FR2814141A1 - Anchor or marker buoy has line on spring-loaded inner spool - Google Patents

Abstract

The buoy (1), e.g. a plastic sphere of 25 cm diameter, contains a line (2) on a spring-loaded spool (3), with a snap hook (6) on the free end of the line for attaching to an anchor or other underwater object. The spring (8) is tensioned as the line is paid out and causes the spool to retract it automatically when released. A handle (7) on top of the buoy is big enough to pass one or more fingers through.

Description

<Desc / Clms Page number 1>

 The present invention relates to a device for signaling submerged objects, preferably the anchors of pleasure boats.

 The technique used until today is that of orin. It consists in hanging its anchor with a fixed length rope, the latter being brought to the surface, attached to a buoy. The buoy is never located directly above the anchor because the fixed length of the rope is never the right one: too long, the buoy moves away, too short, the buoy sinks. This bulky, ill-suited system is therefore very little used.

 The device according to the invention makes it possible to always have the buoy perfectly above the anchor while keeping the rope under tension. The other ships can then place their anchor with great precision without risking crossing the chains of others.

 The system according to the invention consists of a buoy in which an automatic rope reel-unwinder is installed.

 The plastic buoy (1) must be of sufficient size to allow the desired length of rope (2) to be wound on the reel (3), which is also made of plastic. The coil rotates on a horizontal axis (4) fixed across the buoy. The rope comes out of the buoy in its lower part through an opening (5) with a diameter ten percent greater than the diameter of the rope used. By way of nonlimiting example, in the case of a spherical buoy, this will have a diameter of 25 centimeters and the rope, a length of 10 meters and a diameter of 8 millimeters. The rope will be

 equipped with a carabiner (6) to attach to the anchor. The buoy is equipped with a handle (7) on its top allowing at least one finger to pass.

 The rope unwinds as the anchor sinks into the water, the float remaining on the surface. This operation of unwinding the rope allows the compression of the spring (8) by winding. The carabiner will prevent the rope from entering the buoy.

 When the anchor is raised, the spring will relax and the rope will be wound on the spool. The length of the rope will adapt to all heights of water and all tides.

 The advantages of the invention are multiple: - small footprint, - ease of use, - possibility of leaving the system fixed on the anchor permanently.

 The buoy may be equipped with lighting to be visible at night and / or with a mast with a flag in the name of the ship.

 The device is particularly intended for boaters but can be applied without limitation in the following cases: - marking a bathing area, a channel.

 - identification of traps or nets for fishing - protection by signaling of a group of divers.

 The use of automatic orin is not

therefore not limited to boating, but can adapt to all activities related to the sea.

Claims (2)

Claims.  1) Device for signaling the presence of a ship's anchor and all submerged bodies or for marking out an area on the water, characterized in that it includes a buoy (1) (float) in which a rope (2) is wound on a reel (3) which tends to swallow the rope under the action of a spring (8) placed on the axis (4) of rotation of the reel.  2) Device according to claim 1 characterized in that a spring (8) is tensioned when the rope (2) is unwound from the spool.
