Inflatable boat having self-inflation system
Disclosed is an inflatable boat having a self-inflation system which advantageously makes it possible to shorten the air injection time, thus quickly taking a proper measure under an emergency situation, in such a manner that a speed tube or an air passage tube disposed in the boat's body and an air distribution system each help inject compressed air into a plurality of compartments forming the boat's body simultaneously at a designated pressure.
1. An inflatable boat, comprising:
a tube shaped body part having a plurality of compartments in an interior of the tube shaped body part;
a speed tube installed at each of both lower sides of the tube shaped body part;
a keel installed on a longitudinal center axis at an outer side of the tube shaped body part;
a compressed air supply part which includes a compressed air supply source for generating or storing compressed air, thus supplying the compressed air to the speed tubes,
an air distributor which supplies air to each compartment of the tube shaped body part from the speed tubes; and
an air connection part which supplies air from the tubed shaped body part to the keel,
wherein air can be supplied to each compartment of the tube shaped body part and the keel from the compressed air supply part via the speed tubes, thus inflating the boat.
2. The inflatable boat according to claim 1 , wherein said air distributor comprises a plurality of first over pressure relief valves installed at each compartment to supple compressed air from the speed tubes to each compartment of the tube shaped body part.
3. The inflatable boat according to claim 1 , wherein said air connection part comprises a connection hose connected from the tube shaped body part to the keel for supplying air from the tube shaped body part to the keel.
4. An inflatable boat, comprising:
a tube shaped body part having a plurality of compartments in an interior of the tube shaped body part;
a keel installed on a longitudinal center axis at an outer side of the tube shaped body part;
an air passage tube which is embedded in a longitudinal direction in both inner sides of the tube shaped body part;
a compressed air supply part which includes a compressed air supply source for generating or storing compressed air, thus supplying the compressed air to the air passage tubes, respectively;
an air distributor which supplies air to each compartment of the tube shaped body part from the air passage tubes; and
an air connection part which supplies air from the tube shaped body part to the keel,
wherein air can be supplied to each compartment of the tube shaped body part and the keel from the compressed air supply part via the air passage tubes, thus inflating the boat.
5. The inflatable boat according to claim 4 , wherein said air distributor comprises a plurality of first over pressure relief valves installed at each compartment to supply compressed air from the air supply passages to each compartment of the tube shaped body part.
6. The inflatable boat according to claim 4 , wherein said air connection part comprises a connection hose connected from the tube shaped body part to the keel for supplying air from the tube shaped body part to the keel.
7. The inflatable boat according to claim 4 , wherein said air passage tube is formed in a U-shape along an inner side of the tube shaped body part, or is formed in an I-shape at each of both sides.
