Pole climber
Kind Code:

The pole climber is designed to allow an individual to move vertically up and down a tree or pole with little physical exertion, depending instead on the power and design of the device. An electrically powered motor and pair of metal drums set on opposite ends of a bar-like component, the drums fitted with metal teeth, or spikes would turn, biting into the surface being climbed. The individual stands or sits on the platform while operating the motor, that turns the drums, moving the device and person vertically up & down as desired.

1. The device consists of 2 elements a is the climbing assembly b is the power assembly you place a to tree using gravity you hook motor to b power assembly causing device to move up and down tree



Operate, which contributes to their lack of safety. Most of the prior art grips tree on two sides, basically front & rear: which renders the stand unstable if the user places his weight on one side of the platform.

All of the prior art share the problems of excess weight awkwardness and noisiness. Each of these problems renders the design inefficient for its intended use.


The climber is set at the base of tree or pole to be climbed, the two drums seperated, then placed on opposite side of tree. Then adjusted to tree size, bolted together, the the motor is turned on in the up position. The drum turns giping the tree or pole and starts up. The individual then climbs on the platform and up they go.

A seat is provided with few parts and folds out of the way when not in use.

Further objects and advantages of this invention will become apparent from a consideration of the drawings and ensuing description.

A 1″ drive shaft 18 which is attached to side element 42 in a bearing 19 other end of shaft 18 is attached to side element 44 in a bearing 24, with the 1″ shaft 18 sticking past side element 44 to engage with worm drive gear box 27 which is mounted to the side of side element 44 with mount bracket 26.

A cordless drill 29 is attached to ⅜ shaft 27 which drives worm drive gear box 26 turing 1″ shaft 18 which rotates spiked climbing drum 20 while engaging back side of tree moving climber up or down.

Upper frame member 23 also includes a inner tube 47 that slides in side element 42 where side element 42 is cut in half, fixed on one end by 1″ bearing bolt 19 other end of inner tube 47 is drilled with side element 42 with matching holes 17 with inner tube 48 that slides in side element 42 where side element 44 is cut in half, fixed on one end by 1″ bearing bolt 49 other end of inner tube 48 is drilled with side element 44 with matching holes 49.

Making the assembling adjustable for different size trees.

Frame 23 also includes a foot platform 33 which accommodates the feet of the user.

Platform 33 is attached to transverse elements 11, 41, and side elements 42 &44.

Platform 33 is made of a material of sufficient strength to support the user, such as expanded metal.

A climbing stand comprised of a single climbing assembly 10 and a foot platform 33, in a climbing configuration is illustrated in FIG. 2.

In the preferred embodiment, the frames 11, 12, 23, and 35 are made of a rigid material of sufficient strength to support the user; such as steel or aluminum tubing.

As illustrated in FIGS. 1-3, frame 23 comprises a side element 42 and a side element 44 of predeterming dimensions, each having a section with a plurality of engagement holes 17 and substantially horizontal section 33 forming its distal end.

Frame 23 includes a transverse element 11 &41 and upper frame member of predetermined dimensions, with one end attached to side element 42 and a second end attached to side element 44, these attachments being on the distal side of the forming the inclined sections of side elements 42 and 44, brace 13 together with transverse element 41 and side element 42; as well as brace 45 together with transverse element 41 and side element 44, form triangular relationships in both the horizontal and vertical planes; thereby restraining both lateral and vertical displacement of the inclined sections. Spiked trailing drum 46 and transverse element 41 form an abutment, for tree engagement, on the user's side of the tree.

Frame 23 also includes a tree-gripping spiked climbing drum 20. Assembly 20 includes a 1″ drive.
