Abstract

Abstract A positioner for adjusting inclination and position of an object from one control direction, in which inclination of the object along the control direction is adjusted by rotating in the same direction gear pieces respectively attached at opposide ends of the object by means of two rotation shafts provided in parallel so as to be meshed respectively with the gear pieces in response to rotation of a first control shaft, which is provided in the control direction and engaged with the two rotation shafts to drive them in the same rotation direction. The slide movement of the object along a direction perpendicular to the control direction is controlled by sliding the gear pieces along the two rotation shafts in response to the rotation of a second control shafts, which is provided in the control direction and engaged with the gear pieces through a gear mechanism. The inclination of the object along a direction perpendicular to the control direction is controlled by slidably supporting the object at opposide ends by supporting shafts on the same axis and by rotating the object about the axis in response to a control shaft, which is provided on one of the gear pieces along the control direction to rotate the object through a gear mechanism. The slide movement of the object along the control direction is controlled by shifting the object along the supporting shafts by use of screw mechanism between one of the gear pieces and one of the supporting shafts in response to rotation of a control shaft, which is provided on the one of the gear pieces along the control direction to totate the one of the supporting shafts through a gear mechanism.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 142 words
A positioner comprising, a support element on which an object to be positioned in three dimensions is disposed, means defining an axis of rotation for said support element terminating in two axially spaced gear sectors for tilting said axis of rotation about a second axis normal to the axis of rotation, means comprising gear means meshing with said gear sectors for tilting said axis of rotation, means to translate said means defining said axis of rotation to translate said axis of rotation along said second axis in two opposite directions, means to translate said means defining said axis of rotation laterally along said axis of rotation thereby to translate said support element laterally in opposite directions, and means to rotate said means defining said axis of rotation about said axis of rotation, whereby said support element is adjustably positionable in three dimensions.
Claim 2
Dependent Claim 142 words
A positioner comprising, a support element on which an object to be positioned in three dimensions is disposed, means defining an axis of rotation for said support element terminating in two axially spaced gear sectors for tilting said axis of rotation about a second axis normal to the axis of rotation, means comprising gear means meshing with said gear sectors for tilting said axis of rotation, means to translate said means defining said axis of rotation to translate said axis of rotation along said second axis in two opposite directions, means to translate said means defining said axis of rotation laterally along said axis of rotation thereby to translate said support element laterally in opposite directions, and means to rotate said means defining said axis of rotation about said axis of rotation, whereby said support element is adjustably positionable in three dimensions.
Claim 3
Dependent Claim 84 words
A positioner according to claim 1, in which said support element comprises two axially spaced bores, said means defining said axis of rotation comprising two shafts each disposed in one of said bores and terminating in said gear sectors, said means for tilting said axis of rotation comprising two parallel shafts each having a pinion gear meshing with one of said gear sectors, a third control shaft for rotating said two parallel shafts, and gears coupling said third control shaft and said parallel shafts.
Claim 4
Dependent Claim 83 words
A positioner according to claim 2, in which said means to translate said axis of rotation comprises gear boxes at opposite ends of the axis of rotation each mounting one of said pinion gears and being slidable relative thereto, a pair of parallel gear racks coupled to corresponding ones of the gear boxes, and a rotatable rod having gears thereon meshing with said gear racks for moving them jointly longitudinally thereby to translate said support element in opposite directions along said second axis.
Claim 5
Dependent Claim 78 words
A positioner according to claim 3, in which said means to translate said means defining said axis of rotation comprises a gear element, a shaft coupled to said support element defining a part of said axis of rotation, and threaded in said gear base element, means to rotate said shaft in opposite directions to move it axially relative to said gear base element thereby to translate said support element laterally in opposite directions along said axis of rotation.
Claim 6
Dependent Claim 65 words
A positioner according to claim 4, in which said means to rotate said means defining said axis of rotation comprises a gear coupled to said shaft defining a part of said axis of rotation, a drive gear meshing with the last-mentioned gear, means rotatably supporting said drive gear on said gear base element, and means to rotate said drive gear thereby to rotate said shaft.
Claim 7
Dependent Claim 31 words
A positioner according to claim 1, including a base having four openings adjacent corners thereof for receiving removable legs therethrough, and means to tighten said legs when disposed in said openings.
Claim 8
Dependent Claim 79 words
A positioner according to claim 1, in which said means comprising gear means meshing with said gear sectors for tilting said axis of rotation comprises for each gear sector a threaded element adjacent a corresponding gear sector and a gear having a threaded bore receiving said threaded element, each threaded element having a worm gear thereon, and a shaft having a worm gear meshing with the first-mentioned worm gear for moving said threaded gear axially on said threaded element.
