The prior applications are hereby incorporated into this application by reference as if fully set forth herein.
BACKGROUND OF THE INVENTION
• 1. Field of the Invention
• The present invention relates to electronic sign displays, but more specifically pertains to a modular display system which favors portability by having a plurality of stackable electronic display panels incorporated as modules which are mutually and removably attached or secured to one another and to mounting structures for the support thereof.
• 2. Description of the Prior Art
• Prior art electronic sign displays can be of gigantic proportion and are fashioned utilizing large and heavy structure which requires heavy handling and positioning devices for installation. Ordinarily, the use of such equipment is not a concern where such electronic sign displays are installed on a one-time permanent basis in a concert hall, auditorium or at a stage setting. Entertainment venues of many sizes and varieties often require electronic sign displays in cooperation with entertainers, rock and roll performances, keynote speakers, bands, orchestras and the like where installation of such electronic sign displays is expensive and often cumbersome. Often the size or shape of electronic sign displays is another factor in that sometimes electronic sign displays are incompatible with doorways, halls and other structural and available space aspects of smaller or older entertainment venues. What is needed is an electronic sign display system which can be handled and simply erected by one person and which is of a suitable size and weight where accommodation and installation of the electronic sign display system in almost any size entertainment area, especially those having difficult access, is readily accomplished. Such a display system is provided by the present invention.

The LED displaymodule latching system52 is transversely located upon the rear of thesupport panel18 as shown inFIGS. 14 and 15 and is closely related to patent application Ser. No. 10/688,304 entitled “Electronic Display Module Having a Four-Point Latching System for Incorporation into an Electronic Sign and Process” filed Oct. 17, 2003. A portion of therear enclosure panel20 serves as a mount for accommodation ofsignal receptacles64 and66, apower receptacle68, and adiagnostic display70, all of which are shown inFIG. 3.
• The one-piece connector framework14 includes structurally reinforced and lightweight vertically aligned andopposed side panels72 and74 joined between the tops and bottoms thereof by horizontally aligned and opposed top andbottom channels76 and78 the structure of which serves to provide various types and styles of connection structure or for mounting of other connection structure thereto. Such structure includes, but shall not be limited to, configured connector plates, rearwardly located connector assemblies including connector plate receptors, slide pins and slide pin housings, forwardly located connector plate receptors and slide pins, as well as side latch assemblies having side latches, side latch keepers having an adjustable cam, a plurality of spring-loaded ball detents and corresponding detent holes, and other components for removable attachment and alignment of theconnector frameworks14, and thus theLED display modules16, along multiple axes and for juxtaposition of adjacent stackableelectronic display panels2a-2n,as later described in detail.
• A plurality of like alignment posts80 (FIG. 3) extend outwardly and rearwardly from thesupport panel18 to be accommodated in a corresponding plurality of alignment holes82 residing in the forwardly located planar faces84 and86 of theside panels72 and74, respectively, to aligningly locate and position the forwardly located planar faces84 and86 of theside panels72 and74 as well as the planar faces88 and90 of thetop channel76 and the bottom channel78 (i.e., the entire connector framework14) with and against the rearward facing region of thesupport panel18 of theLED display module16, such as is shown inFIG. 15. Theconnector frameworks14, each preferably of one-piece aluminum or, alternatively, of sturdy molded plastic having an anti-EMI coating, serve as alignable and sturdy structures for removable attachment of the stackableelectronic display panels2a-2n.In the alternative, certain other components could be fashioned of sturdy molded plastic and would require an anti-EMI coating for the suppression of EMI. Theconnector frameworks14 removably attach to one another to bring theLED display modules16 of each of the stackableelectronic display panels2a-2ninto closely aligned proximity to provide a substantially seamless display, as shown inFIG. 2.
• Also included as structure of theconnector framework14 are vertically orientedconnector plates92,94,96 and98 located at the tops of theside panels72 and74, eachconnector plate92,94,96 and98 having an arcuate top. Located at the bottoms of theside panels72 and74, respectively, are frontconnector plate receptors100 and102 and rearwardly locatedconnector assemblies104 and106.Connector assemblies104 and106 also include rearconnector plate receptors108 and110 andslide pin housings112 and114 (FIG. 3), respectively. Spring-loaded slide pins are associated with the frontconnector plate receptors100 and102 and the rearconnector plate receptors108 and110 for capture of theconnector plates92,94,96 and98, as described later in detail. A horizontally aligned handle/cable management bracket116 extends along and behind thetop channel76 and between the top regions of theside panels72 and74 and includes multi-purpose obliquely orientedslots118 and120. Theslots118 and120 can function as handholds, can also function as cable conduits, or can be used with attachment devices for maintaining orderly control of interconnecting cables between stackableelectronic display panels2a-2nor cables connecting the stackableelectronic display panels2a-2nto external devices, such as, but not limited to, computer control components.
• FIG. 5 is an exploded left rear view of aconnector framework14.FIG. 6 is an assembled left rear view of aconnector framework14.FIG. 7 is an assembled right rear view of aconnector framework14. With reference toFIGS. 5, 6 and7, singularly or in combination, or with reference to other figures, other components and features of the invention are now further described.
• Aligned attachment ofmultiple connector frameworks14 of the stackableelectronic display panels2a-2nalong the vertical aspect is accomplished by the use of components located at or near the intersections of theside panels72 and74 with the top andbottom channels76 and78, respectively, at the upper and lower regions of theside panels72 and74. More specifically, a vertically oriented front connectorplate mounting slot122 and a vertically oriented back connectorplate mounting slot124 are located at the upper end of theside panel72, and a vertically oriented front connectorplate mounting slot126 and a vertically oriented back connectorplate mounting slot128 are located at the upper end of theside panel74, each mounting slot having suitably located sets of threaded holes extending therethrough for securing of theconnector plates92,94,96 and98, respectively, thereto and therein, as shown later in detail. Theconnector plates92,94,96 and98 include engagement holes92a,94a,96aand98a,respectively, for subsequent engagement of spring-loaded slide pins, as described later in detail. At the lower region of theside panel72, the frontconnector plate receptor100 includes a vertically oriented front connectorplate receptor slot130, and at the lower region of theside panel74, the frontconnector plate receptor102 includes a vertically oriented front connectorplate receptor slot132. Attached to the lower region of theside panel72 is theconnector assembly104 having multiple structures including the rearconnector plate receptor108 which has a vertically oriented rear connectorplate receptor slot134. Attached to the lower region of theside panel74 is theconnector assembly106 having multiple structures including the rearconnector plate receptor110 which has a vertically oriented rear connectorplate receptor slot136. A front spring-loadedslide pin assembly138 is located in and aligns in structure at one end of thebottom channel78 in suitable alignment with the frontconnector plate receptor100 and front connectorplate receptor slot130, and a rear spring-loadedslide pin assembly140 is located in theslide pin housing112 in suitable alignment with the rearconnector plate receptor108 and rear connectorplate receptor slot134. Correspondingly, a front spring-loadedslide pin assembly142 is located in and aligns in structure at the other end of thebottom channel78, generally in suitable alignment with the frontconnector plate receptor102 and front connectorplate receptor slot132, as partially shown, and a rear spring-loadedslide pin assembly144 is located in theslide pin housing114 in suitable alignment with the rearconnector plate receptor110 and rear connectorplate receptor slot136. Connection of theconnector assemblies104 and106 to the lower structure of theside panels72 and74 includes adjustable features to provide for pivotal positioning of the lower end of theconnector framework14 and attached components forwardly or rearwardly about the “X” axis.Side latch assemblies146 and148 mount insegmented compartments150 and152 (FIG. 7), respectively, in theside panel72, and sidelatch keeper assemblies154 and156 mount insegmented compartments158 and160 (FIGS. 5 and 6), respectively, in theside panel74 to connect horizontally situatedconnector frameworks14 and to offer positioning of theconnector frameworks14 and attached components vertically along the “Y” axis, as later described in detail. Also located in and secured within the geometrically configured structure of theside panel72 are spring-loadedball detents162a,162band162c(FIG. 7) which assist in initial alignment of theside panel72 of oneconnector framework14 to detentholes164a,164band164c(FIG. 5) of theside panel74 of an adjacently locatedconnector framework14. With respect to vertically situatedconnector frameworks14, spring-loadedball detents166aand166bare located in and secured within the geometrically configured structure of thetop channel76 which assist in initial alignment of thetop channel76 of aconnector framework14 to detent holes (not shown) of thebottom channel78 of anotherconnector framework14 located thereabove. Threadedholes167 and169 are included at the rear of theside panel72 and threadedholes171 and173 are included at the rear of theside panel74 for mounting of the stackableelectronic display panels2a-2nto a mounting surface, as desired.
• FIGS. 8 and 9 are exploded left and right isometric views showing the junction of theside panel72 and thebottom channel78 of aconnector framework14 and the relationship of components attached to and utilized therewith. The structure and method of attachment of theconnector assembly104 allows for adjustable attachment to the lower region of theside panel72 using tongue and groove style geometry coupled with adjustable hardware to facilitate pivotal alignmental actuation of theconnector framework14 and associated components about the “X” axis. One lower portion of theside panel72 includes a horizontally orientedtongue168 which aligns to and which is adjustably actuated vertically within a horizontally orientedgroove170 at the top of theconnector assembly104. Mutual fixation of and actuation of theside panel72 with respect to theconnector assembly104 is facilitated by the use of a threadedshaft172, athumbwheel adjuster174, and other hardware and features. The threadedshaft172 extends through ahole176 in an extended portion of the lower region of theside panel72 and through a portion of thetongue168, and is affixed therein by anut178, preferably an acorn nut, at the top of the threadedshaft172 and anothernut180 in arecess182 located in close proximity to thetongue168. The lower portion of the threadedshaft172 extends through and below the general structure of thetongue168 to pass through a series of vertically aligned body holes184 located below thegroove170, through a threadedhole186 at the center of thethumbwheel adjuster174, and finally into the bottommost of the series of vertically aligned body holes184 being located in theconnector assembly104 at a position just below thethumbwheel adjuster174. An interruptedslot188 in horizontal orientation in theconnector assembly104 provides for locating of and rotational access to thethumbwheel adjuster174 and also provides opposed upper and lower bearing surfaces for intimate adjustmental contact with the upper and lower surfaces of thethumbwheel adjuster174. Thethumbwheel adjuster174, which is shown in place inFIG. 7, includes spacedholes189 about the periphery for accommodation of an adjustment tool. The interaction of thethumbwheel adjuster174 and threadedshaft172 with the interruptedslot188 provides for screw jack actuation of theconnector assembly104 with respect to theside panel72, whereby thetongue168 is actuated vertically with respect to thegroove170. More specifically, the interaction of thethumbwheel adjuster174 and threadedshaft172 provides for screw jack actuation of theconnector assembly104 with respect to theside panel72 about portions of the front spring-loadedslide pin assembly138. Correspondingly, another threadedshaft172, anothernut178, anothernut180, and anotherthumbwheel adjuster174 are provided and similarly utilized at the lower portion of theside panel74.
• The front spring-loadedslide pin assembly138 includes aslide pin190 having a taper at one end, anactuator shaft192 secured to and extending from theslide pin190, aknob194 at the outboard end of theactuator shaft192, apin196 extending through and beyond the circumference at opposing locations of theslide pin190, and aspring198 located about theslide pin190 and contained thereupon by thepin196 and structure described later in detail.
• Correspondingly as shown inFIG. 5, the front spring-loadedslide pin assembly142 includes aslide pin190ahaving a taper at one end, anactuator shaft192asecured to and extending from theslide pin190a,aknob194aat the outboard end of theactuator shaft192a,apin196aextending through and beyond the circumference at opposing locations of theslide pin190a,and aspring198alocated about theslide pin190aand contained thereupon by thepin196aand structure described later in detail.
• Structure in thebottom channel78 and structure in the frontconnector plate receptor100 functions as a mount and for interaction with the front spring-loadedslide pin assembly138 which is positionable therein to a closed or “engaged” position to lockingly and connectingly engage a connector plate, such asconnector plate92, of one of a vertically situated stackableelectronic display panel2a-2nlocated below. Such structure includes a vertically aligned inwardly locatedpanel200 vertically spanning the interior of thebottom channel78 having anarcuate surface202 exceeding 180° for accommodation of theslide pin190, and anaccess slot204 intersecting thearcuate surface202. Another structure is a vertically aligned outwardly locatedpanel206 vertically spanning the interior of thebottom channel78 having anarcuate surface208 and intersectingslot210, whereby the outwardly locatedpanel206 is incorporated for intimate contact with the inboard end of thespring198 and whereby thearcuate surface208 and theslot210 accommodate theslide pin190. Other structure includes aninboard hole212 extending through the inwardly located portion of the front connector plate receptor100 (FIG. 8) and anoutboard hole214 extending through the outwardly located portion of the front connector plate receptor100 (FIG. 9). Thearcuate surface202 and theinboard hole212 always provide support for theslide pin190 when the tapered end of theslide pin190 is retracted from the front connectorplate receptor slot130 toward the open or “disengaged” position. Theoutboard hole214 supplies full support for the tapered end of theslide pin190 when the tapered end of theslide pin190 is positioned just beyond the front connectorplate receptor slot130 in the “engaged” position. One end of thespring198 is contained on theslide pin190 by thepin196 and the other end of thespring198 is contained on theslide pin190 by impingement with the portion of the outwardly locatedpanel206 surrounding thearcuate surface208. Such capturing of thespring198 on theslide pin190 maintains outwardly directed force upon theslide pin190 to attempt to maintain theslide pin190 in the “engaged” position; i.e., the position utilized for engaged capture of a connector plate such asconnector plate92. During such an “engaged” position, a greater portion of theactuator shaft192 extending from theslide pin190 is positionally located between the inwardly locatedpanel200 and the outwardly locatedpanel206, and theslide pin190 is forcibly urged to maintain the “engaged” position by action of thespring198. Provision is made for positioning and maintaining the front spring-loadedslide pin assembly138 to the open or “disengaged” position so that unencumbered capture of a connector plate such asconnector plate92 can be easily and readily accomplished without interference. Such positioning is accomplished by ensuring that theactuator shaft192 has been maneuvered through theaccess slot204 which intersects thearcuate surface202 to a position inward of the inwardly locatedpanel200 and then toggling theactuator shaft192 either upwardly or downwardly and then releasing theknob194 to allow the action of thecompressed spring198 to force theactuator shaft192 to contact the inwardly locatedpanel200 to cause theslide pin190 to remain “disengaged” as positioned. Positioning of the front spring-loadedslide pin190 to the closed or “engaged” position is readily and easily accomplished by reorienting theactuator shaft192 to realign with theaccess slot204 to allow the force of thecompressed spring198 to forcibly urge the tapered end of theslide pin190 fully through the front connectorplate receptor slot130 and the frontconnector plate receptor100, as well as through anengagement hole92aof theconnector plate92 for suitable capture thereto. The front spring-loadedslide pin assembly142 functions in a similar and corresponding manner.
• The rear spring-loadedslide pin assembly140 is constructed and functions much in the same manner as the front spring-loadedslide pin assembly138. The rear spring-loadedslide pin assembly140 includes aslide pin216 having a taper at one end, anactuator shaft218 secured to and extending from theslide pin216, aknob220 at the outboard end of theactuator shaft218, apin222 extending through and beyond the circumference at opposing locations of theslide pin216, and aspring224 located about theslide pin216 and contained thereupon by thepin222 and structure described later in detail.
• The rear spring-loadedslide pin assembly144 shown inFIG. 5 includes aslide pin216ahaving a taper at one end, anactuator shaft218asecured to and extending from theslide pin216a,aknob220aat the outboard end of theactuator shaft218a,apin222aextending through and beyond the circumference at opposing locations of theslide pin216a,and aspring224alocated about theslide pin216aand contained thereupon by thepin222aand structure described later in detail. The rear spring-loadedslide pin assembly140 and the rear spring-loadedslide pin assembly144 function in a similar and corresponding manner.
• Theslide pin housing112 includes a vertically oriented inwardly locatedpanel226 having opposed upper and lowerarcuate surfaces228aand228b,afront access slot230 and arear access slot232, each intersecting the opposedarcuate surfaces228aand228b,and a vertically oriented firstintermediate panel234 having ahole236 extending therethrough. A vertically oriented secondintermediate panel238 being part of the rearconnector plate receptor108 and having ahole240 extending therethrough, and a vertically oriented outwardly locatedpanel242 being part of the rearconnector plate receptor108 and having anoutboard hole244 extending therethrough are incorporated for support of theslide pin216.
• Thearcuate surfaces228aand228band theholes236 and240 always provide support for theslide pin216 when theslide pin216 is retracted from the rear connectorplate receptor slot134. Theoutboard hole244 also supplies full support for the tapered end of theslide pin216 when the tapered end ofslide pin216 is positioned just beyond the rear connectorplate receptor slot134. One end of thespring224 is contained on theslide pin216 by thepin222 and the other end of thespring224 is contained on theslide pin216 by impingement with the portion of the firstintermediate panel234 surrounding thehole236. Such capturing of thespring224 on theslide pin216 maintains outwardly directed force upon theslide pin216 to attempt to maintain theslide pin216 in the “engaged” position; i.e., the position utilized for engagement of a connector plate such asconnector plate94. During such an “engaged” position, a greater portion of theactuator shaft218 extending from theslide pin216 is positionally located between the inwardly locatedpanel226 and the firstintermediate panel234, and theslide pin216 is forcibly urged to maintain the “engaged” position by action of thespring224. Provision is made for positioning and maintaining of the rear spring-loadedslide pin assembly140 to the open or “disengaged” position so that unencumbered capture of a connector plate, such asconnector plate94, can be easily and readily accomplished without interference. Such positioning is accomplished by ensuring that theactuator shaft218 has been maneuvered through either front orrear access slots230 or232 which intersect thearcuate surfaces228aand228bto a position inward of the inwardly locatedpanel226 and then toggling theactuator shaft218 either upwardly or downwardly and then releasing theknob194 to allow the action of thecompressed spring224 to force theactuator shaft218 to contact the inwardly locatedpanel226 to cause theslide pin216 to remain “disengaged” as positioned. Positioning of the rear spring-loadedslide pin assembly140 to the closed or “engaged” position is readily and easily accomplished by reorienting theactuator shaft218 to realign with either of the front orrear access slots230 or232 to allow the force of thecompressed spring224 to forcibly urge the tapered end ofslide pin216 fully through the outwardly locatedhole244 and the rearconnector plate receptor108 and through anengagement hole94aof theconnector plate94 for suitable capture thereto by incorporating the “engaged” position of theslide pin216. The front spring-loadedslide pin assembly142, the rear spring-loadedslide pin assembly144, and theconnector assembly106 are mirror image-like components of the front spring-loadedslide pin assembly138, the rear spring-loadedslide pin assembly140, and theconnector assembly104 having similarly constructed components in mirror image form having the same function and utilization.
• Side latch assemblies146 and148 mount insegmented compartments150 and152 (FIG. 7), respectively, in theside panel72, and sidelatch keeper assemblies154 and156 mount insegmented compartments158 and160 (FIGS. 5 and 6), respectively, in theside panel74 for mutual connection and interaction to connect horizontally situatedconnector frameworks14 and associated components and to offer positioning of theconnector frameworks14 and associated components vertically along the “Y” axis. Theside latch assemblies146 and148 are similar in construction having similarly designated components for use in either of thesegmented compartments150 or152. With reference toFIGS. 8 and 9,side latch assembly148 is now described. The lowerside latch assembly148 includes abracket246 suitable for mounting within thesegmented compartment152. An operatingshaft248 having a rearwardly facingtool receptor250 extends through the opposedsides252 and254 of thebracket246 for pivotal actuation therein. Alatch256, preferably having a hook shape, is located between thesides252 and254 and is attached over and about the operatingshaft248 and is positioned by the operatingshaft248 about the axis of the operatingshaft248. Additionally, anindicator tab258 secures to and extends inwardly from the rearwardly located portion of the operatingshaft248 for viewable accommodation by one of a number ofslots260 located in theside panel72.Individual indicator tabs258 are viewable through theslots260 whenindividual operating shafts248 each has been rotated to the position where thelatch256 engages a cam280 (FIG. 11) of an adjacent sidelatch keeper assembly154 to thereby verify the locked position of thelatches256. Each of thesegmented compartments150 and152 includes a notchedpanel262 for accommodation of the operatingshaft258, as well as opposedangled guide panels264 and266 extending in perpendicular fashion from theside panel72. Although theopposed guide panels264 and266 are shown as being planar, they can be of any suitable geometrical shape to offer tool guidance therebetween to align a suitable adjustment tool, such as a hex-head wrench for example, with thetool receptor250 of each of theside latch assemblies146 and148 installed within thesegmented compartments150 and152, such as generally shown inFIG. 10. A plurality ofaccess holes268 are located extending through theside panel72 for insertion of a suitable adjustment tool for actuation of theside latch assemblies146 and148.FIG. 10 shows theside latch assembly146 aligned in and secured within the angledsegmented compartment150 in the same fashion that theside latch assembly148 is aligned in and secured within thesegmented compartment152. Illustrated in particular is the alignment of thetool receptor250 in theside latch assembly146 with theguide panels264 and266 and theupper access hole268.
• FIG. 11 is a perspective view of the sidelatch receptor assembly154, andFIG. 12 is a side view of the sidelatch keeper assembly154. The sidelatch keeper assemblies154 and156 are similar in construction having similarly designated components for use in either of thesegmented compartments158 or160, as shown inFIG. 6. The sidelatch receptor assembly154 includes abracket270 having opposedsides272 and274. An operatingshaft276, part of which includes ahexagonal exterior278 and part of which is thecam280, extends through ahexagonal hole282 in theside272 and abody hole284 in theside274 of thebracket270, respectively, for pivotal actuation therein. A rearwardly facingtool receptor285 is included at one end of the operatingshaft276. Aspring clip286 engages one end of the operatingshaft276 adjacent to the outwardly located surface of theside274, and aspring288 aligns over and about one end of the operatingshaft276 between theside274 and anannular shoulder290 located at one end of thecam280 to spring load theoperating shaft276 in a direction outwardly from thebracket270. Such outwardly directed force causes a portion of thehexagonal exterior278 of the operatingshaft276 to lockingly engage thehexagonal hole282 in theside272 to maintain the last rotational orientation of thecam280. Agroove292 interrupts thehexagonal exterior278 of the operatingshaft276 at a location near thehexagonal hole282 to facilitate rotational adjustment of thecam280 for interaction with the side latch assembly, such asside latch assembly146 of one of the adjacent stackableelectronic display panels2a-2n,for vertical positional adjustment along the “Y” axis. Rotational adjustment of thecam280 is initiated by the use of a suitable adjustment tool, such as a hex-head wrench for example, with thetool receptor285 to forcibly position the operatingshaft276 against the force of thespring288 to disengage thehexagonal exterior278 of the operatingshaft276 from intimate contact and influence with thehexagonal hole282 in theside272. In such a maneuver, thegroove292 is positioned within thehexagonal hole282, thereby permitting adjustable rotation of the operatingshaft276 and thecam280 to a new position. When the desired rotation is achieved for proper alignment, the adjustment tool is removed, thereby allowing spring action to reposition the operatingshaft276 to cause re-engagement and locking of the portion of thehexagonal exterior278 located inwardly from thegroove292 of the operatingshaft276 with thehexagonal hole282.
• FIG. 13 is a left isometric view showing the junction of theside panel74 and thetop channel76 and the relationship of components attached to and utilized therewith. Shown in particular is thesegmented compartment158 for accommodation of the sidelatch keeper assembly154. Thesegmented compartment160 is similar in construction and includes similarly designated components.
• Each of thesegmented compartments158 and160 includes a notchedpanel294 for accommodation of the operatingshaft276, as well as opposedangled guide panels296 and298 extending in perpendicular fashion from theside panel74. Although theopposed guide panels296 and298 are shown as being planar, they can be of any suitable geometrical shape to offer tool guidance therebetween to align a suitable adjustment tool, such as a hex-head wrench for example, with thetool receptors285 installed in each of the sidelatch keeper assemblies154 and156 within thesegmented compartments158 and160, such as generally shown inFIG. 6. A plurality of access holes300 (FIG. 5) are located extending through theside panel74 for insertion of a tool for actuation of the sidelatch keeper assemblies154 and156.
• FIG. 14 is a rear view of the stackableelectronic display panel2ashowing theconnector framework14 thereof in alignment with and ready to be received by and secured to theLED display module16 thereof by action of the previously described LED displaymodule latching system52.
• FIG. 15 is a rear view of the assembled stackableelectronic display panel2ashowing the aligned and secure mating of theconnector framework14 thereof to theLED display module16 thereof by the use of the LED displaymodule latching system52. Latching is accomplished by operating theactuator mechanism56 to operate theactuator arms58aand58b,and thereby cause thepivotal latches62aand62b(FIG. 3) to engage thecatches73 and75 (FIGS. 3 and 5), respectively.
• Mode of Operation
• The mode of operation is set forth primarily with reference toFIGS. 16-20 with occasional reference to previously described figures. Additional information regarding electronic control and operation using V-Tours computer controller4, a V-Link® video processor5, adata distributor6, a remotetransportable power rack7, cabling, and the like is included later with reference toFIGS. 31-34 showing exemplary options in which the modular display system can be configured.
• FIG. 16 is a rear view showing the upper portion of theconnector framework14 associated with a stackableelectronic display panel2aaligned with the lower portion of theconnector framework14 associated with an overhead stackableelectronic display panel2b.For purposes of brevity and clarity, therear enclosure panels20 and other closely associated components are not shown.FIG. 16 shows theconnector plates92,94,96 and98 at the upper portion of theconnector framework14 associated with the stackableelectronic display panel2ain vertically spaced alignment with the front connectorplate receptor slot130 of the frontconnector plate receptor100, the rear connectorplate receptor slot134 of theconnector assembly104, the front connectorplate receptor slot132 of the frontconnector plate receptor102, and the rear connectorplate receptor slot136 of theconnector assembly106 of theconnector framework14 associated with the overhead stackableelectronic display panel2b,where theconnector framework14 associated with the overhead stackableelectronic display panel2bawaits subsequent and mutual mated and removable attachment to theunderlying connector framework14 associated with the stackableelectronic display panel2a.Although theconnector frameworks14 are not shown in close intimate juxtaposed contact, the operable components thereof are shown in the positions required for secure mutual attachment to one another along the vertical aspect. The functions and relationships of theconnector plates92 and94 with respect to the frontconnector plate receptor100 and associated components and theconnector assembly104 and associated components are identical to the functions and relationships of theconnector plates96 and98 with respect to the frontconnector plate receptor102 and associated components and theconnector assembly106 and associated components, and as such the description of the function of the components of theconnector plates92 and94 with respect to the frontconnector plate receptor100 and associated components and theconnector assembly104 and associated components correspondingly applies to the function of theconnector plates96 and98 in association with the frontconnector plate receptor102 and associated components and theconnector assembly106 and associated components. Prior to mutual mating and removable attachment of theconnector framework14 associated with the overhead stackableelectronic display panel2bto theconnector framework14 associated with the stackableelectronic display panel2a,the slide pins190 and216 of the front spring-loadedslide pin assembly138 and the rear spring-loadedslide pin assembly140, respectively, and the slide pins190aand216aof the front spring-loadedslide pin assembly142 and the rear spring-loadedslide pin assembly144 are positioned to the “disengaged” position, as previously described, awaiting further positioning for capturing of theconnector plates92,94,96 and98. Theconnector frameworks14 of stackableelectronic display panel2aand the overhead stackableelectronic display panel2bare brought into intimate contact by bringing the spring-loaded ball detents166a-166bon the top surface of thetop channel76 of the stackableelectronic display panel2ainto alignment with detent holes (not shown) on the bottom surface of thebottom channel78 of the overhead stackableelectronic display panel2b,as well as intimate contact involving the mutual and respective alignment of theconnector plates92,94,96 and98 with the front connectorplate receptor slot130 of the frontconnector plate receptor100, the rear connectorplate receptor slot134 of theconnector assembly104, the front connectorplate receptor slot132 of the frontconnector plate receptor102, and the rear connectorplate receptor slot136 of theconnector assembly106 of the overhead stackableelectronic display panel2b.Then, slide pins190 and216 of the front spring-loadedslide pin assembly138 and the rear spring-loadedslide pin assembly140, respectively, and the slide pins190aand216aof the front spring-loadedslide pin assembly142 and the rear spring-loadedslide pin assembly144 are positioned to the “engaged” position, as previously described, to extend through the engagement holes92a,94a,96aand98aof theconnector plates92,94,96 and98 and other structure, thereby completing capturing.
• FIG. 17 illustrates the mating of the upper portion of theconnector framework14 of a stackableelectronic display panel2awith the lower portion of theconnector framework14 of an overhead stackableelectronic display panel2band the alignment of the stackableelectronic display panel2awith an adjacent stackableelectronic display panel2nlocated at one side of the stackableelectronic display panel2a.Shown in particular is the use of the rear spring-loadedslide pin assembly144 with theconnector plate98 and the use of the rear spring-loadedslide pin assembly140 with theconnector plate94, as previously described. Theslide pin190aof the front spring-loadedslide pin assembly142, shown in other figures, engages theconnector plate96, and theslide pin190 of the front spring-loadedslide pin assembly138 engages theconnector plate92 in a similar manner, as previously described. The relationship of theslide latch assemblies146 and148 each having alatch256 in the stackableelectronic display panel2ato the slidelatch keeper assemblies154 and156 in the adjacent stackableelectronic display panel2nis also shown. Thelatches256 engage thecams280 of the slidelatch keeper assemblies154 and156. Subsequent adjustment of thecams280 utilizing the operatingshafts276 causes interaction with thelatches256 for vertical adjustment ofadjacent connector frameworks14 and thus of stackableelectronic display panels2a-2nto bring the edges of adjacent stackableelectronic display panels2a-2ninto alignment to provide for seamless viewing of the LED pixels.
• FIG. 18 illustrates beveled surfaces included in the geometrical configuration of the upper portion of theconnector framework14 of a stackableelectronic display panel2ain distanced alignment with the lower portion of theconnector framework14 of an overhead stackableelectronic display panel2bhaving opposed complementary beveled surfaces, wherein adjustability about the junction of the matedconnector plate96 andslide pin190aof the front spring-loadedslide pin assembly142, shown inFIG. 19 (and about the junction of the matedconnector plate92 andslide pin190 of the front spring-loaded slide pin assembly138), is provided to facilitate rotational adjustment of the stackableelectronic display panels2a-2nabout the “X” axis (forward and rearward tilt) by actuation of thethumbwheel adjusters174 along the threadedshafts172. The profile of the frontconnector plate receptor102 includes adjacent andopposed bevels302 and304 which extend along the bottom surface of thebottom channel78 to and including the frontconnector plate receptor100. The profile of the upper portion of theside panel74 includes opposedbevels306 and308 opposing thebevels302 and304 and extending along the top surface of thetop channel76 to and including the upper portion of theside panel72. Thebevel308 starts at the upper portion of theside panel74 in close proximity to theconnector plate96 and is interrupted to further continue at the upper portion of theside panel74 in close proximity to theconnector plate98.
• FIG. 19 is a view likeFIG. 18 but illustrating the upper portion of theconnector framework14 of the stackableelectronic display panel2ain close alignment with the lower portion of theconnector framework14 of the overhead stackableelectronic display panel2b.
• FIG. 20 is a rear view of ascreen12 incorporating a plurality of stackableelectronic display panels2a-2n.In addition to mated and secured attachment along the vertical aspect as previously described, juxtapositional mating and secured attachment along the horizontal aspect is also provided. For example, theside panel72 of the stackableelectronic display panel2acan be juxtaposingly aligned to theside panel74 of the stackableelectronic display panel2nwith the assisted guidance offered by the detent holes164a-164cof theside panel74 of the stackableelectronic display panel2nand the corresponding spring-loaded ball detents162a-162cof theside panel72 of the stackableelectronic display panel2a.For example and illustration, thelatches256 on theside panel72 of the stackableelectronic display panel2aare actuated to engage thecams280 on theside panel74 of the stackableelectronic display panel2n.Thus, the stackableelectronic display panels2aand2nare juxtapositionally mated in secured attachment along the horizontal aspect and can be adjusted, as previously described, in a vertical fashion to provide alignment between the stackableelectronic display panels2a-2n.
• A plurality of stackableelectronic display panels2a-2ncan be aligned, mated and attached along the vertical and horizontal aspects, as described. Overall integrity along the vertical aspect is enhanced by the robustness of theconnector plates92,94,96 and98 and the robustness of the frontconnector plate receptors100 and102 and theconnector assemblies104 and106 as well as the interlocking capabilities thereof where each of the corners; i.e., theconnector plates92,94,96 and98, are mutually attached to the frontconnector plate receptors100 and102 andconnector assemblies104 and106 of a vertically situated overhead stackableelectronic display panel2a-2nutilizing multiple positive locking schemes. Aligned attached mating along the horizontal aspect incorporating the relationship of thelatches256 and thecams280 located in theside panels72 and74 incorporated with the attached mating along the horizontal aspect incorporating theconnector plates92,94,96 and98, the frontconnector plate receptors100 and102, andconnector assemblies104 and106 provides a synergistic structure having alignment capabilities coupled with structural robustness.
• The stackableelectronic display panels2a-2nare interconnected by cables which utilize thesignal receptacles64 and66 on therear enclosure panel20 and are connected to computerized control systems known to the art to control the content displayed utilizing themodular display system1. Optionally, themodular display system1 can include border attachment points, rails, frames, and the like, and the stackableelectronic display panels2a-2ncan be suspended or supported from the bottom by suitable mounting structure. Although the stackableelectronic display panels2a-2nare shown as squares, other suitable shapes, such as a rectangle, may be utilized. The teachings of the invention may be utilized to provide structure for support of incandescent lighting, flat panel displays, LCD displays, graphic nonelectrical displays, or displays of other types.

• Additional Features
• A. Display Panel Design
• Durable, Lightweight and Water Resistant. Each stackableelectronic display panel2a-2nis designed with lightness, ruggedness and water resistance in mind. The result is an IP-65 rated, strong, resilient, weatherized stackable electronic display panel that weighs only 7 kg (15.40 lb.) and measures approximately a half meter. The combined features make the stackableelectronic display panels2a-2nroad-ready and equipped for the quickest possible setup in any environment.
• Low Heat and Low Noise. Efficient power structure minimizes heat build-up within the stackableelectronic display panels2a-2n,maximizing internal electronics lifetime. In addition, the ultraefficient electronics use arear heat sink50 for ventilation thereby creating minimal noise, and making the stackableelectronic display panels2a-2nvirtually silent during operation.
• Serviceability. The stackableelectronic display panels2a-2nare readily serviceable from either the front or the rear. A hex wrench fits inside from the front or the rear and releases the LED displaymodule latching system52 that holds a stackable electronic display panel in place to aconnector framework14. The quick release makes changing out stackableelectronic display panels2a-2neasy and fast.
• Design Flexibility. The modular display system gives designers the flexibility to create innovative video displays. The approximately half-meter by half-meter stackableelectronic display panels2a-2nshape into virtually any configuration, whether traditional or artistic. The stackableelectronic display panels2a-2ncan use rear support structure in the form of the describedconnector framework14 or custom structures can be designed and built to support the stackableelectronic display panels2a-2n.
• Cast Aluminum Structure. Eachconnector framework14 is a lightweight, durable, cast aluminum structure to provide support for the affixedLED display module16. Weighing 20 lb. (9.1 kg.) alone or 35 lb. (16.1 kg.) when combined with theLED display module16, theconnector framework14 is capable of hanging up to 22 stackable electronic display panels, creatingdisplays 36 feet (11 m.) in height. When mounting from the ground, theconnector framework14 can support up to 10 panels high using ground stand mounting structure, creating displays up to 16 feet (5 m.) high.
• Express Assembly and Superior Seam Control. Eachconnector framework14 includes four slide pins that interlock with the connector plates on theconnector framework14 below to thereby secure the connector frameworks in place with one another. Adjustable side latch assemblies actively draw the panels together vertically eliminating seams between panels. Thumbwheel adjusters on the rear of eachconnector framework14 adjust horizontal tolerances and guarantee a tight fit and continuous look.
• Mounting Flexibility. In addition to the castaluminum connector frameworks14, a variety of other structure options are available. Large scale panel frames can be used for quicker setup of larger displays and cabinet-style frames can be used for permanent installations.
• B. Signal Communications
• Redundant Signal. Redundant signal masks signal failures and maximizes display uptime. The proactive feature ensures against the unexpected, keeping imagery constant and unbroken on a display. The innovative, redundant signal design passes image and diagnostic data from display panel to display panel in two directions. If a signal interruption occurs from one direction, the affected display panels automatically switch to the backup signal and a report of the situation is then given back to the computer controller.
• Signal Connectors and Cables. An industry standard, rugged, quick release signal connector guarantees a watertight bond between stackable electronic display panels. An audible, positive-lock click indicates a connector fits snugly in place, keeping the elements out. If a supplied signal cable becomes damaged, it can be temporarily replaced with a standard network cable available from almost any electronics store. This quick fix solution eliminates waiting on manufacturer-supplied cables to keep the show going.
• Operational Status Indicators. Operational status LEDs on the backside of an LED display module give a quick visual indication of the LED display module's operational status. The signal indicators turn off when the data path to the LED display modules is interrupted, alerting support personnel that further examination is required.
• C. Power Delivery
• Remote Power System. To keep noise away from the display, a remote transportable power delivery system or rack that can be located up to 150 feet (45.7 meters) away from the display is provided. The external remote power delivery system removes the power supplies from the display, resulting in a drastically lighter display panel and reducing heat for extended uniformity.
• Power Connectors. An industry standard, rugged, quick release power connector guarantees a watertight bond between display panels. An audible, positive-lock click indicates a connector fits snugly in place, keeping the elements out.
• Hot-Swappable Power. The transportable power rack can be located up 150 feet (45.7 meters) away from the display and allows power units inside the rack to be hot-swapped for one another, keeping a constant supply of power to the display panels. The power rack contains several power units that distribute the power evenly to the display panels. Should one power unit fail, the remaining units pick up the power load and keep the display running. An indicator alerts support personnel of a failed power unit, allowing them to replace the unit for a new one without shutting off power to the display panels.
• Operational Status Indicators. Operational status LEDs on the backsides of the LED display modules give a quick visual indication of the operational status of the LED display modules. The power indicator illuminates when the LED display module receives power, signaling to support personnel that the LED display module works correctly.
• Various modifications can be made to the present invention without departing from the apparent scope hereof.
