DETAILED DESCRIPTION
Provided is an audio performance system that can be easily and rapidly converted from a transport configuration of a shipping container containing an electroacoustic device to a configuration in which the shipping container may be used as part of a performance or event, typically, but not necessarily attended by the public. Such a performance or event may occur as part of a performance of a professional entertainer, speaker, sporting event or other occasion. However, for purposes of the disclosure, any purpose or event associated with an audio transmission is contemplated, and the term performance or event may be used interchangeably.
FIG. 1 shows a perspective view of an audio performance system 10 including a shipping container 12 and a shipping container 14. In one embodiment, shipping containers 12, 14 are sized to be portable by commercial air, land or sea transportation apparatus. Shipping container 12 includes a first electroacoustic device 20, such as an audio speaker that is secured in a first position 22 to a lifting device 16. As shown in the figures, first electroacoustic device 20 shows a plurality, also referred to as an array of devices that may be arranged to deliver optimum audio performance for an event. In another embodiment, lifting device 16 may be secured to a single first electroacoustic device 20. For purposes of the disclosure, the term electroacoustic device may refer to one or more electroacoustic device(s). First position 22 of lifting device 16 is associated with the contents of the shipping container being secured for transport, i.e., the shipping container is in a transport mode. As further shown in FIG. 1, shipping container 14 is also in a transport mode, and contains a plurality of third electroacoustic devices 60, such as sub woofer audio speakers for use with an event. Shipping container 12 is converted to a performance mode by virtue of movement of first electroacoustic device 20 by lifting device 16 from first position 22 to second position 24 (FIG. 2). In other words, in performance mode, first electroacoustic device 20 is positioned to deliver optimum audio performance to an audience of an event.
As further shown in FIG. 1, lifting device 16 of shipping container 12 forms a first portion 18 of the shipping container. That is, lifting device 16 is a structural component forming a portion of shipping container 12. As further shown in FIG. 1, first portion 18 of lifting device 16 extends to opposed third portions 27 that each define an interconnected corner frame 52 including a horizontal corner frame member 54 and a vertical corner frame member 56. Securing ends of horizontal corner frame member 54 and vertical corner frame member 56 together, such as by welding, form a corner 55 of corner frame 52. One third portion 27 of the pair of third portions 27 is shown more clearly in FIGS. 3 and 4.
As shown in FIG. 1, shipping container 12 includes a second portion 26 that collectively defines a pair of opposed interconnected corner frames 28 separated by an interconnected frame 38. As further shown in FIG. 1, second portion 26 collectively extends along three of the four sides of a base 62 of shipping container 12. As more clearly shown in FIG. 3, which is an exploded perspective view of each of the opposed interconnected corner frames 28 and interconnected frame 38 with respect to base 62, each interconnected corner frame 28 includes a horizontal corner frame member 36 and a vertical corner frame member 30 that are secured together at their respective ends, such as by welding to form a corner 29. The end of each vertical corner frame member 30 opposite corner 29 defines a tapered end 32 (disassembled vertical corner frame members shown in FIG. 3) that is received in a socket 34 of base 62 of shipping container 12 (assembled vertical corner frame members 30 shown in FIG. 1).
As further shown in FIG. 3, corner frame 28 further includes a horizontal frame member 37 separated by and collectively secured to a pair of vertical frame members 78 and a stiffener 80, such as by welding. An angled frame member 82 is secured between vertical corner frame member 30 and horizontal frame member 37, such as by welding, providing additional structural rigidity and support to interconnected corner frame 28. As further shown in FIG. 3, interconnected frame 38 includes horizontal frame members 40 and vertical frame members 42 joined together, such as by welding. When the ends of opposed interconnected corner frames 28 and interconnected frame 38 are brought together along the periphery of base 62 with interconnected corner frame 52, the abutting ends of the frames collectively form a closed box structure that when secured together by a fastener, each define a fastened joint 44. In one embodiment, the fasteners are configured for manual disassembly, and in yet another embodiment are quick release fasteners, such as ball-lock fasteners. That is, an individual should easily be able to form fastened joints 44 without requiring a tool, i.e., not requiring additional leverage normally required by wrenches, levers, etc. In summary, upon disassembly of fastened joints 44, each of the opposed interconnected corner frames 28 and interconnected frame 38 may be quickly and easily manually removed from shipping container 12.
It is to be understood that the removal of the frames composing second portion 26 provide unobstructed visual access to three of the four sides of shipping container 12, using base 62 for purposes of positional orientation. In this arrangement, lifting device 16 would typically be positioned opposite an intended audience of an event in order to provide visual access and maximize audio performance of the electroacoustic devices.
As further shown in FIG. 2, once leveling legs 74 are set (removing weight from casters 72) lifting device 16 is actuated from a first position 22 (FIG. 1) typically associated with a transport mode of the shipping device, to a raised second position 24 that is associated with a performance mode as previously discussed. As shown in the figures, lifting device 16 includes a yoke 46 that is constrained to move vertically along first portion 18. That is, yoke 46 cannot rotate with respect to first portion 18. Yoke 46 is urged to move along first portion 18 between the first and second positions 22, 24 by a cable 48 (FIG. 1) powered by a motor (not shown). In another embodiment, cable 48 may be manually actuated. As further shown in FIG. 3, yoke 46 is moveably secured to first electroacoustic device 20 such that first electroacoustic device 20 is selectably rotatable about axis 47. In one embodiment, axis 47 is positioned in close proximity with the center of gravity of first electroacoustic device 20 for purposes of stability, although first electroacoustic device 20 may be rotated as required to provide optimum audio performance for an event. Adjustment of first electroacoustic device 20 includes an option of angular adjustment in predetermined increments, such as insertion of a pin or other device in one of a plurality of angularly spaced openings formed in yoke 46 surrounding axis 47, and/or an arcuate slot formed concentrically In yoke 46 with respect to axis 47 that permits a device, such as a threaded pin with a handle (not shown) to be secured to first electroacoustic device 20, permitting custom angular adjustment. In addition, the angular spacing between individual first electroacoustic devices 20 also include an amount of adjustment therebetween.
As shown in FIG. 4, shipping container 12 is arranged with first electroacoustic device 20 positioned in second position 24 (performance mode) with second portion 26 (FIG. 3) removed. FIG. 4 further shows the inclusion of a pair of third electroacoustic devices 60 supported on base 62 beneath first electroacoustic devices 20. In another embodiment, third electroacoustic devices 60 may be suspended from first electroacoustic devices 20. The pair of third electroacoustic devices 60 were previously secured in shipping container 14 (FIG. 2) in transport mode. As further shown in FIG. 4, a cover 76 extends between a supporting surface 84, such as the ground and base 62 to provide an aesthetically pleasing arrangement, as well as concealing casters 72 and a compartment 64 configured to secure a fourth electroacoustic device 66 (FIG. 1). In other words, cover 76 substantially prevents viewing of components contained beneath base 62, most notably fourth electroacoustic device 66.
As shown in FIG. 5, the shipping container arranged in performance mode as shown in FIG. 4 can further include a pair of second electroacoustic devices 50 secured by a yoke 58 that is rotatably secured in close proximity to corner 55 of third portion 27. Only one second electroacoustic device 50 is shown in FIG. 5.
As shown in FIG. 6, shipping container 12 while in transport mode can be configured for airborne movement as required. An air lifting assembly 68 can be secured to yoke 46 or other appropriate structurally robust portion of the shipping container prior to application of a vertical lifting force 70 that is applied to move the shipping container 12. In another embodiment, shipping container 14 while in transport mode can also be configured for airborne movement as required.
