Motorized extension pole

摘要

A motorized extension pole including a first hollow pole member having a second pole member telescopically mounted in said first pole member. The second pole member is selectively moved between extended and retracted positions with respect to said first pole member by a battery powered drive motor. The drive motor is mounted within a handle attached to the inner end of the first pole member. A coupling mechanism interconnects the handle to the first pole member which permits the first pole member to be selectively rotated without rotating the handle so that the control switch on the handle is always located in a convenient position. The pole also includes limit switches for controlling the retraction and extension of the second pole member.

主权项

1. A motorized extension pole, comprising:
a first elongated, hollow pole member, having first and second ends; a handle, having inner and outer ends, secured to said first end of said first pole member; a second elongated, hollow pole member, having first and second ends, telescopically mounted in said first pole member and which extends thereinto from said second end of said first pole member; said second end of said second pole member protruding from said second end of said first pole member; said second pole member being telescopically movable between retracted and extended positions with respect to said first pole member; a selectively reversible battery powered drive motor positioned in said handle member; a switch mounted on said handle member for controlling said drive motor; said drive motor having a power shaft extending therefrom towards said outer end of said handle member; an extension and retraction mechanism interconnecting said first and second pole members for selectively extending and retracting said second pole member with respect to said first pole member; a coupling mechanism operatively interconnecting said handle member and said first end of said first pole member which is configured to permit said first pole member to be selectively rotated about the longitudinal axis of said first pole member without rotating said handle member.
