Abstract
A telescoping lever arm comprises a tube and a rod. The tube has an opening at one end thereof and has an inner circumferential dimension along the inside thereof. The opening is smaller than the inner circumferential dimension of the tube. The rod has an outer circumferential dimension that is smaller than that of the tube's opening. The rod resides partially in the tube and extends therefrom via the tube's opening. At least one annular flange is coupled to the rod at a portion thereof residing in the tube. Each such annular flange is defined by a circumferential dimension that is larger than that of the tube's opening and smaller than the inner circumferential dimension of the tube.
Claims12
A telescoping lever arm, comprising:
- a tube having an opening at one end thereof and having an inner circumferential dimension along the inside thereof, wherein said opening is smaller than said inner circumferential dimension;
- a rod having an outer circumferential dimension that is smaller than that of said opening, said rod residing partially in said tube and extending therefrom via said opening;
- at least one annular flange coupled to said rod at a portion thereof residing in said tube, each said annular flange defined by a circumferential dimension that is larger than that of said opening and smaller than said inner circumferential dimension of said tube;
- and
- at least one annular rib formed on an inner surface of said tube, each said annular rib defining a passage large enough to pass said rod and each said annular flange.
A telescoping lever arm, comprising:
- a cylindrical tube having an inner diameter and having a circular opening at one end thereof, wherein said circular opening defines a diameter that is smaller than said inner diameter;
- a cylindrical rod having an outer diameter that is smaller than that of said circular opening, said cylindrical rod residing partially in said cylindrical tube and extending therefrom via said circular opening;
- at least one circular disk coupled to said cylindrical rod at a portion thereof residing in said cylindrical tube, each said circular disk defined by a diameter that is larger than that of said circular opening and smaller than said inner diameter of said cylindrical tube;
- and
- at least one annular rib formed on an inner surface of said cylindrical tube, each said annular rib defining a passage large enough to pass said cylindrical rod and each said circular disk.
