Patent ID: 7717381

Claim:
A pneumatic corner climber comprising: an extendable bellow comprising a first end and a second end; an upper clamp member attached to said first end comprising a first hollow compartment; a lower clamp member attached to said second end comprising a second hollow compartment; and a controller for independently increasing and decreasing pneumatic pressure of said first compartment, said second compartment, and said extendable bellow; wherein said upper and said lower clamp members comprise a high friction material having a coefficient of friction equal to or greater than one; wherein increasing said pneumatic pressure of said first and said second compartments causes said upper and said lower clamp members to securely engage a first surface and a second surface; wherein decreasing said pneumatic pressure of said first and said second compartments causes said upper and said lower clamp members to disengage said first surface and said second surface; wherein increasing said pneumatic pressure of said extendable bellow causes said upper and said lower clamp members to move away from each other; wherein decreasing said pneumatic pressure of said extendable bellow causes said upper and said lower clamp members to move towards each other; and wherein said first and said second surfaces are at an angle of at least about 90 degrees with respect to each other.
