US Patent 8186728 Draw latch with safety catch

A draw latch with a safely catch for fastening two members, where the latch comprises a base attached to one of the two members, a lever pivotally connected to the base for movement between closed and open positions, a draw bar pivotally connected at one end with the lever providing toggle action upon the latch lever closing and another end of the draw bar is for engagement with a draw plate attached to the other of the two members. The safety catch comprises a safety catch bolt with thumb knob, with the colt biased into a locked position by a compression spring to prevent the latch from opening. The safety catch can be placed into an open position by pushing the knob, so the safety catch bolt will disengage from a sidewall of the lever, allowing the lever to be lifted to open the latch.
