of the spread free end 304 greater than the diameter of the corresponding first aperture 232 233 of the other side wall 222 223 so that the spread free end 304 will secure the pawl 270 with the housing 220 at the other end accordingly the rivet 300 is supported by the housing 220 at a fixed location relative to the housing 220 the rivet 300 is also adapted for allowing the pawl 270 to move and slide upwardly and downwardly and forwardly and rearwardly via the slotted aperture 286 of the pawl 270 when the crank member 250 is actuated in other words the pawl 270 moves in a combination of translational and pivotal motions as the pawl 270 moves from the latched position to the unlatched position the means for actuating the crank member such as a rod 110 is rotatably moveable about a longitudinal axis thereof some examples of the means for actuating the crank member are a rod 110 a knob member a rod connected to an actuating system having a handle adapted for rotatably moving the rod 110 and any other actuating means known in the art the means for actuating the crank member such as a rod 110 is adapted for being positioned through the second apertures.
