BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates generally to hand and hoist-line implements.
2. Description of the Related Art
It is often necessary for a person, such as an electrician, to hoist an object to a height that the electrician cannot reach. For example, an electrician's pole can be used to hoist a screw to a ceiling, wherein the screw is threaded into the ceiling using the pole. One type of electrician's pole is often referred to as a Lagmaster Pole, and it can be used to hoist many different types of objects, such as a wire, threaded and smooth rods, a jack chain and a J-hook. One problem with the available electrician's poles is that they are expensive and limited in size and strength.

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a perspective view of various embodiments of a pole assembly, denoted as pole assemblies 100a and 100b. In these embodiments, pole assemblies 100a and 100b are operatively coupled to a drill 101 through a drill chuck 102. Pole assemblies 100a and 100b rotate in response to the rotation of drill chuck 102. Pole assemblies 100a and 100b are used to hoist a fastener 107 so it can be extending through a surface 104 and fastened to a ceiling 103.
In this embodiment, pole assembly 100a includes a conduit 110, and a chuck 130 and socket piece 140 coupled to opposed proximal and distal ends 110a and 110b of conduit 110. Proximal end 110a is coupled to drill chuck 102, and distal end 110b is positioned away from drill chuck 102.
Fastener 107 can be of many different types of fasteners. FIGS. 2a and 2b are perspective views of wood and concrete fasteners 108 and 109, respectively. Wood fastener 108 includes a head 108a and a threaded shaft 108b extending therefrom. Wood fastener 108 is designed to be fastened to wood, such as when ceiling 103 includes wood and surface 104 corresponds to a wood surface. Concrete fastener 109 is designed to be fastened to concrete, such as when ceiling 103 includes concrete and surface 104 corresponds to a concrete surface. It should be noted that fastener 107 can be many other different types of objects, such as a wire, threaded and smooth rods, a jack chain and a J-hook.
FIG. 3 is a perspective view of conduit 110. Conduit 110 can be of many different types, such as electrical conduit used to protect and route electrical wiring. In this embodiment, conduit 110 includes a conduit body 111 with a conduit body channel 113 extending therethrough. Conduit body channel 113 extends between a proximal conduit body opening 112a and distal conduit body opening 112b. Proximal conduit body opening 112a and distal conduit body opening 112b are positioned at proximal end 110a and distal end 110b, respectively, of conduit 110. Conduit 110 can be coupled to chuck 130 and socket piece 140 in many different ways, one of which will be discussed in more detail presently.
It should be noted that pole assembly 100b of FIG. 1 includes a conduit 115, which can be the same or similar to conduit 110. In some embodiments conduits 110 and 115 have the same lengths and, in other embodiments, conduits 110 and 115 have different lengths. Conduit 115 includes a conduit body 116 with a conduit body channel extending therethrough. The conduit body channel extends between a proximate conduit end 115a and distal conduit end 115b.
FIG. 4a is a perspective view of a template 120 used to form a fastener opening at a desired location, such as with conduit 110. FIG. 4b is a cut-away perspective view of template 120 taken along a cut-line 4b-4b of FIG. 4a, and FIG. 4c is a cut-away perspective view of template 120 taken along a cut-line 4c-4c of FIG. 4a.
In this embodiment, template 120 includes a template body 121, and proximal template body opening 122a and distal template body opening 122b at opposed ends. A template body channel 123a extends through template body 121 and between template body opening 122a and a template stop piece 124. A template body channel 123b extends through template body 121 and between template body opening 122b and template stop piece 124. A distance between template body opening 122b and template stop piece 124 is denoted as distance D1 in FIGS. 4a and 4b.
Template 120 includes opposed fastener openings 125a and 125b, which extend through template body 121. Fastener openings 125a and 125b are positioned opposed to each other, as shown in FIG. 4c, so that an object, such as a fastener, can be extended through them. A distance between stop piece 124 and a bottom portion of fastener opening 125a is denoted as distance D2 in FIG. 4a. Further, a distance between stop piece 124 and a bottom portion of fastener opening 125b is denoted as distance D2 in FIG. 4b. In this way, the bottom portions of fastener openings 125a and 125b are positioned the same distance from stop piece 124.
FIGS. 5a, 5b and 5c are perspective views of conduit fastener openings 117a and 117b (FIG. 5c) being formed through proximal end 110a of the conduit 110 of FIG. 2 using template 120 of FIGS. 4a-4c. Conduit fastener openings 117a and 117b are used to couple proximal end 110a of conduit 110 to another piece, such as chuck 130. In operation, proximal end 110a is moved through template body opening 122b and template body channel 123b so it engages template stop piece 124. As mentioned above, the distance between template body opening 122b and template stop piece 124 is distance D1. Hence, a length of conduit 110 which extends through template body channel 123b corresponds to distance D1. A drill bit (not shown) is extended through fastener openings 125a and 125b and proximal end 110a of conduit 110 to form conduit fastener openings 117a and 117b (FIG. 5c), wherein a bottom portion of conduit fastener openings 117a and 117b are positioned distance D1 from proximal conduit body opening 112a. In this way, conduit fastener openings 117a and 117b are formed at a desired location with conduit 110. It should be noted that template 120 typically includes a hardened metal material, such as tool steel, so that fastener openings 125a and 125b resist being worn out in response to extending the drill bit therethrough.
FIGS. 6a, 6b and 6c are perspective views of conduit fastener openings 118a and 118b (FIG. 6c) being, formed through distal end 110b of the conduit 110 of FIG. 2 using template 120 of FIGS. 4a-4c. Conduit fastener openings 118a and 118b are used to couple distal end 110b of conduit 110 to another piece, such as socket piece 140. In operation, distal end 110b is moved through template body opening 122b and template body channel 123b so it engages template stop piece 124. As mentioned above, the distance between template body opening 122b and template stop piece 124 is distance D1. Hence, a length of conduit 110 which extends through template body channel 123b corresponds to distance D1. A drill bit (not shown) is extended through fastener openings 125a and 125b and distal end 110b of conduit 110 to form conduit fastener openings 118a and 118b (FIG. 6c), wherein a bottom portion of conduit fastener openings 118a and 118b are positioned distance D1 from distal conduit body opening 112b. In this way, conduit fastener openings 118a and 118b are formed at a desired location with conduit 110.
FIG. 7a is a perspective view of one embodiment of chuck 130, which is used to couple conduit 120 of FIGS. 5a-5c and FIGS. 6a-6c to drill 101, as shown in FIG. 1.

In this embodiment, chuck 130 includes a chuck body 131, and a distal chuck body opening 132b at one end. Distal chuck body opening 132b is sized and shaped to receive proximate conduit end 110a of conduit 110. A chuck body channel 133 extends through chuck body 131 and between distal chuck body opening 132b and a chuck stop piece 134. Chuck 130 includes a shank 136 which extends away from distal chuck body opening, 132b and chuck stop piece 134. Shank 136 is extended through the drill chuck 102 of drill 101, as shown in FIG. 1.
Chuck 130 includes opposed fastener openings 135a and 135b, which extend through chuck body 131. Fastener openings 135a and 135b are positioned opposed to each other, as shown in FIG. 7c, so that an object, such as a fastener, can be extended through them. Further, fastener openings 135a and 135b are positioned so that conduit fastener openings 117a and 117b are aligned with fastener openings 135a and 135b, respectively, when proximate conduit end 110a of conduit 110 is extended through distal chuck body opening 132b. In this way, a fastener (not shown) can be extended through fastener openings 135a and 135b and conduit fastener openings 117a and 117b so that chuck 130 and proximate conduit end 110a of conduit 110 are coupled together, as shown in FIG. 1.
FIG. 8a is a perspective view of one embodiment of socket piece 140, which is used to couple fastener 107 to conduit 110 of FIGS. 5a-5c and FIGS. 6a-6c, as shown in FIG. 1.

In this embodiment, socket piece 140 includes a socket piece body 141 having a conduit fitting body 141a and socket fitting body 141b. An unsocketed body opening 142a extends through conduit fitting body 141a, and an unsocketed body channel 143a extends through conduit fitting body 141a and between unsocketed body opening 142a and a socket stop piece 144. Unsocketed body opening 142a is sized and shaped to receive distal conduit end 110b of conduit 110. Body channel 143a is unsocketed because it does not include a facet.
A socketed body opening 142b extends through socket fitting body 141b, and a socketed body channel 143b extends through socket fitting body 141b and between socketed body opening 142b and socket stop piece 144. Channel body 143b is socketed because it includes a facet, which are denoted as facets 147a, 147b, 147c, 147d. 147e and 147f in FIG. 8d. It should be noted that six facets are shown in FIG. 8d for illustrative purposes. In general, channel body 143b is socketed because it includes one or more facets. Socketed body opening 142b is sized and shaped to receive a fastener, such as fastener 107 of FIG. 1, or fasteners 108 and 109 of FIGS. 2a and 2b, respectively. It should be noted that the number of facets of channel body 143b is chosen to match the number of facets of head 108a or head 109a. In this way, heads 108a and 109a are capable of extending through socketed body opening 142b and socketed body channel 143b. Channel body 143b is faceted so that the fastener received by socketed body opening 142b rotates in response to the rotation of socket piece 140.
Socket piece 140 includes opposed fastener openings 145a and 145b, which extend through socket piece body 141. Fastener openings 145a and 145b are positioned opposed to each other, as shown in FIG. 8c, so that an object, such as a fastener, can be extended through them. Further, fastener openings 145a and 145b are positioned so that conduit fastener openings 118a and 118b are aligned with fastener openings 145a and 145b, respectively, when distal conduit end 110b of conduit 110 is extended through unsocketed body opening 142a. In this way, a fastener (not shown) can be extended through unsocketed body opening 142a and conduit fastener openings 118a and 118b so that socket piece 140 and distal conduit end 110b of conduit 110 are coupled together, as shown in FIG. 1.
