Pilates Reformer With an Articulated Movable Platform
Pilates reformers, and exercise apparatus, are widely used by individuals of varying levels of fitness. The moveable carriage of the reformer onto which the person is to lie supine during exercise is difficult to mount for some individuals, such as the elderly or pregnant women. A replacement for the planar one-piece carriage is disclosed that is a two-piece platform having a seat portion and a back portion that pivots with respect to the seat portion. The individual can mount the exercise apparatus on the seat portion with the inclined back portion for support. The back portion can then be lowered to a completely horizontal position or slightly inclined, depending on the needs of the individual. An articulated platform has an extendible gas spring mounted between the back portion and a support structure. The gas spring assists the individual, or a trainer, to move the back portion up.

The present disclosure relates to exercise equipment, in particular a Pilates reformer.
BACKGROUNDJoseph Pilates, born in Germany in 1883 suffered from various aliments including asthma, rickets, and rheumatic fever and was a sickly child. Due to his parents' influence: his father being a prize-winning gymnast who ran a gym and his mother who followed a naturopathic philosophy, believing in stimulating the body to heat itself without artificial means but with fresh air and exercise; and due to his internment in England in a camp on the Isle of Man, he developed his system of exercise in particular for working with injured soldiers too weak to get out of bed. He initially relied on available components, such as bed frames and springs, to construct exercise equipment to maintain both physical and well-being for himself and the other prisoners. Joseph Pilates patented an exercise device in 1927, U.S. Pat. No. 1,621,477. A figure from Pilates' patent is shown as the
There are many followers of Pilates' movement. An example of a modern Pilates reformer is illustrated in
Some individuals have trouble getting situated onto the carriage, particularly in a recumbent position even with the assistance of an instructor. If the instructor is smaller and the participant is larger, it could lead to an injury for the instructor and/or the participant. Some participants, such as elderly people or pregnant women may not be able to, or may be restricted from, exercising in a supine position even if they could access the recumbent position, thus preventing from such participants from using the Pilates reformer.
Many hospital beds are equipped with electric motors with a controller for the patient to control the inclination angle of the bed. The requirement for an outlet and power cords snaking on the floor present disadvantages for an exercise area. A prior art hospital bed in which the movement of the bed from a recumbent position is accomplished without electrical power assistance is shown in U.S. Pat. No. 7,472,442. A gas spring is used to provide assistance in lifting the part of the bed supporting the back. When such a position for the back is accessed, the seat of the bed and the portions of the bed on which the patient's legs sit all move in response to actuating the gas spring to raise the back, some sliding with respect to the frame and the leg portions, in particular, raising upward with respect to the seat of the bed
