FIG. 1A shows an embodiment of a platform system 101 including a module assembly 102. The module assembly 102 shown includes a receiving member 207 and a plurality of video modules 109 (enlarged in FIG. 1B). In one embodiment, the receiving member 207 engages one or more supports 103 (see also FIGS. 2 and 34). The supports 103 are elongate structures having a laterally stabilizing support structure 107 and an elongate portion 201 (for example, a cylindrical tube) (see also FIGS. 31 and 34).
In one embodiment, the platform system 101 is configured as a stage or platform for any suitable event, such as an entertainment or sporting event. Examples of events include, but are not limited to, concerts, dance exhibits, wrestling matches, or other performances, other examples of uses for the platform system 101 include, but are not limited to, media/announcer areas, concessions, ticket or merchandizing areas, or equipment supports. The platform system 101 is located in any suitable environment, such as, but not limited to, outdoors, exposed to ambient conditions, indoors, underwater, partially exposed, and combinations thereof. The platform system 101 is supported from underneath by any suitable underlying surface 414 (see FIGS. 34 and 35), such as, but not limited, to a hardwood floor, a carpeted floor, a concrete slab, a brick lot, a street, a sloped floor, an uneven floor, a dirt field, a grassy meadow, a flooded yard, and combinations thereof. In one embodiment, the platform system 101 is capable of being quickly and easily leveled when assembled on uneven or sloped surfaces or terrain, such as at outdoor venues.
Referring to FIGS. 34 and 35, in one embodiment, the platform system 101 for leveling a stage includes one or more module assemblies 102 and one or more supports 103. Each module assembly 102 includes one or more receiving members 207. The one or more supports 103 are engaged and removably secured to each of the one or more receiving members 207. Each support 103 includes an elongate portion 201, an extendible portion 202 extendible from and lockingly engageable with the elongate portion 201, a base member 400 removably attached to the extendible portion 202, and an actuator assembly 300 secured to the elongate portion 201 and in communication with the extendible portion 202. The actuator assembly 300 is configured to rapidly extend and lockingly engage the extendible portion 201 and the base member 400 to provide self-leveling of each of the one or more module assemblies 102 of the stage as the base member 400 engages an underlying surface 414.
Referring again to FIGS. 34 and 35, the support 103 includes a laterally stabilizing support structure 107 capable of connecting to a laterally stabilizing support 105. In one embodiment, the platform system 101 includes one or more walkout ramps 118 similar to a runway or catwalk, configured so a performer can move closer to the audience. The one or more walkout ramps 118 is operative to connect to a main platform system 108. In one embodiment, the main platform system 108 includes four or more rows and four or more columns of adjacently connected module assemblies 102 (as per the platform system 101 in FIG. 1A, for example). In one embodiment, the width the one or more walkout ramps 118 is less than the width of the main platform system 108 at the side where the connection is made (not shown). In one embodiment, the walkout ramp 118 includes one or more series of rows of from one to four adjacent module assemblies 102 connected to the main platform system 108 (not shown). The number of adjacent module assemblies 102 in the walkout ramp 118 varies as is desired by the application. In one embodiment, the module assembly 102 includes an adaptor connector system 120 that enables adjacent module assemblies 102 to be connected together at an angle relative to their horizontal planes (see FIG. 34).
The one or more module assemblies 102 of platform system 101 are self-leveled against an uneven underlying surface 414 by varying the length of the supports 103. In one embodiment, varying the length of the supports 103 positions the module assemblies 102 at a predetermined approximately level horizontal elevation (see FIG. 35). In one embodiment, varying the length of the supports 103 positions the module assemblies 102 of the main platform system 108 at a predetermined approximately level horizontal elevation, and positions the walkout ramp 118 at a predetermined slope relative to the main platform system 108 (see FIG. 34).
Referring to FIGS. 31-33, the elongate portion 201 includes a first end 204 having a tapered portion 229, and a second end 206. The extendible portion 202 is operable to extend from and lockingly engage the second end 206 of the elongate portion 201. In one embodiment, the extendible portion 202 is configured to be telescoping, or to slide within the elongate portion 201. The extendible portion 202 includes a first end 208 and a second end 210. The first end 208 of the extendible portion 202 includes any suitable stop feature, such as a perimeter flange (not shown), for example, to prevent the extendible portion 202 from becoming totally disconnected from the elongate portion 201 during extension of the extendible portion 202.
As shown best in FIG. 32, the actuator assembly 300 is secured to the elongate portion 201 and in communication with the extendible portion 202. The actuator assembly 300 is configured to rapidly extend and lockingly engage the extendible portion 202 and the base member 400 to provide self-leveling of each of the one or more module assemblies 102 of the platform system 101 as the base member 400 engages an underlying surface 414.
Referring to FIG. 32, the actuator assembly 300 includes a housing 302, an actuator 304, and a biasing device 306 arranged and disposed within the housing 302. The biasing device 306 is in communication with the actuator 304. In one embodiment, the actuator 304 is configured such that at least a portion of the actuator 304 is slideable down within the housing 302 upon activation by the application of force. A suitable example of activation by force includes, but is not limited to, a push button. In one embodiment, the actuator 304 is configured to slide along an axis that forms an angle 305 with a longitudinal axis 303 of the extendible portion 202. The angle 305 is from about 14 degrees to about 34 degrees, or alternatively from about 17 degrees to about 31 degrees, or alternatively from about 20 degrees to about 28 degrees. In one embodiment, the biasing device 306 is any suitable biasing device, such as, but not limited to, a spring, configured to bias the actuator 304 into a locked position. The locked position is a position operating to lockingly secure the extendible portion 202 of the support 103 and prevent movement of the extendible portion 202 within the elongate portion 201 of the support 103. In the locked position, the extendible portion 202 does not move within the elongate portion 201. The locked position prevents the extendible portion 202 from extending from or retracting within the elongate portion 201.
As shown in FIGS. 32 and 32A, the actuator 304 includes a retention system 308 configured to engage and lockingly secure the extendible portion 202. The retention system 308 is any suitable system configured to lockingly engage the extendible portion 202 in a locked position, and disengage the extendible portion 202 upon activation of the actuator 304. In one embodiment, activation of the actuator 304 is by a pressure or force applied, pushing downward on the upper surface of the actuator 304, causing it to slide down into the housing 302. The actuator 304 is generally configured to be operated by any suitable force transferring device, such as, but not limited to a user's hand, foot, or by a tool, or other suitable device. One example of applying pressure or force, includes, but is not limited to, an operator stepping down on the upper surface of the actuator 304.
As shown in FIGS. 32 and 32A, the retention system 308 includes any suitable arrangement of one or more protrusions, recesses, and combinations thereof, configured for engaging with the extendible portion 202. In one embodiment, one or more of the one or more protrusions, recesses, and combinations thereof, include an angled surface 309. The angled surface 309 of the one or more protrusions, recesses, and combinations thereof, forms an angle 307 with a traverse plane 311 of the extendible portion 202, and the angle 307 of the one or more protrusions, recesses, and combinations thereof, is approximately equal to the angle 305 of the actuator. In one embodiment, the one or more protrusions, recesses, and combinations thereof have a suitable curved geometry, such as, but not limited to, concave geometry, relative to the longitudinal axis 303 of the extendible portion 202. In one embodiment, the concave geometry of the protrusions, recesses, and combinations thereof, is approximately equal to, or matches the perimeter curvature of the extendible portion 202 relative to the longitudinal axis 303 of the extendible portion 202.
Referring again to FIGS. 32 and 32A, in one embodiment, the extendible portion 202 includes a reception system 205 operable to engage the actuator 304. The reception system 205 includes any suitable arrangement of longitudinally spaced openings, recesses, protrusions, and combinations thereof, on an exterior surface of the extendible portion 202, such as, but not limited to, a straight threaded surface. The reception system 205 is configured to cooperate with and engage the retention system 308 of the actuator 304, thereby locking the extendible portion 202 of the support 103 in the locked position. In one embodiment, one or more of the spaced openings, recesses, protrusions, and combinations thereof, include an angled surface 310. The angled surface 310 of the one or more of the spaced openings, recesses, protrusions, and combinations thereof, also forms the angle 307 with the traverse plane 311 of the extendible portion 202. In one embodiment, the one or more protrusions, recesses, and combinations thereof of reception system 205 and the one or more protrusions, recesses, and combinations thereof of the retention system 308 are configured with suitable cooperating and mating geometries, such as, but not limited to gear teeth, so as to mesh during engagement. In one embodiment, during engagement, the angled surfaces 309 of the retention system 308 engage at least a portion of the angled surfaces 310 of the reception system 205.
In one embodiment, activating the actuator 304 disengages the retention system 308 from the reception system 205 (see FIG. 31). Activating the actuator 304 operates to slide and move the actuator 304 inside the housing 302 at angle 305, thereby disengaging the one or more of the spaced openings, recesses, protrusions, and combinations thereof, of the of reception system 205 and the one or more protrusions, recesses, and combinations thereof, of the retention system 308. Activating the actuator 304 by continued application of force or pressure continues to keep the retention system 308 disengaged from the extendible portion 202, thereby allowing the extendible portion 202 to slide freely within the elongate portion 201. Activating the actuator 304 and disengaging the retention system 308 releases the extendible portion 202, allowing gravity to extend the extendible portion 202 downward to engage the underlying surface 414. This automatic extension of the extendible portion 202 results in self-leveling of the one or more module assemblies 102. In an alternative embodiment, activating the actuator 304 releases the extendible portion 202, and the extendible portion 202 is manually extended or retracted into position. In one embodiment, releasing the pressure or force from the actuator 304 acts to re-engage the retention system 308 with the reception system 205 of the extendible portion 202, thereby locking the extendible portion 202 back into place into the locking position. The reception system 205 is configured to allow the extendible portion 202 to be positioned and locked to provide various lengths for the support 103 as required during assembly of the platform system 101. The variable lengths of the support 103 allow for self-leveling of the platform system 101 when the underlying surface 414 is uneven (see FIGS. 34 and 35). Once the platform system 101 is self-leveled, the actuators 304 maintain the supports 103 in a locked, self-leveled position. In one embodiment, the actuator assembly 300 includes a safety lock device (not shown) that operates to secure the actuator 304 in the locked position. The safety lock device operates to keep the extendible portion 202 in the locked, self-leveled position to guard against accidental activation of the actuator 304.
Referring to FIG. 32 again, the base member 400 is removably attached to the second end 210 of the extendible portion 202. In one embodiment, the base member 400 includes a center member 406 with a first end 402 and a foot 408 arranged and disposed at a second end 404. In one embodiment, the first end 402 includes any suitable pivot device or feature, such as, but not limited to, a ball joint 410. The pivot device or feature is operable to rotate the base member 400 relative to the longitudinal axis 303 of the extendible portion 202. In one embodiment, the second end 210 of the extendible portion 202 is configured to engage and cooperate with the ball joint 410 or other pivot feature.
In one embodiment, the foot 408 includes a substantially planar surface 412 for engaging an underlying surface 414 such as a floor or an outdoor field (see FIGS. 34 and 35). In one embodiment, the planar surface 412 includes gripping or projecting features (not shown) that operate to improve contact and engagement with the underlying surface 414, and to prevent sliding and/or slippage of the foot 408 once engaged (not shown). In one embodiment, as the planar surface 412 engages the underlying surface 414, the base member 400 rotates relative to the extendible portion 202, positioning the base member 400 substantially perpendicular to the underlying surface 414.
As shown in FIG. 32, the extendible portion 202 includes one or more handles 602 arranged and disposed at the second end 210, and extending therefrom. In one embodiment, two handles 602 extend each from opposing sides of the extendible portion 202, connecting substantially perpendicular to the vertical centerline of the extendible portion 202. In one embodiment, the handles 602 have angled portions 604 that extend upwards toward the first end 208 of the extendible portion 202. The handles 602 are configured to assist the user in retracting the extendible portion 202 back into the elongate portion 201. As shown in FIG. 32, the extendible portion 202 is capable of being retracted substantially fully back into the elongate portion 201, and lockingly engaged, to allow for a storage position, and ease of transport of the support 103.
As shown in FIG. 37, in one embodiment, a method 1000 of assembling a platform system 101 is provided. The method 1000 includes providing one or more module assemblies 102 including one or more receiving members 207 (step 1002, see FIG. 1A), and providing one or more supports 103 (step 1004, see FIGS. 34 and 35). As shown in FIG. 31, the supports 103 include an elongate portion 201 including a first end 204 and a second end 206, an extendible portion 202 operable to extend from and lockingly engage the second end 206 of the elongate portion 201, a base member 400 removably attached to the extendible portion 202, and an actuator assembly 300 secured to the elongate portion 201 and in communication with the extendible portion 202. The method 1000 includes positioning the module assembly 102 above or on the desired location on the underlying surface 414 (step 1006, see FIGS. 34 and 35). The method 1000 includes securing the one or more supports 103 to the one or more receiving members 207 (step 1008, see FIGS. 34 and 35). The method 1000 includes actuating the actuator assembly 300 (step 1010, see FIG. 31). Actuating the actuator assembly 300 extends the extendible portion 202 until the base member 400 engages an underlying surface 414 (see FIGS. 34 and 35). The base member 400 provides self-leveling of each of the one or more module assemblies 102 secured to the one or more supports 103. The method 1000 includes locking the extendible portion 202 to secure the one or more supports 103 in an extended and leveled position (step 1012, see FIGS. 34 and 35). In one embodiment, the method 1000 of assembling platform system 101 includes providing the main platform system 108 and one or more of the walkout ramps 118, and further connecting the one or more walkout ramps 118 to the main platform system 108. In one embodiment, the method 1000 further includes retracting the extendible portion 202 back into the elongate portion 201, and lockingly engaging the elongate portion 201 into a storage position for ease of disassembly and transport.
In an alternative embodiment, the method of assembling a platform system 101 (for example, see the platform system 101 of FIGS. 34 and 35) includes predetermining the approximate desired length of the one or more supports 103 to be used with a given module assembly 102. In one embodiment, the method of assembling a platform system 101 includes pre-extending the extendible portions 202 of the supports 103 until they reach the approximate desired length. The method includes securing the one or more supports 103 to the one or more receiving members 207, and positioning the module assembly 102 above or on the desired location on the underlying surface 414. In one embodiment, the alternative method of assembling platform system 101 includes providing the main platform system 108 and one or more of the walkout ramps 118, and further connecting the one or more walkout ramps 118 to the main platform system 108. The method includes actuating the actuator assembly 300 to level the module assembly 102 in a predetermined position relative to and against an uneven or sloped surface, thereby providing self-leveling of the module assembly 102. In one embodiment, the actuating the actuator assembly 300 extends or retracts the extendible portion 202 until the base member 400 engages a surface, providing self-leveling of each of the one or more module assemblies 102 secured to the one or more supports 103. The method includes locking the extendible portion 202 to secure the one or more supports 103 in an extended position, and in the locked and self-leveling position. In one embodiment, the actuator assembly 300 is re-actuated to either extend or retract the extendible portion 202 to account for variations in the load applied to the module assembly 102 or to account for settling or shifting of the underlying surface 414.
Referring to FIG. 20, in one embodiment, the platform system 101 includes the module assembly 102 with the video module 109 being removably secured to and supported by the receiving member 207. The module assembly 102 is configured to secure at least one video module 109. In one embodiment, the module assembly 102 is configured to secure the plurality of the video modules 109, for example, a fourth video module 109d and a fifth video module 109e. In further embodiments, the module assembly 102 is configured to secure three video modules 109, four video modules 109, or more. In one embodiment, the module assembly 102 is modular and is configured for use with any type of panel module capable of supporting a predetermined structural load. For example, in one embodiment, one or more of the plurality of the video modules 109 is temporarily or permanently replaced with a non-video module or a non-video module is otherwise included. Suitable non-video modules include, but are not limited to, mirrors, opaque modules, wood modules, grating, polymeric modules, trap door modules, elevator modules, pyrotechnic chambers, modules housing chambers (for example, with water, inside), or combinations thereof.
In one embodiment, the module assembly 102 includes a connector 702. The connector 702 secures the video modules 109 and/or the module assembly 102. The connector 702 provides support and stability, for example, by providing constant force, for example, by clamping, drawing, or otherwise providing force to urge the video modules 109 and/or the module assemblies 102 together. For example, as shown in FIG. 14B, in one embodiment, the connector 702 includes a rotatable latch member 111 and/or a receiving mechanism 112, thereby providing stable, locked engagement. In one embodiment, as shown in FIGS. 24 and 25, the connector 702 is or includes a latch connector. In one embodiment, as shown in FIGS. 26 and 27, the connector 702 is or includes a coffin lock connector. In one embodiment, as shown in FIGS. 28 and 29, the connector 702 is or includes a spline connector.
Referring to FIGS. 21A-B and 22, in one embodiment, the video module 109 includes a contoured video panel 706. The contoured video panel 706 includes a support portion 710 and a perimeter 714 extending around the support portion 710. During assembly of the platform system 101, the contoured video panel 706 is installed in the module assembly 102 such that one or more sides of the perimeter 714 engage or abut the module assembly 102.
The video module 109 includes an array of light emitting devices 720 (see also FIGS. 21A and 21B). The receiving member 207 is configured to directly or indirectly detachably secure a plurality of the video modules 109. For example, as shown in FIG. 1A, in one embodiment, receiving member 207 directly secures a first video module 109a to a second video module 109b and/or indirectly secures a third video module 109c to the first video module 109a and/or the second video module 109b. As will be appreciated, in other embodiments, any number of the video modules 109 are capable of being secured by the receiving members 207.

The hook member 221 allows for at least one laterally stabilizing support 105 to be attached to the support 103, allowing increased stability for the platform system 101 (see FIG. 1A).
Referring to FIG. 1A, in one embodiment, the laterally stabilizing support 105 is attached to the laterally stabilizing support structure 107 and to another structure. For example, the other structure is a fitting on the module assembly 102 of the stage or platform system 101, another laterally stabilizing support structure 107 on another support 103, a fitting on another support 103, or a fitting on an additional support. In one embodiment, the laterally stabilizing supports 105 are engaged and secured by the support locks 744 (see support locks in FIG. 23). In one embodiment, the laterally stabilizing support structures 107 are located at ninety degrees, circumferentially, on the support 103 (see FIG. 12). In one embodiment, the laterally stabilizing supports 105 for the internal supports 103 are attached to four laterally stabilizing supports 105 radiating from the support 103. In one embodiment, there are two laterally stabilizing supports 105 on the supports 103 located on the corner of the platform system 101. In one embodiment, there are two laterally stabilizing supports 105 on the supports 103 that are on the outside perimeter of the platform system 101. This configuration of the laterally stabilizing supports 105 permits stability with a minimal amount of obstruction. Nonetheless, any or all of the laterally stabilizing supports 105 are capable of being removed.
FIG. 12 shows the laterally stabilizing support structure 107 including a plurality of hook portions 221. The hook portions 221 extend from a laterally stabilizing support structure attachment portion 901. The laterally stabilizing support structure attachment portion 901 includes a geometry that is suitable for attachment to the support 103. The attachment portion 901 embodiment shown in FIG. 12 includes a pair of clamp-like structures that are fastened together by fasteners 903. The attachment portion 901 includes an attachment surface 909 that attaches to the support 103 (see FIG. 2) upon sufficient engagement of fasteners 903 to draw the attachment surfaces 909 into compressive contact with the support 103. In one embodiment, the compressive contact is achieved with a connector of fastener that constantly provides an inward force. The attachment portion 901 is not limited to the geometry shown in FIG. 12. For example, in one embodiment, the attachment 901 includes a geometry that permits the attachment of the laterally stabilizing support structure 107 to the support 103. In one embodiment, the attachment of the laterally stabilizing support structure 107 to the support 103 takes place using any suitable method, including frictional attachment provided by fasteners 903, adhesive, thermal shrink fit, welding or providing a unitary support 103 having the structure of the laterally stabilizing support structure 107 integrally included. Although FIG. 12 shows four hook portions 221. In other embodiments, the laterally stabilizing support structure 107 includes any number of hook portions 221 and includes a hook portion 221 for each elongate portion 103 that is in locking engagement with the laterally stabilizing support structure 107. Additionally, in one embodiment, the laterally stabilizing support structures 107 is fabricated with a symmetrical arrangement of hook portions 221, such as the four hook portions 221 shown in FIG. 12, for ease of assembly and alignment of the support 103 when the platform system 101 is assembled. In one embodiment, the hook portions 221 include a curved portion 905 that has a radius of curvature that allows a laterally stabilizing support connector 1301 of a laterally stabilizing support 105 (see FIGS. 13A and 13B) to be directed over the hook portion 221. The curved portion includes an engagement surface 907 that is capable of engaging the laterally stabilizing support connector 1301 and reacting to forces transmitted through the laterally stabilizing support 105. When the laterally stabilizing support connector 1301 is in position and in engagement with the engagement surface 907, the curved portion 905 locks the laterally stabilizing support connector 1301 in place and prevents disengagement, thereby retaining the laterally stabilizing support 105 in locking engagement.
FIGS. 13A and 13B illustrate two orthogonal views of the laterally stabilizing support 105 according to an embodiment of the invention. In one embodiment, the laterally stabilizing support 105 includes the elongate portion 100 having a substantially cylindrical geometry, and two laterally stabilizing support connectors 1301, disposed, one at each opposing end. In one embodiment, the laterally stabilizing support 105 includes any suitable geometry capable of transferring force from the module assembly 102 to the supports 103 when the platform system 101 is assembled (see FIG. 1A). As discussed above with respect to FIG. 1A, in one embodiment, the laterally stabilizing support connectors 1301 include any structure, such as eyelets, for example, that is suitable for engaging the module assembly 102 and the laterally stabilizing support structure 107 on the support 103. The laterally stabilizing support structure at each end of the laterally stabilizing support 105 are the same configuration, or the laterally stabilizing support connector 1301 connectors have different configurations from each other. In addition, the laterally stabilizing support connector 1301 is capable of being configured in any suitable geometry that includes one end that is capable of detachably engaging the module assembly 102 and one end that is capable of being in locking engagement to the laterally stabilizing support structure 107.
FIGS. 10 and 11 show additional support structure to attach to or otherwise engage module assembly 102. The additional support corresponds to the structures selected from the group consisting of a longitudinal casing attachment 500, a latitudinal casing attachment 502, and any combinations thereof. The longitudinal casing attachment 500 (see FIG. 10) includes the casing attachment panel 505, which in one embodiment is the magnetic panel 227, as shown and described above in FIG. 3, and the alternative support slot 507. The latitudinal casing attachment 502 (see FIG. 11) includes the casing attachment panel 505 and the alternative support slot 507. In one embodiment, the casing attachment panel 505 includes several screws for attaching the casing attachment panel 505 to the casing 225; however, the casing attachment panel 505 is capable of being attached to the casing 225 by using the magnetic panels 227, an adhesive, welding, or any other suitable method of attachment. The support slots 507 receive module assembly 102 and are supported thereby. The width and height of the additional supports is capable of being modified to fit specific needs of the platform system 101. The longitudinal casing attachment 500 has a narrower width and a taller height. The latitudinal casing attachment 502 has a wider width and a shorter height. The longitudinal casing attachment 500 and the latitudinal casing attachment 502 further include a panel support area 509, which is arranged to receive the video module 109, when the platform system 101 is assembled. In one embodiment, the casing 225 works in conjunction with both the longitudinal casing attachment 500 and the latitudinal casing attachment 502. The alternative support slot 507 has any geometry configured to the additional support. In one embodiment, the alternative support slot 507 includes a rectangular opening permitting a wood plank to be inserted into the alternative support slot 507 as the additional support; however, the additional support can be made of any material sufficient to provide the necessary support.
Referring again to FIG. 1A, in one embodiment, the platform system 101 includes wheels 106, which provide contact with the underlying surface 414 of the platform system 101. In one embodiment, the support plates 742 are configured for attachment of the wheels 106 to the platform system 101. Although wheels 106 are shown, other structures may be utilized including, but not limited to, rollers, fixed feet, rotating feet 412 (see FIG. 34), stakes, posts, or other structures suitable for engaging the surface underlying the platform system 101. As shown in the multilevel portion 110, the wheels 106 are attached to the video modules 109 and/or module assembly 102 to permit rolling or moving of the platform system 101, even after assembly. Likewise, the single level portion 113 includes footing structures 104 having wheels that are attached to the support 103 and permit rolling or moving of the platform system 101, even after assembly. In another embodiment, the footing structures 104 are substituted with a stabilizing device. In one embodiment, the stabilizing device is a device formed of a solid substance (such as concrete, plastic, or other solids that can be worked with in liquid form), a mechanical system providing shock absorption, or other systems sufficient to provide stability for the support 103 and/or module assembly 102.
In one embodiment, the receiving members 207 are configured in the module assembly 102 to permit engagement with supports 103 from either the top surface or from the bottom to permit stacking of platform levels. That is, supports are mated to the receiving member 207 from two directions, permitting the formation of multiple levels. Although the multilevel portion 110 is shown as two platform levels, any number of additional levels are capable of being formed. In addition, the distance between platform levels is capable of being varied by providing supports 103 of varying lengths on each level.
Referring again to FIG. 1A, in one embodiment, the receiving members 207 are configured to engage with additional staging structures desirable for staging or platform use. For example, in one embodiment, as shown in FIG. 1A, additional staging structures, such as the stairs 115, engaged to the platform system 101 by insertion of a portion thereof into receiving members 207. The receiving members can also engage other staging structures, such as a runway ramp, for example, similar to the walkout ramp 118 (see FIG. 34). Likewise, in another embodiment, the railings 117 are inserted into the receiving members 207. The engagement includes any suitable engagement into receiving member 207, including, but not limited to gravity, interlocking, latching or magnetic attraction. In other embodiments, other staging structures are likewise be engaged to the platform system 101 by engagement with the receiving member 207.
In addition, the embodiment shown in FIG. 3 includes a second support 103′ extending from the receiving member 207. Although the embodiment shown includes a second support 103′, in other embodiments, the stairs 115, the railings 117 or other structures include the footing structure 104 configured to engage support cone 223 of receiving member 207 and engaged with the receiving member 207 (see FIG. 1A).
In one embodiment, the footing structure 104 on the support 103 includes a frusto-conical geometry or similar geometry. Tapered, frusto-conical, and conical geometry of the footing structure 104 on the support allow the support 103 to stand without additional support. This allows additional supports 103 to be positioned on the platform system 101. In one embodiment, once the supports 103 are all positioned and engaged, a second platform system 101 is positioned and engaged at the distal end of the receiving member 207 of the support 103. The second platform system 101 forms the second level for a multilevel portions of the platform system 101. In one embodiment, the process is repeated horizontally and/or vertically to produce a larger platform or stage on multiple levels. Tapered, frusto-conical, and conical geometry of the tapered portion 229 of the support 103 distribute the lateral forces allowing the platform system 101 to maintain stability, without swaying or bending, even when there are lateral forces present. In addition, the tapered, frusto-conical, and conical geometry help prevent misalignment of the support 103 by providing an engagement surface. Also, the support cone 223 aligns itself and allows workers having little or no technical skill to assemble the platform systems 101 quickly and easily. Disassembly is also easily achieved by reversing this process.
FIG. 16 shows the coupling member 301 as the footing structure 104, wherein the coupling member 301 includes an inner surface 504 and attaches to the elongate portion 201. FIG. 17 shows a coupling member 301 as the footing structure according to an alternate embodiment, wherein the coupling member 301 is configured to attach to the railing 117 or be configured to attach to the stairs 115 (see FIG. 1A). In one embodiment, the walkout ramp 118 (see FIG. 34) includes railing similar to the stairs 115 (not shown), and is configured to connect to the main platform system 108 with a module assembly 102 including coupling members 301 (not shown).
Referring to FIGS. 14A and 18, in one embodiment, the multilevel portion 110 includes the support 103 with the tapered portion 229 including the flange 215, a first taper 601 and a second barrel portion 603. The tapered portion 229 is attached to elongate portion 201. During assembly, as discussed above, the supports 103 are preferably positioned, unsupported on a level of video modules 109, module assemblies 102 and receiving members 207. By unsupported, it is meant that all of the support is provided by the engagement of the tapered portion 229 and the support cone 223. A receiving member 207 of an upper level of video modules 109, module assemblies 102 may be positioned over the tapered portion 229 and is permitted to engage.
Referring to FIG. 36, in an alternate embodiment, the first end 204 of support 103 includes an alignment member 213 with a flared end. In one embodiment, the receiving member 207 includes any suitable retention device (not shown), such as a ball detent assembly, for example, configured to engage the alignment member 213.
