area. This problem can be reduced be that the upper walls in the axial direction of the pivot bearing be fastened in the railing area. When setting and laying the mast The upper walls are easily loosened and then serve the lateral Stabilization.

One second problem is that the above described Devices usually not immediately during the Ride can be used. Because the known technical Solutions require technical devices that Damage to the mast or pivot bearing during roll movements of the boat while placing or laying the mast prevent. These are relatively expensive and can be used in usually not be used while the boat is sailing.

The The present invention solves these problems by: a unscheduled mast is driven and this when setting and laying is rotatable about a vertical axis. The problem of lateral stabilization is inventively achieved in that the Maststuhl is rotatably mounted about a vertical axis, the Dirk the lateral oscillations of the mast when laying limited and cushioned, the boom remains fixed and the rope, which is attached to the lower end of the folding mast and the actual Setting and laying serve, does not hinder the aforementioned oscillations. The rotatable about a vertical axis storage of the mast base and the mast, coupled with a strained Dirk, prevents the occurrence of large torques in the pivot bearing, during roll movement of the boat to damage the mast or Mastfußes can drive.

The Invention can be used with all sailboats equipped with tilting mast be used. It is particularly advantageous for Sailboats where the mast alone is cocked by the crew out while driving to drive through bridges should be placed.

The The invention will now be explained in more detail with reference to a drawing; show it:

1 an embodiment with a stationary mast;

2 the embodiment of 1 with the mast during laying.

In the 1 The arrangement shown consists of a folding mast 1 in a mastchair 2 stands and in this about a horizontal pivot axis 3 is pivotable. The mast chair 2 is on a lower mast 4 mounted and rotatable with this about the vertical axis. The lower mast 4 is from a warehouse 12 in the deck 11 and from an abutment 10 kept on the keel.

The folding mast 1 is in normal position vertically in the mast chair 2 and pivots when laying the mast around the pivot axis 3 , The mast chair 2 is locked in the sail position and then can not rotate around the vertical axis. A second lock prevents the folding mast tilts around the pivot axis. The mast is unsung.

The big tree 5 is at the mast chair 2 struck with a Lümmelbeschlag and is when setting and laying the mast in a mast pad 7 locked. The Dirk 6 from the mast-top to the nock of the boom is always kept stiff when placing and placing the mast.

The 2 shows the arrangement during the laying of the folding mast 1 , The locking of the mast chair 2 and those of the pivot bearing 3 are solved in this process. The folding mast is now through the rope 8th held that over a winch 9 is fished or densely fetched. When laying the folding mast becomes the rope 8th fisted and the Dirk 6 simultaneously closed. Due to the stiffness of the Dirk, the lateral movements of the folding mast are severely limited and cushioned during roll movements of the ship. Since the mast chair is rotatable about its vertical axis, no destructive torques arise in the pivot bearing with the slight lateral movements of the folding mast. The forces acting on the Dirk are dissipated via the stable mast support and the mainsheet on the hull.

Out the exemplary description of the operation of the mast laying device it can be seen that the mast while driving can be placed and put without the crew Must leave cockpit.
