Abstract:
1. A safety assist device for use with an elongated weight bar for supporting said weight bar in the event of a user failure or fatigue during weightlifting exercises, the safety assist device comprising: at least two pairs of elongated, spaced apart arms, each pair of arms oriented to receive a respective end of said weight bar therethrough so as to permit said weight bar to move along a length of each pair of arms; a bar-sensing apparatus including at least two sensors intermittently located along at least a portion of the length of said arms, said at least two sensors operable to collectively determine at least one parameter related to the velocity of the bar as the bar moves along the length of the pairs of arms; and a support associated with each pair of arms respectively and including a shiftable, bar-supporting element operable to extend along at least a portion of the length of its respective pair of arms, wherein said supports are operable to shift said bar-supporting elements to a bar-supporting position so as to completely arrest movement of said weight bar and to completely support said weight bar in the event that said at least one parameter is outside of a predetermined parameter range due to the user failure or fatigue.
