<p>A latch includes an angled bracket having a front 120 and a rear 122 flanges with holes 124, 126 locating a cylindrical bolt 102, a bolt handle 104, and a coil spring 106. The angled bracket includes at least two substantially orthogonal contiguous sides 114, 116 which contain a substantially U-shaped slot. The bolt handle extends through the slot and the spring biases the bolt forward to a latched position. In order to move the bolt to the unlatched position, the bolt must be both rotated and translated for the bolt handle to move through the U-shaped slot. The slot is preferably formed with an additional forward bend 128d so that the bolt must be translated, rotated, and translated again to be moved to an unlatched position. The angled bracket is preferably formed with five sides and is provided with mounting holes 130, 132 for attaching it to a cage. The disclosed bolt is formed as a stepped cylinder to provide a point 110 of annular engagement with the spring.</p> |
