  "abstract": "An emergency access tool is designed to unfold into unique geometrical shapes that allow for the tool to act as a Class 1 lever to access a locked privacy partition stall door from the outside area thereof. The tool provides a handle to impart input force, a shaft rotatable out of a collapsed position of storage within the handle into alternative fixed operating positions with respect to the handle, a proximal portion of the shaft having a reduced diameter intermediate section, the intermediate section providing a fulcrum point where leverage is achieved while the tool is inserted within the door seam of the partition, and a distal end section which maintains a substantially perpendicular orientation with respect to the shaft during use of the tool. The end section of the tool is sized and adapted to make contact with the interior door lock of the partition and impart the output force necessary to unlock the lock latch and allow entry into the privacy partition stall.",

  "description_excerpt": "Instances are known to occur when a user of a privacy partition stall, such as a bathroom stall or fitting room, may encounter a distressful situation where said user of the stall may be unable to work the lever of the stall door latch lock and allow the stall door to be opened. Unfortunately current methods to gain access to a locked stall door to provide assistance to a person who has for some reason become incapacitated inside the stall involve either crawling under the stall door or climbing over the stall door or a wall of the stall partition. Stall door manufacturers do offer doors that can be lifted up and swung outward to gain access, but this method is cumbersome, time consuming and potentially dangerous, should the first responder lose control of the door and injure the person in distress. After extensive research this inventor decided to improve over these inefficient methods of reaching such a person to provide them aid.\n\nTools were known in the relevant art for emergency opening of doors for access to the interiors of dwellings and vehicles.\n\nOne category of the existing art addresses the need to gain access to the interior of a locked vehicle from a location exterior to the vehicle operator's compartment. In this application locksmiths commonly use tools which include probe-like portions which can be inserted between the glass window of a vehicle and the hollow door supporting the window and which include end portions that are designed to manipulate the locking mechanism in the interior of the door. Examples of such devices are shown in Fanberg U.S. Pat. No. 4,683,783, Parkins U.S. Pat. No.",
