摘要： A camera swing head includes a hub having a hole ring including a plurality of radially spaced apart holes. A swing plate is rotatably attached to the hub. An indexing and locking assembly allows the swing to be quickly and easily rotated to a desired position and then locked into place. The indexing and locking assembly may include a lever pivotally attached to the swing plate, and a plunger pivotally attached to a front end of the lever. Pivoting movement of the lever may move the plunger linearly on a radial axis intersecting a center of the hub. A release pin is movable from, a first position, wherein the release pin causes the plunger to be held out from engagement with one of the radially spaced apart holes, to a second position, wherein the plunger is movable into engagement with one of the radially spaced apart holes.

摘要： Apparatus and methods allow the wheels of a camera dolly to be quickly and easily changed by a single person. A dolly jack may have a leg attached to a foot and pivotable relative to the foot about a first axis. A jack rod is attached to the leg spaced apart from the first axis. An arm may be pivotally attached to the leg as desired, to provide greater mechanical advantage in lifting the camera dolly. Dolly wheels may be changed by inserting a jack rod into a receptacle on one side of the camera dolly, with the foot of the jack on the ground and with the jack leg substantially in a non-vertical position. The jack leg rotated into a second position wherein the jack leg is substantially vertical, with the dolly rolling slightly in the direction of the rotation. This lifts the side of the dolly sufficiently so that the front and back wheels, or wheel pairs, on the one side of the dolly are lifted off of the ground, allowing the wheels to be changed.

摘要： A camera dolly or camera crane has an arm pivotably attached to a chassis, and a hydraulic system including a hydraulic cylinder for raising the arm, a hydraulic valve and a valve control. The hydraulic valve has a normal operation mode where opening and closing of the valve is controlled by the valve control. The hydraulic valve is also provided with a float down mode, where the valve remains partially open providing an intentional slight leakage, regardless of operation of the valve control. In float down mode, as soon as the arm reaches its highest point, the arm automatically and instantaneously reverses direction and starts to move back down, in a smooth continuous movement. The hydraulic system may optionally also include a fast down valve, to allow the arm to move down quickly, even when minimally loaded.

摘要： In a telescoping camera crane arm, a second section is telescopically extendible into and out of the first section. The second section divided into a front segment attached to a back segment by a connector, to allow the front segment to be removed from the back segment. An adapter is attachable to the front end of the first section. A camera support attachable to the adapter and to the front end of the front segment. To configure the crane for increased maximum payload, the front segment is removed from the back segment. The adapter is attached to the front end of the front section, and the camera support is attached to the adapter, so that the camera support is then supported directly by the first section. A spring balancing system compensates for out-of-balance forces associated with changes in the elevation angle of the crane arm.

摘要： An adapter for a steering handle of a camera dolly includes a first part and a second part attached to the first part in a way that allows for angular adjustment between them. This allows the steering handle to be aligned or squared up relative to the dolly chassis. The first part may be an adapter base and the second part may be a riser. The adapter base may have a flange with slotted holes alignable with holes in the riser. Fasteners, such as cap screws, extending through the slots and holes, may be loosened to allow angular movement between the adapter base and the riser. Once properly aligned, the fasteners are tightened. Grooves, openings, pins, or similar engagement features may be provided at the top end of the adapter base, to allow a steering handle to attach to, and to rotate with, the adapter base. A bore may extend through the adapter base and the riser, with a fitting on the riser adapted to engage with a steering system in the camera dolly. When installed on a camera dolly, the adapter allows the steering handle to align as desired. The adapter also raises the steering handle up, to allow for ergonomic use by a taller dolly operator.

摘要： A telescoping camera crane has mechanical drive and camera platform leveling systems, allowing for water resistant or submerged operation. Telescoping sections of the crane arm are driven by a hydraulic system, for smooth and near silent extension and retraction movement. The telescoping sections of the crane arm have a slight upward curvature, to compensate for deflection the arm, thereby improving performance. Electronic and mechanical stopping systems allow the camera platform to be smoothly, accurately, and reliably positioned. Camera platform levelling and stabilizing systems keep the camera level.

摘要： A remote camera head has a tilt frame attachable to a pan frame at multiple positions. A roll frame is attachable to the tilt frame at multiple positions. The camera head can be expanded or reduced in size as needed based on the space requirements of the camera and camera accessories mounted on the camera head. Waterproof or sealed slip ring assemblies and connectors allow the camera head to operate in wet environments, or even when submerged in water. The camera head can be quickly installed, set up, balanced, or reconfigured.

摘要： A flashlight has a lens or lenses moveable relative to one or more LED or other light source. The beam of light provided by the LED can be focused and provides a uniform light pattern across the range of focus. The lenses are supported on a front housing section and the LED is supported on a back housing section threaded onto the front housing section. Twisting the front housing section closes a switch providing power to the LED, to turn the flashlight on. One or more circuit modules within the flashlight provides various operating modes including an automatic shut-off timer, to preserve battery life, a dimmer controlled by turning an end cap, a blinking function, and/or a current control function to provide maximum brightness regardless of battery condition.
