ABSTRACT:
A bar lock for securing a door in a closed position in a frame includes a bar that forms a first interlocking profile extending along its length. The bar is mounted for rotation in first and second hinges by first and second hinge elements. The first and second hinge elements define a second interlocking profile shaped to mate with the first interlocking profile to restrict the hinge elements to axial movement along the length of the bar. The interlocking profiles maintain alignment and facilitate welding of the hinge elements in place on the bar. A similar approach can be used to facilitate assembly of a handle bracket to the bar. An elastomeric strip is affixed in a groove extending along the length of the bar to cushion contact between the bar and the door.
