Door holding device and safety system

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

• providing a door holding device comprising:
• a first arm assembly pivotally attached to a second arm assembly,
• a movable clamping mechanism slidably attached to the first arm assembly by a sliding component comprising screw threading operatively connected to a quick thread system of the first arm assembly, wherein the quick thread system includes a nut and a slide button, and
• a holder disposed at a proximate end of the second arm assembly configured to attach to an end of a door to secure the door in the partially open configuration that is relative to a door frame, wherein the holder comprises a bracket configured to slide along a longitudinal portion of the second arm assembly to vary the position of the holder along the longitudinal portion of the second arm assembly;
• placing the first arm assembly against the door frame, whereby a longitudinal part of the first arm assembly contacts an end face of the door frame and a first rotatable pad on a stationary part of the first arm assembly contacts one side of the door frame;
• actuating the slide button operatively connected to the sliding component of the movable clamping mechanism so as to disengage the screw threading from the quick thread system of the first arm assembly;
• sliding the movable clamping mechanism along the longitudinal part of the first arm assembly toward an opposite side of the door frame;
• contacting the opposite side of the door frame with a second rotatable pad on the movable clamping mechanism;
• disengaging the slide button so as to engage the screw threading with the quick thread system of the first arm assembly;
• tightening the rotatable pad against the opposite side of the door frame;
• compressing the first rotatable pad on the stationary part against the one side of the door frame;
• and
• placing a vertical end of the door into the holder on the second arm assembly to secure the door in the partially open configuration.

A door holding system comprising:

• a door holding device including:
• a first arm assembly;
• a second arm assembly;
• a pivot device that pivotally connects the first arm assembly to the second arm assembly;
• a movable clamping device slidably attached to the first arm assembly by a sliding component comprising screw threading operatively connected to a quick thread system of the first arm assembly, wherein the quick thread system includes a nut and a slide button and wherein the movable clamping device clamps to a structure to secure the door holding device to the structure such that the structure is between the movable clamping device and a stationary portion of the first arm assembly:
• a holder disposed at a proximate end of the second arm assembly configured to attach to an end of a door to hold the door in a partially open position relative to the structure,
• wherein the holder comprises a bracket configured to slide along a longitudinal portion of the second arm assembly to vary the position of the holder along the longitudinal portion of the second arm assembly;
• and
• an electronic wireless communicator disposed in or on the door holding device,
• wherein the wireless communicator provides electronic communications to and/or from an external electronic communicating system.
