Abstract
A braking system for a small jet propulsion surfboard can be manufactured at reduced costs. The braking system includes left and right sponsons retractably attached to a surfboard body. Left and right locking units fix the sponsons to the surfboard body. An unlocking unit unlocks the lock units in order to free the sponsons from the surfboard body. A traction rope ensures that the freed sponsons remain connected to the surfboard body. The freed sponsons are pulled by the traction rope to thereby apply braking force to the jet propulsion surfboard. In an alternative embodiment, a system with a water-reversing cup can replace the sponsons.
Claims25
A braking system for a small jet propulsion surfboard, comprising:
- a braking unit retractably attached on a surfboard body, the braking unit includes a pair of sponsons attached to opposite sides of the surfboard body;
- a locking unit for fixing the braking unit to the surfboard body;
- an unlocking unit for unlocking the locking unit for freeing the braking unit;
- and
- a traction rope for keeping the freed braking unit connected to the surfboard body, wherein the braking unit is pulled by the traction rope and applies braking force to the surfboard, the traction rope includes at least one traction rope and wherein each of the sponsons are tethered to the surfboard body by the at least one traction rope.
A braking system for a small jet propulsion surfboard, comprising:
- a braking unit retractably attached on a surfboard body, the braking unit includes at least one sponson, the sponson having at least one pivotable plate which moves to an open position when the unlocking unit unlocks the braking unit;
- a locking unit for fixing the braking unit to the surfboard body;
- an unlocking unit for unlocking the locking unit for freeing the braking unit;
- a traction rope for keeping the freed braking unit connected to the surfboard body, wherein the braking unit is pulled by the traction rope and applies braking force to the surfboard;
- and
- a pair of plates are provided for the at least one sponson, the plates being movable away from one another when moving to the open position, the plates being held in a closed position when the at least one sponson is locked on the surfboard body.
A braking system for a small jet propulsion surfboard, comprising:
- a braking unit retractably attached on a surfboard body, the braking unit includes a pair of sponsons, each of the pair of sponsons having a pair of locking arms and one of the pair of locking arms being independently movable relative to another of the pair of locking arms in opposed directions to release the braking unit during unlocking;
- a locking unit for fixing the braking unit to the surfboard body;
- an unlocking unit for unlocking the locking unit for freeing the braking unit;
- and
- a traction rope for keeping the freed braking unit connected to the surfboard body, wherein the braking unit is pulled by the traction rope and applies braking force to the surfboard.
A braking system for a small jet propulsion surfboard, comprising:
- a braking unit retractably attached on a surfboard body, the braking unit includes a braking button on the surfboard body, at least one turn sensor and a controller;
- a locking unit for fixing the braking unit to the surfboard body;
- an unlocking unit for unlocking the locking unit for freeing the braking unit;
- and
- a traction rope for keeping the freed braking unit connected to the surfboard body, wherein the braking unit is pulled by the traction rope and applies braking force to the surfboard, wherein
- the controller receives a signal from at least one of the braking button and the at least one turn sensor in order to unlock the locking unit and the at least one turn sensor includes a left and right turn sensor and wherein the braking unit includes a right and left sponson, the controller releases the left sponson in response to at least a signal from the left turn sensor, the controller releases the right sponson in response to at least a signal from the right turn sensor and the controller releases both sponsons upon receipt of a signal from the braking button and lack of receipt of a signal from the left and right turn sensor.
A braking system for a small jet propulsion surfboard, comprising:
- a braking unit retractably attached on a surfboard body, the braking unit includes a water-reversing cup which is attached to a nozzle for injecting water rearward from a bilge and reverses injected water;
- a locking unit for fixing the braking unit to the surfboard body;
- an unlocking unit for unlocking the locking unit for freeing the braking unit;
- and
- a traction rope for keeping the freed braking unit connected to the surfboard body, wherein the braking unit is pulled by the traction rope and applies braking force to the surfboard, the traction rope includes a pair of traction ropes attached to the water-reversing cup and wherein the braking system further comprises a pair of winches connected to respective traction ropes.
