`LIGHTING ASSEMBLY RAISED AND
`LOWERED ALONG POLE
`
`TECHNICAL FIELD
`
`This invention relates to a lighting assembly adapted for
`mounting to a pole.
`
`BACKGROUND ART
`
`Athletic fields serving both the amateur and professional
`ranks of sports such as soccer, football and baseball, often
`have lighting units or fixtures available to provide sufficient
`light
`to permit sporting events to take place during the
`twilight and evening hours. Such lighting units are com-
`monly attached to a pole having a service platform mounted
`to the pole top,
`thereby providing a stable surface for
`supporting an operator when maintenance of the lighting
`unit
`is necessary. Access for repair and maintenance of
`features such as lamp replacement andballast repair of the
`lighting unit is typically via pole steps or a bucket truck. But
`pole steps may provide undesired parties with access to the
`lighting units and the use of a bucket truck may be awkward
`and time consuming, as well as inaccessible to particular
`areas and impracticable under certain circumstances.
`Further, current lighting fixture and pole assemblies com-
`monly include a low numberof lighting units, thus requiring
`more frequent and closer placement of the assemblies in the
`field. Moreover, the lighting units of these assemblies gen-
`erally are focused in a single direction, thereby necessitating
`multiple assemblies positioned close to each other should
`twofields be placed side-by-side and require lighting.
`Consequently, a need has developedfor a lighting fixture
`for mounting to a pole, which is adapted for lighting outdoor
`fields and sporting venues. The lighting fixture should be
`easy to access and maintain. Suchfixture should also resolve
`the need for multiple fixtures positioned close to each other.
`Such device should further be able to light adjoining field or
`areas without great difficulty and permit orientation of
`attached luminaires in one or more directions.
`
`BRIEF SUMMARY OF THE INVENTION
`
`invention to
`is an object according to the present
`It
`provide a lighting assembly whichis easier to maintain and
`access.
`
`It is another object according to the present invention to
`provide a lighting assembly which provides sufficient light
`to require fewer lighting fixtures in proximity to each other.
`It is still another object according to the present invention
`to provide a lighting assembly whichis illuminate in more
`than one direction.
`
`It is yet another object according to the present invention
`to provide a lighting assembly whichis able to illuminate
`adjacent areas or wherein the lighting units are capable of
`being oriented for directing light in different directions.
`In carrying out the above objects, features and advantages
`of the present invention, provided is a lighting assembly
`adapted to receive lighting fixtures and whichis capable of
`being raised and lowered along the length of an attendant
`pole having a longitudinal axis. This raising and lowering of
`the system is accomplished by a transport mechanism hav-
`ing a plurality of cables which extend from the lighting
`system to the base of the pole. The lighting system includes
`at least one support member whichis co-axially aligned with
`the longitudinal axis of the pole. Further included is a pair
`of transverse members which are oriented substantially

`cross-members extending therebetween. Each ofthe pair of
`transverse members is disposed on opposite sides of the at
`least one support member. In one embodiment,a plurality of
`fixture mounts are includedfor attaching the lighting fixtures
`to each of the pair of transverse members.
`In other
`embodiments,the pair of transverse members define one of
`either a horizontal plane or an angled plane. Still in other
`embodiments,the pair of transverse membersand theat least
`one support member share a commonplane. Still further,
`each of the pair of transverse membersis substantially long
`relative to the diameter of the attendant pole.
`Yet another embodimentof a lighting system according to
`the present invention includes a frame having front and rear
`transverse members whichareoriented parallel to each other
`and have a plurality of cross-members extending
`therebetween, the front and rear transverse members and the
`plurality of cross-members defining a plane. This lighting
`system also includes a transport device having an annular
`support member whichis concentrically disposed about the
`pole in a horizontal plane. The front and rear transverse
`members are each mounted to opposite sides of the annular
`support member. The transport mechanism also includes a
`plurality of cables attached to the support memberin order
`to permit the control of raising and lowering the frame along
`the length of the pole.
`In a preferred embodiment, the frame has a parallelogram
`shaped cross-section which is defined by a first planar face
`and a second planar face which are oriented opposite each
`other, and is further defined by a first angled face and a
`second angled face oriented opposite each other. Thefirst
`planar face is defined by an upper transverse member and a
`one of the front and rear transverse members. The second
`
`planar face is defined by a lower transverse member and an
`other of the front and rear transverse members. The first
`
`angled face is defined by the lower transverse member and
`the other of the front and rear transverse members. The
`
`second angled face is defined by the lower transverse
`member and the one of the front and rear transverse mem-
`bers. In one embodiment, the first and second planar faces
`are each substantially perpendicular to horizontal plane. In
`another embodiment, each of the front, rear, upper and lower
`transverse members havelighting fixtures mounted thereon.
`The above objects and other objects, features and advan-
`tages of the present invention are readily apparent from the

`BEST MODE FOR CARRYING OUT THE
`INVENTION
`
`Referring to FIG. 1 of the drawings, shown therein is a
`lighting unit and pole assembly 10 according to the present
`invention. Particularly, lighting unit and pole assembly 10
`includes a pole 12, a frame 14, and a plurality of luminaires
`20 (or lighting fixtures). In the embodiment illustrated in
`FIGS. 1 and 2, frame 14 resembles a cage and thus may also
`be referred as a lighting cage. Lighting umit and pole
`assembly 10 further includes a raising/lowering system
`subassembly 11 (or a transport mechanism) which itself
`includes, among other components, a support member 16
`and a plurality of hoisting cables 18, as will be discussed
`more fully herein. Support member 16 preferably has an
`annular shapeas illustrated in FIGS. 1, 3 and 5. Pole 12 is
`sufficiently tall to permit the light distribution desired for the
`intended application and has a longitudinal axis.
`With regard to the mobility of frame 14 and support ring
`16 along pole 12, in the embodiment disclosed in FIG. 1,
`there are provided three hoisting cables 18 for lowering and
`raising frame 14 along the length of pole 12 in conjunction
`with support member 16. Cables 18 are commonly heavy-
`duty aircraft cables formed of aircraft-grade steel and zinc
`electroplated to meet Type A Federal Specification RR-W-
`410a. Frame 14 and support member 16 are preferably
`formed of a grade of galvanized steel sufficient to withstand
`the environmental conditions an outdoor assemblyis likely
`to encounter. Of course, the use of assembly 10is not limited
`to outdoor applications and mayalso be used to illuminate
`indoor settings, such as stadiums or arenas, as well.
`With reference again to FIG. 1, it is shown therein that
`support member 16 is centrally disposed within frame 14.
`Raising/lowering system 11 is one which is capable of
`moving frame 14 about pole 12 and along the length of pole
`12 and its general operation is well-known in the art. For
`example see U.S. Pat. No. 4,198,022 entitled “Power Cable
`Guide For High-Mast Luminaire Raising and Lowering
`System”, which is incorporated fully herein by reference,
`and is the preferred means and method for moving frame 14
`along the length of pole 12 from generally ground level to
`the top or upper region of pole 12 via hoisting cables 18.
`Generally, the hoisting cables 18 are mounted to and extend
`from support member16 through a pulley system 19 thatis
`typically located at the top of pole 12, under poletop cover
`21 as shown in FIG. 1 and 11. Cables 18 extend down
`throughthe interior 23 of pole 12 to the base of the pole (see
`FIG. 12) where they connect to a power winch assembly 25

`which operates the transport mechanism,as is well known in
`the art. It is also in the base of pole 12 where the poweris
`provided to assembly 10, as is knownin theart.
`In the embodiment illustrated in FIG. 1 of the drawings
`herein, no affirmative contact
`is made between support
`member 16 and pole 12. However, in other embodimentsit
`is contemplated that support member 16' may be centered
`about pole 12, as shown FIG. 13, by way of engagement
`between pole 12 and support member 16' via an apparatus
`and method knownin the art and generally disclosed in U'S.
`Pat. No. 3,847,833 entitled “Method and Apparatus For
`Centering A Luminaire Support”, which is incorporated
`fully herein by reference. It is noted in the embodiment
`shown in FIG. 1 that, in operation, support member 16 is
`oriented in a horizontal plane which is generally parallel to
`the ground, is disposed concentrically about pole 12, and is
`co-axially aligned with pole 12.
`With reference again to FIGS. 1 and 2, frame 14 includes
`a pair of transverse members—front transverse member 24
`and rear transverse member 26—which are oriented sub-
`
`stantially parallel to each other and thereby define a plane.
`Transverse members 24 and 26 are each mounted to opposite
`sides of support member 16 through corresponding mount-
`ing brackets 22, and accordingly, are also disposed on
`opposite sides of pole 12. Each of transverse members 24
`and 26 is longitudinally aligned relative to pole 12 and has
`a relative length greater than the diameter of pole 12. Each
`of transverse members 24 and 26 is oriented generally
`perpendicular to pole 12, although the resultant plane
`defined by the pair of transverse members may not be
`perpendicular to pole 12.
`In the embodiment shownin FIG. 4, support member 16
`is co-planar with the plane defined by front
`transverse
`member24 and rear transverse member 26, said plane also
`being generally parallel to the ground. Of course, as previ-
`ously mentioned, support member 16 need not be co-planar
`with transverse members 24 and 26 to achieve the teachings
`according to the present invention.
`Support member16 is attached or mounted to frame 14 by
`way of a pair of support member mounting brackets 22.
`Specifically, each one of the pair of mounting brackets 22 is
`attached to a corresponding one of the front and rear
`transverse members 24, 26, as is shown in FIG. 5, which is
`a sectional view taken along the line 5—5 of FIG. 4.
`As illustrated in FIG. 3, each mounting bracket 22 is
`shownattached to support member 16 by wayofa plurality
`of screws with hex heads or threaded studs with hex nuts
`attached thereto 28,
`in conjunction with corresponding
`washers 30. Of course, it is contemplated that mounting
`bracket 22 may be attached to support member 16 by a
`variety of appropriate fastening methods, of which the one
`illustrated is just an example. Also shown in FIG. 3 is a
`relatively smaller channel mounting bracket 32 mounted to
`support member 16 in a manner similar to that described
`above in association with mounting bracket 22. Smaller
`mounting bracket 32 is typically used to mount a wiring
`chamber 70 for providing electrical powerto the plurality of
`luminaires 20 via a main power cable 72, best shown in
`FIGS. 1 and 7-9.
`
`As is knownin the art, power cable 72 runs from a power
`inlet 70 over a single pulley, down throughthe interior of the
`pole to the pole base, where it connects to a power source by
`way of a twistlock disconnect and circuit breaker. In the
`region of the disconnect, power cable 72 is attached to the
`hoisting cables 18 such that when frame 14is to be lowered,
`power cable 72 is disconnected from the power source so

`that the bulk of the power cable moves outwardly through
`the pole, around the powercable pulley at the top of the pole
`and downwardly onthe outside of the pole with the lowering
`lighting assembly. (See FIGS. 11-12).
`As is further illustrated in FIGS. 1, 3, and 5, each
`mounting bracket 22 is mountedto its corresponding one of
`the front and rear transverse members 24 and 26 by wayof
`a plurality of screws and washers, similar to the fasteners
`described above regarding the attachment with support
`member 16. Particularly,
`it is noted in FIG. 2 that each
`mounting bracket 22 has a plurality of holes 34 formed
`therein, which are aligned with a plurality of holes 36
`formed in a corresponding transverse member 24 and 26
`through which screwsor other fastening meansare inserted
`for attaching each bracket 22 to a transverse member24, 26.
`With reference again to FIG. 5, note that a plurality of
`cross-members 38, 38' is provided for securing front trans-
`verse member 24 to rear transverse member 26 and for

`Similarly, with reference again directed to FIG. 6, lower
`vertical member 52 is mounted at its upper end 53 to rear
`transverse member 26, while lower cross-member 54 is
`mountedat its upper end 55 to front transverse member 24.
`Like their counterpart members 44 and 46, note that lower
`vertical member 52 and lower cross-member54are attached
`to each other at location 56 to form the triangular-shaped
`lower section 58. Upper and lowervertical members 44, 52
`are shown as generally perpendicular to the corresponding
`transverse member 24, 26, respectively, to which they are
`attached. It is further noted in FIG. 6 that upper and lower
`diagonal cross-members 46 and 54 are generally parallel to
`each other, while upper and lower frame members 44 and 52
`are likewise generally parallel to each other. Note with
`reference to FIG. 2 that there are four lower vertical mem-
`bers 52 and four lower cross-members 54 across the trans-
`verse length of lighting cage 14.
`With further reference to FIGS. 2 and 4, shown provided
`therein is a pair of upper transverse members 60 which are
`providing greater stability to the lighting cage 14. Note that
`20
`a total of four cross-members 38, 38' are shown in FIG. 5.
`co-linearly aligned with each other and which formaline
`In FIGS. 1-2 and 4-5 itis illustrated that the plane defined
`along which each upper vertical member 44 meets with a
`by cross-members 38, 38' is generally co-planar with the
`corresponding upper cross-member 46. It is contemplated
`plane defined by front and rear transverse members 24 and
`that
`the pair of upper transverse members 60 may be
`26 as well as that of support member 16. Of course, while
`provided as a single upper transverse member. FIGS. 2 and
`one cross-member38 lies above another cross-member38',

`they maybesaid to lie generally in the same plane for the
`luminaires 20 are attached to upper transverse members 60,
`the result of which is illustrated in FIGS. 1 and 7-8.
`purposes herein. Each cross-member38, 38' is attached at
`either end to the front
`transverse member 24 and rear
`transverse member 26 at points 40 and 40'. Each cross-
`member 38 is also attached to its corresponding cross-
`member 38' at a position 42 centrally located along each
`cross-member38, 38'. Like before, these attachments 40, 40'
`and 42 are shownto be screws, nuts and washers, but may
`also be any of a variety of fasteners. Transverse members 24
`and 26 each provide for a mounting base to which opera-
`tively mounts a plurality of luminaires 20. As shownin FIG.
`1 and as more fully shownin FIGS. 7-9, four luminaires 20
`are mounted to front transverse member 24 and four lumi-
`naires 20 are mounted to rear transverse member 26.
`
`With reference again to FIG. 2 of the drawings,illustrated
`therein is a perspective view of frame 14 of assembly 10
`according to the present invention. Frame 14is illustrated
`herein as a framed unit having various transverse and
`cross-members which define the various faces of cage 14.
`The various transverse members also provide mounting
`bases to which luminaires 20 may be mounted or otherwise
`attached, as shown in FIGS. 1 and 7-10.
`With attention now directed to FIG. 6, shown therein is a
`side elevational view of lighting cage 14 according to the
`present
`invention. Note that various cross-members and
`transverse members define a triangular shaped area both
`above and below the horizontal plane defined by front and
`rear transverse members 24, 26 and cross-members38, 38'.
`Moreparticularly, note that the side elevational views shown
`in FIGS. 6 and 9 resembles a parallelogram in shape.
`Particularly, in forming this parallelogram shaped cross-
`section, an upper vertical member 44 is mountedat its lower
`end 45 to front transverse member 24, while upper cross-
`member46 (or brace) is mountedat its lower end 47to rear
`transverse member 26 via mechanical fasteners including,
`but not limited to, bolts and nuts, rivets, or welding. Note
`that the upper portions of each upper vertical member 44 and
`upper cross-member46 are attached to each otherat location
`48 to form the triangular upper section 50. As shownin FIG.
`2, illustrated therein are four upper vertical members 44 and
`four upper cross-members 46 across the transverse length of
`frame 14.

`mounted via standard fasteners through hole 62 for mount-
`ing to a corresponding transverse member 24, 26, 60, 64.
`The adjustable functionality of mounting bracket 73 also
`allows luminaires 20 to move and to be directed in various
`
`directions and orientations with respect to its corresponding
`transverse member. For example, refer to FIG. 10 which
`illustrates that front luminaires 20 may be oriented in one
`direction, while rear luminaires 21 may be oriented in a
`second—in this case opposite—direction. Thus one lighting
`cage and pole assembly 10 maybeused to illuminate two
`distinct areas, such as adjoining playingfields.
`FIG. 2 and 7 also illustrate a lower transverse member 64
`
`which defines a line along which each lower frame member
`52 is attached to a corresponding lower diagonal member 54.
`Lower transverse member 64 also has mounting holes 66
`allowing a plurality of luminaires 20 to be attached to lower
`transverse member 64, as shown in FIGS. 1, 7 and 9.
`Again with reference to FIGS. 7-9, sixteen luminaires 20
`are provided in association with cage 14: four along front
`transverse member24, four along lower transverse member
`64, four along rear transverse member 26, and four along
`upper transverse members 60. As an alternate description,
`eight luminaires 20 are mounted or otherwise suspended
`from a front upper planar face 68 of frame 14 which is
`defined by front transverse member 24 and uppertransverse
`members 60; meanwhile, another eight luminaires 20 are
`mounted or otherwise suspended from the rear-lower planar
`face 74 of frame 14 defined by rear transverse member 26
`and lower transverse member 64. Each luminaire 20 is
`
`mounted to its corresponding cross-memberby the afore-
`mentioned U-shaped mounting bracket 73 (best shown in
`FIG. 1 and 9). As shown in FIGS. 9 and 10, luminaires 20
`are wired through power inlet 70 for providing power
`thereto.
`
`An upper angled face 76 is a plane defined by rear
`transverse member 26 and uppertransverse member 60, and
`is further defined by upper cross-members 46. Likewise, a

`lower angled face 78 is a plane defined by front transverse
`member 24 and lower transverse member64, and is further
`defined by lower cross-members 54. Depending on the
`number of luminaires 20 needed to be mounted to frame 14
`for the desired application, it is contemptated that frame 14
`need not
`include all of the various members disclosed
`herein.
