ABSTRACT

In one variation, a pulley arrangement includes a base pulley portion
rotatable within a driving plane, an adjustable pulley portion coupled to the
base pulley portion wherein the adjustable pulley portion is rotatable
relative to the base pulley portion within the driving plane, and a driving
member including an end coupled to the adjustable pulley portion wherein at
least a portion of the driving member is wrapped at least partially around the
adjustable pulley portion. In another variation, a pulley arrangement includes
a base pulley portion rotatable around an axis, an adjustable pulley portion
coupled to the base pulley portion and movable in a first direction parallel
to the axis, and a sliding block engaged with the adjustable pulley portion,
wherein the sliding block moves in a second direction different from the first
direction, in response to compression of the adjustable pulley portion against
the base pulley portion.
