| 20140151487 | SPEED CONTROL FOR CABLE RETRACTOR - The present invention is a speed control for a cable retractor. The cable retractor with which the speed control is used comprises a pulley that engages a cable that may be extended and retracted. A friction element configured to adjustably contact the cable adjacent to the pulley is attached to a movable linkage. The movement of the linkage is constrained to move along a predetermined path such that movement of the linkage along the path alters the distance between the friction element and the pulley. In one or more embodiments a cantilevered spring is attached to the linkage. An adjustable control, for example a thumbscrew, is configured to move the spring in relation to the linkage in a manner that alters the position of the friction element with respect to the cable and/or the pressure exerted by the friction element on the cable. | 06-05-2014 |

| 242381400 | Tension responsive | 1 |
| 20150076272 | FAILURE COMPENSATING LACE TENSION DEVICES AND METHODS - A reel for tightening an article includes a housing and a spool positioned within the housing. A knob is coupled with the spool to cause the spool to rotate within the housing and thereby wind a tension member about a central post of the spool. A load holding mechanism is coupled with the spool and the housing and includes a first friction element and a second friction element that are frictionally engageable to prevent rotation of the spool in a second direction to prevent unwinding of the tension member from the spool's central post. Rotation of the knob in a first direction reduces frictional engagement of the friction elements to enable rotation of the spool in the first direction and tension in the tension member biases the spool toward rotation in the second direction which increases the frictional engagement of the friction elements. | 03-19-2015 |

| 20140263799 | Retractor Mechanism For Collars - A retractor mechanism for a pet collar. The mechanism includes a case with a cavity, a spool assembly with a spool plate, a line wound on the spool assembly with a free end exiting the case that is attached to a leash handle, a power spring that biases the spool assembly to a wound state, and a centrifugal/inertial brake having with a lock member with a heavier distal end a lighter proximal end, and lock member spring. The lock member pivots on the spool plate. When the spool assembly is spun above a threshold rotations speed, a centripetal force acting on the distal end of the lock member exceeds a spring force of the lock member spring acting on the proximal end of the lock member, thereby pivoting the lock member into contact with a catch in the cavity of the case to prevent the spool assembly from rotating further. | 09-18-2014 |
