SELF SUPPORTING AND PORTABLE AERIAL RIGGING STRUCTURE FOR AERIALISTS
Presented is a rigging structure with a mechanical advantage of being lifted and suspended above the ground surface using one or more pulley block and tackle systems and/or winch systems. The rigging structure includes a pivoting head portion, four legs, and four feet. The head portion includes a central shaft held between a pair of holders. Each of the holders includes a pair of legs connecting arms. Each of these legs connecting arms is connected to a first leg section and one or more second leg sections and finally to feet to form the legs. The bottom of the legs or feet is interconnected using metal or non-metal wires for preventing any buckling effect due to load attached to the rigging structure. The bottom of the legs are connected by pulling first pair of legs towards second pair or legs or vice versa using pulley block and tackle system capable of exerting required pull force.
This patent application claims the benefit of priority of U.S. Provisional Application No. 63/243,766, entitled “self-supporting and portable aerial rigging structure for aerialists,” filed 14 Sep. 2021, which is hereby incorporated herein by reference in its entirety.
TECHNICAL FIELDThe present invention relates generally to rigging systems and in particular to a self-supporting and portable rigging structure using the mechanical advantage to be raised and suspended above the ground surface using one or more pulley block and tackle systems and/or winching systems.
BACKGROUNDAerialists (E.g., Aerial dancers, acrobats, gymnasts) often combine their incredible strength with mesmerizing movements to dance or perform various moves through the air. Most of the aerial performances are performed on silks, Lyra, trapeze, hammocks, or a custom apparatus of the performer's choice.
Many of the pre-existing three-legged and four-legged aerial rigging structures are known to have height adjustment capability. Mostly, head portions and legs connecting arms formed on the head portion of such structures are fixed. After connecting the legs to the legs and connecting arms at the bottom of the head portions of such structures, the users are required to manually lift the positions of the legs or feet by sighting up each leg to straighten the legs as needed. This requires a lot of effort from users, the involvement of many people, and also requires the users to move around the rigging structures several times to get the rigging structures assembled correctly in the desired position. Due to having the fixed head portion and legs connecting arms, such known structures cannot be raised, assembled, and suspended above the ground surface using available mechanical advantages such as winching systems or similar mechanical systems.
Thus, what is required is a self-supporting, mechanized, and portable rigging structure using the mechanical advantage to allow the rigging structure to be raised, assembled, and suspended above the ground surface using one or more pulley block and tackle systems and/or winches.
SUMMARYIt is an objective of the present invention to provide a rigging system or a novel rigging structure that's portable and easy to set up and disassemble.
It is another objective of the present invention to provide a self-supporting and portable rigging structure that can be raised, assembled, and suspended above the ground surface with lesser manpower and effort.
It is another object of the present invention to provide a rigging structure with provisions on all the feet for interconnecting the legs of the rigging system together using a metal or non-metal wire so as to reduce or prevent buckling effect on the legs when the system has a load suspended from it.
It is another objective of the present invention to provide a rigging structure that's safe and versatile and can be installed or configured in a variety of venues where performances need to be performed with ease. The proposed rigging structure is designed to support almost all kinds of props or equipment suitable for performing a variety of acts or for performances by aerial artists, gymnasts, acrobats, and others. The invention is also useful for training acrobats, divers, circus performers, stunt skiers, dancers, and the like, it is primarily intended for use in training aerialists and is accordingly described in that context.
These and other features and advantages of the present invention will become apparent from the detailed description below, in light of the accompanying drawings.
