  • Patent number: 4951942
    Abstract: A multiple purpose exercise device has a base unit (19) and a telescopic lever arm (15, 16) which supports and holds various widths and lengths of elastic biasing cord (18). Contained within the base unit is a lock fastening device (20) which secures the elastic biasing cord in place to prevent movement when stretching the cord during exercise. The base unit and telescopic lever arm can be attached to a collapsible framework (21, 22, 23, 24) for a wider variety of anaerobic type exercises. The framework consists of four rectangular formed sections (21A, 22A) connected by two rotatable locking hinges (22E, 21H, 25) and supported by three collapsible rectangular shaped stabilizer members (23A, 23E, 23B, 24A, 24B). In conjunction with the framework, the base unit, the telescopic lever arm and the biasing cord, a pair of rectangular length rails (26) each supporting a free rolling gliding unit (27) can be employed for aerobic type exercises.
