A rotation shaft assembly includes first and second rotation shafts configured to be connected to first and second bodies, respectively, a synchronization mechanism disposed between and transmissively connected to the first and second rotation shafts, and a control mechanism including first and second followers sleeved at the first and second rotation shaft, respectively, and a lock member disposed between the first and second rotation shafts. In a first state of the first and second bodies flipping relative to each other, the lock member interacts with the first or second follower to fix the first or second rotation shaft. In a second state of the first and second bodies flipping relative to each other, action of the lock member on the first and second followers is released, and the first and second rotation shafts rotate synchronously through the synchronization mechanism.

The invention relates to an indirect rear viewing system for a motor vehicle having a supporting element for fastening at least one reflective element, wherein the supporting element has a coupling region for a position variable fastening/attachment to an adjusting element, which in turn can be attached to the vehicle, wherein the coupling region contacts a counter contact regions, of the adjusting element, wherein interlocking anti rotation means are present on the supporting element and on the adjusting element, wherein the anti rotation means are forming an index geometry, which, in a first operating state, permits an adjustment of the supporting element relative to the adjusting element about two axes of rotation, which are transverse to one another, and, in at least a second operating state, permits a basic position change of the supporting element relative to the adjusting element about a third axis of rotation which is aligned transversely to the two other axes of rotation.

An adapter device for detachably fastening instruments and equipment to a side rail of an operating table includes a clamping device by means of which the adapter device can be clamped to the side rail of the operating table, a longitudinal profile onto which the instruments and equipment can be detachably fastened, and a joint having at least one pivot axis formed between the clamping device and the longitudinal profile so that the longitudinal profile is pivotable relative to the clamping device about the pivot axis of the joint.

A manufacture configured to and process for inhibiting, from wear, a lock in a latching system comprising: a gland surrounding an actuator translating the lock through: a first fixed lock receptor and a moveable lock receptor. The manufacture and process include: inhibiting a skewing, of a lock central axis of the lock with the lock translating through the first opening and the opening in the moveable lock receptor, away from substantially aligning with: a first central axis of a first opening of the first fixed lock receptor, and an actuator central axis of the actuator, via fitting a first translation guide into the first fixed lock receptor. Also included is inhibiting: wear of a gland around an actuator in the lock while translating, and leaking, past the gland, of an actuator fluid within the lock; and skewing of an actuator central axis of the actuator.

A system includes a base, and an actuator having a first end and a second end. The system also includes a shaft configured to rotate relative to the base, and a drive link fixed to the shaft. The system further includes a support arm. A first end of the support arm being fixed to the shaft such that rotation of the shaft causes commensurate rotation of the support arm. The system also includes a timing link having a first end pivotably connected to the base and a second end opposite the first end. Additionally, the system includes a mount coupled to the second end of the timing link. The mount is configured to maintain a substantially constant orientation relative to the base as the support arm transitions between a raised position and a lowered position.

Particular embodiments disclosed herein provide a joint of a tray arm assembly, comprising a joint body, a shaft configured to rotate relative to the joint body about a longitudinal axis of the shaft, and a slip clutch assembly, comprising a clutch stack, including a plurality of first clutch plates keyed to the shaft and a plurality of second clutch plates keyed to the joint body. The clutch stack further comprises a spring configured to selectively exert a force on the clutch stack, wherein the force compresses the clutch stack causing a friction between the plurality of first clutch plates and the plurality of second clutch plates with respect to a rotation of the shaft relative to the joint body.

A rotation shaft assembly includes a first lock accessory, a second lock accessory, a rotation shaft, a driven member, and a torsion mechanism. The rotation shaft includes a first member and a second member that are rotatable relative to each other, where the first member is fixedly connected to the first lock accessory, and the second member is fixedly connected to the second lock accessory. The driven member is connected to the first member or the second member, and is configured to be driven to rotate by the first member or the second member. The torsion mechanism is at least provided at the driven member and is configured to provide torsion during rotation.
