摘要： The mobile work station with versatile tool handler arm is a mobile work station that carries a tool handler arm that can manipulate a tool in multiple global degrees of freedom. The work station has a base housing mounted on a plurality of wheels. A vertical post is mounted on top of the base housing, the vertical post having relative rotation to the base housing. An elongate tool handler arm is pivotally mounted medially at the top of the vertical post, the tool handler arm being defined by a 4-bar linkage including an upper link, a lower link, and front and rear crank blocks pin-jointed together. An elongate handlebar connected to the rear end of the tool provides control of the tool handler, and a tool carrier attached to the front end allows selective attachment of any one of a variety of tools.

摘要： The simultaneous actuating mechanism for parallel axis rotors includes a base and a plurality of rotating rotors mounted in spaced relation inside the base, the rotors having parallel axes of rotation. A crank pin extends from each rotor at a position offset from the corresponding axis of rotation. A driving assembly is coupled to the crank pin of all the rotors. Operation of the driving assembly causes simultaneous rotation of the rotors to facilitate various mechanical functions, such as threading, steering, and reciprocation of multiple elements.

摘要： The radially engaging systems includes a housing having at least one guide channel formed therein. At least one sliding member is slidably received in the guide channel to selectively extend or retract therein in order to connect and lock mechanical components together. Each sliding member is provided with an elongate follower. A rotator is operatively mounted to the housing. The rotator includes at least one guide curve based upon an Archimedian spiral. The follower rides inside the guide curve. Selective rotation of the rotator converts the rotation into linear movement of the connected sliding member. Conversely, selective linear movement of the sliding member converts the same into rotation of the rotator.

摘要： The linear-to-rotary actuator includes an elongated drive member constrained to linear movement, and a rotary member constrained to rotary movement. The elongated drive member has a coupling end and an engaging member that projects from the coupling end. The rotary member has a track defining an Archimedean spiral. The track is adapted to receive the engaging member. The engaging member is constrained to slide in the track such that linear movement of the elongated member effects rotation of the rotary member. The track may be a slot, a groove, or other guide. Alternatively, instead of a track defined directly in the rotary member, the actuator may include a linking member (such as a disk or rectangular bracket) attached to the rotary member, the linking member having a track defining an Archimedean spiral defined therein, the engaging member being slidable in the track to convert linear motion into rotary motion.

摘要： The linear-to-rotary actuator is a device that has two rotors at opposite ends of a main housing tube, the rotors being driven to rotate by a slider disposed between the rotors, the slider being attached to the piston of a linear actuator. The device may be configured so that angular displacement between the rotors may be adjusted for use with apparatus that may require variable angular displacement between articulated segments, such as a robotic arm, the arm of an excavator or crane, and the like. In one embodiment, the device has rollers mounted on opposite sides of the slider that engage tracks defined in adaptors selectively coupled to the rotors by “boltless” connectors. In another embodiment, the device has gear trains driven by the slider that are coupled to the rotors for multiplying angular displacement between the rotors.

摘要： The elevating lift includes a stabilizer base with extendable legs to provide minimum to maximum stability during use and transport. A lift system is fixed to the stabilizer base, and a platform assembly is mounted to the top of the base to be selectively raised or lowered by the lift system. The lift system utilizes a plurality of telescoping cage assemblies interconnected to extend or retract relative to each other. A drive assembly with an extendable lift mast is mounted to the stabilizer base to act on the cage assemblies to raise or lower the same. A drive train coupled to the telescoping cage assemblies enables relative extension and retraction of the cage assemblies. An adjustable guardrail is mounted to a platform of the platform assembly to provide safety for the user.

摘要： The radially engaging coupling system comprises numerous embodiments for connecting two or more concentric components with radially extending or retracting bolts. Most embodiments include a ring having a plurality of Archimedean spiral slotted segments. Each bolt has a pin extending laterally therefrom to engage a corresponding slot in the ring. Rotation of the ring drives the pins and their bolts outward or inward to engage or disengage an outer component. Some embodiments have inwardly or outwardly spaced pin passages in the ring, rather than the spiral slots. The disc may comprise a snap ring. Another embodiment has two axially spaced spirally slotted rings, with a plurality of cylindrical rollers therebetween. Rotation of the rings drives the rollers inward or outward to engage corresponding axial grooves in the inner shaft. In another embodiment each bolt has an arcuate segment extending thereacross, to engage a corresponding circumferential groove in an outer component.

摘要： The radially engaging systems includes a housing having at least one guide channel formed therein. At least one sliding member is slidably received in the guide channel to selectively extend or retract therein in order to connect and lock mechanical components together. Each sliding member is provided with an elongate follower. A rotator is operatively mounted to the housing. The rotator includes at least one guide curve based upon an Archimedian spiral. The follower rides inside the guide curve. Selective rotation of the rotator converts the rotation into linear movement of the connected sliding member. Conversely, selective linear movement of the sliding member converts the same into rotation of the rotator.
