WO1996030087B1 - Boat for divers - Google Patents

Abstract

The proposal is for a boat for divers in the hull (1) of which there is a flow channel (5) with a propulsion screw (15) with, in the hull (1) above said flow channel (5), an electric motor (11) and other control devices, the bow of which has a hydrodynamic configuration (4).

Claims

 CHANGED CLAIMS [received at the International Bureau on October 9, 1996 (09.10.96); original claims 1-14 replaced by amended claims 1-12 (4 pages)] Motor watercraft with a streamlined hull (1), with a running substantially in the longitudinal direction i m Hull arranged by the water flowed through Flow channel (3), wherein the flow channel upstream of an inflow opening in the front half of the hull, which is slightly curved towards the fuselage bottom, and downstream of an outlet opening on Rear, which is slightly curved towards the fuselage bottom, with a What serzeug serving Water screw (13) in the flow channel (3), with one with the water screw (13) coupled Electric motor (8) including its control unit, with an electric battery (7) having Energy source, with on the sides of the fuselage (1) arranged handles (2) for the person controlling the watercraft, with a device for controlling the engine speed Water screw (13) on at least one of the handles, characterized 17 that the handle are arranged in the front to middle portion of the fuselage, that the person controlling the motor watercraft is at least partially on the motor watercraft, that the nose of the fuselage has a flow structure that largely bypasses the fairway flow past the person that the battery in a separate removable and attachable to the trunk container is arranged and that handles (2) and hull are ergonomically designed to allow in conjunction with the person (in particular by their weight transfer) the control of the motor watercraft. 2. Motor watercraft according to claim 1, characterized in that the battery-containing container is disposed on the fuselage underside, that the container in the direction of travel of the watercraft is removable and that the electrical connection of the container and the battery via a connector between the fuselage underside and container top takes place. 3. Motor watercraft according to claim 1 and 2, characterized in that the electric motor is arranged outside the flow channel in the fuselage. 4. Motor watercraft according to one of the preceding claims, characterized in that the free spaces (6) in the hull (1) are at least partially filled with foam. 5. Motor watercraft according to one of the preceding claims, characterized in that a 18 Floating bladder with the hull (1) is connected, the volume of which can be increased or decreased if necessary for the emergence and emergence. 6. Motor watercraft according to one of the preceding claims, characterized in that in the hull (1) is arranged from the outside accessible and sealed inside rope bag. 7. Motor watercraft according to one of the preceding claims, characterized in that upstream of the water screw (13) in the flow channel (3) fins for filtering foreign objects are present. 8. Motor watercraft according to one of the preceding claims, characterized in that the speed controlling device when releasing the handle (2) is set by the person directly to zero speed. 9. Motor watercraft according to one of the preceding claims, characterized in that the shaft (11) of the water screw (13) in a bearing block (22) is arranged, which via radial struts (23) attached to the wall (14) of the flow channel (3) is. 10. Motor watercraft according to one of the preceding claims, characterized in that the shaft (11) of the water screw (13) in a tube (21) is guided, which the wall (14) of the flow channel (3) in the region of curvature under a certain Angle sealed penetrates and on the other hand sealingly fixed to the bearing block (22). 19 11. Motor watercraft according to one of the preceding claims, characterized in that between the shafts of the water screw (13) and the electric motor (8) has a transmission (9) is present (belt drive or gear transmission). 12. Motor watercraft according to one of the preceding claims, characterized in that on the lateral surface of the hull (1) display devices for battery charging, diving depth udgl. are arranged in the field of view of the diver.
