Mountable resistance exercise device

A portable exercise device comprising:

• a. a rigid enclosure having an outer wall that defines an internal space therein, the rigid enclosure including a first cable aperture and a second cable aperture, a present resistance setting on an exterior surface of said rigid enclosure, an electronic command circuit board, a motor also within said enclosure, and a source of power to provide power to the electronic command circuit board;
• b. a shaft rotatably affixed within said rigid enclosure, both a first spool and a separate second spool affixed around said shaft and rotatable when said shaft rotates, a first flange affixed to said shaft and positioned to one side of said first spool, a second flange affixed to said shaft and positioned between and separating the first spool from the second spool, a third flange affixed to said shaft and located on a side of the second spool remote from said first flange, each of the first flange, the second flange and the third flange rotate when said shaft and said first spool and said second spool rotate;
• c. a first cable wrapped around said first spool and extending through the first cable aperture and affixed at a distal end to a first grip element, a second cable wrapped around said second spool and extending through the second cable aperture and affixed at a distal end to a second grip element, pulling on each of said first cable and said second cable through a respective grip element causes said first spool, said second spool, said first flange, said second flange and said third flange to rotate in a first direction;
• d. a sensor target affixed to and rotatable with a rotatable member selected from the group consisting said shaft and at least one of said first flange, said second flange and said third flange;
• and
• e. a proximity sensor in wireless communication with said sensor target, said proximity sensor detects rotation of said sensor target and upon detection of the rotation of said sensor target, said proximity sensor transmits a signal to said electronic command circuit board which transmits a signal to said motor which creates said preset resistance setting on said shaft which provides the preset resistance to each of said first cable and said second cable when each respective cable is unwound from a respective spool.

• b. shaft rotatably affixed within said rigid enclosure, at least a first spool affixed around said shaft and rotatable when said shaft rotates, at least a first flange affixed to said shaft and positioned to one side of said first spool and, a second flange affixed to said shaft and positioned at an opposite side of said first spool, each of the first flange and second flange rotate when said shaft and first spool rotate;
• c. at least a first cable wrapped around said first spool and extending through at least said first cable aperture and affixed at a distal end to a first grip element, pulling on said first cable through a respective grip element causes said first spool, said first flange, and said second flange to rotate;
• d. a sensor target affixed to and rotatable with a rotatable member selected from the group consisting said shaft and at least one of said first flange and second flanges;
• and
• e. rotation of said sensor target causes the proximity sensor to transmit a signal to said electronic circuit board which in turn transmits a signal to said motor to create a preset resistance on said shaft which provides the preset resistance to said first cable when said first cable is unwound from said first spool.
