What is dead mans grip?

Answer 1

Wow. I liked the question, don't know but wanted to looked around. According to one link (http://www.answerbag.com/q_view/664463 )It is a grenade, lethal or non lethal, that is built into the handle of a gun. It is primed by squeezing the trigger and if the user lets go of the grip then the grenade goes off. It could be useful as a grenade if you run out of ammunition or if your opposition is too powerful when you are forced to hand your weapons over. Also from the Weightlifting world ( http://www.patentstorm.us/patents/7083552.html ):

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.
