Abstract
Abstract An aiming device comprising an aiming control rudder bar having at least one shaft rotatably mounted in a fixed frame and urged by a first elastic means to a neutral position. The position of the shaft is associated with the movements of a line of sight of a target to be checked in a predetermined relation. A plate is rotatably mounted on said shaft and the plate and shaft are coupled together through the intermediary of jaws and a second elastic means of higher strength than the first, to drive the plate from the shaft away from the neutral position. The plate can be held by an electromagnetic lock or the like in any fixed position to keep the shaft in a frozen position under the action of the second elastic means. The rotation of the aiming control shaft is thus principally effected against the first elastic means from the neutral position when the plate is not locked and against the second elastic means from the freeze position when the plate is locked in a fixed position.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
174 words
An aiming device comprising an aiming control rudder bar including at least one shaft rotatably mounted iN a fixed frame, the angular position of the shaft being adapted to control the line of sight to a target, first elastic means acting on said shaft to urge the same to a neutral position, a plate rotatably mounted on said shaft, means coupling said shaft and said plate in rotation and including second elastic means of greater strength than the first elastic means, the latter means enabling the plate to follow movement of the shaft from said neutral position and temporary locking means for holding said plate in any fixed angular position to keep the shaft in a position frozen by the coupling means, under the action of said second elastic means, the rotation of the aiming shaft thus being principally effected against the first elastic means from the neutral position when the plate is not locked and against the second elastic means from the frozen position when the plate is locked in a fixed position.
Claim 2
Dependent Claim
174 words
An aiming device comprising an aiming control rudder bar including at least one shaft rotatably mounted iN a fixed frame, the angular position of the shaft being adapted to control the line of sight to a target, first elastic means acting on said shaft to urge the same to a neutral position, a plate rotatably mounted on said shaft, means coupling said shaft and said plate in rotation and including second elastic means of greater strength than the first elastic means, the latter means enabling the plate to follow movement of the shaft from said neutral position and temporary locking means for holding said plate in any fixed angular position to keep the shaft in a position frozen by the coupling means, under the action of said second elastic means, the rotation of the aiming shaft thus being principally effected against the first elastic means from the neutral position when the plate is not locked and against the second elastic means from the frozen position when the plate is locked in a fixed position.
Claim 3
Dependent Claim
49 words
An aiming device as claimed in claim 1, wherein said coupling means comprises two jaws rotatably mounted on the shaft, and stop members operatively on said shaft and on said plate, said second elastic means acting on said jaws to urge the same into abutment with respective stop members.
Claim 4
Dependent Claim
43 words
An aiming device as claimed in claim 2 wherein the coupling means further comprises a disk integral with said shaft, one stop member being on said disk and facing the stop member on the plate, said first elastic means actong on said disk.
Claim 5
Dependent Claim
26 words
An aiming device as claimed in claim 2 wherein said second elastic means comprises a coil spring connected to said jaws and extending around said shaft.
Claim 6
Dependent Claim
36 words
An aiming device as claimed in claim 2 wherein said rudder bar comprises two of said shafts mounted for rotation in two mutually perpendicular directions and a common stick controlling the respective rotation of said shafts.
Claim 7
Dependent Claim
21 words
An aiming device as claimed in claim 3 wherein said stop members extend parallel to one another and to said shaft.
Claim 8
Dependent Claim
36 words
An aiming device as claimed in claim 3 wherein said first elastic means is connected to said disk at a location offset from said shaft to apply a force to said disk to turn said shaft.
Claim 9
Dependent Claim
43 words
An aiming device as claimed in claim 3 wherein the jaws are mounted on the shaft between the disk and plate, said coupling means comprising spring means acting on said disk and plate for urging the same together to clamp the jaws therebetween.
