FR2551020A1 - Device for auto-releasable buoy - Google Patents

Abstract

The invention relates to a device which makes it possible to release a buoy as soon as a person falls into the sea without manual intervention. It consists of a box 1 enclosing in the upper part the release mechanism and in the lower parts on one side the buoy 2 and on the opposite side the bobbin 15. Triggering of the release is carried out by the transmitter carried by the solitary navigator; upon contact with the water, the transmitter transmits a pulse to the receiver 3 which supplies the electromagnet 4 and frees the buoy 2. The contactor 22 connects into the circuit the visual 5 and acoustic 16 devices, stops the motor or interrupts the automatic control. Resetting the device is carried out by pulling the knob 7. To restart the motor in the presence of a crew, release can be brought about by pressing push-button 8. The device according to the invention is particularly intended to increase the chances of rescue of solitary sailors.

Description

DESCRIPTION
The present invention relates to a device for dropping a buoy without manual recourse, hence the title "Self-releasable buoy".

The dropping of a buoy is traditionally carried out by a person present on the boat other than the sinking, in the case of a solo navigator no help from the boat can reach him
The device according to the invention overcomes this drawback.

 It includes a chest containing the buoy connected by a rope with a length of 70 meters, a receiver and the release device controlled by an electromagnet, the solitary navigator being necessarily equipped with the transmitter which in contact with the water triggers the entire mechanism for dropping the buoy, as well as the audio and visual signaling.

Plate 3 represents the coil side view
Plate 4 represents the transmitter Full-scale
Plate 5 represents the positioning on the boat
Plate 6 represents the diagram of the receiver
Plate 7 represents the diagram of the transmitter
The device shown in Figure 1 comprises a chest (1) in marine plywood having the dimensions of 62 centimeters for the width, 61 centimeters for the height and 24.5 centimeters for the width.

In the upper part of the boot we have the whole release mechanism (6) the receiver (3) the electromagnet (-4) the contactor (22) the push button for manual release (8) the reset button (7) to outside the rotating beacon (5) on the outside wall the attachment device to the boat (9)
The lower part is divided in two, according to section AA in figure 2. On one side we have the buoy (2) provided with the reversing lamp (11) the whole being connected by the clip (12) to the mechanism.

In the opposite side we have the reel (15) with 70 meters of rope, the crank (14) for rewinding. For boats without batteries, it is possible to adapt a dry battery (13)

Different kinds of use 1 mbilrcation of veil
a) A man on board threshold
The solitary navigator must necessarily carry the transmitter on him figure 4. If he falls overboard in contact with batten the screws (20) put the circuit of the transmitter on which transmits a pulse to the receiver (3) which supplies the electromagnet (4) releases the buoy (2) via the contactor (22) the circuit of the sound devices (16) flashing light (5) starts and cuts the automatic pilot if necessary .

b) Two men on board
The coxswain must wear the transmitter figure 4
If the deckhand falls into the water, the coxswain has two possibilities of dropping the buoy by pressing on the push button t21) of the transmitter or on the push button (8) the buoy is released immediately. The visual and sound devices are put into operation, for restarting the coxswain must lift the button (7) to reset.

If the coxswain is on the night shift only the helm falls overboard while his teammate is sleeping while the alert system is activated the audible signal allows the crew to be alerted.

 In all cases, the buoy is fitted with a reversing lamp (11) for night tracking.

20) Motor boat
a) One man on board
Same process as for the sailing boat. In this case the device stops the engine.

b) Two men on board
MCame process as in the previous cases for restarting the engine, pull the button (7)
Advantage of this releasable buoy device: The buoy is dropped in a very short time it drifts in the same way as the shipwrecked according to the winds or currents at a very reduced distance from man to sea. It allows for a solitary navigator to increase his chances of survival.
