FLOATABLE DIVING TORCH
BACKGROUND OF THE INVENTION
1. Fields of the invention
The present invention relates to a diving torch floating on the water,
especially to a diving torch that floats on the water surface without
sinking to the bottom while being dropped into the water. Thus people
working on the water can pick up the diving torch quickly and
conveniently once the diving torch fell into the water. Moreover, people
in the water and in distress can use the torch asking for help. Thus the
practical effects of the diving torch floating on the water are increased.
2. Descriptions of Related Art
A common electric torch available now consists of a main body, a
light shade holder and a bottom cover. At least one light emitting part is
mounted in a top of the main body and at least one battery provides
power to the light emitting part. A switch member is for turning on or off
the light emitting part. The battery is disposed in the main body and is
limited by fastening of the bottom cover while the light shade holder is
covered over the light emitting part and is threaded onto a top of the
main body. Thereby an electric torch for lighting purposes is formed.

However, various kinds of electric torches available now can only
provide lighting in use and have following shortcomings:
1. This type of electric torch has no waterproof design so that in use,
circuitry and current-conducting strips inside the electric torch are easy
to have rust stains due to moisture and dampness infiltrating into the
electric torch so that the electric torch is damaged and out of order.
2. The electric torch is not only without waterproof design, but also
unable to float. Thus once the electric torch is dropped into the water, it
sinks to the bottom quickly. For people working on the water, the
electric torch is often dropped into the water and sinking into the bottom.
Thus the electric torch is lost or damaged and this causes a great loss.
3. The electric torch generally includes a switch for turning on/off the
electric torch disposed on a lateral side of a main body. Or the on/off is
controlled by adjusting the degree of thread tightness of the main body
with the light shade holder/or the bottom cover. However, electric
torches with such design are unable to resists water and withstand water
pressure so that they can't be use in the water.
SUMMARY OF THE INVENTION
Therefore it is a primary object of the present invention to provide a
floatable diving torch that floats on the water surface without sinking to
the bottom once the diving torch is dropped into the water. For people

barrel 3. The switch set 4 and the back cover 5 are connected with and
located to each other by the threading and assembling of the threaded
portions 413, 452 respectively of the controller 41 and of the press
member locating sleeve 45 with the switch set's threaded portion 52.
Then the barrel's threaded portion 51 on the inner surface of the upper
part of the back cover 5 is threaded and connected with the threaded
portion 37 on the outer surface of the bottom end of the barrel 3.
In use, the present invention prevents moisture ingress and provides
waterproof protection by the waterproof washer 35 between the barrel 3
and the front cover 1, the water proof washer 38 between the barrel 3 and
the back cover 5, and the waterproof washer 46 between the through hole
53 of the back cover 5 and the switch set 4. Once the diving torch is
dropped into the water, it floats without sinking into the bottom due to
CA 02691419 2010-01-25

the waterproof protection and air filled in the receiving space 31 on the
front end of the barrel 3.
Furthermore, the switch set 4 is mounted in the back cover 5 and the
waterproof washer 46 is disposed in the through hole of the back cover 5
correspondingly so that moisture will not enter through the through hole
53 of the back cover 5. Moreover, in the switch set 4, the control switch
412 of the controller 41 is pressed by the press member 44 and is
protected by the press member locating sleeve 45 so that the controller
41 of the switch set 4 can withstand a high pressure.
In summary, the present invention has following advantages
compared with the structure of the diving torch available now:
1. Due to waterproof washers respectively arranged between the barrel
and the front cover, between the barrel and the back cover, and between
the through hole of the back cover and the switch set, moisture will not
enter the diving torch. Thus the diving torch is waterproof and is not
easy to have rust stains or get damaged caused by moisture ingress.
2. The present invention prevents moisture ingress and provides
waterproof protection by the waterproof washers arranged between the
barrel and the front cover/the back cover, and between the through hole
of the back cover and the switch set. Moreover, the front end of the
barrel is extended outward to form a receiving space that is full of air.

Thus the diving torch can still float over the water without sinking into
the bottom once it is dropped into the water. Thus not only people
working on the water can pick up the dropped diving torch quickly,
people in the water and in distress can also use the diving torch asking
for help.
3. The switch set of the present invention can withstand a high
pressure and will not get damaged deep down under the sea. Thus divers
can carry the diving torch with them while working under the water.
Once they are in danger or trying to ask for help, the diving torch is
blinking as a signal for help. By a rope connected the diving torch with
the diver, the diving torch is released and is allowed to float on the water
by the air in the receiving space of the barrel. Once the signal for help is
received by people working over the water, they can rescue and help
those in distress immediately and the rescue time is dramatically reduced,
as shown in the schematic drawing of Fig. 4.
Additional advantages and modifications will readily occur to those
skilled in the art. Therefore, the invention in its broader aspects is not
limited to the specific details, and representative devices shown and
described herein. Accordingly, various modifications may be made
without departing from the spirit or scope of the general inventive
concept as defined by the appended claims and their equivalents.
