ABSTRACT:
The disclosure describes a latch retaining device to maintain the latch of a door in an inoperable position, which includes at least one body member adapted to engage and grip the door knob of the door so as to retain the door knob in its latch releasing rotated position indefinitely. The body member of the device may have first and second ends with the first end thereof adapted to frictionally engage the door adjacent the position of the door knob, whereby frictional engagement between the device and the door as well as the door knob enable the door knob to be maintained in a position to render the door latch inoperative. Alternatively, the body member may frictionally engage a door knob and exert an appropriate force thereon to maintain it in a latch releasing position. The at least one body member is secured in its frictionally engaging position by means of a cincturing strap associated with the body member. The body member is adapted to frictionally engage any variety of door knob and to assuredly allow the door knob to be maintained in its latch releasing rotated position. The at least one body member may be provided with various structures to facilitate placement of device in its operative position on a door knob to enable easy and effective use of the device. The device provides a simple and cost effective structure to maiantain a door latch in an inoperative position for free movement of the door as desired under many circumstances.
