This invention relates generally to the field of Pilates exercise equipment and more particularly to a machine which combines three Pilates exercise systems-reformer, pole, and chair in one footprint, and which may be folded into an upright position for storage and rolled for relocation.
The prior art includes numerous designs of Pilates type exercise equipment, beginning with the original U.S. Pat. No. 1,621,477 issued to Pilates for a wheeled platform carriage connected to a resistance device.
A reformer exercise apparatus typically includes a wheeled platform carriage which rides on parallel rails or tracks on a rectangular wooden or metal frame. Most devices employ a series of parallel springs or elastic members which connect the carriage to the foot end of the frame. The springs are manually interchangeable in order to provide a variable resistance.
The carriage typically includes stationary shoulder pads and a head rest. It is desirable to be able to convert the carriage with its raised shoulder pads and a head rest into a flat surface.
A foot bar is located at the foot end of the device so that the user can press one or both feet against the foot bar and push the carriage against the spring resistance. Adjusting the position of the carriage in relation to the foot bar is important to accommodate different body types, and is typically accomplished by manually moving a spring bar into different gear settings at the foot end of the reformer or by adjusting the foot bar position. It is desirable to provide a simple mechanism which allows for gear adjustment without requiring the user to interrupt the flow of exercise to make the necessary adjustment.
Pulleys mounted on pulley risers on support posts are often located at the head end of the reformer frame. The pulleys, themselves, are often adjustable in height during exercises where the user pulls the carriage by means of a rope or strap threaded through the pulley. The prior art pulley systems include swivel pulleys capable of accommodating ropes but not straps. Although a significant contingent of classical trained Pilates practitioners prefer the usage of flat straps, rather than ropes, the equipment typically provides only stationary, non-swivel casters or rollers when using flat straps. It is desirable to provide a fully articulating swivel pulley for straps as well as for ropes, thereby enabling the user to pull the carriage through its entire path without the binding and dragging of straps which typically occurs between the pulley and its bracket in the stationary design. It is also desirable to provide a swivel pulley which can be accommodated by a pulley riser system, and thereby allow the user to adjust the height position, as is currently available with rope systems.
Reformers are usually over 7 feet in length, and commercial models exist either as stationary units, or stackable units. The stationary units are difficult, impractical or time-consuming to move. Wheels have been added to the legs of such stationary units, but are of limited value, as they are bulky and ungainly to move, while the large amount of space required for the footprint of the unit remains the same. Stackable units typically require at least two persons to break down and stack in another location, or on a rolling cart, which then is wheeled to another location. It is, therefore, desirable to provide a device that can be folded into a minimal, space-saving footprint, which can be transported, if desired, by one individual.
It is desirable from the standpoint of economy of cost and space to provide a integrated Pilates machine which combines three Pilates machines—reformer, pole system and chair in one footprint, thus enabling the user to perform in this one machine most of the exercises in the full Pilates repertoire. In the current invention, the user can with no or very little compromise, and with ease of transition, perform exercises in the reformer mode, the pole system mode, and in a mat flat padded platform mode; and can perform a substantial number of chair exercises.
The prior art includes referenced to hinged or foldable frames. U.S. Pat. No. 3,770,267 issued to McCarthy describes an exercise machine without legs, which has a foldable frame. U.S. Pat. No. 4,706,953 issued to Graham describes an exercise machine which is collapsible by folding and by telescopic joints to make it more compact for transport and storage. U.S. Pat. No. 6,186,929 B1 issued to Endelman et al. describes a reformer apparatus with a two-part rail with a tongue connector. That patent includes a brief reference to an alternate embodiment where the tongues may include a hinged portion which permits the rail sections to be pulled apart and folded for transport.
The prior art includes references to wheels on the platform. U.S. Pat. No. 2,733,922 issued to Diego describes an exercise platform with four retractable wheels. The '929 patent describes a foldable reformer with no legs and two fixed wheels at the foot of the device.
Several prior art patents describe headrests on the carriage including the '922 patent, and U.S. Pat. No. 4,884,802 issued to Graham. U.S. Pat. No. 5,338,278 issued to Endelman describes a 4-position headrest. U.S. Pat. No. 5,681,249 issued to Endelman describes a removable headrest.
The prior art includes various footbar support designs. U.S. Pat. No. 1,738,987 issued to Dattilo describes a footbar with a pivot. The '922 patent and U.S. Pat. No. 5,066,005 issued to Luecke describe slots to adjust the footbar. The '278 patent describes a 2-way adjustment with a kick plate. U.S. Pat. No. 5,364,327 issued to Graham describes a kick plate which is adjustable along the track. U.S. Pat. No. 5,607,381 issued to Endelman describes a 2 position reversible bar on a metal frame. U.S. Pat. No. 5,653,670 issued to Endelman describes an adjustable bar and plate. The '249 patent describes a footbar which pivots for storage.
The prior art includes various designs of spring bar adjustment mechanism including the '249 patent which describes a rod and bracket, the '267 patent which describes a spring adjustment; the '987 patent; and U.S. Pat. No. 5,792,033 issued to Merrithew. U.S. Pat. No. 6,120,425 issued to Endelman describes a combination of anchor bar and carriage stop.
The prior art includes various designs of risers and pulleys including the '005 patent, the '278 patent, and the '922 patent which describes handbars. U.S. Pat. No. 3,586,322 issued to Kverneland describes an auxiliary frame. The '929 patent describes removable, non-adjustable risers.
The '249 patent describes panels on either side of carriage so that the carriage may be converted to a flat bench.
The present invention provides an attractive, durable, versatile, space-saving, and cost-saving commercial Pilates machine, which may be easily folded in to a minimal footprint and transported and stored out of the way.
The current invention features an improved Pilates machine. One embodiment of the invention includes an integrated piece of equipment which combines three Pilates machines—reformer, pole system and chair in one footprint, thus enabling the user to perform in this one machine up to 90% of the exercises of Pilates repertoire. The user can, with virtually no compromise, and with ease of transition, perform exercises in the reformer mode, the pole system mode, and a mat flat padded platform mode; and can perform a substantial number of chair exercises. One embodiment of the invention includes integrated components that, when set up, form a chair comprised of a chair pedal hinged to the wheeled base, multiple position spring attachments, and specially designed long/short box that doubles as a chair seat.
One embodiment of the invention includes the hinging of a professional-grade, heavy duty frame, so that the machine may be folded into an upright position; and a wheeled base, so that the folded upright machine may be wheeled to various locations for storage.
One embodiment of the invention includes a head rest and shoulder pad component which may be reversed by being flipped into a downward position, enabling the placement of a conversion mat on the frame to mate with the carriage pad in order to convert the reformer into flat platform mat.
One embodiment of the invention includes a gear changing mechanism located on the underside of the carriage, enabling the user to easily change the gear positions of the reformer with a simple single motion, without requiring the user to interrupt the flow of exercise by getting off the reformer to make the necessary adjustment.
One embodiment of the invention includes a fully articulating swivel pulley for both ropes and flat straps, thereby enabling the user to pull the carriage through its entire path without the binding and dragging which typically occurs with flat straps, between the pulley and its bracket in the stationary design.
One embodiment of the invention includes a mechanism which may be easily rotated in three positions to serve as an adjustable mechanism to which either the rope or strap pulleys are attached for use when in the reformer mode, as a support mechanism for the attachment of the chair springs when in the chair mode, and for out of the way storage when utilized in the pole system mode with the conversion mat in place.
The Invention may be more easily understood, and its benefits would become more apparent, with the viewing of the following figures:

In another set of exercises, the user typically pulls the platform by means of a rope, cable or strap through pulleys 154 which are each mounted on a rotatable risers 140. The user pulls the straps through the pulleys lying supine or prone, standing, or sitting on the carriage, facing back, front, or sideways, depending on the exercise. The pulley height may be adjusted as discussed below.
In another set of exercises, a chair is formed by positioning a box partially over rail sections 201 and 202.
The reformer may be folded into an upright position by lifting up on the lift handle 250, which also acts as a stabilizing bar between rail sections 200 and 203. The lift handle is raised until the base 180 is pulled over the inclined face 102 of the head base 100. The folding of the rails is assisted by head rail hinges 260 which permit rail sections 201 and 203 to rotate with respect to the head base poles 120.
The headrest can adjust to lie flat or incline with respect to the carriage surface. The headrest and shoulder pads are constructed as an integrated assembly and is hinged to the carriage platform so that it may be rotated 180° to face downward so that a conversion mat can be inserted to convert the reformer into a flat bed. The hinged headrest and shoulder pad assembly is double locked, and can be released by pulling a disengagement cable or rod located below the headrest. After disengaging the lock, the assembly can be rotated 180 degrees downward, and a mat may be placed over the rails and the assembly area in order, so that the carriage mat and the mat provide a continuous flat surface for performing mat exercises. This assembly is an improvement over prior art where shoulder rests are typically pinned to the carriage, and must be removed to provide a flat surface.

The carriage resistance is provided by a plurality of interchangeable springs 402, usually three or more springs. Each spring has a spring handle 403 which has a spring retaining ball 404 which may be extended and slipped into a spring handles slot 405 (not shown) on a spring retention plate 408 (not shown) on the reformer frame near the footbar in order to set one end of the spring. The second end of each spring 407 is secured in its respective retention slot 406 on a spring gear bar 410 so that the springs are parallel to the reformer rails. A gear changer 401 (not shown) may be pulled out from the base of the carriage thereby disengaging a spring gear bar 410 so that the user may slide the carriage while remaining on the carriage.
In this embodiment, the carriage is positioned in one of 5 positions determined by the position of the spring gear bar into appropriate slots 416a–416e of spring gear bar adjustment plates 415 which are positioned on both sides of the carriage.
The slots of this embodiment include 416c, a one position; 416d, a two position; and 416e, a three position. These three positions 416c, 416d, and 416e are typical of Pilates exercise equipment. In addition to these positions, the current invention includes a novel zero position, 416a, which is used only in the storage and movement of the apparatus; and a minus one position, 416b, which is not found in prior art. In this embodiment, the 416b position places the carriage closer to the foot base, such that the distance from 416b to 416c is the same as the distance from 416c to 416d. This setting is typically used by persons five feet or less in height.
The distance from the carriage platform to the spring attachment box at the foot of the frame is controlled by the location of the spring gear bar on the spring gear bar adjustment plates. The spring bar typically has multiple, interchangeable tension springs attached to it. The user attaches the free end of the spring to the spring retention plate in the spring attachment box at the foot of the reformer. At least one of the four springs attached to the spring bar must be engaged when changing gears. The user changes gears while lying or sitting on the carriage by pulling on a stiff wire loop, ball, or hand grip gear changer which pulls a cable or rod is proximity to the spring bar. Pulling on the gear changer causes the cable or rod to disengage the spring bar from its slot and moves the spring bar into a neutral position that allows the user to move the carriage forward or back, thereby engaging the spring bar in another position on the ratchet plate when the gear changer is released.
The carriage position corresponding to the spring bar position is marked on the side of the frame. Taller users generally use a position where the carriage platform is further away from the spring attachment box; shorter users generally use a position where the carriage platform is closer to the spring attachment box. There is also a “parked” position 416a, in which the carriage platform is adjacent to the spring attachment box. This is the position the carriage platform should be in before folding the reformer.
