发明名称 Intake clearing tool for jet-powered aquatic vehicles
摘要 An intake clearing tool for jet-powered aquatic vehicles has an elongated handle portion, attachment means at one end for receiving a complementary attachable finger-type rake head and a handle grip at the opposite end. The handle grip end is adapted to receive a 90 DEG extension handle to enable the rake tool to be manipulated from alongside or on board a vehicle. In the preferred embodiment, the elongated handle is extensible and includes a first part which is sealed at both ends to contain an air chamber therein so that the handle will be capable floating rather than sinking. The handle portion preferably made of at least two tubular plastic telescoping rods has an attachment means at one end preferably in the form of screw threads that receives a rake tool head with a corresponding screw attachment and the opposite end has a resilient handle grip that may include an over-the-wrist securing loop. The rake head attachment has substantially v-shaped and barb tipped fingers that are perpendicularly disposed. An interlocking mechanism secures the telescoping rod members in their extended position against both collapsing and rotation. An end plug on the inner rod member is provided with an o-ring seal and the outer end of the outer rod has a flap valve such that the telescoping action of the rods forms a pump that may be used to remove water from a compartment. An alternative form has tubular metal rods that fit together with spring biased lock pins.
