Abstract
A rescue signalling device includes a waterproof buoyant body having a front end and a rear end and a compartment for accommodating a battery to provide a center of gravity for the body to float in water in a substantially upright neutral position with the front end pointing upwards. The device includes a first light source within the front end for energization by the battery to generate a light rescue signal, and a movement sensitive electrical switch for intermittently turning on and off the light source in response to the body being moved by water, back-and-forth, about the neutral position. The device is a lantern incorporating a second light source for lantern light operation.
Claims20
A rescue signalling device comprising
- a waterproof buoyant body having a front end and a rear end, including a compartment for accommodating a battery to provide a centre of gravity for the body to float in water in a substantially upright neutral position with the front end pointing upwards,
- a first light source within the body front end for energization by the battery to generate a light rescue signal,
- a movement sensitive electrical switch for intermittently turning on and off the first light source in response to the body being moved back-and-forth about the neutral position, and
- a second light source for a lighting operation as a lantern.
A combination lantern and signalling device comprising:
- a waterproof buoyant body having a front end and a rear end, including a compartment for accommodating a battery to provide a centre of gravity for the body to float in water in a substantially upright neutral position with the front end pointing upwards,
- a first light source within the front end of the body for energization by the battery for generating a light signal,
- a movement sensitive electrical switch for intermittently connecting the first light source to the battery in response to back-and-forth movement of the body about the neutral position,
- a second light source within the body front end for energization by the battery to generate a continuous lantern light, and
- an on-off electrical switch for connecting the battery to the second light source to produce the continuous lantern light whereby the first and second light sources are independently connected to the battery.
