Latest Patents
David E Grass holds a patent for a "Metal/elastomeric bumper for air springs." This invention features a pair of spaced end members that mount the spring at designated locations on a structure. A flexible sleeve made of elastomeric material is sealingly engaged with the end members, forming a pressurized fluid chamber between them. The design includes a post mounted on one of the end members that extends into the fluid chamber. A shock-absorbing two-piece bumper consists of a rigid metal base shaped like an inverted cup with a cylindrical sidewall. This base is secured to one of the end members, allowing the post to extend into the open end of the base member. An elastomeric member is snap-fitted into a hole in the end closure wall of the base member, engaging the opposite end member when the air spring fails or experiences significant deflection. An alternate embodiment features flexible fingers formed from the cylindrical sidewall of the base, which are snap-fitted to the post for mounting.
