An armor ( 111 a ) of a scope unit ( 131 ) and a diaphragm ( 123 ) are arranged to be mutually freely turnable. The shape of an outer section ( 123 c ) of the diaphragm ( 123 ) and the shape of the inside of a scope joint ( 130 a ) of a TV camera unit ( 130 ) substantially agree with each other, and the outer section ( 123 c ) of the diaphragm ( 123 ) and the inside of the scope joint ( 130 a ) engage with each other. In a state in which the outer section ( 123 c ) of the diaphragm ( 123 ) and the inside of the scope joint ( 130 a ) are engaged with each other, a ring screw ( 133 ) is meshed with a thread ( 130 b ) so that the scope unit ( 131 ) and TV camera unit ( 130 ) will unitedly be joined with each other. At this time, since the outer section ( 123 c ) of the diaphragm ( 123 ) is engaged with the scope joint ( 130 a ), the diaphragm and TV camera unit can be turned relative to an objective optical system ( 119 ) and relay optical system ( 121 ) with the optical axis of the relay optical system ( 121 ) as an axis of turning. Moreover, a liquid-crystal shutter 124 in the TV camera unit ( 130 ) has two interceptive areas ( 124 a, 124 b ) which can be switched temporally alternately. The interceptive areas ( 124 a, 124 b ) intercept one of two light beams passing through either of aperture stops ( 123 a, 123 b ).

Tilt lock mechanism for marine propulsion device

A shock absorbing hydraulic actuator comprises a cylinder with first and second pistons slidably disposed therein. The first and second pistons are moveable relative to each other. A poppet is supported by the first piston and is moveable relative to the first piston. In response to hydraulic fluid pressure within a passage of the first piston, the poppet can be caused to move in a direction which opens a passage through the first piston to allow the first piston to move relative to the second piston in response to a shock impact such as that which can result from an outboard motor striking a submerged or floating object. The second piston remains in its original position. A bleed passage allows the first piston to resume its original position next to the second piston after the impact has occurred. This movement towards its original position is caused naturally by the weight of an object supported by the hydraulic actuator, such as an outboard motor.

Hydraulic actuator with shock absorbing capability

The outboard motor of the present invention comprises a pedestal that is attached to a transom of a boat, a motor support platform that is attached to the outboard motor, and a steering mechanism that is attached to both the pedestal and the motor support platform. It comprises a hydraulic tilting mechanism that is attached to the motor support platform and to the outboard motor. The outboard motor is rotatable about a tilt axis relative to both the pedestal and the motor support platform. A hydraulic pump is connected in fluid communication with the hydraulic tilting mechanism to provide pressurized fluid to cause the outboard motor to rotate about its tilting axis. An electric motor is connected in torque transmitting relation with the hydraulic pump. Both the electric motor and the hydraulic pump are disposed within the steering mechanism.

An outboard motor is mounted to a transom of a boat with a pedestal that is attached either directly to the transom or to an intermediate plate that is, in turn, attached to the transom. A motor support platform is attached to the outboard motor, and a steering mechanism is attached to both pedestal and the motor support platform. The tilting mechanism is attached to the motor support platform and to the outboard motor. The outboard motor is rotatable about a tilting axis relative to both the pedestal and the motor support platform. The tilting mechanism is rotatable relative to the pedestal and about a steering axis. The steering axis is generally vertical and stationary relative to the pedestal and is unaffected by the tilting of the outboard motor. The tilting mechanism is rotatable relative to the pedestal and about the steering axis with the outboard motor.

Disclosed herein is a marine propulsion device comprising a transom bracket adapted to be connected to a boat transom, a first pivot connecting a stern bracket to the transom bracket for pivotal movement of the stern bracket relative to the transom bracket about a first pivot axis which is horizontal when the transom bracket is boat mounted, a second pivot connecting a swivel bracket to the stern bracket below the first pivot for pivotal movement of the swivel bracket with the stern bracket and relative to the stern bracket about a second pivot axis parallel to the first pivot axis, a king pin pivotally connecting a propulsion unit including a rotatably mounted propeller to the swivel bracket for steering movement of the propulsion unit relative to the swivel bracket about a generally vertical axis and for common pivotal movement with the swivel bracket in a vertical plane about the first and second horizontal axes, a trim cylinder-piston assembly pivotally connected to the stern bracket and to the swivel bracket, a tilt cylinder-piston assembly pivotally connected to the transom bracket and to the stern bracket, and a fluid conduit system communicating between a source of pressure fluid and each of the tilt cylinder-piston assembly and the trim cylinder-piston assembly and including apparatus operable, during reverse operation of the propulsion unit, for causing initial full extension to the trim cylinder-piston assembly, followed by extension of the tilt cylinder-piston assembly, and for causing initial full contraction of the tilt cylinder-piston assembly, followed by subsequent contraction of the trim cylinder-piston assembly.
