Definitions

  • a pole climbing apparatus for use in the installation and repair of telephone lines and the like comprising an upper work platform and a lower climbing platform.
  • U. S. 3,856/111 shows a hand-climber-accessory for tree-climbing platforms for hunters and a horizontal base plate having a tree engaging blade. Angularly disposed frame members extend from the base plate to support a second blade or strap to engage the opposite side of the tree.
  • the hand-climber accessory is positioned on the tree above the platform and includes parallel bars to engage the tree. Blades are attached to the bars to engage the tree.
  • a hunter standing on the base plate alternately adjusts the elevation of the hand-climber accessory with respect to the base plate and raises or lowers the base plate by lifting and lowering his feet to first disengage and reengage the platform with respect to the tree at a different elevation.
  • U. S. 3,460,649 disclosed a similar climbing platform having a base plate positioned against the pole or tree. The operator places his arms around the pole or tree and pulls his feet upwardly to climb the pole or tree by raising the plate with respect to the pole or tree.
  • U. S. 3,955,645 discloses another hand-held climbing device in combination with a standing platform for climbing a tree by lifting his body with his feet in foot straps on the platform. This pivots the platform away from the tree so that the platform may be slipped up into a new position. When the platform is then pressed against the tree, it will be held in place so that the hand-held climbing device may then be pivoted upward to release and shimmied up the tree.
  • U. S. 3,463,320 illustrates a device for climbing a tree by this approximate method.
  • the upper framework is shimmied up the tree against the force of a series of elastic vertical straps attached between the frame and a lower platform.
  • the framework is then pivoted against the tree to lock it in place and the weight of the person is supported on the upper framework with the feet being raised so that the elastic straps may pivot the lower platform away from the tree to release it and raise it up the tree.
  • the upper framework may then be raised by the person's hands to release it from the and shimmy it further up.
  • U. S. 3,419,108 discloses a portable tree stand engaging a tree and held in place by means of a series of spikes on the platform.
  • U. S. 2,392,538 and U. S. 2,842,300 show pivoting frameworks with a strap to engage a tree, the entire arrangement being moved upwardly by pivoting free from the tree and shimming up the tree under hand power.
  • the combination of hand-held pole grippers and foot operated pole grippers are shown in U, S. 213,715.

  • the upper base plate comprises a seat member while the first upper pole engaging element comprises a blade member including a plurality of pole engaging surfaces held in fixed spaced relation relative to the seat member to cooperatively form a leg opening therebetween.
  • the second upper pole engaging element comprises a pair of support members coupled in substantially U- or V-shaped configuration supporting a blade member including a plurality of pole engaging surfaces.
  • Each upper interconnecting member includes a plurality of apertures formed on the outer portion thereof to receive interlocking coupling elements attached to the pair of support members to permit lateral adjustment with poles or trees of various diameters.
  • upright support members fixedly support the second upper pole engaging element diagonally upward relative to the first upper pole engaging element.
  • the lower climbing platform is similarly constructed. Specifically the lower climbing platform comprises a lower base plate including a first lower pole engaging element formed on the inner portion thereof and a second lower pole engaging element coupled to the lower base plate by a lower interconnecting element comprising a pair of substantially parallel lower interconnecting members to position the lower climbing platform in a substantially horizontal position when in use.
  • the lower base plate comprises a foot support member having a pair of feet engaging elements.
  • the feet engaging elements each comprise foot holds and adjustable straps to cooperatively secure the operator's feet to the lower climbing plate when in use.
  • the first lower pole engaging element comprises a blade member including a plurality of pole engaging surfaces.
  • the second lower pole engaging element comprises a pair of support members coupled in substantially U- or V-shaped configuration supporting a blade member including a plurality of pole engaging surfaces.
  • Each lower interconnecting member includes a plurality of apertures formed on the outer portion thereof to receive interlocking coupling elements attached to the pair of support members to permit lateral adjustment thereof to facilitate use of the pole climbing apparatus with poles or trees of various diameters.
  • upright support members fixedly support the second lower pole engaging element diagonally upward relative to the first lower pole engaging element.
  • the upper working platform and lower climbing platform are secured to the pole or tree.
  • the operator then places his legs through the leg aperture and secures his feet to the lower climbing platform by feet engaging elements.
  • the operator then stands up while lifting the upper work platform to provide maximum vertical separation between the upper work platform and lower climbing platform.
  • While seated on the upper work platform the operator raises his legs lifting the lower climbing platform upwardly to reduce the vertical separation between the two platforms. This process is continued until the desired vertical height on the pole is reached.
  • the operator may sit on the upper work platform.
  • the operator may also stand on the lower climbing platform during use.
