Abstract
The described system provides a folding and self-contained truss based entertainment technology support system designed for rapid deployment. Embodiments disclose a system incorporating folding truss technology in conjunction with lighting, dimming, power and data distribution systems encompassing a complete and integrated mobile and rapid deployment lighting and lighting support system. Further embodiments describe truss systems used for the rapid deployment, installation and removal of entertainment systems including but not restricted to lighting, sound, video and scenic equipment.
Description
- This application claims the benefit of U.S. provisional patent application Ser. No. 61/018,714, filed Jan. 3, 2008, the entirety of which is herein incorporated by reference.
- Embodiments of the present invention generally relate to entertainment technology systems and in particular, to truss systems necessary to install and support entertainment systems including but not restricted to lighting, sound, video and scenic equipment in entertainment environments such as arenas, convention centers, hotel ballrooms, and theatres.
- Many of the entertainment truss support systems currently used in production applications are of a cumbersome and labor intensive nature, requiring the use of hand tools and skilled labor to assemble using conventional fasteners such as nuts and bolts or pins. Common configurations are the pinned box truss as illustrated in
FIG. 1 and the bolt together box truss as illustrated inFIG. 2 . In each case the truss is manufactured in short sectional lengths which are assembled on site to create a truss of the required length. The assembly method inFIG. 1 is accomplished by engaging a male spigot on the end of a first section of truss with female sockets on a second section of truss. A bolt is then passed through each of the engaged spigots and sockets and secured by a nut. These bolts securely connect the sections of truss into a single structural member. The assembly method utilized inFIG. 2 is a further commonly utilized method, incorporating 4 to 8 bolts, nuts and washers per truss joint. To assemble two sections the truss end plates are lined up, bolts are inserted in the aligned gusset plate holes and the nuts with washers are then applied and tightened. While this method has proven safe when executed properly, it inherently negates the strong point of the truss tubing itself by relegating the truss joints to relying on the strength of the bolts and gusset plates as opposed to using the tubing strength as in the method shown inFIG. 1 . The use of multiple bolts to connect truss sections is thus inefficient, less than ideal structurally, and time consuming to assemble. Further prior arts systems may use interleaving fingers, splines or other connection means as known in the art instead of the spigot and socket connection system shown herein; however all such systems require the connection of a plurality of separate truss sections to produce the required final truss. The systems described in U.S. Pat. No. 4,512,117 to Lange and illustrated in U.S. Pat. No. 4,392,187 to Bornhorst are typical of the art. - In prior art entertainment truss support systems, multiple sections of tube truss of varying dimensions and in lengths which commonly range from 1 ft to 10 ft as illustrated in
FIGS. 1 and 2 , are hand carried to the floor below the point where they are intended to be suspended. Then, as described above, they are sited end to end and hand bolted or pinned together to form the desired continuous length. This procedure requires access to available floor space immediately underneath the suspension points equal to or greater than the final assembled truss length and width. Once assembled, the finished truss is then suspended from chain-hoists or other lifting mechanisms well known in the art and raised to a working height convenient for the operators of approximately 4 to 5 ft. When secured at this operating height, entertainment technology equipment such as lighting, sound, video or scenery may be individually hung and installed in or from the truss. After installation of the entertainment technology equipment, power and data cables necessary for the operation of the entertainment technology equipment can be run on or through the truss, connected to the entertainment technology equipment, secured to the truss and finally run off the ends of the truss to their respective destinations for control and power. As a final step the hoists are then operated to raise the truss assembly with all the entertainment technology equipment and cabling attached to its desired operating height. - This assembly process is extremely labor intensive and resource consuming. The process requires skilled technicians at all stages including connecting and securing the trusses, rigging the entertainment technology equipment, and installing and securing the power and data cables. A fault in any of these areas such as an incorrectly tightened fastener or badly secured cable could create a potential safety hazard. Further, because of the need to use the entire space beneath the final truss hang position, which can mean utilizing the entire stage area, the technicians are often under severe time constraints and pressure to vacate that space in order to make it available to other crafts, such as scenic construction, sound, video and other technical components of an entertainment event. Continuous expert and knowledgeable supervision of the entire process is necessary to maintain a safe working environment.
- Further, if the floor space beneath the final rigging position is inaccessible for some reason, such as being over a seating area or pre-existing scenery or staging, then rigging prior art truss can be difficult if not impossible to achieve. In such cases the truss may need to be assembled elsewhere on site and is then manhandled into position in a difficult and potentially dangerous manner.
- Attempts have been made to improve these systems by transporting the truss sections with their entertainment technology equipment pre-installed such that they can drop down or otherwise fold into their operating positions as shown in
FIG. 3 andFIG. 4 . Such systems may be referred to as ‘pre-rig truss’ or ‘drop-truss’ and an example of such a system is disclosed in U.S. Pat. No. 4,862,336 to Richardson et al. Notwithstanding the pre-rigged improvements, these trussing systems are still assembled on site from individual, separate sections of truss and therefore require access to clear floor space immediately underneath the suspension points equal to or greater than the final assembled truss length. Assembly is done through the means discussed and skilled labor. -
FIG. 4 illustrates a ‘drop truss’ or ‘swing wing’ prior art assembly which incorporates folding sides to the truss sections. Such a system may be partially pre-installed with entertainment technology equipment and associated cabling, however the cable systems are again specific to each individual section of truss and need to be physically joined to adjacent sections during installation. The prior art systems solve neither the problem of floor space requirement nor do they provide improvements to the means of connection of the separate truss sections and associated cabling systems. - Therefore, there exists a need in the art for an improved method and system of installation of truss, entertainment technology equipment, and their power and control in entertainment technology applications that can be completed in a more timely and safe manner and within a reduced floor space.

- Embodiments of the present invention generally relate to entertainment technology systems and, in particular, to truss systems necessary to install and support entertainment systems including but not restricted to lighting, sound, video and scenic equipment in entertainment environments such as arenas, convention centers, hotel ballrooms, and theatres.
- The disclosed invention provides a structure and method to facilitate the rapid deployment and removal of an entertainment technology truss system designed to support entertainment technology equipment such as luminaires, dimmers, power distribution systems, loudspeakers, microphones, projectors, scenery or other entertainment technology equipment as well known in the art.
- In one exemplary embodiment of the invention as illustrated in
FIG. 5 , the entertainment technology equipment may be a plurality ofluminaires 110, dimmingsystems power distribution 114 along with all cabling to interconnect these devices.FIG. 5 illustrates anentire truss system 100 in a partially unfolded state so that the individual components are easier to distinguish. Five sections oftruss entertainment technology equipment truss sections truss sections truss sections hinges truss section 124first hinge 152 connecting totruss section 122 is on the bottom corner oftruss 124 whilesecond hinge 154 connecting totruss section 126 is on the top corner oftruss 124. - The use of hinges to connect the truss sections provides a permanent connection between the truss sections and further allows a dedicated path for cabling to be installed to connect the items of entertainment technology equipment with both electrical power and control data. This cabling may be permanently installed within the truss system and provide links and connections between all sections of truss. As the cabling runs between truss sections it is routed adjacent to the hinges such that it does not interfere with the operation of said hinges and so that no strain or load is placed on the cabling. In the illustrated embodiment such cabling may connect together the
power distribution unit 114, dimmingsystems luminaires 110 such that external connections tosystem 100 may be limited to a power supply cable and a data control cable. -
Truss system 100 may be fitted with wheels orcasters 104 such that it is easily moved around a venue or on and off vehicles for transport.Casters 104 may be fixed or removable and may be elevated or recessed. Each truss section may be fitted with a stop orbumper -
FIG. 6 illustrates an embodiment of thetruss system 100 in its folded, undeployed, state so that it may be stored and transported in the most compact configuration. The height and width of the folded system may be chosen so as to allow the system to pass through standard doorways and to be transported in standard vehicles. For example it may be constructed so as to be less than 8 ft in height so that it would easily be transported within a standard shipping container and pass through a typical loading dock door. The height and width of each truss section also may be selected so as to contain the required entertainment technology equipment within the structure of the truss section(s). - The truss system may be deployed in a number of manners depending on the floor space and venue height available. Two methods will be described; however other installation techniques are possible and the techniques of installation are not a limitation of the invention. We first consider an installation technique for a venue where we have a limited floor space available, but sufficient height. To deploy the truss system in these circumstances the folded
system 100 is positioned under a hoist suspension point and thefirst truss section 128 is connected to a hoist bysuspension line 116 as illustrated inFIG. 6 . The choice of suspension point and hoist is outside of the scope of this invention and such suspension points and hoists may be provided from chain hoists, counterweight systems, powered rigging hoists, manual winches or any other rigging suspension hoist as well known in the art.Suspension line 116 may then be raised such thatfirst truss section 128 is lifted and rotates aroundhinge 156 which connects it tosecond truss section 126 so as to raisefirst truss section 128 to a vertical position as shown inFIG. 7 .Suspension line 116 may then be lowered again such thatfirst truss section 128 continues to rotate abouthinge 156 and is lowered until it is axially aligned withsecond truss section 126 as illustrated inFIG. 8 .First truss section 128 andsecond truss section 126 may now be connected together atpoint 166 by use of a pin through the spigot, bolt, clamp or other method well known in the art such thatfirst truss section 126 andsecond truss section 128 are connected and behave as a single longer truss section and hinge 156 is constrained from rotation. -
Suspension line 116 may now be raised again and will liftfirst truss section 128 andsecond truss section 126 as a single combined unit to the vertical position illustrated inFIG. 9 . AsSuspension line 116 continues to lift it will start to raisethird truss section 124 which will rotate aroundhinge 152 until it also is vertical as shown inFIG. 10 .Second truss section 126 andthird truss section 124 may now be connected together atpoint 164 by use of a pin through the spigot, bolt, clamp or other method well known in the art such thatfirst truss section 126,second truss section 128 andthird truss section 124 are connected and behave as a single longer truss section and hinge 154 is constrained from rotation. - Similarly
suspension line 116 may now be further raised such thatfourth truss section 122 is also raised vertically and is secured atpoint 162 so that four sections are connected as shown inFIG. 11 . Finally,suspension line 116 may be further raised such thatfifth truss section 120 is also raised vertically and secured atpoint 160 so that all five truss sections are connected as shown inFIG. 12 and all hinges 150, 152, 154, 156 are constrained from further rotation. At this point asecond suspension line 118 may be connected to the truss system and the entire system raised and rotated as a single unit until it is horizontal in its final deployed orientation as illustrated inFIG. 13 . Although twosuspension points FIGS. 6 to 13 provides installation in a minimum of floor space in a very efficient and simple manner. At all times thetruss system 100 remains a single connected structure so that at no point are any truss sections separated from each other. The technicians have only to install theconnections - Although the methodology for five truss sections is disclosed in this embodiment the technique may be extended in further embodiments and any number of hinged truss sections may similarly be deployed and attached to one another, thus extending the overall truss length.
- In a further embodiment hinges 150, 152, 154, 156 may be provided with a locking mechanism through a pin, bolt, clamp or other device such that further security is provided to prevent rotation and movement at the hinge points.
- We now consider a second installation technique for a venue where we have sufficient floor space available to accommodate the entire length of the truss system but a low height. To deploy the truss system in these circumstances the folded
system 100 is positioned under a hoist suspension point and thefirst truss section 128 is connected to a hoist bysuspension line 116 as illustrated inFIG. 14 . The choice of suspension point and hoist is outside of the scope of this invention and such suspension points and hoists may be provided from chain hoists, counterweight systems, powered rigging hoists, manual winches or any other rigging suspension hoist as well known in the art.Suspension line 116 may then be raised such thatfirst truss section 128 is lifted and rotates aroundhinge 156 which connects it tosecond truss section 126 so as to raisefirst truss section 128 to a vertical position as shown inFIG. 15 .Suspension line 116 may then be lowered again such thatfirst truss section 128 continues to rotate abouthinge 156 and is lowered until it is axially aligned withsecond truss section 126 as illustrated inFIG. 16 . The unfolding truss stack, being on casters, rolls and stays directly under the lift point while it unfolds.First truss section 128 andsecond truss section 126 may now be connected together atpoint 166 by use of a pin, bolt, clamp or other method well known in the art such thatfirst truss section 126 andsecond truss section 128 are connected and behave as a single longer truss section and hinge 156 is constrained from rotation. - A
second suspension line 117 may now be connected tosecond truss section 126 andfirst suspension line 116 andsecond suspension line 117 raised together such thatfirst truss section 128 andsecond truss section 126 are raised andthird truss section 124 will be rotated to a vertical position aroundhinge 152 as shown inFIG. 17 .Suspension lines truss sections casters 104 such thatthird truss section 124 continues to rotate and lower until it is axially aligned with bothsecond truss section 126 andfourth truss section 122 as illustrated inFIG. 18 .Second truss section 126 andthird truss section 124 may now be connected together atpoint 164 andthird truss section 124 andfourth truss section 122 may be connected together atpoint 162. At this point the first, second, third and fourth truss sections are connected together and may be further raised as a single unit bysuspension lines FIG. 19 until thefifth truss section 120 is raised into a vertical position by rotating aroundhinge 150. - A
third suspension line 118 may now be connected tofifth truss section 120 which may subsequently be raised untilfifth truss section 120 is axially aligned withfourth truss section 122 and can be connected together atpoint 160 to form the final deployed system as illustrated inFIG. 20 . All five truss sections are securely connected and all hinges 150, 152, 154, 156 are constrained from further rotation. - Although three
suspension points FIGS. 14 to 20 provides installation in a minimum of ceiling height space in a very efficient and simple manner. At all times thetruss system 100 remains a single connected structure so that at no point are any truss sections separated from each other. The technicians have only to install theconnections - Although the methodology for five truss sections is disclosed in this embodiment the technique may be extended in further embodiments and any number of hinged truss sections may similarly be deployed and attached to one another, thus extending the overall truss length.
- In a yet further embodiment hinges 150, 152, 154, 156 may be provided with a locking mechanism through a pin, bolt, clamp or other device such that further security is provided to prevent rotation and movement at the hinge points when the truss system is deployed. Such locking mechanism may take the applied load and relieve the hinge of the loaded stress.
- In all embodiments described herein the entertainment technology items installed in the truss system such as a lighting system comprising luminaires, dimming system and power distribution may subsequently be connected to existing or temporary distribution systems in the venue so as to connect to main data and power distribution. This may, in some embodiments, be accomplished through a single connection for power and a single connection for data providing an extremely simple and rapid installation of the entire system.
-
FIG. 21 illustrates a perspective view of an embodiment of theinvention 200 showing the truss sections unfolding.FIG. 22 illustrates views of a yet further embodiment of thesystem 300 with entertainment technology devices installed within the truss sections. - The embodiments disclosed provide a means for entertainment technology rigging that is both rapid to deploy and remove, and provide a safe integrated system at all times. The truss may also be installed with a minimum of labor and installation time while causing a minimum of inconvenience to other users of the space.
- While the disclosure has been described with respect to a limited number of embodiments, those skilled in the art, having benefit of this disclosure, will appreciate that other embodiments may be devised which do not depart from the scope of the disclosure as disclosed herein. While the disclosure has been described in detail, it should be understood that various changes, substitutions and alterations can be made hereto without departing from the spirit and scope of the disclosure.
