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.
Claims (12)
1 . A pulley arrangement, comprising:
a base pulley portion rotatable around an axis;
an adjustable pulley portion in-plane with the base pulley portion and movable in a first direction parallel to the axis; and
a first sliding block engaged with the adjustable pulley portion;
wherein the first sliding block is configured to move in a second direction different from the first direction, in response to the adjustable pulley portion moving in the first direction.
2 . The pulley arrangement of claim 1 , further comprising a driving member comprising a first end coupled to the first sliding block, wherein at least a portion of the driving member is wrapped at least partially around the first sliding block.
3 . The pulley arrangement of claim 2 , wherein at least a portion of the driving member is wrapped at least partially around the adjustable pulley portion.
4 . The pulley arrangement of claim 1 , wherein a first member of the adjustable pulley portion includes at least one sloped surface engaged with the first sliding block.
5 . The pulley arrangement of claim 4 , wherein the sloped surface is a linearly slanted surface.
6 . The pulley arrangement of claim 1 , wherein the first sliding block includes at least one sloped surface.
7 . The pulley arrangement of claim 1 , wherein moving in the first direction compresses the adjustable pulley portion against the base pulley portion and the first sliding block is configured to move in a linear path in the second direction normal or perpendicular to the first direction in response to the adjustable pulley portion compressing against the base pulley portion.
8 . The pulley arrangement of claim 1 , wherein the adjustable pulley portion comprises a first member and a second member disposed in a recess of the base pulley portion, and the arrangement further comprises a second sliding block engaged with the adjustable pulley portion.
