OUTDOOR LIGHTING FIXTURES Filed May 1, i962 Patented Sept. 17, 1963 Calif.

Filed May 1, 1962, fies. No. 191,578 7 Claims. (Cl. 240-425) The invention relates to the lighting art and par ticularly to a unique outdoorlighting fixture arrangement.

Those familiar with current developments in the outdoor lighting field will understand that many commercial requirements dictate a high degree of illumination be provided in specific areas. For example, it has been found that appropriate local high intensity illumination has a marked effect on improved sales in, for example, automobile sales businesses, service stations, shopping centers, vehicle parking areas of all types, as well as freight terminals of both the trucking type and railroad type. The results of proper illumination form the standpoint of increased sales and increased efficiency of operating personnel and the like has been frequenly demonstrated. Giving attention to this facet of normal business operation, it will be readily understood that the lighting fixtures employed should desirably meet certain functional requirements. Initially, the fixture should be of such design and construction so as to be electrically sound. That is to say, in view of the fact that the fixture is an outdoor fixture, the wiring and electrically operating parts reasonably should be adequately shielded from all climatic conditions. Additionally, the fixture arrangement should be of such design and construction as to offer flexibility to meet varied illumination requirements of a particular user. For example, in a given installation, it may be desirable at a certain point to vary the total amount of illumination available or to change its direction and thereby have the effect of highlighting a particular area of the total area to be illuminated. The advantage of such flexibility in many commercial operations will be obvious as, for example, in the sale of automotive vehicles, it may be desirable at a given point in time to spotlight a given vehicle or vehicles and thereby enhance the possibility of attracting customer attention. Additionally, the fixture should be of such construction so as to afford a pleasing apearance and, as a result of its functional characteristics, meet the requirements of modern design. It has further been found that a desirable lighting fixture structure reasonably will possess simplicity in construction and economy in initial cost.

The herein disclosed invention meets all of the requirements mentioned above and more. Initially, the invention comprehends a basic mounting unit which is selectably adaptable to a wide variety of fixture constructions. Thus, a high degree of concentrated illumination may be provided in a variety of applications. The structure is electrically sound and possesses a simplicity of construction which is not only ornamental in appearance but additionally offers a high degree of flexibility to the user.

The specific construction and other features of the invention will be apparent from an examination of the following specification and the associated drawings, wherein:

FIGURES 8 to 11, inclusive, are perspective views of modifications of the mounting disclosed in FIGURE 7; and

FIGURE 12 is a central vertical, partially sectioned view of the structure illustrated in FIGURE 7.

' Describing the invention in detail, attention is initially directed to FIGURES 7 and 12. It will be understood that a base member is indicated generally at 2. In the preferred embodiment of the invention, said base member comprises an elongated, generally cylindrical pipe-like element which has one end (not shown) which may be adapted for mounting on the ground surface or other fixed location in any conventional manner. The base member 2 comprises the entire support for the typical arrangement herein illustrated. While the base member is here shown to be a cylindrical pipe, it will be understood that a variety of configurations may be employed such as rectangular or other geometric form and still fulfill the functional requirements of the disclosed invention. A fixture supporting element is indicated generally at 4 and in the preferred embodiment comprises a cylindrical pipe 6 having an inner diameter of such dimension so as to telescopically receive the upper end of the base member 2. Again, the cylindrical characteristics of the pipe 6 represent only a preferred embodiment of the invention, it being understood that any geometric configuration may be used so long as the design employed bears a concurrent relationship in the base member 2.

The pipe or element 6, as specifically shown in FIG- U-RE I2, telescopically receives the upper end of the base member 2 and is provided with locking means such as the set screws 8, 8 which are threadably received in the pipe 6 and, by manual manipulation, fixedly secure the pipe 6 to the base member 2. It will be noted that the pipe 6 may be rotatably positioned on the base member 2 in a virtual infinite number of positions thereon within the 360 arc of the base member 2. In addition, the cylindrical pipe 6 is provided with a plurality of fixture supporting horn elements 10, 10, said fixture supporting elements in the preferred embodiment constituting pipes of truncated J form having their lower ends received within the appropriate apertures 12, 12 within the pipe 6. To fixedly secure the elements 10 to the pipe 6, the lower ends of the latter may be welded as at '14, 14 or secured thereto in any other conventional manner. To add stability to each element 10, the preferred embodiment employs supporting bars 16, 16 having opposed ends secured in any conventional manner as, for example, by welding at 18, 18 to intermediate portions of the element 10 and the carrying pipe 6.

While accurate location of the cylindrical pipe 6 on the supporting member 2 may be achieved in a variety of ways, the preferred embodiment dictates that the lower inner ends 20, 20 of the elements 10 project inwardly of the pipe 6 to overlie the upper edge of the base member 2 and provide an effective abutment for engagement by the upper end of said base member. It will thus be understood that a proper physical relationship is thereby established between the hollow base member 2, the hollow pipe member 6, and the hollow elements 10. An appropriate cap 22 may be congruently sized to overlie the upper end of the pipe member 6, said cap 22 having a peripheral flange 24 therearound which receives the upper end of the pipe member 6 and effectively seals said open end in addition to providing locking means as, for example, the set screw to physically secure the cap 22 to the pipe member 6. It will be readily apparent to those skilled in the art that with the arrangement ust described, electrical wiring for the lighting fixture hereinafter referred to will be trained through the hollow base member 2, the hollow cylindrical pipe 6, and the hollow supporting elements 10. Thus, the wiring is eifectively shielded, by the structure described and the cooperating function of the cap 22, from all climatic conditions rendering the structure highly practical from the standpoint of outdoor lighting.

It will be understood that the supporting elements 10 are here illustrated in vertical relation to the horizontal. However, the structure shown is a preferred embodiment of the invention and it will be understood that the supporting elements 10 may be positioned in any angular relation to the horizontal and still meet the functional requirements of the disclosed invention.

Each of the supporting elements It) is adapted to be telescopically received within one end of connectors 26, 26; each connector 26 additionally is provided with a lower set screw 28 or other suitable connecting means whereby the connector 26 may be fixedly secured to the upper end of the related supporting element 10 and in any angular position thereon. The upper segments of each connector 26 are adapted to telescopically receive one end of a connecting pipe 30. The connecting pipe 30, in the preferred embodiment, may be bent as at 32 adjacent its lower end, said bent portion 32 being received within the connector 26 and again secured thereto in any desired angular position thereon by virtue of any conventional securing means such as the set screws 34.

Leaving the above described structure, attention is now directed to the typical fixture illustrated in FIGURE 1 and indicated generally at 36. it will be understood that the fixture 36 comprises an outer housing 38 of openended, box-like construction and carrying adjacent its inner upper surface a supporting plate 40. The supporting plate 40 may be secured to the housing 38 in any conventional manner as, for example, by bolting. The plate 40 mounts a conventional lighting fixture 42 which includes a fluorescent lighting tube 44. Adjacent one end of the housing 42, an end wall 46 is provided, said end wall 46 having an aperture 48 therein, said aperture being in registering communication with a cylindrical tube 50. The tube 50 is secured to the housing 36 in any conventional manner as, for example, by the spaced supporting plates 52, 52. Additionally, the tube 50 is provided with locking set screws 54, 54, the purpose of which will be hereafter described. Further considering the lighting fixture 36, it will be understood that the tube 50 is dimensioned so that it may, for example, telescopic-ally receive the outer end of one of the connecting pipes It will thus be understood that the fixture may be carried on the end of the pipe 30 and in angular relation to the horizontal. Obviously, the set screws 54- will accommodate fixed mounting of the fixture 36 to the connecting pipe 30 which, by virtue of the cylindrical construction of the pipe 30, as well as the tube 50, the fixture may be rotated on the pipe 30 at any desired angle.

With the above structure in mind, it will be apparent that a high degree of flexibility is provided within the lighting fixture generally, it being noted that the pipe 6 is securable to the supporting member 20 in any angular relation thereon, that a further swivel or rotatable connection is provided by virtue of the connector 26 and its telescopically interfitting relation with the element 10 and pipe 30, and that additionally, a further swivel or variable connection is provided by virtue of the telescopic swivel connection between the pipe 50 and the outer end of the pipe 30.

To provide additoinal flexibility to the lighting fixture arrangement, as well as to accommodate a wide variety of lighting fixtures per se, it may be desirable in some applications to provide an additional connector 60 which may be mounted in telescopic interfittlng relatlonship with the outer end of pipe 30. The connector 60 may be angled as at 62 as desired by the particular installatlon, and additionally may be provided with conventional locking means such as set screw 54 to fixedly secure the connector to the outer end of the related pipe 30. A fixture supporting pipe 66 may be optionally telescopically fitted into the connector 64 and may be secured thereto in any conventional manner as, for example, by welding as at 68. The pipe 66 then may serve as a mounting for the typical fixture 36 illustrated in FIGURE 1 and in the manner earlier described.

Directing attention to FIGURES 4 to 6, inclusive, it will be understood that they illustrate alternate lighting fixture arrangements which may be employed. The lighting fixtures of FIGURES 4 to 6, inclusive, differ little functionally from that described with reference to FIG- URE 1 except that a variety of mounting pipes 70, 72, and 74 may be provided which, in turn, are readily adaptable to the structure described with reference to FIGURES 7 to 12, inclusive. For example, the fixture supporting element 66 associated with the connector 60 may be optionally removed and the pipe 70 of the fixture shown in FIGURE 4 may be mounted in the connector 60 to provide appropriate support for said fixture. In a similar manner, the pipe 72 of the fixture shown in FIGURE 5 may mso be so mounted. Alternately, the supporting pipe 70 in the fixture shown in FIGURE 6 may be mounted in the connector 60 or, if desired, may be physically associated with the connector 26, it being understood that the pipe is then not utilized in the arrangement. From the description given, it will be apparent that the disclosed structure provides a high degree of flexibility in the variable mounting of appropriate lighting fixtures. The unique result of this flexibility is that the arrangement is therefore readily adaptable to the particular users requirements under a wide range of commercial applications.

In addition to the flexibility described above, further flexibility in design and function is provided by the structures illustrated in FIGURES 8 to 11, inclusive. Considering FIGURE 8, it will be noted that the cylindrical pipe 6a is provided with a single mounting element 10a. The structure of FIGURE 9, on the other hand, duplicates the structures of FIGURES 7 and 12 in that two mounting elements 10a are provided and preferably ar ranged in opposed relationship to each other. Alternately, the structure of FIGURE 10 provides three mounting elements 10a, the latter being arranged in equal angular relationship to each other. Still a further modification is illustrated by FIGURE 11 in that four mounting elements 10a are provided, said mounting elements 10a here illustrated in relationship to each other. The disclosure thus illustrates the fact that the particular invention may be utilized to support a plurality of lighting fixtures and, while the mounting elements 10a are illustrated in equi-angular relationship to each other, it will be understood that any number of mounting elements of any angular spacing therebetween may be employed as the dictates of any installation may require.

The invention as shown is by way of illustration and not limitation and may be subject to modification without departing from the scope of the appended claims.
