I N VENTOR United States Patent 3,410,995 UPRIGHT, SECTIONAL, TUBULAR SUPPORT STANDARD James F. Gray, 3717 Cedar Elm, Wichita Falls, Tex. 76308 Filed Feb. 24, 1965, Ser. No. 434,804 15 Claims. (Cl. 240-84) ABSTRACT OF THE DISCLOSURE An upright standard of tubular construction, which may be assembled to present substantially the rigidity of a standard of unitary construction, and may be disassembled and the tubular members of smaller size may be completely telescoped into the larger tubular member and base for shipping and storage. When assembled intoan upright standard, the tubular joints are sealed to present a weather tight construction, which enables electrical wires to be run therethrough, when it is desired to install lighting fixtures street lights or the like, near the upper end of the standard. Provision is made to detachably connect an outstanding, tubular arm intermediate the length of the standard, which arm is in conduit communication with the interior of the upright, tubular standard, to enable wires to pass therethrough in protected relation to a light fixture mounted thereon near the end thereof. Further provision is made to have the arm arcuately rotatable to enable the arm to be moved out of the way of tall objects being moved thereby. Still further provision is made to enable the arm to paravane in event wind pressure exceeds safe limits, which the arm is constructed to withstand.

This invention relates to improvements in lamp posts and more particularly to lamp posts which may be constructed in sectional components and, for the most part, shipped or transported on trucks or stored in telescoped relation as to benefit from lower freight rates due to the compactness of the telescoped unit ready for shipment or which require less room for storage.

Various sectional lamp posts have been proposed heretofore, but these, for the most part were not designed to serve a multiplicity of purposes, which may be telescoped for storage or shipment, but erected for use.

The present lamp post is so constructed that it may be assembled of the desired number of sections and erected to obtain the desired height lamp post, and by the utilization of assembly of components, a variety of lamp post adaptations and modifications is possible.

The present lamp post is so constructed as to form a conduit therethrough, thereby obviating the necessity for exposed wiring or the use'of an additional electrical conduit in which to install the electrical wiring.

Provision is made in the present device to enable multiple uses of the lamp post, as for street lighting or for the supporting of signal lights over the traffic lanes.

Further provisions are made to seal the lamp posts against intrusion of moisture, which would be injurious to the metal of which it is constructed and to the electrical wiring therein.

The present lamp post is also so designed to prevent one section thereof against turning with respect to the other sections thereof.

The lamp post is also constructed with an outstanding arm therein, which arm may be held in fixed relation against turning under normal conditions; however upon exertion of excessive wind pressure on the oustanding arm, the bolts thereof will be sheared, which will permit ice the arm to swing in aligned relation with the direction in which the wind is blowing.

Still another provision of the present device is to provide a lamp post which has an arm to support a light fixture, which arm may be readily arranged so as to rotate through an are, thereby to permit tall structures to pass thereby without the necessity of dismantling the light post, and which arm may be readily swung back into place and secured by bolts in a minimum of time.

An object of this invention is to provide an upright telescoping pole member which may readily assembled and disassembled, and for the most part, the sections may be telescoped together in the minimum of space for shipping, or for storage.

Another object of the invention is to provide a sectional lamp post or the like, which may be readily erected and the sections thereof fixed against relative rotation.

Still another object of the invention is to provide a lamp post having an outstanding arm thereon, which arm will yield at a predetermined wind pressure to obviate damage, but which may be readily and quickly returned to the original position in a minimum of time.

Still another object of the invention is to provide a lamp post having an outstanding arm thereon which may be readily rendered rotatable through a predetermined are when it is desired to move the arm out of the path of a structure or the like so that such structure may be moved thereby.

Still another object of the invention is to provide a lamp post which may be readily secured together in a minimum of time and which will be supported in upright position against windstorms and the like.

Still another object of the invention is to provide a lamp post forming a closed conduit to enable Wiring to be carried therethrough and to the respective lights without the wiring being exterior of the lamp post.

While the present invention, for purposes of illustration and description, has been referred to as a lamp post, it is to be understood that the same construction may be used for street signs or installed for other uses to which it is adapted.

With these objects in mind and others which will become manifest as the description proceeds, reference is to be had to the accompanying drawings in which like reference characters designate like parts in the several views thereof, in which:

FIG. 1 is a side elevational view of the lamp post with parts broken away and shortened and with parts being shown in section, showing a lighting fixture and a signal light, in dashed outline, as installed thereon;

FIG. 8 is an enlarged, fragmentary, elevational view of a joint within the length of the lamp post, with parts being broken away andshown in section to bring out the details of construction;

FIG. 9 is an enlarged perspective View of a support member, shown apart from the lamp post;

FIG. 10 is an enlarged perspective, fragmentary view of a portion of the lower end of one of the tubular members;

FIG. 11 is an elevational view, on a reduced scale,

showing the signal light support arm removed therefrom and showing parts broken away and shortened; and

FIG. l2 is a longitudinal, sectional view of the main body portions of the lamp post telescoped together for shipping, storage or the like, and showing portions thereof in elevation.

With more detailed reference to the drawings the numeral 1 designates generally the lower section or base on which a tubular member 2 is welded and braced by gusset plates 4. The tubular member 2 is securely welded to the upper end of the base 1 which base is shaped like a pyramid or cone, which tubular member is in communication with the hollow portion of base 1 so that underground wiring, which comes into the base 1, may pass upward therethrough and through the tubular member 2. The tubular member 2 has a series of elongated support members 6 at spaced intervals therearound, as will best be seen in FIGS. 6 and 8, which support members each have an elongated shank 8 which has a face 9 thereon which is parallel to the back thereof for a distance sufficient to support the next tubular member therein against material lateral movement.

The lower end of each of the support members 6 has an angular face 10 thereon and when these support members 6 are circumferentially spaced within the tubular member 2, and welded in place, the tubular member 2 is then preferably placed in lathe or boring mill, and the inner faces 9 of shanks 8 are cut to a tolerance size, which is slightly larger than the next succeeding joint of the tubular member 12 to be telescoped thereinto. The tubular member 12 has complementarily, circumferentially milled slots 14 in the lower end, which slots are of a width and depth to seat on the angular face 10 of support m mber 6 and each of the slots 14 has an angular face 16 to fit in complementary relation with angular face 10 on sup port member 6.

The upper end of tubular member 2 has a bushing 18 fitted thereinto in telescoped relation, as will best be seen in FIG. 8, with a portion thereof being adapted to slide thereinto in close fitting relation into the inner diameter thereof. The outer diameter of the bushing 18, above the upper end of the pipe being of the size complementary to the outer diameter of the pipe, which bushing may extend upward and be rounded inward, and be bored by a lathe or boring mill at the same time the inner faces 9 of support member 6 are bored, and with the boring thus performed, as well as the facing of the angular face 10 on support member 6, uniformity of seating of tubular member 12 in slots 14 and on angular faces 16 is assured. It is preferable to have a plurality of set screws 20 screwthreaded through the upper portion of bushing 18, so as to engage tubular member 12 to prevent relative longitudinal movement therebetween. The bushing 18 is welded to tubular member 2 as indicated at 22. The bushing 18 has an O-ring groove 24 therein within the bore thereof in which an O-ring 26 is positioned to form a fluid tight seal between bushing 18 and tubular member 12.

Each of the lamp post sections has a bushing, similar to the bushing 18, secured to the upper end thereof, to join the sections together, as described for the bushing 18 on tubular member 2. Each of the succeeding bushings 18 are of the same construction as the first mentioned bushing and the joints between the tubular members 12 in which the bushing 18 is positioned, and the ends of the tubular members 12 telescoped thereinto are of the same construction.

At the desired height on tubular member 28, which is similar in construction on the lower end to tubular member 12, circumferentially spaced keys 30 are secured thereto, as by welding. A key slotted flange 32 is fitted on keys 30 so that the upper face of the flange will be level or above the upper end of keys 30, whereupon set screws 34 screwthreaded into flange 32 are tightened in secure relation to prevent movement of the flange 32 relative thereto. The flange 32 preferably has a series of holes 36 arranged a spaced distance from the axis thereof to receive bolts 38 therethrough. It is preferable to have these bolts of a predetermined shear strength, as by cutting a groove 40 therein at the point of shear between flange 32 and a flange 42, as will best be seen in FIG. 5. As shown in FIG. 3, four bolts are provided to bolt flanges 32 and 42 together. However, it is preferable to have a multiplicity of holes 36 within flange 32 so the desired angularity of arm 44, with respect to base 1, may be had. While only one arm 44 has been shown and described, it is to be understood that two or more arms may be fitted onto the lamp post and either arranged in opposed relation or in any desired angulated relation.

The arm 44 is composed of an upper tubular member 46 and a lower tubular member 48 which members diverge upwardly and outwardly, with upright spacing elements 50 and 52 welded therebetween to give the proper reinforcement to enable the arm 44 to span a substantial distance. The lower end of tubular member 48 is secured to a sleeve 54, as by welding, which sleeve 54 is secured to the upper face of flange 42 as by welding, with the sleeve 54 and the flange 42 being fitted in rotatable relation around tubular member 28. A sleeve 56 has an apertured plate 58 secured to the upper end thereof, as by welding or the like, which sleeve 56 is fitted over the upper end of tubular member 28 in telescoped relation and is secured to spacing element 50 to support the plate 56 on the sleeve spaced thereabove. The tubular member 46, which serves as an outstanding arm, is secured to the sleeve 56 as by welding in such manner that a hole 60 in sleeve 56 is in register with the hole in tubular member 46 to enable wiring to be passed upward through tubular members 2, 12, 28, whereupon a removable door 62 can be removed and the wire can be directed through hole 60 into tubular member 46 and downward through a slot 64 in the lower side thereof and through the conventional conduit 66 into a signal light 68 or the like. The signal light 68, or other light has the usual weather-proof tubular cup 70 thereon, which covers the wire passing downward through slot 64.

It is to be pointed out that the upper end 57 of tubular member 56 is a spaced distance above the lower end of sleeve 56 to form a weather tight joint between tubular member 28 and sleeve 56. With the sleeve being supported thereabove by the upright spacing element 50, which is welded to the sleeve 56 and to the outstanding tubular member 46, enables wiring to be passed upward thereabove and through :hole 60, in sleeve 56, so that the arm may be rotated 360 degrees or more, without the wire becoming entangled or sheared. The door 62 provides access to the wiring so the wire may be directed upward through opening 72 into tubular member 74, which is secured to the upper face of plate 58, as by bolts 75 passing downward through apertured flange 76 and screwthreaded into plate 58. The upstanding tubular member 74 has a hole 78 therein, which hole is in register with a second outstanding tubular member 80 to form an arm on which a light fixture 82 is supported in a manner similar to signal light 68. An ornamental ball 84 may be provided on the upper end of tubular member 74, which ball has a pin 86 thereon to close and seal the upper end of tubular member 74 after the wires have been directed from tubular member 74 into hole 78 and into tubular member 80 to supply light fixture 82 with electricity. A gusset plate 88 is provided between upstanding tubular member 74 and outstanding tubular member 80 and is welded thereto to support the outstanding tubular member 80 to form an arm to support a light fixture 82.

The light post as shown in FIG. 11 is substantially identical in structure with the light post as shown in FIG. 1, except the flanges 32, 42, and arm 44 have been deleted. A tubular member 28 has a screwthreaded, apertured plate 58a secured on the upper end, to which a plate 76 is secured by bolts 75 on which plate 76 is mounted on outstanding arm 80. Otherwise this form of the invention is substantially the same as the above mentioned form of the invention.
