Abstract
A system for adjusting a path of a wire includes a precast pulley assembly having at least one precast pulley having at least first and second positions. The at least one precast pulley may be adjustable from the first position to the second position without a user touching the at least one precast pulley. A path of a wire is adjusted when disposed around the at least one precast pulley when it is in the second position instead of in the first position. In one embodiment, the precast pulley assembly includes first and second precast pulleys disposed in an adjacent relationship with respect to one another, wherein a wire can selectively pass over one or both of the first and second precast pulleys.
Claims14
A system for adjusting a path of a wire, the system comprising:
- a precast pulley assembly comprising at least one precast pulley, wherein the at least one precast pulley comprises first and second precast pulleys disposed in an adjacent relationship with respect to one another,
- wherein the wire can selectively pass over one or both of the first and second precast pulleys,
- wherein in a first position the wire engages the second precast pulley and bypasses the first precast pulley, and wherein in a second position the wire engages both the first and second precast pulleys,
- wherein the at least one precast pulley is adjustable from the first position to the second position without a user touching the at least one precast pulley, and
- wherein in a third position the wire engages the first precast pulley and bypasses the second precast pulley.
A system for adjusting a path of a wire, the system comprising:
- a precast pulley assembly comprising at least one precast pulley, wherein the at least one precast pulley comprises first and second precast pulleys disposed in an adjacent relationship with respect to one another;
- and
- a support assembly configured to hold the first and second precast pulleys in a predetermined angular orientation and to enable circumferential rotation of the first and second precast pulleys,
- wherein the wire can selectively pass over one or both of the first and second precast pulleys,
- wherein the first precast pulley has a different shape than the second precast pulley, and
- wherein in a first position the wire engages the second precast pulley and bypasses the first precast pulley, and wherein in a second position the wire engages both the first and second precast pulleys.
A system for adjusting a path of a wire, the system comprising:
- a precast pulley assembly comprising at least one precast pulley, wherein the at least one precast pulley comprises first and second precast pulleys disposed in an adjacent relationship with respect to one another,
- wherein the wire can selectively pass over one or both of the first and second precast pulleys,
- wherein in a first position the wire engages the second precast pulley and bypasses the first precast pulley, and wherein in a second position the wire engages both the first and second precast pulleys, and
- wherein the at least one precast pulley is adjustable from the first position to the second position without a user touching the at least one precast pulley;
- a support assembly configured to hold the first and second precast pulleys in a predetermined angular orientation and to enable circumferential rotation of the first and second precast pulleys,
- wherein the support assembly comprises a driven member coupled to a frame, where the frame extends in a lateral direction with respect to the driven member,
- wherein the frame comprises a first region to which the first precast pulley is coupled, a second region to which the second precast pulley is coupled, and a central region disposed between the first and second regions to which the driven member is coupled, and
- wherein the first region of the frame comprises a bore formed therein, and a shaft of the first precast pulley is disposed through the bore and adapted for selective longitudinal advancement relative to the bore of the frame.
