Abstract: A pedal carrier (14) is movably supported by the support (12) for adjustment between various operational positions. The support (12) includes a rod (16) and the pedal carrier (14) is slidably supported on the rod (16). The carrier (12) includes an arm (30) extending from the support (12) and a fitting defining a first end (26) of a conduit (24) is retained in an aperture in the arm (30). A pedal lever (20) includes an actuator portion (38) extending upwardly from a pivotal pin (22) and a first end (34) of a core element (32) is attached to the actuator portion (38). The pedal lever (20) also includes a pedal portion (40) extending downwardly from the pivotal pin (22) so that the pin (22) acts as a fulcrum in response to a pedal force applied to the pedal portion (40) to place the core element (32) in tension.
