Portable auxiliary door lock

An auxiliary lock for securing a hinged door comprising:

• an elongate, substantially uniform thickness slide bar having a first face, an opposite second face, and a slide bar hook extending in a first direction and defining an included angle of about 90.degree. with said slide bar first face;
• a lock cylinder having at least a rear element, and axial positioning means for axially positioning said lock cylinder along said slide bar;
• said lock cylinder adjacent said first face of said slide bar and extending in the first direction;
• said rear element including an extension and a door stop extending in a second direction, said door stop defining an included angle of about 90.degree. with said lock cylinder extension;
• a spacer element selectively positionable along said slide bar;
• said spacer element comprises at least a block of material defining a passage asymmetrically positioned therethrough to provide a relatively thin retainer side and a relatively thick spacer side, whereby;
• said slide bar hook is inserted within a door bolt recess of a door jamb;
• said lock cylinder and said door stop are selectively positioned along said slide bar to allow the door to be closed and latched, and said lock cylinder is slide along said slide bar toward the door until said door stop is in contact with the door, and said spacer element is located between a door edge and an associated door jamb to hold said slide bar securely in position and hold said slide bar hook securely within a door bolt recess.

• a lock cylinder including a rear element and an axial passage receiving said slide bar in a sliding arrangement;
• said lock cylinder adjacent said first face of said slide bar and extending in the first direction;
• said rear element including an extension and a door stop extending in a second direction substantially opposite from the first direction, said door stop defining an included angle of about 90.degree. with said rear element extension;
• retaining means for retaining said rear element extension closely adjacent said slide bar second face;
• said retaining means further comprises two oppositely positioned ears extending from said rear element extension, said ears engaging said slide bar in a sliding arrangement;
• and
• a spacer element surrounding said slide bar and compressed between a door edge and an associated door jamb, whereby said slide bar hook is inserted within a door bolt recess of a door jamb;
• said lock cylinder and said door stop are selectively positioned along said slide bar to allow the door to be closed and latched, and said lock cylinder is slid along said slide bar toward the door until said door stop is in contact with the door.
