Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
192 words
An apparatus for remotely controlling a plurality of marine propulsion units for providing a propelling force for a marine vessel, each propulsion unit having a propeller movable about a horizontal tilt axis which is transverse to the direction of movement of the marine vessel, comprising: a plurality of control levers, each control lever being operably connected to a respective marine propulsion unit and adapted to control a clutch and a throttle operation of the respective marine propulsion unit; and a plurality of tilt and trim switches disposed in a lever grip of a single control lever and performing at least one of a displacing operation in the tilt angle of the respective propeller around a pivotal point, and an adjusting operation in the trim angle of the respective propeller around the pivotal point to adjust the direction of the propelling force, each switch being operatively connected to a respective marine propulsion unit for controlling movement of the propeller of the propulsion unit about the horizontal tilt axis, whereby an operator of the marine vessel can simultaneously operate the tilt and trim switches and said plural control levers by using a single hand.
Claim 2
Independent Claim
192 words
An apparatus for remotely controlling a plurality of marine propulsion units for providing a propelling force for a marine vessel, each propulsion unit having a propeller movable about a horizontal tilt axis which is transverse to the direction of movement of the marine vessel, comprising: a plurality of control levers, each control lever being operably connected to a respective marine propulsion unit and adapted to control a clutch and a throttle operation of the respective marine propulsion unit; and a plurality of tilt and trim switches disposed in a lever grip of a single control lever and performing at least one of a displacing operation in the tilt angle of the respective propeller around a pivotal point, and an adjusting operation in the trim angle of the respective propeller around the pivotal point to adjust the direction of the propelling force, each switch being operatively connected to a respective marine propulsion unit for controlling movement of the propeller of the propulsion unit about the horizontal tilt axis, whereby an operator of the marine vessel can simultaneously operate the tilt and trim switches and said plural control levers by using a single hand.
Claim 3
Dependent Claim
22 words
An apparatus as claimed in claim 1 wherein each control lever comprises locking means for locking the control lever against pivotal movement.
Claim 4
Dependent Claim
45 words
An apparatus as claimed in claim 1 wherein each control lever is pivotally mounted for pivoting so as to control the clutch and throttle operation of the respective marine propulsion unit and each control lever comprises said grip in which a respective switch is disposed.
Claim 5
Dependent Claim
24 words
An apparatus as claimed in claim 3 wherein each control lever further comprises a locking member for locking the control lever against pivotal movement.
Claim 6
Dependent Claim
23 words
An apparatus as claimed in claim 4 wherein each locking member is operable to lock its associated control lever at a neutral position.
Claim 7
Dependent Claim
154 words
A remote control apparatus for controlling a plurality of marine propulsion units for providing a propelling force to a marine vessel, each unit having a propeller, said apparatus comprising: a plurality of control levers respectively disposed corresponding to the marine propulsion units, each of the control levers performing a clutch and a throttle operation of each of the marine propulsion units; and a plurality of tilt and trim switches for performing at least one of a displacing operation in the tilt angle of the respective propeller around a pivotal point, and an adjusting operation in the trim angle of the respective propeller around the pivotal point to adjust the direction of the propelling force, said plurality of switches being disposed in only a lever grip of one of the control levers such that said plurality of tilt and trim switches and said plural control levers can be simultaneously operated by using a single hand.
Claim 8
Dependent Claim
154 words
A remote control apparatus for controlling a plurality of marine propulsion units for providing a propelling force to a marine vessel, each unit having a propeller, said apparatus comprising: a plurality of control levers respectively disposed corresponding to the marine propulsion units, each of the control levers performing a clutch and a throttle operation of each of the marine propulsion units; and a plurality of tilt and trim switches for performing at least one of a displacing operation in the tilt angle of the respective propeller around a pivotal point, and an adjusting operation in the trim angle of the respective propeller around the pivotal point to adjust the direction of the propelling force, said plurality of switches being disposed in only a lever grip of one of the control levers such that said plurality of tilt and trim switches and said plural control levers can be simultaneously operated by using a single hand.
