Definitions

  • the present invention relates to a safety system for motor boats, preferably smaller motor boats, at which the motor boat engine cooperates with an ignition system.
  • None of the prior art safety systems provides double safety by simple means nor a way to choose one of several systems at a time.
  • the object of the present invention has therefore been to remedy said shortages by simple means and this is accomplished by providing the safety system with the characterizing features of primarily subsequent claim 1.
  • the safety system is provided with said characterizing features, double safety can be obtained if desired and one of several safety systems can be used if desired.
  • double safety can be obtained if desired and one of several safety systems can be used if desired.
  • the safety system 1 illustrated in the drawings is adapted for use in motor boats 2, preferably smaller motor boats, for breaking the operation of the motor boat engine 3 if the driver 4 falls overboard.
  • the safety system 1 cooperates with the ignition system 5 of the motor boat engine 3, said ignition system 5 being brought to break the operation of the motor boat engine 3.
  • the safety system 1 comprises a first safety device 6 and a second safety device 7.
  • the first safety device 6 is provided to establish, in activated condition, a physical connection between the driver 4 of the motor boat 2 and the ignition system 5 and this connection is broken or interrupted if the driver 4 falls overboard, whereby the ignition system 5 is brought to break the operation of the motor boat engine 3.
  • the second safety device 7 is provided to cooperate, in activated condition and through wireless communication between the driver 4 and the ignition system 5, with said ignition system 5 for bringing it to break the operation of the motor boat engine 3 if the driver 4 falls overboard.
  • the second safety device 7 is provided to be activated irrespective of whether the first safety device 6 is activated or not.
  • the driver 4 is able to use the safety system 1 in the following manner:
  • the second safety device 7 can preferably be mounted as an additional safety device in motor boats 2 which are already equipped with the first safety device 6.
  • the first safety device 6 is preferably of "dead man's handle"-type and comprises a first safety contact 9 mounted in the ignition system 5, a coupling member 10 which can be inserted manually in a recess therefor in the motor boat 2 such that said coupling member can cooperate with the first safety contact 9, a member 11 carried by the driver 4, e.g. a bracelet, and a connecting means 12, e.g. a string, which connects the coupling member 10 and the portable member 11 to each other.
  • a connecting means 12 e.g. a string
  • This first safety device 6 provides a physical connection between the driver 4 and the ignition system 5 and the length of the connecting means 12 is chosen such that the driver 4 can move freely in and at the driver's stand 8, but if the driver 4 falls overboard he or she brings the connecting means 12 with him or her such that the coupling member 10 is pulled out of its cooperation with the first safety contact 9, which in turn affects the ignition system 5 to break the operation of the motor boat engine 3 such that the motor boat 2 stops.
  • the second safety device 7 preferably comprises a second safety contact 13 which is mounted in the ignition system 5 and a control unit 14 which can cooperate with the second safety contact 13 for activation thereof such that it brings the ignition system 5 to break the operation of the motor boat engine 3.
  • the second safety device 7 further comprises a unit 15 carried by the driver 4 of the boat and which can be fastened to the driver by e.g. being provided on a tape or strip 16 which the driver can thread onto the leg.
  • the control unit 14 and the portable unit 15 carried by the driver 4 cooperate wirelessly with each other such that the control unit 14 is activated to cooperate with the second safety contact 13, which in turn cooperates with the ignition system 5 in order to bring said system to break or interrupt the operation of the motor boat engine 3 if the driver 4 falls overboard.
  • the portable unit 15 is a signal sender, e.g. a radio signal sender
  • the control unit 14 is a signal receiver, e.g. a radio signal receiver.
  • the signal receiver When the signals from the signal sender are broken or interrupted by water in which the driver 4 lands if he or she falls overboard, the signal receiver is activated, which in turn activates the second safety contact 13 such that it brings the ignition system 5 to break the operation of the motor boat engine 3.
  • the signal receiver may eventually also be activated when the driver 4 moves too far away from the signal sender.
  • a useful device for wireless communication is a device where the portable unit 15 is a unit which can be sensed, by the control unit 14, which here is a sensor unit, in case the portable unit 15 passes the sensor unit 14.
  • Said sensor unit may in such case be a logo extending around the motor boat 2 or parts thereof.
  • the first and second safety contacts 9, 13 can be mounted in a part of the ignition system 5 between an ignition lock 17 forming part thereof and the motor boat engine 3, and said first and second safety contacts 9, 13 can cooperate with the ignition system 5 such that they together or separately can affect said ignition system to break the operation of the motor boat engine 3.
  • Figs. 2-17 illustrate different ways to provide the first and second safety contacts 9, 13 of the first and second safety devices 6, 7 in order to obtain various functions.
  • figs. 2-5 the first and second safety contacts 9, 13 are illustrated having disconnecting functions, whereby fig. 2 shows said safety contacts in closing positions, meaning that the ignition system 5 is closed and the motor boat engine 3 can be started and in operation.
  • a restart device 18 is provided for restarting the motor boat engine 3, e.g. for rescuing the driver 4 when he or she has fallen overboard and the second safety contact 13 has been disconnected.
  • the restart device 18 preferably includes a by-pass 19 with a manually controlled contact 20 which is normally open (broken line) and which is closed (solid line) for reclosing the ignition system 5.
  • Figs. 6 and 7 illustrate the first and second safety contacts 9, 13 with connecting or closing functions and in fig. 6 it is shown as an example that the first safety contact 9 is closed and the second safety contact 13 open, whereby the motor boat engine 3 can be started and operative.
  • Fig. 7 illustrates as an example that if the driver 4 falls overboard and the second safety contact 13 has closed, the engine 3 is brought to stop.
  • Fig. 8 illustrates as an example that if one after the situation according to fig. 7 activates the first safety contact 9, the ignition system 5 is disconnected thereby, whereby the motor boat engine 3 can be started and operated.
  • Fig. 9 illustrates as an example that if the driver 4 falls overboard and the first safety contact 9 thereby is closed, the motor boat engine 3 is brought to stop.
  • Figs. 10-17 illustrate embodiments where the first and second safety contacts 9, 13 are connected in parallel relative to each other in the ignition system 5.
  • the first and second safety contacts 9, 13 have disconnecting functions.
  • Fig. 10 illustrates that if the first safety contact 9 is disconnected or open and the second safety contact 13 closed, the motor boat engine 3 can be started and operated.
  • Fig. 11 shows that if the second safety contact 13 is disconnected because the driver 4 has fallen overboard, the motor boat engine 3 is brought to stop.
  • first and second safety contacts 9, 13 have connecting or closing functions for breaking the operation of the motor boat engine 3.
  • a disconnecting device 21 is shown, permitting manual disconnection of the second safety contact 13 for restarting the motor boat engine 3 for e.g. being able to rescue a driver 4 when he or she has fallen overboard.
  • the motor boat engine 3 can be operated when the second safety contact 13 has been disconnected or opened by means of the disconnecting device 21, and as is apparent from fig. 17, the operation of the engine 3 can be stopped if the driver 4 falls overboard and the first safety contact 9 is closed.
  • the safety system 1 described above is primarily intended to be an inexpensive and efficient safety system for smaller boats which can be used also if only the driver 4 is on board.
  • Said ignition system 5 can be an electric or magnetic ignition system.
  • the safety system 1 is not limited to the embodiments described above and illustrated in the drawings, but may vary within the scope of subsequent claims.
  • the safety devices 6, 7 can be designed in other ways with regard to their construction and function.
