Patent ID: 7878558

Claim:
An assembly comprising: a back plate mountable to a stationary or movable member; said back plate connectable to two front plates, wherein a portion of each of said front plates is angled outwardly from said back plate, said back plate comprising a trigger mechanism capable of interdependently actuating said front plates, said front plates forming a bounded area for receiving at least an end of a bracketed rod; said back plates and front plates forming a receiver; said trigger mechanism comprising a center support and arcuate arms extending therefrom, each of said arms connected to a ring portion on the backside of an adjacent front plate, a portion of each of said arms passing through a center of a spring mounted between the back plate and its adjacent front plate; a bracketed rod mountable to the other one of the stationary or movable member, wherein a distal end of the rod engages the bounded area when it swings partially through the receiver in an arc pattern, the rod further being slidable horizontally along a longitudinal axis relative to its respective stationary or movable member to release the rod end from the bounded area; either of said front plates capable of being urged by said rod end to allow its entry into said bounded area, an end of said trigger mechanism oscillating a corresponding front plate toward a compressed mode during the travel of said rod end into the bounded area, an opposing end of said trigger mechanism oscillating a corresponding front plate toward an expanded mode to obstruct the travel of said rod end and causing said rod end to make a contact with said trigger mechanism which also serves as an end stop to discontinue the travel of said rod end; and wherein said trigger mechanism oscillates to urges said front plates to their original positions to positively lock said rod end in said bounded area, thereby preventing gate swing through and/or bounce back even after a forceful contact between said rod end and said front plate occurs.
