|20150175182||CAMERA DOLLY - A steering bar engageable with and removable from a steering mode transmission in a camera dolly or pedestal. The steering bar has a handle attached to an upper end of a slot tube, with the slot tube telescopically slidable into or over a base tube, and keyed to the base tube. A shift rod has an upper end connected to a shift cap at the steering bar and a lower end connectable to the steering transmission. A clamp clamps onto the shift rod and is axially movable with the handle bar, to allow shifting steering modes via movement of the shift cap, with the steering bar at any selected height.||06-25-2015|
|20130322996||CAMERA CRANE TRANSPORT VEHICLE - A camera crane carrier includes a vehicle having a front end and a back end. A front elevator is movable vertically between up and down positions, at a forward position on a deck vehicle. A back elevator is movable vertically between up and down positions, at a rearward position, below the deck. A ramp may be provided on the vehicle, with the ramp extendible from the deck at the back end of the vehicle to the ground. The elevators allow a camera crane to be more easily loaded onto the vehicle, and also allow lowering the center of gravity of the loaded vehicle. The vehicle may optionally be used as a camera car when not carrying a camera crane.||12-05-2013|
|20130113599||HAND CONTROLLER FOR A CAMERA CRANE - A controller for a camera crane has a rocker button pivotally supported in or on a controller housing about a first pivot axis. A shaft of an electrical component, such as a variable resistor, is on a second pivot axis spaced apart from the first pivot axis. An arm is attached to the shaft. A spring urges the arm to a center position. Movement of the rocker button moves the arm. Due to the offset of the first and second pivot axes, movement of the rocker button results in proportionally reduced movement of the shaft of the electronic component. Smooth crane arm movements are readily achieved as the controller is less sensitive to the operators hand or finger movements.||05-09-2013|
|20130094000||CAMERA CRANE MOBILE BASE - A camera crane has a telescoping arm on a mobile base. The mobile base has a drive motor assembly at each corner of a chassis. The drive motor assemblies may have an electric motor linked to an axle via gearing, and two or more wheels attached to the axle. The wheels can be set to free wheel, so that the mobile base may be pushed or towed, without back driving the electric motor. The wheels may also be linked to the axle, so that the electric motor can provide torque to each of the wheels. The electric motors may be separately controlled to propel and steer the mobile base.||04-18-2013|
|20130025401||STEERING HANDLE ADAPTER FOR A CAMERA DOLLY - 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. 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.||01-31-2013|
|20120269504||QUICK REPOSITIONER FOR A CAMERA HEAD - An accessory for use on a camera crane has a first plate attachable to an end of the camera crane arm. A second plate is pivotally attached to the first plate and moveable into a first position and into a second position perpendicular to the first position. First and second latches secure the second plate into the first and second positions, respectively. The accessory allows a camera head on a camera crane arm to be quickly and easily reoriented.||10-25-2012|
|20120217718||CAMERA CAR - A mobile camera vehicle has a roll cage or similar structure attached to a chassis. Upper and lower horizontal bars are attached to the vehicle structure. Front and rear vertical bars are each attached to the upper and lower horizontal bars. A lift plate is attached to and vertically moveable on the front and rear vertical bars. A lift plate actuator may be attached to the lift plate and used to raise and lower the lift plate on the front and rear vertical bars. Alternatively, the lift plate may be moved manually. A camera platform is supported on the lift plate. A vertical shock isolator may optionally be supported on the lift plate, and with a camera on the camera platform on the vertical shock isolator.||08-30-2012|
|20120152630||CAMERA CRANE MOBILE BASE - A mobile base for a camera crane includes a front left drive motor assembly, a front right drive motor assembly, a rear left drive motor assembly, and a rear right drive motor assembly, attached to a chassis. Each drive motor assembly may include an electric motor linked to an axle via a gear reduction and at least one wheel on the axle. A middle left drive motor assembly and a middle right drive motor assembly may each also include an electric motor linked to an axle via a gear reduction, at least one wheel on the axle, and a spring suspension assembly attached to the chassis and supporting the axle. An electrical power supply on the chassis may be linked to each of the electric motors.||06-21-2012|
|20120070143||HYDRAULIC STOP VALVE FOR A CAMERA CRANE - A stop valve for a camera support such as a telescoping camera crane may include a valve pin engagable onto a valve seat, with a pin plate attached to the valve pin. A spring urges the valve pin in a first direction, which may be an opening direction or a closing direction. First and second dampener pins in first and second cylinders are attached to the pin plate. A closed loop fluid filled flow path connects the first and second cylinders. First and second check valves may be used to control flow in the flow path.||03-22-2012|
