Support arm assembly for a safe lid

This support arm assembly for connection between a safe's lid and base has two main parts, a bracket for connection to the safe's base and a linear support arm that connects between the bracket and the lid. The bracket has a generally "L" shaped cross-section with a side face adapted for connection to the inside of the safe's base proximate its upper edge. The other face of the "L" shaped bracket serves as its upward facing side and is provided with a linear slot that is parallel to the side of the safe when the bracket is mounted. The linear support arm has a generally flat planar configuration that is adapted for placement through the linear slot in the bracket transverse to the upward facing side of the bracket. It is slidable in the slot parallel to the side face of the bracket and the side of the safe. The linear support arm has an upper end pivotally connected to the safe lid. The lower end or the linear support arm has a bend that prevents it from being withdrawn from the slot once it is put into place. It also has an abrupt edged notch adjacent the bend in the lower edge of the linear support arm that is adapted to interlock with the slot by dropping into the slot when the box lid is opened.
