Operator supported remote camera positioning and control system with support vest

Abstract

A remote camera positioning and control system is disclosed that permits a sole operator to use and support a camera out of arm's reach. Various features of such a remote camera positioning and control system are disclosed. The positioner can include one or more beam modules having cross-sectional flexural rigidity that varies along the length of the beam module(s) by use, for example, of stiffening longerons, anchoring braces and relatively low density stabilizing webs. The camera can be mounted to the beam module by a front end assembly that is constructed to place the center of mass of the camera and the front end assembly along the neutral axis of the beam module over as great a range of motion as possible. The system can also include a handle module that incorporates, for example, an axially and rotationally moveable grip and a proximal handle grip ring and control cage for surrounding a camera control, such as a joystick. Auxiliary subsystems, such as a monitor, video recorder and battery packs can optionally be worn by the operator using a support garment, such has a vest.

Description

CROSS-REFERENCE TO RELATED APPLICATION [0001] This application is a continuation of prior application Ser. No. 10 / 387,192 filed Mar. 11, 2003.FIELD OF THE INVENTION [0002] The invention relates to camera supports. More particularly, the invention relates to supports for remotely positioning cameras. BACKGROUND OF THE INVENTION [0003] In cinema graphic and other visual art endeavors, it is often desired to increase the range of viewing perspectives, to obtain various special effects and capture scenes from angles and elevations that are not available from a camera on a tripod or held by a camera man. This is particularly true in the recording of sporting events. Various systems have been developed to address these goals, including elevating and pivoting boom arms, as shown, for example, in U.S. Pat. No. 4,849,778, and steady cam mounts for aircraft, as shown, for example, in U.S. Pat. No. 4,156,512. [0004] While these approaches do increase the range of viewing angles and elevations,...

AI Technical Summary

Benefits of technology

[0007] It is desirable for a remote camera positioning system having features according to aspects of the invention to be sufficiently light-weight to be borne and readily maneuvered by a sole operator, but have sufficient flexural rigidity to resist the various deflections that can be induced by loads created with the camera movements and by external forces. Various combinations of features according to principles of the invention can provide a balance between such light-weightness and flexural rigidity to enable sole operator use and control in a self-contained manner.

[0012] The flexural rigidity in the anchor braces can decrease by reducing the thickness of the anchor braces located at more distal locations toward the camera. Similarly, the thickness and density of the stabilizing web material can be reduced to decrease the cross-sectional flexural rigidity at more distal locations towards the camera. Another possibility, either alone or in combination with these two techniques, is to reduce the diameter or other cross-sectional detail of the longerons.

[0013] In another embodiment having features according to aspects of the invention, the longerons can extend substantially the entire length of the beam module. Alternatively, the longerons can be removably connected between adjacent beam modules. The longerons and the associated beam modules can even be removably connected by hand adjustable connectors to avoid the need for tools and to provide the ability to fine tune the parallel arrangement of the longerons along the length of the positioner.

[0028] Another embodiment having features according to aspects of the invention can include hand adjustable connectors between the various adjustable and disassemble-able components of the positioner to permit field adjustments and assembly and disassembly without tools. Most, if not all, of the hand adjustable fasteners could be nylon to reduce the mass of the positioner. Nylon fasteners can also provide “weak points” that can break away under impact with foreign objects before more expensive components are damaged by the collision.

Problems solved by technology

While these approaches do increase the range of viewing angles and elevations, they often involve complicated componentry that is typically difficult to operate by a cameraman alone and is almost certainly too large to be held and maneuvered by a cameraman alone.

The size and weight of the equipment often limits access to desired viewing and recording areas.
