This application claims priority and the benefit of 35 USC §119(e) to United States patent application Ser. No. 61/955,262 filed 19 Mar. 2014.
SCOPE OF THE INVENTIONThis invention relates to a pole guide tool via which forces can be applied to a suspended pole to assist in locating the pole by manipulating the tool from a location spaced from the pole.
BACKGROUND OF THE INVENTIONInstances arise where a pole such as a hydro pole to be used to support electrical wires is to be hung vertically as suspended from a crane and moved to a location in which the pole is to be secured for use as, for example, impeded within a hole in the ground.
The present inventor has appreciated disadvantages which arise as when a person may attempt to engage the suspended pole with their hands and arms to move the suspended pole, notably, that dangerous situations may arise with the person adjacent to the suspended pole while the pole is being moved.
SUMMARY OF THE INVENTIONAccordingly, to at least partially overcome these disadvantages, this invention provides, in one aspect, a pole guide tool via which forces can be applied to a suspended pole by manipulating the tool from at least a partially spaced location from the pole.
In one aspect, the present invention provides a pole guide tube comprising an elongate tool rod having a distal first end adapted to be engaged by a user and a second end carrying a tool head,
the tool head comprising a split ring defining an opening therethrough,
the split ring including a fixed ring section and a pivoting ring section pivotally mounted to the fixed ring section,
the pivoting ring section spanning between ends of the fixed ring section,
the pivoting ring section pivotally movable between a closed condition and an open condition to permit a pole member to become received within or removed from within the split ring.
Preferably, the fixed ring section has a first end and a second end, the pivoting ring section has a first end and a second end, and the pivoting ring section spans between the first end of the fixed ring section and the second end of the fixed ring section.
Preferably, a latching mechanism is included to latch the pivoting hinge section in the closed condition.
Preferably, the split ring when in the closed condition provides an interior surface via which forces transmitted from the distal first end of the tool rod may be applied to a pole passing through the opening to urge the pole away from a user holding the distal first end of the tool rod or to urge the pole towards a user holding the distal first end of the tool rod.
In another aspect, the present invention provides a method of guiding an elongate pole having an upper end and a lower end and which poles is supported to hang downwardly from its upper end,
the method comprising providing a pole guide tool having an elongate tool rod with a distal first end and a second end, with the second end carrying a tool head,
the tool head having an opening passing therethrough sized to permit the pole to pass freely through the opening without engaging the tool head,
the method comprising locating the tool head to extend circumferentially about the pole,
lowering the pole axially through the tool head and applying forces from the first distal end of the tool rod to the pole by engagement of interior surfaces of the tool head about the opening with side surfaces of the pole by manipulating the distal end of the tool rod from a location spaced laterally from the pole.
Further aspects and advantages of the present invention will become apparent from the following description taken together with the accompanying drawings in which:
Referring to
A hinge structure 40 connects the first end 23 of the fixed ring section 22 to the first end 33 of the pivoting ring section 32 for pivoting about a hinge axis 41. The hinge structure 40 includes a fixed bracket 42 fixedly secured to the first end 23 of the fixed ring section 22 and a pivoting hinge bracket 43 fixedly connected to the first end 33 of the pivoting ring section 32. A hinge pin 44 passes coaxially about the hinge axis through coaxially aligned openings in each of the hinge brackets 42 and 43.
A latch structure 50 releasably couples the second end 24 of the fixed ring section 22 to the second end 34 of the pivoting ring section 32. The latch structure 50 has a fixed latch bracket 51 secured to the second end 24 of the fixed ring section 22 and a pivoting latch bracket 53 fixed to the second end 34 of the pivoting ring section 32. As seen in
The fixed ring section 22 and the pivoting ring section 32 preferably are each formed from a tube, preferably of metal, or a rod which is bent into the desired shape so as together form a two piece circular split ring which is disposed in a flat plane which is normal to the axis 41 of the hinge structure 40. Preferably, as well, each of the openings 53 and 54 through the latch structure 50 is also coaxial about a latch axis perpendicular to the plane although this is not necessary.
With the lynch pin 55 removed, the pivoting ring section 32 may be pivoted about the hinge axis 41 relative the fixed ring section 22 between a closed condition shown in
The particular nature of the lynch pin 55 is not critical, however, preferably, the lynch pin 55 has an enlarged head 56 which can readily be grasped and engaged manually by a workman using the tool 10 as, for example, under extreme winter conditions as with thick insulated mittens or gloves. Preferably, the head 56 of the lynch pin 55 may be relatively enlarged or carry a loop for easy engagement. Preferably, the lynch pin 55 may be tethered to the tool head 14 preferably by being secured by a flexible strap or wire 57 shown only on
Preferably, the lynch pin 55 includes the head 56 for engagement by a hydro linesman manually and a shaft 58 which extends from the head 56 and is sized to pass through the openings 53 and 54. The lynch pin 55 preferably may include a catch member which will engage the free end of the shaft away from the head in a frictional manner to prevent the lynch pin 55 from becoming disengaged from the latch brackets other than when not an insubstantial manual axial force is applied to the lynch pin 55.
Referring to
The inside diameter of interior surfaces 71 of the closed split ring 20 is selected to be larger than a largest diameter of the pole 70 to be guided. With the pole 70 passing through the closed split ring 20, a hydro linesman may, by engaging a distal end 60 of the tool rod 12, apply forces to the tool rod 12 which will be transmitted to the pole 70 within the split ring 20 as, for example, to push the pole away from the linesman or to pull the pole towards the linesman.
To assist in guiding the pole 70 in movement downwardly through and below the wires and into the hole in the ground, in
Preferably, for initial engagement of the split ring 20 about the pole, with the pole 70 held in a relatively safe and stable position by the crane 78, the linesman 85 within the bucket 84 may manipulate the bucket 84 to be horizontally close enough to the pole 70 that the linesman 85 can manually engage and disengage the lynch pin 55 for locking and unlocking and coupling and uncoupling of the split ring 20 about the pole.
Preferably, with the lynch pin 55 removed, the linesman 87 may hold the tool rod 12 in an orientation that will have the pivoting ring section 32 either pivot about the axis 41 from the closed condition to the open condition or from the open condition to the closed condition due to the weight of the pivoting ring section 32 and its relative position to the axis 41. For example, with the lynch pin 55 removed and the split ring 20 in the closed condition, if the plane of the split ring 20 is tipped such that the pivoting ring section 32 is lower than the fixed ring section 22, there will be a tendency of the pivoting ring section 32 to pivot towards the open condition.
The pole guide tool 10 shown in
The tool head 14 preferably has a split ring 20 as illustrated in preferred embodiments, however, various other arrangements could be provided. Preferably, the tool head 14 extends about the circumference of the pole and does not prevent axial movement of the pole relative to the tool head 14.
Preferably, the tool head may be formed from metal, more preferably, from aluminum tubing, however, any materials or combination of materials may be used. The tool rod 12 preferably is adapted to not conduct electricity and may be preferably made from plastic or carbon fiber materials although metal could be used or any combination.
Many different variations and modifications of tool heads will now occur to persons skilled in the art. For a definition of the invention, reference is made to the following claims.
