摘要： The object collecting heads for object collecting systems includes several embodiments of object collecting heads including light and heavy-duty object collecting heads. The object collecting heads are used to grasp and convey differently sized and randomly shaped objects from a surface to an object holding bin of the object collecting system and are attached to the object holding bin using an adjustable support assembly. Both object collecting heads have three blocks including an upper block, a lower left block, and a lower right block. The lower blocks are connected to each other and the adjustable support assembly by an angled lower block bracket. The upper block is attached to the lower blocks by spring-loaded hinges, such that the upper block is urged toward the lower blocks to grasp an object therebetween. The light-duty object collecting head is a chain-based head, while the heavy-duty object collecting head is a roller-based head.

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 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 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 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 elevating lift with a stabilized movable base includes a base with extendable legs that provide minimum to maximum adjustable stability during use and transport. A lift system is mounted on the base, and a platform assembly is mounted on top of the lift system for selective raising or lowering. Each extendable leg supports a caster, rendering the base movable, and selective extension and retraction of the legs adjusts the stability of the lift. The plurality of legs can be further driven to simultaneously rotate about the vertical axis to steer the lift. The stabilized movable base is further alternatively used in combination with a stool, providing minimum to maximum stability during use and transport of seating, and multiple elevating lifts may be used to support linked platform assemblies in various configurations.

摘要： The locking pin assembly includes an elongate pin housing and a pin mechanism insertably mounted into a bore in the pin housing. The pin mechanism includes at least one rotator section integral with a pin shaft. A rotation-locking member is integrally attached to the bottom of the pin shaft, the locking member having a non-circular shape. An elongate post having a rotation-locking collar attached to one end of the post is slidable in a keyhole extending through the pin. A non-circular recess is formed in the rotation-locking collar, which selectively receives the locking member therein. A spring is disposed behind the rotation-locking collar. The spring normally biases the locking collar into engagement with the locking member. A key is provided to axially push the post to selectively disengage the locking member for selective rotation of the rotator section between locked and unlocked positions.

摘要： The safety guard mechanism for a lifting device is a mechanism that can automatically deploy a safety guard pivotally mounted to the lower surface of the frame of a portable aerial lift device when the lift is raised. By lowering the guard member, the distance between the lower surface of the base and the ground is decreased. The helical screw-based mechanical device includes a mechanical translator coupled with a rotator, the entire assembly interconnecting the guard member and a scissors-type lift so that raising the lift drives the lowering of the guard member. In the lowered position, the guard prevents tipping of the lift should one or more wheels enter a pothole or other depression. A helical screw latch is included to provide a self-locking feature.

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.
