| titleOfInvention | Improved pneumatic counterbalance |
| abstract | ABSTRACT OF THE DISCLOSURE A pneumatic spring counterbalance extensible link including a closed end cylinder with an end connector a piston and rod assembly within the cylinder and maintained therein by the crimped over end portion of the cylinder retaining a rod bushing and rod to cylinder seal. The cylinder is pressurized prior to assembly of the complete piston and rod assembly into the cylinder. The piston assembly includes orifice by-pass means either in the piston periphery or in a piston ring, and the piston may include a fail-safe provision in the event the orifice is clogged. A crimping die assembly is used in assembling and completing final assembly of the counterbalance components while simultaneously maintaining the link in a pressurized environment, utilizing a sealed arrangement between the crimping dies to maintain pressurization of the interior of the dies and the counterbalance components prior to assembly of the components. A dual force embodiment of the counter-balance unit is disclosed and utilizes a floating sealed piston below the main piston and rod assembly. entrapping pre-charged gas in the space between the floating piston and the closed end of the cylinder. |
