Abstract
An apparatus for reinforcing an upstanding utility/meter pole having a worn top includes an elongate brace adapted to bear against the pole near a top end of the pole. A washer plate is disposed in overlying relation to the elongate brace. A front support is secured to an opposite side of the pole by an elongate bolt that extends diametrically through the pole and is engaged by a nut to secure the brace and front support in sandwiching relation to the pole. A second embodiment reinforces a cross arm of a pole and a third embodiment ensleeves a pole at its uppermost end in a cylindrical body that serves as a prosthesis for a disintegrating pole top.
Description
- 1. Field of the Invention
- This invention relates, generally, to repair of upstanding poles such as utility poles.
- More particularly, it relates to methods and apparatuses for strengthening the tops of poles that have structurally deteriorated over time to avoid or delay the cost of replacing such poles.
- 2. Description of the Prior Art
- Utility poles become degraded over time near the ground and also at their upper end. There are many patented devices for strengthening such poles at or near the ground so that they don't fall over but there has been little inventive activity for strengthening the upper end of such poles to which are connected dedicated voltage transmission/distribution lines as well as telephone/CATV lines.
- Meter poles are smaller versions of utility poles; they are positioned near structures such as mobile homes where laws forbid the direct attachment of permanent lines. As used herein, the term “pole” refers to utility as well as meter poles or any other type of pole that may be in need of upper end reinforcement.
- The current cost of replacing a utility pole that has lost its structural integrity is about three thousand dollars per pole. Every U.S. state has millions of such poles. There are between one hundred thirty to one hundred eighty million utility poles in use in North America and most utility companies replace about six thousand poles per year. The cost of course is passed along to the consumer.
- The upper ends of many pressure-treated poles that were installed in the decade of the 1970s are now losing their structural integrity and are in need of replacement. The same will of course hold true in the future of poles installed in later decades as well. However, it would save companies and consumers substantial monies if those poles could be reinforced instead of replaced.
- However, in view of the art considered as a whole at the time the present invention was made, it was not obvious to those of ordinary skill in the art how the upper ends of such poles could be reinforced at a cost substantially less than pole-replacement costs.
- The long-standing but heretofore unfulfilled need for a device that reinforces deteriorating utility poles, meter poles, and the like is now met by a new, useful, and non-obvious invention.
- The inventive structure is an apparatus for reinforcing an upstanding pole having an upper end that is worn, rotted, damaged, or otherwise in a deteriorated state.
- The novel structure includes an elongate brace and at least two bolt-accommodating openings formed in the elongate brace. Each bolt-accommodating opening is centered on a longitudinal axis of symmetry of the elongate brace. The elongate brace is adapted to bear against the upstanding pole near the worn upper end of the upstanding pole.
- At least two washer plates are disposed in overlying relation to the elongate brace and a bolt-accommodating opening is formed in each washer plate. The bolt-accommodating opening is centered on a longitudinal axis of symmetry of each washer plate and is aligned with a bolt-receiving opening formed in the elongate brace.
- At least two elongate bolts are adapted to extend diametrically through the upstanding pole. Each elongate bolt extends through a preselected bolt-accommodating opening formed in the elongate brace and through the bolt-accommodating opening formed in the associated washer plate.
- Each elongate bolt has a tool-engageable head and a free end that extends outwardly from the upstanding pole diametrically opposite from the tool-engageable head. A nut screw-threadedly engages the free end of each elongate bolt and advancement of the nut increasingly secures the associated washer plate to the elongate brace and therefore increasingly secures the elongate brace to the upstanding pole so that the upper end of the upstanding pole is reinforced by the elongate brace.
- The elongate brace has a base and a pair of laterally spaced apart legs are formed integrally with the base. The legs are adapted to bear against the upstanding pole.
- At least one cavity for accommodating a pre-existing, conventional washer is formed in the elongate brace in open communication with each bolt-accommodating opening. Each elongate bolt extends through the conventional washer-accommodating opening when the nut secures said washer plate to said elongate brace.
- In a second embodiment, each washer plate has a recessed channel formed therein, centered on the longitudinal axis of symmetry of the washer plate. The recessed channel extends into an associated bolt-receiving opening and a spring lock is disposed in overlying relation to a bottom wall of the recessed channel. A nut screw-threadedly engages the free end of the elongate bolt in bearing relation to the spring lock so that advancing the nut increasingly urges the washer plate towards the elongate brace and therefore increasingly presses the elongate brace against the upper end of the upstanding pole.
- In a third embodiment, each washer plate has a raised ridge formed therein, centered on the longitudinal axis of symmetry of the washer plate, said longitudinal axis of symmetry being coincident with the longitudinal axis of symmetry of the elongate brace.
- In the third embodiment, a first spring lock is disposed in each bolt-accommodating opening formed in the elongate brace and a first nut is screw-threadedly engaged to the free end of the elongate bolt in bearing relation to the first spring lock. The elongate ridge is disposed in overlying relation to the first nut and a second spring lock is disposed in overlying relation to the elongate ridge. A second nut screw-threadedly engages the free end of the elongate bolt in bearing engagement to the second spring lock so that advancement of the first and second nuts enables each washer plate to bear increasingly against the elongate brace and thus cause the elongate brace to bear increasingly against the upper end of the pole, thereby reinforcing it.
- All three embodiments include an elongate front support member that is arcuate in transverse section to conform to the surface of the pole and which is mounted on the upper end of the pole in diametric relation to the elongate brace so that the damaged upper end of the upstanding pole is sandwiched between the front support member and the elongate brace.
- At least two openings are formed in the front support member to accommodate the elongate bolts that secure the front support member to the upstanding pole. The elongate bolt that extends through the elongate brace and washer plate is the same elongate bolt that extends through the preselected opening formed in the front support member, i.e., the elongate bolts secure the front support member to a first side of the pole and secure the elongate brace to a second, diametrically opposed side of the pole so that the upper end of the pole is sandwiched between the front support member and the elongate brace.
- A fourth embodiment of the invention is an apparatus for supporting a horizontally disposed cross arm mounted to an upstanding pole. It includes a first vertical part that is adapted to be secured to the pole and a horizontal part formed integrally with the first vertical part at an upper end of the first part.
- The horizontal part extends away from the pole and has a depth substantially equal to a depth of the cross arm.
- A second vertical part is formed integrally with the horizontal part at a free end of the horizontal part and projects upwardly therefrom.
- The horizontal part is adapted to abut and support a bottom wall of the cross bar and the second vertical part is adapted to abut a front wall of the cross bar to prevent rotation of the cross bar in a horizontal plane about a longitudinal axis of the pole.
- An elongate brace is adapted to abut the pole in diametrically opposed relation to the cross arm support member and an aperture is formed in the first vertical part of the cross arm support member to receive a bolt that extends diametrically through the pole to secure the first vertical part and hence the cross arm support member to the pole.
- A fifth embodiment of the invention is a prosthetic apparatus for reinforcing a deteriorating top of an upstanding pole. It includes a cylindrical main body having an upper rim at a first end of the main body. A pair of legs depend from a second end of the main body in diametrically opposed relation to one another.
- A plurality of apertures is formed in the cylindrical main body in circumferentially and longitudinally spaced relation to one another to facilitate attachment of the cylindrical main body and the legs to the pole.
- The upper rim projects above an uppermost end of the upstanding pole when the uppermost end is ensleeved by the cylindrical main body.
- A top cap has a skirt having a length substantially equal to a distance of the upper rim above the uppermost end of the upstanding pole so that the skirt fits within the hollow interior of the cylindrical main body when the top cap engages the cylindrical main body.
- A general object of this invention is to lengthen the lifetime of upstanding poles such as a utility poles owned by a public or private utility company or meter poles of the type used in connection with mobile homes.
- A more specific object is to reinforce the upper end of such poles at a cost that is much less than the cost of replacing such a pole.
- These and other important objects, advantages, and features of the invention will become clear as this disclosure proceeds.
- The invention accordingly comprises the features of construction, combination of elements, and arrangement of parts that will be exemplified in the disclosure set forth hereinafter and the scope of the invention will be indicated in the claims.

elongate brace 24 andwasher plates 32 are depicted in perspective view inFIGS. 1A and 3 .Openings 28 are provided in plural locations in both circular and slotted form to accommodate various pole structures.Open slots 28 a at the opposite ends ofelongate brace 24 are used to accommodate pre-existing bolts as needed. - It will be observed in the embodiment of
FIG. 2A that eachnut 34 is provided at the time of pole repair, i.e.,conventional nut 22 remains in its original position. - Novel
front support 18, depicted inFIGS. 1A , 1B, and 4 has an elongate structure. It has a first end that underliesinsulator 14 and a second end that is longitudinally spaced apart from the first end and which therefore does not underlie the insulator. -
Front support 18 is arcuate in transverse section and its upper end is slotted as at 18 a to accommodateelongate bolt 16 which is not depicted inFIG. 4 . Circular or slottedopenings 18 b are formed therein as depicted to accommodate bolts as needed for fasteningfront support 18 to the front or insulator side ofpole 12. -
Front support 18 andelongate brace 24, which provides back support, are disposed in diametrically opposed relation to one another and holdpole 12 in sandwiched relation between them. -
FIG. 2B depicts a second embodiment whereconventional nut 22 is removed frombolt 16 and then re-engaged thereto. In this second embodiment, eachwasher plate 32 has a recessedchannel 32 a formed in the center thereof as depicted.Channel 32 a includes centrally-apertured bottom wall 32 b and said bottom wall is substantially flush with washer-accommodatingopening 30.Bottom wall 32 b thus performs the function of a washer and reinforcesconventional washer 20 - Each
spring lock 36 fits withinchannel 32 a and abutschannel bottom plate 32 bConventional nut 22 is returned to its screw-threaded engagement withbolt 16 to bear againstspring lock 36. This second embodiment has the advantage of not requiringsecond nut 34 of the first embodiment. -
FIG. 2C depicts a third embodiment whereconventional nut 22 remains as in the first embodiment in screw-threaded engagement withbolt 16, and whereadditional nut 34 of the first embodiment is also used. - In this third embodiment, each
washer plate 32 has a raisedridge 33 that includes centrally-aperturedtop wall 33 a as depicted inFIG. 2C .Conventional nut 22 andspring lock 36 are disposed in bearing relation toconventional washer 20. Eachwasher plate 32 is then placed into overlying relation tobase 26 ofelongate brace 24 in registration with each opening 28 as needed. Asecond spring lock 38 is placed into overlying relation to eachtop wall 33 a and is secured thereto by anut 34. - A fourth embodiment is depicted in
FIGS. 5A , 5B, and 6. This embodiment has utility in connection withupstanding poles 12 having across arm 44, with or withoutbraces 44 a. The perspective view ofFIG. 6 depicts crossarm support member 46. Aperture 48 is formed in firstvertical part 50 and may take the form of a circular opening or an elongated slot as depicted. A first ninety degree bend forms horizontal part 52 and a second ninety degree bend forms secondvertical part 54 which serves as a detent. - As depicted in
FIG. 5A ,bolt 56 is inserted intopole 12 through aperture 48 to securecross arm support 46 to said pole.Cross arm support 46 is positioned onpole 12 so that horizontal part 52 serves as a support surface forcross arm 44 at the mid-length region of said cross arm. Horizontal support surface 52 has a depth substantially equal to a depth ofcross arm 44 so thatdetent 54 overlies a front surface ofcross arm 44 at least to some extent. Horizontal support surface 52 provides support forcross arm 44 and inhibits rotation of said cross arm in a vertical plane anddetent 54 holdscross arm 44 so that said cross arm cannot rotate in a horizontal plane about the vertical axis ofpole 12. - As depicted in
FIG. 5B , bolt 56 which securescross arm support 46 topole 12 preferably extends diametrically through the pole and when used with a suitable nut and washer secureselongate brace 58 to the rear side ofpole 12. Further bolts may be used to further secure saidelongate brace 58 topole 12, saidbrace 58 being provided with multiple apertures along its extent and slots at its opposite ends for that purpose. The sandwiching ofpole 12 betweencross arm support 46 andelongate brace 58 provides a heretofore unknown degree of support to crossarm 44. - A fifth embodiment is depicted in
FIGS. 7 , 8A and 8B.Main body 62 ofbrace 60 is cylindrical.Legs main body 62 in diametrically opposed relation to one another. The upper rim ofmain body 62 is denoted 62 a. Apertures collectively denoted 63 are formed in cylindricalmain body 62 in circumferentially and longitudinally spaced relation to one another and apertures collectively denoted 65 are formed inlegs - As depicted in
FIG. 8A ,upper rim 62 a of cylindricalmain body 62 projects above theuppermost end 12 a ofpole 12 whenbrace 60 is properly installed in ensleeving relation to a pole top.Skirt 66 oftop cap 68 has a length equal to or just slightly less than the distance ofrim 62 a above pole top 12A so that said skirt fits within the hollow interior of cylindricalmain body 62 whentop cap 68 is in its functional position as depicted inFIG. 8B . The diameter ofskirt 66 causes it to fit tightly with a good friction fit within said hollow interior so that high winds cannot cause it to separate from said functional position. Various bolts or screws extend throughapertures brace 60 topole 12. - It will thus be seen that the objects set forth above, and those made apparent from the foregoing disclosure, are efficiently attained and since certain changes may be made in the above construction without departing from the scope of the invention, it is intended that all matters contained in the foregoing disclosure or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
- It is also to be understood that the following claims are intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention that, as a matter of language, might be said to fall therebetween.
