Door holding device and safety system

A method of securing a door in a partially open configuration comprising:

• providing a door holding device having a first arm assembly, a second arm assembly, and a movable clamping mechanism;
• placing the first arm assembly against a door frame, whereby a longitudinal part of the first arm assembly contacts an end face of the door frame and a stationary part of the first arm assembly contacts one side of the door frame;
• actuating a release lever located on the movable clamping mechanism so as to disengage the release lever from a corresponding recess of a plurality of recesses defined in a track in the longitudinal part such that the movable clamping mechanism is movable along the longitudinal part;
• moving the movable clamping mechanism along the longitudinal part toward the door frame;
• contacting an opposite side of the door frame with a movable pad on the movable clamping mechanism;
• tightening the movable pad against the opposite side of the door frame;
• compressing the movable pad against the opposite side of the door frame;
• compressing a stationary pad on the stationary part against the one side of the door frame;
• and
• placing a vertical end of the door into a generally U-shaped holder of the second arm assembly.

A door holding system comprising:

• a door holding device including:
• an first arm assembly including a first longitudinal part and a stationary part that form an L-shape, wherein the first longitudinal part includes two channels disposed on two sides of the first longitudinal part, respectively, and a track having recesses defined therein;
• a second arm assembly pivotally attached to the first arm assembly;
• and
• a movable clamping mechanism slidably attached to the first arm assembly that clamps to a structure to secure the door holding device to the structure, wherein the movable clamping mechanism includes a traveler that slides along the track, and wherein the traveler includes:
• a quick release lever that engages one of the recesses to hold the traveler in a corresponding position along the track, and
• an extension part having a threaded aperture defined therein, and wherein the extension part extends in a direction from the traveler such that the stationary part and the extension part are substantially parallel to each other and form an approximate U-shape with the first longitudinal part;
• and an electronic wireless communicator disposed in or on the door holding device,
• wherein the wireless communicator provides electronic communication to and/or from an external electronic communicating system.
