• (2)a slideable block configured to slide along the track:
• (3)a single first pulley coupled to the slideable block and rotatable about a first axis that moves together with the slidable block, the first pulley being the sole pulley that is rotatable about the first axis:
• (4)at least one spring spool mounted at the first frame end;
• (5)a spring having a coiled part wound around the at least one spring spool, and having a segment that extends away from the coiled part and is coupled to the slideable block;
• and
• (6)a single second pulley disposed at the second frame end and rotatable about a fixed second axis, the second pulley being the sole pully that is rotatable about the second axis:
• (7) wherein
• (A)an intermediate storage section of a cable is ordinarily disposed within the frame, a first end of the intermediate storage section extending through a first opening located in one of the first and second frame walls, and a second end of the intermediate storage section extending through a second opening located at the second frame end,
• (B) the intermediate storage section of the cable extends from the first end of the intermediate storage section of the cable to the first pulley, then around the at least part of the first pulley, then from the first pulley to the second pulley, then around the at least part of the second pulley, and then from the second pulley to the second end of the intermediate storage section of the cable,
• (C)in response to the second end of the intermediate storage section of the cable being pulled away from the frame, the first pulley and the slideable block are urged away from the first frame end toward the second frame end thereby permitting a portion of the intermediate storage section of the cable to be withdrawn from the frame, the first pulley being the sole pulley being urged away from the first frame end, and
• (D) the at least one spring spool comprises
• (i)first and second spring spools each mounted at the first frame end, wherein
• (ii)a first coiled part of the spring is wound around the first spring spool, a second coiled part of the spring is wound around the second spring spool, and an intermediate segment of the spring connects the first and second coiled parts and is coupled to the slideable block.

A cable retractor, comprising:

• (a) a frame having first and second frame ends, opposing first and second frame walls disposed between the first and second frame ends, and a track extending along one of the first and second frame walls;
• (b) a slideable block configured to slide along the track;
• (c) a single first pulley coupled to the slideable block and rotatable about a first axis that moves together with the slidable block, the first pulley being the sole pulley that is rotatable about the first axis;
• (d) at least one spring spool mounted at the first frame end;
• (e) a spring having a coiled part wound around the at least one spring spool, and having a segment that extends away from the coiled part and is coupled to the slideable block;
• and
• (f) a single second pulley disposed at the second frame end and rotatable about a fixed second axis, the second pulley being the sole pulley that is rotatable about the second axis;
• (g) wherein
• (1) an intermediate storage section of a cable is ordinarily disposed within the frame, a first end of the intermediate storage section extending through a first opening located in one of the first and second frame walls, and a second end of the intermediate storage section extending through a second opening located at the second frame end,
• (2) the intermediate storage section of the cable extends from the first end of the intermediate storage section of the cable to the first pulley, then around the at least part of the first pulley, then from the first pulley to the second pulley, then around the at least part of the second pulley, and then from the second pulley to the second end of the intermediate storage section of the cable,
• (3) a second end of the intermediate storage section extends through a second opening located at the second frame end,
• (4) in response to the second end of the intermediate storage section of the cable being pulled away from the frame, the first pulley and the slideable block are urged away from the first frame end toward the second frame end thereby permitting a portion of the intermediate storage section of the cable to be withdrawn from the frame, the first pulley being the sole pulley being urged away from the first frame end,
• (5) the at least one spring spool further comprises
• (A) first and second spring spools each mounted at the first frame end, wherein
• (B) a first coiled part of the spring is wound around the first spring spool, a second coiled part of the spring is wound around the second spring spool, and an intermediate segment of the spring connects the first and second coiled parts and is coupled to the slideable block,
• (6) the spring exerts a nearly constant retraction force on the slideable block such that, in response to the second end of the intermediate storage section of the cable being at least partly pulled away from the frame and then released, the spring pulls the slideable block and the first pulley back toward the first frame end and retracts the withdrawn portion of the intermediate storage section of the cable back toward the frame, the first pulley being the sole pulley pulled back toward the first frame end,
• (7) the cable retractor further comprises
• (A) a staple catch disposed at one of (i) the slideable block or (ii) the frame at the second frame end, and
• (B) a latch part disposed at another of (i) the slideable block or (ii) the frame at the second frame end,
• (C) in response to the second end of the intermediate storage section of the cable being pulled away from the frame, the slideable block is drawn to the second frame end until the latch part engages the staple catch and prevents the spring from pulling the slideable block and the first pulley back toward the first frame end, and
• (D) in response to the latch part releasing the staple catch, the spring pulls the slideable block and the first pulley back toward the first frame end and retracts the withdrawn portion of the intermediate storage section of the cable back toward the frame, the first pulley being the sole pulley pulled back toward the first frame end.
