text: embodiments are described more fully below with reference to the accompanying figures , which form a part hereof and show , by way of illustration , specific exemplary embodiments . these embodiments are disclosed in sufficient detail to enable those skilled in the art to practice the invention . however , embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein . the following detailed description is , therefore , not to be taken in a limiting sense in that the scope of the present invention is defined only by the appended claims . the motorized extension pole of this invention is referred to by the reference numeral 10 . extension pole 10 includes an elongated hollow outer pole member 12 having a first end and a second end . an elongated hollow inner pole member 18 , having a first end 20 and a second end 22 , is telescopically slidably received within pole member 12 . pole member 18 may have a hexagonal , octagonal or a cylindrical cross - section . if the pole member 18 has a hexagonal cross - section as seen in fig3 and 6 , a fitting 24 , having a hexagonal - shaped bore 25 , is mounted on the end 16 of pole member 12 to prevent rotation of pole member 18 with respect to pole member 12 . if the pole member 18 has an octagonal cross - section , as seen in fig7 , the fitting 24 will have an octagonal - shaped bore 25 ′ to prevent rotation of pole member 18 with respect to pole member 12 . in a conventional extension pole , some means is provided to retain the pole member 18 in its various longitudinal positions with respect to pole member 12 . if pole member 18 has a cylindrical cross - section , a conventional collet will be mounted on the second end of the pole member 12 to clamp pole member 18 in its various selective positions with respect to pole member 12 in conventional fashion . however , in the instant invention , there is no need to provide such a collet or other structure to clamp the pole member 12 to the pole member 18 . regardless of whether the pole member 18 has a hexagonal , octagonal or cylindrical cross - section , the second end of the pole member 18 will have a threaded stud 26 at the outer end thereof to which objects such as a paint roller 28 may be attached . a chain saw , hedge trimmer , window cleaner or gutter cleaner could also be attached to the threaded stud 26 . an elongated threaded screw or bolt member 28 is positioned in the interior of pole member 18 . screw member 28 will be described as having a first end 30 and a second end 32 . a fitting 34 is secured to the first end 30 of screw member 28 and a fitting 36 is secured to the second end 32 of screw member 28 . fitting 36 rotatably receives the end 32 of screw member 28 . fitting 36 is held in place with respect to pole member 18 by screw 38 as seen in fig4 . collar 40 is secured to pole member 18 at end 20 by screw 42 as seen in fig4 . internally threaded nut 44 is fixed to collar 40 by any convenient means such as adhesive , press - fit , etc . the numeral 46 refers to a conventional battery driven tool such as a screw driver 44 , the motor of which is selectively reversible and turned on and off by the thumb switch 48 . the motor of the tool 46 is also a variable speed motor . tool 46 includes a driven , rotatable socket 50 which is driven by the motor of the tool 46 in conventional fashion . tool 46 is attached to the lower end of pole member 12 by any convenient means such as a sleeve 52 , the ends of which are clamped onto the pole member 12 and the tool 46 by clamps 54 and 56 respectively . as seen in fig4 , when the tool 46 is secured to the lower end of pole member 12 , socket 50 receives fitting 34 so that rotation of socket 50 causes screw member 28 to be rotated . the rotation of screw member 28 in one direction by tool 46 causes pole member 18 to be moved outwardly with respect to pole member 12 to increase the length of the extension pole 10 . the rotation of screw member 28 in the opposite direction causes pole member 18 to be moved inwardly with respect to pole member 12 thereby decreasing the length of the extension pole 10 . the extension and retraction of pole member 18 with respect to pole member 12 is accomplished without rotation of pole member 18 since nut 44 is fixed to collar 40 which is fixed to pole member 18 which is fixed against rotation with respect to pole member 12 by fitting 24 . when the extension pole 10 is being used such as illustrated in fig1 , the length of the extension pole may be increased or decreased simply by the operator actuating the motor of the tool 46 to either retract pole member 18 with respect to pole member 12 or to extend pole member 18 with respect to pole member 12 . the extension and retraction of the pole member 18 with respect to pole member 12 is accomplished by the operator without the need for lowering the pole and then adjusting the length of the same such as is necessary in prior art extension pole devices . fig5 illustrates the means for preventing rotation of the inner pole member 18 ′, which is generally cylindrical , with respect to the generally cylindrical outer pole member 12 ′. in the embodiment of fig5 , the collar 40 ′ has a lug 58 projecting therefrom which is received by an elongated recess 60 provided on pole member 12 ′. during the extension or retraction of the inner pole member 18 ′, the positioning of the lug 58 in the recess 60 prevents rotation of pole member 18 ′ with respect to pole member 12 ′. thus it can be seen that the invention accomplishes at least all of its stated objectives . although the invention has been described in language that is specific to certain structures and methodological steps , it is to be understood that the invention defined in the appended claims is not necessarily limited to the specific structures and / or steps described . rather , the specific aspects and steps are described as forms of implementing the claimed invention . since many embodiments of the invention can be practiced without departing from the spirit and scope of the invention , the invention resides in the claims hereinafter appended .
