ABSTRACT:
A safety mechanism for weightlifting devices checks the uncontrolled descent of weights and/or other structures. Using aligned or other slots, a pawl or dog is biased against the surface containing such slots. In order to operate the weightlifting device, the pawl or dog must be actively disengaged from the slots. Exercise can then occur. However, should the weightlifter's grip relax and release the release lever, the associated biasing system forces the engagement end of the dog into one of the aligned slots halting the further downward travel of the associated weights in supporting structures. An associated weightlifting device is disclosed having a latching mechanism enabling securement of the device in a lowered position.
