Estimating the term…
A straight back side chair has a seat cushion and a back member, and includes a low resistance loading device that is operated through a system of cords and pulleys from handgrips. The pulleys are supported on arms that are mounted to the back of the chair and which can be selectively positioned for different types of exercise. The arms can be positioned laterally out from the sides of the chair for doing butterfly type exercise; pushed downwardly at an angle for curls; or positioned overhead above the back of the chair for permitting a person seated in the chair to do pull downs. When the chair is not in use as an exerciser, the arms are folded out of the way so it functions as a side chair and does not visually intrude on the usable space in a room or tend to give the room the look of a gymnasium. The force resistance device is very compact so that it takes litter space beneath the seat, permitting a cushioned or padded seat to be used. A panel having a display of counters, force indicators and the like can also be mounted on the chair seat and made to be retractable when not in use.

A chair comprising a seat, frame means for supporting said seat above a surface including an upright back frame, said back frame being positioned to support the back of a person seated on said seat, a loading device operable to apply a drag on a movable element forming part of said loading device, said loading device being mounted on said frame means beneath said seat and above said surface on which the chair is supported, flexible line means connected to said movable element of said loading device, and an operable exercise frame element including at least one retractable tubular arm portion positioned to the rear of said back frame of the chair and movable to a position wherein said arm portion extends outwardly from the chair, said line means being mounted to be guided on a first pulley rotatably mounted at an inner end of pivoting of said arm portion adjacent said back frame and to pass within an interior space defined by said retractable tubular arm portion from said inner end to an outer end, and a second pulley at said outer end of said retractable tubular arm portion comprising a castering pulley that casters about a castering axis generally parallel tot he longitudinal axis of said retractable tubular arm portion and parallel tot he axis of said line extending within said retractable tubular arm portion, and having a pulley wheel which rotates on an axis perpendicular to the castering axis, and said second pulley being of size to guide said flexible line means from said outer end of said retractable tubular arm portion to a position clearing an outer surface of said retractable tubular arm portion when said flexible line means is doubled back on the exterior of said retractable tubular arm portion, and a third pulley mounted on the exterior of said retractable tubular arm portion adjacent said inner end thereof and positioned on said retractable tubular arm portion laterally outwardly from said back frame of the chair when said retractable tubular arm portion is extending laterally of said back frame, whereby said flexible line means is guidable out of said outer end of said retractable tubular arm portion, around said second pulley, back toward said inner end of said retractable tubular arm portion, and then guided by said third pulley forwardly to positions permitting a person seated on said seat to pull forwardly on said flexible line means to cause movement of said movable element of said loading device.
A convertible exerciser comprising frame means to support a seat above a surface, an upright back frame connected to said seat, a loading device carried by said frame means beneath the planform of said seat, and operable to apply a resistance load when loaded, line means connected to said loading device whereby upon outward movement of said line means said loading device provides a resistance force to said line means, an operable exercise support including at least one arm portion mounted to a portion of said frame means and movable between a storage position wherein said arm portion is concealed behind said upright back frame, and an exercise position wherein said arm portion extends laterally from said frame means, and guide members mounted on said frame and arm portion, said line means being mounted relative to said guide members so that upon movement of said line means in a direction away from said loading device said line means is moved and said loading device is operated.
A convertible exerciser comprising frame means to support a seat above a surface, an upright back frame connected to said seat, a loading device carried by said frame means and operable to apply a resistance load when loaded, line means connected to said loadign device whereby upon outward movement of said line means said loading device provides a resistance force to said line means, an operable exercise support including at least one arm portion having an inner end and positioned to the rear of said back frame, said arm portion being retractable from a generally horizontal position extending laterally from said frame means to a position at the rear of said back frame and within a perimeter area defined by said back frame, and guide members mounted on said frame and arm portion, with said line means being mounted relative to said guide members so that upon movement of said line means in a direction away from said loading device said line means is moved and said loading device is operated.
An exercise chair comprising a seat, a frame to support said seat above a surface, said frame including an upright back frame positioned to support the back of a person seated on said seat, a resistance force generator device positioned beneath the planform of said seat, said resistance force generator device comprising a rotatable disk and brake, a pair of flexible lines connected to rotatable pulleys to cause rotation of said disk when one or the other flexible line is extended, said brake being actuated upon rotation of said disk to provide frictional resistance to extension of said flexible line means, an operable exercise frame carried by the chair including a pair of retractable arms movably mounted to a portion of said frame of the chair and each arm being movable between a storage position wherein each arm is concealed behind said upright back frame, and an exercise position wherein each arm extends outwardly from the chair, means mounted on each arm for guiding a respective one of said flexible lines to outer ends of said respective arm so that said lines are spaced from each other and positioned to be moved by a person seated on said seat, and whereby when either of said lines is moved said resistance force generating device is moved to cause a brake load on said respective line.
