Gliders from University of Miami. A glider or platform rocker is a type of rocking chair that moves as a swing seat, where the entire frame consists of a seat attached to the base by means of a double-rocker four-bar linkage. The non-parallel suspension arms of the linkage cause the chair to simulate a rocking-chair motion as it swings back and ...
"A glider is an updated version that’s designed to slide forward and backward rather than rock in an arc". See Four bar linkage, "parallelogram" linkage. Granted, not all gliders purely glide back & forth, some do "rock" and change the tilt angle. Likewise, some gliders have the four-arm mechanism mostly enclosed and are safer than a rocker.
A rocking chair or rocker is a type of chair with two curved bands (also known as rockers) attached to the bottom of the legs, connecting the legs on each side to each other. The rockers contact the floor at only two points, giving the occupant the ability to rock back and forth by shifting their weight or pushing lightly with their feet.

The linkage consists of the frame, a crank, two grounded rockers, and two couplers all connected by pivot joints. It was developed by Joe Klann in 1994 as an expansion of Burmester curves which are used to develop four-bar double-rocker linkages such as harbor crane booms. [2] It is categorized as a modified Stephenson type III kinematic chain.
The FPG-9 Foam Plate Glider is a simple, hand-launched glider made from a 9 inch (23 cm) foam dinner plate, featuring a moveable rudder and elevons, allowing for an inexpensive way to teach basic flight mechanics. The model was created by Jack Reynolds, a volunteer at the Academy of Model Aeronautics' (AMA) National Model Aviation Museum. [1]
