Patent number: 9327951Abstract: A hydraulic drive system readily adapted for either manual actuation or motor-driven actuation due to the unique design of the hydraulic drive and its coupling to either a hand crank or to a motorized drive to provide hydraulic pressure to lift cylinders that can be attached to table legs for vertical adjustment. The hydraulic drive includes a screw jack having an end extending from one end of a housing and splined or otherwise keyed. A manual crank arm or motorized drive assembly includes a coupling which mates with the end of the screw jack to provide a drive force for the hydraulic cylinder drive. The motorized drive assembly includes a pair of toothed hubs and an intermediate flexible sleeve allowing alignment of the motorized drive to the drive assembly as well as providing sound dampening, a cushioned coupling, and facilitates overcurrent detection.Type: GrantFiled: April 30, 2012Date of Patent: May 3, 2016Assignee: Suspa GmbHInventor: James E.

Patent number: 7806384Abstract: A lift includes a housing for rotatably receiving a hydraulic cylinder with a piston rod coupled to a generally cylindrical support tube. A low profile connecting head for supplying hydraulic fluid to the cylinder is rotatably mounted to the housing but captively held to the housing in the axial (longitudinal) direction. This allows the connecting head to be rotated during installation of the lift to a table leg for easy coupling to the pressurized source of hydraulic fluid.Type: GrantFiled: September 11, 2007Date of Patent: October 5, 2010Assignee: Suspa IncorporatedInventor: James E.

Patent number: 6711985Abstract: A glide adapter for a lift includes an inner seal extending between the piston rod and glide adapter to prevent leakage of hydraulic fluid which may escape the hydraulic cylinder from seeping from the lift. The sealed glide adapter comprises a generally cylindrical member having an axially extended threaded section for receiving a threaded glide at one end and a cylindrical recess formed at an opposite end, including an undercut recess for snap-receiving a resilient polymeric cylindrical seal which includes an annular groove for receiving an O-ring extending between the outer surface of the seal and the inner cylindrical surface of the glide adapter. The seal includes a blind aperture for receiving one end of the piston rod of the hydraulic cylinder. This design also facilitates servicing of the unit by allowing removal and replacement of the hydraulic cylinder.Type: GrantFiled: November 13, 2002Date of Patent: March 30, 2004Assignee: Suspa IncorporatedInventor: James E.
