`
`[0001] The present application claimspriority from U.S.
`Provisional Application No. 60/914,289, filed Apr. 26, 2007,
`whichis incorporated herein by reference asif set forth in full
`below.
`
`BACKGROUND OF THE INVENTION
`
`[0013] A still further aspect of the present invention is to
`provide a telescopic light assembly thatis directly mounted to
`the transport enclosureto a vertically upright position and is
`stowed in the vertically upright position.
`[0014] A still further aspect of the present invention is to
`provide an electric cable chamber positioned immediately
`adjacentthe telescopic mastof the telescopic light assembly.
`The electric cable chamber stores a coiled electric cable
`which delivers powerto lights of the telescopic light assem-
`bly. The electric cable chamberis arranged to automatically
`dispense therefrom as the telescopic mast
`is raised and
`receive therein the coiled electric cableas the telescopic mast
`is lowered.

`ers and, more particularly, to an easy-guide portable light

`fully recessed into a transport enclosure when stowed.
`[0004]
`2. Background
`[0005]
`Portable light towers are currently manufactured for
`on-shore use. These portable light towers include a generator
`with a pair of wheels. These land based portable light towers
`are not built for the off-shore environment and require exten-
`sive retrofitting.
`[0006]
`Furthermore, when transported the portable light
`towers are not fully recessed in or confined in a transport
`enclosure. Instead, parts of the lights and other components
`are often unprotected and are damaged upon arrival to the
`off-shore site. This may lead to long delays in an environment
`wherelost time is very costly.
`[0007] The portable light tower systems are also stowed in
`a horizontal position. For operation, the mast of the system is
`rotated from a horizontal position to a vertical position.
`Thereafter, the mast can be telescoped. This increases the
`mechanicalparts that can fail on the jobsite.
`[0008] Thus, there is a need for a portable light system that
`can be fully protected during transport and eliminates the
`rotation of the mast to and from a horizontal position to a
`vertical position.

`
`SUMMARYOF THE INVENTION
`
`[0009] An aspect of the invention includes a system com-
`prising: a transport enclosure constructed and arranged for an
`off-shore environment and having a horizontal perimeter
`boundary anda vertical perimeter boundary. The system also
`includesa telescopic light assembly mountedto the transport
`enclosure and operable to telescope vertically to extend
`beyond the vertical perimeter boundary and which, when
`stowed, is fully recessed and confinedin the transport enclo-
`sure within the vertical and horizontal perimeter boundaries.
`[0010] A further aspect of the present invention is to pro-
`vide the transport enclosure with stabilizing channels sup-
`ported from twoparallel horizontal support membersin prox-
`imity to receive free ends of the left and right arms when the
`mast is essentially at zero degrees.
`[0011] A further aspect of the present invention is to pro-
`vide a telescopic mast which comprises a plurality of concen-
`tric telescoping sections, wherein a top end of each telescop-
`ing section has a plurality of pads to create a frictionless
`surface between two adjacent telescoping sections.
`[0012] A still further aspect of the present invention is to
`provide Teflon pads as frictionless surfaces so that as the
`telescopic mast is telescoped upward or downward in an
`easy-glide manner without the need for oils or other lubri-
`cants.

`[0046] The stabilizing channel 68 is generally V-shaped.
`Nevertheless, other shapes may be used. In this embodiment,
`the width of the lowest end of the stabilizing channel 68 is
`narrowerthanthe upper end ofthe stabilizing channel 68. The
`width ofthe lowest endofthe stabilizing channel68 limits the
`movement forward and backward ofthe free end ofthe cross-
`bar member26 or arm thereof.
`
`146a-146c are coupled to the pulley 146 attached to the
`telescoping section adjacent to and above the telescoping
`section to which each cable is terminally attached.
`[0039]
`Inthe exemplary embodiment, the plurality of lights
`28 are arrangedin pairs. Onepair oflights 28 is on a left arm
`of the crossbar member 26 while the other pair is supported
`from the right arm of the crossbar member26. Each light 28
`is adjustably mounted, to the left arm or the right arm, via a
`bracket 30. In the views, there are four lights 28. Neverthe-
`less, more orless lights may be included.
`[0040] Each of lights 28 may include a metal Halon (Class
`1 Div 2) 400 Watt Light with fixture (FIG. 4). The lights 28
`further include a retractable cord (not shown) anda circuit
`breaker protected weatherproof enclosure 29.
`[0041] The bracket 30 is generally U-shaped and can be
`adjustably rotated essentially 360° about the arm in the
`Y-plane andfastenedvia fastener 32. As the bracketis rotated,
`the light enclosure 29 is rotated accordingly. The fasteners 34
`to fasten the light enclosure 29 to the bracket 30 allows the
`light enclosure 29 to be adjusted in a 360° rotation about the
`X-axis while the bracket 30 is stationary or fastened via
`fastener 32. As can be readily seen, the bracket 30 provides
`multiple degrees of variability for orienting the lights 28.
`[0042] The skid 50 has fixedly coupled thereto a top-
`mounted cage 60. Together the skid 50 and cage 60 form a
`transport enclosure to protect and carry the telescopic light
`assembly 20. The skid 50 has a generally box shaped foot
`print which may be rectangular or square. The skid 50
`
`[0047] As can be appreciated, the width and height of the
`transport enclosure is constructed to fully recess or confine
`the telescopic light assembly 20 whenin the stowedposition,
`as best seen in FIG. 1. In the exemplary embodiment, the
`width and height of the transport enclosure define the hori-
`zontal and vertical perimeter boundaries of the transport
`enclosure. The horizontal and vertical perimeter boundaries
`ofthe transport enclosure closely track (with minimum clear-
`ance) the height and width ofthe telescopic light assembly 20
`when in the stowed position such that the telescopic light
`assembly 20 is fully lowered.
`[0048]
`Inother words,the transport enclosure is minimized
`in size so that its size does not take up unnecessary real estate
`on anoil-field platform orotheroff-shore structure while also
`fully enclosing the telescopic light assembly 20.
`[0049] Ascan be appreciated during transport, loading and
`unloading, or when on an off-shore platform or drillingrig,
`the telescopic light assembly 20 could moveasthe result of
`strong impact forces. The stabilizing channels 68 stabilize the
`left and right light supporting arms defined by the crossbar
`member 26 when the telescopic light assembly 20 is in a

`
`stowed position. Thus, the impact forces articulated to the
`plurality of lights 28 may be reduced to minimize breakage of
`the light bulbs 31 (FIG.4).
`[0050] Referring again to FIGS. 1 and6, the left side of the
`easy-guide portable light tower system 10 includesa storage
`box 80 having an enclosure 82 closed via lid 84. The storage
`box 80 is mounted on the skid 50. Oneside of the storage box
`80 is hingedly coupled to the enclosure 82. The other side of
`the lid 84 is adapted to be held closedviaat least one latching
`or locking member 86. In general, the storage box 80 is
`similar to a tool box. The storage box 80 is made of a non-
`corrosive metal such as without limitation aluminum.
`
`[0051] With specific reference to FIGS. 10, 12, 13 and 16,
`the engine/generator assembly 100 is housed in an engine/
`generator housing 102. The rear of the housing 102 has a
`plurality of access panels 104 and 106. The left side of the
`housing 102 includes a door 108 having a vent 110 formed
`therein. In the housing 102 adjacentthe door 108 is a radiator
`112. FIGS. 12 and 13 illustrate the engine/generator sub-
`assembly 100 and various components thereof.
`[0052]
`In the exemplary embodiment,
`the engine is a
`Kubota Diesel Engine which is three-cylinder liquid cooled
`(14 hp @ 1800 rpm). The engine has a mountedradiator 112,
`a coolant recovery tank, an air cleaner, a manual air intake
`shutdown 116 (FIG. 12), anda muffler. Asbest seen in FIG.1,
`the top of housing 102 has an emergency shutdown handle
`116a to shutdown the air intake. Furthermore, the engine
`includesa spark arrestor, a 12 volt electric start, a secondary
`fuel filter, an electric fuel pump with a primary Racor fuel
`filter, F.W. Murphy Engine Controls, Hi Temp/Low Oil Shut-
`down, Hour Meter, and an EZ oil drain valve.
`[0053] The generator of the exemplary embodiment is
`manufactured by Newage. The generator produces 8 KW. The
`generator includes a dedicated single phase, 4-Pole, Single
`Bearing system. The generator operates at 1800 rpm, 120/
`240V. The generator is AC Brushless and is epoxy coated. The
`generator has an automatic voltage regulator, self excited,
`dynamically balancedrotor, and is fan cooled. The engine and
`generator above are just examples of suitable engines and
`generators and may be substituted with similar devices of
`other manufacturers.
`
`FIG. 10 showsa control panel 120 accessed through
`[0054]
`the access panel 104. FIG. 11 illustrates a top view of the fuel
`tank 180. The fuel tank 180 stores the fuel for operating the

`FIG. 2 showsa (right) side view of the easy-guide
`portable light tower system 10 of FIG. 1. FIGS. 3 and 5 show
`viewsofthe telescopic light assembly 20 in the stowed posi-
`tion. With reference to FIGS. 5 and 7,the easy-guide portable
`light tower system 10 further includes an electric cable feed
`chamber 130 parallel and behindthe telescopic mast 22 ofthe
`telescopic light assembly 20. The electrical cable feed cham-
`ber 130 houses (stores) and protects the electric cable 132
`therein. The electric cable 132 provides powerto the plurality
`of lights 28. The electrical cable 132 is shown having a coiled
`or spiraling profile. Under gravity, the electric cable 132 is
`automatically stowed in and dispensed from the electric cable
`feed chamber 130.
`
`[0056] Gravity and/or the coiled properties of the electric
`cable 132 allow the cable 132 to automatically fall or re-coil
`
`in the electric cable feed chamber130. This feature eliminates
`loose cable wires from just hanging around on the skid 50 or
`on other structures. Thus, the electric cable 132 has less
`chances of being tangled when the telescopic mast 22 is
`raised. This also eliminates other entanglementofthe electric
`cable 132 since it is neatly stowedin the electric cable feed
`chamber 130.
`
`FIG. 7 showsa rear view of the easy-guide portable
`[0057]
`light tower system 10 of the present invention with the tele-
`scopic light assembly 20 in a fully telescoped position. The
`coiled electric cable 132 is pulled from the electric cable feed
`chamber 130 as the telescopic mast 22 is raised or telescoped.
`As the telescopic light assembly 20 is lowered, the coiled
`electric cable 132 is automatically filled or recoiled in the
`electric cable feed chamber 130.
`
`FIG. 6 showsa front view ofthe easy-guide portable
`[0058]

`scopic light assembly 20 in a fully telescopedposition. FIG.
`8 showsa front view of the easy-guide portable light tower
`system 10 of the present invention with the telescopic light
`assembly 20 in an intermediary telescoped position and
`rotated counter-clock wise.
`
`[0059] With specific reference to FIGS. 8 and 14, the tele-
`scopic mast 22 includes a band 150 with a locking pin 152.
`The locking pin 152 locksthe telescopic mast 22 to a particu-
`lar degree of rotation in the Y-plane. In FIG. 1, the degree of
`rotation is 0°. FIG. 8 illustrates other degrees of rotation at
`whichthe telescopic mast 22 can be locked.
`[0060]
`In operation, the telescopic mast 22 is telescoped or
`raised by rotating the winch handle 144. As handle 144 is
`rotated, each mast section 24 is raised an equivalent amount,
`the cables 142a-142c being held in tensionasthe sections are
`raised.
`(FIGS. 8 and 9). Thus, various heights can be
`achieved.
`In the exemplary embodiment,
`the maximum
`height is 16 feet. However, other heights can be achieved with
`different lengths of the telescoping sections 24.
`[0061] Referring now to FIGS. 9, 14 and 15, the top of the
`mast base 22a and the top of the intermediate telescoping
`sections 24 each have a plurality of pads 160 to create a
`frictionless surface between two adjacent and concentric tele-
`scoping sections 24 or mast base 22a. Each pad 160 is remov-
`ably coupledto a bracket 162 via fasteners 164. The brackets
`162 are secured to the top end of the mast base 22¢ and the
`intermediate telescoping sections 24. At least three sides of
`the sections 24 have a bracket associated therewith. Each
`
`bracket has a pad 160.
`[0062]
`Inthe exemplary embodiment,the plurality offric-
`tionless surfaces or pads 160 are made of Teflon, Graphite or
`the like. Thus, a frictionless surface is created without the
`need for oil or other lubricants.
`
`In FIGS. 1 and 2, a switch panel 172 is positioned
`[0063]
`below the poweroutlets 170 to turn on andoffthe outlets 170.
`The switch panel 172 is shown behindthe partially removed
`door. (FIG. 2). The bank of outlets 170 includes at least one
`emergency shutoff switch 174. In the exemplary embodi-
`ment, two emergency shutoff switches 174 are provided. The
`outlets 170 are split between the two switches 174. Neverthe-
`less, other configurations may be used. In the exemplary
`embodiment,all of the outlets 170 are 110V. However, other
`voltages may be used.
`[0064] The power outlets 170 include 110V Explosion
`Proof Receptacles (Class 1 & 2), circuit breaker protected.
