This application is related to International Application No. PCT/CA2017/050376 filed on Mar. 24, 2017 with the Canadian PCT Receiving Office, and International Application No. PCT/CA2018/051193 filed on Sep. 21, 2018, said applications incorporated hereinto by reference.
The present disclosure relates to modular utility equipment and in particular to modular pulley components for demountable engagement into various configurations of modular assemblies for use in engagement and/or support and/or operation and/or conveyance of equipment for multiple utility purposes.
Utility equipment of various forms is used in almost every industry and can range vastly in both size and complexity in order to meet the particular needs of the given industry. The filmmaking industry is one such field requiring various specialized utility equipment. Cinematic techniques in filmmaking, videography, and photography have increased in both scale and complexity. Such cinematic techniques depend on a wide range of utility equipment, in particular camera and lighting support equipment, that provide filmmakers with the technical means to create desired camera shots needed for a scene or a cinematographic effect.
Various types of camera motion support equipment are available and are widely used by filmmakers and photographers. Some commonly used equipment include, for example, handheld and body-supported stabilizers and gimbals which allow for a smooth shot to be taken while the operator is walking, while maintaining the ability to control the pan and tilt movements of the camera. Jibs or cranes provide the ability to add vertical and sideways movement to a shot, and the ability to achieve a high angle shot, depending on the size of the jib. Various types of dollies similarly range in size from the very large to smaller systems to provide smooth rolling camera movement thereby enabling the addition of horizontal motion to a shot.
Sliders, for another example, are essentially a condensed, mountable version of a dolly on a supported track and provide smooth movement along a straight horizontal path. For performing a straight up and down vertical tracking movement, however, existing vertical slider or dolly systems are of limited functionality because they have only short vertical ranges of motion.
There are various other industries that have similar problems with equipment availability, materials support, and functionality, such as for example, staging, lighting, and sound support configurations for live events, construction sites, warehousing, and the like.
The present disclosure generally relates to sturdy and durable pulley system assemblies for use on a work site or other location wherein the assemblies are configured by interconnecting and securely engaging pulley and cable components with a plurality of modular structural support components and with other selected modules configured for mounting and moving of tools or equipment or instruments or materials around a space.
According to some embodiments disclosed herein, the present pulley system assemblies are configured for engaging, lifting, supporting, manipulating, and moving of cameras, lights, microphones, tools, power tools, sensors, or other equipment or devices or materials, and other types of loads along a vertical path using pulley and cable components fastened by eyebolt or other means to a load support subassembly whereby the supported load may be raised and lowered. According to one aspect, the present pulley system assemblies may cooperate with a rail-rolling module engaged with a vertical rail provided therefore, for more precisely controllable raising and lowering of the supported load. According to another aspect, the weight of a load support assembly and supported load thereon may be counterbalanced by an opposing weighted subassembly, which may also cooperate with a rail-rolling module engaged with a vertical rail provided therefore. According to another aspect, modular assemblies comprising the present pulley system assemblies disclosed herein, may additionally have wheel or caster components to provide a transportable rolling movement of the modular assemblies within and about work site.
More specifically, the present disclosure relates to three types of pulley support assemblies configured for demountable engagement with the structural modules of a vertical track system assembly.
An example of an embodiment of the pulley system assemblies disclosed herein pertains to a first type of pulley support assembly which has a pair of opposed pulley modules having an elongate structural element interposed the two pulley modules which are attached to end plates at both ends of the elongate structural element.
Another example of an embodiment of the pulley system assemblies disclosed herein pertains to a second type of pulley support assembly which has a pair of opposed pulley modules that include male end connectors for demountable engagement of the pulley modules with another module of the system with female ends.
Another example of an embodiment of the pulley system assemblies disclosed herein pertains to a third type of pulley support assembly that has a pair of opposed pulley modules wherein the modules' pulley brackets are repositionable to varying angular orientations by alternating screw mount positions selected on mount components at opposite ends of an elongate structural element.
